[0025] When the activated carbon mesh plate 421 needs to be replaced, the square block 47 can be moved by pulling the square pull opening 471, so that the limiting block 48 can be disengaged from the slot 44. Then, the activated carbon mesh plate 421 with the filter frame 42 can be pulled out by the rectangular pull opening 431. The filter mesh plate 421 with the new filter frame 42 can be inserted into the rectangular through slot 41. Releasing the square pull opening 471 and using the force of the first spring 46, the limiting block 48 can be inserted into the slot 44 for fixation, making it convenient to replace the new activated carbon mesh plate 421.

[0026] The second spring 54 can be compressed by pulling the movable rod 52. After the movable rod 52 is released, the force of the second spring 54 will cause its end to contact the filter frame 42, thereby shaking the dust on the filter frame 42 into the collection box 12, preventing the filter frame 42 from becoming blocked and affecting the air flow. The shaken dust falls into the collection box 12. The limit on the collection box 12 can be released by rotating the bolt 13, and then the dust inside can be centrally processed.
