When the gas stove is ignited, the hand-push type electromagnetic valve can be pushed open by the push rod in the valve body, so that the electromagnetic force is not required to be absorbed; the self-priming electromagnetic valve needs a larger attraction electromagnetic force to attract the armature to open the fuel gas channel, so that a larger attraction current needs to be provided.
Currently, gas cookers using self-priming electromagnetic valves basically use a pair of dry batteries to supply power to the gas cookers. As is well known, dry batteries have a certain internal resistance, and as the amount of electricity is released, the internal resistance becomes larger, and particularly when a larger current is provided, the voltage occupied by the internal resistance is higher, resulting in a decrease in load voltage. After the dry battery is used to a certain extent, the voltage of the load end of the dry battery is pulled lower than the working voltage of the MCU of the controller during the action and suction of the self-suction electromagnetic valve, so that the MCU is powered off and does not work. Because the controller MCU can not work normally and needs to replace a new battery, the residual 30% -40% of electric quantity of the primary battery can not be fully utilized to cause the pressure of resource waste and environmental pollution, and meanwhile, the frequency of battery replacement of a user is improved, and the use experience is reduced.

Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
Example 1
The embodiment provides a control method for power supply of a gas stove battery, as shown in fig. 1, the gas stove comprises a controller 10, a micro-control unit 11, a first battery 20 and a second battery 30, wherein the first battery 20 is used for providing power for the controller 10 and other power consumption modules of the gas stove, and the second battery 30 is used for providing power for the micro-control unit 11; as shown in fig. 2, the gas range battery power supply control method includes the steps of:
s1, acquiring a voltage value of the first battery 20.
S2, determining a power supply mode of the micro control unit 11 according to the voltage value of the first battery 20, wherein the power supply mode includes: a single battery power supply mode and a double battery power supply mode, wherein the single battery power supply mode is as follows: the micro control unit 11 is powered by the first battery 20 alone, and the dual battery power supply mode is: the first battery 20 and the second battery 30 simultaneously supply power to the micro control unit 11.
The gas stove is generally internally provided with a controller and a micro-control unit for controlling the gas stove, and a battery for supplying power to the gas stove controller, the self-priming electromagnetic valve, the timer and other energy-consuming components. The mode of supplying power to the micro control unit of the gas stove can be determined by the voltage value of the first battery 20, and the starting of the second battery 30 can be further controlled, so that the following steps are realized: when the self-priming electromagnetic valve and the high-voltage pulse ignition work simultaneously, the second battery 30 is started to provide enough power supply for the micro-control unit 11 of the gas stove under the condition that the first battery 20 cannot ensure the normal work of the controller.
Further, the step of obtaining the 20 voltage value of the first battery includes the steps of:
the first voltage value of the first battery 20 stored in the controller is read before the ignition signal is obtained for the ignition operation.
In an actual application scenario, the first voltage value of the first battery 20 is stored in the storage unit of the controller, and the voltage value is an obtained battery voltage value after the ignition operation of the gas stove is completed last time, so that the power supply capability of the first battery for all energy-consuming components of the gas stove when the gas stove performs the ignition operation last time can be fully reflected.
Further, as shown in fig. 3, the step of determining the power supply mode of the micro control unit 11 according to the first voltage value of the first battery 20 includes the steps of:
comparing the first voltage value of the first battery 20 with a preset threshold value; the preset threshold range may be 2.3V-2.4V, for example, the operating voltage of the MCU is 1.8V, and then, when the battery is about 2.3V, the instantaneous voltage drop value of the voltage at the time of the electromagnetic valve and the high-voltage discharge is about 0.5V, and at this time, the voltage of the battery supplied to the MCU is just 1.8V. The voltage of the battery is different in different stages, and the instantaneous voltage drop value of the voltage is different when the electromagnetic valve and the high-voltage discharge.
When the first voltage value of the first battery 20 is greater than the preset threshold value, determining that the power supply mode of the micro control unit 11 is a single battery power supply mode; when the first voltage value of the first battery 20 is smaller than the preset threshold value, it is determined that the micro control unit 11 power supply mode is a dual battery power supply mode.
In a specific embodiment, when it is determined that the first battery cannot provide power for all energy-consuming components of the gas stove at the same time, and the self-priming battery valve is sucked to cause the micro-control unit 11 to lose power and reset, a dual-battery power supply mode is started, and the second battery provides a supplementary power for the micro-control unit 11, so that the micro-control unit 11 is ensured to work normally.
Specifically, after the step of determining that the power supply mode of the micro control unit 11 is the dual battery mode when the first voltage value is smaller than the preset threshold value, the method further includes:
after the ignition operation is performed, the second voltage value of the first battery 20 is acquired, and the second voltage value of the first battery 20 is substituted for the first voltage value of the first battery 20.
After the ignition operation is completed, the micro control unit 11 power supply mode is switched to the single cell power supply mode.
When the self-priming electromagnetic valve of the gas stove is in action suction, the required current is maximum and reaches 300-500mA, and generally, the battery can provide enough power supply for all energy consumption components when the gas stove normally works as long as the self-priming electromagnetic valve can be in smooth suction.
After the ignition operation of the gas stove is completed, a battery voltage value which can fully reflect the power supply capacity of the battery in the operation is obtained, and the battery voltage value is written into a storage unit in the controller to replace original data, and is used as a new first voltage value of the first battery 20 to provide a basis for the next judgment. After the ignition operation of the gas range is completed, the power supply is switched to be provided by the first battery 20, so that the residual power of the first battery 20 can be effectively utilized.
Specifically, the second voltage value of the first battery 20 may be obtained by:
after the ignition operation is completed, the actual voltage value of the first battery 20 is acquired; and calculating a difference between the actual voltage value of the first battery 20 and a preset battery voltage drop value, wherein the obtained difference is a second voltage value of the first battery 20.
In the present embodiment, the battery voltage drop value is a voltage drop value measured when the self-priming solenoid valve is operated to draw in and the high-voltage pulse discharge is operated simultaneously with the first battery 20 at different voltages, and the value is written into the controller 10 and called.
Specifically, the second voltage value of the first battery 20 may also be:
during the ignition operation of the gas stove, when the self-suction electromagnetic valve is in suction and the high-voltage pulse discharge is operated simultaneously, the obtained voltage average value of the first battery 20 is obtained.
Specifically, the second voltage value may be obtained by the above two methods, the second voltage value=the actual voltage value obtained after the completion of ignition-the voltage drop value; or a second voltage value = minimum actual voltage value. The minimum actual voltage value may be obtained by automatically reading a series of voltage values by the micro control unit 11 when the solenoid valve and the high voltage discharge are simultaneously operated, and then calculating an average value as a final minimum actual voltage value. Specifically, the micro control unit 11 may acquire voltage values once every 50ms, acquire 9 to 10 voltage values in total, and then average. In practice, the 9-10 data may be recorded first, and then the average value may be calculated when the resources of the micro control unit 11 are relatively rich, and then the operation of replacing the first voltage value may be performed.
In one embodiment, the time for actuation of the self-priming solenoid valve is 500ms.
The following description is made in connection with the specific implementation procedure:
after the micro control unit 11 receives the ignition operation signal, starting a gas stove battery power supply control method, firstly reading a first voltage value of a first battery 20 stored in a storage unit, comparing the first voltage value with a preset threshold value to judge a power supply mode, wherein the range of the preset threshold value can be 2.3V-2.4V, and when the micro control unit 11 judges a double-battery power supply mode, the micro control unit 11 controls a switch for conducting a second battery 30 to be closed, and the second battery 30 supplies power to the micro control unit 11; thereafter, the micro control unit 11 performs an ignition operation, because the micro control unit 11 is supplied with power from the second battery 30 having a sufficient amount of power, the problem of insufficient power supply capacity of the first battery 20 when the self-priming electromagnetic valve is operated to be engaged and the high-voltage pulse discharge is simultaneously operated can be solved; after the ignition operation is performed, the voltage value of the first battery 20 is acquired again and is used as a basis for judging the power supply mode next time; after the ignition operation is completed, the micro control unit 11 controls the switch for conducting the second battery 20 to be turned off, and the micro control unit 11 is powered by the first battery 20, so that the residual electric quantity of the first battery 20 can be fully utilized; meanwhile, the micro control unit 11 has low power consumption, and the second battery 30 supplies power to the micro control unit 11 for a short time, so the second battery 30 does not need to have a large capacity, and can be miniaturized, thereby being beneficial to the structural design of the gas stove and reducing the cost.
