Additionally, the inhalation device can receive the heating profile based on the user's evaluation from an external source and use the heating profile to control the heating process of the matrix (also referred to herein as an "aerosol source"). Therefore, the inhalation device can perform heating control of the matrix and generate an aerosol according to the heating profile provided based on the user's evaluation. Thus, in one embodiment of this disclosure, the inhalation device can generate an aerosol with a user-preferred smoking flavor, smoke volume, temperature, etc., thereby further improving the quality of the user experience.

[0041] <<1. Configuration of the inhalation device>>

[0042] An example configuration of the inhalation device according to an embodiment of this disclosure will now be described.

[0043] An inhalation device is a device for generating a substance for a user to inhale. In the following text, the substance generated by an inhalation device will be described as an aerosol. Alternatively, the substance generated by an inhalation device may be a gas.

[0044] (1) First configuration example

[0045] Figure 1 This is a schematic diagram illustrating a first configuration example of the inhalation device. (As shown) Figure 1 As shown, the inhalation device 100A according to this configuration example includes a power supply unit 110, a cartridge 120, and a flavored cartridge 130. The power supply unit 110 includes a power supply unit 111A, a sensor unit 112A, a notification unit 113A, a memory unit 114A, a communication unit 115A, and a control unit 116A. The cartridge 120 includes a heating unit 121A, a liquid guiding section 122, and a liquid storage section 123. The flavored cartridge 130 includes a flavor source 131 and a mouthpiece 124. An airflow path 180 is formed in the cartridge 120 and the flavored cartridge 130.

[0046] Power supply unit 111A stores electricity. Power supply unit 111A then supplies power to each component of inhalation device 100A according to control executed by control unit 116A. Power supply unit 111A may be configured, for example, by a rechargeable battery (such as a lithium-ion secondary battery).

[0047] Sensor unit 112A acquires various types of information related to inhalation device 100A. As an example, sensor unit 112A is configured with a pressure sensor (such as a capacitive microphone, flow sensor, or temperature sensor) and acquires values ​​associated with the user's inhalation. As another example, sensor unit 112A is configured with an input device (such as a button or switch) for accepting information input from the user.

[0048] The notification unit 113A notifies the user of information. For example, the notification unit 113A may be configured as a light-emitting device that emits light, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates.

[0049] The memory unit 114A stores various types of information for operating the suction device 100A. For example, the memory unit 114A is configured with a non-volatile storage medium (such as flash memory).

[0050] The communication unit 115A is a communication interface capable of performing communications compliant with any wired or wireless communication standard. Examples of communication standards that can be used include those employing Wi-Fi (registered trademark), Bluetooth (registered trademark), BLE (Bluetooth Low Energy) (registered trademark), NFC (Near Field Communication), or LPWA (Low Power Wide Area).

[0051] The control unit 116A serves as an arithmetic processing and control device, and controls the overall operation within the inhalation device 100A according to various programs. For example, the control unit 116A is implemented by a CPU (central processing unit) or electronic circuitry (such as a microprocessor).

[0052] The liquid storage section 123 stores an aerosol source. The aerosol source is atomized to generate an aerosol. For example, the aerosol source is a polyol (such as glycerol or propylene glycol) or a liquid (such as water). The aerosol source may include tobacco-derived or non-tobacco-derived flavor components. If the inhalation device 100A is a medical inhaler (such as a nebulizer), the aerosol source may include a drug.

[0053] The liquid guiding section 122 guides and contains the aerosol source from the liquid storage section 123, which is a liquid stored in the liquid storage section 123. For example, the liquid guiding section 122 is a wicking element formed of a twisted fibrous material (such as glass fiber) or a porous material (such as porous ceramic). In this case, the aerosol source stored in the liquid storage section 123 is guided by the capillary action of the wicking element.

[0054] Heating unit 121A heats the aerosol source to atomize it, thereby generating an aerosol. Figure 1 In the example shown, heating unit 121A is configured as a coil wound around liquid guiding portion 122. When heating unit 121A generates heat, an aerosol source held in liquid guiding portion 122 is heated and atomized, thereby generating an aerosol. Heating unit 121A generates heat when supplied with power from power supply unit 111A. For example, power can be supplied when sensor unit 112A detects that the user has begun inhalation and / or has entered predetermined information. Then, power supply can be stopped when sensor unit 112A detects that the user has finished inhaling and / or has entered predetermined information.

[0055] Flavor source 131 is a component used to impart flavor components to an aerosol. Flavor source 131 may include tobacco-derived or non-tobacco-derived flavor components.

[0056] Airflow path 180 is the flow path for air inhaled by the user. Airflow path 180 has a tubular structure with an air inlet 181 and an air outlet 182 at both ends. The air inlet is the entrance for air into airflow path 180, and the air outlet is the exit for air leaving airflow path 180. Midway through airflow path 180, a liquid guide portion 122 is located on the upstream side (closer to the air inlet 181), while a flavor source 131 is located on the downstream side (closer to the air outlet 182). When inhaled by the user, air flowing in through the air inlet 181 mixes with the aerosol generated by heating unit 121A and is conveyed through flavor source 131 to air outlet 182, as indicated by arrow 190. As the aerosol-air mixture passes through flavor source 131, flavor components contained in flavor source 131 are added to the aerosol.

[0057] The mouthpiece 124 is a component that is held in the user's mouth during inhalation. An air outlet 182 is provided in the mouthpiece 124. The user holds the mouthpiece 124 in their mouth and inhales, allowing a mixture of aerosol and air to be drawn into the oral cavity.

[0058] The configuration examples of the inhalation device 100A have been described above. Of course, the inhalation device 100A is not limited to the configurations described above, and can adopt various configurations, such as those shown below by way of example.

[0059] As an example, the inhalation device 100A does not need to include a flavored tobacco cartridge 130. In this case, the tobacco cartridge 120 is provided with a mouthpiece 124.

[0060] As another example, the inhalation device 100A may include multiple types of aerosol sources. Multiple types of aerosols generated from these sources can mix within the airflow path 180 to induce a chemical reaction, thereby further generating other types of aerosols.

[0061] Furthermore, the means for atomizing the aerosol source is not limited to heating performed by the heating unit 121A. For example, the means for atomizing the aerosol source may be vibration atomization or induction heating.

[0062] (2) Second configuration example

[0063] Figure 2 This is a schematic diagram illustrating a second configuration example of the inhalation device. (As shown) Figure 2 As shown, the inhalation device 100B according to this configuration example includes a power supply unit 111B, a sensor unit 112B, a notification unit 113B, a memory unit 114B, a communication unit 115B, a control unit 116B, a heating unit 121B, a receiving portion 140, and a heat insulation portion 144.

[0064] The power supply unit 111B, sensor unit 112B, notification unit 113B, memory unit 114B, communication unit 115B, and control unit 116B are each substantially the same as the corresponding components included in the inhalation device 100A according to the first configuration example.

[0065] The receiving portion 140 has an internal space 141 and holds the rod-shaped matrix 150, while a portion of the rod-shaped matrix 150 is housed within the internal space 141. The receiving portion 140 has an opening 142 that allows communication between the internal space 141 and the outside, and houses the rod-shaped matrix 150 inserted into the internal space 141 through the opening 142. For example, the receiving portion 140 is a cylindrical body that includes the opening 142 and a bottom portion 143 serving as a bottom surface, and this receiving portion defines the cylindrical internal space 141. An airflow path for supplying air to the internal space 141 is connected to the receiving portion 140. For example, an air inlet is provided on the side of the suction device 100B, which is an inlet for air to enter the airflow path. For example, an air outlet is provided on the bottom portion 143, which is an outlet for air to exit from the airflow path to the internal space 141.

[0066] The stick-shaped matrix 150 includes a matrix portion 151 and a mouthpiece portion 152. The matrix portion 151 contains an aerosol source. The aerosol source includes tobacco-derived or non-tobacco-derived flavor components. If the inhalation device 100B is a medical inhaler (such as a nebulizer), the aerosol source may include a drug. For example, the aerosol source may be a liquid containing tobacco-derived or non-tobacco-derived flavor components, such as water or a polyol (e.g., glycerol or propylene glycol), or it may be a solid containing tobacco-derived or non-tobacco-derived flavor components. With the stick-shaped matrix 150 held in the receiving portion 140, at least a portion of the matrix portion 151 is contained in the internal space 141, and at least a portion of the mouthpiece portion 152 protrudes from the opening 142. Thus, when a user takes the mouthpiece portion 152 protruding from the opening 142 into their mouth and inhales, air flows into the internal space 141 via an airflow channel not depicted in the figures and reaches the user's mouth along with the aerosol generated from the matrix portion 151.

[0067] exist Figure 2 In the example shown, the heating unit 121B has a membrane-like form and is arranged to cover the outer circumference of the receiving portion 140. Thus, when the heating unit 121B generates heat, the matrix portion 151 of the rod-shaped matrix 150 is heated from the outer periphery, thereby generating an aerosol.

[0068] The heat insulation portion 144 prevents heat from being transferred from the heating unit 121B to other components. For example, the heat insulation portion 144 is made of vacuum insulation material or aerogel insulation material.

[0069] The configuration examples of the inhalation device 100B have been described above. Of course, the inhalation device 100B is not limited to the configurations described above, and can adopt various configurations, such as those shown below by way of example.

[0070] As an example, the heating unit 121B can be configured to have a blade-like form and can be arranged to protrude from the bottom portion 143 of the receiving portion 140 into the internal space 141. In this case, the blade-like heating unit 121B is inserted into the matrix portion 151 of the rod-shaped matrix 150 and heated from the interior of the matrix portion 151 of the rod-shaped matrix 150. As another example, the heating unit 121B can be arranged to cover the bottom portion 143 of the receiving portion 140. Furthermore, the heating unit 121B can be configured as a combination of two or more of a first heating unit covering the outer periphery of the receiving portion 140, a blade-like second heating unit, and a third heating unit covering the bottom portion 143 of the receiving portion 140.

[0071] As another example, the receiving portion 140 may include an opening and closing mechanism (such as a hinge) for opening and closing a portion of the housing forming the internal space 141. Thus, by opening and closing the housing, the receiving portion 140 can receive and hold the rod-shaped substrate 150 that has been inserted into the internal space 141. In this case, a heating unit 121B may be provided on the holding portion of the receiving portion 140, and can heat the rod-shaped substrate 150 while pressing it.

[0072] Furthermore, the means for atomizing the aerosol source is not limited to heating by the heating unit 121B. For example, the means for atomizing the aerosol source can be induction heating. In this case, the inhalation device 100B includes at least an electromagnetic induction source (such as a coil) for generating a magnetic field, instead of the heating unit 121B. A sensor for generating heat by means of induction heating can be provided in the inhalation device 100B or can be included in the rod-shaped matrix 150.

[0073] Furthermore, the inhalation device 100B may additionally include a heating unit 121A, a liquid guiding portion 122, a liquid storage portion 123, and an airflow path 180, according to the first configuration example, and the airflow path 180 may supply air to the interior space 141. In this case, the mixed fluid of aerosol and air generated by the heating unit 121A flows into the interior space 141 and further mixes with the aerosol generated by the heating unit 121B, reaching the user's mouth.

[0074] It should be noted that, in the following text, the inhalation device 100A and inhalation device 100B described above will also be referred to as "inhalation device 100" without distinction. Similarly, power supply unit 111A and power supply unit 111B may be referred to as "power supply unit 111", sensor unit 112A and sensor unit 112B may be referred to as "sensor unit 112", notification unit 113A and notification unit 113B may be referred to as "notification unit 113", memory unit 114A and memory unit 114B may be referred to as "memory unit 114", communication unit 115A and communication unit 115B may be referred to as "communication unit 115", control unit 116A and control unit 116B may be referred to as "control unit 116", and heating unit 121A and heating unit 121B may be referred to as "heating unit 121".

[0075] <<2. User Terminal Configuration>>

[0076] A configuration example of a user terminal according to an embodiment of this disclosure will now be described.

[0077] Figure 3 This is a block diagram illustrating a configuration example of a user terminal 200 according to an embodiment. Figure 3 As shown, the user terminal 200 includes an input unit 210, an output unit 220, a detection unit 230, a communication unit 240, a memory unit 250, and a control unit 260.

[0078] Input unit 210 has the function of receiving various types of information input. Input unit 210 may include an input device for receiving information input from a user. Examples of input devices include buttons, keyboards, touch panels, and microphones. Alternatively, input unit 210 may include various types of sensors, such as image sensors.

[0079] Output unit 220 has the function of outputting information. Output unit 220 may include an output device for outputting information to a user. Examples of output devices include: a display device for displaying information, a light-emitting device for emitting light, a vibration device for vibrating, and a sound output device for outputting sound. A display is an example of a display device. A light-emitting diode (LED) is an example of a light-emitting device. An eccentric motor is an example of a vibration device. A speaker is an example of a sound output device. Output unit 220 outputs information input from control unit 260 to notify the user of that information.

[0080] The detection unit 230 has the function of detecting information related to the user terminal 200. The detection unit 230 can detect the location information of the user terminal 200. For example, the detection unit 230 receives GNSS signals from GNSS (Global Navigation Satellite System) satellites (e.g., GPS signals from GPS (Global Positioning System) satellites) and detects location information including the longitude and latitude of the device. The detection unit 230 can detect the movement of the user terminal 200. For example, the detection unit 230 includes a gyroscope sensor and an accelerometer sensor, and detects angular velocity and acceleration.

[0081] Communication unit 240 is a communication interface for sending and receiving information between user terminal 200 and another device. Communication unit 240 performs communication conforming to any wired or wireless communication standard. Examples of communication standards that can be used include standards employing USB (Universal Serial Bus), Wi-Fi (trademarked), Bluetooth (trademarked), NFC (Near Field Communication), or LPWA (Low Power Wide Area).

[0082] Memory cell 250 stores various types of information. For example, memory cell 250 is configured with a non-volatile storage medium (such as flash memory).

[0083] The control unit 260 functions as an arithmetic processing device or control device, thereby controlling the overall operation within the user terminal 200 according to various programs. For example, the control unit 260 may be implemented by a CPU (Central Processing Unit) or electronic circuitry (such as a microprocessor).

The control unit 260 also controls other processing implemented by the user terminal 200, such as processing based on information input to and output from each component.

[0084] It should be noted that the functions of control unit 260 can be implemented using an application. This application can be pre-installed or downloaded. Furthermore, the functions of control unit 260 can be implemented using a PWA (Progressive Web Application).

[0085] <<3. Configuration of Heating Curve>>

[0086] Control unit 116 controls the operation of heating unit 121 based on the heating curve. The operation of heating unit 121 is controlled by controlling the power supply from power supply unit 111 to heating unit 121. Heating unit 121 uses the power supplied from power supply unit 111 to heat rod substrate 150.

[0087] A heating profile is control information used to control the temperature at which the aerosol source is heated. The heating profile specifies parameters related to the temperature at which the aerosol source is heated. The temperature of heating unit 121 is an example of the temperature at which the aerosol source is heated. A target value for the temperature of heating unit 121 (hereinafter also referred to as the "target temperature") is an example of parameters related to the temperature at which the aerosol source is heated. The temperature of heating unit 121 can be controlled to change according to the time elapsed since the start of heating. In this case, the heating profile includes information defining the time-series transition of the target temperature. As another example, the heating profile may include parameters defining how power is supplied to heating unit 121 (hereinafter also referred to as power supply parameters). Power supply parameters include, for example, the voltage applied to heating unit 121, the on / off state of power supply to heating unit 121, or the feedback control method to be employed. The on / off state of power supply to heating unit 121 can be considered as the on / off state of heating unit 121.

[0088] Control unit 116 controls the operation of heating unit 121 such that the temperature of heating unit 121 (hereinafter also referred to as "actual temperature") changes to resemble the target temperature defined in the heating profile. The heating profile is typically designed to optimize the flavor tasted by the user when the user inhales the aerosol generated from the rod matrix 150. Therefore, the flavor tasted by the user can be optimized by controlling the operation of heating unit 121 based on the heating profile.

[0089] Temperature control of heating unit 121 can be achieved, for example, through known feedback control. Feedback control can be, for example, PID control (proportional-integral-derivative controller). Control unit 116 can supply power from power supply unit 111 to heating unit 121 in pulse form using pulse width modulation (PWM) or pulse frequency modulation (PFM). In this case, control unit 116 can perform temperature control of heating unit 121 by adjusting the frequency or duty cycle of the power pulses in the feedback control. Alternatively, control unit 116 can perform simple on / off control in the feedback control. For example, control unit 116 can perform heating of heating unit 121 until the actual temperature reaches the target temperature, interrupt heating of heating unit 121 when the actual temperature reaches the target temperature, and resume heating of heating unit 121 when the actual temperature drops below the target temperature.

[0090] For example, the temperature of the heating unit 121 can be quantified by measuring or estimating the resistance value of the heating unit 121 (more precisely, the heating resistor element constituting the heating unit 121). This is because the resistance value of the heating resistor element changes with temperature. For example, the resistance value of the heating resistor element can be estimated by measuring the amount of voltage drop across the heating resistor element. The amount of voltage drop across the heating resistor element can be measured by a voltage sensor that measures the potential difference applied to the heating resistor element. In another example, the temperature of the heating unit 121 can be measured by a temperature sensor (such as a thermistor mounted near the heating unit 121).

[0091] The period from the start to the end of the process of generating aerosols using the rod-shaped matrix 150 is also referred to hereinafter as the heating phase. In other words, the heating phase is the period during which the power supply to the heating unit 121 is controlled based on a heating curve. The heating phase begins when heating based on the heating curve begins. The heating phase ends when a sufficient amount of aerosol is no longer generated. The heating phase includes a preheating period in the first half and a recommended suction period in the second half. The recommended suction 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 suction period. Heating performed during the preheating period is also referred to as preheating.

[0092] The notification unit 113 can notify the user of information indicating the end of the preheating period. For example, the notification unit 113 may notify the user of the end of the preheating period before it ends, or notify the user of the end of the preheating period. For example, the notification may be given to the user by illuminating an LED or by vibrating a vibration device. By referring to such a notification, the user can begin suction immediately after the preheating period ends.

[0093] Similarly, notification unit 113 can notify the user of information indicating when the recommended suction period ends. For example, notification unit 113 may notify the user of the end of the recommended suction period before it ends, or notify the user of the end of the recommended suction period. For example, notification to the user can be given by illuminating an LED or vibrating the vibration device. By referring to such notification, the user can continue suctioning until the recommended suction period ends.

[0094] Reference Figure 4 An example describing a heating curve. Figure 4 This is a schematic graph illustrating an example of a heating curve. The horizontal axis of the graph represents time. The vertical axis of the graph represents temperature. Figure 4As shown, the heating phase can sequentially include a first heating period, a cooling period (described as an "intermediate cooling period"), and a second heating period. The first heating period is the period during which the temperature of the heating unit 121 rises rapidly and remains at a high temperature after the start of heating. The cooling period is the period during which the temperature of the heating unit 121 decreases after the first heating period. The second heating period is the period during which the temperature of the heating unit 121 rises again after the cooling period. Figure 4 In the example shown, the target temperature rapidly rises to approximately 330°C during the first heating phase, then drops to approximately 230°C during the cooling phase, and subsequently gradually rises to approximately 300°C during the second heating phase. During the cooling phase, the power supply to the heating unit 121 can be interrupted, and heating can be cut off. Figure 4 In the example shown, the period from the start of heating to the middle of the first heating period is the preheating period, and the period from the middle of the first heating period to the end of the second heating period is the recommended suction period.

[0095] <<4. Operation Example>>

[0096] In one embodiment of this disclosure, the inhalation device 100 is configured to generate an aerosol for user evaluation. The user terminal 200 is also configured to receive evaluations from the user. Furthermore, the user terminal 200 is capable of transmitting a heating profile based on the user's evaluation results to the inhalation device 100. Additionally, the inhalation device 100 is configured to allow heating control to be performed based on the heating profile provided according to the user's evaluation results.

[0097] The following description, with reference to the accompanying drawings, illustrates a processing example of a system including an inhalation device 100 and a user terminal 200 according to an embodiment of this disclosure.

[0098] Furthermore, the action of a user inhaling the aerosol generated by the inhalation device 100 will be referred to as "inhalation" or "sucking" in the following text. In addition, the action of a user inhaling will also be referred to as "sucking action" in the following text.

[0099] When a user of the inhalation device 100 performs a series of inhalations, typically about 12 inhalations are performed. The duration of this series of inhalations is also referred to as the "inhalation phase" or "smoking phase." In the control unit 116, the heating operation of the heating units 121 (121A, 121B) for the user's series of inhalations is pre-designed as the "inhalation phase." That is, the control unit 116 operates the inhalation device 100 according to the predefined inhalation phase.

[0100] It should be noted that the "inhalation phase" or "smoking phase" can also be referred to as the "heating phase." In other words, the period from the start to the end of the treatment using the rod matrix 150 to generate an aerosol corresponds to the heating phase. In other words, the heating phase is the period during which the power supply to the heating unit 121 is controlled based on a heating curve. The heating phase begins at the moment of heating start based on the heating curve (i.e., when heating of the rod matrix 150 begins). The heating phase ends when a sufficient amount of aerosol is no longer generated. The heating phase includes a preheating period and a recommended inhalation period following the preheating period.

[0101] 4-1 Overall Processing Example

[0102] Figure 5 This is a sequence diagram illustrating a processing example of a control system including an inhalation device 100 and a user terminal 200 according to an embodiment of this disclosure. This control system is an example of the control systems in this disclosure. Figure 5 As shown, steps S101 to S105 are the preparation phase for the evaluation. During the preparation phase, the inhalation device 100 downloads a dedicated heating curve from the user terminal 200 for use in the evaluation. Next, steps S106 to S112 are the inhalation phase for the evaluation. During the inhalation phase, the inhalation device 100 uses the dedicated heating curve to perform heating control, and the user terminal 200 displays a user interface (UI) to prompt the user to perform inhalation. Finally, steps S113 to S118 are the evaluation phase. During the evaluation phase, the user terminal 200 displays an evaluation UI for the evaluation and prompts the user to perform the evaluation. Then, the inhalation device 100 downloads a heating curve from the user terminal 200 based on the user's evaluation results.

[0103] In step S101, the inhalation device 100 receives a predetermined action from the user to initiate an assessment. For example, the predetermined action is the user selecting an icon displayed on the user terminal 200 to begin the assessment. For instance, the predetermined action could be tapping the screen of the user terminal 200. It should be noted that the predetermined action can be any action from the user to begin the assessment. For example, the predetermined action could be the user pressing a predetermined button or similar action on the user terminal 200.

[0104] In step S102, after receiving a predetermined action from the user, the user terminal 200 transmits a dedicated heating profile for evaluation to the inhalation device 100. The inhalation device 100 receives the dedicated heating profile for evaluation from the user terminal 200.

[0105] The dedicated heating profile used for evaluation is a heating profile designed to induce changes in the smoking flavor of the aerosol. In one embodiment of this disclosure, a user actually uses the inhalation device 100 to evaluate the smoking flavor of the inhaled aerosol. To enable the user to evaluate the smoking flavor of the aerosol with each inhalation, it is desirable to change the smoking flavor of the aerosol with each inhalation. Therefore, the dedicated heating profile used for evaluation is... Figure 4 The heating curve shown here, compared to the heating curve used for normal heating control, makes the smoking flavor of the aerosol more susceptible to change.

[0106] For example, a dedicated heating profile is a heating profile with a higher heating rate than that used for normal heating. Since the inhalation device 100 heats the heater according to this heating profile, the high heating rate of the profile can cause the heating temperature of the aerosol source to rise rapidly. It is known that different heating temperatures of the aerosol source can also result in different smoking flavors of the aerosols produced by the aerosol source. In other words, because the dedicated heating profile has a higher heating rate than that used for normal heating, the heating temperature of the aerosol source can rise rapidly, and therefore, the smoking flavor of the resulting aerosols can also change rapidly.

[0107] Figure 6 This is a schematic diagram of an example of a dedicated heating profile used for evaluation. The horizontal axis of the graph represents time. The vertical axis of the graph represents temperature. Figure 6 As shown, for example, the dedicated heating curve used for evaluation has a higher temperature during the second heating period than... Figure 4 The heating curve shown is for a higher heating rate than normal heating. Figure 4 In the normal heating curve shown, the temperature rises from approximately 230°C to approximately 300°C during the second heating period of approximately 260 seconds. In contrast, in... Figure 6 In the dedicated heating curve shown, during the second heating period of approximately 80 seconds, the temperature rises from approximately 230°C to approximately 330°C. In other words, for example, Figure 6 The dedicated heating curve shown has a higher temperature during the second heating period than Figure 4 The heating curve shown is for normal heating with a higher rate of temperature rise.

[0108] Inhalation device 100 in use Figure 6 The dedicated heating profile shown in the diagram controls the heating process, thereby altering the smoking flavor of the aerosol generated from the aerosol source within a short period. Therefore, when using the dedicated heating profile for heating control, users are more likely to notice the change in the smoking flavor of the inhaled aerosol compared to when using a normal heating profile.

[0109] like Figure 6As shown, when heating control is performed using a dedicated heating profile, the user performs multiple suction cycles. Figure 6 In the example, seven inhalation times are set within the second heating period of the dedicated heating curve, and it is assumed that the user will perform seven inhalations. Here, the inhalation device 100 can also change the smoking flavor of the generated aerosol within a short time by performing heating control using the dedicated heating curve. Therefore, the user can notice the change in the smoking flavor of the aerosol with each inhalation and can evaluate the smoking flavor of the aerosol with each inhalation. Figure 6 In the example, users can experience the changing smoking flavor of the inhaled aerosol during each of the seven inhalations.

[0110] It should be noted that the user's suction time can be as follows: Figure 6 The intervals can be set to equal intervals as shown, or they can be set to arbitrarily defined intervals. Furthermore, there is no need to preset the user's suction time, and users can be allowed to perform suction at any time. Additionally, the number of suctions can be as follows... Figure 6 The seven times shown can also be any number of suctions.

[0111] Furthermore, dedicated heating profiles are not limited to heating profiles with a higher heating rate than those used for normal heating (e.g., Figure 6 (The heating profile shown). For example, a dedicated heating profile could be one that increases the temperature in a more gradual manner with each puff compared to a heating profile used for normal heating. It should be noted that dedicated heating profiles used for evaluation are not limited to these examples and can be any heating profile that easily causes changes in the smoking flavor of the aerosol.

[0112] In step S103, the inhalation device 100 temporarily stores a dedicated heating curve for evaluation received from the user terminal 200. The inhalation device 100 temporarily stores the dedicated heating curve in volatile memory or the like. It should be noted that the inhalation device 100 may also temporarily store the dedicated heating curve in non-volatile memory.

[0113] The dedicated heating profile used for evaluation is one that makes the smoking flavor of the aerosol more susceptible to change compared to the heating profile used for normal heating control. Therefore, the dedicated heating profile for evaluation is not intended to be reused. Thus, the inhalation device 100 can be configured to temporarily store the dedicated heating profile and use it only for heating control for evaluation purposes. Then, when the heating control for evaluation purposes is complete, the inhalation device 100 can delete the dedicated heating profile. It should be noted that the inhalation device 100 does not necessarily need to delete the dedicated heating profile and can be configured to prohibit reuse while continuing to store it. Furthermore, if necessary, the inhalation device 100 can be configured to be able to reuse the dedicated heating profile several times (e.g., approximately two or three times).

[0114] In step S104, when the inhalation device 100 has completed preparation for heating control for evaluation purposes, the inhalation device transmits a preparation completion notification to the user terminal 200. The user terminal 200 receives the preparation completion notification from the inhalation device 100.

[0115] In step S105, upon receiving a preparation completion notification from the inhalation device 100, the user terminal 200 notifies the user that the evaluation preparation is complete. For example, the output unit 220 of the user terminal 200 displays a UI indicating that the evaluation preparation is complete. For example, if the user terminal 200 includes a display as the output unit 220, the output unit 220 displays information indicating that the evaluation preparation is complete, for example, on the display. It should be noted that the user terminal 200 may use any method to notify the user that the evaluation preparation is complete.

[0116] In step S106, the inhalation device 100 receives a predetermined action from the user to initiate heating. For example, the predetermined action to initiate heating is an action performed by the user on the inhalation device 100. For example, the predetermined action to initiate heating is the user pressing a predetermined button provided on the inhalation device 100. For example, the predetermined action to initiate heating is the user pressing a predetermined button provided on the inhalation device 100 a predetermined number of times and / or for a predetermined duration. The predetermined number of times can be once or multiple times. The predetermined duration can be set to any time, such as 2 seconds.

[0117] The predetermined action for initiating heating can be any action performed by the user on the inhalation device 100. For example, the predetermined action for initiating heating could be the user shaking the inhalation device 100, the user using the inhalation device 100 to trace a predetermined path or letters, or the user tapping the inhalation device 100. It should be noted that the predetermined action for initiating heating is not limited to these actions and can be any action.

[0118] In addition, the inhalation device 100 includes sensors (such as motion sensors or accelerometers) for sensing movement of the inhalation device 100, and uses these sensors to sense a third action on the inhalation device 100. For example, the motion sensor of the inhalation device 100 senses the action of a user shaking the inhalation device 100.

[0119] Furthermore, the predetermined action to initiate heating can be that the user inserts the rod-shaped substrate 150 into the suction device 100. For example, the user inserts the rod-shaped substrate 150 into the internal space 141 of the suction device 100. The suction device 100 is able to sense that the rod-shaped substrate 150 has been inserted into the internal space 141. The insertion of the rod-shaped substrate 150 into the internal space 141 of the suction device 100 can be sensed by changes in the temperature or resistance value of the heating unit 121. Additionally, the rod-shaped substrate 150 can also be sensed by sensing changes in capacitance caused by the insertion of the rod-shaped substrate 150, or changes in magnetic field or magnetism caused by the insertion of the rod-shaped substrate 150. Furthermore, the rod-shaped substrate 150 can also be sensed by, for example, using an infrared sensor to sense its presence. The sensing of the rod-shaped substrate 150 is not limited to these examples, and any method can be used to perform this action.

[0120] In step S107, when the inhalation device 100 has received a predetermined action to start heating, heating control begins based on a temporarily stored dedicated heating curve. For example, the control unit 116 of the inhalation device 100 begins controlling the operation of the heating unit 121 based on the dedicated heating curve temporarily stored in step S103.

[0121] In step S108, the inhalation device 100 notifies the user terminal 200 of the heating status. The heating status includes the progress status of the heating process. For example, the inhalation device 100 notifies the user terminal 200 of the heating status at predetermined intervals. The inhalation device 100 may, for example, issue a notification indicating the end of each time period in the heating curve as a heating status. "Each time period in the heating curve" refers to, for example, each of a first heating period, a cooling period, and a second heating period. Furthermore, the inhalation device 100 may, for example, issue a notification indicating the start of each time period in the heating curve at the start time point as a heating status.

[0122] The suction device 100 can notify the user terminal 200 of the suction time as a notification of the heating status. For example... Figure 6 As shown, for example, the dedicated heating curve includes seven suction moments. The suction device 100 can emit... Figure 6The seven suction time notifications shown serve as notifications of the heating state. Furthermore, the suction device 100 can issue notifications of both the heating state and suction time. In this case, the heating state notification and the suction time notification are separate notifications.

[0123] In step S109, the user terminal 200 notifies the user of the suction time. For example... Figure 6 As shown, for example, the dedicated heating curve includes seven suction moments. For example, the output unit 220 of the user terminal 200 displays a UI indicating the suction moments. For example, if the user terminal 200 includes a display as the output unit 220, the output unit 220 displays information indicating the suction moments on the display, for example.

[0124] It should be noted that the user terminal 200 can notify the user of the suction time using any method. Furthermore, the inhalation device 100 can also notify the user of the suction time. In this case, at least one of the user terminal 200 and the inhalation device 100 can notify the user of the suction time. For example, the notification unit 113 of the inhalation device 100 displays a UI indicating the suction time. The notification unit 113 of the inhalation device 100 notifies the user of the suction time by, for example, emitting light from an LED in a predetermined manner. Alternatively, the notification unit 113 of the inhalation device 100 notifies the user of the suction time by, for example, vibrating a vibration device in a predetermined manner. Furthermore, if the inhalation device 100 is provided with a display as the notification unit 113, the notification unit 113 notifies the user of the suction time by, for example, displaying the suction time on the display. It should be noted that the inhalation device 100 can notify the user of the suction time using any method.

[0125] Figure 7 This is a schematic diagram illustrating an example of a user terminal's screen display. Figure 7 The screen display of the user terminal 200 shown is an example of a screen display when information indicating the timing of aspiration is displayed on the monitor.

[0126] like Figure 7 As shown, the screen display indicating the aspiration time includes information 221 indicating the number of aspirations. This information includes information indicating the current number of aspirations and information indicating the total number of aspirations. Figure 7 In the example, "the 3rd time" is included as the current number of suctions, and "7 suctions" is included as the total number of suctions.

[0127] The screen display indicating the suction time also includes a generally elliptical icon 222 representing each suction. Icon 222 moves from right to left on the screen over time. The screen display indicating the suction time also includes a vertical bar 223 indicating the "current time," which is displayed in the center of the screen. When bar 223 intersects one of the icons 222, the user knows it's time for a suction. The screen display indicating the suction time also includes text 224. For example, text 224 contains the message "Please inhale when the device vibrates." Figure 7 The term "vibration" in text 224 shown refers to vibration caused by the vibration device of the suction device 100. It should be noted that the content of text 224 can be any message prompting the user to inhale.

[0128] like Figure 7 As shown in the diagram, a screen indicating the suction timing is displayed on the user terminal 200. Therefore, the user of the inhalation device 100 can perform inhalation while referring to the screen display indicating the suction timing on the user terminal 200.

[0129] In step S110, the inhalation device 100 terminates the heating control based on a dedicated heating curve.

[0130] In step S111, when the inhalation device 100 has terminated heating control, the inhalation device transmits a termination notification to the user terminal 200 indicating that heating control has been terminated. The user terminal 200 receives the termination notification from the inhalation device 100.

[0131] In step S112, upon receiving a termination notification indicating that heating control has been terminated, the user terminal 200 notifies the user that heating has been terminated. For example, the output unit 220 of the user terminal 200 displays a UI indicating that heating control has been terminated. For example, if the user terminal 200 includes a display as the output unit 220, the output unit 220 displays information indicating that heating control has been terminated on the display, for example.

[0132] In step S113, the user terminal 200 displays an evaluation UI to the user to evaluate the smoking flavor of the inhaled aerosol. For example, if the user terminal 200 includes a display as an output unit 220, the output unit 220 displays, for example, the evaluation UI on the display for evaluating the smoking flavor of the inhaled aerosol. The user terminal 200 displays the evaluation UI, which allows selection of any one of a series of puffs performed by the user based on the smoking flavor of the aerosol. For example, the user can select from the series of puffs the puff that the user feels provides the best aerosol smoking flavor. Furthermore, for example, the user can select from the series of puffs the puff that the user feels has the best overall smoking flavor. Additionally, for example, the user can select from the series of puffs the puff that the user feels provides the maximum aerosol vapor volume. Additionally, for example, the user can select from the series of puffs the puff that the user feels has the highest aerosol temperature. In this way, the user can select any one of a series of puffs based on various evaluation metrics.

[0133] Figure 8 This is a schematic diagram showing an example of an evaluation screen on a user terminal. Figure 8 The screen display of the user terminal 200 shown in the example illustrates an evaluation UI that allows selection of any one of multiple puffs performed by the user based on the aerosol's smoking flavor.

[0134] like Figure 8 As shown, the evaluation UI for assessing the smoking flavor of the inhaled aerosol includes icons 225 corresponding to each puff. The number of icons 225 corresponds to the number of puffs performed by the user when using heating control with a dedicated heating profile. Figure 8 In the example, the number of icons 225 corresponds to the total number of sucks, which is "7". Each icon 225 can be selected by the user. For example, the user can select one of multiple icons 225 by tapping the screen of the user terminal 200. It should be noted that any method can be used to accept the user's selection of icons 225, as long as the icons 225 can be selected. Figure 8 In the example, icon 225, corresponding to the fourth suction, is selected by the user. The color of the user-selected icon 225 can be changed. For example, the color of the user-selected icon 225 can be changed to a different color than the other unselected icons. This allows the user to distinguish the selected icon 225 from the other icons. Furthermore, this configuration allows other icons to be unselectable if the user selects one icon 225. This prevents the user from accidentally selecting multiple icons.

[0135] like Figure 8As shown, the evaluation UI used to assess the smoking flavor of the inhaled aerosol may include text 226. For example, text 226 may contain the message "Select the best-tasting puff". It should be noted that the content of text 226 may be any message prompting the user to select icon 225.

[0136] like Figure 8 As shown, the user terminal 200 displays an evaluation UI for assessing the smoking flavor of the inhaled aerosol. Therefore, a user of the inhalation device 100 can select any one of multiple inhalations performed by the user based on the smoking flavor of the aerosol.

[0137] In step S114, the user terminal 200 receives the user's evaluation results. The user terminal 200 receives the user's evaluation results and identifies the puffs selected based on aerosol smoking flavor from multiple puffs performed by the user. Figure 8 In the example, user terminal 200 identifies the icon 225 selected by the user from a plurality of icons 225, and identifies the suction corresponding to the identified icon 225. Figure 8 In the example, since the user selected icon 225 corresponding to the fourth suction, the user terminal 200 identifies the fourth suction.

[0138] In step S115, the user terminal 200 transmits a predetermined heating curve corresponding to the identified suction to the inhalation device 100. The inhalation device 100 receives the predetermined heating curve from the user terminal 200.

[0139] In step S116, the inhalation device 100 stores a predetermined heating curve received from the user terminal 200. While the inhalation device 100 may temporarily store dedicated heating curves, the predetermined heating curve received from the user terminal 200 is continuously stored unless requested to be deleted or overwritten. For example, the inhalation device 100 stores the predetermined heating curve received from the user terminal 200 in non-volatile memory. Therefore, the inhalation device 100 can use the predetermined heating curve to perform heating control in new smoking phases.

[0140] In one embodiment of this disclosure, each of the multiple suctions is associated with a predetermined heating curve. For example, each of the seven suctions is associated with a different predetermined heating curve. For example, a first heating curve is associated with the first suction. A second heating curve is associated with the second suction. A third heating curve is associated with the third suction. A fourth heating curve is associated with the fourth suction. In this way, the Nth heating curve is associated with the Nth suction. The user terminal 200 transmits the predetermined heating curve associated with the user-selected suction to the suction device 100. Figure 8In the example, a fourth heating curve associated with the fourth suction selected by the user is transmitted to the suction device 100.

[0141] In one embodiment of this disclosure, the predetermined heating curve associated with each puff in a series of puffs is a heating curve capable of reproducing a smoking flavor similar to the aerosol smoking flavor of each puff in a series of puffs with a dedicated heating curve. For example, a first heating curve associated with the first puff is a heating curve capable of reproducing a smoking flavor similar to the aerosol smoking flavor of the first puff in the dedicated heating curve. Similarly, a second heating curve associated with the second puff is a heating curve capable of reproducing a smoking flavor similar to the aerosol smoking flavor of the second puff in the dedicated heating curve. Similarly, an Nth heating curve associated with the Nth puff is a heating curve capable of reproducing a smoking flavor similar to the aerosol smoking flavor of the Nth puff in the dedicated heating curve.

[0142] Here, the user selects one inhalation from multiple inhalations that they perceive as providing a pleasant-tasting aerosol. Therefore, the predetermined heating profile is one that can reproduce a smoking flavor similar to the aerosol's perceived pleasant taste. The user terminal 200 transmits the predetermined heating profile corresponding to the user-selected inhalation to the inhalation device 100. Thus, the predetermined heating profile received by the inhalation device 100 is one that can reproduce a smoking flavor similar to the aerosol's perceived pleasant taste.

[0143] It should be noted that different heating curves do not necessarily need to be associated with each of the multiple aspirations. A heating curve can be associated with at least two aspirations in a series of aspirations. For example, if heating curve A is associated with the first aspiration, then the same heating curve A can also be associated with the second aspiration. In this case, heating curve B, which is different from heating curve A, can be associated with the third aspiration. For example, in Figure 8 In the example, the same heating curve A can be associated with the first and second suctions. In this case, heating curve B can be associated with the third suction, heating curve C with the fourth suction, and heating curve D with the fifth suction. Furthermore, heating curve E can be associated with the sixth and seventh suctions. It should be noted that each of heating curves A, B, C, D, and E is a distinct heating curve. Figure 8 In the example, user terminal 200 transmits the heating curve C associated with the fourth suction selected by the user to suction device 100.

[0144] In this case, the predetermined heating profile associated with multiple puffs can be a heating profile capable of reproducing the average aerosol smoking flavor of each puff in the multiple puffs within the dedicated heating profile. Furthermore, the predetermined heating profile associated with multiple puffs can be a heating profile capable of reproducing a smoking flavor similar to the aerosol smoking flavor of any puff in the multiple puffs within the dedicated heating profile.

[0145] Figure 9 This is a graph showing an example of a predetermined heating curve. The horizontal axis of the graph represents time. The vertical axis of the graph represents temperature. Figure 9 The heating curve shown is the one maintained at a constant temperature during the second heating period. In the predetermined heating curve, the maintained constant temperature corresponds to the heating temperature during a specific suction cycle in the dedicated heating curve. (As shown in the image...) Figure 8 The fourth suction, selected by the user, is shown in the image. Figure 6 The heating temperature in the dedicated heating curve shown is, for example, 280°C. In this case, the predetermined heating curve maintains a heating temperature of 280°C during the second heating period, which is the suction heating temperature in the dedicated heating curve. Therefore, the inhalation device 100 can maintain the heating of the aerosol source at a heating temperature of 280°C, which is the suction heating temperature selected by the user. In other words, the inhalation device 100 can continuously generate aerosol at a heating temperature of 280°C during the second heating period, which is the suction heating temperature selected by the user.

[0146] It is known that the smoking flavor of the generated aerosol varies depending on the temperature at which the aerosol source is heated, and the likelihood of the generated aerosol having the same smoking flavor increases if the aerosol source is heated to the same temperature. Therefore, by configuring the inhalation device 100 to maintain the heating of the aerosol source at 280°C (which is the user-selected inhalation heating temperature) during a new smoking phase, the likelihood of the user being able to enjoy the smoking flavor of the aerosol generated at 280°C for a longer period of time can be increased.

[0147] It should be noted that the predetermined heating profile can be any heating profile capable of reproducing a smoking flavor similar to the aerosol smoking flavor selected by the user during inhalation. Furthermore, the predetermined heating profile can only reproduce a smoking flavor similar to the aerosol smoking flavor selected by the user during inhalation for a certain period of time.

[0148] In step S117, when the setting based on the predetermined heating curve is completed, the inhalation device 100 transmits a setting completion notification to the user terminal 200. The user terminal 200 receives the setting completion notification from the inhalation device 100.

[0149] In step S118, upon receiving a setup completion notification from the inhalation device 100, the user terminal 200 notifies the user that the setup is complete. For example, the output unit 220 of the user terminal 200 displays a UI indicating that the setup is complete. For example, if the user terminal 200 includes a display as the output unit 220, the output unit 220 displays information indicating that the setup is complete on the display, for example. It should be noted that the user terminal 200 may use any method to notify the user that the setup is complete.

[0150] In one embodiment of this disclosure, the inhalation device 100 downloads a dedicated heating profile for evaluation from the user terminal 200. This enables the inhalation device 100 to perform heating control based on the dedicated heating profile for evaluation. Furthermore, since the inhalation device 100 temporarily stores the dedicated heating profile, it prevents the dedicated heating profile from being reused for heating control.

[0151] In one embodiment of this disclosure, the inhalation device 100 uses a dedicated heating profile to perform heating control. This dedicated heating profile can alter the smoking flavor of the aerosol generated by the aerosol source within a short timeframe. Therefore, the user is more likely to notice changes in the smoking flavor of the inhaled aerosol, making it easier for the user to subsequently evaluate the vaping. Furthermore, the user terminal 200 notifies the user of the vaping time. Thus, the user of the inhalation device 100 can perform vaping while referring to a screen display indicating the vaping time shown on the user terminal 200.

[0152] In one embodiment of this disclosure, the user terminal 200 displays an evaluation UI for assessing the smoking flavor of the inhaled aerosol. Therefore, a user of the inhalation device 100 can select any one of multiple puffs performed by the user based on the smoking flavor of the aerosol. Furthermore, the user terminal 200 transmits a predetermined heating curve corresponding to the specified puff to the inhalation device 100. Thus, a user of the inhalation device 100 can cause new heating control to be performed using the predetermined heating curve associated with the user-selected puff. Here, the predetermined heating curve is a heating curve capable of reproducing a smoking flavor similar to the smoking flavor of the aerosol in the user-selected puff. Therefore, the user of the inhalation device 100 can enjoy a smoking flavor similar to the smoking flavor of the aerosol in the selected puff during a new smoking phase.

[0153] 4-2 Example of preparation phase processing

[0154] Figure 10 This is a sequence diagram illustrating a processing example of the preparation phase in a processing example of a control system including an inhalation device 100 and a user terminal 200 in an embodiment disclosed herein. Figure 10 The processing example in the sequence diagram shown corresponds to Figure 5The processing example shown in steps S101 to S105.

[0155] In step S201, the inhalation device 100 receives a predetermined action from the user to initiate an assessment. For example, the predetermined action is the user selecting an icon displayed on the user terminal 200 to begin the assessment. For instance, the predetermined action could be tapping the screen of the user terminal 200. It should be noted that the predetermined action can be any action from the user to accept the start of the assessment. For example, the predetermined action could be the user pressing a predetermined button or similar action provided on the user terminal 200.

[0156] In step S202, the user terminal 200 requests the number of the downloaded heating curve from the inhalation device 100. For example, the downloaded heating curve is a heating curve previously transmitted from the user terminal 200 to the inhalation device 100. The user terminal 200 requests the number of the previously transmitted heating curve from the inhalation device 100. The heating curve number is an identifier that can uniquely identify the heating curve.

[0157] In step S203, when a downloadable heating curve number is requested, the inhalation device 100 checks whether a previously downloaded heating curve exists. If a previously downloaded heating curve exists, the inhalation device 100 transmits an identifier (in other words, a number) that uniquely identifies the downloaded heating curve to the user terminal 200. On the other hand, if no previously downloaded heating curve exists, the inhalation device 100 notifies the user terminal 200 that no downloadable heating curve exists.

[0158] In step S204, the user terminal 200 requests from the inhalation device 100 the number of a heating curve to be set for heating control. The heating curve to be used for heating control is the heating curve used to perform heating control to heat the aerosol source when a predetermined action from the user to start heating is received. By setting the heating curve to be used for heating control, even if multiple heating curves are stored, the inhalation device 100 can use the set heating curve to perform heating control.

[0159] In step S205, when a request is made to set the number of the heating curve, the inhalation device 100 transmits the identifier (in other words, the number) of the heating curve to be used for heating control to the user terminal 200.

[0160] In step S206, upon receiving an identifier for a set heating curve from the inhalation device 100, the user terminal 200 notifies the user of information related to the set heating curve to be used for heating control. For example, the output unit 220 of the user terminal 200 displays a UI indicating information related to the set heating curve to be used for heating control. For example, if the user terminal 200 includes a display as the output unit 220, the output unit 220 displays, for example, the information related to the set heating curve to be used for heating control on the display. It should be noted that the user terminal 200 may use any method to notify the user of information related to the set heating curve to be used for heating control.

[0161] In step S207, the user terminal 200 receives a predetermined action from the user to actually begin the evaluation-related processing. For example, the predetermined action is the user selecting an icon displayed on the user terminal 200 to actually begin the evaluation processing. For example, the predetermined action could be tapping the screen of the user terminal 200. It should be noted that the predetermined action can be any action from the user to accept the actual start of the evaluation processing. For example, the predetermined action could be the user pressing a predetermined button or similar action set on the user terminal 200.

[0162] In step S208, the user terminal 200 requests calibration value data from the inhalation device 100. The calibration value data is data related to the characteristics of the heating unit 121 of the inhalation device 100. Each heating unit 121 of the inhalation device 100 has different characteristics. Therefore, even if the same heating curve is used to perform heating control, the heating temperature of each heating unit 121 will differ depending on its characteristics. Therefore, it is necessary to adjust the heating curve used in the inhalation device 100 based on data related to the characteristics of the heating unit 121 of the inhalation device 100 being used to achieve a suitable heating temperature. Accordingly, the user terminal 200 requests calibration value data related to the heating curve from the inhalation device 100 and adjusts the heating curve to be transmitted to the inhalation device 100 based on the data related to the characteristics of the heating unit 121 of the inhalation device 100.

[0163] In step S209, when calibration value data is requested, the inhalation device 100 transmits the calibration value data to the user terminal 200. The user terminal 200 adjusts the dedicated heating curve to be transmitted to the inhalation device 100 based on the calibration value data received from the inhalation device 100.

[0164] In step S210, the user terminal 200 transmits a dedicated heating curve to be used for evaluation to the inhalation device 100. The dedicated heating curve can be sent and received in a single transmission or in multiple separate transmissions. For example, the user terminal 200 can divide the dedicated heating curve into multiple datasets and transmit these datasets in multiple transmissions. The dedicated heating curve used for evaluation is a heating curve that induces changes in the smoking flavor of the aerosol, such as... Figure 6 The dedicated heating profile used for evaluation is shown in the image. Figure 4 The heating curve shown here, compared to the heating curve used for normal heating control, makes the smoking flavor of the aerosol more susceptible to change.

[0165] In step S211, the inhalation device 100 temporarily stores a dedicated heating curve received from the user terminal 200 for evaluation. The inhalation device 100 temporarily stores the dedicated heating curve in volatile memory or the like. It should be noted that the inhalation device 100 may also temporarily store the dedicated heating curve in non-volatile memory. Therefore, the inhalation device 100 can be configured to temporarily store the dedicated heating curve and use it only for heating control for evaluation purposes.

[0166] In step S212, the user terminal 200 requests the inhalation device 100 to change the heating curve set for heating control to a dedicated heating curve. The inhalation device 100 changes the heating curve used for heating control to a dedicated heating curve. This allows the inhalation device 100 to perform heating control using a dedicated heating curve.

[0167] In step S213, the inhalation device 100 notifies the user terminal 200 that it has completed the change of the heating curve that was set to be used for heating control to a dedicated heating curve.

[0168] In step S214, the inhalation device 100 sets an evaluation flag. The evaluation flag is a flag indicating that the inhalation device 100 is performing a process for evaluating the heating profile.

[0169] In step S215, when the inhalation device 100 has completed preparation for heating control for evaluation purposes, the inhalation device transmits a preparation completion notification to the user terminal 200. The user terminal 200 receives the preparation completion notification from the inhalation device 100.

[0170] In step S216, upon receiving a preparation completion notification from the inhalation device 100, the user terminal 200 notifies the user that the evaluation preparation is complete. For example, the output unit 220 of the user terminal 200 displays a UI indicating that the evaluation preparation is complete. For example, if the user terminal 200 includes a display as the output unit 220, the output unit 220 displays information indicating that the evaluation preparation is complete, for example, on the display. It should be noted that the user terminal 200 may use any method to notify the user that the evaluation preparation is complete.

[0171] In step S217, the inhalation device 100 notifies the user that preparation for the evaluation is complete. For example, the notification unit 113 of the inhalation device 100 displays a UI indicating that preparation for the evaluation is complete. The notification unit 113 of the inhalation device 100 notifies the user that preparation for the evaluation is complete, for example, by causing an LED to emit light in a predetermined manner. Alternatively, the notification unit 113 of the inhalation device 100 notifies the user that preparation for the evaluation is complete, for example, by causing a vibration device to vibrate in a predetermined manner. Furthermore, if the inhalation device 100 is provided with a display as the notification unit 113, the notification unit 113 notifies the user that preparation for the evaluation is complete, for example, by displaying information indicating that preparation for the evaluation is complete on the display. It should be noted that the inhalation device 100 may use any method to notify the user that preparation for the evaluation is complete.

[0172] In one embodiment of this disclosure, the inhalation device 100 downloads a dedicated heating profile for evaluation from the user terminal 200. This enables the inhalation device 100 to perform heating control based on the dedicated heating profile for evaluation. Furthermore, since the inhalation device 100 temporarily stores the dedicated heating profile, it prevents the dedicated heating profile from being reused for heating control.

[0173] 4-3 Example of treatment during the smoking stage

[0174] Figure 11 This is a sequence diagram illustrating a processing example of the inhalation phase in a processing example of a control system including an inhalation device 100 and a user terminal 200 in an embodiment disclosed herein. Figure 11 The processing example in the sequence diagram shown corresponds to Figure 5 The processing example shown in steps S106 to S112.

[0175] In step S301, the inhalation device 100 receives a predetermined action from the user to initiate heating. For example, the predetermined action to initiate heating is an action performed by the user on the inhalation device 100. Alternatively, the predetermined action to initiate heating may be the user inserting the rod-shaped matrix 150 into the inhalation device 100.

[0176] In step S302, when the inhalation device 100 has received a predetermined action to start heating, heating control begins based on a temporarily stored dedicated heating curve. For example, the control unit 116 of the inhalation device 100 begins to control the operation of the heating unit 121 based on the temporarily stored dedicated heating curve.

[0177] In step S303, the inhalation device 100 notifies the user terminal 200 that the heating state is a preheating state. The preheating period is the period from the start of heating until the start of the recommended inhalation period. Heating performed during the preheating period is also referred to as preheating.

[0178] In step S304, upon receiving a notification from the inhalation device 100 that the status is in a preheating state, the user terminal 200 notifies the user that the status is in a preheating state. For example, the output unit 220 of the user terminal 200 displays a UI indicating that the status is in a preheating state. For example, if the user terminal 200 includes a display as the output unit 220, then the output unit 220 displays information indicating that the status is in a preheating state on the display, for example. It should be noted that the user terminal 200 may use any method to notify the user that the status is in a preheating state.

[0179] In step S305, the inhalation device 100 terminates the heating control used for preheating. The inhalation device 100 terminates the heating control used for preheating and transitions to the recommended inhalation period.

[0180] In step S306, the inhalation device 100 notifies the user terminal 200 of the heating status after preheating. The heating status includes the progress status of the heating control. For example, the inhalation device 100 notifies the user terminal 200 of the heating status after preheating at predetermined intervals. The inhalation device 100 may, for example, issue a notification indicating the end of each time period in the heating curve as a heating status. "Each time period in the heating curve" refers to, for example, each of a first heating period, a cooling period, and a second heating period. Furthermore, the inhalation device 100 may, for example, issue a notification indicating the start of each time period in the heating curve at the start time point as a heating status.

[0181] In step S307, upon receiving a heating status notification from the inhalation device 100, the user terminal 200 notifies the user of a prompt to begin inhalation. For example, the output unit 220 of the user terminal 200 displays an inhalation start UI prompting the user to begin inhalation. For example, if the user terminal 200 includes a display as the output unit 220, the output unit 220 displays the inhalation start UI prompting the user to begin inhalation on the display, for example. It should be noted that the user terminal 200 may use any method to notify the user of the inhalation start UI prompting the user to begin inhalation.

[0182] In step S308, the user terminal 200 requests notification of the suction time from the inhalation device 100.

[0183] In steps S309, S311, and S313, the inhalation device 100 notifies the user that it is time to inhale based on a dedicated heating curve. Figure 6 As shown, for example, the dedicated heating curve includes seven suction moments. Each time a suction moment arrives, the suction device 100 notifies the user that the suction moment has arrived. For example, each time a suction moment arrives, the notification unit 113 of the suction device 100 displays a UI indicating that the suction moment has arrived. The notification unit 113 of the suction device 100 notifies the user that the suction moment has arrived, for example, by causing an LED to emit light in a predetermined manner. Furthermore, the notification unit 113 of the suction device 100 notifies the user that the suction moment has arrived, for example, by causing a vibration device to vibrate in a predetermined manner. Additionally, if the suction device 100 is provided with a display as the notification unit 113, the notification unit 113 notifies the user that the suction moment has arrived, for example, by displaying information indicating that the suction moment has arrived on the display. It should be noted that the suction device 100 may use any method to notify the user that the suction moment has arrived.

[0184] In steps S310, S312, and S314, the user terminal 200 notifies the user of the suction time. For example... Figure 6 As shown, for example, the dedicated heating curve includes seven suction moments. Each time a suction moment arrives, the user terminal 200 notifies the user that the suction moment has arrived. For example, the output unit 220 of the user terminal 200 displays a UI indicating the suction moment, such as... Figure 7 As shown in the example. For instance, if the user terminal 200 includes a display as an output unit 220, then the output unit 220 displays, for example, information indicating the suction time on the display, such as... Figure 7 As shown in the image.

[0185] In step S315, the inhalation device 100 terminates the heating control based on a dedicated heating curve.

[0186] In step S316, when the inhalation device 100 has terminated heating control, the inhalation device transmits a termination notification indicating that heating control has been terminated to the user terminal 200. The user terminal 200 receives the termination notification from the inhalation device 100.

[0187] In one embodiment of this disclosure, the inhalation device 100 uses a dedicated heating profile to perform heating control. This dedicated heating profile can alter the smoking flavor of the aerosol generated by the aerosol source within a short timeframe. Therefore, the user is more likely to notice changes in the smoking flavor of the inhaled aerosol, making it easier for the user to subsequently evaluate the vaping. Furthermore, the inhalation device 100 and the user terminal 200 notify the user of the vaping time. Thus, the user of the inhalation device 100 can perform vaping while simultaneously viewing the vaping time notification on the inhalation device 100 and referring to the screen display indicating the vaping time on the user terminal 200.

[0188] 4-4 Example of processing during the evaluation phase

[0189] Figure 12 The following is a sequence diagram illustrating a processing example of the evaluation phase in a processing example of a control system including an inhalation device 100 and a user terminal 200 in an embodiment disclosed herein. Figure 12 The processing example in the sequence diagram shown corresponds to Figure 5 The processing example shown in steps S113 to S118.

[0190] In step S401, the user terminal 200 displays an evaluation UI to the user to evaluate the smoking flavor of the inhaled aerosol. For example, if the user terminal 200 includes a display as an output unit 220, the output unit 220 displays, for example, the evaluation UI for evaluating the smoking flavor of the inhaled aerosol on the display. The user terminal 200 displays the evaluation UI (in other words, a selection screen) which allows selection of any one of multiple inhalations performed by the user, such as... Figure 8 As shown in the example, users can select from multiple puffs the aerosol smoking flavor that they feel provides the best taste.

[0191] In step S402, user terminal 200 receives the user's evaluation result. User terminal 200 receives the user's evaluation result and identifies the puff selected based on aerosol smoking flavor from multiple puffs performed by the user. For example, the user evaluation involves selecting a preferred puff from multiple puffs performed by the user. For example, the user's evaluation result is the selected preferred puff. Figure 8 In the example, user terminal 200 identifies the icon 225 selected by the user from a plurality of icons 225, and identifies the suction corresponding to the identified icon 225. Figure 8 In the example, since the user selected icon 225 corresponding to the fourth suction, the user terminal 200 identifies the fourth suction.

[0192] In step S403, the user terminal 200 receives a predetermined action from the user to begin downloading a predetermined heating curve. For example, the predetermined action to begin downloading the predetermined heating curve is the user selecting an icon displayed on the user terminal 200 for starting the download. For example, the predetermined action could be tapping the screen of the user terminal 200. It should be noted that the predetermined action can be any action to begin downloading the predetermined heating curve. For example, the predetermined action could be the user pressing a predetermined button or similar action on the user terminal 200.

[0193] In step S404, the user terminal 200 notifies the server 300 of information related to the selected aspiration. For example, if the user selects the fourth aspiration, the user terminal 200 notifies the server 300 of information related to that aspiration, allowing the aspiration to be identified as the fourth aspiration. It should be noted that the notification of information related to the selected aspiration may include a request for a predetermined heating curve.

[0194] In step S405, server 300 identifies a predetermined heating curve corresponding to information related to the selected suction. Server 300 is an external device that stores predetermined heating curves associated with each suction in a series of suctions. Upon receiving information related to the selected suction from user terminal 200, server 300 can identify the predetermined heating curve associated with the selected suction. For example, server 300 receives suction-related information from user terminal 200 that allows the suction to be identified as the fourth suction, and can identify a fourth heating curve associated with the fourth suction. It should be noted that different predetermined heating curves can be associated with each suction in a series of suctions, or a predetermined heating curve can be associated with at least two suctions.

[0195] In step S406, server 300 transmits a predetermined heating curve identified based on information related to the user's selected suction to user terminal 200. The predetermined heating curve can be sent and received in a single transmission or in multiple separate transmissions. For example, server 300 can divide the predetermined heating curve into multiple datasets and transmit these datasets in multiple transmissions.

[0196] For example, server 300 transmits the predetermined heating curve identified in step S403 to user terminal 200. The predetermined heating curve transmitted by server 300 to user terminal 200 is a heating curve associated with the user's selected inhale. For example, the predetermined heating curve is a heating curve capable of reproducing a smoking flavor similar to the smoking flavor of the aerosol in the user's selected inhale. Therefore, for example, server 300 can transmit to user terminal 200 a heating curve capable of reproducing a smoking flavor similar to the smoking flavor of the aerosol in the user's selected inhale.

[0197] In step S407, the user terminal 200 requests calibration value data from the inhalation device 100. The calibration value data is data related to the characteristics of the heating unit 121 of the inhalation device 100. Each heating unit 121 of the inhalation device 100 has different characteristics. Therefore, even if the same heating curve is used to perform heating control, the heating temperature of each heating unit 121 will differ depending on its characteristics. Therefore, it is necessary to adjust the heating curve used in the inhalation device 100 based on data related to the characteristics of the heating unit 121 of the inhalation device 100 being used to achieve a suitable heating temperature. Accordingly, the user terminal 200 requests calibration value data related to the heating curve from the inhalation device 100 and adjusts the heating curve to be transmitted to the inhalation device 100 based on the data related to the characteristics of the heating unit 121 of the inhalation device 100.

[0198] In step S408, when a calibration value data is requested, the inhalation device 100 transmits the calibration value data to the user terminal 200.

[0199] In step S409, the user terminal 200 adjusts the predetermined heating curve to be transmitted to the inhalation device 100 based on the correction value data received from the inhalation device 100.

[0200] In step S410, the user terminal 200 transmits a predetermined heating curve to the inhalation device 100. The predetermined heating curve can be sent and received in a single transmission or in multiple separate transmissions. For example, the user terminal 200 can divide the predetermined heating curve into multiple datasets and transmit these multiple datasets in multiple transmissions.

[0201] In step S411, the inhalation device 100 stores a predetermined heating curve received from the user terminal 200. While the inhalation device 100 may temporarily store dedicated heating curves, the predetermined heating curve received from the user terminal 200 is continuously stored unless requested to be deleted or overwritten. For example, the inhalation device 100 stores the predetermined heating curve received from the user terminal 200 in non-volatile memory. Therefore, the inhalation device 100 can use the predetermined heating curve to perform heating control in new smoking phases.

[0202] In step S412, when the reception of the predetermined heating curve is completed, the inhalation device 100 transmits a completion notification to the user terminal 200 to indicate that the predetermined heating curve has been received. The user terminal 200 receives the completion notification from the inhalation device 100 indicating that the predetermined heating curve has been received.

[0203] In step S413, the user terminal 200 requests the inhalation device 100 to change the heating curve set for heating control to a predetermined heating curve. The inhalation device 100 then changes the heating curve used for heating control to the predetermined heating curve. This allows the inhalation device 100 to perform heating control using the predetermined heating curve.

[0204] In step S414, the inhalation device 100 transmits a completion notification to the user terminal 200 to indicate that the heating curve setting has been changed. For example, the inhalation device 100 notifies the user terminal 200 that it has completed changing the heating curve that was set to be used for heating control to a predetermined heating curve.

[0205] In step S415, the inhalation device 100 clears the evaluation flag. The evaluation flag is a flag indicating that the inhalation device 100 is performing a process for evaluating the heating profile.

[0206] In step S416, if the evaluation flag has been cleared, the inhalation device 100 notifies the user that the evaluation-related processing has been completed. For example, the notification unit 113 of the inhalation device 100 displays a UI indicating that the evaluation-related processing has been completed. The notification unit 113 of the inhalation device 100 notifies the user that the evaluation-related processing has been completed, for example, by causing an LED to emit light in a predetermined manner. Furthermore, the notification unit 113 of the inhalation device 100 notifies the user that the evaluation-related processing has been completed, for example, by causing a vibration device to vibrate in a predetermined manner. Additionally, if the inhalation device 100 is provided with a display as the notification unit 113, the notification unit 113 notifies the user that the evaluation-related processing has been completed, for example, by displaying information indicating that the evaluation-related processing has been completed on the display. It should be noted that the inhalation device 100 may use any method to notify the user that the evaluation-related processing has been completed.

[0207] In step S417, upon receiving a completion notification indicating that the heating curve settings have been changed, the user terminal 200 notifies the user that the evaluation-related processing has been completed. For example, the output unit 220 of the user terminal 200 displays a UI indicating that the evaluation-related processing has been completed. For example, if the user terminal 200 includes a display as the output unit 220, the output unit 220 displays information indicating that the evaluation-related processing has been completed on the display, for example. It should be noted that the user terminal 200 may use any method to notify the user that the evaluation-related processing has been completed.

[0208] In one embodiment of this disclosure, the user terminal 200 displays an evaluation UI for assessing the smoking flavor of the inhaled aerosol. Therefore, a user of the inhalation device 100 can select any one of multiple puffs performed by the user based on the smoking flavor of the aerosol. Furthermore, the user terminal 200 receives a predetermined heating curve corresponding to the specified puff from the server 300 and subsequently transmits the predetermined heating curve to the inhalation device 100. Therefore, a user of the inhalation device 100 can cause a new heating control to be performed using the predetermined heating curve associated with the user-selected puff. Here, the predetermined heating curve is a heating curve capable of reproducing a smoking flavor similar to the smoking flavor of the aerosol in the user-selected puff. Therefore, the user of the inhalation device 100 can enjoy a smoking flavor similar to the smoking flavor of the aerosol in the selected puff during a new smoking phase.

[0209] The foregoing description with reference to the accompanying drawings illustrates embodiments of the inhalation device, control method, and control system according to this disclosure; however, it is understood that this disclosure is not limited to such embodiments. It will be apparent to those skilled in the art that several variations or modifications within the scope of the claims will conceive, and any such variations or modifications are naturally understood to fall within the technical scope of this disclosure.

[0210] For example, the specific numerical values ​​described in the embodiments discussed above are merely examples and are not limiting.

[0211] Furthermore, the control method described in the above embodiments can be implemented by executing a pre-prepared program on a computer (processor). The program is stored on a computer-readable storage medium and is executed by reading it from the storage medium. The program can also be provided in the form of being stored in a non-transitory storage medium (such as flash memory) or can be provided via a network (such as the Internet). Furthermore, the computer executing the program can be included, for example, in the inhalation device 100 (e.g., the CPU of the inhalation device 100), but this is not limiting, and the computer can also be included in another device (e.g., a smartphone or server) capable of communicating with the inhalation device 100.

[0212] This specification and the like describe at least the following features. Components corresponding to the above embodiments are shown in parentheses by way of example, but there are no limitations on such components.

[0213] [Feature 1]

[0214] An inhalation device (inhalation device 100, 100A, 100B) includes a heating unit (heating unit 121, 121A, 121B) that generates an aerosol by heating a matrix (cartridge 120, stick matrix 150) containing an aerosol source.

[0215] Control units (control units 116, 116A, 116B) control the operation of the heating unit based on a first heating curve, which indicates the change of target temperature or target resistance value over time when the heating unit heats the substrate.
