The properties of the heat-generating element 13 may be variously set, and for example, they may be: heating plate, heating pin, heating rod, heater wire or silk can also be: a combination of the above two or more different forms of heating elements.
With reference to fig. 2, the control unit 12 is configured to control the battery 11 to supply energy to the heating element 13 and heat the heating element 13 by electromagnetic heating so as to raise the temperature of the heating element 13 from the initial temperature to the first temperature in the first stage; in the second stage, the battery 11 is controlled to provide energy for the heating element 13, and the heating element 13 is heated in an electromagnetic heating mode, so that the temperature of the heating element is increased from the first temperature or maintained at the second temperature; wherein the second temperature is greater than or equal to the first temperature; the duration of the second phase is greater than the duration of the first phase.
In this embodiment, the first phase is a fast ramp phase, and the benefits of the fast ramp are: to rapidly reach a predetermined baking temperature of an aerosol-forming substrate (e.g. a tobacco rod) to enter a smokable state; the second stage is a slow temperature rise stage or a constant temperature state, and the slow temperature rise or constant temperature state has the advantages that: the aerosol-forming substrate is always within the predetermined baking temperature range and the puff mouthfeel is consistent. Thus, the aerosol-generating device of this embodiment can ensure that the aerosol-forming substrate continues to generate aerosol at an optimum temperature by precise control of the temperature, improving the consistency of aerosol aerogel generation.
Compared with the mode of adopting resistance heating, the mode of adopting electromagnetic heating has the following beneficial effects:

2. in the resistance heating mode, the temperature of the heating conductive track is the highest, and then the heating conductive track is conducted to the heating element and then conducted to the cigarette by the heating element, so that the surface temperature of the heating element is uneven; the electromagnetic heating mode is that eddy current is generated by the surface induction of the heating body, so that the surface of the heating body is rapidly heated, the temperature field distribution is very uniform, the path of energy transfer is reduced, and the heating speed of the heating body is higher.

In this embodiment, when the aerosol generating device is in a slow temperature rise state or a constant temperature state, because the heating element 13 is inserted into the aerosol-forming substrate 15, with reference to fig. 4, the temperature of the aerosol-forming substrate 15 (e.g., a cigarette) is gradually reduced along with the direction of the arrow (i.e., from the center to the periphery), the tobacco shred at the center is firstly sucked, and the tobacco shred at the periphery can be gradually kept at a better baking temperature along with the suction time in a slow temperature rise manner, so that the smoke amount is not attenuated.
Further, since the allowable temperature setting is in principle a temperature at which the desired volatile compounds in the cartridge are rapidly volatilized, but below the temperature of the undesired compounds having the higher vaporization temperature, in an alternative embodiment the upper limit of the allowable temperature range for the first and second temperatures is 400 ℃, i.e. the upper limit of the allowable temperature range is 400 ℃ throughout the operation of the aerosol generating device.

Referring to FIG. 6, the comparator U1 in the synchronous detection module 124 compares the drain voltage U of the switch Q1LAnd compared with the reference voltage Vref to generate a synchronization signal having a waveform of high and low levels with a certain width. Meanwhile, the main control module 121 starts outputting the power control signal after detecting the falling edge of the synchronization signal, so as to control the switching tube Q1 to be turned on when receiving the synchronization signal, and turn off the switching tube Q1 for Toff time when the on-time length reaches the preset value Ton 1.

In another alternative embodiment, the first power control signal is used to control the tuning circuit to output the oscillating signal for a duration of (80% to 100%) T.
In one embodiment, the specific process of controlling the temperature by power is: in the first stage, heating is controlled in a constant power mode, wherein the power value can be the maximum output power (namely full power P) of the deviceMaximum of) And may be (80% to 100%) PMaximum of. When the temperature is detected to be greater than or equal to the first temperature (detected by the temperature detection module), the second stage is carried out, heating is controlled in a variable power mode, and the power value can be (20% -40%) P at the non-pumping timeMaximum of(ii) a At the pumping moment, the temperature is greatly reduced, and at the moment, P (80-100%) can be adoptedMaximum ofThe power of the heater heats the cigarettes. In addition, when performing the power control in the second stage, a software algorithm, such as a PID algorithm, may be used to adjust the power so that the temperature coincides with the target temperature (i.e., the second temperature) in the stage, specifically, when the detected temperature is greater than the target temperature, the power is decreased so that the temperature approaches the target temperature, and when the detected temperature is less than the target temperature, the power is increased so that the temperature approaches the target temperature.

Further, since the detection period of the temperature is longer than the period of the oscillation signal, the power is larger the longer the oscillation application time to the coil in one detection period, and therefore, in practical applications, the temperature control can be realized by adjusting the duration of the oscillation signal for each detection period.

In addition, a software algorithm, such as a PID algorithm, may be used to adjust the duration of the oscillation signal so that the temperature is consistent with the second temperature, that is, when the temperature is higher than the second temperature, the oscillation duration is decreased (assuming that the previous detection period is 3 oscillation waveforms, then the current decrease is 2 oscillation waveforms) so that the temperature approaches the target temperature, and when the temperature is lower than the second temperature, the oscillation duration is increased (assuming that the previous detection period is 3 oscillation waveforms, then the current increase is 4 oscillation waveforms) so that the temperature approaches the second temperature.
In one embodiment, a software algorithm, such as a PID algorithm, is used to adjust the oscillation time in both the first stage and the second stage, so as to make the temperature and the target temperature consistent, specifically, the oscillation time duration in the first stage may be (80% to 100%) T; in the second phase, the oscillation duration may be (20% to 60%) T if no pumping action is detected, and (80% to 100%) T if pumping action is detected.
