Accompanying drawing explanation
Fig. 1 is the cross-sectional view that the present invention is perpendicular to the long limit of head toothbrushes substrate.
Fig. 2 is the detail view of hard fine, soft fur and soft fine, soft fur in the present invention.
Referring to Fig. 1-2,1 is middle bristle, and 2 is fur, and 3 is head toothbrushes substrate, 1.1 be in hard fine, soft fur, 1.2 is soft fine, soft fur.
Detailed description of the invention
Referring to Fig. 1-2, the present invention is the toothbrush of a kind of abrasion that can effectively reduce dental surface, including middle bristle 1, fur 2, head toothbrushes substrate 3, in hard fine, soft fur (1.1), soft fine, soft fur 1.2.
Referring to Fig. 1, including middle bristle 1, fur 2, head toothbrushes substrate 3；Described middle bristle 1 is parallel to the long limit of described head toothbrushes substrate 3, and the outside being positioned at the both sides of described head toothbrushes substrate 3 arranges, and described fur 2 is parallel to the long limit of described head toothbrushes substrate (3), and is positioned at the intermediate arrangement of described head toothbrushes substrate 3.
The middle bristle 1 of outside arrangement is used to reject the food debris in teeth space, and the fur 2 of intermediate arrangement is used to the dirt of teeth surfaces.Owing to middle bristle 1 hardness is relatively high, so being easier to reject the food debris in teeth space, and fur 2 is relatively soft, so can reduce the abrasion to tooth itself while teeth surfaces dirt.
Correct teeth brushing way is to brush along the direction of dental growth, and namely tooth above is brushed downwards, and tooth below is upwards brushed.This teeth brushing way determines the bristle in outside and contacts the food debris in teeth space at first.Therefore middle bristle 1 is arranged on the outside on the both sides of head toothbrushes substrate 3.
The angle of the root of described middle bristle 1 and the upper surface of head toothbrushes substrate 3 is α, α is 75 °；Middle this angle of inclination of bristle 1, when using same dynamics, the probability rejected by the food debris deeply ensconcing teeth crevice is bigger.
The tippy tea of described middle bristle 1 is at same horizontal plane, and the angle of the plane that this horizontal plane is formed and described fur 2 is β, β is 45 °--and 60 °.So the effect of design is that the tippy tea of middle bristle 1 is at same horizontal plane, the angle of inclination of the plane that this horizontal plane is formed forms a wedge shape, those skilled in the art should know, when brushing teeth, the tippy tea of the middle bristle 1 of wedge shape is at same horizontal plane, the plane that this horizontal plane is formed is than the tippy tea of horizontal plane at same horizontal plane, and the plane that this horizontal plane is formed is easier to insert in teeth space.So design another effect and be just so that toothbrush is when the dirt of teeth surfaces, the tippy tea of middle bristle 1 is at same horizontal plane, the plane that this horizontal plane is formed is owing to being wedge shape, the area of contact dental surface only limits the tip with wedge shape, the bristle 1 abrasion to dental surface in so can reducing.Proving through test of many times, when β is too small, middle bristle (1) tip is meticulous, causes that middle bristle 1 integral hardness is inadequate, it is impossible to effectively reject out from teeth space by food debris；When β is excessive, middle bristle 1 tip is excessively blunt, it is impossible to effectively insert in teeth space.
Through test of many times, show that the quantity of described fur 2 and described middle bristle 1 is than for 4:1, show that this ratio is fur 2 and the best proportion of middle bristle 1 through test of many times, can reach to reject the effect of food debris in teeth space, again can teeth surfaces effectively, and reduce the abrasion of dental surface.
One end of described middle bristle 1 arrange described in hard fine, soft fur 1.1, the top of the lateral surface of described fur 2 arranges soft fine, soft fur 1.2.So the effect of design is owing to middle bristle 1 is rejected in the process of the food debris in teeth crevice, and these food debriss are the tippy tea dropping on described middle bristle 1 re-entrant angle at same horizontal plane, the plane that this horizontal plane is formed and described fur 2 mostly.This is because the tippy tea of middle bristle 1 is at same horizontal plane, the plane that this horizontal plane is formed is a slope, and food debris can slip in re-entrant angle along slope.Hard fine, soft fur 1.1 and the interlaced formation net plane of soft fine, soft fur 1.2 in making, so can effectively stop food debris in teeth space to fall into re-entrant angle and drop to bristle root therewith.And the residue dropped between hard fine, soft fur 1.1 and soft fine, soft fur 1.2 is due to the upper strata at bristle, so being easily washable clean.So design alsos for reducing production cost, it is known that, one end of described middle bristle 1 arrange described in hard fine, soft fur 1.1 than one end of described middle bristle 1, described soft fine, soft fur 1.2 or other bristle are set for simply too much production technology, therefore becoming to produce cost also can be much lower.
Apart from one another by for 0.7mm between hard fine, soft fur 1.1 in described.Lateral surface on described fur 2 top arranges a described soft fine, soft fur 1.2 every the distance of 1.5mm.In hard fine, soft fur 1.1 interval more than 0.7mm, soft fine, soft fur 1.2 interval is more than 1.5mm, it is impossible to stop food debris to drop to bristle root.Adding up according to scientific experimentation, the diameter of the food debris in teeth crevice about 80% is within the scope of 0.73mm 1.35mm.And the food debris that length is in the teeth crevice of 1.5mm 3.5mm accounts for 80%.Owing to hard fine, soft fur 1.1 and soft fine, soft fur 1.2 are that interlaced arrangement can stop that most food debris falls into the root of bristle.
The tippy tea of described middle bristle is at same horizontal plane, and the tippy tea of described soft fine, soft fur is at same horizontal plane, and the plane that the tippy tea of soft fine, soft fur described in the plan range that the tippy tea of middle bristle is formed is formed is 0.7mm.In described hard fine, soft fur at same horizontal plane, the distance 0.5mm--0.7mm of the side of fur described in the plan range that this horizontal plane is formed.Owing to the diameter of the food debris in teeth crevice about 80% is within the scope of 0.73mm 1.35mm.And the food debris that length is in the teeth crevice of 1.5mm 3.5mm accounts for 80%.So most food debris so can be made to be unlikely to fall into the root of bristle.And so can reduce in the process of brushing teeth, in hard fine, soft fur 1.1 and described fur 2, and the friction between soft fine, soft fur 1.2 and middle bristle 1, so can extend the service life of toothbrush.
In the process brushed teeth, fur 2 is perpendicular to dental surface, and described soft fine, soft fur 1.2 is vertical with described fur 2.So soft fine, soft fur 1.2 is parallel to dental surface, is similar to the effect of grid, thus can play the food debris stopped in teeth crevice to greatest extent and drop in the effect of bristle root.
In hard fine, soft fur 1.1 1 aspect act the food debris stopped in teeth crevice and drop in the effect of bristle root.On the other hand, it is also possible in auxiliary, bristle 1 rejects the food debris in teeth crevice.Because in hard fine, soft fur 1.1 than in bristle 1 more tiny, and higher than the hardness of soft fine, soft fur 1.2, it is possible to go deep into teeth crevice is rejected more tiny food debris.In described, hard fine, soft fur 1.1 is vertical with described middle bristle 1, is the formation of similar " √ ", it is easier to by food debris, from teeth space, hook is out.
In order to the angle of the upper surface of the root Yu head toothbrushes substrate 3 of determining middle bristle 1 is α, the tippy tea of described middle bristle 1 is at same horizontal plane, the angle of the plane that this horizontal plane is formed and described fur 2 is β, when taking any value, that brushes teeth is most effective, namely toothbrush can be more rapid, it is easier to is rejected from teeth space by food debris.Carry out following test.
