Description

Technical Field

[0001] The present invention relates to a high-performance fire extinguishing device, and particularly to a high-efficiency fire extinguishing blanket having a heat-sensitive release structure and a fire extinguishing agent layer. Background Art

[0002] Fire extinguishing blankets are currently widely popular initial fire extinguishing devices. They usually cover the fire source with a flame-retardant material to cut off oxygen and suppress fire spread. Compared with conventional fire extinguishers, fire extinguishing blankets have the advantages of simple operation, convenient portability and are less likely to generate a large amount of residue. Therefore, they are widely used in environments such as home kitchens, industrial sites, electrical equipment and vehicle interior spaces.

[0003] However, while conventional active fire extinguishers (such as dry powder fire extinguishers) have rapid fire extinguishing capability, they have the problems of heavy device weight, high operation threshold, and difficulty in maintaining and managing pressure. In addition, a large amount of dust and fire extinguishing residue are likely to be generated after injection, which may adhere to the surfaces of precision instruments, electronic equipment or valuables to cause secondary pollution, or increase subsequent cleaning and maintenance costs. On the other hand, most conventional passive fire extinguishing blankets only have a physical oxygen blocking function, and mainly reduce the supply of oxygen by covering the fire source. However, when the fire is intense, when the high temperature continues, or in the case of special fires involving oils, alcohols, chemicals, etc., it is often impossible to effectively and quickly reduce the temperature of the fire source, and if the coverage is incomplete, flames may continue to burn through the gaps. Furthermore, some fire sources may cause re-ignition due to continuous internal heat accumulation. Conventional fire extinguishing blankets often lack active fire suppression capability, making it difficult to achieve both fire extinguishing efficiency and use safety.

[0004] In view of this, the present invention proposes a novel high-efficiency fire extinguishing blanket to solve the problems of inconvenient operation and easy occurrence of secondary pollution of conventional fire extinguishers, as well as the problem that conventional fire extinguishing blankets lack active fire suppression capability. [Overview of the project]

[0005] The object of this invention is to provide a highly effective fire extinguishing blanket. The highly effective fire extinguishing blanket has a fire extinguishing agent layer on a flame-resistant layer, and the fire extinguishing material is contained in the fire extinguishing agent layer. When it comes into contact with a fire source, it releases the fire extinguishing material or fire extinguishing substance (gas, liquid, solid, foam, or a combination thereof), simultaneously exhibiting physical oxygen blockage and active flame suppression functions, thereby improving fire extinguishing efficiency and safety of use in initial fires. The fire extinguishing agent layers have independently provided containment spaces. Each heat-sensitive release structure is arranged in a geometric pattern (rectangle, rhombus grid, circle, octagon, or hexagon), allowing for uniform distribution of the fire extinguishing material and expanding the coverage area of ​​the fire source. Furthermore, by providing a breathable structure with micropores in the heat-sensitive release structure, the fire extinguishing substance generated after the fire extinguishing material is heated can be diffused toward the fire source, enhancing the cooling and flame suppression effects. Furthermore, the fire extinguishing agent layer can be provided on only one side of the flame-resistant layer, or on both opposing sides of the flame-resistant layer, allowing for the containment of the same or different types of fire extinguishing materials, thereby increasing the flexibility of the protective arrangement. In addition, the high-performance fire extinguishing blanket can be equipped with color identification marks, text marks, or graphic marks, enabling users to quickly identify sides with different fire extinguishing functions, thereby improving practical usability and operational safety.

[0006] To achieve the above objective, the present invention discloses a high-performance fire extinguishing blanket comprising a flame-resistant layer and at least one fire extinguishing agent layer. The at least one fire extinguishing agent layer is provided on at least one side of the flame-resistant layer. Each fire extinguishing agent layer comprises a heat-sensitive release structure, at least one containment space, and a fire extinguishing material. The at least one containment space is defined by the heat-sensitive release structure. The fire extinguishing material is contained in the at least one containment space. When the heat-sensitive release structure comes into contact with a fire source, the fire extinguishing material, or at least one fire extinguishing substance produced by a heating reaction of the fire extinguishing material, is released from the containment space toward the fire source. The at least one fire extinguishing substance is a gas, liquid, solid, foam, or a combination thereof.

[0007] In an embodiment of the present invention, the heat-sensitive release structure further has a plurality of micropores, and at least one fire-extinguishing substance generated after the fire-extinguishing material is heated diffuses through the micropores.

[0008] In this embodiment of the present invention, the heat-sensitive emission structure ruptures after coming into contact with a fire source.

[0009] In the embodiment of the present invention, the at least one accommodation space is provided independently of each other.

[0010] In the embodiment of the present invention, each heat-emitting structure is arranged in a geometric pattern.

[0011] In the embodiment of the present invention, each heat-sensitive emission structure is arranged in a rectangular, rhombic grid, circular, hexagonal, octagonal, or a combination thereof.

[0012] In the embodiment of the present invention, the fire extinguishing material comprises sodium bicarbonate, ammonium dihydrogen phosphate, potassium carbonate, or potassium bicarbonate.

[0013] In this embodiment of the present invention, the at least one fire extinguishing agent layer is provided on one side of the flame-resistant layer.

[0014] In the embodiment of the present invention, the number of the at least one fire extinguishing agent layer is two, and each of the fire extinguishing agent layers is provided on opposite sides of the flame-resistant layer, and each contains the same or different type of fire extinguishing material.

[0015] In an embodiment of the present invention, the powerful fire extinguishing blanket further includes a color identification mark, a character mark, or a graphic mark.

[0016] In embodiments of the present invention, the heat-sensitive release structure has different thicknesses or a fragile and easily ruptured structure, and acts as a pre-rupture structure to promote the release of fire extinguishing material.

[0017] In an embodiment of the present invention, the heat-sensitive release structure is detachably provided on at least one of the fire extinguishing agent layers.

[0018] In the embodiment of the present invention, the at least one fire extinguishing agent layer completely covers the flame-resistant layer or is concentrated in at least one specific area of ​​the flame-resistant layer.

[0019] In the embodiment of the present invention, the at least one specific region is the central region.

[0022] Hereinafter, the content of the present invention will be described through embodiments. The embodiments of the present invention do not limit that the present invention can only be implemented in any specific environment, application or special method described in the embodiments. Therefore, the description of the embodiments is for the purpose of explaining the present invention, and not for limiting the present invention. It should be noted that, in the following embodiments and drawings, some components not directly related to the present invention are omitted and not shown. In addition, the dimensional relationship between the respective components in the drawings is for the purpose of facilitating understanding, and does not limit the actual proportion.

[0023] Description will be given with reference to FIG. 1 to FIG. 3. FIG. 1 is a schematic diagram showing the action of a high-efficiency fire extinguishing blanket 100 according to an embodiment of the present invention, FIG. 2 is a schematic diagram showing the use state of the high-efficiency fire extinguishing blanket 100 according to an embodiment of the present invention, and FIG. 3 is a schematic diagram showing the structure of the high-efficiency fire extinguishing blanket 100 according to an embodiment of the present invention. In this embodiment, the high-efficiency fire extinguishing blanket 100 comprises a flame-resistant layer 1 and at least one extinguishing agent layer 2. The extinguishing agent layer 2 is provided on at least one side of the flame-resistant layer 1. In this embodiment, the flame-resistant layer 1 is formed of a highly flame-resistant fiber material, for example, formed of glass fiber cloth, flame-retardant fiber cloth or other highly heat-resistant fiber materials. The flame-resistant layer 1 can maintain the structural integrity even under the environment of a high-temperature fire source 200, and can exert the functions of oxygen isolation and fire source containment.

[0024] Further, the fire extinguishing agent layer 2 comprises a heat-sensitive release structure 21, at least one accommodation space 22, and a fire extinguishing material 23. Each accommodation space 22 is defined by the heat-sensitive release structure 21. The fire extinguishing material 23 is accommodated in the accommodation space 22. In this embodiment, the accommodation spaces 22 are provided independently of each other to form a plurality of compartmental storage structures. Thereby, the fire extinguishing material 23 can be uniformly distributed, concentration at one position due to gravity can be prevented, and the covering range for a fire source and the overall fire extinguishing stability can be improved. Further, as shown in FIGS. 3 to 7, each heat-sensitive release structure 21 is arranged in a rectangle, a rhombic lattice shape, a circle, a hexagon or an octagon. In addition, the quantity, size, arrangement positions and arrangement mode of the heat-sensitive release structures 21 of the present invention can all be adjusted according to actual use requirements, and are not limited thereto. The rhombic lattice arrangement is one of the preferred embodiments. The rhombic lattice structure allows the fire extinguishing material 23 to be more uniformly distributed in each accommodation space 22 and prevents excessive concentration of the fire extinguishing material 23, so that the overall fire extinguishing effect and the covering range for a fire source can be improved.

[0025] In this embodiment, the heat-sensitive release structure 21 is formed from a breathable material, such as a nonwoven fabric, a breathable fiber layer, a porous film, or other material having a microporous structure. Among these, a low-melting-point breathable nonwoven fabric is preferred. In one embodiment, the melting point of the heat-sensitive release structure 21 is approximately 110 degrees Celsius or lower, and the instantaneous heat resistance temperature of the flame-resistant layer 1 reaches 1200 degrees Celsius. Therefore, when the heat-sensitive release structure 21 comes into contact with the fire source 200, a reaction occurs preferentially, and the flame-resistant layer 1 can maintain the structural integrity. Furthermore, as shown in Figure 2, the heat-sensitive release structure 21 has a plurality of micropores 211, providing breathability and allowing the fire-extinguishing substance generated by the fire-extinguishing material 23 after heating to pass through. Note that the micropores 211 shown in Figure 2 are schematic, and their shape, dimensions, number, and distribution method can all be adjusted according to actual needs and are not limited to what is shown. Even when the heat-sensitive release structure 21 has not yet ruptured, the fire-extinguishing material 23 generates fire-extinguishing substance through a heating reaction. The fire extinguishing material diffuses toward the fire source 200 through the micropores 211, continuously exerting cooling, oxygen blocking, and flame suppression effects. The at least one fire extinguishing material is a substance formed after the fire extinguishing material 23 is heated, decomposed, melted, volatilized, or chemically reacted, and its state may be gas, liquid, solid, foam, or a combination thereof, but is not limited to a specific state of the substance.

[0026] In another embodiment, when the heat-sensitive release structure 21 comes into direct contact with the fire source 200, the heat-sensitive release structure 21 melts or burns out due to the localized high temperature. As a result, the fire extinguishing material 23 in the containment space 22 comes into direct contact with the fire source 200 and reacts, rapidly generating a large amount of fire extinguishing substance such as fire extinguishing gas. Therefore, the high-performance fire extinguishing blanket 100 can simultaneously have a dual action of explosive release fire extinguishing and gas diffusion fire extinguishing.

[0027] As shown in Figure 1, when the high-performance fire extinguishing blanket 100 covers and comes into contact with the fire source 200, the fire extinguishing material 23 in the fire extinguishing agent layer 2 reacts upon heating, generating fire extinguishing substances such as water vapor and carbon dioxide. The water vapor lowers the temperature of the fire source through endothermic action, and the carbon dioxide lowers the oxygen concentration around the fire source, thereby suppressing the combustion reaction and achieving fire extinguishing effects. In addition, the flame-resistant layer 1 functions as a physical barrier, blocking the supply of oxygen from the outside and containing the fire within the area covered by the high-performance fire extinguishing blanket 100. At the same time, it is possible to reduce the pollution problem caused by the dispersion of the fire extinguishing material 23 into the surrounding environment.

[0028] In this embodiment, the fire extinguishing material 23 includes materials such as sodium bicarbonate, ammonium dihydrogen phosphate, potassium carbonate, or potassium bicarbonate, but the present invention is not limited thereto. In other embodiments, other fire extinguishing materials that can generate an inert gas, an oxygen-blocking gas, or a fire extinguishing substance having a flame-suppressing effect upon heating may be used. For example, the fire extinguishing material 23 can generate carbon dioxide, water vapor, or other flame-suppressing gases upon heating, and can achieve a fire extinguishing effect by reducing the oxygen concentration, absorbing thermal energy, or suppressing the combustion reaction.

[0029] In other embodiments, the number of fire extinguishing agent layers 2 can be two, each provided on opposite sides of the flame-resistant layer 1. Different types of fire extinguishing materials 23 can be contained in each of the opposing fire extinguishing agent layers 2, forming a fire extinguishing structure with different materials on both sides. For example, by placing fire extinguishing material 23 suitable for general fires on one side and fire extinguishing material 23 suitable for electrical equipment fires on the other side, flexibility of use in different fire situations can be increased. Of course, the same type of fire extinguishing material 23 can also be placed in the fire extinguishing agent layers 2 on both sides according to actual needs. Furthermore, the high-performance fire extinguishing blanket 100 can be provided with color identification marks, text marks, or graphic marks to form an identification guide system. This allows the user to quickly and clearly identify sides with different fire extinguishing functions and cover the fire source with the side with the corresponding function according to the type of fire (e.g., Class A, Class B, Class C, or electrical fires). This also reduces the risk of operational errors during emergency use and improves overall usability and safety. In other embodiments, the heat-sensitive release structure 21 is detachably provided on the fire extinguishing agent layer 2, allowing the user to replace it with a different type of fire extinguishing material 23 or replace it after the fire extinguishing material 23 has been consumed. Furthermore, each heat-sensitive release structure 21 is provided independently of the others. Therefore, if some of the heat-sensitive release structures 21 are used, damaged, or contaminated, the user only needs to replace the corresponding area, and there is no need to replace the entire high-performance fire extinguishing blanket 100. This improves the reusability, ease of maintenance, and flexibility in actual application of the high-performance fire extinguishing blanket 100.

[0030] In other embodiments, the opposing heat-sensitive release structures 21 have different thicknesses. This allows for adjustment of the heating reaction rate and the release timing of the fire extinguishing material 23 according to the characteristics of different fire extinguishing materials 23. For example, a thinner heat-sensitive release structure 21 ruptures more quickly upon contact with the fire source 200, while a thicker heat-sensitive release structure 21 delays the release time of the fire extinguishing material 23, thereby improving the overall fire extinguishing effect and safety of use.

[0031] In this embodiment, it is preferable to concentrate the fire extinguishing agent layer 2 in the central region of the flame-resistant layer 1, as shown in Figure 3. At least one fire extinguishing agent layer 2 may selectively cover the entire surface of the flame-resistant layer 1, or it may be provided in a specific region of the flame-resistant layer 1; it is not limited to being concentrated in the central region. This allows the heavy fire extinguishing agent layer 2 to be concentrated and cover the fire source 200 above, improving the active fire extinguishing effect. The areas around the flame-resistant layer 1 where the fire extinguishing agent layer 2 is not provided will naturally sag, completely enveloping the fire source 200 and blocking external air, thus achieving a dual effect of active fire extinguishing and passive oxygen blockage. Furthermore, by concentrating the fire extinguishing agent layer 2 in the central region, the weight of the overall structure can be effectively reduced compared to an arrangement that completely covers the flame-resistant layer 1, achieving the technical benefit of weight reduction. In addition, by concentrating the fire extinguishing material 23 in the center of the fire source, the specific effect of precise fire extinguishing can be achieved.

[0032] In one embodiment, the powerful fire extinguishing blanket 100 is a small fire extinguishing blanket measuring 100cm x 75cm x 0.3cm, with four heat-sensitive release structures 21 provided on one side. In this embodiment, each containment space 22 of the heat-sensitive release structure 21 is filled with approximately 42g of sodium bicarbonate as the fire extinguishing material 23. When sodium bicarbonate is completely decomposed by high temperature, it generates fire extinguishing substances (fire extinguishing gases) such as carbon dioxide and water vapor. Approximately 42g of sodium bicarbonate generates approximately 11L of carbon dioxide, achieving good oxygen blockage and flame suppression effects. Note that the above dimensions, arrangement quantity, and filling weight are merely examples, and this invention can be scaled up or adjusted in the same proportion according to actual application needs, and is not limited thereto.

[0033] In one test example, the powerful fire extinguishing blanket 100 of the present invention was used to extinguish a fire from a Class B ignition source of 70% ethanol fuel. According to the experimental results, the powerful fire extinguishing blanket 100 of the present invention completed the extinguishing of the fire within approximately 15 seconds, and no re-ignition occurred after extinguishing. In contrast, conventional fire extinguishing blankets could not effectively extinguish the fire within 3.5 minutes under the same ignition source conditions, and it was confirmed that the flames only went out after the ethanol fuel had been naturally consumed. This demonstrates that the powerful fire extinguishing blanket 100 of the present invention has a remarkable fire extinguishing effect against ignition sources with high ignition points and high volatility, and that it can significantly reduce the fire extinguishing time.

[0034] As described above, the powerful fire extinguishing blanket of this invention adopts a multi-layer composite structure design and simultaneously possesses a dual fire extinguishing mechanism of "active chemical suppression" and "passive physical blockage" through the arrangement of a flame-resistant layer, a fire extinguishing agent layer, and a heat-sensitive release structure. The flame-resistant layer exhibits functions of oxygen blockage and containment of the fire source. Furthermore, the fire extinguishing material in the fire extinguishing agent layer can release the extinguishing agent or generate fire extinguishing substances after contact with the fire source, thereby achieving the effects of cooling, oxygen blockage, and suppression of combustion reactions. In addition, the partitioned structure by providing each containment space independently of the others, the partitioned structure by arranging each heat-sensitive release structure in a different shape, the arrangement of different materials on both sides, and the detachable and replaceable heat-sensitive release structure give the powerful fire extinguishing blanket of this invention the advantages of rapid fire extinguishing, uniform coverage, ease of operation, reusability, and high flexibility in actual application. This effectively improves upon the problems of conventional fire extinguishing blankets, which only have a passive oxygen blockage function, and conventional fire extinguishers, which are prone to secondary contamination.

[0035] The above embodiments are for illustrative purposes only, illustrating embodiments of the present invention and explaining its technical features, and do not limit the scope of protection of the present invention. Any modifications or equivalent arrangements that can be easily made by a person with ordinary skill in the art to which the present invention pertains fall within the scope claimed by the present invention, and the scope of protection of the present invention shall be based on the claims for utility model registration.
