Title:
VIBRATING TOOTHBRUSH
Document Type and Number:
WIPO Patent Application WO/2023/020000
Kind Code:
A1
Abstract:
The present application provides a vibrating toothbrush, comprising a brush head, a brush handle, a vibration base mounted on the brush handle, and a vibration rod for connecting the brush head to the vibration base. The vibration base comprises a first hinge base hinged to the brush handle in a first direction, a second hinge base hinged to the brush handle in a second direction, and a fixing shaft mounted on the first hinge base in the second direction, the first direction being perpendicular to the second direction. In the present application, the vibration base is configured to be the first hinge base hinged to the brush handle in the first direction, and the second hinge base hinged to the brush handle in the second direction. When external force acts on the brush head, the vibration rod can drive the first hinge base to vibrate on the brush handle in the first direction; or, the vibration rod vibrates on the fixing shaft in the second direction to drive the second hinge base to vibrate on the brush handle in the second direction. Therefore, by means of the vibration of the first hinge base and the second hinge base, the brush head can vibrate at multiple angles under the action of external force in different directions, thereby improving the comfort of tooth brushing.
