[0012] The terminology used in the examples has been selected, as far as possible, to be widely used and general terms, while taking into account the function of the present invention. However, this may vary depending on the intentions of the articulators, precedents, and the emergence of new technologies. In certain cases, the applicant may have arbitrarily selected terms, in which case their meaning will be described in detail in the description of the invention. Therefore, the terms used in the present invention are not merely names of terms, but must be defined based on the meaning of the term and the overall content of the present invention.

[0013] Throughout the specification, when a part states that a certain component "includes" something, unless there is a special statement to the contrary, it does not exclude other components and may further include other components. Also, terms such as "… part" and "… module" described in the specification mean a unit that processes at least one function or operation, and it can be implemented by hardware or software, or also by the combination of hardware and software.

[0014] The term "cigarette" (i.e., when used alone without modifiers such as general, traditional, or combustion type) can refer to an article having a form similar to a traditional combustion cigarette. Such a cigarette may contain an aerosol generating substance that generates an aerosol by the operation (e.g., heating) of an aerosol generating device. Also, optionally, the cigarette may not contain an aerosol generating substance and can transmit an aerosol generated from another article (e.g., a cartridge) provided in the aerosol generating device.

[0015] As used in this specification, when an expression such as "at least any one of" is before an array of components, it modifies the entire components, not each of the arranged components. For example, the expression "at least any one of a, b, and c" should be interpreted to include a, b, c, or a and b, a and c, b and c, or a and b and c. must.

[0016] Hereinafter, based on the accompanying drawings, embodiments of the present invention will be described in detail so that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement them. However, the present invention can be embodied in various different forms and is not limited to the embodiments described here.

[0017] In the embodiments, user authentication means confirming that the user is the owner or owner of the aerosol generator. User authentication also means confirming age or adulthood. Unless otherwise specified in the detailed description or claims, user authentication is defined to include both identity verification and adulthood verification.

[0018] Here, the criteria for adulthood or minority vary from country to country. In South Korea, an adult is defined as someone 19 years of age or older. Furthermore, user authentication also serves as identity verification to confirm the owner of the aerosol generator. Here, the term "user authentication" may include both the age verification process and the identity verification process.

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0020] Figures 1 through 3 show examples of a cigarette being inserted into an aerosol generator.

[0021] Referring to Figure 1, the aerosol generator 1 includes a battery 11, a control unit 12, and a heater 13. Referring to Figures 2 and 3, the aerosol generator 1 further includes a vaporizer 14. A cigarette 2 can also be inserted into the internal space of the aerosol generator 1.

[0022] Figures 1 to 3 illustrate the components of the aerosol generator 1 according to this embodiment. Therefore, a person with ordinary knowledge in the technical field relating to this embodiment will understand that the aerosol generator 1 also includes other general-purpose components in addition to those shown in Figures 1 to 3. Furthermore, although Figures 2 and 3 illustrate that the aerosol generator 1 includes a heater 13, the heater 13 may be omitted if necessary.

[0023] Figure 1 shows the battery 11, control unit 12, and heater 13 arranged in a line. Figure 2 shows the battery 11, control unit 12, vaporizer 14, and heater 13 arranged in a line. Figure 3 shows the vaporizer 14 and heater 13 arranged in parallel. However, the internal structure of the aerosol generator 1 is not limited to what is shown in Figures 1 to 3. That is, the arrangement of the battery 11, control unit 12, heater 13, and vaporizer 14 can be changed depending on the design of the aerosol generator 1.

[0024] When a cigarette 2 is inserted into the aerosol generator 1, the aerosol generator 1 can activate the heater 13 and / or vaporizer 14 to generate an aerosol. The aerosol generated by the heater 13 and / or vaporizer 14 is transmitted to the user through the cigarette 2. If necessary, the aerosol generator 1 can also heat the heater 13 even when the cigarette 2 is not inserted into the aerosol generator 1.

[0025] The battery 11 supplies power used to operate the aerosol generator 1. For example, the battery 11 can supply power to heat the heater 13 or the vaporizer 14, and can also supply power necessary for the operation of the control unit 12. In addition, the battery 11 can supply power necessary for the operation of the display, sensors, motors, etc., provided in the aerosol generator 1.

[0026] The control unit 12 controls the overall operation of the aerosol generator 1. Specifically, the control unit 12 controls the operation of not only the battery 11, heater 13, and vaporizer 14, but also other components included in the aerosol generator 1. The control unit 12 can also check the status of each component of the aerosol generator 1 and determine whether the aerosol generator 1 is in an operational state.

[0027] The control unit 12 includes at least one processor. The processor can also be represented by an array of numerous logic gates, or by a combination of a general-purpose microprocessor and memory in which a program executed by the microprocessor is stored. Furthermore, it can also be represented by other forms of hardware, as will be understood by those with ordinary skill in the art to which this embodiment belongs.

[0028] The heater 13 can be heated by power supplied from the battery 11. For example, if a cigarette is inserted into the aerosol generator 1, the heater 13 can be located outside the cigarette. Therefore, the heated heater 13 can raise the temperature of the aerosol-generating material inside the cigarette.

[0029] The heater 13 is also an electrical resistance heater. For example, the heater 13 includes a conductive track, and the heater 13 can be heated by the flow of current through the conductive track. However, the heater 13 is not limited to the above example, and can be any heater capable of heating to a desired temperature. Here, the desired temperature may already be set in the aerosol generator 1, or it may be set to a desired temperature by the user.

[0030] On the other hand, as another example, heater 13 is also an induction heater. Specifically, heater 13 includes a conductive coil for heating the cigarette by induction heating, and the cigarette may include a susceptor that can be heated by the induction heater. For example, heater 13 includes a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, and the inside or outside of the cigarette 2 can be heated depending on the shape of the heating element.

[0031] Furthermore, the aerosol generator 1 may have multiple heaters 13. In this case, the multiple heaters 13 may be arranged to be inserted inside the cigarette 2, or to be arranged outside the cigarette 2. Also, some of the multiple heaters 13 may be arranged to be inserted inside the cigarette 2, and the rest may be arranged outside the cigarette 2. In addition, the shape of the heater 13 is not limited to the shapes shown in Figures 1 to 3, but can be manufactured in a variety of shapes.

[0032] The vaporizer 14 heats the liquid composition to generate an aerosol, which can then be delivered to the user through the cigarette 2. That is, the aerosol generated by the vaporizer 14 moves along the airflow passage of the aerosol generator 1, and the airflow passage may be configured so that the aerosol generated by the vaporizer 14 is delivered to the user through the cigarette. For example, the vaporizer 14 may include, but is not limited to, a liquid storage unit, a liquid delivery means, and a heating element. For example, the liquid storage unit, the liquid delivery means, and the heating element may be included in the aerosol generator 1 as independent modules.

[0033] The liquid storage section can store liquid compositions. For example, the liquid composition may be a liquid containing tobacco-containing substances, including volatile tobacco flavor components, or a liquid containing non-tobacco substances. The liquid storage section is manufactured to detach from / attach to the vaporizer 14 and may be manufactured integrally with the vaporizer 14. For example, the liquid composition may include water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. The fragrances may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit fragrance components. It is not permitted. Flavoring agents may contain ingredients that can provide users with a variety of flavors or aromas. Vitamin mixtures may also be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Liquid compositions may also contain aerosol-forming agents such as glycerin and propylene glycol.

[0034] The liquid transfer means can transfer the liquid composition of the liquid storage section to the heating element. For example, the liquid transfer means may be, but is not limited to, a wick such as cotton fibers, ceramic fibers, glass fibers, or porous ceramics.

[0035] The heating element is an element for heating the liquid composition transmitted by the liquid transmission means. For example, the heating element may be, but is not limited to, a metal heating wire, a metal heating plate, or a ceramic heater. The heating element may also be composed of a conductive filament, such as a nichrome wire, and may be arranged in a structure wound around the liquid transmission means. The heating element is heated by an electric current supply and can heat the liquid composition by transferring heat to the liquid composition in contact with the heating element. As a result, an aerosol may be generated. For example, the vaporizer 14 may also be called a cartomizer or atomizer, but is not limited to these terms.

[0036] On the other hand, the aerosol generator 1 may further include general-purpose components in addition to the battery 11, control unit 12, heater 13, and vaporizer 14. For example, the aerosol generator 1 may include a display capable of outputting visual information and / or a motor for outputting tactile information. The aerosol generator 1 may also include at least one sensor (such as a puff detection sensor, a temperature detection sensor, or a cigarette insertion detection sensor). Furthermore, the aerosol generator 1 may be constructed in such a way that outside air is allowed to flow in or internal gas is allowed to flow out even when a cigarette 2 is inserted.

[0037] Although not shown in Figures 1 to 3, the aerosol generator 1 may be configured with a separate cradle. For example, the cradle may be used to charge the battery 11 of the aerosol generator 1. Alternatively, the heater 13 may be heated when the cradle and the aerosol generator 1 are coupled together.

[0038] Cigarette 2 is similar to a typical combustible cigarette. For example, Cigarette 2 can be divided into a first part containing an aerosol-generating substance and a second part containing a filter, etc. Alternatively, the second part of Cigarette 2 may also contain an aerosol-generating substance. For example, an aerosol-generating substance made in granular or encapsulated form may be inserted into the second part.

[0039] The entire first part may be inserted into the aerosol generator 1, while the second part may be exposed to the outside. Alternatively, only a portion of the first part may be inserted into the aerosol generator 1, or both the entire first part and a portion of the second part may be inserted. The user can inhale the aerosol with the second part in their mouth. In this case, the aerosol is generated as outside air passes through the first part, and the generated aerosol is transmitted to the user's mouth by passing through the second part.

[0040] As an example, outside air may flow in through at least one air passage formed in the aerosol generator 1. For example, the opening and closing of the air passage formed in the aerosol generator 1 and / or the size of the air passage may be adjusted by the user. This allows the amount of atomization, the smoking sensation, etc., to be adjusted by the user. As another example, outside air may flow into the interior of the cigarette 2 through at least one hole formed on the surface of the cigarette 2.

[0041] The following example of cigarette 2 will be explained with reference to Figures 4 and 5.

[0042] Figures 4 and 5 are diagrams showing examples of cigarettes.

[0043] Referring to Figure 4, the cigarette 2 includes a tobacco rod 21 and a filter rod 22. Referring to Figures 1 to 3, the first part 21 described above includes the tobacco rod 21, and the second part 22 includes the filter rod 22.

[0044] Figure 4 illustrates the filter rod 22 as a single segment, but is not limited to this. That is, the filter rod 22 may also be composed of multiple segments. For example, the filter rod 22 may include a segment for cooling the aerosol and a segment for filtering out predetermined components contained in the aerosol. Furthermore, the filter rod 22 may include at least one additional segment performing other functions as needed.

[0045] A cigarette 2 may be packaged by at least one flap 24. The flap 24 may have at least one hole through which external air enters or internal gases exit. For example, a cigarette 2 may be packaged by one flap 24. As another example, a cigarette 2 may be packaged in layers by two or more flaps 24. For example, the tobacco rod 21 may be packaged by a first flap 241, and the filter rod 22 may be packaged by flap 242, 243, and 244. The entire cigarette 2 may then be repackaged by a single flap 245. If the filter rod 22 consists of multiple segments, each segment may be packaged by flap 242, 243, and 244.

[0046] The tobacco rod 21 contains an aerosol-generating substance. For example, the aerosol-generating substance may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco rod 21 may also contain other additives such as flavoring agents, humectants, and / or organic acids. In addition, a flavoring liquid such as menthol or a humectant can be added to the tobacco rod 21 by spraying it.

[0047] The tobacco rod 21 can be manufactured in various ways. For example, the tobacco rod 21 can be made from a sheet or from a strand. It can also be made from shredded tobacco, which is obtained by finely cutting tobacco sheets. Furthermore, the tobacco rod 21 may be surrounded by a heat-conducting material. For example, the heat-conducting material surrounding the tobacco rod 21 can evenly distribute the heat transferred to the tobacco rod 21, improving the thermal conductivity applied to the tobacco rod and thereby improving the tobacco flavor. Additionally, the heat-conducting material surrounding the tobacco rod 21 can function as a susceptor heated by an induction heater. Although not shown in the diagram, the tobacco rod 21 may also include additional susceptors in addition to the heat-conducting material surrounding its exterior.

[0048] The filter rod 22 is also a cellulose acetate filter. On the other hand, there are no restrictions on the shape of the filter rod 22. For example, the filter rod 22 can be a cylindrical rod, a tubular rod containing a hollow interior, or a recessed rod. If the filter rod 22 is composed of multiple segments, at least one of the segments may be made to have a different shape.

[0049] Furthermore, the filter rod 22 may contain at least one capsule 23. Here, the capsule 23 may perform the function of generating flavor and the function of generating aerosol. For example, the capsule 23 is also a structure that encloses a liquid containing a flavor with a coating. The capsule 23 may be spherical or cylindrical, but is not limited thereto.

[0050] Referring to Figure 5, the cigarette 3 may further include a front plug 33. The front plug 33 can be located on one side of the tobacco rod 31 opposite the filter rod 32. The front plug 33 can prevent the tobacco rod 31 from detaching to the outside and can prevent the liquefied aerosol from flowing from the tobacco rod 31 to the aerosol generator (Figures 1 to 3-1) during smoking.

[0051] The filter rod 32 may include a first segment 321 and a second segment 322. Here, the first segment 321 may correspond to the first segment of the filter rod 22 in Figure 4, and the second segment 322 may correspond to the third segment of the filter rod 22 in Figure 4.

[0052] The diameter and overall length of cigarette 3 may correspond to the diameter and overall length of cigarette 2 in Figure 4. For example, the length of the front plug 33 may be approximately 7 mm, the length of the tobacco rod 31 may be approximately 15 mm, the length of the first segment 321 may be approximately 12 mm, and the length of the second segment 322 may be approximately 14 mm, but are not limited to these dimensions.

[0053] A cigarette 3 may be packaged by at least one flap 35. The flap 35 may have at least one hole through which external air enters or internal gases exit. For example, the front plug 33 may be packaged by a first flap 351, the tobacco rod 31 by a second flap 352, the first segment 321 by a third flap 353, and the second segment 322 by a fourth flap 354. The entire cigarette 3 may then be repackaged by a fifth flap 355.

[0054] Furthermore, at least one perforation 36 may be formed in the fifth trumpet 355. For example, the perforation 36 may be formed in the region surrounding the tobacco rod 31, but is not limited thereto. The perforation 36 can serve to transfer the heat generated by the heater 13 shown in Figures 2 and 3 into the interior of the tobacco rod 31.

[0055] Furthermore, the second segment 322 includes at least one capsule 34. Here, the capsule 34 may perform the function of generating flavor and the function of generating aerosol. For example, the capsule 34 is also a structure that encloses a liquid containing flavor with a coating. The capsule 34 may, but is not limited to, a spherical or cylindrical shape.

[0056] In the embodiments described with reference to Figures 1 to 5, only the insertion of a solid cigarette 3 into the aerosol generator 1 and heating of the cigarette 3 to generate an aerosol were described, but the embodiments are not limited to this. That is, the aerosol generator 1 in the embodiments may also include aerosol generators that generate an aerosol by heating liquid tobacco material, e-vapors, vaporizers, CSV (Close System Vaporizer) electronic cigarettes, liquid-type electronic cigarettes, etc.

[0057] Figure 6 is a block diagram of an aerosol generating apparatus 100 according to one embodiment.

[0058] Referring to Figure 6, the aerosol generator 100 may include an inhalation sensor 410, a communication unit 420, a storage unit 430, an output unit 450, an input unit 460, a battery 470, a heater 480, and a control unit 490. The battery 470 shown in Figure 6 is the same as the battery shown in Figures 1 to 3. In relation to 11, heater 480 can correspond to heater 13 in Figures 1 to 3. Therefore, redundant explanations are omitted.

[0059] The aerosol generator 100 detects the user's inhalation and performs user authentication by comparing the first inhalation data generated by the inhalation with previously stored second inhalation data. Here, user authentication is also age authentication. The aerosol generator 100 activates the device only if it determines, based on a comparison of the inhalation data with age-specific inhalation data, that the user is an adult. Therefore, if it determines that the user is not an adult, i.e., a minor, for example, under 19 years of age, the device can be deactivated and its use prohibited. The aerosol generator 100 also activates the device only if it determines, based on a comparison of the inhalation data with normal inhalation data, that the user is a normal person. Therefore, even if the user is an adult, if it is determined from the inhalation data that their lung capacity is poor or that they have lung health problems, the device can be deactivated and their use prohibited. Further detailed configurations will be described in detail below by referring to each component.

[0060] The inhalation sensor 410 detects the user's inhalation. Here, the inhalation sensor 410 can also be embodied as a pressure sensor, a flow sensor, or a combination thereof. The inhalation sensor 410 may also include a temperature sensor for temperature compensation of the pressure measurement value of the pressure sensor. The inhalation sensor 410 is also a puff sensor.

[0061] The inhalation sensor 410 senses the user's inhalation and provides the sensed data to the control unit 490. For example, as shown in Figure 10, when a user puts the device 100 to their mouth and inhales, the inhalation sensor 410 detects the user's inhalation. Here, inhalation for user authentication is performed in an authentication mode separate from the device's operating mode, and an inhalation guidance message can be displayed or output via the output unit 450 to explain the user authentication process. For example, a message such as "Please inhale strongly for 1 second for user authentication" can be used to improve the accuracy of inhalation data measurement.

[0062] The communication unit 420 communicates with a user terminal (not shown). In this embodiment, the communication unit 420 sends and receives user authentication information with the user terminal. Here, the user terminal may be a mobile terminal or a smartphone, but is not limited to these, and may include a user terminal capable of short-range communication with the aerosol generator 100.

[0063] The communication unit 420 includes, but is not limited to, a short-range communication unit, and may include, for example, a Bluetooth® communication unit, a BLE (Bluetooth® Low Energy, hereinafter referred to as BLE) communication unit, a Near Field Communication Unit (NFC), a WLAN (Wi-Fi) communication unit, a Zigbee® communication unit, an Infrared Data Association (hereinafter referred to as IrDA) communication unit, a WFD (Wi-Fi Direct) communication unit, a UWB (ultra wideband) communication unit, an Ant+ communication unit, etc.

[0064] The storage unit 430 stores information for the operation of the aerosol generator 100. In this embodiment, the storage unit 430 can store information regarding age, lung capacity, and age-specific inhalation data in a database. The storage unit 430 can also store user authentication information.

[0065] Age-specific inhalation data can be calculated using forced vital capacity (FVC), forced vital capacity in one second (FVC1), forced vital capacity in six seconds (FVC6), etc. Forced vital capacity, forced vital capacity in one second, etc. are measured using lung function tests. This is a measurement method used in the examination, which involves measuring the volume and flow rate of air inhaled and exhaled by the subject over time.

[0066] For example, the correlation between forced vital capacity and age can be compiled into a table to construct age-specific inhalation data. Furthermore, if necessary to construct more accurate age-specific inhalation data, the data may be generated while reflecting the effects of body size, such as height and weight.

[0067] The age can be calculated by comparing the inhalation data sensed through the inhalation sensor 410 with age-specific inhalation data using the following formula 1 for forced vital capacity.

[0068] (Equation 1) Forced vital capacity (FVC) = -4.8434 - 0.00008633 * age^2 (years) + 0.05292 * height (cm) + 0.01095 * weight (kg)

[0069] If we exclude the variables related to height and weight, we can further simplify the equation as shown in Equation 2 below.

[0070] (Equation 2) Forced Vital Capacity (FVC)=-4.8434-0.00008633*Age^2 (years)

[0071] In the examples, we explained that age-specific inhalation data was calculated using a forced vital capacity model, but it goes without saying that we are not limited to this, and a variety of age-specific prediction models can be used.

[0072] The output unit 450 may include a display 451, a speaker 452, and a haptic motor 453 for outputting notifications. The output unit 450 can output visual, auditory, and tactile information.

[0073] The display 451 can visually output various alarm messages generated by the aerosol generator 100. For example, the display 451 can output green light when the battery level of the battery 470 is above a pre-set reference level, and orange light when the battery level of the battery 470 is below a pre-set reference level.

[0074] Speaker 452 can audibly output various alarm messages generated by the aerosol generator 100. For example, if the battery level of 470 is above a pre-set reference level, speaker 452 can output a beep sound for a pre-set period of time, and if the battery level of 470 is below a pre-set reference level, speaker 452 can output a beep sound at a pre-set interval.

[0075] The haptic motor 453 can tactilely output various alarm messages generated by the aerosol generator 100. For example, if the remaining charge of the battery 470 is above a pre-set reference charge, the haptic motor 453 can output a first notification by vibrating for a pre-set period of time, and if the remaining charge of the battery 470 is below a pre-set reference charge, it can output a second notification by vibrating at a pre-set frequency.

[0076] The input unit 460 can receive user input. For example, the input unit 460 can receive user input for heating the heater 480. As another example, the input unit 460 can receive user input for varying the display of the output unit 450.

[0077] Battery 470 supplies power to heater 480, and the power supplied to heater 480 is large The size can be adjusted by the control unit 490.

[0078] When an electric current is applied to the heater 480, it generates heat due to its resistivity, and if an aerosol-generating substrate comes into contact with (binds to) the heated heater 480, an aerosol can be generated.

[0079] The control unit 490 can control the power supplied to the heater 480 by transmitting a pulse width modulation (PWM) signal to the heater 480.

[0080] The control unit 490 can heat the heater 480 if the aerosol-generating substrate is inserted into the cavity within a predetermined time. For this purpose, the aerosol generator 100 may further include a substrate sensing sensor (not shown). In some embodiments, the control unit 490 can heat the heater 480 in response to the opening of the cavity 150, or in response to user input received by the input unit 460.

[0081] The control unit 490 compares the first inhalation data obtained from the inhalation sensor 410 with the second inhalation data already stored in the storage unit 430, and performs user authentication based on the comparison result. If the first inhalation data (i.e., the amount of inhalation by the user measured by the inhalation sensor 410) is equal to or greater than the first threshold among the second inhalation data, the control unit 490 performs age authentication and activates the device, determining that age authentication has been successful. Here, the first threshold is also the inhalation data corresponding to a 19-year-old, for example, 4.86 FVC (liters), based on the age-specific inhalation data stored in the storage unit 430. Therefore, adult authentication is determined to be complete only when the amount of inhalation sensed through the inhalation sensor 410 is 4.86 or greater.

[0082] Furthermore, the control unit 490 may perform normal person authentication and activate the device if the first inhalation data is equal to or greater than the second threshold among the second inhalation data. Here, the second threshold is also the inhalation value that serves as the standard for the lung capacity of a normal person. Therefore, even if adult authentication is performed, the device can be made unusable if the lung function is poor. For example, even if an adult has lung capacity at the level of an infant or the elderly, the use of the device may be prohibited.

[0083] Here, it was explained that the control unit 490 makes a decision based on or by loading previously stored inhalation data in the storage unit 430. However, the control unit 490 itself can have a reference value for adult inhalation data pre-set, and can directly determine whether the inhalation data obtained from the inhalation sensor 410 is above or below the reference value, thereby activating or deactivating the device.

[0084] Furthermore, the control unit 490 can analyze the first inhalation data acquired by the inhalation sensor 410 and generate inhalation pattern data including the inhalation cycle and inhalation intensity. The control unit 490 may perform user authentication by comparing the user inhalation pattern data corresponding to the generated inhalation pattern data with the inhalation pattern data already stored in the storage unit 430. Here, user authentication includes identity verification. The control unit 490 may additionally or selectively perform age authentication using age-specific inhalation data and identity verification using inhalation pattern data. Therefore, even if adult authentication is completed, the device can be activated only after identity verification of the device is completed, thereby preventing unauthorized use by minors or users who are not the intended user.

[0085] Figure 7 is a block diagram of an aerosol generating apparatus 100 according to another embodiment.

[0086] Referring to Figure 7, the aerosol generator 100 shown in Figure 6 further includes a motion sensor 440. Here, we will mainly describe a user authentication configuration using the motion sensor 440.

[0087] The motion sensor 440 can detect the movement of the aerosol generating device 100. Examples of motion sensors 440 include, but are not limited to, acceleration sensors, gyroscopes, and angular velocity sensors. Here, the movement of the device follows a predetermined pattern; for example, if the user holds the device 100 in their hand and draws a Z-shape, as shown in Figure 11, the motion sensor 440 can recognize the movement pattern.

[0088] The control unit 490 compares motion data acquired from the motion sensor 440 with user authentication motion data stored in the storage unit 430, and activates the device only if they match. Here, user authentication using the motion sensor 440 can be used in addition to or selectively to the user authentication using the aforementioned inhalation data and user authentication using the inhalation pattern data.

[0089] Figures 8 and 9 are diagrams illustrating user authentication between the aerosol generator 100 and the user terminal 300 according to yet another embodiment.

[0090] Referring to both Figures 6 and 8, the aerosol generator 100 and the user terminal 300 can perform short-range communication and user authentication using the user terminal 300 according to the embodiment.

[0091] As explained with reference to Figure 6, the aerosol generator 100 can perform short-range communication with the user terminal 300 via the communication unit 430.

[0092] If user authentication fails, that is, if user authentication using inhalation data obtained through the inhalation sensor 410 fails, the control unit 490 transmits an authentication control command to the user terminal 300 connected to a predetermined network via the communication unit 430.

[0093] Furthermore, if user authentication via the aerosol generator 100 fails, the user may optionally execute the user authentication application on the user terminal 300, and if the aerosol generator 100 is within a predetermined distance from the user terminal 300, user authentication may be performed through an authentication method on the user terminal 300, such as fingerprint recognition or security key input.

[0094] As shown in Figure 9, a user authentication application is executed in the user terminal 300 in response to an authentication control command transmitted from the aerosol generator 100, and user authentication is performed. User authentication performed in the user terminal 300 may be, but is not limited to, various known user authentication methods such as iPIN authentication, official certificates, mobile phone number authentication, and biometric information authentication.

[0095] In the embodiment, user authentication is difficult using only the inhalation data acquired through the inhalation sensor 410 of the aerosol generator 100. For example, if accurate user authentication fails using only forced vital capacity measurement, the aerosol generator 100 transmits the inhalation data to the user terminal 300. The user terminal 300 may perform user authentication by combining the transmitted inhalation data with previously stored user information, such as user age information and physical information. In that case, the user terminal 300 may also be configured to run a user authentication application and perform a simplified pulmonary function test based on the transmitted inhalation data.

[0096] If authentication is successful at the user terminal 300, the control unit 490 performs user authentication using the authentication information transmitted from the user terminal 300 and activates the device. Here, the authentication information includes identity verification and age verification, and each piece of authentication information may be received encrypted.

[0097] In the example, the aerosol generator 100 measures using the inhalation sensor of the device itself. Even if user authentication using the inhalation data fails, the inconvenience to the user due to the device's authentication failure can be resolved by proceeding with user authentication in conjunction with the user terminal 300 as an additional authentication method.

[0098] Furthermore, in this embodiment, the device may only be activated after the user completes additional authentication using a user terminal to enhance authentication, even after successful authentication using inhalation data. Therefore, user authentication protection is strengthened, and the risk of authentication errors can be reduced.

[0099] Figures 12 to 15 are flowcharts illustrating the control method of an aerosol generating apparatus according to further embodiments.

[0100] Referring to Figure 12, in step 1200, first inhalation data is obtained from an inhalation sensor that detects the user's inhalation. In step 1202, the obtained first inhalation data is compared with the previously stored second inhalation data. In step 1204, user authentication is performed based on the comparison result. Although not shown, if user authentication is successful, the device may be activated.

[0101] Referring to Figure 13, in step 1300, the first inhalation data is obtained from the inhalation sensor that detects the user's inhalation. In step 1302, the first inhalation data is compared with age-specific inhalation data. In step 1304, it is determined whether the first inhalation data is above or below the first threshold. Here, the first threshold is also the reference value for inhalation data corresponding to a specific age, based on age-specific inhalation data. For example, it is the average inhalation data corresponding to a 19-year-old. In steps 1306 and 1308, if age authentication is completed, the device is activated.

[0102] In step 1310, if age verification fails, the device is deactivated.

[0103] Referring to Figure 14, in step 1400, first inhalation data is obtained from the inhalation sensor that detects the user's inhalation. In step 1402, the first inhalation data is compared with normal inhalation data. In step 1404, it is determined whether the first inhalation data is above the second threshold. Here, the second threshold is also the reference value for inhalation data of a normal or healthy person. In steps 1406 and 1408, if normal person authentication is completed, the device is activated.

[0104] In step 1410, if normal person authentication fails, the device is deactivated.

[0105] Referring to Figure 15, in steps 1500 and 1502, if authentication based on inhalation data fails, the network connection to the user terminal is checked. For example, if user authentication fails on the device, the presence or absence of a user terminal is checked within a predetermined distance, for example, within a distance where short-range communication is possible. In step 1504, an authentication control command is transmitted to the user terminal. In step 1506, the user authentication application is executed on the user terminal. In step 1508, if user authentication is successful on the user terminal, in step 1510, the aerosol generator receives authentication information from the user terminal, and in step 1512, performs user authentication based on the received authentication information. For example, if the authentication information indicates that user authentication was successful on the user terminal, the aerosol generator 100 can perform step 1514. In step 1514, if user authentication is successful, the device is activated.

[0106] In stage 1516, if user authentication fails on the user terminal, the authentication application may terminate, or authentication failure information may be transmitted to the aerosol generator.

[0107] In the embodiment, activating the aerosol generator 100 after successful user authentication may include opening and closing the cavity into which the aerosol generating substrate is inserted, preheating the heater, or setting the device to an operating mode.

[0108] In this embodiment, multiple user authentication methods, including identity verification or age verification, can be performed. These include age verification, which compares inhalation data sensed from user inhalation with age-specific inhalation data; identity verification, which compares inhalation pattern data generated based on inhalation data sensed from user inhalation with previously stored inhalation pattern data; identity verification, which compares the device's movement pattern with previously stored movement patterns; and user verification, which sends and receives authentication information with a user terminal connected to the network.

[0109] In the embodiments, one or more of the above-described authentication methods may be performed. Furthermore, for enhanced security, multiple authentication procedures may be performed sequentially, and the aerosol generator cannot be activated until the user has passed all authentication procedures. In this case, if pre-authentication is successful for each authentication method, further authentication can be performed for enhanced security. Selectively, in other embodiments, if one authentication process fails, the user may attempt other authentication processes to activate the aerosol generator. In this case, the aerosol generator will be activated once the user has passed one of the many authentication procedures. Those with ordinary skill in the art relating to these embodiments will understand that they may be embodied in modified forms that do not deviate from the essential characteristics described above. Therefore, the disclosed methods should be considered in an explanatory rather than restrictive view. The scope of the present invention is disclosed in the claims, not in the foregoing description, and all differences within an equivalent scope should be interpreted as being included in the present invention.
