Description

[0001] Multipurpose toothbrush [0002]

The present invention relates to a multi-purpose toothbrush. More particularly, the present invention relates to a multi-purpose toothbrush capable of being foldably connected to a body, The present invention relates to a toothbrush which can be conveniently used for various purposes according to the necessity and selection of a toothbrush, and is easy to carry and store.

In general, toothbrushes and toothpaste-based brushes are intended to prevent tooth decay. The core of tooth health is prevention of gum disease rather than tooth decay. The leading cause of gum disease is the plaque (food waste, plaque) that causes germ infection on the gums.

In other words, plaque usually develops into tartar if it is not removed within 48 hours, and stuck to the tartar to cause bacterial infection in the gum. It is very difficult to completely remove food waste or plaque, as toothbrushes do not clean the space between the teeth or the exposed root bifurcation, even if the toothbrush is maintained for a long period of time to maintain healthy teeth. If the bristles are scratched as if scratched between the teeth, the bristles fall and widen, shortening the life of the toothbrush.

Toothbrushes and dental floss are widely used as an adjunct to prevent gum disease by eliminating plaque and preventing plaque formation, stimulating the gums to improve gum health, and improving surface keratinization and blood supply.

Recently, a toothbrush capable of using the interdental toothbrush and the floss in parallel has been proposed.

For example, a portable toothbrush equipped with an interdental toothbrush is disclosed in Korean Utility Model Registration No. 20-0437910.

1 and 2, an auxiliary body 30 for storing the interdental toothbrush 40 is formed on one side of the main body 10 having the first containing portion 11 for storing the toothbrush 20 A mirror 13 is provided on the front surface of the main body 10 so as to wipe the teeth between the teeth with the naked eye by using the interdental toothbrush 40 and a pocket hanger 12 is formed on the rear surface of the main body 10 Lt; / RTI >

However, since the conventional portable toothbrush can be used by selecting the interdental toothbrush 40 as required by the user, the interdental toothbrush 40 is simply stored in the auxiliary body 30 and stored. Therefore, When the toothbrush 20 is used as the toothbrush 20 due to the volume and space of the auxiliary body 30, it is very inconvenient for the user to simultaneously grasp the main body 10 and the auxiliary body 30, In addition, there is a problem of occupying a lot of space when carrying.

As another example, Korean Utility Model Registration No. 20-0334842 discloses a toothbrush capable of selectively attaching and detaching one of a bristle portion, a floss portion, a tongue cleaning portion, and an interdental toothbrush portion to each of both sides of a hollow handle This is because the user needs to replace the bristles part, the floss part, the tongue cleaning part, and the interdental toothbrush part one by one according to the necessity and use, so that it is cumbersome to use and there is a limitation that portability and storage are considerably inconvenient.
