Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, specifically a small thermal aerosol fire extinguishing device. Background Technology

[0002] Research on aerosol fire extinguishing technology can be traced back to the 1950s, primarily focusing on fire prevention needs in the military field. With continuous technological advancements, aerosol fire extinguishing technology has gradually been applied to the civilian sector. Early aerosol fire extinguishing devices mainly used the combustion of solid fuels to generate aerosol extinguishing agents, a method that suffered from incomplete combustion, producing large amounts of smoke and harmful gases.

[0003] To address the problems of early aerosol fire extinguishing devices, modern small-scale thermal aerosol fire extinguishing devices employ advanced chemical synthesis and physical dispersion technologies to produce highly efficient, clean, and non-toxic aerosol extinguishing agents. However, aerosol devices typically generate a large amount of heat during the reaction, requiring sufficient strength and heat dissipation. Consequently, current devices are relatively large, bulky, and require significant protective space. Small spaces themselves are inherently confined, with numerous wiring connections, leaving extremely limited space for installing fire extinguishers. Utility Model Content

[0008] Preferably, the lower housing has a mounting hole 1 around its outer perimeter, and the upper housing has a mounting hole 2 around its perimeter. The upper housing can be fixed to the lower housing through the mounting hole 1 on its outer perimeter via the mounting hole 2.

[0009] Preferably, the spray groove has a plurality of spray nozzles, the spray nozzles are located on the top of the upper housing, and the bottom surface of the side wall of the upper housing is flush with the bottom surface of the lower housing.

[0010] Preferably, the openings of the upper and lower wire slots are opposite, and the combination of the upper and lower wire slots forms a wire hole for routing the temperature sensing lead, the electric ignition head, and the signal feedback line.

[0011] Preferably, the inner surface of the side wall of the upper shell and the outer surface of the side wall of the lower shell are coated with an oil-based fireproof and heat-insulating layer.

[0012] Preferably, the upper and lower concave arc structures are arc-shaped, which facilitates the installation of the upper and lower shells.

[0013] Compared with existing technologies, this utility model provides a small-scale thermal aerosol fire extinguishing device with the following advantages: This small-scale thermal aerosol fire extinguishing device adopts a structure with multiple activation methods, which can more effectively and quickly control the fire.

[0018] 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.

[0019] like Figure 1-3 As shown, a small thermal aerosol fire extinguishing device includes a housing 1, which includes a lower housing 101 and an upper housing 2. A thermal aerosol agent 3 is fixedly installed inside the lower housing 101. One end of a temperature sensing lead 6 is provided on one side of the thermal aerosol agent 3. One end of an electric ignition head 5 is fixedly installed inside the thermal aerosol agent 3. A signal feedback line 4 is fixedly installed on one side inside the lower housing 101. A lower wire groove 7 is provided on the left side of the lower housing 101, and an upper wire groove 8 is provided on the left side of the upper housing 2. A lower arc concave 9 is provided on the side of the lower housing 101, and an upper arc concave 10 is provided on the side of the upper housing 2. A spray groove 11 is provided on the top of the upper housing 2, and a nozzle 12 is provided inside the spray groove 11.

[0020] Furthermore, mounting holes 13 are provided around the outer perimeter of the lower housing 101, and mounting holes 14 are provided around the outer perimeter of the upper housing 2. The upper housing 2 can be fixed to the mounting holes 13 on the outer perimeter of the lower housing 101 through the mounting holes 14.

[0021] By using the above technical solution, and fixing the upper and lower housings with mounting holes around their perimeter, the upper housing 2 and the lower housing 101 can be tightly connected at multiple locations. Compared to single-point or a few-point connection methods, this design with mounting holes distributed around the perimeter greatly increases the number of connection points, thereby significantly improving the structural stability of the entire device.

[0022] Furthermore, a number of nozzles 12 are provided in the spray groove 11. The nozzles 12 are located on the top of the upper housing 2, and the bottom surface of the side wall of the upper housing 2 is flush with the bottom surface of the lower housing 101.

[0023] By using the above technical solution, several nozzles 12 are opened in the spray tank 11, which enables the extinguishing agent to be more evenly dispersed into the surrounding space during spraying. When the small thermal aerosol fire extinguishing device is activated, the extinguishing agent is sprayed out simultaneously through multiple nozzles 12, forming a relatively uniform spray coverage area. This avoids the problem of some areas not being effectively covered due to concentrated spraying of the extinguishing agent. The design that the bottom surface of the side wall of the upper shell 2 is flush with the bottom surface of the lower shell 101 helps to improve the stability of the device.

[0024] Furthermore, the openings of the upper wire groove 8 and the lower wire groove 7 are opposite, and the combination of the upper wire groove 8 and the lower wire groove 7 forms a wire hole for the routing of the temperature sensing lead 6, the electric ignition head 5 and the signal feedback line 4.

[0025] Through the above technical solution, the upper wire groove 8 and the lower wire groove 7 are combined to form a wire hole, which can completely wrap the temperature sensing lead 6, the electric ignition head 5 and the signal feedback line 4 inside. This can effectively prevent the line from being directly exposed to the external environment and avoid mechanical damage to the line, such as damage or breakage caused by collision, squeezing or friction from external objects.

[0026] Furthermore, the inner surface of the side wall of the upper shell 2 and the outer surface of the side wall of the lower shell 101 are coated with an oil fireproof and heat-insulating layer.

[0027] Through the above technical solution, when a fire occurs around the small thermal aerosol fire extinguishing device, the fireproof and heat-insulating layer can effectively prevent the flame from directly contacting the shell material. The fireproof and heat-insulating layer has the characteristics of high temperature resistance and can withstand high temperatures without burning or deforming. In the high temperature environment of a fire, it can protect the materials of the upper shell 2 and the lower shell 101 from being directly burned by the flame, and prevent the shell from melting, deforming or burning due to high temperature.

[0028] Furthermore, the upper concave arc 10 and the lower concave arc 9 are arc-shaped, which facilitates the installation of the upper shell 2 and the lower shell 101.

[0029] Through the above technical solution, the upper concave arc 10 and the lower concave arc 9 structure can play a guiding and positioning role during the installation process. When assembling the upper shell 2 and the lower shell 101, the operator can easily and accurately align the upper shell and the lower shell by observing and feeling the correspondence of the arc structure.

[0030] Working principle: First, when a fire is detected by the heat-sensing lead 6, the electric ignition head 5 is activated. At this time, the thermal aerosol agent 3 is activated and sprayed out through the spray channel 11 on the top of the upper shell 2 and the nozzle 12 in the spray channel 11. The fire is extinguished automatically through the signal feedback line 4 and the heat-sensing lead 6.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
