Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of gas stove control, and particularly relates to a control device and a control method of a gas stove thermocouple double-coil electromagnetic valve. BACKGROUND

[0002] A conventional gas stove on the market uses a thermocouple and a double-coil electromagnetic valve. The thermocouple can generate an electric signal through the heat generated by a flame to realize flame monitoring and safety protection of the gas stove, and can output the electric signal to the double-coil electromagnetic valve. The double-coil electromagnetic valve can use the electric signals received by two coils to make the electromagnet generate an attractive force, thereby controlling the opening and closing of the valve to realize continuous output or stop of the gas. The two coils are usually divided into a secondary coil for quickly opening the valve and a primary coil for keeping the valve in an open state.

[0003] When controlling the double-coil electromagnetic valve to close the valve, most conventional gas stoves use a boost circuit and a series resistor to make the magnetic field between the electric signal output to the secondary coil of the double-coil electromagnetic valve and the electric signal output to the primary coil cancel each other out, thereby making the electromagnet unable to generate an attractive force on the valve body. When controlling the double-coil electromagnetic valve to open the valve, the conventional gas stove first uses a series resistor to limit current and divide voltage to temporarily output an electric signal to the secondary coil of the double-coil electromagnetic valve, and then outputs an electric signal to the primary coil through the thermocouple, thereby making the electromagnet continuously generate an attractive force on the valve body. Since most gas stoves currently use a battery for power supply, this control method of the double-coil electromagnetic valve can cause a large power consumption of the battery, and can also cause the double-coil electromagnetic valve to fail to close the valve, thereby affecting the service life of the battery and the use experience of the gas stove.

[0055] Please see Figure 1 , Figure 1 The diagram shows a conventional control device for a thermocouple dual-coil solenoid valve in an existing gas stove.

[0056] like Figure 1 As shown, a conventional control device for a thermocouple-coiled solenoid valve in a conventional gas stove may include a thermocouple, a coiled solenoid valve, a series resistor, a voltage control unit, a boost unit, a conduction control unit, and a battery pack, wherein:

[0057] The dual-coil solenoid valve is equipped with a main coil and a secondary coil to control the valve to close or open based on the electrical signals output to the main coil and the secondary coil. One end of the main coil of the dual-coil solenoid valve can be connected to the output terminal of a thermocouple, and the other end of the main coil can be connected to the ground terminal through the housing. Figure 1 (Not shown in the image); one end of the secondary coil of this dual-coil solenoid valve can be connected to one end of a series resistor, and the other end of the secondary coil of this dual-coil solenoid valve can be connected to the positive terminal of the battery pack through the outer casing, or connected to the ground terminal through the outer casing. Figure 1 (Only the connection to the positive terminal of the battery pack is shown in the image).

[0058] The other end of the series resistor can be connected to one end of the voltage control unit and one end of the conduction control unit respectively, so as to achieve current limiting and voltage division in the circuit where the battery pack and the secondary coil of the dual coil solenoid valve are located, thereby ensuring the current demand output to the secondary coil of the dual coil solenoid valve.

[0059] The other end of the voltage control unit can be connected to one end of the boost unit to output the electrical signal output by the boost unit in the form of pulses to one end of the secondary coil of the dual coil solenoid valve. The voltage control unit can be, but is not limited to, a field-effect transistor control circuit or a load switch control circuit well known in the art. Its specific structure and control principle will not be elaborated here.

[0060] The other end of the boost unit can be connected to the positive terminal of the battery pack to boost the electrical signal output by the battery pack. For example, but not limited to, when the electrical signal output by the battery pack is 3 volts, the boost unit can convert the 3 volts to 5 volts. Here, the boost unit can be, but is not limited to, a power boost circuit well known in the art, and its specific structure and control principle will not be described in detail here.

[0061] The other end of the conduction control unit can be connected to the ground terminal to control the connection and disconnection of the circuit where one end of the secondary coil of the dual coil solenoid valve is located and the ground terminal. The conduction control unit can be, but is not limited to, the relay control circuit known in the art. Its specific structure and control principle will not be elaborated here.

[0062] The battery pack may include, but is not limited to, multiple disposable batteries connected in series, wherein the negative terminal of the last disposable battery in the battery pack may be connected to a ground terminal, and the positive terminal of the first disposable battery in the battery pack may be connected to the other end of the boost unit, but is not limited thereto.

[0063] In addition, the common terminal of a thermocouple can also be connected to the ground terminal. Figure 1 (Not shown in the image).

[0064] Understandably, when the timing or anti-dry-burning function of the gas stove affects the valve-closing control of the dual-coil solenoid valve, the circuit between one end of the secondary coil and the ground terminal of the dual-coil solenoid valve can be disconnected by the conduction control unit. Furthermore, the voltage control unit outputs the boosted electrical signal from the boost unit in pulse form to one end of the secondary coil of the dual-coil solenoid valve. The other end of the secondary coil is then connected to the ground terminal through the casing. Here, the electrical signal output from the positive terminal of the battery pack passes sequentially through the boost unit and the voltage control unit, and is output in pulse form to one end of the secondary coil of the dual-coil solenoid valve. Due to the physical characteristics of the thermocouple, the electrical signal output from the thermocouple to the main coil of the dual-coil solenoid valve has an opposite potential to the electrical signal on the secondary coil (or, the magnetic field generated by the main coil signal has opposite polarities to the magnetic field generated by the secondary coil signal), thus preventing the electromagnet from attracting the valve body.

[0065] It should be noted that when the user stops using the gas stove and needs to control the closing of the double-coil solenoid valve, the secondary coil one end of the double-coil solenoid valve and the ground end circuit can be disconnected by the on-off control unit, and the voltage control unit can also disconnect the voltage boosting unit and the series resistor circuit, that is, there is no electric signal on the secondary coil of the double-coil solenoid valve, at this time the output end of the thermocouple also stops outputting the electric signal to the primary coil one end of the double-coil solenoid valve, and then the electromagnet cannot generate the attraction force to the valve body due to the absence of the electric signal to generate the magnetic field.

[0066] When the double-coil solenoid valve is controlled to open the valve in zero seconds, the secondary coil one end of the double-coil solenoid valve and the ground end circuit can be turned on by the on-off control unit, and the voltage control unit can also disconnect the voltage boosting unit and the series resistor circuit, and the other end of the secondary coil of the double-coil solenoid valve is connected to the positive electrode of the battery pack at this time. Here, the electric signal output by the positive electrode of the battery pack is directly output to the other end of the secondary coil of the double-coil solenoid valve, and due to the simultaneous ignition of the igniter and the physical properties of the thermocouple, the electric signal output by the output end of the thermocouple to the primary coil one end of the double-coil solenoid valve has the same potential as the electric signal on the secondary coil (or the magnetic field generated by the primary coil electric signal has the same polarity as the magnetic field generated by the secondary coil electric signal), thereby causing the electromagnet to generate an attraction force to the valve body. After 5-8 seconds of power supply to the secondary coil of the double-coil solenoid valve, the on-off control unit disconnects the secondary coil one end of the double-coil solenoid valve and the ground end circuit, at this time the electric signal output by the output end of the thermocouple to the primary coil one end of the double-coil solenoid valve can make the electromagnet continuously generate an attraction force to the valve body.

[0067] It should be noted that whether the double-coil solenoid valve is controlled to close the valve or open the valve in zero seconds, the electric signal output by the battery pack needs to pass through the series resistor, and the impedance of the secondary coil of the double-coil solenoid valve is much lower than the resistance value of the series resistor, thereby causing the series resistor to have a great impact on the power consumption of the battery pack, and also easily causing the double-coil solenoid valve to fail to close the valve when the battery pack has a low power, thereby affecting the service life of the battery and the use experience of the gas stove.

[0068] Based on the above-mentioned technical defects, please refer to Figure 2 , Figure 2 The control device of the gas stove thermocouple double-coil solenoid valve is shown.

[0069] As Figure 2 shown, the control device of the gas stove thermocouple double-coil solenoid valve can include a control module and a direct current conversion module in addition to the thermocouple, double-coil solenoid valve and battery pack which are well known in the art, wherein:

[0070] The double-coil electromagnetic valve is provided with a main coil and a secondary coil to control the valve to close or open according to the electric signal output to the main coil and the electric signal output to the secondary coil. One end of the main coil of the double-coil electromagnetic valve is connected to the output end of the thermocouple, and the other end of the main coil is connected to the ground through the shell. One end of the secondary coil of the double-coil electromagnetic valve is connected to one end of the control module, and the other end of the secondary coil is connected to the ground through the shell.

[0071] The other end of the control module can be connected to one end of the DC conversion module to process the electric signal output by the DC conversion module to meet the valve closing control requirement or the valve opening control requirement of the double-coil electromagnetic valve.

[0072] The other end of the DC conversion module is connected to the positive electrode of the battery pack to process the electric signal output by the battery pack to meet the current requirement of the electric signal output to the secondary coil of the double-coil electromagnetic valve. Here, the DC conversion module can be but is not limited to a voltage reduction converter (i.e. DC / DC converter) known in the art, and can also be a special DC / DC conversion integrated circuit and a separate device control circuit. The specific structure and control principle will not be described here.

[0073] The battery pack can include but is not limited to a plurality of disposable batteries connected in series. The negative electrode of the last disposable battery in the battery pack can be connected to the ground, and the positive electrode of the first disposable battery in the battery pack can be connected to the other end of the DC conversion module.

[0074] It can be understood that when the double-coil electromagnetic valve is controlled to close due to the timing function or the dry burning prevention function of the gas stove, the DC conversion module can process the electric signal output by the battery pack to keep the electric potential of the processed electric signal unchanged by the control module, so as to output the processed electric signal to one end of the secondary coil of the double-coil electromagnetic valve. Due to the physical properties of the thermocouple, the electric signal output from the output end of the thermocouple to one end of the main coil of the double-coil electromagnetic valve is opposite in potential to the processed electric signal (or the magnetic field generated by the main coil electric signal is opposite in polarity to the magnetic field generated by the processed electric signal), which causes the electromagnet to lose the attraction force on the valve body.

[0075] It should be noted that when the user stops using the gas stove and needs to control the double-coil electromagnetic valve to close, the control module can disconnect the circuit between the DC conversion module and one end of the secondary coil of the double-coil electromagnetic valve, i.e. there is no electric signal on the secondary coil of the double-coil electromagnetic valve. At this time, the output end of the thermocouple also stops outputting the electric signal to one end of the main coil of the double-coil electromagnetic valve, which causes the electromagnet to lose the attraction force on the valve body due to the absence of the magnetic field generated by the electric signal.

[0076] When the zero-second fast suction opening valve control is performed on the double-coil electromagnetic valve, the DC conversion module can perform voltage reduction processing on the electrical signal output by the battery pack, so that the control module performs potential inversion processing on the voltage-reduced electrical signal, that is, changes the potential of the voltage-reduced electrical signal, and outputs the potential-inverted electrical signal to one end of the secondary coil of the double-coil electromagnetic valve. Due to the synchronization of the igniter and the physical characteristics of the thermocouple, the electrical signal output by the output end of the thermocouple to one end of the primary coil of the double-coil electromagnetic valve has the same potential as the potential-inverted electrical signal (or the magnetic field generated by the primary coil electrical signal has the same polarity as the magnetic field generated by the potential-inverted electrical signal), which further causes the electromagnet to generate an attractive force on the valve body. After the secondary coil of the double-coil electromagnetic valve is energized for 5-8 seconds, the control module disconnects the circuit between the DC conversion module and one end of the secondary coil of the double-coil electromagnetic valve. At this time, the electrical signal output by the output end of the thermocouple to one end of the primary coil of the double-coil electromagnetic valve can make the electromagnet continuously generate an attractive force on the valve body.

[0077] As an option of the embodiment of the present application, please refer to Figure 3 The control device for the thermocouple double-coil electromagnetic valve of the gas stove provided by the embodiment of the present application is shown in another effect diagram.

[0078] As Figure 3 shown, the control module can include a first on-off control unit, one end of the first on-off control unit is connected with one end of the secondary coil of the double-coil electromagnetic valve, and the other end of the first on-off control unit is connected with one end of the DC conversion module, so as to turn on or off the circuit between the electrical signal output by the DC conversion module and one end of the secondary coil of the double-coil electromagnetic valve. Here, the first on-off control unit can be but is not limited to a field effect transistor control circuit known in the art, and can also be a triode transistor control circuit, a thyristor control circuit, a digital analog switch circuit, a load switch control circuit, a relay control circuit or a photoelectric switch control circuit. The specific structure and control principle will not be described here.

[0079] The control module can further include a voltage inversion unit and a second on-off control unit, wherein:

[0080] One end of the voltage inversion unit is connected with one end of the secondary coil of the double-coil electromagnetic valve, and the other end of the voltage inversion unit is connected with one end of the second on-off control unit, so as to perform potential inversion processing on the electrical signal output by the DC conversion module, and output the potential-inverted electrical signal to one end of the secondary coil of the double-coil electromagnetic valve. Here, the voltage inversion unit can be but is not limited to a charge pump voltage inverter known in the art, and can also be an inverter or a negative voltage power converter. The specific structure and control principle will not be described here.

[0081] The other end of the second on-off control unit is connected with one end of the direct current conversion module, so as to turn on or turn off the circuit of the voltage reversing unit and the electric signal output by the direct current conversion module. Here, the second on-off control unit can be but is not limited to a field effect transistor control circuit, and can also be a silicon controlled rectifier control circuit, a digital analog switch circuit, a load switch control circuit, a relay control circuit or a photoelectric switch control circuit. The specific structure and control principle will not be described here.

[0082] In addition, the common end of the thermocouple can also be connected with the ground end.

[0083] In one or more of the above embodiments, the control device of the gas stove thermocouple double-coil electromagnetic valve can effectively reduce the additional power consumption of the battery due to the series resistance compared with the series resistance of the conventional control mode, and due to the low load consumption of the auxiliary coil, it can also avoid the failure of the double-coil electromagnetic valve when the battery pack has low power, thereby prolonging the service life of the battery and ensuring the use experience of the gas stove.

[0084] Next, please refer to Figure 4 , Figure 4 The overall flowchart of the control method of the gas stove thermocouple double-coil electromagnetic valve provided by the embodiment of the application is shown.

[0085] The control method of the gas stove thermocouple double-coil electromagnetic valve can be applied to the control device of the gas stove thermocouple double-coil electromagnetic valve mentioned in one or more of the above embodiments, as shown in Figure 4 The control method of the gas stove thermocouple double-coil electromagnetic valve can at least include the following steps:

[0086] Step 402: When detecting the monitoring signal of the gas stove, output a first control signal to the direct current conversion module, so that the direct current conversion module performs voltage reduction processing on the first electric signal output by the battery pack, and outputs the voltage reduction processed first electric signal to the control module by the direct current conversion module.

[0087] In the embodiment of the application, the execution body of the control method of the gas stove thermocouple double-coil electromagnetic valve can be but is not limited to a processing terminal of the gas stove. The processing terminal can be connected with the control device of the gas stove thermocouple double-coil electromagnetic valve mentioned above, so as to send a control signal to the control device of the gas stove thermocouple double-coil electromagnetic valve according to the signal sent by the user's operation or the preset automatic control program, so as to realize the valve control of the double-coil electromagnetic valve.

[0088] Specifically, when the processing terminal detects the monitoring signal of the gas stove, it indicates that the timing function or the anti-dry burning function set by the gas stove has an impact on the current use state of the gas stove, or it indicates that the user's valve rotation operation is received, that is, the user needs to use the gas stove, and then the first control signal can be output to the direct current conversion module, so that the direct current conversion module can perform voltage reduction processing on the first electric signal output by the battery pack according to the first control signal, and the first electric signal after voltage reduction processing can be output to the control module. Here, the first control signal can be understood as a level driving signal that changes periodically, for example, but not limited to, a level driving signal arranged in sequence according to a high level signal and a low level signal; the first electric signal can be the voltage normally output by the battery pack under the current power.

[0089] Step 404, outputting a second control signal to the control module, so that the control module can perform potential processing on the first electric signal after voltage reduction processing, and the control module can output the first electric signal after potential processing to one end of the auxiliary coil of the double-coil electromagnetic valve, and the double-coil electromagnetic valve can perform valve control processing according to the second electric signal received by the main coil and the first electric signal after potential processing.

[0090] Specifically, after outputting the first control signal to the direct current conversion module, the processing terminal can also output the second control signal to the control module at the same time, so that the control module can perform potential processing on the first electric signal after voltage reduction processing according to the second control signal. The potential processing method can be, but is not limited to, keeping the potential of the first electric signal after voltage reduction processing unchanged, or performing potential inversion processing on the first electric signal after voltage reduction processing, and the control module can output the first electric signal after potential processing to one end of the auxiliary coil of the double-coil electromagnetic valve. At this time, the double-coil electromagnetic valve can control the valve according to the second electric signal (that is, the electric signal generated by the thermocouple according to the heat generated by the flame) output by the output end of the thermocouple to one end of the main coil of the double-coil electromagnetic valve and the first electric signal after potential processing. For example, but not limited to, when the potential between the second electric signal and the first electric signal after potential processing is opposite (or the polarity of the magnetic field generated by the second electric signal is opposite to the polarity of the magnetic field generated by the first electric signal after potential processing), the electromagnet cannot generate attraction force on the valve body, thereby realizing valve closing control; when the potential between the second electric signal and the first electric signal after potential processing is the same (or the polarity of the magnetic field generated by the second electric signal is the same as the polarity of the magnetic field generated by the first electric signal after potential processing), the electromagnet can generate attraction force on the valve body, thereby realizing valve opening control.

[0091] As an option of the above embodiment, please refer to Figure 5 The overall flowchart of another control method of the gas stove thermocouple double-coil electromagnetic valve provided by the embodiment of the application is shown.

[0092] The control method of the gas stove thermocouple double-coil electromagnetic valve can be applied to the control device of the gas stove thermocouple double-coil electromagnetic valve mentioned in one or more of the above embodiments, wherein the control module includes a first on-off control unit, a voltage reversal unit, and a second on-off control unit, and the second control signal includes a circuit on signal and a circuit off signal. As shown in Figure 5 The control method of the gas stove thermocouple double-coil electromagnetic valve can at least include the following steps:

[0093] Step 502, when the monitoring signal of the gas stove is detected, output the first control signal to the DC conversion module to make the DC conversion module perform voltage reduction processing on the first electric signal output by the battery pack, and output the voltage reduction processed first electric signal to the control module by the DC conversion module.

[0094] Specifically, step 502 can refer to step 402, which will not be described in detail here.

[0095] Step 504, when the monitoring signal of the gas stove is a timing end signal, output the circuit off signal to the second on-off control unit to disconnect the circuit between the DC conversion module and the voltage reversal unit.

[0096] Specifically, when it is identified that the monitoring signal of the gas stove is a timing end signal issued by the timing function set by the processing terminal, it indicates that the valve closing control of the gas stove is needed, and then the circuit off signal can be output to the second on-off control unit by the processing terminal, so that the second on-off control unit disconnects the circuit between the DC conversion module and the voltage reversal unit. Here, the circuit off signal can be but not limited to a high-level signal or a low-level signal, and its type can be determined according to the circuit structure of the second on-off control unit, and is not limited thereto.

[0097] Step 506, output the circuit on signal to the first on-off control unit to turn on the circuit between the DC conversion module and one end of the auxiliary coil of the double-coil electromagnetic valve, and keep the potential of the voltage reduction processed first electric signal unchanged.

[0098] Specifically, after outputting the circuit-off signal to the second on-off control unit, the processing terminal can also output a circuit-on signal to the first on-off control unit at the same time, so that the first on-off control unit turns on the circuit between the DC conversion module and one end of the secondary coil of the double-coil electromagnetic valve, that is, the first electric signal output by the DC conversion module after voltage reduction can be directly output to one end of the secondary coil of the double-coil electromagnetic valve, and the potential of the first electric signal after voltage reduction remains unchanged. Here, when the second electric signal output by the output end of the thermocouple to one end of the primary coil of the double-coil electromagnetic valve is opposite to the potential between the first electric signal after voltage reduction, that is, the magnetic field generated by the second electric signal is opposite in polarity to the magnetic field generated by the first electric signal after voltage reduction, the electromagnet cannot generate an attractive force on the valve body, thereby realizing valve closing control. It can be understood that the circuit-on signal can be but is not limited to a high-level signal or a low-level signal, and the type thereof can be determined according to the circuit structure of the first on-off control unit, and is not limited thereto.

[0099] It can also be understood that when it is identified that the monitoring signal of the gas stove is a dry burning detection signal sent by the dry burning prevention function set by the processing terminal, it indicates that the valve closing control of the gas stove is needed, and at this time, the processing terminal controls the double-coil electromagnetic valve to close the valve. The way can refer to the above-mentioned embodiments, but will not be described here in detail.

[0100] As an option of the above-mentioned embodiments, please refer to Figure 6 The overall flowchart of another control method of a gas stove thermocouple double-coil electromagnetic valve provided by the embodiments of the present application is shown.

[0101] The control method of the gas stove thermocouple double-coil electromagnetic valve can be applied to the control device of the gas stove thermocouple double-coil electromagnetic valve mentioned in one or more of the above-mentioned embodiments, wherein the control module includes a first on-off control unit, a voltage reversal unit and a second on-off control unit, and the second control signal includes a circuit-on signal and a circuit-off signal. As Figure 6 shown, the control method of the gas stove thermocouple double-coil electromagnetic valve can at least include the following steps:

[0102] Step 602: When detecting the monitoring signal of the gas stove, output a first control signal to the DC conversion module, so that the DC conversion module reduces the voltage of the first electric signal output by the battery pack, and outputs the first electric signal after voltage reduction to the control module.

[0103] Specifically, step 602 can refer to step 402, which will not be described here in detail.

[0104] Step 604, when the monitoring signal of the gas stove is the valve pressing signal, outputting a circuit breaking signal to the first on-off control unit to break the circuit between the direct current conversion module and the auxiliary coil end of the double-coil electromagnetic valve.

[0105] Specifically, when it is identified that the monitoring signal of the gas stove is the valve pressing signal generated according to the valve rotation operation of the user, it indicates that the zero-second fast suction valve opening control of the gas stove is needed, and then the processing terminal can output a circuit breaking signal to the first on-off control unit to make the first on-off control unit break the circuit between the direct current conversion module and the auxiliary coil end of the double-coil electromagnetic valve. Here, the circuit structure of the first on-off control unit and the second on-off control unit is the same, and the circuit breaking signal can be but is not limited to a high-level signal or a low-level signal, and the type thereof can be determined according to the circuit structure of the second on-off control unit (i.e., the first on-off control unit), and is not limited thereto.

[0106] Step 606, outputting a circuit conducting signal to the second on-off control unit to conduct the circuit between the direct current conversion module and the voltage inversion unit, and performing potential inversion processing on the first electric signal after the voltage reduction processing by the voltage inversion unit.

[0107] Specifically, after outputting the circuit breaking signal to the first on-off control unit, the processing terminal can also output a circuit conducting signal to the second on-off control unit at the same time to make the second on-off control unit conduct the circuit between the direct current conversion module and the voltage inversion unit, so that the first electric signal after the voltage reduction processing output by the direct current conversion module is output to the voltage inversion unit, and the voltage inversion unit performs potential inversion processing on the first electric signal after the voltage reduction processing. Here, when the output end of the thermocouple outputs the second electric signal to the main coil end of the double-coil electromagnetic valve, the potential between the second electric signal and the first electric signal after the potential inversion processing is the same (or the magnetic field generated by the second electric signal and the magnetic field generated by the first electric signal after the potential inversion processing have the same polarity), the electromagnet can generate an attractive force on the valve body, thereby realizing the valve opening control.

[0108] It can be understood that the circuit conducting signal can be but is not limited to a high-level signal or a low-level signal, and the type thereof can be determined according to the circuit structure of the second on-off control unit (i.e., the first on-off control unit), and is not limited thereto.

[0109] Step 608, after a preset delay time, outputting a circuit breaking signal to the second on-off control unit to break the circuit between the direct current conversion module and the voltage inversion unit.

[0110] Specifically, since the gas stove is in a continuous ignition state, the output end of the thermocouple can continuously output the second electric signal to one end of the main coil of the double-coil electromagnetic valve, and after a preset delay time, in order to avoid continuous damage to the battery pack, the processing terminal can also output a circuit opening signal to the second on-off control unit, so that the second on-off control unit opens the circuit between the direct current conversion module and the voltage reversing unit, that is, the auxiliary coil of the double-coil electromagnetic valve does not receive the electric signal. At this time, since the output end of the thermocouple continuously outputs the second electric signal to one end of the main coil of the double-coil electromagnetic valve, the double-coil electromagnetic valve can generate a magnetic field according to the second electric signal, so that the electromagnet continuously generates an attractive force on the valve body, thereby realizing continuous opening control of the valve.

[0111] As another option of the above one or more embodiments, before outputting the first control signal to the direct current conversion module, it further comprises:

[0112] The third electric signal between the battery pack is obtained, and the third electric signal and the preset signal threshold are input into the deep learning model to obtain the duty cycle; wherein the deep learning model is trained by the preset signal threshold, at least two sample electric signals, and the sample duty cycle corresponding to each sample electric signal;

[0113] The first control signal is modulated according to the duty cycle.

[0114] Specifically, in order to guarantee the accuracy and reliability of the direct current conversion module in reducing the first electric signal, before outputting the first control signal to the direct current conversion module, the processing terminal can also obtain the third electric signal between the battery pack, which can be understood as the current remaining voltage of the battery pack, and input the third electric signal and the preset signal threshold into the deep learning model to obtain the duty cycle corresponding to the first control signal by model prediction. Here, the preset signal threshold can be understood as the voltage corresponding to the auxiliary coil of the double-coil electromagnetic valve when guaranteeing the current demand, for example but not limited to any voltage in the voltage interval of 0.3 volts to 0.5 volts, and the deep learning model can but not limited to refer to the neural network structure known in the art, which can be trained by the preset signal threshold, a plurality of sample electric signals, and the sample duty cycle corresponding to each sample electric signal.

[0115] Then, after obtaining the duty cycle corresponding to the first control signal, the processing terminal can modulate the first control signal according to the duty cycle, so as to output the first control signal to the direct current conversion module after the processing terminal detects the monitoring signal of the gas stove.

[0116] As another option of the above one or more embodiments, after outputting the second control signal to the control module, it further comprises:

[0117] When the difference between the absolute value of the second electric signal and the absolute value of the first electric signal after the potential processing exceeds the preset difference threshold, the absolute value of the second electric signal and the absolute value of the first electric signal after the potential processing are subjected to difference calculation processing;

[0118] The preset signal threshold is corrected according to the difference result to obtain a corrected signal threshold;

[0119] When the monitoring signal of the gas stove is detected again, a fourth electric signal between the battery pack is obtained, and a third control signal is modulated according to the fourth electric signal and the corrected signal threshold;

[0120] The third control signal is output to the direct current conversion module.

[0121] Specifically, in order to guarantee the valve closing efficiency of the double-coil electromagnetic valve when the next time the valve closing control of the gas stove is needed, when the difference between the absolute value of the second electric signal output by the output end of the thermocouple to one end of the main coil and the absolute value of the first electric signal after the potential processing exceeds the preset difference threshold, it indicates that the magnetic field generated by the electric signal after the potential processing cannot completely offset the magnetic field generated by the second electric signal, and then the absolute value of the second electric signal and the absolute value of the first electric signal after the potential processing are subjected to difference calculation processing by the processing terminal, and the preset signal threshold is corrected according to the difference result to obtain a corrected signal threshold. Here, when the corrected signal threshold is obtained, the processing terminal can but is not limited to multiply the difference result by a preset proportionality coefficient, and sum the product result with the preset signal threshold, and then obtain the corrected signal threshold, and the corrected signal threshold is also in the above-mentioned 0.3-0.5 volt voltage interval.

[0122] Then, after obtaining the corrected signal threshold, the processing terminal can also obtain a fourth electric signal between the battery pack when the monitoring signal of the gas stove is detected again, and can input the fourth electric signal and the corrected signal threshold into the above-mentioned deep learning model to modulate the corresponding third control signal according to the predicted duty cycle. Here, the fourth electric signal can be understood as the current remaining voltage after the battery pack outputs the first electric signal to the direct current conversion module; the third control signal can be understood as a level driving signal that changes periodically, for example but not limited to a level driving signal arranged in turn according to the high level signal and the low level signal.

[0123] Then, the processing terminal can output the modulated third control signal to the direct current conversion module, so that the above-mentioned control device of the gas stove thermocouple double-coil electromagnetic valve performs valve control again. The specific control method can be referred to the control method of the gas stove thermocouple double-coil electromagnetic valve mentioned in one or more embodiments, but will not be described here.
