[0052] Specifically, the driving motor 43 drives the first roller brush 41 to rotate, the first roller brush 41 drives the transmission mechanism 44, and the transmission mechanism 44 drives the second roller brush 42 to rotate, so that the rotation directions of the first roller brush 41 and the second roller brush 42 are opposite. Moreover, the rotation rates of the first roller brush 41 and the second roller brush 42 are the same.

[0053] The purpose of such arrangement is that, by Figure 5 It can be seen that when the rotation directions of the first roller brush 41 and the second roller brush 42 are opposite, the frictional forces of the first roller brush 41 and the second roller brush 42 on the opposite sides of the conveying belt 30 are towards the same direction, and the dirt falls along the same direction, which is convenient for collecting and processing the dirt after cleaning.

[0058] Specifically, in the embodiment, the transmission belt 443 is wound around the first transmission wheel 444 and the second transmission wheel 445 in a staggered manner. When the first transmission wheel 444 rotates clockwise, the transmission belt 443 rotates clockwise, and the second transmission wheel 445 rotates counterclockwise. Conversely, when the first transmission wheel 444 rotates counterclockwise, the second transmission wheel 445 rotates clockwise. The purpose of this arrangement is to achieve the effect that the rotation directions of the first roller brush 41 and the second roller brush 42 are opposite, and the rotation rates are the same, under the premise of using only one driving motor 43. The auxiliary wheel 442 is used to assist the transmission belt 443 to form a loop.
