In addition, the attached drawings are only intended to facilitate understanding of the embodiments disclosed in this specification, and the technical concepts disclosed in this specification are not limited by the attached drawings. It should be understood that the attached drawings include all modifications, equivalents, and substitutes included within the spirit and technical scope of the present disclosure.

[0034] Terms that include ordinal numbers, such as first, second, etc., may be used to describe various components. However, these components are not limited by these terms. These terms are used solely to distinguish one component from another.

[0035] When a component is referred to as being "connected" or "connected" to another component, it should be understood that it may be directly connected or connected to that other component, although it should be understood that there may be other components intervening. Conversely, when a component is referred to as being "directly connected" or "connected" to another component, it should be understood that there are no other components intervening.

[0036] Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0037] Throughout this specification, the direction of the aerosol generator and the cartridge may be defined based on an orthogonal coordinate system. In the orthogonal coordinate system, the x-axis direction may be defined as the left-right direction of the aerosol generator and the cartridge. At this time, with respect to the origin, the direction toward +x may mean the right direction, and the direction toward -x may mean the left direction. The y-axis direction may be defined as the front-back direction of the aerosol generator and the cartridge. At this time, with respect to the origin, the direction toward +y may mean the rear direction, and the direction toward -y may mean the front 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.

[0038] Throughout this specification, "upstream" and "downstream" may be determined based on the direction of airflow that causes the generated aerosol to be drawn into the user's mouth or lungs when the user inhales. For example, in FIG. 1, the generated aerosol flows from the heating chamber (44) to the mouthpiece (6), so the heating chamber (44) is located upstream relative to the mouthpiece (6). "Upstream" and "downstream" may be determined relative to components.

[0039]

[0050] Meanwhile, the first heater plate (18A) and the second heater plate (18B) may be arranged along the width direction (x-axis direction) or the depth direction (y-axis direction) of the heating chamber (44). In this case, the first heater plate (18A) and the second heater plate (18B) may be arranged spaced apart from each other in the length direction of the heating chamber (44).

[0051] The heater (18) may include an electrical resistance heater and / or an induction heating heater.

[0052] For example, the first heater plate (18A) and the second heater plate (18B) may be resistive heaters. For example, the first heater plate (18A) and the second heater plate (18B) include electrically conductive tracks, and the first heater plate (18A) and the second heater plate (18B) may be heated as current flows through the electrically conductive tracks. The first heater plate (18A) and the second heater plate (18B) may be electrically connected to a power source (11). The first heater plate (18A) and the second heater plate (18B) may receive power from the power source (11) and directly generate heat.

[0053] For example, the aerosol generator (1) may include an induction coil surrounding at least one of the first heater plate (18A) and the second heater plate (18B). The induction coil may heat the surrounded heater plate. The heater plate surrounded by the induction coil may function as a susceptor and may be heated by a magnetic field generated by an AC current flowing through the induction coil. The magnetic field may penetrate the heater plate and generate an eddy current inside the heater plate. The current may generate heat in the heater plate.

[0054] Meanwhile, a susceptor may be included within a plurality of pouches (21) of the aerosol product (2). The susceptor may be heated by a magnetic field generated by an AC current flowing through an induction coil.

[0055] A cartridge (19) may be coupled to the body (10). The cartridge (19) may contain an aerosol generating material in any one of 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 including a volatile tobacco flavoring component, or may be a liquid containing a non-tobacco material.

[0056] The cartridge (19) can be detachably coupled to, accommodated in, or mounted on the body (10). The cartridge (19) can include a first chamber (C1) and a second chamber (C2). The first chamber (C1) can be positioned above the second chamber (C2). The first chamber (C1) can store an aerosol generating substance therein. The aerosol generating substance can include a flavoring substance. The first chamber (C1) can be formed of a transparent plastic or glass.

[0057] The second chamber (C2) may be positioned below the first chamber (C1). The second chamber (C2) may be in communication with the first chamber (C1). A hole through which fluid may flow may be provided between the first chamber (C1) and the second chamber (C2), so that the first chamber (C1) and the second chamber (C2) may be in communication with each other.

[0058] The second chamber (C2) may be equipped with a wick (25) and a cartridge heater (24). The wick (25) may be connected to the first chamber (C1) and may receive liquid from the first chamber (C1). The wick (25) may be impregnated with liquid. The wick (25) may be fixed within the second chamber (C2). The wick (25) may include a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0059] The cartridge heater (24) can wind the wick (25). The electrically conductive track of the cartridge heater (24) can be formed in a coil-shaped structure that winds the wick (25) or a structure that contacts one side of the wick (25). The cartridge heater (24) can generate heat and heat the wick (25). An end of the cartridge heater (24) can extend to one side of the second chamber (C2) and be electrically connected to an electrode arranged on one side of the cartridge (19).

If necessary, the filter (61) may further include at least one segment for performing another function. The filter (61) may be a cellulose acetate filter.

[0062] When the cartridge heater (24) is heated to heat the wick (25), an aerosol may be formed from the wick (25) within the second chamber (C2). Air passing through the cartridge (19) may be accompanied by the aerosol in the second chamber (C2) and flow into the heating chamber (44) through the first flow path (47A) arranged at the top of the cartridge (19).

[0063] The aerosol generated from the cartridge (19) can be mixed with the aerosol generated by heating the heating target pouch placed in the heating chamber (44) by the heater (18). The mixed aerosol can flow to the mouthpiece (6) through the second flow path (47B) on the upper side of the heating chamber (44). The aerosol passing through the mouthpiece (6) can be inhaled by the user through the user's oral cavity.

[0064] Accordingly, by additionally supplying aerosol from the cartridge (19), a large amount of aerosol can be supplied to the user, thereby increasing user satisfaction.

[0065] In addition, by having a filter (61) inside and a mouthpiece (6) that is separable from the body (10), the mouthpiece (6) can be replaced separately from the aerosol product (2), thereby increasing the replacement cycle of the filter.

[0066] A first door (48) may be provided on one side of the body (10). The first door (48) can open and close the opening of the receiving chamber (43). The first door (48) can be moved in a hinged or sliding manner to open and close the opening of the receiving chamber (43).

The heating target pouch (21A) can be moved so that the aerosol generating material (M) contained therein is positioned between the first heater plate (18A) and the second heater plate (18B).

[0096] The control unit (12) can identify the heating target pouch (21A) (S520). The control unit (12) can identify the heating target pouch (21A) based on a signal received from the pouch detection sensor (138). The control unit (12) can identify at least one of the type of aerosol generating substance (M) contained in the heating target pouch (21A), the capacity of the aerosol generating substance (M), and the order in which the heating target pouch (21A) is arranged on the strip.

[0097] The pouch detection sensor (138) can sense an identification code (22) provided on a pouch (21A) to be heated. The pouch detection sensor (138) can sense the identification code (22) when the pouch (21A) to be heated is accommodated in a connection chamber (45), or can sense the identification code (22) when the pouch (21A) to be heated is moved into a heating chamber (44).

[0098] The control unit (12) can determine a heating profile based on the identification result (S530). The control unit (12) can determine a heating profile for heating the aerosol generating material (M) in the heating target pouch (21A). The heating profile can include at least one of a preheating section and at least one heating section. The preheating section and the at least one heating section can include target heating temperature and heating time information of the section, etc. The control unit (12) can determine target heating temperature and heating time information of each section, etc. based on the type of the identified aerosol generating material (M), the capacity of the aerosol generating material (M), etc.

[0099] Accordingly, by identifying the heating target pouch and setting the heating profile, the heater can be controlled to heat according to the characteristics of the aerosol generating material.

[0100]

[0101] Referring to FIG. 7 together with FIG. 5, the control unit (12) can control the power supplied to the heater (18) based on the determined heating profile (S540). The control unit (12) can control at least one of the first heater plate (18A) and the second heater plate (18B) to move. The control unit (12) can control the heater movement circuit (182) to move at least one of the first heater plate (18A) and the second heater plate (18B).

[0102] With the heating target pouch (21A) placed in the heating chamber (44), at least one of the first heater plate (18A) and the second heater plate (18B) can move in the front-back direction so that the distance between them decreases. By moving at least one of the first heater plate (18A) and the second heater plate (18B), the heating target pouch (21A) can be pressed by the first heater plate (18A) and the second heater plate (18B) in the front-back direction and can come into contact with the first heater plate (18A) and the second heater plate (18B).

[0103] The control unit (12) can control the power supplied from the power source (11) to the heater (18). As the first heater plate (18A) and the second heater plate (18B) generate heat, an aerosol can be generated from an aerosol generating material (M) within the heated pouch (21A).

[0104] Accordingly, by moving the heater to pressurize the pouch to be heated, the contact area between the heater and the aerosol generating substance can be increased, thereby improving the heating efficiency.

[0105]

[0106] Referring to FIGS. 8 and 9 together with FIG. 5, the control unit (12) can control the heating target pouch (21A) to be cut after the heating of the heating target pouch (21A) is terminated (S550). The control unit (12) can control the cutting unit (46) to cut the heating target pouch (21A) by the cutter (46A).

[0107] The cutter drive circuit (46B) can move the cutter (46A) under the control of the control unit (12). The cutter drive circuit (46B) can move the cutter (46A) so that the cutter (46A) crosses the connection chamber (45) in the depth direction of the connection chamber (45). As the cutter (46A) moves, a sharp portion on one side of the cutter (46A) can cut between the heating target pouch (21A) and the pouch (21B) connected to the heating target pouch (21A).

[0108] The control unit (12) can control at least one of the first heater plate (18A) and the second heater plate (18B) to move after the heating of the heating target pouch (21A) is terminated. The control unit (12) can control the heater movement circuit (182) to move at least one of the first heater plate (18A) and the second heater plate (18B).

[0109] At least one of the first heater plate (18A) and the second heater plate (18B) can move in the forward-backward direction so that the distance between them increases. By moving at least one of the first heater plate (18A) and the second heater plate (18B), the pouch (21A) to be heated can be spaced apart from the first heater plate (18A) and the second heater plate (18B) in the forward-backward direction.

[0110] The heated pouch (21A) cut from the strip of the aerosol product (2) can be removed from the body (10). After the heated pouch (21A) is cut, the control unit (12) can control the output unit (14, see FIG. 10) to output information that induces the removal of the pouch. The user can open the second door (492) to remove the cut pouch (21A) from the body (10).

[0111] Accordingly, the used aerosol product can be easily removed by cutting the heated pouch after the heater heating is finished.

[0112] After the heating target pouch (21A) is removed, the control unit (12) can control the movement of the aerosol product (2) accommodated in the receiving chamber (43). The control unit (12) can move the pouch (21B) located at the end of the strip among the plurality of pouches (21) of the aerosol product (2) into the heating chamber (44).

[0113] The control unit (12) can control the operation of the motor (42). The control unit (12) can control the operation of the motor (42) based on the identification information of the pouch (21A) identified in the preceding S520 process. The control unit (12) can control the rotation angle of the motor (42) based on the order information of the pouches (21A) arranged on the strip. The control unit (12) can control the rotation angle of the motor (42) to increase as the order of arrangement on the strip increases.

[0114] In the memory (17, see FIG. 10), information matching the order in which the pouches are arranged on the strip and the rotation angle of the motor can be stored in advance. The control unit (12) can compare the matching information stored in the memory (17) with the order in which the pouches (21A) are arranged on the strip, and control the rotation angle of the motor (42) based on the comparison result.

[0115] In the strip of the aerosol product (2), the further inside the roll the pouch is located, the greater the angle at which the roll must be rotated in order to move the pouch into the heating chamber (44). The control unit (12) can accurately move the pouch into the heating chamber (44) by controlling the rotation angle of the motor (42) based on information about the order in which the pouches (21A) are arranged on the strip.

However, the internal structure of the aerosol generator (1) is not limited to that illustrated in Fig. 10. That is, a person having ordinary skill in the art related to the present embodiment will understand that, depending on the design of the aerosol generator (1), some of the components illustrated in Fig. 10 may be omitted or new components may be added.

[0119] 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 heater (18), restricting smoking, determining whether a stick (S) and / or cartridge (19) is inserted, and displaying a notification are performed.

[0120] The sensor (13) may include at least one of a temperature sensor (131), a puff sensor (132), an insertion detection sensor (133), a reuse detection sensor (134), a cartridge detection sensor (135), an upper case detection sensor (136), a movement detection sensor (137), and a battery detection sensor (138).

[0121] The temperature sensor (131) can detect the temperature at which the cartridge heater (24) and / or the heater (18) is heated. 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 a temperature sensor.

[0122] 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).

[0123] A temperature sensor (131) may be placed around the power supply unit (11) to monitor the temperature of the power supply unit (11). The temperature sensor (131) may be placed adjacent to the power supply unit (11). For example, the temperature sensor (131) may be attached to one side of a battery, which is the power supply unit (11). For example, the temperature sensor (131) may be mounted on one side of a printed circuit board.

[0124] The temperature sensor (131) can be placed inside the body (10) to detect the internal temperature of the body (10). The temperature sensor (131) can be placed outside the body (10) or in a space communicating with the outside of the body (10) to detect the external temperature of the body (10) or the surrounding temperature.

[0125] The puff sensor (132) can detect the user's puff based on various physical changes in the airflow path. The puff sensor (132) can output a signal corresponding to the puff.

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

[0127] An inductive sensor may include at least one coil. The coil of the inductive sensor may be positioned adjacent to an insertion space. For example, when a magnetic field changes around a current-flowing coil, 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.

[0128] An inductive sensor can output a signal corresponding to the characteristics of the current flowing through the coil. For example, an inductive sensor can output a signal corresponding to the inductance value of the coil.

[0129] A capacitance sensor may include a conductor. The conductor of the capacitance sensor may be positioned adjacent to the insertion space. The capacitance sensor may output a signal corresponding to the electromagnetic properties of the surroundings, for example, the electrostatic capacitance around the conductor. For example, when a stick (S) including a wrapper made of a metallic material is inserted into the insertion space, the electromagnetic properties around the conductor may be changed by the wrapper of the stick (S).

[0130] A reuse detection sensor (134) can detect whether the stick (S) has been reused. The reuse detection sensor (134) may be a color sensor. The color sensor can detect the color of the stick (S). The color sensor can detect the color of a portion 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 may be a wavelength of light. The color sensor may be implemented as a single component with the proximity sensor, or may be implemented as a separate component distinct from the proximity sensor.

[0131] At least some of the wrappers constituting the stick (S) may change color due to the aerosol. The reuse detection sensor (134) may be positioned corresponding to a position where at least some of the wrappers whose color changes due to the aerosol are disposed 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 at the second color after changing from the first color to the second color.

[0132] The cartridge detection sensor (135) can detect the mounting and / or removal of the cartridge (19). The cartridge detection sensor (135) can be implemented by an inductance-based sensor, a capacitive sensor, a resistance sensor, a Hall sensor (hall IC) using the Hall effect, etc.

When the upper case (200) is separated from the body (10), the cartridge (19) and a portion of the body (10) covered by the upper case (200) may be exposed to the outside. The upper case detection sensor (136) can be implemented by a contact sensor, a hall sensor (hall IC), an optical sensor, or the like.

[0136] In addition to the sensors (131 to 138) described above, the sensor (13) may further include at least one of a humidity sensor, a position sensor (GPS), a barometric pressure sensor, a magnetic sensor, and a proximity sensor. Since the functions of each sensor can be intuitively inferred by a person skilled in the art from its name, a detailed description thereof may be omitted.

[0137] The output unit (14) can output information on the status of the aerosol generator (1) and provide it to the user. The output unit (14) may include at least one of a display (141), a haptic unit (142), and an audio output unit (143), but is not limited thereto. When the display (141) and the touch pad form a layered structure to form a touch screen, the display unit (141) can be used as an input device in addition to an output device.

[0138] The display (141) can visually provide information about the aerosol generator (1) to the user.

For example, the display (141) may be in the form of an LED light-emitting element. For example, the display (141) may be a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), etc.

[0139] The haptic unit (142) can provide tactile information about the aerosol generator (1) to the user by converting an electrical signal into a mechanical stimulus or an electrical stimulus. For example, the haptic unit (142) can generate a vibration corresponding to the completion of the initial preheating when the initial power is supplied to the cartridge heater (24) and / or heater (18) for a set period of time. The haptic unit (142) can include a vibration motor, a piezoelectric element, or an electrical stimulation device.

[0140] The acoustic output unit (143) can provide information about the aerosol generator (1) to the user audibly. For example, the acoustic output unit (143) can convert an electrical signal into an acoustic signal and output it to the outside.

[0143] The power protection circuit can block the power supply circuit (11) according to certain conditions. For example, the power protection circuit can block the power supply circuit (11) when the voltage level of the power supply circuit (11) is equal to or higher than a first voltage corresponding to overcharge. For example, the power protection circuit can block the power supply circuit (11) when the voltage level of the power supply circuit (11) is lower than a second voltage corresponding to overdischarge.

Although not illustrated in FIG. 10, the device may further include a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, that converts the power of the power supply unit (11) and supplies it to each component. In addition, although not illustrated in FIG. 10, a noise filter may be provided between the power supply unit (11) and the heater (18). The noise filter may be a low pass filter. The low pass filter may include at least one inductor and a capacitor. The cutoff frequency of the low pass filter may correspond to the frequency of the high frequency switching current applied from the power supply unit (11) to the heater (18). The low pass filter can prevent high frequency noise components from being applied to a sensor (13), such as an insertion detection sensor (133).

[0146] In one embodiment, the cartridge heater (24) and / or heater (18) may be formed of any suitable electrically resistive material.

[0156] The control unit (12) can control the overall operation of the aerosol generator (1). In one embodiment, the control unit (12) may include at least one processor. The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, it will be understood by those skilled in the art to which the present embodiment pertains that the processor may be implemented as other types of hardware.

[0157] The control unit (12) can control the temperature of the heater (18) by controlling the supply of power from the power supply unit (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).

[0158] The aerosol generator (1) may include a power supply circuit (not shown) electrically connected to the power supply unit (11) between the power supply unit (11) and the cartridge heater (24) and / or the heater (18). The power supply circuit may be electrically connected to the cartridge heater (24), the heater (18), or the induction coil (181). The power supply circuit may include at least one switching element. The switching element may be implemented by a bipolar junction transistor (BJT), a field effect transistor (FET), or the like. The control unit (12) may control the power supply circuit.

[0159] The control unit (12) can control power supply by controlling the switching of the switching elements of the power supply circuit. The power supply circuit may be an inverter that converts direct current power output from the power supply unit (11) into alternating current power. For example, the inverter may be configured as a full-bridge circuit or a half-bridge circuit including a plurality of switching elements.

[0160] The control unit (12) can turn on the switching element so that power is supplied from the power supply unit (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 supply unit (11) by controlling the frequency and / or duty ratio of the current pulse input to the switching element.

[0161] The control unit (12) can control the voltage output from the power supply unit (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 supply unit (11). For example, the power conversion circuit can include a buck converter that steps down the voltage output from the power supply unit (11). For example, the power conversion circuit can be implemented through a buck-boost converter, a zener diode, etc.

[0162] 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 supply unit (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 supply unit (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.

[0163] The control unit (12) can control power to be supplied to the heater (18) using at least one of the pulse width modulation (PWM) method and the proportional-integral-differential (PID) method.

[0164] 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.

[0165] For example, the control unit (12) can determine a target temperature that is the target of control based on a temperature profile. The control unit (12) can control the power supplied to the heater (18) by using the 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.

[0166] 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 so that the supply of power to the cartridge heater (24) and / or the heater (18) is cut off 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 certain percentage based on the temperature of the cartridge heater (24) and / or the heater (18) exceeding a preset limit temperature.
