According to the fire extinguishing device provided by the utility model, the pushing piece can push the fire extinguishing agent to extinguish fire under the action of the gas generating structure, so that the phenomenon that turbulence is generated due to the fact that the fire extinguishing agent is sprayed out of the nozzle and the space of the storage cavity is vacant is avoided, and the fire extinguishing agent can be sprayed completely is avoided.
When the thrust piece reaches the nozzle, after all the extinguishing agent (usually dry powder) in the extinguishing device is pushed out, the gas generating agent (usually aerosol generating agent) generates high Wen Miehuo material to be sprayed out, and the high temperature of the sprayed gas generating agent possibly causes secondary damage to a protection space.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a piston with a cooling function and a fire extinguishing device thereof, which can avoid secondary damage to a fire extinguishing site caused by high temperature when the piston fire extinguishing device is started.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a take cooling function's piston and extinguishing device thereof, includes protecgulum, casing and the back lid that connects gradually, is equipped with aerosol propellant in back lid department inside, and starting drive gets into from back lid department, and aerosol propellant top is equipped with the piston, and the opposite side of piston is equipped with the extinguishing agent, is equipped with the spout on the protecgulum, and the piston is cavity structure and both ends have the hole and inside to be equipped with cooling structure.
The cooling structure comprises the following components:
the piston comprises a piston shell, a cooling medium is arranged in the piston shell, a piston nozzle is arranged on one side, close to the extinguishing agent, of the piston shell, a piston cover plate is arranged on one side, close to the aerosol generating agent, of the piston shell, and a hole is formed in the piston cover plate.
