When the end of the card block 602 is not engaged with the card slot 604, the two second springs 702 will extend at the same time to drive the positioning block 701 to move. The movement of the positioning block 701 will push the outer frame 501 out of the interior of the end cover 2, thereby facilitating the removal of the outer frame 501 and the filter screen 502 from the end cover 2. After removal, it is convenient to clean the filter screen 502, thereby effectively avoiding the blockage of the filter screen 502 and ensuring the filtration efficiency.
