[0004] [Patent Document 1] Japanese Patent Publication No. 2020-68762 [Patent Document 2] Japanese Patent Application Publication No. 2020-68690 Summary of the Invention [Problem to be solved by the invention]

[0005] The device status when the device is operating includes, for example, the remaining battery level and the battery charging status. When displaying such status, it is easy to understand if it is displayed by showing the progress of a number of display sections arranged in a row.

[0006] Furthermore, there are various types of errors that can occur in devices. When an error occurs in a device and a message is displayed to indicate that an error has occurred, multiple display units arranged in a row can be displayed in various ways, making it easy to understand that an error has occurred.

[0007] If a configuration is adopted in which multiple display units that display the status of the device when the device is operating and the occurrence of an error when an error occurs in the device are not arranged in a row, it is not possible to clearly display the status of the device and the occurrence of an error.

[0008] An object of the present invention is to clearly display the state of a device when the device is operating, and to clearly display the occurrence of an error when an error occurs in the device. [Means for solving the problem]

[0009] With this objective in mind, the present invention provides an inhalation device comprising: a heating unit that generates an aerosol by heating a substrate that holds an aerosol source using power from a battery; a plurality of display units that display the status of the device; and a control unit that, when a first error occurs in the device, controls the plurality of display units to display the fact that the first error has occurred in a first display mode in which first and second portions of the plurality of display units are turned on and a third portion sandwiched between the first and second portions of the plurality of display units is turned off, and, when a second error occurs in the device, controls the plurality of display units to display the fact that the second error has occurred in a second display mode in which the first, second, and third portions are turned on.

[0010] In this case, the second display mode may include a display mode in which the plurality of display units are turned on for a predetermined period and then turned off for a predetermined period. The second display mode may include a display mode in which all of the plurality of display units are turned on for a predetermined period and then turned off for a predetermined period. Alternatively, the second display mode may include a display mode in which some of the plurality of display units are turned on for a predetermined period and then turned off for a predetermined period.

[0011] In this case, the first portion may include one display unit at one end of the plurality of display units, and the second portion may include one display unit at the other end of the plurality of display units.

[0012] In this case, the control unit may be configured to control the multiple display units to display in a second display mode a message indicating that a second error has occurred when a second error of warning level occurs in the system of the device.

[0013] In this case, the control unit may be configured to control the display units to display, in a second display mode, a message indicating that the second error has occurred when the temperature of the device is outside a predetermined temperature range, and to control the display units to display, in a second display mode, a message indicating that the second error has occurred when an operation to heat the aerosol source is performed while the second error has occurred.

[0014] Furthermore, in this case, the control unit may be configured to control the multiple display units to display in a first display mode a message indicating that a first error has occurred when an irrecoverable first error occurs due to an operation on the device itself.

[0015] The present invention also provides a display method for an inhalation device that has a heating unit that generates an aerosol by heating a substrate that holds an aerosol source using power from a battery, and a plurality of display units for displaying the status of the device, the display method including the steps of: when a first error occurs in the device, displaying on the plurality of display units in a first display mode that the first error has occurred, lighting up the first and second portions of the plurality of display units, and turning off the third portion sandwiched between the first and second portions of the plurality of display units; and when a second error occurs in the device, displaying on the plurality of display units in a second display mode that the second error has occurred, lighting up the first, second, and third portions.

[0016] Furthermore, the present invention also provides a program that enables an inhalation device having a heating unit that generates an aerosol by heating a substrate that holds an aerosol source using power from a battery and a plurality of display units for displaying the status of the device to realize the following functions: when a first error occurs in the device, the plurality of display units display the fact that a first error has occurred in a first display mode in which the first and second parts of the plurality of display units are turned on and the third part sandwiched between the first and second parts of the plurality of display units is turned off; and when a second error occurs in the device, the plurality of display units display the fact that a second error has occurred in a second display mode in which the first, second and third parts are turned on. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0020] [Example of the external configuration of the suction device] 1(a) and (b) are overall perspective views of the suction device 1 according to the present 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, 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 separate members. The panel 10 includes a display window 60 made of a transparent material on its surface. The main body housing 20 houses 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.

[0021] 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 approximately curved. When attached to the main body housing 20, the panel 10, together with the surface of the main body housing 20, defines an interior space.

[0022] The housing 40 is preferably sized to fit in a user's hand. The user holds the suction device 1 in one hand with their fingertip in contact with the surface of the panel 10. When the user presses the surface of the panel 10 with their fingertip, the panel 10 deforms to form a recess toward the main housing 20. As a result of this deformation of the panel 10, a protrusion on the panel 10 comes into contact with an operation button on the surface of the main housing 20, thereby pressing the operation button. In other words, the portion of the surface of the panel 10 that is pressed with the fingertip forms a button area 15.

[0023] In order for a user to deform panel 10, for example, multiple fingers must be used to simultaneously press button region 15. This requires a greater pressing force than, for example, a single button protruding from the surface of the housing pressed by a single finger. That is, suction device 1 according to the present embodiment is advantageous in that it can prevent unintended user operations, such as accidentally pressing an operation button in a bag. Furthermore, because a child's pressing force, which is inappropriate for a user of suction device 1, cannot easily press button region 15 of panel 10, this is also advantageous in terms of child resistance.

[0024] The main housing 20 has an opening through which the stick-shaped substrate is inserted, and in FIG. 1, the shutter 50 is shown closing the opening. The shutter 50 has a sliding mechanism and is movable along the surface of the outer shell between a first position that closes the opening and a second position that opens the opening. 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 provided in the shutter 50, and the opening and closing of the opening are detected by the magnetic sensor.

[0025] The opening is opened when the user places their finger on the shutter 50 and slides it along the side. As a result of the opening, the user can insert the stick-shaped substrate. After inserting the stick-shaped substrate, the user can press the surface of the panel 10 with their finger and press the operation button to turn on the suction device 1.

[0026] [Examples of the exterior configuration of the panel and main body 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.

[0027] As shown in FIG. 2(a), magnet 11, protrusion 12, magnet 13, and magnet 14 are arranged along the longitudinal direction on the inner surface of panel 10. When panel 10 is attached to main body housing 20, magnet 11 and magnet 14 attract panel 10 to main body housing 20 by their magnetic force (magnetic attraction). This holds panel 10 to main body housing 20. Protrusion 12 presses operation button 22 provided on the surface of main body 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 having magnetic sensor 23 of main body housing 20 detect the magnetic force of the magnetic field applied by magnet 13.

[0028] 2(b), magnet 21, passage hole 25, operation button 22, and magnet 24 are arranged on the outer surface of main body housing 20 along the longitudinal direction from the shutter 50 side. Furthermore, magnetic sensor 23 is arranged on the inner surface of main body housing 20 (more precisely, on a substrate that is substantially zero distance from the inner surface) at a position between operation button 22 and magnet 24 along the longitudinal direction. Magnet 21, operation button 22, magnetic sensor 23, and magnet 24 of main body housing 20 correspond to magnet 11, protrusion 12, magnet 13, and magnet 14 of panel 10, respectively. In other words, when panel 10 is attached to main body housing 20, they are aligned with and face each other.

[0029] Magnets 21 and 24 of main housing 20 are attracted to magnets 11 and 14 of panel 10, respectively, by their magnetic force (magnetic attraction). In other words, magnets 11 and 21, and magnets 14 and 24 attract each other, thereby holding panel 10 in a mountable state to main housing 20. It is preferable that magnets 11 and 14 of panel 10, and magnets 21 and 24 of main housing 20 are made of permanent magnets.

[0030] The operation button 22 is provided on the surface to which the panel 10 is attached. That is, 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.

[0031] The magnetic sensor 23 detects a magnetic force based on the 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, which makes it possible to detect whether the panel 10 is attached to the main body housing 20.

[0032] When the panel 10 is attached to the main housing 20, 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. 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.

[0033] Furthermore, magnetic sensor 23 of main housing 20 is configured not to detect the magnetic fields generated by the two magnets 21 and 24 of main housing 20. Specifically, magnetic sensor 23 is preferably disposed on the inner surface of main housing 20 at a position separated from the two magnets 21 and 24 on the outer surface of main housing 20. This allows the influence of the magnetic fields from these two magnets 21 and 24 on magnetic sensor 23 to be substantially zero.

[0034] Furthermore, it is preferable to configure the main body housing 20 so that the distance between the magnetic sensor 23 and the magnet 24 (or magnet 21) is greater than the distance between the magnet 13 and the magnetic sensor 23 when the panel 10 is attached to the main body housing 20. This allows the magnetic sensor 23 to appropriately consider only the influence of the magnetic field applied from the magnet 13, without considering the influence of the magnetic field of the magnet 24, when detecting the attachment of the panel 10 to the main body housing 20.

[0035] The through hole 25 is an opening aligned with one or more LEDs (Light Emitting Diodes) disposed within the body 30, and allows light from the LEDs to pass through to the display window 60 of the panel 10. This allows the user to view the light from the outer surface of the panel 10.

[0036] [Example of suction device configuration] 3 is a schematic diagram showing an example of the configuration of the inhalation device 1. A stick-type substrate 100 having a flavor-generating substrate, such as a filler containing an aerosol source, which is a source of inhaled components, and a flavor source, is inserted into the inhalation device 1. The aerosol source is not limited to a liquid, but may also be a solid. The inserted stick-type substrate 100 generates a flavor-containing aerosol by being heated from its outer periphery.

[0037] 3, the suction device 1 includes a control unit 90, a power supply unit 91, a sensor unit 92, a notification unit 93, a memory 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.

[0038] The control unit 90 functions as an arithmetic processing unit and a control unit, and controls the overall operation of 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.

[0039] The power supply unit 91 stores electric power and supplies electric power to each component of the suction device 1 under 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.

[0040] 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, or a temperature sensor, 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.

[0041] The sensor unit 92 also detects whether the panel is attached to the main body housing. For example, the sensor unit 92 is configured with a magnetic sensor (e.g., a Hall sensor using a Hall element that detects magnetism using the Hall effect). The sensor unit 92 then detects whether a panel equipped with a magnetic field application unit (e.g., 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.

[0042] The notification unit 93 notifies the user of information. The notification unit 93 is configured by, for example, a display unit made up 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.

[0043] For example, the LED emits light in a predetermined light emission mode to notify the user of operation information of the suction device 1. Specifically, the LED emits light to notify the user of whether the suction device 1 is powered on, the progress of preheating, the suction status (remaining suction time, etc.), and the current operation mode of the suction device 1 (for example, suction mode and / or communication mode, etc.).

[0044] The storage unit 94 stores various information for the operation of the suction device 1. The storage unit 94 is configured, for example, by a non-volatile storage medium such as a flash memory. The storage unit 94 also stores programs such as firmware in addition to computer-executable instructions for operating the suction device 1.

[0045] The communication unit 95 is a communication interface capable of performing communication conforming to any wired or wireless communication standard. For wireless communication, such communication standards may be Wi-Fi (registered trademark) or Bluetooth (registered trademark). For 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.

[0046] The communication unit 95 may activate its 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 that is currently communicating 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).

[0047] 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 through 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 referred to as the longitudinal direction of the suction device 1.

[0048] The holding part 80 has a pressing part and a non-pressing part (neither of which are 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 periphery by the heating part 81 while being pressed.

[0049] Meanwhile, 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.

[0050] The holding part 80 also has the function of defining a flow path for air to be supplied to the stick-shaped substrate 100. An air inlet hole 86, which is the entrance of air to this flow path, is the opening 84. More precisely, the air inlet hole 86 is the gap between the non-pressure part and the stick-shaped 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-shaped substrate 100 to an air outlet hole 87, which is the exit for air from the flow path.

[0051] 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 portion of the substrate portion 101 is contained in the internal space 83, and at least a portion of the mouthpiece portion 102 protrudes from the opening 84. When a user holds the mouthpiece portion 102 protruding from the opening 84 in their mouth and inhales, air flows into the internal space 83 through the air inlet hole 86 and is transported along the dotted arrow to the air outlet hole 87 of the mouthpiece portion 102 via the bottom portion 85, and reaches the user's oral cavity 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.

[0052] The heating unit 81 generates aerosol by heating the aerosol source and atomizing the aerosol source. 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-shaped substrate 100 is heated from the outer periphery, generating aerosol. The heating unit 81 generates heat when power is supplied from the power supply unit 91. For example, the heating unit 81 may be powered 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. The supply of power may be stopped 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 heating unit 81 is an example of a heating unit that generates aerosol by heating a substrate with power from a battery.

[0053] 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.

[0054] 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.

[0055] 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-shaped substrate 100 and heats the substrate 101 of the stick-shaped 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.

[0056] 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.

[0057] [Overview of suction device operation] In the present embodiment, the notification unit 93 of the suction device 1 described above is configured with a plurality of display units arranged in a row to display the status of the device while the device is operating. If an error occurs in the device, the control unit 90 controls the plurality of display units to display the fact that an error has occurred.

[0058] 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.

[0059] Furthermore, the control unit 90 may perform control so that the occurrence of an error is displayed on a plurality of display units in a display mode according to the type of error.

[0060] In this case, the error type may first include a warning-level error type in the system of the device itself. The error type may second include an error type caused by the temperature of the device being outside a predetermined temperature range. The error type may third include an error type that cannot be recovered from by either operating the device itself or the passage of time. The error type may fourth include an error type caused by the removal of a component protecting the device itself.

[0061] In this case, the display mode according to the type of error may first include a display mode in which all or part of the multiple display units flash. The display mode according to the type of error may second include 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. The display mode according to the type of error may third include a display mode in which a first portion and a second portion of the multiple display units are turned on and a third portion of the multiple display units is turned off.

[0062] Here, the plurality of display units are assumed to be N LEDs (N is a natural number).

[0063] Furthermore, a type of warning-level error in the system of the device itself is referred to as a "system error." Although an "alarm error" may be used to refer to a type of warning-level error, it will be unified as a "system error." A type of error caused by the temperature of the device being outside a predetermined temperature range is referred to as a "temperature error." A type of error that cannot be recovered from either by operating the device itself or by the passage of time is referred to as a "permanent failure error." A type of error caused by the removal of a component protecting the device itself is referred to as a "panel error," taking the panel 10 as an example of the component protecting the device itself. However, the component protecting the device itself is not limited to the panel 10, and may be any component.

[0064] Furthermore, a display mode in which all N LEDs are flashed is referred to as a "full flashing mode." A display mode in which some N LEDs are flashed is referred to as a "partial flashing mode." A display mode in which all or some N LEDs are lit for a predetermined period and then turned off for a predetermined period is referred to as an "animation mode." A display mode in which a first portion and a second portion of N LEDs are lit and a third portion of N LEDs is turned off is referred to as a "discontinuous mode."

[0065] As described above, there are system errors, temperature errors, permanent failure errors, and panel errors, and the display modes corresponding to the error types include a full blinking mode, a partial blinking mode, an animation mode, and a skipped mode. Here, as long as the error type and the display mode are associated with each other, any display mode may be used to indicate the occurrence of any error. However, in the following, when a system error occurs, the N LEDs will be displayed in a full blinking mode. When a temperature error occurs, the N LEDs will be displayed in an animation mode. When a permanent failure error occurs, the N LEDs will be displayed in a skipped mode. When a panel error occurs, the N LEDs will be displayed in a partial blinking mode.

[0066] [Example of normal operation of suction device] As examples of normal operations of the suction device 1, the operation of preheating the stick-shaped substrate 100, the operation of inhaling the aerosol, the operation of notifying the user of 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.

[0067] 4(a) to 4(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 preheat the stick-shaped substrate 100. Here, the operation to preheat the stick-shaped substrate 100 is an example of an operation to heat the stick-shaped substrate 100.

[0068] 4(a), all N LEDs 600 are turned off before the stick-shaped substrate 100 is preheated. 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-shaped substrate 100.

[0069] When the suction device 1 starts preheating the stick-shaped substrate 100, 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 the preheating. For example, FIG. 4(b) shows the display when one-quarter of the preheating time has elapsed, with one-quarter of the N LEDs 600 lit. FIG. 4(c) shows the display when two-quarters of the preheating time has elapsed, with two-quarters of the N LEDs 600 lit. FIG. 4(d) shows the display when three-quarters of the preheating time has elapsed, with three-quarters of the N LEDs 600 lit. FIG. 4(e) shows the display when the preheating time has ended, with all N LEDs 600 lit.

[0070] 5(a) to 5(e) are diagrams showing examples of the display of N LEDs 600 visible through the display window 60 when the inhalation device 1 performs an operation of inhaling an aerosol.

[0071] Before the aerosol is inhaled, all 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-shaped substrate 100.

[0072] When the inhalation device 1 starts inhaling the aerosol, the N LEDs 600 turn off the lit LEDs in order from the top, gradually reducing the number of lit LEDs to indicate the decrease in the remaining inhalation time. For example, FIG. 5(b) shows the display when one-quarter of the inhalation period has elapsed, with three-quarters of the N LEDs 600 lit. FIG. 5(c) shows the display when two-quarters of the inhalation period has elapsed, with two-quarters of the N LEDs 600 lit. FIG. 5(d) shows the display when three-quarters of the inhalation period has elapsed, with one-quarter of the N LEDs 600 lit. FIG. 5(e) shows the display when the inhalation period has ended, with all N LEDs 600 lit.

[0073] 6(a) to 6(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 "remaining battery charge").

[0074] 6(a), all N LEDs 600 are lit when the remaining battery charge of the power supply unit 91 is 100%. In this state, the suction device 1 starts using the rechargeable battery.

[0075] When the suction device 1 starts using the rechargeable battery, the N LEDs 600 turn off the lit LEDs from the top, gradually reducing the number of lit LEDs to indicate the decrease in the remaining battery charge. For example, FIG. 6(b) shows the display when the remaining battery charge is 75%, with three-quarters of the N LEDs 600 lit. FIG. 6(c) shows the display when the remaining battery charge is 50%, with two-quarters of the N LEDs 600 lit. FIG. 6(d) shows the display when the remaining battery charge is 25%, with one-quarter of the N LEDs 600 lit. FIG. 6(e) shows the display when the remaining battery charge is such that one stick-shaped substrate 100 can be suctioned, with the lower LED of the N LEDs 600 flashing.

[0076] 7(a) to 7(e) are diagrams showing examples of the display of N LEDs 600 visible through the display window 60 when the suction device 1 is performing an operation to charge the rechargeable battery of the power supply unit 91. FIG.

[0077] 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 charging the rechargeable battery.

[0078] 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 the display when the rechargeable battery is 25% charged, with one-quarter of the N LEDs 600 lit. FIG. 7(c) shows the display when the rechargeable battery is 50% charged, with two-quarters of the N LEDs 600 lit. FIG. 7(d) shows the display when the rechargeable battery is 75% charged, with three-quarters of the N LEDs 600 lit. FIG. 7(e) shows the display when charging of the rechargeable battery is complete, with all N LEDs 600 lit.

[0079] [Example of operation when an error occurs in the suction device] The operation when an error occurs in the suction device 1 will be described using examples of the operation when a system error, a temperature error, a permanent failure error, and a panel error occur. In the following, eight LEDs arranged in a vertical row will be used as an example of the N LEDs 600, and these eight LEDs will be referred to as LED#8, LED#7, ..., LED#1 from top to bottom.

[0080] First, a specific example of the operation when a system error occurs will be described. A system error is an alarm error. In that sense, a system error is an example of a type of warning-level error in the system of the device itself.

[0081] System errors include an error in which the heating unit 81 heats up abnormally and becomes too hot. System errors also include an error in which the resistance value of the heating unit 81 becomes abnormal. Here, an abnormal resistance value of the heating unit 81 means that the resistance value of the heating unit 81 becomes low, that is, a state close to a short circuit, or that the resistance value of the heating unit 81 becomes high, that is, a state close to a break in the wire. System errors also include an error in which the voltage applied to the heating unit 81 becomes abnormal, that is, an error in which the voltage becomes too high or too low.

[0082] If a system error occurs when the 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, an 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 user performs a hardware reset, the system error is cleared.

[0083] 8 is a diagram showing an example of a display in which all eight LEDs 600 are blinking when a system error occurs. In this case, the control unit 90 causes all of the LEDs #1 to #8 to blink at ultra-high speed, as indicated by the cross-hatching within the thick dashed frame. In this specification, "blinking the LEDs at ultra-high speed" means blinking the LEDs at a cycle of 200 milliseconds. However, this is not limiting, and "blinking the LEDs at ultra-high speed" may also mean blinking the LEDs at a cycle other than 200 milliseconds.

[0084] Next, a specific example of the operation when a temperature error occurs will be described. A temperature error is an example of a type of error that occurs when the temperature of the device itself is outside a predetermined temperature range.

[0085] 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, an 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 canceled.

[0086] FIG. 9 is a diagram showing an example of an animation display of eight LEDs 600 when a temperature error occurs.

[0087] 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 dotted hatching within 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 within a thin solid line frame.

[0088] 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 lights up LEDs #1 to #8 normally as shown by the dotted hatching within 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 turns off LEDs #1 to #8 as shown by the white background within the thin solid line frame.

[0089] 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 lights up LEDs #1 to #8 normally as shown by the dotted hatching within 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 turns off LEDs #1 to #8 as shown by the white background within the thin solid line frame.

[0090] After another 3000 milliseconds, the control unit 90 changes the display of LEDs #1 to #8 back to state 601. That is, the control unit 90 causes LEDs #1 to #8 to light up normally as shown by dotted hatching within a thick solid line frame.

[0091] The control unit 90 then repeats three times this display pattern of going from state 601 through states 602 to 606 and then returning to state 601. That is, the control unit 90 displays such a display pattern three times, with each pattern lasting 4600 milliseconds.

[0092] In this specification, "normally lighting an LED" means lighting 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%.

[0093] 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 still open.

[0094] Here, all eight LEDs 600 are turned on for a predetermined period and then turned off for a predetermined period, but this is not limiting. A portion 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 portion of the eight LEDs 600 is turned on, the portion that is turned on may be changed, so that the lit LEDs appear to be moving.

[0095] Next, a specific example of a permanent failure error will be described. A permanent failure error is an error that cannot be recovered from even by a hardware reset. A permanent failure error is also an error that cannot be resolved over time, such as a temperature error. In this sense, a permanent failure error is an example of a type of error that cannot be recovered from either by operating the device itself or by the passage of time.

[0096] When a permanent failure error occurs, power is no longer supplied from the power supply unit 91, and therefore, when power is supplied from an external source while a permanent failure error has occurred, the control unit 90 displays the fact that a permanent failure error has occurred on the eight LEDs 600. For example, when the user connects a powered USB cable to the external connection terminal 70 and the suction device 1 is in a non-charging state, if a permanent failure error has occurred, the control unit 90 displays the fact on the eight LEDs 600.

[0097] 10 is a diagram showing an example of a display in which eight LEDs 600 are displayed in a discontinuous manner when a permanent failure error occurs. In this case, the control unit 90 normally lights up LEDs #1, #4 to #8 as shown by dotted hatching within a thick solid line frame. Meanwhile, the control unit 90 turns off LEDs #2 and #3 as shown by a white background within a thin solid line frame. The control unit 90 displays this information for 5000 milliseconds.

[0098] Here, the "discontinuous display" refers to a display mode in which a first portion and a second portion of the eight LEDs 600 are lit and a third portion of the eight LEDs 600 is turned off. In this case, the first portion, the second portion, and the third portion may be any portion of the eight LEDs 600, but preferably are a portion including an LED at one end, a portion including an LED at the other end, and a portion other than that. For example, in the example of FIG. 10, the control unit 90 preferably turns on the portion including LED #1 and the portion including LED #8 and turns off the remaining portions. This is because turning off LED #1 may lead the user to mistakenly believe that the LEDs are LED #2 through LED #8, and turning off LED #8 may lead the user to mistakenly believe that the LEDs are LED #1 through LED #7.

[0099] Furthermore, the intermittent display mode may be more generalized to a display mode in which three or more portions of the eight LEDs 600 are lit and the remaining portions sandwiched between these portions are turned off. For example, in the example of Fig. 10, the control unit 90 may turn on LEDs #1, #3, #5 to #8 and turn off LEDs #2 and #4. Alternatively, the control unit 90 may turn on LEDs #1 to #4, #6, and #8 and turn off LEDs #5 and #7.

[0100] When the display of Fig. 10 ends, the control unit 90 transitions the suction device 1 to sleep mode. Here, sleep mode refers to a mode in which most functions are unavailable except for functions to detect the opening of the shutter 50, the connection of the USB cable, etc., and the function to monitor the remaining battery level. If the shutter 50 is opened, the button area 15 is pressed, or the panel 10 is removed in sleep mode, the control unit 90 displays Fig. 10 again. Furthermore, if the USB cable is unplugged, the control unit 90 transitions the suction device 1 to shipping mode (power off).

[0101] Next, a specific example of a case where a panel error occurs will be described. A panel error is an error caused by the removal of the panel 10. The panel 10 is an example of a member that protects the device itself, and a panel error is an example of a type of error caused by the removal of a member that protects the device itself.

[0102] When a panel error occurs, the control unit 90 displays that fact on the eight LEDs 600. That is, when the panel 10 is removed, the control unit 90 displays that fact on the eight LEDs 600.

[0103] Furthermore, if an operation to transition to a prohibited state is performed while a panel error has occurred, the control unit 90 displays on the eight LEDs 600 that a panel error has occurred. With the panel 10 detached, only the operation of notifying the remaining battery level and the operation of charging the rechargeable battery are possible. Therefore, if an operation that would transition to another prohibited state is instructed, the control unit 90 displays on the eight LEDs 600 that the panel 10 has been detached.

[0104] Even when the suction device 1 is in sleep mode, the control unit 90 receives the detection of the removal of the panel 10 as an interrupt and displays the removal of the panel 10 on the eight LEDs 600. Then, when the panel 10 is attached, the panel error is cleared.

[0105] 11 is a diagram showing an example of a display in which some of the eight LEDs 600 blink when a panel error occurs. In this case, the control unit 90 causes LED #8 to blink at high speed, as indicated by the diagonal hatching within the thick dashed frame. In this specification, "blinking an LED at high speed" refers to blinking an LED at a 500 millisecond interval. However, this is not limiting, and "blinking an LED at high speed" may also refer to blinking an LED at a interval other than 500 milliseconds.

[0106] Here, the partial blinking mode refers to a display mode in which some of the eight LEDs 600 are blinked. In this case, the "part of the eight LEDs 600" may refer to any number of LEDs among the eight LEDs 600, and may refer to any position of the eight LEDs 600. For example, it is conceivable to blink multiple separated parts in the same manner as in the missing LED mode when a permanent failure error occurs, but the above example shows a case in which LED #8, the topmost LED of the eight LEDs 600, is blinked.

[0107] [Details of operation when an error occurs in the suction device] FIG. 12 is a flowchart showing an example of operation when a system error or a temperature error occurs in the control unit 90 of the suction device 1 in this embodiment.

[0108] As shown in the figure, the control unit 90 first determines whether 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 a system error has occurred (step 902).

[0109] If it is determined in step 902 that a system error has occurred, the control unit 90 causes LEDs #1 to #8 to blink at extremely high speed (step 903). Then, the control unit 90 determines whether a hardware reset has been performed (step 904). If it is determined that a hardware reset has not been performed, the control unit 90 repeats step 904. If it is determined in step 904 that a hardware reset has been performed, the system error is cleared, and the control unit 90 terminates the process.

[0110] On the other hand, if it is determined in step 902 that a system error has not occurred, the control unit 90 determines whether a temperature error has occurred (step 905).

[0111] If it is determined in step 905 that a temperature error has occurred, the control unit 90 turns LEDs #1 to #8 on and off in an animation manner (step 906). For example, the control unit 90 turns LEDs #1 to #8 on, turns them off 400 milliseconds later, turns them on again 200 milliseconds later, turns them off 400 milliseconds later, turns them on again 200 milliseconds later, and turns them off 400 milliseconds later.

[0112] Then, the control unit 90 determines whether an operation to close the shutter 50 has been performed (step 907). If it is determined that an operation to close the shutter 50 has been performed, the control unit 90 ends the process without again executing the turning on and off in the animation mode of step 906. If it is not determined in step 907 that an operation to close the shutter 50 has been performed, the control unit 90 determines whether 3000 milliseconds have elapsed (step 908). If it is not determined that 3000 milliseconds have elapsed, the control unit 90 repeats step 908. If it is determined in step 908 that 3000 milliseconds have elapsed, the control unit 90 determines whether step 906 has been performed three times (step 909). If it is not determined that step 906 has been performed three times, the control unit 90 returns the process to step 906 and again executes the turning on and off in the animation mode of step 906.

[0113] If it is determined in step 909 that step 906 has been executed three times, the control unit 90 determines whether or not an operation to press the button area 15 has been performed (step 910). If it is determined that an operation to press the button area 15 has been performed, the control unit 90 returns the process to step 906 and repeats steps 906 to 909. If it is not determined in step 910 that an operation to press the button area 15 has been performed, the control unit 90 determines whether or not the temperature of the device itself has reached an operable temperature (step 911). If it is not determined that the temperature of the device itself has reached an operable temperature, the control unit 90 returns the process to step 910. If it is determined in step 911 that the temperature of the device itself has reached an operable temperature, the temperature error is canceled, and the control unit 90 ends the process.

[0114] On the other hand, if it is determined in step 905 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 912). If it is determined that an operation to press the button area 15 has been performed, the control unit 90 repeats step 912. If it is determined in step 912 that an operation to press the button area 15 has been performed, the control unit 90 determines whether or not a system error has occurred (step 913).

[0115] If it is determined in step 913 that a system error has occurred, the control unit 90 advances the process to step 903. The process contents of steps 903 and 904 have already been described, so a description thereof will be omitted here.

[0116] On the other hand, if it is determined in step 913 that a system error has not occurred, the control unit 90 determines whether a temperature error has occurred (step 914).

[0117] If it is determined in step 914 that a temperature error has occurred, the control unit 90 advances the process to step 906. The process contents of steps 906 to 911 have already been described, so a description thereof will be omitted here.

[0118] On the other hand, if it is determined in step 914 that a temperature error has not occurred, the control unit 90 ends the process.

[0119] FIG. 13 is a flowchart showing an example of operation when a permanent failure error occurs in the control unit 90 of the suction device 1 in this embodiment.

[0120] As shown in the figure, the control unit 90 first determines whether the USB cable 700 is connected to the external connection terminal 70 (step 921). If it is determined that the USB cable 700 is not connected to the external connection terminal 70, the control unit 90 repeats step 921. If it is determined in step 921 that the USB cable 700 is connected to the external connection terminal 70, the control unit 90 determines whether a permanent failure error has occurred (step 922).

[0121] If it is determined in step 922 that a permanent failure error has occurred, the control unit 90 turns on LEDs #1 to #8 in a skipped pattern (step 923). For example, the control unit 90 turns on LEDs #1, #4 to #8 and turns off LEDs #2 and #3. Then, the control unit 90 transitions the suction device 1 to sleep mode (step 924).

[0122] Thereafter, the control unit 90 determines whether an operation to open the shutter 50 has been performed (step 925). If it is determined that an operation to open the shutter 50 has been performed, the control unit 90 returns the process to step 923 and performs the lighting in the skipped mode of step 923 again.

[0123] If it is determined in step 925 that the operation to open the shutter 50 has not been performed, the control unit 90 determines whether or not an operation to press the button area 15 has been performed (step 926). If it is determined that an operation to press the button area 15 has been performed, the control unit 90 returns the process to step 923 and performs the lighting in the skipped pattern of step 923 again.

[0124] If it is determined in step 926 that the button area 15 has not been pressed, the control unit 90 determines whether the panel 10 has been removed (step 927). If it is determined that the panel 10 has been removed, the control unit 90 returns the process to step 923 and performs the lighting in the skipped pattern of step 923 again.

[0125] If it is not determined in step 927 that panel 10 has been removed, control unit 90 determines whether USB cable 700 has been unplugged from external connection terminal 70 (step 928). Also, if it is not determined in step 922 that a permanent failure error has occurred, control unit 90 performs normal operations such as charging the rechargeable battery of power supply unit 91, and then determines whether USB cable 700 has been unplugged from external connection terminal 70 (step 928).

[0126] If it is not determined in step 928 that the USB cable 700 has been removed from the external connection terminal 70, the control unit 90 repeats step 928. If it is determined in step 928 that the USB cable 700 has been removed from the external connection terminal 70, the control unit 90 ends the process. That is, the control unit 90 transitions the suction device 1 to the shipping mode.

[0127] FIG. 14 is a flowchart showing an example of operation when a panel error occurs in the control unit 90 of the suction device 1 in this embodiment.

[0128] As shown in the figure, the control unit 90 first determines whether the panel 10 has been removed (step 941). If it is determined that the panel 10 has not been removed, the control unit 90 repeats step 941. If it is determined in step 941 that the panel 10 has been removed, the control unit 90 causes LED #8 to flash at high speed (step 942).

[0129] Next, the control unit 90 determines whether an operation to instruct some kind of operation has been performed (step 943). If it is determined that an operation to instruct some kind of operation has not been performed, the control unit 90 repeats step 943. If it is determined in step 943 that an operation to instruct some kind of operation has been performed, the control unit 90 determines whether the operation is prohibited from being performed without the panel 10 (step 944). If it is determined that the operation is prohibited from being performed without the panel 10, the control unit 90 determines whether the panel 10 has been removed (step 945). If it is determined that the panel 10 has been removed, the control unit 90 causes LED #8 to flash at high speed (step 946).

[0130] If it is not determined in step 944 that the instructed operation is an operation that is prohibited from being performed without the panel 10, or if it is not determined in step 945 that the panel 10 is removed, the control unit 90 executes the instructed operation (step 947).

[0131] Thereafter, the control unit 90 determines whether the panel 10 has been attached (step 948). If it is determined that the panel 10 has not been attached, the control unit 90 returns the process to step 943. If it is determined in step 948 that the panel 10 has been attached, the control unit 90 ends the process.

[0132] [Variations] While the above description has been given of the application of the present invention to a heated tobacco product, the present invention is not limited to this. The present invention can be applied to various inhalation devices for inhaling aerosols, such as electronic cigarettes and nebulizers. Furthermore, the inhaled components generated may include gases such as invisible vapors in addition to aerosols. Furthermore, the present invention may be applied to a display device connected to a device other than an inhalation device and displaying information about the device. In this case, the N LEDs 600 are an example of a plurality of display units arranged in a row to display the status of the device while it is operating. Furthermore, the control unit 90 is an example of 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.

[0133] [Advantages of this embodiment] In the suction device 1 of this embodiment, when the device is operating, the status of the device itself is displayed on multiple display units arranged in a row, and when an error occurs in the device, the fact that an error has occurred is displayed on multiple display units. This makes it possible in this embodiment to clearly display the status of the device itself when it is operating and the fact that an error has occurred when an error occurs in the device.
