The cabinet door 2 is fixed to the machine body 1 by the locking handle 4 and the locking threaded rod 3, and the cabinet door 2 is closed. At this time, the exhaust fan 24 is started. 24 sucks dust into the machine body 1 through the exhaust pipe 25 and the suction cover 26, and uses the first filter plate 17 to filter out large dust particles in the inhaled air. The initially filtered air passes through the sieve holes on the first filter plate 17 and enters the purification area between the second filter plate 18 and the first filter plate 17. The water pump 22 is started, and the water pump 22 transports water in the water tank 19 to the spray head 23 through the connecting pipe 21. The spray head 23 sprays water mist, so that the fine dust in the dirty air is stained with water and precipitated on the second filter plate 18. After purification, The air passes through the sieve holes on the second filter plate 18 and is discharged to the outside through the air outlet pipe 27 to achieve the effect of purification and ventilation. The operator rotates the cleaning handle 16, and the cleaning handle 16 drives the cleaning threaded rod 13 to rotate. The cleaning threaded rod 13 drives the scraper 14 to move back and forth along the slide rail 15, thereby sweeping the precipitated dirt on the second filter plate 18 to both sides. When it is necessary to maintain or replace the device in the body 1, it is only necessary to rotate the locking handle 4 in the opposite direction to separate the locking handle 4 from the cabinet door 2, and then open the cabinet door 2 to complete the maintenance and replacement.
