Abstract
Description
Technical Field
[0001] The invention relates to the field of air purifiers, and in particular to an environmentally friendly total reflection photocatalyst air purifier. Background Art
[0002] Photocatalyst air purification is the use of photocatalyst technology under certain circumstances. After being irradiated with a certain energy level of light, the generated hydroxyl free radicals with strong oxidation ability can quickly decompose toxic and harmful gases, effectively kill various bacteria, molds, viruses, remove various odors, smoke, absorb dust, etc., and can quickly and effectively improve indoor air quality. Through photocatalyst technology, the air in people's smart home environment can be purified, improving people's living comfort.
[0003] In the existing photocatalyst air purification equipment, the ultraviolet light is only irradiated on one side of the photocatalyst net, so that the side of the photocatalyst net can produce hydroxyl free radicals for air purification, which leads to limited air purification effect and reduces the practicality of the existing photocatalyst net air purification efficiency;
[0004] Secondly, the existing photocatalyst air purifiers also have multiple photocatalyst filters arranged in a grid, and then irradiated with ultraviolet light on the top, and a reflector is added to one side of the filter. Because the irradiation angle is side light, the light beam reflected by the reflector is still irradiated from the side, which leads to a very low reaction efficiency;
[0005] Secondly, it is very difficult to replace the lamps of most photocatalyst air purifiers on the market. The whole machine needs to be repaired, and there is no design consideration for quick lamp replacement.
[0006] Finally, most of the existing air purification equipment filters the air through high-efficiency filters such as activated carbon or HEPA. After these filter materials enter the decline period, they are also prone to breed bacteria. If the filter materials are not replaced on time, secondary pollution will occur and endanger health. At the same time, the cost of high-efficiency filter materials is very high, and the disposal of discarded filter materials is not environmentally friendly. Summary of the invention
[0007] The purpose of the present invention is to provide an environmentally friendly total reflection photocatalyst air purifier to solve the above technical problems.

[0015] Preferably, the thickness of the reflector is 0.3 mm.
[0016] Preferably, the chassis, the photocatalyst reaction net and the reflective cover are in the shape of a cuboid, a barrel or other polygonal shapes.
[0017] Preferably, the wavelength of the ultraviolet lamp is 200-400nm, and the minimum power is 2W; the wavelength below 200nm will produce ozone, and a large amount of ozone will harm human health. The present invention avoids the generation of ozone; because the ultraviolet light beam is reflected multiple times in the closed reflective chamber, the utilization rate of light is greatly improved, thereby reducing the power of the ultraviolet lamp, and a minimum ultraviolet lamp of 2W can be selected to achieve a total power of no more than 5W. At the same time, the purifier has no consumables and is a truly energy-saving and environmentally friendly design product.
[0018] Preferably, both the top and the bottom of the chassis may be coated with a reflective coating to increase the reflection path of the light.
[0019] Preferably, the reflective cover can be integrated with the chassis, and the reflection is also a reflection without dead angles, but the angle of the reflected light will not change because the reflective cover is fixed, which can reduce the production cost.

[0036] In the specific implementation process, Figure 1-5 As shown, the thickness of the reflector 7 is 0.3 mm.
[0037] In the specific implementation process, Figure 1-5 As shown, the chassis 1, the photocatalyst reaction net 10 and the reflective cover 7 are in the shape of a rectangular parallelepiped, a barrel or other polygonal shapes.
[0038] In the specific implementation process, Figure 1-5 As shown, the wavelength of the ultraviolet lamp 11 is 200-400nm, and the minimum power is 2W; the wavelength below 200nm will produce ozone, and a large amount of ozone will harm human health. The present invention avoids the generation of ozone; because the ultraviolet light beam is reflected multiple times in the closed reflective chamber, the utilization rate of light is greatly improved, thereby reducing the power of the ultraviolet lamp, and a minimum ultraviolet lamp 11 of 2W can be selected, so that the power of the whole machine does not exceed 5W.

[0039] In the specific implementation process, Figure 1-5 As shown, the fan 3 can also be set at the bottom of the chassis 1, blowing air from the top of the chassis 1 to the inside, the air enters through the air outlet 2, and after being processed, it is finally discharged through the air inlet 9.
[0040] The working principle of the present invention is as follows:
[0041] During use, indoor air first enters the inside of the chassis 1 through the air inlet 9 on the base 8. The air inlet 9 adopts an oblique air inlet design, which can allow the air passing through the air inlet 9 to form a vortex turbulence and rise. When the air vortex turbulence passes through the reflector 7, the reflector 7 will shake irregularly, and the spoiler 72 on the outside of the reflector 7 will shake to a certain extent. At this time, the light generated by the ultraviolet lamp tube 11 passes through the photocatalyst reaction net 10 and irradiates the reflector 7. Since the reflector 7 is provided with a reflective coating 73, at this time, under the action of the reflective coating 73, the ultraviolet light is reflected at multiple angles to the photocatalyst reaction net 10. Due to the mechanism of irregular shaking of the reflector 7 caused by aerodynamics, the reflected light will generate multiple reflections in the reflector 7, thereby greatly improving the utilization rate of the ultraviolet light beam. The filtered air is finally discharged through the air outlet 2 to achieve air purification.
[0042] During use, when the user wants to repair or replace the ultraviolet lamp 11, since the chassis base can be opened by screwing, the user can easily unscrew the ultraviolet lamp and replace it. After the ultraviolet lamp fails, a low-cost lamp replacement maintenance function is achieved.
[0043] The photocatalyst reaction net 4 is exposed to multiple and multi-angle ultraviolet light irradiation, and the absorption of light energy inside it stimulates the generation of electron-hole pairs, i.e., photogenerated carriers, which then quickly migrate to its surface and activate the adsorbed oxygen and moisture to generate active free hydroxyl radicals (-OH) and active oxygen (-O). When pollutants and bacteria adsorb on its surface, a chain degradation reaction occurs.
[0044] Compared with the related art, the environmentally friendly full-reflection photocatalyst air purifier provided by the present invention has the following beneficial effects:
[0045] The present invention provides an environmentally friendly fully reflective photocatalyst air purifier. First, the reflective cover 7 is triggered by aerodynamic force to vibrate, so that the ultraviolet light beam is reflected at multiple angles for many times, thereby greatly improving the utilization rate of light, and at the same time allowing the photocatalyst reaction net 10 to receive light without dead angles, ultimately improving the reaction efficiency of the photocatalyst. At the same time, because there is no dead angle in the illumination angle, due to environmental application requirements, the present invention includes at least one layer of photocatalytic coal reaction net 10 and at least one ultraviolet lamp tube 11 combination. The photocatalyst net can be made of appropriate thickness to accommodate more photocatalysts and improve the reaction efficiency. In addition, the fully reflective reflective cover 7 is added to form a more efficient photocatalyst air purifier. Secondly, the base 8 can be screwed and disassembled, and the ultraviolet lamp tube 11 can be conveniently replaced, which is convenient for users to reduce the cost of maintaining the equipment and extend the service life of the equipment. Finally, the present invention has no filter material, and there is no cost for replacing the filter material and the possibility of secondary pollution. It is a truly environmentally friendly and efficient air purifier.
