Toothbrush head and use principle thereof

Abstract

The invention relates to a toothbrush head and a use principle thereof. The toothbrush head comprises a body and a brush part arranged at the end of the body, the brush part comprises a plurality of first bristle clusters and a plurality of second bristle clusters, the first bristle clusters are arranged in a U shape to form a U-shaped bristle cluster group, and the plurality of second bristle clusters are arranged in the U-shaped bristle cluster group and are arranged along the direction of a brush handle to form a linear bristle cluster group; the height of the first bristle clusters is greater than that of the second bristle clusters; the upper side of the U-shaped bristle cluster group and the linear bristle cluster group achieve the positioning and supporting of the brush part respectively, so that the moving direction of the brush part is effectively limited, the brush part cannot move longitudinally during transverse tooth brushing, and the brush part is perfectly matched with key essentials required in the Babbitt's tooth brushing method. Therefore, the use of the toothbrush head is convenient and labor-saving, the cleaning effect on the surface of the whole dental crown and the whole slit between teeth is greatly improved, the cleaning range is expanded, and meanwhile, gingival sulcus and gingival margin can be effectively and accurately cleaned.

Description

technical field [0001] The invention relates to a toothbrush head and its usage principle. Background technique [0002] Along with the continuous progress of society, people's oral problems are becoming more and more serious, the main reason is that the diversification of diet and the untimely cleaning of oral cavity, and toothbrush is a kind of common oral cavity cleaning articles for use. [0003] At present, brushing teeth with Pasteur brushing method is a widely recognized way of brushing teeth. Pasteur brushing method is also called gingival sulcus cleaning method or horizontal vibration method. The method of bacterial plaque in the ditch; when using, point the toothbrush and the long axis of the tooth at a 45° angle to the root tip (the toothbrush is upward when brushing the upper teeth, and the toothbrush is downward when brushing the mandibular teeth), tilting towards the gum and dental junction, so that One part of the bristles enters the gingival sulcus, the othe...

AI Technical Summary

Problems solved by technology

[0004] Although the Pasteur brushing method is an effective way of brushing teeth, the brush heads on the existing common toothbrushes and electric toothbrushes on the market cannot match the key essentials required in the Pasteur toothbrushing method, because the brush heads on the existing toothbrush The height of each group of tufts is the same. When the tufts located in the middle of the brush head lean against the surface of the tooth enamel, some of the tufts located on the upper and lower sides of the brush head are not even attached to the crown or gums. Therefore, only some hair tufts located in the middle of the brush head actually play a cleaning role, and the cleaning range is small, and the brush head will move frequently between the teeth and the gums due to the lack of positioning support when the brush head moves, which cannot always be correct. The gap between the teeth is effectively cleaned, so the cleaning effect is poor; if you insist on sticking the bristle tufts in the middle of the brush head to the surface of the enamel, you need to continuously press the toothbrush with a large force, which is extremely inconvenient to use, and The tufts on the underside of the brush head will cause damage to the gums due to excessive pressing on the gums, which needs further improvement
