[0048] A cigarette may comprise a tobacco rod and a filter rod.

[0049] Tobacco rods may be formed from pieces, shreds and small fragments cut from tobacco sheets.

[0050] Additionally, the tobacco rod may be surrounded by a heat conductive material.

[0051] For example, the thermally conductive material may be, but is not limited to, a metal foil, such as aluminum foil.

[0052] The filter rod may comprise a cellulose acetate filter portion.

[0053] The filter rod may comprise at least one segment.

[0054] For example, a filter rod may include a first section configured to cool the aerosol and a second section configured to filter specific components in the aerosol.

[0055] In another embodiment, the aerosol generating device may be a device that generates an aerosol by using a cartridge containing an aerosol generating substance.

[0056] The aerosol generating device may include a cartridge and a main body, wherein the cartridge contains the aerosol generating substance and the main body supports the cartridge.

[0057] The cigarette cartridge may be detachably coupled to the main body, but is not limited thereto.

[0058] The cartridge may be formed integrally with the main body or may be assembled with the main body, and the cartridge may also be fixed to the main body without being detached from the main body by the user.

[0059] The cartridge may be mounted on the main body while the aerosol-generating substance is contained in the cartridge.

[0060] However, the present disclosure is not limited thereto. The aerosol generating substance may also be injected into the cartridge when the cartridge is coupled to the body.

[0061] The cartridge can contain the aerosol-generating substance in any of various states, such as liquid, solid, gas, gel, etc.

[0062] The aerosol-forming substance may comprise a liquid composition.

[0063] For example, the liquid composition can be a liquid comprising a tobacco-containing material having a volatile tobacco flavoring component, or the liquid composition can be a liquid comprising a non-tobacco material.

[0064] The cartridge may be operated by an electrical signal or a wireless signal transmitted from the main body to perform a function of generating an aerosol by converting the phase of the aerosol-generating substance inside the cartridge into a gas phase.

[0065] Aerosol can refer to a gas formed by a mixture of vaporized particles generated by an aerosol-generating substance and air.

[0066] In another embodiment, the aerosol generating device may generate an aerosol by heating a liquid composition, and the generated aerosol may be delivered to the user via a cigarette.

[0076] The induction heating method may be a method of generating heat from a magnetic substance by applying an alternating magnetic field.

[0077] When an alternating magnetic field is applied to a magnetic substance, energy may be lost in the magnetic substance due to eddy currents and hysteresis losses.

[0078] The lost energy may be dissipated from the magnetic material as heat.

[0079] The greater the amplitude or frequency of the alternating magnetic field applied to the magnetic substance, the more heat energy can be dissipated from the magnetic substance.

[0080] An induction heating aerosol generating device may comprise a susceptor and a coil.

[0081] As an example, the susceptor may be disposed outside of and adjacent to the dielectric member.

[0082] As another example, the susceptor may be positioned within the dielectric member.

[0084] In one embodiment, the susceptor may include a magnetic material that generates heat when an external magnetic field is applied.

[0085] As another example, the susceptor may comprise a non-magnetic metal.

[0090] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0091] Figure 1 is a schematic cross-sectional view of an aerosol generating device 1 including an aerosol generator 10 and a main body 20 according to an embodiment.

[0092] Reference Figure 1 The aerosol generating device 1 according to the embodiment may include an aerosol generator 10 and a main body 20 .

[0093] The aerosol generator 10 may be detachably coupled to the main body 20. The aerosol generator 10 may be referred to as a cartridge.

[0094] The aerosol generator 10 may include a storage portion 11 , a transmission portion 12 , and a generation portion 13 .

[0095] The aerosol generating substance may be stored in the storage portion 11. The aerosol generating substance stored in the storage portion 11 may be provided to the transmission portion 12 included in the aerosol generator 10.

[0096] The transport portion 12 may filter out foreign matter in the aerosol-generating substance. For example, the transport portion 12 may perform a function of filtering out foreign matter having a specific size or larger from the aerosol-generating substance.

[0097] In addition, the delivery portion 12 may perform the function of adding a substance to the aerosol-generating substance. For example, the delivery portion 12 may add a flavoring substance to the aerosol-generating substance.

[0098] The transport portion 12 can perform the dual functions of filtering out a substance from the aerosol-generating substance and adding a substance to the aerosol-generating substance. That is, the transport portion 12 can perform at least one of the function of filtering out a substance from the aerosol-generating substance and the function of adding a substance to the aerosol-generating substance.

[0099] The transmission part 12 may be disposed between the storage part 11 and the generation part 13 .

[0100] For example, the transmission portion 12 may be disposed inside the storage portion 11 and may be in contact with the generation portion 13. In another example, a fluid channel for the flow of the aerosol-generating substance may be formed between the storage portion 11 and the generation portion 13, and the transmission portion 12 may be disposed in the fluid channel between the storage portion 11 and the generation portion 13.

[0101] The transmission portion 12 may include a sealing portion (not shown). The sealing portion may be used to prevent the aerosol-generating substance stored in the storage portion 11 from leaking outside the aerosol generator 10 or from leaking into the main body 20. The sealing portion may be located between the storage portion 11 and the transmission portion 12. For example, the sealing portion may be coupled to the storage portion 11 by a force-fit method, but is not limited thereto. The sealing portion may include an elastic material, such as rubber.

[0102] The sealing portion may be located between the storage portion 11 and the transmission portion 12. The sealing portion may be disposed at an edge of the transmission portion 12. The sealing portion may be formed integrally with the transmission portion 12.

[0103] In another example, the sealing portion may be located between the transmitting portion 12 and the generating portion 13 .

[0104] The generating part 13 may receive the aerosol generating substance from the transmitting part 12. The generating part 13 may generate aerosol from the aerosol generating substance.

[0105] In the present disclosure, “aerosol” may refer to vapor obtained by aerosolizing an aerosol-generating substance.

[0106] The generating portion 13 may include a heater and a wick. The aerosol generating substance transferred to the generating portion 13 may be absorbed into the wick and heated by the heater.

[0107] The heater may heat the aerosol-generating substance absorbed by the core. The heater may be wound around the core. For example, the heater may heat the aerosol-generating substance absorbed into the core by utilizing power supplied from a battery of the main body 20.

[0108] The heater may include a metal material that generates heat through electrical resistance. For example, the heater may include stainless steel to prevent corrosion caused by aerosol-generating substances absorbed by the wick, but the metal material of the heater is not limited thereto. In another example, the heater may include a metal material such as copper, nickel, or tungsten.

[0109] The wick may be located inside the generating portion 13 to absorb the aerosol generating substance stored in the storage portion 11 .

[0110] According to one embodiment, the core may include a cotton material. However, the material of the core is not limited to the above embodiment, and according to an embodiment, the core may also include other materials (eg, glass or ceramic).

[0111] In another example, the generating portion 13 may include a vibrator. The vibrator may generate aerosol from the aerosol generating substance by using an ultrasonic vibration method. The generating portion 13 may generate aerosol by atomizing the aerosol generating substance using ultrasonic vibration generated by the vibrator.

[0112] The generating portion 13 may generate short-period vibrations using a vibrator to atomize the aerosol generating substance. The vibrations generated by the vibrator may be ultrasonic vibrations, and the frequency bandwidth of the ultrasonic vibrations may be about 100 kHz to about 3.5 MHz, but the present disclosure is not limited thereto.

[0113] The generating portion 13 may further include a core. For example, the core may surround at least one region of the vibrator, or the core may be in contact with at least one region of the vibrator.

[0114] When a voltage (e.g., AC voltage) is applied to the vibrator, heat and / or ultrasonic vibrations may be generated by the vibrator, and the heat and / or ultrasonic vibrations generated by the vibrator may be transmitted to the aerosol-generating substance absorbed into the core. The aerosol-generating substance absorbed into the core may be changed into a gas phase by the heat and / or ultrasonic vibrations transmitted from the vibrator, thereby generating an aerosol.

[0115] For example, the viscosity of the aerosol-generating substance absorbed into the core may be reduced by heat generated by the vibrator, and the aerosol-generating substance having the reduced viscosity due to ultrasonic vibration generated by the vibrator may be changed into fine particles, thereby generating aerosol, but the present disclosure is not limited thereto.

[0116] The aerosol generator 10 may include an opening 14. The aerosol generated by the aerosol generating substance may be discharged to the outside through the opening 14. The generating portion 13 may communicate with the outside through the opening 14. The user may inhale the aerosol generated by the generating portion 13 through the opening 14.

[0117] The aerosol generator 10 may be detachably coupled to the main body 20. The main body 20 may support the aerosol generator 10. Components for operating the aerosol generating device 1 may be located inside the main body 20.

[0118] It will be understood by those skilled in the art that the aerosol generating device 1 may further include, in addition to Figure 2 Other components than those shown in FIG.

[0119] In the following, reference is made to Figure 2 The coupling relationship between the aerosol generator 10 and the main body 20 is described in detail.

[0120] Figure 2 It shows Figure 1 2 is a cross-sectional view of a state in which the aerosol generator 10 and the main body 20 of the aerosol generating device 1 shown in FIG.

[0121] Reference Figure 2 According to one embodiment, an aerosol generating device 1 may include an aerosol generator 10 and a main body 20. The components of the aerosol generating device 1 may be Figure 1 The components of the aerosol generating device 1 shown in FIG are the same or similar, and therefore, in the following, references previously made to Figure 1 A description of the components is given and omitted from the following description.

[0122] The main body 20 may include a coupling portion 21 , an air inlet 22 , an air flow channel 23 , a controller 24 , and a battery 25 .

[0123] The aerosol generator 10 may be detachably coupled to the coupling portion 21. The coupling portion 21 may include a component for detachably coupling the aerosol generator 10 to the coupling portion 21. The aerosol generator 10 may include a component for detachably coupling to the coupling portion 21 at a position corresponding to the coupling portion 21. The aerosol generator 10 may be coupled to the main body 20 by being coupled to the coupling portion 21, and may be detached from the main body 20 by being detached from the coupling portion 21.

[0124] When the aerosol generator 10 is coupled to the body 20 , the generating portion 13 of the aerosol generator 10 may be located on at least a portion of the coupling portion 21 .

[0125] An air inlet 22 may be formed in the body 20 to introduce external air into the aerosol generating device 1. For example, the air inlet 22 may be formed on one side of the body 20, such as Figure 2 , the air inlet 22 may be formed at various positions to introduce external air into the aerosol generating device 1 .

[0126] In another example, with Figure 2 Unlike the structure shown in , the air inlet 22 may be formed in the aerosol generator 10. In this case, an air flow channel described later may also be formed in the aerosol generator 10.

[0127] An area of ​​the airflow channel 23 may be formed in the space between the main body 20 and the aerosol generator 10. The airflow channel 23 may form a flow path through which external air introduced through the air inlet 22 flows into the interior of the aerosol generating device 1. The airflow channel 23 may be arranged between the air inlet 22 and the generating portion 13 so that the air inlet 22 communicates with the generating portion 13. That is, air introduced into the aerosol generating device 1 through the air inlet 22 may reach the generating portion 13 along the airflow channel 23.

[0128] When the pressure in the space where the generating portion 13 is arranged decreases due to the user's inhalation action through the opening 14, the external air introduced through the air inlet 22 of the main body 20 can move to the generating portion 13 via the air flow channel 23. The aerosol aerosolized by the aerosol-generating substance through the generating portion 13 can be mixed with the air introduced through the air flow channel 23 and discharged to the outside through the opening 14.

[0129] Through the above configuration, the aerosol generating device 1 can transmit the aerosol generated by the aerosol generator 10 to the outside.

[0130] Figure 2It is shown that the controller 24 and the battery 15 are arranged in a row inside the main body 20. In addition, the internal structure of the main body 20 is not limited to Figure 2 In other words, the arrangement of the coupling portion 21 , the air inlet 22 , the air flow channel 23 , the controller 24 and the battery 25 may be changed according to the design of the main body 20 .

[0131] The controller 24 generally controls the operation of the aerosol generating device 1. Specifically, the controller 24 controls the operation of the aerosol generator 10, the battery 15, and other components included in the aerosol generating device 1. In addition, the controller 24 can check the status of the components of the aerosol generating device 1 and determine whether the aerosol generating device 1 is in an operable state.

[0132] The controller 24 includes one or more processors. The processor may include an array of multiple logic gates, or may include a combination of a general-purpose microprocessor and a memory storing programs that can be executed by the general-purpose microprocessor. In addition, those skilled in the art of the present embodiment will understand that the processor may include other types of hardware.

[0133] The battery 25 supplies power for operating the aerosol generating device 1. For example, the battery 25 can supply power to the generating portion 13 so that the generating portion 13 can generate aerosol, and can also supply power required for operating the controller 24.

[0134] The aerosol generating device 1 may also include other components. For example, the aerosol generating device 1 may include a display capable of displaying visual information and / or a motor capable of outputting tactile information. Furthermore, the aerosol generating device 1 may include a puff detection sensor, a temperature detection sensor, a cigarette insertion detection sensor, and the like. Furthermore, the aerosol generating device 1 may have a structure that allows external air to be introduced into the aerosol generating device 1 or allows internal gas to be exhausted.

[0135] The battery 25 can supply power required to operate a display, a sensor, a motor, and the like installed in the aerosol generating device 1 .

[0136] Figure 3 It shows Figure 1 and Figure 2 sectional view of the aerosol generator 10.

[0137] Reference Figure 3 According to one embodiment, the aerosol generator 10 may include a storage portion 11, a transmission portion 12, a generation portion 13, and an opening 14. The components of the aerosol generator 10 may be Figure 1 and Figure 2The components of the aerosol generator 10 shown in FIG. 1 are the same or similar, and are hereinafter referred to as previously referred to. Figure 1 and Figure 2 A description of the components is given and omitted from the following description.

[0138] The aerosol-generating substance stored in the storage portion 11 of the aerosol generator 10 may include a tobacco-containing substance containing volatile tobacco flavoring components, or may include a liquid composition containing a non-tobacco substance.

[0139] According to one embodiment, the liquid composition may include any one of water, solvent, ethanol, plant extract, flavoring substance and vitamin mixture, or a mixture thereof. The flavoring substance may include, but is not limited to, menthol, mint, spearmint oil, and various fruit flavoring ingredients. The flavoring substance may include ingredients that can provide a variety of flavors or tastes 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. The liquid composition may also include an aerosol former, such as glycerol and propylene glycol.

[0140] For example, the liquid composition may include a solution of glycerol and propylene glycol at a certain weight ratio to which a nicotine salt is added. The liquid composition may also include two or more nicotine salts. The nicotine salt may be formed by adding a suitable acid, including an organic acid or an inorganic acid, to nicotine. The nicotine may be naturally occurring nicotine or synthetic nicotine and may have a certain suitable weight concentration relative to the total solution weight of the liquid composition.

[0141] The acid used to form the nicotine salt can be appropriately selected by considering the rate of nicotine absorption in the blood, the operating temperature of the aerosol generating device, flavor or taste, solubility, etc. For example, the acid used to form the nicotine salt can be a single acid selected from the group consisting of benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid, or malic acid, or a mixture of two or more acids selected from the group consisting of, but not limited to, benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid, or malic acid.

[0142] The aerosol-generating substance stored in the storage portion 11 may move in one direction toward the generating portion 13. In this case, the transfer portion 12 may be located between the storage portion 11 and the generating portion 13. The transfer portion 12 may change at least some of the components of the aerosol-generating substance in the storage portion 11 before the aerosol-generating substance is transferred to the generating portion 13.

[0143] For example, the transmission portion 12 may be a porous material portion having a specific size or smaller and may prevent foreign matter contained in the aerosol generating substance from being transmitted to the generating portion 13 by filtering foreign matter having a specific size or larger from the aerosol generating substance.

[0144] The transmission portion 12 is a porous material portion having a specific size or smaller and filters foreign matter having a specific size or larger from the aerosol generating substance, and therefore, high-quality aerosol generated from the aerosol generating substance can be provided to the user.

[0145] In another example, the delivery portion 12 may include an additive substance that may alter the properties of the aerosol-generating substance, and may add the additive substance to the aerosol-generating substance.

[0146] For example, the transmission section 12 may include a flavoring substance, and the transmission section 12 may provide flavor to the aerosol-generating substance by adding the flavoring substance to the aerosol-generating substance. During the process of the transmission section 12 transmitting the aerosol-generating substance to the generating section 13, the flavoring substance contained in the transmission section 12 may mix with the aerosol-generating substance, dissolve in the aerosol-generating substance, or react with the aerosol-generating substance, thereby providing flavor to the aerosol-generating substance.

[0147] In another example, the transmission portion 12 may include a viscous substance that adjusts the viscosity of the aerosol-generating substance. The transmission portion 12 may perform the function of changing the viscosity of the aerosol-generating substance by adding the viscous substance to the aerosol-generating substance.

[0148] In another example, the delivery portion 12 may include an acidity control substance that controls the acidity of the liquid (the pH, which indicates the presence of hydrogen ions and is a measure of acidity or alkalinity). The delivery portion 12 may change the acidity of the aerosol-generating substance by adding an acidic substance to the aerosol-generating substance.

[0149] In another example, the transmission portion 120 may include various substances that may be included in the above-mentioned aerosol-generating substances (e.g., tobacco-containing substances, non-tobacco substances, plant extracts, vitamin mixtures, aerosol formers, nicotine, mixtures thereof, etc.), and may perform the function of changing the properties of the aerosol-generating substances.

[0150] By including the transfer portion 12 , the aerosol generator 10 can change the properties of the aerosol-generating material before it is aerosolized without interrupting the transfer of the aerosol-generating material from the storage portion 11 to the generating portion 13 .

[0151] The transport section 12 may perform the functions of the transport section 12 in a complex manner. For example, the transport section 12 may filter out foreign matter having a specific size or larger from the aerosol-generating substance while adding a flavoring substance to the aerosol-generating substance.

[0152] The delivery portion 12 may include a flavoring substance and add the flavoring substance to the aerosol-generating substance. Thus, an aerosol-generating substance that does not have a flavor can be flavored by the delivery portion 12. That is, when the aerosol generator 10 includes the delivery portion 12, it is not necessary to pre-add the flavoring to the aerosol-generating substance, and the flavoring can be added immediately before providing the aerosol to the user.

[0153] When various additive substances that may be included in the aerosol-forming substance are dissolved in the aerosol-forming substance or mixed with the aerosol-forming substance, the flash point and / or fire point of the aerosol-forming substance may be reduced. However, when the flash point and / or fire point of the aerosol-forming substance is lower than or equal to a certain temperature, the transportation cost of the aerosol-forming substance may increase. For example, a region may require explosion-proof design, such as installing partitions, separate packaging, in order to transport liquids with a flash point and / or fire point lower than or equal to a certain temperature on an aircraft. In this case, there may be a risk of excessively increasing the cost of transporting aerosol-forming substances due to the explosion-proof design, thereby significantly reducing the profitability of the aerosol generator 10 or significantly increasing the cost of providing the aerosol generator 10 to the user.

[0154] According to an embodiment, a certain substance that can lower the flash point and / or ignition point of the aerosol-generating substance when dissolved in the aerosol-generating substance is included in the transmission portion 12 handled separately from the storage portion 11, rather than being dissolved in or mixed with the aerosol-generating substance stored in the storage portion 11. Therefore, the flash point and / or ignition point of the aerosol-generating substance can be increased to a certain temperature or higher, and the transportation cost of the aerosol-generating substance can be reduced, thereby improving the profitability of the aerosol generator 10.

[0155] As another example, by varying the thickness of the transmission portion 12, the rate at which the aerosol-forming substance is transmitted to the generation portion 13 can be adjusted, and the concentration of the aerosol-forming substance in the aerosol can be adjusted. For example, when the transmission portion 12 is relatively thick, the rate at which the aerosol-forming substance is transmitted to the generation portion 13 can be reduced compared to when the transmission portion 12 is relatively thin, and the user can achieve a lower concentration of the aerosol-forming substance under the same conditions. Manufacturers can distribute transmission portions 12 having various thicknesses, and users can select a transmission portion 12 having a thickness that achieves a desired aerosol substance concentration.

[0156] Figures 4 to 8 Reference is shown Figures 1 to 3 A schematic diagram of a detailed embodiment of the transmission part 12 is described.

[0157] Figure 4 and Figure 5 is a view showing the transmission portion 12 having a carbon structure.

[0158] The transfer portion 12 may have a carbon structure including activated carbon that prevents foreign matter contained in the aerosol-generating substance from being transferred to the generating portion 13 by filtering foreign matter having a specific size or larger from the aerosol-generating substance.

[0159] The carbon structure may include a material containing carbon and may be used to remove foreign matter. Specifically, the carbon structure may be activated carbon. Activated carbon is a porous material, such as charcoal, the main component of which is carbon, and has a large surface area and strong adsorption properties. Activated carbon may be formed from wood, coconut, or coal that has undergone a special heat treatment. Activated carbon is a porous material containing countless micropores, and when aerosol-forming substances pass through the activated carbon, foreign matter in the aerosol-forming substances can be filtered out.

[0160] Reference Figure 4 , the carbon structure included in the transmission portion 12 may include a plurality of granular activated carbons 121 a.

[0161] Granules refer to small particles having the size of sand, and the plurality of granular activated carbons 121a are granules of activated carbon. At least some of the plurality of granular activated carbons 121a may be formed into a columnar shape, a rod shape, or the like.

[0162] Furthermore, when the aerosol-generating substance passes through the transport section 12, it passes through the plurality of granular activated carbons 121a along the shortest and easiest path among the paths within the plurality of granular activated carbons 121a. Due to this property, a passage portion for the aerosol-generating substance to pass through is formed within the transport section 12, and the aerosol-generating substance that passes through the transport section 12 rarely comes into contact with the entire transport section 12.

[0163] For example, the path can be greatly reduced by appropriately designing the channel portion inside the plurality of granular activated carbons 121 a , and the amount of aerosol passing through the transmission portion 12 can be adjusted by lengthening or shortening the channel portion.

[0164] In another example, flavoring may be added near the channel portion formed inside the plurality of granular activated carbons 121a so that the additive substance is effectively added to the aerosol-generating substance. The plurality of granular activated carbons 121a may each be formed in a rod shape.

[0165] Reference Figure 5 The carbon structure of the transmission portion 12 may include a plurality of carbon blocks 121b made of a solid material containing carbon. Each of the plurality of carbon blocks 121b may be formed by aggregating carbon powder. The carbon powder may be formed by decomposing activated carbon.

[0166] The aerosol-generating substance may pass through the dense carbon powder constituting each of the plurality of carbon blocks 121 b, and during this process, foreign matter in the aerosol-generating substance may be adsorbed to each of the plurality of carbon blocks 121 b. When the carbon powder is coated with an additive such as a flavoring substance, the plurality of carbon blocks 121 b may also provide flavor to the aerosol-generating substance.

[0167] Reference Figure 6 , the transmission portion 12 may include a mesh structure 122 that is porous and prevents foreign matter contained in the aerosol generating substance from being transmitted to the generating portion 13 by filtering foreign matter having a specific size or larger from the aerosol generating substance.

[0168] The reticular structure 122 may include capillary fibers. The reticular structure 122 may be formed by welding a pad of capillary fibers. The reticular structure 122 may be formed by weaving or non-woven materials. The fibers formed by weaving or non-woven materials may be parallel to each other, twisted, or tangled, or may be any one or all of these types of fibers. The reticular structure 122 may include a single material or multiple materials. The material may be metal, non-metal, natural material, or synthetic material, or may be a natural material and a synthetic material. For example, the fibers of the reticular structure 122 may be formed by cellulose fibers or stainless steel.

[0169] Since the porous mesh structure 122 does not allow foreign matter having a certain size or larger to pass therethrough, foreign matter having a certain size or larger contained in the aerosol-generating substance passing through the transmission portion 12 can be removed.

[0170] Reference Figure 7 The transmission portion 12 may include a fiber structure 123 formed of a porous fiber material, which prevents foreign matter contained in the aerosol generating substance from being transmitted to the generating portion 13 by filtering foreign matter having a specific size or larger from the aerosol generating substance.

[0171] For example, the fiber structure 123 may be a cotton structure formed of a cotton material. The porous fiber structure 123 is not limited to a cotton structure and may include various fiber materials that allow fluid to pass through, such as cotton.

[0172] Since the porous fiber structure 123 does not allow foreign matter having a certain size or larger to pass therethrough, foreign matter having a certain size or larger contained in the aerosol-generating substance passing through the transmission portion 12 can be removed.

[0173] Reference Figure 8 , the transmitting portion 12 may include a ceramic structure 124 that is porous and prevents foreign matter contained in the aerosol generating substance from being transmitted to the generating portion 13 by filtering foreign matter having a specific size or larger from the aerosol generating substance.

[0174] The ceramic structure 124 is formed by firing porous ceramic powder at a high temperature, and can remove foreign matter through its fine pores (pores with a diameter of 0.5 μm to 1 μm). Since the porous ceramic structure 124 does not allow foreign matter of a certain size or larger to pass through, foreign matter of a certain size or larger contained in the aerosol-forming substance passing through the transmission section 12 can be removed.

[0175] Reference Figures 4 to 8 The described embodiments of the transmission part 12 can be used individually or in combination.

[0176] Figure 9 An enlarged view of an example where an additive substance is added to the transfer portion 12 is shown. Figure 9 An enlarged portion of the transmission section 12 is shown.

[0177] The transmission portion 12 may include a plurality of grains (particles), and the plurality of grains may be coated with an additive substance.

[0178] Figure 9 (a) shows an example of crystal grains forming the structure included in the transmission portion 12 . Figure 9 The grains shown in (a) are not coated with additive material. Therefore, additive material is not added to the grains that only include Figure 9 (a) The transmission portion 12 of the particles is an aerosol-forming substance.

[0179] Figure 9 (b) shows an example of a state in which particles forming the structure included in the transport portion 12 are coated with an additive substance. Figure 9 Examples of the coating substance of the particles in (b) may include the above-mentioned flavoring substances, sticky substances, acidity control substances, nicotine, vitamins, and aerosol formers.

[0180] The aerosol-generating substance stored in the storage section 11 can be moved to the generating section 13 by passing through the transmitting section 12, and when the aerosol-generating substance passes through the transmitting section 12, the additive substance applied to the particles in (b) can be dissolved in the aerosol-generating substance or mixed with the aerosol-generating substance to be added to the aerosol-generating substance.

[0181] After a certain volume or more of the aerosol-forming substance passes through the delivery portion 12, the additive substance may be removed from the particles, and the particles may have the same or similar morphology as shown in (a). In this case, all the additive substance is used up in the delivery portion 12. Therefore, the user can replace the delivery portion and / or aerosol generator with another delivery portion and / or aerosol generator.

[0182] Figure 10 It shows Figure 3 sectional view of the aerosol generator 10 in a disassembled configuration.

[0183] Reference Figure 10 According to one embodiment, the aerosol generator 10 may include an aerosol storage portion 11, a transmission portion 12, a generation portion 13, and an opening 14. The components of the aerosol generator 10 may be Figure 3 The components of the aerosol generator 10 shown in FIG. 1 are the same or similar, and are hereinafter referred to as previously referred to. Figure 3 A description of the components is given and omitted from the following description.

[0184] At least one of the storage portion 11 , the transmission portion 12 , and the generation portion 13 included in the aerosol generator 10 may be detachably coupled to the other components.

[0185] For example, the transmission portion 12 may be detachably coupled to at least one of the storage portion 11 and the generation portion 13 .

[0186] The transmission part 12 can continuously perform the function of filtering out foreign matter, even when a certain amount of aerosol generating material stored in the storage part 11 is completely consumed after passing through the transmission part 12 and the generating part 13, the transmission part 12 can continuously perform the function of filtering out foreign matter.

[0187] In another example, even when a certain amount of aerosol-generating substance stored in the storage portion 11 is completely consumed after passing through the transmission portion 12 and the generation portion 13, the transmission portion 12 may still contain the additive substance. In other words, the transmission portion 12 can still perform the function of adding the additive substance to the aerosol-generating substance.

[0188] In such a case, replacing the aerosol generator 10 including the delivery portion 12 due to depleted aerosol-generating material may be a waste of resources.

[0189] In addition, even when the aerosol generating substance in the storage portion 11 is completely consumed, the generating portion 13 can still perform the function of generating aerosol.

[0190] When at least one of the storage portion 11 , the transmission portion 12 , and the generation portion 13 included in the aerosol generator 10 is detachable from other components, these components can be selectively and individually replaced, thereby preventing waste of resources.

[0191] For example, if the delivery portion 12 is detachable from the aerosol generator 10 , then when the aerosol-generating substance in the reservoir 11 is depleted, the user may replace other components without having to replace the delivery portion 12 .

[0192] In contrast, when the additive substance in the delivery portion 12 is exhausted, the user may replace only the delivery portion 12 without having to replace other components of the aerosol generator 10 .

[0193] To this end, the manufacturer of the aerosol generator 10 may manufacture and distribute the aerosol generator 10 without the transmission portion 12 , and may manufacture and distribute the transmission portion 12 separately.

[0194] Generally speaking, when a manufacturer wants to change the properties of an aerosol-generating substance, the manufacturer must change a production line for the aerosol-generating substance or build new production equipment, which requires a lot of cost.

[0195] When the transmission portion 12 is made detachable from the aerosol generator 10, the user can change the properties of the aerosol-generating substance by replacing only the transmission portion 12. For example, by replacing a previously used transmission portion with another transmission portion that includes another additive substance, the user can change various properties of the aerosol-generating substance, such as the flavor type, flavor concentration, atomization amount, or nicotine concentration of the aerosol.

[0196] In addition, when the transmission portion 12 is separated from the aerosol generator 10, the aerosol-generating substance in the storage portion 11 may leak to the outside. To prevent this, a blocking portion (not shown) may be formed between the storage portion 11 and the transmission portion 12 to prevent the transmission of the fluid. The blocking portion may include a blocking plate or a blocking valve structure. The blocking portion may be movable between a blocking position and an open position.

[0197] For example, the blocking portion may be moved between the blocking position and the open position by a separate operation of the user. In this case, the user may move the blocking portion to the blocking position by performing a separate operation and then separate the transmission portion 12 from the aerosol generator 10. The user may then couple the transmission portion 12 to the aerosol generator 10 and then move the blocking portion to the open position by performing a separate operation.

[0198] For example, the blocking portion may automatically move to the blocking position when the transmission portion 12 is separated from the aerosol generator 10 , and may automatically move to the open position when the transmission portion 12 is coupled to the aerosol generator 10 .

[0199] According to an embodiment of the present disclosure, the manufacturer can change the performance of the aerosol generating substance provided to the user by only changing the additive substance of the transmission part 12, and therefore, compared with the method that requires completely redesigning the aerosol generator 10, the same purpose can be achieved with lower manufacturing equipment costs, the manufacturing cost of the aerosol generator 10 can be reduced, and the aerosol generator 10 can be provided to the user at a more economical price.

[0200] In another example, when the reservoir 11 is detachable from the aerosol generator 10 , the user may continue to use the transmission portion 12 and the generation portion 13 and only replace the reservoir 11 .

[0201] In another example, when the generating portion 13 is detachable from the aerosol generator 10 , the user may continuously use the storage portion 11 and the transmission portion 12 and replace only the generating portion 13 .

[0202] In addition, as described above, the aerosol generating device 1 may include a component that can output information to the outside, such as a display, and the aerosol generating device 1 may include a component that can control other components, such as a controller.

[0203] The controller of the main body 20 may calculate whether the replacement period of the transmission part 12 has expired.

[0204] For example, when the aerosol generating device 1 is used for a certain period of time after the transmission portion 12 is first coupled to the aerosol generator 10 , the controller may determine that a replacement period for the transmission portion 12 has expired.

[0205] In another example, the controller may determine that a replacement period for the transmission portion 12 has expired when a particular number of puffs has been detected by a puff sensor of the aerosol generating device 10 after the transmission portion 12 is first coupled to the aerosol generator 10 .

[0206] In another example, in an embodiment where the reservoir 11 is detachable and replaceable, the controller may determine that the replacement period of the transmission portion 12 has expired upon detecting that the reservoir 11 has been replaced a certain number of times after the transmission portion 12 is first coupled to the aerosol generator 10 .

[0207] When the replacement period of the transmission part 12 expires, the controller may output information about replacing the transmission part to the outside. For example, when the replacement period of the transmission part 12 expires, the aerosol generating device 1 may display a text message on the display indicating that the transmission part 12 needs to be replaced.

[0208] In another example, the controller may include a speaker, and when the replacement period of the transmission part 12 expires, the controller may output a voice message to the speaker indicating that the transmission part 12 needs to be replaced.

[0209] In another example, the controller may include a vibration motor, and when a replacement period of the transmission portion 12 expires, the controller may cause the vibration motor to vibrate to notify the user through tactile sensation that the transmission portion 12 needs to be replaced.

[0210] Figure 11 is a schematic cross-sectional view of an aerosol generating device 1 including an aerosol generator 10 , a main body 20 and a dielectric member 30 according to one embodiment.

[0211] Reference Figure 11 According to one embodiment, the aerosol generating device 1 may include an aerosol generator 10, a main body 20 and a medium member 30. The components of the aerosol generating device 1 may be Figure 1 and Figure 2 The components of the aerosol generating device 1 shown in FIG. 1 are the same or similar and are referred to hereinafter as previously with reference to FIG. Figure 1 and Figure 2 A description of the components is given and omitted from the following description.

[0212] According to one embodiment, the medium member 30 (e.g., a cigarette) may be housed in the aerosol generator 10. The aerosol generator 10 may include a housing portion for housing the medium member 30, and the aerosol generated inside the aerosol generator 10 may be discharged to the outside of the aerosol generating device 1 by passing through the medium member 30 housed in the housing portion. In this case, the user may contact the medium member 30 through his mouth and inhale the aerosol through the medium member 30. Figure 12 and Figure 13 A detailed description of the dielectric member 30 according to one embodiment will be described.

[0213] Figure 12 and Figure 131 is a view showing an example of a dielectric member according to another embodiment. Figure 12 and Figure 13 An example of the dielectric member is described.

[0214] Reference Figure 12 , the medium member 3 includes a tobacco rod 31 and a filter rod 32. The first portion of the medium member 3 includes the tobacco rod 31, and the second portion of the medium member 3 includes the filter rod 32.

[0215] Figure 12 While the filter rod 32 is shown as comprising a single segment, the filter rod 32 is not limited thereto. In other words, the filter rod 32 may comprise multiple segments. For example, the filter rod 32 may comprise a first segment that cools the aerosol and a second segment that filters predetermined components contained in the aerosol. Furthermore, the filter rod 32 may further comprise at least one segment that performs other functions, as desired.

[0216] The diameter of the media member 3 is in the range of 5 mm to 9 mm, and the length of the media member 3 may be approximately 48 mm, but is not limited thereto. For example, the length of the media member 3 may be approximately 12 mm, the length of the first section of the filter rod 32 may be approximately 10 mm, the length of the second section of the filter rod 32 may be approximately 14 mm, and the length of the third section of the filter rod 32 may be approximately 12 mm, but is not limited thereto.

[0217] The dielectric member 3 can be packaged by at least one packaging member 34. The packaging member 34 can have at least one hole through which external air can be introduced or internal air can be exhausted. For example, the dielectric member 3 can be packaged by one packaging member 34. In another example, the dielectric member 3 can be packaged by two or more packaging members 34 in an overlapping manner. For example, the tobacco rod 31 can be packaged by a first packaging member 341, and the filter rod 32 can be packaged by packaging members 342, 343, and 344. In addition, the dielectric member 3 can be completely repackaged by a single packaging member 34. When the filter rod 320 includes a plurality of segments, each segment can be packaged by packaging members 342, 343, and 344.

[0218] The first packaging member 341 and the second packaging member 342 can be made of common filter wrapping paper. For example, the first packaging member 341 and the second packaging member 342 can be porous wrapping paper or non-porous wrapping paper. In addition, the first packaging member 341 and the second packaging member 342 can be made of oil-resistant paper sheets and / or aluminum-laminated packaging materials.

[0219] The third packaging member 343 can be made of hard packaging paper. For example, the basis weight of the third packaging member 343 can be 88g / m 2 Up to 96g / m 2In the range of , preferably, the basis weight of the third package 343 can be 90g / m 2 Up to 94g / m 2 In addition, the thickness of the third package member 343 may be in the range of 120 μm to 130 μm. Preferably, the thickness of the third package member 343 may be 125 μm.

[0220] The fourth packaging member 344 can be made of oil-resistant hard packaging paper. For example, the basis weight of the fourth packaging member 344 can be about 88g / m 2 About 96g / m 2 In the range of, preferably, the basis weight of the fourth package 344 can be 90g / m 2 Up to 94g / m 2 In addition, the thickness of the fourth package member 344 may be in the range of 120 μm to 130 μm. Preferably, the thickness of the fourth package member 344 may be 125 μm.

[0221] The fifth packaging member 345 may be made of sterile paper (MFW). Here, sterile paper (MFW) refers to paper that is specially made to have enhanced tensile strength, water resistance, smoothness, etc. compared to ordinary paper. For example, the basis weight of the fifth packaging member 345 may be 57 g / m 2 Up to 63g / m 2 In the range of, preferably, the basis weight of the fifth package 345 can be 60g / m 2 In addition, the thickness of the fifth package member 345 may be in the range of 64 μm to 70 μm, and preferably, the thickness of the fifth package member 345 may be 67 μm.

[0222] A predetermined material may be added to the interior of the fifth packaging member 345. Examples of the predetermined material include, but are not limited to, silicon. For example, silicon has properties such as heat resistance that varies little with temperature, oxidation resistance that does not oxidize, resistance to various chemicals, water resistance, or electrical insulation. However, any material other than silicon having the aforementioned properties may be applied (or coated) to the fifth packaging member 345 without limitation.

[0223] The fifth packing member 345 can prevent the medium member 3 from burning. In particular, when the temperature rises above the ignition point of any of the materials contained in the tobacco rod 31, the medium member 3 may burn. Even in this case, the medium member 3 can be prevented from burning because the fifth packing member 345 includes a non-combustible material.

[0224] Furthermore, the fifth packaging member 345 prevents contamination of the aerosol generating device 1 by substances generated by the dielectric member 3. Liquid substances may be generated within the dielectric member 3 through inhalation by the user. For example, when the aerosol generated within the dielectric member 3 is cooled by external air, liquid substances (e.g., moisture) may be generated. Because the fifth packaging member 345 packages the dielectric member 3, it prevents liquid substances generated within the dielectric member 3 from leaking outside the dielectric member 3.

[0225] The tobacco rod 31 may include an aerosol-generating substance. For example, the aerosol-generating substance may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. Furthermore, the tobacco rod 31 may include other additives, such as flavoring agents, humectants, and / or organic acids. Furthermore, the tobacco rod 31 may include a flavoring liquid, such as menthol or a humectant, injected into the tobacco rod 31.

[0226] The tobacco rod 31 can be manufactured in various forms. For example, the tobacco rod 31 can be formed into a sheet or shreds. Alternatively, the tobacco rod 31 can be formed into shredded tobacco formed from tiny pieces cut from a tobacco sheet. Furthermore, the tobacco rod 31 can be surrounded by a heat-conductive material. For example, the heat-conductive material can be a metal foil such as aluminum foil, but is not limited thereto. For example, the heat-conductive material surrounding the tobacco rod 31 can evenly distribute the heat transferred to the tobacco rod 31, thereby increasing the thermal conductivity applied to the tobacco rod and improving the flavor of the tobacco.

[0227] The filter rod 32 may include a cellulose acetate filter portion. The shape of the filter rod 32 is not limited. For example, the filter rod 32 may include a cylindrical rod, or may be a tubular rod with a hollow portion therein. Furthermore, the filter rod 32 may include a concave rod. When the filter rod 32 includes multiple segments, at least one of the multiple segments may have a different shape.

[0228] The first section of the filter rod 32 may be a cellulose acetate filter. For example, the first section may be a tubular structure including a hollow portion. The diameter of the hollow portion in the first section may be appropriately within the range of 2 mm to 4.5 mm, but is not limited thereto.

[0229] The length of the first segment can be appropriately adopted in the range of 4mm to 30mm, but is not limited thereto. Preferably, the length of the first segment can be 10mm, but is not limited thereto.

[0230] The hardness of the first segment can be adjusted by adjusting the content of the plasticizer during the preparation of the first segment. In addition, the first segment can be manufactured by inserting a structure such as a film or a tube made of the same or different material into the interior (e.g., the hollow portion) of the first segment.

[0231] The length or diameter of the second segment can be determined in various ways according to the shape of the dielectric member 3. For example, the length of the second segment can be appropriately adopted in the range of 7 mm to 20 mm. Preferably, the length of the second segment is about 14 mm, but is not limited thereto.

[0232] The second segment can be made by weaving polymer fibers. In this case, the flavoring liquid can be applied to the polymer fibers. Alternatively, the second segment can be made by weaving together separate fibers coated with the flavoring liquid and the polymer fibers. Alternatively, the second segment can be made from a rolled polymer sheet.

[0233] For example, the polymer may be made of a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil.

[0234] Since the second section is made of woven polymer fibers or curled polymer sheets, the second section may include one or more passages extending in the longitudinal direction. Here, a passage may refer to a channel for gas (eg, air or aerosol) to pass through.

[0235] For example, the second segment formed from the rolled polymer sheet can be formed from a material having a thickness between about 5 μm and about 300 μm. For example, the second segment formed from the rolled polymer sheet can be formed from a material having a thickness between about 10 μm and about 250 μm. In addition, the total surface area of ​​the second segment can be between about 300 mm 2 / mm and about 1000mm 2 In addition, the aerosol-cooling element may be formed of a material having a thickness between about 10 mm and about 10 mm. 2 / mg and about 100mm 2 Materials with a specific surface area between 100 and 100 mg are formed.

[0236] Furthermore, the second segment may include a thread containing a volatile flavoring component. Here, the volatile flavoring component may be, but is not limited to, menthol. For example, the thread may include a sufficient amount of menthol to provide at least 1.5 mg of menthol to the second segment.

[0237] The third section of the filter rod 32 may be a cellulose acetate filter. The length of the third section may be appropriately selected within the range of 4 mm to 20 mm. For example, the length of the third section may be approximately 12 mm, but is not limited thereto.

[0238] During the manufacturing process of the third segment, flavor can be generated by spraying a flavoring liquid onto the third segment. Alternatively, separate fibers coated with a flavoring liquid can be inserted into the third segment. The aerosol generated in the tobacco rod 41 can be cooled as it passes through the second segment of the filter rod 32, and the cooled aerosol can then pass through the third segment and be delivered to the user. Therefore, when a flavoring element is added to the third segment, the longevity of the flavor delivered to the user can be enhanced.

[0239] Furthermore, the filter rod 32 may include at least one capsule 33. The capsule 33 may also generate flavor or aerosol. For example, the capsule 33 may be configured to encapsulate a liquid containing a flavoring substance with a membrane. For example, the capsule 33 may be spherical or cylindrical, but is not limited thereto.
