NOVELTY - The utility model claims a sterilizing electric toothbrush, it comprises brush handle and brush head, a brush handle and a brush head connected with the brush head is provided with a brush hair, a brush head provided with a ultraviolet sterilizing lamp. graphene, the graphene ultraviolet sterilizing lamp core comprises upper cover, lower cover, setting a light catalyze membrane layer and a upper cover and lower cover between, setting the LED light plate on lower cover, upper cover and lower cover set with a one way hole, the lighting side of the LED lamp board towards light and light catalyze membrane layer, the LED lamp board through the catalyze membrane layer emits light brush hair, light catalyze the film layer in turn comprises, the third dimension graphene, TiO2 nano thin film layer and nano-silver layer, a handle equipped with a power source, a power source and an LED lamp plate connected with, on the brush handle is provided with a power supply switch. The utility model of LED light plate and light through light catalyze membrane layer reflect on the brush hair of the brush hair to carry out sterilization, at the same time a high absorption of light catalyze membrane layer, the ray of light, an LED lamp plate and a peripheral absorbing brush hair at the same time too light to catalyze membrane layer of the bacteria by sterilize, enhance a sterilization effect for the toothbrush, and better protection of a cavity of people.
