Curling irons in the prior art generally include a metal shell and an electric heating film arranged inside the metal shell, and a bracket supporting the electric heating film is also arranged inside the metal shell. However, in the prior art, the electric heating film is not tightly attached to the metal shell, resulting in reduced heat conduction efficiency; and because the contact area between the bracket and the electric heating film is too large, a large amount of heat from the electric heating film is conducted to the inside of the curling iron through the bracket, and the heat conducted to the outside of the curling iron is reduced, the heat loss is increased, and the heating efficiency is reduced, so that the temperature of the metal shell is insufficient, resulting in poor curling effect. Summary of the invention

[0014] Compared with the prior art, this application has at least the following technical effects:
[0015] 1. An air isolation chamber is provided between the bracket and the electric heating film of the curling iron of the present application. The air isolation chamber can prevent the heat of the electric heating film from being directly conducted to the bracket, thereby reducing heat loss and preventing the bracket from being damaged due to overheating, thereby improving the service life of the curling iron and further increasing the heat on the outer surface of the curling iron, thereby improving the curling effect. Moreover, since a silicone member is provided between the bracket and the electric heating film, the silicone member abuts against the bracket and the electric heating film at the same time, and the silicone member can make the electric heating film and the heat conductor in close contact, thereby improving the heat transfer efficiency between the electric heating film and the heat conductor.
[0016] 2. A groove for installing the silicone component is set on the bracket.

[0017] 3. Preferably, the silicone member is a silicone ring, the groove is arranged around the bracket, and the silicone ring is arranged around the outer periphery of the bracket, so that a stable air isolation cavity can be formed between the bracket and the electric heating film.

[0036] The following will be combined with the attached Figure 1-5 The curling iron of the present application is introduced in detail.
[0037] The present application provides a curling iron, which has a heat conductor 1 and a bracket 3. The heat conductor 1 is a tubular structure, and has a receiving cavity inside the heat conductor 1. The bracket 3 is arranged in the receiving cavity. An electric heating film 2 is also arranged in the receiving cavity. The electric heating film 2 is attached to the inner surface of the heat conductor 1. With such an arrangement, the heat generated by the electric heating film 2 can be transferred to the outer surface of the heat conductor 1, so that the hair can be styled.
[0038] In order to reduce the heat transfer between the electric heating film 2 and the bracket 3, the present application is provided with an air isolation chamber 7 between the electric heating film 2 and the bracket 3, and a silicone member 4 is provided in the air isolation chamber 7, and the silicone member 4 abuts against the bracket 3 and the electric heating film 2. With such a configuration, the air isolation chamber 7 can inhibit the heat of the electric heating film 2 from being transferred to the bracket 3, reduce heat loss, and at the same time, can increase the heat on the outer surface of the curling rod, and improve the curling effect; moreover, since the silicone member 4 is provided between the bracket 3 and the electric heating film 2, and the silicone member 4 abuts against the bracket 3 and the electric heating film 2 at the same time, the silicone member 4 can make the electric heating film 2 and the heat conductor 1 in close contact, improve the heat transfer efficiency between the electric heating film 2 and the heat conductor 1, and overcome the disadvantage of low heat conduction efficiency caused by the gap between the electric heating film and the heat conductor in the prior art. It can be understood that in the present application, the air isolation chamber 7 can be a complete cavity, and the air isolation chamber 7 can also be composed of multiple independent cavities.
[0039] In the present application, the heat conductor 1 is preferably made of a metal material with good thermal properties, for example, the heat conductor 1 can be an aluminum profile, or the heat conductor 1 can be made of other metal materials with excellent thermal conductivity. The outer periphery of the heat conductor 1 is provided with an arc surface, and the arc surface can facilitate the user to wrap the hair around its outer periphery for shaping. The outer periphery of the heat conductor 1 is radially recessed inward to form a through groove 11 extending along its axial direction, and the through groove 11 axially penetrates both ends of the heat conductor 1. With such a configuration, the user can place the hair in the through groove 11 when using the curling iron, which is convenient for the user to use the curling iron.
[0040] In order to prevent the silicone component 4 from shaking and falling off during installation and transportation, a groove 31 for installing the silicone component 4 is provided on the bracket 3 of the present application. When assembling the curling iron, first install the silicone component 4 in the groove 31 of the bracket 3, and then install the bracket 3 into the accommodating cavity of the heat conductor 1. The groove 31 can position the silicone component 4 to prevent the silicone component 4 from moving during the installation of the bracket 3, resulting in an unstable installation. Preferably, the groove 31 is convexly arranged on the outer periphery of the bracket 3, which can further increase the distance between the bracket 3 and the electric heating film 2, reduce the heat transfer between the electric heating film 2 and the bracket 3, and further improve the reliability of the curling iron.
[0041] In the present application, the silicone member 4 is preferably a silicone ring 4, and the groove 31 is arranged around the outer periphery of the bracket 3, and the silicone ring 4 is arranged to protrude from the groove 31. Such an arrangement can form a stable air isolation cavity 7 between the bracket 3 and the electric heating film 2. At the same time, the bracket 3 is in contact with the electric heating film 2 through the silicone ring 4 on all sides, which greatly reduces the contact area between the bracket 3 and the electric heating film 2 and reduces heat loss. It is understandable that in order to reduce the heat of the electric heating film 2 from being transferred to the bracket 3 along the silicone ring 4, the width of the silicone ring 4 cannot be too large. At the same time, if the silicone ring 4 is too narrow, the strength will be insufficient. The width of the silicone ring 4 is preferably between 1mm and 10mm.
[0042] In order to further improve the reliability of the installation of the silicone ring 4, in the present application, the outer diameter of the silicone ring 4 is larger than the inner diameter of the electric heating film 2, and the inner diameter of the silicone ring 4 is larger than the outer diameter of the groove 31. With such a configuration, when the bracket 3 is installed in the accommodating cavity, the silicone ring 4 can interfere with the electric heating film 2 and the bracket 3 at the same time, ensuring that the bracket 3, the silicone ring 4, the electric heating film 2, and the thermal conductor 1 can be clamped together, which can effectively avoid the shaking of the bracket 3 due to the detachment of the silicone ring 4 during transportation, thereby improving the reliability of the curling iron.
[0043] In the present application, the silicone member 4 can be provided as one or more. Preferably, there are multiple silicone members 4, and the multiple silicone members 4 are distributed along the axial direction of the bracket 3 at intervals. Such a configuration ensures the reliable assembly of the electric heating film 2 and the stability during operation and transportation.
[0044] In addition, the heat conductor 1 of the present application has an upper end cover 6 and a lower end cover 5, which are respectively covered at both ends of the heat conductor 1, and the outer periphery of the upper end cover 6 is provided with a first convex rib 61, and the outer periphery of the lower end cover 5 is provided with a second convex rib 51. The upper end cover 6 is installed on the upper end of the heat conductor 1 through the first convex rib 61, and the lower end cover 5 is installed on the lower end of the heat conductor 1 through the second convex rib 51. Such an arrangement can minimize the contact area between the upper end cover 6 and the lower end cover 5 and the heat conductor 1, and avoid the upper end cover 6 and the lower end cover 5 from overheating and melting. The upper end cover 6 and the lower end cover 5 are assembled with the bracket 3 by screws, and the outer diameters of the upper end cover 6 and the lower end cover 5 are greater than or equal to the outer diameter of the heat conductor 1, so that the heat conductor 1 is clamped and fixed by the upper end cover 6 and the lower end cover 5. In the present application, the lengths of the bracket 3 and the heat conductor 1 are equal.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present invention and will not be listed one by one here.
