A toothbrush sterilizer is a device that uses ultraviolet light (such as UVC) irradiation, sometimes combined with photocatalysis, heating, and drying technologies, to kill bacteria and viruses on toothbrushes. Its main function is to sterilize and keep toothbrushes dry.
Most products feature a wall-mounted design, supporting drill-free installation. Some models have features such as intelligent sensor opening and closing, LED status display, and compatibility with electric toothbrushes. In actual use, its sterilization effect varies depending on the product and technology. It should be noted that ultraviolet light may not be able to completely penetrate the deep layers of the bristles, and the device itself may become a source of contamination if not cleaned properly.
