That is, when the outer panel 102 is attached to the inner panel 202 , the distance between the magnetic sensor 23 A of the inner panel 202 and the magnet 13 A of the outer panel 102 is minimum.
- the magnetic sensor 23 A of the inner panel 202 is configured not to detect a magnetic field generated by each of the two magnets 21 A and 24 of the inner panel 202 .
- the magnetic sensor 23 A is arranged at a position separated from the two magnets 21 A and 24 on the outer surface of the inner panel 202 . This can set the influence of the magnetic fields from the two magnets 21 A and 24 on the magnetic sensor 23 A to approximately zero.
- the distance between the magnetic sensor 23 A and the magnet 24 (or the magnet 21 A) of the inner panel 202 can be set to be larger than the distance between the magnetic sensor 23 A and the magnet 13 A in the state in which the outer panel 102 is attached to the inner panel 202 .
- the outer panel 102 can be configured so that data measured by the magnetic sensor 23 A changes depending on the type of the outer panel 102 when the outer panel 102 is attached to the inner panel 202 . More specifically, the outer panel 102 is configured so that the magnitude of the magnetic force concerning the magnet 13 A of the magnetic field application unit, which is detected by the magnetic sensor 23 A of the inner panel 202 , changes depending on the type of the panel.
- the outer panel 102 can be configured so that the distance between the magnet 13 A as the magnetic field application unit and its facing magnetic sensor 23 A changes depending on the type of the outer panel in the state in which the outer panel 102 is attached to the inner panel 202 . That is, the shape of the curved surface may be adjusted for each type of outer panel so that the height of the inner surface of the outer panel 102 changes depending on the type. Note that those skilled in the art generally understand that the magnitude of the magnetic force changes depending on the distance from the magnet (more specifically, the magnitude of the magnetic force is inversely proportional to the square of the distance). Thus, it is possible to use the common magnet 13 A in any type of the outer panel 102 , which is advantageous in manufacturing.
- the position of the magnet 13 A may be shifted so as to change depending on the type of the outer panel along the inner surface of the facing outer panel 102 . This can change the distance between the magnet 13 A and the magnetic sensor 23 A in accordance with the type of the outer panel. That is, the magnitude of the magnetic force detected by the magnetic sensor 23 A can be changed in accordance with the type of the panel.
- the outer panel 102 can be configured so that the type of the magnet 13 A as the magnetic field application unit changes depending on the type of the outer panel.
- the magnet 13 A is formed by, for example, a permanent magnet. More specifically, one of a Ferrite magnet, an Al—Ni—Co magnet, a cobalt magnet, a Neodymium magnet, and the like is selected in accordance with the type of the outer panel. This can change the magnitude of the magnetic force detected by the magnetic sensor 23 A in accordance with the type of the outer panel.

- a magnetic body 13 B is arranged above the display window 103 , the projection 12 is arranged below the display window 103 , and a magnet 15 is arranged below the projection 12 .
- the magnetic body 13 B includes a circular base portion 11 B, and a leg portion 12 B that linearly extends from the base portion 11 B approximately in the longitudinal direction.
- the magnetic body 13 B is made of a material that becomes magnetized, when a magnetic field is applied from the outside, by the action of the magnetic field, and applies a magnetic field.
- the magnetic body 13 B is formed as a magnetic field application unit for a magnetic sensor 23 B (to be described later) of the inner panel 202 .
- the magnetic body 13 B can be made of, for example, a metal. More specifically, the magnetic body 13 B can be made of a paramagnetic material or a ferromagnetic material as a non-permanent magnet. “Ferromagnetic” indicates the property of a material that becomes strongly magnetized, when a magnetic field is applied from the outside, in the same direction as that of the magnetic field, and is still magnetized even if the magnetic field from the outside is set to zero. Examples of the ferromagnetic material are iron, cobalt, and nickel.
- paramagnetic indicates the property of a material that becomes weakly magnetized, when a magnetic field is applied from the outside, in the same direction as that of the magnetic field, and is not magnetized when the magnetic field from the outside is set to zero.
- An example of the paramagnetic material is aluminum.
- the magnetic body 13 B is formed as an acted upon unit that changes in a state (that is, is magnetized) in accordance with the action of a magnetic field applied from the outside.
- the magnetic body 13 B is formed as a magnetic field application unit that applies a magnetic field to the inner panel 202 . More specifically, if the outer panel 102 is attached to the inner panel 202 , the magnetic body 13 B functions as an acted upon unit that a magnet 21 B of the inner panel 202 acts upon. As a result, the magnetic body 13 B is magnetized, and functions as a magnetic field application unit for the magnet 21 B and the magnetic sensor 23 B of the inner panel 202 .
- the outer panel 102 can be attracted to and held by the inner panel 202 by a magnetic force based on a magnetic field generated and applied by the magnetic body 13 B (particularly, the base portion 11 B). Furthermore, with respect to a magnetic field generated and applied by the magnetic body 13 B (particularly, the leg portion 12 B), the magnetic sensor 23 B of the inner panel 202 can be made to detect the state of the leg portion 12 B (that is, a magnetic force based on the magnetic field from the leg portion 12 B). This can cause the power source unit 101 to detect the attachment of the outer panel 102 .

- the magnetic sensor 23 B is arranged on a side of the display window 25 on the inner surface of the inner panel 202 (more correctly, on a substrate with an approximately zero distance to the inner surface).
- the magnetic sensor 23 B forms a magnetic force detection region 26 B indicated by a broken line on the outer surface of the inner panel 202 .
- the magnet 21 B, the magnetic sensor 23 B, the display window 25 , the action button B, and the magnet 27 on the side of the inner panel 202 correspond to the base portion 11 B of the magnetic body 13 B, the leg portion 12 B of the magnetic body 13 B, the display window 103 , the projection 12 , and the magnet 15 on the side of the outer panel 102 , respectively. That is, when the outer panel 102 is attached to the inner panel 202 , the panels are aligned with respect to the respective components so that they face each other.

- the outer panel 102 and the inner panel 202 are arranged so that the base portion 11 B of the magnetic body 13 B of the outer panel 102 is aligned with the magnet 21 B of the inner panel 202 and the leg portion 12 B of the magnetic body 13 B of the outer panel 102 is aligned with the magnetic sensor 23 B of the inner panel 202 .
- the magnetic sensor 23 B faces the leg portion 12 B of the magnetic body 13 B via the inner surface of the inner panel 202 , and thus the distance between the magnetic sensor 23 B and the leg portion 12 B of the magnetic body 13 B is minimum.
- the magnet 21 B of the inner panel 202 is formed as an acting unit that generates a magnetic field.
- a magnetic force based on the magnetic field acts to magnetize the magnetic body 13 B in the outer panel 102 , thereby attracting the base portion 11 B of the magnetic body. That is, the magnet 21 B and the base portion 11 B of the magnetic body 13 B attract each other by the magnetic attraction force, and thus the inner panel 202 can hold the outer panel 102 .
- the magnetic sensor 23 B detects the magnetic force of the leg portion 12 B of the magnetic body 13 B magnetized in the outer panel 102 .
- the magnetic sensor 23 B can be a Hall sensor formed using a Hall element. This can detect the attachment of the outer panel 102 to the inner panel 202 .
- the magnetic sensor 23 B of the inner panel 202 is configured not to detect a magnetic field generated by each of the two magnets 21 B and 27 of the inner panel 202 .
- the magnetic sensor 23 B is arranged at a position separated from the two magnets 21 B and 27 on the outer surface of the inner panel 202 . This can set the influence of the magnetic fields from the two magnets 21 B and 27 on the magnetic sensor 23 B to approximately zero.
- the distance between the magnetic sensor 23 B and the magnet 21 B (or the magnet 27 ) of the inner panel 202 can be set to be larger than the distance between the magnetic sensor 23 B and the magnetic body 13 B in the state in which the outer panel 102 is attached to the inner panel 202 .
- the outer panel 102 can be configured so that data measured by the magnetic sensor 23 B changes depending on the type of the outer panel 102 when the outer panel 102 is attached to the inner panel 202 .

- the outer panel 102 is configured so that the distance between the leg portion 12 B of the magnetic body 13 B and its facing magnetic sensor 23 B changes depending on the type of the outer panel in the state in which the outer panel 102 is attached to the inner panel 202 . That is, the shape of the curved surface may be adjusted for each type of panel so that the height of the inner surface of the outer panel 102 changes depending on the type.
- the common magnetic body 13 B is used in any type of the outer panel 102 , which is advantageous in manufacturing.
- the position of the magnetic body 13 B may be shifted so as to change depending on the type of the panel along the inner surface of the facing outer panel 102 . This can change the distance between the magnetic body 13 B and the magnetic sensor 23 B in accordance with the type of the panel. That is, the magnitude of the magnetic force detected by the magnetic sensor 23 B can be changed in accordance with the type of the panel.

If this condition is satisfied, the control unit 120 transitions to the sleep mode 61 in step S 204 .

At this time, the unlock operation may be disabled. Note that in this case, the control unit 120 may transition to the sleep mode 61 instead of returning to step S 201 .

If the aerosol generation end condition is satisfied, the process advances to step S 304 , and the control unit 120 stops the power supply to the heater H.

- step S 301 If it is determined in step S 301 that the outer panel 102 is detached from the power source unit 101 , the control unit 120 makes, in step S 306 , a notification by the display D and/or the vibration generation unit V, and prohibits, in step S 307 , power supply to the heater H as the function restriction.
- step S 308 the control unit 120 may determine whether the outer panel 102 is attached to the power source unit 101 . While the outer panel 102 is not attached to the power source unit 101 , the determination processing in step S 308 can be repeated for a predetermined time. However, if the predetermined time elapses (YES in step S 310 ), the control unit 120 transitions to the active mode 62 in step S 311 .

- the control unit 120 can acquire the residual battery amount based on an output from the management circuit.
- step S 402 the control unit 120 determines whether the residual battery amount exceeds a predetermined threshold.
- the predetermined threshold is a threshold for determining whether to permit the operation in the pairing mode 66 with respect to the residual battery amount. More specifically, the predetermined threshold can be set as the predetermined lower limit value of the residual battery amount by assuming that electric power shortage does not occur during pairing processing. If the residual battery amount is equal to or smaller than the predetermined threshold, the power source unit 101 cannot operate in the pairing mode 66 . Therefore, in step S 403 , the control unit 120 makes a notification by the display D and/or the vibration generation unit V, and then advances to step S 413 to return to the sleep mode 61 .
- step S 404 the control unit 120 displays the residual battery amount on the display D.
- step S 405 the control unit 120 determines whether the outer panel 102 is attached to the power source unit 101 . If it is determined that the outer panel 102 is detached from the power source unit 101 , the control unit 120 makes, in step S 406 , a notification by the display D and/or the vibration generation unit V, and advances to step S 413 to return to the sleep mode 61 . As described above, in this embodiment, if the detachment of the outer panel 102 is detected in the pairing mode 66 , the control unit 120 prohibits execution of pairing as the function restriction.
- the control unit 120 leaves the pairing mode 66 , and transitions to the sleep mode 61 . If it is determined that the outer panel 102 is detached from the power source unit 101 in the pairing mode 66 , the pairing operation performed so far may be canceled.
- step S 405 If it is determined in step S 405 that the outer panel 102 is attached to the power source unit 101 , the control unit 120 executes, in step S 407 , pairing complying with Bluetooth® with an external communication device.
- step S 408 the control unit 120 determines whether the pairing processing has succeeded or failed. For example, if a time-out occurs before the completion of the pairing processing, an error is notified from the external communication device, or a cancel operation of the pairing processing is detected, the control unit 120 can determine a pairing failure. Furthermore, if it is detected that the outer panel 102 is detached from the power source unit 101 during the pairing processing, the control unit 120 interrupts the pairing processing, and determines a pairing failure.
- step S 408 the control unit 120 makes, in step S 409 , a notification that the pairing processing has succeeded, by the display D and/or the vibration generation unit V.

- the pairing cancellation condition can be, for example, a condition that the slider 105 is operated to be set in the shutter open state, a condition that the action button B is pressed, a condition that a pairing cancellation request is received from the external communication device, a condition that a non-operation period exceeds a predetermined time, or the like. If the pairing cancellation condition is satisfied, the control unit 120 performs, in step S 411 , processing of disconnecting Bluetooth connection from the external communication device, and transitions to the sleep mode 61 in step S 413 .

- the control unit 120 displays the residual battery amount on the display D.
- step S 503 the control unit 120 determines whether an unlock setting operation is performed.
- the unlock setting operation can be, for example, a combination of an operation of opening/closing the slider 105 and a predetermined number of times of continuous pressing of the action button B. If no unlock setting operation is detected, the control unit 120 determines in step S 504 whether charging has ended. If, for example, the external power supply (charger) is detached from the connection OF 128 or the battery 132 is set in the full charge state, it can be determined that charging has ended. If it is determined that charging has not ended, the process returns to step S 501 . If it is determined that charging has ended, the control unit 120 transitions to the sleep mode 61 in step S 507 .
- step S 505 the control unit 120 determines in step S 505 whether the outer panel 102 is attached to the power source unit 101 .

If the outer panel 102 is not attached to the power source unit 101 , the control unit 120 does not transition to the unlock setting mode 65 , and the process advances to step S 504 . That is, even if the unlock setting operation is detected in the state in which the outer panel 102 is detached, the control unit 120 does not transition to the unlock setting mode 65 as the function restriction. The unlock setting operation may be disabled. Note that if the outer panel 102 is not attached to the power source unit 101 , a notification of it may be made.
- the battery 132 is continuously charged.
- transition to the unlock setting mode 65 in the state in which the outer panel 102 is detached is not permitted.

- step S 602 If it is determined in step S 602 that the outer panel 102 is not attached to the power source unit 101 , the control unit 120 discards, in step S 604 , data of the unlock operation pattern input in step S 601 .

- <Arrangement of Inhaler>
-
FIGS. 1A and 1B show an example of the outer appearance of aninhaler 100 according to an embodiment. Theinhaler 100 provides, to a user via astick 110, flavored aerosol, a gas containing aerosol and a flavor material, aerosol, or aerosol containing a flavor material in accordance with an operation of requesting aerosol (to be also referred to as an “aerosol generation request” hereinafter) such as an inhalation operation by the user. Therefore, theinhaler 100 may be understood as an aerosol generation device. - The
inhaler 100 can be formed by apower source unit 101 and thestick 110. Thestick 110 is, for example, a base material including an aerosol source and a flavor source. The aerosol source can be, for example, a liquid such as a polyhydric alcohol such as glycerin or propylene glycol. Alternatively, the aerosol source may contain a drug. The aerosol source may be a liquid, a solid, or a mixture of a liquid and a solid. A vapor source such as water may be used in place of the aerosol source. The flavor source can be, for example, a formed body obtained by forming a tobacco material. Alternatively, the flavor source may be formed by a plant (for example, mint, herb, Chinese medicine, coffee beans, or the like) other than tobacco. A fragrance such as menthol may be added to the flavor source. The flavor source may be added to the aerosol source. - The
power source unit 101 has a substantially rectangular parallelopiped shape with round corners that is elongated in the vertical direction of the sheet surface of each ofFIGS. 1A and 1B , and can be formed in a size which the user can grasp with one hand. Thepower source unit 101 can include anouter panel 102, an action button B, and aslider 105. - The
outer panel 102 is a flexible panel member that covers at least part of the front surface of thepower source unit 101. Theouter panel 102 is an exterior member of thepower source unit 101, that is detachable for replacement, and may be understood as a decorative panel. For example, a plurality of outer panels different in color and pattern are prepared, and the user can replace the outer panel by a preferred outer panel. Theouter panel 102 may be understood as a heat-insulating panel that insulates heat generated in thepower source unit 101, or as a protection panel that protects the inside of thepower source unit 101 from an impact or compression at the time of falling. - A
display window 103 is formed in theouter panel 102. Thedisplay window 103 can be a band-like window extending along the longitudinal direction (the vertical direction of the sheet surface) in substantially the center of theouter panel 102. Thepower source unit 101 includes a display D (display unit) (seeFIG. 2 ). The display D can include, for example, one or more LEDs (Light-Emitting Diodes). Light emitted by the LED passes through thedisplay window 103. The display D can display, for example, a residual battery amount by a bar graph. - The action button B is an operation button formed by a physical push button. The action button B is covered with the
outer panel 102. However, since theouter panel 102 is flexible, the user can operate the action button B via theouter panel 102. When the user presses the action button B via theouter panel 102, a corresponding signal is transmitted to a control unit (to be described later). Note that this embodiment will describe, as an example, a case where the action button B formed by a physical button is covered with theouter panel 102 but another arrangement may be adopted as long as a user operation can be accepted. For example, instead of the action button B, another arbitrary type of input device such as a switch or a touch sensing surface exposed from theouter panel 102 may be provided. - Note that the
outer panel 102 may be imparted with such rigidity that the user needs to push theouter panel 102 using a plurality of fingers to operate the action button B via theouter panel 102. This can prevent, for example, the action button B from being erroneously pressed in a bag or an unintended erroneous operation by the user. This is also advantageous in terms of prevention of child mischief (child resistance). - The
slider 105 is a cover member (shutter) slidably disposed on the upper surface of thepower source unit 101 along adirection 105 a indicated by an arrow. Theslider 105 is configured to open/close an opening into which thestick 110 is inserted.FIG. 1A shows a state in which anopening 106 is covered with theslider 105. This state will also be referred to as a “shutter closed state” hereinafter.FIG. 1B shows a state in which theopening 106 is exposed by sliding theslider 105 to the near side. This state will also be referred to as a “shutter open state” hereinafter. - When inhaling aerosol using the
inhaler 100, the user operates theslider 105 to the shutter open state. After that, the user inserts thestick 110 into theopening 106. The insertedstick 110 is held by atubular holding portion 107 communicating with theopening 106. A section perpendicular to the longitudinal direction of the holdingportion 107 can be, for example, circular, elliptical, or polygonal, and the sectional area of the section gradually reduces toward the bottom surface. With this arrangement, the inner surface of the holdingportion 107 pushes the outer surface of thestick 110 inserted into the holdingportion 107, thereby making it possible to prevent a fall of thestick 110 by the frictional force. After that, the user can perform an unlock operation using the action button B. If the unlock operation is performed, thepower source unit 101 is unlocked to start heating thestick 110, thereby setting an inhalation enable state. When the inhalation enable state is thus set, the user can hold, in the mouth, a mouthpiece portion formed at the distal end of thestick 110 and inhale flavored aerosol. After the end of the inhalation of the aerosol, the user performs an operation of pulling out thestick 110 from the holdingportion 107, and closing the slider 105 (shutter closed state). -
FIG. 2 is a view showing the internal arrangement of theinhaler 100. Note thatFIG. 2 does not illustrate theouter panel 102. As described above, thepower source unit 101 includes the holdingportion 107 that communicates with theopening 106 and holds thestick 110. Furthermore, thepower source unit 101 can include a heater H, an electrical component E, and auser interface 116. Theuser interface 116 may be understood to be included in the electrical component E. The heater H forms a heating unit that heats thestick 110. The heater H can include, for example, a resistive heat generating component that generates aerosol by heating an aerosol source included in thestick 110. As a resistive heat generating material of the resistive heat generating component, for example, a mixture of one or more of copper, a nickel alloy, a chromium alloy, stainless steel, and platinum rhodium can be used. The heater H is arranged to cover the periphery of the holdingportion 107, and generates heat by electric power supplied from the electrical component E. The heat of the heater H is transmitted to thestick 110 via the holdingportion 107, thereby heating thestick 110. When thestick 110 is heated, thestick 110 generates aerosol. Theuser interface 116 can include the action button B, the display D, and a vibration generation unit V. The vibration generation unit V can be formed by a vibration motor (vibrator) for vibrating the housing of thepower source unit 101. By vibrating the housing by the vibration motor, it is possible to notify the user, who holds thepower source unit 101, of the state. - If the user holds the mouthpiece portion at the distal end of the
stick 110 in the mouth and performs an inhalation operation, air flows into the stick through an opening (not shown), as exemplified by a broken arrow A. When the heater H heats thestick 110, the vaporized and/or aerosolized aerosol source is transported toward the mouthpiece portion by air. In the process in which the aerosol source is transported toward the mouthpiece portion, the vaporized and/or aerosolized aerosol source is cooled to form fine liquid droplets, thereby promoting aerosolization. In the arrangement in which the flavor source is also included in thestick 110, a flavor material generated from the flavor source is added to the aerosol, and the resultant flavored aerosol is transported to the mouthpiece portion, and inhaled by the user's mouth. - Note that the example in which the heater H is incorporated in the
power source unit 101 has been described above. An arrangement in which a heater (atomizer), an aerosol source, and a flavor source are provided in the form of a cartridge, instead of thestick 110, may be adopted. - Arrangement examples for attachment of the
outer panel 102 to thepower source unit 101 will be described with reference toFIGS. 3A and 3B andFIGS. 4A and 4B . -
FIG. 3A is a view showing the inner surface of theouter panel 102.FIG. 3B is a view showing a portion exposed to the front surface of thepower source unit 101 in a state in which theouter panel 102 is detached. Thepower source unit 101 includes ahousing 101 a that accommodates a power supply and an electric component (including a control unit to be described later), and aninner panel 202. Referring toFIG. 3B , theinner panel 202 is arranged around the action button B to expose the action button B, and is arranged to cover the front surface of thehousing 101 a. In a state in which theouter panel 102 is attached to thepower source unit 101, the inner surface of theouter panel 102 and the outer surface of theinner panel 202 face each other. - As shown in
FIG. 3A , on the inner surface of theouter panel 102, amagnet 11 is arranged above thedisplay window 103, aprojection 12 is arranged below thedisplay window 103, andmagnets projection 12. If theouter panel 102 is brought closer to theinner panel 202 to be attached to theinner panel 202, the magnetic force (magnetic attraction force) of themagnets outer panel 102 to theinner panel 202. This causes theouter panel 102 to be held by theinner panel 202. When theouter panel 102 is held by theinner panel 202, theprojection 12 is at such position facing the action button B that the action button B can be pressed. Amagnetic sensor 23A is arranged on the rear surface of theinner panel 202. Themagnet 13A is formed as a magnetic field application unit for themagnetic sensor 23A. When themagnetic sensor 23A detects a magnetic force by a magnetic field applied from themagnet 13A, it is possible to detect the attachment of theouter panel 102. - As shown in
FIG. 3B , on the outer surface of theinner panel 202, adisplay window 25 is formed above the action button B, amagnet 21A is arranged above thedisplay window 25, and amagnet 24 is arranged below the action button B. Furthermore, themagnetic sensor 23A is arranged at a position between the action button B and themagnet 24 on the inner surface (more correctly, on a substrate with an approximately zero distance to the inner surface) of theinner panel 202. Themagnetic sensor 23A forms a magneticforce detection region 26A indicated by a broken line on the outer surface of theinner panel 202. Themagnet 21A, thedisplay window 25, the action button B, themagnetic sensor 23A, and themagnet 24 on the side of theinner panel 202 correspond to themagnet 11, thedisplay window 103, theprojection 12, themagnet 13A, and themagnet 14 on the side of theouter panel 102, respectively. That is, when theouter panel 102 is attached to theinner panel 202, the panels are aligned with respect to the respective components so that they face each other. - The
magnets inner panel 202 can be attracted to themagnets outer panel 102 by the magnetic forces (magnetic attraction forces), respectively. That is, when themagnets magnets inner panel 202 can hold theouter panel 102. Note that each of themagnets outer panel 102 and themagnets inner panel 202 can be formed by a permanent magnet. - The action button B arranged in the central portion of the
inner panel 202 is covered with theouter panel 102 when theouter panel 102 is attached to theinner panel 202. The user can press the action button B via theprojection 12 of theouter panel 102 by pressing a portion around the central portion of theouter panel 102. This can switch, for example, power-on/off of theinhaler 100. - The
magnetic sensor 23A detects a magnetic force based on a magnetic field applied from themagnet 13A in theouter panel 102. For example, themagnetic sensor 23A can be a Hall sensor formed using a Hall element. This can detect the attachment of theouter panel 102 to theinner panel 202. In the state in which theouter panel 102 is attached to theinner panel 202, light from the display D is transmitted through thedisplay window 25 of theinner panel 202 and thedisplay window 103 of theouter panel 102. - The
magnetic sensor 23A of theinner panel 202 is arranged to face themagnet 13A of theouter panel 102 via the inner surface of theinner panel 202 in the state in which theouter panel 102 is attached to theinner panel 202. That is, when theouter panel 102 is attached to theinner panel 202, the distance between themagnetic sensor 23A of theinner panel 202 and themagnet 13A of theouter panel 102 is minimum. - Furthermore, the
magnetic sensor 23A of theinner panel 202 is configured not to detect a magnetic field generated by each of the twomagnets inner panel 202. For example, on the inner surface of theinner panel 202, themagnetic sensor 23A is arranged at a position separated from the twomagnets inner panel 202. This can set the influence of the magnetic fields from the twomagnets magnetic sensor 23A to approximately zero. - The distance between the
magnetic sensor 23A and the magnet 24 (or themagnet 21A) of theinner panel 202 can be set to be larger than the distance between themagnetic sensor 23A and themagnet 13A in the state in which theouter panel 102 is attached to theinner panel 202. Thus, when detecting the attachment of theouter panel 102 to theinner panel 202, it is possible to appropriately consider only the influence of the magnetic field applied from themagnet 13A on themagnetic sensor 23A without considering the influence of the magnetic field of themagnet 24. - In an example, the
outer panel 102 can be configured so that data measured by themagnetic sensor 23A changes depending on the type of theouter panel 102 when theouter panel 102 is attached to theinner panel 202. More specifically, theouter panel 102 is configured so that the magnitude of the magnetic force concerning themagnet 13A of the magnetic field application unit, which is detected by themagnetic sensor 23A of theinner panel 202, changes depending on the type of the panel. - For example, the
outer panel 102 can be configured so that the distance between themagnet 13A as the magnetic field application unit and its facingmagnetic sensor 23A changes depending on the type of the outer panel in the state in which theouter panel 102 is attached to theinner panel 202. That is, the shape of the curved surface may be adjusted for each type of outer panel so that the height of the inner surface of theouter panel 102 changes depending on the type. Note that those skilled in the art generally understand that the magnitude of the magnetic force changes depending on the distance from the magnet (more specifically, the magnitude of the magnetic force is inversely proportional to the square of the distance). Thus, it is possible to use thecommon magnet 13A in any type of theouter panel 102, which is advantageous in manufacturing. - In another example, the position of the
magnet 13A may be shifted so as to change depending on the type of the outer panel along the inner surface of the facingouter panel 102. This can change the distance between themagnet 13A and themagnetic sensor 23A in accordance with the type of the outer panel. That is, the magnitude of the magnetic force detected by themagnetic sensor 23A can be changed in accordance with the type of the panel. - In still another example, the
outer panel 102 can be configured so that the type of themagnet 13A as the magnetic field application unit changes depending on the type of the outer panel. Themagnet 13A is formed by, for example, a permanent magnet. More specifically, one of a Ferrite magnet, an Al—Ni—Co magnet, a cobalt magnet, a Neodymium magnet, and the like is selected in accordance with the type of the outer panel. This can change the magnitude of the magnetic force detected by themagnetic sensor 23A in accordance with the type of the outer panel. -
FIGS. 4A and 4B show an arrangement example different from that shown inFIGS. 3A and 3B .FIG. 4A is a view showing the inner surface of theouter panel 102.FIG. 4B is a view showing a portion exposed to the front surface of thepower source unit 101 in a state in which theouter panel 102 is detached.FIG. 4B is a view of the outer appearance of the outer surface of theinner panel 202. In the state in which theouter panel 102 is attached to thepower source unit 101, the inner surface of theouter panel 102 and the outer surface of theinner panel 202 face each other. - As shown in
FIG. 4A , on the inner surface of theouter panel 102, amagnetic body 13B is arranged above thedisplay window 103, theprojection 12 is arranged below thedisplay window 103, and amagnet 15 is arranged below theprojection 12. Furthermore, themagnetic body 13B includes acircular base portion 11B, and aleg portion 12B that linearly extends from thebase portion 11B approximately in the longitudinal direction. Themagnetic body 13B is made of a material that becomes magnetized, when a magnetic field is applied from the outside, by the action of the magnetic field, and applies a magnetic field. Themagnetic body 13B is formed as a magnetic field application unit for amagnetic sensor 23B (to be described later) of theinner panel 202. Themagnetic body 13B can be made of, for example, a metal. More specifically, themagnetic body 13B can be made of a paramagnetic material or a ferromagnetic material as a non-permanent magnet. “Ferromagnetic” indicates the property of a material that becomes strongly magnetized, when a magnetic field is applied from the outside, in the same direction as that of the magnetic field, and is still magnetized even if the magnetic field from the outside is set to zero. Examples of the ferromagnetic material are iron, cobalt, and nickel. In addition, “paramagnetic” indicates the property of a material that becomes weakly magnetized, when a magnetic field is applied from the outside, in the same direction as that of the magnetic field, and is not magnetized when the magnetic field from the outside is set to zero. An example of the paramagnetic material is aluminum. - The
magnetic body 13B is formed as an acted upon unit that changes in a state (that is, is magnetized) in accordance with the action of a magnetic field applied from the outside. In addition, themagnetic body 13B is formed as a magnetic field application unit that applies a magnetic field to theinner panel 202. More specifically, if theouter panel 102 is attached to theinner panel 202, themagnetic body 13B functions as an acted upon unit that amagnet 21B of theinner panel 202 acts upon. As a result, themagnetic body 13B is magnetized, and functions as a magnetic field application unit for themagnet 21B and themagnetic sensor 23B of theinner panel 202. More specifically, theouter panel 102 can be attracted to and held by theinner panel 202 by a magnetic force based on a magnetic field generated and applied by themagnetic body 13B (particularly, thebase portion 11B). Furthermore, with respect to a magnetic field generated and applied by themagnetic body 13B (particularly, theleg portion 12B), themagnetic sensor 23B of theinner panel 202 can be made to detect the state of theleg portion 12B (that is, a magnetic force based on the magnetic field from theleg portion 12B). This can cause thepower source unit 101 to detect the attachment of theouter panel 102. - As shown in
FIG. 4B , on the outer surface of theinner panel 202, thedisplay window 25 is formed above the action button B, themagnet 21B is arranged above thedisplay window 25, and amagnet 27 is arranged below the action button B. Furthermore, themagnetic sensor 23B is arranged on a side of thedisplay window 25 on the inner surface of the inner panel 202 (more correctly, on a substrate with an approximately zero distance to the inner surface). Themagnetic sensor 23B forms a magneticforce detection region 26B indicated by a broken line on the outer surface of theinner panel 202. Themagnet 21B, themagnetic sensor 23B, thedisplay window 25, the action button B, and themagnet 27 on the side of theinner panel 202 correspond to thebase portion 11B of themagnetic body 13B, theleg portion 12B of themagnetic body 13B, thedisplay window 103, theprojection 12, and themagnet 15 on the side of theouter panel 102, respectively. That is, when theouter panel 102 is attached to theinner panel 202, the panels are aligned with respect to the respective components so that they face each other. When theouter panel 102 is attached to theinner panel 202, they are arranged so that themagnetic body 13B of theouter panel 102 is aligned with both themagnet 21B and themagnetic sensor 23B of theinner panel 202. More specifically, theouter panel 102 and theinner panel 202 are arranged so that thebase portion 11B of themagnetic body 13B of theouter panel 102 is aligned with themagnet 21B of theinner panel 202 and theleg portion 12B of themagnetic body 13B of theouter panel 102 is aligned with themagnetic sensor 23B of theinner panel 202. In particular, when theouter panel 102 is attached to theinner panel 202, themagnetic sensor 23B faces theleg portion 12B of themagnetic body 13B via the inner surface of theinner panel 202, and thus the distance between themagnetic sensor 23B and theleg portion 12B of themagnetic body 13B is minimum. - The
magnet 21B of theinner panel 202 is formed as an acting unit that generates a magnetic field. A magnetic force based on the magnetic field acts to magnetize themagnetic body 13B in theouter panel 102, thereby attracting thebase portion 11B of the magnetic body. That is, themagnet 21B and thebase portion 11B of themagnetic body 13B attract each other by the magnetic attraction force, and thus theinner panel 202 can hold theouter panel 102. - The
magnetic sensor 23B detects the magnetic force of theleg portion 12B of themagnetic body 13B magnetized in theouter panel 102. For example, similar to themagnetic sensor 23A, themagnetic sensor 23B can be a Hall sensor formed using a Hall element. This can detect the attachment of theouter panel 102 to theinner panel 202. - The
magnetic sensor 23B of theinner panel 202 is configured not to detect a magnetic field generated by each of the twomagnets inner panel 202. For example, on the inner surface of theinner panel 202, themagnetic sensor 23B is arranged at a position separated from the twomagnets inner panel 202. This can set the influence of the magnetic fields from the twomagnets magnetic sensor 23B to approximately zero. - The distance between the
magnetic sensor 23B and themagnet 21B (or the magnet 27) of theinner panel 202 can be set to be larger than the distance between themagnetic sensor 23B and themagnetic body 13B in the state in which theouter panel 102 is attached to theinner panel 202. Thus, when detecting the attachment of theouter panel 102 to theinner panel 202, it is possible to appropriately consider only the magnetic field applied from theleg portion 12B of themagnetic body 13B in themagnetic sensor 23B without considering the influence of the magnetic field of the twomagnets - In an example, the
outer panel 102 can be configured so that data measured by themagnetic sensor 23B changes depending on the type of theouter panel 102 when theouter panel 102 is attached to theinner panel 202. More specifically, theouter panel 102 is configured so that data concerning the magnetizedmagnetic body 13B (that is, the magnitude of the magnetic force detected by themagnetic sensor 23B), which is detected by themagnetic sensor 23B of theinner panel 202, changes depending on the type of the panel. - For example, the
outer panel 102 is configured so that the distance between theleg portion 12B of themagnetic body 13B and its facingmagnetic sensor 23B changes depending on the type of the outer panel in the state in which theouter panel 102 is attached to theinner panel 202. That is, the shape of the curved surface may be adjusted for each type of panel so that the height of the inner surface of theouter panel 102 changes depending on the type. Thus, the commonmagnetic body 13B is used in any type of theouter panel 102, which is advantageous in manufacturing. - In another example, the position of the
magnetic body 13B may be shifted so as to change depending on the type of the panel along the inner surface of the facingouter panel 102. This can change the distance between themagnetic body 13B and themagnetic sensor 23B in accordance with the type of the panel. That is, the magnitude of the magnetic force detected by themagnetic sensor 23B can be changed in accordance with the type of the panel. - The arrangement examples for the attaching the
outer panel 102 to theinner panel 202 using the magnets have been described above but the present invention is not limited to them. Another arrangement may be adopted as long as it is possible to detachably attach theouter panel 102 to theinner panel 202 and to detect an attached/detached state. - An example of the functional arrangement of the
power source unit 101 will be described next with reference toFIG. 5 . Note that functional blocks to be described may be integrated or separated, and each function to be described may be implemented by another block. A component to be described as a hardware component may be implemented by a software component and vice versa. - A
control unit 120 controls the operation of thepower source unit 101. Thecontrol unit 120 may include one or more processors and a volatile memory. The processor may be, for example, a CPU (Central Processing Unit) or a microcontroller. Thecontrol unit 120 controls all the functions of theinhaler 100 by loading a computer program (also called software or firmware) stored in astorage unit 121 into the memory and executing the loaded program. Thestorage unit 121 can be, for example, a nonvolatile memory. Thestorage unit 121 stores one or more computer programs, and data describing a control sequence (heating profile) for controlling aheating unit 130. Note that theheating unit 130 is a functional unit that heats thestick 110, and is formed by the above-described heater H. - The
control unit 120 can control communication (pairing or connection in a normal state) with an external communication device. Furthermore, thecontrol unit 120 can control transition of the state of theinhaler 100 to be described later in accordance with a user operation on the action button B or theslider 105. Thecontrol unit 120 controls supply of electric power from abattery 132 to theheating unit 130. In response to an aerosol generation request, thecontrol unit 120 can start to supply electric power from thebattery 132 as a power supply to theheating unit 130. Thecontrol unit 120 controls the temperature of theheating unit 130 by adjusting the duty ratio of a control pulse by pulse width modulation (PWM). Note that thecontrol unit 120 may use pulse frequency modulation (PFM) instead of PWM. - An
input detection unit 122 detects, for example, an operation input to the action button B. Theinput detection unit 122 detects a user operation performed by, for example, pushing theouter panel 102, and outputs an input signal indicating this user operation to thecontrol unit 120. Note that theinhaler 100 may detect pushing itself of theouter panel 102, instead of detecting the pressing of the action button B. - A
state detection unit 123 detects the open/closed state of theslider 105. Thestate detection unit 123 can be formed by, for example, a Hall sensor including a Hall element. Thestate detection unit 123 outputs, to thecontrol unit 120, a state detection signal indicating whether theslider 105 is open or closed. Furthermore, thestate detection unit 123 can also detect an attached/detached state of theouter panel 102. Therefore, thestate detection unit 123 can include, for example,magnetic sensors state detection unit 123 can output a state detection signal indicating the attached/detached state of theouter panel 102 to thecontrol unit 120. - An inhalation detection unit 124 (puff sensor) can detect inhalation (puff) of the
stick 110 by the user. For example, theinhalation detection unit 124 can include a thermistor disposed near theopening 106. In this case, theinhalation detection unit 124 can detect inhalation by the user based on a change in resistance value of the thermistor resulting from a temperature change caused by the inhalation. As another example, theinhalation detection unit 124 may include a pressure sensor disposed on the bottom of the holdingportion 107. In this case, theinhalation detection unit 124 can detect inhalation based on a reduction in atmospheric pressure resulting from an air current caused by the inhalation. Theinhalation detection unit 124 outputs, to thecontrol unit 120, for example, an inhalation detection signal indicating whether inhalation is performed. - A
light emitting unit 125 includes one or more LEDs and a driver for driving the LEDs, thereby forming the display D. Thelight emitting unit 125 turns on each LED in accordance with an instruction signal input from thecontrol unit 120. Avibration unit 126 forms the above-described vibration generation unit V. Thevibration unit 126 can include a vibrator (for example, an eccentric motor) and a driver for driving the vibrator. Thevibration unit 126 vibrates the vibrator in accordance with an instruction signal input from thecontrol unit 120. Thecontrol unit 120 may control at least one of thelight emitting unit 125 and thevibration unit 126 in an arbitrary pattern, in order to notify the user of a certain status (for example, the status of pairing or detachment of the outer panel 102) of theinhaler 100. For example, the light emission patterns of thelight emitting unit 125 can be distinguished by elements such as the light emission state (always on/blinking/off), the blinking period, and the light color of each LED. The vibration patterns of thevibration unit 126 can be distinguished by elements such as the vibration state (vibration/stop) and the vibration strength of the vibrator. - A communication OF 127 includes, for example, a communication circuit and an antenna, and serves as a communication interface with which the
inhaler 100 wirelessly communicates with an external communication device (for example, a smartphone, a personal computer, or a tablet terminal owned by the user). The communication OF 127 can be, for example, an interface complying with an arbitrary wireless communication protocol, for example, short-range wireless communication such as Bluetooth®, near-field wireless communication such as NFC (Near Field Communication), or a wireless LAN (Local Area Network). - A connection OF 128 is a wired interface having a terminal for connecting the
inhaler 100 to another external device. The connection OF 128 can be a chargeable interface such as a USB (Universal Serial Bus) interface. The connection OF 128 may be used to charge thebattery 132 from an external power supply (charger) (via a feeder (not shown)). - The
battery 132 is a chargeable battery (secondary battery) such as a lithium-ion battery. Alternatively, thebattery 132 may be formed by an electric double-layer capacitor such as a lithium-ion capacitor. Aresidual amount meter 133 can include an IC chip for monitoring the residual power amount and other statuses of thebattery 132. Theresidual amount meter 133 can periodically measure the status values of thebattery 132, such as the SOC (State Of Charge), the SOH (State Of Health), the RSOC (Relative SOC), and the power supply voltage, and can output the measurement results to thecontrol unit 120. - <Operation Modes>
- An example of transition of the state of the
power source unit 101 will be described with reference toFIG. 6 . Thecontrol unit 120 has a plurality of operation modes. The plurality of modes can include, for example, asleep mode 61, anactive mode 62, anaerosol generation mode 63, a chargingmode 64, anunlock setting mode 65, and apairing mode 66. - The
sleep mode 61 is a state in which the operation by thecontrol unit 120 is temporarily stopped to stand by in a power-saving state in which the power consumption is reduced. The speed mode is a state in which theinhaler 100 stops the main operation, and no electric power is supplied to the heater H. Display on the display D is not performed. In other words, in thesleep mode 61, thepower source unit 101 is locked and the user cannot inhale aerosol. In thesleep mode 61, thecontrol unit 120 can accept a predetermined user input, and can transition to another mode corresponding to the user input upon accepting the corresponding user input. Note that in the following description, the speed mode will sometimes be referred to as a standby state. In this embodiment, thesleep mode 61 can be started by a method of “suspend” or “standby” by which the standby state begins while the contents of the memory of thecontrol unit 120 are maintained, and can also be started by a method of “hibernation” by which the standby state begins while the contents of the memory of thecontrol unit 120 are copied to thestorage unit 121. In thesleep mode 61, functions need not be operable except for the function of detecting a user operation on theslider 105 or the action button B, and the function of monitoring the residual battery amount. - In the
sleep mode 61, for example, if an operation of opening the slider 105 (an operation of setting the shutter open state) is performed, thecontrol unit 120 can transition to theactive mode 62. Theactive mode 62 can be a standby mode of standing by for detection of an unlock operation using the action button B while performing at least display by the display D. In theactive mode 62, if an operation of closing the slider 105 (an operation of setting the shutter closed state) is performed or if a non-operation state in which no user operation is performed for thepower source unit 101 continues for a predetermined time, thecontrol unit 120 can return to thesleep mode 61 in which display on the display D is stopped to stand by in the power-saving state. - In the
active mode 62, upon detecting an unlock operation, thecontrol unit 120 unlocks the locked state of thepower source unit 101, and can transition to theaerosol generation mode 63 in which aerosol is generated. The unlock operation can be, for example, one pressing operation of the action button B. However, as will be described later, the unlock operation can be changed by setting. For example, the unlock operation can be an operation of repeatedly pressing the action button B a predetermined number of times (for example, three times) within a predetermined time, an operation of pressing the action button B for a predetermined time (for example, 3 sec), or a combination thereof. In theaerosol generation mode 63, theheating unit 130 performs heating (that is, supplies electric power to the heater H), and the user can inhale aerosol. Alternatively, the setting of the unlock operation may be disabled, and transition to theaerosol generation mode 63 may be performed in response to detection, by the inhalation detection unit 124 (puff sensor), of inhalation (puff) by the user. When the inhalation ends, or the inhalation time reaches a predetermined upper limit time (MaxLoadingTime), thecontrol unit 120 can return to theactive mode 62. - When an external power supply (charger) is connected to the connection OF 128 in the
sleep mode 61 or the active mode 62 (or the aerosol generation mode 63), thecontrol unit 120 transitions to the chargingmode 64 and thebattery 132 is charged. When the external power supply is detached from the connection OF 128 or thebattery 132 is in a full charge state, thecontrol unit 120 transitions to thesleep mode 61. - In the charging
mode 64, for example, if a predetermined operation is performed on the action button B, thecontrol unit 120 can transition to theunlock setting mode 65. In theunlock setting mode 65, the unlock operation is set. For example, the unlock operation in a default state can be, for example, one pressing operation of the action button B. In theunlock setting mode 65, the user can change this unlock operation to another operation. For example, the unlock operation can be set to an arbitrary pattern such as an operation of repeatedly pressing the action button B a predetermined number of times within a predetermined time, an operation of pressing the action button B for a predetermined time, or a combination thereof. This can improve security performance of thepower source unit 101. When the setting ends, thecontrol unit 120 returns to the chargingmode 64. Note that in this embodiment, transition to theunlock setting mode 65 is performed from the chargingmode 64 but transition to theunlock setting mode 65 may be performed from an operation mode other than the chargingmode 64. - If a predetermined pairing operation is performed in the
sleep mode 61, thecontrol unit 120 can transition to thepairing mode 66 for executing pairing with an external communication device. Pairing is processing of associating thepower source unit 101 with an external communication device, and can be performed with, for example, the external communication device in compliance with Bluetooth®. The pairing operation can be, for example, an operation of pressing the action button B while theslider 105 is closed. In thepairing mode 66, if pairing with the external communication device succeeds, thecontrol unit 120 registers identification information of the paired device in a white list stored in thestorage unit 121. If registration in the white list succeeds or pairing fails, thecontrol unit 120 can transition from thepairing mode 66 to thesleep mode 61. - <Operation of Power Source Unit in Each Operation Mode>
- Examples of the operation of the
power source unit 101 will be described with reference toFIGS. 7 to 12 . This operation is controlled by thecontrol unit 120. -
FIG. 7 shows a control sequence in thesleep mode 61. In thesleep mode 61, thepower source unit 101 is in the standby state. In step S101, thecontrol unit 120 determines whether the external power supply (charger) is connected to the connection OF 128 to start charging of thebattery 132. If charging is detected, thecontrol unit 120 advances to step S104, and leaves thesleep mode 61 to transition to theactive mode 62. - In step S102, the
control unit 120 determines the open/closed state of theslider 105 based on a state detection signal from thestate detection unit 123. If the shutter open state is detected, thecontrol unit 120 advances to step S103, and leaves thesleep mode 61 to transition to theactive mode 62. - In step S105, the
control unit 120 determines whether a pairing operation of pressing the action button B is performed in the shutter closed state (NO in step S102). If no pairing operation is detected, the process returns to step S101. On the other hand, if a pairing operation is detected, thecontrol unit 120 transitions to the pairing mode (step S107). However, in this embodiment, in step S106, it is confirmed based on the output signal of thestate detection unit 123 that theouter panel 102 is attached to thepower source unit 101, and thecontrol unit 120 advances to step S107, and transitions to the pairing mode. In step S106, if theouter panel 102 is detached from thepower source unit 101, thecontrol unit 120 does not transition to the pairing mode as the function restriction, and the process returns to step S101. At this time, the pairing operation may be disabled. -
FIG. 8 shows a control sequence in theactive mode 62. After entering theactive mode 62, thecontrol unit 120 acquires the residual battery amount in step S201. For example, thecontrol unit 120 can acquire the residual battery amount based on the output voltage of thebattery 132. Alternatively, thecontrol unit 120 can acquire the residual battery amount based on the number of times of puff after the completion of charging, which is acquired from theinhalation detection unit 124. Alternatively, if thepower source unit 101 includes a management circuit that manages thebattery 132, thecontrol unit 120 can acquire the residual battery amount based on an output from the management circuit. - In step S202, the
control unit 120 determines whether the residual battery amount exceeds a predetermined threshold. The predetermined threshold is a threshold for determining whether to permit the operation in theactive mode 62 with respect to the residual battery amount. More specifically, the predetermined threshold can be set as, for example, the predetermined lower limit value of the residual battery amount with which even generation of aerosol corresponding to N (for example, N=1) puff operations is impossible. If the residual battery amount is equal to or smaller than the predetermined threshold, thepower source unit 101 cannot operate in theactive mode 62. Therefore, in step S203, thecontrol unit 120 makes a notification by the display D and/or the vibration generation unit V, and then returns to thesleep mode 61 in step S204. - If the residual battery amount exceeds the predetermined threshold, the process advances to step S205. In step S205, the
control unit 120 displays the residual battery amount on the display D. After that, in step S206, thecontrol unit 120 determines whether a condition for returning to thesleep mode 61 is satisfied. The condition for returning to thesleep mode 61 can be, for example, a condition that theslider 105 is operated to be set in the shutter closed state or a condition that a non-operation period exceeds a predetermined time. If this condition is satisfied, thecontrol unit 120 transitions to thesleep mode 61 in step S204. - If it is determined in step S206 that the condition for returning to the
sleep mode 61 is not satisfied, thecontrol unit 120 determines in step S207 whether an unlock operation is performed. If an unlock operation is detected, thecontrol unit 120 determines in step S208 whether theouter panel 102 is attached to thepower source unit 101. If theouter panel 102 is attached to thepower source unit 101, thecontrol unit 120 transitions to theaerosol generation mode 63 in step S209. - On the other hand, if it is determined that the
outer panel 102 is detached from thepower source unit 101, thecontrol unit 120 makes, in step S210, a notification by the display D and/or the vibration generation unit V, and the process returns to step S201. That is, even if an unlock operation is detected in the state in which theouter panel 102 is detached, thecontrol unit 120 does not transition to theaerosol generation mode 63 as the function restriction. At this time, the unlock operation may be disabled. Note that in this case, thecontrol unit 120 may transition to thesleep mode 61 instead of returning to step S201. - An overview of the operation in the
active mode 62 has been described above. According to the control sequence shown inFIG. 8 , in the state in which theouter panel 102 is detached, even if an unlock operation is input, thecontrol unit 120 cannot transition to theaerosol generation mode 63. At this time, the unlock operation may be disabled. However, even if the detachment of theouter panel 102 is detected in step S208, theactive mode 62 is maintained, and the residual battery amount can continuously be displayed in step S205. - Note that in the sequence of
FIG. 8 , transition to the chargingmode 64 is not illustrated. As described above, even in theactive mode 62, it is monitored that the external power supply (charger) is connected to the connection OF 128. If the external power supply (charger) is connected to the connection OF 128 in theactive mode 62, thebattery 132 can also be charged. -
FIG. 9 shows a control sequence in theaerosol generation mode 63. After transitioning to theaerosol generation mode 63, thecontrol unit 120 first confirms, in step S301, that theouter panel 102 is attached to the power source unit 101 (the inner panel 202). If theouter panel 102 is attached to thepower source unit 101, thecontrol unit 120 starts, in step S302, to supply electric power to the heater H by theheating unit 130. Power supply to the heater H can be controlled in accordance with a predetermined control sequence (heating profile). After a preheating period in the heating profile, theinhaler 100 enters the inhalation enable state. - In step S303, the
control unit 120 determines whether an aerosol generation end condition is satisfied. The aerosol generation end condition can be, for example, a condition that the number of times of puff after entering the inhalation enable state, which is acquired from theinhalation detection unit 124, has reached a predetermined number, a condition that a predetermined time has elapsed after transitioning to theaerosol generation mode 63, or the like. If the aerosol generation end condition is satisfied, the process advances to step S304, and thecontrol unit 120 stops the power supply to the heater H. After that, in step S305, thecontrol unit 120 transitions to theactive mode 62. - If it is determined in step S301 that the
outer panel 102 is detached from thepower source unit 101, thecontrol unit 120 makes, in step S306, a notification by the display D and/or the vibration generation unit V, and prohibits, in step S307, power supply to the heater H as the function restriction. After that, in step S308, thecontrol unit 120 may determine whether theouter panel 102 is attached to thepower source unit 101. While theouter panel 102 is not attached to thepower source unit 101, the determination processing in step S308 can be repeated for a predetermined time. However, if the predetermined time elapses (YES in step S310), thecontrol unit 120 transitions to theactive mode 62 in step S311. If the attachment of theouter panel 102 to thepower source unit 101 is detected within the predetermined time, thecontrol unit 120 cancels, in step S309, the prohibition of the power supply to the heater H as the function restriction. After that, the process returns to step S301. - Note that although not illustrated, acquisition and display of the residual battery amount can appropriately be performed even in the
aerosol generation mode 63, similar to theactive mode 62. Even in the state in which theouter panel 102 is detached, display of the residual battery amount may be continued without being prohibited. -
FIG. 10 shows a control sequence in thepairing mode 66. After entering thepairing mode 66, thecontrol unit 120 acquires the residual battery amount in step S401. For example, thecontrol unit 120 can acquire the residual battery amount based on the output voltage of thebattery 132. Alternatively, thecontrol unit 120 can acquire the residual battery amount based on the number of times of puff after the completion of charging, which is acquired from theinhalation detection unit 124. Alternatively, if thepower source unit 101 includes a management circuit that manages thebattery 132, thecontrol unit 120 can acquire the residual battery amount based on an output from the management circuit. - In step S402, the
control unit 120 determines whether the residual battery amount exceeds a predetermined threshold. The predetermined threshold is a threshold for determining whether to permit the operation in thepairing mode 66 with respect to the residual battery amount. More specifically, the predetermined threshold can be set as the predetermined lower limit value of the residual battery amount by assuming that electric power shortage does not occur during pairing processing. If the residual battery amount is equal to or smaller than the predetermined threshold, thepower source unit 101 cannot operate in thepairing mode 66. Therefore, in step S403, thecontrol unit 120 makes a notification by the display D and/or the vibration generation unit V, and then advances to step S413 to return to thesleep mode 61. - If the residual battery amount exceeds the predetermined threshold, the process advances to step S404. In step S404, the
control unit 120 displays the residual battery amount on the display D. After that, in step S405, thecontrol unit 120 determines whether theouter panel 102 is attached to thepower source unit 101. If it is determined that theouter panel 102 is detached from thepower source unit 101, thecontrol unit 120 makes, in step S406, a notification by the display D and/or the vibration generation unit V, and advances to step S413 to return to thesleep mode 61. As described above, in this embodiment, if the detachment of theouter panel 102 is detected in thepairing mode 66, thecontrol unit 120 prohibits execution of pairing as the function restriction. In this case, thecontrol unit 120 leaves thepairing mode 66, and transitions to thesleep mode 61. If it is determined that theouter panel 102 is detached from thepower source unit 101 in thepairing mode 66, the pairing operation performed so far may be canceled. - If it is determined in step S405 that the
outer panel 102 is attached to thepower source unit 101, thecontrol unit 120 executes, in step S407, pairing complying with Bluetooth® with an external communication device. In step S408, thecontrol unit 120 determines whether the pairing processing has succeeded or failed. For example, if a time-out occurs before the completion of the pairing processing, an error is notified from the external communication device, or a cancel operation of the pairing processing is detected, thecontrol unit 120 can determine a pairing failure. Furthermore, if it is detected that theouter panel 102 is detached from thepower source unit 101 during the pairing processing, thecontrol unit 120 interrupts the pairing processing, and determines a pairing failure. - If it is determined in step S408 that the pairing processing has succeeded, the
control unit 120 makes, in step S409, a notification that the pairing processing has succeeded, by the display D and/or the vibration generation unit V. After that, in step S410, thecontrol unit 120 determines whether a pairing cancellation condition is satisfied. The pairing cancellation condition can be, for example, a condition that theslider 105 is operated to be set in the shutter open state, a condition that the action button B is pressed, a condition that a pairing cancellation request is received from the external communication device, a condition that a non-operation period exceeds a predetermined time, or the like. If the pairing cancellation condition is satisfied, thecontrol unit 120 performs, in step S411, processing of disconnecting Bluetooth connection from the external communication device, and transitions to thesleep mode 61 in step S413. - If it is determined in step S408 that the pairing processing has failed, the
control unit 120 makes, in step S412, a notification that the pairing processing has failed, by the display D and/or the vibration generation unit V. After that, in step S413, thecontrol unit 120 transitions to thesleep mode 61. -
FIG. 11 shows a control sequence in the chargingmode 64. After entering the chargingmode 64, thecontrol unit 120 acquires the residual battery amount in step S501. For example, thecontrol unit 120 can acquire the residual battery amount based on the output voltage of thebattery 132. Alternatively, thecontrol unit 120 can acquire the residual battery amount based on the number of times of puff after the completion of charging, which is acquired from theinhalation detection unit 124. Alternatively, if thepower source unit 101 includes a management circuit that manages thebattery 132, thecontrol unit 120 can acquire the residual battery amount based on an output from the management circuit. After that, in step S502, thecontrol unit 120 displays the residual battery amount on the display D. - In step S503, the
control unit 120 determines whether an unlock setting operation is performed. The unlock setting operation can be, for example, a combination of an operation of opening/closing theslider 105 and a predetermined number of times of continuous pressing of the action button B. If no unlock setting operation is detected, thecontrol unit 120 determines in step S504 whether charging has ended. If, for example, the external power supply (charger) is detached from the connection OF 128 or thebattery 132 is set in the full charge state, it can be determined that charging has ended. If it is determined that charging has not ended, the process returns to step S501. If it is determined that charging has ended, thecontrol unit 120 transitions to thesleep mode 61 in step S507. - If the unlock setting operation is detected in step S503, the
control unit 120 determines in step S505 whether theouter panel 102 is attached to thepower source unit 101. If theouter panel 102 is attached to thepower source unit 101, thecontrol unit 120 transitions to theunlock setting mode 65 in step S506. If theouter panel 102 is not attached to thepower source unit 101, thecontrol unit 120 does not transition to theunlock setting mode 65, and the process advances to step S504. That is, even if the unlock setting operation is detected in the state in which theouter panel 102 is detached, thecontrol unit 120 does not transition to theunlock setting mode 65 as the function restriction. The unlock setting operation may be disabled. Note that if theouter panel 102 is not attached to thepower source unit 101, a notification of it may be made. - As described above, in this embodiment, even if the detachment of the
outer panel 102 is detected in the chargingmode 64, thebattery 132 is continuously charged. However, transition to theunlock setting mode 65 in the state in which theouter panel 102 is detached is not permitted. In another embodiment, charging processing may also not be permitted in the state in which theouter panel 102 is detached. -
FIG. 12 shows a control sequence in theunlock setting mode 65. After entering theunlock setting mode 65, thecontrol unit 120 accepts the input of an unlock operation pattern in step S601. As described above, the unlock operation is an operation for transitioning from theactive mode 62 to theaerosol generation mode 63. In step S601, for example, an unlock operation pattern input within a predetermined time (for example, 20 sec) after transition to theunlock setting mode 65 is accepted. - In step S602, the
control unit 120 determines whether theouter panel 102 is attached to thepower source unit 101. If theouter panel 102 is attached to thepower source unit 101, thecontrol unit 120 stores, in step S603, the unlock operation pattern accepted in step S601 in thestorage unit 121. After that, thecontrol unit 120 returns to the chargingmode 64 in step S605. - If it is determined in step S602 that the
outer panel 102 is not attached to thepower source unit 101, thecontrol unit 120 discards, in step S604, data of the unlock operation pattern input in step S601. After that, thecontrol unit 120 returns to the chargingmode 64 in step S605. As described above, in this embodiment, if the detachment of theouter panel 102 is detected in theunlock setting mode 65, thecontrol unit 120 prohibits execution of setting of the unlock operation as the function restriction, and cancels the unlock operation pattern input so far. - Note that although not illustrated, acquisition and display of the residual battery amount can appropriately be performed even in the
unlock setting mode 65, similar to theactive mode 62 or the like. Even in the state in which theouter panel 102 is detached, display of the residual battery amount may be continued without being prohibited. As described above, in the operation modes other than thesleep mode 61, even if the detachment of theouter panel 102 is detected, thecontrol unit 120 can continue display by the display D. - The operation of the
power source unit 101 in each operation mode has been explained above. In the above-described embodiment, in any of the plurality of operation modes, in the state in which theouter panel 102 is detached, the operation of the action button B can be disabled. However, in each operation mode, if the detachment of theouter panel 102 is detected, only the function associated with the operation mode is restricted, and the operations of the remaining functions can be continued. For example, in the active mode 62 (FIG. 8 ), even if theouter panel 102 is detached, display of the residual battery amount is not stopped. In the charging mode 64 (FIG. 11 ), even if theouter panel 102 is detached, charging is not stopped. - With respect to a function that can depend on user selection, a tool for prompting the user to make selection may be provided. At this time, the
control unit 120 can function as a setting unit for setting contents of the function restriction on the plurality of functions. For example, in thepairing mode 66, a setting screen shown inFIG. 13 may be displayed on the display unit of a paired external communication device, and the user may be able to select, for each of the plurality of functions, prohibition/non-prohibition of the operation of the function in the state in which theouter panel 102 is detached. Referring toFIG. 13 , a hatched portion indicates a selection result by the user. The selection result of each function is stored in thestorage unit 121. Thecontrol unit 120 can execute control when theouter panel 102 is detached, in accordance with the selection information stored in thestorage unit 121. - According to the above-described embodiment, the
control unit 120 is configured to impose, if the detachment of theouter panel 102 is detected, a function restriction on the plurality of functions controlled by thecontrol unit 120. Then, thecontrol unit 120 has the plurality of operation modes, and contents of the function restriction are different for each operation mode. This can maintain user convenience. Among others, in the state in which theouter panel 102 is detached, heating by power supply to the heater H is prohibited, and thus safety is also ensured. Therefore, according to this embodiment, there is provided an inhaler power source unit advantageous in both safety and user convenience. - The foregoing description of the exemplary embodiments of the present invention has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously, many modifications and variations will be apparent to practitioners skilled in the art. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, thereby enabling others skilled in the art to understand the invention for various embodiments and with the various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the following claims and their equivalents.
