Description

interdental brush

technical field

The invention relates to an appliance for maintaining oral hygiene, in particular to an interdental brush for cleaning teeth.

Background technique

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. After eating, they will immediately use toothbrush and toothpaste to remove food residues remaining in the teeth and interdental gaps, so as to prevent Dental caries, periodontal disease, gingival inflammation and other oral diseases. But the place and timing of using toothbrush and toothpaste have its limitation, can't carry conveniently and use anytime and anywhere, then the mode of picking one's teeth with toothpick is also a kind of good method of cleaning teeth. Toothpicks are lightweight and easy to carry, regular use of toothpicks can keep good oral hygiene forever.

Most of the earliest traditional toothpicks are made of a slender rod. One end of the long rod is cut into a pointed shape. There is no special design in the structure. The tartar in the crevice, and because the end is pointed, it does not have the function of massaging the gums.

There is another kind of dental floss stick, which inserts the floss on the dental floss stick into the gap between the teeth, swings up and down and moves back and forth to remove food residues in the gap between the teeth. The disadvantage is that if the force is applied improperly or excessively, it will easily cause If the dental floss breaks, the dental floss remains between the teeth, and the function of the dental floss to clean the adjacent teeth is relatively weak.

The existing toothpick brush that has interdental brush and toothpick function concurrently has been invented at present, and it is a slender rod, has a holding segment and a teeth-picking segment extending from one end of the holding segment. Wherein the tooth-picking segment has a ring and a plurality of needle columns extending horizontally outward from one side of the ring, which can be inserted into the gap between the teeth to scrape off food residues inside.

So far, the devices that have the functions of interdental brushes and toothpicks have the following problems: Although they can pick out food residues and scrape off the tartar between some teeth during use, the end of the needle column designed in a horizontal manner is entering the gap between the teeth. During the process of shaving food residues, it is easy to scratch the gums in the interdental space, causing users to bleed. In addition, it does not have the effect of cleaning the tartar at the back of the teeth, and the design restriction cannot enter the relatively small gaps between the teeth, such as between the front teeth.

Contents of the invention

The interdental brush includes a long rod 100 and a set 200 .

The long rod 100 has a holding section 110 and a teeth picking section 120 extending from one end of the holding section 110 . As shown in Figure 3 and Figure 3-1, the front end of the teeth picking section 120 is a fork structure part 121, the fork structure part 121 is made of soft material, and its shape is a flat fork shape , the fork structure part 121 has 3 forks (in other embodiments, 2 forks, 4 forks, or 5 forks, etc. can also be set), and each fork is provided with A plurality of coarse particles 122 (for example, 3 to 20). One side of the gripping section 110 extends outwards to be provided with a positioning portion 111, and one end of the gripping section 110, which is located away from the teeth picking section 120, is provided with a tapered tip 112, and on the tip 112 is extended with a ball 113 . In this embodiment, the long rod 100 is a one-piece injection-molded piece made of polypropylene (PP) plastic particles, and its Rockwell hardness is 85, which is not only light and portable, but also makes the long rod 100 Each fork piece of the fork structure part 121 of the tooth picking section 120 can be bent to the rear of the corresponding tooth T by a certain curvature after being inserted into the tooth gap T1 to be cleaned, which is beneficial to cleaning the rear part of the tooth T. To maintain good oral hygiene forever.

The kit 200 is also an integral part of injection molding, and the selected material is ABS plastic or polypropylene. The set 200 has a set portion 210 and a rail portion 220 . When in use, the long rod 100 can move its holding section 110 on the rail part 220 , and can make its teeth picking section 120 move in and out of the sleeve part 210 in a movable manner. In this embodiment, as shown in Figure 4 and Figure 4-1, the sleeve part 210 is a fan-shaped cylindrical hollow structure, which can be used for the tooth-picking section 120 of the long rod 100 to pass through, so that the long rod 100 is relatively opposite to the sleeve. 200 for skidding. One end of the positioning portion 111 of the long rod 100 can abut against the rail portion 220 of the kit 200 so as to be twitched and displaced along the length direction of the rail portion 220 during manipulation.

In this way, the sleeve part 210 of the kit 200 can be leaned against the tooth gap T1, and the fork piece of the teeth picking section 120 of the long rod 100 can be manually inserted into the corresponding tooth gap T1, and can be bent to a certain degree of curvature. At the same time, the tip of the tongue located on the back side of the teeth T is used to swing and coordinate with the rear of the corresponding teeth, so that food residues can be completely drawn out to achieve the purpose of effective cleaning.

The above is an overview of the basic structure of the present invention and the assembly process of the components, and the functional principle and operation steps that the present invention can achieve are stated as follows:

Please refer to FIG. 5 , which is a schematic view of the interdental brush of the present invention during use and operation. The main operation method of the interdental brush of the present invention is that the user can first use fingers to pinch the holding section 110 of the long shaft 100 of the interdental brush, so that the tooth picking section 120 of the long shaft 100 is movably installed on the sleeve body 200 Cover part 210. Since the positioning portion 111 of the gripping section 110 has a certain hardness, one end of the gripping section 110 can lean against the rail portion 220 of the casing 200 and slide straight along the length direction of the rail portion 220 for use. Or smoothly manipulate the long rod 100 to twitch relative to the sleeve body 200 along its length direction. When the user manually manipulates the grip section 110 of the long pole 100 to push, the positioning portion 111 also has the function of preventing the sleeve 200 from being pulled and slipped out. Then, align one end of the sleeve portion 210 of the sleeve body 200 with the gap T1 that the user wants to clean. At this time, the fork structure portion 121 will be concentrated on the sleeve portion 210, and the thumb can push the holding section 110 continuously. Move the tooth-picking section 120 to extend into the gaps T1 of the teeth. At this time, the user can also operate the gripping section 110 to move it in and out quickly, so as to achieve the effect of cleaning the teeth T.

Please refer to FIG. 6 . FIG. 6 is a schematic diagram of the present invention extending into a larger tooth gap. In the present invention, because the width of the gap T to be cleaned varies according to the physiological structure and growth, some are smaller and some are larger, and the tooth-picking segment 120 of the present invention is also divided into a front end and a rear end. As shown in Figure 5, under the condition that the gap between the teeth is small, it is possible to utilize the thinner front end of the lower fork of the fork structure part 121 of the tooth picking section 120 beyond the other fork. The position is only about 30% of the width of the fork structure part 121, so it can extend into the smaller tooth gap T1. As shown in Figure 6, in the case of a large tooth gap T1, although the thickness of the rear part of the front end of the tooth picking section 120 is thicker, and the width is the width of the fork structure part 121, it can be inserted into the larger tooth gap T1 middle. In this way, the present invention is not only applicable to teeth gaps T1 of different sizes, but also perfectly achieves the effect of removing food residues, and is further applicable to a wider range of practical objects.

Please refer to FIG. 7 . FIG. 7 is a schematic diagram of the fork structure of the present invention located behind the teeth. In this embodiment, since the fork structure part 121 is made of soft plastic material, it will not cause damage to the corresponding gum T2 after being inserted into the tooth gap T1 to be cleaned, and each fork can be bent to a certain degree of curvature to the rear of the corresponding tooth T. In addition, since the surface of the fork piece of the fork structure part 121 is provided with rough particles 122, not only the tartar between the teeth gaps T1 can be brushed off by moving back and forth when extending into the teeth gaps T1, but also can be inserted into the teeth gaps T1. The rear of the teeth T1 is matched with the use of the user's own tongue tip to swing left and right behind the teeth T, thereby achieving the purpose of cleaning the tartar T3 behind the teeth T.

Please refer to Fig. 8 and Fig. 9, Fig. 8 is a schematic diagram of each fork sheet of the fork structure part 121 of the present invention withdrawn from the crimped state, and Fig. 9 is a schematic diagram of each fork sheet of the fork structure part of the present invention withdrawn Schematic diagram of brushing out in a concentrated state. If during use, each fork piece of the fork structure part 121 of the tooth-picking section 120 of the long rod 100 is normally in a straight state, due to the thinner thickness, it will not be able to effectively and comprehensively remove the teeth on the side of the tooth at the larger gap T1. of tartar. Since the fork structure part 121 of the present invention belongs to thin and flat soft material, it will change the fork pieces of the fork structure part 121 under stress due to the extrusion operation when cleaning the teeth T after using for a period of time. a twisted state. At this time, as shown in FIG. 8 , the fork structure part 121 is pulled back and concentrated in the sleeve part 210 of the sleeve 200 , so that the ability of the fork structure part 121 to resist lateral stress can be improved. As shown in Figure 9 and Figure 9-1, when the fork structure part 121 passes through the sleeve part 210 of the sleeve 200, it can concentrate the lateral force and then extend into the tooth gaps T1, the fork Each fork piece of the structure part 121 will automatically deform back to the twisted state, thereby increasing the distribution range of the fork structure part 121 in the space, thereby improving the roughness of the rough particles 122 on the fork structure part 121 touching the corresponding tooth gap T1. For the side of the teeth, the dirt on the details between the corresponding teeth T1 and the tartar on the side of the corresponding teeth T can be quickly removed by using the functional principle similar to that of a broom.

Please refer to Fig. 10, Fig. 10 is a schematic diagram of the tip operation of the present invention, the design of the tip 112 and the ball 113 of the holding section 110 of the long rod 100 is also for the user to block large food residues when encountering a large gap T1 case, another option is available. First use the pointed portion 112 and the ball 113 to pick out large food residues, and then use the fork structure portion 121 of the tooth picking section 120 of the long rod 100 to handle the fine residues, so that the user can completely remove all food residues.

To sum up, the design of the present invention is an interdental brush that can clean the teeth T in an all-round way. It mainly utilizes the sleeve part 210 to concentrate the fork structure part 121 of the flossing section 120 made of soft material to strengthen the fork structure part. 121 can resist the ability, and lean against the corresponding tooth gap T1, manually push the grip section 110 of the long rod 100 to extend the fork of the teeth picking section 120 into the corresponding tooth gap T1, and will not harm the user Patient's gingiva T2. At the same time, the tip of the tongue located on the back side of the teeth T can be used to swing, and the tip 112 and the ball 113 of the holding section 110 can also be used together to completely hook out food residues of all sizes. In addition, when each fork piece of the fork structure part 121 of the tooth-picking section 120 of the long rod 100 is transformed into a twisted state, the set 200 can still gather the fork structure part 121 and then insert it into the corresponding tooth gap T1, It can increase the chance that the rough particles 122 carried by it will touch the side surfaces of the teeth at the interdental gaps T1, and use these rough particles 122 to scrape off the side surfaces of the teeth T at the interdental gaps T1 and the teeth hidden behind the teeth T. Tartar, in order to achieve the purpose of effective cleaning.

Although the present invention has been described in terms of a preferred embodiment, those skilled in the art can make various changes without departing from the spirit and scope of the present invention. The above-mentioned embodiments are only used to illustrate the present invention, and are not intended to limit the scope of the present invention. All modifications or changes made without violating the spirit of the present invention belong to the patent scope of the present invention.
