Be provided with piston 9 in the inner chamber at cylindrical shell 1 rear portion, piston 9 can be equipped with O type circle 11 along the moving axially of cylindrical shell 1 on the external circumferential of piston 9, play the sealing function between piston 9 and cylindrical shell 1 inner chamber, prevents that liquid 18 is by piston 9 and reveal from the rear end.Offer axial blind hole 9-1 on the rear end of piston 9, gunpowder 10 is installed in the blind hole 9-1, the rear portion of gunpowder 10 is connected with pyrophoric ignition mechanism 17 and is used to ignite gunpowder 10.Reversal nozzle 12 is installed on the rear end of blind hole 9-1, as shown in the figure, reversal nozzle 12 is the hollow round table structure, and the little bottom surface of round platform is fixedly linked with the rear end of blind hole 9-1 and makes the inner chamber of reversal nozzle 12 be connected with blind hole 9-1, and the big bottom surface of round platform is towards the rear end of cylindrical shell 1.Also be fixed with fixed pedestal 15 in the inner chamber of cylindrical shell 1 rear end, fixed pedestal 15 also is a hollow circular cylinder, the lateral surface of this hollow circular cylinder is fixed on the inwall of cylindrical shell 1 rear end inner chamber, and the front end face of hollow circular cylinder is used to prop up the rear end face of piston 9, in order to avoid piston 9 skids off from the rear end of cylindrical shell 1.In order to adjust to the axial location of piston 9, liquid ejector also includes hollow bolt 16, the inner chamber of fixed pedestal 15 is a secondary shoulder hole structure, the front portion of its close piston 9 is corresponding to the convex step portion, described convex ladder offers female thread structure, the female thread structure of the helicitic texture of hollow bolt 16 and convex ladder is suitable, by rotation hollow bolt 16, the bottom of hollow bolt 16 (end of adjacent piston 9) props up the bottom of piston 9 to adjust the axial location of piston 9.The hollow bolt 16 here is meant the bolt along its axial hollow, because the hollow structure of bolt 16 has guaranteed the space that is provided with of reversal nozzle 12.
Also be provided with over cap 13 on the end face of the rear end of cylindrical shell 1, over cap 13 is by on the end face that is fixed on cylindrical shell 1 rear end that is spirally connected of big blind nut 14 and cylindrical shell 1 rear end.Liquid ejector is not when using, and over cap 13 plays the effect that protection is positioned at the parts of cylindrical shell 1 rear end inner chamber.Over cap 13 adopts rubber or plastic materials, has certain intensity to play a protective role, also have simultaneously certain fragility under the effect of gases at high pressure easily by towards broken.
In addition, below the lateral surface at cylindrical shell 1 middle part, also be fixed with percussion electric supply installation 8, percussion electric supply installation 8 links to each other with pyrophoric ignition mechanism 17 by lead 17-1, operating personnel start pyrophoric ignition mechanism 17 by control percussion electric supply installation 8, pyrophoric ignition mechanism 17 and then ignition gunpowder 10, the blast of gunpowder 10 produces gases at high pressure.
Preferably, equally below the lateral surface at cylindrical shell 1 middle part, be positioned at also to be fixed with on the front end of percussion electric supply installation 8 and be used for the handle 6 that operating personnel hold, operating personnel can a hand-held handle 6, and the another hand is operated percussion electric supply installation 8.Wherein handle 6 can be designed to the folding handle, under non-working condition, handle 6 is folded up, to make things convenient for carrying of liquid ejector.
Further, the top of the lateral surface at cylindrical shell 1 middle part also is fixed with to see takes aim at mirror 7, is used for intended target is carried out the location of liquid when spraying.
The operation principle of liquid ejector of the present invention is as follows:
Operating personnel hold liquid ejector by handle 6, take aim at mirror 7 by sight and find and run-home that pull percussion electric supply installation 8, percussion electric supply installation 8 starts pyrophoric ignition mechanism 17 by lead 17-1, the interior gunpowder 10 of blind hole 9-1 this moment is detonated, and then has produced gases at high pressure.The part promotion piston 9 that the gases at high pressure that produce act on the piston 9 moves forward, liquid 18 in piston 9 and then extruding cylindrical shell 1 and front head 2 inner chambers, the liquid 18 that is extruded breaks through diaphragm seal 4, and the front end mouth of pipe and the rear end mouth of pipe of playpipe 5 of liquid 18 by front head 2 enters in the playpipe 5 and from the front end mouth of pipe high velocity jet of playpipe 5 and go out.According to the law of conservation of momentum, because the injection forward of liquid at high speed, liquid ejector is subjected to corresponding thrust backward, just said recoil in the prior art.But another part of the gases at high pressure that gunpowder produces by reversal nozzle 12 and break through over cap 13 backward high velocity jet go out, according to the law of conservation of momentum, liquid ejector has been subjected to corresponding thrust forward.This part thrust forward can partial equilibrium or the thrust backward (recoil) that is subjected to of complete equipilibrium liquid ejector, makes that this liquid ejector is overall to show less recoil or Recoilless, has greatly reduced operating personnel's operation easier.
