[0025] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0026] In order to facilitate the installation of fire extinguishing equipment in narrow spaces and improve safety performance, Figure 1-Figure 3 As shown, this embodiment provides a flat aerosol fire extinguishing device with a high protection level, comprising an upper cover 1 and a lower cover 2 that are combined to form a hollow cavity, wherein a starting component 3 and a fire extinguishing agent column 4 are sequentially arranged in the hollow cavity from the center to the periphery;

[0027] Among them, the fire extinguishing agent columns 4 are provided in plurality and are arranged at intervals along the circumference of the starting component 3. The starting component 3 is tightly fixed to the center of the hollow cavity by the plurality of fire extinguishing agent columns 4, so that after the starting component 3 is activated, heat can be transferred to the plurality of fire extinguishing agent columns 4, so that the plurality of fire extinguishing agent columns 4 are activated at the same time, thereby improving the fire extinguishing speed.

[0028] In the specific implementation process, according to Figure 1-Figure 3 As shown, the upper cover 1 and the lower cover 2 are fastened together and fixed by the rivet nut 5; in more detail, the lower cover 2 and the upper cover 1 are provided with a plurality of pre-set holes adapted to the rivet nut 5 around them, and the pre-set holes provided on the lower cover 2 and the upper cover 1 are adapted to each other. For easy installation, the upper cover 1 can be provided with a hanging hole (not marked in the figure); the outer wall of the lower cover 1 is provided with a pipe (not marked in the figure) for the trigger line to pass through.

[0029] The side wall of the lower cover 2 is provided with an aerosol spraying nozzle 6 and a sealing strip adapted to the nozzle 6. When the fire extinguishing device is a quadrilateral, the preset hole is arranged near the middle position of the side wall, and the nozzle 6 is located away from the middle position of the side wall to facilitate the formation of the fire extinguishing aerosol to be sprayed into the fire space for fire extinguishing.

[0030] In order to improve the sealing and heat insulation effect of the fire extinguishing device, Figure 1 As shown, the inner walls of the lower cover 2 and the upper cover 1 are provided with an upper silicone pad 7 and a lower silicone pad 8 respectively adapted thereto, so that the starting component 3 and the fire extinguishing agent column 4 are both located between the upper silicone pad 7 and the lower silicone pad 8 and are further compressed.

[0031] In a specific implementation, according to Figure 1 As shown, the starting component 3 includes a starting medicine bag 3a fixed tightly to the fire extinguishing agent column 4, and a combustion-supporting component 3b embedded in the starting medicine bag 3a. The combustion-supporting component 3b is a thermal wire structure or an electric ignition head structure. In this embodiment, when the starting component 3 is a thermal wire structure, it can be automatically started when a fire occurs, and the thermal wire directly ignites the fire extinguishing agent column 4 without the need for additional fire detection devices and other external devices; when the combustion-supporting component 3b is an electric ignition head structure, it is connected to a fire detection device (the fire detection device is a temperature sensor and / or a smoke sensor). When a fire, overheating, etc. occurs, the fire detection device detects that the external high temperature environment is generated by the fire, and sends a signal to the microprocessor, and the microprocessor controls the starting component 3 to ignite the fire extinguishing agent column 4.

[0032] In a specific implementation, according to Figure 2-Figure 3 As shown, the fire extinguishing agent column 4 is a column structure formed by pressing aerosol generating agent powder. The fire extinguishing device can be a cube. In this case, there can be four fire extinguishing agent columns 4, and one fire extinguishing agent column 4 is set on each side of the cube. The four fire extinguishing agent columns 4 are not connected to each other, and the starting component 3 is located in the middle of the four fire extinguishing agent columns 4 to form a cross-shaped structure with the four fire extinguishing agent columns 4. The starting component 3 is located in the middle of the cross to connect the four fire extinguishing agent columns 4, so that after the starting component 3 is turned on, the heat can be quickly and simultaneously transferred to the four fire extinguishing agent columns 4. The four fire extinguishing agent columns 4 are started at the same time. At this time, the generated aerosol is ejected from the gap between the adjacent fire extinguishing agent columns 4, and finally ejected from the nozzle 6 to increase the fire extinguishing speed. In this embodiment, the fire extinguishing agent column 4 can be set to have a thickness of 8 mm and a cross-sectional diameter of 64 mm.

[0033] In a specific implementation, according to Figure 2As shown, a coolant 9 is also provided in the hollow cavity; wherein the coolant 9 is filled in the gap between the edge of the hollow cavity and the fire extinguishing agent column 4, so that the aerosol generated by the reaction after the fire extinguishing agent column 4 is opened is ejected from the gaps between the four fire extinguishing agent columns 4, and after fully reacting with the coolant 9, the flame of the fire extinguishing agent column 4 during the reaction process is isolated, and at the same time, the seal at the nozzle 6 is broken to overflow the fire extinguishing device, and the aerosol floods the protection space, so that the fire inside the space range is extinguished.

[0034] The utility model is achieved in this way:

[0035] The combustion-supporting component 3b opens under the action of the trigger line to ignite the starting medicine bag 3a, and then starts the fire extinguishing agent column 4. At this time, the aerosol generated by the reaction is sprayed out from the gaps between the four fire extinguishing agent columns 4, and after fully reacting with the coolant 9, the flame of the fire extinguishing agent column 4 during the reaction process is isolated, and at the same time, the seal at the nozzle 6 is broken through and overflows from the fire extinguishing device. The aerosol floods the protection space, so that the fire inside the space is extinguished. After the fire extinguishing device is started, except that the surface temperature of the shell in the direction of the nozzle 6 is ≤200°C, no flame spraying phenomenon occurs during the spraying process of the fire extinguishing device.

[0036] In the structure of the utility model, the fire extinguishing agent column 4, the coolant 9, the starting medicine bag 3a and the combustion-supporting member 3b are arranged in a hollow cavity formed by the combination of the upper cover 1 and the lower cover 2, so that the protected fire extinguishing device has a flat appearance, which is convenient for installation in a narrow space and is suitable for starting in complex environments such as high temperature, low temperature, and high humidity without affecting the fire extinguishing performance.

[0037] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0038] Although the preferred embodiments of the utility model have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
