This infrared heating system is applied to the continuous vacuuming device for thermos cups, replacing the traditional metal heating tube with an infrared heating tube 201, combined with an optimized connection structure and sealing design.

[0025] Specifically, an infrared heating system for a continuous vacuuming device for thermos cups includes a furnace body 100, a heating component 200, and a connecting component 300. The furnace body 100 is also a common cavity for the continuous vacuuming device for thermos cups. The heating component 200 is disposed inside the furnace body 100, and the connecting component 300 extends out of the furnace body 100 and is used for connecting the heating component 200.

[0026] More specifically, the furnace body 100 includes an inner wall 101 and a shell 102; at least one set of heating components 200, including an infrared heating tube 201, a high-temperature resistant OT terminal 202, a pipe clamp 203, and a ceramic bead 204; a connecting component 300, including an inner end 301 and an outer end 302 located inside and outside the furnace body 100 respectively, for connecting the infrared heating tube 201; wherein the infrared heating tube 201 is fixed to the inner wall 101 by the pipe clamp 203; the high-temperature resistant OT terminal 202 is disposed at both ends of the infrared heating tube 201; one end of the two infrared heating tubes 201 is connected by the ceramic bead 204, and the other end is connected to the inner end 301, and the outer ends 302 of the same set are connected by the ceramic bead 204.

[0027] Furthermore, the connecting assembly 300 includes a double-ended threaded screw 303 and an insulating ceramic tube 304, wherein the insulating ceramic tube 304 is sleeved on the double-ended threaded screw 303 and passes through the housing 102, with the inner end 301 and the outer end 302 located at both ends of the insulating ceramic tube 304.

[0028] The outer end 302 is provided with an end face nut 305, an end face O-ring 306, a pressure cap 307, a sealing sleeve 308, a screw 309, a spacer 310, a washer 311, a screw O-ring 312, a nut 313, a conductor 314, a long ceramic sleeve 315, and a high-frequency magnetic cap 316.

[0029] After the end face nut 305 is fitted onto the double-ended threaded rod 303, an end face O-ring 306 is provided in the fitting gap between the two, and the end face nut 305 is located on the upper end face of the double-ended threaded rod 303.

[0032] The conductor 314 is located in the middle of the nut 313. The conductor 314 includes a conductive wire. The ceramic bead 204 can be inserted into the conductive wire. After the ceramic bead 204 is inserted into the conductive wire, it is used for the connection between the high-temperature OT terminals 202 and the connection between the high-temperature OT terminals 202 and the conductor 314.

[0033] The long ceramic sleeve 315 covers the nut 313 and the conductor 314, and the top of the long ceramic sleeve 315 is pressed by the high-frequency magnetic cap 316.

Then, two nuts 313 are installed on the double-ended threaded rod 303 and press the pressure cap 307. An insulating ceramic tube 304 is installed on the other end of the sealing sleeve 308. Then, the two nuts 313 are pressed onto the end face of the insulating ceramic tube 304 and locked. An end face nut 305 is installed on one end of the sealing sleeve 308. After the entire unit is installed, it is tightened onto the heating tube installation port of the furnace body 100.

[0040] Outside the furnace body 100, a high-temperature resistant ceramic bead and a high-temperature resistant OT terminal are installed at one end of each infrared heating tube 201, and a ceramic bead 204 is also installed at the other end. The high-temperature resistant conductive wire is threaded into the ceramic bead 204, and every two infrared heating tubes 201 are connected together through the high-temperature resistant OT terminal 202. After this work is completed, every two infrared heating tubes 201 are grouped together and fixed to the inner side wall of the furnace body 100, i.e., the inner wall 101, through the pipe clamp 203.

[0041] After the above work is completed, the high-temperature OT terminal 202 is connected to the wire, installed on the double-ended threaded rod 303 and tightened with nut 313, then the long ceramic sleeve 315 is installed and tightened with high-frequency ceramic cap 316. After all the wires outside the furnace body 100 are connected, the top protective cover 401 and the side protective cover 402 are installed. On the inside of the furnace body 100, the high-temperature OT terminal 202 from the infrared heating tube 201 is installed on one end of each double-ended threaded rod 303 and tightened with nut 313, then the long ceramic sleeve 315 is installed and tightened with high-frequency ceramic cap 316. At this time, the infrared heating system has completed all the installation work.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas. It is neither necessary nor possible to exhaustively describe all implementation methods here.
