[0108] To solve the problem that the current cleaning device's roller 212 cannot clean the edge and the cleaning coverage is low, the first embodiment of the present application provides a cleaning device.

[0109] First, the directions mentioned in the following embodiments of the present application are described as follows:

[0110] First direction: The first direction is Figure 1 The direction indicated by the arrow X, that is, the moving direction of the cleaning part 21 of the cleaning device.

[0111] Second direction: The second direction is Figure 1 The direction indicated by the arrow Y.

[0112] Third direction: The third direction is Figure 2 The direction indicated by the arrow Z, that is, the height direction of the cleaning device.

[0113] Please refer to Figures 1 to 8 The cleaning device in the embodiment includes a body 10 and a cleaning mechanism 20. The body 10 is provided with a receiving cavity 11. In the first direction, at least one side of the receiving cavity 11 penetrates the outer peripheral edge of the body 10, and the outer peripheral edge of the body 10 has an apex 12 in the first direction, which is the end point of the outer peripheral edge of the body 10 closest to the blind area. The outer peripheral edge profile of the body 10 can include square, circular, oval, diamond, polygonal, and other special-shaped structures, etc. according to actual design requirements. Regardless of the shape of the body 10, the apex 12 is the end point of the outer peripheral edge of the body 10 closest to the equilateral corner area of the wall surface in the extension direction of the cleaning piece 21 (i.e. the first direction). When the outer peripheral edge profile of the body 10 is circular, the apex 12 is the end point of the outer peripheral edge of the circular body 10 in the first direction. The body 10 has a straight line 13 passing through the apex 12 and perpendicular to the first direction at the apex 12 of the outer peripheral edge of the body 10. When the outer peripheral edge profile of the body 10 is a circular profile, the straight line 13 includes the tangent line of the circular profile at the apex 12. When the outer peripheral edge profile of the body 10 is a rectangular profile, the straight line 13 coincides with one side of the rectangular profile in the first direction.

[0114] As shown in Figure 7 and Figure 8 The cleaning mechanism 20 includes a cleaning piece 21, a first driving assembly 22, and a connecting bracket 23. The connecting bracket 23 is installed in the receiving cavity 11 and can move relative to the body 10 in the first direction. The first driving assembly 22 is installed in the receiving cavity 11 and connected with the connecting bracket 23. The cleaning piece 21 is connected with the connecting bracket 23. The cleaning piece 21 has a first position that moves with the connecting bracket 23 in the first direction to exceed or flush with the straight line 13, and a second position that moves with the connecting bracket 23 to retract into the receiving cavity 11. The first driving assembly 22 drives the connecting bracket 23 to move the cleaning piece 21 between the first position and the second position.

[0115] When the cleaning device travels and moves to a blind area such as a corner of a wall, an edge of a wall, an edge of an obstacle, etc., the cleaning member 21 can be driven by the first driving assembly 22 to move to the first position in the first direction to extend out of the body 10 to abut against the blind area for edge cleaning. Since the cleaning member 21 in the first position is flush with or even beyond the straight line 13 passing through the apex 12 of the body 10, the part of the cleaning member 21 extending out of the body 10 can clean all areas between the peripheral edge of the body 10 and the wall surface, and there is no case that even if the cleaning member 21 extends out of the body 10, there is still a cleaning blind area between the body 10 and the wall surface, which improves the cleaning coverage of the cleaning device on the surface to be cleaned. When the cleaning device travels to a place without a blind area for cleaning, the cleaning member 21 can be driven by the first driving assembly 22 to retract into the receiving cavity 11 of the body 10. When the cleaning member 21 is a roller 212, the roller 212 retracted into the receiving cavity 11 cleans the surface to be cleaned along the travel path of the cleaning device, and when it encounters a corner area, the roller 212 is again driven by the first driving assembly 22 to move to the first position extending out of the body 10 for edge cleaning. Since the end of the roller 212 close to the wall surface in the first position is flush with or even beyond the straight line 13 passing through the apex 12 of the body 10, the roller 212 can fully clean the area between the peripheral edge of the body 10 and the wall surface, which improves the cleaning coverage of the roller 212.

[0116] It can be seen that the cleaning device provided in the embodiment includes the body 10 and the cleaning mechanism 20. The body 10 is provided with the receiving cavity 11. The peripheral edge of the body 10 has the apex 12 in the first direction. The apex 12 has the straight line 13 passing through the apex 12 and perpendicular to the first direction. The cleaning member 21 of the cleaning mechanism 20 has the first position moving along the first direction to be beyond or flush with the straight line 13. When the cleaning member 21 needs to clean a blind area, the first driving assembly 22 can drive the connecting bracket 23 to drive the cleaning member 21 to move to the first position. At this time, since the cleaning member 21 extends out of the body 10, the area between the cleaning member 21 and the peripheral edge of the body 10 can be cleaned without a cleaning blind area, which further improves the cleaning coverage of the cleaning member 21 on the surface to be cleaned when the cleaning member 21 performs edge cleaning on the blind area, reduces the blind area dead angle, achieves an ideal cleaning effect, and provides a good user experience. When edge cleaning is not needed, the first driving assembly 22 can drive the connecting bracket 23 to drive the cleaning member 21 to retract to the second position in the receiving cavity 11. That is, the first driving assembly 22 can flexibly switch the cleaning member 21 between the first position and the second position according to the environment of the surface to be cleaned, so as to improve the cleaning coverage of the cleaning member 21 on the surface to be cleaned.

[0117] In the second direction, the body 10 of the cleaning device includes a first end 101 and a second end 102, the distance between the cleaning member 21 and the first end 101 in the second direction is less than the distance between the cleaning member 21 and the second end 102 in the second direction, that is, the cleaning member 21 is located at the rear area of the body 10, so as to reserve sufficient installation space for the installation of corresponding devices for the positions of the body 10 except the area where the cleaning member 21 is located.

[0118] As shown in Figures 1 to 6 The body 10 of the cleaning device in the embodiment can include a mounting shell 15, a walking assembly 16, a clean water tank 30, a dirty water tank 40, an edge brush assembly 60, a dust box 70, and a middle sweeping assembly 80. The mounting shell 15 is the main frame of the cleaning device, the clean water tank 30 and the dirty water tank 40 are connected to the body 10 through the mounting shell 15, and the clean water tank 30 is located above the dirty water tank 40 in the third direction. The walking assembly 16 is arranged at the bottom of the mounting shell 15, and is used to drive the cleaning device to travel to the cleaning area for cleaning work. The clean water tank 30 is used to provide clean water to the cleaning member 21 to soak the cleaning member 21 and improve the cleaning effect of the cleaning member 21 on the surface to be cleaned. The clean water tank 30 is provided with a clean water injection port, which is communicated with the clean water bucket of the base station when the cleaning device enters the base station, so that the base station injects clean water into the clean water tank 30. The receiving cavity 11 is arranged at the bottom of the mounting shell 15, and the connecting bracket 23 can also be connected to a water scraping plate 50 for scraping water on the cleaning member 21. The dirty water tank 40 is located below the water scraping plate 50 to collect the dirty water scraped from the cleaning member 21 by the water scraping plate 50. The dirty water tank 40 is provided with a dirty water suction port 46 on one side, which is used to communicate with the dirty water bucket of the base station when the cleaning device enters the base station, so as to discharge the dirty water in the dirty water tank 40 into the dirty water bucket of the base station. The edge brush assembly 60 is one of the core components of the cleaning device, which can be installed at the edge position of the bottom of the mounting shell 15 to clean the blind area such as the corner and the wall edge which is usually ignored.

[0119] The middle sweeping assembly 80 in the embodiment is arranged at the bottom of the body 10, and the cleaning member 21 is located on one side of the middle sweeping assembly 80 in the second direction. The middle sweeping assembly 80 is the main sweeping component of the cleaning device, which is used to sweep the garbage on the travel path of the cleaning device into the dust box 70. The middle sweeping assembly 80 is usually located at the middle position of the bottom of the body 10, and then the cleaning member 2 is located at the position close to the rear of the body 10 on one side of the middle sweeping assembly 80, so that the cleaning member 2 can wet clean the area swept by the middle sweeping assembly 80 again.

[0120] Specifically, the middle sweeping assembly 80 of the cleaning device is arranged in the middle region of the bottom surface of the mounting shell 15, and the dust box 70 is arranged at a position close to the middle sweeping assembly 80 of the mounting shell 15. The body 10 is provided with a second vacuum pump 73 for performing negative pressure extraction on the dust box 70, so that the dust box 70 can suck and temporarily store the garbage swept by the middle sweeping assembly 80 and the brush assembly 60 through the negative pressure extraction of the dust box 70 by the second vacuum pump 73. Moreover, the bottom of the body 10 of the embodiment is further provided with a suction dust collection port 71 and a blowing dust collection port 72 which are in communication with the dust box 70. The base station is provided with a dust collection fan. After the cleaning device moves to the base station, the suction dust collection port 71 and the blowing dust collection port 72 are in communication with the dust collection fan, so as to recycle the garbage in the dust box 70 into the dust collection box of the base station. In addition, the body 10 is further provided with a return charging indicator 17, which is used to indicate the docking of the cleaning device and the base station, so as to return to the base station to perform charging, backwashing, dust collection and the like.

[0121] As shown in Figure 7 and Figure 8 The cleaning mechanism 20 provided by the embodiment further includes a mounting bracket 24. The mounting bracket 24 is installed in the receiving cavity 11, and the mounting bracket 24 is provided with a avoiding port 241 along the second direction. The connecting bracket 23 is installed on the mounting bracket 24 and can move along the first direction relative to the mounting bracket 24. The connecting bracket 23 is at least partially arranged on the avoiding port 241, and the first driving assembly 22 is installed on the mounting bracket 24 and connected with the connecting bracket 23 through the avoiding port 241. Specifically, the connecting bracket 23 includes a first bracket 231 and a second bracket 232. The first bracket 231 is connected with the mounting bracket 24 and can move along the first direction relative to the mounting bracket 24, and the first bracket 231 is at least partially arranged on the avoiding port 241. The first driving assembly 22 is installed on the mounting bracket 24 and connected with the part of the first bracket 231 exposed on the avoiding port 241. The second bracket 232 is connected with the first bracket 231 and the cleaning piece 21 and located between the first bracket 231 and the cleaning piece 21. When the first driving assembly 22 drives the first bracket 231 to move along the first direction, the first bracket 231 drives the cleaning piece 21 on the second bracket 232 to move along the first direction to the first position or the second position.

[0122] Therefore, the connecting bracket 23 is movably connected with the mounting bracket 24, so that the first driving assembly 22 can be mounted on the mounting bracket 24 and connected with the connecting bracket 23 through the avoiding opening 241 of the mounting bracket 24 to drive the connecting bracket 23 to move relative to the mounting bracket 24 in the first direction. After the cleaning member 21 is connected with the connecting bracket 23, the mounting bracket 24 is mounted in the receiving cavity 11, so that the cleaning member 21 is mounted in the receiving cavity 11 of the body 10, which is low in mounting difficulty and efficient in assembly. Moreover, the first driving assembly 22 is connected with the connecting bracket 23 through the avoiding opening 241 of the mounting bracket 24, which can not only reduce the assembly difficulty between the connecting bracket 23 and the first driving assembly 22, but also make the overall structure of the cleaning mechanism 20 more compact and reliable and save the mounting space. Meanwhile, the receiving cavity 11 of the body 10 can be correspondingly provided with a receiving groove for accommodating the first driving assembly 22, so that the first driving assembly 22 can be abutted in the receiving groove by the mounting bracket 24 when the mounting bracket 24 is mounted in the receiving cavity 11, which further improves the compactness and structural reliability between the cleaning mechanism 20 and the body 10.

[0123] Please refer to Figure 8 The first driving assembly 22 in the embodiment includes a first driving member 221, a first transmission member 222 and a second transmission member 223. The first driving member 221 is mounted on the mounting bracket 24. The first transmission member 222 is connected with the first driving member 221. The second transmission member 223 is located in the avoiding opening 241 and connected with the connecting bracket 23. The second transmission member 223 is in transmission connection with the first transmission member 222. The first driving member 221 drives the first transmission member 222 to drive the second transmission member 223 to move in the first direction.

[0124] In the process that the second transmission member 223 moves in the first direction, the cleaning member 21 connected with the connecting bracket 23 can be switched back and forth between the first position and the second position. When the cleaning device travels to a blind area such as a corner of a wall or furniture, the first driving member 221 drives the second transmission member 223 to drive the cleaning member 21 to move to the first position at the edge apex 12 of the body 10, so that the cleaning member 21 performs edge cleaning to improve the cleaning coverage of the cleaning device. When the cleaning device travels to a wider cleaning area, the first driving member 221 drives the second transmission member 223 to drive the cleaning member 21 to retract to the second position in the body 10, so that the cleaning member 21 cleans the cleaning surface on the travel path of the cleaning device. Therefore, the cleaning device in the embodiment can flexibly switch the cleaning member 21 between the first position and the second position through the first driving member 221 according to the environment of the cleaning surface, so as to improve the cleaning coverage of the cleaning device on the cleaning surface.

[0125] The first driving member 221 in the embodiment comprises a motor, the first transmission member 222 comprises a gear, and the second transmission member 223 comprises a rack. The gear is connected with the motor and can rotate along the circumferential direction of the gear under the driving of the motor. The rack is engaged with the gear. The length of the rack extends along the first direction. During the rotation of the gear driven by the motor, the rack can move along the first direction relative to the gear, and the rack can drive the cleaning member 21 on the connecting bracket 23 to move along the first direction to the first position or the second position. In addition, as shown in Figure 8 the length of the rack is less than the length of the avoiding opening 241 along the first direction, so as to ensure that the rack can drive the cleaning member 21 to switch between the first position and the second position along the first direction, and the avoiding opening 241 does not hinder the movement of the cleaning member 21 between the first position and the second position.

[0126] As shown in Figure 8 in order to prevent the cleaning member 21 from falling off the body 10 and even falling to the ground under the action of moving inertia during the movement of the cleaning member 21 to the first position, the cleaning mechanism 20 in the embodiment further comprises a limiting assembly 25 arranged between the connecting bracket 23 and the mounting bracket 24. The limiting assembly 25 is used to limit the cleaning member 21 at the first position when the cleaning member 21 moves to the first position, and the limiting assembly 25 is used to limit the cleaning member 21 at the second position when the cleaning member 21 moves to the second position, so as to stably keep the cleaning member 21 in the body 10. It can be seen that the embodiment can prevent the cleaning member 21 from falling off the body 10 due to moving inertia when reaching the first position, or prevent the cleaning member 21 from continuing to move under the action of moving inertia when reaching the second position, so as to stably and reliably keep the cleaning member 21 in the receiving cavity 11 of the body 10.

[0127] The limiting assembly 25 in the embodiment includes a first limiting member 251 and a second limiting member 252. The first limiting member 251 includes at least one, and the at least one first limiting member 251 is arranged on one of the connecting bracket 23 and the mounting bracket 24. The second limiting member 252 includes at least two, and the at least two second limiting members 252 are arranged on the other of the connecting bracket 23 and the mounting bracket 24 in the first direction. Wherein, in the second direction, the projection of the first limiting member 251 is located between the projections of the adjacent two second limiting members 252. In the first direction, the projection of the first limiting member 251 at least partially covers the second limiting member 252 and can move relative to the second limiting member 252 in the first direction, so that the first limiting member 251 can abut against the second limiting member 252 when moving in the first direction, thereby avoiding the cleaning piece 21 from continuing to move. When the first limiting member 251 moves in the first direction to abut against one of the second limiting members 252, the cleaning piece 21 will not continue to move, thereby limiting the cleaning piece 21 to the first position or the second position.

[0128] Specifically, the first limiting member 251 can be arranged on the side of the connecting bracket 23 close to the mounting bracket 24 and can move with the connecting bracket 23 in the first direction. When the connecting bracket 23 includes a first bracket 231 connected to the mounting bracket 24, the first limiting member 251 can be arranged on the side of the first bracket 231 close to the mounting bracket 24. The at least two second limiting members 252 are arranged on the side of the mounting bracket 24 close to the connecting bracket 23. Since the first limiting member 251 is located between the adjacent two second limiting members 252 arranged in the first direction, when the first limiting member 251 moves in the first direction to abut against any second limiting member 252, the cleaning piece 21 can be stopped from continuing to move in the first direction, thereby improving the assembly reliability between the cleaning piece 21 and the body 10 during movement. Moreover, when the first limiting member 251 abuts against the second limiting member 252, since the motor as the first driving member 221 can generate a large current due to the occurrence of the locked-rotor phenomenon. At this time, in order to avoid the energy consumption of the cleaning device caused by the long-term locked-rotor of the motor, and to avoid the performance reduction or damage caused by the long-term locked-rotor of the motor, the controller of the cleaning device can detect the current of the motor. When the current of the motor is greater than a predetermined value, the controller controls the motor to stop running. When the motor is started again, the controller controls the motor to rotate in the direction opposite to the last rotation direction (for example, the motor is forward rotated last time, and then the motor is reversed when started again), so as to drive the cleaning piece 21 to move reversely to the first position or the second position.

[0129] Before the motor in the embodiment stops running for the first time, the motor rotates in the forward direction, and when the motor stops running, the cleaning member 21 is in the first position. When the motor is started again, the motor is controlled to rotate in the reverse direction, and the cleaning member 21 will move in the reverse direction under the driving of the motor to the second position. When the cleaning member 21 moves to the second position, the first limiting member 251 abuts against another second limiting member 252 close to the second position, so as to avoid the cleaning member 21 from continuing to move and impacting or falling off the body 10. Similarly, when the cleaning member 21 is limited to the second position by the abutment of the first limiting member 251 and the second limiting member 252, the motor has a large starting current, and the controller controls the motor to stop rotating, so as to avoid long-term starting current of the motor to increase the energy consumption of the cleaning device and improve the service life of the motor.

[0130] To improve the stability of the cleaning member 21 during movement, the cleaning mechanism 20 in the embodiment further includes a guide assembly 26, which is arranged between the connecting bracket 23 and the mounting bracket 24 and is used to guide the connecting bracket 23 to stably move relative to the mounting bracket 24 in the first direction.

[0131] At least two second limiting members 252 in the embodiment are arranged on at least one side of the mounting bracket 24 in the third direction, and at least one first limiting member 251 is arranged on the connecting bracket 23 and located between the adjacent two second limiting members 252. The guide assembly 26 includes a guide shaft 261, the length of the guide shaft 261 extends in the first direction, the guide shaft 261 is arranged on at least one side of the mounting bracket 24 in the third direction and is fixedly connected with the second limiting member 252, and the first limiting member 251 is slidingly connected with the guide shaft 261.

[0132] Therefore, the embodiment connects the guide shaft 261 with the first limiting member 251 and the second limiting member 252, so as to movably mount the connecting bracket 23 on the mounting bracket 24 and guide the connecting bracket 23 to stably move in the first direction through the guide shaft 261. At the same time, when the connecting bracket 23 moves to drive the first limiting member 251 to move along the length direction of the guide shaft 261, the first limiting member 251 and the second limiting member 252 abut against each other to limit the cleaning member 21. It can be seen that the embodiment connects the connecting bracket 23 and the mounting bracket 24 through the guide shaft 261 to realize guidance and limit the movement distance of the cleaning member 21, so as to avoid the cleaning member 21 from falling off or impacting the body 10 due to excessive movement.

[0133] The guide shafts 261 in the embodiment can include at least two, and the at least two guide shafts 261 are respectively arranged on opposite sides of the mounting bracket 24 along the third direction, thereby improving the firmness and stability of the connecting structure between the mounting bracket 24 and the connecting bracket 23, and guiding the connecting bracket 23 to move more stably along the first direction relative to the mounting bracket 24 through the at least two guide shafts 261.

[0134] It can be seen that, in the embodiment, the guide shafts 261 are connected with the first limiters 251 arranged on the connecting bracket 23 and the second limiters 252 arranged on the mounting bracket 24, thereby not only improving the assembly efficiency between the connecting bracket 23 and the mounting bracket 24, but also ensuring that the connecting bracket 23 can move stably along the first direction relative to the mounting bracket 24. At the same time, the first limiters 251 can move with the connecting bracket 23, so that the first limiters 251 abut against the second limiters 252 on the mounting bracket 24, thereby accurately limiting the moving distance of the cleaning member 21, and further ensuring that the cleaning member 21 can accurately switch between the first position and the second position.

[0135] As shown in Figure 8 To further improve the accuracy and timeliness of controlling the operation of the motor, the limiting assembly 25 in the embodiment further includes a first limit switch 253 and a second limit switch 254. The first limit switch 253 is arranged on the mounting bracket 24 and located on one side of the avoiding opening 241 along the first direction. When the first limiter 251 contacts one of the two adjacent second limiters 252 to limit the cleaning member 21 to the first position, the second transmission member 223 contacts the first limit switch 253 to stop the first driving member 221 from working. Specifically, when the first limiter 251 abuts against the second limiter 252 adjacent to the first limit switch 253 among the two adjacent second limiters 252, the second transmission member 223 contacts the first limit switch 253 to trigger the first limit switch 253, and the motor stops operating when the first limit switch 253 is triggered, so that the cleaning member 21 stably docks at the first position for edge cleaning.

[0136] The second limit switch 254 in the embodiment is arranged on the mounting bracket 24 and located on the other side of the avoiding opening 241 along the first direction. When the first limit member 251 contacts the other one of the two adjacent second limit members 252 to limit the cleaning member 21 to the second position, the second transmission member 223 contacts the second limit switch 254 to stop the first driving member 221 from working. Specifically, during the process that the motor is started again to drive the cleaning member 21 to move to the second position, when the first limit member 251 contacts the second limit member 252 close to the second limit switch 254 among the two adjacent second limit members 252, the second transmission member 223 contacts the second limit switch 254 to trigger the second limit switch 254, and the motor stops working when the second limit switch 254 is triggered, so that the cleaning member 21 is stably parked at the second position for edge cleaning.

[0137] To ensure that the second transmission member 223 can timely and reliably trigger the first limit switch 253 or the second limit switch 254 when the cleaning member 21 is at the first position or the second position, in the embodiment, if the distance that the first limit member 251 moves along the first direction between the two adjacent second limit members 252 is a first distance, and the distance that the second transmission member 223 (which can be a rack in the embodiment) moves along the first direction between the first limit switch 253 and the second limit switch 254 is a second distance, the first distance is equal to the second distance, that is, when the first limit member 251 contacts the corresponding second limit member 252, the second transmission member 223 contacts the first limit switch 253 or the second limit switch 254 to trigger the motor to stop working.

[0138] The first limit switch 253 and the second limit switch 254 in the embodiment can include micro switches, position sensors, etc. The first limit switch 253 and the second limit switch 254 are preferably micro switches. A micro switch is a kind of switch with a small contact interval and a fast-moving mechanism, which performs switching action with a specified stroke and a specified force, and has a driving rod outside. Because the contact interval of the switch is relatively small, it is called a micro switch, also called a sensitive switch. The second transmission member 223 (such as a rack) can trigger the micro switch by using very small force to contact the micro switch, which has high sensitivity and timely control. Specifically, the motor and the micro switch can be connected to the controller of the cleaning device. The controller can control the motor to stop working in response to the information that the micro switch is triggered.

[0139] Of course, in some embodiments of the application, the motor can also be stopped by triggering the first limit switch 253 and the second limit switch 254 through the second transmission member 223 (e.g., a rack) alone, but in this way, if the first limit switch 253 and / or the second limit switch 254 (e.g., a micro switch) fails, not only can the motor not stop in time, but the cleaning member 21 can also not stop at the designated position, and the control risk is relatively high. In the present embodiment, the first limit member 251 and the second limit member 252 abut to limit the cleaning member 21 to the first position or the second position, so that even if the motor cannot stop in time, the movement stroke of the cleaning member 21 can still be ensured to exceed the predetermined range. Moreover, in the case where the motor is controlled to stop by detecting the change in motor current through the controller, the first limit switch 253 and the second limit switch 254 are added to further ensure that the motor can stop in time, and this double control method is more secure and reliable.

[0140] When the drum 212 and the support of the cleaning device need to be disassembled for cleaning and maintenance, due to the limitation of the installation method between the drum 212 and the support in the prior art, the cleaning device needs to be reversed to disassemble the drum 212, and the support cannot be disassembled from the cleaning device, so the user needs to manually hold the machine to clean the dirt inside the support, which brings great inconvenience to the user. For example, if the support connected to the drum 212 cannot be disassembled, since the driving motor 112 that drives the drum 212 to rotate is built-in the inner cavity of the drum 212, when the support is cleaned directly on the cleaning device, the driving motor 112 in the drum 212 may be wetted and damaged by water. To this end, the body 10 provided in the present embodiment has an opening 14 on at least one side of the receiving cavity 11 in the first direction, i.e., the opening 14 communicates with the receiving cavity 11 and is located on at least one side of the receiving cavity 11 in the first direction. The opening 14 is located at the side of the body 10 in the first direction. The connecting support 23 includes a first support 231 and a second support 232. The first support 231 is installed in the receiving cavity 11 and can move relative to the body 10 in the first direction. The second support 232 is detachably connected to the first support 231 and can move relative to the first support 231 in the first direction to be taken out from the opening 14. The cleaning member 21 is detachably connected to the second support 232 and can move relative to the second support 232 in the first direction to be taken out from the opening 14.

[0141] The cleaning element 21 in the embodiment can include a roller 212, and when the roller 212 needs to be cleaned, the cleaning element 21 (such as the roller 212) can be pulled out from the opening 14 along the first direction for cleaning and maintenance. In addition, the second support 232 close to the cleaning element 21 is easy to be contaminated, and when the second support 232 needs to be cleaned, the second support 232 can be pulled out from the opening 14 along the first direction for cleaning without reversing the body 10 or holding the heavy body 10 for cleaning the second support 232, which is convenient and time-saving. After the cleaning element 21 and the second support 232 are cleaned, the second support 232 is first moved to the position connected with the first support 231 along the first direction from the opening 14, and then the cleaning element 21 is moved to the position connected with the second support 232 along the first direction from the opening 14. In addition, the cleaning element 21 can be first connected with the second support 232 as a whole, and then the second support 232 connected with the cleaning element 21 is moved to the position connected with the first support 231 along the first direction, which improves the assembly efficiency and convenience of the cleaning element 21 and the second support 232 when they are installed in the body 10.

[0142] It can be seen that the body 10 of the cleaning device provided by the application is provided with the opening 14 and the receiving cavity 11, the opening 14 is in communication with the receiving cavity 11 and is located on at least one side of the receiving cavity 11 along the first direction. The cleaning element 21 and the second support 232 of the cleaning device are detachably connected and can move relative to the second support 232 along the first direction to be taken out from the opening 14, and the second support 232 is detachably installed in the receiving cavity 11 and can move relative to the body 10 along the first direction to be taken out from the opening 14. Specifically, the first support 231 is installed in the receiving cavity 11, and the second support 232 is detachably connected with the first support 231 and can move relative to the first support 231 along the first direction to be taken out from the opening 14. That is, the cleaning element 21 and the second support 232 close to the cleaning element 21 in the application can be respectively taken out from the opening 14 of the body 10 without reversing the machine body 10, which is simple in operation and time-saving and labor-saving to clean and maintain the taken-out cleaning element 21 and the second support 232 respectively.

[0143] When the cleaning element 21 and the second support 232 are disassembled, the cleaning element 21 can be first taken out from the opening 14, and then the second support 232 is taken out from the opening. Or the second support 232 can be first taken out from the opening, and then the cleaning element 21 is taken out from the opening 14. Or the second support 232 and the cleaning element 21 can be taken out from the opening 14 together, and then the cleaning element 21 is separated from the second support 232 when the second support 232 and the cleaning element 21 need to be cleaned respectively. In this regard, the extraction mode of the cleaning element 21 and the second support 232 can be determined according to the actual operation requirement, which is not limited in the embodiment.

[0144] like Figures 11 to 15 As shown, the second bracket 232 in this embodiment is provided with a first sliding space 2321, and the cleaning component 21 can slide within the first sliding space 2321 along a first direction. A first engaging portion 2322 is provided on either the body 10 (specifically, the first bracket 231 within the body 10) or the second bracket 232. The cleaning mechanism 20 in this embodiment also includes a first locking member 27, which is located at the end of the cleaning component 21 near the opening 14. The first locking member 27 has a first locking position that engages with the first engaging portion 2322 under external force and a first unlocking position that separates from the first engaging portion 2322.

[0145] The first locking member 27 in this embodiment can reliably lock the cleaning component 21 within the first sliding space 2321, ensuring that the cleaning component 21 will not fall off the main body 10 during normal operation of the cleaning device. Furthermore, by unlocking the first locking member 27, the cleaning component 21 can be separated from the first support 231 and the second support 232, allowing it to be easily and quickly extracted from the first sliding space 2321 from the opening 14 along the first direction without reversing the main body 10. If the cleaning component 21 includes a roller 212, the first locking member 27 can be positioned at the end of the roller 212 near the opening 14, locking the roller 212 within the first sliding space 2321. When it is necessary to remove the roller 212, unlocking the first locking member 27 allows the roller 212 to be extracted from the first sliding space 2321 through the opening 14.

[0146] Preferably, the first engaging portion 2322 is located at the end of the second bracket 232 near the opening 14. Thus, when the cleaning component 21 is pulled out from the opening along with the second bracket 232, the cleaning component 21 can be secured to the second bracket 232 by engaging the first engaging portion 232 with the first locking member 27, preventing it from falling off and being damaged. Simultaneously, after cleaning the cleaning component 21 and the second bracket 232 separately, the cleaning component 21 can be first engaged with the first engaging portion 2322 on the second bracket 232 via the first locking member 27, thus assembling the cleaning component 21 and the second bracket 232 as a single unit. Then, the second bracket 232 and the cleaning component 21 can be moved together from the opening along the first direction to the position within the storage cavity 11. Compared to installing the second bracket 232 and the cleaning component 21 separately, assembling the second bracket 232 and the cleaning component 21 together within the main body 10 is more efficient and convenient.

[0147] Further, since the first locking member 27 is located at the end of the cleaning member 21 close to the opening 14 of the body 10, the operator can easily unlock the first locking member 27 and unlock the first locking member 27 to the first unlocking position separated from the first clamping portion 2322. Since the cleaning member 21 can slide in the first sliding space 2321 relative to the second support 232 in the first direction, only the unlocking operation of the first locking member 27 is required to extract the cleaning member 21 in the first sliding space 2321 from the opening 14, which can reduce the operation force required when the cleaning member 21 is extracted and installed. When the second support 232 is a plastic support formed by injection molding, even if the plastic support deforms to a certain extent, the cleaning member 21 can be smoothly extracted from the first sliding space 2321 without using a large force.

[0148] As shown in Figure 9 、 Figures 16 to 23 , the first locking member 27 in the embodiment includes a first locking body 271, a first locking component 272, and a pop-up component 273. The first locking component 272 is movably connected to the first locking body 271 to be buckled with the first clamping portion 2322, and the first locking component 272 can be switched between the first locking position and the first unlocking position under the action of an external force. When the cleaning member 21 needs to be extracted from the body 10 for cleaning and maintenance, a certain force can be applied to the first locking component 272 to separate the first locking component 272 from the first clamping portion 2322, thereby pulling the cleaning member 21 out of the first sliding space 2321. When the cleaning member 21 needs to be installed in the first sliding space 2321, the cleaning member 21 is slid in the first direction into the first sliding space 2321, and a certain force is applied to the first locking component 272 to buckle the first locking component 272 with the first clamping portion 2322, so that the cleaning member 21 can be stably locked in the first sliding space 2321, avoiding the cleaning member 21 from sliding relative to the second support 232 or even falling down during the cleaning process, and improving the cleaning effect of the cleaning member 21 on the surface to be cleaned.

[0149] The ejecting component 273 of the first locking member 27 is arranged between the first locking main body 271 and the cleaning member 21, and is configured to apply an elastic force to the first locking main body 271 to automatically deviate the first locking member 27 from the first clamping portion 2322 when the first locking component 272 is in the first unlocking position. That is, when the first locking component 272 is in the first unlocking position, the first locking member 27 can be automatically deviated from the first clamping portion 2322 under the action of the ejecting component 273, which not only facilitates the operator to conveniently take out the cleaning member 21 by grabbing the first locking member 27, but also avoids the first locking component 272 from being mistakenly buckled with the first clamping portion 2322 again, thereby affecting the taking-out operation of the cleaning member 21 and improving the taking-out efficiency and operation convenience of the cleaning member 21.

[0150] In combination Figure 8 and Figure 16 It can be seen that the first locking main body 271 in the embodiment is provided with a first mounting space 2711 on the side close to the first clamping portion 2322, and the first mounting space 2711 includes a first notch 7111 close to the first clamping portion 2322. Specifically, the first locking component 272 includes a first elastic element 2721, a first buckling portion 2722, and a pushing element 2723. One end of the first elastic element 2721 is connected to the side of the first mounting space 2711 away from the first notch 7111. The first buckling portion 2722 is connected to the end of the first elastic element 2721 close to the first notch 7111, and the first buckling portion 2722 can at least partially protrude out of the first notch 7111 to be buckled with the first clamping portion 2322 under the elastic force of the first elastic element 2721. The pushing element 2723 is connected to the first buckling portion 2722, and the pushing element 2723 is configured to push the first buckling portion 2722 away from the first clamping portion 2322 against the elastic force of the first elastic element 2721.

[0151] When it is needed to lock the cleaning member 21 in the first sliding space 2321, the first buckling part 2722 can be at least partially extended out of the first slot 7111 and buckled with the first clamping part 2322 in the first locking position under the elastic force of the first elastic element 2721. When it is needed to take out the cleaning member 21 from the first sliding space 2321, the pushing element 2723 can be pushed in the compression direction of the first elastic element 2721 until the pushing element 2723 drives the first buckling part 2722 to move to the first unlocking position away from the first clamping part 2322, which is simple and convenient. Of course, when the first buckling part 2722 is in the first unlocking position, although the cleaning member 21 can be pulled out of the first sliding space 2321 in the first direction at this time, if the pushing element 2723 is not loosened accidentally, the first buckling part 2722 can be buckled with the first clamping part 2322 again under the elastic force of the first elastic element 2721. In this regard, since the ejection part 273 provided in the embodiment applies an elastic force to the first locking body 271, when the first buckling part 2722 is in the first unlocking position, the first locking part 272 will be elastically separated from the first locking body 271 to a position deviating from the first clamping part 2322 under the elastic force of the ejection part 273, so that the first locking part 272 and the first locking body 271 have a certain distance from the first support 231 and the second support 232. Even if the pushing element 2723 is loosened for extraction of the cleaning member 21, the first buckling part 2722 will not return to the first locking position, so that the first locking part 272 is convenient to hold the cleaning member 21 to be extracted.

[0152] As shown in Figure 15 the first mounting space 2711 on the first locking body 271 also includes a second slot 7112, which is located on the side of the first slot 7111 away from the first clamping part 2322 and on the side of the first locking body 271 close to the opening 14 of the body 10. As shown in Figure 19As shown, the toggle element 2723 in the embodiment includes a connecting block 7231 and a toggle block 7232. The connecting block 7231 is located in the first mounting space 2711 and connected with the first buckling part 2722. The toggle block 7232 is connected with the connecting block 7231 and located outside the second slot 7112, and the toggle block 7232 is used to toggle the first buckling part 2722 to move in the first elastic element 2721 in the compression direction, so as to move the first buckling part 2722 to the first unlocking position separated from the first clamping part 2322. Since the toggle block 7232 is located outside the second slot 7112 and close to the opening 14, it is convenient for the operator to toggle the toggle block 7232 to separate the cleaning element 21 from the first support 231 and the second support 232, so as to perform the extraction operation of the cleaning element 21. The outer surfaces of the connecting block 7231 and the toggle block 7232 away from the first mounting space 2711 are provided with a plurality of convex points, which can increase the friction when the hand touches the connecting block 7231 and the toggle block 7232, so as to facilitate the toggle of the toggle element 2723.

[0153] Specifically, in combination with Figure 10 、 Figure 17 It can be seen that, in the embodiment, the first recess 2323 is arranged on the side of the second support 232 close to the first locking member 272, and the first clamping part 2322 is arranged in the first recess 2323. The first lock body 271 includes a connecting plate 2712 and a mounting cover 2713. One side of the connecting plate 2712 is connected with the cleaning element 21, and the other side of the connecting plate 2712 is arranged opposite to the second support 232. The mounting cover 2713 is buckled on the side of the connecting plate 2712 opposite to the second support 232 and forms the first mounting space 2711 with the connecting plate 2712, and the shape of the mounting cover 2713 is matched with the inner wall surface of the first recess 2323. Therefore, when the first locking member 272 is buckled with the first clamping part 2322 on the second support 232 to lock the cleaning element 21 in the first sliding space 2321, the mounting cover 2713 where the first mounting space 2711 is located can be embedded in the first recess 2323, so as to buckle the first buckling part 2722 of the first locking member 272 with the first clamping part 2322 in the first recess 2323. This not only makes the assembly structure between the cleaning element 21 and the second support 232 more compact and stable, but also reduces the distance between the cleaning element 21 and the corner area of the wall, thereby further improving the cleaning coverage rate when the cleaning element 21 extends out of the body 10 to clean along the edge.

[0154] In the embodiment, one of the first clamping part 2322 and the first buckling part 2722 can include a convex structure, and the other one can include a recess structure. In this regard, the shape of the first clamping part 2322 and the first buckling part 2722 can be specifically set according to the actual design requirements, which is not uniquely limited in the embodiment. In a specific embodiment of the present application, as shown inFigure 10 As shown, the first engaging portion 2322 can include a first buckling groove 3221, and the first buckling portion 2722 can include a buckling block 7221 and a buckling tongue 7222. The buckling block 7221 is located in the first mounting space 2711 and connected with the first elastic element 2721 and the pushing element 2723. The size of the buckling block 7221 is greater than that of the first slot 7111, so as to limit the buckling block 7221 in the first mounting space 2711 and avoid increasing the buckling operation difficulty due to the extension of the buckling block 7221 out of the first mounting space 2711. The buckling tongue 7222 is located on the side of the buckling block 7221 close to the first slot 7111 and arranged opposite to the first slot 7111. The size of the buckling tongue 7222 is smaller than that of the first slot 7111 and matched with the first buckling groove 3221, so that the buckling tongue 7222 can be pushed by the buckling block 7221 to the first locking position of being buckled in the first buckling groove 3221 under the elastic force of the first elastic element 2721. When it is needed to unlock the cleaning piece 21 for extraction, the buckling tongue 7222 can be separated from the first buckling groove 3221 by pushing the pushing element 2723 in the direction away from the first buckling groove 3221. The buckling mode of inserting the buckling tongue 7222 into the first buckling groove 3221 in the present embodiment not only is convenient to operate, but also is easy to process, so as to reduce the assembly difficulty between the cleaning piece 21 and the second support 232. The first elastic element 2721 in the present embodiment is preferably a compression spring, which is cheap and easy to install.

[0155] As Figure 21 and Figure 22As shown, the ejecting component 273 in the embodiment includes a connecting body 2731, a connecting shaft 2732, and a second elastic element 2733. The connecting body 2731 is connected with the cleaning member 21. The connecting shaft 2732 is installed on the connecting body 2731. The first locking body 271 is connected with the connecting shaft 2732 and can rotate around the axis of the connecting shaft 2732. The second elastic element 2733 is connected between the connecting body 2731 and the first locking body 271. When it is needed to lock the cleaning member 21 in the first sliding space 2321 by the first locking member 27, the first locking body 271 can be pushed to rotate around the axis of the connecting shaft 2732 against the elastic force of the second elastic element 2733 to approach the first groove 2323 until the mounting cover 2713 of the first locking body 271 is located in the first groove 2323 and the first buckling part 2722 is buckled with the first clamping part 2322. When it is needed to extract the cleaning member 21, the pushing element 2723 is pushed in the compression direction of the first elastic element 2721 to separate the first buckling part 2722 from the first clamping part 2322, and the first locking body 271 can rotate around the axis of the connecting shaft 2732 to a position away from the second support 232 under the elastic force of the second elastic element 2733. At this time, the operator can take the first locking body 271 to extract the cleaning member 21 from the first sliding space 2321 in the first direction. The operation is simple and convenient, and the hand of the operator does not need to be deep into the storage cavity 11 to grasp the cleaning member 21 to take out the cleaning member 21.

[0156] The second elastic element 2733 can include a torsion spring (as shown). Figure 22 The torsion spring is sleeved on the connecting shaft 2732 and abuts between the connecting body 2731 and the first locking body 271 to pop the first locking body 271 away from the second support 232 by the torsion spring. In order to improve the connection reliability between the torsion spring and the connecting body 2731 and the first locking body 271, avoid the torsion spring from being separated from the original position under the elastic force of itself after being popped to affect the secondary locking of the cleaning member 21, a first connecting hole 7311 is arranged on the end of the connecting body 2731 close to the connecting shaft 2732, and one end of the torsion spring is fixed in the first connecting hole 7311 to avoid the torsion spring from sliding along the axis of the connecting shaft 2732 to other positions where the connecting body 2731 and the first locking body 271 are difficult to be simultaneously abutted.

[0157] Specifically, as shown in the following table, the first locking body 271 can be rotated around the axis of the connecting shaft 2732 to a position away from the second support 232 under the elastic force of the second elastic element 2733. Figures 11 to 15As shown, the cleaning member 21 in the embodiment comprises a driving component 211 and a roller 212. Specifically, the driving component 211 is fixed to one end of the first support 231 in the first direction within the body 10 and located in the first sliding space 2321 (i.e. on the side of the second support 232 away from the first support 231). The roller 212 is detachably sleeved on the driving component 211 and can rotate around its own axis under the driving of the driving component 211. The driving component 211 in the embodiment can comprise a mounting seat 111, a driving motor 112, a second bearing 113 and a connecting head 114. The mounting seat 111 is fixedly connected to the end of the first support 231 away from the first locking piece 27 of the cleaning member 21, the driving motor 112 is connected to the mounting seat 111, the connecting head 114 is connected to the rotating shaft of the driving motor 112, and the second bearing 113 is sleeved on the mounting seat 111 and located on the side of the driving motor 112 away from the connecting head 114 in the first direction. The roller 212 is provided with a connecting structure (such as a groove and / or a protrusion, etc.) matched with the connecting head 114, the roller 212 is movably sleeved on the driving component 211 (at this time, the second bearing 113, the driving motor 112 and the connecting head 114 are all located in the roller 212), and the driving motor 112 rotates to drive the roller 212 to rotate around its own axis through the connecting head 114, so that the roller 212 can realize efficient cleaning of the surface to be cleaned in the rotating process.

[0158] As shown, Figure 16 The first locking piece 27 in the embodiment further comprises a supporting component 274, which is arranged in the roller 212 and located at the end of the roller 212 away from the driving component 211 in the first direction. The supporting component 274 is connected with the connecting body 2731 and can rotate around the axis of the roller 212 relative to the connecting body 2731, so that the first locking body 271 connected with the connecting body 2731 will not interfere with the rotating movement of the roller 212. At the same time, the supporting component 274 and the driving component 211 are arranged in the opposite ends of the roller 212 along the length direction of the roller 212 to support the opposite ends of the roller 212, so that the opposite ends of the roller 212 in the first direction are not in a suspended state, which can improve the stability of the roller 212 in the rotating and moving process.

[0159] Specifically, as shown, Figure 21 and Figure 23As shown, the second recess 2741 is arranged on one side of the support component 274 close to the connecting body 2731, and the connecting body 2731 is arranged in the second recess 2741 and rotationally connected with the support component 274. Since the connecting body 2731 can rotate relative to the support component 274, the support component 274 connected with the connecting body 2731 can rotate with the roller 212 during the rotation of the roller 212, so as not to interfere with the rotation of the roller 212, and improve the stability of the roller 212 during movement and / or rolling. Moreover, since the connecting body 2731 is arranged in the second recess 2741 of the support component 274, the structure of the entire first locking member 27 is more compact and reliable. Moreover, when the support component 274 is arranged in the roller 212 to support the roller 212, the connecting body 2731 of the first locking member 27 does not increase the distance between the roller 212 and the wall surface along the first direction, so as to support the roller 212 by the support component 274 while reducing the cleaning blind area, so that the roller 212 can clean along the edge, and improve the cleaning coverage of the roller 212.

[0160] As shown in Figure 22 , the connecting body 2731 is provided with a third recess 7312 away from one side of the first locking body 271. As shown in Figure 23 , the support component 274 includes a support body 2742, a protruding column 2743 and a first bearing 2744. The support body 2742 is arranged in the roller 212 and abuts against the inner wall surface of the roller 212, and the second recess 2741 is arranged on one side of the support body 2742 close to the connecting body 2731. The support body 2742 can include a cylindrical structure, a prism structure, and specifically can include a cylindrical structure matched with the inner wall surface of the roller 212, so as to arrange the support body 2742 in the roller 212 to support the roller 212 while avoiding interference with the rotation of the roller 212 when the first locking member 27 is buckled with the second bracket 232. The protruding column 2743 is arranged at the bottom of the second recess 2741 in the support body 2742. The inner periphery of the first bearing 2744 is fixed on the protruding column 2743 and located in the third recess 7312, and the outer periphery of the first bearing 2744 is connected with the inner wall surface of the third recess 7312. During the rotation of the roller 212, the roller 212 will drive the support body 2742 to rotate, and since the connecting body 2731 is rotationally connected with the support body 2742 by the first bearing 2744, the first locking body 271 connected with the connecting body 2731 will not interfere with the rotational movement of the roller 212.

[0161] As shown in Figure 12 and Figure 15As shown, the first support 231 in the embodiment is installed in the receiving cavity 11 through the installation support 24, and the first support 231 is provided with a second sliding space 2311, and the second support 232 can slide in the first direction in the second sliding space 2311. For this purpose, in order to improve the stability of the second support 232 after being slidably installed in the second sliding space 2311, the cleaning mechanism 20 provided in the embodiment further comprises a sliding connection assembly 28, which is arranged between the first support 231 and the second support 232. The second support 232 has a first sliding position connected to the second sliding space 2311 through the sliding connection assembly 28 under the action of an external force, and a second sliding position separated from the first support 231.

[0162] It can be seen that the second support 232 can be slidably installed in the second sliding space 2311 of the first support 231 through the sliding connection assembly 28. When it is necessary to take out the second support 232 for cleaning and maintenance, the second support 232 is pulled out of the body 10 at the opening 14 of the first support 231 in the first direction. When it is necessary to install the second support 232 back into the second sliding space 2311, the second support 232 is pushed into the second sliding space 2311 in the first direction and connected to the first sliding position in the second sliding space 2311 through the sliding connection assembly 28. It can be seen that the second support 232 is slidably connected to the second sliding space 2311 through the sliding connection assembly 28, which improves the convenience of extracting and installing the second support 232.

[0163] The sliding connection assembly 28 comprises a sliding groove 281 and a sliding boss 282. The sliding groove 281 is arranged on at least one side of the second sliding space 2311 in the third direction. The sliding boss 282 is arranged on the side of the second support 232 close to the first support 231 and corresponds to the sliding groove 281. Thus, when the second support 232 is installed into the second sliding space 2311, the sliding boss 282 is slidably inserted into the sliding groove 281 in the second sliding space 2311. When it is necessary to extract the second support 232, the second support 232 is pulled in the first direction until the sliding boss 282 is separated from the sliding groove 281. Of course, the sliding groove 281 in the embodiment can also be arranged on the side of the second support 232 close to the first support 231, and the sliding boss 282 is arranged in the second sliding space 2311, or the sliding boss 282 and the sliding groove 281 can be arranged on the second support 232 and the first support 231 respectively, so as to stably slidably connect the second support 232 to the second sliding space 2311.

[0164] In another embodiment of the present application, regardless of whether the cleaning member 21 can be extracted from the opening 14 of the body 10, the second bracket 232 can be extracted from the side of the body 10 without turning over the cleaning machine, thereby solving the problem that the garbage on the bracket cannot be cleaned completely because the bracket cannot be detached from the cleaning machine in the prior art.

[0165] In order to enable the second bracket 232 to be extracted alone, the cleaning device in the embodiment includes the body 10 and the cleaning mechanism 20. The body 10 is provided with the opening 14 and the receiving cavity 11. The opening 14 is in communication with the receiving cavity 11 and is located on at least one side of the receiving cavity 11 along the first direction. The cleaning mechanism 20 includes the cleaning member 21 and the second bracket 232. The cleaning member 21 is installed in the receiving cavity 11 and forms the second sliding space 2311 together with the body 10. The second bracket 232 is detachably connected with the body 10 and is located in the second sliding space 2311. The second bracket 232 can slide in the second sliding space 2311 along the first direction to be extracted from the opening 14.

[0166] It can be seen that, because the cleaning member 21 is installed in the receiving cavity 11 and forms the second sliding space 2311 together with the body 10, the second bracket 232 is detachably connected with the body 10 and is located in the second sliding space 2311. The second bracket 232 can slide in the second sliding space 2311 along the first direction to be extracted from the opening. That is, the second bracket 232 in the embodiment can be extracted from the opening of the body 10 without turning over the body 10, which is simple in operation, time-saving and labor-saving, facilitates cleaning and maintenance of the extracted second bracket 232, and ensures that the garbage on the second bracket 232 can be completely cleaned.

[0167] In order to further improve the stability of the second bracket 232 relative to the first bracket 231 when the second bracket 232 is connected in the second sliding space 2311 and avoid the second bracket 232 from being separated from the first bracket 231 under the action of an external force, the first bracket 231 of the body 10 is further provided with a second clamping portion in the embodiment. Figure 12 、 Figures 24 to 26 As shown in FIGS. 8 and 9, the cleaning mechanism 20 further includes a second locking member 29. The second locking member 29 is arranged at one end of the second bracket 232 close to the opening 14. The second locking member 29 has a second locking position at which the second locking member 29 is clamped with the second clamping portion under the action of an external force and a second unlocking position at which the second locking member 29 is separated from the second clamping portion. Thus, when the second bracket 232 is connected in the second sliding space 2311, the second bracket 232 can be fixed with the first bracket 231 by the second locking member 29, thereby avoiding the second bracket 232 from sliding off the first bracket 231.

[0168] It can be seen that the second locking member 29 arranged on the second bracket 232 can stably and reliably lock the second bracket 232 in the second sliding space 2311, so as to ensure that the second bracket 232 connected with the cleaning member 21 will not fall off the body 10 during normal operation of the cleaning device, and improve the stability and firmness of the connection between the second bracket 232 and the first bracket 231. When the second bracket 232 needs to be taken out, the second locking member 29 can be unlocked to separate the second bracket 232 from the first bracket 231, so as to extract the second bracket 232 from the second sliding space 2311 along the first direction from the opening 14. Therefore, the second bracket 232 can be conveniently and quickly extracted in the lateral direction without reversing the body 10.

[0169] Secondly, since the second locking member 29 is located at the end of the second bracket 232 close to the opening 14 of the body 10, the operator can conveniently unlock the first locking member 27 to unlock the second locking member 29 to the second unlocking position away from the second clamping part. Moreover, since the second bracket 232 can slide relative to the first bracket 231 in the first direction in the second sliding space 2311, after unlocking the second locking member 29, the second bracket 232 located in the second sliding space 2311 can be extracted from the opening 14, thereby improving the convenience of taking out and installing the second bracket 232.

[0170] Specifically, in the cleaning mechanism 20 in the embodiment, the first bracket 231 is installed in the receiving cavity 11, the cleaning member 21 is connected with the first bracket 231 through the driving member 211 and surrounds the first bracket 231 to form the second sliding space 2311, the second clamping part is arranged on the first bracket 231, and the second bracket 232 is buckled with the second clamping part through the second locking member 29 to be locked in the second sliding space 2311. Therefore, when the second bracket 232 is taken out and cleaned, and then the second bracket 232 is slid in the first direction into the second sliding space 2311, the second bracket 232 is firmly and reliably retained in the second sliding space 2311 by buckling the second clamping part on the first bracket 231 through the second locking member 29, so that the second bracket 232 is not easy to slide out of the second sliding space 2311.

[0171] The second locking member 29 in the embodiment comprises a second locking body 291 and a second clasp 292. The second clasp 292 is movably connected to the second locking body 291 to be clasped with the second engaging portion, and the second clasp 292 can be switched between the second locking position and the second unlocking position under the action of external force. When the second support 232 needs to be extracted from the body 10 for cleaning and maintenance, a certain force can be applied to the second clasp 292 to separate the second clasp 292 from the second engaging portion, so as to pull out the second support 232 from the second sliding space 2311. When the second support 232 needs to be installed in the second sliding space 2311, after the second support 232 is slid along the first direction to be connected to the second sliding space 2311 through the sliding connection assembly 28, a certain force is applied to the second clasp 292 to clasp the second clasp 292 with the second engaging portion, so that the second support 232 can be stably locked in the second sliding space 2311, avoiding the second support 232 from sliding or even falling down during the cleaning work of the cleaning member 21, and improving the firmness and stability of the connection between the second support 232 and the first support 231.

[0172] As shown in Figure 10 , one end of the second support 232 close to the opening 14 is provided with a fourth groove 2324, and the fourth groove 2324 is located in the second direction opposite to the first support 231. As shown in Figures 24 to 26 , the second locking body 291 is installed in the fourth groove 2324, so as to avoid increasing the installation space between the first support 231 and the second support 232 due to the existence of the second locking body 291, making the overall structure of the cleaning mechanism 20 installed in the receiving cavity 11 more compact, and improving the structural strength of the cleaning mechanism 20. Moreover, the fourth groove 2324 is located on one side of the first groove 2323 along the third direction, and the two are adjacent, which is convenient to process and improves the compactness of the structure of the second support 232.

[0173] Specifically, in combination with Figure 26It can be known that the second locking body 291 of the second locking piece 29 in the embodiment includes a cover plate 911, a pressing block 912 and a third elastic element 913. The cover plate 911 is buckled on the second support 232 and surrounds the second support 232 to form a second installation space. Specifically, the cover plate 911 is buckled on the fourth groove 2324 and surrounds the fourth groove 2324 to form the second installation space. The second installation space is provided with a first connecting opening 9111 and a second connecting opening 9112. The first connecting opening 9111 is located on one side of the second installation space along the third direction, and the second connecting opening 9112 is located on the side of the second installation space close to the second clamping part. The pressing block 912 includes a pressing part 9121 and a main body part 9122. The main body part 9122 is located in the second installation space, and the pressing part 9121 is connected to the side of the main body part 9122 close to the first connecting opening 9111 and is located outside the second installation space, that is, the pressing part 9121 is located at the bottom of the second support 232 along the third direction. This not only can reduce the transverse length of the second support 232 along the first direction, but also is convenient for the operator to press the pressing part 9121 along the third direction to unlock the second clamping part 292.

[0174] Among them, the second clamping part 292 is connected to the side of the main body part 9122 close to the second connecting opening 9112 and is buckled with the second clamping part. The third elastic element 913 is connected between the side of the main body part 9122 away from the pressing part 9121 and the inner wall surface of the second installation space. When the second support 232 needs to be extracted, the main body part 9122 can be pushed to drive the second clamping part 292 to separate from the second clamping part by pressing the pressing part 9121 to overcome the elastic force of the third elastic element 913. When the second support 232 needs to be locked in the second sliding space 2311, the second clamping part 292 can be buckled with the second clamping part.

[0175] Specifically, please refer to Figure 12 , the first support 231 is provided with a third connecting opening 2313 at the position close to the second clamping part 292, the third connecting opening 2313 communicates with the second connecting opening 9112, and the second clamping part includes a second clamping groove 2312 (as Figure 26As shown in FIG. 9, the second locking member 29 further comprises a second locking groove 2312 and a third elastic element 913. The second locking groove 2312 is arranged on one side of the third connecting opening 2313 along the third direction. At this time, the second locking portion 292 comprises a locking protruding structure matched with the second locking groove 2312, and the width of the second locking portion 292 along the third direction is smaller than the width of the third connecting opening 2313 along the third direction, so that the second locking portion 292 can move along the third direction to leave the second locking groove 2312 to be unlocked under the pushing action of the pressing block 912. The third elastic element 913 comprises a spring, and the axis of the spring is parallel to the third direction and connected to the main body portion 9122 of the pressing block 912 and the side of the second mounting space away from the main body portion 9122 along the third direction. Thus, when it is needed to lock the second support 232 in the second sliding space 2311, the distance between the pressing portion 9121 of the pressing block 912 and the third connecting opening along the third direction is adjusted until the second locking portion 292 can enter the third connecting opening and be locked with the second locking groove 2312 under the elastic force of the third elastic element 913. When it is needed to take out the second support 232, the pressing portion 9121 is pushed along the compression direction of the third elastic element 913 to separate the second locking portion 292 from the second locking groove 2312, and then the second support 232 can be extracted along the first direction.

[0176] As shown in FIG. 9, the second locking member 29 further comprises a second locking groove 2312 and a third elastic element 913. The second locking groove 2312 is arranged on one side of the third connecting opening 2313 along the third direction. At this time, the second locking portion 292 comprises a locking protruding structure matched with the second locking groove 2312, and the width of the second locking portion 292 along the third direction is smaller than the width of the third connecting opening 2313 along the third direction, so that the second locking portion 292 can move along the third direction to leave the second locking groove 2312 to be unlocked under the pushing action of the pressing block 912. The third elastic element 913 comprises a spring, and the axis of the spring is parallel to the third direction and connected to the main body portion 9122 of the pressing block 912 and the side of the second mounting space away from the main body portion 9122 along the third direction. Thus, when it is needed to lock the second support 232 in the second sliding space 2311, the distance between the pressing portion 9121 of the pressing block 912 and the third connecting opening along the third direction is adjusted until the second locking portion 292 can enter the third connecting opening and be locked with the second locking groove 2312 under the elastic force of the third elastic element 913. When it is needed to take out the second support 232, the pressing portion 9121 is pushed along the compression direction of the third elastic element 913 to separate the second locking portion 292 from the second locking groove 2312, and then the second support 232 can be extracted along the first direction. Figure 9 As shown in FIG. 9, the second locking member 29 further comprises a second locking groove 2312 and a third elastic element 913. The second locking groove 2312 is arranged on one side of the third connecting opening 2313 along the third direction. At this time, the second locking portion 292 comprises a locking protruding structure matched with the second locking groove 2312, and the width of the second locking portion 292 along the third direction is smaller than the width of the third connecting opening 2313 along the third direction, so that the second locking portion 292 can move along the third direction to leave the second locking groove 2312 to be unlocked under the pushing action of the pressing block 912. The third elastic element 913 comprises a spring, and the axis of the spring is parallel to the third direction and connected to the main body portion 9122 of the pressing block 912 and the side of the second mounting space away from the main body portion 9122 along the third direction. Thus, when it is needed to lock the second support 232 in the second sliding space 2311, the distance between the pressing portion 9121 of the pressing block 912 and the third connecting opening along the third direction is adjusted until the second locking portion 292 can enter the third connecting opening and be locked with the second locking groove 2312 under the elastic force of the third elastic element 913. When it is needed to take out the second support 232, the pressing portion 9121 is pushed along the compression direction of the third elastic element 913 to separate the second locking portion 292 from the second locking groove 2312, and then the second support 232 can be extracted along the first direction.

[0177] Specifically, the first guide member comprises a guide hole 931 arranged through the main body portion 9122 along the second direction, and the second guide member comprises a fixed shaft 932. The length of the guide hole 931 extends along the third direction, the size of the fixed shaft 932 along the third direction is smaller than the size of the guide hole 931 along the third direction, the size of the fixed shaft 932 along the first direction is matched with the size of the guide hole 931 along the first direction, and the fixed shaft 932 is arranged in the guide hole 931 and connected with the cover plate 911. Thus, through the cooperation between the guide hole 931 and the fixed shaft 932, not only the stability of the main body portion 9122 moving along the third direction against the third elastic element 913 can be guided, but also the moving distance of the main body portion 9122 can be limited.

[0178] It can be seen that the cleaning device provided by the embodiment can extract the cleaning member 21 and the second support 232 respectively, and when the cleaning member 21 and the second support 232 are installed in the receiving cavity 11 of the body 10 to perform cleaning work under the driving of the cleaning device, the cleaning member 21 can be driven by the first driving assembly 22 to move to the first position in the first direction to extend out of the body 10 to abut against the corner of the wall for edge cleaning. Since the cleaning member 21 in the first position is flush with or exceeds the straight line 13 passing through the apex 12, the part of the cleaning member 21 extending out of the body 10 can clean all areas between the peripheral edge of the body 10 and the wall surface, and there is no case that even if the cleaning member 21 extends out of the body 10, there is a cleaning blind area between the body 10 and the wall surface, thereby improving the cleaning coverage of the cleaning device on the surface to be cleaned. When the cleaning device travels to a place without a corner area for cleaning, the cleaning member 21 can be driven by the first driving assembly 22 to retract into the receiving cavity 11 of the body 10. When the cleaning member 21 is a roller 212, the roller 212 retracted into the receiving cavity 11 cleans the surface to be cleaned along the travel path of the cleaning device, and when a corner area is encountered, the roller 212 is driven by the first driving assembly 22 to move to the first position extending out of the body 10 to perform edge cleaning. Since the end of the roller 212 close to the wall surface in the first position is flush with or exceeds the straight line 13 passing through the apex 12 of the body 10, the roller 212 can fully clean the area between the peripheral edge of the body 10 and the wall surface, thereby improving the cleaning coverage of the roller 212.

[0179] When the cleaning device in the embodiment further includes the sewage tank 40, the clean water tank 30 and the squeegee 50, the sewage tank 40 is arranged on the body 10 and located on the side of the cleaning member 21 away from the second support 232, and the sewage tank 40 is used to collect sewage on the cleaning member 21. The clean water tank 30 is arranged on the body 10 and located on the side of the cleaning member 21 away from the ground in the third direction, so that the clean water and / or cleaning liquid in the clean water tank 30 is delivered to the cleaning member 21 at a close distance through the pipeline to soak the cleaning member 21.

[0180] The wiper plate 50 is connected to the second support 232 and abuts against the surface of the cleaning member 21, and is used to scrape the dirty water on the cleaning member 21 and then deliver the dirty water to the dirty water tank 40 for temporary storage. In the process of scraping the dirty water, the garbage on the cleaning member 21 will be deposited on the side of the wiper plate 50 close to the cleaning member 21. Since the wiper plate 50 is difficult to be detached from the cleaning device, the garbage is also difficult to be cleaned from the wiper plate 50. In this embodiment, the wiper plate 50 is connected to the second support 232, so that when the second support 232 is extracted, the wiper plate 50 can also be extracted with the second support 232, thereby facilitating the full cleaning of the extracted wiper plate 50, and the cleaning effect of the wiper plate 50 is good.

[0181] Please refer to Figure 10 and Figure 27 The second support 232 of this embodiment is also provided with a water supply channel 2325 and a plurality of water spray openings 2326. The water supply channel 2325 is laid in the second support 232 along the first direction. The water spray openings 2326 are arranged on the side of the second support 232 close to the cleaning member 21 and are in communication with the water supply channel 2325, and at least one or more water spray openings 2326 are arranged opposite to at least part of the cleaning member 21 extending out of the body 10. When the water supply channel 2325 is supplied with water and / or cleaning liquid, the water and / or cleaning liquid can be sprayed through the water spray openings 2326 to the cleaning member 21 located in the first sliding space 2321 of the second support 232, so that the cleaning member 21 is fully wetted and self-cleaning to better clean the surface to be cleaned, and the cleaning effect and cleaning efficiency of the cleaning member 21 on the surface to be cleaned are improved. The water and / or cleaning liquid can be stored in the clean water tank 30, and the clean water tank 30 is in communication with the water supply channel 2325 through a connecting pipeline to inject clean water, cleaning liquid, etc. into the water supply channel 2325. At the same time, since at least one or more water spray openings 2326 are arranged opposite to at least part of the cleaning member 21 extending out of the body 10 even beyond the apex 12, when the cleaning member 21 sweeps along the edge, the part of the cleaning member 21 extending out of the apex 12 can also be wetted and self-cleaned to achieve better cleaning effect and cleaning efficiency. The second support 232 is provided with a sealing cover 2327 covering the water supply channel 2325, and the sealing cover 2327 is provided with a water inlet nozzle 2328 in communication with the water supply channel 2325. The water inlet nozzle 2328 can be connected to the clean water tank 30 through a connecting pipeline, so that the clean water and cleaning liquid in the clean water tank 30 can enter the water supply channel 2325 through the water inlet nozzle 2328.

[0182] Since the existing wiper 50 will cause the garbage on the cleaning member 21 to be discharged into the sump tank 40 through the drain port 53 when the wiper 50 scrapes the sewage on the cleaning member 21 and discharges the sewage into the sump tank 40, the garbage may block the sewage inlet of the sump tank 40, thereby reducing the sewage collection efficiency of the sump tank 40 or causing the sewage to overflow the sump tank 40 and pollute the surface to be cleaned again. For this purpose, please refer to Figure 28 and Figure 29 In the present embodiment, the wiper 50 of the cleaning device comprises a plate body 51 connected to the connecting bracket 23. Specifically, the plate body 51 is connected to the second bracket 232. The plate body 51 has oppositely arranged first and second side surfaces 511 and 512. The plate body 51 is provided with a wiper portion 52, a drain port 53, and a filtering structure. The wiper portion 52 is protruded from the first side surface 511 and located at the side edge of the drain port 53 in the second direction, and abuts against the cleaning member 21, so that the wiper portion 52 can scrape the sewage on the cleaning member 21. The drain port 53 is provided through the thickness direction of the plate body 51 to at least guide the sewage on the first side surface 511 to the second side surface 512, so that the sewage is guided from the second side surface 512 to the sump tank 40. The filtering structure is covered in the drain port 53 to filter the garbage during the process of guiding the sewage from the drain port 53 to the second side surface 512. The garbage filtered by the filtering structure will not enter the sump tank 40, thereby improving the sewage collection efficiency of the sump tank 40 and avoiding the secondary pollution caused by the sewage flowing to the ground due to the failure of being collected by the sump tank 40 in time.

[0183] The filtering structure in the present embodiment can specifically comprise a filter screen provided in the drain port 53, or can comprise a plurality of micro filter holes 54 with sizes smaller than those of the drain port 53. When the filtering structure comprises a plurality of filter holes 54, the plurality of filter holes 54 can be distributed and provided through the plate body 51. At this time, the filter holes 54 not only play a role in filtering the garbage, but also guide the sewage from the first side surface 511 to the second side surface 512 as the drain port 53, and then discharge the sewage into the sump tank 40. The second side surface 512 is provided with a water outlet 55 on the side away from the first bracket 231 in the second direction, and the sewage guided by the filter holes 54 to the second side surface 512 flows into the sump tank 40 through the water outlet 55. Moreover, the axis of the filter hole 54 can be inclined towards the direction close to the water outlet 55, so that the sewage can be better guided to the water outlet 55, and then discharged into the sump tank 40 through the water outlet 55.

[0184] The water outlet 55 in the embodiment can be arranged at the middle position region of the plate body 51. However, in some embodiments of the present application, since the wiper plate 50 needs to extend out of the body 10 along with the cleaning member 21 to clean the cleaning blind area (such as the blind area between the body 10 and the wall, obstacles, etc.), in order to ensure that the sewage can still be discharged into the sump 42 of the sewage tank 40 after the wiper plate 50 extends out of the body 10 along with the cleaning member 21, the plate body 51 can extend out of the side of the body 10, and the water outlet 55 in the embodiment can be arranged on the side of the plate body 51 away from the side where the plate body 51 extends out. Specifically, the distance from the water outlet 55 to one end of the plate body 51 in the first direction can be less than the distance from the water outlet 55 to the other end of the plate body 51 in the first direction, so that even if the end of the plate body 51 away from the water outlet 55 extends out of the body 10, the water outlet 55 can still correspond to the sump 42, so that the sewage scraped off the cleaning member 21 by the wiper plate 50 can be discharged into the sump 42, and the sewage discharged from the water outlet 55 of the wiper plate 50 can be prevented from falling to the ground when the cleaning member 21 extends out of the body 10.

[0185] The length of the plate body 51 in the embodiment extends in the length direction of the cleaning member 21 (i.e., the roller 212). The length direction of the plate body 51 is the first direction in the embodiment. In order to improve the filtering efficiency of the sewage scraped off by the wiper part 52, the plurality of filtering holes 54 in the embodiment are arranged in at least one row (such as one row, two rows, three rows, four rows, etc.) in the length direction of the plate body 51, so that the plurality of filtering holes 54 in the at least one row can simultaneously filter the sewage, thereby improving the filtering efficiency of the sewage. The filtered garbage can be left in the space between the wiper part 52 and the overflow hole, or directly fall to the ground. When the garbage falls to the ground, it can be swept and collected into the dust box 70 by the middle sweeping assembly 80 of the cleaning device. Since most of the garbage has been swept and collected by the side brush assembly 60 and the middle sweeping assembly 80 before the cleaning member 21 cleans the surface to be cleaned, the garbage on the cleaning member 21 is generally not too much and has a small volume, so that the garbage scraped off by the wiper part 52 from the cleaning member 21 can be temporarily left in the space between the wiper part 52 and the filtering hole 54. Since the second bracket 232 is detachable and removable, the wiper plate 50 connected to the second bracket 232 can also be removed together with the second bracket 232, so that the garbage left on the first side surface 511 of the removed wiper plate 50 can be cleaned.

[0186] The filter holes 54 in the embodiment can include at least one of a circular hole, a square hole, and a diamond hole. The maximum width of the filter holes 54 is not less than 1 mm and not greater than 2 mm, that is, the maximum width of the filter holes 54 can include one of 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, etc. Thus, the garbage is filtered through the filtering of the above size range. The filter holes 54 in the embodiment are preferably circular holes, which are convenient to process. When the filter holes 54 include circular holes, the maximum width is the diameter of the filter holes 54, that is, the diameter of the filter holes 54 is not less than 1 mm and not greater than 2 mm. The minimum spacing between the two adjacent filter holes 54 is not less than 1 mm, and the maximum spacing between the two adjacent filter holes 54 is not greater than 2 mm, that is, the spacing between the two adjacent filter holes 54 is between 1 mm and 2 mm, and the spacing between the two adjacent filter holes 54 can specifically include one of 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, etc. If the spacing between the two adjacent filter holes 54 is too small (e.g., less than 1 mm), the structural strength of the wiper 52 will be reduced, and if the spacing is too large, the filtering efficiency of the garbage will be poor. Therefore, the spacing between the two adjacent filter holes 54 in the embodiment is set within the above range, which can ensure the structural strength of the wiper 50 and improve the filtering efficiency of the garbage.

[0187] As Figure 30 and Figure 6As shown, the wastewater tank 40 provided in this embodiment is disposed on the body 10 and located on the side of the cleaning component 21 away from the connecting bracket 23. The wastewater tank 40 includes a tank body 41 and a water collection tank 42. A liquid storage chamber 411 is provided inside the tank body 41, and a suction channel 412 communicating with the liquid storage chamber 411 is provided on the top of the tank body 41. The liquid storage chamber 411 includes a top surface 4111, which is located on the top inner wall of the liquid storage chamber 411 along a third direction near the clean water tank 30. The water collection tank 42 is disposed outside the tank body 41 and below the scraper 50. The water collection tank 42 is used to collect wastewater scraped off the cleaning component 21 by the scraper 50. A connecting channel 43 is provided between the water collection tank 42 and the liquid storage chamber 411, and the port of the connecting channel 43 communicating with the water collection tank 42 is at a predetermined distance from the top surface 4111. In this embodiment, the suction channel 412 of the sewage tank 40 can be connected to a negative pressure device. The negative pressure device applies negative pressure to the storage chamber 411 so that the air pressure in the storage chamber 411 is lower than the air pressure in the collection tank 42. After a certain amount of sewage is collected in the collection tank 42, when the air pressure in the storage chamber 411 is lower than that in the collection tank 42, the sewage will enter the storage chamber 411 along the connecting channel 43 for storage. Since the storage chamber 411 is a relatively sealed structure, and there is a predetermined distance between the port connecting the connecting channel 43 and the collection tank 42 and the top surface 4111, the sewage tank 40 is less likely to leak water when the cleaning device body 10 is flipped or subjected to strong shaking, thereby avoiding sewage outflow that could cause secondary pollution or even damage to the electrical components inside the cleaning device.

[0188] like Figure 31 As shown, the negative pressure device in this embodiment may specifically include a first vacuum pump 44 and an air connection pipe 45. The first vacuum pump 44 is installed inside the body 10 and located on one side of the dust box 70. The air connection pipe 45 connects the air intake of the first vacuum pump 44 and the suction channel 412. Activating the first vacuum pump 44 will perform a vacuum operation on the storage chamber 411 of the wastewater tank 40, thereby timely collecting the wastewater in the collection tank 42 into the storage chamber 411, preventing wastewater spillage and avoiding secondary pollution. Specifically, since the wastewater tank 40 is installed on one side of the cleaning component 21 via the mounting shell 15 of the body 10, the mounting shell 15 is provided with a second connection hole 151 adapted to the air connection pipe 45 near the suction channel 412 of the wastewater tank 40. The second connecting hole 151 is connected to the suction channel 412, and a sealing ring 152 is provided at the connection between the second connecting hole 151 and the suction channel 412 to improve the airtightness between the air circuit connecting pipe 45 and the suction channel 412 during the negative pressure extraction process.

[0189] Further, the mounting bracket 24 in the embodiment is rotationally connected with the body 10 and can rotate away from the surface to be cleaned, and a torsion spring is in abutment between the mounting bracket 24 and the body 10, which can apply a force to the mounting bracket 24 towards the surface to be cleaned, so that the mounting bracket 24 can better abut against the surface to be cleaned under the pushing force of the torsion spring when the cleaning member 21 is normally working, thereby improving the cleaning strength of the cleaning member 21 when cleaning the surface to be cleaned. The cleaning device further comprises a lifting rope 243 and a mounting block 242, one end of the lifting rope 243 is connected with a fixing block, and the other end of the lifting rope 243 is connected with a second driving assembly arranged in the body 10. The mounting block 242 is arranged on the mounting bracket 24 and has a gap with the mounting bracket 24. Please refer to Figure 32 and Figure 33 The side of the mounting block 242 close to the mounting bracket 24 is provided with an abutment groove 2421, and the mounting block 242 is further provided with a strip-shaped opening groove 2422 for the lifting rope 243 to pass through. The strip-shaped opening groove 2422 is in communication with the abutment groove 2421, the fixing block is matched with the inner wall surface of the abutment groove 2421 and is in abutment in the abutment groove 2421 under the pulling force of the lifting rope 243. Thus, the lifting rope 243 and the mounting block 242 are not locked by using a locking member, and the operation is convenient and the connection is reliable. The second driving assembly is installed in the body 10 and can comprise a motor (which is different from the motor as the first driving member 221) and a roller, the other end of the lifting rope 243 is wound on the roller, and the motor drives the roller to rotate to wind the lifting rope 243. During the winding of the lifting rope 243, since the fixing block is in abutment in the abutment groove 2421, the mounting bracket 24 can be pulled to rotate away from the surface to be cleaned, so that the cleaning member 21 is separated from the surface to be cleaned, thereby avoiding the cleaning member 21 from contacting the carpet to pollute the carpet when the surface to be cleaned is a ground surface (such as a carpet) which is not suitable for cleaning by the cleaning member 21.

[0190] The second embodiment of the present application provides a control method of a cleaning device, which is described by taking the cleaning device as an example. The structure of the cleaning device is specifically described in the first embodiment of the present application, which will not be repeated here. Please refer to ​ The control method provided by the embodiment comprises the following steps:

[0191] Step S11: controlling the motor of the first driving assembly 22 to rotate according to the received first signal, so as to drive the cleaning member 21 of the cleaning device to move to one of the first position and the second position.

[0192] Step S12: in response to the second signal when the cleaning member 21 reaches one of the first position and the second position, controlling the motor to stop rotating, and when the motor is started again, controlling the motor to rotate in the direction opposite to the last rotation direction, so as to drive the cleaning member 21 to move to the other of the first position and the second position.

[0193] Therefore, the embodiment can drive the cleaning member 21 to switch between the first position and the second position by controlling the motor of the first driving assembly 22 to rotate, thereby improving the cleaning coverage of the cleaning member 21 on the surface to be cleaned.

[0194] The second signal in the embodiment includes a current value of a current generated by the motor. In step S12, the step of controlling the motor to stop rotating can specifically include: determining whether the current value is greater than a predetermined value, and if so, controlling the motor to stop rotating. When the first limiting member 251 and the second limiting member 252 of the cleaning device abut, the motor can generate a larger current due to the occurrence of a locked-rotor phenomenon. At this time, in order to avoid the energy consumption caused by the locked-rotor phenomenon of the motor to the cleaning device, and to avoid the long-term locked-rotor phenomenon to reduce the performance of the motor or even damage the motor, the embodiment can detect the current value of the current generated by the motor, and when the current value of the motor is greater than a predetermined value, control the motor to stop rotating. When the motor is started again, the motor is controlled to rotate in the opposite direction to the last rotation direction (for example, the motor is controlled to reverse when the last rotation direction of the motor is forward), so as to drive the cleaning member 21 to move reversely to the first position or the second position. The control mode is reliable and timely.

[0195] The second signal in the embodiment can also include a trigger signal of the first limiting switch 253 or the second limiting switch 254 triggered by the second transmission member 223 of the first driving assembly 22. In step S12, the step of controlling the motor to stop rotating can also include: controlling the motor to stop rotating in response to the received trigger signal. That is, the embodiment can control the motor to stop rotating by the received trigger signal of the first limiting switch 253 or the second limiting switch 254 being triggered, so that the cleaning member 21 can be stably and reliably stopped at the first position or the second position. Moreover, the embodiment can control the motor to stop rotating by combining the received trigger signal with the detection of the current change of the motor, which is not only more accurate and reliable, but also can ensure that the cleaning member 21 can always be stopped at the specified first position or second position.

[0196] The third embodiment of the present application also provides a base station, which includes a cleaning device. The structure of the cleaning device is specifically described in the first embodiment of the present application, and will not be described here again.

[0197] For purposes of the description hereinafter, the terms "upper", "lower", "right", "left", "rear", "front", "vertical" and "horizontal" as can be perceived herein relative to the accompanying drawings refer to the orientation of the components being described. However, it is to be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device described herein relative to the other device or structure is inverted, then a spatially relative term such as "above" can be interpreted as meaning "below" or "below" can be interpreted as meaning "above". The device can also be oriented in other ways (rotated at 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
