[0014] As a further solution of the present invention: the reset unit includes a positioning rod and a spring;

[0015] The positioning rod is fixed to the inner wall of the cabinet and passes through the outer wall protrusion of the movable rod, and the positioning rod is used to provide a guide for the movement of the movable rod;

[0016] The two ends of the spring are respectively clamped on the inner wall of the cabinet and the protruding portion of the outer wall of the movable rod. The spring is used to provide the movable rod with elastic thrust in one direction at all times.

[0017] As a further solution of the present invention: the end of the movable rod close to the docking block is in an inclined state, and the inner side of the docking block matches the outer wall of the movable rod.

[0018] As a further solution of the present invention: the outer wall of the resisting block is in a hemispherical shape as a whole, and the moving track of the resisting block coincides with the position of the docking block.

[0019] As a further solution of the present invention: the inner wall of the cabinet is formed with a sliding groove for the movable rod, the transmission rod and the stop block to move axially, and the inner wall of the cabinet is also provided with a mounting groove for the lateral movement of the filter.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By setting a limiting mechanism, after the sealing door and the cabinet are closed, the outer wall of the sealing door will contact the end of the movable rod, thereby giving the limiting rod a thrust so that the other end of the limiting rod is aligned with the inner wall of the docking block, completing the limitation of the filter screen. When the sealing door is opened outward, the movable rod and the transmission rod move outward under the action of the spring, and the docking block is given an extrusion force by the block moving with the transmission rod, which synchronously drives the filter screen to move outward, thereby achieving the purpose of automatic separation of the filter screen, facilitating the installation and disassembly of the filter screen, and further improving work efficiency.
