Description

Toothbrush handle and toothbrush

Technical field

The invention relates to a toothbrush handle and a toothbrush.

Background technique

Brushing is an important health care method for people to remove plaque, soft dirt and food residues in their lives and maintain oral hygiene. Among them, the Pap smear method, also known as the gingival sulcus cleaning method or the horizontal tremor method, is a method recommended by the American Dental Association to effectively remove the plaque near the gingival margin and the gingival sulcus. The main method of brushing is to brush the toothbrush with the tooth. The long axis points at a 45° angle to the direction of the apex of the tooth (the upper jaw is upward and the lower jaw is downward), so that part of the bristles enters the gingival sulcus to clean the plaque in the gingival sulcus. The shape of the handle portion of the existing toothbrush is not favorable for the user to control or sense the position and angle of the bristle portion in the gingival sulcus, which is not conducive to cleaning the plaque in the gingival sulcus, which brings inconvenience to the user's use and experience.
