Description

[0001] The present invention relates to a dual toothbrush having a toothbrush head rotated up and down.

The present invention relates to a dual toothbrush having a toothbrush head that is rotated up and down, and more particularly, to a dual toothbrush having a toothbrush head having a bristle on one side and an interdental toothbrush on the lower side thereof connected to a toothbrush handle by a hinge pin, The present invention relates to a dual toothbrush provided with a toothbrush head that rotates up and down about an axis of a hinge pin so that the bristles and interdental toothbrush can be easily changed.

In addition, an interdental toothbrush receiving space and an interdental toothbrush coupling groove are formed on an upper portion of the toothbrush handle, and an interdental toothbrush coupling protrusion is formed on an outer peripheral surface of the interdental toothbrush formed below the toothbrush head so that the interdental toothbrush coupling groove and the interdental toothbrush coupling protrusion are coupled to each other The present invention relates to a dual toothbrush having a toothbrush head rotatable up and down to prevent the interdental toothbrush from being contaminated when the toothbrush is held in the interdental toothbrush receiving space when brushing teeth.

Plaque is a colorless, continuous film of bacteria formed on the tooth surface, which causes toxins and free oxygen that breaks the gums, destroys the tissues surrounding the teeth, and causes inflammation of the gums, leading to periodontal disease.

Toothbrushes have been developed and used to effectively remove such plaque and prevent microbial-related diseases occurring in teeth and gums.

Background Art [2] Generally, a toothbrush is a tool that moves upward, downward, leftward, and rightward to clean teeth or gums, and includes a toothbrush body formed to handle a toothbrush, a toothbrush head provided at one side of the toothbrush body, A user holds the toothbrush body with his / her hand while holding a predetermined amount of toothpaste on the bristles, and puts the bristles into the mouth to move the teeth in various directions.

However, since a general toothbrush has a limitation in cleaning every corner of a tooth, an interdental toothbrush is used as a dental hygiene product specially designed to compensate for the limitation.

The interdental toothbrush is a small straight-line brush attached to the end of a straight handle to remove dental caries or plaque and prevent plaque from the interdental space, which is difficult to remove by toothbrushing or when there is a complicated restoration or correction device in the mouth, It is used to move between the teeth and move back and forth.

However, since the interdental toothbrush must be kept separately from the toothbrush, it is not easy to store the interdental toothbrush. In general, the size of the interdental toothbrush is so small that the interdental toothbrush is lost or dropped on the floor.

In addition, when a user using the interdental toothbrush is traveling or traveling, the toothbrush and the interdental toothbrush need to be separately stored and carried, which is inconvenient.

In order to solve the above problem, Korean Utility Model Registration No. 20-0220297 discloses a toothbrush incorporating an interdental toothbrush.
