Description

Aerosol generating device including a flavoring module

[0001] The various embodiments disclosed in this document relate to an aerosol generating device including a flavoring module.

[0002] Recently, there has been an increasing demand for alternative products that overcome the disadvantages of traditional cigarettes. For example, there is an increasing demand for devices that generate aerosols by electrically heating a cigarette stick (e.g., heated tobacco products). Accordingly, research on cigarette sticks (or aerosol generating products) and electric heating aerosol generating devices into which the cigarette stick is inserted is actively underway.

[0003] For example, an aerosol generating device generates aerosols by atomizing a liquid aerosol generating material. The aerosol generating device can provide users with diverse usage experiences by adding flavor to unscented aerosol generating materials or flavor-free aerosol generating materials.

[0004] The aforementioned background technology is one that the inventor possessed or acquired in the process of deriving the content of the disclosure of the present application, and it cannot be considered as prior art disclosed to the general public prior to the filing of this application.

[0005] Since flavor depends on user preferences, there were difficulties in providing a variety of flavors with aerosol generators; furthermore, there was a technical need for an aerosol generator that could add flavors to the aerosol according to user preferences or allow users to select and easily replace flavors.

[0006] Furthermore, if liquid aerosol generating material leaks from the aerosol generating device, the uniformity of the aerosol may be compromised, and there is a risk of malfunction or failure of the device. Therefore, the aerosol generating device needs to reduce or prevent liquid leakage.

[0007] However, the problems to be solved in the embodiments of this document are not limited to those mentioned above, and other unmentioned problems will be clearly understood by those skilled in the art from the description below.

[0008] An aerosol generating device according to one embodiment may include a body comprising a chamber for storing a liquid and a liquid hole communicating with the chamber, a flavoring module detachably assembled to the body, and a cap coupled to the flavoring module and having an atomizing space inside. In one embodiment, the flavoring module may include a liquid channel for transferring the liquid from the liquid hole to the atomizing space, and a flavoring substance provided inside the liquid channel and in contact with the liquid passing through the liquid channel to add flavor.

[0009] According to one embodiment of the present document, an aerosol generating device allows a liquid to pass through a flavoring module to add flavor. Since the user of the aerosol generating device can easily and simply operate or replace the flavoring module according to their preference, the aerosol generating device can provide the user with a variety of user experiences and improve the usability of the aerosol generating device.

[0010] Alternatively, an aerosol generating device according to one embodiment can reduce or prevent leakage of liquid from the chamber.

[0011] However, the effects of the aerosol generating device according to one embodiment are not limited to those mentioned above, and other unmentioned effects will be clearly understood by a person skilled in the art from the description below.

[0032] FIG. 1 is a block diagram of an aerosol generating device (1) according to one embodiment.

[0033] According to one embodiment, the aerosol generating device (1) may include a power supply (11), a control unit (12), a sensor unit (13), an output unit (14), an input unit (15), a communication unit (16), a memory (17), and / or a heater (18, 24). However, it will be understood by those skilled in the art related to this embodiment that, depending on the design of the aerosol generating device (1), some of the components shown in FIG. 1 may be omitted or new components may be added.

[0034] According to one embodiment, the sensor unit (13) 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 (12). For example, the sensor unit (13) may include a temperature sensor, a puff sensor, an insertion detection sensor, a reuse detection sensor, an overly moist detection sensor, a cigarette identification sensor, a cartridge detection sensor, a cap detection sensor, and / or a motion detection sensor. Meanwhile, the sensor unit (13) may further include various sensors, such as a liquid residue sensor for detecting the liquid residue in the cartridge and a water immersion sensor for detecting the water immersion of the aerosol generating device (1).

[0035] According to one embodiment, a temperature sensor can detect the temperature at which the heater (18, 24) is heated. The aerosol generating device (1) may include a separate temperature sensor that detects the temperature of the heater (18, 24), or the heater (18, 24) itself may perform the role of a temperature sensor. For example, the temperature sensor may be used to measure the impedance of the heater (18). The impedance of the heater (18) may be correlated with the temperature of the heater (18). The temperature sensor may measure the current and / or voltage applied to the heater (18) (or induction coil). Based on the measured current and / or voltage, the impedance of the heater (18) may be calculated. The control unit (12) may estimate the temperature of the heater (18) based on the calculated impedance.

[0036] For example, the temperature sensor may include a resistive element (e.g., a thermistor) whose resistance value changes in response to a temperature change of the heater (18, 24). The temperature sensor may output a signal corresponding to the resistance value of the resistive element, and the control unit (12) may detect the temperature and / or temperature change of the heater (18, 24) based on the signal corresponding to the resistance value.

[0037] As another example, the temperature sensor may include a sensor that detects the resistance value of the heater (18, 24). The temperature sensor may output a signal corresponding to the resistance value of the heater (18, 24), and the control unit (12) may detect the temperature and / or temperature change of the heater (18, 24) based on the signal corresponding to the resistance value.

[0038] According to one embodiment, a temperature sensor can detect the temperature of a power source (11). The temperature sensor may be positioned adjacent to the power source (11). For example, the temperature sensor may be attached to one side of the power source (11) (e.g., a battery) and / or mounted on one side of a printed circuit board. For example, the aerosol generating device (1) may include a protection circuit module (PCM), and the temperature sensor may be positioned adjacent to the power source (11) together with the protection circuit module.

[0039] According to one embodiment, the temperature sensor may be placed inside the housing (not shown) of the aerosol generating device (1) to detect the temperature inside the housing (not shown).

[0040] According to one embodiment, the puff sensor can detect the user's puff.

[0041] For example, the puff sensor may include a pressure sensor. The pressure sensor may output a signal corresponding to the internal pressure of the aerosol generating device (1), and the control unit (12) may detect the user's puff based on the signal corresponding to the internal pressure. Here, the internal pressure of the aerosol generating device (1) may correspond to the pressure of the airflow path through which the gas flows. The puff sensor may be positioned in the aerosol generating device (1) in correspondence with the airflow path through which the gas flows.

[0042] As another example, the puff sensor may include a temperature sensor. When a user's puff occurs, a temporary temperature drop may occur in the airflow path, the space where the aerosol generating article is inserted (hereinafter, the insertion space), the heater (18, 24), etc. The control unit (12) can detect the user's puff based on a signal corresponding to the temperature of the airflow path, etc. output from the temperature sensor.

[0043] As another example, the puff sensor may include both a pressure sensor and a temperature sensor. In this case, the temperature sensor may measure the temperature used to correct the internal pressure measured by the pressure sensor. As an example, the puff sensor may correct a signal corresponding to the internal pressure based on the temperature measured by the temperature sensor and output the corrected signal. As another example, the puff sensor may output a signal corresponding to the temperature measured by the temperature sensor and a signal corresponding to the internal pressure measured by the puff sensor. In this case, the control unit (12) may receive the signals and correct the signal corresponding to the internal pressure based on the signal corresponding to the temperature.

[0044] As another example, the puff sensor may include a capacitance sensor. In the present disclosure, the capacitance sensor may be referred to as a cap sensor or a capacitive sensor. When a user's puff occurs, a temperature change and / or a flow of aerosol may occur within the insertion space of the aerosol generating article, and accordingly, the dielectric constant inside the insertion space may change. The control unit (12) can detect the user's puff based on a signal corresponding to the dielectric constant inside the insertion space, etc., output from the capacitance sensor.

[0045] The puff sensor is not limited to the examples described above and can be implemented as various sensors to detect the user's puff.

[0046] According to one embodiment, the insertion detection sensor can detect the insertion and / or removal of an aerosol-generating article. The insertion detection sensor may be installed around the insertion space. Additionally, the insertion detection sensor may include any combination of the examples described above.

[0047] For example, the insertion detection sensor may include a capacitance sensor. The capacitance sensor may include at least one conductor, and the at least one conductor may be disposed adjacent to the insertion space. When an aerosol-generating article is inserted into or removed from the insertion space, the dielectric constant around the conductor may change. The control unit (12) may detect the insertion and / or removal of the aerosol-generating article based on a signal corresponding to the dielectric constant inside the insertion space, etc., output from the capacitance sensor.

[0048] As another example, the insertion detection sensor may include an inductive sensor. The inductive sensor may include at least one coil, and said at least one coil may be positioned adjacent to the insertion space. If the aerosol generating article (e.g., a wrapper of the aerosol generating article) includes a conductor, when the aerosol generating article is inserted into the insertion space or removed from the insertion space, a change in the magnetic field may occur around the coil through which the current flows. The control unit (12) may detect the insertion and / or removal of the aerosol generating article including the conductor based on the characteristics of the current output from or detected by the inductive sensor (e.g., frequency of alternating current, current value, voltage value, inductance value, impedance value, etc.). Alternatively, a susceptor (SUS), etc., may be included in the aerosol generating article (e.g., the medium part of the aerosol generating article). In this case as well, a change in the magnetic field around the coil may occur based on the insertion or removal of a susceptor, etc., within the insertion space, and the control unit (12) may detect the insertion and / or removal of an aerosol-generating article based on the characteristics of the current of the inductive sensor.

[0049] The insertion detection sensor is not limited to the examples described above and may be implemented as various sensors (e.g., proximity sensors, etc.) for detecting the insertion and / or removal of an aerosol-generating article. Additionally, the insertion detection sensor may include any combination of the examples described above. According to one embodiment, the insertion detection sensor may include a switch, etc., for detecting pressure caused by an aerosol-generating article.

[0050] According to one embodiment, a reuse detection sensor can detect whether an aerosol-generating article is reused. For example, the reuse detection sensor may be a color sensor for detecting the color of the aerosol-generating article. When the aerosol-generating article is used by a user, a change in color may occur in a part of the wrapper covering the outside of the aerosol-generating article due to the generated aerosol or heating. The color sensor may output a signal corresponding to an optical characteristic (e.g., wavelength of light) corresponding to the color of the wrapper based on light reflected from the wrapper. When the control unit (12) detects a change in color in a part of the wrapper, it may determine that the aerosol-generating article inserted into the insertion space has already been used.

[0051] According to one embodiment, the over-humidity detection sensor can detect whether the aerosol generating article is in an over-humid state. For example, the over-humidity detection sensor may include a capacitance sensor. The capacitance sensor may include at least one conductor disposed adjacent to an insertion space. The control unit (12) can detect whether the aerosol generating article is in an over-humid state based on the level of a signal corresponding to the dielectric constant, etc., output from the capacitance sensor. For example, the control unit (12) can determine the level range in which the level of the signal is included based on a look-up table, and determine the amount of moisture for the aerosol generating article based on the confirmed level range.

[0052] According to one embodiment, the cigarette identification sensor can detect whether an aerosol-generating article is genuine or / or detect the type of aerosol-generating article.

[0053] For example, a cigarette identification sensor may include a light sensor for detecting an identification material (or identification mark) located on the outer surface (e.g., wrapper) of an aerosol-generating article. The light sensor may irradiate light toward the identification material (or identification mark) of the aerosol-generating article and detect whether the aerosol-generating article is genuine and / or of a specific type based on the reflected light. For example, the identification material may include a material that emits light of a specific wavelength band based on the irradiated light. The control unit (12) may detect whether the aerosol-generating article is genuine and / or of a specific type based on the range of the wavelengths.

[0054] As another example, the cigarette identification sensor may include a capacitance sensor. The dielectric constant inside the insertion space may vary depending on the type of aerosol-generating item inserted into the insertion space. The control unit (12) can detect whether the aerosol-generating item is genuine and / or of the type based on a signal corresponding to the dielectric constant inside the insertion space, etc., output from the capacitance sensor.

[0055] As another example, the cigarette identification sensor may include an inductive sensor. If a conductor is included in the wrapper and / or interior (e.g., the medium) of the aerosol generating article inserted into the insertion space, the characteristics of the current detected by the inductive sensor when the aerosol generating article is inserted into the insertion space (e.g., frequency of alternating current, current value, voltage value, inductance value, impedance value, etc.) may differ depending on the type of aerosol generating article inserted into the insertion space. The control unit (12) can detect whether the inserted aerosol generating article is genuine and / or of the type based on the characteristics of the current output from or detected by the inductive sensor.

[0056] The cigarette identification sensor is not limited to the examples described above and may be implemented as various sensors for detecting whether an aerosol-generating article is genuine or / or for detecting the type of an aerosol-generating article. Additionally, the cigarette identification sensor may include any combination of the examples described above.

[0057] According to one embodiment, the cartridge detection sensor can detect the mounting and / or removal of a cartridge. For example, the cartridge detection sensor may include an inductive sensor, a capacitive sensor, a resistive sensor, a Hall sensor (hall IC), and / or an optical sensor.

[0058] According to one embodiment, a cap detection sensor can detect the mounting and / or removal of a cap. For example, the cap detection sensor may include an inductive sensor, a capacitive sensor, a resistive sensor, a contact sensor, a Hall sensor (hall IC), and / or an optical sensor. The cap may include a structure that covers at least a portion of a cartridge mounted or inserted into the aerosol generating device (1), or covers at least a portion of the housing of the aerosol generating device (1). The cap detection sensor may output a signal corresponding to the mounting or removal when the cap is mounted on the housing or removed from the housing, and the control unit (12) may detect the mounting or removal of the cap based on the signal corresponding to the mounting or removal.

[0059] According to one embodiment, the motion detection sensor can detect the movement of the aerosol generating device (1). The motion detection sensor may be implemented as at least one of an accelerometer or a gyro sensor.

[0060] According to one embodiment, the sensor unit (13) may further include at least one of a humidity sensor, an atmospheric pressure sensor, a geomagnetic sensor, a position sensor (Global Positioning System, GPS), or a proximity sensor in addition to the aforementioned sensors. Since the function of each sensor can be intuitively inferred by a person skilled in the art from its name, a detailed description may be omitted.

[0061] According to one embodiment, the output unit (14) may output information regarding the state of the aerosol generating device (1). The output unit (14) may include a display, a haptic unit and / or an acoustic output unit, but is not limited thereto. For example, information regarding the aerosol generating device (1) may include the charging / discharging state of the power supply (11) of the aerosol generating device (1), the preheating state of the heater (18, 24), the insertion / removal state of the aerosol generating article and / or cartridge, the mounting and / or removal state of the cap, or a state in which the use of the aerosol generating device (1) is restricted (e.g., detection of an abnormal article). The display may visually provide information regarding the state of the aerosol generating device (1) to the user. For example, the display may include an LED (light emitting diode) light-emitting element, a Liquid Crystal Display (LCD), an Organic Light Emitting Diodes (OLED), etc. The display can also be used as an input unit (15) if it includes a touch pad. The haptic unit can provide information about the state of the aerosol generating device (1) to the user tactilely. For example, the haptic unit may include a vibration motor, a piezoelectric element, an electric stimulation device, etc. The acoustic output unit can provide information about the aerosol generating device (1) to the user audibly. For example, the acoustic output unit can convert an electrical signal into an acoustic signal and output it externally.

The power source (11) can supply power so that the heater (18, 24) can be heated. Additionally, the power source (11) may supply power required for the operation of other components included in the aerosol generating device (1), such as the control unit (12), sensor unit (13), output unit (14), input unit (15), communication unit (16), memory (17), etc. The power source (11) may be a rechargeable battery or a disposable battery.

The removable battery may be mounted in a battery housing provided within the aerosol generating device (1) or removed from the battery housing. The removable battery may also be charged via wired and / or wireless connections.

[0063] According to one embodiment, the heater (18, 24) can heat the aerosol generating article and / or the medium and / or aerosol generating material within the cartridge by receiving power from the power source (11). The aerosol generating device (1) may include a heater (18) for heating the aerosol generating article and / or a cartridge heater (24) for heating the cartridge (i.e., solid and / or liquid medium).

[0064] According to one embodiment, the heater (18, 24) may be an electric resistive heater.

[0065] According to one embodiment, the heater (18, 24) may be an induction heating type heater. For example, the induction heating type heater may include a susceptor that generates heat by a magnetic field. A magnetic field may be generated from the induction coil by an alternating current flowing through the induction coil. The generated magnetic field penetrates the heater, and eddy currents may be generated in the susceptor. The susceptor may be heated based on the generation of eddy currents. According to one embodiment, the susceptor may be contained within an aerosol-generating article (e.g., a medium). In this case as well, the susceptor contained within the aerosol-generating article may be heated by the induction coil.

[0066] The heater (18, 24) is not limited to the examples described above and may include or be replaced with various heating methods, structures, components, etc. for heating an aerosol generating article and / or cartridge.

[0070] According to one embodiment, the control unit (12) can control the overall operation of the aerosol generating device (1). For example, the control unit (12) may include at least one processor. The control unit (12) may be implemented as an array of logic gates, or as a combination of a general-purpose MCU (micro controller unit) (or microprocessor) and a memory storing a program that can be executed on such MCU. Furthermore, it will be understood by those skilled in the art to which this embodiment belongs that it may be implemented in other forms of hardware.

[0071] According to one embodiment, the control unit (12) can control the temperature of the heater (18, 24) by controlling the supply of power from the power source (11) to the heater (18, 24). The control unit (12) can control the temperature of the heater (18, 24) and / or the power supplied to the heater (18, 24) based on the temperature of the heater (18, 24) detected using a temperature sensor (e.g., sensor unit (13)). The control unit (12) can control the temperature of the heater (18, 24) and / or the power supplied to the heater (18, 24) based on a temperature profile and / or power profile stored in the memory (17).

[0072] According to one embodiment, the control unit (12) can control the power (e.g., voltage and / or current) supplied to the heater (18, 24) by controlling a power conversion circuit (not shown) electrically connected to the heater (18, 24) and the power source (11). For example, the power conversion circuit may include a DC / DC converter (e.g., buck converter, buck-boost converter, boost converter, Zener diode, etc.) that converts power to be supplied to the heater (18, 24), and a DC / AC converter (e.g., inverter) that converts power to be supplied to an induction coil (not shown). The DC / AC converter may be implemented as a full-bridge circuit or a half-bridge circuit including a plurality of switching elements. For example, the power conversion circuit may include at least one switching element, such as a bipolar junction transistor (BJT) or a field effect transistor (FET).

[0073] According to one embodiment, the control unit (12) can adjust the frequency and / or duty ratio of a current pulse input to at least one switching element of a power conversion circuit (not shown) to adjust the current and / or voltage supplied to the heater (18, 24). The duty ratio for the on / off operation of the switching element may correspond to the ratio of the output voltage of the power conversion circuit to the output voltage of the power supply (11).

[0074] According to one embodiment, the control unit (12) can control the power supplied to the heater (18, 24) by using at least one of a Pulse Width Modulation (PWM) method and a Proportional-Integral-Differential (PID) method. For example, the control unit (12) can control the supply of a current pulse having a predetermined frequency and duty ratio to the heater (18, 24) by using the PWM method. The control unit (12) can control the power supplied to the heater (18, 24) by adjusting the frequency and duty ratio of the current pulse. For example, the control unit (12) can determine a target temperature that is the target of the control based on a temperature profile. The control unit (12) can control the power supplied to the heater (18, 24) by using a PID method, which is a feedback control method using the difference value between the temperature of the heater (18, 24) and the target temperature, the value obtained by integrating the difference value over time, and the value obtained by differentiating the difference value over time.

[0075] According to one embodiment, the control unit (12) can determine a target power that is the target of control based on a power profile. The control unit (12) may also control the power supplied to the heater (18, 24) to correspond to a preset target power over time.

[0076] According to one embodiment, the control unit (12) can detect the user's puff by detecting the power supplied to the heater (18, 24). More specifically, the control unit (12) can control the power supplied to the heater (18, 24) using a PID method. When the user's puff occurs, a temporary temperature drop may occur in the space where the aerosol generating item is inserted (hereinafter, insertion space), the heater (18, 24), etc. Accordingly, a change may occur in the power (or current) supplied to the heater (18, 24) during the power control of the PID method. The control unit (12) can detect the user's puff based on the change in the controlled power.

[0077] According to one embodiment, the control unit (12) can prevent the heater (18, 24) from overheating. For example, the control unit (12) can control the operation of the power conversion circuit to reduce the amount of power supplied to the heater (18, 24) or stop the power supply to the heater (18, 24) based on the fact that the temperature of the heater (18, 24) exceeds a preset limit temperature.

[0078] According to one embodiment, the control unit (12) can control the charging and discharging of the power source (11). For example, the control unit (12) can check the temperature of the power source (11) using a temperature sensor (e.g., sensor unit (13)). The control unit (12) can cut off the charging of the power source (11) if the temperature of the power source (11) is above a first limit temperature. The control unit (12) can stop the use (e.g., discharge) of the power stored in the power source (11) if the temperature of the power source (11) is above a second limit temperature. The control unit (12) can calculate the remaining capacity of the power stored in the power source (11). For example, the control unit (12) can calculate the remaining capacity of the power source (11) based on the voltage and / or current sensing values ​​of the power source (11).

[0079] According to one embodiment, the control unit (12) can control the power supply to the heater (18, 24) based on the result detected by the sensor unit (13).

[0080] According to one embodiment, the control unit (12) can control the power supply to the heater (18, 24) based on the insertion and / or removal of an aerosol-generating article into the insertion space. For example, the control unit (12) can control the power supply to the heater (18, 24) when it is determined that an aerosol-generating article has been inserted into the insertion space using an insertion detection sensor (e.g., sensor unit (13)). The control unit (12) can cut off the power supply to the heater (18, 24) when it is determined that an aerosol-generating article has been removed from the insertion space using an insertion detection sensor (e.g., sensor unit (13)). The control unit (12) may also determine that an aerosol-generating article has been removed from the insertion space if the temperature of the heater (18, 24) is above a limit temperature or the temperature change slope of the heater (18, 24) is above a set slope.

[0081] According to one embodiment, the control unit (12) can control the power supply time and / or power supply amount for the heater (18, 24) based on the state of the aerosol generating article. For example, the control unit (12) can increase the power supply time (e.g., preheating time) for the heater (18, 24) if it is determined that the aerosol generating article is in an over-humid state using an over-humidity detection sensor (e.g., sensor unit (13)).

[0082] According to one embodiment, the control unit (12) can control the power supply to the heater (18, 24) based on whether the aerosol-generating article is reused. For example, if the control unit (12) determines that the aerosol-generating article has been used, it can cut off the power supply to the heater (18, 24).

[0083] According to one embodiment, the control unit (12) can control the power supply to the heater (18, 24) based on whether the cartridge is coupled and / or removed. For example, the control unit (12) can use a cartridge detection sensor (e.g., sensor unit (13)) to determine that the cartridge is separated, and if it is determined that the cartridge is separated, the power supply to the heater (18, 24) is stopped or the power is not supplied to the heater (18, 24).

[0084] According to one embodiment, the control unit (12) can control the power supply to the heater (18, 24) based on whether the aerosol generating material of the cartridge is depleted. For example, the control unit (12) may determine that the aerosol generating material of the cartridge is depleted if it determines that the temperature of the heater (18, 24) exceeds a limit temperature while preheating the heater (18, 24) (i.e., during the preheating period). If it is determined that the aerosol generating material of the cartridge is depleted, the control unit (12) may cut off the power supply to the heater (18, 24).

[0085] According to one embodiment, the control unit (12) can control the power supply to the heater (18, 24) based on whether the cartridge is usable. For example, the control unit (12) may determine that the cartridge is unusable if, based on data stored in the memory (17), the current number of puffs is determined to be greater than or equal to the maximum number of puffs set in the cartridge. Alternatively, the control unit (12) may determine that the cartridge is unusable if the total time the heater (18, 24) is heated is greater than or equal to the preset maximum time, or if the total amount of power supplied to the heater (18, 24) is greater than or equal to the preset maximum amount of power. In this case, the control unit (12) may stop the power supply to the heater (18, 24) or control that power is not supplied to the heater (18, 24).

[0086] According to one embodiment, the control unit (12) can control the power supply to the heater (18, 24) based on the user's puff. For example, the control unit (12) can determine whether a puff has occurred and / or the intensity of the puff using a puff sensor (e.g., sensor unit (13)). The control unit (12) can cut off the power supply to the heater (18, 24) when the number of puffs reaches a preset maximum number of puffs or / or when no puff is detected for more than a preset time. The control unit (12) may also control the power supply to the heater (18, 24) when a puff is detected.

[0087] According to one embodiment, the control unit (12) can control the power supply to the heater (18, 24) based on whether the aerosol generating item (or cartridge) is genuine and / or of a specific type. For example, the control unit (12) can detect whether the aerosol generating item is genuine and / or of a specific type using a cigarette identification sensor (e.g., sensor unit (13)). For example, if the control unit (12) detects that the aerosol generating item (or cartridge) is counterfeit, it can cut off the power supply to the heater (18, 24). If the control unit (12) detects that the aerosol generating item (or cartridge) is genuine, it can control (e.g., start) the power supply to the heater (18, 24). For another example, the control unit (12) can control the power supply to the heater (18, 24) differently depending on the specific type of the aerosol generating item (or cartridge). More specifically, the control unit (12) can control the temperature and / or power of the heater (18, 24) based on a first temperature profile (or a first power profile) when the aerosol generating article (or cartridge) is detected to be a first aerosol generating article (or a first cartridge), and control the temperature and / or power of the heater (18, 24) based on a second temperature profile (or a second power profile) when the aerosol generating article (or a second cartridge) is detected to be a second aerosol generating article (or a second cartridge).

[0088] According to one embodiment, the control unit (12) can control the output unit (14) based on the result detected by the sensor unit (13). For example, the control unit (12) can control the output unit (14) to provide visual, tactile, and / or auditory information that the aerosol generating device (1) will soon be terminated when the number of puffs counted using the puff sensor (e.g., sensor unit (13)) reaches a preset number. For example, the control unit (12) can also control the output unit (14) to provide visual, tactile, and / or auditory information regarding the temperature of the heater (18, 24).

[0089] According to one embodiment, the control unit (12) may store and update a history of the event that occurred in the memory (17) based on the occurrence of a predetermined event. For example, the event may include operations performed in the aerosol generating device (1), such as detection of insertion of an aerosol generating article, initiation of heating of the aerosol generating article, puff detection, puff termination, detection of overheating of the heater (18, 24), detection of overvoltage application to the heater (18, 24), termination of heating of the aerosol generating article, power on / off of the aerosol generating device (1), initiation of charging of the power source (11), detection of overcharging of the power source (11), termination of charging of the power source (11), etc. For example, the history of the event may include the time and date when the event occurred, log data corresponding to the event, etc. For example, if a predetermined event is the detection of insertion of an aerosol-generating article, the log data corresponding to the event may include data regarding the sensing value of an insertion detection sensor (e.g., sensor unit (13)). For example, if a predetermined event is the detection of overheating of a heater (18, 24), the log data corresponding to the event may include data regarding the temperature of the heater (18, 24), the voltage applied to the heater (18, 24), the current flowing through the heater (18, 24), etc.

[0090] According to one embodiment, the control unit (12) can control the communication unit (16) to form a communication link with an external device, such as a user's mobile terminal.

[0091] According to one embodiment, when the control unit (12) receives authentication data from an external device via a communication link, it may release the restriction on the use of at least one function (e.g., heating function) of the aerosol generating device (1). For example, the authentication data may include the user's birthday, a unique number representing the user, whether the user's authentication is complete, etc.

[0092] According to one embodiment, the control unit (12) can transmit data regarding the status of the aerosol generating device (1) (e.g., remaining capacity of the power supply (11), operating mode, etc.) to an external device via a communication link. The transmitted data can be output through a display of the external device, etc.

[0093] According to one embodiment, when a control unit (12) receives a location search request for an aerosol generating device (1) from an external device via a communication link, the control unit (12) can control the output unit (14) to perform an operation corresponding to the location search. For example, the control unit (12) can control the haptic unit to generate vibrations or control the display to output an object corresponding to the location search and the end of the search.

[0094] According to one embodiment, the control unit (12) can perform a firmware update when firmware data is received from an external device through a communication link.

[0095] According to one embodiment, the control unit (12) transmits data regarding the sensing value of at least one sensor unit (13) to an external server (not shown) via a communication link, and receives and stores a learning model generated by learning the sensing value through machine learning, such as deep learning, from the server. The control unit (12) can use the learning model received from the server to perform operations such as determining the user's inhalation pattern and generating a temperature profile.

[0096] Although not illustrated in FIG. 1, the aerosol generating device (1) may further include a power protection circuit. The power protection circuit may include at least one switching element and may cut off the power supply (11) in response to overcharging and / or over-discharging of the power supply (11). The aerosol generating device (1) may further include a connection interface, such as a USB (universal serial bus) interface, and may transmit and receive information or charge the power supply (11) by connecting to another external device through the connection interface.

[0097] The aerosol generating article mentioned in the present disclosure may include at least one aerosol generating rod (e.g., a medium part) and at least one filter rod. A heater (18) may be positioned to correspond to at least one aerosol generating rod and may be designed differently depending on the arrangement order and / or position of the aerosol generating rod and the filter rod. The aerosol generating rod may include at least one of nicotine, an aerosol generating material, and an additive. For example, the aerosol generating material may include glycerin (e.g., vegetable glycerin (VG)) and / or propylene glycol (PG), and may include various other materials. For example, the additive may include flavoring agents and / or organic acids, and may include various other materials. For example, the aerosol generating rod may comprise an aerosol generating substrate (e.g., a sheet) impregnated with a liquid non-tobacco material (e.g., an aerosol generating material and / or nicotine), and / or may comprise a solid tobacco material (e.g., leaf tobacco, reconstituted tobacco, etc.). The tobacco material may be included in the aerosol generating rod in various forms, such as whole tobacco, granules, or powder. According to one embodiment, the additive of the aerosol generating rod may comprise a basic material. Based on the basic material, the nicotine in the tobacco material included in the aerosol generating rod may have a basic pH (e.g., pH 7.0 or higher). In this case, freebase nicotine may be released from the aerosol generating rod even at low temperatures. According to one embodiment, the aerosol generating rod comprises two or more aerosol generating rods, and said two or more aerosol generating rods may each comprise a tobacco material and / or a non-tobacco material.Meanwhile, although not illustrated, at least one aerosol generating rod and at least one filter rod may each and / or integrally be wrapped by at least one wrapper. In the present disclosure, the aerosol generating article may be referred to as a stick.

[0098] The cartridge mentioned in the present disclosure may contain an aerosol generating material having any one of the states, such as a liquid state, a solid state, a gaseous state, or a gel state. The aerosol generating material may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing material containing a volatile tobacco flavor component, or a liquid containing a non-tobacco material. Meanwhile, the cartridge may include a chamber containing the aerosol generating material and / or a liquid delivery means impregnating (containing) the aerosol generating material. For example, the liquid delivery means may include a wick such as a cotton fiber, a ceramic fiber, a glass fiber, or a porous ceramic. The cartridge heater (24) may be included in the cartridge in a coil-shaped structure that surrounds (or winds) the liquid delivery means or in a structure that contacts one side of the liquid delivery means. Alternatively, the cartridge heater (24) may be included in an aerosol generating device (1) that is detachable from the cartridge.

[0099] FIG. 2 illustrates an aerosol generating device (1) according to one embodiment.

[0100] According to one embodiment, the aerosol generating device (1) may include a housing (10), a power source (11), a control unit (12), a sensor unit (13), and / or a heater (183, 24) (e.g., the heater (18, 24) of FIG. 1). However, it will be understood by those skilled in the art related to this embodiment that the components included in the aerosol generating device (1) are not limited to those shown in FIG. 2, and some of the components may be omitted or new configurations may be added. In the following drawings, descriptions that overlap with the drawings described above will be omitted.

[0101] According to one embodiment, the housing (10) may provide a space (hereinafter, insertion space) that is open upward so that an aerosol generating article (2) can be inserted. The insertion space may be formed by being recessed to a predetermined depth toward the interior of the housing (10) so that at least a portion of the aerosol generating article (2) can be inserted. The lower end of the aerosol generating article (2) may be inserted into the interior of the housing (10), and the upper end of the aerosol generating article (2) may protrude to the exterior of the housing (10).

[0102] Unlike what is described, the cartridge (19) may provide an insertion space for receiving an aerosol generating article (2). In this case, the insertion space may be formed by being recessed to a certain depth toward the interior of the cartridge (19) so that at least a portion of the aerosol generating article (2) can be inserted. The bottom of the aerosol generating article (2) may be inserted into the interior of the cartridge (19), and the top of the aerosol generating article (2) may protrude outside the cartridge (19). Also, in this case, the aerosol generating device (1) may not include a heater (183).

[0103] According to one embodiment, the depth of the insertion space may be greater than the length of the area containing the aerosol generating material and / or medium in the aerosol generating article (2). A user may put the top of the aerosol generating article (2) exposed to the outside into their mouth and inhale air.

[0104] According to one embodiment, the heater (183) can heat the aerosol generating article (2). The heater (183) may extend upwardly around the space (i.e., insertion space) into which the aerosol generating article (2) is inserted. For example, the heater (183) may be in the form of a tube (e.g., a cylinder) containing a hollow inside. The heater (183) may include a form that contains a hollow inside and surrounds the hollow. In this case, the heater (183) may be supported by a polyimide film. A heater (183) supported by such a film may be referred to as a film heater. The heater (183) may be positioned to surround at least a portion of the insertion space. The heater (183) may heat the outside of the aerosol generating article (2) inserted into the hollow. In the present disclosure, the heater (183) may be referred to as an external heating type heater that heats the outside of the aerosol generating article (2). Meanwhile, an insulating material may be placed on the outside of the heater (183). Through this, heat radiating outward from the heater (183) and applied to the outside of the housing (10) can be reduced.

[0105] According to one embodiment, the heater (183) may include an electric resistive heater and / or an induction heating type heater.

[0106] For example, an electric resistive heater may include an electric resistive material and may be heated as current flows through the electric resistive material. In this case, the electric resistive heater may be electrically connected to a power source (11) and may be directly heated by receiving current from the power source (11).

[0107] For example, in the case of an induction heating type heater, the aerosol generating device (1) may further include an induction coil (not shown) that surrounds at least a portion of the heater (183) (e.g., placed outside the heater to correspond to the length of at least a portion of the heater (183)). In this case, a magnetic flux concentrator, etc., may be further included outside the induction coil (not shown) to increase the efficiency of induction heating. The induction heating type heater may include a susceptor and generate heat based on a magnetic field generated from the induction coil (not shown).

[0108] According to one embodiment, the heater (183) may be a multiple heater. The multiple heater may include a first heater and a second heater and may be inserted into an aerosol generating article (2). The first heater and the second heater may be arranged side by side along the longitudinal direction. The first heater and the second heater may operate as an electric resistive heater and / or an induction heating type heater, and may be heated sequentially or simultaneously. In this case, the first heater and the second heater may be respectively placed at positions corresponding to longitudinal positions of two or more aerosol generating rods. Alternatively, the first heater and the second heater may be respectively placed at positions corresponding to longitudinal positions of a first part and a second part of a single aerosol generating rod. Meanwhile, if the heater (183) is an induction heating type heater, the aerosol generating device (1) includes a first induction coil and a second induction coil, and the first induction coil and the second induction coil may be respectively placed at positions corresponding to longitudinal positions of the first heater and the second heater. Alternatively, the first heater and the second heater may be respectively placed at positions corresponding to longitudinal positions of a first part and a second part of a single heater (183). In addition, the heater and / or induction coil may include three or more.

[0109] Unlike what is described, the aerosol generating device (1) may not include a heater (183). The aerosol generating article (2) may be heated directly or indirectly by the cartridge heater (24), or may not be heated substantially. Indirect heating may mean that the aerosol generating article (2) is heated by receiving heat contained in the aerosol as the aerosol generated by the cartridge heater (24) passes through the aerosol generating article (2). In this case, the aerosol generating device (1) may be referred to as a non-heating (or indirectly heated) aerosol generating device. The aerosol generating rod of the aerosol generating article (2) may contain additives such as basic substances. Based on these basic substances, the nicotine contained in the aerosol generating rod may have a basic pH (e.g., pH 7.0 or higher). This basic nicotine can flow into the user's mouth along with the aerosol flowing from the cartridge (19) described later into the aerosol generating article (2).

[0110] Unlike what is described, the heater (183) may include an internal heating type heater. For example, the internal heating type heater may include various heating elements such as a rod type, a tubular type heating element, a plate type heating element, or a needle type heating element. The internal heating type heater may be inserted through the bottom of the aerosol generating article (2) and may be set to heat the inside of the aerosol generating article (2).

[0111] According to one embodiment, the cartridge (19) may be detachably coupled to the housing (10). For example, a space may be formed on one side of the housing (10), and at least a portion of the cartridge (19) may be inserted into the space formed on one side of the housing (10) so that the cartridge (19) may be mounted on the housing (10). Alternatively, the cartridge (19) may be integrally formed with the housing (10).

[0112] According to one embodiment, the aerosol generating device (1) and / or cartridge (19) may be provided with an airflow channel through which air flows. For example, the housing (10) may include a structure that allows air from the outside to flow into the interior of the housing (10) when the cartridge (19) is inserted. The incoming air may pass through the cartridge (19) and flow into the insertion space through the airflow channel (CN) and into the user's oral cavity. The airflow channel (CN) may include various structures to reduce residual droplets or to facilitate airflow.

[0113] In FIG. 2, the cartridge (19) is shown positioned on the side of the aerosol generating article (2) and the airflow channel (CN) is shown formed from the side of the aerosol generating article (2) to the bottom (i.e., upstream side) of the aerosol generating article (2), but the positions of the cartridge (19) and the airflow channel (CN) are not limited thereto. For example, the cartridge (19) may be positioned adjacent to the bottom (i.e., upstream side) of the aerosol generating article (2), in which case the airflow channel (CN) may be formed in a substantially straight shape to connect the cartridge (19) and the bottom (i.e., upstream side) of the aerosol generating article (2).

[0114] According to one embodiment, the cartridge (19) may include a chamber (C0) containing an aerosol generating material, a cartridge heater (24), and / or a liquid delivery means (25) impregnating (containing) the aerosol generating material. The liquid delivery means (25) may impregnate the aerosol generating material supplied from the chamber (C0). For example, the liquid delivery means (25) may include a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0115] According to one embodiment, the cartridge heater (24) can heat an aerosol generating material contained in the cartridge (19). For example, the cartridge heater (24) may include an electric resistive heater and / or an induction heating heater.

[0116] For example, an electric resistive heater may include an electric resistive material and may be heated as current flows through the electric resistive material. For another example, in the case of an induction heating type heater, the aerosol generating device (1) may further include an induction coil (not shown) around the induction heating type heater. The induction heating type heater may include a susceptor and may generate heat based on a magnetic field generated from the induction coil (not shown). The cartridge heater (24) may be formed in a coil shape that surrounds (or wraps around) the liquid delivery means (25) and / or in a shape that contacts one side of the liquid delivery means (25) (e.g., a pattern shape).

[0117] Unlike what is described, the cartridge heater (24) may be included in the aerosol generating device (1). For example, the cartridge heater (24) may be included inside the housing (10). In this case, the cartridge (19) and the cartridge heater (24) may be separated by removing the cartridge (19).

[0118] According to one embodiment, an aerosol may be generated based on the heat generated by the cartridge heater (24). For example, as the aerosol generating material impregnated in the liquid delivery means (25) is heated by the cartridge heater (24), vapor may be generated from the aerosol generating material, and as the generated vapor is mixed with the outside air introduced into the cartridge (19), an aerosol may be generated. The aerosol generated by the cartridge heater (24) may be introduced into the aerosol generating article (2) through the airflow channel (CN). While the aerosol passes through the aerosol generating article (2), tobacco or flavoring material may be added to the aerosol, and the aerosol with added tobacco or flavoring material may be inhaled into the user's mouth through one end of the aerosol generating article (2).

[0119] FIG. 3 illustrates an aerosol generating device according to one embodiment.

[0120] FIG. 3 illustrates an aerosol generating device (1) according to one embodiment. According to one embodiment, the aerosol generating device (1) may include a housing (10), a power source (11), a control unit (12), and / or a sensor unit (13). However, it will be understood by those skilled in the art related to this embodiment that the components included in the aerosol generating device (1) are not limited to those shown in FIG. 1, and that some of the components may be omitted or new components may be added. In the following drawings, descriptions that overlap with FIG. 1 will be omitted.

[0121] According to one embodiment, the housing (10) may include a structure for inserting or mounting a cartridge (19) on one side. In this case, the cartridge (19) may be detachably coupled to the housing (10).

[0122] Although not illustrated, the housing (10) and / or cartridge (19) may include a mouthpiece. The user may place the mouthpiece in their mouth and inhale the aerosol.

[0123] According to one embodiment, the cartridge (19) may include a chamber (C0) containing an aerosol generating material. The chamber (C0) may contain an aerosol generating material having any one of the following states: liquid state, solid state, gaseous state, or gel state. The aerosol generating material may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing material containing a volatile tobacco flavor component, or a liquid containing a non-tobacco material.

[0124] According to one embodiment, a liquid delivery means (25) impregnated (containing) an aerosol generating material may be included in a cartridge (19). For example, the liquid delivery means (25) may impregnate an aerosol generating material supplied from a chamber (C0). Here, the liquid delivery means (25) may include a wick such as cotton fibers, ceramic fibers, glass fibers, or porous ceramics. Although not illustrated, the aerosol generating device (1) may further include a liquid delivery means. In this case, at least a portion of the first liquid delivery means of the cartridge (19) and at least a portion of the second liquid delivery means of the aerosol generating device (1) may be formed to be in contact. In this case, the first liquid delivery means and the second liquid delivery means may be implemented in different forms. For example, the first liquid delivery means may include cotton fibers, and the second liquid delivery means may include porous ceramics. Alternatively, the cartridge (19) may not include a liquid delivery means (25), and the aerosol generating material of the cartridge (19) may be transferred to the liquid delivery means (25) of the aerosol generating device (1).

[0125] According to one embodiment, the housing (10) and / or cartridge (19) may be provided with an airflow channel through which air flows.

[0126] For example, the housing (10) may include a structure that allows outside air to flow into the interior of the housing (10) while the cartridge (19) is attached. As an example, an air inlet through which outside air can flow into the interior of the housing (10) may be formed on one side of the aerosol housing (10). The air inlet may also be formed on the bottom surface of the housing (10). Outside air introduced into the interior of the housing (10) through the air inlet may pass through the cartridge (19) and then flow in a direction toward the user's oral cavity through the airflow channel (CN). Outside air introduced through this air inlet hole may pass through the cartridge (19) and flow toward the user's oral cavity through the airflow channel (CN).

[0127] For example, an airflow channel (CN) may be included in the cartridge (19). The airflow channel (CN) may connect the outside of the housing (10) and / or the cartridge (19) to a chamber (e.g., atomizing chamber) in which the cartridge heater (24) or liquid delivery means (25) is placed. More specifically, one end of the airflow channel (CN) may open to the chamber (e.g., atomizing chamber) in which the cartridge heater (24) or liquid delivery means (25) is placed, and the other end may be in communication with the mouthpiece. The airflow channel (CN) may extend along the longitudinal direction of the cartridge (19) from one side of the chamber (C0) of the cartridge (19). The airflow channel (CN) may also extend along the longitudinal direction of the cartridge (19) by penetrating the chamber (C0) of the cartridge (19). The airflow channel (CN) may also be in communication with a mouthpiece separately provided in the housing (10).

[0128] According to one embodiment, the cartridge heater (24) can heat the aerosol generating material contained in the cartridge (19). For example, the cartridge heater (24) may include an electric resistive heater and / or an induction heating heater. In one example, the electric resistive heater may include an electric resistive material and may be heated as current flows through the electric resistive material. In another example, in the case of an induction heating heater, the aerosol generating device (1) may further include an induction coil (not shown) around the induction heating heater. The induction heating heater may include a susceptor and may generate heat based on a magnetic field generated from the induction coil (not shown). The cartridge heater (24) may be formed in a coil shape that surrounds (or wraps around) the liquid delivery means (25) contained in the cartridge (19) and / or the aerosol generating device (1) and / or in a shape that contacts one side of the liquid delivery means (25) (e.g., a pattern shape).

[0129] According to one embodiment, the cartridge heater (24) may be included in the cartridge (19). If the cartridge (19) is in a form that is separable from the housing (10), the cartridge heater (24) may be separable from the aerosol generating device (1) together with the cartridge (19). Unlike what is illustrated, the cartridge heater (24) may be included in the aerosol generating device (1). For example, the cartridge heater (24) may be included inside the housing (10). Meanwhile, the cartridge heater (24) may be included in a form that is separable from the housing (10) separately (i.e., independently) from the cartridge (19). In other words, the cartridge heater (24) may or may not be separated from the housing (10) regardless of whether the cartridge (19) is separated.

[0130] According to one embodiment, an aerosol may be generated based on the heat generated by the cartridge heater (24). As the liquid delivery means (25) is heated by the cartridge heater (24), an aerosol may be generated. For example, as the aerosol generating material impregnated in the liquid delivery means (25) is heated by the cartridge heater (24), vapor may be generated from the aerosol generating material, and as the generated vapor is mixed with the outside air introduced into the cartridge (19), an aerosol may be generated. The aerosol generated by the cartridge heater (24) may be inhaled into the user's mouth through the airflow channel (CN).

[0131] According to one embodiment, the cartridge (19) may be formed integrally with the aerosol generating device (1) (e.g., housing (10)). The cartridge (19) may be formed so that it cannot be separated from the aerosol generating device (1) by a user. Even in this case, the cartridge (19) and / or the aerosol generating device (1) may include at least one liquid delivery means (25), and an aerosol is generated based on a cartridge heater (24) included in the aerosol generating device (1) or the cartridge (19) heating the liquid delivery means (25), and the generated aerosol may be inhaled into the user's mouth through an airflow channel (CN).

[0132] FIG. 4a is a perspective view of an aerosol generating device (100) according to one embodiment, FIG. 4b is a cross-sectional view of a second housing part (150) according to one embodiment, and FIG. 4c is an exploded perspective view of the second housing part (150) according to one embodiment. Specifically, FIG. 4b is a cross-sectional view of the second housing part (150) viewed in the AA' direction of FIG. 4a.

[0133] Referring to FIGS. 4a, 4b, and 4c, an aerosol generating device (100) (e.g., the aerosol generating device (1) of FIGS. 1, 2, and 3) may include a housing structure (105) (e.g., the housing (10) of FIGS. 2 and 3).

[0134] In the following description, details that overlap with the above-described content are omitted. It is understood that in the aerosol generating device (100), some components and structures may be replaced, added, or omitted to the extent that they are easily understood by a person skilled in the art with reference to the drawings and description below. Furthermore, at least one component or feature of the previously described embodiments may be combined in the aerosol generating device (100) unless it is not technically obvious.

[0135] In one embodiment, the housing structure (105) may form the exterior of the aerosol generating device (100). Alternatively, the housing structure (105) may accommodate other components of the aerosol generating device (100). Alternatively, the housing structure (105) may be the housing, body, or main body of the aerosol generating device (100).

[0136] In one embodiment, the housing structure (105) may include at least some of a first housing portion (110), a second housing portion (150), and a cover (115). The second housing portion (150) may be detachably connected to the first housing portion (110). The cover (115) may surround, protect, or support the second housing portion (150).

[0137] For example, the first housing portion (110) may be a main body or a device. The first housing portion (110) may accommodate elements for driving the aerosol generating device (100). For example, the first housing portion (110) may be provided with at least one of a power supply (e.g., power supply (11) of FIGS. 1, 2 and 3), a processor (e.g., control unit (12) of FIGS. 1, 2 and 3), and a sensor unit (e.g., sensor unit (13) of FIGS. 1, 2 and 3).

[0138] For example, the second housing portion (150) may be a replaceable element or cartridge (e.g., cartridge (19) of FIG. 2 and FIG. 3). For example, the second housing portion (150) may be provided with at least one of a chamber (152) (e.g., chamber (C0) of FIG. 2 and FIG. 3) and an atomizing space (172).

[0139] In one embodiment, the housing structure (105) may include an intake port (113). The intake port (113) may be an opening through which an aerosol generated by the aerosol generating device (100) is discharged. Alternatively, the intake port (113) may be an opening for inserting an aerosol generating article (e.g., the aerosol generating article (2) of FIG. 2) from outside the aerosol generating device (100).

[0140] In one embodiment, the housing structure (105) may include a cavity (114). The cavity (114) may be a channel for the aerosol generated in the aerosol generating device (100) to be discharged outside the aerosol generating device (100). Alternatively, an aerosol generating article may be inserted into the cavity (114) from outside the aerosol generating device (100). For example, the cavity (114) may be an elongated cavity, a joining area, an insertion area, or a heating area into which the aerosol generating article is inserted.

[0141] In one embodiment, the housing structure (105) may include an aerosol channel (118). The aerosol channel (118) may be connected from the second housing portion (150) to the cavity (114). The aerosol generated in the second housing portion (150) may be delivered to the cavity (114) through the aerosol channel (118).

[0142] In one embodiment, the second housing portion (150) may include at least one of a body (151), a directional module (160), an O-ring (157), and a cap (170).

[0143] In one embodiment, the body (151) may include a chamber (152) and a liquid hole (153). A liquid (L) may be stored in the chamber (152). The liquid hole (153) may be connected to the chamber (152). The liquid (L) stored in the chamber (152) may be an aerosol generating material or a raw material. For example, the liquid (L) may be a liquid containing a tobacco-containing material containing a volatile tobacco flavor component, or a liquid containing a non-tobacco material.

[0144] In one embodiment, the cap (170) may include an atomizing space (172) and a connecting part (173). The atomizing space (172) may receive liquid (L) that has passed through the flavoring module (160). In the atomizing space (172), the liquid (L) may be aerosolized. The generated aerosol may be delivered to an aerosol channel (118) through the connecting part (173). Although not shown in the drawings, at least one of a heater (e.g., heater (18, 24) of FIG. 1, heater (24, 183) of FIG. 2, and heater (24) of FIG. 3), a wick (e.g., liquid delivery means (25) of FIG. 3), a vibrator, and a heat transfer element may be disposed inside the atomizing space (172).

[0145] In one embodiment, an O-ring (157) may be provided between the directional module (160) and the body (151). The O-ring (157) may seal the joint portion of the directional module (160) and the body (151). Alternatively, the O-ring (157) may enhance the bonding strength between the directional module (160) and the body (151).

[0146] In one embodiment, the flavoring module (160) may be detachably assembled to the body (151). The flavoring module (160) may include a liquid channel (161) and a flavoring substance (165). The liquid channel (161) may receive liquid (L) from the liquid hole (153) and may transfer the liquid (L) to the atomizing space (172). The liquid channel (161) may refer to a space or cavity through which the liquid (L) passes, and may be, for example, a liquid transfer area or a liquid transport area.

[0147] In one embodiment, the liquid channel (161) may include an inlet (162) communicating with the liquid hole (153) and an outlet (163) communicating with the atomizing space (172). In one embodiment, the outlet (163) may have a relatively larger area than the inlet (162). Accordingly, the liquid (L) introduced into the inlet (162) passes through the liquid channel (161), adding flavor, and can be smoothly discharged through the outlet (163). Additionally, as shown in the drawing, in the liquid channel (161) where the width (e.g., length along the X-axis or Y-axis) is relatively larger than the height (e.g., length along the Z-axis), a larger area of ​​the outlet (163) may be advantageous for the discharge of the liquid.

[0148] In one embodiment, a flavoring substance (165) may be provided inside a liquid channel (161). The flavoring substance (165) may come into contact with a liquid (L) passing through the liquid channel (161) to add flavor to the liquid (L). For example, the liquid (L) stored in the chamber (152) may be odorless, and the liquid (L) may pass through a flavoring module (160) to add flavor. Alternatively, the flavor of the liquid (L) may change or become richer as it passes through the flavoring module (160).

[0149] In one embodiment of the present document, the flavoring module (160) adds flavor to the liquid (L), thereby allowing the aerosol generating device (100) to provide usability tailored to the user's preferences, and also allowing the aerosol generating device (100) to provide the user with various usage experiences.

[0150] For example, the user can add flavor to the aerosol according to their preference through the flavoring module (160). Additionally, the user can easily replace or refill the flavoring module (160) by selecting a flavor.

[0151] In one embodiment, the flavoring material (165) may consist of a porous material through which a liquid (L) passes and a liquid fragrance impregnated in the porous material. For example, the flavoring material (165) may consist of a sponge impregnated with a liquid fragrance. The liquid (L) passes through the sponge and may receive a portion of the fragrance impregnated in the sponge.

[0152] In one embodiment, the flavoring module (160) can prevent leakage of the liquid (L). If the liquid (L) is provided directly to the atomizing space (172) without passing through the flavoring module (160), the liquid (L) may leak unnecessarily into the atomizing space (172) or the liquid (L) may be excessively delivered to the atomizing space (172). The flavoring module (160) is provided on the path through which the liquid (L) of the chamber (152) is delivered to the atomizing space (172) so as to reduce or prevent leakage of the liquid (L), or to deliver a uniform liquid (L) to the atomizing space (172) to improve the usability of the aerosol generating device (100).

[0153] In the following, a flavoring module (160) according to various embodiments of the present document is described, and these are merely examples and the structure of the flavoring module (160) is not limited thereto. Additionally, each embodiment is not independent or exclusive, and some components of one embodiment may be omitted, replaced, changed, or added, or at least two embodiments may be combined.

[0154] FIG. 5 is a cross-sectional view of a flavoring module (160a) according to one embodiment.

[0155] Referring to FIG. 5, a steering module (160a) according to one embodiment (e.g., the steering module (160) of FIG. 4b and FIG. 4c) may further include an auxiliary channel (167a).

[0156] In the following description, details that overlap with the above-described content are omitted. It is understood that in the flavoring module (160a), some components and structures may be replaced, added, or omitted to the extent that they are easily understood by those skilled in the art with reference to the drawings and descriptions below. Additionally, at least one component or feature of the previously described embodiments may be combined with the flavoring module (160a) unless it is not technically obvious.

[0157] In one embodiment, the flavoring module (160a) may include a liquid flow path (161a) (e.g., the liquid flow path (161) of FIG. 4b and 4c), a flavoring substance (165a) (e.g., the flavoring substance (165) of FIG. 4b and 4c), an inlet (162a) (e.g., the inlet (162) of FIG. 4b and 4c), and an outlet (163a) (e.g., the outlet (163) of FIG. 4b and 4c).

[0158] In one embodiment, the auxiliary channel (167a) may be partitioned from the liquid channel (161a). The auxiliary channel (167a) may be connected to the liquid hole (153) with the connection between the liquid channel (161a) and the liquid hole (e.g., the liquid hole (153) in FIG. 4b and FIG. 4c) disconnected. The volume of the auxiliary channel (167a) may be relatively small compared to the liquid channel (161a).

[0159] In one embodiment, the auxiliary flow path (167a) may include an auxiliary inlet (168a) and an auxiliary outlet (169a). The auxiliary inlet (168a) may be spaced apart from the inlet (162a). The auxiliary outlet (169a) may be spaced apart from the outlet (163a). The area of ​​the auxiliary outlet (169a) may be relatively smaller compared to the outlet (163a).

[0160] In one embodiment, the auxiliary channel (167a) may not be provided with a flavoring substance (165a). Alternatively, the auxiliary channel (167a) may be provided with a flavoring substance (not shown) different from the flavoring substance (165a) provided in the liquid channel (161a). Hereinafter, one embodiment in which the flavoring substance (165a) is not provided in the auxiliary channel (167a) will be described.

[0161] In one embodiment, the liquid hole (153) may be alternatively connected to either the liquid channel (161a) or the auxiliary channel (167a). For example, the flavoring module (160a) may be assembled to a body (e.g., the body (151) of FIG. 4b and FIG. 4c) such that the liquid hole (153) is alternatively connected to either the liquid channel (161a) or the auxiliary channel (167a).

[0162] For example, the user can separate the flavoring module (160a) from the body (151) and assemble the flavoring module (160a) to the body (151) such that the liquid hole (153) is connected to either the inlet (162a) or the auxiliary inlet (168a).

[0163] For example, if the liquid hole (153) is connected to the liquid path (161a), the liquid may move to the first path (f1). The liquid may pass through the first path (f1) and come into contact with the flavoring substance (165a). The liquid passing through the first path (f1) may be transferred to an atomizing space (e.g., the atomizing space (172) of FIG. 4b and FIG. 4c) with the flavor of the flavoring substance (165a) added.

[0164] For example, if the liquid hole (153) is connected to the auxiliary path (167a), the liquid may move to the second path (f2). The liquid may pass through the second path (f2) without coming into contact with the flavoring substance (165a). The liquid passing through the second path (f2) may be delivered to the atomizing space without adding flavor.

[0165] In one embodiment of the present document, the user may selectively add flavor to the liquid according to preference or usage environment, and the usability of the aerosol generating device (100) may be improved.

[0166] FIG. 6 is a cross-sectional view of a flavoring module (160b) according to one embodiment.

[0168] In the following description, details that overlap with the above-described content are omitted. It is understood that in the flavoring module (160b), some components and structures may be replaced, added, or omitted to the extent that they are easily understood by those skilled in the art with reference to the drawings and descriptions below. Additionally, at least one component or feature of the previously described embodiments may be combined with the flavoring module (160b) unless it is not technically obvious.

[0169] In one embodiment, a plurality of liquid channels (161b) may include a first liquid channel (161b-1) and a second liquid channel (161b-2). The first liquid channel (161b-1) and the second liquid channel (161b-2) may be separated from each other.

[0170] In one embodiment, the first liquid flow path (161b-1) may include a first inlet (162b-1) and a first outlet (163b-1). The second liquid flow path (161b-2) may include a second inlet (162b-2) and a second outlet (163b-2). The first inlet (162b-1) and the second inlet (162b-2) may be spaced apart. The first outlet (163b-1) and the second outlet (163b-2) may be spaced apart.

[0171] In one embodiment, the flavoring module (160b) may include a plurality of flavoring substances (165b) (e.g., flavoring substances (165) of FIG. 4b and FIG. 4c). The plurality of flavoring substances (165b) may include a first flavoring substance (165b-1) provided in a first liquid flow path (161b-1) and a second flavoring substance (165b-2) provided in the second liquid flow path (161b-2).

[0172] In one embodiment, the first flavoring material (165b-1) and the second flavoring material (165b-2) may be different from each other. For example, the flavors of the first flavoring material (165b-1) and the second flavoring material (165b-2) may be different. Alternatively, the concentrations of the flavors of the first flavoring material (165b-1) and the second flavoring material (165b-2) may be different from each other. Alternatively, the composition ratio of the flavors of the first flavoring material (165b-1) and the second flavoring material (165b-2) may be different from each other. Alternatively, the type, physical properties, density, shape, or structure of the porous material of the first flavoring material (165b-1) and the second flavoring material (165b-2) may be different from each other.

[0173] In one embodiment, the first liquid channel (161b-1) may be connected to the liquid hole (153) when the connection between the second liquid channel (161b-2) and the liquid hole (e.g., the liquid hole (153) of FIG. 4b and FIG. 4c) is disconnected. Alternatively, the second liquid channel (161b-2) may be connected to the liquid hole (153) when the connection between the first liquid channel (161b-1) and the liquid hole (153) is disconnected.

[0174] For example, the flavoring module (160b) can be assembled to a body (e.g., body (151) of FIG. 4b and FIG. 4b) such that the liquid hole (153) is optionally connected to either the first liquid channel (161b-1) and the second liquid channel (161b-2).

[0175] For example, the user can separate the flavoring module (160b) from the body (151) and assemble the flavoring module (160b) to the body (151) such that the liquid hole (153) is connected to either the first inlet (162b-1) or the second inlet (162b-2).

[0176] For example, if the liquid hole (153) is connected to the first liquid path (161b-1), the liquid may move to the first path (f1). The liquid may pass through the first path (f1) and come into contact with the first flavoring substance (165b-1). The liquid passing through the first path (f1) may be delivered to an atomizing space (e.g., the atomizing space (172) of FIG. 4b and FIG. 4c) with the flavor of the flavoring substance (165b-1) added.

[0177] For example, if the liquid hole (153) is connected to the second liquid path (161b-2), the liquid may move to the second path (f2). The liquid may pass through the second path (f2) and come into contact with the second flavoring substance (165b-2). The liquid passing through the second path (f2) may be delivered to the atomizing space (172) with the flavor of the flavoring substance (165b-2) added.

[0178] In one embodiment of the present document, the user can select the conditions (e.g., type, concentration, etc.) of the flavor added to the liquid according to preference or usage environment, and the usability of the aerosol generating device (100) can be improved.

[0179] FIG. 7 is a cross-sectional view of a flavoring module (160c) according to one embodiment.

[0180] Referring to FIG. 7, the liquid flow path (161c) (e.g., liquid flow path (161) of FIG. 4b and FIG. 4c) of a flavoring module (160c) according to one embodiment (e.g., flavoring module (160) of FIG. 4b and FIG. 4c) may include a first flow path area (161c-1) and a second flow path area (161c-2).

[0182] In one embodiment, the liquid flow path (161c) may include an inlet (162c) (e.g., the inlet (162) of FIG. 4b and FIG. 4c). The first flow path region (161c-1) and the second flow path region (161c-2) may be mutually partitioned. The first flow path region (161c-1) may branch off from the inlet (162c) and communicate with an atomizing space (e.g., the atomizing space (172) of FIG. 4b and FIG. 4c). The second flow path region (161c-2) may branch off from the inlet (162c) differently from the first flow path region (161c-1) and communicate with the atomizing space (172).

[0183] In one embodiment, the first flow path area (161c-1) may include a first outlet (163c-1). The second flow path area (161c-2) may include a second outlet (163c-2). The first outlet (163c-1) and the second outlet (163c-2) may be spaced apart.

[0185] In one embodiment, the first flavoring material (165c-1) and the second flavoring material (165c-2) may be different from each other. For example, the flavors of the first flavoring material (165c-1) and the second flavoring material (165c-2) may be different. Alternatively, the concentrations of the flavors of the first flavoring material (165c-1) and the second flavoring material (165c-2) may be different from each other. Alternatively, the composition ratio of the flavors of the first flavoring material (165c-1) and the second flavoring material (165c-2) may be different from each other. Alternatively, the type, physical properties, density, shape, or structure of the porous material of the first flavoring material (165c-1) and the second flavoring material (165c-2) may be different from each other.

[0186] In one embodiment, the flavoring module (160c) may further include a switch (168c). The switch (168c) can change the path of the liquid passing through the inlet (162c). For example, the switch (168c) may be movably positioned inside the liquid path (161c).

[0187] In one embodiment, the switch (168c) may be moved automatically by user operation or by the aerosol generating device (100). For example, the switch (168c) may be moved by an operating element provided on the outside of the flavoring module (160c).

[0188] In one embodiment, by moving the switch (168c), the liquid hole (e.g., the liquid hole (153) in FIG. 4b and FIG. 4c) may be alternatively connected to either the first flow path area (161c-1) and the second flow path area (161c-2). The liquid path (f0) through which the liquid (L) is delivered from the liquid hole (153) may be moved to either the first path (f1) or the second path (f2) by the switch (168c).

[0189] For example, if the liquid hole (153) is connected to the first flow path area (161c-1), the liquid may move to the first path (f1). The liquid may pass through the first path (f1) and come into contact with the first flavoring substance (165c-1). The liquid passing through the first path (f1) may be transferred to an atomizing space (e.g., the atomizing space (172) of FIG. 4b and FIG. 4c) with the flavor of the first flavoring substance (165c-1) added.

[0190] For example, if the liquid hole (153) is connected to the second flow path area (161c-2), the liquid can move to the second path (f2). The liquid can pass through the second path (f2) and come into contact with the second flavoring substance (165c-2). The liquid passing through the second path (f2) can be delivered to the atomizing space (172) with the flavor of the second flavoring substance (165c-2) added.

[0191] In one embodiment of the present document, the user can select the conditions of the flavor added to the liquid (e.g., type, concentration, composition ratio of the flavor substance, etc.) according to preference or usage environment, and the usability of the aerosol generating device (100) can be improved.

[0195] In one embodiment, the liquid flow path (161d) may include an inlet (162d) (e.g., the inlet (162) of FIG. 4b and 4c). The main flow path area (161d-1) and the auxiliary flow path area (161d-2) may be mutually partitioned. The main flow path area (161d-1) may branch off from the inlet (162d) and connect to an atomizing space (e.g., the atomizing space (172) of FIG. 4b and 4c). The auxiliary flow path area (161d-2) may branch off from the inlet (162d) differently from the main flow path area (161d-1) and connect to the atomizing space (172).

[0196] In one embodiment, the main flow path area (161d-1) may include a first outlet (163d-1). The auxiliary flow path area (161d-2) may include a second outlet (163d-2). The first outlet (163d-1) and the second outlet (163d-2) may be spaced apart.

[0197] In one embodiment, the flavoring module (160d) may further include a switch (168d). The switch (168d) can change the path of the liquid passing through the inlet (162d). For example, the switch (168d) may be movably positioned inside the liquid path (161d).

[0198] In one embodiment, the switch (168d) may be moved automatically by user operation or by the aerosol generating device (100). For example, the switch (168d) may be moved by an operating element provided on the outside of the flavoring module (160d).

[0199] In one embodiment, by moving the switch (168d), the liquid hole (e.g., the liquid hole (153) in FIG. 4b and FIG. 4c) may be alternatively connected to either the main flow path area (161d-1) and the auxiliary flow path area (161d-2). The liquid path (f0) transmitted from the liquid hole (153) may be moved to either the first path (f1) or the second path (f2) by the switch (168d).

[0200] In one embodiment, the flavoring material (165d) (e.g., the flavoring material (165) of FIG. 4b and FIG. 4c) may be placed only in the main flow area (161d-1) among the main flow area (161d-1) and the auxiliary flow area (161d-2).

[0201] For example, if the liquid hole (153) is connected to the main flow path area (161d-1), the liquid may move to the first path (f1). The liquid may pass through the first path (f1) and come into contact with the flavoring substance (165d). The liquid passing through the first path (f1) may be transferred to an atomizing space (e.g., the atomizing space (172) of FIG. 4b and FIG. 4c) with the flavor of the flavoring substance (165d) added.

[0202] For example, if the liquid hole (153) is connected to the auxiliary flow path area (161d-2), the liquid may move to the second path (f2). The liquid may pass through the second path (f2) without coming into contact with the flavoring substance (165d). The liquid passing through the second path (f2) may be delivered to the atomizing space (172) without adding flavor.

[0203] In one embodiment of the present document, the user may selectively add flavor to the liquid according to preference or usage environment, and the usability of the aerosol generating device (100) may be improved.

[0204] FIG. 9 is a cross-sectional view of a flavoring module (160e) according to one embodiment.

[0205] Referring to FIG. 9, the flavoring material (165e) (e.g., the flavoring material (165) of FIG. 4b and FIG. 4c) of the flavoring module (160e) according to one embodiment (e.g., the flavoring module (160) of FIG. 4b and FIG. 4c) may be composed of a plurality of flavoring elements.

[0206] In the following description, details that overlap with the above-described content are omitted. It is understood that in the flavoring module (160e), some components and structures may be replaced, added, or omitted to the extent that they are easily understood by those skilled in the art with reference to the drawings and descriptions below. Additionally, at least one component or feature of the previously described embodiments may be combined with the flavoring module (160e) unless it is not technically obvious.

[0207] In addition, the following descriptions of the flavoring material (165e) may also be applied to the flavoring materials (165, 165a, 165b, 165c, 165d) of the various embodiments described above.

[0208] In one embodiment, the liquid path (161e) may include an inlet (162e) (e.g., inlet (162) of FIG. 4b and 4c) and an outlet (163e) (e.g., outlet (163) of FIG. 4b and 4c).

[0209] For example, if the liquid hole (153) is connected to the inlet (162e), the liquid can move to the first path (f1). The liquid can come into contact with the flavoring substance (165e) while passing through the first path (f1). The liquid passing through the first path (f1) can be delivered to the atomizing space (e.g., the atomizing space (172) of FIG. 4b and FIG. 4c) with the flavor of the flavoring substance (165e) added.

[0210] In one embodiment, the flavoring material (165e) may consist of a plurality of flavoring elements that can be dissolved by the liquid phase. As the liquid phase passes through the liquid phase channel (161e), the flavoring material (165e) may come into contact with the flavoring material (165e) and the flavoring material (165e) may be dissolved, and the flavor of the flavoring material (165e) may be added to the liquid phase.

[0211] In one embodiment, the flavoring material (165e) may consist of a plurality of flavoring elements that can be melted by the temperature rise of the atomizing space (172). When the aerosol generating device (100) is operated and the temperature of the heater rises, the temperature of the atomizing space (172) may rise. As the temperature of the atomizing space (172) rises, the flavoring material (165e) may melt, and the flavor of the flavoring material (165e) may be added to the liquid.

[0212] In one embodiment, each of the plurality of flavoring elements of the flavoring substance (165e) may be formed in the form of a flavoring capsule. The flavoring capsule may melt due to a liquid or due to a rise in temperature, and the flavor contained inside the flavoring capsule may be mixed with the liquid.

[0213] In one embodiment, the flavoring module (160e) may further include a membrane filter (169e). The membrane filter (169e) may be provided inside the liquid flow path (161e). The membrane filter (169e) can prevent leakage of the liquid.

[0214] In one embodiment, the flavoring substance (165e) may be positioned within the liquid flow path (161e) at a location adjacent to the chamber (152) relative to the atomizing space (172) with respect to the membrane filter (169e). The membrane filter (169e) may allow the passage of the liquid and restrict the passage of the flavoring substance (165e).

[0215] In one embodiment, the membrane filter (169e) can restrict the movement of the liquid. The membrane filter (169e) can prevent the liquid from unnecessarily leaking into the atomizing space (172) or the liquid from being excessively transferred into the atomizing space (172).

[0216] In one embodiment of the present document, the flavoring module (160e) and the membrane filter (169e) can prevent leakage of the liquid and deliver a uniform liquid to the atomizing space (172), thereby improving the usability of the aerosol generating device (100).

[0217] An aerosol generating device according to one embodiment may include a body comprising a chamber for storing a liquid and a liquid hole communicating with the chamber, a flavoring module detachably assembled to the body, and a cap coupled to the flavoring module and having an atomizing space inside. In one embodiment, the flavoring module may include a liquid channel for transferring the liquid from the liquid hole to the atomizing space and a flavoring substance provided inside the liquid channel that contacts the liquid passing through the liquid channel to add flavor.

[0218] In one embodiment, the flavoring module may further include an auxiliary channel partitioned from the liquid channel. In one embodiment, the auxiliary channel is connected to the liquid hole when the connection between the liquid channel and the liquid hole is disconnected, so that the liquid can be transferred from the liquid hole to the atomization space.

[0219] In one embodiment, the flavoring module can be assembled to a body such that a liquid hole is optionally connected to either a liquid channel or an auxiliary channel.

[0220] In one embodiment, the flavoring module may include a plurality of liquid flow paths. In one embodiment, the plurality of liquid flow paths may include a first liquid flow path and a second liquid flow path that are mutually partitioned.

[0221] In one embodiment, the flavoring module may include a plurality of flavoring substances. In one embodiment, the plurality of flavoring substances may include a first flavoring substance provided in a first liquid flow path and a second flavoring substance provided in a second liquid flow path.

[0222] In one embodiment, the flavoring module may be assembled to a body such that a liquid hole is optionally connected to either a first liquid path or a second liquid path.

[0223] In one embodiment, the liquid flow path may include an inlet communicating with a liquid hole, a first flow path region branched from the inlet and communicating with an atomizing space, and a second flow path region branched from the inlet differently from the first flow path region and communicating with an atomizing space.

[0224] In one embodiment, the flavoring module may include a plurality of flavoring materials. In one embodiment, the plurality of flavoring materials may include a first flavoring material disposed in a first flow path region and a second flavoring material disposed in a second flow path region.

[0225] In one embodiment, the flavoring module may further include a switch that changes the movement path of the liquid passing through the inlet.

[0226] In one embodiment, the liquid flow path may include an inlet communicating with a liquid hole, a main flow path area branching from the inlet and communicating with an atomizing space, and an auxiliary flow path area branching from the inlet differently from the main flow path area and communicating with an atomizing space. In one embodiment, the flavoring substance may be placed only in the main flow path area among the main flow path area and the auxiliary flow path area.

[0227] In one embodiment, the flavoring material may consist of a porous material through which a liquid passes and a liquid flavor impregnated in the porous material.

[0228] In one embodiment, the flavoring material may consist of a plurality of flavoring elements that can be dissolved in a liquid phase.

[0229] In one embodiment, the flavoring material may consist of a plurality of flavoring elements that can melt due to the temperature rise of the atomizing space.

[0230] In one embodiment, the flavoring module may further include a membrane filter that is provided inside the liquid path and through which the liquid can pass.

[0231] In one embodiment, the flavoring substance may be placed in a position adjacent to the chamber relative to the atomization space with respect to the membrane filter within the liquid flow path.

[0232] Some or other embodiments of the present disclosure described above are not exclusive or distinct from one another. Some or other embodiments of the present disclosure described above may be used in combination or combined for their respective configurations or functions.

[0233] For example, this means that configuration A described in a specific embodiment and / or drawing and configuration B described in another embodiment and / or drawing can be combined. That is, it means that even if the combination between configurations is not directly described, combination is possible except in cases where it is described that combination is impossible.

[0234] The foregoing detailed description should not be interpreted restrictively in all respects and should be considered exemplary.
