When tongue removal is done, the tongue may be damaged, and when brushing teeth, the tongue removal blade 21 may scratch the ball, and the overall structure is complicated, so even when the toothbrush is cleaned, the removed tongue remains hygienic. There were many problems such as concern.

The present invention is to solve the problems of the prior art as described above, the tongue removal portion formed in the U-shaped with a soft material such as silicone, natural and synthetic rubber on the bristle of the head of the toothbrush, and the inside of the tongue removal portion Digging a lower height than the outside to form a tongue accumulation area, the tongue removal portion is 0.1 to 2mm in height, the tongue accumulation portion is treated so that the entire round so that the tongue is not deposited, hygiene without brushing hygiene The purpose of the present invention is to provide a toothbrush-using toothbrush that can combine the brushing and the tongue removal function, which can remove the tongue well without hurting the tongue when the tongue is removed.

It is still another object of the present invention to provide a method for producing a tongue cleaner combined toothbrush which forms a tongue removing portion of a soft material such as silicone, natural and synthetic rubber, on a toothbrush made of a hard material such as general PP, PE, or PET. .

Tongue cleaner combined toothbrush according to the present invention,

A handle, a head, bristles formed on the head, a tongue removal portion formed in a U shape with a soft material such as silicone, natural and synthetic rubber on the back of the bristles of the head, and the inside of the tongue removal portion is higher than the outside. The lingual accumulation part is formed by digging low and collecting the tongue.

The tongue removal portion is preferably a height of 0.1 to 2mm.

The tongue collected portion is preferably rounded so as not to deposit the tongue.

In addition, the manufacturing method of the tongue cleaner combined toothbrush according to the present invention,

And forming a tongue collecting portion and tongue removing portion attaching position, and attaching the tongue removing portion of the soft material by injection molding to the tongue removing portion attaching position.

Hereinafter, with reference to the drawings will be described in detail. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

Figure 1a is a perspective view of the toothbrush before forming the tongue removal portion (30 in Figure 2a) according to the present invention.
