High Efficiency Indoor Air Purifier

Abstract

The invention discloses a high-efficiency indoor air purifier, which comprises a shell. Double-layer side walls are arranged around the inner cavity of the shell. The height of the inner wall is lower than that of the outer wall; the lower end of the outer wall is provided with an air outlet. ; The center of the bottom of the shell cavity is provided with an exhaust fan, and a number of upright photocatalyst quartz glass sheets are evenly arranged around the bottom of the shell cavity around the exhaust fan; LED lamps that can emit ultraviolet light are fixedly installed around the bottom of the shell cavity; The invention is simple in structure and reasonable in design. Based on the principle of photocatalyst and the encapsulation technology of ultraviolet LED, it is designed and manufactured to save power and make no noise. The ultraviolet light does not leak out and harm the human body. It has several times the removal efficiency of harmful gases such as formaldehyde and benzene. Portable air purifier; can be used in living room, bedroom, bathroom, office, car, and can also be widely used in food display cabinets, hospitals, schools, shops, shopping malls and other public places, effectively inhibiting bacteria, viruses and mold.

Description

technical field [0001] The invention belongs to the technical field of air purification devices, and in particular relates to a high-efficiency indoor air purifier. Background technique [0002] Pollutants in the air can be roughly divided into three categories: particles, dust, harmful gases, ozone, bacteria, and mold viruses, etc.; due to the influence of coal burning and vehicle exhaust in outdoor air, the haze (PM2.5) is harmful, which is also When people are indoors, they try to close the doors and windows to prevent the inflow of bad air from the outside; the car closes the windows to prevent the exhaust gas from entering the car; but this also causes people to stay in the room where the air does not flow for a long time; Harmful gases such as benzene and ammonia are released for a long time, so the air pollution in the closed room is more than that in the outdoor, which has an impact on human health and even causes cancer. [0003] For this reason, there are various ...

[0002] Pollutants in the air can be roughly divided into three categories: particles, dust, harmful gases, ozone, bacteria, and mold viruses, etc.; due to the influence of coal burning and vehicle exhaust in outdoor air, the haze (PM2.5) is harmful, which is also When people are indoors, they try to close the doors and windows to prevent the inflow of bad air from the outside; the car closes the windows to prevent the exhaust gas from entering the car; but this also causes people to stay in the room where the air does not flow for a long time; Harmful gases such as benzene and ammonia are released for a long time, so the air pollution in the closed room is more than outdoors, which affects human health and even causes cancer

[0003] For this reason, there are various household air purifiers on the market, and the existing commercially available air purifiers are dazzling, but almost all filter the air with filter screen or negative ion technology; basically the filter screen technology is mainly to filter dust and particles, less in the room; but harmful gases such as formaldehyde and benzene cannot be filtered, and most products add activated carbon materials to absorb these gases; however, these activated carbons lose their effectiveness after the adsorption is saturated; in addition, negative ion technology uses high pressure The electrode is about four thousand volts (4KV), and it hits the air to generate negatively charged ions, which are used to absorb particles in the air and decompose harmful gases; but the process of generating negative ions also releases a lot of ozone. Just accumulate excess ozone; ozone will seriously endanger human health. The Ministry of Health stipulates that the safe concentration of ozone is 0.1PPM, which will cause poisoning. Therefore, an effective and energy-saving indoor space purifier is currently on the market. products in demand

Although ultraviolet light plus photocatalyst technology has long been used in air purification, the products on the market are almost only coated with photocatalyst or sprayed with photocatalyst, claiming that they can purify the air. Without corresponding ultraviolet light or only ordinary visible light, it is not effective Activate the purification physical mechanism; some use traditional ultraviolet lamps, which are prone to generate ozone and even emit C-type ultraviolet light that is harmful to the human body; of course, the ultraviolet LED and photocatalyst are only put together, and the relevant external conditions cannot be designed and integrated , such as air velocity, hygrometer light wave, illuminance, angle and reaction area, its air purification effect is negligible, so the technical effect of photocatalyst for air purification has not been broken through for a long time
