Description

Electric Toothbrush

The present invention relates to an electric toothbrush, and more particularly, in a linear reciprocating manner, the tips of the bristles are vertically reciprocated by the linear reciprocating motion of the driving plate and reversibly displaced vertically with the driving shaft, thereby rubbing up and down with the teeth. Not only can you clean your teeth up and down, but also the structure is simple and robust by the crank drive, which reduces manufacturing costs, reduces the risk of breakdowns, makes repairs easier and improves durability greatly. It is an electric toothbrush that can be replaced easily can significantly reduce the cost.

In general, ingestion of food is to brush the teeth for the cleanliness of the teeth, the convenience, efficiency and durability of toothbrushes are frequently used.

Electric toothbrush is used a lot because of the convenience of this toothbrush, foreign matter of the tooth is easier to remove and convenient than manual.

However, in the conventional electric toothbrush, the bristles brush the teeth by rotating the bristle base unit by the driving of the motor. In the electric toothbrush of this structure, the brushing efficiency is determined by the time and the contact area of the tooth when the bristles are rotating. This is decided.

In order to increase the contact time and area of the bristles, the rotation radius of the bristle base should be increased. In order to increase the rotation radius, the conventional electric toothbrush needs to double the size of the bristle base and the housing size becomes larger. There was a difficulty in brushing the teeth because it was difficult to insert the housing into the mouth of the user.

This rotation method has a problem that can not optimally clean the teeth, such as the bone is not polished due to the tooth structure is formed up and down the bone.

In addition, there is a problem that the bristle is brushed by the bristle at high speed when brushing teeth can be separated from the bristle by centrifugal force and introduced into the oral cavity.

In addition, since the bristle base unit and the housing are integrally formed, there is a problem that the whole housing must be replaced when the bristle is replaced.

In addition, the structure is complicated and there are a lot of components difficult to repair in case of failure, there is a problem that a number of parts are used only once and discarded because there is no choice but to replace with the housing when the bristle is frequently used.

The present invention is to solve the conventional problems as described above, by cleaning the teeth in a straight reciprocating method with the upper and lower friction can be optimally cleaned teeth can not only increase the efficiency of brushing, but also simplify the structure manufacturing costs The purpose is to provide an electric toothbrush that can reduce economic losses by reducing and allowing bristle to be replaced by only the bristles.
