The invention relates to a gas dispenser for injecting liquefied natural gas while gas is mixed in. The gas dispenser comprises a liquid phase connector, a gas phase connector, a gas injecting port, a gas return port and a pre-cooling port. The gas dispenser for injecting liquefied natural gas while gas is mixed in is further provided with a mixer and a compressor. The gas dispenser for injecting liquefied natural gas while gas is mixed in has the beneficial effects that a BOG recovery device is composed of a cold exchanger, the compressor and the mixer, BOG exhausted out of a gas cylinder in the gas injecting process and part of BOG in the gas cylinder are turned into liquid which is added into the gas cylinder again, and therefore BOG exhaust in the gas injecting process is avoided, the utilization rate of liquefied natural gas is increased, and the resource utilization rate and economic benefits are increased. 本发明涉及种气体混合加注液化天然气加气机，包括液相接口、气相接口、加气口、回气口和预冷口，所述气体混合加注液化天然气加气机还设有混合器和压缩机；本发明的有益效果是：通过冷交换器、压缩机和混合器组
