Description

[Technical field]

[0001] The present disclosure relates to aerosol products and aerosol generating devices. [Background technology]

[0002] Recently, there has been an increasing demand for alternative methods to overcome the shortcomings of conventional cigarettes. One of the alternative methods to overcome the shortcomings of conventional cigarettes is a hybrid type aerosol generating system that uses both a cartridge and a cigarette.

[0003] The hybrid type aerosol generating system is a system in which aerosol generated by heating a cigarette and aerosol that has flowed into the cigarette from the outside are smoked together.

[0004] In the hybrid type aerosol generating system, most of the aerosol smoked is mechanically generated directly from the cartridge. The hybrid type aerosol generating system has the advantages of being almost free of the unpleasant odor peculiar to the process of heating or steaming a cigarette, having a large amount of atomization, and providing the smoking sensation of a traditional cigarette.

[0005] In order to increase the amount of atomization, since most of the aerosol smoked is mechanically generated directly from the cartridge, a key factor in increasing the amount of atomization in a hybrid type aerosol generation system is that the mechanically generated aerosol is filtered as little as possible as it passes through the inside of the cigarette.

[0006] However, in conventional hybrid type aerosol generating systems, a significant amount of the mechanically generated aerosol is filtered by the tobacco leaves as it passes through the cigarette, resulting in a significant reduction in the amount of atomization.

[0007] In order to solve the above problems, various embodiments provide an aerosol product and an aerosol generating device having a structure that can generate a rich amount of atomization. Summary of the Invention [Means for solving the problem]

[0008] According to one embodiment, an aerosol production article can be provided that includes a tobacco rod, a front end plug disposed on one side of the tobacco rod, a filter rod disposed on the other side of the tobacco rod, and an aerosol transport tube disposed inside the tobacco rod through which the aerosol travels. Effect of the Invention

[0009] As described above, the aerosol product and the aerosol generating device according to one aspect of the present disclosure can prevent a significant decrease in the amount of atomization as the aerosol passes through the inside of the tobacco rod.

[0010] Therefore, the user can feel a rich amount of atomization as well as the taste and aroma characteristic of cigarettes. [Brief description of the drawings]

[0023] The device may further include an aerosol generating unit for generating an aerosol by heating a liquid composition, and the aerosol generated from the aerosol generating unit may flow into the aerosol product through the front end plug.

[0024] Since the present disclosure can be modified in various ways and can have various embodiments, a specific embodiment will be illustrated and described in detail in the detailed description. However, this is not intended to limit the present disclosure to a specific embodiment, and it should be understood that the present disclosure includes all modifications, equivalents, or alternatives within the spirit and technical scope of the present disclosure.

[0025] The terms used throughout the specification are merely for describing specific embodiments and are not intended to limit the present disclosure. The singular term includes the plural term unless the context clearly indicates otherwise. Throughout the specification, the terms "include" or "have" are intended to specify the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should be understood not to preclude the presence or additional possibility of one or more other features, numbers, steps, operations, components, and parts, or combinations thereof.

[0026] Hereinafter, a preferred embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. Note that in the accompanying drawings, the same components are represented by the same reference numerals as much as possible. Also, detailed descriptions of known functions and configurations that may obscure the gist of the present disclosure will be omitted. For the same reason, some components in the accompanying drawings are exaggerated, omitted, or illustrated in a schematic manner.

[0027] The following describes an aerosol product according to one embodiment of the present disclosure.

[0028] FIG. 1 is a schematic perspective view of an exposed aerosol product according to a first embodiment of the present disclosure, FIG. 2 is a modified front end plug of the first embodiment of the present disclosure, FIG. 3 is a cross-sectional view of the aerosol product according to the first embodiment of the present disclosure, and FIG. 4 is a view taken along BB in FIG. 3.

[0029] 1 to 4, an aerosol product 100 according to a first embodiment of the present disclosure may include a front end plug 110, a tobacco rod 130, a filter rod 150, an aerosol delivery tube 160, and a wrapper 170. Here, a person having ordinary skill in the art related to this embodiment will understand that the aerosol product 100 may further include other general components in addition to the components shown in FIGS.

[0030] The aerosol production product 100 according to this embodiment may be inserted into an aerosol generating device 300 (see FIGS. 18 and 19) described below and heated. At this time, when the aerosol production product 100 is heated, mainstream smoke is delivered to a user. The mainstream smoke is an airflow flowing from upstream to downstream inside the aerosol production product 100. Here, upstream means the front end plug 110 side, and downstream means the filter rod 150 side. A user of the aerosol production product 100 can inhale the mainstream smoke through the downstream end of the aerosol production product 100.

[0031] The aerosol product article 100 may be formed in a cylindrical shape, where the diameter of the aerosol product article 100 may be between 4.7 mm and 9.9 mm. The front end plug 110, the tobacco rod 130 and the filter rod 150 may also be cylindrical with a diameter between 4.7 mm and 9.9 mm.

[0032] Additionally, the aerosol product 100 may have a length between 35mm and 60mm. The front end plug 110 may have a length between 4mm and 9mm. The tobacco rod 130 may have a length between 12mm and 19mm, and the filter rod 150 may have a length between 19mm and 32mm.

[0033] The values ​​for the shape, diameter, and length of the aerosol product 100 and components are shown as examples, but are not necessarily limited thereto. The shapes and values ​​of the aerosol product 100 may be modified within the scope of those skilled in the art.

[0034] The front end plug 110 may be located at the upstream end of the aerosol product 100 and may prevent the tobacco rod 130 from detaching from the aerosol product 100. The front end plug 110 may be located at the upstream end of the tobacco rod 130 opposite the filter rod 150 centered about the tobacco rod 130.

[0035] The front end plug 110 prevents impurities from entering the tobacco rod 130 from the outside, and prevents aerosol liquefied during smoking from flowing into the aerosol generating device 300 (see Figures 18 and 19).

[0036] Additionally, when the aerosol production article 100 is inserted into the aerosol generation device 300 , the front end plug 110 can support the aerosol production article 100 such that the aerosol production article 100 is fixed to the aerosol generation device 300 .

[0037] The front end plug 110 may include a crimped sheet (not shown). Here, the crimped sheet may be a sheet made of a polymeric material. For example, the polymeric material may include at least one of paper, cellulose acetate, lyocell, and polylactic acid. However, the polymeric material is not necessarily limited thereto, and may not include a crimped sheet depending on the front end plug structure.

[0038] The crimped sheet of the front end plug 110 may be impregnated with aerosol producing qualities as described below. Additionally, other additives such as flavorants, humectants and / or organic acids and flavoring liquids may be included in the front end plug 110 and absorbed into the crimped sheet.

[0039] The aerosol product quality included in the front end plug 110 may exclude nicotine. For example, the front end plug 110 may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the aerosol product quality included in the front end plug 110 is not necessarily limited thereto. For example, the front end plug 110 may include a mixture of glycerin and propylene glycol in a ratio of approximately 8:2, but is not limited to the aforementioned ratio.

[0040] The front end plug 110 may be a cellulose acetate filter. For example, the front end plug 110 may be made by adding a plasticizer such as triacetin to cellulose acetate tow. The cellulose acetate tow may also contain the above-mentioned aerosol production quality. In addition, other additives such as flavoring agents, humectants, and / or organic acids may also be included. However, the material and type of the front end plug 110 are not necessarily limited thereto and may be changed within the scope of what can be adopted by those skilled in the art.

[0041] In some embodiments, depending on the material of the front end plug 110, the front end plug 110 may be formed with a through hole 111 through which an aerosol flows from the outside to form mainstream smoke inside the aerosol production product 100. For example, when the front end plug 110 includes cellulose acetate tow, as shown in Fig. 2, the front end plug 110 is formed with a through hole 111. Here, the through hole 111 may have a circular or Y-shaped cross section, but the cross-sectional shape of the through hole is not necessarily limited thereto and may have various cross-sectional shapes.

[0042] In some embodiments, when the front end plug 110 comprises a crimped sheet impregnated with an aerosol production quality, the front end plug 110 may not have holes formed therein, as shown in FIG.

[0043] In this case, when a portion of the aerosol product 100 is inserted into the aerosol generating device 300, the aerosol generated from the aerosol generating device 300 flows into the aerosol product 100 through the front end plug 110, and the aerosol forms mainstream smoke in the aerosol product 100 and can be delivered to a user. Also, the aerosol generated inside the front end plug 110 including the aerosol product can form mainstream smoke and be delivered to a user.

[0044] Also, a heating unit 370 (see FIG. 19) of the aerosol generating device 300 for heating the aerosol product 100 may be inserted into the through hole of the front end plug 110. In FIG. 19, the heating unit 370 is shown to be disposed around the aerosol product 100, but the disclosure is not limited to this. For example, the heater 370 may be inserted into the through hole 111 in a shape corresponding to the through hole 111 of the front end plug 110.

[0045] The front-end plug 110 may further include a structure for identifying the aerosol product 100. The aerosol product 100 may have a variety of flavors and aromas, and may include a structure for identifying the various types of aerosol product 100 from one another. For example, the front-end plug 110 may include a metal foil for changing the inductance of a coil included in the aerosol generating device 300 to identify the type of aerosol generating article. However, the present invention is not necessarily limited to this, and the structure for identifying the aerosol product 100 may be included in the tobacco rod 130 in addition to the front-end plug 110.

[0046] The tobacco rod 130 is disposed between the front end plug 110 and the filter rod 150 and may include a tobacco medium 131 that generates an aerosol. As the aerosol that flows into the tobacco rod 130 passes through the tobacco rod 130, the aerosol may be mixed with the taste and aroma unique to cigarettes. More specifically, the tobacco medium of the tobacco rod 130 may contain nicotine. As a result, nicotine is mixed into the aerosol as it passes through the tobacco rod 130, allowing a user smoking mainstream smoke to feel the taste and aroma unique to cigarettes.

[0047] For example, the nicotine may be any one or more of free base nicotine or a nicotine salt, and the nicotine may be naturally occurring nicotine or synthetic nicotine.

[0048] Nicotine salts are formed by adding a suitable acid, including an organic acid or an inorganic acid, to nicotine. The acid for forming the nicotine salt is appropriately selected in consideration of the blood nicotine absorption rate, the heating temperature of the heater, the flavor or taste, the solubility, etc. For example, the acid for forming the nicotine salt may be, but is not limited to, 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.

[0049] Meanwhile, the tobacco medium of the tobacco medium part 110 can be manufactured in various forms. For example, the tobacco medium may be manufactured in a sheet or a strand. Also, the tobacco medium 131 may be manufactured in the form of tobacco shreds obtained by cutting a tobacco sheet. Also, the tobacco medium 131 may be manufactured in the form of granules containing tobacco.

[0050] The tobacco rod 130 may be formed in a cylindrical shape. However, the shape of the tobacco rod 130 is not necessarily limited to this, and the tobacco rod 130 may be formed in a bar shape having a cross section of various shapes.

[0051] Here, the tobacco rod 130 may be manufactured by folding a tobacco sheet into a cylindrical shape, or by forming tobacco strands, tobacco shreds, or tobacco granules into a cylindrical shape.

[0052] When the tobacco rod 130 is made of a plurality of tobacco strands formed by cutting a tobacco sheet into small pieces, the tobacco rod 130 may be formed by combining the plurality of tobacco strands in the same direction (parallel) or randomly. Specifically, the tobacco rod 130 may be formed by combining the plurality of tobacco strands to form a plurality of longitudinal channels through which the aerosol can pass. Here, depending on the size and arrangement of the tobacco strands, the longitudinal channels may be uniform or non-uniform.

[0053] The tobacco rod 130 may further include an aerosol product quality to increase the amount of atomization. For example, the aerosol product quality may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

[0054] The tobacco rod 130 may further include a flavoring material to add flavor to the aerosol generated from the tobacco rod. For example, the tobacco rod 130 may include other additives, such as flavoring agents, humectants, and / or organic acids. In addition, a flavoring liquid, such as menthol or a humectant, may be added to the tobacco rod 130 by being sprayed onto the tobacco rod 130.

[0055] Here, the flavoring agent may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander, coffee, etc. Also, the humectant may include glycerin or propylene glycol, etc.

[0056] The tobacco rod 130 may be wrapped with a thermally conductive material. The thermally conductive material can evenly distribute the heat transferred to the tobacco rod 130, improving the thermal conductivity of the heat transferred to the tobacco rod 130, thereby improving the taste of the tobacco. The thermally conductive material may be a metal foil, for example, the thermally conductive material may be aluminum. However, the thermally conductive material is not necessarily limited thereto, and various materials used as thermally conductive materials may be used.

[0057] The filter rod 150 may be located at the downstream end of the aerosol producing article 100 to cool the mainstream smoke containing the aerosol or to filter substances contained in the mainstream smoke. The filter rod 150 may be located at the downstream end of the tobacco rod 130 opposite the front end plug 110, centered about the tobacco rod 130.

[0058] The filter rod 150 may be a single segment or multiple segments. Although the aerosol production article 100 in Figures 1-4 is shown as a single segment, this is not necessarily limited and the filter rod 150 may be multiple segments. For example, if the filter rod 150 is multiple segments, the filter rod 150 may include a segment that cools the aerosol and a segment that filters materials contained in the aerosol generated from the tobacco rod. The filter rod 150 may also include additional segments that perform other functions as needed.

[0059] When the filter rod 150 includes a segment for cooling the aerosol, such a segment may be made of a polymeric or biodegradable polymeric material, including but not limited to gelatin, polyethylene (PE), polypropylene (PP), polyurethane (PU), fluorinated ethylene propylene (FEP), and combinations thereof, and including but not limited to polylactic acid (PLA), polyhydroxybutyrate (PHB), cellulose acetate, polyepsilon caprolactone (PCL), polyglycolic acid (PGA), polyhydroxyalkanoates (PHAs), and starch-based thermoplastics.

[0060] Furthermore, when the filter rod 150 includes a segment for filtering a substance, the segment may have the same configuration as the front end plug 110. For example, the filter rod 150 may be a cellulose acetate filter, which may be made by adding a plasticizer such as triacetin to cellulose acetate tow. However, the material and type of the segment are not necessarily limited thereto, and may be changed within the scope of what can be adopted by those skilled in the art.

[0061] The filter rod 150 may be formed in various shapes. For example, the filter rod 150 may be a cylindrical rod or a tube-type rod having a hollow inside. The filter rod 150 may also be a recess-type rod. Here, when the filter rod 150 is composed of a plurality of segments, each of the plurality of segments may be formed in a different shape.

[0062] The filter rod 150 may be manufactured to emit a flavor. For example, a flavoring liquid may be sprayed onto the filter rod 150, or a separate fiber onto which the flavoring liquid is applied may be included inside the filter rod 150.

[0063] Alternatively, the filter rod 150 may include at least one capsule (not shown). The capsule may generate flavor or generate aerosol. For example, the capsule may be a structure that encases a liquid containing a flavor or flavor with a membrane. Here, the capsule may have a spherical or cylindrical shape, but the shape of the capsule is not necessarily limited thereto.

[0064] According to this embodiment, the aerosol transport tube 160 is disposed inside the tobacco rod 130 , so that the aerosol flowing into the aerosol transport tube 160 can be directly transported from the front end plug 110 to the filter rod 150 .

[0065] Specifically, the aerosol transfer pipe 160 can transfer a portion of the aerosol A flowing in from the outside directly from the front end plug 110 to the filter rod 150 without passing between the tobacco medium 131 of the tobacco rod 130. Here, the "aerosol flowing in from the outside" does not mean the aerosol generated inside the aerosol product 100, but the aerosol generated in the aerosol generating device 300 (see Figures 18 and 19). In addition, the aerosol transfer pipe 160 can transfer a portion of the aerosol generated inside the front end plug 110 directly from the front end plug 110 to the filter rod 150 without passing between the tobacco medium 131 of the tobacco rod 130. In other words, the aerosol transfer pipe 160 can transfer not only the aerosol A flowing in from the outside, but also the aerosol generated inside the front end plug 110.

[0066] The aerosol transfer tube 160 may be disposed inside the tobacco rod 130 such that the inlet of the aerosol transfer tube 160 faces the front end plug 110 and the outlet of the aerosol transfer tube 160 faces the filter rod 150. Here, the inlet of the aerosol transfer tube 160 is where the aerosol flows in, and the outlet of the aerosol transfer tube 160 is where the aerosol flows out.

[0067] In this embodiment, as long as the inlet and outlet of the aerosol transport tube 160 are arranged only in the above-mentioned form, the middle section of the aerosol transport tube 160 may be arranged in various forms. For example, the middle section of the aerosol transport tube 160 may be arranged in various forms, such as in a straight line (see FIG. 3), in a bent form (see FIG. 17), in a meandering form, or in an inclined form. That is, as long as the inlet and outlet of the aerosol transport tube 160 face the front end plug 110 and the filter rod 150, respectively, the middle section of the aerosol transport tube 160 may be in any form. However, preferably, the aerosol transport tube 160 may be formed in a straight line parallel to the extension direction of the tobacco rod 130, as shown in FIG. 3.

[0068] Here, the inlet of the aerosol transfer tube 160 may be located at the portion where the front end plug 110 and the tobacco rod 130 meet, and the outlet of the aerosol transfer tube 160 may be located at the portion where the tobacco rod 130 and the filter rod 150 meet. More specifically, the inlet and outlet of the aerosol transfer tube 160 may be located at both end portions of the tobacco rod 130.

[0069] At least one aerosol transfer tube 160 is disposed inside the tobacco rod 130. As shown in Figure 4, one aerosol transfer tube 160 is disposed inside the tobacco rod 130, or as an additional embodiment shown in Figure 5, multiple aerosol transfer tubes 160 are disposed inside the tobacco rod 130. Here, the multiple aerosol transfer tubes 160 may have the same diameter as each other, or may have different diameters from each other.

[0070] When one aerosol transfer tube 160 is disposed inside the tobacco rod 130, the aerosol transfer tube 160 may be disposed in the center of the tobacco rod 130 so that the aerosol is transferred smoothly.

[0071] The aerosol transfer tube 160 can have a variety of cross-sectional shapes. For example, the aerosol transfer tube 160 can have a circular cross-section, a polygonal cross-section, a Y-shaped cross-section, and the like.

[0072] The aerosol transfer tube 160 may be made of various materials such as paper, metal, fabric, plastic, etc. For example, aluminum may be used as a metal, and thermosetting plastic may be used as a plastic. However, the material of the aerosol transfer tube 160 is not necessarily limited thereto.

[0073] Regarding the size of the aerosol delivery tube 160, the volume of the aerosol delivery tube 160 may be provided as a percentage within a predetermined percentage range in relation to the volume of the tobacco rod 130. Specifically, the volume occupied by the aerosol delivery tube 160 may be 10 to 90 volume percent (%) of the total volume of the tobacco rod 130. If the volume occupied by the aerosol delivery tube 160 is less than 10 volume percent (%), the amount of aerosol directly delivered through the aerosol delivery tube 160 is insufficient, and therefore a sufficient amount of atomization cannot be expected. Also, if the volume occupied by the aerosol delivery tube 160 exceeds 90 volume percent (%), the amount of atomization flowing out to the outside is large, but the taste and aroma unique to the rolled cigarette may not be sufficiently contained in the aerosol through the tobacco rod 130.

[0074] As the aerosol flows into the tobacco rod 130, a considerable amount of the aerosol is filtered by the tobacco medium 131 inside the tobacco rod 130, and the amount of atomization discharged to the outside through the filter rod 150 may be significantly reduced. However, according to the present embodiment, at least a portion of the aerosol can be discharged to the outside through the filter rod 150 directly via the aerosol transfer pipe 160 without passing through the tobacco medium 131. This reduces the reduction in the amount of atomization as the aerosol passes through the aerosol product 100. This also allows users who smoke mainstream smoke to feel a rich amount of atomization along with the taste and aroma unique to cigarettes.

[0075] In addition, in this embodiment, the inlet and outlet of the aerosol transfer tube 160 correspond to the ends of the tobacco rod 130, so that the aerosol can pass smoothly without passing between the tobacco medium 131 of the tobacco rod 130, thereby providing a rich amount of atomization.

[0076] Meanwhile, modified examples of the aerosol transfer tube 160 according to the first embodiment of the present disclosure will be described with reference to Figures 6 to 8. The aerosol transfer tubes 160A, 160B, and 160C in Figures 6 to 8 are located within the tobacco rod 130, but at least one of the inlets or outlets of the aerosol transfer tubes 160A, 160B, and 160C may not correspond to the ends of the tobacco rod 130.

[0077] 6, both the inlet and the outlet of the aerosol transport tube 160A are spaced apart from the end of the tobacco rod 130. Although the aerosol transport tube 160A is located within the tobacco rod 130, the inlet and the outlet of the aerosol transport tube 160A do not correspond to the end of the tobacco rod 130, so that the aerosol transported along the aerosol transport tube 160A may pass through the tobacco medium 131 in a portion thereof.

[0078] 7 does not overlap with the end of the tobacco rod 130, and the aerosol transfer tube 160C in FIG 8 does not overlap with the end of the tobacco rod 130. As a result, the aerosol transferred along the aerosol transfer tubes 160B and 160C may pass through the tobacco medium 131 in a portion of the tube.

[0079] A wrapper 170 can wrap the aerosol product article 100. The wrapper 170 can have at least one perforation (not shown) formed therein to allow outside air to flow into or inside air to flow out of the aerosol product article 100. The aerosol product article 100 can be wrapped in a single wrapper or can be wrapped in multiple wrappers in an overlapping or multiplexed manner.

[0080] The tobacco rod 130 and the filter rod 150 may each be individually wrapped in a different wrapper. If the tobacco rod 130 and the filter rod 150 are individually wrapped, the individually wrapped configuration may be repackaged in another wrapper as a whole.

[0081] The following describes an aerosol product according to a second embodiment of the present disclosure and its modified example.

[0082] FIG. 9 is a cross-sectional view of an aerosol production article according to a second embodiment of the present disclosure, and FIGS. 10 to 12 show variations of the aerosol delivery tube of the second embodiment of the present disclosure.

[0083] Referring to FIG. 9, the aerosol product according to the second embodiment has the same structure as the aerosol product 100 according to the first embodiment, except for the aerosol transport pipe 161, so duplicated descriptions of the same configurations will be omitted.

[0084] 9, the aerosol transport tube 161 may not only be disposed within the tobacco rod 130, but also extend into the front end plug 110. Here, the inlet of the aerosol transport tube 161 may correspond to the upstream end of the front end plug 110, and the outlet of the aerosol transport tube 161 may correspond to the downstream of the tobacco rod 130.

[0085] As a result, a portion of the aerosol A flowing in from the outside can move directly along the aerosol transfer pipe 161 without passing through the inside of the front end plug 110. Therefore, the loss of the aerosol in the process of passing through the front end plug 110 can be further reduced.

[0086] Meanwhile, modified examples of the aerosol transfer tube 161 according to the second embodiment of the present disclosure will be described with reference to Figures 10 to 12. Although the aerosol transfer tubes 161A, 161B, and 161C in Figures 10 to 12 are extended to the front end plug 110, at least one of the inlets or outlets of the aerosol transfer tubes 161A, 161B, and 161C may not correspond to the upstream end of the front end plug 110 and the downstream end of the tobacco rod 130, respectively.

[0087] 10, the inlet of the aerosol transfer tube 161A is separated from the upstream end of the front end plug 110. In FIG 11, the inlet and outlet of the aerosol transfer tube 161B do not correspond to the upstream end of the front end plug 110 and the downstream end of the tobacco rod 130, respectively. Also, in FIG 12, the outlet of the aerosol transfer tube 161C is separated from the right end of the tobacco rod 130 without overlapping therewith.

[0088] The following describes an aerosol product according to a third embodiment of the present disclosure and its modified example.

[0089] FIG. 13 is a cross-sectional view of an aerosol production article according to a third embodiment of the present disclosure, and FIGS. 14 to 16 show variations of the aerosol delivery tube of the third embodiment of the present disclosure.

[0090] Referring to FIG. 13, the aerosol product according to the third embodiment has the same structure as the aerosol product 100 according to the first embodiment, except for the aerosol transport pipe 166, so duplicated descriptions of the same configurations will be omitted.

[0091] 13, the aerosol transfer pipe 166 is not only disposed within the tobacco rod 130, but also extends into the filter rod 150. Here, the inlet of the aerosol transfer pipe 166 corresponds to the upstream end of the tobacco rod 130, and the outlet of the aerosol transfer pipe 166 is located inside the filter rod 150. Here, the outlet of the aerosol transfer pipe 166 does not correspond to the downstream end of the filter rod 150. This is to prevent aerosol from reaching the user directly without being filtered by the filter rod 150.

[0092] As a result, the aerosol that has flowed into the aerosol transport pipe 166 can move without passing through the tobacco rod 130 and without passing through a portion of the filter rod 150. Therefore, the loss of the aerosol during the process of passing through a portion of the filter rod 150 can be further reduced.

[0093] Meanwhile, a modified example of the aerosol transfer pipe 166 according to the third embodiment of the present disclosure will be described with reference to FIGS.

[0094] With reference to Figure 14, the inlet of aerosol transfer tube 166A is spaced from the upstream end of tobacco rod 130. In Figure 15, the inlet of aerosol transfer tube 166B extends into front end plug 110 and corresponds to the downstream end of front end plug 110. In Figure 16, the inlet of aerosol transfer tube 166C extends into a portion of the interior of front end plug 110.

[0095] Hereinafter, an aerosol generating device into which an aerosol production article according to a first embodiment of the present disclosure is inserted will be described.

[0096] FIG. 18 is a perspective view of an aerosol generating device into which an aerosol production article according to the first embodiment of the present disclosure is inserted, and FIG. 19 is a schematic diagram of the aerosol generating device of FIG.

[0097] 18 and 19, the aerosol generating device 300 according to the present embodiment may include a heating unit 370, a power supply unit 330, a control unit 310, and an aerosol generating unit 350. A person having ordinary skill in the art related to the present embodiment may understand that the aerosol generating device 300 may further include other general components in addition to the components shown in Figs. 18 and 19. Meanwhile, in Fig. 19, the power supply unit 330, the control unit 310, and the aerosol generating unit 350 are shown to be arranged in a line, but the arrangement of the power supply unit 330, the control unit 310, and the aerosol generating unit 350 may be changed as necessary.

[0098] The aerosol production article 100 may be inserted into the aerosol generation device 300. The aerosol production article 100 may be fixed to the aerosol generation device 300 by a fixing means. In some embodiments, the fixing means corresponds to the front end plug 110 of the aerosol production article 100. However, other fixing means besides the front end plug 110 may be added.

[0099] The heating unit 370 can heat the aerosol product 100. The heating unit 370 is heated by the power supplied from the power supply unit 330, and thereby the heating unit 370 transfers heat to the aerosol product 100.

[0100] The heating element 370 may be an electrically resistive heater. The heating element 370 may include an electrically conductive track, and the power source provided by the power source 330 may cause an electric current to flow through the electrically conductive track, thereby enabling the heating element 370 to heat the aerosol product article 100.

The heating unit 370 may include at least one of a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, and may heat the interior, exterior, or both of the aerosol product 100 depending on the shape of the at least one heating element included in the heating unit 370.

[0103] The power supply unit 330 supplies power used by the aerosol generating device 300. For example, the power supply unit 330 supplies power to heat the heating unit 370 and supplies power necessary for the operation of the control unit 310. In addition, the power supply unit 330 supplies power necessary for the operation of a display, a sensor, a motor, etc. of the aerosol generating device 300.

[0104] The control unit 310 generally controls the operation of the aerosol generating device 300. Specifically, the control unit 310 controls the operation of the power supply unit 330 and other components included in the aerosol generating unit 350. The control unit 310 can also check the state of each component of the aerosol generating device 300 to determine whether the aerosol generating device 300 is in an operable state.

[0105] The aerosol generating unit 350 heats the liquid composition to generate an aerosol, and the generated aerosol passes through the aerosol producing product 100 and is delivered to a user. In other words, the aerosol generated by the aerosol generating unit 350 can flow into the front end plug 110 of the aerosol producing product 100.

[0106] The aerosol generating unit 350 includes, but is not limited to, a liquid storage unit, a liquid transfer means, and a heating element. For example, the liquid storage unit, the liquid transfer means, and the heating element may be included in the aerosol generating device 300 as independent modules.

[0107] The liquid storage unit can store a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco aroma component, or a liquid containing a non-tobacco substance. The liquid storage unit may be manufactured to be detachable or integral with the aerosol generating device 300.

[0108] When the aerosol generating unit 350 according to an embodiment of the present disclosure contains a liquid including a non-tobacco substance, the liquid composition stored in the liquid storage unit included in the aerosol generating unit 350 may not contain nicotine, and the aerosol generated from the aerosol generating unit 350 may flow into the front-end plug 110 without containing nicotine. In this case, the aerosol not containing nicotine passes through the tobacco rod 130 and adsorbs nicotine, and the aerosol that has passed through the tobacco rod 130 contains nicotine.

[0109] The liquid composition contained in the aerosol generating unit 350 may include water, a solvent, ethanol, a plant extract, a flavoring, a flavoring agent, or a vitamin mixture.
