When a hub device such as an access point (AP) is present around theelectronic device 100, thecontroller 210 may use the hub device to communicate with the server. - For example, a heating profile of a cigarette may be stored in an external server, and a heating profile for each cigarette type may be transmitted from the external server to the
electronic device 100 at the request of theelectronic device 100. -
FIG. 3 is a diagram illustrating a configuration of a controller according to an example embodiment. - According to an example embodiment, the
controller 210 may include acommunication unit 310, aprocessor 320, and amemory 330. - The
communication unit 310 may be connected to theprocessor 320 and thememory 330 to transmit and receive data thereto and therefrom. Thecommunication unit 310 may be connected to another external device to transmit and receive data thereto and therefrom. Hereinafter, transmitting and receiving “A” may refer to transmitting and receiving “information or data indicating A.” - The
communication unit 310 may be implemented as a circuitry in thecontroller 210. For example, thecommunication unit 310 may include an internal bus and an external bus. For another example, thecommunication unit 310 may be an element that connects thecontroller 210 and an external device. Thecommunication unit 310 may be an interface.

processor 320 may process the data received by thecommunication unit 310 and data stored in thememory 330. A processor described herein may be a hardware-implemented processing device having a physically structured circuit to execute operations. The operations may include, for example, code or instructions included in a program. The hardware-implemented data processing device may include, for example, a microprocessor, a central processing unit (CPU), a processor core, a multi-core processor, a multiprocessor, an application-specific integrated circuit (ASIC), and a field-programmable gate array (FPGA). - The
processor 320 may execute computer-readable code (e.g., software) stored in a memory (e.g., the memory 330) and instructions triggered by theprocessor 320. - The
memory 330 may store therein the data received by thecommunication unit 310 and the data processed by theprocessor 320. For example, thememory 330 may store therein the program (or an application, or software). The program to be stored may be a set of syntaxes that are coded and executable by theprocessor 320 to control theelectronic device 100. - The
memory 330 may include, for example, at least one volatile memory, non-volatile memory, random-access memory (RAM), flash memory, hard disk drive, and optical disc drive. - The
memory 330 may store an instruction set (e.g., software) for operating thecontroller 210. The instruction set for operating thecontroller 210 may be executed by theprocessor 320. - The
communication unit 310, theprocessor 320, and thememory 330 will be described in detail below with reference toFIGS. 4 a, 4 b , and 5. -
FIGS. 4 a and 4 b are diagrams illustrating examples of a screen displayed on an electronic device according to an example embodiment. - According to an example embodiment, the
processor 320 described above with reference toFIG. 3 may detect whether thecigarette 2 is inserted in theinserter 250. According to another example embodiment, a sensor for detecting a type of thecigarette 2 may be further included in the inserter 250 (or in a portion adjacent to the inserter 250), and theprocessor 320 may detect the type of thecigarette 2, in addition to the insertion of thecigarette 2, using the sensor. - The
processor 320 may display, through thedisplay unit 220, an icon for a cigarette type theelectronic device 100 supports. According to an example embodiment, the supported cigarette type may include, as non-limiting examples, a cut tobacco type, a granular type, and a liquid type, and may be implemented in various ways. For example, theprocessor 320 may display different icons for different cigarette types having different heating profiles including information on an appropriate heating temperature and an appropriate heating time. -
FIG. 4 a illustrates a main screen displayed through thedisplay 120 of theelectronic device 100. On the main screen, anicon 410 for setting the use of theelectronic device 100, anicon 420 for setting a communication state (e.g., bluetooth status), and anicon 430 for checking battery information may be displayed. On the main screen,time information 440 andweather information 450 may also be displayed. When a user taps (or touches) theicon 410 for setting the use, settings for heating theheater 240 may be displayed as shown inFIG. 4 b. -
FIG. 4 b illustrates a screen for setting theheater 240 displayed on thedisplay 120 of theelectronic device 100. According to an example embodiment, the screen ofFIG. 4 b may be displayed when thecigarette 2 is detected as inserted. According to another example embodiment, the screen ofFIG. 4 b may be displayed by auser input 415 to theicon 410 for setting the use on the main screen ofFIG. 4 a , after the user inserts thecigarette 2 to heat the aerosol-generating substrate. - Referring to
FIG. 4 b ,icons electronic device 100 may be displayed. Although theicon 471 for a cut tobacco type, theicon 474 for a granular type, and theicon 477 for a liquid type are displayed on the screen inFIG. 4 b , examples of icons are not illustrated thereto, and various icons may be displayed for cigarettes having different heating profiles. In addition to such icons for supported cigarette types,time information 460 and the like may be displayed on the screen. - According to an example embodiment, when the
processor 320 detects the type of thecigarette 2 through the sensor for detecting a type of a cigarette included in theinserter 250, a different visual effect may be applied to an icon corresponding to the detected type of thecigarette 2. For example, when theprocessor 320 detects a type of an inserted cigarette as a cut tobacco type, theprocessor 320 may display the background color of theicon 471 for the cut tobacco type to be different from those of other icons (e.g., theicons 474 and 477), or may display a message, for example, “Currently, a cigarette of the cut tobacco type is inserted.” - According to an example embodiment, in addition to the basic settings for the cut tobacco type, granular type, and liquid type shown in
FIG. 4 b , the user may set an appropriate heating temperature and appropriate heating time to generate a new heating profile, and an icon corresponding to the newly generated heating profile may be further displayed. The user may then set a name for the newly created heating profile. - According to an example embodiment, the user may check a cigarette type (or heating profile) by swiping up and down the list of heating profiles, and may bookmark a frequently used type or delete an unused type.
- When the user selects a cigarette type, the
processor 320 may determine a corresponding heating profile and heat an aerosol-generating substrate of an inserted cigarette based on the determined heating profile. For example, when the user taps theicon 471 for the cut tobacco type among the icons displayed on thedisplay 120 as shown byreference numeral 480, theprocessor 320 may determine a heating profile corresponding to the cut tobacco type, and heat an aerosol-generating substrate of a cigarette in theinserter 250 through theheater 240 based on the determined heating profile. - A heating profile may include at least one of an appropriate heating time or an appropriate heating temperature that is preset according to a cigarette type, and the
processor 320 may determine a heating profile corresponding to a cigarette type for which a user input is received by referring to heating profile information stored in thememory 330. According to another example embodiment, the heating profile information may be stored in an external server, and theprocessor 320 may obtain the heating profile information by requesting, from the external server through thecommunication unit 310, a heating profile corresponding to a cigarette type for which a user input is received. - The
processor 320 may heat the aerosol-generating substrate of thecigarette 2 in theinserter 250 through theheater 240 according to the appropriate heating temperature and the appropriate heating time based on the heating profile. -
FIG. 5 is a flowchart illustrating a method of heating an aerosol-generating substrate according to an example embodiment. -
Operations 510 to 540 described hereinafter may be performed by theprocessor 320 of theelectronic device 100 described above with reference toFIGS. 1 a through 4 b , and the description provided above will not be repeated for conciseness. - In
operation 510, theprocessor 320 may detect insertion of thecigarette 2. Theprocessor 320 may detect the insertion of thecigarette 2 through a sensor included in theinserter 250. According to an example embodiment, when a sensor for detecting a cigarette type is included in theinserter 250, theprocessor 320 may also simultaneously detect a type of a cigarette along with the insertion of the cigarette. - In
operation 520, theprocessor 320 may display an icon for a supported cigarette type. As described above with reference toFIG. 4 b , when theprocessor 320 detects the type of thecigarette 2 inoperation 510, a visual effect different from those for different icons may be applied to an icon corresponding to the detected type of thecigarette 2. - In
operation 530, theprocessor 320 may determine a corresponding heating profile based on a user input for the type of thecigarette 2. In this case, heating profile information may be stored in thememory 330, and may be obtained through a request to an external server through thecommunication unit 310. - In
operation 540, theprocessor 320 may heat an aerosol-generating substrate of thecigarette 2 based on the determined heating profile. For example, theprocessor 320 may heat the aerosol-generating substrate of thecigarette 2 in theinserter 250 through theheater 240 based on an appropriate heating temperature and an appropriate heating time of the heating profile. The user may then inhale, through thecigarette 2, an aerosol generated as the aerosol-generating substrate is heated. -
FIGS. 6 through 8 are diagrams illustrating examples of the insertion of a cigarette in an aerosol-generating device according to one or more example embodiments. - In the examples described hereinafter with reference to
FIGS. 6 through 8 , an aerosol-generatingdevice 1 may correspond to theelectronic device 100 described above with reference toFIGS. 1 a through 2. Abattery 11 may correspond to thebattery 230 described above with reference toFIG. 2 . Acontroller 12 may correspond to thecontroller 210 described above with reference toFIG. 2 . Avaporizer 14 or aheater 13 may correspond to theheater 240 described above with reference toFIG. 2 . - Referring to
FIG. 6 , the aerosol-generatingdevice 1 may include thebattery 11, thecontroller 12, and theheater 13. Referring toFIGS. 7 and 8 , the aerosol-generatingdevice 1 may further include thevaporizer 14. In addition, acigarette 2 may be inserted into an inner space of the aerosol-generatingdevice 1. - The aerosol-generating
device 1 shown inFIGS. 6 through 8 may include components related to the example embodiments described herein. Therefore, it is to be understood by those having ordinary skill in the art to which the present disclosure pertains that the aerosol-generatingdevice 1 may further include other generally used components in addition to the ones shown inFIGS. 6 through 8 . - In addition, although it is shown that the
heater 13 is included in the aerosol-generatingdevice 1 inFIGS. 7 and 8 , theheater 13 may be omitted as needed. -
FIG. 6 illustrates a linear alignment of thebattery 11, thecontroller 12, and theheater 13.FIG. 7 illustrates a linear alignment of thebattery 11, thecontroller 12, thevaporizer 14, and theheater 13.FIG. 8 illustrates a parallel alignment of thevaporizer 14 and theheater 13. However, the internal structure of the aerosol-generatingdevice 1 is not limited to what is shown inFIGS. 6 through 8 . That is, such alignments of thebattery 11, thecontroller 12, theheater 13, and thevaporizer 14 may be changed depending on the design of the aerosol-generatingdevice 1. - When the
cigarette 2 is inserted in the aerosol-generatingdevice 1, the aerosol-generatingdevice 1 may operate theheater 13 and/or thevaporizer 14 to generate an aerosol. The aerosol generated by theheater 13 and/or thevaporizer 14 may pass through thecigarette 2 into the user. - Even when the
cigarette 2 is not inserted in the aerosol-generatingdevice 1, the aerosol-generatingdevice 1 may heat theheater 13, as needed. - The
battery 11 may supply power to be used to operate the aerosol-generatingdevice 1. For example, thebattery 11 may supply power to heat theheater 13 or thevaporizer 14, and may supply power required for thecontroller 12 to operate. In addition, thebattery 11 may supply power required to operate a display, a sensor, a motor, or the like installed in the aerosol-generatingdevice 1. - The
controller 12 may control the overall operation of the aerosol-generatingdevice 1. For example, thecontroller 12 may control respective operations of other components included in the aerosol-generatingdevice 1, in addition to thebattery 11, theheater 13, and thevaporizer 14. In addition, thecontroller 12 may verify a state of each of the components of the aerosol-generatingdevice 1 to determine whether the aerosol-generatingdevice 1 is in an operable state. - The
controller 12 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 in which a program executable in the microprocessor is stored. In addition, it is to be understood by those having ordinary skill in the art to which the present disclosure pertains that the processor may be implemented in other types of hardware. - The
heater 13 may be heated by power supplied by thebattery 11. For example, when thecigarette 2 is inserted in the aerosol-generatingdevice 1, theheater 13 may be disposed outside thecigarette 2. Theheated heater 13 may thus raise the temperature of an aerosol-generating material in thecigarette 2. - For example, the
heater 13 may be an electrically resistive heater. In this example, theheater 13 may include an electrically conductive track, and theheater 13 may be heated as a current flows through the electrically conductive track. However, theheater 13 is not limited to the foregoing example, and any example of heating theheater 13 up to a desired temperature may be applicable without limitation. The desired temperature may be preset in the aerosol-generatingdevice 1 or may be set by the user. - For another example, the
heater 13 may be an inductive heating-type heater. In this example, theheater 13 may include an electrically conductive coil for heating thecigarette 2 in an inductive heating manner, and thecigarette 2 may include a susceptor to be heated by the inductive heating-type 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 outside of thecigarette 2 according to the shape of a heating element. - In addition, the
heater 13 may be provided as a plurality of heaters in the aerosol-generatingdevice 1. In this case, the heaters may be disposed to be inserted into thecigarette 2, or may be disposed outside thecigarette 2. In addition, some of the heaters may be disposed to be inserted into thecigarette 2, and the rest may be disposed outside thecigarette 2. However, the shape of theheater 13 is not limited to what is shown inFIGS. 6 through 8 but may be provided in various shapes. - The
vaporizer 14 may heat a liquid composition to generate an aerosol, and the generated aerosol may pass through thecigarette 2 into the user. That is, the aerosol generated by thevaporizer 14 may travel along an airflow path of the aerosol-generatingdevice 1, and the airflow path may be configured such that the aerosol generated by thevaporizer 14 passes through thecigarette 2 to be into the user. - For example, the
vaporizer 14 may include a liquid storage, a liquid transfer means, and a heating element, but is not limited thereto. For example, the liquid storage, the liquid transfer means, and the heating element may be included as independent modules in the aerosol-generatingdevice 1. - The liquid storage may store the liquid composition. The liquid composition may be, for example, a liquid including a tobacco-containing material that includes a volatile tobacco flavor component, or may be a liquid including a non-tobacco material. The liquid storage may be manufactured to be detachable and attachable from and to the
vaporizer 14, or may be manufactured in an integral form with thevaporizer 14. - The liquid composition may include, for example, water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. The fragrance may include, for example, menthol, peppermint, spearmint oil, various fruit flavors, and the like, but is not limited thereto. The flavoring agent may include ingredients that provide the user with a variety of flavors or scents. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C, or vitamin E, but is not limited thereto. The liquid composition may also include an aerosol former such as glycerin and propylene glycol.
- The liquid transfer means may transfer the liquid composition in the liquid storage to the heating element. The liquid transfer means may be, for example, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited thereto.
- The heating element may be an element for heating the liquid composition transferred by the liquid transfer means. The heating element may be, for example, a metal heating wire, a metal heating plate, a ceramic heater, or the like, but is not limited thereto. In addition, the heating element may include a conductive filament such as a nichrome wire, and may be arranged in a structure wound around the liquid transfer means. The heating element may be heated as a current is supplied and may transfer heat to the liquid composition in contact with the heating element, and may thereby heat the liquid composition. As a result, an aerosol may be generated.
- For example, the
vaporizer 14 may also be referred to as a cartomizer or an atomizer, but is not limited thereto. - The aerosol-generating
device 1 may further include general-purpose components in addition to thebattery 11, thecontroller 12, theheater 13, and thevaporizer 14. For example, the aerosol-generatingdevice 1 may include a display that outputs visual information and/or a motor that outputs tactile information. In addition, the aerosol-generatingdevice 1 may include at least one sensor (e.g., a puff sensor, a temperature sensor, a cigarette insertion detection sensor, etc.). In addition, the aerosol-generatingdevice 1 may be manufactured to have a structure allowing external air to be introduced or internal gas to flow out even while thecigarette 2 is inserted. - According to an embodiment, the aerosol-generating
device 1 may constitute a system along with a separate cradle. For example, the cradle may be used to charge thebattery 11 of the aerosol-generatingdevice 1. Alternatively, the cradle may be used to heat theheater 13, with the cradle and the aerosol-generatingdevice 1 coupled. - The
cigarette 2 may be of a similar type to a general burning type. For example, thecigarette 2 may be divided into a first portion including an aerosol-generating material and a second portion including a filter or the like. Alternatively, the second portion of thecigarette 2 may also include the aerosol-generating material. For example, the aerosol-generating material provided in the form of granules or capsules may be inserted into the second portion. - The first portion may be entirely inserted into the aerosol-generating
device 1, and the second portion may be exposed outside. Alternatively, the first portion may be partially inserted into the aerosol-generatingdevice 1, and the first portion may be entirely inserted and the second portion may be partially inserted into the aerosol-generatingdevice 1. The user may then inhale an aerosol with the second portion in their mouth. In this case, an aerosol may be generated as external air passes through the first portion, and the generated aerosol may pass through the second portion to be into the mouth of the user. - For example, the external air may be introduced through at least one air path formed in the aerosol-generating
device 1. In this example, the opening or closing and/or the size of the air path formed in the aerosol-generatingdevice 1 may be adjusted by the user. Accordingly, an amount of atomization, a sense of smoking, or the like may be adjusted by the user. For another example, the external air may be introduced into the inside of thecigarette 2 through at least one hole formed on a surface of thecigarette 2. - Hereinafter, examples of the
cigarette 2 will be described with reference toFIGS. 9 and 10 . -
FIGS. 9 and 10 are perspective views of examples of a cigarette according to an example embodiment. - A
cigarette 2 shown inFIGS. 9 and 10 may correspond to thecigarette 2 described above with reference toFIG. 1 c. - Referring to
FIG. 9 , thecigarette 2 may include atobacco rod 21 and afilter rod 22. The first portion and the second portion described above with reference toFIGS. 6 through 8 may include thetobacco rod 21 and thefilter rod 22, respectively. - Although the
filter rod 22 is illustrated as having a single segment inFIG. 9 , examples of which are not limited thereto. That is, thefilter rod 22 may include a plurality of segments. For example, thefilter rod 22 may include a segment that cools an aerosol and a segment that filters out certain components contained in an aerosol. In addition, thefilter rod 22 may further include at least one segment that performs another function, as needed. - A diameter of the
cigarette 2 may be in a range of 5 millimeters (mm) to 9 mm, and a length thereof may be approximately 48 mm. However, thecigarette 2 is not limited thereto. For example, a length of thetobacco rod 21 may be approximately 12 mm, a length of a first segment of thefilter rod 22 may be approximately 10 mm, a length of a second segment of thefilter rod 22 may be approximately 14 mm, and a length of a third segment of thefilter rod 22 may be approximately 12 mm. However, examples are not limited thereto. - The
cigarette 2 may be wrapped with at least onewrapper 24. Thewrapper 24 may have at least one hole through which external air is introduced or internal gas is discharged outside. For example, thecigarette 2 may be wrapped with onewrapper 24. For another example, thecigarette 2 may be wrapped with two ormore wrappers 24 in an overlapping manner. For example, thetobacco rod 21 may be wrapped with afirst wrapper 24 a, and thefilter rod 22 may be wrapped withwrappers cigarette 2 may be entirely wrapped again with asingle wrapper 24 e. For example, when thefilter rod 22 includes a plurality of segments, the segments may be wrapped with thewrappers - The
first wrapper 24 a and thesecond wrapper 24 b may be formed of general filter wrapping paper. For example, thefirst wrapper 24 a and thesecond wrapper 24 b may be porous wrapping paper or non-porous wrapping paper. In addition, thefirst wrapper 24 a and thesecond wrapper 24 b may be formed of oilproof paper and/or an aluminum laminated wrapping material. - The
third wrapper 24 c may be formed of hard wrapping paper. For example, a basis weight of thethird wrapper 24 c may be in a range of 88 grams per square meter (g/m2) to 96 g/m2, and may be in a range of 90 g/m2 to 94 g/m2. In addition, a thickness of thethird wrapper 24 c may be in a range of 120 micrometers (μm) to 130 μm, and may be 125 μm. - The
fourth wrapper 24 d may be formed of oilproof hard wrapping paper. For example, a basis weight of thefourth wrapper 24 d may be in a range of 88 g/m2 to 96 g/m2, and may be in a range of 90 g/m2 to 94 g/m2. In addition, a thickness of thefourth wrapper 24 d may be in a range of 120 μm to 130 μm, and may be 125 μm. - The
fifth wrapper 24 e may be formed of sterile paper (e.g., MFW). The sterilized paper (MFW) refers to paper specially prepared to enhance tensile strength, water resistance, smoothness, or the like, compared to general paper. For example, a basis weight of thefifth wrapper 24 e may be in a range of 57 g/m2 to 63 g/m2, and may be 60 g/m2. In addition, a thickness of thefifth wrapper 24 e may be in a range of 64 μm to 70 μm, and may be 67 μm. - The
fifth wrapper 24 e may have a predetermined material internally added thereto. The material may be, for example, silicon, but is not limited thereto. Silicon may have properties, such as, for example, heat resistance which is characterized by less change by temperature, oxidation resistance which refers to resistance to oxidation, resistance to various chemicals, water repellency against water, or electrical insulation. However, silicon may not be necessarily used, but any material having such properties described above may be applied (or coated) on thefifth wrapper 24 e without limitation. - The
fifth wrapper 24 e may prevent thecigarette 2 from burning. For example, there may be a probability that thecigarette 2 burns when thetobacco rod 21 is heated by theheater 13. For example, when the temperature rises above an ignition point of any one of materials included in thetobacco rod 21, thecigarette 2 may burn. Even in this case, it may still be possible to prevent thecigarette 2 from burning because thefifth wrapper 24 e includes a non-combustible material. - In addition, the
fifth wrapper 24 e may prevent aholder 1 from being contaminated by substances produced in thecigarette 2. For example, liquid substances may be produced in thecigarette 2 by puffs from the user. For example, as an aerosol generated in thecigarette 2 is cooled by external air, such liquid substances (e.g., water, etc.) may be produced. Thus, wrapping thecigarette 2 with thefifth wrapper 24 e may prevent the liquid substances produced in thecigarette 2 from leaking out of thecigarette 2. - The
tobacco rod 21 may include an aerosol-generating material. The aerosol-generating material may include, for example, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, or oleyl alcohol, but is not limited thereto. Thetobacco rod 21 may also include other additives, such as, for example, a flavoring agent, a wetting agent, and/or an organic acid. In addition, thetobacco rod 21 may include a flavoring liquid such as menthol or a moisturizing agent that is added as being sprayed onto thetobacco rod 21. - The
tobacco rod 21 may be manufactured in various forms. For example, thetobacco rod 21 may be manufactured as a sheet or as a strand. Thetobacco rod 21 may also be formed with a cut tobacco filler from finely cut tobacco sheets. In addition, thetobacco rod 21 may be enveloped by a heat-conductive material. The heat-conductive material may be, for example, a metal foil such as an aluminum foil, but is not limited thereto. For example, the heat-conductive material enveloping thetobacco rod 21 may evenly distribute the heat transferred to thetobacco rod 21 to improve the thermal conductivity to be applied to thetobacco rod 21, thereby improving the taste of tobacco. In addition, the heat-conductive material enveloping thetobacco rod 21 may function as a susceptor heated by an inductive heater. In this case, thetobacco rod 21 may further include a susceptor in addition to the heat-conductive material enveloping the outside thereof. - The
filter rod 22 may be a cellulose acetate filter. However, there is no limit to the shape of thefilter rod 22. For example, thefilter rod 22 may be a cylindrical rod, or a tubular rod including a hollow therein. Thefilter rod 22 may also be a recess-type rod. For example, when thefilter rod 22 includes a plurality of segments, at least one of the segments may be manufactured in a different shape. - In this example, a first segment of the
filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tubular structure including a hollow therein. In this example, the first segment may prevent internal materials of thetobacco rod 21 from being pushed back when theheater 13 is inserted and generate an aerosol cooling effect. A diameter of the hollow included in the first segment may be adopted from a range of 2 mm to 4.5 mm, but is not limited thereto. - A length of the first segment may be adopted from a range of 4 mm to 30 mm, but is not limited thereto. The length of the first segment may be 10 mm, but is not limited thereto.
- The first segment may have a hardness that is adjustable through an adjustment of the content of a plasticizer in a process of manufacturing the first segment. In addition, the first segment may be manufactured by inserting a structure such as a film or a tube of the same or different materials inside (e.g., the hollow).
- A second segment of the
filter rod 22 may cool an aerosol generated as theheater 13 heats thetobacco rod 21. The user may thus inhale the aerosol cooled down to a suitable temperature. - A length or diameter of the second segment may be determined in various ways according to the shape of the
cigarette 2. For example, a length of the second segment may be adopted from a range of 7 mm to 20 mm. For example, the length of the second segment may be approximately 14 mm, but is not limited thereto. - The second segment may be manufactured by weaving polymer fiber. In this case, a flavoring liquid may be applied to fiber formed of a polymer. Alternatively, the second segment may be manufactured by weaving a separate fiber to which a flavoring liquid is applied and the fiber formed of the polymer together. Alternatively, the second segment may be formed with a crimped polymer sheet.
- For example, the polymer may be prepared with 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 with the woven polymer fiber or the crimped polymer sheet, the second segment may include a single channel or a plurality of channels extending in a longitudinal direction. A channel used herein may refer to a path through which a gas (e.g., air or aerosol) passes.
- For example, the second segment formed with the crimped polymer sheet may be formed of a material having a thickness between approximately 5 m and approximately 300 μm, for example, between approximately 10 m and approximately 250 m. In addition, a total surface area of the second segment may be between approximately 300 mm2/mm and approximately 1000 mm2/mm. Further, an aerosol cooling element may be formed from a material having a specific surface area between approximately 10 mm2/mg and approximately 100 mm2/mg.
- The second segment may include a thread containing a volatile flavor ingredient. The volatile flavor ingredient may be menthol, but is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide at least 1.5 milligrams (mg) of menthol to the second segment.
- A third segment of the
filter rod 22 may be a cellulose acetate filter. A length of the third segment may be adopted from a range of 4 mm to 20 mm. For example, the length of the third segment may be approximately 12 mm, but is not limited thereto. - The third segment may be manufactured such that a flavor is generated by spraying a flavoring liquid onto the third segment in a process of manufacturing the third segment. Alternatively, a separate fiber to which the flavoring liquid is applied may be inserted into the third segment. An aerosol generated in the
tobacco rod 21 may be cooled as it passes through the second segment of thefilter rod 22, and the cooled aerosol may pass through the third segment into the user. Accordingly, when a flavoring element is added to the third segment, the durability of the flavor to be carried to the user may be enhanced. - In addition, the
filter rod 22 may include at least onecapsule 23. Thecapsule 23 may perform a function of generating a flavor, or a function of generating an aerosol. For example, thecapsule 23 may be of a structure in which a liquid containing a fragrance is wrapped with a film. Thecapsule 23 may have a spherical or cylindrical shape, but is not limited thereto. - Referring to
FIG. 10 , acigarette 3 may further include afront end plug 33. The front end plug 33 may be disposed on one side of atobacco rod 31 opposite to afilter rod 32. The front end plug 33 may prevent thetobacco rod 31 from escaping to the outside, and may also prevent an aerosol liquefied from thetobacco rod 31 during smoking from flowing into an aerosol-generating device (e.g., the aerosol-generatingdevice 1 ofFIGS. 6 through 8 ). - The
filter rod 32 may include afirst segment 32 a and asecond segment 32 b. Thefirst segment 32 a may correspond to the first segment of thefilter rod 22 ofFIG. 9 , and thesecond segment 32 b may correspond to the third segment of thefilter rod 22 ofFIG. 9 . - A diameter and a total length of the
cigarette 3 may correspond to the diameter and the total length of thecigarette 2 ofFIG. 9 . For example, a length of the front end plug 33 may be approximately 7 mm, a length of thetobacco rod 31 may be approximately 15 mm, a length of thefirst segment 32 a may be approximately 12 mm, and a length of thesecond segment 32 b may be approximately 14 mm. However, examples are not limited thereto. - The
cigarette 3 may be wrapped with at least onewrapper 35. Thewrapper 35 may have at least one hole through which external air flows inside or internal gas flows outside. For example, the front end plug 33 may be wrapped with afirst wrapper 35 a, thetobacco rod 31 may be wrapped with asecond wrapper 35 b, thefirst segment 32 a may be wrapped with athird wrapper 35 c, and thesecond segment 32 b may be wrapped with afourth wrapper 35 d. In addition, thecigarette 3 may be entirely wrapped again with afifth wrapper 35 e. - In addition, at least one
perforation 36 may be formed on thefifth wrapper 35 e. For example, theperforation 36 may be formed in an area surrounding thetobacco rod 31, but is not limited thereto. Theperforation 36 may perform a function of transferring heat generated by theheater 13 shown inFIGS. 7 and 8 to the inside of thetobacco rod 31. - In addition, the
second segment 32 b may include at least onecapsule 34. Thecapsule 34 may perform a function of generating a flavor or a function of generating an aerosol. For example, thecapsule 34 may have a structure in which a liquid containing a fragrance is wrapped with a film. Thecapsule 34 may have a spherical or cylindrical shape, but is not limited thereto. - The
first wrapper 35 a may be a combination of general filter wrapping paper and a metal foil such as an aluminum foil. For example, a total thickness of thefirst wrapper 35 a may be in a range of 45 μm to 55 μm, and may be 50.3 m. In addition, a thickness of the metal foil of thefirst wrapper 35 a may be in a range of 6 μm to 7 μm, and may be 6.3 μm. In addition, a basis weight of thefirst wrapper 35 a may be in a range of 50 g/m2 to 55 g/m2, and may be 53 g/m2. - The
second wrapper 35 b and thethird wrapper 35 c may be formed with general filter wrapping paper. Thesecond wrapper 35 b and thethird wrapper 35 c may each be, for example, porous wrapping paper or non-porous wrapping paper. - For example, the porosity of the
second wrapper 35 b may be 35000 CU, but is not limited thereto. In addition, a thickness of thesecond wrapper 35 b may be in a range of 70 μm to 80 μm, and may be 78 μm. In addition, a basis weight of thesecond wrapper 35 b may be in a range of 20 g/m2 to 25 g/m2, and may be 23.5 g/m2. - For example, the porosity of the
third wrapper 35 c may be 24000 CU, but is not limited thereto. In addition, a thickness of thethird wrapper 35 c may be in a range of 60 μm to 70 μm, and may be 68 μm. In addition, a basis weight of thethird wrapper 35 c may be in a range of 20 g/m2 to 25 g/m2, and may be 21 g/m2. - The
fourth wrapper 35 d may be formed with polylactic acid (PLA) laminated paper. The PLA laminated paper may refer to three-ply paper including a paper layer, a PLA layer, and a paper layer. For example, a thickness of thefourth wrapper 35 d may be in a range of 100 μm to 120 μm, and may be 110 μm. In addition, a basis weight of thefourth wrapper 35 d may be in a range of 80 g/m2 to 100 g/m2, and may be 88 g/m2. - The
fifth wrapper 35 e may be formed of sterile paper (e.g., MFW). The sterile paper (MFW) may refer to paper specially prepared such that it has enhanced tensile strength, water resistance, smoothness, or the like, compared to general paper. For example, a basis weight of thefifth wrapper 35 e may be in a range of 57 g/m2 to 63 g/m2, and may be 60 g/m2. In addition, a thickness of thefifth wrapper 35 e may be in a range of 64 μm to 70 μm, and may be 67 μm. - The
