After the impurities and dirt are swept into piles, they are manually cleaned, and the cleaning efficiency is low. At the same time, during the cleaning process, since the roller brushes rotate in the same direction, dust is easily generated, and the cleaning effect is poor. Utility Model Content

[0003] The utility model aims to provide a swimming pool cleaning robot, which can clean impurities and dirt without manual work, has high cleaning efficiency, can avoid dust, and improve the cleaning effect.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a swimming pool cleaning robot, including a main body, which moves along a first direction, a sewage suction port is provided at the bottom of the main body, a first roller brush and a second roller brush are arranged at intervals along the first direction below the main body, the first roller brush and the second roller brush are rotatably connected to the main body, the sewage suction port is located between the first roller brush and the second roller brush, the rotation direction of the first roller brush is opposite to the rotation direction of the second roller brush, and the rotation directions of the first roller brush and the second roller brush are arranged toward the sewage suction port, and the rotation speed of the first roller brush is greater than the rotation speed of the second roller brush.

[0005] Furthermore, the first roller brush and the second roller brush have the same structure, the first roller brush comprises a roller brush shaft and cleaning blades, the cleaning blades extend radially outwardly along the roller brush shaft and are evenly spaced along the axial direction of the roller brush shaft on the outer wall of the roller brush shaft.

[0006] Furthermore, the cleaning blade is arranged on the roller brush shaft at an angle toward the dirt suction port, and the angle between the end surface of the cleaning blade and the axis of the roller brush shaft is in the range of 65°-85°.

[0007] Furthermore, the inclination angle of the cleaning blade of the first roller brush on the roller brush shaft is complementary to the inclination angle of the cleaning blade of the second roller brush on the roller brush shaft.

[0008] Furthermore, the rotation speed of the first roller brush is 1.5-6 times the rotation speed of the second roller brush.

[0009] Furthermore, dirt blocking strips are symmetrically arranged on both sides of the dirt suction port at the bottom of the main body.

[0019] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "inside", "outside", etc. used in the present invention to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred devices and elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0022] like Figure 1 As shown, a swimming pool cleaning robot according to a preferred embodiment of the utility model includes a body 1. For the convenience of description, the walking direction of the body 1 is defined as a first direction X. A sewage suction port 11 is provided at the bottom of the body 1. The sewage suction port 11 is connected to a sewage suction device (such as a sewage suction machine, a vacuum cleaner, etc.) in the body 1. The sewage suction port 11 sucks impurities and dirt into the body 1 without manual cleaning. In order to clean the bottom and side walls of the swimming pool, a first roller brush 2 and a second roller brush 3 are arranged at intervals along the first direction X below the body 1. The first roller brush 2 and the second roller brush 3 are rotatably connected to the body 1. In the prior art, the first roller brush 2 and the second roller brush 3 are driven by corresponding motors. Therefore, their specific structures are not described in detail. The sewage suction port 11 is located between the first roller brush 2 and the second roller brush 3. In order to facilitate the impurities and dirt brushed by the first roller brush 2 to quickly enter the sewage suction port 11, the distance from the first roller brush 2 to the sewage suction port 11 is less than the distance from the second roller brush 3 to the sewage suction port 11. After the first roller brush 2 brushes off the impurities and dirt from the bottom and the wall of the pool, most of the impurities and dirt enter the sewage suction port 11 with the rotation of the first roller brush 2, and there will be a very small part of the remaining impurities and dirt that do not enter the sewage suction port 11. In order to avoid the residue and to prevent the second roller brush 3 from rotating and bringing up the impurities and dirt to generate dust and cause secondary pollution, in this embodiment, the rotation direction of the first roller brush 2 is opposite to the rotation direction of the second roller brush 3, and the rotation directions of the first roller brush 2 and the second roller brush 3 are set toward the sewage suction port 11. The second roller brush 3 rotates to gather the remaining impurities and dirt toward the sewage suction port 11 for cleaning again, thereby improving the cleaning effect. Since the first roller brush 2 needs to brush off the impurities and dirt stubbornly attached to the bottom and side walls of the swimming pool and gather them, it needs to provide a large centrifugal force, and the second roller brush 3 only needs to gather the impurities and dirt scattered on the bottom of the pool, and the centrifugal force required is small. In order to save power resources, therefore, in this embodiment, the rotation speed of the first roller brush 2 is greater than the rotation speed of the second roller brush 3.

[0023] Furthermore, in order to simplify the structure of the first roller brush 2 and the second roller brush 3 and facilitate design, in the present embodiment, the first roller brush 2 and the second roller brush 3 have the same structure, and the first roller brush 2 includes a roller brush shaft and a cleaning blade. Specifically, the cleaning blade extends radially outward along the roller brush shaft and is evenly spaced along the axial direction of the roller brush shaft on the outer wall of the roller brush shaft.

[0024] Furthermore, in this embodiment, in order to drive the impurities and dirt to move to the dirt suction port 11, the cleaning blade is tilted on the roller brush shaft toward the dirt suction port 11, and the angle between the end surface of the cleaning blade and the axis of the roller brush shaft is between 65° and 85°. At the same time, in order to prevent the impurities and dirt from remaining after passing through the second roller brush 3, in this embodiment, the tilt angle of the cleaning blade of the first roller brush 2 on the roller brush shaft is complementary to the tilt angle of the cleaning blade of the second roller brush 3 on the roller brush shaft.

[0025] Furthermore, in this embodiment, the rotation speed of the first roller brush 2 is 1.5-6 times the rotation speed of the second roller brush 3. When the rotation speed of the first roller brush 2 is less than 1.5 times the rotation speed of the second roller brush 3, it is easy to offset the force of the body 1 moving forward, so that the swimming pool cleaning robot consumes a lot of power and reduces the walking speed. When the rotation speed of the first roller brush 2 is greater than 6 times the rotation speed of the second roller brush 3, the rotation speed of the first roller brush 2 is too fast and dust is easily generated.

[0026] Furthermore, in some embodiments, in order to prevent the impurities and dirt cleaned from the bottom and side walls of the swimming pool from being easily overflowed from both sides of the bottom of the body 1 when the roller brush is brought to the sewage suction port 11, and the impurities and dirt cannot be concentrated, thus affecting the cleaning efficiency, dirt blocking strips 4 are symmetrically provided on both sides of the sewage suction port 11 at the bottom of the body 1. Figure 3 , the dirt-blocking strip 4 extends along the first direction X, and one end of the dirt-blocking strip 4 is close to the first roller brush 2, and the other end is close to the second roller brush 3. Furthermore, in order to enhance the dirt-blocking effect of the dirt-blocking strip 4, blocking pieces 41 are evenly spaced along the first direction X on the end surface of the dirt-blocking strip 4 facing away from the main body 1. In order to further enhance the dirt-blocking effect, in the present embodiment, the dirt-blocking strip 4 is made of a flexible material, such as rubber or silicone material, which can produce a certain deformation and can fit tightly against the bottom surface of the swimming pool to prevent impurities and dirt from overflowing from the gap between the dirt-blocking strip 4 and the bottom surface of the swimming pool. Furthermore, the swimming pool cleaning robot needs to be fixed in position for cleaning the places where impurities and dirt are stubbornly attached, therefore, refer to Figure 1 , Figure 3 Rollers 5 are provided on both sides of the body 1. The rollers 5 are located below the body 1 and provide the body 1 with power to move forward, backward or turn. The rollers 5 are located between the first roller brush 2 and the second roller brush 3. The rollers 5 have a braking function for easy fixed cleaning.

[0027] In summary, the embodiment of the utility model provides a swimming pool cleaning robot, wherein a first roller brush 2 and a second roller brush 3 are arranged at intervals along a first direction X below a main body 1, and a sewage suction port 11 is located between the first roller brush 2 and the second roller brush 3. The rotation direction of the first roller brush 2 is opposite to that of the second roller brush 3, and the rotation directions of the first roller brush 2 and the second roller brush 3 are arranged toward the sewage suction port 11. Since the rotation directions of the first roller brush 2 and the second roller brush 3 are opposite, after the first roller brush 2 brushes impurities and dirt from the bottom or side wall of the swimming pool, the sewage suction port 11 sucks the impurities and dirt into the main body 1, without manual cleaning, and the cleaning efficiency is high. When the main body 1 is moving forward, the second roller brush 3 can gather the impurities and dirt that have not been sucked into the sewage suction port 11 toward the sewage suction port 11 again, so as to avoid causing dust, forming secondary pollution, and improving the cleaning effect.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
