DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In addition, in this specification and drawings, components having substantially the same functional configuration are assigned the same reference numerals, thereby omitting redundant description.

<1. Configuration example>

Fig. 1 is a schematic diagram schematically showing a configuration example of a suction device 100 according to one embodiment. 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, and a control unit 116. ), an electromagnetic induction source 162, and a receiving portion 140. With the stick-shaped substrate 150 accommodated in the receiving portion 140, suction is performed by the user. Hereinafter, each component will be described in order.

The power supply unit 111 accumulates power. And, the power supply unit 111 supplies power to each component of the suction device 100. The power supply unit 111 may be configured by, for example, a rechargeable battery such as a lithium ion secondary battery. The power supply unit 111 may be charged by being connected to an external power source using a USB (Universal Serial Bus) cable or the like. Additionally, the power supply unit 111 may be charged while not connected to a device on the power transmission side using wireless power transfer technology. In addition, only the power source unit 111 may be separated from the suction device 100 or may be replaced with a new power source unit 111.

The sensor unit 112 detects various information regarding the suction device 100. Then, the sensor unit 112 outputs the detected information to the control unit 116. As an example, the sensor unit 112 is comprised of a pressure sensor such as a condenser microphone, a flow rate sensor, or a temperature sensor. Then, when the sensor unit 112 detects the numerical value accompanying suction by the user, it outputs information indicating that suction by the user has been performed to the control unit 116. As another example, the sensor unit 112 is comprised of an input device that accepts input of information from the user, such as a button or switch. In particular, the sensor unit 112 may include a button instructing to start/stop aerosol generation. Then, the sensor unit 112 outputs information input by the user to the control unit 116. As another example, the sensor unit 112 is comprised of a temperature sensor that detects the temperature of the susceptor 161. Such a temperature sensor detects the temperature of the susceptor 161 based on the electrical resistance value of the electromagnetic induction source 162, for example.

The notification unit 113 notifies information to the user. As an example, the notification unit 113 is comprised of a light emitting device such as an LED (Light Emitting Diode). In this case, the notification unit 113 provides different notifications when the state of the power source unit 111 is required charging, when the power source unit 111 is charging, and when an abnormality occurs in the suction device 100. It emits light in a luminous pattern. The light emission pattern here is a concept that includes color and timing of turning on/off, etc. The notification unit 113 may be comprised of a display device that displays an image, a sound output device that outputs sound, a vibration device that vibrates, etc. together with or instead of a light emitting device. Additionally, the notification unit 113 may notify information indicating that attraction by the user has become possible. Information indicating that suction by the user has become possible can be notified when the temperature of the stick-shaped base material 150 generated by electromagnetic induction reaches a predetermined temperature.

The storage unit 114 stores various information for the operation of the suction device 100. The storage unit 114 is comprised of a non-volatile storage medium such as flash memory, for example. An example of information stored in the storage unit 114 is information about the OS (Operating System) of the suction device 100, such as the control contents of various components by the control unit 116. Another example of information stored in the storage unit 114 is information about suction by the user, such as the number of suctions, the suction time, and the cumulative suction time.

The communication unit 115 is a communication interface for transmitting and receiving information between the suction device 100 and other devices. The communication unit 115 performs communication based on any wired or wireless communication standard. Such communication standards include, for example, wireless LAN (Local Area Network), wired LAN, Wi-Fi (registered trademark), Bluetooth (registered trademark), NFC (Near Field Communication), or LPWA (Low Power Wide Area). etc. may be employed. As an example, the communication unit 115 transmits information about attraction by the user to the server. As another example, the communication unit 115 receives new OS information from the server in order to update the OS information stored in the storage unit 114.

The control unit 116 functions as an arithmetic processing unit and a control unit, and controls overall operations within the suction device 100 according to various programs. The control unit 116 is realized by an electronic circuit such as a CPU (Central Processing Unit) and a microprocessor, for example. In addition, the control unit 116 may include a ROM (Read Only Memory) that stores programs to be used, operation parameters, etc., and a RAM (Random Access Memory) that temporarily stores parameters that change appropriately. The suction device 100 executes various processes based on control by the control unit 116. Feeding power from the power source unit 111 to other components, charging the power source unit 111, detecting information by the sensor unit 112, notification of information by the notification unit 113, and information by the storage unit 114. Storage and reading, and transmission and reception of information by the communication unit 115 are examples of processing controlled by the control unit 116. Other processes performed by the suction device 100, such as input of information to each component and processing based on information output from each component, are also controlled by the control unit 116.

The receiving portion 140 includes 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 receiving portion 140 includes an opening 142 that communicates the internal space 141 to the outside, and accommodates the stick-shaped substrate 150 inserted into the internal space 141 through the opening 142. For example, the accommodating part 140 is a cylindrical body with an opening 142 and a bottom part 143 at both ends, and defines a column-shaped internal space 141. The receiving portion 140 is configured to have an inner diameter smaller than the outer diameter of the stick-shaped substrate 150 in at least a portion of the height direction of the cylindrical body, and holds the stick-shaped substrate 150 inserted into the internal space 141 around the outer circumference. The stick-type substrate 150 can be held and supported by applying pressure from thereon. The receiving portion 140 also has a function of defining a flow path for air passing through the stick-shaped substrate 150. The air inlet hole, which is the inlet of air into this flow path, is disposed, for example, in the bottom portion 143. On the other hand, the air outlet hole, which is the outlet of air from this flow path, is the opening 142.

The stick-shaped substrate 150 is a stick-shaped member. The stick-shaped substrate 150 includes a substrate portion 151 and an opening portion 152.

The substrate 151 contains an aerosol source. The aerosol source is atomized by heating and an aerosol is generated. The base portion 151 may further include a flavor source that imparts flavor components to the aerosol. The aerosol source may be one derived from tobacco, for example, shredded tobacco or a processed product obtained by molding tobacco raw materials into granules, sheets, or powders. Additionally, the aerosol source may include a non-tobacco source made from plants other than tobacco (for example, mint and herbs, etc.). As an example, the aerosol source may contain a flavor component such as menthol. When the suction device 100 is a medical inhaler, the aerosol source may include a drug to be inhaled by the patient. Additionally, the aerosol source is not limited to solids, and may be, for example, polyhydric alcohols such as glycerin and propylene glycol, and liquids such as water. At least a part of the base material 151 is accommodated in the internal space 141 of the receiving part 140 in a state in which the stick-shaped base material 150 is held in the receiving part 140 .

The intake portion 152 is a member that is held by the user during suction. At least a portion of the intake portion 152 protrudes from the opening 142 while the stick-shaped substrate 150 is held in the receiving portion 140 . Then, when the user bites the intake portion 152 protruding from the opening 142 and sucks, air flows into the interior of the receiving portion 140 from an air inlet hole (not shown). The introduced air passes through the internal space 141 of the receiving unit 140, that is, passes through the base unit 151, and reaches the inside of the user's mouth along with the aerosol generated from the base unit 151.

Additionally, the stick-shaped substrate 150 includes a susceptor 161. The susceptor 161 generates heat by electromagnetic induction. The susceptor 161 is made of a conductive material such as metal. As an example, the susceptor 161 is a metal piece. Here, the susceptor 161 is disposed thermally close to the aerosol source. That the susceptor 161 is thermally close to the aerosol source refers to the fact that the susceptor 161 is disposed at a location where heat generated in the susceptor 161 is transmitted to the aerosol source. For example, the susceptor 161 is contained in the base portion 151 together with the aerosol source, and is surrounded by the aerosol source. This configuration makes it possible to efficiently use the heat generated from the susceptor 161 to heat the aerosol source. Additionally, the susceptor 161 may not be contacted from the outside of the stick-shaped substrate 150. For example, the susceptor 161 may be distributed in the center of the stick-shaped base material 150 and not in the vicinity of the outer periphery.

The electromagnetic induction source 162 inductively heats the susceptor 161. The electromagnetic induction source 162 generates a fluctuating magnetic field (more specifically, an alternating magnetic field) when an alternating current is supplied. The electromagnetic induction source 162 is disposed at a position where the internal space 141 of the receiving part 140 overlaps the generated fluctuating magnetic field. The electromagnetic induction source 162 is made of, for example, a coil-shaped conductor and is arranged to be wound around the outer periphery of the receiving portion 140. Therefore, when a fluctuating magnetic field is generated while the stick-shaped substrate 150 is accommodated in the receiving portion 140, an eddy current is generated in the susceptor 161 and Joule heat is generated. Then, the aerosol source contained in the stick-shaped substrate 150 is heated and atomized by this Joule heat, thereby generating an aerosol. As an example, when the sensor unit 112 detects that a predetermined user input has been made, power may be supplied and an aerosol may be generated. After that, when the sensor unit 112 detects that a predetermined user input has been made, power supply may be stopped. As another example, power may be supplied and aerosol may be generated during a period when the sensor unit 112 detects suction by the user.

Additionally, the susceptor 161 is an example of a heat source that heats the aerosol source. An aerosol can be generated by combining the suction device 100 and the stick-type substrate 150. Accordingly, the combination of the suction device 100 and the stick-shaped substrate 150 may be considered an aerosol generating system.

<2. Technical Features>

(1) Heating profile

The control unit 116 controls the temperature at which the aerosol source contained in the stick-shaped substrate 150 is heated, that is, the temperature of the susceptor 161. Specifically, the control unit 116 controls the operation of the electromagnetic induction source 162 based on the heating profile. The heating profile is control information for controlling the temperature at which the aerosol source is heated, that is, the temperature of the susceptor 161. As an example, the heating profile may include a target temperature of the susceptor 161 (hereinafter also referred to as target temperature). The target temperature may change depending on the elapsed time from the start of heating, and in this case, the heating profile includes information defining the time series transition of the target temperature. As another example, the heating profile may include parameters (hereinafter also referred to as power supply parameters) that define the supply of power to the electromagnetic induction source 162. Power supply parameters include, for example, ON/OFF of power supply to the electromagnetic induction source 162.

The control unit 116 controls the power supply to the electromagnetic induction source 162 so that the actual temperature (hereinafter also referred to as room temperature) of the susceptor 161 changes in parallel with the time series change of the target temperature specified in the heating profile. do. This results in the generation of an aerosol as planned by the heating profile. The heating profile is typically designed so that the flavor (hereinafter also referred to as taste) experienced by the user when the user inhales the aerosol generated from the stick-shaped substrate 150 is optimal. Therefore, the taste can be optimized by controlling the power supply to the electromagnetic induction source 162 based on the heating profile.

The temperature of the susceptor 161 can be estimated based on the electrical resistance value of a driving circuit such as an LC circuit including the electromagnetic induction source 162. This is because there is an extremely monotonous relationship between the electrical resistance value of the drive circuit and the temperature of the susceptor 161. Accordingly, the control unit 116 estimates the electrical resistance value of the driving circuit based on information on the direct current power supplied to the driving circuit. Then, the control unit 116 estimates the temperature of the susceptor 161 based on the electrical resistance value of the drive circuit. In another example, the temperature of the susceptor 161 may be measured by a temperature sensor such as a thermistor installed near the receiving portion 140.

The heating profile may include one or more combinations of an elapsed time after starting heating and a target temperature to be reached at that elapsed time. Then, the control unit 116 controls the temperature of the susceptor 161 based on the difference between the current room temperature and the target temperature in the heating profile corresponding to the elapsed time after starting the current heating. Temperature control of the susceptor 161 can be realized by, for example, known feedback control. In feedback control, the control unit 116 just controls the power supplied to the electromagnetic induction source 162 based on the difference between the actual temperature and the target temperature. The feedback control may be, for example, PID control (Proportional-Integral-Differential Controller). Alternatively, the control unit 116 may perform simple ON-OFF control. For example, the control unit 116 may supply power to the electromagnetic induction source 162 until the room temperature reaches the target temperature, and may stop supplying power to the electromagnetic induction source 162 when the room temperature reaches the target temperature. .

The control unit 116 can supply power from the power supply unit 111 to the electromagnetic induction source 162 in the form of a pulse by pulse width modulation (PWM) or pulse frequency modulation (PFM). In this case, the control unit 116 can control the temperature of the susceptor 161 by adjusting the duty ratio of the power pulse through feedback control.

The time interval from the start of the process of generating an aerosol using the stick-shaped substrate 150 to the end, more specifically, the time interval during which the electromagnetic induction source 162 operates based on the heating profile, is hereinafter referred to as heating. Also called a session. The timing of the heating session is the timing at which heating based on the heating profile is initiated. The end of the heating session is the timing at which a sufficient amount of aerosol is no longer produced. The heating session consists of a preheating period in the first half and a puffable period in the second half. The puffable period is a period during which a sufficient amount of aerosol is assumed to be generated. The preheating period is the period from when induction heating is started until the user can inhale the aerosol, that is, until the puffable period begins. Heating performed in the preheating period is also called preheating.

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

[Table 1]

As shown in Table 1, the heating profile may be divided into a plurality of periods, and the time series change of the target temperature and the time series change of the power supply parameter may be defined in each period. In the example shown in Table 1, the heating profile is divided into a total of 10 periods from STEP 0 to STEP 9. In each STEP, the time series trend of the target temperature and the time series trend of the power supply parameters are defined. STEP specified in the heating profile is an example of a unit period in this embodiment.

As shown in Table 1, the heating profile includes information for controlling the temperature of the susceptor 161 in each of the initial temperature increase period, the intermediate temperature decrease period, the re-heating period, and the heating end period. The initial temperature increase period is an example of the first period in which the temperature of the susceptor 161 increases after the start of heating. The initial temperature increase period consists of STEP 0 to STEP 2. The intermediate temperature drop period is an example of a second period during which the temperature of the susceptor 161 decreases following the initial temperature rise period. The mid-temperature cooling period consists of STEP 3. The re-heating period is an example of a third period in which the temperature of the susceptor 161 rises following the intermediate temperature lowering period. The reheating period consists of STEP 4 to STEP 8. The heating end period follows the reheating period and is a period in which the temperature of the susceptor 161 decreases. The heating end period consists of STEP 9. By having the heating session sequentially include an initial temperature increase period, an intermediate temperature decrease period, and a reheating period, as described later, the preheating period is shortened, rapid consumption of the aerosol source is prevented, and the taste delivered to the user is optimized. It becomes possible.

In STEP 1 to STEP 9, time control is implemented. Time control is control that terminates a STEP by triggering the passage of a predetermined time (that is, the duration time set for each STEP). Additionally, when time control is implemented, the rate of change of the temperature of the susceptor 161 may be controlled so that the temperature of the susceptor 161 reaches the target temperature at the end of the duration. In addition, when time control is implemented, the temperature of the susceptor 161 reaches the target temperature during the duration time, and then the temperature of the susceptor 161 maintains the target temperature until the duration time elapses. The temperature of the susceptor 161 may be controlled.

On the other hand, in STEP 0, time control is not implemented. If time control is not implemented, the STEP is terminated as a trigger when the temperature of the susceptor 161 reaches a predetermined temperature (that is, the target temperature set for each STEP). Therefore, the duration of STEP 0 expands depending on the temperature increase rate.

The change in temperature of the susceptor 161 when the control unit 116 performs temperature control according to the heating profile shown in Table 1 will be described with reference to FIG. 2. FIG. 2 is a graph 20 showing an example of the temperature transition of the susceptor 161 when temperature control is performed based on the heating profile shown in Table 1. The horizontal axis of the graph 20 is time (seconds). The vertical axis of the graph 20 is the temperature of the susceptor 161. Line 21 represents the change in temperature of the susceptor 161. As shown in FIG. 2, the temperature of the susceptor 161 is trending similarly to the trend of the target temperature specified in the heating profile. Hereinafter, an example of a heating profile will be described with reference to Table 1 and FIG. 2.

As shown in Table 1 and FIG. 2, in the initial temperature increase period, the temperature of the susceptor 161 increases or is maintained. Specifically, in STEP 0, the temperature of the susceptor 161 rises from the initial temperature to 350°C. The initial temperature is the temperature of the susceptor 161 at the start of heating. In STEP 0, time control is not implemented. Accordingly, STEP 0 is terminated by triggering that the temperature of the susceptor 161 reaches 350°C. In the example shown in FIG. 2, STEP 0 ends in 20 seconds. Thereafter, in STEP 1 and STEP 2, the temperature of the susceptor 161 is maintained at 350°C. The preliminary heating period ends with the end of STEP 1, and the puffable period begins with the start of STEP 2. In the initial temperature increase period, by raising the temperature of the susceptor 161 to a high temperature at once, it becomes possible to end the preheating early and start the puffable period early.

As shown in Table 1 and FIG. 2, the temperature of the susceptor 161 decreases during the intermediate temperature drop period. Specifically, in STEP 3, the temperature of the susceptor 161 decreases to 300°C. By temporarily lowering the temperature of the susceptor 161 during the mid-temperature drop period, problems such as rapid consumption of aerosol sources and excessively strong flavor delivered to the user can be prevented, making it possible to improve the quality of the user's puff experience. . Additionally, in STEP 3, power supply to the electromagnetic induction source 162 is turned OFF. Therefore, it becomes possible to reduce the temperature of the susceptor 161 as quickly as possible.

As shown in Table 1 and FIG. 2, in the reheating period, the temperature of the susceptor 161 increases or is maintained. In detail, from STEP 4 to STEP 7, the temperature of the susceptor 161 gradually rises to 320°C. In this way, control information spanning multiple STEPs may be defined. Afterwards, in STEP 8, the temperature of the susceptor 161 is maintained at 320°C. By raising the temperature of the susceptor 161, which decreased during the mid-temperature drop period, again during the re-heating period, excessive temperature drop of the aerosol source and subsequent deterioration of the flavor delivered to the user are prevented, thereby improving the quality of the user's puff experience. It becomes possible.

As shown in Table 1 and FIG. 2, the temperature of the susceptor 161 decreases in the heating termination period. In detail, in STEP 9, the temperature of the susceptor 161 decreases. In STEP 9, while the duration is specified, the target temperature is not. Therefore, STEP 9 ends with the end of the duration as the trigger. In STEP 9, a sufficient amount of aerosol can be generated by the residual heat of the stick-shaped substrate 150. Therefore, in this example, the puffable period, i.e., the heating session, ends with the end of STEP 9. Additionally, in STEP 9, power supply to the electromagnetic induction source 162 is turned OFF. By providing a heating end period at the end of the puffable period, it becomes possible to suppress power consumption.

The notification unit 113 may notify the user of information indicating the timing at which preheating ends. For example, the notification unit 113 notifies information indicating the end of the preheating before the end of the preheating, or notifies information indicating the end of the preheating at the timing when the preheating ends. Notification to the user can be performed, for example, by lighting an LED or vibrating it. The user can refer to this notification and perform a puff immediately after the end of the preliminary heating.

Similarly, the notification unit 113 may notify the user of information indicating the timing at which the puffable period ends. For example, the notification unit 113 notifies information indicating the end of the puffable period before the puffable period ends, or notifies information indicating that the puffable period has ended at the timing when the puffable period ends. . Notification to the user can be performed, for example, by lighting an LED or vibrating it. The user can refer to this notification and perform puffs until the puffable period ends.

In addition, the heating profile described above is only an example, and various other examples are conceivable. As an example, the number of STEPs, the duration of each STEP, and the target temperature may be changed as appropriate. As another example, in STEP 4, the temperature of the susceptor 161 may be maintained at 300°C.

(2) Technical challenges

Referring to FIG. 3, the technical problem of the suction device 100 according to this embodiment will be described.

FIG. 3 is a graph for explaining the technical problems of the suction device 100 according to this embodiment. The horizontal axis of the graph 30 is time. The vertical axis of the graph 30 is temperature. The graph 30 includes a line 31 showing the time series change of the temperature of the susceptor 161 and a line 32 showing the time series change of the temperature of the aerosol source. The user performs a second puff (hereinafter also referred to as the previous puff) between time t _2S and time t _2E , and then performs a first puff (hereinafter referred to as the current puff) between time t _1S and time t _1E . (also referred to as) is said to have been performed. Temperature h _T is the target temperature of the susceptor 161. In addition, in this specification, when the temperature decrease accompanying the puff does not occur, the temperature of the aerosol source is assumed to match the temperature of the susceptor 161. That is, as shown in the lines 31 and 32, while the puff is performed, the temperature of the susceptor 161 and the temperature of the aerosol source are set to the target temperature h _T of the susceptor 161. Maintaining.

As shown in the line 32, when the user puffs, the temperature of the stick-shaped substrate 150, especially the temperature of the aerosol source, decreases significantly. This is because the warm air in the internal space 141 is sucked in by the user along with the aerosol, and new cool air flows into the internal space 141 to cool the stick-shaped base material 150.

When the user puffs, the temperature of not only the aerosol source but also the susceptor 161 may decrease. However, the susceptor 161 has characteristics that make it less susceptible to disturbance. In other words, the susceptor 161 has characteristics that make it easy to become warm and difficult to cool down. Therefore, as shown in the line 31, even if the user puffs, the temperature of the susceptor 161 can be maintained at the target temperature _hT . That is, as shown in lines 31 and 32, when the user puffs, a gap occurs between the temperature of the susceptor 161 and the temperature of the aerosol source.

As shown in line 32, when puffs are performed continuously at short intervals, the puffs may be initiated before the temperature of the aerosol source completely returns to its original state. For example, the previous puff was started while the temperature of the aerosol source did not decrease, whereas the current puff was started with the temperature of the aerosol source lowered. Accordingly, as shown in line 32, the temperature of the aerosol source in the period t _1S to t _1E corresponding to the current puff is lowered compared to the temperature of the aerosol source in the period t _2S to t _2E corresponding to the previous puff. As a result, the taste delivered to the user from the current puff may be deteriorated compared to the taste delivered to the user from the previous puff. This is because if the temperature of the aerosol source decreases, the amount of aerosol produced may decrease or the flavor imparted to the aerosol may decrease. In this way, there is a risk that taste deterioration during continuous puffing may be caused by an excessive decrease in the temperature of the aerosol source during continuous puffing.

Therefore, in this embodiment, the temperature of the susceptor 161 is temporarily increased during continuous puffing. With such a configuration, it becomes possible to prevent excessive temperature decrease of the aerosol source during continuous puffing and to prevent taste deterioration during continuous puffing.

(3) Temperature control during continuous puff

Referring to FIG. 4, temperature control during continuous puffing by the suction device 100 according to the present embodiment will be described.

FIG. 4 is a graph for explaining temperature control during continuous puffing by the suction device 100 according to the present embodiment. The horizontal axis of the graph 40 is time. The vertical axis of the graph 40 is temperature. The graph 40 includes a line 41 showing the time series change of the temperature of the susceptor 161 and a line 42 showing the time series change of the temperature of the aerosol source. The user starts from time t _2S . The second puff (hereinafter also referred to as the previous puff) is performed from time t _2E , and then the first puff (hereinafter also referred to as the current puff) is performed between time t _1S and time t _1E . . Temperature h _T is the target temperature of the susceptor 161.

When a puff is detected, the control unit 116 records the time at which the puff was detected in the storage unit 114 and controls the temperature of the susceptor 161 based on the recorded time. For example, the control unit 116 responds to a change in the flow rate of air flowing into the receiving part 140 detected by a flow sensor, a change in the amount of power supplied to the electromagnetic induction source 162, or a change in the temperature of the susceptor 161. Based on this, puffs can be detected. The control unit 116 controls power supply to the electromagnetic induction source 162 by controlling the temperature of the susceptor 161. For example, the control unit 116 adjusts the duty ratio of the power pulse supplied to the electromagnetic induction source 162.

When a puff (i.e., this time's puff) through which the user inhales an aerosol generated from an aerosol source is performed, the control unit 116 controls the susceptor (i.e., the current puff) based on information on the previous puff (i.e., the previous puff). 161) to control the temperature. For example, when the current puff is performed, the control unit 116 performs control to increase the temperature of the susceptor 161 based on the information of the previous puff. In particular, the control unit 116 increases the temperature of the susceptor 161 at least part of the period during which the current puff is being detected. As shown in the line 41, the control unit 116 controls the current puff period from t _1S. Throughout the final period t _1E , the temperature of the susceptor 161 may be raised. Of course, this puff's time t _1S and The timing of the period for raising the temperature of the susceptor 161 may be different. Additionally, the end time t _1E of this puff may be different from the end time of the period for raising the temperature of the susceptor 161. The control unit 116 increases the amount of power supplied to the electromagnetic induction source 162 in order to increase the temperature of the susceptor 161. At this time, the control unit 116 may increase the duty ratio of the power pulse supplied to the electromagnetic induction source 162. Comparing the line 32 shown in FIG. 3 and the line 42 shown in FIG. 4, by performing the above control, an excessive decrease in the temperature of the aerosol source in the period t _1S to t _1E corresponding to the current puff is suppressed. there is. This makes it possible to prevent taste deterioration during continuous puffs, and more specifically, taste deterioration in the current puff performed at a short interval from the previous puff.

The control unit 116 controls the temperature of the susceptor 161 based on the interval Δt between the current puff and the previous puff. For example, the control unit 116 performs control to increase the temperature of the susceptor 161 based on the interval Δt between the current puff and the previous puff. An example of the interval Δt between the current puff and the previous puff is the interval from the end t _2E of the previous puff to the time t _1S of the current puff. The temperature of the aerosol source decreases with the puff, rises over time after the puff ends, and returns to the original temperature. Therefore, the shorter the interval Δt between the current puff and the previous puff, the greater the decrease in the temperature of the aerosol source from the target temperature h _T at the time t _1S of the current puff. On the other hand, the longer the interval Δt between the current puff and the previous puff, the smaller the decrease in the temperature of the aerosol source from the target temperature h _T at the time t _1S of the current puff. In this regard, according to this configuration, the temperature of the susceptor 161 and the temperature of the aerosol source are raised according to the decrease in the temperature of the aerosol source at the time t _1S of the current puff from the target temperature h _T. It becomes possible.

Specifically, the control unit 116 may increase the temperature of the susceptor 161 when the interval Δt between the current puff and the previous puff is less than a predetermined threshold value. An example of a predetermined threshold value is the time assumed to be taken for the temperature of the aerosol source, which has decreased due to the puff, to return to its original state. In this case, the control unit 116 increases the temperature of the aerosol source by raising the temperature of the susceptor 161 only when the temperature of the aerosol source at the time t _1S of the current puff has decreased due to the influence of the previous puff. I order it. On the other hand, the control unit 116 does not increase the temperature of the susceptor 161 when the temperature of the aerosol source at the time t _1S of the current puff has not decreased due to the influence of the previous puff. According to this configuration, the temperature of the susceptor 161 can be increased only when continuous puffs are performed at intervals narrow enough to cause taste deterioration. Therefore, it becomes possible to suppress power consumption.

Additionally, the control unit 116 may increase the temperature of the susceptor 161 significantly as the interval Δt between the current puff and the previous puff becomes shorter. On the other hand, the control unit 116 may increase the temperature of the susceptor 161 to a smaller extent as the interval Δt between the current puff and the previous puff is longer. According to this configuration, it becomes possible to increase the temperature of the susceptor 161 without excessive or insufficient.

As described above, the control unit 116 controls the temperature of the susceptor 161 based on the heating profile. However, as shown in the line 41, the control unit 116 sets the temperature of the susceptor 161 to the target temperature h _T when the puff is performed this time. It is controlled so that the temperature h _T ' is raised by the temperature Δh corresponding to the information of the previous puff. In detail, the control unit 116 sets the temperature of the susceptor 161 to the target temperature h _T when the interval Δt between the previous puff and the current puff is less than a predetermined threshold value. Δh is controlled to reach the raised temperature h _T '. However, the control unit 116 sets Δh larger as the interval Δt between the previous puff and the current puff is shorter, and sets Δh smaller as the interval Δt between the previous puff and the current puff is longer. According to this configuration, the temperature of the susceptor 161 is lower than the target temperature h _T By reaching a high temperature _hT ', excessive temperature drop of the aerosol source during continuous puffing can be prevented. According to this configuration, it becomes possible to provide the user with an optimal taste according to the heating profile while preventing taste deterioration during continuous puffing.

The control unit 116 may control the temperature of the susceptor 161 based on information from the previous puff, especially when a puff is performed during the re-heating period. In other words, the control unit 116 does not need to control the temperature of the susceptor 161 based on the information of the previous puff even if a puff is performed during the initial temperature increase period and the intermediate temperature decrease period. Since the initial temperature increase period is a period in which the temperature of the susceptor 161 rises rapidly and is maintained at a high temperature, the temperature decrease of the aerosol source accompanying the puff is small. Additionally, since the mid-temperature drop period is a period in which the temperature of the susceptor 161 and the temperature of the aerosol source are lowered, there is little need to prevent the temperature of the aerosol source from lowering due to the puff. In contrast, during the re-heating period, the temperature of the susceptor 161 is relatively low and the temperature drop of the aerosol source accompanying the puff is relatively large, so the taste may deteriorate significantly during continuous puffing. In this regard, according to this configuration, it becomes possible to efficiently prevent taste deterioration during continuous puffing only during the re-temperature period during which the taste may significantly deteriorate during continuous puffing.

Hereinafter, the processing flow according to this embodiment will be described with reference to FIG. 5. FIG. 5 is a flowchart showing an example of the flow of processing performed by the suction device 100 according to the present embodiment.

As shown in Fig. 5, first, the control unit 116 determines whether a user operation instructing to start heating has been detected (step S102). An example of a user operation that instructs the start of heating is an operation on the suction device 100, such as operating a switch provided on the suction device 100. Another example of a user operation instructing to start heating is inserting the stick-shaped substrate 150 into the suction device 100.

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

On the other hand, when it is determined that a user operation instructing to start heating is detected (step S102: YES), the control unit 116 starts heating based on the heating profile (step S104). For example, the control unit 116 controls the duty ratio of the power supplied to the electromagnetic induction source 162 so that the room temperature of the susceptor 161 changes similar to the time series change of the target temperature specified in the heating profile.

Next, the control unit 116 determines whether the temperature reheating period has transitioned (step S106). If it is determined that the transition to the re-heating period has not occurred (step S106: NO), the control unit 116 waits until the transition to the re-heating period.

On the other hand, when it is determined that the temperature has moved to the reheating period (step S106: YES), the control unit 116 determines whether the puff has been performed (step S108).

When it is determined that a puff has been performed (step S108), the control unit 116 determines that the interval between the puff detected last time (i.e., previous puff) and the puff detected in step S108 (i.e., current puff) is less than a predetermined threshold value. It is determined whether it is recognized (step S110).

When it is determined that the interval between the previous puff and the current puff is less than a predetermined threshold (step S108: YES), the control unit 116 temporarily increases the temperature of the susceptor 161 (step S112). For example, in the example shown in FIG. 4, the control unit 116 starts from the time t _1S of the current puff. Throughout the boiling point t _1E , the temperature of the susceptor 161 is raised. After that, the process proceeds to step S114.

If it is determined in step S108 that the puff has not been performed (step S108: NO), the process proceeds to step S114. If it is determined in step S110 that the interval between the previous puff and the current puff is equal to or greater than a predetermined threshold (step S110: NO), the process also proceeds to step S114.

In step S114, the control unit 116 determines whether the termination condition is met (step S114). An example of an end condition is that a predetermined time has elapsed from the start of heating. Another example of an end condition is that the number of puffs from the start of heating reaches a predetermined number.

If it is determined that the end condition is not met (step S114: NO), the process returns to step S108.

On the other hand, when it is determined that the termination condition is met (step S114: YES), the control unit 116 ends heating based on the heating profile (step S116). After that, processing ends.

<3. Supplement>

Although preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to these examples. It is clear that those skilled in the art in the technical field to which the present invention pertains will be able to come up with various changes or modifications within the scope of the technical idea described in the claims, and of course these will also be covered by this invention. It is understood to fall within the technical scope of the invention.

(1) First modification example

The control unit 116 may control the temperature of the susceptor 161 based on the suction amount from the previous puff. The suction amount is the total amount of fluid sucked in by the user when puffing. The amount of suction is calculated or estimated based on the flow rate of air detected by, for example, a flow rate sensor. Alternatively, the length of the puff (e.g., the length of time from the time t _2S of the previous puff to the end t _2E of the puff) may be simply used as the suction amount. As the amount of suction from the previous puff increases, the stick-shaped base material 150 is cooled by more air, so the decrease in the temperature of the aerosol source at the time t _1S of the current puff from the target temperature h _T is greater. On the other hand, the smaller the suction amount in the previous puff, the smaller the stick-shaped substrate 150 is cooled by less air, so the decrease in the temperature of the aerosol source at the time t _1S of the current puff from the target temperature h _T is smaller. In this regard, according to this configuration, the temperature of the susceptor 161 and the temperature of the aerosol source are raised according to the decrease in the temperature of the aerosol source at the time t _1S of the current puff from the target temperature h _T. It becomes possible.

Specifically, the control unit 116 may increase the temperature of the susceptor 161 significantly as the amount of suction from the previous puff increases. On the other hand, the control unit 116 may increase the temperature of the susceptor 161 to a smaller extent as the amount of suction from the previous puff decreases. According to this configuration, it becomes possible to increase the temperature of the susceptor 161 without excessive or insufficient.

Additionally, the control unit 116 may set the predetermined threshold value compared with the interval Δt between the previous puff and the current puff, based on the suction amount in the previous puff. For example, the control unit 116 may increase the predetermined threshold value as the amount of suction in the previous puff increases, and may decrease the predetermined threshold value as the amount of suction in the previous puff decreases. The temperature of the aerosol source decreases significantly as the amount of suction increases, and the time it takes for it to rise and return to its original state becomes longer. Therefore, even if the distance Δt between the previous puff and the current puff is the same, if the suction amount in the previous puff is different, the amount of decrease in the temperature of the aerosol source at the time t _1S of the current puff from the target temperature h _T is different. In this regard, according to this configuration, the temperature of the susceptor 161 can be increased only in cases where deterioration of taste in the current puff is assumed based on the suction amount in the previous puff.

(2) Second modification example

The control unit 116 may control the temperature of the susceptor 161 based on the environmental temperature. The environmental temperature is the temperature of the environment in which the suction device 100 operates. An example of environmental temperature is air temperature. The environmental temperature can be detected, for example, by a temperature sensor. When the environmental temperature is low, the temperature of the new air flowing into the internal space 141 with the puff is low, so it can be considered that the temperature decrease of the aerosol source accompanying the puff is large. On the other hand, when the environmental temperature is high, the temperature of the new air flowing into the internal space 141 with the puff is high, so it can be considered that the temperature decrease of the aerosol source accompanying the puff is small. Accordingly, the control unit 116 increases the temperature of the susceptor 161 significantly as the environmental temperature decreases. Meanwhile, the control unit 116 increases the temperature of the susceptor 161 to a smaller extent as the environmental temperature increases. According to this configuration, it becomes possible to appropriately prevent taste deterioration during continuous puffing depending on the extent of temperature decrease of the aerosol source corresponding to the environmental temperature.

Additionally, the control unit 116 may set the predetermined threshold value compared with the interval Δt between the previous puff and the current puff, based on the environmental temperature. For example, the control unit 116 may increase the predetermined threshold value as the environmental temperature decreases, and may decrease the predetermined threshold value as the environmental temperature increases. The temperature of the aerosol source decreases significantly as the environmental temperature decreases, and the time it takes for it to rise and return to the original temperature becomes longer. Therefore, even if the distance Δt between the previous puff and the current puff is the same, if the environmental temperature is different, the extent of decrease of the temperature of the aerosol source from the target temperature h _T at the time t _1S of the current puff is different. In this regard, according to this configuration, the temperature of the susceptor 161 can be increased only in cases where taste deterioration of the current puff is assumed based on the environmental temperature.

(3) Third modification example

The control unit 116 may control the temperature of the susceptor 161 based on information about one or more third puffs performed prior to the previous puff. Examples of information on the third puff include the time when the third puff was performed, the interval between the third puff and the previous puff or this puff, or the amount of suction from the third puff. For example, as the number of puffs is performed at short intervals, the temperature of the aerosol source decreases cumulatively. Therefore, for example, the control unit 116 may increase the temperature increase of the susceptor 161 when the current puff is detected, as the number of puffs performed in the past at intervals less than a predetermined threshold increases. According to this configuration, it is possible to prevent taste deterioration of the current puff by taking into account the influence of the cumulative temperature decrease of the aerosol source due to puffs performed multiple times at short intervals.

(4) Other modifications

The temperature control of the susceptor 161 explained in the above embodiments and modifications may be combined appropriately. For example, the control unit 116 based on at least two of the interval between the previous puff and the current puff, the amount of suction in the previous puff, information on one or more third puffs performed prior to the previous puff, or environmental temperature. , the temperature of the susceptor 161 during this puff may be controlled. As a specific example, the control unit 116 does not increase the temperature of the susceptor 161 at the time of the current puff if the amount of suction in the previous puff is small even if the interval between the previous puff and the current puff is less than a predetermined threshold value. You don't have to. According to this configuration, it becomes possible to increase the effect of preventing taste deterioration during continuous puffing compared to the case where the temperature control is performed singly.

In the above embodiment, an example has been described where the control unit 116 uses the interval from the end t _2E of the previous puff to the timing t _1S of the current puff as the interval between the current puff and the previous puff. However, the present invention does not apply to such an example. It is not limited to The control unit 116 may use the interval from the timing t _2S of the previous puff to the timing t _1S of the current puff as the interval between the current puff and the previous puff.

In the above embodiment, an example in which the susceptor 161 is contained in the stick-shaped substrate 150 has been described, but the present invention is not limited to this example. The susceptor 161 may be provided in the suction device 100. As an example, the suction device 100 may include a susceptor 161 disposed outside the internal space 141. Specifically, the accommodating portion 140 may be made of a material having conductivity and magnetism and may function as the susceptor 161. Since the receiving portion 140 as the susceptor 161 is in contact with the outer periphery of the base portion 151, it can be thermally close to the aerosol source contained in the base portion 151. As another example, the suction device 100 may include a susceptor 161 disposed inside the internal space 141. Specifically, the susceptor 161 configured in the shape of a blade may be arranged so as to protrude from the bottom 143 of the accommodating portion 140 into the internal space 141. When the stick-shaped substrate 150 is inserted into the internal space 141 of the receiving portion 140, the blade-shaped susceptor 161 is inserted into the substrate portion 151 of the stick-shaped substrate 150, thereby forming a stick. It is inserted into the interior of the mold base 150. For this reason, the blade-shaped susceptor 161 can be thermally close to the aerosol source contained in the base portion 151.

In the above embodiment, an example in which the aerosol source is heated by the susceptor 161 subjected to induction heating has been described, but the present invention is not limited to this example. The suction device 100 may include a heat-generating resistor that generates heat through electrical resistance when energized, and the aerosol source contained in the stick-shaped substrate 150 may be heated by the heat-generating resistor. In this case, the suction device 100 controls the temperature of the heating resistor based on the heating profile. Additionally, the suction device 100 performs control to increase the temperature of the heating resistor during the current puff, based on information about the previous puff.

Additionally, a series of processes by each device described in this specification may be realized using any of software, hardware, or a combination of software and hardware. Programs constituting software are pre-stored, for example, in a recording medium (specifically, a non-transitory storage medium readable by a computer) provided inside or outside each device.
