Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 This is a schematic diagram of the fire extinguishing device in an embodiment of the present invention.

[0021] The components include: 1. Nozzle; 2. Valve; 3. Pressurized gas; 4. Liquid inlet pipe; 5. Extinguishing agent; and 6. Extinguishing agent storage tank. Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This invention provides a fire extinguishing device that can eliminate fire hazards while avoiding secondary damage to high-end electronic devices caused by the conductivity of the extinguishing agent.

[0025] refer to Figure 1 The fire extinguishing device disclosed in this embodiment includes a fire extinguisher body, a fire extinguishing agent 5, and a pressurized gas 3. The fire extinguisher body includes a fire extinguishing agent storage tank 6, a liquid inlet pipe 4, a valve 2, and a nozzle 1. The nozzle 1 is installed at the top opening of the fire extinguishing agent storage tank 6. One end of the liquid inlet pipe 4 extends to the bottom of the fire extinguishing agent storage tank 6, and the other end is connected to the nozzle 1 through the valve 2. The fire extinguishing agent storage tank 6 contains the fire extinguishing agent 5 and the pressurized gas 3. The fire extinguishing agent 5 is a liquid with insulating properties, and the pressurized gas 3 is a chemically inert gas. After the valve is opened, the fire extinguishing agent 5 with insulating properties is sprayed out by the nozzle 1 under the action of the pressurized gas 3 and covers the fire source, isolating the fire area from the outside air. During the process of covering the fire source to extinguish the fire, because the liquid has insulating properties, the fire extinguishing agent 5 will not become conductive, thereby avoiding the problem of secondary damage to high-end electronic devices caused by conductivity during the fire extinguishing process.

[0026] In this embodiment, the extinguishing agent 5 is a fluorinated liquid, preferably fluorinated liquid 3000D. In addition, those skilled in the art can select mineral transformer oil, natural ester insulating oil or silicone oil and other liquids with insulating properties as needed according to the fire extinguishing requirements. Because the fluorinated liquid extinguishes fires very quickly and leaves no residue, it can also be applied to paper materials or places that are sensitive to water and residue.

[0027] In this embodiment, the pressurizing gas 3 is carbon dioxide. In addition, those skilled in the art can select other chemically inert gases, such as rare gases, as needed.

[0028] In this embodiment, the pressurized gas 3 in the fire extinguishing agent storage tank 6 is located above the fire extinguishing agent 5. After the valve 2 is opened, the fire extinguishing agent 5 flows from the liquid inlet pipe 4 to the nozzle 1 under the action of the pressurized gas 3, and is sprayed outward through the nozzle 1.

[0029] In this embodiment, the fire extinguisher storage tank 6 is made of alloy material to meet the working pressure and prevent leakage.

[0030] In this embodiment, a counterweight is provided at one end of the liquid inlet pipe 4 located in the fire extinguisher storage tank 6. The counterweight pulls the end of the liquid inlet pipe 4 located in the fire extinguisher storage tank 6 so that it is always at the bottom. During use, this ensures that the liquid inlet pipe 4 can guide the fire extinguishing agent 5, thereby improving the performance of the fire extinguisher.

[0031] In this embodiment, the fire extinguishing agent storage tank 6 is equipped with an anti-slip mat on the outside to enhance the stability of the fire extinguisher and prevent it from sliding or tipping over.

[0032] In this embodiment, nozzle 1 is an adjustable nozzle, which is used to change the amount and range of the extinguishing agent, thereby improving the extinguishing efficiency.

[0033] In this embodiment, the fire extinguishing agent storage tank 6 is also equipped with a handle on the outside for easy access and use by operators.

[0034] In this embodiment, a sealing gasket is provided between the nozzle 1 and the extinguishing agent storage tank 6 to improve the internal sealing performance of the fire extinguisher and prevent leakage during the standing period.

[0035] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
