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 given the same reference numerals, thereby omitting redundant description.

<1. Configuration example of suction device>

A suction device is a device that produces a substance that is sucked in by a user. Below, it will be explained that the substance generated by the suction device is an aerosol. In addition, the substance generated by the suction device may be gas.

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

The power supply unit 111 accumulates power. Then, the power supply unit 111 supplies power to each component of the suction device 100 based on control by the control unit 116. The power supply unit 111 may be configured by, for example, a rechargeable battery such as a lithium-ion secondary battery.

The sensor unit 112 acquires various information regarding the suction device 100. 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, and acquires a value according to suction by the user. 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.

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

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

The communication unit 115 is a communication interface that enables communication based on any wired or wireless communication standard. As such a communication standard, for example, Wi-Fi (registered trademark), Bluetooth (registered trademark), etc. may be adopted.

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.

The holding portion 140 has an internal space 141 and holds the stick-shaped base material 150 while accommodating a part of the stick-shaped base material 150 in the internal space 141 . The holding portion 140 has an opening 142 that communicates the inner space 141 to the outside, and a stick-shaped base material 150 inserted into the inner space 141 from the opening 142. Pussy. For example, the holding part 140 is a cylindrical body with an opening 142 and a bottom 143 as its bottom, and defines a column-shaped internal space 141 ( Determine. The holding portion 140 also has a function of defining a flow path for air supplied to the stick-shaped substrate 150. The air inlet hole, which is the inlet of air into this flow path, is disposed at the bottom 143, for example. 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 includes a substrate portion 151 and an inlet portion 152. The substrate 151 contains an aerosol source. Aerosol sources are, for example, polyhydric alcohols such as glycerin and propylene glycol, and liquids such as water. The aerosol source may contain flavor components derived from tobacco or non-tobacco. When the suction device 100 is a medical inhaler such as a nebulizer, the aerosol source may include a drug. Additionally, in this configuration example, the aerosol source is not limited to liquid and may be solid. When the stick-shaped base material 150 is held in the holding portion 140, at least a portion of the base portion 151 is accommodated in the internal space 141, and at least a portion of the intake portion 152 is in the opening 142. protrudes from Then, when the user bites and inhales the mouth opening 152 protruding from the opening 142, air flows into the internal space 141 from an air inlet hole (not shown), and is together with the aerosol generated from the base member 151. reaches the user's mouth.

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

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

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

As an example, the heating unit 121 may be configured in a blade shape and may be arranged to protrude from the bottom 143 of the holding unit 140 into the internal space 141. In that case, the blade-shaped heating part 121 is inserted into the base portion 151 of the stick-shaped substrate 150 and heats the base portion 151 of the stick-shaped substrate 150 from the inside. As another example, the heating part 121 may be arranged to cover the bottom part 143 of the holding part 140. In addition, the heating unit 121 includes a first heating unit covering the outer periphery of the holding unit 140, a blade-shaped second heating unit, and a third heating unit covering the bottom portion 143 of the holding unit 140. Among the parts, it may be composed of a combination of two or more parts.

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

Additionally, the means for atomizing the aerosol source is not limited to heating by the heating unit 121. For example, the means for atomizing the aerosol source may be induction heating.

The suction device 100 and the stick-shaped substrate 150 cooperate to generate an aerosol that is sucked in by the user. Therefore, the combination of the suction device 100 and the stick-shaped substrate 150 may be recognized as an aerosol generating system.

＜2. First embodiment>

(1) Circuit configuration

FIG. 2 is a block diagram showing a partial circuit configuration of the suction device 100 according to the present embodiment. As shown in FIG. 2, the suction device 100 according to the present embodiment further includes a vibration element 171 and a measurement unit 172.

The vibration element 171 is a device that vibrates. The vibration element 171 may be, for example, an eccentric motor. The vibration element 171 vibrates when power is supplied. The vibration element 171 is an example of an operating unit different from the heating unit 121 that operates using power supplied from the power supply unit 111. The vibration element 171 is included in the notification unit 113 and vibrates to notify the user of various types of information.

The measuring unit 172 measures a physical quantity corresponding to the temperature of the heating unit 121. Hereinafter, the physical quantity measured by the measurement unit 172 is also referred to as a measured value. The measurement unit 172 outputs the measured value to the control unit 116. An example of a measured value is the resistance value of the heating unit 121. The resistance value of the heating unit 121 (more specifically, the heating resistor constituting the heating unit 121) changes depending on the temperature of the heating resistor. Additionally, the resistance value of the heating resistor can be estimated by, for example, measuring the voltage drop across the heating resistor. The voltage drop across the heating resistor can be obtained by measuring the potential difference applied to the heating resistor. That is, the measuring unit 172 may measure the voltage drop in the heating unit 121 and measure the resistance value of the heating unit 121 based on the measured voltage drop.

The power supply unit 111 supplies power to the vibration element 171 and the heating unit 121. The power supply unit 111 also includes a circuit that switches the power supply source. Based on control by the control unit 116, power supply from the power source unit 111 to the vibration element 171 is switched ON/OFF and power supply from the power source unit 111 to the heating unit 121 is switched ON/OFF.

The control unit 116 controls power supply by the power supply unit 111. Specifically, the control unit 116 transmits to the power supply unit 111 a control signal for controlling the power supply source and power supply amount (for example, the duty ratio of the power pulse, etc., which will be described later). As an example, the control unit 116 controls power supply to the heating unit 121 based on the measured value detected by the measurement unit 172. Then, the heating unit 121 uses the power supplied from the power supply unit 111 to heat the stick-shaped substrate 150 (i.e., an aerosol source) to generate an aerosol.

(2) Heating profile

The control unit 116 controls the operation of the heating unit 121 based on the heating settings. Control of the operation of the heating unit 121 is realized by controlling the power supply from the power supply unit 111 to the heating unit 121. The heating setting is information that specifies the time series transition of the target temperature, which is the target temperature of the heating unit 121. Hereinafter, such heating settings are also referred to as heating profiles.

The control unit 116 sets the temperature of the heating unit 121 (hereinafter also referred to as room temperature) corresponding to the measured value measured by the measuring unit 172 to the target temperature specified in the heating profile. The operation of the heating unit 121 is controlled to achieve the same transition. The heating profile is typically designed so that the flavor experienced by the user when the user inhales the aerosol generated from the stick-shaped substrate 150 is optimal. Therefore, by controlling the operation of the heating unit 121 based on the heating profile, the flavor experienced by the user can be optimized.

The heating profile includes one or more combinations of a target temperature and information indicating a timing at which the target temperature should be reached. Then, the control unit 116 controls the operation of the heating unit 121 while switching the target temperature according to the passage of time after starting heating based on the heating profile. In detail, the control unit 116 controls the operation of the heating unit 121 based on the difference between the current room temperature and the target temperature corresponding to the elapsed time after starting heating based on the heating profile. Operation control of the heating unit 121 can be realized by, for example, known feedback control. The feedback control may be, for example, PID control (Proportional-Integral-Differential Controller). The control unit 116 can supply power from the power supply unit 111 to the heating unit 121 in the form of pulses using pulse width modulation (PWM) or pulse frequency modulation (PFM). In that case, the control unit 116 can control the operation of the heating unit 121 by adjusting the duty ratio or frequency of the power pulse in feedback control. Alternatively, the 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 room temperature reaches the target temperature. Then, the control unit 116 stops heating by the heating unit 121 when the room temperature reaches the target temperature, and re-executes heating by the heating unit 121 when the room temperature falls below the target temperature. do.

The period from the start of the process of generating an aerosol using the stick-shaped substrate 150 to the end is hereinafter also referred to as a heating session. In other words, a heating session is a period in which power supply to the heating unit 121 is controlled based on the heating profile. The timing of the heating session is the timing at which heating based on the heating profile is started. The end of the heating session is the timing at which a sufficient amount of aerosol is no longer produced. The heating session includes 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 the start of heating until the start of the puffable period. Heating performed in the preheating period is also called preheating.

The heating profile may include a plurality of periods each with a set target temperature. The target temperature set for a certain period may be controlled to reach the target temperature at an arbitrary timing of the period, or may be controlled to reach the end of the period. In either case, it becomes possible to change the actual temperature of the heating unit 121 in the same way as the change in the target temperature specified in the heating profile.

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

The ideal transition of the resistance value of the heating unit 121 when the control unit 116 performs control according to the heating profile shown in Table 1 will be described with reference to FIG. 3. FIG. 3 is a graph showing the ideal trend of the resistance value of the heating unit 121 when control is performed based on the heating profile shown in Table 1. The horizontal axis of this graph is time (seconds). The vertical axis of this graph represents the resistance value of the heating unit 121. As shown in FIG. 3, the resistance value of the heating unit 121 changes in the same manner as the change in the resistance value corresponding to the target temperature specified in the heating profile.

As shown in Table 1, the heating profile first includes an initial temperature rise period. The initial temperature increase period is a period during which the temperature of the heating unit 121 increases 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 predetermined temperature is a temperature at which the temperature of the stick-shaped substrate 150 is assumed to generate a sufficient amount of aerosol. As shown in FIG. 3, the resistance value of the heating unit 121 rises suddenly to 1.35 Ω during the initial temperature increase period and remains at 1.35 Ω thereafter. As a result, the room temperature of the heating unit 121 rises to 300°C at once during the initial temperature increase period and is maintained at 300°C thereafter. Additionally, the period during which the temperature of the heating unit 121 rises is also referred to as a temperature increase period, and the period during which the temperature of the heating unit 121 is maintained is also referred to as the temperature maintenance period. This configuration makes it possible to end preheating early and start the puffable period early. Additionally, in Figure 3, the preheating period ends 30 seconds after the start of heating.

As shown in Table 1, the heating profile includes an initial temperature increase period followed by an intermediate temperature drop period. The intermediate temperature drop period is a period in which the temperature of the heating unit 121 decreases. The intermediate temperature drop period is comprised of a temperature drop period during which the temperature of the heating unit 121 decreases. As shown in FIG. 3, the resistance value of the heating unit 121 decreases from 1.35 Ω to 1.25 Ω during the intermediate temperature drop period. Accordingly, the room temperature of the heating unit 121 decreases to 250°C during the intermediate temperature reduction period. Even in that case, a sufficient amount of aerosol is generated by the residual heat of the heating unit 121 and the stick-shaped substrate 150. Here, if the heating unit 121 is maintained at a high temperature, the aerosol source contained in the stick-shaped substrate 150 is rapidly consumed, and flavor deterioration, such as the flavor tasted by the user becoming too strong, may occur. there is. In that regard, by providing a temperature lowering period midway, it is possible to avoid such deterioration of flavor and improve the quality of the user's puff experience. Additionally, during the intermediate temperature reduction period, weak power supply to the heating unit 121 may be continued to the extent that the temperature of the heating unit 121 decreases. This is for measuring the resistance value during the mid-temperature drop period.

As shown in Table 1, the heating profile includes an intermediate temperature lowering period followed by a reheating period. The re-heating 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. As shown in FIG. 3, the resistance value of the heating unit 121 is first maintained at 1.25 Ω, then rises to 1.30 Ω, and is maintained at 1.30 Ω thereafter. Accordingly, the room temperature of the heating unit 121 is also maintained at 250°C, then rises to 280°C, and is maintained at 280°C thereafter. In this way, the re-temperature increase period of the heating profile may first include a temperature maintenance period, then include a temperature increase period, and finally include a temperature maintenance period. If the temperature of the heating unit 121 continues to decrease, the stick-shaped base material 150 also decreases in temperature, so the amount of aerosol generated may decrease and the flavor experienced by the user may deteriorate. Additionally, as the heating profile progresses to the latter half, the remaining amount of aerosol source contained in the stick-shaped substrate 150 decreases, so even if heating is continued at the same temperature, the amount of aerosol generated tends to decrease. In that regard, by raising the temperature again in the second half of the heating profile to increase the amount of aerosol production, it is possible to compensate for the decrease in the amount of aerosol production due to the decrease in the remaining amount of the aerosol source. This makes it possible to prevent deterioration of the flavor tasted by the user even in the latter half of the heating profile.

As shown in Table 1, the heating profile ultimately includes a heating termination period. The heating end period is the period following the reheating period and is a period during which heating is not performed. The target temperature does not need to be set. In the heating end period, power supply to the heating unit 121 ends, and the temperature of the heating unit 121 decreases. Even in that case, a sufficient amount of aerosol is generated for a while due to the residual heat of the heating unit 121 and the stick-shaped substrate 150. In the example shown in Figure 3, 340 seconds after the start of heating, the puffable period, that is, the heating session, ends.

(3) Notice

The control unit 116 controls the vibration element 171 and notifies the user of various information. For example, the control unit 116 may notify the user of the timing at which the puffable period starts and the timing at which it ends. Additionally, the control unit 116 may notify the user of a timing (for example, the timing at which power supply to the heating unit 121 ends) a predetermined time before the end of the puffable period. In that case, the user can refer to this notification and perform a puff during the puffable period.

The control unit 116 may control power supply from the power source unit 111 to the vibration element 171 based on the elapsed time after heating by the heating unit 121 starts. As an example, the control unit 116 may vibrate the vibration element 171 30 seconds after the start of heating as a notification of the timing at which the puffable period begins. As another example, the control unit 116 may vibrate the vibration element 171 310 seconds after the start of heating as a notification of a timing a predetermined time before the end of the puffable period. According to this configuration, it becomes possible to easily notify the timing at which the puff should be performed.

The control unit 116 may control power supply from the power supply unit 111 to the vibration element 171 based on the resistance value measured by the measurement unit 172. As an example, the control unit 116 may vibrate the vibration element 171 10 seconds after the resistance value reaches 1.35 Ω in the initial temperature increase period as a notification of the timing at which the puffable period begins. As another example, the control unit 116 notifies the timing a predetermined time before the end of the puffable period, and 60 seconds after the resistance value reaches 1.30 Ω in the re-heating period, the vibration element 171 is activated. You can also vibrate it. It is conceivable that the actual temperature of the heating unit 121 does not change as specified in the heating profile due to the influence of environmental temperature and the like. In this regard, according to this configuration, it becomes possible to notify that the puff should be performed at an appropriate timing according to the change in the room temperature of the heating unit 121.

The control unit 116 may control power supply from the power supply unit 111 to the vibration element 171 based on the number of times the aerosol generated by the heating unit 121 heating the aerosol source is sucked. As an example, the control unit 116 may vibrate the vibration element 171 when the number of puffs after the start of the puffable period reaches a predetermined number as a notification of the timing at which the puffable period ends. As the puff is performed, the aerosol source of the stick-shaped substrate 150 is consumed and depletion becomes faster. In this regard, according to this configuration, it becomes possible to notify the end of the puffable period at an appropriate timing according to the consumption speed of the aerosol source.

(4) Technical challenges

The vibration element 171 and the heating unit 121 share the power supply unit 111. Therefore, depending on the power supply to the vibration element 171, noise may occur in the resistance value of the heating unit 121 measured by the measuring unit 172. This point will be explained with reference to FIGS. 4 to 6.

FIG. 4 is a graph showing an example of the actual change in resistance value of the heating unit 121. The horizontal axis of this graph is time (seconds). The vertical axis of this graph is the resistance value of the heating unit 121 measured by the measuring unit 172. In this graph, when control is performed based on the heating profile shown in Table 1, the heating measured by the measuring unit 172 when the vibration element 171 vibrates 30 seconds and 310 seconds after the start of heating. The actual change in resistance value of section 121 is shown. The vibration element 171 vibrates 30 seconds and 310 seconds after the start of heating as a notification of the timing at which the puffable period starts and a timing a predetermined time before the end of the puffable period.

As shown in FIG. 4 , the resistance value of the heating unit 121 is slightly fluctuating up and down while maintaining the same ideal trend as shown in FIG. 3 . One reason why the resistance value of the heating unit 121 rises and falls slightly is that the measuring unit 172 samples the resistance value at a predetermined sampling period and the control unit 116 performs power supply control at the sampling period. . However, relatively large fluctuations occur in the timing of power supply to the vibration element 171. This point will be explained in detail with reference to FIGS. 5 and 6.

FIGS. 5 and 6 are enlarged graphs showing the vicinity of the timing at which power is supplied to the vibration element 171 among the graphs shown in FIG. 4 . In Figure 5, the actual transition of the heating unit 121 around 30 seconds from the start of heating is shown. In the example shown in FIG. 5, a fluctuation of 0.02 Ω occurs immediately after the timing at which power is supplied to the vibration element 171. In Figure 6, the actual transition of the heating unit 121 around 310 seconds from the start of heating is shown. In the example shown in FIG. 6, a fluctuation of 0.03 Ω occurs immediately after the timing at which power is supplied to the vibration element 171.

The cause of this relatively large variation is the generation of noise due to power supply to the vibration element 171. When starting to supply power to the vibration element 171, the current load on the power supply unit 111 increases in a stepwise manner. As a transient response of this current load, fluctuations occur in the resistance value measured by the measuring unit 172. In detail, at the moment when the current load increases due to power supply to the vibration element 171, a large fluctuation occurs in the voltage of the power supply unit 111. And, due to momentary fluctuations in voltage, fluctuations (i.e., noise) occur in the resistance value measured by the measuring unit 172. For this reason, immediately after power is supplied to the vibration element 171 sharing the heating unit 121 and the power supply unit 111, noise is generated in the resistance value measured by the measuring unit 172.

Noise generated in the resistance value adversely affects the operation control of the heating unit 121. In that case, it becomes difficult to realize the temperature transition as designed in the heating profile, and the user experience may deteriorate. Additionally, if a function for determining an error based on a resistance value is mounted on the suction device 100, an error may be determined by mistake. In that case, measures such as stopping heating, which are originally unnecessary, are implemented, putting the user at a disadvantage.

Therefore, in this embodiment, by implementing measures against noise occurring in resistance values, the occurrence of such inconveniences is prevented and the quality of user experience is improved.

(5) Noise measures

The control unit 116 performs processing to correct the resistance value measured by the measurement unit 172 (hereinafter also referred to as correction processing) upon the start of power supply from the power supply unit 111 to the vibration element 171. By correcting the resistance value in which noise occurs, it is possible to prevent the occurrence of inconvenience caused by noise in the resistance value and improve the quality of user experience.

The correction process includes setting a period to be corrected according to the start of power supply from the power supply unit 111 to the vibration element 171, and determining that the resistance value measured by the measurement unit 172 in the period to be corrected is included in the range to be corrected. In this case, it includes correcting the corresponding resistance value. The correction target period is a period during which the measured resistance value can be corrected. By limiting the correction target period, it becomes possible to reduce the processing load. The correction target range is the range of resistance values in which noise can be considered to have occurred. By setting the correction target range, it becomes possible to correct the resistance value where noise is considered to have occurred and exclude the influence of noise.

-Setting of compensation target period

The correction target period may be the period from the start of power supply to the vibration element 171 until the resistance value of a predetermined sampling number is measured. As shown in Figures 5 and 6, a large noise is generated immediately after power is supplied to the vibration element 171, and thereafter the variation in resistance value converges. In this regard, according to this configuration, the correction target period can be limited to a period in which large noise may occur due to power supply to the vibration element 171. Therefore, it becomes possible to reduce the processing load.

The correction target period may be the period from when power supply to the vibration element 171 starts until it stops. According to this configuration, all periods in which noise may occur due to power supply to the vibration element 171 can be included in the correction target period. Therefore, it becomes possible to further prevent the occurrence of inconvenience caused by noise occurring in the resistance value.

-Setting of compensation target range

The control unit 116 may set the correction target range according to the previously measured resistance value. For example, the control unit 116 sets the range in which the difference from the resistance value measured at the previous sampling time exceeds a predetermined value at a certain sampling time as the correction target range. That is, when the difference between the resistance value measured at a certain sampling time and the resistance value measured at the sampling time preceding it exceeds a predetermined value, the control unit 116 determines the resistance value measured at a certain sampling time. You can correct it. According to this configuration, the occurrence of noise can be monitored while updating the correction target range according to changes in resistance value. Setting such a correction target range is particularly effective in a period in which the resistance value is assumed to change, that is, in a period in which the target temperature in the heating profile changes (i.e., temperature rise period and temperature fall period).

The control unit 116 may set the correction target range according to the target temperature corresponding to the elapsed time from the start of heating. For example, the control unit 116 sets the range in which the difference from the resistance value corresponding to the target temperature corresponding to the elapsed time from the start of heating exceeds a predetermined value as the correction target range. According to this configuration, the occurrence of noise can be monitored while suppressing the update frequency of the correction target range. Setting such a correction target range is particularly effective in a period during which it is assumed that the resistance value does not change, that is, a period during which the target temperature in the heating profile does not change (i.e., a temperature maintenance period).

Additionally, when the puff is performed, the temperature of the heating unit 121 temporarily decreases. Therefore, the control unit 116 may switch the method of setting the correction target range when a puff is detected. For example, the control unit 116 sets the correction target range according to the previously measured resistance value for a predetermined period after the puff is detected, and sets the target temperature corresponding to the elapsed time from the start of heating for other periods. You can set the correction target range accordingly.

The control unit 116 may select a method for setting the correction target range according to the period in the heating profile corresponding to the elapsed time from the start of heating. According to this configuration, it becomes possible to set the correction target range while switching to an effective setting method for each period specified in the heating profile. This makes it possible to more appropriately exclude the influence of noise.

Specifically, the control unit 116 may set the correction target range according to the target temperature corresponding to the elapsed time from the start of heating during the period in which the target temperature does not change, that is, the temperature maintenance period. According to this configuration, it becomes possible to perform more effective correction during the temperature maintenance period.

On the other hand, the control unit 116 may set the correction target range according to the previously measured resistance value during the period in which the target temperature changes, that is, the temperature increase period and the temperature decrease period. According to this configuration, it becomes possible to perform more effective correction in the temperature rising period and the temperature falling period.

-How to correct resistance value

There are various ways to correct the resistance value of the correction target. Below, an example is explained. In addition, the resistance value to be corrected is a resistance value measured during the period to be corrected and is included in the range to be corrected.

The control unit 116 may correct the resistance value to be corrected to a resistance value measured before the resistance value to be corrected. For example, the control unit 116 corrects the resistance value of the correction target with the previously measured correction value. This correction method is particularly effective in a period in which it is assumed that the resistance value does not change, that is, in a period in which the target temperature in the heating profile does not change (i.e., temperature maintenance period).

The control unit 116 may correct the resistance value to be corrected by linear complementation. Alternatively, the control unit 116 may correct the resistance value to be corrected using a moving average. In either case, the control unit 116 can correct the resistance value to be corrected by following the approximate trend of change in resistance value. This correction method is particularly effective in the period in which the resistance value is assumed to change, that is, in the period in which the target temperature in the heating profile changes (i.e., the temperature increase period and the temperature decrease period).

The control unit 116 may select a method for correcting the resistance value of the correction target in the correction process according to the period in the heating profile corresponding to the elapsed time from the start of heating. According to this configuration, it becomes possible to correct the resistance value of the measurement target while switching to an effective correction method at each period specified in the heating profile. This makes it possible to more appropriately exclude the influence of noise.

Specifically, during a period in which the target temperature does not change, that is, a temperature maintenance period, the control unit 116 may correct the resistance value to be corrected to a resistance value measured before the resistance value to be corrected. According to this configuration, it becomes possible to perform more effective correction during the temperature maintenance period.

On the other hand, the control unit 116 may correct the resistance value to be corrected using linear complementation or moving average during the period in which the target temperature changes, that is, the temperature rising period and the temperature falling period. According to this configuration, it becomes possible to perform more effective correction in the temperature rising period and the temperature falling period.

-Error handling

The control unit 116 determines the number of times that the resistance value measured by the measurement unit 172 is included in the range to be corrected (simply, the number of times the resistance value has been corrected) in the period to be corrected at a first predetermined number of times. When the temperature is reached, heating by the heating unit 121 may be prohibited. Prohibiting heating by the heating unit 121 refers to stopping heating when heating is in progress and not performing heating even if a user operation instructing to start heating is performed in the future. The control unit 116 may prohibit heating by the heating unit 121 when the number of times the resistance value has been corrected in one correction target period reaches a first predetermined number of times. Alternatively, the control unit 116 may operate the heating unit 121 when the total number of times the resistance value has been corrected in a plurality of correction target periods set during heating based on one heating profile reaches the first predetermined number of times. Heating may be prohibited. If the number of corrections is too large, it may be thought that some error has occurred in the heating unit 121 rather than noise. In this regard, according to this configuration, it is possible to determine an error in the heating unit 121 and improve user safety.

In particular, the control unit 116 controls the heating unit 121 when the number of times the resistance value measured by the measurement unit 172 is continuously included in the range to be corrected reaches the first predetermined number of times during the period to be corrected. ) may be prohibited. If the resistance value is continuously included in the correction target range, it can be considered that there is a high probability that some error has occurred in the heating unit 121. According to this point and this configuration, it becomes possible to further increase user safety.

On the other hand, the control unit 116 operates the heating unit ( 121), heating may be prohibited. The error determination range is the range of resistance values within which it can be considered that a malfunction has occurred in the heating unit 121. The error determination range can be set in the same way as the correction target range. According to this configuration, it becomes possible to determine an error in the heating unit 121 even during a period in which power is not supplied to the vibration element 171, thereby improving user safety.

Additionally, the control unit 116 may set the error determination range to be more stringent than the correction target range. In detail, if the correction target range includes a range above the first threshold and a range below the second threshold, the error determination range is a range above the third threshold that is lower than the first threshold. , and a range below the fourth threshold that is higher than the second threshold. That is, the control unit 116 corrects the resistance value if the resistance value measured in the period to be corrected is greater than or equal to the first threshold value, and the control unit 116 corrects the resistance value if the resistance value measured in a period other than the period to be corrected is greater than the first threshold value. If it is greater than the lower third threshold, it is determined that an error has occurred. In addition, the control unit 116 corrects the resistance value if the resistance value measured in the period to be corrected is less than the second threshold value, and the control unit 116 corrects the resistance value if the resistance value measured in the period other than the period to be corrected is less than the second threshold value. If it is less than the fourth high threshold, it is determined that an error has occurred. In the period subject to correction, the resistance value can be considered to fluctuate more significantly due to the influence of noise compared to periods other than the period subject to correction. In this regard, by setting the correction target range looser than the error determination range, it becomes possible to prevent the change in resistance value due to the influence of noise from being misjudged as an error.

Here, the first predetermined number of times is preferably set to be greater than the second predetermined number of times. This is because noise occurring in the resistance value due to power supply to the vibration element 171 is not an error. In this regard, according to this configuration, it is possible to prevent a situation in which the user suffers a disadvantage due to misjudgment of the occurrence of noise as an error.

(6) Processing flow

FIG. 7 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. 7, first, the control unit 116 determines whether a puff request has been detected (step S102). A puff request is a user operation requesting the creation of an aerosol (i.e., instructing the start of heating). An example of a puff request is an operation on the suction device 100, such as operating a switch installed on the suction device 100. Another example of a puff request is to insert a stick-shaped substrate 150 into the suction device 100. In addition, the insertion of the stick-shaped base material 150 into the suction device 100 is performed using a capacitance-type proximity sensor that detects the capacitance of the space near the opening 142, or a pressure sensor that detects the pressure in the internal space 141. It can be detected by a sensor or the like.

When it is determined that a puff request is not detected (step S102: NO), the control unit 116 waits until a puff request is detected.

On the other hand, when it is determined that a puff request has been detected (step S102: YES), the control unit 116 controls the operation of the heating unit 121 to start heating based on the heating profile (step S104). For example, the control unit 116 controls the power supply unit 111 so that the actual temperature of the heating unit 121 corresponding to the resistance value measured by the measuring unit 172 changes to be the same as the target temperature specified in the heating profile. ) starts the process of controlling the power supply from.

Next, the control unit 116 determines whether the error condition is met (step S106). An example of an error condition is that the number of times the resistance value measured by the measuring unit 172 falls within the range to be corrected reaches a first predetermined number of times during the period to be corrected. Another example of an error condition is that the number of times the resistance value measured by the measuring unit 172 falls within the error determination range reaches a second predetermined number of times.

When it is determined that the error condition is met (step S106: YES), the control unit 116 prohibits heating by the heating unit 121 (step S108). After that, processing ends.

When it is determined that the error condition is not met (step S106: NO), the control unit 116 determines whether the end condition is met (step S110). An example of an end condition is that the elapsed time from the start of heating reaches a predetermined time. Another example of an end condition is that the number of puffs from the start of heating has reached a predetermined number.

When it is determined that the termination condition is met (step S110: YES), the control unit 116 ends heating based on the heating profile (step S112). After that, processing ends.

When it is determined that the end condition is not met (step S110: NO), the control unit 116 determines whether to start supplying power to the vibration element 171 (step S114). For example, the control unit 116 determines to start feeding power to the vibration element 171 when the timing at which the puffable period starts and the timing at which the puffable period ends is a predetermined time arrives.

When it is determined that power supply to the vibration element 171 is not to be started (114: NO), the process returns to step S106.

When it is determined to start feeding power to the vibration element 171 (114: YES), the control unit 116 starts feeding power to the vibration element 171 and sets a correction target period (step S116). For example, the control unit 116 sets a predetermined period after power supply to the vibration element 171 starts as the correction target period.

Next, the control unit 116 determines whether the current time is within the correction target period (step S118).

If it is determined that the current time is outside the correction target period, that is, the correction target period has ended (step S118: NO), the process returns to step S106.

When it is determined that the current time is within the correction target period (step S118: YES), the control unit 116 determines whether the resistance value of the heating unit 121 measured by the measurement unit 172 is included in the correction target range. Make a decision (step S120).

When it is determined that the resistance value of the heating unit 121 is not included in the correction target range (step S120: NO), the process returns to step S118.

When it is determined that the resistance value of the heating unit 121 is included in the range to be corrected (step S120: YES), the control unit 116 corrects the resistance value included in the range to be corrected (step S122). For example, the control unit 116 corrects the resistance value to be corrected with the previously measured resistance value, or corrects it using linear complementation or moving average.

Next, the control unit 116 controls heating based on the heating profile based on the corrected resistance value (step S124). After that, the process returns to step S118.

＜3. Second embodiment>

In this embodiment, correction processing for the resistance value of the heating unit 121 is performed by taking into account the temperature drop of the heating unit 121 due to the puff.

The control unit 116 determines that the puff has been performed when the value corresponding to the puff is detected by the sensor unit 112. An example of a value depending on the puff is the temperature drop in the air passage, which is detected by a temperature sensor such as a thermistor disposed in the air passage to the holding portion 140. When a deep puff (a puff with a large amount of suction) is applied, the temperature decreases significantly, and when a shallow puff (a puff with a small amount of suction) is applied, the temperature decreases slightly.

The control unit 116 performs correction processing according to the puff being performed. When the puff is performed, not only the air flow path but also the temperature of the heating unit 121 decreases, so the resistance value of the heating unit 121 changes. In this regard, according to this configuration, it becomes possible to more appropriately exclude the influence of noise by taking into account the change in resistance value due to the influence of the puff.

In detail, the control unit 116 may set the correction target range according to the puff performed. For example, the control unit 116 estimates the amount of decrease in the resistance value of the heating unit 121 due to the puff according to a decrease in the temperature of the air passage. In addition, the control unit 116 may reduce the correction target range set upon the start of power supply to the vibration element 171 by an amount equivalent to the decrease in resistance value due to the puff.

Additionally, the control unit 116 may correct the resistance value to be corrected according to the puff being performed. For example, when correcting the resistance value of the correction target using a moving average, the control unit 116 may apply the moving average limited to the value after the puff is performed.

＜4. Third embodiment>

In this embodiment, when the amount of power supplied from the power source unit 111 to the heating unit 121 changes significantly, the resistance value of the heating unit 121 is corrected by taking this change into account.

The control unit 116 performs correction processing when the amount of change in the amount of power supplied from the power source unit 111 to the heating unit 121 exceeds a predetermined threshold value. When the amount of power supplied to the heating unit 121 changes significantly, the resistance value of the heating unit 121 also changes significantly. In this regard, according to this configuration, it becomes possible to more appropriately exclude the influence of noise by taking into account the change in resistance value resulting from a large change in the amount of power supplied to the heating unit 121.

An example of a factor causing a large change in the amount of power supplied to the heating unit 121 is that a deep puff is applied. When a deep puff is performed, the temperature of the heating unit 121 decreases significantly and the difference from the target temperature increases. Therefore, the duty ratio of the power pulse supplied to the heating unit 121 is controlled to increase. Accordingly, noise may occur in the resistance value of the heating unit 121 measured by the measuring unit 172.

Therefore, the control unit 116 performs correction processing as the amount of change in the amount of power supplied to the heating unit 121 exceeds a predetermined threshold value. This correction process involves setting a period to be corrected when the amount of change in the amount of power supplied from the power source unit 111 to the heating unit 121 exceeds a predetermined threshold, and measuring the period by the measurement unit 172 in the period to be corrected. This includes correcting the resistance value when the calculated resistance value is included in the range to be corrected. Setting of the period to be corrected, setting of the range to be corrected, correction method for the resistance value, and error processing may be performed in the same manner as in the first embodiment. According to this configuration, it becomes possible to appropriately exclude the influence of noise generated due to a large change in the amount of power supplied to the heating unit 121.

The correction target period set in accordance with the start of power supply from the power source unit 111 to the vibration element 171 explained in the first embodiment is also called the first correction target period. On the other hand, the correction target range set according to the amount of change in the amount of power supplied from the power source unit 111 to the heating unit 121 exceeding a predetermined threshold value, explained in this embodiment, is also called the second correction target period. When these first correction target periods and the second correction target periods overlap, the control unit 116 connects the first correction target period and the second correction target period. For example, a case may be considered in which the vibration element 171 vibrates between the time a deep puff is performed and the second period to be corrected starts and the end to the end of the period to be corrected, and the period to be corrected is started. In that case, the control unit 116 performs correction processing using a series of correction target periods from the start of the second correction target period to the end of the first correction target period. According to this configuration, even when a large change in the amount of power supplied to the heating unit 121 and vibration of the vibration element 171 occur simultaneously, it becomes possible to appropriately exclude the influence of noise.

＜5. Supplement>

As mentioned above, preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to these examples. It is clear that a person with ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims, and these are also discussed. , it is understood that it naturally falls within the technical scope of the present invention.

For example, in the above embodiment, an example in which the heating profile is information defining the time series transition of the target temperature has been described, but the present invention is not limited to this example. For example, the heating profile may be information that specifies the time series transition of the target resistance value of the heating unit 121. In that case, the control unit 116 controls the operation of the heating unit 121 so that the measured resistance value changes to be the same as the resistance value specified in the heating profile.

For example, in the above embodiment, an example in which the power supply unit 111 is comprised of a rechargeable battery has been described, but the present invention is not limited to this example. The power supply unit 111 may include a voltage adjustment device such as a step-up/down converter and an LDO (Low Drop Out) regulator in addition to the battery. In that case, the power supply feeding the heating unit 121, the vibration element 171, and the measuring unit 172 may all be the same battery or voltage regulator, or at least some of them may be different. Even if a voltage adjustment device is included, the input value is supplied from the battery, so even if the heating unit 121, the vibration element 171, and the measuring unit 172 receive power from different power sources, there is bias in the voltage. can occur. That is, even if the power supply unit 111 includes a voltage adjustment device and the heating unit 121, the vibration element 171, and the measuring unit 172 receive power from different power sources, they are supplied from the same power supply unit 111. Bias in one voltage occurs. In addition, when power is supplied via the same voltage regulator, compared to the case where power is supplied via a different voltage regulator, the noise in the resistance value measured by the measurement unit 172 due to power supply to the vibration element 171 is It's easy to happen.

For example, in the above embodiment, an example has been described where weak power supply to the heating unit 121 continues even during the intermediate temperature drop period. However, the present invention is not limited to this example. In the mid-temperature lowering period, power supply to the heating unit 121 may be stopped. In that case, the temperature of the heating unit 121 may be separately detected by a temperature sensor such as a thermistor and used to control the heating unit 121. Additionally, with regard to the temperature sensor, it is desirable to implement hardware measures to suppress the generation of noise due to power supply to the vibration element 171. This is because the above-described correction process is not applied to the temperature of the heating unit 121 detected by the temperature sensor. As an example, the temperature sensor, the heating unit 121, and the vibration element 171 may be supplied with power via different voltage regulators. As another example, a condenser may be disposed between the power supply unit 111 and the temperature sensor.

For example, in the third embodiment described above, deep puffs were used as an example of a factor causing a large change in the amount of power supplied to the heating unit 121, but the present invention is not limited to this example. Another factor is that heating by the heating unit 121 is started from a stopped state. For example, when the power supply to the heating unit 121 is stopped in the mid-temperature lowering period and then the power supply to the heating unit 121 is resumed in the re-heating period, the amount of power supplied to the heating unit 121 changes significantly. , noise may occur in the resistance value of the heating unit 121 measured by the measuring unit 172. Therefore, the control unit 116 may perform correction processing by triggering the fact that the amount of change in the amount of power supplied to the heating unit 121 exceeds a predetermined threshold value due to switching from heating off to heating on. The contents of the correction process are as described in the third embodiment. Additionally, when switching from heating off to heating on, the temperature of the heating unit 121 increases significantly. Therefore, when a weak power supply is applied to the heating unit 121 immediately before switching to heating-on to obtain a resistance value and the resistance value to be corrected is corrected, the resistance value obtained just before switching to heating-on is corrected. It is preferable to use it as the resistance value later. Alternatively, it is preferable to use the resistance value measured immediately after switching to heating on, at least before the influence of noise due to transient response reaches its peak, as the resistance value after correction. This is because the resistance value measured immediately after switching to heating on, at least before the effect of noise due to transient response peaks, can be considered to have a smaller effect of noise due to transient response compared to the resistance value measured thereafter. am.

For example, in the above embodiment, an example in which the vibration element 171 vibrates at timings related to the beginning and end of the puffable period has been described, but the present invention is not limited to this example. The vibration element 171 may vibrate at any timing during heating by the heating unit 121.

For example, in the above embodiment, the vibration element 171 is given as an example of an operating unit different from the heating unit 121 that operates using power supplied from the power supply unit 111, but the present invention is not limited to this example. No. The control unit 116 may control the process of correcting the resistance value in accordance with the start of power supply to any operation unit that operates using power supplied from the power supply unit 111. An example of an operating unit is a light-emitting element, which is a device that emits light. In addition, examples of the operating unit include a display device that displays images and a sound output device that outputs sound.

For example, in the above embodiment, an example in which correction processing is controlled according to the start of power supply to the operation unit has been described, but the present invention is not limited to this example. For example, correction processing may be controlled according to the operation contents of the operation unit executed by power supply to the operation unit. Specifically, the control unit 116 may set the length of the correction target period or select a correction method for the resistance value according to the vibration pattern (amplitude, vibration interval, etc.) of the vibration element 171. The current load on the power supply unit 111 may vary depending on the vibration pattern. By this point and this configuration, it becomes possible to more appropriately exclude the influence of noise.

For example, in the above embodiment, an example has been described where the measured value measured by the measurement unit 172 is the resistance value of the heating unit 121, but the present invention is not limited to this example. The measured value measured by the measuring unit 172 may be the temperature of the heating unit 121. The measured value measured by the measuring unit 172 may be the voltage drop in the heating unit 121.

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. The programs constituting the software are stored in advance in a recording medium (specifically, a non-transitory storage medium readable by a computer) installed inside or outside each device. And, for example, each program is read into RAM when executed by a computer that controls each device described in this specification, and is executed by a processor such as CPU. The recording medium is, for example, a magnetic disk, optical disk, optical magnetic disk, flash memory, etc. Additionally, the above computer program may be delivered, for example, through a network, without using a recording medium.

In addition, the processes explained using flow charts and sequence diagrams in this specification do not necessarily have to be executed in the order shown. Several processing steps may be executed in parallel. Additionally, additional processing steps may be employed, or some processing steps may be omitted.

In addition, the following configuration also falls within the technical scope of the present invention.

A power supply unit that supplies power,

a heating unit that heats a substrate containing an aerosol source using power supplied from the power supply unit;
