The invention provides an LNG charging machine. The LNG charging machine comprises a gun head storing sleeve embedded on a machine shell and a purging assembly arranged inside the machine shell, wherein the gun head storing sleeve is provided with an adaptive storing cavity for accommodating the gun head of a charging gun; a purging pipe communicates with the storing cavity; a purging switch is used for detecting whether the gun head is placed in the storing cavity or not, and determining according to the detection threshold value and sending a purging signal for purging the gun head to the controller; a purging control valve is used for controlling on-off of the purging pipe; and the controller is used for receiving the purging signal and controlling the purging control valve to conductthe purging pipe according to the purging signal. As the manual switch operation of workers can be replaced by the purging switch, the advantages of automatic purging operation are demonstrated. Therefore, the purging assembly
