[0016] The utility model is a mechanized transformation carried out on the basis of the original purification box, mainly improving the door lock mechanism and the filter pressing mechanism, reducing the power input points, and adding a mechanical interface suitable for automatic operation, making it more suitable for automatic operation.

[0017] The original box door was compressed and sealed by tightening the four fasteners at the four corners. It has now been changed to a connecting rod and latch structure, and the overall compression seal can be achieved by inputting torque through the hexagonal head at the center point.

[0018] When replacing the filter, the original box door needs to be removed as a whole. Now it has been changed to a drawer-type structure, and the box door can be pulled out horizontally without being removed.

[0019] The original clamping mechanism operated two rocker arms to drive the cam to rotate, so that the lifting tray rose to clamp the filter. Now it has been changed to a parallelogram connecting rod mechanism. The lifting tray rises as the box door is pushed in, realizing the compression and sealing of the filter without separate operation. BRIEF DESCRIPTION OF THE DRAWINGS
