working principle

The motor 12 starts to drive the fan blade 14 to rotate, and the fan blade 14 rotates to suck the dust outside the processing cylinder 10 into the processing cylinder 10 through the inlet 11, and the two trapezoidal telescopic plates 37 are pushed to the two sides by the air volume entering the dust into the telescopic seat. 36 , the dust enters the rotating drum 30 through the gap between the two trapezoidal telescopic plates 37 . The dust first filters out the larger particles in the dust through the filter cartridge 17; at the same time, the downward force of the dust on the telescopic seat 36 drives the rotating cylinder 30 to move downward and rotate, and the rotating cylinder 30 moves downward and rotates to drive the soft brush The block 34 and the hard brush block 35 move downward and rotate. First, the hard brush block 35 is rotated to clean the holes of the filter cartridge 17 in a small area, and then the soft brush block 34 is rotated to further clean the large area of the holes of the filter cartridge 17. Through the elastic force of the torsion spring 33 is greater than the downward thrust of the dust, the torsion spring 33 drives the rotating cylinder 30 to rotate and move upward, and the torsion spring 33 and the dust push the telescopic seat 36 downward, driving the rotating cylinder 30 to move up and down in a spiral to the filter cylinder. 17 holes for cleaning. Then the dust moves down along the cylinder 18 and the filter cartridge 17 to between the first fixed plate 19 and the second fixed plate 38, and the dust enters the filter bag 20 through the first fixed plate 19 for secondary filtration and removal. The fine particles inside, and the purified air is ejected through the outlet 21 .

The rotation of the output end of the motor 12 drives the eccentric wheel 15 to rotate, and the eccentric wheel 15 rotates to squeeze the movable plate 16 downward. The movable plate 16 moves down smoothly through the four bumps 23 , and the bumps 23 move downward and drive the piston plate 25 at the same time. Moving down, the piston plate 25 seals and slides in the water cavity 26, and the water in the water tank 27 is sucked into the water cavity 26 through the one-way valve 28 through the action of the piston; the movable plate 16 moves down to drive the filter cartridge 17 and a plurality of filter bags. 20 moves downward; when the eccentric wheel 15 rotates without squeezing the movable plate 16, the four hydraulic telescopic rods 24 push the four bumps 23 to move upward, and the upward movement of the bumps 23 drives the movable plate 16 to move upward, and the movable plate 16 moves upward. The movement drives the filter cartridge 17 and the plurality of filter bags 20 to move upward, and the particles on the filter cartridge 17 and the filter bags 20 are shaken and cleaned up by moving the movable plate 16 up and down, and the bump 23 moves upward to push the piston plate 25 to move upward, The upward movement of the piston plate 25 pushes the water in the water chamber 26 to be atomized and sprayed by the atomizing nozzle 29 to further reduce dust on the air sprayed from the outlet 21 .
