[0022] When in use, the gas cylinder valve 5 is opened. At this time, the liquid carbon dioxide in the carbon dioxide storage cylinder 3 will be gasified and enter the gas guide hose 4, and then enter the main air pipe 2 through the electromagnetic gas valve 6. The gas cylinder valve 5 is a normally open valve. By controlling the state of the electromagnetic gas valve 6, the flow of carbon dioxide in the pipeline is controlled.
