[0075] In use, the user pulls the insert rod 17 by hand, allowing one end of the insert rod 17 to enter the second slide groove 16 from the first slide groove 4, extending the first spring 18. At this time, the fixation of the slide plate 5 is released. Then, the user slides the slide plate 5 by hand, allowing it to slide within the first slide groove 4. When the slide plate 5 slides to the appropriate position, the inner cavity of the box 2 is exposed to the outside. The user then places the enamel cast iron furnace rack into the inner cavity of the box 2. Then, the user slides the slide plate 5 in the opposite direction, allowing it to slide along the first slide groove 4 in the reverse direction.

After the enamel cast iron furnace frame is sprayed, the user starts the air purifier 15, allowing the output end of the air purifier 15 to draw air out of the exhaust duct 14, creating a negative pressure in the exhaust duct 14. When a negative pressure is generated in the exhaust duct 14, the exhaust duct 14 will remove harmful gases from the inner cavity of the box 2 through the filter element 13, the exhaust pipe 9, and the suction head 7. When harmful gases pass through filter element 13, particulate impurities in the harmful gases are filtered out. When harmful gases pass through air purifier 15, harmful substances in the harmful gases are filtered out by air purifier 15 and discharged to the outside, purifying the harmful substances in the air and ensuring that the harmful substances in the air can be purified. When filter element 13 needs to be replaced after use, the user manually rotates the rotating rod 25, causing the rotating rod 25 to drive the gear 24 to rotate in the rotating groove 23, causing the gear 24 to drive the rack 20 to move in the third sliding groove 19, causing the rack 20 to drive one end of the second insert 22 out of the slot 10. Enter the third slide groove 19 and let the rack 20 compress the second spring 21. At this time, the fixation of the first insert 11 is released. Then, the user pulls the first insert 11 out of the slot 10 by hand, and then pulls the filter element 13 out of the second through groove 12 and replaces the filter element 13. After replacement, insert the replaced filter element 13 into the second through groove 12 and insert the first insert 11 into the slot 10. Then, the user releases the hand of rotating the lever 25, so that one end of the second insert 22 is inserted from the third slide groove 19 into the inner wall of the slot 10, ensuring that the first insert 11 can be fixed in the slot 10 and cannot move.
