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 the case of Woori Nari, 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 human 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 it reaches the ceiling, the fire spreads horizontally rapidly, expanding the combustion area, and at the same time facilitating 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 in 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.

Therefore, in recent times, a wet mask as shown in FIG. 1 is used, and the configuration of the fire evacuation mask 100 includes a mask body 110 and a filter unit 120 . At this time, in the wet fire evacuation mask 100 , the filter unit 120 includes at least one wet filter body 130 .

However, the conventional wet mask as described above has many problems, such as a rather complicated structure, low productivity, and low efficiency for use.

Therefore, the present invention was created in consideration of the above problems, and by enabling dry and wet use according to the situation in the event of a disaster, not only improves the efficiency of the mask, but also facilitates its wearing and The purpose of the present invention is to provide a dry/wet mask equipped with a non-combustible function and blocking toxic gas during disaster evacuation so as to increase production efficiency.

The present invention was created in view of the above problems, and in a mask capable of filtering fine dust or yellow dust, comprising: a filter pad installed in the middle to filter fine dust or yellow dust; an inner pad in contact with the skin of the face while being bonded to the filter pad by bonding or sewing; It is woven with acrylic fiber and melt blown material that can block toxic gas and non-combustible functions as well as waterproof while bonding or sewing the filter pad, and wearable bands are installed on both sides of the ear. It is characterized in that it consists of an outer pad;

The present invention is also characterized in that a heat dissipation blocking pad capable of blocking high-temperature heat is installed between the filter pad and the outer pad.

In addition, the present invention is characterized in that a moisture supply pack made of a soft material is installed between the inner pad and the filter pad so as to wet the filter pad by being damaged when an external impact occurs.

The present invention is also characterized in that at least one water supply port is formed in the moisture supply pack, a stopper that detaches when an external shock is installed is installed in the water supply port, and a convex push part is formed in the middle.

In addition, according to the present invention, a moisture absorbing member is formed along the edge of one surface of the filter pad so that the water supplied from the moisture supply pack is not leaked to the outside, and the end of the water supply port of the moisture supply pack corresponds to the moisture absorbing member. characterized by one.

The present invention configured as described above has a very useful effect that can save lives by installing an outer pad on the outermost side to block toxic gas and high-temperature heat in the event of a disaster.

In addition, the present invention has a very useful effect that can save lives by installing a moisture supply pack between the inner pad and the filter pad that can be damaged during an external impact and wet the filter pad to block toxic gas and high temperature heat. .
