Description

{the dry / wet mask equipped with the toxic gas cut off in the disaster evacuation and noncombustible function}

The present invention relates to a dry/wet mask, and more particularly, a dry/wet mask having a toxic gas blocking and non-combustible function during disaster evacuation that can protect people from toxic gases and flames generated during disasters such as fire or earthquake It's about the mask.

In general, in the case of disasters that generate a large amount of smoke, such as fires, wildfires, and explosives, the most basic and important evacuation method is to 'cover your nose and mouth with a wet towel, etc.' and move quickly.

In Korea, where high-rise buildings, tunnels, and subways are used a lot, there is a lot of damage from smoke and toxic gas, especially in the case of a fire. According to statistics, in case of fire, asphyxiation caused by gas and smoke accounts for more than 60% of fire deaths.

Therefore, in case of emergency, it is necessary to quickly obtain items such as towels and water to wet them.

In particular, in subway stations or buildings used by the public, that is, in buildings, schools, and houses, the purification ability is lower than that of a gas mask, but the structure is simple and small in volume, so it is easy to prepare or carry, and it is a fire that can be worn quickly. Smoke masks for evacuation are mainly used.

As the name suggests, the smoke mask is designed to prevent direct inhalation of toxic gas or smoke generated during a fire. When a fire accident occurs, most of the casualties are suffocation by inhaling poisonous gas or smoke generated during a fire rather than a flame.

When a fire occurs indoors, it ignites on interior materials or furniture, and when the fire gets bigger and reaches the ceiling, the fire spreads horizontally rapidly, expanding the combustion area and at the same time promoting thermal decomposition of the remaining combustibles in the room by a large amount of radiant heat. When the combustible gas and air generated at this time are mixed within the combustion range, the fire rapidly spreads and the entire room is engulfed in flames. This process is called a flashover phenomenon.

The time until this flashover phenomenon is usually only about 5 to 6 minutes, and since it is not easy to extinguish a fire once the flashover has taken place, in order to reduce casualties in the event of a fire, the fire site must be removed before the flashover phenomenon occurs. should be avoided

Since the location of the fire cannot be specified, the smoke mask for fire evacuation has a simple structure, small size, light weight, and low price. , it should be able to be worn quickly and easily in the field in case of an actual fire.

Since the smoke mask applied as described above was provided in the form of a dry mask that can be easily packaged and stored, it was difficult to effectively block dust, dust, and toxic gas generated during a fire.

At this time, the liquid in the water bag 400 uses hypochlorous acid water, which is colorless and odorless as it is widely used in the market. It is known as a non-irritating, high-efficiency sterilizing water.

And, as shown in FIG. 3 , the perforation needle 610 and the water bag 400 are kept in close contact between the inner pad 300 and the filter pad 200 to maintain the water bag 400 at impact. A perforated panel 600 and a fixing bag 210 capable of containing a water bag 400 are installed so that the filter pad 200 can be effectively perforated, and the fixing bag 210 is made of the same material as the filter pad 200 and has a good absorption rate. It is preferable to use it as a material, and after manufacturing the fixing bag 210 separately and embedding the perforated panel 600 and the water bag 400, the fixing bag 210 is sewn 220 on the filter pad 200. In addition, the fixing bag 210 may be formed by stitching 220 in a state in which the perforated panel 600 and the water bag 400 are superimposed on the filter pad 200 .

On the other hand, as shown in FIG. 6 , it may be somewhat cumbersome to overlap the two perforated panels 600 and the two water bags 400 to store them in the fixing bag 210 , so as shown in FIG. 8 , the two perforated panels 600 are The bending member 630 is integrally formed to maintain an appropriate distance so that it can be easily accommodated in the fixing pocket 210. At this time, since the bending member 630 is located on the wearer's nose, the bending member 630 It is desirable to form a bending groove 640 in the middle of the to facilitate the bending thereof, and as shown in FIG.

That is, the bending member 660 used at this time is the iron core material currently used in the mask, and by making it closely adhere to the bridge of the nose as shown in FIG. 11 , the sealing property could be greatly improved.

The dry/wet mask manufactured as described above is packaged in a packing paper having airtightness. It is desirable to prevent reproduction.

The operation of the dry/wet mask of the present invention as described above will be described in detail as follows.

The dry/wet mask consists of a filter pad 200 , an inner pad 300 , and an outer skin pad 100 , and two perforated panels 600 and After positioning the fixing bag 210 in which the two water bags 400 are placed, it is sewn.

At this time, as shown in FIG. 8, the bending member 630 is integrally formed so that the two perforated panels 600 can maintain an appropriate distance, and a bending groove 640 is formed in the center thereof to facilitate bending thereof, as shown in FIG. Sealability can be greatly improved by making the bending member 630 closely adhere to the bridge of the nose in the bent state.

In addition, as shown in FIGS. 10 and 11 , the perforated panel 600 is installed at a predetermined interval on both sides of the inner side between the inner pad 300 and the filter pad 200 , and the two perforated panels 600 correspond to each other. After each installation hole 650 is formed in the right place on the long side, a separately manufactured bending member 660 is connected to the installation hole 650 and installed. In this case, the bending member 660 used in the mask is currently used As an iron core material, sealing properties can be greatly improved by making it close to the bridge of the nose as shown in FIG. 11 .
