Brush body and toothbrush

Abstract

A brush body and toothbrush that allows for current to easily flow from conductive bristles to oral tissues or enhance ionization of electrolytic medicinal components. The brush body includes a mixed bristle bundle arranged on an anchoring surface and including a plurality of conductive bristles and a plurality of insulative bristles. A reference plane is set on the anchoring surface. The conductive bristles have a height from the reference plane, and the insulative bristles have a height from the reference plane that differs from the height of the conductive bristles.

1 . A brush body including an anchoring surface, the brush body comprising a mixed bristle bundle arranged on the anchoring surface, wherein
 the mixed bristle bundle includes a plurality of conductive bristles and a plurality of insulative bristles,   a reference plane is set on the anchoring surface,   the conductive bristles have a height from the reference plane, and   the insulative bristles have a height from the reference plane that differs from the height of the conductive bristles.   
     
     
         2 . The brush body according to  claim 1 , wherein each of the conductive bristles includes a conductive core, which has a tip, and a coating, which covers the core excluding at least the tip. 
     
     
         3 . The brush body according to  claim 1 , wherein the height of the insulative bristles from the reference plane is less than the height of the conductive bristles from the reference plane, and the insulative bristles each include a tip at which a pit is formed to receive toothpaste. 
     
     
         4 . The brush body according to  claim 1 , wherein the height of the conductive bristles from the reference plane is less than the height of the insulative bristles from the reference plane, and the conductive bristles each include a tip at which a pit is formed to receive toothpaste. 
     
     
         5 . A toothbrush comprising the brush body according to  claim 1 . 
     
     
         6 . A brush body including an anchoring surface, the brush body comprising:
 a conductive bristle bundle arranged on the anchoring surface and including a plurality of conductive bristles; and   an insulative bristle bundle arranged on the anchoring surface and including a plurality of insulative bristles;   wherein a reference plane is set on the anchoring surface, the conductive bristle bundle has a height from the reference plane, and the insulative bristle bundle has a height from the reference plane that differs from the height of the conductive bristle bundle.   
     
     
         7 . The brush body according to  claim 6 , wherein the conductive bristles each include a conductive core, which has a tip, and a coating, which covers the core excluding at least the tip. 
     
     
         8 . The brush body according to  claim 6 , wherein the height of the insulative bristle bundle from the reference plane is less than the height of the conductive bristle bundle from the reference plane, and the insulative bristles of the insulative bristle bundle each include a tip at which a pit is formed to receive toothpaste. 
     
     
         9 . The brush body according to  claim 6 , wherein the height of the conductive bristle bundle from the reference plane is less than the height of the insulative bristle bundle from the reference plane, and the conductive bristles of the conductive bristle bundle each include a tip at which a pit is formed to receive toothpaste. 
     
     
         10 . A toothbrush comprising the brush body according to  claim 6 . 
     
     
         11 . A brush body including an anchoring surface, the brush body comprising:
 a plurality of mixed bristle bundles arranged on the anchoring surface and including a first mixed bristle bundle and a second mixed bristle bundle, wherein the mixed bristle bundles each include plurality of conductive bristles and a plurality of insulative bristles; and   wherein a reference plane is set on the anchoring surface;   in each mixed bristle bundle, the conductive bristles have a height from the reference plane, and the insulative bristles have a height from the reference plane that differs from the height of the conductive bristles; and   the first mixed bristle bundle has a height from the reference plane, and the second mixed bristle bundle has a height from the reference plane that differs from the height of the first mixed bristle bundle.   
     
     
         12 . The brush body according to  claim 11 , wherein the conductive bristles each include a conductive core, which has a tip, and a coating, which covers the core excluding at least the tip of the core. 
     
     
         13 . The brush body according to  claim 11 , wherein the height of the insulative bristles from the reference plane is less than the height of the conductive bristles from the reference plane, and the insulative bristles each include a tip at which a pit is formed to receive toothpaste. 
     
     
         14 . The brush body according to  claim 11 , wherein the height of the conductive bristles from the reference plane is less than the height of the insulative bristles from the reference plane, and the conductive bristles each include a tip at which a pit is formed to receive toothpaste. 
     
     
         15 . A toothbrush comprising the brush body according to  claim 11 .
