In addition, the bristles are characterized in that the planting is fixed to the head by a plurality of triangular prism or triangular shaped fleece.

In addition, the bristles are characterized in that one end is planted to be fixed to the head by a round cone-shaped fleece.

According to the toothbrush of the present invention, the bristles are inclined to the toothbrush head so that the bristles do not orthogonally touch the teeth or gums so that the teeth or gums are not damaged when brushing.

In addition, the bristles are aligned in a concave curved shape to the shape of the teeth or dents, so the area of contact between the bristles and the teeth or gums is increased, the brushing is not only good, but also the time required for brushing.

Hereinafter, a toothbrush according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 and 2, the toothbrush 100 according to a preferred embodiment of the present invention includes a head 110, a handle 120 and a neck 130.

The head 110 is for planting the bristles 140, and has a round disc shape to facilitate brushing in and out of the user's gums.

In the head 110, a number of bristles 140 are inclined at a predetermined angle so as to face outward, and the center of the head 110 is empty. The inclination angle α of the bristles 140 is 30 ° to 89 °, preferably 30 ° to 60 ° and most preferably 40 ° to 50 ° with respect to the surface of the head 110. When contacted almost orthogonally to the brush head, the bristles cause the teeth to be bounced diagonally. This can prevent damage, such as tooth wear or gum retraction, which can prevent the tooth from weakening or becoming cold. In addition, when the bristle 140 is inclined, the bristles inclined in a reverse direction with respect to the advancing direction serve to pick teeth or gums like toothpicks, and the bristles inclined in a forward direction serve as a broom.

In the present embodiment, the bristles 140 are not planted near the center of the head 110, but alternatively, the bristles 140 may be planted on the entire front surface of the head 110 including the center. The bristle 140 is not only inclined outward as described above, but is aligned to have a concave curved shape to match the shape of the teeth or teeth having convex curved shapes. In this case, when brushing the entire bristle 140 is in contact with the teeth or gums, the contact area becomes very large compared to the prior art. Therefore, not only brushing is easy but also the time required for brushing is greatly reduced. In addition, the force applied to the head 110 by the user is almost evenly transmitted to the teeth or gums through the bristle 140, there is no damage to the teeth or gums.

In order to align the tips of the bristles 140 in a concave curved shape, the length of the bristles may be increased from the inside to the outside by varying the length of the bristles.

The handle 120 is for holding by the user and is made to be easily operated by the user while maintaining comfort.

Neck 130 is for connecting the head 110 and the handle 120, is made thinner to have more flexibility than the handle 120.

3 and 4 exemplarily show how the bristles 140 are planted in the head 110.

On the front of the head 110, a large number of hair follicles 111 are formed in a ring-shaped peripheral region excluding the central circle region. The hair follicles 111 may be formed at regular intervals or may be formed at other intervals.

The bristle 140 is planted in the hair follicle 111 so that the center thereof is folded by the triangular prism-like fleece 113 shown in detail in FIG. 5. The hair piece 113 is formed to be somewhat smaller than the hair follicle 111 so that the bristle 140 does not fall out of the hair follicle 111 when being forcibly inserted into the hair follicle 111 together with the bristles 140. In the present embodiment, the hair piece 113 is formed in a triangular prism shape, but alternatively, the bristles may be formed in a triangular weight shape so that the bristles spread in all directions.

In the present exemplary embodiment, the surface of the head 110 is flat, but as illustrated in FIGS. 6 and 7, the surface of the head 110 may be convexly formed in a dome shape. In this case, the bristles 140 'are implanted almost orthogonally to the dome-shaped surface by the thin rectangular fleece 113', but the ends thereof have a concave curved shape as in the previous embodiment. In this way, the device can be applied to the bristles are inclined to the head inclined to the current brush bristles as it is can be very economical.

Meanwhile, the bristles 140 may be planted on the head 110 by using one fleece 113 "as shown in FIG. 8. The fleece 113" may have a rounded end as shown in FIG. 9. It has a conical shape, and one hair follicle 111 "corresponding to or slightly larger than the hair piece 113" is formed in the head 110 near the center. In this way, near the center of the head 110 is empty, the bristles 140 are planted only in the annular peripheral area. Unlike the previous embodiment, the bristle is very easily planted on the head, thus lowering the manufacturing cost and reducing the manufacturing time.

In the above-described embodiments, the head of the toothbrush is designed to have a disc shape. Alternatively, the toothbrush may have a rounded rectangular plate shape, an elliptic plate shape, or a track plate shape. In addition, although the surface of the head is designed to be flat, it may be designed to be convex or concave.

Although the toothbrush of the present invention has been described above with reference to preferred embodiments, it will be apparent to those skilled in the art that various changes, modifications, or variations are possible without departing from the spirit of the present invention.
