By using above-mentioned technical proposal, taper air gun nozzle reduces projected area, and fuel is ejected so as to increase
Spouting velocity so that fuel energy more concentrate by injector, and fuel spouting velocity drives the row of gas compared with conference
Go out, so that air pressure reduces in air hose, outside air is constantly by air admission hole air inlet pipe.
Further set：Flame detector is also equipped with the air hose, the flame detector includes ion probe,
The ion probe is located at the outgassing direction of air hose.
By using above-mentioned technical proposal, flame detector can detect to the flame of ignition air gun, avoid burning
Fuel is not burned and is dispersed into environment in rifle, causes danger.
Further set：The air hose includes body and end cap, and the burning torch and fuel gun are located at end cap.
By using above-mentioned technical proposal, air hose split settings are split when needed, convenient maintenance and peace
Dress.
Further set：Offer the fire hole for leading to air hose on the end cap, the fire hole be divided into screwed hole and
Diameter penetrates hole equal to burning torch diameter, and seal nipple is fixedly connected with the burning torch.
By using above-mentioned technical proposal, burning torch is detachably connected on end cap, when needing repairing, by burning torch
Seal nipple back-out from fire hole, to burning torch carry out inspection and maintenance, it is necessary in use, burning torch be penetrated into igniting
Hole, and seal nipple and fire hole screw thread are coordinated, complete assembling.Convenient disassembly, maintenance and the efficiency changed are improved, it is convenient
Use.
In summary, the utility model has the advantages that：
1st, by the setting of injector, reduce the setting of form of compressed air injection structure, simplify air gun structure, reduce
Cost during making；
2nd, it is provided with the flame that flame detector sprays ignition air gun to detect, timely alarm, is carried when breaking down
High security.
