The airtight ring 32 is tightly fitted to form an airtight seal on the outer surface of the American air nozzle, and the first clamping member 355 and the second clamping member 365 are pushed against the shoulder portion 214 toward the side. The direction of the top center 38 is moved such that the first clamping portion 356 and the second clamping portion 366 abut against the side of the airtight ring 32 of the click flange 381 to prevent the top core 38 from being subjected to Pushing back and retreating can reliably open the check valve of the American air nozzle.

The pump head 10 is designed in an integrally formed structure by the ejector seat 31. When the urging member 22 is cocked and pushed up against the ejector seat 31, the ejector seat 31 can directly press the airtight portion. The ring 32 is deformed to make the deformation of the airtight ring 32 good and achieve a good airtight effect. At the same time, the parts of the pump head 10 are reduced, and in addition to reducing the cost, the gap caused by the tolerance of the parts can be reduced, and the action of the head 10 of the pump is precise and reliable.
