For example, the memory (1400) may store application programs designed for the purpose of performing various tasks that can be processed by the control unit (1700), and may selectively provide some of the stored application programs upon request from the control unit (1700).

For example, the memory (1400) may store data on the operation time of the aerosol generating device (1000), the maximum number of puffs, the current number of puffs, at least one temperature profile, and the user's inhalation pattern. Here, a puff may mean an inhalation by the user, and an inhalation may mean a situation in which the user draws air into the user's oral cavity, nasal cavity, or lungs through the mouth or nose.

The memory (1400) may include at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) or non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).

The memory (1400) may be arranged in at least one of the body (100), the cartridge (200), and the cap (300). The memory (1400) may be arranged in each of the body (100) and the cartridge (200).

The sensor module (1500) may include at least one sensor.

For example, the sensor module (1500) may include a sensor that detects a puff (hereinafter, a puff sensor), for example, a second sensor (180, see FIG. 2). At this time, the puff sensor may be implemented by a proximity sensor such as an IR sensor, a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, etc.

For example, the sensor module (1500) may include a sensor (hereinafter, temperature sensor) that detects the temperature of the heater (262) included in the aerosol generating module (1300), the temperature of the aerosol generating material, etc.

At this time, the heater (262) included in the aerosol generating module (1300) may also function as a temperature sensor. For example, the electrically resistive material of the heater (262) may be a material having a temperature coefficient of resistance (TCR), and the sensor module (1500) may sense the temperature of the heater (262) by measuring the resistance of the heater (262) that varies depending on the temperature.

For example, if a stick can be inserted into the body (100) and/or cartridge (200) of the aerosol generator (1000), the sensor module (1500) may include a sensor that detects the insertion of the stick (hereinafter, a stick detection sensor).

For example, if the aerosol generator (1000) includes a cartridge (200), the sensor module (1500) may include a sensor (hereinafter, cartridge detection sensor) that detects mounting/detaching, position, etc. of the cartridge (200) with respect to the body (100).

At this time, the stick detection sensor and/or the cartridge detection sensor may be implemented by an inductance-based sensor, a capacitance sensor, a resistance sensor, a Hall sensor using the Hall effect, etc. According to one embodiment of the present invention, the first sensor (154, see FIG. 17) may be configured as a stick detection sensor. Meanwhile, according to one embodiment of the present invention, the cartridge detection sensor may include a first connection terminal (191, see FIG. 21).

For example, the sensor module (1500) may include a voltage sensor for detecting voltage applied to a component (e.g., battery (1600)) provided in the aerosol generator (1000) and/or a current sensor for detecting current.

The battery (1600) can supply power used for the operation of the aerosol generator (1000) under the control of the control unit (1700). The battery (1600) can supply power to other components provided in the aerosol generator (1000), such as a communication module included in the communication interface (1100), an output device included in the input/output interface (1200), a heater (262) included in the aerosol generator module (1300), etc. For example, the battery (1600) can be a battery (190) accommodated inside the lower body (110).

The battery (1600) may be a rechargeable battery or a disposable battery. For example, the battery (1600) may be composed of, but is not limited to, a lithium-ion battery, a lithium polymer (Li-Polymer) battery, a lithium iron phosphate (Lithium-ion Phosphate) battery, etc. For example, the battery (1600) may be composed of, but is not limited to, a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, etc.

The aerosol generator (1000) may further include a battery protection module (PCM), which is a circuit for protecting the battery (1600). The battery protection module (PCM) may be arranged adjacent to the upper surface of the battery (1600). For example, the battery protection module (PCM) may block the electric path to the battery (1600) in the event of a short circuit in a circuit connected to the battery (1600), in the event of overvoltage being applied to the battery (1600), in the event of overcurrent flowing to the battery (1600), etc., in order to prevent overcharge and overdischarge of the battery (1600).

The aerosol generator (1000) may further include a charging terminal into which power supplied from the outside is input. For example, a charging terminal (e.g., charging port (119, see FIG. 2)) may be formed on one side of the body (100) of the aerosol generator (1000), and the aerosol generator (1000) may charge the battery (1600) using power supplied through the charging terminal. At this time, the charging terminal may be configured as a wired terminal for USB communication, a pogo pin, or the like.

The aerosol generator (1000) may also wirelessly receive power supplied from an external source through a communication interface (1100). For example, the aerosol generator (1000) may wirelessly receive power using an antenna included in a communication module for wireless communication, and may charge a battery (1600) using the wirelessly supplied power.

The control unit (1700) can control the overall operation of the aerosol generating device (1000). For example, the control unit (1700) can include a control device (193) accommodated inside the lower body (110).

The control unit (1700) can be connected to each component provided in the aerosol generating device (1000), and can control the overall operation of each component by transmitting and/or receiving signals between each component.

The control unit (1700) may include at least one processor, and may control the overall operation of the aerosol generating device (1000) using the processor included therein. Here, the processor may be a general processor such as a central processing unit (CPU). Of course, the processor may be a dedicated device such as an ASIC or another hardware-based processor.

The control unit (1700) can perform any one of the multiple functions of the aerosol generator (1000). For example, the control unit (1700) can perform any one of the multiple functions of the aerosol generator (1000) (e.g., preheating function, heating function, charging function, cleaning function, etc.) according to the status of each component provided in the aerosol generator (1000), a user command received through the input/output interface (1200), etc.

The control unit (1700) can control the operation of each component provided in the aerosol generating device (1000) based on data stored in the memory (1400). For example, the control unit (1700) can control a predetermined power to be supplied from the battery (1600) to the aerosol generating module (1300) for a predetermined period of time based on data on a temperature profile, a user's inhalation pattern, etc. stored in the memory (1400).

The control unit (1700) can determine whether a puff is present through the puff sensor included in the sensor module (1500). For example, the control unit (1700) can check temperature changes, flow changes, pressure changes, voltage changes, etc. within the aerosol generating device (1000) based on the sensing values of the puff sensor, and can determine whether a puff is present based on the checked results.

The control unit (1700) can control the operation of each component provided in the aerosol generating device (1000) depending on whether a puff is made and/or the number of puffs. For example, the control unit (1700) can control the temperature of the heater (262) to be changed or maintained based on the temperature profile stored in the memory (1400).

The control unit (1700) can control power supply to the heater (262) to be cut off according to a predetermined condition. For example, when the stick (400) is removed from the insertion space (214), when the cartridge (200) is separated from the body (100), when the number of puffs reaches a preset maximum number of puffs, when no puffs are detected for a preset time or longer, when the remaining capacity of the battery (1600) is less than a preset value, etc., the control unit (1700) can control power supply to the heater (262) to be cut off.

The control unit (1700) can calculate the remaining capacity of the power stored in the battery (1600). For example, the control unit (1700) can calculate the remaining capacity of the battery (1600) based on the sensing values of the voltage sensor and/or the current sensor included in the sensor module (1500).

The control unit (1700) can control power to be supplied to the heater (262) using at least one of a pulse width modulation (PWM) method and a proportional-integral-differential (PID) method.

For example, the control unit (1700) can control a current pulse having a predetermined frequency and duty ratio to be supplied to the heater (262) using the PWM method. At this time, the control unit (1700) can control the power supplied to the heater (262) by adjusting the frequency and duty ratio of the current pulse.

For example, the control unit (1700) can determine a target temperature that is a target of control based on a temperature profile. At this time, the control unit (1700) can control the power supplied to the heater (262) by using a PID method, which is a feedback control method using a difference value between the temperature of the heater (262) 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.

Meanwhile, the PWM method and the PID method have been described as examples of control methods for supplying power to the heater (262), but the present invention is not limited thereto, and various control methods such as the Proportional-Integral (PI) method and the Proportional-Differential (PD) method can be used.

Meanwhile, the aerosol generator (1000) may further include a power supply circuit (not shown) that transmits power stored in the battery (190) to the heater (262). At this time, the power supplied to the heater (262) through the power supply circuit may be regulated according to the control of the control unit (1700).

The power supply circuit may include at least one switching element that operates under the control of the control unit (1700). At this time, power may be supplied to the heater (262) according 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).

FIGS. 28 and 29 are flowcharts illustrating an operation method of an aerosol generating device according to one embodiment of the present disclosure.

Referring to FIG. 28, the aerosol generating device (1000) can monitor whether the stick (400) is inserted into the insertion space (214) in operation S2810. For example, the aerosol generating device (1000) can monitor whether the stick (400) is inserted into the insertion space (214) through the first sensor (154) while the stick (400) is removed from the insertion space (214).

Meanwhile, when the aerosol generator (1000) is turned on while the stick (400) is inserted into the insertion space (214), it may be determined that the stick (400) is inserted into the insertion space (214).

The aerosol generator (1000) can check the remaining capacity of power (hereinafter, “remaining power”) stored in the battery (1600) when the stick (400) is inserted into the insertion space (214) in operation S2820. For example, the aerosol generator (1000) can calculate the remaining power of the battery (1600) in response to the output voltage of the battery (1600).

The aerosol generator (1000) can determine, in operation S2830, whether the remaining power of the battery (1600) is less than the reference power corresponding to the stick (400). Here, the reference power can correspond to the power consumed while the user uses one stick (400) according to the preset number of puffs (e.g., 14 times).

The aerosol generator (1000) may, in operation S2840, cut off the supply of power to the heater (262) if the remaining power of the battery (1600) is less than the reference power. For example, if the current remaining power of the battery (1600) is 40% of the maximum power stored in the battery (1600) and the reference power is 45% of the maximum power, the aerosol generator (1000) may set the duty ratio of the current pulse supplied to the heater (262) to 0%.

Meanwhile, the aerosol generator (1000) can supply power to the heater (262) when the remaining power of the battery (1600) is greater than the reference power in operation S2850. In this regard, a detailed description will be given with reference to FIG. 29.

Referring to FIG. 29, the aerosol generator (1000) may supply power to the heater (262) based on the temperature profile in operation S2910. For example, the aerosol generator (1000) may determine the target temperature of the heater (262) corresponding to the current number of puffs based on the temperature profile. At this time, the aerosol generator (1000) may supply power to the heater (262) so that the temperature of the heater (262) corresponds to the target temperature.

Referring to FIG. 30, if the remaining power amount of the battery (1600) is less than the reference power amount at time t0 when the stick (400) is inserted into the insertion space (214), the aerosol generator (1000) can supply power P0 to the heater (262) until time t1 according to the temperature profile. At this time, the temperature of the heater (262) can rise to the target temperature (e.g., 150°C) for generating the aerosol.

The period from time t0 to time t1 can be named the initial warm-up period.

The aerosol generator (1000) can supply power P1 lower than power P0 to the heater (262) from time t1 according to the temperature profile. At this time, the temperature of the heater (262) can be maintained at a certain temperature (e.g., 100°C) lower than the temperature for generating the aerosol (e.g., 160°C). Meanwhile, the aerosol generator (1000) can monitor whether a puff is detected through the puff sensor from time t1.

The aerosol generator (1000) can supply power P2 higher than power P1 to the heater (262) from the time point t2 when a puff is detected through the puff sensor. At this time, the temperature of the heater (262) can rise to a temperature (e.g., 150° C.) or higher for generating an aerosol.

The aerosol generator (1000) can reduce the power supplied to the heater (262) from the time point t3 according to a predetermined condition. For example, the aerosol generator (1000) can supply power P1 to the heater (262) when the puff is terminated at the time point t3. For example, the aerosol generator (1000) can supply power P1 to the heater (262) when the temperature of the heater (262) is equal to or higher than a preset limit temperature (e.g., 160° C.) at the time point t3.

The section from time t1 to time t3 may be named as the first puff section (Puff 1). Similarly, the section from time t3 to time t5 may be named as the second puff section (Puff 2). In addition, if the preset number of puffs for one stick (400) is 14, the last puff section may be named as the 14th puff section (Puff 14).

Meanwhile, the aerosol generator (1000) can cut off the power supply to the heater (262) from time t8 when the 14th puff section (Puff 14) ends.

In this drawing, the amount of power supplied to the heater (262) is shown as being constant for each puff section, but the present invention is not limited thereto. For example, when a puff is detected, the power supplied to the heater (262) may vary depending on the puff section.

Referring again to FIG. 29, the aerosol generator (1000) can determine, in operation S2920, whether the current number of puffs is less than the preset number of puffs. At this time, the aerosol generator (1000) can cut off the power supply to the heater (262) if the current number of puffs is greater than or equal to the preset number of puffs.

The aerosol generator (1000) can determine, in operation S2930, whether the remaining power of the battery (1600) is equal to or greater than the preset minimum power amount. Here, the minimum power amount may be the minimum value of the power amount required to heat the heater (262) for generating the aerosol. At this time, the aerosol generator (1000) can cut off the power supply to the heater (262) if the remaining power amount of the battery (1600) is less than the preset minimum power amount.

The aerosol generator (1000) can determine, in operation S2940, whether the stick (400) is removed from the insertion space (214). For example, the aerosol generator (1000) can monitor, through the first sensor (154), whether the stick (400) is removed from the insertion space (214) while the stick (400) is inserted into the insertion space (214). At this time, the aerosol generator (1000) can cut off the power supply to the heater (262) when the stick (400) is removed from the insertion space (214).

The aerosol generator (1000) can determine, in operation S2950, whether a puff is not detected for a predetermined period of time or longer based on the sensing value of the puff sensor. For example, the aerosol generator (1000) can monitor whether a puff is detected through the puff sensor while maintaining the temperature of the heater (262) at a constant temperature level according to the temperature profile while the current number of puffs is less than the preset number of puffs, which is 14. At this time, if the puff is not detected for 5 minutes, which is set as the preset period of time, the aerosol generator (1000) can cut off the power supply to the heater (262).

The aerosol generator (1000), in operation S2960, can maintain the currently set reference power amount when the stick (400) is removed from the insertion space (214) or no puffs are detected for a predetermined period of time while the current number of puffs is less than the preset number of puffs. For example, when the current number of puffs is less than the preset number of puffs, 14 times, and the remaining power of the battery (1600) is sufficient, the user can remove the stick (400) from the insertion space (214) or stop inhaling the aerosol for a predetermined period of time, 5 minutes or more. In this case, since one stick (400) is not used for the preset number of puffs, there is not enough data for updating the reference power amount, so the update of the reference power amount may be omitted.

Meanwhile, the aerosol generator (1000) can update the currently set reference power amount in operation S2970. For example, the aerosol generator (1000) can change the preset reference power amount stored in the memory (1400) to the power amount determined as the new reference power amount.

According to one embodiment, the aerosol generator (1000) may update the reference power amount based on the degree to which the remaining power amount of the battery (1600) has decreased when the current number of puffs is greater than or equal to a preset number of puffs. For example, when the preset number of puffs is 14, the aerosol generator (1000) may determine the degree to which the remaining power amount of the battery (1600) has decreased during the time from the time the stick (400) is inserted into the insertion space (214) to the time the 14th puff section ends as the new reference power amount.

According to one embodiment, the aerosol generator (1000) can update the reference power amount based on the power consumed per puff when the current number of puffs is greater than or equal to a preset number of puffs.

Referring to FIG. 30, the aerosol generator (1000) can calculate the amount of power supplied to the heater (262) from time t1 to time t3 as the amount of power consumed in the first puff section (Puff 1). Similarly, the aerosol generator (1000) can calculate the amount of power consumed in each of the second puff section (Puff 2) to the fourteenth puff section (Puff 14).

At this time, the aerosol generator (1000) may determine a new reference power amount as the sum of a product of a representative value of the amount of power consumed per puff and a preset number of puffs, a total amount of power supplied to the heater (262) in the initial preheating section, and a total amount of power supplied to the remaining components excluding the heater (262) from time t0 to time t8. Here, the representative value of the amount of power consumed per puff may be any one of an average value, a mode, and a maximum value of the amount of power consumed per puff, but the present invention is not limited thereto. For example, the representative value of the amount of power consumed per puff may be a maximum value of the amount of power consumed per puff.

According to one embodiment, the aerosol generator (1000) may update the reference power amount based on the difference between the preset number of puffs and the current number of puffs when the current number of puffs is less than the preset number of puffs and the remaining power amount of the battery (1600) is less than the preset minimum power amount. For example, when the preset number of puffs is 14 and the current number of puffs is 13, the aerosol generator (1000) may determine the power amount that is the current preset reference power amount plus the power amount corresponding to one puff as the new reference power amount.

At this time, the amount of power corresponding to one puff can be determined based on a preset amount of power, a representative value of the amount of power consumed per puff, etc. For example, the amount of power corresponding to one puff can be greater than or equal to the maximum value of the amount of power consumed per puff.

Meanwhile, the aerosol generator (1000) can update the reference power amount based on the power amount determined as the new reference power amount and at least one power amount previously set as the reference power amount. For example, the aerosol generator (1000) can set the average value of two power amounts recently set among the power amount determined as the new reference power amount and the power amount set as the reference power amount.

At this time, the aerosol generator (1000) can calculate an average value based on the result of assigning weights to each power amount, similar to the following mathematical expression 1. At this time, the weights can be assigned differently according to the order set as the reference power amount.

For example, the average value of power (Pavg) can be calculated based on the first power (P1) determined as the new reference power, the second power (P2) set as the reference power just before, and the third power (P3) set as the reference power before the second power (P2). At this time, the power determined as the new reference power can be given the greatest weight.

As described above, according to at least one of the embodiments of the present disclosure, the efficiency of gas flow can be improved, thereby improving the heat transfer efficiency of the aerosol to the stick (400).

According to at least one embodiment of the present disclosure, it is possible to prevent the power supply of the battery (1600) from being interrupted before the user's use of the stick is completed.

According to at least one embodiment of the present disclosure, the amount of power required for a user's use of the stick can be optimized by taking into account the user's suction pattern.
