Abstract

Disclosed are a toothbrush and a method making the same. The toothbrush includes a handle including a handheld portion and a brush head portion, and a cleaning member fixedly connected with the brush head portion. The cleaning member includes a plurality of bristles and a bristle plate formed by integral melting of the bottom of the plurality of bristles and is fixedly connected with the brush head portion. The bristles are closely arranged and the bottom thereof is melted to form the bristle plate, with the unmelted portions erected on the bristle plate. The integral adhesion force of the bristles is enhanced, and the cleaning area between the bristles and the teeth is increased, thereby facilitating cleaning of the teeth. The toothbrush features a simple process of manufacturing and low costs.
