[0011] The terms used in the embodiments are generally used in the present invention, taking into consideration their functions in the present invention. However, these terms may change depending on the intentions of those skilled in the art, legal precedents, the emergence of new technologies, etc. In addition, in certain cases, the applicant may arbitrarily select terms, and in such cases, their meanings will be described in detail in the description of the invention. Therefore, the terms used in the present invention should be defined based on the meanings of the terms and the overall content of the present invention, rather than simply by their names.

[0012] Throughout the specification, when a part "includes" a certain element, this does not mean that it excludes other elements and may further include other elements, unless otherwise specified. Furthermore, terms such as "module" and "unit" used in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware or software, or a combination of hardware and software.

[0013] As used herein, when a phrase such as "at least one of," precedes an element in an arrangement, it modifies the entire element and not each individual element in the arrangement. For example, the phrase "at least one of a, b, and c" should be interpreted as including a, b, and c, or a and b, a and c, b and c, or a, b, and c.

[0014] In one embodiment, the aerosol generating device is a device that generates an aerosol by electrically heating a cigarette contained in an internal space.

[0015] The aerosol generating device comprises a heater, in one embodiment the heater is an electrically resistive heater, for example the heater comprises an electrically conductive track, and when an electric current is passed through the electrically conductive track the heater is heated.

[0016] The heater may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and may heat the inside or outside of the cigarette depending on the shape of the heating element.

[0017] Cigarettes include tobacco rods and filter rods. The tobacco rods may be made of sheets, strands, or shredded tobacco from a tobacco sheet. The tobacco rods may also 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.

[0018] The filter rod may also be a cellulose acetate filter. The filter rod may be composed of at least one or more segments. For example, the filter rod may have a first segment that cools the aerosol and a second segment that filters out certain components contained in the aerosol.

[0019] In another embodiment, the aerosol generating device is a device that generates the aerosol using a cartridge containing an aerosol generating material.

[0020] The aerosol generating device includes a cartridge containing an aerosol-generating material and a body supporting the cartridge. The cartridge is detachably connected to the body, but is not limited thereto. The cartridge may be formed integrally with the body, incorporated therein, or fixed so as not to be detachable by a user. The cartridge is attached to the body with the aerosol-generating material contained therein. However, is not limited thereto, and the aerosol-generating material may be injected into the cartridge while the cartridge is connected to the body.

[0021] The cartridge contains an aerosol-forming material in any one of various states, such as a liquid, solid, gas, or gel. The aerosol-forming material includes a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance that includes a volatile tobacco flavor component, or a liquid containing a non-tobacco substance.

[0022] The cartridge is activated by an electrical signal or a wireless signal transmitted from the main body to convert the phase of the aerosol-generating material inside the cartridge into a gas phase, thereby generating an aerosol. The aerosol refers to a gas mixture of vaporized particles generated from the aerosol-generating material and air.

[0023] In yet another embodiment, the aerosol generating device heats a liquid composition to generate an aerosol, and the generated aerosol is delivered to the user through the cigarette, i.e., the aerosol generated from the liquid composition travels along an airflow passage of the aerosol generating device, and the airflow passage is configured to deliver the aerosol through the cigarette to the user.

[0024] In yet another embodiment, the aerosol generating device may be a device that generates an aerosol from an aerosol generating material using an ultrasonic vibration method, which refers to a method of generating an aerosol by atomizing an aerosol generating material using ultrasonic vibrations generated by a vibrator.

[0025] The aerosol generating device includes a vibrator that generates short-period vibrations to atomize the aerosol generating material. The vibrations generated by the vibrator are ultrasonic vibrations, and the frequency band of the ultrasonic vibrations is, but is not limited to, about 100 kHz to about 3.5 MHz.

[0026] The aerosol generating device further includes a wick that absorbs the aerosol-generating substance, for example, the wick is positioned to surround or contact at least a region of the vibrator.

[0027] When a voltage (e.g., an AC voltage) is applied to the vibrator, heat and / or ultrasonic vibrations are generated from the vibrator, and the heat and / or ultrasonic vibrations generated from the vibrator are transferred to the aerosol-forming substance absorbed in the wick. The aerosol-forming substance absorbed in the wick is converted into a gas phase by the heat and / or ultrasonic vibrations transferred from the vibrator, resulting in the generation of an aerosol.

[0028] For example, the heat generated from the vibrator reduces the viscosity of the aerosol-generating substance absorbed in the core, and the ultrasonic vibrations generated from the vibrator break the reduced viscosity aerosol-generating substance into fine particles, thereby generating an aerosol, but this is not limiting.

[0029] In yet another embodiment, the aerosol generating device is a device that generates an aerosol by heating an aerosol product contained in the aerosol generating device using an induction heating method.

[0030] The aerosol generating device includes a susceptor and a coil. In one embodiment, the coil applies a magnetic field to the susceptor. When power is supplied from the aerosol generating device to the coil, a magnetic field is formed inside the coil. In one embodiment, the susceptor is a magnetic material that generates heat when an external magnetic field is applied. When the susceptor is located inside the coil and a magnetic field is applied, the susceptor generates heat, thereby heating the aerosol product. Alternatively, the susceptor may be located inside the aerosol product.

[0031] In yet another embodiment, the aerosol generating device further comprises a cradle.

[0032] The aerosol generating device may be combined with a separate cradle to form a system. For example, the cradle may charge a battery of the aerosol generating device. Alternatively, the heater may heat the aerosol generating device when the cradle and the aerosol generating device are combined.

[0033] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. The present invention may be embodied in a form that can be implemented in the aerosol generating device of the various embodiments described above, or may be embodied in various different forms, but is not limited to the embodiments described herein.

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0035] FIG. 1 is a perspective view of an aerosol generating device according to one embodiment.

[0036] Referring to Figure 1, an aerosol generating device 100 according to one embodiment includes a housing 110 that forms the overall appearance of the aerosol generating device 100, and a storage space 110i that is arranged in at least one region of the housing 110 and that is used to store an aerosol product.

[0037] The aerosol generating device 100 stores an aerosol product (not shown) and generates an aerosol by heating the stored aerosol product. The aerosol generated by the aerosol generating device 100 is supplied to a user by the user's inhalation (or puffing), and the user inhales through this process.

[0038] The housing 110 includes an accommodation space (or "interior space") in which the components of the aerosol generation device 100 are disposed. The accommodation space of the housing 110 is where the components of the aerosol generation device 100 are disposed.

[0039] For example, a heater for heating at least a region of the aerosol product contained in the container 110i, a battery for supplying power to the heater, and a processor are disposed in the container space of the housing 110. In this case, the heater may include, but is not limited to, a coil for generating an alternating magnetic field and a susceptor that generates heat due to the alternating magnetic field generated by the coil.

[0040] Furthermore, the above-mentioned components are merely examples of components of the aerosol generating device 100 that can be placed in the storage space of the housing 110, and the components of the aerosol generating device 100 that can be placed in the storage space of the housing 110 are not limited to these.

[0041] The aerosol product is heated by the heating element, and an aerosol is generated in the storage space of the housing 110. The generated aerosol is discharged to the outside of the aerosol generation device 100 through the aerosol product stored in the storage section 100i or the empty space between the aerosol product and the storage section 100i, and the user inhales the discharged aerosol.

[0042] Although the drawings only show an embodiment in which the cross section of the housing 110 is generally semicircular, the shape of the housing 110 is not limited thereto. Depending on the embodiment (not shown), the housing 110 may be generally cylindrical or polygonal (e.g., triangular or quadrangular) in shape.

[0043] The aerosol generating device 100 according to one embodiment further includes a display 120 arranged so as to be exposed to at least one region on the outside of the housing 110. For example, the display 120 is arranged so as to be exposed to at least one region through a cover glass on the outside of the housing 110.

[0044] The display 120 includes a display panel and a touch panel that receives touch input. For example, the display panel includes scan lines, data lines, and light-emitting elements (e.g., organic light-emitting diodes (OLEDs) and light-emitting diodes (LEDs)) that emit light based on signals supplied from the scan lines and data lines. The touch panel detects changes in electrical characteristics (e.g., capacitance, radio waves, etc.) due to a user's touch input, and position information of the detected change is transmitted to a processor.

[0045] The aerosol generating device 100 provides various visual information to the user through the display 120. For example, the aerosol generating device 100 displays preheating and heating information for the aerosol product, remaining battery power, time and date information, usage mode information, weather information, Bluetooth connection information, etc. through the display 120. The information displayed through the display 120 is merely exemplary and is not limited to the above-described embodiment.

[0046] FIG. 2 is a diagram showing a coil of an aerosol generating device according to an embodiment, and a cutaway enlarged view of a portion of the coil.

[0047] Referring to FIG. 2, an aerosol generating device according to one embodiment (for example, the aerosol generating device 100 of FIG. 1) includes a container 200 and a coil 220.

[0048] The container 200 may include a container space for containing the aerosol product, and at least a region of the aerosol product is contained within the container space.

[0049] The coil 220 is disposed to surround at least a region of the outer periphery of the container 200, and can generate an alternating magnetic field when power is supplied thereto. A susceptor (not shown) is disposed inside the container space of the container 200 or on the aerosol product contained in the container space, and can generate heat by the alternating magnetic field generated by the coil 220 to heat the aerosol product contained in the container space of the container 200. The smaller the resistance value of the coil 220, the greater the amount of heat generated by the susceptor.

[0050] According to one embodiment, the coil 220 is embodied in a solenoid shape by winding the receiving part 200 along a first direction in which the receiving part 200 extends. When a current is supplied to the solenoid coil 220, the coil 220 generates an alternating magnetic field in the internal space of the coil 220. The generated magnetic field passes through the receiving part 200, and if an aerosol product (not shown) is stored in the receiving part 200, it passes through the aerosol product.

[0051] According to one embodiment, the wire 223 forming the coil 220 includes, from the inside out, at least one of a conductor 231, an insulator 232, and a bonding material 233. The conductor 231 includes a Litz wire made by twisting strands of wire, and the bonding material 233 forms the coil 220 into a flat coil having a desired shape.

[0052] A Litz coil is a coil made by weaving about 10 to 100 strands of Litz wire, a thin conductor with a diameter of about 0.1 mm, which increases the surface area physically and improves frequency characteristics electrically. This reduces the skin effect, lowering the effective resistance of the coil and improving the heating efficiency of the coil when subjected to high-frequency AC current.

[0053] The flat coil has a larger cross-sectional area than the Litz coil, which reduces the effective resistance. Also, since the flat coil is a single coil, the spacing between adjacent conductors can be narrowed.

[0054] As a result, the coil 220, in which the Litz coil is formed into a flat coil, reduces the effective resistance, improving the heating efficiency of the coil 220, while also enabling the aerosol generating device to be made smaller by efficiently utilizing space.

[0055] The insulator 232 is formed outside the conductor 231 and coaxially with the conductor 231. If the conducting wire 233 forming the coil 220 includes the conductor 231 and the insulator 232 but does not include the bonding material 233, production costs can be reduced. However, the bonding material 233 can fix the coil 220 in a desired shape.

[0056] When the conductor 231 is wound into a desired shape, heat treatment is performed on the bonding body 233, which causes bonding between the wires and fixes the coil 220 into the desired shape. The heat treatment temperature is equal to or lower than the heat resistance temperature of the conductor 231 and the insulator 232, and equal to or higher than the heat resistance temperature of the bonding body 233.

[0057] When the bonding body 233 is heat-treated to fuse the wires, the bonding body 233 melts, thereby minimizing the gap between the conductive wires 223 forming the coil 220. The narrow gap between the conductive wires 223 allows for efficient use of the storage space of the aerosol generating device.

[0058] The bonding body 233 includes at least one of polyamide, polyvinyl butyral, and polyimide. In one example, the bonding body 233 includes polyamide, which has excellent adhesive properties and a high melting point due to hydrogen bonding. In another example, the bonding body 233 includes polyvinyl butyral, which has excellent adhesive properties, can be manufactured as a thermosetting material, and is suitable for fixing the coil 220 in a desired shape. In yet another example, the bonding body 233 includes polyimide, which has excellent heat resistance, can reduce the possibility of phase change of the bonding body 233, has little change in properties over a wide temperature range, and has excellent electrical properties.

[0059] The inductance value of the coil 220 is proportional to the number of turns of the wire per unit length, as shown in Equation 1.

number

[0060] In Equation 1, μ_0 represents the magnetic permeability in a vacuum, n represents the number of wires wound per unit length, l represents the length of the coil 220, and A represents the cross-sectional area of ​​the coil 220.

[0061] The electromotive force generated by the coil 220 when an AC current is supplied is proportional to the inductance value of the coil 220 as shown in Equation 2.

number

[0062] In Equation 2, V is the electromotive force, L is the inductance of the coil 220, and di / dt is the time rate of change of the supplied AC current. Therefore, the larger the number of wires wound per unit length n, the length l of the coil 220, and the cross-sectional area A of the coil 220 (specifically, the cross-sectional area perpendicular to the longitudinal direction of the coil 220), the higher the inductance value, and therefore the higher the electrical efficiency of the coil 220.

[0063] According to one embodiment, the coil 220 formed into a flat coil includes a circular coil cross section 230. However, without being limited thereto, the coil cross section 230 of the coil 22 formed into a flat coil may be triangular or rectangular.

[0064] The number of turns per unit length of the coil varies depending on the shape of the coil cross section 230 included in the coil 220 formed into a flat coil, which in turn varies the inductance value of the coil 220. The inductance value of the coil 220 can be controlled by varying the shape, size, or number of the coil cross section 230 included in the coil 220 formed into a flat coil.

[0065] The solenoid coil 220 is made up of a single conductor 223 and has a pair of power supply lines 221 and 222 at both ends.

[0066] 3A is a diagram illustrating an enlarged cutaway view of a coil of an aerosol generating device according to another embodiment, and FIG. 3B is a diagram illustrating a coil of an aerosol generating device according to yet another embodiment.

[0067] The spiral coil 320 shown in FIGS. 3A and 3B is a coil that is different from the solenoid coil 220 shown in FIG. 2 only in shape and arrangement, and therefore, overlapping descriptions will be omitted below.

[0068] 3A and 3B, the coil 320 is disposed to surround at least a region of the outer circumferential surface of the receiving portion 300. According to one embodiment, the coil 320 is embodied in a spiral shape wound around a central axis extending in a second direction intersecting the first direction in which the receiving portion 300 extends.

[0069] Specifically, when current is supplied to the coil 320 shown in Figures 3A and 3B, the coil 320 generates an alternating magnetic field inside the receiving space of the receiving part 300, and the conductive wire 323 forming the coil 320 shown in Figures 3A and 3B includes, from the inside, at least one of a conductor 331, an insulator 332, and a bonding material 333, and if the coil 320 shown in Figures 3A and 3B is formed into a flat coil, it includes a circular coil cross section 330.

[0070] According to one embodiment, the coil 320 is wound in a shape with a gradually increasing diameter, with its central axis located at a point on the outer circumferential surface of the receiving portion 300. The coil 320 forms a curved surface, and the curved surface is disposed so as to surround a region of the outer circumferential surface of the receiving portion 300.

[0071] The coil 320 is wound around a plurality of central axes spaced apart from each other at different points on the outer periphery of the receiving part 300. For example, the coil 320 shown in Fig. 3A is implemented as two spiral coils 320 wound around two central axes spaced apart from each other at two different points on the outer periphery of the receiving part 300.

[0072] The coil 320 may be realized as a spiral coil 320 that is wound around a plurality of central axes spaced apart from one another in a circular shape, but the number, size, and shape of the spiral coil 320 are not limited to those described above and may be modified as needed.

[0073] The magnetic field generated by supplying current to the coil 320 follows Ampere's law. The direction of the magnetic field generated by the arrangement of the coil 320 shown in Figures 3A and 3B is a second direction transverse to the extension direction of the receiving part 300. On the other hand, the direction of the magnetic field generated by the arrangement of the coil 220 shown in Figure 2 is a first direction, which is the extension direction of the receiving part 300.

[0074] Specifically, the density of the magnetic field passing through the container 300 and the aerosol product (not shown) contained therein is greater when generated by the spiral coil 320 shown in Figures 3A and 3B than when generated by the solenoid coil 220 shown in Figure 2. Therefore, the heating efficiency of the spiral coil 320 shown in Figures 3A and 3B is superior to that of the solenoid coil 220 shown in Figure 2.

[0075] 3A and 3B, the spiral coils 320 may have the same size and shape and are connected via a coil connection part 324. The coil 320 is made up of a single conductor 323 and has a pair of power supply lines 321 and 322 at both ends.

[0076] 3B, the coil 320 is realized as two spiral coils 320 wound around four central axes spaced apart from each other at four points on the outer periphery of the receiving part 300. The four spiral coils 320 are arranged symmetrically in pairs around the receiving part 300, and according to Ampere's law, the arrangement of the spiral coils 320 minimizes the proportion of magnetic fields that cancel each other out.

[0077] 3B, the coil supporters 340 are disposed to protrude outward from at least one region of the outer circumferential surface of the receiving part 300, but are not limited thereto. Also, the coils 320 are embodied as spiral coils 320 that are wound in a circular shape around the respective coil supporters 340 that support the respective coils 320. However, even if the coil supporters 340 do not support the coils 320, they may function to indicate the position of the central axis around which the coils 320 are wound.

[0078] FIG. 4 is a schematic diagram of an aerosol product according to one embodiment.

[0079] Referring to FIG. 4, the aerosol production product 400 includes a first medium portion 410, a second medium portion 420, a cooling portion 430, and a filter portion 440.

[0080] In one embodiment of the aerosol product 400, the first medium portion 410 contains an atomization-generating substance, and the second medium portion 420 contains nicotine.

[0081] For example, the first medium portion 410 may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. Also, the first medium portion 410 may not include nicotine.

[0082] For example, the second medium portion 420 may be made of shredded tobacco, which is made by shredding a tobacco sheet. In another example, the second medium portion 420 may contain a mixture of shredded tobacco and flat tobacco in a ratio of about 4:1, but is not limited to the aforementioned ratio.

[0083] The aerosol product (not shown) according to another embodiment is an aerosol product obtained by changing only the second medium portion (not shown) of the aerosol product 400 according to the first embodiment, and therefore, a duplicated description will be omitted below.

[0084] For example, the second medium may be a crimped sheet impregnated with a nicotine solution. The crimped sheet may be, but is not limited to, a paper sheet that does not produce an unpleasant odor even when heated to a high temperature.

[0085] An aerosol product (not shown) according to yet another embodiment is an aerosol product obtained by changing only the second medium portion (not shown) of the aerosol product 400 according to the above embodiment, and therefore, a duplicated description will be omitted below.

[0086] For example, the second medium may include a plurality of tobacco granules. Tobacco granules refer to spherical particles containing tobacco material. The plurality of tobacco granules are embedded among filter material. The second medium may include, but is not limited to, a paper sheet, in which the plurality of tobacco granules are uniformly dispersed within the wound paper sheet.

[0087] The cooling unit 430 can provide aerosol cooled to an appropriate temperature to a user by lowering the temperature of the generated aerosol. For example, the cooling unit 430 can be a hollow tubular structure containing cellulose acetate. However, the cooling unit 430 is not limited to the above example, and can be used without limitation as long as it has the effect of cooling the aerosol.

[0088] The filter unit 440 includes at least one capsule. For example, the capsule may contain a liquid fragrance, and the flavor may be generated by the exposed fragrance when the capsule is crushed, but this is not limiting.

[0089] The aerosol product article 400 further includes a wrapper 450 that surrounds the outer periphery of the aerosol product article 400. The wrapper 450 may include separate wrappers (not shown) that surround the outer periphery of each segment, or an outer wrapper (not shown) that surrounds the entire outer periphery of the aerosol product article 400.

[0090] The aerosol production article 400 further includes a susceptor (not shown) therein.

[0091] According to one embodiment, the susceptor is included in the second medium portion 420. For example, the susceptor may be formed in the form of a sheet or strand, or may be dispersed within the second medium portion 420 in the form of particulates.

[0092] According to another embodiment, the susceptor is included inside a wrapper 450 that surrounds at least a portion of the outer periphery of the second medium portion 420. The susceptor includes a thin metal film. When the susceptor includes a thinly applied metal film, the heat generation efficiency can be maximized relative to the mass of the susceptor, improving heating efficiency, and the heat generation efficiency can be maximized relative to the volume of the susceptor, allowing for efficient use of the internal space of the aerosol generator (not shown). The metal film may be, but is not limited to, an aluminum film.

[0094] An aerosol generating device according to one embodiment (e.g., the aerosol generating device 100 of FIG. 1) includes a container 500 and coils 520, 540, and 560. At least one of the components of the aerosol generating device is the same as or similar to at least one of the components of the aerosol generating devices shown in FIGS. 2, 3A, and 3, and therefore, overlapping descriptions will be omitted below.

[0095] Referring to FIG. 5A, in one example, the coil 520 may include a solenoid-type coil in which one or more Litz coils are formed into a flat coil, and the coil 520 is arranged to surround at least a region of the outer circumferential surface of the receiving portion 500.

[0097] Referring to FIG. 5B, in another example, the coil 540 includes a spiral coil in which one or more Litz coils are formed into a flat coil, and the coil 540 is arranged to wrap around at least a region of the outer circumferential surface of the receiving portion 500.

[0098] According to another embodiment, a Litz coil is formed into a flat coil, and a spiral coil 541 having a first resistance value is arranged, and a Litz coil is formed into a flat coil, and a spiral coil 542 having a second resistance value different from the first resistance value is arranged spaced apart from the coil 541 along a first direction in which the accommodating portion 500 extends.

[0099] Referring to FIG. 5C, in yet another example, the coil 560 includes a solenoid coil in which one or more Litz coils are formed into a flat coil, and a spiral coil in which one or more Litz coils are formed into a flat coil, and the coil 560 is arranged to wrap around at least a region of the outer circumferential surface of the receiving portion 500.

[0101] An aerosol product according to one embodiment (e.g., aerosol product 400 in FIG. 4) includes a first medium portion (e.g., first medium portion 410 in FIG. 4) containing a substance that generates atomization, and a second medium portion (e.g., second medium portion 420 in FIG. 4) containing nicotine. By heating each segment of the aerosol product differently, the quality of the aerosol provided to the user varies. In the present invention, "aerosol quality" refers to the amount of aerosol generated and / or the amount of flavor perceived when the user inhales the aerosol, and these terms are used interchangeably below.

[0102] For example, if the first medium portion 410 is heated relatively more than the second medium portion 420, the amount of aerosol generated and provided to the user increases, and if the second medium portion 420 is heated relatively more than the first medium portion 410, the amount of flavor per unit volume of aerosol provided to the user increases.

[0103] An aerosol generating system according to one embodiment includes an aerosol product and an aerosol generating device.

[0104] The aerosol production product is the same as or similar to the aerosol production product shown in Figure 4, and the overlapping description will be omitted below. The aerosol generating device is the same as or similar to at least one of the coils 520, 540, and 560 shown in Figures 5A to 5C, and the overlapping description will be omitted below.

[0105] The aerosol generating device may further include a battery, a processor that controls power supplied from the battery to the coil, a susceptor that generates heat by a magnetic field generated by the coil when power is supplied to the coil, a sensor that detects the type of aerosol product, and a memory that stores a temperature profile that allows the processor to supply power according to the type of aerosol product, etc. This is merely an example and is not limited to this.

[0106] A coil in which a Litz coil is formed into a flat coil (for example, coils 520, 540, and 560 in FIG. 5) reduces the effective resistance and improves the heating efficiency of the coil, while also enabling the aerosol generation device to be made smaller by efficiently utilizing space.

[0107] The number of turns per unit length of the coil varies depending on the shape of the coil cross section (not shown) of the Litz coil formed into a flat coil, and the inductance value of the coil also varies. By varying the shape, size, or number of the coil cross sections of the Litz coil formed into a flat coil, the inductance value of the coil (e.g., coils 521, 522, 541, 542, 561, and 562 in FIG. 5) can be controlled.

[0108] The density of the magnetic field passing through the container 500 and the aerosol product (not shown) contained therein can be greater when generated by a solenoid coil (e.g., coils 521, 522, 561 in Figure 5A or 5C) than when generated by a helical coil (e.g., coils 541, 542, 562 in Figure 5B or 5C), so the desired magnitude of the magnetic field density can be controlled.

[0109] In one embodiment, an aerosol generating device simultaneously improves power efficiency and reduces the size of the device by arranging a coil in which a Litz coil is formed into a flat coil, and expands the range in which the quality of the aerosol can be controlled by arranging two solenoid and / or spiral coils formed to have different resistance values ​​so that they surround the outer peripheral surface of the first medium portion or the second medium portion, respectively.

[0110] FIG. 6 is a diagrammatic illustration of the arrangement of the coil cross section of an aerosol production article according to one embodiment.

[0111] An aerosol generating device according to one embodiment (e.g., the aerosol generating device 100 in FIG. 1) includes a container (e.g., the container 100i in FIG. 1) and coils 620, 640, 660, and 680. At least one of the components of the aerosol generating device is the same as or similar to at least one of the components of the aerosol generating devices shown in FIGS. 2, 3A and 3B, and 5A to 5C, and therefore, overlapping descriptions will be omitted below.

[0112] 6, according to one embodiment, first coil 624 includes coils 620 and 640 formed by flattening one or more Litz coils, and first coil 624 is disposed to surround at least a region of the outer periphery of receiving portion 600. Coil 620 of first coil 624 and coil 640 of first coil 624 are electrically connected to each other.

[0113] The second coil 668 includes coils 660 and 680 formed by forming one or more Litz coils into flat coils, and the second coil 668 is disposed to surround at least a region of the outer circumferential surface of the receiving portion 600. The coil 660 of the second coil 668 and the coil 680 of the second coil 668 are electrically connected to each other.

[0114] A first coil 624 having a first resistance value is arranged in one region of the outer surface of the accommodating portion 600 so as to heat a second medium portion (e.g., second medium portion 420 in FIG. 4), and a second coil 668 having a second resistance value different from the first resistance value is arranged in another region of the outer surface of the accommodating portion 600 so as to heat a first medium portion (e.g., first medium portion 410 in FIG. 4).

[0115] According to one embodiment, the first coil 624 includes a coil 620 having a coil cross section 621 and a coil 640 having a coil cross section 641, and the second coil 668 includes a coil 660 having a coil cross section 661 and a coil 680 having a coil cross section 681.

[0116] For example, coil 620 includes three larger circular coil sections 621, coil 640 includes four smaller circular coil sections 641, coil 660 includes five triangular coil sections 661, and coil 680 includes three rectangular coil sections 681. Each of coils 620, 640, 660, and 680 is a solenoidal coil and / or a helical coil.

[0117] The foregoing is merely an example and may be modified as understood by those skilled in the art to suitably control aerosol quality while simultaneously achieving power efficiency and compactness of the device.

[0118] 7 is a block diagram that schematically illustrates components of an aerosol generating device according to one embodiment. The aerosol generating device 700 shown in FIG. 7 is an embodiment of the aerosol generating device 100 shown in FIG.

[0119] 7, an aerosol generating device 700 according to one embodiment includes a processor 710, a battery 720, a coil 730, a heating element 740, a sensor 750, and a memory 760. However, the above-mentioned components are merely an example of the aerosol generating device 700, and the components of the aerosol generating device 700 are not limited to those shown in FIG.

[0120] The processor 710 is electrically or operatively coupled to the battery 720, the coil 730, the heating element 740, the sensor 750, and / or the memory 760 to control the overall operation of the aerosol generating device 700. The coil 730 generates an alternating magnetic field by receiving power from the battery 720 under the control of the processor 710, and the generated magnetic field causes the heating element 740 to electrically generate heat to heat the aerosol product (not shown).

[0121] The sensor 750 is an inductance sensor that detects the type of aerosol product contained in the aerosol generation device 700. The processor 710 senses, via the sensor 750, changes in the electrical characteristics inside the container (e.g., container 100i in FIG. 1 ) of the aerosol generation device 700, which vary depending on the type of aerosol product contained therein, and detects the type of the aerosol product contained based on the sensing results. For example, the processor 710 detects the type of aerosol product determined by the combination of a first medium portion (e.g., first medium portion 410 in FIG. 4 ) and a second medium portion (e.g., second medium portion 420 in FIG. 4 ) contained in the aerosol product.

[0122] The processor 710 detects the type of aerosol product contained in the aerosol generating device 700 via the sensor 750, and outputs a user interface (UI) indicating the type of aerosol product via a display (e.g., display 120 of Figure 1) based on the type of aerosol product contained.

[0123] Based on the type of aerosol product detected, processor 710 controls the power provided by battery 720 to coil 730 to cause heating element 740 to generate heat and adjust the temperature profile for heating the aerosol product. Memory 760 stores data related to the temperature profiles corresponding to the type of aerosol product contained.

[0124] Referring to Figures 5A to 5C described above, by arranging a coil in which a Litz coil is formed into a flat coil, power efficiency and the size of the device are simultaneously improved, and by arranging two solenoid-type and / or spiral-type coils formed to have different resistance values ​​so as to surround the outer circumferential surface of the first medium portion or the second medium portion, respectively, the range in which the aerosol quality can be controlled is expanded.

[0125] This allows the aerosol generating device 700 to maintain the aerosol quality of various types of aerosol products at an optimal and uniform state simply by having the processor 710 control the power supplied from the battery 720 to the coil 730 based on a temperature profile determined by the type of aerosol product.

[0126] 8 is a flowchart showing an operation of controlling the power supply to the coil based on the type of aerosol product contained in the aerosol generating device according to one embodiment. In the following, when describing the operation of controlling the power supply to the aerosol generating device, reference will be made to the components of the aerosol generating device shown in FIGS. 1 to 7.

[0127] 8, in step 801, a processor of the aerosol generating device (e.g., processor 710 of FIG. 7) detects the type of aerosol product contained in a container (e.g., container 100i of FIG. 1) using a sensor (e.g., sensor 750 of FIG. 7). For example, the processor detects the type of aerosol product contained in the container by detecting a change in the electrical characteristics inside the container, which is detected differently depending on the type of aerosol product contained in the container.

[0128] In step 802, the processor determines whether the first aerosol product item has been received.

[0129] If it is determined in step 802 that the first aerosol product product is accommodated in the aerosol product accommodation unit, the processor controls in step 803 to supply first power from a battery (e.g., battery 720 in FIG. 7 ) to a coil (e.g., coil 730 in FIG. 7 ) so that a heating element (e.g., heating element 740 in FIG. 7 ) generates heat according to a first temperature profile, thereby allowing the aerosol generating device to maintain the aerosol quality of the first aerosol product at an optimum state.

[0130] Alternatively, if it is determined in step 802 that the first aerosol product is not contained in the aerosol product container, the processor determines in step 804 whether a second aerosol product is contained.

[0131] If it is determined in step 804 that a second aerosol product is contained in the aerosol product container, the processor controls the battery to supply second power to the coil so that the heating element generates heat according to a second temperature profile in step 805. This allows the aerosol generating device to maintain optimal aerosol quality of the second aerosol product.

[0132] Although not shown in the drawing, if it is determined that the second aerosol product is not contained in the aerosol product container in step 804, the processor determines whether a third aerosol product is contained in the aerosol product container. If it is determined that the third aerosol product is contained in the aerosol product container, the processor supplies third power from the battery to the coil so that the heating element generates heat according to a third temperature profile, and the aerosol generating device maintains the aerosol quality of the third aerosol product in an optimal state.

The display unit 1032 is, for example, a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), etc. The display unit 1032 may also be in the form of an LED light emitting element.

[0142] The haptic unit 1034 converts an electrical signal into a mechanical or electrical stimulus to tactilely provide the user with information about the aerosol generating device 100.

[0143] The acoustic output unit 1036 audibly provides the user with information about the aerosol generation device 100. For example, the acoustic output unit 1036 converts an electrical signal into an acoustic signal and outputs it to the outside.

[0144] The battery 1040 supplies power used to operate the aerosol generation device 100. The battery 1040 supplies power to heat the heater 1050. The battery 1040 also supplies power necessary for the operation of other components included in the aerosol generation device 100 (e.g., the sensing unit 1020, the output unit 1030, the user input unit 1060, the memory 1070, and the communication unit 1080). The battery 1040 is a rechargeable battery or a disposable battery. For example, the battery 1040 may be a lithium polymer (LiPoly) battery, but is not limited thereto.

Although not shown in Fig. 10, the aerosol-generating device 100 may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of the battery 1040 and supplies it to the heater 1050. Furthermore, when the aerosol-generating device 100 generates aerosol by an induction heating method, the aerosol-generating device 100 may further include a DC / AC converter that converts the DC power supply of the battery 1040 into AC power supply.

[0146] The processor 1010, the sensing unit 1020, the output unit 1030, the user input unit 1060, the memory 1070, and the communication unit 1080 perform their functions by receiving power from a battery 1040.

[0147] In one embodiment, the heater 1050 may be formed of 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. Additionally, the heater 130 may be embodied 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.

[0148] In another embodiment, heater 1050 is an induction heater, for example, heater 1050 includes a susceptor that generates heat through a magnetic field applied by a coil to heat the aerosol-generating material.

[0149] The user input unit 1060 receives information input by a user or outputs information to a user. For example, the user input unit 1060 may be, but is not limited to, a keypad, a dome switch, a touchpad (such as a contact capacitance type, a pressure type resistive film type, an infrared sensing type, a surface ultrasonic conduction type, an integral type tension measurement type, or a piezoelectric effect type), a jog wheel, or a jog switch. Although not shown in FIG. 10 , the aerosol generating device 100 may further include a connection interface such as a USB (universal serial bus) interface, through which the aerosol generating device 100 can connect to other external devices to send and receive information or charge the battery 1040.

[0150] The memory 1070 is hardware that stores various data processed within the aerosol generating device 100, and stores data that has been processed by the processor 1010 and data to be processed by the processor 1010.

[0154] The processor 1010 controls the overall operation of the aerosol generating device 100. The processor 1010 may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor 1010 and a memory storing a program executed by the microprocessor 1010. Those skilled in the art will understand that the processor 1010 may also be implemented as other types of hardware.

[0155] The processor 1010 controls the temperature of the heater 1050 by controlling the supply of power from the battery 1040 to the heater 1050.

In another example, a heating direct circuit may control the power supply to the heater 1050 in accordance with a control command from the processor 1010.

[0156] The processor 1010 analyzes the results sensed by the sensing unit 1020 and controls subsequent processing.
