The invention discloses an air nozzle structure used for an inflator. The air nozzle structure comprises an inflation needle air nozzle, a deep groove air nozzle and a shallow groove air nozzle, wherein the inflation needle air nozzle consists of a needle sleeve and a needle core; an air hole is arranged in the needle sleeve; the needle core comprises an air outlet section and a mounting section from the front to the rear, and the mounting section is inserted into the air hole; the needle sleeve comprises a mounting part, and a first connecting part and a second connecting part, which are matched with the air outlet end of the inflator; the first connecting part is arranged at the front end of the mounting part, and the second connecting part is arranged at the rear end of the mounting part; and the deep groove air nozzle is detachably connected to the first connecting part, and the shallow groove air nozzle is detachably connected to the second connecting part. The air nozzle structure has the advantages that various types of inflating openings can be adapted, and the air nozzle structure cannot be easily lost.
