[0032] The terms used in the embodiments are selected from currently widely used general terms in consideration of the functions of the terms in the present invention. However, different terms may be used according to the intentions of those skilled in the art, precedents, or the emergence of new technologies. In addition, in certain cases, the terms are arbitrarily selected by the applicant of the present disclosure, and the meanings of these terms will be described in detail in the corresponding parts of the specific description. Therefore, the terms used in the present disclosure are not defined based on the term names, but should be defined based on the meanings of the terms and all the contents of the present disclosure.

[0033] Throughout the specification, when a part "includes" a certain constituent element, unless the context clearly stipulates otherwise, the part does not exclude another constituent element, but may also include another constituent element. In addition, terms such as "~ part", "~ module" and the like used in the specification may refer to a unit for processing at least one function or action, and may be implemented as hardware, software, or a combination of hardware and software.

[0034] As used herein, expressions such as "at least one of..." do not modify each of the listed constituent elements, but modify all constituent elements. For example, the expression "at least one of a, b, and c" should be interpreted as including a, b, c, a and b, a and c, b and c, or a, b and c.

[0035] In the following embodiments, "aerosol generating article" as an article containing a medium refers to an article that transfers the medium as the aerosol passes through the corresponding article. A representative example of an aerosol generating article is a cigarette, but the scope of the present disclosure is not limited thereto.

[0036] In the following embodiments, "upstream" or "upstream direction" refers to the direction away from the user's (smoker's) mouth; "downstream" or "downstream direction" refers to the direction close to the user's mouth. Upstream and downstream are used to describe the relative positions of the components of the aerosol-generating article.

[0037] In the following embodiments, "puff" refers to inhalation by a user, and inhalation refers to a situation where a user inhales into the user's oral cavity, nasal cavity, or lungs through the mouth or nose.

[0038] In one embodiment, the aerosol generating device may be a device that electrically heats an aerosol generating article contained in an inner space thereof to generate aerosol.

[0039] The aerosol generating device may include a heater. In one embodiment, the heater may be a resistive heater. For example, the heater may include a conductive track, and the heater is heated as current flows through the conductive track.

[0040] The heater may comprise a tubular heating element, a plate-shaped heating element, a needle-shaped heating element or a rod-shaped heating element, and the inside or the outside of the aerosol-generating article may be heated depending on the shape of the heating element.

[0041] The aerosol generating product may include a tobacco rod and a filter rod. The tobacco rod may be made of a sheet, a strand, or shredded tobacco cut from a tobacco sheet.

The cartridge may be detachably coupled to the main body, but is not limited thereto. The cartridge and the main body may be integrally formed or assembled, and the cartridge may be fixed to prevent separation due to user operation. The cartridge may be mounted to the main body with the aerosol generating substance contained therein. However, the aerosol generating substance may also be injected into the cartridge while the cartridge is coupled to the main body.

For example, the liquid composition may be a liquid containing a tobacco substance containing a volatile tobacco aroma component, or may be a liquid containing a non-tobacco substance.

[0046] The cartridge can be operated based on an electrical signal or wireless signal transmitted by the main body, so as to perform the function of converting the phase of the aerosol-generating substance inside the cartridge into a gas phase to generate an aerosol. The aerosol can be a mixed gas of vaporized particles generated by the aerosol-generating substance and air.

[0047] In another embodiment, the aerosol generating device can generate an aerosol by heating a liquid composition, and deliver the generated aerosol to a user through a cigarette. That is, the aerosol generated by the liquid composition can move along the airflow channel of the aerosol generating device, and the airflow channel enables the aerosol to be delivered to the user via the cigarette.

[0051] When a voltage (e.g., an alternating voltage) is applied to the vibrator, the vibrator may generate heat and / or ultrasonic vibrations, and the heat and / or ultrasonic vibrations generated by the vibrator may be transmitted to the aerosol-generating substance absorbed by the core material. The aerosol-generating substance absorbed by the core material may be converted into a gas phase by the heat and / or ultrasonic vibrations transmitted by the vibrator, and finally generate an aerosol.

[0052] For example, the viscosity of the aerosol generating substance absorbed by the core material is reduced by heat generated by the vibrator, and the aerosol generating substance with reduced viscosity is transformed into fine particles by ultrasonic vibration generated by the vibrator, thereby generating aerosol, but the invention is not limited thereto.

[0053] In yet another embodiment, the aerosol generating device may heat the aerosol generating article contained in the aerosol generating device by induction heating to generate the aerosol.

[0054] The aerosol generating device may include a susceptor and a coil. In one embodiment, the coil may apply a magnetic field to the susceptor. When the aerosol generating device supplies power to the coil, a magnetic field may be formed inside the coil. In one embodiment, the susceptor may be a magnetic element that generates heat through an external magnetic field.

In another example, the power supply from the heating integrated circuit to the heater 150 may be controlled according to a control command of the control unit 110.

[0084] The control unit 110 may analyze the sensing result of the sensing unit 120 and control subsequent processing. For example, the control unit 110 may control the power supplied to the heater 150 according to the sensing result of the sensing unit 120, thereby starting and shutting down the heater 150. For another example, the control unit 110 may control the amount of power supplied to the heater 150 and the power supply time according to the sensing result of the sensing unit 120, so that the heater 150 is heated to a predetermined temperature or maintained at a suitable temperature.

[0085] The control unit 110 may control the output unit 130 according to the result sensed by the sensing unit 120. For example, when the number of puffs counted by the puff sensor 126 reaches a preset number, the control unit 110 may inform the user through at least one of the display unit 132, the tactile unit 134, and the sound output unit 136 that the aerosol generating device 100 is about to stop.

[0086] In one embodiment, the control unit 110 may control the power supply time and / or power supply amount to the heater 150 according to the state of the aerosol generating product sensed by the sensing unit 120. For example, when the aerosol generating product is in an over-humidified state, the control unit 110 may control the power supply time to the induction coil, thereby extending the preheating time of the aerosol generating product compared to the normal state.
