What is the principle of an inflatable life jacket?

Inflatable life jackets are divided into manual and automatic, which are designed and manufactured according to European standard EN396:1993/A1:1998. The life jacket consists of a TPU air chamber, a manual inflator, a 33g CO2 gas cylinder, a jacket and a blow pipe, and a whistle. In the emergency case of falling into the water, the manual inflator can inflate the air chamber in 5 seconds. Pull the manual drawstring to inflate the air chamber and form buoyancy to ensure the safety of the drowning personnel. This product is small in size, light in weight, comfortable to wear, easy to use, suitable for life-saving use of various types of water navigation ship operators, and can also be used as personal protective equipment for leisure and lifesaving.
Before inflation: Like a vest worn on the water, when falling into the water or in distress in the water, pull the manual valve, the high pressure gas of the cylinder is filled into the life jacket, and the air is quickly inflated in 2 seconds. The front and back of the vest quickly expand to form the airbag. It can generate 10 kg of buoyancy in the water to float the human body on the water surface to achieve lifesaving. There are mouthpieces on the life jackets, and they can also be blown.
Automatic inflation "flat life jacket" after inflation: The front and back of the vest quickly swell to form a balloon, which produces 10 kg of buoyancy in the water and automatically straightens the body, tilting back 45 degrees to face up on the surface, even in a coma You can also wait for rescue on the water. The airbag is also equipped with a 3M reflective belt, a rescue whistle, and a water battery lamp for emergency use.
If the manual inflation suit is used after use, the cylinder should be replaced if it needs to be used again. Automatic life jackets need to be replaced with cylinders and tablets of water-soluble tablets for reuse. The life of a gas cylinder is generally 3 years.
