The control method of the stove, the battery of the stove and the main control chip are connected with the power supply control module, the power supply control module can not only increase the low voltage output by the battery to the voltage suitable for the main control chip, but also store part of electric energy when the battery and the main control chip circuit are connected; after the user performs the fire starting operation through the ignition switch knob, the battery, the power supply control module and the main control chip circuit are connected, the power supply outputs a voltage of 0.3V-6V, the power supply control module converts the voltage output by the battery into a voltage of 3.3V and then distributes the voltage to the main control chip, so that the main control chip is powered on, and the power supply control module starts charging and storing part of electric energy at the same time.After the main control chip is powered on, the main control chip sends an ignition instruction while opening the power supply of the ignition pulse module, under the control of the ignition instruction, the valve control module controls the gas valve to open, and the ignition pulse module starts; after the stove is ignited, the main control chip closes the power supply of the ignition pulse module, and the ignition pulse module is closed, so that the stove is normally ignited; after the user performs the fire closing operation through the ignition switch knob, the battery is disconnected with the circuit of the main control chip, the power supply module supplies power for the main control chip by using the stored electric energy, so that the main control chip is delayed to be powered off; within the time period of the main control chip being delayed to be powered off, the main control chip controls the gas valve to be closed through the valve control module, so that the stove is turned off, and then the stove state information is sent to other devices through the wireless module; the other devices can be an APP installed on the user's mobile phone, or a wireless module of a range hood linked with the stove; after the wireless module of the range hood receives the stove state information sent by the wireless module of the stove, the range hood can adjust its state according to the stove state information, for example, timely shutdown or delayed shutdown.

[0023] The control method of the stove of the present application, after the user performs the fire closing operation through the ignition switch knob, the power supply control module supplies power for the main control chip in the case that the battery is disconnected with the circuit of the main control chip, so that the main control chip has time to send the stove state information to other devices through the wireless module, thereby avoiding the signal disconnection between the other devices and the stove.

[0024] The control method of the stove of the present application, the discharge time of the electric energy stored in the power supply control module is t1, the delay time of the main control chip being powered off is t2, t1≥t2, and the power supply control module is powered off after the main control chip sends the stove state information to other devices through the wireless module; the method for avoiding the signal disconnection between the stove and other devices is to make the main control chip of the stove send the stove state information through the wireless module and then be powered off; the delay time t2 of the main control chip being powered off is the shortest time required for the main control chip to send the stove state information through the wireless module, and the discharge time t1 of the electric energy stored in the power supply control module is the time during which the power supply control module can maintain the main control chip being powered on; only when t1≥t2, the main control chip has enough time to send the stove state information through the wireless module; in the case that t1>t2, the main control chip has sent the stove state information through the wireless module, and the electric energy stored in the power supply control module has not been completely discharged; at this time, the power supply control module can actively power off the main control chip; the signal for the power supply control module to actively power off the main control chip can come from the return signal of other devices, for example, after the range hood receives the signal sent by the wireless module of the stove, the range hood returns the signal through the wireless module of the range hood, and the wireless module of the stove receives the signal, so that the power supply control module powers off the main control chip.

[0025] The control method of the stove of the present application, the stove is also provided with a battery power detection module, after the user performs the ignition operation through the ignition switch knob, the battery, the power supply control module and the main control chip circuit are communicated, the power detection module detects the battery power and sends the detection result to the main control chip, when the power detection module detects that the battery power V>V1, the main control chip opens the power supply of the ignition pulse module and sends the ignition instruction at the same time, so that the valve control module controls the gas valve to open, and the ignition pulse module of the stove is started at the same time, the stove starts to ignite, after the stove completes the ignition, the main control chip closes the power supply of the ignition pulse module, the ignition pulse module is closed, and the stove normally ignites; when the power detection module detects that the battery power V≤V1, the main control chip does not open the power supply of the ignition pulse module and does not send the ignition instruction, the stove fails to ignite, the connection circuit of the battery and the power supply control module is disconnected, the power supply control module supplies power for the main control chip, so that the main control chip delays power-off, and the main control chip sends the information such as the state of the stove and the battery power to other equipment through the wireless module, wherein V1 is the minimum power at which the stove can normally ignite. The control method of the stove of the present application, after the user performs the ignition operation through the ignition switch knob, the main control chip accesses the circuit, the battery power detection module first detects the battery power V, only when the battery power is greater than the minimum power at which the stove can normally ignite, the main control chip will open the power supply of the ignition pulse module, and then send the ignition signal, so that the valve control module controls the gas valve to open and the ignition pulse module starts to ignite, after the ignition is completed, the ignition pulse module is closed. When the user performs the ignition operation through the ignition switch knob, the main control chip accesses the circuit, and the battery power detection module detects the battery power V≤V1, it indicates that the battery power is not higher than the minimum power at which the stove can normally ignite, if the ignition is performed at this time, the battery power will be released during the normal operation of the stove, when the battery power is released, the circuit connection between the battery and the main control chip is disconnected, and the ignition switch knob does not perform the ignition-off operation, the main control chip will be powered off after the power stored in the power supply control module is consumed, the main control chip cannot close the gas valve in time, and the stove cannot be turned off, therefore, when the main control chip accesses the circuit and the battery power detection module detects the battery power V≤V1, the main control chip does not open the power supply of the ignition pulse module and does not send the ignition instruction, the stove fails to ignite, the connection circuit of the battery and the power supply control module is disconnected, the power supply control module supplies power for the main control chip, so that the main control chip delays power-off, and the main control chip sends the information such as the state of the stove and the battery power to other equipment through the wireless module, when the other equipment is a smoke machine, the smoke machine will not perform the starting operation after receiving the signal.

[0026] Please refer to Figure 1The control method of the stove, the main control chip is provided with a timing module and a voltage detection module, the valve control module comprises an electromagnetic valve and a thermocouple, when the battery supplies power for the main control chip, the electromagnetic valve is connected to the circuit and receives the instruction of the main control chip to open or close the gas valve, the voltage detection module is used for detecting the voltage between the two ends of the thermocouple, after the stove is normally ignited, the main control chip enters a sleep state, the battery power detection module, the wireless module and the voltage detection module are in sleep, the circuit connected between the electromagnetic valve and the battery is disconnected, the thermocouple generates electric energy to supply power for the electromagnetic valve, and the timing module starts timing; every interval T, the main control chip is woken up, the ignition state of the stove and the power state of the battery are detected once through the voltage detection module and the battery power detection module, if there is no change, the main control chip enters the sleep state again, the battery power detection module, the wireless module and the voltage detection module are in sleep, and the timing module starts timing again.Or / and if the battery power decreases to V≤V1 within the time T of the main control chip sleeping, the battery power detection module detects that the battery power decreases to V≤V1 when the main control chip is woken up, the wireless module will be woken up, and the main control chip will send the battery power state to other devices through the wireless module. If the battery power always satisfies V>V1 within the time T of the main control chip sleeping, and the stove does not have an accidental fireout, the voltage detection module detects that the voltage across the thermocouple is normal, and the battery power detection module detects that the battery power is positive when the main control chip is woken up, and the main control chip enters the sleep state again, and the battery power detection module, the wireless module and the voltage detection module sleep, and the timing module restarts timing.

[0027] The control method of the stove of the application, if the wireless module is woken up after the timing module times T, if the battery power detection module detects that the battery power V≤V1, the wireless module is woken up, the main control chip sends the fireout instruction, the valve control module controls the gas valve to close, the main control chip sends the battery power state information to other devices through the wireless module, and continuously reminds the user of the low battery power. If the battery power decreases to V≤V1 within the time T of the main control chip sleeping, and the battery power state is detected by the battery power detection module after the main control chip is woken up, then the wireless module is woken up, the main control chip sends the fireout instruction, the valve control module controls the gas valve to close, the main control chip sends the battery power state information to other devices through the wireless module, so that other devices adjust their own state according to the fireout state of the stove, and the main control chip continuously reminds the user of the low battery power, so that the user resets the ignition switch knob.

[0028] The control method of the stove of the present application, the stove is also provided with an ignition switch knob detection module, if the timing module is timed T, the main control chip is awakened, if the voltage detection module detects that the voltage value of the two ends of the thermocouple is 0, and the ignition switch knob detection module detects that the ignition switch knob is in the fire-on state, then the main control chip judges that the valve control module closes the gas valve, the stove is extinguished, the main control chip awakens the wireless module and sends the data of the fire-on state of the stove to other devices through the wireless module and reminds the user to reset the switch knob. The accidental fire-off of the stove and the active fire-off of the user can be judged by the ignition switch knob detection module, when the stove is accidentally turned off, the valve control module closes the gas valve, but the position of the ignition switch knob is still in the fire-on state, but if the user turns off the stove through the ignition switch knob, the position of the ignition switch knob is in the fire-off state. When the main control chip is in sleep, if the user actively turns off the stove, the battery is disconnected from the circuit of the main control chip, the power supply control module supplies power to the main control chip, when a timing cycle ends, if the ignition switch knob detection module detects that the ignition switch knob is in the fire-off state, the main control chip sends the state information of the stove through the wireless module, then the power supply control module disconnects the power supply of the main control chip, and the stove enters a completely powered-off state; but if the stove is accidentally extinguished in a timing cycle, when a timing cycle ends, the voltage detection module detects that the voltage value of the two ends of the thermocouple is 0, and the ignition switch knob detection module detects that the ignition switch knob is in the fire-on state, then the main control chip judges that the valve control module closes the gas valve, the stove is extinguished, the main control chip awakens the wireless module and sends the data of the fire-on state of the stove to other devices through the wireless module and reminds the user to reset the switch knob.

[0029] In other embodiments, the stove also includes a gear detection module, when the stove is normally fired, if the user adjusts the firepower gear of the stove through the ignition switch knob, the gear detection module detects the firepower gear of the stove in real time and sends the detection result to the main control chip, and the main control chip sends the firepower gear information of the stove to other devices through the wireless module. The control method of the stove of the present application, the stove can be linked with other devices, for example, the stove can be linked with a smoke machine in real time, when the firepower gear of the stove changes, the gear detection module can detect the change of the firepower and send the detected change of the firepower to the main control chip, and the main control chip sends the change of the firepower of the stove to the smoke machine through the wireless module, and the smoke machine can adjust the air volume gear according to the firepower gear of the stove.

[0030] In the embodiment of the control method of the stove with the gear detection module, after the stove is normally ignited, the main control chip enters a sleep state, the wireless module sleeps, and the gear detection module detects the firepower gear of the stove in real time. When the gear detection module detects a change in the firepower gear of the stove, the main control chip is awakened, the gear detection module sends the detection result to the main control chip, the main control chip sends the firepower gear information of the stove to other devices through the wireless module, and after the firepower gear information is sent, the main control chip and the wireless module sleep again. When the main control chip sleeps, the gear detection module detects the firepower gear of the stove in real time. As long as the gear detection module detects a change in the firepower gear of the stove, the main control chip will be awakened and send the firepower gear change information to the range hood through the wireless module, so that the range hood can adjust the air volume gear at any time according to the firepower change. By arranging the gear detection module, the main control chip can sleep when the stove is normally ignited, thereby avoiding waste of battery power consumption, and the gear detection module monitors the firepower in real time, thereby avoiding missing of the change in the state information of the range hood by the main control chip.

[0031] In the embodiment of the control method of the stove with the gear detection module, the main control chip is provided with a timing module. After the stove is normally ignited, the main control chip enters a sleep state, the battery power detection module and the wireless module sleep, and the gear detection module and the timing module operate. The battery power detection module detects whether the battery power state satisfies V>V1 every time T. If yes, the battery power detection module continues to sleep, and if no, the wireless module and the main control chip are awakened. The main control chip sends a fire-off instruction, the valve control module controls the gas valve to close, the connection circuit of the battery and the power supply control module is disconnected, the power supply control module supplies power to the main control chip through the stored power, and the main control chip sends the stove state information to other devices through the wireless module within the delay power-off time of the main control chip. In the timing process of the timing module, the gear detection module detects the firepower gear of the stove in real time. The control method of the main control chip according to the battery power condition is the same as that in the above embodiment, which will not be repeated here. The difference lies in that, in this embodiment, because of the existence of the gear detection module, the gear detection module detects the firepower gear of the stove in real time in the timing process of the timing module, so that the change in the state information of the range hood can be avoided when the main control chip sleeps.
