Document Type and Number:
WIPO Patent Application WO/2023/087855
Kind Code:
A1
Abstract:
The present invention relates to a rotary electric toothbrush, comprising a handle body and a toothbrush head assembly. The toothbrush head assembly comprises a base, an outer ring bristle mounting seat, and an inner ring bristle mounting seat. The base is mounted on the handle body, and both the outer ring bristle mounting seat and the inner ring bristle mounting seat are rotatably disposed on the base, the outer ring bristle mounting seat being located at an outer side of the inner ring bristle mounting seat, and the toothbrush head assembly further comprises a drive assembly simultaneously driving the outer ring bristle mounting seat and the inner ring bristle mounting seat to rotate in a reciprocating manner. The drive assembly comprises a motor apparatus and a transmission rod, the motor apparatus being fixedly disposed in the handle body, and the transmission rod being rotatably disposed on the base along a length direction of the handle body. An output shaft of the motor apparatus can drive the transmission rod to rotate, so that the transmission rod simultaneously drives the outer ring bristle mounting seat and the inner ring bristle mounting seat to rotate in a reciprocating manner by means of an eccentric structure. Using the described solution, the outer ring bristle mounting seat and the inner ring bristle mounting seat simultaneously rotate in a reciprocating manner, the structure is simple, and tooth cleaning effects are improved.
