Background
The existing electronic cigarette output voltage modes comprise the following three different modes: constant voltage output, constant power output, and constant effective value output.
The constant voltage output is to drive the load resistor with a constant voltage value, and the mode has the disadvantages that when the voltage of the battery is lower, the output voltage is reduced along with the voltage of the battery, and meanwhile, the resistance value of the heating wire is changed in the temperature change process, so that the output power is changed in a larger range, and the taste of the generated smoke is further influenced;
the constant power output is to detect the current I flowing through the output resistor and the voltage value U loaded on the load resistance value at the same time, and calculate the output power through the following power calculation formula:
P＝D×U×I；
the constant power output means that under the regulation of the control unit, the PWM (Pulse Width Modulation) voltage value of the heating resistor is synchronously changed along with the resistance value of the heating resistor so as to keep the same power, so that the atomization amount generated by heating the smoke liquid by the heating resistor is the same;

in the above equation, D represents the duty ratio of the PWM wave.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
Referring to fig. 1, fig. 1 is a block flow diagram of a method for adjusting an output voltage of an electronic cigarette according to an embodiment of the present invention, where the method includes the following steps:
s1, zeroizing the time for heating the smoke unit by the heating unit, and taking the current residual quantity of the tobacco tar in the smoke unit as an initial residual quantity.
Specifically, the method provided by the embodiment of the present invention is applied to an electronic cigarette including a smoke unit and a heating unit for heating the smoke unit, and step S1 is an initialization method of the electronic cigarette, where the initialization of the electronic cigarette is to unify parameters required to be used next by the embodiment of the present invention, and the existing electronic cigarette is divided into a disposable electronic cigarette and an electronic cigarette with a replaceable cartridge, where the disposable electronic cigarette is equivalent to the smoke unit in the embodiment of the present invention and the cartridge stores therein a tar capable of generating smoke after being heated.
For example, in the assembly process of a disposable electronic cigarette, the phenomenon that the disposable electronic cigarette is easily triggered by mistake can be caused, so that the smoke unit is heated and burnt, and the problem cannot be avoided by an algorithm or load resistance detection, because the triggering mechanism needs to perform internal feedback detection in a normal working mode of a chip or start the heating unit to perform dry burning; the method for initializing the disposable electronic cigarette product can be characterized in that after all components are detected and assembled, the battery is disconnected from an electronic circuit through a switch or a plastic insert, so that the phenomenon of dry burning caused by the fact that the heating unit is triggered by mistake under the condition that no tobacco tar is injected is avoided;
for the electronic cigarette product with the replaceable cigarette cartridge, the initialization can be carried out through the following three schemes: 1. resetting in a key mode, namely manually pressing a reset switch after replacing a new smoke cartridge each time, and zeroing the heating time of the smoke unit; 2. the method comprises the following steps of quickly plugging and unplugging a cigarette cartridge for multiple times within a certain time to perform reset operation, so that the whole system of the electronic cigarette is initialized; 3. and (3) electronic tag identification, wherein the method mainly comprises the steps of reading the electronic tag code in the cigarette cartridge, comparing the electronic tag code with the last cigarette cartridge code, initializing the system if the electronic tag code is not consistent with the last cigarette cartridge code, and keeping the previous heating and margin data if the electronic tag code is consistent with the last cigarette cartridge code.
S2, outputting heating voltage through the heating unit to enable the heating unit to heat the smoke unit.
Further, step S2 is preceded by the steps of:
judging whether the electronic cigarette is in a smoking state, wherein:
if so, enabling the heating unit to output the heating voltage;
if not, the heating unit stops working.
In an embodiment of the present invention, as an example, the method for determining whether the electronic cigarette is in a smoking state may be that an airflow sensor detects a value of airflow variation, and whether the electronic cigarette is in the smoking state is determined according to whether the airflow sensor senses airflow variation similar to smoking.
And S3, calculating heating power according to the heating voltage, comparing the heating power with preset power, and carrying out feedback regulation on the heating voltage according to a comparison result and a preset rule.
Further, in step S3:
the preset power at least comprises a first preset power, a second preset power and a third preset power which are sequentially increased in an increasing mode, and the first preset power, the second preset power and the third preset power respectively correspond to a first preset voltage, a second preset voltage and a third preset voltage;
the preset rule is as follows:
if the heating power is smaller than the first preset power, keeping the heating voltage unchanged;
if the heating power is equal to or greater than the first preset power and less than the second preset power, setting the heating voltage to be equal to the first preset voltage;
if the heating power is equal to or greater than the second preset power and less than the third preset power, setting the heating voltage to be equal to the second preset voltage;
and if the heating power is equal to the third preset power, setting the heating voltage to be equal to the third preset voltage.
It should be noted that, in the embodiment of the present invention, an increasing three-level preset power is designed, and in practical application, more levels of the preset power can be designed according to needs, so as to satisfy the effects that the output power of the electronic cigarette gradually increases, and the taste smoothly transitions at any time.
And S4, acquiring the total working time of the electronic cigarette, and linearly adjusting the heating voltage according to the total working time.
Further, step S4 includes the following sub-steps:
s41, defining the working time of the electronic cigarette every time as Ti, and defining the total working time as T, wherein the total working time T meets the following relational expression (1):
and S42, increasing the heating voltage by a preset voltage increment every time when the total working time T is cumulatively increased by a preset working time.
The preset working time can be set according to actual conditions, and illustratively, the heating voltage and the total working time T are in a linear relation, namely, the heating voltage is slowly increased along with the increase of the total working time T under the condition of continuous working of the electronic cigarette.
Generally, when the heating voltage is increased, the actual working power of the smoke unit is also increased, so as to improve the release amount of smoke, and thus, the dynamic improvement of the output power has the following two advantages: firstly, after a general electronic cigarette is smoked to a certain degree, as the amount of the tobacco tar stored in the smoke unit is reduced, the amount of the tobacco tar atomized in unit time is correspondingly reduced, and in order to achieve the same user experience, the output power is increased so as to keep the smoke output in unit time; secondly, no matter in the electronic cigarette with the cotton core or the ceramic core as the smoke unit, with the increase of the service time, the surfaces of the heating unit and the smoke unit can generate some oxides due to chemical reaction and are attached to the place where the heating wire of the electronic cigarette is contacted with the tobacco tar, so that the tobacco tar atomization amount is reduced under the same power, the output power is increased, and the user experience can be more consistent.
Further, after step S42, the method further includes the steps of:
s43, defining the allowance of the smoke unit as L, wherein the allowance L meets the following relational expression (2):
L＝L 0 -α×T (2)；
in the relation (2), L 0 For the value after the smoke unit is initialized, alpha is a preset total working time length coefficient, and alpha is in positive correlation with the average power of the electronic cigarette;
if the margin L is less than the preset minimum margin threshold value L MIN And stopping the heating unit.
The main influence factor of alpha is the average power of the equivalent output, i.e. the larger the power, the larger the consumption of the tobacco tar in the smoke unit, the smaller the power, the smaller the amount of the tobacco tar consumed, due to the protection mechanism and the system error, a certain margin is reserved for the calculation of the amount of the tobacco tar, i.e. the minimum margin threshold, when L is reduced to be lower than L MIN And then, stopping the heating unit and closing all functions of normal smoking, thereby preventing the smoke unit from being burned dry and generating potential safety hazards.
Further, after step S43, the method further includes the steps of:
s44, defining the heating temperature output by the heating unit as T emp Said heating temperature T emp Satisfies the following relation (3):
T emp ＝A×t 0 +K×(T-t 0 ) (3)
in the relation (3), t 0 Setting the initial working time of the heating unit, wherein A is a preset temperature change coefficient, and K is the heating coefficient of the heating unit;
if the heating temperature T is emp And when a preset temperature increment is added in an accumulated manner, increasing the heating voltage by the preset voltage increment.
In particular, K is determined by the material of the heating unit and its resistivity.
The present invention further provides another embodiment, and for step S44, the following steps may also be performed:
defining the heating temperature output by the heating unit as T emp Said heating temperature T emp Satisfies the following relation (3):
T emp ＝A×t 0 +K×(T-t 0 ) (3)
in the relation (3), t 0 Setting the initial working time of the heating unit, wherein A is a preset temperature change coefficient, and K is a heating coefficient of the heating unit;
if the heating temperature T is emp And when a preset temperature increment is added in an accumulated manner, reducing the heating voltage by the preset voltage increment.
In this embodiment, the heating voltage is gradually decreased with the gradual increase of the heating temperature, which is set in consideration of the fact that the materials constituting the heating units may have different temperature heating coefficients, compared to another embodiment, if the heating voltage is increased when the temperature is increased, the material of the corresponding heating unit has the characteristic of positive temperature coefficient; and if the heating voltage is reduced when the temperature is increased, the material of the corresponding heating unit has the characteristic of negative temperature coefficient.
The invention has the advantages that the voltage output and the heating element which are certainly existed in the electronic cigarette are adopted as data sources, the temperature of the heating unit and the residual tobacco tar amount of the smoke unit can be calculated through an algorithm, the technical effects of preventing dry burning and automatically adjusting the output voltage to achieve gradual power change are further realized, and the manufacturing cost is saved on the premise of realizing the functions.
