[0040] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of a cleaning robot provided in an embodiment of the present application, Figure 2 It is a structural schematic diagram of a rotating device provided in an embodiment of the present application.

[0041] The rotating device 100 proposed in the present application is applied to a cleaning robot 1000, which includes a main body 200, a driving mechanism, a pumping mechanism, and a buoyancy mechanism. The driving mechanism is mainly used to drive the main body 200 to move underwater, the pumping mechanism is mainly used to suck garbage during underwater cleaning and to use the recoil force generated by the water pump outlet to fit the bottom wall or side wall of the water bottom, and the buoyancy mechanism is mainly used to provide buoyancy to the main body 200 during surface cleaning, so that the cleaning robot 1000 floats on the water surface.

[0042] It should be noted that the rotating device 100 proposed in the present application can be a roller brush arranged at the front and rear ends of the main body 200, or a driving paddle arranged at the rear end of the main body 200, and both can be detachably installed with the main body 200 using the solution proposed in the present application. The main function of the driving paddle is to drive the main body 200 to move on the water surface, and the main function of the roller brush is to brush the garbage on the bottom wall or side wall of the water when cleaning underwater, and to move the garbage on the water surface and / or accelerate the water flow toward the garbage outlet when cleaning on the water surface.

[0043] In some embodiments, the rotating device 100 proposed in the present application includes a first rotating member 10, a second rotating member 20 and a fixed assembly 30, and the first rotating member 10 and the second rotating member 20 are arranged at intervals along the axis direction of the first rotating member 10 and the second rotating member 20. The first rotating member 10 and the second rotating member 20 are arranged at intervals, which means that when the rotating device 100 proposed in the present application is installed on the main body 200 of the cleaning robot, the preset spacing between the first rotating member 10 and the second rotating member 20, that is, the first state of the rotating device 100 proposed in the present application. When the rotating device 100 is disassembled from the main body 200 of the cleaning robot 1000, the user applies an external force on the first rotating member 10 and / or the second rotating member 20 to move at least one of the first rotating member 10 and the second rotating member 20 along the center of the fixed assembly 30. In this process, the distance between the first rotating member 10 and the second rotating member 20 gradually decreases until the first rotating member 10 and / or the second rotating member 20 are disconnected from the main body 200 of the cleaning robot 1000, that is, the second state of the rotating device 100 proposed in the present application.

[0044] Optionally, at least one of the first rotating member 10 and the second rotating member 20 can slide relative to the fixed assembly 30, that is, the first rotating member 10 and / or the second rotating member 20 can slide axially relative to the fixed assembly 30. Specifically, the first rotating member 10 can move relative to the fixed assembly 30 in a direction close to the center of the fixed assembly 30 under the action of an external force, or the second rotating member 20 can move relative to the fixed assembly 30 in a direction close to the center of the fixed assembly 30 under the action of an external force, or both the first rotating member 10 and the second rotating member 20 can move relative to the fixed assembly 30 in a direction close to the center of the fixed assembly 30 under the action of an external force, and the present application does not limit this.

[0045] In this embodiment, the rotating device 100 has a first state and a second state. The axial length of the rotating device 100 in the first state is greater than the axial length of the rotating device 100 in the second state. In other words, the distance between the first rotating member 10 and the second rotating member 20 when the rotating device 100 is in the first state is greater than the distance between the first rotating member 10 and the second rotating member 20 when the rotating device 100 is in the second state. When the rotating device 100 is in the first state, the axial length of the rotating device 100 is small, which is convenient for removing the rotating device 100 from the housing 201 of the cleaning robot 1000. When the rotating device 100 is in the second state, the axial length of the rotating device 100 is large, which is convenient for engaging the two ends of the rotating device 100 with the housing 201 of the cleaning robot 1000, thereby achieving the fixing of the rotating device 100.

[0046] It should be noted that the first rotating member 10 and the second rotating member 20 may also move in a direction away from the center of the fixing assembly 30 , so that the rotating device 100 changes from the second state to the first state.

[0047] The rotating device 100 of the cleaning robot 1000 proposed in the present application includes a first rotating member 10 and a second rotating member 20 which are separately arranged, and a fixing assembly 30 for connecting the first rotating member 10 and the second rotating member 20. At least one of the first rotating member 10 and the second rotating member 20 can move along the central direction of the fixing assembly 30 under the action of an external force to shorten the axial length of the rotating device 100 as a whole, so that it can be removed from the cleaning robot 1000. In this way, when the rotating device 100 fails, it can be conveniently removed and replaced.

[0048] It should be noted that, in the first state, the axial length of the rotating device 100 is adapted to the cleaning robot 1000, that is, the first axial length when the rotating device 100 is installed on the cleaning robot 1000. In the second state, the axial length of the rotating device 100 is the second axial length, and the second axial length can at least disconnect the first rotating member 10 or the second rotating member 20 from the cleaning robot 1000, that is, the second axial length is a variable length, which can change according to the magnitude of the external force. Of course, the second axial length has a minimum value, which corresponds to the second axial length in the contact state between the first rotating member 10 and the second rotating member 20.

[0049] Please refer to Figure 2 In one embodiment, a first elastic member 40 is provided in the first accommodating cavity of the first rotating member 10, one end of the first elastic member 40 abuts against the fixed component 30, and the other end abuts against the first rotating member 10; and / or, a second elastic member 50 is provided in the second accommodating cavity of the second rotating member 20, one end of the second elastic member 50 abuts against the fixed component 30, and the other end abuts against the second rotating member 20.

[0050] Specifically, a first elastic member 40 is provided in the first accommodating cavity of the first rotating member 10, or a second elastic member 50 is provided in the second accommodating cavity of the second rotating member 20, or a first elastic member 40 is provided in the first accommodating cavity of the first rotating member 10 and a second elastic member 50 is provided in the second accommodating cavity of the second rotating member 20.

[0051] One end of the first elastic member 40 abuts against the fixed assembly 30, and the other end abuts against the first rotating member 10. When the first rotating member 10 moves in a direction close to the center of the fixed assembly 30 under the action of an external force, the first elastic member 40 is compressed, so that the rotating device 100 changes from the first state to the second state, and the first rotating member 10 can be separated from the housing 201 of the cleaning robot 1000. Further, after no external force is applied to the first rotating member 10, the first elastic member 40 in the compressed state will recover its deformation, thereby pushing the first rotating member 10 to move in a direction away from the center of the fixed assembly 30, so that the rotating device 100 changes from the second state to the first state.

[0052] Similarly, one end of the second elastic member 50 abuts against the fixed assembly 30, and the other end abuts against the second rotating member 20. When the second rotating member 20 moves in a direction close to the center of the fixed assembly 30 under the action of an external force, the second elastic member 50 is compressed, so that the rotating device 100 changes from the first state to the second state, and the second rotating member 20 can be separated from the housing 201 of the cleaning robot 1000. Further, after no external force is applied to the second rotating member 20, the second elastic member 50 in the compressed state will recover its deformation, thereby pushing the second rotating member 20 to move in a direction away from the center of the fixed assembly 30, so that the rotating device 100 changes from the second state to the first state.

[0053] Specifically, in the present embodiment, the first elastic member 40 and the second elastic member 50 are both springs. In other embodiments, the first elastic member 40 and the second elastic member 50 may also be spring plates or other elastic structures. The following description of the present application takes the first elastic member 40 and the second elastic member 50 as springs as an example, which should not be construed as a limitation to the present application.

Specifically, the first rotating member 10 can be slidably mounted on the fixing shaft 31, so that the first rotating member 10 can move along the axial direction of the fixing shaft 31, or the second rotating member 20 can be slidably mounted on the fixing shaft 31, so that the second rotating member 20 can move along the axial direction of the fixing shaft 31, or both the first rotating member 10 and the second rotating member 20 can be slidably mounted on the fixing shaft 31, so that both the first rotating member 10 and the second rotating member 20 can move along the axial direction of the fixing shaft 31, and the present application does not limit this.
