Description

[Technical field]

[0001] The present invention relates to a gel-like aerosol-generating substrate cartridge that can be inserted into an electrically heated smoking article, an electrically heated smoking article including the same, and an aerosol generating device and system therefor; more specifically, the present invention relates to a gel-like aerosol-generating substrate cartridge that can be inserted into an electrically heated smoking article including a tobacco medium that can generate aerosol by a heating method other than combustion, and that can further generate aerosol by heating, an electrically heated smoking article including the same, and an aerosol generating device and system therefor. [Background technology]

[0002] In recent years, there has been an increasing demand for alternative methods that overcome the shortcomings of conventional cigarettes, such as methods that generate aerosols by heating an aerosol-generating material within a cigarette, rather than by burning a cigarette.

[0003] Generally, the tensile strength of the slurry plate sheet, which is the main raw material of the tobacco medium, is weak, making it difficult to manufacture, and the tobacco medium contains a large amount of humectant, making it physically weak. In addition, the tobacco medium containing liquid such as glycerin is sensitive to the humidity of the surrounding environment due to its hydrophilicity, making it difficult to control the environment during the manufacturing process. There is also a limit to the amount of liquid that can be contained in the tobacco medium.

[0004] It has also been proposed to store liquid in a separate cartomizer in addition to the cigarette containing the tobacco medium, and generate an aerosol so that the user can inhale the aerosol derived from the liquid through the cigarette when inhaling the cigarette (the so-called hybrid type). However, there are difficulties in managing the liquid contained in the cartomizer (such as expiration date and deterioration), and there is a risk of condensation forming in the airflow path through which the aerosol generated from the cartomizer moves, causing contamination.

[0005] Thus, a need exists to provide a liquid within a disposable electrically heated smoking article from which an aerosol can be obtained. Summary of the Invention [Problem to be solved by the invention]

[0033] The present invention can be transformed into various forms and can have various embodiments, and specific embodiments are illustrated in the drawings and will be described in detail in the detailed description. The advantages and features of the present invention, as well as the methods for achieving them, will become apparent from the following detailed description of the embodiments in conjunction with the drawings. However, the present invention is not limited to the embodiments disclosed below, and may be embodied in various forms.

[0034] In the following embodiments, singular expressions include plural expressions unless otherwise clearly specified in the context.

A smoking article includes an upstream end (i.e., the part where air enters) and an opposing downstream end (i.e., the part where air exits). When using a smoking article, a user holds the downstream end of the smoking article in their mouth and can inhale air that is inhaled through the upstream end of the smoking article, passes through the smoking article, and exits at the downstream end. The downstream end is located downstream of the upstream end, while the term "end" can also be described as "terminal end".

[0037] In the drawings, the size of components may be exaggerated or reduced for the sake of convenience. For example, the size and thickness of each component shown in the drawings are arbitrarily shown for the sake of convenience, and the present invention is not necessarily limited to those shown.

[0038] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG. 1 is a block diagram of a semiconductor device according to an embodiment of the present invention;

[0039] Hereinafter, a gel aerosol-generating substrate cartridge insertable into an electrically heated smoking article capable of generating aerosol by heating according to a preferred embodiment of the present invention and an electrically heated smoking article including such a gel aerosol-generating substrate cartridge will be described with reference to the accompanying drawings. For convenience of explanation, the components of the electrically heated smoking article will be described, followed by the gel aerosol-generating substrate cartridge included therein. Here, an electrically heated smoking article is a form in which an aerosol is generated from the smoking article by heating the smoking article by an electric resistance heating method or an induction heating method, etc., rather than by combustion, and the user inhales the aerosol for use. Such a smoking article includes an appropriate amount of aerosol-generating substrate and / or tobacco shreds in the smoking article for inhaling a similar number of times as a conventional cigarette, and after a predetermined amount of aerosol is generated, it does not generate any more aerosol and is disposable by the user.

[0040] The electrically heated smoking article according to the present invention includes, as the aerosol-generating substrate, a gel aerosol-generating substrate containing ordinary tobacco shreds and a liquid composition such as glycerin, as described below. An electrically heated smoking article 50 according to a preferred embodiment of the present invention has a structure in which a tobacco body 58 containing tobacco shreds as an aerosol-generating substrate at an upstream end, a gel aerosol-generating substrate cartridge 56 containing a liquid composition as another aerosol-generating substrate immediately downstream thereof, a paper tube 54 providing an aerosol transfer passage immediately downstream thereof, and a filter 52 acting as a mouthpiece are laminated, and these are wrapped by wrapping paper 60. The relative positions of the gel aerosol-generating substrate cartridge 56 containing the liquid composition and the tobacco body 58 containing tobacco shreds may be reversed.

[0041] The gel aerosol-generating substrate cartridge according to the present invention comprises a gel aerosol-generating substrate containing glycerin and gelatin, which exists in a gel, semi-solid or solid state (hereinafter simply referred to as "gel-state") in a first temperature range including room temperature (e.g., a temperature range of 50°C), changes to a liquid or liquid state in a second temperature range including 70°C (e.g., a temperature range of 50 to 100°C), and vaporizes into an aerosol in a temperature range of 150 to 400°C, a gel container 56a in which the gel aerosol-generating substrate is contained, and wrapping paper 61 which wraps the sides of the gel container 56a in a cylindrical shape having a length of 7 to 20 mm and a diameter of 5 to 8 mm. The cylindrical shape having a length of 7 to 20 mm and a diameter of 5 to 8 mm is a size that conforms to the specifications of ordinary cigarettes or electrically heated smoking articles currently in use, and when a gel aerosol generating substrate cartridge having such specifications is inserted into an electrically heated smoking article 50 and wrapped in a separate wrapping paper 60, from the user's point of view, there is no difference between it and ordinary cigarettes or electrically heated smoking articles.

[0042] Because the tobacco shreds 58a cannot maintain their shape by themselves, they are wrapped in a separate wrapping paper 62 to form a tobacco body 58, which is prepared to be the same size (diameter) as the gel aerosol-generating substrate cartridge 56. The aforementioned filter 52, paper tube 54, gel aerosol-generating substrate cartridge 56 and tobacco body 58 are then wrapped in wrapping paper 60 to obtain an electrically heated smoking article 50 as shown in Figure 1.

[0043] Specifically, the gel aerosol generating base material is a mixture of glycerin and gelatin, and as an example, glycerin PG (Propylene Glycol) or VG (Vegetable Glycerine), or a mixture of PG and VG, is heated and stirred for 30 minutes to reduce the viscosity, and 10 to 50% by weight of gelatin and / or water, which are additives capable of gelling, is added thereto and stirred until the additives are dissolved in the glycerin, to obtain a mixture of glycerin and gelatin and / or water. The mixture maintains a gel, semi-solid or solid state in a first temperature range (temperature range less than about 50°C) including room temperature, changes to a liquid state when heated to a second temperature range (temperature range of 50 to 100°C) including 70°C, and exists in a liquid state when heated further, generating an aerosol at about 150°C or higher.

[0044] As described above, the gel aerosol-generating substrate may further include one or more of water, agar, thickener, starch powder, cellulose, carboxymethyl ethers, natural food flavors, or fruit extracts. In addition, the content of glycerin in the gel aerosol-generating substrate is preferably 50% by weight or more. When water is included, the time required to soften the gelatin and form the mixture of the gel aerosol-generating substrate can be reduced. The mixture may further include agar, which is also advantageous in forming the mixture of the gel aerosol-generating substrate. In addition, the mixture of the gel aerosol-generating substrate may include thickener, starch powder, cellulose, and carboxymethyl ethers as additives. The mixture of the gel aerosol-generating substrate may further include natural food flavors or fruit extracts. In this case, it is possible to add various flavors to the user through the generated aerosol. In any case, it is preferred that the glycerin content of the gel aerosol-generating base mixture be 50% by weight or more, which helps to minimize any burnt taste from the generated aerosol. The gel aerosol-generating base mixture may or may not further include nicotine.

[0045] Here, the gel aerosol generating base material includes a liquid composition consisting of 80-100% glycerin VG and 0-20% glycerin PG by weight, and includes gelatin of 1-6g weight per 100ml of a mixture of 60-80% liquid composition and 20-40% water by volume, and optionally includes a flavoring agent added in an amount of 10% or less by weight of the total liquid composition. Here, the liquid composition is preferably included in the gel container in an amount of 70-120mg. Such a numerical range indicates the amount of liquid composition that can provide an aerosol derived from the liquid composition when a user inhales an aerosol from a tobacco body 58 made of tobacco shredded leaves provided in one electrically heated smoking article. If the gel container 56a contains a liquid composition less than the lower limit (70 mg) as a gel aerosol-generating substrate, the aerosol generated from the liquid composition may be insufficient during the process of the user inhaling the aerosol generated from the tobacco body 58 made of tobacco shredded leaves provided to the electrically heated smoking article, so the liquid composition contained in the gel aerosol-generating substrate cartridge 56 must be equal to or greater than the lower limit (70 mg). If the gel container 56a contains a liquid composition exceeding the upper limit (120 mg), the volume of the gel aerosol-generating substrate, which is a mixture, is too large, making it difficult for the gel container in the gel aerosol-generating substrate cartridge 56 having the above specifications to hold the liquid composition. Therefore, the liquid composition contained in the gel aerosol-generating substrate cartridge must be equal to or less than the upper limit (120 mg). A preferable range is 80 to 110 mg, and a more preferable range is 90 to 105 mg.

[0046] Another feature of the present invention is that the gel aerosol-generating substrate can exist in a liquid state in the manufacturing process as described below, but even when liquefied, the gel container 56a in the gel aerosol-generating substrate cartridge having the above-mentioned specifications has a sufficient moisture absorption rate to maintain the liquid composition having the above-mentioned composition range in the gel aerosol-generating substrate cartridge. In other words, the liquid composition is maintained in the gel container 56a in the gel aerosol-generating substrate cartridge as absorbed with moisture, and does not flow out of the gel aerosol-generating substrate cartridge. Here, moisture absorption means that the gel container is absorbed by the liquid composition, but the moisture does not flow out to the outside. As described below, the filter 52-paper tube 54-gel aerosol-generating substrate cartridge 56-tobacco body 58 are wrapped with wrapping paper 60 to form the electrically heated smoking article 50, and the gel aerosol-generating substrate cartridge 56 is in direct contact with the tobacco body 58, the paper tube 54, and the filter 52 without any separate member upstream or downstream, but the liquid composition absorbed in the gel container 56a in the gel aerosol-generating substrate cartridge 56 is simply absorbed and stored in the gel container, and does not flow out toward the tobacco body 58, the paper tube 54, or the filter 52. For this reason, the liquid composition is absorbed in an amount of 0.13 to 0.32 mg / mm 2 per unit volume of the gel container. 3 The reason for this numerical limit is similar to the reason for the numerical limit for the amount of liquid composition absorbed by the gel container 56a of the present invention. 3 ), the amount of liquid composition absorbed by the gel container 56a is insufficient, and therefore, in the process of the user inhaling the aerosol derived from the tobacco shreds provided in the electrically heated smoking article, the aerosol derived from the gel aerosol-generating substrate may be insufficient. Therefore, the liquid composition absorbed by the gel aerosol-generating substrate cartridge should be within the above lower limit (0.13 mg / mm 3 ) or more. 3) is absorbed into the gel container, the gel container in the gel aerosol-generating substrate cartridge having the above-mentioned specifications will find it difficult to keep the liquid composition absorbed, and there is a risk that the liquid composition will leak out of the gel aerosol-generating substrate cartridge 56.

[0047] The "gel aerosol-generating substrate cartridge" used in the present invention refers to a cartridge 56 having a gel aerosol-generating substrate that exists in a gel state at room temperature, liquefies in a temperature range of 50 to 100° C. including 70° C. as an example, and vaporizes into an aerosol by additional heating in a temperature range of about 150 to 350° C. as an example. As an example, the gel aerosol-generating substrate is a gel mixture of a liquid composition such as glycerin VG (optionally including glycerin PG) that exists in a gel state in a first temperature range including room temperature and changes into a liquid state in a second temperature range including 70° C., gelatin, and water, and when heated by a separate aerosol generating device using electrical induction or resistance heating, the gel aerosol-generating substrate changes into a liquid state, and when additional heating is applied, the liquid composition generates an aerosol. In one preferred embodiment of the present invention, the liquid composition is 100% VG glycerin by weight, and in another preferred embodiment, the liquid composition is 80% VG glycerin and 20% PG glycerin by weight.

[0048] According to another preferred embodiment, the liquid composition is heated and stirred for 30 minutes to reduce the viscosity, and then gelling additives such as gelatin and / or water are added thereto and stirred until the additives are dissolved in the glycerin to obtain a gel mixture in which glycerin is mixed with gelatin and / or water. At this time, the mixture is mixed at a volume ratio of 60-80% liquid composition and 20-40% water, and contains 1-6 g of gelatin per 100 ml of the mixture.

[0049] According to another preferred embodiment, 1g, 1.5g, and 2g of gelatin were each placed in 10ml of cold water to soften the gelatin, and then 50ml of a liquid composition containing 80% glycerin VG and 20% glycerin PG by weight was mixed and dissolved, and the mixture was left at room temperature for 6 hours or more. Even when left at room temperature, gelation proceeded well, and the more the amount of gelatin increased, the more the gelation proceeded. When gelatin was between 1g and 1.5g, viscosity increased and weak gelation proceeded.

[0050] According to another preferred embodiment, 5 g of gelatin was placed in 50 ml of cold water and left to soak for 30 minutes, and then 100 ml of a liquid composition containing 80% glycerin VG and 20% glycerin PG by weight was added, followed by stirring and heating at 75°C for 90 minutes to obtain a gel-like aerosol-generating base material.

[0051] The gel aerosol-generating substrate maintains a gel state in a first temperature range (less than about 50° C.) including room temperature, changes to a liquid state in a second temperature range (temperature range of 50° C. to 100° C.) including 70° C. when heated, and exists in a liquid state when heated to about 120° C. or higher when further heated. As described later, in order to inject the gel aerosol-generating substrate into the gel container 56a, the gel aerosol-generating substrate is heated to a second temperature range during the manufacturing process to be liquefied, and the liquid is sprayed or injected into the gel container 56a with a needle or the like to absorb the liquid into the gel container 56a. Thereafter, the liquid is maintained at a low temperature, for example, about 4° C. for 5 to 10 minutes, or at room temperature for 1 hour or more, so that the liquid absorbed into the gel container 56a changes to a gel state and is dispersed in the form of fine particles on the surface, pores, network, etc. of the gel container 56a.

[0052] Meanwhile, the gel container has sufficient hygroscopicity with respect to the liquid composition of the liquefied aerosol-generating material, so that the liquid composition does not flow out of the gel container. As described above, the gel aerosol-generating substrate is mainly composed of glycerin and gelatin, but preferably further contains water. When water is contained, the time required to form the gel aerosol-generating substrate by softening the gelatin can be reduced. The gel aerosol-generating substrate can further contain agar, which also acts favorably in forming a gel. In addition, the gel aerosol-generating substrate can contain thickeners, starch powder, celluloses, and carboxymethyl ethers as additives. The gel aerosol-generating substrate can further contain natural food flavors or fruit extracts. In this case, it is possible to add various tastes to the user through the generated aerosol. In any case, the content of glycerin in the gel aerosol-generating substrate is preferably 50% by weight or more, which can minimize the burnt taste from the generated aerosol.

[0053] As described above, the liquid composition contains 80-100% VG glycerin and 0-20% PG glycerin by weight, and further contains a flavoring agent added to the liquid composition in an amount of 10% or less based on the total weight of the liquid composition obtained. According to a preferred embodiment, the present invention uses a liquid composition containing 100% VG glycerin by weight. According to another preferred embodiment, the present invention uses a liquid composition containing 80% VG glycerin and 20% PG glycerin by weight. According to another preferred embodiment, the present invention further contains a flavoring agent added to the liquid composition in an amount of 10% or less based on the total weight of the liquid composition obtained. For example, flavorants 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, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang-ylang, sage, spearmint, ginger, coriander, or coffee, etc. Additionally, the liquid composition may or may not contain nicotine.

[0054] According to the present invention, the gel container 56a may be made of various materials. In Figs. 1 and 2, the gel container 56a is shown to be wound up, but this is shown for convenience only, and the configuration of the gel container 56a is not limited thereto. Various types of gel containers 56a may be considered, and basically, the gel container 56a is folded or rolled and pressed into one side of the pipe structure 40 shown in Fig. 3, and is pressed out on the other side in a shape with a slightly narrower cross section, and is wrapped with wrapping paper 61 to obtain a gel container rod 57. Before being introduced into the pipe structure 40, the liquefied gel aerosol-generating base material is absorbed into the gel container 56a through a liquid injection part such as a needle, and the gel container 56a passes through the pipe structure 40 and absorbs or contains the liquefied gel aerosol-generating base material. The gel container 56a is immediately wrapped with wrapping paper 61 on the other side of the pipe structure 40, and is cut to an appropriate length, for example, about 80 mm or 140 mm, to form the gel container rod 57. That is, the gel aerosol-generating base material mixture is heated to a second temperature range including 70° C. to become liquid, and is then injected into the gel container 56a through an injection part such as a needle, and absorbed into the gel container 56a. Before being cut into the gel container rod 57, a suitable cooling process may be performed. Since the gel container 56a has sufficient moisture absorption capacity for the gel aerosol-generating base material in liquid state, the gel aerosol-generating base material in liquid state introduced into the gel container 56a is gelled by maintaining the gel container 56a at room temperature for a suitable time, for example, 1 hour, or at a low temperature, for example, 4° C., for 5 to 10 minutes, after cutting, thereby preventing or minimizing the outflow of the liquid composition from the gel container 56a during subsequent operations (such as cutting into cartridges or wrapping in smoking articles). That is, the gel container rod 57 can be provided in a state in which the gel container 56a containing the gel aerosol-generating substrate in a liquid state is wrapped in wrapping paper 61, and by providing an appropriate cooling structure for the pipe structure, the gel container rod 57 can also be wrapped in wrapping paper 61 while the gel aerosol-generating substrate remains in a gel state within the gel container 56a.In contrast, as described above, the gel container rod 57 can gel and retain the mixture containing the aerosol-generating substrate introduced into the gel container simply by maintaining it within a first temperature range including room temperature for a predetermined period of time, and is cut to a size that can be inserted into an individual smoking article 50, as described below.

[0055] This configuration is a common process in existing cigarette manufacturing lines, and has the advantage that the existing cigarette manufacturing processes and equipment can be used as is. That is, the above-mentioned process can be applied as is to the manufacture of existing filters, paper tubes, and tobacco leaves, and the cartridge 56 can be obtained using such current equipment and steps as is.

[0056] The gel aerosol-generating substrate is introduced into the gel container in a liquid state in a second temperature range of, for example, 50 to 100° C., including 70° C., and is therefore easily absorbed by the gel container described below, and exists in a gel state on the surfaces, pores, and spaces between the networks of the gel container in a first temperature range of, for example, less than 50° C., including room temperature. Therefore, when the gel aerosol-generating substrate cartridge is maintained in the first temperature range including room temperature, there is no possibility or the possibility of the liquid composition contained in the gel aerosol-generating substrate leaking or leaking out of the gel aerosol cartridge can be minimized.

[0057] According to a preferred embodiment, the gel container according to the present invention is made by folding or rolling a strip having a thickness of 2 to 3 mm, which is made of a melamine-based foamed resin, and introducing it into the pipe structure 40 described above to form a cylindrical shape. According to another preferred embodiment, the gel container according to the present invention is made by processing a melamine-based foamed resin into a cylindrical shape, introducing it into the pipe structure 40 described above, and extruding it. The gel container made of a melamine-based foamed resin is more preferably made of a material having a density of 0.01 to 0.013 mg / mm. 3According to the results of an experiment conducted on an electrically heated smoking article including a gel aerosol-generating substrate cartridge corresponding to 100 mg of the liquid composition, the liquid composition was maintained absorbed in the gel container without any problem of leakage to the outside during the experiment, and a much more abundant aerosol was confirmed than in existing heated tobacco products, and sufficient aerosol derived from a larger amount of the liquid composition was confirmed than in existing hybrid types or when the liquid composition was absorbed.

[0058] According to another preferred embodiment, the gel container according to the present invention is made by folding or rolling pulp or a fabric containing pulp into the pipe structure 40 described above to form a cylindrical shape, or by processing the pulp into a cylindrical shape and introducing it into the pipe structure 40 described above to extrude it. The gel container made of pulp or a fabric containing pulp is more preferably made to have a viscosity of 0.25 to 0.4 mg / mm 3 According to the results of an experiment conducted on an electrically heated smoking article including a gel aerosol generating substrate cartridge corresponding to 100 mg of the liquid composition, the liquid composition was maintained absorbed in the gel container without any problem of leakage to the outside during the experiment, and a much more abundant aerosol was confirmed than in existing heated tobacco products, and sufficient aerosol derived from a larger amount of the liquid composition was confirmed than in existing hybrid types or when the liquid composition was absorbed.

[0059] According to another preferred embodiment, the gel container according to the present invention is made by folding or rolling a cotton woven fabric or nonwoven fabric into a cylindrical shape and introducing it into the pipe structure 40 described above, or by processing it into a cylindrical shape and introducing it into the pipe structure 40 and extruding it. The gel container made of the cotton woven fabric or nonwoven fabric is more preferably 0.2 to 0.35 mg / mm 3According to the results of an experiment conducted on an electrically heated smoking article including a gel aerosol generating substrate cartridge corresponding to 100 mg of the liquid composition, the liquid composition was maintained absorbed in the gel container without any problem of leakage to the outside during the experiment, and a much more abundant aerosol was confirmed than in existing heated tobacco products, and sufficient aerosol derived from a larger amount of the liquid composition was confirmed than in existing hybrid types or when the liquid composition was absorbed.

[0060] According to another preferred embodiment, the gel container according to the present invention is made by folding or rolling a woven or nonwoven bamboo fiber fabric into the pipe structure 40 and forming it into a cylindrical shape, or by processing it into a cylindrical shape and then forming it into the pipe structure 40 and extruding it. The gel container made of the woven or nonwoven bamboo fiber fabric has a density of 0.15 to 0.25 mg / mm 3 According to the results of an experiment conducted on an electrically heated smoking article including a gel aerosol generating substrate cartridge corresponding to 100 mg of the liquid composition, the liquid composition was maintained absorbed in the gel container without any problem of leakage to the outside during the experiment, and a much more abundant aerosol was confirmed than in existing heated tobacco products, and sufficient aerosol derived from a larger amount of the liquid composition was confirmed than in existing hybrid types or when the liquid composition was absorbed.

[0061] According to a preferred embodiment, the wrapping paper 61 forming the gel aerosol-generating substrate cartridge 56 may be provided as a laminate formed by attaching aluminum foil to paper, and the aluminum foil is wrapped in a cylindrical shape so as to contact the gel container 56a. As a result, the aluminum foil can prevent or minimize the possibility that the gel aerosol-generating substrate in a liquid state contained in the gel container 56a will flow out through the side of the gel aerosol-generating substrate cartridge 56. That is, as can be seen from the configuration of the gel aerosol-generating substrate cartridge shown in Figures 1 and 2, the gel container 56a is wrapped in a separate wrapping paper 61 before being wrapped in the wrapping paper 60 for forming a smoking article, and at this time, it is preferable that the wrapping paper 61 be provided in a form in which the aluminum foil is attached to paper, and the aluminum foil is wrapped in a cylindrical shape so as to contact the gel container 56a.

[0062] The tobacco body 58 can include solid materials based on tobacco raw materials such as tabular tobacco, cut tobacco, and reconstituted tobacco. In one embodiment, the tobacco body 58 can be filled with a crinkled tabular sheet. The tabular sheet can be crinkled by rolling, folding, compressing, or shrinking substantially transversely to the cylinder axis. The porosity can be determined by adjusting the spacing of the valleys of the crinkled tabular sheet, etc.

[0063] In another embodiment, the tobacco body 58 can be filled with tobacco shreds or the like, which can be produced by shredding a tobacco sheet (or a slurry sheet). The tobacco body 58 can also be formed by combining multiple tobacco strands in the same direction (parallel) or randomly. Specifically, the tobacco body 58 can be formed by combining multiple tobacco strands to form multiple longitudinal channels through which the aerosol can pass. In this case, the longitudinal channels can be uniform or non-uniform depending on the size and arrangement of the tobacco strands.

[0064] The tobacco body 58 may further include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco body may also further include glycerin and propylene glycol.

[0065] The tobacco body 58 may also contain other additives such as flavoring agents and / or organic acids. For example, the flavoring agents 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, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang-ylang, sage, spearmint, ginger, coriander, or coffee. Meanwhile, the tobacco medium-containing portions 11a and 11b may also partially contain glycerin or propylene glycol.

[0066] In some cases, the liquid composition contains nicotine without a tobacco body made of tobacco shredded leaves, and an electrically heated smoking article can be produced by sequentially stacking a tube and a filter on a gel aerosol-generating substrate cartridge and wrapping it with wrapping paper.

[0067] The electrically heated smoking article 50 according to the present invention may include a paper tube 54 that provides a passageway for the aerosol to travel, as shown in Figures 1 and 2, and may also have PLA inserted into it to reduce the temperature of the aerosol and prevent the user from being burned when inhaling the aerosol. The paper tube 54 may also be wrapped in a separate wrapping paper (not shown). In this case, the wrapping paper for the paper tube 54 may be paper, i.e., paper.

[0068] As shown in Figs. 1 and 2, the filter 52, which serves as a mouthpiece, allows aerosol to pass through and prevents liquid from entering. As described above, the gel-type aerosol-generating substrate maintained in the gel container 56a is maintained in the gel container 56a in a gel state in a first temperature range including room temperature. However, in an abnormal environment such as when the surrounding environment in which the smoking article is stored reaches a second temperature range or when excessive external force acts only on the gel-type aerosol-generating substrate cartridge 56 in that situation, some of the liquid composition may leak out. In this case, the filter serves to prevent the liquid from entering (a paper tube also functions in a similar manner). The filter may be made of pulp and may be manufactured in a cylindrical or tubular shape. Meanwhile, the filter may contain a flavoring agent to improve the user's satisfaction. Flavoring agents can include, for example, 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, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang-ylang, sage, spearmint, ginger, coriander, or coffee.

[0069] Essentially, the above-mentioned gel aerosol generating substrate cartridge 56 is manufactured by using the same process and equipment as that used for impregnating the filter 52 with a flavoring agent as described above. Since the existing process and equipment are used as is, there is no difficulty in satisfying mass production and quality control.

[0070] The electrically heated smoking article 50 is usually wrapped with multiple layers of wrapping paper 60, 61, 62, but can be wrapped with multiple layers of wrapping paper such as a first wrapping paper 61 wrapping the portion where the gel aerosol-generating substrate cartridge is located, a second wrapping paper 62 wrapping both the gel aerosol-generating substrate cartridge and the tobacco body made of tobacco shreds downstream or upstream of the first wrapping paper 61, a third wrapping paper (not shown) wrapping the tube thereon, and a fourth wrapping paper 60 wrapping all the portions of the electrically heated smoking article thereon. In this way, an electrically heated smoking article is obtained by wrapping in various stages, but depending on the case, the process of forming the gel aerosol-generating substrate cartridge may be performed separately or through a continuous line.

[0071] Alternatively, in order to shorten the manufacturing time and reduce the manufacturing costs, wrapping materials of different materials or thicknesses may be layered and wrapped at once inside the wrapping paper located at the outermost periphery that wraps all parts of the electrically heated smoking article.

[0072] 1 and 2, a gel aerosol-generating substrate cartridge 56 according to one embodiment of the present invention has a gel container 56a, in which a gel aerosol-generating substrate containing a liquid composition is accommodated, wrapped in wrapping paper 61 acting as a housing. A paper tube 54 and a filter 52 are installed in sequence at the downstream end of the gel aerosol-generating substrate cartridge 56. The filter and the tube are wrapped in wrapping paper 60 together with the gel aerosol-generating substrate cartridge.

[0073] The gel aerosol-generating substrate in the gel aerosol-generating substrate cartridge 56 is maintained in a gel state in a gel container within the gel aerosol-generating substrate cartridge 56 within a first temperature range, and the liquid composition contained in the gel aerosol-generating substrate does not flow out of the gel aerosol-generating substrate cartridge 56 but is vaporized by heating to generate an aerosol.

[0074] The wrapping papers 60, 61, 62 are preferably made of a material that is not deformed by contact with high heat or liquid, or does not generate substances harmful to the human body. Alternatively, the wrapping paper can be made of a metal thin film or metal foil, and as described above, the wrapping paper made of paper can be in the form of a metal thin film or metal sheet superimposed or laminated. According to a preferred embodiment of the present invention, the wrapping paper 61 serving as a housing for the gel aerosol-generating substrate cartridge 56 is made of a laminate of paper and aluminum foil, and the aluminum foil abuts against the gel container 56a, and the gel container 56a is placed in the second temperature range during the manufacturing process or storage, thereby preventing the gel aerosol-generating substrate from changing to a liquid state and flowing out to the side of the gel aerosol-generating substrate cartridge 56.

[0075] The filter 52 provided downstream of the gel aerosol generating substrate cartridge has a hollow portion for forming an airflow, but a filter having no hollow portion may also be used. The filter is composed of at least one segment, and may include at least one of a tube filter, a cooling structure, and a recess filter. The tube filter has a hollow portion inside. The tube filter and the recess filter are made of cellulose acetate, and the tube acting as the cooling structure may be made of pure polylactic acid or a combination of different degradable polymers and polylactic acid.

[0076] More specifically, the filter 52 can be made of materials such as acetate, paper, and PP, and the filter wrapping paper that wraps the filter can be classified into general paper, porous paper, perforated paper, and NWA (Non Wrapped Acetate). The filter can be classified into a mono-filter consisting of one segment and a composite (double, triple, etc.) filter consisting of multiple segments. The filter can be made of acetate tow, plasticizer, activated carbon, X-DNA, and wrapping paper. Acetate tow is an aggregate of continuous cellulose acetate filaments, and plays a crucial role in determining the suction resistance, which is the most important characteristic of the filter. The properties of acetate tow are determined by the density.

[0077] Plasticizers make cellulose acetate fibers soft and pliable, forming bonds at the contact points between the fibers and making the fiber bundles more rigid. Triacetin is used as a plasticizer for cigarette filters.

[0078] Activated carbon, which is one type of adsorbent, is a substance whose main component is carbon and can be classified according to particle size and properties. The raw materials used for activated carbon include plant-based raw materials such as wood, wood powder, and fruit shells (coconut shells, bamboo, and peach seeds).

[0079] X-DNA is a functional particle that is extracted from seaweed and then concentrated. Compared to activated carbon, which is mainly used in cigarette filters, it does not affect the taste of cigarettes and has excellent removal function of various carcinogens.

[0080] The function of wrapping paper is to maintain the shape of the filter floc during filter production. When wrapping paper is produced, it must satisfy certain physical properties such as porosity, tensile strength, elongation, thickness, and adhesion.

[0081] For example, the length of the gel aerosol-generating substrate cartridge 56 may be 14.0 mm, the length of the filter 52 or the tube 54 may each be 2.5 mm, and the length of the tobacco body 58 containing the tobacco shreds may be 9.0 mm. Alternatively, as an example, the filter 52 may be 10 mm, the paper tube 54 may be 16 mm, the gel aerosol-generating substrate cartridge 56 may be 10 mm, and the tobacco body 58 may be 12 mm.

[0082] The relative lengths of the filter 52, the paper tube 54, the gel aerosol-generating substrate cartridge 56, and the tobacco body 58, and the relative arrangement of the gel aerosol-generating substrate cartridge 56 and the tobacco body 58 are related to the temperature of the aerosol in the process of the user inhaling the aerosol generated in the electrically heated smoking article by the aerosol generating device 100 described later. Since the temperature of the aerosol generated in the gel aerosol-generating substrate cartridge 56 is different from that of the aerosol generated in the tobacco body 58, and the high-temperature aerosol can be further cooled by increasing the length of the paper tube 54, the relative lengths and arrangements of these can be changed based on the amount of the liquid composition and the tobacco leaves, which depend on the volume of the gel aerosol-generating substrate cartridge 56 and the tobacco body 58, and the heating method of the aerosol generating device described later, in consideration of the temperature of the aerosol generated in the gel aerosol-generating substrate cartridge 56 and the tobacco body 58, and the relative arrangement of the gel aerosol-generating substrate cartridge 56 and the tobacco body 58. It would not be difficult for a person having ordinary skill in the art to which the present invention pertains to manufacture an electrically heated smoking article of a similar size to currently commercially available electrically heated smoking articles while satisfying the above-mentioned various conditions.

[0083] As described above, according to a preferred embodiment for manufacturing the gel aerosol-generating substrate cartridge 56 shown in Fig. 3, first, the gel aerosol-generating substrate is heated in the second temperature range to be liquidized, and then the gel container 56a formed in a cylindrical shape by the pipe structure 40 passes through a liquid injecting portion such as a spray device or a needle before being introduced into the pipe structure 40, and the liquid is sufficiently sprayed or injected into the gel container 56a, and the gel container 56a contains the liquid or becomes hygroscopic with the liquid while passing through the pipe structure 40. Thereafter, the gel container that has absorbed the liquid is wrapped with wrapping paper made of, for example, paper (or paper laminated with aluminum foil) and cut to a required length (for example, 140 mm, 100 mm, or 80 mm) to form a gel container rod 57. As described below, the gel containing body rod 57 is cut into a gel aerosol-generating substrate cartridge 56 of a desired length (for example, 14 mm, 10 mm, or 8 mm), and then packed (wrapped) together with other electrically heated smoking article segments (tubes, filters, and tobacco bodies) to manufacture an electrically heated smoking article for aerosol generation 50. As described above, the liquid introduced into the gel containing body 56a gels while being maintained in the first temperature range when passing through the pipe structure 40, when being stored after being cut into the gel containing body rod 57, or when being stored after being cut into the gel aerosol-generating substrate cartridge 56, and is present in the form of fine particles dispersed on the surface, pores, and network within the gel containing body 56a.

[0084] 4 is a schematic diagram showing a cutting process for cutting a gel containing rod 57 to manufacture a gel aerosol generating substrate cartridge 56 according to another preferred embodiment of the present invention. As described above, the gel containing rod 57 having a length of, for example, 140 mm, 100 mm, or 80 mm is introduced into the groove of the index table 70 and moved to the conveyor belt 90 by the rotation of the index table. At this time, a rotary blade 80 is disposed on the path along which the gel containing rod 57 moves along the index table 70, and the rotary blade cuts the gel containing rod 57 into ten gel aerosol generating substrate cartridges 56 having a desired length, for example, lengths of 14 mm, 10 mm, and 80 mm. There are ten rotating blades 80 arranged at equal intervals, and they can cut a 140 mm gel containing body rod 57 into ten 14 mm gel aerosol generating substrate cartridges 56, a 100 mm gel containing body rod 57 into ten 10 mm gel aerosol generating substrate cartridges 56, or an 80 mm gel containing body rod 57 into ten 8 mm gel aerosol generating substrate cartridges 56. As described above, the above process and equipment are the same as those applied when adding flavorings to filters in the existing cigarette manufacturing, and therefore there is no difficulty in satisfying mass productivity and quality control as is.

[0085] According to a preferred embodiment of the present invention, a filter 52 serving as a mouthpiece is located at the downstream end of a gel aerosol-generating substrate cartridge 56, and a tobacco body 58 containing tobacco shreds is located at the upstream end of the gel aerosol-generating substrate cartridge 56. These segments (filter, gel aerosol-generating substrate cartridge, tobacco body) are packed together to produce an electrically heated smoking article for aerosol generation. As described above, a tube 54 providing a passage for aerosol movement can be located between the filter 52 and the gel aerosol-generating substrate cartridge 56 as necessary. These segments, i.e., the filter, tube, liquid cartridge, and tobacco body, are arranged in a line and packed together to obtain an electrically heated smoking article for aerosol generation 50. In an actual production line, these are lined up in a set of 10 or more, and can be cut into a large number of electrically heated smoking articles after wrapping.

[0086] In any case, the liquid composition, which is the aerosol-generating substrate contained in the gel aerosol-generating substrate cartridge 56, is gelled and dispersed in the form of fine particles on the surface, pores, network, etc. of the gel container in the gel aerosol-generating substrate cartridge, and even if it is liquefied, it is absorbed by the gel container 56a, so it does not flow out of the gel aerosol-generating substrate cartridge, but it is possible to consider the case where the liquid composition flows out or vaporizes into an aerosol and flows out due to high temperature or physical pressure applied to the gel aerosol-generating substrate cartridge during the process of manufacturing the electrically heated smoking article or after the electrically heated smoking article is completed. First, according to a preferred embodiment of the present invention, a cigarette body is located upstream of the gel aerosol-generating substrate cartridge, and a filter is located downstream of the gel aerosol-generating substrate cartridge, so that even if high temperature or physical pressure is applied to the gel aerosol-generating substrate cartridge from the outside, the liquid composition is unlikely to flow out through the filter or cigarette body to the outside. Since the gel aerosol-generating substrate liquefies in a second temperature range including 70° C. and the liquid composition starts to generate an aerosol at or above about 120° C., loss of the liquid composition during the manufacturing process can be prevented by controlling the process in the wrapping or manufacturing process of the gel aerosol-generating substrate cartridge within a first temperature range of 100° C. or less, preferably less than 50° C. If a high temperature equal to or higher than the vaporization temperature of the liquid composition is unavoidably required during the manufacturing process, the amount of liquid composition that may be lost during the process can be estimated, and the expected amount of loss can be added to the required amount, and the liquid composition can be further controlled by absorbing moisture.

[0087] Hereinafter, an embodiment of an aerosol generating device 100 capable of generating an aerosol by heating an electrically heated smoking article 50 according to the present invention will be described. The aerosol generating device 100 described below is an aerosol generating device of a size that can be held and carried, which has a cavity into which an electrically heated smoking article 50, which contains an aerosol-forming substrate such as a liquid composition or tobacco leaves in a smoking article and is wrapped in wrapping paper in the form of an existing cigarette, can be inserted, and which heats the aerosol-forming substrate of the smoking article inserted into the cavity with a heater provided in the aerosol generating device to form an aerosol, as described later. The heater can be provided by a resistance heating method or an induction heating method, as will be described later, and is heated to a temperature of 100 to 400° C., for example, to heat the aerosol-forming substrate provided in the electrically heated smoking article 50 inserted into the cavity of the aerosol generating device to generate an aerosol. According to a preferred example, the target temperature may be in the range of 200 to 350°C, and according to a more preferred example, the target temperature may be in the range of 250 to 320°C (for example, 280°C is the target temperature). In some cases, the target temperature may be in the range of 150 to 250°C (for example, 180°C is the target temperature), but this may vary depending on whether the object from which the aerosol is to be generated is a liquid composition (glycerin, etc.), a tobacco body, or a tobacco body in which a liquid composition such as glycerin has been absorbed. In any case, since the aerosol generated in the electrically heated smoking article 50 is inhaled into the user's mouth through the tube 54 and the filter 52, even if it is cooled during the inhalation process, if the temperature of the generated aerosol becomes too high, the user may feel uncomfortable or may be burned, and it may be difficult to puff several times due to the generation of excessive aerosol, so the target temperature of the heating element must be determined in advance taking these points into consideration. Also, for the reasons mentioned above, the upper limit of the target temperature of the heating element is limited as described above.

[0088] According to a preferred embodiment, the temperature of the generated aerosol exiting through tube 54 and filter 52 can be measured as the mouth end temperature, and in order to avoid discomfort to the user, the temperature of the aerosol should be less than 50° C., and preferably less than 45° C. The preferred aerosol mouth end temperature is in the range of 25 to 45° C., and more preferably in the range of 30 to 40° C.

[0089] The aerosol generating device 100 includes a rechargeable battery 110 provided in the device and serving as a DC power source, and a control unit 120 for controlling the output from the battery 110. In FIG. 5, a conceptual diagram of such an aerosol generating device 100 is shown together with an electrically heated smoking article 50, and is shown in a schematic cross-sectional view for the purpose of explaining the heating method in each embodiment. For convenience of explanation, the electrically heated smoking article 50, which is a smoking article, will be described based on a configuration in which a filter 52, a tube 54, a gel aerosol-generating substrate cartridge 56, and a tobacco body 58 are arranged in this order and wrapped in wrapping paper 60. As already explained, in each case, the relative positions of the gel aerosol-generating substrate cartridge 56 and the tobacco body 58 may be changed relative to each other.

[0090] In addition, the following description is provided for illustrative purposes only, and the scope of the present invention is not limited thereto. A person having ordinary skill in the art to which the present invention pertains should easily understand that an aerosol generating system falling within the scope of the present invention can be constructed by deleting or adding parts from the configuration of the aerosol generating device exemplified below, or by combining it with other devices.

[0091] As described above, FIG. 5 is a schematic diagram of an example of an aerosol generating system to which the present invention can be applied, and is also a schematic cross-sectional view of an aerosol generating device 100 according to a first embodiment of the present invention.

[0092] The aerosol generating system includes an aerosol generating device 100 and an electrically heated smoking article 50. Here, the electrically heated smoking article 50, which is a smoking article, is configured by wrapping a filter 52, a paper tube 54, a gel aerosol-generating substrate cartridge 56, and a tobacco body 58 in wrapping paper 60, as described above, and is inserted into a hollow space provided in the aerosol generating device 100.

[0093] The aerosol generating device 100 includes an electric resistance pipe heater 130b for heating the liquid composition absorbed in the gel aerosol generating substrate cartridge 56 to generate an aerosol, and an electric resistance immersion heater 130a for heating the tobacco leaves of the tobacco body 58 to generate an aerosol. In addition, the device includes a battery 110 for supplying power to the heaters 130a, 130b, and a control unit 120 configured to control the power supply from the battery 110 to the heaters 130a, 130b.

[0094] The invasive heater 130a according to the first embodiment described above may be in the shape of a blade with a heater pattern printed on the outside, or in the shape of a rod. In any case, a temperature sensor pattern is provided together with the heater pattern, so that the temperature on the surface of the invasive heater 130a is sensed, and the power supply to the invasive heater 130a can be controlled according to the sensed value. When the invasive heater is inserted into the tobacco body 58 to heat the tobacco body 58 and form an aerosol in the tobacco body 58 as in the first embodiment, the contact with the tobacco body 58 is heated, which helps to generate an aerosol immediately. As described above, the gel aerosol generating substrate cartridge 56 is formed by folding or rolling materials that are physically connected to each other, so that the invasive heater 130a may not be inserted correctly, or even if inserted, the gel container may not be separated correctly when it is removed. Therefore, it is preferable that the invasive heater 130a is inserted only into the tobacco body 58.

[0095] The pipe heater 130b according to the first embodiment described above is also a pipe on which a heater wire or a planar heating element pattern is printed or provided on the outside. Like the immersive heater 130a, the pipe heater 130b is also provided with a temperature sensor pattern to sense the temperature, and power supply to the pipe heater 130b is controlled based on the sensed value. The pipe heater 130b heats the gel aerosol-generating substrate cartridge 56 of the electrically heated smoking article 50 at the side of the gel aerosol-generating substrate cartridge 56, thereby heating the aerosol-generating substrate present in a gel state within the gel aerosol-generating substrate cartridge to generate aerosol.

[0096] The heater heats the aerosol-generating substrate to a temperature range of 150-350°C to generate an aerosol, and the aerosol generated by the user's inhalation is inhaled through the user's mouth via the paper tube 54 and the filter 52. As an example, the immersion heater 130a heats the tobacco shreds of the tobacco body 58 to a temperature range of 150-250°C to generate an aerosol derived from the tobacco shreds, and the pipe heater 130b heats the gel container of the gel aerosol-generating substrate cartridge 56 to a temperature range of 250-350°C to generate an aerosol derived from the liquid composition of the gel container. The temperature conditions may be opposite to each other. Even when heated in the above temperature range, the wrapping paper does not burn, and a part of the wrapping paper may be burned.

[0097] Of course, the heater patterns of the heaters 130a and 130b, the sensing unit and the control unit are electrically connected to each other, and the battery and the control unit are also electrically connected to each other.

[0098] FIG. 6 shows a schematic cross-section of an aerosol generating system according to a second embodiment of the present invention.

[0099] The configuration of the electrically heated smoking article 50 is similar to that of the first embodiment.

[0100] The aerosol generating device 100 according to the second embodiment has one resistance heating type pipe heater 132 corresponding to the gel aerosol generating substrate cartridge 56 and the tobacco body 58. Like the pipe heater 130b according to the first embodiment described above, it is a pipe on which a heater wire or a planar heating element pattern is printed or provided on the outside. The pipe heater 132 according to the second embodiment is also provided with a temperature sensor pattern to sense the temperature, and power supply to the pipe heater 132 can be controlled according to the sensed value. The pipe heater 132 not only heats the gel aerosol generating substrate cartridge 56 of the electrically heated smoking article 50 at the side of the gel aerosol generating substrate cartridge 56 to generate aerosol from the aerosol generating substrate present in a gel state in the gel aerosol generating substrate cartridge, but also heats the tobacco body 58 of the electrically heated smoking article 50 at the side of the tobacco body 58 to generate aerosol from tobacco shreds provided in the tobacco body 58. The pipe heater 132 of the second embodiment heats the gel aerosol-generating substrate cartridge 56 and the tobacco body 58 at essentially the same temperature. The target temperature can be in the range of 150 to 350°C, and the temperature can be adjusted by the temperature sensing value. Even if heated in the above temperature range, the wrapping paper does not burn, and part of the wrapping paper may be burned.

[0101] For electrically heated smoking articles to be used in such devices, the amount of aerosol generated from the liquid composition and the amount of aerosol generated from the tobacco shreds can be appropriately adjusted by adjusting the relative positions of the gel aerosol-generating substrate cartridge 56 and the tobacco body 58, or by adjusting their relative volumes (or heights).

[0102] Of course, the heater pattern of the pipe heater 132, the sensing unit and the control unit 120 are electrically connected to each other, and the battery and the control unit are also electrically connected to each other. It is preferable that the pipe heater 132 surrounds only the gel aerosol generating substrate cartridge 56 and the tobacco body 58, and does not surround the paper tube 54 or the filter 52.

[0103] FIG. 7 shows a schematic cross-section of an aerosol generation system according to a third embodiment of the present invention.

[0104] The configuration of the electrically heated smoking article 50 is similar to that of the above-described embodiment.

[0105] The aerosol generating device 100 according to the third embodiment has a resistance heating type pipe heater 132a corresponding to the gel aerosol generating substrate cartridge 56, and a resistance heating type pipe heater 132b corresponding to the tobacco body 58. Like the pipe heaters according to the previous embodiments, they are pipes on which a heater wire or a planar heating element pattern is printed or provided on the outside. The pipe heaters 132a and 132b according to the third embodiment are also provided with a temperature sensor pattern to sense the temperature, and power supply to the pipe heaters 132a and 132b can be controlled based on the sensed value. The pipe heater 132a heats the gel aerosol-generating substrate cartridge 56 at the side of the gel aerosol-generating substrate cartridge 56 of the electrically heated smoking article 50 to generate an aerosol from the aerosol-generating substrate present in a gel state in the gel aerosol-generating substrate cartridge, and the pipe heater 132b heats the tobacco body 58 at the side of the tobacco body 58 of the electrically heated smoking article 50 to generate an aerosol from the tobacco leaves and the like provided in the tobacco body 58. The pipe heaters 132a and 132b of the third embodiment can heat the gel aerosol-generating substrate cartridge 56 and the tobacco body 58 at different temperatures. The target temperature can be in the range of 150 to 350°C, and the temperature can be adjusted according to the temperature sensing value. The generated aerosol is inhaled through the user's mouth via the paper tube 54 and the filter 52 when the user inhales. As an example, the pipe heater 132b can heat the tobacco shreds of the tobacco body 58 in a temperature range of 150 to 250°C to generate an aerosol derived from the tobacco shreds, and the pipe heater 132a can heat the gel container of the gel aerosol generating substrate cartridge 56 in a temperature range of 250 to 350°C to generate an aerosol derived from the liquid composition of the gel container. The above temperature conditions can be opposite to each other. Even when heated in the above temperature range, the wrapping paper does not burn, and a part of the wrapping paper may be burned.

[0106] When the configuration of the third embodiment is adopted, there are no problems associated with immersion type heaters (problems of residues generated from the electrically heated smoking article after use and problems of not being easily inserted into the gel aerosol-generating substrate cartridge), and in electrically heated smoking articles having the configuration shown in the figures, as well as in electrically heated smoking articles in which the relative positions of the gel aerosol-generating substrate cartridge 56 and the tobacco body 58 have been changed, it becomes possible to appropriately generate aerosol from the gel aerosol-generating substrate cartridge 56 and the tobacco body 58, while at the same time setting and controlling the temperature of the pipe heaters 132a, 132b to match the optimal aerosol-generating temperature of each aerosol-forming substrate.

[0107] Of course, the heater patterns of the pipe heaters 132a, 132b, the sensing unit and the control unit 120 are electrically connected to each other, and the battery and the control unit are also electrically connected to each other. It is preferable that the pipe heaters 132a, 132b surround only the gel aerosol generating substrate cartridge 56 and the tobacco body 58, and not the paper tube 54 or the filter 52.

[0108] FIG. 8 shows a schematic cross-section of an aerosol generation system according to a fourth embodiment of the present invention.

[0109] The configuration of the electrically heated smoking article 50 is similar to that of the above-described embodiment.

[0110] The aerosol generating device 100 according to the fourth embodiment has one resistance heating type pipe heater 134b having a height corresponding to the gel aerosol generating substrate cartridge 56 and the tobacco body 58, and an immersion type heater 134a that can be inserted into the tobacco body 58.

[0111] The pipe heater 134b is provided with a heater wire or a sheet-shaped heating element pattern printed or provided on the outside, as in the above-mentioned pipe heater, and is also provided with a temperature sensor pattern to sense the temperature, and the power supply to the pipe heater 134b can be controlled based on the sensed value. The pipe heater 134b not only heats the gel aerosol-generating substrate cartridge 56 of the electrically heated smoking article 50 at the side of the gel aerosol-generating substrate cartridge 56 to generate aerosol from the aerosol-generating substrate present in a gel state in the gel aerosol-generating substrate cartridge, but also heats the tobacco body 58 of the electrically heated smoking article 50 at the side of the tobacco body 58 to generate aerosol from tobacco shreds and the like provided in the tobacco body 58. The pipe heater 134b of the fourth embodiment also heats the gel aerosol-generating substrate cartridge 56 and the tobacco body 58 at essentially the same temperature. However, unlike the second embodiment, the fourth embodiment further provides an immersion heater 134a having the above-mentioned configuration that can be inserted into the tobacco body 58. This configuration means that an additional heating source can be provided for the tobacco body 58, so that it can more effectively accommodate the aerosol-generating substrate provided in the electrically heated smoking article. In any case, the target temperature can be in the temperature range of 150 to 350°C, and the temperature can be adjusted according to the temperature sensing value. As an example, the pipe heater 134b can heat the aerosol-generating substrate present in a gel state in the gel container of the gel-type aerosol-generating substrate cartridge 56 and the tobacco shreds of the tobacco body 58 in a temperature range of 150 to 250°C to generate an aerosol derived therefrom, and further, the immersion heater 134a can heat the tobacco shreds of the tobacco body 58 in a temperature range of 250 to 350°C to generate an aerosol derived from the tobacco shreds. The above temperature conditions can be opposite to each other. Even when heated in the above temperature range, the wrapping paper does not burn, and a part of the wrapping paper can be burned.

[0112] Of course, the heater patterns, sensing unit and control unit 120 of the invasive heater 134a and the pipe heater 134b are electrically connected to each other, and the battery and control unit are also electrically connected. It is preferable that the pipe heater 134b surrounds only the gel aerosol generating substrate cartridge 56 and the tobacco body 58, and does not surround the paper tube 54 or the filter 52. It is preferable that the invasive heater 134a is inserted only into the tobacco body 58 for the reasons mentioned above.

[0113] 9 to 12 are examples of an aerosol generating system using an induction heating heater. Electrical equipment used for induction heating includes, as induction heating components, excitation coils 136a, 136c, 138b, 140a, and 140b that are cylindrical and wound several times, and susceptors (magnetized heating elements) that react with the excitation coils 136a, 136c, 138b, 140a, and 140b and are induction heated by eddy current loss. Here, the susceptor is a hollow cylindrical thin plate provided within the excitation coils 136a, 136c, 138b, 140a, 140b so as to be surrounded by the excitation coils 136a, 136c, 138b, 140a, 140b within the device, and defines a cavity into which an electrically heated smoking article 50, which is a smoking article, can be inserted.The susceptor is a heat pipe 136, 136d, 138a, 142a, 142b made of a metal material that reacts with the excitation coils 136a, 136c, 138b, 140a, 140b and is heated to a temperature of 400°C or less by induction heating due to eddy current loss. Depending on the magnitude of the AC current applied to the excitation coils 136a, 136c, 138b, 140a, 140b, the temperature of the susceptor can be heated to a temperature of 1000° C. or more, but in the present invention, the susceptor acting as a heating element is heated to a temperature of 400° C. or less as described above. The temperature of the heat pipes 136, 136d, 138a, 142a, 142b is sensed by a temperature sensor that physically contacts the surface of the heat pipes 136, 136d, 138a, 142a, 142b, or the temperature of the susceptor can be calculated from the change in current and voltage from a current sensor and a voltage sensor that measure the change in current and voltage that heats the susceptor due to the value of inductance or reactance that changes with the temperature change of the susceptor acting as the heat pipes 136, 136d, 138a, 142a, 142b.

[0114] For induction heating, the control unit receives DC power from the battery 110 and supplies AC current of the resonant frequency or an AC current of a frequency different from the resonant frequency to the excitation coil. The control unit controls the AC current applied to the excitation coil according to temperature changes of the susceptor, thereby making it possible to heat, maintain, or change the susceptor at a desired temperature.

[0115] FIG. 9 shows a schematic cross-section of an aerosol generation system according to a fifth embodiment of the present invention.

[0116] The configuration of the electrically heated smoking article 50 is similar to that of the above-described embodiment.

[0117] The aerosol generating device 100 according to the fifth embodiment has a heat pipe 136 of an induction heating type corresponding to the gel aerosol-generating substrate cartridge and a hitting blade 136b of an induction heating type corresponding to the tobacco body 58. The heat pipe 136 and the hitting blade 136b are all made of susceptors and are heated by induction heating. The heat pipe 136 heats the gel aerosol-generating substrate cartridge 56 of the electrically heated smoking article 50 at the side of the gel aerosol-generating substrate cartridge 56 to generate aerosol from the aerosol-generating substrate present in a gel state in the gel aerosol-generating substrate cartridge, and the hitting blade 136b heats the tobacco leaves and the like in the tobacco body 58 of the electrically heated smoking article 50 to generate aerosol.

[0118] The heat pipe 136 and the hit blade 136b acting as a susceptor are provided separately from each other, so that it is possible to achieve a desired heating temperature condition by adjusting the material and thickness thereof.

[0119] The temperature conditions controlled may be the same or similar to those described above. That is, the heat pipe 136 and the hit blade 136b of the fifth embodiment may heat the gel aerosol generating substrate cartridge 56 and the tobacco body 58 at different temperatures. The target temperature may be in the range of 150 to 300°C, and the temperature may be adjusted according to the temperature sensing value, and the generated aerosol is inhaled through the user's mouth via the paper tube 54 and the filter 52 by the user's inhalation. As an example, the hit blade 136b may heat the tobacco shreds of the tobacco body 58 at a temperature range of 150 to 200°C to generate an aerosol derived from the tobacco shreds, and the heat pipe 136 may heat the gel container of the gel aerosol generating substrate cartridge 56 at a temperature range of 250 to 300°C to generate an aerosol derived from the liquid composition of the gel container. The temperature conditions may be opposite to each other. Even when heated in the above temperature range, the wrapping paper may not burn, and a part of the wrapping paper may be burned.

[0120] Of course, the exciting coil 136a, the sensing unit and the control unit 120 are electrically connected to each other, and the battery and the control unit are also electrically connected, and it is preferable that the heat pipe 136 surrounds only the gel aerosol generating substrate cartridge 56, and does not surround the paper tube 54 or the filter 52. Also, it is preferable that the hitting blade 136b is inserted only up to the tobacco body 58, like an electric resistance type immersion heater.

[0121] FIG. 10 shows a schematic cross-section of an aerosol generating system according to a sixth embodiment of the present invention.

[0122] The configuration of the electrically heated smoking article 50 is similar to that of the above-described embodiment.

[0123] The aerosol generating device 100 according to the sixth embodiment is an example in which a heat pipe 136d of an induction heating type corresponding to a gel aerosol generating substrate cartridge and a pipe heater 136e of a resistance heating type corresponding to a tobacco body 58 are combined.

[0124] The heat pipe 136d, acting as a susceptor, heats the gel aerosol-generating substrate cartridge 56 on the side of the gel aerosol-generating substrate cartridge 56 of the electrically heated smoking article 50, thereby generating aerosol from the aerosol-generating substrate present in gel form within the gel aerosol-generating substrate cartridge.

[0125] In addition, the pipe heater 136e that uses resistance heating heats the tobacco body 58 at the side of the tobacco body 58 of the electrically heated smoking article 50, causing the tobacco shreds and the like within the tobacco body 58 to generate an aerosol.

[0126] For electrically heated smoking articles to be used in such devices, the amount of aerosol generated from the liquid composition and the amount of aerosol generated from the tobacco shreds can be appropriately adjusted by adjusting the relative positions of the gel aerosol-generating substrate cartridge 56 and the tobacco body 58, or by adjusting their relative volumes (or heights).

[0127] The heat pipe 136d and the pipe heater 136e of the sixth embodiment can heat the gel aerosol generating substrate cartridge 56 and the tobacco body 58 at different temperatures. The target temperature can be in the range of 150 to 350°C, and the temperature can be adjusted according to the temperature sensing value. The generated aerosol is inhaled through the user's mouth via the paper tube 54 and the filter 52 by the user's inhalation. As an example, the hit blade 136b can heat the tobacco shreds of the tobacco body 58 at a temperature range of 150 to 250°C to generate an aerosol derived from the tobacco shreds, and the heat pipe 136d can heat the gel container of the gel aerosol generating substrate cartridge 56 at a temperature range of 250 to 350°C to generate an aerosol derived from the liquid composition of the gel container. The above temperature conditions can be opposite to each other. Even when heated in the above temperature range, the wrapping paper does not burn, and a part of the wrapping paper can be burned.

[0128] Of course, the excitation coil 136c, the heater pattern of the pipe heater 136e, the sensing unit and the control unit 120 are all electrically connected to each other, and the battery and the control unit are also electrically connected to each other. It is preferable that the heat pipe 136d and the pipe heater 136e surround only the gel aerosol generating substrate cartridge 56 and the tobacco body 58, and not surround the paper tube 54 or the filter 52.

[0129] FIG. 11 shows a schematic cross-section of an aerosol generation system according to a seventh embodiment of the present invention.

[0130] The configuration of the electrically heated smoking article 50 is similar to that of the above-described embodiment.

[0131] The aerosol generating device 100 according to the seventh embodiment shows a system in which the gel aerosol generating substrate cartridge 56 and the tobacco body 58 are entirely heated by the heat pipe 138a of the induction heating system. Not only is an aerosol generated from the aerosol generating substrate present in a gel state in the gel container of the gel aerosol generating substrate cartridge 56 by the heat generated by the heat pipe 138a, but also from the tobacco shreds and the like in the tobacco body 58. The heat pipe 138a of the seventh embodiment heats the gel aerosol generating substrate cartridge 56 and the tobacco body 58 at essentially the same temperature. The target temperature can be in the range of 150 to 350°C, and the temperature can be adjusted by the temperature sensing value. Even if the wrapping paper is heated in the above temperature range, the wrapping paper does not burn, and a part of the wrapping paper can be burned.

[0132] For electrically heated smoking articles to be used in such devices, the amount of aerosol generated from the liquid composition and the amount of aerosol generated from the tobacco shreds can be appropriately adjusted by adjusting the relative positions of the gel aerosol-generating substrate cartridge 56 and the tobacco body 58, or by adjusting their relative volumes (or heights).

[0133] Of course, the excitation coil 138b, the sensing unit and the control unit 120 are electrically connected to each other, and the battery and the control unit are also electrically connected to each other. It is preferable that the heat pipe 138a surrounds only the gel aerosol generating substrate cartridge 56 and the tobacco body 58, and does not surround the paper tube 54 or the filter 52.

The heat pipes 142a and 142b of the eighth embodiment can heat the gel aerosol-generating substrate cartridge 56 and the tobacco body 58 at different temperatures. The target temperature may be in the range of 150 to 350°C, and the temperature may be adjusted according to the temperature sensing value. The generated aerosol is inhaled through the user's mouth via the paper tube 54 and the filter 52 when the user inhales. As an example, the heat pipe 142b may heat the tobacco shreds of the tobacco body 58 in the temperature range of 150 to 250°C to generate an aerosol derived from the tobacco shreds, and the heat pipe 142a may heat the gel container of the gel aerosol generating substrate cartridge 56 in the temperature range of 250 to 350°C to generate an aerosol derived from the liquid composition of the gel container. The temperature conditions may be opposite to each other. Even when heated in the above temperature range, the wrapping paper may not burn, and a part of the wrapping paper may be burned.

It is preferable that the heat pipes 142a, 142b surround only the gel aerosol generating substrate cartridge 56 and the tobacco body 58, and not the paper tube 54 or the filter 52.
