How ultraviolet rays kill bacteria?
Ultraviolet sterilization is a pure physical function. When the ultraviolet ray is irradiated at 270-280nm wavelength, the RNA and DNA of bacteria, mites and other microorganisms will be broken, which will make them lose the ability of reproduction and survival, so as to achieve the purpose of sterilization.
When the Sterilizing lamp is working, if humans or pets break into the room by mistake,the automatic protection device will be started and the sterilization lamp will turn off. When the sterilizing lamp is working, upon detection of any human within 5m of the device, the beep reminder will ring and all the indicator lights will flash,,then the lamp will switch off. Upon detection of humans leaving, the timing will continue for about 30s.
