Curved-face toothbrush head and toothbrush

Abstract

The invention provides a curved-face toothbrush head and a toothbrush, and relates to the technical field of toothbrushes. The curved-face toothbrush head comprises a toothbrush head base, the side-looking direction of the toothbrush head base is arc-shaped, a concave face of the toothbrush head base is a bristle-planting face, the bristle-planting face is provided with a plurality of layers of step faces gradually elevated from middle to two sides, each layer of step face is provided with at least one row of bristle planting holes, toothbrush bristles are planted in the bristle planting holes, and the brush face of the toothbrush bristles is in the shape of an arc with the radian being the same as that of the toothbrush head base. The plurality of layers of step faces gradually elevated from middle to two sides are arranged on the bristle-planting face of the curved-face toothbrush head base, the bristle planting holes are arranged in the step faces, so that the hole face of each holeis arranged on the horizontal plane, then an existing bristle-planting machine can realize the bristle planting work on the curved-face toothbrush head, therefore, the problem that the bristle planting on the curved face is difficult is overcome, the radian of brush bristle distribution can be better controlled, and the tooth-brushing feeling completely different from that obtained by using a plane brush head can be formed.

Description

technical field [0001] The invention relates to the technical field of toothbrushes, in particular to a curved toothbrush head and a toothbrush. Background technique [0002] In the prior art, there are two schemes for forming curved bristles: 1) keep the base of the toothbrush straight, and only achieve the effect of bristles forming a curved surface by grinding the ends of the bristles (especially nylon filaments); Hole depth, decrease the brush hole depth from the middle to both sides, so that the effect of bending the brush surface can be achieved after implanting bristles of equal height. [0003] For the first molding solution, the curved surface effect is only achieved through grinding. The ends of the polished nylon filament bristles are square and have edges and corners, which will affect the brushing feeling and wear teeth to a certain extent. At the same time, since the bottom surface is flat and the brush surface is curved, the height of each bristle is not equa...

AI Technical Summary

Problems solved by technology

[0003] For the first molding solution, the curved surface effect is only achieved by grinding. The end of the polished nylon filament bristles is square and has edges and corners, which will affect the brushing feeling and wear teeth to a certain extent.

At the same time, since the bottom surface is flat and the brush surface is curved, the height of each bristle is not equal, which will cause the force of each bristle to be different when brushing, so the brushing feeling is not good.
