Hair-dressing device

Abstract

The invention relates to a hair-dressing device comprising a motor-driven rotary part ( 8 ) slaved to an angular accelerometer ( 1 ) arranged in said handle ( 7 ), said accelerometer ( 1 ) detecting, during use, the rotary pulses generated around the longitudinal shaft of said handle ( 7 ) and transmitting a signal for starting up the motor in the desired direction.

1 . A hair styling device comprising a rotary part motor controlled by an angular accelerometer in a handle, said accelerometer detecting, in use, rotational impulses about the longitudinal axis of said handle ( 7 ) imparted by a user and transmitting a motor start-up signal in the desired direction. 
     
     
         2 . A hair styling device according to  claim 1  including a switch on said handle for activating and deactivating said accelerometer. 
     
     
         3 . A hair styling device according to  claim 1  wherein said accelerometer comprises:
 a flywheel freely articulated on an axis of rotation; 
 a transmitter and a torque sensor connected to an electronic circuit comprising a microcontroller for detecting, in use, the angle of rotation of the flywheel relative to said sensors; counting said microcontroller, in use, the signals between the transmitter and sensors and detecting the direction of rotation during a pulse given by the user on the handle in a desired direction of rotation and transmitting an engine start signal in the desired direction if the angle of rotation generated by the pulse is greater than a preset angle. 
 
     
     
         4 . A hair styling device according to  claim 1  wherein said motor is located in the rotatable part of said hair device. 
     
     
         5 . A hair styling device according to  claim 1  wherein said hairdressing device is a rotary brush or a hair curler. 
     
     
         6 . A hair styling apparatus, which comprises:
 a handle defining a longitudinal axis;   a rotating element connected to the handle and adapted for rotational movement about the longitudinal axis;   a motor for driving the rotating element   an accelerometer disposed in the handle, the accelerometer responsive to at least one rotational impulse imparted by a user about the longitudinal axis of the handle to send a signal to actuate the motor in the selected direction.   
     
     
         7 . The hair styling apparatus according to  claim 6  including a switch on the handle for activating and deactivating the accelerometer. 
     
     
         8 . The hair styling apparatus according to  claim 6  wherein the rotating element is a hair brush. 
     
     
         9 . The hair styling apparatus according to  claim 8  wherein the hair brush includes a fan. 
     
     
         10 . The hair styling apparatus according to  claim 6  wherein the rotating element is a hair curler.
