[0022] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0023] like Figure 1As shown in one embodiment of this utility model, the weld-free electrothermal assembly structure includes an electrothermal assembly mechanism 100, an elastic heat insulation component 200, and two side limiting adjustment components 300. The electrothermal assembly mechanism 100 includes a first electrothermal component 110 and a second electrothermal component 120. The first electrothermal component 110 and the second electrothermal component 120 are stacked side by side, and an electrothermal cavity 101 is provided between the first electrothermal component 110 and the second electrothermal component 120. An assembly gap 10 is also provided between the first electrothermal component 110 and the second electrothermal component 120. 2; The assembly gap 102 is connected to the heating cavity 101; the two side limiting adjustment components 300 are respectively connected to the two sides of the first heating component 110 and the two sides of the second heating component 120; and one of the side limiting adjustment components 300 passes through the first heating component 110 and / or the second heating component 120, and is connected to the other side limiting adjustment component 300; the elastic heat insulation component 200 is disposed inside the assembly gap 102 and is connected to the first heating component 110 and / or the second heating component 120.

[0024] The technical solution of this utility model adopts a first and second electric heating component stacked on top of each other, combined with the assembly gap between the two and an elastic heat insulation component, which can effectively adjust the cross-sectional area of ​​the electric heating cavity, thereby making it easier to adapt to the heating equipment of different specifications and improving the adaptability. In addition, the assembly and fixing effect of the two side limiting adjustment components ensures the stability of the overall structure, thereby further increasing the stability after connection.

[0025] Specifically, in some implementations, such as Figure 1 and 2 As shown, the first electric heating component 110 includes a first heat-conducting inner arc block 112 and a first heat-insulating outer arc block 111 stacked from the inside to the outside; and one of its side limiting adjustment components 300 passes through the mounting hole 103 in the first heat-insulating outer arc block 111 and is connected to the other side limiting adjustment component 300. This structure reduces heat leakage through internal electric heating and external heat insulation, thereby improving the electric heating effect. The first heat-insulating outer arc block 111 is made of polystyrene board material; and the first heat-conducting metal block is bonded to the polystyrene board material using conventional high-temperature resistant adhesive material.

[0026] Specifically, in some implementations, such as Figure 1 and 2As shown, the second electric heating component 120 includes a second heat-insulating outer arc block 121 and a second heat-conducting inner arc block 122 stacked sequentially from the outside to the inside; and one of its side limiting adjustment components 300 passes through the mounting hole 103 in the second heat-insulating outer arc block 121 and is connected to the other side limiting adjustment component 300. This structure reduces heat leakage through internal electric heating and external heat insulation, thereby improving the electric heating effect. The second heat-insulating outer arc block 121 is made of polystyrene board material; and the first heat-conducting metal block is bonded to the polystyrene board material using conventional high-temperature resistant adhesive material.

[0027] In some implementation methods, such as Figure 2 As shown, the inner walls of the first heat-insulating outer arc block 111 and the second heat-insulating outer arc block 121 are each provided with at least one first limiting groove 114; the outer surfaces of the second heat-conducting inner arc block 122 and the first heat-conducting inner arc block 112 are each provided with a first limiting protrusion 113; the outer surface of the first limiting protrusion 113 in the second heat-conducting inner arc block 122 is tightly fitted to the inner wall of the first limiting groove 114 in the second heat-insulating outer arc block 121; the outer surface of the first limiting protrusion 113 in the first heat-insulating outer arc block 111 is tightly fitted to the inner wall of the first limiting groove 114 in the second heat-insulating outer arc block 121; so as to realize the positioning and limiting effect of the first heat-conducting inner arc block 112 and the second heat-conducting inner arc block 122, thereby improving the stability of assembly.

[0028] Further, in some embodiments, both the second heat-conducting inner arc block 122 and the first heat-conducting inner arc block 112 include a heat-conducting metal block and at least one far-infrared heating tube connected inside the heat-conducting metal block; the far-infrared heating tube is arranged through the length of the heat-conducting metal block and passes through the side limiting adjustment component 300. It is preferably made of stainless steel to ensure support stability and heat conduction efficiency. The far-infrared heating tube is selected from CGHY-B or IPCH117-4 models. The working principle of the far-infrared heating tube is mainly as follows: The filament of this lamp is usually made of a material that can emit far-infrared rays. When current passes through the filament, the filament heats up and emits a large amount of far-infrared rays. Far-infrared rays have a strong thermal effect. When these far-infrared rays radiate onto an object, they cause resonance of the molecules inside the object, increasing the molecular kinetic energy and thus raising the object's temperature. It can penetrate deep into the object to achieve uniform heating.

[0029] Specifically, in some implementations, such as Figure 1As shown, the side limiting adjustment component 300 includes an upper limiting component 310, a fastener 320, and a lower limiting component 330; the upper limiting component 310 and the lower limiting component 330 are stacked side by side, and a limiting cavity 301 is provided between the upper limiting component 310 and the lower limiting component 330; the limiting cavity 301 is connected to the electric heating cavity 210; the upper limiting component 310 is connected to the first electric heating component 110; the lower limiting component 330 is connected to... The second electric heating component 120; and the two ends of the fastener 320 are detachably connected to the upper limit member 310 and the lower limit member 330 respectively, to increase or decrease the space of the limiting cavity 301; this structure controls the upper limit member 310 and the lower limit member 330, as well as the first electric heating component 110 and the second electric heating component 120 to move in opposite directions or in the opposite direction through the fastener 320, so as to adapt to heating equipment of different specifications; thereby improving the adaptability. In some embodiments, the cross-sectional area of ​​the limiting cavity 301 is larger than the cross-sectional area of ​​the electric heating cavity 210; so that neither the upper limit member 310 nor the lower limit member 330 comes into contact with the heating equipment, thereby ensuring the electric heating effect on the heating equipment and reducing the contact friction between the heating equipment, thereby ensuring the stability of the structure and the stability of use. Further, as Figure 1 and 3 As shown, the fastener 320 includes a fastening screw 321 and a fastening bolt 322; one end of the fastening screw 321 passes through the outer surface of the upper limit member 310 (the middle first connecting block), the limiting cavity 301, and the outer surface of the lower limit member 330 (the middle second connecting block), and is detachably connected to the fastening bolt 322 to achieve convenient disassembly and installation.

[0030] Specifically, in some implementations, such as Figure 1 and 3 As shown in Figure 4, the side surfaces of the upper limit member 310 and the lower limit member 330 in one of the side limit adjustment components 300 are provided with locking rods 340; one end of the locking rod 340 is provided with a locking block 341 (locking bolt); the first electric heating component 110 and the upper limit member 310 of the other side limit adjustment component 300 are disposed between the locking rod 340 and the locking block 341; the second electric heating component 120 and the lower limit member 330 of the other side limit adjustment component 300 are disposed between the locking rod 340 and the locking block 341.

[0031] Specifically, in some implementations, such as Figure 1 and 2As shown, the elastic heat insulation component 200 includes a spring 210 and a heat insulation side block 220. The spring 210 is disposed on the inner side of the heat insulation side block 220. The two ends of the spring 210 are respectively connected to the bottom side of the first heating component 110 and the top side of the second heating component 120. The heat insulation side block 220 is detachably connected to the top side of the second heating component 120 and abuts against the bottom side of the first heating component 110. The two ends of the spring 210 are respectively welded to the first heat-conducting inner arc block 112 and the second heat-conducting inner arc block 122. A positioning block 221 is provided at the bottom of the heat insulation side block 220. A positioning groove is provided on the second heat-conducting outer arc block 121. The outer side wall of the positioning block 221 is tightly fitted into the interior of the positioning groove. Further, the heat insulation side block 220 is made of polyurethane foam and foamed rubber-plastic insulation material.

[0032] In other words, during use, firstly, the first heating element 110 and the second heating element 120 are fitted onto the heated equipment, and then the heat insulation side block 220 is snapped into the assembly gap 102. Next, the locking rod 340 of one upper limit member 310 passes through the mounting hole 304 of the first heat insulation outer arc block 111 and the other upper limit member 310, and is locked with the locking block 341. Simultaneously, the lower limit member 330 passes through the mounting hole 304 of the second heat insulation outer arc block 121 and the other lower limit member 330, and is locked with the locking block 341. Then, the upper limit member 310 and the lower limit member 330 on the same side are locked and positioned using the fastening screw 321. Finally, the far-infrared heating tube is activated to heat the heated equipment.

Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model.
