Description

Mechanics toothbrush

1, technical field

This patent belongs to daily living article field, and it can significantly improve the cleanliness factor of brushing teeth, and prevents tooth disease better.

2, background technology

World Health Organization's research proves: its Apoplexy Morbidity of patient suffering from periodontosis can improve 80%; Yin Anna university checks in discovery 242 people has 10 human mouth all to exist " germ of easily bringing out cancer "; Medical circle also finds through statistics the pregnant woman suffering from severe periodontal disease, and productive rate of getting up early exceeds 7 times than healthy pregnant women.Visible brush teeth quality and health closely bound up.

I always conscientiously brushes teeth, and there has also been carious tooth, and this impels me to find the toothbrush research that market is common: although the kind of toothbrush is very abundant, but how much different all toothbrushes all also exist defect:

1) V-type and waveform toothbrush are declared " better laminating tooth cheek labial surface; cleaning effect is good ", but in fact, no matter be according to mathematical probabilities analysis, or the existence general knowledge imagination: when brushing teeth, the tip of this toothbrush hair side just in time coincide the recessed gap of teeth space chance (as accompanying drawing 1-1) very little; If just in time when the boss of tooth cheek labial surface (as accompanying drawing 1-2), then cleaning benefits is poorer, and can damage gum at the tip of V-type bristle; When brushing teeth, most situation is as illustrated in the accompanying drawings from 1 to 3, the tip of bristle neither in teeth space groove, also not in the projection of tooth cheek labial surface, the cleaning benefits that there is no.

2) although soft bristle Anti-dental injury gum, the effect difference (see accompanying drawing 2-3) of tooth is not only cleaned; And the backlash of soft bristle tooth brush is comparatively large, the movement range majority being equivalent to brush teeth is at work " idle work " (see accompanying drawing 4), and two is just poorer because superposing the effect that cleans one's teeth.

3) though the better clean corona face of hard bristle energy, but the gum that easily damage is tender and lovely, bring out periodontitis;

4) brush teeth at the beginning after toothpaste squeezed into by current all toothbrushes, toothpaste will be scattered to the left and right sides because being squeezed, and not on cleaning surface, the nature that is scattered of toothpaste can directly affect the clean effect of brushing teeth.

5) the bristle front end of a lot of toothbrush is " gradually thin soft end slightly " at present, and this structure has protective effect to gum, but can significantly decline to the sweeping forces of corona face spot, and the effect that cleans one's teeth is also poor.

More than do not repeat.

This patent toothbrush is strict with mechanics principle design, and the cleanliness factor of not only brushing teeth is higher, can also protect and gum massage.

3, summary of the invention

The particular design of this patent strictly follows mechanics principle each link, makes each link of brushing teeth in strict conformity with scientific law, thus can promote the degree of cleaning one's teeth of brushing teeth, and useful gum.It is characterized in that: on head toothbrushes, the central part bristle of longitudinal arrangement shortens 2-4 millimeter than the bristle of its periphery, and central part bristle improves 1-2 level than the edge bristles hardness of its periphery, and namely edge bristle is fur, and central part bristle is bristle.

The utility model content comprises following 3 aspects:

1, middle part undercoat improves corona cleaning effect:

Longer by the bristle of the visible toothbrush of accompanying drawing 2-1, will be oblique when brushing teeth.This patent design shortens 2-4 millimeter (accompanying drawing 3-2) the bristles of toothbrush middle part ordinary hard, under the prerequisite that bristles hardness is constant, just equal " resistance arm " after bristle shortens to have shortened, so just tiltedly alleviate, bristles and corona face are closer to vertical, the horizontal force of now bristles cleaning corona face spot just increases (accompanying drawing 2-2), enhances the cleaning action in corona face; Common softer, longer bristles is then easy to oblique in the market, now bristles just reduces for the lateral sweeping forces of spot on corona face, the component on the contrary spot extruded to corona face is larger (accompanying drawing 2-3) but, although Here it is, soft bristle tooth brush does not damage gum, also the reason in not easily clean corona face.And the backlash of soft bristle tooth brush long (accompanying drawing 4), this patent toothbrush significantly improves the effective travel of toothbrush, and cleaning benefits is better.

2, toothbrush both sides fur protection gum, clean teeth space:

Can see from accompanying drawing 3-2, the soft bristle normal bristles long 2-4 millimeter relatively harder than middle part of this patent toothbrush two edges design, thus, when above-below direction scrubs teeth space, a normal bristles edge fur for mid portion plays skeletal support effect, even if the soft bristle at edge keeps certain cleaning dynamics to the cheek labial surface of tooth and tooth break joint, middle harder bristle is made again not contact gum, thus killing three birds with one stone:

1) the cheek labial surface of tooth and tooth break joint clean good;

2) the ordinary hard bristle in the middle of can not damage gum;

3) the soft bristle at edge also has certain massage effect to gum, is conducive to the blood circulation promoting gum.

3, matrix toothbrush face can make toothpaste minimizing be scattered:

After plane toothbrush contacts with corona face (accompanying drawing 3-1), the toothpaste on toothbrush will be extruded and be scattered; And behind the toothbrush contacts corona face of this patent design (accompanying drawing 3-2), extruded toothpaste is gone along with sb. to guard him by longer fur, toothpaste is scattered minimizings, remains in the amount of paste of brushing teeth on cleaning surface so just more, naturally can improve cleaning benefits.

4, accompanying drawing explanation

Accompanying drawing 1-1 is just in time relative with the teeth space coincidence view in the top of V-shape bristle;

Accompanying drawing 1-2 is that the top of V-shape bristle just in time withstands on prominence, tooth cheek labial surface center schematic diagram;

Accompanying drawing 1-3 is that the top most cases of V-shape bristle is difficult to schematic diagram relative to teeth space coincidence;

Accompanying drawing 2-1 is hardness with stressed identical bristle when length is different, the oblique very large schematic diagram of degree difference;

Accompanying drawing 2-2 has larger removing spot force diagram with the subvertical bristles in corona face;

Accompanying drawing 2-3 is that tiltedly serious soft bristle removes spot active force very logotype;

Accompanying drawing 3-1 to be ordinary toothbrush be just easily scattered when brushing teeth and starting toothpaste schematic diagram;

Accompanying drawing 3-2 is that outer rim bristle is longer, and the structure that intermediate bristle is shorter makes the schematic diagram that toothpaste is not easily scattered;

Accompanying drawing 4 is the excessive schematic diagrames of soft bristle tooth brush backlash when brushing teeth.

Each the description of the drawings content above-mentioned is as follows:

Accompanying drawing 1-1:

Teeth space (4) is just in time aimed in " V-type " above bristles (1) protruding (3), under this state, the V-type projection of toothbrush can play better cleaning benefits, but the appearance of the few coincidence of this situation when actual brushing teeth, so cleaning benefits has just become empty concept.

Accompanying drawing 1-2:

The cambered surface top (2) of tooth cheek labial surface is just in time aimed in " V-type " above bristles (1) protruding (3), teeth space more not easy cleaning gum can be injured is made under this state, certainly, when actual brushing teeth, this situation is also more rare.

Accompanying drawing 1-3:

" V-type " above bristles (1) protruding (3) both misalignment teeth spaces (4), also not facing to the cambered surface top (2) of tooth cheek labial surface, V-type toothbrush cleaning benefits under this state is not good, and when actual brushing teeth, this situation accounts for the overwhelming majority.

Accompanying drawing 2-1:

The drawings shows when the dynamics of brushing teeth is identical with bristle stiffness, after bristles shortens, the oblique degree of bristle can alleviate:

Fig. 2-1-1 shows the bristles (2) of the upper certain degree of hardness of head toothbrushes (1), and because it is longer, when brushing teeth, tiltedly degree is very large;

Fig. 2-1-2 shows the bristles (2) of the upper same rigidity of head toothbrushes (1), and because of its contraction in length, when brushing teeth, tiltedly degree is very little;

Accompanying drawing 2-2:

When between bristles (2) and vertical line (1), angle is less, the negative taper of bristles is less, the active force (5) of the upper spot (4) of bristles cleaning corona face (3) is very large, and now to give the active force (6) that spot (4) extrudes to corona face then very little for bristles (2).

Accompanying drawing 2-3:

When between bristles (2) and vertical line (1), angle is larger, the negative taper of bristles is larger, the active force (5) of the upper spot (4) of bristles cleaning corona face (3) is very little, and now to give the active force (6) that spot (4) extrudes to corona face then very large for bristles (2).

Accompanying drawing 3-1:

Visible in this toothbrush schematic cross-sectional view, the power (6) formed that will be squeezed after the toothpaste (3) squeezed in bristles (2) contacts with tooth crown (8) acts on, and can be scattered to both sides.

Accompanying drawing 3-2:

Visible in this toothbrush schematic cross-sectional view, the bristles (4) that middle part is shortened and be distributed between the longer soft bristles (5) in edge and define a groove, the stress (7) that can be subject to edge toothbrush fur inside after the toothpaste (3) squeezed in a groove contacts with dental surface (8) acts on, thus minimizing toothpaste is scattered to both sides.

Accompanying drawing 4:

In the brushing action that head toothbrushes (1) comes and goes continuously in oral cavity, if the bristle of toothbrush is softer or long, so will: when head toothbrushes (1) release forward, as shown in Fig. 4-1, a branch of bristles (5) end rests on the A point in corona face (8), and when after head toothbrushes counter motion (L) distance as shown in the Fig. 4-2: end of this bundle bristles (5) is appointed and is so also rested on the A point in corona face (8), toothbrush has moved and has just changed the tilted direction that falls of bristles (5) apart from (L), but for cleaning teeth crown (8), the not mobile any distance of end of bristles (5), namely the effect of brushing teeth is not played, this long segment distance (L) of head toothbrushes (1) movement has just done idle work.Bristles is more long softer, and lost motion distance when brushing teeth is larger, and feature of the present utility model also significantly can shorten this lost motion distance when brushing teeth, thus improves the secondary effect of clean tooth.

5, detailed description of the invention:

The special construction of this patent has the outstanding effect that cleans one's teeth, but the use of using method and other toothbrushes is just the same, from accompanying drawing 3-2:

First appropriate toothpaste (3) is extruded into above the shorter bristle in toothbrush middle part (4), then corona face (8) is up and down scrubbed according to the longitudinal direction of teeth arrangement, bristles (5) longer in the process can toothpaste (3) and makes it not easily be scattered by pad, and the bristles (4) shortened can with close to the clean corona face better of the angle perpendicular to corona face.After brushing after crown, this patent toothbrush can be used along teeth space direction to scrub the cheek labial surface of upper lower teeth up and down, now, the longer fur (5) of this patent toothbrush outer rim can play again the effect of protection and gum massage.

Claims

1. the principal character of a mechanics toothbrush shows with in the difference of existing toothbrush bristle, it is characterized in that: on head toothbrushes, the central part bristle of longitudinal arrangement shortens 2-4 millimeter than the bristle of its periphery, and central part bristle improves 1-2 level than the edge bristles hardness of its periphery, namely edge bristle is fur, and central part bristle is bristle.
