Abstract
The utility model relates to an electronic ignition device of a lighter, which is provided with a self-excited oscillation circuit and a transformer. The electronic ignition device of a lighter adopts a photoelectric transducer with high sensitivity, and uses a weak natural light source as a signal source to open the oscillation circuit (igniting). The electronic ignition device of a lighter accomplishes components domestically produced by a combining voltage stabilizing circuit, and the photoelectric transducer D1 is connected between the base of a triode T and the primary coil of the transformer L and a capacitor C. One head of an electric inductor L3 is connected between the capacitor C and the combining voltage stabilizing circuit by a diode D2.
Description
The utility model relates to a kind of electronic ignition device that is used for lighter.
At present both at home and abroad comparatively advanced full-automatic electronic lighter has touch-switch type, light induction type etc., and wherein touch-switch type major defect is to have contact switch, and the contact is tired easily and damage short, poor reliability of life-span; The easy variate of inductance in light induction type electricity loop causes the starting of oscillation shakiness, and reliability is also relatively poor.And above-mentioned two kinds of machines all need be provided with the luminous tube indicator lamp, make circuit power consumption excessive, reduce the service life of battery, and also existing often needs repeatedly to start the possibility that could light a fire.
The purpose of this utility model be to overcome above-mentioned technology defective, provide that a kind of use is more easy, the electronic ignition device of ignition performance is reliable, power consumption economizes, the life-span is long lighter.
The utlity model has self-maintained circuit and transformer L, self-maintained circuit is by triode T, inductance L 1, L2, L3 and resistance R constitute, the ground level of triode T and inductance L 1, L2, L3 is connected in series successively, emitter-base bandgap grading is connected between L2 and the L3, colelctor electrode connects power cathode, connect positive source between inductance L 1 and the L2, the primary coil of transformer L and capacitor C, the combination mu balanced circuit is connected in series successively and constitutes the loop, connects between the primary coil of the base stage of triode T and the L of transformer and the capacitor C and establishes photoelectric transformer D1,3 one of inductance L are received between capacitor C and the combination mu balanced circuit through diode D2.
Further content of the present utility model is provided by following examples and accompanying drawing.
Accompanying drawing is the line assumption diagram of present embodiment.
Present embodiment has self-maintained circuit and transformer L, self-maintained circuit is by triode T, inductance L 1, L2, L3 and resistance R constitute, the base stage of triode T and inductance L 1, L2, L3 is connected in series successively, emitter-base bandgap grading is connected between L2 and the L3, colelctor electrode connects power cathode, connect positive source between inductance L 1 and the L2, the primary coil of transformer L and capacitor C, the combination mu balanced circuit is connected in series successively and constitutes the loop, connects between the primary coil of the base stage of triode T and transformer L and the capacitor C and establishes photoelectric transformer D1,3 one of inductance L are received between capacitor C and the combination mu balanced circuit through diode D2.The combination mu balanced circuit is made up of a trigger tube SCR and two voltage-stabiliser tube Dz1, Dz2 arranged side by side, wherein the trigger electrode of the termination trigger tube SCR of voltage-stabiliser tube Dz1.
After present embodiment is installed and used, utilize the folding control photoelectric transformer D1 of sparking cover, cover is opened, photoelectric transformer D1 sees light: internal resistance reduces electric current and increases, the pressure drop of this electric current on resistance R raises, thereby make the current potential of triode T base stage descend turn-on transistor T, self-maintained circuit starting of oscillation, oscillating voltage is exported through diode D2, trigger and conducting combination mu balanced circuit, because the saturated charging of capacitor C this moment, in case the conducting of combination mu balanced circuit, then capacitor C discharge, the secondary coil of transformer L induces high voltage pulse, reaches the igniting purpose, and the effect of diode D2 is mainly and prevents that capacitor C from discharging when lighter is covering.
The utility model adopts highly sensitive photoelectric transformer, use faint lamp as the signal source of opening oscillating circuit (i.e. igniting), avoided the weak point that adopts contact switch to bring, the reliability and the service life of having improved complete machine, operated more easy; The use of combination mu balanced circuit has then realized the production domesticization of components and parts.
