Abstract

The utility model is a toothbrush, including a brush head, brushes and a handle. The toothbrush is characterized in that the cross section of the brushes is compressed shape, such as elliptic, fillet rectangle and diamond shapes. The brushes are equipped with a relative low hardness in a minor axis direction of the cross sections and a relative high hardness in a long axis direction. When a short axis of the cross section of the brushes is parallel to a long axis of the brushes, the brushes are equipped with the relative high hardness along the brush head transverse (short) direction and the relative low harness along the brush head vertical (long) direction. The cleaning function during the vertical tooth-brushing is strengthened when the toothbrush is used and stimulations and damages on gingival are reduced during the transverse tooth-brushing. And the toothbrush is hard when in vertical use and soft when in transverse use.

Description

The flat bristle toothbrush

The utility model relates to a kind of toothbrush, belongs to daily living article.

People use toothbrush to wish when reaching cleaning teeth, oral cavity effect, the few stimulation and the damage gum.For reaching the effect of cleaning, bristle harder for well; Be to reduce stimulation and damage to gum, bristle is softer for well.At present, the brushed toothbrush of employing, soft bristle tooth brush, frizzle toothbrush etc., the cross section of its bristle are circular, all have same hardness (bending resistance curvature) on all directions of transverse cross-section parallel.

The purpose of this utility model is that a kind of improved toothbrush will be provided, the bristle of toothbrush with the different directions of the transverse cross-section parallel of bristle on have different hardness (bending resistance curvature).It has hard in one direction in use, and on perpendicular direction soft effect, give tooth, different cleaning action and the stimulation degree in oral cavity.

The purpose of this utility model is achieved in that adopting cross section on the brush of toothbrush is the bristle of flat, as: the analogous shape of ellipse, fillet rectangle, fillet rhombus or some variation.The cross section of such bristle has minor axis and major axis, has its relative soft (low relatively bending resistance curvature, soft) on short-axis direction, and is flexible; On the major and minor axis direction, have its relative high rigidity (the high bending degree is hard relatively), not flexible.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cross sectional representation of bristle of the present utility model;

Fig. 3 is the front elevational schematic of brush of the present utility model from the bristle one side.

Among Fig. 1, bristle (2) is fixed on the brush (1) with tuftlet, and brush (1) links to each other with lever (3).Among Fig. 2, the cross section of bristle (2) is ellipse (4) or fillet rectangle (5) or fillet rhombus (6), its minor axis of each tool (a) and major axis (b).Among Fig. 3, brush tool minor axis (x) and major axis (y) are with direction.

In one embodiment, bristle (2) parallels with the major axis (y) of brush (1) with the minor axis (a) of its cross section; Major axis (b) parallels with the minor axis (x) of brush (1).Bristle (2) is a relative high rigidity, not flexible on (x) of brush direction of principal axis; On (y) of brush (1) direction of principal axis is relative soft, flexible.In use when the toothbrush vertical motion, promptly when the direction of growth of tooth moved around, bristle (2) was on relative high rigidity, the unbending direction, the cleaning action that plays; When the toothbrush transverse movement, promptly when the vertical direction of the direction of growth of tooth moved around, bristle (2) was on relative soft, the flexible direction, has reduced stimulation and damage to gum.Briefly, be exactly that perpendicular brush is hard, horizontal brush is soft.

In another embodiment, bristle (2) is with the arbitrarily configuration of major axis (y) of minor axis (a) with the brush (1) of its cross section.The bristle that relative high rigidity and relative soft then, are all arranged on all directions to (y) direction of principal axis on (x) of brush direction of principal axis.

In the utility model, brush (1) can use cross section to be the bristle of flat and the cross section bristle as circle simultaneously.

Claims

1. a toothbrush comprises brush (1), bristle (2) and lever (3), it is characterized in that: bristle (2) is that cross section is the bristle of flat.

2. toothbrush according to claim 1 is characterized in that: the cross section of bristle (2) is the analogous shape of ellipse (4) or fillet rectangle (5) or fillet rhombus (6) or some variation, and cross section major axis (b) and minor axis (a) are arranged.

3. toothbrush according to claim 1 is characterized in that: brush (1) part is used the bristle of cross section as flat, and part is used the bristle of cross section as circle.
