Wherein, the driving of the actuating member 260a is preferably provided by an electric driving device such as a motor; the further electric drive device may be controlled by the controller 260 according to the heating position acquired by the information acquisition module 210.

In other embodiments, the optimal heating temperature curves corresponding to different smokeable materials 100 may be stored in the controller 260 in advance; then, the heating curve information stored in the information storage module 110 includes an index or a lookup table corresponding to the heating temperature curve, and then the heating is controlled according to the heating temperature curve by searching the corresponding heating temperature curve according to the index or the lookup table.

In an embodiment, the information acquisition module 210 includes a scanning device (such as a barcode scanning gun) having a scanning function, and when the smokable material 100 is received within the aerosol-generating device 200, the information provided by the barcode, QR code, is collected by scanning the barcode or QR code on the smokable material 100.
In a preferred embodiment, the scanning device is configured to scan by emitting infrared wavelength light or ultraviolet wavelength light.
In another embodiment, the information acquisition module 210 comprises an NFC sensor based on near field communication technology, which is of course an NFC sensor capable of receiving radio frequency signals in a receivable distance range; the NFC receptor may then receive the radio frequency signal transmitted by the NFC tag when the NFC tag alone, or in combination with the smokable material 100, is within the above distance range, and the heating information stored by the NFC tag may be read by the received radio frequency signal, so as to heat the heating location including the smokable material 100.
Further in one embodiment, the information storage unit 110 is disposed on an outer surface of the smokable material 100, while the information acquisition module 210 is configured to be adjacent to the outer surface of the smokable material 100. In a preferred embodiment, the information acquisition module 210 is provided at an opening of a cavity of the aerosol-generating device 200 that receives the smokable material 100, and when the smokable material 100 is gradually inserted into the cavity through the opening, the information acquisition module 210 scans the outer surface of the smokable material 100 during insertion of the smokable material 100, i.e. can accurately collect information provided by the information storage unit 110.
In the embodiment shown in fig. 2-4, the aerosol-generating device 200 further comprises a controller 260, the controller 260 being configured to generate a scheme for controlling the at least one heating region 220 to heat and to control the aerosol-generating device mounting scheme to heat the smokable material 100, in accordance with the information acquired by the information acquisition module 210. The resulting heating protocol includes one or more of the following: heating zones 220 that require heating, heating temperature profiles for the heating zones 220, maximum operating temperatures, maximum heating times, etc., to ensure that the resulting heating profile is favorable for a matched smokable material 100. Of course, a heating profile may be stored within the controller 260 and may be modified by the user to enhance the user experience based on the user's personal preferences or tastes, etc.
In an embodiment, once the heating region 220 in which the aerosol-generating device 200 controls operation does not match the tobacco portion of the smokable material 100, the controller 260 may control the aerosol-generating device 200 to send a signal to alert the user to a notification of a match error.
In an embodiment, the aerosol-generating device 200 is preferably a hand-held aerosol-generating device that is comfortable for a user to hold between the palm or fingers. Preferably, the aerosol-generating device 200 is reusable; each smokable material 100 is disposable.
And may remain in a standby mode without the need to permanently keep heating or other individual features in an active mode, depending on the requirements of use of the aerosol-generating device 200; only when the information acquisition module 210 scans the information storage unit 110, the controller 260 controls the aerosol-generating device 200 to be in the active mode according to the acquisition action, and then the aerosol-generating device can be further switched to the working mode to be heated by detecting the airflow variation information during the user's smoking process. Of course, the standby mode of the aerosol-generating device 200 has lower power consumption than the active mode, based on power saving requirements. On the one hand, may facilitate power saving optimisation and on the other hand safety may be improved, as the aerosol-generating device 200 is only activated when insertion of the smokable material 100 is detected. Thus providing no possibility of energizing the heating element unless the insertion action of the smokable material 100 is acquired by scanning an NFC tag, a barcode or a QR code. In contrast to existing aerosol-generating device 200 products, whether or not smokable material 100 is received, energising the heating element when the control switch is touched may result in dry burn; the gas mist generating device 200 of the present embodiment has higher safety.
It should be noted that the preferred embodiments of the present invention are shown in the specification and the drawings, but the present invention is not limited to the embodiments described in the specification, and further, it will be apparent to those skilled in the art that modifications and changes can be made in the above description, and all such modifications and changes should fall within the protection scope of the appended claims.
