When the work is carried out, No. three brush 24 stretches out the box 1 outside, sweeps the dust out of box 1 outside, and when No. three brush 24 got into box 1 inside once more, the brush hair of No. three brush 24 can be combed to the broach 132 that sets up, has reduced the accumulation of dust on No. three brush 24 brush hair, and combs under broach 132, and the effectual brush hair that has prevented No. three brush 24 from knoing the winding each other.

The specific working process is as follows:

the box body 1 is horizontally arranged, the detection device is arranged at the central part of the box body 1, the louver strips 12 are arranged at the upper half part of the box body 1, the louver strips 12 are inclined inwards, under the condition that air circulation is ensured, the inward inclined louver strips 12 can effectively prevent dust from entering the box body 1, and the baffle 131 arranged at the dust outlet 13 can effectively prevent external dust from entering; when external wind is strong, dust is easy to raise and enter the box body 1, at the moment, wind power drives the wind wheel 31 to rotate, so that the connecting shaft 32 is driven to rotate, the electromagnetic clutch 33 is arranged on the connecting shaft 32, the clutch can be controlled remotely, so that whether the worm 35 rotates or not is controlled, and the situation that the wind is strong is reduced, the wind wheel 31 drives the worm wheel 34 to rotate all the time, so that the first hair brush 22, the second hair brush 23 and the third hair brush 24 are abraded; when the connecting shaft 32 drives the worm 35 to rotate, the worm 35 drives the worm wheel 34 to rotate, and due to the high transmission ratio of the worm wheel 34 and the worm 35, even if the rotation speed of the worm 35 is high, the worm wheel 34 is driven slowly, so that the rotation speed of the rod piece 21 is high due to the high rotation speed of the worm wheel 34, and the second brush 23 and the third brush 24 are driven to rotate too fast, so that the situation that dust in the box body 1 is raised is avoided, when the worm wheel 34 rotates slowly, the rod piece 21 is driven to rotate slowly, the first brush 22 brushes the outer parts of the louver strips 12 slowly, so that the dust accumulation on the exposed louver strips 12 is reduced, meanwhile, the second brush 23 brushes the inner wall of the box body 1 slowly, so that the dust falls to the bottom of the box body 1, the third brush 24 also rotates slowly, and the length of the brush body of the third brush 24 is longer than the minimum distance between the rod piece 21 and the side wall of the box body 1, so that the third brush 24 rotates in the box body 1, the third brush 24 is in an inclined state, the inclined direction is far away from the rotation direction of the rod piece 21, the third brush and the second brush 23 form a certain angle, the torsion spring 241 is in a force accumulation state, and the third brush 24 is in contact with the inner wall of the box body 1 and the bottom of the box body 1 at the moment, so that the third brush 24 cleans dust on the inner wall of the box body 1 and the bottom of the box body 1 which are in contact with the third brush 24; the third brush 24 is inclined, so that the dust moves along the edge of the third brush 24 in the advancing process and is gathered at a position close to the inner wall of the box body 1, and the dust is easier to discharge; when the third brush 24 pushes the dust to move to the dust outlet 13, the torsion spring 241 is reset, the elastic force drives the third brush 24 to rotate by taking the rod 21 as the axis, so that the third brush 24 and the second brush 23 are positioned on the same horizontal plane, and in the process, a forward pushing force is generated to throw the dust out of the box body 1; when the third brush 24 enters the box body 1 again, the return spring is reset, the baffle 131 is reset, and the baffle 131 continuously blocks dust from entering; the second brush 23 and the third brush 24 continue to rotate, and the operation is repeated, so that the accumulation of dust in the box body 1 is reduced; in addition, the bottom surface of the box body 1 is arc-shaped and is bent upwards and provided with the drainage groove 14, so that dust is not easy to gather at the central part of the bottom of the box body 1, dead angles are not easy to generate due to the transition of the bottom surface of the box body 1 and the side wall surface of the box body 1 through arc-shaped curved surfaces, the dust is easier to discharge, when the rotating wheel 242 arranged at the bottom of the third brush 24 passes through the drainage groove 14, the rod piece 21 can vibrate, and therefore the accumulation of the dust on the first brush 22, the second brush 23 and the third brush 24 is reduced.
