[0024] Embodiment

[0025] As Figure 1As shown in the figure, a cleaning brush for a cleaning robot includes a housing 1 and a connecting handle 2. The housing 1 is hinged to the connecting handle 2. A rotary brush 3 and a motor 4 are arranged in the inner cavity of the housing 1. The rotary brush 3 is rotationally fitted relative to the housing 1 and is driven by the motor 4. A plurality of rubber scraping strips are axially arranged on the periphery of the rotary brush 3. A window for the rotary brush 3 to extend downward is arranged at the front section of the lower surface of the housing 1. The inner cavity of the housing 1 is communicated with a negative pressure assembly through a negative pressure pipeline. A stop strip 5 is arranged at the bottom of the housing 1 behind the rotary brush 3, and the stop strip 5 contacts the ground.

[0026] Advantages of the present utility model:

[0027] During use, the connecting handle 2 is used to connect with components such as a robotic arm or a handle. The connecting handle 2 is hinged to the housing 1 for adjusting the relative angle. A rotary brush 3 driven by a motor 4 is arranged inside the housing 1. By rotating the rotary brush 3, stains are cleaned. The stop strip 5 arranged behind the rotary brush 3 can scrape out the stains that are not cleaned by the rotary brush 3, making the cleaning more convenient. Among them, the negative pressure pipeline can absorb the brushed stains by negative pressure. In this solution, the negative pressure assembly includes a sewage tank and a negative pressure fan. The top of the sewage tank is communicated with the negative pressure pipeline, and the top of the sewage tank is also communicated with the air inlet of the negative pressure fan. After the stains are sucked into the sewage tank by negative pressure, the water remains in the sewage tank for temporary storage.

[0028] The tail of the housing 1 is hinged to the connecting handle 2, which is convenient for adjusting the angle between the two.

[0029] Auxiliary wheels 6 are respectively rotatably arranged on both sides of the rear part of the housing 1 to facilitate the movement of the housing 1 and reduce friction.

[0030] The housing 1 includes a main housing 7, a front cover 8 and a tail cover 9.

[0031] The motor 4 is arranged inside the main housing 7. A roller notch 10 is arranged at the front part of the main housing 7. The rotary brush 3 is located in the roller notch 10. Both ends of the rotary brush 3 are rotationally fitted with the roller notch 10 respectively. The front cover 8 is buckled on the front and upper parts of the roller notch 10.

[0032] The tail cover 9 is buckled on the lower part and the tail of the main housing 7.

[0033] The main housing 7 is more convenient to assemble and has a reasonable structure.

[0034] A clamping plate 11 is arranged at the front part below the roller notch 10. The rotary brush 3 contacts the ground through the rear part below the roller notch 10. This is convenient for forming a separate cleaning space for the rotary brush 3 and concentrating on cleaning stains in a separate window.

[0035] The outer side of the main housing 7 is provided with a transmission space, the output end of the motor 4 is provided with a driving synchronous wheel 13 located in the transmission space, the rotating shaft of the roller brush 3 extends to the transmission space and is provided with a driven synchronous wheel 14, and the driving synchronous wheel 13 and the driven synchronous wheel 14 are connected by a synchronous belt 15. The space division with the roller brush 3 is independent, so as to prevent stains from entering the area of the synchronous belt 15 and affecting the transmission, thereby ensuring the stability of the transmission.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
