Description
Technical field
The present invention relates to emitter technical fields, and in particular to a kind of automatic control ignition emitter.
Background technique
Existing shell launcher is in automatic ignition (energization), after shell is launched, on the electrode of launching tube because
Can have on the electrode an oxide generation in the high temperature that one layer of residue of upper covering and ignition point generate after gun propellant combustion, residue and
The accumulation of oxide has gradually formed one layer of nonconducting oxidation film, so that subsequent shell can not emit.Due to actually using
Process excessively in, the transmitting of shell be it is continuous, not allowing before emitting next hair also can be the oxide on electrode without the time
Erasing, connected after causing subsequent shell to be installed it is bad, can not continue to emit.
Summary of the invention
In order to solve existing shell launcher after shell is launched, because propellant powder fires on the electrode of launching tube
Can have on the electrode an oxide generation in the high temperature that one layer of residue of upper covering and ignition point generate after burning, the accumulation of oxide by
One layer of nonconducting oxidation film is gradually formd, so that the problem of subsequent shell can not emit, the present invention provides a kind of automatic control
Igniting emitter.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of automatic control ignition emitter, including interior deck, are equipped with perforative cavity in interior deck, in the cavity
