Problems solved by technology

[0002] As known, the general inner material of present lifejackets is mostly made of foamed plastic block, latex or common inflatable air bag, and its foamed plastic block raw material is not only very thick, and very hard, and volume is bigger, and activity is inconvenient, and seems very cumbersome, In addition, latex or ordinary inflatable airbags have limited waterproof and buoyancy, are not durable and uncomfortable to wear, and may have different degrees of allergic reactions, special odors, and poor thermal conductivity when wearing them.

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0030] combined with Figure 1-6 An emergency life jacket shown in , mainly consists of two parts;

[0031] The first part is life jacket material: its material can be composed of polyurethane PU, or thermoplastic elastic rubber SEBS, or a combination of polyurethane PU and SEBS; polyurethane has good thermal conductivity, flexible film, no special smell and no allergic reaction, more importantly, it is not Affected by various oil-based lubricants, polyurethane life jackets are not sensitive to humidity, heat and ultraviolet light, and are not easy to deteriorate during storage; life jackets made of them have the characteristics of non-toxicity, high strength and good thermal conductivity;

[0032] SEBS (styrene ethylene butylenes Styren) is a thermoplastic elastic rubber prepared by selective hydrogenation of styrene-butadiene block copolymer...

Abstract

The invention relates to an emergency life jacket. The emergency life jacket is mainly composed of two parts, wherein the first part is a life jacket material, which can be made of PU (polyurethane), or thermoplastic elastic rubber SEBS (Styrene Ethylene Butadiene Styrene), or PU and SEBS; the second part is an electric igniting device located on the life jacket; sodium azide, potassium nitrate and SiO2 are placed in a reaction region (4) of the electric igniting device; and in emergency, by pressing a button region (6) located on the electric igniting device, chemicals in the reaction region (4) react to instantaneously generate a large amount of nitrogen gas, generated nitrogen gas enters an air channel (2) through a filter layer (3) and finally enters an air bag through a channel (26) between an external thread (12) and an internal thread (23), and thus the life jacket is inflated to rapidly expand to save a drowning person. The emergency life jacket has the advantages of strong airtightness, high flexibility, lightweight, strong fitness, comfort in wearing, foldability, convenience in carrying and the like.

Description

technical field [0001] The invention relates to a life-saving equipment in water, in particular to an emergency life jacket. Background technique [0002] As known, the general inner material of present lifejackets is mostly made of foamed plastic block, latex or common inflatable air bag, and its foamed plastic block raw material is not only very thick, and very hard, and volume is bigger, and activity is inconvenient, and seems very cumbersome, Moreover, latex or ordinary inflatable airbags have limited water resistance and buoyancy, are not durable and uncomfortable to wear, and may have various degrees of allergic reactions, special odors, and poor thermal conductivity when wearing them. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a kind of air-tightness, high flexibility, light weight, strong fit, comfortable to wear, and can be made of polyurethane, SEBS or other synthetic polymers. A fold...
