[0025] During use of the device, the inner tube 211 can be provided to reduce contact with the surface of the high-pressure tube 1, thereby reducing the absorption of the surface temperature of the high-pressure tube 1 by the inner tube 211. The inner insulation layer 216 formed by the combination of the first insulation tube 212 and the inner tube 211 can separate the internal heat, so that a large amount of temperature will continue to be inside the inner insulation layer 216.
