The arrangement of the connector can supply power to the resistance wire inside the device, so that the resistance wire can heat up quickly, thereby heating the gas. The arrangement of the steel pipe can separate the gas for transmission, thereby making the gas heating faster. At the same time, the steel pipe can measure the temperature of the gas after being heated by the device, making the temperature of the gas after being heated by the device more accurate.
