Problems solved by technology

The Chinese invention patent submitted by the applicant before, patent number 201711117997.9, provides an escape system with a small gas cylinder, which can ensure the gas supply time and allow safe escape. However, the hood selected by the escape system is made of soft materials. In a complex fire scene, when the head is collided, the protective effect of the soft material is not strong enough. If the hood has a hard shell, the protective effect will be strengthened
Moreover, the soft hood adopted in the above-mentioned patent has a large volume. If a hard shell is added, it is not easy to wear and causes a burden to the user, and the overall performance of the hood is not good.

Abstract

The invention provides a civil escape system. The civil escape system comprises an air bottle, a bottle valve pressure reducer, an air supply pipeline and a head cover, wherein the head cover is provided with an exhaust valve and a neck sealing body, the air bottle is connected with the bottle valve pressure reducer, the air supply pipeline is connected with the bottle valve pressure reducer, theair supply pipeline is connected with the head cover, and the air supply flow rate of the air bottle is 15-40 L / min. The air bottle of the escape system is small in size, convenient to carry, and capable of ensuring effective escape time while providing less air supply flow, and the oxygen supply amount in the head cover meets the requirements of human bodies and always keeps positive pressure, and is safe and effective. The head cover is small in size, convenient to wear and excellent in overall use performance.

Description

technical field [0001] The invention relates to a civilian escape system, in particular to an escape system for assisting breathing. Background technique [0002] In recent years, with the development of the economy, the level of urbanization in my country has been continuously improved, and the contradiction between the increase of urban population and the insufficient supply of urban construction land has become prominent. In order to alleviate this contradiction, people's living places tend to be high-rise. In addition, the living conditions of the people are constantly improving. House interiors, furniture items and furnishings are constantly being enriched. The improvement of living conditions has greatly improved the living comfort of the people, but at the same time there are fire safety hazards. The main reasons are: 1) House interiors, furniture and furnishings are mostly combustible materials such as wood, plastic and fabric. When a fire occurs, these materials ...
