As a preferred solution, the sealing plug is closed to the outer raft of the vent tube and has an interference fit with the vent tube.

The invention has obvious advantages and beneficial effects compared with the prior art. Specifically, it can be known from the above technical solution that since the valve piece is added on the basis of the conventional air nozzle, the valve piece is integrally formed in the soft plastic body. During the cavity, during normal inflation and deflation, the valve plate and the snorkel are kept in a gap, so that the air passage is naturally opened, and the inflation and deflation operations can be smoothly performed without pinching the soft plastic body. When in the gas storage state, the vent pipe can be pressed downward until the soft rubber body is deformed downward, and the inner sill of the snorkel is in contact with the valve plate, so that the valve piece seals the inner sputum and does not leak air, so that it can be slow Slowly cover the sealing plug to solve the drawback that the process of sealing the plug on the conventional gas nozzle is not fast enough, and the internal gas leaks a lot. The invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Please refer to the first to fifth figures, which show the specific structure of the preferred embodiment of the present invention, which is a convenient quick-filling air vent, including a soft plastic body 10, a vent pipe 20 and a sealing plug 30. .

The soft plastic body 10 has a flared shape and is integrally connected to the lower end of the vent pipe 20, and the sealing plug 30 is movably connected to the outer cymbal 21 of the vent pipe 20. A valve plate 40 is disposed in the inner cavity of the soft plastic body 10.
