Description

TOOTHBRUSH WHERE TOOTHBRUSH HAIRS WITH DIFFERENT LENGTH ARE ALTERNATELY DISPOSED}

The present invention relates to a toothbrush in which toothbrushes of different lengths are alternately arranged.

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 in which bristles of different lengths are alternately arranged so that no dental floss is required.

According to an aspect of the present invention, there is provided a toothbrush comprising: a toothbrush; And a toothbrush head having first bristles and second bristles formed on the support. The length of the second bristles is 70% or less of the length of the first bristles. When the first bristles are inserted between the teeth at the inside of the tooth, the first bristles are arranged alternately with the second bristles, Wherein at least one of the first bristles protrudes outwardly through the teeth and the first bristles of the first bristles of the first bristles enter the back of the molar, So that the foreign material between the teeth is hit by the restoring force.

A toothbrush head according to an embodiment of the present invention includes a support portion; And first bristles and second bristles formed on the support. The length of the second bristles is 70% or less of the length of the first bristles. When the first bristles are inserted between the teeth at the inside of the tooth, the first bristles are arranged alternately with the second bristles, Wherein at least one of the first bristles protrudes outwardly through the teeth and the first bristles of the first bristles of the first bristles enter the back of the molar, So that the foreign material between the teeth is hit by the restoring force.

The toothbrush according to the present invention is such that the length of the second bristles is less than 70% of the length of the first bristles, so that the first bristles can be substantially swept away 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 calculus between the teeth and the gums because the length of the second bristles is short, the flavor can be prevented and the gums can be made strong as a result.

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 a floss and which can completely remove foreign matter between teeth and can prevent the taste.

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 bristles that can be substantially swept, and as a result, foreign matter between the teeth can be completely removed, which has been confirmed through actual experiments. 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 second bristles is considerably shorter than the length of the first bristles, the second bristles are not disturbed when the first bristles remove foreign matter between the teeth and the gums. As a result, foreign matters between the teeth and the gums can be removed well using the first bristles, and as a result, no foreign matters exist between the teeth and the gums, and the taste can be prevented. In addition, since the first bristles are swept away, the gums may not be damaged even if they are brushed over the gums.

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.

1 to 3, the toothbrush of this embodiment includes a toothbrush bar 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 120a, 120b, 120c and 120d and second bristles 122.

The first bristles 120 are bristles having a relatively long length, and may be installed in the support 110. For example, the first bristles 120 may be inserted and fixed in the holes of the support 110.

The first bristles 120a and 120d are terminal bristles in the longitudinal direction of the toothbrush head 102, and the first bristles 120b and 120c are remaining first bristles except for the terminal first bristles 120a and 120d. . The first bristles 120a, 120b, 120c and 120d may have the same or similar length as the bristles of a general toothbrush.

According to one embodiment, the outermost first bristles 120a and 120d may have a long length and then the bristles 120b and 120c may have a short length. In this case, however, there may be only one first bristles 120a and 120d, so it may be difficult to maintain the force when functioning as the floss. Therefore, it is efficient for the terminating first bristles 120a and 120d and the subsequent bristles 120b and 120c to have a long length so that they can brush with sufficient force. However, if the number of the terminal first bristles 120a and 120d is three or more, respectively, the next bristles may have a short length. Of course, in consideration of molar teeth, it is preferable that the terminal first bristles 120a and 120d are two or less so as to be easily inserted in the molar direction of the toothbrush.

The second bristles 122 are alternately arranged with the first bristles 120b, as shown in FIGS. 1 and 2, and may have a length smaller than that of the general bristles. As a result, the first long bristles 120 and the second long bristles 122 may be alternately arranged.

That is, in the toothbrush of the present invention, the second bristles 122 may have a length smaller than the first bristles 120. The reason why the length of the second bristles 122 is smaller than the length of the first bristles 120 is to allow the first bristles 120 to be wiped while cleaning the teeth.

According to one embodiment, the length h2 of the second bristles 122 may be about 70% or less of the length h1 of the first bristles 120, preferably 50% or less, optimally 42% It may be

When the length h2 of the second bristles 122 exceeds 70% of the length h1 of the first bristles 120, even when the first bristles 120 are wiped off during brushing, the foreign matter between the teeth is sufficiently removed. Was 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 bristle 122 is about 70% to 50% of the length h1 of the first bristle 120, the length h2 of the second bristle 122 is the first bristle ( Compared to when it is about 50% or less of the length h1 of 120, the effect of sweeping or digging between teeth or between teeth and gums may be inferior, but the length h2 of the second bristles 122 is equal to the first bristles 120. Compared to more than 70% of the length (h1) of the), the effect is higher and the foreign matter can be sufficiently 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 sweep or dig between the teeth or between the teeth and the gums. The 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, the long first bristles 120 sweep the teeth in a state in which the second bristles 122 do not touch the tooth surface during tooth brushing. 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.

In addition, since the length of the second bristle 122 is considerably shorter than the length of the first bristle 120, the second bristle 122 can be inserted from the inner side of the tooth to the outer side as shown in FIG. In this case, the second bristles 122 may penetrate 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. 3, the first bristle 120 and the second bristle 122 may have the same width, but are not limited thereto.

However, in order to maximize the writing effect of the first bristles 120, the first bristle 120 is made of soft brushes or microfiber brushes, while the second bristle 122 is made of stronger brushes than the first bristle 120. Can be done. That is, the strength of the second bristles 122 may be higher than the strength of the first bristles 120.

In addition, in order to maximize the writing effect, the first bristles 120 have a length smaller than the first brushes 300 and the first brushes 300 having a triangular shape as shown in FIG. 5. It may be a double parent consisting of (302).

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 bristle 122 may be 0.5 cm.

In summary, implementing the length of the second bristle 122 to 70% or less, preferably 50% or less of the length of the first bristle 120 is effective in removing foreign matter between teeth and foreign matter between teeth and gums. to be.

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.

For example, as described below, the second bristle 122 may be replaced with an empty space, and some short bristle or empty space may be arranged between the first bristle 120.

Hereinafter, the operation of the toothbrush during brushing will be described with reference to FIGS. 6, 7 and 18.

When using an existing toothbrush, the bristles move as shown in Fig. 6C. 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 can not remove 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, the conventional toothbrush is not inserted into the bristles into the space 610 between the teeth and gums as shown in Figure 6 (D) and (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 Figure 6 (A) when brushing the first brush bristles 120 is bent to use the tooth 600.

Specifically, the first bristles 120-1, which were bent at the time of brushing, hit the foreign matter between the teeth with great restoring force as the toothbrush moves, or the first bristles 120-2 are inserted into the interdental spaces. Foreign matter between the teeth is removed by jumping outward or pushing inward. That is, the toothbrush of the present invention is suitable for brushing a tooth which is complicated and has severe irregular bending.

According to one embodiment, since the length of the second bristle 122 is considerably shorter than the length of the first bristle 120, the first bristle 120 is bent as shown in FIG. 6B, In particular, it may bend at 30 degrees or more (α), 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.

On the other hand, since the length of the first bristle 120 is considerably longer than the second bristle 122, the second bristle 122 does not interfere with the writing operation of the first bristle 120 when brushing, thus the first bristle. Foreign matter between the tooth 600 and the gum 602 610 by the 120 can be easily removed. Specifically, as shown in FIG. 6F, the first bristles 120 may be bent and inserted between the teeth 600 and the gums 602 610, and as a result, the teeth 600 and Foreign matter between the gums 602 may be removed 610. That is, one region C of the areas where the teeth are concentrated by the first bristles 120 may be 610 between the teeth 600 and the gums 602 as shown in FIG. 7A. . Therefore, foreign matter between the tooth 600 and the gum 602 610 can be removed well, as a result can be prevented.

In particular, even when the first bristles 120 directly touch the gums, the first bristles 120 are swept away and the gums are massaged while brushing the teeth, so that the gums can be strengthened without hurting 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 length of the outermost first bristles 120 is long, foreign matter near the gum 602 having a small space in the space between the teeth can be easily removed.

In the case of the horizontal brushing, the first bristles 120 dig in between the teeth and the gums 602 to remove foreign matter between the teeth and the gums 602, and the first bristle is long in both the horizontal and longitudinal brushings. The field 120 penetrates between the teeth and strikes the foreign matter between the teeth, so the effect of removing the foreign matter between the teeth is excellent.

On the other hand, the dentist does not recommend brushing in the horizontal direction, because the tooth surface is worn out in the horizontal brushing with a conventional toothbrush. However, since the toothbrush of the present invention does not contact the tooth surface of the short second bristles 122, that is, only the long first bristles 120 touch the tooth surface, the tooth surface is scarcely worn out even when the tooth brush is transversely brushed. Therefore, lateral tooth brushing can also be possible.

According to one embodiment, since the second bristles 122 are considerably shorter than the first bristles 120, inserting the second bristles 122 between the teeth from the inside of the teeth, as shown in FIG. The second bristles 122 may 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.

On the other hand, due to the short second bristles 122, three-sided tooth brushing (tooth top, medial and lateral tooth brushing) of the tooth may be possible at one time. It is impossible with existing toothbrushes.

In addition, when the toothbrush is pushed in the molar 600a direction in a three-sided brushing state, the first bristles at the ends of the first bristles 120 as shown in FIGS. 7D and 18C are removed. It may be possible to enter the rear side (inside) of the molar (600a) may be able to brush the back of the molar (600a). Therefore, it is possible to brush the wisdom tooth. Of course, the toothbrush of the present invention can brush teeth around the molar 600a as well as the rear side of the molar 600a. 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.

To summarize, the toothbrush of the present invention can perform lateral tooth brushing, longitudinal brush brushing, trichotomous brushing, molar brushing, and flossing. 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, the use of the toothbrush of the present invention can substantially improve the probability of tooth decay because the foreign substance is almost completely removed. 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.

Looking at the toothbrush cleaning, since the length of the second bristles 122 inside the first bristles 120 is short, even if foreign matters and toothpaste are placed on the second bristles 122 after brushing, the foreign bodies and toothpastes can be easily removed with water. Can be. 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.

According to one embodiment, unlike general powered toothbrushes with other bristles inside the outermost bristles, in the toothbrush of this embodiment no bristles are present in the inner space e of the bristles 820 and 822. 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.

According to another embodiment, the second bristles 822 may have a length of 70% or less, preferably 50% or less of the length of the first bristles 820.

In this case, when the support 810 rotates, the first bristles 820 sweep the teeth. In particular, since the first bristles 820 are considerably bent and bent, the foreign materials between the teeth are hit or inserted into the teeth to push the foreign materials, thereby completely removing the foreign materials between the teeth. In this case, the second bristles 122 may not interfere with the writing operation of the first bristles 820.

According to another embodiment, the first bristles 820 and the second bristles 822 are arranged at the outermost and third bristles are arranged inward, wherein the third bristles are the length of the first bristles 820. It can have a length of up to 70%.
