Toothbrush of controlling wings of head}

The present invention relates to a toothbrush, and more particularly, to a toothbrush which is divided into a central portion and both wings, the head of the blade can be adjusted by the user can adjust the wing.

In general, the toothbrush is composed of a liquor portion formed by implanting the bristles on the handle and the tip toothbrush head of the handle, and the brush portion has a sufficient flatness and height to clean the entire tooth.

The function of the toothbrush is a tool having a function of physically removing contaminants attached to the teeth such as teeth or plaque. To effectively remove these contaminants, the bristles must reach every corner of the mouth and make physical contact with the tooth surface. As such, various methods have been attempted to ensure that the bristles reach every corner of the mouth.

The first method is to reduce the size of the head of the toothbrush. This method has the advantage of being able to easily enter a relatively small space due to the small size of the head, while the small number of bristles does not give the user a rich feeling when brushing and the amount of foam generated when used with the toothpaste There was a problem that the amount of brushing is reduced.

The second method is to form a portion of the bristles present in the head relatively higher than the other parts. This method is able to maintain a good feeling of brushing by giving a rich feeling and sufficient foaming when brushing, while the bristles can reach a relatively every corner, various kinds of products have been developed and sold.

The third method is to form a flexible part of the head so that the head can move flexibly according to the pressure applied when brushing.
