- the control unit 116 controls the temperature of the heating unit 121 so that the transition of the temperature of the heating unit 121 (hereinafter also referred to as the actual temperature) is the same as the transition of 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 power supply to the heating unit 121 based on the heating profile, it is possible to optimize the flavor tasted by the user.

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, stops heating by the heating unit 121 when the actual temperature reaches the target temperature, and stops the heating by the heating unit 121. When the temperature becomes low, heating by the heating unit 121 may be performed again.
- PWM pulse width modulation
- PFM pulse frequency modulation
- 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.

- 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.
- FIG. 2 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.
- the horizontal axis of this graph is time (seconds).

- a line 21 in this graph indicates transition of the temperature of the heating unit 121 .
- the temperature of the heating unit 121 transitions in the same manner as the target temperature defined in the heating profile.
- 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 to a predetermined temperature.
- the initial temperature is the temperature of the heating unit 121 at the start of heating.
- 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.
- the temperature of the stick-type substrate 150 reaches a temperature at which a sufficient amount of aerosol is generated.
- 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.
- 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 .
- the heating part 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.
- the 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.
- the heating profile includes a reheating period after an intermediate temperature decreasing period.
- the reheating period is a period after the temperature of the heating unit 121 has decreased, and is a period during which the temperature of the heating unit 121 increases.
- the temperature of the heating unit 121 increases 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.
- 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.
- 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.
- 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.
- 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 .
- the puffable period ie the heating session, ends.
- 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.

- the control unit 116 turns on the switching element 118 for a period corresponding to the ON pulse width in PWM control, and turns off the switching element 118 for a period corresponding to the OFF pulse width.
- a power pulse having a voltage adjusted by the DC/DC converter 117 and having a pulse width adjusted by the switching element 118 is applied to the heating unit 121 .
- the PID control gain refers to the gain Kp of the proportional term, the gain Ki of the integral term, and the gain Kd of the differential term. If noise is added to the PID control gain, it becomes difficult to appropriately control the temperature of the heating unit 121, and inappropriate aerosol may be delivered to the user.

- a second voltage different from the voltage is controlled to be applied to the heating unit 121 . That is, the control unit 116 adjusts the voltage applied to the heating unit 121 at specific timings in the heating profile. Therefore, the timing at which noise is added to the PID control gain is determined by the relationship with the heating profile. Therefore, it is possible to appropriately control the temperature of the heating unit 121 as compared with the case where the voltage is adjusted irregularly and frequently, that is, the gain of the PID control is irregularly and frequently affected by noise.

Therefore, it is possible to appropriately control the temperature of the heating unit 121 in the first period and the second period, and deliver an appropriate aerosol to the user.
- the third period may be a reheating period. That is, the control unit 116 applies the first voltage to the heating unit 121 during the initial heating period, sets the voltage applied to the heating unit 121 to 0 during the reheating period, and applies the second voltage during the reheating period. may be applied to the heating unit 121 . According to such a configuration, it is possible to appropriately control the temperature of the heating unit 121 and deliver an appropriate aerosol to the user throughout the heating session.

- control unit 116 determines whether or not the termination condition is satisfied (step S110).
- An example of the termination condition is that the elapsed time from the start of heating has reached a predetermined time.
- Another example of the termination condition is that the number of puffs from the start of heating has reached a predetermined number.
- step S110 NO
- the control unit 116 waits until the termination condition is satisfied.
- step S110 YES
- the control unit 116 terminates heating based on the heating profile (step S112). After that, the process ends.

- the ambient temperature is the ambient temperature that can affect the temperature of the heating unit 121 .
- the environmental temperature includes the temperature around the suction device 100 (that is, the air temperature), the temperature inside the housing of the suction device 100, the temperature of the power supply unit 111, and the like.
- the suction device 100 may have a temperature sensor for detecting the environmental temperature, or may receive the environmental temperature from a smartphone, server, or the like. Considering that the ambient temperature can affect the temperature of the heating unit 121, such a configuration enables the temperature control of the heating unit 121 to be performed more appropriately.
- the control unit 116 sets default values for the first voltage and the second voltage when the environmental temperature is equal to or higher than the first reference value and lower than the second reference value. According to the example shown in Table 2, when the ambient temperature is 10° C. or more and less than 30° C., the control unit 116 sets the first voltage to the default V1 and the second voltage to the default V2. .
- the control unit 116 sets the first voltage and the second voltage to higher values when the ambient temperature is less than the first reference value.
- the control unit 116 sets the first voltage to V1B , which is higher than the default V1 , and sets the second voltage to the default V2.
- V 2B be higher than The lower the ambient temperature, the greater the power required to maintain and raise the temperature of the heating unit 121 . In this respect, according to this configuration, it is possible to easily maintain and raise the temperature of the heating unit 121 by increasing the applied voltage.
- the control unit 116 sets the first voltage and the second voltage to lower values when the environmental temperature is equal to or higher than the second reference value.
- the second reference value is greater than or equal to the first reference value.
- the control unit 116 sets the first voltage to V1A , which is lower than the default V1 , and sets the second voltage to the default V2.
- V 2A lower than The higher the ambient temperature, the smaller the power required to maintain and raise the temperature of the heating unit 121 .
- by lowering the applied voltage it is possible to suppress power consumption while maintaining and increasing the temperature of the heating unit 121 .
- the control unit 116 may determine the first voltage and the second voltage based on the environmental temperature before controlling the operation of the heating unit 121 based on the heating profile.
- the environmental temperature can change according to the temperature change of the heating unit 121 , such as the temperature of the space around the suction device 100 locally rising as the temperature of the heating unit 121 rises. In this respect, according to this configuration, it is possible to determine the first voltage and the second voltage while eliminating the influence of the temperature change of the heating unit 121 .
- the present invention is not limited to such an example. At least one of the first voltage and the second voltage may be controlled based on the environmental temperature.
- the control unit 116 may control the second voltage based on the temperature of the heating unit 121 during the initial temperature rising period.
- the ambient temperature can affect the temperature of the heating section 121 . Therefore, it is considered that the temperature of the heating unit 121 in the first period is affected by the environmental temperature.
- control unit 116 sets the second voltage to a higher value when the temperature increase rate of the heating unit 121 during the first period is less than the third reference value. It is assumed that the environmental temperature is low due to the slow temperature rise rate of the heating unit 121 in the first period. In this respect, according to this configuration, it is possible to easily maintain and raise the temperature of the heating unit 121 by increasing the applied voltage.
- control unit 116 sets the second voltage to a lower value when the temperature increase rate of the heating unit 121 in the first period is equal to or higher than the fourth reference value.
- a fourth reference value is a value equal to or greater than the third reference value. It is assumed that the environmental temperature is high due to the high rate of temperature increase of the heating unit 121 in the first period. In this respect, according to such a configuration, by lowering the applied voltage, it is possible to suppress power consumption while maintaining and increasing the temperature of the heating unit 121 .
- the control unit 116 may control the second voltage based on information on the aerosol puff performed by the user during the initial temperature rising period.
- An example of information about puffs here is the number of puffs.
- control unit 116 sets the second voltage to a higher value when the number of puffs performed in the first period is equal to or greater than the fifth reference value. As the number of puffs increases, the temperature of the heating unit 121 tends to decrease, so it is assumed that the power required to maintain and raise the temperature of the heating unit 121 is large. In this respect, according to this configuration, it is possible to easily maintain and raise the temperature of the heating unit 121 by increasing the applied voltage.
- control unit 116 sets the second voltage to a lower value when the number of puffs performed in the first period is less than the sixth reference value.
- the sixth reference value is a value equal to or less than the fifth reference value. Since the temperature of the heating unit 121 is less likely to drop as the number of puffs is reduced, it is assumed that the power required to maintain and raise the temperature of the heating unit 121 is small. In this respect, according to such a configuration, by lowering the applied voltage, it is possible to suppress power consumption while maintaining and increasing the temperature of the heating unit 121 .
- the control unit 116 controls at least one of the first voltage and the second voltage based on the type of the stick-shaped substrate 150 heated by the heating unit 121. good too.
- the types and contents of the aerosol source and the flavor source differ for each type of stick-type base material 150, and it is considered that the easiness of temperature rise also differs accordingly.
- the suction device 100 may include multiple heating units 121 .
- the control unit 116 controls the voltage applied to each of the plurality of heating units 121 at timing according to the heating profile.
- a plurality of heating units 121 heat different portions of the stick-shaped substrate 150 .
- each portion of the stick-shaped substrate 150 can be temperature-controlled with an appropriate voltage. This makes it possible to reduce power consumption while delivering a more appropriate flavor to the user.

- FIG. 5 The voltage control when the suction device 100 has two heating units 121 will be described with reference to FIGS. 5 and 6.
- FIG. 5 is a schematic diagram schematically showing a configuration example of the suction device 100 according to this modified example.
- the suction device 100 according to this modification differs from the example shown in FIG. 1 in that it has two heating units 121 (heating units 121A and 121B).
- heating units 121A and 121B heating units 121A and 121B.
- the heating part 121A and the heating part 121B are arranged at different positions in the direction in which the stick-shaped base material 150 is inserted. Specifically, the heating section 121A is arranged on the downstream side, which is the side closer to the opening 142 . On the other hand, the heating section 121B is arranged on the upstream side, which is the side closer to the bottom section 143 . When the puff is performed, an air flow is generated from upstream to downstream.
- the control unit 116 raises the temperature of the heating unit 121A first, and then raises the temperature of the heating unit 121B.
- the control unit 116 may start heating in order from the heating unit 121A to the heating unit 121B, or may raise the temperature to the maximum temperature in order.
- the aerosol sources are heated in order from the downstream side to the upstream side of the base material portion 151 to generate the aerosol. If the upstream portion of the substrate portion 151 is heated earlier than the downstream portion, the aerosol generated on the upstream side may be cooled and condensed when passing through the downstream portion. be.
- the downstream portion of the base material portion 151 that has not yet been heated becomes wet, and the flavor that the user enjoys when the downstream portion of the base portion 151 is heated may deteriorate.
- the generated aerosol does not pass through the unheated portion of the base material portion 151 . Therefore, it is possible to prevent the unheated portion of the base material portion 151 from getting wet, thereby preventing deterioration of the flavor tasted by the user.

- a line 31B in this graph indicates transition of the temperature of the heating unit 121B.
- the temperature of the heating portion 121A is rapidly increased to reach 310.degree. C., and then maintained at 310.degree.
- the heating unit 121A lowers the temperature to 100° C. in the third period and maintains the temperature at 100° C. in the subsequent second period.
- the temperature of the heating portion 121B is slowly increased to 310°C in the fourth period after the first period, and reaches 310°C at the timing when the temperature of the heating portion 121A is decreased to 100°C. After that, when the second period and the fourth period are completed, the temperature of the heating section 121A and the heating section 121B is lowered.
- the control unit 116 controls so that the first voltage V1 is applied to the heating unit 121A during the first period, and the second voltage V2 is applied to the heating unit 121A during the second period. According to such a configuration, it is possible to raise the temperature of the heating portion 121A at once during the first period and finish preheating early. Then, the temperature of the heating part 121A is maintained in the second period to prevent the aerosol generated in the upstream part of the base material part 151 from being cooled and condensed when passing through the downstream part. It becomes possible to
- the control unit 116 controls so that no voltage is applied to the heating unit 121A during the third period sandwiched between the first period and the second period.
- the first voltage V1 is higher than the second voltage V2 . According to such a configuration, it is possible to shorten the preheating period while preventing exhaustion of the aerosol source and suppressing power consumption during the second period.
- control unit 116 controls so that the fourth voltage is applied to the heating unit 121B in the fourth period overlapping the first period and the second period. More simply, the control unit 116 controls so that the fourth voltage is constantly applied to the heating unit 121B. With such a configuration, it is possible to prevent noise from being added to the gain of PID control. Therefore, it is possible to appropriately control the temperature of the heating unit 121B throughout the fourth period and deliver an appropriate aerosol to the user.
- the fourth voltage is lower than the first voltage and higher than the second voltage. As shown in FIG. 6, the temperature of the heating portion 121A reaches 310° C. before the temperature of the heating portion 121B reaches 310° C., and sufficient aerosol is generated on the downstream side. no need to let In this respect, according to this configuration, it is possible to sufficiently raise the temperature of the heating unit 121B while suppressing power consumption.

Abstract
Description
吸引装置は、ユーザにより吸引される物質を生成する装置である。以下では、吸引装置により生成される物質が、エアロゾルであるものとして説明する。他に、吸引装置により生成される物質は、気体であってもよい。
(1)加熱プロファイル
制御部116は、温度設定に基づいて、加熱部121の動作を制御する。加熱部121の動作の制御は、電源部111から加熱部121への給電を制御することにより、実現される。温度設定とは、加熱部121の温度の目標値である目標温度の時系列推移を規定する情報である。以下では、かかる温度設定を、加熱プロファイルとも称する。
制御部116は、加熱部121に印可される電圧を制御する。加熱部121に印可される電圧の制御について、図3を参照しながら詳しく説明する。
(1)第1の変形例
制御部116は、環境温度に基づいて、第1の電圧及び第2の電圧を制御してもよい。環境温度とは、加熱部121の温度に影響を与え得る環境の温度である。例えば、環境温度としては、吸引装置100の周囲の温度(即ち、気温)、吸引装置100の筐体内の温度、電源部111の温度等が挙げられる。吸引装置100は、環境温度を検出するための温度センサを有していてもよいし、スマートフォン又はサーバ等から環境温度を受信してもよい。環境温度が加熱部121の温度に影響を与え得ることを考慮すれば、かかる構成により、加熱部121の温度制御をより適切に行うことが可能となる。
制御部116は、初期昇温期間における加熱部121の温度に基づいて、第2の電圧を制御してもよい。第1の変形例において上記説明したように、環境温度は加熱部121の温度に影響を与え得る。そのため、第1の期間における加熱部121の温度は、環境温度による影響を受けていると考えられる。この点、かかる構成によれば、初期昇温期間において判明した環境温度による影響を考慮して、再昇温期間における加熱部121の温度制御をより適切に行うことが可能となる。
制御部116は、初期昇温期間においてユーザにより行われたエアロゾルのパフに関する情報に基づいて、第2の電圧を制御してもよい。ここでのパフに関する情報の一例は、パフ回数である。パフが行われると、外気が内部空間141に流入し、加熱部121の温度が低下する。この点、かかる構成によれば、初期昇温期間において判明したパフによる影響を考慮して、再昇温期間における加熱部121の温度制御をより適切に行うことが可能となる。
制御部116は、加熱部121により加熱されるスティック型基材150の種類に基づいて、第1の電圧又は第2の電圧の少なくともいずれか1つを制御してもよい。スティック型基材150の種類ごとに、エアロゾル源及び香味源の種類及び含有量は異なり、それに伴い昇温のしやすさも異なると考えられる。この点、かかる構成によれば、スティック型基材150の種類ごとの昇温しやすさを考慮して、加熱部121の温度制御をより適切に行うことが可能となる。
上記実施形態では、吸引装置100が1つの加熱部121を備える例を説明したが、本発明はかかる例に限定されない。吸引装置100は、複数の加熱部121を備えていてもよい。その場合、制御部116は、複数の加熱部121の各々に印可される電圧を、加熱プロファイルに応じたタイミングで制御する。複数の加熱部121は、スティック型基材150の異なる部分を加熱する。この点、かかる構成によれば、スティック型基材150の各部分を適切な電圧で温度制御することができる。これにより、より適切な香味をユーザに送達しつつ、消費電力を抑制することが可能となる。
以上、添付図面を参照しながら本発明の好適な実施形態について詳細に説明したが、本発明はかかる例に限定されない。本発明の属する技術の分野における通常の知識を有する者であれば、請求の範囲に記載された技術的思想の範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、これらについても、当然に本発明の技術的範囲に属するものと了解される。
