One end of the filling nozzle 5 is connected with the container or the nitrogen filling equipment through the pipeline, and the other end is contained in the first gas exchange port 21. When the nitrogen cylinder needs to be filled with nitrogen, the filling needle 4 is pushed or rotated to open the gas valve of the cylinder port, nitrogen enters the filling nozzle 5 through the nitrogen filling equipment, and then enters the nitrogen cylinder through the first gas exchange port 21. When the nitrogen cylinder needs to fill nitrogen for other specific containers, the filling needle 4 is pushed or rotated to open the gas valve of the cylinder port, and nitrogen flows out of the nitrogen cylinder, enters the filling nozzle 5 through the first gas exchange port 21, and then enters the container that needs to be filled with nitrogen through the filling nozzle 5.

During the movement of the filling needle 4 towards the nitrogen filling cylinder, when the needle cap 41 of the filling needle 4 abuts against the needle limiting member 6, the filling needle 4 cannot move towards the nitrogen filling cylinder, thereby limiting the movement position of the filling needle 4, avoiding the damage to the nitrogen filling cylinder caused by the continuous movement of the filling needle 4 towards the nitrogen filling cylinder after the gas valve of the gas cylinder port is knocked off.
[0029] In one of the embodiments, the nitrogen filling device further comprises a gas pressure detection assembly 7, which comprises a gas pressure sensor 71 and a gas pressure display module 72, and the gas pressure sensor 71 is arranged in communication with the filling nozzle 5.
