Description

fire extinguisher

[0001] The present invention relates to a container holding a fire extinguishing substance capable of extinguishing a fire, and more specifically, to a fire extinguishing container having a structure in which the material of the container is made of a packaging material with a minimum of three layers and has an outlet capable of holding or leaking the fire extinguishing substance.

[0002] Recently, vehicle fires originating from electric vehicle batteries have been causing frequent social and property damage. In particular, as electric vehicle fires spread rapidly, early suppression is of paramount importance.

[0003] Batteries in electric vehicles or electric motorcycles contain a liquid or solid electrolyte between the positive and negative electrodes. Fires in electric vehicles are often caused by rapid short circuits resulting from external impacts during operation, overcurrent or overcharging, or defects in the battery itself. In most electric vehicles, a monitoring system is designed to issue a warning of high temperature when the battery rises above a set temperature, for example, 60 degrees Celsius.

[0004] Therefore, there is a growing need for devices that prevent or suppress fires by covering, spraying, or flowing a fire extinguishing substance onto the battery when it exceeds a certain temperature.

[0005] The technical problem that the present invention aims to solve is to provide a container containing a fire extinguishing substance that can prevent fires caused by batteries or suppress fires at an early stage.

[0006] In one embodiment of the present invention, a fire extinguishing container is disclosed in which a packaging material is configured to seal a fire extinguishing substance using three or more materials, including an inner layer of synthetic resin, an outer layer of synthetic resin, and a metal intermediate material inserted between the inner layer and the outer layer, and the packaging material is provided with an outlet through which the fire extinguishing substance can be injected or discharged.

[0007] According to one embodiment, the inner layer or the outer layer may be formed by including at least one of polyethylene (PC), polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyvinyl chloride (PVC), MC nylon, polyacetal (POM), polyamide (PA), and Teflon.

[0008] According to one embodiment, the metal intermediate material may be formed in a mesh shape, and the packaging material may be molded into a shape suitable for the top surface shape of the individual battery, such as a flat rectangular pouch or a flat circular pouch.

[0009] According to some embodiments, it may be more preferable that the outlet be formed facing the inside of the packaging material, and the outlet may be formed so as to be sealed with a stopper.

[0010] According to an embodiment of the present invention, if there are signs of a fire occurring in the battery, the fire can be prevented in advance, and even if a fire occurs, it can be suppressed early before thermal runaway occurs.

[0011] The fire extinguishing container according to an embodiment of the present invention can be formed in various shapes, such as a square or a circle, so that it can be seated on the upper surface of an individual battery according to the shape of the individual battery.

[0012] A fire extinguishing container according to an embodiment of the present invention can discharge a fire extinguishing substance by opening the outlet when the stopper detaches and the battery temperature overheats.

[0013] In the fire extinguishing container according to an embodiment of the present invention, when the temperature of the battery is overheated, the fire extinguishing substance can be ejected by tearing between the inner lining and the metal intermediate material constituting the packaging material, or between the outer lining and the metal intermediate material.

[0014] The fire extinguisher container according to an embodiment of the present invention can be manufactured by freely changing its shape, so it can be manufactured to fit the size of the space where the fire extinguisher is to be installed.

[0015] The effects of the present invention are not limited to those described above, and may naturally include effects that are clearly understood by those skilled in the art from the present invention.

[0016] The effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description below.

[0018] FIG. 2 is a drawing showing another embodiment of the present invention.

[0019] Figure 3 is a drawing for explaining packaging materials.

[0020] Fig. 4 shows a fire extinguisher stored in a container.

[0021] In order to fully understand the present invention, the operational advantages of the present invention, and the objectives achieved by the implementation of the present invention, reference should be made to the accompanying drawings describing embodiments of the present invention and the contents described in the accompanying drawings.

[0022] The present invention will be described in detail below by explaining preferred embodiments of the invention with reference to the attached drawings. Identical reference numerals in each drawing indicate identical components.

[0023] In describing the present invention, if it is determined that a detailed description of related known technology may obscure the essence of the present invention, such detailed description is omitted.

[0024] Terms such as first, second, etc., may be used to describe various components, but said components are not limited by said terms, and said terms are used only for the purpose of distinguishing one component from another.

[0025] Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view for explaining one embodiment of the present invention, and FIG. 2 is a perspective view for explaining another embodiment of the present invention. FIG. 3 is a detailed view for explaining the packaging material of the present invention, and FIG. 4 shows a fire extinguisher stored in a container.

[0026] Referring to FIG. 1, the fire extinguishing container (100) of the present invention comprises a packaging material (110), an outlet (130), and a stopper (120). The packaging material may contain a fire extinguishing substance in the form of a liquid, powder, or gas capable of extinguishing a fire. The outlet (130) is formed to contain the fire extinguishing substance inside the packaging material. The stopper (120) serves to prevent the fire extinguishing substance from spilling or flowing out under normal circumstances after the fire extinguishing substance is contained in the fire extinguishing container (100), and allows the fire extinguishing substance inside to be discharged to the outside through the outlet (130) when overheating is detected.

[0027] FIG. 2 is an embodiment showing another form of the fire extinguishing container (200) of the present invention. It should be noted that for convenience, the reference numerals of the detailed components of FIG. 2 are the same as those of FIG. 1, because the functions or roles of these detailed components are identical.

[0028] As can be seen from the shapes of the fire extinguishing containers (100, 200) presented in FIGS. 1 and 2, the shape of the battery is various, such as rectangular or circular, so the shape of the fire extinguishing container can be appropriately modified and manufactured accordingly. Therefore, the fire extinguishing container of the present invention can be appropriately seated on the upper surface of the battery.

[0029] In FIGS. 1 and 2, the outlet (130) and the stopper (120) are shown as being located on the upper surface of the packaging material, but this is merely illustrative and, of course, they can also be located on the side or lower surface of the packaging material.

[0030] In FIG. 4, the fire extinguisher is housed in a container (150) of appropriate size and mounted on the top of the battery, or is designed to facilitate movement and storage.

[0031] FIG. 3 is a drawing for explaining the packaging material of the present invention. The packaging material (110) is preferably composed of at least three layers or a plurality of layers of three or more. In the case of a packaging material (110) composed of three layers, it may be composed of an inner layer (111), an outer layer (113), and a metal intermediate material (115) as shown in FIG. 3.

[0032] Since the inner lining (111) is in contact with the digestive material, it is preferable that the material be one or more combinations of synthetic resins, such as polyethylene (PC), polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyvinyl chloride (PVC), MC nylon, polyacetal (POM), polyamide (PA), and Teflon.

[0033] The material of the outer shell (113) is also preferably one or more combinations of synthetic resins, such as polyethylene (PC), polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyvinyl chloride (PVC), MC nylon, polyacetal (POM), polyamide (PA), and Teflon, just like the inner shell (111).

[0034] The outer shell (113) may have various shapes as needed. For example, the surface may be embossed, or it may have other non-smooth shapes.

[0035] It is preferable that the metal intermediate material (115) be positioned between the inner lining (111) and the outer lining (113). The metal intermediate material (115) allows the housing shape of the fire extinguisher container to be maintained more firmly so that the shape of the inner lining (111) or the outer lining (115), which are made of synthetic resin material, does not get distorted.

[0036] When the packaging material (110) is manufactured in three layers, it is preferable that the metal intermediate material (115) be manufactured by compression or a similar method between the inner layer (111) and the outer layer (115). When the metal intermediate material (115) is positioned between the inner layer (111) and the outer layer (115), there is no direct contact between the metal intermediate material (115) and the fire extinguishing material, so there is an advantage that corrosion of the metal mesh does not occur. In addition, since the metal intermediate material (115) is protected by the outer layer (113), there is an advantage that a short circuit of the metal mesh caused by external electrical leakage can be prevented.

[0037] Hereinafter, one operation in which the fire extinguishing container of the present invention responds to a fire is described. When the temperature of the battery overheats due to abnormal operation of the battery, the temperature of the fire extinguishing container (100, 200) also rises. At this time, the inner lining (111) and the outer lining (113), which are made of a synthetic resin-based material, swell up appropriately, but the thermal expansion of the metal intermediate material (115) does not keep up with this, so the compressed inner lining (111) or outer lining (113) is torn or detached from the metal intermediate material (115). Due to this damage, the fire extinguishing substance in the packaging material (110) is instantaneously sprayed outward or flows out rapidly due to pressure, thereby enabling the fire to be extinguished. The fire extinguishing can be achieved by creating foam from the extinguishing substance that flows out, blocking the inflow of oxygen from the outside, and lowering the temperature of the ignition point through a cooling action.

[0038] In the specification of the present invention, "packaging body damage" means that the inner lining (111) or outer lining (113) is torn or detached from the metal intermediate material (115) due to heat.

[0039] It is preferable that the metal intermediate material (115) be manufactured in the shape of a mesh so that the metal intermediate material (115) can induce damage to the packaging body as the temperature rises. Of course, the specific shape of the mesh can be varied in various ways, such as square, triangle, or circle.

[0040] Another operation of the fire extinguishing container of the present invention in response to a fire is described. When the temperature of the battery overheats due to abnormal operation of the battery, the temperature of the fire extinguishing container (100, 200) also rises. At this time, the volume of the fire extinguishing material also increases due to the heat, and the pressure applied to the packaging material also increases. In response to the increased pressure, the stopper (120) can detach (hereinafter, 'stopper detachment'), and as a result, the fire extinguishing material spills out, allowing the fire to be extinguished.

[0041] The stopper (120) can be fixed by being bonded to the metal intermediate material (115) or by heat fusion. Since the material of the packaging material, the material of the fire extinguishing substance, etc., will have different pressure or volume increase rates due to temperature, the pressure or temperature at which the stopper (120) detaches from the packaging material may also differ.

[0042] The stopper (120) can be fixed by bonding it to the metal intermediate material (115) or by fusion by heat.

[0043] When the degree of overheating of the battery reaches, for example, approximately 60 degrees Celsius, a battery sensing system that detects overheating may send a warning (hereinafter referred to as the 'warning temperature'). Meanwhile, the melting temperature of the inner layer (111) or outer layer (113) of the synthetic resin series varies depending on the material. For example, the melting temperature of polypropylene (PP) material is known to be between 135 and 160 degrees Celsius, and the melting temperature of polyethylene (PE) material is known to be around 137 degrees Celsius.

[0044] If the battery overheats above the melting temperature of the inner casing (111) or the outer casing (113), naturally, the fire extinguishing substance may leak out and the fire may be extinguished due to the melting of the inner casing (111) or the outer casing (113).

[0045] Therefore, it is desirable that the damage to the packaging body or the detachment of the stopper be operated at a temperature between 60 degrees and 130 degrees Celsius. In reality, battery overheating to the point where the inner lining (111) or outer lining (113) melts can already result in a thermal runaway state, spreading to a fire heat of at least 200 degrees to over 1,000 degrees, making it difficult to extinguish the fire even with fire extinguishing agents. Therefore, it is desirable to extinguish the fire early by damaging the packaging body or detaching the stopper, as in the present invention, before reaching a temperature where the inner lining (111) or outer lining (113) melts.

[0046] The present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.
