[0032] In the utility model, the working steps of the device are as follows:

[0033] The first step: when the filter bag 2 needs to be cleaned, the driving motor 304 is started to drive the cam 305 and the protrusion 307 to rotate, so that one end of the protrusion 307 hits the vibration plate 303. After the force is applied, the vibration plate 303 moves toward the filter bag 2 and contacts it, and then the vibration plate 303 is driven to reset by the spring 302 and the telescopic rod 301. As the cam 305 continues to rotate, the vibration plate 303 can reciprocate and continuously hit the filter bag 2 to knock off the dust on its surface, thereby improving the cleaning effect of the filter bag 2. When the amplitude strength needs to be adjusted, the nut 309 is loosened to increase the distance between it and the cam 305, so that the position of the protrusion 307 can be moved, and the stud 308 can slide in the adjustment slot 306, so as to adjust the distance of the protruding part of the protrusion 307. After adjustment, the nut 309 is tightened to fix it, and the amplitude strength is adjusted by adjusting the distance of the protruding part of the protrusion 307.

[0034] The second step: the dust knocked down falls on the dust collecting hopper 5. Starting the fan 6 can suck the dust into the collecting box 7, and then the dust is intercepted by the filter 10. Opening the cleaning door 8 can centrally process the dust collected in the collecting box 7. When the fan 6 is running, the gas blown in by the fan 6 passes through the cleaning component 11, which can drive the box body 1101 to rotate. Under the action of the box body 1101, the transmission rod 1103 is driven to rotate, thereby driving the cleaning brush plate 1104 to rotate, cleaning the dust blocked on the surface of the filter 10 to avoid blockage of the filter 10.
