Description

The electric toothbrush of positive and negative rotation

This utility model relates to a kind of electric toothbrush device of the positive and negative rotation of cleaning and taking care of one's teeth.

CN87213981U discloses a kind of electric toothbrush, and its weak point is the bristle position with the convex surface design, and it is to brush labial teeth position, but internally tooth brush in harmony in the exterior both sides is unclean, does not all establish display lamp, brush lid, so bad make and easily by germ contamination.
