[0024] Purification cabin 4 is a prism, one end of purification cabin 4 is provided with fixed platform 42, the other end of purification cabin 4 is connected with purification pipe 41, the other end of purification pipe 41 is also provided with purification cabin 4, both ends of purification pipe 41 are attached to the end face of small size of purification cabin 4, and fixed platform 42 is attached to the large size end of purification cabin 4.

[0025] Specifically, activated carbon is stored in the inside of purification cabin 4 and purification pipe 41, the air intake of one end of purification cabin 4 is increased by the large size, the air intake pressure is increased by purification pipe 41, the processing effect of activated carbon in the inside of one end of purification cabin 4 and purification pipe 41 on air is enhanced, and the air is discharged by pressure relief from the other end of purification pipe 41, to complete the purification treatment of activated carbon on air.

[0026] Purification pipe 41 is connected with the purification cabin 4 at both ends, the other end of purification cabin 4 is connected with fixed platform 42, air permeable membrane 43 is arranged in the inside of fixed platform 42, one end of air permeable membrane 43 is located on the side where purification pipe 41 is connected with fixed platform 42, and the thickness of air permeable membrane 43 is half of the thickness of fixed platform 42.

[0027] Specifically, by the air permeable membrane 43, when the air enters the purification cabin 4 from the fixed platform 42, the activated carbon inside the purification cabin 4 and the purification pipe 41 is simultaneously blocked, avoiding the air carrying the activated carbon out, affecting the air purification effect.

[0028] One side of the fixed platform 42 is connected with the inner side wall of the fixed layer 2, and the end face of one side of the fixed platform 42 is flush with the end face of one side of the fixed layer 2. The plurality of fixed platforms 42 are connected with each other.

[0029] Specifically, the purification cabin 4 is fixed with each other through the plurality of fixed platforms 42, and is fixed inside the fixed layer 2 through the fixed platform 42.

[0030] The outer diameter shape of the filter screen frame 1, the fixed layer 2 and the purification layer 3 is the same, the inner diameter size of the purification layer 3 is larger than the inner diameter size of the fixed layer 2, and the inside of the filter screen frame 1 is provided with the filter screen 11.
