DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0026] Example:

[0027] See also Figure 1 , Figure 2 , Figure 3 An electromagnetic heating device includes a first heating mechanism 1 and a second heating mechanism 3 installed on the outer wall of the first heating mechanism 1, wherein the first heating mechanism 1 includes an inner cylinder 11, two inner rings 12 and an inner coil 13; the second heating mechanism 3 includes an outer cylinder 31, two outer rings 32 and an outer coil 33.

[0028] Among them, the first heating mechanism 1, as the main heating component of the equipment, adopts the principle of efficient electromagnetic induction to achieve rapid conversion of electrical energy to thermal energy. The first heating mechanism 1 includes an inner cylinder 11, two inner rings 12 and an inner coil 13. The inner cylinder 11 is used as a heating core and is made of a material with good thermal conductivity, such as stainless steel or a high-temperature resistant alloy. The inner coil 13 is wound around the outer wall of the inner cylinder 11 to form an electromagnetic induction loop. The two inner rings 12 are respectively fixed at both ends of the inner cylinder 11 to strengthen the structure and fix the position. When current passes through the inner coil 13, a strong electromagnetic field is generated. According to Faraday's law of electromagnetic induction, this changing electromagnetic field will induce a current, i.e., eddy current, between the inner cylinder 11 and the outer cylinder 31. A large amount of heat will then be generated, thereby achieving a heating effect.

[0029] Among them, the second heating mechanism 3, as an auxiliary heating component, works in conjunction with the first heating mechanism 1 to improve the heating effect and uniformity. The second heating mechanism 3 includes an outer cylinder 31, two outer rings 32 and an outer coil 33. The outer cylinder 31 is wrapped around the outside of the inner cylinder 11 to form a protective layer, and also participates in the conduction of heat. The two ends of the outer cylinder 31 are fixedly connected to the copper sheet 212 through two outer rings 32, and then fixedly connected to the inner cylinder 11 through the inner ring 12 to ensure the stability and safety of the entire structure. The outer coil 33 is wound around the outer wall of the outer cylinder 31 to form a second electromagnetic induction loop. When current passes through the outer coil 33, an electromagnetic field and eddy current are also generated to generate heat. This part of the heat not only directly heats the heated object, but also supplements the heat generated by the first heating mechanism 1, making the entire heating process more uniform and efficient.

[0030] Among them, the coordinated work of the first heating mechanism 1 and the second heating mechanism 3 has been further optimized. By accurately controlling the current and frequency of the two heating mechanisms, the heating power and temperature can be accurately adjusted to meet the heating requirements of different heated objects. At the same time, the heat conduction and heat distribution between the two heating mechanisms have also been effectively optimized. By reasonably designing the gap and connection method between the inner cylinder 11 and the outer cylinder 31, it is ensured that the heat can be transferred evenly and efficiently, thereby improving the heating effect and efficiency of the entire heating system. In addition, the second heating mechanism 3 can also prevent the heat loss of the first heating mechanism 1.

[0031] See also Figure 1 , Figure 3 , Figure 4 An electromagnetic heating device includes a protective device 2 installed on the outer wall of a second heating mechanism 3, the protective device 2 consists of an internal anti-magnetic mechanism 21, an external anti-radiation mechanism 22 and a limiting mechanism 23, wherein the internal anti-magnetic mechanism 21 includes an aluminum shell 211 and a copper sheet 212; the external anti-radiation mechanism 22 includes an outer shell 221, a hollow cavity 222 and a mixture 223; the limiting mechanism 23 includes two fixing plates 231 and a plurality of hexagonal bolts 232.

[0032] Among them, the design of the internal anti-magnetic mechanism 21 prevents the leakage of electromagnetic radiation and optimizes the heat conduction efficiency. The aluminum shell 211 is designed with thicker aluminum material and is specially treated to enhance its anti-magnetic ability. The outer wall of the aluminum shell 211 is designed as a smooth curved surface to ensure a close fit with the inner wall of the external anti-radiation mechanism 22, effectively reducing the leakage of electromagnetic radiation. The copper sheet 212 also has an anti-electromagnetic radiation effect, and there is a gap between it and the second heating mechanism 3 to facilitate the winding of the outer coil 33. Under normal working conditions, electromagnetic radiation is effectively confined to the inside of the internal anti-magnetic mechanism 21, and the leakage is significantly reduced, achieving the expected anti-electromagnetic radiation effect.

[0033] The chamfering of the aluminum shell 211 and the copper sheet 212 helps to enhance the tight pressing effect therebetween. At the same time, the presence of the anti-oxidation layer effectively prolongs the service life of the equipment and reduces the performance degradation and failure risk caused by oxidation and corrosion.

[0034] Among them, the close cooperation and synergy between the external anti-radiation mechanism 22 and the internal anti-magnetic mechanism 21 enable the entire electromagnetic heating device to reach a higher level in terms of anti-electromagnetic radiation. The internal anti-magnetic mechanism 21 effectively resists the leakage of electromagnetic radiation through the combination design of the aluminum shell 211 and the copper sheet 212; while the external anti-radiation mechanism 22 further absorbs, reflects or scatters electromagnetic radiation through the combination of the shell 221, the hollow cavity 222 and the mixture 223, thereby achieving comprehensive protection against electromagnetic radiation. The shell 221 is made of high-strength and excellent radiation-resistant materials, such as special alloys or composite materials. The inner wall of the shell 221 is specially treated to ensure a close fit with the outer wall of the aluminum shell 211 to reduce the leakage of electromagnetic radiation. The hollow cavity 222 is a key part of the external anti-radiation mechanism 22, and is filled with a mixture 223. The mixture 223 is composed of a mixture of particles of multiple anti-radiation materials and has excellent anti-electromagnetic radiation performance. These materials can absorb, reflect or scatter electromagnetic radiation, thereby effectively reducing the impact of electromagnetic radiation on the surrounding environment and the human body. The shape and size of the hollow cavity 222 are designed according to the characteristics of electromagnetic radiation and the working principle of the device to ensure that the mixture 223 can fully exert its radiation resistance. At the same time, the sealing of the hollow cavity 222 is also strengthened to prevent the mixture 223 from leaking or volatilizing.

[0035] Among them, the design of the limiting mechanism 23 ensures the stable connection and precise positioning between the various components of the electromagnetic heating device. The fixing plate 231 is made of high-strength materials, such as steel plates or alloy plates, to ensure that it can withstand various forces generated by the equipment during operation. The opposite ends of the fixing plate 231 are tightly fitted with the outer shell 221, the aluminum shell 211 and the two ends of the copper sheet 212, respectively, and a seamless connection with the various components is achieved through its flat surface and precise size design. In addition, the inner wall of the fixing plate 231 is also designed with a fitting surface that matches the two ends of the outer wall of the inner cylinder 11 to ensure a tight fit with the first heating mechanism 1 to prevent heat leakage and electromagnetic radiation leakage. Several threaded holes are evenly spaced at both ends of the outer shell 221 for threaded connection with the hexagonal bolts 232. The bottom ends of the hexagonal bolts 232 pass through the outer wall edges of the two fixing plates 231 at equal intervals and are threadedly connected with the inner wall of the threaded hole. This connection method is not only firm and reliable, but also easy to disassemble and repair.

[0036] The working principle of the electromagnetic heating device: During use, the first heating mechanism 1 and the second heating mechanism 3 work together to generate heat. In particular, the heat generated by the second heating mechanism 3 collides with the heat generated by the first heating mechanism 1, thereby effectively reducing the loss of heat inside the first heating mechanism 1 and significantly improving the insulation effect of the electromagnetic heating device. Utilizing the excellent heat absorption characteristics of iron material, the device can efficiently heat the target object. At the same time, the internal anti-magnetic mechanism 21, the external anti-radiation mechanism 22 and the limiting mechanism 23 play an indispensable role in the operation of the equipment. These mechanisms work together to effectively block the thermal electromagnetic radiation generated by the first heating mechanism 1 and the second heating mechanism 3 when they are working, ensuring the safety and stability of the working environment. In addition, the design of the limiting mechanism 23 not only enhances the structural stability of the equipment, but also greatly facilitates the user to disassemble and repair the equipment, thereby ensuring that the two heating mechanisms can operate continuously and efficiently.

[0037] It should be noted that the specific model specifications of the mixture 223, the inner coil 13, and the outer coil 33 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] The power supply and principle of the inner coil 13 and the outer coil 33 are clear to those skilled in the art and will not be described in detail here.

[0039] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
