Electric hair curler

Abstract

The present disclosure provides an electric hair curler. The electric hair curler includes a handle shell and a hair curling tube. A first electric connector is arranged in the handle shell. The hair curling tube is rotatably connected to the handle shell. A heating assembly and a second electric connector are arranged in the hair curling tube. The heating assembly and the second electric connector rotate synchronously with the hair curling tube. The heating assembly is electrically connected to the second electric connector. When the hair curling tube rotates relative to the handle shell, the second electric connector rotates relative to the first electric connector, and the second electric connector is electrically connected to the first electric connector to turn on a circuit where the heating assembly is located.

         2 . The electric hair curler according to  claim 1 , wherein the first electric connector is provided with a circular-ring-shaped conductive sheet; the second electric connector is provided with a conductive spring needle; the conductive spring needle is pressed against the conductive sheet; and when the hair curling tube rotates relative to the handle shell, the conductive spring needle slides along a surface of the conductive sheet. 
     
     
         3 . The electric hair curler according to  claim 2 , wherein the conductive sheet comprises a positive conductive sheet and a negative conductive sheet; the positive conductive sheet and the negative conductive sheet are both in a circular ring shape and are concentrically arranged; the conductive spring needle comprises a positive conductive spring needle and a negative conductive spring needle; the positive conductive spring needle and the negative conductive spring needle are spaced apart; the positive conductive spring needle is arranged in a manner of corresponding to the positive conductive sheet; and the negative conductive sheet is arranged in a manner of corresponding to the negative conductive spring needle. 
     
     
         4 . The electric hair curler according to  claim 3 , wherein a surface of the first electric connector is further provided with an annular isolation portion; and the isolation portion protrudes out of the surface of the first electric connector and is located between the positive conductive sheet and the negative conductive sheet. 
     
     
         5 . The electric hair curler according to  claim 4 , wherein a surface of the second electric connector is provided with an annular groove; the groove is matched with the isolation portion; and the isolation portion is inserted into the groove and is able to slide in the groove. 
     
     
         6 . The electric hair curler according to  claim 2 , wherein the conductive spring needle comprises a base, an accommodating shell, a spring, and a needle; the accommodating shell is connected to the base; the spring is inserted into the accommodating shell; the needle is at least partially inserted into the accommodating shell and is able to slide in the accommodating shell; and two ends of the spring are respectively pressed against the base and the needle. 
     
     
         7 . The electric hair curler according to  claim 2 , wherein a driving device is arranged in the handle shell; and an output shaft of the driving device is connected to the hair curling tube through the first electric connector and the second electric connector. 
     
     
         8 . The electric hair curler according to  claim 7 , further comprising a bearing assembly, wherein the bearing assembly is arranged in the handle shell; and the output shaft of the driving device is arranged in a manner of passing through the bearing assembly. 
     
     
         9 . The electric hair curler according to  claim 1 , further comprising a hair clip, wherein the hair clip is rotatably connected to the hair curling tube; and the hair clip is configured to clamp hairs between the hair clip and the hair curling tube. 
     
     
         10 . The electric hair curler according to  claim 9 , wherein the hair clip comprises a clamping plate, a pressing member, and a reset member; the clamping plate and the pressing member are arranged on two sides of a rotating shaft; and one end of the reset member is connected to the pressing member, and the other end of the reset member is pressed against the hair curling tube.
