the fire extinguishing agent enters the exhaust box body 22 after being sprayed out of the control valve 6, enters the air spraying plate 8, is discharged through the exhaust hole 11 to extinguish a fire, simultaneously blows the fan blades 23 to rotate through the air flow effect to drive the rotating shaft 24 to rotate, drives the movable plate two 30 to rotate through the rotation of the rotating shaft 24, further drives the movable plate one 29 to rotate, further pushes the sliding rod 27 to slide back and forth in the groove port 26, further drives the push rod 28 to move back and forth, when the push rod 28 moves forward, the piston plate two 32 is pushed to slide forward in the air extracting shell 31, further pushes the air in the air extracting shell 31 to the inside of the ventilation pipe 37 through the check valve two 34, the air entering the inside 37 is guided into the ventilation shell 35, toxic gas generated during the internal combustion of the air is filtered through the filtering function of the filtering net 36, clean air is discharged, when the push rod 28 moves backward, similarly, toxic gas in the container 1 is sucked into the air suction shell 31 through the one-way valve I33 by utilizing the negative pressure effect in the air suction shell 31, so that the reciprocating operation is performed, the air in the container is discharged in time, the fire source is isolated by utilizing the anoxic environment, and meanwhile, the burnt toxic gas is discharged, so that the influence of the toxic gas when workers enter the container 1 is prevented;

when the air is discharged from ventilation unit 3, can blow windward plate 39 and move forward, and then extension spring telescopic link 38, move forward and then promote the upper end of wane 40 and move forward through windward plate 39, because lever principle, the bottom of wane 40 can move to alarm switch 42 direction this moment, because the air of discharging from ventilation unit 3 is discontinuous, consequently alarm switch 42 can constantly be strikeed to the bottom of wane 40, and then realize reminding the staff in succession and inspect inside container body 1, prevent to adopt electronic alarm easily by the high temperature damage when burning, lose the early warning effect, there is certain potential safety hazard.

To sum up, this be applied to combination formula container that aviation loaded, it produces pressure to drive the gasification of the inside evaporated liquid of storage device 5 through the inside temperature variation of container body 1, increase fire extinguishing agent jet-propelled pressure, automatically open control valve 6 simultaneously and jet-blast, drive air exhaust device 10 simultaneously and discharge the inside poison gas of container body 1, utilize the isolated fire source of oxygen deficiency environment, the poison gas after will burning is discharged simultaneously, prevent that the staff from receiving the poison gas influence when getting into container 1, drive alarm device 4 simultaneously and strike alarm switch 42 in succession, and then realize reminding the staff in succession and inspect the container body 1 inside, prevent adopting the high temperature damage when electronic alarm is easily burnt, lose the early warning effect, there is certain potential safety hazard, the structure has linkage nature, degree of automation is higher.

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