[0036] The embodiments according to the present disclosure will now be described in more detail with reference to the accompanying drawings. However, these embodiments may be implemented in various different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present disclosure thorough and complete, and to fully convey the concepts of these embodiments to those skilled in the art.
[0037] As shown in FIG. 1 to FIG. 24, embodiments of the present disclosure provide a base station 200 and a cleaning robot system. The cleaning robot system includes a self-moving cleaning device 100 and the base station 200, i.e., the base station 200 and the self-moving cleaning device 100 are used in cooperation.
[0038] Further, as shown in FIG. 1 and FIG. 2, the self-moving cleaning device 100 may include a machine main body 110, a perception system 120, a control module, a driving system 140, a cleaning system 150, an energy system and a human-machine interaction system 170. It can be understood that the self-moving cleaning device 100 may be a self-cleaning device or other self-moving cleaning devices 100 that meet requirements. The self-moving cleaning device 100 is a device that automatically performs, without user operations, a cleaning operation in a certain region to be cleaned. When the self-moving cleaning device 100 starts to work, the self-moving cleaning device 100 starts from the base station 200 to perform a cleaning task. When the self-moving cleaning device 100 completes the cleaning task or needs to stop the cleaning task, the self-moving cleaning device 100 may return to the base station 200 for operations such as charging, and/or water replenishing, and/or washing, and/or dust collection.
[0039] As shown in FIG. 1, the machine main body 110 includes a forward portion 111 and a backward portion 112, is approximately circular, and may also be in other shapes including, but not limited to, an approximately D shape with a square front and a circular rear, and a rectangular or square shape with a square front and a square rear.
[0040] As shown in FIG. 1, the perception system 120 includes a position determining apparatus 121 located on the machine main body 110, a collision sensor and a proximity sensor which are arranged on a buffer 122 of the forward portion 111 of the machine main body 110, a cliff sensor arranged at the lower part of the machine main body 110, and a magnetometer, an accelerometer, a gyroscope, an odometer and other sensing apparatuses which are arranged inside the machine main body 110 for providing various position information and motion state information of the machine to the control module. The position determining apparatus 121 includes, but is not limited to, a camera and a laser distance sensor (LDS).
[0041] As shown in FIG. 1, the forward portion 111 of the machine main body 110 may carry the buffer 122. When a driving wheel module 141 propels the self-moving cleaning device 100 to travel on the ground during cleaning, the buffer 122 detects one or more events in a traveling path of the self-moving cleaning device 100 via a sensor system thereon, such as an infrared sensor. Based on the event detected by the buffer 122, for example obstacles and walls, the self-moving cleaning device 100 may control the driving wheel module 141, so that the self-moving cleaning device 100 makes a response to the event, for example, get away from the obstacles.
[0042] The control module is arranged on a main circuit board in the machine main body 110, and includes a computing processor, such as a central processing unit and an application processor, which is communicated with a non-transitory memory, such as a hard disc, a flash memory and a random access memory. The application processor draws an instant map of the environment where the self-moving cleaning device 100 is located based on obstacle information fed back by the laser distance sensor by using a positioning algorithm, for example simultaneous localization and mapping (SLAM). In addition, by combining the distance information and speed information fed back by the sensors, the cliff sensor, the magnetometer, the accelerometer, the gyroscope, the odometer and other sensing apparatuses which are arranged on the buffer 122, a comprehensive judgment may be made on the current working state and position of the self-moving cleaning device 100, as well as the current posture of the self-moving cleaning device 100, such as crossing a doorsill, moving onto a carpet, being at a cliff, being stuck from above or below, and having a full dust box, being picked up, etc. Specific next action strategies are given according to different situations, such that the self-moving cleaning device 100 has better sweeping performance and user experience.
[0043] As shown in FIG. 2, the driving system 140 may manipulate the machine main body 110 to travel across the ground based on a driving command with distance and angle information, for example, components of x, y and theta. The driving system 140 includes the driving wheel module 141, and the driving wheel module 141 may control both a left wheel and a right wheel simultaneously. In order to control the movement of the machine more accurately, in some examples, the driving wheel module 141 includes a left driving wheel module and a right driving wheel module. The left and right driving wheel modules are arranged along a transverse axis defined by the machine main body 110. In order for the self-moving cleaning device 100 to be able to move more stably on the ground or have stronger mobility, the self-moving cleaning device 100 may include one or more driven wheels 142, including but not limited to universal wheels. The driving wheel module 141 includes a traveling wheel, a driving motor and a control circuit for controlling the driving motor. The driving wheel module 141 may also be connected to an odometer, and a circuit for measuring a driving current. The driving wheel may have an offset drop-down suspension system and be movably fastened, for example, be rotatably attached to the machine main body 110 and receive a spring offset biased downward and away from the machine main body 110. The spring offset allows the driving wheel to maintain contact and traction with the ground with a certain landing force, while a cleaning element 183 of the self-moving cleaning device 100 is also in contact with the ground with a certain pressure.
[0044] The energy system includes a rechargeable battery, such as a nickel-hydrogen battery and a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detection circuit and a battery undervoltage monitoring circuit which are then connected to a single chip microcomputer control circuit. A main unit is connected to the base station 200 through a charging electrode arranged at the side or below the machine main body for charging.
[0045] The human-machine interaction system 170 includes buttons on a panel of the main unit for a user to select functions, and may also include a display screen and/or an indicator light and/or a horn. The display screen, the indicator light or the horn presents the current state or function options of the self-moving cleaning device to the user. The human-machine interaction system may also include a mobile phone client program. For a path navigation type self-moving cleaning device 100, the mobile phone client may show the map of the environment where the device is located and the location, as well as a position of the device, thereby providing the user with richer and more user-friendly function options.
[0046] As shown in FIG. 2, the cleaning system 150 includes a dry cleaning system 151, that is, the self-moving cleaning device 100 may be a sweeper, or the cleaning system 150 includes a wet cleaning system and the dry cleaning system 151, that is, the self-moving cleaning device 100 may be a sweeping and mopping integrated machine.
[0047] As shown in FIG. 2, the dry cleaning system 151 according to the embodiment of the present disclosure may include a rolling brush, a dust box and a dust suction fan. The rolling brush with certain interference with the ground sweeps up debris on the ground and rolls the debris up to the front of a dust suction port between the rolling brush and the dust box, and the debris is then sucked into the dust box by an airflow having a suction force that is generated by the dust suction fan and passes through the dust box. The dry cleaning system 151 may further include a side brush 152 having a rotating shaft, and the rotating shaft is angled relative to the ground for moving particulates into a rolling brush region of the cleaning system 150.
[0048] As shown in FIG. 3, FIG. 4, FIG. 5, and FIG. 6, the dust box 160 of the self-moving cleaning device 100 according to the embodiment of the present disclosure is provided with a debris storage chamber 162, and an air inlet 163 and a dust exhaust port 164 which are communicated with the debris storage chamber 162. The dust box 160 is also provided with a dust inlet 166 and an air vent port 1601 which are communicated with the debris storage chamber 162. The dust inlet 166 is communicated with the dust suction port of the self-moving cleaning device 100 through a dust suction duct. The dust suction fan of the self-moving cleaning device 100 is communicated with the air vent port 1601 of the dust box 160. A filter part 161 is arranged at the air vent port 1601. The airflow with a suction force generated by the dust suction fan in operation will suck the debris on the surface to be cleaned into the dust box 160 through the dust suction port, the dust suction duct and the dust inlet 166, and after being filtered by the filter part 161 at the air vent port 1601, the dust suction airflow will be exhausted from the air vent port 1601 through the dust suction fan. Thus, the debris can be collected in the dust box 160, and the provided filter part 161 can prevent the debris in the dust box 160 from entering the dust suction fan, which in turn is beneficial for prolonging the service life of the dust suction fan.
[0049] It should be noted that, as shown in FIG. 3, the machine main body 110 of the self-moving cleaning device 100 is also provided with a dust outlet 169. A dust exhaust channel 168 through which the dust exhaust port 164 and the dust outlet 169 are communicated is arranged inside the machine main body 110. The base station 200 is provided with a dust collection port 2115 and a dust collection assembly 260 communicated with the dust collection port 2115. When the self-moving cleaning device 100 is docked at the base station 200, and after the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 on the base station 200, the dust collection assembly 260 on the base station 200 works, and the airflow flows in from the air inlet 163 of the dust box 160, passes through the dust exhaust port 164 and the dust exhaust channel 168, and flows into the base station 200 from the dust outlet 169 and the dust collection port 2115 that are butted with each other, such that the debris from the dust box 160 is collected into the base station 200, thereby achieving the dust collection operation.
[0050] One-way valves are arranged at both the air inlet 163 of the dust box 160 and the dust exhaust port 164 of the dust box 160. When cleaning impurities in the dust box 160, that is, during the dust collection operation on the self-moving cleaning device 100 by the base station 200, the valves at the air inlet 163 and the dust exhaust port 164 of the dust box 160 are both opened, such that the airflow generated in the dust box 160 can take away the impurities more easily. The specific structure of the dust box 160 will be described in detail later.
[0051] As shown in FIG. 7 and FIG. 8, the base station 200 according to the present disclosure further includes a base station housing 210 and the dust collection assembly 260, and the base station housing 210 is provided with the dust collection port 2115. When the self-moving cleaning device 100 is docked at the base station 200, the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 on the base station 200 for the dust collection operation. In some examples, the base station 200 is provided with an accommodating cavity 211. When the self-moving cleaning device 100 is docked at the base station 200, at least part of the self-moving cleaning device 100 is accommodated in the accommodating cavity 211, and the dust collection port 2115 is located in the accommodating cavity 211. In some examples, the dust collection port 2115 may be located on the sidewall of the accommodating cavity 211.
[0052] As shown in FIG. 9, FIG. 10 and FIG. 13, the dust collection assembly 260 includes a dust collection apparatus 261, and a dust bag compartment 215, a noise reduction housing 262, a dust collection duct 263 and a dust collection fan 264 which are arranged in the base station housing 210. The dust collection apparatus 261 is arranged in the dust bag compartment 215, and the noise reduction housing 262 is provided with an air exhaust port 2621. The dust collection duct 263 communicates the dust collection port 2115, the dust bag compartment 215 and the noise reduction housing 262 to form a dust collection air duct, and the dust collection fan 264 is arranged on the dust collection air duct to generate a dust collection airflow. The dust collection airflow generated by the dust collection fan 264 brings the debris in the dust box 160 of the self-moving cleaning device 100 into the dust collection apparatus 261 through the dust collection port 2115, after collected and intercepted by the dust collection apparatus 261, the debris is accommodated in the dust collection apparatus 261, and the dust collection airflow is exhausted from air exhaust port 2621. Since the dust collection airflow generated by the dust collection fan 264 in operation will be exhausted through the air exhaust port 2621 on the noise reduction housing 262, the noise reduction housing 262 can perform noise reduction on the dust collection airflow flowing therethrough. Therefore, the dust collection airflow of the dust collection air duct will be exhausted after being noise-reduced by the noise reduction housing 262, thereby greatly reducing an aerodynamic noise of the dust collection fan 264, reducing a working noise of the fan and improving a comfort level of the user. The dust collection apparatus 261 may be a dust bag or other components that meet the requirements.
[0053] In some examples, as shown in FIG. 9, the dust collection duct 263 includes a first dust collection duct 2631 and a second dust collection duct 2632. The first dust collection duct 2631 communicates the dust collection port 2115 to the dust bag compartment 215, and the second dust collection duct 2632 communicates the dust collection fan 264 to the noise reduction housing 262. Under the condition that the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 of the base station 200, as shown in FIG. 3, FIG. 9 and FIG. 13, the dust collection airflow generated by the dust collection fan 264 flows into the dust bag in the dust bag compartment 215 by the dust box 160, the dust exhaust channel 168, the dust outlet 169 and the dust collection port 2115 of the self-moving cleaning device 100 through the first dust collection duct 2631, and the dust collection airflow brings the debris in the dust box 160 into the dust collection apparatus 261. After the debris is collected and intercepted by the dust collection apparatus 261, the dust collection airflow flows from the dust bag compartment 215 into the noise reduction housing 262 through the dust collection fan 264 and the second dust collection duct 2162, and is exhausted into the base station housing 210 through the air exhaust port 2621 of the noise reduction housing 262. The noise reduction housing 262 is used for performing noise reduction on the airflow flowing therethrough to achieve the purpose of reducing the working noise of the dust collection fan 264 and improve the comfort level of the user.
[0054] In some embodiments according to the present disclosure, a first sound absorbing member 2629 is arranged in the noise reduction housing 262, and the first sound absorbing member 2629 may be a component made of sound absorbing cotton or other sound absorbing materials. By arranging the first sound absorbing member 2629 in the noise reduction housing 262, the dust collection airflow flowing through the noise reduction housing 262 can be subjected to noise reduction, thereby further improving the noise reduction performance of the noise reduction housing 262.
[0055] It can be understood that in the dust collection assembly 260 according to the present disclosure, the noise reduction housing 262 is additionally arranged at the tail end of the dust collection air duct, such that the dust collection airflow is not directly exhausted by the dust collection fan as in the embodiment in the related art, but is exhausted by the noise reduction housing 262 connected to the dust collection fan 264, enabling the dust collection airflow to continue flowing in the noise reduction housing 262 before being exhausted. Therefore, the purpose of noise reduction can be achieved by using the first sound absorbing member 2629 arranged in the noise reduction housing 262, so as to further ensure a better noise reduction effect and reduce the working noise of the dust collection fan 264.
[0056] In some embodiments according to the present disclosure, as shown in FIG. 12 and FIG. 19, the base station housing 210 is also provided with an air outlet 2119, and the air exhaust port 2621 is not opposite to the air outlet 2119. In other words, after being exhausted from the air exhaust port 2621 of the noise reduction housing 262, the dust collection airflow will flow into the base station housing 210 and be exhausted to the external environment through the air outlet 2119 formed on the base station housing 210. The air exhaust port 2621 is not opposite to the air outlet 2119, such that a propagation channel of the dust collection airflow between the air exhaust port 2621 and the air outlet 2119 is a bent channel, that is, the working noise of the dust collection fan 264 needs to be exhausted from the air outlet through the bent propagation channel between the air exhaust port 2621 and the air outlet 2119. Since the bent propagation channel plays a role of blocking the sound from propagation outward and can enhance the friction and dissipation of sound waves, the purpose of noise reduction is once again achieved when the dust collection airflow is exhausted to the external environment through the air exhaust port 2621 and the air outlet 2119, which reduces the influence of the noise on the user and in turn is beneficial for improving the use comfort level of the user.
[0057] In the above embodiment, as shown in FIG. 12, the base station housing 210 includes four body sidewalls 2109 connected in sequence to define a frame structure. Further, the accommodating cavity 211 for accommodating the self-moving cleaning device 100 on the base station 200 may be located on one of the four body sidewalls 2109 located in the front of the base station 200, and the front of the base station 200 may be as shown in FIG. 7. The air exhaust port 2621 is opposite to one of the body sidewalls 2109, and the air outlet 2119 may be arranged on other body sidewalls 2109. Thus, it can be ensured that the propagation channel of the dust collection airflow between the air exhaust port 2621 and the air outlet 2119 is a bent channel to ensure a better noise reduction effect.
[0058] The air outlet 2119 may be formed on one, two or three of other three body sidewalls 2109 except the body sidewall opposite to the air exhaust port 2621. In some embodiments, the air outlet 2119 may also be formed on the body sidewall opposite to the air exhaust port 2621 as long as the air outlet 2119 is not opposite to the air exhaust port 2621. For example, the air outlet 2119 is arranged away from the air exhaust port 2621.
[0059] As shown in FIG. 11, in some embodiments according to the present disclosure, the dust collection fan 264 is provided with a second sound absorbing member 2641. The second sound absorbing member 2641 is used for performing sound absorption on the dust collection airflow flowing through an air outlet port of the dust collection fan 264, thereby further reducing the aerodynamic noise of the dust collection fan 264, reducing the working noise of the dust collection fan 264 and improving the comfort level of the user.
[0060] Further, the second sound absorbing member 2641 is also configured to filter the dust collection airflow flowing through the air outlet port of the dust collection fan 264. For example, the second sound absorbing member 2641 may be sound absorbing filter cotton, such that the second sound absorbing member 2641 further has the function of filtering. That is, the second sound absorbing member 2641 plays a role of not only reducing the noise and but also re-filtering the dust collection airflow, and can filter the dust collection airflow flowing out of the air outlet port of the dust collection fan 264 while greatly reducing the working noise of the dust collection fan 264. Thus, the cleanliness of the airflow exhausted to the external environment can be improved.
[0061] Further, impurities such as carbon powder will be generated during working of the dust collection fan 264, and these impurities may also be filtered by the second sound absorbing member 2641. In other words, the second sound absorbing member 2641 can not only filter the dust collection airflow from the dust box 160, but also filter the impurities such as carbon powder generated by the dust collection fan 264 in work, which further improves the cleanliness of the airflow exhausted to the external environment and reduces environmental pollution.
[0062] As shown in FIG. 10 and FIG. 11, in the above embodiment, the dust collection fan 264 is a vortex fan. The vortex fan is compact in size, high in pressure and fast in wind speed, can meet the design requirement of the base station 200 for a small size, and in addition, can ensure higher dust collection efficiency and better dust collection effect.
[0063] The vortex fan is provided with a vortex cavity 2642 and a transition cavity 2643 which are communicated through an air passing port 2644; an air inlet port is formed on the cavity wall of the vortex cavity 2642; the air outlet port is formed on the cavity wall of the transition cavity 2643; and the second sound absorbing member 2641 is located in the vortex cavity 2642. Thus, the second sound absorbing member 2641 can be utilized to perform sound absorption and filtering operations on the dust collection airflow flowing from the vortex cavity 2642 to the transition cavity 2643, as shown in FIG. 11.
[0064] As shown in FIG. 9, FIG. 13 and FIG. 14, in some embodiments according to the present disclosure, the dust bag compartment 215 is provided with an airflow inlet 2151 and an airflow outlet 2152, the dust collection apparatus 261 is communicated with the airflow inlet 2151, the air inlet port of the dust collection fan 264 is connected to the airflow outlet 2152, and the air outlet port of the dust collection fan 264 is connected to the noise reduction housing 262 through the second dust collection duct 2632. In other words, the dust collection fan 264 is located between the dust bag compartment 215 and the noise reduction housing 262, and is communicated with the noise reduction housing 262 through the second dust collection duct 2632. It should be noted that the airflow inlet 2151 of the dust bag compartment 215 is communicated with the dust collection port 2115 of the base station through the first dust collection duct 2631, and the dust box 160 of the self-moving cleaning device 100 is also provided with an air inlet 163 and a dust inlet 166. After the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 of the base station 200, due to the dust collection airflow generated by the dust collection fan 264 in work, the debris in the dust box 160 of the self-moving cleaning device 100 can flow along with the dust collection airflow, and flow through the dust collection apparatus 261 from the dust outlet 169 of the self-moving cleaning device 100, the dust collection port 2115 on the base station 200, the first dust collection duct 2631 and the airflow inlet 2151 of the dust bag compartment 215. After the debris is collected and intercepted by the dust collection apparatus 261, the dust collection airflow flows into the dust collection fan 264 through the airflow outlet 2152 of the dust bag compartment 215, then flows into the noise reduction housing 262 from the air outlet port of the dust collection fan 264 through the second dust collection duct 2632, is exhausted to the interior of the base station housing 210 through the air exhaust port 2621 of the noise reduction housing 262, and is exhausted to the external environment through the air outlet 2119 on the base station housing 219, thereby completing the entire circulation.
[0065] The circumferential side of the dust collection port 2115 of the base station 200 is also provided with a sealing part. After the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115, the gap between the dust outlet 169 and the dust collection port 2115 can be sealed by the sealing part, which can avoid the problem of failure of dust collection caused by no negative pressure formed in the dust collection air duct arising from air leakage between the dust outlet 169 and the dust collection port 2115, and in addition, can avoid the debris leakage caused by the air leakage between the dust outlet 169 and the dust collection port 2115. Thus, it is ensured that the dust collection operation can be performed smoothly, which is beneficial for ensuring the better dust collection effect. In some examples, the sealing part may be an elastic member.
[0066] It can be understood that, as shown in FIG. 8, the interior of the accommodating cavity 211 of the base station 200 is also provided with a decorative port 21151. For example, the decorative port 21151 is formed on the sidewall of the accommodating cavity 211. The decorative port 21151 and the dust collection port 2115 are distributed on both sides of the center line of the base station 200 parallel to the vertical direction. For example, the decorative port 21151 and the dust collection port 2115 are distributed on the left and right sides of the accommodating cavity 211. An elastic part may also be arranged on the circumferential side of the decorative port 21151. In this way, when the self-moving cleaning device 100 is docked at the base station 200 and after the dust outlet 169 is butted with the dust collection port 2115, other parts of the self-moving cleaning device 100 will be abutted against the clastic part on the circumferential side of the decorative port 21151, thereby ensuring that the self-moving cleaning device 100 is reliably docked at the base station 200, and avoiding the possibility of shaking of the self-moving cleaning device 100 in the dust collection process. In addition, the provided decorative port 21151 can ensure the cleanliness and aesthetics of the appearance of the base station 200.
[0067] As shown in FIG. 13, in the above embodiment, a first filter member 2153 is arranged in the dust bag compartment 215, and the first filter member 2153 is located at the airflow outlet 2152. The provided first filter member 2153 can filter the dust collection airflow flowing into the dust collection fan 264 from the airflow outlet 2152 of the dust bag compartment 215, such that the cleanliness of the airflow flowing into the dust collection fan 264 can be improved, thereby being beneficial for improving the service life of the dust collection fan 264 and improving the reliability of the dust collection assembly 260.
[0068] In some examples, the first filter member 2153 may be a filter screen, filter cotton or other filter components. The first filter member 2153 may be fixed at the airflow outlet 2152 of the dust bag compartment 215 through at least one of a snap-fit structure, a mortise-and-tenon structure, an adhesive and a screw structure.
[0069] Typically, in order to improve the space utilization rate and the volume of the dust bag, the dust bag is usually set as large as or slightly smaller than the dust bag compartment when in design and production. However, in this way, during dust collection, blockage will be caused since the bottom of the dust bag is possibly sucked onto the airflow outlet of the dust bag compartment due to the suction force from the dust collection fan. In long-term use, under the action of the gravity of dust and the suction force from the dust collection fan, the dust bag that is originally not in contact with the airflow outlet is possibly elongated. As a result, the bottom covers the airflow outlet and causes blockage. For this, as shown in FIG. 13, in some embodiments according to the present disclosure, a plurality of supporting parts 2154 is arranged in the dust bag compartment 215, and the plurality of supporting parts 2154 is spaced apart on the circumferential side of the airflow outlet 2152 for supporting at least part of the dust collection apparatus 261. The provided supporting parts 2154 prevent the dust collection apparatus 261 from completely covering the airflow outlet 2152, thereby facilitating the flowing of the dust collection airflow, preventing the occurrence of blockage, and being beneficial for improving the dust collection efficiency.
[0070] As shown in FIG. 7, FIG. 8, FIG. 13, FIG. 14, FIG. 19 and FIG. 20, in some embodiments according to the present disclosure, the base station 200 also includes: a dust bag compartment cover 2156, and an opening of the dust bag compartment 215 on the base station housing 210 is forward. The front-and-back direction of the base station 200 is as shown in FIG. 7, that is, the opening of the dust bag compartment 215 is located in the front of the base station 200. The dust bag compartment cover 2156 is detachably connected to the base station housing 210 to shield or open the opening of the dust bag compartment 215. It can be understood that when the dust bag compartment cover 2156 shields the opening of the dust bag compartment 215, the opening of the dust bag compartment 215 can also be sealed, such that the dust bag compartment 215 becomes a closed cavity to ensure that the dust collection air duct can generate negative pressure, ensuring that the dust collection operation can be reliably performed.
[0071] In the present embodiment, with the provided dust bag compartment cover 2156, the dust bag compartment 215 can be conveniently opened or closed. For example, the dust bag compartment cover 2156 can be disassembled from the base station housing 210 to expose the opening of the dust bag compartment 215, which is convenient for the user to disassemble, assemble and replace the dust collection apparatus 261 through the opening of the dust bag compartment 215, and achieves convenient use. When the dust collection operation is required, the dust bag compartment cover 2156 is buckled at the opening of the dust bag compartment 215 to seal the dust bag compartment 215, such that the dust bag compartment 215 forms part of the dust collection air duct.
[0072] The dust bag compartment cover 2156 may be detachably connected to the base station housing 210 through at least one of a snap-fit structure, a mortise-and-tenon structure, a magnetic attraction structure and a screw structure.
[0073] In the above embodiment, the dust bag compartment cover 2156 is detachably connected to the base station housing 210 through the snap-fit assembly. Due to the simple structure and lower cost of the snap-fit assembly, compared with the base station provided with a slide-out drawer to place the dust bag in the related art, the structure of the base station 200 is simplified, which is beneficial for reducing the manufacturing cost of the base station 200. In addition, compared with the dust bag compartment cover and the base station housing which are connected by a magnetic attraction assembly in the related art, the advantage of lower cost is also achieved.
[0074] As shown in FIG. 18 and FIG. 20, in some embodiments according to the present disclosure, the snap-fit assembly connecting the dust bag compartment cover 2156 and the base station housing 210 includes a first snap-fit member 2157 and a second snap-fit member 2158 which match to each other, the first snap-fit member 2157 is located on the dust bag compartment cover 2156 and the second snap-fit member 2158 is located on the base station housing 210. Thus, by mutual cooperation between the first snap-fit member 2157 and the second snap-fit member 2158, the dust bag compartment cover 2156 may be connected onto the base station housing 210 to close the opening of the dust bag compartment 215, or the dust bag compartment cover 2156 is disassembled from the base station housing 210.
[0075] The first snap-fit member 2157 is detachably connected to the dust bag compartment cover 2156, and the first snap-fit member 2157 and the dust bag compartment cover 2156 may be disassembled and separated for maintenance respectively, which is beneficial for reducing the maintenance cost. It can be understood that in other embodiments, the first snap-fit member 2157 and the second snap-fit member 2158 may be interchanged in position. For example, the first snap-fit member is located on the base station housing 210 and the second snap-fit member is located on the dust bag compartment cover. The present disclosure takes the first snap-fit member 2157 being located on the dust bag compartment cover 2156 and the second snap-fit member 2158 being located on the base station housing 210 as an example for illustration.
[0076] Further, since the first snap-fit member 2157 and the second snap-fit member 2158 will be in contact and wear out in a disassembling and assembling process of the dust bag compartment cover 2156 and the base station housing 210, through the detachable connection between the first snap-fit member 2157 and the dust bag compartment cover 2156, the first snap-fit member 2157 that is severely worn or damaged can be replaced, which is convenient to operate. Moreover, compared with the related art in which the first snap-fit member and the dust bag compartment cover are integrally molded and the whole dust bag compartment cover is required to be replaced when the first snap-fit member is severely worn or damaged, the maintenance cost is reduced.
[0077] As shown in FIG. 13 and FIG. 18, in a specific example, the second snap-fit member 2158 and the base station housing 210 are of an integrated structure, thereby simplifying the assembling operation of the second snap-fit member 2158 and the base station housing 210, and being beneficial for improving the assembling efficiency. In addition, it is beneficial for improving the reliability of connection between the second snap-fit member 2158 and the base station housing 210, which further improves the overall reliability of the base station 200. It can be understood that, under the same conditions, the wear rate of the second snap-fit member 2158 may be lower than that of the first snap-fit member 2157, that is, the second snap-fit member 2158 with a lower wear rate in the snap-fit assembly is integrated on the base station housing 210, and the first snap-fit member 2157 with a higher wear rate is detachably connected to the dust bag compartment cover 2156, thereby facilitating the replacement of the first snap-fit member 2157 and prolonging the service life of the snap-fit assembly.
[0078] In another specific example (not shown in the figure), the second snap-fit member is detachably connected to the base station housing 210. In this way, the second snap-fit member and the base station housing 210 can be disassembled and separated for maintenance and replacement respectively, which is beneficial for reducing the maintenance cost.
[0079] As shown in FIG. 19 and FIG. 20, in some embodiments according to the present disclosure, the dust bag compartment cover 2156 is of a U-shaped structure. The dust bag compartment cover 2156 includes a front plate 21561 and side plates 21562 located on both sides of the front plate 21561. First snap-fit members 2157 are located on the side plates 21562. The base station housing 210 includes two bag chamber sidewalls 21551 located on both sides of the opening of the dust bag compartment 215 in a first direction. The first direction may be the left and right direction of the base station 200, as shown by the arrow X in FIG. 8. Second snap-fit members 2158 are located on the bag chamber sidewalls 21551 and outside the dust bag compartment 215. Thus, by buckling the dust bag compartment cover 2156 onto the outer sides of the two bag chamber sidewalls 21551 of the base station housing 210, the first snap-fit members 2157 and the second snap-fit members 2158 may cooperate with each other, such that the front plate 21561 can be used for shielding and sealing the opening of the dust bag compartment 215. The structure is simple, the design requirements of the base station 200 on compact structure and smaller size can be met, and the cost of this structure is lower.
[0080] As shown in FIG. 21 and FIG. 22, in some embodiments according to the present disclosure, each first snap-fit member 2157 includes a first connecting part 21571 and a snap-fit part 21572 which are connected to each other, and the first connecting part 21571 is connected to the side plate 21562. Thus, the whole first snap-fit member 2157 can be mounted on the dust bag compartment cover 2156 by connecting the first connecting part 21571 to the corresponding the side plate 21562. The first connecting part 21571 and the side plate 21562 may be connected by a screw. For example, the first connecting part 21571 is provided with a through hole, and the side plate 21562 is provided with a threaded hole. When the screw penetrates the through hole and is connected to the threaded hole on the side plate 21562, the first connecting part 21571 can be fixed onto the dust bag compartment cover 2156.
[0081] As shown in FIG. 13 and FIG. 18, each second snap-fit member 2158 is a clamping groove formed on the bag chamber sidewall 21551, and each snap-fit part 21572 may be accommodated in and disengaged from the clamping groove. Thus, when the snap-fit parts 21572 are accommodated in the clamping grooves, the dust bag compartment cover 2156 may be connected to the base station housing 210 to shield and seal the opening of the dust bag compartment 215. When the snap-fit parts 21572 are disengaged from the clamping grooves, the dust bag compartment cover 2156 can be separated from the base station housing 210 to open the opening of the dust bag compartment 215, which facilitates the replacement of the dust collection apparatus 261.
[0082] At least the snap-fit part 21572 of the first snap-fit member 2157 is configured as an elastic member. Providing the snap-fit part 21572 as an elastic member can ensure that the snap-fit part 21572 is smoothly and reliably accommodated in or disengaged from the clamping groove, so as to ensure that the first snap-fit member 2157 and the second snap-fit member 2158 are smoothly snap-fitted or separated. It can be understood that the first connecting part 21571 of the first snap-fit member 2157 may also be configured as an elastic member, for example, the whole first snap-fit member 2157 is configured as an elastic member, which is convenient for machining.
[0083] As shown in FIG. 20, in the above embodiment, the dust bag compartment cover 2156 includes a compartment cover body 21567 and a decorative cover 21568 located outside the compartment cover body 21567. The first snap-fit members 2157 are located between the compartment cover body 21567 and the decorative cover 21568 and connected to the compartment cover body 21567. That is, the first connecting parts 21571 of the first snap-fit members 2157 are connected to the compartment cover body 21567. Moreover, the first snap-fit member 2157 can be shielded by using the decorative cover 21568, which can further ensure the appearance aesthetics of the dust bag compartment cover 2156.
[0084] By providing an avoiding hole 21563 at the position where the compartment cover body 21567 is opposite to the snap-fit part 21572, at least part of the snap-fit part 21572 can be exposed to an interior of the dust bag compartment cover 2156 by using the avoiding hole 21563, such that the dust bag compartment cover 2156 can be snap-fitted with the second snap-fit member 2158 from the outside of the two bag compartment side plates 21562 of the base station 200 to enable the dust bag compartment cover 2156 to be connected to the base station housing 210, thereby sealing the dust bag compartment 215. In addition, due to such an arrangement, the decorative cover 21568 at the position opposite to the avoiding hole 21563 can play a role of blocking and limiting the snap-fit parts 21572, which can further improve the reliability and stability of accommodating the snap-fit parts 21572 in the clamping grooves and improve the reliability of the snap-fit between the dust bag compartment cover 2156 and the base station housing 210.
[0085] The decorative cover 21568 and the compartment cover body 21567 may be detachably connected by at least one of a screw structure, a snap-fit structure, a mortise-and-tenon structure and a hot melt adhesive, such that the decorative cover 21568 and the compartment cover body 21567 can be conveniently disassembled to replace the first snap-fit member 2157.
[0086] As shown in FIG. 18 and FIG. 20, in some embodiments according to the present disclosure, a positioning part 21565 is arranged on one side of the compartment cover body 21567 away from the decorative cover 21568, a limiting part 21552 is also arranged on the base station housing 210, and the limiting part 21552 and the positioning part 21565 are adapted to limit the movement of the dust bag compartment cover 2156 relative to the base station housing 210. Thus, by using the positioning part 21565 and the limiting part 21552, the assembling of the dust bag compartment cover 2156 and the base station housing 210 can be pre-positioned, which is beneficial for improving the accuracy of the snap-fit between the first snap-fit member 2157 and the second snap-fit member 2158, and further improving the assembling efficiency of the dust bag compartment cover 2156 and the base station housing 210. The positioning part 21565 and the limiting part 21552 may be a recess and a protrusion which are matched. For example, the positioning part 21565 is a positioning protrusion arranged on the compartment cover body 21567, and the limiting part 21552 is a limiting recess formed on the bag chamber sidewall 21551 of the base station housing 210.
[0087] In some embodiments according to the present disclosure, a sealing structure is arranged on a side of the compartment cover body 21567 away from the decorative cover 21568 and configured to seal a gap between the compartment cover body 21567 and the base station housing 210 when the dust bag compartment cover 2156 shields the opening of the dust bag compartment 215. With the provided sealing structure, the airtightness of the connection between the dust bag compartment cover 2156 and the base station housing 210 can be improved, which further ensures that the dust bag compartment 215 becomes a closed cavity and ensures the reliability of the dust collection operation. In some examples, the sealing structure may be a sealing ring, a sealing surface or other sealing structures, which is not limited by the present disclosure. The sealing structure may be mounted on the compartment cover body 21567 by at least one of an adhesive, a snap-fit structure, a mortise-and-tenon structure and a screw structure.
[0088] As shown in FIG. 21 and FIG. 22, in some embodiments according to the present disclosure, the number of the snap-fit parts 21572 is one or at least two, and the number of the snap-fit parts 21572 may be reasonably set according to the specific structure and size of the snap-fit parts 21572, so as to ensure the reliability and stability of the snap-fit between the first snap-fit member 2157 and the second snap-fit member 2158. At least two snap-fit parts 21572 are spaced apart. In this way, it can be ensured that after one snap-fit part 21572 is damaged and deformed, it will not induce the deformation of the adjacent snap-fit part 21572, and the reliability of the connection between the first snap-fit member 2157 and the second snap-fit member 2158 can still be ensured by using the undeformed snap-fit part 21572 to be snap-fitted with the second snap-fit member 2158, which can further prolong the service life of the first snap-fit member 2157.
[0089] As shown in FIG. 21, in the above embodiment, the avoiding holes 21563 are in one-to-one correspondence with the snap-fit parts 21572, and the compartment cover body 21567 is provided with retaining ribs 21564 between every two adjacent avoiding holes 21563. The provided retaining ribs 21564 play a better role in protecting every two adjacent snap-fit parts 21572, and can reduce the influence of the deformed snap-fit part 21572 on the adjacent snap-fit parts 21572, which is beneficial for prolonging the overall service life of the first snap-fit members 2157 and further improving the reliability of the first snap-fit members 2157.
[0090] In a specific example, the clamping grooves and the snap-fit parts 21572 are in one-to-one correspondence, which is beneficial for improving the reliability of the snap-fit between the first snap-fit parts 21572 and the second snap-fit parts 21572, and further improving the reliability of the snap-fit between the dust bag compartment cover 2156 and the base station housing 210.
[0091] As shown in FIG. 18, in another specific example, all the snap-fit parts 21572 correspond to one clamping groove. In this way, the machining of the clamping groove is convenient and it is beneficial for reducing the manufacturing cost of the base station housing 210.
[0092] As shown in FIG. 13, FIG. 14 and FIG. 15, in some embodiments according to the present disclosure, the base station 200 further includes the dust bag bracket 270 arranged in the dust bag compartment 215. The dust bag bracket 270 is configured to mount the dust collection apparatus 261, the dust bag bracket 270 is provided with a guide groove 271, and the guide groove 271 is configured to guide the dust collection apparatus 261 to be connected to or separated from the dust bag bracket 270. In other words, the dust collection apparatus 261 and the dust bag bracket 270 can be quickly and conveniently assembled and disassembled through the guidance of the guide groove 271 on the dust bag bracket 270, which further facilitates the disposal of the debris collected by the base station 200. The operation is convenient.
[0093] By arranging a jamming-and-pinch-prevention structure 2711 on the groove wall of the guide groove 271, occurrences where the dust collection apparatus 261 is jammed or pinched in the guide groove 271 can be reduced. With the provided jamming-and-pinch-prevention structure 2711, the dust collection apparatus 261 can be unfolded smoothly and completely. The dust collection apparatus 261 has a larger size, and the problem that the dust collection apparatus 261 is jammed in the guide groove 271 and affects the flowing of the dust collection airflow is avoided, such that the dust collection effect of the base station 200 is improved. It should be noted that the dust collection apparatus 261 includes a dust bag body, the dust bag body is made of an air-permeable yet fine-particle-filtering material, such as a non-woven fabric and a paper material, and the dust bag body is configured to accommodate the debris. As mentioned in the present disclosure, the scenario where the dust collection apparatus 261 is jammed on the groove wall of the guide groove 271 means that the dust bag body is jammed on the sidewall of the guide groove 271.
[0094] As shown in FIG. 13, FIG. 14 and FIG. 15, an opening of the guide groove 271 is consistent with the opening of the dust bag compartment 215 in direction. Thus, under the condition that the dust bag compartment cover 2156 opens the opening of the dust bag compartment 215, by the opening of the dust bag compartment 215, the dust collection apparatus 261 can be mounted on the dust bag bracket 270 through the guide groove 271 or disassembled from the dust bag bracket 270 through the guide groove 271. If the opening of the dust bag compartment 215 faces the front of the base station 200, then the opening of the guide groove 271 also faces the front of the base station 200. Thus, the user can smoothly mount the dust collection apparatus 261 on the dust bag bracket 270 or disassemble the dust collection apparatus 261 from the dust bag bracket 270 through the guide groove 271 from the front of the base station 200, and the user does not need to reorient his hand within the dust bag compartment 215, which conforms to ergonomic principles and is convenient for operation.
[0095] As shown in FIG. 15, in some embodiments according to the present disclosure, the guide groove 271 is obliquely arranged relative to the vertical direction, such as the direction from the top to the bottom of the base station 200. For example, the length direction of the guide groove 271 is obliquely arranged relative to the vertical direction, in which the length direction of the guide groove 271 is as shown by the arrow L in FIG. 15. Thus, after the dust collection apparatus 261 is mounted on the dust bag bracket 270, the dust bag body of the dust collection apparatus 261 will hang down under the action of gravity. Further, the dust bag bracket 270 may be located at the top of the dust bag compartment 215, in which the top of the dust bag compartment 215 is as shown by the arrow in FIG. 15. For example, the dust bag bracket 270 is located at one corner of the top of the dust bag compartment 215.
[0096] Since the dust bag body is made of a soft material, the dust bag body will hang down under the action of gravity in the process that the dust collection apparatus 261 is mounted on the dust bag bracket 270. As a result, the situation that the dust bag body is pinched by the lower groove wall of the guide groove 271 will occur, which will hinder the full unfolding of the dust bag body in the subsequent dust collection process. It should be noted that after the dust bag is mounted on the dust bag bracket 270, the dust bag body will be unfolded under the action of the dust collection airflow when the dust collection fan 264 works. In addition, under normal circumstances, the dust collection apparatus 261 is inserted and mounted through the front end opening of the guide groove 271, and the front end of the guide groove 271 may be understood as one surface of the guide groove 271 opposite to the opening of the dust bag compartment 215. For this, a notch structure is arranged on the front end surface of the lower groove wall of the guide groove 271, that is, the notch structure is opposite to the opening of the dust bag compartment 215 and is arranged on the lower groove wall of the guide groove 271. By using the notch structure to provide an avoid for the dust bag body, the situation that part of the dust bag body is jammed in the guide groove 271 under the action of gravity can be avoided, which is beneficial for smooth and complete unfolding of the dust bag body in the subsequent dust collection process.
[0097] The notch structure may be a triangular notch, an arc-shaped notch, or a notch with other shapes that meet the requirements. Further, the edge of the notch structure may be provided with a transition surface to play a guiding role. For example, the transition surface may be a smooth curved surface or inclined surface to ensure that the dust bag body can descend smoothly under the action of gravity without being jammed on the groove wall of the guide groove 271.
[0098] As shown in FIG. 16 and FIG. 17, in some embodiments according to the present disclosure, a hollow cavity body is arranged inside the dust bag bracket 270. The hollow cavity body includes a dust exhaust connecting port 2712 located on the bracket sidewall of the dust bag bracket 270 facing the interior of the dust bag compartment 215, and the dust exhaust connecting port 2712 is configured to be butted with the inlet of the dust collection apparatus 261. The hollow cavity body further includes a dust intake connecting port 2713 located on the bracket sidewall of the dust bag bracket 270 facing the outside of the dust bag compartment 215. The dust bag compartment 215 is provided with the airflow inlet 2151, and the dust intake connecting port 2713 is configured to be butted with the airflow inlet 2151 of the dust bag compartment 215.
[0099] In other words, the hollow cavity body of the dust bag bracket 270 may be used as part of the dust collection air duct of the base station 200. When the dust collection assembly 260 of the base station 200 works, the dust collection airflow flows into the base station 200 through the dust box 160 of the self-moving cleaning device 100, and then flows into the dust collection apparatus 261 through the airflow inlet 2151 of the dust bag compartment 215 and the hollow cavity body of the dust bag bracket 270, so as to collect and intercept the debris in the dust collection apparatus 261.
[0100] As shown in FIG. 17, the notch structure is located at the connection position between the groove wall and the dust exhaust connecting port 2712. Under normal circumstances, the dust bag body will be jammed at the connection position between the groove wall of the guide groove 271 and the dust exhaust connecting port 2712. Therefore, by arranging the notch structure at this position, the occurrence of jamming of the dust bag body can be reduced. However, under normal circumstances, the dust bag body will be jammed at the part of the bottom end of the dust exhaust connecting port 2712 when hanging down under the action of gravity. Thus, by distributing the notch structure at least at the bottom of the front end of the dust exhaust connecting port 2712, the occurrence of jamming of the dust bag body can be greatly reduced.
[0101] In some examples, one notch structure may be arranged at the connection position between the front end bottom of the dust exhaust connecting port 2712 and the lower groove wall of the guide groove 271. Or, as shown in FIG. 15, one notch structure may be arranged at the connection position between the front end bottom of the dust exhaust connecting port 2712 and the lower groove wall of the guide groove 271, and at the connection position between the front end top and the lower groove wall of the guide groove 271, respectively. The top-bottom direction in FIG. 15 is the top-bottom direction of the base station.
[0102] As shown in FIG. 14 and FIG. 16, in the above embodiment, the base station 200 further includes a sealing member 273 arranged between the bag chamber sidewall 21551 of the dust bag compartment 215 and the bracket sidewall where the dust intake connecting port 2713 is located. The sealing member 273 is used for sealing the gap between the bag chamber sidewall 21551 and the bracket sidewall. Thus, the airtightness of the connection between the bag chamber sidewall 21551 of the dust bag compartment 215 and the bracket sidewall of the dust bag bracket 270 can be improved, the problem of failure of dust collection caused by no negative pressure formed in the dust collection air duct arising from air leakage between the bag chamber sidewall 21551 and the bracket sidewall of the dust bag bracket 270 can be avoided. In addition, the problem of debris leakage from the gap between the bag chamber sidewall 21551 and the bracket sidewall can be avoided, which further ensures that the dust collection operation can be smoothly performed and is beneficial for ensuring the better dust collection effect.
[0103] The sealing member 273 may be sealing cotton, a sealing ring, a sealing strip or other sealing structures. In some examples, the sealing member 273 may be sealing foam, the scaling member 273 may be fixed onto the bracket sidewall by means of bolts and/or positioning posts, and then the dust bag bracket 270 is connected to the bag chamber sidewall 21551 to seal the gap between the bracket sidewall and the bag chamber sidewall 21551 by the sealing member 273.
[0104] As shown in FIG. 17, in some embodiments according to the present disclosure, the dust bag bracket 270 includes a sliding baffle 272 that can slide along the guide groove 271, and the sliding baffle 272 is configured to switch between a first position and a second position. In response to the sliding baffle 272 being in the first position, the sliding baffle 272 shields the dust exhaust connecting port 2712, and in response to the sliding baffle 272 being in the second position, the sliding baffle 272 exposes the dust exhaust connecting port 2712. Since the dust collection apparatus 261 is a consumable, it can be detachably mounted with the dust bag bracket 270. When the dust bag bracket 270 in the above design is not equipped with the dust collection apparatus 261, the dust exhaust connecting port 2712 can be shielded by the sliding baffle 272 to isolate the dust bag compartment 215 from the dust collection air duct. Therefore, the suction force generated by the dust collection fan 264 cannot enter the dust bag compartment 215, and the debris is prevented from entering the dust bag compartment 215 not equipped with the dust collection apparatus 261. It should be noted that, as shown in FIG. 16, the dust bag bracket 270 further includes an elastic part 274 connected to the sliding baffle 272, and the elastic part 274 is configured to endow the sliding baffle 272 with a tendency to be in the first position. When the sliding baffle 272 is not subjected to an external force, the sliding baffle 272 is in the first position under the action of the elastic part 274, such that the sliding baffle 272 shields the dust exhaust connecting port 2712.
[0105] It can be understood that the dust bag is configured to slide along an extending direction of the guide groove 271. When the dust collection apparatus 261 is inserted into the guide groove 271 and slides along the guide groove 271 to the interior of the dust bag compartment 251, the sliding baffle 272 will be pushed to slide along the extending direction of the guide groove 271, such that the dust collection apparatus 261 is mounted on the dust bag bracket 270, and the sliding baffle 272 exposes the dust exhaust connecting port 2712 to enable the opening of the dust bag to be butted with the dust exhaust connecting port 2712. After the dust bag is mounted on the dust bag bracket 270, the dust bag may be pulled in the direction towards the outside of the dust bag compartment 215, such that the dust bag can slide along the guide groove 271 and be disengaged from the guide groove 271 to achieve the disassembling of the dust bag from the dust bag bracket 270. In addition, under the action of the elastic part 274, the sliding baffle 272 may be reset to its initial position to shield the dust exhaust connecting port 2712.
[0106] As shown in FIG. 17, in some embodiments according to the present disclosure, the lower groove wall of the guide groove 271 is provided with a hollowed-out structure at the position away from the jamming-and-pinch-prevention structure 2711. That is, the lower groove wall of the guide groove 271 is provided with a hollowed-out structure in the dust bag compartment 215 at the opening away from the dust bag compartment 215. The hollowed-out structure is configured to expose part of the sliding baffle 272, and may be an opening. The bracket bottom wall of the dust bag bracket 270 is provided with a guide structure 2714 located in the dust bag compartment 215, and the guide structure 2714 is located on one side of the hollowed-out structure away from the sliding baffle 272. The provided guide structure 2714 can prevent the dust collection apparatus 261 from misaligning, jamming or protruding through the hollowed-out structure in the guide groove 271 when the dust collection apparatus 261 is inserted into the guide groove 271, such that the dust collection apparatus 261 can be smoothly abutted against the sliding baffle 272 on the dust bag bracket 270 under the guidance of the guide groove 271 and the guide structure 2714, thereby pushing the sliding baffle 272 to slide in the guide groove 271 to expose the dust exhaust connecting port 2712.
[0107] The guide structure 2714 may be a guide protrusion, and one side of the guide protrusion facing the guide groove 271 is provided with a guide inclined surface. Under the guidance of the guide inclined surface, the dust collection apparatus 261 in the guide groove 271 can smoothly slide in the guide groove 271 and can be accurately abutted against the sliding baffle 272.
[0108] In the dust box 160 of the self-moving cleaning device 100 according to the present disclosure, in a specific example, the filter part 161 is detachably connected to the dust box 160. After the dust box 160 is disassembled from the machine main body 110 of the self-moving cleaning device 100, the filter part 161 may be disassembled from the dust box 160 to clean the debris in the dust box 160 or wash the dust box through the air vent port.
[0109] In another specific example, the dust box 160 includes a top wall, a bottom wall, and a dust box sidewall. A debris storage chamber 162 has an opening. For example, an opening 1621 of the debris storage chamber is defined by the dust box sidewall, and the top wall of the dust box is arranged to be movably connected to the dust box sidewall to open or close the opening 1621 of the debris storage chamber. When the dust box 160 is disassembled from the machine main body 110 of the self-moving cleaning device 100, the dust box 160 can be cleaned, such as washing the dust box 160 or dumping out the debris in the dust box 160, or maintaining the dust box 160, as long as the opening 1621 of the debris storage chamber is opened by utilizing the top wall of the dust box. After the top wall of the dust box closes the opening 1621 of the debris storage chamber, the dust box 160 is mounted on the machine main body 110, and then the dust suction operation can be performed.
[0110] As shown in FIG. 4 and FIG. 6, in the dust box 160 according to the embodiment of the present disclosure, the dust exhaust port 164 is formed on the sidewall of the debris storage chamber 162, and the sidewall of the debris storage chamber 162 where the dust exhaust port 164 is located is obliquely arranged with respect to other sidewalls of the debris storage chamber 162 in the circumferential direction. The circumferential side of the debris storage chamber 162 may be understood as the circumferential side of the opening 1621 of the debris storage chamber. In other words, the dust exhaust port 164 is arranged on one sidewall of the circumferential side of the opening of the debris storage chamber 162, and this sidewall is obliquely arranged with respect to other sidewalls on the circumferential side of the opening of the debris storage chamber 162, such that the plane where the dust exhaust port 164 is located is obliquely arranged with respect to other sidewalls of the debris storage chamber 162 in the circumferential direction, thereby improving the smooth exhausting of the airflow in the dust box 160 through the dust exhaust port 164 and enhancing the flowing efficiency of the airflow in the dust box 160.
[0111] As shown in FIG. 3 and FIG. 6, by arranging a flow guide member 165 in the debris storage chamber 162, the airflow flowing into the air inlet 163 is guided to the dust exhaust port 164 by the flow guide member 165. For example, the dust collection airflow flowing into the air inlet 163 is guided to the dust exhaust port 164 by the flow guide member 165, which can further avoid the problem that the debris in the dust box 160 is gathered at the corner of the debris storage chamber 162 and cannot be collected. Therefore, it is beneficial for improving the thoroughness of collecting the debris in the dust box 160 to the base station 200 and improving a dust collection effect.
[0112] In the above embodiment, the flow guide member 165 is of an arc-shaped structure, and the arc-shaped flow guide member 165 has a better guiding effect on the airflow, which can further improve the smooth exhausting of the airflow in the dust box 160 through the dust exhaust port 164, and improve the flowing efficiency of the dust collection airflow in the dust box 160. In addition, the occurrence of debris gathering on the flow guide member 165 is reduced, which is beneficial for further improving the thoroughness of collecting the debris in the dust box 160 to the base station 200.
[0113] As shown in FIG. 3 and FIG. 6, a windward surface 1651 of the flow guide member 165 has a concave arc shape, and the provided concave arc shape can increase a flowing space of the dust collection airflow between the air inlet 163 and the dust exhaust port 164 to a certain extent, which is beneficial for improving the flowing smoothness of the dust collection airflow in the dust box 160. In addition, the concave arc-shaped windward surface 1651 can smoothly guide the dust collection airflow flowing into the air inlet 163 to the dust exhaust port 164, and can further guide the debris in the dust box 160 to the dust exhaust port 164 along with the dust collection airflow, which is beneficial for improving the dust collection effect.
[0114] As shown in FIG. 3 and FIG. 6, in some embodiments according to the present disclosure, a first end of the flow guide member 165 is connected to the sidewall of the debris storage chamber 162 at the dust exhaust port 164, and a second end of the flow guide member 165 extends towards a direction close to the air inlet 163 and is connected to the sidewall of the debris storage chamber 162. In other words, the flow guide member 165 also plays the role of a baffle. The inner space of the dust box 160 may be divided into two cavities which are isolated from each other by the flow guide member 165, and the air inlet 163 and the dust exhaust port 164 are located in the cavity where the windward surface 1651 of the flow guide member 165 is located. Or, in some examples, the dust box 160 may be configured to have an irregular shape, and one sidewall of the dust box 160 may be arranged as the flow guide member 165. Thus, the dust collection airflow flowing into the air inlet 163 can be smoothly guided to the dust exhaust port 164 by using the flow guide member 165, so as to avoid the problem that the debris is gathered and cannot be collected conveniently caused by the fact that the dust collection airflow flowing into the cavity or the position where the leeward surface 1652 of the flow guide member 165 is located cannot be smoothly exhausted through the dust exhaust port 164, and the thoroughness of collecting the debris in the dust box 160 to the base station 200 is greatly improved.
[0115] In addition, the windward surface 1651 of the flow guide member 165 has a concave arc shape, such that the connection positions between two end parts of the flow guide member 165 and the sidewall of the debris storage chamber 162 form larger angles, which can reduce or avoid the phenomenon of debris gathering.
[0116] As shown in FIG. 4, FIG. 5 and FIG. 6, in some embodiments according to the present disclosure, the sidewalls of the debris storage chamber 162 include a first dust box sidewall 1611, a second dust box sidewall 1612, a third dust box sidewall 1613, a fourth dust box sidewall 1614 and a fifth dust box sidewall 1615 which are connected in sequence. The first dust box sidewall 1611 and the third dust box sidewall 1613 are oppositely arranged. The second dust box sidewall 1612 and the fifth dust box sidewall 1615 are oppositely arranged. The fourth dust box sidewall 1614 is connected between the third dust box sidewall 1613 and the fifth dust box sidewall 1615 and obliquely arranged with respect to the third dust box sidewall 1613 and the fifth dust box sidewall 1615. The dust exhaust port 164 is formed on the fourth dust box sidewall 1614. Thus, it can be ensured that the fourth dust box sidewall 1614 where the dust exhaust port 164 is located is obliquely arranged with respect to the first dust box sidewall 1611, the second dust box sidewall 1612, the third dust box sidewall 1613 and the fifth dust box sidewall 1615. That is, the dust exhaust port 164 is obliquely arranged relative to the first dust box sidewall 1611, the second dust box sidewall 1612, the third dust box sidewall 1613 and the fifth dust box sidewall 1615, which is beneficial for the smooth exhausting of the dust collection airflow in the dust box 160 through the dust exhaust port 164.
[0117] An inclination angle between the fourth dust box sidewall 1614 and the third dust box sidewall 1613 is more than 90 degrees and less than 180 degrees, such that the inclination angle between the sidewall of the dust box 160 of the debris storage chamber 162 where the dust exhaust port 164 is located and the adjacent sidewall of the dust box 160 of the debris storage chamber 162 is larger, which facilitates the flowing of the dust collection airflow and can reduce the gathering of the debris at the connection position between the fourth dust box sidewall 1614 and the third dust box sidewall 1613 and at the connection position between the fourth dust box sidewall 1614 and the fifth dust box sidewall 1615.
[0118] In the above embodiment, the air inlet 163 is formed on the second dust box sidewall 1612, and the dust exhaust port 164 is formed on the fourth dust box sidewall 1614, such that the flowing of the dust collection airflow is smooth. The dust inlet 166 is formed on the first dust box sidewall 1611, and the air vent port 1601 is formed on the third dust box sidewall 1613, such that the flowing of the dust suction airflow is smooth.
[0119] As shown in FIG. 6, one end of the flow guide member 165 is adjacent to one side of the dust exhaust port 164, and is configured at an angle about 90 degrees to the plane where the dust exhaust port 164 is located, such that the dust collection airflow is exhausted from the dust exhaust port 164 at an approximately vertical angle under the guidance of the flow guide member 165.
[0120] As shown in FIG. 3, in some embodiments according to the present disclosure, the dust exhaust port 164 and the dust outlet 169 are communicated in the machine main body 110 of the self-moving cleaning device 100 through a dust exhaust channel 168. The dust exhaust channel 168 is configured at an angle about 90 degrees to the plane where the dust exhaust port 164 is located. That is, an extending direction of the flow guide member 165 is approximately parallel to an extending direction of the dust exhaust channel 168. Thus, the dust collection airflow in the dust box 160 can smoothly flow into the dust exhaust channel 168 under the guidance of the flow guide member 165, which further reduces the situation that the debris in the dust box 160 is gathered or blocked at the connection position between the dust exhaust port 164 and the dust exhaust channel 168, and is beneficial for improving the thoroughness in collecting the debris in the dust box 160 to the base station 200 and improving the dust collection effect.
[0121] As shown in FIG. 2, the wet cleaning system of the self-moving cleaning device 100 according to the present disclosure may include a cleaning assembly, a water supply mechanism, a liquid storage tank, and the like. The cleaning assembly may be arranged below the liquid storage tank, and a cleaning liquid in the liquid storage tank is transmitted to the cleaning assembly through the water supply mechanism, such that the cleaning assembly 180 can perform wet cleaning on a plane to be cleaned. In other embodiments of the present disclosure, the cleaning liquid in the liquid storage tank may also be directly sprayed on the plane to be cleaned, and the cleaning assembly can uniformly spread the cleaning liquid, thereby cleaning the plane. It can be understood that the self-moving cleaning device 100 is provided with a water injection port communicated with the liquid storage tank, and the liquid outside the self-moving cleaning device 100 can be replenished into the liquid storage tank by using the water injection port, so as to achieve a water replenishment operation for the liquid storage tank.
[0122] The cleaning assembly 180 according to the embodiment of the present disclosure includes a motion mechanism and a cleaning element 183 which are arranged on the machine main body 110. That is, the whole cleaning assembly 180 may be mounted on the machine main body 110 through the motion mechanism, and the cleaning assembly 180 moves with the movement of the machine main body 110 to achieve a mopping function. The motion mechanism is used for driving the cleaning element 183 to perform operations, such as lifting and lowering of the cleaning element 183 and also the rotation of the cleaning element 183. Thus, the lifting and rotating operations of the cleaning element 183 can be achieved through the motion mechanism according to the demands as to whether the cleaning element 183 needs to be in contact with the surface to be cleaned, so as to meet different functional requirements of the cleaning element 183. That is, the implementation of differentiated strategies for the cleaning element 183 can be achieved. Therefore, the cleaning performance of the self-moving cleaning device, the cleaning efficiency and use experience are improved.
[0123] As shown in FIG. 2, the cleaning element 183 is located at the rear of the dry cleaning system 151 in an advancing direction of the self-moving cleaning device 100, and the cleaning element 183 may be usually a water-absorbing flexible substance such as fabric and sponge. In this solution, the cleaning element 183 may be at least one rotating turntable, the water in the liquid storage tank of the self-moving robot is guided to the cleaning element 183, and the wetted cleaning element 183 removes the stains on the ground through rotational motion.
[0124] As shown in FIG. 23 and FIG. 24, in some embodiments according to the present disclosure, the base station 200 further includes a washing disk 220. The washing disk 220 is arranged on the bottom wall of the accommodating cavity 211, and is used for interfering with the cleaning element 183 of the self-moving cleaning device 100 to remove soiling on the cleaning element 183. Thus, when the self-moving cleaning device 100 is docked at the accommodating cavity 211 of the base station 200, the washing disk 220 can be used for implementing a washing operation on the cleaning element 183, such that the dirty cleaning element 183 is changed into a clean one for mopping the floor next time.
[0125] As shown in FIG. 23, in some embodiments according to the present disclosure, the washing disk 220 is detachably connected to the base station 200, such that the washing disk 220 can be disassembled from the base station 200 as a whole and washed, which is beneficial for improving the thoroughness of washing the washing disk 220. This avoids potential unpleasant odor generation caused by soiling remaining on the washing disk 220 for a long time arising from incomplete or inconvenient washing of the washing disk 220, thereby being beneficial for improving the washing experience of the washing disk 220 and improving usc satisfaction of the user. In addition, the washing disk 220 is detachably connected to the base station 200, which is beneficial for improving the maintenance efficiency.
[0126] As shown in FIG. 23, the washing disk 220 includes a cleaning cavity 2211 and a washing part 222 arranged inside the cleaning cavity 2211. The washing part 222 is used for interfering with the cleaning element 183 of the self-moving cleaning device 100 to remove soiling on the cleaning element 183, thereby implementing the cleaning operation on the cleaning element 183. For example, in the case where the cleaning element 183 is a mopping disk, a washing operation is implemented on the mopping disk by the interference between the mopping disk and the washing part 222 in the cleaning cavity 2211. Since the cleaning cavity 2211 is used for accommodating soiling, the washing part 222 can remove the soiling on the cleaning element 183 and then the soiling is collected in the cleaning cavity 2211.
[0127] The washing disk 220 is configured to be detachably connected to the base station 200, such that the washing disk 220 as a whole can be detachably connected to the base station 200. Thus, the user can mount the washing disk 220 on the base station 200 or disassemble the washing disk 220 from the base station 200 as required. For example, the user can disassemble the entire washing disk 220 from the base station 200, it is convenient to wash the washing disk 220, which improves the convenience in washing the washing disk 220, improves the thoroughness in washing the washing disk 220, prevents the soiling from being gathered or left in the cleaning cavity 2211 for a long time to generate unpleasant odors, thereby being beneficial for improving the use satisfaction of the user.
[0128] As shown in FIG. 23, in some embodiments according to the present disclosure, a sewage sump 2212 located inside the cleaning cavity 2211 is arranged on the bottom wall of the cleaning cavity 2211, and the bottom of the sewage sump 2212 may be lower than the upper surface of the bottom wall of the cleaning cavity 2211, such that after the washing part 222 removes the soiling on the cleaning element 183, the soiling will be gathered in the sewage sump 2212 under the action of gravity. The washing disk 220 further includes a sewage pipe 223. The sewage pipe 223 is arranged on the sewage disk 220. A first end of the sewage pipe 223 is communicated with the sewage sump 2212, and a second end of the sewage pipe 223 extends to the outside of the cleaning cavity 2211. Thus, the sewage pipe 223 can be used for discharging the soiling in the sewage sump 2212, and then the soiling in the cleaning cavity 2211 can be discharged in time, such that the cleaning cavity 2211 can continue to accommodate soiling to achieve continuous washing of the cleaning element 183, which is beneficial for improving the washing effect. In addition, it is possible to avoid secondary contamination caused by overflow of the soiling in the cleaning cavity 2211 that is not discharged in time, which is beneficial for improving the use satisfaction of the user.
[0129] In the above embodiment, the base station 200 includes a sewage tank 214, and the second end of the sewage pipe 223 is communicated with the sewage tank 214, such that the soiling can be collected in the sewage tank 214. It can be understood that a water pump may be arranged on the duct for communicating the sewage pipe 223 to the sewage tank 214 to achieve the collection of sewage.
[0130] As shown in FIG. 8 and FIG. 23, in some embodiments according to the present disclosure, the washing disk 220 further includes water guide parts 224. The water guide parts 224 are arranged on the inner bottom wall of the cleaning cavity 2211 and protrude out of the surface of the cleaning cavity 2211. That is, each water guide part 224 may be understood as a water guide rib. Water guide grooves 2241 are formed at the top of the water guide part 224, communicated with a water outlet 2112 on the base station 200, used for accommodating the cleaning liquid, and can interference with the cleaning elements 183. Thus, the cleaning liquid flows into the water guide grooves 2241 from the water outlet 2112 of the base. When the cleaning elements 183 interfere with the water guide grooves 2241, the cleaning elements 183 can be wetted by the cleaning liquid in the water guide grooves 2241, and then the cleaning elements 183 interfere with the washing part, such that the washing of the cleaning elements 183 can be achieved. Such an arrangement is beneficial for improving the cleaning effect of the cleaning elements 183. The water guide parts 224 protrude out of the surface of the cleaning cavity 2211, such that the water guide grooves 2241 on the water guide parts 224 can reliably interfere with the cleaning elements 183 to ensure that the cleaning elements 183 can be smoothly wetted by the water in the water guide grooves 2241.
[0131] As shown in FIG. 24, each water guide part 224 is provided with a liquid discharging port 2242 communicated with the water guide groove 2241. After the cleaning liquid enters the water guide groove 2241 of the water guide part 224, since the cleaning liquid in the water guide groove 2241 cannot be completely dipped by the cleaning element 183 of the self-moving cleaning device 100 and there may be case that the cleaning liquid remains in the water guide groove 2241. By forming the liquid discharging port 2242 communicated with the water guide groove 2241 on the water guide part 224, the remaining cleaning liquid in the water guide groove 2241 can be discharged from the liquid discharging port 2242, which can avoid unpleasant odors produced by the liquid remaining in the water guide groove 2241 for a long time, thereby being further beneficial for improving the cleanliness of the water guide groove 2241. It can be understood that the water guide part 224 and the washing part 222 may also be washed in the process that the washing disk 220 is taken down from the base station 200 for washing.
[0132] As shown in FIG. 7 and FIG. 8, a clean water tank 213 is located above the accommodating cavity 211 and configured to accommodate cleaning liquid. Water outlets 2112 are communicated with the clean water tank 213, and the cleaning liquid in the clean water tank 213 can be input into the water guide grooves 2241 through the water outlets 2112. The water outlets 2112 may be located at the top of the accommodating cavity 211, and the water outlets 2112 directly face the water guide grooves 2241 of the water guide parts 224. In this way, the opening and closing of the water outlets 2112 are controlled by valves and other components, such that the cleaning liquid in the clean water tank 213 can be input into the water guide grooves 2241 under the action of gravity. It can be understood that the water outlets 2112 may also be located at the sidewalls of the container cavity, and the water outlets 2112 and the water guide grooves 2241 are communicated through a duct, such that the cleaning liquid in the clean water tank can flow into the water guide grooves 2241.
