When a fire occurs in the protection space, the fire signal is detected by the electric initiator arranged in the protection space, and the electric initiator promptly sends the electric start signal to the electric start line 10 and the feedback signal line 11. The electric start line 10 and the feedback signal line 11 receive the electric start signal to activate the aerosol generator 9 for fire extinguishing. When a fire occurs, the open flame generated by the fire can also ignite the thermistor 12. After the thermistor 12 is ignited, the aerosol generator 9 can also be activated. By activating the aerosol generator 9 in two ways, the fire can be automatically extinguished in time, the response speed is fast, and the loss can be minimized. When the aerosol generator 9 is activated, the heat released by the oxidation-reduction reaction of the aerosol generator 9 is released through the The third air vent 84 of the connecting box 8 is transported to the placement hole 32 of the placement block 3, and is transported to the refrigerant 4 through the first connecting hole 33 and the second connecting hole 34, so that the refrigerant 4 is decomposed, so that the aerosol generator 9 and the refrigerant 4 jointly participate in fire extinguishing. The aerosol generator 9 is used to extinguish the fire. On the one hand, there is the cooling effect of the endothermic decomposition of the aerosol generator 9, and on the other hand, there is the chemical inhibition effect of the gas phase and the solid phase, which work synergistically with each other. In addition, the gas phase component in the product of the redox reaction of the aerosol generator 9 also plays a certain auxiliary role. The product of the reaction of the aerosol generator 9 and the substance after the decomposition of the refrigerant 4 enter the accommodating cavity 131 of the end cover 13 through the first air vent 62 and the second air vent 72, and are finally discharged through the air outlet 133 to extinguish the fire area. The fire prevention response is fast and the fire extinguishing efficiency is high. Moreover, the device is small in size, stored at normal pressure, and does not require the laying of a pipeline network; the fire extinguishing speed is fast and there is no dead angle; it is non-toxic, non-corrosive, and does not damage the atmospheric ozone layer.

[0128] (1) Under the action of heat, the gasified metal ions such as Sr, K, Mg or cations that have lost electrons decomposed by the hot aerosol fire extinguishing agent (electrical automatic fire extinguishing device) exist in the form of steam and undergo multiple chain reactions with the active groups H•, •OH and O• in the combustion. The following takes Sr as an example:

[0129] Sr+2•OH→Sr(OH)2 Sr+O•→SrO Sr(OH)2+2H•→Sr+2H2O

[0130] This process is repeated many times, and the active groups in combustion are consumed in large quantities, the concentration continues to decrease, and combustion is suppressed.

[0131] (2) The solid particles in the hot aerosol fire extinguishing agent (electrical automatic fire extinguishing device) can absorb the chain reaction intermediates •OH, H• and O•, and catalyze them to re-form stable molecules, thereby interrupting the branch chain reaction of the combustion process.

[0132] Let's take K as an example:

[0133] K2O(s)+2H(g)→2KOH(s) KOH(s)+OH(g)→KO(s)+H2O(g)

[0134] K2O(s)+O(g)→2KO(s) KO(s)+H(g)→KOH

[0135] In the above-mentioned fire extinguishing effect, several fire extinguishing mechanisms interact and work synergistically, but the gas transmission effect and the heat absorption and cooling effect of metal oxides or carbonates only play auxiliary effects, and the main fire extinguishing effect still relies on the chemical inhibition of gas and solid phases.

[0136] When a fire occurs, after the fire extinguishing device receives an electric start signal or an open flame ignites the thermistor, the electric initiator or thermistor burns and activates the aerosol generator in the fire extinguishing device. The heat released by the aerosol generator through the redox reaction decomposes the chemical coolant, allowing the aerosol generator and the coolant to jointly participate in fire extinguishing.

[0139] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
