Description

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

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

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

In addition, since the inner bristles of the toothbrush interfere with the movement of the outer toothbrush bristles, the toothbrush cannot remove tartar that forms in the space between the teeth and gums, which increases the likelihood of developing gums.

As a result, dental floss etc. had to be used separately, and it was difficult to prevent cavities even if teeth were brushed, and therefore expensive dental treatment had to be frequently received due to cavities.

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

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

Existing toothbrushes that advertise that dental floss is not necessary remove foreign substances between teeth to a certain extent, but foreign substances often remain between teeth even after brushing. In particular, foreign substances inserted between teeth are almost impossible to remove, so there is no choice but to use dental floss. .

Additionally, because the toothbrush bristles have the same length, when removing tartar between teeth and gums, the toothbrush bristles cannot properly remove foreign substances between teeth and gums due to neighboring toothbrush bristles. As a result, tartar builds up between the teeth and gums, causing tooth decay, and as a result, the gums become weakened.

In addition, even if the toothbrush was washed with water after brushing the teeth, foreign substances and toothpaste that penetrated between the toothbrush bristles were hardly removed. As a result, the toothbrush itself is prone to contamination, so continuous use of the toothbrush can have a negative effect on 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 substances between teeth can be completely removed, and this was confirmed through actual experiments. In particular, the toothbrush can remove foreign substances strongly stuck between teeth. As a result, there is no need for dental floss.

Additionally, because the length of the second bristles is significantly shorter than the length of the first bristles, the second bristles are not in the way when the first bristles remove tartar between the teeth and gums. As a result, tartar between the teeth and the gums can be well removed using the first toothbrush bristles, and as a result, tartar does not exist between the teeth and the gums, and dental plaque can be prevented. Additionally, since the first toothbrush bristles are swept, the gums may not be damaged even if the teeth are brushed across the gums.

In addition, when you wash the toothbrush itself after brushing your teeth, the length of some toothbrush bristles is quite short, so foreign substances and toothpaste that have penetrated between the bristles are almost completely removed, and contamination of the toothbrush itself can also be prevented.

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

Figure 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, and Figure 3 is a toothbrush according to an embodiment of the present invention. It is a floor plan. Figure 4 is a diagram showing the comparative structure of the first and second toothbrush bristles according to an embodiment of the present invention, Figure 5 is a diagram showing the shape of the first toothbrush bristles according to an embodiment of the present invention, Figure 6 and 7 are diagrams showing the foreign matter removal process using a conventional toothbrush and a toothbrush of the present invention.

1 to 3, the toothbrush of this embodiment includes a toothbrush stand 100 and a toothbrush head 102. The shape of the toothbrush stand 100 is not limited to the structure shown in FIG. 1 and can be modified in various ways, and an existing toothbrush stand can also be adopted.

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

The first toothbrush bristles 120 are relatively long toothbrush bristles and may be installed on the support unit 110 . For example, the first toothbrush bristles 120 may be inserted into and fixed in the holes of the support part 110.

The first bristles 120a and 120d are the outermost bristles in the longitudinal direction of the toothbrush head 102, and the first bristles 120b and 120c are the bristles other than the outermost first bristles 120a and 120d. 1 These are toothbrush bristles. The first toothbrush bristles 120a, 120b, 120c, and 120d may have the same or similar length as the bristles of a regular toothbrush.

According to one embodiment, the outermost first toothbrush bristles 120a and 120d may have a long length, and the next toothbrush bristles 120b and 120c may have a short length. However, in this case, there is only one first toothbrush bristle (120a and 120d), so it is difficult to maintain force. Therefore, it is efficient for the outermost first toothbrush bristles 120a and 120d and the subsequent toothbrush bristles 120b and 120c to have a long length, so that teeth can be brushed with sufficient force. However, if the number of the outermost first toothbrush bristles 120a and 120d is three or more, the subsequent bristles may have a short length. Of course, considering brushing the innermost teeth, it is preferable that there are two or less outermost first toothbrush bristles 120a and 120d on one side.

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

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

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

If the length (h2) of the second toothbrush bristles (122) exceeds 70% of the length (h1) of the first toothbrush bristles (120), it is possible to sufficiently remove foreign substances between the teeth even if the first bristles (120) are swept during brushing. It was difficult. This is because the first toothbrush bristles 120 cannot strike foreign substances between the teeth with sufficient force and the first toothbrush bristles 120 cannot be properly inserted into the space between the teeth.

Of course, when the length (h2) of the second toothbrush bristles 122 is about 70% to 50% of the length (h1) of the first toothbrush bristles 120, the length (h2) of the second toothbrush bristles 122 is longer than the first toothbrush bristles (122). The effect of sweeping or digging between teeth or between teeth and gums may be reduced compared to when it is less than about 50% of the length (h1) of the second toothbrush bristles (120), but the length (h2) of the second toothbrush bristles (122) is greater than that of the first toothbrush bristles (120). ) is more effective than when it exceeds 70% of the length (h1) and can sufficiently remove foreign substances.

If the length h2 of the second toothbrush bristles 122 exceeds 70% of the length h1 of the first toothbrush bristles 120, the effect of sweeping or digging between teeth or between teeth and gums is substantially insignificant. In other words, a toothbrush whose bristles are all the same length or have slightly different lengths does not operate to substantially sweep. As a result, it is impossible to sufficiently remove foreign substances between teeth, and in particular, it is almost impossible to remove foreign substances between teeth that are strongly stuck.

On the other hand, if the length (h2) of the second toothbrush bristles 122 is 70% or less, preferably 50% or less, of the length (h1) of the first toothbrush bristles 120, the first toothbrush bristles 120 can be sufficiently used when brushing teeth. As you brush your teeth, you can almost completely remove foreign substances between your teeth. Specifically, when brushing teeth, the second toothbrush bristles 122 are supported by the tooth surface, and the long first toothbrush bristles 120 sweep the teeth while the second toothbrush bristles 122 are supported by the teeth. do. As a result, the curved first toothbrush bristles 120 hit the foreign matter between the teeth with sufficient force, so that the foreign matter between the teeth can be sufficiently removed. The operation of this toothbrush will be described in detail after looking further at the structure of the toothbrush.

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

In addition, in order to maximize the writing effect, the first toothbrush bristles 120 include first brushes 300 with triangular ends as shown in FIG. 5 and second brushes with a length shorter than that of the first brush 300. It may be a double coat consisting of (302).

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

In summary, setting the length of the second toothbrush bristles 122 to 70% or less of the length of the first toothbrush bristles 120, preferably 50% or less, is effective in removing foreign substances between teeth and tartar between teeth and gums. am.

From another perspective, the bristles adjacent to the long bristles may have a short length for a brushing effect. For example, with respect to a long toothbrush bristle, at least one of the neighboring toothbrush bristles in the north, south, east, west, and west directions 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 can be modified in various ways.

From another perspective, short bristles may not be arranged but empty spaces may be arranged between the long bristles. In other words, empty space can replace the short toothbrush bristles. As a result, the effectiveness of writing can be maximized.

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

Hereinafter, we will look at the operation of the toothbrush when brushing teeth with reference to FIGS. 6 and 7.

When using a conventional toothbrush, the toothbrush bristles move as shown in (C) of FIG. 6 when brushing teeth. That is, due to the inner bristles, the bristles rarely sweep the teeth or are inserted into the space between the teeth. As a result, the toothbrush cannot well remove foreign substances between teeth. In particular, the toothbrush can hardly remove foreign substances stuck between teeth. Overall, existing toothbrushes can only clean simple flat surfaces, making them unsuitable for brushing teeth that have complex, uneven, and curved teeth.

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

On the other hand, in the case of the toothbrush of the present invention, as shown in Figure 6 (A), the short second toothbrush bristles 122 are supported by the teeth 600, and the first toothbrush bristles 120 ) is bent and sweeps the teeth 600.

Specifically, the first toothbrush bristles 120-1, which are bent during brushing, hit foreign substances between the teeth as the toothbrush moves, or the first toothbrush bristles 120-2 are inserted into the space between the teeth. As a result, foreign substances between the teeth are discharged to the outside or inside of the teeth 600 and removed. In other words, the toothbrush of the present invention is suitable for brushing teeth 600 that are complex and have severe irregularities and curves.

According to one embodiment, since the length of the second bristles 122 is less than 70% of the length of the first bristles 120, the first bristles 120 are bent as shown in (B) of FIG. 6. , In particular, it can be bent more than 30 degrees (α), for example, 70 degrees. That is, at least one of the first toothbrush bristles 120 is bent more than 30 degrees when brushing teeth, and as a result, the first toothbrush bristles 120 hit foreign substances between the teeth or remove debris between the teeth with the bending force as the toothbrush moves. It is inserted into space. This is a structure that is impossible with existing toothbrushes where the bristles have the same or nearly similar length.

Meanwhile, since the length of the first toothbrush bristles 120 is considerably longer than the second bristles 122, the second bristles 122 do not interfere with the brushing action of the first bristles 120 when brushing teeth, and therefore the first bristles 120 The tartar between the teeth 600 and the gums 602 (610) can be easily removed by the teeth (120). Specifically, as shown in (F) of FIG. 6, the first toothbrush bristles 120 may be bent and inserted between the teeth 600 and the gums 602 (610), and as a result, the teeth (600) and Tartar between the gums 602 (610) can be removed. That is, one area (C) of the areas where teeth brushing is concentrated by the first toothbrush bristles 120 may be between the teeth 600 and the gums 602 (610) as shown in (A) of FIG. . Therefore, tartar between the teeth 600 and the gums 602 (610) can be well removed, and as a result, dental plaque can be prevented.

In particular, even if the first toothbrush bristles 120 directly contact the gum area C, the first toothbrush bristles 120 are bent during brushing and do not cause damage to the gums. As a result, blood may not come out even if you brush your teeth. On the other hand, in conventional toothbrushes, the bristles touch the gums without being bent, so it is easy to injure the gums, and as a result, blood often comes out when brushing the teeth.

In addition, because the length of the first toothbrush bristles 120 is long, foreign substances near the gum 602, which has a small space between teeth, can be easily removed. Specifically, when brushing teeth, the first toothbrush bristles 120 are likely to move near the gums 602 and the first toothbrush bristles 120 hit foreign substances between the teeth with strong force or are inserted between the teeth, so the gums 602 ) Nearby foreign substances can be easily removed. In other words, the efficiency of removing foreign substances near the gums 602 is excellent.

When divided into horizontal brushing and vertical brushing, in the case of horizontal brushing, the first toothbrush bristles 120 are more likely to bend and hit foreign substances or dig into the space between the teeth and gums 602, thus causing more damage to the teeth and gums. While it is excellent for removing foreign substances in the space between the gums 602 or foreign substances in the space between the teeth near the gums 602, in the case of vertical tooth brushing, the first toothbrush bristles 120 are inserted into the space between the teeth. Since it occurs more frequently, it is excellent for removing foreign substances from tooth spaces other than those near the gums 602. Therefore, by brushing your teeth in the horizontal direction and brushing your teeth in the vertical direction, foreign substances can be removed throughout the space between teeth, including near the gums. As a result, there is no need for flossing at all.

Meanwhile, with the existing toothbrush, the bristles could not be inserted into the teeth 600 in a direction parallel to the teeth, but in the toothbrush of the present invention, the length of the second bristles 122 is short, so the first bristles 120 As shown in (B) of FIG. 7, it can be inserted into the tooth 600 from the top of the tooth in a direction parallel to the tooth 600. That is, the first toothbrush bristles 120 surround the teeth. Of course, when the first toothbrush bristles 120 enter to a certain extent, the entry of the second toothbrush bristles 122 is blocked by the top of the tooth, so the first toothbrush bristles 120 no longer enter. In this way, after inserting the first toothbrush bristles 120 into the teeth 600 from the top of the teeth 600, teeth brushing can be performed in a direction perpendicular to the teeth 600. As a result, the outer and inner surfaces of the teeth 600 can be brushed at once. Of course, this brushing effect can be applied not only to the lower teeth but also to the upper teeth. This method of brushing teeth cannot be used with a conventional toothbrush.

Additionally, the toothbrush of the present invention can brush the innermost teeth (600a, for example, molars) among the teeth (600). In the case of a conventional toothbrush, as shown in (C) of FIG. 7, the toothbrush bristles have the same length, so the innermost teeth (600a, for example, molars) cannot be brushed. On the other hand, since the first toothbrush bristles 120 of the toothbrush of the present invention are significantly longer than the second bristles 122, as shown in (D) of FIG. 7, the first bristles 120 are aligned with the innermost teeth ( 600a) You can brush your teeth.

In summary, the toothbrush of the present invention performs all of horizontal brushing, vertical brushing, and brushing of the outer and inner surfaces of the teeth 600 at once with the first toothbrush bristles 120 inserted into the teeth 600. You can do this, and through these three brushing methods, you can completely remove foreign substances between your teeth. In particular, the efficiency of removing tartar between the teeth 600 and the gums 602 is excellent, and the inner surface of the innermost tooth 600a can also be brushed.

Generally, cavities occur because foreign substances are not properly removed, but when using a regular toothbrush, foreign substances remain on the teeth and the toothbrush itself acts as a source of contamination, so the probability of cavities occurring is high. Therefore, even if you brush your teeth a lot, cavities easily occur and you have to undergo expensive dental treatment, and as a result, the cost of dental treatment is inevitably high.

On the other hand, since foreign substances are almost completely removed when the toothbrush of the present invention is used, the probability of developing cavities can be drastically improved. In other words, you can prevent cavities just by brushing your teeth well, which reduces the number of dental treatments and significantly reduces the cost of dental treatment.

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

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

On the other hand, even if a conventional toothbrush is washed, a lot of foreign substances and toothpaste remain between the bristles, and these foreign substances and toothpaste are not easily removed. As a result, it is quite unhygienic and causes damage to the gums.

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

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

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

For example, a female thread may be formed on the top of the toothbrush stand, and a male thread may be formed on a portion of the support portion 810, so that the toothbrush stand and the support portion 810 may have a separable structure. Of course, the support portion 810 can be rotated by a motor.

As another example, even if the support part 810 is not electric, it can be rotatably coupled to the toothbrush stand manually. There are various technologies for this combination method, and any technology can be applied.

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

According to one embodiment, unlike a regular electric toothbrush in which other bristles exist 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 support portion 810 rotates as shown in FIG. 8 when brushing teeth, so good teeth brushing is possible even if there are no toothbrush 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 portion 810 rotates, the first toothbrush bristles 820 brush the teeth. In particular, since the first toothbrush bristles 820 are significantly bent and strike foreign substances between teeth with a bending force or are inserted between teeth to push out foreign substances, foreign substances between teeth can be completely removed. In this case, the second toothbrush bristles 122 may not interfere with the writing operation of the first toothbrush bristles 820.

According to another embodiment, the first bristles 820 and the second bristles 822 are arranged on the outermost side and third bristles are arranged on the inside, wherein the third bristles are the length of the first bristles 820. It can have a length of less than 70% of .
