CN2186459Y - Improved structure of sparking plug terrestrial pole - Google Patents

Abstract

The utility model relates to an improved structure of a sparking plug terrestrial pole. The utility model is composed of a central electrode which is throughout an insulation porcelain body and is exerted, a nut fixed on the upper end of the central electrode, a screw thread body fixed on the bottom end of the insulation porcelain body and a terrestrial pole which extends from the periphery of the screw thread body and is in a bend shape. A throughout groove is arranged on the terrestrial pole; when the high voltage current passes through, the electrode generates ignition; explosive sparks and the groove of the terrestrial pole eject into radial jump spark and are through a combustion chamber which is arranged behind the terrestrial pole; so the utility model can rapidly expand combustion area, complete quickly oil gas vaporizing and completely combust for explosion; the utility model can reduce the accumulation of residual oil, the formation of poisonous gas and air pollution.

Description

Improved structure of sparking plug terrestrial pole

The utility model relates to the igniter of automobile engine.

At present commercially available cigar lighter is by external import, kind is more, pattern is different, but its part structure is identical, by contre electrode (5 '), earth polar (4 '), threaded body (3 '), porcelain body (2 '), nut elements such as (1 ') is formed, key is that the shape and structure in earth polar (4 ') has flat (Fig. 1), have through hole (Fig. 2), have triangle open mouth (Fig. 3), their common defectives are that cigar lighter and vaporized lpg contact area are little, ignition efficient is low, make thoroughly combustion explosion of oil gas, reduced explosive thrust, engine horsepower can't be brought into play, and accumulate Residual oil easily, cause that secondary is surplus quick-fried, noise and air pollution have been increased, cause the reason of above-mentioned defective to be that cigar lighter earth polar and contre electrode (anode) end plate face are all plane and parallel arranged side by side, when high-tension current produces spark (7 ') by contre electrode (5 ') discharge with earth polar (4 '), this spark must be beated to earth polar (4 ') the most nearby by contre electrode (5 ') distal tip place or center, can only burn the oil gas of combustion chamber one side, the oil gas on earth polar lower rear and next door can't be burnt by instantaneous explosion, burning rate is slower, reduced explosive thrust, make engine horsepower can not get performance, and accumulate Residual oil easily, not only can cause secondary surplus quick-fried, increase noise pollution, and because incomplete combustion, the toxic gas volume that produces carbon monoxide and hydrocarbon improves, form air pollution, and acceleration carbon distribution (6 ') speed (seeing Fig. 4-6), it is undesired that its result produces igniting, must often remove and could continue to use, so increase many troubles in the use.

The task of the utility model is to avoid the defective of prior art, and a kind of cigar lighter earth polar of improving structure is provided, and the conflagration blast in order to enlarging burning area reduces the toxic gas discharging, alleviates noise pollution and air pollution.

On the architecture basics that the design of realization the utility model task is to be made of contre electrode (anode), earth polar (negative electrode), nut, porcelain body, threaded body, the earth polar is improved, in the hope of enlarging burning area, acquisition conflagration blast, so the pad-face middle-end is offered the groove of perforation on ground, to eliminate the obstruction that spark that discharge igniting produces is subjected to the ground pad-face, make oil gas at comprehensive explosive combustion of moment, reach and eliminate the surplus quick-fried and air-polluting purpose of secondary.

The improvement structure in this cigar lighter earth polar is brought following advantage: 1. owing to offer the groove of perforation on the earth polar, make spark produce radiation-like and penetrate, strengthened spark intensity, accelerate burning rate, enlarge explosive thrust; 2. increase burning area, make the oil gas burning fully, reduce the waste gas toxic gas and produce; 3. the carbon ash that produces during combustion explosion can be got rid of through earth polar groove radiation-like, reduces coke deposit rate, reduces the trouble of decarbonizing when using; 4. increase the service life.

Be described in detail according to the accompanying drawing embodiment that provides.

The improvement structure in cigar lighter earth polar (referring to Fig. 7-11), comprise that a contre electrode (5 ') is through insulating ceramic (2) and expose, the nut at top (1) is fixed on the upper end of contre electrode, threaded body (3) is fixedly connected on insulating ceramic (2) bottom, it is parallel with contre electrode (5) terminal surface to be bending from the earth polar (4) that the threaded body periphery extends, and form a gap and separate, the groove (6) that (4) plate face middle-end processing one connects on the floor, this groove (6) can be interior narrow outer wide or inner wide and outer narrow shape triangular in shape, or in, wide outward, its both sides of forming groove (6) can be plane or cambered surface.

When central electrode (5) flows into high-tension current via high-tension ignition coil, beat with earth polar (4) generation spark and to the earth polar, the spark (7) that passes groove (8) formation radiation-like penetrates, and has strengthened spark intensity, accelerates burning rate, enlarge explosive thrust and promote the piston rapid movement, and then drive crankshaft rotating and produce revolution inertia force, improved output torque, simultaneously, reduce the generation of toxic gas, reduce air pollution to greatest extent.
