Abstract
The utility model relates to a silicon-nitride igniter with an extinguishing protection function, which belongs to the technical field of the ignition of combustible gases. A silicon-nitride ceramic heating component is connected with one end of an insulated ceramic body, a conducting wire connected with the silicon-nitride ceramic heating component penetrates through the insulated ceramic body, the insulated ceramic body is fixedly connected with a mounting flange, another ceramic insulator is also fixedly connected with the mounting flange, a metallic needle penetrates through the ceramic insulators, one end of the metallic needle is arranged in the vicinity of the silicon-nitride ceramic heating component, and the other end of the metallic needle is connected with a signal connecting wire. After the furnace fire is ignited by an ignition head, the conducting wire connected with the heating component can be deenergized, to achieve the effect of saving electricity; when the furnace fire extinguishes, the signal is processed by the metallic needle and then transmitted to the on-off control valve of the combustible gas, and the valve of the combustible gas is closed, or the signal can be transmitted to the micro active switch of the igniter to restart the igniter.
Description
Technical field
The utility model relates to the technical field of structures in the firing technique field, particularly igniter 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.
Existing a kind of silicon nitride igniter, inside is provided with the silicon nitride ceramics heater element, and heater element is connected an end of insulating ceramics, and the two ends of heater element connect lead, and lead passes insulating ceramics.Because what heater element used is resistant to elevated temperatures silicon nitride ceramic material, is provided with electric conductor in the silicon nitride ceramic material, heater element 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, the silicon nitride ceramics heater element is elevated to about 1200 ℃ at 10 seconds internal surface temperatures, utilizes the hot surface of high temperature that fuel gas is lighted.This product stability is good, has reduced the use of electronic devices and components simultaneously, has avoided aging problem, has prolonged service life.But, because the phenomenon that stove fire can occur extinguishing produces the imflammable gas leakage and causes the accident in order to prevent stove fire from extinguishing, people have in use power to igniter all the time, make the silicon nitride ceramics heater element be in fired state, power consumption is big, is unfavorable for conserver power source always.
The utility model content
The purpose of this utility model provide a kind of safe, economize on electricity, the silicon nitride igniter of band extinguish protection function.
The utility model comprises the silicon nitride ceramics heater element, the silicon nitride ceramics heater element is connected an end of insulating ceramics body, the lead that is connected with the silicon nitride ceramics heater element passes the insulating ceramics body, described insulating ceramics body is fixedly connected on the mounting flange, also fixedly connected another ceramics insulator on mounting flange, in described ceramics insulator, place metal needle, an end of metal needle be arranged in the silicon nitride ceramics heater element near, the other end of metal needle connects signal connecting line.
During use, can by mounting flange with the igniter integral installation near burner, metal needle of the present utility model is arranged towards burner, the other end of signal connecting line is connected on the switching control pilot of imflammable gas.After igniter head is lighted stove fire, can be to the lead outage that is connected with heater element.When stove fire occurring and extinguish; thereby by disconnecting owing to air ionization forms closed control circuit between metal needle and the burner; by signal connecting line information is sent to peripheral control unit simultaneously; via controller passes on the switching control pilot of imflammable gas after signal is handled again; close the imflammable gas valve by executing agency, reach the effect of protection.Pass to after perhaps signal being amplified by controller also can microswitch with igniter on, when stove fire extinguished, the microswitch of amplifying signal drive point firearm restarted igniter.
The utility model is simple in structure, convenient to be installed, and high safety can reach the purpose of saving electric energy.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, be provided with silicon nitride ceramics heater element 1 in the igniter, silicon nitride ceramics heater element 1 usefulness high-temp glue is connected an end of insulating ceramics body 3, and the lead 4 that is connected with silicon nitride ceramics heater element 1 passes insulating ceramics body 3 and is connected with external control circuit.
The utility model insulating ceramics body 3 can adopt alumina material to make, and insulating ceramics body 3 is fixedly connected on the mounting flange 2.
Also fixedly connected another ceramics insulator 5 places metal needle 7 in the ceramics insulator 5 on mounting flange 2, and an end of metal needle 7 is arranged in a side of igniter head 1, and the other end of metal needle 7 connects signal connecting line 6.
