Interdental brush

The invention relates to an interdental brush for maintaining oral hygiene, which mainly improves the problem that the oral cleaning device is difficult to remove the back of the tooth, and can remove the food residue to effectively clean the teeth.

In recent years, with the progress of the times and the improvement of living standards, people pay more and more attention to the concept of oral hygiene habits. They will use toothbrushes and toothpastes to match each other immediately after eating to remove food residue left in the teeth and teeth to prevent dental caries. Oral lesions such as periodontal disease and inflammation of the gums. However, the location of the toothbrush and toothpaste is restrictive. It is not convenient to carry and can be used anytime and anywhere. It is also a good way to clean teeth by toothpicks. The toothpick is light and convenient to carry. The mouth is well hygienic.

Most of the earliest traditional toothpicks are made up of a slender rod. One end of the long rod is cut into a pointed shape. There is no special design on the structure. It only has the function of swarf and can not protrude into the gap to clean the gap. The tartar inside, and the tip is pointed and does not have the function of massaging the gums. There is also a dental floss stick that inserts the floss on the floss stick into the tooth gap, swings up and down and moves back and forth to clear In addition to the food residue in the tooth gap, the disadvantage is that if the force is applied improperly or the force is too much, the floss is broken, and the floss remains between the teeth, and the function of the floss for removing the adjacent teeth is weak.

A toothpick brush that has both the function of interdental brush and toothpick has been invented. It is an elongated rod having a gripping section and a picking section extending from one end of the gripping section, wherein the picking section has a loop. And a needle column extending outward from one side of the ring.

Devices having an interdental brush and a toothpick function have the following problems. In use, only the food residue can be hooked off, and the tartar between some teeth can be scraped off. It has no effect on the cleaning of the teeth behind the teeth, and can not enter between the relatively small teeth, such as between the incisors.

In order to solve the above problems, the present invention provides an interdental brush which can improve the difficulty of not removing the back of the tooth, and changes the material to a softer one, so that it penetrates into the size of the tooth gap to completely smash the food residue and scrape the tooth. Tartar includes between the teeth and behind the teeth.

In order to achieve the above object, the present invention provides an interdental brush comprising: a long rod, a half open long kit and a spring kit, the long rod having a grip portion and a tick extending from one end of the grip portion The tooth segment has a thin flat soft fork-like structure, and the gripping section is provided with a device for automatically rebounding the dent portion, so that the dent portion can be quickly moved back and forth in the semi-open long kit, which is thin and soft. When the fork-shaped structure protrudes from the pipe through the tooth gap, it can swing on the tongue surface of the tooth, thereby extending into the tooth gap to completely smash the food residue and scrape the tartar between the teeth and the teeth to achieve effective cleaning of the teeth.

Move the schematic when you use it.

The structure of the present invention will be described with reference to the drawings. Referring to FIG. 1 to FIG. 5-3, the present invention is an interdental brush for extending into a tooth T1 of a tooth T, and can remove tartar on the tooth T and clear the tooth gap T1. Residual food residue, or a gum T2 for massaging the tooth T, the structure comprising a long rod 100, a half open long kit 300, a spring kit 400, the long rod 100 having a grip portion 110 and a holding handle A picking section 120 extending at one end of the segment 110 has a thin flat soft fork-like structure, and the gripping section 110 is provided with a relative displacement of the picking section 120 relative to the semi-open long kit 300. The automatic rebound device is a spring kit 400.

Wherein, the picking section 120 of the long rod 100 has a thin flat rod-like structure, and the long rod 100 is formed by soft plastic injection molding, which is light and convenient to carry, so as to ensure good oral hygiene for a long time, the long rod 100 has a holding section 110 And a picking segment 120, wherein the picking segment 120 is a film-like structure having a fork-like structure 122 having a plurality of rough faces 121 at its front end.

Referring to FIG. 2 and FIG. 3 , the grip portion 110 is a rear half portion of the long rod 100 , and the grip portion 110 has a T-shaped rod shape 111 having a hardness to prevent the semi-open long kit 300 from being pulled. Slip-off, the grip section 110 has a tail-shaped tip 112 and a ball 113 at the end for the user to pick out larger swarf.

As shown in FIG. 2 to FIG. 4 , the dent portion 120 extends from one end of the grip portion 110 , and the front end of the dent portion 120 has a fork-like structure 122 , so that the dent portion 120 can extend into the The gingival T2 is not damaged in the tooth gap T1, and the front end of the dent portion 120 also has the effect of removing the food residue, and the tooth gap T1 is small, and some are larger, so the fork One end of the shaped structure 122 has different lengths, so that the picking section 120 can be applied to different sizes of the tooth gap. The front section of the picking section 120 can extend into the smaller tooth gap T1, as shown in FIG. 5-1. The entire section of the tooth section 120 can extend into the larger tooth gap T1, as shown in Figure 5-3, to achieve a wider range of applicable objects.

Since the tick section 120 is flat and slender, it is easy to cause distortion and it is difficult to enter the tooth gap T1. Therefore, the present invention encloses the long rod 100 in the semi-open type long kit 300, and the semi-open type long kit 300 front section 310 has a rectangular column shape, and the inside is The hollow structure can accommodate the picking section 120, as shown in FIG. 5-1 to FIG. 5-3, so that the picking section 120 can be telescopically displaced relative to the semi-open long kit 300. The semi-open long kit 300 The extended section 320 is extended in a semi-curved sheet shape to the rear end of the grip section 110, so that the long rod 100 can be moved back and forth.

1 , 2 and 3 , the spring kit 400 includes a wide hollow spring sleeve 410 , a thin hollow spring sleeve 420 and a spring 430 . The wide hollow spring sleeve 410 has a front opening 411 and a rear opening 412 . The thin hollow spring set 420 can be inserted into the thin hollow spring set 420, and the thin hollow spring set 420 can be passed out from the rear end opening 412 of the wide hollow spring set 410, while the thin hollow spring set 420 can cover the grip At the end of the holding section 110, a spring 430 is disposed inside the wide hollow spring sleeve 410, and the spring 430 covers the thin hollow spring sleeve 420 so that it can act as a reaction force when the semi-open long kit 300 moves over the long rod 110. The semi-open long kit 300 automatically bounces back and forth when moving forward and backward.

As shown in Figure 5-1~5-3, when the user holds the rear section of the long pole 100 and pulls down and pushes up from the semi-open long kit 300, the picking section 120 can be moved back and forth in the semi-open long kit. 300, at this time, the spring 430 is compressed by the extension section 320 to be compressed and rebounded, so that the picking section 120 can be moved back and forth quickly and maintain the thin flat fork-like structure 122 to achieve the effect of cleaning the teeth. The fork-like structure 122 of the dent portion 120 can also oscillate to the left and right of the tooth surface (back) after deepening the tooth gap, thereby cleaning the tartar behind the tooth.
