technical field

The invention relates to the technical field of protective products, in particular to a thermal insulation vest.

Background technique

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.

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 CN202425603U discloses a movable heating vest, and a rechargeable battery is installed in the vest. , The heating element and the control panel are powered by the control switch to control whether the rechargeable battery or the DC power supply is powered, and the control panel controls whether the heating element is working or not; patent CN202750754U discloses a heating vest, including a vest composed of two layers of the same fabric stitched together The cushion cover, the vest cushion cover is equipped with at least one electric heating layer composed of heating wires, at least one needle-punched cotton layer and at least one hot-rolled non-woven fabric layer, and the vest cushion cover is equipped with a waist belt; A power connector electrically connected to the heating wire is fixedly installed at a lower corner of the back waist of the vest cushion cover. The power connector is detachable and pluggable and is equipped with a multi-block temperature-controlled power supply assembly for controlling the heating temperature of the electric heating layer. 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 are usually simple in structure and not comfortable enough, and the traditional electric heating method needs power supply, and outdoor workers need to carry mobile power supply , Once the power source is removed, the thermal insulation vest will not have the thermal insulation effect.

Therefore need to design a kind of thermal insulation vest that still can continue to keep warm for a long time under the situation that does not have power supply heating.
