1. Adopt cold cathode germicidal UV germicidal lamp as a core component may issue a wavelength of 254nm ozone and UV which will kill bacteria viruses and other microorganisms; the main role is to destroy the microbial nucleic acids DNA ribonucleic acid (RNA) to immediate death or loss of reproductive capacity resulting in the death of bacteria and viruses. Ozone molecule is very unstable can decompose to produce strong single-atom oxidation oxygen (O) and hydroxyl (OH) be quickly integrated into the cell wall destroy the internal structure of bacteria viruses and other microorganisms and play a vital role in killing a variety of pathogenic microorganisms. 2. Strong ultraviolet rays can effectively kill 99.9% of the bacteria and viruses. 3. Can effectively reduce the stomatitis diseases such as periodontitis gingivitis sore throat and bad breath. 4. With a toothbrush tray can be removed cleaned and kill bacteria. 5. Convenient to use close the cover for about 5 minutes' auto sterilization till automatical shutdown. 6.
