Summary of the invention
It is wider that the utility model purpose provides a kind of spark, and the spark point of generation is many, easier igniting, environmental protection and energy saving, the resistance type multi-ignition spark plug more fully of burning.
The utility model adopts following technical scheme for achieving the above object:
A kind of resistance type multi-ignition spark plug, comprise housing, ceramics insulator, be arranged in central electrode, transition electrode, the wiring screw rod that links to each other with central electrode and the wiring nut of ceramics insulator, the configuration resistance is 3～12K Ω glass fibre resistance between described central electrode and the wiring screw rod, the limit of central electrode extends to outside the housing, when the limit end is arranged on electrion can and transition electrode between produce five jiaos of sheet metals of 2～8 electric sparks, ceramics insulator is arranged in the housing, and the end near transition electrode on the housing is provided with lateral electrode; It is characterized in that above-mentioned lateral electrode) the end several prodgers are set.
Reasonablely be, the transition electrode of stating of the present utility model is " L " shape sheet metal, and several extensions towards five jiaos of sheet metals are set on the transition electrode, and described extension is corresponding mutually with prodger.The height of prodger is 2～6mm.
Reasonablely be, transition electrode of the present utility model is the metal ring of a kind of material in platinum or chromium gold or nickel chromium triangle gold or the yttrium gold, and the thickness of metal ring is 0.8～2mm.
Reasonable is that each angle of five jiaos of sheet metals of the present utility model is projection laterally.
Reasonablely be that the material of five jiaos of sheet metals of the present utility model is a kind of in platinum or chromium gold or nickel chromium triangle gold or the yttrium gold.
