Therefore, the terms used in the present invention should be defined based on the meanings of the terms and the overall contents of the present invention, rather than simply the names of the terms.

When a part of the specification is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise specifically stated. In addition, terms such as "part", "module", etc., described in the specification mean a unit that processes at least one function or operation, which may be implemented by hardware or software, or a combination of hardware and software.

Below, with reference to the attached drawings, embodiments of the present invention are described in detail so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein.

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

Figures 1 to 3 are drawings illustrating examples of cigarettes inserted into an aerosol generating device.

Referring to Fig. 1, the aerosol generating device (1) includes a battery (11), a control unit (12), and a heater (13). Referring to Figs. 2 and 3, the aerosol generating device (1) further includes a vaporizer (14). In addition, a cigarette (2) can be inserted into the internal space of the aerosol generating device (1).

The aerosol generating device (1) illustrated in FIGS. 1 to 3 illustrates components related to the present embodiment. Accordingly, a person having ordinary skill in the art related to the present embodiment will understand that, in addition to the components illustrated in FIGS. 1 to 3, other general-purpose components may be further included in the aerosol generating device (1).

In addition, although FIGS. 2 and 3 illustrate that the aerosol generating device (1) includes a heater (13), the heater (13) may be omitted if necessary.

In Fig. 1, a battery (11), a control unit (12), and a heater (13) are illustrated as being arranged in a row. In addition, in Fig. 2, a battery (11), a control unit (12), a vaporizer (14), and a heater (13) are illustrated as being arranged in a row. In addition, in Fig. 3, a vaporizer (14) and a heater (13) are illustrated as being arranged in parallel. However, the internal structure of the aerosol generating device (1) is not limited to that illustrated in Figs. 1 to 3. In other words, depending on the design of the aerosol generating device (1), the arrangement of the battery (11), the control unit (12), the heater (13), and the vaporizer (14) may be changed.

When a cigarette (2) is inserted into an aerosol generating device (1), the aerosol generating device (1) can generate an aerosol by operating a heater (13) and/or a vaporizer (14). The aerosol generated by the heater (13) and/or the vaporizer (14) passes through the cigarette (2) and is delivered to the user.

If necessary, the aerosol generating device (1) can heat the heater (13) even when the cigarette (2) is not inserted into the aerosol generating device (1).

The battery (11) supplies power used to operate the aerosol generating device (1). For example, the battery (11) can supply power so that the heater (13) or the vaporizer (14) can be heated, and can supply power required for the control unit (12) to operate. In addition, the battery (11) can supply power required for the display, sensor, motor, etc. installed in the aerosol generating device (1) to operate.

The control unit (12) controls the overall operation of the aerosol generating device (1). Specifically, the control unit (12) controls the operation of the battery (11), the heater (13), and the vaporizer (14) as well as other components included in the aerosol generating device (1). In addition, the control unit (12) can check the status of each component of the aerosol generating device (1) to determine whether the aerosol generating device (1) is in an operable state.

The control unit (12) includes 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 that can be executed by the microprocessor. In addition, it will be understood by those skilled in the art to which the present embodiment belongs that the processor may be implemented as other types of hardware.

The heater (13) can be heated by power supplied from the battery (11). For example, when a cigarette is inserted into the aerosol generating device (1), the heater (13) can be located outside the cigarette. Accordingly, the heated heater (13) can increase the temperature of the aerosol generating material inside the cigarette.

The heater (13) may be an electrical resistance heater. For example, the heater (13) may include an electrically conductive track, and the heater (13) may be heated as current flows through the electrically conductive track. However, the heater (13) is not limited to the above-described example, and may be applied without limitation as long as it can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating device (1), or may be set to a desired temperature by the user.

Meanwhile, as another example, the heater (13) may be an induction heating heater. Specifically, the heater (13) may include an electrically conductive coil for heating the cigarette in an induction heating manner, and the cigarette may include a susceptor that can be heated by the induction heating heater.

For example, the heater (13) may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the inside or the outside of the cigarette (2) depending on the shape of the heating element.

In addition, a plurality of heaters (13) may be arranged in the aerosol generating device (1). At this time, the plurality of heaters (13) may be arranged to be inserted into the inside of the cigarette (2) or may be arranged on the outside of the cigarette (2). In addition, some of the plurality of heaters (13) may be arranged to be inserted into the inside of the cigarette (2), and the rest may be arranged on the outside of the cigarette (2). In addition, the shape of the heater (13) is not limited to the shape illustrated in FIGS. 1 to 3, and may be manufactured in various shapes.

The vaporizer (14) can heat the liquid composition to generate an aerosol, and the generated aerosol can be delivered to the user through the cigarette (2). In other words, the aerosol generated by the vaporizer (14) can travel along the airflow passage of the aerosol generating device (1), and the airflow passage can be configured so that the aerosol generated by the vaporizer (14) can pass through the cigarette and be delivered to the user.

For example, the vaporizer (14) may include, but is not limited to, a liquid reservoir, a liquid delivery means, and a heating element. For example, the liquid reservoir, the liquid delivery means, and the heating element may be included in the aerosol generating device (1) as independent modules.

The liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing a tobacco-containing material including a volatile tobacco flavoring component, or can be a liquid containing a non-tobacco material. The liquid reservoir can be constructed to be detachable from/attachable to the vaporizer (14), or can be constructed integrally with the vaporizer (14).

For example, the liquid composition may include water, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin mixture. The flavoring agent may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit-flavored ingredients, and the like. The flavoring agent may include ingredients that can provide a variety of flavors or tastes to the user. The vitamin mixture may include, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. In addition, the liquid composition may include an aerosol forming agent, such as glycerin and propylene glycol.

The liquid transfer means can transfer the liquid composition from the liquid storage to the heating element. For example, the liquid transfer means can be a wick such as, but not limited to, cotton fibers, ceramic fibers, glass fibers, or porous ceramics.

The heating element is an element for heating a liquid composition delivered by a liquid delivery means. For example, the heating element may be, but is not limited to, a metal heating wire, a metal heating plate, a ceramic heater, etc. In addition, the heating element may be composed of a conductive filament such as a nichrome wire, and may be arranged in a structure that is wound around the liquid delivery means. The heating element may be heated by supplying 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 may be generated.

For example, the vaporizer (14) may be referred to as a cartomizer or an atomizer, but is not limited thereto.

Meanwhile, the aerosol generating device (1) may further include general-purpose components in addition to the battery (11), the control unit (12), the heater (13), and the vaporizer (14). For example, the aerosol generating device (1) may include a display capable of outputting visual information and/or a motor for outputting tactile information. In addition, the aerosol generating device (1) may include at least one sensor (a puff detection sensor, a temperature detection sensor, a cigarette insertion detection sensor, etc.). In addition, the aerosol generating device (1) may be manufactured with a structure in which external air may be introduced or internal gas may be discharged even when the cigarette (2) is inserted.

Although not shown in FIGS. 1 to 3, the aerosol generating device (1) may also be configured as a system with a separate cradle. For example, the cradle may be used to charge the battery (11) of the aerosol generating device (1). Alternatively, the heater (13) may be heated while the cradle and the aerosol generating device (1) are combined.

The cigarette (2) may be similar to a typical combustible cigarette. For example, the cigarette (2) may be divided into a first part containing an aerosol generating substance and a second part containing a filter or the like. Alternatively, the second part of the cigarette (2) may also contain an aerosol generating substance. For example, an aerosol generating substance in the form of granules or capsules may be inserted into the second part.

The entire first part may be inserted into the interior of the aerosol generating device (1), and the second part may be exposed to the outside. Alternatively, only a part of the first part may be inserted into the interior of the aerosol generating device (1), or the entire first part and a part of the second part may be inserted. The user may inhale the aerosol while holding the second part in his mouth. At this time, the aerosol is generated by the outside air passing through the first part, and the generated aerosol is delivered to the user's mouth through the second part.

As an example, outside air may be introduced through at least one air passage formed in the aerosol generating device (1). For example, the opening and closing of the air passage formed in the aerosol generating device (1) and/or the size of the air passage may be controlled by the user. Accordingly, the amount of vapor, the smoking sensation, etc. may be controlled by the user. As another example, outside air may be introduced into the interior of the cigarette (2) through at least one hole formed on the surface of the cigarette (2).

Below, examples of cigarettes (2) are described with reference to FIGS. 4 and 5.

Figures 4 and 5 are drawings illustrating examples of cigarettes.

Referring to FIG. 4, the cigarette (2) includes a tobacco rod (21) and a filter rod (22). The first part (21) described above with reference to FIGS. 1 to 3 includes the tobacco rod (21), and the second part (22) includes the filter rod (22).

In Fig. 4, the filter load (22) is illustrated as a single segment, but is not limited thereto. In other words, the filter load (22) may be composed of a plurality of segments. For example, the filter load (22) may include a segment for cooling the aerosol and a segment for filtering a predetermined component contained in the aerosol. In addition, if necessary, the filter load (22) may further include at least one segment for performing another function.

The diameter of the cigarette (2) is within a range of 5 mm to 9 mm, and the length may be about 48 mm, but is not limited thereto. For example, the length of the tobacco rod (21) may be about 12 mm, the length of the first segment of the filter rod (22) may be about 10 mm, the length of the second segment of the filter rod (22) may be about 14 mm, and the length of the third segment of the filter rod (22) may be about 12 mm, but is not limited thereto.

The cigarette (2) may be wrapped by at least one wrapper (24). The wrapper (24) may have at least one hole formed therein through which outside air is introduced or internal gas is discharged. As an example, the cigarette (2) may be wrapped by one wrapper (24). As another example, the cigarette (2) may be wrapped by two or more wrappers (24) in an overlapping manner. For example, the tobacco rod (21) may be wrapped by a first wrapper (241), and the filter rod (22) may be wrapped by wrappers (242, 243, 244). Then, the entire cigarette (2) may be repackaged by a single wrapper (245). If the filter rod (22) is composed of a plurality of segments, each segment may be wrapped by wrappers (242, 243, 244).

The first wrapper (241) and the second wrapper (242) can be made of general filter paper. For example, the first wrapper (241) and the second wrapper (242) can be porous paper or non-porous paper. In addition, the first wrapper (241) and the second wrapper (242) can be made of oil-resistant paper and/or aluminum composite packaging material.

The third wrapper (243) can be made of hard paper. For example, the basis weight of the third wrapper (243) can be included in the range of 88 g/m ² to 96 g/m ² , and preferably can be included in the range of 90 g/m ² to 94 g/m ² . In addition, the thickness of the third wrapper (243) can be included in the range of 120 ㎛ to 130 ㎛, and preferably can be 125 ㎛.

The fourth wrapper (244) can be made of a hard paper having a high oil resistance. For example, the weight of the fourth wrapper (244) can be included in a range of 88 g/m ² to 96 g/m ² , and preferably can be included in a range of 90 g/m ² to 94 g/m ² . In addition, the thickness of the fourth wrapper (244) can be included in a range of 120 μm to 130 μm, and preferably can be 125 μm.

The fifth wrapper (245) can be made of sterilized paper (MFW). Here, the sterilized paper (MFW) means paper specially manufactured to have improved tensile strength, water resistance, smoothness, etc. compared to general paper. For example, the basis weight of the fifth wrapper (245) can be within a range of 57 g/m ² to 63 g/m ² , and preferably 60 g/m ² . In addition, the thickness of the fifth wrapper (245) can be within a range of 64 ㎛ to 70 ㎛, and preferably 67 ㎛.

The fifth wrapper (245) may have a predetermined material added thereto. Here, an example of the predetermined material may be silicon, but is not limited thereto. For example, silicon has properties such as heat resistance that is less affected by temperature, oxidation resistance that does not oxidize, resistance to various chemicals, water repellency, or electrical insulation. However, even if it is not silicon, any material having the above-described properties may be applied (or coated) to the fifth wrapper (245) without limitation.

The fifth wrapper (245) can prevent the cigarette (2) from burning. For example, if the tobacco rod (210) is heated by the heater (13), there is a possibility that the cigarette (2) will burn. Specifically, if the temperature rises above the ignition point of any one of the materials included in the tobacco rod (310), the cigarette (2) may burn. Even in this case, since the fifth wrapper (245) includes a non-combustible material, the cigarette (2) can be prevented from burning.

In addition, the fifth wrapper (245) can prevent the holder (1) from being contaminated by substances generated from the cigarette (2). Liquid substances may be generated inside the cigarette (2) by the user's puff. For example, liquid substances (e.g., moisture, etc.) may be generated when the aerosol generated inside the cigarette (2) is cooled by the outside air. As the fifth wrapper (245) wraps the cigarette (2), liquid substances generated inside the cigarette (2) can be prevented from leaking out of the cigarette (2).

The tobacco rod (21) contains an aerosol generating substance. For example, the aerosol generating substance may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. In addition, the tobacco rod (21) may contain other additives such as a flavoring agent, a humectant, and/or an organic acid. In addition, a flavoring liquid such as menthol or a humectant may be added to the tobacco rod (21) by spraying it onto the tobacco rod (21).

The tobacco rod (21) can be manufactured in various ways. For example, the tobacco rod (21) can be manufactured as a sheet or as a strand. In addition, the tobacco rod (21) can be manufactured as a cut tobacco sheet. In addition, the tobacco rod (21) can be surrounded by a heat-conducting material. For example, the heat-conducting material can be a metal foil such as aluminum foil, but is not limited thereto. For example, the heat-conducting material surrounding the tobacco rod (21) can evenly distribute the heat transferred to the tobacco rod (21) to improve the heat conductivity applied to the tobacco rod, thereby improving the taste of the tobacco. In addition, the heat-conducting material surrounding the tobacco rod (21) can function as a susceptor heated by an induction heater. At this time, although not shown in the drawing, the tobacco rod (21) can further include an additional susceptor in addition to the heat-conducting material surrounding the outside.

The filter rod (22) may be a cellulose acetate filter. Meanwhile, there is no limitation on the shape of the filter rod (22). For example, the filter rod (22) may be a cylindrical rod or a tube-shaped rod having a hollow portion therein. In addition, the filter rod (22) may be a recessed rod. If the filter rod (22) is composed of a plurality of segments, at least one of the plurality of segments may be manufactured in a different shape.

The first segment of the filter rod (22) may be a cellulose acetate filter. For example, the first segment may be a tube-shaped structure including a hollow space therein. When the heater (13) is inserted by the first segment, the phenomenon of the internal material of the tobacco rod (210) being pushed back may be prevented, and a cooling effect of the aerosol may also be generated. The diameter of the hollow space included in the first segment may be adopted as an appropriate diameter within a range of 2 mm to 4.5 mm, but is not limited thereto.

The length of the first segment may be adopted as an appropriate length within the range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first segment may be 10 mm, but is not limited thereto.

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

The second segment of the filter rod (22) cools the aerosol generated by the heater (13) heating the tobacco rod (21). Accordingly, the user can inhale the aerosol cooled to an appropriate temperature.

The length or diameter of the second segment can be determined variously depending on the shape of the cigarette (2). For example, the length of the second segment can be appropriately adopted within a range of 7 mm to 20 mm. Preferably, the length of the second segment can be about 14 mm, but is not limited thereto.

The second segment can be manufactured by weaving polymer fibers. In this case, a flavoring agent can be applied to the fibers manufactured from the polymer. Alternatively, a separate fiber to which a flavoring agent has been applied and a fiber manufactured from the polymer can be woven together to manufacture the second segment. Alternatively, the second segment can be formed by a crimped polymer sheet.

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

As the second segment is formed by a woven polymer fiber or a crimped polymer sheet, the second segment may include a single or multiple longitudinally extending channels. Here, a channel means a passage through which a gas (e.g., air or an aerosol) passes.

For example, the second segment comprised of the compressed polymer sheet can be formed from a material having a thickness of between about 5 μm and about 300 μm, for example between about 10 μm and about 250 μm. Furthermore, the total surface area of the second segment can be between about 300 mm ² /mm and about 1000 mm ² /mm. Furthermore, the aerosol-cooling element can be formed from a material having a specific surface area of between about 10 mm ² /mg and about 100 mm ² /mg.

Meanwhile, the second segment may include a thread containing a volatile flavor component. Here, the volatile flavor component may be, but is not limited to, menthol. For example, the thread may be filled with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

The third segment of the filter load (22) may be a cellulose acetate filter. The length of the third segment may be suitably adopted within a range of 4 mm to 20 mm. For example, the length of the third segment may be about 12 mm, but is not limited thereto.

In the process of manufacturing the third segment, it may be manufactured so that flavor is generated by spraying a flavoring agent into the third segment. Alternatively, a separate fiber coated with a flavoring agent may be inserted into the interior of the third segment. The aerosol generated from the tobacco rod (21) is cooled as it passes through the second segment of the filter rod (22), and the cooled aerosol is delivered to the user through the third segment. Therefore, when a flavoring element is added to the third segment, the effect of increasing the persistence of flavor delivered to the user can be generated.

In addition, the filter rod (22) may include at least one capsule (23). Here, the capsule (23) may perform a function of generating a flavor or a function of generating an aerosol. For example, the capsule (23) may be a structure in which a liquid containing a flavor is wrapped with a film. The capsule (23) may have a spherical or cylindrical shape, but is not limited thereto.

Referring to FIG. 5, the cigarette (3) may further include a shear plug (33). The shear plug (33) may be located on one side of the tobacco rod (31) facing the filter rod (32). The shear plug (33) may prevent the tobacco rod (31) from escaping to the outside, and may prevent liquefied aerosol from the tobacco rod (31) from flowing into the aerosol generating device (FIGS. 1 to 3) during smoking.

The filter load (32) may include a first segment (321) and a second segment (322). Here, the first segment (321) may correspond to the first segment of the filter load (22) of FIG. 4, and the second segment (322) may correspond to the third segment of the filter load (22) of FIG. 4.

The diameter and overall length of the cigarette (3) may correspond to the diameter and overall length of the cigarette (2) of Fig. 4. For example, the length of the shear plug (33) may be about 7 mm, the length of the tobacco rod (31) may be about 15 mm, the length of the first segment (321) may be about 12 mm, and the length of the second segment (322) may be about 14 mm, but is not limited thereto.

The cigarette (3) may be wrapped by at least one wrapper (35). The wrapper (35) may have at least one hole formed through which outside air is introduced or internal gas is discharged. For example, the shear plug (33) may be wrapped by the first wrapper (351), the tobacco rod (31) may be wrapped by the second wrapper (352), the first segment (321) may be wrapped by the third wrapper (353), and the second segment (322) may be wrapped by the fourth wrapper (354). Then, the entire cigarette (3) may be repackaged by the fifth wrapper (355).

In addition, at least one perforation (36) may be formed in the fifth wrapper (355). For example, the perforation (36) may be formed in an area surrounding the tobacco rod (31), but is not limited thereto. The perforation (36) may serve to transfer heat formed by the heater (13) illustrated in FIGS. 2 and 3 to the interior of the tobacco rod (31).

In addition, the second segment (322) may include at least one capsule (34). Here, the capsule (34) may perform a function of generating a flavor or a function of generating an aerosol. For example, the capsule (34) may be a structure in which a liquid including a flavor is wrapped with a film. The capsule (34) may have a spherical or cylindrical shape, but is not limited thereto.

The first wrapper (351) may be a general filter paper combined with a metal foil such as aluminum foil. For example, the overall thickness of the first wrapper (351) may be included in a range of 45 ㎛ to 55 ㎛, preferably 50.3 ㎛. In addition, the thickness of the metal foil of the first wrapper (351) may be included in a range of 6 ㎛ to 7 ㎛, preferably 6.3 ㎛. In addition, the basis weight of the first wrapper (351) may be included in a range of 50 g/m ² to 55 g/m ² , preferably 53 g/m ² .

The second wrapper (352) and the third wrapper (353) can be made of general filter paper. For example, the second wrapper (352) and the third wrapper (353) can be porous paper or non-porous paper.

For example, the porosity of the second wrapper (352) may be, but is not limited to, 35000 CU. In addition, the thickness of the second wrapper (352) may be included in a range of 70 ㎛ to 80 ㎛, and preferably may be 78 ㎛.
