DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] The terms used in the examples are currently used as widely as possible while taking into consideration the functions of the present invention, but this may change depending on the intentions or precedents of the engineers in the field, the emergence of new technologies, etc. In addition, in certain cases, the applicant may arbitrarily select terms, and in this case, the meanings of the terms are described in detail in the description of the invention. Therefore, the terms used in the present invention should be defined based on the meanings of the terms and the overall content of the present invention, rather than simply the names of the terms.

[0023] Throughout the specification, when a part "includes" a certain component, this does not mean excluding other components, but may further include other components, unless otherwise specified. Furthermore, terms such as "... unit" and "... module" described in the specification mean a unit that processes at least one function or operation, which is embodied in hardware or software, or a combination of hardware and software.

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG. 1 is a block diagram of a semiconductor memory device according to an embodiment of the present invention;

[0025] In the following, an embodiment of the present invention will be described in detail with reference to the drawings.

[0026] 1 to 3 are diagrams showing an example in which a cigarette is inserted into an aerosol generating device.

[0027] 1, the aerosol generating device 1 includes a battery 11, a control unit 12, and a heater 13. 2 and 3, the aerosol generating device 1 further includes a vaporizer 14. Furthermore, a cigarette 2 can be inserted into the internal space of the aerosol generating device 1.

[0028] Components according to this embodiment are shown in the aerosol generating device 1 shown in Figures 1 to 3. Therefore, it will be understood by a person having ordinary skill in the technical field according to this embodiment that the aerosol generating device 1 may further include other general-purpose components in addition to the components shown in Figures 1 to 3.

[0029] Also, although the aerosol generating device 1 is shown in FIGS. 2 and 3 as including the heater 13, the heater 13 may be omitted if desired.

[0030] In Fig. 1, the battery 11, the control unit 12, and the heater 13 are shown arranged in a line. In Fig. 2, the battery 11, the control unit 12, the vaporizer 14, and the heater 13 are shown arranged in a line. In Fig. 3, the vaporizer 14 and the heater 13 are shown arranged in parallel. However, the internal structure of the aerosol generating device 1 is not limited to that shown in Figs. 1 to 3. In other words, the arrangement of the battery 11, the control unit 12, the heater 13, and the vaporizer 14 may be changed depending on the design of the aerosol generating device 1.

[0031] When the cigarette 2 is inserted into the aerosol generating device 1, the aerosol generating device 1 activates the heater 13 and / or the vaporizer 14 to generate an aerosol. The aerosol generated by the heater 13 and / or the vaporizer 14 passes through the cigarette 2 and is delivered to the user.

[0032] If necessary, the aerosol generation device 1 can heat the heater 13 even when a cigarette 2 is not inserted in the aerosol generation device 1 .

[0033] The battery 11 supplies power used for the operation of the aerosol generation device 1. For example, the battery 11 supplies power to heat the heater 13 or the vaporizer 14, and supplies power necessary for the operation of the control unit 12. The battery 11 also supplies power necessary for the operation of a display, a sensor, a motor, and the like provided in the aerosol generation device 1.

[0034] The control unit 12 generally controls the operation of the aerosol generating device 1. Specifically, the control unit 12 controls the operation of not only the battery 11, the heater 13, and the vaporizer 14, but also other components included in the aerosol generating device 1. The control unit 12 may also check the state of each component of the aerosol generating device 1 to determine whether the aerosol generating device 1 is in an operable state.

[0035] The control unit 12 includes at least one processor. The processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. It will be understood by those skilled in the art that the present embodiment may also be implemented as other types of hardware.

[0036] The heater 13 is heated by power supplied from the battery 11. For example, when a cigarette is inserted into the aerosol generating device 1, the heater 13 is located outside the cigarette. Thus, the heated heater 13 can increase the temperature of the aerosol-generating material inside the cigarette.

[0037] The heater 13 may be an electrically resistive heater. For example, the heater 13 includes an electrically conductive track, and the heater 13 is heated by passing an electric current through the electrically conductive track. However, the heater 13 is not limited to the above example, and is not limited as long as it can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating device 1, or may be set to a desired temperature by a user.

[0038] Meanwhile, as another example, the heater 13 may be an induction heater. Specifically, the heater 13 may include an electrically conductive coil for inductively heating the cigarette, and the cigarette may include a susceptor that can be heated by the induction heater.

[0039] For example, the heater 13 may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and heats the inside or outside of the cigarette 2 depending on the shape of the heating element.

[0040] Furthermore, a plurality of heaters 13 may be disposed in the aerosol generating device 1. In this case, the plurality of heaters 13 may be disposed so as to be inserted inside the cigarette 2, or may be disposed outside the cigarette 2. Furthermore, some of the plurality of heaters 13 may be disposed so as to be inserted inside the cigarette 2, and the rest may be disposed outside the cigarette 2. Furthermore, the shape of the heater 13 is not limited to the shapes shown in Figs. 1 to 3, and may be manufactured into various shapes.

[0041] The vaporizer 14 heats the liquid composition to generate an aerosol, which is then transmitted to the user through the cigarette 2. In other words, the aerosol generated by the vaporizer 14 can travel along an airflow passage of the aerosol generating device 1, which is configured to allow the aerosol generated by the vaporizer 14 to be transmitted to the user through the cigarette 2.

[0042] For example, the vaporizer 14 includes, but is not limited to, a liquid reservoir, a liquid delivery means, and a heating element. For example, the liquid reservoir, the liquid delivery means, and the heating element may be included in the aerosol generation device 1 as independent modules.

[0043] The liquid storage unit can store a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, or a liquid containing a non-tobacco substance. The liquid storage unit may be manufactured so as to be detachable from the vaporizer 14, or may be manufactured integrally with the vaporizer 14.

[0044] For example, the liquid composition may include water, solvent, ethanol, plant extracts, flavors, flavorings, or vitamin mixtures. The flavors may include, but are not limited to, menthol, peppermint, spearmint oil, various fruit scent ingredients, and the like. The flavorings may include ingredients that provide a variety of flavors or tastes to the user. The vitamin mixture may include, but is not limited to, at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also include an aerosol forming agent, such as glycerin and propylene glycol.

[0045] The liquid transfer means can transfer the liquid composition in the liquid reservoir to the heating element. For example, the liquid transfer means can be a wick such as, but not limited to, cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0046] The heating element is an element for heating the liquid composition transferred by the liquid transfer means. For example, the heating element may be, but is not limited to, a metal hot wire, a metal hot plate, a ceramic heater, etc. The heating element may be made of a conductive filament such as a nichrome wire, and may be arranged in a structure wound around the liquid transfer means. The heating element may be heated by supplying an electric current, and may transfer heat to the liquid composition in contact with the heating element to heat the liquid composition. As a result, an aerosol is generated.

[0047] For example, the vaporizer 14 may also be referred to as, but is not limited to, a cartomizer or an atomizer.

[0048] Meanwhile, the aerosol generating device 1 may further include a general-purpose component in addition to the battery 11, the control unit 12, the heater 13, and the vaporizer 14. For example, the aerosol generating device 1 may include a display capable of outputting visual information and / or a motor for outputting tactile information. The aerosol generating device 1 may also include at least one sensor (such as a puff sensor, a temperature sensor, or an insertion detection sensor for an aerosol-generating article). The aerosol generating device 1 may also be manufactured to have a structure that allows the inflow of external air or the outflow of internal gas even when the cigarette 2 is inserted.

[0049] Although not shown in Fig. 1 to Fig. 3, the aerosol generating device 1 may form a system together with a separate cradle. For example, the cradle is used to charge the battery 11 of the aerosol generating device 1. Alternatively, the heater 13 heats the aerosol generating device 1 in a state where the cradle and the aerosol generating device 1 are coupled together.

[0050] The cigarette 2 may be similar to a typical combustion cigarette. For example, the cigarette 2 may be divided into a first portion including an aerosol-generating material and a second portion including a filter or the like. Alternatively, the second portion of the cigarette 2 may also include an aerosol-generating material. For example, the aerosol-generating material in the form of granules or capsules may be inserted into the second portion.

[0051] The entire first part may be inserted into the aerosol generating device 1, and the second part may be exposed to the outside. Alternatively, only a part of the first part may be inserted into the aerosol generating device 1, or the entire first part and a part of the second part may be inserted. The user inhales the aerosol while holding the second part in their mouth. At this time, the aerosol is generated by the passage of outside air through the first part, and the generated aerosol is delivered to the user's mouth through the second part.

[0052] As an example, the external air may flow in through at least one air passage formed in the aerosol generating device 1. For example, the opening and closing of the air passage formed in the aerosol generating device 1 and / or the size of the air passage may be adjusted by the user. This allows the user to adjust the amount of atomization, smoking sensation, etc. As another example, the external air may flow in to the inside of the cigarette 2 through at least one hole formed in the surface of the cigarette 2.

[0053] An example of the cigarette 2 will now be described with reference to FIGS.

[0054] 4 and 5 are diagrams showing examples of cigarettes.

[0055] 4, the cigarette 2 includes a tobacco rod 21 and a filter rod 22. With reference to FIGS. 1 to 3, the first portion described above includes the tobacco rod 21, and the second portion includes the filter rod 22.

[0056] Although the filter rod 22 is shown as a single segment in FIG. 4, this is not limiting. In other words, the filter rod 22 may be composed of multiple segments. For example, the filter rod 22 may include a segment that cools the aerosol and a segment that filters a predetermined component contained in the aerosol. Also, if necessary, the filter rod 22 may further include at least one segment that performs another function.

[0057] The cigarette 2 has a diameter in the range of 5 mm to 9 mm and a length of about 48 mm, but is not limited thereto. For example, the tobacco rod 21 may have a length of about 12 mm, the first segment of the filter rod 22 may have a length of about 10 mm, the second segment of the filter rod 22 may have a length of about 14 mm, and the third segment of the filter rod 22 may have a length of about 12 mm, but is not limited thereto.

[0058] The cigarette 2 may be wrapped by at least one wrapper 24. The wrapper 24 may have at least one hole through which external air can flow in or internal gas can flow out. As an example, the cigarette 2 may be wrapped by one wrapper 24. As another example, the cigarette 2 may be wrapped by two or more wrappers 24 one on top of the other. For example, the tobacco rod 21 may be wrapped by a first wrapper 241, and the filter rod 22 may be wrapped by wrappers 242, 243, and 244. Furthermore, the entire cigarette 2 may be wrapped again by a single wrapper 245. If the filter rod 22 is composed of a plurality of segments, each segment may be wrapped by a wrapper 242, 243, and 244.

[0059] The first and second wrappers 241 and 242 may be made of a general filter wrapping paper. For example, the first and second wrappers 241 and 242 may be made of a porous or non-porous wrapping paper. The first and second wrappers 241 and 242 may be made of oil-resistant paper and / or aluminum laminated paper wrapping material.

[0060] The third wrapper 243 may be made of hard wrapping paper. For example, the basis weight of the third wrapper 243 is within the range of 88 g / m2 to 96 g / m2, and preferably within the range of 90 g / m2 to 94 g / m2. The thickness of the third wrapper 243 is within the range of 120 μm to 130 μm, and preferably 125 μm.

[0061] The fourth wrapper 244 may be made of oil-resistant hard wrapping paper. For example, the basis weight of the fourth wrapper 244 is in the range of 88 g / m2 to 96 g / m2, and preferably in the range of 90 g / m2 to 94 g / m2. The thickness of the fourth wrapper 244 is in the range of 120 μm to 130 μm, and preferably 125 μm.

[0062] The fifth wrapper 245 may be made of a sterilized paper (MFW). Here, the sterilized paper (MFW) means a paper specially manufactured to improve tensile strength, water resistance, smoothness, etc., compared to general paper. For example, the basis weight of the fifth wrapper 245 is within a range of 57 g / m2 to 63 g / m2, and preferably 60 g / m2. In addition, the thickness of the fifth wrapper 245 is within a range of 64 μm to 70 μm, and preferably 67 μm.

[0063] A predetermined substance may be added to the fifth wrapper 245. Here, an example of the predetermined substance is silicone, but is not limited thereto. For example, silicone has properties such as heat resistance with little change due to temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency, and electrical insulation. However, any substance other than silicone that has the above-mentioned properties may be applied (or coated) to the fifth wrapper 245 without any restrictions.

[0064] The fifth trumpet 245 can prevent the cigarette 2 from burning. For example, when the tobacco rod 21 is heated by the heater 13, the cigarette 2 may burn. Specifically, when the temperature rises above the ignition point of any one of the substances contained in the tobacco rod 21, the cigarette 2 burns. Even in such a case, the fifth trumpet 245 contains a non-flammable substance, so that the cigarette 2 is prevented from burning.

[0065] Furthermore, the fifth trumpet 245 can prevent the aerosol generating device (e.g., holder) from being contaminated by a substance generated in the cigarette 2. A liquid substance may be generated in the cigarette 2 by a user's puff. For example, a liquid substance (e.g., moisture) is generated when the aerosol generated in the cigarette 2 is cooled by external air. The fifth trumpet 245 wraps the cigarette 2, thereby preventing the liquid substance generated in the cigarette 2 from leaking out of the cigarette 2.

[0066] The tobacco rod 21 includes an aerosol-generating substance. For example, the aerosol-generating substance may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. The tobacco rod 21 may also include other additive substances, such as flavoring agents, humectants, and / or organic acids. A flavoring liquid, such as menthol or a humectant, is added to the tobacco rod 21 by being sprayed onto the tobacco rod 21.

[0067] The tobacco rod 21 may be manufactured in various ways. For example, the tobacco rod 21 may be manufactured in a sheet or in a strand. The tobacco rod 21 may also be manufactured in a cut tobacco obtained by finely shredding a tobacco sheet. The tobacco rod 21 may also be surrounded by a thermally conductive material. For example, the thermally conductive material may be a metal foil such as aluminum foil, but is not limited thereto. As an example, the thermally conductive material surrounding the tobacco rod 21 may uniformly distribute the heat transferred to the tobacco rod 21 to improve the thermal conductivity applied to the tobacco rod, thereby improving the tobacco taste. The thermally conductive material surrounding the tobacco rod 21 may also function as a susceptor that is heated by an induction heater. In this case, although not shown in the drawings, the tobacco rod 21 may further include an additional susceptor in addition to the thermally conductive material surrounding the outside.

[0068] The filter rod 22 may be a cellulose acetate filter. Meanwhile, there is no limitation on the shape of the filter rod 22. For example, the filter rod 22 may be a cylindrical rod, or may be a tubular rod having a hollow inside. The filter rod 22 may also be a recessed rod. If the filter rod 22 is composed of a plurality of segments, at least one of the plurality of segments may be manufactured in a different shape.

[0069] The first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tubular structure having a hollow inside. The first segment can prevent the inner material of the tobacco rod 21 from being pushed backward when the heater 13 is inserted, and also has a cooling effect on the aerosol. The diameter of the hollow included in the first segment may be an appropriate diameter within the range of 2 mm to 4.5 mm, but is not limited thereto.

[0070] The length of the first segment may be an appropriate length within the range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first segment is 10 mm, but is not limited thereto.

[0071] The hardness of the first segment can be adjusted by adjusting the content of the plasticizer during the manufacture of the first segment. The first segment may also be manufactured by inserting a structure such as a film or tube made of the same or different material inside (e.g., hollow).

[0072] The second segment of the filter rod 22 cools the aerosol generated by the heater 13 heating the tobacco rod 21. Thus, the user can inhale the aerosol that has been cooled to an appropriate temperature.

[0073] The length or diameter of the second segment is determined in various ways depending on the shape of the cigarette 2. For example, the length of the second segment is appropriately adopted within the range of 7 mm to 20 mm. Preferably, the length of the second segment is about 14 mm, but is not limited to this.

[0074] The second segment may be made by weaving polymer fibers. In this case, the fragrance liquid may be applied to the fibers made of the polymer. Alternatively, the second segment may be produced by weaving a separate fiber to which the fragrance liquid is applied and a fiber made of the polymer together. Alternatively, the second segment may be formed by a crimped polymer sheet.

[0075] For example, the polymer may be made of a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA) and aluminum foil.

[0076] The second segment may be formed from woven polymer fibers or a crimped polymer sheet such that the second segment includes one or more longitudinally extending channels, where channel refers to a passageway through which a gas (e.g., air or aerosol) may pass.

[0077] For example, the second segment made of a crimped polymer sheet is formed from a material having a thickness of about 5 μm to about 300 μm, for example, about 10 μm to about 250 μm. The total surface area of ​​the second segment is about 300 mm2 / mm to about 1000 mm2 / mm. The aerosol cooling element is formed from a material having a specific surface area of ​​about 10 mm2 / mg to about 100 mm2 / mg.

[0078] Meanwhile, the second segment includes a thread containing a volatile flavor component, which may be, but is not limited to, menthol. For example, the thread may be loaded with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0079] The third segment of the filter rod 22 may be a cellulose acetate filter. The length of the third segment is appropriately adopted within the range of 4 mm to 20 mm. For example, the length of the third segment is about 12 mm, but is not limited thereto.

[0080] In the process of manufacturing the third segment, the third segment may be manufactured so that a flavor is generated by spraying a flavoring liquid onto the third segment. Alternatively, separate fibers coated with a flavoring liquid may be inserted into the third segment. The aerosol generated in the tobacco rod 21 is cooled by passing through the second segment of the filter rod 22, and the cooled aerosol is delivered to the user through the third segment. Therefore, when a flavoring element is added to the third segment, the effect of increasing the duration of the flavor delivered to the user is achieved.

[0081] The filter rod 22 may also include at least one capsule 23. Here, the capsule 23 functions to generate flavor or generate aerosol. For example, the capsule 23 has a structure in which a liquid containing a flavoring agent is enveloped in a coating. The capsule 23 may have a spherical or cylindrical shape, but is not limited thereto.

[0082] 5, the cigarette 3 may further include a front end plug 33. The front end plug 33 is located on one side of the tobacco rod 31 facing the filter rod 32. The front end plug 33 prevents the tobacco rod 31 from falling off to the outside, and can prevent aerosol liquefied from the tobacco rod 31 during smoking from flowing into the aerosol generating device (FIGS. 1 to 3).

[0083] Filter rod 32 may include a first segment 321 and a second segment 322, where first segment 321 corresponds to the first segment of filter rod 22 of FIG. 4 and second segment 322 corresponds to the third segment of filter rod 22 of FIG.

[0084] The diameter and overall length of the cigarette 3 correspond to those of the cigarette 2 of Figure 4. For example, but not limited to, the length of the front end plug 33 is about 7 mm, the length of the tobacco rod 31 is about 15 mm, the length of the first segment 321 is about 12 mm, and the length of the second segment 322 is about 14 mm.

[0085] The cigarette 3 may be wrapped by at least one wrapper 35. The wrapper 35 may have at least one hole formed therein through which external air can flow in or internal gas can flow out. For example, the front end plug 33 may be wrapped by a first wrapper 351, the tobacco rod 31 may be wrapped by a second wrapper 352, the first segment 321 may be wrapped by a third wrapper 353, and the second segment 322 may be wrapped by a fourth wrapper 354. Furthermore, the entire cigarette 3 may be wrapped again by a fifth wrapper 355.

[0086] Also, at least one perforation 36 may be formed in the fifth wrapper 355. For example, but not limited to, the perforation 36 is formed in the area surrounding the tobacco rod 31. The perforation 36 serves to transfer heat generated by the heater 13 shown in Figures 2 and 3 to the inside of the tobacco rod 31.

[0087] The second segment 322 may also include at least one capsule 34. Here, the capsule 34 has a function of generating a flavor or a function of generating an aerosol. For example, the capsule 34 has a structure in which a liquid containing a flavoring is enveloped in a coating. The capsule 34 may have a spherical or cylindrical shape, but is not limited thereto.

[0088] The first wrapper 351 is a typical filter wrapper with a metal foil such as aluminum foil bonded to it. For example, the total thickness of the first wrapper 351 is within a range of 45 μm to 55 μm, and preferably 50.3 μm.

[0109] The display unit 432 visually provides information about the aerosol generating device 400 to a user. For example, the information about the aerosol generating device 400 means various information such as a charging / discharging state of the battery 440 of the aerosol generating device 400, a preheating state of the heater 450, an insertion / removal state of an aerosol generating article, or a state in which the use of the aerosol generating device 400 is restricted (e.g., detection of an abnormal article), and the display unit 432 outputs the information to the outside. The display unit 432 is, for example, a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), etc. Also, the display unit 432 may be in the form of an LED light emitting element.

[0117] In one embodiment, the heater 450 may include multiple heaters. For example, the heater 450 may include a first heater for heating the cigarette and a second heater for heating the liquid.

[0118] The user input unit 460 receives information input by a user or outputs information to a user. For example, the user input unit 460 may be, but is not limited to, a key pad, a dome switch, a touch pad (contact type capacitance type, pressure type resistive film type, infrared sensing type, surface ultrasonic conduction type, integral type tension measurement type, piezoelectric effect type, etc.), a jog wheel, a jog switch, etc. Although not shown in FIG. 6, the aerosol generating device 400 may further include a connection interface such as a universal serial bus (USB) interface, etc., and may connect to other external devices through the connection interface such as the USB interface to transmit and receive information or charge the battery 440.

The memory 470 includes at least one type of storage medium, such as a flash memory type, a hard disk type, a multimedia card micro type, a card-type memory (e.g., SD or XD memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, or an optical disk. The memory 470 stores the operation time of the aerosol generating device 400, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data related to the user's smoking pattern, etc.

[0120] The communication unit 480 includes at least one component for communication with other electronic devices. For example, the communication unit 480 includes a short-range communication unit 482 and a wireless communication unit 484.

[0123] The control unit 410 controls the overall operation of the aerosol generating device 400. In one embodiment, the control unit 410 may include at least one processor. The processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable by the microprocessor is stored. It will be understood by a person skilled in the art to which this embodiment pertains that the processor may be implemented as other types of hardware.

[0124] The control unit 410 controls the temperature of the heater 450 by controlling the supply of power from the battery 440 to the heater 450. For example, the control unit 410 controls the power supply by controlling the switching of a switching element between the battery 440 and the heater 450. In another example, a heating direct circuit can also control the power supply to the heater 450 according to a control command from the control unit 410.

[0125] The control unit 410 analyzes the results sensed by the sensing unit 420 and controls subsequent processes. For example, the control unit 410 controls the power supplied to the heater 450 so that the operation of the heater 450 starts or ends based on the results sensed by the sensing unit 420. As another example, the control unit 410 controls the amount of power supplied to the heater 450 and the time for which the power is supplied so that the heater 450 is heated to a predetermined temperature or maintains an appropriate temperature based on the results sensed by the sensing unit 420.

[0126] The control unit 410 controls the output unit 430 based on the result sensed by the sensing unit 420. For example, when the number of puffs counted through the puff sensor 426 reaches a preset number, the control unit 410 may notify the user through at least one of the display unit 432, the haptic unit 434, and the audio output unit 436 that the aerosol generating device 400 will soon be shut down.

[0127] In one embodiment, the control unit 410 may control the time and / or amount of power supplied to the heater 450 depending on the state of the aerosol-generating article sensed by the sensing unit 420. For example, when the aerosol-generating article is in an overly humid state, the control unit 410 may control the time of power supply to the induction coil to increase the pre-heating time compared to when the aerosol-generating article is in a normal state.

[0128] An embodiment may also be embodied in the form of a recording medium including computer-executable instructions, such as a program module executed by a computer. A computer-readable medium may be any available medium that can be accessed by a computer, including both volatile and non-volatile media, and both separate and non-separate media.
