Description

Technical Field

[0001] The invention relates to the technical field of toothbrushes, in particular to a multifunctional electric toothbrush. Background Art

[0002] In daily life, people use toothbrushes to clean their mouths. However, manual toothbrushes usually do not clean teeth properly. Irregular manual operation strength and movements can cause bleeding gums and wear of tooth enamel. Electric toothbrushes are now available on the market, which include a handle and a toothbrush head. The rapid rotation or vibration of the motor core in the handle drives the toothbrush head to generate high-frequency vibrations, which are transmitted to the bristles of the toothbrush head for brushing. However, the toothbrush head can only vibrate irregularly and cannot brush the surface of the teeth in a directional manner like an ordinary toothbrush, resulting in poor cleaning effect on the teeth. Summary of the invention

[0005] By adopting the above scheme, the toothbrush head and the connecting seat can be an integral structure or a split structure, the transmission member can be an integral structure or a split assembly structure, the first transmission mechanism drives the transmission member to rotate reciprocatingly, thereby driving the reciprocating rotation of the toothbrush head, and the second transmission mechanism drives the transmission member to slide back and forth along the length direction of the handle body, thereby driving the directional reciprocating sliding of the toothbrush head. The first transmission mechanism and the second transmission mechanism can be driven by one driving source or by two driving sources respectively, which can not only realize the reciprocating rotation of the toothbrush head, but also realize the directional reciprocating sliding of the toothbrush head. The two brushing modes of the toothbrush head can be switched according to actual needs, and the teeth cleaning effect is better.
