Description

UV LED Portable Surface Sterilizer

technical field

The utility model relates to the technical field of sterilization and disinfection devices, in particular to a UV LED portable surface sterilizer.

Background technique

In the current environment we live in, whether it is in the air, water, food or other objects that we often come into contact with, there are inevitably various bacteria and viruses. These viruses enter the human body through various channels, destroy the human body, cause diseases, and endanger human health.

Therefore, various methods to destroy bacteria and viruses have been developed. At present, a method of eliminating these bacteria mainly relies on chemical disinfection preparations to carry out by spraying, cleaning and other methods. However, the chemical method has secondary pollution, cannot effectively remove the peculiar smell, and the cost is not low, so the effect is not ideal. Another commonly used method of sterilization and disinfection is to use ultraviolet light to sterilize and disinfect. As we all know, sunlight contains ultraviolet rays. People often use sunlight to expose clothes, bedding, etc. to kill mites and bacteria. There is also a kind of artificial ultraviolet sterilizing lamp. The traditional sterilizing and disinfecting ultraviolet light source is a low-pressure mercury lamp. The dominant wavelength is usually 253.7nm. Due to the large size, high voltage requirements, fragility, and high heat generation of low-pressure mercury lamps, the application of low-pressure mercury lamps is limited in portable, small, battery-powered, temperature-sensitive, and outdoor applications.

After research, it is found that some wavelengths of ultraviolet rays can destroy the DNA structure of bacteria or viruses, and play a role in disinfection and sterilization. The ultraviolet light emitted by UV-LEDs with a wavelength of 250nm to 300nm acts on the nucleic acid of microorganisms (deoxyribonucleic acid DNA, ribonucleic acid (RNA), etc., can destroy the chemical bonds of molecular chains, thereby destroying or modifying the chemical structure of cells, and has a good sterilization and disinfection effect. As far as the light source of ultraviolet sterilization and disinfection is concerned, it is a good supplement to the low-pressure mercury lamps commonly used at present. and perfect.

In view of this, the utility model is proposed.
