By adjusting the current flowing through the conductive coil, the induction heater can generate an alternating magnetic field whose direction is periodically changed. At this time, when an alternating magnetic field is applied to the magnet, energy loss may occur in the magnet due to eddy current loss and hysteresis loss. In addition, the lost energy may be released as thermal energy. Thus, the aerosol-generating substance located in the vicinity of the magnet may be heated. Here, the object generating heat due to the magnetic field may be referred to as a susceptor.
Meanwhile, the aerosol-generating module 13 may generate ultrasonic vibrations to generate an aerosol from the aerosol-generating substance.
The aerosol generating device 10 may be referred to as a cartomizer (cartomizer), a nebulizer (atomizer), or a vaporizer (vaporizer).
The memory 14 may store a program for processing and controlling each signal in the controller 17. The memory 14 may store processed data and data to be processed.
For example, the memory 14 may store applications designed to perform various tasks that may be handled by the controller 17. The memory 14 may selectively provide some of the stored applications in response to a request from the controller 17.
For example, the memory 14 may store data regarding an operation time of the aerosol-generating device 10, a maximum number of puffs, a current number of puffs, a number of uses of the battery 16, at least one temperature profile, a user's inhalation pattern, and data regarding charge/discharge. Here, "suction" refers to inhalation by the user. "inhalation" refers to the act of drawing air or other substances into the user's mouth, nasal cavity, or lungs through the user's mouth or nose.
The memory 14 may include at least one of volatile memory (e.g., dynamic Random Access Memory (DRAM), static Random Access Memory (SRAM), or Synchronous Dynamic Random Access Memory (SDRAM)), non-volatile memory (e.g., flash memory), a Hard Disk Drive (HDD), or a Solid State Drive (SSD).
The sensor module 15 may include at least one sensor.
For example, the sensor module 15 may include a sensor for sensing suction (hereinafter referred to as a "suction sensor"). In this case, the suction sensor may be implemented as a proximity sensor, such as an IR sensor, a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.
For example, the sensor module 15 may include a sensor for sensing suction (hereinafter referred to as a "suction sensor"). In this case, the suction sensor may be implemented by a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.
For example, the sensor module 15 may include a sensor (hereinafter referred to as "temperature sensor") for sensing the temperature of the heater included in the aerosol-generating module 13 and the temperature of the aerosol-generating substance. In this case, the heater included in the aerosol-generating module 13 may also be used as a temperature sensor. For example, the resistive material of the heater may be a material having a predetermined temperature coefficient of resistance. The sensor module 15 may measure the resistance of the heater according to the temperature change, thereby sensing the temperature of the heater.
For example, in the case where the body of the aerosol-generating device 10 is formed to allow insertion of a rod therein, the sensor module 15 may include a sensor for sensing insertion of the rod (hereinafter referred to as a "rod detection sensor").
For example, in the case where the aerosol-generating device 10 includes a cartridge, the sensor module 15 may include a sensor for sensing the attachment/detachment of the cartridge and the position of the cartridge (hereinafter referred to as "cartridge detection sensor").
In this case, the rod detection sensor and/or the cartridge detection sensor may be implemented as an inductance-based sensor, a capacitance sensor, a resistance sensor, or a hall sensor (or hall IC) using the hall effect.
For example, the sensor module 15 may include a voltage sensor for sensing a voltage applied to a component (e.g., the battery 16) provided in the aerosol-generating device 10 and/or a current sensor for sensing a current.
The battery 16 may supply power for operating the aerosol-generating device 10 under the control of the controller 17. The battery 16 may supply power to other components disposed in the aerosol-generating device 10. For example, the battery 16 may supply power to a communication module included in the communication interface 11, an output device included in the input/output interface 12, and a heater included in the aerosol generating module 13.
The battery 16 may be a rechargeable battery or a disposable battery. For example, the battery 16 may be a lithium-ion (Li-ion) battery or a lithium polymer (Li-polymer) battery. However, the present disclosure is not limited thereto. For example, when the battery 16 is rechargeable, the charge rate (C-rate) of the battery 16 may be 10C, and the discharge rate (C-rate) thereof may be 10C to 20C. However, the present disclosure is not limited thereto. Further, for stable use, the battery 16 may be manufactured such that 80% or more of the total capacity can be ensured even when 2000 charge/discharge is performed.
The aerosol generating device 10 may also include a battery Protection Circuit Module (PCM) (not shown), which is a circuit for protecting the battery 16. A battery Protection Circuit Module (PCM) may be disposed adjacent to an upper surface of the battery cell 16. For example, in order to prevent overcharge and overdischarge of the battery 16, when an overvoltage is applied to the battery 16 when a short circuit occurs in a circuit connected to the battery 16, or when an overcurrent flows through the battery 16, a battery Protection Circuit Module (PCM) may cut off an electrical path to the battery 16.
The aerosol generating device 10 may further comprise a charging terminal to which electric power supplied from the outside is input. For example, the charging terminal may be formed at one side of the main body of the aerosol-generating device 10. The aerosol generating device 10 may charge the battery 16 using the electric power supplied through the charging terminal. In this case, the charging terminal may be configured as a wired terminal for USB communication, pogo pin, or the like.
The aerosol-generating device 10 may further comprise a power terminal (not shown) to which power supplied from the outside is input. For example, the power line may be connected to a power terminal provided at one side of the main body of the aerosol-generating device 10. The aerosol-generating device 10 may charge the battery 16 using electric power supplied through a power line connected to the power terminal. In this case, the power terminal may be a wired terminal for USB communication.
The aerosol-generating device 10 may wirelessly receive power supplied from the outside through the communication interface 11. For example, the aerosol-generating device 10 may wirelessly receive power using an antenna included in a communication module for wireless communication. The aerosol generating device 10 may charge the battery 16 using wirelessly supplied power.
The controller 17 may control the overall operation of the aerosol-generating device 10. The controller 17 may be connected to each component provided in the aerosol-generating device 10. The controller 17 may send and/or receive signals to and/or from each component to control the overall operation of each component.
The controller 17 may include at least one processor. The controller 17 may use a processor included therein to control the overall operation of the aerosol-generating device 10. Here, the processor may be a general-purpose processor such as a Central Processing Unit (CPU). Of course, the processor may be a special purpose device, such as an Application Specific Integrated Circuit (ASIC), or may be any other hardware-based processor.
The controller 17 may perform any of a variety of functions of the aerosol-generating device 10. For example, the controller 17 may perform any one of various functions (e.g., a warm-up function, a heating function, a charging function, and a cleaning function) of the aerosol-generating device 10 according to the state of each component provided in the aerosol-generating device 10 and a user command received through the input/output interface 12.
The controller 17 may control the operation of each component provided in the aerosol-generating device 10 based on data stored in the memory 14. For example, the controller 17 may control the supply of a predetermined amount of electric power from the battery 16 to the aerosol-generating module 13 for a predetermined time based on data about the temperature distribution, the inhalation pattern of the user, stored in the memory 14.
The controller 17 may use a suction sensor included in the sensor module 15 to determine whether suction is occurring or not. For example, the controller 17 may check the temperature change, the flow rate change, the pressure change, and the voltage change of the aerosol-generating device 10 based on the values sensed by the suction sensor. The controller 17 may determine the occurrence or non-occurrence of aspiration based on the value sensed by the aspiration sensor.
The controller 17 may control the operation of each component provided in the aerosol-generating device 10 according to the number of times that suction is or is not occurring and/or is being sucked. For example, the controller 17 may perform control such that the temperature of the heater is changed or maintained based on the temperature distribution stored in the memory 14.
The controller 17 may perform control such that the power supply to the heater is interrupted according to a predetermined condition. For example, the controller 17 may perform control such that when the stick is removed, when the cartridge is detached, when the number of times of suction reaches a predetermined maximum number of times of suction, when suction is not sensed for a predetermined period of time or more, or when the remaining capacity of the battery 16 is less than a predetermined value, power supply to the heater is interrupted.
The controller 17 may calculate the remaining capacity with respect to the full charge capacity of the battery 16. For example, the controller 17 may calculate the remaining capacity of the battery 16 based on values sensed by a voltage sensor and/or a current sensor included in the sensor module 15.
The controller 17 may perform control such that the heater is supplied with power using at least one of a Pulse Width Modulation (PWM) method or a proportional-integral-derivative (PID) method.
For example, the controller 17 may perform control such that a current pulse having a predetermined frequency and a predetermined duty ratio is supplied to the heater using a PWM method. In this case, the controller 17 can control the amount of electric power supplied to the heater by adjusting the frequency and the duty ratio of the current pulses.
For example, the controller 17 may determine the target temperature to be controlled based on the temperature distribution. In this case, the controller 17 may control the amount of electric power supplied to the heater using a PID method that is a feedback control method using a difference between the temperature of the heater and the target temperature, a value obtained by integrating the difference with respect to time, and a value obtained by differentiating the difference with respect to time.
Although the PWM method and the PID method are described as examples of a method of controlling power supply to the heater, the present disclosure is not limited thereto, and any one of various control methods, such as a proportional-integral (PI) method or a proportional-derivative (PD) method, may be employed.
Meanwhile, the controller 17 may perform control such that power is supplied to the heater according to a predetermined condition. For example, when a cleaning function for cleaning a space of an insertion rod is selected in response to a command input by a user through the input/output interface 12, the controller 17 may perform control such that a predetermined amount of power is supplied to the heater.
Fig. 2 to 4 are views for explaining an aerosol-generating device according to an embodiment of the present disclosure.
According to various embodiments of the present disclosure, the aerosol-generating device 10 may include a body 100 and/or a cartridge 200.
Referring to fig. 2, the aerosol-generating device 10 according to an embodiment may include a body 100 and a cartridge 200. The body 100 may support the cartridge 200, and the cartridge 200 may contain an aerosol-generating substance.
According to one embodiment, the cartridge 200 may be configured to be removably mounted to the body 100. According to another embodiment, the cartridge 200 may be integrally configured with the body 100. For example, the cartridge 200 may be mounted to the body 100 in such a manner that at least a portion of the cartridge 200 is inserted into an insertion space formed by the housing 101 of the body 100.
The main body 100 may be formed to have a structure in which external air may be introduced into the main body 100 in a state in which the cartridge 200 is inserted. Here, the external air introduced into the main body 100 may flow into the mouth of the user via the cartridge 200.
The controller 17 may use a cartridge detection sensor included in the sensor module 15 to determine whether the cartridge 200 is in the installed state or in the disassembled state. For example, the cartridge detection sensor may transmit pulsed current through a first terminal connected to the cartridge 200. In this case, the controller 17 may determine whether the cartridge 200 is in the connected state based on whether the pulse current is received through the second terminal.
The cartridge 200 may include a heater 210 configured to heat the aerosol-generating substance and/or a reservoir 220 configured to contain the aerosol-generating substance. For example, a liquid delivery element impregnated with (containing) an aerosol-generating substance may be disposed within the reservoir 220. The conductive traces of the heater 210 may be formed in a structure that wraps around the liquid transport element. In this case, when the liquid delivery element is heated by the heater 210, an aerosol may be generated. Here, the liquid transport element may comprise a core made of, for example, cotton fibers, ceramic fibers, glass fibers or porous ceramics.
The cartridge 200 may include a suction nozzle 225. Here, the mouthpiece 225 may be a portion inserted into the mouth of the user. The mouthpiece 325 may have a discharge hole through which the aerosol is discharged to the outside during suction.
Referring to fig. 3, the cartridge 200 may include an insertion space 230 configured to allow insertion of the rod 20. For example, the cartridge 200 may include an insertion space formed by an inner wall extending in a circumferential direction along the direction of the insertion rod 20. In this case, the insertion space may be formed by opening the inner side of the inner wall up and down. The rod 20 may be inserted into an insertion space formed by the inner wall.
The insertion space into which the rod 20 is inserted may be formed in a shape corresponding to a shape of a portion of the rod 20 inserted into the insertion space. For example, when the rod 20 is formed in a cylindrical shape, the insertion space may be formed in a cylindrical shape.
When the rod 20 is inserted into the insertion space, the outer surface of the rod 20 may be surrounded by and contact with the inner wall.
A portion of the rod 20 may be inserted into the insertion space, and the remaining portion of the rod 20 may be exposed to the outside.
A user may inhale the aerosol while biting one end of the rod 20 with the mouthpiece. The aerosol generated by the heater 210 may pass through the rod 20 and be delivered to the user's mouth. At this time, as the aerosol passes through the rod 20, the material contained in the rod 20 may be added to the aerosol. An aerosol of infusion material may be inhaled into the user's mouth through one end of the rod 20.
The controller 17 may monitor the number of puffs based on a value sensed by a puff sensor from a point in time when the wand 20 is inserted into the main body.
When the wand 20 is removed from the main body, the controller 17 may initialize the current number of puffs stored in the memory 14.
Referring to fig. 4, the aerosol-generating device 10 according to the embodiment may include a main body 100 supporting a cartridge 200 and a cartridge 200 containing an aerosol-generating substance. The body 100 may be formed to allow the rod 20 to be inserted into the insertion space 130 therein.
The aerosol-generating device 10 may comprise a first heater for heating the aerosol-generating substance stored in the cartridge 200. For example, when a user holds one end of the rod 20 in the mouth to inhale the aerosol, the aerosol generated by the first heater may pass through the rod 20. At this time, a fragrance may be added to the aerosol as it passes through the rod 20. The aerosol containing the fragrance may be inhaled into the user's mouth through one end of the wand 20.
Alternatively, according to another embodiment, the aerosol-generating device 10 may comprise a first heater for heating the aerosol-generating substance stored in the cartridge 200 and a second heater for heating the rod 20 inserted into the body 100. For example, the aerosol-generating device 10 may generate an aerosol by heating the aerosol-generating substance stored in the cartridge 200 and the rod 20 using the first heater and the second heater, respectively.
Rod 20 may resemble a conventional combustion cigarette. For example, the rod 20 may be divided into a first portion comprising aerosol generating material and a second portion comprising a filter or the like. Alternatively, the aerosol generating material may be included in the second portion of the rod 20. For example, a flavouring substance in the form of granules or capsules may be inserted into the second portion.
Fig. 5 to 7 are views for explaining a stick according to an embodiment of the present disclosure.
Referring to fig. 5, the rod 20 may include a tobacco rod 21 and a filter rod 22. The first portion described above with reference to fig. 2 may comprise a tobacco rod. The second portion described above with reference to fig. 2 may include filter rods 22.
Fig. 5 shows that the filter rod 22 comprises a single segment. However, the filter rod 22 is not limited thereto. In other words, the filter rod 22 may comprise a plurality of segments. For example, the filter rod 22 may include a first segment configured to cool the aerosol and a second segment configured to filter specific components contained in the aerosol. Moreover, the filter rod 22 may also include at least one segment configured to perform other functions, as desired.
The diameter of the rod 20 may be in the range of 5mm to 9mm, and the length of the rod 20 may be about 48mm, but the embodiment is not limited thereto. For example, the length of the tobacco rod 21 may be about 12mm, the length of the first segment of the filter rod 22 may be about 10mm, the length of the second segment of the filter rod 22 may be about 14mm, and the length of the third segment of the filter rod 22 may be about 12mm, although the embodiments are not limited in this respect.
The rod 20 may be wrapped with at least one wrapper 24. The wrapper 24 may have at least one hole through which external air may be introduced or through which internal air may be exhausted. For example, a wrapper 24 may be used to wrap the rod 20. As another example, the rod 20 may be double wrapped with at least two wraps 24. For example, the tobacco rod 21 may be wrapped with a first wrapper 241. For example, the filter rod 22 may be wrapped with wrappers 242, 243, 244. The tobacco rod 21 and filter rod 22 wrapped by the wrapper may be combined. Rod 20 may be repacked by a single wrapper 245. When each of the tobacco rod 21 and filter rod 22 includes multiple segments, each segment may be wrapped with a wrap 242, 243, 244. The entire rod 20, consisting of multiple segments wrapped by a wrapper, may be repacked by another wrapper.
The first wrapper 241 and the second wrapper 242 may be formed of a common filter wrapper. For example, the first wrapper 241 and the second wrapper 242 may be porous wrapper paper or non-porous wrapper paper. Further, the first wrapper 241 and the second wrapper 242 may be made of an oil resistant paper sheet and an aluminum laminate packaging material.
The third wrapper 243 may be made of hard wrap paper. For example, the basis weight of the third wrap 243 may be in the range of 88g/m2 to 96g/m 2. For example, the basis weight of the third wrap 243 may be in the range of 90g/m2 to 94g/m 2. Further, the total thickness of the third wrapper 243 may be in the range of 1200 μm to 1300 μm. For example, the total thickness of the third wrapper 243 may be 125 μm.
The fourth wrapper 244 may be made of oil resistant hard wrapping paper. For example, the basis weight of the fourth wrapper 244 may be in the range of about 88g/m2 to about 96g/m 2. For example, the basis weight of the fourth wrapper 244 may be in the range of 90g/m2 to 94g/m 2. Further, the total thickness of the fourth wrap 244 may be in the range of 1200 μm to 1300 μm. For example, the total thickness of the fourth wrap 244 may be 125 μm.
The fifth wrapper 245 may be made of sterile paper (MFW). Here, MFW refers to specially manufactured paper having enhanced tensile strength, water resistance, smoothness, and the like as compared to plain paper. For example, the basis weight of the fifth wrapper 245 may be in the range of 57g/m2 to 63g/m 2. For example, the basis weight of the fifth wrapper 245 may be about 60g/m2. Further, the total thickness of the fifth wrapper 245 may be in the range of 64 μm to 70 μm. For example, the total thickness of the fifth wrapper 245 may be 67 μm.
The predetermined material may be included in the fifth wrapper 245. Here, an example of the predetermined material may be, but is not limited to, silicon. For example, silicon exhibits characteristics such as heat resistance that hardly change due to temperature, oxidation resistance, resistance to various chemicals, water resistance, electrical insulation, and the like. However, any material other than silicon may be applied to (or coated on) the fifth wrapper 245 without limitation, so long as the material has the above-described characteristics.
The fifth wrapper 245 may prevent the burning of the rod 20. For example, when the tobacco rod 21 is heated by the heater 110, there is a possibility that the rod 20 burns. In detail, the rod 20 may burn when the temperature increases to a temperature above the ignition point of any of the materials contained in the tobacco rod 21. Even in this case, since the fifth wrapper 245 includes a non-combustible material, the burning of the rod 20 can be prevented.
In addition, the fifth wrapper 245 may prevent the aerosol-generating device 10 from being contaminated by the substance formed by the rod 20. By suction from the user, a liquid substance may be formed in the wand 20. For example, when the aerosol formed by the rod 20 is cooled by outside air, a liquid material (e.g., moisture, etc.) may be formed. When the fifth wrapper 245 wraps the rod 20, the liquid material formed in the rod 20 may be prevented from leaking out of the rod 20.
The tobacco rod 21 may include an aerosol generating material. For example, the aerosol-generating material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. In addition, the tobacco rod 21 may include other additives such as flavorants, humectants, and/or organic acids. In addition, the tobacco rod 21 may include a flavored liquid, such as menthol or a humectant, that is impregnated into the tobacco rod 21.
The tobacco rod 21 may be made in various forms. For example, the tobacco rod 21 may be formed as a sheet or wire. Further, the tobacco rod 21 may be formed as cut filler, which is formed from small pieces cut from a sheet of tobacco. Moreover, the tobacco rod 21 may be surrounded by a thermally conductive material. For example, the thermally conductive material may be, but is not limited to, a metal foil such as aluminum foil. For example, the thermally conductive material surrounding the tobacco rod 21 may evenly distribute the heat transferred to the tobacco rod 21, and thus, the thermal conductivity applied to the tobacco rod may be increased, and the taste of the tobacco may be improved. Moreover, the thermally conductive material surrounding the tobacco rod 21 may act as a susceptor that is heated by an induction heater. Here, although not shown in the figures, the tobacco rod 21 may include an additional susceptor in addition to the thermally conductive material surrounding the tobacco rod 21.
The filter rod 22 may comprise a cellulose acetate filter. The shape of the filter rod 22 is not limited. For example, the filter rod 22 may comprise a cylindrical rod or tubular rod having a hollow interior. Also, the filter rod 22 may comprise a fluted rod. When the filter rod 22 includes a plurality of segments, at least one of the plurality of segments may have a different shape.
The first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first section may be a tubular structure having a hollow interior. The first segment may prevent the interior material of the tobacco rod 21 from being pushed back when the heater 110 is inserted into the tobacco rod 21 and may also provide a cooling effect for the aerosol. The diameter of the hollow included in the first section may be a suitable diameter in the range of 2mm to 4.5mm, but is not limited thereto.
The length of the first segment may be a suitable length in the range of 4mm to 30mm, but is not limited thereto. For example, the length of the first section may be 10mm, but is not limited thereto.
The second section of the filter rod 22 cools the aerosol generated when the heater 110 heats the tobacco rod 21. Thus, the user can suck the aerosol cooled at an appropriate temperature.
The length or diameter of the second segment may be determined differently depending on the shape of the rod 20. For example, the length of the second section may be a suitable length in the range of 7mm to 20 mm. Preferably, the length of the second section may be about 14mm, but is not limited thereto.
The second segment may be made by braiding polymer fibers. In this case, the flavouring liquid may also be applied to the fibres formed from the polymer. Alternatively, the second segment may be manufactured by braiding together additional fibers coated with a flavored liquid and fibers formed from a polymer. Alternatively, the second section may be formed from a curled polymeric sheet.
For example, the polymer may be formed of a material selected from the group consisting of Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose Acetate (CA), and aluminum coil.
When the second segment is formed from woven polymer fibers or crimped polymer sheets, the second segment may include a single channel or multiple channels extending in the longitudinal direction. Here, a channel refers to a channel through which a gas (e.g., air or aerosol) passes.
For example, the second segment formed from the crimped polymer sheet may be formed from a material having a thickness of between about 5 μm and about 300 μm, such as between about 10 μm and about 250 μm. Likewise, the total surface area of the second section may be between about 300mm2/mm and about 1000mm 2/mm. Furthermore, the aerosol-cooling element may be formed from a material having a specific surface area of between about 10mm2/mg and about 100mm 2/mg.
The second section may comprise a thread containing volatile flavour ingredient. Here, the volatile fragrance ingredient may be menthol, but is not limited thereto. For example, the strands may be filled with a sufficient amount of menthol to provide a second segment having 1.5mg or more menthol.
The third segment of the filter rod 22 may be a cellulose acetate filter. The length of the third section may be a suitable length in the range of 4mm to 20 mm. For example, the length of the third section may be about 12mm, but is not limited thereto.
The filter rod 22 may be manufactured to produce a flavor. For example, a flavored liquid can be injected onto the filter rod 22. For example, additional fibers coated with a flavored liquid may be inserted into the filter rod 22.
Furthermore, the filter rod 22 may comprise at least one capsule 23. Here, the capsules 23 may generate fragrance. The capsule 23 may generate an aerosol. For example, the pouch 23 may have a configuration in which a liquid including a flavoring material is wrapped by a film. The bladder 23 may have a spherical or cylindrical shape, but is not limited thereto.
Referring to fig. 6, rod 30 may also include a front end plug 33. The front end plug 33 may be located on a side of the tobacco rod 31 that does not face the filter rod 32. The front end plug 33 prevents separation of the tobacco rod 31 and prevents liquefied aerosol from flowing from the tobacco rod 31 into the aerosol-generating device 10 during smoking.
The filter rod 32 may include a first segment 321 and a second segment 322. The first segment 321 may correspond to the first segment of the filter rod 22 of fig. 4. The second segment 322 may correspond to the third segment of the filter rod 22 of fig. 4.
The diameter and overall length of rod 30 may correspond to the diameter and overall length of rod 20 of fig. 4. For example, the length of the front end plug 33 may be about 7mm, the length of the tobacco rod 31 may be about 15mm, the length of the first section 321 may be about 12mm, and the length of the second section 322 may be about 14mm, but the embodiment is not limited thereto.
The rod 30 may be wrapped with at least one wrapper 35. The wrapper 35 may have at least one hole through which external air may be introduced or through which internal air may be discharged. For example, front end plug 33 may be wrapped with a first wrapper 351, tobacco rod 31 may be wrapped with a second wrapper 352, first section 321 may be wrapped with a third wrapper 353, and second section 322 may be wrapped with a fourth wrapper 354. Moreover, the entire rod 30 may be repacked using a fifth wrapper 355.
In addition, at least one perforation 36 may be formed in the fifth wrapper 355. For example, perforations 36 may be formed in the area of fifth wrapper 355 surrounding tobacco rod 31, but are not limited thereto. For example, the perforations 36 may transfer heat formed by the heater 210 shown in fig. 3 into the tobacco rod 31.
Likewise, second section 322 may include at least one bladder 34. Here, the pouch 34 may generate a scent. The bladder 34 may generate an aerosol. For example, the pouch 34 may have a configuration in which the liquid including the flavoring material is wrapped by a film. The bladder 34 may have a spherical or cylindrical shape, but is not limited thereto.
The first wrapper 351 may be formed by combining a conventional filter wrapper with a metal foil such as an aluminum roll. For example, the total thickness of the first wrap 351 may be in the range of 45 μm to 55 μm. For example, the total thickness of the first wrap 351 may be 50.3 μm. Further, the thickness of the metal roll of the first wrap 351 may be in the range of 6 μm to 7 μm. For example, the thickness of the metal roll of the first wrap 351 may be 6.3 μm. Further, the basis weight of the first wrapper 351 may be in the range of 50g/m2 to 55g/m 2. For example, the basis weight of the first wrapper 351 may be 53g/m2.
The second wrapper 352 and the third wrapper 353 may be formed from conventional filter wrap paper. For example, the second wrapper 352 and the third wrapper 353 may be porous wrap or non-porous wrap.

Fig. 8 is a diagram for explaining a configuration of an aerosol-generating device according to an embodiment of the present disclosure.
Referring to fig. 8, the aerosol generating device 10 may include a resistance detection sensor 150, a puff sensor 155, a battery 16, a power circuit 160, and/or a heater 210.
According to embodiments of the present disclosure, the resistance detection sensor 150, the suction sensor 155, the battery 16, and/or the power circuit 160 may be disposed in the body 100. The heater 210 may be disposed in the cartridge 200.
When the body 100 and the cartridge 200 are coupled to each other, the resistance detection sensor 150 of the body 100 may be electrically connected to the heater 210 of the cartridge 200. For example, the resistance detection sensor 150 may be a current sensor for detecting a current.
The power supply circuit 160 provided in the main body 100 may supply power to the heater 210 using power stored in the battery 16. In this case, the amount of electric power supplied from the power supply circuit 160 to the heater 210 may be adjusted under the control of the controller 17.
The power supply circuit 160 may include at least one switching element that operates under the control of the controller 17. In this case, power may be supplied to the heater 210 in response to the operation of the switching element. For example, the switching element may be a Bipolar Junction Transistor (BJT) or a Field Effect Transistor (FET).
When the heater 210 and the resistance detection sensor 150 are electrically connected to each other, a current having the same magnitude may flow through the heater 210 and the resistance detection sensor 150. Here, the resistance Rs of the shunt resistor provided in the resistance detection sensor 150 may be a value that does not change with temperature.
The controller 17 may determine the voltage V1 applied to the heater 210 and the resistance detection sensor 150 based on the power supplied from the power supply circuit 160 to the heater 210 and the current flowing through the heater 210 and the resistance detection sensor 150. The controller 17 may calculate the voltage V2 applied to the shunt resistor of the resistance detection sensor 150 based on the current flowing through the shunt resistor and the resistance Rs of the shunt resistor. In this case, the controller 17 may calculate the voltage applied to the heater 210 as the difference (V1-V2) between the voltage V1 applied to the heater 210 and the resistance detection sensor 150 and the voltage V2 applied to the shunt resistor. In addition, the controller 17 may calculate the resistance Rh of the heater 210 based on the voltage applied to the heater 210 and the current flowing through the heater 210.
Accordingly, the controller 17 can determine the temperature of the heater 210 in real time based on the current flowing through the heater 210, which is calculated by the resistance detection sensor 150 even when the core is heated by the heater 210.
Meanwhile, the resistor of the heater 210 may be a material having a temperature coefficient of resistance, and the resistance Rh of the heater 210 may vary according to a variation in the temperature of the resistor. The controller 17 may calculate the temperature of the heater 210 using a heater temperature calculation equation based on the temperature coefficient of resistance of the heater 210, the resistance Rh of the heater 210, and the resistance of the heater 210 at the reference temperature. Here, a heater temperature calculation equation for calculating the temperature of the heater 210 may be expressed using the following equation 1.
[ Equation 1]
TCR＝(R1-R0)/R0÷(T1-T0)
In the above equation 1, TCR represents the temperature coefficient of resistance of the heater 210, T1 represents the temperature of the heater 210, R1 represents the resistance of the heater 210, T0 represents the reference temperature, and R0 represents the resistance of the heater 210 at the reference temperature. Here, T0 is 25 ℃, and R0 is the resistance of the heater 210 at 25 ℃.
Although the current sensor is shown in this figure as being connected in series with the heater 210, the present disclosure is not limited thereto. A temperature sensor disposed adjacent to the heater 210 to detect the temperature of the heater 210 or a voltage sensor for detecting a voltage applied to the heater 210 may be provided as the resistance detection sensor 150.
The suction sensor 155 may output a signal corresponding to suction. For example, the suction sensor 155 may output a signal corresponding to the internal pressure of the aerosol-generating device 10. Here, the internal pressure of the aerosol-generating device 10 may correspond to the pressure in the flow path through which the gas flows. In this embodiment, the suction sensor 155 is described as being implemented as a pressure sensor configured to output a signal corresponding to the internal pressure of the aerosol-generating device 10, but the disclosure is not limited thereto.
The controller 17 may determine suction based on signals received from the suction sensor 155. For example, the controller 17 may determine whether suction occurs based on a sensed value of a signal from the suction sensor 155. For example, the controller 17 may determine the suction intensity based on a sensed value of the signal from the suction sensor 155. For example, the controller 17 may determine a period of time during which suction occurs (hereinafter referred to as a suction period) based on a sensed value of a signal from the suction sensor 155.
Upon determining that suction has occurred, the controller 17 may control the aerosol-generating module 13. For example, upon determining that suction has occurred, the controller 17 may control the aerosol-generating module 13 such that power is supplied to a heater included in the aerosol-generating module 13.
Upon determining that aspiration has occurred, the controller 17 may update the data stored in the memory 14. For example, upon determining that suction has occurred, the controller 17 may update the current number of puffs stored in the memory 14. For example, upon determining that aspiration has occurred, the controller 17 may update the data of the aspiration intensity stored in the memory 14.
Fig. 9 is a flowchart illustrating an operation method of an aerosol-generating device according to an embodiment of the present disclosure.
Referring to fig. 9, in operation S910, the aerosol-generating device 10 may detect suction using the suction sensor 155. For example, when the internal pressure value of the aerosol-generating device 10 is less than the reference pressure value, the aerosol-generating device 10 may determine that suction has occurred. For example, when the change in the internal pressure value of the aerosol-generating device 10 is equal to or greater than the minimum change, the aerosol-generating device 10 may determine that suction has occurred.
Upon detecting that suction is occurring, the aerosol-generating device 10 may heat the heater 210 in operation S920. For example, the aerosol-generating device 10 may supply power to the heater 210 based on a predetermined temperature profile stored in the memory 14 such that the temperature of the heater 210 increases to a temperature for generating an aerosol.
According to one embodiment, the power supplied to the heater 210 during the heating period may vary according to the number of times of pumping or the time elapsed during the heating period. For example, the power supplied to the heater 210 when suction is detected may decrease with the time when suction is detected.
In operation S930, the aerosol-generating device 10 may determine whether the suction is ended. For example, when the internal pressure value of the aerosol-generating device 10 is less than the reference pressure value, the aerosol-generating device 10 may determine that the puff has ended. For example, when the slope corresponding to the change in the internal pressure value of the aerosol-generating device 10 is greater than 0, the aerosol-generating device 10 may determine that the suction has ended.
In this embodiment, the period in which suction is detected by the suction sensor 155 may be referred to as a heating period or a first period. The first period may be referred to as a heating period. Meanwhile, a period in which suction is not detected (for example, a period from a point in time when suction is completed to a point in time when suction is redetected) may be referred to as a warm-up period or a second period.
In operation S940, the aerosol-generating device 10 may determine whether the suction intensity detected in the heating period exceeds a predetermined reference intensity. For example, the suction intensity in the heating period may correspond to a minimum value of the internal pressure value of the aerosol-generating device 10 detected in the heating period. For example, the suction intensity in the heating period may correspond to a maximum value of the change in the internal pressure value of the aerosol-generating device 10 detected in the heating period.
Upon determining that the suction intensity detected in the heating period is equal to or less than the predetermined reference intensity, the aerosol-generating device 10 may preheat the heater 210 using the basic power set for the preheating period in operation S950. For example, the aerosol-generating device 10 may control the power supply circuit 160 such that a predetermined basic power (e.g., 0.5W of power) is supplied to the heater 210. In this case, the target temperature of the heater 210 in the warm-up period may be set to a relatively low temperature (e.g., 140 ℃).
Meanwhile, upon determining that the suction intensity detected in the heating period exceeds the predetermined reference intensity, the aerosol-generating device 10 may preheat the heater 210 using power (hereinafter referred to as boost power) higher than the basic power set for the preheating period in operation S960. For example, the aerosol-generating device 10 may control the power supply circuit 160 such that 1.0W of power higher than the base power (i.e., 0.5W) is supplied to the heater 210. In this case, the target temperature of the heater 210 may be set to a relatively high temperature (e.g., 200 ℃) in the warm-up period.
According to one embodiment, the aerosol-generating device 10 may determine the boost power based on a difference between the detected suction intensity and the reference intensity in the heating period. For example, when the suction intensity detected in the heating period exceeds the reference intensity, the aerosol-generating device 10 may determine the electric power higher than the basic electric power by a predetermined level as the boosting electric power. In this case, the difference between the boost power and the basic power may be proportional to the difference between the suction intensity detected in the heating period and the reference intensity. That is, when the user inhales the aerosol more strongly in the heating period, the amount of boosting voltage supplied to the heater 210 in the preheating period may increase.
When the amount of the aerosol-generating substance contained in the liquid delivery unit is relatively large, the temperature of the aerosol-generating substance may rise relatively slowly when the heater 210 is heated. Further, when the temperature of the aerosol-generating substance increases relatively slowly, the amount of aerosol supplied to the user can be reduced. On the other hand, when the amount of aerosol supplied from the aerosol-generating device 10 is relatively small, the user can inhale the aerosol relatively strongly so as to inhale a sufficient amount of aerosol. In this case, the aerosol-generating device 10 may increase the power supplied to the heater 210 in the warm-up period based on the inhalation intensity of the user, thereby increasing the amount of aerosol supplied to the user in the warm-up period.
Referring to fig. 10 and 11, the aerosol-generating device 10 may determine that suction has occurred at time points t1, t3, and t5 at which the internal pressure value corresponding to the signal from the suction sensor 155 is smaller than Pr1 as the reference pressure value. In addition, the aerosol-generating device 10 may determine that the suction has ended at time points t2, t4, and t6 at which the internal pressure value corresponding to the signal from the suction sensor 155 is equal to or greater than Pr1 as the reference pressure value.
In this case, the period from the time point t1 to the time point t2 may be a first heating period, the period from the time point t3 to the time point t4 may be a second heating period, and the period from the time point t5 to the time point t6 may be a third heating period. In addition, the period before the time point t1 may be the first warm-up period, the period from the time point t2 to the time point t3 may be the second warm-up period, the period from the time point t4 to the time point t5 may be the third warm-up period, and the period after the time point t6 may be the fourth warm-up period.
When suction is detected in the first to third heating periods, the aerosol-generating device 10 may supply the electric power P1 to the heater 210. In the first to third heating periods, the minimum value of the internal pressure value corresponding to the signal from the suction sensor 155 may be equal to or greater than Pr2, pr2 being the internal pressure value corresponding to the reference intensity. In this case, the aerosol-generating device 10 may determine that all the suction intensities detected in the first to third heating periods are equal to or less than the reference intensity.
Upon determining that all the suction intensities detected in the first to third heating periods are equal to or less than the reference intensity, the aerosol-generating device 10 may supply the electric power P0 as the basic electric power to the heater 210 in the second to fourth preheating periods.
Meanwhile, referring to fig. 12 and 13, in the first heating period and the second heating period, the minimum value of the internal pressure value corresponding to the signal from the suction sensor 155 may be smaller than Pr2, pr2 being the internal pressure value corresponding to the reference intensity. In this case, the aerosol-generating device 10 may determine that all of the suction intensities detected in the first heating period and the second heating period exceed the reference intensity.
Upon determining that all the suction intensities detected in the first heating period and the second heating period exceed the reference intensity, the aerosol-generating device 10 may supply electric power P2 higher than electric power P0 as the basic electric power to the heater 210 in the second preheating period and the third preheating period. In this case, the power P2 as the boost power may be higher than the power P0 as the basic power, and may be lower than or equal to the power P1 as the power supplied to the heater 210 in the heating period.
Meanwhile, in the third heating period, the minimum value of the internal pressure value corresponding to the signal from the suction sensor 155 may be equal to or greater than Pr2, pr2 being the internal pressure value corresponding to the reference intensity. In this case, the aerosol-generating device 10 may determine that the suction intensity detected in the third heating period is equal to or less than the reference intensity. Upon determining that the suction intensity detected in the third heating period is equal to or less than the reference intensity, the aerosol-generating device 10 may supply the electric power P0 as the basic electric power to the heater 210 in the fourth warm-up period.
Fig. 14A and 14B are flowcharts illustrating an operation method of an aerosol-generating device according to another embodiment of the present disclosure. A detailed description of the same contents as those described with reference to fig. 9 to 13 will be omitted.
Referring to fig. 14A, in operation S1401, the aerosol-generating device 10 may determine whether the aerosol-generating device 10 is powered on. For example, the aerosol-generating device 10 may be powered on upon receiving a user input for powering the aerosol-generating device 10 through the input device. For example, the aerosol-generating device 10 may be energized in response to insertion of the rod 20 into the insertion spaces 130 and 230 (which is detected by the rod detection sensor).
In operation S1402, the aerosol-generating device 10 may determine whether a predetermined period of time has elapsed from a point in time when the supply of power to the heater 210 is interrupted. For example, the amount of aerosol-generating substance contained in the liquid delivery unit may continuously increase from the point in time when aerosol generation is completed. Therefore, when a predetermined period of time or more has elapsed from the point in time when aerosol generation is completed, the amount of aerosol-generating substance contained in the liquid delivery unit may be too large.
Upon determining that the predetermined period of time has not elapsed since the point in time when the supply of power to the heater 210 is interrupted, the aerosol-generating device 10 may preheat the heater 210 using the basic power set for the preheating period in operation S1403.
In operation S1404, the aerosol-generating device 10 may determine whether the puff sensor 155 detects a puff.
Upon determining that suction is detected, the aerosol-generating device 10 may heat the heater 210 in operation S1405.
In operation S1406, the aerosol-generating device 10 may determine whether the suction is ended. When the suction is detected, the aerosol-generating device 10 may supply power to the heater 210 based on a predetermined temperature profile stored in the memory 14.
In operation S1407, the aerosol-generating device 10 may determine whether the aerosol-generating device 10 is powered off. For example, the aerosol-generating device 10 may be powered down upon receiving a user input for powering down the aerosol-generating device 10 via the input device. For example, the aerosol-generating device 10 may be powered down in response to removal of the rod 20 from the insertion spaces 130 and 230 as detected by the rod detection sensor. For example, the aerosol-generating device 10 may power down the aerosol-generating device 10 when it is determined that the number of puffs detected after power-on is equal to or greater than the maximum number of puffs.
When suction is not detected in a state where the aerosol-generating device 10 is energized, the aerosol-generating device 10 may preheat the heater 210 using the basic power set for the preheating period.
Meanwhile, referring to fig. 14B, when it is determined that a predetermined period of time or more has elapsed since the point in time when the supply of power to the heater 210 is interrupted, the aerosol-generating device 10 may preheat the heater 210 using the basic power set for the preheating period in operation S1408.
In operation S1409, the aerosol-generating device 10 may determine whether the puff sensor 155 detects a puff.
Upon determining that suction is detected, the aerosol-generating device 10 may heat the heater 210 in operation S1410.
In operation S1411, the aerosol-generating device 10 may determine whether the suction is ended. When the suction is detected, the aerosol-generating device 10 may supply power to the heater 210 based on a predetermined temperature profile stored in the memory 14.
In operation S1412, the aerosol-generating device 10 may determine whether the aerosol-generating device 10 is powered off.
Upon determining that the suction has ended, the aerosol-generating device 10 may determine whether a predetermined reference intensity is present in operation S1413.
Upon determining that the predetermined reference intensity does not exist, the aerosol-generating device 10 may add the suction intensity detected in the heating period to the data of the suction intensity stored in the memory 14 in operation S1414.
According to one embodiment, the aerosol-generating device 10 may determine the reference intensity based on whether a predetermined condition corresponding to the puff is satisfied. Here, the predetermined condition corresponding to the suction may be whether the number of times of suction detected in the cartridge 200 is equal to or greater than a predetermined number of times. For example, when the number of puffs detected after coupling the cartridge 200 to the body 100 is less than a predetermined number (e.g., 10), the aerosol-generating device 10 may store the intensity of puffs in the memory 14 in response to the detection of puffs. For example, when the number of times of suction detected after coupling the cartridge 200 to the main body 100 is equal to or greater than a predetermined number of times (for example, 10 times), the aerosol generating device 10 may set the reference intensity based on the data of the suction intensity stored in the memory 14. In this case, the aerosol-generating device 10 may set the representative value of the plurality of intensity values included in the data of the suction intensity stored in the memory 14 as the reference intensity.
