Title:
TOOTHBRUSH HAVING IMPROVED GRIP HANDLE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/012072
Kind Code:
A1
Abstract:
A toothbrush provided by the present invention comprises a grip handle and a toothbrush head. The grip handle and the toothbrush head are connected by means of a twistable portion; the twistable portion is provided with at least one connection piece; the connection piece has a thickness smaller than that of the grip handle; the angle of the toothbrush head can be changed along with the pressure applied by a user; when the brushing force exceeds a preset force value, the twistable portion is elastically deformed to bend or turn the toothbrush head; when force exceeding a default value is removed, the twistable portion can restore its original state by means of its own elastic force and return the toothbrush head to its original position. Therefore, the use of the twistable portion can absorb some of the brushing force, thereby reducing the brushing force applied on the tooth surfaces and gums, and reducing the damage to the teeth and gums.
