Description

Toothbrush with different length of bristles {TOOTHBRUSH INCLUDING TOOTHBRUSH HAIRS WITH DIFFERENT LENGTH}

The present invention relates to a toothbrush having toothbrushes of different lengths.

Generally, the bristles of the toothbrush have the same or similar length. In this case, a foreign body placed between the teeth can be removed to some extent, but foreign substances tightly caught between the teeth are hardly removed. That is, it is difficult to completely remove foreign matter.

In addition, the toothbrush is because the inner bristles interfere with the operation of the outer bristles, it is not possible to remove the tartar generated in the space between the teeth and gums, there is a high probability of appearance.

As a result, dental floss should be used separately, and prevention of tooth decay is difficult even if tooth brushing is done, and therefore expensive dental treatment must be frequently received due to tooth decay.

Moreover, foreign matter and toothpaste are often caught between the bristles after brushing, and even if the toothbrush is washed with water, these foreign substances and toothpaste are not removed well. As a result, the toothbrush becomes contaminated over time and, as a result, the use of contaminated toothbrushes could damage the gums.

The present invention provides a toothbrush having bristles of different lengths so that no dental floss is required.

In order to achieve the object as described above, the toothbrush according to an embodiment of the present invention toothbrush bar; And a toothbrush head having first bristles and second bristles formed on the support. Wherein the second bristles are bristles on the inside of the first bristles, the first bristles are outermost bristles, the length of the second bristles is less than 70% of the length of the first bristles, At least one of the first bristles protrudes to the outside through the teeth, and the first bristles at the end of the first bristles enter the back of the molar, The first bristles are inserted between the tooth and the gum to remove foreign matter between the tooth and the gum, and the first bristles can wrap the top, the inside, and the outside of the tooth all at once.

Toothbrush head according to an embodiment of the present invention support; And first bristles and second bristles formed on the support. Wherein the second bristles are bristles on the inside of the first bristles, the first bristles are outermost bristles, the length of the second bristles is less than 70% of the length of the first bristles, At least one of the first bristles protrudes to the outside through the teeth, and the first bristles at the end of the first bristles enter the back of the molar, The first bristles are inserted between the tooth and the gum to remove foreign matter between the tooth and the gum, and the first bristles can wrap the top, the inside, and the outside of the tooth all at once.

In the toothbrush according to the present invention, the length of the second bristles is 70% or less of the length of the first bristles, and as a result, the first bristles can be substantially wiped out when brushing teeth. Specifically, the first bristles are bent at the time of brushing, and then the first bristles are pushed against the foreign substances between the teeth with the bent force, or inserted between the teeth to remove foreign matter. Therefore, toothbrushing does not leave any foreign matter on the tooth, so effective tooth decay prevention is possible.

In addition, since the first bristles can easily remove foreign substances between the teeth and the gums because the length of the second bristles is short, no tartar is formed between the teeth and the gums, and the taste can be prevented. .

In addition, since the length of the second bristles is short, it is possible to easily remove the foreign matter and toothpaste inserted between the bristles after tooth brushing. As a result, contamination of the toothbrush can be minimized.

The present invention relates to a toothbrush which does not need dental floss and can completely remove foreign substances caught between teeth and prevent the appearance.

Existing toothbrushes that advertise that they do not need floss do remove some foreign material between the teeth, but there is a lot of foreign matter between the teeth even after tooth brushing.

Further, since the bristles have the same length, the bristles are not wiped off because the bristles are disturbed by the surrounding bristles, so that foreign matter between the teeth and the gums can hardly be removed. As a result, foreign matter remains between the teeth and gums, resulting in weakness of the gums.

In addition, even if the toothbrush is washed with water after brushing, infiltrated foreign matter and toothpaste that have accumulated on the bottom of the toothbrush head are penetrated through the bristles, and the toothpaste is hardly removed. As a result, the toothbrush itself is susceptible to contamination and continued use of the toothbrush can adversely affect the teeth and gums.

On the other hand, the toothbrush of the present invention has a bristles that can be wiped substantially, as a result can completely remove the foreign matter between the teeth, which was confirmed through the actual experiment. Particularly, the toothbrush can remove foreign substances strongly stuck between the teeth. As a result, no floss is needed and there is no need to use an interdental toothbrush separately.

In addition, since the length of the bristles on the inside is much shorter than the length of the outermost bristles, the bristles on the inside are not disturbed when the outermost bristles remove foreign substances between the teeth and the gums. As a result, the outermost bristles can be used to remove foreign matter between the teeth and the gums, and as a result, no foreign matter remains between the teeth and the gums, so that the taste can be prevented. In addition, since the outermost bristles are swept away, even if brushing over the gums, the gums may not be scratched.

In addition, if the toothbrush itself is cleaned after tooth brushing, the length of some bristles is considerably short, so that foreign matter and toothpaste that have penetrated through the bristles are almost completely removed, and contamination of the toothbrush itself can be prevented.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to Figures 1 and 2, the toothbrush of the present embodiment includes a toothbrush 100 and a toothbrush head 102. The shape of the toothbrush holder 100 is not limited to the structure of FIG. 1, and may be variously modified, and a conventional toothbrush holder may be employed.

The toothbrush head 102 includes a support 110, first bristles 120, and second bristles 122.

The first bristles 120 may have an elliptical shape, for example, and may be mounted on the support 110. For example, the first bristles 120 may be inserted and fixed in the holes of the support 110.

According to one embodiment, the first bristles 120 are the outermost bristles, and may have the same or similar length as the bristles of a conventional toothbrush.

The second bristles 122 are bristles located within the first bristles 120 and may have a length less than the bristles of a conventional toothbrush.

That is, in the toothbrush of the present invention, the second bristles 122 which are internal bristles may have a length smaller than the first bristles 120 which are located at the outermost part. The length of the second bristles 122 is smaller than the length of the first bristles 120 in order to operate the first bristles 120 located at the outermost position during brushing to sweep away with a large restoring force to be.

According to one embodiment, the length h2 of the second bristles 122 can be about 70% or less, preferably 50% or less, and most preferably 42% or less of the length h1 of the first bristles 120. [ ≪ / RTI >

If the length h2 of the second bristles 122 exceeds 70% of the length h1 of the first bristles 120, even if the first bristles 120 are wiped out, foreign matter between the teeth can be sufficiently removed Is difficult. This is because the first bristles 120 can not strike foreign objects between teeth with sufficient restoring force (elastic force) and the first bristles 120 can not be inserted properly into the space between the teeth.

Of course, when the length h2 of the second bristles 122 is about 70% to 50% of the length h1 of the first bristles 120, the length h2 of the second bristles 122 is greater than the length h2 of the first bristles 120 The length h2 of the second bristles 122 may be less than the length h2 of the first bristles 120 when the length of the second bristles 122 is less than about 50% of the length h1 of the first bristles 120. However, , The effect is higher than that when the length h1 is more than 70% of the length h1, and a sufficient degree of foreign matter can be removed.

If the length h2 of the second bristles 122 exceeds 70% of the length h1 of the first bristles 120, the first bristles 120 may be used to sweep the teeth or to move between the teeth or between the teeth and gums The padding effect is practically insignificant. That is, toothbrushes that all have the same length or have a slight difference in length do not operate to substantially sweep away. As a result, foreign matter between the teeth can not be sufficiently removed, and it is practically impossible to remove foreign matter between the strongly-wetted teeth.

On the other hand, if the length h2 of the second bristles 122 is 70% or less, preferably 50% or less of the length h1 of the first bristles 120, the first bristles 120 So that the foreign matter between the teeth can be almost completely removed. Specifically, when brushing, the second bristles 122 do not touch the tooth surface so that the first long bristles 120 sweep the teeth. As a result, the bent first bristle 120 has a high restoring force to hit the foreign matter between the teeth can be sufficiently removed foreign matter between the teeth.

Further, since the length of the second bristles 122 is considerably shorter than the length of the first bristles 120, the second bristles 122 are inserted from the inside to the outside of the tooth as shown in Fig. 15 (A) The second bristles 122 can penetrate through the teeth. As a result, the second bristles 122 can function as a dental floss, thus eliminating the need for a separate floss or interdental toothbrush.

The operation of such a toothbrush will be described after further study of the structure of the toothbrush.

Referring to FIG. 2, the first bristles 120 and the second bristles 122 may have the same width, but are not limited thereto.

In order to maximize the effect of the first bristles 120, the first bristles 120 are made of soft bristles or microfibers, while the second bristles 122 are made of stronger bristles than the first bristles 120, The strength of the second bristles 122 may be higher than the strength of the first bristles 120. [

In order to maximize the writing effect, the first bristles 120 include first bristles 300 having a triangular end shape and second bristles 300 having a smaller length than the first bristles 300, (302). ≪ / RTI >

According to one embodiment, the second bristles 122 may have a length of less than or equal to about 42% of the length of the first bristles 300 of the first bristles 120, And may have a length of 50% or less. For example, the first brush 300 may be 1.2 cm, the second brush 302 may be 1 cm, and the second bristles 120 may be 0.5 cm.

Looking at the overall arrangement of the bristles, up to five or more bristles may be arranged in the width direction of the toothbrush head 102, as shown in FIG. In the case of a general toothbrush, four bristles are arranged vertically. The arrangement of one or more bristles more than the conventional toothbrush further increases the effect of the first bristles 120 when the space of the second bristles 122 is wider and facilitates removal of foreign matter between the teeth and the gums Because.

On the other hand, although only the outermost first bristles 122 are long, the length of the bristles just inside the outermost periphery may be long. In this case, although it has the effect of being used, it is remarkably reduced, and therefore, the effect of removing the foreign matter between the teeth may be deteriorated.

In addition, although the bristles on the outer side are shortened and the bristles on the inner side are long, the area of the bristles to be wiped is small, and the removal efficiency of the foreign substance is lowered and the removal efficiency of the foreign material between the teeth and the gum is lowered do.

The total length of the second bristles 122 within the first bristles 120 may be less than or equal to 50% of the length of the first bristles 120 in the outermost Is effective in removing foreign substances between the teeth.

According to another embodiment, the inner second bristles have a length of less than about 70% of the first outermost bristles, and the outer bristles, in particular the outermost bristles, may be arranged in addition to the first bristles. The third bristles may have a length of 70% or less, preferably 50% or less of the length of the first bristles. The third bristles may have a circular, elliptical, or rectangular shape with the first bristles and may alternate with the first bristles Lt; / RTI > That is, the first bristles and the third bristles having different lengths may be alternately arranged at the outermost periphery. In this case, the writing effect of the first bristles can be further increased. Meanwhile, the third bristles may have the same length as the second bristles or may have different lengths.

In short, in the toothbrush of this embodiment, short bristles are arranged inside or outside the long bristles, and the length of the short bristles may be less than about 70% of the length of the long bristles for a writing effect.

In another aspect, the bristles adjacent to the long bristles may have short lengths to maximize the writing effect. For example, at least one, preferably all, of the neighboring bristles in the north, south, east, and south directions relative to the long bristles may have a short length. That is, as long as the bristles adjacent to the long bristles have a length of about 70% or less of the length of the bristles, the structure of the bristles can be variously modified.

In yet another aspect, the void space may be arranged without short bristles arranged between the long bristles. That is, short bristles can be replaced by empty spaces. As a result, the writing effect can be maximized. A detailed description thereof will be described later.

Hereinafter, the operation of the toothbrush during tooth brushing will be described with reference to FIGS. 5, 6, and 15. FIG.

When an existing toothbrush is used, the bristles move as shown in Fig. 5 (C) when brushing the toothbrush. That is, due to the inner bristles, the bristles do not sweep the teeth or are hardly inserted into the space between the teeth. As a result, the toothbrush could not remove the foreign matter between the teeth well. Particularly, the toothbrush can hardly remove foreign substances tightly caught between the teeth. Overall, existing toothbrushes can only clean simple planes, making them unsuitable for brushing teeth that are complex and severely curved.

In addition, in the conventional toothbrush, the bristles can not be inserted into the space 510 between the teeth and the gums as shown in FIGS. 5 (D) and 5 (E). As a result, existing toothbrushes can not substantially brush between tooth and gum.

On the other hand, in the case of the toothbrush of the present invention, as shown in (A) of FIG. 5, the first bristles 120 are bent to use the tooth 500.

Specifically, the first bristles 120a bent at the time of toothbrushing have a large restoring force to hit the foreign matter between the teeth with the movement of the toothbrush, or the first bristles 120b are inserted into the space between the teeth. As a result, foreign substances between the teeth are protruded to the outside of the teeth and removed or pushed inward. That is, the toothbrush of the present invention is suitable for brushing teeth with complicated and uneven curves.

According to one embodiment, since the length of the second bristles 122 is significantly shorter than the length of the first bristles 120, the first bristles 120 are bent as shown in Figure 5 (B) Particularly, more than 30 degrees (?), For example, 70 degrees or more. That is, at least one of the first bristles 120 is warped by more than 70 degrees when brushing, and as a result, the first bristles 120 hit the foreign material between teeth with the bent force (restoring force) as the toothbrush moves I dig in between the teeth. It is a structure that is not possible with conventional toothbrushes in which the bristles have the same or nearly similar length.

5 (F) and FIG. 15 (B), when the second bristles 122 are opened, the teeth 500 and the bristles And digs into the gums (502). As a result, the foreign matter trapped between the tooth 500 and the gum 502 can be removed, so that the taste can be prevented. The dentist does not recommend brushing in the lateral direction because the tooth surface is worn out when the toothbrush is brushed in the lateral direction. However, in the toothbrush of the present invention, since the second short bristle 122 does not touch the tooth surface, that is, only the long first bristle 120 touches the tooth surface, the tooth surface is hardly worn even when transversely brushed. Therefore, lateral tooth brushing can also be possible.

In addition, even if the first bristles 120 directly contact the gum area C, since the first bristles 120 massage the gums while brushing the teeth, scratches do not occur on the gums. In other words, the toothbrush of the present invention can also brush teeth while massaging the gums. On the other hand, in the conventional toothbrush, since the bristles touch the gums without bending, it is easy to damage the gums.

In addition, since the first bristles 120 of the outermost tooth are long, foreign substances in the vicinity of the gum 502 having a small space in the inter-tooth space can be easily removed.

The first bristles 120 pierce between the teeth and the gums 502 in the case of the transversely bristles, and are excellent in removing foreign substances between the teeth and the gums 502. In the case of transverse bristles, The first bristles 120 having long teeth in both the direction brushing teeth and the brushing teeth in the longitudinal direction make a break between the teeth and strike a foreign body between the teeth, so that the effect of removing foreign matter between the teeth is excellent.

According to one embodiment, since the second bristles 122 are considerably shorter than the first bristles 120, when the second bristles 122 are inserted into the teeth from the inside of the teeth as shown in Fig. 15 (A) The second bristles 122 can penetrate between the teeth. That is, the second bristles 122 perform a dental function, and as a result, foreign matter in the interdental spaces can be easily and reliably removed without separately using a toothbrush or an interdental toothbrush. In addition, it can have the same effect as that obtained by scaling only with brushing.

Since the second bristles 122 arranged in the center are formed to have a middle structure as the length of the second bristles 122 is considerably shorter than that of the first bristles 120, The teeth 500 may be wrapped as shown. As a result, three tooth follicles (teeth upper, inner and outer flank teeth) of the tooth 500 may be possible at a time. It is impossible with existing toothbrushes.

6 (D) and 15 (C), when the toothbrush is pushed in the direction of the molar teeth 500a in the three-tooth furrow state, the first bristles at the ends of the first bristles 120 It is possible to enter the rear side (inside) of the molar teeth 500a, so that it is possible to brush the teeth on the back side of the molar teeth 500a. Therefore, it is possible to brush the wisdom tooth. Of course, the toothbrush of the present invention is also possible to brush teeth around the molar (500a) as well as the back of the molar (500a). On the other hand, existing toothbrushes are not only incapable of toothbrushing on three sides, but even when the toothbrush is inserted in the molar direction, the bristles can not enter the rear side of the molar teeth, and toothbrushing on the back side is impossible.

In summary, the toothbrush of the present invention can perform the function of transverse brushing, longitudinal brushing, three-sided brushing, molar brushing, dental floss. That is, the toothbrush is an all-in-one toothbrush capable of performing various functions.

Generally, tooth decay occurs because foreign substances are not properly removed. When using a general toothbrush, foreign substances remain in the tooth and the toothbrush itself acts as a pollutant, so the probability of caries is high. Therefore, even if toothbrushing is performed a lot, tooth decay easily occurs and expensive dental treatment is required, resulting in a high cost for dental treatment.

On the other hand, since the use of the toothbrush of the present invention is almost completely removed, it is possible to innovatively improve the probability of tooth decay. In other words, even if the toothbrush is well-dressed, it can prevent tooth decay, reducing the number of dental treatments and significantly reducing the cost of dental treatment.

On the other hand, although not mentioned above, the toothbrush head and the toothbrush handle may be detachable. Therefore, the toothbrush can be used by replacing only the toothbrush head if necessary.

In the toothbrush cleaning, since the length of the second bristles 122 on the inside of the first bristles 120 is short, even if foreign substances and toothpaste are placed on the second bristles 122, foreign matter and toothpaste can be easily removed with water There is a number. That is, the toothbrush can be hygienically managed even if it is toothbrushing.

On the other hand, in the conventional toothbrush, even if the toothbrush is washed, much foreign matter and toothpaste are left between the bristles, and such foreign matter and toothpaste are not removed well. As a result, it is quite unsanitary and causes gums.

7 is a view schematically showing the shape of the second bristles according to another embodiment of the present invention.

Referring to FIG. 7, the second bristles 122a, 122b, and 122c having a length of less than about 70% of the first bristle may have different lengths, for example, 122a, 122b and 122c may be arranged.

According to one embodiment, the curvature of the curve C may be the same as or similar to the curvature of the tooth. As a result, the second bristles can wrap the teeth more closely when brushing teeth.

On the other hand, it is preferable that the length of the second bristles 122a having the longest length among the second bristles 122a, 122b, and 122c is 70% or less of the length of the first bristles.

8 is a view showing a toothbrush according to another embodiment of the present invention.

8, the toothbrush of this embodiment includes a toothbrush 800, a support 810, and bristles 820. As shown in FIG.

According to one embodiment, the toothbrush may be a powered toothbrush, and the support 810 and the toothbrush 800 may have a detachable structure.

For example, a female screw may be formed on the upper end of the toothbrush holder 800, and a male screw may be formed on a part of the support 810 to separate the toothbrush holder 800 and the support 810 from each other. Of course, the support portion 810 can be rotated by the motor.

As another example, the support portion 810 may be rotatably coupled to the toothbrush 800 manually, even if not electrically powered. Various techniques exist for this combination method, and any technique is applicable.

The bristles 820 may be arranged in a circular, elliptical or rectangular shape as shown in Fig. Here, the bristles 820 may correspond to the outermost bristles of a conventional powered toothbrush.

According to one embodiment, there is no bristles in the inner space e of the bristles 820 in the toothbrush of the present embodiment, unlike a general powered toothbrush in which there are other bristles within the outermost bristles. This is because the supporting portion 810 rotates as shown in Fig. 8 when brushing the tooth, so that good brushing is possible even without bristles inside.

As in the previous embodiments, the bristles 820 sweep teeth as the supporting portion 810 rotates. Particularly, since the bristles 820 are significantly bent and hit the foreign material between the teeth with the bent force or inserted between the teeth to push the foreign matter, the foreign matter between the teeth can be completely removed.
