Description

Be the gradually curved arch bristle face toothbrush of sharp projection of central authorities

The utility model relates to toothbrush, refers to be the gradually curved arch bristle face toothbrush of sharp projection of central authorities especially.

Existing toothbrush such as Fig. 1-3, an one toothbrush lever 1 and a bristle portion 2, the high-quality green tea 210 of its each strand bristle 21 entirely trims on an imaginary basal plane F, the user scrubs when cleaning one's teeth in upper and lower, because isometric smooth bristle 21 is flat on the outside or the inboard of each tooth T, be difficult for making bristle 21 to be close between the two tooth halogen T, promptly be difficult for stretching in the teeth space T1, even firmly press to tooth T, also only several bristles 21 enter in the teeth space T1, the side that only terminates in each bristle 21 is scraped toothwash flank edge face T2, and effect is not satisfactory so this structure of existing toothbrush cleans one's teeth.

The purpose of this utility model is the above-mentioned shortcoming that overcomes existing toothbrush, provides a kind of effect that cleans one's teeth to be the gradually curved arch bristle face toothbrush of sharp projection of central authorities preferably.

The purpose of this utility model is achieved in that and is the gradually curved arch bristle face toothbrush of sharp projection of central authorities, it comprises a toothbrush lever and a bristle portion, this bristle portion is planted in the front end of toothbrush lever by the bristle arrangements embedding of multiply bunchy, it is characterized in that: this bristle portion from its vertical two ends and both lateral sides be upwards gradually sharp projection of curved arch ground towards central authorities, be and be the curved arch bristle face.

Above-mentioned design, the user scrubs when cleaning one's teeth in upper and lower, and this is most bristles of curved arch bristle face, is convenient to stretch between each teeth space, reaches the effect purpose preferably that cleans one's teeth, and can thoroughly remove swill and dirt between teeth space.

Below by drawings and Examples the utility model is described further again.
