Hand-held ultraviolet ray disinfection apparatus

Abstract

The invention provides a hand-held ultraviolet ray disinfection apparatus. The hand-held ultraviolet ray disinfection apparatus comprises an upper part reflection ultraviolet ray housing (1), a switch (2), a lower part quartz glass sleeve (3), a 254mm ultraviolet sleeve (4), a boost power supply system (5) and a high-capacity chargeable cell (6). The hand-held ultraviolet ray disinfection apparatus is light, small and portable and can be used anytime and anywhere. When the disinfection apparatus is used, the switch is turned on, the high-capacity chargeable cell starts power supply, and supplies power for the 254mm ultraviolet lamp tube after boost processing, high-energy ultraviolet rays are emitted, the upper part of the housing can reflect the ultraviolet rays, the ultraviolet rays are utilized fully and human bodies are prevented from direct irradiation, the lower part employs the high-transmittance quartz glass sleeve, and the ultraviolet ray passing rate can reach more than 90%. The high-energy ultraviolet rays penetrate cell membranes of bacteria and viruses and damages nucleic acids (DNA), thus cells lose a reproductive capacity and the effect of rapid sterilization is achieved.

Description

technical field [0001] The present invention relates to a hand-held disinfection and sterilization equipment based on 254nm wavelength ultraviolet rays, in particular to a hand-held disinfection and sterilization equipment capable of penetrating bacteria and viruses and damaging their DNA. Background technique [0002] We live in a world full of bacteria and viruses. We are in contact with bacteria and viruses all the time. In most cases, our body's three lines of defense (skin and mucous membranes, phagocytic lysozyme, and immune organs) will block their invasion. So we don't feel sick, but once the bacteria successfully break through the three lines of defense, our body will get sick, such as a cold. Although with the improvement of medical level, more and more diseases can be cured now, and serious diseases such as tuberculosis that were difficult to cure decades ago are no longer a problem today, but in many cases, due to the similarity of disease symptoms, if you do not...

Problems solved by technology

[0004] Although UV surface sterilization devices are widely used in food, medicine, health care, biology, beverage, agriculture and other fields, due to the professionalism and non-portability of ultraviolet sterilizers, sterilizers have not affected the lives of ordinary people, and people do not Those who have not enjoyed the safe living environment created by ultraviolet rays, on a larger scale, there are not a few E. coli in the tableware of major hotels that exceed the standard, and this brings diarrhea and gastrointestinal infections, which seriously endanger their health; Few people have acne or other skin diseases on their faces that affect their appearance, and this is ultimately caused by bacteria and mites on the bedding; such things have affected our lives
