Description
Technical Field
The application relates to the field of smoking articles, in particular to a power adjusting method and device of electronic cigarettes, a storage medium and the electronic cigarettes.
Background
The electronic cigarette products in the current market are prepared by heating liquid electronic cigarette liquid through heating elements such as heating wires or atomizing cores, so that the electronic cigarette liquid is atomized to generate smog which can be sucked. Thus, the amount of smoke generated is directly related to the power of the e-cigarette.
In the existing electronic cigarette, there is no clear correlation between the amount of smoke generated and the airflow rate when the user sucks the electronic cigarette, and only one starting threshold is simply set, and when the airflow rate when the user sucks the electronic cigarette exceeds the starting threshold, the atomizer is started to heat the tobacco tar. Otherwise, the atomizer is controlled to stop working. Thus, such an e-cigarette only includes 2 states of generating smoke and not generating smoke, and the amount of smoke is determined by its preset power. In this case, when the user is used to smoking the electronic cigarette with a larger smoking force (that is, means that the airflow velocity is larger when smoking the electronic cigarette), the electronic cigarette cannot generate smoke amount corresponding to more than the preset power, and the difference between the smoke amount and the effect of the cigarette is larger, so that the user experience is worse. When a user is used to sucking the electronic cigarette with smaller sucking force (namely, the airflow velocity is smaller when sucking the electronic cigarette), a large amount of smoke generated by the electronic cigarette is not sucked in time, so that the user is easy to stay in the electronic cigarette for too long to generate burnt smell, and meanwhile, the power and the smoke liquid are wasted. In summary, the existing electronic cigarette cannot automatically adjust the power of the electronic cigarette according to the habit of the user, and the user experience is poor.

The existing electronic cigarette lacks a mechanism for automatically adjusting the power of the electronic cigarette according to the habit of a user, and the application improves the mechanism.
Fig. 1 is a schematic flow chart of a power adjustment method of an electronic cigarette according to an embodiment of the present application, which includes the following steps.
S1: acquiring preset parameters; the preset parameters comprise preset power P of the electronic cigarette s First weight W 1 Second weight W 2 ；
S2: obtaining a first average airflow velocity of the last n times of sucking the electronic cigaretteWherein n is a positive integer;
s3: obtaining a second average airflow velocity of the last m times of sucking the electronic cigaretteWherein m is a positive integer, and m>n；
S4: according to the formulaCalculating a theoretical airflow velocity V;
s5: according to the formulaCalculating theoretical power P;
s6: and adjusting the power of the electronic cigarette according to the theoretical power P.
Specifically, the preset power of the electronic cigarette refers to the power at the time of the next suction. If the user cannot automatically adjust the power of the electronic cigarette, the preset power is the fixed power of the electronic cigarette in design; if the user can manually adjust the power of the electronic cigarette, the preset power is the power set by the user when the next suction is performed.
First weight W 1 Second weight W 2 Is a real number. In a preferred embodiment of the application, the first weight W 1 Second weight W 2 The values of the (C) are all larger than 0. In a preferred embodiment of the application, the first weight W 1 And a second weight W 2 The sum is 1. For example, a first weight W 1 Equal to 0.2, a second weight W 2 Equal to 0.8.
When the user uses the electronic cigarette, the heating components such as the heating wire or the atomizing core of the electronic cigarette start to work by sucking the electronic cigarette, and when the sucking is finished, the heating components such as the heating wire or the atomizing core stop to work. Therefore, unless specifically described, the suction of the electronic cigarette 1 time referred to in the present application refers to a process from the start to the stop of the operation of the heating means.
The last n puffs of the e-cigarette means that the e-cigarette is smoked n times closest to the time interval between the next puffs of the e-cigarette. Similarly, the last m puffs of the e-cigarette means that the e-cigarette is smoked m times closest to the time interval in which the e-cigarette is smoked next. For example, the electronic cigarette is smoked 5 times in total, and is respectively marked as a first time of smoking, a second time of smoking, a third time of smoking, a fourth time of smoking and a fifth time of smoking according to time sequence, then the last 2 times of smoking refers to the fourth time of smoking and the fifth time of smoking, and the last 4 times of smoking refers to the second time of smoking, the third time of smoking, the fourth time of smoking and the fifth time of smoking. The last 1 puff of the e-cigarette is referred to as the fifth puff.
When a user sucks the electronic cigarette, the user sucks smoke through the flow of gas in the airflow channel of the electronic cigarette. Thus, the gas flow rate referred to herein refers to the flow rate of the gas in the flow path of the e-cigarette. The gas flow rate may be detected by a gas sensor, such as a gas flow rate sensor, or a gas flow meter in combination with a timer may be used to obtain the gas flow rate. Of course, it will be understood by those skilled in the art that the average airflow rate referred to herein may be an arithmetic average, i.e., the sum of the airflow rates from each puff divided by the number of puffs. The average airflow rate may also be a weighted average, i.e., the airflow rates for each puff may be weighted differently.
First average airflow rate for last n puffs of the e-cigaretteFor characterizing short-term habits of the user. n is a positive integer, and in a preferred embodiment of the application n is 15. Of course, the specific value of n is not particularly limited in the present application.
Second average airflow velocity for last m puffs of the e-cigaretteFor characterizing the long-term habits of the user. m is a positive integer, and the value needs to be greater than n, in a preferred embodiment of the present application, m is the total number of times of smoking of the electronic cigarette.
Thus, when the first average airflow velocityAnd a second average airflow rate->When they are not equal, it is indicated that the short-term habit and the long-term habit of the user are different, and thus it is determined that the user wants to change the sucking force (i.eAirflow rate) to vary the amount of smoke ingested.
At this time, the formula is passedAnd estimating the airflow velocity of the electronic cigarette sucked by the user next time to obtain a theoretical airflow velocity V. Obviously, when the first average airflow velocity +.>Greater than the second average airflow rate->(meaning that the user increases the suction force), the theoretical airflow rate V will be greater than the second average airflow rate +.>Thus according to the formula->The calculated theoretical power P is larger than the preset power, so that the power of the electronic cigarette is improved, and the electronic cigarette is ensured to generate more smoke for a user to inhale. When the first average airflow velocity +>Less than the second average airflow rate->(meaning that the user reduces the suction force) the theoretical airflow rate V will be smaller than the second average airflow rate +.>Thus according to the formula->The calculated theoretical power P is smaller than the preset power, so that the power of the electronic cigarette is reduced, and the situation that a user cannot timely suck a large amount of cigarettes due to smaller suction force is avoidedThe smoke causes a burnt smell and also reduces the consumption of tobacco tar and power. In summary, the embodiment of the application realizes automatic adjustment of the power of the electronic cigarette according to the suction habit of the user, and greatly improves the user experience.
Referring to FIG. 2, a first average airflow velocity is determined according to an embodiment of the present applicationThe method flow diagram of (1) comprises the following steps.
S21: acquiring a first airflow velocity V of the electronic cigarette sucked for 1 last time 1 ；
S22: obtaining a third average airflow velocity of the electronic cigarette sucked for n-1 times except the electronic cigarette sucked for 1 time recently in the electronic cigarette sucked for n times recently
S23: according to the formulaCalculating said first average airflow rate +.>
Wherein the preset parameters further comprise a third weight W 3 And a fourth weight W 4 . Third weight W 3 And a fourth weight W 4 Are real numbers. In a preferred embodiment of the application, the third weight W 3 And a fourth weight W 4 The values of the (C) are all larger than 0. In a preferred embodiment of the application, the third weight W 3 And a fourth weight W 4 The sum is 1. For example, a third weight W 3 Equal to 0.1, fourth weight W 4 Equal to 0.9.
As described above, if the electronic cigarette is smoked 5 times, the first, second, third, fourth and fifth puffs are respectively marked according to the time sequence. When the value of n is 4, the electronic cigarettes sucked for n-1 times except the electronic cigarette sucked for 1 time recently in the electronic cigarette are referred to as second suction, third suction and fourth suction.
