Abstract
The invention relates to a silicon-nitride igniter, belonging to the technical field of the combustible gas ignition. A heating element is arranged in the igniter head. The igniter head is connected with one end of the insulated ceramic. Both ends of the heating element are connected with wires and the wires pass through the insulated ceramic. The igniter head adopts high-temperature-resistant silicon-nitride ceramic material. The heating element is arranged in the silicon-nitride igniter head. The igniter head is inserted in the upper end of the insulated ceramic and is adhered to the insulated ceramic by high temperature glue. The wires, passing through the insulated ceramic, are connected with the external control circuit. When used, the circuit is switched on, and the surface temperature of the silicon-nitride ceramic material is heated to 1200 DEG C by the heating element within 10 seconds and the high-temperature surface will ignite combustible gas, after that the circuit is switched off and the heating element is power off. The invention has the advantages of good stability, avoidance of ageing and long service life due to less electronic components.
Description
Technical field
The present invention relates to the firing technique field of fuel gas.
Background technology
Use various igniters through regular meeting in the life, the common feature of these igniters is to utilize electronic devices and components to carry out work.A kind of is by piezoelectric ceramics work, and mechanical energy is changed into electric energy, produces electric spark, ignited flammable gas; Another kind is to two electrifying electrodes, produces electric spark between two electrodes, ignited flammable gas.More be to use igniter in occasions such as gas barbecue case, fuel baking oven, dryers to electrifying electrodes, use the igniter of giving electrifying electrodes longer because connect the bar of electrode, aging easily after electronic devices and components work a period of time of these igniters, life-span is short, poor stability.
Summary of the invention
The purpose of this invention is to provide the silicon nitride igniter that a kind of stability is high, the life-span is long.
Be provided with heater element in igniter head of the present invention, igniter head is connected an end of insulating ceramics, and the two ends of heater element connect lead, and lead passes insulating ceramics.
What igniter head of the present invention used is resistant to elevated temperatures silicon nitride ceramic material, in silicon nitride igniter head heater element is housed, and igniter head is plugged on the upper end of insulating ceramics, with high-temp glue they is bonded together.The lead that passes insulating ceramics is connected with the control circuit of outside.During use, connect circuit, heater element was elevated to the silicon nitride ceramic material surface temperature about 1200 ℃ in 10 seconds, utilized the hot surface of high temperature that fuel gas is lighted.Disconnecting circuit after gas is lighted stops heater element being powered.The present invention's stability is high; Because the present invention has reduced the use of electronic devices and components, avoid aging problem simultaneously, prolonged service life.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
As shown in Figure 1, be provided with heater element 2 in igniter head 1, igniter head 1 usefulness high-temp glue is connected an end of insulating ceramics 3, and the two ends of heater element 2 are connected with lead 4 respectively, and lead 4 passes insulating ceramics 3 and is connected with external control circuit.
Claims (1)
1. silicon nitride igniter comprises igniter head, it is characterized in that: be provided with heater element in igniter head, igniter head is connected an end of insulating ceramics, and the two ends of heater element connect lead, and lead passes insulating ceramics.
