[0139] refer to Figure 3-Figure 12 In some embodiments, the second cleaning brush 129 and the first cleaning brush 127 are arranged along the length direction of the filter screen 121. In the projection of the height direction of the main body, the first cleaning brush 127 is arranged between the first roller 122 and the second cleaning brush 129, which can prevent dust on the first cleaning brush 127 from falling onto the second cleaning brush 129, and avoid dust accumulation on the second cleaning brush 129 to affect the cleaning effect of the first cleaning brush 127.

[0140] The second cleaning brush 129 is connected to the inner side of the box body 126 . The first cleaning brush 127 is rotated to make the first cleaning brush 127 contact the second cleaning brush 129 , so that the second cleaning brush 129 can remove dust adhered to the first cleaning brush 127 .

[0141] refer to Figure 13-Figure 15 In some embodiments, the second cleaning brush 129 is disposed below the first cleaning brush 127. The first cleaning brush 127 can rotate to contact the second cleaning brush 129, and the first cleaning brush 127 and the second cleaning brush 129 rub against each other to clean dust attached to the first cleaning brush 127, thereby improving the cleaning effect of the first cleaning brush 127 on the filter 121.
