Working principle of pneumatic:
Manual inflation: Before or after falling into the water, driving force of the rope to open the inflatable device, until the bar go not less than 90 degrees; When pricker broke the diaphragm of high-pressure gas cylinders, the high-pressure carbon dioxide gas break into the air bag and then buoyancy is happening.

Automatic inflation: After a life jacket falling into the water, the submerged automatic device to soften the water-sensitive components, firing pin stop loss, done to promote the firing pin spring punctured diaphragm seal carbon dioxide gas cylinder filled balloon buoyancy generated.
Inflated by mouth blown: Blowing nozzle is a one-way valve, after blowing it will be self-closed.
