[0029] Working Principle: During operation of the mixed gas distribution equipment, the first motor 2 drives the double-acting screw 22 to rotate, which in turn drives the lifting plate 23 to reciprocate. Simultaneously, the lifting plate 23 drives the first transmission rod 25 and the piston plate 27 to reciprocate synchronously. The sliding rod 24 limits the lifting plate 23 to prevent it from rotating with the double-acting screw 22. Then, the connecting rod 26 simultaneously drives the piston plate 27 and the first one-way valve 28 to reciprocate synchronously. When the piston plate 27 moves downwards, the first one-way valve 28 closes, and external air is drawn in through the intake pipe 211. Simultaneously, the second one-way valve 212 opens, allowing gas to enter the top of the metering tank 210. Afterwards, the piston plate 27 and the first one-way valve 28 move upwards, while the second one-way valve 212 closes, and the first one-way valve... When valve 28 is opened, gas flows into the bottom of metering tank 210 through the first one-way valve 28. Then, piston plate 27 and the first one-way valve 28 move down, the second one-way valve 212 opens, the third one-way valve 214 opens, and the first one-way valve 28 closes. External gas is extracted again through inlet pipe 211, while gas at the bottom of piston plate 27 enters the second outlet pipe 213 through the third one-way valve 214 and is then transported into mixing cylinder 1 through the second outlet pipe 213. At the same time, the second motor 3 drives the reverse fan blade 33 and the forward fan blade 32 to rotate through the second transmission rod 31, stirring and mixing the gas transported in through the second outlet pipe 213. The gas is then transported to the top of mixing cylinder 1 by air supply fan 35, so that the gas can be mixed more efficiently through the forward fan blade 32 and the reverse fan blade 33.
