The opposite ends of the two sets of guard plates 25 are movably connected to a connector 26.

[0020] By adopting the above technical solution, the protective plate 25 is connected by the connector 26 and the damper 24 is used to form a slight elastic effect, thereby providing impact protection for the adsorption tower body 11 and effectively protecting the adsorption tower body 11.

[0021] A PCL controller 27 is fixedly installed on the top surface of the collection box 13.

[0022] By adopting the above technical solution, it is convenient to adjust the device operating parameters on the control panel 1.

However, when the particulate filter element 16 and the humidity filter element 17 are blocked due to long-term filtration, resulting in a decrease in performance, the adjusting nut 22 is removed from the stud 21, and then the movable plate 18 is pulled to move. The movable plate 18 drives the spring 19 to stretch, which also drives the L-shaped rod 20 to disengage from the cover plate 14, thereby pulling the cover plate 14 to move the connecting frame. 15 is removed from the connecting tube 12, facilitating the cleaning and maintenance of the particulate filter 16 and the humidity filter 17. After cleaning, the connecting frame 15 is inserted into the connecting tube 12. The spring 19 pulls the movable plate 18 and the L-shaped rod 20 to move and position the cover plate 14.
