Abstract

The utility model relates to a poison filtering box for preventing respiratory track thermal burn, include: an activated carbon cartridge comprising an activated carbon layer and a hydrogel layer. The hydrogel contains cooling factors, so that the temperature of gas passing through the hydrogel is rapidly reduced, and the active carbon part around the hydrogel can effectively adsorb harmful particles in the gas.

Description

A strain poison box for preventing respiratory track thermal burn

Technical Field

The present invention relates to the field of toxicant filtration cartridges, and more particularly, to a toxicant filtration cartridge for use in a fire mask for preventing respiratory tract heat from burning.

Background

The fire-fighting mask is a personal protection device for protecting the respiratory system, eyes and face of people from being damaged by toxic and harmful substances such as radiant heat, splashes, radioactive dust and the like. The protective effect of the fire mask depends on the protective grade of the poison filtering box, at present, the poison filtering box is used as a core component of the fire mask, and the protective performance of the mask is directly influenced by poison filtering and cooling materials filled in the poison filtering box.

The traditional toxin filtering box has achieved a good result in the aspect of toxin filtering, but has some defects in the aspect of reducing the temperature of the inhaled gas, the inhaled high-temperature gas can burn the trachea and the lung of a person to cause great damage to the human body, serious persons can threaten the life, and the reduction of the temperature of the inhaled gas to the human body bearing range has important significance in the guarantee of the life safety of fire scene evacuees and rescue workers.

Novel content

This neotype aim at provides one kind and can be used to prevent the hot burn of respiratory track, has targeted the poison filtering box of protection to high-temperature gas, under the prerequisite that realizes filtering capability, can also carry out rapid cooling to high-temperature gas.

To achieve the above objects, embodiments of the present application provide a canister for preventing thermal burns of the respiratory tract, including: an activated carbon cartridge, wherein the activated carbon cartridge comprises an activated carbon layer and a hydrogel layer.

Preferably, the poison filtering box further comprises a first filtering box and a second filtering box, wherein the first filtering box is positioned at the outer side of the activated carbon box, and the second filtering box is positioned at the inner side of the activated carbon box.

Preferably, the activated carbon cartridge further comprises a non-woven fabric and a wet gauze.

Preferably, the hydrogel layer is of a tapered configuration.

Preferably, the activated carbon cartridge further comprises a sealing membrane located on the surface of the hydrogel layer, and the sealing membrane is connected with a pull-down seal.

Compared with the prior art, the novel gas filter has the advantages that after high-temperature and harmful gas passes through the gas filter box, the hydrogel contains cooling factors, so that the temperature of the passing gas is rapidly reduced, the active carbon part around the hydrogel can effectively adsorb the harmful particles in the passing gas, and the two reach a synergistic effect, so that a user can breathe normally, and the safety is improved.

Detailed Description

To make the objects, technical solutions and advantages of the present novel embodiments clearer, the technical solutions in the present novel embodiments will be clearly and completely described below with reference to the accompanying drawings in the present novel embodiments.

Referring to fig. 1-2, in an embodiment of the present invention, a canister for a fire mask for preventing respiratory tract heat from burning includes: an activated carbon cartridge 1, wherein the activated carbon cartridge 1 comprises an activated carbon layer and a hydrogel layer 2. The active carbon layer is used for adsorbing harmful gas 5, the hydrogel contains cooling factors, so that the temperature of the passing harmful gas 5 is rapidly reduced, and the active carbon part around the hydrogel can effectively adsorb harmful particles in the passing gas.

In one example, the canister further comprises a first filter cassette 3 and a second filter cassette 4, the first filter cassette 3 being located outside the activated carbon cassette and the second filter cassette 4 being located inside the activated carbon cassette. Wherein, the first filter box 3 comprises composite filter paper, and the second filter box 4 comprises PP high-efficiency filter paper.

In one example, the activated carbon cartridge further comprises a non-woven fabric and a wet gauze.

In one example, as shown in fig. 3, the hydrogel layer 2 is a tapered structure. Wherein the conical structure causes the temperature of the passing gas to decrease rapidly.

In one example, the activated carbon cartridge further comprises a sealing membrane located on a surface of the hydrogel layer, the sealing membrane having a pull-down seal attached thereto. Before use, the seal is pulled down, the moisture-keeping seal film falls off, and the inhaled air can pass through the hydrogel.

It is obvious to a person skilled in the art that the present invention is not restricted to details of the above-described exemplary embodiments, but that it can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
