Description

Technical Field

[0002] Cleaning equipment such as sweeping robots, mopping machines or floor scrubbers are a type of smart home appliance that can automatically clean the floor in a room with a certain degree of artificial intelligence. However, when the cleaning mechanism at the bottom of the cleaning equipment cleans blind corners such as corners, wall edges, and obstacle edges, it is limited by the length of the drum of the cleaning mechanism and is affected by the outer contour of the cleaning equipment. As a result, when the cleaning equipment moves along the wall, the blind area between the wall and the edge of the drum cannot be cleaned, resulting in an area in the corner area that cannot be cleaned properly, making the cleaning coverage rate of the cleaning equipment low.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0100] In order to solve the problem that the roller 212 of the current cleaning equipment cannot clean along the edge and has a low cleaning coverage rate, the first embodiment of the utility model provides a cleaning device.

[0101] First, the directions mentioned below in the embodiments of the present invention are described as follows:

[0102] First direction: The first direction is Figure 1 The direction indicated by the arrow X is the moving direction of the cleaning member 21 of the cleaning device.

[0103] Second direction: The second direction is Figure 1 The direction indicated by the arrow Y.

[0104] The third direction: The third direction is Figure 2 The direction indicated by the arrow Z is the height direction of the cleaning device.

[0105] See also Figures 1 to 8 , the cleaning device in this embodiment includes a body 10 and a cleaning mechanism 20. The body 10 is provided with a storage chamber 11. Along the first direction, at least one side of the storage chamber 11 passes through the outer peripheral edge of the body 10, and the outer peripheral edge of the body 10 has a vertex 12 along the first direction, and the vertex 12 is the end point of the outer peripheral edge of the body 10 closest to the blind area. The outer peripheral edge contour of the body 10 may include square, circular, elliptical, diamond, polygonal and other special-shaped structures according to actual design requirements. Regardless of the shape of the body 10, the vertex 12 is the end point of the outer peripheral edge of the body 10 along the extension direction of the cleaning member 21 (i.e., the first direction) closest to the wall equilateral corner area of ​​the corner. If the outer peripheral edge contour of the body 10 is circular, the vertex 12 is the end point of the outer peripheral edge of the circular body 10 along the first direction. The vertex 12 of the outer peripheral edge of the body 10 has a straight line 13 passing through the vertex 12 and perpendicular to the first direction. For example, when the outer peripheral edge contour of the body 10 is a circular contour, the straight line 13 includes a tangent line of the circular contour at the vertex 12; when the outer peripheral edge contour of the body 10 is a rectangular contour, the straight line 13 coincides with one side of the rectangular contour along the first direction.

[0106] like Figure 7 and Figure 8 As shown, the cleaning mechanism 20 includes a cleaning member 21, a first driving assembly 22 and a connecting bracket 23. The connecting bracket 23 is installed in the storage chamber 11 and can move relative to the body 10 along a first direction. The first driving assembly 22 is installed in the storage chamber 11 and connected to the connecting bracket 23, and the cleaning member 21 is connected to the connecting bracket 23. The cleaning member 21 has a first position in which it moves along the first direction with the connecting bracket 23 to exceed or be flush with the straight line 13, and a second position in which it moves along the connecting bracket 23 to retract into the storage chamber 11. The first driving assembly 22 drives the connecting bracket 23 to drive the cleaning member 21 to move between the first position and the second position.

[0107] When the cleaning device is traveling and moves to a blind spot such as a corner, a wall, or an obstacle edge, the first driving assembly 22 can drive the cleaning member 21 to move to the first position along the first direction so as to extend the cleaning member 21 from the body 10 to the blind spot 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 vertex 12, the portion of the cleaning member 21 extending from the body 10 can clean all areas between the outer edge of the body 10 and the wall surface, and there will be no blind spot between the body 10 and the wall surface even if the cleaning member 21 is extended outside the body 10, thereby improving the cleaning coverage of the cleaning device on the surface to be cleaned. When the cleaning device travels to a place where there is no blind spot for cleaning, the first driving assembly 22 can drive the cleaning member 21 to retract into the storage chamber 11 of the body 10. If the cleaning member 21 is a roller 212, the roller 212 retracted into the storage chamber 11 cleans the surface to be cleaned along the driving path of the cleaning device. When encountering a corner area, the first driving assembly 22 drives the roller 212 to move to the first position extending out of the body 10 to clean the edge. Since the end of the roller 212 at the first position close to the wall is flush with or beyond the straight line 13 passing through the vertex 12 of the body 10, the roller 212 can fully clean the area between the outer peripheral edge of the body 10 and the wall, thereby improving the cleaning coverage of the roller 212.

[0108] It can be seen that the cleaning device provided in this embodiment includes a body 10 and a cleaning mechanism 20. The body 10 is provided with a storage cavity 11. The outer peripheral edge of the body 10 has a vertex 12 along the first direction, and the vertex 12 has a straight line 13 passing through the vertex 12 and perpendicular to the first direction. The cleaning member 21 of the cleaning mechanism 20 has a first position that moves along the first direction with the connecting bracket 23 to exceed or be flush with the straight line 13. When the cleaning member 21 needs to clean the blind area, the first driving component 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 is extended out of the body 10, when cleaning, the area between the cleaning member 21 and the outer peripheral edge of the body 10 will be cleaned, and there will be no cleaning blind area. When the cleaning member 21 cleans the blind area close to the edge, the cleaning coverage rate of the cleaning member 21 on the surface to be cleaned is further improved, and the blind corners of the blind area are reduced, so as to achieve an ideal cleaning effect and provide a good user experience. When it is not necessary to clean the edge, the first driving component 22 drives the connecting bracket 23 to drive the cleaning member 21 to retract to the second position in the storage chamber 11. In other words, the first driving component 22 can drive the cleaning member 21 to switch flexibly 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 surface to be cleaned by the cleaning member 21.

[0109] Along the second direction, the main body 10 of the cleaning device includes a first end 101 and a second end 102, and the distance between the cleaning member 21 and the first end 101 along the second direction is smaller than the distance between the cleaning member 21 and the second end 102 along the second direction, that is, the cleaning member 21 is located in the rear area of ​​the main body 10, so as to reserve sufficient installation space for the main body 10 except the area where the cleaning member 21 is located, so as to install corresponding devices.

[0110] like Figures 1 to 6 As shown, the body 10 of the cleaning device in this embodiment may include a mounting shell 15, a travel assembly 16, a clean water tank 30, a sewage tank 40, a side brush assembly 60, a dust box 70 and a middle sweep assembly 80. The mounting shell 15 is the main frame of the cleaning device. The clean water tank 30 and the sewage tank 40 are both connected to the body 10 through the mounting shell 15, and the clean water tank 30 is located above the sewage tank 40 along the third direction. The travel assembly 16 is arranged at the bottom of the mounting shell 15, and the travel assembly 16 is used to drive the cleaning device to travel to the area to be cleaned for cleaning. 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. A clean water injection port is arranged on the clean water tank 30. When the cleaning device enters the base station, the clean water injection port is connected to the clean water bucket of the base station so that the base station injects clean water into the clean water tank 30. The storage chamber 11 is arranged at the bottom of the installation shell 15, and the connection bracket 23 can also be connected to a wiper 50 for wiping the cleaning member 21, and the sewage tank 40 is located below the wiper 50 to collect the sewage scraped from the cleaning member 21 by the wiper 50. A sewage extraction port 46 is arranged on one side of the sewage tank 40, and the sewage extraction port 46 is used to communicate with the sewage bucket of the base station when the cleaning device enters the base station, so as to discharge the sewage in the sewage tank 40 into the sewage bucket of the base station. As one of the core components of the cleaning device, the side brush assembly 60 can be installed at the edge of the bottom of the installation shell 15 to clean blind areas that are usually ignored, such as corners and walls.

[0111] The middle sweep assembly 80 in this embodiment is disposed at the bottom of the body 10, and the cleaning member 21 is located at one side of the middle sweep assembly 80 along the second direction. The middle sweep assembly 80 is the main cleaning component of the cleaning device, and is used to sweep the garbage on the driving path of the cleaning device into the dust box 70. The middle sweep assembly 80 is usually located at the middle position of the bottom of the body 10, and the cleaning member 2 is located at one side of the middle sweep assembly 80 near the rear of the body 10, so that the cleaning member 2 can wet clean the area cleaned by the middle sweep assembly 80 again.

[0112] Specifically, the middle sweep assembly 80 of the cleaning device is arranged in the middle area of ​​the bottom surface of the mounting shell 15, and the dust box 70 is arranged at a position of the mounting shell 15 close to the middle sweep assembly 80. A second vacuum pump 73 for pumping negative pressure to the dust box 70 is arranged in the body 10, so that the dust box 70 can suck in and temporarily store the garbage cleaned by the middle sweep assembly 80 and the side brush assembly 60 by pumping negative pressure to the dust box 70 by the second vacuum pump 73. Moreover, the bottom of the body 10 of this embodiment is also provided with an air suction dust collection port 71 and an air blowing dust collection port 72 connected to the dust box 70. The base station is provided with a dust collection fan. After the cleaning device moves to the base station, the air suction dust collection port 71 and the air blowing dust collection port 72 are connected to the dust collection fan, so that the garbage in the dust box 70 is recycled into the dust collection box of the base station. In addition, a recharge indicator 17 is also provided on the body 10, and the recharge indicator 17 is used to indicate the docking of the cleaning device and the base station, so as to return to the base station for charging, backwashing, dust collection and other operations.

[0113] like Figure 7 and Figure 8 As shown, the cleaning mechanism 20 provided in this embodiment also includes a mounting bracket 24. The mounting bracket 24 is installed in the storage chamber 11, and the mounting bracket 24 is provided with a avoidance opening 241 along the second direction. The connecting bracket 23 is installed on the mounting bracket 24 and can move relative to the mounting bracket 24 along the first direction. The connecting bracket 23 is at least partially covered and arranged on the avoidance opening 241, and the first driving component 22 is installed on the mounting bracket 24 and connected to the connecting bracket 23 through the avoidance opening 241. Specifically, the connecting bracket 23 includes a first bracket 231 and a second bracket 232, the first bracket 231 is connected to the mounting bracket 24 and can move relative to the mounting bracket 24 along the first direction, and the first bracket 231 is at least partially covered and arranged on the avoidance opening 241. The first driving component 22 is installed on the mounting bracket 24 and is connected to the portion of the first bracket 231 exposed to the avoidance opening 241. The second bracket 232 is connected to the first bracket 231 and the cleaning member 21 and is located between the first bracket 231 and the cleaning member 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 member 21 on the second bracket 232 to move along the first direction to the first position or the second position.

[0114] Thus, in this embodiment, after the connecting bracket 23 is movably connected with the mounting bracket 24 so that the connecting bracket 23 can move relative to the mounting bracket 24 along the first direction, the first driving assembly 22 can be installed on the mounting bracket 24 and connected to the connecting bracket 23 along the avoidance opening 241, so as to drive the connecting bracket 23 to move relative to the mounting bracket 24 along the first direction. After the cleaning member 21 is connected with the connecting bracket 23, the mounting bracket 24 is installed in the storage chamber 11, so that the cleaning member 21 is installed in the storage chamber 11 of the body 10, and the installation difficulty is low and the assembly is efficient. Moreover, the first driving assembly 22 is connected with the connecting bracket 23 through the avoidance opening 241 set on the mounting bracket 24, which not only reduces the assembly difficulty between the connecting bracket 23 and the first driving assembly 22, but also makes the overall structure of the cleaning mechanism 20 more compact and reliable, saving installation space. At the same time, a storage groove for accommodating the first drive component 22 can be correspondingly arranged in the storage cavity 11 of the main body 10. When the mounting bracket 24 is installed in the storage cavity 11, the first drive component 22 can be abutted against the storage groove by the mounting bracket 24, thereby further improving the compactness and structural reliability between the cleaning mechanism 20 and the main body 10.

[0115] See also Figure 8 In this embodiment, the first driving assembly 22 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 to the first driving member 221. The second transmission member 223 is located in the avoidance opening 241 and is connected to the connecting bracket 23, and the second transmission member 223 is transmission-connected to 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 along the first direction.

[0116] During the movement of the second transmission member 223 along the first direction, the cleaning member 21 connected to the connecting bracket 23 can be driven to switch back and forth between the first position and the second position. When the cleaning device travels to blind spots such as corners and furniture corners, the first driving member 221 drives the second transmission member 223 to drive the cleaning member 21 to move to the first position extending out of the vertex 12 of the outer peripheral edge of the body 10, so that the cleaning member 21 can clean along the edge and improve the cleaning coverage of the cleaning device. When the cleaning device travels to a wider area to be cleaned, 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 surface to be cleaned on the travel path of the cleaning device. Therefore, the cleaning device in this embodiment can flexibly switch between the first position and the second position by driving the cleaning member 21 through the first driving member 221 according to the environment of the surface to be cleaned, so as to improve the cleaning coverage of the cleaning device on the surface to be cleaned.

[0117] In this embodiment, the first driving member 221 includes a motor, the first transmission member 222 includes a gear, and the second transmission member 223 includes a rack. The gear is connected to the motor and can rotate along its own circumferential direction under the drive of the motor, and the rack is meshed with the gear. The length of the rack extends along the first direction. When the gear is driven to rotate by the motor, the rack can move relative to the gear along the first direction, and the rack can also drive the cleaning member 21 on the connecting bracket 23 connected thereto to move along the first direction to the first position or the second position. And, if Figure 8 As shown, the length of the rack is smaller than the length of the avoidance opening 241 along the first direction, so as to ensure that the rack can move along the first direction to drive the cleaning member 21 to switch between the first position and the second position, while the avoidance opening 241 will not hinder the movement of the cleaning member 21 between the first position and the second position.

[0118] like Figure 8 As shown, in order to prevent the cleaning member 21 from being separated from the body 10 or even falling to the ground from the body 10 under the action of the moving inertia during the movement of the cleaning member 21 to the first position, the cleaning mechanism 20 in this embodiment also includes a limiting assembly 25, which is arranged between the connecting bracket 23 and the mounting bracket 24. The limiting assembly 25 is used to limit the cleaning member 21 to 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 to the second position when the cleaning member 21 moves to the second position, so as to stably maintain the cleaning member 21 on the body 10. It can be seen that in this embodiment, the limiting assembly 25 can be used to prevent the cleaning member 21 from falling from the body 10 due to the moving inertia when the cleaning member 21 arrives at the first position, or, when the cleaning member 21 arrives at the second position, the cleaning member 21 can be prevented from continuing to move under the action of the moving inertia to cause a certain impact on the body 10, so as to stably and reliably maintain the cleaning member 21 in the storage cavity 11 of the body 10.

[0119] The limiting assembly 25 in this embodiment includes a first limiting member 251 and a second limiting member 252. The first limiting member 251 includes at least one, and 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 along the first direction, at least two second limiting members 252 are spaced apart and arranged on the other of the connecting bracket 23 and the mounting bracket 24. Among them, along the second direction, the projection of the first limiting member 251 is located between the projections of two adjacent second limiting members 252. Along 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 along the first direction, so that the first limiting member 251 can abut against the second limiting member 252 when moving along the first direction, thereby preventing the cleaning member 21 from continuing to move. When the first limiting member 251 moves along the first direction until it abuts against one of the second limiting members 252 , the cleaning member 21 will not continue to move, thereby limiting the cleaning member 21 to the first position or the second position.

[0120] Specifically, in this embodiment, the first stopper 251 can be arranged on a side of the connecting bracket 23 close to the mounting bracket 24 and can move along the first direction with the connecting bracket 23. When the connecting bracket 23 includes a first bracket 231 connected to the mounting bracket 24, the first stopper 251 can be specifically arranged on a side of the first bracket 231 close to the mounting bracket 24. At least two second stoppers 252 are arranged on a side of the mounting bracket 24 close to the connecting bracket 23. Since the first stopper 251 is located between two adjacent second stoppers 252 spaced apart along the first direction, when the first stopper 251 moves along the first direction to a position abutting against any second stopper 252, the cleaning member 21 can stop moving along the first direction, thereby improving the assembly reliability between the cleaning member 21 and the body 10 during the movement. Moreover, when the first stopper 251 abuts against the second stopper 252, the motor as the first driving member 221 will generate a large current due to the stall phenomenon. At this time, in order to avoid the energy consumption caused by the long-term stalling of the motor to the cleaning device, and to avoid the performance reduction or even damage of the motor due to the long-term stalling of the motor, the present embodiment can detect the motor current through the controller of the cleaning device, and when the motor current is greater than a predetermined value, the controller controls the motor to stop running. When the motor is restarted, the controller controls the motor to rotate in the opposite direction to the last rotation direction (if the motor rotated forward last time, the motor is reversed when it is restarted), so as to drive the cleaning member 21 to move in the opposite direction to the first position or the second position.

[0121] For example, the motor in this embodiment rotates forward before it stops for the first time. When the motor stops, the cleaning member 21 is in the first position. When the motor is started again, the motor is controlled to reverse, and the cleaning member 21 will move in the opposite direction to the second position under the drive of the motor. When the cleaning member 21 moves to the second position, the first limit member 251 abuts against another second limit member 252 close to the second position, thereby preventing the cleaning member 21 from continuing to move and hitting the body 10 or falling from the body 10. Similarly, when the cleaning member 21 is limited to the second position by the first limit member 251 and the second limit member 252 abutting against each other, the motor current becomes larger due to the occurrence of stalled rotor, and the controller controls the motor to stop rotating, so as to avoid the motor being stalled for a long time, which increases the energy consumption of the cleaning device and improves the service life of the motor.

[0122] In order to improve the stability of the cleaning member 21 during movement, the cleaning mechanism 20 in this embodiment also 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 move smoothly relative to the mounting bracket 24 along the first direction.

[0123] In this embodiment, at least two second stoppers 252 are disposed on at least one side of the mounting bracket 24 along the third direction, and at least one first stopper 251 is disposed on the connecting bracket 23 and is located between two adjacent second stoppers 252. The guide assembly 26 includes a guide shaft 261, the length of which extends along the first direction, the guide shaft 261 is disposed on at least one side of the mounting bracket 24 along the third direction and is fixedly connected to the second stopper 252, and the first stopper 251 is slidably connected to the guide shaft 261.

[0124] Thus, in this embodiment, by connecting the guide shaft 261 with the first stopper 251 and the second stopper 252, the connecting bracket 23 is movably mounted on the mounting bracket 24, and the connecting bracket 23 can be guided to move smoothly along the first direction by the guide shaft 261. At the same time, in the process of the connecting bracket 23 moving to drive the first stopper 251 to move along the length direction of the guide shaft 261, when the first stopper 251 abuts against the second stopper 252, the cleaning member 21 can be limited. It can be seen that in this embodiment, while connecting the connecting bracket 23 and the mounting bracket 24 by the guide shaft 261 to achieve guidance, the moving distance of the cleaning member 21 is also limited, so as to prevent the cleaning member 21 from falling or causing impact on the body 10 due to excessive movement.

[0125] The guide shafts 261 in this embodiment may include at least two, and the at least two guide shafts 261 are respectively arranged on the opposite sides of the mounting bracket 24 along the third direction, so as to improve the firmness and stability of the connection structure between the mounting bracket 24 and the connecting bracket 23, thereby guiding the connecting bracket 23 to move more smoothly along the first direction relative to the mounting bracket 24 through at least two guide shafts 261.

[0126] It can be seen that in this embodiment, the guide shaft 261 is connected with the first stopper 251 provided on the connecting bracket 23 and the second stopper 252 provided on the mounting bracket 24, which not only improves the assembly efficiency between the connecting bracket 23 and the mounting bracket 24, but also ensures that the connecting bracket 23 can be smoothly moved relative to the mounting bracket 24 along the first direction. At the same time, the first stopper 251 that can move with the connecting bracket 23 is used to make the first stopper 251 abut against the second stopper 252 on the mounting bracket 24, so as to accurately limit the moving distance of the cleaning member 21, thereby ensuring that the cleaning member 21 can be accurately switched between the first position and the second position.

[0127] like Figure 8 As shown, in order to further improve the accuracy and timeliness of controlling the operation of the motor, the limit assembly 25 in this embodiment also 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 is located on one side of the avoidance opening 241 along the first direction. When the first limit member 251 contacts one of the two adjacent second limit members 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 limit member 251 contacts the second limit member 252 of the two adjacent second limit members 252 close to the first limit switch 253, the second transmission member 223 contacts the first limit switch 253 to trigger the first limit switch 253, and the motor stops running when the first limit switch 253 is triggered, so that the cleaning member 21 is stably docked at the first position for edge cleaning.

[0128] In this embodiment, the second limit switch 254 is arranged on the mounting bracket 24 and is located at the other side of the avoidance opening 241 along the first direction. When the first limit member 251 contacts the other 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. Specifically, when 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 of the two adjacent second limit members 252 close to the second limit switch 254, the second transmission member 223 contacts the second limit switch 254 to trigger the second limit switch 254. When the second limit switch 254 is triggered, the motor stops running so that the cleaning member 21 can be stably docked at the second position for edge cleaning.

[0129] 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 in the first position and the second position, in this embodiment, if the distance that the first limit member 251 moves along the first direction between two adjacent second limit members 252 is the first distance, the distance that the second transmission member 223 (specifically, a rack in this embodiment) moves along the first direction between the first limit switch 253 and the second limit switch 254 is the second distance, so that the first distance is equal to the second distance, that is, when the first limit member 251 abuts against 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 running.

[0130] The first limit switch 253 and the second limit switch 254 in this embodiment may include a micro switch, a position sensor, etc. The first limit switch 253 and the second limit switch 254 are preferably micro switches. The micro switch is a contact mechanism with a small contact spacing and a quick-action mechanism, which performs a switching action with a specified stroke and a specified force. It is a switch with a driving rod on the outside. Because the contact spacing 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 contacting the micro switch with a very small force, with high sensitivity and timely control. Specifically, the motor and the micro switch can be connected to the controller of the cleaning device, and the controller can control the motor to stop running in response to the information that the micro switch is triggered.

[0131] Of course, in some embodiments of the utility model, the motor can be stopped by triggering the first limit switch 253 and the second limit switch 254 only by the second transmission member 223 (such as a rack), but in this way, if the first limit switch 253 and / or the second limit switch 254 (such as a micro switch) fails, it may not only cause the motor to fail to stop in time, but also the cleaning member 21 may not be able to stay at the specified position, and the control risk is relatively high. In this embodiment, the first limit member 251 and the second limit member 252 are abutted 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 be ensured to exceed the predetermined range. In addition, in this embodiment, when the controller detects the change of the motor current to control the motor to stop, the first limit switch 253 and the second limit switch 254 are added to further ensure that the motor can stop in time. This dual control method is more secure and reliable.

[0132] When the drum 212 and the bracket 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 bracket in the prior art, the cleaning device needs to be reversed to remove the drum 212, and since the bracket cannot be disassembled from the cleaning device, it is necessary to manually lift the machine to clean the dirt inside the bracket, which brings great inconvenience to the user. For example, if the bracket connected to the drum 212 cannot be disassembled, since the drive motor 112 that drives the drum 212 to rotate is built into the inner cavity of the drum 212, when the bracket is directly cleaned on the cleaning device, the drive motor 112 in the drum 212 may be wetted by water and damaged. In this regard, the body 10 provided in this embodiment has an opening 14 on at least one side of the storage chamber 11 along the first direction, that is, the opening 14 is connected to the storage chamber 11 and is located on at least one side of the storage chamber 11 along the first direction. The opening 14 is located at the lateral position of the body 10 along the first direction. The connecting bracket 23 includes a first bracket 231 and a second bracket 232. The first bracket 231 is installed in the storage cavity 11 and can move along the first direction relative to the body 10. The second bracket 232 is detachably connected to the first bracket 231 and can move along the first direction relative to the first bracket 231 to be taken out from the opening 14. The cleaning member 21 is detachably connected to the second bracket 232 and can move along the first direction relative to the second bracket 232 to be taken out from the opening 14.

[0133] The cleaning member 21 in this embodiment may include a roller 212. When the roller 212 needs to be cleaned, the cleaning member 21 (such as the roller 212) only needs to be removed from the opening 14 along the first direction for cleaning and maintenance. Secondly, since the second bracket 232 adjacent to the cleaning member 21 is easy to hide dirt, when the second bracket 232 needs to be cleaned, the second bracket 232 can be drawn out from the opening 14 of the body 10 along the first direction for cleaning, without the need to reverse the body 10 or lift the bulky body 10 to clean the second bracket 232, which is easy to operate, time-saving and labor-saving. After the cleaning member 21 and the second bracket 232 are cleaned, the second bracket 232 is first moved from the opening 14 along the first direction to the position connected with the first bracket 231, and then the cleaning member 21 is moved from the opening 14 along the first direction to the position connected with the second bracket 232. Secondly, in this embodiment, the cleaning member 21 and the second bracket 232 may be first connected as one, and then the second bracket 232 connected with the cleaning member 21 may be moved along the first direction to a position connected to the first bracket 231, thereby improving the assembly efficiency and convenience when the cleaning member 21 and the second bracket 232 are installed in the main body 10.

[0134] It can be seen that the body 10 of the cleaning device provided in the present application is provided with an opening 14 and a storage chamber 11, and the opening 14 is connected to the storage chamber 11 and is located at least on one side of the storage chamber 11 along the first direction. The cleaning member 21 of the cleaning device is detachably connected to the second bracket 232 and can be moved relative to the second bracket 232 along the first direction to be taken out from the opening 14, and the second bracket 232 is detachably installed in the storage chamber 11 and can be moved relative to the body 10 along the first direction to be taken out from the opening 14. Specifically, the first bracket 231 is installed in the storage chamber 11, and the second bracket 232 is detachably connected to the first bracket 231 and can be moved relative to the first bracket 231 along the first direction to be taken out from the opening 14. In other words, the cleaning member 21 in the present application and the second bracket 232 adjacent to the cleaning member 21 can be respectively extracted from the opening 14 of the body 10 without turning over the machine body 10, which is simple to operate, time-saving and labor-saving, so as to clean and maintain the extracted cleaning member 21 and the second bracket 232 respectively.

[0135] When the cleaning member 21 and the second bracket 232 are disassembled, the cleaning member 21 can be first extracted from the opening 14, and then the second bracket 232 can be extracted from the opening. Alternatively, the cleaning member 21 can be extracted from the opening 14 after the second bracket 232 is extracted from the opening. Alternatively, the second bracket 232 and the cleaning member 21 can be extracted from the opening 14 together, and then the cleaning member 21 can be separated from the second bracket 232 when the second bracket 232 and the cleaning member 21 need to be cleaned separately. In this regard, the extraction method of the cleaning member 21 and the second bracket 232 can be determined according to actual operation requirements, and this embodiment does not make a sole limitation.

[0136] like Figures 11 to 15 As shown, the second bracket 232 of this embodiment is provided with a first sliding space 2321, and the cleaning member 21 can slide in the first sliding space 2321 along a first direction. A first engaging portion 2322 is provided on one of the body 10 (specifically, the first bracket 231 in the body 10) and the second bracket 232. The cleaning mechanism 20 in this embodiment also includes a first locking member 27, which is provided at one end of the cleaning member 21 close to the opening 14. The first locking member 27 has a first locking position in which it is engaged with the first engaging portion 2322 under the action of an external force and a first unlocking position separated from the first engaging portion 2322.

[0137] The first locking member 27 provided in this embodiment can stably and reliably lock the cleaning member 21 in the first sliding space 2321, so as to ensure that the cleaning member 21 will not fall off the body 10 when the cleaning device is working normally. Secondly, the cleaning member 21 can be separated from the first bracket 231 and the second bracket 232 by unlocking the first locking member 27, so that the cleaning member 21 can be extracted from the first sliding space 2321 along the first direction from the opening 14 without reversing the body 10, thereby realizing the lateral extraction of the cleaning member 21 conveniently and quickly. If the cleaning member 21 includes a roller 212, the first locking member 27 can be provided at one end of the roller 212 close to the opening 14, so that the roller 212 is locked in the first sliding space 2321 by the first locking member 27, and when the roller 212 needs to be taken out, the first locking member 27 is unlocked, so that the roller 212 located in the first sliding space 2321 can be extracted from the opening 14.

[0138] Among them, the first engaging portion 2322 is preferably arranged at one end of the second bracket 232 close to the opening 14. Thus, when the cleaning member 21 is extracted from the opening together with the second bracket 232, the cleaning member 21 can be buckled with the first engaging portion 2322 through the first locking member 27 so as to be retained on the second bracket 232, thereby preventing the cleaning member 21 from falling off the second bracket 232 and being damaged. At the same time, after the cleaning member 21 and the second bracket 232 are cleaned separately, the cleaning member 21 can also be buckled with the first engaging portion 2322 on the second bracket 232 through the first locking member 27, so that the cleaning member 21 and the second bracket 232 are installed as one, and then the second bracket 232 and the cleaning member 21 are moved together from the opening along the first direction to the position installed in the storage chamber 11. Compared with the method of installing the second bracket 232 and the cleaning member 21 separately, the assembly efficiency of installing the second bracket 232 and the cleaning member 21 buckled together in the body 10 is higher and the operation is more convenient.

[0139] In addition, 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, it is convenient for the operator to unlock the first locking member 27 and conveniently unlock the first locking member 27 to the first unlocking position separated from the first engaging portion 2322. Moreover, since the cleaning member 21 can slide relative to the second bracket 232 in the first sliding space 2321 along the first direction, the cleaning member 21 located in the first sliding space 2321 can be extracted from the opening 14 by only unlocking the first locking member 27, which can reduce the operating force required for removing and installing the cleaning member 21. When the second bracket 232 is an injection-molded colloid bracket, even if the colloid bracket undergoes a certain deformation, the cleaning member 21 can be smoothly removed from the first sliding space 2321 without using a large force.

[0140] like Fig. 9 , Figures 16 to 23 As shown, the first locking member 27 in this 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 engaging portion 2322. The first locking component 272 can be switched between a first locking position and a 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 engaging 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, slide the cleaning member 21 into the first sliding space 2321 along the first direction, and apply a certain force to the first locking component 272 so that the first locking component 272 is engaged with the first locking portion 2322. The cleaning member 21 can be stably locked in the first sliding space 2321 to prevent the cleaning member 21 from sliding relative to the second bracket 232 or even falling off during the cleaning operation, thereby improving the cleaning effect of the cleaning member 21 on the surface to be cleaned.

[0141] The pop-up component 273 of the first locking member 27 is arranged between the first locking body 271 and the cleaning member 21, wherein when the first locking member 272 is in the first unlocking position, the pop-up component 273 is used to apply elastic force to the first locking body 271 to make the first locking member 27 automatically deviate from the first engaging portion 2322. That is to say, when it is necessary to take out the cleaning member 21 so that the first locking member 272 is in the first unlocking position, the first locking member 27 can automatically deviate from the first engaging portion 2322 under the action of the pop-up 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 prevents the first locking member 272 from being mistakenly fastened with the first engaging portion 2322 again, thereby affecting the removal operation of the cleaning member 21, thereby improving the removal efficiency and operation convenience of the cleaning member 21.

[0142] Combination Figure 8 and Fig.16 It can be seen that in this embodiment, a first installation space 2711 is provided on one side of the first locking body 271 close to the first engaging portion 2322, and the first installation space 2711 includes a first notch 7111 close to the first engaging portion 2322. Specifically, the first locking member 272 includes a first elastic element 2721, a first buckling portion 2722, and a toggle element 2723. One end of the first elastic element 2721 is connected to a side of the first installation space 2711 away from the first notch 7111. The first buckling portion 2722 is connected to one end of the first elastic element 2721 close to the first notch 7111, and the first buckling portion 2722 can at least partially extend out of the first notch 7111 under the elastic force of the first elastic element 2721 to buckle with the first engaging portion 2322. The shifting element 2723 is connected to the first buckling portion 2722 . The shifting element 2723 is used to overcome the elastic force of the first elastic element 2721 to shift the first buckling portion 2722 away from the first engaging portion 2322 .

[0143] When the cleaning member 21 needs to be locked in the first sliding space 2321, the first buckling portion 2722 can be at least partially extended out of the first notch 7111 and buckled with the first clamping portion 2322 at the first locking position under the elastic force of the first elastic element 2721. When the cleaning member 21 needs to be taken out from the first sliding space 2321, the toggle element 2723 can be toggled along the compression direction of the first elastic element 2721 until the toggle element 2723 drives the first buckling portion 2722 to move to the first unlocking position separated from the first clamping portion 2322, which is simple and convenient to operate. Of course, when the first buckling portion 2722 is located at the first unlocking position, although the cleaning member 21 can also be pulled out of the first sliding space 2321 along the first direction at this time, if the toggle element 2723 is accidentally released, the first buckling portion 2722 may be buckled with the first clamping portion 2322 again under the elastic force of the first elastic element 2721. In this regard, since the pop-up component 273 provided in this embodiment will apply an elastic force to the first locking body 271, when the first buckling portion 2722 is in the first unlocking position, the first locking component 272 will be bounced open to a position deviating from the first engaging portion 2322 along with the first locking body 271 under the action of the elastic force of the pop-up component 273, so that there is a certain distance between the first locking component 272 and the first locking body 271 and the first bracket 231 and the second bracket 232. Even if the toggle element 2723 is released to extract the cleaning piece 21, the first buckling portion 2722 will not return to the first locking position, thereby making it convenient to grasp the first locking component 27 to extract the cleaning piece 21.

[0144] like Fig.15 As shown, the first installation space 2711 on the first locking body 271 further includes a second notch 7112, which is located on a side of the first notch 7111 away from the first engaging portion 2322 and on a side of the first locking body 271 close to the opening 14 of the body 10. Fig.19As shown, the toggle element 2723 in this embodiment includes a connecting block 7231 and a toggle block 7232. The connecting block 7231 is located in the first installation space 2711 and connected to the first buckle portion 2722. The toggle block 7232 is connected to the connecting block 7231 and is located outside the second notch 7112. The toggle block 7232 is used to toggle the first buckle portion 2722 to move in the first installation space 2711 along the compression direction of the first elastic element 2721, so as to move the first buckle portion 2722 to the first unlocking position separated from the first engaging portion 2322. Since the toggle block 7232 is located outside the second notch 7112 and close to the opening 14, it is convenient for the operator to toggle the toggle block 7232 to separate the cleaning member 21 from the first bracket 231 and the second bracket 232, so as to perform the extraction operation of the cleaning member 21. The outer surfaces of the connecting block 7231 and the toggle block 7232 away from the first installation space 2711 are both provided with a plurality of protrusions, which can increase the friction force when a hand touches the connecting block 7231 and the toggle block 7232 , making it easier to toggle the toggle element 2723 .

[0145] Specifically, combined Fig.10 , Fig.17 It can be seen that in this embodiment, a first groove 2323 is provided on one side of the second bracket 232 close to the first locking member 272, and the first engaging portion 2322 is disposed in the first groove 2323. The first locking body 271 includes a connecting plate 2712 and a mounting cover 2713. One side of the connecting plate 2712 is connected to the cleaning member 21, and the other side of the connecting plate 2712 is disposed opposite to the second bracket 232. The mounting cover 2713 is buckled and covered on one side of the connecting plate 2712 opposite to the second bracket 232 and is surrounded between the connecting plate 2712 to form a first mounting space 2711, and the outer shape of the mounting cover 2713 is adapted to the inner wall surface of the first groove 2323. Therefore, when the first locking component 272 is buckled with the first locking portion 2322 on the second bracket 232 to lock the cleaning member 21 in the first sliding space 2321, the installation cover 2713 where the first installation space 2711 is located can be embedded in the first groove 2323 to buckle the first locking portion 2722 of the first locking component 272 with the first locking portion 2322 in the first groove 2323. This not only makes the assembly structure between the cleaning member 21 and the second bracket 232 more compact and stable, but also reduces the distance between the cleaning member 21 and the corner areas of the wall, further improving the cleaning coverage rate when the cleaning member 21 extends out of the main body 10 for edge cleaning.

[0146] In this embodiment, one of the first engaging portion 2322 and the first buckle portion 2722 may include a convex structure, and the other may include a groove structure. To this end, the shapes of the first engaging portion 2322 and the first buckle portion 2722 may be specifically set according to actual design requirements, and this embodiment does not make a sole limitation here. In a specific embodiment of the utility model, if Fig.10 As shown, the first engaging portion 2322 may include a first buckling groove 3221. In this case, the first buckling portion 2722 may include a buckling block 7221 and an inserting tongue 7222. The buckling block 7221 is located in the first installation space 2711 and is connected to the first elastic element 2721 and the toggle element 2723. The size of the buckling block 7221 is larger than the size of the first notch 7111, so as to limit the buckling block 7221 in the first installation space 2711, and avoid the buckling block 7221 protruding from the first installation space 2711, which increases the difficulty of buckling operation. The plug tongue 7222 is located on one side of the buckle block 7221 close to the first notch 7111 and is arranged opposite to the first notch 7111. The size of the plug tongue 7222 is smaller than the size of the first notch 7111 and is adapted to the first buckle groove 3221, so that the plug tongue 7222 can be pushed by the buckle block 7221 to the first locking position plugged into the first buckle groove 3221 under the elastic force of the first elastic element 2721. When the cleaning member 21 needs to be unlocked for extraction, the toggle element 2723 is toggled in a direction away from the first buckle groove 3221 to separate the plug tongue 7222 from the first buckle groove 3221. In this embodiment, the buckling method of inserting the plug tongue 7222 into the first buckle groove 3221 is not only convenient to operate, but also easy to process, so as to reduce the difficulty of assembling the cleaning member 21 and the second bracket 232. The first elastic element 2721 in this embodiment is preferably a compression spring, which is cheap and easy to install.

[0147] like Fig.21 and Fig. 22As shown, the pop-up component 273 in this embodiment includes a connecting body 2731, a connecting shaft 2732 and a second elastic element 2733. The connecting body 2731 is connected to the cleaning member 21. The connecting shaft 2732 is installed on the connecting body 2731. The first locking body 271 is connected to 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 the cleaning member 21 needs to be locked in the first sliding space 2321 through the first locking member 27, the first locking body 271 can be pushed to overcome the elastic force of the second elastic element 2733 and rotate around the axis of the connecting shaft 2732 to approach the first groove 2323 until the installation cover 2713 of the first locking body 271 is located in the first groove 2323 and the first buckling portion 2722 is buckled with the first engaging portion 2322. When it is necessary to extract the cleaning piece 21, the pushing element 2723 is pushed along the compression direction of the first elastic element 2721 to separate the first buckling portion 2722 from the first engaging portion 2322. The first locking body 271 can be rotated around the axis of the connecting shaft 2732 to a position away from the second bracket 232 under the elastic force of the second elastic element 2733. At this time, the operator can take the first locking body 271 and extract the cleaning piece 21 from the first sliding space 2321 along the first direction. The operation is simple and convenient, and the operator can take out the cleaning piece 21 without having to reach deep into the storage cavity 11 to grab the cleaning piece 21.

[0148] The second elastic element 2733 may include a torsion spring (eg Fig. 22 As shown). The torsion spring is sleeved on the connecting shaft 2732 and abuts between the connecting body 2731 and the first locking body 271, so that the first locking body 271 is bounced to a position separated from the second bracket 232 by the torsion spring. In addition, in order to improve the connection reliability between the torsion spring and the connecting body 2731 and the first locking body 271, and to prevent the torsion spring from being separated from the original position under the action of its own elastic force after being bounced and affecting the secondary locking of the cleaning member 21, a first connecting hole 7311 is provided at one 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 prevent the torsion spring from sliding along the axis of the connecting shaft 2732 to other positions where it is difficult to abut the connecting body 2731 and the first locking body 271 at the same time.

[0149] Specifically, Figures 11 to 15As shown, the cleaning member 21 in this embodiment includes a driving member 211 and a roller 212. Specifically, the driving member 211 is fixed to one end of the first bracket 231 in the body 10 along the first direction and is located in the first sliding space 2321 (i.e., located on the side of the second bracket 232 away from the first bracket 231). The roller 212 is detachably mounted on the driving member 211 and can rotate around its own axis under the drive of the driving member 211. The driving member 211 in this embodiment may include a mounting seat 111, a driving motor 112, a second bearing 113 and a connector 114. The mounting seat 111 is fixedly connected to one end of the first bracket 231 away from the first locking member 27 of the cleaning member 21, the driving motor 112 is connected to the mounting seat 111, the connector 114 is connected to the rotating shaft of the driving motor 112, and the second bearing 113 is mounted on the mounting seat 111 and is located on the side of the driving motor 112 away from the connector 114 along the first direction. A connecting structure (such as a groove and / or a protrusion, etc.) that is compatible with the connecting head 114 is provided inside the drum 212. The drum 212 is movably mounted on the driving component 211 (at this time, the second bearing 113, the driving motor 112 and the connecting head 114 are all located inside the drum 212). The driving motor 112 rotates to drive the drum 212 to rotate around its own axis through the connecting head 114. The drum 212 achieves efficient cleaning of the surface to be cleaned during the rotation process.

[0150] like Fig.16 As shown, the first locking member 27 in this embodiment further includes a supporting member 274, which is inserted into the drum 212 and located at one end of the drum 212 away from the driving member 211 along the first direction. The supporting member 274 is connected to the connecting body 2731 and can rotate relative to the connecting body 2731 around the axis of the drum 212, so that the first locking body 271 connected to the connecting body 2731 will not interfere with the rotational movement of the drum 212. At the same time, the supporting member 274 and the driving member 211 are inserted into the opposite ends of the drum 212 along the length direction of the drum 212 to support the opposite ends of the drum 212, so that the opposite ends of the drum 212 along the first direction are not in a suspended state, which can improve the stability of the drum 212 during rotation and movement.

[0151] Specifically, Fig.21 and Fig.23As shown, a second groove 2741 is provided on one side of the support member 274 close to the connecting body 2731, and the connecting body 2731 is disposed in the second groove 2741 and is rotatably connected to the support member 274. Since the connecting body 2731 can rotate relative to the support member 274, during the rotation of the drum 212, the support member 274 connected to the connecting body 2731 can rotate with the drum 212, thereby not interfering with the rotation of the drum 212, thereby improving the stability of the drum 212 during movement and / or rolling. In addition, since the connecting body 2731 is disposed in the second groove 2741 of the support member 274, the structure of the entire first locking member 27 can be made more compact and reliable. Furthermore, when the support component 274 is passed through the drum 212 to support the drum 212, the connector 2731 of the first locking member 27 will not increase the distance between the drum 212 and the wall along the first direction, thereby reducing the cleaning blind spot while supporting the drum 212 through the support component 274, so that the drum 212 can be cleaned along the edge, thereby improving the cleaning coverage of the drum 212.

[0152] like Fig. 22 As shown, a third groove 7312 is provided on one side of the connecting body 2731 away from the first locking body 271. Fig.23 As shown, the support component 274 includes a support body 2742, a convex column 2743 and a first bearing 2744. The support body 2742 is inserted into the drum 212 and abuts against the inner wall surface of the drum 212, and the second groove 2741 is arranged on the side of the support body 2742 close to the connecting body 2731. The support body 2742 may include a cylindrical structure or a prismatic structure, and may specifically include a cylindrical tube structure adapted to the inner wall surface of the drum 212, so that the support body 2742 is inserted into the drum 212 to support the drum 212 while avoiding interference with the rotation of the drum 212 when the first locking member 27 is buckled with the second bracket 232. The convex column 2743 is arranged at the bottom of the second groove 2741 in the support body 2742. The inner circumference of the first bearing 2744 is fixed on the convex column 2743 and is located in the third groove 7312, and the outer circumference of the first bearing 2744 is connected to the inner wall surface of the third groove 7312. During the rotation of the drum 212 , the drum 212 will drive the support body 2742 to rotate together. Since the connecting body 2731 is rotatably connected to the support body 2742 via the first bearing 2744 , the first locking body 271 connected to the connecting body 2731 will not interfere with the rotational movement of the drum 212 .

[0153] like Fig.12 and Fig.15As shown, the first bracket 231 of this embodiment is installed in the storage chamber 11 through the installation bracket 24, and the first bracket 231 is provided with a second sliding space 2311, and the second bracket 232 can slide in the second sliding space 2311 along the first direction. In this regard, in order to improve the stability of the second bracket 232 after slidingly installed in the second sliding space 2311, the cleaning mechanism 20 provided in this embodiment also includes a sliding connection component 28, and the sliding connection component 28 is arranged between the first bracket 231 and the second bracket 232. The second bracket 232 has a first sliding position connected to the second sliding space 2311 by the sliding connection component 28 under the action of an external force, and a second sliding position separated from the first bracket 231.

[0154] It can be seen that in this embodiment, the second bracket 232 can be slidably installed in the second sliding space 2311 of the first bracket 231 through the sliding connection component 28. When the second bracket 232 needs to be taken out for cleaning and maintenance, the second bracket 232 is pulled relative to the first bracket 231 to slide out from the opening 14 of the body 10 along the first direction. When the second bracket 232 needs to be installed back into the second sliding space 2311, the second bracket 232 is pushed to move into the second sliding space 2311 along the first direction and connected to the first sliding position in the second sliding space 2311 through the sliding connection component 28. It can be seen that in this embodiment, the second bracket 232 is slidably connected to the second sliding space 2311 through the sliding connection component 28, which improves the convenience of extracting and installing the second bracket 232.

[0155] The sliding connection assembly 28 includes a slide groove 281 and a sliding boss 282. The slide groove 281 is arranged on at least one side of the second sliding space 2311 along the third direction. The sliding boss 282 is arranged on one side of the second bracket 232 close to the first bracket 231 and is arranged one-to-one with the slide groove 281. Therefore, when the second bracket 232 is installed in the second sliding space 2311, the sliding boss 282 is slidably inserted into the slide groove 281 in the second sliding space 2311. When the second bracket 232 needs to be extracted, the second bracket 232 is pulled along the first direction until the sliding boss 282 is separated from the slide groove 281. Of course, the slide groove 281 in this embodiment can also be set on the side of the second bracket 232 close to the first bracket 231, and the sliding boss 282 can be set in the second sliding space 2311, or the sliding boss 282 and the slide groove 281 can be set on both the second bracket 232 and the first bracket 231 at the same time to stably slide and connect the second bracket 232 in the second sliding space 2311.

[0156] In another embodiment of the present invention, regardless of whether the cleaning member 21 can be extracted from the opening 14 of the main body 10, in order to solve the problem that the bracket in the prior art cannot be removed from the sweeping machine, resulting in that the garbage on the bracket will be difficult to clean, without turning over the sweeping machine, this embodiment can also allow only the second bracket 232 arranged adjacent to the drum 212 to be extracted from the side of the main body 10.

[0157] In order to make the second bracket 232 removable separately, the cleaning device in this embodiment includes a body 10 and a cleaning mechanism 20. The body 10 is provided with an opening 14 and a storage chamber 11. The opening 14 is communicated with the storage chamber 11 and is located at least on one side of the storage chamber 11 along the first direction. The cleaning mechanism 20 includes a cleaning member 21 and a second bracket 232. The cleaning member 21 is installed in the storage chamber 11 and a second sliding space 2311 is formed between the cleaning member 21 and the body 10. The second bracket 232 is detachably connected to 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 taken out from the opening 14.

[0158] It can be seen that, since the cleaning member 21 of the cleaning device is installed in the storage cavity 11 and the second sliding space 2311 is formed between the cleaning member 21 and the body 10, the second bracket 232 is detachably connected to the body 10 and is located in the second sliding space 2311, and the second bracket can slide in the second sliding space 2311 along the first direction to be taken out from the opening. In other words, the second bracket 232 in this embodiment can be taken out from the opening of the body 10 without turning over the machine body 10, which is simple to operate, saves time and effort, and is convenient for cleaning and maintenance of the extracted second bracket 232, ensuring that the garbage and dirt on the second bracket 232 can be fully cleaned.

[0159] 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 to the second sliding space 2311, and to prevent the second bracket 232 from being separated from the first bracket 231 by external force, a second engaging portion is further provided on the first bracket 231 of the body 10 in this embodiment. Fig.12 , Figure 24 to Figure 26 As shown, the cleaning mechanism 20 further includes a second locking member 29, which is disposed at one end of the second bracket 232 close to the opening 14, and has a second locking position where the second locking member 29 is engaged with the second engaging portion by an external force and a second unlocking position where the second locking member 29 is separated from the second engaging portion. Thus, when the second bracket 232 is connected to the second sliding space 2311, the second bracket 232 can be fixed to the first bracket 231 by the second locking member 29 to prevent the second bracket 232 from sliding off the first bracket 231.

[0160] It can be seen that the second locking member 29 provided on the second bracket 232 of this embodiment 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 when the cleaning device is working normally, thereby improving the stability and firmness of the connection between the second bracket 232 and the first bracket 231. When it is necessary to remove the second bracket 232, the second locking member 29 can be unlocked to separate the second bracket 232 from the first bracket 231, so that the second bracket 232 can be extracted 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 from the side without inverting the body 10.

[0161] 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, it is convenient for the operator to unlock the first locking member 27 and conveniently unlock the second locking member 29 to the second unlocking position separated from the second engaging portion. In addition, since the second bracket 232 can slide relative to the first bracket 231 in the second sliding space 2311 along the first direction, after the second locking member 29 is unlocked, the second bracket 232 located in the second sliding space 2311 can be extracted from the opening 14, which improves the convenience of removing and installing the second bracket 232.

[0162] Specifically, when the cleaning mechanism 20 in this embodiment further includes a first bracket 231, the first bracket 231 is installed in the storage cavity 11, the cleaning member 21 is connected to the first bracket 231 through the driving member 211 and is surrounded with the first bracket 231 to form a second sliding space 2311, the second clamping portion is provided on the first bracket 231, and the second bracket 232 is buckled with the second clamping portion through the second locking member 29 to be locked in the second sliding space 2311. Therefore, after the second bracket 232 is taken out and cleaned, when the second bracket 232 is slid into the second sliding space 2311 along the first direction, the second locking member 29 is buckled with the second clamping portion on the first bracket 231, so that the second bracket 232 is firmly and reliably held in the second sliding space 2311, so that the second bracket 232 is not easy to slide out of the second sliding space 2311.

[0163] The second locking member 29 in this embodiment includes a second locking body 291 and a second buckling portion 292. The second buckling portion 292 is movably connected to the second locking body 291 to buckle with the second engaging portion, and the second buckling portion 292 can be switched between a second locking position and a second unlocking position under the action of an external force. When the second bracket 232 needs to be extracted from the body 10 for cleaning and maintenance, a certain force can be applied to the second buckling portion 292 to separate the second buckling portion 292 from the second engaging portion, so as to pull the second bracket 232 out of the second sliding space 2311. When the second bracket 232 needs to be installed in the second sliding space 2311, after sliding the second bracket 232 along the first direction to connect to the second sliding space 2311 through the sliding connection assembly 28, a certain force is applied to the second buckling portion 292 to buckle the second buckling portion 292 with the second locking portion, so that the second bracket 232 can be stably locked in the second sliding space 2311, preventing the second bracket 232 from sliding relative to the first bracket 231 or even falling off during the cleaning operation of the cleaning member 21, thereby improving the firmness and stability of the connection between the second bracket 232 and the first bracket 231.

[0164] like Fig.10 As shown, a fourth groove 2324 is provided at one end of the second bracket 232 close to the opening 14, and the fourth groove 2324 is offset from the first bracket 231 along the second direction. Fig.26 As shown, the second locking body 291 is installed in the fourth groove 2324 to avoid increasing the installation space between the first bracket 231 and the second bracket 232 due to the existence of the second locking body 291, so that the overall structure of the cleaning mechanism 20 installed in the storage chamber 11 is more compact, and the structural strength of the cleaning mechanism 20 is improved. Moreover, the fourth groove 2324 is located on one side of the first groove 2323 along the third direction, and the two are adjacently arranged, which is convenient for processing and improves the compactness of the structure of the second bracket 232.

[0165] Specifically, combined Figure 24 to Figure 26It can be known that the second locking body 291 of the second locking member 29 of this 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 bracket 232 and is surrounded by the second bracket 232 to form a second installation space. Specifically, the cover plate 911 is buckled on the fourth groove 2324 and is surrounded by the fourth groove 2324 to form a second installation space. The second installation space is provided with a first connection opening 9111 and a second connection opening 9112, the first connection opening 9111 is located on one side of the second installation space along the third direction, and the second connection opening 9112 is located on one side of the second installation space close to the second clamping portion. The pressing block 912 includes a pressing portion 9121 and a main body portion 9122. The main body 9122 is located in the second installation space, and the pressing portion 9121 is connected to one side of the main body 9122 close to the first connecting opening 9111 and is located outside the second installation space, that is, the pressing portion 9121 is located at the bottom of the second bracket 232 along the third direction, which not only can reduce the lateral length of the second bracket 232 along the first direction, but also makes it convenient for the operator to reach out and press the pressing portion 9121 along the third direction to unlock the second buckle portion 292.

[0166] The second buckle portion 292 is connected to the side of the main body 9122 close to the second connection opening 9112 and buckled with the second clamping portion. The third elastic element 913 is connected between the side of the main body 9122 away from the pressing portion 9121 and the inner wall surface of the second installation space. When the second bracket 232 needs to be extracted, the pressing portion 9121 can be pressed to overcome the elastic force of the third elastic element 913 to push the main body 9122 to drive the second buckle portion 292 and the second clamping portion to separate. When the second bracket 232 needs to be locked in the second sliding space 2311, the second buckle portion 292 can be buckled with the second clamping portion.

[0167] Specifically, see Fig.26 The first bracket 231 is provided with a third connection opening 2313 near the second buckling portion 292, and the third connection opening 2313 is connected to the second connection opening 9112. The second engaging portion includes a second buckling groove 2312 (such as Fig.12As shown in the figure, the second buckle groove 2312 is arranged on one side of the third connection opening 2313 along the third direction. At this time, the second buckle portion 292 includes a buckle protrusion structure adapted to the second buckle groove 2312, and the width of the second buckle portion 292 along the third direction is smaller than the width of the third connection opening 2313 along the third direction, so that the second buckle portion 292 can move along the third direction under the pushing action of the pressing block 912 to leave the second buckle groove 2312 to achieve unlocking. The third elastic element 913 includes a spring, the axis of which is parallel to the third direction and connected to the main body 9122 of the pressing block 912 and the side of the second installation space away from the main body 9122 along the third direction. Therefore, when the second bracket 232 needs to be locked in the second sliding space 2311, the distance between the pressing portion 9121 of the pressing block 912 and the third connection port along the third direction is adjusted until the second buckle portion 292 can enter the third connection port and buckle with the second buckle groove 2312 under the elastic force of the third elastic element 913. When the second bracket 232 needs to be taken out, the pressing portion 9121 is pushed along the compression direction of the third elastic element 913 to separate the second buckle portion 292 from the second buckle groove 2312, and the second bracket 232 can be drawn out along the first direction.

[0168] like Fig.26 As shown, in order to improve the stability and accuracy of the pressing block 912 in the process of pushing and pulling the second buckling portion 292, the second locking member 29 in this embodiment also includes a guide component 293, and the guide component 293 is arranged in the second installation space. The guide component 293 includes a first guide member and a second guide member. The first guide member is arranged on the main body 9122, and the second guide member is arranged on the second bracket 232. The first guide member cooperates with the second guide member to guide the main body 9122 to move relative to the second bracket 232 along the telescopic direction of the third elastic element 913, so as to avoid the main body 9122 deviating from the predetermined trajectory during the process of the pressing portion 9121 pushing the main body 9122 to move, making it difficult for the second buckling portion 292 to buckle with the second buckling groove 2312, thereby improving the stability of the main body 9122 during the movement.

[0169] Specifically, the first guide member in this embodiment includes a guide hole 931 that penetrates the main body 9122 along the second direction, and the second guide member includes 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 compatible with the size of the guide hole 931 along the first direction, and the fixed shaft 932 is penetrated in the guide hole 931 and connected to the cover plate 911. Therefore, through the cooperation between the guide hole 931 and the fixed shaft 932, not only can the main body 9122 be guided to overcome the stability of the third elastic element 913 when moving along the third direction, but also the moving distance of the main body 9122 can be limited.

[0170] It can be seen that the cleaning device provided in this embodiment can extract the cleaning member 21 and the second bracket 232 respectively. When the cleaning member 21 and the second bracket 232 are both installed in the storage chamber 11 of the body 10 to perform cleaning work under the drive of the cleaning device, the cleaning member 21 can be driven by the first driving component 22 to move along the first direction to the first position so as to extend the body 10 to the corner of the wall for edge cleaning. Since the cleaning member 21 in the first position is flush with the straight line 13 passing through the vertex 12 or even exceeds the straight line 13, the part of the cleaning member 21 extending out of the body 10 can clean all areas between the outer edge of the body 10 and the wall surface, and there will be no situation where there is a cleaning blind spot between the body 10 and the wall surface even if the cleaning member 21 expands outside the body 10, thereby improving the cleaning coverage of the cleaning device on the surface to be cleaned. When the cleaning device travels to a place where there is no corner area for cleaning, the cleaning member 21 can be driven by the first driving component 22 to retract into the storage chamber 11 of the body 10. If the cleaning member 21 is a roller 212, the roller 212 retracted into the storage chamber 11 cleans the surface to be cleaned along the driving path of the cleaning device. When encountering a corner area, the first driving assembly 22 drives the roller 212 to move to the first position extending out of the body 10 to clean the edge. Since the end of the roller 212 at the first position close to the wall is flush with or beyond the straight line 13 passing through the vertex 12 of the body 10, the roller 212 can fully clean the area between the outer peripheral edge of the body 10 and the wall, thereby improving the cleaning coverage of the roller 212.

[0171] When the cleaning device in this embodiment further includes a sewage tank 40, a clean water tank 30 and a wiper 50, the sewage tank 40 is arranged on the body 10 and located on a side of the cleaning member 21 away from the second bracket 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 a side of the cleaning member 21 away from the ground along the third direction, so that the clean water and / or cleaning liquid in the clean water tank 30 can be transmitted to the cleaning member 21 through a pipeline at a close distance to wet the cleaning member 21.

[0172] The wiper 50 is connected to the second bracket 232 and abuts against the surface of the cleaning member 21. The wiper 50 is used to scrape the sewage on the cleaning member 21 and then transport it to the sewage tank 40 for temporary storage. In the process of scraping the sewage by the conventional wiper 50, the garbage on the cleaning member 21 will be deposited on the side of the wiper 50 close to the cleaning member 21. Since the wiper 50 is difficult to be disassembled from the cleaning device, it is also difficult to clean the garbage from the wiper 50. In this regard, since the wiper 50 is connected to the second bracket 232 in this embodiment, when the second bracket 232 is extracted, the wiper 50 can be extracted along with the second bracket 232, so that the extracted wiper 50 can be fully cleaned conveniently, the operation is convenient, and the cleaning effect of the wiper 50 is good.

[0173] See also Fig. 9 and Fig.10 In this embodiment, a water supply channel 2325 and a plurality of water spray ports 2326 are also provided in the second bracket 232. The water supply channel 2325 is laid in the second bracket 232 along the first direction. The water spray ports 2326 are provided on a side of the second bracket 232 close to the cleaning member 21 and are connected to the water supply channel 2325, and at least one or more water spray ports 2326 are provided opposite to at least a portion of the cleaning member 21 extending out of the body 10. When water and / or cleaning liquid is introduced into the water supply channel 2325, the water and / or cleaning liquid can be sprayed onto the cleaning member 21 located in the first sliding space 2321 of the second bracket 232 through the water spray ports 2326, so that the cleaning member 21 is fully soaked and self-cleaned to better clean the surface to be cleaned, thereby improving the cleaning effect and cleaning efficiency of the cleaning member 21 on the surface to be cleaned. Water and / or cleaning liquid can be stored in the clean water tank 30, and the clean water tank 30 is connected to the water supply channel 2325 through a connecting pipe 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 ports 2326 are arranged opposite to at least the portion of the cleaning member 21 extending out of the body 10 or even beyond the vertex 12, when the cleaning member 21 is cleaning along the edge, the portion of the cleaning member 21 beyond the vertex 12 can also be soaked and self-cleaned to achieve better cleaning effect and cleaning efficiency. A sealing cover 2327 is arranged on the second bracket 232, and the sealing cover 2327 is covered on the water supply channel 2325. A water receiving nozzle 2328 connected to the water supply channel 2325 is arranged on the sealing cover 2327, and the water receiving nozzle 2328 can be connected to the clean water tank 30 through a connecting pipe, so that the clean water and cleaning liquid in the clean water tank 30 can enter the water supply channel 2325 along the water receiving nozzle 2328.

[0174] When the existing wiper 50 scrapes the sewage on the cleaning member 21 and discharges the sewage into the sewage tank 40, the garbage on the cleaning member 21 will also be discharged into the sewage tank 40 from the drainage port 53 on the wiper 50. Such garbage may block the sewage inlet of the sewage tank 40, thereby reducing the sewage collection efficiency of the sewage tank 40 or causing the sewage to overflow from the sewage tank 40 and cause secondary pollution to the surface to be cleaned. Fig. 27 and Fig.28 In this embodiment, the wiper plate 50 of the cleaning device includes a plate body 51, and the plate body 51 is connected to the connecting bracket 23. Specifically, the plate body 51 is connected to the second bracket 232. The plate body 51 has a first side surface 511 and a second side surface 512 arranged opposite to each other. The plate body 51 is provided with a wiper portion 52, a drain port 53 and a filtering structure. The wiper portion 52 is convexly arranged on the first side surface 511 and is located at the side edge of the drain port 53 along the second direction. The wiper portion 52 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 arranged 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, and then guide the sewage from the second side surface 512 to the sewage tank 40. The filtering structure is covered in the drain port 53, so that in the process of the drain port 53 guiding the sewage to the second side surface 512, the garbage can be filtered through the filtering structure. The garbage filtered out by the filtering structure will not enter the sewage tank 40, so as to improve the sewage collection efficiency of the sewage tank 40 and prevent the sewage from flowing to the ground and causing secondary pollution due to failure to be collected by the sewage tank 40 in time.

[0175] The filtering structure in this embodiment may specifically include a filter net disposed in the drain port 53, or may include a plurality of micro-filter holes 54 whose size is smaller than that of the drain port 53. When the flow structure includes a plurality of filter holes 54, the plurality of filter holes 54 may be distributed and disposed on the plate body 51 and penetrate the plate body 51. At this time, the filter holes 54, while playing the role of filtering garbage, also serve as the drain port 53 to guide the sewage from the first side 511 to the second side 512, and then discharge the sewage into the sewage tank 40. The second side 512 is provided with a water outlet 55 on one side away from the first bracket 231 along the second direction, and the sewage guided to the second side 512 by the filter holes 54 flows into the sump 42 of the sewage tank 40 from the water outlet 55. Moreover, the axis of the filter hole 54 may be inclined toward 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 sewage tank 40 from the water outlet 55.

[0176] The water outlet 55 in this embodiment can be set in the middle area of ​​the plate body 51. However, in some embodiments of the utility model, since the wiper 50 needs to extend out of the body 10 with the cleaning member 21 to clean the 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 50 extends out of the body 10 with the cleaning member 21. The side of the plate body 51 that can extend out of the body 10 is the extension side, and in this embodiment, the water outlet 55 can be set on the side of the plate body 51 away from the extension side. Specifically, the distance from the water outlet 55 to one end of the plate body 51 along the first direction can be made smaller than the distance from the water outlet 55 to the other end of the plate body 51 along the first direction. Thus, even if the end of the plate body 51 along the first direction farther from the water outlet 55 extends out of the main body 10, it can be ensured that the water outlet 55 can correspond to the water collecting trough 42, so that the sewage scraped off the cleaning member 21 by the wiper 50 is discharged into the water collecting trough 42, thereby preventing the sewage discharged from the water outlet 55 of the wiper 50 from falling to the ground when the cleaning member 21 extends out of the main body 10.

[0177] The length of the plate body 51 in this embodiment extends along 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 this embodiment. In this regard, in order to improve the filtering efficiency of the sewage scraped off by the wiper 52, the multiple filter holes 54 in this embodiment are arranged in at least one row (such as one row, two rows, three rows, four rows, etc.) along the length direction of the plate body 51, so as to filter the sewage through at least one row of multiple filter holes 54 at the same time, thereby improving the filtering efficiency of the sewage. The filtered garbage is either retained in the space formed between the wiper 52 and the flow hole, or falls directly to the ground. When the garbage falls to the ground, it can be cleaned for the second time by the middle sweeping assembly 80 of the cleaning device and collected in the dust box 70. Because most of the garbage has been cleaned and collected by the side brush assembly 60, the middle sweep assembly 80, etc. before the cleaning member 21 cleans the surface to be cleaned, the garbage on the cleaning member 21 is generally not too much and the volume is also small. Therefore, the garbage scraped from the cleaning member 21 by the wiper portion 52 can be temporarily retained in the space between the wiper portion 52 and the filter hole 54. Since the second bracket 232 is detachable and removable, when the second bracket 232 is taken out, the wiper plate 50 connected to the second bracket 232 can also be taken out, so that the garbage remaining on the first side 511 of the removed wiper plate 50 can be cleaned.

[0178] The filter hole 54 in the present embodiment may include at least one of a circular hole, a square hole, and a diamond hole. The maximum width of the filter hole 54 is not less than 1 mm and not more than 2 mm, that is, the maximum width of the filter hole 54 may 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 by filtering under the above-mentioned size range. The filter hole 54 in the present embodiment is preferably a circular hole, which is easy to process. When the filter hole 54 includes a circular hole, the maximum width is the diameter of the filter hole 54, that is, the diameter of the filter hole 54 is not less than 1 mm and not more than 2 mm. The minimum spacing between two adjacent filter holes 54 is not less than 1 mm, and the maximum spacing between two adjacent filter holes 54 is not greater than 2 mm, that is, the spacing between two adjacent filter holes 54 is between 1 mm and 2 mm, and the spacing between two adjacent filter holes 54 may 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 two adjacent filter holes 54 is too small (such as less than 1 mm), the structural strength of the wiper portion 52 will be reduced, and if the spacing is too large, the filtration efficiency of the garbage will be poor. Therefore, in this embodiment, the spacing between two adjacent filter holes 54 is set within the above range, which can not only ensure the structural strength of the wiper plate 50, but also improve the filtration efficiency of the filtration structure for garbage.

[0179] like Fig.29 and Fig.30As shown, the sewage tank 40 provided in this embodiment is arranged on the body 10 and is located on the side of the cleaning member 21 away from the connecting bracket 23. The sewage tank 40 includes a box body 41 and a water collecting tank 42. A liquid storage chamber 411 is arranged in the box body 41, and a suction channel 412 connected to the liquid storage chamber 411 is arranged on the top of the box body 41. The liquid storage chamber 411 includes a top surface 4111, and the top surface 4111 is the top inner cavity wall of the liquid storage chamber 411 close to the clean water tank 30 along the third direction. The water collecting tank 42 is arranged outside the box body 41 and is located below the wiper 50. The water collecting tank 42 is used to collect the sewage scraped from the cleaning member 21 by the wiper 50. A connecting channel 43 is arranged between the water collecting tank 42 and the liquid storage chamber 411, and a predetermined distance is provided between the port where the connecting channel 43 communicates with the water collecting tank 42 and the top surface 4111. In this embodiment, the suction channel 412 of the sewage tank 40 can be connected to the negative pressure device, and the negative pressure device is used to pump negative pressure into the liquid storage chamber 411 so that the air pressure of the liquid storage chamber 411 is lower than the air pressure of the water collection tank 42. After a certain amount of sewage in the water collection tank 42 is collected, when the air pressure of the liquid storage chamber 411 is lower than the air pressure of the water collection tank 42, the sewage will enter the liquid storage chamber 411 along the connecting channel 43 for storage. Since the liquid storage chamber 411 is a relatively closed structure, and there is a predetermined distance between the port connecting the connecting channel 43 and the water collection tank 42 and the top surface 4111, when the cleaning device body 10 is turned over or shaken with great intensity, the sewage tank 40 is not prone to water spillage and leakage, thereby preventing the sewage from flowing out to cause secondary pollution or even damage the electrical components in the cleaning device.

[0180] like Figure 6 As shown, the negative pressure extraction device in this embodiment may specifically include a first vacuum pump 44 and an air circuit connecting pipe 45. The first vacuum pump 44 is installed in the body 10 and is located on one side of the dust box 70. The air circuit connecting pipe 45 is connected between the air suction port of the first vacuum pump 44 and the suction channel 412. By starting the first vacuum pump 44, the liquid storage chamber 411 of the sewage tank 40 can be vacuumed, so that the sewage in the water collection tank 42 is collected into the liquid storage chamber 411 in time to prevent the sewage from spilling and avoid secondary pollution. Specifically, since the sewage tank 40 is installed on one side of the cleaning member 21 through the mounting shell 15 of the body 10, the mounting shell 15 is provided with a second connection hole 151 adapted to the air circuit connecting pipe 45 at a position close to the suction channel 412 of the sewage 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 air tightness between the air circuit connecting pipe 45 and the suction channel 412 during the process of pumping negative pressure.

[0181] In addition, the mounting bracket 24 in this embodiment is rotatably connected to the main body 10 and can rotate in a direction away from the surface to be cleaned. Moreover, a torsion spring is abutted between the mounting bracket 24 and the main body 10. The torsion spring can apply a force toward the surface to be cleaned to the mounting bracket 24, so that when the cleaning member 21 is working normally, the mounting bracket 24 can better abut against the surface to be cleaned under the thrust of the torsion spring, thereby improving the cleaning force of the cleaning member 21 when cleaning the surface to be cleaned. The cleaning device also includes a lifting rope 243 and a mounting block 242. One end of the lifting rope 243 is connected to a fixing block, and the other end of the lifting rope 243 will be connected to a second driving assembly provided in the main body 10. The mounting block 242 is provided on the mounting bracket 24 and has a gap with the mounting bracket 24. See Fig.31 and Fig.32 , a side of the mounting block 242 close to the mounting bracket 24 is provided with an abutment groove 2421, and a strip opening groove 2422 for the lifting rope 243 to pass through is also provided on the mounting block 242. The strip opening groove 2422 is communicated with the abutment groove 2421, and the fixing block is adapted to the inner wall surface of the abutment groove 2421 and abuts against the abutment groove 2421 under the pulling force of the lifting rope 243. Therefore, there is no need to use a locking member to lock the lifting rope 243 and the mounting block 242, which is convenient to operate and reliable in connection. The second driving assembly is installed in the body 10 and may include a motor (the motor is different from the motor as the first driving member 221) and a roller, and the other end of the lifting rope 243 is wound around the roller, and the motor drives the roller to rotate to reel the lifting rope 243. When the lifting rope 243 is being rolled up, since the fixed block is abutting against the abutting groove 2421, the mounting bracket 24 can be pulled to rotate in a direction away from the surface to be cleaned, so that the cleaning member 21 is separated from the surface to be cleaned. When the surface to be cleaned is a floor that is not suitable for cleaning by the cleaning member 21 (such as a carpet), the cleaning member 21 is prevented from contacting the carpet and causing contamination to the carpet.

[0182] The second embodiment of the present utility model provides a control method for a cleaning device. The method is applied to a cleaning device as an example for explanation. The structure of the cleaning device is specifically provided in the first embodiment of the present utility model. The present utility model embodiment will not be described in detail here. Fig.33 , the control method provided in this embodiment includes the following steps:

[0183] 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.

[0184] Step S12: In response to the second signal when the cleaning member 21 reaches one of the first position and the second position, the motor is controlled to stop rotating, and when the motor is started again, the motor is controlled to rotate in a direction opposite to the last rotation direction to drive the cleaning member 21 to move to the other of the first position and the second position.

[0185] Therefore, in this embodiment, the motor of the first driving assembly 22 can be controlled to rotate to drive the connecting bracket 23 to drive the cleaning member 21 to switch between the first position and the second position, thereby improving the cleaning coverage of the cleaning member 21 on the surface to be cleaned.

[0186] The second signal in this embodiment includes the current value generated by the motor. Then in step S12, the step of controlling the motor to stop rotating may specifically include: judging whether the current value is greater than a predetermined value, and if so, controlling the motor to stop rotating. For example, when the first stopper 251 of the cleaning device abuts against the second stopper 252, the motor will generate a large current due to the occurrence of a stall phenomenon. At this time, in order to avoid the energy consumption caused by the motor stalling to the cleaning device, and to avoid the motor from being stalled for a long time and reducing performance or even being damaged, the present embodiment can detect the current value generated by the motor, and when the current value of the motor is greater than a predetermined value, control the motor to stop running. When the motor is started again, the motor is controlled to rotate in the opposite direction to the last rotation direction (such as the last time the motor was forward, the motor is reversed when it is started again) to drive the cleaning member 21 to move in the opposite direction to the first position or the second position, and the control method is reliable and timely.

[0187] The second signal in this embodiment may also include a trigger signal that the first limit switch 253 or the second limit switch 254 is triggered by the second transmission member 223 of the first drive assembly 22. Then in step S12, the step of controlling the motor to stop rotating may also include: controlling the motor to stop rotating in response to the received trigger signal. That is to say, this embodiment can control the motor to stop running by receiving a trigger signal that the first limit switch 253 or the second limit switch 254 is triggered, so that the cleaning member 21 can stay in the first position or the second position stably and reliably. Moreover, this embodiment can control the motor to stop running by detecting the change in motor current in combination with the received trigger signal, which is not only more accurate and reliable, but also can ensure that the cleaning member 21 can always stay in the specified first position or the second position.

[0188] The third embodiment of the present utility model further provides a base station, which includes a cleaning device. For the specific structure of the cleaning device, please refer to the content provided in the first embodiment of the present utility model, and the present utility model embodiment will not be repeated here.

[0189] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below".
