[0022] Other objects and advantages of this utility model will become clear by explaining the preferred embodiments of the present application below.

[0023] Figure 1 This is a perspective view of a photocatalytic air purifier according to an embodiment of the present invention.

[0024] like Figure 1 As shown, the photocatalytic air purifier of this invention can be used for air purification and disinfection, and can also be installed in public spaces as a carrier for advertising. The photocatalytic air purifier of this invention includes a housing 110, and a controller 300 is provided on the left side surface of the housing 110. The controller 300 can control the start and stop of the device and set the operating parameters.

[0025] Figure 2 This is a perspective view of a photocatalytic air purifier according to one embodiment of the present invention. Figure 7 for Figure 2 A magnified view of part B in the image.

[0026] like Figure 2 and Figure 7As shown, a removable back plate 111 is provided on the rear side of the housing 110. By removing the back plate 111, the internal cavity 150 of the housing 110 can be opened (see...). Figure 4 A hook fastener 115 is installed on the back plate 111, and a hook-shaped body 116 is provided at the lower part of the hook fastener 115. The photocatalytic air purifier of this utility model can be installed on the wall by means of the mounting plate 200. Preferably, a groove 210 is provided on the upper side of the mounting plate 200, and the hook-shaped body 116 engages with the groove 210, so as to effectively fix the photocatalytic air purifier of this utility model in the left-right and front-back directions.

[0027] The mounting plate 200 includes a plate body 201. The end of the plate body 201 is bent 180° rearward and extends a distance towards the center of the mounting plate 200 to form a bent portion 220. The end of the plate body 201 has a first fixing hole 231, and the bent portion 220 has a second fixing hole 232 corresponding to the position of the first fixing hole 231. The inner diameter of the first fixing hole 231 is larger than the inner diameter of the second fixing hole 232. With this structure, the fastening screw passes through the second fixing hole 232, and the head of the fastening screw can be recessed into the space between the plate body 201 and the bent portion 220, avoiding interference between the head of the fastening screw and the hook fastener 115. The bent portion 220 improves the rigidity and strength of the mounting plate 200 and creates an installation space between the wall surface and the mounting plate 200 to accommodate the hook-shaped body 116.

[0028] Figure 3 This is a front view of a photocatalytic air purifier according to an embodiment of the present invention. Figure 4 for Figure 3 AA section view in the image.

[0029] like Figure 3 and Figure 4 As shown, an internal cavity 150 is formed between the housing 110 and the back plate 111. An air inlet 120 is provided at the bottom of the housing 110, and an air outlet 130 is provided at the top of the housing 110. An internal cavity 150 for airflow is formed between the air inlet 120 and the air outlet 130.

[0030] In this invention, to reduce the size of the equipment while providing sufficient installation space for the fan 160, a partition 140 is provided in the internal cavity 150. The partition 140 is approximately located in the middle of the internal cavity 150 and extends in the left-right direction. The partition 140 is spaced apart from the front panel and back panel 111 of the housing 110, dividing the internal cavity 150 into a first cavity 151 located behind the partition 140 and a second cavity 152 located in front of the partition 140. The first cavity 151 communicates with the air inlet 120, and the second cavity 152 communicates with the air outlet 130.

[0031] To reduce wind resistance, the partition 140 also includes a body portion 141, a first extension portion 142, and a second extension portion 143. The body portion 141 is arranged longitudinally. The lower end of the first extension portion 142 is connected to the body portion 141, and the upper end of the first extension portion 142 is inclined upward and extends rearward. The upper end of the second extension portion 143 is connected to the body portion 141, and the lower end of the second extension portion 143 is inclined downward and extends forward. The body portion 141 is provided with an air guide hole 144 that extends through it in the front-rear direction. The air guide hole 144 is used to connect the first cavity 151 and the second cavity 152. A cylindrical air guide ring 145 is provided on the air guide hole 144.

[0032] Inside the second cavity 152, a fan 160 is positioned opposite the air guide hole 144. The fan 160 is used to generate airflow from the first cavity 151 to the second cavity 152. Inside the second cavity 152, near the front wall of the housing 110, a motor mounting plate 114 is provided for fixing the motor of the fan 160.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, a receiving portion 170 is provided at the bottom of the first cavity 151, near the air inlet 120. The receiving portion 170 has an inflow end 174 on its lower side and an outflow end 175 on its upper side. The cross-sectional area of ​​the orifice of the inflow end 174 is larger than that of the orifice of the outflow end 175. A receiving cavity 173 is formed between the inflow end 174 and the outflow end 175. A medium-efficiency filter 172 and a pre-filter 171 are installed sequentially from top to bottom in the receiving cavity 173. When installing or replacing the filters, the medium-efficiency filter 172 is first placed into the receiving cavity 173 through the inflow end 174, and then the pre-filter 171 is placed into the receiving cavity 173 through the inflow end 174.

[0035] In this embodiment, a photocatalyst module 180 is installed on the top of the second cavity 152. The photocatalyst module 180 can decompose harmful gases, sterilize and disinfect, and remove odors. The aforementioned photocatalyst module 180 can be, for example, the photocatalyst module disclosed by the applicant of this utility model in Chinese Utility Model Patent Publication No. CN212108814U, but is not limited thereto.
