[0028] The air guide channel 11 of the embodiment can have the following shapes: as Figure 6 the straight channel, as Figure 7 the obliquely arranged oblique channel, and as Figure 8 the V-shaped channel structure with a curved middle part. The difference is that the length of the air guide channel 11 is extended to increase the surface area of the side wall of the air guide channel 11, so as to increase the effective area of the photocatalytic coating and improve the purification efficiency.

As Figure 5 shown, the catalytic light source 21 includes a plurality of and is arranged one-to-one with the light transmission hole 12. The light source module 2 of the embodiment is an LED lamp panel, and the catalytic light source 21 is an LED lamp bead.

[0031] In the above structure, the grating module 1 and the inner wall of the air guide channel 11 have a photocatalytic coating, and the light source module 2 provides a catalytic light source 21 for the photocatalytic coating. By connecting at least one light transmission hole 12 with each air guide channel 11, and arranging the catalytic light source 21 one-to-one with the light transmission hole 12, each LED lamp bead of the LED lamp panel is irradiated into the air guide channel 11, and the irradiation is close, which has the characteristics of high irradiation intensity and high efficiency, effectively solves the technical problem of light dead angle in the air guide channel 11, and the grating module 1 with a photocatalytic coating kills and decomposes odors.

[0032] Further, in the embodiment, as Figures 3 to 5 shown, the side wall of the air guide channel 11 has a plurality of convex parts 13. In the above structure, the convex parts 13 increase the surface area of the side wall of the air guide channel 11, so as to increase the effective area of the photocatalytic coating, thereby improving the purification efficiency.

In the above structure, the strip-shaped convex part 13 has the characteristics of easy manufacturing and simple structure on the basis of increasing the photocatalyst coating area.

After the air flow is sterilized by different factors in the above three stages, the air returns to the environment to achieve multi-stage air sterilization of the environment air. At the same time, the air after the multi-stage air sterilization is mixed with the environment air, and under the forced air supply of the external fan, the air is circulated back into the device again, and the air is repeatedly sterilized and purified by the device, and the air flow is circulated in this way, so that the number of microorganisms and odor molecules in the air is effectively reduced, and the excellent and efficient air purification function is achieved.
