Description

{Emergency smokemask against fire}

The present invention relates to a smoke mask, and more particularly, to a smoke mask which can be quickly worn on the spot when a noxious gas is leaked or smoke is generated in an unexpected situation such as a fire, The present invention relates to a flame-retardant mask for fire escape which can easily escape from a fire scene to a safety zone and can be stored everywhere because of its small volume and lightness, and is easy to carry.

A respirator is a tool that protects your face from smoke or toxic chemical agents, biological agents, and radioactive agents from being inhaled or adhered.

The gas mask consists of a face made of rubber and plastic, a pouch connected to the face, and a carrying pocket. A purifier is a place to purify toxic gases with clean air. Inside the purifier there is an absorbent that chemically adsorbs or decomposes toxic gases. It also contains a filter or filter that physically filters particulate matter. Although it is possible to use an absorbent that can effectively purify the agent depending on which agent is blocked, a special treated activated carbon is used as an absorbent to cope with a widespread response since it is not possible to predict which agent will be used in the military gas mask.

Since such a gas mask has to be used in chemical agents, biological agents, and radioactive agents, it is complicated in structure, large in volume, and expensive, so it is difficult to prepare for a fire in a subway station or a public place. It takes a long time and it is difficult to use for fire escape.

Therefore, in a subway station or a building used by the public, that is, in a building, a school, and a house, the cleaning ability is lower than that of a gas mask, but the structure is simple and the volume is small so that it is easy to carry and carry, A flame-retardant mask for escape is mainly used. As you can see from the name, the smoke mask does not directly inhale the toxic gas or smoke generated in the fire. When a Fire Accident Occurs Most of the human casualties are to suffocate with toxic gases or fumes generated during a fire rather than a flame.

When a fire occurs in a room, it is ignited in interior materials or furniture, and when it reaches the ceiling, the fire spreads rapidly in a horizontal direction, so that the combustion area is widened and a large amount of radiant heat promotes pyrolysis of remaining combustible materials in the room When the combustible gas and air generated at this time are mixed into the combustion range, the fire rapidly expands and the entire room is surrounded by flames. This process is called flashover phenomenon.

The time to flashover phenomenon is usually only 5 to 6 minutes, and once a flashover occurs, it is not easy to evolve. In order to reduce fire accidents, you should avoid the fire scene before the flashover occurs do.

Because the fire place can not be specified, the smoke mask for fire escape is simple in structure, small in size, light in weight, and cheap in price, , And should be able to be worn quickly and easily in the field when a real fire occurs.

In order to satisfy such a condition, the applicant manufactures a flame-retardant mask for fire escape using a polyimide film which is a thin film as shown in Fig.

As shown in Fig. 1, a filter is formed on the face of a hood composed of a polyimide film fabric such as a plastic bag with an open bottom and a closed top.

The hood is a polyimide film that can withstand for 30 minutes at 450 ° C and is excellent in chemical resistance and abrasion resistance. The filter can filter smoke and toxic gas for 5 to 10 minutes, and the reflector can be identified at a distance of 50m under a dim light source .

The filter may be made larger or thicker to keep the filter functioning longer, but it is common for smoke masks in buildings or public places to be used for disposable use. Exposure means that Golden Time, which maintains the life phenomenon, has gone out of the image. Therefore, it is necessary to increase the functionality as a smoke mask by using limited resources (such as the thickness and material of the hood, the size of the filter, etc.) very important.

In the hood, a transparent plate was formed on the filter for the purpose of securing the visibility, and a flame retardant treated neckstick was formed on the lower part of the hood to prevent the external smoke from penetrating into the interior of the hood. And a light emitting rod is formed at one side of the lower end of the hood to emit light for several hours to induce the escape.

Since the filter removes toxic gases and fumes directly, it is very important to exert its function. The activated carbon fiber ACF (Actived Carbon Fiber), which is a filter material, is a fibrous adsorbent that is fired and revived from natural fibers or artificial organic materials and chemical fibers It is fibrous activated carbon made.

It has a large surface area, uniform pore size, small pore structure, fast adsorption rate, and about 10 to 100 times of normal activated carbon.

In order to improve the function of the filter, the thickness of the filter may be made larger or the size of the filter may be made larger. However, if a flame mask for fire escape is provided once, do. However, since it is necessary to occupy such a large space for a long time without using the probabilistic little, it is very important to reduce the size and weight. In other words, if the filter is made thicker or bigger in order to increase the functionality, the smoke mask becomes bigger and heavier and requires a lot of storage space, which limits the selection of the actual user and greatly reduces the commerciality.

Therefore, it is very important to improve the performance of the filter while using limited resources such as thickness and size.

The transparency plate is a flat plate which has been treated to prevent blurring in order to ensure the visibility. The thickness is about 0.3 to 0.5 mm, and the material is polycarbonate.

If you look at the use of a portable smoke mask, put it on the spot quickly so that you do not smoke toxic gas or smoke in case of fire, and tighten your neck strap to prevent foreign toxic gases or smoke from entering the respiratory system. When humans breathe, water is released through the mouth or nose, spreading over the transparent hood and freezing. In order to prevent this discoloration, we have formed a transparent plate with anti-shrinkage treatment. However, the anti-shrinkage treatment does not completely prevent the discoloration of the discoloration, but also delays the discoloration and reduces the discoloration. That is to say, even though the use of the anti-fogging pretreatment plate is delayed, it is difficult to secure the visibility within a few minutes.

If the outside of the hood is frozen, you can wipe it off with your hands or sleeves, but you can not put your hand inside the hood in the state of joining the neck. If you untie your hand to put your hand in it, toxic gas or smoke will flow directly into it, so you will not be able to remove the stool from the transfer board by loosening your thong and putting your hand in it. If the visibility is not secured, it is difficult to evacuate to the safe area in the field of fire. Therefore, in order to remove the stain on the transfer plate, the outside of the transfer plate must be wiped with the hand to remove it by friction with the surface of the face. Is not well removed. As described above, there is a problem in that the functionality of the flame-retardant mask is significantly deteriorated because it is stuck on a transparent plate.

Korean Patent No. 10-0452167 (October 1, 2004) Korean Patent Publication No. 10-2005-0104851 (November 3, 2005)

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a filter of activated carbon fiber which can be wiped with a hood, , So that the filter can maintain the purifying ability for a longer time than the conventional filter with a limited resource, that is, a standardized thickness and size filter. Also, when the hood is worn, when the inner surface of the filter comes into close contact with the nose and mouth, due to the characteristics of the filter having a weak structural stiffness, it is difficult to breathe due to the pressed state. However, the inner surface of the filter is slightly excited So that breathing can be smoothly performed at all times.

Another object of the present invention is to provide a hood with a hood so that the hood can be attached to the forehead after the hood is worn, which is inevitably caused only by time and concentration difference, The present invention provides a flame-retardant mask for fire escape that allows quick removal of frost at any time.

In order to accomplish the above object, the present invention provides a flame-retardant mask for fire escape in which a filter capable of purifying contaminated air is provided on a hood and a face of the hood, the hood being provided with a hood in the form of a plastic bag; A filter for opening and centralizing a portion of the face of the hood to purify contaminated air during breathing; In the front of the filter, the lattice spacing is densely formed in the portion corresponding to the nose or mouth portion so that the outside air flowing through the filter during respiration is not concentrated to the portion corresponding to the nose or mouth portion, A mesh network in which the masking grid spacing is increasingly larger; A translucent plate which is bonded to the upper part of the hood and is thicker than the hood made of flexible and wrinkled hood, has a relatively structural strength so that it is curved but not crumpled, And a forehead attaching member having a plurality of suction plates formed on one side thereof and having a sparse member formed on one side thereof and adhered to a center portion of the inside of the transmitting plate and a sucker plate having a plurality of suction plates formed on the other side thereof. And a gimge gaug that sticks to the forehead with a negative pressure generated thereon.

Further, when an external force is applied to the front surface or the rear surface of the mesh net integrally bonded to the front surface of the filter, if the external force is applied to one side of the mesh net, the filter is curled elastically and elastically, Wherein a pair of upper and lower elastic rods are provided on the forehead attachment member of the gimp gimp so that the sucker plate does not stick to the opposite hood when the mask is folded and stored. Wherein the friction material of the gum gouge is made of a hygroscopic member, and when the penetration plate is brought into contact with the penetration plate, the thrown steam is absorbed and wiped away, It is made of harmless starch and dried under pressure in several pieces It is characterized by cracking finely.

According to the present invention, the air introduced through the filter is dispersed and sucked into the entire surface without being sucked only to a specific portion of the filter, so that the life of the filter can be extended by the limited filter resources and the purification ability of the filter can be maintained for a relatively longer time . Also, by using the elasticity of the mesh plate flexibly, the filter can keep the state slightly excited from the nose or mouth so that breathing can be smoothly performed.

In addition, even when the hood is turned over the head, it is possible to quickly remove the grease stuck on the inner surface of the transmission plate from the outside by hand and rub the transmission plate onto the friction member at any time. Further, a mesh crush film is formed on the back of the sucker plate formed on the back of the forehead attachment member to prevent formation of negative pressure, so that the sucker plate does not stick to the opposite hood when storing the folding mask. Also, after wearing a hood in a fire scene, pressing the sucker against the forehead can easily break the mesh crushing film, restoring the functionality of the sucker so that it can easily stick to the forehead.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 2 and 3, a hood 110 made of a polyimide film is provided. The hood 110 is open like a plastic bag, and the other is closed. Since the hood 110 must be turned upside down in case of a fire and it should be universally used regardless of age and sex, the hood 110 has a sufficient space enough to be inserted from the head to the neck of the human body.

At the lower end of the hood 110, which is open, a neckband 114 is formed which can be tightened such that poisonous gas or smoke is prevented from flowing into the hood while being turned over the head. A reflector can be formed on one side of the hood 110 so that it can be seen from afar on a fireless scene, and a tear-off treatment is performed on the lower end of the open hood to prevent the thin film hood from tearing during an emergency wearing.

A perforated filter hole 112 is formed in the center of the face of the hood 110, and a filter 120 for removing contaminants from toxic gas or smoke is formed at the time of breathing. Active carbon fiber A.C.F (Actived Carbon Fiber), a filter material, is a fibrous adsorbent and is fibrous activated carbon made by firing and reviving natural fiber, artificial organic material, and chemical fiber as raw materials. The filter 120 is such that the fibrous activated carbon is wrapped with a member such as cloth that can pass air. Such a filter is superimposed on the outer periphery of the filter 120 and the hood 110 by a filter bonding film 122 having a rectangular cross-shaped shape on the filter hole and integrally adhered or bonded to the hood 110.

A mesh network 130 is coupled to the outside of the filter 120. The mesh network 130 is coupled to the outer periphery of the mesh network and the hood 110 by a mesh mesh bonding film 132 having a square- . That is, the mesh network 130 is stacked on the outside of the filter 120. As shown in FIG. 4, when the hood 110 is worn, the mesh portion 130 has a relatively lattice spacing in the middle portion corresponding to the nose or mouth, and the mesh net 130 is made of flame retardant synthetic resin, And the lattice spacing is more aggressive as it goes outward.

Considering the process of introducing the outside air into the nose or mouth through the filter 120 after the hood 110 is worn, since the suction force is higher toward the nose or mouth, most of the outside air flows into the nose portion do. In this case, since the pollutant accumulates intensively in the filtering process, it is necessary to limit the inflow of the external air flowing in the breathing process to the specific region.

In order to disperse the air entering the specific region, the portion corresponding to the nose or mouth is dense so that the outside air does not flow well during respiration. Instead, the outside air is relatively opened to the outside . In this case, not only the center portion of the filter 120 but also the air is uniformly distributed throughout the filter 120, so that the pollutants are not concentrated, so that the pollutants can be removed for a longer period of time while enhancing the purification ability with the same filter specifications.

Also, the mesh net 130 has a higher structural strength than a hood 110 of a thin film film that is wrinkled as a flame-retardant synthetic resin material, or a nonwoven fabric or cloth-wrapped filter 120. When the hood 110 is worn by the filter 120 and the filter 120 due to the mesh network 130 having a relatively high structural strength and excellent elasticity, So that the filter 120 is not excessively adhered to the nose portion or the mouth portion.

In order to reinforce the function of bending the mesh net 130 without bending, a pair of thin rod-shaped elastic rods 140 are vertically formed on the front and back sides of the mesh net 130. When the external force is applied to one side of the face portion of the elastic bar 140, the filter 120 is not crumpled but the entire body is elastically curved to further reinforce the mesh function. When the mask is worn, It is possible to smoothly breathe without being intimidated.

Although only one elastic rod 140 may be formed across the middle portion of the mesh net 130, a pair of the upper and lower elastic rods 140 may be balanced and bent without being eccentric.

As shown in FIG. 5, a transmission plate 150 is formed on the hood 110 on the basis of the position where the filter 120 is formed. Since the hood 110 is transparent, there is no problem in securing the field of view. However, when the hood 110 is worn, the visibility can not be secured if the portion is wrinkled or frosted, so that a transparent flame retardant synthetic resin plate And a transparent substrate 150 coated with a coating so as not to be frozen is adhered to or adhered to the surface of the hood.

If the coating process is carried out so as not to allow the steaming to be frozen, the steaming does not occur at all on the throwing plate (150), but the steaming is slowed down or the concentration of frost is lowered. In this case, it is difficult to secure visibility in the field of fire because the steaming speed is lowered or the concentration is lowered. However, ).

6, 7 and 8, the gum jug 160 is formed on the upper center of the transmission plate 150, and a friction member 162 is formed on one side thereof, An attachment member 164 is formed. The friction member 162 is made of a thin, round, flat coin-like shape that is formed by bundling a fiber fabric or a cotton cloth with a fiber fabric, and is hygroscopic and absorbs moisture. The forehead attachment member 164 is made of an elastic material such as rubber and has one side bonded to the friction member 162 and the other side formed with a plurality of suckers 166. The suction plate 166 is a stretchable material such as rubber, and has a concave space formed in its center portion. When the suction plate 166 is pressed against the flat surface, a negative pressure is generated and attracting force is generated.

As shown in FIG. 8, a hydrophilic adhesive having a weak adhesive force is applied to the friction member 162 to adhere to the transmission plate 150, so that the friction member 162 is easily separated even with a small external force. That is, if the sucker 166 is pulled out of the hood with the negative pressure sticking to the forehead, the friction member 162 will quickly fall off the transmission plate 150.

As shown in FIGS. 6 and 7, a thin mesh crushing film 170 prepared by kneading and kneading starch (starch powder) is bonded to the front surface of the sucker 166. The mesh crush membrane is made of starch powder (starch powder) which is harmless to the human body and is made into a thin film having a dense lattice to be attached to the front surface of the sucker plate 166 so that the sucker plate 166 sticks to the opposite surface of the hood 110 . When the sucker plate 166 is attached to the opposite surface of the hood 110, the hood 110 should be prevented from sticking to the hood 110 when it is worn. Therefore, even when the mesh clash film 170 is contacted with the opposite side hood 170 film, the suction plate 166 is pressed so that a negative pressure is not generated.

Since the mesh crushing film 170 is starch (starch powder), it is vulnerable to impact when dried. Therefore, even when the mesh crushing membrane 170 is formed on the front surface of the sucker 166, the suction of the sucker 166 against the forehead is performed by hand, so that the mesh crushing membrane 170 is crushed to prevent the suction plate 166 from forming a negative pressure . Further, since the mesh crush film 170 is made of edible starch (starch powder), it is harmless to the human body even if it collides against the forehead.

The operation according to the present invention as described above will be described as follows.

To avoid toxic gases or fumes from the fire scene, carry or wear a pre-fitted mask. Avoiding toxic gases or smoke means that you do not drink toxic gases or smoke and escape from the fire scene, so open the hood (110) with your hands and spread it over your head.

When the hood 110 is completely turned over, the lower end of the hood is positioned on the neck. At this time, the neck strap 114 is fastened to prevent the air from entering the space between the hood 110 and the outside air.

Since the hood 110 is made of a transparent material, a view can be secured at any angle when worn. However, since the filter 120 comes to the center of the face, breathing is smooth through the filter 120, do.

When the hood 110 is turned over and the neckband 114 is tightened, the hood 110 is rounded like a balloon. At this time, since the filter 120 is integrally laminated on the mesh network filter having excellent elasticity, The filter 120 is reinforced so as not to be excessively adhered to the nose and mouth, but to be elastically balanced and flexed without being eccentric by the elastic rods 140 formed above and below the mesh net 130. Thus, It is open to the nose and close to the nose and mouth, allowing the user to breathe smoothly without confusion.

When the hood 110 is turned upside down and breathing is performed, external air of a fire scene is introduced through the nose or mouth. At this time, external air is introduced through the filter 120 and toxic gas or smoke mixed in the air is removed. Since the toxic gas or smoke is mixed with the air, the contamination of the filter portion made of the activated carbon fiber is increased as the amount of the outside air or the amount of the inflow is large. Particularly, the filter portion corresponding to the nose and mouth portion is most contaminated. The mesh net 130 stacked on the outside of the filter 120 reduces the inflow of air into the center portion where the lattice is dense, More air flows into the outside of the large mesh network. That is, the concentration of the inflow of the external air into the filter portion corresponding to the nose or mouth portion is dispersed to the entire filter 120 using the mesh density of the mesh net 130.

As shown in FIG. 9, when the hood 110 is turned upside down, the gimbal 160 is attached to the transmission plate. However, when the center of the transmission plate 150 is manually pressed, the suction plate 166 is pressed against the forehead, , The suction plate 166 is shrunk and a negative pressure is formed and attached to the forehead as shown in FIG. When the sucker plate 166 sticks to the forehead, pulling the hood 110 pulls the friction member 162 adhering to the transfer plate 150 away from the transfer plate 150 so that the gimball hole 160 is separated and attached to the forehead.

Although the hood 110 is turned upside down to secure a field of view through a bare plate 150 that is not wrinkled, the permeable plate may be coated with air to be expelled through the nose or mouth within a few minutes Because it contains a large amount of water, it becomes frozen.

It is difficult to secure the field of view because it is difficult to secure the field of view, so it is difficult to move from the fire scene to the safe place. Therefore, it is necessary to remove the steaming steam to secure the visibility. However, Since it is not possible to insert it, the translucent plate (150) must be rubbed on the face or forehead.

When the penetration plate 150 is rubbed on the forehead or face, a part of the penetration of the contact portion is removed, but when Kim is standing on the penetration plate 150, moisture is already attached to the face or forehead as dew, 10, when the user grasps the transmission plate 150 by hand from the outside of the hood and rubs the friction member 162 in the left-right direction or the up-down direction, the friction member 162 with good hygroscopicity As soon as moisture is absorbed and wiped away, the stale thorns are removed. Even if the steamed steam is removed once, the steam is re-steamed at the interval of the water. At this time, it is possible to remove the steamed steam from the friction member 162 by hand while holding the steam feed plate 150 by hand.

That is, even if the inside of the penetration plate 150 is frozen, the penetration plate 150 is gripped from the outside by hand and rubbed off by the friction member 162 of the plaster cover 160 to ensure a quick view at any time . Therefore, it is possible to secure the visibility in a state of waiting for a long time by wearing a mask at a fire scene, and it is possible to evacuate quickly and safely.
