It is to be understood that the specific embodiments described herein are merely illustrative of the application and not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts steps as a sequential process, many of the steps may be implemented in parallel, concurrently, or with other steps. Furthermore, the order of the steps may be rearranged.

The processes may correspond to methods, functions, procedures, subroutines, and the like.
The electronic flue-cured tobacco is electronic tobacco equipment which can bake tobacco leaves through a load module to generate smoke and achieve the effect of high temperature non-combustion, whether a user performs one-time smoking operation can be determined according to the resistance value of the load module, and then the number of smoking ports can be determined. However, as the resistance value of the load module is less in change, the misjudgment rate is increased by adopting the method for judging the resistance value of the load module, and the requirement for accurately controlling the electronic flue-cured tobacco still cannot be met. Therefore, the embodiment of the application provides an electronic flue-cured tobacco control scheme, which can effectively improve the accuracy of the number of the smoke extraction ports, and further improve the accuracy of controlling the electronic flue-cured tobacco.
Fig. 1 is a schematic flow chart of an electronic flue-cured tobacco control method according to an embodiment of the present invention, where the method may be performed by an electronic flue-cured tobacco control method apparatus, and the apparatus may be implemented by software and/or hardware, and may be generally integrated in a main control module of the electronic flue-cured tobacco control apparatus. As shown in fig. 1, the method includes:
s101, acquiring the temperature of the load module, and adjusting the temperature control parameter of a control signal according to the temperature, wherein the control signal is used for enabling the temperature control module to control the temperature of the load module.
The load module is a heating sheet for heating and baking tobacco leaves, and can heat according to the output current of the temperature control module.
The temperature control module is used for controlling the working state of the load module, can control the closing or starting of the load module, and can output corresponding current to the load module according to a control signal so as to control the working temperature of the load module.
The temperature of the load module in operation is different, so that the electronic flue-cured tobacco can be indicated to be in different use conditions. Illustratively, if the user is using the electronic flue-cured tobacco to perform a smoking operation, the load module will cure the tobacco in a warmed state so that the tobacco produces sufficient smoke to the user; if the user is in the neutral position between two smoking operations, the load module can adopt a lower temperature to reduce the smoke generated by tobacco leaves as the user does not need to smoke; wherein the operation of smoking a cigarette is an operation of smoking a cigarette by a user.
And adjusting the temperature control parameters of the control signals according to the temperature, so that the temperature of the load module can be controlled by the temperature control module within a preset temperature threshold value by the adjusted control signals, wherein the preset temperature threshold value can be a temperature range in which the temperature of the load module is kept to be enough to bake tobacco leaves, but overheat cannot occur. Along with the different temperatures of the load modules, the main control module needs to control the load modules to keep a constant temperature; for example, when the load module is used for baking tobacco leaves in a heating state, if the load module is heated continuously, the electronic flue-cured tobacco may burn or malfunction, so that the temperature of the load module needs to be controlled. The temperature of the load module can be obtained and compared with the preset temperature according to the temperature of the load module, and if the temperature of the load module is higher than the preset temperature, the temperature control parameter of the control signal is adjusted so that the temperature of the load module is lower than the preset temperature.
The temperature control parameter is an attribute parameter of the control signal, the temperature control parameter is changed, and the corresponding control signal can enable the temperature control module to control the temperature of the load module. The temperature control parameter may be at least one of an amplitude, a frequency, and a duty cycle of the control signal, for example.
Alternatively, the temperature of the load module may be determined by obtaining a resistance value of the load module, according to the resistance value of the load module.

For example, if the temperature parameter of the control signal changes, the temperature of the load module is reduced, that is, the temperature of the load module exceeds the preset temperature, the temperature of the load module is reduced by adjusting the temperature parameter of the control signal, so that the number of smoking mouths can be determined.
The determining the number of smoking openings may be performing accumulation processing on the number of smoking openings, for example, if the number of smoking openings is determined once, adding one to the number of smoking openings, counting the number of smoking openings of a user in the process of using the electronic flue-cured tobacco this time, and further controlling the electronic flue-cured tobacco according to the number of smoking openings.
Optionally, after determining the number of smoking mouths according to the change of the temperature control parameter of the control signal, the method further comprises:
and if the number of the smoking openings reaches the preset times, closing the load module.
If the number of the smoking openings reaches the preset times, the tobacco leaves in the electronic flue-cured tobacco are cured for a plurality of times, basically, a user can be reminded of replacing the tobacco leaves, and the heating function of the electronic flue-cured tobacco can be closed by closing the load module, so that the tobacco leaves in the electronic flue-cured tobacco are not cured, and the smoking taste of the user is ensured.
The method for controlling the electronic flue-cured tobacco comprises the steps of obtaining the temperature of a load module, and adjusting temperature control parameters of control signals according to the temperature, wherein the control signals are used for enabling the temperature control module to control the temperature of the load module; and determining the number of smoking mouths according to the change of the temperature control parameter of the control signal. Through adopting above-mentioned technical scheme, can take notes the cigarette mouth number of user to according to the cigarette mouth number to the stoving process of electron flue-cured tobacco is controlled, improves the accuracy of the stoving of electron flue-cured tobacco, optimizes user's experience.

s111, acquiring the temperature of the load module.
The specific embodiments may refer to the related descriptions above, and will not be described herein.
And S112, if the temperature is greater than the set temperature, performing first adjustment on the temperature control parameter of the control signal so as to enable the control signal to reduce the temperature of the load module.
And S113, if the temperature is smaller than the set temperature, performing second adjustment on the temperature control parameter of the control signal so as to enable the control signal to increase the temperature of the load module.
And S114, if the temperature is equal to the set temperature, maintaining the temperature control parameter of the control signal.
The set temperature may be a temperature value or a temperature interval. If the set temperature is a temperature interval, if the temperature is greater than the maximum value of the temperature interval, determining that the temperature is greater than the set temperature; if the temperature is smaller than the minimum value of the temperature interval, determining that the temperature is smaller than a set temperature; and if the temperature is within the temperature range, determining that the temperature is equal to the set temperature.
By judging whether the temperature is greater than or less than the set temperature and correspondingly adjusting the temperature control parameters of the control signals, the temperature of the load module can be kept in a constant temperature range, and the load module of the electronic flue-cured tobacco can be effectively in the set temperature.
And maintaining the temperature control parameters of the control signals, namely not adjusting the temperature control parameters of the control signals, and maintaining the temperature control parameters of the control signals unchanged. If the temperature is equal to the set space, the temperature of the load module is exactly in the required temperature range, and the temperature parameter of the control signal is kept unchanged, so that the temperature of the load module can be kept in a constant temperature range.
The first adjustment and the second adjustment are respectively different adjustments of temperature control parameters of control signals so as to respectively reduce the temperature of the load module and increase the temperature of the load module.
Alternatively, the control signal may be a PWM (Pulse Width Modulat ion, pulse width modulated) signal; the temperature control parameter is duty ratio, the first adjustment is to reduce the duty ratio, the second adjustment is to increase the duty ratio, and if the temperature is equal to the set temperature, the duty ratio output of the PWM signal is kept unchanged. The proportion of the switch of the MOS tube is controlled by the duty ratio of the PWM signal, so that the MOS tube outputs different currents to the load module, and the effect of controlling the temperature of the load module is achieved.
The temperature control module can be a MOS (metal oxide semiconductor, metal-oxide-semiconductor) tube, and the load module is connected with a power supply through the MOS tube. The MOS tube can be conducted by increasing the duty ratio of the control signal, so that a power supply can supply power to a load module, and the load module can continue to heat; the MOS tube can be disconnected by reducing the duty ratio of the control signal, and then the load module cannot continue to heat, so that the temperature can be reduced.
S115, determining the number of smoking mouths according to the change of the temperature control parameter of the control signal.
Wherein, the change of the temperature control parameter of the control signal comprises the first adjustment of the temperature control parameter of the control signal and/or the second adjustment of the temperature control parameter of the control signal, so that the number of smoking mouths can be determined according to the number of the first adjustment and/or the number of the second adjustment. The specific embodiments may refer to the related descriptions above, and will not be described herein.
Alternatively, determining the number of smoking openings from a change in a temperature control parameter of the control signal may be performed by:
and if the number of times of the first adjustment of the temperature control parameters of the control signals is larger than or equal to the preset number of times, accumulating the number of smoking openings.
The temperature of the load module is obtained continuously, and then the temperatures of a plurality of load modules can be obtained; for example, the temperature of the load module may be acquired every 0.3 seconds. Because the operation of smoking a cigarette by a user may last for 2-3 seconds when the user uses the electronic flue-cured tobacco, it may be determined whether the user performs a smoking operation by determining that the number of times of performing the first adjustment of the temperature control parameter is greater than or equal to a preset number of times.
If the number of times of the first adjustment of the temperature control parameter of the control signal is greater than or equal to the preset number of times, the temperature of the load module is continuously higher than the set temperature, and at least the temperature of the preset number of times among the collected temperatures of the load module is greater than the set temperature, it can be determined that the user has performed one smoking operation, and the number of smoking openings can be accumulated.
Optionally, the number of times of continuously performing the first adjustment on the temperature control parameter of the control signal is greater than or equal to a preset number of times, and then the number of smoking openings is accumulated. The accumulating process may be to add one to the number of smoking openings, that is, the number of times of continuously performing the first adjustment on the temperature control parameter of the control signal detected each time is greater than or equal to the preset number of times, and then add one to the number of smoking openings.
By way of example, by continuously reading the temperature control parameter and comparing the temperature control parameter with the temperature control parameter read last time, whether the temperature control parameter is increased or decreased can be determined, and whether the temperature control parameter is subjected to the first adjustment and whether the number of the first adjustment is greater than or equal to the preset number of times can be determined. For example, if the parameters of the first adjustment of the temperature control parameters are greater than or eight times, it may be determined that the user performs one smoking operation, and then the number of smoking openings may be accumulated and increased by one.
According to the embodiment of the application, whether the user performs one-time smoking operation can be determined according to the number of times of first adjustment of temperature reduction of the load temperature, and then the number of smoking ports of the user can be determined and recorded, so that the baking process of the electronic flue-cured tobacco is controlled according to the number of the smoking ports, the baking accuracy of the electronic flue-cured tobacco is improved, and the user experience is optimized.

After the load voltage of the load module is acquired, the main control module can control the first triode to be disconnected, and the temperature control module is controlled to be conducted by outputting a low-level PWM signal, so that the load module can continue to heat.
The load voltage of the load module, namely the voltage of the first end of the first resistor R15, and the load voltage AD can be collected by the main control module through the second end of the second resistor R14 and the second end of the third resistor R17. As shown in fig. 4, the pin 16 of the master control module is connected to the second end of the second resistor R14, and the pin 20 of the master control module is connected to the second end of the third resistor R17.
The first power supply is grounded through the first resistor R15 and the load module, so that the first resistor R15 and the load module are divided in series, and the voltage vbat+ of the first power supply is loaded on the second resistor and the load module.

The load voltage AD is collected by the main control module, the resistance R2 of the first resistor R15 is known, and the voltage vbat+ of the first power supply is known, so that the resistance R1 of the load module can be calculated according to ad= (R1/(r1+r2)) × vbat+. And further, the temperature of the load module can be determined according to the resistance value of the load module.
The load module is made of thermistor materials, so that the load module can form a resistance corresponding to temperature, and the temperature of the load module can be converted according to the resistance of the load module by collecting the resistance of the load module.
Because the resistance of the load module is generally smaller, if the resistance of the load module is directly collected to determine the temperature of the load module, a larger error may be caused, so that the voltage value of the load module is improved by introducing the series voltage division between the first resistor R15 and the load module, the accuracy of the collected load voltage of the load module can be improved, and the accuracy of the collection of the temperature of the load module is further improved.
