Description

Aerosol generator

The present disclosure relates to an aerosol generating device.

An aerosol generating device is intended to extract a certain component from a medium or substance through an aerosol. The medium may contain substances of various components. The substances contained in the medium may be flavoring substances of various components. For example, the substances contained in the medium may contain nicotine components, herbal components, and/or coffee components. Recently, much research has been conducted on such aerosol generating devices.

The aerosol generated from the aerosol generator is a high-temperature gas, and can be cooled while flowing inside the device before being inhaled by the user. However, depending on the usage environment of the aerosol generator, the aerosol may contain heated moisture, and the moisture may be inhaled by the user without being sufficiently cooled. In this case, the user may feel a foreign sensation. In addition, the possibility of the user being burned by the heated moisture cannot be ruled out.

However, conventional aerosol generating devices have a problem in that they do not have a means to prevent leakage of liquid inside the aerosol.

The present disclosure aims to solve the above-mentioned and other problems.

Another object may be to provide an aerosol generating device having a membrane having selective permeability disposed on the euro of the cartridge.

Another object may be to provide an aerosol generating device having a membrane having selective permeability disposed on a body of the device.

Another object may be to provide an aerosol generating device having an additional path for compensating for variations in suction resistance.

According to one aspect of the present disclosure for achieving the above-described object, there is provided an aerosol generating device comprising: a body providing an insertion space with one side opened; a cartridge coupled with the body, the cartridge including a first container storing liquid therein; and a second container disposed adjacent to the first container and having a wick supplied with liquid from the first container and a heater heated by the wick therein; a first channel communicating between the insertion space and the interior of the second container; and a second channel through which outside air is introduced and communicates with the first channel at one side of the first channel, wherein a first membrane having selective permeability is disposed in the first channel.

According to at least one embodiment of the present disclosure, a membrane having selective permeability is disposed on the flow path of the cartridge, thereby preventing leakage of high-temperature liquid outside the cartridge, thereby reducing a feeling of heat felt by a user.

According to at least one embodiment of the present disclosure, a membrane having selective permeability is disposed on the flow path of the cartridge, thereby reducing the problem of liquid leakage outside the cartridge.

According to at least one embodiment of the present disclosure, by arranging a membrane on the flow path of the body, the problem of aerosol flowing inside the body being cooled and resulting droplets being inhaled by the user can be reduced.

According to at least one embodiment of the present disclosure, the cartridge is provided with an additional flow structure to compensate for the increased suction resistance caused by the membrane.

Further scope of the applicability of the present disclosure will become apparent from the detailed description below.

At this time, with respect to the origin, the direction toward +y may mean the rearward direction, and the direction toward -y may mean the forward direction. The z-axis direction may be defined as the up-down direction of the aerosol generator and the cartridge. With respect to the origin, the direction toward +z may mean the upward direction, and the direction toward -z may mean the downward direction.

Throughout this specification, "upstream" and "downstream" may be determined based on the direction of airflow in which the generated aerosol flows so that it is inhaled into the user's mouth or lungs when the user inhales. For example, in FIGS. 1 and 2, since the generated aerosol flows from the inserted portion of the aerosol generating device in the stick (S) to the non-inserted portion, the inserted portion of the stick (S) is located upstream of the non-inserted portion. "Upstream" and "downstream" may be determined relatively between components.

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

Referring to FIGS. 1 and 2, the aerosol generating device (1) may include at least one of a power source (11), a control unit (12), a sensor (13), a heater (18), and a cartridge (19). At least one of the power source (11), the control unit (12), the sensor (13), and the heater (18) may be disposed inside a body (10) of the aerosol generating device. The body (10) may provide a space opened upwardly so that a stick (S), which is an aerosol generating article, may be inserted. The space opened upwardly may be referred to as an insertion space. The insertion space may be formed by being sunken toward the inside of the body (10) to a predetermined depth so that at least a portion of the stick (S) may be inserted. The depth of the insertion space may correspond to the length of a region in the stick (S) containing an aerosol generating material and/or a medium. The lower end of the stick (S) is inserted into the inside of the body (10), and the upper end of the stick (S) can protrude outside of the body (10). The user can put the upper end of the stick (S) exposed to the outside in his mouth and inhale air.

The heater (18) can heat the stick (S). The heater (18) can be extended upwardly around the space where the stick (S) is inserted. For example, the heater (18) can be in the form of a tube having a hollow portion therein. The heater (18) can be arranged around the periphery of the insertion space. The heater (18) can be arranged to surround at least a portion of the insertion space. The heater (18) can heat the insertion space or the stick (S) inserted into the insertion space. The heater (18) can include an electrical resistance heater and/or an induction heating heater.

For example, the heater (18) may be a resistive heater. For example, the heater (18) may include an electrically conductive track, and the heater (18) may be heated as current flows through the electrically conductive track. The heater (18) may be electrically connected to a power source (11). The heater (18) may be directly heated by receiving current from the power source (11).

For example, the aerosol generator (1) may include an induction coil surrounding a heater (18). The induction coil may heat the heater (18). The heater (18) may be a susceptor, and the heater (18) may be heated by a magnetic field generated by an AC current flowing through the induction coil. The magnetic field may pass through the heater (18) and generate an eddy current within the heater (18). The current may generate heat in the heater (18).

Meanwhile, a susceptor may be included inside the stick (S), and the susceptor inside the stick (S) may be heated by a magnetic field generated by an AC current flowing through the induction coil.

The cartridge (19) may contain an aerosol generating material having any one of a liquid state, a solid state, a gaseous state, or a gel state therein. The aerosol generating material may include a liquid composition. For example, the liquid composition may be a liquid including a tobacco-containing material including a volatile tobacco flavoring component, or may be a liquid including a non-tobacco material.

The cartridge (19) may be formed integrally with the body (10) or may be detachably coupled to the body (10).

For example, referring to FIG. 1, the cartridge (19) is formed integrally with the body (10) and can be communicated with the insertion space through an airflow channel (CN).

For example, referring to FIG. 2, a space is formed on one side of the body (10), and at least a portion of the cartridge (19) is inserted into the space formed on one side of the body (10) so that the cartridge (19) can be mounted on the body (10). The airflow channel (CN) can be defined by a portion of the cartridge (19) and/or a portion of the body (10), and the cartridge (19) can be communicated with the insertion space through the airflow channel (CN).

The body (10) can be formed in a structure in which outside air can flow into the interior of the body (10) while the cartridge (19) is inserted. At this time, the outside air that flows into the body (10) can pass through the cartridge (19) and flow into the user's oral cavity.

The cartridge (19) may include a storage portion (C1) containing an aerosol generating material and/or a heater (24) for heating the aerosol generating material in the storage portion (C1). The storage portion (C1) may be referred to as a container. At least a portion of a liquid delivery means (25, see FIG. 6) impregnated with (containing) the aerosol generating material may be disposed inside the storage portion (C1). Here, the liquid delivery means (25) may include a wick such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, etc. The electrically conductive track of the heater (24) may be formed as a coil-shaped structure that winds the liquid delivery means (25) or a structure that contacts one side of the liquid delivery means (25). The heater (24) may be referred to as a cartridge heater (24).

The cartridge (19) can generate an aerosol. As the liquid delivery means (25) is heated by the cartridge heater (24), the aerosol can be generated. The aerosol can be generated by heating the stick (S) by the heater (18). While the aerosol generated by the cartridge heater (24) and the heater (18) passes through the stick (S), tobacco material can be added to the aerosol, and the aerosol added with the tobacco material can be inhaled into the user's mouth through one end of the stick (S).

The aerosol generator (1) may be equipped with only a cartridge heater (24) and the body (10) may not be equipped with a heater (18). At this time, the aerosol generated by the cartridge heater (24) may pass through the stick (S) and be inhaled into the user's mouth with tobacco material added thereto.

The aerosol generator (1) may include an upper case (not shown). The upper case may be detachably coupled to the body (10) so as to cover at least a portion of a cartridge (19) coupled to the body (10). A stick (S) may be inserted into the body (10) by penetrating the upper case.

The power source (11) can supply power to operate components of the aerosol generator. The power source (11) can be referred to as a battery. The power source (11) can supply power to at least one of the control unit (12), the sensor (13), the cartridge heater (24), and the heater (18).

The control unit (12) can check the status of each component of the aerosol generator to determine whether the aerosol generator is in an operable state.

The control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the cartridge heater (24) and/or the heater (18) so that the operation of the cartridge heater (24) and/or the heater (18) is started or ended based on the results detected by the sensor (13). For example, the control unit (12) can control the amount of power supplied to the cartridge heater (24) and/or the heater (18) and the time for which the power is supplied so that the cartridge heater (24) and/or the heater (18) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor (13).

The sensor (13) may include at least one of a temperature sensor, a puff sensor, an insertion detection sensor, a color sensor, a cartridge detection sensor, and an upper case detection sensor. For example, the sensor (13) may sense at least one of a temperature of a heater (18), a temperature of a power source (11), and a temperature inside and outside the body (10). For example, the sensor (13) may sense a puff of a user. For example, the sensor (13) may sense whether a stick (S) is inserted into an insertion space. For example, the sensor (13) may sense whether a cartridge is mounted. For example, the sensor (13) may sense whether an upper case is mounted.

Air introduced through the second cartridge inlet (306) can flow inside the second flow path (52) and flow into the first flow path (51) through the junction (53). The air inside the first flow path (51) can be mixed with the aerosol in the first flow path (51) and flow into the body (10) through the first flow path (51).

The first flow path (51) may be provided with a first membrane (54). The first membrane (54) may be arranged in a direction intersecting the longitudinal direction of the first flow path (51), so as to cross the first flow path (51) and block one end of the first flow path (51). The first membrane (54) may be arranged in a direction intersecting the longitudinal direction of a discharge flow path (305) forming a part of the first flow path (51), so as to cross the discharge flow path (305) and block one end of the discharge flow path (305).

The first membrane (54) may be a membrane having selective permeability. The first membrane (54) may be a film. The first membrane (54) may selectively allow a fluid to pass through it.

The first membrane (54) may block the liquid inside the second chamber (C2) from flowing out of the cartridge (19) through the second flow path (52) and the second inlet port (306). The first membrane (54) is The liquid inside the second chamber (C2) can be blocked from being inhaled by the user through the cartridge (19) and body (10).

Accordingly, the problem of liquid leaking outside the cartridge can be reduced, and the heat sensation felt by the user when inhaling high-temperature liquid can be lowered.

Accordingly, by providing an additional second flow path in the cartridge, the increased suction resistance caused by the membrane can be compensated.

The width of the second flow path (52) may be smaller than the width of the first flow path (51). For example, the maximum width of the second flow path (52) may be smaller than the width of the discharge flow path (305) defining a portion of the first flow path (51). For example, the maximum width of the second flow path (52) may be smaller than the width of the connecting flow path (433) defining a portion of the first flow path (51).

By arranging the first membrane (54) on the first flow path (51) through which the aerosol generated in the second chamber (C2) flows, the suction resistance for the fluid flow through the first flow path (51) may increase. If the suction resistance of the first flow path (51) increases, the amount of aerosol and/or air that the user can inhale may decrease even if the user inhales with the same force.

A cartridge (19) according to one embodiment can compensate for a decrease in the amount of aerosol and/or air that a user can inhale by additionally providing a second passage (52). However, if the flow of fluid through the second passage (52) is greater than the flow of fluid through the first passage (51), the user may feel a foreign sensation when inhaling.

By forming the width of the second flow path (52) narrower than that of the first flow path (51), the foreign feeling that the user may feel when inhaling can be reduced. In other words, the ratio of the suction resistance of the second flow path (52) to that of the first flow path (51) can be appropriately adjusted through the ratio of the width of the second flow path (52) to that of the first flow path (51).

The second flow path (52) may be provided with a second membrane (55). The second membrane (55) may be arranged between one end and the other end of the second flow path (52).

The second membrane (55) may be arranged upstream of the junction (53) on the second flow path (52). The second membrane (55) may be arranged adjacent to one end of the second flow path (52) that communicates with the exterior of the cartridge (19) on the second flow path (52). The second membrane (55) may be arranged adjacent to the second cartridge inlet (306) on the second flow path (52).

The second membrane (55) can block liquid outside the cartridge (19) from flowing into the cartridge (19). The second membrane (55) can block liquid or droplets generated within the first flow path (51) and/or the second flow path (52) from flowing out of the cartridge (19) through the second inlet (306).

Accordingly, the problem of liquid leaking outside the cartridge can be reduced.

The second membrane (55) can act as a flow resistance component for external air flowing into the second passage (52) by the user's inhalation. That is, the second membrane (55) can increase the suction resistance for the fluid flow through the second passage (52).

Since the second membrane (55) is placed on the second path (52) that is connected to the first path (51), the foreign sensation that the user may feel when inhaling can be reduced. That is, the ratio of the suction resistance of the second path (52) and the suction resistance of the first path (51) can be appropriately adjusted by the second membrane (55).

However, the internal structure of the aerosol generator (1) is not limited to that illustrated in Fig. 13. That is, a person having ordinary skill in the art related to the present embodiment will understand that some of the components illustrated in Fig. 13 may be omitted or new components may be added depending on the design of the aerosol generator (1).

The sensor (13) can detect the status of the aerosol generator (1) or the status around the aerosol generator (1) and transmit the detected information to the control unit (12). Based on the detected information, the control unit (12) can control the aerosol generator (1) so that various functions such as controlling the operation of the cartridge heater (24) and/or the heater (18), restricting smoking, determining whether a stick (S) and/or cartridge (19) is inserted, and displaying a notification are performed.

The aerosol generator (1) may include a separate temperature sensor that detects the temperature of the cartridge heater (24) and/or the heater (18), or the cartridge heater (24) and/or the heater (18) itself may serve as the temperature sensor.

The temperature sensor (131) can output a signal corresponding to the temperature of the cartridge heater (24) and/or the heater (18). For example, the temperature sensor (131) can include a resistance element whose resistance value changes in response to a change in the temperature of the cartridge heater (24) and/or the heater (18). It can be implemented by a thermistor, which is an element that utilizes the property of changing resistance depending on temperature. At this time, the temperature sensor (131) can output a signal corresponding to the resistance value of the resistance element as a signal corresponding to the temperature of the cartridge heater (24) and/or the heater (18). For example, the temperature sensor (131) can be configured as a sensor that detects the resistance value of the cartridge heater (24) and/or the heater (18). At this time, the temperature sensor (131) can output a signal corresponding to the resistance value of the cartridge heater (24) and/or the heater (18) as a signal corresponding to the temperature of the cartridge heater (24) and/or the heater (18).

The temperature sensor (131) may be placed around the power source (11) to monitor the temperature of the power source (11).

For example, the insertion detection sensor (133) may be an inductive sensor and/or a capacitance sensor.

The inductive sensor may include at least one coil. The coil of the inductive sensor may be arranged adjacent to the insertion space. For example, when a magnetic field changes around a coil through which current flows, the characteristics of the current flowing in the coil may change according to Faraday's law of electromagnetic induction. Here, the characteristics of the current flowing in the coil may include the frequency of the alternating current, the current value, the voltage value, the inductance value, the impedance value, etc.

The capacitance sensor may include a conductor. The conductor of the capacitance sensor may be arranged adjacent to the insertion space. The capacitance sensor may output a signal corresponding to an electromagnetic characteristic of the surroundings, for example, an electrostatic capacitance of the surroundings of the conductor. For example, when a stick (S) including a wrapper made of a metal material is inserted into the insertion space, the electromagnetic characteristic of the surroundings of the conductor may be changed by the wrapper of the stick (S).

The reuse detection sensor (134) can detect whether the stick (S) is reused. The reuse detection sensor (134) can be a color sensor. The color sensor can detect the color of the stick (S). The color sensor can detect the color of a part of a wrapper that wraps the outside of the stick (S). The color sensor can detect a value for an optical characteristic corresponding to the color of an object based on light reflected from the object. For example, the optical characteristic can be a wavelength of light. The color sensor can be implemented as a single configuration with the proximity sensor, or can be implemented as a separate configuration distinct from the proximity sensor.

At least some of the wrappers constituting the stick (S) may change color due to the aerosol. The reuse detection sensor (134) may be arranged in response to a position where at least some of the wrappers whose color changes due to the aerosol are arranged when the stick (S) is inserted into the insertion space. For example, before the stick (S) is used by a user, the color of at least some of the wrappers may be a first color. At this time, as at least some of the wrappers are wetted by the aerosol generated by the aerosol generating device (1) while passing through the stick (S), the color of at least some of the wrappers may change to a second color. Meanwhile, the color of at least some of the wrappers may be maintained as the second color after changing from the first color to the second color.

The humidity sensor (138) can be implemented by a capacitive sensor, etc. The humidity sensor (138) can be positioned on the outside of the body (10) or located on a path through which outside air is introduced, and can measure the humidity around the aerosol generator (1). The humidity sensor (138) can be positioned in the storage portion (C1) of the cartridge (19) and can measure the humidity inside the cartridge (19).

In addition to the sensors (131 to 138) described above, the sensor (13) may further include at least one of a pressure sensor, a magnetic sensor, a position sensor (GPS), and a proximity sensor.

The control unit (12) can control the overall operation of the aerosol generating device (1). In one embodiment, the control unit (12) can include at least one processor. The processor can be implemented as an array of a plurality of logic gates, or can be implemented as a combination of a general-purpose microprocessor and a memory storing a program that can be executed in the microprocessor. In addition, it will be understood by those skilled in the art to which the present embodiment belongs that the processor can be implemented as other types of hardware.

The control unit (12) can control the temperature of the heater (18) by controlling the supply of power from the power source (11) to the heater (18). The control unit (12) can control the temperature of the cartridge heater (24) and/or the heater (18) based on the temperature of the cartridge heater (24) and/or the heater (18) sensed by the temperature sensor (131). The control unit (12) can adjust the power supplied to the cartridge heater (24) and/or the heater (18) based on the temperature of the cartridge heater (24) and/or the heater (18). For example, the control unit (12) can determine a target temperature for the cartridge heater (24) and/or the heater (18) based on a temperature profile stored in the memory (17).

The aerosol generator (1) may include a power supply circuit (not shown) electrically connected to the power supply (11) between the power supply (11) and the cartridge heater (24) and/or the heater (18).

The control unit (12) can turn on the switching element so that power is supplied from the power source (11) to the cartridge heater (24) and/or the heater (18). The control unit (12) can turn off the switching element so that power is cut off to the cartridge heater (24) and/or the heater (18). The control unit (12) can control the current supplied from the power source (11) by controlling the frequency and/or duty ratio of the current pulse input to the switching element.

The control unit (12) can control the voltage output from the power source (11) by controlling the switching of the switching element of the power supply circuit. The power conversion circuit can convert the voltage output from the power source (11). For example, the power conversion circuit can include a buck converter that steps down the voltage output from the power source (11). For example, the power conversion circuit can be implemented through a buck-boost converter, a zener diode, etc.

The control unit (12) can control the on/off operation of the switching element included in the power conversion circuit to adjust the level of the voltage output from the power conversion circuit. When the on state of the switching element continues, the level of the voltage output from the power conversion circuit may correspond to the level of the voltage output from the power source (11). The duty ratio for the on/off operation of the switching element may correspond to the ratio of the voltage output from the power conversion circuit to the voltage output from the power source (11). As the duty ratio for the on/off operation of the switching element decreases, the level of the voltage output from the power conversion circuit may decrease. The heater (18) can be heated based on the voltage output from the power conversion circuit.

The control unit (12) can control power to be supplied to the heater (18) by using at least one of the pulse width modulation (PWM) method and the proportional-integral-differential (PID) method.

For example, the control unit (12) can control a current pulse having a predetermined frequency and duty ratio to be supplied to the heater (18) using the PWM method. The control unit (12) can control the power supplied to the heater (18) by adjusting the frequency and duty ratio of the current pulse.

For example, the control unit (12) can determine a target temperature that is a target of control based on a temperature profile. The control unit (12) can control the power supplied to the heater (18) by using a PID method, which is a feedback control method using a difference value between the temperature of the heater (18) and the target temperature, a value obtained by integrating the difference value over time, and a value obtained by differentiating the difference value over time.

The control unit (12) can prevent the cartridge heater (24) and/or the heater (18) from overheating. For example, the control unit (12) can control the operation of the power conversion circuit to cut off the supply of power to the cartridge heater (24) and/or the heater (18) based on the temperature of the cartridge heater (24) and/or the heater (18) exceeding a preset limit temperature. For example, the control unit (12) can reduce the amount of power supplied to the cartridge heater (24) and/or the heater (18) by a predetermined ratio based on the temperature of the cartridge heater (24) and/or the heater (18) exceeding a preset limit temperature. For example, the control unit (12) can determine that the aerosol generating material contained in the cartridge (19) is exhausted based on the temperature of the cartridge heater (24) exceeding a preset limit temperature, and can cut off the supply of power to the cartridge heater (24).

The control unit (12) can control the charging and discharging of the power supply (11). The control unit (12) can check the temperature of the power supply (11) based on the output signal of the temperature sensor (131).

When a power line is connected to the battery terminal of the aerosol generator (1), the control unit (12) can check whether the temperature of the power source (11) is equal to or higher than the first limit temperature, which is a criterion for blocking charging of the power source (11). When the temperature of the power source (11) is lower than the first limit temperature, the control unit (12) can control the power source (11) to be charged based on a preset charging current. When the temperature of the power source (11) is equal to or higher than the first limit temperature, the control unit (12) can block charging of the power source (11).

When the power of the aerosol generator (1) is turned on, the control unit (12) can check whether the temperature of the power source (11) is equal to or higher than the second limit temperature, which is a criterion for blocking discharge of the power source (11). If the temperature of the power source (11) is lower than the second limit temperature, the control unit (12) can control to use the power stored in the power source (11). If the temperature of the power source (11) is equal to or higher than the second limit temperature, the control unit (12) can stop using the power stored in the power source (11).

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).

The control unit (12) can determine whether a stick (S) is inserted into the insertion space through the insertion detection sensor (133). The control unit (12) can determine that the stick (S) is inserted based on the output signal of the insertion detection sensor (133). If it is determined that the stick (S) is inserted into the insertion space, the control unit (12) can control to supply power to the cartridge heater (24) and/or the heater (18). For example, the control unit (12) can supply power to the cartridge heater (24) and/or the heater (18) based on the temperature profile stored in the memory (17).

The control unit (12) can determine whether the stick (S) is removed from the insertion space. For example, the control unit (12) can determine whether the stick (S) is removed from the insertion space through the insertion detection sensor (133). For example, the control unit (12) can determine that the stick (S) is removed from the insertion space when the temperature of the heater (18) is higher than a limited temperature or when the temperature change slope of the heater (18) is higher than a set slope. When it is determined that the stick (S) is removed from the insertion space, the control unit (12) can cut off the power supply to the cartridge heater (24) and/or the heater (18).

The control unit (12) can control the power supply time and/or power supply amount to the heater (18) according to the state of the stick (S) detected by the sensor (13). The control unit (12) can check the level range that includes the level of the signal of the capacitance sensor based on a lookup table. The control unit (12) can determine the moisture content of the stick (S) according to the checked level range.

When the stick (S) is in an over-humidified state, the control unit (12) can control the power supply time to the heater (18) to increase the preheating time of the stick (S) compared to the normal state.

The control unit (12) can determine whether the stick (S) inserted into the insertion space is reused through the reuse detection sensor (134). For example, the control unit (12) can compare the sensing value of the signal of the reuse detection sensor with a first reference range that includes a first color, and if the sensing value is included in the first reference range, it can determine that the stick (S) has not been used. For example, the control unit (12) can compare the sensing value of the signal of the reuse detection sensor with a second reference range that includes a second color, and if the sensing value is included in the second reference range, it can determine that the stick (S) has been used. If it is determined that the stick (S) has been used, the control unit (12) can cut off the supply of power to the cartridge heater (24) and/or the heater (18).

The control unit (12) can determine whether the cartridge (19) is coupled and/or removed through the cartridge detection sensor (135). For example, the control unit (12) can determine whether the cartridge (19) is coupled and/or removed based on the sensing value of the signal of the cartridge detection sensor.

The control unit (12) can determine whether the aerosol generating material of the cartridge (19) is exhausted. For example, the control unit (12) can preheat the cartridge heater (24) and/or the heater (18) by applying power, and determine whether the temperature of the cartridge heater (24) exceeds a limit temperature during the preheating section. If the temperature of the cartridge heater (24) exceeds the limit temperature, the control unit (12) can determine that the aerosol generating material of the cartridge (19) is exhausted. If the control unit (12) determines that the aerosol generating material of the cartridge (19) is exhausted, the control unit (12) can cut off the supply of power to the cartridge heater (24) and/or the heater (18).

The control unit (12) can determine whether the cartridge (19) is usable. For example, the control unit (12) can determine that the cartridge (19) cannot be used if the current number of puffs is greater than or equal to the maximum number of puffs set for the cartridge (19) based on data stored in the memory (17). For example, the control unit (12) can determine that the cartridge (19) cannot be used if the total time that the heater (24) has been heated is greater than or equal to the preset maximum time or the total amount of power supplied to the heater (24) is greater than or equal to the preset maximum amount of power.

The control unit (12) can perform a judgment regarding the user's inhalation through the puff sensor (132). For example, the control unit (12) can determine whether a puff has occurred based on the sensing value of the signal of the puff sensor.
