Fire disaster escape mask

Abstract

The invention relates to a fire disaster escape mask. The mask comprises a hook and loop fastener loop surface, connectors, an elastic band, a left ear sleeving ring, a mask body, a whistle, a needle,a right ear sleeving ring, a hook and loop fastener hook surface, a filtering screen, an activated carbon cotton net, a water storage layer and a skin-friendly layer; the left ear sleeving ring and the right ear sleeving ring are symmetrically arranged at the left and right ends of the mask body respectively, the elastic band is connected to the left ear sleeving ring through one connector, the hook and loop fastener loop surface is arranged at the left side of the rear end face of the elastic band, the hook and loop fastener hook surface is connected to the right ear sleeving ring through one connector, and the needle is fixedly arranged at the upper end of the whistle; through the design, the stability of wearing the mask is improved; meanwhile, when a user is trapped by a fire disaster, the user can conveniently use the whistle to make sound and report his / her position to provide convenience for rescue personnel to search for and rescue him / her. The filtering screen is arranged onthe front end face of the activated carbon cotton net, the water storage layer is arranged on the rear end face of the activated carbon cotton net, and the skin-friendly layer is arranged on the rearend face of the water storage layer; through the design, impurities and toxic gas in air can be effectively filtered out, and meanwhile water can be supplemented to the user.

Description

technical field [0001] The invention relates to the field of mask equipment, in particular to a fire escape mask. Background technique [0002] A mask generally refers to a device worn on the mouth and nose to filter the air in the mouth and nose, so as to block harmful gases, odors, and droplets from entering and leaving the wearer's mouth and nose. It is mostly made of cloth or paper. Masks can be divided into air filter masks and air supply masks. China is the first to use masks in the world. The outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air. It is best to prepare a few more masks for replacement, and they should be changed and washed once a day. The dust suppression efficiency of the mask is based on its blocking efficiency for fine dust, especially for respirable dust below 5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. The general gauze ma...
