[0002] Aerosol is colloquially a small solid or liquid particle dispersed in gas to form a stable state system, and it is a colloidal system with gas (usually air) as dispersion medium and solid or liquid particle as dispersed phase. The aerosol fire extinguishing device contains solid agent, and the components of the agent released by oxidation-reduction reaction are aerosol. The aerosol fire extinguishing device itself generates oxidation-reduction reaction to form a large amount of agglomerated fire-extinguishing aerosol, which mainly consists of N2, a small amount of CO2 and metal salt solid particles.

[0003] The aerosol fire extinguishing device is prone to overheating and flame spewing due to combustion reaction. When the hot aerosol in the aerosol fire extinguishing device reacts, a large amount of gas is generated and ejected to achieve the effect of fire extinguishing. However, the reaction is intense, which can cause the internal pressure of the aerosol fire extinguishing device to be too high. In addition, the internal combustion reaction generates heat, which can cause the aerosol fire extinguishing device to explode, reducing the safety of the aerosol fire extinguishing device. For example, Chinese patent No. CN202020048739.0 discloses a hot aerosol fire extinguishing device. In addition, the aerosol fire extinguishing device is easily affected by electric shock accidents, which can cause the aerosol fire extinguishing device to be mistakenly started and fail to achieve accurate fire extinguishing, resulting in poor user experience.
