Automatic inflatable life jacket principle

Inflatable life jackets are available in both manual and automatic inflation.

1. Manual inflation: Pull the rope on the inflator before or after the water is dropped, so that the rod is turned to not less than 90 degrees. The needle pierces the diaphragm of the cylinder, and the high-pressure CO2 gas is rushed into the airbag to generate buoyancy after the gas expands.

2. automatic inflation: after falling into the water, the life jacket is immersed in water to soften the water sensitive component in the automatic device, the striker loses its barrier, the spring stretches and pushes the needle to puncture the gas cylinder sealing membrane CO2 gas to fill the airbag to generate buoyancy.
   

3. The blowing nozzle is a one-way valve type, and the one-way valve is automatically closed after blowing.
