- the control unit 116 performs suction heating when a generation request is made while preheating is being performed. Therefore, in the suction device 1, the control unit 116 controls power supply to the heating unit 121 as described above to shift to suction heating. In some cases, the process proceeds to suction heating without preheating.

- control unit 116 When it is determined that the suction heating end condition is not satisfied (NO in S205), the control unit 116 performs the processes after S204. If the suction heating end condition is satisfied (YES in S205), the control unit 116 stops power supply from the power supply unit 111 to the heating unit 121 to stop heating (S206).
- control unit 116 determines whether or not the preheating end condition is satisfied (S207).

- FIG. 3(a) is a timing chart for performing the first suction heating
- FIG. 3(b) is a timing chart for performing the second suction heating.
- FIG. 3A shows that at time t1, an operation for turning on the power of the suction device 1 (for example, an operation of quickly pressing the operation unit 117 three times in succession (an example of the first operation)) is performed, and then At time t2, a preliminary event is detected (for example, it is detected that the operation unit 117 has been pressed once (an example of a second operation)), and at time t3, a generation request is made (the operation unit 117 is held for a predetermined period (for example, two seconds). It shows the change in the temperature of the heating unit 121 when the continuous pressing is performed.
- FIG. 3(b) shows changes in the temperature of the heating unit 121 when an operation for turning on the power of the suction device 1 is performed at time t1, and a generation request is performed at time t3. .
- the first temperature reaches the first temperature earlier than in the second suction heating shown in FIG. 3(b). easy to reach. Therefore, in the case of the first suction heating, it is easier to reach the suckable period earlier than in the case of the second suction heating.
- the suction device 1 includes the heating unit 121 that heats the aerosol source that generates aerosol when heated, the power supply unit 111 that stores power, and the power supply unit 111 that supplies power to the heating unit 121. and a control unit 116 for controlling. Then, when an aerosol generation request is made, the control unit 116 performs suction heating as an example of the first heating so that the temperature of the aerosol source is equal to or higher than the first temperature at which the aerosol source is atomized.
- control unit 116 sets the temperature of the aerosol source to the second temperature or higher and the first Preheating is performed as an example of second heating to heat before suction heating so that the temperature is lower than the temperature.
- the suction device 1 configured in this way, by performing suction heating after preheating, a predetermined amount or more of aerosol is generated earlier than when suction heating is performed without preheating. reach a possible state.
- the second temperature has been exemplified as 40 degrees, it is not particularly limited to 40 degrees. Since the purpose of preheating is to raise the temperature of the aerosol source in advance before suction heating, the second temperature should be higher than the temperature of the location where the suction device 1 is used. For example, if the area where the suction device 1 is used is Japan, the second temperature should be higher than the air temperature in Japan. Since the temperature changes according to the season, the second temperature may be changed according to the season. Also, although the preheating target temperature is exemplified as 100 degrees, it is not particularly limited to 100 degrees. The preheating target temperature may be changed in the same manner as the second temperature, such as by setting the second temperature +60 degrees.
- the predetermined power value may be changed in the same manner as the change in the second temperature. good. That is, the predetermined electric power value and preheating target temperature may be changed according to the region and season in which the suction device 1 is used.
- preheating is performed when an event in which a generation request is expected to be made is detected before a generation request is made. Wasteful power consumption associated with preheating can be suppressed as compared with the case where preheating is started. That is, for example, even if the power of the suction device 1 is turned on, the user does not necessarily immediately issue a generation request. If the user does not issue a generation request after preheating is started when the power of the suction device 1 is turned on, the power required for preheating is wasted. On the other hand, according to the suction device 1, when an event in which a generation request is expected to be issued is detected after the power of the suction device 1 is turned on, for example, a predetermined operation is performed on the operation unit 117.
- Preheating is started when (for example, one press) is performed. Then, if an event expected to generate a generation request leads to a generation request by the user with a higher degree of certainty than other matters (for example, turning on the power of the suction device 1), preheating is performed. Since suction heating is performed with high accuracy after heating, the power required for preheating is less likely to be wasted.
- a modified example of detection of an event (preliminary event) in which a generation request is expected to be made will be described below.
- preheating by performing preheating before an aerosol generation request is made, it is possible to quickly create a state in which a predetermined amount or more of aerosol can be generated. Otherwise, power for preheating is wasted.
- preheating should be started before the minimum heating time at which the generation request is made after preheating. For example, power consumption for maintaining the preheating target temperature after reaching the preheating target temperature can be suppressed.
- the minimum heating time depends on the specifications of the heating unit 121 and the preheating target temperature, it can be exemplified to be 10 seconds or less.
- the minimum heating time is 5 seconds, if preheating is started 5 seconds before the production request is made, the preheating target temperature can be sufficiently reached when the production request is made. From the above, it is desirable to start preheating before the minimum heating time for which the generation request is made with high accuracy.
- the following events can be considered as preliminary events. That is, the suction device 1 has been moved to a position where the operation portion 117 can be visually recognized. This is because the user moves the suction device 1 to a position where the operation unit 117 can be operated before requesting aerosol generation (for example, pressing the operation unit 117 for a predetermined period of time (for example, two seconds) or longer).
- FIG. 4 is a diagram showing an example of schematic configurations of the sensor unit 112 and the control unit 116 according to the modification.
- the control unit 116 can exemplify detecting a preliminary event as follows. It is conceivable that the user picks up and lifts up the suction device 1 placed on a desk or table, for example, before making the generation request. Therefore, the sensor unit 112 has a gyro sensor 112j, and the control unit 116 detects a preliminary event when the output value of the gyro sensor 112j indicates that the orientation of the suction device 1 has been changed from horizontal to vertical. can be exemplified.
- the gyro sensor 112j can be exemplified as being provided inside the housing 10 .
- the suction device 1 is placed on a desk or table
- the power supply unit 111 and the heating unit 121 are oriented sideways so that the altitude is the same.
- the heating unit 121 is positioned above the power supply unit 110, in other words, the height of the heating unit 121 is higher than the height of the power supply unit 111. Become.
- the control unit 116 determines that the output value of the gyro sensor 112j is closer to the altitude of the heating unit 121 than the altitude of the power supply unit 111 from the value indicating that the altitude of the power supply unit 111 and that of the heating unit 121 are the same. Detecting a preliminary event can be exemplified when C changes to a value indicative of a large condition.
- the state in which the power supply unit 111 and the heating unit 121 have the same altitude is not limited to the case where the power supply unit 111 and the heating unit 121 have the same altitude. may be 1 cm or less. This is because when the height difference between the power supply unit 111 and the heating unit 121 is 1 cm or less, it can be considered that the suction device 1 is oriented sideways.
- the sensor unit 112 since the user touches the suction device 1 with a hand before making a generation request, the sensor unit 112 has a tactile sensor 112s, and the control unit 116 controls the output value of the tactile sensor 112s so that the hand touches the suction device 1. A preliminary event may be detected when it indicates that the is being touched.
- the tactile sensor 112s can be exemplified by being mounted on the housing 10 in a state of being exposed from the surface of the housing 10 that accommodates the power supply unit 110, for example.
- the suction device 1 may be moved from near the waist to a position where the operation unit 117 can be operated. Therefore, the sensor unit 112 may include the acceleration sensor 112a, and the control unit 116 may detect the preliminary event when the output value of the acceleration sensor 112a exceeds a predetermined threshold value.
- the suction device 1 is moved from bottom to top, a downward inertial force acts, and the acceleration sensor 112a indicates positive acceleration.
- An upward inertial force acts, and the acceleration sensor 112a indicates negative acceleration. Therefore, when the output value of the acceleration sensor 112a exceeds a predetermined threshold, it can be considered that the user has moved the suction device 1 from the vicinity of the waist to the mouth in order to perform a suction operation.
- the sensor unit 112 may include an altitude sensor 112h, and the control unit 116 may detect a preliminary event when the amount of change in the output value of the altitude sensor 112h exceeds a predetermined threshold.
- the control unit 116 uses the pressure sensor instead of using the output value of the altitude sensor 112h.
- a preliminary event may be detected by estimating that the suction device 1 has been moved from the vicinity of the waist to the mouth when the amount of change in the output value of the sensor is greater than or equal to a predetermined threshold value.
- the suction device 1 has at least two of the above-described gyro sensor 112j, tactile sensor 112s, acceleration sensor 112a, and altitude sensor 112h. Preliminary events may be detected based on For example, the controller 116 determines that the output value of the gyro sensor 112j indicates that the suction device 1 is oriented vertically, and that the output value of the acceleration sensor 112a indicates that the suction device 1 has moved from bottom to top. A preliminary event may be detected when This makes it possible to detect preliminary events with higher accuracy.
- the suction device 1 has at least three of the above-described gyro sensor 112j, tactile sensor 112s, acceleration sensor 112a, and altitude sensor 112h, and the control unit 116 controls output values from these three sensors. Preliminary events may be detected based on For example, the control unit 116 causes the output value of the gyro sensor 112j to indicate that the suction device 1 is oriented vertically, and the output value of the tactile sensor 112s to indicate that the hand is touching the suction device 1, In addition, the preliminary event may be detected when the output value of the acceleration sensor 112a indicates that the suction device 1 has moved from bottom to top.
- control unit 116 stops preheating when the preheating end condition is satisfied after performing preheating. For example, control unit 116 stops preheating when a predetermined time (for example, 60 seconds) has elapsed after starting preheating. Therefore, compared to a configuration in which preheating is continued until an aerosol generation request is made by the user after starting preheating, the preheating period can be shortened when the generation request is not made. Therefore, power consumption for preheating can be suppressed.
- a predetermined time for example, 60 seconds
- the preheating end condition may be the following condition other than the elapse of a predetermined time (for example, 60 seconds) after the preheating is started as described above.
- the control unit 116 sets the preheating end condition to that the output value of the gyro sensor 112j indicates that the orientation of the suction device 1 has been changed from vertical to horizontal.
- the control unit 116 determines that the altitude of the power supply unit 111 and that of the heating unit 121 are the same, based on the value indicating that the altitude of the heating unit 121 is higher than the altitude of the power supply unit 111, based on the output value of the gyro sensor 112j.
- a change to a value indicating a state is set as the preheating end condition. This is because, if the suction device 1 is placed, for example, on a desk or table, it is considered difficult for the user to issue a generation request.
- control unit 116 may set the fact that the output value of the tactile sensor 112s no longer indicates that the hand is touching the suction device 1 as the preheating end condition. This is because it is considered difficult for the user to make a generation request when the user releases the suction device 1 .
- control unit 116 determines that the output value of the acceleration sensor, which becomes a negative acceleration when the suction device 1 is moved from top to bottom, has become equal to or less than a predetermined negative threshold. It is good as This is because, for example, when the user moves the suction device 1 from a position where the operation unit 117 is visible to near the waist, the user is unlikely to make a generation request.
- the control unit 116 sets the amount of change in the output value of the altitude sensor 112h to a predetermined value.
- the preheating end condition may be set to be equal to or less than a negative threshold. This is because, for example, when the user moves the suction device 1 from the mouth to the vicinity of the waist, it is considered difficult for the user to make the generation request.
- the control unit 116 controls the suction device 1 to move from the mouth to the vicinity of the waist when the amount of change in the output value of the pressure sensor is equal to or less than a predetermined negative threshold value. It may be assumed that the preheating end condition is established by estimating that the preheating end condition is satisfied.
- the suction device 1 has at least two of the above-described gyro sensor 112j, tactile sensor 112s, acceleration sensor 112a, and altitude sensor 112h. may be used to determine whether or not the preheating end condition is satisfied.
- the controller 116 determines that the output value of the acceleration sensor 112a indicates that the suction device 1 has moved from top to bottom, and that the output value of the gyro sensor 112j indicates that the suction device 1 is oriented sideways. In this case, it may be determined that the preheating end condition is satisfied. This makes it possible to more accurately determine that the suction operation is not performed within the minimum heating time.
- control unit 116 can quickly determine with high accuracy that the user is unlikely to issue a generation request and stop preheating. It is possible to suppress wasteful power consumption associated with
- control unit 116 starts preheating when an event (preliminary event) in which a generation request is expected to be made is detected, but the present invention is not particularly limited to this aspect.
- Control unit 116 may initiate preheating without detecting a preliminary event.
- the control unit 116 may start preheating immediately after the suction device 1 is powered on and activated. That is, for example, when the operation unit 117 is quickly pressed three times in succession, the suction device 1 may be powered on, the control unit 116 may be activated, and the preheating may be started immediately.
- preheating it is possible to shorten the time from receiving a generation request to reaching a state where a predetermined amount or more of aerosol can be generated.
- By stopping preheating when the above-described preheating end condition is satisfied wasteful power consumption associated with preheating can be suppressed.
- the control unit 116 adjusts the power supplied to the heating unit 121 when performing the first suction heating (hereinafter sometimes referred to as “first suction heating power”) to the heating unit 121 when performing the second suction heating. may be smaller than the electric power (hereinafter sometimes referred to as "second suction heating power”) supplied to the first suction heating power ⁇ second suction heating power).

- FIG. 5(b) shows changes in electric power when the suction device 1 is turned on at time t1 and a generation request is made at time t3.
- the control unit 116 makes the duty ratio of the PWM signal output to the DC/DC converter 118 when performing the first suction heating smaller than the duty ratio when performing the second suction heating.
- the controller 116 can set the duty ratio when performing the first suction heating to 50% and the duty ratio when performing the second suction heating to 90%. Note that when performing the first suction heating, the control unit 116 fixes the duty ratio to 50% until the actual temperature reaches the first temperature, and after the actual temperature reaches the first temperature, the actual temperature and the target temperature, the duty ratio may be changed. Further, when performing the second suction heating, the control unit 116 fixes the duty ratio to 90% until the actual temperature reaches the first temperature, and after the actual temperature reaches the first temperature, the actual temperature and the target temperature, the duty ratio may be changed.
- the first suction heating power By making the first suction heating power smaller than the second suction heating power, when the first suction heating is performed, a portion other than the heating unit 121 (for example, the notification unit 113 or the communication unit 113) is used more than when performing the second suction heating.
- the power that can be supplied to the unit 115) can be increased. For example, during the preheating period, it is conceivable to give the highest priority to power supply to the heating portion 121 and lower the priority to power supply to other parts.
- the priority of power supply to the heating unit 121 is set to the highest and the duty ratio of the preheating period in the second suction heating is set to 90%, it is impossible to supply power to other parts during the preheating period. Have difficulty.

- the remaining 50% power supply to other parts Therefore, it becomes easier to supply power to other parts during the preheating period.
- the duty ratio when performing the first suction heating is set to 50%, and the duty ratio when performing the second suction heating is set to 90%. Although illustrated, it is not particularly limited to these duty ratios.
- the time from the start of suction heating until the first temperature is reached is the time when the second suction heating is started. It is desirable to set both duty ratios so as to be shorter than the time from when the temperature reaches the first temperature. As a result, it is possible to increase the power that can be supplied to parts other than the heating part 121 while shortening the time from receiving an aerosol generation request to reaching a state where a predetermined amount or more of aerosol can be generated.

図1は、第1実施形態に係る吸引装置1の概略構成の一例を模式的に示す図である。
第1実施形態に係る吸引装置1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1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1により生成される物質は、気体であってもよい。
吸引装置1は、電源ユニット110と、加熱部121と、保持部140とを有する。また、吸引装置1は、電源ユニット110、加熱部121等を収容するハウジング10を有する。吸引装置1においては、保持部140に、スティック型の部材であるスティック型基材150が保持された状態で、ユーザによる吸引が行われる。
DC/DCコンバータ118は、入力電圧を昇圧可能な昇圧回路であり、入力電圧を昇圧した電圧又は入力電圧を加熱部121に供給可能に構成されている。DC/DCコンバータ118によれば加熱部121に供給される電力を調整できる。DC/DCコンバータ118としては、例えば、出力電圧を監視しながらスイッチング素子のオン/オフ時間を制御することで、入力電圧を希望する出力電圧に変換するスイッチングレギュレータを用いることができる。DC/DCコンバータ118としてスイッチングレギュレータを用いる場合には、スイッチング素子を制御することで、入力電圧を昇圧せずに、そのまま出力させることもできる。
また、温度センサ112tは、加熱部121の近傍に配置される、例えばサーミスタであっても良い。
基材部151は、エアロゾル源を含む。エアロゾル源は、加熱されることで霧化され、エアロゾルが生成される。エアロゾル源は、例えば、刻みたばこ又はたばこ原料を、粒状、シート状、又は粉末状に成形した加工物などの、たばこ由来のものであってもよい。また、エアロゾル源は、たばこ以外の植物(例えばミント及びハーブ等)から作られた、非たばこ由来のものを含んでいてもよい。一例として、エアロゾル源は、メントール等の香料成分を含んでいてもよい。吸引装置1が医療用吸入器である場合、エアロゾル源は、患者が吸入するための薬剤を含んでもよい。なお、エアロゾル源は固体に限られるものではなく、例えば、グリセリン及びプロピレングリコール等の多価アルコール、並びに水等の液体であってもよい。基材部151の少なくとも一部は、スティック型基材150が保持部140に保持された状態において、保持部140の内部空間141に収容される。
制御部116は、吸引装置1の電源がONにされると起動する。例えば、操作部117が連続で素早く3回押された場合に、吸引装置1の電源がONとなり、制御部116が起動する。そして、制御部116は、エアロゾル生成の要求(以下、「生成要求」と称する場合がある。)があった場合に、基材部151に含まれるエアロゾル源の温度を、当該エアロゾル源が霧化する第1温度以上にするべく加熱部121への給電を行う。生成要求は、操作部117が所定期間(例えば2秒)以上継続して押されることであることを例示することができる。なお、生成要求を行う対象は、吸引装置1の電源をONにするために所定の起動操作を行う対象である操作部117とは異なる操作部であっても良い。第1温度は、230度であることを例示することができる。なお、吸引装置1は、吸引装置1とは別体に設けられた装置(例えば吸引装置1に充電を行う装置)との接続が解除されたときに電源がONとなっても良い。
それゆえ、吸引装置1においては、上述したように制御部116が加熱部121への給電を制御することで吸引加熱に移行する過程として、予備加熱を行った後に吸引加熱に移行する場合と、予備加熱を行うことなく吸引加熱に移行する場合とがある。以下の説明において、予備加熱を行った後に吸引加熱に移行した場合の吸引加熱を、「第1吸引加熱」、予備加熱を行うことなく吸引加熱に移行した場合の吸引加熱を、「第2吸引加熱」と称する場合がある。
制御部116は、この処理を、例えば予め定めた制御周期にて(例えば1ミリ秒毎に)繰り返し実行する。
制御部116は、予備事象を検知したか否かを判定する(S201)。予備事象を検知した場合(S201でYES)、制御部116は、予備加熱を行う(S202)。その後、制御部116は、生成要求が行われたか否かを判定する(S203)。生成要求が行われた場合(S203でYES)、制御部116は、第1吸引加熱を行う(S204)。その後、吸引加熱終了条件が成立したか否かを判定する(S205)。吸引加熱終了条件が成立していないと判定した場合(S205でNO)、制御部116は、S204以降の処理を行う。吸引加熱終了条件が成立した場合(S205でYES)、制御部116は、電源部111から加熱部121への給電を停止させて加熱を停止させる(S206)。
図3(a)は、時刻t1において吸引装置1の電源をONにするための操作(例えば操作部117が連続で素早く3回押される操作(第1操作の一例))が行われ、その後の時刻t2において予備事象を検知(例えば操作部117が1回押されたこと(第2操作の一例)を検知)し、その後の時刻t3において生成要求(操作部117が所定期間(例えば2秒)以上継続して押されること)が行われた場合の加熱部121の温度の変化を示している。
図3(b)は、時刻t1において吸引装置1の電源をONにするための操作が行われ、その後の時刻t3において生成要求が行われた場合の加熱部121の温度の変化を示している。
以下に、生成要求が行われると予想される事象(予備事象)の検知の変形例について説明する。
ここで、エアロゾルの生成要求が行われる前に予備加熱を行うことで、早期に既定量以上のエアロゾルを生成可能な状態とすることができるが、予備加熱を行った後に、生成要求が行われなければ予備加熱のための電力が無駄となってしまう。また、予備加熱を開始した後、予備加熱目標温度に達するまでの時間を、「最小加熱時間」と称すると、予備加熱を行った後に生成要求が行われる最小加熱時間前に予備加熱を開始すれば、予備加熱目標温度に達した後に予備加熱目標温度に維持するための電力消費を抑制することができる。最小加熱時間は、加熱部121の仕様や予備加熱目標温度にも依るが、10秒以下であることを例示することができる。最小加熱時間が5秒である場合、生成要求の5秒前に予備加熱を開始すれば、生成要求が行われるときには十分に予備加熱目標温度にすることができる。
以上のことより、生成要求が確度高く行われる最小加熱時間前に予備加熱を開始することが望ましい。
以上の事項に鑑み、制御部116は、以下のようにして予備事象を検知することを例示することができる。
ユーザが生成要求を行う前に、例えば机やテーブルの上に置いてある吸引装置1を手に取って持ち上げることが考えられる。そこで、センサ部112がジャイロセンサ112jを有し、制御部116は、ジャイロセンサ112jの出力値が吸引装置1の向きが横から縦に変えられたことを示した場合に、予備事象を検知することを例示することができる。ジャイロセンサ112jは、ハウジング10内に設けられていることを例示することができる。なお、吸引装置1は、机やテーブルの上に置かれている場合には、電源部111と加熱部121との高度が同じである状態の横向きとなる。他方、ユーザが生成要求を行うときには、加熱部121が電源ユニット110よりも上方に位置する状態、言い換えれば、電源部111の高度よりも加熱部121の高度の方が大きい状態である縦向きとなる。それゆえ、制御部116は、ジャイロセンサ112jの出力値が、電源部111と加熱部121との高度が同じである状態を示す値から、電源部111の高度よりも加熱部121の高度の方が大きい状態を示す値に変わった場合に、予備事象を検知することを例示することができる。なお、電源部111と加熱部121との高度が同じである状態とは、電源部111と加熱部121との高度が全く同じである場合に限定されず、例えば電源部111と加熱部121との高度差が1cm以下である場合であっても良い。電源部111と加熱部121との高度差が1cm以下である場合には、吸引装置1が横向きであるとみなすことができるからである。
以上説明したように、吸引装置1においては、制御部116は、予備加熱を行った後、予備加熱終了条件が成立した場合に、予備加熱を停止する。例えば、制御部116は、予備加熱を開始した後、予め定められた時間(例えば60秒)が経過した場合に予備加熱を停止する。それゆえ、予備加熱を開始した後にユーザによりエアロゾルの生成要求が行われるまで予備加熱を継続する構成と比較すると、生成要求が行われなかった場合に、予備加熱を行う期間を短くすることができるので、予備加熱のための電力消費を抑制することができる。
制御部116は、ジャイロセンサ112jの出力値が吸引装置1の向きが縦から横に変えられたことを示したことを、予備加熱終了条件とすることを例示することができる。言い換えれば、制御部116は、ジャイロセンサ112jの出力値が、電源部111の高度よりも加熱部121の高度の方が大きい状態を示す値から、電源部111と加熱部121との高度が同じである状態を示す値に変わったことを、予備加熱終了条件とすることを例示することができる。吸引装置1が、例えば机やテーブルに置かれた場合には、ユーザにより生成要求が行われ難いと考えられるからである。
制御部116は、第1吸引加熱を行う際に加熱部121に供給する電力(以下、「第1吸引加熱電力」と称する場合がある。)を、第2吸引加熱を行う際に加熱部121に供給する電力(以下、「第2吸引加熱電力」と称する場合がある。)よりも小さくしても良い(第1吸引加熱電力<第2吸引加熱電力)。
図6は、第2実施形態に係る吸引装置2の概略構成の一例を模式的に示す図である。
第2実施形態に係る吸引装置2は、第1実施形態に係る吸引装置1に対して、加熱部121に代えて加熱部221を備えるとともに断熱部244を備える点が異なる。以下、第1実施形態と異なる点について説明する。第1実施形態と第2実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
図7は、第3実施形態に係る吸引装置3の概略構成の一例を模式的に示す図である。
第3実施形態に係る吸引装置3は、第1実施形態に係る吸引装置1に対して、加熱部121に加えて加熱部221を備えるとともに、断熱部244を備える点が異なる。以下、第1実施形態と異なる点について説明する。第1実施形態と第3実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
また、図7では、加熱部221が、保持部140の外周に配置される例を示したが、本構成例はかかる例に限定されない。例えば、加熱部221は、保持部140の底部143を覆うように配置されても良い。
図8は、第4実施形態に係る吸引装置4の概略構成の一例を模式的に示す図である。
第4実施形態に係る吸引装置4は、第1実施形態に係る吸引装置1に対して、加熱部121、保持部140に代えて、加熱部421、保持部440を備えるとともに、断熱部444を備える点が異なる。以下、第1実施形態と異なる点について説明する。第1実施形態と第4実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
図9は、第5実施形態に係る吸引装置5の概略構成の一例を模式的に示す図である。
第5実施形態に係る吸引装置5は、第1実施形態に係る吸引装置1に対して、エアロゾル源を含む基材を、誘導加熱(IH(Induction Heating))により加熱することで、エアロゾルを生成する点が異なる。以下、第1実施形態と異なる点について説明する。第1実施形態と第5実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
サセプタ561は、スティック型基材150に含まれる。サセプタ561は、電磁誘導により発熱する。サセプタ561は、金属等の導電性の素材により構成される。一例として、サセプタ561は、金属片である。サセプタ561は、エアロゾル源に近接して配置される。図9に示した例では、サセプタ561は、スティック型基材150の基材部151に含まれる。
図10は、第6実施形態に係る吸引装置6の概略構成の一例を模式的に示す図である。
第6実施形態に係る吸引装置6は、第2実施形態に係る吸引装置2に対して、エアロゾル源を含む基材を加熱することでエアロゾルを生成するのに加えて、液体としてのエアロゾル源を加熱することでエアロゾルを生成する点が異なる。以下、第1実施形態と異なる点について説明する。第1実施形態と第6実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
また、上述した吸引可能期間が開始したときに、液体の温度を、第2温度以上であり、かつ、液体の沸点よりも低い温度(例えば50度)とするべく加熱部621を加熱開始するとともに、その後、ユーザによる吸引が行われたことがセンサ部112に設けられた圧力センサにより検出された場合に、液体の温度を沸点以上とするべく加熱部621を加熱し、エアロゾルを生成するようにしても良い。これにより、吸引初期から高霧化量を吸引可能とすることができる。
振動によりエアロゾルの生成が行われる場合、吸引装置6は、加熱部621に代えて、振動部を備える。例えば、振動部は、超音波振動子として機能する圧電セラミックスを含む板状の部材により構成される。そして、振動部が振動すると、液誘導部622により振動部の表面に誘導されたエアロゾル源が、振動部による振動に伴い発生した超音波により霧化され、エアロゾルが生成される。
