Title:
TOOTHBRUSH HAVING IMPROVED GRIP HANDLE
Document Type and Number:
WIPO Patent Application WO/2021/012070
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 twist piece; the twist piece forms at least one twist by using the center thereof in the length direction as a twist axis to form a helical toothbrush neck, so that the entire toothbrush head has elastic deformation with respect to 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 twist piece is elastically deformed to bend or turn the toothbrush head; when force exceeding a default value is removed, the twist piece 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 twist piece 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.
