<1. Configuration example of suction device>
A suction device is a device that produces a substance that is suctioned by a user. In the following description, it is assumed that the substance produced by the suction device is an aerosol. Alternatively, the substance produced by the suction device may be a gas.

FIG. 1 is a schematic diagram schematically showing a configuration example of a suction device. As shown in FIG. 1, the suction device 100 according to this configuration example includes a power supply unit 111, a sensor unit 112, a notification unit 113, a storage unit 114, a communication unit 115, a control unit 116, a heating unit 121, a holding unit 140, and Insulation 144 is included.

The power supply unit 111 accumulates power. The power supply unit 111 supplies electric power to each component of the suction device 100 under the control of the control unit 116 . The power supply unit 111 may be composed of, for example, a rechargeable battery such as a lithium ion secondary battery.

As an example, the sensor unit 112 is configured by a pressure sensor such as a condenser microphone, a flow rate sensor, a temperature sensor, or the like, and acquires a value associated with suction by the user. As another example, the sensor unit 112 is configured by an input device, such as a button or switch, that receives information input from the user.

The notification unit 113 notifies the user of information. The notification unit 113 is configured by, for example, a light emitting device that emits light, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates.

The storage unit 114 stores various information for the operation of the suction device 100 . The storage unit 114 is configured by, for example, a non-volatile storage medium such as flash memory.

The communication unit 115 is a communication interface capable of performing communication conforming to any wired or wireless communication standard. As such a communication standard, for example, Wi-Fi (registered trademark) or bluetooth (registered trademark) can be adopted.

The control unit 116 is realized by an electronic circuit such as a CPU (Central Processing Unit) and a microprocessor.

The holding part 140 has an internal space 141 and holds the stick-shaped base material 150 while accommodating a part of the stick-shaped base material 150 in the internal space 141 . The holding part 140 has an opening 142 that communicates the internal space 141 with the outside, and holds the stick-shaped substrate 150 inserted into the internal space 141 through the opening 142 . For example, the holding portion 140 is a cylindrical body having an opening 142 and a bottom portion 143 as a bottom surface, and defines a columnar internal space 141 . An air flow path for supplying air to the internal space 141 is connected to the holding portion 140 . An air inlet hole, which is an inlet of air to the air flow path, is arranged on the side surface of the suction device 100, for example. Air outflow holes, which are outlets for air from the air flow path to the internal space 141 , are arranged, for example, in the bottom portion 143 .

The stick-type base material 150 includes a base material portion 151 and a mouthpiece portion 152 . Substrate portion 151 includes an aerosol source. Aerosol sources are, for example, polyhydric alcohols such as glycerin and propylene glycol, and liquids such as water. The aerosol source may contain tobacco-derived or non-tobacco-derived flavoring ingredients. If the inhalation device 100 is a medical inhaler, such as a nebulizer, the aerosol source may contain a medicament. In addition, in this configuration example, the aerosol source is not limited to liquid, and may be solid. When the stick-shaped base material 150 is held by the holding part 140 , at least part of the base material part 151 is accommodated in the internal space 141 and at least part of the mouthpiece part 152 protrudes from the opening 142 . When the user sucks the mouthpiece 152 protruding from the opening 142, air flows into the internal space 141 through an air flow path (not shown) and reaches the user's mouth together with the aerosol generated from the base material 151. do.

The heating unit 121 heats the aerosol source to atomize the aerosol source and generate an aerosol. In the example shown in FIG. 1 , the heating section 121 is configured in a film shape and arranged so as to cover the outer circumference of the holding section 140 . Then, when the heating part 121 generates heat, the base material part 151 of the stick-type base material 150 is heated from the outer periphery, and an aerosol is generated. The heating unit 121 generates heat when supplied with power from the power supply unit 111 . As an example, power may be supplied when the sensor unit 112 detects that the user has started sucking and/or that predetermined information has been input. Then, the power supply may be stopped when the sensor unit 112 detects that the user has finished sucking and/or that predetermined information has been input.

The heat insulation part 144 prevents heat transfer from the heating part 121 to other components. For example, the heat insulating part 144 is made of a vacuum heat insulating material, an airgel heat insulating material, or the like.

The configuration example of the suction device 100 has been described above. Of course, the configuration of the suction device 100 is not limited to the above, and various configurations exemplified below can be adopted.

As an example, the heating part 121 may be configured in a blade shape and arranged to protrude from the bottom part 143 of the holding part 140 into the internal space 141 . In that case, the blade-shaped heating part 121 is inserted into the base material part 151 of the stick-shaped base material 150 and heats the base material part 151 of the stick-shaped base material 150 from the inside. As another example, the heating part 121 may be arranged to cover the bottom part 143 of the holding part 140 . Further, the heating unit 121 is a combination of two or more of the first heating unit that covers the outer periphery of the holding unit 140, the blade-like second heating unit, and the third heating unit that covers the bottom part 143 of the holding unit 140. may be configured as

As another example, the holding part 140 may include an opening/closing mechanism such as a hinge that opens/closes a portion of the outer shell that forms the internal space 141 . The holding part 140 may hold the stick-shaped base material 150 inserted into the internal space 141 by opening and closing the outer shell. In that case, the heating part 121 may be provided at the holding part 140 at the holding part 140 and heat the stick-shaped base material 150 while pressing it.

The stick-type substrate 150 is an example of a substrate that contains an aerosol source and contributes to the generation of aerosol. Also, the aerosol is generated by the combination of the suction device 100 and the stick-shaped substrate 150 . As such, the combination of suction device 100 and stick-type substrate 150 may be viewed as an aerosol generating system.

<2. System configuration>
FIG. 2 is a diagram showing an example of the configuration of the system 1 according to one embodiment of the invention. As shown in FIG. 2 , system 1 includes suction device 100 and terminal device 200 . The configuration of the suction device 100 is as described above.

The terminal device 200 is a device used by the user of the suction device 100.

<3. Technical features>
(1) Heating profile The control unit 116 controls the operation of the heating unit 121 based on the heating profile. Control of the operation of the heating unit 121 is realized by controlling power supply from the power supply unit 111 to the heating unit 121 . The heating unit 121 heats the stick-shaped substrate 150 using power supplied from the power supply unit 111 . A heating profile is information that defines the time-series transition of the target value of the temperature of the heating unit 121 . A heating profile is an example of a heating setting in this embodiment.

The control unit 116 controls the operation of the heating unit 121 so that the temperature of the heating unit 121 (hereinafter also referred to as the actual temperature) changes in the same manner as the target temperature specified in the heating profile. The heating profile is typically designed to optimize the flavor experienced by the user when the user inhales the aerosol produced from the stick-shaped substrate 150 . Therefore, by controlling the operation of the heating unit 121 based on the heating profile, it is possible to optimize the flavor tasted by the user.

A heating profile includes one or more combinations of a target temperature and information indicating the timing at which the target temperature should be reached. Then, the control unit 116 controls the temperature of the heating unit 121 while switching the target temperature according to the lapse of time from the start of heating based on the heating profile. Specifically, the control unit 116 controls the temperature of the heating unit 121 based on the deviation between the current actual temperature and the target temperature corresponding to the elapsed time from the start of heating based on the heating profile. Temperature control of the heating unit 121 can be realized by, for example, known feedback control. Feedback control may be, for example, PID control (Proportional-Integral-Differential Controller). The control unit 116 can cause power from the power supply unit 111 to be supplied to the heating unit 121 in the form of pulses by pulse width modulation (PWM) or pulse frequency modulation (PFM). In that case, the control unit 116 can control the temperature of the heating unit 121 by adjusting the duty ratio or frequency of the power pulse in feedback control. Alternatively, control unit 116 may perform simple on/off control in feedback control. For example, the control unit 116 performs heating by the heating unit 121 until the actual temperature reaches the target temperature, and stops heating by the heating unit 121 when the actual temperature reaches the target temperature. When the temperature becomes low, heating by the heating unit 121 may be performed again. In addition, control section 116 may adjust the voltage in feedback control.

The temperature of the heating unit 121 can be quantified by, for example, measuring or estimating the electrical resistance of the heating unit 121 (more precisely, the heating resistor that constitutes the heating unit 121). This is because the electrical resistance value of the heating resistor changes according to the temperature. The electrical resistance value of the heating resistor can be estimated, for example, by measuring the amount of voltage drop in the heating resistor. The amount of voltage drop across the heating resistor can be measured by a voltage sensor that measures the potential difference applied to the heating resistor. In another example, the temperature of heating unit 121 can be measured by a temperature sensor such as a thermistor installed near heating unit 121 .

A period from the start to the end of the process of generating an aerosol using the stick-shaped base material 150 is hereinafter also referred to as a heating session. In other words, a heating session is a period during which power supply to the heating unit 121 is controlled based on the heating profile. The beginning of the heating session is the timing at which heating based on the heating profile is started. The end of the heating session is when a sufficient amount of aerosol is no longer produced. The heating session includes a first half preheating period and a second half puffable period. The puffable period is the period during which a sufficient amount of aerosol is assumed to be generated. The preheating period is the period from the start of heating to the start of the puffable period. Heating performed in the preheating period is also referred to as preheating.

A heating profile may include multiple periods in which different target temperatures are set. The temperature may be controlled so as to reach the target temperature set for a certain period at any timing during the period, or the temperature may be controlled so as to reach the end of the period. In any case, it is possible to change the temperature of the heating unit 121 in the same manner as the target temperature defined in the heating profile.

An example of a heating profile is shown in Table 1 below.

The transition of the temperature of the heating unit 121 when the control unit 116 performs temperature control according to the heating profile shown in Table 1 will be described with reference to FIG. FIG. 3 is a graph showing an example of transition of the temperature of the heating unit 121 when temperature control is performed based on the heating profile shown in Table 1. In FIG. The horizontal axis of this graph is time (seconds). The vertical axis of this graph is the temperature of the heating unit 121 . A line 21 in this graph indicates transition of the temperature of the heating unit 121 . As shown in FIG. 3, the temperature of the heating unit 121 transitions in the same manner as the target temperature defined in the heating profile.

As shown in Table 1, the heating profile first includes an initial heating period. The initial temperature rising period is a period during which the temperature of the heating unit 121 rises from the initial temperature. The initial temperature is the temperature of the heating unit 121 at the start of heating. As shown in FIG. 3, in the initial heating period, the temperature of the heating unit 121 reaches 310° C. 17 seconds after the start of heating and is maintained at 310° C. until 35 seconds after the start of heating. As a result, it is assumed that the temperature of the stick-type substrate 150 reaches a temperature at which a sufficient amount of aerosol is generated. By rapidly raising the temperature to 310° C. immediately after the start of heating, it is possible to finish preheating early and start the puffable period early. Note that in FIG. 3, the preheating period ends 17 seconds after the start of heating.

As shown in Table 1, the heating profile includes an intermediate temperature decrease period after the initial temperature increase period. The intermediate temperature drop period is a period during which the temperature of the heating unit 121 is lowered. As shown in FIG. 3, during the mid-temperature drop period, the temperature of the heating unit 121 drops from 310° C. to 260° C. from 35 seconds to 45 seconds after the start of heating. During this period, power supply to the heating unit 121 may be stopped. Even in that case, a sufficient amount of aerosol is generated by the residual heat of the heating part 121 and the stick-shaped base material 150 . Here, if the heating unit 121 is kept at a high temperature, the aerosol source contained in the stick-shaped base material 150 is rapidly consumed, and the flavor deteriorates such that the flavor tasted by the user becomes too strong. In this regard, by providing an intermediate temperature-lowering period in the middle, it is possible to avoid such flavor deterioration and improve the quality of the user's puff experience.

As shown in Table 1, the heating profile includes a reheating period after an intermediate temperature decreasing period. The reheating period is a period during which the temperature of the heating unit 121 increases. As shown in FIG. 3, in the reheating period, the temperature of the heating unit 121 rises from 260° C. to 290° C. from 45 seconds to 180 seconds after the start of heating, and reaches 290° C. until 260 seconds after the start of heating. maintained at If the temperature of the heating part 121 is continued to be lowered, the temperature of the stick-shaped base material 150 is also lowered, so the amount of aerosol generated is reduced, and the flavor that the user can enjoy may be deteriorated. In addition, as the heating profile progresses to the latter half, the remaining amount of the aerosol source contained in the stick-type substrate 150 decreases, so even if the heating is continued at the same temperature, the amount of aerosol generated tends to decrease. In this regard, by raising the temperature again in the second half of the heating profile to increase the amount of aerosol generated, it is possible to compensate for the decrease in the amount of aerosol generated due to the decrease in the remaining amount of the aerosol source. This makes it possible to prevent the flavor that the user enjoys from deteriorating even in the second half of the heating profile.

As shown in Table 1, the heating profile finally includes a heating end period. The heating end period is a period after the reheating period and is a period during which heating is not performed. The target temperature does not have to be set. As shown in FIG. 3, the temperature of the heating section 121 decreases after 260 seconds from the start of heating. Power supply to the heating unit 121 may be terminated 260 seconds after the start of heating. Even in that case, a sufficient amount of aerosol is generated for a while by the residual heat of the heating part 121 and the stick-shaped base material 150 . In the example shown in FIG. 3, the puffable period, ie, the heating session, ends 270 seconds after the start of heating.

The timing at which the puffable period starts and ends may be notified to the user. Furthermore, the user may be notified of the timing (for example, the timing when the power supply to the heating unit 121 ends) that is a predetermined time before the end of the puffable period. In that case, the user can perform puffing during the puffable period by referring to such notification.

(2) Acquisition of Suction Amount The sensor unit 112 is an example of a detection unit that detects information regarding suction of aerosol generated from the stick-shaped base material 150 heated by the heating unit 121 . Control unit 116 acquires the amount of suction based on the information detected by sensor unit 112 . The inhaled amount is the amount of aerosol inhaled by the user in one inhalation. The amount of aerosol inhaled by the user is believed to be correlated (eg, proportional) to the amount of air inhaled by the user. Therefore, the control unit 116 may calculate the amount of sucked air as the amount of sucked aerosol.

The sensor unit 112 may include a flow sensor that detects the flow rate of fluid. The flow rate sensor is provided, for example, in an air flow path that supplies air to the internal space 141 . The flow rate sensor detects the flow rate of air flowing through the air flow path as the user inhales. The control unit 116 determines the period during which an increase in the flow rate due to the user's inhalation is detected as the inhalation period. The inhalation period is a period of one breath from the start of inhalation of the aerosol by the user to the end of the inhalation. Then, the control unit 116 calculates the amount of suction by integrating the flow rate detected during the suction period. Alternatively, the control unit 116 may calculate the suction amount by multiplying the time length of the suction period and the flow rate per unit time.

The sensor unit 112 may include a pressure sensor. The pressure sensor is arranged, for example, in the airflow path, and detects pressure changes in the airflow path due to user's suction. The control unit 116 determines a period in which a pressure change accompanying the user's suction is detected as the suction period. Then, the control unit 116 estimates the amount of suction based on the integrated value of the pressure that has changed during the suction period. Alternatively, the control unit 116 may calculate the amount of suction by multiplying the length of time of the suction period by the amount of change in pressure per unit time.

The sensor unit 112 may include a sensor that detects the resistance value of the heating unit 121. The temperature of the heating unit 121 decreases as new air flows into the internal space 141 as the user inhales. The resistance value of the heating portion 121 changes as the temperature of the heating portion 121 changes. Therefore, the control unit 116 determines a period in which a change in the resistance value of the heating unit 121 due to suction by the user is detected as the suction period. Then, the control unit 116 estimates the amount of suction based on the integrated value of the resistance values that have changed during the suction period. Alternatively, the control unit 116 may calculate the amount of suction by multiplying the time length of the suction period by the amount of change in the resistance value per unit time.

The sensor unit 112 may include a sensor that detects the air pressure inside and outside the suction device 100 . An example of the air pressure inside the suction device 100 is the air pressure in the air flow path connected to the holding section 140 . Since the air pressure in the air flow path decreases as the user inhales, an air pressure difference occurs between the inside and outside of the suction device 100 . Therefore, the control unit 116 determines the period during which the pressure difference associated with the user's inhalation is detected as the inhalation period. Then, the control unit 116 estimates the suction amount based on the integrated value of the air pressure difference during the suction period. Alternatively, the control unit 116 may calculate the amount of suction by multiplying the length of time of the suction period and the average value of the pressure difference.

(3) Control of power supply amount according to suction amount Control unit 116 controls the amount of aerosol suctioned in the first suction period indicated by the information detected by sensor unit 112 in the first suction period to increase the second suction amount. The amount of power supplied to the heating unit 121 per unit time during the suction period is increased. An increase in the amount of power supplied per unit time is achieved, for example, by improving the duty ratio of the power pulse. As the amount of power supplied to the heating unit 121 per unit time increases, the amount of heat generated by the heating unit 121 increases. Therefore, it is possible to reduce the decrease in the suction amount of the aerosol and the flavor component due to the temperature decrease of the heating unit 121, thereby improving the quality of user experience.

The second suction period is a suction period later than the first suction period. As an example, the second suction period may be the next suction period after the first suction period. Aerosol inhalations are typically separated by seconds or more. In this regard, according to this configuration, a sufficient grace period for calculating the suction amount is provided between the first suction period for which the suction amount is calculated and the second suction period for which the power supply amount is controlled. can be ensured. Further, it takes time for the temperature of the heating unit 121 to reach the desired temperature after the amount of power supplied to the heating unit 121 is increased. In this regard, according to this configuration, it is possible to ensure a sufficient grace period for raising the temperature of the heating unit 121 to the desired temperature between the first suction period and the second suction period. .

The control unit 116 may increase the temperature of the heating unit 121 during the second suction period as the amount of aerosol sucked during the first suction period increases. In other words, the control unit 116 controls the amount of power supplied to the heating unit 121 per unit time so that the temperature of the heating unit 121 in the second suction period rises as the amount of aerosol sucked in the first suction period increases. may be increased. According to such a configuration, as the amount of aerosol sucked in the first sucking period increases, the temperature of the heating unit 121 rises in the second sucking period, and more aerosol and flavor component are delivered to the user. Become. In combustible tobacco, such as cigarettes, it is known that the higher the puff, the better the tobacco burns and the more flavor components are delivered to the user. In this regard, according to this configuration, it is possible to reproduce a user experience similar to that of a combustible cigarette.

In this specification, it is assumed that the temperature of the heating unit 121 increases as the amount of power supplied to the heating unit 121 per unit time increases, and the temperature decreases as the amount of power supply decreases. Also, when the amount of power supplied to the heating unit 121 per unit time is constant, the temperature of the heating unit 121 is maintained at a temperature corresponding to the amount of power supplied.

As described above, the control unit 116 performs temperature control based on the heating profile. Therefore, the control unit 116 performs temperature control in the second suction period based on the amount of aerosol sucked in the first suction period in addition to the heating profile. This point will be specifically described with reference to FIG.

FIG. 4 is a graph showing an example of transition of the temperature of the heating unit 121 when power supply control is performed based on the heating profile shown in Table 1 and the amount of aerosol sucked in the first sucking period. The horizontal axis of this graph is time (seconds). The vertical axis of this graph is the temperature of the heating unit 121 . A line 21 in this graph indicates transition of the temperature of the heating unit 121 . As shown in FIG. 4, the temperature of the heating unit 121 reaches 290° C. when 200 seconds have passed since the start of heating.

First, the control unit 116 predicts the start timing of the second suction period. At that time, the control unit 116 may predict the start timing of the second suction period based on the interval of the suction period detected in the past. For example, when the user sucked at an average interval of 30 seconds in the past heating session, and the previous suction was performed 180 seconds after the start of heating, the control unit 116 controls the It is predicted that the next suction period (corresponding to the second suction period) will start.

Then, the control unit 116 determines that the temperature of the heating unit 121 at the predicted start timing of the second suction period corresponds to the temperature of the heating unit 121 (that is, the target temperature) corresponding to the heating profile, and the aerosol in the first suction period. The temperature is controlled to be the sum of the temperature rise range that increases as the amount of suction of the air increases. In the example shown in FIG. 4, the start timing of the second suction period is predicted to be 210 seconds after the start of heating. It is also assumed that the temperature rise width corresponding to the amount of aerosol sucked in the first sucking period (for example, the last sucking period) is 15°C. Therefore, the control unit 116 controls the temperature of the heating unit 121 so that the temperature of the heating unit 121 reaches 305° C., which is the sum of the target temperature of 290° C. defined in the heating profile and the temperature increase width of 15° C., 210 seconds after the start of heating. , controls power supply to the heating unit 121 . Specifically, control unit 116 increases the amount of power supplied to heating unit 121 after 200 seconds from the start of heating. As a result, as shown in FIG. 4, the temperature of the heating unit 121 gradually increases from 200 seconds after the start of heating, and reaches 305° C. after 210 seconds from the start of heating.

After that, the control unit 116 maintains the temperature of the heating unit 121 at a temperature obtained by adding the temperature increase range to the target temperature from the predicted start timing of the second suction period to the actual end of the second suction period. control so that In the example shown in FIG. 4, puffs are detected from 212 seconds to 215 seconds after the start of heating. Therefore, control unit 116 controls power supply to heating unit 121 so that the temperature of heating unit 121 is maintained at 305° C. from 210 seconds to 215 seconds after the start of heating.

The notification unit 113 may notify the user of information indicating the timing at which the temperature of the heating unit 121 reaches the temperature obtained by adding the temperature increase range to the target temperature. In the example shown in FIG. 4, the notification unit 113 may emit light or vibrate 210 seconds after the start of heating. According to such a configuration, the user can perform suction at an appropriate timing by referring to the notification. Note that the timing at which the temperature of the heating unit 121 reaches the temperature obtained by adding the temperature increase range to the target temperature and the timing of the notification by the notification unit 113 may be mixed up.

A specific example of power supply control according to the present embodiment has been described above with reference to FIG. According to this control, the temperature of the heating unit 121 basically increases along the target temperature, and the temperature of the heating unit 121 temporarily increases during the suction period. According to such a configuration, it is possible to reproduce a user experience similar to that of a combustible cigarette while providing a suitable user experience based on the heating profile.

In order to realize the above temperature control, the control unit 116 sets the amount of power supply per unit time to the heating unit 121 during the second suction period to correspond to the first amount of power supply based on the heating profile and the range of temperature rise. is controlled so as to be the sum with the second power supply amount. The first power supply amount is the power supply amount for temperature control based on the heating profile. The second amount of power supply is the amount of power supply corresponding to the amount of aerosol sucked in the first sucking period. That is, the control unit 116 increases the amount of power supply according to the amount of suction at the timing when the suction is performed while controlling the power supply so that the temperature of the heating unit 121 changes along the target temperature. With such a configuration, the temperature control described with reference to FIG. 4 can be realized.

Next, the flow of processing related to power supply control described above will be described with reference to FIG. FIG. 5 is a flowchart showing an example of the flow of processing executed by the suction device 100 according to this embodiment.

As shown in FIG. 5, first, the control unit 116 determines whether or not a user operation requesting the start of heating has been detected (step S102). An example of a user operation requesting the start of heating is an operation on the suction device 100 such as operating a switch or the like provided on the suction device 100 . Another example of a user operation that requests initiation of heating is inserting a stick-shaped substrate 150 into the suction device 100 . The insertion of the stick-type substrate 150 into the suction device 100 is performed by a capacitance-type proximity sensor that detects the capacitance of the space near the opening 142, or a pressure sensor that detects the pressure in the internal space 141. , can be detected.

When it is determined that a user operation requesting the start of heating has not been detected (step S102: NO), the control unit 116 waits until a user operation requesting the start of heating is detected.

When it is determined that a user operation requesting the start of heating has been detected (step S102: YES), the control unit 116 controls the operation of the heating unit 121 to start heating based on the heating profile (step S104). For example, the control unit 116 starts power supply from the power supply unit 111 to the heating unit 121 based on the heating profile.

Next, the control unit 116 predicts the start timing of the next suction period (step S106). The start timing of the first suction period can be predicted, for example, based on the start timing of the first suction period in the previous heating session. The start timing of the second and subsequent suction periods can be predicted, for example, based on the end timing of the previous suction period and the interval between the suction periods in the previous heating session.

Next, the control unit 116 performs power supply control according to the amount of aerosol sucked based on the predicted start timing of the next sucking period (step S108). For example, the control unit 116 determines that the temperature of the heating unit 121 at the predicted start timing of the next suction period is the target temperature in the heating profile plus the temperature increase range corresponding to the amount of aerosol sucked in the previous suction period. The power supply to the heating unit 121 is controlled so as to reach

Next, the control unit 116 determines whether or not a condition for terminating power supply control according to the amount of aerosol sucked is satisfied (step S110). An example of a condition for ending power supply control according to the amount of aerosol sucked is that the user has finished sucking, that is, the end of the sucking period has been detected. Another example of the termination condition of the power supply control according to the aerosol suction amount is that a predetermined time has passed since the power supply control according to the aerosol suction amount was started.

If it is determined that the termination condition of the power supply control according to the aerosol suction amount is not satisfied (step S110: NO), the control unit 116 waits until the power supply control termination condition based on the aerosol suction amount is satisfied. stand by. As a result, from the predicted start timing of the second suction period to the actual end of the second suction period, the temperature of the heating unit 121 is equal to the target temperature defined in the heating profile plus the temperature rise range. will be maintained.

When it is determined that the termination condition for power supply control according to the aerosol suction amount is satisfied (step S110: YES), the control unit 116 ends power supply control according to the aerosol suction amount (step S112). That is, the control unit 116 returns to power supply control based on the heating profile. As a result, the temperature of the heating section 121 is lowered to the target temperature specified in the heating profile.

Next, the control unit 116 determines whether or not the termination condition is satisfied (step S114). An example of the end condition is that a predetermined time has passed since the start of heating. Another example of the termination condition is that the number of times of suction from the start of heating has reached a predetermined number.

If it is determined that the termination condition is not satisfied (step S114: NO), the process returns to step S106.

When it is determined that the termination condition is satisfied (step S114: YES), the control unit 116 terminates heating based on the heating profile (step S116). Specifically, control unit 116 terminates power supply from power supply unit 111 to heating unit 121 . After that, the process ends.

(4) First setting The correspondence relationship between the amount of aerosol sucked in the first sucking period and the amount of increase in the amount of power supply per unit time to the heating unit 121 in the second sucking period may be set variably. good. Such a setting is hereinafter also referred to as the first setting. The first setting will be described in detail below.

The control unit 116 may set a correspondence relationship between the amount of aerosol sucked in the first sucking period and the amount of increase in the amount of power supplied to the heating unit 121 per unit time in the second sucking period. In other words, the control unit 116 may set a correspondence relationship between the amount of aerosol sucked in the first sucking period and the temperature rise width of the heating unit 121 in the second sucking period. According to such a configuration, it is possible to further improve the quality of user experience by appropriately changing the correspondence relationship.

As an example, the control unit 116 may set the correspondence relationship according to the type of the stick-shaped base material 150 . This is because the appropriate correspondence relationship may vary depending on the type of stick-type base material 150 . With such a configuration, it is possible to set the above-described suitable correspondence relationship for each type of stick-shaped base material 150 .

As another example, the control unit 116 may set the correspondence according to the information received by the communication unit 115 . For example, the control unit 116 receives information indicating the correspondence to be set, and sets the correspondence indicated by the received information. The terminal device 200 is an example of the transmission source of the information indicating the correspondence relationship to be set. That is, the terminal device 200 may transmit information indicating the correspondence relationship to be set to the suction device 100 . Another example of a transmission source of information indicating the correspondence relationship to be set is a server. According to such a configuration, it is possible to set the above-mentioned suitable correspondence notified from another device.

Note that the communication unit 115 can receive an identifier indicating the correspondence to be set as information indicating the correspondence to be set. For example, an identifier of about several bits is assigned in advance to each of the plurality of candidates for the correspondence relationship that can be set, and the assigned identifier is transmitted and received. With such a configuration, it is possible to reduce the amount of communication.

As another example, the control unit 116 may set the correspondence relationship according to the user's operation detected by the sensor unit 112 . According to such a configuration, it is possible to set the correspondence relationship according to the user's preference.

(5) Second setting In the above example, control is performed to increase the power supply amount per unit time to the heating unit 121 in the second suction period as the amount of aerosol suction in the first suction period increases. , the execution/non-execution of such control may be set variably. Such settings are hereinafter also referred to as second settings. The second setting will be described in detail below.

The control unit 116 sets an operation mode selected from an operation mode group consisting of a plurality of operation modes including a first operation mode and a second operation mode. Then, the control unit 116 operates according to the set operation mode. When the first operation mode is set, control unit 116 performs the above control. That is, when the first operation mode is set, the control unit 116 determines the power supply amount per unit time to the heating unit 121 in the second suction period based on the heating profile and the amount of aerosol in the first suction period. Control based on suction volume. On the other hand, when the second operation mode is set, control unit 116 does not perform the above control. That is, when the second operation mode is set, the control unit 116 controls the power supply per unit time to the heating unit 121 during the second suction period regardless of the suction amount of the aerosol during the first suction period. control amount (e.g. control amount of power supply based on heating profile); According to such a configuration, it is possible to further improve the quality of user experience by appropriately changing the execution/non-execution of the control.

The control unit 116 may operate in an operation mode according to the information received by the communication unit 115. For example, when information indicating the operation mode to be set is received by the communication unit 115, the control unit 116 sets the operation mode indicated by the received information. The terminal device 200 is an example of a transmission source of information indicating the operation mode to be set. That is, the terminal device 200 may transmit information indicating the operation mode to be set to the suction device 100 . Another source of information indicating the operation mode to be set is the server. The information indicating the operation mode to be set is the execution or non-execution of control to increase the power supply amount per unit time to the heating unit 121 in the second suction period as the amount of aerosol suction in the first suction period increases. is an example of information for setting According to such a configuration, it is possible to set a suitable operation mode notified from another device.

The communication unit 115 can receive an identifier indicating the first operation mode or the second operation mode as information indicating the operation mode to be set. For example, an identifier of about several bits is assigned in advance to each of a plurality of operation modes included in the operation mode group, and the assigned identifier is transmitted and received. With such a configuration, it is possible to reduce the amount of communication.

Alternatively, the control unit 116 may set the operation mode according to the type of the stick-shaped base material 150. This is because the appropriate operation mode may differ depending on the type of stick-type base material 150 . Such a configuration makes it possible to deliver a suitable amount of aerosol and flavoring ingredients to the user.

Also, the control unit 116 may set the operation mode according to the user's operation detected by the sensor unit 112 . With such a configuration, it is possible to set an operation mode according to user's preference.

<4. Supplement>
Although the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention belongs can conceive of various modifications or modifications within the scope of the technical idea described in the claims. It is understood that these also belong to the technical scope of the present invention.

For example, in the above embodiment, the method of calculating the amount of aerosol inhaled by the user was exemplified, but the present invention is not limited to the example described above. The length of time of the inhalation period may be used as the aerosol inhalation amount. This is because the length of time of the suction period is considered to increase as the amount of suction increases. In this case, the control unit 116 increases the power supply amount per unit time to the heating unit 121 in the second suction period as the time length of the first suction period is longer. According to this configuration, the time length of the suction period, which is easier to obtain, can be substituted for the suction amount, so it is possible to reduce the processing load for calculating the suction amount.

For example, in the above embodiment, the first suction period is the suction period immediately before the second suction period, but the present invention is not limited to such an example. The first suction period may be two or more suction periods before the second suction period, or may be a suction period in a past heating session.

For example, in the above embodiment, an example in which the first suction period is one suction period has been described, but the present invention is not limited to such an example. The first suction period may include multiple suction periods. The amount of aerosol sucked in the first sucking period may be a statistic calculated from the sucked amount of aerosol in a plurality of sucking periods included in the first sucking period. An example of a statistic is an average or weighted average. For example, power supply control in the current heating session may be performed based on the average value of the amount of aerosol sucked in a plurality of sucking periods in the previous heating session. According to such a configuration, it is possible to reduce the influence of variations in the amount of aerosol sucked that occur in each sucking period on the quality of user experience.

For example, in the above embodiment, the heating profile is information that defines the time-series transition of the target value of the temperature of the heating unit 121, but the present invention is not limited to this example. The heating profile may be any information that defines the time-series transition of the target value of the parameter related to the temperature of the heating unit 121 . Then, the control unit 116 controls the operation of the heating unit 121 so that the measured value of the parameter related to the temperature of the heating unit 121 transitions in the same manner as the target value of the parameter related to the temperature of the heating unit 121 defined in the heating profile. do it. Parameters related to the temperature of the heating unit 121 include the resistance value of the heating unit 121 in addition to the temperature itself of the heating unit 121 described in the above embodiment.

For example, in the above-described embodiment, an example in which the temperature of the heating unit 121 is increased by increasing the amount of power supplied to the heating unit 121 per unit time during the second suction period has been described. is not limited to For example, if the amount of suction by the user is excessively large, the effect of increasing the temperature of the heating unit 121 due to the increase in the amount of power supplied to the heating unit 121 per unit time is canceled, and the temperature of the heating unit 121 may decrease. That is, the present invention is not necessarily limited to raising the temperature of the heating unit 121 during the second suction period.

A series of processes by each device described in this specification may be implemented using software, hardware, or a combination of software and hardware. A program that constitutes software is stored in advance in a recording medium (more specifically, a non-temporary computer-readable storage medium) provided inside or outside each device, for example. Each program, for example, is read into a RAM when executed by a computer that controls each device described in this specification, and is executed by a processor such as a CPU. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like. Also, the above computer program may be distributed, for example, via a network without using a recording medium.

Also, the processes described using the flowcharts and sequence diagrams in this specification do not necessarily have to be executed in the illustrated order. Some processing steps may be performed in parallel. Also, additional processing steps may be employed, and some processing steps may be omitted.
