The air-cooling tube 2 is used to pass compressed air to dissipate heat and cool the lens 1. The compressed air fed into the air-cooling tube 2 enters the air-cooling channel 201 from the compressed air inlet 202, and then is ejected from the compressed air outlet 203 along the radial direction of the cylindrical lens 3. The ejected compressed air sweeps the outer surface of the cylindrical lens 3 to remove dust. The outer surface at this location is the end face of the cylindrical lens 3. Dust removal is beneficial to keeping the cylindrical lens 3 clean, so that the dust generated during the welding process is not easy to block the cylindrical lens 3, which is beneficial to using the lens 1 to observe the environment in the furnace.

[0048] As a preferred embodiment of the lens purging structure of a furnace high-temperature endoscopic welding gun, the compressed air outlet 203 is arc-shaped, wherein the central angle of the arc is 150-180 degrees. This structure facilitates the formation of an arc-shaped air knife and improves the purging effect.

[0050] In order not to block the lens 1, the end of the air-cooling tube 2 provided with the cylindrical lens 3 is set to be a trumpet shape, wherein the compressed air outlet 203 is set between the trumpet shape and the cylindrical lens 3. This shape is conducive to expanding the field of view of one end of the air-cooling tube 2, is not easy to block the lens 1, and is conducive to using the lens 1 to observe the environment inside the furnace.

[0051] As a preferred embodiment of the lens purging structure of a high-temperature endoscopic welding gun of a kiln, it also includes a compressed air input pipe 4, a welding gun 5, a fixing ring 6 and an end cover 7, wherein the air inlet end of the air-cooling pipe 2 is rotatably arranged at one end of the compressed air input pipe 4 and is connected, the compressed air input pipe 4 is parallel to the welding gun 5 and is fixedly connected, the welding gun 5 and the compressed air input pipe 4 are both L-shaped at one end close to the air-cooling pipe 2, the welding gun 5 and the compressed air input pipe 4 pass through the fixing ring 6 and are fixedly connected, a plurality of fixing rings 6 are provided, the inner rings of which are tangent to the surfaces of the welding gun 5 and the compressed air input pipe 4, and are fixed to the welding gun 5 and the compressed air input pipe 4 by welding.

[0052] One end of the air cooling tube 2 and one end of the compressed air input tube 4 are connected in a rotating manner, so that the angle of the air cooling tube 2 is adjustable, which is convenient for adjusting the direction of the lens 1 according to usage needs. At the same time, a first anti-slip pattern 205 is provided on the outer surface of the air cooling tube 2 to prevent the hand from slipping when adjusting the angle of the air cooling tube 2.

[0053] The end cover 7 is screwed to one end of the compressed air input pipe 4 close to the air cooling pipe 2. A through hole 701 is arranged at the center of the end cover 7. One end of the air cooling pipe 2 is spherical and is rotatably arranged on the inner side of the air cooling pipe 2. The other end passes through the through hole 701. The inner diameter of the through hole 701 is larger than the outer diameter of the air cooling pipe 2, and the inner diameter of the through hole 701 is smaller than the outer diameter of the spherical shape. The inner wall of the through hole 701 and the outer surface of the spherical shape are in contact with each other. This structure is convenient for rotating the air cooling pipe 2 and also for fixing the air cooling pipe 2. When rotating, the end cover 7 is screwed to loosen it. When fixing, the end cover 7 is tightened to fix the air cooling pipe 2 on the compressed air input pipe 4 through the end cover 7.

[0056] First, the end of the compressed air input pipe 4 away from the air cooling pipe 2 is connected to the air source and compressed air is introduced. When the compressed air is delivered to the lens 1, the lens 1 is cooled down. Then, the compressed air enters the air cooling channel 201 from the compressed air input port 202, and then is ejected from the compressed air output port 203 along the radial direction of the cylindrical lens 3. The ejected compressed air sweeps the outer surface of the cylindrical lens 3 to remove dust. Through dust removal, the dust generated during the welding process is not easy to block the cylindrical lens 3, which is conducive to using the lens 1 to observe the environment in the furnace.

[0057] When the orientation of the lens 1 needs to be adjusted, the end cap 7 is screwed to loosen it, the air-cooling tube 2 is deflected to a suitable angle, and then the end cap 7 is screwed to tighten it. After tightening, the spherical end of the air-cooling tube 2 is clamped and fixed between the upper sealing ring 8 and the lower sealing ring 9.
