[0024] In this embodiment, the gas is introduced into the box body 2 through the air delivery pipe 10, and the gas is sequentially filtered and sterilized by the filter screen 3, the HEPA filter screen 4, the sterilization layer 5 and the zeolite molecular sieve screen 6. By controlling the operation of the motor 71, the lead screw 73 can be driven to rotate, and the lead screw 73 will drive the cleaning push plate 74 to move downward. The brush 75 on its side can clean the mesh holes of the filter screen 3, clean the blocked mesh holes of the filter screen 3, avoid the blockage of the mesh holes, and enhance the subsequent filtering effect.

[0025] Among them, the filter screen 3 conducts preliminary filtering work on the gas. Then, the HEPA filter screen 4 removes fine particles in the gas.

Finally, the zeolite molecular sieve screen 6 can still maintain a strong adsorption capacity for some polar molecules at higher temperatures and lower partial pressures. The gas generated in the purification device is purified by a multi-stage filtering method, effectively improving the gas purification effect.
