[0033] The following further elaborates on the embodiments of the present utility model with reference to the accompanying drawings.

[0034] According to some embodiments of the present utility model, referring to Figure 1 and Figure 2 , the wall-mounted air purifier includes a housing 100, a fan assembly 200, and a purification assembly 300.

The fan assembly 200 is disposed inside the housing 100, the air inlet end of the fan assembly 200 faces the air inlet 120, and the air outlet end of the fan assembly 200 faces the air outlet 110. The purification assembly 300 is disposed inside the housing 100, the purification assembly 300 is located between the air outlet 110 and the air outlet end of the fan assembly 200, the purification assembly 300 includes a UV lamp 310 and a photocatalyst structure 320, the UV lamp 310 irradiates the photocatalyst structure 320 to cause the photocatalyst structure 320 to release disinfection factors, and the fan assembly 200 can drive the gas to pass through the purification assembly 300 and be discharged from the air outlet 110..

[0035] The surface of the photocatalyst structure 320 has a photocatalyst coating, which is a nano-level titanium dioxide active material. It is coated on the surface of the substrate and forms a thin film after drying. Under the action of light, it has a strong catalytic degradation function, can effectively degrade toxic and harmful gases in the air, can effectively kill a variety of bacteria, with an antibacterial rate as high as 99.99%, and can decompose and detoxify the toxins released by bacteria or fungi; at the same time, it also has functions such as deodorization and anti-fouling.

[0036] Under light irradiation, the photocatalyst can absorb light energy equivalent to that below the bandgap energy, causing excitation on its surface to generate electrons (e-) and holes (h+). These electrons and holes have strong reduction and oxidation capabilities, can react with water or dissolved oxygen to generate hydroxyl radicals (·OH) and superoxide anions (·O) disinfection factors. The oxidation energy of these holes and hydroxyl radicals is greater than 120 kcal / mol, with strong oxidation ability, and can almost cut and decompose the chemical bonds of all organic molecule components. Therefore, various harmful chemical substances and odorous substances can be decomposed or detoxified, achieving the effects of purifying the air, anti-fouling, and deodorization.

[0037] During the operation of the wall-mounted air purifier, when the UV lamp 310 irradiates the photocatalyst structure 320, disinfection factors are generated. The fan assembly 200 draws external air into the housing 100 through the air outlet holes 110. When the air passes through the photocatalyst structure 320, it can react with the disinfection factors to purify the air, and the purified air is then discharged from the air outlet holes 110. At the same time, the disinfection factors on the photocatalyst structure 320 can also be blown out through the air inlet holes 120, so that the disinfection factors enter the external environment to purify the air and improve the purification efficiency. Moreover, the light of the UV lamp 310 also has the effect of disinfection and sterilization.

[0038] According to some embodiments of the present invention, referring to Figure 2 , the fan assembly 200 includes a volute 210, an impeller 220 and a driving component 230. The volute 210 is fixedly installed inside the housing 100. The impeller 220 is arranged inside the volute 210 and is rotatably connected to the volute 210.

The photocatalyst structure 320 is fixedly installed on the mounting bracket 330. The two photocatalyst structures 320 are respectively located on the upper and lower sides of the UV lamp 310. The irradiation of the UV lamp 310 can cause the two photocatalyst structures 320 located on the upper and lower sides of the UV lamp 310 to release disinfection factors. The air in the housing 100 passes through the two photocatalyst structures 320 in sequence from bottom to top, so as to complete the purification and disinfection of the air.
