[0001] The present disclosure relates to a communication system, a terminal device, and a control method for sucking an aerosol, a gas, or the like.

[0002] In recent years, technologies related to suction devices that generate substances to be sucked by users have been widely developed. For example, a suction device generates an aerosol using a base material including an aerosol source, a fragrance source, or the like. Then, the user can suck the aerosol and taste the flavor.

[0003] Here, in order to further improve the fragrance tasted by the user, it is conceivable to evaluate the aerosol generated by the suction device. For example, Patent Document 1 (Japanese Patent No. 6839181) discloses evaluating the taste by the aerosol generated by each of a plurality of base materials.

[0004] Japanese Patent No. 6839181

[0005] There are a plurality of factors that can change the taste tasted by the user. However, the technique described in Patent Document 1 may be limited to the evaluation of the taste due to the composition of the base material.

[0006] In view of the above problems, the present invention provides a technique that can further improve the quality of the user experience with respect to the suction device.

[0007] To solve the above problems, a communication system according to an embodiment of the present disclosure includes a suction device that heats a base material based on a heating profile to generate an aerosol, and a terminal device that can be communicatively connected to the suction device. The terminal device displays predetermined graphic information indicating the characteristics of the generated aerosol for each of a plurality of the heating profiles, receives a user's selection for at least one of the plurality of the predetermined graphic information corresponding to each of the plurality of the heating profiles, transmits the heating profile corresponding to the selected at least one of the predetermined graphic information to the suction device, and the suction device controls the heating of the base material based on the heating profile received from the terminal device.

[0008] Furthermore, in order to solve the above problems, the terminal device of the embodiment of the present disclosure includes an output unit that displays a plurality of predetermined graphic information indicating the characteristics of aerosols generated from a substrate containing an aerosol source, and an input unit that accepts a user's selection of at least one of the plurality of predetermined graphic information corresponding to each of the plurality of substrates, wherein the output unit includes a display unit that displays information about the substrate corresponding to the selected at least one predetermined graphic information.

[0009] Furthermore, in order to solve the above problems, the control method of the embodiment of the present disclosure is a control method for a terminal device, comprising: a first display step of displaying a plurality of predetermined graphic information indicating the characteristics of aerozoes generated from a substrate containing an aerosol source for each substrate; an input step of receiving a user's selection for at least one of the plurality of predetermined graphic information corresponding to each of the plurality of substrates; and a second display step of displaying information about the substrate corresponding to the selected at least one of the predetermined graphic information.

[0012] In one embodiment of this disclosure, a terminal device displays a plurality of predetermined graphic information and accepts a user selection for at least one of them. The predetermined graphic information visualizes the characteristics of aerosols generated from a substrate. Therefore, by visually viewing the displayed predetermined graphic information, the user can grasp the characteristics of aerosols generated from the substrate. Based on the grasped characteristics, the user can select at least one predetermined graphic information. That is, the user can select information about at least one substrate based on the characteristics of aerosols generated from each of the plurality of substrates. Information about the substrate includes, for example, information about the substrate itself, such as the type of substrate, and information about heating the substrate. The substrate is, for example, an article containing an aerosol source and / or flavoring components. Information about heating the substrate includes, for example, the heating temperature of the substrate and a heating profile, which is control information for heating the substrate. Therefore, in one embodiment of this disclosure, the user can select the type of substrate, the heating temperature of the substrate, and the heating profile based on the characteristics of aerosols generated from each of the plurality of substrates, thereby improving the quality of the user experience.

[0013] The terminal device may transmit information regarding the heating of the substrate, such as the heating temperature and heating profile of the substrate, to the suction device based on predetermined graphic information selected by the user. In this case, the suction device may heat the substrate based on the received heating information. The received heating information may be identified or created based on predetermined graphic information selected by the user.

[0014] Furthermore, the terminal device may display information about the substrate itself, such as the type of substrate, based on predetermined graphic information selected by the user. Subsequently, the terminal device may display recommended substrates or types of substrates to the user based on predetermined graphic information selected by the user.

[0015] Furthermore, in addition to transmitting information regarding the heating of the substrate, such as the heating temperature and heating profile of the substrate, to the suction device based on predetermined graphic information selected by the user, the terminal device may also display the substrate itself or the type of substrate recommended to the user based on predetermined graphic information selected by the user.

[0016] <<1. Example of System Configuration>> Below, an example of the configuration of a communication system 10, which is one embodiment of the present disclosure, will be described. Figure 1 is a schematic diagram showing an example of the configuration of a communication system 10 according to this embodiment. The communication system 10 illustrated in Figure 1 is an example of the configuration of a communication system 10 in which a user selects a heating profile based on the characteristics of aerosols generated from each of a plurality of substrates, and a suction device receives the selected heating profile.

[0017] As shown in Figure 1, the communication system 10 includes a suction device 100, a terminal device 200, and a server device 500. The suction device 100 is a device that generates a substance to be aspirated by the user 400. The substance to be aspirated by the user 400 is, for example, an aerosol. The terminal device 200 is a device capable of creating and displaying various types of information. The server device 500 is a device that stores various types of information and can transmit at least one piece of information to the terminal device 200 in response to a request from the terminal device 200. The suction device 100, the terminal device 200, and the server device 500 can communicate with each other via a predetermined network 300.

[0018] The terminal device 200 displays a plurality of predetermined graphic information and accepts the user 400's selection of at least one of them. Each of the plurality of predetermined graphic information visualizes the characteristics of the aerosol generated from the substrate.

[0019] The predetermined graphic information is created from sensing information, such as aerosol information and substrate information, which are sensed by the sensor unit of the suction device 100. The predetermined graphic information may be, for example, various points, lines, and figures associated with the aerosol information and substrate information. Furthermore, the predetermined graphic information may change color based on color information associated with the aerosol information and substrate information. Moreover, the predetermined graphic information is not limited to points, lines, and figures, but may be anything, including any image.

[0020] Furthermore, each of the multiple predetermined graphic information pieces created and displayed by the terminal device 200 may change over time. The predetermined graphic information may change over time in terms of, for example, the size of points, the length of lines, the size and shape of figures, or the content of arbitrary images. Also, the predetermined graphic information may change in color over time. Moreover, the predetermined graphic information may be any video.

[0021] Each of the multiple predetermined graphic information pieces created and displayed by the terminal device 200 may provide the user 400 with characteristics of the aerosol generated from the substrate. The characteristics of the aerosol generated from the substrate may be any characteristics or features related to the aerosol generated from the substrate, such as the temperature, smoke volume, taste, and aerosol properties derived from the type of substrate (e.g., regular or menthol). The user 400 may be able to grasp the characteristics of the aerosol generated from the substrate by visually viewing the predetermined graphic information.

[0022] Each of the multiple predetermined graphic pieces of information created and displayed by the terminal device 200 may be changeable over time. For example, the terminal device 200 may change the displayed predetermined graphic pieces of information to provide a predetermined number of aerosol characteristics within a predetermined time. By visually observing the predetermined graphic pieces of information that change over time, the user 400 can grasp the characteristics of multiple aerosols within a predetermined time. Therefore, when the user 400 takes multiple puffs during a single smoking session, it may be possible to grasp the characteristics of the aerosols from each of those multiple puffs.

[0023] Therefore, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate and the characteristics of each aerosol from multiple puffs when multiple puffs are taken during a single smoking session by visually viewing a plurality of predetermined graphic information displayed on the terminal device 200. Based on the understood aerosol characteristics, the user 400 can select at least one predetermined graphic information.

[0024] The terminal device 200 requests at least one heating profile corresponding to predetermined graphic information selected by the user 400 from the server device 500 via a predetermined network 300. The terminal device 200 also transmits the heating profile received from the server device 500 to the suction device 100 via the predetermined network 300.

[0025] The server device 500 can store multiple heating profiles. A heating profile is control information for controlling the temperature at which the aerosol source is heated. Heating profiles will be described later. Upon request from the terminal device 200, the server device 500 transmits at least one heating profile to the terminal device 200 via a predetermined network 300. Note that the server device 500 does not necessarily have to be included in the communication system 10; the terminal device 200 may store the heating profiles instead of the server device 500.

[0026] The suction device 100 receives a heating profile from the terminal device 200 and controls the heating of the heating section.

[0027] Thus, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate and the characteristics of each aerosol from multiple puffs when multiple puffs are taken during a single smoking session by viewing multiple predetermined graphic information displayed on the terminal device 200. Based on the understood aerosol characteristics, the user 400 can select at least one predetermined graphic information and receive a heating profile corresponding to the selected predetermined graphic information. Therefore, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate and select the heating profile to receive, thereby improving the quality of the user experience.

[0028] Note that the communication system 10 is not limited to the configuration example shown in Figure 1. If the terminal device 200 displays information about the substrate itself, such as the type of substrate, based on predetermined graphic information selected by the user, the communication system 10 only needs to include at least the terminal device 200.

[0029] <<2. Example of Suction Device Configuration>> A suction device is a device that generates a substance to be aspirated by the user. In the following explanation, the substance generated by the suction device will be described as an aerosol. Alternatively, the substance generated by the suction device may be a gas. In the following explanation, the act of the user aspirating the substance generated by the suction device will be simply referred to as "suction" or "puffing".

[0030] In the configuration examples described below, when multiple elements having corresponding functional configurations are assigned a reference code containing the same number to clearly indicate the correspondence, and each element may be distinguished by adding an alphabet corresponding to the configuration example after the number. For example, each of the suction devices in the multiple configuration examples is referred to as the suction device 100A in the first configuration example, the suction device 100B in the second configuration example, and the suction device 100C in the third configuration example, thereby clearly indicating the correspondence and distinguishing each from the others. On the other hand, when there is no particular need to distinguish each of the multiple elements having corresponding functional configurations in the multiple configuration examples, only a reference code containing the same number may be assigned. For example, when there is no particular need to distinguish between the suction device 100A in the first configuration example, the suction device 100B in the second configuration example, and the suction device 100C in the third configuration example, they may simply be referred to as the suction device 100.

[0031] Furthermore, for multiple elements having corresponding functional configurations across multiple configuration examples, the explanation may be omitted in subsequent configuration examples after being described in detail in the previously mentioned configuration example, with reference to that explanation. In such cases, the omitted explanation can be appropriately replaced by changing the alphabet of the reference code attached to each element in the explanation given in the previously mentioned configuration example to the alphabet corresponding to the subsequent configuration example. For example, if the suction device 100A related to the first configuration example is described in detail, and the explanation of the suction device 100B related to the second configuration example is omitted, the omitted explanation can be replaced by changing 100A to 100B in the explanation given in the first configuration example.

[0032] The following describes various configurations of the suction device with reference to Figures 2 to 13.

[0033] <2.1. Integrated Substrate Suction Device> An integrated substrate suction device is a suction device in which a substrate containing an aerosol source is integrated with the suction device. The first to fourth configuration examples described below are examples of configurations for an integrated substrate suction device.

[0034] (1) First Configuration Example The suction device according to this configuration example generates an aerosol by heating an aerosol source as a liquid. The suction device according to this configuration example consists of two parts: a power supply unit and a cartridge. This configuration example will be described below with reference to Figure 2.

[0035] Figure 2 is a schematic diagram illustrating a first configuration example of a suction device. As shown in Figure 2, the suction device 100A according to this configuration example includes a power supply unit 110A and a cartridge 120A. The power supply unit 110A and the cartridge 120A are configured to be detachable from each other. Suction by the user is performed with the cartridge 120A attached to the power supply unit 110A.

[0036] As shown in Figure 2, the power supply unit 110A includes a power supply unit 111A, a sensor unit 112A, a notification unit 113A, a storage unit 114A, a communication unit 115A, and a control unit 116A. The cartridge 120A includes a heating unit 121A, a liquid induction unit 122A, a liquid storage unit 123A, and a mouthpiece 124A. An air passage 180A is formed in the cartridge 120A. Each component will be described in order below.

[0037] The power supply unit 111A stores power. The power supply unit 111A then supplies power to each component of the suction device 100A. The power supply unit 111A may be composed of a rechargeable battery, such as a lithium-ion secondary battery. The power supply unit 111A may be charged by connecting to an external power source via a USB (Universal Serial Bus) cable or the like. Alternatively, the power supply unit 111A may be charged wirelessly using power transmission technology while not connected to a power-transmitting device. Furthermore, the power supply unit 111A may be removed from the suction device 100A, or it may be replaced with a new power supply unit 111A.

[0038] The sensor unit 112A detects various information related to the suction device 100A. The sensor unit 112A then outputs the detected information to the control unit 116A. For example, the sensor unit 112A is composed of a pressure sensor such as a microphone condenser, a flow sensor, or a temperature sensor. When the sensor unit 112A detects a value associated with suction by the user, it outputs information to the control unit 116A indicating that suction has been performed by the user. As another example, the sensor unit 112A is composed of an input device that receives information from the user, such as a button or switch. In particular, the sensor unit 112A may include a button that instructs the start / stop of aerosol generation. The sensor unit 112A then outputs the information input by the user to the control unit 116A.

[0039] The notification unit 113A notifies the user of information. For example, the notification unit 113A is composed of a light-emitting device such as an LED (Light Emitting Diode). In this case, the notification unit 113A emits light in different patterns depending on whether the power supply unit 111A needs charging, whether the power supply unit 111A is charging, or whether an abnormality occurs in the suction device 100A. The light-emitting pattern here is a concept that includes color and the timing of turning on / off. The notification unit 113A may be composed of, together with or instead of, a display device that displays an image, a sound output device that outputs sound, and a vibration device that vibrates.

[0040] The memory unit 114A stores various information for the operation of the suction device 100A. The memory unit 114A is composed of a non-volatile storage medium such as flash memory. An example of the information stored in the memory unit 114A is information related to the OS (Operating System) of the suction device 100A, such as the control contents of each component by the control unit 116A. Another example of the information stored in the memory unit 114A is information related to suction by the user, such as the number of suctions, suction time, and cumulative suction time.

[0041] The communication unit 115A is a communication interface for sending and receiving information between the suction device 100A and other devices. The communication unit 115A communicates in accordance with any wired or wireless communication standard. Examples of such communication standards include wireless LAN (Local Area Network), wired LAN, Wi-Fi®, or Bluetooth®. As an example, the communication unit 115A transmits information about suction performed by the user to a smartphone in order to display the information on the smartphone. As another example, the communication unit 115A receives new OS information from a server in order to update the OS information stored in the storage unit 114A.

[0042] The control unit 116A functions as an arithmetic processing unit and control unit, and controls the overall operation of the suction device 100A according to various programs. The control unit 116A is implemented by electronic circuits such as a CPU (Central Processing Unit) and a microprocessor. In addition, the control unit 116A may include a ROM (Read Only Memory) for storing the programs and calculation parameters to be used, and a RAM (Random Access Memory) for temporarily storing parameters that change as needed. The suction device 100A performs various processes based on the control of the control unit 116A. Examples of processes controlled by the control unit 116A include supplying power from the power supply unit 111A to other components, charging the power supply unit 111A, detecting information by the sensor unit 112A, notifying information by the notification unit 113A, storing and reading information by the storage unit 114A, and transmitting and receiving information by the communication unit 115A. Other processes performed by the suction device 100A, such as inputting information to each component and processing based on information output from each component, are also controlled by the control unit 116A.

[0043] The liquid storage unit 123A stores an aerosol source. The aerosol source is atomized by heating to generate an aerosol. The aerosol source is, for example, a polyhydric alcohol such as glycerin and propylene glycol, and a liquid such as water. The aerosol source may further contain a tobacco raw material or an extract derived from a tobacco raw material that releases a flavor component when heated. The aerosol source may further contain nicotine. When the suction device 100A is a medical inhaler such as a nebulizer, the aerosol source may contain a drug for the patient to inhale.

[0044] The liquid guiding unit 122A guides and holds the aerosol source, which is a liquid stored in the liquid storage unit 123A, from the liquid storage unit 123A. The liquid guiding unit 122A is, for example, a wick formed by twisting a fibrous material such as glass fiber or a porous material such as porous ceramic. The liquid guiding unit 122A is in liquid communication with the liquid storage unit 123A. Therefore, the aerosol source stored in the liquid storage unit 123A spreads throughout the liquid guiding unit 122A by capillary action.

[0045] The heating unit 121A generates an aerosol by heating the aerosol source, thereby atomizing it. The heating unit 121A is made of any material such as metal or polyimide and can take any shape, such as a coil, film, or blade. The heating unit 121A is positioned close to the liquid guide unit 122A. In the example shown in Figure 2, the heating unit 121A is made of a metal coil and is wrapped around the liquid guide unit 122A. Therefore, when the heating unit 121A generates heat, the aerosol source held in the liquid guide unit 122A is heated and atomized, generating an aerosol. The heating unit 121A generates heat when power is supplied from the power supply unit 111A. For example, power may be supplied and an aerosol may be generated during the period when the sensor unit 112A detects that the user has performed an inhalation. As another example, power may be supplied and an aerosol may be generated when the sensor unit 112A detects that a predetermined user input (for example, pressing a button to instruct the start / stop of aerosol generation) has been performed. Subsequently, if the sensor unit 112A detects that a predetermined user input has been made (for example, pressing the button that instructs the start / stop of aerosol generation again), the power supply may be stopped.

[0046] The air passage 180A is the passage for air drawn in by the user. The air passage 180A has a tubular structure with an air inlet 181A, which is the entrance for air into the air passage 180A, and an air outlet 182A, which is the exit for air from the air passage 180A, at both ends. When the user draws air in, air flows into the air passage 180A from the air inlet 181A and air flows out of the air passage 180A from the air outlet 182A. For example, the air inlet 181A may be the gap between the power supply unit 110A and the cartridge 120A when the cartridge 120A is attached to the power supply unit 110A. The air outlet 182A is located in the mouthpiece 124A.

[0047] In the middle of the air flow path 180A, a liquid guiding part 122A is arranged. The aerosol generated by the heating part 121A is mixed with the air flowing in from the air inlet hole 181A. Then, with the suction by the user, the mixed fluid of the aerosol and the air is transported to the air outlet hole 182A as shown by the arrow 190A.

[0048] The mouthpiece 124A is a member that is held by the user during suction. The air outlet hole 182A of the air flow path 180A is arranged in the mouthpiece 124A. By holding and sucking the mouthpiece 124A, the user can take into the oral cavity the mixed fluid of the aerosol and the air transported by the air flow path 180A.

[0049] (2) Second configuration example The suction device according to this configuration example generates an aerosol by heating an aerosol source as a liquid. The suction device according to this configuration example consists of three components: a power supply unit, a cartridge, and a flavor - imparting cartridge. Hereinafter, this configuration example will be described while referring to FIG. 3.

[0050] FIG. 3 is a schematic diagram schematically showing a second configuration example of the suction device. As shown in FIG. 3, the suction device 100B according to this configuration example includes a power supply unit 110B, a cartridge 120B, and a flavor - imparting cartridge 130. The power supply unit 110B and the cartridge 120B are configured to be detachable from each other. Also, the cartridge 120B and the flavor - imparting cartridge 130 are configured to be detachable from each other. The suction by the user is performed in a state where the cartridge 120B, the flavor - imparting cartridge 130, and the power supply unit 110B are attached to each other.

[0051] As shown in FIG. 3, the power supply unit 110B includes a power supply part 111B, a sensor part 112B, a notification part 113B, a storage part 114B, a communication part 115B, and a control part 116B. The cartridge 120B includes a heating part 121B, a liquid guiding part 122B, and a liquid storage part 123B. The flavor - imparting cartridge 130 includes a flavor source 131 and a mouthpiece 124B. An air flow path 180B is formed in the cartridge 120B and the flavor - imparting cartridge 130. Hereinafter, each component will be described in order.

[0052] Each component of the power supply unit 110B is substantially the same as the corresponding component included in the suction device 100A according to the first configuration example. The heating unit 121B, liquid induction unit 122B, liquid storage unit 123B, and mouthpiece 124B are also substantially the same as the corresponding component included in the suction device 100A according to the first configuration example.

[0053] Flavoring agent 131 is a component for imparting flavor components to the aerosol. Flavoring agent 131 may be tobacco-derived, such as processed products made by molding shredded tobacco or tobacco raw materials into granules, sheets, or powders. Flavoring agent 131 may also include non-tobacco-derived components made from plants other than tobacco (e.g., mint and herbs). For example, flavoring agent 131 may contain nicotine. As another example, flavoring agent 131 may contain flavoring components such as menthol. Flavoring agent 131 may be placed inside a container such as a capsule.

[0054] The air passage 180B has the same configuration as the air passage 180A according to the first configuration example. However, in addition to the liquid guide section 122B, a flavor source 131 is placed downstream of the liquid guide section 122B (closer to the air outlet hole 182B) in the middle of the air passage 180B. The aerosol generated by the heating section 121B is mixed with the air flowing in from the air inlet hole 181B. Then, as the user inhales, the mixed fluid of aerosol and air is transported to the air outlet hole 182B by passing through the flavor source 131, as shown by arrow 190B. When the mixed fluid of aerosol and air passes through the flavor source 131, the flavor components contained in the flavor source 131 are imparted to the aerosol.

[0055] (3) Third Configuration Example The suction device according to this configuration example generates an aerosol using an acid source and a base source. This configuration example will be described below with reference to Figure 4.

[0056] Figure 4 is a schematic diagram illustrating a third configuration example of the suction device. As shown in Figure 4, the suction device 100C according to this configuration example includes a power supply unit 110C and a cartridge 120C. The power supply unit 110C and the cartridge 120C are configured to be detachable from each other. Suction by the user is performed with the cartridge 120C attached to the power supply unit 110C.

[0057] As shown in Figure 4, the power supply unit 110C includes a power supply unit 111C, a sensor unit 112C, a notification unit 113C, a storage unit 114C, a communication unit 115C, and a control unit 116C. The cartridge 120C includes a heating unit 121C, an acid source 125, a base source 126, and a mouthpiece 124C. An air passage 180C is also formed in the cartridge 120C. Each component will be described in order below.

[0058] Each component of the power supply unit 110C and the mouthpiece 124C are substantially identical to the corresponding components included in the suction device 100A according to the first configuration example.

[0059] Acid source 125 is an aerosol source containing acid. When acid source 125 is heated, it is atomized, and acid vapor, which is a vapor containing acid, is produced. The acid contained in acid source 125 may be an organic acid or an inorganic acid. For example, acid source 125 may contain a carboxylic acid, an α-keto acid, a 2-oxo acid, or lactic acid. Acid source 125 may be a solid or a liquid.

[0060] The base source 126 is an aerosol source containing a base. When heated, the base source 126 is atomized, producing base vapor, which is a vapor containing a base. The base source 126 may be a solid or a liquid. The base source 126 may further contain nicotine.

[0061] The heating unit 121C generates an aerosol by heating the aerosol source and atomizing it. For example, the heating unit 121C can be made of any material such as metal or polyimide and can be any shape such as a coil, film, or blade. The heating unit 121C is positioned close to the acid source 125 and the base source 126. In the example shown in Figure 4, the heating unit 121C is formed in a blade shape and positioned between the acid source 125 and the base source 126. Therefore, when the heating unit 121C generates heat, the acid source 125 and the base source 126 are heated and atomized. Of course, separate heating units may be provided for heating the acid source 125 and the base source 126. The heating unit 121C generates heat when power is supplied from the power supply unit 111C. As an example, power may be supplied during the period when the sensor unit 112C detects that the user has performed inhalation, and acid vapor and base vapor may be generated. As another example, when the sensor unit 112C detects that a predetermined user input has been made, power may be supplied and acid vapor and base vapor may be generated. Subsequently, when the sensor unit 112C detects that a predetermined user input has been made again, power supply may be stopped.

[0062] The air passage 180C has the same configuration as the air passage 180A according to the first configuration example. However, an acid source 125 and a base source 126 are placed in the middle of the air passage 180C. When the acid vapor and base vapor generated by the heating unit 121C are mixed in the air passage 180C, a chemical reaction generates an aerosol containing salt particles. The generated aerosol containing salt particles is then mixed with air flowing in from the air inlet 181C. Subsequently, upon suction by the user, the mixed fluid of the aerosol containing salt particles and air is transported to the air outlet 182C as shown by arrow 190C.

[0063] (4) Fourth Configuration Example The suction device according to this configuration example generates an aerosol by applying vibration to an aerosol source which is a liquid. This configuration example will be explained below with reference to Figure 5.

[0064] Figure 5 is a schematic diagram illustrating a fourth configuration example of the suction device. As shown in Figure 5, the suction device 100D according to this configuration example includes a power supply unit 110D and a cartridge 120D. The power supply unit 110D and the cartridge 120D are configured to be detachable from each other. Suction by the user is performed with the cartridge 120D attached to the power supply unit 110D.

[0065] As shown in Figure 5, the power supply unit 110D includes a power supply unit 111D, a sensor unit 112D, a notification unit 113D, a storage unit 114D, a communication unit 115D, and a control unit 116D. The cartridge 120D includes a heating unit 121D, a liquid induction unit 122D, a liquid storage unit 123D, a vibration unit 127, and a mouthpiece 124D. An air passage 180D is also formed in the cartridge 120D. Each component will be described in order below.

[0066] Each component of the power supply unit 110D is substantially the same as the corresponding component included in the suction device 100A according to the first configuration example. The liquid storage unit 123D and the mouthpiece 124D are also substantially the same as the corresponding component included in the suction device 100A according to the first configuration example.

[0067] The liquid guide unit 122D guides and holds the aerosol source, which is a liquid stored in the liquid storage unit 123D, from the liquid storage unit 123D to the vibrating unit 127. An example of the liquid guide unit 122D is a wick formed by twisting a fibrous material such as glass fiber or a porous material such as porous ceramic. Another example of the liquid guide unit 122D is a plate capable of absorbing the aerosol source, which is a liquid, and guiding it to the vibrating unit 127. The liquid guide unit 122D is in liquid communication with the liquid storage unit 123D. Therefore, as shown by arrow 191, the aerosol source stored in the liquid storage unit 123D is guided to the surface of the vibrating unit 127 by the liquid guide unit 122D.

[0068] The vibrating unit 127 generates an aerosol by applying vibration to the aerosol source, thereby atomizing the aerosol source. For example, the vibrating unit 127 is composed of a plate-shaped member containing piezoelectric ceramics that function as an ultrasonic transducer, or a member that generates surface acoustic waves (SAW). When the vibrating unit 127 vibrates, the aerosol source guided to the surface of the vibrating unit 127 by the liquid induction unit 122D is atomized by the ultrasonic waves generated by the vibration of the vibrating unit 127, thereby generating an aerosol. The vibrating unit 127 vibrates when power is supplied from the power supply unit 111D. As an example, power may be supplied and an aerosol may be generated during the period when the sensor unit 112D detects that the user has performed an inhalation. As another example, power may be supplied and an aerosol may be generated when the sensor unit 112D detects that a predetermined user input has been made. Subsequently, when the sensor unit 112D detects that a predetermined user input has been made, the power supply may be stopped.

[0069] The air passage 180D has the same configuration as the air passage 180A in the first configuration example. However, a liquid guide section 122D is positioned in the middle of the air passage 180D. The aerosol generated by the vibrating section 127 is mixed with the air flowing in from the air inlet hole 181D. Then, as the user inhales, the mixed fluid of aerosol and air is transported to the air outlet hole 182D, as shown by arrow 190D.

[0070] In addition, the suction device 100D according to this configuration example may have a flavoring cartridge 130 positioned downstream of the cartridge 120D, similar to the suction device 100B according to the second configuration example. In other words, the suction device 100D according to this configuration example may consist of three components: a power supply unit 110D, a cartridge 120D, and a flavoring cartridge 130.

[0071] <2.2. External Substrate Type Suction Device> An external substrate type suction device is a suction device to which a substrate containing an aerosol source is attached externally. The fifth to eighth configuration examples described below are examples of configurations for an external substrate type suction device.

[0072] (1) Fifth Configuration Example The suction device according to this configuration example generates an aerosol by heating a substrate containing an aerosol source from inside the substrate. This configuration example will be described below with reference to Figure 6.

[0073] Figure 6 is a schematic diagram illustrating a fifth configuration example of the suction device. As shown in Figure 6, the suction device 100E according to this configuration example includes a power supply unit 111E, a sensor unit 112E, a notification unit 113E, a storage unit 114E, a communication unit 115E, a control unit 116E, a heating unit 121E, and a holding unit 140E. With the stick-shaped substrate 150E held in the holding unit 140E, suction is performed by the user. Each component will be described in order below.

[0074] Each of the power supply unit 111E, sensor unit 112E, storage unit 114E, communication unit 115E, and control unit 116E is substantially the same as the corresponding component included in the suction device 100A according to the first configuration example.

[0075] The holding portion 140E has an internal space 141E and holds the stick-type substrate 150E while accommodating a portion of it in the internal space 141E. The holding portion 140E has an opening 142E that communicates the internal space 141E to the outside and holds the stick-type substrate 150E inserted into the internal space 141E from the opening 142E. For example, the holding portion 140E is a cylindrical body with the opening 142E and bottom portion 143E as its base, defining a columnar internal space 141E. The holding portion 140E is configured such that, in at least a portion in the height direction of the cylindrical body, its inner diameter is smaller than the outer diameter of the stick-type substrate 150E, and can hold the stick-type substrate 150E inserted into the internal space 141E by compressing it from the outer circumference. The holding portion 140E also has the function of defining an airflow path through the stick-type substrate 150E. The air inlet, which is the entry point for air into the flow path, is located, for example, at the bottom 143E. On the other hand, the air outlet, which is the exit point for air from the flow path, is the opening 142E.

[0076] The stick-type base material 150E is a stick-shaped component. The stick-type base material 150E includes a base material portion 151E and a suction mouth portion 152E. The base material portion 151E includes an aerosol source. The aerosol source is as described above in the first configuration example. In this configuration example, the aerosol source is not limited to a liquid, but may be a solid. At least a part of the base material portion 151E is housed in the internal space 141E of the holding portion 140E when the stick-type base material 150E is held by the holding portion 140E. The suction mouth portion 152E is a component that is held in the user's mouth when suctioning. At least a part of the suction mouth portion 152E protrudes from the opening 142E when the stick-type base material 150E is held by the holding portion 140E. Then, when the user puts the mouthpiece 152E protruding from the opening 142E into their mouth and sucks, air flows into the inside of the holding part 140E from an air inlet hole (not shown). The incoming air passes through the internal space 141E of the holding part 140E, that is, through the base material part 151E, and reaches the user's mouth together with the aerosol generated from the base material part 151E.

[0077] The heating unit 121E generates an aerosol by heating the aerosol source, thereby atomizing the aerosol source. The heating unit 121E is made of any material such as metal or polyimide. For example, the heating unit 121E is configured in a blade shape and is positioned to protrude from the bottom 143E of the holding unit 140E into the internal space 141E of the holding unit 140E. Therefore, when the stick-type substrate 150E is inserted into the holding unit 140E, the blade-shaped heating unit 121E is inserted into the inside of the stick-type substrate 150E, piercing the substrate portion 151E of the stick-type substrate 150E. When the heating unit 121E generates heat, the aerosol source contained in the stick-type substrate 150E is heated from the inside of the stick-type substrate 150E and atomized, generating an aerosol. The heating unit 121E generates heat when power is supplied from the power supply unit 111E. As an example, power may be supplied and an aerosol may be generated when the sensor unit 112E detects that a predetermined user input has been made. When the temperature of the stick-type substrate 150E heated by the heating unit 121E reaches a predetermined temperature, the user can inhale. Subsequently, power may be stopped when the sensor unit 112E detects that a predetermined user input has been made. As another example, power may be supplied and an aerosol may be generated during the period in which the sensor unit 112E detects that the user has inhaled.

[0078] The notification unit 113E has the same function as the notification unit 113A in the first configuration example. Furthermore, the notification unit 113E notifies the user that suction is now possible. This information is notified when the temperature of the stick-type substrate 150E, heated by the heating unit 121E, reaches a predetermined temperature.

[0079] (2) Sixth Configuration Example The suction device according to this configuration example generates an aerosol by heating a substrate containing an aerosol source from outside the substrate. This configuration example will be described below with reference to Figure 7.

[0080] Figure 7 is a schematic diagram illustrating a sixth configuration example of the suction device. As shown in Figure 7, the suction device 100F according to this configuration example includes a power supply unit 111F, a sensor unit 112F, a notification unit 113F, a storage unit 114F, a communication unit 115F, a control unit 116F, a heating unit 121F, a holding unit 140F, and a heat insulating unit 144F. With the stick-shaped substrate 150F held in the holding unit 140F, suction is performed by the user. Each component will be described in order below.

[0081] Each of the power supply unit 111F, sensor unit 112F, notification unit 113F, storage unit 114F, communication unit 115F, control unit 116F, and holding unit 140F is substantially the same as the corresponding component included in the suction device 100E according to the fifth configuration example. Furthermore, the stick-type substrate 150F is substantially the same as the stick-type substrate 150E according to the fifth configuration example.

[0082] The heating unit 121F generates an aerosol by heating the aerosol source and atomizing it. The heating unit 121F is made of any material such as metal or polyimide. For example, the heating unit 121F is made of a film and is arranged to cover the outer circumference of the holding unit 140F. When the heating unit 121F generates heat, the aerosol source contained in the stick-shaped substrate 150F is heated from the outer circumference of the stick-shaped substrate 150F and atomized, generating an aerosol. The heating unit 121F generates heat when power is supplied from the power supply unit 111F. For example, power may be supplied when a predetermined user input is detected by the sensor unit 112F. When the temperature of the stick-shaped substrate 150F heated by the heating unit 121F reaches a predetermined temperature, the user can inhale. After that, the power supply may be stopped when a predetermined user input is detected by the sensor unit 112F. As another example, power may be supplied and an aerosol may be generated during the period when the sensor unit 112F detects that the user has inhaled.

[0083] The heat insulating section 144F prevents heat transfer from the heating section 121F to other components of the suction device 100F. The heat insulating section 144F is positioned to cover at least the outer periphery of the heating section 121F. For example, the heat insulating section 144F is made of vacuum insulating material, aerogel insulating material, etc. Vacuum insulating material is an insulating material in which heat conduction by gas is reduced to almost zero by wrapping glass wool and silica (silicon powder) etc. in a resin film and creating a high vacuum.

[0084] (3) Seventh Configuration Example The suction device according to this configuration example generates an aerosol by heating a substrate containing an aerosol source from inside the substrate and from outside the substrate. This configuration example will be described below with reference to Figure 8.

[0085] Figure 8 is a schematic diagram illustrating a seventh configuration example of the suction device. As shown in Figure 8, the suction device 100G according to this configuration example includes a power supply unit 111G, a sensor unit 112G, a notification unit 113G, a storage unit 114G, a communication unit 115G, a control unit 116G, a heating unit 121G-1, a heating unit 121G-2, a holding unit 140G, and a heat insulating unit 144G. With the stick-shaped substrate 150G held in the holding unit 140G, suction is performed by the user. Each component will be described in order below.

[0086] Each of the power supply unit 111G, sensor unit 112G, notification unit 113G, storage unit 114G, communication unit 115G, control unit 116G, holding unit 140G, and heat insulation unit 144G is substantially the same as the corresponding component included in the suction device 100F according to the sixth configuration example. Furthermore, the stick-type substrate 150G is substantially the same as the stick-type substrate 150E according to the fifth configuration example.

[0087] The heating section 121G-1 is substantially the same as the heating section 121E according to the fifth configuration example. The heating section 121G-2 is substantially the same as the heating section 121F according to the sixth configuration example. However, typically, the temperature of the heating section 121G-2 is controlled to be lower than the temperature of the heating section 121G-1. This is because the heat emitted from the heating section 121G-2 is more easily propagated to the other components of the suction device 100G compared to the heat emitted from the heating section 121G-1.

[0088] Although Figure 8 shows an example where the heating unit 121G-2 is arranged on the outer circumference of the holding unit 140G, this configuration example is not limited to this example. For example, the heating unit 121G-2 may be arranged to cover the bottom 143G of the holding unit 140G.

[0089] (4) Eighth Configuration Example The suction device according to this configuration example has a mechanism for holding a substrate containing an aerosol source by sandwiching it. This configuration example will be described below with reference to Figure 9.

[0090] Figure 9 is a schematic diagram illustrating an eighth configuration example of the suction device. As shown in Figure 9, the suction device 100H according to this configuration example includes a power supply unit 111H, a sensor unit 112H, a notification unit 113H, a storage unit 114H, a communication unit 115H, a control unit 116H, a heating unit 121H-1, a heating unit 121H-2, a holding unit 140H, a heat insulating unit 144H-1, a heat insulating unit 144H-2, and an opening / closing mechanism 147. With the stick-shaped substrate 150H held in the holding unit 140H, suction is performed by the user. Each component will be described in order below.

[0091] Each of the power supply unit 111H, sensor unit 112H, notification unit 113H, storage unit 114H, communication unit 115H, and control unit 116H is substantially the same as the corresponding component included in the suction device 100E according to the fifth configuration example. Furthermore, the stick-type substrate 150H is substantially the same as the stick-type substrate 150E according to the fifth configuration example.

[0092] The holding portion 140H has the same configuration as the holding portion 140E according to the fifth configuration example. However, the internal space 141H of the holding portion 140H is realized as a space sandwiched between the first housing 145 and the second housing 146. The holding portion 140H further includes an opening / closing mechanism 147, which is a mechanism for opening and closing the first housing 145 in the direction indicated by arrow 193. The opening / closing mechanism 147 is, for example, a hinge. The holding portion 140H opens and closes the first housing 145 using the opening / closing mechanism 147 to hold the stick-type base material 150H sandwiched between the first housing 145 and the second housing 146.

[0093] The heating units 121H-1 and 121H-2 are substantially the same as the heating unit 121F according to the sixth configuration example. However, the heating unit 121H-1 is located in the first housing 145, and the heating unit 121H-2 is located in the second housing 146.

[0094] The heat insulating sections 144H-1 and 144H-2 are substantially the same as the heat insulating section 144F according to the sixth configuration example. However, the heat insulating section 144H-1 is located in the first housing 145, and the heat insulating section 144H-2 is located in the second housing 146.

[0095] <2.3. Induction Heating Type Suction Devices> Induction heating (IH) type suction devices are suction devices that generate aerosols by induction heating. The configuration examples 9 and 10 described below are examples of configurations for induction heating type suction devices.

[0096] (1) The ninth configuration example The suction device according to this configuration example is a substrate-integrated suction device that generates an aerosol by induction heating. This configuration example will be described below with reference to Figure 10.

[0097] Figure 10 is a schematic diagram illustrating a ninth configuration example of a suction device. As shown in Figure 10, the suction device 100I according to this configuration example includes a power supply unit 110I and a cartridge 120I. The power supply unit 110I and the cartridge 120I are configured to be detachable from each other. Suction by the user is performed with the cartridge 120I attached to the power supply unit 110I.

[0098] As shown in Figure 10, the power supply unit 110I includes a power supply unit 111I, a sensor unit 112I, a notification unit 113I, a storage unit 114I, a communication unit 115I, and a control unit 116I. The cartridge 120I includes a susceptor 161I, an electromagnetic induction source 162I, a liquid induction unit 122I, a liquid storage unit 123I, and a mouthpiece 124I. An air passage 180I is also formed in the cartridge 120I. Each component will be described in order below.

[0099] Each component of the power supply unit 110I, the liquid guide unit 122I, the liquid storage unit 123I, the air passage 180I, and the mouthpiece 124I are substantially identical to the corresponding components included in the suction device 100A according to the first configuration example.

[0100] The susceptor 161I generates heat through electromagnetic induction. The susceptor 161I is made of a conductive material such as metal. The susceptor 161I is positioned in close proximity to the liquid guide section 122I. In the example shown in Figure 10, the susceptor 161I is made of a metal wire and is wrapped around the liquid guide section 122I.

[0101] The electromagnetic induction source 162I generates heat in the susceptor 161I through electromagnetic induction. The electromagnetic induction source 162I is composed of, for example, a coiled wire. When alternating current is supplied to the electromagnetic induction source 162I from the power supply unit 111I, it generates a magnetic field. The electromagnetic induction source 162I is positioned so that the susceptor 161I is superimposed on the generated magnetic field. Therefore, when a magnetic field is generated, eddy currents are generated in the susceptor 161I, and Joule heat is generated. This Joule heat then heats the aerosol source held in the liquid induction unit 122I, causing it to atomize and an aerosol is generated. As an example, power may be supplied and an aerosol may be generated when the sensor unit 112I detects that the user has performed an inhalation. As another example, power may be supplied and an aerosol may be generated when the sensor unit 112I detects that a predetermined user input has been made. Subsequently, when the sensor unit 112I detects that a predetermined user input has been made, the power supply may be stopped. As another example, power may be supplied and an aerosol may be generated during the period when the sensor unit 112I detects that the user has performed an inhalation.

[0102] In addition, the suction device 100I according to this configuration example may have a flavoring cartridge 130 positioned downstream of the cartridge 120I, similar to the suction device 100B according to the second configuration example. In other words, the suction device 100I according to this configuration example may consist of three components: a power supply unit 110I, a cartridge 120I, and a flavoring cartridge 130.

[0103] (2) Tenth Configuration Example The suction device according to this configuration example is an external suction device for a substrate that generates an aerosol by induction heating. This configuration example will be described below with reference to Figure 11.

[0104] Figure 11 is a schematic diagram illustrating a tenth configuration example of the suction device. As shown in Figure 11, the suction device 100J according to this configuration example includes a power supply unit 111J, a sensor unit 112J, a notification unit 113J, a storage unit 114J, a communication unit 115J, a control unit 116J, a susceptor 161J, an electromagnetic induction source 162J, and a holding unit 140J. With the stick-type substrate 150J held in the holding unit 140J, suction is performed by the user. Each component will be described in order below.

[0105] Each of the power supply unit 111J, sensor unit 112J, notification unit 113J, storage unit 114J, communication unit 115J, control unit 116J, and holding unit 140J is substantially the same as the corresponding component included in the suction device 100E according to the fifth configuration example.

[0106] The stick-type substrate 150J has the same configuration as the stick-type substrate 150E according to the fifth configuration example. Furthermore, the stick-type substrate 150J includes a susceptor 161J.

[0107] The susceptor 161J generates heat through electromagnetic induction. The susceptor 161J is made of a conductive material such as metal. For example, the susceptor 161J is a metal piece. The susceptor 161J is placed in close proximity to the aerosol source. In the example shown in Figure 11, the susceptor 161J is included in the base material portion 151J of the stick-type base material 150J.

[0108] The electromagnetic induction source 162J generates heat in the susceptor 161J through electromagnetic induction. The electromagnetic induction source 162J is, for example, made of a coiled wire and is arranged to wrap around the outer circumference of the holding part 140J. When alternating current is supplied to the electromagnetic induction source 162J from the power supply unit 111J, it generates a magnetic field. The electromagnetic induction source 162J is positioned so that the internal space 141J of the holding part 140J is superimposed on the generated magnetic field. Therefore, when a magnetic field is generated while the stick-type substrate 150J is held in the holding part 140J, eddy currents are generated in the susceptor 161J, and Joule heat is generated. This Joule heat then heats and atomizes the aerosol source contained in the stick-type substrate 150J, generating an aerosol. As an example, power may be supplied and an aerosol may be generated when a predetermined user input is detected by the sensor unit 112J. When the temperature of the stick-shaped substrate 150J, which has been inductively heated by the susceptor 161J and the electromagnetic induction source 162J, reaches a predetermined temperature, the user can perform suction. Subsequently, when the sensor unit 112J detects that a predetermined user input has been made, the power supply may be stopped. As another example, power may be supplied and an aerosol may be generated during the period in which the sensor unit 112J detects that the user has performed suction.

[0109] In Figure 11, an example is shown in which the susceptor 161J is included in the base material portion 151J of the stick-type base material 150J, but this example configuration is not limited to this example. For example, the holding portion 140J may perform the function of the susceptor 161J. In this case, the magnetic field generated by the electromagnetic induction source 162J generates eddy currents in the holding portion 140J, which in turn generates Joule heat. This Joule heat then heats and atomizes the aerosol source contained in the stick-type base material 150J, generating an aerosol.

[0110] <2.4. Hybrid Suction Devices> Hybrid suction devices are hybrid-type suction devices equipped with multiple types of heaters.

[0111] (1) Example 11 The suction device according to this example is a suction device that combines the features of both a substrate-integrated suction device and a substrate-external suction device. The 11th example described below is an example of a hybrid type suction device. This example will be described below with reference to Figure 12.

[0112] Figure 12 is a schematic diagram illustrating an eleventh configuration example of the suction device. As shown in Figure 12, the suction device 100K according to this configuration example includes a power supply unit 111K, a sensor unit 112K, a notification unit 113K, a storage unit 114K, a communication unit 115K, a control unit 116K, a liquid induction unit 122K, a liquid storage unit 123K, a heating unit 121K-1, a heating unit 121K-2, a holding unit 140K, and a heat insulating unit 144K. An air passage 180K is also formed in the suction device 100K. Suction is performed by the user with the stick-type substrate 150K held in the holding unit 140K. Each component will be described in order below.

[0113] Each of the power supply unit 111K, sensor unit 112K, memory unit 114K, communication unit 115K, control unit 116K, heating unit 121K-1, liquid induction unit 122K, and liquid storage unit 123K is substantially the same as the corresponding component included in the suction device 100A according to the first configuration example. The heating unit 121K-2 is substantially the same as the heating unit 121E according to the fifth configuration example. The stick-type substrate 150K is substantially the same as the stick-type substrate 150E according to the fifth configuration example.

[0114] The holding portion 140K has the same configuration as the holding portion 140E according to the fifth configuration example. Furthermore, an air outlet hole 182K of the air passage 180 is located at the bottom portion 143K of the holding portion 140K. The internal space 141K of the holding portion 140K and the air passage 180K are connected via the air outlet hole 182.

[0115] The air passage 180K is the passage for air drawn in by the user. The air passage 180K has a tubular structure with an air inlet 181K, which is the entrance for air into the air passage 180K, and an air outlet 182K, which is the exit for air from the air passage 180K, at both ends. As the user draws air in, air flows into the air passage 180K from the air inlet 181K and flows out into the internal space 141K of the holding part 140K from the air outlet 182K. For example, the air inlet 181K can be placed at any position on the suction device 100K. On the other hand, the air outlet 182K can be placed at the bottom 143K of the holding part 140K. A liquid guide part 122K is placed in the middle of the air passage 180K. The aerosol generated by the heating part 121K-1 is mixed with the air that flows in from the air inlet 181K. Next, as the user inhales, the aerosol-air mixture is transported to the internal space 141K of the holding unit 140 via the air outlet 182K, as shown by arrow 190K. The aerosol-air mixture transported to the internal space 141K of the holding unit 140, along with the aerosol generated by the heating unit 121K-2, reaches the user's mouth.

[0116] In this configuration example, instead of heating by the heating unit 121K-1, aerosol generation may be performed by vibration by the vibration unit 127 according to the fourth configuration example, or by induction heating by the susceptor 161I and electromagnetic induction source 162I according to the ninth configuration example. Also, instead of heating by the heating unit 121K-2, aerosol generation may be performed by induction heating by the susceptor 161J and electromagnetic induction source 162K according to the tenth configuration example.

[0117] (2) Example 12 The suction device according to this example comprises a heater for heating a liquid aerosol source and a heater for heating a solid aerosol source, and can generate aerosols by heating both the liquid aerosol source and the solid aerosol source.

[0118] Figure 13 is a schematic diagram illustrating a twelfth configuration example of a suction device. The suction device 100L shown in Figure 13 includes a power supply unit 111L, a sensor unit 112L, a notification unit 113L, a storage unit 114L, a communication unit 115L, a control unit 116L, a liquid induction unit 122L, a liquid storage unit 123L, a heating unit 121L-1, a heating unit 121L-2, a holding unit 140L, and a heat insulating unit 144L.

[0119] An air passage 180L is formed inside the suction device 100L. The air passage 180L functions as a passage for transporting aerosols generated from a liquid aerosol source stored in the liquid storage section 123L to a capsule-type container 130L filled with a solid aerosol source.

[0120] The liquid storage section 123L corresponds to the cartridge 120 mentioned above, and the capsule-type container 130L corresponds to the flavoring cartridge 130 mentioned above. In this embodiment, the user performs suction with the capsule-type container 130L attached to the holding section 140L.

[0121] The power supply unit 111L stores power. The power supply unit 111L then supplies power to each component of the suction device 100L. For example, a rechargeable battery such as a lithium-ion secondary battery is used for the power supply unit 111L. If the power supply unit 111L is a rechargeable battery, it can be charged repeatedly via an external power source connected through a USB cable or the like. If the main unit 110L supports wireless power transmission, the power supply unit 111L can be charged without contact with an external device that transmits power. If the power supply unit 111L is detachable from the main unit 110L of the suction device 100L, a worn-out power supply unit 111L can be replaced with a new one.

[0122] The sensor unit 112L is a device that detects information about various parts of the main body 110L of the apparatus. The sensor unit 112L outputs the detected information to the control unit 116L. The sensor unit 112L may be, for example, a pressure sensor such as a microphone condenser, a flow sensor, or a temperature sensor. This type of sensor unit 112L is used, for example, to detect user inhalation. As another example, the sensor unit 112L is composed of an input device that receives information from the user, such as a button or switch. The sensor unit 112L may also include a button that instructs the start / stop of aerosol generation. Furthermore, the sensor unit 112L outputs the information input by the user to the control unit 116L. In addition, the sensor unit 112L may be, for example, a thermistor. The thermistor, which is the sensor unit 112L, is used, for example, to measure the temperature of the heating unit 121L-2 used to heat the capsule-type container 130L.

[0123] The notification unit 113L is a device that notifies the user of information. The notification unit 113L may be a light-emitting device such as an LED. If the notification unit 113L is a light-emitting device, the light-emitting device is controlled to emit light in a pattern corresponding to the content of the information being notified. For example, when notifying the user that the power supply unit 111L needs charging, when notifying the user that the power supply unit 111L is charging, and when notifying the user of an abnormality, the light-emitting device is controlled to emit light in different patterns. Different light-emitting patterns are concepts that include differences in color, differences in the timing of turning on and off, and differences in brightness when lit.

[0124] Furthermore, the notification unit 113L may be, for example, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates. These devices may be used individually or in combination, and may be used together with the aforementioned light-emitting device, or in place of the light-emitting device. The display device is, for example, a display.

[0125] The memory unit 114L stores various information related to the operation of the suction device 100L. The memory unit 114L is composed of a non-volatile storage medium such as flash memory. The information stored in the memory unit 114L includes, for example, programs executed by the control unit 116L. These programs include the OS (Operating System), firmware, and application programs. The information stored in the memory unit 114L also includes, for example, information necessary for the control unit 116L to control each part.

[0126] The communication unit 115L is a communication interface used to send and receive information with other devices. The communication interface conforms to wired or wireless communication standards. Communication standards include, for example, wireless LAN, wired LAN, mobile communication systems such as 4G and 5G, and Wi-Fi and Bluetooth. The communication unit 115L is used, for example, to display information related to the user's suction on a smartphone or tablet terminal. The communication unit 115L is used, for example, to receive update data for programs stored in the storage unit 114L from a server.

[0127] The control unit 116L functions as both an arithmetic processing unit and a control unit, controlling the operation of each part of the main unit 110L through program execution. The control unit 116L is equipped with electronic circuits such as a CPU microprocessor. The control unit 116L also includes a ROM for storing programs and calculation parameters, and a RAM for temporarily storing parameters that change as needed.

[0128] The control unit 116L controls, for example, power supply from the power supply unit 111L to each unit, charging of the power supply unit 111L, detection of information by the sensor unit 112L, notification of information by the notification unit 113L, storage and retrieval of information by the storage unit 114L, and transmission and reception of information by the communication unit 115L. The control unit 116L also performs processing of information received by the user, processing based on information output from each unit, etc.

[0129] The liquid storage section 123L is a container for storing a liquid aerosol source. The liquid aerosol source may include, for example, polyhydric alcohols such as glycerin and propylene glycol, or liquids such as water. The liquid aerosol source may also contain tobacco raw materials or extracts derived from tobacco raw materials that release flavor components when heated. Furthermore, the liquid aerosol source may contain nicotine.

[0130] The liquid guide section 122L is a component that guides and holds the liquid aerosol source stored in the liquid storage section 123L. The liquid guide section 122L has a structure made by twisting a fibrous material such as glass fiber or a porous material such as porous ceramic. This type of component is also called a wick. Both ends of the liquid guide section 122L are connected to the inside of the liquid storage section 123L. Therefore, the aerosol source stored in the liquid storage section 123L spreads throughout the liquid guide section 122L by the capillary effect.

[0131] The heating unit 121L-1 is an element that heats and atomizes the aerosol source held in the liquid induction unit 122L to generate an aerosol. The heating unit 121L-1 is an example of the first heating unit. The heating unit 121L-1 is not limited to the coil shape shown in Figure 13, but may also be in the shape of a film, blade, or other shapes. The shape of the heating unit 121L-1 varies depending on the heating method, etc. The heating unit 121L-1 is made of any material such as metal or polyimide.

[0132] The heating unit 121L-1 is positioned close to the liquid guide unit 122L. In this embodiment, the heating unit 121L-1 is a metal coil wrapped around the outer surface of the liquid guide unit 122L. The heating unit 121L-1 generates heat when power is supplied from the power supply unit 111L, and heats the aerosol source held in the liquid guide unit 122L to its vaporization temperature. The aerosol source, having reached its vaporization temperature, is released into the air as a gas from the liquid guide unit 122L, but is cooled by the surrounding air and atomized to become an aerosol.

[0133] Power is supplied to the heating unit 121L-1, which heats the liquid aerosol source, for example, in conjunction with the user's inhalation. That is, power is supplied to the heating unit 121L-1 from the start to the end of the user's inhalation, and the power supply to the heating unit 121L-1 is stopped when the user's inhalation ends. Alternatively, power may be supplied to the heating unit 121L-1, which heats the liquid aerosol source, for example, when a specific button is pressed while no aerosol is being generated, and when a specific button is pressed while an aerosol is being generated. The button that instructs the start of aerosol generation and the button that instructs the stop of aerosol generation may be the same button or different buttons.

[0134] The capsule-type container 130L is a container filled with a solid aerosol source. The solid aerosol source may include processed products such as shredded tobacco or tobacco raw materials molded into granules, sheets, or powders that release flavor components when heated. In other words, the solid aerosol source may contain tobacco-derived substances. The solid aerosol source may also contain, for example, nicotine components. Furthermore, the solid aerosol source may also contain non-tobacco-derived substances extracted from plants other than tobacco (e.g., mint, herbs, etc.). In addition, the solid aerosol source may contain, for example, flavoring components such as menthol.

[0135] The holding portion 140L has an internal space 141L into which, for example, a capsule-type container 130L is attached. The holding portion 140L is a cylindrical body having a bottom portion 143L and defines a columnar internal space 141L. A portion of the capsule-type container 130L is held by the holding portion 140L, and the remainder is exposed outside the holding portion 140L. The portion of the capsule-type container 130L that is exposed from the holding portion 140L is used as a mouthpiece 124L. The mouthpiece 124L is held in the mouth of the user who inhales the aerosol.

[0136] The air inlet (i.e., air inlet) for the holding portion 140L is provided, for example, in the bottom portion 143L. The bottom of the capsule-type container 130L has a hole through which air can flow in. Therefore, the air flowing in from the bottom portion 143L passes through the inside of the capsule-type container 130L and reaches the mouthpiece 124L. That is, the mouthpiece 124L becomes the air outlet (i.e., air outlet). Furthermore, the bottom portion 143L is connected to the air outlet hole 182L of the air passage 180L formed inside the main body of the device 110L. Through this air outlet hole 182L, the internal space 141L of the holding portion 140L and the air passage 180L are connected.

[0137] The heating unit 121L-2 generates an aerosol by heating the solid aerosol source filled in the capsule-type container 130L, thereby atomizing it. The heating unit 121L-2 is an example of a second heating unit. The heating unit 121L-2 is made of metal or polyimide, etc. The heating unit 121L-2 is positioned to contact the outer circumferential surface of the metal part of the holding unit 140L. The heating unit 121L-2 generates heat when power is supplied from the power supply unit 111L, and heats the outer circumferential surface of the capsule-type container 130L that is in contact with the metal part of the holding unit 140L. Therefore, the area closest to the outer circumferential surface of the capsule-type container 130L is heated first, and then the heated area spreads toward the center. The aerosol source that reaches the vaporization temperature is vaporized. However, it is cooled by the surrounding air and atomized, becoming an aerosol. Power supply to the heating unit 121L-2 and the heating associated with power supply are controlled by the control unit 116L.

[0138] The heat insulating section 144L is a component that prevents heat transfer from the heating section 121L-2 to other components of the main body 110L of the device. The heat insulating section 144L covers at least the outer surface of the heating section 121L-2. The heat insulating section 144L is made of, for example, vacuum insulating material or aerogel insulating material. Vacuum insulating material refers to insulating material in which heat conduction by gas is reduced to almost zero by wrapping glass wool or silica (silicon powder) etc. in a resin film and creating a high vacuum state.

[0139] As described above, the air passage 180L is an air passage provided inside the main body 110L of the device. The air passage 180L has a tubular structure with an air inlet 181L, which is the air entrance to the air passage 180L, and an air outlet 182L, which is the air exit from the air passage 180L, at both ends. When the user sucks air, air flows into the air passage 180L from the air inlet 181L and flows out to the bottom 143L of the holding part 140L from the air outlet 182L.

[0140] A liquid guide section 122L is positioned in the middle of the air passage 180L. The liquid-derived aerosol generated by heating in the heating section 121L-1 is mixed with air flowing in through the air inlet 181L. Subsequently, the mixed gas of liquid-derived aerosol and air passes through the inside of the capsule-type container 130L and is output from the mouthpiece 124L into the user's oral cavity. In Figure 13, this passage is indicated by the arrow 190L.

[0141] As the liquid-derived aerosol and air mixture passes through the capsule-type container 130L, solid-derived aerosols are added to it. The concentration of solid-derived aerosols increases by combining this with the heating control of the heating unit 121L-2.

[0142] Note that the heating section 121L-2 does not necessarily need to be heated. Even if the heating section 121L-2b is not heated, a solid aerosol source is added as the liquid-derived aerosol passes through the capsule-type container 130L.

[0143] <<3. Example of Terminal Device Configuration>> Below, an example of the configuration of a terminal device, which is one embodiment of the present disclosure, will be described. Figure 14 is a schematic diagram showing an example of the configuration of a terminal device 200 according to this embodiment. As shown in Figure 14, the terminal device 200 includes an input unit 210, an output unit 220, a detection unit 230, a communication unit 240, a storage unit 250, and a control unit 260.

[0144] The input unit 210 has the function of receiving input of various types of information. The input unit 210 may include an input device that receives information from the user. Examples of input devices include buttons, keyboards, touch panels, microphones, and cameras. In addition, the input unit 210 may include various sensors such as image sensors. Furthermore, the input unit 210 may include a sensor capable of reading barcodes, two-dimensional barcodes, etc.

[0145] The output unit 220 has the function of outputting information. The output unit 220 may include an output device that outputs information to the user. Examples of output devices include a display device that displays information, a light-emitting device that emits light, a vibration device that vibrates, and a sound output device that emits sound. An example of a display device is a display or a VR (Virtual Reality) headset. An example of a light-emitting device is an LED (Light Emitting Diode). An example of a vibration device is an eccentric motor. An example of a sound output device is a speaker. The output unit 220 notifies the user of various kinds of information by outputting the information input from the control unit 260.

[0146] The detection unit 230 has the function of detecting information related to the terminal device 200. The detection unit 230 may detect the location information of the terminal device 200. For example, the detection unit 230 receives GNSS (Global Navigation Satellite System) signals from GNSS (Global Navigation Satellite System) satellites (for example, GPS signals from GPS (Global Positioning System) satellites) and detects the location information consisting of the latitude and longitude of the terminal device 200. The detection unit 230 may also detect the movement of the terminal device 200. For example, the detection unit 230 includes a gyro sensor and an accelerometer and detects angular velocity and acceleration.

[0147] The communication unit 240 is a communication interface for sending and receiving information between the terminal device 200 and other devices. The communication unit 240 performs communication in accordance with any wired or wireless communication standard. Examples of such communication standards include those using USB (Universal Serial Bus), Wi-Fi (registered trademark), Bluetooth (registered trademark), NFC (Near Field Communication), or LPWA (Low Power Wide Area).

[0148] The memory unit 250 stores various types of information. The memory unit 250 is composed of a non-volatile storage medium, such as flash memory.

[0149] The control unit 260 functions as an arithmetic processing unit or control unit, and controls the overall operation of the terminal device 200 according to various programs. The control unit 260 is implemented by electronic circuits such as a CPU (Central Processing Unit) or a microprocessor. In addition, the control unit 260 may include a ROM (Read Only Memory) for storing the programs and calculation parameters to be used, and a RAM (Random Access Memory) for temporarily storing parameters that change as needed. The terminal device 200 executes various processes based on the control of the control unit 260. Processing of information input by the input unit 210, output of information by the output unit 220, detection of information by the detection unit 230, transmission and reception of information by the communication unit 240, and storage and retrieval of information by the storage unit 250 are examples of processes controlled by the control unit 260. Other processes executed by the terminal device 200, such as inputting information to each component and processing based on information output from each component, are also controlled by the control unit 260.

[0150] The functions of the control unit 260 may be implemented using an application. This application may be pre-installed or downloaded. Furthermore, the functions of the control unit 260 may be implemented using Progressive Web Apps (PWA).

[0151] <<4. Examples of correspondence between sensing information and graphic information>> Below, an example of the correspondence between sensing information and graphic information, which is one embodiment of this disclosure, will be described.

[0152] Figure 15 is a table showing an example of the correspondence between sensing information and graphic information according to this embodiment. As shown in Figure 15, graphic information is associated with each of the multiple sensing information items. The correspondence between sensing information and graphic information is stored in advance in the storage unit 250 of the terminal device 200.

[0153] The suction device 100 senses various data from the substrate and the user 400 using its sensor unit.

[0154] The sensor unit of the inhalation device 100 is composed of, for example, a pressure sensor such as a condenser microphone, a flow sensor, or a temperature sensor, and acquires information about the generated aerosol. The information about the generated aerosol can be any information related to the generated aerosol, such as the temperature of the aerosol, the amount of nicotine contained in the aerosol, or the amount of aerosol (amount smoked). The sensor unit may also acquire values ​​associated with inhalation by the user 400. The values ​​associated with inhalation by the user 400 are, for example, the number of times the user 400 smokes, the smoking interval, the amount of smoke inhaled per puff, the number of puffs (e.g., average value), and the interval between puffs (e.g., average value). As another example, the sensor unit may be composed of, for example, a capacitance sensor or an infrared sensor, and acquire information about the substrate. The information about the substrate is, for example, the type of substrate (regular or menthol, etc.) and its characteristics (nicotine content, etc.) of the substrate inserted into the inhalation device 100. As yet another example, the sensor unit may be composed of an input device that receives information input from the user 400, such as a button or switch.

[0155] The sensing information sensed by the inhalation device 100 is information that the inhalation device 100 can sense by the sensor unit 112, and is, for example, information about the aerosol generated when the substrate is heated by the heating unit 121. The sensing information can be any information related to the generated aerosol, such as the temperature of the generated aerosol, the taste of the generated aerosol, the amount of the generated aerosol (amount of smoke), and the amount of nicotine contained in the generated aerosol. The taste of the generated aerosol may be calculated, for example, from the concentration per unit of the generated aerosol or the nicotine content per unit of the generated aerosol. The amount of nicotine in the generated aerosol may also be calculated from the concentration per unit of the generated aerosol.

[0156] The sensing information sensed by the inhalation device 100 may also be information about the substrate. Information about the substrate may include, for example, the type and characteristics of the substrate. The type of substrate may indicate, for example, whether the substrate is a regular type, a menthol type, or a type that contains flavor. The characteristics of the substrate may include, for example, the nicotine content contained in the substrate, or information indicating the length and thickness of the substrate. However, the information about the substrate is not limited to these and may include any information. Information about the substrate may also be sensed by the terminal device 200.

[0157] Furthermore, the sensing information sensed by the suction device 100 may change over time. In this case, the suction device 100 acquires multiple pieces of sensing information that change over time. For example, the suction device 100 acquires information about multiple aerosols generated in one suction session as multiple pieces of sensing information that change over time. For example, the suction device 100 acquires the temperature of aerosols generated in one suction session that change over time as multiple pieces of sensing information that change over time. In this way, the suction device 100 may acquire multiple pieces of sensing information of the same type that change over time.

[0158] The terminal device 200 is equipped with an input unit, through which various types of information can be acquired. The input unit of the terminal device 200 is, for example, a sensor capable of reading identification information (e.g., barcodes or two-dimensional barcodes) printed on a substrate or a container that stores the substrate, and can acquire information regarding the type of substrate (regular, menthol, etc.) and its characteristics (nicotine content, etc.). The terminal device 200 can create and display predetermined graphic information by taking into account the acquired information regarding the substrate in addition to the received sensing information.

[0159] Graphic information is, for example, a shape. As shown in Figure 15, a shape, which is graphic information, is associated with each of the multiple sensing information items. Also, as shown in Figure 15, multiple graphic information items may be associated with a single sensing information item.

[0160] As shown in Figure 15, when the sensing information is the temperature of the aerosol, the color information of the graphic may change as the temperature decreases from high to low. In the example in Figure 15, a "dark color" is associated with a "low temperature" of the aerosol. Dark colors include, for example, blue or purple. Also, a "bright color" is associated with a "high temperature" of the aerosol. Bright colors include, for example, red or orange. In the example in Figure 15, as the aerosol temperature transitions from "low" to "high," the color transitions from "dark" to "bright." Note that the graphic information shown in Figure 15 is just one example, and the color information associated with the aerosol temperature can be changed in any way. Also, in the example in Figure 15, there is one color information associated with the aerosol temperature, but there are not limited to one color information, and there may be multiple. Furthermore, although the example in Figure 15 shows the case where the sensing information is the temperature of the aerosol, the sensing information is not limited to the temperature of the aerosol, but may include, for example, the temperature of a heater that heats the substrate. The heater temperature can be sensed from the resistance value of the heating element 121 or from a thermistor capable of measuring the temperature of the heating element 121.

[0161] As shown in Figure 15, in the case of the amount of aerosol smoke for which sensing information is generated, the degree of unevenness of the graphic information (shape) may be associated with increasing smoke volume from a low smoke volume state to a high smoke volume state. In the example in Figure 15, a circular shape with low unevenness is associated with a low smoke volume state. Also, a star-shaped shape with high unevenness is associated with a high smoke volume state. In the example in Figure 15, the degree of unevenness of the associated shape increases as the smoke volume of the aerosol transitions from a low smoke volume state to a high smoke volume state. In the example in Figure 15, as the smoke volume of the aerosol transitions from a low smoke volume state to a high smoke volume state, the associated shape transitions from a circle, octagon, hexagon, pentagon, square, and star shape. Note that the graphic information shown in Figure 15 is just an example, and any shape can be associated according to the amount of smoke volume of the aerosol. Furthermore, while Figure 15 shows graphic information as a shape, it is not limited to shapes; any type of graphic information, such as points, lines, or a predetermined image, may be associated with it.

[0162] Similarly, as shown in Figure 15, in the case of the taste of an aerosol for which sensing information has been generated, the degree of unevenness of the graphic information (shape) may be associated with the taste of the aerosol as it progresses from a weak taste to a strong taste. In the example in Figure 15, a circular shape with low degree of unevenness is associated with a "weak" taste of the aerosol. Also, a star-shaped shape with high degree of unevenness is associated with a "strong" taste of the aerosol. In the example in Figure 15, the degree of unevenness of the associated shape increases as the taste of the aerosol transitions from a "weak" to a "strong" taste.

[0163] Similarly, as shown in Figure 15, in the case of nicotine content in the aerosol from which sensing information is generated, the degree of unevenness of the graphic information (shape) may be associated with increasing nicotine content from a low state to a high state. In the example in Figure 15, a circular shape with low unevenness is associated with a "low" nicotine content. Also, a star-shaped shape with high unevenness is associated with a "high" nicotine content. In the example in Figure 15, the degree of unevenness of the associated shape increases as the nicotine content transitions from a "low" state to a "high" state.

[0164] Similarly, as shown in Figure 15, if the sensing information is an attribute of the substrate, the degree of unevenness of the graphic information, which is a shape, may change according to the attribute of the substrate. In the example in Figure 15, the degree of unevenness of the graphic information, which is a shape, may be associated with increasing menthol levels in the substrate as the menthol level changes from a "weak" state to a "strong" state. The menthol level of the substrate can be calculated, for example, from the amount of menthol component contained in the substrate. The degree of unevenness of the graphic information, which is a shape, may be associated with increasing menthol levels. In the example in Figure 15, a "circular" shape with low unevenness is associated with a "weak" menthol state. Also, a "star" shape with high unevenness is associated with a "strong" menthol state. In the example in Figure 15, the degree of unevenness of the associated shape changes as the menthol level transitions from a "weak" state to a "strong" state.

[0165] The example of the correspondence between sensing information and graphic information shown in Figure 15 is merely an example. The sensing information is not limited to the example shown in Figure 15; it can be any information related to the aerosol generated from the substrate or the substrate itself, such as the degree of flavor (flavor source) contained in the substrate. Similarly, the graphic information is not limited to the example shown in Figure 15; it can be any information, such as a three-dimensional figure, multiple figures, or any image.

[0166] <<5. Example of Heating Profile Configuration>> The control unit 116 controls the operation of the heating unit 121 based on the heating profile. The operation of the heating unit 121 is controlled by controlling the power supply from the power supply unit 111 to the heating unit 121. The heating unit 121 heats the stick-type substrate 150 using power supplied from the power supply unit 111, for example.

[0167] The heating profile is control information for controlling the temperature at which the aerosol source is heated. The heating profile defines parameters related to the temperature at which the aerosol source is heated. An example of the temperature at which the aerosol source is heated is the temperature of the heating unit 121. An example of parameters related to the temperature at which the aerosol source is the target value of the temperature of the heating unit 121 (hereinafter also referred to as the target temperature). The temperature of the heating unit 121 may be controlled to change according to the elapsed time from the start of heating. In that case, the heating profile includes information that defines the time-series change of the target temperature. As another example, the heating profile may include parameters that define the method of supplying power to the heating unit 121 (hereinafter also referred to as power supply parameters). Power supply parameters include, for example, the voltage applied to the heating unit 121, ON / OFF of the power supply to the heating unit 121, or the method of feedback control to be adopted. ON / OFF of the power supply to the heating unit 121 may be considered as ON / OFF of the heating unit 121.

[0168] The control unit 116 controls the operation of the heating unit 121 so that its temperature (hereinafter also referred to as the actual temperature) progresses in a manner similar to the target temperature defined in the heating profile. The heating profile is typically designed to optimize the flavor the user experiences when inhaling the aerosol generated from the stick-type substrate 150. Therefore, by controlling the operation of the heating unit 121 based on the heating profile, the flavor the user experiences can be optimized.

[0169] Temperature control of the heating unit 121 can be achieved, for example, by known feedback control. The feedback control may be, for example, PID control (Proportional-Integral-Differential Controller). The control unit 116 may supply power from the power supply unit 111 to the heating unit 121 in the form of pulses by pulse width modulation (PWM) or pulse frequency modulation (PFM). In this case, the control unit 116 can control the temperature of the heating unit 121 by adjusting the duty cycle or frequency of the power pulse in the feedback control. Alternatively, the control unit 116 may perform simple on / off control in the feedback control. For example, the control unit 116 may perform heating by the heating unit 121 until the actual temperature reaches the target temperature, interrupt heating by the heating unit 121 when the actual temperature reaches the target temperature, and resume heating by the heating unit 121 when the actual temperature falls below the target temperature.

[0170] The temperature of the heating section 121 can be quantified, for example, by measuring or estimating the electrical resistance of the heating section 121 (more precisely, the heat-generating resistor constituting the heating section 121). This is because the electrical resistance of the heat-generating resistor changes with temperature. The electrical resistance of the heat-generating resistor can be estimated, for example, by measuring the voltage drop across the heat-generating resistor. The voltage drop across the heat-generating resistor can be measured by a voltage sensor that measures the potential difference applied to the heat-generating resistor. In another example, the temperature of the heating section 121 can be measured by a temperature sensor such as a thermistor installed near the heating section 121.

[0171] The period from the start to the end of the process of generating aerosols using the stick-type substrate 150 will hereafter be referred to as the heating session. In other words, the heating session is the period during which power supply to the heating unit 121 is controlled based on the heating profile. The start of the heating session is the timing when heating based on the heating profile begins. The end of the heating session is the timing when a sufficient amount of aerosol is no longer generated. The heating session includes a preheating period in the first half and a recommended puffing period in the second half. The recommended puffing period is the period during which a sufficient amount of aerosol is expected to be generated. The preheating period is the period from the start of heating until the start of the recommended puffing period. The heating performed during the preheating period is also referred to as preheating.

[0172] The notification unit 113 may notify the user of information indicating when preheating is complete. For example, the notification unit 113 may notify the user of information indicating the end of preheating before it is completed, or notify the user of information indicating that preheating is complete when it is completed. Notification to the user may be made, for example, by lighting an LED or vibration. The user can then perform puffing immediately after preheating is complete by referring to such notification.

[0173] Similarly, the notification unit 113 may notify the user of information indicating when the recommended puff period is ending. For example, the notification unit 113 may notify the user of information that is giving notice of the end of the recommended puff period before it ends, or notify the user of information indicating that the recommended puff period has ended when it has ended. Notification to the user may be made, for example, by the lighting or vibration of an LED. The user can then use such a notification as a reference to continue puffing until the recommended puff period ends.

[0174] An example of a heating profile will be explained with reference to Figure 16. Figure 16 is a schematic graph showing an example of a heating profile. The horizontal axis of the graph is time. The vertical axis of the graph is temperature. As shown in Figure 16, a heating session may sequentially include a first heating period, a cooling period, and a second heating period. The first heating period is the period after the start of heating during which the temperature of the heating unit 121 rises rapidly and is maintained at a high temperature. The cooling period is the period after the first heating period during which the temperature of the heating unit 121 decreases. The second heating period is the period after the cooling period during which the temperature of the heating unit 121 rises again. In the example shown in Figure 16, the target temperature rapidly rises to around 330°C during the first heating period, then decreases to around 230°C during the cooling period, and then gradually rises to around 300°C during the second heating period. During the cooling period, power supply to the heating unit 121 may be interrupted and heating may be turned OFF. In the example shown in Figure 16, the preheating period is from the start of heating until partway through the first heating period, and the recommended puffing period is from partway through the first heating period until the end of the second heating period.

[0175] <<6. Example of Creating Predetermined Graphic Information>> Below, an example of creating predetermined graphic information, which is one embodiment of the present disclosure, will be described. Predetermined graphic information is created in advance for each of the multiple substrates. For example, predetermined graphic information is created in advance based on the results of sensory evaluation for each of the multiple substrates. Alternatively, it may be created in advance for each of the multiple heating profiles. For example, predetermined graphic information may be created in advance based on sensing information sensed in advance by the suction device 100. Predetermined graphic information is created in advance, for example, based on graphic information associated with each of the sensing pieces of information sensed regarding aerosols generated by heating the substrate. The method for creating predetermined graphic information based on sensing information will be described later.

[0176] The timing at which the predetermined graphic information is created can be any timing as long as it is before the terminal device 200 displays the multiple predetermined graphic information. The terminal device 200 receives the predetermined graphic information that has been created in advance from an external device (for example, a server device 500) via the communication unit 240.

[0177] The predetermined graphic information may be created in advance, for example, based on sensing information sensed by each of the multiple suction devices 100. Figure 17 is a schematic diagram showing an example of the configuration of the communication system 20 according to this embodiment when creating the predetermined graphic information. The example in Figure 17 is an example of the configuration of the communication system 20 when the predetermined sensing information is created based on sensing information sensed by each of the multiple suction devices 100.

[0178] As shown in Figure 17, the communication system 20 includes a plurality of suction devices 100 and a server device 500. Each of the plurality of suction devices 100 can communicate with the server device 500 via the network 300.

[0179] As shown in Figure 17, each of the users 400A, 400B, 400C, 400D, and 400E can use each of the suction devices 100_A, 100_B, 100_C, 100_D, and 100_E. Each of the suction devices 100_A, 100_B, 100_C, 100_D, and 100_E acquires sensing information that senses information about the aerosol generated by heating the substrate. Each of the suction devices 100_A, 100_B, 100_C, 100_D, and 100_E transmits the acquired sensing information to the server device 500. In the example in Figure 17, an example with five suction devices 100 is shown, but the number of suction devices 100 is not limited to five; there can be any number of suction devices 100, such as 100, 1000, or 10000.

[0180] The multiple inhalation devices 100 from which the server device 500 acquires sensing information may be inhalation devices 100 used by a predetermined user 400. The server device 500 may acquire sensing information from inhalation devices 100 used by, for example, experts with specialized knowledge regarding the taste of tobacco. The server device 500 may also acquire sensing information from inhalation devices 100 used by, for example, users 400 of a predetermined age group, users residing in a predetermined region or country, or users of a predetermined gender.

[0181] Furthermore, if predetermined graphic information is created in advance based on the results of sensory evaluations for each of multiple substrates, the participants in the sensory evaluation may be selected from users belonging to a predetermined group. The participants in the sensory evaluation may be selected from a group of experts with specialized knowledge regarding, for example, the taste of tobacco. Alternatively, the participants in the sensory evaluation may be selected from general users with general knowledge about tobacco.

[0182] The server device 500 creates predetermined graphic information based on sensing information received from each of the multiple suction devices 100. The server device 500 pre-creates predetermined graphic information based on graphic information associated with each of the sensing information obtained by sensing information about aerosols generated by heating the substrate. In the example shown in Figure 17, the server device 500 creates the predetermined graphic information, but the server device 500 is not the only device that creates the predetermined graphic information; any device, such as a terminal device 200, may do so.

[0183] The server device 500 creates predetermined graphic information based on sensing information obtained by averaging the sensing information received from each of the multiple suction devices 100. Alternatively, the server device 500 may create predetermined graphic information based on the median sensing information among the sensing information received from each of the multiple suction devices 100. Furthermore, the server device 500 may create predetermined graphic information based on the mode sensing information among the sensing information received from each of the multiple suction devices 100. The server device 500 may also create predetermined graphic information using a portion of the sensing information received from each of the multiple suction devices 100.

[0184] Figure 18 is a table showing an example of the creation of predetermined graphic information according to this embodiment. The predetermined graphic information is created, for example, based on graphic information associated with each of the sensing pieces of information sensed regarding aerosols generated by heating a substrate. The sensing information used by the server device 500 to create the predetermined graphic is the average value, median, mode, etc., of the sensing information received from each of the multiple suction devices 100.

[0185] The server device 500 determines graphic information based on multiple sensing information. First, the server device 500 determines graphic information for each of the multiple sensing information based on the correspondence relationship illustrated in Figure 15. Next, the server device 500 creates at least one predetermined graphic information based on the multiple graphic information determined for each of the multiple sensing information.

[0186] As illustrated in Figure 18, the server device 500 determines graphic information for each of the multiple sensing information based on the correspondence relationship illustrated in Figure 15. As illustrated in Figure 18, the server device 500 determines a "bright color" as graphic information when the temperature of the sensed aerosol is "high." Also, as illustrated in Figure 18, the server device 500 determines a "star shape" as graphic information when the amount of smoke from the sensed aerosol is "high." Furthermore, as illustrated in Figure 18, the server device 500 determines a "pentagon" as graphic information when the flavor of the sensed aerosol is "medium." In addition, as illustrated in Figure 18, the server device 500 determines a "circle" as graphic information when the sensed nicotine content is "low." Also, as illustrated in Figure 18, the server device 500 determines a "circle" as graphic information when the sensed menthol level is "weak."

[0187] As illustrated in Figure 18, the server device 500 creates at least one predetermined graphic information based on multiple graphic information determined for each of the multiple sensing information. As illustrated in Figure 18, the server device 500 creates "bright color" and "octagon" as predetermined graphic information based on "bright color," "star shape," "pentagon," "circle," and "circle." As illustrated in Figure 18, since there is only one color information as graphic information, the server device 500 uses "bright color" as the predetermined graphic information. Also, since there are multiple shapes as graphic information, the server device 500 uses a shape that is a combination of them or an average of them as predetermined graphic information. As illustrated in Figure 18, since there are multiple shape information such as "star shape," "pentagon," "circle," and "circle," the "octagon" which is created by combining these or is an average shape of the multiple shapes is used as the predetermined graphic.

[0188] The server device 500 may create predetermined graphic information based on at least one of a plurality of graphic information determined for each of the plurality of sensing information. For example, the server device 500 may determine a "star shape," which is graphic information determined from the fact that the amount of smoke of the sensed aerosol is "large," as predetermined graphic information. Alternatively, the server device 500 may create predetermined graphic information by combining the plurality of graphic information determined for each of the plurality of sensing information. For example, the server device 500 may create "bright color" and "pentagon" as predetermined graphic information from "bright color," which is graphic information determined from the fact that the temperature of the sensed aerosol is "high," and "pentagon," which is graphic information determined from the fact that the taste of the sensed aerosol is "medium."

[0189] Furthermore, the server device 500 may, for example, assign priorities to multiple sensing information and create predetermined graphic information by taking into account the priorities of the multiple graphic information determined for each of the multiple sensing information. In the example in Figure 18, priorities may be assigned to the multiple sensing information in the order of decreasing smoke volume, flavor, nicotine content, and menthol. In this case, the server device 500 may create predetermined graphic information based on the graphic information corresponding to the sensing information determined based on the priorities. For example, the server device 500 may create predetermined graphic information based on the graphic information corresponding to the sensing information with a higher priority. The server device 500 may also create predetermined graphic information by taking into account a coefficient according to the priority.

[0190] The predetermined graphic information may be created in advance based on the results of sensory evaluation for each of the multiple substrates. In this case, the server device 500 determines graphic information for each of the sensory evaluation results for each of the multiple substrates based on the correspondence relationship illustrated in Figure 15. The server device 500 then creates at least one predetermined graphic information based on the multiple graphic information determined for each of the multiple sensing information.

[0191] Furthermore, the server device 500 may create predetermined graphic information based on at least one of a plurality of graphic information determined for each of the sensory evaluation results for each of the plurality of substrates. In addition, the server device 500 may assign a priority to each of the sensory evaluation results for each of the plurality of substrates, and create predetermined graphic information by taking the priority into account for the plurality of graphic information determined for each of the sensory evaluation results for each of the plurality of substrates.

[0192] <<7. Example of Displaying Predetermined Graphic Information>> Below, an example of displaying predetermined graphic information, which is one embodiment of the present disclosure, will be described. The output unit 220 (display device) of the terminal device 200 displays a plurality of predetermined graphic information that has been prepared in advance. The terminal device 200 displays a plurality of predetermined graphic information, each containing at least one graphic, on the output unit 220 (display device). The terminal device 200 also receives a plurality of predetermined graphic information from, for example, the server device 500 and displays the received plurality of predetermined graphic information.

[0193] Figure 19 is a schematic diagram illustrating an example of the display of predetermined graphic information according to this embodiment. As illustrated in Figure 19, the output unit 220 (display device) of the terminal device 200 displays a plurality of predetermined graphic information. In the display example of Figure 19, the plurality of predetermined graphic information is created for each of the plurality of heating profiles. Even with the same substrate, it is expected that different heating profiles used for heating will result in different flavors, smoke volume, and temperatures. Therefore, in the display example of Figure 19, predetermined graphic information is created for each of the plurality of heating profiles that heat the same substrate. The output unit 220 (display device) of the terminal device 200 then displays a plurality of predetermined graphics corresponding to each of the plurality of heating profiles.

[0194] Furthermore, multiple predetermined graphic information may be created for each of the multiple substrates. Even with the same heating profile, different substrates are expected to result in different flavors, smoke volumes, and temperatures. Therefore, predetermined graphic information is created for each of the multiple substrates heated with the same heating profile. The output unit 220 (display device) of the terminal device 200 may then display multiple predetermined graphics corresponding to each of the multiple substrates heated with the same heating profile.

[0195] Furthermore, multiple predetermined graphic information may be created for each of the multiple substrates and for each of the multiple heating profiles. For each substrate, predetermined graphic information is created for each of the multiple heating profiles. In this case, the output unit 220 (display device) of the terminal device 200 may display multiple predetermined graphics for each of the multiple substrates or for each of the multiple heating profiles. Alternatively, the output unit 220 (display device) of the terminal device 200 may randomly display the multiple predetermined graphic information created for each of the multiple heating profiles for each of the multiple substrates.

[0196] As illustrated in Figure 19, the terminal device 200 displays a first predetermined graphic information 601 corresponding to the first heating profile. For example, the terminal device 200 displays an "octagon" graphic as the first predetermined graphic information 601. The user 400 visually inspects the predetermined "octagon" graphic displayed on the terminal device 200 and, based on the correspondence shown in Figure 15, can understand that the characteristics of the aerosol generated from the substrate correspond to at least one of the following: low temperature, low smoke volume, weak flavor, low nicotine content, and weak menthol.

[0197] Furthermore, as illustrated in Figure 19, the terminal device 200 displays a second predetermined graphic information 602 corresponding to the second heating profile. For example, the terminal device 200 displays a "square" as the second predetermined graphic information 602. The user 400 visually inspects the predetermined graphic of a "square" displayed on the terminal device 200 and, based on the correspondence shown in Figure 15, can understand that the characteristics of the aerosol generated from the substrate correspond to at least one of the following: slightly high temperature, slightly high smoke volume, slightly strong flavor, slightly high nicotine content, and slightly strong menthol.

[0198] Furthermore, as illustrated in Figure 19, the terminal device 200 displays a third predetermined graphic information 603 corresponding to the third heating profile. For example, the terminal device 200 displays a "star shape" as the third predetermined graphic information 603. The user 400 visually perceives the predetermined graphic "star shape" displayed on the terminal device 200 and, based on the correspondence shown in Figure 15, can understand that the characteristics of the aerosol generated from the substrate correspond to at least one of the following: high temperature, large amount of smoke, strong flavor, high nicotine content, and strong menthol.

[0199] Thus, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate by visually viewing a plurality of predetermined graphic information displayed on the terminal device 200. Based on the understood aerosol characteristics, the user 400 can select at least one predetermined graphic information and receive a heating profile corresponding to the selected predetermined graphic information. Therefore, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate and select the heating profile to receive, thereby improving the quality of the user experience.

[0200] Furthermore, if multiple predetermined graphic information is created for each of the multiple substrates, the terminal device 200 may display information about the substrate itself, such as the type of substrate, based on the predetermined graphic information selected by the user. Subsequently, the terminal device 200 may display a substrate itself or a type of substrate recommended to the user based on the predetermined graphic information selected by the user. In this way, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate and obtain information about recommended substrates, thereby further improving the quality of the user experience.

[0201] Furthermore, if multiple predetermined graphic information is created for each of the multiple substrates and for each of the multiple heating profiles, the terminal device 200 may, in addition to transmitting information regarding the heating of the substrate, such as the heating temperature and heating profile of the substrate, to the suction device 100 based on the predetermined graphic information selected by the user, also display the substrate itself or the type of substrate recommended to the user based on the predetermined graphic information selected by the user. In this way, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate, select the heating profile to receive, and also understand information on recommended substrates, thereby further improving the quality of the user experience.

[0202] Furthermore, each of the multiple predetermined graphic information pieces created and displayed by the terminal device 200 may change over time. Figure 20 is a schematic diagram illustrating another example of the display of the predetermined graphic information according to this embodiment. The other display example shown in Figure 20 is an example of a display where each of the multiple predetermined graphic information pieces displayed on the terminal device 200 changes over time.

[0203] As shown in Figure 20, the first predetermined graphic information 601 displayed on the terminal device 200 changes in the order of "star shape," "octagon," and "star shape" over time. The user 400 can, for example, understand, based on the correspondence shown in Figure 15, that the aerosol corresponding to the first predetermined graphic information 601 initially has a strong flavor, then the flavor weakens immediately afterward, and then the flavor becomes strong again. The user 400 can also, for example, understand, based on the correspondence shown in Figure 15, that the aerosol corresponding to the first predetermined graphic information 601 initially produces a lot of smoke, then the smoke volume decreases immediately afterward, and then the smoke volume becomes strong again.

[0204] As shown in Figure 20, the second predetermined graphic information 602 displayed on the terminal device 200 changes in the order of "star shape," "circle," and "square" over time. The user 400 can, for example, understand, based on the correspondence shown in Figure 15, that the aerosol corresponding to the second predetermined graphic information 602 has, for example, a strong taste initially, then a weaker taste immediately afterward, and then a slightly stronger taste. The user 400 can also, for example, understand, based on the correspondence shown in Figure 15, that the aerosol corresponding to the second predetermined graphic information 602 has, for example, a large amount of smoke initially, then a small amount of smoke immediately afterward, and then a slightly stronger amount of smoke.

[0205] As shown in Figure 20, the third predetermined graphic information 603 displayed on the terminal device 200 changes in the order of "square," "hexagon," and "square" over time. The user 400 can, for example, understand, based on the correspondence shown in Figure 15, that the aerosol corresponding to the third predetermined graphic information 603 has, for example, a slightly stronger taste initially, then a slightly weaker taste immediately afterward, and then a slightly stronger taste again. The user 400 can also, for example, understand, based on the correspondence shown in Figure 15, that the aerosol corresponding to the third predetermined graphic information 603 has, for example, a slightly larger amount of smoke initially, then a slightly smaller amount of smoke immediately afterward, and then a slightly stronger amount of smoke again.

[0206] In this way, the user 400 can understand that the aerosol generated from the substrate changes over time by visualizing predetermined graphic information that changes over time. Based on the characteristics of the aerosol that the user 400 has understood, the user 400 can select at least one predetermined graphic information and receive a heating profile corresponding to the selected predetermined graphic information. Therefore, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate by visualizing predetermined graphic information and select a heating profile to receive, without actually inhaling the aerosol generated from the substrate, thus improving the quality of the user experience.

[0207] Furthermore, the predetermined graphic information may be created for each of the multiple substrates. In this case, the terminal device 200 can receive and display information about the substrate corresponding to the predetermined graphic information selected by the user. In this way, in the communication system 10, the user 400 can select a substrate by visually viewing the predetermined graphic information without actually inhaling the aerosol generated from the substrate, thereby understanding the characteristics of the aerosol generated from the substrate and confirming information about the substrate corresponding to the selected predetermined graphic information. This makes it possible to further improve the quality of the user experience.

[0208] Furthermore, multiple predetermined graphic information may be created for each of the multiple substrates and for each of the multiple heating profiles. In this case, in addition to transmitting information regarding the heating of the substrate, such as the heating temperature and heating profile of the substrate, to the suction device 100 based on the predetermined graphic information selected by the user, the terminal device 200 can also display the substrate itself or the type of substrate that it recommends to the user based on the predetermined graphic information selected by the user. In this way, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate, select the heating profile to receive, and also understand information on recommended substrates, thereby improving the quality of the user experience.

[0209] <<8. Example of Communication System Processing>> Below, an example of a system including a suction device 100 and a terminal device 200, which is one embodiment of the present disclosure, will be described.

[0210] Figure 21 is a sequence diagram showing an example of processing in a system including a suction device 100, a terminal device 200, and a server device 500 in one embodiment of the present disclosure. The sequence diagram illustrated in Figure 21 is an example of processing in the communication system 10 when a user selects a heating profile based on the characteristics of aerosols generated from each of a plurality of substrates, and the suction device 100 receives the selected heating profile.

[0211] In step 1001, the output unit 220 of the terminal device 200 displays a plurality of predetermined graphic information on the display device. For example, the output unit 220 of the terminal device 200 displays an "octagon," a "square," and a "star" as a plurality of predetermined graphic information, as illustrated in Figure 19.

[0212] In step 1002, the input unit 210 of the terminal device 200 accepts the user 400's selection for at least one of a plurality of predetermined graphic information displayed. For example, the input unit 210 of the terminal device 200 selects the predetermined graphic information "octagon".

[0213] In step 1003, the communication unit 240 of the terminal device 200 requests the server device 500 for a heating profile corresponding to predetermined graphic information selected by the user 400. For example, the communication unit 240 of the terminal device 200 requests the server device 500 for a heating profile corresponding to predetermined graphic information of an "octagon".

[0214] In step 1004, the server device 500 identifies the heating profile requested by the terminal device 200 from among a plurality of stored heating profiles.

[0215] In step 1005, the server device 500 transmits the identified heating profile to the terminal device 200.

[0216] In step 1006, the communication unit 240 of the terminal device 200 transmits the heating profile received from the server device 500 to the suction device 100.

[0217] In step 1007, the communication unit 115 of the suction device 100 receives the heating profile received from the terminal device 200. The storage unit 114 of the suction device 100 stores the received heating profile.

[0218] In step 1008, the sensor unit 112 of the suction device 100 receives an operation from the user 400 to start heating. The operation to start heating is, for example, by the user 400 inserting the substrate into the suction device 100, or by pressing the button which is the sensor unit 112 of the suction device 100 for a predetermined time or a predetermined number of times.

[0219] In step 1009, the control unit 116 of the suction device 100 starts heating control of the heating unit 121. As a result, the control unit 116 of the suction device 100 starts generating an aerosol from the substrate. In this case, the control unit 116 controls the operation of the heating unit 121 based on the heating profile received in step 1007.

[0220] Thus, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate by visually viewing a plurality of predetermined graphic information displayed on the terminal device 200. Based on the understood aerosol characteristics, the user 400 can select at least one predetermined graphic information and receive a heating profile corresponding to the selected predetermined graphic information. Therefore, in the communication system 10, the user 400 can understand the characteristics of the aerosol generated from the substrate and select the heating profile to receive, thereby improving the quality of the user experience.

[0221] The predetermined graphic information may be created for each of the multiple substrates. In this case, in step 1003 of Figure 21, the communication unit 240 of the terminal device 200 requests the server device 500 for information about the substrate corresponding to the predetermined graphic information selected by the user 400. For example, the communication unit 240 of the terminal device 200 requests the server device 500 for information about the substrate corresponding to the predetermined graphic information of "octagon". Then, in step 1004, the server device 500 identifies the information about the substrate requested by the terminal device 200 from the information about the substrates it stores. Then, in step 1005, the server device 500 transmits the identified information about the substrate to the terminal device 200. The terminal device 200 displays the received information about the substrate.

[0222] Thus, in the communication system 10, the user 400 can select a substrate by visually viewing predetermined graphic information without actually inhaling the aerosol generated from the substrate, thereby understanding the characteristics of the aerosol generated from the substrate. Furthermore, the user can confirm information about the substrate corresponding to the selected predetermined graphic information, thereby improving the quality of the user experience.
