What is the principle of automatic inflation of those life jackets and lifeboats?

Self-inflating life jacket is mainly composed of airbag, small high-pressure gas cylinder and automatic inflation valve, which is suitable for working and activities at sea and near water surface. Under normal circumstances (uninflated), the whole inflatable life jacket is worn on people like a vest. This product is light and compact, and it does not interfere with people's work when wearing, and overcomes the shortcomings of traditional foam life jacket such as being heavy and stuffy.

Once it falls into the water, the airbag automatically inflates, and within 5 seconds, it inflates into life jackets and lifeboats with buoyancy exceeding 15kg, so that people's heads and shoulders surface and provide safety protection. When the wearer's head falls into the water first or falls into a coma due to injury, the posture of entering the water can be automatically adjusted to keep his back up all the time, which can provide the best safety rescue.
