Description

[Technical field]

[0001] The present invention relates to an aerosol generating device and a system thereof, and more particularly to an aerosol generating device capable of efficiently heating a miniaturized susceptor. [Background technology]

[0002] Recently, there has been an increasing demand for an alternative method to overcome the shortcomings of conventional cigarettes. For example, instead of a method of generating aerosol by burning a cigarette, there has been an increasing demand for a system that generates aerosol by heating a cigarette or an aerosol generating material using an aerosol generating device. As a result, research on heated aerosol generating devices has been actively conducted.

[0003] Recently, an induction heating type aerosol generator has been proposed that generates an aerosol by heating a cigarette or an aerosol generating material through an alternating magnetic field. In particular, the induction heating type aerosol generating device includes a coil that generates an alternating magnetic field when power is supplied thereto, and a susceptor that generates heat when the alternating magnetic field generated by the coil is applied, and the aerosol generating product is heated through the heat generated by the susceptor, thereby generating an aerosol from the aerosol generating material. Summary of the Invention [Problem to be solved by the invention]

[0004] An inductively heated aerosol generator includes a susceptor and a coil, the susceptor being heated by a magnetic field generated by the coil, thereby transferring thermal energy to the aerosol product.

[0005] Recently, there has been an increasing trend to miniaturize aerosol generating devices in order to improve portability and convenience for users. In order to miniaturize an inductively heated aerosol generating device, it is necessary to miniaturize the susceptor and / or coil that heats the aerosol product. For example, the susceptor can be miniaturized as a thin, spread metal film.

[0006] However, the coil used in the conventional induction heating aerosol generating device is formed in a spiral solenoid shape in which a current-carrying conductor is wound many times at predetermined intervals along the longitudinal direction of an imaginary cylinder. In such a coil, the ratio of the magnetic field generated by the coil that passes through the space where the susceptor is not present increases as the susceptor becomes smaller, so that the susceptor cannot be heated sufficiently and the aerosol product cannot be heated efficiently.

[0007] The problem to be solved through the embodiments of the present disclosure is to provide a heating means capable of efficiently heating a miniaturized susceptor, and an aerosol generating device and an aerosol generating system including the heating means.

[0008] Another problem to be solved through the embodiments of the present disclosure is to provide an aerosol generating device and an aerosol generating system that include a heating means including multiple coils connected together, but that can efficiently control the heating means so that the magnetic fields generated by the multiple coils are not canceled out.

[0009] The problems to be solved through the present embodiment are not limited to the problems mentioned above, and problems not mentioned will be clearly understood by a person having ordinary skill in the art to which the present embodiment pertains from this specification and the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The terms used in this embodiment are currently widely used general terms as much as possible, taking into consideration the functions in this disclosure, but they may vary depending on the intentions of the engineers in this field, precedents, or the emergence of new technologies. In addition, in certain cases, the applicant may arbitrarily select terms, and in such cases, the meanings of the terms will be described in detail in the description of the invention. Therefore, the terms used in this disclosure must be defined based on the meanings of the terms and the overall content of this disclosure, rather than simply the names of the terms.

[0017] Throughout the specification, when a part "includes" a certain component, it does not mean excluding other components, but also means including other components, unless otherwise specified to the contrary. Furthermore, terms such as "... unit" and "... module" in the specification mean a unit that processes at least one function or operation, which may be realized by hardware or software, or a combination of hardware and software.

[0018] As used herein, phrases such as "at least one of," when preceding an array of components, modify the entire array and not each individual component of the array. For example, the phrase "at least one of a, b, and c" should be interpreted to include a, b, c, a and b, a and c, b and c, or a, b, and c.

[0019] In one embodiment, the aerosol generating device is also a device that electrically heats a cigarette contained in the interior space to generate an aerosol.

[0020] The aerosol generating device also includes a heater, in one embodiment the heater is an electrically resistive heater, for example the heater may include a conductive track, such that the heater can be heated when a current is passed through the conductive track.

[0021] Heaters may include tubular, plate, needle or rod heating elements, and depending on the configuration of the heating element, may heat the interior or exterior of the cigarette.

[0022] Cigarettes also include tobacco rods and filter rods. The tobacco rods can be made of sheets, strands, or cut tobacco into finely cut tobacco sheets. The tobacco rods can also be surrounded by a heat conductive material. For example, the heat conductive material can be a metal foil, such as, but not limited to, aluminum foil.

[0023] The filter rod is also a cellulose acetate filter. The filter rod may be composed of at least one or more segments. For example, the filter rod may include a first segment for cooling the aerosol and a second segment for filtering a predetermined component contained in the aerosol.

[0024] In another embodiment, the aerosol generating device is also a device that utilizes a cartridge that holds an aerosol generating material to generate the aerosol.

[0025] The aerosol generating device also includes a cartridge that holds an aerosol generating material and a main body that supports the cartridge. The cartridge may be detachably coupled to the main body, but is not limited thereto. The cartridge may be formed integrally with or incorporated into the main body and fixed so as not to be detached by a user. The cartridge may be attached to the main 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 coupled to the main body.

[0026] The cartridge may hold an aerosol generating material in any one of a variety of states, such as a liquid state, a solid state, a gas state, or a gel state. The aerosol generating material may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing material including a volatile tobacco flavor component, or a liquid containing a non-tobacco material.

[0027] The cartridge can perform a function of converting the phase of the aerosol generating material inside the cartridge into a gas phase and generating an aerosol by being operated by an electric signal or a wireless signal transmitted from the main body. The aerosol can refer to a gas in which vaporized particles generated from the aerosol generating material and air are mixed.

[0028] In yet another embodiment, the aerosol generating device heats a liquid composition to generate an aerosol, which can be transmitted through the cigarette to the user, i.e., the aerosol generated from the liquid composition can travel along an airflow passage of the aerosol generating device, which airflow passage can be configured to transmit the aerosol through the cigarette to the user.

[0029] In still another embodiment, the aerosol generating device is a device that generates an aerosol from an aerosol generating material using an ultrasonic vibration method. In this case, the ultrasonic vibration method may mean a method of generating an aerosol by atomizing the aerosol generating material using ultrasonic vibration generated by a vibrator.

[0030] The aerosol generating device may include a vibrator, and may generate short-period vibrations through the vibrator to atomize the aerosol generating material. The vibrations generated by the vibrator may be ultrasonic vibrations, and the frequency band of the ultrasonic vibrations may be, but is not limited to, about 100 kHz to about 3.5 MHz.

[0031] The aerosol generating device may further include a wick for absorbing the aerosol generating material, for example, the wick may be positioned to surround or contact at least a region of the transducer.

[0032] When a voltage (e.g., an AC voltage) is applied to the transducer, heat and / or ultrasonic vibrations are generated from the transducer, and the heat and / or ultrasonic vibrations generated from the transducer can be transferred to the aerosol generating substance absorbed in the wick. The aerosol generating substance absorbed in the wick can be converted into a gas phase by the heat and / or ultrasonic vibrations transmitted from the transducer, resulting in the generation of an aerosol.

[0033] For example, the viscosity of the aerosol-generating material absorbed into the core is reduced by heat generated from the vibrator, and the reduced-viscosity aerosol-generating material is broken down into fine particles by ultrasonic vibrations generated from the vibrator, thereby generating an aerosol, but this is not limited to this.

[0034] In yet another embodiment, the aerosol generating device further comprises a cradle.

[0035] 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, or the heater may be heated when the cradle and the aerosol generating device are combined.

[0036] Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that a person having ordinary skill in the art can easily carry out the embodiments. The present disclosure may be embodied in the aerosol generating device of the above-mentioned various embodiments, or may be embodied in various different forms, but is not limited to the embodiments described herein.

[0037] The extension direction of a certain element means the direction in which the length of the element extends.

[0038] In one embodiment, the aerosol generating device is also a device that generates an aerosol by heating an aerosol product contained in the aerosol generating device by induction heating.

[0039] The induction heating method may refer to a method in which an alternating magnetic field is applied to generate heat from a magnetic material.

[0040] When an alternating magnetic field is applied to a magnetic material, energy loss due to eddy current loss and hysteresis loss may occur in the magnetic material. The lost energy may be released from the magnetic material as thermal energy. The greater the amplitude or frequency of the alternating magnetic field, the more thermal energy may be released from the magnetic material.

[0041] The induction heating type aerosol generating device also includes a susceptor and a coil. Optionally, the susceptor may be disposed inside the aerosol product. Alternatively, the susceptor may be disposed outside the aerosol product adjacent to the aerosol product. When power is supplied to the coil, the coil generates a magnetic field, and the coil can apply the magnetic field to the susceptor.

[0042] Alternatively, the susceptor may be a magnetic material that generates heat when an external magnetic field is applied. Alternatively, the susceptor may be a non-magnetic metal. When a magnetic field is applied to the susceptor disposed inside the coil, the susceptor generates heat and may heat the aerosol product.

[0043] In one embodiment, the coil may be formed in the shape of a helical solenoid, with a current-carrying wire wound many times at predetermined intervals along the length of an imaginary cylinder.

[0044] When a current flows through a solenoid coil, a magnetic field can be generated that passes through the space inside the coil. According to Ampere's law, the direction of the magnetic field generated by a current flowing through a solenoid coil is parallel to the central axis of an imaginary cylinder that the coil surrounds. The strength of the magnetic field generated by a current flowing through the solenoid coil is uniform regardless of the position in the space inside the coil, and is proportional to the number of turns of the coil per unit length and the strength of the current flowing through the coil.

[0045] In one embodiment, a virtual cylindrical space is formed inside the solenoid coil, and a container for containing at least a part of the aerosol product may be disposed in the space, in which a magnetic field is generated in the same direction as the extension direction of the container, and the magnetic field can pass through the aerosol product contained inside the container.

[0046] The strength of the magnetic field generated by passing a current through the solenoid coil is uniform regardless of position in the internal space surrounded by the coil, so that the magnetic field is applied uniformly throughout the container and the aerosol product, i.e., the magnetic field generated by the solenoid coil is not concentrated at a specific position but is formed uniformly throughout the entire internal space.

[0047] The smaller the susceptor placed inside the solenoid-shaped coil, the greater the proportion of the magnetic field generated by the coil that passes through space where there is no susceptor, and the lower the proportion of the magnetic field applied to the susceptor. As a result, the strength of the magnetic force applied to the susceptor becomes weaker, and the thermal energy release of the susceptor is reduced compared to the current flowing through the coil, which can result in poor energy efficiency.

[0048] For example, if the susceptor is in the form of a thin film that spreads in the direction in which the container extends, most of the magnetic field that passes through the internal space surrounded by most of the coil passes through space where there is no susceptor, and the proportion of the magnetic field that passes through the susceptor in the magnetic field generated by the coil becomes very low, which means that the susceptor will not be heated sufficiently and the aerosol product will not be heated efficiently.

[0049] The aerosol generating apparatus according to the present disclosure is intended to solve the problems described above, and to disclose an induction heating type aerosol generating apparatus capable of efficiently heating a miniaturized susceptor.

[0050] Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that a person having ordinary skill in the art can easily carry out the embodiments. The present disclosure may be embodied in the aerosol generating device of the above-mentioned various embodiments, or may be embodied in various different forms, but is not limited to the embodiments described in the present disclosure.

[0051] FIG. 1 is a cross-sectional view for explaining an aerosol generating device 10 and an aerosol product 20 according to the present disclosure.

[0052] 1, the aerosol generating device 10 includes a container 11, a heating means 12, a battery 13, and a control unit 14. However, the aerosol generating device 10 is not limited to these elements, and may further include other elements in addition to the elements illustrated in FIG.

[0053] The aerosol generating device 10 also includes a housing that forms the overall appearance of the aerosol generating device 10. An internal space may be formed inside the housing in which components of the aerosol generating device 10 may be disposed. For example, the internal space of the housing may accommodate a container 11, a heating means 12, a battery 13, and / or a control unit 14, but is not limited thereto.

[0054] The structure in which the storage section 11, the heating means 12, the battery 13 and the control section 14 are arranged inside the housing shown in FIG. 1 is one embodiment of the present disclosure, and the arrangement structure of the housing, the storage section 11, the heating means 12, the battery 13 and the control section 14 may be changed according to this embodiment.

[0055] The storage section 11 can store at least a portion of an aerosol product that can generate an aerosol. The storage section 11 can be formed in a cylindrical shape with a space formed therein for storing the aerosol product. The storage section 11 also includes an opening that opens to the outside of the aerosol generation device 10 to store the aerosol product 20. The opening of the storage section 11 can be opened to the outside of the aerosol generation device 10.

[0056] The aerosol production item 20 can be accommodated in the accommodation section 11 by being moved or inserted from the outside of the accommodation section 11 toward the inside of the accommodation section 11 through the opening of the accommodation section 11 .

[0057] A more detailed description of the aerosol producing article 20 is provided below with reference to FIG.

[0058] The heating means 12 is formed of one conductor and can generate a magnetic field by receiving power from a battery 13. At least a part of the conductor constituting the heating means 12 can form a coil 121 that generates a magnetic field. In this case, a plurality of coils 121 can be formed.

[0059] The specific shape of the heating means 12 and examples relating to the formation of a magnetic field will be described in more detail below with reference to other drawings.

[0060] The battery 13 may provide the power used to operate the components of the aerosol generating device 10.

[0061] In one example, the battery 13 may supply power such that an alternating current may be applied to the heating means 12. For example, the battery 13 may be electrically connected to the heating means 12 via a first power supply line 123-1 and a second power supply line 123-2 and may supply power to the heating means 12.

[0062] In another example, the battery 13 may supply power necessary for the operation of the control unit 14. The battery 13 may also supply power necessary for the operation of a display, a sensor, a motor, and the like provided in the aerosol generating device 10.

[0063] The control unit 14 can generally control the operation of the aerosol generation device 10. Specifically, the control unit 14 controls the operation of not only the heating means 12 and the battery 13 but also other components included in the aerosol generation device 10. The control unit 14 can also check the state of each component of the aerosol generation device 10 and determine whether the aerosol generation device 10 is in an operable state.

[0064] The control unit 14 also includes at least one processor. The processor may be realized by an array of a number of logic gates, or may be realized by a combination of a general-purpose microprocessor and a memory in which a program that can be executed by the microprocessor is stored. It will be understood by a person having ordinary skill in the art to which the present embodiment pertains that the processor may also be realized by other types of hardware.

[0065] The control unit 14 can control the power supplied from the battery 13 to the heating means 12. The operation of the control unit 14 will be described below with reference to FIG.

[0066] FIG. 2 is a diagram for explaining the shapes of the coil 121, the coil connector 122, and the power supply line 123 constituting the heating means 12 of the aerosol generating device 10 according to one embodiment.

[0067] The heating means 12 may be formed of a single continuous conductor. The heating means 12 may include one or more coils 121 that generate a magnetic field. The heating means 12 may include a plurality of coils 121, but in FIG. 2, only one coil 121 is shown in order to explain the specific shape of the heating means 12.

[0068] The heating means 12 is a single component through which current flows, but by being formed in a specific shape, each part can perform the required function, and therefore each part of the conductor that makes up the heating means 12 can be given a separate name.

[0069] The conductor forming the heating means 12 can be divided into a coil 121 , a coil connecting portion 122 , and a power supply line 123 .

[0070] The coil 121 may be formed in a shape in which a conductor through which a current can flow is wound many times. Unlike a solenoid-shaped coil in which an imaginary cylinder is wound many times with the same diameter, the coil 121 according to the present embodiment may be formed in a shape in which the diameter gradually increases as the coil is wound many times around an imaginary central axis.

[0071] The coil 121 can form a curved surface. The coil 121 can be disposed such that the curved surface formed by the coil 121 covers and surrounds at least a portion of the outer circumferential surface of the housing portion.

[0072] The coil connection part 122 is a conductor that electrically connects the plurality of coils 121 to each other. In FIG. 2, the coil connection part 122 is illustrated as being extended from the innermost conductor of the coil 121, but this is merely an example, and the coil connection part 122 may be configured in various shapes capable of connecting the coils 121 to each other.

[0073] The power supply line 123 is a conductor that receives power from a battery and supplies power to the coil 121. In FIG. 2, the power supply line 123 is illustrated as being extended from the outermost conductor of the coil 121, but this is merely an example, and the power supply line 123 may be configured in various forms that can connect the battery and the coil 121.

[0074] FIG. 3 is a diagram for explaining the relative positional relationship and arrangement between the container 11 and the heating means 12 of the aerosol generating device according to one embodiment.

[0075] The heating means 12 may be disposed outside the housing portion 11. The heating means 12 may also include one or more coils 121 that generate a magnetic field M. Since the heating means 12 is formed by one conductor, the multiple coils 121 may be electrically connected to each other.

[0076] The coil 121 may be disposed along the outer circumferential surface of the housing 11. The coil 121 may be disposed so that an imaginary central axis about which the coil 121 is wound crosses the extension direction (or the "longitudinal direction") of the housing 11. For example, the coil 121 may be disposed so that an imaginary central axis about which the coil 121 is wound is perpendicular to the extension direction of the housing 11, but the arrangement structure of the coil 121 is not limited thereto.

[0077] The coil 121 is curved into a shape corresponding to the outer circumferential surface of the accommodating portion 11, and can cover a part of the outer circumferential surface of the accommodating portion 11. The coil 121 can be disposed so as to maintain a constant distance from the outer circumferential surface of the accommodating portion 11 at any point on the coil 121. The center point around which the coil 121 is wound can be disposed at one point on the outer circumferential surface of the accommodating portion 11.

[0078] The coil 121 is electrically connected to a battery through a pair of power supply lines 123, and can receive current from the battery. The power supply lines 123 also include a first power supply line 123-1 and a second power supply line 123-2.

[0079] The coils 121 are electrically connected to each other through the coil connecting portion 122, and current is supplied to each of the coils 121 through the two power supply lines 123, so that the heating means 12 can be formed as a single conductor. The aerosol generating device according to the embodiment can reduce the manufacturing cost of the power supply configuration and improve the space utilization of the aerosol generating device through a structure in which the coils 121 are electrically connected to each other through the coil connecting portion 122 and power is supplied to each of the coils 121 through the two power supply lines 123. For example, in the case of an aerosol generating device including a structure in which power is supplied to each of the coils 121, a power supply line corresponding to the number of coils is required, whereas the aerosol generating device according to the embodiment can supply power to each of the coils 121 through only two power supply lines 123 or a pair of power supply lines 123, so that the manufacturing cost of the power supply lines and the mounting space of the power supply lines inside the aerosol generating device can be reduced. With such a configuration, since the multiple coils 121 do not need to be individually powered, the amount of material required to power the multiple coils 121 is reduced, the manufacturing costs of the coils 121 are reduced, and the space inside the aerosol generating device can be utilized more efficiently.

[0080] The heating means 12 may be disposed such that a virtual central axis around which the coil 121 is wound crosses the extension direction of the housing 11. With such an arrangement, according to Ampere's law, the magnetic field M generated by the heating means 12 can pass through the housing 11 crossing the extension direction of the housing 11. At this time, the angle between the direction in which the magnetic field M passes through the inside of the housing 11 and the direction in which the housing 11 extends can be approximately a right angle. The action of the magnetic field M inside the housing 11 will be described in more detail below with reference to FIG. 4.

[0081] Fig. 4 and Fig. 5 are cross-sectional views for explaining the action of the heating means of the aerosol generating device according to one embodiment. Fig. 4 is a cross-sectional view of the storage unit 11 of the aerosol generating device according to one embodiment, seen from a certain distance in the radial direction of the storage unit 11. Fig. 5 is a cross-sectional view of the storage unit 11 of the aerosol generating device according to one embodiment, seen from a certain distance in the extension direction of the storage unit 11.

[0082] 4 and 5, a susceptor for heating the aerosol product may be accommodated in the internal space of the accommodation unit 11. The susceptor may be arranged both inside and outside the aerosol product.

[0083] According to Ampere's law, the direction of the magnetic field generated by coil 121 is the same as the direction of the central axis around which coil 121 is wound.

[0084] In order for the coil 121 to generate the magnetic field M, an alternating current may be applied to the coil 121. The resonant frequency of the alternating current applied to the coil 121 may be 1 MHz or more and 10 MHz or less. An "X" shown on the cross section of the conductor constituting the coil 121 in FIGS. 4 and 5 indicates a state in which a current is entering the coil 121 when the cross section is viewed, and a "·" on the cross section of the conductor indicates a state in which a current is exiting the coil 121 when the cross section is viewed. When an alternating current is applied to the coil 121, the direction of the current flowing through the coil 121 changes continuously depending on the period of the alternating current, so the directions of the current shown in FIGS. 4 and 5 may be regarded as illustrating a temporary state at a particular point in time.

[0085] When an alternating current is applied to the coil 121, the direction of the magnetic field M generated by the coil 121 may change periodically according to the period of the alternating current. Therefore, the magnetic field directions illustrated in Figures 4 and 5 can be regarded as illustrating temporary states at a particular point in time.

[0086] The coil 121 may be disposed such that the central axis around which the coil 121 is wound is perpendicular to the extension direction of the housing unit 11. With such an arrangement, the magnetic field M formed by the coil 121 may pass through the internal space of the housing unit 11 in a direction perpendicular to the extension direction of the housing unit 11, and may pass through a susceptor accommodated in the internal space of the housing unit 11, thereby heating the susceptor.

[0087] According to an embodiment, the susceptor may be formed in the shape of a thin film. When the susceptor is in the form of a thin, spread-out thin film, the heat generation efficiency relative to the volume occupied by the susceptor or the mass of the susceptor is maximized, and power efficiency may be improved. In addition, the volume occupied by the susceptor is reduced, and the space of the aerosol generation device 10 may be used more efficiently. The thickness of the miniaturized susceptor is 1 μm or more and 100 μm or less.

[0088] The susceptor may be arranged so that the direction in which the susceptor extends is the same as the direction in which the housing portion 11 extends. With such an arrangement, the direction of the magnetic field M generated by the coil 121 crosses the direction in which the susceptor extends, so that the density of the magnetic field M passing through the susceptor is increased, and the heating efficiency of the susceptor may be improved compared to the case in which a solenoid-shaped coil is applied.

[0089] In other words, according to this embodiment, even when the susceptor is miniaturized into a thin film that spreads thinly in the longitudinal direction of the storage section 11, the magnetic field generated by the coil 121 can pass through a wide area of ​​the susceptor, so that a magnetic field of sufficient density is applied to the susceptor, and the susceptor can heat the aerosol product 20 to a sufficient temperature.

[0090] Unlike a solenoid-shaped coil, in an aerosol generating device 10 according to one embodiment of the present disclosure, the direction of the magnetic field M is transverse to the longitudinal direction of the storage section 11, so that the density of the magnetic field passing through the susceptor is increased, thereby improving the heating efficiency of the susceptor compared to when a solenoid-shaped coil is applied.

[0091] The susceptor may be a non-magnetic metal such as aluminum. In the case of such non-magnetic metals, sufficient heat is not generated due to the resonant frequency due to the characteristics of low resistivity and relative magnetic permeability. When the susceptor is made of a non-magnetic metal and an alternating current is applied to the heating means 12, the resonant frequency of the alternating current applied to the coil 121 may be required to be 1 to 10 MHz in order for the susceptor to generate sufficient heat. The coil 121 may be formed to have a length, diameter, and material that allows the resonant frequency to be 1 to 10 MHz when an alternating current is applied.

[0092] The susceptor may include a metal or carbon. The susceptor may include at least one of ferrite, ferromagnetic alloy, stainless steel, and aluminum (Al). The susceptor may also include at least one of graphite, molybdenum, silicon carbide, niobium, nickel alloy, metal film, ceramics such as zirconia, transition metals such as nickel (Ni) and cobalt (Co), and semi-metals such as boron (B) and phosphorus (P).

[0093] The coils 121 may have the same size and shape, and at least some of the coils 121 may be arranged symmetrically with respect to the receiving portion 11 .

[0094] At least some of the coils 121 may be disposed to face each other across the receiving portion 11. At least some of the coils 121 may be disposed to be spaced apart from each other at regular intervals.

[0095] In this case, when some of the coils 121 among the multiple coils 121 are arranged symmetrically with respect to the central axis of the housing part 11, the magnetic fields M generated by the coils 121 may be cancelled out depending on the winding direction of each coil 121 and the direction of the current flowing through the coils 121. If the magnetic fields M generated by the coils 121 are cancelled out, a situation may arise in which the heating efficiency of the heating means 12 is reduced.

[0096] 4 and 5, in the aerosol generating device according to an embodiment, two coils 121 may be arranged symmetrically facing each other with respect to the receiving part 11. In this case, the two coils 121 may be arranged to have the same central axis and the same winding direction (clockwise or counterclockwise).

[0097] With such an arrangement, the direction of current flowing through each coil 121 (clockwise or counterclockwise) is the same, and the direction of the magnetic field M generated by each coil 121 is the same. Therefore, the magnetic fields M generated by each coil 121 having the same central axis are not canceled out but are superimposed and further strengthened, thereby improving the efficiency of heating the susceptor.

[0098] At least a portion of the conductor constituting one coil 121 among the multiple coils may be formed in a circular shape with a constant radius based on a central axis around which the coil 121 is wound. The coil 121 may also have a shape of concentric circles with several circular conductors with different radii arranged. The spacing between the conductors constituting one coil 121 is also constant, so that the density of the magnetic field M generated by the coil 121 is uniform and heat generation by the coil 121 may be minimized.

[0099] However, the shape of the coil 121 is not limited to a circular shape, and the number, size, and shape of the coil 121 may be modified as necessary. For example, the coil 121 may have a rectangular shape when viewed along the central axis of the coil 121, and four coils 121 may be arranged spaced apart from each other at equal intervals.

[0100] Since the magnetic field M generated by the coil 121 has a high magnetic flux density at the center where the coil 121 is wound, there is a concern that a portion of the aerosol product 20 inserted in the container 11 adjacent to the center where the coil 121 is wound may be heated to a relatively high temperature compared to other portions. If multiple coils 121 are provided, the centers where the coils 121 are wound are disposed at multiple points on the outer surface of the container 11, so that the aerosol product 20 contained in the container 11 can be heated uniformly.

[0101] The temperature of the susceptor heated by the magnetic field M can be changed by changing the amplitude or frequency of the alternating current flowing through the coil 121. The control unit can control the power supplied to the heating means 12 and adjust the magnetic field M formed by the coil 121, thereby controlling the temperature of the susceptor.

[0102] As an example, the coil 121 may include, but is not limited to, copper. The coil 121 may include any one of silver (Ag), gold (Au), aluminum (Al), tungsten (W), zinc (Zn) and nickel (Ni), or an alloy including at least one of them, so as to have a low resistivity and thus a high current flow.

[0103] The accommodation portion 11 also includes a protrusion 111 formed at a position corresponding to the center around which the coil 121 arranged on the outer circumferential surface of the accommodation portion 11 is wound. The protrusion 111 protrudes radially outward from the accommodation portion 11 in at least one region of the outer circumferential surface of the accommodation portion 11, and can support the heating means 12. As an example, the protrusion 111 is arranged at the center of the coil 121 and can support the coil 121.

[0104] The number of protrusions 111 may correspond to the number of coils 121. The shape of the protrusions 111 may correspond to the shape of the coils 121 and may be formed into a shape suitable for supporting the coils 121. For example, the protrusions 111 may have a protruding rectangular shape or a protruding circular shape.

[0105] FIG. 6 is a diagram illustrating an example of an aerosol product 20.

[0106] The aerosol production item 20 is a component that can be contained inside the above-mentioned container 11. The aerosol production item 20 can be heated by heating means 12.

[0107] 6, the aerosol product 20 includes a tobacco rod 21 and a filter rod 22. In FIG. 6, the filter rod 22 is illustrated as a single segment, but is not limited thereto. In other words, the filter rod 22 may be composed of multiple segments.

[0108] For example, the filter rod 22 may include a first segment that cools the aerosol and a second segment that filters a certain component contained in the aerosol, and optionally, the filter rod 22 may further include at least one segment that performs another function.

[0109] The aerosol product 20 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 aerosol product 20 may be wrapped by one wrapper 24. As another example, the aerosol product 20 may be wrapped by two or more wrappers 24 in a superimposed manner. For example, the tobacco rod 21 may be wrapped by the first wrapper 24a, and the filter rod 22 may be wrapped by wrappers 24b, 24c, and 24d. Then, the entire aerosol product 20 may be further wrapped by a single wrapper 24e. If the filter rod 22 is composed of a plurality of segments, each segment may be wrapped by the wrappers 24b, 24c, and 24d.

[0110] The tobacco rod 21 includes an aerosol-generating material. For example, the aerosol-generating material 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. The tobacco rod 21 may also include other additives, such as flavoring agents, humectants, and / or organic acids. A flavoring liquid, such as menthol or a humectant, may be added to the tobacco rod 21 by being sprayed onto the tobacco rod 21.

[0111] The susceptor may be disposed inside the aerosol product article. As an example, the susceptor may be included in the tobacco rod 21. The susceptor may be disposed so as to surround at least a portion of the aerosol product article 20. The susceptor may be disposed so that the direction in which the susceptor extends is the same as the direction in which the aerosol product article 20 extends.

[0112] The tobacco rod 21 can be made in a variety of ways. For example, the tobacco rod 21 can be made in the form of a sheet or a strand.

[0113] The tobacco rod 21 may also be made from cut tobacco, which is a tobacco sheet that has been finely shredded.

[0114] Although not shown in FIG. 6, the aerosol production article 20 also includes a susceptor.

[0115] The susceptor included in the tobacco rod 21 may be formed in various shapes. For example, the susceptor may be formed in the form of a sheet and surround the exterior of the tobacco rod 21. As another example, the susceptor may be formed in the form of strands or particles, and a plurality of susceptors may be distributed within the tobacco rod 21.

[0116] The tobacco rod 21 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. As an example, the thermally conductive material surrounding the tobacco rod 21 may uniformly distribute the heat transferred to the tobacco rod 21, improve the thermal conductivity applied to the tobacco rod 21, and thereby improve the flavor of the aerosol generated from the tobacco rod 21. The thermally conductive material surrounding the tobacco rod 21 may also function as a susceptor that is heated by a magnetic field.

[0117] The filter rod 22 is also a cellulose acetate filter. 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 having a hollow inside. The filter rod 22 may also be a recessed rod. If the filter rod 22 is composed of multiple segments, at least one of the multiple segments may be made to have a different shape.

[0118] The filter rod 22 may be prepared to produce a flavor. For example, a flavoring liquid may be sprayed onto the filter rod 22, or a separate fiber coated with the flavoring liquid may be inserted into the filter rod 22.

[0119] The filter rod 22 also includes at least one capsule 23. Here, the capsule 23 can generate flavor or aerosol. For example, the capsule 23 is a structure in which a liquid containing a flavoring agent is covered with a coating. The capsule 23 can have a spherical or cylindrical shape, but is not limited thereto.

[0120] If the filter rod 22 includes a segment for cooling the aerosol, the cooling segment can be made of a polymeric material or a biodegradable polymeric material. For example, the cooling segment can be made of pure polylactic acid, but is not limited thereto. Alternatively, the cooling segment can be made of a cellulose acetate filter with multiple holes. However, the cooling segment is not limited to the above examples, and can be any material that can perform the function of cooling the aerosol without limitation.

[0121] Although not shown in Fig. 6, the aerosol production product 20 further includes a front end plug. The front end plug may be located on one side of the tobacco rod 21 opposite the filter rod 22. The front end plug may prevent the tobacco rod 21 from being detached to the outside, and may prevent the liquefied aerosol from flowing out of the tobacco rod 21 into the aerosol generation device 10 (Fig. 1).

[0122] 7 and 8 are diagrams for explaining an example in which the heating means 12 of the aerosol generation device 10 of the present disclosure includes four or more coils 121.

[0123] FIG. 7 is a diagram for explaining a state in which the heating means 12 including four coils 121 is disposed on the outer circumferential surface of the container 11 of the aerosol generation device 10. As shown in FIG.

[0124] FIG. 8 is a diagram illustrating a state in which the heating means 12 including four coils 121 is spread out on a flat surface.

[0125] The heating means 12 shown in FIGS. 7 and 8 is formed by one conducting wire, but also includes a first coil 121-1, a second coil 121-2, a third coil 121-3 and a fourth coil 121-4.

[0126] The first coil 121-1 and the second coil 121-2 may be connected by a first coil connection part 122-1, the second coil 121-2 and the third coil 121-3 may be connected by a second coil connection part 122-2, and the third coil 121-3 and the fourth coil 121-4 may be connected by a third coil connection part 122-3.

[0127] The first power supply line 123-1 and the second power supply line 123-2 can supply power to the multiple coils 121-1, 121-2, 121-3, and 121-4.

[0128] 7 and 8, the heating means 12 is formed by a single conductor, and multiple coils 121-1, 121-2, 121-3, and 121-4 are electrically connected by multiple coil connection portions 122-1, 122-2, and 122-3, and power is supplied to the heating means 12 only by two power supply lines 123-1 and 123-2.

[0129] The four coils 121-1, 121-2, 121-3, and 121-4 may be formed to have the same size and shape and may be spaced apart from each other at regular intervals, but are not limited thereto, and the number, size, and shape of the coils may be modified as necessary.

[0130] When a plurality of coils 121-1, 121-2, 121-3, and 121-4 are arranged, the magnetic fields formed by the coils arranged symmetrically with respect to the housing section 11 may cancel each other out.

[0131] In the example shown in FIG. 7, the first coil 121-1 and the third coil 121-3 are arranged symmetrically around the accommodating portion 11, and the second coil 121-2 and the fourth coil 121-4 are arranged symmetrically around the accommodating portion 11.

[0132] In Fig. 8, arrows indicate the direction of current flowing through each coil included in the heating means 12. When an AC current is applied to the heating means 12, the direction of the current continuously changes depending on the frequency of the AC current, so the direction of the current illustrated in Fig. 8 can be regarded as illustrating a temporary state at a specific point in time.

[0133] 8 is disposed so as to surround the outer circumferential surface of the receiving section 11, the first coil 121-1 and the third coil 121-3 may be disposed so as to face each other with the receiving section 11 at the center as shown in Fig. 7. With such an arrangement, the first coil 121-1 and the third coil 121-3 have the same coil winding direction, the same central axis around which the coil is wound, and the same rotation direction (clockwise or counterclockwise) of the current flowing through the coil.

[0134] Similarly, the second coil 121-2 and the fourth coil 121-4 are arranged facing each other around the accommodating section 11, and the second coil 121-2 and the fourth coil 121-4 have the same winding direction, the same central axis around which the coils are wound, and the same direction of current flowing through the coils (clockwise or counterclockwise).

[0135] With such an arrangement, even if the heating means 12 includes four or more integrally formed coils, the rate at which the magnetic fields cancel each other out can be minimized.

[0136] In addition, with such an arrangement, there is no need to control each coil separately to prevent the magnetic fields from canceling each other out, so there is an advantage that the magnetic fields generated by the multiple coils 121-1, 121-2, 121-3, and 121-4 are not canceled out by simply controlling one circuit system using the heating means 12 formed by a single conductor, making it easier to control the circuit system.

[0137] FIG. 9 is a block diagram of an aerosol generating device 10 according to one embodiment of the present disclosure.

[0138] The aerosol generation device 10 also includes a storage unit 11 (not shown), a heating means 12, a battery 13, a control unit 14, a sensing unit 15, an output unit 16, a communication unit 17, a memory 18, and a user input unit 19. However, the internal structure of the aerosol generation device 10 is not limited to that shown in Fig. 9.

For example, the insertion detection sensor 152 may include at least one of a film sensor, a pressure sensor, an optical sensor, a resistive sensor, a capacitive sensor, an inductive sensor, and an infrared sensor, and may detect a signal change due to the insertion and / or removal of the aerosol product. As an example, the insertion detection sensor 152 may detect the entry and exit of a susceptor inside the aerosol product, and may detect the insertion and / or removal of the aerosol product. In this case, the susceptor may serve both to heat the aerosol product and to serve as a sensing object for the aerosol product.

[0143] The puff sensor 153 may detect a user's puff based on various physical changes in the airflow passage or airflow channel, for example, the puff sensor 153 may detect a user's puff based on any one of a temperature change, a flow change, a voltage change, and a pressure change.

A person skilled in the art can intuitively infer the function of each sensor from its name, so a detailed description thereof may be omitted.

[0145] The output unit 16 may output information related to the state of the aerosol generating device 10 and provide it to a user. The output unit 16 may include at least one of a display unit 161, a haptic unit 162, and an audio output unit 163, but is not limited to them.

[0146] The display unit 161 may visually provide information related to the aerosol generating device 10 to a user. For example, the information related to the aerosol generating device 10 may mean various information such as a charging / discharging state of the battery 13 of the aerosol generating device 10, a preheating state of the heating means 12, an insertion / removal state of an aerosol product, or a state in which the use of the aerosol generating device 10 is restricted (e.g., abnormal item detection), and the display unit 161 may output the information to the outside. The display unit 161 may be, for example, a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), etc. Also, the display unit 161 may be in the form of a light emitting element such as an LED (light-emitting diode).

[0147] The haptic unit 162 can convert an electrical signal into a mechanical or electrical stimulus and provide a user with tactile information related to the aerosol generating device 10. For example, the haptic unit 162 can include a motor, a piezoelectric element, or an electrical stimulation device.

[0148] The acoustic output unit 163 can provide the user with audible information related to the aerosol generation device 10. For example, the acoustic output unit 163 can convert an electric signal into an acoustic signal and output it to the outside.

[0149] The battery 13 may supply power used for the operation of the aerosol generating device 10. The battery 13 may supply power so that the heating means 12 can be heated. The battery 13 may also supply power necessary for the operation of other components (e.g., the sensing unit 15, the output unit 16, the user input unit 19, the memory 18, and the communication unit 17) provided in the aerosol generating device 10. The battery 13 may be a rechargeable battery or a one-time use battery. For example, the battery 13 may be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0150] The heating means 12 can heat the susceptor and the aerosol product by receiving power from the battery 13. Although not shown in Fig. 9, the aerosol generation device 10 further includes a power conversion circuit (e.g., a DC (direct current) / DC converter) that converts the power of the battery 13 and supplies it to the heating means 12. When the aerosol generation device 10 heats the aerosol product by an induction heating method, the aerosol generation device 10 further includes a DC / AC (alternating current) converter that converts the DC power supply of the battery 13 into an AC power supply.

[0151] The control unit 14, the sensing unit 15, the output unit 16, the communication unit 17, the memory 18, and the user input unit 19 can perform their functions by receiving power from the battery 13. Although not shown in Fig. 9, the device further includes a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the battery 13 and supplies it to each of the components.

[0152] The user input unit 19 can receive information input by a user or output information to a user. For example, the user input unit 19 can be, but is not limited to, a key pad, a dome switch, a touch pad (contact type capacitance type, pressure type resistive film type, infrared sensing type, surface ultrasonic conduction type, integral type tension measurement type, piezoelectric effect type, etc.), a jog wheel, a jog switch, etc. In addition, although not shown in FIG. 9, the aerosol generating device 10 can further include a connection interface such as a USB (universal serial bus) interface, and can connect to another external device through the connection interface such as the USB interface to transmit and receive information or charge the battery 13.

[0153] The memory 18 is hardware that stores various data processed in the aerosol generating device 10, and can store data processed by the control unit 14 and data to be processed. The memory 18 includes at least one type of recording medium among a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., a secure digital (SD) memory or an extreme digital (XD) memory), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. The memory 18 can store the operation time of the aerosol generating device 10, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data related to the user's smoking pattern.

[0154] The communication unit 17 also includes at least one component for communication with other electronic devices. For example, the communication unit 17 also includes a short-range wireless communication unit 171 and a wireless communication unit 172.

[0157] The control unit 14 may control the overall operation of the aerosol generating device 10. In one embodiment, the control unit 14 may also include at least one processor. The processor may be realized by an array of a number of logic gates, or may be realized by a combination of a general-purpose microprocessor and a memory in which a program that can be executed by the microprocessor is stored. It will be understood by a person having ordinary skill in the art to which this embodiment pertains that the processor may also be realized by other types of hardware.

[0158] The control unit 14 can control the temperature of the aerosol product by controlling the supply of power from the battery 13 to the heating means 12. For example, the control unit 14 can control the power supply by controlling the switching of the switching elements between the battery 13 and the heating means 12. As another example, the heating direct circuit can control the power supply to the heating means 12 by a control command from the control unit 14.

[0159] The control unit 14 may analyze the results sensed by the sensing unit 15 and control the processes to be performed thereafter. For example, the control unit 14 may control the power supplied to the heating means 12 so that the operation of the heating means 12 is started or ended based on the results sensed by the sensing unit 15. As another example, the control unit 14 may control the amount of power supplied to the heating means 12 and the time for which the power is supplied so that the aerosol product is heated to a predetermined temperature or maintained at an appropriate temperature based on the results sensed by the sensing unit 15.

[0160] The control unit 14 may control the output unit 16 based on the result sensed by the sensing unit 15. For example, when the number of puffs counted through the puff sensor 153 reaches a preset number, the control unit 14 may notify the user through at least one of the display unit 161, the haptic unit 162, and the audio output unit 163 that the aerosol generating device 10 will soon be shut down.
