Insulation vest

Abstract

The invention relates to the protection product technical field, and discloses an insulation vest comprising a vest body, a storage tank, and a diversion pipe; the vest body comprises an inner layer and an outer layer; a heat conduction pipe is arranged between the inner and outer layers, and connected with the storage tank outlet through the diversion pipe; a chemical heat source is stored in the storage tank. The individual insulation vest is light, portable, long in insulation lasting time, and good for people working under cold weather; the chemical heat source stored in the insulation vest storage tank can release heat through chemical reaction, and the heat energy can enter the vest body cavity through the diversion pipe so as to rise the vest body temperature, thus providing heating insulation effect; the chemical exothermic reaction forms the good heat source; the heat source is large in reaction heat release amount, low in reactant price, non-toxic in resultant, and discharged resultant cannot pollute the environment.

Description

technical field [0001] The invention relates to the technical field of protective products, in particular to a thermal insulation vest. Background technique [0002] When the human body stays in a severe cold environment for too long, it can cause frostbite all over the body, slow down the person's breathing and heart rate, and cause muscle stiffness, which can seriously lead to death. Especially in the north of my country, it is very cold in winter, and heating is usually used indoors, and the temperature difference between indoors and outdoors is relatively large. Outdoor activities are extremely unsuitable, and even lead to frostbite. In order to solve the above problems, human body heating and heat preservation equipment has emerged as the times require. [0003] In the prior art, the commonly used heat preservation and heating method is electric heating. There are heating pads that can be bound on the body, and various electric heating vests. For example, the patent CN...

AI Technical Summary

Problems solved by technology

The above-mentioned heating vests all adopt the method of electric heating, which can meet the needs of people to keep warm in winter, but the traditional electric heating vests usually have simple structure, poor comfort, and are easy to break due to metal fatigue caused by long-term use and repeated pulling. Repair and replacement It is extremely inconvenient, so the service life is relatively short; and the electric heating method requires a power supply, and outdoor workers need to carry a mobile power supply, but the mobile power supply is too small to store energy, and it is a burden for the carrier if it is too large, so it is not easy to carry , which will also affect the operation of the work
