The present invention relates to a toothbrush head, and more particularly, to a toothbrush head of a new type that can be easily wiped even the difficult to clean with a general toothbrush head, such as the molar front portion, the gum massage effect.

Effective plaque removal is one of the most important factors for maintaining healthy teeth. For effective plaque removal, the toothbrush reaches all areas such as the tooth surface or the molar and between the tooth and the interdental area, so that the toothbrush can be effectively brushed and the hair bundles act differently when brushing the tooth surface or brushing the molar and gums. The most efficient removal of plaque is possible. In other words, the inner part of the oral structure with the molar is narrow, so that the bristles planted in the toothbrush head should have a different shape accordingly.

However, since most of the conventional toothbrushes are made of toothbrush head bundles only in a circular shape (see above), there is an unreasonable point that the same cleaning effect is obtained for each part of the tooth and thus the above-mentioned effective brushing is not performed. Thus, in addition to the conventional toothbrushes, toothbrushes have been developed to make the bristle shape at the tip angle of the bristles bristles or at the inclined angle in the direction of the toothbrush bar to effectively work when molar teeth are brushed. However, these toothbrushes are effective for brushing the upper teeth of the molar but not for brushing the teeth, and the head shears of these toothbrushes are not as durable as conventional flat bristles, so they are easily spread out and thus cannot be used for a long time. Had In addition to the toothbrushes mentioned above, toothbrushes made of V-shape or concave-convex shape with the bristles sideways likewise mentioned above effectively act on all teeth and gums as mentioned above when the user brush their teeth. It is unreasonable in terms of maintaining healthy teeth by removing or brushing teeth.

Therefore, the present invention has been created to solve the above problems, the object of the present invention is to form a different shape on each part of the toothbrush head to be effective brushing at each position in wiping between the upper and side surfaces of the tooth and the tooth. The present invention provides a new type of toothbrush head in which an auxiliary hair bundle is placed at an appropriate position so that the bristles of a toothbrush can be planted and the inclined hair bundle can be prevented from being easily opened.

In order to achieve the above object, the present invention is a toothbrush head in which various types of hair bundles are planted on the woolen surface, the front end of the woolen surface is inclined forward 5 to 15 degrees with respect to the waterline on the woolen surface A plurality of warp hairs are planted, and a plurality of annular hairs are planted around the round hairs around the dome part of the hair-planting surface which is separated from the front end, and on the left and right side ends of the hair-planting surface. A plurality of soft elastic bodies are planted, and a toothbrush head is characterized in that a flat hair bundle is planted in the middle portion between the front end portion and the dome portion and the rear end portion behind the dome portion.

Here, the inclined hair bundle is characterized by consisting of two crescent-shaped inclined hair bundle and one circular inclined hair bundle from the front.

In addition, the middle portion is characterized in that a plurality of straight auxiliary hair bundles and a circular auxiliary hair bundle is planted on the left and right sides of the flat hair bundle.

In addition, the rear end is characterized in that a plurality of straight and circular auxiliary hair bundles are planted on the left and right sides of the flat hair bundle.

In addition, the soft elastic material is EPDM rubber, SEBS rubber or silicone rubber material, characterized in that the horn shape of 2.0 to 4.0 mm, 0.5 to 2.0 mm in length, 5 to 10 mm in height, respectively.

The dome has a diameter of 5 to 15 mm, and a height difference between the round circular bundle located at the center and other bundles is 1.0 to 3.5 mm at maximum.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. While many specific details, such as the following description and the annexed drawings, are shown to provide a more general understanding of the invention, these specific details are illustrated for the purpose of explanation of the invention and are not meant to limit the invention thereto.
