[0034] In one embodiment of the hair curler structure of the present utility model, please refer to Figures 1 to 5The hair curling iron structure comprises a handle 100, a central shaft 200, a rotating sleeve 300 and a rotating driving mechanism 400; the central shaft 200 is arranged at one end of the handle 100, and a first heating component 210 is arranged in the central shaft 200 for heating the central shaft 200; the rotating sleeve 300 is rotatably connected to one end of the handle 100, and a hair curling claw 310 is extended from the rotating sleeve 300, and the hair curling claw 310 is located outside the central shaft 200, and a hair curling space 320 is formed between the hair curling claw 310 and the central shaft 200; an electric heating clamp 330 is arranged on the inner side surface of the hair curling claw 310, and the electric heating clamp 330 is provided with a heating surface facing the central shaft 200; the rotating driving mechanism 400 is arranged in the handle 100 and connected to the rotating sleeve 300, and is used to drive the rotating sleeve 300 to rotate.

[0035] Specifically, since the first heating assembly 210 is provided in the central shaft 200, the hair curling claws 310 extend from the rotating sleeve 300, the hair curling claws 310 are located outside the central shaft 200, the central shaft 200 is provided at one end of the handle 100, and the rotating sleeve 300 is rotatably connected to one end of the handle 100, the hair curler is inserted into the hair, and the hair curling claws 310 can roll the hair into the hair curling space 320 and wrap around the central shaft 100 to achieve heating and shaping. Since the hair curling claws 310 are provided with electric heating clamps 330 on the inner side surface, and the electric heating clamps 330 are provided with a heating surface facing the central shaft 200, both sides of the hair in the hair curling space 320 are fully in contact with the heat source, so that the hair is heated evenly inside and outside, thereby ensuring the shaping effect of the hair curling, improving the quality of the hair curling, and saving the operation time of the hair curling. In addition, by driving the rotating sleeve 300 to rotate through the rotating driving mechanism 400, the hair curling claws 310 can automatically wind the hair around the central shaft 200, thereby achieving automatic hair curling.

[0036] Furthermore, the rotating sleeve 300 extends with multiple groups of curling claws 310, and an open groove 340 is formed between adjacent curling claws 310; the inner side of at least one group of curling claws 310 is provided with an electric heating clamp 330. Specifically, the curling claws 310 can be rotated to introduce the hair from the open groove 340 into the curling space 320, and then fully contact the central shaft 200 to achieve heating and shaping of the hair. And the hair that needs a curling effect is first positioned in the open groove 340 through the open groove 340, so that it is convenient to wrap the hair located in the open groove 340 around the central shaft 200.
