[0024] Specific working principle:

[0025] When using the device, first install the exhaust fan 6 and the intake fan 7. During installation and use, first pull the limiting rod 9, then insert the mounting base 5 into the connecting base 2, so that the locking block 4 on the outer wall of the mounting base 5 inserts into the locking groove 3 on the outer wall of the connecting base 2. Next, rotate the mounting base 5 so that the locking block 4 engages at the end of the locking groove 3, and at the same time, the limiting rod 9 rotates to the limiting hole 12 on the side wall of the filter box 1. At this time, release the limiting rod 9, the spring 11 compresses the baffle 10, and thus drives the limiting rod 9 toward the limiting hole 12 on the side wall of the filter box 1, and engages into the limiting hole 12, thereby locking the two mounting bases 5 that are connected in a limiting manner. In use, the exhaust fan 7 draws outside air into the filter box 1, and after being filtered by the three filter components 13 inside the filter box 1, the purified air is discharged from the filter box 1 by the exhaust fan 6. At the same time, the servo motor drives the rotating rod 18 and the active helical gear 17 fixedly connected to the outside of the rotating rod 18 to rotate. Then, the meshing of the rotating active helical gear 17 and the driven helical gear 16 rotates the threaded rod 15 to adjust its rotation. Then, the threaded rod 15 drives the cleaning brush 14 to move back and forth, thereby cleaning the dust on the surface of the filter components 13. The dust that falls into the collection box 19 is collected and processed uniformly.
