The present disclosure relates to an aerosol-generating article comprising: a first portion comprising an aerosol generating substance; a second portion comprising tobacco material in the form of a tobacco sheet; a third portion configured to cool the airflow that has passed through the first and second portions; and a fourth portion comprising a filtration material, wherein the first portion, the second portion, the third portion and the fourth portion are arranged sequentially in a length direction of the aerosol-generating article.

Description

Aerosol-generating article comprising a tobacco sheet and aerosol-generating system using the aerosol-generating article
Technical Field
The present disclosure relates to aerosol-generating articles comprising a tobacco sheet and aerosol-generating systems using the aerosol-generating articles.
Background
Recently, there has been an increasing demand for alternative methods for aerosol-generating articles in general. For example, there is an increasing demand for aerosol-generating devices that generate an aerosol not by burning an aerosol-generating article, but by heating an aerosol-generating substance in the aerosol-generating article. Therefore, research into heating aerosol-generating products and heating aerosol-generating devices is actively being conducted.
Reconstituted tobacco, including tobacco leaves, tobacco fines, veins, stems, and the like, may be used in the heated aerosol-generating article. Conventionally, reconstituted tobacco in filamentary or cut tobacco form is subjected to a cutting process, whereby the fibrous bonds inside the reconstituted tobacco are broken. Therefore, heat is discontinuously transferred between the tobacco shreds, resulting in heat losses.
Disclosure of Invention
Solution to the problem
Aerosol-generating articles according to embodiments may solve the above-mentioned problems of the prior art.
However, the technical problem is not limited to the above problem, and other technical problems may be inferred from the following examples.
Advantageous effects of the invention
In aerosol-generating articles according to embodiments, heat transfer may be effected within the tobacco sheet as the second portion comprises a continuously extending length of tobacco sheet (tobaco sheet). Thus, with an aerosol-generating article according to the present disclosure, a user may feel an excellent smoking experience.
In addition, in the aerosol-generating article according to the embodiment, since the second portion includes the tobacco material in the form of a rolled sheet instead of a cut tobaco piece, the airflow passage can be stably ensured. As a result, the aerosol-generating article may have a relatively low resistance to inhalation.
The effects of the present disclosure are not limited to the above-described effects, and may include all effects that can be inferred from the configuration described later.

Fig. 1 to 3 are diagrams illustrating an example of an aerosol-generating article 20000 inserted into an aerosol-generating device 10000.
Referring to fig. 1, aerosol-generating device 10000 may include a battery 11000, a controller 12000, and a heater 13000. Referring to fig. 2 and 3, the aerosol-generating device 10000 may further comprise a vaporizer 14000. Furthermore, an aerosol-generating article 20000 may be inserted into the interior space of the aerosol-generating device 10000.
Fig. 1 to 3 show some components of an aerosol-generating device 10000 relevant to the present embodiment. Thus, it will be understood by a person of ordinary skill in the art that other components may be included in the aerosol-generating device 10000 than the components shown in fig. 1 to 3.
Furthermore, fig. 1 to 3 show that the aerosol-generating device 10000 comprises a heater 13000. However, the heater 13000 may be omitted according to embodiments.
Fig. 1 shows a battery 11000, a controller 12000, and a heater 130000 arranged in series. Further, fig. 2 shows that a battery 11000, a controller 12000, a vaporizer 14000, and a heater 13000 are arranged in series. Further, fig. 3 shows a parallel arrangement of the vaporizer 14000 and the heater 13000. However, the internal structure of the aerosol-generating device 10000 is not limited to the structure shown in fig. 1 to 3. In other words, the battery 11000, the controller 12000, the heater 13000, and the vaporizer 14000 may be arranged in different ways depending on the design of the aerosol-generating device 10000.
When the aerosol-generating article 20000 is inserted into the aerosol-generating device 10000, the aerosol-generating device 10000 may operate the heater 13000 and/or the vaporizer 14000 to generate an aerosol from the aerosol-generating article 20000 and/or the vaporizer 14000. The aerosol generated by the heater 13000 and/or the vaporizer 14000 is delivered to the user by passing through the aerosol-generating article 20000.
If desired, the aerosol-generating device 10000 may heat the heater 13000 even when the aerosol-generating article 20000 is not inserted into the aerosol-generating device 10000.
The battery 11000 supplies electric power for operating the aerosol-generating device 10000. For example, the battery 11000 may supply electric power to heat the heater 13000 or the vaporizer 14000, and may supply electric power for operating the controller 12000. Further, the battery 11000 may supply power for operation of a display, a sensor, a motor, and the like installed in the aerosol-generating device 10000.
The controller 12000 may generally control the operation of the aerosol-generating device 10000. In detail, the controller 12000 can control not only the operations of the battery 11000, the heater 13000, and the vaporizer 14000, but also the operations of other components included in the aerosol-generating device 10000. Further, the controller 12000 can check the status of each of the components of the aerosol-generating device 10000 to determine whether the aerosol-generating device 10000 is operable.
The controller 12000 may include at least one processor. The processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. Those of ordinary skill in the art will appreciate that a processor may be implemented in other forms of hardware.
The heater 13000 can be heated by electric power supplied from the battery 11000. For example, the heater 13000 may be located outside the aerosol-generating article 20000 when the aerosol-generating article 20000 is inserted into the aerosol-generating device 10000. Thus, the heated heater 13000 can increase the temperature of the aerosol generating substance in the cigarette 20000.
Heater 13000 can comprise a resistive heater. For example, heater 13000 can include conductive traces, and heater 13000 can be heated when a current flows through the conductive traces. However, the heater 13000 is not limited to the above example, and may include all heaters that can be heated to a desired temperature. Here, the desired temperature may be set in advance in the aerosol-generating device 10000 or may be set to a temperature desired by a user.
As another example, the heater 13000 can comprise an induction heater. In detail, the heater 13000 may comprise an electrically conductive coil for heating the aerosol-generating article in an inductive heating method, and the aerosol-generating article may comprise a base which may be heated by the inductive heater.
For example, the heater 13000 may comprise a tube-type heating element, a plate-type heating element, a needle-type heating element or a rod-type heating element, and may heat the interior or exterior of the aerosol-generating article 20000 depending on the shape of the heating element.
Furthermore, the aerosol-generating device 10000 may comprise a plurality of heaters 13000. Here, the plurality of heaters 13000 may be inserted into the aerosol-generating article 20000 or may be arranged outside the aerosol-generating article 20000. Furthermore, some of the plurality of heaters 13000 may be inserted into the aerosol-generating article 20000 and other heaters may be arranged outside the aerosol-generating article 20000. In addition, the shape of the heater 13000 is not limited to the shape shown in fig. 1 to 3, and may include various shapes.
The vaporizer 14000 can generate an aerosol by heating the liquid composition and the generated aerosol can be delivered to a user through the aerosol-generating article 20000. In other words, the aerosol generated via the vaporizer 14000 can move along an airflow channel of the aerosol-generating device 10000, and the airflow channel can be configured such that the aerosol generated via the vaporizer 14000 is delivered to a user through the cigarette 20000.
For example, vaporizer 14000 can include a liquid storage, a liquid delivery element, and a heating element, but is not limited thereto. For example, the liquid reservoir, the liquid transfer element and the heating element may be comprised in the aerosol-generating device 10000 as separate modules.
The liquid storage portion may store a liquid composition. For example, the liquid composition may be a liquid comprising a tobacco-containing material having a volatile tobacco flavor component, or a liquid comprising a non-tobacco material. The liquid storage portion may be formed to be attached/detached to/from the vaporizer 14000, or may be formed integrally with the vaporizer 14000.
For example, the liquid composition may include water, solvents, ethanol, plant extracts, flavors, fragrances, or vitamin mixtures. Flavors may include, but are not limited to, menthol, peppermint, spearmint, and various fruit flavor components. The scents may include ingredients that provide a variety of scents or tastes to the user. The vitamin mixture may be a mixture of at least one of vitamin a, vitamin B, vitamin C, and vitamin E, but is not limited thereto. In addition, the liquid composition may include aerosol-forming materials such as glycerin and propylene glycol.
The liquid transfer element may transfer the liquid composition of the liquid reservoir to the heating element. For example, the liquid transport element may be a wick, such as, but not limited to, cotton fiber, ceramic fiber, glass fiber, and porous ceramic.
The heating element is an element for heating the liquid composition transferred by the liquid transfer element. For example, the heating element may be a metal heating wire, a metal hot plate, a ceramic heater, or the like, but is not limited thereto. Additionally, the heating element may include a conductive wire, such as a nichrome wire, and may be positioned to wrap around the liquid transport element. The heating element may be heated by the supply of electrical current and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.
For example, vaporizer 14000 may be referred to as a cartomizer or an atomizer, but is not limited thereto.
The aerosol-generating device 10000 may comprise common components in addition to the battery 11000, the controller 12000, the heater 13000, and the vaporizer 14000. For example, the aerosol-generating device 10000 may comprise a display capable of outputting visual information and/or a motor for outputting tactile information. Further, the aerosol-generating device 10000 may comprise at least one sensor (e.g., a puff detection sensor, a temperature detection sensor, a cigarette insertion detection sensor, etc.). Further, the aerosol-generating device 10000 may be formed in a structure in which external air can be introduced or internal air can be discharged even when the cigarette 20000 is inserted into the aerosol-generating device 10000.
Although not shown in fig. 1-3, the aerosol-generating device 10000 and an additional carrier may together form a system. For example, the cradle may be used to charge the battery 11000 of the aerosol-generating device 10000. Alternatively, the heater 13000 may be heated when the carriage and the aerosol-generating device 10000 are coupled to each other.
As an example, external air may be introduced through at least one air channel formed in the aerosol-generating device 10000. For example, the user may adjust the opening and closing of an air passage and/or the size of an air passage formed in the aerosol-generating device 10000. Thus, the quantity and quality of the smoke (e.g., aerosol) may be adjusted by the user. As another example, external air may be introduced into the aerosol-generating article 20000 through at least one aperture formed on a surface of the aerosol-generating article 20000.
Fig. 4 is a view schematically illustrating the configuration of an aerosol-generating article 20000 according to an embodiment.
According to an embodiment, the aerosol-generating article 20000 may comprise a first portion 21000, a second portion 22000, a third portion 23000 and a fourth portion 24000 arranged in series in the length direction of the aerosol-generating article 20000. As an example, the first portion 21000 can include an aerosol generating substance and the second portion 22000 can include a tobacco material. The third portion 23000 can cool the airflow that has passed through the first portion 21000 and the second portion 22000, and the fourth portion 24000 can include a filter material.
In an embodiment, the first portion 21000, the second portion 22000, the third portion 23000 and the fourth portion 24000 may be arranged sequentially in a length direction of the aerosol-generating article 20000. Accordingly, the aerosol generated in at least one of the first portion 21000 and the second portion 22000 can form an airflow sequentially through the first portion 21000, the second portion 22000, the third portion 23000, and the fourth portion 24000. Thus, a user can inhale the aerosol from the fourth portion 24000.
In an embodiment, the first portion 21000 can have a length of about 8mm to about 12mm, and the second portion 22000 can have a length of about 12mm to about 14 mm. However, the embodiment is not necessarily limited thereto, and the lengths of the first portion 21000 and the second portion 22000 may be appropriately adjusted within a range that can be easily changed by those skilled in the art.
In detail, the first portion 21000 can include an aerosol generating substance. Here, examples of aerosol-generating substances may include, but are not limited to, glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.
The second portion 22000 can include a tobacco material. For example, in the case of a general combustion type cigarette or a heating type cigarette, tobacco shreds may be used as the tobacco material. However, in the present disclosure, second portion 22000 may comprise a tobacco sheet that extends continuously in length. Details of the second portion 22000 will be described below with reference to fig. 5 and 6.
The third portion 23000 can cool the airflow that has passed through the first portion 21000 and the second portion 22000. The third portion 23000 can be made of a polymeric material or a biodegradable polymeric material, and can have a cooling function. For example, the third portion 23000 can be made of polylactic acid (PLA) fibers, but is not limited thereto. Further, the third portion 23000 can be made of a cellulose acetate filter having a plurality of holes. However, the third portion 23000 is not limited to the above example, and a material for cooling the aerosol may correspond thereto without limitation. For example, the third portion 23000 can be a tube filter or a paper tube including a hollow portion.
The fourth portion 24000 may include filter material. For example, the fourth portion 24000 may be a cellulose acetate filter. However, there is no limitation on the shape of the fourth portion 24000. For example, the fourth portion 24000 may be a cylindrical-shaped bar or a tubular-shaped bar including a hollow interior. Further, the fourth portion 24000 may be a recessed bar. If the fourth portion 24000 includes a plurality of segments, at least one of the plurality of segments may be manufactured in a different shape.
The fourth portion 24000 may be manufactured to produce scents. By way of example, the scented liquid may be sprayed on the fourth portion 24000, or individual fibers coated with the scented liquid may be inserted into the fourth portion 24000.
The aerosol-generating article 20000 may comprise a package 25000 surrounding at least a portion of the first portion 21000 to the fourth portion 24000. Additionally, the aerosol-generating article 20000 may comprise a package 25000 surrounding all of the first portion 21000 to the fourth portion 24000. The package 25000 may be located at the outermost portion of the aerosol-generating article 20000, and at least one aperture may be formed in the package 25000 through which external air may be introduced or internal gases may be expelled. Package 25000 can be a single package or a combination of multiple packages.
As an example, the first portion 21000 of the aerosol-generating article 20000 may comprise a crimped sheet containing an aerosol-generating substance, the second portion 22000 may comprise a tobacco sheet containing tobacco material and extending continuously in length, the third portion 23000 may comprise a cooling unit, and the fourth portion 24000 may comprise a filter material. However, the embodiment is not limited thereto.
The first portion 21000 and the second portion 22000 of the aerosol-generating article 20000 may be inserted into the interior of the aerosol-generating device 10000 and the third portion 23000 and the fourth portion 24000 of the aerosol-generating article 20000 may be exposed to the exterior of the aerosol-generating device 10000. Additionally, a portion of the second portion 22000 and the first portion 21000 may be inserted into the interior of the aerosol-generating device 10000. The user can inhale the aerosol when positioned in the fourth portion 24000 into the mouth. In this case, aerosol may be generated when external air passes through the first and second portions, and the generated aerosol may be delivered to the mouth of the user through the third and fourth portions.
In the following, the second portion 22000 of the aerosol-generating article 20000 will be described in detail with reference to fig. 5 and 6.
Figure 5 is a view illustrating the configuration of a first portion 21000 and a second portion 22000 of an aerosol-generating article 20000 according to an embodiment. The first portion 21000 can include an aerosol generating substance.
Referring to fig. 5, the second portion 22000 can include a tobacco sheet. The tobacco sheet may have a rectangular shape in the fully expanded state. For example, the tobacco sheet may have a rectangular shape or a square shape. However, the present invention is not necessarily limited thereto, and the shape of the tobacco sheet may be changed as needed.
In embodiments, the ratio of the vertical length to the horizontal length of the tobacco sheet may be from about 10:1 to about 30: 1. For example, the ratio of the vertical length to the horizontal length of the tobacco sheet may be about 18:1, about 19:1, about 20:1, about 21:1, about 22:1, about 23:1, or about 24: 1. As such, the inhalation resistance of the aerosol-generating article 20000 according to embodiments may be relatively low and the thermal conductivity of the aerosol-generating article 20000 may be improved. Thus, in the case of the aerosol-generating article 20000, the user may feel an excellent smoking experience.
In embodiments, the tobacco sheet may have a length of about 180mm or more in one direction. For example, the tobacco sheet may have a length in one direction of about 190mm to about 240 mm. Here, the length of the tobacco sheet in one direction may be a horizontal length, a vertical length, or a diagonal length. Preferably, the length of the tobacco sheet in one direction may be the horizontal length of the tobacco sheet. For example, the tobacco sheet may be 230mm by 12mm in size. As another example, the tobacco sheet may be 190mm x 8mm in size, but embodiments are not limited thereto. In case the length of the tobacco sheet in one direction is about 180mm or more, the thermal conductivity of the aerosol-generating article 20000 may be increased. Thus, in the case of the aerosol-generating article 20000, the user may feel an excellent smoking experience.
In embodiments, the second portion 22000 can comprise one or two tobacco sheets. For example, the second portion 22000 may comprise one tobacco sheet having dimensions of 230mm x12mm or 190mm x 8 mm. As another example, the second portion 22000 may comprise two tobacco sheets produced by cutting a tobacco sheet having dimensions of 230mm x12mm or 190mm x 8mm once. In an embodiment, when the second portion 22000 comprises one tobacco sheet having a size of 230mm x12mm or 190mm x 8mm, the inhalation resistance of the aerosol-generating article 20000 may be relatively reduced and the thermal conductivity of the aerosol-generating article 20000 may be improved compared to the case of comprising cut tobacco. As a result, the user may feel an excellent smoking experience in respect of the aerosol-generating article 20000.
In an embodiment, the tobacco sheet may include 75 to 85 parts by weight tobacco leaf, 5 to 20 parts by weight humectant, 3 to 10 parts by weight pulp, and 3 to 10 parts by weight viscosity agent (viscocity agent), based on 100 parts by weight total. In detail, the tobacco sheet may be reconstituted tobacco comprising the components in the above weight ratios.
In embodiments, the tobacco sheet may have a corrugated form or may be folded one or more times. Referring to fig. 5, it can be seen that second portion 22000 comprises a tobacco sheet in the form of a pleat or fold one or more times. Since the length of the tobacco sheet in one direction is about 180mm or more, the tobacco sheet may be difficult to accommodate in the second portion 22000 in a fully expanded form. Accordingly, the tobacco sheet may be included in the second portion 22000 in a corrugated form or a folded form having one or more folds (folds). In the following, the tobacco sheet 22000 will be described in more detail with reference to fig. 6.
Figure 6 is a view showing a cross-section of a second portion 22000 of an aerosol-generating article 20000 according to an exemplary embodiment.
The outermost portion of second portion 22000 may be package 25000. Inside the package 25000, the tobacco sheet 100 described above can be included in a corrugated form or a folded form. Referring to fig. 6, the tobacco sheet 100 may be included in a folded form having 8 or more folds. However, the embodiment is not limited thereto. When the tobacco sheet 100 is placed in the second portion 22000 in this manner, the air flow may pass through the second portion 22000 with relatively low resistance. Accordingly, the aerosol-generating article 20000 may have a relatively low inhalation resistance.
In an embodiment, a cross-section taken perpendicular to the length direction of the second portion 22000 can have at least one closed curve formed by the tobacco sheet. Although not shown in figure 6, when the tobacco sheet 100 has a corrugated form or is folded one or more times, at least one closed curve may be formed by two portions in contact with each other. A continuous air flow may be formed in the closed curve formed by tobacco sheet 100, and thus, the air flow may pass through second portion 22000 with relatively low resistance. Accordingly, the aerosol-generating article 20000 may have a relatively low inhalation resistance.
In an embodiment, the aerosol-generating article 20000 may have a mmH of about 20mmH2O to about 60mmH2Suction resistance of O. About 20mmH2O to about 60mmH2The inhalation resistance of O is considered in the art to be a relatively low value, which allows the user to smoothly inhale the aerosol. As a result, the user may feel an excellent smoking experience in respect of the aerosol-generating article 20000.
Figure 7A is a diagram illustrating how heat is transferred in cut tobacco according to an embodiment.
Figure 7B is a diagram illustrating how heat is transferred in a continuous tobacco sheet according to an embodiment.
Referring to figure 7A, when the aerosol-generating article comprises tobacco material in the form of cut tobacco, it can be seen that heat transferred from the package is transferred discontinuously between the tobacco material. In contrast, referring to figure 7B, when the second portion 22000 of the aerosol-generating article comprises tobacco material in the form of a tobacco sheet, it can be seen that heat transferred from the package 25000 is continuously transferred within the tobacco sheet 200. As a result, the tobacco sheet 200 can be heated efficiently and the user can feel an excellent smoking experience in the case of the aerosol-generating article 20000.
Figure 8A is a diagram illustrating airflow in cut tobacco.
Figure 8B is a diagram showing air flow in one continuous tobacco sheet.
Referring to figure 8A, when the aerosol-generating article comprises tobacco material in the form of cut tobacco sheets, it can be seen that a congested airflow is formed between the cut tobacco sheets by heating the generated aerosol.
In contrast, referring to fig. 8B, the second portion 22000 of the aerosol-generating article according to embodiments comprises one tobacco sheet 300 and the aerosol forms a vertical airflow in the vicinity of the tobacco sheet 300. Thus, as compared to fig. 8A, airflow may pass through the second portion 22000 with relatively low resistance. Thus, the aerosol-generating article 20000 may have a relatively low inhalation resistance and the user may feel an excellent smoking experience in terms of the aerosol-generating article 20000.
According to an embodiment, the aerosol-generating system may comprise the aerosol-generating article 20000 described above and an aerosol-generating device (not shown) that heats at least one of the first portion 21000 and the second portion 22000 of the aerosol-generating article 20000.
The features described above in relation to the generation article 20000 may be applied to an aerosol-generating article comprised in an aerosol-generating system.
In an embodiment, the second portion 22000 can comprise a tobacco sheet folded one or more times, and the aerosol-generating device can generate an aerosol by heating at least a portion of the first portion 21000 and at least a portion of the second portion 22000. .
