Mode for Carrying Out the Invention

[0021] In the embodiments, the terms used are selected as general terms that are currently widely used as much as possible while considering the functions in the embodiments. However, this may change 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 description part of the corresponding invention. Therefore, the terms used in the present invention should be defined based not on just the names of the terms but on the meanings the terms have and the content throughout the present invention.

[0022] Throughout the specification, when a certain part "includes" a certain component, this means that, unless otherwise stated to the contrary, it does not exclude other components but may further include other components. Furthermore, terms such as "section" and "module" described in the specification mean units that process at least one function or operation, and these may be realized by hardware or software, or a combination of hardware and software.

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0024] Figures 1 to 3 are diagrams showing an example in which a roll-up tobacco is inserted into an aerosol generating device.

[0025] 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.

[0026] In the aerosol generating device 1 shown in FIGS. 1 to 3, components related to the present embodiment are shown. 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, other general-purpose components are further included in the aerosol generating device 1.

[0027] Furthermore, FIGS. 2 and 3 show that the heater 13 is included in the aerosol generating device 1, but the heater 13 may be omitted as necessary.

[0028] FIG. 1 shows that the battery 11, the control unit 12, and the heater 13 are arranged in a row. Also, FIG. 2 shows that the battery 11, the control unit 12, the atomizer 14, and the heater 13 are arranged in a row. Furthermore, FIG. 3 shows 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 may be changed.

[0029] 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.

[0030] Even when the roll-up tobacco 2 is not inserted into the aerosol generating device 1 as necessary, the aerosol generating device 1 can heat the heater 13.

[0031] The battery 11 supplies the electric power used for the operation of the aerosol generating device 1. For example, the battery 11 can supply electric power so that the heater 13 or the vaporizer 14 is heated, and can supply the electric power necessary for the operation of the control unit 12. Further, the battery 11 can supply the electric power necessary for the operation of a display, a sensor, a motor, etc. provided in the aerosol generating device 1.

[0032] The control unit 12 generally controls the operation of the aerosol generating device 1. Specifically, the control unit 12 controls not only the battery 11, the heater 13, and the vaporizer 14, but also the operation of other components included in the aerosol generating device 1. Further, the control unit 12 may check the state of each component of the aerosol generating device 1 and determine whether the aerosol generating device 1 is in an operable state.

[0033] The control unit 12 includes at least one processor. The processor may be realized by an array of a large number of logic gates, or may be realized by 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 different forms of hardware.

[0034] The heater 13 can be heated by the electric power supplied from the battery 11. For example, when a cigarette is inserted into the aerosol generating device 1, the heater 13 can be located outside the cigarette. Therefore, the heated heater 13 can raise the temperature of the aerosol generating substance in the cigarette.

[0035] The heater 13 may be an electric resistance heater. For example, the heater 13 may include an electrically conductive track, and the heater 13 can be heated by passing an electric current 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 already be set in the aerosol generator 1, or may be set to a desired temperature by the user.

[0036] On the other hand, as another example, the heater 13 can be an induction heating type heater. Specifically, the heater 13 can include an electrically conductive coil for heating the cigarette by induction heating, and the cigarette can include a susceptor that can be heated by the induction heating type heater.

[0037] For example, the heater 13 can include heating elements having various shapes. For example, the heating element may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and the inside or outside of the rolled cigarette 2 can be heated by the pattern of the heating element.

[0038] Also, a plurality of heaters 13 may be arranged in the aerosol generator 1. At this time, the plurality of heaters 13 may be arranged so as to be inserted inside the rolled cigarette 2, or may be arranged outside the rolled cigarette 2. Further, a part of the plurality of heaters 13 may be arranged so as to be inserted inside the rolled cigarette 2, and the rest may be arranged outside the rolled cigarette 2. Also, the shape of the heater 13 is not limited to the shapes shown in FIGS. 1 to 3, and can be manufactured in various shapes.

[0039] The vaporizer 14 can heat the liquid composition to generate an aerosol, and the generated aerosol can be transmitted to the user through the rolled cigarette 2. In other words, the aerosol generated by the vaporizer 14 can move along the air flow path of the aerosol generator 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.

[0040] For example, the vaporizer 14 can include, but is not limited to, a liquid storage part, a liquid delivery means, and a heating element. For example, the liquid storage part, the liquid delivery means, and the heating element may be included in the aerosol generator 1 as independent modules.

[0041] The liquid storage part 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 part may be made to be detachable from the vaporizer 14, or may be made integrally with the vaporizer 14.

[0042] For example, the liquid composition can include water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. The fragrance can include, but is not limited to, menthol, peppermint, spearmint oil, various fruit flavor components, etc. The flavoring agent can include components that can provide various fragrances or flavors to the user. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. Also, the liquid composition can include an aerosol-forming agent such as glycerin and propylene glycol.

[0043] The liquid delivery means can deliver the liquid composition in the liquid storage part to the heating element. For example, the liquid delivery means may be a wick such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, etc., but is not limited thereto.

[0044] The heating element is an element for heating the liquid composition transmitted by the liquid transmission means. For example, the heating element may be, 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 transmission means. The heating element can be heated by supplying an electric current, and can transfer heat to the liquid composition in contact with the heating element to heat the liquid composition. As a result, an aerosol can be generated.

[0045] For example, the vaporizer 14 is called a cartomizer or an atomizer, but is not limited thereto.

[0046] On the other hand, the aerosol generating device 1 can 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 can include a display capable of outputting visual information and / or a motor for outputting tactile information. Further, the aerosol generating device 1 can include at least one sensor (such as a puff sensing sensor, a temperature sensing sensor, a cigarette insertion sensing sensor, etc.). Furthermore, the aerosol generating device 1 can be manufactured in a structure in which external air flows in or internal gas flows out even when the wrapped cigarette 2 is inserted.

[0047] 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 is used for charging the battery 11 of the aerosol generating device 1. Or, the heater 13 may be heated in a state where the cradle and the aerosol generating device 1 are coupled.

[0048] The wrapped cigarette 2 can be similar to a general combustion-type cigarette. For example, the wrapped cigarette 2 can be 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 wrapped cigarette 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.

[0049] The entire first part is inserted inside the aerosol generator 1, and the second part can be exposed to the outside. Alternatively, only a part of the first part may be inserted inside the aerosol generator 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 bitten by the mouth. At this time, 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.

[0050] As an example, the outside air can flow into the aerosol generator 1 through at least one air passage formed in the aerosol generator 1. 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. Thereby, the atomization amount, the smoking feeling, etc. can be adjusted by the user. As another example, the outside air may flow into the inside of the cigarette 2 through at least one hole formed on the surface of the cigarette 2.

[0051] Hereinafter, an example of the cigarette 2 will be described with reference to FIGS. 4 and 5.

[0052] FIGS. 4 and 5 are diagrams showing an example of a cigarette.

[0053] Referring to FIG. 4, the cigarette 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.

[0054] In FIG. 4, the filter rod 22 is shown as a single segment, but it 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 can 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 can further include at least one segment for performing other functions.

[0055] The diameter of the wrapped cigarette 2 is in the range of 5 mm to 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.

[0056] The wrapped cigarette 2 can be wrapped by at least one wrapper 24. At least one hole can be formed in the wrapper 24 for external air to flow in or internal gas to flow out. As an example, the wrapped cigarette 2 can be wrapped by one wrapper 24. As another example, the wrapped cigarette 2 may be superposed and wrapped by two or more wrappers 24. For example, the tobacco rod 21 can be wrapped by the first wrapper 241, and the filter rod 22 can be wrapped by the wrappers 242, 243, and 244. Also, the whole wrapped cigarette 2 can be repackaged by a single wrapper 245. If the filter rod 22 is composed of a plurality of segments, each segment can be wrapped by the wrappers 242, 243, and 244.

[0057] The first wrapper 241 and the second wrapper 242 can be made of a general filter wrapping 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 can be made of oil-resistant papers and / or aluminum composite paper packaging agents.

[0058] The third wrapper 243 can be made of hard wrapping paper. For example, the basis weight of the third wrapper 243 may be included in the range of 88 g / m 2 ~96 g / m 2 and preferably 90 g / m 2 ~94 g / m 2It may be included within the range. Also, the thickness of the third wrapper 243 may be included within the range of 120 μm to 130 μm, and preferably may be 125 μm.

[0059] The fourth wrapper 244 can be made of oil-resistant hard tissue paper. For example, the basis weight of the fourth wrapper 244 is 88 g / m 2 ~96 g / m 2 It may be included within the range, and preferably may be 90 g / m 2 ~94 g / m 2 It may be included within the range. Also, the thickness of the fourth wrapper 244 may be included within the range of 120 μm to 130 μm, and preferably may be 125 μm.

[0060] The fifth wrapper 245 can be made of sterilized paper (MFW). Here, sterilized paper (MFW) means paper specially manufactured so that its tensile strength, water resistance, smoothness, etc. are enhanced compared to general paper. For example, the basis weight of the fifth wrapper 245 is 57 g / m 2 ~63 g / m 2 It may be included within the range, and preferably may be 60 g / m 2 It may be. Also, the thickness of the fifth wrapper 245 may be included within the range of 64 μm to 70 μm, and preferably may be 67 μm.

[0061] A predetermined substance may 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 without oxidation, resistance to various chemicals, water repellency to water, or electrical insulation. However, even if it is not silicon, any substance having the above-described properties can be applied (or coated) to the fifth wrapper 245 without limitation.

[0062] The fifth wrapper 245 can prevent the phenomenon of the wrapped tobacco 2 from burning. Generally, when the tobacco rod 210 is heated by the heater 13, the wrapped tobacco 2 may burn. For example, when the temperature rises above the ignition point of any of the substances contained in the tobacco rod 310, the wrapped tobacco 2 can burn. In one embodiment, since the fifth wrapper 245 contains a non-combustible substance, in this case, the wrapped tobacco 2 can be prevented from burning.

[0063] In addition, the fifth wrapper 245 can prevent the holder 1 from being contaminated by the substances generated by the wrapped tobacco 2. Depending on the user's puff, a liquid substance can be generated inside the wrapped tobacco 2. For example, when the aerosol generated by the wrapped tobacco 2 is cooled by the external air, a liquid substance (such as moisture, etc.) can be generated. In this case, wrapping the wrapped tobacco 2 with the fifth wrapper 245 can prevent the liquid substance generated inside the wrapped tobacco 2 from leaking outside the wrapped tobacco 2.

[0064] The tobacco rod 21 contains aerosol product substances. For example, the aerosol product substances can 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. In addition, 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 can be added to the tobacco rod 21 by spraying it onto the tobacco rod 21.

[0065] The tobacco rod 21 can be manufactured in various ways. For example, the tobacco rod 21 may be made of a sheet or a strand. Also, the tobacco rod 21 may be made of cut tobacco in which the tobacco sheet is finely cut. Further, the tobacco rod 21 can be surrounded by a heat-conductive material. For example, the heat-conductive material may be a metal foil such as aluminum foil, but is not limited thereto. As an example, the heat-conductive material surrounding the tobacco rod 21 can evenly disperse the heat transmitted to the tobacco rod 21 and improve the heat conductivity applied to the tobacco rod, thereby improving the tobacco flavor. Also, the heat-conductive material surrounding the tobacco rod 21 can function as a susceptor heated by an induction heater. At this time, although not shown in the drawings, the tobacco rod 21 can include an additional susceptor in addition to the heat-conductive material surrounding the outside.

[0066] The filter rod 22 can be a cellulose acetate 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 rod or a tube-type rod including a hollow inside. Also, the filter rod 22 may 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.

[0067] The first segment of the filter rod 22 can be a cellulose acetate filter. For example, the first segment can be a tubular structure including a hollow inside. When the heater 13 is inserted by the first segment, it is also possible to prevent the phenomenon that the internal substance of the tobacco rod 210 is pushed backward, and a cooling effect of the aerosol can also be generated. The diameter of the hollow included in the first segment may adopt an appropriate diameter within the range of 2 mm to 4.5 mm, but is not limited thereto.

[0068] 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 may be 10 mm, but is not limited thereto.

[0069] The hardness of the first segment can be adjusted by adjusting the content of the plasticizer during the production of the first segment. Further, the first segment can be manufactured by inserting a structure such as a film or a tube made of the same or different materials inside (for example, hollow).

[0070] 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 to an appropriate temperature.

[0071] The length or diameter of the second segment can be determined variously depending on the form of the wrapped tobacco 2. For example, the length of the second segment can be appropriately adopted within the range of 7 mm to 20 mm. Preferably, the length of the second segment may be about 14 mm, but is not limited thereto.

[0072] The second segment can be made by weaving polymer fibers. In this case, a flavoring liquid can also be applied to the fibers made of the polymer. Alternatively, the second segment can be made by weaving together fibers made of a polymer and separately provided fibers coated with a flavoring liquid. Alternatively, the second segment can be formed by a wound polymer sheet.

[0073] For example, the polymer can 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.

[0074] By being formed of woven polymer fibers or wound polymer sheets, the second segment can include one or more channels extending in the longitudinal direction. Here, a channel means a passage through which a gas (e.g., air or aerosol) passes.

[0075] For example, the second segment made of a wound polymer sheet can be formed of a material having a thickness between about 5 μm and about 300 μm, such as between about 10 μm and about 250 μm. Also, the total surface area of the second segment can be between about 300 mm 2 and about 1000 mm 2 Furthermore, the aerosol cooling element can be formed of a material having a specific surface area between about 10 mm 2 / mg and about 100 mm 2 / mg.

[0076] On the other hand, the second segment can 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 can be filled with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0077] The third segment of the filter rod 22 can be a cellulose acetate filter. The length of the third segment may be appropriately adopted within the range of 4 mm to 20 mm. For example, the length of the third segment may be about 12 mm, but is not limited thereto.

[0078] In the process of manufacturing the third segment, it can also be manufactured so that a fragrance is generated by injecting a flavoring liquid into the third segment. Alternatively, a separate fiber coated with the flavoring liquid can also 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 via the third segment. Therefore, when a flavoring element is added to the third segment, it is possible to produce an effect of enhancing the persistence of the fragrance transmitted to the user.

[0079] Furthermore, the filter rod 22 may contain at least one capsule 23. Here, the capsule 23 can also perform a function of generating a fragrance and can also perform 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 can have a spherical or cylindrical shape, but is not limited thereto.

[0080] Referring to FIG. 5, the wrapped tobacco 3 can further include a shear plug 33. The shear plug 33 can be located on one side of the tobacco rod 31 facing the filter rod 32. The shear plug 33 can prevent the tobacco rod 31 from detaching externally and can prevent the aerosol liquefied from the tobacco rod 31 from flowing into the aerosol generating device (FIGS. 1 to 3) during smoking.

[0081] The filter rod 32 can include a first segment 321 and a second segment 322. Here, the first segment 321 corresponds to the first segment of the filter rod 22 in FIG. 4, and the second segment 322 corresponds to the third segment of the filter rod 22 in FIG. 4.

[0082] The diameter and total length of the wrapped cigarette 3 correspond to those of the wrapped cigarette 2 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.

[0083] The wrapped cigarette 3 can be wrapped by at least one wrapper 35. At least one hole can be formed in the wrapper 35 for external air to flow in or internal gas to flow out. For example, the shear plug 33 can be wrapped by the first wrapper 351, the tobacco rod 31 can be wrapped by the second wrapper 352, the first segment 321 can be wrapped by the third wrapper 353, and the second segment 322 can be wrapped by the fourth wrapper 354. Also, the whole wrapped cigarette 3 can be re-wrapped by the fifth wrapper 355.

[0084] Also, at least one perforation 36 can be formed in the fifth wrapper 355. For example, the perforation 36 can be formed in the region surrounding the tobacco rod 31, but it is not limited thereto. The perforation 36 can serve to transfer the heat generated by the heater 13 shown in FIGS. 2 and 3 to the inside of the tobacco rod 31.

[0085] Furthermore, the second segment 322 may contain at least one capsule 34. Here, the capsule 34 can 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 can have a spherical or cylindrical shape, but it is not limited thereto.

[0086] The first wrapper 351 may be one in which a metal foil such as aluminum foil is bonded to a general filter paper. For example, the total thickness of the first wrapper 351 may be within the range of 45 μm to 55 μm, and preferably may be 50.3 μm.

Also, when the aerosol generator 400 generates aerosol by an induction heating method, the aerosol generator 400 further includes a DC / AC converter that converts the DC power source of the battery 440 into an AC power source.

[0112] 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 perform functions when power is supplied from the battery 440.

[0121] The control unit 410 can control the overall operation of the aerosol generator 400. In one embodiment, the control unit 410 includes at least one processor. The processor may be implemented as an array of multiple logic gates, or may 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 can understand that it can be implemented in further forms of hardware.

[0122] 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 the switching element between the battery 440 and the heater 450. In a different example, according to the control command of the control unit 410, the direct heating circuit may control the power supply to the heater 450.

[0123] The control unit 410 analyzes the results detected by the detection unit 420 and 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 disclosed or terminated based on the results detected by the detection unit 420. As another 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.

[0124] The control unit 410 controls the output unit 430 based on the results detected by the detection unit 420. For example, when the number of puffs counted via the puff sensor 426 reaches a preset number, the control unit 410 notifies the user that the aerosol generator 400 will end immediately via at least one of the display unit 432, the haptic unit 434, and the acoustic output unit 436.

[0125] 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 an over-wet state, the control unit 410 controls the power supply time to the induction coil and can increase the preheating time compared to when the aerosol-generating article is in a general state.

[0126] One embodiment can also be realized in the form of a recording medium including computer-executable instruction words such as program modules executed by a computer.
