[0033] This utility model proposes a hair curling iron.

[0034] In the embodiments of this utility model, such as Figures 1 to 4 As shown, the hair curler includes a handle 10, an electronic control device, and a curling tube 20. The electronic control device is located inside the handle 10. The curling tube 20 includes a ceramic heat-conducting cylinder 21 and a heating film 22 located inside the ceramic heat-conducting cylinder 21. The ceramic heat-conducting cylinder 21 is fixed to one end of the handle 10. The heating film 22 has two wiring terminals, which are electrically connected to the electronic control device.

[0035] Specifically, the electronic control device includes a circuit board and a control circuit on the circuit board, etc. Two wiring terminals are electrically connected to the control circuit so that current can be passed to the heating film 22 through the control circuit, so that the heating film 22 heats up. The specific circuit structure will not be described in detail here.

[0036] The semiconductor heat generating material (for example, an oxide semiconductor material containing one or more of zinc, aluminum, manganese, tin, cerium and yttrium) can be coated (for example, by spraying or deposition) on the inner wall of the ceramic heat conducting cylinder 21 to form the heat generating film 22, or the heat generating film 22 can be attached to the inner wall of the ceramic heat conducting cylinder 21 after the heat generating film 22 and the ceramic heat conducting cylinder 21 are respectively formed. The ceramic heat conducting cylinder 21 can be made of silicon nitride ceramic or aluminum nitride ceramic, etc. When the ceramic heat conducting cylinder 21 is used as a curling device, the ceramic material has high hardness and can make the ceramic heat conducting cylinder 21 smooth, has good oxidation resistance and durability, and can avoid additional coating on the ceramic heat conducting cylinder 21, thereby simplifying the structure of the ceramic heat conducting cylinder 21.

[0037] The curling cylinder 20 of the technical scheme of the present application has the ceramic heat conducting cylinder 21 and the heat generating film 22 arranged in the ceramic heat conducting cylinder 21, so that the heat generating film 22 can be arranged on the entire inner wall of the ceramic heat conducting cylinder 21, the heat conducting area of the heat generating film 22 and the ceramic heat conducting cylinder 21 is large, the heat generated by the heat generating film 22 can be uniformly conducted to each position of the ceramic heat conducting cylinder 21 in the circumferential direction, the ceramic heat conducting cylinder 21 is uniformly heated, and the curling effect is improved. Moreover, the heat conducting structure between the heat generating film 22 and the ceramic heat conducting cylinder 21 can be reduced, thereby simplifying the structure of the curling device and facilitating assembly.

[0038] In some embodiments, the two wiring parts are spaced apart along the length direction of the ceramic heat conducting cylinder 21, and the heat generating film 22 covers the inner wall of the ceramic heat conducting cylinder 21 and is located between the two wiring parts. In this way, the two wiring parts can be far apart, and the heat generating film 22 can generate heat sufficiently. Of course, in other embodiments, the two wiring parts can be arranged at the same end of the ceramic heat conducting cylinder 21, for example, the heat generating film 22 is arranged in a plurality of bent strips (the bent parts are arranged close to the end of the ceramic heat conducting cylinder 21, and the straight strip part extends along the length direction of the ceramic heat conducting cylinder 21).

[0039] In some embodiments, the curling cylinder 20 further comprises a cloth layer 24 covering the outer surface of the ceramic heat conducting cylinder 21. Specifically, the cloth layer 24 can be made of acetate cloth, polytetrafluoroethylene cloth or silicone cloth, etc. That is, in use, the heat of the ceramic heat conducting cylinder 21 is conducted to the cloth layer 24, and the cloth layer 24 directly contacts the hair to achieve hair perming. By arranging the cloth layer 24 on the ceramic heat conducting cylinder 21, the hair can be smoothly contacted with the cloth layer 24, so that the curling is relatively smooth, and the hair can have good anti-static effect to prevent the hair from being entangled, knotted and tangled due to static electricity. Of course, in other embodiments, the outer surface of the ceramic heat conducting cylinder 21 can be directly used to contact the hair to simplify the structure of the curling cylinder 20.

[0040] In some embodiments, the ceramic heat-conducting cylinder 21 further comprises a connecting piece 26 and two end caps 25, which are respectively arranged at two ends of the ceramic heat-conducting cylinder 21, one of the end caps 25 is connected with the handle 10, and the connecting piece 26 is arranged in the ceramic heat-conducting cylinder 21 and connects the two end caps 25. That is, the two end caps 25 are fixed on the ceramic heat-conducting cylinder 21 through the connecting piece 26, so that the ceramic heat-conducting cylinder 21 can be assembled conveniently, and the end caps 25 can protect the end of the ceramic heat-conducting cylinder 21, thereby reducing the risk of damage caused by collision of the end of the ceramic heat-conducting cylinder 21.

[0041] In some embodiments, the outer surface of the ceramic heat-conducting cylinder 21 is provided with a mounting groove 212 extending from one end to the other end of the ceramic heat-conducting cylinder 21, and the cloth layer 24 is partially arranged in the mounting groove 212. The curling cylinder 20 further comprises a fixing piece 27 arranged in the mounting groove 212 to fix the part of the cloth layer 24 arranged in the mounting groove 212, and the two ends of the fixing piece 27 are respectively fixed on the two end caps 25. Specifically, the cloth layer 24 is in a cylindrical shape to directly wrap the ceramic heat-conducting cylinder 21, or the cloth layer 24 is wrapped on the surface of the ceramic heat-conducting layer in a sheet shape. After the cloth layer 24 is wrapped on the ceramic heat-conducting cylinder 21, part (such as the seam part) of the cloth layer 24 can be arranged in the mounting groove 212, and then the fixing piece 27 is arranged in the mounting groove 212 to press the cloth layer 24 on the surface of the ceramic heat-conducting cylinder 21, so as to prevent the cloth layer 24 from sliding relative to the ceramic heat-conducting cylinder 21. In other embodiments, the cloth layer 24 can also be spirally wound on the surface of the ceramic heat-conducting cylinder 21.

[0042] In some embodiments, the end cap 25 comprises an annular portion 251 and a limiting portion 253 connected to one end of the annular portion 251, and the ceramic heat-conducting cylinder 21 is wrapped outside the annular portion 251, and the limiting portion 253 abuts against the end surface of the ceramic heat-conducting cylinder 21. Specifically, the annular portion 251 abuts against the inner wall surface of the ceramic heat-conducting cylinder 21, which can support the ceramic heat-conducting cylinder 21 and increase the contact area between the ceramic heat-conducting cylinder 21 and the end cap 25, thereby improving the installation stability of the ceramic heat-conducting cylinder 21.

[0043] In some embodiments, the end of the fixing member 27 is provided with a clamping protrusion 271, the annular portion 251 is provided with a limiting gap 252, the end of the fixing member 27 extends into the annular portion 251 from the limiting gap 252, and the clamping protrusion 271 is clamped to the inner wall of the annular portion 251. That is, when the end cover 25 is installed, the limiting gap 252 is corresponded to the fixing member 27, so that the part of the fixing member 27 adjacent to the clamping protrusion 271 extends into the limiting gap 252, and the clamping protrusion 271 is located in the annular portion 251. When the annular portion 251 of the two end covers 25 is inserted into the ceramic heat-conducting cylinder 21 to the position, the clamping protrusion 271 abuts against the inner wall of the annular portion 251, so that the fixing member 27 is fixed in the installation groove 212. Thus, the structure is simple, and the installation is convenient. Of course, in other embodiments, the fixing member 27 can be fixed to the end cover 25 by a screw.

[0044] In some embodiments, one of the end covers 25 is provided with a insertion hole 254, the handle 10 comprises a housing 11 and a connecting seat 12 provided at one end of the housing 11, the connecting seat 12 has an insertion portion 121 and a connecting hole 122 penetrating the insertion portion 121, the insertion portion 121 is inserted into the insertion hole 254, and the connecting member 26 comprises a connecting rod 261, a limiting head 262 located at one end of the connecting rod 261, and a threaded portion 263 located at the other end of the connecting rod 261, the connecting rod 261 is inserted into the connecting hole 122, the limiting head 262 abuts against the end of the connecting hole 122 away from the ceramic heat-conducting cylinder 21, and the threaded portion 263 is screwed to the end cover 25 away from the connecting seat 12.

[0045] In the installation, after the two end covers 25 are installed at the ends of the ceramic heat-conducting cylinder 21, the insertion portion 121 of the connecting seat 12 is inserted into the insertion hole 254, then the end of the connecting member 26 where the threaded portion 263 is located is inserted into the connecting hole 122 until the threaded portion 263 is screwed to the end cover 25 at the end of the ceramic heat-conducting cylinder 21 away from the handle 10, the outer diameter of the limiting head 262 is greater than the inner diameter of the connecting hole 122, so that the limiting head 262 abuts against the edge portion of the connecting hole 122, and finally the connecting seat 12 is fixed to the housing 11. Thus, the fixation of the end cover 25 to the ceramic heat-conducting cylinder 21 and the fixation of the end cover 25 to the handle 10 can be simultaneously achieved by the connecting member 26, the connecting structure between the curling cylinder 20 and the handle 10 can be reduced, and thus the structure of the curling iron is simplified.

[0046] The shape of the ceramic heat-conducting cylinder 21 can be various, for example, in the present embodiment, the ceramic heat-conducting cylinder 21 is in a cylindrical shape. In other embodiments, the ceramic heat-conducting cylinder 21 is in an elliptical cylindrical shape (refer to Figure 5 ), a prismatic shape (refer to Figure 6 ), or a conical shape (refer to Figure 7 ).
