  • FIG. 5 is a diagram for explaining the effect of shortening the wait time of a user attained by the inhaler device 100 according to the present embodiment.
  • the horizontal axis of a graph 30 represents the elapsed time since pressing of the power button.
  • the first duration is a duration of one second.
  • the second duration is a duration of three seconds. It is assumed that both the inhaler device 100 according to the present embodiment and the inhaler device according to the comparative example perform heating in accordance with the heating profile illustrated in FIG. 2 . In the heating profile illustrated in FIG. 2 , it is assumed that the length of the first not-ready-to-inhale period T 11 is 15 seconds.
  • a graph 31 which is an upper graph, shows example time-series changes in the heating state of the inhaler device according to the comparative example.
  • the inhaler device according to the comparative example does not supply electric power to the heater until the elapsed time since the start of holding down of the power button reaches three seconds. After the elapse of three seconds, the inhaler device according to the comparative example supplies electric power to the heater and performs full heating.
  • the time from when heating is started to when the temperature reaches the target temperature is 15 seconds, and therefore, the wait time from when the user starts holding down the power button to when the ready-to-inhale period starts is 18 seconds (3 seconds+15 seconds).
  • a graph 32 which is a lower graph, shows example time-series changes in the heating state of the inhaler device 100 according to the present embodiment.
  • the inhaler device 100 does not supply electric power to the heater until the elapsed time since the start of holding down of the power button reaches one second. After the elapse of one second, the inhaler device 100 supplies electric power to the heater and performs simplified heating. Subsequently, the inhaler device 100 performs full heating after the elapse of three seconds.
  • the time from when heating is started to when the temperature reaches the target temperature is 15 seconds, and therefore, the wait time from when the user starts holding down the power button to when the ready-to-inhale period starts is 16 seconds ( 1 second+15 seconds).
  • the wait time in the inhaler device 100 according to the present embodiment is shorter than the wait time in the inhaler device according to the comparative example by two seconds.
  • Two seconds by which the wait time is shortened corresponds to two seconds for which simplified heating is performed in the inhaler device 100 .
  • the inhaler device 100 according to the present embodiment performs simplified heating to thereby shorten the wait time from when the user starts holding down the power button to when the ready-to-inhale period starts, and a decrease in usability can be reduced.
  • the inhaler device 100 according to the present embodiment does not perform full heating unless the duration in which the power button is held down reaches the second duration. Therefore, safety of a level the same as that in the comparative example can be maintained.
  • the inhaler device 100 may stop heating by the heater 121 .
  • the start of the third duration is the same as the start of the first duration and that of the second duration. That is, the inhaler device 100 performs simplified heating when the duration in which the user continuously presses the power button reaches the first duration, performs full heating when the duration reaches the second duration, and stops full heating when the duration reaches the third duration.
  • safety can be improved with the present configuration. For example, accidental heating by the heater 121 can be prevented.
  • the inhaler device 100 may control the heater 121 so as not to perform heating until a fifth time period elapses. For example, when the number of times the power button is pressed for less than three seconds reaches three within 30 seconds (which corresponds to the fourth time period), the inhaler device 100 does not perform heating during the subsequent period of three minutes (which corresponds to the fifth time period) even when the power button is pressed. Taking into consideration the possibility that, for example, the power button is repeatedly pressed by another item in a bag or a child repeatedly presses the power button out of mischief, and the power button is unintentionally pressed, safety can be improved with the present configuration.
  • the notifier 113 provides first information. For example, at the timing when holding down of the power button starts, the notifier 113 provides as the first information, information indicating that the power button is pressed, by, for example, vibration, sound, or light. With the present configuration, the inhaler device 100 can make the user recognize that an instruction for starting power supply to the heater 121 is about to be input, thereby calling the user's attention.
  • the notifier 113 in response to detection of the second user operation, the notifier 113 provides second information. It is desirable that the second information be information different from the first information.
  • the notifier 113 provides as the second information, information indicating that full heating is started, by, for example, vibration, sound, or light. With the present configuration, the inhaler device 100 can make the user recognize that full heating is started, thereby calling the user's attention.
  • FIG. 6 is a flowchart of an example of the flow of a process performed by the inhaler device 100 according to the present embodiment.
  • the controller 116 first determines whether pressing of the power button is detected by the sensor 112 (step S 102 ). If it is determined that pressing of the power button is not detected (NO in step S 102 ), the process returns to step S 102 again. On the other hand, if it is determined that pressing of the power button is detected (YES in step S 102 ), the controller 116 controls the notifier 113 to provide information indicating that the power button is pressed (step S 104 ).
  • the controller 116 starts measuring the duration of pressing of the power button (step S 106 ).
  • the duration of pressing of the power button is a duration in which the power button is continuously pressed.
  • the controller 116 determines whether the measured duration of pressing of the power button reaches the first duration (step S 108 ). If it is determined that the duration of pressing of the power button does not reach the first duration (NO in step S 108 ), the process returns to step S 108 again. On the other hand, if it is determined that the duration of pressing of the power button reaches the first duration (YES in step S 108 ), the controller 116 controls the heater 121 to perform simplified heating (step S 110 ).
  • the controller 116 determines whether the measured duration of pressing of the power button reaches the second duration (step S 112 ). If it is determined that the duration of pressing of the power button does not reach the second duration (NO in step S 112 ), the controller 116 determines whether releasing of the power button is detected (step S 118 ). If it is determined that releasing of the power button is not detected (NO in step S 118 ), the process returns to step S 112 again. On the other hand, if it is determined that releasing of the power button is detected (YES in step S 118 ), the controller 116 controls the heater 121 to stop heating (step S 120 ), and the process ends. On the other hand, if it is determined that the duration of pressing of the power button reaches the second duration (YES in step S 112 ), the controller 116 controls the heater 121 to perform full heating (step S 114 ).
  • the controller 116 controls the notifier 113 to provide information indicating that full heating is started (step S 116 ).
  • FIG. 7 is a block diagram of a configuration example of an inhaler system 900 according to a second embodiment. As illustrated in FIG. 7 , the inhaler system 900 includes an inhaler device 910 and a control device 920 .
  • the inhaler device 910 includes a detector 911 and a heater 912 .
  • the detector 911 detects a user operation.
  • the heater 912 heats a substrate to thereby generate material to be inhaled by the user.
  • the control device 920 includes a controller 921 .
  • the controller 921 controls the heater 912 on the basis of a user operation detected by the detector 911 . Specifically, in response to the detector 911 detecting the first user operation, the controller 921 causes the heater 912 to operate in the first heating state. In response to the detector 911 detecting the second user operation different from the first user operation while the controller 921 is causing the heater 912 to operate in the first heating state, the controller 921 causes the heater 912 to operate in the second heating state different from the first heating state.
  • FIG. 8 is a flowchart of an example of the flow of the process performed by the control device 920 according to the present embodiment.
  • the control device 920 performs a process related to heating in the first heating state (step S 202 ). Specifically, the controller 921 causes the heater 912 to operate in the first heating state in response to the detector 911 detecting the first user operation.
  • control device 920 performs a process related to heating in the second heating state (step S 204 ). Specifically, in response to the detector 911 detecting the second user operation different from the first user operation while the controller 921 is causing the heater 912 to operate in the first heating state, the controller 921 causes the heater 912 to operate in the second heating state different from the first heating state.
  • the controller 921 causes the heater 912 to operate in the first heating state in response to detection of the first user operation and causes the heater 912 to operate in the second heating state in response to subsequent detection of the second user operation. That is, even when the first user operation is detected, the controller 921 does not cause the heater 912 to operate in the second heating state unless the second user operation is detected. Therefore, even when the user has performed the first user operation, the user can interrupt heating before a transition to the second heating state occurs, by not performing the second user operation. From this point of view, usability can be improved.
  • the present embodiment can also attain an effect similar to the effect attained by the first embodiment described above.
  • performing the first user operation is performing the predetermined user operation continuously for the first duration and performing the second user operation is performing the predetermined user operation continuously for the second duration
  • the present invention is not limited to such an example.
  • performing the first user operation may be performing the predetermined user operation.
  • Performing the second user operation may be performing the predetermined user operation continuously for the second duration.
  • the inhaler device 100 can start simplified heating without waiting for the duration in which the predetermined user operation is continuously performed reaches the first duration. Therefore, the wait time of the user can be further made shorter than that in the above-described embodiments.
  • the predetermined user operation may be pressing and releasing of the power button.
  • repeatedly pressing the power button for the first duration may be detected as the first user operation.
  • Repeatedly pressing the power button for the second duration may be detected as the second user operation.
  • an operation of, for example, touching a touch panel or rotating a rotary lever may be detected as the first user operation and the second user operation.
  • the inhaler device 100 may generate an aerosol by other means in addition to or instead of heating of the stick substrate 150 .
  • the inhaler device 100 may store an aerosol source that is a liquid, guides the aerosol source to the heater 121 , and heats and atomizes the aerosol source to thereby generate an aerosol.
  • any means, such as induction heating or vibration atomization may be employed in addition to heating.
  • a program that is the software is stored in advance in, for example, a recording medium (non-transitory medium) that is included in each device or that is externally provided.
  • Each program is loaded to a RAM upon execution by a computer and executed by a processor such as a CPU.
