The electronic cigarette is provided with a heating body for baking tobacco, the resistance value of the heating body is in a direct proportion relation with the temperature, the heating body is connected with a temperature detection module, and the temperature detection module is used for detecting the temperature of the heating body. Certainly the electron cigarette still can include resistance detection module, and resistance detection module is used for detecting the resistance of heat-generating body.
As shown in fig. 1, an embodiment of the present application provides a method for determining the number of smoking openings of an electronic cigarette, including:
and S11, acquiring the sum of the variation of the characteristic parameters of the heating element of each sampling point in the first sampling period to obtain a first total variation.
Usually, when the user does not smoke, the temperature or the resistance value of the heating element is in a relatively stable stage, such as the temperature is kept at 300 ℃, the positive and negative fluctuation is 0.3 ℃ or the resistance value fluctuation is +/-1 m omega milliohm.
When a user smokes, the balance at the moment can be broken, so that the temperature or the resistance value of the heating body is in a fluctuation state. Wherein the temperature or resistance value of the heating element has a certain waveform.
The variation of the characteristic parameter is the difference between the current characteristic parameter and a preset parameter threshold.
In one embodiment, the first sampling period may be set according to an empirical value, or may be obtained by dynamically adjusting the temperature and the resistance value.
For example, the first total change amount is obtained by summing or integrating the change amounts of the characteristic parameters of the heat-generating body in the first sampling period.
In one embodiment, the characteristic parameter includes a resistance value of the heat generating body or a temperature of the heat generating body.
And S12, acquiring the sum of the variation of the characteristic parameters of the heating element of each sampling point in the second sampling period to obtain a second variation total.
Wherein a time difference between the first sampling period and the second sampling period is within a preset time length range; the preset time length range is specifically set according to an empirical value, and is usually smaller, for example, 100 ms. In one embodiment, the second sampling period may be set according to an empirical value, or may be obtained by dynamically adjusting the temperature and the resistance value.
For example, the second total change amount is obtained by summing or integrating the change amounts of the characteristic parameters of the heating element in the second sampling period.
And S13, acquiring the difference between the first total change amount and the second total change amount.
And S14, determining the number of the primary smoking openings when the difference value is within the preset threshold range.
For example, if the user smokes, the difference value is within the preset threshold range, and if the user does not smoke, the difference value is beyond the preset threshold range. When the difference value is beyond the preset threshold range, the step S11 may be executed again.
The method for judging the number of smoking openings of the electronic cigarette obtains a first total variation amount by obtaining the sum of variation amounts of characteristic parameters of a heating element at each sampling point in a first sampling period; acquiring the sum of the variation of the characteristic parameters of the heating element of each sampling point in the second sampling period to obtain a second variation total; obtaining a difference between the first total amount of change and the second total amount of change; when the difference value is within a preset threshold range, determining the number of the primary smoking openings; the difference value of the total change amount in the two sampling periods is compared with the preset threshold range, so that the accuracy of judging the number of smoking openings is improved.
As shown in fig. 2, an embodiment of the present application further provides a method for determining the number of smoking openings of an electronic cigarette, including:
s101, obtaining the sum of the variation of the temperature of the heating element at each sampling point in the first sampling period to obtain a first total variation.
The temperature variation is the difference between the current temperature and a preset temperature threshold; as shown in fig. 3 and 4, the abscissa in fig. 3 and 4 represents time, and the ordinate represents temperature. Fig. 3 is a waveform diagram showing the temperature of the heating element when the user does not smoke, and the temperature of the heating element is in a relatively stable stage, such as the temperature is maintained at 300 ℃ and the positive and negative fluctuation is 0.3 ℃.
FIG. 4 is a waveform diagram showing the temperature of the heating element when a user smokes.
For example, the difference between the current temperature of each of the sampling points c1 to c6 in the first sampling period B1 and the preset temperature threshold is obtained, and the difference is summed to obtain the first total variation amount.
In some embodiments, the first sampling period may be obtained by dynamic adjustment according to the temperature or the resistance, specifically referring to steps S105 to S107.
S102, obtaining the sum of the variation of the temperature of the heating element at each sampling point in the second sampling period to obtain a second variation total.
For example, the difference between the current temperature of each of the sampling points c7 to c12 in the second sampling period B2 and the preset temperature threshold is obtained, and the difference is summed to obtain the second total variation amount. The preset temperature threshold and the preset parameter threshold are obtained in the same manner, which is specifically referred to above and will not be described herein again.

S103, acquiring a difference value between the first change total amount and the second change total amount.
And S104, determining the number of the primary smoking openings when the difference value is within the preset threshold range.
For example, if the user smokes, the difference value is within the preset threshold range, and if the user does not smoke, the difference value is beyond the preset threshold range. When the difference exceeds the preset threshold range, the step S101 may be executed again. The preset threshold range is a temperature range.
In some embodiments, the method further comprises:
s105, obtaining a difference value between the current temperature of the heating element and a preset temperature threshold value at each moment in two adjacent moments, and respectively obtaining a first difference value and a second difference value.
S106, obtaining the ratio of the first difference value to the second difference value.
Wherein the ratio may be an absolute value of a ratio of the first difference and the second difference.
S107, setting the first sampling period or the second sampling period according to the ratio and a preset period.
Such as the period of the temperature waveform.
In some embodiments, the step S107 includes:
s1071, when the ratio is larger than a preset ratio threshold, the first sampling period and the second sampling period are both smaller than the preset period.
S1072, when the ratio is smaller than or equal to the preset ratio threshold, the first sampling period and the second sampling period are both larger than the preset period.
For example, the preset ratio threshold may be 1, when the absolute value of the ratio of the first difference to the second difference is greater than 1, the sampling period at this time is 1/4 of the period of the temperature waveform, and when the absolute value of the ratio of the first difference to the second difference is less than or equal to 1, the period time is greater than the preset period, which may be specifically set according to the requirement.
The setting manner of the second preset period is similar to that of the first preset period, and is not described herein again.
In some embodiments, the preset parameter threshold is obtained by:
s111, respectively obtaining a difference value between the current characteristic parameter of the heating element at each time point in the preset duration and the preset target parameter and a variance value between the current characteristic parameter of the heating element at each time point and the preset target parameter to obtain a plurality of data sets, wherein each data set comprises a third difference value and a variance value.
Wherein the third difference is a difference between the current characteristic parameter of the heating element at each time point and the preset target parameter.
The preset duration is set according to the empirical value, and the preset target parameter is the optimal temperature or the optimal resistance value of the heating body during smoking.
S112, selecting a first reference data group and a second reference data group from the plurality of data groups; the first reference data group is a data group corresponding to the minimum value of the third difference and the variance in the plurality of data groups; the second reference data group is a data group corresponding to the maximum third difference and the maximum variance in the plurality of data groups.
For example, a data group in which the third difference and the variance are simultaneously the minimum values among the plurality of data groups is set as the first reference data group, and a data group in which the third difference and the variance are simultaneously the maximum values among the plurality of data groups is set as the second reference data group.
S113, obtaining the preset parameter threshold according to the third difference value in the second reference data group and the third difference value in the first reference data group.
In an embodiment, in order to further improve the accuracy of the determination, the step of obtaining the preset parameter threshold according to the third difference in the second reference data group and the third difference in the first reference data group includes:
s1131, obtaining a difference value between the third difference value in the second reference data group and the third difference value in the first reference data group to obtain a set difference value.
S1132, acquiring the preset parameter threshold according to the set difference and the third difference in the first reference data group.
For example, in one embodiment, the variance is 50 with the third difference in the first reference data set being 10. The third difference in the second reference data set is 100, and the variance is 200, for example, when the set difference is equal to 90, the preset parameter threshold is equal to half of the set difference plus the minimum third difference (10), so as to obtain the preset threshold, which is equal to 55. The preset parameter threshold comprises a preset temperature threshold or a preset resistance threshold.
The method for judging the number of smoking openings of the electronic cigarette obtains a first total change amount by obtaining the sum of the variation amounts of the temperatures of the heating elements at each sampling point in a first sampling period; acquiring the sum of the variation of the temperature of the heating element of each sampling point in the second sampling period to obtain a second variation total; obtaining a difference between the first total amount of change and the second total amount of change; when the difference value is within a preset threshold range, determining the number of the primary smoking openings; the difference value of the total change amount of the temperature in the two sampling periods is compared with the preset threshold range, so that the accuracy of judging the number of the smoking openings is improved.
As shown in fig. 5, an embodiment of the present application further provides a method for determining the number of smoking openings of an electronic cigarette, including:
s201, obtaining the sum of the variable quantities of the resistance values of the heating elements at each sampling point in the first sampling period to obtain a first total variable quantity.
The variable quantity of the resistance value is a difference value between the current resistance value and a preset resistance value threshold value; when the user does not smoke, the resistance value of the heating element is in a relatively stable stage, and when the user smokes, the resistance value of the heating element fluctuates greatly.
For example, referring to fig. 4, the difference between the current resistance value of each of the sampling points c1 to c6 in the first sampling period B1 and the preset resistance value threshold is obtained, and the difference is summed to obtain the first total variation amount.
The specific obtaining mode of the preset resistance value threshold is the same as the obtaining mode of the preset parameter threshold.
In one embodiment, the current resistance value of the heating element is the resistance value detected by the resistance value detection module.
In another embodiment, in order to improve the accuracy of the detection, the current resistance value is obtained by compensating the current measured resistance value of the heat generating body according to the current temperature of the heat generating body.
For example, the current temperature corresponds to a compensation factor, and the resistance value detected by the resistance value detection module is compensated according to the compensation factor to obtain the current resistance value. In one embodiment, the current resistance value is equal to the compensation factor multiplied by the resistance value detected by the resistance value detection module, but the compensation method is not limited thereto.
In other embodiments, the current resistance value may also be obtained by a table lookup. For example, according to a preset list of the temperature and the resistance value, the resistance value corresponding to the current temperature of the heating element is searched, and the current resistance value is obtained.
In some embodiments, the first sampling period may be obtained by dynamic adjustment according to the temperature or the resistance, specifically referring to steps S105 to S107.
S202, obtaining the sum of the variable quantities of the resistance values of the heating elements at each sampling point in the second sampling period to obtain a second variable total quantity.
For example, the difference between the current resistance value of each of the sampling points c7 to c12 in the second sampling period B2 and the preset resistance value threshold is obtained, and the difference is summed to obtain the second total variation amount. Wherein the number of sampling points in the first sampling period and the second sampling period are equal, in an embodiment, in order to reduce complexity, the first sampling period and the second sampling period may be equal.
S203, acquiring a difference value between the first change total amount and the second change total amount.
And S204, determining the number of the primary smoking openings when the difference value is within the preset threshold range.
For example, if the user smokes, the difference value is within the preset threshold range, and if the user does not smoke, the difference value is beyond the preset threshold range. When the difference exceeds the preset threshold range, the step S201 may be executed again. The preset threshold range is a resistance range.
The method for judging the number of smoking openings of the electronic cigarette obtains a first total change amount by obtaining the sum of the variation amounts of the resistance values of the heating elements at each sampling point in a first sampling period; acquiring the sum of the variable quantities of the resistance values of the heating elements at each sampling point in the second sampling period to obtain a second variable total quantity; obtaining a difference between the first total amount of change and the second total amount of change; wherein a time difference between the first sampling period and the second sampling period is within a preset time length range; when the difference value is within a preset threshold range, determining the number of the primary smoking openings; the difference value of the total change amount of the resistance values in the two sampling periods is compared with the preset threshold range, so that the accuracy of judging the number of the smoking openings is improved.
In one embodiment, the above method is described in detail below with reference to specific embodiments,
when the user does not smoke, the temperature or the resistance value of the heating element is in a relatively balanced stage, namely a relatively stable temperature stage, for example, the temperature is kept at 300 ℃, the positive and negative fluctuation is 0.3 ℃ or the resistance value fluctuation is +/-1 m omega milliohm, namely a stable state stage. When the system is disturbed by the outside, such as when a user smokes, the balance at the moment can be broken, and the whole system is in a fluctuation state. If the temperature control system of the electronic cigarette is good, the temperature can quickly return to the steady-state stage, but a relatively large fluctuation still exists, namely the difference between the actual value and the ideal value is plus or minus 5 data bits (the resistance value also fluctuates). In one embodiment, the temperature control system controls or adjusts the temperature of the heating element by a PID method, which is a method of controlling the temperature according to the proportion (P), the integral (I), and the derivative (D) of the deviation.
Therefore, the temperature or the resistance value in the current period of time is sampled, the difference is made between the real-time sampling value of each sampling point and an ideal value, for example, the ideal value of the temperature is 300 ℃, the sampling temperature is 299 ℃, the temperature difference is 1 at the moment, the variation is recorded as 1, and the method is also suitable for the resistor of the heating element, such as the fluctuation of 3m omega. And recording the temperature difference or the resistance difference in a time period, and summing the temperature difference or the resistance difference, namely performing integration processing, wherein the recording time is relatively fast, 10 times or 100 times of recording within 1s, and the recording times are not limited, so that the deviation between the actual temperature control difference and the ideal value is obtained.
And respectively recording data of two time periods, namely recording two groups of integral data (including integral data when the user does not perform smoking action when the user does not change and integral data when the user performs smoking action when the user changes), subtracting the integral data in the current time period from the integral data in the previous time period, and determining the number of the smoking openings as the number of the smoking openings when the difference value of the two integral data is greater than a threshold value.
