s3, when the first piston moves from the first position point to the second position point again, the first compression cavity sucks the gas outside the first cylinder body again, the first piston performs secondary compression on the primary compressed gas to obtain secondary compressed gas, and meanwhile, the second piston moves from the fourth position point to the third position point and sucks the secondary compressed gas into the third compression cavity;

s4, when the first piston moves from the second position point to the first position point again, the second piston moves from the third position point to the fourth position point, and the second piston performs three-stage compression on the two-stage compressed gas to generate three-stage compressed gas and outputs the three-stage compressed gas to the outside of the first cylinder;
