Interdental brush with a stopper to maintain the positioning ability of the cleaning brush and its manufacturing process

The invention relates to the structure and process of the interdental brush, in particular to an L-shaped interdental brush, and the cleaning rod of the cleaning brush is placed in the L shape in the handle and is blocked by the handle. The block is snapped in place so that the cleaning rod can be securely positioned in the handle.

Most people usually keep their mouth clean by brushing their teeth and gargle. Although the "toothbrush" has good plaque removal effect on the buccal, lip, lingual and occlusal surfaces of the human body, In the gap between adjacent teeth, the "toothbrush" can not achieve the effect of complete cleaning. Therefore, people usually use cleaning tools such as toothpicks and dental floss that can pass through the interdental space (or teeth and teeth). Products such as interdental brush, etc., to effectively clean the gap between adjacent teeth and maintain personal hygiene.

However, in the longitudinal section of the tooth, the surface of the root is mostly concave and convex. Therefore, the linear structure of the toothpick and the floss cannot effectively clean the surface of the root. Otherwise, the interdental brush is inserted at one end of the handle. Brush, the cleaning brush is provided with a plurality of fine soft plastic bristles, and the plastic bristles can be bent and bent straight to fit the surface of the root, effectively removing tartar and plaque on the teeth, in addition, the human mouth At the back of the last tooth, the general toothpick and toothbrush are not cleaned. Therefore, the grip of the interdental brush will be designed in an L shape, so that the user can easily extend the cleaning brush into the teeth of the rear teeth. In the seam; it is known that the interdental brush has an excellent cleaning effect. Gradually popularizing it in the general public, this move has also made it difficult for relevant operators to improve the structure of the existing "interdental brush".

In general, the structure of the existing interdental brush, in the production process, the industry usually only inserts one end of the cleaning brush linearly into one end of the handle, that is, between the cleaning brush and the handle, No additional positioning design has been added. Therefore, the inventors have found that the interdental brush structure of the aforementioned design is liable to cause a problem of insufficient tightness between the cleaning brush and the handle. After all, the spacing of the teeth of each person and each tooth is The position is slightly different. When the user cleans the mouth with the interdental brush, the cleaning brush and the teeth are bound to constantly rub, especially when cleaning the teeth deep in the mouth, the user must constantly adjust the hand grip. The angle can be thoroughly cleaned. At this time, the cleaning brush is easily embedded in the small tooth gap and is held by the adjacent teeth. When the user pulls the interdental brush vigorously, it is easy to cause The position where the cleaning brush is in contact with the grip is loose, which causes the cleaning brush to fall off from the grip, which not only interrupts the cleaning action, but also the cleaning brush left in the user's mouth may also scratch the tongue or mouth. The circumstances.

Therefore, how to design a new "interdental brush" structure and its process, in order to provide people with a better experience of use, and then get people's favor, is the important problem that the present invention is intended to solve here.

In view of the existing interdental brush, it is easy to cause the user to loosen the handle of the cleaning rod during the cleaning process due to insufficient positioning ability of the cleaning rod, thereby ruining the user's experience.
