[0036] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference 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.

[0037] Below, refer to Figures 1-5 to describe the cleaning device 100 according to the embodiments of the present utility model.

[0038] Refer to Figure 1 , Figure 3 and Figure 5, the cleaning device 100 according to the first aspect embodiment of the present utility model includes a device body 1 and a first cleaning module 2. The device body 1 is provided with a matching mechanism 11. The first cleaning module 2 is arranged on the device body 1 and the first cleaning module 2 includes a driving component 21 and a cleaning component 23. The cleaning component 23 is used to contact the working surface to clean the working surface. The device body 1 can provide support and fixation for the first cleaning module 2. The driving component 21 includes a driving motor 211 and a transmission component 212. The transmission component 212 includes a first transmission mechanism 213 and a second transmission mechanism 215. The first transmission mechanism 213 is drivably connected between the output end 214 of the driving motor 211 and the cleaning component 23 to drive the cleaning component 23 to rotate around its own central axis. The driving motor 211 can provide the required power for the cleaning component 23. The first transmission mechanism 213 is drivably connected between the output end 214 of the driving motor 211 and the cleaning component 23. The rotation of the output end 214 of the driving motor 211 can drive the first transmission mechanism 213 to move. The movement of the first transmission mechanism 213 can drive the cleaning component 23 to move, so as to realize that the driving motor 211 drives the cleaning component 23 to rotate around its own central axis through the first transmission mechanism 213 to clean the working surface.

[0039] The first cleaning module 2 has a retracted position and an extended position. The first cleaning module 2 moves relative to the device body 1 between the retracted position and the extended position, which is beneficial to expanding the cleaning range of the first cleaning module 2.

[0040] One end of the second transmission mechanism 215 is drivably connected to the output end 214 of the driving motor 211, and the other end of the second transmission mechanism 215 cooperates with the matching mechanism 11 to drive the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position. The output end 214 of the driving motor 211 is drivably connected to the second transmission mechanism 215. The rotation of the output end 214 of the driving motor 211 can drive the second transmission mechanism 215 to move. The other end of the second transmission mechanism 215 in motion cooperates with the matching mechanism 11, and can transmit the power output by the driving motor 211 to the matching mechanism 11, so that the matching mechanism 11 drives the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position, thereby realizing that the driving motor 211 drives the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position.

[0041] By driving the driving motor 211 to drive the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position through the second transmission mechanism 215 and the matching mechanism 11, the function of expanding the cleaning range of the cleaning device 100 can be realized.

[0042] For example, the cleaning device 100 is a floor sweeping robot, and the first cleaning module 2 is a side brush module. When the cleaning device 100 needs to clean a corner, the driving motor 211 drives the first cleaning module 2 to move from the retracted position to the extended position via the second transmission mechanism 215 and the matching mechanism 11, so that the first cleaning module 2 can clean the corner area. After the first cleaning module 2 finishes cleaning the corner area, the driving motor 211 drives the first cleaning module 2 to move from the extended position to the retracted position via the second transmission mechanism 215 and the matching mechanism 11.

[0043] The first transmission mechanism 213 is drivably connected between the output end 214 of the driving motor 211 and the cleaning component 23 to drive the cleaning component 23 to rotate about its own central axis. One end of the second transmission mechanism 215 is drivably connected to the output end 214 of the driving motor 211, and the other end of the second transmission mechanism 215 cooperates with the matching mechanism 11 to drive the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position. In this way, the driving structure for driving the cleaning component 23 to rotate about its own central axis and the driving structure for driving the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position can share a driving motor 211. Furthermore, the driving motor 211 can drive the cleaning component 23 to rotate about its own central axis to clean the working surface, and the driving motor 211 can also drive the first cleaning module 2 to move to the extended position to expand the cleaning range of the cleaning device 100. This can reduce the number of components, for example, reduce the number of driving motors 211, simplify the overall structure of the cleaning device 100, which is conducive to the layout optimization of the cleaning device 100 and also conducive to reducing the manufacturing cost of the cleaning device 100.

[0044] According to the cleaning device 100 of the embodiment of the present invention, by sharing a driving motor 211 for the driving structure for driving the cleaning component 23 to rotate about its own central axis and the driving structure for driving the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position, while realizing the movement of the first cleaning module 2 to the extended position to expand the cleaning range, the number of components can be reduced, and the overall structure of the cleaning device 100 can be simplified, which is conducive to the layout optimization of the cleaning device 100 and also conducive to reducing the manufacturing cost of the cleaning device 100.

[0045] Refer to Figure 1 and Figure 2, according to some embodiments of the present utility model, the first cleaning module 2 can swing relative to the device body 1 between a retracted position and an extended position, and the extended position is farther from the center of the device body 1 than the retracted position. The spatial area swept by the first cleaning module 2 during the swinging process is relatively large. By enabling the first cleaning module 2 to swing relative to the device body 1 between the retracted position and the extended position, and the extended position being farther from the center of the device body 1 than the retracted position, the cleaning range of the first cleaning module 2 in the extended position is farther from the center of the device body 1, thereby effectively expanding the cleaning range of the cleaning device 100.

[0046] During the process of the first cleaning module 2 moving from the retracted position to the extended position, the first cleaning module 2 moves in a direction away from the center of the device body 1; during the process of the first cleaning module 2 moving from the extended position to the retracted position, the first cleaning module 2 moves in a direction closer to the center of the device body 1.

[0047] For example, during the process of the first cleaning module 2 moving from the retracted position to the extended position, the first cleaning module 2 slides or swings in a direction away from the center of the device body 1; during the process of the first cleaning module 2 moving from the extended position to the retracted position, the first cleaning module 2 slides or swings in a direction closer to the center of the device body 1.

[0048] Refer to Figure 4 and Figure 5 , according to some embodiments of the present utility model, the engaging mechanism 11 is fixed relative to the device body 1, and the second transmission mechanism 215 meshes with the engaging mechanism 11 to drive the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position. Since one end of the second transmission mechanism 215 can be in transmission connection with the output end 214 of the driving motor 211, the other end of the second transmission mechanism 215 meshes with the engaging mechanism 11, and the rotation of the output end 214 of the driving motor 211 can drive the second transmission mechanism 215 to move. The engaging mechanism 11 is fixed relative to the device body 1, and the second transmission mechanism 215 can move relative to the engaging mechanism 11. Furthermore, the second transmission mechanism 215 can drive the first cleaning module 2 to swing relative to the device body 1 between the retracted position and the extended position, thereby effectively expanding the cleaning range of the cleaning device 100.

[0049] Refer to Figure 4 and Figure 5, according to some embodiments of the present utility model, the mating mechanism 11 includes a mating main body 111 and mating teeth 112. The mating teeth 112 are provided on the outer peripheral wall of the mating main body 111 and extend along the circumferential direction of the mating main body 111. The second transmission mechanism 215 meshes with the mating teeth 112 so that the first cleaning module 2 can swing relative to the device body 1 between a retracted position and an extended position. The second transmission mechanism 215 meshes with the mating teeth 112, causing the second transmission mechanism 215 to rotate relative to the mating mechanism 11, thereby enabling the second transmission mechanism 215 to drive the first cleaning module 2 to swing relative to the device body 1 between the retracted position and the extended position, and further expanding the cleaning range of the cleaning device 100.

[0050] For example, when the drive motor 211 operates, the rotation of the output end 214 of the drive motor 211 can drive the second transmission mechanism 215 to move. The meshing of the second transmission mechanism 215 with the mating teeth 112 can cause the second transmission mechanism 215 to rotate relative to the mating mechanism 11, thereby driving the first cleaning module 2 to swing relative to the device body 1 between the retracted position and the extended position.

[0051] Refer to Figures 3-5 , according to some embodiments of the present utility model, the first cleaning module 2 includes a transmission box 25. The drive motor 211 is disposed in the transmission box 25. The transmission assembly 212 and the mating mechanism 11 are both located in the transmission box 25. An installation shaft 113 is provided on the mating main body 111, and the installation shaft 113 is connected to the device body 1. An avoidance hole 251 for avoiding the installation shaft 113 is provided on the transmission box 25. The transmission assembly 212 and the mating mechanism 11 are located in the transmission box 25. The transmission box 25 can protect the transmission assembly 212 and the mating mechanism 11, and can reduce the possibility of damage to the transmission assembly 212 or the mating mechanism 11 due to external impact. The connection between the installation shaft 113 and the device body 1 can achieve the fixed connection between the mating main body 111 and the device body 1. The avoidance hole 251 can facilitate the installation of the mating main body 111 on the transmission box 25 and can make the overall structure of the mating mechanism 11 and the transmission box 25 compact.

[0052] Refer to Figures 3-5, according to some embodiments of the present utility model, the second transmission mechanism 215 includes a first transmission member 216, a transmission selection member 218 and a second transmission member 217. The first transmission member 216 meshes with the mating mechanism 11. The relative movement of the first transmission member 216 with respect to the mating mechanism 11 can drive the first cleaning module 2 to move between the retracted position and the extended position. The second transmission member 217 is drivably connected to the output end 214 of the drive motor 211, and the output end 214 of the drive motor 211 can drive the second transmission member 217 to move. The transmission selection member 218 is selectively drivably connected between the first transmission member 216 and the second transmission member 217. The second transmission member 217 can drive the transmission selection member 218 to move, and the transmission selection member 218 can drive the first transmission member 216 to move, so as to realize the drive motor 211 driving the first transmission member 216 to move. By selectively drivably connecting the transmission selection member 218 between the first transmission member 216 and the second transmission member 217, the on-off of the transmission path between the second transmission member 217 and the first transmission member 216 can be controlled, and thus the on-off of the transmission path between the drive motor 211 and the first transmission member 216 can be controlled.

[0053] Wherein, when the drive motor 211 rotates in the first direction, the transmission selection member 218 is in driving connection with both the first transmission member 216 and the second transmission member 217. At this time, the drive motor 211 can drive the second transmission member 217 to move. The movement of the second transmission member 217 can drive the transmission selection member 218 to move, and the transmission selection member 218 can drive the first transmission member 216 to move. By meshing the first transmission member 216 with the mating mechanism 11 and the mating mechanism 11 being fixed relative to the device body 1, the first transmission member 216 can move relative to the mating mechanism 11, thereby driving the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position; and, at this time, the rotation of the output end 214 of the drive motor 211 can also drive the first transmission mechanism 213 to move, and the movement of the first transmission mechanism 213 can also drive the cleaning component 23 to rotate about its own central axis.

[0054] When the drive motor 211 rotates in the second direction, the transmission selection member 218 is disengaged from driving connection with one of the first transmission member 216 and the second transmission member 217, and the second direction is opposite to the first direction. When the drive motor 211 rotates in the second direction, the transmission selection member 218 is disengaged from one of the first transmission member 216 and the second transmission member 217, so that the transmission path between the first transmission member 216 and the second transmission member 217 is disconnected. At this time, the drive motor 211 cannot drive the first cleaning module 2 to move between the retracted position and the extended position via the second transmission mechanism 215, and the drive motor 211 drives the cleaning component 23 to rotate about its own central axis to clean the working surface through the first transmission mechanism 213.

[0055] The transmission selection member 218 is selectively drivably connected between the first transmission member 216 and the second transmission member 217, and the on / off of the transmission path between the first transmission member 216 and the second transmission member 217 of the second transmission mechanism 215 can be controlled, so as to realize the control of the movement of the drive motor 211 between the retracted position and the extended position of the first cleaning module 2, so as to meet different cleaning requirements of the cleaning device 100.

[0056] Referring to Figures 3-5 , according to some embodiments of the present invention, the first transmission member 216 is a gear and the first transmission member 216 is sleeved on the outer peripheral side of the transmission selection member 218 and the first transmission member 216 is fixed relative to the transmission selection member 218. The transmission selection member 218 is fixedly connected to the first transmission member 216, and the rotation of the transmission selection member 218 can directly drive the first transmission member 216 to rotate. The second transmission member 217 is a gear. The second transmission member 217 includes a transmission tooth portion 219 and a matching portion 220 arranged along the axial direction of the second transmission member 217. The matching portion 220 is connected to the transmission tooth portion 219 and the matching portion 220 is relatively fixed to the transmission tooth portion 219. The transmission tooth portion 219 is drivably connected to the output end 214 of the drive motor 211, and the transmission selection member 218 is sleeved on the outer peripheral side of the matching portion 220. The transmission tooth portion 219 is drivably connected to the output end 214 of the drive motor 211. When the drive motor 211 works, the rotation of the output end 214 can drive the transmission tooth portion 219 to rotate, and the rotation of the transmission tooth portion 219 can directly drive the matching portion 220 to rotate, so as to realize the drivable connection between the drive motor 211 and the second transmission member 217. The transmission selection member 218 is sleeved on the outer peripheral side of the matching portion 220. The transmission selection member 218 can selectively drive the on / off of the transmission connection between the connecting member and the second transmission member 217, so as to control the on / off of the transmission path between the second transmission member 217 and the first transmission member 216.

[0057] When the drive motor 211 rotates in the first direction, the transmission selection member 218 is in drivable connection with the matching portion 220. At this time, the rotation of the output end 214 of the drive motor 211 can drive the transmission tooth portion 219 to rotate, the rotation of the transmission tooth portion 219 can drive the matching portion 220 to rotate, the rotation of the matching portion 220 can drive the transmission selection member 218 to rotate, and the rotation of the transmission selection member 218 can drive the first transmission member 216 to rotate. By meshing the first transmission member 216 with the matching mechanism 11 and the matching mechanism 11 is fixed relative to the device body 1, the first transmission member 216 can move relative to the matching mechanism 11, so as to drive the first cleaning module 2 to move between the retracted position and the extended position relative to the device body 1.

[0058] When the driving motor 211 rotates in the second direction, the transmission selection member 218 is disconnected from the mating portion 220. At this time, the transmission path between the second transmission member 217 and the first transmission member 216 is disconnected, and the driving motor 211 cannot drive the first cleaning module 2 to move between the retracted position and the extended position via the second transmission mechanism 215. The driving motor 211 drives the cleaning member 23 to rotate about its own central axis to clean the working surface via the first transmission mechanism 213.

[0059] Referring to Figure 3 and Figure 5 According to some embodiments of the present invention, the transmission selection member 218 is a one-way bearing. Through the one-way bearing, the connection and disconnection of the transmission between the transmission selection member 218 and the mating portion 220 can be realized. When the driving motor 211 rotates in the first direction, the one-way bearing is in transmission connection with the mating portion 220. At this time, the driving motor 211 can drive the cleaning member 23 to rotate about its own central axis to clean the working surface via the first transmission mechanism 213 and can drive the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position via the second transmission mechanism 215. When the driving motor 211 rotates in the second direction, the one-way bearing is disconnected from the mating portion 220. At this time, the transmission path between the second transmission member 217 and the first transmission member 216 is disconnected, and the driving motor 211 drives the cleaning member 23 to rotate about its own central axis to clean the working surface via the first transmission mechanism 213.

[0060] Referring to Figures 3-5 According to some embodiments of the present invention, the transmission assembly 212 includes a third transmission mechanism 221. The third transmission mechanism 221 is drivably connected to the output end 214 of the driving motor 211. When the driving motor 211 operates, the rotation of the output end 214 can drive the third transmission mechanism 221 to move. Both the first transmission mechanism 213 and the second transmission mechanism 215 are drivably connected to the third transmission mechanism 221. The movement of the third transmission mechanism can drive the movement of the first transmission mechanism 213 and the second transmission mechanism 215, so as to realize the driving motor 211 driving the first transmission mechanism 213 and the second transmission mechanism 215 to move, and further realize the driving motor 211 driving the cleaning member 23 to rotate about its own central axis to clean the working surface and driving the first cleaning module 2 to move relative to the device body 1 between the retracted position and the extended position.

[0061] Referring to Figures 3-5, according to some embodiments of the present utility model, the third transmission mechanism 221 is a gear transmission mechanism, and both the first transmission mechanism 213 and the second transmission mechanism 215 are engaged with the third transmission mechanism 221, which can realize the drivable connection between the third transmission mechanism 221 and the first transmission mechanism 213 and the second transmission mechanism 215, so as to realize the drivable connection between the driving motor 211 and the first transmission mechanism 213 and the second transmission mechanism 215.

[0062] Refer to Figures 3-5 , according to some embodiments of the present utility model, the cleaning device 100 includes an elastic member 3. The first cleaning module 2 includes a transmission box 25, and the driving motor 211 is installed in the transmission box 25. The transmission assembly 212 is located in the transmission box 25. One end of the elastic member 3 is connected to the transmission box 25, and the other end of the elastic member 3 is connected to the device body 1. The driving motor 211 is used to drive the first cleaning module 2 to move from the extended position to the retracted position, and the elastic member 3 is used to drive the first cleaning module 2 to move from the retracted position to the extended position. When the driving motor 211 stops working, the first cleaning module 2 moves from the extended position towards the direction close to the retracted position under the action of an obstacle outside the cleaning device 100. By providing the elastic member 3, the elastic member 3 provides a driving force so as to be able to drive the first cleaning module 2 to move from the retracted position to the extended position, so that the elastic member 3 can cooperate with the driving motor 211 to control the movement of the first cleaning module 2 between the retracted position and the extended position, so that the cleaning device 100 can realize the function of expanding the cleaning range.

[0063] For example, when the first cleaning module 2 moves from the retracted position to the extended position, the driving motor 211 can rotate in the second direction. At this time, the drivable connection between the transmission selection member 218 and the second transmission member 217 is disconnected, and the elastic member 3 can drive the first cleaning module 2 to move from the retracted position to the extended position.

[0064] For another example, when the first cleaning module 2 moves from the extended position to the retracted position, the driving motor 211 can rotate in the first direction. At this time, the transmission selection member 218 is in drivable connection with both the first transmission member 216 and the second transmission member 217. The driving motor 211 can drive the second transmission member 217 to move, the second transmission member 217 can drive the transmission selection member 218 to move, and the transmission selection member 218 can drive the first transmission member 216 to move, so as to drive the first cleaning module 2 to move from the extended position towards the retracted position.

[0065] Moreover, by providing the elastic member 3, when the driving motor 211 stops working and the cleaning device 100 hits an external obstacle, the first cleaning module 2 can move from the extended position towards the retracted position against the elastic force of the elastic member 3 under the action of the force exerted by the external obstacle, which can reduce or avoid the possibility of damage or jamming of the cleaning device 100. In addition, when the cleaning device 100 bypasses the obstacle, under the action of the elastic restoring force of the elastic member 3, the first cleaning module 2 can automatically return from the retracted position to the extended position. The provision of the elastic member 3 can also reduce or avoid changes in the body state or body position of the cleaning device 100 caused by the collision with the obstacle.

[0066] For example, when the cleaning device 100 needs to clean a corner, the driving motor 211 rotates in the second direction. At this time, the transmission connection between the transmission selector 218 and the second transmission member 217 is disconnected, and the elastic member 3 can drive the first cleaning module 2 to move from the retracted position to the extended position so that the first cleaning module 2 can clean the corner area; after the cleaning device 100 finishes cleaning the corner area, the driving motor 211 rotates in the first direction. At this time, the transmission selector 218 is in transmission connection with both the first transmission member 216 and the second transmission member 217. The driving motor 211 can drive the second transmission member 217 to move, the second transmission member 217 can drive the transmission selector 218 to move, and the transmission selector 218 can drive the first transmission member 216 to move, thereby driving the first cleaning module 2 to move from the extended position towards the retracted position.

[0067] Referring to Figure 1 and Figure 2 , according to some embodiments of the present invention, the elastic member 3 is a tension spring. One end of the tension spring is connected to the transmission case 25, and the other end of the tension spring is connected to the device body 1. When the first cleaning module 2 is in the retracted position, the tension spring is in a stretched state and stores energy. The device body 1 is fixedly arranged. In this way, the other end of the tension spring exerts an elastic restoring force on the transmission case 25. The first cleaning module 2 includes the transmission case 25, so that the tension spring can drive the movement of the first cleaning module 2.

[0068] Referring to Figure 1 and Figure 2 , according to some embodiments of the present invention, the first cleaning module 2 is a side brush module or a mopping module, and the first cleaning module 2 is adjacent to the outer periphery of the device body 1. By making the first cleaning module 2 a side brush module or a mopping module and the first cleaning module 2 adjacent to the outer periphery of the device body 1, the first cleaning module 2 can effectively clean narrow areas around walls, furniture feet or other obstacles, and is beneficial to expanding the cleaning range of the cleaning device 100.

[0069] Referring to Figure 1 and Figure 2, according to some embodiments of the present utility model, there are multiple first cleaning modules 2, and the multiple first cleaning modules 2 are arranged at intervals along the circumferential direction of the device body 1. By providing multiple first cleaning modules 2 arranged at intervals along the circumferential direction of the device body 1, it is beneficial to further increase the cleaning area of the first cleaning modules 2, thereby further improving the cleaning effect of the cleaning device 100.

[0070] In the description of the present utility model, "multiple" means two or more.

[0071] According to some embodiments of the present utility model, the cleaning device 100 further includes a second cleaning module installed on the device body 1. The second cleaning module is the main cleaning module and is arranged adjacent to the center of the device body 1. For example, the second cleaning module is a roller brush module. By providing the cleaning device 100 with a main cleaning module arranged adjacent to the center of the device body 1, the cleaning area coverage of the main cleaning module is relatively large, which is beneficial for the cleaning device 100 to efficiently clean the working surface.

[0072] According to some embodiments of the present utility model, the first cleaning modules 2 and the second cleaning module are arranged at intervals in the front-back direction. By arranging the first cleaning modules 2 and the second cleaning module at intervals in the front-back direction, it can avoid interference between the first cleaning modules 2 and the second cleaning module when cleaning the working surface, and at the same time is beneficial for achieving cleaning coverage of different areas of the working surface.

[0073] The following refers to Figures 1-5 Describe the cleaning device 100 according to some embodiments of the present utility model.

[0074] Refer to Figure 1 , Figure 3 and Figure 5 , in this embodiment, the cleaning device 100 includes a device body 1, a first cleaning module 2, a second cleaning module, and an elastic member 3.

The elastic member 3 is used to drive the first cleaning module 2 to move from the retracted position to the extended position.

[0076] The device body 1 is provided with a matching structure. The matching mechanism 11 is fixed relative to the device body 1. The matching mechanism 11 includes a matching main body 111 and a matching tooth part 112.

The driving motor 211 is installed in the transmission box 25. The transmission component 212 is located in the transmission box 25. One end of the elastic member 3 is connected to the transmission box 25. The driving motor 211 is used to drive the first cleaning module 2 to move from the extended position to the retracted position. When the driving motor 211 stops working, the first cleaning module 2 moves from the extended position towards the direction close to the retracted position under the action of the obstacles outside the cleaning device 100.

[0078] The transmission component 212 includes a first transmission mechanism 213, a second transmission mechanism 215 and a third transmission mechanism 221. The first transmission mechanism 213 is drivably connected between the output end 214 of the driving motor 211 and the cleaning component 23 to drive the cleaning component 23 to rotate around its own central axis. One end of the second transmission mechanism 215 is drivably connected to the output end 214 of the driving motor 211, and the other end of the second transmission mechanism 215 meshes with the matching tooth part 112 to drive the first cleaning module 2 to swing relative to the device body 1 between the retracted position and the extended position.

[0079] The second transmission mechanism 215 includes a first transmission member 216, a transmission selection member 218, and a second transmission member 217. The first transmission member 216 meshes with the mating mechanism 11. The second transmission member 217 is drivably connected to the output end 214 of the drive motor 211. The transmission selection member 218 is selectively drivably connected between the first transmission member 216 and the second transmission member 217.

The transmission tooth portion 219 is drivably connected to the output end 214 of the drive motor 211. The transmission selection member 218 is sleeved on the outer peripheral side of the mating portion 220.

[0080] Wherein, when the drive motor 211 rotates in the first direction, the transmission selection member 218 is in driving connection with the mating portion 220; when the drive motor 211 rotates in the second direction, the transmission selection member 218 is disconnected from the mating portion 220 in terms of driving connection.

[0081] The third transmission mechanism 221 is a gear transmission mechanism. The third transmission mechanism 221 is drivably connected to the output end 214 of the drive motor 211. Both the first transmission mechanism 213 and the second transmission mechanism 215 mesh with the third transmission mechanism 221.

[0082] For example, when the cleaning device 100 needs to clean a corner, the drive motor 211 rotates in the second direction. At this time, the driving connection between the transmission selection member 218 and the second transmission member 217 is disconnected, and the elastic member 3 can drive the first cleaning module 2 to move from the retracted position to the extended position so that the first cleaning module 2 can clean the corner area; after the cleaning device 100 finishes cleaning the corner area, the drive motor 211 rotates in the first direction. At this time, the transmission selection member 218 is in driving connection with both the first transmission member 216 and the second transmission member 217. The drive motor 211 can drive the second transmission member 217 to move. The second transmission member 217 can drive the transmission selection member 218 to move. The transmission selection member 218 can drive the first transmission member 216 to move, thereby driving the first cleaning module 2 to move from the extended position towards the retracted position.
