Electric Splint

Abstract

Disclosed is an electric splint, used for straightening hair and curling hair, which includes two splint parts clamped to each other and hinged to each other at one end, the splint part includes an elongated housing, a heating-plate component mounted on a clamped side of the housing, comb teeth located in a position corresponding to an axial position of the heating-plate component and distributed on an outer surface of the housing, and an air duct located inside the housing; air outlet holes communicating with the air duct are provided at two side edges of the housing corresponding to a distribution area of the comb teeth, and the electric splint further includes a fan component and an air inlet for providing cold air to the air duct.

What is claimed is: 
     
         1 . An electric splint, used for straightening hair and curling hair, comprising:
 two splint parts clamped to each other and hinged to each other at one end, wherein, the splint part comprises:
 an elongated housing; 
 a heating-plate component mounted on a clamped side of the housing; 
 comb teeth located in a position corresponding to an axial position of the heating-plate component and distributed on an outer surface of the housing; and 
 an air duct located inside the housing; 
 wherein, air outlet holes communicating with the air duct are provided at two side edges of the housing corresponding to a distribution area of the comb teeth, and the electric splint further comprises a fan component and an air inlet for providing cold air to the air duct. 
   
     
     
         2 . The electric splint of  claim 1 , wherein:
 a tail end is provided at a rear end of a hinged part of the two splint parts;   the fan component and the air inlet are arranged at the tail end; and   a front end of the tail end is in communication with the air ducts of the two splint parts.   
     
     
         3 . The electric splint of  claim 2 , wherein:
 the tail end is cylindrical,   a lower half of the tail end is integrally fixed with an end of one of the splint parts;   the tail end has a rotating part rotatable around an axis;   a limiting block and a limiting groove that can be axially slid into and matched with each other are provided between the rotating part and the end of the other movable splint part; and   when the rotating part is rotated to make the limiting block and the limiting groove mismatched, the movable splint part cannot be opened.   
     
     
         4 . The electric splint of  claim 2 , wherein:
 the tail end comprises a cylindrical outer shell;   the fan component comprises a motor and fan blades axially arranged in the outer shell; and   the air inlet comprises air inlet holes circumferentially arranged on the outer shell.   
     
     
         5 . The electric splint of  claim 1 , wherein:
 the comb teeth are arranged at a front section of the splint part;   a rear section of the splint part is a handle section;   the air duct axially passes through the splint part;   one of the splint parts is further provided with a control circuit board in the handle section; and   control buttons corresponding to the control circuit board are provided on the handle section.   
     
     
         6 . The electric splint of  claim 5 , wherein, a spring is arranged between the two splint parts at an end of the handle section, so that the two splint parts are in a normally open state. 
     
     
         7 . The electric splint of  claim 1 , wherein, the heating-plate component comprises a heat-conducting plate embedded and fixed on the housing, and a PTC heating body and an NTC temperature control element attached to the back of the heat-conducting plate. 
     
     
         8 . The electric splint of  claim 7 , wherein:
 the heat-conducting plate has a hollow cavity along its length;   and the PTC heating body and the NTC temperature control element are mounted in the hollow cavity.   
     
     
         9 . The electric splint of  claim 1 , wherein, the comb teeth have round heads at their top ends, and the comb teeth are staggered on a surface of the housing in a circumferential direction.
