A gas filling nozzle with safety function includes a valve seat 11, a first thimble 12, a safety valve 13, an inner sleeve 14 and a first spring 15. The first thimble is sleeved in the valve seat, the safety valve is disposed at the top of the first thimble, and the inner sleeve is combined at the top of the valve seat, thereby allowing the first spring to be disposed between the inner sleeve and the safety valve. The valve seat 11 is axially formed with a stepped seat hole 111 composed of a top 112 and bottom 113 seat hole. The safety valve allows the first spring 15 and a second thimble 133 to be disposed in a top thimble hole 122 of the first thimble. The second thimble axially and elastically retracts in the hole 122 for sealing and opening a penetrated hole 131a of an end cover 131. When the gas filling nozzle is subject to a high temperature environment, the high-pressure gaseous/liquid mixture inside a gas container is able to be discharged to the exterior through the safety valve, thereby preventing the gas container from exploding. |
