Description

Toothbrush heads with different lengths are alternately arranged {TOOTHBRUSH WHERE TOOTHBRUSH HAIRS WITH DIFFERENT LENGTH ARE ALTERNATELY DISPOSED}

The present invention relates to a toothbrush in which bristles having different lengths are alternately arranged.

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

In addition, since the inner bristles of the toothbrush interfere with the operation of the outer bristles, it is not possible to remove calculus formed in the space between the teeth and gums, so there is a high probability of tooth decay.

As a result, it was necessary to separately use floss, etc., and it was difficult to prevent tooth decay even if brushing teeth, and therefore, expensive dental treatment was often required due to tooth decay.

In addition, foreign substances and toothpaste are often caught between bristles after brushing teeth, and even if the toothbrush is washed with water, these foreign substances and toothpaste are not well removed. As a result, the toothbrush becomes contaminated over time, and thus the gums and the like may be damaged as the contaminated toothbrush is used.

The present invention is to provide a toothbrush in which bristles of different lengths are alternately arranged so that flossing is not required.

In order to achieve the above object, a toothbrush according to an embodiment of the present invention includes a toothbrush holder; and a toothbrush head having a support connected to the toothbrush handle, and first bristles and second bristles formed on the support. Here, the first bristles and the second bristles are alternately arranged, the length of the second bristles is 70% or less of the length of the first bristles, and when the first bristles are inserted between the teeth from the inside of the teeth, the At least one of the first bristles penetrates between the teeth and protrudes to the outside, the first bristle of the terminal part of the first bristles enters the rear side of the molar, and at least one of the first bristles rotates 70 degrees during brushing. The foreign matter is removed by hitting the foreign matter between the teeth with a restoring force after being abnormally bent.

Toothbrush head according to an embodiment of the present invention includes a support; and first bristles and second bristles formed on the support portion. Here, the first bristles and the second bristles are alternately arranged, the length of the second bristles is 70% or less of the length of the first bristles, and when the first bristles are inserted between the teeth from the inside of the teeth, the At least one of the first bristles penetrates between the teeth and protrudes to the outside, the first bristle of the terminal part of the first bristles enters the rear side of the molar, and at least one of the first bristles rotates 70 degrees during brushing. The foreign matter is removed by hitting the foreign matter between the teeth with a restoring force after being abnormally bent.

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 swept during tooth brushing. Specifically, when brushing teeth, the first bristles are bent, and then with a bent force, the first bristles strike foreign substances between the teeth or are inserted between the teeth to remove foreign substances. Therefore, if you brush your teeth, foreign matter does not remain on your teeth, and therefore, it is possible to effectively prevent tooth decay.

In addition, since the length of the second bristles is short, the first bristles can easily remove calculus between the teeth and gums, preventing tooth decay, and as a result, the gums can be strengthened.

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

The present invention relates to a toothbrush that does not require dental floss, completely removes foreign substances caught between teeth, and can prevent dental plaque.

Existing toothbrushes advertised as not requiring dental floss remove some foreign substances between the teeth, but many foreign substances remain between the teeth even after brushing.

Also, since the bristles have the same length, the bristles are not swept because the bristles are obstructed by neighboring bristles, so that little debris between the teeth and gums can be removed. As a result, foreign substances remain between the teeth and the gums, resulting in cavities, and as a result, the gums become weak.

In addition, even if the toothbrush is washed with water after brushing the teeth, foreign substances and toothpaste that have penetrated between the bristles and accumulated on the bottom of the toothbrush head are hardly removed. As a result, the toothbrush itself is easily contaminated, and continuous use of the toothbrush may adversely affect teeth and gums.

On the other hand, the toothbrush of the present invention has bristles that can be substantially swept, and as a result, it is possible to completely remove foreign substances between teeth, which was confirmed through actual experiments. In particular, the toothbrush can remove foreign substances strongly stuck between teeth. As a result, there is no need to floss and use a separate interdental brush.

Also, because the length of the second bristle is significantly shorter than the length of the first bristle, the second bristle does not get in the way when the first bristle removes debris between teeth and gums. As a result, it is possible to well remove foreign matter between the teeth and the gums using the first bristle, and as a result, there is no foreign matter between the teeth and the gums, so that cavities can be prevented. In addition, since the first bristles are swept, wounds on the gums may not occur even if brushing teeth over the gums.

In addition, if the toothbrush itself is washed after brushing teeth, the length of some bristles is quite short, so foreign substances and toothpaste penetrating between 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 is a perspective view showing a toothbrush according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing a toothbrush according to an embodiment of the present invention, Figure 3 shows a toothbrush according to an embodiment of the present invention It is a flat view. 4 is a view showing a comparative structure of a first bristle and a second bristle according to an embodiment of the present invention, and FIG. 5 is a view showing the shape of a first bristle according to an embodiment of the present invention, 6 and 7 are diagrams showing a foreign matter removal process using an existing toothbrush and the toothbrush of the present invention. 18 is a diagram showing the function of the toothbrush of the present invention.

1 to 3, the toothbrush of this embodiment includes a toothbrush handle 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 an existing toothbrush holder may be employed.

Toothbrush head 102 includes a support 110 , first bristles 120a , 120b , 120c and 120d and second bristles 122 .

The first bristles 120 are relatively long bristles, and may be installed on the support part 110 . For example, the first bristles 120 may be inserted into and fixed to holes of the support part 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 the 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 lengths as bristles of a general toothbrush.

According to one embodiment, the outermost first bristles 120a and 120d may have long lengths and the next bristles 120b and 120c may have short lengths. However, in this case, since only one of the first bristles 120a and 120d is missing, it may be difficult to maintain force when flossing. Therefore, it is effective for both the terminal first bristles 120a and 120d and the subsequent bristles 120b and 120c to have long lengths, so that brushing can be performed with sufficient force. However, if the number of terminal first bristles 120a and 120d is 3 or more, the next bristles may have a short length. Of course, considering brushing of the molars, it is preferable that the number of terminal first bristles 120a and 120d is two or less so that the toothbrush can be easily inserted in the direction of the molars.

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

That is, in the toothbrush of the present invention, the second bristles 122 may have a shorter length 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 brush teeth while the first bristles 120 are substantially swept during brushing.

According to one embodiment, the length h2 of the second bristle 122 may be less than or equal to about 70% of the length h1 of the first bristle 120, preferably less than 50%, and optimally less than 42%. may be below.

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 swept during brushing, sufficiently remove foreign substances between teeth It was difficult. This is because the first bristles 120 cannot hit foreign substances between the teeth with sufficient restoring force (elasticity) and the first bristles 120 cannot be properly inserted 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 ( Although the effect of sweeping or digging between teeth or between teeth and gums may be reduced compared to when the length (h1) of 120) is less than about 50%, the length (h2) of the second bristles 122 is the first bristles 120 ), the effect is higher than when it exceeds 70% of the length h1, and foreign substances can be sufficiently removed.

When the length h2 of the second bristle 122 exceeds 70% of the length h1 of the first bristle 120, the first bristle 120 sweeps or penetrates between teeth or between teeth and gums. effect is practically negligible. That is, a toothbrush having bristles having the same length or a slight difference in length does not operate to substantially sweep. As a result, it is not possible to sufficiently remove the foreign matter between the teeth, and in particular, it is almost impossible to remove the foreign matter between the strongly jammed teeth.

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

In addition, since the length of the second bristle 122 is considerably shorter than the length of the first bristle 120, the first bristle 120 can be inserted from the inside of the tooth to the outside as shown in (A) of FIG. In this case, the first bristles 120 may penetrate the teeth. As a result, the first bristles 120 can function as dental floss, and thus there is no need to use a separate dental floss or interdental brush.

The operation of the toothbrush will be described in detail after further examining the structure of the toothbrush.

Referring to FIG. 3 , the first bristles 120 and the second bristles 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 bristles 120 are made of soft brushes or microfiber brushes, while the second bristles 122 are made of stronger brushes than the first bristles 120. It can be done. That is, the strength of the second bristles 122 may be higher than that of the first bristles 120 .

In addition, in order to maximize the writing effect, the first bristles 120 are the first brushes 300 having triangular ends and the second brushes having a shorter length than the first brushes 300, as shown in FIG. (302).

According to one embodiment, the second bristle 122 may have a length of about 42% or less of the length of the first brush 300 of the first bristle 120, and about the length of the second brush 302 It 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 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 substances between teeth and between teeth and gums. am.

In another aspect, bristles adjacent to long bristles may have short lengths in order to maximize the writing effect. For example, at least one, preferably all, of the bristles adjacent to each other in the east, west, south, and north directions based on 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 long bristles, the structure of the bristles may be modified in various ways.

In another aspect, there may be an empty space between the long bristles without short bristles being arranged. In other words, an empty space can replace short bristles. As a result, the writing effect can be maximized.

For example, as will be described later, the second bristles 122 may be replaced with empty spaces, and some short bristles or empty spaces may be arranged between the first bristles 120 .

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

In the case of using a conventional toothbrush, bristles move as shown in FIG. 6(C) during brushing. That is, due to the inner bristles, the bristles are hardly inserted into the space between the teeth or sweep the teeth. As a result, the toothbrush cannot well remove foreign substances between the teeth. In particular, the toothbrush can hardly remove foreign substances stuck between teeth. Overall, existing toothbrushes can clean only a simple flat surface, and are therefore not suitable for brushing teeth with complex and severe concavo-convex curves.

In addition, in the conventional toothbrush, bristles cannot be inserted into the space 610 between teeth and gums, as shown in (D) and (E) of FIG. 6 . As a result, conventional toothbrushes cannot substantially clean between teeth and gums.

On the other hand, in the case of the toothbrush of the present invention, as shown in FIG. 6(A), the first bristles 120 are bent while brushing the teeth 600 during brushing.

Specifically, the first bristles 120-1, which were bent during brushing, hit foreign substances between the teeth with a large restoring force according to the movement of the toothbrush, or the first bristles 120-2 are inserted into the space between the teeth. Foreign matter between the teeth is removed by protruding outward of the teeth or pushed inward. That is, the toothbrush of the present invention is suitable for brushing teeth with complex and severe concavo-convex curves.

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 (B) of FIG. 6, In particular, it may be bent at 30 degrees or more (α), for example, 70 degrees or more. That is, at least one of the first bristles 120 is bent by more than 70 degrees during brushing, and as a result, the first bristles 120 hit foreign substances between teeth with the bending force (restoring force) as the toothbrush moves, or digs in between the teeth This structure is impossible in existing toothbrushes in which bristles have the same or almost 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 brushing operation of the first bristle 120 during brushing, and therefore, the first bristle 120 Foreign matter between the tooth 600 and the gum 602 610 can be easily removed by the s 120 . Specifically, as shown in (F) of FIG. 6, the first bristles 120 may be inserted between the teeth 600 and the gums 602 610 while being bent, and as a result, the teeth 600 and Foreign matter between the gums 602 610 may be removed. That is, one area (C) of the areas where brushing is concentrated by the first bristles 120 may be between the teeth 600 and the gums 602 610 as shown in FIG. . Therefore, it is possible to well remove the foreign matter between the tooth 600 and the gum 602 (610), and as a result, dental plaque can be prevented.

In particular, even if the first bristles 120 directly touch the gums, the first bristles 120 massage the gums while brushing, so that the gums can be strengthened by massaging without damaging the gums. On the other hand, in the conventional toothbrush, since the bristles touch the gums without being bent, it is easy to injure the gums.

In addition, since the length of the outermost first bristles 120 is long, it is possible to easily remove foreign matter near the gum 602 with a small space among the spaces between teeth.

In the case of brushing in the horizontal direction, the first bristles 120 penetrate between the teeth and the gums 602 and are excellent in removing foreign substances between the teeth and the gums 602, and both the horizontal brushing and the vertical brushing have long first brush heads. Because the field 120 digs between the teeth and strikes the foreign matter between the teeth, the effect of removing the foreign matter between the teeth is excellent.

On the other hand, dentists do not recommend brushing in the horizontal direction because conventional toothbrushes wear down the tooth surface when brushing in the horizontal direction. However, in the toothbrush of the present invention, since the short second bristles 122 do not touch the tooth surface, that is, only the long first bristles 120 touch the tooth surface, the tooth surface is hardly worn even when brushing in the horizontal direction. Therefore, brushing in the horizontal direction may also be possible.

According to one embodiment, since the second bristles 122 are significantly shorter than the first bristles 120, when the first bristles 120 are inserted between the teeth from the inside of the teeth as shown in (A) of FIG. The first bristles 120 may pass between the teeth. That is, the first bristles 120 perform a flossing function, and as a result, it is possible to easily and reliably remove interdental foreign matter without separately using dental floss or an interdental brush. In addition, it may have the same effect as that of scaling only by brushing teeth.

On the other hand, due to the short second bristles 122, it is possible to brush three sides of the teeth (teeth top, inner surface, and outer surface brushing) at once. This is impossible with conventional toothbrushes.

In addition, when the toothbrush is pushed in the direction of the molars 600a in a three-sided brushing state, the first bristle at the end of the first bristles 120, as shown in FIG. 7 (D) and FIG. 18 (C) It is possible to enter the back side (inside) of the molars 600a, so brushing the back side of the molars 600a may be possible. Therefore, brushing of wisdom teeth is also possible. Of course, the toothbrush of the present invention can brush teeth around the molars 600a as well as the back of the molars 600a. On the other hand, conventional toothbrushes are not only impossible to brush teeth on three sides, but also cannot brush the back of the molars because the bristles cannot enter the back of the molars even if the toothbrush is inserted in the direction of the molars.

In summary, the toothbrush of the present invention can perform horizontal brushing, vertical brushing, three-sided brushing, molar brushing, and flossing functions. That is, the toothbrush is an all-in-one toothbrush capable of performing various functions.

In general, tooth decay occurs because foreign substances are not properly removed. In the case of using a general toothbrush, since foreign substances remain on the teeth and the toothbrush itself acts as a source of contamination, the probability of tooth decay is high. Therefore, even if you brush your teeth a lot, caries easily occurs and you have to undergo expensive dental treatment, and as a result, dental treatment costs are inevitably high.

On the other hand, since the toothbrush of the present invention removes foreign substances almost completely, it is possible to innovatively improve the probability of tooth decay. In other words, even if you brush your teeth well, you can prevent tooth decay, so the number of dental treatments is reduced and the cost of dental treatment is significantly reduced.

Meanwhile, although not mentioned above, the toothbrush head and the toothbrush head may be separable. Therefore, the toothbrush can be used by replacing only the toothbrush head when necessary.

Looking at toothbrush cleaning, since the length of the second bristles 122 inside the first bristles 120 is short, even if foreign substances and toothpaste are placed on the second bristles 122 after brushing, foreign substances and toothpaste can be easily removed with water. can That is, even if you brush your teeth, you can hygienically manage your toothbrush.

On the other hand, in the conventional toothbrush, a lot of foreign substances and toothpaste remain between the bristles even after washing, and these foreign substances and toothpaste are not well removed. As a result, it is quite unsanitary and causes damage to the gums.

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

Referring to FIG. 8 , the toothbrush of this embodiment includes a toothbrush head (not shown), a support part 810 , first bristles 820 and second bristles 822 .

According to one embodiment, the toothbrush may be an electric toothbrush, and may have a structure in which the support part 810 and the toothbrush base are separable.

For example, a female screw is formed on the top of the toothbrush handle and a male screw is formed on a part of the support part 810 so that the toothbrush handle and the support part 810 can be separated. Of course, the support 810 may be rotated by a motor.

As another example, the support 810 may be rotatably coupled to the toothbrush holder manually even if the support part 810 is not powered. There are various techniques for this combination method, and any technique can be applied.

The bristles 820 and 822 may be arranged in a circular, oval or rectangular shape as shown in FIG. 8 . Here, the bristles 820 may correspond to the outermost bristles of a general electric toothbrush.

According to one embodiment, unlike a general electric toothbrush in which other bristles exist inside the outermost bristles, in the toothbrush of this embodiment, no bristles exist in the inner space (e) of the bristles 820 and 822. This is because the support part 810 rotates as shown in FIG. 8 during brushing, so that good brushing is possible even if there are no bristles inside.

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

In this case, when the support part 810 rotates, the first bristles 820 sweep the teeth. In particular, since the first bristles 820 are considerably bent and hit the foreign matter between the teeth with a bent force or are inserted between the teeth to push the foreign matter, the foreign matter between the teeth can be completely removed. 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 on the outermost part and the third bristles are arranged on the inside, the third bristles are the length of the first bristles 820 It may have a length of 70% or less of
