[0004] [Patent Document 1] JP 2020-68762 A [Patent Document 2] JP 2020-68690 A Summary of the Invention [Problem to be solved by the invention]

[0005] When an error occurs in a device, the user may be notified of the occurrence of the error using multiple display units. However, in such cases, conventionally, each of the multiple display units is given a meaning, and the meaning is notified using a display unit among the multiple display units that has a meaning corresponding to the error that has occurred. Therefore, it has not been possible to notify a user of the occurrence of an error in a device using multiple display units that do not have a meaning individually.

[0006] An object of the present invention is to notify a user that an error has occurred in a device by using a plurality of display units, each of which has no meaning individually. [Means for solving the problem]

[0007] With this objective in mind, the present invention provides an inhalation device comprising a heating unit that generates an aerosol by heating a substrate holding an aerosol source using power from a battery, a plurality of display units for displaying the status of the device while the device is operating, and a control unit that, when an error occurs in the device, controls the plurality of display units to display a message indicating that an error has occurred, and controls all or part of the plurality of display units to be lit for a predetermined period and then turned off for a predetermined period.

[0008] The multiple display sections may be arranged in series.

[0009] The action may be at least one of heating the substrate, inhaling the aerosol, reporting the remaining battery charge, and charging the battery.

[0010] The error may be an error caused by the temperature of the device being outside a predetermined temperature range. In this case, the control unit may control the display units to display the occurrence of an error when an operation for heating the substrate is performed in a state where an error has occurred. The operation for heating the substrate may be at least one of an operation for opening a shutter of an opening into which the substrate is inserted and an operation for pressing a button for heating the substrate. The control unit may also control the display units not to display the occurrence of an error when an operation for closing the shutter is performed. Furthermore, the control unit may control the display units to display the occurrence of an error again if the button is pressed after the occurrence of an error is no longer displayed on the display units with the shutter open, if the error has not been resolved.

[0011] The present invention also provides a display device including a plurality of display units for displaying the status of an apparatus while the apparatus is operating, and a control unit that, when an error occurs in the apparatus, controls the plurality of display units to display a message indicating that an error has occurred, and to cause all or part of the plurality of display units to be lit for a predetermined period and then turned off for a predetermined period.

[0012] The multiple display sections may be arranged in series.

[0013] Furthermore, the present invention also provides a display method including the steps of: displaying the status of the device on a plurality of display units when the device is operating; and, when an error occurs in the device, displaying a message indicating that an error has occurred on the plurality of display units in a display mode in which all or part of the plurality of display units are lit for a predetermined period and then turned off for a predetermined period.

[0014] Furthermore, the present invention also provides a program for enabling a computer to realize a function of displaying the status of the device on a plurality of display units when the device is operating, and a function of displaying, when an error occurs in the device, a message indicating that an error has occurred on the plurality of display units in a display mode in which all or part of the plurality of display units are lit for a predetermined period of time and then turned off for a predetermined period of time. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018] [Example of the external configuration of the suction device] 1(a) and (b) are overall perspective views of the suction device 1 in this embodiment. FIG. 1(a) shows an overall perspective view from diagonally above, and FIG. 1(b) shows an overall perspective view from diagonally below. As shown in the figures, the suction device 1 includes a panel 10, a main body housing 20 to which the panel 10 is detachable, and a shutter 50. The panel 10 and the main body housing 20 are formed of separate members. The panel 10 includes a display window 60 formed of a transparent material on its surface. The main body housing 20 accommodates the main body 30 of the suction device 1. The main body housing 20 also includes an external connection terminal 70 such as a USB Type-C connector.

[0019] The panel 10 is attached to the main body housing 20 to form the outermost housing 40 of the suction device 1. Furthermore, by including the panel 10, the suction device 1 can buffer heat released to the outside even when the main body 30 generates heat. In other words, the panel 10 functions to insulate heat generated from the heating portion of the main body 30. Furthermore, the panel 10 is formed so that its surface is substantially curved. Then, when attached to the main body housing 20, the panel 10 defines an internal space together with the surface of the main body housing 20.

[0020] The housing 40 is preferably sized to fit in the user's hand. The user holds the suction device 1 in one hand with the fingertip in contact with the surface of the panel 10. When the user presses the surface of the panel 10 with the fingertip, the panel 10 deforms to form a recess toward the main housing 20. As a result of such deformation of the panel 10, a protrusion on the panel 10 comes into contact with an operation button provided on the surface of the main housing 20, and the operation button is pressed down. That is, the portion of the surface of the panel 10 that is pressed with the fingertip forms the button area 15.

[0021] In order for the user to deform the panel 10, for example, it is necessary to simultaneously press the button area 15 using multiple fingers. For example, a larger pressing force is required compared to a case where a user presses a single button protruding from the surface of the housing with a single finger. That is, the suction device 1 in this embodiment is advantageous in that it can prevent unintended erroneous operations by the user, including the operation button being pressed accidentally in a bag. In addition, the pressing force of a child that is not appropriate for the user of the suction device 1 cannot easily press the button area 15 of the panel 10, so it is also advantageous in terms of preventing tampering (child resistance).

[0022] The main housing 20 has an opening into which the stick-shaped substrate is inserted, and in FIG. 1, the shutter 50 is shown closing the opening. The shutter 50 has a slide mechanism and is movable along the surface of the outer shell between a first position where the opening is closed and a second position where the opening is open. The opening and closing of the opening can be detected by providing a sensor (not shown) near the first position and / or the second position. For example, a magnet is disposed in the shutter 50, and the opening and closing of the opening are detected by a magnetic sensor.

[0023] The opening is opened by the user placing his / her finger on the shutter 50 and sliding it along the side surface. As a result of the opening being opened, the user can insert the stick-shaped base material. After inserting the stick-shaped base material, the user can press the surface of the panel 10 with his / her finger and press the operation button to turn on the power of the suction device 1.

[0024] [External configuration examples of the panel and main housing] 2(a) and (b) are external views of the panel 10 and main body housing 20 of the suction device 1. Fig. 2(a) shows an external view of the inner surface of the panel 10, and Fig. 2(b) shows an external view of the outer surface of the main body housing 20. When the panel 10 is attached to the main body housing 20, the inner surface of the panel 10 and the outer surface of the main body housing 20 face each other.

[0025] As shown in FIG. 2(a), magnets 11, protrusions 12, magnets 13, and magnets 14 are arranged along the longitudinal direction on the inner surface of panel 10. When panel 10 is attached to main housing 20, magnets 11 and 14 attract panel 10 to main housing 20 by their magnetic force (magnetic attraction). This holds panel 10 to main housing 20. Protrusion 12 presses operation button 22 provided on the surface of main housing 20. Magnet 13 is configured as a magnetic field application unit for the sensor unit of main body 30. In other words, panel 10 is detected by detecting the magnetic force of the magnetic field applied by magnet 13 with magnetic sensor 23 of main housing 20.

[0026] 2(b), on the outer surface of the main housing 20, the magnet 21, the passage hole 25, the operation button 22, and the magnet 24 are arranged along the longitudinal direction from the shutter 50 side. Also, on the inner surface of the main housing 20 (more precisely, on a substrate that is substantially zero distance from the inner surface), a magnetic sensor 23 is arranged at a position between the operation button 22 and the magnet 24 along the longitudinal direction. The magnet 21, the operation button 22, the magnetic sensor 23, and the magnet 24 of the main housing 20 correspond to the magnet 11, the protrusion 12, the magnet 13, and the magnet 14 of the panel 10, respectively. In other words, when the panel 10 is attached to the main housing 20, they are aligned with each other and face each other.

[0027] The magnets 21 and 24 of the main housing 20 are attracted to the magnets 11 and 14 of the panel 10, respectively, by their magnetic force (magnetic attraction). In other words, the magnets 11 and 21, and the magnets 14 and 24 attract each other, thereby holding the panel 10 in a mountable state to the main housing 20. It is preferable that the magnets 11 and 14 of the panel 10, and the magnets 21 and 24 of the main housing 20 are made of permanent magnets.

[0028] The operation button 22 is provided on the surface to which the panel 10 is attached. In other words, when the panel 10 is attached to the main body housing 20, the operation button 22 is covered by the panel 10 and is pressed by the protrusion 12 of the panel 10. This allows, for example, the power of the suction device 1 to be switched on and off.

[0029] The magnetic sensor 23 detects a magnetic force based on a magnetic field applied from the magnet 13 in the panel 10. For example, the magnetic sensor 23 is preferably a Hall sensor configured using a Hall element. This makes it possible to detect attachment of the panel 10 to the main body housing 20.

[0030] The magnetic sensor 23 of the main housing 20 is disposed so as to face the magnet 13 of the panel 10 via the inner surface of the main housing 20 when the panel 10 is attached to the main housing 20. In other words, when the panel 10 is attached to the main housing 20, the distance between the magnetic sensor 23 of the main housing 20 and the magnet 13 of the panel 10 is minimized.

[0031] Furthermore, the magnetic sensor 23 of the main housing 20 is configured not to detect the magnetic fields generated by the two magnets 21 and 24 of the main housing 20. Specifically, it is preferable to dispose the magnetic sensor 23 on the inner surface of the main housing 20 at a position separated from the two magnets 21 and 24 on the outer surface of the main housing 20. This makes it possible to reduce the influence of the magnetic fields from the two magnets 21 and 24 on the magnetic sensor 23 to approximately zero.

[0032] Furthermore, it is preferable to configure the distance between the magnetic sensor 23 and the magnet 24 (or magnet 21) in the main housing 20 to be greater than the distance between the magnet 13 and the magnetic sensor 23 in a state in which the panel 10 is attached to the main housing 20. This allows the magnetic sensor 23 to appropriately take into account only the effect of the magnetic field applied from the magnet 13, without taking into account the effect of the magnetic field of the magnet 24, when detecting the attachment of the panel 10 to the main housing 20.

[0033] The through hole 25 is an opening aligned with one or more LEDs (Light Emitting Diodes) arranged in the main body 30, and allows light from the LEDs to pass through to the display window 60 of the panel 10. This allows a user to view the light from the outer surface of the panel 10.

[0034] [Example of suction device configuration] 3 is a schematic diagram showing a configuration example of the inhalation device 1. In the inhalation device 1, for example, a stick-type substrate 100 having a flavor-generating substrate such as an aerosol source that is a source of inhaled components and a filling containing a flavor source is inserted. The aerosol source is not limited to a liquid, and may be a solid. The inserted stick-type substrate 100 generates an aerosol containing a flavor by being heated from its outer periphery.

[0035] 3, the suction device 1 includes a control unit 90, a power supply unit 91, a sensor unit 92, a notification unit 93, a storage unit 94, a communication unit 95, a holding unit 80, a heating unit 81, and a heat insulating unit 82. These elements of the suction device 1 are housed in the main body 30 shown in FIG.

[0036] The control unit 90 functions as an arithmetic processing unit and a control unit, and controls the overall operation within the suction device 1 in accordance with various programs. The control unit 90 is realized by electronic circuits such as a CPU (Central Processing Unit) and a microprocessor.

[0037] The power supply unit 91 accumulates power. Then, the power supply unit 91 supplies power to each component of the suction device 1 based on the control of the control unit 90. The power supply unit 91 may be configured by, for example, a rechargeable battery such as a lithium ion secondary battery.

[0038] The sensor unit 92 acquires various information related to the suction device 1. As one example, the sensor unit 92 is configured with a pressure sensor such as a microphone capacitor, a flow rate sensor, a temperature sensor, or the like, and acquires values ​​associated with suction by the user. As another example, the sensor unit 92 is configured with an input device such as a button or a switch that accepts information input from the user.

[0039] The sensor unit 92 also detects the attachment of the panel to the main body housing. For example, the sensor unit 92 is configured with a magnetic sensor (for example, a Hall sensor using a Hall element that detects magnetism using the Hall effect). The sensor unit 92 detects that a panel having a magnetic field application unit (for example, a magnet and / or a magnetic material) that applies a magnetic field to the magnetic sensor is in the vicinity of the sensor unit 92.

[0040] The notification unit 93 notifies the user of information. The notification unit 93 is configured by, for example, a display unit made of light-emitting elements such as LEDs, a display device that displays images, a sound output device that outputs sounds, or a vibration device that vibrates.

[0041] For example, the LED emits light in a predetermined light emission manner to notify the user of the operation information of the suction device 1. Specifically, the LED emits light to notify the user of the state of whether the suction device 1 is powered on, the progress of preheating, the suction status (remaining time available for suction, etc.), and the current operation mode of the suction device 1 (for example, the suction mode and / or the communication mode, etc.).

[0042] The storage unit 94 stores various information for the operation of the suction device 1. The storage unit 94 is configured, for example, with a non-volatile storage medium such as a flash memory. The storage unit 94 also stores computer-executable instructions for operating the suction device 1, as well as programs such as firmware.

[0043] The communication unit 95 is a communication interface capable of performing communication conforming to any wired or wireless communication standard. In the case of wireless communication, for example, Wi-Fi (registered trademark) or Bluetooth (registered trademark) may be adopted as such a communication standard. In the case of wired communication, for example, a data communication cable is connected via the external connection terminal 70. This allows input / output of data related to the operation of the suction device 1 to and from an external device.

[0044] The communication unit 95 may activate a communication function when the opening 84 of the shutter 50 is opened, and start communication with an external terminal using Bluetooth (registered trademark) or the like. Also, the communication with the external terminal may be terminated when the opening 84 of the shutter 50 is closed. The Bluetooth (registered trademark) connection between the communication unit 95 and the external terminal is preferably a connection using BLE (Bluetooth Low Energy).

[0045] The holding part 80 has an internal space 83, and holds the stick-type substrate 100 while accommodating a portion of the stick-type substrate 100 in the internal space 83. The holding part 80 has an opening 84 that connects the internal space 83 to the outside, and holds the stick-type substrate 100 inserted into the internal space 83 from the opening 84. For example, the holding part 80 is a cylindrical body with the opening 84 and a bottom part 85 as its bottom surface, and defines a columnar internal space 83. In this specification, the direction in which the stick-type substrate 100 is inserted into the internal space 83 is defined as the longitudinal direction of the suction device 1.

[0046] The holding part 80 has a pressing part and a non-pressing part (neither shown) along the longitudinal direction on the inner wall of the internal space 83. When the internal space 83 receives the stick-shaped substrate 100, the pressing part presses the stick-shaped substrate 100 in a direction perpendicular to the longitudinal direction. The stick-shaped substrate 100 is then clamped by the holding part 80 while being pressed and deformed by the pressing part. As a result, the stick-shaped substrate 100 is heated from the outer periphery by the heating part 81 while being pressed.

[0047] On the other hand, a gap (not shown) is formed between the non-pressed portion and the stick-shaped substrate 100. As a result, the opening 84 and the bottom 85 communicate with each other through the gap.

[0048] The holding part 80 also has the function of defining a flow path for air to be supplied to the stick-type substrate 100. An air inlet hole 86, which is the entrance of air to this flow path, is an opening 84. More precisely, the air inlet hole 86 is a gap between the non-pressure part and the stick-type substrate 100. Air that flows in from the air inlet hole 86 as the user inhales is transported along the dotted arrow through the stick-type substrate 100 to an air outlet hole 87, which is the exit for air from the flow path.

[0049] The stick-type substrate 100 includes a substrate portion 101 and a mouthpiece portion 102. The substrate portion 101 includes an aerosol source. When the stick-type substrate 100 is held by the holder 80, at least a part of the substrate portion 101 is accommodated in the internal space 83, and at least a part of the mouthpiece portion 102 protrudes from the opening 84. When the user holds the mouthpiece portion 102 protruding from the opening 84 in his / her mouth and inhales, air flows into the internal space 83 from the air inlet hole 86, and is transported to the air outlet hole 87 of the mouthpiece portion 102 via the bottom portion 85 along the arrow indicated by the dotted line, and reaches the oral cavity of the user together with the aerosol generated from the substrate portion 101. The stick-type substrate 100 is an example of a substrate for holding an aerosol source.

[0050] The heating unit 81 heats the aerosol source to atomize the aerosol source and generate aerosol. The heating unit 81 is configured in a film shape and is arranged to cover the outer periphery of the holding unit 80. When the heating unit 81 generates heat, the substrate unit 101 of the stick-type substrate 100 is heated from the outer periphery, and an aerosol is generated. The heating unit 81 generates heat when power is supplied from the power supply unit 91. As an example, power may be supplied when the sensor unit 92 detects that the user has started inhaling, that a predetermined user input operation has been received, and / or that predetermined information has been input. When the sensor unit 92 detects that the user has stopped inhaling, that a predetermined user input operation has been received, and / or that predetermined information has been input, the supply of power may be stopped. The heating unit 81 is an example of a heating unit that generates aerosol by heating the substrate with power from a battery.

[0051] The heat insulating section 82 prevents heat transfer from the heating section 81 to other components. For example, the heat insulating section 82 is made of a vacuum heat insulating material, an aerogel heat insulating material, or the like.

[0052] The above describes an example of the configuration of the suction device 1. Of course, the configuration of the suction device 1 is not limited to the above, and various configurations such as those exemplified below may be used.

[0053] As one example, the heating unit 81 may be configured in a blade shape and disposed so as to protrude from the bottom 85 of the holding unit 80 into the internal space 83. In this case, the blade-shaped heating unit 81 is inserted into the substrate 101 of the stick-type substrate 100 and heats the substrate 101 of the stick-type substrate 100 from the inside. As another example, the heating unit 81 may be disposed so as to cover the bottom 85 of the holding unit 80. Furthermore, the heating unit 81 may be configured as a combination of two or more of a first heating unit covering the outer periphery of the holding unit 80, a blade-shaped second heating unit, and a third heating unit covering the bottom 85 of the holding unit 80.

[0054] Furthermore, the means for atomizing the aerosol source is not limited to heating by the heating unit 81. For example, the means for atomizing the aerosol source may be induction heating.

[0055] [Overview of the suction device's operation] In the present embodiment, the notification unit 93 of the suction device 1 described above is configured with a plurality of display units for displaying the state of the device itself when the device itself is operating. When an error occurs in the device itself, the control unit 90 controls the plurality of display units to display the occurrence of the error in a display mode in which all or a part of the plurality of display units are turned on for a predetermined period and then turned off for a predetermined period.

[0056] Here, the operation is a normal operation, and may be at least one of an operation of heating the stick-shaped substrate 100, an operation of inhaling an aerosol, an operation of notifying the remaining charge of the rechargeable battery of the power supply unit 91, and an operation of charging the rechargeable battery of the power supply unit 91.

[0057] The error may be an error caused by the temperature of the device itself being outside a predetermined temperature range, or an error of a warning level in the system of the device itself, an error that cannot be recovered from by any operation on the device itself or the passage of time, or an error caused by a member protecting the device itself being removed.

[0058] Here, the multiple display units are N LEDs (N is a natural number).

[0059] Furthermore, a warning-level error in the system of the device itself is called a "system error." An error caused by the temperature of the device itself being outside a predetermined temperature range is called a "temperature error." An error that cannot be recovered from either by operating the device itself or by the passage of time is called a "permanent failure error." An error caused by the removal of a member that protects the device itself is called a "panel error," taking the panel 10 as an example of the member that protects the device itself. However, the member that protects the device itself is not limited to the panel 10, and may be any member.

[0060] Furthermore, a display mode in which all or some of the N LEDs are turned on for a predetermined period and then turned off for a predetermined period is referred to as an "animation mode."

[0061] Thus, there are system errors, temperature errors, permanent failure errors, and panel errors. When any error occurs, the occurrence of the error may be displayed in an animation format. However, in the following description, it is assumed that when a temperature error occurs, the occurrence of the error is displayed in an animation format on N LEDs.

[0062] [Example of normal operation of suction device] As normal operations of the inhalation device 1, the operation of preheating the stick-shaped substrate 100, the operation of inhaling the aerosol, the operation of notifying the remaining charge of the rechargeable battery of the power supply unit 91, and the operation of charging the rechargeable battery of the power supply unit 91 will be described as examples.

[0063] 4(a) to 4(e) are diagrams showing display examples of N LEDs 600 visible through the display window 60 when the suction device 1 performs an operation of preheating the stick-type substrate 100. Here, the operation of preheating the stick-type substrate 100 is an example of an operation of heating the stick-type substrate 100.

[0064] 4(a), all of the N LEDs 600 are turned off. In this state, when the user presses the button region 15 for several seconds, the suction device 1 starts the operation of preheating the stick-type substrate 100.

[0065] When the suction device 1 starts the operation of preheating the stick-type substrate 100, the N LEDs 600 light up the LEDs that are off from the bottom up, and the number of lit LEDs gradually increases to indicate the progress of the preheating. For example, FIG. 4(b) shows a display when a quarter of the preheating time has elapsed, and a quarter of the N LEDs 600 are lit. FIG. 4(c) shows a display when two-quarters of the preheating time has elapsed, and two-quarters of the N LEDs 600 are lit. FIG. 4(d) shows a display when three-quarters of the preheating time has elapsed, and three-quarters of the N LEDs 600 are lit. FIG. 4(e) shows a display when the preheating time has ended, and all of the N LEDs 600 are lit.

[0066] 5(a) to (e) are diagrams showing examples of display of N LEDs 600 visible through the display window 60 when the inhalation device 1 performs an operation of inhaling an aerosol.

[0067] Before the aerosol is inhaled, all of the N LEDs 600 are lit, as shown in Fig. 5(a). In this state, the inhalation device 1 starts an operation of causing the user to inhale the aerosol generated by heating the stick-type substrate 100.

[0068] When the inhalation device 1 starts the operation of inhaling the aerosol, the N LEDs 600 turn off the lit LEDs from the top, and the number of lit LEDs is gradually reduced to indicate the decrease in the remaining time available for inhalation. For example, FIG. 5(b) shows the display when one-quarter of the inhalation period has elapsed, and three-quarters of the N LEDs 600 are lit. FIG. 5(c) shows the display when two-quarters of the inhalation period has elapsed, and two-quarters of the N LEDs 600 are lit. FIG. 5(d) shows the display when three-quarters of the inhalation period has elapsed, and one-quarter of the N LEDs 600 are lit. FIG. 5(e) shows the display when the inhalation period has ended, and all of the N LEDs 600 are lit.

[0069] 6(a) to (e) are diagrams showing examples of the display of N LEDs 600 visible through the display window 60 when the suction device 1 performs an operation to notify the remaining charge of the rechargeable battery of the power supply unit 91 (hereinafter referred to as "battery charge remaining").

[0070] 6(a), all of the N LEDs 600 are turned on. In this state, the inhalation device 1 starts using the rechargeable battery.

[0071] When the suction device 1 starts using the rechargeable battery, the N LEDs 600 turn off the lit LEDs from the top, and the number of lit LEDs is gradually reduced to indicate the decrease in the remaining battery charge. For example, FIG. 6(b) shows a display when the remaining battery charge is 75%, in which three-quarters of the N LEDs 600 are lit. FIG. 6(c) shows a display when the remaining battery charge is 50%, in which two-quarters of the N LEDs 600 are lit. FIG. 6(d) shows a display when the remaining battery charge is 25%, in which one-quarter of the N LEDs 600 are lit. FIG. 6(e) shows a display when the remaining battery charge is such that one stick-shaped substrate 100 can be suctioned, in which the lower LED of the N LEDs 600 is blinking.

[0072] 7(a) to (e) are diagrams showing examples of display of N LEDs 600 visible through the display window 60 when the suction device 1 is performing an operation of charging the rechargeable battery of the power supply unit 91. FIG.

[0073] 7(a), all of the N LEDs 600 are turned off. In this state, when the user connects the USB cable 700 to the external connection terminal 70, the suction device 1 starts the operation of charging the rechargeable battery.

[0074] When the suction device 1 starts charging the rechargeable battery, the N LEDs 600 light up in order from the bottom up, and the number of lit LEDs gradually increases to indicate the progress of charging the rechargeable battery. For example, FIG. 7(b) shows a display when the rechargeable battery is 25% charged, with one-quarter of the N LEDs 600 lit. FIG. 7(c) shows a display when the rechargeable battery is 50% charged, with two-quarters of the N LEDs 600 lit. FIG. 7(d) shows a display when the rechargeable battery is 75% charged, with three-quarters of the N LEDs 600 lit. FIG. 7(e) shows a display when charging of the rechargeable battery is completed, with all of the N LEDs 600 lit.

[0075] [Example of operation when an error occurs in the suction device] An example of the operation of the suction device 1 when an error occurs will be described below with reference to the operation when a temperature error occurs. In the following, eight LEDs arranged in a vertical row will be taken as an example of the N LEDs 600, and these eight LEDs will be referred to as LED#8, LED#7, . . . , LED#1 from the top.

[0076] If a temperature error occurs when a user performs an operation to heat the aerosol source held by the stick-shaped substrate 100, the control unit 90 displays that fact on the eight LEDs 600. Here, the operation to heat the aerosol source is, for example, an operation to open the shutter 50 or an operation to press the button area 15. Then, when the temperature state changes and the temperature reaches a level at which the device can operate, the temperature error is released.

[0077] FIG. 8 is a diagram showing an example of an animation display of eight LEDs 600 when a temperature error occurs.

[0078] As shown in the figure, initially, the control unit 90 sets the display of LEDs #1 to #8 to state 601. That is, the control unit 90 normally lights up LEDs #1 to #8 as shown by dot hatching in a thick solid line frame. Then, 400 milliseconds later, the control unit 90 changes the display of LEDs #1 to #8 to state 602. That is, the control unit 90 turns off LEDs #1 to #8 as shown by the white background in a thin solid line frame.

[0079] Furthermore, 200 milliseconds later, the control unit 90 changes the display of LEDs #1 to #8 to state 603. That is, the control unit 90 causes LEDs #1 to #8 to be normally lit as shown by the dotted hatching in the thick solid line frame. Then, 400 milliseconds later, the control unit 90 changes the display of LEDs #1 to #8 to state 604. That is, the control unit 90 causes LEDs #1 to #8 to be turned off as shown by the white background in the thin solid line frame.

[0080] Furthermore, 200 milliseconds later, the control unit 90 changes the display of LEDs #1 to #8 to state 605. That is, the control unit 90 causes LEDs #1 to #8 to be normally lit as shown by the dotted hatching in the thick solid line frame. Then, 400 milliseconds later, the control unit 90 changes the display of LEDs #1 to #8 to state 606. That is, the control unit 90 causes LEDs #1 to #8 to be turned off as shown by the white background in the thin solid line frame.

[0081] Furthermore, after 3000 milliseconds, the control unit 90 changes the display of LEDs #1 to #8 again to state 601. That is, the control unit 90 causes LEDs #1 to #8 to be normally lit as indicated by dotted hatching within a thick solid line frame.

[0082] The control unit 90 then repeats three times the display pattern of going from state 601 through states 602 to 606 and back to state 601. That is, the control unit 90 displays such a display pattern three times, with each pattern lasting 4600 milliseconds.

[0083] In this specification, turning on an LED normally means turning on the LED with a duty ratio of 100%, for example, and turning off an LED means setting the duty ratio of the LED to 0%.

[0084] The control unit 90 may interrupt the display if the shutter 50 is closed before such display ends. Also, the control unit 90 may perform such display again if the button area 15 is pressed after such display ends with the shutter 50 open.

[0085] In this embodiment, all of the eight LEDs 600 are turned on for a predetermined period and then turned off for a predetermined period, but this is not limiting. A part of the eight LEDs 600 may be turned on for a predetermined period and then turned off for a predetermined period. In this case, each time a part of the eight LEDs 600 is turned on, the part that is turned on may be changed, so that the lit LEDs appear to move.

[0086] [Details of operation when an error occurs in the suction device] FIG. 9 is a flowchart showing an example of the operation of the control unit 90 of the suction device 1 in this embodiment when a temperature error occurs.

[0087] As shown in the figure, the control unit 90 first determines whether or not an operation to open the shutter 50 has been performed (step 901). If it is determined that an operation to open the shutter 50 has not been performed, the control unit 90 repeats step 901. If it is determined in step 901 that an operation to open the shutter 50 has been performed, the control unit 90 determines whether or not a temperature error has occurred (step 902).

[0088] If it is determined in step 902 that a temperature error has occurred, the control unit 90 turns on and off the LEDs #1 to #8 in an animation manner (step 903). For example, the control unit 90 turns on the LEDs #1 to #8, turns them off after 400 milliseconds, turns them on again after 200 milliseconds, turns them off after 400 milliseconds, turns them on again after 200 milliseconds, and turns them off again after 400 milliseconds.

[0089] Then, the control unit 90 judges whether or not an operation to close the shutter 50 has been performed (step 904). If it is judged that an operation to close the shutter 50 has been performed, the control unit 90 ends the process without executing the turning on and off in the animation mode of step 903 again. If it is not judged in step 904 that an operation to close the shutter 50 has been performed, the control unit 90 judges whether or not 3000 milliseconds have elapsed (step 905). If it is not judged that 3000 milliseconds have elapsed, the control unit 90 repeats step 905. If it is judged in step 905 that 3000 milliseconds have elapsed, the control unit 90 judges whether or not step 903 has been executed three times (step 906). If it is not judged that step 903 has been executed three times, the control unit 90 returns the process to step 903 and executes the turning on and off in the animation mode of step 903 again.

[0090] If it is determined in step 906 that step 903 has been executed three times, the control unit 90 determines whether or not an operation of pressing the button area 15 has been performed (step 907). If it is determined that an operation of pressing the button area 15 has been performed, the control unit 90 returns the process to step 903, and repeats steps 903 to 906. If it is not determined in step 907 that an operation of pressing the button area 15 has been performed, the control unit 90 determines whether or not the temperature of the own device has reached an operable temperature (step 908). If it is not determined that the temperature of the own device has reached an operable temperature, the control unit 90 returns the process to step 907. If it is determined in step 908 that the temperature of the own device has reached an operable temperature, the temperature error is released, and the control unit 90 ends the process.

[0091] On the other hand, if it is determined in step 902 that a temperature error has not occurred, the control unit 90 determines whether or not an operation to press the button area 15 has been performed (step 909). If it is determined that an operation to press the button area 15 has been performed, the control unit 90 repeats step 909. If it is determined in step 909 that an operation to press the button area 15 has been performed, the control unit 90 determines whether or not a temperature error has occurred (step 910).

[0092] If it is determined in step 910 that a temperature error has occurred, the control unit 90 advances the process to step 903. The process contents of steps 903 to 908 have already been described, so a description thereof will be omitted here.

[0093] On the other hand, if it is determined in step 910 that a temperature error has not occurred, the control unit 90 ends the process.

[0094] [Variations] In the above, the N LEDs 600 are arranged in a vertical line, but this is not limited to the above. For example, the N LEDs 600 may be arranged in any shape as long as they are arranged continuously. For example, the N LEDs 600 may be arranged in a circular ring shape. Alternatively, the N LEDs 600 may not be arranged continuously, but may be arranged discretely.

[0095] In addition, the above describes the case where the present invention is applied to a heated tobacco product, but the present invention is not limited thereto. The present invention is applied to various inhalation devices for inhaling aerosols, such as electronic cigarettes and nebulizers. In addition, the inhaled components generated may include gases such as invisible steam, in addition to aerosols. Furthermore, the present invention may be applied to a display device that is connected to a device other than an inhalation device and displays information about the device. In that case, the N LEDs 600 are an example of a plurality of display units for displaying the status of the device when the device is operating. And the control unit 90 is an example of a control unit that controls the plurality of display units to display the occurrence of an error in a display mode in which all or a part of the plurality of display units are turned on for a predetermined period and then turned off for a predetermined period when an error occurs in the device.

[0096] [Advantages of this embodiment] In the suction device 1 of this embodiment, when the device is operating, the state of the device itself is displayed on the multiple display units, and when an error occurs in the device itself, the occurrence of the error is displayed on the multiple display units in a display mode in which all or part of the multiple display units are turned on for a predetermined period and then turned off for a predetermined period. As a result, in this embodiment, it is possible to notify the user that an error has occurred in the device by using multiple display units that each have no meaning. [Explanation of symbols]
