Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire extinguishing devices, and particularly relates to a non-pressurized self-triggering non-explosive perfluorohexanone fire extinguishing device without external force. Background Art
[0002] The commonly used triggering principles of existing non-pressurized and pressurized fire extinguishing devices are that when the fire extinguishing device needs to be triggered, the preset pressure or the triggering element generates pressure to push the fire extinguishing agent to be released.
[0003] Because the current product design idea is to generate external pressure to release the fire extinguishing agent, the product must have a "pressure chamber" part. At the same time, whether it is pressurized or non-pressurized, the external material of the product needs to have sufficient strength to bear the generated pressure impact.
[0004] Due to the need for external substances to generate pressure to push, in comparison under the same fire extinguishing effect, the existing products have the problems of large product volume, large overall product quality, complex installation, difficult maintenance and replacement, and risks of mis-triggering and non-triggering. Summary of the Utility Model
[0005] Therefore, the embodiment of the utility model provides a non-pressurized self-triggering non-explosive perfluorohexanone fire extinguishing device without external force to solve the above technical problems.
[0006] To achieve the above object, the embodiment of the utility model provides the following technical solutions:
[0007] A non-pressurized self-triggering non-explosive perfluorohexanone fire extinguishing device includes a housing. An inner container is arranged inside the housing, and the inner container is filled with perfluorohexanone fire extinguishing agent. One side of the housing is open, and a mesh outer cover is arranged at the opening as the release area of the fire extinguishing agent. A plurality of release ports are opened on the side of the inner container corresponding to the outer cover to release the fire extinguishing agent.
[0008] Optionally, the side wall of the inner container sequentially includes a plastic sealing layer, a heating layer and an aluminum-plastic layer from inside to outside.
[0009] Optionally, a heating device is arranged inside the heating layer, a sensor is arranged outside the housing, the heating device is provided with a trigger, the trigger is electrically connected to the heating device, and the trigger is electrically connected to the sensor.
[0010] Optionally, the sensor is a smoke sensor.
[0011] Optionally, the sensor is a temperature sensor.
[0012] Optionally, mounting holes are arranged on the housing to mount the housing in a designated fire extinguishing area.
[0013] The utility model has at least the following beneficial effects:
[0014] In the utility model, an inner container is arranged inside the outer shell, and the inner container is filled with perfluoromethylcyclohexanone fire extinguishing agent. According to the physical properties of the perfluoromethylcyclohexanone fire extinguishing agent, when the vaporization temperature is 55°C, the expansion ratio is 1:25. When a fire occurs and the temperature rises, when it reaches 55°C, the perfluoromethylcyclohexanone fire extinguishing agent inside expands, increasing the internal pressure of the inner container. Then, the fire extinguishing agent inside is discharged from the release port and discharged into the air through the mesh outer cover, thus achieving fire extinguishing. No additional pressurizing device is required, which can reduce the volume of the fire extinguisher to a certain extent and facilitate the installation and replacement of the fire extinguishing agent.

[0022] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more. For a solution with a time sequence process, this way of term expression does not have to be understood as describing a specific order or sequence. For a solution of a device structure, this way of term expression also does not distinguish the importance level, positional relationship, etc.
[0024] In addition, the terms "comprising", "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not have to be limited to those steps or units that are clearly listed, but may also include other steps or units that are inherent to these processes, methods, products or devices although not clearly listed, or steps or units added based on further optimized solutions conceived according to the present utility model.
[0025] As Figures 1-3 shown, a non-pressurized self-triggering non-externally-force-exploded perfluorinated hexanone fire extinguishing device disclosed by the present utility model includes a housing 1. An inner container 3 is arranged inside the housing 1. The inner container 3 is filled with perfluorinated hexanone fire extinguishing agent. One side of the housing 1 is open, and a net-shaped outer cover 5 is arranged at the opening as a release area of the fire extinguishing agent. A plurality of release ports 4 are opened on one side of the inner container 3 corresponding to the outer cover 5 for releasing the fire extinguishing agent.
[0026] The above-mentioned inner container 3 is filled with perfluorinated hexanone fire extinguishing agent. The physical properties of perfluorinated hexanone: the vaporization temperature is 55°C, and the expansion ratio is 1:25. Based on these two physical properties, it can be used as a perfect pressure generator by itself and can be released without external pressure.
[0027] One side of the above-mentioned housing 1 is open, which is an open structure, facilitating self-triggering of the fire extinguishing agent. After installation, when a fire occurs and the temperature rises until it reaches the vaporization point of perfluorinated hexanone, the perfluorinated hexanone fire extinguishing agent inside the inner container 3 vaporizes and expands, resulting in an increase in internal pressure, so that the liquid-gas mixture of the fire extinguishing agent can form a mist to provide fire protection for the protected area.
[0028] The side wall of the inner container 3 sequentially includes a plastic sealing layer 31, a heating layer 32 and an aluminum-plastic layer 33 from the inside to the outside.
[0029] A heating device 8 is arranged inside the heating layer 32. A sensor 7 is arranged outside the housing 1. The heating device 8 is provided with a trigger 6. The trigger 6 is electrically connected to the heating device 8, and the trigger 6 is electrically connected to the sensor 7.
[0030] With the above - mentioned setting of the heating device 8, in cooperation with the sensor 7, when the sensor 7 detects a fire, it transmits a control signal to the trigger 6, and through the trigger 6, it controls the heating device 8 inside the inner tank 3 to heat up, so that the perfluorocyclohexanone fire extinguishing agent inside the inner tank 3 is heated to a specified temperature, enabling the perfluorocyclohexanone fire extinguishing agent to be triggered more quickly and improving the fire - extinguishing efficiency.
[0031] The sensor 7 is a smoke sensor 7.
[0032] The sensor 7 is a temperature sensor 7.
[0033] The above - mentioned sensor 7 can be a temperature sensor 7, or a smoke sensor 7, or both can be used in combination to detect whether a fire occurs. According to the detection situation, it judges whether to control the heating device 8 to work and trigger the fire extinguisher in advance.
[0034] The housing 1 is provided with mounting holes 2 for mounting the housing 1 in a specified fire - extinguishing area.
[0035] Multiple connection methods can be adopted at the mounting holes 2 to fix the housing 11 in a specified place, such as by hooks, hinges, etc.
[0036] The advantages of this utility model compared with conventional fire extinguishers are as follows:
[0037] Miniaturization of the fire - extinguishing device (no need for an additional pressurizing device);
[0038] Improved efficiency of fire - extinguishing agent release. Conventionally, it is piston - pressure extrusion, while in this application, the fire - extinguishing agent is directly released by self - generated pressure;
[0039] Avoid non - triggering and utilize the characteristics of the fire - extinguishing agent (vaporization and collision when heated). It will also be triggered autonomously in the case of sensor 7 failure;
[0040] Small overall volume and light weight;
[0041] Convenient installation;
[0042] The main body of the fire - extinguishing device can be reused and is convenient to replace.
[0043] After installation, through the detection device (temperature sensor 7 or smoke sensor 7), it senses the changes in the environment (temperature or smoke). For example, when it senses an abnormal rise in the environmental temperature, it sends a working signal to the heating component inside the device and simultaneously sends an alarm communication signal outside. The heating component quickly generates heat to rapidly increase the environmental temperature of the fire - extinguishing agent. Based on the physical characteristics of the new fire - extinguishing agent, the fire - extinguishing agent expands rapidly when heated and generates a huge pressure, and through the preset release area on the fire - extinguishing agent container, it releases the liquid - gas mixture of the fire - extinguishing agent by self - generated pressure to form a fire - extinguishing protection for the protected area.
[0044] The above several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
[0045] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be regarded as within the scope described in this specification.
[0046] In the foregoing, the present utility model has been described in a relatively specific and detailed manner through general descriptions and specific embodiments. It should be noted that, without departing from the concept of the present utility model, it is obvious that several modifications and improvements can still be made to these specific embodiments, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application shall be subject to the appended claims.
