When the inner end of the filter element contacts the outer surface of the push plate in the first telescopic groove, the inner end of the cover plate is inserted into the outer opening of the filter element. At this time, the inner sides of the cover plate are The second sealing ring in the second slot begins to seal the connection between the cover plate and the filter element to prevent dust from entering the interior of the filter element along the connection between the cover plate and the filter element. Then, the positioning blocks at the upper and lower ends of the inner side of the cover plate are aligned with the positioning grooves opened at the filter cartridge mounting opening on the surface of the dust box, and the toggle plate is toggled inwardly so that the toggle plate drives the fixing block to retract into the second telescopic groove. Then, the cover plate is pressed so that the cover plate pushes the outer front end of the filter element into the dust box and the positioning block is inserted into the positioning groove. At this time, the inner end of the filter element squeezes the push plate and extends into the first telescopic groove for a distance. At this time, the first sealing ring in the first slot on both sides of the front end of the first telescopic groove begins to seal the connection between the filter element and the first telescopic groove to prevent dust from entering the filter element along the connection between the filter element and the first telescopic groove. Finally, by loosening the toggle plate, the second spring in the second telescopic groove pops out the fixing block from the second telescopic groove through elastic force, and inserts it into the fixing groove aligned with the second telescopic groove to fix the cover plate, thus completing the replacement and installation.
