In particular, a current temperature profile value of the aerosol-generating device may be determined from the output power to the heat-generating element of the aerosol-generating device.

It should be noted that, in the whole process of adjusting the temperature curve by the aerosol generating device, the aerosol generating device may perform temperature curve adjustment control at any time according to the characteristics of the generated aerosol, and therefore,step 104 may be performed multiple times, that is, the aerosol generating device receives different temperature curve control commands at different time points, and corresponds to different target temperature curve values.
And 106, if the current temperature curve value is inconsistent with the target temperature curve value, adjusting and controlling the current temperature curve value of the aerosol generating device by adopting a preset control mode so as to adjust the current temperature curve value to the target temperature curve value.
The preset control mode refers to a preset temperature curve adjusting mode, such as a mode of automatically heating to a target temperature curve value or an adjusting mode of adopting constant temperature heating. Specifically, if the current temperature curve value is inconsistent with the target temperature curve value, the controller adjusts and controls the current temperature curve value of the aerosol generating device in a preset control mode, so that the current temperature curve value is adjusted to the target temperature curve value, the accuracy of controlling the temperature curve of the aerosol generating device is guaranteed, and the adjustment and control of the temperature curve of the aerosol generating device are realized.

It can be understood that different users have different requirements on the taste of the aerosol generated by the aerosol generating device, and the requirement on the temperature curve control is not only at a certain time point, but also at multiple use time points, for example, if the whole use time of the aerosol generated by a certain aerosol generating device is 5 minutes, the user may need to control the temperature curve of the aerosol generating device in the first minute, the second minute, the third minute and the fifth minute to make the aerosol generated by the aerosol generating device meet the personal smoking taste, if the temperature curve control is implemented by only adopting a single adjusting mode, it is difficult to ensure the accuracy and speed of the temperature curve control adjustment, and the control efficiency is affected.

The current time point refers to a time point corresponding to the temperature curve control instruction received by the controller in the terminal of the aerosol generating device. It can be understood that, in general, the current temperature curve value of the aerosol generating device in the preheating stage is smaller than the current temperature curve value of the aerosol generating stage, however, the determination of the current stage of the aerosol generating device is determined based on the operating time of the aerosol generating device, and it is worth mentioning that, in the adjustment process of the temperature curve of the aerosol generating device, there is also a situation that the current temperature curve value is adjusted to be larger than the current temperature curve value threshold value of the preheating stage when the last adjustment of the current time point is performed, which affects the determination of the current stage, in order to accurately determine the current stage of the aerosol generating device, in this embodiment, the determination is performed according to the current temperature curve value and the current operating time at the same time, that is, when the current temperature curve value meets the preset preheating temperature curve value threshold value, and the current operating time meets the preset preheating operating time threshold value, the current stage of the aerosol generating device is determined to be a pre-heating stage, otherwise it is a producible aerosol stage. The accuracy of judging the current stage of the aerosol generating device is improved by judging the current temperature curve value and the current working time.

At step 106B2, the current temperature profile value is adjusted based on the generated aerosol level factor.
It can be understood that, in the process of adjusting the temperature curve of the aerosol generating device, the target temperature curve value is obtained according to the control instruction, that is, the temperature curve value set subjectively by the user, because there is a certain deviation in the relationship between the taste of the aerosol generated by the aerosol generating device and the temperature curve change by the user, if the control is performed only according to the target temperature curve value, it is also difficult to ensure the experience of the user in the aerosol suction, therefore, in this embodiment, the current temperature curve value is adjusted and controlled based on the degree coefficient of the generated aerosol, the adjustment range of the temperature curve adjusting process is corrected, the accuracy of the adjustment and control is ensured, and the experience of the user is improved.

Taking a northern winter scenario as an example, a first temperature curve is shown in FIG. 6, where the horizontal axis represents operating time in seconds (S) and the vertical axis represents target temperature curve values in degrees (deg.C). It can be understood that the preheating stage and the aerosol-generating stage have different temperature curve adjustment control modes, so that the curves of the two current stages have a certain difference, and therefore, in the curve fitting process, the target temperature curve values corresponding to different working durations of different stages are respectively subjected to curve fitting, so that the accuracy of the temperature curve of each current stage is ensured.
