Abstract
A kind of ring-type automobile spark plug, comprise housing, insulator, grounding nut and central electrode, described housing is connected with lateral electrode, lateral electrode comprises two point lateral electrodes be uprightly arranged on described housing upper surface, two points of lateral electrodes are away from forming the bulge loop coaxially arranged with housing between shell one end, the inner circle of bulge loop is relative with central electrode, bulge loop upwards extends to form a ring-type cambered surface, ring-type cambered surface outer surface inwardly shrinks to away from a point lateral electrode one end gradually by near point lateral electrode one end, ring-type cambered surface inner surface expands outwardly to away from a point lateral electrode one end gradually by near point lateral electrode one end.Its technique effect is: lateral electrode upper end arranges bulge loop and ring-type cambered surface, increases lateral electrode area and do not cover in central electrode, not only can improve ignition effectiveness, avoid flame arrest phenomenon, and can reduce carbon distribution, extending plug useful life.
Description
Technical field
The utility model relates to a kind of spark plug.
Background technology
Conventional ignition plug in using at present both at home and abroad, comprises housing, insulator, grounding nut and central electrode, described housing is connected with lateral electrode, and great majority are the such structures of a central electrode and a lateral electrode.The discharge end of this spark-plug side electrode bend, covers above central electrode, thus covers electric spark, sparking-plug electrode part electric spark is produced to the moment expansion of wink combustion flame, formed and cover and flame arrest effect, weaken electric spark electric heating energy, reduce arcing performance.And after Long-Time Service, the electrode meeting carbon distribution of spark plug, useful life is short, and carbon distribution too much can cause spark plug to scrap, and automobile cannot start.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind ofly to be avoided flame arrest phenomenon and can improve the ring-type automobile spark plug in spark plug useful life.
To achieve these goals, a kind of ring-type automobile spark plug designed by the utility model, comprise housing, insulator, grounding nut and central electrode, described housing is connected with lateral electrode, described lateral electrode comprises two point lateral electrodes be uprightly arranged on described housing upper surface, two points of lateral electrodes are away from forming the bulge loop coaxially arranged with described housing between shell one end, the inner circle of described bulge loop is relative with described central electrode, described bulge loop upwards extends to form a ring-type cambered surface, described ring-type cambered surface outer surface inwardly shrinks to away from described point of lateral electrode one end gradually by near described point of lateral electrode one end, described ring-type cambered surface inner surface expands outwardly to away from described point of lateral electrode one end gradually by near described point of lateral electrode one end.
Preferably, being arranged on described housing upper surface of described two points of lateral electrode symmetries.
Preferably, described housing comprises the upper shell and lower house that are threaded, and described point of lateral electrode, bulge loop, ring-type cambered surface and described upper shell integral type are arranged.
Preferably, described housing is provided with threaded portion, described threaded portion is axially arranged with more than one cleaning groove, and described cleaning groove runs through and is arranged on described threaded portion outer surface.
Bulge loop and ring-type cambered surface are set in a point lateral electrode upper end, add lateral electrode area, improve ignition effectiveness, and owing to defining two through holes between two points of lateral electrodes, this through hole as steam vent, can be conducive to air circulation, spark energy can be made to be delivered in gaseous mixture rapidly and go.Ring-type cambered surface inner surface, by expanding outwardly gradually to away from described point of lateral electrode one end near described point of lateral electrode one end, can reduce the carbon distribution near central electrode and lateral electrode, increase spark plug useful life.
A kind of ring-type automobile spark plug that the utility model obtains, its technique effect is: a point lateral electrode upper end arranges bulge loop and ring-type cambered surface, increase lateral electrode area and do not cover in central electrode, not only ignition effectiveness can be improved, avoid flame arrest phenomenon, and can carbon distribution be reduced, extending plug useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of ring-type automobile spark plug that the utility model provides, comprise housing 1, insulator 2, grounding nut 3 and central electrode 4, described housing 1 is connected with lateral electrode, described lateral electrode comprises two upright and point lateral electrodes 5 be symmetricly set on described housing 1 upper surface, two points of lateral electrodes 5 form the bulge loop 6 that arrange coaxial with described housing 1 away between housing 1 one end, the inner circle of described bulge loop 6 is relative with described central electrode 4, described bulge loop 6 upwards extends to form a ring-type cambered surface 7, described ring-type cambered surface 7 outer surface inwardly shrinks to away from described point of lateral electrode 5 one end gradually by near described point of lateral electrode 5 one end, described ring-type cambered surface 7 inner surface expands outwardly to away from described point of lateral electrode 5 one end gradually by near described point of lateral electrode 5 one end.
Bulge loop 6 and ring-type cambered surface 7 are set in point lateral electrode 5 upper end, add lateral electrode area, improve ignition effectiveness, and owing to defining two through holes 8 between two points of lateral electrodes 5, this through hole 8 can as steam vent, be conducive to air circulation, spark energy can be made to be delivered in gaseous mixture rapidly and go.The inner circle of bulge loop 6 is relative with central electrode 4, does not cover in central electrode, thus avoids flame arrest phenomenon.Ring-type cambered surface 7 inner surface, by expanding outwardly gradually to away from described point of lateral electrode one end near described point of lateral electrode one end, can reduce the carbon distribution near central electrode and lateral electrode, increase spark plug useful life.
In the present embodiment, described housing 1 comprises the upper shell and lower house that are threaded, is conducive to the dismounting of upper shell and lower house, easy cleaning spark plug, the useful life of extending plug.Described point of lateral electrode 5, bulge loop 6, ring-type cambered surface 7 and described upper shell integral type are arranged, and ensure the useful life of spark plug.
In the present embodiment, described housing 1 is provided with threaded portion 9, described threaded portion 9 is axially arranged with more than one cleaning groove 10, described cleaning groove 10 runs through and is arranged on described threaded portion 9 outer surface, when screwing in corresponding internal thread, effectively can remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
