Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0026] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0027] The cleaning component and the cleaning robot provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0028] [[ID=]17]Reference Figures 1-7 , a cleaning component provided in an embodiment of the present application may include a cleaning member and a stopper 400. Among them, the cleaning member may include a cleaning disk 300 and a cleaning tool. The cleaning tool may be disposed on the cleaning disk 300, and the cleaning disk 300 may be used to connect to the motor shaft 200 of the cleaning robot. In this way, the motor shaft 200 of the cleaning robot can drive the cleaning member to rotate for cleaning operations. Here, the cleaning tool may be a rag, a brush, or other tools that can achieve cleaning.

[0029] The stopper 400 can be connected to the side of the cleaning disc 300 facing away from the cleaning tool. The stopper 400 can be provided with a through hole 430 for the motor shaft 200 to pass through, that is, the stopper 400 is sleeved outside the motor shaft 200. In this way, the stopper 400 can protect the motor shaft 200. Wherein, an annular blocking portion 410 can be provided on the outer wall of the stopper 400. The annular blocking portion 410 can be arranged around the stopper 400 and can be arranged near one end of the stopper 400 facing away from the cleaning disc 300. In this way, the annular blocking portion 410 can block foreign matters such as hair, so as to prevent foreign matters such as hair from entering between the stopper 400 and the bottom shell of the cleaning robot and winding around the motor shaft 200, and further can avoid the phenomenon of excessive current or stall of the motor, which is beneficial to extending the service life of the motor.

[0030] In an alternative embodiment of the present application, a winding rib 421 can be provided on the outer wall of the stopper 400. The winding rib 421 can protrude away from the through hole 430. In this way, when the cleaning member performs a cleaning operation, it is convenient for foreign matters such as hair to wind around the stopper 400, and the winding rib 421 can block foreign matters such as hair to prevent the foreign matters from falling off, and further can prevent foreign matters such as hair from entering between the stopper 400 and the bottom shell of the cleaning robot and winding around the motor shaft 200.

[0031] Certainly, in other embodiments, the winding rib 421 may not be provided on the outer wall of the stopper 400.

[0032] In an alternative embodiment, at least two winding portions 420 can be provided on the outer wall of the stopper 400. Each winding portion 420 can be spaced apart along the direction from the cleaning member to the annular blocking portion 410, and each winding portion 420 can include at least two winding ribs 421. Each winding rib 421 can be distributed along the circumferential direction of the stopper 400. In this way, the winding area of foreign matters such as hair can be increased, so that the stopper 400 can wind more foreign matters such as hair, and further the blocking effect of the stopper 400 can be improved.

[0033] Certainly, only one winding rib 421 may also be provided on the outer wall of the stopper 400.

[0034] In an alternative embodiment of the present application, a stopper connecting portion 310 may be provided on the side of the cleaning disk 300 facing away from the cleaning tool. The stopper connecting portion 310 may be provided with a connecting cavity 311, and the stopper 400 may include a cleaning disk connecting portion 402 and a blocking portion 401. The blocking portion 401 may be connected to the cleaning disk connecting portion 402. The cleaning disk connecting portion 402 may be embedded in the connecting cavity 311 and connected to the stopper connecting portion 310. In this way, the connecting area between the stopper 400 and the cleaning disk 300 can be increased, and thus the connecting strength between the stopper 400 and the cleaning disk 300 can be improved. Optionally, the cleaning disk connecting portion 402 may also be connected to the stopper connecting portion 310 through a fixing member, so as to further improve the connecting strength between the stopper 400 and the cleaning disk 300.

[0035] Here, an annular blocking portion 410 may be provided on the blocking portion 401 to be able to block foreign objects such as hair.

[0036] In other embodiments, the stopper connecting portion 310 may not be provided on the side of the cleaning disk 300 facing away from the cleaning tool. Specifically, the stopper 400 may be directly connected to the side of the cleaning disk 300 facing away from the cleaning tool through a fixing member. Here, the fixing member may be a screw. Of course, the cleaning disk 300 and the stopper 400 may also be of an integral structure.

[0037] In an alternative embodiment, a first connecting member 320 may be provided in the connecting cavity 311. The first connecting member 320 may be used to connect to the motor shaft 200. A convex portion 404 may be provided on the cleaning disk connecting portion 402. The convex portion 404 may protrude away from the stopper connecting portion 310, and the convex portion 404 and the first connecting member 320 may be in limit fit in the direction from the cleaning disk 300 to the annular blocking portion 410. In this way, the convex portion 404 can limit the first connecting member 320 to prevent the first connecting member 320 from disengaging from the connecting cavity 311, and thus the connecting stability between the cleaning disk 300 and the motor shaft 200 can be improved. And the first connecting member 320 is fixed by the convex portion 404, which is convenient for later disassembly and replacement of the first connecting member 320.

[0038] Of course, the convex portion 404 may not be provided on the cleaning disk connecting portion 402. Specifically, the first connecting member 320 may be fixedly connected to the stopper connecting portion 310 in a non-detachable manner, or the first connecting member 320 and the stopper connecting portion 310 may be fixedly connected by screws or the like.

[0039] Optionally, a convex platform 314 may be provided in the connecting cavity 311. A receiving cavity may be provided on the convex platform 314. The first connecting member 320 may be located in the receiving cavity, and the convex portion 404 may be located on the side of the receiving cavity facing away from the cleaning disk 300 to be able to limit the first connecting member 320 in the receiving cavity.

[0040] Further optionally, a first through hole 431 may be provided on the blocking portion 401, and a second through hole 432 may be provided on the cleaning disk connecting portion 402. The above-mentioned through hole 430 may include a first through hole 431 and a second through hole 432, and the aperture of the second through hole 432 gradually decreases along the direction from the blocking portion 401 to the cleaning disk connecting portion 402. In this way, the hole wall of the second through hole 432 can play a certain guiding role on the motor shaft 200, so as to facilitate the connection between the first connecting member 320 and the motor shaft 200.

[0041] In an optional embodiment, one of the cleaning tray connecting portion 402 and the cavity wall of the connecting cavity 311 may be provided with an inserting portion 403, and the other may be provided with a slot 313, and the inserting portion 403 may be inserted into the slot 313. In this way, the connection strength between the cleaning tray connecting portion 402 and the blocking member connecting portion 310 can be further improved, and the connection strength between the blocking member 400 and the cleaning tray 300 can be further improved.

[0042] Of course, the plug-in portion 403 and the slot 313 may not be provided on the cleaning disk connecting portion 402 and the cavity wall of the connecting cavity 311 .

[0043] Furthermore, an annular groove 312 can be provided on the stopper connecting portion 310, and the annular groove 312 can be located on the side of the connecting cavity 311 away from the cleaning tool. The end of the blocking portion 401 close to the cleaning disk connecting portion 402 can be embedded in the annular groove 312 and fit with the bottom of the annular groove 312. In this way, the contact area between the stopper 400 and the stopper connecting portion 310 can be further increased, and the connection strength between the stopper 400 and the cleaning disk 300 can be further improved.

[0044] In an optional embodiment of the present application, a first stopper 440 may be provided on the wall of the through hole 430. The first stopper 440 may be configured to cooperate with the circumferential upper limit of the motor shaft 200 in the through hole 430. In this way, relative rotation between the stopper 400 and the motor shaft 200 may be prevented, thereby preventing the motor shaft 200 from being able to drive the cleaning element to rotate.

[0045] In other embodiments, the first limiting member 440 may not be provided on the hole wall of the through hole 430 , and the hole wall of the through hole 430 may be tightly fitted with the motor shaft 200 .

[0046] In an alternative embodiment, the first limiting member 440 may include a guiding portion 441 and a limiting portion 442. The limiting portion 442 may be connected to the guiding portion 441, and the limiting portion 442 may be located on a side of the guiding portion 441 close to the cleaning disk 300. In the direction from the guiding portion 441 to the limiting portion 442, the width of the guiding portion 441 in the circumferential direction of the through hole 430 may gradually increase. In this way, the guiding portion 441 can guide the second limiting member on the motor shaft 200, facilitating the entry of the motor shaft 200 into the connection cavity 311 and the movement of the second limiting member to a side of the first limiting member 440. Furthermore, when the motor shaft 200 enters the through hole 430, alignment operations are not required, facilitating assembly.

[0047] Of course, the first limiting member 440 may also include only the limiting portion 442. When assembling the motor shaft 200 and the cleaning member, the second limiting member on the motor shaft 200 needs to be avoided from the limiting portion 442 first, and then the motor shaft 200 can extend into the through hole 430.

[0048] Based on the cleaning assembly provided by the embodiments of the present application, the embodiments of the present application further provide a cleaning robot. The cleaning robot may include a robot main body 100, a motor shaft 200, and the cleaning assembly described in any of the above embodiments. The motor shaft 200 may be disposed on the robot main body 100, and the cleaning disk 300 of the cleaning assembly may be connected to the motor shaft 200.

[0049] The beneficial effects achieved by the cleaning robot provided by the embodiments of the present application are consistent with those achieved by the cleaning assembly provided by the embodiments of the present application, and will not be elaborated here.

[0050] In an alternative embodiment of the present application, a first connecting member 320 may be disposed on the cleaning disk 300, and a second connecting member 240 may be disposed on the motor shaft 200. The first connecting member 320 and the second connecting member 240 may be magnetically connected. This setting has a simple structure and facilitates the disassembly and assembly of the cleaning member.

[0051] Optionally, one of the first connecting member 320 and the second connecting member 240 may be a magnet, and the other may be an iron sheet. Alternatively, both the first connecting member 320 and the second connecting member 240 may be magnets.

[0052] In other embodiments, the first connecting member 320 and the second connecting member 240 may be snap-connected or connected by screws.

[0053] In an alternative embodiment, a first limiting member 440 may be disposed on the hole wall of the through hole 430, and a second limiting member may be disposed on the outer wall of the motor shaft 200. The first limiting member 440 and the second limiting member may be in circumferential limiting cooperation on the motor shaft 200. In this way, relative rotation between the stopper 400 and the motor shaft 200 can be avoided.

[0054] Here, the second limiting member may be a rib provided on the motor shaft 200, and the length direction of the rib may be parallel to the axial direction of the motor shaft 200.

[0055] In other embodiments, the first limiting member 440 may not be provided on the hole wall of the through hole 430, and the second limiting member may not be provided on the outer wall of the motor shaft 200.

[0056] Optionally, at least two first limiting members 440 may be provided on the hole wall of the through hole 430, and the first limiting members 440 may be spaced apart along the circumferential direction of the through hole 430. At least two second limiting members may be provided on the outer wall of the motor shaft 200, and the second limiting members may be spaced apart along the circumferential direction of the motor shaft 200. Each of the first limiting members 440 is in limiting cooperation with each of the second limiting members in the circumferential direction of the motor shaft 200. In this way, the limiting effect can be improved, and the force balance between the motor shaft 200 and the stopper 400 can be ensured.

[0057] In an alternative embodiment, the motor shaft 200 may include a rotating shaft 210 and a fastening member 220 sleeved outside the rotating shaft 210. The fastening member 220 can slide relative to the rotating shaft 210 along the axial direction of the rotating shaft 210, and the second connecting member 240 may be provided on the fastening member 220. An elastic member 230 may be provided between one end of the fastening member 220 close to the first connecting member 320 and the rotating shaft 210, so that the fastening member 220 can be floatingly arranged on the rotating shaft 210 along the axial direction of the rotating shaft 210. In this way, the cleaning tool can move axially to adapt to floors with different heights.

[0058] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
