Description

Aerosol generating device

[0001] The embodiments relate to an aerosol generating device, and more particularly, to an aerosol generating device having a simplified structure and capable of effectively generating an aerosol from an aerosol generating material.

[0002] Recently, there has been a growing demand for technologies that replace the conventional method of producing aerosols by burning cigarettes. For example, research is underway into methods for producing aerosols from liquid or solid aerosol-generating substances, or for producing vapor from liquid aerosol-generating substances and then passing the vapor through a solid flavoring medium to produce a flavored aerosol.

[0003] An aerosol generating device capable of generating an aerosol from an aerosol generating substance in a liquid or gel state has the advantages of being small in size, easy to carry, clean and easy to use as no byproducts are generated during the aerosol generating process.

[0004] The aerosol generating device has an aerosol generating material, which is a material for generating an aerosol, and must minimize leakage of the aerosol generating material in a liquid state, a material that has changed into a liquid, or a liquid material generated by the re-liquefaction of an aerosol into the space where electronic components are located.

[0005] Since severe leakage may cause electronic components to malfunction or be damaged, a sealing structure that prevents liquid from flowing between the aerosol generator that creates the aerosol and the components that supply electricity to the aerosol generator is also considered.

[0006] In general, a sealing structure using a rubber ring is often considered for aerosol generating devices, but the number of parts increases to complete the sealing structure and the structure of the device becomes complex, making the design and assembly of the product difficult.

[0007] In addition, electrical energy must be supplied to the aerosol generator in order for the aerosol generator to generate aerosol, and there are technical difficulties in implementing a sealed structure while electrically connecting the aerosol generator and the component that supplies power.

[0008] The embodiments aim to provide an aerosol generating device having a simplified structure that can effectively generate an aerosol from an aerosol generating material in a liquid or gel state.

[0009] The embodiments also seek to provide an aerosol generating device with minimized leakage.

[0010] The embodiments also aim to provide an aerosol generating device having a complete sealing structure and an efficient electrical connection structure between components.

[0011] The embodiments also aim to provide an aerosol generating device that is easy to design for the arrangement of components and easy to assemble.

[0039] The terms used in the examples are selected from widely used, current terms, taking into account the functions of the present invention. However, these terms may vary depending on the intentions of those skilled in the art, precedents, the emergence of new technologies, etc. Furthermore, in certain cases, terms may be arbitrarily selected by the applicant, and in such cases, their meanings will be described in detail in the description of the relevant invention. Therefore, the terms used in the present invention should be defined based on their meaning and the overall content of the present invention, rather than simply their names.

[0040] When a part of the specification is said to "include" a component, unless otherwise specifically stated, this does not exclude other components but rather implies the inclusion of other components. Furthermore, terms such as "part" and "module" used in the specification refer to a unit that processes at least one function or operation, which may be implemented in hardware, software, or a combination of hardware and software.

[0041] As used herein, when an expression such as "at least one" precedes an array of elements, it modifies the entire array of elements, not just each individual element. For example, the expression "at least one of a, b, and c" should be interpreted to include a, b, c, or a and b, a and c, b and c, or a and b and c.

[0042] In one embodiment, the aerosol generating device may be a device that generates an aerosol using a cartridge containing an aerosol generating material.

[0043] An aerosol generating device may include a cartridge containing an aerosol generating substance and a body supporting the cartridge. The cartridge may be detachably coupled to the body, but is not limited thereto. The cartridge may be formed or assembled integrally with the body, and may be secured so as not to be detached by a user. The cartridge may be mounted to the body while containing the aerosol generating substance therein. However, this is not limited thereto, and the aerosol generating substance may be injected into the cartridge while the cartridge is coupled to the body.

[0044] The cartridge may contain an aerosol-generating substance in any one of a variety of states, such as a liquid state, a solid state, a gaseous state, or a gel state. The aerosol-generating substance may comprise a liquid composition. For example, the liquid composition may be a liquid comprising a tobacco-containing material including volatile tobacco flavoring components, or may be a liquid comprising a non-tobacco material.

[0045] The cartridge can be operated by an electric signal or wireless signal transmitted from the main body, thereby converting the phase of an aerosol-generating substance inside the cartridge into a gaseous phase to generate an aerosol. The aerosol may refer to a gas that is a mixture of vaporized particles generated from the aerosol-generating substance and air.

[0046] In another embodiment, the aerosol generating device may heat a liquid composition to generate an aerosol, and the generated aerosol may be delivered to the user through a cigarette. That is, the aerosol generated from the liquid composition may travel along an airflow path of the aerosol generating device, and the airflow path may be configured such that the aerosol may pass through the cigarette and be delivered to the user.

[0047] In another embodiment, the aerosol generating device may be a device that generates an aerosol from an aerosol generating material using an ultrasonic vibration method. In this case, the ultrasonic vibration method may refer to a method of generating an aerosol by atomizing the aerosol generating material with ultrasonic vibrations generated by a vibrator.

[0048] The aerosol generating device may include a vibrator, which may generate short-cycle vibrations to atomize the aerosol generating material. The vibrations generated by the vibrator may be ultrasonic vibrations, and the frequency range of the ultrasonic vibrations may be, but is not limited to, about 100 kHz to about 3.5 MHz.

[0049] The aerosol generating device may further include a wick that absorbs the aerosol generating substance. For example, the wick may be positioned to surround at least a portion of the vibrator or may be positioned to contact at least a portion of the vibrator.

[0050] When a voltage (e.g., an alternating current) is applied to the vibrator, heat and / or ultrasonic vibrations may be generated from the vibrator, and the heat and / or ultrasonic vibrations generated from the vibrator may be transmitted to an aerosol-generating substance absorbed in the wick. The aerosol-generating substance absorbed in the wick may be converted into a gaseous phase by the heat and / or ultrasonic vibrations transmitted from the vibrator, thereby generating an aerosol.

[0051] For example, the viscosity of an aerosol-generating substance absorbed into a wick may be lowered by heat generated from a vibrator, and an aerosol may be generated by fine particles of an aerosol-generating substance with a lowered viscosity due to ultrasonic vibration generated from a vibrator, but is not limited thereto.

[0052] In another embodiment, the aerosol generating device may be a device that generates an aerosol by heating an aerosol generating article accommodated in the aerosol generating device by induction heating.

[0053] An aerosol generating device may include a susceptor and a coil. In one embodiment, the coil may apply a magnetic field to the susceptor. As power is supplied to the coil from the aerosol generating device, a magnetic field may be formed within the coil. In one embodiment, the susceptor may be a magnetic material that generates heat due to an external magnetic field. When the susceptor is positioned within the coil and a magnetic field is applied, the susceptor generates heat, thereby heating the aerosol generating article. Additionally, optionally, the susceptor may be positioned within the aerosol generating article.

[0054] In another embodiment, the aerosol generating device may further comprise a cradle.

[0055] The aerosol generator can be configured as a system with a separate cradle. For example, the cradle can charge the aerosol generator's battery. Alternatively, the heater can be heated while the cradle and aerosol generator are combined.

[0056] Below, embodiments of the present disclosure are described in detail with reference to the attached drawings so that those skilled in the art can easily implement them. The present disclosure may be implemented in a form that can be implemented in the aerosol generating devices of the various embodiments described above, or may be implemented in various different forms and is not limited to the embodiments described herein.

[0057] Hereinafter, embodiments are described in detail with reference to the drawings.

[0058] FIG. 1 is a drawing illustrating an aerosol generating device according to one embodiment, and FIG. 2 is a drawing illustrating an aerosol generating device according to another embodiment.

[0059] Figures 1 and 2 illustrate an aerosol generating device (1) according to embodiments of the present disclosure.

[0060] Referring to FIGS. 1 and 2, an aerosol generating device (1) may include a main body (300) and an aerosol generator (100a). The aerosol generating device (1) may include at least one of a power source (11), a control unit (12), and a sensor (13). At least one of the power source (11), the control unit (12), and the sensor (13) may be disposed inside the main body (300). An aerosol generator (100a), which is an aerosol generating item, may be mounted on the main body (300). A user may inhale aerosol by placing a mouthpiece provided at one end of the aerosol generator (100a) in his / her mouth.

[0061] The aerosol generator (100a) may contain an aerosol generating material in any one of a liquid state, a solid state, a gaseous state, or a gel state in an internal chamber (C0). 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 flavoring component, or may be a liquid containing a non-tobacco material.

[0062] The aerosol generating device (1) may include a hollow case (310). The case (310) is integrally formed with a partition wall (310w) that divides the case (310) into a first zone (311) and a second zone (312).

[0063] The aerosol generator (100a) and the main body (300) can be detachably coupled to the case (310). The aerosol generator (100a) is located in the first section (311) of the case (310). The main body (300) is located in the second section (312) of the case (310). The aerosol generator (100a) can be referred to as a 'cartridge'.

[0064] When the aerosol generator (100a) is inserted into the case (310), the generator terminal (100t) of the aerosol generator (100a) can be electrically connected to the main body terminal (320) of the main body (300). The partition wall (310w) includes a through hole (310h) through which the main body terminal (320) passes.

[0065] The main body (300) may be formed in a structure in which outside air can be introduced into the interior of the main body (300) while the aerosol generator (100a) is inserted into the case (310). At this time, the outside air introduced into the main body (300) can pass through the aerosol generator (100a) and flow into the user's oral cavity through the airflow channel (CN).

[0066] The aerosol generator (100a) may include a chamber (C0) containing an aerosol generating material and / or a heater (24) for heating the aerosol generating material in the chamber (C0). A liquid delivery means (25) impregnating (containing) the aerosol generating material may be disposed inside the chamber (C0). Here, the liquid delivery means (25) may include a wick such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, etc. The electrically conductive track of the heater (24) may be formed in a coil-shaped structure that winds the liquid delivery means (25) or a structure that contacts one side of the liquid delivery means (25). The heater (24) may be referred to as a cartridge heater.

[0067] An aerosol generator (100a) can generate an aerosol. As the liquid delivery means (25) is heated by the cartridge heater (24), an aerosol can be generated. The generated aerosol can be inhaled into the user's oral cavity through the airflow channel (CN).

[0068] An airflow channel (CN) may be provided in the aerosol generator (100a). The airflow channel (CN) may communicate with the chamber in which the heater (24) of the aerosol generator (100a) is arranged and the outside of the cartridge. One end of the airflow channel (CN) may be opened to the chamber in which the heater (24) is arranged, and the other end may be communicated with the mouthpiece. For example, referring to FIG. 1, the airflow channel (CN) may extend in a longitudinal direction of the aerosol generator (100a) from one side of the chamber (C0) of the aerosol generator (100a). For example, referring to FIG. 2, the airflow channel (CN) may extend in a longitudinal direction of the aerosol generator (100a) by penetrating the chamber (C0) of the aerosol generator (100a).

[0069] The power source (11) can supply power to operate components of the aerosol generating device. The power source (11) can be referred to as a battery. The power source (11) can supply power to at least one of the control unit (12), the sensor (13), and the cartridge heater (24).

[0070] The control unit (12) can control the overall operation of the aerosol generating device. The control unit can be mounted on a printed circuit board (PCB). The control unit (12) can control the operation of at least one of the power supply (11), the sensor (13), and the aerosol generator (100a). The control unit (12) can control the operation of a display, a motor, etc. installed in the aerosol generating device. The control unit (12) can check the status of each component of the aerosol generating device to determine whether the aerosol generating device is in an operable state.

[0071] The control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the cartridge heater (24) so ​​that the operation of the cartridge heater (24) is started or ended based on the results detected by the sensor (13). For example, the control unit (12) can control the amount of power supplied to the cartridge heater (24) and the time for which the power is supplied so that the cartridge heater (24) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor (13).

[0072] The sensor (13) may include at least one of a temperature sensor, a puff sensor, a cartridge detection sensor, and a movement detection sensor. For example, the sensor (13) may sense at least one of the temperature of the cartridge heater (24), the temperature of the power source (11), and the temperature inside and outside the main body (300). For example, the sensor (13) may sense the user's puff. For example, the sensor (13) may sense whether the cartridge is mounted. For example, the sensor (13) may sense the movement of the aerosol generating device.

[0073] FIG. 3 is a perspective view illustrating an aerosol generating device according to another embodiment.

[0074] The aerosol generating device (1) according to the embodiment illustrated in FIG. 3 includes an aerosol generator (100a), a main body (300), and a case (310).

[0075] The case (310) has a hollow shape with an interior that is empty and both ends open to the outside. At least a portion of the aerosol generator (100a) is inserted into the case (310), and the aerosol generator (100a) is coupled to one side of the case (310). A portion or the entire body (300) is inserted into the case (310), and the body (300) is coupled to the other side of the case (310).

[0076] The case (310) extends along the circumferential direction to surround each of the aerosol generator (100a) and the main body (300) located in the case (310). The case (310) includes a first hole (311a) and a second hole (312a) for exposing each portion of the aerosol generator (100a) and the main body (300) to the outside of the case (310).

[0077] A portion of the aerosol generator (100a) positioned in the case (310) can protrude outside the case (310) through the first hole (311a). A portion of the main body (300) positioned in the case (310) can protrude outside the case (310) through the second hole (312a).

[0078] By allowing a portion of the aerosol generator (100a) and a portion of the main body (300) to protrude outside the case (310) through the first hole (311a) and the second hole (312a), the overall design of the aerosol generator (1) can be elegantly completed.

[0079] In addition, since a part of the aerosol generator (100a) and a part of the main body (300) protrude outside the case (310) through the first hole (311a) and the second hole (312a), when separating the aerosol generator (100a) or the main body (300) from the case (310), the user can hold a part of the aerosol generator (100a) or the main body (300) by hand, making the separation operation convenient.

[0080] An aerosol generator (100a) may include a cartridge (100) and a generator module (200). An aerosol generating substance may be stored inside the cartridge (100). The aerosol generating substance stored in the cartridge (100) may be supplied to a generator module (200) positioned at the bottom (e.g., the portion facing the -y direction) of the cartridge (100).

[0081] The generator module (200) is located between the cartridge (100) and the main body (300) and can perform the function of generating an aerosol by converting the phase of an aerosol generating material into a gas phase. The generator module (200) can generate an aerosol by heating the aerosol generating material supplied from the cartridge (100).

[0082] 'Aerosol' can mean gas particles created by mixing air with vapor generated by heating an aerosol-generating substance.

[0083] The cartridge (100) may include a mouthpiece (100m) for supplying an aerosol to a user. For example, the mouthpiece (100m) may be connected to the interior of the generator module (200) and / or the exterior of the aerosol generating device (1) to allow air and aerosol to flow.

[0084] The aerosol generated inside the generator module (200) can be discharged to the outside of the aerosol generating device (1) through the mouth piece (100 m). The user can contact the mouth to the mouth piece (100 m) and inhale the aerosol discharged to the outside of the aerosol generating device (1).

[0085] For example, the generator module (200) can heat an aerosol generating material supplied from a cartridge (100) to generate vapor from the aerosol generating material. The vapor generated in the generator module (200) can be mixed with external air introduced into the interior of the generator module (200) from the outside of the generator module (200) to generate an aerosol.

[0086] As another example, the generator module (200) may generate an aerosol from an aerosol generating material using an ultrasonic vibration method. The ultrasonic vibration method may refer to a method of generating an aerosol by atomizing an aerosol generating material using ultrasonic vibrations generated by a vibrator.

[0087] As another example, the generator module (200) can generate an aerosol by heating an aerosol generating material accommodated in an aerosol generating device using an induction heating method.

[0088] The main body (300) is located at the bottom (e.g., the end facing the -y direction) of the generator module (200). Components for the operation of the aerosol generating device (1) may be arranged inside the main body (300). For example, a battery (not shown), a processor (not shown), a user interface, and sensors may be arranged inside the main body (300).

[0089] FIG. 4 is a perspective view showing the components of the aerosol generating device according to the embodiment illustrated in FIG. 3 in isolation.

[0090] The case (310) can serve to protect and support components of the aerosol generating device (1). The case (310) has a hollow shape with an empty interior. A partition wall (310w) is formed inside the case (310). The case (310) and the partition wall (310w) are formed integrally.

[0091] The case (310) and the partition wall (310w) being 'formed as one piece' may mean, for example, that the case (310) and the partition wall (310w) are manufactured as one body without using a separate assembly or attachment process. In order for the case (310) and the partition wall (310w) to be 'formed as one piece', the case (310) and the partition wall (310w) may be made of the same material.

[0092] As an example, the case (310) and the partition wall (310w) can be formed integrally by injection molding by applying the same resin material to the case (310) and the partition wall (310w).

[0093] As another example, the raw material of the body made of metal or plastic may be processed to form the case (310) and the partition wall (310w) integrally. The case (310) and the partition wall (310w) may be formed integrally by preparing a raw material having a columnar or hexahedral shape and removing a portion of the raw material mechanically or chemically, such as etching.

[0094] As another example, the case (310) and the partition wall (310w) can be formed integrally by a 3D printing method.

[0095] As another example, the case (310) and the partition wall (310w) may be formed integrally by forming one of the case (310) and the partition wall (310w) from, for example, a plastic material and forming the other from, for example, a metal material. For example, the case (310) and the partition wall (310w) may be formed integrally by first processing a hollow case (310) using a metal pipe material, then placing the metal case (310) in a mold and injecting resin into the mold using a method such as insert molding or heterogeneous material injection.

[0096] The partition wall (310w) can divide the area inside the case (310) into a first zone (311) and a second zone (312). The first zone (311) and the second zone (312) divided by the partition wall (310w) can be arranged along the direction in which the case (310) extends, i.e., along the longitudinal direction of the case (310).

[0097] In Fig. 4, a portion of the case (310) surrounding the first zone (311) is omitted for the purpose of illustrating the first zone (311) and the partition wall (310w).

[0098] The case (310) surrounds at least a portion of the aerosol generator (100a) and / or the main body (300). The case (310) can maintain the positions of the components and protect the components from external impact or inflow of foreign substances.

[0099] The aerosol generator (100a) is located in the first zone (311) of the case (310). The main body (300) is located in the second zone (312) of the case (310). At least one of the aerosol generator (100a) and the main body (300) can be detachably coupled to the case (310). For example, the main body (300) can be fixed to the second zone (312) of the case (310), and the aerosol generator (100a) can be detachably coupled to the first zone (311).

[0100] The cartridge (100) may include a storage tank (110) in which an aerosol generating substance is stored. When the cartridge (100) and the generator module (200) are combined, the storage tank (110) is connected to the generator module (200) so that the aerosol generating substance in the storage tank (110) can flow into the generator module (200).

[0101] The aerosol generating material stored in the storage tank (110) may include a tobacco-containing material including a volatile tobacco flavor component, or may include a liquid composition including a non-tobacco material.

[0102] The liquid composition may include any one or a mixture of water, solvent, ethanol, plant extracts, flavorings, flavoring agents, and vitamin mixtures. The flavoring agents may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit-flavored ingredients. The flavoring agents may include ingredients that provide a variety of flavors or tastes to the user. The vitamin mixture may include, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also include an aerosol-forming agent such as glycerin and propylene glycol.

[0103] The liquid composition may comprise a solution of glycerin and propylene glycol in any weight ratio to which a nicotine salt is added. The liquid composition may also comprise two or more nicotine salts. The nicotine salt may be formed by adding a suitable acid, including an organic or inorganic acid, to nicotine. The nicotine may be naturally occurring nicotine or synthetic nicotine, and may have any suitable weight concentration relative to the total solution weight of the liquid composition.

[0104] The acid for forming the nicotine salt may be appropriately selected in consideration of the rate of nicotine absorption in the blood, the operating temperature of the aerosol generating device (1), flavor or taste, solubility, etc. For example, the acid for forming the nicotine salt may be a single acid selected from the group consisting of benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid, or malic acid, or a mixture of two or more acids selected from the group, but is not limited thereto.

[0105] The generator module (200) can generate an aerosol by heating an aerosol generating material supplied from a storage tank (110) of a cartridge (100). The generator module (200) can be detachably coupled to the cartridge (100). For example, the generator module (200) can be detachably coupled to a lower surface (e.g., a surface facing the -y direction) of the cartridge (100).

[0106] When the aerosol generating substance stored in the storage tank (110) of the cartridge (100) is exhausted, the used cartridge (100) can be replaced with a new cartridge (100). According to the structure in which the generator module (200) and the cartridge (100) are detachably coupled, only the cartridge (100) in which the aerosol generating substance has been exhausted can be replaced and the generator module (200) can be reused. By replacing only the cartridge (100) and reusing the generator module (200), the cost of using the aerosol generating device (1) can be reduced.

[0107] Additionally, if the performance of the generator module (200) deteriorates or its lifespan ends and a sufficient amount of aerosol is not generated, the existing generator module (200) can be separated from the case (310) and a new generator module (200) can be combined with the case (310).

[0108] However, the embodiments are not limited to the structure in which the cartridge (100) and the generator module (200) illustrated in FIG. 4 are detachably coupled. For example, the structure illustrated in FIG. 4 may be modified so that the cartridge (100) and the generator module (200) are manufactured as a single component so that the cartridge (100) and the generator module (200) cannot be detached.

[0109] The generator module (200) may include an aerosol generating material inlet (201) connecting the interior of the generator module (200) and the storage tank (110), an air inlet (202) for introducing external air into the generator module (200), and an air outlet (203) for discharging aerosol generated in the generator module (200) to a cartridge (100).

[0110] When the cartridge (100) and the generator module (200) are combined, the aerosol generating material in the storage tank (110) of the cartridge (100) can be introduced into the generator module (200) through the aerosol generating material inlet (201). A heater (not shown) placed in the generator module (200) can heat the aerosol generating material supplied from the storage tank (110).

[0111] Outside air can be introduced into the generator module (200) through the air inlet (202). The outside air introduced into the generator module (200) can be mixed with vapor generated from an aerosol generating material to generate an aerosol.

[0112] The aerosol generated in the generator module (200) can be transferred to the cartridge (100) through the air outlet (203) and then discharged to the outside of the cartridge (100) through the mouth piece (100m). For example, when a user puts the mouth piece (100m) in his / her mouth and inhales, the pressure inside the cartridge (100) decreases, so that the aerosol of the generator module (200) is transferred to the cartridge (100). Therefore, the user can inhale the aerosol through the mouth piece (100m).

[0113] The main body (300) is coupled to the second section (312) of the case (310) so as to correspond to the lower surface (e.g., the surface facing the -y direction) of the generator module (200). For example, the main body (300) may be fixed to the case (310). As another example, the main body (300) may be detachably coupled to the case (310).

[0114] The main body (300) may include components for the operation of the aerosol generating device (1). For example, the main body (300) may include a battery (not shown) for power supply and a processor (not shown) for controlling the aerosol generating operation of the aerosol generating device (1).

[0115] The battery can supply power used for the operation of the aerosol generating device (1). For example, the battery can be electrically connected to the generator module (200) to supply power to the heater of the generator module (200). The battery can also supply power required for the operation of other components of the aerosol generating device (1) other than the generator module (200).

[0116] Additionally, the control unit of the main body (300) can control the power supplied to the heater of the generator module (200) and / or control the operation of the generator module (200). For example, the control unit can control the amount of power supplied from the battery to the heater and the time for which the power is supplied so that the heater of the generator module (200) can be heated to a predetermined temperature or maintained at a predetermined temperature.

[0117] The main body (300) includes a main body terminal (320) for supplying electricity to the aerosol generator (100a). The main body terminal (320) may include an electrical terminal for supplying power to the battery of the main body (300) and / or a signal terminal for supplying an electrical control signal to the control unit of the main body (300).

[0118] The main body (300) includes a terminal support portion (320s) formed to protrude at the upper end facing the aerosol generator (100a). The outer diameter or width of the terminal support portion (320s) is formed to be smaller than the diameter or width of the main body (300).

[0119] When the main body (300) is positioned in the second zone (312) of the case (310), the outer surface of the terminal support portion (320s) comes into contact with the inner wall of the second zone (312), so that the main body (300) is stably supported by the case (310).

[0120] The partition wall (310w) includes a through hole (310h) connecting the first zone (311) and the second zone (312). The body terminal (320) of the main body (300) can pass through the through hole (310h) of the partition wall (310w) so that an end of the body terminal (320) can protrude toward the first zone (311). By contacting the body terminal (320) with the aerosol generator (100a), the body terminal (320) can be electrically connected to the aerosol generator (100a).

[0121] Additionally, the partition wall (310w) includes an air hole (310a) that fluidly connects the first zone (311) and the second zone (312). The air hole (310a) transfers air introduced from the outside of the case (310) into the second zone (312) to the first zone (311). The air transferred to the first zone (311) through the air hole (310a) is supplied to the air inlet (202) of the generator module (200).

[0122] A sealing member (317) may be placed between the partition wall (310w) and the main body (300). The sealing member (317) may be coupled to the outside of the main body terminal (320). When the main body terminal (320) is inserted into the through hole (310h), the sealing member (317) is positioned between the through hole (310h) of the partition wall (310w) and the main body terminal (320), thereby sealing the through hole (310h).

[0123] The sealing portion (317) may have, for example, the shape of an elastic ring. The sealing portion (317) may be implemented in various ways, for example, the sealing portion (317) may be implemented by any one or a combination of rubber materials, waterproof tape, waterproof adhesive or paint, and waterproof sponge.

[0124] The first zone (311) and the second zone (312) of the case (310) are isolated from each other by a partition wall (310w) integrally formed in the case (310). Therefore, even if the aerosol generated from the aerosol generator (100a) is liquefied again to create a liquid or the liquid leaks from the aerosol generator (100a), the partition wall (310w) can prevent the liquid from flowing into the second zone (312).

[0125] If the case (310) and the partition wall (310w) of the aerosol generator (1) are not formed integrally, it is difficult to implement a sealing structure between the parts. For example, in order to implement a sealing structure in the space between the case (310) of the aerosol generator (100a) and the aerosol generator (100a) and in the space between the main body (300) and the aerosol generator (100a), various sealing parts must be installed.

[0126] In addition, in order to prevent the liquid of the aerosol generator (100a) from flowing into the main body (300), the gap between the case (310) and the aerosol generator (100a) must be minimized. Therefore, if the case (310) and the partition wall (310w) are not formed integrally, the design and assembly of the aerosol generator (1) become difficult.

[0127] In addition, according to the aerosol generating device (1) according to the embodiment, the cartridge (100) and the generator module (200) are detachably coupled, so that the cartridge (100) and / or the generator module (200) can be conveniently replaced.

[0128] Figure 5 is a cross-sectional view of an aerosol generating device according to another embodiment.

[0129] The aerosol generating device according to the embodiment shown in Fig. 5 includes a hollow case (310), an aerosol generator (100a) and a main body (300) positioned in the case (310), and a partition wall (310w) integrally formed in the case (310) to partition the interior of the case (310).

[0130] The case (310) and the partition wall (310w) are formed of the same material. For example, the case (310) and the partition wall (310w) may include the same resin material. For example, the case (310) and the partition wall (310w) may be integrally formed by injection molding using a resin material.

[0131] The partition wall (310w) can partition the internal space of the case (310) into a first zone (311) and a second zone (312). The partition wall (310w) includes a through hole (310h) that connects the first zone (311) and the second zone (312).

[0132] The aerosol generator (100a) is positioned in the first zone (311), and the main body (300) is positioned in the second zone (312). When the aerosol generator (100a) is positioned in the first zone (311), the generator support protrusion (300p) of the first zone (311) is inserted into the generator groove (100g) formed on the outer surface of the aerosol generator (100a). The aerosol generator (100a) can be stably maintained in the first zone (311) of the case (310) by the combined structure of the generator groove (100g) and the generator support protrusion (300p).

[0133] The arrangement positions and numbers of the generator grooves (100g) and the generator support protrusions (300p) can be varied. For example, the generator grooves (100g) may be arranged in the first zone (311) and the generator support protrusions (300p) may be arranged in the aerosol generator (100a). Alternatively, the grooves and protrusions may be arranged in the aerosol generator (100a), and the grooves and protrusions may be arranged in the first zone (311) corresponding to the grooves and protrusions of the aerosol generator (100a), respectively.

[0134] When the main body (300) is positioned in the second zone (312), the main body support protrusion (301p) of the second zone (312) is inserted into the main body groove (300g) formed on the outer surface of the main body (300). The main body (300) can be stably maintained in the second zone (312) of the case (310) by the joint structure of the main body groove (300g) and the main body support protrusion (301p).

[0135] The arrangement positions and numbers of the main body grooves (300g) and the main body support protrusions (301p) can be varied. For example, the main body grooves (300g) can be arranged in the second zone (312), and the main body support protrusions (301p) can be arranged in the main body (300). Alternatively, the grooves and protrusions can be arranged in the main body (300), and the protrusions and grooves can be arranged in the second zone (312) corresponding to the grooves and protrusions of the main body (300), respectively.

[0136] The main body (300) includes a main body terminal (320) for providing electricity to the aerosol generator (100a). The main body (300) includes a terminal support portion (320s) protruding toward the aerosol generator (100a).

[0137] The case (310) includes a support wall (318) extending circumferentially along the inner wall of the case (310) at the edge of the partition wall (310w) in the second zone (312). The outer surface of the terminal support portion (320s) of the main body (300) located in the second zone (312) contacts the support wall (318). The outer surface of the terminal support portion (320s) can be stably supported by the support wall (318).

[0138] When the main body (300) is positioned in the second zone (312) of the case (310), the outer surface of the terminal support portion (320s) comes into contact with the second zone (312), so that the main body (300) is stably supported by the case (310).

[0139] The partition wall (310w) includes a through hole (310h) connecting the first zone (311) and the second zone (312). An end of a body terminal (320) of the main body (300) can pass through the through hole (310h) of the partition wall (310w) and protrude toward the first zone (311). By contacting the body terminal (320) with the aerosol generator (100a), the body terminal (320) can be electrically connected to the generator terminal (100t) of the aerosol generator (100a).

[0140] In addition, the partition wall (310w) includes an air hole (310a) that fluidly connects the first zone (311) and the second zone (312). The case (310) includes an inlet hole (310i) for introducing external air into the case (310). Since the inlet hole (310i) is connected to the air hole (310a), air introduced from the outside of the case (310) is delivered to the first zone (311) through the air hole (310a). The air delivered to the first zone (311) through the air hole (310a) is supplied to the inlet (106) of the aerosol generator (100a).

[0141] The air supplied to the inlet (106) of the aerosol generator (100a) flows into the chamber (100c) where the aerosol is generated, and the aerosol formed in the chamber (100c) is mixed with the air and discharged to the outside through the outlet (107) of the aerosol generator (100a).

[0142] A sealing portion (317) may be placed between the partition wall (310w) and the main body (300). The sealing portion (317) may be located on the outside of the main body terminal (320). The sealing portion (317) is located between the lower surface of the partition wall (310w) and the upper surface of the terminal support portion (320s), thereby sealing the space between the through hole (310h) and the second zone (312). The sealing portion (317) functions to seal the space between the first zone (311) and the second zone (312) so as to prevent liquid that may be generated in the first zone (311) from flowing into the second zone (312).

[0143] Figure 6 is a cross-sectional view of an aerosol generating device according to another embodiment.

[0144] The aerosol generating device according to the embodiment shown in Fig. 6 includes a hollow case (310), an aerosol generator (100a) and a main body (300) positioned in the case (310), and a partition wall (310w) integrally formed in the case (310) to partition the interior of the case (310).

[0145] The case (310) and the partition wall (310w) include a metal body (310m) and a plastic layer (310p). The metal body (310m) may include one or more of steel, aluminum, and stainless steel, or an alloy of several metals.

[0146] The metal body (310m) and the plastic layer (310p) can be formed integrally. For example, a metal body (310m) having a pipe or cylinder shape made of metal material can be placed in a mold, and then a plastic layer (310p) can be formed integrally on the surface of the metal body (310m) by insert molding, which involves injecting molten resin into the mold and curing the resin.

[0147] According to the structure of the case (310) in which the metal body (310m) and the plastic layer (310p) are integrally formed, the overall rigidity of the case (310) is improved by the metal body (310m). In addition, the plastic layer (310p) integrally formed on the surface of the metal body (310m) can provide various colors and textures to the exterior of the aerosol generating device. In addition, the plastic layer (310p) can enhance the corrosion resistance of the case (310) and reduce damage to the surface of the case (310) due to scratches.

[0148] The partition wall (310w) can partition the internal space of the case (310) into a first zone (311) and a second zone (312). The partition wall (310w) includes a through hole (310h) that connects the first zone (311) and the second zone (312).

[0149] The case (310) includes a support wall (318) extending circumferentially along the inner wall of the case (310) at the edge of the partition wall (310w) in the first zone (311). The outer surface of the aerosol generator (100a) located in the first zone (311) contacts the support wall (318). The outer surface of the aerosol generator (100a) can be stably supported by the support wall (318).

[0150] When the aerosol generator (100a) is located in the first zone (311) and the main body (300) is located in the second zone (312), the main body (300) is electrically connected to the aerosol generator (100a) through the partition wall (310w).

[0151] The main body (300) includes a main body terminal (320) for providing electricity to the aerosol generator (100a). The aerosol generator (100a) includes a generator terminal (100t) protruding toward the main body (300).

[0152] The partition wall (310w) includes a through hole (310h) connecting the first zone (311) and the second zone (312). An end of the generator terminal (100t) of the aerosol generator (100a) can pass through the through hole (310h) of the partition wall (310w) and protrude toward the second zone (312). When the generator terminal (100t) of the aerosol generator (100a) comes into contact with the main body terminal (320), the main body terminal (320) and the generator terminal (100t) can be electrically connected.

[0153] Fig. 7 is a cross-sectional view of an aerosol generating device according to another embodiment.

[0154] The aerosol generating device according to the embodiment shown in Fig. 7 includes a hollow case (310), an aerosol generator (100a) positioned in the case (310), a main body (300), and a partition wall (310w) integrally formed in the case (310) to partition the interior of the case (310) into a first zone (311) and a second zone (312).

[0155] The case (310) and the partition wall (310w) can be formed integrally, for example, by injection molding using the same resin material.

[0156] The partition wall (310w) includes a through hole (310h) that penetrates the partition wall (310w) from the first zone (311) toward the second zone (312). A connection terminal (320t) is arranged in the through hole (310h). The connection terminal (320t) includes an electrically conductive material.

[0157] The generator terminal (100t) of the aerosol generator (100a) located in the first zone (311) of the case (310) contacts the upper surface of the connection terminal (320t). The body terminal (320) of the main body (300) located in the second zone (312) of the case (310) contacts the lower surface of the connection terminal (320t). Therefore, when the aerosol generator (100a) and the main body (300) are located in the case (310), the generator terminal (100t) and the main body terminal (320) are electrically connected by the connection terminal (320t).

[0158] The connection terminal (320t) may be formed integrally with the partition wall (310w) of the case (310). For example, the case (310) and the connection terminal (320t) may be formed integrally by insert injection, which involves placing the connection terminal (320t) of an electrically conductive material in a mold, injecting molten resin into the mold, and curing the resin.

[0159] The case (310) includes a support wall (318b) extending circumferentially along the inner wall of the case (310) at the edge of the partition wall (310w) in the first zone (311). The outer surface of the aerosol generator (100a) located in the first zone (311) contacts the support wall (318b). The outer surface of the aerosol generator (100a) can be stably supported by the support wall (318b).

[0160] The case (310) includes a support wall (318) extending circumferentially along the inner wall of the case (310) at the edge of the partition wall (310w) in the second zone (312). The outer surface of the main body (300) located in the second zone (312) contacts the support wall (318). The outer surface of the main body (300) can be stably supported by the support wall (318).

[0161] According to the aerosol generating device according to the embodiment illustrated in Fig. 7, the first zone (311) and the second zone (312) inside the case (310) can be maintained in a sealed state with each other by the partition wall (310w). Therefore, even if a liquid leak occurs in the aerosol generator (100a) located in the first zone (311) or the aerosol is liquefied again to generate liquid, the liquid can be prevented from leaking into the second zone (312).

[0162] In addition, while maintaining a sealed state between the first zone (311) and the second zone (312), the electrical connection function between the components by the connection terminal (320t) can be reliably implemented. That is, the electrical connection structure between the aerosol generator (100a) of the first zone (311) and the main body (300) of the second zone (312) can be stably established by the connection terminal (320t) integrally formed in the partition wall (310w).

[0163] Fig. 8 is a cross-sectional view of an aerosol generating device according to another embodiment.

[0164] The aerosol generating device according to the embodiment shown in Fig. 8 includes a hollow case (310), an aerosol generator (100a) and a main body (300) positioned in the case (310), and a partition wall (310w) integrally formed in the case (310) to partition the interior of the case (310).

[0165] The case (310) includes a metal body (310m), a plastic layer (310p), and a partition wall (310w). The metal body (310m) may include one or more alloys of steel, aluminum, and stainless steel.

[0166] The metal body (310m), the plastic layer (310p), and the partition wall (310w) can be formed integrally. For example, the case (310) can be manufactured by insert injection, which places a metal body (310m) having a pipe or barrel shape made of metal material in a mold, then injects molten resin into the mold and hardens the resin. By insert injection, the plastic layer (310p) can be integrally formed on the surface of the metal body (310m), and at the same time, the partition wall (310w) can be integrally formed inside the metal body (310m).

[0167] The partition wall (310w) can partition the internal space of the case (310) into a first zone (311) and a second zone (312). The partition wall (310w) includes a through hole (310h) that connects the first zone (311) and the second zone (312).

[0168] The partition wall (310w) includes a through hole (310h) connecting the first zone (311) and the second zone (312). An end of the body terminal (320) of the main body (300) can pass through the through hole (310h) of the partition wall (310w) and protrude toward the first zone (311). By contacting the body terminal (320) with the aerosol generator (100a), the body terminal (320) can be electrically connected to the aerosol generator (100a).

[0169] According to the structure of the case (310) in which the metal body (310m), the plastic layer (310p), and the partition wall (310w) are integrally formed, the overall rigidity of the case (310) is improved by the metal body (310m). In addition, the plastic layer (310p) integrally formed on the surface of the metal body (310m) can provide various colors and textures to the exterior of the aerosol generating device. In addition, the plastic layer (310p) can enhance the corrosion resistance of the case (310) and reduce damage to the surface of the case (310) due to scratches.

[0170] FIG. 9 is a block diagram for explaining an aerosol generating device according to the embodiments illustrated in FIGS. 2 to 8.

[0171] The aerosol generating device (1) may include a control unit (1000) (e.g., the control unit (12) of FIGS. 1 and 2), a sensing unit (2000) (e.g., the sensor (13) of FIGS. 1 and 2), an output unit (3000), a battery (4000) (e.g., the power supply (11) of FIGS. 1 and 2), a heater (5000) (e.g., the heater (24) of FIGS. 1 and 2), a user input unit (6000), a memory (7000), and a communication unit (8000). However, the internal structure of the aerosol generating device (1) is not limited to that shown in the drawings. That is, a person having ordinary skill in the art related to the present embodiment will understand that, depending on the design of the aerosol generating device (1), some of the components shown in the drawings may be omitted or new components may be added.

[0172] The sensing unit (2000) can detect the state of the aerosol generating device (1) or the state around the aerosol generating device (1) and transmit the detected information to the control unit (1000). Based on the detected information, the control unit (1000) can control the aerosol generating device (1) so that various functions such as controlling the operation of the heater (5000), restricting smoking, determining whether an aerosol generating article (e.g., cigarette, cartridge, etc.) is inserted, and displaying a notification are performed.

[0173] The sensing unit (2000) may include at least one of a temperature sensor (2100), an insertion detection sensor (2200), and a puff sensor (2300), but is not limited thereto.

[0174] The temperature sensor (2100) can detect the temperature at which the heater (5000) (or the aerosol generating material) is heated. The aerosol generating device (1) may include a separate temperature sensor that detects the temperature of the heater (5000), or the heater (5000) itself may function as a temperature sensor. Alternatively, the temperature sensor (2100) may be placed around the battery (4000) to monitor the temperature of the battery (4000).

[0175] The insertion detection sensor (2200) can detect the insertion and / or removal of an aerosol-generating article.
