Definitions

  • the present invention relates to a spark-producing device employing a battery for use especially in lighters having voltage transducers capable of oscillations for producing a high voltage spark and including a cut-in an'd cut-out switch which is operable by the operating member of the spark-producing device itself so as to throw the voltage transducer into and out of the circuit.
  • Spark-producing arrangements employing batteries are already known in which a storage capacitor is charged up directly from the battery and is discharged through a high voltage ignition transformer by operating an actuating contact.
  • Such an arrangement has a disadvantage in that the ignition transformer must have a very high transformer ratio and a multi-cell battery is necessary. For such reasons a spark-producing device of the above kind is relatively bulky.
  • Another spark-producing device employing a battery became known which has a voltage transducer capable of oscillations and through which a storage capacitor is charged to a voltage which is several times higher than the battery voltage itself. After charging up the capacitor, the storage capacitor becomes discharged through an ignition transformer after a switch becomes operated. As is evident from the above, an additional transformer is necessary for the oscillating part of the voltage transducer.
  • the last mentioned arrangement operates with a single cell battery and its ignition transformer requires a relatively small transformer ratio and, therefore, its volume can be kept relatively small.
  • the disadvantage of the above-mentioned sparkproducing arrangement resides in that it remains in operation for as long as the operating switch of the lighter is closed, even after ignition has taken place. In the case of pocket lighters, such repeated and superfluous ignition will lead to a quick exhaustion of the battery.
  • an object of the present invention to provide an improved spark-producing arrangement employing a battery which does not have the abovementioned disadvantages of known spark-producing devices and which is capable of increasing thereby the operating life of the battery.
  • a flame sensing means is provided within the spark-producing arrangement which controls a cut-out member of the ignition device.
  • a sparkproducing arrangement employing a battery and having a transistorized voltage transdusing arrangement therein
  • the cut-out member is preferably provided in the feedback path of the voltage transducer and located in the base circuit of the transducer.
  • the flame sensing means forms the cut-out member itself.
  • FIG. 1 illustrates the circuit connections of a sparkproducing device employing a battery according to the present invention
  • FIGS. 2a-f illustrate various flame sensing devices which can be used in connection with this sparkproducing arrangement according to the present invention.
  • FIG. 1 DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the circuit diagram of FIG. 1, it is seen that it includes a battery 1, which preferably has a voltage of 1.5 volts, and an electrolyte capacitor 2, which is connected parallel to the battery 1.
  • the fact that such a type of capacitor is used has the advantage that even when the battery has been relatively fully discharged, the spark-producing arrangement of the present invention will still be capable of proper functioning.
  • the circuit diagram further includes a npn-type transistor 5, which obviously can also be a pnp-type and, in the latter case, it is required only to change the voltage polarities.
  • the emitter of the transistor 5 is connected to the negative terminal of the battery 1, while the collector is connected over the primary winding 6 of an oscillation transformer 9, with the make-contact of an operating switch 10, the other contact point of which is returned to the positive terminal of the battery 1.
  • the oscillating transformer 9 further includes a feedback winding 7 as well as a secondary winding 8.
  • the feedback winding 7 is connected with one end thereof to the base of the transistor 5 and with the other end thereof to a tap-joint of a voltage divider circuit feeding the base of the transistor 5 and comprising the resistors 3 and 4.
  • One end of the voltage divider circuit is connected to ground, namely. at one end of the resistor 4,
  • the secondary winding 8 of the oscillating transformer 9 has a Villard-type rectifier arrangement coupled thereto which includes a storage capacitor 11, diodes 12 and 13 and another storage capacitor 14.
  • the primary winding 15 of a high voltage ignition transformer 17 is connected through a series circuit, including a thyristor 18.
  • the secondary side 16 of the high voltage ignition transformer 17 is in circuit connection with a spark gap 21.
  • a flame-sensitive sensing means which controls a cut-out switch member of the ignition arrangement.
  • the resistor 3 in the voltage divider circuit feeding the base of transistor 5 is replaced by a switch member which is placed in the operating range of the burning flame which includes a resistive part, the resistance of which increases with increasing flame temperature.
  • PTC positive temperature co-efficient
  • switching member which has a resistance characteristic decreasing with increasing temperature.
  • NTC negative temperature co-efficient
  • FIG. 2e Another embodiment possible for sensing the flame temperature and to acting as a cut-out switch is when the resistor 4 is replaced by an infrared sensor, such as, by an infra-red sensitive photo-resistor. This type of arrangement is illustrated in FIG. 2e.
  • a so-called ionization gap 22, illustrated in FIG. 2f which can be in the form of a pair of wire tips placed at a small distance with respect to each other.
  • Such an ionization gap could then be used to replace the resistor 4. It is, however, assumed and required that the resistor 3 always has a value which is considerably larger than the resistance of the ionization gap 22.
  • the resistance of the gap 22 at an operating flame lies between I and 20 M ohms. It is also noted that that, for the generally illustrated transistor 5, it is preferred to use a FET-type transistor which requires a very slight base current.
  • the gap 22 may be arranged in such a manner that the gap 22 controls a switching member such as an FET transistor which lies parallel with the resistor 4.
  • the circuit of the oscillating arrangement must be designed in such a manner that when the operating switch is closed, then the oscillation will start.
  • the above requirement can be obtained by the appropriate dimensioning of the switching elements, especially by appropriately selecting the bias voltage for the base of the transistor 5, the winding ratio of the primary winding 6 and the feedback winding 7.
  • the circuit arrangement illustrated in FIG. I operates as follows:
  • the circuit diagram illustrated in FIG. 1 is designed in such a manner that the oscillations will continue after the storage capacitor 14 has discharged and the above described oscillating process keeps repeating itself.
  • the voltage transducer or oscillator will turn itself off only when the gas or whatever fuel is used is already burning.
  • the resistor 3, as above described can be made as a PTC resistor which is placed in the operating range of the flame. Due to the heat produced by the flame, the resistance of the PTC resistor 3 will increase itself considerably within a short period of time so that the bias voltage of the transistor base will be reduced to a value which is too small for another cycle of oscillation. It is assumed that the oscillating state of the voltage transducer or oscillator portion is relatively difficult to upset by changing the bias voltage of the transistor base.
  • the resistor is a NTC resistor. as illustrated in FIG. 2c, then the resistance value of such a reistor will decrease considerably through the exposure to the heat of the flame and thereby the bias voltage to the base of transistor 5 will be reduced with the consequence, as mentioned above in connection with the PTC resistor, namely the oscillation will stop.
  • the resistor 4 can be replaced by an infra-red sensitive photo-resistor as illustrated in FIG. 22. Such a photo-resistor reduces its resistance value when radiation hits it, so that it will have a similar effect as when a NTC resistor is used.
  • the switching arrangement illustrated in FIG. 1 can be modified several ways.
  • a self-cleaning or wiping contactor can be used, which, after having been operated once allows the sparking to go on only for a certain number of times before the switch can be operated again.
  • an excessive use of the battery is avoided and this is especially advantageous in the event other operating deffects are present or when the fuel tank is empty.
  • a spark-producing circuit comprising a source of DC. voltage, an oscillating means including spark means coupled to said course of DC. voltage, a sensing means placed adjacent said flame and sensing the presence of the flame for turning off said oscillating means when a flame is present, said oscillating means comprises a voltage transducer means having a primary, a
  • a transistor device having a base electrode connected to said feedback winding, a primary winding connected to said collector electrode, a voltage dividing circuit including said sensor means connected through said feedback winding to the base electrode of said transistor device, an operating switch means connecting said voltage divider circuit to one terminal of said DC.
  • a discharge circuit connected to said secondary winding and including a storage capacitor means and a thyristor device connected in a series therewith and capable of producing a high voltage pulse when the charge in said storage capacitor attains a predetermined breakdown voltage of said thyristor means, a high voltage step-up transformer means having a primary winding connected in series with said storage capacitor means and said thyristor means and a secondary winding, a spark gap means connected in series with said secondary winding of said step-up transformer means, whereby a spark is produced in said spark gap means when said storage capacitor discharges over said thyristor device.
