SUMMARY OF INVENTION

TECHNICAL PROBLEM

In configurations in which a control sequence is not transmitted to another aerosol-generating device when movement of the host device is detected, the control sequence cannot easily be transmitted to other aerosol-generating devices.
The objective of the present disclosure is to enable control sequences to be transmitted easily to other aerosol-generating devices.

SOLUTION TO PROBLEM

The present disclosure provides an aerosol-generating device comprising: a heating unit which heats a substrate containing an aerosol source by means of electrical supply from a power source, in accordance with a control sequence; a detecting unit which detects motion of the host device, and a control unit which, in a state in which a connection has been established between the host device and another aerosol-generating device, performs control to transmit the control sequence to the other aerosol-generating device if a first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device.
The heating unit may heat the substrate in accordance with any of a plurality of control sequences, and if the first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device, the control unit may perform control to transmit a specific control sequence among the plurality of control sequences to the other aerosol-generating device. In this case, the control unit may perform control to select the specific control sequence in accordance with a predetermined order of the plurality of control sequences. Furthermore, the control unit may perform control to select the specific control sequence in accordance with the type of the first motion detected by the detecting unit of the host device or the detecting unit of the other aerosol-generating device.
The control unit may be configured such that, if the first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device, the control unit performs control to receive the control sequence from the other aerosol-generating device that transmitted the control sequence. In this case, the control unit may perform control such that after the heating unit has heated the substrate once in accordance with the control sequence received from the other aerosol-generating device, the heating unit cannot heat the substrate in accordance with said control sequence. In this case, the aerosol-generating device may comprise a first memory unit which stores a control sequence to be used two or more times for heating by the heating unit, and a second memory unit which stores a control sequence to be used only once for heating by the heating unit, wherein the control unit performs control to store the control sequence received from the other aerosol-generating device by overwriting the control sequence stored in the second memory unit.
The aerosol-generating device may additionally comprise an opening and closing portion which opens or closes an opening through which the substrate is inserted, wherein, if the opening is opened by the opening and closing portion, the control unit performs control such that the control sequence is not transmitted to the other aerosol-generating device even if the first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device.
The control unit may be configured such that, if a second motion is detected by the detecting unit of the host device and the detecting unit of another aerosol-generating device, the control unit performs control to establish a connection with the other aerosol-generating device. In this case, the first motion and the second motion may be the same type of motion. Furthermore, the aerosol-generating device may additionally comprise an opening and closing portion which opens or closes an opening through which the substrate is inserted, wherein, if the opening is opened by the opening and closing portion, the control unit performs control such that a connection is not established with the other aerosol-generating device even if the second motion is detected by the detecting unit of the host device and the detecting unit of the other aerosol-generating device.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present disclosure, control sequences can easily be transmitted to other aerosol-generating devices.

DESCRIPTION OF EMBODIMENTS

Embodiments of the present disclosure will be described in detail below with reference to the appended drawings. An aerosol-generating device according to the embodiments is a form of electronic cigarette. A substance generated by the aerosol-generating device is an aerosol. An aerosol is a mixture of minute liquid or solid particles suspended in a gas, and air or another gas. The embodiments describe aerosol-generating devices which generate the aerosol without associated burning. Furthermore, the embodiments describe aerosol-generating devices to which a solid aerosol source can be fitted.

An example of the external appearance of an aerosol-generating device used in Embodiment 1 will first be described.
Fig. 1 is a diagram in which a front face side of an aerosol-generating device 1 is viewed from diagonally above.
Fig. 2 is a diagram in which an upper face of the aerosol-generating device 1 is viewed from above.
The aerosol-generating device 1 is configured by a main body device 10, and a slide cover 20 which can be slidably operated along an upper face of the main body device 10. It should be noted that, for convenience of description, fig. 1 shows a state in which the slide cover 20 has been removed from the upper face of the main body device 10.
In the present embodiment, the face on which a power button 11 is provided will be referred to as a "front face".
Furthermore, the face on which an insertion port into which a stick-type substrate is inserted (referred to below as a "stick-type substrate insertion port") 13 is provided will be referred to as an "upper face".
Moreover, the face on the opposite side to the upper face will be referred to as the "bottom face", and the other three faces will be referred to as "side faces".
An LED lamp 12 is provided on the front face of the main body device 10, in addition to the power button 11.
A USB (= universal serial bus) cable insertion port 14 is provided on the upper face of the main body device 10, in addition to the stick-type substrate insertion port 13.
The power button 11 is used for instructing the start of heating of the stick-type substrate, for resets, and for instructing Bluetooth (registered trademark) pairing, for example. A reset is performed by a long press (e.g., a press of 5 seconds or more) on the power button 11. BLE (= Bluetooth low energy) is used as Bluetooth in the present embodiment.
The LED lamp 12 is used to notify operating states of the main body device 10, and remaining capacity of a secondary battery, for example. In the present embodiment, a surface of the LED lamp 12 is covered by a light-transmitting material, which enables a user to observe a state of illumination of the LED lamp 12.
Operating states include a state of progress of a heating cycle, a state of progress of charging, and errors, for example.
When the state of progress of the heating cycle is being notified, the length of the illuminated part of the LED lamp 12 indicates the remaining usable time. Moreover, the LED lamp 12 flashes slowly when there is little remaining time.
When the state of progress of charging is being notified, the LED lamp 12 flashes during charging, and the length of the flashing part of the LED lamp 12 increases as the amount of stored electricity increases due to charging. Moreover, when charging is complete, the LED lamp 12 turns off or stays in an illuminated state.
When the remaining capacity of the secondary battery is being displayed, the battery remaining capacity is displayed by the length of the illuminated part of the LED lamp 12 at the point in time when the slide cover 20 is opened or at the point in time when the slide cover 20 is closed, for example.
Moreover, the LED lamp 12 flashes when the secondary battery has little remaining capacity. Furthermore, the LED lamp 12 flashes rapidly in a state in which the remaining capacity of the secondary battery will not allow even one unused stick-type substrate to be smoked.
The slide cover 20 is dimensioned to cover approximately half of the upper face. The slide cover 20 operated to the open state completely conceals the USB cable insertion port 14, and the slide cover 20 operated to the closed state completely conceals the stick-type substrate insertion port 13. That is to say, the slide cover 20 has the role of alternately concealing either one of the stick-type substrate insertion port 13 and the USB cable insertion port 14. Fig. 2 shows a state in which the slide cover 20 has been operated to the open state. The stick-shaped substrate insertion port 13 is an example of an opening through which the substrate is inserted, and the slide cover 20 is an example of an opening and closing portion which opens or closes the opening.
The stick-type substrate used in the present embodiment accommodates a solid aerosol source in a paper tube molded substantially into a cylindrical shape. The shape of the stick-type substrate insertion port 13 is therefore depicted in both fig. 1 and fig. 2 by a circular shape which is generally the same shape as a stick-type substrate. The diameter of an opening part of the stick-type substrate insertion port 13 constitutes the dimension of a stick-type substrate which can be inserted. In other words, the diameter of the stick-type substrate is a dimension that enables the stick-type substrate to be inserted into the stick-type substrate insertion port 13.
The USB cable insertion port 14 is compatible with type C in the present embodiment. However, this does not mean that the shape of the terminal used for charging the secondary battery is limited to type C, or limited to USB. The terminal for a power source cable used for charging the secondary battery may be of another type.
A magnet, for example, is attached to a rear face of the slide cover 20. Meanwhile, a Hall IC is attached to the main body device 10 in a movable range of the slide cover 20.
The Hall IC is a magnetic sensor formed by a Hall element and an operational amplifier, etc., and outputs a voltage commensurate with the intensity of a magnetic field passing across the Hall element.
In the present embodiment, opening and closing of the slide cover 20 is sensed from a change in the voltage output from the Hall IC accompanying sliding of the slide cover 20. That is to say, it is sensed whether the slide cover 20 is at the closed position or the open position.
The aerosol-generating device 1 of the present embodiment is sized to be capable of being held by a user in a single hand.
Various types of electronic components required for generating the aerosol are built into the main body device 10. In this sense, the main body device 10 is an example of an electronic device specifically for generating an aerosol. Moreover, in a narrow sense the main body device 10 is referred to as an aerosol-generating device.

Fig. 3 is a diagram schematically illustrating the internal configuration of the main body device 10. It should be noted that fig. 3 depicts a state in which the stick-type substrate 30 has been fitted into the main body device 10. Furthermore, the internal configuration shown in fig. 3 is intended to illustrate the components provided in the main body device 10 and positional relationships thereof. For this reason, the external appearance of the components, etc. illustrated in fig. 3 does not necessarily match the external appearance diagrams discussed hereinabove.
The main body device 10 is configured by a power source unit 101, a sensor unit 102, a notification unit 103, a memory unit 104, a communication unit 105, a control unit 106, a heating unit 107, a heat insulating portion 108, and a holding portion 109.
As discussed hereinabove, fig. 3 depicts a state in which the stick-type substrate 30 is being held in the holding portion 109. The aerosol is inhaled by the user in this state.
The power source unit 101 is a unit for supplying power to each unit. The power source unit 101 stores power in a secondary battery, for example. A lithium ion secondary battery is used in the present embodiment.
The secondary battery can be charged from an external power source. In the present embodiment, the external power source is assumed to be a mains power source or a mobile battery, for example.
The sensor unit 102 is an electronic component for detecting various types of information relating to the main body device 10.
The sensor unit 102 includes a pressure sensor such as a microphone capacitor, or a flow rate sensor, for example. The sensor unit 102 outputs detected information to the control unit 106. For example, when a change in air pressure or a flow of air accompanying inhalation has been detected, the sensor unit 102 outputs a numerical value representing inhalation of the aerosol by the user to the control unit 106.
The sensor unit 102 is provided in conjunction with a button or switch used for receiving user operations, for example. The button as referred to here includes the power button 11 (see fig. 1) discussed hereinabove. Furthermore, the switch includes the slide cover 20 (see fig. 2) discussed hereinabove.
If an operation by the user is sensed, the sensor 102 outputs the sensing of the operation to the control unit 106.
The sensor unit 102 additionally includes a temperature sensor for detecting the temperature of the heating unit 107. The temperature sensor detects the temperature of the heating unit 107 on the basis of an electrical resistance value of a conductive track of the heating unit 107, for example. The detected electrical resistance value is output from the sensor unit 102 to the control unit 106. It should be noted that the control unit 106 calculates the temperature of the heating unit 107 on the basis of the electrical resistance value. In other words, the control unit 106 calculates the temperature of the stick-type substrate 30 which is held in the holding portion 109.
Furthermore, the sensor unit 102 includes a motion sensor that senses a user operation by detecting motion of the main body device 10. The motion sensor may include an acceleration sensor for detecting acceleration of the main body device 10. A capacitive acceleration sensor comprising a fixed electrode and a movable electrode formed from silicon, and a sensor element configured by a spring or the like is illustrated as an example of the acceleration sensor. The acceleration sensor may equally be a piezoresistance or heat-detection type acceleration sensor. Alternatively, the motion sensor may comprise a gyro sensor that detects the angular velocity of the main body device 10. In this case, the sensor unit 102 is an example of a detecting unit which detects motion of the host device.
It should be noted that the timing at which the motion sensor is powered on may be the same as the timing of at which the control unit 106 is powered on. More specifically, since the control unit 106 is powered on when the user cancels a shipment mode of the aerosol-generating device 1 and starts using the aerosol-generating device 1, it is preferable that the motion sensor is also powered on at this time. Also, since the control unit 106 is powered on even during a sleep mode, the motion sensor is capable of sensing even during the sleep mode.
The notification unit 103 is an electronic component for notifying the user of various types of information relating to the main body device 10. The notification unit 103 includes the LED lamp 12 (see fig. 1), for example. When the power source unit 101 needs to be charged, when the power source unit 101 is in the process of being charged, or when there is an abnormality in the main body device 10, the LED lamp 12 emits light with a different pattern in each case.
The patterns as referred to here include different colors and different timings for illumination/extinguishing, etc. Furthermore, the LED lamp 12 includes a plurality of LEDs. It should be noted that the LED lamp 12 is an example of a light-emitting device and the LEDs are examples of light-emitting elements.
The notification unit 103 may also include another device which is used together with the light-emitting device or is used instead of the light-emitting device. Devices of this type include display devices for displaying text, images and other information, sound output devices for outputting sound, and vibration devices for causing the main body device 10 to vibrate, etc.
The light-emitting device, display device, sound output device and vibration device, etc. are examples of notification units for notifying information.
The notification unit 103 may additionally notify the user that a state in which the aerosol can be inhaled has been achieved. This notification indicates a state in which the temperature of the stick-type substrate 30 heated by means of the heating unit 107 has reached a predetermined temperature.
The memory unit 104 stores various types of information relating to operation of the main body device 10. The memory unit 104 is configured by a non-volatile storage medium such as a flash memory, for example.
Information stored in the memory unit 104 includes an OS (= operating system) and FW (= firmware), and other programs, for example.
Furthermore, the information stored in the memory unit 104 includes information relating to control of electronic components, for example. Information relating to control includes information relating to: remaining capacity and SOH (= state of health) of the secondary battery, and inhalation by the user, such as number of inhalations, times at which inhalation has occurred, and cumulative inhalation time.
The communication unit 105 is a communication interface for implementing communication between the main body device 10 and other devices. The communication unit 105 communicates with other devices by means of a system based on any wired or wireless communication standard. Examples of communication standards as referred to here include wireless LAN (= local area network), serial signal line, Wi-Fi (registered trademark), and Bluetooth (registered trademark).
For example, the communication unit 105 sends the information relating to user inhalation to a smartphone. Furthermore, the communication unit 105 downloads, from a server, update programs and heating profiles defining changes in the temperature of the heating unit 107 in a heating mode.
The control unit 106 functions as an arithmetic processing device and a control device, and controls operations of the main body device 10 in accordance with various programs.
Control signals are sent through signal lines different from a power source line. For example, communication in the main body device 10 employs a serial communication method such as an I2C (= inter-integrated circuit) communication method, an SPI (= serial peripheral interface) communication method, or a UART (= universal asynchronous receiver transmitter) communication method.
The control unit 106 is realized by means of an electronic circuit such as a CPU (= central processing unit), an MCU (= microcontroller unit), an MPU (= microprocessing unit), a GPU (= graphical processing unit), an ASIC (= application-specific integrated circuit), an FPGA (= field programmable gate array), or a DPS (= digital signal processor), for example.
The control unit 106 may also include a ROM (= read only memory) for storing programs and computation parameters, etc., and a RAM (= random access memory) for temporarily storing suitably changing parameters, etc.
The control unit 106 executes various types of processing and control through execution of programs.
The processing and control referred to here include, for example: supply of electricity by the power source unit 101; charging of the power source unit 101; detection of information by the sensor unit 102; notification of information employing the notification unit 103; writing of information to the memory unit 104 or reading of information from the memory unit 104; and sending/receiving of information employing the communication unit 105.
The control unit 106 additionally controls processing, etc. based on input of information to the electronic components and information output from the electronic components.
The holding portion 109 is a substantially cylindrical container. In the present embodiment, a space inside the holding portion 109 defined by an inner wall and a bottom face will be referred to as an internal space 109A. The internal space 109A is substantially columnar.
An opening 109B allowing the internal space 109A to communicate with the exterior is provided in the holding portion 109. The stick-type substrate 30 is inserted into the internal space 109A from the opening 109B. The opening 109B as referred to here corresponds to the stick-type substrate insertion port 13 in fig. 1. The stick-type substrate 30 is inserted until a tip end thereof touches a bottom portion 109C.
The stick-type substrate 30 is only partially accommodated in the internal space 109A. A state in which the stick-type substrate 30 is accommodated in the internal space 109A will be referred to as the stick-type substrate 30 being held in the internal space 109A.
The inner diameter of at least part of the holding portion 109 in an axial direction thereof is formed so as to be smaller than the outer diameter of the stick-type substrate 30.
An outer circumferential surface of the stick-type substrate 30 inserted into the internal space 109A is therefore subjected to pressure from the inner wall of the holding portion 109. The stick-type substrate 30 is held in the internal space 109A by means of this pressure.
The holding portion 109 also has a function of defining a flow path for air passing through the stick-type substrate 30. An air inflow hole, which is an inlet for air into the flow path, is disposed in the bottom portion 109C, for example. Moreover, the opening 109B serves as an air outflow hole, which is an outlet for the air.
In the present embodiment, only part of the stick-type substrate 30 is held in the holding portion 109, with the remainder protruding outside from an enclosure. The part which is held in the holding portion 109 will be referred to below as a substrate portion 30A, and the part protruding from the enclosure will be referred to below as a mouthpiece portion 30B.
The aerosol source is accommodated in at least the substrate portion 30A. The aerosol source is a substance which is atomized by heating so as to generate an aerosol.
The aerosol source includes shredded tobacco, and also processed products obtained by molding a tobacco raw material into a granular form, a sheet form or a powder form, or other tobacco-derived substances.
In addition, the aerosol source may also include non-tobacco-derived substances produced from plants other than tobacco, such as mint or herb. The aerosol source may include a flavoring component such as menthol, for example.
When the main body device 10 is a medical inhaler, the aerosol source may include a drug to be inhaled by a patient. It should be noted that the aerosol source is not limited to a solid, and may equally be a polyhydric alcohol such as glycerol or propylene glycol, or may be a liquid such as water, for example.
At least part of the mouthpiece portion 30B is held in the user's mouth during inhalation.
When the user inhales with the mouthpiece portion 30B held in their mouth, air flows into the internal space 109A from the air inflow hole. The air that has flowed in reaches the user's mouth after passing through the internal space 109A and the substrate portion 30A. The air reaching the user's mouth contains the aerosol generated by the substrate portion 30A.
The heating unit 107 is formed by a heater or other heat-generating element. The heating unit 107 is formed by any material such as a metal or polyimide. The heating unit 107 is constructed in the form of a film, for example, and is fitted to the outer circumferential surface of the holding portion 109.
The aerosol source contained in the stick-type substrate 30 is heated and atomized by the heat generated by the heating unit 107. The atomized aerosol source is mixed with air, etc., and an aerosol is generated.
In fig. 3, the outer circumferential region of the stick-type substrate 30 is initially heated, with the range of heating steadily moving toward the center.
Atomization of the aerosol source therefore starts from the outer circumferential region of the stick-type substrate 30 and steadily moves toward the center.
The heating unit 107 generates heat by means of electrical supply from the power source unit 101. Electrical supply to the heating unit 107 is permitted when a predetermined user operation has been sensed by means of the sensor unit 102, for example. The predetermined user operation as referred to here includes operation of the slide cover 20 (see fig. 2) and/or of the power button 11 (see fig. 1).
The heating unit 107 heats the stick-shaped substrate 30, which is the aerosol source, in accordance with a heating profile stored in the memory unit 104. The heating profile is a data file defining a change over time in a target temperature after the start of heating. The heating profile is an example of a control sequence that defines the heating. Therefore, the heating unit 107 is an example of a heating unit which heats a substrate containing an aerosol source by means of electrical supply from a power source, in accordance with a control sequence. Furthermore, a plurality of heating profiles may be stored in the memory unit 104. Therefore, the heating unit 107 is an example of a heating unit which heats the substrate in accordance with any of a plurality of control sequences.
Moreover, inhalation by the user becomes possible when the temperature of the stick-type substrate 30 heated by means of the heating unit 107 reaches a predetermined temperature. Inhalation of the aerosol by the user is sensed by means of the flow rate sensor, etc. in the sensor unit 102 and is saved in the memory unit 104.
Electrical supply to the heating unit 107 is stopped when a predetermined user operation is subsequently sensed. The predetermined user operation includes an operation to close the slide cover 20.
It should be noted that, even if the predetermined user operation is not sensed, electrical supply to the heating unit 107 is stopped when a heating time defined in the heating profile has expired.
It is additionally possible to adopt a method in which electricity is supplied to the heating unit 107 while inhalation by the user is sensed, and electrical supply to the heating unit 107 is stopped when inhalation by the user is no longer sensed.
Furthermore, in the example of fig. 3, the heating unit 107 is disposed at the outer circumferential portion of the stick-type substrate 30, but it is equally possible for the heating unit 107 to be a blade-like metal piece which is inserted into the stick-type substrate 30, or for the heating unit 107 to be a metal piece built into the stick-type substrate 30. When a metal piece acting as the heating unit 107 is built into the stick-type substrate 30, an induction heating coil should be arranged around the holding portion 109.
The heat insulating portion 108 is a member for reducing propagation of heat generated by the heating unit 107 to the surrounding area. The heat insulating portion 108 is therefore disposed so as to cover at least the outer circumferential surface of the heating unit 107.
For example, the heat insulating portion 108 is configured by a vacuum insulating material or an aerogel insulating material, etc. A vacuum insulating material is a heat insulating material in which a state of high vacuum is created by wrapping glass wool and silica (silicon powder), etc. in a resin film, for example, so that heat conduction by gas is as close as possible to zero.

Sensing of a user operation by the sensor unit 102 will now be described. It should be noted that in the present embodiment, a double-tap operation on the aerosol-generating device 1 and a shake operation on the aerosol-generating device 1 will be described, as examples of user operations.
Fig. 4 is a diagram illustrating a method for sensing a double-tap operation by means of the sensor unit 102. The sensor unit 102 senses a double-tap operation by detecting acceleration of the aerosol-generating device 1 and performing the following processing on the basis of this acceleration.

(1) A period T11 starts when the acceleration exceeds an upper limit threshold Th1 or falls below a lower limit threshold (-Th1).
(2) If the acceleration exceeds the upper limit threshold Th1 in (1), a first tap is sensed if the acceleration falls below the upper limit threshold Th1 within the period T11, and if the acceleration falls below the lower limit threshold (-Th1) in (1), the first tap is sensed if the acceleration exceeds the lower limit threshold (-Th1) within the period T11. In the drawing, the first tap is sensed at point P11.
(3) A period T12 starts after the first tap is sensed. In other words, processing similar to that for preventing chatter is performed during a period in which no tap is sensed.
(4) A period T13 starts from the moment the period T12 ends.
(5) A second tap is sensed if the tap detection in (1) and (2) occurs again within the period T13. In the drawing, the second tap is sensed at point P12. A double-tap operation is thereby sensed.

Fig. 5 is a diagram illustrating a method for sensing a shake operation by means of the sensor unit 102. The sensor unit 102 senses a shake operation by detecting acceleration of the aerosol-generating device 1 and performing the following processing on the basis of this acceleration.

(1) Counting for a period T2 starts when the acceleration exceeds a threshold Th2.
(2) Counting for the period T2 starts again if the acceleration falls below the threshold Th2 within the period T2.
(3) A shake operation is sensed if the acceleration exceeds the threshold Th2 within the period T2.

It should be noted that the control unit 106 only needs to pass the acceleration threshold information and detection period information to the sensor unit 102, and the processing for detecting the user operations illustrated in fig. 4 and fig. 5 is assumed to be completed within the sensor unit 102.
Furthermore, if the sensor unit 102 erroneously senses the user operation, the heating profile may be transmitted or received at a timing not intended by the user, and therefore a mechanism for preventing erroneous sensing is required.
As a mechanism for preventing such erroneous sensing, it is conceivable, for example, to collect threshold data for the double-tap operation and the shake operation, etc., for a certain number of users, and adopt this threshold data in the sensor unit 102 of all aerosol-generating devices 1 of a particular model. Moreover, the configuration may be such that the threshold data are not adjusted for each user if the model of the aerosol-generating device 1 being used is the same, or such that the threshold data are adjusted for each user even though the model of the aerosol-generating device 1 being used is the same.

The transmission and reception of heating profiles between aerosol-generating devices 1 will now be described. In the following description, the aerosol-generating device 1 transmitting the heating profile will be referred to an aerosol-generating device 1a and the aerosol-generating device 1 receiving the heating profile will be referred to as an aerosol-generating device 1b.
First, a method for selecting a heating profile to be transmitted in the aerosol-generating device 1a will be described.
Fig. 6 is a diagram illustrating a first method for selecting a heating profile. In the first selection method, when the user performs a predetermined operation, the aerosol-generating device 1a selects a heating profile stored in the memory unit 104 in accordance with a predetermined order. Here, the predetermined operation will be described taking the double-tap operation on the aerosol-generating device 1a as an example, but is not limited to this. The predetermined operation may be a shake operation on the aerosol-generating device 1a, etc. Alternatively, if a P2P (peer-to-peer) connection is established between the aerosol-generating device 1a and the aerosol-generating device 1b, the predetermined operation may be the same operation performed on the aerosol-generating device 1b.
In the drawing, in the initial state it is assumed that heating profile No. 1 is selected as the heating profile to be transmitted. In this state, if the user performs a double-tap operation on the aerosol-generating device 1a, the control unit 106 selects heating profile No. 2 as the heating profile to be transmitted. If the user then performs a double-tap operation on the aerosol-generating device 1a, the control unit 106 selects heating profile No. 3 as the heating profile to be transmitted. If the user then performs a double-tap operation on the aerosol-generating device 1a, the control unit 106 selects heating profile No. 4 as the heating profile to be transmitted. Moreover, if the user then performs a double-tap operation on the aerosol-generating device 1a, the control unit 106 returns to heating profile No. 1 as the heating profile to be transmitted.
In this case, the control unit 106 of the aerosol-generating device 1a is an example of a control unit that performs control to select a specific control sequence in accordance with a predetermined order of a plurality of control sequences.
Here, the configuration may be such that, by connecting the aerosol-generating device 1a to a smartphone, the order of the heating profiles can be changed via an application on the smartphone. However, even if the order of the heating profiles can be changed in this way, the number of double-tap operations required until the intended heating profile is selected may increase. For example, in fig. 6, if the user wishes to select heating profile No. 4 in a state in which heating profile No. 1 is set, and if neither of heating profiles No. 2 and No. 3 has been stored, a single double-tap on the aerosol-generating device 1a is sufficient. However, if heating profiles No. 2 and No. 3 have both been stored, the aerosol-generating device 1a needs to be double-tapped three times. Accordingly, a second method for selecting a heating profile, which does not require a large number of predetermined operations before the intended heating profile is selected, can be considered.
Fig. 7 is a diagram illustrating the second method for selecting a heating profile. In the second selection method, when the user performs an operation, the aerosol-generating device 1a selects a heating profile stored in the memory unit 104 in accordance with the type of the operation. Here, the operation will be described taking a combined operation of the double-tap operation and the shake operation on the aerosol-generating device 1a as an example, but is not limited to this. The operation may be a single operation comprising any one of a double-tap operation, a shake operation or another operation, or may be a combined operation of any two or more of said operations. Alternatively, if a P2P connection is established between the aerosol-generating device 1a and the aerosol-generating device 1b, the operation may be any of the same operations performed on the aerosol-generating device 1b.
In the drawing, in the initial state it is assumed that heating profile No. 1 is selected as the heating profile to be transmitted. In this state, if the user performs a double-tap operation followed by a shake operation on the aerosol-generating device 1a, the control unit 106 selects heating profile No. 2 as the heating profile to be transmitted. Further, if the user performs a shake operation followed by a double-tap operation on the aerosol-generating device 1a, the control unit 106 selects heating profile No. 3 as the heating profile to be transmitted. Furthermore, if the user performs a double-tap operation twice in succession on the aerosol-generating device 1a, the control unit 106 selects heating profile No. 4 as the heating profile to be transmitted. Moreover, in order to return again from the currently selected heating profile to heating profile No. 1, the operation performed to select the currently selected heating profile should be performed again, for example.
In this case, the aerosol-generating device 1a is an example of a host device, and the aerosol-generating device 1b is an example of another aerosol-generating device. In addition, the control unit 106 of the aerosol-generating device 1a is an example of a control unit that performs control to select a specific control sequence in accordance with the type of a first motion detected by the detecting unit of the host device or the detecting unit of the other aerosol-generating device.
It should be noted that in the aerosol-generating device 1a, the control unit 106 may be configured not to switch the heating profile when the slide cover 20 is open. This is because if the slide cover 20 is open, it is assumed that heating is being performed in accordance with a heating profile.
In this case, the control unit 106 of the aerosol-generating device 1a is an example of a control unit that performs control such that the control sequence is not switched when the opening of the opening and closing unit is open, even if a first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device.
Furthermore, in the aerosol-generating device 1a, the control unit 06 may be configured such that the heating profile is not transmitted to the aerosol-generating device 1b when BLE communication is in progress. This is because if the aerosol-generating device 1a is performing BLE communication, it is assumed that a heating profile is being transmitted or received.
Transmission and reception of heating profiles between the aerosol-generating device 1a and the aerosol-generating device 1b will next be described.
Fig. 8 is a diagram illustrating transmission and reception of a heating profile. In the drawing, it is assumed that a P2P connection has already been established between the aerosol-generating device 1a and the aerosol-generating device 1b. In this state, when the user performs a predetermined operation, the control unit 106 of the aerosol-generating device 1a transmits a heating profile to the aerosol-generating device 1b. The heating profile to be transmitted may be one selected from among a plurality of heating profiles using the selection method shown in fig. 6 or fig. 7. Here, the predetermined operation is exemplified by the user of the aerosol-generating device 1a performing a shake operation on the aerosol-generating device 1a, but is not limited to this. The predetermined operation may equally be a double-tap operation, for example, on the aerosol-generating device 1a by the user of the aerosol-generating device 1a, or a shake operation or a double-tap operation, for example, on the aerosol-generating device 1b by the user of the aerosol-generating device 1b.
In this case, the aerosol-generating device 1a is an example of a host device, the aerosol-generating device 1b is an example of another aerosol-generating device, and the motion of the aerosol-generating device 1a or the aerosol-generating device 1b due to the predetermined operation of the user is an example of a first motion. Also, the control unit 106 of the aerosol-generating device 1a is an example of a control unit which, in a state in which a connection has been established between the host device and another aerosol-generating device, performs control to transmit the control sequence to the other aerosol-generating device if a first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device. Furthermore, the control unit 106 of the aerosol-generating device 1a is an example of a control unit which, if the first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device, performs control to transmit a specific control sequence among a plurality of control sequences to the other aerosol-generating device.
Moreover, when a heating profile is selected, the notification unit 103 may notify information specifying the selected heating profile. For example, if the notification unit 103 is a vibrating device, notification of the information specifying the selected heating profile may be performed by causing the main body device 10 to vibrate a number of times corresponding to the selected heating profile number. Alternatively, if the notification unit 103 is the LED lamp 12, notification of the information specifying the selected heating profile may be performed by turning on the number of LEDs corresponding to the selected heating profile number.
Furthermore, in the aerosol-generating device 1a, the control unit 106 may be configured such that the heating profile is not transmitted to the aerosol-generating device 1b when the slide cover 20 is open. This is because if the slide cover 20 is open, it is assumed that heating is being performed in accordance with a heating profile.
In this case, the control unit 106 of the aerosol-generating device 1a is an example of a control unit that performs control such that the control sequence is not transmitted to the other aerosol-generating device when the opening of the opening and closing unit is open, even if a first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device.
Furthermore, in the aerosol-generating device 1a, the control unit 06 may be configured such that the heating profile is not transmitted to the aerosol-generating device 1b when BLE communication is in progress. This is because if BLE communication is in progress, it is assumed that a heating profile is being transmitted or received.
Meanwhile, when the heating profile is transmitted from the aerosol-generating device 1a as a result of the user performing the predetermined operation, the control unit 106 of the aerosol-generating device 1b receives the heating profile.
In this case, the aerosol-generating device 1b is an example of a host device, and the aerosol-generating device 1a is an example of another aerosol-generating device. Also, the control unit 106 of the aerosol-generating device 1b is an example of a control unit which, if a first motion is detected by the detecting unit of the host device or the first motion is detected by the detecting unit of the other aerosol-generating device, performs control to receive the control sequence from the other aerosol-generating device that transmitted the control sequence.
Storage of heating profiles in the aerosol-generating device 1b will next be described.
Fig. 9 is a diagram illustrating a method for storing heating profiles. As illustrated in the drawing, the memory unit 104 of the aerosol-generating device 1b comprises a first memory unit 1041 and a second memory unit 1042.
The first memory unit 1041 stores heating profiles other than a heating profile received from another aerosol-generating device 1. Such heating profiles include heating profiles stored at the time of shipment of the aerosol-generating device 1b, and heating profiles downloaded from a server, smartphone, etc. after shipment of the aerosol-generating device 1b, for example. Such heating profiles can be used any number of times for heating by the heating unit 107. In the drawing, heating profiles No. 1 to No. 4 are shown as the heating profiles stored in the first memory unit 1041. The first memory unit 1041 is an example of a first memory unit which stores a control sequence to be used two or more times for heating by the heating unit.
The second memory unit 1042 stores a heating profile received from another aerosol-generating device 1. Such a heating profile can only be used once for heating by the heating unit 107. That is, in the aerosol-generating device 1b, the control unit 106 is configured such that after a stick substrate 30 has been heated once using the heating profile stored in the second memory unit 1042, the stick substrate 30 cannot be heated again using said heating profile. In this case, the control unit 106 may store the heating profile received from the aerosol-generating device 1a by overwriting the heating profile stored in the second memory unit 1042. In the drawing, heating profile No. 5 is shown as the heating profile stored in the second memory unit 1042. The second memory unit 1042 is an example of a second memory unit which stores a control sequence to be used only once for heating by the heating unit. Also, the control unit 106 of the aerosol-generating device 1b is an example of a control unit which performs control such that after the heating unit has heated a substrate once in accordance with the control sequence received from the other aerosol-generating device, the heating unit cannot heat the substrate in accordance with said control sequence.
Furthermore, the control unit 106 of the aerosol-generating device 1b is an example of a control unit which performs control to store the control sequence received from the other aerosol-generating device by overwriting the control sequence stored in the second memory unit.

Fig. 10 is a flowchart illustrating a first operation example performed when the aerosol-generating device 1a selects a heating profile. Here, a case in which a heating profile is selected as in the example illustrated in fig. 6 will be described by way of example.
As illustrated in the drawing, in the aerosol-generating device 1a, the control unit 106 first determines whether an interrupt notification has been received (step 301).
If it is determined in step 301 that no interrupt notification has been received, the control unit 106 repeats step 301. Meanwhile, if it is determined in step 301 that an interrupt notification has been received, the control unit 106 reads the value of a status register of the sensor unit 102 and determines, on the basis of the value, whether or not the user has performed a double-tap operation on the aerosol-generating device 1a (step 302).
If it is determined in step 302 that the user has not performed a double-tap operation on the aerosol-generating device 1a, the control unit 106 returns the processing to step 301. Meanwhile, if it is determined in step 302 that the user has performed a double-tap operation on the aerosol-generating device 1a, the control unit 106 determines whether or not the slide cover 20 is closed (step 303).
If it is determined in step 303 that the slide cover 20 is not closed, the control unit 106 returns the processing to step 301. Meanwhile, if it is determined in step 303 that the slide cover 20 is closed, the control unit 106 determines whether or not BLE communication is in progress (step 304).
If it is determined in step 304 that BLE communication is in progress, the control unit 106 returns the processing to step 301. Meanwhile, if it is determined in step 304 that BLE communication is not in progress, the control unit 106 specifies the heating profile to be selected (step 305). For example, if the heating profile next in order to the currently selected heating profile is stored, the control unit 106 may specify the heating profile next in order as the heating profile to be selected. Furthermore, if no heating profile placed in order after the currently selected heating profile is stored, the control unit 106 may specify the currently selected heating profile as the heating profile to be selected.
The control unit 106 then selects the heating profile specified in step 305 instead of the currently selected heating profile (step 306). At this time, the notification unit 103 may vibrate the main body device 10 a number of times corresponding to the selected heating profile number or turn on the number of LEDs corresponding to the selected heating profile number.
Fig. 11 is a flowchart illustrating a second operation example performed when the aerosol-generating device 1a selects a heating profile. Here, a case in which a heating profile is selected as in the example illustrated in fig. 7 will be described by way of example.
As illustrated in the drawing, in the aerosol-generating device 1a, the control unit 106 first determines whether an interrupt notification has been received (step 321).
If it is determined in step 321 that no interrupt notification has been received, the control unit 106 repeats step 321. Meanwhile, if it is determined in step 321 that an interrupt notification has been received, the control unit 106 reads the value of the status register of the sensor unit 102 and determines, on the basis of the value, whether or not the user has performed a double-tap operation or a shake operation on the aerosol-generating device 1a (step 322).
If it is determined in step 322 that the user has not performed a double-tap operation or a shake operation on the aerosol-generating device 1a, the control unit 106 returns the processing to step 321. Meanwhile, if it is determined in step 322 that the user has performed a double-tap operation or a shake operation on the aerosol-generating device 1a, the control unit 106 determines whether or not the slide cover 20 is closed (step 323).
If it is determined in step 323 that the slide cover 20 is not closed, the control unit 106 returns the processing to step 321. Meanwhile, if it is determined in step 323 that the slide cover 20 is closed, the control unit 106 determines whether or not BLE communication is in progress (step 324).
If it is determined in step 324 that BLE communication is in progress, the control unit 106 returns the processing to step 321. Meanwhile, if it is determined in step 324 that BLE communication is not in progress, the control unit 106 determines whether or not an interrupt notification has been received again within a period T31 since it was determined in step 321 that an interrupt notification was received (step 325).
If it is determined in step 325 that no interrupt notification has been received within the period T31, the control unit 106 returns the processing to step 321. Meanwhile, if it is determined in step 325 that an interrupt notification has been received within the period T31, the control unit 106 reads the value of the status register of the sensor unit 102 and determines, on the basis of the value, whether or not the user has performed a double-tap operation or a shake operation on the aerosol-generating device 1a (step 326).
If it is determined in step 326 that the user has not performed a double-tap operation or a shake operation on the aerosol-generating device 1a, the control unit 106 returns the processing to step 325. Meanwhile, if it is determined in step 326 that the user has performed a double-tap operation or a shake operation on the aerosol-generating device 1a, the control unit 106 determines whether or not the slide cover 20 is closed (step 327).
If it is determined in step 327 that the slide cover 20 is not closed, the control unit 106 returns the processing to step 321. Meanwhile, if it is determined in step 327 that the slide cover 20 is closed, the control unit 106 determines whether or not BLE communication is in progress (step 328).
If it is determined in step 328 that BLE communication is in progress, the control unit 106 returns the processing to step 321. Meanwhile, if it is determined in step 328 that BLE communication is not in progress, the control unit 106 specifies the heating profile to be selected (step 329). For example, the control unit 106 may specify the heating profile to be selected in accordance with a combination of the operation determined in step 322 and the operation determined in step 326. Furthermore, in the example of fig. 7, if there is no heating profile corresponding to the combination of operations, such as when both the operation determined in step 322 and the operation determined in step 326 are shake operations, the control unit 106 may return the processing to step 325.
The control unit 106 then selects the heating profile specified in step 329 instead of the currently selected heating profile (step 330). At this time, the notification unit 103 may vibrate the main body device 10 a number of times corresponding to the selected heating profile number or turn on the number of LEDs corresponding to the selected heating profile number.
Fig. 12 is a flow chart illustrating an operation example performed when the aerosol-generating device 1a transmits a heating profile. Here, a case in which a heating profile is transmitted as in the example illustrated in fig. 8 will be described by way of example.
As illustrated in the drawing, in the aerosol-generating device 1a, the control unit 106 first establishes a P2P connection with the aerosol-generating device 1b (step 341). In the present embodiment, the P2P connection may be established by any method. At this time, the notification unit 103 vibrates the main body device 10 once for an extended period and turns on the LED lamp 12 in blue, for example.
Next, the control unit 106 determines whether or not the slide cover 20 has been opened (step 342).
If it is determined in step 342 that the slide cover 20 has been opened, the control unit 106 returns the processing to step 341. At this time, the notification unit 103 vibrates the main body device 10 three times and causes the LED lamp 12 to flash in white three times, for example. Meanwhile, if it is determined in step 342 that the slide cover 20 has not been opened, the control unit 106 determines whether or not an interrupt notification has been received within a period T32 since the P2P connection was established (step 343).
If it is determined in step 343 that no interrupt notification was received within the time period T32, the control unit 106 returns the processing to step 341. At this time, the notification unit 103 vibrates the main body device 10 three times and causes the LED lamp 12 to flash in white three times, for example. Meanwhile, if it is determined in step 343 that an interrupt notification has been received within the period T32, the control unit 106 reads the value of the status register of the sensor unit 102 and determines, on the basis of the value, whether or not the user has performed a shake operation on the aerosol-generating device 1a (step 344).
If it is determined in step 344 that the user has not performed a shake operation on the aerosol-generating device 1a, the control unit 106 returns the processing to step 343. Meanwhile, if it is determined in step 344 that the user has performed a shake operation on the aerosol-generating device 1a, the control unit 106 starts transmitting the heating profile selected in fig. 10 or fig. 11 (step 345). At this time, the notification unit 103 vibrates the main body device 10 once for an extended period and causes the LED lamp 12 to flash in blue, for example.
Next, the control unit 106 determines whether or not the slide cover 20 has been opened (step 346).
If it is determined in step 346 that the slide cover 20 has been opened, the control unit 106 returns the processing to step 341. At this time, the notification unit 103 vibrates the main body device 10 three times and causes the LED lamp 12 to flash in white three times, for example. Meanwhile, if it is determined in step 346 that the slide cover 20 has not been opened, the control unit 106 determines whether transmission of the heating profile has been completed within the time period T32 (step 347).
If it is determined in step 347 that transmission of the heating profile has not been completed within the time period T32, the control unit 106 returns the processing to step 341. At this time, the notification unit 103 vibrates the main body device 10 three times and causes the LED lamp 12 to flash in white three times, for example. Meanwhile, if it is determined in step 347 that transmission of the heating profile has been completed within the time period T32, the control unit 106 ends the transmission of the heating profile (step 348). At this time, the notification unit 103 vibrates the main body device 10 once for an extended period and extinguishes the LED lamp 12 that had been turned on in blue, for example.
The control unit 106 then ends the P2P communication (step 349).
Fig. 13 is a flow chart illustrating an operation example performed when the aerosol-generating device 1b receives and stores a heating profile. Here, a case in which a heating profile is received and stored as in the example illustrated in fig. 8 and fig. 9 will be described by way of example.
As illustrated in the drawing, in the aerosol-generating device 1b, the control unit 106 first establishes a P2P connection with the aerosol-generating device 1a (step 361). In the present embodiment, the P2P connection may be established by any method. At this time, the notification unit 103 vibrates the main body device 10 once for an extended period and turns on the LED lamp 12 in blue, for example.
Next, the control unit 106 determines whether or not the slide cover 20 has been opened (step 362).
If it is determined in step 362 that the slide cover 20 has been opened, the control unit 106 returns the processing to step 361. At this time, the notification unit 103 vibrates the main body device 10 three times and causes the LED lamp 12 to flash in white three times, for example. Meanwhile, if it is determined in step 362 that the slide cover 20 has not been opened, the control unit 106 starts receiving the heating profile transmitted by the aerosol-generating device 1a (step 363). At this time, the notification unit 103 vibrates the main body device 10 once for an extended period and causes the LED lamp 12 to flash in blue, for example.
Next, the control unit 106 determines whether or not the slide cover 20 has been opened (step 364).
If it is determined in step 364 that the slide cover 20 has been opened, the control unit 106 returns the processing to step 361. At this time, the notification unit 103 vibrates the main body device 10 three times and causes the LED lamp 12 to flash in white three times, for example. Meanwhile, if it is determined in step 362 that the slide cover 20 has not been opened, the control unit 106 ends the reception of the heating profile (step 365). At this time, the notification unit 103 vibrates the main body device 10 once for an extended period and extinguishes the LED lamp 12 that had been turned on in blue, for example.
Next, the control unit 106 stores the heating profile received in steps 363 to 365 in the second memory unit 1042 (step 366).
The control unit 106 then ends the P2P communication (step 367).
Fig. 14 is a flow chart illustrating an operation example performed when the aerosol-generating device 1b performs heating in accordance with a heating profile.
As illustrated in the drawing, in the aerosol-generating device 1b, the control unit 106 first determines whether or not the slide cover 20 has been opened (step 381).
If it is determined in step 381 that the slide cover 20 has not been opened, the control unit 106 repeats step 381. Meanwhile, if it is determined in step 381 that the slide cover 20 has been opened, the control unit 106 determines whether or not the power button 11 has been depressed (step 382).
If it is determined in step 382 that the power button 11 has not been depressed, the control unit 106 repeats step 382. Meanwhile, if it is determined in step 382 that the power button 11 has been depressed, the control unit 106 starts supplying power from the power source unit 101 to the heating unit 107 (step 383). The control unit 106 then causes the heating unit 107 to heat in accordance with the heating profile stored in the memory unit 104 (step 384).
Next, the control unit 106 determines whether or not the heating profile used for heating in step 384 is the heating profile received from the aerosol-generating device 1a (step 385).
If it is determined in step 384 that the heating profile used for heating in step 384 is the heating profile received from the aerosol-generating device 1a, the control unit 106 sets a setting such that the received heating profile cannot be used again for heating by the heating unit 107 (step 386). The control unit 106 then switches the heating profile to be used for heating by the heating unit 107 to a heating profile other than the received heating profile (step 387). For example, in the example of fig. 9, if, in a state in which heating profile No. 1 has been selected, the control unit 106 receives and uses heating profile No. 5 from the aerosol-generating device 1a, it is preferable to reselect heating profile No. 1 as the heating profile to be used for heating.
Meanwhile, if it is determined in step 385 that the heating profile used for heating in step 384 is not the heating profile received from the aerosol-generating device 1a, the control unit 106 ends the processing without performing steps 386 and 387.

The aerosol-generating device 1 according to the present embodiment is configured to transmit and receive control sequences that define heating to and from other aerosol-generating devices 1 in response to user operations. As a result, in the present embodiment, it is possible for control sequences to be easily transmitted and received to and from other aerosol-generating devices 1.

In the present embodiment, the P2P connection between the aerosol-generating device 1a and the aerosol-generating device 1b is also established in response to a user operation.
It should be noted that the external appearance, the internal configuration, etc., of the aerosol-generating device 1 envisaged by the present embodiment are all the same as in Embodiment 1.
Furthermore, in the present embodiment, the selection of the heating profile, the transmission of the heating profile, the reception and storage of the heating profile, and the heating operation using the heating profile are all the same as in Embodiment 1.
Fig. 15 is a diagram illustrating the establishment of a P2P connection. When the users perform a predetermined operation, the control units 106 of the aerosol-generating device 1a and the aerosol-generating device 1b establish a P2P connection between the aerosol-generating device 1a and the aerosol-generating device 1b. Here, the predetermined operation is exemplified by a shake operation on the aerosol-generating device 1a performed by the user of the aerosol-generating device 1a and a shake operation performed by the user of the aerosol-generating device 1b, but is not limited to this. The predetermined operation may be a double-tap operation, for example, on the aerosol-generating device 1a by the user of the aerosol-generating device 1a, and a double-tap operation, for example, on the aerosol-generating device 1b by the user of the aerosol-generating device 1b.
In this case, the aerosol-generating device 1a is an example of a host device, the aerosol-generating device 1b is an example of another aerosol-generating device, and the motion of the aerosol-generating device 1a and the aerosol-generating device 1b resulting from the predetermined operation performed by the users is an example of a second motion. Furthermore, the control unit 106 of the aerosol-generating device 1a is an example of a control unit which, if a second motion is detected by the detecting unit of the host device and the detecting unit of another aerosol-generating device, performs control to establish a connection with the other aerosol-generating device.
Moreover, in the aerosol-generating device 1a and the aerosol-generating device 1b, the control unit 106 should be configured not to establish a P2P connection when the slide cover 20 is open. This is because if the slide cover 20 is open, it is assumed that heating is being performed in accordance with a heating profile.
In this case, the control unit 106 of the aerosol-generating device 1a is an example of a control unit which, if the opening is opened by the opening and closing portion, performs control such that a connection is not established with the other aerosol-generating device, even if the second motion is detected by the detecting unit of the host device and the detecting unit of the other aerosol-generating device.
Furthermore, in the aerosol-generating device 1a and the aerosol-generating device 1b, the control unit 106 should be configured not to establish a P2P connection when connected to a smartphone. This is because, when connected to a smartphone, a P2P connection has been established with the smartphone.
Furthermore, although the user operation for establishing a P2P connection is defined here to be the same as the user operation for transmitting a heating profile, it may be different from the user operation for transmitting a heating profile. That is, the first motion and the second motion may be the same type of motion or different types of motion.
Fig. 16 is a flowchart illustrating an operation example performed when the aerosol-generating device 1a establishes a P2P connection with the aerosol-generating device 1b. Here, a case in which a P2P connection is established as in the example illustrated in fig. 15 will be described by way of example.
As illustrated in the drawing, in the aerosol-generating device 1a, the control unit 106 first determines whether an interrupt notification has been received (step 401).
If it is determined in step 401 that no interrupt notification has been received, the control unit 106 repeats step 401. Meanwhile, if it is determined in step 401 that an interrupt notification has been received, the control unit 106 reads the value of a status register of the sensor unit 102 and determines, on the basis of the value, whether or not the user has performed a shake operation on the aerosol-generating device 1a (step 402).
If it is determined in step 402 that the user has not performed a shake operation on the aerosol-generating device 1a, the control unit 106 returns the processing to step 401. Meanwhile, if it is determined in step 402 that the user has performed a shake operation on the aerosol-generating device 1a, the control unit 106 determines whether or not the slide cover 20 is closed (step 403).
If it is determined in step 403 that the slide cover 20 is not closed, the control unit 106 returns the processing to step 401. Meanwhile, if it is determined in step 403 that the slide cover 20 is closed, the control unit 106 determines whether or not a connection with a smartphone is in progress (step 404).
If it is determined in step 404 that a connection with a smartphone is in progress, the control unit 106 returns the processing to step 401. Meanwhile, if it is determined in step 404 that a connection with a smartphone is not in progress, the control unit 106 starts a transition to a P2P mode (step 405). That is, the control unit 106 starts searching for a nearby aerosol-generating device 1 on which a shake operation is being performed, as the counterpart for the P2P connection. At this time, the notification unit 103 vibrates the main body device 10 once for an extended period and causes the LED lamp 12 to flash in blue, for example.
Next, the control unit 106 determines whether or not the transition to the P2P mode has been canceled (step 406).
If it is determined in step 406 that the transition to the P2P mode has been canceled, the control unit 106 returns the processing to step 401. At this time, the notification unit 103 vibrates the main body device 10 three times and causes the LED lamp 12 to flash in white three times, for example. Meanwhile, if it is determined in step 406 that the transition to the P2P mode has not been canceled, the control unit 106 determines whether or not a timeout has occurred (step 407).
If it is determined in step 407 that a timeout has occurred, the control unit 106 returns the processing to step 401. At this time, the notification unit 103 vibrates the main body device 10 three times and causes the LED lamp 12 to flash in white three times, for example. Meanwhile, if it is determined in step 407 that a timeout has not occurred, the control unit 106 determines whether or not the counterpart for the P2P connection is a smartphone application (step 408).
If it is determined in step 408 that the counterpart for the P2P connection is not a smartphone application, the control unit 106 completes the P2P connection with the aerosol-generating device 1b (step 409).
Meanwhile, if it is determined in step 408 that the counterpart for the P2P connection is a smartphone application, the control unit 106 completes the P2P connection with said application (step 410).

The aerosol-generating device 1 according to the present embodiment is configured to establish a connection with another aerosol-generating device 1 in response to a user operation. As a result, in the present embodiment, it is possible for a connection with another aerosol-generating device 1 to be established easily.
