Electric toothbrush utilizing optical fiber to guide light and sterilize

Abstract

The utility model relates to the technical field of electric toothbrushes, in particular to an electric toothbrush utilizing optical fiber light guide sterilization, which comprises a toothbrush handle portion, a toothbrush head portion is mounted at the top end of the toothbrush handle portion, and an optical fiber light guide sterilization mechanism is mounted in the toothbrush head portion. The optical fiber light guide sterilization mechanism is composed of an optical fiber wrapping layer, an optical fiber inner core, a gasket and an LED lamp bead. The toothbrush handle part is composed of a handle, a support, a PCBA board, a battery and a motor, the support is fixed in the handle, the PCBA board is fixed on the surface of the support, and the battery is installed on the surface, away from the PCBA board, of the support. By arranging the optical fiber light guide sterilization mechanism, when the optical fiber light guide sterilization mechanism is implemented, the ultraviolet LED lamp bead is removed from the brush head and arranged on the body or the handle, ultraviolet light is refracted and guided into an oral cavity in a light guide mode, and the phenomenon that the LED lamp bead enters the oral cavity is avoided; ultraviolet light is transmitted into the oral cavity through the optical fiber, so that a non-contact sterilization effect is achieved.
