[0002] Recently, there has been an increasing demand for alternative methods to overcome the drawbacks of conventional cigarettes. For example, there is a growing need for methods that generate aerosols by heating aerosol-generating substances within an aerosol-generating article containing a medium (rather than generating aerosols by burning cigarettes).

Figure 3 This is a block diagram of an aerosol generating apparatus according to an embodiment of the present disclosure.

[0027] Reference Figures 1 to 3 According to the disclosed embodiments, the aerosol generating apparatus 101 may include a housing 150, a first heater 125, a second heater 126, a color determination unit CS1, and a battery 129.

[0028] The outer casing 150 can be shaped and can be configured in various forms such as a rod shape or a box shape. Inside the outer casing 150, a battery 129, a control unit 121, a first heater 125, a second heater 126, etc., can be arranged. The outer casing 150 can have a receiving space 151 for inserting the aerosol generating article 130, and the receiving space 151 can be located at the top of the outer casing 150. The outer casing 150 may also be provided with a cover for opening and closing the receiving space 151.

[0029] The aerosol generating apparatus 101 may also include an aerosol generating article 130. For example... Figure 3 As shown, the aerosol generating article 130 can be configured as a cylindrical rod, but the present invention is not limited thereto. The aerosol generating article 130 may include one or a combination of two or more substances in various states such as liquid, solid, and gel that are capable of generating aerosols.

[0030] The aerosol generating article 130 may include a medium section 132, a first segment 131, a second segment 133, a third segment 134, and a wrapping member TR1. However, this is exemplary, and the aerosol generating article 130 may be configured in various forms; the present invention is not limited to the structure of the aerosol generating article 130.

[0031] The medium section 132 may include at least one component selected from granular tobacco (tobacco pellets), reconstituted tobacco, and shredded tobacco. Furthermore, the medium section 132 may also include an aerosol-generating substance such as glycerin. Additionally, the medium section 132 may contain other additives such as flavoring agents, humectants, and / or organic acids. Furthermore, flavoring liquids such as menthol or humectants may be added to the medium section 132 by spraying it onto the medium section 132.

[0032] In one embodiment, the first segment 131 can be constructed using a cellulose acetate filter. Furthermore, the first segment 131 can be constructed using a paper filter and a porous molded material, etc. For example, the length of the first segment 131 can be 4 to 15 mm, but is not limited thereto. Furthermore, the first segment 131 can include glycerol, menthol, flavoring substances, etc., to produce atomization. Furthermore, the first segment 131 can have a specific shape such as a Y-shape or an X-shape, and can be configured as a circular filament bundle shape, etc.

[0033] The second segment 133 and the third segment 134 can be constructed using a cellulose acetate filter. Furthermore, at least one flavor capsule may be included in either the second segment 133 or the third segment 134. Alternatively, the second segment 133 and the third segment 134 can be constructed using a cellulose acetate filter mixed with a flavoring agent. As one example, the second segment 133 or the third segment 134 can be constructed using a hollow filter; as another example, the third segment 134 may be omitted.

[0034] The wrapping component TR1 may include a first roll of paper 137, a second roll of paper 138, a third roll of paper 139, a first colored section 135, a second colored section 136, and an outer cover TR2. At least one hole may be formed in the wrapping component TR1 for the inflow of external air or the outflow of internal gas. The wrapping component TR1 may be made of a material with high thermal conductivity.

[0035] The media section 132 can be packaged with the first roll of paper 137, the second section 133 can be packaged with the second roll of paper 138, and the third section 134 can be packaged with the third roll of paper 139. Furthermore, the first section 131 can be packaged with the first color section 135, and a portion of the second section 133 can be packaged with the second color section 136.

[0036] The aerosol-generating article 130 can be repackaged with an outer shell TR2, and the outer shell TR2 can be made using sterile paper (MFW), but this disclosure is not limited thereto.

[0037] The first color portion 135 may be located at the front end of the aerosol generating article 130, and may be located further forward than the medium portion 132. The first color portion 135 may be located between the first segment 131 and the outer skin TR2, or may be arranged on the outside of the outer skin TR2.

[0038] When the first color portion 135 is located inside the outer skin TR2, the portion of the outer skin TR2 surrounding the first color portion 135 can be constructed using a light-transmitting layer. The light-transmitting layer can transmit 10% to 90% of the light. The light-transmitting layer can be a single layer or multiple layers; specifically, it can be multiple layers.

[0039] The light-transmitting layer may include one or more materials selected from the group consisting of polyolefins, agar, and cellulose. When the light-transmitting layer includes all of the polyolefin, agar, and cellulose materials, the layer becomes more transparent and exhibits superior temperature stability.

[0040] The light-transmitting layer may include a first layer containing a polyolefin, a second layer containing agar, and a third layer containing a cellulosic material. For example, the first to third layers may be stacked on top of each other to form a stacked film. Specifically, the polyolefin may be one selected from the group consisting of polyethylene, polypropylene, and combinations thereof, and the cellulosic material may be α-cellulose, β-cellulose, or hydroxyalkyl cellulose.

[0041] The first color portion 135 may include metal, and as an example, may include a metal film and paper. The metal film may include pure aluminum (Al) or an aluminum alloy, specifically, it may include pure aluminum.

[0042] The purity of pure aluminum can be above 98% or above 99%. In addition to aluminum, aluminum alloys can also include one or more metals selected from the group consisting of copper (Cu), manganese (Mn), silicon (Si), magnesium (Mg), and zinc (Zn).

[0043] In this case, the aluminum content, based on the total weight of the aluminum alloy, can be 50% or more by weight, 60% or more by weight, 70% or more by weight, 80% or more by weight, or 90% or more by weight.

[0044] like Figure 4 As shown, an anodized film 160 can be formed in the first color section 135. The anodized film 160 can have various colors, such as red, green, blue, yellow, purple, etc.

[0045] The anodic oxide film 160 can be formed by anodizing. Here, anodizing refers to attaching a metal to an anode and electrolyzing it in an electrolyte, thereby forming an oxide film with adhesion to the metal by using the oxygen generated at the anode.

[0046] The anodized thin film 160 may include a porous layer 161 formed on a metal thin film substrate SB1 and a sealing layer 162 formed on the porous layer 161. The sealing layer 162 may be formed by various methods such as organic sealing treatment. The substrate SB1 may be made of a metal thin film such as aluminum.

[0047] Multiple fine pores 163 caused by oxidation can be formed in the porous layer 161. The sealing layer 162 can be formed by coating or impregnating with organic materials such as synthetic resins. The first color portion 135 can have various colors by means of the sealing layer 162 described above.

[0048] The sealing layer 162 basically includes a color display substance, and in addition to the color display substance, may also include one or more of a conductive polymer, a fragrance enhancer, and a fragrance enhancer anti-shedding agent. The pores 163 may include a first pore and a second pore, and the types of functional materials carried in the first pore and the types of functional materials carried in the second pore may be the same or different from each other.

[0049] The sealing layer 162 may contain a conductive polymer, thereby effectively preventing the decrease in conductivity caused by the presence of the anodic oxide film 160.

[0050] The conductive polymer is not particularly limited, and may include polymers with a conductivity of 1 S / cm or more, 10 S / cm or more, or 100 S / cm or more at 20°C. Specifically, it may include polymers with a conductivity ranging from 1 S / cm to 1000 S / cm. Specifically, the conductive polymer may include one or more polymers selected from the group consisting of polyacetylene, poly(p-phenylene), poly(p-phenylene sulfonate), polythiophene, poly(p-phenyleneethylene), poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT-PSS), and polyaniline.

[0051] The weight-average molecular weight (Mw) of the conductive polymer is not particularly limited, but can specifically be from 1,000 g / mol to 500,000 g / mol, from 1,000 g / mol to 100,000 g / mol, or from 1,000 g / mol to 10,000 g / mol. According to several embodiments, when the weight-average molecular weight of the conductive polymer meets the above-mentioned numerical range, the conductive polymer can better penetrate into the voids.

[0052] The sealing layer 162 may include flavoring substances. Specifically, flavoring substances are included inside the pores 163, thereby providing consumers with a variety of satisfactions and even a smoking experience. When the aerosol generating article is inserted into the aerosol generating device, the flavoring substances contained in the aerosol generating article roll are atomized and applied to the consumer's mouth. Flavoring substances are not particularly limited, but may include menthol, natural plant flavorings, sugars, cocoa compounds, esters, etc.

[0053] Furthermore, the second color portion 136 is arranged separately from the first color portion 135 across the medium portion 132, and may be located outside the second segment 133. The second color portion 136 may be configured such that a color display material is colored onto the outer skin TR2. As another example, the second color portion 136 may also include an aluminum film with an anodized film formed thereon.

[0054] Color-displaying substances are not particularly limited and can be materials that alter the color of rolls of aerosol-generating articles. Specifically, the color-displaying substance can be one selected from the group consisting of dyes, pigments, and mixtures thereof.

[0055] In several examples, the dye is not particularly limited and can be a dye commonly used in the art. Specifically, the dye can be a disodium salt of ethyl[4-[p[ethyl(msulfobenzyl)amino]-α-(o-sulfophenyl)benzylidene]-2,5-cyclohexadien-1-ylidene](m-sulfobenzyl)ammonium hydroxide inner salt and a disodium salt of 6-hydroxy-5-[(2-methyl-4-sulfophenyl)azo]-2-naphthalenesulfonic acid or a mixture thereof.

[0056] In several examples, the pigment is not particularly limited and may be selected from the group consisting of organic pigments, inorganic pigments, and mixtures thereof. In several other examples, the pigment may include a thermochromic pigment whose color changes with temperature.

[0057] In several examples, the pigment may include one or more of bis(dimethylammonium)tetrachloronickelate, bis(diethylammonium)tetrachlorocuprate, vanadium dioxide, and nickel sulfate.

[0058] In addition, a first heater 125, a second heater 126, a color judgment unit CS1, an inductive recognition unit 123, a battery 129, and a control unit 121 may be provided inside the housing 150, and a display unit 141, an input unit 128, a lamp 142, etc. may be provided outside the housing.

[0059] The display unit 141 can display the remaining battery level, heating mode, device status, etc. The lamp 142 can be composed of LEDs or the like, and can use color to indicate the heating status, etc.

[0060] The input unit 128 can receive information input by the user, such as a keypad, dome switch, touchpad, jog wheel, jog switch, etc., but is not limited to these. The user can use the input unit 128 to manually set the heating mode.

[0061] The aerosol generating apparatus 101 may include a first heater 125 and a second heater 126, which may be located outside the aerosol generating article 130 to heat the aerosol generating article 130. The first heater 125 and the second heater 126 may be configured as hollow tubes or as curved surfaces facing the outer peripheral surface of the aerosol generating article 130 and surrounding the aerosol generating article.

[0062] For example, the first heater 125 and the second heater 126 may be resistance heaters. For example, the first heater 125 and the second heater 126 may include conductive tracks, which can be heated as current flows through them.

[0063] As another example, the first heater 125 and the second heater 126 may also include an induction coil and a heating element heated by the induction coil. Specifically, the first heater 125 and the second heater 126 may generate heat by a magnetic field produced by an alternating current flowing through the induction coil.

[0064] like Figure 1 As shown, the first heater 125 and the second heater 126 can be configured to surround the outer peripheral surface of the aerosol generating article 130 to heat the outer peripheral surface of the aerosol generating article 130, and the first heater 125 and the second heater 126 can be formed to heat different parts of the aerosol generating article 130 and have the same length.

[0065] As another example, such as Figure 5 As shown, the first heater 125 and the second heater 126 can be arranged adjacent to the outer peripheral surface of the aerosol generating article 130, and the lengths (the portions extending along the length direction of the aerosol generating article) of the first heater 125 and the second heater 126 can be different.

[0066] The first length L1 of the first heater 125 extending along the length direction of the aerosol generating article 130 can be formed to be greater than the second length L2 of the second heater 126 extending along the length direction of the aerosol generating article 130. Here, the first length L1 can be configured to be 1.2 to 3 times the second length L2. If the first length L1 is formed to be greater than the second length L2, the first heater 125 becomes the main heater and can heat up rapidly, while the second heater 126, as an auxiliary heater, can precisely control the temperature of the aerosol generating article 130.

[0067] As another example, such as Figure 6 As shown, the first heater 125 can be constructed using a heating rod inserted inside the aerosol generating article 130, and the second heater 126 can be configured to heat the outer peripheral surface of the aerosol generating article 130. If the first heater 125 is inserted inside the aerosol generating article 130 and the second heater 126 is configured to surround the outer peripheral surface of the aerosol generating article, not only can the aerosol generating article 130 be heated rapidly, but the temperature regulation of the aerosol generating article 130 is also easier.

[0068] Battery 129 can supply power for the operation of aerosol generating device 101. For example, battery 129 can supply current to first heater 125, second heater 126, control unit 121, and various sensors.

[0069] Inside the outer casing 150, a cartridge may be disposed, which may contain an aerosol-forming substance in one of the following states: liquid, solid, gaseous, or gel.

[0070] For example, the liquid composition can be a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it can be a liquid containing non-tobacco substances.

[0071] For example, the cartridge can be integrally formed with the housing or detachably attached to the housing. The cartridge can be connected to the receiving space 151 through a channel.

[0072] As another example, a moisture sensor can be installed inside the housing 150. The moisture sensor can measure the humidity of the aerosol-generating article 130. The location of the moisture sensor is not particularly limited and can be located inside the aerosol generating device 101 to measure the humidity of the aerosol-generating article 130.

[0073] Moisture sensors are not particularly limited and can be any device for measuring moisture. Specifically, a moisture sensor can be a moisture measuring device that utilizes near-infrared spectroscopy, wherein, in near-infrared spectroscopy, moisture is measured by ensuring that the emitted light beam is obtained after irradiating the aerosol generating article 130 with near-infrared wavelengths that have a high affinity for moisture.

[0074] The inductance recognition unit 123 recognizes the change in inductance caused by the insertion of the aerosol-generating article 130 and transmits the signal to the control unit 121. For example... Figure 1 As shown, the inductive recognition unit can be arranged to be spaced downward from the front end of the aerosol generating article 130 and to face the front end of the aerosol generating article 130.

[0075] When the aerosol generating article 130 is inserted into the aerosol generating apparatus 101, the magnitude and direction of the magnetic field or current change due to the presence of the first color part 135 containing metal and the conductive polymer, and an induced electromotive force can be generated. Inductance refers to the ratio of magnetic flux to current. The inductance can be determined according to the type of conductive polymer, thereby determining the operating conditions of the aerosol generating article 130.

[0076] As another example, such as Figure 5 As shown, the inductive recognition unit 123 can also be arranged to face the outer peripheral surface of the first color unit 135. The inductive recognition unit 123 and the first color sensor 122 can be separated by the aerosol generating article 130. As another example, the first color sensor 122 can be fixed to the inductive recognition unit 123 or formed integrally with the inductive recognition unit 123.

[0077] If the aerosol generating article 130 is inserted, an inductance change occurs through the first color part 135 containing metal, and the inductance recognition unit 123 recognizes the inductance change and transmits it to the control unit 121.

[0078] If a signal is transmitted from the inductor recognition unit 123, the control unit 121 determines that the aerosol generating article 130 has been inserted and the power is turned on, and can control the color judgment unit CS1 to measure the color.

[0079] The color determination unit CS1 may include a first color sensor 122 and a second color sensor 124. However, the present invention is not limited thereto, and the color determination unit CS1 may also include only one color sensor.

[0080] The first color sensor 122 senses the color of the first color unit 135 and measures the RGB value of the first color unit 135 to determine whether the color of the first color unit 135 corresponds to one of the preset colors.

[0081] The second color sensor 124 senses the color of the second color unit 136 and measures the RGB value of the second color unit 136 to determine whether the color of the second color unit 136 corresponds to one of the preset colors.

[0082] The memory 127 can store preset heating modes, and can store multiple heating modes that match the information transmitted from the first color sensor 122 and the second color sensor 124. The heating modes may include the heating modes of the first heater 125 and the second heater 126.

[0083] In this disclosure, the control unit 121 controls the operation of the aerosol generating apparatus 101 as a whole. Specifically, the control unit 121 controls not only the battery 129, the first heater 125, the second heater 126, and the inductive recognition unit 123, but also the operation of other components included in the aerosol generating apparatus 101.

[0084] Based on the information transmitted from the first color sensor 122 and the second color sensor 124, the control unit 121 retrieves the heating mode according to the specified color from the heating modes stored in the memory 127, and controls the first heater 125 and the second heater 126 using the corresponding heating mode.

[0085] Based on information transmitted from the first color sensor 122, the control unit 121 controls the initial heating temperature of the first heater 125 and the second heater 126 during a preset initial heating time, and controls the reheating temperature of the first heater 125 and the second heater 126 during a preset reheating time based on information transmitted from the second color sensor 124. Here, the initial heating time can be 30 to 50 seconds, and the reheating time can be 15 to 25 seconds after the initial heating time.

[0086] As another example, based on information transmitted from the first color sensor 122, the control unit 121 can heat the first heater 125 or the second heater 126 within a preset initial heating temperature range. After a preset number of reheating and suction cycles, the control unit 121 can then heat the first heater 125 or the second heater 126 within a preset reheating temperature range. Here, the number of reheating and suction cycles can be 5 to 9. For this purpose, a suction sensor can be provided inside the housing 150.

[0087] As another example, the control unit 121 can heat the first heater 125 at an initial heating temperature range based on information transmitted from the first color sensor 122, and can heat the first heater 125 and the second heater 126 at a reheating temperature range after a first heating and suction cycle based on information transmitted from the second color sensor 124.

[0088] As another example, based on the information transmitted from the first color sensor 122, the control unit 121 can heat the first heater 125 and the second heater 126 within the initial heating temperature range, interrupt the heating after a number of reheating suction cycles, and based on the information transmitted from the second color sensor 124, can heat only the first heater 125 within the reheating temperature range.

[0089] As another example, the control unit 121 can also control the heating of the first heater 125 based on the information transmitted from the first color sensor 122, and can control the heating of the second heater 126 based on the information transmitted from the second color sensor 124.

[0090] Specifically, when the first color sensor 122 senses a first color, the control unit 121 can heat the first heater 125 and the second heater 126 within a first temperature range. When the first color sensor 122 senses a second color, the control unit 121 can heat the first heater 125 and the second heater 126 within a second temperature range lower than the first temperature range. Furthermore, when the first color sensor 122 senses a third color, the control unit 121 can heat the first heater 125 and the second heater 126 within a third temperature range lower than the second temperature range.

[0091] Here, the first color can be red, the second color can be blue, and the third color can be green, but this disclosure is not limited to these, and the colors can be set in various ways. Furthermore, when the first color sensor 122 senses white, the first heater 125 and the second heater 126 can be heated at the highest temperature.

[0092] The first temperature range can be 190 to 220 degrees Celsius, the second temperature range can be 160 to 190 degrees Celsius, and the third temperature range can be 130 to 160 degrees Celsius. The maximum temperature can be above 170 degrees Celsius.

[0093] As another example, the control unit 121 can heat the first heater 125 and the second heater 126 during a preset initial heating time, cool the first heater 125 and the second heater 126 during a cooling time, and interrupt heating after heating at a temperature 60 to 80 degrees Celsius lower than the maximum temperature. Here, the initial heating time can be 30 to 50 seconds, and the cooling time can be 15 to 25 seconds.

[0094] As another example, when the second color sensor 124 senses the first color, the control unit 121 can heat the first heater 125 only at the first reheating temperature after a preset number of suctions; when the second color is sensed, the control unit 121 can heat the first heater 125 only at the second reheating temperature; and when the third color is sensed, the control unit 121 can interrupt the heating of the first heater 125.

[0095] Here, the first reheating temperature can be between 180 and 200 degrees Celsius, and the second reheating temperature can be between 150 and 170 degrees Celsius. The control unit 121 reheats the first heater 125 only for the reheating time, which can be between 25 and 35 seconds.

[0096] In addition, when the user manually changes the heating mode, the control unit 121 can control the first heater 125 and the second heater 126 according to the heating mode specified by the user.

[0097] As described above, according to this disclosure, various combinations of heating modes can be achieved using the first color sensor 122 and the second color sensor 124, and optimal taste can be provided to the user. Furthermore, the aerosol-generating article 130 is heated to a precise heating temperature based on the heating time using the first heater 125 and the second heater 126, thereby minimizing the difference between the initial and subsequent aerosols.

[0098] The following describes an aerosol generation method according to an embodiment of the present disclosure.

[0099] Figure 7 This is a flowchart illustrating an aerosol generation method according to an embodiment of the present disclosure. The aerosol generation method can be achieved through… Figures 1 to 6 The aerosol generating device described herein is used to perform this action. Figures 1 to 6 The aerosol generation device described herein can also be applied to... Figure 7 Methods for generating aerosols.

[0100] The aerosol generation method according to this embodiment may include a step S101 of sensing an inductance change caused by the insertion of the aerosol generating article 130. The step S101 of sensing the inductance change identifies the inductance change caused by the insertion of the aerosol generating article 130 and transmits a signal to a control unit. In the step S101 of sensing the inductance change, when the aerosol generating article is inserted, the inductance change caused by the first color portion 135 made of metal is sensed.

[0101] The aerosol generation method according to this embodiment may include a color sensing step S102, which uses a color determination unit CS1 to sense the color of a portion of the aerosol generating article. In the color sensing step S102, two color sensors 122 and 124 may be used to determine the colors of different locations on the aerosol generating article. For example, in the color sensing step S102, the first color sensor 122 may be used to determine the color of a first color portion 135 located at the front end of the aerosol generating article 130, and the second color sensor 124 may be used to determine the color of a second color portion 136 separated from the first color portion 135 by a medium portion 132. In the color sensing step S102, it may be determined whether the sensed color corresponds to one of the colors stored in the memory 127 and a match may be made.

[0102] The aerosol generation method according to this embodiment may further include a step S103 of setting a heating mode of the heater based on information transmitted from the color determination unit CS1. In the step S103 of setting the heating mode, a heating mode stored in the memory 127 is retrieved based on information transmitted from the color sensing step S102, and a matching heating mode is set.

[0103] In step S103 of setting the heating mode, a consistent heating mode can be set using two color information transmitted from the first color sensor 122 and the second color sensor 124.

[0104] As an example, in step S103 of setting the heating mode, the initial heating temperature of the first heater 125 and the second heater 126 can be controlled based on the information transmitted from the first color sensor 122, and the reheating temperature of the first heater 125 or the second heater 126 can be set based on the information transmitted from the second color sensor 124.

[0105] As another example, in step S103 of setting the heating mode, the heating temperature and time of the first heater 125 can be set based on the information transmitted from the first color sensor 122, and the heating temperature and time of the second heater 126 can be set based on the information transmitted from the second color sensor 124.

[0106] The aerosol generation method according to this embodiment may further include a step S104 of heating the aerosol generating article in a set heating mode. In step S104 of heating the aerosol generating article 130, the aerosol generating article 130 may be heated using a first heater 125 and a second heater 126, and the first heater 125 and the second heater 126 may be controlled with different temperatures and different heating times.

[0107] In step S104, the first heater 125 and the second heater 126 can be heated within a preset initial heating temperature range. After a preset number of reheating and suction cycles, the first heater 125 or the second heater 126 can be heated within a preset reheating temperature range. Here, the number of reheating and suction cycles can reach 5 to 9 times.

[0108] As an example, in step S104 of heating the aerosol-generating article, the first heater 125 and the second heater 126 can be heated within the initial heating temperature range, and heating can be interrupted after a number of reheating suction cycles, with only the first heater 125 heated within the reheating temperature range.

[0109] As another example, in step S104 of heating the aerosol-generating article, only the first heater 125 can be heated within the initial heating temperature range, and after a number of reheating and suction cycles, both the first heater 125 and the second heater 126 can be heated within the reheating temperature range.

[0110] Furthermore, in step S104, which involves heating the aerosol-generating article, the first heater 125 and the second heater 126 can be heated during a pre-set initial heating time, and can be cooled during a cooling time, with heating interrupted after reaching a temperature 60 to 80 degrees Celsius lower than the maximum temperature. Here, the initial heating time can be 30 to 50 seconds, and the cooling time can be 15 to 25 seconds.
