Description

Rotary Toothbrush {ROTARY TOOTHBRUSH}

The present invention relates to a rotating toothbrush. More particularly, the present invention relates to a rotating toothbrush comprising an L-shaped rotatable hinge as rotating means.

In recent years, as life has been improved and interest in health has been heightened, a lot of attention has been paid to tooth health. Various toothbrushes have been developed and used because it is known that prevention of dental health is more effective than treatment.

The toothbrush is an oral appliance used for brushing teeth by applying toothpaste to toothbrush bristles to remove food residues and plugs existing in the teeth. It removes plaque buried on the surface of teeth, teeth, gums or tongue, .

Generally, a toothbrush used in a toothbrush includes a handle and a head with a bristle root. However, when the toothbrush is wiped with a toothbrush, toothbrushing is performed in the lateral direction, so that not only the foreign substances and pragees between the teeth are completely removed but also the enamel is easily damaged and becomes a main cause of tooth diseases.

In order to prevent this, it is recommended to use toothbrushing from the gums when brushing teeth, but it is difficult to move the toothbrush vertically in a structured manner, so it is customary to brush the toothbrush in the left and right direction, There is a problem that it can not be prevented.

In addition, since the brushing is repeatedly performed up, down, left, and right, the movement of the wrist joint is required so that the wrist joint may be easily damaged.

In order to solve such a problem, Patent Document 1 proposes a technique related to a rotating toothbrush.

In the rotating toothbrush proposed in Patent Document 1, a hemispherical shape of a semi-circular shape (2D) is connected to one end by an intermediate mandrel (2C), two through holes (2B) are formed around its periphery, (2); And an idle shaft 3 A extending to the circular cap 2 through the intermediate mandrel 2 C and a shaft 2 A extending from the idle mandrel 3 A are provided at one end of the idle shaft 2 A, An elongated elliptical bristles 3; The handle front cap 1 inserted into the circular cap 2 is provided with both ears 1B connected to the leaf springs so as to be inserted into and fixed to the through holes 2B. A toothed wheel 1D is provided on the outer periphery of one end of the quadrangular rotating mandrel 1A and the tooth 4A is formed on the toothed wheel 1D, (See Fig. 1) in which the tooth rods 4B with the teeth 5 formed thereon are engaged and fixed in the vertical direction.

However, in the case of the rotating toothbrush proposed in the above Patent Document 1, it is designed to be rotatable while maintaining the straight shape as it is, and it is not possible to brush the entire corner of the mouth, and the number of times of wrist use for repetitive brushing is drastically reduced There is a problem that efficient toothbrushing for dental health is not achieved.

On the other hand, there is a limit in which it is difficult to clean every corner of the tooth with the toothbrush alone, and in recent years, in addition to wiping the teeth with a toothbrush, various supplemental oral hygiene products have been purchased and used.

The interdental toothbrush is a tool for efficiently removing food waste, which is a foreign material that can not be easily removed by a general toothbrush between a tooth and a tooth, or plaque, which is a bacterial dental plaque, It is common to use the brush while holding the body of the interdental toothbrush and repeatedly pushing and pulling the brush into the space between the tooth and the teeth.

Although the conventional interdental toothbrush is generally used in parallel with the toothbrush, the toothbrush needs to be separately stored with the toothbrush, so that it is very troublesome and hygienic management is difficult when stored separately.

Accordingly, there is a pressing need for a toothbrush that is more efficient for the user's teeth health, minimizes the use of the user's wrist, and allows the interdental toothbrush to be used in parallel with toothbrushes that are essential for tooth health.
