[0004] Double-repellent membrane: It has the characteristics of hydrophobicity and oleophobicity, which can effectively prevent the accumulation of oily aerosols and ultrafine particles on the surface of the membrane material, thereby improving the filtration efficiency and stability;

[0005] Photocatalyst aluminum-based filter: Photocatalyst is a general term for semiconductor materials with photocatalytic function, represented by nano-scale titanium dioxide. Under the action of ultraviolet light and visible light, it produces strong catalytic degradation function, which can effectively degrade toxic and harmful gases in the air, effectively kill a variety of bacteria, and decompose and harmlessly treat toxins released by bacteria or fungi.

[0013] Preferably, a mounting seat is fixedly arranged on the top of the air distribution frame, and a positioning seat covers the surface of the mounting seat and is fixed by bolts, and a sealing gasket is used to seal the positioning seat and the mounting seat.

At the same time, the multiple groups of air distribution holes are arranged opposite to the filter membrane, and the cross-section of the air distribution holes is an isosceles trapezoidal structure.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
