Description

Toothbrush head {TOOTHBRUSH HEAD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush head, and more particularly, to a toothbrush head capable of effectively removing plaque between the teeth and teeth and easily wiping the back of the molar which is difficult to reach by the toothbrush.

In general, a plaque is a sticky, transparent film that sticks to the surface of a tooth, also called a plaque. Plaques are made up of many germs (bacteria) living in the mouth clinging to certain components in saliva, and also in teeth, prostheses, orthodontic appliances, dentures and their surroundings.

The bacteria in the plaque not only damage the gums by creating toxins and free oxygen, but also damage the teeth and surrounding tissues. When the teeth and gums are damaged, they become swollen, bloody, and bad breath. In particular, plaque accumulation in the periodontal pouch caused by the gap between the teeth and gums damages the bone supporting the tooth, and in the worst case, the tooth is lost.

Therefore, it is necessary to remove plaque by usual brushing. In order to effectively remove plaque, it is necessary to remove all of the plaque (tooth surface, tooth surface), tooth (between cervical tooth and gum), interdental (between tooth and tooth) The bristles must reach the area.

However, since conventional bristles are uniformly formed of a bundle of bristles having a round cylindrical structure or a bundle of bristles has a uniform arrangement pattern, the tooth cleaning ability is excellent, but the plaque cleansing force and the interdental penetration force are poor and the plaque can not be effectively removed.

To solve this problem, a brush bristle bristle structure of a toothbrush having a triangular bristle bundle and a rhombic bristle bundle has been proposed (Korean Utility Model Registration No. 20-0306545 (Feb. 25, 2003)). However, such a conventional bristle bristle brushing structure, And it was not suitable for general use.

Accordingly, there is a need for a design of an appropriate bristle shape and arrangement that can effectively remove plaque from the teeth and teeth, even if brushing is performed in various ways.

Korean Utility Model Registration No. 20-0306545 (February 25, 2003)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the accompanying drawings, embodiments of the present invention will be described in detail. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, the toothbrush 1 includes a handle 100 that is elongated in one direction and a head 200 that is integrally formed on the tip of the handle 100. The handle 100 includes a head 200, The handle 100 is a portion held by the user, and the head 200 is a portion where the bristles 300 are worn.

The handle 100 and the head 200 may be formed of a material selected from the group consisting of polypropylene, polyethylene, polyethylene terephthalate, polycyclohexylenedimethylene terephthalate, saturated polyester resin, polymethylmethacrylate, cellulose propionate, polyurethane, Acrylonitrile, butadiene, styrene), and the like. Further, the handle 100 may be partially or wholly applied with a flexible resin such as an elastomer in order to improve gripping property and prevent slippage.

The bristles 300 are comprised of a plurality of tufts 310 to 350 that are worn on the wicking surface 210 of the head 200. The bundles of filaments 310 to 350 are bundles of filaments and are folded into a U-shape. A fixing member (not shown) is sandwiched therebetween. do. The filaments 310 to 350 may be bundled into a shape such as a polygon, an ellipse, or a rectangle such as a triangle or a quadrangle. Also, in this embodiment, it is exemplified that the bundle bundles 310 to 350 are fixed by using a fixing piece, but it goes without saying that it can be fixed by a heat fusion bonding method.

The material of the bristles 300 may be selected from the group consisting of polyamides (6-12 nylon, 6-10 nylon), polyesters (polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate), polyolefins (polypropylene) Olefin-based, and styrene-based), and the like.

The filament constituting the bristles 300 may have a polygonal cross section including a circle or a triangle, and the ends may be hemispherical or tapered.

Referring to FIGS. 1 to 3, a bristle 300 implanted in a toothbrush head according to an embodiment of the present invention will be described.

The bristles 300 include a first tuft 310 for cleaning the rear side of the molar teeth that is difficult for the toothbrush to reach, a second tuft 320 for cleaning the rear side of the front teeth and the canines, Three tufts 330 and a fourth tuft 340 for effectively removing plaque between the teeth and teeth.

The first to fourth pattern bundles 310 to 340 of the present embodiment are formed of a plurality of unit patterns (one pattern block), and the unit patterns are arranged so as to have a constant pattern, and have the above-described functions. In other words, the first model bundle 310 is arranged such that the unit model feet of the fan shape are arranged in a semicircular pattern, and the second model bundle 310 is a semicircular pattern in which the unit model feet of the fan shape are symmetrical with the first model bundle 310 Respectively. In addition, the third pattern 330 is arranged such that a unit model of a polygon forms a long rectangular pattern, and a fourth model bundle 340 is arranged in a zigzag pattern of a unit model of a circle.

In addition, the first to fourth hair bundles 310 to 340 of the present embodiment have the following area ratios. Assuming that the area of the fourth hair bundle 340 is 1, the area of the first and second hair bundles 310 and 320 is 1.5 to 2.5 and the area of the third hair bundle 330 is 3 to 6.

That is, the fourth model bundle 340: the first and second model bundles 310 and 320 = 1: 1.5 to 2.5

Fourth strand (340): Third strand (330) = 1: 3 to 6

When the first to fourth hair bundles 310 to 340 are arranged at the above-mentioned ratios, the back of the molar teeth, the back of the molar, and the back of the canine can be easily cleaned, and plaque of teeth and teeth can be effectively removed.

The first hair bundle 310 is positioned at the front end of the hair styling surface 210 so as to remove the plaque attached to the back of the molar. In addition, the four unit patterns 312 to 318 constituting the first pattern 310 are arranged in a semicircular pattern so as to cover the elliptical molar teeth. That is, the four unit patterns 312 to 318 are radially arranged around a point to form a semicircular pattern.

The four unit modules 312 to 318 have a fan shape extending toward the outer side in order to prevent the first hair bundle 310 from lying forward in the process of cleaning the molar teeth. In other words, when the toothbrush 1 is tilted to clean the rear side of the molar teeth, the first hair bundle 310 is pressed and easily deformed.

The second hair bundle 320 is positioned at the rear end of the wedge surface 210 so as to remove plaque attached to the back of the canine and the canine. In addition, the three unit patterns 322 to 326 constituting the second pattern 320 are arranged in a semicircular pattern symmetrical with the first pattern 310.

The second pattern 320 of the above-described pattern can be brought into contact with the front teeth and the canines in a large area when brushing teeth, and at the same time, the plaque accumulated on the rear concave portion of the front teeth can be effectively removed.

The third tuft 330 is positioned at the center of the wedge surface 210 to remove plaque attached to the tooth surface. The third pattern bundle 330 is arranged such that the two unit pattern bundles 332 and one unit pattern bundle 334 are alternately arranged in the left and right directions to form a long rectangular pattern. At this time, the unit cells 332 and 334 are formed into polygons (square in this embodiment).

The third pattern 330 of the above-described pattern is arranged such that a plurality of unit patterns 332 and 334 are arranged in an elongated pattern so that even when the head 200 moves in either the forward, backward, left, And the tooth surface can be effectively cleaned.

The fourth hair bundle 340 is for removing plaque accumulated on teeth and teeth, and is formed of a pair arranged on both sides of the third hair bundle 330. The unit patterns 342 and 344 of the fourth pattern 340 are arranged in a zigzag pattern that is spaced apart in the front and back direction and is adjacent to the third pattern 330 or spaced apart from the third pattern 330 . At this time, the unit cells 342 and 344 are formed in a circular shape.

The fourth pattern 340 of the above-described pattern has a plurality of unit patterns 342 and 344 arranged in a zigzag pattern. Since the unit patterns 342 and 344 can be closely attached to the surface of the rugged teeth and are inserted deep into the teeth, The plaque can be effectively removed.

On the other hand, the bundles 310 to 340 of the bristles 300 may be formed to have different lengths. For example, the first to third mold bundles 310 to 330 may be formed longer than the fourth mold bundle 340. More specifically, the first to third mold bundles 310 to 330 may be formed to be 0.5 to 3.0 mm longer than the fourth pattern bundle 340.

When the first and second hair bundles 310 and 320 are formed long, the back of the molar teeth and the back of the canine can be easily cleaned. In addition, when the third hair bundle 330 is formed long, it is more protruded than the surrounding hair bundle (the fourth hair bundle 340), so that it can be effectively contacted with the tooth surface.

On the other hand, when the fourth hair bundle 340 is formed to be short, it is possible to prevent the wear of the cervical part by reducing the stimulation by the hair bundle 340 when brushing the hair. Further, when the head 200 is moved up and down to brush the teeth, the hair bundle 340 can be cleaned to the corners of the teeth, thereby preventing plaque from accumulating in the teeth.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Those skilled in the art will understand.
