Thermal insulation life jacket

Abstract

The invention discloses a heat preservation life jacket, and relates to the field of life jackets. The clothes body inner layer is arranged on the inner side of the clothes body surface layer and is attached to a human body; the clothes body comprises a clothes body surface layer, a clothes body inner layer and a clothes body inflation layer arranged between the clothes body surface layer and the clothes body inner layer, the clothes body inflation layer is tightly attached to the inner wall of the clothes body surface layer, and when the clothes body inflation layer is inflated, the clothes body inflation layer expands from outside to inside to squeeze out water on the inner side of the clothes body inner layer so that the normal body temperature of a human body can be kept in water. After the automatic inflation pocket encounters water, one end of the automatic inflation valve in the automatic inflation pocket is filled with the water-soluble piece assembly to react with water for automatic inflation, the jacket body inflation layer is located on the inner wall of the life jacket, inflation is conducted from outside to inside, water in the life jacket is squeezed out, and the heat preservation effect is achieved; water can be prevented from flowing backwards into the life jacket to affect the heat preservation effect.

Description

technical field [0001] The invention relates to the field of life jackets, in particular to a thermal insulation life jacket. Background technique [0002] A life jacket, also known as a life vest, is a life-saving clothing, designed like a vest, made of nylon fabric or neoprene, buoyancy or inflatable materials, reflective materials, etc. The general service life is 5-7 years. It is one of the life-saving equipment on ships and planes. It is usually vest type, made of foam plastic or cork, and has enough buoyancy when worn on the body, so that the head of the drowning person can be exposed to the water. [0003] However, at present, in the process of using the life jacket, especially in the case of falling into the water at sea, the temperature of the water body is low, because the gap area between the life jacket and the human body is easy to enter the water, resulting in the gap between the external water body and the stagnant water in the gap area. The free flow causes ...
