Description

Technical Field

[0001] Various embodiments relate to a cigarette cartridge and an aerosol generating device including the cigarette cartridge, and more particularly, to a cigarette cartridge using an induction heating method and an aerosol generating device including the cigarette cartridge. Background Art

[0002] Recently, the demand for alternative methods for overcoming the disadvantages of ordinary cigarettes has increased. For example, there is an increasing demand for systems for generating aerosols by heating cigarettes or aerosol generating materials using an aerosol generating device rather than by burning the cigarette. Therefore, research on heating-type aerosol generating devices has been actively conducted.

[0003] One of the various methods of heating the aerosol generating substance is an induction heating method. The induction heating method refers to a method of generating heat from a magnetic body by applying an alternating magnetic field to the magnetic body. Here, the alternating magnetic field may be referred to as an induction magnetic field.

[0004] When an alternating magnetic field is applied to a magnet, energy loss due to eddy current loss and hysteresis loss may occur in the magnetic body. The lost energy may be emitted from the magnet as heat energy. When the amplitude or frequency of the alternating magnetic field increases, a large amount of heat energy may be emitted from the magnetic body. Summary of the invention

[0005] Technical issues

[0006] Liquid cigarette cartridges may generally have a structure in which a core (e.g., cotton, silica, ceramic, etc.) for absorbing liquid is coupled to a heating element (e.g., a coil using a resistance heating principle) for atomizing liquid. Existing liquid cigarette cartridges may directly heat the heating element by receiving power through contact terminals. During direct heating through contact terminals, heat loss may occur at the contact terminals and the power supply line.

[0007] In addition, during direct heating through the contact terminals, both ends of the heating element need to be connected to the contact terminals. When multiple heating elements are arranged on each surface of the core, many contact terminals corresponding to the number of heating elements are required, and therefore, the internal structure of the cartridge may be complicated. In addition, it is difficult to arrange many heating elements in a limited space inside the cartridge.

[0008] In addition, during direct heating through the contact terminals, all portions of the heating element may not be uniformly heated, and thus, harmful substances may be generated due to carbonization of the core at a portion having a temperature higher than a target temperature.

[0009] The embodiment provides a cigarette cartridge including a susceptor heated by an induction magnetic field generated by an induction coil of a main body of an aerosol generating device, and an aerosol generating device including the cigarette cartridge.

[0010] In addition, embodiments provide a cartridge including one or more susceptors that may be arranged on respective surfaces of a core, and an aerosol generating device including the cartridge.

[0011] In addition, an embodiment provides a cartridge including a susceptor formed integrally with a core, the susceptor being capable of performing both functions of a core and a susceptor, and an aerosol generating device including the cartridge.

[0015] According to another aspect of the present disclosure, the cigarette cartridge includes: a storage unit, which is configured to store an aerosol generating substance; and a receptor formed as one piece with the core, which is arranged below the storage unit and is configured to: absorb the aerosol generating substance supplied from the storage unit, and atomize the aerosol generating substance absorbed from the storage unit into an aerosol generating substance by generating heat in response to an induced magnetic field.

[0016] According to another aspect of the present disclosure, an aerosol generating device includes a cartridge and a body, wherein the body includes an induction coil, and the coil is arranged below the cartridge to generate an induction magnetic field.

[0017] Advantageous Effects of the Invention

[0018] According to an embodiment, according to the cartridge and the aerosol generating device including the same, a separate contact terminal and a power supply line connecting the cartridge to a main body are not required, and thus, heat loss can be reduced and heating efficiency can be improved.

[0019] In addition, according to the embodiment, according to the cartridge and the aerosol generating device including the same, the degree of freedom of the arrangement structure of the heating element (susceptor) relative to the core can be improved, and the structure of the cartridge can be simplified.

In this case, the meaning of the terms will be described in detail in the corresponding parts in the description of the present disclosure. Therefore, the terms used in each embodiment of the present disclosure should be defined based on the meaning of the terms and the description provided herein.

[0037] In addition, unless explicitly described to the contrary, the word "include" and variations such as "including" or "comprising" will be understood to imply the inclusion of the elements but not the exclusion of any other elements. In addition, the terms "... device", "... part" and "module" described in the specification represent units for processing at least one function and operation, and can be implemented by hardware components or software components and a combination thereof.

[0038] As used herein, when an expression such as "at least any one" precedes an element disposed, it modifies all elements without modifying each disposed element. For example, the expression "at least any one of a, b, and c" should be interpreted as including: a, b, c, or a and b, a and c, b and c, or a, b and c.

[0039] In an embodiment, the aerosol generating device may be a device that generates aerosol by electrically heating a cigarette housed in an internal space of the device.

[0040] The aerosol generating device may comprise a heater. In an embodiment, the heater may be a resistive heater. For example, the heater may comprise an electrically conductive trace, and the heater may be heated when an electric current flows through the electrically conductive trace.

[0041] 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 according to the shape of the heating element.

[0042] The cigarette may include a tobacco rod and a filter rod. The tobacco rod may be formed by sheets, filaments and tiny crumbs cut from tobacco sheets. In addition, the tobacco rod may be surrounded by a heat-conducting material. For example, the heat-conducting material may be, but is not limited to, a metal foil, such as an aluminum foil.

[0043] The filter rod may include a cellulose acetate filter. The filter rod may include at least one section. For example, the filter rod may include: a first section configured to cool the aerosol and a second section configured to filter specific components in the aerosol.

[0044] In another embodiment, the aerosol generating device may be a device that generates an aerosol by using a cartridge containing an aerosol generating substance.

[0045] The aerosol generating device may include: a cartridge containing an aerosol generating substance; and a main body supporting the cartridge. The cartridge may be detachably connected to the main body, but is not limited thereto. The cartridge may be integrally formed or assembled with the main body, and may also be fixed to the main body so as not to be removed from the main body by the user. The cartridge may be mounted on the main body when the aerosol generating substance is accommodated in the main body. However, the present disclosure is not limited thereto. When the cartridge is connected to the main body, the aerosol generating substance may also be injected into the cartridge.

[0046] The cartridge may contain an aerosol-generating substance in any of a variety of states, such as a liquid, solid, gaseous, gel, etc. The aerosol-generating substance may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco substance having a volatile tobacco aroma component, or a liquid containing a non-tobacco substance.

[0047] The cartridge can be operated by an electrical signal or a wireless signal transmitted from the main body to perform the function of generating aerosol by converting the phase of the aerosol generating substance inside the cartridge into a gas phase. Aerosol can refer to a gas of vaporized particles generated by the aerosol generating substance mixed with air.

[0048] In another embodiment, the aerosol generating device can generate an aerosol by heating the liquid composition, and the generated aerosol can be delivered to the user through the cigarette. In other words, the aerosol generated by the liquid composition can move along the air flow channel of the aerosol generating device, and the air flow channel can be configured so that the aerosol is delivered to the user by passing through the cigarette.

[0049] In another embodiment, the aerosol generating device may be a device that generates aerosol from an aerosol generating substance by using an ultrasonic vibration method.

[0050] The aerosol generating device may include a vibrator, and generate short-period vibrations through the vibrator to convert the aerosol generating substance into an aerosol. The vibration generated by the vibrator may be ultrasonic vibration, and the frequency band of the ultrasonic vibration may be in the frequency band of about 100kHz to about 3.5MHz, but is not limited thereto.

[0051] The aerosol generating device may further comprise a core that absorbs the aerosol generating substance.For example, the core may be arranged to surround at least one region of the vibrator, or may be arranged to contact at least one region of the vibrator.

[0052] When a voltage (e.g., an AC voltage) is applied to the vibrator, heat and / or ultrasonic vibration may be generated by the vibrator, and the heat and / or ultrasonic vibration generated by the vibrator may be transferred to the aerosol-generating substance absorbed in the core. The aerosol-generating substance absorbed in the core may be converted into a gas phase by the heat and / or ultrasonic vibration transferred by the vibrator, and thus an aerosol may be generated.

[0053] For example, the viscosity of the aerosol generating substance absorbed in the core may be reduced by heat generated by the vibrator, and when the aerosol generating substance having reduced viscosity is granulated by ultrasonic vibration generated from the vibrator, aerosol may be generated, but is not limited thereto.

[0054] In another embodiment, the aerosol generating device is a device that generates an aerosol by heating an aerosol generating article housed in the aerosol generating device by induction heating.

[0055] The aerosol generating device may include a susceptor and a coil. In an embodiment, the coil may apply a magnetic field to the susceptor. When power is supplied from the aerosol generating device to the coil, a magnetic field may be formed inside the coil. In an embodiment, the susceptor may be a magnet that generates heat by an external magnetic field. When the susceptor is positioned inside the coil and a magnetic field is applied to the susceptor, the susceptor generates heat to heat the aerosol generating article. In addition, optionally, the susceptor may be positioned inside the aerosol generating article.

[0056] In another embodiment, the aerosol generating device may further comprise a bracket.

[0057] The aerosol generating device may form a system together with a separate cradle. For example, the cradle may charge a battery of the aerosol generating device. Alternatively, the heater may be heated when the cradle and the aerosol generating device are coupled to each other.

[0058] Hereinafter, the present disclosure will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are shown so that a person skilled in the art can easily implement the present disclosure. The present disclosure can be implemented in a form that can be implemented in the aerosol generating device of the various embodiments described above, or can be implemented in various different forms, and is not limited to the embodiments described herein.

[0059] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0060] Figures 1 to 3 is a diagram showing an example of an aerosol generating device.

[0061] Reference Figures 1 to 3 The aerosol generating device 1 may include a battery 11 , a controller 12 , a heater 13 and a vaporizer 14 .

[0062] Figure 1 and Figure 2 The aerosol generating device 1 comprises: a housing, the housing comprising a housing space, and the aerosol generating product 2 is housed in the housing space. The aerosol generating product 2 can be inserted into the aerosol generating device 1, and thus, the aerosol generating product 2 can be housed in the housing space of the housing. In addition, Figure 1 and Figure 2 The aerosol generating device 1 is shown to include a heater 13 , but the heater 13 may be omitted if desired.

[0063] Figure 3 The aerosol generating device 1 may not include a space into which the aerosol generating article 2 may be inserted, and therefore, the heater 13 for heating the aerosol generating article 2 may not be arranged.

[0064] Figures 1 to 3 The aerosol generating device 1 shown may only include components relevant to this embodiment. Figures 1 to 3 In addition to the components shown, the aerosol generating device 1 may also include other components.

[0065] Figure 1 The battery 11, the controller 12, the vaporizer 14 and the heater 13 are shown to be arranged in a straight line. Figure 2 As shown, the vaporizer 14 and the heater 13 may be arranged in parallel. However, the internal structure of the aerosol generating device 1 is not limited to Figures 1 to 3 In other words, the arrangement structures of the battery 11 , the controller 12 , the vaporizer 14 , and the heater 13 may be changed according to the design of the aerosol generating device 1 .

[0066] The battery 11 can supply power for operating the aerosol generating device 1. For example, the battery 11 can supply power so that the heater 13 or the vaporizer 14 can be heated, and can supply power required for the controller 12 to operate. In addition, the battery 11 can supply power required for the display, sensor, motor, etc. installed in the aerosol generating device 1 to operate.

[0067] The controller 12 may control the overall operation of the aerosol generating device 1. Specifically, the controller 12 may control the operation of the battery 11, the heater 13, and the vaporizer 14, and the controller 12 may also control the operation of other components included in the aerosol generating device 1. In addition, the controller 12 may determine whether the aerosol generating device 1 is in an operable state by identifying the state of each of the components of the aerosol generating device 1.

[0068] The controller 12 may include at least one processor. The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program that can be executed by the microprocessor. In addition, those skilled in the art of the present embodiment will understand that the processor may be implemented in other forms of hardware.

[0069] The heater 13 may be heated by the power supplied from the battery 11. For example, when the aerosol-generating article 2 is inserted into the aerosol-generating device 1, the heater 13 may be located outside the aerosol-generating article 2. Therefore, the heated heater 13 may increase the temperature of the aerosol-generating substance in the aerosol-generating article 2.

[0070] The heater 13 may be a resistive heater. For example, the heater 13 may include an electrically conductive trace, and the heater 13 may be heated when current flows through the electrically conductive trace. However, the heater 13 is not limited to the examples described above and the heater 13 may include all heaters that can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating device 1 or may be set to a desired temperature by a user.

[0071] As a further example, the heater 13 may include an induction heater. Specifically, the heater 13 may include an electrically conductive coil for heating the aerosol-generating article by induction heating, and the aerosol-generating article may include a susceptor that may be heated by the induction heater.

[0072] Figure 1 and Figure 2The heater 13 is shown to be arranged outside the aerosol generating article 2, but the heater 13 is not limited thereto. For example, the heater 13 may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and may heat the inside or outside of the aerosol generating article 2 according to the shape of the heating element.

[0073] In addition, the aerosol generating device 1 may include a plurality of heaters 130. Here, the plurality of heaters 130 may be inserted into the aerosol generating article 2 or may be arranged outside the aerosol generating article 2. In addition, some of the plurality of heaters 130 may be inserted into the aerosol generating article 2, and other heaters 130 may be arranged outside the aerosol generating article 2. In addition, the shape of the heater 130 is not limited to Figures 1 to 3 The shapes shown in , and may include various shapes.

[0074] The vaporizer 14 may be a component that stores an aerosol-generating substance and generates vaporized aerosol by heating the aerosol-generating substance.

[0075] The vaporizer 14 may include a liquid storage portion, a liquid delivery element, and a heating element, but is not limited thereto. For example, the liquid storage portion, the liquid delivery element, and the heating element may be included in the aerosol generating device 1 as separate modules.

[0076] The liquid storage portion can store an aerosol-generating substance. For example, the aerosol-generating substance can be a liquid containing a tobacco-containing substance having a volatile tobacco aroma component, or can be a liquid containing a non-tobacco substance. The liquid storage portion can be formed to be detachable from / attached to the vaporizer 14, or can be formed integrally with the vaporizer 14.

[0077] For example, the aerosol generating substance may include: water, solvents, ethanol, plant extracts, spices, flavoring agents or vitamin mixtures. Spices may include menthol, peppermint, spearmint oil and various fruity ingredients, but are not limited thereto. Flavoring agents may include ingredients that can provide various fragrances or tastes to the user. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C and vitamin E, but is not limited thereto. In addition, the aerosol generating substance may include aerosol forming substances such as glycerol and propylene glycol.

[0078] The liquid transport element can transport the aerosol-generating substance in the liquid storage portion to the heating element. For example, the liquid transport element can be a core such as cotton fiber, ceramic fiber, glass fiber or porous ceramic, but is not limited thereto.

[0079] The heating element may be an element for heating the aerosol generating substance conveyed by the liquid conveying element. For example, the heating element may be a metal heating wire, a metal hot plate, a ceramic heater, etc., but is not limited thereto. In addition, the heating element may include a conductive wire such as a nickel-chromium alloy wire, and may be positioned to be wound around the liquid conveying element. The heating element may be heated by a supply of electric current, and may heat the aerosol generating substance by transferring heat to the aerosol generating substance in contact with the heating element. As a result, an aerosol may be generated from the aerosol generating substance.

[0080] The generated aerosol can move along the air flow path. Figure 1 and Figure 2 As shown, the aerosol moving along the air flow path can be delivered to the user by passing through the aerosol generating article 2. Figure 3 As shown, the aerosol moving along the air flow path can be delivered to the user through the mouthpiece 18.

[0081] The vaporizer 14 may be referred to as a cartomizer or an atomizer, but is not limited thereto.

[0082] According to an embodiment, the vaporizer 14 may be a cartridge that can be inserted into and separated from the body of the aerosol generating device 1 or the aerosol generating device 1. When the stored aerosol generating substance is completely consumed, the vaporizer 14 may be replenished with the aerosol generating substance or may be replaced with another vaporizer 14 storing the aerosol generating substance.

[0083] Hereinafter, a component corresponding to the vaporizer 14 may be referred to as a cartridge, and a cartridge and an aerosol generating device including the same according to an embodiment will be described in detail below.

[0084] Figure 4A to Figure 5 2 is a view showing a cartridge and an aerosol generating device including the cartridge according to an embodiment.

[0085] FIG. 4A is a perspective view schematically showing an aerosol generating device according to an embodiment.

[0086] FIG. 4B is a perspective view showing the aerosol generating device shown in FIG. 4A with the cartridge separated from the main body.

[0087] Figure 5 It is a cross-sectional view taken along the VV direction of the aerosol generating device shown in FIG. 4A .

[0088] 4A to Figure 5 The aerosol generating device 1 according to the embodiment may include a main body 10 and a cigarette cartridge 20 .

[0089] At least one of the components of the aerosol generating device 1 according to the embodiment may be connected to Figures 1 to 3 At least one of the components of the aerosol generating device 1 shown in FIG. 1 is the same or similar, and the same description is omitted below.

[0090] The body 10 may form a part of the appearance of the aerosol generating device 1 and may perform the function of accommodating and protecting components of the aerosol generating device 1. For example, the battery 11 and the controller 12 may be accommodated inside the body 10, but is not limited thereto.

[0091] The body 10 may be manufactured in various shapes, such as a cylindrical shape, an elliptical cylindrical shape, or a rectangular parallelepiped shape, but is not limited to this embodiment.

[0092] The cartridge 20 may be detachably coupled to one end of the body 10 to form the appearance of the aerosol generating device 1 together with the body 10. The cartridge 20 may be coupled to the body 10 to be applied as a component of the aerosol generating device 1. A mouthpiece 240 may be arranged in an upper portion of the cartridge 20, through which the aerosol may be inhaled.

[0093] The cartridge 20 may be coupled to the main body 10 while accommodating the aerosol generating substance. For example, the cartridge 20 may be mounted on the main body 10 when a portion of the cartridge 20 is inserted into the main body 10, or a portion of the main body 10 is inserted into the cartridge 20. Here, the main body 10 and the cartridge 20 may be coupled to each other by a snap-fit ​​method, a screw coupling method, a magnetic coupling method, an interference fitting method, etc. However, the coupling method between the main body 10 and the cartridge 20 is not limited to the above description.

[0094] 4B, the cartridge 20 may be aligned with the main body 10 along the z-axis. When the positions of the cartridge 20 and the main body 10 are aligned with each other, the cartridge 20 may be coupled to the main body 10 by approaching in the -z direction. The cartridge 20 may be separated from the main body 10 in the +z direction. When the cartridge 20 is separated from the main body 10, components of the main body 10 may be exposed to the outside.

[0095] Generally speaking, the cigarette cartridge includes a heating element that is electrically operated to atomize the aerosol-generating substance. Here, the heating element may be included in the above reference Figures 1 to 3 A heating element in the carburetor 14 is described.

[0096] When the cigarette cartridge is connected to the main body, the heating element can be electrically connected to the main body to receive power from the battery through the contact terminal, and the power supplied to the heating element can be controlled by the controller. In other words, when power is supplied to the heating element, the power supplied to the heating element is controlled, and the heating element can be directly electrically heated.

[0097] In a method of directly electrically heating a heating element through a contact terminal (hereinafter referred to as a wired heating method), heat loss inevitably occurs at the contact terminal and the power supply line.

[0098] In addition, in the wired heating method, all parts of the heating element can be uniformly heated. A part of the heating element may have a temperature higher than the target temperature, while another part of the heating element may have a temperature lower than the target temperature. Here, the part having a temperature higher than the target temperature may carbonize the core.

[0099] Carbonization may refer to blackening due to high temperature heating. Harmful substances may be generated during the carbonization of the core, and the harmful substances may be mixed with the aerosol and introduced into the user's mouth.

[0100] The aerosol generating device 1 according to the embodiment can generate aerosol by heating the heating element by induction heating method to solve the heat loss and hazard problems described above. The induction heating method may refer to a wireless heating method in which a heating body including only a susceptor generates heat in response to an induced magnetic field.

[0101] The induction heating method can be a wireless heating method, and thus, heat loss can be reduced compared to heat loss of a wired heating method. Therefore, heating efficiency can be improved, and thus power consumption can be reduced.

[0102] In addition, contact terminals and power supply lines are not required, and therefore, the induction heating method can reduce heat generated by the aerosol generating device compared to the wired heating method.

[0103] In addition, the induction heating method can prevent the change of contact resistance caused by the frequent attachment and detachment of the cigarette cartridge and the main body. In addition, the freedom of the appearance design of the cigarette cartridge is improved through the simple structure of the cigarette cartridge.

[0104] The induction heating method can heat the susceptor relatively uniformly, and therefore, the temperature of the susceptor can be relatively uniform in all parts of the susceptor compared to the wire heating method. In other words, the induction heating method can prevent some parts of the susceptor from being heated above the target temperature, and thus can reduce the generation of harmful substances due to carbonization of the core.

[0105] The aerosol generating device 1 applying the induction heating method may include an induction coil 110 for generating an induction magnetic field and a susceptor 230 heated by the induction magnetic field.

[0106] The arrangement of the induction coil and the susceptor can significantly affect the atomization of the aerosol-generating material stored inside the cartridge in the induction heating method. According to an embodiment, both the induction coil and the susceptor can be arranged in the cartridge as a component of the cartridge. As another example, the induction coil can be arranged in the body as a component of the body, and the susceptor can be arranged in the cartridge as a component of the cartridge.

[0107] In the following description, it is assumed that the induction coil 110 is a component of the main body 10 disposed in the main body 10 , and the susceptor 230 is a component of the cartridge 20 disposed in the cartridge 20 .

[0108] The body 10 may include an induction coil 110 for generating an induction magnetic field. The induction coil 110 may be disposed below the cartridge 20 and may generate an induction magnetic field toward a susceptor 230 disposed inside the cartridge 20.

[0109] The induction coil 110 may be supplied with power from the battery 11. When power is supplied to the induction coil 110, a magnetic field may be formed toward a lower portion of the cartridge 20.

[0110] When an alternating current is applied to the induction coil 110, the direction of the magnetic field formed toward the lower portion of the cartridge 20 may be periodically changed. When the susceptor 230 is exposed to the magnetic field formed by the induction coil 110, the susceptor 230 may generate heat. When the susceptor 230 generates heat, the aerosol generating substance may be heated.

[0111] When the amplitude or frequency of the magnetic field formed by the induction coil 110 changes, the temperature of the susceptor 230 may change. The controller 12 may adjust the amplitude or frequency of the alternating magnetic field formed by the induction coil 110 by controlling the power supplied to the induction coil 110, and thus may control the temperature of the susceptor 230.

[0112] The induction coil 110 may include copper, but is not limited thereto. The induction coil 110 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 silver (Ag), gold (Au), aluminum (Al), tungsten (W), zinc (Zn), and nickel (Ni), so that the induction coil 110 allows a higher current to flow through the induction coil 110 by having a lower specific resistance.

[0113] The induction coil 110 may include a spiral plate shape arranged to intersect the longitudinal direction of the body 10. Here, the longitudinal direction of the body 10 may refer to the z-axis direction, which is the length direction of the cigarette cartridge 20. Figure 8 The spiral plate shape of the induction coil 110 and the direction of the magnetic lines of force are described.

[0114] Regarding the resonance phenomenon and efficiency of induction heating, the efficiency of induction heating may increase when the frequency of the power supplied to the induction coil 110 becomes closer to the resonance frequency of the susceptor 230. The resonance frequency of the susceptor 230 may be determined by various factors. When a plurality of susceptors 230 are arranged, the resonance frequencies of the susceptors 230 may be different from each other.

[0115] When one induction coil 110 is arranged, a plurality of susceptors 230 inductively heated by the one induction coil 110 may have different heating efficiencies. Therefore, one or more induction coils 110 may be arranged according to the number of susceptors 230 to ensure a high heating efficiency of the susceptors 230. In this case, power may be supplied to each induction coil 110 individually so that each induction coil 110 may have a frequency close to the resonant frequency of the corresponding susceptor 230.

[0116] The body 10 may include an air inlet 120 in at least one area of ​​a side surface of the body 10. Air from outside the aerosol generating device 1 may be introduced into the body 10 through the air inlet 120, and the introduced air may pass through the interior of the aerosol generating device 1 and mix with the aerosol inside the cartridge 20. The aerosol may then pass through the interior of the cartridge 20 and be provided to the user through the mouthpiece 240.

[0117] The cartridge 20 according to the embodiment may include a housing 200 , a storage unit 210 , a core 220 , a susceptor 230 , a mouthpiece 240 , and an air flow path 250 .

[0118] Here, the storage unit 210 and the core 220 may be respectively Figures 1 to 3 The liquid storage portion and liquid delivery element included in the vaporizer 14 described above are the same. The mouthpiece 240 can be the same as Figures 1 to 3 The cigarette holder 18 is the same.

[0119] The housing 200 may form the appearance of the cartridge 20, and may perform the function of accommodating and protecting the components of the cartridge 20. The storage unit 210, the core 220, the susceptor 230, etc. may be accommodated in the housing 200, but the present disclosure is not limited thereto.

[0120] The housing 200 may have a shape corresponding to the shape of the body 10. For example, when the body 10 has a cylindrical shape, at least a portion of the housing 200 may have a cylindrical shape corresponding to the shape of the body 10. However, the shapes of the body 10 and the housing 200 are not limited to this embodiment.

[0121] The housing 200 may include a structure that can be detachably coupled to one end of the body 10 and a structure for maintaining a coupled state between the body 10 and the cartridge 20 .

[0122] The storage unit 210 may store a liquid aerosol-generating substance or a gel aerosol-generating substance.

[0123] The storage unit 210 may be manufactured in various shapes, such as a cylindrical shape, an elliptical cylindrical shape, or a rectangular parallelepiped shape. According to an embodiment, the storage unit 210 may have a tubular shape including a hollow portion surrounded by an inner wall and having an outer wall, at least a portion of which narrows toward the upper portion of the storage unit 210. The aerosol generating substance may be stored in the empty space surrounded by the outer wall and the inner wall of the storage unit 210.

[0124] The storage unit 210 may include at least one opening (not shown) through which the storage unit 210 is connected to the core 220. The opening may be arranged in a lower portion of the storage unit 210. According to an embodiment, the core 220 may be arranged at the opening and may contact the aerosol generating substance flowing out of the storage unit 210 through the opening.

[0125] However, the arrangement relationship between the opening and the core 220 is not limited to this embodiment. As another example, the core 220 may be inserted into the storage unit 210 through the opening and contact the aerosol generating substance stored inside the storage unit 210.

[0126] The gap between the opening of the storage unit 210 and the core 220 may be sealed and prevent the aerosol generating substance from leaking. In other words, the storage unit 210 may be sealed to prevent the aerosol generating substance from leaking to the outside of the storage unit 210 in addition to leaking through the core 220.

[0127] The core 220 may be disposed below the storage unit 210 and may absorb the aerosol generating substance by receiving the aerosol generating substance supplied from the storage unit 210 .

[0128] The core 220 may have various shapes. As an example, the core 220 may have an elongated shape. As another example, the core 220 may have a cylindrical shape extending in one direction. In detail, the core 220 may have a polygonal column shape, such as a cylindrical shape, a rectangular column shape, or a triangular column shape, but is not limited to the examples mentioned above, and the core 220 may have a shape that is approximately a rod or a needle.

[0129] At least a portion of the core 220 may absorb the aerosol generating substance supplied from the storage unit 210. For example, the aerosol generating substance absorbed into a portion of the core 220 may move to another portion of the core 220 according to capillary action.

[0130] According to an embodiment, the core 220 may absorb the aerosol generating substance supplied from the storage unit 210 through one end portion (e.g., the upper end portion) of the core 220, and the absorbed aerosol generating substance may move to the other end portion (e.g., the lower end portion) of the core 220.

[0131] The core 220 may include porous ceramics. However, the material of the core 220 is not limited to this embodiment, and the material of the core 220 may include all types of porous materials for transmitting an aerosol generating substance.

[0132] The susceptor 230 may atomize the aerosol generating substance heated by the induced magnetic field and absorbed into the core 220 into an aerosol.

[0133] The susceptor 230 may include ferrite-based stainless steel. However, the material of the susceptor 230 is not limited to this embodiment, and the material of the susceptor 230 may include all types of metal bodies having magnetism capable of induction heating.

[0134] The susceptor 230 may be disposed adjacent to the core 220. According to an embodiment, the susceptor 230 may be disposed on a lower portion of the core 220. Here, the susceptor 230 may contact a lower surface of the core 220 and heat the aerosol generating substance absorbed into the core 220.

[0135] The susceptor 230 may be coupled to the core 220. Here, coupling may refer to all methods of permanently or reversibly attaching the susceptor 230 to the core 220 when the core 220 has been manufactured, such as applying, spraying, depositing, plating, dipping, painting, printing, 3D printing, and using equipment, and all methods such as sintering the susceptor 230 with the core during the manufacturing process of the core 220. Hereinafter, when the susceptor 230 is "arranged" on the core 220, it may refer to the case where the susceptor 230 is coupled to the core 220, is simply in contact with the core 220, or is not in contact with the core 220.

[0136] When the body 10 and the cartridge 20 are coupled to each other, the susceptor 230 may be disposed above the induction coil 110. Here, the susceptor 230 may be physically separated from the induction coil 110 by the housing 200.

[0137] Reference Figure 5, a distance d1 from the lower portion of the storage unit 210 to the susceptor 230 may be smaller than a distance d2 from the lower portion of the storage unit 210 to the induction coil 110. In other words, the susceptor 230 may be spaced apart from the induction coil 110 by a distance obtained by subtracting the distance d1 from the distance d2.

[0138] The mouthpiece 240 may be arranged in the upper portion of the cartridge 20 and may contact the user's mouth. The mouthpiece 240 may be formed to protrude from the cartridge 20 in the +z direction. The mouthpiece 240 may have a shape that may easily contact the user's mouth. The user may inhale the aerosol after contacting the mouthpiece 240 formed in the cartridge 20 with the mouth.

[0139] The air flow path 250 may operate as a channel through which the atomized aerosol is delivered to the user. That is, the air flow path 250 may refer to a moving path inside the cartridge 20 through which the aerosol atomized by the receptor 230 of the cartridge 20 moves to the mouthpiece 240.

[0140] External air may flow into the body 10 through the air inlet 120, move along an air inflow path (not shown) formed in the body 10 to reach the interior of the cartridge 20, and mix with the aerosol. The aerosol mixed with the air may move along the air flow path 250 and may be provided to the user through the mouthpiece 240.

[0141] A portion of the air flow path 250 may be disposed adjacent to the core 220 and the susceptor 230, and another portion of the air flow path 250 may be disposed adjacent to the mouthpiece 240. In other words, the air flow path 250 may fluidly connect the mouthpiece 240 to the space where the core 220 and the susceptor 230 are disposed.

[0142] According to an embodiment, the air flow path 250 may be formed along a tube extending from the core 220 and the susceptor 230 to the mouthpiece 240 surrounded by the inner wall of the storage unit 210. However, the arrangement structure of the air flow path 250 is not limited to this embodiment. As another example, the air flow path may be formed along the outside of the storage unit.

[0143] 6A and 6B are perspective views schematically showing various embodiments of the cigarette cartridge.

[0144] At least one of the components of the cartridge 20 shown in FIG. 6A and the cartridge 20 shown in FIG. 6B may be the same as or similar to at least one of the components of the cartridge 20 shown in FIGS. 4A to 4B , and the same description is omitted.

[0145] According to an embodiment, referring to FIG. 6A , the cartridge 20 shown in FIG. 6A may be the same as the cartridge 20 shown in FIG. 4A .

[0146] 6B , the cartridge 20a shown in FIG. 6B is different from the cartridge 20 shown in FIG. 6A in that the housing 200 is not provided. The cartridge 20a may include a storage unit 210a, a core 220, a susceptor 230, a mouthpiece 240, and an air flow path 250.

[0147] The cartridge 20 a may not include the housing 200 , and the outer wall of the storage unit 210 a may partially perform the function of the housing 200 .

[0148] As shown in Fig. 6B, the core 220 may protrude from the lower portion of the storage unit 210a. Therefore, the core 220 and the susceptor 230 may be exposed to the outside of the cartridge 20a.

[0149] When the body 10 and the cartridge 20a are coupled to each other, the induction coil 110 and the susceptor 230 may be arranged in one space, rather than in physically separated spaces. However, even in this case, the susceptor 230 may be spaced apart from the induction coil 110 without contacting the induction coil 110.

[0150] Figure 7A to Figure 8 is a view showing the direction of magnetic lines of force and an induction coil having a spiral plate shape.

[0151] 7A to 7C are views illustrating various shapes of an induction coil of an aerosol generating device according to an embodiment. Figure 8 is a view showing the directions of magnetic lines of force generated by an induction coil of an aerosol generating device according to an embodiment.

[0152] 7A to 7C , an aerosol generating device according to an embodiment (eg, the aerosol generating device 1 of FIG. 4A ) may include induction coils 110 a , 110 b , and 110 c having various shapes.

[0153] The induction coil 110 disposed inside the body 10 can be implemented in various shapes, such as a spiral, rectangular or pancake-shaped toroidal coil. The number of turns and shape of the induction coil 110 can be changed according to the induction heating resonant frequency and the external design of the cartridge and the body.

[0154] The induction coils 110a, 110b, and 110c shown in FIGS. 7A to 7C may generally have a spiral plate shape. Figure 8 The induction coil 110 having a spiral plate shape can form a magnetic field in which magnetic lines of force M enter and leave around the spiral axis of the induction coil 110 according to the direction of the current.

[0155] The susceptor 230 may be arranged in the same direction as the induction coil 110 having the spiral plate shape. Here, the same direction may mean that the susceptor 230 is arranged in parallel with the induction coil 110 having the spiral plate shape.

[0156] As an example, the induction coil 110 and the susceptor 230 may be arranged in the same direction in a manner intersecting the longitudinal direction of the body (e.g., the body 10 of FIG. 4A ). In detail, the induction coil 110 and the susceptor 230 may be arranged in a manner parallel to the direction along which the lower surface of the storage unit (e.g., the storage unit 210 of FIG. 4A ) extends. However, the embodiment is not limited to the arrangement structure of the induction coil and the susceptor. As another example, the induction coil and the susceptor may be arranged in a direction parallel to the longitudinal direction of the body.

[0157] According to an embodiment, the magnetic lines M may enter and leave the core 220 and the susceptor 230 arranged in parallel with the lower surface of the storage unit in the longitudinal direction of the body 10. In other words, the magnetic lines M may pass through the core 220 and the susceptor 230 arranged parallel to the xy plane in the z-axis direction.

[0158] Here, the susceptor 230 may be arranged such that the central portion of the susceptor 230 is located at a position corresponding to the central portion of the spiral axis of the induction coil 110 along the longitudinal direction of the body. For example, the central portion of the susceptor 230 may be aligned with the central portion of the spiral axis of the induction coil 110 in the z-axis direction. Therefore, the density of magnetic field lines M entering and leaving the susceptor 230 may be increased.

[0159] According to an embodiment, unlike the induction coil included in the existing induction heating aerosol generating device, the direction of the magnetic lines of force M can be a direction that intersects (e.g., is perpendicular to) the direction along which the susceptor 230 extends, and thus the density of the magnetic lines of force M passing through the susceptor 230 can be increased, and the heating efficiency of the susceptor 230 can be improved accordingly.

[0160] In particular, when the susceptor 230 has a flat sheet shape, the magnetic lines of force M may pass through a larger area of ​​the sheet shape, and thus the susceptor 230 may be sufficiently heated.

[0161] Fig. 9 is a perspective view showing a core and a susceptor arranged in a cartridge according to an embodiment.

[0162] Reference Fig. 9 According to an embodiment, the cartridge 20 may include a core 220 and one or more susceptors 230 .

[0163] Fig. 9At least one of the components of the illustrated cartridge 20 may be the same as or similar to at least one of the components of the cartridge 20 illustrated in FIG. 4A , and thus the same description of the component is omitted.

[0164] Unlike the core 220 having a cylindrical shape shown in FIG. 4A , Fig. 9 The core 220 shown may have a rectangular parallelepiped shape. However, the embodiment is not limited to the shape of the core.

[0165] According to an embodiment, one or more susceptors 230 may be arranged on the core 220. In the existing wired heating method, both ends of the heating element need to be connected to the contact terminals. Therefore, when multiple heating elements are arranged on multiple surfaces of the core, the number of contact terminals corresponding to the number of heating elements may be required. Therefore, the internal structure of the cartridge may be complicated, and therefore, it may not be easy to implement multiple heating elements in the limited space inside the cartridge.

[0166] According to the induction heating of the wireless heating method, the contact terminal and the power supply line for the susceptor 230 are not required. Therefore, the arrangement structure of the susceptor 230 is not greatly affected by the space limitation inside the cartridge 20. In other words, a plurality of susceptors 230 can be arranged on the core 220. According to the induction heating method, the degree of freedom of the arrangement structure of the susceptor 230 relative to the core 220 can be improved, and the internal structure of the cartridge 20 can be simplified.

[0167] One or more susceptors 230 may be arranged on the inner and / or outer surface of the core 220. As an example, the susceptor 230 may be inserted into a groove (not shown) formed in the first outer surface of the core 220. Here, the susceptor 230 inserted into the groove may be coplanar with the remaining portion of the first outer surface of the core 220 where the groove is not formed. Therefore, the first outer surface of the core may be flat and smooth in the entire area without a protruding portion.

[0168] When the susceptor 230 is arranged inside the core 220, aerosol may be generated inside the core 220, and thus the aerosol needs to pass through the inside of the core 220 and flow out of the core 220. In this regard, it is more effective in terms of generation and movement of aerosol when the susceptor 230 is arranged on the outer surface of the core 220. Hereinafter, an example in which the susceptor 230 is arranged on the outer surface of the core 220 is mainly described below.

[0169] The core 220 may include multiple outer surfaces. Fig. 9 There are shown the front surface, the top surface, and the side surface from among the outer surfaces of the core 220. The susceptors 230 may be arranged on a plurality of outer surfaces of the core 220, respectively.

[0170] Reference Fig. 9 , the susceptor 230u having a rectangular plate shape may be arranged on the top surface (e.g., the outer surface facing the z-axis direction) of the core 220. The susceptor 230f having a zigzag pattern portion may be arranged on the front surface (e.g., the outer surface facing the x-axis direction) of the core 220. The susceptor 230s having a straight line pattern portion may be arranged on the side surface (e.g., the outer surface facing the y-axis direction) of the core 220. However, the embodiment is not limited to the above-mentioned pattern portion and shape of the susceptor 230, and the susceptor 230 may have various pattern portions and shapes corresponding to the shape of the induction coil.

[0171] A plurality of susceptors 230 may be arranged on the outer surface of the core 220. In other words, the plurality of susceptors 230 may be respectively arranged on a plurality of outer surfaces of the core 220, or the plurality of susceptors 230 may be arranged on the same outer surface of the core 220. As an example, a plurality of susceptors 230s having a straight line pattern portion may be arranged in parallel on the side surface of the core 220.

[0172] According to an embodiment, one or more susceptors 230 may be arranged on at least one outer surface of the core 220, and thus, the contact area and heating area of ​​the susceptor 230 relative to the core 220 may be increased. Therefore, the heating efficiency may be improved and the atomization performance may be improved eventually.

[0173] Hereinafter, various pattern parts of a susceptor for improving atomization performance are described below with reference to FIGS. 10A to 10C .

[0174] 10A to 10C are top views of a core on which a susceptor having evenly spaced pattern portions is arranged according to an embodiment.

[0175] 10A to 10C, the cartridge 20 according to various embodiments may include a core 220 and susceptors 230a, 230b, and 230c. The susceptors 230a, 230b, and 230c may be the same or similar to the susceptor 230 shown in FIG. 4A, and the same description of the susceptor is described based on the susceptor 230 shown in FIG. 4A.

[0176] The aerosol-generating substance absorbed by the core 220 may be heated and atomized into an aerosol by the susceptor 230. The generated aerosol may flow out of the core 220 and move to an air flow path (eg, the air flow path 250 of FIG. 4A).

[0177] The generated aerosol may not pass through the susceptor 230. Therefore, the aerosol may bypass the susceptor 230 and pass through a portion of the core 220 where the susceptor 230 is not arranged.

[0178] When the susceptor 230 is arranged on the outer surface of the core 220, the outer surface of the core 220 may be divided into a first area where the susceptor 230 is arranged and a second area where the susceptor 230 is not arranged. In other words, the second area may correspond to the remaining area on the outer surface of the core 220 after excluding the first area.

[0179] Hereinafter, a portion or the entirety of the second region of the core 220 , in which the susceptor 230 is not arranged and thus the aerosol can flow out of the core 220 , may be referred to as a discharge region.

[0180] The aerosol may move from the core 220 to the outside of the core 220 through the discharge area 225. In particular, the aerosol blocked by the susceptor 230 may flow out of the core 220 through the discharge area 225 around the susceptor 230 while moving inside the core 220. Therefore, the discharge area 225 may refer to an area adjacent to and formed along the edge of the susceptor 230.

[0181] Preferably, the edge of the susceptor 230 disposed on the core 220 may be longer to ensure a larger discharge area 225 .

[0182] For example, when a susceptor having a rectangular plate shape (e.g. Fig. 9 When the susceptor 230u of the core 220 is arranged on the core 220, the aerosol does not flow out of the first area of ​​the core 220 where the susceptor is arranged, and therefore, the aerosol inside the core 220 may be blocked by the susceptor in a relatively large area. In particular, the aerosol atomized on the central portion of the core 220 needs to move a long distance to reach the discharge area 225 formed on the edge of the susceptor 230u and the peripheral portion of the core 220 to flow out of the core 220.

[0183] In contrast, when a plurality of susceptors having a zigzag pattern portion (e.g. Fig. 9 susceptor 230f) or a plurality of susceptors having a straight line pattern portion (e.g., Fig. 9 When the susceptor 230s is arranged on the core 220, the second area can be formed between the first areas. Therefore, the discharge area 225 can be formed in a relatively large area, and the aerosol can flow out of the core 220 smoothly.

[0184] Therefore, with the same total area of ​​the susceptor 230, when the edge of the susceptor 230 is designed to be longer, the discharge area 225 can be formed to a large extent.

[0185] 10A to 10C respectively illustrate susceptors 230a, 230b, and 230c having various pattern portions with longer edges. When susceptors 230a, 230b, and 230c having various pattern portions are arranged on the outer surface of the core 220, two pattern portions of the susceptor 230 may be arranged in at least one area of ​​the outer surface of the core 220.

[0186] Here, "two pattern parts" may refer to two separate susceptors that are not directly / physically connected to each other and are separated from each other in the entire area of ​​the outer surface of the core, and may refer to two different parts of the same susceptor extending in parallel on the outer surface of the core. In other words, according to the method of setting one area of ​​the outer surface of the core, one pattern part of the susceptor may be expressed as a plurality of pattern parts in the one area.

[0187] Here, the drain region 225 may refer to a space formed between two pattern parts of the susceptor 230. That is, the drain region 225 may be formed between different parts of the same susceptor or between two separate susceptors arranged on the same outer surface of the core 220.

[0188] As the edge of the susceptor 230 increases, the discharge area 225 may increase. As a result, the amount of aerosol flowing out of the core 220 through the enlarged discharge area 225 may increase. Therefore, the atomization performance may be improved.

[0189] 10A to 10C show that the aerosol moves from the edge of the susceptor 230 in the x-axis direction and the y-axis direction to flow out of the core 220 because the aerosol cannot pass through the susceptor 230 .

[0190] However, the movement direction of the generated aerosol is not limited to the direction shown in the figure. It is easy for a person skilled in the art to understand that the aerosol can also move along the z-axis direction and flow out of the core 220 through the discharge area 225. In addition, it is easy for a person skilled in the art to understand that the movement of the aerosol generated by the susceptor 230 is only shown in a part of the figure.

[0191] 10A , the susceptor 230a may have a spiral pattern portion. Although FIG. 10A shows the susceptor 230a having a rectangular spiral pattern portion, the spiral pattern portion is not limited to the embodiment shown in FIG. 10A .

[0192] In order to facilitate the manufacturing process of the susceptor and reliable atomization performance between adjacent pattern parts, the distance id between the two pattern parts of the susceptor 230a can be uniform. Here, the distance between the two pattern parts can refer to the distance between the two adjacent edges (i.e., two adjacent parts) of one or more susceptors when they extend in parallel. This distance can be used in the same meaning below. In addition, hereinafter, the distance of the susceptor can be used in the same meaning as the distance between the two pattern parts.

[0193] 10B , the susceptor 230 b may include a plurality of first pattern sections 231 sequentially arranged in one direction (eg, in the y-axis direction) and a plurality of second pattern sections 232 connecting the plurality of first pattern sections 231 in one direction.

[0194] Here, the connection may include direct connection in the form of a pattern portion of a susceptor and indirect connection such as heat conduction through an electromagnetic field. For direct connection, the second pattern portion 232 may include various pattern portions connecting the first pattern portion in one direction, such as a bent or curved pattern portion and a straight pattern portion as shown in FIG. 10B.

[0195] The first pattern portion 231 may include one or more first extension pattern portions 231 extending in a direction intersecting the above-mentioned one direction (e.g., the x-axis direction), one or more second extension pattern portions 2312 extending in one direction (e.g., the y-axis direction), and a connection pattern portion 2313 connecting the first extension pattern portion 231 and the second extension pattern portion 2312. The one or more connection pattern portions 2313 may be arranged according to the number of the first extension pattern portions 2311 and the second extension pattern portions 2312, and may include various pattern portions such as bent or curved pattern portions.

[0196] The distance id between the two pattern portions of the susceptor 230b may be uniform.

[0197] 10B , the distance id between two first extension pattern portions 2311 included in the same first pattern portion 231 may be uniform in the direction (e.g., the x-axis direction) along which the two first extension pattern portions 2311 extend. In addition, the distance between two adjacent first extension pattern portions 231 of different first pattern portions 231 may be the same as the distance id described above.

[0198] 10C, the susceptor 230c may have a pattern portion similar to that of the susceptor 230b shown in FIG10B, and the pattern portion of the susceptor 230c is sequentially arranged along one direction (e.g., the y-axis direction). The susceptor 230c may include a plurality of first pattern portions 231c sequentially arranged along the one direction (e.g., the y-axis direction) and a plurality of second pattern portions 232c connecting the plurality of first pattern portions 231c along the one direction (e.g., the y-axis direction).

[0199] Unlike the straight line pattern portion shown in Fig. 10B, the second pattern portion 232c shown in Fig. 10C is shown as a curved pattern portion. However, the second pattern portion 232c is not limited to this embodiment and may include various pattern portions.

[0200] The first pattern portion 231 c shown in FIG. 10C may include two or more first extension pattern portions 2311 extending in a direction (eg, x-axis direction) intersecting the one direction described above, and a connection pattern portion 2313 c connecting the two first extension pattern portions 2311 .

[0201] 10B, the connection pattern portion 2313c shown in FIG10C is shown as a bent pattern portion. However, the connection pattern portion 2313c is not limited to this embodiment and may include various pattern portions.

[0202] In the bent pattern portion, heat may be concentrated on the bent portion. When the second pattern portion 232c and the connecting pattern portion 2313c are arranged in a bent pattern portion, the concentration of heat on a portion of the pattern portion can be alleviated and the heat can be uniformly distributed in the entire area of ​​the pattern portion.

[0203] Similar to the susceptor 230b shown in FIG10B , the distance id between the two pattern portions of the susceptor 230c may be uniform and may be the same throughout the susceptor 230c.

[0204] 10A to 10C, the first region (i.e., the region occupied by the susceptor 230 in one of the outer surfaces of the core 220) may be formed at a position spaced the same distance from the edge of one of the outer surfaces of the core 220, and may occupy 80% or less of the one surface. For example, the first region may occupy 70% to 80% of one of the outer surfaces of the core 220.

[0205] By arranging the receptor 230 so that the first region occupies 70% to 80% of one of the outer surfaces of the core 220 at a position spaced the same distance from the edge of the one surface, sufficient space can be secured for the aerosol generating material to move from the storage unit (e.g., the storage unit 210 of Figure 4A) to the core 220.

[0206] In other words, the core 220 can effectively absorb the aerosol generating substance supplied from the storage unit. Therefore, the leakage of the aerosol generating substance from the storage unit can be reduced.

[0207] Hereinafter, an example in which the distance between two pattern parts of a susceptor is uneven is described below with reference to FIGS. 11A and 11B .

[0208] 11A and 11B are top views of a core arranged with a susceptor having unevenly spaced pattern portions according to an embodiment.

[0209] 11A and 11B, the cartridge 20 may include a core 220 and susceptors 230a and 230b. The susceptors 230a and 230b may be the same or similar to the susceptor 230 shown in FIG. 4A, and the same description of the susceptors 230a and 230b is given based on the susceptor 230 shown in FIG. 4A.

[0210] Unlike the susceptors 230a and 230b shown in FIGS. 10A and 10B , the distance between two pattern portions of the susceptors 230a and 230b shown in FIGS. 11A and 11B (eg, id of FIGS. 10A and 10B ) may vary depending on the position of the susceptor 230 .

[0211] 11A and 11B , the susceptors 230a and 230b may include a first portion 2301 disposed on the peripheral portion 220p of the core 220 at a first distance id1 (ie, a distance d1 between two adjacent pattern portions), and a second portion 2302 disposed on the central portion 220c of the core 220 at a second distance id2.

[0212] Here, each of the first distance id1 and the second distance id2 may be used in the same meaning as the distance id between two pattern portions of the susceptor described in FIGS. 10A to 10C .

[0213] The first distance id1 and the second distance id2 may be different from each other. For example, the first distance id1 with respect to the peripheral portion 220 p of the core 220 may be greater than the second distance id2 with respect to the central portion 220 c of the core 220 .

[0214] The difference between the first distance id1 and the second distance id2 can be described in three aspects - the characteristics of the induction heating method, the components of the body arranged around the core, and the absorptivity of each portion of the core.

[0215] First, due to the nature of the induction heating method, magnetic field lines (e.g. Figure 8 The magnetic flux density of the magnetic field lines M) can be obtained in an induction coil having a spiral plate shape (for example, Figure 8 That is, the magnetic flux density at the central portion 220c of the core 220 close to the central axis of the induction coil may be relatively higher than the magnetic flux density at the peripheral portion 220p of the core 220.

[0216] Therefore, when the second portion 2302 of the susceptors arranged on the central portion 220c is arranged more densely than the first portion 2301 of the susceptors arranged on the peripheral portion 220p, the heating efficiency of the induction heating method may be maximized.

[0217] Secondly, one or more parts of the body (e.g., the body 10 of FIG. 4A ) such as a support element for supporting the core 220 may be arranged around an edge or both ends of the core 220 corresponding to the peripheral portion 220p of the core 220. When heat is transferred to the body due to the increase in temperature of the peripheral portion 220p of the core 220, the body may be damaged. For example, parts of the body may be thermally deformed.

[0218] When the first portion 2301 of the susceptors arranged on the peripheral portion 220p is less dense than the second portion 2302 of the susceptors arranged on the central portion 220c, the temperature of the peripheral portion 220p may be lower than that of the central portion 220c of the core 220.

[0219] Therefore, heat transferred from the peripheral portion 220p to the main body is reduced, and thus the main body can be protected from heat generated by the susceptor 230a and the susceptor 230b.

[0220] Finally, the edge or both ends of the core 220 corresponding to the peripheral portion 220p may absorb the aerosol generating substance supplied from the storage unit (eg, the storage unit 210 of FIG. 4A ). The absorbed aerosol generating substance may move from the peripheral portion 220p of the core 220 to the central portion 220c.

[0221] The peripheral portion 220p of the core 220 may be directly supplied with the aerosol generating substance from the storage unit, and therefore, the absorption rate of the aerosol generating substance may be high at the peripheral portion 220p of the core 220. The central portion 220c is relatively far from the storage unit, and therefore, the absorption rate of the aerosol generating substance may be relatively low at the central portion 220c of the core 220. In other words, the absorption rate of the aerosol generating substance and the amount of the aerosol generating substance absorbed may decrease from the peripheral portion 220p of the core 220 toward the central portion 220c.

[0222] As described above, when the first portion 2301 of the susceptor is arranged less densely than the second portion 2302 , the temperature of the peripheral portion 220 p may be lower than the temperature of the central portion 220 c of the core 220 .

[0223] Therefore, the amount of aerosol atomized by the first portion 2301 of the susceptor can be reduced at the peripheral portion 220p of the core 220. The aerosol-generating substance that is not atomized at the peripheral portion 220p can move to the central portion 220c of the core 220 and can be atomized into an aerosol by the second portion 2302 of the susceptor at the central portion 220c. Therefore, a uniform amount of aerosol can be generated at the peripheral portion 220p and the central portion 220c of the core 220.

[0224] 11A , a boundary line between the peripheral portion 220 p and the central portion 220 c of the core 220 is shown as a rectangle having a single-dot chain line, which is a rectangle in which the upper surface of the core 220 is reduced by 4:1.

[0225] 11B , a boundary line between the peripheral portion 220 p of the core 220 and the central portion 220 is shown to divide the length of the upper surface of the core 220 (ie, the dimension in the y-axis direction) into three equal parts.

[0226] However, the peripheral portion and the central portion of the core are not limited to this embodiment, and the boundary between the peripheral portion and the central portion may be different. In addition, the boundary between the peripheral portion and the central portion of the core may not be clear, and in this case, the distance between the pattern portions of the susceptor may gradually decrease or suddenly decrease from the peripheral portion toward the central portion.

[0227] Hereinafter, a plurality of susceptors arranged on two surfaces among the outer surfaces of the core 220 will be described.

[0228] 12A and 12B are perspective views of a core with two susceptors arranged on different outer surfaces, according to an embodiment.

[0229] 12A and 12B , the cartridge 20 may include a core 220 and a plurality of susceptors 230 .

[0230] The susceptor 230 may include a first susceptor 230 - 1 disposed on one of the outer surfaces of the core 220 at a third distance id3 and a second susceptor 230 - 2 disposed on the other surface of the core facing the one surface at a fourth distance id4 .

[0231] Each of the first susceptor 230-1 and the second susceptor 230-2 may be the same as or similar to the susceptor 230 shown in FIG4A. Each of the third distance id3 and the fourth distance id4 may be used with the same meaning as the distance id between two adjacent pattern portions of the susceptor described above with reference to FIGS.

[0232] The third distance id3 and the fourth distance id4 may be different from each other. Hereinafter, it is assumed that the third distance id3 is smaller than the fourth distance id4.

[0233] 12A , the first susceptor 230 - 1 may be disposed on an upper surface of the core 220 , and the second susceptor 230 - 2 may be disposed on a lower surface of the core 220 .

[0234] A third distance id3 of the first susceptor 230 - 1 disposed on the upper surface of the core 220 may be smaller than a fourth distance id4 of the second susceptor 230 - 2 disposed on the lower surface of the core 220 , and thus more heat may be generated in the upper portion of the core 220 than in the lower portion.

[0235] The storage unit (e.g., storage unit 210 of FIG. 4A ) may be disposed at the upper portion of the core 220, but the body (e.g., body 10 of FIG. 4A ) including a plurality of electronic components may be disposed at the lower portion of the core 220. When heat generated at the lower portion of the core 220 is reduced, the electronic components of the body adjacent to the lower portion of the core 220 may be relatively protected.

[0236] Therefore, while maintaining the atomization performance by the heat generated at the upper portion of the core 220 , the electronic components arranged on the lower portion of the core 220 may be protected.

[0237] 12B , the first susceptor 230 - 1 may be disposed on a first side surface of the core 220 , and the second susceptor 230 - 2 may be disposed on a second side surface of the core 220 opposite to the first side surface.

[0238] The third distance id3 of the first susceptor 230 - 1 disposed on the first side surface may be smaller than the fourth distance id4 of the second susceptor 230 - 2 disposed on the second side surface, and thus, more heat may be generated on the first side surface than on the second side surface of the core 220 .

[0239] Reference Figure 2 , when the cartridge (e.g. Figure 2 When the vaporizer 14) is arranged asymmetrically relative to a central axis extending in the longitudinal direction of the aerosol generating device 1, the first side surface of the core 220 that generates more heat can be arranged toward the inside of the aerosol generating device 1, and the second side surface of the core 220 that generates relatively less heat can be arranged toward the outside of the aerosol generating device 1.

[0240] According to the arrangement structure of the core described above, heat transferred to the outer surface of the aerosol generating device can be reduced, and thus, high temperature heat can be prevented from being transferred to the part (eg, palm) where the user holds the aerosol generating device.

[0241] Fig.13 is a perspective view of a cartridge including a hollow portion and a joint portion according to an embodiment.

[0242] Reference Fig.13 According to an embodiment, the cartridge 20 may include a core 220 and one or more susceptors 230 .

[0243] Fig.13 At least one of the components of the cartridge 20 shown may be Fig. 9 At least one of the components of the illustrated cigarette cartridge 20 is identical or similar, and the description of the at least one identical component is omitted below.

[0244] The core 220 may include a hollow portion 220 h formed to allow the aerosol generated by the susceptor 230 to pass through the core 220 .

[0245] Reference Fig.13 , the hollow portion 220h may penetrate the core 220 in the z-axis direction. However, the size, number, and position of the hollow portion 220h may be variously modified according to the embodiment.

[0246] If the air flow path (eg, air flow path 250 of FIG. 4A ) is disposed above the core 220 and thus the aerosol needs to move in the +z direction, the aerosol generated by the susceptor 230 disposed on the lower surface of the core 220 may move through the hollow portion 220h in the +z direction.

[0247] Although not shown herein, as another example, if the air flow path is arranged below the core 220, the aerosol needs to move in the -z direction. In this case, the aerosol generated by the susceptor 230 arranged on the upper surface of the core 220 can move through the hollow portion 220h in the -z direction.

[0248] The core 220 may include an engagement portion 221 protruding toward a storage unit (eg, the storage unit 210 of FIG. 4A ) such that at least a portion of an upper surface of the core 220 is spaced apart from the storage unit.

[0249] The engagement portion 221 may be arranged at an edge or end portion of the upper surface of the core 220 to contact the storage unit so that the remaining portion of the upper surface of the core 220 where the engagement portion 221 is not arranged is spaced apart from the storage unit. However, the arrangement structure of the engagement portion is not limited to this embodiment.

[0250] The joint portion 221 may absorb the aerosol generating substance supplied from the storage unit and transfer the aerosol generating substance to the entire area of ​​the core 220 .

[0251] If the air flow path (e.g., the air flow path 250 of FIG. 4A ) is arranged above the core 220 and thus the aerosol needs to move in the +z direction, the aerosol generated by the susceptor 230 arranged on the upper surface of the core 220 may flow through the space formed by the joint portion 221. In addition, the aerosol generated by the susceptor (not shown) arranged on the side surface of the core 220 may move to the space formed by the joint portion 221.

[0252] The aerosol collected in the space formed by the joining unit portion 221 may move toward the air flow path.

[0253] Fig.14 is a perspective view showing a susceptor integrated with a core according to an embodiment.

[0254] Reference Fig.14 According to an embodiment, the cartridge 20 may include a susceptor 260 formed integrally with the core.

[0255] The susceptor 260 formed integrally with the core can absorb the aerosol generating substance supplied from the storage unit (e.g., the storage unit 210 of FIG. 4A ), and atomize the absorbed aerosol generating substance into an aerosol by generating heat in response to the induced magnetic field. In other words, the susceptor 260 formed integrally with the core can perform both Fig. 9 The functions of the core 220 and the susceptor 230 are shown.

[0256] Similar to the core 220 and the susceptor 230 shown in FIG4A , the susceptor 260 formed as one body with the core can be arranged below the storage unit of the cartridge. When the cartridge and the body (e.g., the body 10 of FIG4A ) are coupled to each other, the susceptor 260 can be arranged above the induction coil (e.g., the induction coil 110 of FIG4A ).

[0257] The susceptor 260 formed integrally with the core may include a porous body obtained by sintering metal powder, a mesh body in which metal in the form of a net (or mesh) is arranged, etc. The susceptor 260 may include SUS316L. However, the material of the susceptor 260 is not limited thereto, and the material of the susceptor 260 may include all types of materials capable of performing the functions of the core and the susceptor at the same time.

[0258] The cartridge 20 according to the embodiment may further include a support element (not shown). The support element may support the susceptor 260 formed integrally with the core inside the cartridge 20. The support element may include all types of materials capable of withstanding heat from the susceptor 260. The arrangement structure of the support element is not limited to this embodiment, and the support element may be included in the body.

[0259] The susceptor 260 formed integrally with the core may be both a core and a susceptor, and thus, aerosol may be generated when heat is generated inside and on all outer surfaces of the susceptor 260. When the susceptor 260 is formed integrally with the core, the heat generation area may be increased and ultimately the atomization performance may be improved, compared to an embodiment in which the core 220 and the susceptor 230 are formed separately and coupled to each other.

[0260] When the core 220 and the susceptor 230 are simply coupled to each other, the core 220 formed of cotton or silicon dioxide may be carbonized, and as a result, harmful substances may be generated. When a core including ceramics is used, the degree of carbonization of the core can be reduced. However, the ceramic core may generate ceramic powder, and harmful materials such as ceramic powder may be mixed with the aerosol and introduced into the user's mouth.

[0261] In contrast, the susceptor 260 formed as one piece with the core will not be carbonized due to heating, and thus will not produce harmful substances. Therefore, the cigarette cartridge 20 including the susceptor 260 formed as one piece with the core can reduce the harm to the user.

[0262] Fig.15 is a block diagram of an aerosol generating device 1500 according to another embodiment.

[0263] The aerosol generating device 1500 may include a controller 1510, a sensing unit 1520, an output unit 1530, a battery 1540, a heater 1550, a user input unit 1560, a memory 1570, and a communication unit 1580. However, the internal structure of the aerosol generating device 1500 is not limited to Fig.15 That is, it will be understood by those skilled in the art that, depending on the design of the aerosol generating device 1500, the components shown in FIG. Fig.15 Some of the components shown in the figure may be modified or new components may be added.

[0264] The sensing unit 1520 can sense the state of the aerosol generating device 1500 and the state around the aerosol generating device 1500, and send the sensed information to the controller 1510. Based on the sensed information, the controller 1510 can control the aerosol generating device 1500 to perform various functions, such as controlling the operation of the heater 1550, restricting smoking, determining whether an aerosol generating product (e.g., a cigarette, a cigarette cartridge, etc.) is used, displaying a notification, etc.

[0265] The sensing unit 1520 may include at least one of a temperature sensor 1522, an insertion detection sensor, and a suction sensor 1526, but is not limited thereto.

[0266] The temperature sensor 1522 can sense the temperature at which the heater 1550 (or the aerosol generating substance) is heated. The aerosol generating device 1500 may include a separate temperature sensor for sensing the temperature of the heater 1550, or the heater 1550 may be used as a temperature sensor. Alternatively, the temperature sensor 1522 may also be arranged around the battery 1540 to monitor the temperature of the battery 1540.

[0267] The insertion detection sensor 1524 can sense the insertion and / or removal of the aerosol generating article. For example, the insertion detection sensor 1524 can include at least one of a membrane sensor, a pressure sensor, an optical sensor, a resistance sensor, a capacitance sensor, an inductance sensor, and an infrared sensor, and the insertion detection sensor 1524 can sense a signal change according to the insertion and / or removal of the aerosol generating article.

[0268] The suction sensor 1526 can sense the user's suction based on various physical changes in the air flow channel or air flow path. For example, the suction sensor 1526 can sense the user's suction based on any one of temperature change, flow change, voltage change and pressure change.

[0269] The sensing unit 1520 may include at least one of the following: a temperature / humidity sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a gyroscope sensor, a position sensor (e.g., a global positioning system (GPS)), a proximity sensor, and a red, green, and blue (RGB) sensor (illuminance sensor) in addition to the temperature sensor 1522, the insertion detection sensor 1524, and the suction sensor 1526 described above. Since a person of ordinary skill in the art can intuitively infer the function of each of the sensors from the name of the sensor, a detailed description of the sensor may be omitted.

[0270] The output unit 1530 may output information about the state of the aerosol generating device 1500 and provide the information to the user. The output unit 1530 may include at least one of a display unit 1532, a tactile unit 1534, and a sound output unit 1536, but is not limited thereto. When the display unit 1532 and the touch pad form a layered structure to form a touch screen, the display unit 1532 may be used as an input device in addition to being used as an output device.

[0271] The display unit 1532 may provide the user with information about the aerosol generating device 1500 in a visual manner. For example, the information about the aerosol generating device 1500 may refer to various information, such as the charging / discharging state of the battery 1540 of the aerosol generating device 1500, the preheating state of the heater 1550, the insertion / removal state of the aerosol generating article, the state in which the use of the aerosol generating device 1500 is restricted (e.g., sensing an abnormal object), etc., and the display unit 1532 may output the information to the outside. The display unit 1532 may be, for example, a liquid crystal display panel (LCD), an organic light emitting diode (OLED) display panel, etc. In addition, the display unit 1532 may be in the form of a light emitting diode (LED) light emitting device.

[0272] The haptic unit 1534 may provide the user with information about the aerosol generating device 1500 in a tactile manner by converting an electrical signal into mechanical stimulation or electrical stimulation. For example, the haptic unit 1534 may include a motor, a piezoelectric element, or an electrical stimulation device.

[0273] The sound output unit 1536 may provide the user with information about the aerosol generating device 1500 in an auditory manner. For example, the sound output unit 1536 may convert an electrical signal into a sound signal and output the sound signal to the outside.

[0274] The battery 1540 may supply power for operating the aerosol generating device 1500. The battery 1540 may supply power so that the heater 1550 may be heated. In addition, the battery 1540 may supply power required for the other components (e.g., the sensing unit 1520, the output unit 1530, the user input unit 1560, the memory 1570, and the communication unit 1580) in the aerosol generating device 1500 to operate. The battery 1540 may be a rechargeable battery or a disposable battery. For example, the battery 1540 may be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0275] Heater 1550 can receive power from battery 1540 to heat the aerosol generating material. Fig.15 Although not shown in the figure, the aerosol generating device 1500 may further include a power conversion circuit (e.g., a direct current (DC) / DC converter) that converts the power of the battery 1540 and supplies the converted power to the heater 1550. In addition, when the aerosol generating device 1500 generates aerosol by an induction heating method, the aerosol generating device 1500 may further include a DC / alternating current (AC) that converts the DC power of the battery 1540 into AC power.

[0276] The controller 1510, the sensing unit 1520, the output unit 1530, the user input unit 1560, the memory 1570, and the communication unit 1580 may all receive power from the battery 1540 to perform functions. Fig.15 Although not shown, the aerosol generating device 1500 may further include a power conversion circuit that converts the power of the battery 1540 to supply power to corresponding components, such as a low dropout (LDO) circuit or a voltage regulator circuit.

[0277] In an embodiment, the heater 1550 may be formed of any suitable resistive material. For example, a suitable resistive material may be a metal or a metal alloy, including, but not limited to, titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nickel-chromium alloy, etc. In addition, the heater 1550 may be implemented by a metal wire, a metal plate arranged with an electrically conductive trace, a ceramic heating element, etc., but not limited to this.

[0278] In another embodiment, the heater 1550 may be an induction heating type heater. For example, the heater 1550 may include a susceptor that heats the aerosol generating substance by generating heat through a magnetic field applied by a coil.

[0279] The user input unit 1560 may receive information input from the user or may output information to the user. For example, the user input unit 1560 may include a keyboard, a dome switch, a touch pad (contact capacitance method, pressure resistance film method, infrared sensing method, surface ultrasonic conduction method, integral tension measurement method, piezoelectric effect method, etc.), a roller, a roller switch, etc., but is not limited thereto. In addition, although in Fig.15 Although not shown, the aerosol generating device 1500 may further include a connection interface, such as a universal serial bus (USB) interface, and the aerosol generating device 1500 may be connected to other external devices via the connection interface, such as the USB interface, to send and receive information or charge the battery 1540.

[0280] The memory 1570 is a hardware component that stores various types of data processed in the aerosol generating device 1500, and the memory 1570 can store data processed by the controller 1510 and to be processed by the controller 910. The memory 1570 may include at least one type of storage medium from the following: flash memory type, hard disk type, multimedia card micro memory, card type memory (such as secure digital (SD) or extreme digital (XD) memory, etc.), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk. The memory 1570 can store the following: the operation time of the aerosol generating device 1500, the maximum number of puffs, the current number of puffs, at least one temperature curve, data on the smoking pattern of the user, etc.

[0281] The communication unit 1580 may include at least one component for communicating with another electronic device. For example, the communication unit 1584 may include a short-range wireless communication unit 1582 and a wireless communication unit 984 .

[0282] The short-range wireless communication unit 1582 may include a Bluetooth communication unit, a Bluetooth low energy (BLE) communication unit, a near field communication unit, a wireless LAN (WLAN) (Wi-Fi) communication unit, a Zigbee communication unit, an infrared data association (IrDA) communication unit, a Wi-Fi Direct (WFD) communication unit, an ultra-wideband (UWB) communication unit, an Ant+ communication unit, etc., but is not limited to these.

[0283] The wireless communication unit 1584 may include, but is not limited to, a cellular network communication unit, an Internet communication unit, a computer network (e.g., a local area network (LAN) or a wide area network (WAN)) communication unit, etc. The wireless communication unit 1584 may also identify and authenticate the aerosol generating device 1500 within the communication network by using subscription information (e.g., an International Mobile Subscriber Identifier (IMSI)).

[0284] The controller 1510 may control the overall operation of the aerosol generating device 1500. In an embodiment, the controller 1510 may include at least one processor. The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program that can be executed by the microprocessor. It will be understood by those of ordinary skill in the art that the processor may be implemented in other forms of hardware.

[0285] The controller 1510 can control the temperature of the heater 1550 by controlling the power supplied from the battery 1540 to the heater 1550. For example, the controller 1510 can control the power supply by controlling the switching of the switching element between the battery 1540 and the heater 1550. In another example, the direct heating circuit can also control the power supply to the heater 1550 according to the control command of the controller 1510.

[0286] The controller 1510 may analyze the result sensed by the sensing unit 1520 and control the processing to be performed subsequently. For example, the controller 1510 may control the power supplied to the heater 1550 based on the result sensed by the sensing unit 1520 to start or end the operation of the heater 1550. As another example, the controller 1510 may control the amount of power supplied to the heater 1550 and the time when the power is supplied based on the result sensed by the sensing unit 1520, so that the heater 1550 can be heated to a specific temperature or maintained at an appropriate temperature.

[0287] The controller 1510 may control the output unit 1530 based on the result sensed by the sensing unit 1520. For example, when the number of puffs counted by the puff sensor 1526 reaches a preset number, the controller 1510 may notify the user through at least one of the display unit 1532, the tactile unit 1534, and the sound output unit 1536 that the aerosol generating device 1500 will soon be terminated.

[0288] An embodiment can also be implemented in the form of a computer-readable recording medium, which includes instructions that can be executed by a computer, such as a program module that can be executed by a computer. The computer-readable recording medium can be any available medium that can be accessed by a computer and includes volatile media and non-volatile media and removable media and non-removable media. In addition, the computer-readable recording medium may include both computer storage media and communication media.
