Ultrasonic hair treatment device

Abstract

An ultrasonic hair treatment device is provided to apply ultrasonic vibrations to a user's hair for enhancing the penetration of a hair treatment composition into the hair. An ultrasonic vibration element is held on a support to which a clamp member is pivotally connected, so as to give the ultrasonic vibration to the hair clamped between the support and the clamp member. The ultrasonic vibration element is configured to have a rectangular vibration face and to have a plurality of resonant points arranged in a lattice pattern on the rectangular vibration face. Thus, the ultrasonic vibrations of maximum amplitude developed at the plural resonance points can be applied to the hair over the entire rectangular vibration face, thereby applying the uniform ultrasonic vibration effect to the hairs for expediting the penetration of a hair treatment composition into the hairs.

1 . An ultrasonic hair treatment device comprising: 
 a support configured to carry an ultrasonic vibration element;    a clamp member configured to clamp hairs between the clamp member and the support for applying ultrasonic vibrations from said ultrasonic vibration element to the hairs;    wherein said ultrasonic vibration element is configured to have a rectangular vibration face and to have a plurality of resonant points arranged in a lattice pattern on said rectangular vibration face.    
   
   
       2 . The device as set forth in  claim 1 , wherein 
 said ultrasonic vibration element is configured to come into direct contact with the hairs clamped between said clamp member and said support.    
   
   
       3 . The ultrasonic hair treatment device as set forth in  claim 1 , wherein 
 said support is elongated to have a longitudinal axis and is pivotally connected at one longitudinal end to said clamp member,    said ultrasonic vibration element is mounted on said support to have its lengthwise axis inclined relative to said longitudinal axis of said support.    
   
   
       4 . The ultrasonic hair treatment device as set forth in  claim 1 , wherein 
 said support is elongated to have a longitudinal axis and is configured to carry at least one said ultrasonic vibration element;    said clamp member is configured to carry at least one auxiliary vibration element, said ultrasonic vibration element and said auxiliary vibration element are arranged along a direction crossing with said longitudinal axis.    
   
   
       5 . The ultrasonic hair treatment device as set forth in  claim 4 , wherein 
 a controller is provided to oscillate said ultrasonic vibration element and said auxiliary ultrasonic vibration element alternately with each other.    
   
   
       6 . The ultrasonic hair treatment device as set forth in  claim 1 , wherein 
 one of said support and said clamp member is configured to have bumps spaced in a lengthwise direction, while the other of said support and said claim member is configured to have recesses which fit with said bumps respectively when said clamp member is closed on said support.    
   
   
       7 . The ultrasonic hair treatment device as set forth in  claim 1 , wherein 
 a plurality of said ultrasonic vibration elements are stacked with each other on said support.
