[0027] FIG. 1 shows a system according to one embodiment.

[0028] According to one embodiment, the system 100 may include at least one of a user terminal 110, an electronic device 120, and a wearable device 130. For example, the system 100 may include all of the user terminal 110, the electronic device 120, and the wearable device 130.

[0031] According to one embodiment, the wearable device 130 may be an electronic device that can be worn on a part of the user's body. The wearable device 130 may be, for example, a smart watch and is not limited to the described embodiment.

[0032] A user may smoke by being provided with an aerosol generated by the electronic device 120. The electronic device 120 may be referred to as an aerosol generating device. For example, the electronic device 120 may generate an aerosol by applying heat to a cigarette inserted into the electronic device 120. As another example, the electronic device 120 may generate an aerosol using a substance in a liquid-type cartridge or a solid-type cartridge within the electronic device 120.

[0035] 2 to 4 are diagrams showing an example in which a cigarette is inserted into an electronic device according to an embodiment.

[0036] 2, the electronic device 1 includes a detection unit 10, a battery 11, a control unit 12, and a heater 13. With reference to FIGS. 3 and 4, the electronic device 1 further includes a vaporizer 14. A cigarette 2 may be inserted into the internal space of the electronic device 1. The electronic device 1 may be the electronic device 120 described above with reference to FIG.

[0037] According to an embodiment, the electronic device 1 may further include a display.

[0038] Components related to this embodiment are shown in the electronic device 1 shown in Figures 2 to 4. Therefore, a person having ordinary skill in the technical field related to this embodiment can understand that the electronic device 1 may further include other general-purpose components in addition to the components shown in Figures 2 to 4.

[0039] Additionally, although FIGS. 3 and 4 show electronic device 1 as including heater 13, heater 13 may be omitted if desired.

[0040] In Fig. 2, the detection unit 10, the battery 11, the control unit 12, and the heater 13 are shown to be arranged in a row. Also, in Fig. 3, the detection unit 10, the battery 11, the control unit 12, the vaporizer 14, and the heater 13 are shown to be arranged in a row. Furthermore, in Fig. 4, the vaporizer 14 and the heater 13 are shown to be arranged in parallel. However, the internal structure of the electronic device 1 is not limited to those shown in Figs. 2 to 4. In other words, the arrangement of the detection unit 10, the battery 11, the control unit 12, the heater 13, and the vaporizer 14 may be changed depending on the design of the electronic device 1.

[0041] When the cigarette 2 is inserted into the electronic device 1, the electronic 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 is transmitted through the cigarette 2 to the user.

[0042] If necessary, the electronic device 1 can heat the heater 13 even when no cigarette 2 is inserted in the electronic device 1 .

[0043] The battery 11 supplies power used for operating the electronic device 1. For example, the battery 11 can supply power to heat the heater 13 or the vaporizer 14, and can supply power necessary for the control unit 12 to operate. The battery 11 can also supply power necessary for the display, sensor, motor, and the like installed in the electronic device 1 to operate.

[0044] The control unit 12 generally controls the operation of the electronic device 1. Specifically, the control unit 12 controls the operation of not only the detection unit 10, the battery 11, the heater 13, and the vaporizer 14, but also other components included in the electronic device 1. The control unit 12 can also check the state of each component of the electronic device 1 to determine whether the electronic device 1 is in an operable state.

[0045] The control unit 12 includes at least one processor. The processor may be realized by an array of a plurality of logic gates, or may be realized by a combination of a general-purpose microprocessor and a memory storing a program that can be executed by the microprocessor. Those skilled in the art will understand that the processor may be realized by other types of hardware.

[0046] The heater 13 can be heated by power supplied from the battery 11. For example, the heater 13 can be located outside the cigarette when the cigarette is inserted into the electronic device 1. The heated heater 13 can thus increase the temperature of the aerosol-generating substance (or substrate) within the cigarette.

[0047] The heater 13 may be an electric resistive heater. For example, the heater 13 may include an electric conductive track, and the heater 13 may be 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 pre-set in the electronic device 1, or may be set by a user to a desired temperature. For example, the temperature of the heater 13 may be controlled based on a temperature profile. According to one embodiment, the temperature profile may be a profile of a target temperature change during an operating time. According to another embodiment, the temperature profile may be a profile of a current change provided during an operating time. The temperature of the heater 13 may change depending on the current change.

[0048] Meanwhile, as another example, the heater 13 may be an induction heater. Specifically, the heater 13 may include an electrically conductive coil for heating the cigarette in an induction heating manner, and the cigarette may include a susceptor that can be heated by the induction heater.

[0049] 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 the cigarette 2 depending on the shape of the heating element.

[0050] Furthermore, a plurality of heaters 13 may be disposed in the electronic device 1. In this case, the plurality of heaters 13 may be disposed so as to be inserted inside the cigarette 2, or may be disposed outside the cigarette 2. Furthermore, some of the plurality of heaters 13 may be disposed so as to be inserted inside the cigarette 2, and the rest may be disposed outside the cigarette 2. Furthermore, the shape of the heater 13 is not limited to the shapes shown in Figs. 2 to 4, and may be produced in various shapes.

[0051] The vaporizer 14 can heat the liquid composition to generate an aerosol, which can be transmitted through the cigarette 2 to the user. In other words, the aerosol generated by the vaporizer 14 can travel along an airflow passage of the electronic device 1, which can be configured to transmit the aerosol generated by the vaporizer 14 through the cigarette 2 to the user. For example, the temperature of the vaporizer 14 can be controlled based on a temperature profile. According to one embodiment, the temperature profile can be a profile of a targeted temperature change during an operating time. According to another embodiment, the temperature profile can be a profile of a current change provided during an operating time. The temperature of the vaporizer 14 can change due to the change in current.

[0052] For example, the vaporizer 14 may include, but is not limited to, a liquid reservoir, a liquid transfer means, and a heating element. For example, the liquid reservoir, the liquid transfer means, and the heating element may be included in the electronic device 1 as separate modules.

[0053] The liquid reservoir can store a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, or a liquid containing a non-tobacco substance. The liquid reservoir may be made detachable from the vaporizer 14, or may be made integral with the vaporizer 14.

[0054] For example, the liquid composition may include water, solvent, ethanol, plant extract, flavor, flavoring, or vitamin mixture. The flavor may include, but is not limited to, menthol, peppermint, spearmint oil, various fruit flavor ingredients, and the like. The flavoring may include ingredients that can provide a variety of flavors or tastes to the user. The vitamin mixture may include, but is not limited to, at least one of vitamin A, vitamin B, vitamin C, and vitamin E. In addition, the liquid composition may include an aerosol forming agent, such as glycerin and propylene glycol.

[0055] The liquid transfer means can transfer the liquid composition in the liquid reservoir to the heating element. For example, the liquid transfer means can be a wick such as, but not limited to, cotton fiber, ceramic fiber, glass fiber, porous ceramic, etc.

[0056] The heating element is an element for heating the liquid composition transferred by the liquid transfer means. For example, the heating element can be, but is not limited to, a metal hot wire, a metal hot plate, a ceramic heater, etc. The heating element may also be made of a conductive filament such as a nichrome wire, and may be arranged in a structure wound around the liquid transfer means. The heating element can be heated by current supply, and can transfer heat to the liquid composition in contact with the heating element to heat the liquid composition. As a result, an aerosol can be generated.

[0057] For example, the vaporizer 14 may be referred to as, but is not limited to, a cartomizer or an atomizer.

[0058] Meanwhile, the electronic device 1 may further include general-purpose components in addition to the detection unit 10, the battery 11, the control unit 12, the heater 13, and the vaporizer 14. For example, the electronic device 1 may include a display capable of outputting visual information and / or a motor for outputting tactile information.

[0059] According to an embodiment, the detection unit 10 may include one or more biosensors. For example, the biosensor may include one or more of a heart rate sensor, a blood pressure sensor, an electrocardiogram sensor, and a blood oxygen saturation sensor. The biosensor may include a sensor capable of measuring a biosignal of a user, and is not limited to the embodiment described. When a user holds the electronic device 1, the biosignal of the user may be measured.

[0060] According to an embodiment, the detection unit 10 may include a sensor capable of measuring the body composition of the user. For example, the body composition may include skeletal muscle mass, basal metabolic rate, body water content, and body fat content. When the user holds the electronic device 1, the body composition of the user may be measured.

[0061] According to an embodiment, the detection unit 10 may further include a puff detection sensor, a temperature detection sensor, and a cigarette insertion detection sensor. Also, the electronic device 1 may be manufactured in a structure that allows external air to flow in or internal gas to flow out even when the cigarette 2 is inserted.

[0062] 2 to 4, the electronic 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 electronic device 1. Alternatively, the heater 13 may be heated in a state where the cradle and the electronic device 1 are coupled together.

[0063] The cigarette 2 may be similar to a typical combustion-type cigarette. For example, the cigarette 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 the cigarette 2 may also include an aerosol-generating material. For example, an aerosol-generating material made in the form of granules or capsules may be inserted into the second portion.

[0064] The entire first part may be inserted into the electronic 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 electronic device 1, or the entire first part and a part of the second part may be inserted. A user can inhale aerosol while biting the second part in his / her mouth. In this case, the aerosol is generated by external air passing through the first part, and the generated aerosol is delivered to the user's mouth by passing through the second part.

[0065] As an example, the external air may flow in through at least one air passage formed in the electronic device 1. For example, the opening and closing of the air passage formed in the electronic device 1 and / or the size of the air passage may be adjusted by the user. This allows the user to adjust the amount of atomization, smoking sensation, etc. As another example, the external air may flow in to the inside of the cigarette 2 through at least one hole formed on the surface of the cigarette 2.

[0066] An example of a cigarette will now be described with reference to FIGS.

[0067] 5 and 6 are diagrams showing examples of cigarettes according to an embodiment.

[0068] 5, the cigarette 2 includes a tobacco rod 21 and a filter rod 22. A first portion of the cigarette 2 described above with reference to FIGS. 2 to 4 includes the tobacco rod 21, and a second portion of the cigarette 2 includes the filter rod 22.

[0069] 5, the filter rod 22 is shown as a single segment, but is not limited thereto. In other words, the filter rod 22 may be composed of multiple segments. For example, the filter rod 22 may include a segment for cooling the aerosol and a segment for filtering a predetermined component contained in the aerosol. In addition, the filter rod 22 may further include at least one segment for performing another function, if necessary.

[0070] The cigarette 2 may have a diameter in the range of 5 mm to 9 mm and a length of about 48 mm, but is not limited thereto. For example, the tobacco rod 21 may have a length of about 12 mm, the first segment of the filter rod 22 may have a length of about 10 mm, the second segment of the filter rod 22 may have a length of about 14 mm, and the third segment of the filter rod 22 may have a length of about 12 mm, but is not limited thereto.

[0071] The cigarette 2 may be wrapped by at least one wrapper 24. The wrapper 24 may have at least one hole through which external air can flow in or internal gas can flow out. As an example, the cigarette 2 may be wrapped by one wrapper 24. As another example, the cigarette 2 may be wrapped by two or more wrappers 24 in a superimposed manner. For example, the tobacco rod 21 may be wrapped by a first wrapper 24a, and the filter rod 22 may be wrapped by wrappers 24b, 24c, and 24d. Then, the entire cigarette 2 may be rewrapped by a single wrapper 24e. If the filter rod 22 is composed of a plurality of segments, each of the segments may be wrapped by the wrappers 24b, 24c, and 24d.

[0072] The first wrapper 24a and the second wrapper 24b may be made of a common filter wrapping paper. For example, the first wrapper 24a and the second wrapper 24b may be a porous wrapping paper or a non-porous wrapping paper. The first wrapper 24a and the second wrapper 24b may be made of a paper and / or an aluminum laminated paper wrapping material having oil resistance.

[0073] The third wrapper 24c may be made of hard wrapping paper. For example, the basis weight of the third wrapper 24c is 88 g / m 2 ~96g / m 2 and preferably 90 g / m 2 ~94g / m 2 The thickness of the third wrapper 24c may be within the range of 120 μm to 130 μm, and preferably 125 μm.

[0074] 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 and preferably 90 g / m 2 ~94g / m 2The thickness of the fourth wrapper 24d may be within the range of 120 μm to 130 μm, and preferably 125 μm.

[0075] The fifth wrapper 24e may be made of a sterile paper (MFW), which means a paper specially manufactured to have improved tensile strength, water resistance, smoothness, etc., compared to ordinary paper. For example, the basis weight of the fifth wrapper 24e is 57 g / m 2 ~63g / m 2 and preferably within the range of 60 g / m 2 The thickness of the fifth wrapper 24e may be in the range of 64 μm to 70 μm, and preferably 67 μm.

[0076] The fifth wrapper 24e may have a predetermined substance added thereto. Here, an example of the predetermined substance is silicon, but is not limited thereto. For example, silicon has properties such as heat resistance with little change due to temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency, and electrical insulation. However, any substance having the above-mentioned properties other than silicon may be applied (or coated) to the fifth wrapper 24e without any restrictions.

[0077] The fifth wrapper 24e can prevent the cigarette 2 from burning. For example, when the tobacco rod 21 is heated by the heater 13, the cigarette 2 may burn. Specifically, when the temperature rises above the ignition point of any of the substances contained in the tobacco rod 21, the cigarette 2 may burn. Even in such a case, the fifth wrapper 24e can prevent the cigarette 2 from burning because it contains a non-flammable substance.

[0078] Furthermore, the fifth wrapper 24e can prevent the holder from being contaminated by a substance generated from the cigarette 2. A liquid substance can be generated within the cigarette 2 by a user's puff. For example, a liquid substance (such as moisture) can be generated by cooling an aerosol generated from the cigarette 2 by external air. The fifth wrapper 24e wraps the cigarette 2, thereby preventing the liquid substance generated within the cigarette 2 from leaking to the outside of the cigarette 2.

[0079] The tobacco rod 21 includes an aerosol-generating material. For example, the aerosol-generating 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 being sprayed onto the tobacco rod 21.

[0080] The tobacco rod 21 may be made in various ways. For example, the tobacco rod 21 may be made in a sheet or in a strand. Also, the tobacco rod 21 may be made of shredded tobacco sheets. Furthermore, the tobacco rod 21 may be surrounded by a thermally conductive material. For example, the thermally conductive material may be a metal foil such as aluminum foil, but is not limited thereto. As an example, the thermally conductive material surrounding the tobacco rod 21 may evenly distribute the heat transferred to the tobacco rod 21 to improve the thermal conductivity applied to the tobacco rod, thereby improving the tobacco taste. Furthermore, the thermally conductive material surrounding the tobacco rod 21 may function as a susceptor heated by an induction heater. In this case, although not shown in the drawing, the tobacco rod 21 may further include an additional susceptor in addition to the thermally conductive material surrounding the outside.

[0081] The filter rod 22 may be a cellulose acetate 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 including a hollow inside. The filter rod 22 may also be a recessed rod. If the filter rod 22 is composed of a plurality of segments, at least one of the plurality of segments may be manufactured to have a different shape.

[0082] The first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tube-shaped structure having a hollow inside. The first segment can prevent the inner material of the tobacco rod 21 from being pushed backward when the heater 13 is inserted, and can also generate a cooling effect for the aerosol. The diameter of the hollow included in the first segment can be an appropriate diameter within the range of 2 mm to 4.5 mm, but is not limited thereto.

[0083] The length of the first segment may be within a range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first segment may be 10 mm, but is not limited thereto.

[0084] The hardness of the first segment can be adjusted by adjusting the content of the plasticizer during the manufacture of the first segment. Also, the first segment can be manufactured by inserting a structure such as a film or tube made of the same or different material inside (e.g., hollow).

[0085] 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 a suitable temperature.

[0086] 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 appropriately selected within the range of 7 mm to 20 mm. Preferably, the length of the second segment may be about 14 mm, but is not limited thereto.

[0087] The second segment may be made by weaving polymer fibers. In this case, the scented liquid may be applied to the fibers made of the polymer. Alternatively, the second segment may be made by weaving together a separate fiber to which the scented liquid is applied and a fiber made of the polymer. Alternatively, the second segment may be formed by a wound polymer sheet.

[0088] 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.

[0089] By forming the second segment from woven polymer fibers or wound polymer sheets, the second segment can include one or more longitudinally extending channels, where channel refers to a passageway through which a gas (e.g., air or aerosol) can pass.

[0090] For example, the second segment of wound polymer sheet can be formed from a material having a thickness between about 5 μm and about 300 μm, such as between about 10 μm and about 250 μm, and the total surface area of ​​the second segment can be less than about 300 mm 2 / mm and about 1000mm 2 / mm. Additionally, the aerosol cooling element may have a specific surface area of ​​about 10 mm 2 / mg and about 100mm 2 / mg of material.

[0091] Meanwhile, 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.

[0092] The third segment of the filter rod 22 may be a cellulose acetate filter. The length of the third segment may be within a range of 4 mm to 20 mm. For example, the length of the third segment may be about 12 mm, but is not limited thereto.

[0093] In the process of preparing the third segment, the third segment may be prepared so that a flavor is generated by spraying a flavoring liquid onto the third segment. Alternatively, a separate fiber coated with a flavoring liquid may be inserted into the third segment. The aerosol generated from the tobacco rod 21 is cooled as it passes through the second segment of the filter rod 22, and the cooled aerosol is delivered to the user 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 is produced.

[0094] The filter rod 22 may also include at least one capsule 23. Here, the capsule 23 may perform a function of generating flavor or a function of generating aerosol. For example, the capsule 23 may have a structure in which a liquid containing a flavoring agent is enveloped in a coating. The capsule 23 may have a spherical or cylindrical shape, but is not limited thereto.

[0095] 6, the cigarette 3 may further include a shear plug 33 compared to the cigarette 2. The shear plug 33 may be located on one side of the tobacco rod 31 facing the filter rod 32. The shear plug 33 may prevent the tobacco rod 31 from detaching to the outside, and may prevent aerosol liquefied from the tobacco rod 31 during smoking from flowing into the aerosol generating device (e.g., the electronic device 1 in FIGS. 2 to 4).

[0096] Filter rod 32 can include a first segment 32a and a second segment 32b, where first segment 32a can correspond to the first segment of filter rod 22 of FIG.

[0097] The diameter and overall length of the cigarette 3 can correspond to the diameter and overall length of the cigarette 2 of Figure 5. For example, but not limited to, the length of the shear plug 33 may be about 7 mm, the length of the tobacco rod 31 about 15 mm, the length of the first segment 32a about 12 mm, and the length of the second segment 32b about 14 mm.

[0099] Also, at least one perforation 36 may be formed in the fifth wrapper 35e. For example, but not limited to, the perforation 36 may be formed in the area surrounding the tobacco rod 31. The perforation 36 may play a role in transferring heat generated by the heater 13 shown in Figures 3 and 4 to the inside of the tobacco rod 31.

[0100] Further, the second segment 32b may include at least one capsule 34. Here, the capsule 34 may perform a function of generating a flavor or a function of generating an aerosol.

For example, the thickness of the fourth wrapper 35d may be in the range of 100 μm to 120 μm, and preferably 110 μm. The basis weight of the fourth wrapper 35d is 80 g / m 2 ~100g / m 2 and preferably 88 g / m 2 may be also possible.

[0106] The fifth wrapper 35e may be made of a sterile paper (MFW), which means a paper specially manufactured to have improved tensile strength, water resistance, smoothness, etc., compared to ordinary paper. For example, the basis weight of the fifth wrapper 35e is 57 g / m 2 ~63g / m 2 and preferably within the range of 60 g / m 2 The thickness of the fifth wrapper 35e may be in the range of 64 μm to 70 μm, and preferably 67 μm.

[0107] The fifth wrapper 35e may have a predetermined substance added thereto. Here, an example of the predetermined substance may be, but is not limited to, silicon. For example, silicon has properties such as heat resistance with little change due to temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency, and electrical insulation. However, any substance having the above-mentioned properties other than silicon may be applied (or coated) to the fifth wrapper 35e without any restrictions.

[0108] 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 the cellulose acetate tow.

The battery 84 may be a rechargeable battery or a disposable battery. For example, the battery 84 may be, but is not limited to, a lithium polymer (LiPoly) battery.

[0137] The heater 85 can heat the aerosol generating material by receiving power from the battery 84. Although not shown in Fig. 8, the electronic device 8 can further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of the battery 84 and supplies it to the heater 85. In addition, when the electronic device 8 generates the aerosol by an induction heating method, the electronic device 8 can further include a DC / AC converter that converts the DC power of the battery 84 into an AC power.

[0138] The control unit 81, the detection unit 82, the output unit 83, the user input unit 86, the memory 87, and the communication unit 91 can function by receiving power from the battery 84. Although not shown in Fig. 8, the device may further include a power conversion circuit, for example, an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the battery 84 and supplies it to each of the components.

[0140] In another embodiment, the heater 85 may be an induction heater, for example, the heater 85 may include a susceptor that generates heat via a magnetic field applied by a coil to heat the aerosol generating material.

[0141] In one embodiment, the heater 85 can include multiple heaters. For example, the heater 85 can include a first heater for heating the cigarette and a second heater for heating the liquid.

[0147] The control unit 81 can control the overall operation of the electronic device 8. In one embodiment, the control unit 81 can include at least one processor. The processor may be realized as an array of a plurality of logic gates, or may be realized as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. It will be understood by those skilled in the art to which this embodiment pertains that the processor may also be realized as other types of hardware.

[0148] The control unit 81 can control the temperature of the heater 85 by controlling the supply of power from the battery 84 to the heater 85. For example, the control unit 81 can control the power supply by controlling the switching of a switching element between the battery 84 and the heater 85. As another example, a heating direct circuit can control the power supply to the heater 85 according to a control command from the control unit 81.

[0149] The control unit 81 can analyze the results sensed by the detection unit 82 and then control the processing to be performed. For example, the control unit 81 can control the power supplied to the heater 85 so that the operation of the heater 85 starts or ends based on the results sensed by the detection unit 82. As another example, the control unit 81 can control the amount of power supplied to the heater 85 and the time for which the power is supplied so that the heater 85 is heated to a predetermined temperature or maintains an appropriate temperature based on the results sensed by the detection unit 82.

[0150] The control unit 81 may control the output unit 83 based on the result sensed by the detection unit 82.

[0151] In one embodiment, the control unit 81 may control the time and / or amount of power supplied to the heater 85 depending on the state of the aerosol-generating substrate sensed by the detection unit 82. For example, when the aerosol-generating substrate is in an overly humid state, the control unit 81 may control the time of power supply to the induction coil to increase the pre-heating time compared to when the aerosol-generating substrate is in a normal state.

[0152] FIG. 9 is a diagram illustrating a configuration of a user terminal according to an embodiment.

[0153] The user terminal 900 includes a communication unit 910, a processor 920, and a memory 930. For example, the user terminal 900 may be the user terminal 110 described above with reference to FIG.

[0154] The communication unit 910 is connected to the processor 920 and the memory 930 to transmit and receive data. The communication unit 910 may be connected to another external device to transmit and receive data. Hereinafter, the expression "transmitting and receiving 'A'" may indicate transmitting and receiving "information or data indicating A".

[0155] The communication unit 910 may be realized by a circuitry in the user terminal 900. For example, the communication unit 910 may include an internal bus and an external bus. As another example, the communication unit 910 may be an element that connects the user terminal 900 to an external device. The communication unit 910 may be an interface. The communication unit 910 may receive data from an external device and transmit the data to the processor 920 and the memory 930.

[0156] The processor 920 processes data received by the communication unit 910 and data stored in the memory 930. A "processor" may be a data processing device implemented in hardware having circuits with a physical structure for performing desired operations. For example, the desired 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).

[0157] The processor 920 executes computer readable code (eg, software) stored in a memory (eg, memory 930) and instructions triggered by the processor 920.

[0158] The memory 930 stores data received by the communication unit 910 and data processed by the processor 920. For example, the memory 930 may store a program (or application, software). The stored program may be a set of syntax that is coded to control an additional device (e.g., the electronic device 120 or the wearable device 130 in FIG. 1) and is executable by the processor 920.

[0159] According to one embodiment, memory 930 may include one or more of volatile memory, non-volatile memory and random access memory (RAM), flash memory, a hard disk drive, and an optical disk drive.

[0160] The memory 930 stores a set of instructions (eg, software) for operating the user terminal 900. The set of instructions for operating the user terminal 900 is executed by the processor 920.

[0161] The communication unit 910, the processor 920 and the memory 930 are described in more detail below with reference to FIG.

[0162] FIG. 10 is a flow chart of a method for generating an aerosol performed by an electronic device according to one embodiment.

[0163] The following operations 1010 to 1060 can be performed by an electronic device (eg, the electronic device 120 in FIG. 1, the electronic device 1 in FIG. 2 to FIG. 4, or the electronic device 700 in FIG. 7). For example, the electronic device may be an electronic cigarette device.

[0164] In operation 1010, the electronic device may receive biometric information of a user of the electronic device. For example, the biometric information may be at least one of the user's heart rate, skin temperature, skin dryness, and sweat secretion level. For example, the sweat secretion level may indicate the level of sweat secreted from the user's fingertips.

[0165] According to one embodiment, the electronic device can measure biometric information of the user using a sensor in a detector (eg, detector 10) of the electronic device.

[0166] According to another embodiment, the electronic device can receive biometric information of the user measured by an additional device (eg, wearable device 130 of FIG. 1) coupled to the electronic device.

[0167] Further, the electronic device may generate at least one of inhalation information and exhalation information of the user using the detection unit of the electronic device. For example, the electronic device may extract health data related to the user's heart rate, lung capacity, or air inhalation through the biometric information, inhalation information, and exhalation information, and may predict the user's current health condition due to physical or psychological factors (e.g., stress) based on the extracted health data.

[0168] Based on this, the electronic device can provide a service for relieving the user's stress in the short term and can provide a health care service to the user in the long term. For example, if the user's condition is predicted to be high stress (or tension) based on the biometric information, the inhalation information, and the exhalation information, the electronic device can induce the user to take a deep inhalation to relieve the user's high stress. The operation for inducing the user to take a deep inhalation will be described below.

[0169] In act 1020, the electronic device may determine a current state of the user based on the biometric information. For example, the electronic device may determine a current state of the user among a plurality of states based on the biometric information measured at a current time.

[0170] According to an embodiment, a plurality of states may be preset to correspond to the degree of stress of a user. For example, the plurality of states may include a normal state, a low stress state, and a high stress state. For example, it may be determined that the lower the temperature of the user's body extremities (e.g., fingers), the higher the degree of sweat secretion, and the more frequent the puffing cycle, the higher the stress.

[0171] According to one embodiment, a plurality of states can be preset based on demographic statistics regarding various element information to be measured. According to one example, a user can self-diagnose his / her own state and pre-set a plurality of states based on currently measured biometric information. For example, a user can self-diagnose his / her current state as normal and measure biometric information resulting from the normal state using an electronic device. The electronic device can personalize the individual state by setting the measured biometric information to a reference value resulting from the normal state.

[0172] In act 1030, the electronic device may determine whether the current state corresponds to a target state. For example, the electronic device may determine whether the current state corresponds to a high stress state.

[0173] If the current state corresponds to the target state, then operation 1050 below is performed; if the current state does not correspond to the target state, then operation 1040 below is performed.

[0174] In operation 1040, if the current state does not correspond to the target state, the electronic device can generate aerosol by heating an aerosol-generating substrate in the electronic device based on a base temperature profile. For example, the base temperature profile can be a temperature profile for providing aerosol to a user in a normal usage mode. Based on the temperature profile, the temperature of a heater (e.g., heater 13 in FIG. 2 or vaporizer 14 in FIG. 4) in the electronic device can be controlled.

[0175] In operation 1050, the electronic device may generate a target temperature profile by adjusting the base temperature profile based on the current state if the current state corresponds to the target state. The higher the stress state, the greater the amount of change in the base temperature profile. For example, when a user inhales mainstream smoke, the target temperature profile may be generated such that the amount of atomization generated by the aerosol-generating substrate is reduced. The user may take a deeper breath to restore the reduced amount of atomization. A deeper inhale may reduce the user's sense of tension or stress.

[0176] While the above-described embodiment describes a target temperature profile being generated by adjusting one basic temperature profile, in other embodiments, this may be replaced by determining a target basic temperature profile corresponding to the above-mentioned target state from among a plurality of basic temperature profiles pre-stored for a plurality of states.

[0177] According to one embodiment, the basic temperature profile or the basic temperature profiles may be pre-personalized temperature profiles by a user. For example, the user may personalize the temperature profile through a user terminal (e.g., an application on the user terminal) coupled to the electronic device.

[0178] In one embodiment, the electronic device can generate a target temperature profile such that a second amount of aerosol generated by the target temperature profile is reduced compared to a first amount of aerosol generated by the base temperature profile.

[0179] At operation 1060, the electronic device may generate aerosol by heating an aerosol-generating substrate within the electronic device based on the target temperature profile. A second amount of aerosol generated based on the target temperature profile may be reduced compared to the first amount of aerosol generated based on the base temperature profile. A user may take a deep breath to restore the reduced amount of aerosol (e.g., amount of atomization). A deep inhale may reduce the user's sense of tension or stress.

[0180] Operations 1010-1060 can be performed repeatedly.

[0181] Returning to operation 1010, the electronic device may receive a second biometric of the user.

[0182] In another operation 1020, the electronic device may determine a second current state of the user based on the second biometric information.

[0183] In a second operation 1030, the electronic device can determine whether the second current state corresponds to a pre-set target state, which can be the same as the target state set for the previous operation 1030 or can be a more stressful state.

[0184] In a second operation 1050, the electronic device may generate a second target temperature profile by adjusting the target temperature profile based on the second current state if the second current state corresponds to the target state. The third amount of aerosol generated based on the second target temperature profile may be further reduced compared to the second amount of aerosol generated based on the target temperature profile. The user may take a deeper breath to restore the reduced amount of aerosol (e.g., atomization amount). A deeper inhale may reduce the user's sense of tension or stress.

[0185] Again, in operation 1040, the electronic device can generate an aerosol by heating an aerosol-generating substrate within the electronic device based on the base temperature profile.

[0186] By repeatedly performing operations 1010-1060, if the user's current state is determined to be normal, the base temperature profile can be used to heat the aerosol-generating substrate.

[0187] FIG. 11 is a flow chart of a method for establishing a connection between an electronic device and an additional device according to an example embodiment.

[0188] According to one embodiment, before operation 1010 described above with reference to FIG. 10 is performed, the following operations 1110 and 1120 are further performed.

[0189] In operation 1110, the electronic device can propagate (or transmit) the beacon to an attached device (e.g., the wearable device 130 of FIG. 1) using short-range wireless communication. For example, the short-range wireless communication can be any of Bluetooth, BLE, NFC, and Wi-Fi, and is not limited to the described embodiment.

[0190] In operation 1120, the electronic device may connect to the additional device based on the beacon. For example, a channel may be formed between the electronic device and the additional device, and biometric information of the user generated by the additional device may be transmitted to the electronic device via the channel.

[0191] Although an embodiment in which the electronic device propagates the beacon and the additional device receives the beacon has been described through operations 1110 and 1120, an embodiment in which the additional device propagates the beacon and the electronic device receives the beacon may also be possible.

[0192] An embodiment in which aerosol is provided to a user based on a target temperature profile generated by an electronic device is described with reference to Figures 10 and 11, and an embodiment in which aerosol is provided to a user based on a target temperature profile generated by a user terminal is described below with reference to Figure 12.

[0193] FIG. 12 is a flowchart of a method for providing an aerosol to a user based on a temperature profile generated by a user terminal according to one embodiment.

[0194] The following operations 1210 to 1250 are performed by a user terminal (for example, the user terminal 110 in FIG. 1). For example, the operations 1210 to 1250 are performed by a program or application installed in the user terminal.

[0195] At operation 1210, the user terminal may receive a user's biometric information from an electronic device or an additional device coupled to the user terminal.

[0196] According to an embodiment, a detector (e.g., detector 10) of an electronic device (e.g., electronic device 120 of FIG. 1, electronic device 1 of FIGS. 2-4, electronic device 700 of FIG. 7) can measure biometric information of a user and transmit the biometric information to a user terminal. Furthermore, the electronic device can further measure inhalation information and exhalation information and transmit the inhalation information and exhalation information to the user terminal.

[0197] According to one embodiment, a detector of an additional device (eg, the wearable device 130 of FIG. 1) can measure biometric information of a user and transmit the biometric information to a user terminal.

[0198] In operation 1220, the user terminal may determine a current state of the user based on the biometric information. For example, the user terminal may determine a current state of the user based on at least one of the biometric information, the inhalation information, and the exhalation information. For the method of determining the current state of the user, the description of operation 1020 described above with reference to FIG. 10 may be similarly applied.

[0199] In operation 1230, the user terminal may determine whether the current state corresponds to a target state. For example, the user terminal may determine whether the current state corresponds to a high stress state.

[0200] If the current state corresponds to the target state, the following operation 1240 is performed, and if the current state does not correspond to the target state, no additional operations may be performed. In the absence of a special command (or instruction) from the user terminal, the electronic device may heat the aerosol-generating substrate using the basic temperature profile, and the heated aerosol-generating substrate may provide an aerosol to the user.

[0201] In operation 1240, the user terminal can generate a target temperature profile by adjusting the basic temperature profile based on the current state. For the method of generating the target temperature profile, the description of operation 1050 described above with reference to FIG. 10 can be similarly applied.

[0202] In operation 1250, the user terminal may transmit the target temperature profile to the electronic device. For example, the user terminal may transmit the target temperature profile to the electronic device over a short-range wireless communication channel with the electronic device.

[0203] According to one embodiment, the electronic device may generate aerosol by heating an aerosol-generating substrate within the electronic device based on a target temperature profile received from a user terminal. A second amount of aerosol generated based on the target temperature profile may be reduced compared to a first amount of aerosol generated based on the base temperature profile. A user may take a deep breath to restore the reduced amount of aerosol (e.g., atomization amount). A deep inhale may reduce the user's sense of tension or stress.

[0204] The method according to the embodiment may be realized in the form of program instructions executed by various computer means and recorded on a computer readable medium. The computer readable medium may include, alone or in combination, program instructions, data files, data structures, and the like. The program instructions recorded on the medium may be specially designed and constructed for the embodiment, or may be known and available to those skilled in the art of computer software. Examples of computer readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes, 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 Read Only Memory (ROM), RAM, and flash memory. Examples of program instructions include not only machine language code, such as produced by a compiler, but also high-level language code that can be executed by a computer using an interpreter, or the like. The above hardware devices may be configured to operate as one or more software modules to perform the operations of the embodiment, and vice versa.

[0205] The software may include computer programs, codes, instructions, or a combination of one or more of these, and may configure or instruct a processing device to operate in a desired manner, either independently or in combination. The software and / or data may be permanently or temporarily embodied in some 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 may also be distributed over computer systems coupled to a network, and stored or performed in a distributed manner. The software and data may be stored in one or more computer-readable recording media.

[0206] As described above, although the embodiments have been described with reference to limited drawings, those having ordinary skill in the art may apply various technical modifications and variations based on the above. For example, the described techniques may be performed in a different order from that described, and / or the components of the described systems, structures, devices, circuits, etc. may be combined or combined in a different manner from that described, or may be replaced or substituted by other components or equivalents, and still achieve suitable results.

[0207] Therefore, other embodiments, other examples, and equivalents to the claims also fall within the scope of the claims set forth below.
