Abstract

The utility model discloses an igniter which comprises a resistor wire, wherein a silicon nitride main body is coated on the outer part of the resistor wire, and the resistor wire leads the silicon nitride main body out and becomes an electrode through a lead; the shape of the silicon nitride main body is cylindrical, the top of the silicon nitride main body is a spherical surface, the bottom surface of the silicon nitride main body is a plane; and an expansion joint is arranged longitudinally at the middle of the silicon nitride main body. The igniter provided by the utility model has the characteristics of long service life and high reliability.

Description

A kind of igniter
Technical field
The utility model relates to a kind of igniter, relates in particular to a kind of liquefied gas igniter.
Background technology
At present liquefied gas igniter is general adopts two metal electrodes, through the liquefied gas that ignites of the discharge between the metal electrode of two vicinities.Because two metal electrodes are exposed in the air all the time, the easy oxidation of surface of metal electrode, service life is short, poor reliability.
Summary of the invention
The technical problem that the utility model will solve: provide a kind of life-span long, the igniter that reliability is high.
The technical solution of the utility model is:
A kind of igniter comprises resistance wire, on resistance wire, is coated with the silicon nitride main body, and resistance wire is drawn the silicon nitride main body through lead becomes electrode.
Said silicon nitride main body be shaped as cylinder, its top is a sphere, the bottom surface is the plane.
As improvement, the central longitudinal that is positioned at the silicon nitride main body is to being provided with the expansion joint.
The technique effect of the utility model is: thus the heat that the energising of the utility model resistance wire produces passes the liquefied gas that ignites through the silicon nitride main body.Because resistance wire is coated with the silicon nitride main body, make resistance wire and air isolated, resistance wire can oxidation by air, is not subject to ectocine yet, and therefore, the utility model igniter life-span is long, the reliability height.The expansion joint is the harmomegathus that causes for the rapid variation that adapts to the silicon nitride body temperature.
Description of drawings
1, Fig. 1 is the utility model igniter front view.
2, Fig. 2 is the utility model igniter upward view.
3, Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
The specific embodiment
Shown in Fig. 1 to 3, a kind of igniter comprises resistance wire 2, on resistance wire 2, is coated with silicon nitride main body 1, and resistance wire 2 is drawn silicon nitride main body 1 through lead becomes electrode 3.Said silicon nitride main body 1 be shaped as cylinder, its top is a sphere, the bottom surface is the plane, the central longitudinal that is positioned at silicon nitride main body 1 is to being provided with expansion joint 4.
The unspecified content of the utility model is prior art, and those skilled in the art can obtain to inspire from present embodiment and prior art, is out of shape to obtain other embodiment.Therefore, the protection domain of the utility model should be confirmed according to the protection domain of claim.
