Each limiting plate 4 is fixedly connected to an inclined block 5 outside. Each limiting plate 4 is fixedly connected to the inner wall of the movable groove 3 with a spring 6. The mounting frame 2 has symmetrically fixedly connected inclined rods 7 outside. Each inclined rod 7 has a slot 8 inside that cooperates with the inclined block 5. The ventilation chamber 1 has symmetrically arranged slots 9 inside that cooperate with the inclined rods 7, and the inclined end of each inclined block 5 is located inside the slot 9. Each limiting plate 4 has a sliding rod 10 fixedly connected to the side away from the inclined block 5. The other end of each sliding rod 10 extends to the outside of the ventilation chamber 1 and is fixedly connected to a pull ring 11. A pull rod 12 is provided between every two pull rings 11. Each pull rod 12 has a limiting head 13 fixedly connected to both ends.

[0027] In this embodiment, the filter plate 14 drives the fixing block 15 to be inserted into the mounting groove 16, and the first bolt 17 passes through the fixing block 15 and is threadedly connected to the mounting frame 2. Then, the sponge block 18 is inserted from the other side of the mounting frame 2 so that it contacts the filter plate 14. The mounting frame 2 drives the inclined rod 7 to be inserted into the slot 9. The inclined rod 7 squeezes the inclined block 5. The inclined block 5 drives the limiting plate 4 to squeeze the spring 6. After the inclined rod 7 is fully inserted into the slot 9, the limiting plate 4 is affected by the rebound force of the spring 6 and drives the inclined block 5 to reset and be inserted into the slot 8, thereby completing the quick connection between the ventilation chamber 1 and the mounting frame 2. At this time, the sponge block 18 is located between the ventilation chamber 1 and the mounting frame 2.

[0028] The pull rod 12 drives the pull ring 11 to move, which in turn drives the slide rod 10 to move. The slide rod 10 then drives the limiting plate 4 to move, and the limiting plate 4 then drives the inclined block 5 to disengage from the slot 8, allowing the mounting frame 2 to be removed and the sponge block 18 to be replaced. The filter plate 14 can be removed for replacement or cleaning by disengaging the first bolt 17.
