[0033] Working principle: First, move a composite fresh-keeping gas premixing device that can adjust the mixing ratio to the working position.

The ratio controller 233 automatically adjusts the electric flow regulating valve 223 according to the preset mixing ratio to ensure that different gases are mixed in a predetermined proportion. The gas with the adjusted ratio enters the mixing chamber 241. The driving motor 243 starts and drives the mixing blades 246 to rotate through the connecting shaft 244 and the connecting collar 245. The mixing blades 246 rotate in the mixing chamber 241 to achieve full mixing of different gases. In the third step, the pressure sensor 251 monitors the pressure of the mixed gas. According to the reading of the pressure sensor 251, the pressure regulating valve 252 automatically adjusts to maintain the mixed gas within an appropriate pressure range. The mixed gas is output from the mixing chamber 241 through the output pipeline 31. The output gas flowmeter 32 measures the flow of the output gas to ensure the accuracy and consistency of the output gas. In this way, the use process of a composite fresh-keeping gas premixing device that can adjust the mixing ratio is completed.
