Description

Interdental brush with stopper to maintain cleaning brush positioning ability and process thereof

Technical Field

The invention relates to a structure and a process of an interdental brush, in particular to an L-shaped interdental brush, wherein a cleaning rod of the cleaning brush is arranged in a grab handle in an L shape and is embedded and clamped by a stop block in the grab handle, so that the cleaning rod can be positioned in the grab handle really.

Background

Most people usually keep the oral cavity clean by brushing and gargling, and although the toothbrush has good plaque removing effect on the buccal surface, labial surface, lingual surface, occlusal surface and the like of the human body, the toothbrush cannot achieve complete cleaning effect on the gaps between adjacent teeth, so people usually adopt cleaning tools capable of penetrating through the gaps between the teeth (or referred to as tooth gaps and tooth gaps), such as: toothpick, dental floss and interdental brush …, etc., to effectively clean the gap between adjacent teeth and maintain personal hygiene.

However, the tooth root surface of the tooth is mostly concave-convex in the longitudinal section of the tooth, so that the linear structure of the toothpick and the dental floss cannot effectively clean the tooth root surface, on the contrary, the interdental brush is provided with a cleaning brush inserted into one end of the handle, the cleaning brush is provided with a plurality of soft plastic bristles, and the plastic bristles can be extruded and bent to be in direct contact with the tooth root surface, so as to effectively remove tartar and dental plaque on the tooth; therefore, the interdental brush has excellent cleaning effect, and is gradually popularized in the general public, so that the related industry has no effort to improve the structure of the existing interdental brush.

Generally speaking, in the production process of the existing interdental brush structure, a practitioner usually inserts only one end of the cleaning brush into one end of the handle in a straight line, that is, no additional positioning design is provided between the cleaning brush and the handle, therefore, the inventor found that the interdental brush structure of the aforesaid design easily causes the problem of insufficient tightness between the cleaning brush and the handle, after all, the gap and position between each person and each tooth are slightly different, when the user cleans the oral cavity by brushing the interdental space, the cleaning brush and the teeth are inevitably rubbed constantly, especially when cleaning the teeth in the deep oral cavity, the user must constantly adjust the holding angle of the hand to clean thoroughly, at this time, the cleaning brush is easily inserted into the smaller gap and held by the adjacent teeth, and then, after the user pulls the interdental brush vigorously, the position of the cleaning brush contacting the handle is easy to loosen, and the cleaning brush falls off from the handle, so that the cleaning action is interrupted, and the tongue or the oral cavity may be scratched by the cleaning brush left in the oral cavity of the user.

Therefore, how to design a new interdental brush structure and the process thereof to provide people with better experience and favor them is an important issue to be solved.
