Abstract
The utility model relates to an improved spark plug. The improved 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 fan-shaped electrode sheets arranged above the shell; four electrode sheets are arranged and equidistantly arrayed; the inner ends of the four electrode sheets are encircled to form a circular hole; the outer ends of the electrode sheets are fixedly connected to the upper end edge surface of the shell; and the position of the circular hole is corresponding to the central electrode. According to the improved spark plug disclosed by the utility model, the side electrode is formed to be the plurality of fan-shaped structures, thus expanding the ignition area of the side electrode; and moreover, spark energy can be effectively transferred in mixed gas, thus improving the heat-conducting performance of the side electrode, and prolonging the service life. The improved spark plug disclosed by the utility model is further provided with a clearing groove, and the shell is divided into an upper shell and a lower shell, thus facilitating dirt clearing and carbon deposition.
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 of energy increased thermal conductivity energy.
The technical scheme in the invention for solving the technical problem is:
A kind of improved spark plug, comprise grounding nut, insulator, central electrode and housing, housing is connected with lateral electrode, described lateral electrode comprises the sector electrode sheet that is arranged on the housing top, electrode slice is provided with 4 and equidistantly arrangement, the inner of 4 plate electrode sheets surrounds a circular hole, and the outer end of electrode slice is fixedly connected on the upper end edge face of housing, the corresponding central electrode in described circular hole position.
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 upper shell, axially be provided with more than one cleaning groove on threaded portion, the 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 4 fan-shaped electrode slices, is provided with spacing between electrode slice, and the inner of electrode slice surrounds a circular hole, the corresponding central electrode of circular hole position, fan-shaped electrode slice has increased the lateral electrode ignition area greatly, has strengthened its heat conductivility, has extended useful life.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 is by being arranged to lateral electrode the multi-disc sector structure, strengthened the lateral electrode ignition area, and can effectively spark energy be delivered in gaseous mixture and go, strengthen the lateral electrode heat conductivility, extend 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, a kind of improved spark plug, comprise grounding nut 7, insulator 6, central electrode and housing 5, housing 5 is connected with lateral electrode, lateral electrode comprises the sector electrode sheet 2 that is arranged on the housing top, and electrode slice 2 is provided with 4 and equidistantly arrangement, and the inner of 4 plate electrode sheets 2 surrounds a circular hole 1, the outer end of electrode slice is fixedly connected on the upper end edge face of housing, the corresponding central electrode in circular hole 1 position.Housing includes upper shell and the lower house that screw thread screws, and described lateral electrode and upper shell integral type arrange.Be provided with threaded portion 4 on upper shell, axially be provided with the cleaning groove 3 of 3 on threaded portion 4, cleaning groove 3 runs through and is arranged on described threaded portion outer surface.
Lateral electrode is arranged to 4 fan-shaped electrode slices 2, between electrode slice 2, is provided with spacing, and the inner of electrode slice surrounds a circular hole 1, the corresponding central electrode of circular hole 1 position, fan-shaped electrode slice has increased the lateral electrode ignition area greatly, has strengthened its heat conductivility, has extended useful life.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 5 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 3 is set at the threaded portion of housing 4 outer surfaces, 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 lateral electrode being arranged to the multi-disc sector structure, 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.
