Abstract
The utility model relates to a spark plug with an improved side electrode structure. The spark plug comprises a grounding nut, an insulator, a central electrode and a shell, wherein the shell is connected with a side electrode; the side electrode comprises a disc-shaped electrode body arranged above the shell; the electrode body is fixedly connected with the upper end edge surface of the shell by three electrode support legs; and a release space is formed between the electrode body and the electrode support legs. According to the spark plug disclosed by the utility model, the side electrode structure is improved, thus expanding the ignition area of the side electrode; and moreover, spark energy can be effectively transferred into mixed gas, thus improving the heat-conducting performance of the side electrode, and prolonging the service life.
Description
Technical field
The utility model relates to a kind of spark plug.
Background technology
Conventional ignition plug in using both at home and abroad at present, great majority are single central electrode and single-sided electrode structure.The discharge end of this spark-plug side electrode turn of bilge, cover centering electrode top.This spark-plug side electrode is too narrow, to such an extent as to heat conductivility is not fine, after the long-term igniting of spark plug, burning phenomenon easily occurs.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of spark plug that can increase heat conductivility.
The technical scheme in the invention for solving the technical problem is:
The improved spark plug of a kind of side electrode structure, comprise grounding nut, insulator, central electrode and housing, housing is connected with lateral electrode, described lateral electrode comprises the circular electrode body that is arranged on the housing top, electrode body is fixedly connected with the upper end edge face of housing by three electrode legs, between electrode body and electrode leg, be formed with Free up Memory.
As preferably, three electrode leg spaced sets.
As preferably, housing includes upper shell and the lower house that screw thread screws, and described lateral electrode and upper shell integral type arrange.
As preferably, be provided with threaded portion on housing, axially be provided with more than one cleaning groove on threaded portion, described cleaning groove runs through and is arranged on described threaded portion outer surface.
As preferably, clear up groove and be provided with 3.
Lateral electrode is arranged to plate-like centering electrode top, has greatly increased the lateral electrode ignition area, strengthened its heat conductivility, extended useful life.The circular electrode body is fixedly connected with housing by the electrode leg, and forms Free up Memory between the electrode leg, by this Free up Memory, spark energy is delivered in gaseous mixture and goes.
In addition, in use, near easy carbon distribution central electrode and lateral electrode, cleaning is trouble comparatively, and as long as the upper shell that housing is arranged to be threaded and lower house, by upper shell and lower house dismounting, cleared up, more for convenience, extended the useful life of spark plug.Axially run through the cleaning groove is set at the threaded portion of housing outer surface, when screwing in corresponding internal thread, can effectively remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
The beneficial effects of the utility model are: the utility model, by side electrode structure is improved, has strengthened the lateral electrode ignition area, and can effectively spark energy is delivered in gaseous mixture and go, and has strengthened the lateral electrode heat conductivility, has extended useful life.The utility model also is provided with the cleaning groove and housing is arranged to upper-lower casing, easy cleaning dirt and carbon distribution.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the improved spark plug of a kind of side electrode structure, comprise grounding nut 8, insulator 7, central electrode 1 and housing 6, housing 6 is connected with lateral electrode, described lateral electrode comprises the circular electrode body 2 that is arranged on the housing top, electrode body 2 is fixedly connected with the upper end edge face of housing by three electrode legs 3, between electrode body 2 and electrode leg 3, be formed with Free up Memory.Three electrode leg spaced sets.Housing includes upper shell and the lower house that screw thread screws, and lateral electrode and upper shell integral type arrange.Be provided with threaded portion 5 on housing, axially be provided with 3 cleaning grooves 4 on threaded portion, the cleaning groove runs through and is arranged on threaded portion 5 outer surfaces.
Lateral electrode is arranged to plate-like centering electrode 1 top, has greatly increased the lateral electrode ignition area, strengthened its heat conductivility, extended useful life.Circular electrode body 2 is fixedly connected with housing by electrode leg 3, and forms Free up Memory between the electrode leg, by this Free up Memory, spark energy is delivered in gaseous mixture and goes.
In addition, in use, near easy carbon distribution central electrode 1 and lateral electrode, cleaning is trouble comparatively, and as long as the upper shell that housing 6 is arranged to be threaded and lower house, by upper shell and lower house dismounting, cleared up, more for convenience, extended the useful life of spark plug.Axially run through cleaning groove 4 is set at the threaded portion of housing outer surface, when screwing in corresponding internal thread, can effectively remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
The utility model, by side electrode structure is improved, has strengthened the lateral electrode ignition area, and can effectively spark energy is delivered in gaseous mixture and go, and has strengthened the lateral electrode heat conductivility, has extended useful life.The utility model also is provided with the cleaning groove and housing is arranged to upper-lower casing, easy cleaning dirt and carbon distribution.
