DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described and illustrated in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] The utility model embodiment provides a cleaning brush plate, referring to Figure 1 and Figure 2 As shown, the cleaning brush disc at least includes: a fixed bracket 1, a wedge block assembly 2, a driving assembly 3, an elastic assembly 4 and a brush disc assembly 5; the wedge block assembly 2 is fixedly connected to the fixed bracket 1 at an inclined angle from outside to inside; the driving assembly 3 passes through the wedge block assembly 2 and is connected to the fixed bracket 1; one end of the elastic assembly 4 is connected to the wedge block assembly 2, and the other end of the elastic assembly 4 is connected to the driving assembly 3; the brush disc assembly 5 is connected to the driving assembly 3, and the driving assembly 3 drives the brush disc assembly 5 to rotate. Among them, the wedge block assembly 2 provides forward power for the brush disc assembly 5, and the elastic assembly 4 drives the brush disc assembly 5 to adjust the angle adaptively. The cleaning brush disc disclosed by the utility model has a simple structure, can adapt to different forward speeds and can clean floors with different inclined surfaces, curved surfaces or anisotropic surfaces; since the brush disc assembly 5 has a certain adsorption force with the ground when rotating, by fixedly connecting the wedge block assembly 2 to the fixed bracket 1 at an inclined angle, the wedge block assembly 2 can provide the brush disc assembly 5 with forward power in the tangential direction, thereby changing the forward speed of the cleaning brush disc, and by arranging the elastic component 4, the brush disc assembly 5 can be adapted to floors with different inclined surfaces, curved surfaces or anisotropic surfaces through the elastic change of the elastic component 4, so that cleaning is cleaner and more comprehensive.

[0028] The outer and inner parts of the cleaning brush plate disclosed in the utility model are as follows Figure 1 As shown, the wedge block assembly 2 is fixedly connected to the fixed bracket 1 at an inclined angle from outside to inside, so that the cleaning brush disc can clean floors with different slopes, curved surfaces or anisotropic surfaces.

[0029] In some embodiments, the wedge block assembly 2 is detachable, and a suitable wedge block assembly 2 can be replaced according to different slopes, curves or anisotropic surfaces of the ground, and is easier to maintain and assemble.

[0030] Furthermore, the wedge block group 2 includes a first wedge block 21 and a second wedge block, the first wedge block 21 is arranged on one side of the fixed bracket 1, and the inclination angle of the first wedge block 21 is 3°~8°; the second wedge block 22 is arranged on the other side of the fixed bracket 1; the inclination angle of the second wedge block 22 is 3°~8°; wherein, the first wedge block 21 and the second wedge block 22 are symmetrically arranged. The utility model sets the inclination angle of the first wedge block 21 and the second wedge block 22 to 3°~8°. It is proved through multiple tests that 3°~8° can effectively ensure that the brush plate assembly 5 has good adsorption and adaptability to the ground and the travel speed. When the inclination angle is less than 3°, the decomposition force in the tangential direction generated by the wedge block assembly 2 is small, and the adsorption force between the brush plate assembly 5 and the ground is too large. If the adsorption force is too large, the travel speed will be too slow or even spin in place. When the inclination angle is greater than 8°, the decomposition force in the tangential direction generated by the wedge block assembly 2 is large, and the adsorption force between the brush plate assembly 5 and the ground is too small. The small adsorption force causes the travel speed to be too fast, so that the cleanliness cannot be guaranteed, so that the cleaning rate of the cleaning brush plate is greatly reduced. Therefore, the utility model adopts the first wedge block 21 and the second wedge block 22 of 3°~8° to greatly improve the cleaning rate of the cleaning brush plate.
