Description

Technical Field

[0001] The present invention relates to the technical field of fire escape devices, and in particular to a fire escape device and a use method and a manufacturing method thereof. Background Art

[0002] Recently, fire accidents have occurred frequently in warehouses, factories, residences, and nine small places. The public's safety awareness is relatively weak. While doing a good job in comprehensive fire safety management, it is very necessary to equip certain civilian fire escape devices.

[0003] There are some obvious shortcomings in the existing fire escape protection devices. First, the simple protective equipment for fire escape on the current market is not comprehensive enough. It usually only targets the mouth and nose, lacks complete protection for the eyes, limbs and other parts of the body, and cannot provide all-round protection. Secondly, most of the existing respiratory protection devices are filtering respirators or protective masks. Although they can effectively block particulate matter in the air, such as droplets, blood, body fluids and secretions, they cannot effectively filter toxic gases (such as carbon monoxide, sulfur dioxide, hydrogen chloride and hydrogen cyanide, etc.) produced by combustion or thermal decomposition in fires. These toxic gases exist in molecular form and may quickly cause poisoning or suffocation once inhaled, significantly increasing the risk of escape. In addition, the limb protection materials commonly used on the market are mostly glass fiber fabrics. Although they have certain fire resistance, this material can cause skin itching, and fine glass fiber particles may be inhaled through the air, irritating the respiratory tract. Long-term contact may cause fibrosis or nodule formation of lung tissue, posing a potential hazard to health. Summary of the invention
