[0085] In this embodiment, gas is injected into the housing 1 through the first air inlet 21 and the second air inlet 23, and the gas is discharged from the housing 1 through the air outlet 22. The first air inlet 21 and the second air inlet 23 are located on the upper and lower sides of the air outlet 22, which enables the gas to flow evenly inside the housing 1, thereby making the gas evenly distributed inside the housing 1.

[0092] Tension spring 35 is connected between fixed base 31 and bearing base 7. Two tension springs 35 are provided, and the two tension springs 35 are symmetrically distributed with reference to the axis of the relief opening 51.

[0096] In this embodiment, when adjusting the distance between the first reflector 6 and the second reflector 8, the adjusting stud 34 is turned by the screw block 341, causing the adjusting stud 34 to drive the support column 33 to descend. The support column 33 then pushes the bearing seat 7 downward, causing the bearing seat 7 to descend, thereby reducing the distance between the first reflector 6 and the second reflector 8. Alternatively, turning the adjusting stud 34 by the screw block 341 causes the adjusting stud 34 to drive the support column 33 to rise, causing the bearing seat 7 to rise under the tension of the tension spring 35, thereby increasing the distance between the first reflector 6 and the second reflector 8. The distance adjustment operation between the first reflector 6 and the second reflector 8 is simple and convenient. Adjusting the scale lines on the outside of the adjusting stud 34 helps improve the accuracy of the distance adjustment between the first reflector 6 and the second reflector 8.

[0102] A second through cavity 312 is formed inside the fixed base 31;

[0103] A second placement groove 313 is formed on the surface of the fixed base 31, and the second placement groove 313 is connected to the second through cavity 312;

[0104] The second pin 314 is placed inside the second placement slot 313;

[0105] The bottom end of the tension spring 35 extends into the second through cavity 312 and is suspended and connected to the second pin 314.

[0106] In this embodiment, the spring is connected to the support seat 7 and the fixed seat 31 by the first pin 73 and the second pin 314, so that the tension spring 35 can accurately pull the support seat 7 and the fixed seat 31, thereby assisting in the raising and lowering of the support seat 7 and realizing the distance adjustment between the first reflector 6 and the second reflector 8.

[0107] like Figure 7 As shown, in an optional embodiment of the present invention, the height adjustment component 3 further includes:

[0111] In this embodiment, the adjusting stud 34 and the supporting stud 33 can be rotated by the connecting column 342 and the limiting block 343 in conjunction with the limiting ring 333. This allows the rotating adjusting stud 34 to drive the supporting stud 33 to slide and rise inside the fixed tube 32, thereby assisting in the height adjustment of the bearing seat 7 and the distance adjustment between the first reflector 6 and the second reflector 8. The sealing ring 331 can improve the sealing between the supporting stud 33 and the fixed tube 32, preventing gas from leaking out of the fixed tube 32.

By turning the adjusting stud 34 through the screw block 341, the adjusting stud 34 drives the support column 33 to rise and fall, cooperating with the tension spring 35 to adjust the height of the support seat 7, thereby adjusting the distance between the first reflector 6 and the second reflector 8. The adjustment operation is simple and convenient. It facilitates the disassembly of the outer shell 1, making it easier to maintain and repair the internal components. By installing the heating rod 4 in the mounting cavity 12 on the inner wall of the sleeve 11, heat is conducted... Heating is performed in a manner that facilitates the disassembly and replacement of the heating rod 4 without disassembling the outer shell 1. Gas is injected into the outer shell 1 through the first air inlet 21 and the second air inlet 23, and the gas is discharged from the outer shell 1 through the air outlet 22. The first air inlet 21 and the second air inlet 23 are located on the upper and lower sides of the air outlet 22, which allows the gas to flow evenly inside the outer shell 1, thus ensuring that the gas is evenly distributed inside the outer shell 1. By adopting a cylindrical frame 5, the avoidance opening 51 and the air inlet opening 52 can improve the overall strength of the frame 5 while meeting the requirements for light and gas entry, and prevent the frame 5 from deforming and affecting the accuracy of the light path. The frame 5 is made of cordierite sintered, which can further prevent the frame 5 from deforming under the influence of high temperature, and help ensure the accuracy of the light path.
