Secondly, covering and suffocating for fire extinguishing, the perfluorohexanone has high specific gravity and is heavier than air mixture, and oxygen in the air can be isolated for fire extinguishing in the falling process.

And thirdly, chemical inhibition extinguishment, which is based on the principle that decomposition occurs at high temperature, free radicals generated by combustion are captured, and chain reaction causing flame propagation is stopped, so that the development of fire is prevented.

Wherein, information module 5, pressure sensor 6, first fluidic sprinkler subassembly 3 and second fluidic sprinkler subassembly 7 can be installed simultaneously on same fire-fighting equipment, and work step includes like this: when the information module 5 of a fire fighting device detects that the smoke concentration or temperature of the surroundings reaches the first starting condition, judging fire, energizing the electromagnetic control valve 31 close to the fire source to make the first jet nozzle component 3 spray fire extinguishing agent, the rest electromagnetic control valves 31 are locked, the accidental injury range of the fire extinguishing agent is reduced, meanwhile, the rotating component 1 adjusts the angle of the first jet flow nozzle component 3, so that the first jet flow nozzle component 3 sprays the fire extinguishing agent towards the direction of the fire source, meanwhile, all the fire fighting devices are electrically connected through the communication unit of the information module 5, when the electromagnetic control valve 31 of one fire fighting device is started, the other fire fighting devices also start an electromagnetic control valve 31, and the angle of the fire fighting device started after being adjusted by the rotating assembly 1 enables the first jet flow nozzle assembly 3 of the fire fighting device started after being adjusted to spray the fire extinguishing agent towards the fire source direction.

After the first jet nozzle assembly 3 works for a certain time, the information module 5 detects that the smoke concentration or the temperature of the surrounding environment reaches the starting condition of the temperature-sensitive glass bulb 71, at the moment, the information module can judge that the second starting condition is reached, namely, the fire is large, the fire cannot be extinguished timely by only depending on the first jet nozzle assembly 3, or the electromagnetic control valve 31 cannot be started normally, at the moment, the temperature-sensitive glass bulb 71 is broken immediately, the fire extinguishing agent is released to extinguish the fire, and meanwhile, the information module 5 is used for asking for help from a networked fire-fighting system through the communication unit.

When not having the conflagration to take place, detect the pressure in the fire control jar 2 through pressure sensor 6 to communication unit through information module 5 uploads the real-time to networking fire extinguishing systems with pressure sensor 6's detection data, makes the surplus of fire extinguishing agent in the fire control jar 2 can in time be known to the staff, when the pressure in the fire control jar 2 drops to the predetermined value, the staff can be timely through the through-hole of 2 sides of fire control jar, to supplementing fire extinguishing agent in the fire control jar 2.

In the above embodiment, the first nozzle and the second nozzle of the first jet spray head assembly and the second jet spray head assembly are all GG series jet nozzles.
