How to use the toothbrush sterilizer?

Kuba helps the assistant answer your question about "". After brushing your teeth, put the toothbrush into the toothbrush sterilizer. The toothbrush sterilizer adopts cold cathode ultraviolet lamp tube, which can emit ultraviolet light with wavelength of 253.7nm, and is enhanced by emitting ultraviolet light wave with low mercury vapor pressure. There are mainly two emission lines, one is 253.7nm, which can make deoxyribonucleic acid (DNA), ribonucleic acid (RNA) and nucleoprotein in bacteria absorb ultraviolet rays. After the bacteria absorb ultraviolet rays, the DNA strand breaks, which leads to the cross-linking of nucleic acid and protein, killing the biological activity of nucleic acid and causing the death of bacteria. Toothbrush sterilizer can effectively kill bacteria in the range of 15-60 square meters, including Escherichia coli, mycobacterium tuberculosis, influenza virus, hepatitis B virus and more than 20 common bacterial viruses. The other is 185nm, which is used for high vacuum sterilization. Vacuum ultraviolet rays can ionize oxygen in the air to produce ozone, thus achieving the purpose of purifying the air. The dispersion of ozone can just make up for the shortcomings that ultraviolet rays can only travel in a straight line and disinfection has a dead angle. (Answer Editor: Bubble Hall)
