Description

Technology Field

[0001] The present invention relates to a pouch, and more specifically, to a pouch having a fire extinguishing function that, when a fire occurs in a battery while a battery or an electronic device containing a battery is stored therein, the extinguishing part melts due to the fire and releases an internal extinguishing agent, thereby enabling a response to the initial fire, preventing casualties, and blocking the spread into a large-scale fire at an early stage. Background Technology

[0002] Generally, electronic devices, including batteries, have a problem in that fires can occur due to external impact or internal cracks.

[0003] These electronic devices include portable batteries (including auxiliary batteries for mobile phones) and mobile phones with built-in batteries. Recently, this has become a social issue, such as fires caused by ignition originating from auxiliary batteries on aircraft. Furthermore, in industrial settings, workers frequently wear cooling or heating vests to maintain appropriate body temperatures. Additionally, as the use of portable batteries to power various products increases, awareness regarding the fire risks posed by batteries is rising across diverse fields.

[0004] In addition, mobile phones or portable batteries carried by the general public are also becoming a problem in that they can cause fires in the user's pocket or bag, resulting in burns to the user or posing a fire risk to an unspecified number of people.

[0005] However, most of the components used in these batteries (e.g., lithium) are highly flammable and can actually increase explosive power upon contact with water. Due to the difficulty of extinguishing fires in the early stages, special countermeasures are required; yet, effective measures to address this in advance have not yet been established, and the current response remains passive, amounting to merely warning users to exercise caution on their own.

[0006] Accordingly, there is an urgent need to develop technology that can effectively respond in the early stages to prevent the spread of a fire into a large-scale fire in the event of a fire occurring in a battery inserted in the pockets, pouches, or bags of clothing worn by a user.

[0032] As illustrated in the drawing, the pouch (10) having a fire extinguishing function includes a body (100) and a fire extinguishing part (200).

[0033] The body (100) has a storage space (102) formed inside, which has an entrance / exit opening on one side. The material of the body (100) is preferably fiber glass fabric that can withstand temperatures up to 1650°C.

[0034] And the fire extinguishing unit (200) contains a fire extinguishing agent (212) inside and is installed on the inner side of the entrance of the storage space unit (102).

[0035] The pouch (10) having such a fire extinguishing function according to the present invention stores a battery, and when a fire occurs in the battery while the battery or an electronic device containing the battery is stored, the fire extinguishing part (200) melts due to high temperature and the internal fire extinguishing agent (212) is released, thereby enabling response to the initial fire.

[0036] To this end, preferably, the fire extinguishing part (200) is attached so that the battery is inserted into the storage space (102) as shown in FIG. 2 and is positioned at the connection point with the external connector. This is because the heat-generating part of the battery is mainly the part connected to the connector, and the fire extinguishing part (200) is attached by sewing as a fire extinguishing pad.

[0037] Accordingly, by allowing the fire extinguishing agent (212) attached to the location with the highest risk of ignition at the initial stage of ignition to be released, the spread of fire to the surroundings can be prevented or delayed in advance, thereby preventing the user from suffering burns or the spread into a large fire.

[0038] The body (100) according to the present invention further includes a cover part (110) and a detachable part (120).

[0039] The above cover portion (110) is extended at the upper rear portion to cover the entrance of the storage space portion (102).

[0048] And the fire extinguishing coating (214) is applied to cover the fire extinguishing agent (212), and in the event of a fire, it melts due to the heat from the fire and releases the fire extinguishing agent (212).

[0049] The fire extinguishing coating (214) preferably comprises a first coating layer that surrounds the fire extinguishing agent (212) in a double-coating structure, and a second coating layer that coats the first coating layer.

[0050] The first coating layer may be an organic-inorganic hybrid composition in which nanoparticles of an inorganic material (titanium dioxide, silica, alumina, etc.) are dispersed in a water-soluble polymer matrix (gelatin, chitosan, chitin, carrageenan, etc.).

[0051] The second coating layer may be a polymer resin (e.g., urea formaldehyde, resorcinol formaldehyde) and may be formed through a fluidized bed coating or drying process. In an embodiment of the present invention, the first to second coating layers or the fire extinguishing agent comprises graphite powder or / and copper powder, which provide the effect of blocking the oxygen supply upon ignition by lithium, thereby enabling more efficient initial fire suppression.

[0052] The extinguishing coating layer (220) includes a synthetic resin substrate (e.g., epoxy resin) and a plasticizer, and a extinguishing part (200) in the shape of a extinguishing patch can be obtained by dispersing a extinguishing capsule (210) in the synthetic resin substrate, placing it in a predetermined mold, and molding it.

[0053] The fire extinguishing part (200) in the shape of a fire extinguishing patch obtained as described above is cut into a strip shape and attached horizontally by sewing to the inner side of the entrance of the storage space part (102), preferably to the connector connection part, and, if necessary, can also be attached to the inner side of the cover part, etc. in a predetermined shape.

[0054] With the above configuration, it is possible to suppress the fire at the source of ignition from the initial stage of battery ignition, thereby preventing not only casualties but also the spread into a large-scale fire.
