A kind of toothbrush and its manufacturing process

Abstract

The invention discloses a toothbrush. Top clamping holes are formed in top ends of bristles, side clamping holes are formed in side walls of the bristles and arranged on a gradual rising curve along the side walls of the bristles from bottom to top, and projection of the curve in the vertical plane is a tangent curve. A manufacturing process of the toothbrush comprises steps as follows: firstly, the outer side wall of each glass fiber is covered with a silica gel layer, and a hemisphere made of silica gel is formed at the top of the glass fiber; then, small airways are punched in the axial direction of the corresponding glass fibers, and the side clamping holes and the top clamping holes are engraved in the silica gel layers with a miniature engraving process and then communicate with the small airways; finally, each bristle is connected with a brush head in a sealed manner, and the small airways communicate with a large airway. The toothbrush has the advantages that when toothpaste with abrasive materials is used, the abrasive materials can be clamped into holes in the bristles and better polish teeth; besides, the side clamping holes in the side surfaces of the bristles are arranged along the curve, the teeth can also be effectively polished when the side walls of the bristles are contacted with the teeth, and accordingly, the polishing effect of the teeth is greatly improved.

Description

technical field [0001] The invention relates to a toothbrush and a manufacturing process thereof. Background technique [0002] Toothpaste and toothbrush are commonly used toiletries in people’s daily life. The existing toothpaste is mixed with abrasives. When using an ordinary toothbrush, the abrasive is in an indeterminate state and grinds the surface of the teeth through the extrusion between the bristles and the teeth. The way the abrasive does not play a big role, and the use efficiency of the abrasive is low. Contents of the invention [0003] The object of the present invention is to provide a toothbrush and its manufacturing process, which can effectively solve the problem of low efficacy of the conventional toothbrush and the abrasive in the toothpaste. [0004] In order to solve the above-mentioned technical problems, the present invention is achieved through the following technical solutions: a toothbrush, including a brush handle, a brush head and bristles, th...
