[0034] In some embodiments, the dust-blocking brush includes a brush head, and the brush head is directly fixed to the support portion or the driving portion. Specifically, the brush head is fixed to the motor support column or the driving motor.

[0035] In some embodiments, the dust-blocking brush includes a brush head, a connecting portion, and a spring, wherein the brush head is movably connected to the connecting portion, and the spring connects the brush head and the connecting portion to apply a force to the brush head to move toward the brush column.

[0036] Figure 4 This is a schematic diagram of the structure of the dust-blocking brush in some embodiments of the present invention. Figure 4 The dust-blocking brush comprises a brush head 3021, a connecting part 3022 and a spring 3023. The connecting part 3022 comprises a connecting block 30221 and a connecting shaft 30222.

[0040] Figure 7 In some embodiments of the present invention Figure 6 Enlarged schematic diagram of the middle connection. Figure 7An adjusting groove 302213 is provided on the inner wall of the accommodating hole 302211, and the adjusting portion comprises an inner cylinder 30231, a blocking column 30232 and a reset spring 30233, a toggle block 302321 is provided on the blocking column 30232, the length of the blocking column 30232 is less than or equal to the depth of the adjusting groove 302213, the blocking column 30232 is arranged in the adjusting groove 302213, the reset spring 30233 is arranged between the blocking column 30232 and the adjusting groove 302213, the inner cylinder 30231 is arranged in the accommodating hole 302211, and a plurality of blocks 302311 are provided on the outer wall of the inner cylinder 30231. In a natural state, the elastic force of the return spring 30233 causes one end of the blocking column 30232 to extend out of the adjusting slot 302213, so that the blocking column 30232 can jam the blocking block 302311, thereby preventing the inner cylinder 30231 from rotating; when the toggle block 302321 is moved to drive the blocking column into the adjusting slot 302213, the blocking block 30232 loses the obstruction of the blocking column 30232, and the inner cylinder 30231 can rotate.

[0042] Reference Figure 7 , the inner cylinder 30231 is rotated counterclockwise, the deformation force of the spring 3023 increases, and the torque applied to the connecting shaft 30222 in the counterclockwise direction increases, thereby increasing the friction between the brush head 3021 and the brush column, which is more conducive to blocking the dust adsorbed on the brush column.

[0043] In some embodiments, the brush column includes an inner roller and a brush sleeve, and the brush sleeve is sleeved on the outer side of the inner roller.
