Abstract

The utility model discloses a curved surface toothbrush, which comprises a brush body (1) and bush hair (2). The brush body (1) comprises a brush handle (11) for a hand to hold and a brush head (12), wherein the bush handle (11) and the bush head (12) are connected into a whole body. The bush hair (2) consists of a plurality of bundles of bush hair. One end of each bundle of bush hair is fixed on the brush head (12). A brushing surface (21) is formed by the other ends of a plurality of bundles of bush hair. The brushing surface (21) is an upwards convex spherical one. Both upper and lower surfaces (121, 122) of the brush head (12) are curved ones parallel to the brushing surface (21). The direction of each bundle of bush hair is the same with that of a normal line of the brushing surface (21) at the corresponding position of the brushing surface (21) on which the bundle of bush hair is positioned. By the curved surface toothbrush, residue dirt in slit among teeth, at front surfaces of the teeth, at back surfaces of the teeth and upper and lower meshing surfaces of the teeth can be effectively cleared; the bush hair has good insertion force for holes of the teeth and the slits among the teeth; and the bush hair are difficult to fall over and are durable.

Description

The curved surface toothbrush

Technical field

The utility model relates to a kind of toothbrush, particularly a kind of curved surface toothbrush.

Background technology

The toothbrush of people's use at present, it comprises brush body and bristle, and brush body comprises brush holder that is used to shake hands and the brush that is connected in one, and bristle is made up of multi beam, and an end of every bundle bristle is fixed on the brush, and its other end forms brush finish, and brush finish is a planar structure; The brush finish of this toothbrush and people's oral cavity structure are misfitted, and people's bristle in use tend to existing damage gum, cause the uncomfortable even bleeding gums of people, and this toothbrush can not be cleared up the food residual on tooth and the gum well.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of curved surface toothbrush is provided, it can be cleared up tooth break joint, leading flank, the tooth back side, the last lower teeth field of conjugate action effectively, go up the residue dirt of lower teeth end of engagement front and back corner, can not damage gum yet, and durable in use.

The technical solution of the utility model is: a kind of curved surface toothbrush, it comprises brush body and bristle, brush body comprises brush holder that is used to shake hands and the brush that is connected in one, bristle is made up of multi beam, one end of every bundle bristle is fixed on the brush, the other end of plurality of bristles forms brush finish, and brush finish is the curved surface that raises up.

The further technical scheme of the utility model is: described brush finish vertically is the circular arc that raises up along brush body.

The utility model further technical scheme is: described brush finish is 20 to 100 millimeters along the arc radius that vertically is the circular arc that raises up of brush body, and is higher one to three millimeter than two ends in the middle of the brush finish.

The utility model more further technical scheme be: described brush finish laterally is circular arc along brush body, i.e. the cross-sectional line of brush finish is a circular arc line.

The also further technical scheme of the utility model is: the upper and lower surface of described brush is the curved surface parallel with brush finish.

The further technical scheme of the utility model is: the direction of described every bundle bristle is identical with the brush finish normal direction of the relevant position of its brush finish of living in.

The utility model compared with prior art has following characteristics:

1, the circular arc brush finish can be cleared up the residue dirt of tooth break joint, leading flank, the tooth back side, the last lower teeth field of conjugate action, last lower teeth end of engagement front and back corner effectively, also can not damage gum;

2, bristle becomes the fan type to launch, and hair side increases, and bristle has interspersed preferably power to hole, hole, the slit of tooth; Cleaning to toothbrush is more convenient, and is cleaner;

3, the circular arc brush finish becomes the fan type to launch to make bristle to be difficult for lodging with bristle, and is durable in use.

Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.

The specific embodiment

Embodiment 1

Shown in Fig. 1-2: a kind of curved surface toothbrush, it comprises brush body 1 and bristle 2, brush body 1 comprises brush holder that is used to shake hands 11 and the brush 12 that is connected in one, bristle 2 is made up of multi beam, one end of every bundle bristle is fixed on the brush 12, the other end of plurality of bristles forms brush finish 21, the circular arc (as shown in Figure 1) that brush finish 21 raised up along vertically being of brush body 1, the intersection that is brush finish 21 and vertical section is a circular arc line, the radius of this circular arc is 20 to 100 millimeters, be R=20～100mm, higher one to three millimeter in the middle of the brush finish 21 than two ends, be H=1～3mm, brush finish 21 vertically also can be the convex arc of other pattern (elliptic arc for example along brush body 1, conic section, cubic curve etc.); Brush finish 21 is along laterally linearly (as shown in Figure 2) of brush body 1, i.e. brush finish 21 is a straight line with the intersection in cross section; The upper and lower surface of brush 12 (121,122) is the curved surface parallel with brush finish 21; The direction of every bundle bristle is identical with brush finish 21 normal directions of the relevant position of its brush finish 21 of living in, and promptly bristle becomes the fan type to launch.

Embodiment 2

As shown in Figure 3: a kind of curved surface toothbrush, the main distinction of itself and embodiment 1 be brush finish 21 along brush body 1 laterally be circular arc (as shown in Figure 4), i.e. brush finish 21 is a circular arc line with the intersection in cross section; When vertical circular arc of brush finish 21 when laterally arc radius is identical, brush finish 21 is spherical shape (spherical calotte) just; Other structure technology feature is with embodiment 1.

Embodiment 3

As shown in Figure 5: a kind of curved surface toothbrush, its main distinction with embodiment 1 are that the upper and lower surface (121,122) of brush 12 is all not parallel with brush finish 21; Other structure technology feature is with embodiment 1.

The utility model is not limited to above-mentioned concrete structure, just drops within the protection domain of the present utility model so long as brush finish 21 is the curved surface that raises up.
