[0036] like Figure 1 and Figure 2 As shown, the atmosphere furnace provided in this embodiment of the present invention includes: a cabinet 001, an insulation cavity shell 002, a far-infrared microcrystalline heater 003, a cabinet door 004, and an insulation door stone 005; the insulation cavity shell 002 is installed inside the cabinet 001, and the far-infrared microcrystalline heater 003 is installed inside the insulation cavity shell 002; the cabinet door 004 is movably connected to the cabinet 001; the insulation door stone 005 is connected to the inside of the cabinet door 004, and when the cabinet door 004 is closed over the cabinet 001, the insulation door stone 005 fits into the inside of the insulation cavity shell 002.

[0037] The atmosphere oven described in this embodiment uses a far-infrared microcrystalline heater 003 to uniformly heat the inside of the heat preservation chamber shell 002. By using the heat preservation door stone 005 in conjunction with the opening of the heat preservation chamber shell 002, heat leakage can be prevented, thereby improving baking efficiency and saving energy.

[0038] like Figure 1 As shown in this embodiment of the invention, the cabinet door 004 is hinged to the cabinet body 001 via a hinge 101. The cabinet body 001 is equipped with multiple clamping members 102, which are spaced apart along the edge of the cabinet door 004 and used to clamp the cabinet door 004. The clamping members 102 employ threads or snap-fit ​​structures for fastening and clamping the cabinet door 004, thereby ensuring that the cabinet door 004 tightly covers the cabinet body 001.

[0039] See Figure 2 The insulation cavity shell 002 is equipped with an insulation door frame 006 that is compatible with the insulation door stone 005. The insulation door frame 006 fits tightly with the insulation door stone 005. When the cabinet door 004 is closed, the insulation cavity shell 002, the insulation door frame 006 and the insulation door stone 005 together form a closed cavity, which can prevent heat from leaking out of the cavity.

[0040] like Figure 1 and Figure 2 As shown, the insulation cavity shell 002 protrudes from the top of the cabinet 001, and a cover plate 007 is connected to the top of the insulation cavity shell 002; the cover plate 007 is connected to a pipe 008 that connects to the inside of the insulation cavity shell 002, and a switch valve is installed in the pipe 008. The insulation cavity shell 002 may be made of asbestos, and the cover plate 007 is made of 8mm thick cold-rolled sheet metal. The cover plate 007 covers the top of the insulation cavity shell 002 to improve structural strength.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the far-infrared microcrystalline heater 003 includes: a mounting bracket 301, a pressure plate 302, and a heating plate 303; the pressure plate 302 is connected to the mounting bracket 301, and the heating plate 303 is pressed between the mounting bracket 301 and the pressure plate 302.

[0042] In this embodiment, far-infrared microcrystalline heaters 003 are installed on the top and left and right sides of the heat insulation cavity shell 002, which can achieve uniform heating inside the heat insulation cavity shell 002. Pressure plates 302 are installed on opposite sides of the mounting bracket 301, and the two pressure plates 302 press the far-infrared microcrystalline heaters 003, thereby achieving stable installation of the far-infrared microcrystalline heaters 003.

[0043] like Figure 4 and Figure 5As shown, the heating plate 303 includes: a microcrystalline glass plate 331, electrodes 332, a far-infrared heating layer 333, and an insulating layer 334. Two electrodes 332 are mounted on the microcrystalline glass plate 331, spaced apart. The far-infrared heating layer 333 is coated on the surfaces of the microcrystalline glass plate 331 and the two electrodes 332, and the insulating layer 334 is coated on the surface of the far-infrared heating layer 333. Each of the two electrodes 332 has a 5mm diameter wiring hole. The electrodes 332 are printed using high-temperature conductive silver paste or high-temperature conductive copper paste, and then cured by high-temperature baking. The far-infrared heating layer 333 is printed using graphene high-temperature conductive ink, and then cured at high temperature. The insulating layer 334 is printed using high-temperature ceramic ink, and then cured at high temperature. The above printing processes include, but are not limited to, screen printing, spraying, and scraping coating methods. The resulting heating plate 303 features high-temperature heating, rapid heating, safe surface insulation, and long service life.

[0044] Furthermore, the two electrodes 332 are respectively connected to wires 305 via bolts 304; the end of the bolt 304 that passes through the heating plate 303 and points to the inside of the insulation chamber shell 002 is connected to a ceramic nut cap 306, which insulates and seals the end of the bolt 304, thereby improving the electrical safety of the atmosphere furnace.

[0045] like Figure 1 and Figure 2 As shown, the cabinet 001 is provided with an electrical maintenance cavity 103 located below the insulation cavity shell 002; the electrical maintenance cavity 103 has a first maintenance door 104 and a second maintenance door 105 that can be opened and closed, and the first maintenance door 104 and the second maintenance door 105 are arranged opposite to each other.

[0046] To avoid the effects of high temperatures, the wiring of the circuit equipment can be set inside the circuit maintenance cavity 103. The circuit inside the circuit maintenance cavity 103 can be inspected and repaired through the first maintenance door 104 and the second maintenance door 105.

[0047] In addition, the first maintenance door 104 is equipped with an operation panel 009 connected to the far-infrared microcrystalline heater 003. The operation panel 009 can be equipped with temperature control devices, power switches, and emergency stop buttons.

[0048] Furthermore, the bottom of the cabinet 001 is equipped with casters 106, which support the cabinet 001 and facilitate its movement. In addition, the casters 106 can be equipped with a braking mechanism to lock and fix the cabinet 001 in place.

[0049] See Figure 2A cooling fan 010 is installed inside the circuit repair cavity 103. The cooling fan 010 can dissipate heat from the electronic components inside the circuit repair cavity 103, preventing the electronic components from being damaged by prolonged operation and high temperature. In addition, the cooling fan 010 can not only accelerate the airflow speed on the surface of the electronic components, but also allow the hot air inside the circuit repair cavity 103 to be discharged through the ventilation holes on the side wall or bottom of the cabinet 001.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
