Description

Exceptional toothbrush for removing foreign substances in teeth}

The present invention relates to a toothbrush consisting of a handle, a head, and a bristle, and more specifically, the support between the brush heads in contact is strengthened according to a structure in which the bristles are inclined toward the top, so that plaque and foreign matter generated on the surface of the teeth when brushing teeth The present invention relates to a toothbrush that is excellent in removing foreign substances from teeth that can be easily and effectively removed, and that a single toothbrush can be used for a long time by minimizing the phenomenon that the bristles spread outward.

In general, a toothbrush is a tool for oral hygiene that is used together with toothpaste, and is largely divided into a handle portion for gripping by hand and a head portion provided with bristles that directly rub against the teeth. The handle part is standardized to be bent at an ergonomic angle to facilitate the most common rotation method among the methods of brushing teeth, but the head part that has a cleaning function by directly rubbing against the teeth, i.e., in the case of the bristles, not only the tooth structure but also the gums It has various structures in consideration of health conditions.

In addition, in order to remove impurities such as food debris or tartar stuck between the teeth using a general toothbrush, brush the teeth as if scraping between the teeth by using the edge of the brush head with the head of the toothbrush tilted. Only the edge of the toothbrush is opened as if falling in both directions, acting as a major factor in shortening the life of the toothbrush.

As an example, according to Korean Patent Publication No. 0656887, "In constituting a toothbrush with a handle extending from the head portion where the bristles are planted: the head portion 1 is bisected, and the fixed head 10 and the variable head 20 However, the fixing head 10 is formed integrally with the handle part 2 of the toothbrush B, and the receiving groove 12 is provided on the side surface, and the support grooves at both ends of the receiving groove 12 ( 12a) and a support rod (12b) are formed, and the variable head 20 is manufactured separately from the handle portion 2 of the toothbrush (B), and inserted into the receiving groove 12 of the fixed head 10 Fastening rods (20a) and fastening holes (20b) are provided at both ends corresponding to the support grooves (12a) and the support rods (12b), and a stop bar (32) close to the fastening holes (20b) of the variable head (20) A toothbrush capable of adjusting the width of the bristles, characterized in that it comprises a protruding, fixing means (30) having a fastening groove (34) on the fixing head (10) corresponding to the stop rod (32). Present ".

These prior literatures show that the head of the toothbrush is divided into two, and the head is variable at one end so that the width of the bristles is adjusted to suit the user's tooth structure, thereby maximizing the effect of brushing teeth. It states that it provides toothbrushes where possible.

However, in the prior literature, the head part 1 of the toothbrush is divided into two parts and manufactured into a fixed head 10 and a variable head 20, so that the necessary elements up to the fixing means 30 for fixing these components to each other should be additionally configured. In the case of a toothbrush that is brushed for a certain period of time and replaced with a new toothbrush, the cost of manufacturing will increase, and the efficiency of the work to be fixed will decrease as the configuration is added. It would be virtually difficult to determine whether the effect of brushing can be maximized.

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

The present invention relates to a toothbrush consisting of a handle 10, a head 20, and a bristle 30, and the bristle 30 is the main configuration.

The toothbrush of the present invention is based on the fact that the head 20 is integrally coupled to the upper part of the handle 10 and the circumference becomes thicker toward the lower part to increase the grip feeling that is gripped by hand. It is also possible to use a toothbrush with a handle 10 and a head 20 that has been made. The basic configuration of the toothbrush is regarded as important, but the handle 10 and the head 20 correspond to indirect configurations in brushing teeth, so the following is omitted, and the present invention focuses on the bristles 30 for brushing teeth directly in contact with the teeth. To explain.

In addition, the bristles 30 according to the present invention are provided with 1 row hair 31 and 2 row hair 32 in the center of the head 20, and 3 row hairs 33 and 4 row hairs 34 at both edges, respectively. It is provided with a number of at regular intervals. The bristle heads 30 are basically arranged at regular intervals on the head 20 of the toothbrush by using as a unit grouped in a certain quantity, and the first row of bristle 31 and the second row of bristle from the center of the surface of the head 20 A number of 32 are provided at regular intervals. The first row of hairs 31 and the second row of hairs 32 are provided with bristle heads 30 of a unit at regular intervals in a linear direction from the upper end of the head 20 to the lower end. The bristle heads 30 of the same unit as above are placed at regular intervals on both edges of the head 20 provided with the first row hair 31 and the second row hair 32 and the third row hair 33 and the fourth row hair 34 There are many.

And the first row of hairs 31 and the second row of hairs 32 are provided in a linear direction to the top and bottom of the head 20, instead of the three-row hairs 33 and the four-row hairs 34 of the head 20 This is a bar indicating that the positions provided may vary slightly depending on the shape of the head 20 because it is provided vertically along the edge. In the drawing shown, the bristles 30 are expressed as one unit for each unit, which is difficult to express one by one on the drawing because the thickness of the bristles 30 is thin, so that a unit that bundles a certain quantity is abbreviated to one bristle 30. However, in reality, fine hairs of a thin thickness are densely provided in the receiving hole of the head 20 to constitute one unit, and at least one or more units are provided at regular intervals.

At this time, according to the detailed configuration of the present invention, the bristle 30 has an upper end (α') in contact with the teeth at the lower end (α) of the 3 row hairs 33 and the 4 row hairs 34 planted in the head 20 is 15 ~ It is characterized in that it is provided to be inclined inward from about 60 degrees. With the feature of the bristles 30 having a plurality of bristles on the head 20, it is brushed by direct contact with the teeth based on the lower end (α) of the 3 row hairs 33 and the 4 row hairs 34 planted in the head 20. The upper part (α') is characterized in that it is provided to be inclined in an inward direction provided by the first row hair 31 and the second row hair 32 between an angle of about 15 to 60 degrees. Since the 3 row hairs 33 and the 4 row hairs 34 of the bristles 30 are provided in opposite directions, the 3 row hairs 33 and the 4 row hairs 34 are respectively planted on the head 20 at the lower end (α) Beginning with, the upper end (α'), which is a part that directly removes plaque and foreign matter by contacting the teeth, is provided to be inclined inward at a constant angle of 15 to 60 degrees, and interlocked with the first row hair 31 and the second row hair 32 While increasing the support, the effectiveness of brushing your teeth is proportional, increasing the efficiency. And since the upper end (α') of the bristles 30 narrows to the top and inclines to contact, the general toothbrush minimizes the spread of the 3 row hairs 33 and the 4 row hairs 34 located at the edges while brushing teeth repeatedly. It also has the advantage of increasing the contrast replacement cycle.

In addition, according to the detailed configuration of the present invention, the bristles 30 have a width of the lower end (β) of the 3 row hairs 33 and the 4 row hairs 34 planted in the head 20 within 10 to 15 mm, and contact the teeth. It is characterized in that the upper end portion (β') has a width of about 3 to 6 mm, and has a width (γ) of about 3 to 8 mm on the surface of the head 20. In addition to the method of providing the above-described 3-row hairs 33 and 4-row hairs 34 to be inclined at an angle within 15 to 60 degrees, the opposite of the 3-row hairs 33 and 4-row hairs 34 planted on the head 20 The width of the lower end (β) is 10 ~ 15mm, and the width of the opposite upper end (β') of the 3rd row hairs 33 and 4th row hairs 34 that directly contact the teeth to remove plaque and foreign matter is about 3 ~ 6mm The brush heads 30 are formed to be densely formed in the center where the first row 31 and the second row 32 are located as the entire bristles 30 go to the top, so that the bristles 30 increase mutual support, so that plaque or foreign matter is easily removed. It can, of course, have the advantage of increasing the replacement cycle of the toothbrush by minimizing the outward opening of the three-row hairs 33 and the four-row hairs 34 of the edges.

And it is characterized in that it has a gap width (γ) of about 3 ~ 8mm in an arbitrary position among the total length width in the vertical direction based on the surface of the head 20 having the bristles 30, the bristles ( 30) The teeth are accommodated in the gap (γ) provided between the teeth, and the bristles 30 located above and below the gap (γ) brush not only the surface of the tooth, but also the gap between the tooth and the tooth to effectively remove foreign substances such as tartar. Can be removed.

As described above, in the present invention, the support force between the bristles that are in contact is strengthened according to the structure in which the bristles are inclined toward the top, so that plaque and foreign matter generated on the surface of the teeth when brushing can be easily and effectively removed, and the bristles open outward. By minimizing the phenomenon, it provides the effect of using one toothbrush for a long time.
