Abstract
This application provides an oscillating toothbrush, including a brush head, a brush handle, an oscillating base mounted on the brush handle, and an oscillating rod that connects the brush head to the oscillating base, and the oscillating base includes 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, with the first direction being perpendicular to the second direction. In the present application, the oscillating base is arranged to include 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 the brush head is subjected to an external force, the oscillating rod may drive the first hinge base to oscillate on the brush handle in the first direction. In one embodiment, the oscillating rod oscillates on the fixing shaft in the second direction to further drive the second hinge base to oscillate on the brush handle in the second direction. Therefore, with the oscillation of the first hinge base and the second hinge base, the brush head is allowed to oscillate at multiple angles under external forces in different directions, to improve the comfort of toothbrushing.
