[0023] like Figure 1-Figure 3As shown, the support assembly 1 includes a base plate 101, a plurality of vertical rods 102 are fixed on the upper surface of the base plate 101, a bearing plate 103 is fixedly connected to the top of the plurality of vertical rods 102, an annular plate 104 is fixed to the upper surface of the bearing plate 103 and located on the outside of the dustproof assembly 3, the bottom end of the outer shell 2 is clamped on the outside of the annular plate 104, and a locking bolt 17 is penetrated and threadedly connected to the side wall of the bottom end of the outer shell 2.

[0024] When assembling the device, the outer shell 2 is directly sleeved on the surface of the annular plate 104, the outer shell 2 is supported by the supporting plate 103, and then the locking bolts 17 are tightened to fix the outer shell 2. When the outer shell 2 and the supporting assembly 1 need to be disassembled, the locking bolts 17 are loosened and the outer shell 2 is directly lifted from the surface of the supporting plate 103.

[0025] like Figure 1-Figure 3 As shown, the dustproof assembly 3 includes an annular net 31 fixed to the upper surface of the bearing plate 103 , and a top frame 32 is fixedly connected to the top of the annular net 31 .

[0026] The annular net 31 is made of a metal net, which can support the top frame 32 , and when the external air passes through the air inlet 201 and enters the interior of the housing 2 , the annular net 31 can block large particles of dust and impurities.

[0027] like Figure 1-Figure 3 As shown, the first formaldehyde removal component 4 includes an annular frame 41, and a partition net 42 is fixedly connected to the top and bottom ends of the annular frame 41. The annular frame 41 and the partition net 42 are filled with activated carbon. The lower surface of the annular frame 41 is fitted with the upper surface of the top frame 32. A first support ring 5 is fixed to the inner wall of the outer shell 2, and the upper surface of the annular frame 41 is fitted with the lower surface of the first support ring 5.

[0028] When external air enters the shell 2 from the air inlet 201 and flows upward, the activated carbon can absorb a part of the formaldehyde, and when the shell 2 is fixed on the top of the support assembly 1, the top frame 32 and the first support ring 5 can just squeeze and fix the first formaldehyde removal assembly 4. When the shell 2 is lifted from the surface of the supporting plate 103, the first formaldehyde removal assembly 4 is located on the surface of the top frame 32, thereby making the installation and disassembly of the first formaldehyde removal assembly 4 simple and convenient.

[0029] like Figure 2 As shown, the fan assembly includes a plurality of cross bars 6 fixed to the inner wall of the housing 2, the other ends of the plurality of cross bars 6 are commonly fixedly connected to a motor 7, and the driving end of the motor 7 is fixedly connected to a fan blade 8.

[0030] By driving the fan blades 8 to rotate through the motor 7 , external air can be sucked into the interior of the housing 2 from the air inlet 201 , then flow upward along the interior of the housing 2 , and finally blown out from the top of the housing 2 .

[0031] like Figure 1-Figure 2As shown, the motor 7 and the ultraviolet lamp 11 are connected to the power module 10 through wires, and a switch button is provided on one side of the power module 10 outside the housing 2.

The top cover 14 is fixed by a magnet so that the top cover 14 can be directly removed from the top of the housing 2. After the top cover 14 is removed, the photocatalyst 13 inside the housing 2 can be taken out, which is convenient for cleaning and replacing the photocatalyst 13.

[0035] Working principle: After starting the device, the motor 7 drives the fan blades 8 to rotate, and at the same time, the ultraviolet lamp 11 lights up, and the outside air will enter the shell 2 from a circle of air inlets 201 on the side wall of the shell 2 to achieve the suction of reverse air in the room. After the air enters the shell 2, the formaldehyde in the air is first adsorbed by the activated carbon of the first formaldehyde removal component 4, and the photocatalyst 13 undergoes a photochemical reaction after being irradiated by the ultraviolet lamp 11 to decompose various organic compounds and some inorganic substances, thereby further removing formaldehyde, and finally the clean air is discharged from the top of the shell 2. During the working process, the sound-absorbing cotton 9 will absorb part of the noise generated by the motor 7 driving the fan blades 8 to rotate, reducing the noise of the device when it is working. If it is necessary to clean and replace the dustproof component 3 and the first formaldehyde removal component 4, loosen the locking bolt 17, and then lift the shell 2 from the top of the support component 1 through the handle 16. At this time, the dustproof component 3 is exposed, and the first formaldehyde removal component 4 is located on the top of the dustproof component 3. When the photocatalyst 13 needs to be cleaned or replaced, the top cover 14 is removed from the top of the housing 2 , and then the photocatalyst 13 is directly taken out from the top of the housing 2 .
