When the pressure of the secondary air cavity 5 plus the spring pre-tightening force of the check valve is greater than the pressure of the primary air cavity 15, the check valve B6 is closed. When the pressure reaches a certain value, the check valve C3 is opened under the action of the pressure difference, and the air compressed by the secondary air cavity 5 enters the air duct 4. When the pressure of the air duct 4 is gradually increased and is larger than the pressure in the three-stage air chamber 8, the one-way valve D12 is opened under the action of the pressure difference. Air in the air duct 4 enters the third-level air cavity 8 through the third-level air inlet 10;

fourthly, when the outer rod 1 drives the plunger 18 to move from left to right, the three-stage compression process comprises the following steps: the pressure in the three-stage air cavity 8 is gradually increased, and the air after three-stage compression enters the external air outlet pipe through the three-stage air outlet 11.
