[0039] The exemplary embodiments according to the present disclosure will now be described in more detail with reference to the accompanying drawings. However, these exemplary 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 exemplary embodiments to those skilled in the art.
[0040] As shown in FIGS. 1 to 16, 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.
[0041] Further, as shown in FIGS. 1 and 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 a cleaning operation in a certain region to be cleaned without user operations. 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.
[0042] As shown in FIG. 1, the machine main body 110 includes a forward portion 111 and a rearward 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.
[0043] 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 both arranged on a buffer 122 of the forward portion 111 of the machine main body 110, a cliff sensor arranged at a lower portion of the machine main body 110, and a magnetometer, an accelerometer, a gyroscope and an odograph and other sensing apparatuses arranged inside the machine main body 110, for providing various position information and motion status information of a machine to the control module. The position determining apparatus 121 includes, but is not limited to, a camera, a laser distance sensor (LDS, Laser Distance Sensor in full name).
[0044] 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 in the process of cleaning, the buffer 122 detects one or more events in a travel path of the self-moving cleaning device 100 via a sensor system arranged thereon, for example, an infrared sensor. The self-moving cleaning device 100 may control, based on the events (e.g., an obstacle and a wall) detected by the buffer 122, the driving wheel module 141 to enable the self-moving cleaning device 100 to respond to the event, for example, by moving away from the obstacle.
[0045] The control module is arranged on a main circuit board inside the machine main body 110 and includes a computing processor, such as a central processing unit and an application processor, in communication with a non-transitory memory, such as a hard disk, a flash memory and a random-access memory. The application processor is configured to draw a simultaneous map of an environment where the self-moving cleaning device 100 is located based on obstacle information fed back by the laser distance sensor by use of a positioning algorithm, for example, simultaneous localization and mapping (SLAM, Simultaneous Localization And Mapping in full name). 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 odograph, and other sensing apparatuses arranged on the buffer 122, a comprehensive judgment may be made on a current working status and a current position of the self-moving cleaning device 100, as well as a 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, having a full dust box, being picked up, etc. For different cases, specific next action strategies will be given, such that the operation of the self-moving cleaning device 100 is more in line with the requirements of an owner, thereby providing better user experience.
[0046] 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, such as components of x, y and . The driving system 140 includes a driving wheel module 141, and the driving wheel module 141 may control both of a left wheel and a right wheel simultaneously. In order to control the movement of the machine more accurately, the driving wheel module 141 preferably includes a left driving wheel module and a right driving wheel module, which are arranged along a transverse axis defined by the machine main body 110. In order to enable the self-moving cleaning device 100 to move more stably or have a better movement ability on the ground, the self-moving cleaning device 100 may include one or more driven wheels 142, and the driven wheels 142 include but are 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 odograph, and a circuit for measuring a driving current. A driving wheel may be provided with an offset drop suspension system, which is fastened movably to (e.g., attached rotatably to) the machine main body 110, and receives 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 cleaning elements 183 of the self-moving cleaning device 100 are also in contact with the ground with certain pressure.
[0047] The energy system includes a rechargeable battery, such as a nickel-metal hydride battery and a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detecting 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 on one side or below the machine body for charging.
[0048] The human-machine interaction system 170 includes buttons on a panel of the main unit for a user to select functions, and may further include a display screen and/or an indicator light and/or a horn. The display screen, the indicator light or the horn presents a current status or function options of the self-moving cleaning device to the user. The human-machine interaction system may further include a mobile phone client program. For a route navigation type self-moving cleaning device 100, a mobile phone client may show the user a map of the environment where the device is located, as well as a position of the device, thereby providing the user with richer and more user-friendly function items.
[0049] As shown in FIG. 2, the cleaning system 150 includes a dry cleaning system 151, i.e., the self-moving cleaning device 100 may be a sweeper, or the cleaning system 150 includes a wet cleaning system and a dry cleaning system 151, i.e., the self-moving cleaning device 100 may be a sweeping and mopping integrated machine. The wet cleaning system includes at least one cleaning element 183, and the cleaning element 183 may be a mopping disk or other wet cleaning members.
[0050] 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 having a 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 after that, the debris is 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.
[0051] The dust box 160 according to the embodiments of the present disclosure is detachably connected to the machine main body 110 of the self-moving cleaning device 100, such that the dust box 160 can be detached from the machine main body 110 of the self-moving cleaning device 100 for cleaning or maintenance, and the dust box 160 can be conveniently and quickly mounted on the machine main body 110 for a dust suction operation, which is simple and easy to operate and convenient to use.
[0052] As shown in FIGS. 3, 4, 5 and 6, the dust box 160 of the self-moving cleaning device 100 according to the embodiments of the present disclosure is provided with a debris storage chamber 162, and an air inlet 163 and a dust exhaust port 164 that 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 that are communicated with the debris storage chamber 162. The dust inlet 166 is communicated with a 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 filtering part 161 is arranged at the air vent port 1601. A suction airflow generated by operation of the dust suction fan can suck debris on a 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 filtering part 161 at the air vent port 1601, the dust suction airflow is discharged from the air vent port 1601 through the dust suction fan. Therefore, the debris can be collected in the dust box 160, and the provided filtering part 161 can prevent the debris inside the dust box 160 from entering the dust suction fan, which in turn is conducive to prolonging the service life of the dust suction fan.
[0053] 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.
[0054] 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. In the process of cleaning up impurities inside the dust box 160, i.e., during the operation of performing dust collection on the self-moving cleaning device 100 by using 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 an airflow generated inside the dust box 160 can take away the impurities more easily.
[0055] As shown in FIGS. 6 and 7, the base station 200 according to the present disclosure further includes a base station housing 210, 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. Specifically, 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 accommodation cavity 211, and the dust collection port 2115 is located inside the accommodating cavity 211. Specifically, the dust collection port 2115 may be located on a side wall of the accommodating cavity 211.
[0056] As shown in FIG. 8, the dust collection assembly 260 of the base station 200 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 that are arranged inside the base station housing 210. The dust collection apparatus 261 is arranged inside the dust bag compartment 215. The noise reduction housing 262 is provided with an air exhaust port 2621. The dust collection duct 263 is communicated with the dust collection port 2115, the dust bag compartment 215 and the noise reduction housing 262 to form a dust collection air duct. The dust collection fan 264 is arranged on the dust collection air duct. A dust collection airflow generated by the dust collection fan 264 sucks the debris inside the dust box 160 of the self-moving cleaning device 100 through the dust collection port 2115, and after the debris is collected and intercepted by the dust collection apparatus 261, the dust collection airflow is discharged from the air exhaust port 2621. Since the airflow generated by operation of the dust collection fan 264 is discharged from the air exhaust port 2621 on the noise reduction housing 262, the noise reduction housing 262 can reduce noise of the airflow flowing therethrough. Therefore, the airflow in the dust collection air duct is discharged after being noise-reduced by the noise reduction housing 262, thereby greatly reducing aerodynamic noise of the dust collection fan 264, reducing working noise of the fan and improving the comfort of the user. The dust collection apparatus 261 may be a dust bag or other components that meet requirements.
[0057] Specifically, as shown in FIG. 8, the dust collection duct 263 includes a first dust collection duct 2631 and a second dust collection duct 2632. The first dust collection pipe 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. In the case where the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 of the base station 200, the dust collection airflow generated by the dust collection fan 264 flows through the dust box 160 of the self-moving cleaning device 100, the dust exhaust channel 168, the dust outlet 169, the dust collection port 2115, the first dust collection duct 2631, and flows into the dust bag 216 inside 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 noise reduction housing 262 from the dust bag compartment 215 through the dust collection fan 264 and the second dust collection duct 2162, and is discharged into the base station housing 210 through the air exhaust port 2621 of the noise reduction housing 262. The noise reduction housing 262 is utilized to perform noise reduction on the airflow flowing therethrough, so as to achieve the purpose of reducing the working noise of the dust collection fan 264 and improve the comfort of the user.
[0058] In some possible embodiments according to the present disclosure, as shown in FIGS. 9 and 13, 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. That is, after being discharged 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 discharged to an external environment through the air outlet 2119 formed in the base station housing 210. Since the air exhaust port 2621 is not opposite to the air outlet 2119, a propagation channel of the dust collection airflow between the air exhaust port 2621 and the air outlet 2119 is a bent channel, i.e., working noise of the dust collection fan 264 needs to be discharged 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 blocking role in outward propagation of sound and can enhance friction and dissipation of sound waves, the purpose of noise reduction is once again achieved when the dust collection airflow is discharged to the external environment through the air exhaust port 2621 and the air outlet 2119, which reduces the impact of noise on the user and in turn is conductive to improving the use comfort of the user.
[0059] As shown in FIGS. 10 and 11, in some possible 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, an air intake port of the dust collection fan 264 is connected to the airflow outlet 2152, and an air vent 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, as shown in FIG. 8, 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. As shown in FIG. 5, the dust box 160 of the self-moving cleaning device 100 is also provided with an air inlet 163 and a dust inlet 166. As shown in FIG. 3, when the dust outlet 169 of the self-moving cleaning device 100 is butted with the dust collection port 2115 of the base station 200, the dust collection airflow generated by the operation of the dust collection fan 264 can cause the debris in the dust box 160 of the self-moving cleaning device 100 to flow with the dust collection airflow and to 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 from the airflow outlet 2152 of the dust bag compartment 215, and then flows into the noise reduction housing 262 from the air discharge port of the dust collection fan 264 through the second dust collection duct 2632, is discharged to the interior of the base station housing 210 through the air exhaust port 2621 of the noise reduction housing 262, and is discharged to the external environment from the air outlet 2119 on the base station housing 219 to achieve the whole cycle.
[0060] As shown in FIGS. 10, 11 and 12, the dust bag compartment 215 on the base station housing 210 opens forward. The front of the base station 200 is as shown in FIG. 6. As shown in FIGS. 6, 7 and 13, the base station 200 further includes a dust bag compartment cover 2156, and the dust bag compartment cover 2156 is detachably connected to the base station housing 210 by means of a snap-fit assembly to uncover or cover the opening of the dust bag compartment 215. It can be understood that when the dust bag compartment cover 2156 covers the opening of the dust bag compartment 215, the opening of the dust bag compartment 215 can also be scaled, such that the dust bag compartment 215 becomes a closed cavity to ensure that negative pressure can be produced in the dust collection air duct and ensure that the dust collection operation can be reliably performed. It is convenient to replace the dust collection apparatus 261 in the dust bag compartment 215 when the dust bag compartment cover 2156 uncovers the opening of the dust bag compartment 215. As shown in FIGS. 10 and 11, the base station 200 further includes a dust bag support 270 arranged inside the dust bag compartment 215, and the dust collection apparatus 261 is mounted inside the dust bag compartment 215 through the dust bag support 270.
[0061] In this embodiment, the dust bag compartment cover 2156 is detachably connected to the base station housing 210 by means of the snap-fit assembly. The snap-fit assembly is simple in structure and lower in cost, which, compared with the related art in which a base station is provided with a pull-out drawer for placing a dust bag, simplifies the structure of the base station 200 and is conductive to reducing the manufacturing cost of the base station 200, and compared with the related art in which the dust bag compartment cover and the base station housing are connected by a magnetic attraction assembly, also has the advantage of lower cost.
[0062] As shown in FIGS. 12 and 14, in some possible embodiments according to the present disclosure, the snap-fit assembly that connects the dust bag compartment cover 2156 to the base station housing 210 includes a first snap-fit member 2157 and a second snap-fit member 2158 that match 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, through the cooperation between the first snap-fit member 2157 and the second snap-fit member 2158, the dust bag compartment cover 2156 can be connected to the base station housing 210 to close the opening of the dust bag compartment 215, or to detach the dust bag compartment cover 2156 from the base station housing 210.
[0063] The first snap-fit member 2157 is detachably connected to the dust bag compartment cover 2156. Thus, the first snap-fit member 2157 and the dust bag compartment cover 2156 can be disassembled and separated for respective maintenance, which is conductive to 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 interchangeably positioned. For example, the first snap-fit member is located on the base station body and the second snap-fit member is located on the dust bag compartment cover. The present disclosure is illustrated by taking 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.
[0064] Further, since the first snap-fit member 2157 and the second snap-fit member 2158 may contact and wear out during disassembly and assembly of the dust bag compartment cover 2156 and the base station housing 210, by detachably connecting the first snap-fit member 2157 to 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. In addition, compared with the related art in which the whole dust bag compartment cover needs to be replaced when the first snap-fit member 2157 is severely worn or damaged because the first snap-fit member and the dust bag compartment cover are integrally molded, the maintenance cost is reduced.
[0065] As shown in FIG. 12, in a specific example, the second snap-fit member 2158 and the base station housing 210 are of an integrated structure. In this way, the operation of assembling the second snap-fit member 2158 and the base station housing 210 is simplified, such that it is conductive to improving the assembly efficiency, and in addition, is conductive to improving the reliability of connection between the second snap-fit member 2158 and the base station housing 210, thereby improving 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 can be lower than that of the first snap-fit member 2157, i.e., in the snap-fit assembly, the second snap-fit member 2158 with a low wear rate is integrated on the base station housing 210, and the first snap-fit member 2157 with a high wear rate is detachably connected to the dust bag compartment cover 2156, thereby facilitating the change of the first snap-fit member 2157, and prolonging the service life of the snap-fit assembly.
[0066] In another specific example (not shown), the second snap-fit member is detachably connected to the base station housing 210, such that the second snap-fit member and the base station housing 210 can be disassembled and separated for respective maintenance and replacement, which is conductive to reducing the maintenance cost.
[0067] As shown in FIGS. 13 and 14, in some possible 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 two 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 side walls 21551 located on two sides of the opening of the dust bag compartment 215 in a first direction. The first direction may be a left-and-right direction of the base station 200, as shown by an arrow X in FIG. 7. Second snap-fit members 2158 are located on the bag chamber side walls 21551 and outside the dust bag compartment 215. Therefore, by snapping the dust bag compartment cover 2156 onto outer sides of the two bag chamber side walls 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 to cover and seal the opening of the dust bag compartment 215 using the front plate 21561. This structure is simple, can meet the design requirements of the base station 200 for a compact structure and a smaller size, and is lower in structural cost.
[0068] As shown in FIGS. 15 and 16, in some possible embodiments according to the present disclosure, each first snap-fit member 2157 includes a first connecting part 21571 and a snap-fit part 21572 connected to each other, and the first connecting part 21571 is connected to the side plate 21562, such that 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 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, the side plate 21562 is provided with a threaded hole, and the first connecting part 21571 may be fixed to the dust bag compartment cover 2156 when the screw passes through the through hole to be connected to the threaded hole in the side plate 21562.
[0069] As shown in FIG. 12, each second snap-fit member 2158 is a clamping groove formed in the bag chamber side wall 21551, and each snap-fit part 21572 is receivable in and detachable from the clamping groove. Therefore, when the snap-fit parts 21572 are received in the clamping grooves, the dust bag compartment cover 2156 may be connected to the base station housing 210 to cover and seal the opening of the dust bag compartment 215. When the snap-fit parts 21572 are detached from the clamping groove, the dust bag compartment cover 2156 can be separated from the base station housing 210 to uncover the opening of the dust bag compartment 215, thereby facilitating replacement of the dust collection apparatus 261.
[0070] At least the snap-fit part 21572 of the first snap-fit member 2157 is provided 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 received in or detached from the clamping groove, so as to ensure that the first snap-fit member 2157 and the second snap-fit member 2158 are smoothly engaged or disengaged. It can be understood that the first connecting part 21571 of the first snap-fit member 2157 may also be provided as an elastic member, for example, the whole first snap-fit member 2157 may be provided as an elastic member, to facilitate processing.
[0071] As shown in FIG. 14, in the above embodiments, 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. In addition, the first snap-fit members 2157 can be covered using the decorative cover 21568, which in turn can ensure the aesthetic appearance of the dust bag compartment cover 2156.
[0072] By providing an avoidance hole 21563 at a position of the compartment cover body 21567 opposite to each 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 avoidance hole 21563, such that the dust bag compartment cover 2156 can be in snap-fit with the second snap-fit members 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, with this arrangement, the decorative cover 21568 at the position opposite to the avoidance holes 21563 can play a role of blocking and limiting the snap-fit parts 21572, which in turn can improve the reliability and the stability of the snap-fit parts 21572 being received in the clamping grooves and improve the reliability of snap-fit between the dust bag compartment cover 2156 and the base station housing 210.
[0073] The decorative cover 21568 and the compartment cover body 21567 may be detachably connected by means of at least one of a screw structure, a snap-fit structure, a mortise-and-tenon structure and a hot melt adhesive, to facilitate disassembly of the decorative cover 21568 and the compartment cover body 21567 to replace the first snap-fit member 2157.
[0074] As shown in FIGS. 14 and 15, in some possible embodiments according to the present disclosure, a positioning part 21565 is arranged on a side of the compartment cover body 21567 away from the decorative cover 21568, the base station housing 210 is also provided with a limiting part 21552, 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. Therefore, by using the positioning part 21565 and the limiting part 21552, the assembly of the dust bag compartment cover 2156 and the base station housing 210 can be pre-positioned, which is conductive to improving the accuracy of snap-fit between the first snap-fit member 2157 and the second snap-fit member 2158, and in turn improves the assembly 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 that match each other. 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 in the bag chamber side wall 21551 of the base station housing 210.
[0075] In some possible 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 covers the opening of the dust bag compartment 215. The arrangement of the sealing structure can improve the airtightness of connection between the dust bag compartment cover 2156 and the base station housing 210, which in turn ensures that the dust bag compartment 215 becomes a closed cavity and ensures the reliability of the dust collection operation. Specifically, the scaling structure may be a sealing ring, a sealing surface or other sealing structures, which is not specifically limited in the present disclosure. The sealing structure may be mounted on the compartment cover body 21567 by means of at least one of an adhesive, a snap-fit structure, a tenon-and-mortise structure and a screw structure.
[0076] As shown in FIGS. 15 and 16, in some possible embodiments according to the present disclosure, the number of the snap-fit parts 21572 is one or at least two. The number of the snap-fit parts 21572 may be reasonably set according to the specific structures and sizes of the snap-fit parts 21572, to ensure the reliability and stability of snap-fit between the first snap-fit members 2157 and the second snap-fit members 2158. At least two snap-fit parts 21572 are spaced apart; and this configuration can ensure that if one snap-fit part 21572 is damaged and deformed, it will not induce the deformation of the adjacent snap-fit part 21572. The snap-fit with the second snap-fit member 2158 by using the un-deformed snap-fit part 21572 can still ensure the reliability of connection between the first snap-fit member 2157 and the second snap-fit member 2158, which in turn can prolong the service life of the first snap-fit member 2157.
[0077] As shown in FIGS. 15 and 16, in the above embodiments, the avoidance holes 21563 are in one-to-one correspondence with the snap-fit parts 21572, and the compartment cover body 21567 is provided with a retaining rib 21564 between every two adjacent avoidance holes 21563. The provided retaining ribs 21564 plays a good role in protecting the two adjacent snap-fit parts 21572, and can reduce the impact of the deformed snap-fit part 21572 on the adjacent snap-fit part 21572, which is conductive to prolonging the overall service life of the first snap-fit members 2157 and in turn improves the reliability of the first snap-fit members 2157.
[0078] In a specific example, the clamping grooves and the snap-fit parts 21572 are in one-to-one correspondence, which is conductive to improving the reliability of snap-fit between the first snap-fit parts 21572 and the second snap-fit parts 21572, and in turn improves the reliability of snap-fit between the dust bag compartment cover 2156 and the base station housing 210.
[0079] As shown in FIG. 12, in another specific example, all the snap-fit parts 21572 correspond to one clamping groove, which facilitates machining of the clamping groove and is conductive to reducing the manufacturing cost of the base station housing 210.
[0080] As shown in FIG. 10, in the above embodiments, a first filtering member 2153 is arranged inside the dust bag compartment 215, and the first filtering member 2153 is located at the airflow outlet 2152. The provided first filtering 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 conductive to prolonging the service life of the dust collection fan 264 and improving the reliability of the dust collection assembly 260.
[0081] Specifically, the first filtering member 2153 may be a filter screen, filter cotton or other filtering components, and the first filtering member 2153 may be fixed at the airflow outlet 2152 of the dust bag compartment 215 by means of at least one of a snap-fit structure, a mortise-and-tenon structure, an adhesive and a screw structure.
[0082] 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 in design and production. However, in this way, during dust collection, the bottom of the dust bag may be sucked onto the airflow outlet of the dust bag compartment due to suction from the dust collection fan, resulting in blockage. In long-term use, under the action of the gravity of dust and suction from the dust collection fan, the dust bag that is originally not in contact with the airflow outlet may also be elongated. As a result, the bottom of the dust bag covers the airflow outlet to cause blockage. Therefore, as shown in FIG. 10, in some possible embodiments according to the present disclosure, a plurality of supporting parts 2154 is arranged inside the dust bag compartment 215, and spaced apart around the circumstance 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 flow of the dust collection airflow, preventing blockage and being conductive to improving the dust collection efficiency.
[0083] As shown in FIG. 2, in the self-moving cleaning device according to the present disclosure, the wet cleaning system 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 inside the liquid storage tank is transmitted to the cleaning assembly by means of the water supply mechanism, such that the cleaning assembly can perform wet cleaning on a plane to be cleaned. In other embodiments of the present disclosure, the cleaning liquid inside the liquid storage tank may also be directly sprayed onto the plane to be cleaned, and the cleaning assembly uniformly spreads the cleaning liquid, thereby cleaning the plane. It can be understood that the self-moving cleaning device 100 is provided with a water filling port communicated with the liquid storage tank, and the liquid storage tank can be replenished with a liquid outside the self-moving cleaning device 100 by means of the water filling port, so as to achieve a replenishment operation on the liquid storage tank with water.
[0084] The cleaning assembly according to an embodiment of the present disclosure includes a movement mechanism and a cleaning element 183 that are arranged on the machine main body 110, i.e., the whole cleaning assembly may be mounted on the machine main body 110 by means of the movement mechanism, and the cleaning assembly moves with the movement of the machine main body 110 to achieve a mopping function. The movement mechanism is configured to drive 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. Therefore, according to the demand as to whether the cleaning element 183 is in contact with a surface to be cleaned, lifting, lowering and rotating operations of the cleaning element 183 can be achieved through the movement mechanism 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-cleaning device, the cleaning efficiency and the use experience are improved.
[0085] 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 typically be a water-absorbing flexible substance such as a fabric and sponge. In this solution, the cleaning element 183 may be at least one rotating turntable, and water in a liquid storage tank of a self-moving robot is guided to the cleaning element 183, and the wetted cleaning element 183 removes stains on the ground through rotational movement.
[0086] The present disclosure has been explained through the above embodiments, but it should be understood that the above embodiments are merely for exemplary and illustrative purposes, and are not intended to limit the present disclosure to the scope of the described embodiments. In addition, it can be understood by those skilled in the art that the present disclosure is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the present disclosure, all of which fall within the scope of the protection of the present disclosure. The scope of protection of the present disclosure is defined by the appended claims and equivalent scopes thereof.
