[Embodiment] In the first figure, a detailed circuit of an ignition electrode inductive automatic igniter 10 suitable for six furnaces is shown, which can be used to illustrate the creation. The automatic igniter 10 is formed by a switching circuit 2, an ignition circuit 30 and an inductive circuit 40 connected by a line of a drawing or a certain logic line. The switch circuit 20 includes a transistor Q1, an ignition switch SW1-SW6, and a diode D1-D12. Each of the ignition switches SW1_SW6 is used with two diodes D1_D12 to prevent reverse current flow and ensure each ignition switch. The operation of SW1-SW6 does not expect the action of other points (four) off. The ignition circuit 30 is mainly composed of transistors q2 and q3, booster coil T7, diode D13, trigger diode D14, capacitor c2, and ignition coils Τ1-Τ6 of the same number as the ignition switches SW1-SW6; The primary side of the ignition coils Τ1-Τ6 are connected, and the one terminal of the secondary side (HV.

Each of the induction coils T8 and T9 includes a primary side and two or more secondary sides. In the embodiment of the first figure, each of the induction coils T8 and T9 has three secondary sides, so that two The number of the secondary side is the same as the total number of the ignition coils T1-T6; wherein the primary sides of the induction coils T8 and T9 are respectively connected to an electro-crystal, Lu Q10 and Q11, for the secondary side oscillation boosting, each time twice One terminal on the side is connected to a field effect transistor (FET) Q4_Q9 via a resistor R12-R17, and the other terminal is connected to another line on the secondary side of an ignition coil T1-T6 via resistors R5-R10 and R26-R31.

In the ignition electrode induction type igniter 1Q thus constructed, when the ignition switches SW1 - SW6 are in the OFF state, the switching circuit 2, the ignition circuit 3, and the induction circuit 40 are in a stationary state. When any of the ignition switches SW1-SW6 is ON, the transistor in the switching circuit 2〇 is turned on, and the ignition circuit 30 and the sensing circuit 40 are supplied with the required operating voltage to be subjected to the ignition switches SW1-SW6. The controlled ignition coils T1-T6 can generate a high voltage and turn on the transistors Q10 and Q11 of the induction circuit 4, so that the induction coils D8 and D9 remain in the flame signal detection state. Wherein: When the ignition switch SW1 is 〇N, since the field effect transistor q4 is turned on, the transistor Q3 in the ignition circuit 30 is not supplied with a positive voltage, so that the transistor q2 leads 8 M320043, and the boosting coil T7 generates an oscillation boost, and Charging the capacitor C2 via the diode D1 3 causes the trigger diode D14 to trigger, and supplies power to the ignition coil T1 to boost the secondary side of the ignition coil T1 to generate a high voltage, and the generated high voltage is transmitted to the high voltage wire to the high voltage wire.

When the HV (high voltage) end of the ignition coil T1 senses the flame signal, an AC voltage is applied through the resistors R26 and R5 and boosted by the first secondary side of the induction coil T8, and then regulated by the Zener diode ZD1. And the capacitor ^ C16 eliminates the noise, and then the field effect transistor Q4 is triggered by the resistor R12 to become an open state (Open) state, so that the transistor Q3 is turned on, the transistor Q2 is turned off, and the ignition coil T1 stops the high voltage ignition. When the ignition switch SW2 is ON, the field effect transistor Q5 is turned on, and the transistor Q3 in the ignition circuit 30 is not supplied with a positive voltage, so that the transistor Q2 is turned on, the boosting coil T7 is oscillated and boosted, and is passed through the diode D13.

(Arc) and ignite * gas-air mixture. When the HV (high voltage) end of the ignition coil T2 senses the fire and flame signals, an alternating voltage is applied through the resistors R27 and R6 and boosted by the second secondary side of the induction coil T8 - to utilize the Zener diode The ZD2 voltage regulator and the capacitor C17 eliminate the noise, and then the resistor R13 triggers the field effect transistor Q5 to be in an open state, so that the transistor Q3 is turned on, the transistor Q2 is turned off, and the ignition coil T2 thus stops the high voltage ignition. When the ignition switch SW3 is ON, the field effect transistor Q6 is turned on, and the transistor Q3 in the ignition circuit 30 has no positive voltage supply, so the transistor Q2 leads 9 M320043, and the coil T7 generates the vibration plate booster The pole D13 charges the capacitor C2 to trigger the trigger diode D14, and supplies power to the ignition coil T3 to boost the secondary side of the ignition coil T3 to generate a high voltage, and the generated high voltage is transmitted to the ignition electrode via the high voltage wire.

When the HV (high voltage) end of the ignition coil T3 senses the flame signal, an AC voltage is applied through the resistors R28 and R7 and boosted by the third secondary side of the induction coil T8, and then regulated by the Zener diode ZD3. And the capacitor ^ C18 eliminates the noise, and then the resistor R14 triggers the field effect transistor Q6 to become an open φ (Open) state, so that the transistor Q3 is turned on, the transistor Q2 is turned off, and the ignition coil T3 thus stops the high voltage ignition. When the ignition switch SW4 is 〇N, the field effect transistor Q7 is turned on, and the transistor Q3 in the ignition circuit 30 is not supplied with a positive voltage, so that the transistor Q2 is turned on, the boosting coil T7 is oscillated and boosted, and passes through the diode D13. Charging the capacitor C2 causes the trigger diode D14 to trigger, and supplies power to the ignition coil T4 to boost the secondary side of the ignition coil T4 to generate a high voltage, and the generated high voltage is transmitted to the ignition electrode via the high voltage wire to generate Spark (arc) to ignite the ® gas-air mixture. When the HV (high voltage) end of the ignition coil T4 senses a fire. When talking about the signal, an AC voltage is applied through the resistors R29 and R8, and the first secondary side of the induction coil T9 is boosted - after the Zener diode The body ZD4 voltage regulator and the capacitor C19 eliminate the noise, and then the resistor R15 triggers the field effect transistor Q7 to be in an open state, so that the transistor Q3 is turned on, the transistor Q2 is turned off, and the ignition coil T4 stops the high voltage ignition. When the ignition switch SW 5 is Ο N, since the field effect transistor Q 8 is turned on, the transistor Q3 in the ignition circuit 30 has no positive voltage supply, so the transistor Q2 conducts M320043, and the boosting coil T7 generates an oscillating boost, and The diode D13 charges the capacitor C2 to trigger the trigger diode D14, and supplies power to the ignition coil T5 to boost the secondary side of the ignition coil T5 to generate a high voltage, and the generated high voltage is transmitted to the ignition electrode via the high voltage wire.

When the HV (high voltage) end of the ignition coil T5 senses the flame signal, an AC voltage is applied through the resistors R30 and R9 and boosted by the second secondary side of the induction coil T9, and then regulated by the Zener diode ZD5. And the capacitor 'C20 eliminates the noise, and then the resistor R16 triggers the field effect transistor Q8 to become the open circuit φ (Open) state, so the transistor Q3 is turned on, the transistor Q2 is turned off, and the ignition coil T5 thus stops the high voltage ignition. When the ignition switch SW6 is ON, the field effect transistor Q9 is turned on, and the transistor Q3 in the ignition circuit 30 is not supplied with a positive voltage, so that the transistor Q2 is turned on, the boosting coil T7 is oscillated and boosted, and is passed through the diode D13. The charging of the capacitor C2 causes the triggering diode D14 to trigger, and supplies power to the ignition coil T6, so that the secondary side of the ignition coil T6 is boosted to generate a south voltage, and the generated south voltage is transmitted to the ignition electrode via the local pressure wire to generate Spark (arc) to ignite * gas-air mixture. When the HV (high voltage) end of the ignition coil T6 senses the fire_flame signal, an alternating voltage is applied through the resistors R31 and R10, and boosted by the third secondary side of the induction coil -T9, using the Zener diode The ZD6 voltage regulator and the capacitor C21 eliminate the noise, and then the field effect transistor Q9 is turned on by the resistor R17 to become an open state, so that the transistor Q3 is turned on, the transistor Q2 is turned off, and the ignition coil T6 stops the high voltage ignition. When any of the ignition switches SW1-SW6 is in the 〇N state, if the HV end of the corresponding ignition coil T1-T6 does not sense the flame signal, the ignition coil will continue to generate a high voltage for the M320043, and the forced ignition function is performed to prevent the safety of the gas. .

The ignition electrode inductive automatic igniter 10c disclosed in this embodiment differs from the embodiment shown in the third figure in that a gas is opened and closed. Solenoid valve SV of the passage. When the ignition switch SW1 is ON, the transistor 〇彳 is turned on, and the positive voltage is supplied to the solenoid valve SV via its c pole, so that the solenoid valve SV is actuated to open the valve position, and the gas flow is allowed to be turned to the gas appliance. Supplying the need for combustion; when the ignition switch SW1 is Off, the electric crystal Q1 is turned off, thereby cutting off the current supplied to the solenoid valve sv, so that the electromagnetic: valve SV is closed to stop the supply of air. In the embodiment of the fourth figure, The switch circuit 20c is selected to include a temperature switch TW1 Connected between the ignition switch SVV1 and the transistor Q1, the temperature switch TW1 is maintained in the 〇N state when the target temperature is lower than the predetermined temperature, so that the solenoid valve SV can obtain the current from the transistor Q1 and actuate to open the valve position; When the temperature exceeds the predetermined temperature, the operation is OFF, and the B pole of the transistor Q1 is turned off due to no voltage supply. Therefore, the current supplied from the transistor Q1 to the solenoid valve sv is cut off to close the solenoid valve sv. 12 M320043 : It belongs to the inductive load. At the moment when the voltage is applied, it will flow the pot: Shi I is sobbing, dozens of times of surge current, so it is necessary to supply the solenoid valve ~ ^ to make the solenoid valve act, then as long as the current is small:匕 Keep the solenoid valve in the open position. Because the general cut-off is very short, only about 〇n 4 , \, name, 2_〇_1 seconds, if the output current is always the value of the match/wave pack* 'The power consumed by the solenoid valve can be large and uneconomical. Therefore, in a preferred embodiment, a power saving circuit can be added to the embodiment shown in the fourth figure to achieve power saving purposes. The fifth figure shows that there is a province. Ignition electrode inductive automatic point of electric circuit 50 (10), the output end of the power-saving circuit 50 is electrically connected to the electromagnetic valve sv, mainly composed of a transistor Q14_Q16 and a resistor=35-R38. Accordingly, when the ignition switch swi is 〇N, the electric body Q1 ^ Passing 'positive' through the resistors R35 and R36 makes the transistors Q15 and Q16 turn on, and supplies a large current to the electromagnetic 阙sv, so that the electromagnetic 阙sv can be actuated to open the valve position; when the hv (high voltage) end of the ignition coil T1 feels f When talking to the fire, the field effect transistor Q4 is in a closed state, so the electric body Q14 is turned on 'the transistors Q15 and Q16 are turned off, and the small current from the resistor R38 is supplied to the solenoid valve SV' to keep the solenoid valve SV open. According to the original creation, the ignition electrode can also function as a sensing electrode, which is used to sense the flame signal after ignition, and at the same time reduce the number of induction coils and reduce the manufacturing cost. In addition, the power saving circuit can supply a large current of the electromagnetic valve to operate, and then supply a small current to keep the electromagnetic valve in the open position, thereby reducing power consumption. In addition, a temperature switch is used as the temperature detector, and the target temperature is 13
