Mode for Carrying Out the Invention

[0022] The terms used in the embodiments are generally selected as widely as possible currently while considering the functions in the present invention, but this may vary depending on the intentions or precedents of those skilled in the art, the emergence of new technologies, etc. Also, in certain cases, there are terms arbitrarily selected by the applicant, and in such cases, the meaning thereof will be described in detail in the explanatory part of the corresponding invention. Therefore, the terms used in the present invention are not merely the names of the terms, but must be defined based on the meaning of the terms and the overall content of the present invention.

[0023] Throughout the specification, when any part "includes" any component, this means that, unless otherwise stated to the contrary, it does not exclude other components, but further includes other components. Also, terms such as "~ part" and "~ module" described in the specification mean a unit that processes at least one function or operation, and this can be implemented by hardware, software, or a combination of hardware and software.

[0024] Hereinafter, with reference to the accompanying drawings, embodiments of the present invention will be described in detail so that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement them. However, the present invention can be realized in various different forms and is not limited to the embodiments described here.

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0026] FIGS. 1 to 3 are diagrams showing an example in which a roll tobacco is inserted into an aerosol generator.

[0027] Referring to FIG. 1, the aerosol generating device 1 includes a battery 11, a control unit 12, and a heater 13. Referring to FIGS. 2 and 3, the aerosol generating device 1 further includes an atomizer 14. Also, a roll-up tobacco 2 may be inserted into the internal space of the aerosol generating device 1.

[0028] In the aerosol generating device 1 shown in FIGS. 1 to 3, the components related to the present embodiment are illustrated. Therefore, those having ordinary knowledge in the technical field related to the present embodiment can understand that, in addition to the components shown in FIGS. 1 to 3, different general-purpose components may be further included in the aerosol generating device 1.

[0029] Also, FIGS. 2 and 3 illustrate that the aerosol generating device 1 includes a heater 13, but the heater 13 may be omitted as needed.

[0030] FIG. 1 illustrates that the battery 11, the control unit 12, and the heater 13 are arranged in a row. Also, FIG. 2 illustrates that the battery 11, the control unit 12, the atomizer 14, and the heater 13 are arranged in a row. Also, FIG. 3 illustrates that the atomizer 14 and the heater 13 are 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, depending on the design of the aerosol generating device 1, the arrangements of the battery 11, the control unit 12, the heater 13, and the atomizer 14 can be changed.

[0031] When the roll-up tobacco 2 is inserted into the aerosol generating device 1, the aerosol generating device 1 can operate the heater 13 and / or the atomizer 14 to generate an aerosol. The aerosol generated by the heater 13 and / or the atomizer 14 passes through the roll-up tobacco 2 and is transmitted to the user.

[0032] If necessary, the aerosol generating device 1 can also heat the heater 13 even when the roll-up tobacco 2 is not inserted into the aerosol generating device 1.

[0033] The battery 11 supplies the electric power used for the aerosol generator 1 to operate. For example, the battery 11 supplies electric power so that the heater 13 or the vaporizer 14 can be heated, and supplies the electric power necessary for the control unit 12 to operate. Further, the battery 11 may supply the electric power necessary for a display, a sensor, a motor, etc. installed in the aerosol generator 1 to operate.

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

[0035] The control unit 12 includes at least one processor. The processor may be realized as an array of a plurality of logic gates, or may be realized as a combination of a general-purpose microprocessor and a memory storing a program executable by this microprocessor. Also, those having ordinary knowledge in the technical field to which this embodiment belongs can understand that it may be realized by another form of hardware.

[0036] The heater 13 is heated by the electric power supplied from the battery 11. For example, when a cigarette is inserted into the aerosol generator 1, the heater 13 may be disposed outside the cigarette. Therefore, the heated heater 13 can raise the temperature of the aerosol generating substance in the cigarette.

[0037] The heater 13 may be an electric resistance heater. For example, the heater 13 includes an electrically conductive track, and the heater 13 is heated when an electric current flows through the electrically conductive track. However, the heater 13 is not limited to the above-described example, and any heater that can heat to a desired temperature is applicable without limitation. Here, the desired temperature may be preset in the aerosol generating device 1, or may be set to a temperature desired by the user.

[0038] On the other hand, as a different example, the heater 13 may be an induction heating type heater. Specifically, the heater 13 may include an electrically conductive coil for heating a cigarette by induction heating, and the cigarette may include a susceptor that can be heated by the induction heating type heater.

[0039] For example, the heater 13 may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and may heat the inside or outside of the cigarette 2 according to the shape of the heating element.

[0040] Also, a plurality of heaters 13 may be arranged in the aerosol generating device 1. Here, the plurality of heaters 13 may be arranged so as to be inserted into the cigarette 2, or may be arranged outside the cigarette 2. Also, some of the plurality of heaters 13 may be arranged so as to be inserted into the cigarette 2, and the rest may be arranged outside the cigarette 2. Also, the shape of the heater 13 is not limited to the shapes shown in FIGS. 1 to 3, and may be manufactured in various shapes.

[0041] The vaporizer 14 heats the liquid phase composition to generate an aerosol, and the generated aerosol can be transmitted to the user through the cigarette 2. In other words, the aerosol generated by the vaporizer 14 moves along the air flow path of the aerosol generating device 1, and the air flow path can be configured such that the aerosol generated by the vaporizer 14 passes through the cigarette and is transmitted to the user.

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

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

[0044] For example, the liquid-phase composition may include water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. The fragrance may include, but is not limited to, menthol, peppermint, spearmint oil, and fragrance components of various fruits. The flavoring agent includes components that can provide various fragrances or flavors to the user. The vitamin mixture is a mixture in which at least one of vitamin A, vitamin B, vitamin C, and vitamin E is mixed, but is not limited thereto. Further, the liquid-phase composition may include an aerosol-forming agent such as glycerin and propylene glycol.

[0045] The liquid transfer means can transfer the liquid-phase composition of the liquid storage unit to the heating element. For example, the liquid transfer means may be, but is not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0046] The heating element is an element for heating the liquid-phase composition transferred by the liquid transfer means. For example, the heating element includes, but is not limited to, a metal heating wire, a metal hot plate, a ceramic heater, etc. Further, the heating element may be composed 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 is heated by current supply, transfers heat to the liquid composition in contact with the heating element, and can heat the liquid composition. As a result, an aerosol can be generated.

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

[0048] On the other hand, the aerosol generating device 1 may further include a general configuration 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. Further, the aerosol generating device 1 may include at least one sensor (such as a puff detection sensor, a temperature detection sensor, a roll tobacco insertion detection sensor, etc.). Further, the aerosol generating device 1 can be manufactured with a structure that allows outside air to flow in and internal gas to flow out even when the roll tobacco 2 is inserted.

[0049] Although not shown in FIGS. 1 to 3, the aerosol generating device 1 may form a system together with a separate cradle. For example, the cradle may be used to charge the battery 11 of the aerosol generating device 1. Or, the heater 13 may be heated with the cradle and the aerosol generating device 1 coupled together.

[0050] The roll tobacco 2 is similar to a general combustion-type roll tobacco. For example, the roll tobacco 2 is divided into a first part containing an aerosol generating substance and a second part containing a filter or the like. Or, the second part of the roll tobacco 2 may also contain an aerosol generating substance. For example, an aerosol generating substance made in the form of granules or capsules may be inserted into the second part.

[0051] The entire first part is inserted inside the aerosol generating device 1, and the second part is exposed to the outside. Or, only a part of the first part may be inserted inside the aerosol generating device 1, or the entire first part and a part of the second part may be inserted. The user can inhale the aerosol with the second part held in the mouth. Here, the aerosol is generated by the outside air passing through the first part, and the generated aerosol is transmitted to the user's mouth through the second part.

[0052] As an example, outside air can flow into the aerosol generator 1 through at least one air passage formed therein. For example, the opening and closing of the air passage formed in the aerosol generator 1 and / or the size of the air passage can be adjusted by the user. Therefore, the amount of smoke, the smoking sensation, etc. can be adjusted by the user. As a different example, outside air may flow into the interior of the roll-up tobacco 2 through at least one hole formed on the surface of the roll-up tobacco 2.

[0053] Hereinafter, referring to FIGS. 4 and 5, an example of the roll-up tobacco 2 will be described.

[0054] FIGS. 4 and 5 are diagrams showing an example of the roll-up tobacco.

[0055] Referring to FIG. 4, the roll-up tobacco 2 includes a tobacco rod 21 and a filter rod 22. The first part 21 described above with reference to FIGS. 1 to 3 includes the tobacco rod 21, and the second part 22 includes the filter rod 22.

[0056] In FIG. 4, the filter rod 22 is illustrated as a single segment, but is not limited thereto. In other words, the filter rod 22 may be composed of a plurality of segments. For example, the filter rod 22 may include a segment for cooling the aerosol and a segment for filtering a predetermined component contained in the aerosol. Further, if necessary, the filter rod 22 may further include at least one segment for performing other functions.

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

[0058] The wrapped cigarette 2 is wrapped by at least one wrapper 24. At least one hole may be formed in the wrapper 24 for outside air to flow in or internal gas to flow out. As an example, the wrapped cigarette 2 may be wrapped by one wrapper 24. As a different example, the wrapped cigarette 2 may be repeatedly wrapped by two or more wrappers 24. For example, the tobacco rod 21 may be wrapped by the first wrapper 241, and the filter rod 22 may be wrapped by the wrappers 242, 243, 244. Then, the whole wrapped cigarette 2 may be re-wrapped by a single wrapper 245. If the filter rod 22 is composed of multiple segments, each segment may be wrapped by the wrappers 242, 243, 244.

[0059] The first wrapper 241 and the second wrapper 242 can be manufactured with common filter paper. For example, the first wrapper 241 and the second wrapper 242 may be porous wrapping paper or non-porous wrapping paper. Also, the first wrapper 241 and the second wrapper 242 may be manufactured with oil-resistant papers and / or aluminum-aluminum composite paper packaging materials.

[0060] The third wrapper 243 may be manufactured with hard wrapping paper. For example, the grammage of the third wrapper 243 is included within the range of about 88 g / m 2 ~ about 96 g / m 2 and preferably within the range of about 90 g / m 2 ~ about 94 g / m 2 It may also be included. Also, the thickness of the third wrapper 243 is included within the range of about 120 um to about 130 um and preferably may be about 125 um.

[0061] The fourth wrapper 244 may be manufactured with oil-resistant hard wrapping paper. For example, the grammage of the fourth wrapper 244 is included within the range of about 88 g / m 2 ~ about 96 g / m 2 and preferably within the range of about 90 g / m 2 ~ about 94 g / m 2It may be included within the range. Also, the thickness of the fourth wrapper 244 may be included within the range of about 120 μm to about 130 μm, and preferably may be about 125 μm.

[0062] The fifth wrapper 245 may be made of sterilized paper (MFW). Here, sterilized paper (MFW) means paper that is specially manufactured so that its tensile strength, water resistance, smoothness, etc. are enhanced compared to ordinary paper. For example, the basis weight of the fifth wrapper 245 is within the range of about 57 g / m 2 ~about 63 g / m 2 and may preferably be about 60 g / m 2 Also, the thickness of the fifth wrapper 245 may be included within the range of about 64 μm to about 70 μm, and preferably may be about 67 μm.

[0063] A predetermined substance can be added to the fifth wrapper 245. Here, an example of the predetermined substance is silicon, but it is not limited thereto. For example, silicon has properties such as heat resistance with little change due to temperature, oxidation resistance that is not oxidized, resistance to various chemicals, water repellency to water, or electrical insulation. However, even if it is not silicon, as long as it is a substance having the above-described properties, it can be applied (or coated) to the fifth wrapper 245 without limitation.

[0064] The fifth wrapper 245 can prevent the development of combustion of the wrapped cigarette 2. For example, if the tobacco rod 21 is heated by the heater 13, the wrapped 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 wrapped cigarette 2 burns. Even in such a case, since the fifth wrapper 245 contains a non-combustible substance, the development of combustion of the wrapped cigarette 2 is prevented.

[0065] In addition, the fifth wrapper 245 can prevent the aerosol generating device from being contaminated by substances generated by the rolled tobacco 2. Depending on the user's puff, a liquid substance is generated within the rolled tobacco 2. For example, when the aerosol generated by the rolled tobacco 2 is cooled by the outside air, a liquid substance (such as moisture, etc.) is generated. By wrapping the rolled tobacco 2 with the fifth wrapper 245, it is possible to prevent the liquid substance generated within the rolled tobacco 2 from leaking to the outside of the rolled tobacco 2.

[0066] The tobacco rod 21 contains aerosol generating substances. For example, the aerosol generating substances include, but are not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Further, the tobacco rod 21 can contain other additive substances such as flavoring agents, wetting agents, and / or organic acids. Also, a flavoring liquid such as menthol or a humectant may be added to the tobacco rod 21 by spraying it onto the tobacco rod 21.

[0067] The tobacco rod 21 can be manufactured in various ways. For example, the tobacco rod 21 may be manufactured from a sheet or a strand. Also, the tobacco rod 21 may be manufactured from cut tobacco in which the tobacco sheet is finely cut. Further, the tobacco rod 21 may be surrounded by a heat conductive substance. For example, the heat conductive substance may be a metal foil such as aluminum foil, but is not limited thereto. As an example, the heat conductive substance wrapping the tobacco rod 21 can evenly disperse the heat transferred to the tobacco rod and improve the thermal conductivity applied to the tobacco rod, thereby improving the taste of the tobacco. Also, the heat conductive substance wrapping the tobacco rod 21 is heated by an induction heating heater and functions as a susceptor. Here, although not shown in the drawings, the tobacco rod 21 may further include an additional susceptor in addition to the heat conductive substance wrapping the outside.

[0068] The filter rod 22 may be an acetyl cellulose filter. On the other hand, there is no limitation on the shape of the filter rod 22. For example, the filter rod 22 may be a cylindrical type rod, or may be a tube type rod including a hollow portion inside. Also, the filter rod 22 may be a recess type 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 an acetyl cellulose filter. For example, the first segment may be a tubular structure including a hollow inside. When the heater 13 is inserted by the first segment, it is possible to prevent the phenomenon that the internal substance of the tobacco rod 21 shifts backward, and a cooling effect of the aerosol can also occur. The diameter of the hollow included in the first segment adopts an appropriate diameter within the range of about 2 mm to about 4.5 mm, but is not limited thereto.

[0070] The length of the first segment adopts an appropriate length within the range of about 4 mm to about 30 mm, but is not limited thereto. Preferably, the length of the first segment is about 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. Also, the first segment may be manufactured by inserting a structure such as a film or a tube of the same or release material inside (for example, a hollow).

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

[0073] The length or diameter of the second segment can be determined in various ways according to the form of the wrapped tobacco 2. For example, the length of the second segment may be appropriately adopted within the range of about 7 mm to about 20 mm. Preferably, the length of the second segment is about 14 mm, but is not limited thereto.

[0074] The second segment can be manufactured by weaving polymer fibers. In this case, a flavoring liquid may be applied to the fibers made of the polymer. Alternatively, the second segment may be manufactured by weaving together separately fiber coated with the flavoring liquid and fibers made of the polymer. Alternatively, the second segment may be formed by a wound polymer sheet.

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

[0076] By being formed by the woven polymer fibers or the wound polymer sheet of the second segment, the second segment may include one or more channels extending in the longitudinal direction. Here, the channel means a passage through which gas (for example, air or aerosol) passes.

[0077] For example, the second segment made of a wound polymer sheet may be formed from a material having a thickness between about 5 μm and about 300 μm, for example, between about 10 μm and about 250 μm. Also, the total surface area of the second segment may be between about 300 mm 2 / mm and about 1000 mm 2 / mm. Also, the aerosol cooling element may be formed from a material having a specific surface area between about 10 mm 2 / mg and about 100 mm 2 / mg.

[0078] On the other hand, the second segment may include a thread containing a volatile flavor component. Here, the volatile flavor component may be menthol, but is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide about 1.5 mg or more of menthol to the second segment.

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

[0080] In the process of manufacturing the third segment, it may be manufactured such that a flavor is generated by injecting a flavoring liquid into the third segment. Alternatively, a separate fiber coated with the flavoring liquid may be inserted into the third segment. The aerosol generated by the tobacco rod 21 is cooled by passing through the second segment of the filter rod 22, and the cooled aerosol is transmitted to the user through the third segment. Therefore, when a flavoring element is added to the third segment, an effect of enhancing the persistence of the flavor transmitted to the user occurs.

[0081] Further, the filter rod 22 may include at least one capsule 23. Here, the capsule 23 may perform a function of generating a flavor or a function of generating an aerosol. For example, the capsule 23 may have a structure in which a liquid containing a fragrance is wrapped with a film. The capsule 23 may have a spherical or cylindrical shape, but is not limited thereto.

[0082] Referring to FIG. 5, the wrapped tobacco 3 further includes a shear plug 33. The shear plug 33 is disposed on one side of the tobacco rod 31 facing the filter rod 32. The shear plug 33 prevents the tobacco rod 31 from detaching externally and prevents the aerosol liquefied from the tobacco rod 31 during smoking from flowing into the aerosol generating device (for example, FIGS. 1 to 3).

[0083] The filter rod 32 includes a first segment 321 and a second segment 322. Here, the first segment 321 corresponds to the first segment of the filter rod 22 shown in FIG. 4, and the second segment 322 corresponds to the third segment of the filter rod 22 shown in FIG. 4.

[0084] The diameter and the total length of the wrapped cigarette 3 correspond to the diameter and the total length of the wrapped cigarette 2 shown in FIG. 4. For example, the length of the shear plug 33 may be about 7 mm, the length of the tobacco rod 31 may be about 15 mm, the length of the first segment 321 may be about 12 mm, and the length of the second segment 322 may be about 14 mm, but it is not limited thereto.

[0085] The wrapped cigarette 3 is wrapped by at least one wrapper 35. At least one hole through which outside air flows in or internal gas flows out can be formed in the wrapper 35. For example, the shear plug 33 is wrapped by the first wrapper 351, the tobacco rod 31 is wrapped by the second wrapper 352, the first segment 321 is wrapped by the third wrapper 353, and the second segment 322 is wrapped by the fourth wrapper 354. Then, the entire wrapped cigarette 3 can be re-wrapped by the fifth wrapper 355.

[0086] Also, at least one perforation 356 can be formed in the fifth wrapper 355. For example, the perforation 356 is formed in the region wrapping the tobacco rod 31, but is not limited thereto. The perforation 356 serves to transfer the heat generated by the heater 13 shown in FIGS. 2 and 3 to the inside of the tobacco rod 31.

[0087] Also, the second segment 322 may include at least one capsule 34. Here, the capsule 34 may perform a function of generating a fragrance or a function of generating an aerosol. For example, the capsule 34 may have a structure in which a liquid containing a fragrance is wrapped by a film. The capsule 34 has a spherical or cylindrical shape, but is not limited thereto.

[0088] The first wrapper 351 may be a general filter wrapping paper with a metal foil such as aluminum foil bonded thereto. For example, the overall thickness of the first wrapper 351 may be included within the range of about 45 μm to about 55 μm, and preferably may be about 50.3 μm. Also, the thickness of the metal foil of the first wrapper 351 may be included within the range of about 6 μm to about 7 μm, and preferably may be about 6.3 μm. Also, the weight of the first wrapper 351 is about 50 g / m 2 ~about 55 g / m 2 and may be preferably included within the range of about 53 g / m 2 and may be preferably about 53 g / m.

[0089] The second wrapper 352 and the third wrapper 353 are made of a general filter wrapping paper. For example, the second wrapper 352 and the third wrapper 353 may be a porous wrapping paper or a non-porous wrapping paper.

Since the function of the angle sensor can be intuitively inferred by those skilled in the art from its name, a specific description thereof is omitted.

[0108] The output unit 430 outputs information regarding the state of the aerosol generator 400 and provides it to the user. The output unit 430 includes at least one of a display unit 432, a haptic unit 434, and an acoustic output unit 436, but is not limited thereto. When the display unit 432 and the touch pad form a layer structure and are configured as a touch screen, the display unit 432 may be used as an input device in addition to an output device.

[0109] The display unit 432 can visually provide information regarding the aerosol generator 400 to the user. For example, the information regarding the aerosol generator 400 means various information such as the charging / discharging state of the battery 440 of the aerosol generator 400, the preheating state of the heater 450, the insertion / removal state of the aerosol article, or the state in which the use of the aerosol generator 400 is restricted (for example, detection of an abnormal article), and the display unit 432 may output the information to the outside. The display unit 432 may be, for example, a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), or the like. Further, the display unit 432 may be in the state of an LED light emitting element.

[0110] The haptic unit 434 can convert an electrical signal into a mechanical stimulus or an electrical stimulus and provide information regarding the aerosol generator 400 to the user tactilely. For example, the haptic unit 434 may include a motor, a piezoelectric element, or an electrical stimulation device.

[0111] The acoustic output unit 436 can aurally provide information regarding the aerosol generator 400 to the user. For example, the acoustic output unit 436 can convert an electrical signal into an acoustic signal and output it to the outside.

[0112] The battery 440 supplies the power used for the aerosol generator 400 to operate. The battery 440 can supply power so that the heater 450 can be heated. Also, the battery 440 supplies the power necessary for the operation of different components (for example, the detection unit 420, the output unit 430, the user input unit 460, the memory 470, and the communication unit 480) provided in the aerosol generator 400. The battery 440 may be a rechargeable battery or a disposable battery. For example, the battery 440 may be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0113] The heater 450 is supplied with power from the battery 440 and heats the aerosol generating substance. Although not shown in FIG. 6, the aerosol generator 400 may further include a power conversion circuit (for example, a DC / DC converter) that converts the power of the battery 440 and supplies it to the heater 450. Also, when the aerosol generator 400 generates aerosol by an induction heating method, the aerosol generator 400 may further include a DC / AC converter that converts the DC power supply of the battery 440 into an AC power supply.

[0114] The control unit 410, the detection unit 420, the output unit 430, the user input unit 460, the memory 470, and the communication unit 480 can be powered by the battery 440 and perform their functions. Although not shown in FIG. 6, the aerosol generator 400 may further include a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the battery 440 and supplies it to each component.

[0115] In one embodiment, the heater 450 may be formed of any suitable electrically resistive material. For example, suitable electrically resistive materials may include metals or metal alloys such as titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, etc., but are not limited thereto. Further, the heater 450 may be realized in a metal wire, a metal plate with an electrically conductive track disposed thereon, a ceramic heating element, etc., but is not limited thereto.

[0116] In one embodiment, the heater 450 may be an induction heating type heater. For example, the heater 450 may generate heat through a magnetic field applied by a coil and include a susceptor for heating the aerosol generating substance.

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

[0118] The user input unit 460 receives information input from the user or outputs information to the user. For example, the user input unit 460 includes a keypad, a dome switch, a touch pad (capacitive touch type, pressure resistive film type, infrared detection type, surface acoustic wave conduction type, integral tension measurement type, piezo effect type, etc.), a jog wheel, a jog switch, etc., but is not limited thereto. Also, although not shown in FIG. 6, the aerosol generating device 400 further includes a connection interface such as a USB (universal serial bus) interface, and is connected to other external devices via a connection interface such as a USB interface to transmit and receive information or to charge the battery 440.

[0119] Memory 470 may store data processed by control unit 410 and data to be processed as hardware for storing various types of data processed within aerosol generator 400. Memory 470 may include 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 RAM (random access memory), an SRAM (static random access memory), a ROM (read-only memory), an EEPROM (electrically erasable programmable read-only memory), a PROM (programmable read-only memory), a magnetic memory, a magnetic disk, or an optical disk. Memory 470 may store data such as the operation time of aerosol generator 400, the maximum puff count, the current puff count, at least one temperature profile, and data regarding the user's smoking pattern.

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

[0121] Short-range wireless communication unit 482 includes, but is not limited to, a Bluetooth (registered trademark) communication unit, a BLE (Bluetooth (registered trademark) Low Energy) communication unit, a Near Field Communication unit, a WLAN (Wi-Fi) communication unit, a Zigbee (registered trademark) communication unit, an infrared (IrDA, infrared Data Association) communication unit, a WFD (Wi-Fi Direct) communication unit, a UWB (ultra wideband) communication unit, an Ant+ communication unit, etc.

[0122] The wireless communication unit 484 includes, but is not limited to, a cellular network communication unit, an Internet communication unit, a computer network (e.g., LAN or WAN) communication unit, etc. The wireless communication unit 484 can identify and authenticate the aerosol generator 400 within the communication network using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)).

[0123] The control unit 410 controls the overall operation of the aerosol generator 400. In one embodiment, the control unit 410 may include at least one processor. The processor may be implemented as an array of multiple logic gates and can be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Also, those with ordinary knowledge in the technical field to which this embodiment belongs will understand that it can be implemented in other forms of hardware.

[0124] The control unit 410 can control 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 can control the power supply by controlling the switching of a switching element between the battery 440 and the heater 450. As a different example, according to a control command of the control unit 410, a direct heating circuit may control the power supply to the heater 450.

[0125] The control unit 410 analyzes the results detected by the detection unit 420 and then controls the subsequent processes. For example, the control unit 410 can control the power supplied to the heater 450 so that the operation of the heater 450 is started or terminated based on the results detected by the detection unit 420. As a different example, the control unit 410 can control the amount of power supplied to the heater 450 and the time during which the power is supplied so that the heater 450 can be heated to a predetermined temperature or maintain an appropriate temperature based on the results detected by the detection unit 420.

[0126] Based on the results detected by the detection unit 420, the control unit 410 can control the output unit 430. For example, when the puff count counted via the puff sensor 426 reaches a preset number of times, the control unit 410 can notify the user that the aerosol generator 400 will end soon via at least one of the display unit 432, the haptic unit 434, and the acoustic output unit 436.

[0127] In one embodiment, the control unit 410 can control the power supply time and / or the power supply amount to the heater 450 according to the state of the aerosol generating article detected by the detection unit 420. For example, when the aerosol generating article is in a clasped state, the control unit 410 can control the power supply time to the induction coil and increase the preheating time compared to when the aerosol generating article is in a normal state.

[0128] One embodiment may also be implemented in the form of a recording medium including computer-executable instructions such as program modules executed by a computer. The computer-readable recording medium may be any usable medium accessed by a computer, including all volatile and non-volatile media, removable and non-removable media. Also, the computer-readable recording medium can include all computer storage media and communication media. The computer storage media may include all volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information such as computer-readable instructions, data structures, program modules, or other data. The communication media typically includes modulated data signals such as computer-readable instructions, data structures, program modules, and other data, or other transmission mechanisms, and includes any information transmission medium.

[0129] The "aerosol generating substance" described in this document means a substance capable of generating an aerosol. The aerosol may contain volatile compounds. The aerosol generating substance may be in a solid or liquid phase. For example, the solid aerosol generating substance may include solid substances based on tobacco raw materials such as sheet tobacco, cut tobacco, and reconstituted tobacco, and the liquid aerosol generating substance may include liquid compositions based on nicotine, tobacco extracts, and / or various flavoring agents. The aerosol generating substance may contain an aerosol forming agent to stably form significant smoke and / or aerosol.

[0130] The "aerosol generating device" described in this document means a device that generates an aerosol using an aerosol generating article to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth.

[0131] The "upstream" or "upstream direction" described in this document means the direction away from the user's mouth, and the "downstream" or "downstream direction" means the direction approaching the user's mouth. The terms upstream and downstream are used to describe the relative positions of the elements constituting the aerosol generating article.

[0132] The "puff" described in this document means the user's inhalation. Inhalation means the situation of drawing in through the user's mouth or nose into the user's oral cavity, nasal cavity, or lungs.

[0133] The "longitudinal direction" described in this document means the direction corresponding to the longitudinal axis of the aerosol generating article.

[0134] Figure 7 is a diagram of an aerosol generating article according to an embodiment, and Figure 8 is a diagram schematically showing a cross-section of a capsule according to an embodiment.

[0135] Referring to Figures 7 and 8, the aerosol generating article 5 includes a first segment 51, a second segment 52, a third segment 53, and a fourth segment 54 from downstream to upstream.

[0136] The first segment 51 includes a filter 511. For example, the filter 511 may include an acetyl cellulose filter. In one embodiment, the first segment 51 may not include a hollow portion.

[0137] The second segment 52 includes a medium 521. For example, the medium may include an aerosol generating substance, a fragrance substance, and / or any substance suitable for generating other aerosols. The aerosol generating substance may include, for example, at least one of shredded tobacco, sheet tobacco, and reconstituted tobacco. In any embodiment, 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.

[0138] In one embodiment, the second segment 52 includes a capsule 522. The capsule 522 can be configured to melt within a defined temperature range. The capsule 522 may be at least partially surrounded by the medium 521. In any embodiment, the capsule 522 may be embedded in the medium 521. The capsule 522 includes a core 5221 and a shell 5222 surrounding the core 5221.

[0139] In one embodiment, the core 5221 and the shell 5222 may form a capsule 522 having at least a partially curved surface. In any embodiment, the core 5221 and the shell 5222 may form a capsule 522 having a substantially circular or elliptical cross-section. In one embodiment, the core 5221 and the shell 5222 may form a capsule 522 having any suitable shape.

[0140] In one embodiment, the core 5221 may contain a basic substance. The basic substance can convert one form of aerosol-generating substance in the medium 521 into any different form of aerosol-generating substance suitable for the user to inhale. For example, as shown in FIG. 9, the basic substance can promote the transfer to the user in the form of "free nicotine" having sufficient volatility at a relatively low temperature by breaking the chemical bonds in the substance in the form of nicotine salt.

[0141] An aerosol having sufficient volatility at a relatively low temperature can reduce the unpleasant irritation to the user when transferred to the user and increase the sense of satisfaction for the user to inhale. Considering that the aerosol is generated at a relatively low temperature, the amount of aerosol transferred to the user can be increased. Also, since the aerosol can be generated at a relatively low temperature, the initial preheating temperature and / or operating temperature of the device (e.g., the aerosol generating device 1 in FIGS. 1 to 3) to which the aerosol generating article 5 is applied can be reduced. Further, by making the medium 521 in a relatively high pH environment, the chemical damage to the wrapper (e.g., the second wrapper 552 and / or the fifth wrapper 555) wrapping the medium 521 can be reduced.

[0142] In one embodiment, the basic substance may include at least one of alkali metal carbonates, alkaline earth metal carbonates, alkali metal bicarbonates, alkaline earth metal bicarbonates, alkali metal hydroxides, alkaline earth metal hydroxides, alkali metal phosphates, alkaline earth metal phosphates, alkaline earth metal phosphates, alkali metal monohydrogen phosphates, and alkaline earth metal monohydrogen phosphates.

[0143] In any embodiment, the basic substance may include at least one of alkali metal carbonates, alkaline earth metal carbonates, alkaline earth metal bicarbonates, and alkali metal phosphates.

[0146] In one embodiment, the basic substance may include a substance that is substantially water-soluble at about 25°C.

[0147] In one embodiment, the basic substance may be about 12 wt% or less, about 11 wt% or less, about 10 wt% or less, about 9 wt% or less, or about 8 wt% or less based on 100 wt% of the medium 521.

[0148] In one embodiment, the core 5221 may have a diameter or width of about 2.0 mm or more, about 2.5 mm or more, about 3.0 mm or more, about 3.5 mm or more, about 4.5 mm or more, about 5.0 mm or more, or about 5.5 mm or more. In one embodiment, the core 5221 may have a diameter or width of about 7.0 mm or less, 6.5 mm or less, 6.0 mm or less, 5.5 mm or less, 5.0 mm or less, 4.5 mm or less, 4.0 mm or less, 3.5 mm or less, or 3.0 mm or less.

[0149] In one embodiment, the shell 5222 may include wax. In some embodiments, the shell 5222 may include an animal or fat-soluble wax. For example, the shell 5222 may include cocoa butter, shea butter, and / or a combination thereof.

[0150] In some embodiments, the shell 5222 may include a wax indicating plant origin. For example, the shell 5222 may include carnauba wax, candelilla wax, castor wax, ouricury wax, and / or combinations thereof.

[0151] In some embodiments, the shell 5222 may include soy wax, bees wax, palm wax, paraffin wax, and / or combinations thereof.

[0152] In one embodiment, the shell 5222 may include a water-soluble polymer. As an example, the shell 5222 may include at least one of water-soluble hydrocolloids including gelatin, agar, carrageenan, alginic acid, and pectin, gums including gellan gum, starches including potato starch and corn starch, and starch derivatives including dextrin, maltodextrin, and cyclodextrin. In any example, the shell 5222 may include gelatin, agar, and / or combinations thereof. In any example, the shell 5222 may include at least one of cellulose derivatives such as hydroxypropylmethylcellulose (HPMC), hydroxypropylcellulose (HPC), methylcellulose (MC), carboxymethylcellulose (CMC), polyvinyl alcohol, and polyol.

[0153] In one embodiment, the shell 5222 may include a substance having a melting point of about 25°C or higher, about 30°C or higher, about 35°C or higher, about 40°C or higher, about 45°C or higher, about 50°C or higher, about 55°C or higher, about 60°C or higher, about 65°C or higher, about 70°C or higher, about 75°C or higher, about 80°C or higher, about 85°C or higher, about 90°C or higher, about 95°C or higher, about 100°C or higher, about 105°C or higher, about 110°C or higher, about 115°C or higher, about 120°C or higher, or about 125°C or higher. In any embodiment, the shell 5222 may include a substance having a melting point of about 40°C or higher. Since the shell 5222 does not substantially melt at room temperature, the substance of the core 5221 surrounded by the shell 5222 can be protected. Substantially maintaining the pre-use form of the capsule 522 can contribute to the storability of the capsule 522.

[0154] In one embodiment, the shell 5222 may include a substance having a melting point of about 180°C or lower, about 175°C or lower, about 170°C or lower, about 165°C or lower, about 160°C or lower, about 155°C or lower, about 150°C or lower, about 145°C or lower, about 140°C or lower, about 135°C or lower, about 130°C or lower, about 125°C or lower, about 120°C or lower, about 115°C or lower, about 110°C or lower, about 105°C or lower, about 100°C or lower, about 95°C or lower, about 90°C or lower, about 85°C or lower, about 80°C or lower, about 75°C or lower, about 70°C or lower, about 65°C or lower, about 60°C or lower, about 55°C or lower, about 50°C or lower, or about 45°C or lower. In any embodiment, the shell 5222 may include a substance having a melting point of about 130°C or lower. In any embodiment, the shell 5222 may include a substance having a melting point of about 80°C or lower. The melting of the shell 5222 at the above temperatures can contribute to the smooth release of the substance forming the core 5221 in a desired environment (e.g., a relatively low-temperature environment) where the capsule 522 can be applied.

[0155] In one embodiment, the shell 5222 may have a thickness of 0.1 mm or more, about 0.2 mm or more, about 0.3 mm or more, about 0.4 mm or more, about 0.5 mm or more, about 0.6 mm or more, about 0.7 mm or more, or about 0.8 mm or more.

[0156] In one embodiment, the shell 5222 may have a thickness of about 1.5 mm or less, about 1.4 mm or less, about 1.3 mm or less, about 1.2 mm or less, about 1.1 mm or less, about 1.0 mm or less, or about 0.9 mm or less.

[0157] In one embodiment, the capsule 522 may have a crushing strength of about 0.5 kgf or more, about 0.6 kgf or more, about 0.7 kgf or more, about 0.8 kgf or more, about 0.9 kgf or more, about 1.0 kgf or more, about 1.1 kgf or more, about 1.2 kgf or more, about 1.3 kgf or more, or about 1.4 kgf or more. In any embodiment, the capsule 522 may have a crushing strength of about 1.0 kgf or more. If the crushing strength of the capsule 522 is low, it is disadvantageous for the storage property of the capsule 522, so the melting of the shell 5222 and the release of the core 5221 in a desired environment cannot be expected.

[0158] In one embodiment, the capsule 522 may have a crushing strength of about 3.0 kgf or less, about 2.9 kgf or less, about 2.8 kgf or less, about 2.7 kgf or less, about 2.6 kgf or less, about 2.5 kgf or less, about 2.4 kgf or less, about 2.3 kgf or less, about 2.2 kgf or less, about 2.1 kgf or less, about 2.0 kgf or less, about 1.9 kgf or less, or about 1.8 kgf or less. In any embodiment, the capsule 522 may have a crushing strength of about 2.5 kgf or less. In any application example, the user can also break the capsule 522 to release the core 5221.
