Abstract:
Provided are a toothbrush assembly and an electric toothbrush. The toothbrush assembly comprises a brush handle, a brush head and an elastic member, wherein the brush handle is provided with a mounting slot at an end portion thereof; the brush head comprises a brush head seat; the brush head seat is at least partially received inside the mounting slot; the elastic member elastically abuts against an outer side wall of the brush head seat and an inner side wall of the mounting slot, such that the brush head seat is detachably connected to the brush handle via the elastic member; and the elastic member can buffer the shaking of the brush head seat relative to the brush handle. When replacing the brush head, a user can remove the brush head separately from the mounting slot, and the brush handle does not need to be replaced, such that the disassembly of a connection structure of the brush handle and a driving device can be avoided, reducing the damage caused thereto, and reducing the replacement and waste of the brush handle, wherein same is more environmentally friendly and energy saving. Moreover, after the brush head is replaced, a brush head can still be firmly connected to the brush handle via the elastic member, and the elastic member can buffer the shaking of the brush head seat relative to the brush handle, so that the electric toothbrush does not easily generate noise when working.
