Interdental brush

Abstract

The present invention discloses an interdental brush, the interdental brush of the present invention comprises a handle including a gripping portion, a brush coupling portion provided at a front end of the gripping portion and a bending portion provided on the gripping portion for allowing the brush coupling portion to be bent with respect to the gripping portion in the first direction and for restraining a bending of the brush coupling portion in the second direction which is opposite to the first direction; and a brush portion coupled to the brush coupling portion of the handle. Due to the above structure, the interdental brush of the present invention can clean conveniently and easily an interdental space between molar teeth as well as an interdental space between front teeth. In particular, the brush portion of the interdental brush can be inserted simply and accurately into an interdental space between molar teeth placed in a narrow space.

1 . An interdental brush, comprising;
 a handle including a gripping portion, a brush coupling portion provided at a front end of the gripping portion and a bending portion provided on the gripping portion for allowing the brush coupling portion to be bent with respect to the gripping portion in the first direction and for restraining a bending of the brush coupling portion in the second direction which is opposite to the first direction; and   a brush portion coupled to the brush coupling portion of the handle.   
   
   
       2 . The interdental brush according to  claim 1 , wherein the bending portion consists of a bending groove and a bending-restraining groove formed on both surfaces of a front end portion of the gripping portion, the bending groove and the bending-restraining groove are formed in the direction which is perpendicular to the longitudinal direction of the gripping portion, and both inner surfaces of the bending groove make a certain angle with each other and both inner surfaces of the bending-restraining groove are narrowly spaced from each other. 
   
   
       3 . The interdental brush according to  claim 1 , wherein the both inner surfaces of the bending groove make an acute angel with each other and both side surfaces of the bending-restraining groove are disposed parallel to each other. 
   
   
       4 . The interdental brush according to  claim 1 , wherein the gripping portion has a curved shape, the bending portion is formed on a first curved surface of the gripping portion to be corresponded to an interdental space of the user, and the bending-restraining groove is formed on a second curved surface being opposite to the first surface. 
   
   
       5 . The interdental brush according to  claim 1 , wherein the gripping portion has friction surfaces formed on both sides thereof. 
   
   
       6 . The interdental brush according to  claim 1 , wherein the brush portion has a core wire which is insert-injected into the brush coupling portion 
   
   
       7 . The interdental brush according to  claim 1 , wherein the brush portion is coupled detachably to the brush coupling portion.
