Description

Toothbrush {TOOTH BRUSH}

The present invention relates to a toothbrush, and more particularly, to a toothbrush composed of a combination of a first toothbrush unit and a second toothbrush unit, wherein the shape and angle of the bristles can be adjusted in various ways by configuring the second toothbrush unit to be rotated and moved. it's about

The bristles of the toothbrush are basically configured to clean the tooth surface, and are generally arranged at a uniform height.

In the case of some functional toothbrushes, the bristles are arranged to clean every corner of the teeth by varying the height of the bristles, but there is a limit to completely removing food remaining between the teeth and gums.

In addition, in the case of an interdental toothbrush, since it cannot be used for general tooth brushing, it is inconvenient to have it separately from a general toothbrush. There is a problem that there are many cases where the gums are damaged by contact with the teeth.

A technical problem to be achieved by the present invention is to provide a toothbrush that can adjust the shape and angle of bristles in various ways by configuring the second toothbrush portion to rotate and move in a toothbrush composed of a combination of a first toothbrush portion and a second toothbrush portion.

A toothbrush according to an embodiment of the present invention includes first bristles arranged such that an empty area exists therein, and includes a first toothbrush portion and a second bristles having an insertion portion formed in a body, and a body of the first toothbrush portion and a second bristle. A second toothbrush unit configured to be rotationally movable around the connected connection point, wherein the second toothbrush unit is inserted into the insertion unit in a first direction so that the second toothbrush bristles are disposed in the empty area and rotated. As it moves and is fixed in the second direction, the second bristles may be spaced apart from the first bristles and disposed at an independent position.

Depending on the embodiment, the first bristles may be arranged along the edge of the head of the first toothbrush unit.

Depending on the embodiment, the insertion part may be formed such that the second toothbrush part can be inserted in the first direction or the second direction.

According to an embodiment, the insertion part is formed so that both the head and the body of the second toothbrush part are inserted in the first direction, and only the body of the second toothbrush part is inserted in the second direction. can

Depending on the embodiment, the thickness of the body of the first toothbrush unit may be formed to be relatively thicker than the thickness of the body of the second toothbrush unit.

Depending on the embodiment, the second bristles of the toothbrush may be arranged in a line on the head of the second toothbrush unit.

According to an embodiment, in a state in which the second toothbrush unit is rotated and inserted into the insertion unit in the first direction, the first and second bristles are used as a general toothbrush together, and the second toothbrush unit is rotated and moved. Thus, in a state in which the bristles are fixed in the second direction, the second bristles may be used as an interdental brush.

Depending on the embodiment, the first bristles may be formed with relatively lower strength than the second bristles.

Depending on the embodiment, the connection point may further include an angle adjusting member that allows the second toothbrush unit to be fixed in the second direction according to an angle selected from among a plurality of angles.

Depending on the embodiment, while the second toothbrush unit is fixed in the second direction, the upper surface of the head of the first toothbrush unit and the upper surface of the head of the second toothbrush unit may face different directions.

Devices according to embodiments of the present invention have the effect of adjusting the shape and angle of the bristles in various ways by configuring the second toothbrush unit to rotate and move in a toothbrush composed of a combination of the first toothbrush unit and the second toothbrush unit.
