Background
Along with the improvement of living standard and living quality of people, people pay more and more attention to health and hygiene, however, people inevitably contact with environments such as bacteria and viruses in life. Ultraviolet sterilization is to use physical method to generate ultraviolet radiation with different wave bands to damage and destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in organism cells of microorganisms (pathogens such as bacteria, viruses, spores and the like), so as to cause death of growing cells and/or death of regenerative cells, change biological activity, and prevent microorganisms from replicating and propagating to achieve the purpose of disinfection and sterilization. Through tests, the effective wavelength range of ultraviolet sterilization can be divided into four different wave bands: UVA (400-320 nm), UVB (320-280 nm), UVC (280-200 nm) and vacuum ultraviolet (200-10 nm). Wherein only UVA and part of UVB that are able to reach the earth's surface through the ozone protective layer and cloud layer. In terms of sterilization rate, UVC is within the microbial absorption range and can be sterilized within 1 second by destroying the DNA structure of the microbes, whereas UVA and UVB are outside the microbial absorption range and sterilization rate is slow, often requiring several hours to sterilize. Ultraviolet rays can sterilize, but radiation of ultraviolet rays for a long time can also cause adverse effects on human health.
The ultraviolet rays of the existing commercial ultraviolet sterilizer products are emitted by quartz mercury lamps. The principle is that the mercury vapor with lower pressure is activated to emit ultraviolet light, and the two main emission lines are: one is 253.7nm wavelength; the other is 185nm wavelength. However, mercury lamps contain highly toxic mercury, and the product has been forced to be eliminated worldwide for a limited period of time according to international agreements, such as the regulations on hazardous substances, and if mercury leaks from the equipment, it can cause significant harm to the human body and the environment. Meanwhile, the ultraviolet ray with the wavelength of 185nm can generate ozone, thus being harmful to human health and environment; and the structure of the existing ultraviolet sterilizer is complex, which is not beneficial to the replacement, maintenance and use of the accessories of the user.
