Description

Bar type hygiene toothbrush

The present invention relates to a bar-shaped sanitary toothbrush. More specifically, the present invention provides a toothbrush head 10 having a plurality of through holes 11 formed therein; And a bristle 20 formed of a focusing hair 21 formed of a top portion 21a serving as bristles and a lower portion 21b inserted into the through hole 11 of the toothbrush head 10. It is about a bar-shaped sanitary toothbrush.

Many changes and developments have been made since the toothbrush was invented, but the hygiene side due to the structural problems of the toothbrush has been overlooked due to the emphasis on convenience and cleaning of the tooth.

When checking the current state of toothbrush hygiene, which is currently used, the toothbrush, which looks relatively clean in appearance, is actually detected with a greater number of pathogenic bacteria having a higher sanitary index than a toilet bowl. This is an inevitable result of the structural defect between the base plate and the focusing head of the toothbrush head.

Where bacteria are cultured in a conventional toothbrush and the most bacteria are detected, the follicles are planted on the toothbrush bed plate and contact with each other. Looking at its detailed structure, the bristle itself is planted by concentrating about 110 to 120 fine bristles in each of about 16 to 20 holes on the upper surface of the toothbrush head.

Therefore, a fine gap is generated in the hole where the high-density focusing hair is transplanted by the movement of the focusing hair during brushing, and microorganisms and microorganisms in the oral cavity are pinched together with moisture due to the minute gap. In addition, the end of the high-density focusing hair in contact with the base plate is fixed to the base plate of a hard material, and foreign matters such as food waste are easily caught.

When brushing the toothbrush after brushing, the upper part of the focusing hair is easily rinsed out by the elasticity of the material's elasticity, so it is easy to clean it, but the end of the focusing hair fixed on the hard material has a limitation in the opening. The use of toothbrushes not only causes foreign substances to be caught, but especially the lower part of the central focusing head of the upper surface of the toothbrush head, so that foreign substances such as food scraps are not always properly cleaned and moist with moisture. As a result, many microorganisms exist in the bristles, which are shocking even beyond neglect of care, but many people are still using toothbrushes unsanitarily without knowing the facts.

Recently, toothbrushes have been recognized for their unhygienic condition. Toothbrushes including substances that increase antimicrobial activity in toothbrushes and toothbrush sterilizers for sterilizing bacteria are commercially available. However, the products are expensive and the bacteria can be sterilized to some extent. Tough food dregs, which are caught between the ends of the bundle, are still aesthetically filthy and odorous.

Accordingly, the present inventors can solve the structural problems of the existing toothbrushes that had to be cultured in the bristles bristles to minimize the entanglement of foreign matters such as food debris in the bristles, as well as to easily clean the toothbrush after brushing teeth The invention has led to the invention of a sanitary toothbrush which can be removed.

In addition, the present inventors have come to invent a sanitary toothbrush that not only facilitates the removal of moisture in the toothbrush by integrating the mother plate and the bristles, but also fundamentally blocks the environment in which bacteria are cultivated by remaining foreign matter and moisture in the minute gaps of the holes. .

It is an object of the present invention to improve the structural environment in which bacteria were cultivated in the bristles, thereby minimizing foreign substances such as food debris in the bristle bundles by separating the high density focusing hair and the bottom surface by a certain distance, and then brushing the toothbrush after brushing the teeth. It is to provide a sanitary toothbrush that can be easily removed when cleaning.

Another object of the present invention is to provide a sanitary toothbrush that can easily remove the moisture in the toothbrush by forming the base plate and the bristles as one body, as well as to block the environment in which bacteria and foreign matter remains in the fine gap of the hole. will be.

The present invention for achieving the above object, the toothbrush head 10 is formed with a plurality of through holes 11; And a bristle 20 having a focusing hair 21 formed of an upper end portion 21a serving as bristles and a lower end portion 21b inserted into the through hole 11 of the toothbrush head 10. The bar-shaped sanitary toothbrush is a technical point.

Here, the lower end portion 21b of the focusing hair is preferably inserted into the long 22 to be heated and compressed to be formed into a rod shape. In this case, the long 22 is made of the same material as the focusing hair 21. It is preferable that the focusing hair 21 is made of a material capable of maintaining the elasticity.

In addition, the lower end portion 21b of the focusing hair is preferably bonded to each other and formed into a rod shape, and in this case, the lower end portion 21b of the focusing hair is joined by the melting material 23 for bonding, which is filled in the bristle working mold 50. It is preferable to be bonded, and the fusion material 23 for bonding is preferably made of the same material as the focusing hair 21 or a material capable of maintaining the elasticity of the focusing hair 21.

In addition, the length of the lower end portion 21b of the focusing hair may be differently formed according to the insertion position of the toothbrush head 10 of the bristle 20, and may be inserted into the inner through hole 11a of the toothbrush head 10. It is preferable that the length of the focusing hair lower end 21b of the inner bristle 20a is longer than the length of the focusing hair lower end 21b of the outer bristle 20b inserted into the outer through-hole 11b of the toothbrush head 10.

In addition, it is preferable that the plastic elastic material 30 is fused and coated on the toothbrush head 10 top plate so that the toothbrush head 10 and the bristle 20 are integrally formed, and the toothbrush head 10 top plate It is preferable that the coverable space 12 in which the plastic elastic material 30 is fused and coated is formed.

In addition, the bristle 20 is inserted into the through-hole 11 so that a portion of the lower end of the focusing hair 21b protrudes from the bottom surface of the toothbrush head 10, and at this time, the toothbrush head 10 After the portion protruding from the bottom of the) is fused and fixed to the bottom of the head portion, it is preferable that the lower plate of the toothbrush head 10 is finished with a soft finishing material 40, the finishing material on the lower plate of the toothbrush head 10 It is preferable that a finishable space 13 for finishing with 40 is formed.

In addition, the shape of the bristle 20 is preferably any one selected from a circular column, rectangular column or elliptical column.

Unlike the conventional toothbrush in which the bristle hair is implanted directly into the mother hole, the bristle type hygiene toothbrush of the present invention is inserted into the lower end of the bristle hair by heating, compressing or using a melt, and the lower end of the bristle hair. After molding into a rod shape through a method of joining, etc., the hole is drilled into the head part, so that the high density focusing hair and the bottom surface are separated by a certain distance. As well as preventing foreign substances from being caught, there is an effect of facilitating the cleaning of the remaining foreign matter in the focusing hair when cleaning the toothbrush after brushing.

In addition, the bristle type hygiene toothbrush of the present invention distinguishes the inside and the outside in molding the hair, and the inner side of the head of the head portion of the head at the bottom of the converging hair rather than the outer side of the head is inferior in washing power due to poor finger contact. The longer length can maximize the cleaning power and minimize the phenomenon that food wastes can be entangled with each other by the effect of different lengths of bristles in the structure of clusters of clusters that are densely planted in a narrow head area.

Particularly, the small gap created after the insertion of the hairs in the bed hole is fused and coated with a plastic elastic material so that the mother board and the hairs are formed together to block the environment where bacteria are cultivated by remaining the foreign matter and water between the minute gaps. Hygienic use and care is possible.

As described above, when the present invention is applied to a real toothbrush, not only does it fundamentally block the environment in which pathogenic bacteria are cultivated in the hole gaps and clusters of the toothbrush, but also foreign substances, which are not easily removed, such as heavy food waste, are easy to clean and hygienic use of the toothbrush. And management is possible.
