Electric toothbrush head

Abstract

An electric toothbrush head relates to an electric toothbrush for oral hygiene, in particular to the improvement of a double-rod sequential electric toothbrush head. The electric toothbrush head is characterized in that each drive rod, each gear and each boss are injection molded into a whole at one time through adopting an injection molding or casting, forging and pressing mode. The bristles of the brush head are respectively fixed on the rod at the front end of each drive rod through adopting a secondary injection molding or hot pressing, heat sealing and bonding mode; and the gear and the boss which are arranged on each drive rod are positioned at the inner side of a brush rod partition board in a brush head shell. According to the electric toothbrush head, the production and assembly processes are effectively simplified, the existing restriction factors of complicated structure, more fault points, worse safety, higher production cost and the like which influence the large-scale production and use of the double-rod sequential electric toothbrush head in the assembly mode are overcome, and the low-cost and large-scale production of an enterprise are facilitated. The hidden troubles that the bristles are fell off and the bristles and the front parts of the drive rods are separated from the partition board of the drive rods are eliminated, so the use safety is improved.

Description

technical field [0001] An electric toothbrush head relates to an electric toothbrush for oral cavity cleaning, in particular to an improvement on the head of a double-rod sequential brush electric toothbrush. technical background [0002] With the improvement of people's quality of life, people pay more and more attention to oral cleaning, especially the cleaning and protection of teeth, which has been promoted to the level of health preservation and prevention of related diseases.

Problems solved by technology

There is also a "curved arm double rolling brush electric toothbrush", its brush head structure is more complicated, and the brush head is too large, which is not conducive to the movement of the brush head in the oral cavity

The complex structure of the brush head will increase the corresponding production process links, increase the production cost, and also significantly increase the failure points of the brush head, which is also not conducive to the widespread use of people
