Electric Makeup Brush

Abstract

An object of the present invention is to provide an electrically-operated makeup tool to enable, through electric operation, a motion different from makeup work performed by hand, an excellent finish of makeup relative to when performed by hand, and a comfortable feeling upon contact with the skin that has not been conventionally achievable, in addition to enabling application of powdered cosmetic material in a short period of time without dirtying the hand. Provided is a makeup brush that causes an applicator formed of bundled bristles to reciprocally vibrate in a direction in which the bristles are oriented with an electric drive unit such that the applicator dabs cosmetic material onto the skin with the tip of the bristles, wherein the amplitude of the reciprocal vibration is 2 to 10 mm, the vibration frequency of the reciprocal vibration is 3 to 50 Hz, and the length of the bristles is 15 to 30 mm.

1 . An electric makeup brush that causes an applicator formed of bundled bristles to reciprocally vibrate in a direction in which the bristles are oriented with an electric drive unit such that the applicator dabs cosmetic material onto a skin with the tip of the bristles. 
     
     
         2 . The electric makeup brush according to  claim 1 , wherein the drive unit includes an electric motor, a speed reduction mechanism for reducing rotation of the electric motor, and a reciprocating motion conversion mechanism that converts rotation reduced by the speed reduction mechanism into reciprocating motion. 
     
     
         3 . The electric makeup brush according to  claim 2 , wherein the reciprocating motion conversion mechanism includes a cam mechanism that converts rotation reduced by the speed reduction mechanism into reciprocating motion in a direction identical or orthogonal to a rotating shaft. 
     
     
         4 . The electric makeup brush according to  claim 3 , wherein the cam mechanism includes a push spring for biasing an arm to cause contact with a cam. 
     
     
         5 . The electric makeup brush according to  claim 2 , wherein the reciprocating motion conversion mechanism includes a crank mechanism that converts rotation reduced by the speed reduction mechanism into reciprocating motion in a direction orthogonal to a rotating shaft. 
     
     
         6 . The electric makeup brush according to  claim 1 , wherein an amplitude of the reciprocal vibration is 2 to 10 mm. 
     
     
         7 . The electric makeup brush according to  claim 1 , wherein a vibration frequency of the reciprocal vibration is 3 to 50 Hz. 
     
     
         8 . The electric makeup brush according to  claim 1 , wherein a length of each of the bristles is 15 to 30 mm. 
     
     
         9 . The electric makeup brush according to  claim 1 , wherein an outer diameter of the applicator is 10 to 35 mm. 
     
     
         10 . The electric makeup brush according to  claim 1 , wherein a tip surface of the applicator has a flat shape. 
     
     
         11 . The electric makeup brush according to  claim 1 , wherein a tip surface of the applicator has a flat shape inclined with respect to the direction in which the bristles are oriented. 
     
     
         12 . A makeup method, comprising using the electric makeup brush according to  claim 1  to dab cosmetic material onto a skin with the tip of the bristles. 
     
     
         13 . The electric makeup brush according to  claim 2 , wherein an amplitude of the reciprocal vibration is 2 to 10 mm. 
     
     
         14 . The electric makeup brush according to  claim 3 , wherein an amplitude of the reciprocal vibration is 2 to 10 mm. 
     
     
         15 . The electric makeup brush according to  claim 2 , wherein a vibration frequency of the reciprocal vibration is 3 to 50 Hz. 
     
     
         16 . The electric makeup brush according to  claim 3 , wherein a vibration frequency of the reciprocal vibration is 3 to 50 Hz. 
     
     
         17 . The electric makeup brush according to  claim 2 , wherein a length of each of the bristles is 15 to 30 mm. 
     
     
         18 . The electric makeup brush according to  claim 2 , wherein an outer diameter of the applicator is 10 to 35 mm. 
     
     
         19 . The electric makeup brush according to  claim 2 , wherein a tip surface of the applicator has a flat shape. 
     
     
         20 . The electric makeup brush according to  claim 2 , wherein a tip surface of the applicator has a flat shape inclined with respect to the direction in which the bristles are oriented.
