Abstract

The pouch for the aerosol generating device includes a liquid composition that generates an aerosol when heated, and a water-soluble film that encases the liquid composition.

Description

[Technical Field]

[0001] The present invention relates to a pouch, a vaporizer including said pouch, and an aerosol generating device including said pouch. [Background technology]

[0002] Recently, there has been an increasing demand for alternative methods that overcome the shortcomings of conventional cigarettes. For example, rather than generating aerosols by burning cigarettes, there has been an increasing demand for systems that generate aerosols by heating cigarettes or aerosol-generating substances using an aerosol generator. This has led to active research into heated aerosol generators.

[0003] The aerosol generating device for generating an aerosol by heating a liquid composition includes a vaporizer having the liquid composition, the vaporizer being integrally formed with the body of the aerosol generating device or being detachably connected thereto. Summary of the Invention [Problem to be solved by the invention]

[0004] Vaporizers are generally made of a material that has sealing power to prevent leakage of the liquid composition and heat resistance to withstand the heat generated when heating the liquid composition. However, disposable vaporizers that are detachably connected to aerosol generating devices are discarded when all of the liquid composition initially stored therein is consumed, so economical manufacturing and disposal of the vaporizer is required.

[0005] The problems to be solved through the embodiments are not limited to the problems mentioned above, and problems not mentioned will be clearly understood by a person having ordinary skill in the art to which the embodiments pertain from this specification and the attached drawings. [Means for solving the problem]

[0006] The pouch according to one embodiment includes a liquid composition that generates an aerosol when heated, and a water-soluble film surrounding the liquid composition.

[0007] Another embodiment of the vaporizer includes a liquid composition that generates an aerosol when heated, a pouch including a water-soluble film that encases the liquid composition, and a heating unit that is detachably connected to the pouch and heats the liquid composition.

[0008] In yet another embodiment, the aerosol generating device comprises a main body configured to accommodate an aerosol product, a pouch including a water-soluble film that encases a liquid composition that generates an aerosol when heated, and a vaporizer that is detachably connected to the pouch and includes a heating section that heats the liquid composition, wherein the main body and the vaporizer are detachably connected, and the aerosol generated by the vaporizer passes through the aerosol product.

[0009] The means for solving the problem are not limited to those described above, but include any matter that can be inferred by a person skilled in the art throughout this specification. [Effects of the Invention]

[0010] In the pouch according to the embodiment and the vaporizer including the same, when the liquid composition is consumed, only the pouch is replaced with a new pouch, and the other components can be used continuously. Because the pouch includes a water-soluble film, the used pouch can be easily and economically disposed of by simply exposing it to water. In addition, the water-soluble film of the pouch is lightweight and relatively flexible in shape, making it easy to replace and allowing it to contain a relatively large amount of liquid composition.

[0011] The effects of the embodiment are not limited to those described above, and may include any effects that can be inferred from the configurations described below. [Brief explanation of the drawings]

[0034] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand the present invention. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0036] 1 and 2 are diagrams showing an example in which an aerosol product is inserted into an aerosol generating device.

[0037] 1 and 2, the aerosol generating device 100 includes a battery 110, a control unit 120, a heater 130, and a vaporizer 140. An aerosol product 200 is inserted into the internal space of the aerosol generating device 100.

[0038] 1 and 2 includes a vaporizer, the embodiment is not limited by the implementation method of the aerosol generation device, and the vaporizer may be omitted from the aerosol generation device 100. When the vaporizer is omitted from the aerosol generation device 100, the aerosol production product 200 contains an aerosol-generating substance, and when the aerosol production product 200 is heated by the heater 130, the aerosol production product 200 generates an aerosol.

[0039] 1 and 2 show components according to this embodiment. Therefore, it will be understood by those skilled in the art that the aerosol generating device 100 may further include other general-purpose components in addition to the components shown in FIGS.

[0040] 1 and 2 show the aerosol generating device 100 as including the heater 130, the heater 130 may be omitted if necessary.

[0041] 1 shows that the battery 110, the control unit 120, the vaporizer 140, and the heater 130 are arranged in a line. Also, FIG. 2 shows that the vaporizer 140 and the heater 130 are arranged in parallel. However, the internal structure of the aerosol generation device 100 is not limited to that shown in FIG. 1 or 2. In other words, the arrangement of the battery 110, the control unit 120, the vaporizer 140, and the heater 130 may be changed depending on the design of the aerosol generation device 100.

[0042] When the aerosol production product 200 is inserted into the aerosol generating device 100, the aerosol generating device 100 activates the vaporizer 140 to generate an aerosol from the vaporizer 140. The aerosol generated by the vaporizer 140 passes through the aerosol production product 200 and is delivered to the user. The vaporizer 140 will be described in more detail below.

[0043] The battery 110 supplies power used when the aerosol generation device 100 operates. For example, the battery 110 supplies power to heat the heater 130 or the vaporizer 140, and supplies power necessary for the operation of the control unit 120. The battery 110 also supplies power necessary for the operation of a display, a sensor, a motor, and the like provided in the aerosol generation device 100.

[0044] The control unit 120 controls the overall operation of the aerosol generation device 100. Specifically, the control unit 120 controls the operation of not only the battery 110, the heater 130, and the vaporizer 140, but also other components provided in the aerosol generation device 100. The control unit 120 can also check the status of each component of the aerosol generation device 100 to determine whether the aerosol generation device 100 is in an operable state.

[0045] The control unit 120 includes at least one processor. The processor may be implemented as an array of multiple logic gates, or as a combination of a general-purpose microprocessor and a memory storing a program executed by the microprocessor. Those skilled in the art will understand that the processor may also be implemented as other types of hardware.

[0046] The heater 130 is heated by power supplied from the battery 110. For example, when the aerosol production product 200 is inserted into the aerosol generating device 100, the heater 130 is located outside the aerosol production product 200. Thus, the heated heater 130 increases the temperature of the aerosol-generating material within the aerosol production product 200.

[0047] The heater 130 may be an electrical resistance heater. For example, the heater 130 has an electrically conductive track, and the heater 130 is heated by passing an electric current through the electrically conductive track. However, the heater 130 is not limited to the above example, and any heater that can be heated to a desired temperature may be used without limitation. Here, the desired temperature may be already set in the aerosol generating device 100, or may be set to the desired temperature by a user.

[0048] Alternatively, the heater 130 may be an induction heater. Specifically, the heater 130 includes an electrically conductive coil for inductively heating the aerosol product, and the aerosol product includes a susceptor that is heated by the induction heater.

[0049] 1 and 2 show the heater 130 as being disposed externally of the aerosol product 200, but is not limited to this. For example, the heater 130 may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and may heat the interior or exterior of the aerosol product 200 depending on the shape of the heating element.

[0050] Furthermore, a plurality of heaters 130 may be disposed in the aerosol generating device 100. In this case, the plurality of heaters 130 may be disposed so as to be inserted inside the aerosol product 200, or may be disposed outside the aerosol product 200. Furthermore, some of the plurality of heaters 130 may be disposed so as to be inserted inside the aerosol product 200, and the rest may be disposed outside the aerosol product 200. Furthermore, the shape of the heater 130 is not limited to the shapes shown in FIGS. 1 and 2, and various shapes may be manufactured.

[0051] The vaporizer 140 heats the liquid composition to generate an aerosol, which is then transmitted to the user through the aerosol product 200. In other words, the aerosol generated by the vaporizer 140 travels along an airflow passage in the aerosol generating device 100, and the airflow passage is configured to allow the aerosol generated by the vaporizer 140 to pass through the aerosol product 200 and be transmitted to the user.

[0052] For example, the vaporizer 140 may include, but is not limited to, a liquid storage unit, a liquid transfer means, and a heating element. For example, the liquid storage unit, the liquid transfer means, and the heating element may be provided in the aerosol generation device 100 as independent modules.

[0053] The liquid storage unit stores a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, or a liquid containing a non-tobacco substance. The liquid storage unit may be fabricated so as to be detachable from the vaporizer 140, or may be fabricated integrally with the vaporizer 140.

[0054] For example, the liquid composition may contain water, solvent, ethyl alcohol, plant extract, fragrance, flavoring, or vitamin mixture. Flavorings include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. Flavorings include components that provide the user with a variety of flavors or tastes. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also contain an aerosol-forming material such as glycerin and propylene glycol.

[0055] The liquid transfer means transfers the liquid composition in the liquid storage portion to the heating element. For example, the liquid transfer means can be a wick such as, but not limited to, cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0056] The heating element is an element for heating the liquid composition transferred by the liquid transfer means. For example, the heating element may be, but is not limited to, a metal hot wire, a metal hot plate, a ceramic heater, or the like. The heating element may also be composed of a conductive filament such as a nichrome wire, and may be arranged in a structure wound around the liquid transfer means. The heating element is heated by supplying electric current, and transfers heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol is generated.

[0057] For example, the vaporizer 140 may be called, but is not limited to, a cartomizer or an atomizer.

[0058] Meanwhile, the aerosol generating device 100 may further include general-purpose components in addition to the battery 110, the control unit 120, the heater 130, and the vaporizer 140. For example, the aerosol generating device 100 includes a display capable of outputting visual information and / or a motor for outputting tactile information. The aerosol generating device 100 also includes at least one sensor (such as a puff sensor, a temperature sensor, or an aerosol product insertion sensor). The aerosol generating device 100 is also fabricated with a structure that allows external air to flow in or internal gas to flow out even when the aerosol product 200 is inserted.

[0059] 1 and 2, the aerosol generating device 100 may form a system together with a separate cradle. For example, the cradle is used to charge the battery 110 of the aerosol generating device 100. Alternatively, the heater 130 may be heated while the cradle and the aerosol generating device 100 are coupled together.

[0060] The aerosol-producing article 200 is similar to a typical combustion-type cigarette. For example, the aerosol-producing article 200 is divided into a first portion containing an aerosol-generating material and a second portion containing a filter or the like. Alternatively, the second portion of the aerosol-producing article 200 may also contain an aerosol-generating material. For example, the aerosol-generating material in the form of granules or capsules may be inserted into the second portion.

[0061] The entire first part is inserted into the aerosol generation device 100, and the second part is exposed to the outside. Alternatively, only a part of the first part, or both the first part and the second part, may be inserted into the aerosol generation device 100. A user inhales the aerosol while holding the second part in their mouth. At this time, the aerosol is generated by outside air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

[0062] As one example, outside air flows in through at least one air passage formed in the aerosol generation device 100. For example, the opening and / or closing of the air passage formed in the aerosol generation device 100 and / or the size of the air passage may be adjusted by the user. This allows the user to adjust the amount of atomization, smoking sensation, etc. As another example, outside air may flow into the aerosol product 200 through at least one hole formed in the surface of the aerosol product 200.

[0063] An example of an aerosol production article 200 will now be described with reference to FIGS.

[0064] 3 and 4 are drawings showing examples of aerosol products.

[0065] 3, the aerosol product 200 comprises a tobacco rod 210 and a filter rod 220. The first portion 21 described above with reference to FIGS. 1 and 2 comprises the tobacco rod 210, and the second portion 22 comprises the filter rod 220.

[0066] Although filter rod 220 is shown in FIG. 3 as a single segment, this is not intended to be limiting. In other words, filter rod 220 may be configured with multiple segments. For example, filter rod 220 may include a first segment that cools the aerosol and a second segment that filters specific components contained in the aerosol. If necessary, filter rod 220 may also include at least one additional segment that performs another function.

[0067] The aerosol product 200 is wrapped in at least one wrapper 240. The wrapper 240 has at least one hole through which external air can enter or internal gas can escape. In one example, the aerosol product 200 is wrapped in a single wrapper 240. In another example, the aerosol product 200 may be wrapped in two or more wrappers 240 one on top of the other. For example, the tobacco rod 210 is wrapped in a first wrapper 241, and the filter rod 220 is wrapped in wrappers 242, 243, and 244. The entire aerosol product 200 may then be repackaged in a single wrapper 245. If the filter rod 220 is composed of multiple segments, each segment may be wrapped in a wrapper 242, 243, or 244.

[0068] The tobacco rod 210 includes an aerosol-forming material. For example, the aerosol-forming material 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 to these. The tobacco rod 210 may also include other additives, such as flavoring agents, humectants, and / or organic acids. A flavoring liquid, such as menthol or a humectant, may also be added to the tobacco rod 210 by being sprayed onto the tobacco rod 210.

[0069] The tobacco rod 210 may be manufactured in various ways. For example, the tobacco rod 210 may be manufactured in a sheet or a strand. Alternatively, the tobacco rod 210 may be manufactured from shredded tobacco, which is a tobacco sheet. The tobacco rod 210 may also be surrounded by a thermally conductive material. For example, the thermally conductive material may be, but is not limited to, a metal foil such as aluminum foil. For example, the thermally conductive material surrounding the tobacco rod 210 uniformly distributes heat transferred to the tobacco rod 210, improving the thermal conductivity of the tobacco rod and thereby improving the tobacco taste. The thermally conductive material surrounding the tobacco rod 210 also functions as a susceptor that is heated by an induction heater. Although not shown in the drawings, the tobacco rod 210 may further include a susceptor in addition to the thermally conductive material surrounding the exterior.

[0070] The filter rod 220 may be a cellulose acetate filter. Meanwhile, the shape of the filter rod 220 is not limited. For example, the filter rod 220 may be a cylindrical rod or a tubular rod with a hollow interior. The filter rod 220 may also be a recessed rod. If the filter rod 220 is composed of multiple segments, at least one of the multiple segments may be manufactured in a different shape.

[0071] The filter rod 220 may also be manufactured to emit a flavor. For example, a flavoring liquid may be sprayed onto the filter rod 220, or a separate fiber coated with a flavoring liquid may be inserted into the filter rod 220.

[0072] The filter rod 220 also includes at least one capsule 230. The capsule 230 generates a flavor or an aerosol. For example, the capsule 230 has a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 230 may be, but is not limited to, a spherical or cylindrical shape.

[0073] If the filter rod 220 includes a segment for cooling the aerosol, the cooling segment is made of a polymer or a biodegradable polymer. For example, the cooling segment may be made of pure polylactic acid, but is not limited thereto. Alternatively, the cooling segment may be made of a cellulose acetate filter with multiple holes. However, the cooling segment is not limited to the above examples and may be any material that can cool the aerosol.

[0074] 4, the aerosol production product 300 further includes a front end plug 330. The front end plug 330 is located on one side of the tobacco rod 310 opposite the filter rod 320. The front end plug 330 prevents the tobacco rod 310 from detaching to the outside and prevents liquefied aerosol from flowing from the tobacco rod 310 into the aerosol generating device (100 in FIGS. 1 and 2) during smoking.

[0075] Filter rod 320 comprises first segment 321 and second segment 322. Here, first segment 321 corresponds to the first segment of filter rod 220 of FIG. 3, and second segment 322 corresponds to the third segment of filter rod 220 of FIG. 3.

[0076] The diameter and overall length of the aerosol product article 300 correspond to the diameter and overall length of the aerosol product article 200 of Figure 3. For example, but not limited to, the length of the front end plug 330 is approximately 7 mm, the length of the tobacco rod 310 is approximately 15 mm, the length of the first segment 321 is approximately 12 mm, and the length of the second segment 322 is approximately 14 mm.

[0077] The aerosol product 300 is wrapped by at least one wrapper 350. The wrapper 350 has at least one hole formed therein through which external air can flow in or internal gas can flow out. For example, the front end plug 330 is wrapped by a first wrapper 351, the tobacco rod 310 is wrapped by a second wrapper 352, the first segment 321 is wrapped by a third wrapper 353, and the second segment 322 is wrapped by a fourth wrapper 354.

[0078] The entire aerosol product 300 may then be repackaged using the fifth wrapper 355. The fifth wrapper 355 has at least one perforation 360 formed therein. For example, but not limited to, the perforation 360 may be formed in the area surrounding the tobacco rod 310. The perforation 360 serves to transfer heat generated by the heater 130 shown in FIGS. 2 and 3 to the interior of the tobacco rod 310.

[0079] The second segment 322 also includes at least one capsule 340. The capsule 340 generates a flavor or an aerosol. For example, the capsule 340 has a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 340 may be, but is not limited to, a spherical or cylindrical shape.

[0080] A pouch according to one embodiment will now be described with reference to the drawings.

[0081] 5 to 7 are views showing the appearance of a pouch 10 according to one embodiment. Fig. 5 is a plan view of the pouch 10 according to one embodiment, Fig. 6 is a perspective view of the pouch 10 of Fig. 5, and Fig. 7 is a side view of the pouch 10 of Fig. 5.

[0082] Referring to Figures 5 to 7, a pouch 10 according to one embodiment includes a liquid composition and a water-soluble film that encases the liquid composition.

[0083] A pouch 10 according to one embodiment includes a water-soluble film 13 that forms the exterior of the pouch 10, forming a space inside the pouch 10. A liquid composition is placed in the space formed inside the pouch 10. For example, as shown in Figures 5 to 7, a pouch 10 according to one embodiment has two water-soluble films 13 whose edges are joined together to form a space inside the pouch 10. However, the pouch 10 is not limited to this, and two or more water-soluble films 13 may be used, or the space inside may be formed by a single water-soluble film 13.

[0084] At least a portion of the water-soluble film 13 is transparent. A user can visually see the liquid composition remaining therein through the transparent portion of the water-soluble film 13. For example, the water-soluble film 13 is transparent due to the inherent physical properties of the material forming the water-soluble film 13. While FIGS. 5 to 7 illustrate examples of a pouch 10 formed with a transparent water-soluble film 13 throughout its entire area, the present invention is not limited thereto. In another example, the water-soluble film 13 includes a separate transparent area formed of a material different from the water-soluble film 13.

[0085] The water-soluble film 13 refers to a flexible film that has the property of being dissolved upon contact with water. The water-soluble film 13 includes a water-soluble polymer. For example, the water-soluble film includes one or more water-soluble polymers selected from the group consisting of polyvinyl alcohol, polyvinylpyrrolidone, sodium alginate, pullulan, xanthan gum, polyethylene oxide, starch or a starch derivative, gelatin, and alkyl cellulose.

[0086] Here, alkyl cellulose means at least one selected from the group consisting of methyl cellulose, hydroxypropyl methyl cellulose, carboxymethyl cellulose, hydroxymethyl cellulose, and hydroxypropyl cellulose.

[0087] The water-soluble film 13 contains an additive that improves heat resistance. The additive is one or more selected from the group consisting of silicon, silica, calcium chloride, zeolite, and clay. Here, the clay is selected from saponite (SPT), montmorillonite (MMT), hectorite (SWN), water-soluble bentonite (PGV), mica, and mixtures thereof.

[0088] For example, the water-soluble film 13 is manufactured by mixing 5 to 20 parts by weight of a water-soluble polymer and 1 to 3 parts by weight of an additive with 100 parts by weight of distilled water, casting the resulting homogeneous slurry, and then drying it.

[0089] A liquid composition that generates an aerosol when heated is located within the interior space of pouch 10. As will be described below, the liquid composition within pouch 10 is expelled to the exterior of pouch 10, and an external heating element heats the expelled liquid composition, thereby generating an aerosol.

[0090] The liquid composition is equally applicable to the above description of Figures 1 and 2. For example, the liquid composition may contain water, solvent, ethyl alcohol, plant extract, fragrance, flavoring agent, or vitamin mixture. Flavoring agents include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. Flavoring agents include ingredients that provide the user with a variety of flavors or tastes. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also contain an aerosol-forming substance such as glycerin and propylene glycol.

[0091] The pouch 10 according to one embodiment includes a support 14 located inside the pouch 10 and supporting the shape of the pouch 10. The support 14 may be made of, but is not limited to, metal, plastic, and / or paper. The support 14 is located inside the pouch 10 and prevents the shape of the pouch 10 from being deformed due to the consumption of the liquid composition.

[0092] The outer shape of pouch 10 is formed from flexible water-soluble film 13, and is subject to deformation depending on the amount of liquid composition contained therein. When a sufficient amount of liquid composition remains inside pouch 10, the outer shape of pouch 10 is maintained due to the volume occupied by the liquid composition. However, when a small amount of liquid composition remains, the outer shape of pouch 10 is not maintained. If pouch 10 does not maintain its shape, the liquid composition inside pouch 10 is not smoothly released to the outside, which may result in unwanted liquid composition remaining inside pouch 10. There is also a risk that water-soluble film 13 may burst due to external pressure. Support 14 minimizes deformation of pouch 10, thereby preventing unwanted liquid composition from remaining inside pouch 10 and preventing water-soluble film 13 from bursting.

[0093] 5 to 7, a plurality of supports 14 are disposed spaced apart from one another inside the pouch 10. The supports 14 extend in the z-axis direction, and both ends of the supports 14 contact the inner surface of the water-soluble film 13. However, this is not limited thereto, and the shape, arrangement, and number of the supports 14 may be modified in various ways as long as the shape of the pouch 10 is maintained. For example, the cross-sectional area of ​​one end of the support 14 is larger than the cross-sectional area between both ends of the support 14. As another example, the plurality of supports 14 may be disposed to extend in different directions. As yet another example, the pouch 10 may include a single support 14.

[0094] The pouch 10 according to one embodiment is detachably coupled to the heating section 141 of the vaporizer, and serves as the liquid storage section. A vaporizer including the pouch 10 according to one embodiment will be described below with reference to Figures 8 and 9.

[0095] FIG. 8 is a cross-sectional view of a vaporizer according to one embodiment coupled with the pouch 10 shown in FIG.

[0096] 8, a vaporizer 140 according to an embodiment includes a pouch 10 and a heating unit 141. The heating unit 141 is detachably connected to the pouch 10 to heat the liquid composition. The same applies to the vaporizer according to the embodiment as described above with reference to FIGS. 1 and 2.

[0097] The heating unit 141 includes a liquid transfer means 143 and a heating element 142. The liquid transfer means 143 transfers the liquid composition in the liquid storage unit to the heating element 142. For example, the liquid transfer means 143 may be a wick such as, but not limited to, cotton fiber, ceramic fiber, glass fiber, or porous ceramic. The liquid transfer means 143 absorbs the liquid composition, and the liquid composition absorbed by the liquid transfer means 143 moves toward the heating element 142.

[0098] The heating element 142 is an element for heating the liquid composition transferred by the liquid transfer means 143. For example, the heating element 142 may be, but is not limited to, a metal hot wire, a metal hot plate, a ceramic heater, or the like. The heating element 142 may also be made of a conductive filament such as a nichrome wire, and may be arranged in a structure in which it is wound around the liquid transfer means 143. The heating element 142 is heated by the supply of electric current, and transfers heat to the liquid composition in contact with the heating element 142, heating the liquid composition. As a result, an aerosol is generated.

[0099] The water-soluble film 13 according to the embodiment includes a first connecting part 11 connected to the heating part 141. For example, the first connecting part 11 is an elastic ring-shaped member. One surface of the ring-shaped first connecting part 11 is attached to the water-soluble film 13 of the pouch 10. At this time, a hole smaller than the ring size of the first connecting part 11 is formed in the heating part 141, and the first connecting part 11 is connected to the heating part 141 in a compressed state by passing through the hole of the heating part 141. Because the water-soluble film 13 is flexible and stretchable, only the first connecting part 11 stretches to pass through the hole of the heating part 141.

[0100] However, the manner in which the first coupling part 11 and the heating part 141 are coupled together is not limited thereto. For example, the first coupling part 11 may be a hard member and may be coupled to the heating part 141 by a forced fitting method.

[0101] A hole is formed in the first connecting part 11 when it is connected to the heating part 141. To this end, the heating part 141 includes a needle tip for forming the hole in the first connecting part 11. The liquid composition in the pouch 10 is discharged to the outside of the pouch 10 through the hole formed in the first connecting part 11. The liquid composition discharged through the hole formed in the first connecting part 11 moves toward the heating element 142 through the liquid transmitting means 143. Here, the first connecting part 11 comes into contact with the liquid transmitting means 143 when it is connected to the heating part 141.

[0102] The heating unit 141 further includes an insulating portion 144 disposed between the pouch 10 and the heating element 142. The insulating portion 144 blocks at least a portion of the heat transferred from the heating element 142 to the pouch 10. The water-soluble film 13 of the pouch 10 lacks heat resistance due to the characteristics of its material, and may be damaged if exposed to excessive heat. The insulating portion 144 blocks the heat generated by the heating element 142, thereby preventing the water-soluble film 13 of the pouch 10 from being exposed to excessive heat.

[0103] The heat insulating portion 144 has a shape surrounding the heating element 142 to improve the heat insulating effect. In this case, the liquid transmitting means 143 penetrates the heat insulating portion 144. A hole through which the liquid transmitting means 143 penetrates is formed in the heat insulating portion 144.

[0104] The insulating portion 144 includes a plastic material with excellent thermal insulation properties. For example, the insulating portion 144 may include one or more plastics selected from the group consisting of polycarbonate (PC), acrylonitrile butadiene styrene (ABS), polyetheretherketone (PEEK), polysulfone (PSU), liquid crystal polymer (LCP), polyetherimide (PEI), polyethersulfone (PES), polyphenylenesulfone (PPS), and polyimide (PI). However, the insulating portion 144 is not limited thereto. The insulating portion 144 may include any plastic that can block heat transfer from the heating element 142 toward the pouch 10.

[0105] The heating unit 141 includes at least one rib 145. The rib 145 is formed on one side of the heating unit 141 and extends from the heating element 142 toward the pouch 10. The pouch 10 includes a second connecting portion 12 connected to the rib 145. The rib 145 fixes the position of the pouch 10 connected to the heating unit 141. Because the water-soluble film 13 of the pouch 10 is flexible and stretchable, even when the pouch 10 is connected to the heating unit 141 by the first connecting portion 11, the position of a portion relatively far from the first connecting portion 11 may not be fixed. The rib 145 is further connected to the second connecting portion 12 of the pouch 10, thereby fixing the position of the pouch 10.

[0106] The heating unit 141 includes a plurality of ribs 145, and the pouch 10 includes a plurality of second connecting portions 12 for connecting to the plurality of ribs 145. The second connecting portions 12 include holes formed on the edge of the pouch 10. The ribs 145 of the heating unit 141 are connected to the pouch 10 by passing through the holes of the second connecting portions 12. However, the method for connecting the second connecting portions 12 and the ribs 145 is not limited thereto. For example, the second connecting portions 12 are connected to the ribs 145 using a Velcro (registered trademark) connecting method.

[0107] FIG. 9 is a cross-sectional view of a vaporizer according to another embodiment.

[0108] 9, a vaporizer 140 includes a pouch 10 and a heating unit 141 that is detachably connected to the pouch 10 and can heat the liquid composition. The same applies to the vaporizer shown in FIG. 9 as described above with reference to FIG. 8.

[0109] The vaporizer further includes a pressure unit 147 that applies pressure to the pouch 10 in a direction toward the heating element 142. The pressure unit 147 pressurizes the flexible pouch 10 so that the liquid composition in the pouch 10 is transferred entirely to the heating element 142 without remaining inside the pouch 10. Fig. 9 illustrates an example in which the pressure unit 147 pressurizes the pouch 10 using an elastic member, but the present invention is not limited to this. As another example, the pressure unit 147 is an electrically operated pressure member.

[0110] When the vaporizer includes the pressurized portion 147, the pouch 10 does not include an internal support. The pressurized portion 147 completely transfers the liquid composition to the heating element 142, thereby maintaining the shape of the pouch 10 and reducing the need for a support to aid in the transfer of the liquid composition.

[0111] The vaporizer includes a cover 146. Here, the pressurizing unit 147 is disposed on the inner surface of the cover 146. The cover 146 separates the pouch 10 from the outside after the pouch 10 is coupled to the heating unit 141. This prevents the water-soluble film 13 from being ruptured by external factors. While FIG. 9 shows an example in which the cover 146 operates like a hinged door, the present invention is not limited thereto. As another example, the cover 146 may operate in a sliding manner.

[0112] In one embodiment, the vaporizer is detachably coupled to a pouch 10 containing a liquid composition. Therefore, when the liquid composition is consumed, only the pouch 10 can be replaced, and the heating unit 141 can be used continuously. In addition, the pouch 10 includes a water-soluble film 13, which is exposed to water and can be easily and economically disposed of. The water-soluble film 13 of the pouch 10 is lightweight and relatively flexible in shape, making it easier to replace than a rigid liquid storage unit, and it can hold a relatively large amount of liquid composition.

[0113] FIG. 10 is a diagram showing an example of the aerosol generating device 100 to which the vaporizer 140 of FIG. 9 is combined.

[0114] 10, the aerosol generating device 100 includes a battery 110, a control unit 120, a heater 130, and a vaporizer 140. An aerosol product 200 (e.g., a cigarette) is inserted into the internal space of the main body of the aerosol generating device 100. The same applies to the aerosol generating device 100 shown in FIG. 10 as described above with reference to FIGS. 1 and 2.

[0115] The vaporizer 140 is detachably connected to the main body of the aerosol generating device 100. When the aerosol production product 200 is inserted into the aerosol generating device 100, the aerosol generating device 100 activates the vaporizer 140 to generate aerosol from the vaporizer 140. The aerosol generated by the vaporizer 140 passes through the aerosol production product 200 inserted into the main body of the aerosol generating device 100 and is delivered to the user.

[0116] 10 illustrates a heater 130 for heating the aerosol product 200 inserted into the main body of the aerosol generation device 100, but the heater may be omitted from the aerosol generation device 100. If the heater is omitted from the aerosol generation device 100, the high-temperature aerosol generated in the vaporizer 140 passes through the aerosol product 200 and indirectly heats the aerosol product 200. At this time, the tobacco rod of the aerosol product 200 contains a plurality of tobacco granules.

[0117] The tobacco granules are produced by wet extrusion of a mixture of tobacco material, a pH adjuster, and a solvent. The tobacco granules have a diameter of about 0.5 to about 1.5 mm. Examples of the tobacco material include tobacco leaf, tobacco vein, expanded tobacco, shredded tobacco, flat tobacco, reconstituted tobacco, tobacco extract, and combinations thereof.

[0118] The tobacco granules have a basic pH due to the pH adjuster. For example, the tobacco granules have a pH value of about 7.0 to about 9.0. A portion of the nicotine contained in the tobacco substance is converted from nicotine salt to freebase nicotine by the pH adjuster. Freebase nicotine has a relatively low boiling point and is highly volatile compared to nicotine salt. Therefore, the tobacco granules generate nicotine vapor even under relatively low heating conditions.

[0119] The pH adjuster may include one or more of alkali metal carbonates, alkaline earth metal carbonates, alkali metal bicarbonates, alkaline earth metal bicarbonates, alkali metal hydroxides, alkaline earth metal hydroxides, alkali metal phosphates, alkaline earth metal phosphates, alkali metal monohydrogen phosphates, and alkaline earth metal monohydrogen phosphates. For example, the pH adjuster may include one or more of sodium carbonate, potassium carbonate, calcium carbonate, sodium hydroxide, potassium hydroxide, calcium hydroxide, and calcium oxide.

[0120] The tobacco granules further include a binder, which binds the tobacco material, pH adjuster, and solvent together, such as hydroxypropyl cellulose (HPC) or hydroxypropyl methylcellulose (HPMC).

[0121] The tobacco granules further include an aerosol-forming material, for example, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

[0122] The plurality of tobacco granules may be disposed in a cavity formed by the surrounding flaps, but this is not a limitation. For example, the plurality of tobacco granules may be embedded between filter material. The filter material may include fiber bundles of cellulose acetate fibers. The plurality of tobacco granules may be disposed in a uniformly dispersed form between the cellulose acetate fibers.

[0123] In another example, the filter material includes a paper sheet that is wound up and positioned inside the tobacco rod, with the central axis of the wound paper sheet parallel to the longitudinal direction of the aerosol-producing article 200. A plurality of tobacco granules are uniformly dispersed within the wound paper sheet.

[0124] FIG. 11 is a block diagram of an aerosol generating device 1100 according to another embodiment.

[0125] The aerosol generating device 1100 includes a control unit 1110, a sensing unit 1120, an output unit 1130, a battery 1140, a heater 1150, a user input unit 1160, a memory 1170, and a communication unit 1180. However, the internal structure of the aerosol generating device 1100 is not limited to that shown in Fig. 11. That is, a person skilled in the art would understand that some of the components shown in Fig. 11 may be omitted or new components may be added depending on the design of the aerosol generating device 1100.

[0126] The sensing unit 1120 senses the state of the aerosol generating device 1100 or the state around the aerosol generating device 1100, and transmits the sensed information to the control unit 1110. Based on the sensed information, the control unit 1110 controls the aerosol generating device 1100 to perform various functions such as controlling the operation of the heater 1150, restricting smoking, determining whether to insert an aerosol product (e.g., cigarette, cartridge, etc.), and displaying notifications.

[0127] The sensing unit 1120 includes at least one of a temperature sensor 1122, an insertion sensor 1124, and a puff sensor 1126, but is not limited thereto.

[0128] The temperature sensor 1122 senses the temperature to which the heater 1150 (or the aerosol-generating substance) is heated. The aerosol-generating device 1100 may include a separate temperature sensor that senses the temperature of the heater 1150, or the heater 1150 itself may function as a temperature sensor. Alternatively, the temperature sensor 1122 may be disposed around the battery 1140 so as to monitor the temperature of the battery 1140.

[0129] The insertion detection sensor 1124 detects the insertion and / or removal of an aerosol product. For example, the insertion detection sensor 1124 may include at least one of a film sensor, a pressure sensor, an optical sensor, a resistive sensor, a capacitive sensor, an inductive sensor, and an infrared sensor, and detects a change in signal due to the insertion and / or removal of an aerosol product.

[0130] The puff sensor 1126 senses a user's puff based on various physical changes in the airflow passage or channel, such as a temperature change, a flow rate change, a voltage change, or a pressure change.

[0131] The sensing unit 1120 further includes at least one of a temperature / humidity sensor, an air pressure sensor, a geomagnetic sensor, an acceleration sensor, a gyroscope sensor, a position sensor (e.g., GPS), a proximity sensor, and an RGB (illuminance) sensor in addition to the above-described sensors (temperature sensor 1122, insertion sensor 824, and puff sensor 1126). The function of each sensor can be intuitively inferred by a skilled artisan from its name, and therefore a detailed description thereof will be omitted.

[0132] The output unit 1130 outputs and provides to a user information about the status of the aerosol generating device 1100. The output unit 1130 includes, but is not limited to, at least one of a display unit 1132, a haptic unit 1134, and an audio output unit 1136. When the display unit 1132 and the touchpad form a layered structure to form a touch screen, the display unit 1132 is used as an input device in addition to an output device.

[0133] The display unit 1132 visually provides a user with information about the aerosol generating device 1100. For example, the information about the aerosol generating device 1100 refers to various information such as the charge / discharge status of the battery 1140 of the aerosol generating device 1100, the preheating status of the heater 1150, the insertion / removal status of an aerosol product, or a status that restricts the use of the aerosol generating device 1100 (e.g., detection of an abnormal item), and the display unit 1132 outputs the information to the outside. The display unit 1132 is, for example, a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), etc. The display unit 1132 may also be in the form of an LED light emitting element.

[0134] The haptic unit 1134 converts an electrical signal into a mechanical or electrical stimulus to tactilely provide the user with information about the aerosol generating device 1100. For example, the haptic unit 1134 includes a motor, a piezoelectric element, or an electrical stimulation device.

[0135] The acoustic output unit 1136 audibly provides the user with information about the aerosol generation device 1100. For example, the acoustic output unit 1136 converts an electrical signal into an acoustic signal and outputs it to the outside.

[0136] The battery 1140 supplies power used to operate the aerosol generating device 1100. The battery 1140 supplies power to heat the heater 1150. The battery 1140 also supplies power necessary for the operation of other components included in the aerosol generating device 1100 (e.g., the sensing unit 1120, the output unit 1130, the user input unit 1160, the memory 1170, and the communication unit 1180). The battery 1140 is a rechargeable battery or a disposable battery. For example, the battery 1140 may be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0137] The heater 1150 receives power from the battery 1140 and heats the aerosol-generating material. Although not shown in Fig. 11, the aerosol-generating device 1100 may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of the battery 1140 and supplies it to the heater 1150. Furthermore, when the aerosol-generating device 1100 generates aerosol by an induction heating method, the aerosol-generating device 1100 may further include a DC / AC converter that converts the DC power supply of the battery 1140 into AC power supply.

[0138] The control unit 1110, the sensing unit 1120, the output unit 1130, the user input unit 1160, the memory 1170, and the communication unit 1180 perform their functions by receiving power from a battery 1140. Although not shown in Fig. 11, the device further includes a power conversion circuit, for example, an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the battery 1140 and supplies it to each component.

[0139] In one embodiment, heater 1150 is formed of any suitable electrically resistive material, such as, but not limited to, metals or metal alloys including titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, etc. Additionally, heater 130 may be embodied as, but not limited to, a metal hot wire, a metal hot plate with an electrically conductive track disposed thereon, a ceramic heating element, etc.

[0140] In another embodiment, heater 1150 is an induction heater, for example, heater 1150 includes a susceptor that generates heat through a magnetic field applied by a coil to heat the aerosol-generating material.

[0141] The user input unit 1160 receives information input by a user or outputs information to a user. For example, the user input unit 1160 may be, but is not limited to, a keypad, a dome switch, a touchpad (such as a contact-type capacitance type, a pressure-type resistive film type, an infrared sensing type, a surface ultrasonic conduction type, an integral tension measurement type, or a piezoelectric effect type), a jog wheel, or a jog switch. Although not shown in FIG. 11 , the aerosol generating device 1100 may further include a connection interface such as a USB (universal serial bus) interface, through which the aerosol generating device 1100 can connect to other external devices to send and receive information or charge the battery 1140.

[0142] The memory 1170 is hardware that stores various data processed within the aerosol generating device 1100, and stores data that has been processed by the control unit 1110 and data to be processed by the control unit 1110. The memory 1170 includes at least one type of recording medium selected from the group consisting of flash memory type, hard disk type, multimedia card micro type, card-type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk. The memory 1170 stores the operating time of the aerosol generating device 1100, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data regarding the user's smoking pattern.

[0143] The communication unit 1180 includes at least one component for communication with other electronic devices. For example, the communication unit 1180 includes a short-range communication unit 1182 and a wireless communication unit 1184.

[0144] The short-range communication unit 1182 includes, but is not limited to, a Bluetooth (registered trademark) communication unit, a BLE (Bluetooth (registered trademark) Low Energy) communication unit, a short-range wireless communication unit, a WLAN (Wi-Fi) communication unit, a ZigBee communication unit, an infrared (IrDA, infrared Data Association) communication unit, a WFD (Wi-Fi Direct) communication unit, a UWB (ultra wideband) communication unit, an Ant+ communication unit, etc.

[0145] The wireless communication unit 1184 includes, but is not limited to, a cellular network communication unit, an Internet communication unit, a computer network (e.g., a LAN or WAN) communication unit, etc. The wireless communication unit 1184 can identify and authenticate the aerosol generating device 1100 within the communication network using subscriber information (e.g., an International Mobile Subscriber Identity (IMSI)).

[0146] The controller 1110 controls the overall operation of the aerosol generating device 1100. In one embodiment, the controller 1110 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 executed by the microprocessor. Those skilled in the art will understand that the controller 1110 may also be implemented as other types of hardware.

[0147] The control unit 1110 controls the temperature of the heater 1150 by controlling the supply of power from the battery 1140 to the heater 1150. For example, the control unit 1110 controls the power supply by controlling the switching of a switching element between the battery 1140 and the heater 1150. In another example, a heating direct circuit may control the power supply to the heater 1150 in accordance with a control command from the control unit 1110.

[0148] The control unit 1110 analyzes the results sensed by the sensing unit 1120 and controls subsequent processing. For example, the control unit 1110 controls the power supplied to the heater 1150 to start or stop operation of the heater 1150 based on the results sensed by the sensing unit 1120. As another example, the control unit 1110 controls the amount of power supplied to the heater 1150 and the time for which the power is supplied based on the results sensed by the sensing unit 1120 so that the heater 1150 is heated to a predetermined temperature or maintained at an appropriate temperature.

[0149] The control unit 1110 controls the output unit 1130 based on the results sensed by the sensing unit 1120. For example, when the number of puffs counted through the puff sensor 1126 reaches a predetermined number, the control unit 1110 notifies the user through at least one of the display unit 1132, the haptic unit 1134, and the audio output unit 1136 that the aerosol generating device 1100 will soon be finished.

[0150] An embodiment may also be embodied in the form of a recording medium containing computer-executable instructions, such as a program module executed by a computer. Computer-readable media are any available media accessible by a computer, including both volatile and nonvolatile media, and detachable and non-detachable media. Computer-readable media also include both computer recording media and communication media. Computer recording media include both volatile and non-volatile, detachable and non-detachable media embodied in any method or technology for storing information, such as computer-readable instructions, data structures, program modules, or other data. Communication media typically include computer-readable instructions, data structures, program modules, or other data in a modulated data signal, or other transmission mechanism, and include any information delivery media.

[0151] The above description of the embodiments is merely illustrative, and those skilled in the art will understand that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the invention should be determined by the appended claims, and all differences within the scope of the claims should be construed as being included in the scope of protection defined by the claims.
