Abstract

An efficient toothbrush is characterized in that the height of bristles mounted on a brush head increases from center outward, wherein, the center bristles are lower than the peripheral ones and the bristles are arranged in a stepped manner; the cleaning surface is scoop-shaped concave structure. The tufts of bristles at both sides are allowed to be pushed to the center; a concave cleaning surface is preferred in a longitudinal direction in order to suit teeth profile. The utility model has advantages that flexible, rigid, short and long bristles are all available for different cleaning applications, in which, the center bristles are short and rigid and being contrived for cleaning tooth chinks; the side bristles are long and flexible and being developed to expand cleaning area and clean tooth cervixes, thereby, the toothbrush can not only clean the lower portions such as tooth chinks and tooth cavities but also clean the tooth cervixes, which can avoid possible damages of gums at the same time.

Description

The toothbrush that a kind of cleaning effect is good

Technical field

The utility model relates to toothbrush, particularly a kind of toothbrush that increases cleaning effect.

Background technology

Though the toothbrush kind is more at present, the bristle end face mostly is planar shaped or whole concave shape.Bristle is stressed comparatively average when brushing teeth, and bristle is difficult to distortion, and the rigidity that seems is bigger, is difficult to clean the recess of tooth, as positions such as teeth space, tooth nest and necks.The toothbrush of this class shape, on the one hand bristle can't be deep between the backlash, on the other hand since bristle fall short of, during pressurized distortion little, the cleaning area is restricted.Use existing toothbrush, be subjected to the strongest several teeth of toothbrush active force damage also very easily to occur.Because neck portion is the intersection of corona and root of the tooth, the thing residue of easily suffering from indigestion.The influence of the posture of being brushed teeth, people brush teeth and seldom brush neck portion in the process, ignore the cleaning to this part easily, easily form tartar in the course of time.After the bristle of existing toothbrush uses a period of time, all can outward-dipping or outside turnup, cause result of use and life-span to descend.

Summary of the invention

The purpose of this utility model is the above-mentioned shortcoming that will overcome existing toothbrush, provides a kind of cleaning effect better toothbrush, not only can brush flank of tooth recess, and can be able to increase the cleaning area of bristle, is suitable for cleaning neck portion.

Solution of the present utility model comprises brush holder and bristle tuft, it is characterized in that: the height of bristle tuft increases from center to periphery gradually, and the bristle tuft in centre is lower, and peripheral bristle tuft is higher, is step-like, and whole brush finish is a spoon shape concave surface.

The bristle tuft of above-mentioned toothbrush both sides can be beneficial to increase cleaning effect to centroclinal.

The bristle tuft of above-mentioned toothbrush preferably longitudinally is the concave panel that adapts with tooth.

The utility model is compared with existing toothbrush, has following advantage:

1. the bristle on toothbrush has and long weak point is arranged, and having gentlely has just, can bring into play advantage separately.The short hard bristle in center, more strong, be suitable for cleaning the tooth crack.Outside bristle is grown softer and is sloped inwardly, and expands outwardly during pressurized, can increase the cleaning area, is suitable for cleaning neck portion.Bristle becomes by sloping inwardly when outward-dipping, and deflection is bigger, and elasticity is bigger, and cleaning effect is also better.

2. can clean down flank of tooth lower position such as teeth space, tooth nest, also can clean down neck portion, simultaneously the Anti-dental injury gum.

3. toothbrush both sides bristle tuft slopes inwardly in advance, helps preventing that bristle from turning up, and prolongs toothbrush service life.

4. long outside bristle can play the effect of massage gum, can promote the gum blood circulation, promotes the health of tooth, periodontium.

Description of drawings

Fig. 1 is the transverse views of the utility model toothbrush head.

Fig. 2 is vertical view of Fig. 1 toothbrush.

The specific embodiment

Referring to accompanying drawing, the improvements of this toothbrush are only at head toothbrushes, so brush holder part 1 is not drawn entirely.With the vertical view of Fig. 2 is example, and some bristle tuft 3 in centre are minimum, and the 3-5 bundle is arranged usually.Inferior outer 4 is higher, and outermost layer 5 is the highest, is three grades of stairsteppings.Equally, from Fig. 1 laterally, the ectonexine bristle also is three grades of stairsteppings.The height that is bristle increases from center to periphery gradually.Whole bristle end face forms one spoonful of shape concave surface.Certainly, the ectonexine bristle also can be not limited to stairstepping, but continuous transition.The comparable ordinary toothbrush of this toothbrush is wide slightly.The bristle that makes long fur and lack can better be brought into play advantage separately.Becoming mildewed of the outside, since soft easily deformable, can brush tooth neck position, increased cleaning area and cleaning effect.The undercoat good rigidly in centre is easy to keep vertical shape, is fit to very much cleaning tooth crack.

Referring to Fig. 2, the

bristle tuft

4,5 of head toothbrushes both sides promptly slopes inwardly preferably to centroclinal.When expanding outwardly when being under pressure like this, can produce bigger distortional stress, can restore to the original state when running into the tooth crack, the better effects if in cleaning tooth crack, the area of cleaning is also bigger.Toothbrush both

sides bristle tuft

4,5 slopes inwardly in advance, helps preventing that bristle from turning up, thereby prolongs the service life of toothbrush.

Among Fig. 1 outermost layer bristle tuft 5 can take arc or with the shape that teeth arrangement adapts, the part bristle is shortened, to improve rigidity.But also unsuitable too short, otherwise cause the cleaning area to descend.Inferior outer bristle tuft 4 is taked arc equally, keeps less difference in height with outermost layer, improves bristle rigidity with appropriateness.Simultaneously, make the bristle on the toothbrush have various flexibility, thereby the different separately effect of performance can enlarge the cleaning area, can strengthen cleaning effect again again than the short bristles softness in centre.

Claims

1, the good toothbrush of a kind of cleaning effect comprises brush holder (1) and bristle tuft (2), it is characterized in that: the height of bristle tuft (2) increases from center to periphery gradually, the bristle tuft in centre (3) is lower, peripheral bristle tuft (5) is higher, is step-like, and whole brush finish is a spoon shape concave surface.

2, toothbrush as claimed in claim 1, the bristle tuft (4,5) that it is characterized in that both sides is to centroclinal.

3, toothbrush as claimed in claim 1 is characterized in that said bristle tuft (2) longitudinally is the concave panel that adapts with tooth.
