Abstract

The present invention discloses an automatically inflatable life jacket, which comprises a hanging airbag, a container and a gas generator composed of a water inlet hole, an one-way valve, a guide groove, a water baffle board, a block and a mesh bag capable of coating with calcium carbide which are provided on the container, and a gas hose with two ends respectively connected to the airbag and the gas generator; the water baffle board is drawn when people is in danger in water, then water enters in the container and is reacted with calcium carbide, the airbag is filled with the produced air, so that the upper part of human body can be supported out of water.

Description

technical field [0001] The invention relates to a lifejacket, in particular to a lifejacket that is automatically inflated when encountering water, and belongs to the technical field of water lifesaving equipment. Background technique [0002] At present, the life-saving appliances used in water operations such as ships and docks or swimming and playing in rivers, such as life jackets and life buoys, are generally pre-filled with air for standby use, which are bulky, inconvenient to carry and use, and have low utilization and insurance coefficients; Chinese patent CN2090804U discloses a kind of " drowning automatic life preserver ", is made of air bag, gas generator and its automatic and manual control device and safety switch, and its structure is more complicated, and production cost is high, and the part chemical substance used has corrosive, safe Poor performance and applicability. Contents of the invention [0003] Aiming at the above-mentioned technical problems, th...
