[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Reference Figure 1 to Figure 2 and Figure 4According to an embodiment of the first aspect of the utility model, an automatic fire extinguishing device includes a shell 100 and a fire extinguishing core 200. The shell 100 has a housing chamber 110. An output port 120 is provided on one side wall of the shell 100. The output port 120 is communicated with the housing chamber 110. The fire extinguishing core 200 is arranged in the housing chamber 110. The fire extinguishing core 200 has a jet port 210. The jet port 210 is arranged toward a side away from the output port 120. The jet port 210 is arranged opposite to the output port 120, so that when the jet port 210 of the fire extinguishing core 200 jets gas, the gas will first be jetted to the inner wall of the shell 100 on the other side of the output port 120, and then flow through the housing chamber 110 to the output port 120 in the opposite direction for output, which can extend the flow distance of the gas, and the gas flow needs to change direction, so that sparks and waste residues can be blocked in the housing chamber 110 to a large extent. Through the above structure, the overall structure can be simplified under the premise of blocking sparks and waste residues, and the manufacturing cost is low.

[0031] Specifically, the shell 100 has a accommodating cavity 110 inside, and the fire extinguishing core 200 can be placed in the accommodating cavity 110, and there is a certain gap between the fire extinguishing core 200 and the shell 100 for gas flow, and the fire extinguishing core 200 can be provided with a corresponding trigger structure, and the trigger structure can be set as a temperature sensing line, one end of the temperature sensing line can be connected to the fire extinguishing agent, and the other end can be set outside the shell 100. When the external temperature sensing line senses the external temperature ≥±170°C, it can automatically start to ignite the fire extinguishing core to release the fire extinguishing mist for full flooding fire extinguishing. A nozzle 210 is provided on one side of the fire extinguishing core 200, and the nozzle 210 can be set as a plurality of through holes arranged at intervals, and the shell opposite to the nozzle 210 is provided with a nozzle 210. An output port 120 is provided on the body 100, and the output port 120 can also be set as a plurality of through holes. After the fire extinguishing core 200 is triggered, the combustion reaction will spray gas, and the gas and waste residue will be ejected from the injection port 210, and guided to flow in the accommodating cavity 110 of the shell 100 to the output port 120 for injection, thereby realizing the injection gas fire extinguishing. Through the above structure, only one layer of shell 100 needs to be set, and the structure is simple. Since the injection direction of the fire extinguishing core 200 is opposite to the setting direction of the output port 120, the gas cannot be directly output, but needs to reflux in the accommodating cavity 110, so that the sparks and waste residue are trapped in the accommodating cavity 110 to a certain extent, thereby meeting the use requirements, and the structure is simpler and the manufacturing cost is low. It is understandable that the reactants inside the fire extinguishing core 200 can be made of 43% high-purity (99.9%) food-grade potassium nitrate, 32% dicyandiamide and 25% natural resin glue (without strontium nitrate) as raw materials, which can be stored in a solid state without pressure at -60°C to +160°C, and can be ignited when encountering an open flame, or started at a high temperature of more than 400°C, and self-carrying oxygen combustion. The gas fire extinguishing core sprays potassium ions (K) in the aerosol to make it join the oxygen ions (O), hydroxide (0H) and hydrogen ions (H) in the flame chain carrier to react, and the potassium ion (K) ion free radicals attach oxygen ions (O), hydroxide (0H) and hydrogen ions (H) to remove them from the flame without consuming the surrounding oxygen, thereby suppressing the flame and ensuring the safety of personnel.

[0032] It can be understood that the fire extinguishing core 200 has a cavity inside, and a filter can be arranged between the reactant and the injection port 210. The filter can initially filter impurities in the injection gas and further block the impurities from being ejected.

[0033] Reference Figures 1 to 3 In some embodiments of the present invention, the shell 100 includes a bottom shell 130 and a cover body 140. The bottom shell 130 is provided with a receiving groove. The cover body 140 is detachably connected to the bottom shell 130, and the cover body 140 can cover the opening of the receiving groove of the bottom shell 130 to form a receiving cavity 110. The overall assembly of the shell 100 is simple.

[0034] Specifically, the bottom shell 130 can be square in shape, with the receiving groove opening set upward, and the cover body 140 can be detachably installed on the top of the bottom shell 130 to cover the receiving groove to form the receiving cavity 110. During assembly, the fire extinguishing core 200 can be placed in the receiving groove, and then the cover body 140 can be installed, which is simple to assemble.

[0035] Reference Figure 2 In some embodiments of the present invention, the cover 140 is provided with a first clamping portion 141, and the bottom shell 130 is provided with a second clamping portion 131, and the first clamping portion 141 can be clamped with the second clamping portion 131. The assembly is convenient.

[0036] Specifically, the bottom of the cover 140 may be provided with a plurality of first clamping parts 141, and the bottom shell 130 may be provided with a corresponding second clamping part 131, the first clamping part 141 may be provided as a clamping slot, and the second clamping part 131 may be provided as a buckle, and during installation, the cover 140 may be directly clamped on the bottom shell 130, and the clamping slot and the buckle may be clamped together, which is convenient for assembly. It is understandable that the cover 140 may also be provided with a buckle, and the bottom shell 130 may be provided with a corresponding clamping slot.

[0037] It should be noted that the connection structure between the cover body 140 and the bottom shell 130 is not limited to the above embodiments, and can also be set to other embodiments. For example, the cover body 140 and the bottom shell 130 can be connected by fasteners, or the cover body 140 and the bottom shell 130 can be connected by a threaded structure.

[0038] Reference Figure 5 It should be noted that the housing 100 can be installed in the applied component by bonding or fastener connection. 3M glue can be provided on the outer surface of the cover 140 so that it can be connected by glue, which is convenient for installation. Alternatively, horizontal mounting grooves 142 can be provided on both sides of the cover 140, and mounting sliders 143 are provided correspondingly. The mounting sliders 143 are provided with long strip-shaped mounting holes 1431. It can be understood that the mounting grooves 142 can be provided with limit columns, and the limit columns cooperate with the mounting holes 1431 so that the mounting sliders 143 can slide within a certain range. After sliding outward, the mounting holes 1431 are exposed. Bolts can be used to connect the applied component through the mounting holes 1431, and the mounting holes 1431 can be slid to adjust the position to adapt to different installation positions. When bonding is used, the mounting sliders 143 can be slid inward to retract the mounting holes 1431.

[0039] Reference Figure 3 In some embodiments of the present invention, the bottom wall of the receiving groove is provided with a limiting portion 132, and the fire extinguishing core 200 can cooperate with the limiting portion 132 to limit the lateral movement of the fire extinguishing core 200. The fire extinguishing core 200 can be roughly fixed to meet the use requirements.

[0040] Specifically, the fire extinguishing core 200 can be cylindrical, and the limiting portion 132 can be set to four limiting blocks. The limiting blocks can be correspondingly arranged at the four corners of the fire extinguishing core 200. The limiting blocks can be provided with limiting grooves matching the shape of the fire extinguishing core 200. The fire extinguishing core 200 can be placed on the limiting grooves, and the lateral movement of the fire extinguishing core 200 can be limited by the limiting blocks.

[0041] Reference Figure 2 and Figure 4 In some embodiments of the present invention, a first insulation component 300 is further included, and the first insulation component 300 is disposed in the accommodating cavity 110, and the first insulation component 300 is located between the injection port 210 and the side wall of the shell 100. The heat insulation effect can be improved, so that the shell 100 will not be overheated, avoiding other accidents.

[0042] Specifically, the first thermal insulation component 300 can be arranged on the side wall of the shell 100 and on the side wall opposite to the injection port 210. The gas ejected from the injection port 210 by the fire extinguishing core 200 has a higher temperature at the beginning. Therefore, allowing the gas to contact with the first thermal insulation component 300 first can effectively insulate the temperature, so that the shell 100 will not overheat and cause other flammable objects to burn.

[0043] It is understandable that the housing 100 may also be directly made of a temperature-insulating material, or a temperature-insulating cavity may be provided inside the housing 100 .

[0044] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the first insulation component 300 is plate-shaped and slidably disposed on the housing 100. The assembly is convenient and the manufacturing cost is low.

[0045] Specifically, the first thermal insulation component 300 is in the shape of a plate, and its specific material structure is not specifically limited. The first thermal insulation component 300 can be slidably inserted into the shell 100. It can be understood that the shell 100 can open the accommodating cavity 110. During assembly, the first thermal insulation component 300 can be slidably inserted from the opening of the opened accommodating cavity 110, which is convenient to assemble and has low manufacturing cost.

[0046] Reference Figure 2 and Figure 3 In some embodiments of the present invention, a slide groove 150 is provided on the inner wall of the housing 100, and the first insulation component 300 can be slidably connected with the slide groove 150. This can facilitate the positioning and assembly of the first insulation component 300.

[0047] Specifically, slide grooves 150 may be provided on two opposite inner side walls of the housing 100 so that the plate-shaped first thermal insulation component 300 can be slidably installed along the slide grooves 150 to facilitate positioning and assembly.

[0048] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the first thermal insulation component 300 includes a first thermal insulation sheet 310 and a mica sheet 320. The first thermal insulation sheet 310 and the mica sheet 320 are arranged in close contact with each other, and the first thermal insulation sheet 310 is arranged close to the fire extinguishing core 200. The thermal insulation effect can be further improved.

[0049] Specifically, the first thermal insulation sheet 310 can be an insulating iron sheet that can withstand high temperatures and gas impact, while the mica sheet 320 can provide a good thermal insulation effect. By fitting the two sheets together, the first thermal insulation sheet 310 is arranged in the accommodating cavity 110. It has high structural strength, high temperature resistance, and can withstand gas impact, while the mica sheet 320 can provide heat insulation, which can further improve the thermal insulation effect.

[0050] Reference Figure 2 and Figure 4 In some embodiments of the present invention, a second insulation component 400 is further included. The side wall of the housing 100 provided with the output port 120 is provided with the second insulation component 400, and the second insulation component 400 is located in the accommodating cavity 110. The insulation effect can be further improved.

[0051] Specifically, the second thermal insulation component 400 can be arranged on the side wall of the shell 100 having the output port 120, and is arranged opposite to the first thermal insulation component 300. When the gas flows out of the output port 120, the heat will gather on this side wall. The first thermal insulation component 300 can isolate the heat well, so that the shell 100 will not overheat, and the thermal insulation effect can be further improved.

[0052] Reference Figure 4 In some embodiments of the present invention, the second thermal insulation assembly 400 includes a second thermal insulation sheet 410, the second thermal insulation sheet 410 is provided with a communication port 411 corresponding to the output port 120, and the second thermal insulation sheet 410 is slidably disposed on the housing 100. The temperature of the housing 100 can be further reduced, and the assembly is convenient.

[0053] Specifically, the second thermal insulation sheet 410 can be a thermal insulation iron sheet, and a corresponding connecting port 411 is arranged on the second thermal insulation sheet 410, and the connecting port 411 is connected to the output port 120, and the aperture of the connecting port 411 can be set to be smaller than the aperture of the output port 120, so that when the gas is ejected outward, a negative pressure is formed at the output port 120 to replenish the external air, thereby being able to cool the shell 100 to further reduce the temperature of the shell 100, and a corresponding sliding structure can be arranged on the inner wall of the shell 100 for the second thermal insulation iron sheet to be slidably connected, so as to facilitate the assembly of the second thermal insulation iron sheet.
