[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] After long-term research, the inventors have found that the cleaning device can be provided with a side brush. In the current technology, the side brush may cause some problems when used in some application scenarios, which limits the application scenarios of the cleaning device. For example, when the side brush is cleaning an area with liquid, the liquid on the side brush will contaminate the area to be cleaned, thereby affecting the cleaning effect. For another example, the side brush is easily caught by the wires on the ground. In order to solve this technical problem, the present application provides the following embodiments.

[0018] like Figure 1As shown, the cleaning device 1 can have one or more functions such as sweeping the floor, mopping the floor, scrubbing the floor, and vacuuming. For example, the cleaning device 1 can be a floor sweeping robot, a mopping robot, a mopping and scrubbing integrated robot, a sweeping, washing, and mopping integrated robot, a vacuum cleaner, etc. When the cleaning device 1 performs cleaning work, the cleaning device 1 can absorb various garbage objects from the outside, such as dust particles, paper scraps, hair, etc.

[0019] As Figures 1 to 4 As shown, the cleaning device 1 described in the embodiment of the cleaning device 1 of the present application includes a device main body 100 and a cleaning module 200. The cleaning module 200 is disposed on the device main body 100. The cleaning module 200 includes a cleaning member 210 and a driving component 240 that are drivingly connected. The cleaning member 210 includes a mounting portion 211 and a cleaning portion 213 that are connected to each other, and the cleaning portion 213 is used to clean the area to be cleaned. The driving component 240 is configured to drive the cleaning member 210 to move and deform, so that the cleaning portion 213 rises relative to the mounting portion 211 and the device main body 100.

[0020] By moving and rising relative to the device main body 100, the cleaning portion 213 can be spaced apart from the area to be cleaned (such as the ground), so as to reduce the adverse effects of the environmental factors of the area to be cleaned on the cleaning process. For example, it can reduce the risk that the liquid in the area to be cleaned contaminates the cleaning portion 213 and then damages the cleaning effect, and can also reduce the risk that the wires in the area to be cleaned entangle the side brush and jam the side brush, thereby enriching the application scenarios of the cleaning device 1. In addition, by driving the cleaning member 210 to deform, the cleaning portion 213 can be lifted by a large amplitude, which is beneficial to reducing the moving space of the cleaning member 210 in the height direction D0 of the cleaning device 1, and thus beneficial to reducing the height dimension of the cleaning device 1.

[0021] As Figures 1 to 4 As shown, the cleaning member 210 includes a transmission portion 212, and the transmission portion 212 is connected between the mounting portion 211 and the cleaning portion 213. The cleaning module 200 includes a limiting member 220 and a lifting member 230. The limiting member 220 is configured to limit the mounting portion 211 from rising relative to the device main body 100. The driving component 240 is drivingly connected to the transmission portion 212 through the lifting member 230, and the driving component 240 drives the transmission portion 212 to move upward through the lifting member 230, so as to drive the cleaning portion 213 to rise relative to the device main body 100.

[0022] Specifically, the lifting member 230 is respectively drivingly connected to the driving component 240 and the cleaning member 210. The limiting member 220 is used to limit the mounting portion 211 from rising relative to the device main body 100. The driving component 240 drives the cleaning member 210 to move and deform through the lifting member 230, so that the cleaning portion 213 rises relative to the device main body 100.

[0023] A walking assembly 101 is provided at the bottom of the device body 100. The walking assembly 101 can make the cleaning device 1 movable, so that the cleaning device 1 can walk in the area to be cleaned, driving the cleaning member 210 to clean everywhere in the area to be cleaned. In some embodiments, the walking assembly 101 may include a driving wheel and a universal wheel, and the device body 100 is driven by the driving wheel to walk.

[0024] The cleaning part 213 can contact the area to be cleaned and move relative to the area to be cleaned, so that the area to be cleaned can be cleaned. In some embodiments, the cleaning part 213 is a bristle, and the bristle can contact the area to be cleaned and move relative to the area to be cleaned, so that the area to be cleaned can be cleaned.

[0025] In some embodiments, the cleaning member 210 may be a side brush. The side brush may be disposed at the bottom edge of the cleaning device 1, and part of the bristles of the side brush may protrude from the device body 100 perpendicular to the height direction D0 of the cleaning device 1, so as to facilitate cleaning the edge corner area (e.g., the ground wall) of the area to be cleaned.

[0026] Under the driving action of the driving assembly 240, the lifting member 230 can drive the cleaning part 213 to move upward relative to the device body 100. At the same time, due to the limitation of the limiting member 220, the mounting part 211 may not rise relative to the device body 100. Therefore, the cleaning part 213 moves upward relative to the mounting part 211, causing the cleaning member 210 to deform. In some application scenarios, by moving upward relative to the device body 100, the cleaning part 213 can maintain a distance from the area to be cleaned (such as the ground), thereby reducing the adverse effects of environmental factors in the area to be cleaned on the cleaning process. For example, it can reduce the risk of liquid in the area to be cleaned contaminating the cleaning part 213 and thus destroying the cleaning effect, and it can also reduce the risk of wires in the area to be cleaned being entangled with the side brush and getting stuck on the side brush, thereby enriching the application scenarios of the cleaning device 1.

[0027] The first end of the cleaning portion 213 close to the mounting portion 211 can be used to connect with the mounting portion 211, and the second end of the cleaning portion 213 facing away from the mounting portion 211 can contact the area to be cleaned. The cleaning portion 213 rises relative to the device body 100 under the drive of the lifting member 230, while the mounting portion 211 may not rise. Restricted by the mounting portion 211, the rising amplitude of the first end of the cleaning portion 213 may be smaller than that of the second end of the cleaning portion 213. In other words, by utilizing the principle of leverage, the first end of the cleaning portion 213 can rise by a smaller amplitude so that the second end of the cleaning portion 213 can rise by a larger amplitude, which is conducive to reducing the movable space of the lifting member 230 and the first end of the cleaning portion 213 close to the mounting portion 211 in the height direction D0 of the cleaning device 1, thereby helping to reduce the height dimension of the cleaning device 1.

[0028] In some embodiments, along the height direction D0 of the cleaning device 1, the limiting member 220 abuts against the upper side of the mounting portion 211, so as to be able to limit the upward movement of the mounting portion 211.

[0029] In some embodiments, along the height direction D0 of the cleaning device 1, the limiting member 220 is relatively fixed to the device main body 100. In other embodiments, the limiting member 220 is arranged to be able to move up and down relative to the device main body 100.

[0030] In other embodiments, the cleaning module 200 includes a limiting member 220 and a lifting member 230. The limiting member 220 is arranged to limit the downward movement of the transmission portion 212 relative to the device main body 100. The driving assembly 240 drives the mounting portion 211 to move downward through the lifting member 230, so that the cleaning member 210 moves and deforms, and further the cleaning portion 213 rises relative to the device main body 100.

[0031] When the mounting portion 211 moves downward, the transmission portion 212 can serve as the fulcrum of the lever. In this way, the cleaning portion 213 can rise relative to the device main body 100. Further, through the lever principle, the end of the cleaning portion 213 far from the mounting portion 211 can rise by a relatively large amplitude, which is beneficial to reducing the moving space of the cleaning member 210 in the height direction D0 of the cleaning device 1, and thus is beneficial to reducing the height dimension of the cleaning device 1.

[0032] Optionally, as Figures 1 to 4 shown, the cleaning module 200 includes a bracket assembly 260. The cleaning module 200 is connected to the device main body 100 through the bracket assembly 260. The cleaning member 210, the limiting member 220, the lifting member 230 and the driving assembly 240 can be arranged on the bracket assembly 260.

[0033] Optionally, as Figures 1 to 4 shown, the cleaning member 210 includes a transmission portion 212. The transmission portion 212 is connected between the mounting portion 211 and the cleaning portion 213. The lifting member 230 abuts against the transmission portion 212. Along the height direction D0 of the cleaning device 1, the driving assembly 240 drives the lifting member 230 to move upward, so as to drive the transmission portion 212 to move upward, so that the transmission portion 212 drives the cleaning portion 213 to rise relative to the device main body 100.

[0034] By abutting against the transmission part 212, the lifting member 230 can realize the transmission effect on the cleaning part 213. The first end of the cleaning part 213 close to the mounting part 211 can be connected to the mounting part 211 through the transmission part 212, and the second end of the cleaning part 213 away from the mounting part 211 can contact the area to be cleaned. Driven by the lifting member 230, the transmission part 212 and the cleaning part 213 rise relative to the device body 100, while the mounting part 211 may not rise. Restricted by the mounting part 211, the rising amplitude of the transmission part 212 may be smaller than the first end of the cleaning part 213 close to the mounting part 211, and the rising amplitude of the first end of the cleaning part 213 close to the mounting part 211 may be smaller than the second end of the cleaning part 213.

[0035] By utilizing the lever principle, the mounting portion 211 can be used as a fulcrum for the cleaning portion 213 to rise, and the transmission portion 212 extends the distance between the second end of the cleaning portion 213 and the mounting portion 211. The lifting member 230 drives the transmission portion 212 to rise by a small amount, so that the second end of the cleaning portion 213 can rise by a large amount, which is beneficial to further reduce the activity space of the lifting member 230 and the first end of the cleaning portion 213 in the height direction D0 of the cleaning device 1, thereby helping to reduce the height dimension of the cleaning device 1.

[0036] For example, along the height direction D0 of the cleaning device 1 , the lifting member 230 moves upward by 3 mm to 5 mm, which can drive the second end of the cleaning portion 213 to move upward by 15 mm to 25 mm.

[0037] In some embodiments, the cleaning member 210 is a sweeping brush, the cleaning portion 213 is bristles, and the transmission portion 212 is plastic that wraps the bristles near the mounting portion 211. The transmission portion 212 can both connect the bristles and the mounting portion 211 and fix the bristles into a bundle.

[0038] In some embodiments, along the height direction D0 of the cleaning device 1 , the lifting member 230 abuts against the lower side of the transmission part 212 , and when the lifting member 230 moves upward, it drives the transmission part 212 to rise through the supporting effect.

[0039] In some embodiments, along the height direction D0 of the cleaning device 1 , the lifting member 230 is configured to slide upward relative to the limiting member 220 . In other embodiments, the lifting member 230 is configured to rotate upward relative to the limiting member 220 .

[0040] Alternatively, if Figures 1 to 4 As shown, the transmission part 212 and the mounting part 211 are elastically connected, and the driving assembly 240 drives the cleaning member 210 to move and elastically deform through the lifting member 230. The cleaning member 210 allows the transmission part 212 to drive the cleaning member 213 to rise relative to the device body 100 through elastic deformation, and the cleaning member 210 recovers through elastic deformation so that the transmission part 212 drives the cleaning member 213 to reset.

[0041] Specifically, when the driving component 240 drives the lifting member 230 to move upward, and the cleaning portion 213 and the transmission portion 212 move upward relative to the mounting portion 211, the cleaning member 210 undergoes elastic deformation. When the lifting member 230 moves downward under the drive of the driving component 240 or under the action of other forces, the elastic deformation of the cleaning member 210 is restored, driving the cleaning portion 213 and the transmission portion 212 to move downward relative to the mounting portion 211, so that the cleaning portion 213 is reset. After the cleaning portion 213 is reset, it can abut against the area to be cleaned. In this way, it is beneficial for the cleaning portion 213 to be quickly and timely reset. In addition, when the ground is uneven, the cleaning member 210 can make the cleaning portion 213 float up and down with the undulation of the ground through elastic deformation, so as to improve the cleaning effect.

[0042] Furthermore, the transmission portion 212 itself and the cleaning portion 213 itself can both undergo elastic deformation to better adapt to the undulation of the ground.

[0043] Optionally, as Figure 4 shown, the number of the transmission portions 212 is at least two, and the at least two transmission portions 212 are arranged at intervals along the circumferential direction D3 of the mounting portion 211. The transmission portion 212 and the mounting portion 211 are elastically connected by an integral molding method. For example, the number of the transmission portions 212 is 3, and the cleaning portion 213 and the transmission portions 212 can be connected in one-to-one correspondence.

[0044] For example, both the transmission portion 212 and the mounting portion 211 are made of elastic polymer materials, such as both the transmission portion 212 and the mounting portion 211 are made of plastic, silica gel or rubber materials.

[0045] Such a setting is beneficial to simplify the assembly process, improve the assembly efficiency, and at the same time is beneficial to improve the connection stability between the transmission portion 212 and the mounting portion 211.

[0046] In some other embodiments, the transmission portion 212 and the mounting portion 211 are elastically connected through elastic parts. For example, the transmission portion 212 and the mounting portion 211 are elastically connected through elastic parts made of polymer materials or springs.

[0047] Optionally, as Figures 1 to 4 shown, a receiving space 232 is formed between the limiting member 220 and the lifting member 230, and the mounting portion 211 is arranged in the receiving space 232. In some embodiments, the lifting member 230 is provided with a mounting opening 233. In some other embodiments, the limiting member 220 is provided with a mounting opening 233, or a mounting opening 233 is formed between the lifting member 230 and the limiting member 220. The receiving space 232 communicates with the outside through the mounting opening 233, and the transmission portion 212 passes through the mounting opening 233.

[0048] By disposing the installation part 211 within the accommodation space 232, it is conducive to enhancing the stability of the assembly relationship between the installation part 211, the limiting part 220, and the lifting part 230. Among them, the position of the installation opening 233 can be determined according to the shape and attitude of the transmission part 212. For example, in some embodiments, the limiting part 220 is disposed above the lifting part 230, and the transmission part 212 extends obliquely downward from the installation part 211 to the outside, then the lifting part 230 is provided with the installation opening 233. In other embodiments, the transmission part 212 extends horizontally from the installation part 211 to the outside, then the limiting part 220 is provided with the installation opening 233, or an installation opening 233 is formed between the lifting part 230 and the limiting part 220.

[0049] In some embodiments, as Figures 1 to 4 shown, the lifting part 230 has a columnar protrusion 231 protruding towards the limiting part 220, and the installation part 211 is sleeved on the columnar protrusion 231 to enhance the stability of the assembly relationship between the installation part 211, the limiting part 220, and the lifting part 230.

[0050] In some embodiments, the lifting part 230 is provided with the installation opening 233, and the transmission part 212 passes through the installation opening 233. When the lifting part 230 rotates around the following preset axis, the cleaning part 210 can be driven to rotate around the following preset axis through the transmission part 212.

[0051] Optionally, as Figure 1 , Figure 3 and Figure 5 shown, the cleaning device 1 further includes an elastic member 250. In some embodiments, as Figure 1 and Figure 3 shown, along the height direction D0 of the cleaning device 1, the elastic member 250 elastically abuts between the lifting part 230 and the limiting part 220. In other embodiments, as Figure 1 and Figure 5 shown, along the height direction D0 of the cleaning device 1, the elastic member 250 elastically abuts between the lifting part 230 and the installation part 211. When the lifting part 230 moves upward, the elastic member 250 elastically deforms, and when the lifting part 230 moves downward, the elastic member 250 elastically deforms and recovers.

[0052] For example, the elastic member 250 is a spring or a spring sheet.

[0053] Specifically, when the driving assembly 240 drives the lifting part 230 to move upward and drives the cleaning part 213 to rise, the elastic member 250 is compressed and deformed. When the lifting part 230 moves downward and the cleaning part 213 descends, the elastic member 250 recovers from the compressed deformation, which can promote the accurate reset of the lifting part 230. On the other hand, the recovery of the elastic deformation of the elastic member 250 can promote the deformation recovery of the cleaning member 210, which is beneficial for the cleaning part 213 to descend to a reasonable position.

[0054] Optionally, as Figure 1 , Figure 3 and Figure 5 shown, the cleaning member 210 is rotatably connected to the device main body 100 by at least one of the limiting member 220 and the lifting member 230. The driving assembly 240 is configured to drive at least one of the lifting member 230 and the limiting member 220 to rotate relative to the device main body 100 about a preset axis, so as to drive the cleaning member 210 to rotate about the preset axis. Wherein, the preset axis is the rotation axis of the cleaning member 210.

[0055] When the cleaning member 210 contacts the area to be cleaned, it can rotate about the preset axis to clean the area to be cleaned. The driving assembly 240 is used to drive the cleaning member 210 to rotate and also to drive the cleaning part 213 to rise. In this way, it is beneficial to simplify the structure of the cleaning module 200 and reduce the number of motors provided.

[0056] In some embodiments, the cleaning member 210 is connected to the lifting member 230, and the lifting member 230 is rotatably connected to the device main body 100. The driving assembly 240 is configured to drive the lifting member 230 to rotate relative to the device main body 100 about a preset axis, so as to drive the cleaning member 210 to rotate about the preset axis. The driving assembly 240 drives the cleaning member 210 to rotate and drives the cleaning part 213 to rise through the lifting member 230. In this way, it is beneficial to further simplify the structure of the cleaning module 200.

[0057] In some embodiments, the cleaning member 210 is connected to at least one of the limiting member 220 and the lifting member 230 through the mounting portion 211.

[0058] In some embodiments, the cleaning member 210 is connected to the lifting member 230 through the transmission portion 212.

[0059] In some embodiments, the cleaning member 210 is simultaneously connected to the lifting member 230 and the limiting member 220, and both the lifting member 230 and the limiting member 220 are rotatably connected to the device main body 100. The driving assembly 240 is configured to drive the lifting member 230 and the limiting member 220 to rotate relative to the device main body 100 about a preset axis, so as to drive the cleaning member 210 to rotate about the preset axis.

[0060] In some other embodiments, the cleaning member 210 is connected to the limiting member 220, and the limiting member 220 is rotatably connected to the device main body 100. The driving assembly 240 is configured to drive the limiting member 220 to rotate relative to the device main body 100 about a preset axis, so as to drive the cleaning member 210 to rotate about the preset axis.

[0061] Optionally, as Figures 1 to 3As shown, the driving assembly 240 includes a first transmission mechanism 241, a rotating motor 242, and a lifting motor (not shown in the figure). The output shafts of the rotating motor 242 and the lifting motor are both drivingly connected to the cleaning member 210 through the first transmission mechanism 241. The lifting motor is used to drive the cleaning part 213 to rise relative to the device main body 100 through the first transmission mechanism 241. The rotating motor 242 is used to drive the cleaning member 210 to rotate around a preset axis through the first transmission mechanism 241.

[0062] Specifically, the first transmission mechanism 241 is drivingly connected to the cleaning member 210 through the lifting member 230. The output shafts of the rotating motor 242 and the lifting motor are both drivingly connected to the cleaning member 210 through the first transmission mechanism 241 and the lifting member 230. By setting the rotating motor 242 and the lifting motor to drive the cleaning member 210 respectively, it is beneficial to reduce the mutual interference between different actions of the cleaning member 210.

[0063] Optionally, as Figures 1 to 3 shown, the first transmission mechanism 241 includes a first transmission member 2411 and a second transmission member 2412 that are rotatably connected. The second transmission member 2412 is drivingly connected to the cleaning member 210. The output shaft of the lifting motor is drivingly connected to the first transmission member 2411, and the output shaft of the rotating motor 242 is drivingly connected to the second transmission member 2412. Along the height direction D0 of the cleaning device 1, the first transmission member 2411 is used to move upward under the drive of the lifting motor, so as to drive the cleaning part 213 to move upward through the second transmission member 2412. The second transmission member 2412 is used to rotate under the drive of the rotating motor 242, so as to drive the cleaning member 210 to rotate around a preset axis.

[0064] Specifically, the second transmission member 2412 is drivingly connected to the cleaning member 210 through the lifting member 230. Along the height direction D0 of the cleaning device 1, the first transmission member 2411 drives the lifting member 230 to move upward through the second transmission member 2412, and then drives the cleaning part 213 to move upward. The second transmission member 2412 drives the lifting member 230 to rotate around a preset axis, and then drives the cleaning member 210 to rotate around a preset axis.

[0065] Optionally, as Figures 1 to 3 shown, the first transmission mechanism 241 includes a gear set. The second transmission member 2412 is drivingly connected to the rotating motor 242 through the gear set. Further, the gear set includes a first final gear 2413. The first final gear 2413 has a hole with a non-circular cross-section (such as a circular segment shape). The second transmission member 2412 passes through the hole of the first final gear 2413 and matches the shape of the hole of the first final gear 2413, so that the first final gear 2413 can drive the second transmission member 2412 to rotate and allow the second transmission member 2412 to slide and lift along the extension direction of the hole.

[0066] In some embodiments, the limiting member 220 is fixedly arranged with the first final-stage gear 2413, or the limiting member 220 is integrally formed and connected with the first final-stage gear 2413.

[0067] In some embodiments, such as Figures 1 to 3 shown, the second transmission member 2412 is provided with a first snap ring 2414. When the second transmission member 2412 descends to the target position, the first snap ring 2414 can abut against other structures to limit the further descent of the second transmission member 2412.

[0068] By arranging the first transmission member 2411 and the second transmission member 2412 to be rotatably connected, when the second transmission member 2412 rotates driven by the rotating motor 242, the first transmission member 2411 can remain stationary, which is beneficial to improving the connection stability between the first transmission member 2411 and the lifting motor. For example, the second transmission member 2412 rotates relative to the first transmission member 2411 through a rolling bearing 2415.

[0069] Optionally, the second transmission member 2412 and the cleaning member 210 are coaxially arranged and both rotate relative to the device main body 100 around a preset axis.

[0070] Optionally, the first transmission member 2411 is arranged above the second transmission member 2412.

[0071] Optionally, as Figure 1 , Figures 5 to 8 shown, the drive assembly 240 includes a second transmission mechanism 244 and a drive motor 245. The output shaft of the drive motor 245 is in transmission connection with the cleaning member 210. The drive motor 245 is used to drive the cleaning part 213 to rise relative to the device main body 100 through the second transmission mechanism 244, and is also used to drive the cleaning member 210 to rotate around a preset axis through the second transmission mechanism 244.

[0072] Specifically, the second transmission mechanism 244 is in transmission connection with the cleaning member 210 through a lifting member 230. The drive motor 245 is used to drive the cleaning part 213 to rise relative to the device main body 100 and drive the cleaning member 210 to rotate around a preset axis through the second transmission mechanism 244 and the lifting member 230. The drive assembly 240 is used to drive the cleaning member 210 to rotate and is also used to drive the cleaning part 213 to rise. In this way, it is beneficial to reduce the number of motors provided.

[0073] Optionally, as Figure 1 , Figures 5 to 8As shown, the second transmission mechanism 244 includes a main transmission member 246, a driven transmission member 247, and a stop member 248. The main transmission member 246 is respectively in transmission connection with the cleaning member 210 and the drive motor 245. The drive motor 245 drives the cleaning member 210 to rotate through the main transmission member 246. The main transmission member 246 is also in threaded connection with the driven transmission member 247. The stop member 248 is connected to the driven transmission member 247, and the stop member 248 is arranged to allow the driven transmission member 247 to rotate along a preset first direction D1 and restrict the driven transmission member 247 from rotating along a preset second direction D2 opposite to the preset first direction D1. The drive motor 245 drives the cleaning portion 213 to rise relative to the device main body 100 through the main transmission member 246 and the driven transmission member 247.

[0074] The central axis of the thread can be collinear with the preset axis and parallel to the height direction D0 of the cleaning device 1. Under the drive of the drive motor 245 or under the action of other forces, the main transmission member 246 and the driven transmission member 247 can move relative to each other along the extension direction of the thread, that is, the main transmission member 246 and the driven transmission member 247 can rotate relative to each other and move relative to each other along the central axis direction of the thread.

[0075] Specifically, when the cleaning member 210 is in the lowered position, the forward rotation of the drive motor 245 can drive the main transmission member 246 and the driven transmission member 247 to rotate together along the preset first direction D1, and then drive the cleaning member 210 to rotate along the preset first direction D1 to clean the area to be cleaned.

[0076] When the cleaning member 210 is in the lowered position, the reverse rotation of the drive motor 245 can drive the main transmission member 246 to rotate along the preset second direction D2. Under the restrictive action of the stop member 248 on the driven transmission member 247, the main transmission member 246 and the driven transmission member 247 can rotate relative to each other, so that the main transmission member 246 moves upward to drive the lifting member 230 to rise, and then the cleaning portion 213 rises relative to the device main body 100.

[0077] When the cleaning member 210 is in the raised position, the forward rotation of the drive motor 245 can drive the main transmission member 246 and the driven transmission member 247 to rotate together along the preset first direction D1. At the same time, under the action of the gravity of the cleaning member 210 and the main transmission member 246, there is a difference in the rotation speed of the main transmission member 246 and the driven transmission member 247 along the preset first direction D1. The main transmission member 246 and the driven transmission member 247 rotate relative to each other, so that the main transmission member 246 moves downward, and the lifting member 230 and the cleaning portion 213 can descend relative to the device main body 100. In some embodiments, the elastic deformation recovery of the cleaning member 210 and the elastic deformation recovery of the elastic member 250 can also promote the descent of the lifting member 230.

[0078] When the main transmission member 246 is driven by the driving motor 245 to rotate, it can drive the lifting member 230 to rotate around a preset axis, and further drive the cleaning member 210 to rotate around the preset axis.

[0079] With such arrangement, the driving motor 245 can drive the cleaning portion 213 to rotate and ascend around a preset axis, so that the cleaning device 1 has a variety of cleaning actions to meet the diverse cleaning needs of different areas, while simplifying the structure of the cleaning module 200 .

[0080] Optionally, the stopper 248 is a one-way bearing, for example, the one-way bearing includes a fixed bracket and a ball or a needle.

[0081] Alternatively, if Figures 5 to 8 As shown, the slave transmission member 247 is provided with an internal thread 2471 . The main transmission member 246 is provided with an external thread 2461 that matches the internal thread 2471 , so as to be threadedly connected with the slave transmission member 247 .

[0082] Such an arrangement facilitates the transmission connection between the main transmission member 246 and the drive motor 245 .

[0083] In other embodiments, the slave transmission member 247 is provided with an external thread 2461 . The main transmission member 246 is provided with an internal thread 2471 matching with the external thread 2461 to be threadedly connected with the slave transmission member 247 .

[0084] Alternatively, if Figures 5 to 8 As shown, the second transmission mechanism 244 includes a gear set. The main transmission member 246 is connected to the driving motor 245 through the gear set. Further, the gear set includes a second final gear 2462, and the second final gear 2462 has a hole with a non-circular cross-section (e.g., a circular segment shape). The main transmission member 246 is inserted into the hole of the second final gear 2462 and matches the hole shape of the second final gear 2462, so that the second final gear 2462 can drive the main transmission member 246 to rotate and allow the main transmission member 246 to slide and rise and fall along the extension direction of the hole.

[0085] In some embodiments, the main transmission member 246 is provided with a second retaining spring 2463. When the main transmission member 246 descends to the target position, the second retaining spring 2463 can abut against other structures to limit the main transmission member 246 from continuing to descend.

[0086] Alternatively, if Figures 5 to 8 As shown, the second transmission mechanism 244 includes a connecting flexible shaft 249 , and the main transmission member 246 is transmission-connected to the cleaning member 210 via the connecting flexible shaft 249 .

[0087] By providing a connecting flexible shaft 249, long-distance transmission can be easily achieved, which is beneficial to simplifying the transmission structure of the cleaning device 1 and facilitating assembly. In addition, the connecting flexible shaft 249 has a certain degree of deformation ability and can be bent and twisted to facilitate adjusting the torque direction and position during the transmission process. On the one hand, it is beneficial to reducing the impact on the drive motor 245 caused by the impact force received by the cleaning member 210, playing a shock-absorbing role. On the other hand, when adjusting the position or posture of the cleaning member 210, the output shaft of the drive motor 245 and the cleaning member 210 can still maintain a stable connection, which is beneficial to improving the structural stability and flexibility of the cleaning device 1 and facilitating the adjustment of the position or posture of the cleaning member 210.

[0088] It should be noted that since the connecting flexible shaft 249 can be bent and deformed, after actual assembly, the shape of the connecting flexible shaft 249 may be different from Figures 5 to 9 the shape presented.

[0089] Optionally, as Figure 1 、 Figures 5 to 9 shown, the second transmission mechanism 244 includes a connecting sleeve 2491. The connecting sleeve 2491 is sleeved on the outer periphery of the connecting flexible shaft 249, and the connecting sleeve 2491 is used to guide the extending direction of the connecting flexible shaft 249. For example, the connecting sleeve 2491 can be bent and arranged, and the connecting flexible shaft 249 is bent along with the shape of the connecting sleeve 2491, which is beneficial to reducing the occupied space of the second transmission mechanism 244.

[0090] In this way, the connecting sleeve 2491 can play a role in protecting the connecting flexible shaft 249, and at the same time can allow the connecting flexible shaft 249 to twist and transmit torque.

[0091] In some embodiments, the connecting sleeve 2491 is set to be semi-rigid and semi-flexible. The semi-flexibility enables the connecting sleeve 2491 to also be bent and deformed, and the semi-rigidity enables the connecting sleeve 2491 to have a shaping ability.

[0092] Optionally, the limiting member 220 is connected to the device main body 100 through the connecting sleeve 2491. Along the height direction D0 of the cleaning device 1, the connecting sleeve 2491 is also used to limit the upward movement of the limiting member 220 relative to the device main body 100.

[0093] That is to say, the connecting sleeve 2491 can play a role in supporting the limiting member 220 downward, so that the limiting member 220 can maintain a downward acting force on the mounting portion 211.

[0094] In summary, in this embodiment, by moving upward relative to the device main body 100, the cleaning part 213 can be kept at a distance from the area to be cleaned (such as the ground), so as to reduce the adverse impact of the environmental factors of the area to be cleaned on the cleaning process. For example, it can reduce the risk that the liquid in the area to be cleaned contaminates the cleaning part 213 and then destroys the cleaning effect, and can also reduce the risk that the wires in the area to be cleaned wind around and jam the side brush. Thus, the application scenarios of the cleaning device 1 are enriched. By using the lever principle, a small upward movement of the first end of the cleaning part 213 close to the installation part 211 can cause a large upward movement of the second end of the cleaning part 213 away from the installation part 211, which is beneficial to reducing the moving space of the lifting part 230 and the first end of the cleaning part 213 close to the installation part 211 in the height direction D0 of the cleaning device 1, and thus beneficial to reducing the height dimension of the cleaning device 1.

[0095] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present application.
