Abstract

The utility model relates to a tooth brushing device with three-brush, which is composed of three improved toothbrushes (one bottom brush and two side brushes) connected by a resilient means, wherein brush bristles of three sides of the three toothbrushes form a shape surrounding cheek tooth crowns. When a person brushes teeth, the distance among brush bristles of the three toothbrushes is adjustable under the action of the resilient device, which can ensure that the tips of the brush bristles contact the surfaces of the tooth crowns thoroughly. The utility model can realize that teeth are cleaned quickly.

Description

Three brush tooth brushing devices

The utility model relates to human teeth protection, particularly relates to the tooth brushing device after a kind of the improvement.

The toothbrush that present people generally use all is to be made of a bristle, and this toothbrush brush speed is slow, and the used time is long, inefficiency.And the medial surface of the very difficult outwash tooth of existing toothbrush (near the corona side of inside, oral cavity), be unfavorable for the protection of tooth.

The purpose of this utility model provides the tooth brushing device after a kind of the improvement, and it is each position of outwash tooth rapidly.

People's tooth is divided into front tooth (4 pairs), canine tooth (2 pairs), premolar teeth (4 pairs) and molar (6 pairs), and the shape of these teeth has many similarities, arranges very regular between tooth.According to these characteristics, the utility model adopts end brush, side brush (A) and side brush (B) three handle toothbrushes in conjunction with formation.Wherein side brush (A) and side are brushed the complete radial symmetric of (B) shape, and they lean against brush both sides, the end, and three handle toothbrush bristles are adjacent to each other, form the shape of surrounding the molar crown.Brushes brush holder in both sides is near end brush brush holder, and three brush holders and are connected to each other with elastic device in the same way endways, and this elastic device can make not only that distance can change between two sides brushes, and can make that distance can change between end brush and the side brush.When brushing teeth, can use two side brushes or three toothbrushes simultaneously.Thereby guaranteed each position of outwash tooth rapidly.

The utility model is because the toothbrush after only need improving three handles with elastic device couples together, so relatively simple for structure; And, can scrub the surface, a few place of tooth simultaneously, so can brush teeth fast because of the bristle arrangements and the teeth patterning of this device coincide; Scrub the tooth medial surface and become easily because of the existence that side brush is arranged makes in addition, help the outwash tooth.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a concrete installation drawing of the present utility model, wherein, Fig. 1-the 1st, front view, Fig. 1-2 are vertical views, Fig. 1-the 3rd, front view C-C is to cutaway view.

Fig. 2 and Fig. 3 are two kinds of concrete brush holder syndetons in the device shown in Figure 1, and wherein, Fig. 2-1 and Fig. 3 the-the 1st, front view, and Fig. 2-2 and Fig. 3 the-the 2nd, vertical view, Fig. 2-3 and Fig. 3 the-the 3rd, and front view A-A is to cutaway view.

Device shown in Figure 1 comprises side brush (A) [1], end brush [2] and side brush (B) [3], and they link together with bolt [6] by flexure strip [4] and [5].

Side brush brush holder leans on into end brush brush holder among Fig. 1, can make when scrubbing the tooth medial surface, and tooth does not hinder the motion of the utility model device.

A is the angle excursion of side brush among Fig. 1, and its value is preferably between 5 °～15 °, and this helps side brush bristle tips and the tooth crown coincide.H brushes the bristle tips difference in height in the end, and its value is preferably between 0～2mm, and this helps the channel form structure at outwash molar and premolar teeth crown tip.X is two side brush bristle tips distances, be preferably in about 10mm apart from x, under the effect of flexure strip [4], x preferably can regulate in 0～20mm scope, y is end brush bristle tips and side brush bristle tips distance, and distance y is preferably in about 2mm, under the effect of flexure strip [5], y preferably can regulate in 0～5mm scope, and this helps use of the present utility model.

Before brushing teeth, toothpaste is coated in the end brushes, the brush of pinching side then (A) [1], end brush [2] and side are brushed (B) [3], make its bristle adjacent to each other, promptly are in minimum of a value apart from x and y, and toothpaste just is evenly coated in and respectively brushes bristle tips.When scrubbing molar and premolar teeth, use simultaneously side brush (A) [1], end brush [2] and side brush (B) [3], and distance X and Y are transferred to fit value, this device of horizontal movement.When scrubbing front tooth and canine tooth, use simultaneously side brush (A) [1] and side brush (B) [3], and distance X and Y are transferred to fit value, this device of horizontal movement.

Elastic device uses sheet metal to constitute among Fig. 1.

Elastic device is that all-plastic (rubber) constitutes among Fig. 2, meets instructions for use of the present utility model, can reduce production costs again.

Elastic device is above both combination among Fig. 3, meets instructions for use of the present utility model equally.
