Description

[0001] The present invention relates to a toothbrush capable of adjusting the angle of a wing portion of a toothbrush,

The present invention relates to a toothbrush capable of adjusting the angle of a head of a toothbrush. More particularly, the present invention relates to a toothbrush comprising a toothbrush head and a neck formed integrally with a lower end of the toothbrush head, And the neck portion is composed of a transversely folded portion, a flat portion and an unfolded portion. When the angle adjusting portion is forcibly moved to the folded portion by engaging with the neck portion by forming an angle adjusting portion having a rectangular parallelepiped shape groove at the end of the toothbrush handle, The present invention relates to a toothbrush capable of adjusting the angle of a head of a toothbrush so that bristles on both wing portions of the toothbrush head are formed to face the central portion and the bristles are densely packed so as to effectively remove plaque between the teeth.

In addition, when the angle adjusting portion is moved to the unfolding portion, the bristles of both wing portions of the toothbrush head are formed to be directed to the outside of the central portion, thereby widening the density of the bristles and effectively removing the plaque of large teeth such as molar teeth. The present invention relates to a toothbrush capable of adjusting the angle of the head wing.

The oral cavity is the starting point of the digestive organs. It uses teeth and tongue to serve food, chews and mixes with saliva. It is very important to manage cleanliness after ingesting food.

When food is consumed, food waste remains between the teeth, which makes it a good environment for bacteria to reproduce. So, toothbrush is used to remove toothbrushes.

The toothbrush includes a handle and a toothbrush head having bristles, and is used to clean tooth and gums with toothpaste on the bristles.

In order to remove the effective pragmatism, it is important that the bristles touch the tooth and all areas of the tooth so that the toothbrush is evenly applied.

However, the conventional toothbrush has a problem that the area of the toothbrush head is fixed to a fixed size and the density of the bristles is fixed, which makes it difficult to effectively clean teeth having different sizes and narrow corners.
