Abstract

A multifunctional safety gas flow regulator controller, mainly composed of an electronic circuit, automatically starts an alarm and controls components that close the gas supply when the flame is accidentally extinguished or when the battery has an inadequate power supply. The controller is characterized by its multifunctional safety controller for proper disposal of gas tools.

Claims

1. A high voltage electronic ignition circuit of a controller for a multifunctional safety gas flow regulator having a main flame and a mother flame, said high voltage electronic ignition circuit comprising:

an induction electrode for detecting ignition of the mother flame and for stopping ignition after the mother flame ignites;

first biasing means, connected to said induction electrode, for biasing said induction electrode;

a first vibration loop means connected to said first biasing means, for producing an electric voltage;

a rectifying means connected to said first vibration loop means, for rectifying the voltage from said first vibration loop;

a charging circuit means, connected to said rectifying means, for producing a charging voltage;

an ignition electrode, connected to said charging circuit means and ground, for ignition of the mother flame by said charging voltage;

an automatic charging loop means, connected to said first biasing means, for controlling the gas supply for the mother flame and for ignition of the mother flame;

a power source means connected to said automatic charging loop means;

a switch means connected to said power source means, said automatic charging loop means and ground, for turning the high voltage electronic ignition circuit on and off;

a control means, connected to said automatic charging loop means and said first vibration loop means, for controlling gas supply of the mother flame and for controlling sounding an alarm;

a solenoid means connected to said control means and said automatic charging loop means, for controlling the gas to flow to the mother flame;

second biasing means connected to said control means and to ground for producing a biasing signal;

second vibration loop means connected to said second biasing means and said control means for producing an alarm generating signal and

horn means, connected to said second vibration loop means, for sounding the alarm, wherein the alarm is automatically started when either one of the main flame or the mother flame are extinguished and when a power shortage occurs and wherein said ignition circuit functions as a multifunctional safety controller which controls the gas supply to the main flame or mother flame when the induction electrode is grounded.

2. An electronic circuit as set forth in claim 1, wherein when the switch means is ON, the automatic charging loop means discharges, and the solenoid means of a first electromagnetic valve is magnetically excited to cause the flowing out of gas through a nozzle of the mother flame, bias is produced by the first biasing means which produce the voltage of the first vibration loop to be rectified by the rectifying means and then transferred to the charging circuit means, when the electrical voltage has reached a certain valve, the charging circuit means is discharged and a large current is produced to form a high electrical voltage, and as a result, electronic ignition is made by the ignition electrode to burn the gas flowing out from the mother nozzle to become the mother flame.

3. An electronic circuit as set forth in claim 2, wherein during the ignition process of the mother flame, a solenoid of a second electromagnetic valve has no electric current passing through which makes a differential membrane close the gas supply for the main flame.

4. An electronic circuit as set forth in claim 2, wherein when the mother flame is formed, the induction electrode induces a current to maintain magnetic excitement of the solenoid means after the automatic charging loop means discharges to the biasing means and as a result, no bias is applied to the first vibration loop so that no electrical voltage is supplied for charging the charging circuit means so that the ignition electrode stops ignition.

5. An electronic circuit as set forth in claim 4, wherein when ignition electrode stops ignition, the solenoid is charged to make the differential membrane open the gas supply for the main flame to accept the ignition of the mother flame to become the main flame.

6. An electronic circuit as set forth in claim 2 wherein if the automatic charging loop is discharged and the mother flame has not been ignited yet, then the induction electrode has no induction current, the solenoid means of the first electromagnetic valve is cut off to automatic close the gas supply for the mother flame.

7. An electronic circuit as set forth in claim 6, wherein when the mother flame is closed, the second vibration loop makes the horn means sound to indicate to turn off a switch axle for gas supply so that the switch means is OFF, the horn means then stops sounding.

8. An electronic circuit as set forth in claim 4, wherein when ignition electrode stops ignition, the first vibration circuit means produces negative voltage which makes the control means conduct positive voltage to the second vibration loop to inhibit the horn means from sounding indicating gas flow regulator is in normal operation and the horn means will not give the alarm.

9. An electronic circuit as set forth in claim 1 wherein if electrical voltage of the power source means is higher than a forward voltage of the second biasing means, the second biasing means prevents the horn means from sounding indicating the electrical voltage of battery is normal and requires no replacement.

10. An electronic circuit as set forth in claim 9, wherein if electrical voltage of the power source means is lower than the forward voltage of the second biasing means, the second biasing means sends positive electricity to the second vibration loop means so that the horn means is forced to sound indicating that the electrical voltage of the power source means is low and should be replaced.

11. An electronic circuit as set forth in claim 1, wherein if induction electrode is grounded, then during the process of ignition, since the induction electrode is grounded, the solenoid means functions to close the power source means for the main flame to assure safety.
