Description

Technical Field

[0001] This application relates to the field of intelligent device technology, such as methods, devices, gas stoves, and storage media for controlling the ignition circuit of gas stoves. Background Technology

[0002] Currently, smart home appliances have permeated various appliance categories, with televisions, refrigerators, air conditioners, and washing machines increasingly incorporating smart features. Gas stoves also have control devices and can be intelligently controlled, such as providing gas alarms.

[0003] However, pulse ignition is still widely used in gas stoves. Current pulse ignition circuits employ a self-excited oscillating circuit with positive feedback formed by transformer coupling. This circuit boosts the battery voltage; when the voltage reaches a sufficiently high level, it breaks down the air between the discharge needle and the combustion plate, creating a momentary electric spark. The energy of this spark ignites the gas, thus completing the ignition. The ignition frequency, i.e., the number of sparks per second, is related to the power supply voltage. Since most gas stoves use dry cell batteries as a power source, the battery voltage gradually decreases with use, reducing the ignition frequency and reliability, thus increasing the risk of deflagration. Summary of the Invention

[0004] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0005] This disclosure provides a method, apparatus, gas stove, and storage medium for controlling an ignition circuit of a gas stove, in order to solve the technical problem that the reliability of gas stove ignition needs to be improved.

[0006] In some embodiments, the gas stove ignition circuit includes: a power supply, an oscillation circuit, a high-voltage discharge circuit, and a gas stove control device, wherein the base of the transistor VT in the oscillation circuit is connected to the first interface of the gas stove control device.

[0007] The gas stove control device generates a periodic digital pulse voltage based on the current voltage value of the power supply, and outputs it to the base of the transistor VT through the first interface. This causes the energy generated by the oscillation circuit to be transferred to the high-voltage discharge circuit through the first transformer T1, which in turn induces a pulse voltage of more than 10,000 volts on the fifth coil L5 of the second transformer T2 in the high-voltage discharge circuit, generating a discharge spark.

[0008] In some embodiments, the method includes:

[0009] Obtain the current voltage value of the power supply in the gas stove ignition circuit;

[0010] The current oscillation frequency is obtained based on the rated voltage value of the power supply, the current voltage value, and the rated oscillation frequency of the gas stove ignition circuit;

[0011] Based on the current oscillation frequency, a periodic digital pulse voltage is generated and output to the base of the transistor VT in the oscillation circuit of the gas stove ignition circuit, thereby controlling the gas stove ignition circuit to generate a discharge spark.

[0012] In some embodiments, the device includes:

[0013] The acquisition module is configured to acquire the current voltage value of the power supply in the gas stove ignition circuit;

[0014] The determining module is configured to obtain the current oscillation frequency based on the rated voltage value of the power supply, the current voltage value, and the rated oscillation frequency of the gas stove ignition circuit;

[0015] The output control module is configured to generate a periodic digital pulse voltage according to the current oscillation frequency and output it to the base of the transistor VT in the oscillation circuit of the gas stove ignition circuit to control the gas stove ignition circuit to generate a discharge spark.

[0016] In some embodiments, the device for controlling the ignition circuit of a gas stove includes a processor and a memory storing program instructions, wherein the processor is configured to execute the above-described gas stove ignition circuit control method when executing the program instructions.

[0017] In some embodiments, the gas stove includes the aforementioned device for controlling the gas stove ignition circuit.

[0019] The gas stove ignition circuit, control method, device, and gas stove provided in this disclosure can achieve the following technical effects:

[0020] The base of the transistor in the oscillation circuit of the gas stove ignition circuit is controlled by the gas stove control device. After obtaining the current voltage value of the power supply in the gas stove ignition circuit, the gas stove control device can determine the matching current oscillation frequency. Based on the current oscillation frequency, it generates periodic digital pulse voltages and outputs them to the base of the transistor in the oscillation circuit. This controls the gas stove ignition circuit to generate a discharge spark. By correcting the oscillation frequency, it ensures that the second capacitor in the high-voltage discharge circuit can be charged to the same voltage within the same time period, guaranteeing the number of breakdown discharges. That is, regardless of whether the power supply voltage decreases, the ignition frequency will not decrease, improving the reliability of ignition and reducing the risk of combustion and explosion.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0031] Unless otherwise stated, the term "multiple" means two or more.

[0032] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0033] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0034] In related technologies, the ignition circuit of a gas stove uses a self-excited oscillation circuit that utilizes transformer coupling to form positive feedback.

[0035] Figure 1 This is a structural diagram of an ignition circuit for a gas stove provided by related technologies. Among them, such as... Figure 1 As shown, it includes: a power supply 100, an oscillation circuit 200, and a high-voltage discharge circuit 300.

[0036] The power source 100 may include: a dry cell battery or a rechargeable power supply, such as... Figure 1 As shown, Ec can be the power supply, typically rated at 1.5V. The first capacitor C1, the first resistor R1, the transistor VT, and the first transformer T1 form the oscillation circuit 200, where the first transformer T1 includes the first coil L1, the second coil L2, and the third coil L3. The first diode VD1, the second resistor R2, the second capacitor C2, the second diode VD2, the third capacitor C3, and the second transformer T2 form the high-voltage discharge circuit, where the second transformer T2 includes the fourth coil L4 and the fifth coil L5.

[0037] When button S is triggered, the power supply Ec in the gas stove ignition circuit is turned on. This provides a base current to the 200Ω transistor VT in the oscillation circuit via resistor R1. Consequently, the collector current of VT begins to increase. Through the coupling effect of coils L1 and L2 in the first transformer T1, an induced electromotive force (EMF) is generated in L1. This EMF, superimposed on the power supply voltage, further increases the base current and collector current, creating a strong positive feedback loop. This causes VT to quickly reach saturation. At this point, the collector current stops increasing, the induced EMF in L1 decreases, and the base current and collector current of VT begin to decrease, thus forming another positive feedback process. As a result, VT quickly enters the cutoff state. During this process, the energy of L2 in the first transformer T1 is transferred to L3. Once the magnetic energy in L2 is exhausted, the base potential of VT decreases again, causing VT to conduct again and enter a new oscillation cycle.

[0038] When the induced electromotive force of L3 in the first transformer T1 turns on VD1 in the high-voltage discharge circuit 300, capacitor C3 is charged through L4, and C2 is also charged through R2. Before the voltage of C2 reaches the turn-on voltage of the trigger diode VD2, the voltage of C3 increases. When the voltage of C2 reaches the turn-on voltage of the trigger diode VD2, VD2 breaks down, and capacitor C2 discharges through VD2 to the trigger electrode of the thyristor, turning on the thyristor SCR and rapidly discharging the energy stored in C3. This induces a pulse voltage of over 10,000 volts at L5, generating a discharge spark.

[0039] It is evident that in the relevant technologies, the ignition frequency of the gas stove ignition circuit is directly determined by the charging time of C2; the oscillation period of VT determines the charging time of C2; and the charging time of C2 is determined by the hardware circuit parameters and the power supply voltage. Therefore, a change in the power supply voltage will change the ignition frequency.

[0040] When using dry cell batteries or rechargeable batteries in the ignition circuit of a gas stove, the voltage of a new battery or a fully charged battery is around 1.5V. Generally, it cannot be used when the voltage drops to 0.9V. Such a large range of voltage fluctuations results in a large variation in the ignition frequency. Tests have shown that the lowest ignition frequency can be as low as 1Hz, which is once per second, and the highest ignition frequency can be as high as 16Hz, which is 16 times per second.

[0041] A decrease in the ignition frequency of a gas stove's ignition circuit reduces its ignition reliability and poses a risk of deflagration. Therefore, in this embodiment, the base of VT in the oscillation circuit can be controlled by the gas stove control device. This allows the control device to obtain the current voltage value of the power supply in the ignition circuit, determine the matching current oscillation frequency, and generate periodic digital pulse voltages based on this frequency. These pulses are then output to the base of the transistor in the oscillation circuit, thereby controlling the ignition circuit to generate a discharge spark. By correcting the oscillation frequency, it ensures that the second capacitor in the high-voltage discharge circuit can be charged to the same voltage within the same timeframe, guaranteeing the number of breakdown discharges. This means that regardless of whether the power supply voltage decreases, the ignition frequency remains constant, improving ignition reliability and reducing the risk of deflagration.

[0042] Figure 2 This is a schematic diagram of the structure of an ignition circuit for a gas stove provided in an embodiment of this disclosure. Figure 2 As shown, the gas stove ignition circuit control system includes: a power supply 100, an oscillation circuit 200, a high-voltage discharge circuit 300, and a gas stove control device 400. Here, the gas stove control device can be a microcontroller unit (MCU), although other control chips can also be used, which will not be listed here.

[0043] Among them, with Figure 1 Compared to the gas stove ignition circuit shown in the related technology, the oscillation circuit 200 has changed, excluding R1 and C1, and the first transformer T1 only has the second coil L2 and the third coil 3. Furthermore, a gas stove control device, i.e., an MCU, has been added to the gas stove ignition circuit, and the base of the transistor (VT) in the oscillation circuit 200 is connected to the first interface of the gas stove control device 400.

[0044] Therefore, the gas stove control device 400 generates a periodic digital pulse voltage according to the current voltage value of the power supply, and outputs it to the base of the transistor VT through the first interface. This causes the energy generated by the oscillation circuit 200 to be transferred to the high-voltage discharge circuit 300 through the first transformer T1, which in turn induces a pulse voltage of more than 10,000 volts on the fifth coil L5 of the second transformer T2 in the high-voltage discharge circuit 300, generating a discharge spark.

[0045] During ignition, button S is triggered, and the power supply Ec in the gas stove ignition circuit is turned on. The MCU of the corresponding gas stove control device 400 outputs a low level to the base of transistor VT, turning VT on. The collector current of VT increases rapidly through the L2 coil. At this time, due to the winding direction of the L3 coil, its induced voltage is positive at the bottom and negative at the top. Diode VD1 is cut off and there is no current, and the L2 coil stores energy. After 1 / 2 T, the MCU outputs a high level to the base of transistor VT, and VT turns off and enters the cutoff state. The current in the L2 coil drops rapidly to 0, and the induced voltage in the L3 coil is positive at the top and negative at the bottom. VD1 conducts, and the energy stored in L2 is transferred to L3. After 1 / 2 T, the MCU outputs a low level, turning VT on again and entering a new oscillation cycle.

[0046] Of course, when the induced electromotive force of L3 in the first transformer T1 turns on VD1 in the high-voltage discharge circuit 300, C3 is charged through L4, and C2 is also charged through R2. Before the voltage of C2 reaches the turn-on voltage of the trigger diode VD2, the voltage of C3 increases. When the voltage of C2 reaches the turn-on voltage of the trigger diode VD2, VD2 breaks down, and capacitor C2 discharges through VD2 to the trigger electrode of the thyristor, turning on the thyristor SCR and rapidly releasing the energy stored in C3. This induces a pulse voltage of over 10,000 volts at L5, generating a discharge spark.

[0047] As can be seen, the MCU outputs periodic digital pulse voltages, and the corresponding oscillation frequency is the reciprocal of the period, i.e., T=1 / F. The turn-on and turn-off times T can be calculated from the oscillation frequency.

[0048] Furthermore, a power source with voltage U charges a capacitor C with an initial value of 0 through a resistor R. At any time t, the voltage across the capacitor is: Vt = U × [1 - exp(-t / RC)]; where exp() represents an exponent with base e. Based on the above capacitor charging formula, it can be determined that the capacitor voltage is proportional to the power source voltage.

[0049] Therefore, in this embodiment of the invention, for the gas stove ignition circuit, when the voltage corresponding to the power supply Ec drops by a certain percentage, to charge capacitor C2 to a certain voltage within the same time period, it is only necessary to increase the number of VT oscillations proportionally, i.e., increase the number of times C2 is charged. Therefore, if the rated voltage of the battery corresponding to the power supply Ec is E, and the rated oscillation frequency is F; when the MCU detects that the current battery voltage is E1, it can determine that the current oscillation frequency should be...

[0050] F1=F+F×(1- E1 / E)(1)

[0051] Where F1 is the current oscillation frequency, F is the rated oscillation frequency, E is the rated voltage value, and E1 is the current voltage value.

[0052] As can be seen, the base of the transistor in the oscillation circuit of the gas stove ignition circuit is controlled by the gas stove control device. Thus, after obtaining the current voltage value of the power supply in the gas stove ignition circuit, the gas stove control device can determine the matching current oscillation frequency. Based on the current oscillation frequency, it generates periodic digital pulse voltages and outputs them to the base of the transistor in the oscillation circuit, thereby controlling the gas stove ignition circuit to generate a discharge spark. By correcting the oscillation frequency, it ensures that the second capacitor in the high-voltage discharge circuit can be charged to the same voltage within the same time frame, guaranteeing the number of breakdown discharges. That is, regardless of whether the power supply voltage decreases, the ignition frequency will not decrease, improving the reliability of ignition and reducing the risk of combustion and explosion.

[0053] With the development of smart technology, home appliances such as televisions, refrigerators, air conditioners, and washing machines are increasingly incorporating smart features. Therefore, gas stoves are also incorporating smart features, that is, gas stoves have control devices that can detect gas concentration, provide gas alarms, etc. In this embodiment, the control device can also control the gas stove ignition circuit.

[0054] Figure 3 This is a flowchart illustrating a gas stove ignition circuit control method provided in an embodiment of this disclosure. Figure 3 As shown, the process of controlling the ignition circuit of a gas stove includes:

[0055] Step 301: Obtain the current voltage value of the power supply in the gas stove ignition circuit.

[0056] The gas stove incorporates smart features, and naturally, the ignition circuit control device can also perform various detections. Here, it can detect the voltage of the power supply in the gas stove ignition circuit. For example, one interface of the gas stove control device is connected to a voltage detection circuit or voltage sensor. Thus, through the voltage detection circuit or voltage sensor, the voltage value of the power supply in the gas stove ignition circuit can be obtained in real time or at regular intervals, with each acquisition corresponding to the current voltage value.

[0057] In some embodiments, upon receiving an ignition command, the current voltage value of the power supply in the gas stove ignition circuit can be obtained. Alternatively, in situations such as... Figure 2 In the gas stove ignition circuit shown, when button S is triggered, the current voltage value of the power supply in the gas stove ignition circuit can be obtained.

[0058] Step 302: Based on the rated voltage of the power supply, the current voltage, and the rated oscillation frequency of the gas stove ignition circuit, obtain the current oscillation frequency.

[0059] Since the capacitor voltage is proportional to the power supply voltage, in this embodiment of the invention, for the gas stove ignition circuit, when the voltage corresponding to the power supply Ec drops by a certain percentage, to charge capacitor C2 to a certain voltage within the same time, it is only necessary to increase the number of oscillations VT proportionally, i.e., increase the number of times C2 is charged. Therefore, if the rated voltage of the battery corresponding to the power supply Ec is E, and the rated oscillation frequency is F; when the MCU detects that the current battery voltage is E1, it can determine that the current oscillation frequency should be F.

[0060] F1=F+F×(1- E1 / E)(1)

[0061] Where F1 is the current oscillation frequency, F is the rated oscillation frequency, E is the rated voltage value, and E1 is the current voltage value.

[0062] Step 303: Based on the current oscillation frequency, generate a periodic digital pulse voltage and output it to the base of the transistor VT in the oscillation circuit of the gas stove ignition circuit to control the gas stove ignition circuit to generate a discharge spark.

[0063] The period of the periodic digital pulse voltage is T = 1 / F1, therefore, as... Figure 2 In the gas stove ignition circuit shown, the MCU outputs a low level to the base of transistor VT, turning VT on. The collector current of VT increases rapidly through coil L2. At this time, due to the winding direction of coil L3, its induced voltage is positive at the bottom and negative at the top. Diode VD1 is cut off and there is no current, so coil L2 stores energy. After 1 / 2 T, the MCU outputs a high level to the base of transistor VT, turning VT off and entering the cutoff state. The current in coil L2 drops rapidly to 0, and the induced voltage in coil L3 is positive at the top and negative at the bottom. VD1 conducts, and the energy stored in L2 is transferred to L3. After 1 / 2 T, the MCU outputs a low level, turning VT on again and entering a new oscillation cycle.

[0064] Of course, when the induced electromotive force of L3 in the first transformer T1 turns on VD1 in the high-voltage discharge circuit, C3 is charged through L4, and C2 is also charged through R2. Before the voltage of C2 reaches the turn-on voltage of the trigger diode VD2, the voltage of C3 increases. When the voltage of C2 reaches the turn-on voltage of the trigger diode VD2, VD2 breaks down, and capacitor C2 discharges through VD2 to the trigger electrode of the thyristor, turning on the thyristor SCR and rapidly releasing the energy stored in C3. This induces a pulse voltage of over 10,000 volts at L5, generating a discharge spark.

[0065] As can be seen, in this embodiment, the base of the transistor in the oscillation circuit of the gas stove ignition circuit is controlled by the gas stove control device. Thus, after obtaining the current voltage value of the power supply in the gas stove ignition circuit, the gas stove control device can determine the matching current oscillation frequency and, based on the current oscillation frequency, generate a periodic digital pulse voltage, which is then output to the base of the transistor in the oscillation circuit. This controls the gas stove ignition circuit to generate a discharge spark. By correcting the oscillation frequency, it ensures that the second capacitor in the high-voltage discharge circuit can be charged to the same voltage within the same time period, guaranteeing the number of breakdown discharges. That is, regardless of whether the power supply voltage decreases, the ignition frequency will not decrease, improving the reliability of ignition and reducing the risk of combustion and explosion.

[0066] Furthermore, the ignition frequency is controlled by the gas stove's control device, ensuring that the ignition frequency remains stable at the optimal frequency throughout the battery's lifespan, unaffected by battery voltage fluctuations. This means that when the battery voltage is high, the ignition frequency does not need to exceed the optimal frequency, thus reducing battery consumption, increasing battery life, and minimizing ignition needle wear and lifespan. Conversely, when the battery voltage is low, the ignition frequency will not fall below the optimal frequency, increasing the ignition success rate and improving the user experience. Moreover, maintaining a relatively high ignition frequency even at lower voltages reduces the possibility of deflagration.

[0067] Of course, in some embodiments, a battery replacement reminder is triggered when the current voltage value is lower than a set value. This intelligent reminder for battery replacement further enhances the intelligence of the gas stove.

[0068] The following describes the operation process in a specific embodiment, illustrating the gas stove ignition circuit control process provided by the embodiment of the present invention.

[0069] In this embodiment, the gas stove ignition circuit is as follows: Figure 2 As shown, the gas stove control device can be an MCU, the power supply can be a dry cell battery, the rated voltage can be 1.5V, therefore, the corresponding setting value can be 0.9V, and the ignition safety time can be set to 3 seconds.

[0070] Figure 4 This is a flowchart illustrating a gas stove ignition circuit control method provided in an embodiment of this disclosure. Figure 4 As shown, the process of controlling the ignition circuit of a gas stove includes:

[0071] Step 401: Determine if the duration of button S being triggered is ≥3 seconds. If yes, proceed to step 402; otherwise, return to step 401.

[0072] By adjusting the duration of button S's activation, the chance of accidental operation can be reduced, further improving the safety of gas stove use.

[0073] Step 402: Obtain the current voltage value of the power supply in the gas stove ignition circuit.

[0074] The current voltage value of the power supply in the gas stove ignition circuit can be obtained through a voltage detection circuit or a voltage detection sensor.

[0075] Step 403: Determine if the current voltage value is ≥0.9V? If yes, proceed to step 404; otherwise, proceed to step 406.

[0076] Step 404: Obtain the current oscillation frequency according to formula (1).

[0077] F1 is the current oscillation frequency, F is the rated oscillation frequency, E is the rated voltage value, and E1 is the current voltage value.

[0078] Step 405: Based on the current oscillation frequency, generate a periodic digital pulse voltage and output it to the base of transistor VT in the oscillation circuit of the gas stove ignition circuit, controlling the gas stove ignition circuit to generate a discharge spark. This process ends.

[0079] The MCU generates periodic digital pulse voltages and outputs them to the base of transistor VT through the first interface. This causes the energy generated by the oscillation circuit to be transferred to the high-voltage discharge circuit through the first transformer. The energy then charges the second capacitor C2 and the third capacitor C3 in the high-voltage discharge circuit. When the voltage on the second capacitor C2 triggers and breaks down the second diode VD2 in the high-voltage discharge circuit, the third capacitor C3 releases its stored energy, causing a pulse voltage of over 10,000 volts to be induced on the fifth coil L5 in the high-voltage discharge circuit, generating a discharge spark.

[0080] Step 406: Process the replacement reminder.

[0081] The system can remind users to replace the batteries. There are various methods for this reminder, including audio-visual, visual, voice, and text notifications.

[0082] As can be seen, in this embodiment, the base of the transistor in the oscillation circuit of the gas stove ignition circuit is controlled by the MCU. After obtaining the current voltage value of the power supply in the gas stove ignition circuit, the MCU can determine the matching current oscillation frequency and generate periodic digital pulse voltages based on the current oscillation frequency, which are then output to the base of the transistor in the oscillation circuit. This controls the gas stove ignition circuit to generate a discharge spark. By correcting the oscillation frequency, it ensures that the second capacitor in the high-voltage discharge circuit can be charged to the same voltage within the same time period, guaranteeing the number of breakdown discharges. This ensures that the ignition frequency remains stable at the optimal ignition frequency throughout the battery's lifespan, without fluctuations in battery voltage. Thus, when the battery voltage is high, the ignition frequency does not need to exceed the optimal frequency, thereby reducing battery power consumption, increasing battery life, and minimizing ignition needle wear and lifespan. Conversely, when the battery voltage is low, the ignition frequency will not fall below the optimal frequency, increasing the ignition success rate and improving the user experience. Furthermore, maintaining a relatively high ignition frequency even at lower voltages reduces the possibility of deflagration.

[0083] Based on the above process of controlling the ignition circuit of a gas stove, a device for controlling the ignition circuit of a gas stove can be constructed.

[0084] Figure 5 This is a schematic diagram of the structure of a gas stove ignition circuit control device provided in an embodiment of this disclosure. Figure 5 As shown, the gas stove ignition circuit control device can be applied in a gas stove control device, including: an acquisition module 510, a determination module 520, and an output control module 530.

[0085] The acquisition module 510 is configured to acquire the current voltage value of the power supply in the gas stove ignition circuit.

[0086] The determination module 520 is configured to obtain the current oscillation frequency based on the rated voltage value of the power supply, the current voltage value, and the rated oscillation frequency of the gas stove ignition circuit.

[0087] The output control module 530 is configured to generate a periodic digital pulse voltage according to the current oscillation frequency and output it to the base of the transistor VT in the oscillation circuit of the gas stove ignition circuit to control the gas stove ignition circuit to generate a discharge spark.

[0088] In some embodiments, the determining module is specifically configured to obtain the current oscillation frequency according to formula (1).

[0089] F1=F+F×(1- E1 / E)(1)

[0090] Where F1 is the current oscillation frequency, F is the rated oscillation frequency, E is the rated voltage value, and E1 is the current voltage value.

[0091] In some embodiments, the system further includes a replacement reminder module configured to perform a replacement reminder when the current voltage value is less than a set value.

[0092] In this embodiment, the base of the transistor in the oscillation circuit of the gas stove ignition circuit is controlled by the gas stove ignition circuit control device. After obtaining the current voltage value of the power supply in the gas stove ignition circuit, the control device determines the matching current oscillation frequency and generates periodic digital pulse voltages based on this frequency, outputting them to the base of the transistor in the oscillation circuit. This controls the gas stove ignition circuit to generate a discharge spark. By correcting the oscillation frequency, it ensures that the second capacitor in the high-voltage discharge circuit can be charged to the same voltage within the same time frame, guaranteeing the number of breakdown discharges. This ensures that the ignition frequency remains stable at the optimal ignition frequency throughout the battery's lifespan, without fluctuations in battery voltage. Thus, when the battery voltage is high, the ignition frequency does not need to exceed the optimal frequency, thereby reducing battery power consumption, increasing battery life, and minimizing ignition needle wear and extending its lifespan. Conversely, when the battery voltage is low, the ignition frequency will not fall below the optimal frequency, increasing the ignition success rate and improving the user experience. Furthermore, maintaining a relatively high ignition frequency even at lower voltages reduces the possibility of deflagration.

Claims

1. A gas stove ignition circuit, characterized in that, include: The system includes a power supply, an oscillation circuit, a high-voltage discharge circuit, and a gas stove control device. The base of the transistor (VT) in the oscillation circuit is connected to the first interface of the gas stove control device. The high-voltage discharge circuit includes: a first diode (VD1), a second resistor (R2), a second capacitor (C2), a second diode (VD2), a third capacitor (C3), a second transformer (T2), and a thyristor (SCR). The second transformer (T2) includes a fourth coil (L4) and a fifth coil (L5). The gas stove control device generates periodic digital pulse voltages based on the current voltage value of the power supply and outputs them to the base of the transistor (VT) through the first interface. The energy generated by the oscillation circuit is then transferred to the high-voltage discharge circuit via the first transformer (T1). This energy then charges the third capacitor (C3) through the fourth coil (L4) of the second transformer (T2) in the high-voltage discharge circuit, and charges the second capacitor (C2) through the second resistor (R2). When the voltage of the second capacitor (C2) reaches the conduction voltage of the trigger diode (VD2), the second diode (VD2) breaks down. The second capacitor (C2) then discharges through the second diode (VD2) to the trigger electrode of the thyristor (SCR), causing the thyristor (SCR) to conduct and rapidly dissipating the energy stored in the third capacitor (C3). This induces a pulse voltage of over 10,000 volts on the fifth coil (L5) of the second transformer (T2) in the high-voltage discharge circuit, generating a discharge spark.
