1 is a perspective view schematically showing a configuration of a pouch type fire extinguishing apparatus according to an embodiment.

Referring to FIG. 1, in the pouch type fire extinguishing system 1, when a fire occurs, the extinguishing material 10 having received heat transmitted from the outside expands, and the pouch 20 is ruptured due to the expansion of the extinguishing material 10 The fire extinguishing material 10 is discharged to the outside to extinguish the fire. The pouch type fire extinguishing system 1 is formed with a simple structure including the extinguishing material 10 therein, and has an advantage that it can be attached to a desired position individually by minimizing its own weight. The pouch type fire extinguishing system 1 may also include a housing (not shown) that houses the pouch 20 therein and protects the pouch 20.

The pouch type fire extinguishing system 1 may include a fire extinguishing material 10 and a pouch 20. [

The extinguishing material (10) expands when subjected to heat. In other words, the extinguishing material 10 can be made of various materials that are vaporized upon heating. When the extinguishing material 10 is heated and expanded, it can be released through the pouch 20 to evolve the fire. For example, the extinguishing material 10 may comprise a fluorinated ketone.

Fluorinated ketones are colorless, odorless, nearly viscous, and weigh 1.7 times heavier than water. Fluorinated ketones have a stable property of fluorine, which constitutes a foreign substance when they are immersed in an electronic product, so that electricity does not pass through and does not cause a reaction such as oxidation with the contacted substance. In addition, when the fluorinated ketone is sprayed to a fire site, since it evaporates quickly upon contact with fire and smoke, it can be effective in suppressing the fire of electronic products because it does not remain in the object while it is taken away.

The pouch 20 is in the form of a pouch, which is a kind of bag made by sealing the flexible packaging material 21, 22. The pouch 20 may be deformed when the fire extinguishing material 10 is accommodated therein due to the characteristics of the flexible packaging materials 21 and 22. The pouch 20 is preferably in the form of a slope sealing pouch. When the pouch 20 is formed of a slope sealing pouch, all of the edges of the packaging material may be suitable for holding the shape when the digesting material 10 is accommodated in a joined state. However, the present invention is not limited thereto, and the pouch 20 may be in the form of a back side sealed pouch or a three-side sealed pouch.

The pouch 20 forms a joint space 23 formed by joining the edges of at least one of the packaging materials 21 and 22 and an accommodation space S in which the extinguishing material 10 is accommodated. For example, the pouch 20 faces the accommodation space S and the first package 21 and the second package 22 are joined to each other. At this time, the first package 21 and the second package 22 of the pouch have a shape corresponding to each other, and the rims of the first package 21 and the second package 22 are joined to each other to form a joint 23 and seal the accommodation space S. The joining portion 23 supports the rim of the pouch 20 so that the shape of the pouch 20 can be maintained.

The pouch 20 can rupture when the extinguishing material 10 accommodated in the accommodation space S expands by heat and can discharge the extinguishing material 10 to the outside.

2 is a cross-sectional view schematically showing the structure of a packaging material according to an embodiment.

2, the packaging material 21, 22 is a multi-layer structure composed of a protective layer 211 and a coating layer 212.

The protective layer 211 shields ultraviolet rays and protects the extinguishing material 10 from external heat. The protective layer 211 may include an aluminum material. However, the present invention is not limited thereto, and all the materials that shield ultraviolet rays and protect the extinguishing material from external heat may be possible.

In the case where the protection layer 211 is formed solely, the pouch type fire extinguishing system 1 is a type of fire extinguishing system that can be used for a fire extinguisher, Can cause other damage. In addition, the pouch type fire extinguishing system 1 may generate heat due to resistance by electrical conduction of the protection layer 211, causing a problem that the fire extinguishing material 10 is expanded due to the temperature rise of the protection layer 211 . Accordingly, the coating layer 212 may be formed on both sides of the protective layer 211 to prevent electric conduction, thereby preventing these problems.

The coating layer 212 is formed on both sides of the protective layer 211. The coating layer 212 is formed of a nonconductive material to prevent electric conduction to the protective layer 211. For example, the coating layer 212 may be formed of a nonconductive material such as polypropylene (PP), oriented polypropylene (OPP), polyvinyl chloride (PVC), or polyethylene terephthalate (PET) . The material of the coating layer 212 is not limited and may be any material that is coated on the entire surface of the protective layer 211 to prevent conduction of the protective layer 211.

3 is a rear view of the pouch type fire extinguishing system according to one embodiment.

Referring to FIG. 3, the pouch 20 is formed with a check window 24 for identifying the accommodation space S in the package. For example, a confirmation window 24 may be formed on both sides of the pouch 20, that is, the first package and the second package to confirm the accommodation space S, respectively. The confirmation window 24 is formed to be transparent so that the inside can be visually confirmed. The shape of the check window 24 is not limited as long as the shape of the inside fire extinguishing material 10 can be visually confirmed. The extinguishing material 10 may be released to the outside of the pouch 20 because the extinguishing liquid 10 is naturally vaporized when the use period of the product is elapsed. The confirmation window 24 can identify the extinguishing substance 10, so that it is possible to grasp the replacement time of the extinguishing substance 10.

The confirmation window 24 may be formed to be thinner than other portions of the pouch 20 so that the confirmation window 24 may be rupted before the breakage of the pouch 20 and thus a protective film (not shown) is disposed on one side of the confirmation window 24 . The protective film is attached to the check window 24 so that the breakage strength of the protective film and the check window is equal to or greater than the break strength of the pouch 20 so that the check window 24 ruptures before rupture of the pouch 20 Can be prevented.

4 is a cross-sectional view schematically showing a pouch type fire extinguishing apparatus according to an embodiment.

3 and 4, the pouch 20 is capable of discharging the extinguishing material 10 due to the rupture of the packaging materials 21 and 22, but the outlet 25 for discharging the extinguishing substance 10 To provide directionality when the extinguishing material 10 is released. The discharge port 25 may be formed on at least one side of the pouch 20, that is, on one side of the first packaging material 21 or the second packaging material 22 to release the digestive material 10. For example, the discharge port 25 may be formed such that the rim of the discharge port 25 is thinner than the thickness of the packaging materials 21 and 22. When the extinguishing material 10 is inflated, the rim of the discharge port 25 is first ruptured rather than the rupture of the pouch 20, and the extinguishing material 10 is discharged.

Further, a plurality of outlets 25 may be formed, and it is possible to change the position of the outlets 25 according to the portion to extinguish the fire. The outlet 25 may be formed on the inner surface of the pouch 20 to improve the aesthetics of the pouch 20. The present invention is not limited thereto and the entire portion corresponding to the discharge port 25 may be formed to be thinner than the thickness of the packaging materials 21 and 22 It can be formed thin.

A bonding portion 26 may be formed on the outer surface of the pouch 20. The adhesive portion 26 may be formed on the packaging material 21 or 22 on which the discharge port 25 is formed but the present invention is not limited thereto and the position of the adhesive portion 26 may be changed according to the discharging direction of the extinguishing material 10 . The adhesive portion 26 may be formed by applying an adhesive agent or a double-sided tape or the like so that the pouch 20 may further include a release paper (not shown) for protecting the adhesive portion 26.

The pouch type fire extinguishing device 1 may be installed around an object such as an electric cone center, a switch box, an electric lamp, an electronic product, or a secondary battery. The pouch type fire extinguishing system (1) can be adjusted in thickness according to the degree of accommodating the fire extinguishing material, so that it can be configured in a thinner form than the fire extinguisher, bottle and capsule type fire extinguishing device, It can also be installed between small gaps between different objects.

For example, the pouch type fire extinguisher 1 may be installed between the battery of the portable telephone and the cover. As another example, the pouch type fire extinguishing device 1 may be installed in a gap between the battery of the electric vehicle and the battery. Such a pouch type fire extinguishing system 1 can be disposed between small gaps where bottles, bottles, or capsular fire extinguishing systems can not be disposed, and thus the efficiency of the initial fire suppression can be enhanced.

Hereinafter, a pouch type fire extinguishing apparatus according to another embodiment will be described with reference to FIG. 5 is a perspective view schematically showing a configuration of a pouch type fire extinguishing apparatus according to another embodiment.

Referring to FIG. 5, the pouch type fire extinguisher 2 includes a fire extinguishing material 10 and a pouch 30.

Since the extinguishing material 10 includes the same components as those of the embodiment, its explanation is omitted. The configuration of the pouch 30 excluding the shape retaining portion 31 includes the same constituent elements as those of the embodiment, and a description thereof will be omitted.

The shape retaining portion 31 is provided inside the pouch 30 to maintain the shape of the pouch 30. For example, the shape retaining portion 31 may be formed by bonding the inner surfaces of the pouches 30 to each other at least at one or more positions. The shape retaining portion 31 can support the pouch 30 so that it is not wrinkled or folded. The shape retaining portion 31 may be configured to prevent the pouch type fire extinguishing device 2 from being wrinkled or folded so as to maintain the discharge direction of the fire extinguishing material 10. [

The pouch type fire extinguishing device 3 is provided with a shape retaining part 41 in which at least one is received in the accommodation space S of the pouch 40. At least one of the shape retaining portions 41 is accommodated in the entire accommodating space to maintain the shape of the pouch 40. In other words, one shape retaining part () or a plurality of shape retaining parts (41) are provided in the same shape as the accommodating space (S) to fill the accommodating space (S) to maintain the shape of the pouch (40).

The shape retaining portion 41 is formed with at least one receiving hole 42 for accommodating the extinguishing substance 10. [ The receiving hole 42 accommodates a liquid or solid extinguishing material 10, and isolates each extinguishing material 10. The shape retaining portion 41 may be a porous material that allows only the vaporized digestive material 10 to pass through.

For example, the shape retaining portion 41 may be a melamine sponge material. The melamine sponge is able to penetrate the gas and there is no secondary damage caused by the fire, ie no toxic emissions due to ignition. In addition, the melamine sponge is free from thermal shrinkage.

The liquid extinguishing material may comprise fluorinated ketone and the solid extinguishing material may comprise dry chemical powder.
