[0029] Specifically, dust falls on the first filter 15, and the first filter 15 retains the dust. After the air passes through the first filter 15, the air is filtered for the second time through the second filter 18 to improve the filtering effect. When the filter plate 14 needs to be cleaned, the limit ring 12 is pulled to move the limit ring 12 and then detach from the collection bin 7, and then the limit bin 13 is pulled to drive the top filter plate 14 to move. Under the action of the support rod 16, the bottom filter plate 14 is driven to move, so that the two filter plates 14 are detached from the collection bin 7, and then the first filter 15 and the second filter 18 are cleaned.
