The utility model relates to an ignition ionization stick for industry nozzle, metal electrode including root length axle form, metal electrode's front end is provided with and is used for the high -pressure electric input end who is connected with high piezoelectric transformer, and the ceramic pipe has been put to last the overlapping of metal electrode, the rear end of ceramic pipe is providedwith the extension metal electrode who is connected with metal electrode. This ignition ionization stick is not only simple structure, has reduced middle the clearance of ignition ionization stick ceramic pipe in addition, avoids influencing the ignition ionization stick ignition position of discharging, improvement ignition success rate and stability because of the foul.
