Three-brush combined rotating type toothbrush head

Abstract

The invention relates to the technical field of oral health and sanitation, and discloses a three-brush combined rotating type toothbrush head, which comprises brush heads, a protective cover and a transmission device. The brush head is cylindrical, bristles are arranged on the cylindrical surface of the brush head, and rotating shafts are arranged at the two ends of the brush head. Wherein the three brush heads are respectively a top brush, a left side brush and a right side brush, the axes of the brush heads are parallel to one another, and the three brush heads are arranged in a delta shape; the protective cover is a U-shaped curved surface; three pairs of shaft sleeves are arranged at two ends of the protective cover and correspond to the rotating shafts of the three brush heads respectively; a left brush and a right brush are arranged at the opening of the protective cover; a top brush is arranged at the bottom of the protective cover; a connector is arranged at the end of the rotating shaft at the bottom of the top brush, and a transmission device is arranged among the three brush heads. The toothbrush head has the advantages that the arrangement mode of the bristles meets the ergonomic requirements of the teeth, the gingiva is not damaged, the joint part of the gingiva and the teeth is uniformly stressed, bruising grooves are not formed, three surfaces of the teeth are simultaneously cleaned, the force of each bristle contacting the teeth is stable, the contact is comfortable, and the cleaning efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of oral health and hygiene, and particularly relates to a three-brush interlocking toothbrush head. Background technique [0002] Most of the existing brush heads are of the flat brush type. Whether it is a manual or electric rotating toothbrush, the tops of the bristles do a back-and-forth reciprocating motion or a circular motion on the tooth surface. The problem with this is that it is easy to damage the gums and enter the gum coverage area to cause gum damage and recession. Brushing with a reentry motion for a long time results in damage to the junction of the gums and the teeth, and a brushing groove is formed in the junction. Moreover, when brushing teeth, the flat-brush type toothbrush head is not easy to protrude into the concave surface between adjacent teeth, resulting in unclean brushing, and the long-term accumulation of residues forms calculus, causing bad breath and periodontal disease.

AI Technical Summary

Problems solved by technology

Moreover, when brushing teeth, the flat brush type toothbrush head is not easy to penetrate into the concave surface between adjacent teeth, resulting in unclean brushing, long-term accumulation of residues and formation of stones, resulting in bad breath and periodontal disease

Moreover, most people use a lot of force in the process of brushing their teeth, which causes the bristles to fall over in a short period of time. After the bristles fall, the brush head will cause more serious damage to the gingival junction, and the cleaning function of the teeth will also decline accordingly, so it has to be replaced in advance.

People can't control the strength well during the brushing process, resulting in unstable pressure and direction of the bristles on the gums and teeth, and frequent scratches on the gums and the inner wall of the cavity, especially children who have not mastered the correct brushing method. Cause damage and resist brushing

Moreover, the existing toothbrush has only one brush head, which can only brush one side of the teeth in one contact. It is necessary to adjust the direction of the brush head to complete the cleaning of the inner and outer sides of the teeth and the crown, which makes the brushing time long and cannot meet people's increasingly accelerated pace of life.
