Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "open hole", "upper", "middle", "length", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0031] In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components is omitted in the present invention.

[0032] Embodiment 1

[0033] Please refer to Figures 1-5 As shown, in this embodiment, a thick film ceramic constant temperature heating element is provided, including: a main body 1 of the heating plate, a mounting bracket 2, a clamping component and other parts.

[0034] First of all, the main body 1 of the heating plate, as the core component, is composed of a thick film ceramic heating element 6 and a bottom plate 8. The thick film ceramic heating element 6 is designed to be able to directly contact the heat conducting plate of the straightening iron housing, so as to effectively generate and conduct heat. Two electrode plates are fixedly installed at one end of the heating element for electrical connection. The bottom plate 8 is located below the thick film ceramic heating element 6 and plays a role of support and installation and fixation.

[0035] Secondly, two mounting brackets 2 are arranged inside the straightening iron housing to clamp and support the main body 1 of the heating plate. Matching mounting structures with the main body 1 of the heating plate are designed on the opposite surfaces of the two mounting brackets 2 to ensure that the main body 1 of the heating plate can be stably installed.

[0036] In order to complete the fixed connection between the heating plate body 1 and the mounting bracket 2, the present embodiment adopts two sets of snap-fit ​​components. Specifically, two sliding holes 10 are provided at one end of the bottom plate 8, and a slider 11 is slidably connected in each sliding hole 10. A mounting plate 12 is fixedly installed on one side of the slider 11, and a clamping column 13 is fixed on the side of the mounting plate 12 away from the slider 11. At the same time, the same first elastic sheet 14 is arranged between two adjacent sliders 11; during installation, the heating plate body 1 is placed between the two mounting brackets 2, and the two adjacent sliders 11 are brought closer to each other by simultaneously moving the paddles on the sliders 11, at which time the clamping column 13 can be retracted into the bottom plate 8, and then when the bottom plate 8 is moved to a suitable position, the paddles are subsequently released, and the clamping column 13 can be automatically clamped into the mounting hole 5 by utilizing the bending force of the first elastic sheet 14 fixed in the bottom plate 8 to achieve fixation.

[0037] Furthermore, in order to improve the contact tightness between the thick-film ceramic heating plate 6 and the heat conducting plate, two movable plates 16 are arranged inside the heating plate body 1, and abutment posts 17 are fixed at the bottom of each movable plate 16. The abutment posts 17 pass through the bottom plate 8 and abut against the inner wall of the hair straightener housing. At the same time, two second elastic sheets 15 are installed on the inner wall of the top of the bottom plate 8, and the movable ends thereof are connected to the top of the movable plates 16. When the heating plate body 1 is installed, the abutment posts 17 will be close to the inner wall of the hair straightener housing, and under the deformation drive of the second elastic sheet 15, the heating plate body 1 will continue to be driven upward, so that the thick-film ceramic heating plate 6 can be closely attached to the heat conducting plate of the hair straightener housing to ensure the heat conduction efficiency.

[0038] The present application can be used in the field of heater technology, and can also be used in other fields applicable to the present application.

[0039] Example 2

[0040] refer to Figure 2 , 3 , based on the improvement of Example 1: a thick-film ceramic constant temperature heating sheet for an instant heating hair straightener, which is applied to the technical field of heaters;

[0041] In addition, a plurality of fixing plates 3 are fixed to the outer sides of the two mounting brackets 2, and the mounting brackets 2 can be firmly mounted on the hair straightener housing through fixing screws 4 threaded therethrough.

[0042] At the same time, the electrode sheet of the thick film ceramic heating sheet 6 can be connected to the electrical components of the hair straightener through the wire 9 to realize the supply of electric energy.

[0043] In order to further optimize the thermal management performance of the product, a heat insulation board 7 is installed between the thick film ceramic heating plate 6 and the bottom plate 8 to reduce the heat loss on the back of the heating plate and improve the heat conduction efficiency on the front side.

[0044] The use process and working principle of the technical solution of this utility model are as follows:

[0045] When in use, the user can first use a plurality of fixing screws 4 to fix the two mounting brackets 2 inside the hair straightener housing, and then the user can place the heating plate body 1 between the two mounting brackets 2; when installing the heating plate body 1, the user needs to simultaneously move the two sliders 11 at both ends to retract the side clamping columns 13 into the bottom plate 8; as the heating plate body 1 is gradually installed between the two mounting brackets 2, when the plurality of clamping columns 13 are aligned with the mounting holes 5 in the mounting brackets 2, the two first elastic sheets 14 in the bottom plate 8 will drive the two connected sliders 11 away from each other, and finally make the plurality of clamping columns 13 all clamped into the mounting holes 5, completing the installation of the heating plate body 1; after the heating plate body 1 is installed, the plurality of abutting columns 17 protruding from the bottom of the bottom plate 8 will abut the inner wall of the hair straightener housing, And under the action of the second elastic sheet 15, the heating plate body 1 will be continuously pushed up, which can ensure that the thick-film ceramic heating sheet 6 on the top of the heating plate body 1 can better contact the heat-conducting plate in the hair straightener shell, which is conducive to ensuring uniform heating of the hair straightener. At the same time, the elastic effect of the second elastic sheet 15 can also partially buffer the heating plate body 1, which is conducive to ensuring that the heating plate body 1 is less damaged when the device is shaken; then the two wires 9 are connected to the circuit elements of the hair straightener in turn to complete the installation of the heating plate body 1; when the user needs to replace the heating plate body 1, there is no need to disassemble the mounting bracket 2, and only the sliders 11 at both ends need to be moved at the same time to retract the multiple clamping columns 13 to complete the disassembly of the heating plate body 1. The operation is simple and fast, and it is convenient to maintain the equipment.
