DESCRIPTION OF EMBODIMENTS

(20) The following explains the implementations of the application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through different specific implementations, and the details in this specification can be modified or changed based on different perspectives and applications without departing from the spirit of the present application.

(21) It should be noted that the drawings provided in the present embodiments only illustrate the basic concept of the present application in a schematic way. The drawings only show the components related to the present application, and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed randomly, and the layout of the components may be more complicated.

(22) At present, more and more users begin to use cleaning device for home cleaning, especially the popular floor washing machine. For example, the floor washing machine has a device body and a floor brush assembly connected with the device body. When cleaning, the user only needs to hold and push a handle provided on the device body. Generally, the floor washing machine also includes a clean water tank and a sewage tank. In a cleaning process, a liquid separator in the floor brush assembly will guide the water flow from the clean water tank to spray water to clean a rolling brush body in the floor brush assembly, so that the rolling brush body can clean a surface to be cleaned, and the surface to be cleaned will be wet by the rolling brush body, as so to achieve a better stains cleaning.

(23) During the cleaning process of the rolling brush, it will suck the dirt into the sewage tank through a rotation and a suction of the device body, so it can be seen that the rolling brush body is actually a very important cleaning component in the floor washing machine, and it can clean the surface to be cleaned through high-speed rotation. It is conceivable that after a long period of cleaning, the rolling brush will be greatly worn, and the worn rolling brush will affect the subsequent cleaning effect.

(24) Therefore, the rolling brush body needs to be replaced in time after being used for a period of time, so in fact, the rolling brush body is already a consumable, but the replacement of the rolling brush body now is more than just a replacement of the rolling brush body itself, the connection assembly connected with the base is need to be replaced together.

(25) In other words, in the prior art, there is no device that the rolling brush assembly and the connection assembly can be installed or disassembled in a portable way. The rolling brush assembly is connected with the connection assembly non-detachably, so they need to be replaced together when replacing. It can be imagined that the cost waste caused by this is very high for both users and manufacturers.

(26) In view of the above problems, the present application provides a solution that the rolling brush assembly and the connection assembly can be installed or disassembled in a portable way, and the installed rolling brush assembly will not be affected during use. The specific solution is as follows.

(27) Referring to FIG. 1 to FIG. 4, FIG. 1 provides a cleaning device, which includes a device body 200 and a floor brush assembly 100 connected with the device body 200, and with a cooperation of the device body 200 and the floor brush assembly 100, the surface to be cleaned can be cleaned.

(28) FIG. 2 shows a floor brush assembly 100, which includes a rolling brush assembly 1, a connection assembly 2 and a base 3. The rolling brush assembly 1 is connected with the base 3 through the connection assembly 2. In the prior art, it is necessary to replace the rolling brush assembly 1 together with the connection assembly 2 when replacing the rolling brush assembly 1.

(29) However, in the solution of the present application, the connection assembly 2 and the rolling brush assembly 1 are connected through an installation assembly 201, the installation assembly 201 includes a control rod 2011. When the control rod 2011 is configured to move along its axis, the rolling brush assembly 1 and the connection assembly 2 can be separated. In other words, in the solution of the present application, the rolling brush assembly 1 can be disassembled through the control rod 2011, and it should be understood that the rolling brush assembly 1 can also be installed through the installation assembly 201.

(30) Referring to FIG. 3, it can be seen that FIG. 3 illustrates a state in which the rolling brush assembly 1 is disengaged from the connection assembly 2 through the installation assembly 201. At this time, when replacing the rolling brush assembly 1, it is no longer necessary to replace the rolling brush assembly 1 together with the connection assembly 2.

(31) Referring to FIG. 4, it shows a state where the rolling brush assembly 1 is connected with the connection assembly 2. The rolling brush assembly 1 can be reliably installed through the installation assembly 201, and then it can be connected with the base 3 for cleaning.

(32) Specifically, the rolling brush assembly 1 includes a rolling brush body 102 and a support portion 101 provided on a side of the rolling brush body 102. It should be understood that the support portion 101 here can be provided on an inner side of the rolling brush body 102 and located on a side of the rolling brush body 102, or can be directly connected with an outside of the rolling brush body 102. The rolling brush body 102 has a rolling brush cavity 103 (as see in FIG. 3).

(33) The connection assembly 2 includes a connection body 202, an end of the connection body 202 is connected with the base 3 through the installation assembly 201, and the support portion 101 is rotatably connected with respect to the installation assembly 201, so that the rolling brush body 102 is rotatably connected with respect to the installation assembly 201 via the support portion 101.

(34) The installation assembly 201 further includes the control rod 2011. In an implementation, the installation assembly 201 can be disconnected from the support portion 101 by moving the control rod 2011, so that the assembly or disassembly of the rolling brush assembly 1 can be controlled by manipulating the control rod 2011. It should be noted that the movement of the control rod 2011 here can be manually operated by the user, and of course it can also be automatically operated by automatic device, such as it can realize the movement of the control rod 2011 by cooperating with some driving structures. The driving structures here can be a gear and rack, a screw, a cam, an air tube and other structures.

(35) In an implementation, the movement of the control rod 2011 can be configured to be movable along an axial direction of the control rod 2011. That is, from a perspective of a movement mode, the control rod 2011 can be controlled to move by a pressing mode or a pulling mode.

(36) Specifically, the pressing mode is to drive the control rod 2011 to move towards the support portion 101, and the pulling mode is to drive the control rod 2011 to move away from the support portion 101 or to drive the control rod 2011 to move close to the connection body 202.

(37) Please continue to refer to FIG. 5 and FIG. 6, FIG. 5 shows an implementation of the installation assembly 201. Specifically, the installation assembly 201 includes a control rod 2011, and the support portion 101 is sleeved on the outer side of the control rod 2011, and a fixing element 2016 is provided between the support portion 101 and the control rod 2011, and the fixing element 2016 is connected with the support portion 101 and the control rod 2011; when the control rod 2011 is driven to move, the fixing element 2016 is disengaged from the support portion 101, so that the support portion 101 can be separated from the control rod 2011.

(38) Here, the disengagement means that the fixing element 2016 also moves under the movement of the control rod 2011, so that it is no longer in contact with the support portion 101, so as to realize the disengagement between the fixing element 2016 and the support portion 101.

(39) Of course, in another implementation, the control rod 2011 can be directly disengaged from the support portion 101 through its own deformation. Specifically, the support portion 101 is sleeved on the outer side of the control rod 2011, and when it needs to be disengaged, the control rod 2011 is driven to move, so that the control rod 2011 contracts and deforms, and the support portion 101 can be separated from the control rod 2011.

(40) In normal use, the control rod 2011 abuts against the support portion 101, that is, the control rod 2011 is directly connected with the support portion 101. When it is necessary to be disengaged, the control rod 2011 is contracted to form a gap with the support portion 101, so that the rolling brush assembly 1 can be disengaged.

(41) In an implementation, the control rod 2011 is also provided with a position limiting portion 2017, the position limiting portion 2017 abuts against the fixing element 2016 during normal use, and when the rolling brush assembly 1 needs to be disassembled, the position limiting portion 2017 is driven to move by driving the control rod 2011 to move, so that the fixing element 2016 loses its abutting force and is disengaged from the support portion 101. It should be understood that the movement of the control rod 2011 here includes both moving towards the support portion 101 and moving away from the support portion 101.

(42) The above-mentioned position limiting by the position limiting portion 2017 enables the fixing element 2016 to be more reliably fixed and disengaged, thus making the usage experience better.

(43) Please continue to refer to FIG. 5, FIG. 6 and FIG. 8. In an implementation, the position limiting portion 2017 includes a position limiting groove 20172, and a side of the position limiting groove 20172 is provided with a first slope portion 20171. In normal use, the first slope portion 20171 abuts against the fixing element 2016, so that the support portion 101 is connected with the control rod 2011. When the control rod 2011 moves, the first slope portion 20171 moves and disengages from the fixing element 2016, so that the rolling brush assembly 1 can be replaced.

(44) In an implementation, as shown in FIG. 5, the first slope portion 20171 is provided on a side of the position limiting groove 20172 away from the connection body 202. On this basis, by driving the control rod 2011 to move towards the support portion 101, the first slope portion 20171 can be disengaged from the fixing element 2016, so that the rolling brush assembly 1 can be replaced.

(45) In another implementation, the first slope portion 20171 can of course also be provided on a side of the position limiting groove 20172 close to the connection body 202. By driving the control rod 2011 to move away from the support portion 101, the first slope portion 20171 can be disengaged from the fixing element 2016, and the rolling brush assembly 1 can be replaced in the same way.

(46) In an implementation, the position limiting portion 2017 is configured as a boss structure, and the specific solution is as follows.

(47) Referring to FIG. 7 and FIG. 9, the position limiting portion 2017 provided on the control rod 2011 includes a position limiting boss 20173 and a second slope portion 20174 provided on a side of the position limiting boss 20173. Similarly, during normal use, the position limiting boss 20173 abuts against the fixing element 2016, thus providing an abutting force for the fixing element 2016 to ensure its connection with the support portion 101. After the control rod 2011 is driven by an external force to move, the position limiting boss 20173 gradually disengages from the fixing element 2016. The fixing element 2016 gradually loses connection with the support portion 101 along the second slope portion 20174, so that the fixing element 2016 is disengaged from the support portion 101.

(48) It should be understood that two driving modes of the control rod 2011 are also included here, and the specific solution is as follows.

(49) Please continue to refer to FIG. 7 and FIG. 9. The second slope portion 20174 is provided on a side of the position limiting boss 20173 close to the connection body 202. On this basis, when the control rod 2011 is driven to move towards the support portion 101, the position limiting boss 20173 will gradually disengage from the fixing element 2016, and the fixing element 2016 will also disengage from the support portion 101 along the second slope portion 20174.

(50) In an implementation, the second slope portion 20174 is provided on a side of the position limiting boss 20173 away from the connection body 202. On this basis, when the control rod 2011 is driven to move away from the support portion 101, the position limiting boss 20173 and the fixing element 2016 will be disengaged, and the fixing element 2016 will also disengage from the support portion 101 along the second slope portion 20174.

(51) It should be noted in particular that the slope portion here is not limited to an inclined plane, of course, it can also be a cambered surface or a surface with other shapes.

(52) In an implementation, a deformation of the control rod 2011 itself and its cooperation with the fixing element 2016 can be used to realize the installation or disassembly, the specific solution is as follows.

(53) With reference to FIG. 10, the solution that the control rod 2011 can be directly disengaged from the support portion 101 through its own deformation has been introduced above, while a solution introduced here is to use a deformation of the control rod 2011 itself and its cooperation with the fixing element 2016 to disengage from the support portion 101. The specific solution is as follows.

(54) The fixing element 2016 is provided between the control rod 2011 and the support portion 101. When the control rod 2011 is contracted inward under an action of external force, the fixing element 2016 loses an abutting force of the control rod 2011 applied thereto, so that the fixing element 2016 is gradually disengaged from the support portion 101.

(55) In an implementation, the fixing element 2016 is configured as a buckle (not shown in the figure) in the control rod 2011, and a buckle groove (not shown in the figure) matched with the buckle in the control rod 2011 is provided in the support portion 101.

(56) In normal use, the buckle in the control rod 2011 is engaged with the buckle groove of the support portion 101, so as to realize a connection between the control rod 2011 and the support portion 101. When replacement is needed, the buckle is disengaged from the buckle groove by driving the control rod 2011 to achieve the purpose of replacing the rolling brush assembly 1.

(57) Please continue to refer to FIG. 10, in another implementation, the installation assembly 201 includes a support tube 2014, a control rod 2011 is inserted into the support tube 2014, and a fixing element 2016 passes through the support tube 2014 and is respectively connected with the control rod 2011 and the support portion 101.

(58) A first protrusion 20112 is provided on the outer side of the control rod 2011, and a second protrusion 20144 is provided on the inner side of the support tube 2014, and an end of the control rod 2011 is provided with at least one notch penetrated through the control rod 2011 radially. When the control rod 2011 moves, the first protrusion 20112 contacts the second protrusion 20144, because the control rod 2011 is provided with a notch penetrated through the control rod 2011. Therefore, the second protrusion 20144 forces the control rod 2011 to contract towards the notch, thereby achieving the purpose of contracting the control rod 2011, and thus realizing the disengagement of the fixing element 2016 from the support portion 101.

(59) Of course, the above-mentioned contraction mode is only one solution provided in the present application, and other solutions can be adopted, for example, the control rod 2011 is at least partially set to an elastically contractible structure. Therefore, when the control rod 2011 moves the elastically contractible structure to the position of the fixing element 2016, through a contraction of the control rod 2011, the disengagement of the fixing element 2016 from the support portion 101 is realized.

(60) Please refer to FIG. 5 to FIG. 7, the connection assembly 2 includes a connection body 202. One end of the connection body 202 is connected with the installation assembly 201, and the other end of the connection body 202 is connected with the base 3. In the present implementation, the connection body 202 can be a plate structure or a columnar structure, etc.

(61) An end of the connection body 202 is provided with an installation boss 2020, a bearing 2015 is provided in the installation boss 2020, and the support tube 2014 is provided in the bearing 2015, so that the support tube 2014 can rotate.

(62) The control rod 2011 is inserted into the support tube 2014 and connected with the support portion 101 through the fixing element 2016, so that the support portion 101 can rotate relative to the connection body 202, that is, the rotation of the rolling brush assembly 1 and the effective connection are ensured here, and at the same time, the rolling brush assembly 1 can be disassembled or assembled conveniently.

(63) Please continue to refer to FIG. 5 to FIG. 7. In the multiple implementations provided above, the fixing element 2016 is configured as a ball structure. In other words, in one or more implementations, the fixing element 2016 is configured as a roll ball. The use of a ball structure can make it easier for the fixing element 2016 to be disengaged from the support portion 101. Compared with a structure with sharp corners, the surface of the ball structure is smoother and less likely to be stuck.

(64) Various solutions for disassembly or assembly by using the fixing element 2016 have been described above, and most of the above solutions are described by using a single fixing element 2016. However, in the solution of the present application, a solution for fixing by using a plurality of fixing elements 2016 is also provided. When a single fixing element 2016 is connected, it may be easy to an unstable condition such as shaking because there is only one angle or plane being subjected to a connection force.

(65) In order to solve the above problem, the control rod 2011 can be provided with a plurality of fixing elements 2016 around its axial direction. Of course, the control method is similar to the above solutions, and the above control methods are also used for a disengagement control, that is, when the control rod 2011 is driven to move, for example, when the control rod 2011 is driven to move towards the support portion 101, the multiple fixing elements 2016 are disengaged from the support portion 101.

(66) At the same time, in order to prevent the control rod 2011 from disengaged when moving, the present application also provides a solution that can limit a position of the control rod 2011, the specific solution is as follows.

(67) Referring to FIG. 11, the control rod 2011 is inserted into and beyond the support tube 2014, and a position limiting ring 2019 is provided on a side beyond the support tube 2014 and close to the support portion 101, and the position limiting ring 2019 protrudes from a connection port between the control rod 2011 and the support tube 2014, so that the control rod 2011 can be prevented from being disengaged from the connection body 202 or can be limited at a proper position, thereby limiting an extending distance of the control rod 2011.

(68) The solutions of moving and controlling the disengagement or assembly of the control rod 2011 are introduced in detail above. On this basis, the present application also provides a solution for reset. The specific solution is as follows.

(69) Please refer to FIG. 7, a fourth protrusion 20143 is provided on an inner side of the support tube 2014, and a third protrusion 20111 is provided on an outer side of the control rod 2011. The control rod 2011 is sleeved with a spring 2012, one end of the spring 2012 abuts against the fourth protrusion 20143 and the other end of the spring 2012 abuts against the third protrusion 20111.

(70) In this way, after the control rod 2011 is moved, it can be reset by the spring 2012. From the perspective of user experience, resetting by the spring 2012 will lead to a more convenient disassembly and assembly.

(71) In another implementation, due to the fixing element 2016 penetrates through the support tube 2014, and based on the fixing element 2016 being a spherical structure, if the rolling brush assembly 1 is replaced, after the rolling brush assembly 1 is disassembled, the fixing element 2016 will easily come out towards an outer side of the support tube 2014 because an end of the fixing element 2016 loses its dependence. In order to solve the above problems, the present application also provides a solution that can effectively prevent the fixing element 2016 from coming out in the above-mentioned scenario.

(72) Please refer to FIG. 12-FIG. 14. An accommodation port 2013 is opened on the outer side of the support tube 2014, and a diameter of the accommodation port 2013 is at least equal to a diameter of the fixing element 2016, so that it can be ensure that the fixing element 2016 can penetrate through the support tube 2014. In order to prevent the fixing element 2016 from coming out, a snap ring 2018 is added, the snap ring 2018 includes an outer ring and an inner ring, the outer ring is adapted to a size of the opening of the accommodation port 2013, and the inner ring is adapted to a spherical surface of the fixing element 2016.

(73) When installing the support tube 2014 and the fixing element 2016, the fixing element 2016 can be set in the accommodation port 2013 first, and then the snap ring 2018 can be clamped on the outer side of the fixing element 2016 and connected with the accommodation port 2013.

(74) It should be understood that a connection mode here is not limited, and it can be connected by gluing or buckling, so that the stability of the fixing element 2016 when installing or disassembling the rolling brush assembly 1 can be further ensured through the arrangement of the snap ring 2018.

(75) A connection relationship between the support portion 101 and the support tube 2014 has been described above, and the support portion 101 can be used to support and rotate through the support tube 2014. It should be understood that the rotation speed of the rolling brush of the cleaning device in a cleaning process is relatively high. Therefore, there may be a risk of disengagement or slippage between the support tube 2014 and the support portion 101. Based on this, the present application also provides a solution to solve the above problem, the specific solution is as follows.

(76) Please refer to FIG. 11 and FIG. 17, the support tube 2014 includes a fixing section 20141 and a connection section 20142. The fixing section 20141 is cylindrical structure and is sleeved on an inner circle of the bearing 2015. The connection section 20142 is set to a square structure, and an interior of the support portion 101 is provided with a square notch matched with the square structure, and the connection section 20142 is inserted into the square notch. Therefore, the rotary transmission between the support portion 101 and the support tube 2014 includes two ways. The first way is that a fixing element 2016 connects the support tube 2014 and the support portion 101, so that when the support tube 2014 rotates, it will naturally drive the support portion 101 to rotate; the second way is that the support tube 2014 and the support portion 101 are both in a square structure, due to the square structure, when the support tube 2014 rotates, it can drive the support portion 101 to rotate through the above four corners.

(77) That is, the above-mentioned rotation is carried out by means of a cooperation of the two ways, thus making the transmission more stable.

(78) It is described above that by a cooperation of the square structures, an enhanced stability can be achieved when rotating, but at the same time, the above solution will also bring a defect, that is, the cooperation of the square structures will aggravate the wear, especially the above-mentioned sharp corner structure. In order to solve the above problem, the present application also provides a solution that can alleviate the wear, the specific solution is as follows.

(79) As shown in FIG. 11, FIG. 15 and FIG. 16, a fixing ring 1012 is provided in the support portion 101, the fixing ring 1012 is configured to be made of a metal material, and the control rod 2011 is provided in the fixing ring 1012, that is, the connection section 20142 is inserted into the fixing ring 1012.

(80) In an implementation, the fixing ring 1012 is connected with the connection section 20142 through a square structure. Due to the fixing ring 1012 is made of metal material, its hardness is relatively higher, and its wear can be alleviated in a high-speed rotation, which means that the use of the fixing ring 1012 not only ensures the stability of transmission, but also solves the problem that the fixing ring 1012 is easy to wear.

(81) The solution of connecting the control rod 2011 with the support portion 101 through the fixing element 2016 has been described in detail above. On this basis, the present application also provides a solution that can improve the stability of the fixing element 2016 and the support portion 101 after assembly, the specific solution is as follows.

(82) The inner side of the support portion 101 is provided with a bayonet 1011 for accommodating a part of the fixing element 2016. When the fixing element 2016 is connected with the support portion 101, the part of the fixing element 2016 can be clamped in the bayonet 1011, so that a connection stability between the fixing element 2016 and the support portion 101 can be enhanced.

(83) Further, the bayonet 1011 can be provided on one side or both sides of the support portion 101, which makes it easier to open the bayonet 1011.

(84) Of course, in another implementation, the bayonet 1011 can also be provided on the fixing ring 1012, as shown in FIG. 15 and FIG. 16. The bayonet 1011 is an arc-shaped notch 10122 provided on one side or both sides of the fixing ring 1012, and the fixing ring 1012 includes a main body 10121, in which a clamping cavity 10123 is provided, and a support tube 2014 is clamped in the clamping cavity 10123. The arc-shaped notch 10122 is provided at one side or both sides of the clamping cavity 10123.

(85) When the fixing element 2016 is in contact with the fixing ring 1012, the fixing element 2016 is clamped in the arc-shaped notch 10122, so as to realize a more stable connection.
