Igniter composition positioned at front end, shown body 1 is made up of fire-fighting material, and the inside of body 1 is central cavity 2, cylinder afterwards
Body 3, conveyor front barrel 4 are individually fixed in rear end and the front end of body 1, and all communicate with central cavity 2.The quantity of fin 6 is multiple,
Multiple fins 6 are uniformly distributed in the periphery of rear cylinder body 3, be conducive to strengthen shell flight course stability and extend flight away from
From.Explosive 5 is arranged in central cavity 2, after explosive 5 is detonated, for by fire-fighting substance splash in the surface of the object that catches fire,
Fire-retardant to the object that catches fire, to realize fire-fighting fire extinguishing.
It is filled with ignition charge 7, ignition charge 7 is connected with explosive 5 by time delay lead 8 in the end of shown rear cylinder body 3.Push away
Igniter is sent to be made up of base plate 14, connecting plate 15, piston 16, back-moving spring 18, base plate 14 is circle, the number of connecting plate 15
Equal with fin 6 or double, the rear end of connecting plate 15 is fixed on base plate 14, and front end is passed through to connect steel wire 17 and corresponding fin
6 are fixedly connected.Piston 16 is fixed on the central authorities of base plate 14, and corresponding with the internal cavities of rear cylinder body 3, the front end of ignition charge 7
It is provided with dividing plate 20, the central authorities of dividing plate 20 are through hole.When piston 16 moves towards ignition charge 7, due to the stop of dividing plate 20, right
Its generation extrudes and ignites.
Back-moving spring is arranged between base plate 14 and fin 6 or rear cylinder body 3, in the presence of base plate 14 is not subject to ectosome, uses
Remain certain distance it is ensured that explosive 5 is not ignited between guarantee piston 16 and ignition charge 7.Meanwhile, connecting plate 15 and the wing
Connection steel wire 17 before piece 6 plays further safety effect, it is to avoid piston 16 is come in contact with ignition charge 7.In order to ensure
Ignition charge 7 in rear cylinder body 3 is ignited, and piston 16 is offered the air-vent 19 being communicated with the external world, so that ignition charge 7 and the external world
Fuel gas communicates, and is smoothly ignited.
It is provided with igniter, igniter is by ignition charge 7, retainer ring 10, piston 11, arc cap on described conveyor front barrel 4
12 and back-moving spring 13 form, ignition charge 7 be located at conveyor front barrel 4 in, ignition charge 7 is connected with explosive 5 by instant lead 9.Gu
Determine ring 10 to match with the inwall of conveyor front barrel 4 by screw thread, piston 11 is through the internal cavities of retainer ring 10, and direction is ignited
Medicine 7.Arc cap 12 is fixed on the outer end of conveyor front barrel 4, and back-moving spring 13 is arranged between arc cap 12 and retainer ring 10 it is ensured that arc
In the case that shape cap 12 is not contacted with external object, there is a determining deviation with ignition charge 7 in piston 11, will not ignite ignition charge 7.Institute
Insurance locking bolt 21 in piston 11 is provided through on the conveyor front barrel 4 showing, artificially opens when using, more ensure that when not using
Safety.
Fire control shell work process of the present utility model is as follows：Under the thrust of gas in air flue, base plate 14 is forward
Motion, while back-moving spring 18 is compressed, the connection steel wire 17 that connecting plate 15 is mutually fixed with fin 6 disconnects, after piston 16 is incited somebody to action
Ignition charge 7 in cylinder 3 is lighted, and piston 16 produces thrust to dividing plate 20 and base plate 14 to fin 6 and cylinder 3 simultaneously, and here pushes away
Under the collective effect of power and gas, body assembly flies out.Propulsion assembly（14、16、18、15）Separate with body assembly, divide after going out thorax
Other speed falls again respectively.
During fire control shell flies out, time delay lead 8 constantly burns.After fire control shell drops down onto fire area, prolong
When lead 8 burn totally and the explosive 5 that ignites, in the presence of explosive 5, the fire-fighting substance splash in body 1 is come, realizes going out
Fire.Even if time delay lead 8 fails to ignite explosive 5, after the arc cap 12 of body 1 front end is contacted with ground or other objects, lead to
Cross piston 16 ignition charge 7 in conveyor front barrel 4 ignites, and then logical explosive 5 is lighted.
