[0045] Please refer to Figures 1 to 4, the underwater cleaning robot 100 according to an embodiment of the present invention includes a vehicle body 10, wheels 20 and a rotary brush assembly 30. The vehicle body 10 is the core load-bearing component of the underwater cleaning robot 100. The wheels 20 are connected to the vehicle body 10 and can rotate relative to the vehicle body 10 to drive the underwater cleaning robot 100 to move underwater. The rotary brush assembly 30 is installed on the wheels 20; the rotary brush assembly 30 includes a mounting seat 31 and a brush 32. The mounting seat 31 is connected to the wheels 20, and the brush 32 is movably connected to the mounting seat 31; by movably connecting the brush 32 to the mounting seat 31, it is ensured that in the cleaning state, that is, when cleaning the inner wall of the pool, the brush 32 unfolds to clean the dirt on the inner wall of the pool, and in the non-cleaning state, that is, when storing the underwater cleaning robot 100, the brush 32 is folded and stored to reduce the space occupied by the rotary brush assembly 30, thereby facilitating the transportation and storage of the underwater cleaning robot 100. Among them, in the cleaning state, at least a part of the brush 32 protrudes beyond the outer curved surface of the wheels 20 to ensure that during the movement of the wheels 20 along the corner of the inner wall of the pool, the brush 32 will clean the corner with a right-angled structure, thereby eliminating cleaning dead corners and improving the cleaning effect.

[0046] Further, the vehicle body 10 is the core load-bearing component of the underwater cleaning robot 100. A turbine (not shown in the figure) is provided inside the vehicle body 10. The turbine rotates to drive the water in the pool to pass through the vehicle body 10. The vehicle body 10 filters the dirt mixed in the passing water flow to collect the dirt into the vehicle body 10 uniformly, so as to realize the cleaning operation of the pool. It can be understood that the shape and structure of the vehicle body 10 can be modified according to actual use needs, and the specific shape and structure of the vehicle body 10 are not limited here, as long as the vehicle body 10 can support and fix other components.

[0047] Further, the wheels 20 are arranged on both sides of the vehicle body 10. The wheels 20 can rotate relative to the vehicle body 10, and the underwater cleaning robot 100 is driven to move in the pool by the rotation of the wheels 20. It can be understood that the wheels 20 are cylindrical, and the wheels 20 can directly abut against the inner wall of the pool, and then the underwater cleaning robot 100 is moved by the friction force between the wheels 20 and the inner wall of the pool; in another embodiment, a track can also be sleeved on the outside of the wheels 20, gears are meshed with the track, the rotation of the wheels 20 drives the track to rotate, and the track abuts against the inner wall of the pool, and then the underwater cleaning robot 100 is moved by the friction force between the track and the inner wall of the pool. It can be understood that the specific structure and driving method of the wheels 20 are not limited here, as long as the underwater cleaning robot 100 can move in the pool through the wheels 20.

[0048] Furthermore, the rotary brush assembly 30 is installed on the side of the wheel 20 away from the vehicle body 10. The rotary brush assembly 30 rotates together with the wheel 20, so that when the wheel 20 moves along the corner of the pool, the right-angle structure at the corner can be cleaned by the rotary brush assembly 30, thus avoiding cleaning dead corners. In this embodiment, a slot 311 is provided on the mounting base 31. The slot 311 is in the shape of a long strip-shaped groove and extends from the outer edge of the mounting base 31 towards the inside of the mounting base 31. One end of the brush 32 is inserted into the slot 311, and the folding and unfolding operations of the brush 32 are realized by moving the brush 32 in the slot 311. Among them, Figure 2 the position of the brush 32 shown is the folded position, corresponding to the position where the brush 32 is in the non-cleaning state; Figure 3 the position of the brush 32 shown is the unfolded position, corresponding to the position where the brush 32 is in the cleaning state.

[0049] Furthermore, the brush 32 includes a plug-in part 321, a brush part 322, an extension part 323 and a pushing part 324. The plug-in part 321 is in a long strip shape and is slidably arranged in the slot 311; the brush part 322 is arranged on the side of the plug-in part 321 close to the outer edge of the wheel 20, and the brush part 322 is used for cleaning the dirt on the inner wall of the pool; the extension part 323 is arranged in a long strip shape on one side of the plug-in part 321, and the extension part 323 extends from the plug-in part 321 towards the outside of the mounting base 31, and the extension part 323 passes through the mounting base 31 and is connected to the pushing part 324; the pushing part 324 is arranged at the end of the extension part 323 away from the plug-in part 321, and the pushing part 324 is used for being pushed by hand, so that in the cleaning state, the plug-in part 321 is pushed by the pushing part 324 to move towards the outside of the outer edge of the wheel 20, so that at least part of the brush part 322 protrudes outside the outer edge of the wheel 20, and then the brush part 322 is driven by the wheel 20 to rotate to clean the outside of the wheel 20. When the wheel 20 moves along the corner of the pool, the dirt at the corner can be swept up by the brush 32. In the non-cleaning state, the plug-in part 321 is pushed by the pushing part 324 to move towards the center of the wheel 20, so that the brush part 322 is folded and stored within the outer edge range of the wheel 20, thereby protecting the rotary brush assembly 30 and also reducing the space occupied by the rotary brush assembly 30, thus facilitating the transportation and storage of the underwater cleaning robot 100.

[0050] Further, a guiding hole 312 is provided on the mounting base 31. The guiding hole 312 is in a strip shape and extends in the same direction as the slot 311. The guiding hole 312 is opened on the side of the mounting base 31 away from the vehicle body 10. The guiding hole 312 communicates with the slot 311. The extending portion 323 is inserted into the guiding hole 312 to guide the movement of the brush 32 relative to the mounting base 31, thereby improving the stability of the movement of the brush 32 relative to the mounting base 31. In this embodiment, clamping openings 313 are respectively provided at two ends of the guiding hole 312 in the extending direction. The clamping opening 313 is in a groove shape and is used for clamping the extending portion 323 to clamp the brush 32 at a preset position. The positions of the clamping openings 313 at both ends of the guiding hole 312 respectively correspond to the positions of the brush 32 in the cleaning state and the non-cleaning state. By clamping the extending portion 323 through the clamping opening 313, the stability of maintaining the brush 32 at the positions in the cleaning state and the non-cleaning state is improved.

[0051] Further, the side surface of the brush 32 away from the vehicle body 10 relative to the wheel 20 is inclined. The included angle between the brush 32 and the outer side surface of the wheel 20 is from ten degrees to eighty degrees to ensure the cleaning effect on the right-angle structure. In this embodiment, the number of the brushes 32 is at least two, and the brushes 32 are arranged at intervals around the mounting base 31 to ensure the cleaning effect.

[0052] Please refer to Figures 5 to 9 , for the underwater cleaning robot 200 according to another embodiment of the present invention, the difference from the underwater cleaning robot 100 in the first embodiment lies in the specific structure of the rotary brush assembly 30a. The underwater cleaning robot 200 in this embodiment includes a knob 33. The knob 33 is connected to the brush 32a. The knob 33 rotatably connects the brush 32a to the mounting base 31a, and the folding and unfolding operations of the brush 32a are realized by rotating. Among them, Figure 5 the position of the brush 32a shown in Figure 6 is the folding position, corresponding to the position where the brush 32a is in the non-cleaning state;

[0053] Further, the brush 32a includes a torsion part 325 and a brush body part 326. The torsion part 325 is in a long strip shape. One end of the torsion part 325 is hinged to the mounting seat 31a, and the other end of the torsion part 325 is connected to the brush body part 326. By rotating the torsion part 325, the setting position of the brush body part 326 is adjusted, and thus the brush body part 326 is switched between the cleaning state and the non-cleaning state. In this embodiment, a through hole 315 is provided on the mounting seat 31a. The through hole 315 is in the shape of a circular through hole, and the through hole 315 is provided at the hinged position of the torsion part 325 and the mounting seat 31a. The knob 33 passes through the through hole 315 and is connected to the torsion part 325 to hinge the torsion part 325 and the mounting seat 31a.

[0054] Further, a positioning groove 316 is provided on the inner side wall of the through hole 315. The positioning groove 316 is provided in a groove-like structure. A positioning block 331 is provided on the side wall of the knob 33. The positioning block 331 is in a convex block shape, and the setting position of the positioning block 331 corresponds to that of the positioning groove 316. The positioning block 331 is used to be snapped into the positioning groove 316 to snap the knob 33 at a preset position. In this embodiment, the number of the positioning grooves 316 is two, and the two positioning grooves 316 respectively correspond to the positions of the positioning block 331 when the brush 32a is in the cleaning state and the non-cleaning state. Thus, by snapping the positioning block 331 into the positioning groove 316, the stability of the brush 32a in maintaining the positions in the cleaning state and the non-cleaning state is improved.

[0055] Further, a limiting block 317 is provided on the inner side wall of the through hole 315. The limiting block 317 is provided in a convex block shape and extends from the inner side wall of the through hole 315 towards the direction close to the knob 33. A limiting groove 332 is provided on the side wall of the knob 33. The limiting groove 332 is provided in a circular arc-shaped groove on the outside of the knob 33, and the setting position of the limiting groove 332 corresponds to that of the limiting block 317. The limiting block 317 slides in the limiting groove 332. Through the structures of the limiting block 317 and the limiting groove 332, the rotation angle of the knob 33 is limited to ensure that the brush 32a connected to the knob 33 can only be switched between the positions in the cleaning state and the non-cleaning state. By means of abutting and limiting, the reliability of the brush 32a in switching between the positions in the cleaning state and the non-cleaning state is improved.

[0056] In summary, the embodiment of the present utility model provides an underwater cleaning robot 100, and its beneficial effects are as follows:

[0057] By installing the rotary brush assembly 30 on the wheel 20, in the cleaning state, at least part of the brush 32 protrudes from the outer curved surface of the wheel 20. In this way, when the wheel 20 moves along the corner of the pool, the brush 32 can clean the dirt at the right-angled corner of the pool, eliminating the cleaning dead angle of the underwater cleaning robot 100, and thus improving the cleaning effect.

[0058] Through a push-pull telescopic structure or a rotary folding structure, it is ensured that the brush 32 can protrude from the outer curved surface of the wheel 20 in the cleaning state, and the brush 32 can be folded and stored in the non-cleaning state, thereby protecting the brush 32 and extending the service life of the rotary brush assembly 30; the folding and storage structure of the brush 32 can reduce the space occupied by the rotary brush assembly 30, thereby facilitating the transportation and storage of the underwater cleaning robot 100.

[0059] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0060] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
