The cleaning component rotates to clean a working surface (such as a floor, a carpet, etc.), and the cleaning device has multiple cleaning functions (such as sweeping, mopping, etc.). However, when the cleaning device performs a cleaning task, when the cleaning component encounters water stains or dirt on the working surface, it is easy to cause secondary pollution to the working surface, or the cleaning component is prone to collide with or interfere with the working surface at some protruding positions on the working surface. Therefore, improvement is needed. Summary of the Utility Model

[0059] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0060] Reference will be made below to Figures 1 - 4 describe a cleaning module 100, a cleaning device, and a cleaning system according to an embodiment of the present invention.

[0061] Reference is made to Figures 1 - 4 , according to a cleaning module 100 of the first aspect embodiment of the present invention, the cleaning module 100 includes: a cleaning assembly 1, a driving assembly 2, and a lifting assembly. The cleaning assembly 1 includes a cleaning member, and the cleaning member includes at least one cleaning member 11 for cleaning an operation surface. The cleaning member 11 is used to contact the operation surface to clean the operation surface. The portion of the cleaning member 11 for contacting the operation surface is a cleaning portion 113. The driving assembly 2 is connected to the cleaning assembly 1 to drive the cleaning assembly 1 to rotate. Optionally, the cleaning member 11 can be one or more.

[0062] The lifting assembly includes a shaft rod 31 which extends in the vertical direction, and the lower end of the shaft rod 31 is drivably connected to the cleaning member 11. The cleaning portion 113 has a cleaning position and a retracted position, the cleaning position is below the retracted position, and the cleaning portion 113 is movable relative to the shaft rod 31 in the vertical direction between the cleaning position and the retracted position.

[0063] Optionally, when the cleaning portion 113 is in the retracted position, there is a gap between the cleaning portion 113 and the working surface; when the cleaning portion 113 is in the cleaning position, the cleaning portion 113 contacts the working surface to clean the working surface.

[0064] The cleaning portion 113 is movable in the vertical direction. In this way, when the cleaning module 100 is applied to a cleaning device, when the cleaning device performs a cleaning task, the cleaning portion 113 can be lifted relative to the device body 5 so that there is a gap between the cleaning portion 113 and the working surface to avoid secondary pollution of the working surface by the cleaning assembly 1 or to avoid collisions and interferences between the cleaning assembly 1 and the working surface at certain positions of the working surface.

[0065] According to the cleaning module of the embodiment of the present invention, by making the cleaning portion movable between the cleaning position and the retracted position, during the process of cleaning the working surface by the cleaning module, the cleaning portion can avoid secondary pollution of the working surface by the cleaning assembly by lifting upward to the retracted position, or avoid collisions and interferences between the cleaning component and the protruding position of the working surface, etc.

[0066] Reference Figures 1 - 4 , according to the cleaning module 100 of the embodiment of the present invention, the lifting assembly further includes a constraint assembly 33. When the driving assembly 2 drives the cleaning assembly 1 to rotate in the first direction, the constraint assembly 33 is used to constrain the shaft rod 31 from rotating in the first direction, so that the cleaning portion 113 moves downward relative to the shaft rod 31 from the retracted position to the cleaning position.

[0067] When the cleaning portion 113 moves downward to the cleaning position, the constraint assembly 33 releases the constraint on the shaft rod 31 from rotating in the first direction or the driving assembly 2 overcomes the constraint of the constraint assembly 33 on the shaft rod 31 from rotating in the first direction, and the driving assembly 2 drives the cleaning assembly 1 to rotate in the first direction and drives the shaft rod 31 to rotate synchronously, so that the cleaning portion 113 cleans the working surface.

[0068] When the driving assembly 2 drives the cleaning assembly 1 to rotate in the second direction, the constraint assembly 33 is used to constrain the shaft rod 31 from rotating in the second direction, so that the cleaning portion 113 moves upward relative to the shaft rod 31 from the cleaning position to the retracted position, and the second direction is opposite to the first direction. The constraint of the constraint assembly 33 on the shaft rod 31 includes preventing the shaft rod 31 from rotating in the set direction or restricting the shaft rod 31 from rotating in the set direction by friction.

[0069] Optionally, the constraint component 33 includes a first constraint structure 331. The first constraint structure 331 includes two meshing parts. During the process of the cleaning part 113 moving downward from the retracted position to the cleaning position relative to the shaft rod 31, the two parts of the first constraint structure 331 are in a meshing state, and the constraint component 33 can be used to prevent the shaft rod 31 from rotating in the first direction; when the cleaning part 113 moves to the cleaning position, the two parts of the first constraint structure 331 are disengaged from the meshing state, and the constraint component 33 releases the constraint on the shaft rod 31 rotating in the first direction.

[0070] Optionally, the constraint component 33 includes a first constraint structure 331. The first constraint structure 331 includes two parts that cooperate with each other by friction. During the process of the cleaning part 113 moving downward from the retracted position to the cleaning position relative to the shaft rod 31, the friction between the two parts of the first constraint structure 331 enables the constraint component 33 to restrict the shaft rod 31 from rotating in the first direction; when the cleaning part 113 moves to the cleaning position, the driving component 2 can increase the drive so that the shaft rod 31 can overcome the friction between the two parts of the first constraint structure 331 to release the constraint on the shaft rod 31 rotating in the first direction.

[0071] For example, the driving component 2 includes a driving motor 21. In the initial state of the cleaning module 100, the cleaning component 1 is spaced apart from the working surface. The driving motor 21 rotates forward, and the driving motor 21 drives the cleaning part 11 to rotate in the first direction. The constraint component 33 restricts the shaft rod 31 from rotating in the first direction. The cleaning part 113 moves downward from the retracted position to the cleaning position relative to the shaft rod 31 so that the position where the cleaning part 113 contacts the working surface can clean the working surface; when the cleaning part 113 moves to the cleaning position, the constraint component 33 releases the restriction on the shaft rod 31 rotating in the first direction, so that the driving component 2 drives the cleaning component 1 to rotate in the first direction and drives the shaft rod 31 to rotate synchronously, so that the cleaning part 113 can clean the working surface; when the cleaning work is completed or when situations such as secondary pollution of the working surface occur, the driving motor 21 rotates in reverse, and the driving motor 21 drives the cleaning component 1 to rotate in the second direction. The constraint component 33 restricts the shaft rod 31 from rotating in the second direction so that the cleaning part 113 moves upward from the cleaning position to the retracted position relative to the shaft rod 31.

[0072] When the cleaning module 100 is applied to a cleaning device, during the process of the cleaning part 113 moving in the up and down direction, the cleaning part 113 can still rotate under the driving action of the driving component 2. For example, there are some positions with different heights on the working surface. In this way, the cleaning part 113 can still rotate during the up and down movement, which is beneficial to effectively clean these positions. In this way, according to the working needs of the cleaning device, the cleaning module 100 can not only handle flat surfaces, but also be applicable to some slightly undulating surfaces, enhancing the comprehensiveness and efficiency of the cleaning work.

[0073] Optionally, the cleaning component 1 can be a mopping component, or the cleaning component 1 can also be a side brush component. Optionally, the cleaning part 113 is a cleaning brush.

[0074] Optionally, the constraint component 33 can include one or more constraint structures.

[0075] Optionally, there is a threaded connection between the cleaning part 113 and the shaft rod 31. When the driving component 2 drives the cleaning component 1 to rotate in the first direction and the constraint component 33 restricts the shaft rod 31 from rotating in the first direction, the cleaning part 113 of the cleaning component 1 moves downward from the retracted position to the cleaning position under the guidance of the thread.

[0076] By providing the constraint component 33 that cooperates with the shaft rod 31, during the process of the driving component 2 driving the cleaning component 1 to rotate, through the constraint of the constraint component 33 on the rotation of the shaft rod 31 in the first direction or the second direction, the cleaning part 113 of the cleaning component 1 can move up and down relative to the shaft rod 31 between the cleaning position and the retracted position. In this way, the driving component 2 can simultaneously drive the cleaning component 1 to rotate and the cleaning part 113 of the cleaning part 11 to move up and down, which can eliminate the need to separately provide or simplify the provision of relevant mechanisms for driving the cleaning part 113 to move up and down. For example, a driving motor 21 for driving the cleaning part 11 to move up and down can be omitted, which is beneficial to simplifying the structure of the cleaning module 100, reducing the layout difficulty of the cleaning device, and facilitating the miniaturization of the cleaning device.

[0077] Reference Figures 1 - 4 , according to some embodiments of the present invention, the constraint component 33 includes a first constraint structure 331 and a second constraint structure 332. Among them, the first constraint structure 331 is used to restrict the shaft rod 31 from rotating in the first direction. When the cleaning part 113 moves downward to the cleaning position, the first constraint structure 331 releases the constraint on the shaft rod 31 from rotating in the first direction or the driving component 2 overcomes the constraint of the first constraint structure 331 on the shaft rod 31 from rotating in the first direction; the second constraint structure 332 is used to restrict the shaft rod 31 from rotating in the second direction.

[0078] For example, the driving assembly 2 includes a driving motor 21. In the initial state of the cleaning module 100, the cleaning part 113 is in the retracted position, and the cleaning assembly 1 is spaced apart from the working surface. The driving motor 21 rotates forward, and the driving motor 21 drives the cleaning member 11 to rotate in the first direction. The first constraint structure 331 restricts the rotation of the shaft rod 31 in the first direction. The cleaning part 113 moves downward relative to the shaft rod 31 from the retracted position to the cleaning position, so that the cleaning member 11 moves downward to a position in contact with the working surface to clean the working surface. When the cleaning part 113 moves to the cleaning position, the constraint assembly 33 releases the restriction on the rotation of the shaft rod 31 in the first direction, so that the driving assembly 2 drives the cleaning assembly 1 to rotate in the first direction and drives the shaft rod 31 to rotate synchronously, so that the cleaning part 113 cleans the working surface. When the cleaning work is completed or when situations such as secondary pollution of the working surface occur, the driving motor 21 rotates reversely, and the driving motor 21 drives the cleaning assembly 1 to rotate in the second direction and drives the mating part 32 to rotate in the second direction. The second constraint structure 332 restricts the rotation of the shaft rod 31 in the second direction. The cleaning part 113 moves upward relative to the shaft rod 31 from the cleaning position to the retracted position, so that the cleaning member 11 is lifted upward to a position spaced apart from the working surface.

[0079] By making the constraint assembly 33 include the first constraint structure 331 and the second constraint structure 332, and making the first constraint structure 331 and the second constraint structure 332 be respectively used to restrict the rotation of the shaft rod 31 in the first direction and the rotation in the second direction, the restriction effect of the constraint assembly 33 on the rotation of the shaft rod 31 can be more precise. Through precise control, overloading or unnecessary wear is avoided, and the overall efficiency and durability of the cleaning module 100 are improved. In addition, such an arrangement also facilitates the separate maintenance and replacement of the first constraint structure 331 and the second constraint structure 332.

[0080] Reference Figures 1 - 4 , according to some optional embodiments of the present invention, the first constraint structure 331 and the second constraint structure 332 are arranged in the up-down direction.

[0081] According to some optional embodiments of the present invention, the first constraint structure 331 restricts the rotation of the shaft rod 31 in the first direction by the frictional force on the shaft rod 31, and the second constraint structure 332 restricts the rotation of the shaft rod 31 in the first direction by blocking the shaft rod 31.

[0082] Reference Figures 1 - 4, according to some alternative embodiments of the present utility model, the first restraint structure 331 restrains the rotation of the shaft rod 31 in the first direction by the frictional force on the shaft rod 31, and the second restraint structure 332 restrains the rotation of the shaft rod 31 in the second direction by blocking the shaft rod 31. By making the first restraint structure 331 restrain the rotation of the shaft rod 31 in the first direction by the frictional force on the shaft rod 31, the structure of the frictional restraint is simple and the installation is convenient. Moreover, in this way, the first restraint structure 331 can absorb a certain amount of vibration and shock, which helps to reduce the vibration and noise of the system and improve the running stability. And when the cleaning part 113 moves to the cleaning position, only by overcoming the restraint effect generated by the frictional force of the first restraint structure 331 can the shaft rod 31 rotate with the cleaning assembly 1, so that the cleaning assembly 1 can operate normally. In this way, it is no longer necessary to set up corresponding other structures to enable the cleaning assembly 1 to operate normally at the cleaning position. By making the second restraint structure 332 restrain the rotation of the shaft rod 31 in the first direction by blocking the shaft rod 31, the rotation of the shaft rod 31 in the second direction can be stably restrained by the second restraint structure 332.

[0083] Reference Figures 1 - 4 , according to some alternative embodiments of the present utility model, the first restraint structure 331 is a damping structure, and the second restraint structure 332 is a one-way bearing sleeved on the outer peripheral side of the shaft rod 31. The damping structure is flexible in setting and can be switched in state, so that the first restraint structure 331 can not only meet the requirement of restraining the rotation of the shaft rod 31 in the first direction so that the cleaning part 113 can move from the retracted position to the cleaning position, but also when the cleaning part 113 is in the cleaning position, the first restraint structure 331 can make the shaft rod 31 rotate along the first direction with the cleaning assembly 1 by means of releasing the restraint or overcoming the restraint of the first restraint structure 331; while the one-way bearing can stably restrain the rotation of the shaft rod 31 in the second direction.

[0084] Reference Figures 1 - 4 , according to some alternative embodiments of the present utility model, it further includes a box body 4 having a receiving cavity, at least part of the driving assembly 2 is disposed in the receiving cavity, the cleaning assembly 1 is located outside the box body 4, the first restraint structure 331 is located above the second restraint structure 332, the shaft rod 31 is rotatably disposed in the receiving cavity and the lower end of the shaft rod 31 extends downward out of the receiving cavity, the first restraint structure 331 includes a damping cover 3311, a damping ring 3312 is sleeved on the upper end of the shaft rod 31, and the damping ring 3312 is fixed relative to the shaft rod 31, the damping cover 3311 is fixed to the box body 4, and the damping ring 3312 is detachably engaged with the damping cover 3311.

[0085] Wherein, when the damping ring 3312 cooperates with the damping cover 3311, the first constraint structure 331 is used to constrain the shaft rod 31 to rotate in the first direction; when the damping ring 3312 is disengaged from the damping cover 3311, the first constraint structure 331 releases the constraint on the shaft rod 31 to rotate in the first direction.

[0086] Wherein, at least part of the driving mechanism being disposed in the accommodating cavity may include the following several situations: For example, part of the driving mechanism is located in the accommodating cavity. The driving mechanism includes a driving motor 21 and a transmission member, wherein the transmission member is disposed in the accommodating cavity and the driving motor 21 is located outside the accommodating cavity. Again for example, the entire driving mechanism is located in the accommodating cavity. The driving mechanism includes a driving motor 21 and a transmission member, and both the driving motor 21 and the transmission member are disposed in the accommodating cavity.

[0087] By making the first damping mechanism include a damping cover 3311 fixed to the box body 4, and a damping ring 3312 sleeved on the upper end of the shaft rod 31 and fixed relative to the shaft rod 31, and making the damping ring 3312 and the damping cover 3311 detachably cooperate, it is possible to simply and flexibly enable or disable the rotation restriction of the first damping structure on the shaft rod 31 in the first direction when needed, realizing refined management of the rotation control of the shaft rod 31. In addition, the damping ring 3312 and the damping cover 3311 are detachably cooperated. If the damping ring 3312 or the damping cover 3311 is worn or needs to be adjusted, maintenance personnel can quickly check, clean or replace them respectively, without the need to disassemble the entire first damping structure complexly, thereby simplifying the maintenance work and reducing the maintenance cost and time.

[0088] For example, during the process of the cleaning part 113 moving downward from the retracted position to the cleaning position, the damping ring 3312 cooperates with the damping cover 3311 to restrict the rotation of the shaft rod 31 in the first direction. For example, when the cleaning part 113 is in the cleaning position, the damping ring 3312 and the damping cover 3311 are separated to release the constraint of the first constraint structure 331 on the shaft rod 31 to rotate in the first direction.

[0089] Reference Figures 1 - 4 , according to some optional embodiments of the present invention, when the damping ring 3312 cooperates with the damping cover 3311, the damping ring 3312 meshes with or cooperates with the damping cover 3311 by friction.

[0090] Optionally, a plurality of engaging ribs are formed on the upper surface of the damping ring 3312 and are circumferentially and spacedly distributed along the damping ring 3312, and a plurality of engaging grooves are formed on the lower surface of the damping cover 3311 and are circumferentially and spacedly distributed along the damping ring 3312. The plurality of engaging ribs are respectively received in the engaging grooves so that the damping ring 3312 and the damping cover 3311 are meshed.

[0091] When the damping ring 3312 and the damping cover 3311 are fitted together, the damping ring 3312 meshes with or fits against the damping cover 3311 by frictional force, so that a stable fitting relationship can be formed between the damping ring 3312 and the damping cover 3311, thereby enabling the first damping structure to effectively limit the rotation of the shaft rod 31 in the first direction. By using a frictional force or a direct meshing fitting method, the damping function can be achieved without additional complex mechanical devices, which is beneficial to simplifying the design, reducing costs and reducing potential failure points.

[0092] Reference Figures 1 - 4 , according to some alternative embodiments of the present utility model, a fitting groove 3313 is formed on the upper surface of the damping ring 3312, and a downwardly protruding fitting protrusion 3314 is formed on the damping plastic cover. Wherein, when the damping ring 3312 and the damping cover 3311 are fitted together, the fitting protrusion 3314 is received in the fitting groove 3313; when the damping ring 3312 and the damping cover 3311 are disengaged from each other, the fitting protrusion 3314 is disengaged from the fitting groove 3313.

[0093] By forming a fitting groove 3313 on the upper surface of the damping ring 3312, a downwardly protruding fitting protrusion 3314 on the damping plastic cover, and when the damping ring 3312 and the damping cover 3311 are fitted together, the fitting protrusion 3314 is received in the fitting groove 3313, so that during the assembly process of the cleaning module 100, the matching relationship between the fitting groove 3313 and the fitting protrusion 3314 can be referred to for positioning so that the two can be accurately aligned when combined, forming a tight connection. This can not only effectively transmit the required damping force, but also prevent loosening or functional failure caused by misalignment, improving the stability and reliability of the entire system. And the fitting relationship between the fitting groove 3313 and the fitting protrusion 3314 is beneficial to further improving the damping effect of the first damping structure.

[0094] For example, the outer peripheral wall of the fitting protrusion 3314 meshes with or fits against the inner peripheral wall of the fitting groove 3313 by frictional force. For example, the upper surface of the fitting protrusion 3314 meshes with or fits against the bottom of the fitting groove 3313 by frictional force.

[0095] Optionally, a plurality of meshing ribs are formed on the outer peripheral wall of the fitting protrusion 3314 and are circumferentially spaced apart along the damping ring 3312, and a plurality of meshing grooves are formed on the inner peripheral wall of the fitting groove 3313 and are circumferentially spaced apart along the damping ring 3312, and the plurality of meshing ribs are received in the meshing grooves one by one to enable meshing between the damping ring 3312 and the damping cover 3311.

[0096] Reference Figures 1 - 4, according to some alternative embodiments of the present utility model, the damping cover 3311 is a plastic cover, and the damping ring 3312 is a rubber ring. By making the damping cover 3311 a plastic cover and the damping ring 3312 a rubber ring, the damping coefficient of the rubber ring is relatively large, so that an effective damping effect can be formed between the damping ring 3312 and the damping cover 3311.

[0097] Reference Figures 1 - 4 , according to some alternative embodiments of the present utility model, the second restraint structure 332 is sleeved on the outer peripheral side of the shaft rod 31, and the second restraint structure 332 is a one-way bearing. By sleeving the second damping structure on the outer peripheral side of the shaft rod 31, the assembly relationship between the second damping structure and the shaft rod 31 is simple and the installation is convenient; and by making the second damping structure a one-way bearing, the one-way bearing can form a stable and effective limiting effect on the rotation of the shaft rod 31 in the second direction.

[0098] Reference Figures 1 - 4 , according to some alternative embodiments of the present utility model, when the cleaning part 113 is in the cleaning position and the driving assembly 2 drives the cleaning assembly 1 to rotate in the first direction, the shaft rod 31 can move downward relative to the cleaning part 11, so that the damping ring 3312 is disengaged from the damping cover 3311. After the cleaning part 113 moves to the retracted position, the cleaning part 113 rotates in the first direction. At the moment when the rotation of the shaft rod 31 does not need to be strictly restricted, the damping can be automatically released by the downward movement of the shaft rod 31, which can reduce unnecessary load, thereby reducing the working load of the driving mechanism and saving energy consumption. At the same time, the continuous wear of the damping assembly is reduced, and the service life of the first damping structure is prolonged.

[0099] Optionally, the cleaning part 113 and the shaft rod 31 are threadedly connected. After the cleaning part 113 moves to the retracted position, under the guiding action of the threaded connection, the shaft rod 31 can automatically move downward, so that the damping ring 3312 is disengaged from the damping cover 3311. This method improves the degree of automation and the convenience of use.

[0100] Reference Figures 1 - 4, according to some alternative embodiments of the present utility model, the cleaning assembly 1 includes a cleaning housing 12. The cleaning member 11 further includes a connecting arm 112, and the cleaning component further includes a mounting seat 111 connected to the connecting arm 112. The mounting seat 111 is located inside the cleaning housing 12, and the cleaning portion 113 is located outside the cleaning housing 12. The mounting seat 111 and the cleaning portion 113 are connected by the connecting arm 112. A through hole 123 for the connecting arm 112 to pass through is formed on the outer peripheral wall of the cleaning housing 12. The connecting arm 112 is a flexible arm. The lower end of the shaft rod 31 is drivably connected to the mounting seat 111. The mounting seat 111 can move relative to the shaft rod 31 between a first position and a second position in the up and down direction, so that the mounting seat 111 can float up and down inside the cleaning housing 12, and the cleaning portion 113 can move between a cleaning position and a retracted position in the up and down direction.

[0101] When the mounting seat 111 is in the first position, the cleaning portion 113 is in the retracted position; when the mounting seat 111 is in the second position, the cleaning portion 113 is in the cleaning position. During the process that the mounting seat 111 moves between the first position and the second position relative to the shaft rod 31 in the up and down direction, the cleaning portion 113 moves between the retracted position and the cleaning position relative to the shaft rod 31 in the up and down direction. For example, the first position is below the second position. During the process that the cleaning portion 113 moves upward from the first position to the second position, the cleaning portion 113 moves downward from the retracted position to the cleaning position; for example, during the process that the cleaning portion 113 moves downward from the second position to the first position, the cleaning portion 113 moves upward from the cleaning position to the retracted position.

[0102] When the cleaning portion 113 moves upward to the retracted position and the driving assembly 2 stops working, the mounting seat 111 moves upward relative to the cleaning housing 12 under the elastic force of the connecting arm 112, so as to drive the shaft rod 31 to move upward, so that the damping ring 3312 cooperates with the damping cover 3311.

[0103] By making the mounting seat 111 located in the second position and when the driving mechanism stops working, the mounting seat 111 moves upward relative to the cleaning housing 12 under the elastic force of the connecting arm 112, so as to drive the shaft rod 31 to move upward, so that the damping ring 3312 cooperates with the damping cover 3311. Such a setting enables the cooperation relationship between the damping ring 3312 and the damping cover 3311 to be automatically restored after the mounting seat 111 moves to the second position and the cleaning member 11 moves upward to a state spaced apart from the working surface. So that when the cleaning portion 113 needs to move downward to the cleaning position next time, the first damping structure can effectively restrict the rotation of the shaft rod 31 in the first direction, so that the cleaning module 100 can operate and work normally subsequently, improving the reliability and consistency of the cleaning module 100.

[0104] For example, the driving mechanism includes a driving motor 21. In the initial state of the cleaning module 100, the mounting base 111 is in the first position, the cleaning part 113 is in the retracted position, and the cleaning assembly 1 is spaced apart from the working surface. The driving motor 21 rotates forward, driving the cleaning member 11 to rotate in the first direction and driving the mounting base 111 to rotate in the first direction. The damping ring 3312 and the damping cover 3311 cooperate to restrict the rotation of the shaft rod 31 in the first direction. The mounting base 111 moves upward relative to the shaft rod 31 from the first position to the first position, so that the cleaning member 11 moves downward to a position in contact with the working surface for cleaning the working surface; when the mounting base 111 is in the first position, the cleaning module 100 switches from the first state to the second state, and the shaft rod 31 can move downward relative to the mounting base 111, and the damping ring 3312 and the damping cover 3311 are disengaged to release the restriction on the rotation of the shaft rod 31 in the first direction; the driving motor 21 rotates reversely, driving the cleaning assembly 1 to rotate in the second direction and driving the mounting base 111 to rotate in the second direction. The one-way bearing restricts the rotation of the shaft rod 31 in the second direction. The mounting base 111 moves downward relative to the shaft rod 31 from the first position to the second position, so that the cleaning member 11 is lifted upward to a position spaced apart from the working surface, and the mounting base 111 moves upward relative to the cleaning housing 12 under the elastic force of the connecting arm 112 to drive the shaft rod 31 to move upward, so that the damping ring 3312 cooperates with the damping cover 3311.

[0105] Reference Figures 1 - 4 , according to some alternative embodiments of the present invention, the lifting assembly includes a fitting 32. A fitting section 311 is formed at the lower end of the shaft rod 31. The fitting 32 is fixed to the cleaning member 11 and is threadedly connected to the fitting section 311. The fitting 32 is movable relative to the shaft rod 31 in the up-and-down direction between a first position and a second position. By making the lifting assembly include the fitting 32 fixed to the cleaning member 11 and threadedly connecting it to the fitting section 311 of the screw rod, the thread can guide the fitting 32. In the case where the restraining assembly 33 restricts the rotation of the shaft rod 31, the fitting 32 drives the cleaning member 11 to move in the up-and-down direction between the first position and the second position under its guiding action.

[0106] Reference Figures 1 - 4 , according to some alternative embodiments of the present invention, a threaded hole 321 is formed in the fitting 32, and an external thread portion 3111 that is threadedly engaged with the threaded hole 321 is formed on the outer peripheral wall of the fitting section 311. By forming the threaded hole 321 in the fitting 32 and forming the external thread portion 3111 that is threadedly engaged with the threaded hole 321 on the outer peripheral wall of the fitting section 311, the assembly relationship between the fitting 32 and the fitting section 311 is simple.

[0107] Optionally, the first position is above the second position. When the fitting 32 is in the second position, the cleaning member 11 contacts the working surface to clean the working surface; when the fitting 32 moves upward from the second position to the first position, the cleaning member 11 is lifted upward to separate the cleaning member 11 from the working surface; when the fitting 32 moves from the first position to the second position again, the cleaning member 11 moves downward to contact the working surface for cleaning the working surface.

[0108] Optionally, the first position is above the second position. When the fitting 32 is in the first position, the cleaning member 11 contacts the working surface to clean the working surface; when the fitting 32 moves downward from the first position to the second position, the cleaning member 11 is lifted upward to separate the cleaning member 11 from the working surface; when the fitting 32 moves from the second position to the first position again, the cleaning member 11 moves downward to contact the working surface for cleaning the working surface.

[0109] Optionally, the fitting 32 and the shaft 31 are formed as metal parts.

[0110] For example, the driving assembly 2 includes a driving motor 21. In the initial state of the cleaning module 100, the fitting 32 is in the second position, and the cleaning assembly 1 is spaced apart from the working surface. The driving motor 21 rotates forward, the driving motor 21 drives the cleaning member 11 to rotate in the first direction and drives the fitting 32 to rotate in the first direction. The constraint assembly 33 restricts the shaft 31 from rotating in the first direction. The fitting 32 moves upward from the second position to the first position relative to the shaft 31, so that the cleaning member 11 moves downward to a position in contact with the working surface for cleaning the working surface; when the fitting 32 is in the first position, the cleaning module 100 switches from the first state to the second state, and the constraint assembly 33 releases the restriction on the shaft 31 from rotating in the first direction; the driving motor 21 rotates in reverse, the driving motor 21 drives the cleaning assembly 1 to rotate in the second direction and drives the fitting 32 to rotate in the second direction. The constraint assembly 33 restricts the shaft 31 from rotating in the second direction. The fitting 32 moves downward from the first position to the second position relative to the shaft 31, so that the cleaning member 11 is lifted upward to a position spaced apart from the working surface.

[0111] Reference Figures 1 - 4 , according to some optional embodiments of the present invention, the cleaning assembly 1 includes a cleaning housing 12. The cleaning member 11 includes a connected mounting base 111, a connecting arm 112, and a cleaning portion 113. The mounting base 111 is located inside the cleaning housing 12, enhancing the overall stability and durability: the mounting base 111 is fixed inside the cleaning housing 12, providing a stable foundation for the cleaning portion 113, ensuring the stability of the assembly even during high-speed rotation or strong cleaning operations, reducing vibration, and improving the overall durability and service life.

[0112] The cleaning part 113 is located outside the cleaning housing 12. The mounting seat 111 and the cleaning part 113 are connected by a connecting arm 112. A through hole 123 for the connecting arm 112 to pass through is formed on the outer peripheral wall of the cleaning housing 12. The cleaning housing 12 is designed with a through hole 123 for the connecting arm 112 to pass through. In this way, while ensuring the movement of the cleaning part 113, a large opening on the cleaning housing 12 is avoided, the structural strength of the housing is maintained, and the design complexity and manufacturing cost are reduced.

[0113] The fitting 32 is fixed to the mounting seat 111. The cleaning part 11 can move up and down relative to the cleaning housing 12. The driving mechanism is connected to the cleaning housing 12 to drive the cleaning assembly 1 to rotate. The direct connection of the driving mechanism to the cleaning housing 12 can transfer power more directly and efficiently, enabling the cleaning assembly 1 to complete the rotational movement more quickly and accurately, improving the cleaning efficiency. In addition, this integration method also helps to optimize the space utilization of the entire system and simplify the layout of the drive system.

[0114] By making the cleaning part 11 include a connected mounting seat 111, a connecting arm 112, and a cleaning part 113, the cleaning part 113 is located outside the cleaning housing 12 and is connected to the mounting seat 111 through the connecting arm 112. This layout makes it convenient for the cleaning part 113 to clean the working surface. The setting of the connecting arm 112 enables the cleaning part 113 to have a certain range of movement, enhancing the flexibility of cleaning.

[0115] Reference Figures 1 - 4 , according to some alternative embodiments of the present invention, there are multiple cleaning parts 11, and the multiple cleaning parts 11 are arranged at intervals along the circumferential direction of the cleaning housing 12. By making there be multiple cleaning parts 11 and arranging the multiple cleaning parts 11 at intervals along the circumferential direction of the cleaning housing 12, this is beneficial to improving the cleaning effect of the cleaning parts 11.

[0116] Reference Figures 1 - 4 , according to some alternative embodiments of the present invention, the connecting arm 112 is a flexible arm, and the mounting seat 111 can float in the up and down direction so that the cleaning part 113 can move in the up and down direction. By making the connecting arm 112 a flexible arm, the cleaning part 113 can better adapt to different working surfaces. Even for uneven or complex geometric working surfaces, a closer contact can be obtained, improving the cleaning effect. And compared with a rigid structure, the flexible arm can respond more gently when contacting the working surface. The design of the flexible arm can bend moderately when encountering an obstacle to reduce direct impact, and can avoid or reduce the situation of breakage or damage of the cleaning part 11 during use. At the same time, the floating mounting seat 111 can reduce the loss caused by hard impact or friction, extending the service life of the device.

[0117] For example, the first position is above the second position. When the fitting 32 is in the first position, the cleaning member 11 contacts the working surface to clean the working surface; when the fitting 32 moves downward from the first position to the second position, the flexible arm undergoes elastic deformation, and the cleaning member 11 is lifted upward to separate the cleaning member 11 from the working surface; when the fitting 32 moves from the second position to the first position again, the flexible arm gradually returns from the elastically deformed state, and the cleaning member 11 moves downward to contact the working surface for cleaning the working surface.

[0118] Reference Figures 1 - 4 , according to some optional embodiments of the present utility model, the cleaning housing 12 includes an upper housing 121 and a lower housing 122 that are detachably connected, and a through hole 123 is defined between the upper housing 121 and the lower housing 122. By making the cleaning housing 12 include a detachable upper housing and a lower housing 122, it is convenient to install the cleaning member 11 on the cleaning housing 12, which is beneficial to the assembly of the cleaning module 100.

[0119] Reference Figures 1 - 4 , optionally, the upper housing 121 is further formed with an avoidance notch for avoiding the cleaning portion 113, and the avoidance notch is opposite and communicated with the through hole 123 in the up-down direction.

[0120] Reference Figures 1 - 4 , optionally, the flexible arm includes a first flexible section, a second flexible section, and a third flexible section that are sequentially connected. The first flexible section is located inside the cleaning housing 12 and connected to the mounting seat 111, the second flexible section passes through the through hole 123, and the third flexible section is located outside the cleaning housing 12.

[0121] When the fitting 32 is in the first position, the first flexible section is in an undeformed state, the second flexible section is spaced apart from the lower housing 122 of the flexible section, the third flexible section is in an undeformed state, and the cleaning portion 113 contacts the working surface.

[0122] When the fitting 32 is in the second position, the fitting 32 drives the first flexible section to bend downward through the mounting seat 111, the second flexible section is supported at the through hole 123 of the lower housing 122, the third flexible section warps upward, and a gap is formed between the cleaning portion 113 and the working surface.

[0123] Reference Figures 1 - 4, according to some alternative embodiments of the present utility model, the driving mechanism includes a driving motor 21 and a first transmission member 22. The first transmission member 22 is sleeved on the outer peripheral side of the shaft rod 31 in an idle manner, and there is no transmission relationship between the first transmission member 22 and the shaft rod 31. Moreover, the first transmission member 22 is located above the cleaning assembly 1, and the first transmission member 22 is connected to the cleaning housing 12. The driving motor 21 is connected to the first transmission member 22 to drive the first transmission member 22 to rotate. By connecting the first transmission member 22 to the cleaning housing 12, the driving force from the driving motor 21 can be stably and efficiently transmitted to the cleaning housing 12, so that the cleaning assembly 1 can be stably driven to rotate.

[0124] Reference Figures 1 - 4 , according to some alternative embodiments of the present utility model, the first transmission member 22 is detachably connected to the cleaning housing 12. By making the first transmission assembly detachably connected to the cleaning housing 12, it is convenient to separately inspect, maintain, and replace the first transmission member 22 and the cleaning housing 12, etc.

[0125] Optionally, the first transmission member 22 includes a gear portion and a fixing portion provided at the lower end of the gear portion. The fixing portion is detachably connected to the cleaning housing 12, and the fixing portion and the gear portion are detachably connected.

[0126] Reference Figures 1 - 4 , according to some alternative embodiments of the present utility model, a clamping hole 222 is formed on one of the first transmission member 22 and the cleaning housing 12, and a clamping buckle 124 is formed on the other. The clamping buckle 124 is in clamping fit with the clamping hole 222. The way of the clamping buckle 124 being in clamping fit with the clamping hole 222 is simple in assembly and stable in connection relationship, which is beneficial to the stable power transmission between the first transmission member 22 and the cleaning housing 12.

[0127] For example, a clamping buckle 124 is formed on the first transmission member 22, and a clamping hole 222 is formed on the cleaning housing 12. The clamping buckle 124 is in clamping fit with the clamping hole 222 so that the first transmission member 22 and the cleaning housing 12 are in transmission connection. Another example is that a clamping hole 222 is formed on the first transmission member 22, and a clamping buckle 124 is formed on the cleaning housing 12. The clamping buckle 124 is in clamping fit with the clamping hole 222 so that the first transmission member 22 and the cleaning housing 12 are in transmission connection.

[0128] Reference Figures 1 - 4According to some optional embodiments of the utility model, the cleaning housing 12 is provided with a plurality of buckles 124 arranged at intervals along the circumference of the cleaning housing 12, a mounting hole 221 is formed on the first transmission member 22, and the plurality of buckles 124 are located in the mounting hole 221, and a plurality of clamping holes 222 arranged at intervals along the circumference of the mounting hole 221 are formed on the inner peripheral wall of the mounting hole 221, and the number of the clamping holes 222 is the same as the number of the buckles 124 and corresponds to each other one by one. By forming the mounting hole 221 on the first transmission member 22, during the assembly process of the cleaning module 100, the operator can align the cleaning housing 12 with the first transmission member 22 with reference to the position of the mounting hole 221, and then clamp the buckle 124 with the clamping hole 222, which simplifies the assembly process and also facilitates daily maintenance or replacement of the cleaning housing 12. The circumferential spacing of the plurality of buckles 124 and the clamping hole 222 can further improve the connection stability and reliability between the cleaning housing 12 and the first transmission member 22. This multi-point connection and fixing method can also evenly distribute the force, maintaining good stability even in high-speed or high-load cleaning operations, reducing the risk of loosening or deviation, and ensuring efficient and accurate cleaning operations.

[0129] refer to Figures 1 - 4 According to some optional embodiments of the utility model, the driving mechanism further includes a gear transmission mechanism, and the driving motor 21 and the first transmission member 22 are connected to each other through the gear transmission mechanism. By making the driving mechanism further include a gear transmission mechanism, the gear transmission mechanism can transmit the power of the driving motor 21 to the first transmission member 22, and the gear transmission method has higher stability.

[0130] refer to Figures 1 - 4 According to the cleaning device of the second embodiment of the utility model, the cleaning device includes: a device body 5 and the above-mentioned cleaning module 100, and the cleaning module 100 is installed on the device body 5.

[0131] According to the cleaning device of the embodiment of the utility model, by providing the above-mentioned cleaning module, by enabling the cleaning part to move between a cleaning position and a retracted position, when the cleaning module is cleaning the working surface, the cleaning part can be lifted upward to the retracted position to avoid secondary contamination of the working surface by the cleaning component, or to avoid collision and interference between the cleaning component and the protruding position of the working surface.

[0132] refer to Figures 1 - 4 According to some embodiments of the present invention, the cleaning module 100 is adjacent to the outer periphery of the device body 5. Optionally, the cleaning module 100 may be a side brush module, and by making the cleaning module 100 adjacent to the outer periphery of the device body 5, it is beneficial to expand the cleaning range of the cleaning module 100.

[0133] According to some alternative embodiments of the present utility model, there are multiple cleaning modules 100, and the multiple cleaning modules 100 are arranged at intervals along the circumferential direction of the device body 5. By having multiple cleaning modules 100, and the multiple first cleaning modules 100 being arranged at intervals along the circumferential direction of the device body 5, it is beneficial to increase the cleaning area of the first cleaning modules 100, thereby further improving the cleaning effect of the cleaning device.

[0134] According to some alternative embodiments of the present utility model, the cleaning device includes a first cleaning module 100 and a second cleaning module 100. The second cleaning module 100 is installed on the device body 5, the second cleaning module 100 is the main cleaning module 100, and the first cleaning module 100 is the auxiliary cleaning module 100 and is the cleaning module 100 according to the embodiment of the first aspect of the present utility model. For example, the second cleaning module 100 is a roller brush assembly, and the first cleaning module 100 is a side brush assembly. The setting of the side brush assembly is beneficial to improving the cleaning degree of the cleaning device at positions such as corners and the roots of walls. By making the cleaning device include a main cleaning module 100 and an auxiliary cleaning module 100, it is beneficial to improve the cleaning effect of the cleaning device.

[0135] For example, during the operation of the cleaning device, the cleaning member 11 of the auxiliary cleaning module 100 is in a state spaced apart from the working surface in the initial state. When the cleaning device needs the auxiliary cleaning device to clean the working surface, the driving motor 21 rotates forward. The driving motor 21 drives the cleaning member 11 to rotate in the first direction and drives the cooperating member 32 to rotate in the first direction. The damping ring 3312 and the damping cover 3311 of the first damping structure cooperate, and the first damping structure restricts the rotation of the shaft rod 31 in the first direction. The cooperating member 32 moves upward from the second position to the first position relative to the shaft rod 31, so that the cleaning portion 113 moves downward from the retracted position to the cleaning position in contact with the working surface to clean the working surface; when the cooperating member 32 is in the first position, the cleaning portion 113 is in the cleaning position, and the shaft rod 31 moves downward to separate the damping ring 3312 and the damping cover 3311. The first damping structure releases the restraint on the rotation of the shaft rod 31 in the first direction, and the cooperating member 32 drives the shaft rod 31 to rotate together, and the cleaning portion 113 cleans the working surface; when the auxiliary cleaning module 100 completes the cleaning operation or encounters a situation where the auxiliary cleaning module 100 may cause secondary pollution to the working surface, etc., the driving motor 21 rotates in reverse. The driving motor 21 drives the cleaning assembly 1 to rotate in the second direction and drives the cooperating member 32 to rotate in the second direction. The second damping structure restricts the rotation of the shaft rod 31 in the second direction. The cooperating member 32 moves downward from the first position to the second position relative to the shaft rod 31, so that the cleaning portion 113 is lifted upward from the cleaning position to the retracted position spaced apart from the working surface.

[0136] According to some alternative embodiments of the present utility model, the first cleaning module 100 and the second cleaning module 100 are arranged at intervals in the front-rear direction. By arranging the auxiliary cleaning module 100 and the main cleaning module 100 at intervals in the front-rear direction, it is possible to avoid interference between the main cleaning module 100 and the auxiliary cleaning module 100 when cleaning the working surface.

[0137] According to the cleaning system of the third aspect embodiment of the present utility model, the cleaning system includes: the above-mentioned cleaning device and the cleaning base station. The cleaning device is adapted to cooperate with the cleaning base station. The cleaning base station is used to clean the cleaning device and can also be used to charge the cleaning device.

[0138] According to the cleaning system of the embodiment of the present utility model, by providing the above-mentioned cleaning device, and by enabling the cleaning part to be movable between the cleaning position and the retracted position, during the process of the cleaning module cleaning the working surface, the cleaning part can avoid secondary pollution of the working surface by the cleaning component or avoid collision interference between the cleaning component and the protruding position of the working surface by lifting up to the retracted position.

[0139] Next, reference will be made to Figures 1 - 4 Describe the cleaning module 100 of some embodiments of the present utility model.

[0140] Reference Figures 1 - 4 , in this embodiment, the cleaning module 100 is applied to a cleaning device. For example, the cleaning device can be a floor sweeping robot. The cleaning module 100 includes a cleaning component 1, a driving mechanism, and a lifting component. The driving mechanism is connected to the cleaning component 1 to drive the rotation of the component 2, and the lifting component is connected to the cleaning component 1 to control the movement of the cleaning component 1 in the up-down direction.

[0141] The cleaning component 1 includes a cleaning housing 12 and a cleaning part. The cleaning part includes a mounting seat 111 and a cleaning member 11. The cleaning member 11 includes a connecting arm 112 and a cleaning member 11 connected together. The cleaning member 11 is a cleaning brush. The mounting seat 111 is located inside the cleaning housing 12, and the cleaning brush is located outside the cleaning housing 12. The mounting seat 111 and the cleaning brush are connected by the connecting arm 112. A through hole 123 for the connecting arm 112 to pass through is formed on the outer peripheral wall of the cleaning housing 12. The mating part 32 is fixed to the mounting seat 111, and the cleaning member 11 can move up and down relative to the cleaning housing 12. The cleaning housing 12 includes a detachable upper housing 121 and a lower housing 122, and the through hole 123 is defined between the upper housing 121 and the lower housing 122. There are multiple cleaning members 11, and the multiple cleaning members 11 are arranged at intervals along the circumferential direction of the cleaning housing 12. The connecting arm 112 is a flexible arm, and the mounting seat 111 can float in the up-down direction so that the cleaning brush can move in the up-down direction.

[0142] The driving mechanism includes a driving motor 21, a first transmission member 22, and a gear transmission mechanism. The driving motor 21 and the first transmission member 22 are drivingly connected through the gear transmission mechanism. The first transmission member 22 is located above the cleaning assembly 1 and is detachably connected to the cleaning housing 12. The driving motor 21 is connected to the first transmission member 22 to drive the first transmission member 22 to rotate.

[0143] The cleaning housing 12 is provided with a plurality of buckles 124 arranged at intervals along the circumferential direction of the cleaning housing 12. An installation hole 221 is formed on the first transmission member 22. The plurality of buckles 124 are located within the installation hole 221. A plurality of locking holes 222 arranged at intervals along the circumferential direction of the installation hole 221 are formed on the inner peripheral wall of the installation hole 221. The number of the locking holes 222 is the same as that of the buckles 124 and they correspond to each other one by one.

[0144] The lifting assembly includes a shaft rod 31, a mating member 32, and a damping assembly. The shaft rod 31 extends in the up and down direction and a mating section 311 is formed at the lower end of the shaft rod 31. The mating member 32 is fixed to the cleaning member 11 and is threadedly connected to the mating section 311. The first transmission member 22 is sleeved on the outer peripheral side of the shaft rod 31 and is located above the mating member 32. A threaded hole 321 is formed within the mating member 32. An external thread portion 3111 that is threadedly engaged with the threaded hole 321 is formed on the outer peripheral wall of the mating section 311.

[0145] The mating member 32 is movable relative to the shaft rod 31 between a first position and a second position in the up and down direction, so that the cleaning member 11 is movable in the up and down direction. The cleaning portion 113 is movable relative to the shaft rod 31 between a retracted position and a cleaning position in the up and down direction. When the cleaning portion 113 moves downward to the cleaning position, the constraint assembly 33 releases the constraint on the shaft rod 31 to rotate in the first direction or the driving assembly 2 overcomes the constraint of the constraint assembly 33 on the shaft rod 31 to rotate in the first direction. The driving assembly 2 drives the cleaning assembly 1 to rotate in the first direction and drives the shaft rod 31 to rotate synchronously, so that the cleaning portion 113 cleans the working surface.

[0146] Wherein, during the process of the mating member 32 moving from the second position to the first position relative to the shaft rod 31, the driving mechanism drives the mating member 32 to rotate in the first direction. The constraint assembly 33 is used to constrain the shaft rod 31 to rotate in the first direction, and the cleaning portion 113 moves from the retracted position to the cleaning position. During the process of the mating member 32 moving from the first position to the second position relative to the shaft rod 31, the driving mechanism drives the mating member 32 to rotate in the second direction. The constraint assembly 33 is used to constrain the shaft rod 31 to rotate in the second direction, and the cleaning portion 113 moves from the cleaning position to the retracted position. The second direction is opposite to the first direction.

[0147] Specifically, the damping assembly includes a first damping structure and a second damping structure arranged in the up-and-down direction. Among them, the first constraint structure 331 is used to constrain the shaft 31 to rotate in the first direction. When the cleaning part 113 moves downward to the cleaning position, the first constraint structure 331 releases the constraint on the shaft 31 to rotate in the first direction or the driving assembly 2 overcomes the constraint of the first constraint structure 331 on the shaft 31 to rotate in the first direction; the second constraint structure 332 is used to constrain the shaft 31 to rotate in the second direction.

[0148] The cleaning module 100 further includes a box body 4 having a receiving cavity. The first transmission member 22, the shaft 31 and the damping assembly are arranged in the receiving cavity. The cleaning assembly 1 is located below the box body 4. The first damping structure is located above the second damping structure. The shaft 31 is rotatably arranged in the receiving cavity and the lower end of the shaft 31 extends downward out of the receiving cavity. The first damping structure includes a damping cover 3311. A damping ring 3312 is sleeved on the upper end of the shaft 31 and is fixed relative to the shaft 31. The damping cover 3311 is fixed to the box body 4. The damping ring 3312 is detachably engaged with the damping cover 3311. When the damping ring 3312 is engaged with the damping cover 3311, the damping ring 3312 is engaged with the damping cover 3311 or is engaged by friction. A mating groove 3313 is formed on the upper surface of the damping ring. A mating protrusion 3314 protruding downward is formed on the damping plastic cover. The damping cover 3311 is a plastic cover and the damping ring 3312 is a rubber ring.

[0149] Among them, when the damping ring 3312 is engaged with the damping cover 3311, the mating protrusion 3314 is received in the mating groove 3313, and the first damping structure is used to constrain the shaft 31 to rotate in the first direction; when the damping ring 3312 is disengaged from the damping cover 3311, the mating protrusion 3314 is disengaged from the mating groove 3313, and the first damping structure releases the constraint on the shaft 31 to rotate in the first direction.

[0150] When the fitting 32 is in the first position and the driving mechanism drives the fitting 32 to rotate in the first direction, the shaft 31 can move downward relative to the fitting 32 so that the damping ring 3312 is disengaged from the damping cover 3311. When the fitting 32 is in the second position and the driving mechanism stops working, the mounting seat 111 moves upward relative to the cleaning housing 12 under the elastic force of the connecting arm 112 to drive the shaft 31 to move upward so that the damping ring 3312 is engaged with the damping cover 3311.

[0151] The second damping structure is sleeved on the outer peripheral side of the shaft 31, and the second damping structure is a one-way bearing.

[0152] For example, the driving assembly 2 includes a driving motor 21. In the initial state of the cleaning module 100, the cleaning part 113 is in the retracted position, and the cleaning assembly 1 is spaced apart from the working surface. The driving motor 21 rotates forward, and the driving motor 21 drives the cleaning member 11 to rotate in the first direction. The first constraint structure 331 restricts the shaft 31 from rotating in the first direction. The cleaning part 113 moves downward relative to the shaft 31 from the retracted position to the cleaning position, so that the cleaning member 11 moves downward to a position in contact with the working surface to clean the working surface; when the cleaning part 113 moves to the cleaning position, the constraint assembly 33 releases the restriction on the shaft 31 from rotating in the first direction, so that the driving assembly 2 drives the cleaning assembly 1 to rotate in the first direction and drives the shaft 31 to rotate synchronously, so that the cleaning part 113 cleans the working surface; when the cleaning work is completed or when situations such as secondary pollution of the working surface occur, the driving motor 21 rotates reversely, and the driving motor 21 drives the cleaning assembly 1 to rotate in the second direction and drives the mating part 32 to rotate in the second direction. The second constraint structure 332 restricts the shaft 31 from rotating in the second direction. The cleaning part 113 moves upward relative to the shaft 31 from the cleaning position to the retracted position, so that the cleaning member 11 is lifted upward to a position spaced apart from the working surface.
