Description

  The present invention relates to massage of gums and a soft interdental brush capable of removing food or plaque remaining in the interdental space.

In order to care in the oral cavity and maintain the health of the teeth, a toothbrush, toothpick or dental floss is usually used.
However, the shape of the toothbrush is fixed, it is difficult to make it correspond completely to the shape of the tooth, and it can not enter into the interdental space, and it is easy to completely eliminate the food remaining in the interdental space. Absent.
Therefore, care is generally provided using toothpaste or dental floss as a supplement.
Toothpaste can remove food debris, but because it is hard, it causes gum bleeding or tooth surface defects.
Dental floss, on the other hand, can enter between the teeth but can only remove some of the food debris and can not be cared for thoroughly.
Thus, interdental brushes have been developed to thoroughly care for the teeth and to keep the oral cavity hygienic.

As shown in FIG. 1, the conventional interproximal brush 1 has a holder 11, a rod 12 extending out of the holder 11, and a plurality of flexible brushes 13 radially extending outward from the rod 12.
However, although the interdental brush 1 can penetrate into the teeth and perform care of the teeth and massage the gums, the surface area where the soft brush 13 entering the interdental contacts the gum site and the interdental surface is extremely small. The effect of the massage on the gums of interdental brush 1 is not sufficient.
Furthermore, in the process of applying an external force, the soft brush 13 can not draw out plaque or food debris out of the interdental space with sufficient strength, so the cleaning effect is low and improvement is necessary.

As described above, in the conventional interdental brush, the brushing effect on the gums of the interdental brush is not sufficient because the surface area where the brush and the gum site and the interdental surface coming into the interdental contact are extremely small. There is a disadvantage that the cleaning effect is low because the brush can not pull out plaque or food debris out of the interdental space with sufficient strength.
The problem to be solved by the present invention is to provide an interdental brush capable of reliably removing gums and food or plaque remaining in the space between teeth, and effectively enhancing the cleaning effect and convenience. .

  The interdental brush of the present invention includes a holder, a rod extending from the holder, and a cleaning set installed on the rod, and the cleaning set is installed in a plurality of rings on the outer peripheral surface of the rod. The cleaning unit has a contact surface facing in the direction of the holder, and a peripheral wall extending from the contact surface in the direction opposite to the holder while the diameter is gradually reduced, and the contact The diameter of the surface is larger than the diameter of the rod portion, and a pointed portion is formed at the connection position of the contact surface and the peripheral wall.

The cleaning units may be spaced apart from one another.
Alternatively, the peripheral wall of each cleaning portion may extend and be connected to the contact surface of another cleaning portion adjacent thereto, whereby the cleaning portions may be connected in series on the rod portion.
In this case, long and short peripheral walls of each cleaning unit may be alternately installed.
Alternatively, at least two of the cleaning units are connected to each other to form a unit, and the units are spaced apart from each other and installed on the rod unit.
The contact surface may be recessed to form a storage space on the holder side of the contact surface.

In the interdental brush of the present invention, since the peripheral wall is gradually contracted and the cleaning portion has a cone shape, the rod portion and the cleaning portion easily enter between the teeth and moreover, when the interdental brush is pulled out, The support of the peripheral wall and the sharp edge can obtain better support power, scraping away the food or plaque remaining between the teeth and bringing it out between the teeth.
Therefore, the cleaning effect between the teeth can be greatly improved, and at the same time, the cleaning part is installed annularly surrounding the rod part, so the contact area between the cleaning set and the gums and teeth is large, and food debris or plaque can be effective. As well as being able to be removed, the effect of gum massage can be achieved in the cleaning process and can be used more conveniently.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
As shown in FIGS. 2 and 3, the interdental brush 3 of the first embodiment includes a holder 31, a rod 32 extending from the holder 31 to form an end 321, and a cleaning set 33 installed on the rod 32. Have.

The cleaning set 33 has a plurality of cleaning units 330.
Each cleaning unit 330 is annularly installed on the outer periphery of the rod 32. That is, each cleaning portion 330 is formed to surround the outer periphery of the rod portion 32.
Each cleaning portion 330 has a contact surface 331 and a peripheral wall 332 extending following the contact surface 331.
The contact surface 331 is a surface orthogonal to the central axis of the rod 32, and faces the direction of the holder 31, and the diameter of the contact surface 331 is larger than the diameter of the rod 32.
The peripheral wall 332 extends from the outer peripheral edge of the contact surface 331 in the direction opposite to the holder 31 while gradually reducing the diameter. That is, the circumferential wall 332 gradually contracts toward the end 321 of the rod portion 32.

Further, a pointed portion 333 is formed at the connection position of the contact surface 331 and the peripheral wall 332.
The acute angle portion 333 is formed on the outermost periphery of the contact surface 331, whereby the entire cleaning portion 330 has a conical shape (such as a conical shape) and is annularly disposed on the rod portion 32.
Therefore, the cleaning unit 330 can enter the space between the teeth from the small diameter side to remove foreign matter, and achieve the gum massage effect.
Furthermore, the cleaning units 330 are spaced apart from each other, and the bar units 32 are exposed between the cleaning units 330 (see FIG. 2).

Alternatively, as in the second embodiment illustrated in FIG. 4, the cleaning units 330 may be connected in series with one another. That is, the peripheral wall 332 of the cleaning unit 330 extends and is connected to the contact surface 331 of another cleaning unit 330 adjacent to the cleaning unit 330.
The cleaning unit 330 is manufactured using a soft material such as a material having flexibility or elasticity, and avoids injury to teeth and gums.

As shown in FIG. 5, in use, the user holds the holder 31 in hand and inserts the rod portion 32 between the teeth of any two teeth A.
The peripheral wall 332 gradually shrinks toward the end 321 of the rod portion 32 to form a cone shape, so that the cleaning portion 330 quickly and easily enters between the teeth.
In addition, since the cleaning unit 330 is designed to be installed annularly around the entire rod 32, it can contact the gums in a sufficient area to achieve the gum massage effect.

When the user pulls the cleaning set 33 out of the interdental space, the sharp edge portion 333 and the contact surface 331 of each cleaning portion 330 receive a support function of the peripheral wall 332, so they have sufficient support power and the cleaning operation It can be performed.
That is, the sharp corner portion 333 can effectively scrape off the dental plaque on the surface of the tooth A and the food residue remaining between the teeth, and the plaque and debris after scraping are placed on the contact surface 331, and the withdrawal operation is performed. Accordingly, it is pulled out together with the contact surface 331, thus effectively enhancing the cleaning effect of the teeth and the convenience of use.

As shown in FIG. 6, the interdental brush 3 of the third embodiment has a holder 31, a rod portion 32 extending from the holder 31, and a cleaning set 33 installed on the rod portion 32.
The components of the holder 31, the rod portion 32, and the details of the cleaning set 33 and the purpose and effects thereof are the same as those of the first embodiment, and therefore will not be described in detail here.
In the cleaning set 33, at least two cleaning units 330 mutually connect to form a unit.
The units are spaced apart from one another and installed on the rod 32.
In the example shown in the drawing, each cleaning unit 330 is connected two by two to form one unit, but more than two cleaning units 330 may be connected.

As shown in FIG. 7, the interdental brush 3 according to the fourth embodiment has a holder 31, a rod 32 extending from the holder 31, and a cleaning set 33 installed on the rod 32.
Similar to the second embodiment described above, the plurality of cleaning units 330 of the cleaning set 33 of the present embodiment also exhibit a serial connection method.
The difference between the two is that in the present embodiment, the extended length of the peripheral wall 332 of each cleaning portion 330 is alternately set to a long one and a short one.

  Whether each cleaning unit 330 is spaced apart or installed in series, whether it is alternately installed with long or short peripheral walls 332, all have a tooth cleaning and massage effect on the gums, The oral cavity is kept hygienic and the best condition can be achieved.

As shown in FIG. 8, the interdental brush 3 according to the fifth embodiment has a holder 31, a rod 32 and a cleaning set 33.
In the present embodiment, the contact surface 331 of each cleaning portion 330 is gradually recessed from the outer peripheral edge toward the rod portion 32 so as to form an accommodation space 334.
That is, since the accommodation space 334 is formed on the holder side of the contact surface 331 in a depression between the rod 32 and the sharp edge 333, the accommodation space 334 is inserted after the cleaning unit 330 is inserted between the teeth. It can contain plaque and food debris.
As a result, dental plaque and food debris can be more easily taken out of the interdental space, and the interdental cleaning effect can be enhanced.

In summary, the interdental brush of the present invention has the cleaning portions annularly disposed on the bar portion, and the cleaning portion has a contact surface whose diameter is larger than the rod portion diameter, and gradually from the contact surface toward the end of the rod portion. The entire cleaning portion has a conical shape because it has a peripheral wall inclined so as to have a smaller diameter, and a sharp corner portion located at the connection point between the contact surface and the peripheral wall.
Therefore, in use, the peripheral wall, which has a gradually shrinking shape, easily enters into the space between the teeth, and when pulling out the interdental brush, the support action of the peripheral wall is used, and the apex and the contact surface are sufficient. The food or plaque remaining between the teeth can be scraped and removed to provide a good support.
In addition, the interdental brush contacts the gums in a sufficient area and achieves the effect of gum massage, since the cleaning part is installed in a pyramid shape and in an annular shape.
Thus, the dual effects of tooth cleaning and gum massage can be achieved to enhance the convenience of use.

  The above is a description of an embodiment, and does not limit the present invention, and therefore, the scope of the present invention is based on the claims described later.
