[0046] See also Figures 1 to 5 , is a roller brush 100 of an embodiment of the utility model, comprising a roller 10, a brush body 20 and a driving member 30. The roller 10 is the main supporting component of the roller brush 100, and the roller 10 is used to support the brush body 20. The brush body 20 is sleeved on the outside of the roller 10, and the brush body 20 is used to clean the stains and garbage in the external pool. The brush body 20 includes a first brush bar 21 and a second brush bar 22, and the first brush bar 21 and the second brush bar 22 are both extended in a spiral shape. The spiral direction of the first brush bar 21 is opposite to the spiral direction of the second brush bar 22, and a confluence area 50 is formed between the first brush bar 21 and the second brush bar 22. When the spiral first brush bar 21 and the second brush bar 22 rotate, they will push the water flow to move along the spiral path, and the spiral directions of the first brush bar 21 and the second brush bar 22 are opposite, so that the water flow on both sides will be concentrated to the middle confluence area 50, thereby effectively preventing the stains and garbage from leaking out and ensuring the cleaning effect. The driving member 30 is connected to the drum 10, and the driving member 30 drives the drum 10 to rotate, and the rotation of the drum 10 drives the brush body 20 to rotate, thereby cleaning the stains and garbage in the external pool.

[0047] Furthermore, the roller 10 is in a circular tube shape, and the roller 10 is arranged around the outside of the driving member 30. One end of the roller 10 is connected to the driving member 30, and the roller 10 rotates along its own axis. In this embodiment, the roller brush 100 also includes a side cover 40. The side cover 40 is a circular plate-shaped structure, and the side cover 40 is connected to the roller 10. The side cover 40 is arranged on one end of the roller 10 to improve the beauty of the overall roller brush 100, and effectively prevent garbage from entering the interior of the roller 10, affecting the normal operation of the driving member 30, and improving the stability of the operation of the roller brush 100.

[0048] Furthermore, the brush body 20 also includes a first barrel 23 and a second barrel 24. The first barrel 23 and the second barrel 24 are both in the shape of a circular tube, and the first barrel 23 and the second barrel 24 are sleeved on the outside of the drum 10 to install the brush body 20 on the drum 10. In this embodiment, the first barrel 23 is connected to the first brush strip 21 as a whole, the second barrel 24 is connected to the second brush strip 22 as a whole, and the confluence area 50 is located between the first barrel 23 and the second barrel 24, that is, the brush body 20 is a split structure. In another embodiment, the first barrel 23 and the second barrel 24 are an integral piece, that is, the brush body 20 is an integral structure, the first barrel 23 and the second barrel 24 are connected to form an integral circular tubular structure, and are sleeved on the outside of the drum 10.

[0049] Further, the number of the rollers 10 is two, one of which is inserted into the first barrel 23, and the other is inserted into the second barrel 24, that is, one roller 10 drives the first barrel 23 and the first brush strip 21 to rotate together, and the other roller 10 drives the second barrel 24 and the second brush strip 22 to rotate together. In another embodiment, only one roller 10 is provided, and the first barrel 23 and the second barrel 24 are both sleeved on the outside of the same roller 10, so that the roller 10 drives the first barrel 23 and the second barrel 24 to rotate synchronously at the same time.

[0050] Furthermore, one end of the driving member 30 is connected to the roller 10, and the side cover 40 is provided at the end of the roller 10 connected to the driving member 30, and the other end of the driving member 30 is connected and fixed to the outside world, so as to realize the connection and fixation of the roller brush 100 to the outside world; the number of the driving members 30 is two, and the driving members 30 are connected to the rollers 10 one by one. In this embodiment, the driving member 30 is a motor, and the roller 10 and the driving member 30 are both provided with two, and the two driving members 30 respectively drive the two rollers 10 to rotate relatively independently, the first cylinder 23 is connected to one roller 10, and the second cylinder 24 is connected to the other roller 10, so that the first brush strip 21 and the second brush strip 22 can rotate at the same speed or at a differential speed, thereby meeting the use requirements under different working conditions and improving the adaptability of the roller brush 100. It can be understood that by connecting the first cylinder 23 and the second cylinder 24 as a whole, or by sleeve-arranging the first cylinder 23 and the second cylinder 24 on the same drum 10, the synchronous rotation of the first brush strip 21 and the second brush strip 22 can be achieved by one driving member 30, which can save parts and reduce processing costs, and can also achieve the effect of concentrating the water flow on both sides to the middle confluence area 50. Preferably, the first cylinder 23 and the second cylinder 24 adopt a split structure, and two drums 10 are provided, one drum 10 is connected to the first cylinder 23, and the other drum 10 is connected to the second cylinder 24. Two driving members 30 are correspondingly provided, and the driving members 30 are connected to the drums 10 one by one to meet the practical needs of different working conditions. Only the preferred embodiment structure is shown in the drawings of this application. It is understandable that an embodiment in which an integrated brush body 20 is used, or the first cylinder 23 and the second cylinder 24 are sleeved on the same drum 10 to achieve synchronous driving of the first brush strip 21 and the second brush strip 22 by a driving member 30 also falls within the protection scope of this application.

[0051] Furthermore, a slot 15 is provided on the outer wall of the drum 10, and a clip strip 25 is provided on the inner wall of the brush body 20. The slot 15 is in the shape of a long strip groove extending along the axis direction of the drum 10, and the clip strip 25 is in the shape of a long strip. The clip strip 25 is provided corresponding to the slot 15, and the clip strip 25 is correspondingly provided in the slot 15 to improve the matching strength between the drum 10 and the brush body 20, and to prevent the brush body 20 and the drum 10 from being relatively displaced during the rotation of the drum 10. In this embodiment, the number of the slots 15 is multiple, and the multiple slots 15 are provided at intervals around the drum 10. The number of the clip strips 25 and the slots 15 is the same, and the clip strips 25 are respectively inserted into each slot 15 to improve the reliability of the connection between the drum 10 and the brush body 20.

[0052] Furthermore, the first brush strip 21 includes a large diameter end 26 and a small diameter end 27. The large diameter end 26 is arranged on the side of the first brush strip 21 close to the drum 10, and the large diameter end 26 is connected to the first cylinder 23, and the small diameter end 27 is arranged on the side of the first brush strip 21 away from the drum 10; in the cross-sectional direction of the first brush strip 21, the width dimension of the large diameter end 26 is greater than the width dimension of the small diameter end 27, so that the hardness of the side of the first brush strip 21 away from the first cylinder 23 is smaller, thereby reducing the impact load of the water flow on the first brush strip 21 during the rotation of the brush body 20, thereby increasing the service life of the first brush strip 21. Furthermore, the first brush bar 21 is arranged in an arc shape between the large diameter end 26 and the small diameter end 27, so that when the first brush bar 21 rotates with the first cylinder 23, the first brush bar 21 pushes the water flow to the confluence area 50 in a spiral shape, and the water flow and the first brush bar 21 contact position will produce a certain rotation, thereby effectively reducing the turbulence generated during the rotation of the brush body 20, preventing the leakage of stains and garbage, and improving the cleaning effect. In this embodiment, the second brush bar 22 has the same structure as the first brush bar 21, and the specific structure of the second brush bar 22 is not repeated here. The second brush bar 22 and the first brush bar 21 are symmetrically arranged relative to the confluence area 50.

[0053] The utility model also provides an underwater cleaning robot 200, which includes a body 90 and the above-mentioned roller brush 100. The body 90 is provided with a sewage suction port 95, which is used to suck the stains and garbage in the pool into the body 90, and then filter and collect the stains and garbage to achieve the cleaning operation of the pool. The roller brush 100 is installed on the body 90, and the driving member 30 of the roller brush 100 is connected and fixed to the body 90. The confluence area 50 of the roller brush 100 is correspondingly arranged with the sewage suction port 95, so as to send the water flow and the stains and garbage concentrated in the confluence area 50 into the sewage suction port 95 together, effectively preventing the leakage of the stains and garbage, and improving the cleaning effect of the underwater cleaning robot 200.

[0054] In summary, the embodiment of the utility model provides a roller brush 100, which has the following beneficial effects:

[0055] By providing the first brush bar 21 and the second brush bar 22 with opposite spiral directions, a confluence area 50 is formed between the first brush bar 21 and the second brush bar 22 during the rotation of the brush body 20, and dirt and garbage will gather in the confluence area 50, thereby preventing the dirt and garbage from leaking out and improving the cleaning effect.

[0056] By providing the large diameter end 26 and the small diameter end 27, the hardness of the first brush strip 21 and the second brush strip 22 away from the drum 10 is greater than the hardness of the side close to the drum 10, thereby effectively reducing the load borne by the brush body 20 during rotation and improving the service life.

[0057] By setting the cross-sections of the first brush bar 21 and the second brush bar 22 to be arc-shaped, when the brush body 20 rotates, the water flows between the spiral gaps not only to the confluence area 50, but also to a certain extent on its own, thereby effectively reducing the turbulence generated during the rotation of the brush body 20, preventing the leakage of stains and garbage, and improving the cleaning effect.
