See 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
See Fig. 1-2, the present invention is a kind of toothbrush efficiently, comprises middle bristle 1, fur 2, head toothbrushes substrate 3, in hard fine, soft fur (1.1), soft fine, soft fur 1.2.
See Fig. 1, comprise 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 is positioned at the outside arrangement on the both sides of described head toothbrushes substrate 3, 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 swill in teeth space, and the fur 2 of intermediate arrangement is used to the dirt of teeth surfaces.Because middle bristle 1 hardness is relatively high, so than the swill be easier in ones teeth seam, and fur 2 is relatively soft, so can reduce the wearing and tearing to tooth itself while teeth surfaces dirt.
Correct teeth brushing way brushes along the direction of dental growth, and the tooth is namely brushed downwards, and tooth below is upwards brushed.Bristle outside this teeth brushing way determines contacts the swill 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 of being rejected by the swill of deeply ensconcing teeth crevice is larger.
The high-quality green 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 °.The effect of such design is that the high-quality green 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 high-quality green 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 high-quality green tea of horizontal plane at same horizontal plane, and the plane that this horizontal plane is formed more easily is inserted in teeth space.Another effect of such design is exactly make toothbrush when the dirt of teeth surfaces, the high-quality green tea of middle bristle 1 is at same horizontal plane, the plane that this horizontal plane is formed is owing to being wedge shape, contact the area of dental surface only for the tip with wedge shape, the wearing and tearing of bristle 1 pair of dental surface in can reducing like this.Prove through test of many times, when β is too small, middle bristle (1) tip is meticulous, causes middle bristle 1 integral hardness inadequate, cannot effectively reject out by swill from teeth space; When β is excessive, middle bristle 1 tip is excessively blunt, can not effectively insert in teeth space.
Through test of many times, show that described fur 2 is 4:1 with the number ratio of described middle bristle 1, show that this ratio is the best proportion of fur 2 and middle bristle 1 through test of many times, the effect of rejecting swill in teeth space can be reached, again can teeth surfaces effectively, and reduce the wearing and tearing 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.The effect of such design is because middle bristle 1 is rejected in the process of the swill in teeth crevice, these swills be mostly drop on described middle bristle 1 high-quality green tea at same horizontal plane, the re-entrant angle of the plane that this horizontal plane is formed and described fur 2.This is because the high-quality green tea of middle bristle 1 is at same horizontal plane, the plane that this horizontal plane is formed is a slope, and swill can slip in re-entrant angle along slope.Hard fine, soft fur 1.1 and the similar net plane of the interlaced formation of soft fine, soft fur 1.2 in making, effectively can stop swill in teeth space to fall into re-entrant angle like this and drop to bristle root thereupon.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 be easy to clean up.Such design is also in order to reduce production cost, as everyone knows, 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.
In described between hard fine, soft fur 1.1 apart from one another by being 0.7mm.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 be greater than 0.7mm, soft fine, soft fur 1.2 interval is greater than 1.5mm, and swill cannot be stoped to drop to bristle root.According to scientific experimentation statistics, the diameter of the swill in teeth crevice about 80% is within the scope of 0.73mm-1.35mm.And the swill of length in the teeth crevice of 1.5mm-3.5mm accounts for 80%.Because hard fine, soft fur 1.1 and soft fine, soft fur 1.2 are that interlaced arrangement can stop that most swill falls into the root of bristle.
The high-quality green tea of described middle bristle is at same horizontal plane, and the high-quality green tea of described soft fine, soft fur is at same horizontal plane, and the plane that described in the plan range that the high-quality green tea of middle bristle is formed, the high-quality green tea of soft fine, soft fur 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.Because the diameter of the swill in teeth crevice about 80% is within the scope of 0.73mm-1.35mm.And the swill of length in the teeth crevice of 1.5mm-3.5mm accounts for 80%.So most swill can be made like this to be unlikely to fall into the root of bristle.And can reduce in the process of brushing teeth like this, 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, can extend the service life of toothbrush like this.
In the process of brushing teeth, fur 2 is perpendicular to dental surface, and described soft fine, soft fur 1.2 is vertical with described fur 2.Soft like this fine, soft fur 1.2 is just parallel to dental surface, is similar to the effect of grid, so just can play to greatest extent and stop that the swill in teeth crevice drops in the effect of bristle root.
In hard fine, soft fur 1.1 1 aspect play a part to stop that the swill in teeth crevice drops at bristle root.On the other hand, middle bristle 1 can also be assisted to reject swill 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, can go deep into rejecting more tiny swill in teeth crevice.In described, hard fine, soft fur 1.1 is vertical with described middle bristle 1, just defines similar " √ ", and easier by swill, from teeth space, hook is out.
In order to the angle of the upper surface of the root and head toothbrushes substrate 3 of determining middle bristle 1 is α, the high-quality green 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 getting any value, that brushes teeth is most effective, namely toothbrush can be quicker, easilier rejected from teeth space by swill.Carry out following test.
Embodiment one:
Utilize the tooth model of department of stomatology simulated patient to test, the swill generally can got stuck between the teeth, mostly be the food fiber tissue of filiform.Because the staple of pp cotton has similar attribute to food fiber, it is all such as filiform.So adopt PP cotton simulation food fiber in experiment, the PP cotton of " Huvis " brand is twisted diameter within the scope of 0.73mm-1.35mm, the thin staple of length within the scope of 1.5mm-3.5mm, these thin staples are stuck in the teeth space of tooth model, a thin staple is blocked in each teeth space, because people has 32 teeth (comprising wisdom tooth) altogether, so altogether blocked the thin staple of 32-2=30 root.Utilize these thin staples to simulate the swill in teeth space.Fur 2 is 4:1 with the number ratio of middle bristle 1, and the angle of the root of middle bristle (1) and the upper surface of head toothbrushes substrate 3 is that the angle of α, α gets 30 °, 45 °, 60 °, 75 °, 90 ° respectively.If consider that middle bristle 1 is easy to the mucous membrane of scratch oral cavity wall, causes canker sore if the angle of α is got be less than 30 °, so the angle of α, from 30 °, gets a value every 15 ° in experimental program.
The high-quality green tea of described middle bristle 1 is at same horizontal plane, and the side angle of the plane that this horizontal plane is formed and described fur 2 is that the angle of β, β gets 30 °, 45 °, 60 °, 75 °, 90 ° respectively.When β is less than 30 °, middle bristle 1 tip is meticulous, causes middle bristle 1 integral hardness inadequate, cannot effectively reject out by swill from teeth space; So the angle of α, from 30 °, gets a value every 15 ° in experimental program.
It should be noted that, PP cotton is the noun determining implication.PP is cotton: be commonly called as male earner cotton, hollow cotton, also filling cotton is claimed, material is polypropylene chopped fiber, mainly contain general fibre and hollow two kinds, it is good that this product has resilience, feel is smooth, price is lower, warmth retention property is good, is widely used in the industries such as toy filling, clothes, bedding, gum sprayed cotton and purifier.Therefore PP Gossypium is in clear expression.
