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.
Fig. 1 is a schematic flow chart of a voltage control method of an atomizer according to an embodiment, where the voltage control method includes:
step S110, determining a current temperature value of the nebulizer.
The corresponding materials of each atomizer heating wire are different, the corresponding resistance temperature coefficients are different, and the corresponding current resistance values are also different; when the atomizer in the electronic cigarette is started for the first time, the corresponding current resistance value is smaller due to the fact that the atomizer is within the preset temperature range; after the starting, the temperature rises due to the fact that the resistance corresponding to the heating wire of the atomizer is increased, and therefore the current temperature value of the atomizer is determined to be helpful for judging whether the atomizer is started or in a holding stage after the atomizer is started.
Step S120, determining whether the current temperature value belongs to a preset temperature range, if yes, going to step S130, and if no, going to step S140.
After the current temperature value is obtained through calculation, it may be further determined whether the current temperature value belongs to a preset temperature range, for example, the step S130 is performed when the current temperature value belongs to the preset temperature range, and the step S140 is performed when the current temperature value does not belong to the preset temperature range.
The preset temperature range can be specifically set according to the actual temperature of the place where each area is located, for example, the range of [20 ℃ -30 ℃ ] can be set in southern areas of China.
And step S130, adjusting the voltage of the atomizer to a first preset voltage according to the circuit power supply voltage corresponding to the atomizer and the current temperature value.
Wherein, when confirming that current temperature value belongs to and predetermines the temperature range, can confirm this moment that the atomizer is the initial start, because when the initial start, the atomizer atomizing needs great energy power just can atomize fast, therefore the atomizer voltage that needs this moment is great, further combines the circuit mains voltage that the atomizer corresponds this moment, can adjust atomizer voltage to first preset voltage.
The power supply voltage of the circuit is continuously reduced along with the consumption of the electric quantity of the power supply, so that the process of regulating the voltage of the atomizer is carried out by combining the power supply voltage of the circuit.
In one embodiment, the circuit supply voltage typically takes on the [3, 4.2V ] range.
Step S140, the atomizer voltage is adjusted to a second preset voltage according to the circuit power supply voltage corresponding to the atomizer and the current temperature value, and the second preset voltage is smaller than the first preset voltage.
Wherein, when confirming that current temperature value does not belong to and predetermines the temperature range, can confirm that the atomizer has started, this moment because the current temperature value that the atomizer heater corresponds is higher, relatively speaking, compares with the atomizer first start-up, only needs less atomizer voltage can keep original atomization effect, further combines the circuit mains voltage that the atomizer corresponds this moment, can be with the atomizer voltage regulation to the second voltage of predetermineeing, the second voltage of predetermineeing is less than first voltage of predetermineeing.
In one embodiment, as shown in fig. 2, step S110 includes:
step S112, judging whether the resistance temperature coefficient exceeds a preset resistance temperature coefficient, and entering step S114 when the resistance temperature coefficient exceeds the preset resistance temperature coefficient; when the resistance temperature coefficient does not exceed the preset resistance temperature coefficient, the process proceeds to step S116.
The corresponding resistance temperature coefficients of the different atomizer heating wires are different, the corresponding resistance temperature characteristic curves have different mathematical characteristics, and when the resistance temperature coefficients exceed the preset resistance temperature coefficients, the resistance change characteristics along with the temperature are obvious, and then the process goes to step S116.
And S114, measuring and calculating the current resistance value corresponding to the atomizer heating wire, and determining the current temperature value of the atomizer according to the resistance temperature coefficient corresponding to the atomizer heating wire and the current resistance value.
And the corresponding resistance temperature characteristic curve can be obtained in advance for each atomizer heating wire, and the corresponding current temperature value can be calculated according to the preset temperature, the resistance value corresponding to the preset temperature and the measured current resistance value.
In one embodiment, the resistance-temperature characteristic curve has a linear characteristic, the temperature coefficient of resistance corresponding to the heating wire is TCR1, the preset temperature T0 is 25 degrees, the corresponding preset temperature resistance value is R0, and the current resistance value is R1, and the current temperature value can be calculated according to the linear characteristic:
T1＝T0+(R1-R0)/R1*TCR1
and S116, calculating a corresponding current temperature value according to the corresponding using frequency and the average atomization time length of the atomizer.
When the resistance temperature coefficient corresponding to the atomizer heating wire does not exceed the preset resistance temperature coefficient, the characteristic of the resistance changing along with the temperature is not obvious, the current temperature value corresponding to the atomizer heating wire needs to be determined, measurement and calculation need to be carried out according to the using frequency and the average atomizing duration corresponding to the atomizer, wherein the using frequency of the atomizer refers to the starting times of the atomizer in a unit time range, the average atomizing duration refers to the average time length of the atomizer reaching the preset atomizing effect each time during atomizing, the using frequency and the average atomizing duration of the atomizer can be obtained according to a historical parameter model, obviously, the corresponding using frequency and the average atomizing duration can be obtained by looking up a table according to the historical parameter model, and then the corresponding current temperature value can be calculated.
The voltage control method of the atomizer determines the current temperature value of the atomizer according to the resistance temperature coefficient and the current resistance value corresponding to the heating wire of the atomizer, judges whether the current temperature value belongs to the preset temperature range, if so, adjusts the voltage of the atomizer to the first preset voltage according to the circuit power supply voltage and the current temperature value corresponding to the atomizer, if not, adjusts the voltage of the atomizer to the second preset voltage according to the circuit power supply voltage and the current temperature value corresponding to the atomizer, the second preset voltage is smaller than the first preset voltage, when the atomizer is started in the preset temperature range state and carries out atomization each time, the atomizer can carry out rapid atomization with the larger first preset voltage, and then when the atomizer is in the state exceeding the preset temperature range, the atomization effect of the atomizer can be kept in a stable state with the smaller second preset voltage, and the electric quantity of the power supply unit 320 is saved to a certain extent, the cruising ability of the power supply unit 320 is relatively improved, and meanwhile, the voltage of the atomizer is adjusted and controlled in real time, so that the atomization effect of the atomizer in the electronic cigarette is improved, and the taste and the quality of the electronic cigarette are correspondingly improved.
