[0018] like Figures 1 to 3 As shown, in this embodiment, the utility model includes a tube body 1, a vortex generator 2, an air intake joint 3 and an adjusting device, the vortex generator 2 is arranged at one end of the tube body 1, the vortex generator 2 is connected to the tube body 1, the air intake joint 3 is connected to the vortex generator 2, and the adjusting device is arranged at the other end of the tube body 1.

[0019] In this embodiment, the vortex tube further includes an air outlet connector 14 , and the air outlet connector 14 is connected to the tube body 1 .

[0020] In this embodiment, the air inlet connector 3 is used for the input of compressed air. Under the action of the vortex generator 2, a vortex effect is generated, thereby separating cold and hot air flows. The cold air flow is output from the air outlet connector 14, and the hot air flow is output from the other end of the tube body 1.

[0021] In this embodiment, the adjusting device includes a sleeve 4 and an adjusting rod 5. One end of the sleeve 4 is threadedly connected to the other end of the tube body 1 for easy disassembly and assembly. The adjusting rod 5 is threadedly connected to the sleeve 4 after being inserted into the sleeve 4. An annular step 6 is provided on the inner side of the sleeve 4. A conical boss 7 is provided on the end of the adjusting rod 5. The conical boss 7 rests on the annular step 6, thereby blocking the tube body 1. When it is necessary to conduct the tube body 1, the adjusting rod 5 is rotated counterclockwise to make the conical boss 7 gradually move away from the annular step 6, so that the hot air flow is input from the tube body 1 into the sleeve 4; when the adjusting rod 5 is rotated counterclockwise, the farther the conical boss 7 moves, the larger the gap between the conical boss 7 and the annular step 6, and the larger the air flow; when the adjusting rod 5 is rotated clockwise, the conical boss 7 will gradually approach the annular step 6, and the closer the distance between the two is, the smaller the gap between the conical boss 7 and the annular step 6 is, and the smaller the air flow is; in this way, the air flow is adjusted to achieve temperature control.
