[0031] In the embodiments of the utility model, as shown in the drawings, Figures 1 to 5 The straightening iron comprises a main body part and two heating assemblies 100, the main body part is provided with two clamping arms 70 which can be opened and closed, the two heating assemblies 100 are arranged on the two clamping arms 70 (that is, the heating assembly 100 is arranged on each clamping arm 70), the heating assembly 100 comprises a mounting plate 10, a ceramic plate 20 and a heating structure 30, the mounting plate 10 is provided with a mounting groove 11, the mounting groove 11 is located on one side of the mounting plate 10, the ceramic plate 20 is mounted in the mounting groove 11 and is provided with a hair straightening surface 21 located outside the mounting groove 11, and the heating structure 30 is arranged on the ceramic plate 20 and is spaced apart from the hair straightening surface 21.

[0032] Specifically, the heating assemblies 100 (hair straightening surfaces 21) on each clamping arm 70 are oppositely arranged, the hair straightening surface 21 is the surface in contact with the hair during use, and the hair straightening surface 21 is higher than the groove edge of the mounting groove 11 or is flush with the groove edge of the mounting groove 11. During use, the heating assemblies 100 (hair straightening surfaces 21) on the two clamping arms 70 can jointly clamp the hair.

[0033] The utility model technical scheme sets the mounting groove 11 on one side of the mounting plate 10, directly installs the ceramic plate and the heating structure 30 arranged on the ceramic plate in the mounting groove 11, sets the hair straightening surface 21 of the ceramic plate 20 outside the mounting groove 11, during use, the heating structure 30 directly conducts heat to the ceramic plate 20 after heating, and then directly contacts the hair through the hair straightening surface 21 of the ceramic plate 20 to realize hair straightening, so that the intermediate heat conduction structure is reduced, the heat conduction path can be reduced, heat loss can be reduced, the heat conduction efficiency and the heating speed can be effectively improved, the waiting time of the user after starting can be reduced, and the electric energy can be saved.

[0034] In some embodiments, the bottom wall of the mounting groove 11 is provided with a wire hole 14, and the heating structure 30 has a wiring portion located on the side of the ceramic plate 20 away from the ironing surface 21 and located in the wire hole 14. In this way, the wiring portion can be conveniently arranged on the ceramic plate 20, and wiring during assembly is facilitated. Of course, in other embodiments, the wiring portion can be arranged at the end of the heating structure 30 / ceramic plate 20.

[0035] In some embodiments, the wire hole 14 is located at one end of the mounting plate 10. When the heating assembly 100 is assembled into a straightening iron, the end where the wire hole 14 is located can be arranged close to the circuit board to facilitate wiring and reduce the length of the wire. Alternatively, the wire hole 14 is spaced from the end face of the mounting plate 10, so that a notch can be avoided at the end of the mounting plate 10, and the influence of the arrangement of the wire hole 14 on the structural strength of the mounting plate 10 can be reduced; or the wire hole 14 extends to the end face of the mounting plate 10.

[0036] In some embodiments, the heating structure 30 includes a heating circuit which is integrally sintered and formed inside the ceramic plate 20. Specifically, the heating circuit can be formed by printing a metal heating resistor paste; or by using a resistance wire, etc. For example, a metal tungsten or molybdenum manganese high-melting-point metal heating resistor paste can be printed on a ceramic green body, and then the ceramic plate 20 can be formed by hot pressing lamination and sintering.

[0037] In other embodiments, the heating structure 30 is arranged on the side of the ceramic plate 20 away from the ironing surface 21. That is, the heating structure 30 can be arranged on the side of the ceramic plate 20 away from the ironing surface 21 after the ceramic plate 20 is formed, so that the production cost of the ceramic plate 20 can be reduced. The heating structure 30 is a ceramic heating body (MCH). When the heating structure 30 is a ceramic heating body, the heating structure 30 and the ceramic plate 20 are fixed by sintering, gluing or laser welding.

[0038] When the heating structure 30 is arranged on the side of the ceramic plate 20 away from the ironing surface 21, the bottom wall of the mounting groove 11 is optionally provided with a receiving groove 12 which is spaced from the side wall of the mounting groove 11, the heating structure 30 is located in the receiving groove 12, and the side of the ceramic plate 20 away from the ironing surface 21 abuts against the bottom wall of the receiving groove 12. In this way, when the width of the heating structure 30 is smaller than the width of the ceramic plate 20, the ceramic plate 20 can be effectively supported by the bottom wall of the mounting groove 11, and the installation reliability of the ceramic plate 20 can be improved. Making the width of the heating structure 30 smaller can reduce the difficulty and cost of forming.

[0040] In other embodiments, the bottom wall of the mounting groove 11 is provided with a through hole, and the temperature sensing device 60 is arranged in the through hole and abuts against the ceramic plate 20.

[0044] In some embodiments, the heat generating assembly 100 further comprises a limiting piece 40, which is detachably mounted on the mounting structure and abuts against the side of the temperature sensing device 60 away from the ceramic plate 20. Specifically, the side edges of the mounting plate 10 along the length direction are spaced apart from the protruding ribs 13, and each protruding rib 13 is provided with an assembly portion 131 on the side away from the other protruding rib 13. Each protruding rib 13 is provided with a limiting portion 132 on the side facing the other protruding rib 13. The limiting piece 40 is mounted on the two protruding ribs 13, specifically, the limiting piece 40 is mounted on the assembly portion 131 of the two protruding ribs 13 or mounted on the limiting portion 132 of the two protruding ribs 13.

Of course, in other embodiments, a pressing plate can be pressed on the edge portion of the ceramic plate 20 to press the ceramic plate 20 in the limiting slot 111, and the pressing plate is welded or connected with the mounting plate 10 by screws.

[0047] In the above embodiments, the slot side wall of the mounting slot 11 can be perpendicular to the slot bottom wall of the mounting slot 11, and the limiting slot 111 can be formed by recessing the slot side wall; or the slot side wall of the mounting slot 11 can be inclined relative to the slot bottom wall of the mounting slot 11 and the slot side wall and the slot bottom wall form an acute angle, so that the limiting slot 111 is formed between the top of the slot side wall and the slot bottom wall, that is, the mounting slot 11 forms a dovetail slot structure, and the side surface of the clamping portion 23 is correspondingly provided as an inclined surface (that is, the cross section of the ceramic plate 20 is substantially trapezoidal), so that the structure of the ceramic plate 20 can be simplified and the molding is facilitated.
