Hair curling device

Abstract

A hair curling device has a hand grip, and a heating barrel extending from the hand grip to have a lengthwise axis. A hair clamp is held by the hand grip to be moveable between a hair lamping position and a release position. The hair clamp is curved in match with the curling surface in order to curl the hair clamped between the hair lamp and the barrel. The device includes at least one negative ion generator with an ion port for emitting negative ions. The negative ion generator gives a cone emission axis along which the negative ions are emitted out through the ion port in an emission cone. The ion port is located at a portion offset axially from the barrel as well as offset circumferentially from the hair clamp with the cone emission axis being oriented in such a direction that the emission cone extends mainly along the axial of the barrel to cover a region outwardly of the curling surface of the barrel, i.e., the hair clamp. Thus, the negative ion generator can emit the negative ions in a concentrated manner to the hair just out of the hair clamp for adding the negative ion treatment effect to the curled hair.

1 . A hair curling device comprising: 
 a hand grip;    a heating barrel extending from said hand grip to have a lengthwise axis; said heating barrel being configured to wind user's hair therearound and to have a rounded curling surface on a part of its circumference;    a hair clamp held by said hand grip to be movable between a clamping position of clamping the hair on said curling surface and a release position of releasing the hair from the curling surface, said hair clamp being curved in match with said curling surface in order to curl the hair clamped between the hair clamp and the barrel;    characterized in that    said device includes at least one negative ion generator with an ion port for emitting negative ions therefrom, said negative ion generator configured to have a cone emission axis along which said negative ions are emitted out through said ion port in an emission cone;    said ion port is located at a portion offset axially from said barrel as well as offset circumferentially from said hair clamp with said cone emission axis being oriented in such a direction that said emission cone extends mainly along said axis of the barrel to cover a region outwardly of said curling surface.    
   
   
       2 . The hair curling device as set forth in  claim 1 , wherein 
 said negative ion generator are mounted on said hand grip adjacent to said barrel with said cone emission axis oriented radially outwardly of said barrel at an inclination angle (θ) of less than 45° with respect to the axis of said barrel within a horizontal plane which is perpendicular to a vertical plane passing through a width center and said axis of the barrel.    
   
   
       3 . The hair curling device as set forth in  claim 2 , wherein 
 two said negative ion generator is mounted around said hand grip in a generally diametrically opposite relation from each other.    
   
   
       4 . The hair curling device as set forth in  claim 2 , wherein 
 said ion port is spaced radially outwardly from the circumference of said barrel.    
   
   
       5 . The hair curling device as set forth in  claim 1 , wherein 
 said heating barrel is provided with an end cap at its axial end opposite to said hand grip,    said negative ion generator being mounted on said end cap.    
   
   
       6 . The hair curling device as set forth in  claim 1 , wherein 
 said heating barrel comprises a first barrel half and a second barrel half each shaped to have a semi-circular cross section with a top rounded outer surface and a flat straightening surface, the top rounded surface of said first barrel half giving said curling surface,    said hand grip comprises a first grip half and a second grip half which support said first barrel half and said second half barrel, respectively, said first and second grip halves being pivotally connected to each other so as to move the first barrel half between a closed position of keeping the respective flat straightening surfaces in a closely adjacent relation for straightening the hairs entrapped therebetween and an open position of releasing the hair,    said first grip half carrying said hair clamp as well as said negative ion generator,    said negative ion generator being arranged such that said emission cone is intersected by a mating plane defined between the straightening surfaces in the closed position of said barrel so as to cover a region immediately outwardly of    said straightening surfaces.    
   
   
       7 . The hair curling device as set forth in  claim 6 , wherein 
 said negative ion generator is mounted on said hand grip adjacent to said barrel with said cone emission axis oriented radially outwardly of said barrel at an inclination angle (θ) of less than 45° with respect to the axis of said barrel within a horizontal plane which is perpendicular to a vertical plane passing through a width center and said axis of the barrel,    said cone emission axis also inclined at an inclination angle (ω) of less than 30° with respect to the axis of said barrel within said vertical plane.    
   
   
       8 . The hair curling device as set forth in  claim 6 , wherein 
 two said negative ion generators are mounted on opposite sides of said first grip half.    
   
   
       9 . The hair curling device as set forth in  claim 6 , wherein 
 said second grip half carries like negative ion generator which gives an emission cone covering said region in an overlapping relation with said emission cone given by said negative ion generator on said first grip half.
