[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] Referring to Figures 1-4 A composite material-based improved heating plate structure comprises a base 1, which is a high-temperature-resistant metal plate with a rectangular shape and a slot in the middle. A first limiting plate 2 is vertically installed along the outer side edge of the top of the base 1, and a second limiting plate 3 is vertically installed along the inner side edge of the top of the base 1. The height of the second limiting plate 3 is lower than that of the first limiting plate 2, and the first limiting plate 2 and the second limiting plate 3 are also high-temperature-resistant metal plates, forming a high-temperature-resistant metal frame as the frame and base of the heating plate. When the heating plate is in use, the metal frame can effectively resist deformation during heating, ensuring the overall stability of the heating plate and avoiding structural damage caused by material expansion.

[0026] As shown in Figure 3 and Figure 4 , a plurality of spaced-apart winding columns 4 are arranged on both sides of the top of the base 1. The winding columns 4 are ceramic columns, and the bottom of the winding column 4 is fixed to the base 1 through a connecting column 5, that is, the winding column 4 is arranged between the first limiting plate 2 and the second limiting plate 3, and the front view projection position of the winding column 4 is between the first limiting plate 2 and the second limiting plate 3.

[0027] A heating wire 7 is arranged above the base 1 and is wound along the outer side of the winding column 4 and arranged in an "S" shape. At least one annular limiting groove 6 is formed along the outer side of the winding column 4 to limit the winding of the heating wire 7 on the winding column 4, ensuring the stability of the winding of the heating wire 7 on the winding column 4. The end of the heating wire 7 is connected to a power supply interface 8, and the power supply interface 8 is fixed to the outer wall of the first limiting plate 2, so that the heating wire 7 can be powered from the outside of the heating plate.

[0028] Further, a plurality of spaced-apart support columns 11 are arranged below the heating wire 7, and the ends of the support columns 11 are fixed to the inner wall of the first limiting plate 2. In actual use, the support columns 11 can provide support for the heating wire 7, ensuring the stability of the heating wire 7 and improving the support strength of the entire limiting plate.

[0029] Specifically, when the heating wire 7 is wound in an "S" shape along the plurality of winding columns 4, the spacing between adjacent winding columns 4 can regularly arrange the heating wire 7 and prevent the heating wire 7 from contacting each other, thereby preventing short circuit after power-on. The winding column 4 made of ceramic material has high temperature resistance and good insulation, and will not cause current leakage.

[0030] After the heating wire 7 is wound, a filler is poured into the first limiting plate 2, wherein the filler is one of a composite material of ceramic and metal, a composite material of ceramic and organic polymer material, and a composite material of ceramic and ceramic. The ceramic composite material is poured on the base 1 to form a complete heating plate. The thermal conductivity of the ceramic composite material can ensure the normal use of the heating plate, and the ceramic composite material has good high temperature resistance, which reduces the possibility of damage to the heating plate due to long-term heat and increases the service life of the heating plate.

[0031] It should be noted that if Figure 2 and Figure 4 As shown, a plurality of first reinforcing rods 9 are arranged at intervals on the inner side of the first limiting plate 2, and the first reinforcing rods 9 are arranged along the inner wall of the first limiting plate 2, and a plurality of second reinforcing rods 10 are arranged at intervals on the inner side of the first limiting plate 2, and the second reinforcing rods 10 are staggered and connected with the first reinforcing rods 9 to strengthen the stress strength of the first limiting plate 2, thereby reducing the possibility of the heating plate expanding outward due to heat.

[0032] Furthermore, thread grooves are provided on the outer walls of the first reinforcing rod 9 and the outer walls of the second reinforcing rod 10. When the ceramic composite material is poured on the base 1, the ceramic composite material will contact the reinforcing rod and sink into the thread groove, thereby increasing the contact surface between the first limiting plate 2 and the ceramic composite material, thereby increasing the gripping force of the first limiting plate 2 on the ceramic composite material, thereby improving the stability of the ceramic composite material in the first limiting plate 2.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
