Device to treat hair using ultrasound

Abstract

With a device ( 1 ) to treat hair using ultrasound having two clamps ( 2, 3 ), which are connected to one another via a joint ( 4 ) and which swivel, an oscillating body ( 5 ) is arranged on an interior side ( 6 ) of a clamp ( 3 ). The oscillating body ( 5 ) is positioned such that a strand of hair ( 7 ), which is clamped between the clamps ( 2, 3 ) when the clamps are closed, comes into contact with the oscillating body ( 5 ) or is touching it. An ultrasound generator ( 8 ) and a resonator ( 9 ) are connected to one another and generate an ultrasound frequency for the oscillating body ( 5 ). So that not only the ultrasound vibration is transmitted to the strand of hair ( 7 ) and that a product ( 27 ) is better distributed in the hair, but that also a quicker reaction of the product occurs on the hair, it is suggested to additionally design the oscillating body ( 5 ) as a heat generator. This is achieved in that the direction of oscillation ( 11 ) of the oscillating body ( 5 ) is the same as the direction ( 12 ) in which the clamp ( 3 ) having the oscillating body ( 5 ) extends.
