[001] The present invention relates to an aerosol generating device, an aerosol generating system and a method for operating and controlling an aerosol generating article.

[002] The state of the art comprises aerosol generating devices for generating an inhalable vapor. Such devices can heat the aerosol-forming substrate to a temperature at which one or more components of the aerosol-forming substrate are volatilized without burning the aerosol-forming substrate. The aerosol-forming substrate may be provided as part of an aerosol generating article. The aerosol generating article may have a column shape for insertion of the aerosol generating article into a cavity, such as a heating chamber, of the aerosol generating device. A heating element may be disposed in or around the heating chamber to heat the aerosol-forming substrate once the aerosol generating article is inserted into the heating chamber of the aerosol generating device.Aerosol generating devices are typically designed to operate best when used with a unique and specifically designed aerosol generating article. Furthermore, manufacturers of aerosol generating articles may offer a product line of aerosol generating articles in a variety of types with different characteristics, such as aroma, nicotine content, amount of aerosol generating substrate, quality of the aerosol forming substrate, and / or material(s) comprised in the aerosol forming substrate.

[003] It would be desirable to provide an aerosol generating device capable of identifying an aerosol generating article. It would be desirable to provide an aerosol generating device capable of detecting an authorized aerosol generating article. It would be desirable to provide a device Petition 870250093338, dated 10 / 13 / 2025, page 8 / 59 2 / 40 A reliable aerosol-generating device capable of detecting an aerosol-generating article with enhanced reliability. It would be desirable to provide an aerosol-generating device with improved detection capabilities. It would be desirable to have an aerosol-generating device providing an optimized user experience. It would be desirable to have an aerosol-generating article that allows for improved identification by an aerosol-generating device.

[004] According to one embodiment of the invention, an aerosol generating device can be provided for use with an aerosol generating article of a first type and for use with an aerosol generating article of a different second type. The aerosol generating device may comprise an article detector that can be configured to detect whether an aerosol generating article for use with the device can be of the first type or the second type. The aerosol generating device may further comprise a controller. The controller can be configured to control the operation of the aerosol generating device in a first operating mode when an aerosol generating article of the first type can be detected by the article detector. The controller can be configured to control the operation of the aerosol generating device in a second operating mode when an aerosol generating article of the second type can be detected by the article detector.The first operating mode may differ from the second operating mode by one or more of the following: a predetermined maximum number of puffs before each respective operating mode can be terminated; a predetermined maximum duration before each respective operating mode can be terminated; a predetermined maximum volume of aerosol generated before each respective operating mode can be terminated.

[005] According to one embodiment of the invention, it is provided Petition 870250093338, dated 10 / 13 / 2025, page 9 / 59 3 / 40 An aerosol generating device for use with an aerosol generating article of a first type and for use with an aerosol generating article of a different second type. The aerosol generating device comprises an article detector configured to detect whether an aerosol generating article for use with the device is of the first type or of the second type. The aerosol generating device further comprises a controller. The controller is configured to control the operation of the aerosol generating device in a first operating mode when an aerosol generating article of the first type is detected by the article detector. The controller is configured to control the operation of the aerosol generating device in a second operating mode when an aerosol generating article of the second type is detected by the article detector. The first operating mode differs from the second operating mode by one or more of the following: a predetermined maximum number of puffs before each respective operating mode is terminated; a predetermined maximum duration before each respective operating mode is terminated; a predetermined maximum volume of aerosol generated before each respective operating mode is terminated.

[006] The aerosol generating device according to the invention may be able to identify an aerosol generating article, particularly an authorized aerosol generating article. The aerosol generating device according to the invention may be able to operate differently depending on an identified type of aerosol generating article. This may be beneficial if aerosol generating articles of different types are used with a single aerosol generating device. By way of example, an aerosol generating article of a first type may allow a different user experience compared to an aerosol generating article of a second type.

Having a single aerosol generating device capable of operating in different modes for both different aerosol generating articles can be convenient for the user. For example, this avoids the need for the user to own a variety of different devices, each for use with a specific type of aerosol generating article.

[007] The first operating mode may also differ from the second operating mode by a heating profile of a heating element of the aerosol generating device.

[008] A heating element heating profile may comprise one or more of the following: a heating element operating duration, a maximum heating element temperature, a minimum heating element temperature, an average heating element temperature, and a heating element temperature profile. A temperature profile may comprise one or more temperature setpoints to which the aerosol-forming substrate and / or the heating element are heated. For example, a larger aerosol volume per puff may be desired in the first operating mode. This can be achieved by, for example, one or both of a higher maximum temperature and a higher average heating element temperature. In the second operating mode, a lower aerosol volume per puff may be desired.This can be achieved by, for example, one or both of a lower maximum temperature and a lower average temperature of the heating element. In another example, a faster aerosol distribution may be desired in the first operating mode. This can be achieved by, for example, a faster temperature rise in the temperature profile of the heating element. A slower aerosol distribution may be desired in the second operating mode. This can be achieved by...

Petition 870250093338, dated 10 / 13 / 2025, page 28 / 59 22 / 40 Heaters formed in this way can be used both to heat and to monitor the temperature of the heating elements during operation.

[0083] An external heating element may take any suitable form. For example, an external heating element may take the form of one or more flexible heating sheets on a dielectric substrate, such as polyimide. The flexible heating sheets may be shaped to fit the perimeter of the receiving substrate cavity. Alternatively, an external heating element may take the form of a metal grid or grids, a flexible printed circuit board, a molded interconnect device (MID), a ceramic heater, a flexible carbon fiber heater, or it may be formed by using a coating technique, such as plasma vapor deposition, onto a suitably shaped substrate. An external heating element may also be formed using a metal that has a defined temperature-resistivity relationship.In such an exemplary device, the metal can be formed as a strip between two layers of suitable insulating materials. An external heating element formed in this way can be used both for heating and for monitoring the temperature of the external heating element during operation.

[0084] As an alternative to an electrically resistive heating element, the heating element can be configured as an induction heating element. The induction heating element may comprise a heating induction coil and a susceptor. In general, a susceptor is a material that will be able to generate heat when penetrated by an alternating magnetic field. When located in an alternating magnetic field. If the susceptor is conductive, then eddy currents nor Petition 870250093338, dated 10 / 13 / 2025, page 29 / 59 23 / 40 will rarely be induced by the alternating magnetic field. If the susceptor is magnetic, then another effect that contributes to heating is commonly referred to as hysteresis losses. Hysteresis losses occur mainly due to the movement of magnetic domain blocks within the susceptor particles, because their magnetic orientation will align with the alternating magnetic induction field. Another effect that contributes to hysteresis loss is when magnetic domains grow or shrink within the susceptor. Commonly, all these changes in the susceptor that occur at a nanoscale or below are referred to as hysteresis losses because they produce heat in the susceptor. Therefore, if the susceptor is both magnetically and electrically conductive, both hysteresis losses and the generation of eddy currents will contribute to the heating of the susceptor.If the susceptor is magnetic but not conductive, then hysteresis losses will be the only means by which the susceptor will heat up when penetrated by an alternating magnetic field. The susceptor may be electrically conductive or magnetic, or both electrically conductive and magnetic. An alternating magnetic field generated by one or more induction coils heats the susceptor, which then transfers the heat to the aerosol-forming substrate, so that an aerosol is formed. Heat transfer can be primarily by heat conduction. Such heat transfer is the best option if the susceptor is in close thermal contact with the aerosol-forming substrate.

[0085] The aerosol generating device may comprise a power source, typically a battery, within a main body of the aerosol generating device. In one embodiment, the power source is a lithium-ion battery.

Alternatively, the power source may be another form of charge storage device, such as a capacitor. The power source may require recharging and may have a capacity that allows for the storage of sufficient energy for one or more usage experiments; for example, the power source may have sufficient capacity to generate aerosol continuously for a period of about six minutes or for a period that is a multiple of six minutes. In another example, the power source may have sufficient capacity to provide a predetermined number of distinct puffs or activations of the heating element.

[0086] The invention also relates to an aerosol generating device for use with a plurality of different aerosol generating articles.
