[Outline of Embodiment]
The non-burning type flavor inhaler described in the background art described above starts supplying power output to the atomizing unit in response to detection of the puff operation. However, since the temperature of the atomizing portion changes during the generation of the aerosol by the atomizing portion, the particle size distribution of the particles constituting the aerosol is widened. In other words, the particle size of the particles constituting the aerosol varies within one puff operation or between a plurality of puff operations.

The non-combustion type flavor inhaler according to the embodiment includes an atomization unit that atomizes an aerosol source without combustion, and a control unit that controls a power output to the atomization unit. The supply of power output to the atomizing unit is started before the start of the puffing operation, and the supply of power output to the atomizing unit is stopped during the user's puffing operation.

In the embodiment, the flavor source 132 is constituted by a raw material piece that imparts a flavor component to the aerosol generated from the atomization unit 111. The size of the raw material piece is 0.2 mm or more.
It is preferable that it is 2 mm or less. Furthermore, the size of the raw material pieces is 0.2 mm or more and 0.7.
It is preferable that it is mm or less. The smaller the size of the raw material pieces constituting the flavor source 132,
Since the specific surface area increases, the flavor component is easily released from the raw material pieces constituting the flavor source 132. Therefore, the amount of the raw material pieces can be suppressed when applying the desired amount of flavor component to the aerosol. As a raw material piece which comprises the flavor source 132, the molded object which shape | molded the cut tobacco and the tobacco raw material in the granule can be used. However, the flavor source 132 may be a molded body obtained by molding a tobacco material into a sheet shape. Moreover, the raw material piece which comprises the flavor source 132 may be comprised by plants (for example, mint, an herb, etc.) other than tobacco. The flavor source 132 may be provided with a fragrance such as menthol.

Here, the raw material piece which comprises the flavor source 132 is obtained by sieving based on JIS Z 8815 using, for example, a stainless steel screen based on JIS Z 8801. For example, using a stainless steel sieve having an opening of 0.71 mm, the raw material pieces are screened for 20 minutes by a dry and mechanical shaking method, and then passed through a stainless steel sieve having an opening of 0.71 mm. Get raw material pieces. Subsequently, using a stainless steel sieve having an opening of 0.212 mm, the raw material pieces are sieved for 20 minutes by a dry and mechanical shaking method, and then passed through a stainless steel sieve having an opening of 0.212 mm. Remove raw material pieces. That is, the raw material piece constituting the flavor source 132 is a stainless steel sieve that defines an upper limit (mesh opening = 0.71 m).
It is a raw material piece that passes through m) and does not pass through a stainless steel sieve (mesh opening = 0.212 mm) that defines the lower limit. Therefore, in the embodiment, the lower limit of the size of the raw material pieces constituting the flavor source 132 is
It is defined by the opening of the stainless steel sieve that defines the lower limit. In addition, the upper limit of the size of the raw material piece which comprises the flavor source 132 is defined by the opening of the stainless steel sieve which prescribes | regulates an upper limit.

In an embodiment, the flavor source 132 is a tobacco source having an alkaline pH. The pH of the tobacco source is preferably greater than 7, more preferably 8 or more. pH
By making the value larger than 7, the flavor component generated from the tobacco source can be efficiently taken out by the aerosol. Thereby, in providing a desired amount of flavor components to the aerosol, the amount of tobacco source can be suppressed. On the other hand, the pH of the tobacco source is preferably 12 or less, and more preferably 10 or less. By setting the pH to 12 or less, damage (corrosion or the like) to the flavor suction device 100 (for example, the cartridge 130 or the suction device body 110) can be more effectively suppressed.

It should be noted that the flavor component generated from the flavor source 132 is conveyed by aerosol, and it is not necessary to heat the flavor source 132 itself.

The mesh 133A is provided so as to close the opening of the cartridge housing 131 upstream of the flavor source 132, and the filter 133B is provided so as to close the opening of the cartridge housing 131 downstream of the flavor source 132. The mesh 133A is a flavor source 13

It has an opening of 0.077 mm or more and 0.198 mm or less. The filter 133B is made of a material having air permeability. The filter 133B is preferably an acetate filter, for example. The filter 133B has such a roughness that the raw material pieces constituting the flavor source 132 do not pass through.

(Block configuration)
Hereinafter, a block configuration of the non-burning type flavor inhaler according to the embodiment will be described.
FIG. 3 is a diagram illustrating a block configuration of the flavor inhaler 100 according to the embodiment.

As shown in FIG. 3, the control circuit 50 includes a power switch 51, an atomization switch 52, and a control unit 53.

The power switch 51 is turned on when the flavor inhaler 100 is turned on, and is turned off when the flavor inhaler 100 is turned off. For example, the power switch 51 is connected to the push button 30 and is turned on when the push button 30 is continuously pushed a predetermined number of times in a state where the flavor inhaler 100 is not turned on. It may be switched. On the other hand, the power switch 51 may be switched to an off state when the push button 30 is continuously pressed a predetermined number of times in a state where the flavor inhaler 100 is turned on. Alternatively, the power switch 51 may have a timer that starts in response to the end of the puff operation, and may be switched to an off state in response to the expiration of the timer (elapse of a predetermined time).

When the user's puffing operation is performed, the atomization switch 52 switches to a state (off state) in which the supply of power output to the atomizing unit 111R is stopped, and when the user's puffing operation is not performed, the atomizing unit 52 The state is switched to a state (on state) where supply of power output to 111R is started. In the embodiment, the atomization switch 52 is interlocked with a suction sensor that detects a puff operation. The atomization switch 52 is switched to an off state when a puff operation is detected by the suction sensor 20. On the other hand, the atomization switch 52 is switched to the ON state when the puff operation is no longer detected by the suction sensor 20.

Here, a state in which the puffing operation is not detected by the suction sensor 20 may be referred to as a non-suctioning state, and a state in which the puffing operation is detected by the suction sensor 20 may be referred to as a suctioning state. Therefore, the atomization switch 52 is switched to the off state by switching from the non-suction state to the suction state, and is switched to the on state by switching from the suction state to the non-suction state.

In the state where the power of the flavor inhaler 100 is turned on, the control unit 53 performs the flavor inhaler 100.
To control.

1stly, the control part 53 controls the power supply output with respect to the atomization part 111R. In the embodiment, the control unit 53 starts supplying power output to the atomizing unit 111R before starting the user's puffing operation, and stops supplying power output to the atomizing unit 111R during the user's puffing operation. In the embodiment, when the atomization switch 52 is turned off, the control unit 53 stops the supply of power output to the atomization unit 111R. On the other hand, the control part 53 starts supply of the power output with respect to the atomization part 111R, when the atomization switch 52 will be in an ON state. In other words, the control unit 53 stops the supply of the power output to the atomizing unit 111R when the puff operation is detected by the suction sensor 20. On the other hand, the control unit 53 includes the suction sensor 20.
When the puff motion is no longer detected, supply of power output to the atomizing unit 111R is started.

Here, the magnitude of the power output is defined by the value of the voltage applied to the atomizing unit 111R in the case where a voltage is continuously applied to the atomizing unit 111R. On the other hand, in the case where the voltage is intermittently applied to the atomizing unit 111R (pulse control), the magnitude of the power output is the value of the voltage applied to the atomizing unit 111R, the pulse width, and the like. It is defined by at least one parameter of the pulse interval.

In the embodiment, the control unit 53 may stop supplying the power output to the atomizing unit 111R when the first time has elapsed since the supply of the power output to the atomizing unit 111R is started. Here, the first time is a time for keeping the supply amount of the aerosol within a desired amount without depending on the time length of the non-suction state. In other words, the first time is a time set in order to prevent the supply amount of the aerosol from exceeding the upper limit of the range of the desired amount.

For example, the upper limit of the first time is preferably 5 seconds. More preferably, the upper limit of the first time is 4 seconds, and even more preferably, the upper limit of the first time is 3 seconds. For example, the lower limit of the first time is preferably 0.5 seconds. More preferably, the lower limit of the first time is 1 second, and even more preferably, the lower limit of the first time is 1.5 seconds. For example, the first time is 0.
It is preferably 5 seconds or more and 5 seconds or less. More preferably, the first time is preferably not less than 1 second and not more than 4 seconds. Even more preferably, the first time is 1.5 seconds or more and 3 seconds or less.

In the embodiment, the control unit 53 resumes the supply of the power output to the atomizing unit 111R when the second time has elapsed since the supply of the power output to the atomizing unit 111R is stopped by the lapse of the first time. May be. Here, the second time is a time determined in order to prevent the supply amount of the aerosol from falling below the lower limit of the desired amount range due to the condensation of the aerosol on the wall surface exposed to the aerosol flow path. The condensed aerosol absorbed by the absorbing member 111S may be re-atomized by restarting the supply of power output.

As described above, when the absorbing member 111S is not in contact with the reservoir 111P, the aerosol absorbed by the absorbing member 111S (condensed aerosol) is transferred from the absorbing member 111S to the atomizing portion 111R using the capillary phenomenon. Preferably, it is guided. On the other hand, when the absorbing member 111S is in contact with the reservoir 111P, the aerosol absorbed by the absorbing member 111S (condensed aerosol) is transferred from the absorbing member 111S to the reservoir 111P.
It is preferable to be guided to.

Secondly, the control unit 53 controls the light emitting element 40. In the embodiment, the control unit 53
The light emitting element 40 may be controlled so as to notify that a desired amount of aerosol can be supplied. The control unit 53 may control the light emitting element 40 so as to continuously notify that the desired amount of aerosol can be supplied from the start to the end of the period in which the desired amount of aerosol can be supplied. Good. For example, the start timing of the period during which a desired amount of aerosol can be supplied is the atomization unit 111R.
This is a timing at which a fixed time shorter than the first time elapses after the supply of the power supply output to is started. The certain time is, for example, the time from the start of supplying the power output to the atomizing unit 111R until the aerosol supply amount reaches the lower limit of the desired amount range.

In addition, the control unit 53 may control the light emitting element 40 so as to notify that the desired amount of aerosol cannot be supplied. The control unit 53 controls the light emitting element 40 so as to continuously notify that the desired amount of aerosol cannot be supplied from the start to the end of the period in which the desired amount of aerosol cannot be supplied. Good. The start timing of the period during which the desired amount of aerosol cannot be supplied is, for example, the timing when the supply of the power output to the atomizing unit 111R is started. Note that the end timing of the period during which the desired amount of aerosol cannot be supplied is the same as the start timing of the period during which the desired amount of aerosol can be supplied.

Thirdly, the control unit 53 may trigger the energization process for the atomizing unit 111R when switching from the non-suction state to the suction state and switching from the suction state to the non-suction state are performed. In other words, the first puffing operation is performed to trigger the energization process for the atomizing unit 111R without generating aerosol. The energization process for the atomizing unit 111R is a process for generating aerosol by supplying power output to the atomizing unit 111R.

For example, the first puff operation may be used to authenticate whether or not the user is a regular user. For example, when the response value of the suction sensor 20 associated with the first puff operation satisfies a predetermined condition (for example, a condition where the gradient of the flow velocity is equal to or greater than a predetermined value), the user is authenticated as a regular user. The first puff operation may be the first puff operation after the power source of the flavor inhaler 100 is introduced, and is the first puff operation after a predetermined time has elapsed without performing the puff operation. Also good. Here, for the first puff operation, the control unit 53 performs the energization process for the atomization unit 111R if switching from the non-suction state to the suction state and switching from the suction state to the non-suction state are not performed within the trigger time. Does not have to be triggered. For such an authentication operation, the entire contents of International Application No. PCT / JP2015 / 63036 (filed on April 30, 2015) are incorporated by reference.

(Control example)
Below, the example of control of the power supply output with respect to the atomization part 111R which concerns on embodiment is demonstrated. FIG. 4 is a diagram for explaining a control example of power output to the atomization unit 111R according to the embodiment.

As described above, the control unit 53 starts supplying power output to the atomization unit 111R when the atomization switch 52 is turned on (that is, the non-suction state). The control unit 53
When the atomization switch 52 is turned off (that is, the suction state), supply of power output to the atomization unit 111R is stopped.

In such a case, as shown in FIG. 4, the control unit 53 starts supplying power output to the atomizing unit 111 </ b> R and then maintains the atomization switch 52 in the on state (that is, the non-suction state). When one hour has passed, the supply of power output to the atomization unit 111R is stopped. The first time is a time determined in order to prevent the supply amount of the aerosol from exceeding the upper limit of the range of the desired amount. Note that the first time is variable depending on the amount of aerosol retained in the aerosol flow path.

Further, the control unit 53 stops supplying the power output to the atomizing unit 111R with the passage of the first time, and then the second time has elapsed with the atomization switch 52 being in the on state (that is, the non-suction state). In this case, the supply of power output to the atomizing unit 111R is resumed. The second time is a time determined in order to prevent the aerosol supply amount from falling below the lower limit of the desired amount range. In the control example according to the embodiment, the supply amount of the aerosol is increased or decreased within the range of the desired amount by repeatedly stopping and restarting the supply of the power output to the atomizing unit 111R. here,
The range of the desired amount may be determined by an upper limit and a lower limit, and the lower limit is preferably 0.1 mg or more, and more preferably 1.0 mg or more. On the other hand, the upper limit of the desired amount is 1
It is preferably 0.0 mg or less, and more preferably 5.0 mg or less. 0
. It may be 1 mg or more and 10.0 mg or less, and may be 1.0 mg or more and 5.0 mg or less. Further, the range of the desired amount may be determined based on the target value of the desired amount, for example, a range of ± 50% or less with respect to the target value of the desired amount (for example, the target value of the desired amount is 2.0 mg) The range of the desired amount is preferably 1.0 mg or more and 3.0 mg or less), ± 2
More preferably, it is in the range of 5% or less (for example, when the target value of the desired amount is 2.0 mg, the range of the desired amount is 1.5 mg or more and 2.5 mg or less).

Here, the control unit 53 controls the light emitting element 40 so as to notify that a desired amount of aerosol can be supplied. Further, the control unit 53 controls the light emitting element 40 so as to notify that the desired amount of aerosol cannot be supplied. In the control example according to the embodiment, until the supply amount of the aerosol reaches the lower limit of the desired amount range after starting the supply of the power output to the atomization unit 111R,
It is notified that the desired amount of aerosol cannot be supplied. When the supply amount of the aerosol exceeds the lower limit of the range of the desired amount after the supply of the power output to the atomizing unit 111R is started, it is notified that the desired amount of aerosol can be supplied. The start timing of the period during which a desired amount of aerosol can be supplied is the timing at which a certain time shorter than the first time elapses after the supply of power output to the atomization unit 111R is started. The certain time is, for example, the time from the start of supplying the power output to the atomizing unit 111R until the aerosol supply amount reaches the lower limit of the desired amount range.

(Aerosol delivery method)
Hereinafter, the aerosol delivery method according to the embodiment will be described. 5-7,
It is a flowchart which shows the aerosol delivery method which concerns on embodiment. 5-7, operation | movement of the flavor suction device 100 (control part 53) is mainly demonstrated.

As shown in FIG. 5, in step S10, the flavor inhaler 100 is turned on.
For example, when the push button 30 is continuously pushed in a predetermined number of times, the flavor inhaler 1
00 is turned on.

In step S <b> 20, the control unit 53 controls the power output associated with the puffing operation. Details of step S20 will be described later (see FIGS. 6 and 7).

In step S30, the flavor inhaler 100 is turned off. For example, when the push button 30 is continuously pressed in a predetermined number of times, the flavor suction device 100 is turned off. Alternatively, the power of the flavor inhaler 100 may be turned off when a predetermined time elapses after the puff operation is performed without performing the puff operation.

Next, details of step S20 described above will be described. FIG. 6 is a flowchart showing an aerosol delivery method in the first puff operation. As shown in FIG.
The flavor suction device 100 is in a non-suction state in which the puff operation is not detected by the suction sensor 20.

In step S202, the control unit 53 determines whether switching from the non-suction state to the suction state has been performed. In other words, the control unit 53 determines whether the atomization switch 52 has been switched from the on state to the off state. When the determination result is YES, the control unit 53
The process proceeds to step S203. When the determination result is NO, the control unit 53 returns to the process of step S201.

In step S203, the control unit 53 determines whether switching from the suction state to the non-suction state has been performed. In other words, the control unit 53 determines whether the atomization switch 52 has been switched from the off state to the on state. When the determination result is YES, the control unit 53
The process proceeds to step S204. When the determination result is NO, the control unit 53 waits as it is.

In step S204, the control unit 53 determines whether switching from the non-suction state to the suction state and switching from the suction state to the non-suction state are performed within the trigger time. That is, the control unit 53 determines whether the time from the timing when the switching to the suction state is performed to the timing when the switching to the non-suction state is performed is within the trigger time. Control unit 53
If the determination result is YES, the process proceeds to step S205. The control unit 53
If the determination result is NO, the process returns to step S201. However, step S20
The process of 4 may be omitted.

In step S205, the control part 53 triggers the energization process with respect to the atomization part 111R. That is, the control unit 53 starts supplying power output to the atomizing unit 111R after the first puff operation detected in step S202 and step S203 is performed. The first puff operation may be used to authenticate whether or not the user is a regular user. The first puff operation may be the first puff operation after the flavor inhaler 100 is turned on, and is the first puff operation after a predetermined time has elapsed without performing the puff operation. Also good. The predetermined time is longer than at least the first time and the second time.

Here, the control unit 53 notifies that the desired amount of aerosol cannot be supplied until the supply amount of the aerosol reaches the lower limit of the desired amount range after the supply of power output to the atomizing unit 111R is started. In addition, the light emitting element 40 may be controlled. On the other hand, the control part 53 is the atomization part 1
When the supply amount of the aerosol generated by 11R exceeds the lower limit of the desired amount range, the light emitting element 40 may be controlled so as to notify that the desired amount of aerosol can be supplied. The light emitting element 40 may continuously notify that the desired amount of aerosol can be supplied from the start to the end of the period in which the desired amount of aerosol can be supplied.

In addition, the control part 53 moves to the process of step S211 shown in FIG. 7 after the process of step S205. FIG. 7 is a flowchart showing an aerosol delivery method in a puff operation after authentication (for example, the second and subsequent puff operations).

As shown in FIG. 7, in step S211, the control unit 53 determines whether switching from the non-suction state to the suction state has been performed. In other words, the control unit 53 uses the atomization switch 5
It is determined whether 2 is switched from the on state to the off state. The control unit 53 determines that the determination result is YE
If it is S, the process proceeds to step S212. When the determination result is NO, the control unit 53 proceeds to the process of step S216.

In step S212, the flavor inhaler 100 is in the suction state in which the puffing operation is detected by the suction sensor 20.

In step S213, the control unit 53 stops supplying power output to the atomizing unit 111R.

In step S214, it is determined whether switching from the suction state to the non-suction state has been performed. In other words, the control unit 53 determines whether the atomization switch 52 has been switched from the off state to the on state. When the determination result is YES, the control unit 53 performs step S21.
The process proceeds to 5. When the determination result is NO, the control unit 53 waits until the suction state ends.

In step S215, the control unit 53 resumes the supply of power output to the atomization unit 111R. Here, the control unit 53 notifies the light emitting element 40 that the desired amount of aerosol cannot be supplied until the supply amount of the aerosol generated by the atomizing unit 111R exceeds the lower limit of the desired amount range. You may control. The control unit 53 controls the light emitting element 40 to notify that the desired amount of aerosol can be supplied when the supply amount of the aerosol generated by the atomizing unit 111R exceeds the lower limit of the desired amount range. May be. In addition, the control part 53 is step S2.
After 15, the process returns to step S211.

In step S216, the control unit 53 determines whether the first time has elapsed since the start of the supply of the power output to the atomizing unit 111R. As described above, the first time is a time determined so that the supply amount of the aerosol does not exceed the upper limit of the range of the desired amount. If the determination result is YES, the control unit 53 proceeds to the process of step S217.
When the determination result is NO, the control unit 53 returns to the process of step S211.

In step S217, the control unit 53 stops supplying power output to the atomizing unit 111R. Here, when the supply amount of the aerosol generated by the atomization unit 111R falls below the lower limit of the range of the desired amount, the control unit 53 notifies the light emitting element 40 that the desired amount of aerosol cannot be supplied. May be controlled. The light emitting element 40 may continuously notify that the desired amount of aerosol cannot be supplied from the start to the end of the period in which the desired amount of aerosol cannot be supplied.

However, as in the control example shown in FIG. 4, when the aerosol supply amount increases or decreases within the desired range after the aerosol supply amount exceeds the lower limit of the desired amount range, the aerosol supply amount is the desired amount. Note that the condition above the lower limit of the range is maintained. Therefore, it is not necessary to notify that the desired amount of aerosol cannot be supplied in step S217.

In step S218, the control unit 53 determines whether or not the second time has elapsed since the supply of power output to the atomizing unit 111R was stopped as the first time passed. As described above, the second time is a time determined so that the supply amount of the aerosol does not fall below the lower limit of the desired amount range. If the determination result is YES, the control unit 53 proceeds to the process of step S219. When the determination result is NO, the control unit 53 performs step S2.
The process proceeds to 20.

In step S219, the control unit 53 determines whether an end condition is satisfied.
When the determination result is YES, the control unit 53 ends the series of processes. When the determination result is NO, the control unit 53 returns to the process of step S221. The end condition may be that a predetermined time elapses without performing the puffing operation, or may be that a predetermined number of puffing operations have been performed.

In step S220, the control unit 53 determines whether switching from the non-suction state to the suction state has been performed. In other words, the control unit 53 determines whether the atomization switch 52 has been switched from the on state to the off state. When the determination result is YES, the control unit 53
The process proceeds to step S212. When the determination result is NO, the control unit 53 returns to the process of step S218.

In step S221, the control unit 53 resumes the supply of power output to the atomization unit 111R. Here, as in step S205, the control unit 53 notifies that the aerosol of the desired amount can be supplied when the supply amount of the aerosol generated by the atomizing unit 111R exceeds the lower limit of the range of the desired amount. Thus, the light emitting element 40 may be controlled. The light emitting element 40 may continuously notify that the desired amount of aerosol can be supplied from the start to the end of the period in which the desired amount of aerosol can be supplied.

However, as in the control example shown in FIG. 4, when the aerosol supply amount increases or decreases within the desired range after the aerosol supply amount exceeds the lower limit of the desired amount range, the aerosol supply amount is the desired amount. Note that the condition above the lower limit of the range is maintained. Therefore, when it is notified only once that the supply amount of the aerosol generated by the atomization unit 111R exceeds the lower limit of the range of the desired amount, it is possible to supply the desired amount of aerosol.
It is not necessary to notify that it is possible to supply a desired amount of aerosol at 5. In addition, the control part 53 returns to the process of step S211 after step S221.

As described above, the aerosol delivery method includes various steps, but embodiments are not limited thereto. In the aerosol delivery method, step A (that is, step S205, step S215, step S221) for generating an aerosol in the suction route, and the generation of the aerosol after step A are stopped, and the fluid flows in the suction route. Step B (i.e., Step S213) to be moved into the user's mouth can be included at least.

(Function and effect)
In the embodiment, the control unit 53 stops the supply of power output to the atomization unit 111R during the user's puffing operation. While the aerosol is generated by the atomizing unit 111R, the temperature of the atomizing unit 111R does not change due to the user's puffing operation. Therefore, the situation in which the particle diameter of the particles constituting the aerosol varies during one puff operation or between a plurality of puff operations is suppressed.

In the embodiment, the control unit 53 stops the supply of the power output to the atomization unit 111R when the first time has elapsed since the start of the supply of the power output to the atomization unit 111R. Therefore, the supply amount of the aerosol can be kept within a desired amount without depending on the interval of the puff operation.

In the embodiment, the control unit 53 resumes the supply of the power output to the atomization unit 111R when the second time has elapsed since the supply of the power output to the atomization unit 111R is stopped by the lapse of the first time. . Accordingly, it is possible to suppress the supply amount of the aerosol from falling below the lower limit of the desired amount range due to the condensation of the aerosol on the wall surface exposed to the aerosol flow path.

In the embodiment, the light emitting element 40 notifies that a desired amount of aerosol can be supplied in a period in which the desired amount of aerosol can be supplied. Accordingly, the user can promote the start of the puff operation at an appropriate timing.

In the embodiment, the light emitting element 40 notifies that the desired amount of aerosol cannot be supplied in a period in which the desired amount of aerosol cannot be supplied. Thereby, the start of the puffing operation at an inappropriate timing can be suppressed.

In the embodiment, the absorbing member 111S that absorbs the condensed aerosol is provided on the wall surface exposed to the flow path of the aerosol generated by the atomizing unit 111R. Thereby, waste of the aerosol source can be suppressed by re-atomization of the aerosol absorbed by the absorbing member 111S.

In the embodiment, the control unit 53 triggers the energization process for the atomizing unit 111R when switching from the non-suction state to the suction state and switching from the suction state to the non-suction state are performed. Thereby, the energization process with respect to the atomization part 111R can be triggered appropriately.
Furthermore, the first puff operation can be used for user authentication.

[Modification 1]
Hereinafter, Modification Example 1 of the embodiment will be described. In the following, differences from the embodiment will be mainly described.

Specifically, in the embodiment, the atomization switch 52 is interlocked with the suction sensor 20. In contrast, in the first modification, the atomization switch 52 is connected to the operation interface 80 as shown in FIG.
The operation interface 80 may be the push button 30 described above, or may be an interface provided separately from the push button 30 described above.

The operation interface 80 is an interface configured to be operated before the start of the puff operation. That is, the user operates the operation interface 80 during a period when the puff operation is not performed, and does not operate the operation interface 80 during a period when the puff operation is performed. Therefore, the atomization switch 52 is switched to the off state when the user operation on the operation interface 80 is no longer performed. On the other hand, the atomization switch 52 is provided with the operation interface 8.
When a user operation for 0 is performed, the switch is turned on. That is, a state where a user operation is performed on the operation interface 80 is a non-suction state, and a state where a user operation is not performed on the operation interface 80 is a suction state.

In the first modification, the control unit 53 starts supplying the power output to the atomizing unit 111R when a user operation is performed on the operation interface 80, and the fog is generated when the user operation is not performed on the operation interface 80. The supply of power output to the conversion unit 111R is stopped.

Here, in the case where the control of the embodiment is applied to the first modification example, “when a puff operation is detected by the suction sensor 20” is read as “when no user operation is performed on the operation interface 80”, and “When puff movement is no longer detected by the suction sensor 20” “when a user operation on the operation interface 80 is performed”
Should be read as

In the first modification, assuming such replacement, Step A (Step S205, Step 213, Step 219 described above) is generated in the suction path.
) Is a step of starting supply of power output to the atomization unit 111R when a user operation is performed on the operation interface 80, and in a state where generation of the aerosol is stopped after step A, the aerosol is absorbed in the suction path. The step B of moving into the oral cavity of the user by the fluid flow is a step of stopping the supply of the power output to the atomizing unit 111R when the user operation on the operation interface 80 is not performed.

(Control example)
Hereinafter, a control example of the power output for the atomization unit 111R according to the modification example 1 will be described. FIG. 9 is a diagram for explaining a control example of power output for the atomization unit 111R according to the first modification.

As described above, the control unit 53 starts supplying power output to the atomization unit 111R when a user operation is performed on the operation interface 80. The control unit 53 stops the supply of power output to the atomization unit 111R when the user operation on the operation interface 80 is not performed.

In such a case, as shown in FIG. 9, the control unit 53 starts supplying power output to the atomization unit 111R and then the atomization switch 52 remains in the on state (that is, the non-suction state). When one hour has passed, the supply of power output to the atomization unit 111R is stopped. That is, the supply of power output to the atomization unit 111R is stopped even when the user operation on the operation interface 80 continues. The first time is a time determined in order to prevent the supply amount of the aerosol from exceeding the upper limit of the range of the desired amount. However,
In the control example according to the modification example 1, the control for maintaining the supply amount of the aerosol so as to exceed the lower limit of the range of the desired amount using the second time described above is not performed.

Here, the control unit 53 controls the light emitting element 40 so as to notify that a desired amount of aerosol can be supplied. Further, the control unit 53 controls the light emitting element 40 so as to notify that the desired amount of aerosol cannot be supplied. In the control example according to the modification example 1, when the supply amount of the aerosol is below the lower limit of the desired amount range, it is notified that the desired amount of aerosol cannot be supplied. When the supply amount of the aerosol exceeds the lower limit of the desired amount range, it is notified that the desired amount of aerosol can be supplied.

(Function and effect)
In the first modification, even if the operation interface 80 is used instead of the suction sensor 20, the same effect as that of the embodiment can be obtained. In addition, since the control for maintaining the supply amount of the aerosol so as to exceed the lower limit of the desired amount range using the second time described above is omitted, the power consumption and the processing load are reduced as compared with the embodiment. .

[Modification 2]
Hereinafter, a second modification of the embodiment will be described. In the following, differences from the embodiment will be mainly described.

In the embodiment, an atomization switch 52 that is linked to the suction sensor 20 is provided. On the other hand, in the second modification, as shown in FIG. 10, a first switch 57 linked to the operation interface 80 and a second switch 58 linked to the suction sensor 20 are provided. The operation interface 80 may be the push button 30 described above, and the push button 3 described above.
An interface provided separately from 0 may be used.

In the second modification, the first switch 57 is switched to an on state when a user operation is performed on the operation interface 80, and is switched to an off state when no user operation is performed on the operation interface 80. On the other hand, the second switch 58 switches to the on state when the puff operation is detected by the suction sensor 20, and switches to the off state when the puff operation is no longer detected by the suction sensor 20. That is, the second switch 58 is turned on when the user's puffing operation is started, and is turned off when the user's puffing operation is finished.

In the second modification, the control unit 53 starts supplying power output to the atomizing unit 111R when the first switch 57 is switched to the on state, and when the second switch 58 is switched to the on state. Supply of power output to the atomizing unit 111R is stopped. In other words, the control unit 53 starts supplying power output to the atomizing unit 111R when a user operation is performed on the operation interface 80, and is in a state where the user operation is performed on the operation interface 80. When the puffing operation is detected by the suction sensor 20, the supply of power output to the atomizing unit 111R is stopped.

Thus, in the second modification, the trigger for starting the supply of the power output to the atomizing unit 111R is that the user operation is performed on the operation interface 80 (the first switch 57 is switched to the on state), and the suction is performed. It should be noted that the puffing is not detected by the sensor 20 (the second switch 58 is switched off).

In the second modification, the operation interface 80 is used as an interface for starting supply of power output to the atomizing unit 111R. Therefore, when the user operation on the operation interface 80 is no longer performed, the control unit 53 performs the atomization unit 111.
The supply of power output to R may not be stopped. However, the modified example 2 is not limited to this. Specifically, the control unit 53 may stop supplying the power output to the atomization unit 111R when the user operation on the operation interface 80 is not performed. Specifically, a user operation on the operation interface 80 is performed (that is, the first operation
Under the premise that the switch 57 is on), it may be considered that supply of power output to the atomizing unit 111R is allowed.

In the second modification, it should be noted that, as in the first modification, the control illustrated in FIG. 9 is performed as the power output control for the atomizing unit 111R. That is, the control for maintaining the supply amount of the aerosol so as to exceed the lower limit of the desired amount range using the second time described above is not performed.

In the second modification, from the viewpoint of stopping the supply of power output to the atomizing unit 111R, the second switch 58 that is linked to the suction sensor 20 may be considered as an atomizing switch. From the viewpoint of starting supply of power output to the atomization unit 111R, the first switch 57 that is linked to the operation interface 80 may be considered as an atomization switch.

(Aerosol delivery method)
Hereinafter, the aerosol delivery method according to the modified example 2 will be described. FIG. 11 is a flowchart showing an aerosol delivery method according to the second modification. In FIG. 11, the flavor suction device 100 (
The operation of the control unit 53) will be mainly described. In FIG. 11, step S20 shown in FIG.
Details will be described.

As shown in FIG. 11, in step S311, the first switch 57 is off. That is, no user operation is performed on the operation interface 80.

In step S312, the control unit 53 determines whether an end condition is satisfied.
When the determination result is YES, the control unit 53 ends the series of processes. When the determination result is NO, the control unit 53 returns to the process of step S313. The end condition may be that a predetermined time elapses without performing the puffing operation, or may be that a predetermined number of puffing operations have been performed.

In step S313, the control unit 53 determines whether the first switch 57 has been switched from the off state to the on state. In other words, the control unit 53 determines whether a user operation on the operation interface 80 has been performed. When the determination result is YES, the control unit 53 proceeds to the process of step S314. When the determination result is NO, the control unit 53
The process returns to step S311.

In step S314, the control unit 53 starts supplying power output to the atomizing unit 111R. Here, when the supply amount of the aerosol generated by the atomization unit 111R exceeds the lower limit of the desired amount range, the control unit 53 notifies the light emitting element 40 that the desired amount of aerosol can be supplied. May be controlled.

In step S315, the control unit 53 determines whether the second switch 58 has been switched from the off state to the on state. In other words, the control unit 53 detects whether the puff operation is detected by the suction sensor 20. If the determination result is YES, the control unit 53 proceeds to the process of step S316. If the determination result is NO, the control unit 53 returns to the process of step S318.

In step S316, the control unit 53 stops supplying power output to the atomizing unit 111R.

In step S317, the control unit 53 determines whether the second switch 58 has been switched from the on state to the off state. In other words, the control unit 53 detects whether the puff operation is no longer detected by the suction sensor 20. When the determination result is YES, the control unit 53 returns to the process of step S311. In the flow shown in FIG. 11, when returning to the process of step S <b> 311, the first switch 57 is switched from the on state to the off state even if the user operation on the operation interface 80 is continued. On the other hand, the control unit 53 determines that the determination result is NO.
If it is, it waits as it is. In other words, when the second switch 58 is in the on state due to the detection of the user's puffing operation, the next step is not processed, so even if the first switch 57 is turned on by the user operation on the operation interface 80, It should be noted that power output to the atomization unit 111R does not start.

In step S318, it is determined whether the first switch 57 has been switched from the on state to the off state. In other words, the control unit 53 determines whether a user operation on the operation interface 80 is no longer performed. When the determination result is YES, the control unit 53
The process proceeds to step S319. When the determination result is NO, the control unit 53 returns to the process of step S320.

In step S319, the control unit 53 stops supplying power output to the atomizing unit 111R. Here, when the supply amount of the aerosol generated by the atomization unit 111R falls below the lower limit of the range of the desired amount, the control unit 53 notifies the light emitting element 40 that the desired amount of aerosol cannot be supplied. May be controlled. In addition, the control part 53 returns to the process of step S311 after step S319.

In step S320, the control unit 53 determines whether the first time has elapsed since the start of the supply of power output to the atomizing unit 111R. As described above, the first time is a time determined so that the supply amount of the aerosol does not exceed the upper limit of the range of the desired amount. When the determination result is YES, the control unit 53 proceeds to the process of step S321.
When the determination result is NO, the control unit 53 returns to the process of step S315.

In step S321, the control unit 53 stops supplying power output to the atomizing unit 111R. Here, when the supply amount of the aerosol generated by the atomization unit 111R falls below the lower limit of the range of the desired amount, the control unit 53 notifies the light emitting element 40 that the desired amount of aerosol cannot be supplied. May be controlled. In addition, the control part 53 returns to the process of step S311 after step S321. In the flow shown in FIG. 11, when returning to the process of step S <b> 311, even if the user operation on the operation interface 80 continues, the first switch 57.
Switches from on to off.

(Function and effect)
In the second modification, instead of the atomization switch 52, the first switch 57 and the second switch 5 are used.
Even if 8 is used, the same effect as the embodiment can be obtained. In addition, since the control for maintaining the supply amount of the aerosol so as to exceed the lower limit of the desired amount range using the second time described above is omitted, the power consumption and the processing load are reduced as compared with the embodiment. .
