[0026] 1A to 1C are diagrams illustrating an electronic device according to an example.

[0027] 1A and 1B, the electronic device 100 is composed of a front housing 110 including a display 120, an upper housing 130, a lower housing 140, and a rear housing 150. Each housing is fastened mechanically or magnetically, and various shapes of the electronic device 100 and methods of connecting each housing may be implemented. The electronic device 100 may include a circuit for performing an operation within the housing. For example, the circuit for performing an operation may be implemented on a printed circuit board (PCB), and the printed circuit board may be mounted within the housing.

[0028] According to one embodiment, the display 120 included in the front housing 110 displays a screen and receives user input. The user input may be one of button input and touch input. The display 120 may include at least one of mechanical buttons and a touch panel to receive the user input. While FIGS. 1A and 1B show the display 120 attached to the exterior of the front housing 110, the display 120 is not limited to the illustrated embodiment and may be attached to any location on each housing.

[0029] 1B, the upper housing 130 may include a hole for inserting a cigarette. The hole may have a variety of configurations depending on the type of cigarette. According to one embodiment, the upper housing 130 may be provided with a sensor for detecting the type of cigarette inserted.

[0030] According to one embodiment, the lower housing 140 includes a hole for connecting a power terminal for power supply. The electronic device 100 receives power from an external power source connected to the power terminal. The power terminal may be implemented as a USB port (e.g., USB C-type), but is not limited to the described embodiment and may be implemented in various forms. According to one embodiment, the power terminal hole or the power terminal of the lower housing 140 may include a sensor that can detect whether the terminal of the external power source is connected.

[0031] According to one embodiment, the electronic device 100 may be an electronic device for generating an aerosol. For example, the electronic device 100 includes a heating unit that receives power from a power source, such as a battery, to heat an aerosol-generating substrate of a cigarette disposed within the insert. The aerosol-generating substrate heated by the heating unit generates an aerosol. The specific configuration of the electronic device 100 will be described in detail with reference to Figures 2 and 3.

[0032] 1C, electronic device 100 may generate an aerosol by heating an aerosol-generating substrate within a cigarette 2 inserted into electronic device 100. A user may smoke by inhaling the generated aerosol. Electronic device 100 may heat the aerosol-generating substrate in a variety of ways.

[0033] According to one embodiment, the heating method of the electronic device 100 may be a method in which a heating unit directly applies heat to the aerosol-generating substrate.

[0034] According to another embodiment, the heating method of the electronic device 100 may be an induction heating method that does not directly apply heat to the aerosol-generating substrate. For example, the aerosol-generating substrate may be heated based on an electromagnetic field generated by resonating microwaves, as in a microwave oven.

[0035] Referring to FIG. 1C , the cigarette 2 is divided into a first portion including an aerosol-generating substrate and a second portion including a filter or the like. Alternatively, the second portion of the cigarette 2 may also include an aerosol-generating substrate. The entire first portion may be inserted into the electronic device 100, and the second portion may be exposed to the outside. Alternatively, only a portion of the first portion may be inserted into the electronic device 100, or the entire first portion and a portion of the second portion may be inserted. A user can inhale aerosol while chewing the second portion in their mouth. Here, the aerosol is generated when external air passes through the first portion, and the generated aerosol is delivered to the user's mouth through the second portion.

[0036] FIG. 2 is a configuration diagram of an electronic device according to an embodiment.

[0037] According to one embodiment, the electronic device 100 includes a control unit 210, a display unit 220, a battery 230, a heating unit 240, and an insertion unit 250. The electronic device 100 may further include general-purpose components. For example, the electronic device 100 may further include at least one sensor (such as a puff detection sensor, a temperature detection sensor, a cigarette insertion detection sensor, a power terminal detection sensor, etc.) and a motor for outputting tactile information and / or feedback. As described above with reference to FIGS. 1A to 1C, the electronic device 100 may be manufactured with a structure that allows external air to flow in and internal gas to flow out even when a cigarette 2 is inserted.

[0038] External air flows in through at least one air passage formed in the electronic device 100. For example, the opening and / or size of the air passage formed in the electronic device 100 may be adjusted by the user. This allows the user to adjust the amount of atomization, smoking sensation, etc. As another example, external air may flow into the cigarette 2 through at least one hole formed in the surface of the cigarette 2.

[0039] According to one embodiment, the electronic device 100 may be configured in a system with a separate cradle. For example, the cradle may be used to charge the battery of the electronic device 100.

[0040] The control unit 210 controls the operation of the electronic device 100. The control unit 210 will be described in detail below with reference to FIG.

[0041] The display unit 220 outputs visual information via the display 120 described with reference to Figures 1A to 1C and receives user input, which may be either a button input or a touch input.

[0042] The battery 230 supplies power to the electronic device 100. Power is supplied to the battery 230 from an external power supply source. For example, as described with reference to FIGS. 1A to 1C, the lower housing 140 includes a hole for a power terminal, and power is supplied from the external power supply source to charge the battery 230.

[0043] The heating element 240 heats the aerosol-forming substrate of a cigarette disposed within the insert 250. As discussed above with reference to Figure 1C, the heating element 240 may heat the aerosol-forming substrate in a variety of ways.

[0044] According to one embodiment, various types of cigarettes 2 are inserted into the insertion portion 250. The cigarettes 2 may be of a cut tobacco type shaped like a cigarette that is lit and smoked directly, a granular type in which aerosol-forming material in the form of granules or capsules is inserted into the cigarette, or a liquid type containing a liquid composition. Liquid-type cigarettes may be manufactured in a stick shape and contain a liquid containing a tobacco-containing substance including volatile tobacco flavor components or a liquid containing a non-tobacco substance within the stick.

[0045] According to one embodiment, the cigarette 2 is inserted into the insert 250 so that it surrounds at least a portion of the cigarette 2 (e.g., an aerosol-forming substrate), and the aerosol-forming substrate is heated by the heating element 240. For example, the cigarette 2 may be divided into a first portion including an aerosol-forming substrate and a second portion including a filter or the like. Alternatively, the second portion of the cigarette 2 may also include an aerosol-forming substrate.

[0046] The entire first portion may be inserted into the electronic device 100, and the second portion may be exposed to the outside. Alternatively, only a portion of the first portion may be inserted into the electronic device 100, or the entire first portion and a portion of the second portion may be inserted. A user may inhale the aerosol while biting the second portion. Here, the aerosol is generated by external air passing through the first portion, and the generated aerosol passes through the second portion and is delivered to the user's mouth.

[0047] According to an embodiment, the electronic device 100 may further include a communication module including a Bluetooth chip or a Wi-Fi chip, and the control unit 210 may communicate with an external device, such as a server, via a network using the communication module. If a hub device, such as an access point (AP), is present near the electronic device 100, the control unit 210 may communicate with the server via the hub device.

[0048] For example, heating profiles for cigarettes may be stored on an external server, and heating profiles for each type of cigarette may be transmitted from the external server to the electronic device 100 upon request by the electronic device 100 .

[0049] FIG. 3 is a configuration diagram of a control unit according to an embodiment.

[0050] According to one aspect, the control unit 210 includes a communication unit 310 , a processor 320 and a memory 330 .

[0051] The communication unit 310 is connected to the processor 320 and the memory 330 to transmit and receive data. The communication unit 310 can also be connected to other external devices to transmit and receive data. Hereinafter, the expression "transmitting and receiving A" refers to transmitting and receiving "information or data indicating A."

[0052] The communication unit 310 may be implemented as a circuit network within the control unit 210. For example, the communication unit 310 may include an internal bus and an external bus. As another example, the communication unit 310 may be an element that connects the control unit 210 to an external device. The communication unit 310 may be an interface. The communication unit 310 can receive data from an external device and transmit the data to the processor 320 and the memory 330.

[0053] The processor 320 processes data received by the communication unit 310 and data stored in the memory 330. A "processor" may be a data processing device implemented in hardware having circuits with physical structures for performing operations. For example, the operations may include code or instructions included in a program. For example, a data processing device implemented in hardware may include a microprocessor, a central processing unit, a processor core, a multi-core processor, a multiprocessor, an application-specific integrated circuit (ASIC), or a field programmable gate array (FPGA).

[0054] Processor 320 executes computer-readable code (eg, software) stored in a memory (eg, memory 330) and instructions triggered by processor 320.

[0055] The memory 330 stores data received by the communication unit 310 and data processed by the processor 320. For example, the memory 330 may store a program (or an application, software). The stored program may be coded to control the electronic device 100 and may be a set of syntax executable by the processor 320.

[0056] According to one embodiment, memory 330 may include one or more of volatile memory, non-volatile memory, random access memory (RAM), flash memory, a hard disk drive, and an optical disk drive.

[0057] The memory 330 stores a set of instructions (for example, software) that operate the control unit 210. The set of instructions that operate the control unit 210 is executed by the processor 320.

[0058] The communication unit 310, the processor 320, and the memory 330 are described in detail below with reference to FIGS. 4A-5.

[0059] 4A and 4B are screens displayed on an electronic device according to an example.

[0060] According to one embodiment, the processor 320 described above with reference to Figure 3 is capable of detecting the insertion of a cigarette 2 into the insert 250. According to another embodiment, the insert 250 (or a portion adjacent to the insert 250) may further include a sensor for detecting the type of cigarette 2, and the processor 320 may detect not only the insertion of a cigarette but also the type of cigarette 2 inserted via the sensor.

[0061] The processor 320 displays icons for cigarette types that can be supported by the electronic device 100 via the display unit 220. According to one embodiment, supported cigarette types may include cut tobacco, granules, and liquid phase, but are not limited to the described embodiment and may be implemented in various ways. For example, the processor 320 may display different icons for cigarettes with different heating profiles that include information regarding the appropriate heating temperature and heating time.

[0062] 4A shows a basic screen displayed on the display 120 of the electronic device 100. The basic screen may display an icon 410 for setting usage of the electronic device 100, an icon 420 for setting communication status (e.g., Bluetooth status), and an icon 430 for checking battery information. The basic screen may also display time information 440 and weather information 450. When a user tabs (or touches) the icon 410 for setting usage, settings for heating the heating unit 240 may be displayed as shown in FIG. 4B.

[0063] Referring to Figure 4B, the display 120 of the electronic device 100 illustrates a screen for configuring the heating element 240. According to an embodiment, the screen of Figure 4B is displayed when the insertion of a cigarette 2 is detected. According to another embodiment, the screen of Figure 4B is displayed via a user input 415 to the usage settings icon 410 on the basic screen shown in Figure 4A after the user inserts a cigarette 2 for heating the aerosol-generating substrate.

[0064] Referring to Figure 4B, icons 471, 474, and 477 are displayed for cigarette types that can be supported by electronic device 100. As shown in Figure 4B, icon 471 for a cut tobacco type, icon 474 for a granule type, and icon 477 for a liquid phase type are displayed on the screen, but this is not limited to the above-described embodiment, and various icons may be displayed for cigarettes with different heating profiles. In addition to the icons for cigarette types that can be supported, time information 460 and the like may also be displayed on the screen.

[0065] According to one embodiment, when processor 320 detects the type of cigarette 2 via a cigarette type detection sensor included in insertion portion 250, other visual effects may be applied to the icon corresponding to the detected cigarette type. For example, if processor 320 detects that the inserted cigarette is a cut tobacco type, it may display icon 471 for the cut tobacco type in a different background color from the background colors of the other icons 474, 477, or may display a message such as "Cut tobacco type is currently inserted."

[0066] According to one embodiment, in addition to the basic settings for cut tobacco type, granule type, and liquid phase type as shown in Figure 4B, a user can set a desired optimum heating temperature and optimum heating time to create a new heating profile, and an icon corresponding to the newly created heating profile may also be displayed. The user may also set a name for the newly created heating profile.

[0067] According to one embodiment, a user may swipe up or down the list of heating profiles to review cigarette types (or heating profiles), mark frequently used types as "favorites," or delete unused types.

[0068] When the user selects a type of cigarette, processor 320 can determine a corresponding heating profile and heat the aerosol-generating substrate of the inserted cigarette based on the determined heating profile. For example, if the user selects icon 471 for a cut tobacco type from the icons shown on display 120, processor 320 can determine a heating profile corresponding to the cut tobacco type and heat the aerosol-generating substrate of the cigarette in insertion portion 250 via heating portion 240 based on the heating profile.

[0069] The heating profile may include a preset appropriate heating time and / or appropriate heating temperature for each cigarette type, and the processor 320 may determine the heating profile corresponding to the cigarette type for which the user input was received by referring to the heating profile information stored in the memory 330. According to another embodiment, the heating profile information may be stored on an external server, and the processor 320 may obtain the heating profile information by requesting the heating profile corresponding to the cigarette type for which the user input was received from the external server via the communication unit 310.

[0070] The processor 320 may heat the aerosol-forming substrate of the cigarette in the insert 250 via the heating section 240 at an appropriate heating temperature and for an appropriate heating time based on the heating profile.

[0071] FIG. 5 is a flow chart of an aerosol-generating substrate heating method according to one embodiment.

[0072] The following steps S510 to S540 are performed by the processor 320 of the electronic device 100 described above with reference to FIGS. 1 to 4B, and redundant description will be omitted.

[0073] In step S510, the processor 320 detects the insertion of the cigarette 2. The processor 320 detects the insertion of the cigarette 2 via a sensor included within the insert 250. According to one embodiment, if the insert 250 includes a sensor capable of detecting the type of cigarette 2, the processor 320 may detect the cigarette type simultaneously with the insertion of the cigarette 2.

[0074] In step S520, processor 320 displays icons for the supported cigarette types. As described above with reference to Figure 4B, if processor 320 detects the type of cigarette 2 in step S510, it may apply a visual effect to the icon corresponding to the detected type of cigarette 2 that distinguishes it from other icons.

[0075] In step S530, the processor 320 determines a corresponding heating profile based on the user input for the type of cigarette 2. The heating profile information is stored in the memory 330 and can be obtained by request from an external server via the communication unit 310.

[0076] In step S540, the processor 320 heats the aerosol-generating substrate of the cigarette 2 based on the determined heating profile. For example, the processor 320 may heat the aerosol-generating substrate of the cigarette 2 in the insertion portion 250 via the heating section 240 based on the appropriate heating temperature and appropriate heating time of the heating profile. The user can inhale the aerosol generated by the heating of the aerosol-generating substrate through the cigarette 2.

[0077] 6-8 show one or more embodiments of an aerosol generating device with a cigarette inserted therein.

[0078] 6 to 8 described below, the aerosol generation device 1 corresponds to the electronic device 100 described above with reference to FIGS. 1A to 2. The battery 11 corresponds to the battery 230 described above with reference to FIG. 2. The control unit 12 corresponds to the control unit 210 described above with reference to FIG. 2. The vaporizer 14 or heater 13 corresponds to the heating unit 240 described above with reference to FIG. 2.

[0079] 6, the aerosol generation device 1 includes a battery 11, a control unit 12, and a heater 13. Referring to FIGS. 7 and 8, the aerosol generation device 1 further includes a vaporizer 14. A cigarette 2 may be inserted into the internal space of the aerosol generation device 1.

[0080] The components related to this embodiment are illustrated in the aerosol-generating device 1 shown in Figures 6 to 8. Therefore, it will be understood by a person having ordinary skill in the technical field related to this embodiment that the aerosol-generating device 1 further includes general-purpose components in addition to the components shown in Figures 6 to 8.

[0081] 7 and 8 show that the aerosol generating device 1 includes the heater 13, but the heater 13 may be omitted if necessary.

[0082] Fig. 6 illustrates that the battery 11, the control unit 12, and the heater 13 are arranged in a row. Fig. 7 illustrates that the battery 11, the control unit 12, the vaporizer 14, and the heater 13 are arranged in a row. Fig. 8 illustrates that the vaporizer 14 and the heater 13 are arranged in parallel. However, the internal structure of the aerosol generation device 1 is not limited to those shown in Figs. 6 to 8. That is, the arrangement of the battery 11, the control unit 12, the heater 13, and the vaporizer 14 can be changed depending on the design of the aerosol generation device 1.

[0083] When a cigarette 2 is inserted into the aerosol generating device 1, the aerosol generating device 1 can activate the heater 13 and / or vaporizer 14 to generate an aerosol. The aerosol generated by the heater 13 and / or vaporizer 14 passes through the cigarette 2 and is transmitted to the user.

[0084] If desired, the aerosol generating device 1 can heat the heater 13 even when no cigarette 2 is inserted in the aerosol generating device 1 .

[0085] The battery 11 supplies power used to operate the aerosol generation device 1. For example, the battery 11 may supply power to heat the heater 13 or the vaporizer 14, and may also supply power necessary for the operation of the control unit 12. The battery 11 can also supply power necessary for the operation of a display, a sensor, a motor, etc., installed in the aerosol generation device 1.

[0086] The control unit 12 controls the overall operation of the aerosol generation device 1. Specifically, the control unit 12 controls the operation of not only the battery 11, the heater 13, and the vaporizer 14, but also other components included in the aerosol generation device 1. The control unit 12 may also check the state of each component of the aerosol generation device 1 to determine whether the aerosol generation device 1 is in an operable state.

[0087] The control unit 12 includes at least one processor. The processor may be implemented as an array of multiple logic gates, or as a combination of a general-purpose microprocessor and a memory storing a program executed by the microprocessor. Those skilled in the art will understand that the control unit 12 may also be implemented in other forms of hardware.

[0088] The heater 13 is heated by power supplied from the battery 11. For example, when the cigarette 2 is inserted into the aerosol generating device 1, the heater 13 is disposed outside the cigarette 2. Thus, the heated heater 13 can increase the temperature of the aerosol-generating substance within the cigarette 2.

[0089] The heater 13 may be an electric resistance heater. For example, the heater 13 includes an electric conductive track, and the heater 13 is heated by passing an electric current through the electric conductive track. However, the heater 13 is not limited to the above example, and may be any heater that can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generation device 1, or may be set to a desired temperature by the user.

[0090] Alternatively, in another example, the heater 13 may be an induction heater. Specifically, the heater 13 may include an electrically conductive coil for heating the cigarette 2 in an induction heating manner, and the cigarette 2 may include a susceptor that can be heated by the induction heater.

[0091] For example, the heater 13 may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and depending on the shape of the heating element, the interior or exterior of the cigarette 2 may be heated.

[0092] Furthermore, a plurality of heaters 13 may be arranged in the aerosol generation device 1. Here, the plurality of heaters 13 may be arranged so as to be inserted inside the cigarette 2, or may be arranged outside the cigarette 2. Furthermore, some of the plurality of heaters 13 may be arranged so as to be inserted inside the cigarette 2, and the rest may be arranged outside the cigarette 2. Furthermore, the shape of the heaters 13 is not limited to the shapes shown in Figures 6 to 8, and various shapes may be manufactured.

[0093] The vaporizer 14 heats the liquid-phase composition to generate an aerosol, which can be transmitted to the user through the cigarette 2. In other words, the aerosol generated by the vaporizer 14 travels along an airflow passage in the aerosol generating device 1, and the airflow passage is configured to allow the aerosol generated by the vaporizer 14 to be transmitted to the user through the cigarette 2.

[0094] For example, the vaporizer 14 may include, but is not limited to, a liquid storage unit, a liquid transfer means, and a heating element. For example, the liquid storage unit, the liquid transfer means, and the heating element may be included in the aerosol generation device 1 as independent modules.

[0095] The liquid storage unit may store a liquid-phase composition. For example, the liquid-phase composition may be a liquid containing a tobacco-containing substance including a volatile tobacco aroma component, or a liquid containing a non-tobacco substance. The liquid storage unit may be manufactured so as to be detachable / attachable to the vaporizer 14, or may be manufactured integrally with the vaporizer 14.

[0096] For example, the liquid phase composition may contain water, solvent, ethanol, plant extract, fragrance, flavoring, or vitamin mixture. Flavorings include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. Flavorings may include components that can provide various flavors or tastes to the user. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid phase composition may also contain an aerosol-forming agent, such as glycerin and propylene glycol.

[0097] The liquid transfer means can transfer the liquid phase composition of the liquid storage portion to the heating element, and can be, for example, but not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0098] The heating element is an element for heating the liquid-phase composition transferred by the liquid transfer means. For example, the heating element may be, but is not limited to, a metal hot wire, a metal hot plate, a ceramic heater, or the like. The heating element may also be made of a conductive filament such as a nichrome wire, and may be configured to be wound around the liquid transfer means. The heating element is heated by supplying an electric current, and transfers heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.

[0099] For example, the vaporizer 14 may be referred to as, but is not limited to, a cartomizer or an atomizer.

[0100] Meanwhile, the aerosol generation 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 generation device 1 may include a display capable of outputting visual information and / or a motor for outputting tactile information. The aerosol generation device 1 may also include at least one sensor (such as a puff detection sensor, a temperature detection sensor, or a cigarette insertion detection sensor). The aerosol generation device 1 may also be manufactured with a structure that allows external air to flow in and internal gas to flow out even when a cigarette 2 is inserted.

[0101] According to one embodiment, the aerosol generation device 1 may form a system together with a separate cradle. For example, the cradle may be used to charge the battery 11 of the aerosol generation device 1. Alternatively, the heater 13 may heat the aerosol generation device 1 while the cradle and the aerosol generation device 1 are coupled together.

[0102] The cigarette 2 is similar to a typical combustible cigarette. For example, the cigarette 2 is divided into a first portion containing an aerosol-forming material and a second portion containing a filter or the like. Alternatively, the second portion of the cigarette 2 may also contain an aerosol-forming material. For example, the aerosol-forming material in the form of granules or capsules may be inserted into the second portion.

[0103] The entire first part may be inserted into the aerosol generation 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 aerosol generation device 1, or the entire first part and a part of the second part may be inserted. A user can inhale the aerosol while biting the second part in their mouth. Here, the aerosol is generated by external air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

[0104] As one example, external air may flow in through at least one air passage formed in the aerosol generation device 1. For example, the opening and / or closing of the air passage formed in the aerosol generation device 1 and / or the size of the air passage may be adjusted by the user. This allows the amount of spray, smoking sensation, etc. to be adjusted according to the user. As another example, external air may flow into the cigarette 2 through at least one hole formed in the surface of the cigarette 2.

[0105] 9 and 10, an example of a cigarette 2 will now be described.

[0106] 9 and 10 are diagrams showing examples of cigarettes according to an embodiment.

[0107] The cigarette 2 of Figures 9 and 10 may be the cigarette 2 previously described with reference to Figure 1C.

[0108] 9, the cigarette 2 includes a tobacco rod 21 and a filter rod 22. The first portion 21 described above with reference to FIGS. 6 to 8 includes the tobacco rod 21, and the second portion 22 includes the filter rod 22.

[0109] Although the filter rod 22 is illustrated as a single segment in Figure 9, this is not limiting. In other words, the filter rod 22 may be composed of multiple segments. For example, the filter rod 22 may include a segment that cools the aerosol and a segment that filters a predetermined component contained in the aerosol. Furthermore, the filter rod 22 may further include at least one segment that performs another function, as needed.

[0110] The cigarette 2 may have a diameter within the range of 5 mm to 9 mm and a length of approximately 48 mm, but is not limited thereto. For example, the tobacco rod 21 may have a length of approximately 12 mm, the first segment of the filter rod 22 may have a length of approximately 10 mm, the second segment of the filter rod 22 may have a length of approximately 14 mm, and the third segment of the filter rod 22 may have a length of approximately 12 mm, but is not limited thereto.

[0111] The cigarette 2 may be wrapped in at least one wrapper 24. The wrapper 24 may have at least one hole formed therein to allow external air to enter and internal gas to escape. As one example, the cigarette 2 may be wrapped in a single wrapper 24. As another example, the cigarette 2 may be wrapped in two or more wrappers 24 in a redundant manner. For example, the tobacco rod 21 may be wrapped in a first wrapper 24a, and the filter rod 22 may be wrapped in wrappers 24b, 24c, and 24d. The entire cigarette 2 may then be rewrapped in a single wrapper 24e. If the filter rod 22 is composed of multiple segments, each segment may be wrapped in a wrapper 24b, 24c, or 24d.

[0112] The first wrapper 24a and the second wrapper 24b may be made of a typical filter wrapping paper. For example, the first wrapper 24a and the second wrapper 24b may be made of porous wrapping paper or non-porous wrapping paper. The first wrapper 24a and the second wrapper 24b may also be made of oil-resistant paper and / or aluminum-clad paper wrapping material.

[0113] The third wrapper 24c may be made into a hard wrapping paper. For example, the basis weight of the third wrapper 24c is 88 g / m 2 ~96g / m 2 Within the range of 90 g / m 2 ~94g / m 2 The thickness of the third wrapper 24c may be within the range of 120 um to 130 um, and may be 125 um.

[0114] The fourth wrapper 24d may be made of a grease-resistant hard wrapping paper. For example, the basis weight of the fourth wrapper 24d is 88 g / m 2 ~96g / m 2 Within the range of 90 g / m 2 ~94g / m 2 The thickness of the fourth wrapper 24d may be within the range of 120 um to 130 um, and may be 125 um.

[0115] The fifth wrapper 24e may be made of a sterilized paper (MFW). Here, sterilized paper (MFW) refers to 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 24e is 57 g / m 2 ~63g / m 2 Within the range of 60 g / m 2 The thickness of the fifth wrapper 24e is in the range of 64 um to 70 um, and may be 67 um.

[0116] The fifth wrapper 24e has a predetermined substance added thereto. Examples of the predetermined substance include, but are not limited to, silicon. For example, silicon has properties such as heat resistance (i.e., little change with temperature), internal oxidation resistance, resistance to various chemicals, water repellency, and electrical insulation. However, any substance other than silicon that has the above-mentioned properties can be applied (or coated) to the fifth wrapper 24e without any restrictions.

[0117] The fifth wrapper 24e can prevent the cigarette 2 from burning. For example, if the tobacco rod 21 is heated by the heater 13, the cigarette 2 may burn. Specifically, if the temperature of the tobacco rod 21 rises above the ignition point of any one of the substances contained in the tobacco rod 21, the cigarette 2 will burn. Even in such a case, the fifth wrapper 24e can prevent the cigarette 2 from burning because it contains a non-combustible substance.

[0118] Furthermore, the fifth wrapper 24e can prevent contamination of the holder 1 by substances produced in the cigarette 2. A liquid substance may be produced in the cigarette 2 when the user puffs. For example, a liquid substance (e.g., moisture) is produced when an aerosol produced in the cigarette 2 is cooled by external air. By wrapping the cigarette 2 with the fifth wrapper 24e, the liquid substance produced in the cigarette 2 can be prevented from leaking out of the cigarette 2.

[0119] The tobacco rod 21 contains an aerosol-forming material. For example, the aerosol-forming material 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. The tobacco rod 21 may also contain other additives, such as flavoring agents, humectants, and / or organic acids. A flavoring liquid, such as menthol or a humectant, may also be added to the tobacco rod 21 by spraying it onto the tobacco rod 21.

[0120] The tobacco rod 21 can be manufactured in various ways. For example, the tobacco rod 21 can be manufactured in a sheet or a strand. The first segment 21 can also be manufactured from shredded tobacco, which is a tobacco sheet. The first segment 21 can also be surrounded by a thermally conductive material. For example, the thermally conductive material can be a metal foil such as aluminum foil, but is not limited to this. For example, the thermally conductive material surrounding the tobacco rod 21 can evenly distribute heat transferred to the tobacco rod 21, improving the thermal conductivity of the tobacco rod and thereby improving the tobacco taste. The thermally conductive material surrounding the tobacco rod 21 can also function as a susceptor heated by an induction heater. Here, the tobacco rod 21 can further include a susceptor in addition to the thermally conductive material surrounding the exterior.

[0121] The filter rod 22 may be an acetyl cellulose filter. Meanwhile, the shape of the filter rod 22 is not limited. For example, the filter rod 22 may be a cylindrical rod or a tube-type rod with a hollow interior. The filter rod 22 may also be a reseated rod. If the filter rod 22 is composed of multiple segments, at least one of the multiple segments may be manufactured to have a different shape.

[0122] The first segment of the filter rod 22 may be an acetyl cellulose filter. For example, the first segment may be a tubular structure with a hollow interior. When the heater 13 is inserted through the first segment, it can prevent the internal material of the tobacco rod 21 from shifting backward and can also have a cooling effect on the aerosol. The diameter of the hollow interior of the first segment may be, but is not limited to, a diameter in the range of 2 mm to 4.5 mm.

[0123] The length of the first segment is within the range of 4 mm to 30 mm, but is not limited to this. The length of the first segment may be 10 mm, but is not limited to this.

[0124] The lightness of the first segment can be adjusted by adjusting the content of plasticizer during manufacturing of the first segment. The first segment may also be manufactured by inserting a structure such as a film or tube made of the same or different material inside (e.g., hollow).

[0125] The second segment of the filter rod 22 cools the aerosol generated by the heater 13 heating the tobacco rod 21. Thus, the user can inhale the aerosol that has been cooled to an appropriate temperature.

[0126] The length or diameter of the second segment may be determined in various ways depending on the form of the cigarette 2. For example, the length of the second segment may be in the range of 7 mm to 20 mm. For example, the length of the second segment may be about 14 mm, but is not limited to this.

[0127] The second segment may be produced by weaving polymer fibers. In this case, the fragrance liquid may be applied to the polymer fibers. Alternatively, the second segment may be produced by weaving a separate fiber coated with the fragrance liquid and a polymer fiber together. Alternatively, the second segment may be made of a wound polymer sheet.

[0128] For example, the polymer may 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.

[0129] When the second segment is formed from woven polymer fibers or a wound polymer sheet, the second segment may include one or more longitudinally extending channels, where channel refers to a passageway through which a gas (e.g., air or aerosol) passes.

[0130] For example, the second segment of wound polymer sheet may be formed from a material having a thickness between about 5 μm and about 300 μm, e.g., between about 10 μm and about 250 μm, and the total surface area of ​​the second segment is less than about 300 mm 2 / mm and approximately 1000mm 2 / mm. The aerosol cooling element may also have a specific surface area of ​​between about 10 mm 2 / mg and about 100mm 2 / mg of material.

[0131] The second segment may include a thread containing a volatile flavor component, which may be, but is not limited to, menthol. For example, the thread may be loaded with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0132] The third segment of the filter rod 22 may be an acetyl cellulose filter. The length of the third segment may be within the range of 4 mm to 20 mm. For example, the length of the third segment may be approximately 12 mm, but is not limited to this.

[0133] During the manufacturing process, the third segment may be manufactured so that a flavor is generated by spraying a flavoring liquid onto the third segment. Alternatively, separate fibers coated with a flavoring liquid may be inserted into the third segment. The aerosol generated in 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 via the third segment. Therefore, when a flavoring element is added to the third segment, the effect of enhancing the persistence of the flavor delivered to the user can be achieved.

[0134] The filter rod 22 may also include at least one capsule 23. The capsule 23 may function to generate a flavor or to generate an aerosol. For example, the capsule 23 may have a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 23 may have a spherical or cylindrical shape, but is not limited thereto.

[0135] Referring to Figure 10, the cigarette 3 may further include a shear plug 33. The shear plug 33 may be disposed on one side of the tobacco rod 31, facing the filter rod 32. The shear plug 33 prevents the tobacco rod 31 from detaching to the outside, and can prevent aerosol liquefied from the tobacco rod 31 during smoking from flowing into the aerosol generating device (e.g., 1 in Figures 6 to 8).

[0136] Filter rod 32 includes a first segment 32a and a second segment 32b, where first segment 32a corresponds to the first segment of filter rod 22 in Figure 9 and second segment 32b corresponds to the third segment of filter rod 22 in Figure 9.

[0137] The diameter and length of cigarette 3 are relative to the diameter and length of cigarette 2 shown in Figure 9. For example, but not limited to, the length of shear plug 33 may be about 7 mm, the length of tobacco rod 31 may be about 15 mm, the length of first segment 32a may be about 12 mm, and the length of second segment 32b may be about 14 mm.

[0138] The cigarette 3 may be wrapped in at least one wrapper 35. The wrapper 35 may have at least one hole formed therein to allow external air to enter or internal gas to escape. For example, the shear plug 33 may be wrapped in a first wrapper 35a, the tobacco rod 31 may be wrapped in a second wrapper 35b, the first segment 32a may be wrapped in a third wrapper 35c, and the second segment 32b may be wrapped in a fourth wrapper 35d. The entire cigarette 3 may then be rewrapped in a fifth wrapper 35e.

[0139] The fifth wrapper 35e may also have at least one perforation 36. For example, but not limited to, the perforation 36 may be formed in the area surrounding the tobacco rod 31. The perforation 36 serves to transfer heat generated by the heater 13 shown in Figures 7 and 8 to the interior of the tobacco rod 31.

[0140] The second segment 32b may also include at least one capsule 34. The capsule 34 may function to generate a flavor or may function to generate an aerosol. For example, the capsule 34 may have a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 34 may have a spherical or cylindrical shape, but is not limited thereto.

[0141] The first wrapper 35a is made by bonding a metal foil such as aluminum foil to a general filter wrapping paper. For example, the overall thickness of the first wrapper 35a is within a range of 45 μm to 55 μm, and may be 50.3 μm. The thickness of the metal foil of the first wrapper 35a is within a range of 6 μm to 7 μm, and may be 6.3 μm. The basis weight of the first wrapper 35a is 50 g / m 2 ~55g / m 2 falls within the range of 53 g / m 2 may be.

[0142] The second wrapper 35b and the third wrapper 35c may be made of a common filter wrapping paper, for example, the second wrapper 35b and the third wrapper 35c may be porous wrapping paper or non-porous wrapping paper.

[0143] For example, the porosity of the second wrapper 35b may be 35000 CU, but is not limited to this. The thickness of the second wrapper 35b is within the range of 70 um to 80 um, and may be 78 um. The basis weight of the second wrapper 35b is 20 g / m 2 ~25g / m 2 falls within the range of 23.5 g / m 2 may be.

[0144] For example, the porosity of the third wrapper 35c may be 24000 CU, but is not limited to this. The thickness of the third wrapper 35c is within the range of 60 um to 70 um, and may be 68 um. The basis weight of the third wrapper 35c is 20 g / m 2 ~25g / m 2 falls within the range of 21 g / m 2 may be.

[0145] The fourth wrapper 35d may be made of PLA laminate paper. Here, PLA laminate paper refers to a triple layer of paper including a paper layer, a PLA layer, and another paper layer. For example, the thickness of the fourth wrapper 35d is within the range of 100 μm to 120 μm, and may be 110 μm. The basis weight of the fourth wrapper 35d is 80 g / m2 ~100g / m 2 Within the range of 88g / m 2 may be.

[0146] The fifth wrapper 35e may be made of a sterilized paper (MFW). Here, sterilized paper (MFW) refers to 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 35e is 57 g / m 2 ~63g / m 2 Within the range of 60 g / m 2 The thickness of the fifth wrapper 35e is in the range of 64 um to 70 um, and may be 67 um.

[0147] The fifth wrapper 35e may be doped with a predetermined substance. Examples of the predetermined substance include, but are not limited to, silicon. For example, silicon has properties such as heat resistance (i.e., small changes due to temperature), internal oxidation resistance, resistance to various chemicals, water repellency, and electrical insulation. However, any substance other than silicon that has the above properties can be applied (or coated) to the fifth wrapper 35e without limitation.

[0148] The shear plug 33 may be made of cellulose acetate. As an example, the shear plug 33 may be made by adding a plasticizer (e.g., triacetin) to cellulose acetate tow. The mono-denier of the filaments constituting the cellulose acetate tow is within the range of 1.0 to 10.0, and may be within the range of 4.0 to 6.0. The mono-denier of the filaments constituting the shear plug 33 may be 5.0. The cross section of the filaments constituting the shear plug 33 may be Y-shaped. The total denier of the shear plug 33 is within the range of 20,000 to 30,000, and may be within the range of 25,000 to 30,000. For example, the total denier of the shear plug 33 may be 28,000.

[0149] Also, if desired, the shear plug 33 may include at least one channel, and the cross-sectional shape of the channel may be manufactured in a variety of ways.

[0150] The tobacco rod 31 corresponds to the tobacco rod 21 described above with reference to Figure 9. Therefore, a detailed description of the tobacco rod 31 will be omitted below.

[0151] The first segment 32a may be made of cellulose acetate. For example, the first segment may be a tube-shaped structure having a hollow interior. The first segment 32a may be made by adding a plasticizer (e.g., triacetin) to cellulose acetate tow. For example, the mono-denier and total denier of the first segment 32a may be the same as the mono-denier and total denier of the shear plug 33.

[0152] The second segment 32b may be made of acetyl cellulose. The mono-denier of the filaments constituting the second segment 32b is within the range of 1.0 to 10.0, and may be within the range of 8.0 to 10.0. For example, the mono-denier of the filaments of the second segment 32b may be 9.0. The cross section of the filaments of the second segment 32b may be Y-shaped. The total denier of the second segment 32b is within the range of 20,000 to 30,000, and may be 25,000.

[0153] FIG. 11 is a block diagram of an aerosol generating device 9 according to another embodiment.

However, the internal structure of the aerosol generation device 9 is not limited to that shown in Fig. 11. That is, a person skilled in the art related to this embodiment can understand that some of the components shown in Fig. 11 may be omitted or new components may be added depending on the design of the aerosol generation device 9.

[0156] The detection unit 92 can detect the state of the aerosol generation device 9 or the state around the aerosol generation device 9, and transmit the detected information to the control unit 91.

[0163] The display unit 93a can visually provide a user with information about the aerosol generation device 9. For example, the information about the aerosol generation device 9 means various information such as the charging / discharging status of the battery 94 of the aerosol generation device 9, the preheating status of the heater 95, the insertion / removal status of an aerosol product, or a status in which use of the aerosol generation device 9 is restricted (e.g., detection of an abnormal item), and the display unit 93a can output the information to the outside. The display unit 93a may be, for example, a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), or the like. Furthermore, the display unit 93a may be an LED light-emitting element.

For example, the haptic unit 93b includes a motor, a piezoelectric element, or an electrical stimulation device.

[0165] The acoustic output unit 93c audibly provides the user with information relating to the aerosol generation device 9. For example, the acoustic output unit 93c can convert an electric signal into an acoustic signal and output it to the outside.

[0166] The battery 94 supplies power used to operate the aerosol generation device 9. The battery 94 supplies power to enable the heater 95 to heat. The battery 94 can also supply power necessary for the operation of other components provided within the aerosol generation device 9 (e.g., the detection unit 92, the output unit 93, the user input unit 96, the memory 97, and the communication unit 98). The battery 94 may be a rechargeable battery or a disposable battery. For example, the battery 94 may be a lithium polymer (LiPoly) battery, but is not limited to this.

[0167] The heater 95 can heat the aerosol-generating material by receiving power from the battery 94. The aerosol generation device 9 may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of the battery 94 and supplies it to the heater 95. Furthermore, when the aerosol generation device 9 generates aerosol by an induction heating method, the aerosol generation device 9 further includes a DC / AC converter that converts the DC power supply of the battery 94 into AC power supply.

[0168] The control unit 91, the detection unit 92, the output unit 93, the user input unit 96, the memory 97, and the communication unit 98 can perform their functions by receiving power from a battery 94. The unit 91 further includes a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the battery 94 and supplies it to each of the components.

[0169] In one embodiment, the heater 95 may be formed from any suitable electrically resistive material, such as, but not limited to, a metal or metal alloy, including titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, etc. The heater 95 may also be implemented as, but not limited to, a metal hot wire, a metal hot plate having an electrically conductive track disposed thereon, a ceramic heating element, etc.

[0171] In one embodiment, heater 95 includes multiple heaters, for example, heater 95 includes a first heater for heating the cigarette and a second heater for heating the liquid phase.

[0172] The user input unit 96 can receive information input by a user and output information to a user.

[0177] The control unit 91 can control the overall operation of the aerosol generation device 9. In one embodiment, the control unit 91 includes at least one processor. The processor may be realized as an array of multiple logic gates, or may be realized as a combination of a general-purpose microprocessor and a memory in which a program that can be executed by the microprocessor is stored. Furthermore, it will be understood by those skilled in the art to which this embodiment pertains that the processor may be realized in other forms of hardware.

[0178] The control unit 91 can control the temperature of the heater 95 by controlling the supply of power from the battery 94 to the heater 95. For example, the control unit 91 can control the power supply by controlling the switching of a switching element between the battery 94 and the heater 95. In a different example, a heating direct circuit may control the power supply to the heater 95 in response to a control command from the control unit 91.

[0179] The control unit 91 analyzes the results detected by the detection unit 92 and controls the processes to be executed thereafter. For example, the control unit 91 can control the power supplied to the heater 95 so that the operation of the heater 95 starts or ends based on the results detected by the detection unit 92. As another example, the control unit 91 can control the amount of power supplied to the heater 95 and the time for which the power is supplied based on the results detected by the detection unit 92 so that the heater 95 can heat up to a predetermined temperature or maintain an appropriate temperature.

[0180] The control unit 91 controls the output unit 93 based on the result detected by the detection unit 92. For example, when the number of puffs counted via the puff sensor 92c reaches a preset number, the control unit 91 can notify the user via at least one of the display unit 93a, the haptic unit 93b, and the audio output unit 93c that the aerosol generation device 9 will immediately shut down.

[0181] In one embodiment, the control unit 91 can control the time and / or amount of power supplied to the heater 95 depending on the state of the aerosol-generating product detected by the detection unit 92. For example, if the aerosol-generating product 15 is in an overly humid state, the control unit 91 can control the time of power supply to the induction coil to increase the preheating time compared to when the aerosol-generating product is in a normal state.

[0182] The methods according to the present invention may be embodied in the form of program instructions that can be executed by various computer means and stored on a computer-readable storage medium. The storage medium may include program instructions, data files, data structures, and the like, alone or in combination. The storage medium and program instructions may be specially designed and constructed for the purposes of the present invention, or they may be well-known and available to those skilled in the art of computer software. Examples of computer-readable storage media include magnetic media such as hard disks, floppy disks, and magnetic tape, optical media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, and hardware devices specially configured to store and execute program instructions, such as ROM, RAM, and flash memory. Examples of program instructions include not only machine code, such as generated by a compiler, but also high-level language code executed by a computer using an interpreter, for example. The hardware devices described above may be configured to operate as one or more software modules to perform the operations described in the present invention, or vice versa.

[0183] Software includes computer programs, codes, instructions, or a combination of one or more thereof, which can configure a processing device to operate as desired or can independently or in combination instruct the processing device. The software and / or data can be permanently or temporarily embodied in any type of machine, component, physical device, virtual device, computer storage medium or device, or transmitted signal wave to be interpreted by the processing device or to provide instructions or data to the processing device. The software can be distributed across computer systems coupled to a network and stored and executed in a distributed manner. The software and data can be stored on one or more computer-readable recording media.
