[0052] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0053] Reference is made below to Figures 1 - 7 describe the cleaning device 1000 and the cleaning system according to an embodiment of the first aspect of the present utility model.

[0054] Referring to Figures 1 - 7 , according to an embodiment of the first aspect of the present utility model, the cleaning device 1000 includes: a device body 200, a first cleaning module 100, and a second driving assembly 5. The first cleaning module 100 and the second driving assembly 5 are both provided on the device body 200. The first cleaning module 100 includes a cleaning assembly 1 and a first driving assembly 2. The first driving assembly 2 is connected to the cleaning assembly 1. The cleaning assembly 1 includes a cleaning member 11. The cleaning member 11 includes a cleaning portion 1122. The cleaning portion 1122 is used to contact the working surface to clean the working surface. The first driving assembly 2 is configured to drive the cleaning portion 1122 to move between a first height position and a second height position. When the cleaning portion 1122 is located at the first height position, the cleaning portion 1122 contacts the working surface. When the cleaning portion 1122 is located at the second height position, the cleaning portion 1122 is disengaged from the working surface.

[0055] For example, when the cleaning device 1000 performs a cleaning task, the cleaning portion 1122 can be lifted from the first height position to the second height position relative to the device body 200 so that the cleaning portion 1122 is disengaged from the working surface, to avoid secondary contamination 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.

[0056] Optionally, the cleaning assembly 11 includes a cleaning member 11 and a cleaning housing 12. A part of the cleaning member 11 is located inside the cleaning housing 12 and includes one or more cleaning members 112 spaced circumferentially along the cleaning housing 12. The cleaning member 112 has a cleaning portion 1122.

[0057] The second driving component 5 is installed on the device body 200 and is drivingly connected to the first cleaning module 100. The second driving component 5 is configured to drive the first cleaning module 100 to move between a retracted position and an extended position, wherein the extended position is farther from the center of the device body 200 than the retracted position. When in the retracted position, the cleaning component 11 of the first cleaning module 100 is close to the center of the device body 200, and at this time the cleaning range is small. When in the extended position, the cleaning component 11 of the first cleaning module 100 is far from the center of the device body 200, and at this time the cleaning range is larger. By enabling the cleaning position to swing between the retracted position and the extended position, it is beneficial to expand the overall cleaning range of the cleaning device 1000 according to the working requirements of the cleaning device 1000.

[0058] During the process of the first cleaning module 100 moving from the retracted position to the extended position, the first cleaning module 100 swings in a direction away from the center of the device body 200; during the process of the first cleaning module 100 moving from the extended position to the retracted position, the first cleaning module 100 swings in a direction close to the center of the device body 200.

[0059] Optionally, the first cleaning module 100 can be a side brush module, and the cleaning component 11 includes a side brush; optionally, the first cleaning module 100 can also be a mopping module, and the cleaning component 11 includes a mop.

[0060] For example, when the cleaning device 1000 is a floor sweeping robot and the cleaning component 11 is a side brush module, when the cleaning device 1000 needs to clean a corner, the second driving component 5 drives the first cleaning module 100 to swing from the retracted position to the extended position so that the cleaning component 11 can clean the corner area; after the cleaning component 11 finishes cleaning the corner area, the first driving component 2 drives the cleaning component 11 to swing from the extended position to the retracted position.

[0061] For example, to expand the cleaning range of the cleaning device 1000, the second driving component 5 drives the first cleaning module 100 to swing from the retracted position to the extended position. When the first cleaning module 100 encounters water stains, stains, etc. on the working surface in the extended position, the first driving component 2 drives the cleaning part 1122 to lift from the first height position to the second height position to avoid causing secondary pollution to the working surface.

[0062] According to the cleaning device 1000 of the embodiments of the present utility model, by providing a first driving component 2 and a second driving component 5, and configuring the first driving component 2 to drive the cleaning part 1122 to move between a first height position and a second height position, and configuring the second driving component 5 to drive the first cleaning module 100 to move between a retracted position and an extended position. In this way, during the working process of the cleaning device 1000 performing the cleaning task, through the cooperation of the overall position change of the first cleaning module 100 between the retracted position and the extended position and the position change of the cleaning part 1122 between the first height position and the second height position, the cleaning device 1000 can have more diverse functional modes, so as to better meet the user's usage requirements. For example, when the first cleaning module 100 is in the extended position to clean the working surface, the cleaning part 1122 can also avoid water stains, stains, etc. existing on the working surface by moving to the second height position. In this way, while expanding the cleaning range of the cleaning device 1000, it can also avoid causing secondary pollution to the working surface.

The winding wheel 9 is adapted to wind the towing rope 8 thereon and to release the towing rope 8.

[0081] Optionally, during the process of the first cleaning module 100 moving from the retracted position to the extended position, the second driving motor 51 rotates forward and drives the winding wheel 9 to rotate to release the towing rope 8. The towing rope 8 loosens to remove the traction force on the first cleaning module 100, and the first elastic member 7 drives the first cleaning module 100 to move in the direction of the extended position; during the process of the first cleaning module 100 moving from the extended position to the retracted position, the second driving motor 51 rotates in reverse and drives the winding wheel 9 to rotate to wind the towing rope 8 on the winding wheel 9. The towing rope 8 is tensioned and applies a traction force to the first cleaning module 100, and the towing rope 8 drives the first cleaning module 100 to move in the direction of the retracted position.

[0082] By providing the towing rope 8 and the winding wheel 9, the cooperation between the towing rope 8 and the winding wheel 9 can realize driving the first cleaning module 100 to move between the retracted position and the extended position, and the space occupied by the towing rope 8 and the winding wheel 9 during the transmission process is also small, which is convenient for the component layout of the cleaning device 1000.

A part of the cleaning member 11 is disposed inside the cleaning housing. The first driving assembly 2 includes a first driving motor 21, a first transmission mechanism 22 and a restraint 23. The first transmission mechanism 22 is disposed inside the transmission box body 3 and is drivably connected between the motor shaft of the first driving motor 21 and the cleaning member 11. The restraint 23 is disposed on the transmission box body 3 and is used to restrict the cleaning housing 12 from rotating in a set direction.

[0084] Optionally, the restraint 23 can be used to directly restrict the cleaning housing 12 from rotating in a set direction; optionally, the restraint 23 can also be used to indirectly restrict the rotation of the cleaning housing 12 in a set direction. For example, the cleaning member 11 can rotate in a first rotation direction or a second rotation direction, and the restraint 23 can be used to restrict the cleaning housing 12 from rotating in the second rotation direction.

[0085] For example, the second height position is higher than the first height position. When the cleaning part 1122 is at the first height position and the first driving motor 21 rotates in the first direction, the first driving motor 21 drives the cleaning part 1122 to rotate; during the process of the cleaning part 1122 rising from the first height position to the second height position, the first driving motor 21 rotates in the second direction. The first driving motor 21 drives the cleaning part 1122 to rotate and the cleaning part 1122 rises relative to the cleaning housing 12. The restraining member 23 restricts the rotation of the cleaning housing 12. The second direction is opposite to the first direction; during the process of the cleaning part 1122 descending from the second height position to the first height position, the first driving motor 21 rotates in the first direction. The first driving motor 21 drives the cleaning part 1122 to rotate and the cleaning part 1122 descends relative to the cleaning housing 12.

In this way, structures such as a separate driving motor for driving the cleaning part 1122 to move up and down can be omitted, which is beneficial to simplifying the structural arrangement of the cleaning module, and thus is also beneficial to the miniaturization of the cleaning module, etc.

[0087] Reference Figures 5 - 6 Referring to, according to some optional embodiments of the present invention, the first driving assembly 2 includes a transmission shaft 24. The transmission shaft 24 is arranged in the cleaning housing 12 and is fixed relative to the cleaning housing 12, so that a stable transmission relationship is formed between the transmission shaft 24 and the cleaning housing 12. The restraining member 23 cooperates with the transmission shaft 24 to restrict the transmission shaft 24 from rotating in a set direction. For example, the transmission shaft 24 extends in the up and down direction, the restraining member 23 is arranged at the upper end of the transmission shaft 24, and the cleaning housing 12 is fixed at the lower end of the transmission shaft 24.

[0088] For example, the transmission shaft 24 and the cleaning housing 12 are connected by fasteners. Optionally, the cleaning housing 12 includes a detachable upper housing 121 and a lower housing 122. For example, a hole with a polygon cross-section is formed in the lower housing 122, and the cross-section at the lower end of the transmission shaft 24 is formed into a polygon adapted to the hole, and the lower end of the transmission shaft 24 is inserted into the hole.

[0089] Reference Figures 5 - 6 Referring to, according to some optional embodiments of the present invention, the restraining member 23 is sleeved on the outer peripheral side of the transmission shaft 24. By sleeving the restraining member 23 on the outer peripheral side of the transmission shaft 24, the installation relationship between the restraining member 23 and the transmission shaft 24 is simple and convenient for assembly.

By making the restraint member 23 a one-way bearing, the one-way bearing can stably restrain the rotation of the transmission shaft 24 in a certain set direction, so that the rotation of the cleaning housing 12 in a certain set direction can be stably restrained.

[0091] Reference Figures 5 - 6 , according to some alternative embodiments of the present utility model, the first transmission mechanism 22 includes a first transmission gear 221 and a second transmission gear 222 that are drivably connected. The first transmission gear 221 is installed on the motor shaft of the first driving motor 21, and the second transmission gear 222 is sleeved on the outer peripheral side of the transmission shaft 24 and is connected to the cleaning member 11. Among them, the second transmission gear 222 being sleeved on the transmission shaft 24 means that there is no transmission relationship between the second transmission gear 222 and the transmission shaft 24, and the second transmission gear 222 can rotate relative to the transmission shaft 24. For example, there is a clearance fit between the second transmission gear 222 and the transmission shaft 24. By providing the first transmission gear 221 and the second transmission gear 222, the driving force of the first driving motor 21 can be stably transmitted to the cleaning member 11; by making the second transmission gear 222 sleeved on the outer peripheral side of the transmission shaft 24, in the case where the rotation of the transmission shaft 24 is restrained by the restraint member 23, the second transmission gear 222 can drive the cleaning member 11 to rotate relative to the transmission shaft 24, so that the cleaning member 11 can move relative to the cleaning housing 12 towards the second height position.

[0092] Optionally, there is also one or more intermediate transmission gears between the first transmission gear 221 and the second transmission gear 222.

[0093] Reference Figures 5 - 6 , according to some alternative embodiments of the present utility model, the restraint member 23 is located on the side of the second transmission gear 222 away from the cleaning member 11. By making the restraint member 23 located on the side of the second transmission gear 222 away from the cleaning member 11, the layout relationship among the restraint member 23, the second transmission gear 222, and the cleaning member 11 is reasonable, and it can prevent the restraint member 23 from interfering with the second transmission gear 222 from transmitting power to the cleaning member 11.

[0096] By making the cross-section of the connection hole 41 polygonal and making the cross-section of the connection shaft 2221 inserted into the connection hole 41 a polygon adapted to the shape of the connection hole 41, it is suitable for the assembly between the transmission ring 4 and the connection shaft 2221 and stable and efficient power transmission can be carried out between the transmission ring 4 and the connection shaft 2221, so that the transmission shaft 24 can stably drive the cleaning component 11 to rotate.

[0097] Reference Figures 5 - 6 , according to some alternative embodiments of the present utility model, the second height position is higher than the first height position. When the cleaning part 1122 is at the first height position and the first driving motor 21 rotates in the first direction, the first driving motor 21 drives the cleaning part 1122 to rotate; during the process of the cleaning part 1122 rising from the first height position to the second height position, the first driving motor 21 rotates in the second direction, the first driving motor 21 drives the cleaning part 1122 to rotate and the cleaning part 1122 rises relative to the cleaning housing 12, and the restraint 23 restricts the rotation of the cleaning housing 12, and the second direction is opposite to the first direction; during the process of the cleaning part 1122 descending from the second height position to the first height position, the first driving motor 21 rotates in the first direction, the first driving motor 21 drives the cleaning part 1122 to rotate and the cleaning part 1122 descends relative to the cleaning housing 12. In this way, structures such as a driving motor specifically used for driving the lifting of the cleaning part 1122 can be omitted, which is beneficial to simplifying the structural arrangement of the cleaning module, and thus is also beneficial to the miniaturization of the cleaning module, etc.

[0098] Reference Figures 1 - 6, according to some embodiments of the present utility model, the cleaning assembly 1 further includes a cleaning housing 12. A part of the cleaning member 11 is located inside the cleaning housing 12 and includes one or more cleaning elements 112 spaced circumferentially along the cleaning housing 12. Avoidance holes 123 for avoiding the cleaning elements 112 are formed on the cleaning housing 12. The inner wall of the avoidance hole 123 includes a driving surface 124 and a guiding inclined surface 125. The guiding inclined surface 125 extends obliquely upward in the circumferential direction of the cleaning housing 12. When the cleaning element 112 cooperates with the guiding inclined surface 125, the guiding inclined surface 125 is used to guide the cleaning part 1122 to move between a first height position and a second height position. When the cleaning element 112 cooperates with the driving surface 124, the cleaning member 11 drives the cleaning housing 12 to rotate synchronously to clean the working surface. By providing the guiding inclined surface 125 and the driving surface 124 on the cleaning housing 12, under the driving action of the first driving motor 21, the synchronous rotation of the cleaning member 11 and the cleaning housing 12 can be realized through the cooperation of the cleaning member 11 and the driving surface 124, so that when the first cleaning module 100 completes the cleaning task of the working surface; the movement of the cleaning part 1122 between the first height position and the second height position can be realized through the cooperation of the cleaning member 11 and the guiding inclined surface 125, and the structure of the guiding inclined surface 125 is simple.

[0099] Reference Figure 5 , according to some alternative embodiments of the present utility model, the cleaning member 11 further includes a mounting seat 111 connected to the cleaning element 112. The cleaning element 112 includes a connecting arm 1121 and a cleaning part 1122. The connecting arm 1121 is connected between the mounting seat 111 and the cleaning part 1122. For example, the cleaning member 11 includes a plurality of cleaning elements 112, and the plurality of cleaning elements 112 are spaced circumferentially along the cleaning housing 12 and connected to the mounting seat 111. The mounting seat 111 is located inside the cleaning housing 12, and the cleaning part 1122 is located outside the cleaning housing 12. The cleaning housing 12 includes an upper housing 121 and a lower housing 122 connected to each other. An avoidance hole 123 for avoiding the connecting arm 1121 is defined between the upper housing 121 and the lower housing 122. The inner wall of the avoidance hole 123 includes a driving surface 124 and a guiding inclined surface 125 formed on the lower housing 122. The guiding inclined surface 125 extends obliquely upward in the circumferential direction of the lower housing 122.

[0100] The mounting seat 111 being located inside the cleaning housing 12 is beneficial to enhancing the overall stability and durability, and provides a stable foundation for the cleaning part 1122, ensuring the stability of the cleaning assembly 1 even during high-speed rotation or strong cleaning operations, reducing vibration, and improving the overall durability and service life.

[0101] Optionally, the connecting arm 1121 is a flexible connecting arm 1121. When the cleaning part 1122 receives an impact or a strike, the flexible connecting arm 1121 can absorb a certain amount of impact force, which can reduce or avoid damage to the cleaning assembly 1 and is beneficial to improving the service life of the cleaning module.

[0102] Optionally, the connecting arm 1121 is a flexible connecting arm 1121. During the process of the first driving assembly 2 driving the cleaning part 11 to rotate, the connecting arm 1121 of the cleaning part 11 can move along the guiding inclined surface 125. During the movement of the connecting arm 1121, the connecting arm 1121 will undergo elastic deformation under the action of the cleaning housing 12 to drive the cleaning part 1122 to be lifted from the first height position to the second height position.

[0103] Optionally, the guiding inclined surface 125 includes an inclined surface section and a horizontal section, and the horizontal section is connected to the upper end of the inclined surface section. During the process of the cleaning part 11 moving upward relative to the upper housing 121 along the guiding inclined surface 125, when the cleaning part 11 moves upward to be in vertical cooperation with the horizontal section, the cleaning part 1122 completes the upward lifting.

[0104] For example, when the first driving motor 21 rotates in the reverse direction, the first driving assembly 2 drives the cleaning part 11 to rotate along the second direction through the mounting seat 111. The connecting arm 1121 cooperates with the guiding inclined surface 125. The connecting arm 1121 is a flexible arm. The guiding inclined surface 125 causes the connecting arm 1121 to undergo elastic deformation and guides the cleaning part 1122 to move upward from the first height position to the second height position relative to the lower housing 122. When the first driving motor 21 rotates in the forward direction, the first driving assembly 2 drives the cleaning part 11 to rotate along the first direction through the mounting seat 111. The connecting arm 1121 cooperates with the guiding inclined surface 125. The guiding inclined surface 125 guides the connecting arm 1121 to move downward relative to the lower housing 122. The elastic deformation of the connecting arm 1121 gradually recovers and drives the cleaning part 1122 to move from the first height position to the second height position until the connecting arm 1121 cooperates with the driving surface 124, and the cleaning part 11 drives the cleaning housing 12 to rotate synchronously so that the cleaning part 11 can clean the working surface.

[0105] For example, when the cleaning component 11 is in the first height position relative to the cleaning housing 12, the first driving motor 21 rotates in the first direction, and the first driving motor 21 drives the cleaning component 11 to rotate in the first rotation direction. The connecting arm 1121 cooperates with the driving surface 124. At this time, the restraint member 23 allows the cleaning housing 12 to rotate in the second rotation direction, and the cleaning component 11 drives the cleaning housing 12 to rotate synchronously. When the cleaning part 1122 needs to move upward from the first height position to the second height position, the first driving motor 21 rotates in the second direction, and the restraint member 23 restricts the rotation of the cleaning housing 12 in the second rotation direction, so that the first driving motor 21 can drive the cleaning part 1122 to move from the first height position to the second height position relative to the lower housing 122 along the guiding inclined surface 125.

[0106] Optionally, the cleaning device 1000 may further include a second elastic member 10. The cleaning housing 12 includes an upper housing 121 and a lower housing 122 that are detachably connected. The second elastic member 10 abuts between the upper housing 121 and the lower housing 122 in the up-and-down direction. When the cleaning part 1122 is lifted upward under the guiding action of the guiding inclined surface 125, the cleaning part 1122 can also drive the upper housing 121 to move upward relative to the lower housing 122 during the lifting process, so as to avoid the upper housing 121 interfering with the upward lifting of the cleaning part 1122 due to the limited height space of the avoidance hole 123 defined between the upper housing 121 and the lower housing 122 in the up-and-down direction, which is beneficial to increasing the height that the cleaning component 11 can be lifted upward.

[0107] Optionally, when the height that the cleaning part 1122 needs to be lifted upward is fixed, by making the upper housing 121 movable relative to the lower housing 122 in the up-and-down direction between the second position and the first position, in this way, during the process of the cleaning part 1122 moving upward relative to the lower housing 122, it can be lifted upward by driving the upper housing 121 to move upward together. In this way, the height of the avoidance hole 123 defined between the upper housing 121 and the lower housing 122 can be reduced, and the height space that the cleaning housing 12 needs to reserve for the movement of the cleaning component 11 in the up-and-down direction can be reduced, which is beneficial to reducing the size of the cleaning housing 12.

[0108] According to some optional embodiments of the present invention, the first cleaning module 100 is adjacent to the outer periphery of the device body 200. Optionally, the first cleaning module 100 is a side brush module, which enables the first cleaning module 100 to effectively clean narrow areas around walls, furniture feet or other obstacles, etc.; the first cleaning module 100 can also be a mopping module. By making the first cleaning module 100 adjacent to the outer periphery of the device body 200, it is beneficial to expand the cleaning range of the cleaning device 1000.

[0109] According to some alternative embodiments of the present utility model, there are multiple first cleaning modules 100, and the multiple first cleaning modules 100 are arranged at intervals along the circumferential direction of the device body 200. By providing multiple first cleaning modules 100 and arranging them at intervals along the circumferential direction of the device body, it is beneficial to further increase the cleaning area of the first cleaning modules 100, thereby further improving the cleaning effect of the cleaning device 1000.

[0110] According to some alternative embodiments of the present utility model, it further includes a second cleaning module installed on the device body 200. The second cleaning module is the main cleaning module and is arranged adjacent to the center of the device body 200. For example, the second cleaning module is a roller brush module. By providing that the cleaning device 1000 further includes a main cleaning module arranged adjacent to the center of the device body 200, and the cleaning area covered by the main cleaning module is relatively large, it is beneficial for the cleaning device 1000 to efficiently clean the working surface.

[0111] According to some alternative embodiments of the present utility model, the first cleaning modules 100 and the second cleaning module are arranged at intervals in the front-rear direction. By arranging the first cleaning modules 100 and the second cleaning module at intervals in the front-rear direction, this can avoid interference between the first cleaning modules 100 when cleaning the working surface, and at the same time, it is beneficial to achieve cleaning coverage of different areas of the working surface.
