Description

Toothbrush with folded toothbrush head

The present invention relates to a foldable toothbrush, and more particularly, to a toothbrush head foldable toothbrush capable of adjusting the angle of a portion of the toothbrush head.

The oral cavity is the starting point of the digestive system, and it uses the teeth and tongue to hold food, chew it well, and mix it with saliva.

When food is ingested, food debris is left between the teeth, creating a good environment for bacteria to grow.

The toothbrush has a structure consisting of a toothbrush head having a handle and bristles implanted, and is used to clean teeth and gums by applying toothpaste on the bristles.

However, the conventional toothbrush is formed in a flat shape in which the handle and the toothbrush head are in a straight line, so that when you want to clean the inner part of the molars, you have to brush the toothbrush by bringing the toothbrush head closer to your mouth.

In order to solve the above problems, in the prior art, a plurality of dental hair pieces having hairs implanted at the tip of the toothbrush rest are inserted into a leaf spring in a curved state, and the button can be moved along the bristles and the guide hole of the toothbrush head. When the button is raised and lowered by connecting the button to the connecting bar to be integrated, the angle adjustment of the tip of the toothbrush bristles is adjusted to the inside, so that the inner part of the molars can be cleaned effectively.

However, in the prior art, since the dental crown for angle adjustment is formed small at the tip of the toothbrush head, it does not reach to the back of the molars, thereby incompletely cleaning the teeth. When brushing between the teeth and gums, the use of a toothbrush was unnatural and the cleaning effect was poor.

In addition, the prior art has a problem in that it is formed in a curved spring structure and is not fixed, so that the bristles are shaken, which makes it difficult to brush. There was a problem of poor portability to be provided separately.

In addition, there is a problem in that the production efficiency is decreased and the cost is increased because the structure is complicated in a structure in which a plurality of chimo pieces are inserted into the leaf spring.

On the other hand, since the general toothbrush has a flat head with bristles, it is difficult to cleanly clean the inside of the molars or the shape of the teeth while brushing teeth.

Accordingly, the present invention has been devised to solve the above problems, and the problem to be solved is that the head portion of the bristles is configured to be divided, and it is possible to adjust the angle between the divided head portions, and the angle adjustment is possible. It is to provide a toothbrush head foldable toothbrush having a function of fixing it so as not to unfold while brushing in this state.

However, the technical problems to be achieved in the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned are clearly to those of ordinary skill in the art to which the present invention belongs from the description below. can be understood

The present invention has been created to improve the problems of the prior art as described above, as a toothbrush capable of brushing teeth while adjusting the angle of the bristles, the toothbrush body comprising a handle and a head provided with bristles; a first head portion formed at the distal end of the toothbrush body and provided with bristles and the angle is adjusted; a second head portion having one end connected to the first head portion and the other end connected to the handle portion and provided with bristles; a segment part connected between the first head part and the second head part to allow rotation of the first head part; and an angle adjusting member provided in each of the first head part and the second head part to adjust the inclination angle of the first head part.

In addition, the segmented part may allow rotation of the first head part by coupling the first head part and the second head part by hinges, respectively, at both outer sides of the first head part and the second head part.

In addition, the angle adjusting member may include a spring provided inside the first head part; an angle adjuster connected to the spring and provided with an elastic force and having a key handle protruding to the outside; And it is provided in the second head portion and fixed teeth for fixing the angle adjuster; may include.

According to an embodiment of the present invention, the head portion of the bristles is divided into a first head portion and a second head portion, and a segmented portion is provided to enable angle adjustment between each divided head portion. With the angle adjusted through the segmented part, the angle adjuster is fixed to the fixed teeth so that it does not straighten while brushing.

That is, the divided first and second heads are connected in a flat manner in normal times, and when brushing teeth, you can do it as usual, and when cleaning the inside of the molars, the first and second heads are used through the angle adjustment member. By adjusting the angle of the part, the bristles reach the inside effectively, and even when cleaning curved parts according to the shape of the teeth, the cleaning power of the teeth can be strengthened compared to the conventional toothbrush.

However, the effects obtainable in the present invention are not limited to the above-mentioned effects, and other effects not mentioned will be clearly understood by those of ordinary skill in the art to which the present invention belongs from the following description. will be able
