[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 - Appendix Figure 3 In one embodiment of this utility model: a heat insulation cover plate 1 is provided on the top of the heat insulation frame 8, and multiple hollow layers 9 are provided around the top of the heat insulation frame 8. The heat insulation cover plate 1 is used to isolate temperature. A heating frame 11 is slidably connected to the inner wall of the heat insulation frame 8. A heating cover plate 7 is provided on the top of the heating frame 11. A connecting screw 2 is threadedly connected to the inner wall of the heating cover plate 7. Multiple heating units 10 are fixedly connected around the outer wall of the heating frame 11. The connecting screw 2 is used to press the heating cover plate 7 and the top of the heating frame 11 together.

[0032] Specifically, the heat insulation frame 8 uses a sophisticated multi-layer air sandwich structure design, and the unique structure is like a heavy checkpoint for heat. By increasing the thermal resistance of the heat dissipation channel, the heat transfer path is effectively blocked, making it difficult for heat to easily escape from the system in a high temperature environment, thereby greatly improving the heat preservation performance of the entire device. The heating cover plate 7 is carefully made of silver or copper materials with high thermal conductivity. The high-quality materials give the heating cover plate 7 excellent heat conduction performance. Its internal structure presents the characteristics of high thermal conductivity, making the temperature gradient very small during heat transfer, which can ensure uniform distribution of heat inside the cover plate. In addition, the connecting screw 2 can tightly press the heating cover plate 7 on the heating frame 11, minimizing the temperature difference that may occur between the heating cover plate 7 and the heating frame 11. The connecting screw 2 is not an ordinary screw, but a non-removable screw with a special structure, which provides a strong guarantee for the stability and safety of the entire device.

[0033] Please refer to the attached Figure 4 - attached Figure 5 The inner wall of the heating frame 11 is provided with a heating compartment 4, and the bottom of the heating frame 11 is fixedly connected with a temperature measuring unit 12. The inner wall of the heating frame 11 is threadedly connected with an adjusting screw 6, the top end of the adjusting screw 6 is floatingly connected with a positioning piece 5, and the inner wall of the positioning piece 5 is slidingly connected with an air chamber 3. The air chamber 3 is the object to be heated and processed;

[0034] Specifically, the air chamber 3 is the key object to be heated in the entire system, and has a clear target in the heating process. The main part is mainly heated and aged, and the tail pipe part of the air chamber 3 is often longer. During heating operation, this part can be flexibly extended to the outside, thereby avoiding unnecessary heating influence and ensuring the targeting and effectiveness of the heating process. In addition, in order to better adapt to the position change of different air chambers 3, the system is specially equipped with an adjusting screw 6. By rotating the adjusting screw 6, the position of the positioning piece 5 can be accurately adjusted, so that the entire device can be compatible with air chambers 3 of different specifications and placement positions, greatly improving the versatility and flexibility of the device. The temperature measuring unit 12 can accurately detect the temperature of the heating frame 11 in real time. Real-time temperature data is crucial for monitoring and controlling the entire heating process during the heating process, which provides accurate temperature information for the operator to adjust the heating parameters in time, ensuring the stability and safety of the heating process;

[0035] Please refer to the attached Figure 2 - attached Figure 4 The side wall of the heat insulation frame 8 is provided with a plurality of strip grooves 13, the inner wall of the heat insulation frame 8 is provided with a positioning groove 15 at the four corners, and the bottom of the heat insulation frame 8 is provided with an empty layer 14. The strip groove 13 is used to reduce the temperature of the outermost surface;

[0036] Specifically, the positioning groove 15 is specially designed for the accurate positioning of the heating frame 11 inside the heat insulation frame 8. It can ensure that the heating frame 11 is in an accurate and stable position inside the heat insulation frame 8. The design of the strip groove 13 fully considers safety factors. During the heating process, the temperature of the outer wall of the heat insulation frame 8 may rise, and the presence of the strip groove 13 can effectively reduce this temperature. Through specific structure and principle, the heat is dissipated, thereby avoiding the temperature of the side wall being too high to cause harm to the surrounding personnel, greatly improving the safety of the equipment in use. The air-avoiding layer 14 can reduce heat conduction and prevent heat from being transmitted in unnecessary directions, effectively improving the heat insulation performance of the entire system. The air-avoiding layer 14 also provides a suitable space for the wires, allowing the wires to be arranged safely and orderly, avoiding damage to the wires due to high temperature or other factors, and ensuring the stable operation of the electrical system. The positioning groove 15 can support the heating frame 11. In this way, the contact area between the heating frame 11 and the heat insulation frame 8 is reduced, forming a certain air-avoiding area around the heating frame 11.

[0037] Please refer to the attached Figure 3 - attached Figure 5 The bottom surface of the heat insulation frame 8 is provided with an adjusting hole 16. The material of the heat insulation cover plate 1 is temperature insulation sponge, the thickness of the air-avoiding layer 9 is one to three millimeters, the heating frame 11 is made of silver and copper, and the adjusting hole 16 is used to help the user adjust the structure of the device.

[0038] Specifically, the heat insulation cover plate 1 is carefully made of temperature insulation sponge material, which gives the heat insulation cover plate excellent heat preservation and insulation performance. It effectively blocks the transmission of heat and provides strong protection for the internal high-temperature environment. The air-avoiding layer 9 with a thickness of two millimeters utilizes the temperature gradient principle to maintain the normal working temperature of the internal high-temperature area while reducing the temperature of the contact surface with the external environment as much as possible. Because the lower the contact surface temperature, the less heat loss to the outside, the presence of the air-avoiding layer 9 further improves the temperature uniformity in the heating frame 11, making the heat distribution more uniform and stable throughout the area, creating more ideal conditions for the heating process of internal objects. In addition, the thickness of the air-avoiding layer 9 is not fixed and has certain adjustability, which can be flexibly changed between one to three millimeters according to actual needs. This flexible adjustment feature makes the device better adapt to different working scenarios and heating requirements. The heating frame 11 is made of silver or copper. Silver and copper have excellent heat conductivity, which allows heat to spread rapidly and uniformly within the heating frame 11, effectively avoiding local overheating or uneven temperature problems, and ultimately achieving the goal of improving the uniformity of the temperature in the bin, laying a solid foundation for the stable operation and efficient work of the entire heating system.

[0039] Working principle: when the aging of the atomic gas chamber is handled, first it is put into the heating bin 4, then the position of the positioning piece 5 is adjusted through rotating the adjusting screw 6 to limit the gas chamber 3, then the heating unit 10 is started to heat the heating bin 4, the heat resistance of the heat dissipation channel is increased through the heat insulation frame 8 to improve the heat preservation performance, the heat transfer capacity of the heat insulation frame 8 is reduced through the air gap layer 9 to prevent air convection.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
