Thermal insulation vest

Abstract

The invention relates to the technical field of protective products, and discloses a thermal insulation vest. The thermal insulation vest comprises a vest body, a storage tank, a diversion pipe and an automatic control module, an inlet is formed in the vest body, and the inlet of the vest body is connected with an outlet of the storage tank through the diversion pipe; the storage tank is provided with a storage tank switch and stores a chemical heat source, and the storage tank switch is a control switch; the automatic control module comprises a central control unit, a mobile power supply, a temperature sensor and a measuring unit; the temperature sensor, the storage tank switch and the measuring unit are electrically connected with the central control unit and the mobile power supply. When a human body feels cold, the temperature sensor transmits a low-temperature signal to the central control unit, the central control unit controls the storage tank switch to be opened, the stored chemical heat source releases heat to enter the vest body, when the temperature reaches the set temperature, the temperature transmits a high-temperature signal to the central control unit, and the central control unit controls the storage tank switch to be closed.

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
