Powered brush

Abstract

A powered brush is provided comprising a plurality of automated bristles that are driven in order to facilitate application of shave cream to a user's face while raising hairs off the face and stimulating, exfoliating, lubricating and moisturizing the skin. The powered brush comprises a handle having a top end, a bottom end and a longitudinal axis therebetween. A brush head comprises a plurality of bristles projecting away from the top end in a longitudinal direction is attached to a brush cup which is disposed at the top end of the handle and is movable relative thereto. An internal mechanism couples a motor drive shaft to the brush cup. The internal mechanism translates rotational movement of the motor drive shaft to reciprocating motion of the brush cup causing the brush cup and corresponding brush head attached thereto to oscillate linearly in the longitudinal direction.

         4 . The powered brush of  claim 1  wherein the plurality of bristles is selected from the group badger hair, boar hair, horse hair. 
     
     
         5 . The powered brush of  claim 1  wherein the plurality of bristles comprises synthetic bristles. 
     
     
         6 . The powered brush of  claim 5  wherein the synthetic bristles comprises nylon. 
     
     
         7 . The powered brush of  claim 1  wherein brush cup oscillates linearly at a frequency ranging from about 100 Hertz to about 800 Hertz. 
     
     
         8 . The powered brush of  claim 1  wherein brush cup oscillates linearly at a frequency ranging from about 200 Hertz to about 400 Hertz. 
     
     
         9 . The powered brush of  claim 1  wherein brush cup oscillates linearly, in and out a distance ranging from about 1.0 mm to about 2.0 mm. 
     
     
         10 . The powered brush of  claim 1  wherein brush cup oscillates linearly, in and out a distance of 1.5 mm. 
     
     
         11 . The powered brush of  claim 1  further comprising a battery compartment adjacent to the motor and a battery cap removably attached to the bottom end of the handle providing access to the battery compartment. 
     
     
         12 . The powered brush of  claim 11  wherein the battery cap is removably attached to the handle via screw threads. 
     
     
         13 . The powered brush of  claim 1  wherein the internal mechanism comprises:
 a. a first gear attached to the motor drive shaft; 
 b. a second gear meshed with the first gear; 
 c. an elongated cam feature attached to the second gear, the elongated cam feature including an outer surface; and 
 d. a cam follower link connected to the brush cup, the cam follower link including a cam slot wherein the elongated cam feature engages the cam slot allowing complete rotation of the elongated cam feature as the outer surface contacts the cam slot; 
 wherein as the first gear drives the second gear, the elongated cam feature rotates driving the cam follower link in a linear, up and down motion. 
 
     
     
         14 . The powered brush of  claim 13  wherein the second gear and first gear include a gear ratio wherein the gear ratio is 2.25. 
     
     
         15 . The powered brush of  claim 13  wherein the first gear comprises a pinion and the second gear comprises a crown gear. 
     
     
         16 . The powered brush of  claim 13  wherein the first gear and the second gear comprise bevel gears. 
     
     
         17 . The powered brush of  claim 13  wherein the motor and the drive mechanism are linearly aligned along the longitudinal axis. 
     
     
         18 . The powered brush of  claim 11  where in the handle and battery cap are chrome plated metal. 
     
     
         19 . The powered brush of  claim 1  including a housing mounted inside of the handle wherein the housing accommodates the motor, drive mechanism, and battery compartment. 
     
     
         20 . The powered brush of  claim 1  wherein the handle further comprises a power button in the handle between the top end and the bottom end wherein the power button includes an LED which lights when the power button is depressed and the powered brush is activated.
