[0002] Pool cleaning robots are used to clean dirt in swimming pools or water bodies. According to the different cleaning parts, they can be divided into surface cleaning robots and bottom cleaning robots. Surface cleaning robots mainly consider the ability to float on the water surface, while bottom cleaning robots need to consider sinking to the bottom of the water and being able to walk on the bottom of the water. Regardless of the type of the above pool cleaning robot, it includes an organism and a cleaning device.

[0003] In addition to cleaning the water surface and the bottom of the water, the side walls of the swimming pool also need to be cleaned. However, neither the surface cleaning robot nor the bottom cleaning robot can walk on the side walls to complete the cleaning. At this time, a swimming pool cleaning robot that can climb the wall is needed for cleaning. There are already swimming pool cleaning robots that can climb walls in the prior art, but it takes a lot of energy to attach or adsorb the swimming pool cleaning robot on the wall of the side wall. The cable-free swimming pool cleaning robot has a low cleaning efficiency and no external power supply, resulting in a short battery life. Although the cabled swimming pool cleaning robot has an external power supply for continuous power supply, it is inconvenient to use and also has the problem of low cleaning efficiency.

[0004] Existing pool cleaning robots often use rolling brushes for rolling cleaning, but the existing rolling brushes are easy to get entangled with hair, which affects the cleaning efficiency and requires frequent shutdown to remove hair. Therefore, how to improve the structure of the pool cleaning robot to improve the cleaning efficiency is a technical problem that technicians in this field need to consider. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The purpose of the utility model is to provide a roller brush body and a roller brush assembly thereof to solve the problems existing in the prior art. Through the combined arrangement of the brush and the soft film, the entanglement of hair can be minimized or eliminated while ensuring the cleaning effect, the cleaning efficiency can be improved, and the robot can be guaranteed to have a long-lasting cleaning ability.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figures 1 to 6As shown, the utility model provides a roller brush body 31, including a barrel 313 and a brush 311 and a soft film 312 arranged on the surface of the barrel 313. The brush 311 is composed of a plurality of bristles, and has a good cleaning effect, but is easy to be entangled with hair. If it is not cleaned in time, the cleaning effect will be greatly reduced. The soft film 312 can be made of rubber or silicone material, which is soft in texture and has a relatively poor cleaning effect, but is not easy to be entangled with hair. Through the combination of the brush 311 and the soft film 312, it is possible to minimize or eliminate the entanglement of hair on the basis of ensuring the cleaning effect, and ensure that the robot has a long-lasting cleaning ability. Specifically, when the brush 311 and the soft film 312 are set, the brush 311 and the soft film 312 are respectively arranged at intervals in the axial direction of the barrel 313, that is, the brush 311 at the same axial position has an interval, and the soft film 312 at the same axial direction has an interval. At the same time, the brush 311 and the soft film 312 are distributed at intervals in the circumferential direction of the barrel 313.

[0029] The roller brush body 31 of the utility model is provided with both a brush 311 and a soft plastic sheet 312. Through the combined arrangement of the brush 311 and the soft plastic sheet 312, the advantages of the good cleaning effect of the brush 311 and the difficulty of the soft plastic sheet 312 in entanglement with hair can be combined. On the basis of ensuring the cleaning effect, the entanglement of hair can be minimized or eliminated, the cleaning efficiency can be improved, and the robot can be guaranteed to have a long-lasting cleaning ability.

[0030] The spacing gaps of the brushes 311 in any axial direction are arranged in a staggered manner with the spacing gaps of the brushes 311 in another adjacent axial direction, so that when the roller brush body 31 rolls one circle, the brushes 311 can completely cover the wall surface or bottom surface to be cleaned, achieving a better cleaning effect. In addition, the spacing gaps of the soft plastic sheet 312 in any axial direction are arranged in a staggered manner with the spacing gaps of the soft plastic sheet 312 in another adjacent axial direction, so that when the roller brush body 31 rolls one circle, the soft plastic sheet 312 can completely cover the wall surface or bottom surface to be cleaned, achieving a better cleaning effect.

[0031] The brushes 311 and the soft plastic sheets 312 are radially distributed on the outer surface of the barrel 313. The interval between adjacent brushes 311 in the circumferential direction of the barrel 313 is larger than the interval between adjacent soft plastic sheets 312 in the circumferential direction. That is, the interval between brushes 311 is relatively large, which can further reduce the possibility of hair entanglement. In specific configuration, three groups of brushes 311 can be evenly distributed in the circumferential direction of the barrel 313, and multiple groups of soft plastic sheets 312 are arranged between adjacent brushes 311 in the circumferential direction.

[0032] Recombination Figures 1 to 6As shown, the utility model also provides a roller brush assembly 3 using the roller brush body 31 as described above, the roller brush assembly 3 includes a support shaft 32 and a roller brush body 31 rotatably arranged on the support shaft 32, the support shaft 32 is used to be installed on the body 1, and the body 1 can be the main structure of the wall-climbing swimming pool cleaning robot. The roller brush body 31 can rotate freely under the support of the support shaft 32, and when the roller brush body 31 is connected to the driving structure 2, it can be driven by the driving structure 2 to rotate. The roller brush body 31 can be provided with two sections on the support shaft 32, and the two sections of the roller brush body 31 are respectively connected to the corresponding driving structure 2. The roller brush body 31 includes a barrel 313, and a support plate 314 is provided at the end of the barrel 313, and the support plate 314 is rotatably arranged on the support shaft 32. By setting two sections of the roller brush body 31, each section of the roller brush body 31 can be connected to the power of the walking component on the same side of the wall-climbing pool cleaning robot, and the walking motor of the walking component can be used as a power source to drive the roller brush body 31 to operate, so that the roller brush body 31 and the walking component on the same side can be accelerated and decelerated synchronously. By controlling the walking motors on different sides to have different speeds, the steering of the body 1 can be controlled. On the basis of the synchronous acceleration and deceleration of the roller brush body 31 and the walking component on the same side, the steering can be made more flexible, the turning radius can be smaller, and the walking path can be better controlled, thereby reducing the energy consumption during path change and improving the cleaning efficiency. Due to better control of movement and improved cleaning efficiency, a larger area can be cleaned on the basis of the energy provided by the battery of the same capacity, which is equivalent to improving the endurance.

[0033] The transmission member 33 is included, and the transmission member 33 is used to connect the roller brush body 31 and the driving structure 2, and the transmission member 33 can transmit power to the roller brush body 31. Specifically, the transmission member 33 is rotatably sleeved on the support shaft 32, and the transmission member 33 includes a rotation output part, a support part and a rotation input part connected in sequence axially, and the rotation output part is fixedly connected with the support disk 314, for example, by screw connection, welding connection or shaft pin matching connection, etc., but preferably by a detachable connection method, which is convenient for replacing and repairing the roller brush body 31. The support part is used to be rotatably connected to the machine body 1, and the support part can rotate freely relative to the machine body 1, that is, when the roller brush body 31 can be driven to rotate by the transmission member 33, it can be rotated relative to the machine body 1. At this time, it can be known that the roller brush body 31 formed by the support disk 314 and the cylinder 313 rotates relative to the support shaft 32, and at the same time, the roller brush body 31 rotates relative to the machine body 1 through the transmission member 33. The rotation input part is used to connect the driving structure 2, for example, by a coupling, gear meshing or belt transmission, etc. The driving structure 2 may include a device such as a motor for active driving.

[0034] For the specific connection structure between the rotating output part and the roller brush body 31, the following scheme can be adopted: a polygonal hole 3141 is opened in the middle of the support plate 314, and the rotating output part adopts a polygonal column 331. The polygonal column 331 can be inserted into the polygonal hole 3141 and matched with it. When the polygonal column 331 rotates, the roller brush body 31 can be driven to rotate through the support plate 314.

[0035] For the specific connection structure between the support part and the body 1, the following scheme can be adopted: a bearing hole 11 is provided on the body 1, and the support part adopts a circular column 332. The circular column 332 is sleeved with a bearing 4, and the bearing 4 is installed in the bearing hole 11, so that the body 1 is used to support the rotation of the transmission member 33. At the same time, the transmission member 33 provides rotation support for the support shaft 32.

[0036] For the specific connection structure between the rotation input part and the driving structure 2, the following scheme can be adopted. The rotation input part adopts a bevel gear, which can also be called a bevel gear. It is only a difference in name and should not be used as a structural constraint. Functionally, the vertical change of the transmission direction is within the protection scope of the present utility model. The driving structure 2 includes a transmission rod 25 and a driving motor. The two ends of the transmission rod 25 are respectively connected to the bevel gear and the driving motor. When the driving motor rotates, the power is transmitted to the rotation input part through the transmission rod 25. The driving motor is mounted on the body 1 for fixing. More specifically, the rotation input part can adopt a fourth bevel gear 24. The two ends of the transmission rod 25 are coaxially connected to the second bevel gear 22 and the third bevel gear 23, respectively. The driving motor is connected to the first bevel gear 21. The first bevel gear 21 meshes with the second bevel gear 22, and the third bevel gear 23 meshes with the fourth bevel gear 24. The driving motor rotates to drive the first bevel gear 21 to rotate. The meshing of the first bevel gear 21 and the second bevel gear 22 changes the rotation direction and transmits it to the front of the machine body 1, and transmits the rotation to the third bevel gear 23 through the transmission rod 25. The meshing of the third bevel gear 23 and the fourth bevel gear 24 changes the rotation direction and transmits the rotation to the roller brush body 31, finally driving the roller brush body 31 to rotate.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
