Technical characteristic: gas electronic igniter, it comprises 1.5V dc source, feedback oscillator and electrion mechanism, it is characterized in that:
Feedback oscillator: it is made up of PNP type triode VT1, higher-order of oscillation transformer B, resistance R1, the model that PNP type triode VT1 adopts is 3AX81, PNP type triode VT1 base stage connects the Same Name of Ends of feedback coil L2, the different name end of feedback coil L2 connects the negative pole of 1.5V dc source by resistance R1, PNP type triode VT1 colelctor electrode connects the different name end of primary coil L1, the negative pole of the termination 1.5V dc source of the same name of primary coil L1, PNP type triode VT1 emitter stage connection circuit ground GND;
Electrion mechanism: it is made up of step-up coil L3, electrion tip and kitchen range metal shell, another termination electrion of a termination kitchen range metal shell of step-up coil L3 and circuit ground GND, step-up coil L3 is most advanced and sophisticated;
The positive pole of 1.5V dc source adopts a joint No. 5 alkaline batteries by key switch AN connection circuit ground GND, 1.5V dc source.
Accompanying drawing explanation
Accompanying drawing 1 is the embodiment circuit working schematic diagram that the invention provides a gas electronic igniter, and in accompanying drawing, the pore of primary coil L1, feedback coil L2 side mark is expressed as coil Same Name of Ends.
Detailed description of the invention
According to the gas electronic igniter circuit working schematic diagram shown in accompanying drawing 1 and accompanying drawing explanation, and according to annexation between components and parts in each several part circuit described in summary of the invention, and components and parts technical parameter described in embodiment requires and circuit production main points are carried out enforcement and can be realized the present invention, is further described correlation technique of the present invention below in conjunction with embodiment.
The technical parameter of components and parts and selection requirement
VT1 is PNP type triode, adopts 3AX81 germanium triode, and to improve the drooping characteristic under low-voltage, as used NPN type triode, then pressure drop is comparatively large, and operating efficiency obviously reduces;
The resistance of resistance R1 is 100 ~ 510 Ω, power >=1/4W;
DC adopts a joint No. 5 alkaline batteries.
Circuit production main points and circuit debugging
Because the circuit structure of gas electronic igniter is fairly simple, as long as the electronic devices and components performance generally selected is intact, and the components and parts annexation to specifications in accompanying drawing 1 is welded, physical connection line and welding quality are through carefully checking correctly, and circuit of the present invention does not need to carry out any debugging and can normally work;
The making of higher-order of oscillation transformer B: E type 5 × 7 iron core of the output transformer in available small semiconductor radio, primary coil L1 uses ￠ 0.17mm high strength enamelled wire flat around 30 circles; Feedback coil L2 uses the enamel-covered wire of same wire diameter flat around 60 circles; Step-up coil L3 adopts ￠ 0.06mm high strength enamelled wire around 3500 circles, for effectively preventing coil self high-voltage breakdown, skeleton bursts at the seams altogether groove 10, around enamel-covered wire 350 circle in each wire casing, finally tie up with electrician's adhesive waterproof tape, then seal protection against the tide with 504 epoxy glues or with the leaching of A, B glue;
If oscillating circuit can not starting of oscillation, show as higher-order of oscillation transformer B step-up coil L3 and export without high-voltage pulse, then can the two ends of the two ends of higher-order of oscillation transformer B primary coil L1 or feedback coil L2 be exchanged;
In oscillating circuit, the resistance size of resistance R1 determines the operating current of feedback oscillator, is the operating current of PNP type triode VT1; Require when ensureing that battery electric quantity reduces, under the prerequisite that the circuit of gas electronic igniter still can normally work, the value of resistance R1 should be as far as possible larger, to reduce the operating current of feedback oscillator, extends the service life of battery.
Circuit components layout of the present invention, circuit structure design, its shape and size etc. of outward appearance are not all key technologies of the present invention; because not affecting specific implementation process of the present invention; neither the technology contents of application claims protection, therefore not illustrate one by one in the description.
