Description

[Technical field]

[0001] The present invention relates to a controller for an aspirator. [Background technology]

[0002] In an aerosol generating device that generates a respirable aerosol, the number of puffing operations (inhalation operations) that can be performed per charge can be an important indicator. In order to improve such an indicator, it is important to reduce the power consumption of the display unit, etc., of the aerosol generating device.

[0003] Patent Document 1 describes the use of electronic paper (e-ink) in the display of an electronic cigarette to reduce power consumption. In addition, Patent Document 2 and Patent Document 3 also describe the use of e-ink in the display of an inhaler. However, Patent Documents 1, 2, and 3 do not disclose the timing or conditions under which the display of the electronic paper is updated, and therefore do not provide any technical significance beyond the use of electronic paper as a display device.

[0028] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0029] The configuration of an inhaler 100, which is one form of an aerosol generating device, will be described with reference to Figs. 1, 2, and 3. Fig. 1 shows an exploded perspective view of the inhaler 100, Fig. 2 shows a completed assembly view (front view, side view, and perspective view) of the inhaler 100, and Fig. 3 shows an internal configuration view of the inhaler 100. The inhaler 100 may be configured to provide an aerosol, an aerosol having a flavor, or a gas containing an aerosol and a flavoring substance, or an aerosol or an aerosol containing a flavoring substance to a user through the mouthpiece 130 in response to an action requesting the generation of an aerosol, such as a user's inhalation action (hereinafter also referred to as an "atomization request"). The inhaler 100 may include a power supply unit 102 as an inhaler controller, an atomizer 104, a capsule holder 105, and a capsule 106.

[0030] The atomizer 104 may be configured to generate a flavored aerosol from an aerosol source. The aerosol source may be a liquid, such as a polyhydric alcohol, such as glycerin or propylene glycol. Alternatively, the aerosol source may include a drug. The aerosol source may be a liquid, a solid, or a mixture of a liquid and a solid. Instead of the aerosol source, a vapor source such as water may be used. The atomizer 104 may be provided as a cartridge that is detachable from the power supply unit 102. The atomizer 104 may be attached to the power supply unit 102 in a non-detachable manner. In this specification, the atomizer 104 may be described as a cartridge 104. The power supply unit 102 may be understood as a drive unit that drives the atomizer 104, a holder that holds the atomizer 104, or a main body that causes the atomizer 104 to function.

[0031] The power supply unit 102 may have a holding portion 103 for holding the atomizer 104. The holding portion 103 may be configured to accommodate the whole or a part of the atomizer 104. The holding portion 103 may further be configured to hold a capsule holder 105. Alternatively, the capsule holder 105 may be held by the atomizer 104. The capsule holder 105 holds a capsule 106. The capsule holder 105 may function to fix the atomizer 104 in cooperation with the holding portion 103.

[0032] The holding part 103 may include a locking mechanism that prevents the capsule holder 105 from falling off from the holding part 103. The locking mechanism may include a second engagement part that engages with a first engagement part that may be provided on the capsule holder 105. When the locking mechanism is activated, i.e., when the capsule holder 105 is locked by the locking mechanism, the connection parts 113 and 114 of the atomizer 104 are pressed against the connection parts 111 and 112 of the power supply unit 102, respectively, and electrical connection between the connection parts 113 and 114 and the connection parts 111 and 112, respectively, may be provided.

[0033] The capsule holder 105 may be integrated with the atomizer 104 or the power supply unit 102. Furthermore, when the capsule 106 is inserted into the opening of the capsule holder 105, gas may be able to flow between the atomizer 104 and the capsule 106. The capsule 106 may include a flavor source 131. The flavor source 131 may be, for example, a molded body made by molding tobacco material. Alternatively, the flavor source 131 may be made of plants other than tobacco (for example, mint, herbs, Chinese medicine, coffee beans, etc.). The flavor source may be imparted with a flavoring such as menthol. The flavor source 131 may be added to the aerosol source. A user can hold the mouthpiece 130 formed at the tip of the capsule 106 in his mouth and inhale the flavored aerosol.

[0034] The power supply unit 102 may include an electric component 110. The electric component 110 may include a user interface 116. Alternatively, the power supply unit 102 may be understood as including the electric component 110 and the user interface 116. The user interface 116 may include an action button B as an operation unit operable by a user. The action button B may be a button for triggering an operation such as starting up the power supply unit 102 or displaying information.

[0035] The user interface 116 may further include a first display D1 as a first notification unit and a second display D2 as a second notification unit. The first display D1 and the second display D2 may have different display principles, and in this case, the power consumption may be different from each other. For example, the first display D1 may be an organic light-emitting diode (OLED) display, and the second display D1 may be an electronic paper (e-ink) display. The electronic paper (e-ink) display is a type of non-volatile display. The OLED display that may be adopted as the first display D1 does not require a backlight device as required for a liquid crystal display, since the organic light-emitting diode emits light by itself. The electronic paper display that may be adopted as the second display D2 does not require power to continue to hold an image. Therefore, the electronic paper display consumes less power than the OLED display. However, the electronic paper display does not have a self-emitting function like the OLED display, and is less visible in a dark environment than the OLED display.

[0036] The user interface 116 may further include a third notification unit in addition to the first display D1 and the second display D2. The third notification unit may include a third display D3 and / or a vibration generating unit V. For example, a light-emitting diode (LED) display may be adopted as the third display D3. In one example, the LED display may be composed of 10 or less, 20 or less, or 30 or less LEDs. In this case, the LED display can display less information than an electronic paper display, but has high visibility because it can achieve high brightness. Alternatively, the LED display may be a display composed of an LED array.

[0037] The vibration generating unit V may be configured with a vibration motor for vibrating the housing of the power supply unit 102. By vibrating the housing with the vibration motor, the state of the power supply unit 102 can be notified to the user holding it. In one example, the power consumption of the first display D1 and the power consumption of the third display are greater than the power consumption of the second display D2, and the power consumption of the first display D1 is greater than the power consumption of the third display D3 or the vibration generating unit V.

[0038] FIG. 2 shows an example of the arrangement of the action button B, the first display D1, the second display D2, and the third display D3. In the example of FIG. 2, the first display D1 is arranged on the upper surface of the power supply unit 102, and the second display D2 and the third display D3 are arranged on different sides of the power supply unit 102. However, the arrangement locations of the displays D1, D2, and D3 may be interchanged with each other, or may be arranged in a location different from the location shown in the figure. The third display D3 (e.g., an LED display) may be arranged around a window portion for visually checking the remaining amount of the aerosol source in the atomizer 104, as shown in the side view in FIG. 2, for example. Alternatively, the third display D3 may be arranged around the action button B. The arrangement location of the action button B is not limited to the example shown in the figure, and may be arranged in another location.

[0039] The power supply unit 102 may include a first connection portion 111 and a second connection portion 112. In a state in which the atomizer 104 is held by the holding portion 103 and the capsule holder 105 is attached to the holding portion 103, the first connection portion 111 may be electrically connected to the third connection portion 113 of the atomizer 104, and the second connection portion 112 may be electrically connected to the fourth connection portion 114 of the atomizer 104. The first connection portion 111, the second connection portion 112, the third connection portion 113, and the fourth connection portion 114 may be electrical contacts or connectors. The power supply unit 102 may supply power to the atomizer 104 through the first connection portion 111 and the second connection portion 112.

[0040] The atomizer 104 may include a third connection portion 113 and a fourth connection portion 114. The atomizer 104 may also include a heater 127 for generating a flavored aerosol from the aerosol source, a container 125 for holding the aerosol source, and a transport portion 126 for transporting the aerosol source held by the container 125 to a region heated by the heater 127 and holding the aerosol source in the heating region. At least a part of the heating region may be disposed in a flow path 128 provided in the atomizer 104. The first connection portion 111, the third connection portion 113, the heater 127, the fourth connection portion 114, and the second connection portion 112 form a current path for passing a current to the heater 127. The transport portion 126 may be composed of, for example, a fiber material such as glass fiber or a porous material such as ceramic, or a combination of these. In addition, such a transport portion 126 may also be called a wick. However, the means for transporting the aerosol source in the container 125 to the heating region is not limited to the wick, and may be realized by a spraying device such as a spray or a transporting means such as a pump.

[0041] When a user holds the mouthpiece 130 in his mouth and inhales, as shown by the dashed arrow, air flows into the flow path 128 of the atomizer 104 through an opening (not shown), and the aerosol source vaporized and / or aerosolized by the heater 127 heating the aerosol source is transported toward the mouthpiece 130 by the air. In the process of transporting toward the mouthpiece 130, the vaporized aerosol source is cooled to form minute droplets, which can promote aerosolization. In a configuration in which the flavor source 131 is disposed, a flavor substance generated by the flavor source 131 is added to the aerosol, and the aerosol having a flavor is transported to the mouthpiece 130 and inhaled into the mouth of the user. Since the flavor substance generated by the flavor source 131 is entrained in the aerosol, the flavor substance does not remain in the user's oral cavity, but can be efficiently transported to the user's lungs.

[0042] 4 shows an example of the configuration of the electric component 110. The electric component 110 can include a power source 205 and a charging circuit 206. The power source 205 can be a rechargeable battery (secondary battery) such as a lithium ion secondary battery. Alternatively, the power source 205 may be an electric double layer capacitor such as a lithium ion capacitor. The power source 205 can be, for example, a V bus It can be charged using the power supplied from the V bus A power supply device (external power source) (not shown) can be connected to the port via a cable. bus The ports, cables, and power sources may be configured to comply with standards such as Universal Serial Bus (USB) Type-A, Type-B, and Type-C. bus Through the port, power can be supplied to the power source 205. The power supply device can be a charger for a personal computer (PC), a portable battery, etc. bus When connected to a charger via a port and a cable, the power supply unit 102 and the charger communicate with each other, and then it may become possible for the charger to charge the power supply 205. Note that the connection between the power supply unit 102 and the power supply device is not limited to a USB interface, and various other communication methods capable of data communication and power supply may be applied.

[0043] The charging circuit 206 supplies a charging current from the charging terminal BAT to the power source 205 using power supplied from the power supply device to the input terminal IN, thereby charging the power source 205. The charging circuit 206 can also output power or voltage from the voltage output terminal OUT using power supplied from the power supply device. Therefore, even while the charging circuit 206 is charging the power source 205, power or voltage can be supplied from the charging circuit 206 to the voltage converters 202, 203, and 204. The charging circuit 206 is configured to supply a V busWhen no power supply device is connected to the port, power or voltage can be output from the voltage output terminal OUT using the power supplied to the charging terminal BAT from the power source 205. Therefore, even when the charging circuit 206 is not charging the power source 205, the charging circuit 206 can supply power or voltage to the voltage converters 202, 203, and 204.

[0044] The electric component 110 may include one or more voltage converters. When the electric component 110 includes a plurality of voltage converters, at least two of the voltage converters may generate voltages different from each other or equal to each other. In the configuration example shown in FIG. 4, the electric component 110 includes voltage converters 202, 203, and 204. The electric component 110 may not include a voltage converter. In this case, the voltage output by the power supply 205 may be provided to the plurality of elements constituting the electric component 110 with a slight voltage drop due to wiring resistance. In the configuration example shown in FIG. 4, the voltage converters 202 and 203 are configured by switching regulators such as DC / DC converters, but at least one of them may be configured by an LDO (Low DropOut) or may be configured by a circuit of another type. In the configuration example shown in FIG. 4, the voltage converter 204 is configured by an LDO (Low DropOut), but may be configured by a switching regulator such as a DC / DC converter or may be configured by a circuit of another type.

[0045] The electrical component 110 may include a processor 207 that operates according to pre-installed software (program). The processor 207 may be configured to control a plurality of elements that constitute the electrical component 110. The processor 207 may be configured, for example, as an MCU (Micro Controller Unit). The processor 207 may be replaced by another device such as an ASIC. A voltage (power) may be supplied to the processor 207 by a voltage converter 204. The processor 207 may be configured to control drivers 211, 212, 213, and 214 that are elements that constitute the electrical component 110. The drivers 211, 212, 213, and 214 drive the displays D1, D2, and D3, and the vibration motor V, respectively. Thus, the processor 207 may be understood as a processor that drives or controls the displays D1, D2, and D3, and the vibration motor V.

[0046] The processor 207 may be configured to determine whether to update the display of the second display D2 in response to the occurrence of a factor that changes the remaining amount of the aerosol source. Alternatively, the processor 207 may be configured to determine whether to update at least one of the display of the first display D1 and the third display D3 in addition to the second display D2 in response to the occurrence of a factor that changes the remaining amount of the aerosol source. The factor that changes the remaining amount of the aerosol source may be, for example, heating of the aerosol source to generate aerosol, in other words, supply of power to the heater 127 to generate aerosol (discharge from the power source 205 to the heater 127). Alternatively, the factor that changes the remaining amount of the aerosol source may include replacement of the cartridge 104 and replacement of the capsule 106.

[0047] Determining whether to update the display of the second display D2 in response to the occurrence of a factor that changes the remaining amount of the aerosol source is advantageous for preventing the decision to update from being made excessively frequently and for reducing power consumption in the power supply unit 102. Determining whether to update the display of the second display D2 in response to the occurrence of a factor that changes the remaining amount of the aerosol source is advantageous for quickly updating the display of the second display D2 in response to the occurrence of a factor that changes the remaining amount of the aerosol source. The frequency at which the processor 207 updates the display of the second display D2 in response to the occurrence of a factor that changes the remaining amount of the aerosol source may be less than the frequency of discharge from the power supply 205 to the heater 127.

[0048] The atomizer 104 may be understood as a first source that is a source of aerosol generation. The capsule 106 imparts flavor to the aerosol, and therefore may be understood as a second source of flavored aerosol. Alternatively, the second source may be understood as a source of flavor. The information providing function constituted by the displays D1, D2, and D3 may be realized by one or more non-volatile displays such as electronic paper. Alternatively, the factor that changes the remaining amount of the aerosol source may be the detection of a puff by the puff sensor 209, or an operation in response to the detection. The processor 207 may operate to update the display of all or a part of the displays D1, D2, and D3 (for example, the second display D2) when the discharge from the power source 205 to the heater 127 has ended and the discharge is not being performed. On the other hand, the processor 207 may operate not to update the display of the displays D1, D2, and D3 when the discharge from the power source 205 to the heater 127 is being performed.

[0049] A voltage (power) may be supplied to the drivers 211, 212, 213, and 214 by the voltage converter 204. The voltage converter 204 may also supply a voltage (power) to the action button B. When the action button B is switched from an off state to an on state by a user, it may supply a signal of an active level (e.g., a high level) to the processor 207. A voltage (power) may be supplied to the first display D1, which may be composed of an OLED, by the voltage converter 203. In the example shown in FIG. 4, the displays D2 and D3 and the vibration motor V are supplied with a voltage (power) from the drivers 212, 213, and 214, respectively. Alternatively, at least one of the displays D2 and D3 and the vibration motor V may be supplied with a voltage (power) from any of the voltage converters 202, 203, and 204.

[0050] The power supply unit 102 may include a puff sensor 209 that detects an inhalation action by a user, i.e., a puff, and the voltage converter 204 may also supply a voltage (power) to the puff sensor 209. The puff sensor 209 may detect a puff by detecting at least one of pressure, sound, and temperature (for example, the temperature of the air flowing into the flow path 128 of the atomizer 104 through the aforementioned opening, and the temperature of the heater 127).

[0051] The electric component 110 may include a switch 201 for controlling the energization (power supply) of the heater 127, which is a load of the atomizer 104. The switch 201 may be, for example, a MOSFET having a body diode, but may be configured with other switching elements. The voltage converter 202 may supply a voltage (power) to the heater 127 via the switch 201. A shunt resistor R shunt may be arranged.

[0052] The electrical component 110 may include a measurement circuit 210 for measuring the temperature of the heater 127. The heater 127 has a resistance R HTR The resistance R of the heater 127 may have a varying positive or negative temperature coefficient characteristic. HTRmay have a strong correlation with the temperature of the heater 127. The measurement circuit 210 measures the resistance R HTR The measurement circuit 210 may be configured, for example, by an operational amplifier to measure the voltage across the heater 127. The output of the measurement circuit 210 is provided to the processor 207, which determines the resistance value R based on the output of the measurement circuit 210 and the value of the current flowing through the heater 127. HTR The current value can be calculated, for example, by calculating the shunt resistance R shunt This can be achieved by using a detection circuit that detects the voltage across a shunt resistor R shunt may be a circuit that detects a potential difference between both ends of the heater 127, and may be provided in the processor 207 as, for example, an AD converter. The processor 207 may control the switch 201 so as to feedback control, for example, PID control, the temperature of the heater 127 based on the temperature of the heater 127 measured using the measurement circuit 210.

[0053] The electrical component 110 may include a first sensor 221 that detects the presence or absence of the cartridge 104 and a second sensor 222 that detects the presence or absence of the capsule 106. The outputs of the first sensor 221 and the second sensor 222 may be provided to the processor 207. The first sensor 221 and the second sensor 222 may be supplied with a voltage (power) by the voltage converter 204. The first sensor 221 and the second sensor 222 may be, for example, a photointerrupter, a proximity sensor, an RFID system, or a switch. The switch that detects the presence or absence of the cartridge 104 may be turned on (or off) by the insertion of the cartridge 104 into the holder 103, and turned off (or on) by the removal of the atomizer 104 from the holder 103. A switch that detects the presence or absence of the capsule 106 can be turned on (or off) by insertion of the capsule 106 into the holder 103 and turned off (or on) by removal of the capsule 106 from the holder 103.

[0054] With reference to the state transition diagram of FIG. 5, state transitions of the power supply unit 102 or the inhaler 100 in the embodiment and examples of display of the second display D2 in each state will be described. The power supply unit 102 can have four operation modes: a sleep mode, an active mode, an aerosol generation mode, and a charging mode. The first display D1 may also be controlled to display the same as the second display D2. Alternatively, the first display D1 and the third display D3 may be controlled to display a simplified version of the display content of the second display D2. Alternatively, the first display D1 and the third display D3 may display information to supplement the information displayed by the second display D1.

[0055] The sleep mode is a state in which the power supply unit 102 is suspended from major operations. In the sleep mode, no power is supplied to the heater 127 of the atomizer or cartridge 104 to heat the aerosol source. In the sleep mode, the power consumed by the power supply unit 102 may be minimized. The sleep mode may also be called a power saving mode or a standby mode. In the sleep mode, the aerosol supply function of the power supply unit 102 is locked, and the user cannot inhale the aerosol.

[0056] When a predetermined operation is performed on the action button B in the sleep mode, the lock is released and the power supply unit 102 transitions to the active mode. The predetermined operation may be, for example, an operation of repeatedly pressing the action button B a predetermined number of times (e.g., three times), an operation of pressing and holding the action button B for a specified time (e.g., three seconds) or more, etc. Also, when a predetermined time has passed in the active mode without a predetermined operation, the power supply unit 102 or the inhaler 100 may return to the sleep mode.

[0057] When the puff sensor 209 detects an inhalation (puff) by the user in the active mode, the power supply unit 102 transitions to an aerosol generation mode in which an aerosol is generated. When the inhalation ends or when the time for one inhalation reaches a specified upper limit time, the power supply unit 102 may return to the active mode. The active mode and the aerosol generation mode may be understood as a first mode in which the discharge from the power supply 205 to the heater 127 can be controlled, and the sleep mode may be understood as a second mode in which the power consumption is smaller than that of the first mode. In response to the operation of the action button B, the power supply unit 102 may transition from the active mode to the aerosol generation mode. In this case, the power supply unit 102 may return to the active mode in response to the detection of a predetermined number of inhalations in the aerosol generation mode or the passage of a predetermined time.

[0058] In sleep or active mode, the external power supply (charger) is V bus When connected to the port, the inhaler 100 transitions to a charging mode, where the power source 205 is charged. bus When the inhaler 100 is removed from the port or when the inhaler 100 is fully charged, the inhaler 100 goes into sleep mode. A fully charged state means that the SOC (State Of Charge) or the charging rate is 100% or a predetermined value close to the SOC (State Of Charge) (e.g., 98%, 95%, or 90%) or more. The power supply unit 102 or the inhaler 100 may have a function that allows the user to set a standard for determining a fully charged state.

[0059] FIG. 5b shows an example of the display of the second display D2 in the active mode. In this example, the second display D2 displays the remaining amount of the flavor source 131 in the capsule 106 (hereinafter referred to as the "capsule remaining amount"), the remaining amount of the aerosol source in the cartridge 104 (hereinafter referred to as the "cartridge remaining amount"), and the remaining amount of the power that the power source 205 can discharge (hereinafter referred to as the "battery remaining amount") in the form of a bar graph. FIG. 5a shows an example of the display of the second display D2 in the charging mode. Even in the charging mode, the capsule remaining amount, the cartridge remaining amount, and the battery remaining amount may be displayed. In the area where the battery remaining amount is displayed, a charging mark indicating that charging is in progress may be additionally displayed. FIG. 5c shows an example of the display of the second display D2 in the aerosol generation mode. Due to the generation of aerosol, the capsule remaining amount, the cartridge remaining amount, and the battery remaining amount each tend to decrease, so that the number of bars in at least one of the bar graphs decreases as shown in the left part of FIG. 5c. 5c indicates that the capsule is low and that the battery is empty. Thus, the second display D2 can be controlled by the processor 207 to include an indication of at least one, at least two, or all of the elements consumed to generate the flavored aerosol, such as the capsule remaining amount, the cartridge remaining amount, and the battery remaining amount.

[0060] The display mode shown in FIG. 5 is merely an example, and the display modes of the capsule remaining amount, the cartridge remaining amount, and the battery remaining amount may be other modes. For example, as in a1, b1, and c1 in FIG. 6, an icon display may be used that indicates only the presence or absence of the remaining amount of each of the multiple elements. As exemplified in a1, b1, and c1 in FIG. 6, the display mode of the second display D2 may include an indication that specifies which of two states is present for at least one of the multiple elements. The two states may be a first state indicating that the ability to generate a flavored aerosol is sufficient, and a second state indicating that the ability to generate a flavored aerosol is insufficient. In the examples of a1, b1, and c1 in FIG. 6, an icon without an "!" mark indicates the first state, and an icon with an "!" mark indicates the second state. a1 in FIG. 6 indicates that the capsule remaining amount and the cartridge remaining amount are in the first state, and the battery remaining amount is in the second state. b1 in FIG. 6 indicates that the capsule remaining amount, the cartridge remaining amount, and the battery remaining amount are in the first state. c1 in Fig. 6 indicates that the cartridge remaining amount is in the first state, and the capsule remaining amount and the battery remaining amount are in the second state. As exemplified by b1, b2, and b3 in Fig. 6, the display mode of the second display D2 may be one in which each remaining amount is shown as a numerical value.

[0061] An example of the operation of the power supply unit 102 or the inhaler 100 will be described with reference to Figs. 7 to 12. This operation is controlled by the processor 207. In an initial state, the power supply unit 102 is in standby in a sleep mode. In step S1, the processor 207 detects that the external power supply (charger) is V busThe processor 207 determines whether the power source 205 is connected to the port and charging has started, and if it is determined that charging has started, the process proceeds to step S8, and if not, the process proceeds to step S2. In step S2, the processor 207 determines whether a startup command has been generated by operating the action button B, and if it is determined that a startup command has been generated, the process proceeds to step S3, and if not, the process proceeds to step S4. For example, when a predetermined operation such as pressing the action button B repeatedly a predetermined number of times is performed, the processor 207 can determine that a startup command has been generated. In step S3, the processor 207 leaves the sleep mode and transitions to the active mode.

[0062] In step S4, the processor 207 determines whether the planned start-up timing has been reached, and if it is determined that the planned start-up timing has been reached, the process proceeds to step S5, otherwise the process returns to step S1. The planned start-up timing may be, for example, a predetermined regular timing (e.g., every hour, every two hours, every three hours, every 24 hours), or a preprogrammed timing (e.g., at midnight).

[0063] In step S5, the processor 207 leaves the sleep mode and transitions to the active mode. Next, in step S6, the processor 207 executes a rewrite subroutine #1, which is a process related to rewriting the display when replacing a cartridge or capsule, and then in step S7, the processor 207 transitions from the active mode to the sleep mode and returns the process to step S1.

[0064] If charging is detected in step S1, in step S8, the processor 207 leaves the sleep mode and transitions to the charging mode, and the processor 207 executes a rewrite subroutine #2, which is a process related to rewriting the display during charging. After that, in step S10, the processor 207 transitions from the charging mode to the sleep mode, and the process returns to step S1. Details of the rewrite subroutine #1 and the rewrite subroutine #2 will be described later.

[0065] In this way, the processor 207 transitions from the sleep mode to the active mode in response to a start command or a planned start timing, and executes a process (rewrite subroutine #1) for rewriting the display when replacing a cartridge or capsule. The processor 207 also transitions from the sleep mode to the charging mode in response to the start of charging, and executes a process (rewrite subroutine #2) for rewriting the display when charging.

[0066] Fig. 8 shows a control flow after the sleep mode is released and the active mode is entered in step S3. Although not shown, after the active mode is entered, the rewrite subroutine #1 may be repeatedly executed (e.g., periodically executed) at a planned timing in parallel with the following processing, and when charging is started, the rewrite subroutine #2 may be executed in response to the start of charging. When charging is started, the control flow shown in Fig. 8 may be forcibly ended.

[0067] From step S11 onwards, except when a cartridge replacement, a capsule replacement or charging is performed, the remaining amount of each of the multiple elements that can be displayed using display D2 (or at least one of display D2, first display D1 and third display D3; the same applies below) decreases. Therefore, in step S11, processor 207 obtains the remaining amounts of the multiple elements, i.e., the remaining battery amount, the remaining cartridge amount and the remaining capsule amount, and then in step S12, executes rewrite subroutine #3, which is a process for rewriting display D2 in accordance with the decrease in the remaining amount of each element.

[0068] In step S13, the processor 207 determines whether the remaining battery level is greater than a threshold. The threshold is, for example, a threshold for determining whether the remaining battery level allows operation in the active mode and the aerosol generation mode. More specifically, the threshold may be set as a lower limit of the remaining battery level that is predetermined such that even generation of aerosol corresponding to N puff operations (for example, N=1) is impossible. If the remaining battery level is equal to or less than the threshold, the processor 207 determines that operation in the active mode or the aerosol generation mode is impossible, transitions to the sleep mode in step S14, and the process returns to step S1.

[0069] If the remaining battery level is greater than the threshold, in step S15, the processor 207 waits for an aerosol generation request (atomization request). The aerosol generation request may be, for example, a notification or transmission of a puff detection from the puff sensor 209 to the processor 207. Alternatively, if an operation unit such as a switch or sensor (not shown) is provided for that purpose, the aerosol generation request may be generated by the user operating the operation unit. The aerosol generation request may also be generated by operating the action button B.

[0070] When the occurrence of an aerosol generation request is detected in step S15, the processor 207 starts supplying power to the heater 127 in step S16 (transitions to an aerosol generation mode). After that, in step S17, the processor 207 waits for the end of the aerosol generation request. When the aerosol generation request is ended, in step S18, the processor 207 stops supplying power to the heater 127 (transitions to an active mode).

[0071] If there is no aerosol generation request in step S15, in step S19, the processor 207 determines whether a predetermined time has elapsed since the sleep mode was left. If the predetermined time has elapsed since the sleep mode was left, the processor 207 returns to the sleep mode in step S20, and the process returns to step S1. If the predetermined time has not elapsed since the sleep mode was left, the processor 207 returns to the process in step S11. Alternatively, the processor 207 may return to the process in step S15.

[0072] FIG. 9 shows the control flow after the power supply to the heater 127 is stopped in step S18. In step S26, the processor 207 acquires the remaining amounts of a plurality of elements, i.e., the remaining battery amount, the remaining cartridge amount, and the remaining capsule amount, and then in step S27, executes a rewrite subroutine #3, which is a process for rewriting the display D2 in accordance with the decrease in the remaining amount of each element. The processor 207 can acquire the remaining battery amount, for example, by acquiring the output voltage of the power source 205, or the number of puffs after charging is completed. Alternatively, if the power source unit 102 includes a management circuit that manages the power source 205, the processor 207 can acquire the remaining battery amount based on the output from the management circuit. The processor 207 can acquire the remaining cartridge amount, for example, based on the number of puffs after the cartridge 104 is attached to the power source unit 102 or the holder 103, or based on the output of the sensor if a sensor for detecting the remaining amount is included. The processor 207 can obtain the remaining amount of capsule based on, for example, the number of puffs since the capsule 106 was attached to the power supply unit 102 or the holding portion 103, or, if a sensor for detecting the remaining amount is provided, based on the output of the sensor.

[0073] The cartridge 104 may have a function of providing identification information such as an RF-ID, in which case the processor 207 can manage the remaining cartridge amount of each cartridge 104 based on the identification information. Similarly, the capsule 106 may have a function of providing identification information such as an RF-ID, in which case the processor 207 can manage the remaining capsule amount of each capsule 106 based on the identification information.

[0074] In step S28, the processor 207 determines whether the remaining battery amount is greater than the first threshold. If it is determined that the remaining battery amount is greater than the first threshold, the process proceeds to step S29. In step S29, the processor 207 determines whether the remaining cartridge amount is greater than the second threshold. If it is determined that the remaining cartridge amount is greater than the second threshold, the process proceeds to step S30. In step S30, the processor 207 determines whether the remaining capsule amount is greater than the third threshold. If it is determined that the remaining capsule amount is greater than the third threshold, that is, if the remaining amounts of the multiple elements are greater than their respective thresholds, the process returns to step S11. In such a case, the process may return to step S15 instead of step S11.

[0075] If it is determined in step S28 that the remaining battery level is equal to or less than the first threshold, if it is determined in step S29 that the remaining cartridge level is equal to or less than the second threshold, or if it is determined in step S30 that the remaining capsule level is equal to or less than the third threshold, the process goes to the sleep mode in step S31, and the process returns to step S1. Here, if it is determined in step S28 that the remaining battery level is equal to or less than the first threshold, the processor 207 can use at least one of the displays D1, D2, D3, and the vibration generating unit V to notify the user of an alarm indicating that charging should be performed before going into the sleep mode. Also, if it is determined in step S29 that the remaining cartridge level is equal to or less than the second threshold, the processor 207 can use at least one of the displays D1, D2, D3, and the vibration generating unit V to notify the user of an alarm indicating that the cartridge 104 should be replaced before going into the sleep mode. Furthermore, if it is determined in step S30 that the remaining capsule amount is equal to or less than the third threshold value, the processor 207 can use at least one of the displays D1, D2, D3 and the vibration generating unit V to alert the user to the need to replace the capsule 106 before transitioning to sleep mode.

[0076] 10 shows the control flow of the rewrite subroutine #1 executed in step S6. In step S601, the processor 207 determines whether the capsule 106 has been removed from the power supply unit 102 or the holder 103, and if it is determined that the capsule 106 has been removed, the processor 207 advances the process to step S607, otherwise, the processor 207 advances the process to step S602. For example, if the sensor 222 is provided, the processor 207 can determine that the capsule 106 has been removed from the power supply unit 102 or the holder 103 based on the output of the sensor 222. Alternatively, if the removal and installation of the capsule 106 appears in a change in the output of the measurement circuit 210, the processor 207 can determine that the capsule 106 has been removed from the power supply unit 102 or the holder 103 based on the change in the output of the measurement circuit 210.

[0077] In step S602, the processor 207 determines whether the cartridge 104 has been removed from the power supply unit 102 or the holder 103, and if it is determined that the cartridge 104 has been removed, the process proceeds to step S603, and if not, the rewrite subroutine #1 is terminated. For example, if a sensor 221 is provided, the processor 207 can determine that the cartridge 104 has been removed from the power supply unit 102 or the holder 103 based on the output of the sensor 221. Alternatively, the processor 207 can determine that the cartridge 104 has been removed from the power supply unit 102 or the holder 103 based on a change in the output from the measurement circuit 210. Here, in a state in which the cartridge 104 is properly held by the holder 103, when the switch 201 is turned on, the output voltage of the voltage converter 202 is fed to the heater 127 and the shunt resistor R shuntand the voltage divided by this is supplied to the measurement circuit 210. On the other hand, in a state in which the cartridge 104 is removed from the power supply unit 102 or the holder 103, when the switch 201 is turned on, the output voltage of the voltage converter 202 is supplied to the measurement circuit 210. Therefore, when the cartridge 104 is removed from the power supply unit 102 or the holder 103, the signal supplied from the measurement circuit 210 to the processor 207 changes when the switch 201 is turned on.

[0078] In step S603, the processor 207 prohibits the supply of power to the heater 127. In a state in which the supply of power to the heater 127 is prohibited, power is not supplied to the heater 127 even if an aerosol generation request occurs.

[0079] In step S604, the processor 207 waits for the cartridge 104 to be attached to the power supply unit 102 or the holder 103. For example, if a sensor 221 is provided, the processor 207 can determine that the cartridge 104 has been attached to the power supply unit 102 or the holder 103 based on the output of the sensor 221. Alternatively, the processor 207 can determine that the cartridge 104 has been attached to the power supply unit 102 or the holder 103 based on a change in the output of the measurement circuit 210.

[0080] In step S605, the processor 207 rewrites the display of the cartridge remaining amount (remaining amount of the aerosol source in the cartridge 104) to a remaining amount corresponding to the replacement of the cartridge 104. Typically, the processor 207 rewrites the display of the second display D2 so that the new cartridge remaining amount is greater than the original cartridge remaining amount. In one example, the processor 207 may rewrite the display of the second display D2 so that the cartridge remaining amount is displayed as 100%. The power supply unit 102 may be provided with a remaining amount sensor that detects the remaining amount of the aerosol source in the cartridge 104, and in this case, the processor 207 may rewrite the display of the second display D2 so that the cartridge remaining amount corresponding to the output of the remaining amount sensor is displayed.

[0081] In step S606, the processor 207 releases the prohibition of the supply of power to the heater 127, and ends the rewrite subroutine #1. As a result, when an aerosol generation request occurs, power can be supplied to the heater 127 in response to the request.

[0082] When it is determined in step S601 that the capsule 106 has been removed from the power supply unit 102 or the holder 103, in step S607, the processor 207 prohibits the supply of power to the heater 127. In a state in which the supply of power to the heater 127 is prohibited, power is not supplied to the heater 127 even if an aerosol generation request is generated.

[0083] In step S608, the processor 207 waits for the capsule 106 to be attached to the power supply unit 102 or the holder 103. For example, if a sensor 222 is provided, the processor 207 can determine that the capsule 106 has been attached to the power supply unit 102 or the holder 103 based on the output of the sensor 222. Alternatively, if the removal and attachment of the capsule 106 is reflected in a change in the output of the measurement circuit 210, the processor 207 can determine that the capsule 106 has been attached to the power supply unit 102 or the holder 103 based on the change in the output of the measurement circuit 210.

[0084] In step S609, the processor 207 rewrites the display of the capsule remaining amount (the remaining amount of the flavoring substance in the capsule 106) to the remaining amount corresponding to the replacement of the capsule 106. Typically, the processor 207 rewrites the display of the second display D2 so that the new capsule remaining amount is greater than the original capsule remaining amount. In one example, the processor 207 may rewrite the display of the second display D2 so that the capsule remaining amount is displayed as 100%. The power supply unit 102 may be provided with a remaining amount sensor that detects the remaining amount of the flavoring substance in the capsule 106. In this case, the processor 207 may rewrite the display of the second display D2 so that the capsule remaining amount corresponding to the output of the remaining amount sensor is displayed.

[0085] In step S610, the processor 207 releases the prohibition of the supply of power to the heater 127, and ends the rewrite subroutine #1. As a result, when an aerosol generation request occurs, power can be supplied to the heater 127 in response to the request.

[0086] 11 shows a control flow of the rewrite subroutine #2 executed in step S9. In step S901, the processor 207 rewrites the display on the second display D2 so that a charging mark indicating that the power source 205 is being charged is displayed. In step S902, the processor 207 acquires the remaining battery level (the remaining amount of power that the power source 205 can discharge). The processor 207 can acquire the remaining battery level, for example, by acquiring the output voltage of the power source 205, or based on the number of puffs after charging is completed, or, if a management circuit for managing the power source 205 is provided, based on the output from the management circuit.

[0087] In step S903, the processor 207 rewrites the display on the second display D2 so that the remaining battery level acquired in step S902 is displayed. The remaining battery level may be displayed as a bar graph, as illustrated in FIG. 5. In step S904, the processor 207 determines whether charging of the power source 205 is completed based on the remaining battery level acquired in step S902, and if completed, the process proceeds to step S905, and if not, the process returns to step S902. In step S905, the processor 207 rewrites the display on the second display D2 so that the charging mark is erased, and ends the rewrite subroutine #2.

[0088] FIG. 12 shows a control flow of the rewrite subroutine #3 executed in steps S12 and S27. In step S121, the processor 207 determines whether the remaining battery level is below the first update threshold, and if the remaining battery level is below the first update threshold, the process proceeds to step S122, and if not, the process proceeds to step S123 (skips step S122). In step S122, the processor 207 rewrites the display of the second display (electronic paper display) D2 so that the remaining battery level according to the current remaining battery level (or the current first update threshold) acquired immediately before the rewrite subroutine #3 is executed is displayed. The remaining battery level may be displayed as a bar graph, as exemplified in FIG. 5. In step S122, the processor 207 may change the first update threshold from the current value to a smaller value. As a result, the remaining battery level may be displayed in multiple stages, as exemplified by the bar graph display in FIG. 5.

[0089] In step S123, the processor 207 determines whether the capsule remaining amount is below the second update threshold, and if the capsule remaining amount is below the second update threshold, the process proceeds to step S124, and if not, the process proceeds to step S125 (skip step S124). In step S124, the processor 207 rewrites the display of the second display D2 so that the capsule remaining amount according to the current capsule remaining amount (or the current second update threshold) obtained immediately before the rewrite subroutine #3 is executed is displayed. The capsule remaining amount may be displayed as a bar graph, as exemplified in FIG. 5. In step S124, the processor 207 may change the second update threshold from the current value to a smaller value. As a result, the capsule remaining amount may be displayed in multiple stages, as exemplified by the bar graph display in FIG. 5.

[0090] In step S125, the processor 207 determines whether the remaining amount in the cartridge is below the third update threshold, and if the remaining amount in the cartridge is below the third update threshold, the processor 207 proceeds to step S126, and if not, ends the rewrite subroutine #3 (skips step S126). In step S126, the processor 207 rewrites the display on the second display D2 so that the remaining amount in the cartridge is displayed according to the current remaining amount in the cartridge (or the current third update threshold) acquired immediately before the rewrite subroutine #3 is executed. The remaining amount in the cartridge may be displayed as a bar graph, as exemplified in FIG. 5. In step S126, the processor 207 may change the third update threshold from the current value to a smaller value. As a result, the remaining amount in the cartridge may be displayed in multiple stages, as exemplified by the bar graph display in FIG. 5.

[0091] In addition, when the remaining battery level is displayed in a bar graph format as illustrated in FIG. 5, the first update threshold may include a threshold value for the number of bars. In step S121, the processor 207 may compare the remaining battery level with a threshold value corresponding to the current remaining battery level among the threshold values ​​included in the first update threshold value. This is also the case when the remaining capsule level or the remaining cartridge level is displayed in a bar graph format. When the remaining battery level after full charge, the remaining capsule level after replacement, and the remaining cartridge level after replacement are sufficient and the bar graph display is sufficiently discrete (the number of bars in the bar graph display is sufficiently small), it will be understood that the frequency with which the processor 207 updates the display of the second display D2 in response to the occurrence of a factor that changes the remaining level of the aerosol source is smaller than the frequency of discharge from the power source 205 to the heater 127. In more detail, the remaining battery level after full charge, the remaining capsule level after replacement, and the remaining cartridge level after replacement may have an amount sufficient to perform power supply to the heater 127 in response to an aerosol generation request more than the number of bars in the bar graph display.

[0092] 13 shows a control flow of a modified example of the rewrite subroutine #3 executed in steps S12 and S27. In step S121, processor 207 determines whether the remaining battery level is below the first warning threshold, and if the remaining battery level is below the first warning threshold, proceeds to step S122, otherwise proceeds to step S123 (skips step S122). In step S122, processor 207 rewrites the display on second display (electronic paper display) D2 so as to display a warning indicating that the remaining battery level is insufficient or to prompt charging of power source 205.

[0093] In step S123, the processor 207 determines whether the remaining amount of capsules is below the second warning threshold, and if the remaining amount of capsules is below the second warning threshold, the process proceeds to step S124, otherwise the process proceeds to step S125 (skips step S124). In step S124, the processor 207 rewrites the display on the second display D2 so that a warning is displayed indicating that the remaining amount of capsules is insufficient or that the time to replace the capsules is approaching.

[0094] In step S125, the processor 207 determines whether the remaining amount in the cartridge is below the third warning threshold, and if the remaining amount in the cartridge is below the third warning threshold, the process proceeds to step S126, otherwise the rewrite subroutine #3 is terminated (step S126 is skipped). In step S126, the processor 207 rewrites the display on the second display D2 so that a warning is displayed indicating that the remaining amount in the cartridge is insufficient or that the time to replace the cartridge is approaching.

[0095] 7 to 12, the power supply unit 102 includes the action button B as an operation unit, and the processor 207 updates the source remaining amount display (display of cartridge remaining amount and capsule remaining amount) after the action button B is operated in step S2 to transition from sleep mode to active mode in step S3. Also, the processor 207 transitions from sleep mode to active mode at a planned timing in step S5, and checks replacement of the source (cartridge and capsule) in step S6, and updates the source remaining amount display if the source is replaced.

[0096] 14 shows an example of the configuration of an electrical component 110 having a function of detecting that the cartridge 104 has been replaced in the sleep mode. The output of the action button B is connected to an input terminal S of the processor 207 via a start signal line SS. The processor 207 can recognize a user's operation on the action button B based on a signal supplied from the action button B. When the action button B is pressed by the user, an active level signal (high active in this example configuration) is output from the action button B and is supplied to the input terminal S of the processor 207. When a predetermined operation is performed on the action button B in the sleep mode, the processor 207 (power supply unit 102) transitions to the active mode.

[0097] The predetermined operation may be, for example, an operation of repeatedly pressing the action button B a predetermined number of times (e.g., three times), or an operation of pressing and holding the action button B for a specified time (e.g., three seconds) or more. For example, when the action button B is pressed repeatedly a predetermined number of times (e.g., three times), a high-level signal may be supplied to the input terminal S for the predetermined number of times. Also, when the action button B is pressed and held for a specified time (e.g., three seconds) or more, a high-level signal may be supplied to the input terminal S for a specified time (e.g., three seconds) or more. When a predetermined operation is performed on the action button B in the sleep mode, the power supply unit 102 may transition from the sleep mode to the active mode.

[0098] The power supply unit 102 may include a detection circuit 230 that detects that the cartridge 104 has been replaced in the sleep mode. The detection circuit 230 may be configured to transition the signal level of the start signal line SS to a high level, which is an active level, when, for example, the cartridge 104 is replaced or the cartridge 104 is attached. The detection circuit 230 may include, for example, a transistor (PMOSFET) 231, a first inverter 232, and a second inverter 233. An input terminal of the first inverter 232 may be connected to the start signal line SS, and an output terminal of the first inverter 232 may be connected to a gate of the transistor 231. An input terminal of the second inverter 233 may be connected to a source of the transistor 231, and an output terminal of the second inverter 233 may be connected to the start signal line SS. A drain of the transistor 231 may be connected to an output of the measurement circuit 210.

[0099] When the cartridge 104 is properly attached to the power supply unit 102 or the holder 103, the measurement circuit 210 measures the resistance R HTR The measurement circuit 210 is configured so that this voltage falls within a predetermined range. Furthermore, when the cartridge 104 is removed from the power supply unit 102 or the holder 103, the measurement circuit 210 supplies a voltage greater than the upper limit of the predetermined range to the input terminal M of the processor 207. More specifically, when the cartridge 104 is properly attached to the power supply unit 102 or the holder 103, the measurement circuit 210 measures the output voltage of the voltage converter 202 across the heater 127 and the shunt resistor R shunt A voltage corresponding to the voltage divided by (in other words, the resistance value R of the heater 127) HTR The measurement circuit 210 supplies a voltage corresponding to the output voltage of the voltage converter 202 to the input terminal M of the processor 207. When the cartridge 104 is removed from the power supply unit 102 or the holder 103, the measurement circuit 210 supplies a voltage corresponding to the output voltage of the voltage converter 202 to the input terminal M of the processor 207. The output voltage of the voltage converter 202 is input to the heater 127 and the shunt resistor R shuntIt is clear that the voltage is greater than the voltage divided by

[0100] FIG. 15 shows a state in which the cartridge 104 is removed from the power supply unit 102 or the holding section 103 in the configuration example shown in FIG. 14. L and H in FIG. 15 indicate a low level and a high level, respectively. In a state in which the cartridge 104 is removed, a low level (L) that is an inactive level is supplied to the input terminal S of the processor 207. Specifically, a high level supplied from the measurement circuit 210 is supplied to the second inverter 233 via the body diode of the transistor 231, and the second inverter 233 supplies a low level, which is a logical inversion of the high level, to the input terminal S of the processor 207 via the start signal line SS. On the other hand, a high level, which is a voltage indicating that the cartridge 104 is removed from the power supply unit 102 or the holding section 103, is supplied to the input terminal M of the processor 207. Therefore, the processor 207 can detect that the cartridge is removed from the power supply unit 102 or the holding section 103 based on the voltages supplied to the input terminals S and M.

[0101] FIG. 16 shows a state in which the cartridge 104 is attached to the power supply unit 102 or the holder 103 in the configuration example shown in FIG. 14 (i.e., a state in which the cartridge 104 has been replaced). L and H in FIG. 16 indicate a low level and a high level, respectively. In a state in which the cartridge 104 is attached, a high level (H) that is an active level is input to the input terminal S of the processor 207. Specifically, a low level (however, not a ground level) supplied from the measurement circuit 210 is supplied to the second inverter 233 via the body diode of the transistor 231, and the second inverter 233 supplies a high level, which is a logical inversion of the low level, to the input terminal S of the processor 207 via the start signal line SS. Therefore, the processor 207 can detect that the cartridge 104 has been replaced in response to the transition of the signal supplied to the input terminal S from a low level to a high level when the cartridge 104 is removed. In this way, the input terminal S of the processor 207 is connected to a current path (including the voltage converter 202, the switch 201, the shunt resistor R shunt , heater 127) and an output signal of action button B are supplied to the processor 207. The processor 207 can detect a command to transition from the second mode to the first mode and replacement of the cartridge 104 based on a signal supplied to the input terminal S. Here, the voltage of the activation signal line SS can be reset to a low level by a reset circuit (not shown) that can be controlled by the processor 207 after the processor 207 recognizes or detects replacement of the cartridge 104.

[0102] FIG. 17 shows a control flow in the configuration example shown in FIG. 14. In the control flow in FIG. 17, steps S4 and S605 in the control flow in FIG. 7 are replaced with steps S4' and S605', respectively. Step S4' is executed in the sleep mode. In step S4', the processor 207 can detect that the cartridge 104 has been replaced in response to the signal supplied to the input terminal S changing from a low level to a high level when the cartridge 104 is removed, as described above. When the replacement of the cartridge 104 is detected in step S4', the processor 207 leaves the sleep mode in step S5 and changes to the active mode, then in step S605', executes the same process as in step S605 described above, and then changes to the sleep mode in step S7.

[0103] Specifically, in step S605', the processor 207 may rewrite the display of the second display (electronic paper display) D2 (source remaining amount display) of the cartridge remaining amount (remaining amount of the aerosol source of the atomizer 104) so ​​that the remaining amount is increased from the original display. In one example, the processor 207 may rewrite the display of the second display D2 so that the remaining amount of the cartridge is displayed as 100%. The power supply unit 102 may be equipped with a remaining amount sensor that detects the remaining amount of the aerosol source of the cartridge 104. In this case, the processor 207 may rewrite the display of the second display D2 so that the remaining amount of the cartridge is displayed according to the output of the remaining amount sensor.

[0104] As described above, in the configuration examples shown in Figs. 14 to 17, the display of the second display D2 includes a source remaining amount display regarding the remaining amount of the cartridge 104, which is the source of aerosol generation. Furthermore, in a sleep mode (second mode) in which power consumption is smaller than that in an active mode (first mode), when the cartridge 104 is replaced, the processor 207 may update the source remaining amount display. Furthermore, when the cartridge 104 is replaced in the second mode, the processor 207 may update the source remaining amount display after transitioning to the active mode. Thereafter, the processor 207 may transition to the sleep mode. Furthermore, the processor 207 may detect that the cartridge 104 has been removed from the holder 103 and then a new cartridge 104 has been attached to the holder 103 as replacement of the cartridge 104.

[0105] 14 to 17, the replacement of the capsule 106 is not detected, but the replacement of the capsule 106 can be detected, for example, based on the output of the sensor 222. In this case, the capsule remaining amount can be rewritten in the same manner as the rewriting of the display of the cartridge remaining amount in response to the cartridge replacement described with reference to FIG.

[0106] Furthermore, replacement of the cartridge 104 and replacement of the capsule 106 may be detected based on the output of the sensors 221, 222, thereby updating the indication of the remaining cartridge and capsule amounts.
