[0065] <1. Implementation Method>

[0066] <1.1. System Configuration>

[0067] First, refer to Figure 1 to Figure 3 , an overview of an aerosol generating system according to an embodiment of the present disclosure is described.

[0068] Figure 1 1 is a diagram showing an example of the appearance structure of an aerosol generating system according to an embodiment of the present disclosure. Figure 1 As shown, the aerosol generating system 1 of the present embodiment includes an inhalation device 100 and a charging device 900. The inhalation device 100 is a device that generates a substance inhaled by a user. In the following, it is assumed that the substance generated by the inhalation device is an aerosol. In addition, the substance generated by the inhalation device may also be a gas. The charging device 900 is a device that supplies power to other devices. As an example, the charging device 900 supplies power to the inhalation device 100 to charge the inhalation device 100.

[0069] Figure 2 1 is a diagram showing an example of a state in which a rod-shaped substrate 150 is inserted into the suction device 100 of the present embodiment. Figure 2 As shown, the rod-shaped substrate 150 can be inserted into the suction device 100 from the opening 142 provided on the top surface 100a of the suction device 100. The rod-shaped substrate 150 is an example of a substrate containing an aerosol source. The suction device 100 generates an aerosol by heating the aerosol source contained in the rod-shaped substrate 150. The combination of the suction device 100, the charging device 900, and the rod-shaped substrate 150 can also be regarded as an aerosol generating system 1.

[0070] Figure 3 1 is a diagram showing an example of a state in which the connection between the suction device 100 and the charging device 900 of the present embodiment is released. Figure 3As shown, the suction device 100 and the charging device 900 can be configured to be detachable. The rod-shaped substrate 150 can also be heated to generate aerosol when the suction device 100 and the charging device 900 are connected. In addition, the rod-shaped substrate 150 can also be heated to generate aerosol when the suction device 100 and the charging device 900 are disconnected.

[0071] like Figure 1 to Figure 3 As shown, the longitudinal direction of the suction device 100 is also referred to as the up-down direction. The down direction corresponds to the insertion direction of the rod-shaped substrate 150. The up direction corresponds to the removal direction of the rod-shaped substrate 150. In the frame of the aerosol generating system 1, the surface in the up direction is also referred to as the top surface, the surface in the down direction is also referred to as the bottom surface, and the surface in the direction orthogonal to the up-down direction is also referred to as the side surface. Figure 1 to Figure 3 As shown, the suction device 100 includes a cover 20 and a main body 30. The main body 30 is an example of a first component having various components of the suction device 100 such as a heating unit 121 and a control unit 116 described later. The cover 20 is an example of a second component connected to the main body 30 in a detachable manner. The cover 20 may be an accessory that is configured as a part of a housing of the suction device 100 that can be disassembled. For example, the cover 20 is mounted on the main body 30 in a manner that covers the upper end of the main body 30. For example, the user may also have a plurality of covers 20 of different colors. The user can adjust the aesthetics of the suction device 100 by replacing the cover 20 according to his mood. Of course, the cover 20 and the main body 30 may also be configured as one piece.

[0072] like Figure 3 As shown, the suction device 100 is configured as a cylinder with a top surface 100a and a bottom surface 100b as two ends. In addition, a button 11 is provided on a side surface 100c of the suction device 100. The button 11 is an example of an operation unit that can accept user operations on the aerosol generating system 1. As an example, the suction device 100 can also start heating the rod-shaped substrate 150 when the button 11 is pressed.

[0073] like Figure 3 As shown, an LED (light-emitting diode) 12 is provided on the side 100c of the suction device 100. The LED 12 is configured to correspond to the button 11. Specifically, the LED 12 is configured to surround the button 11. The LED 12 is an example of a notification unit that outputs information notified from the aerosol generating system 1 to the user. The LED 12 can also notify information related to the process executed when the button 11 is pressed as a trigger. As an example, the LED 12 can also output information indicating the progress of the heating of the rod-shaped substrate 150 by the suction device 100. According to this configuration, the relationship between the user operation and the notification can be more easily understood.

[0074] like Figure 3As shown, a button 91 is provided on the top surface 900a of the charging device 900. The button 91 is an example of an operation unit capable of accepting user operations on the aerosol generating system 1. As an example, the charging device 900 may start / stop charging the suction device 100 when the button 91 is pressed.

[0075] like Figure 3 As shown, LED 92 is provided on the top surface 900a of the charging device 900. LED 92 is configured to correspond to button 91. Specifically, LED 92 is configured to surround button 91. LED 92 is an example of a notification unit that outputs information notified from the aerosol generating system 1 to the user. LED 92 can also notify information related to the process executed when button 91 is pressed as a trigger. As an example, LED 92 can also output information indicating the progress of charging of the suction device 100. According to this configuration, the relationship between the user operation and the notification can be more easily understood.

[0076] like Figure 3 As shown, a concave surface 900c is provided on the side of the charging device 900. The concave surface 900c is in a shape along the side surface 100c of the suction device 100. Moreover, in a state where the concave surface 900c is in contact with the side surface 100c of the suction device 100, the suction device 100 is connected to the charging device 900. A magnetic portion 13-1 and a magnetic portion 13-2 are provided on the side surface 100c of the suction device 100. On the other hand, a magnetic portion 93-1 and a magnetic portion 93-2 are provided on the concave surface 900c of the charging device 900. The magnetic portion 13-1, the magnetic portion 13-2, the magnetic portion 93-1 and the magnetic portion 93-2 are objects that generate a magnetic field, such as a magnet. When the suction device 100 and the charging device 900 are brought close to each other, the magnetic portion 13-1 and the magnetic portion 93-1 attract each other, and the magnetic portion 13-2 and the magnetic portion 93-2 attract each other, and the suction device 100 is connected to the charging device 900. As an example, one of the magnetic part 13-1 and the magnetic part 93-1 may be a magnet with an S pole, and the other may be a magnet with an N pole. Similarly, one of the magnetic part 13-2 and the magnetic part 93-2 may be a magnet with an S pole, and the other may be a magnet with an N pole. According to this structure, the suction device 100 and the charging device 900 can be easily connected and detached.

[0077] like Figure 3As shown, an electric contact 14 is provided between the magnetic part 13-1 and the magnetic part 13-2 on the side surface 100c of the suction device 100. The electric contact 14 is a contact to the circuit in the suction device 100. On the other hand, an electric contact 94 is provided between the magnetic part 93-1 and the magnetic part 93-2 on the concave surface 900c of the charging device 900. The electric contact 94 is a contact to the circuit in the charging device 900. When the suction device 100 and the charging device 900 are connected, the electric contact 14 contacts the electric contact 94. And the charging device 900 supplies power to the suction device 100 via the electric contact 14 and the electric contact 94. Thus, the suction device 100 can be charged. Regarding the connection between the suction device 100 and the charging device 900, in addition to the physical connection, the electrical connection is also included. The charging from the charging device 900 to the suction device 100 can also be started / stopped by the connection / disconnection of the suction device 100 and the charging device 900 as a trigger. The physical connection / disconnection between the suction device 100 and the charging device 900 can be detected by a magnetic sensor that can detect the magnetic field generated by the magnetic portion 93 and / or the magnetic portion 13. As an example of the magnetic sensor, a Hall sensor can be cited. The electrical connection / disconnection between the suction device 100 and the charging device 900 can be detected by whether electricity can be supplied through the electrical contacts 14 and 94.

[0078] Typically, the user removes the suction device 100 from the charging device 900 to use. In addition, unless otherwise specified, the user uses the suction device 100 to heat the rod-shaped substrate 150 by the suction device 100 to suck the aerosol. On the other hand, the user can also use the suction device 100 in a state where the suction device 100 is connected to the charging device 900. In this case, the suction device 100 can be used without worrying about the remaining battery level of the suction device 100.

[0079] like Figure 3 As shown, the button 11 is arranged in the same row as the magnetic part 13-1, the magnetic part 13-2 and the electric contact 14. According to this structure, when the suction device 100 is connected to the charging device 900, the button 11 is shielded by the concave surface 900c of the charging device 900. Thus, the button 11 can be prevented from being erroneously operated.

[0080] Likewise, if Figure 3 As shown, LED 12 is arranged in the same row as magnetic portion 13-1, magnetic portion 13-2 and electric contact 14. According to this configuration, when suction device 100 is connected to charging device 900, LED 12 is shielded by concave surface 900c of charging device 900. Thus, the notification source of information can be integrated into LED 92.

[0081] The suction device 100 and the charging device 900 can also send and receive information via the electrical contacts 14 and the electrical contacts 94. As the information sent from the suction device 100 to the charging device 900, the suction information and biological information obtained by the suction device 100 can be cited. On the other hand, as the information sent from the charging device 900 to the suction device 100, the control information that instructs the suction device 100 to perform a prescribed process can be cited. The suction information refers to the information obtained when the user uses the suction device 100 to heat the aerosol, for example, the number of puffs, the number of rod-shaped substrates 150 after heating, and the heating frequency of the rod-shaped substrate 150 can be cited. As biological information, the user's blood pressure, pulse, and body temperature can be cited. The charging device 900 can output the information obtained from the suction device 100 via an output device built into the charging device 900 such as LED 92 or a display not shown in the figure, or send it to other devices such as a smart phone. Of course, the suction device 100 can also output this information via an output device built into the suction device 100 such as LED 12 or a display not shown in the figure.

[0082] Typically, the suction device 100 operates based on a user operation on the suction device 100. For example, the suction device 100 starts / stops heating the rod-shaped substrate 150 based on the pressing of the button 11. In addition, the suction device 100 may also operate based on a user operation on the charging device 900. For example, the suction device 100 may also start / stop heating the rod-shaped substrate 150 based on the pressing of the button 91 in a state connected to the charging device 900. Considering that the button 11 is hidden and difficult to press in a state where the suction device 100 is connected to the charging device 900, this configuration can improve usability.

[0083] The above is a description of the outline of the aerosol generating system 1. The configuration of the aerosol generating system 1 is not limited to the example described above. Various modifications described below can be applied.

[0084] As an example, the suction device 100 and the charging device 900 may be configured to be inseparable. That is, the suction device 100 and the charging device 900 may be configured integrally.

[0085] As another example, the number of magnetic portions 13 provided in the suction device 100 is not limited to two, and may be one, or may be three or more. Similarly, the number of electrical contacts 14 provided in the suction device 100 is not limited to one, and may be two or more. In addition, the position of the magnetic portion 13 provided in the suction device 100 is not limited to the side surface 100c of the suction device 100, and may be the bottom surface 100b of the suction device 100. Similarly, the position of the electrical contacts 14 provided in the suction device 100 is not limited to the suction device 100, and may be the bottom surface 100b of the suction device 100. In the charging device 900, it is sufficient to provide the magnetic portions 93 and the electrical contacts 94 in the number and position corresponding to the number and position of the magnetic portions 13 and the electrical contacts 14 provided in the suction device 100.

[0086] As another example, the electric contact 14 may also function as the magnetic portion 13. Similarly, the electric contact 94 may function as the magnetic portion 93.

[0087] As another example, the charging device 900 may store the entire suction device 100. For example, a cylindrical space for storing the suction device 100 may be provided inside the charging device 900, and the suction device 100 may be accommodated in the space. The space capable of accommodating the suction device 100 may be opened and closed by a cover provided at any position of the outer shell of the charging device 900.

[0088] As another example, the charging device 900 may also wirelessly charge the suction device 100. In this case, the electrical contacts 14 and 94 may be omitted.

[0097] The control unit 116 functions as a calculation processing device and a control device, and controls the overall operation in the suction device 100 according to various programs. The control unit 116 is implemented by an electronic circuit such as a CPU (Central Processing Unit) or a microprocessor, for example.

[0098] The storage part 140 has an internal space 141, and holds the rod-shaped substrate 150 while accommodating a part of the rod-shaped substrate 150 in the internal space 141. The storage part 140 has an opening 142 that connects the internal space 141 with the outside, and accommodates the rod-shaped substrate 150 inserted into the internal space 141 from the opening 142. For example, the storage part 140 is a cylindrical body with the opening 142 and the bottom 143 as the bottom surface, and defines a columnar internal space 141. The storage part 140 is connected to an air flow path that supplies air to the internal space 141. An air inlet hole that is an inlet of air to the air flow path is, for example, arranged on the side of the suction device 100. An air outlet hole that is an outlet of air from the air flow path to the internal space 141 is, for example, arranged on the bottom 143.

[0099] The rod-shaped substrate 150 includes a substrate portion 151 and a mouthpiece 152. The substrate portion 151 includes an aerosol source. The aerosol source includes a flavor component of tobacco or non-tobacco origin. In the case where the suction device 100 is a medical inhaler such as a nebulizer, the aerosol source may also include a medicament. The aerosol source may be, for example, a polyol such as glycerin and propylene glycol containing a flavor component of tobacco or non-tobacco origin, and a liquid such as water, or a solid containing a flavor component of tobacco or non-tobacco origin. When the rod-shaped substrate 150 is held in the housing portion 140, at least a portion of the substrate portion 151 is accommodated in the internal space 141, and at least a portion of the mouthpiece 152 protrudes from the opening 142. Then, when the user holds and inhales the mouthpiece 152 protruding from the opening 142, air flows into the internal space 141 via an air flow path not shown, and reaches the user's mouth together with the aerosol generated from the substrate portion 151.

[0100] The heating unit 121 generates aerosol by heating the aerosol source to atomize the aerosol source. Figure 4 In the example shown, the heating unit 121 is configured in a film shape and is arranged so as to cover the outer periphery of the storage unit 140. Then, when the heating unit 121 generates heat, the base material portion 151 of the rod-shaped base material 150 is heated from the outer periphery, and an aerosol is generated. The heating unit 121 generates heat when power is supplied from the power supply unit 111. As an example, power may be supplied when the sensor unit 112 detects that the user has started suction and / or inputs prescribed information. Then, power supply may be stopped when the sensor unit 112 detects that the user has finished suction and / or inputs prescribed information.

[0101] The heat insulating part 144 prevents heat transfer from the heating part 121 to other components. For example, the heat insulating part 144 is made of a vacuum heat insulating material or an aerogel heat insulating material.

[0102] The above is a description of a configuration example of the suction device 100. Of course, the configuration of the suction device 100 is not limited to the above, and various configurations as exemplified below can be adopted.

[0103] As an example, the heating unit 121 may be configured in a plate shape and arranged so as to protrude from the bottom 143 of the receiving unit 140 to the internal space 141. In this case, the plate-shaped heating unit 121 is inserted into the base material portion 151 of the rod-shaped base material 150, and heats the base material portion 151 of the rod-shaped base material 150 from the inside. As another example, the heating unit 121 may be arranged so as to cover the bottom 143 of the receiving unit 140. In addition, the heating unit 121 may be configured as a combination of two or more of a first heating unit covering the outer periphery of the receiving unit 140, a plate-shaped second heating unit, and a third heating unit covering the bottom 143 of the receiving unit 140.

[0104] As another example, the housing 140 may include an opening and closing mechanism such as a hinge that opens and closes a portion of the outer shell that forms the internal space 141. Furthermore, the housing 140 may clamp and accommodate the rod-shaped substrate 150 inserted into the internal space 141 by opening and closing the outer shell. In this case, the heating unit 121 may be provided at the clamping portion of the housing 140 to heat the rod-shaped substrate 150 while pressing it.

[0105] In addition, the means for atomizing the aerosol source is not limited to the heating by the heating unit 121. For example, the means for atomizing the aerosol source may also be induction heating. In this case, the suction device 100 has at least an electromagnetic induction source such as a coil that generates a magnetic field instead of the heating unit 121. The heat-sensitive body that generates heat by induction heating may be provided in the suction device 100, or may be included in the rod-shaped substrate 150.

Similarly, the processing described as being controlled by the control unit 916 may be controlled by the control unit 116.

[0120] <1.3. Air Flow>

[0121] Below, refer to Figure 6 to Figure 8 , describing the air flow generated by suction in the suction device 100 of the present embodiment.

[0122] Figure 6 1 is a diagram for explaining an example of air flow generated by suction in the suction device 100 of the present embodiment. Figure 6, an example of a cross section of the suction device 100 and the rod-shaped substrate 150 inserted into the suction device 100 cut along the vertical direction in a manner passing through the center of the receiving portion 140 is schematically shown. Figure 6 As shown, when the rod-shaped substrate 150 is accommodated in the accommodating portion 140, there is a gap between the bottom 143 and the inner wall 145 of the accommodating portion 140 and the rod-shaped substrate 150. When the user holds the rod-shaped substrate 150 to inhale, the air flowing in from the opening 142 flows into the inside of the rod-shaped substrate 150 from the front end of the substrate portion 151 through the gap, and flows out from the rear end of the mouthpiece 152 to the user's mouth. That is, the air inhaled by the user flows in the order of air flow 190-1, air flow 190-2, and air flow 190-3, and is guided into the user's oral cavity in a state of being mixed with the aerosol generated from the rod-shaped substrate 150. According to the air flow 190-1, air flow 190-2, and air flow 190-3, the air flows from the opening 142 into the internal space 141, and the air flows out from the opening 142. In this way, the air intake and exhaust method in which the air intake path and the exhaust path are the same is also called counterflow.

[0123] Figure 7 1 is a diagram showing an example of the structure of the bottom 143 of the storage unit 140 according to the present embodiment. Figure 7 , an example of a cross section of the receiving portion 140 cut along the vertical direction with respect to the suction device 100 and the rod-shaped substrate 150 inserted into the suction device 100 is schematically shown. Figure 7 As shown in FIG. 1 , a convex portion 143a that protrudes toward the inner space 141 may be provided at the bottom 143 of the receiving portion 140. The portion other than the convex portion 143a in the bottom 143 is also referred to as a concave portion 143b. The convex portion 143a has, for example, a truncated cone shape with a flat top surface. The top surface of the convex portion 143a is configured to be at least smaller than the end surface of the rod-shaped substrate 150. Thus, as shown in FIG. Figure 7 As shown, the convex portion 143a can support the rod-shaped substrate 150 in a state where at least a part of the end surface of the rod-shaped substrate 150 is separated from the concave portion 143b. As a result, a gap through which the air flow 190-2 passes can be formed between the end surface of the rod-shaped substrate 150 and the concave portion 143b. In addition, the air flow 190-2 and the air flow 190-3 can be connected without any obstruction.

[0124] Figure 8 FIG. 1 is a diagram showing an example of the structure of the inner wall 145 of the storage unit 140 according to the present embodiment. Figure 8 , an example of a situation where the suction device 100 and the rod-shaped substrate 150 inserted into the suction device 100 are viewed from above is schematically shown. Figure 8As shown, the inner wall 145 of the receiving portion 140 may also be provided with eight convex portions 145a protruding toward the inner space 141 at equal intervals in the circumferential direction. The portion of the inner wall 145 other than the convex portions 145a is also referred to as a concave portion 145b. The convex portions 145a are provided over the entire region in the up-down direction from the opening 142 to the bottom 143. The concave portions 145b are also provided over the entire region in the up-down direction from the opening 142 to the bottom 143. That is, the cross-sectional shape of the inner wall 145 in the plane orthogonal to the up-down direction is the same as that of the inner wall 145. Figure 8 The shape of the inner wall 145 viewed from above is the same as shown. Figure 8 As shown, the rod-shaped substrate 150 can be supported in a state where at least a part of the side surface of the rod-shaped substrate 150 is separated from the recessed portion 145b. As a result, a gap through which the air flow 190-1 passes can be formed between the side surface of the rod-shaped substrate 150 and the recessed portion 145b. In addition, the recessed portion 145b provided in the inner wall 145 is connected to the recessed portion 143b provided in the bottom portion 143. As a result, the air flow 190-1 and the air flow 190-2 can be connected without obstruction.

[0125] The convex portion 145a may also hold the rod-shaped substrate 150 by pressing the rod-shaped substrate 150. As an example, the width between the opposing convex portions 145a on the plane perpendicular to the up-down direction may be configured to be less than the width of the rod-shaped substrate 150. According to this configuration, the receiving portion 140 can hold the inserted rod-shaped substrate 150 from multiple directions while pressing the opposing convex portions 145a.

[0126] The air flow generated by suction in the suction device 100 has been described above. The configuration of the suction device 100 is not limited to the example described above. Various modifications described below can be applied.

[0127] For example, the number of projections 143a provided on the bottom 143 of the housing 140 is not limited to 1, but may be 2 or more. Also, the number of projections 145a provided on the inner wall 145 of the housing 140 is not limited to 8, but may be any number of 1 or more.

[0128] As another example, the shape of the inner wall 145 of the housing portion 140 is not limited to having projections and depressions in the circumferential direction. Fig. 9 Provide explanation.

[0129] Fig. 9 FIG. 1 is a diagram showing an example of the structure of the inner wall 145 of the storage unit 140 according to the present embodiment. Fig. 9 , an example of a situation where the suction device 100 and the rod-shaped substrate 150 inserted into the suction device 100 are viewed from above is schematically shown. Fig. 9As shown in FIG. 1 , the inner wall 145 of the receiving portion 140 has a pair of planes 145c facing each other. Furthermore, the inner wall 145 of the receiving portion 140 has a pair of arc-shaped curved surfaces 145d connecting the two ends of the plane 145c and facing each other. The pair of planes 145c and the pair of curved surfaces 145d are provided over the entire area in the up-down direction from the opening 142 to the bottom 143. That is, the cross-sectional shape of the inner wall 145 in the plane orthogonal to the up-down direction is the same as that of the inner wall 145 in FIG. Fig. 9 The shape of the inner wall 145 viewed from above is the same as shown. Fig. 9 As shown, the rod-shaped substrate 150 can be supported in a state where at least a part of the side surface of the rod-shaped substrate 150 is separated from the curved surface 145d. As a result, a gap for the air flow 190-1 to pass through can be formed between the side surface of the rod-shaped substrate 150 and the curved surface 145d. In addition, the curved surface 145d provided on the inner wall 145 is connected to the recessed portion 143b provided on the bottom 143. As a result, the air flow 190-1 and the air flow 190-2 can be connected without obstacles. Furthermore, the width between the opposing flat surfaces 145c can be configured to be less than the width of the rod-shaped substrate 150. According to this configuration, the accommodating portion 140 can press and clamp the inserted rod-shaped substrate 150 through the opposing flat surfaces 145c.

[0130] As another example, the form of the air flow generated by the suction in the suction device 100 is not limited to the backflow. Fig.10 and Fig.11 Provide explanation.

[0131] Fig.10 as well as Fig.11 FIG. 2 is a diagram for explaining another example of the air flow generated by suction in the suction device 100 of the present embodiment. Fig.10 as well as Fig.11 , an example of a cross section of the suction device 100 and the rod-shaped substrate 150 inserted into the suction device 100 cut along the vertical direction in a manner passing through the center of the receiving portion 140 is schematically shown. Fig.10 As shown, the suction device 100 may be provided with an air flow path 146 having openings on the side 100c of the suction device 100 and the bottom 143 of the storage portion 140. In addition, the air flow 190 may be generated by passing through the air flow path 146 along with the suction. Fig.11 As shown, the suction device 100 may be provided with an air flow path 146 having openings at the bottom surface 100b of the suction device 100 and the bottom 143 of the receiving portion 140. In addition, along with suction, an air flow 190 may be generated in a manner passing through the air flow path 146. In addition, the opening of the air flow path 146 may be provided at the inner wall 145 of the receiving portion 140 in addition to being provided at the bottom 143 of the receiving portion 140.

[0132] <1.4. Triggering the start of heating>

[0133] The suction device 100 starts heating the rod-shaped substrate 150 based on a predetermined trigger.

[0134] The suction device 100 may also start heating by triggering the button 11 to be pressed in a specified pressing pattern. The pressing pattern is defined by the number of times the button is pressed, the length of time the button is pressed, and the rhythm of the pressing. For example, the suction device 100 may start heating by triggering the button 11 to be pressed twice in a row, or may start heating by triggering the button 11 to be pressed for one second. The suction device 100 may also start heating by triggering the insertion of the rod-type substrate 150. The insertion and removal of the rod-type substrate 150 may be detected by any method. As an example, the insertion and removal of the rod-type substrate 150 may be detected by a proximity sensor. A proximity sensor is a sensor that detects the proximity of an object. As a proximity sensor, various methods may be used, such as a method of radiating waves such as ultrasonic waves or infrared rays and detecting the proximity of an object based on the detection result of the reflected wave, and a method of detecting the proximity of an object based on a change in electrostatic capacitance. Refer to Fig.12 An example of arrangement of the proximity sensor is described. Fig.12 1 is a diagram for explaining an example of the arrangement of the proximity sensor in the suction device 100 of the present embodiment. Fig.12 As shown, the proximity sensor 50 may be arranged near the opening 142 in the inner wall 145 of the receiving portion 140. When the rod-shaped substrate 150 is inserted into the receiving portion 140, the proximity sensor 50 detects that an object is approaching. On the other hand, when the rod-shaped substrate 150 is pulled out of the receiving portion 140, the proximity sensor 50 detects that an object is not approaching. In this way, the proximity sensor 50 can detect the insertion and removal of the rod-shaped substrate 150 by detecting the presence or absence of an approaching object.

[0135] In addition, the sensor for detecting the insertion and removal of the rod-shaped substrate 150 is not limited to the proximity sensor 50. A pressure sensor may be provided together with the proximity sensor 50 or in place of the proximity sensor 50. The pressure sensor may be disposed, for example, at a location that contacts the inserted rod-shaped substrate 150, such as a convex portion 143a provided on the bottom 143 of the receiving portion 140, a convex portion 145a provided on the inner wall 145 of the receiving portion 140, or a flat surface 145c provided on the inner wall 145 of the receiving portion 140. Furthermore, the pressure sensor may detect the insertion and removal of the rod-shaped substrate 150 based on the presence or absence of pressure.

[0136] The suction device 100 may also start heating when the charging device 900 is connected as a trigger. Alternatively, the suction device 100 may also start heating when the charging of the charging device 900 is started as a trigger. The suction device 100 may also start heating when the connection with the charging device 900 is released as a trigger. Alternatively, the suction device 100 may start heating when the charging of the charging device 900 is terminated as a trigger. In addition, the suction device 100 may start heating when the power accumulated in the power supply unit 111 exceeds a predetermined threshold value (for example, a switching threshold value described below) as a result of charging by the charging device 900.

[0137] In addition, which trigger is enabled and which trigger is disabled as a trigger for starting heating can be set to be changeable. The trigger for starting heating can be set, for example, by operating the suction device 100, operating the charging device 900, or remotely operating via an external terminal such as a smartphone.

[0138] In addition, no matter which trigger is activated, it is preferable to start heating under the condition that the rod-shaped substrate 150 is inserted into the suction device 100. This is to prevent so-called dry heating in which the heating unit 121 heats even though the rod-shaped substrate 150 is not inserted into the suction device 100.

[0139] <1.5. Heating based on heating curve>

[0140] The control unit 116 controls the operation of the heating unit 121 based on the heating curve. The control of the operation of the heating unit 121 is achieved by controlling the power supply from the power supply unit 111 to the heating unit 121. The heating unit 121 heats the rod-shaped substrate 150 using the power supplied from the power supply unit 111. The heating curve is control information for controlling the temperature of the heating aerosol source. The heating curve specifies parameters related to the temperature of the heating aerosol source. An example of the temperature of the heating aerosol source is the temperature of the heating unit 121. An example of a parameter related to the temperature of the heating aerosol source is a 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 can also be controlled to change according to the elapsed time from the start of heating. In this case, the heating curve includes information on the time series transition of the specified target temperature. As another example, the heating curve may include parameters that specify the supply method of power to the heating unit 121 (hereinafter also referred to as the power supply parameter). The 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 a feedback control method to be adopted.

[0141] The control unit 116 controls the operation of the heating unit 121 so that the temperature of the heating unit 121 (hereinafter, also referred to as the actual temperature) changes in the same manner as the target temperature specified in the heating curve. Typically, the heating curve is designed so that the flavor that the user tastes becomes optimal when the user inhales the aerosol generated from the rod-shaped substrate 150. Therefore, by controlling the operation of the heating unit 121 based on the heating curve, the flavor that the user tastes can be optimized.

[0142] The temperature control of the heating section 121 can be achieved, for example, by a well-known feedback control. The feedback control can also be, for example, a PID control (Proportional-Integral-Differential Controller). The control section 116 can supply the power from the power supply section 111 to the heating section 121 in the form of pulses through pulse width modulation (PWM) or pulse frequency modulation (PFM). In this case, the control section 116 can perform temperature control of the heating section 121 by adjusting the duty cycle or frequency of the power pulse in the feedback control. Alternatively, the control section 116 can also perform a simple on / off control in the feedback control. For example, the control section 116 can also perform heating of the heating section 121 until the actual temperature reaches the target temperature, interrupt the heating of the heating section 121 when the actual temperature reaches the target temperature, and restart the heating of the heating section 121 when the actual temperature is lower than the target temperature.

[0143] The temperature of the heating section 121 can be quantified, for example, by measuring or estimating the resistance value of the heating section 121 (more precisely, the heating resistor constituting the heating section 121). This is because the resistance value of the heating resistor changes according to the temperature. The resistance value of the heating resistor can be estimated, for example, by measuring the voltage drop in the heating resistor. The voltage drop in the heating resistor can be measured by a voltage sensor that measures the potential difference applied to the heating resistor. In other examples, the temperature of the heating section 121 can be measured by a temperature sensor such as a thermistor disposed near the heating section 121.

[0144] Hereinafter, the period from the start to the end of the process of generating aerosol using the rod-type substrate 150 will also be referred to as a heating period. In other words, the heating period is a period in which the operation of the heating unit 121, that is, the power supply to the heating unit 121, is controlled based on the heating curve. The start time of the heating period is the timing of starting heating based on the heating curve. The end time of the heating period is the timing when a sufficient amount of aerosol is no longer generated. The heating period includes a preparatory heating period in the first half and a puffable period in the second half. The puffable period is a period in which a sufficient amount of aerosol is assumed to be generated. The preparatory heating period is the period from the start of heating to the start of the puffable period. The heating performed during the preparatory heating period is also referred to as preparatory heating.

[0145] The notification unit 113 may also notify the user of information indicating the timing of the end of the preheating. For example, the notification unit 113 notifies the user of information indicating the end of the preheating before the end of the preheating, or notifies the user of information indicating the end of the preheating at the timing of the end of the preheating. The notification to the user can be performed, for example, by lighting up an LED or vibrating. The user can take a puff immediately after the end of the preheating with reference to the notification.

[0146] Similarly, notification unit 113 may notify the user of information indicating the timing of the end of the inhalable period. For example, notification unit 113 notifies the user of information indicating the end of the inhalable period before the end of the inhalable period, or notifies the user of information indicating the end of the inhalable period at the timing of the end of the inhalable period. Notification to the user can be performed, for example, by lighting up an LED or vibrating. The user can take a puff with reference to the notification until the end of the inhalable period.

[0147] Reference Fig.13 An example of a heating curve will be described. Fig.13 70 is a graph schematically showing an example of a heating curve of the present embodiment. The horizontal axis of the graph 70 is time. The vertical axis of the graph 70 is temperature. Line 71 represents the time series change of the target temperature. Fig.13 As shown, the heating period may also include an initial heating period, an intermediate cooling period and a re-heating period in sequence.

[0148] The initial temperature rise period is the first period of the heating period, and is a period during which the temperature of the heating portion 121 rises from the initial temperature. The initial temperature is the temperature of the heating portion 121 when heating starts. During the initial temperature rise period, the temperature of the heating portion 121 rises rapidly and is maintained at a high temperature.

[0149] The midway temperature drop period is a period following the initial temperature rise period, and is a period during which the temperature of the heating unit 121 drops. The suction device 100 may interrupt the supply of power to the heating unit 121 during the midway temperature drop period.

[0150] The reheating period is a period following the intermediate temperature drop period, and is a period during which the temperature of the heating unit 121 rises again. Typically, the temperature rise rate of the heating unit 121 during the reheating period is set slower than the temperature rise rate of the heating unit 121 during the initial temperature rise period.

[0151] exist Fig.13 In the example shown, the target temperature rises rapidly to around 300°C during the initial temperature rise period, then drops to around 230°C during the intermediate temperature drop period, and then rises in stages to around 260°C during the re-temperature rise period. Fig.13In the example shown, the period from the start of heating to the middle of the initial temperature rise period is the preparatory heating period, and the period from the middle of the initial temperature rise period to the end of the re-temperature rise period is the puffable period.

[0152] <1.6. Power Supply from Charging Device 900 to Suction Device 100>

[0153] Even if the suction device 100 starts heating the rod-shaped substrate 150 when the power stored in the power supply unit 111 is low, it may be difficult to continue heating until the end of the heating period. In the case where heating is stopped in the middle of the heating period, the quality of user experience is significantly deteriorated. Therefore, in order to prevent such deterioration in the quality of user experience, the aerosol generating system 1 performs the processing described below.

[0154] The charging device 900 may also charge the suction device 100 when the suction device 100 is connected to the charging device 900. That is, the power supply unit 911 may supply power to the power supply unit 111 to charge the power supply unit 111 when the suction device 100 is connected to the charging device 900.

[0155] The charging device 900 may also supply power for heating to the suction device 100 when the suction device 100 performs heating while the suction device 100 is connected to the charging device 900. That is, the power supply unit 911 may also supply power to the heating unit 121 when the suction device 100 is connected to the charging device 900. Furthermore, the heating unit 121 may also heat the rod-shaped substrate 150 using the power supplied from the power supply unit 911.

[0156] The charging device 900 may also supply power for heating to the suction device 100 after stopping charging of the suction device 100 when the suction device 100 is connected to the charging device 900 and the suction device 100 is performing heating. Alternatively, the charging device 900 may also supply power for heating to the suction device 100 while charging the suction device 100 when the suction device 100 is performing heating. That is, the power supply unit 911 can supply power to at least one of the power supply unit 111 and the heating unit 121 when the suction device 100 is connected to the charging device 900.

[0157] However, when the heating unit 121 performs heating in a state where the suction device 100 is connected to the charging device 900, the control unit 116 selects the power supply source from the power supply unit 111 or the power supply unit 911 to the heating unit 121 based on the power stored in the suction device 100. As an example, the control unit 116 may also select the power supply unit 911 as the power supply source to the heating unit 121 when the power stored in the power supply unit 111 is less than a threshold value (hereinafter also referred to as a switching threshold value). As another example, the control unit 116 may also select the power supply unit 111 as the power supply source to the heating unit 121 when the power stored in the power supply unit 111 is greater than the switching threshold value. The switching threshold value corresponds to the power that can continue heating until the end of the heating period. According to this configuration, when it is difficult to continue heating until the end of the heating period only by the power stored in the power supply unit 111, the suction device 100 can receive the power supply from the power supply unit 911 and continue heating until the end of the heating period. As a result, the quality of user experience can be improved. Alternatively, when the power supply unit 911 is selected as the power supply source for the heating unit 121, the power supply unit 911 supplies power only to the heating unit 121. That is, the charging device 900 may also cause the suction device 100 to perform heating. Alternatively, when the power supply unit 911 is selected as the power supply source for the heating unit 121, the power supply unit 911 supplies power to both the heating unit 121 and the power supply unit 111. That is, the charging device 900 may also cause the suction device 100 to perform heating while charging the suction device 100.

[0158] The control unit 116 may also dynamically set the switching threshold. Specifically, the control unit 116 may also set different switching thresholds before and during the heating. Furthermore, the control unit 116 may also change the switching threshold according to the progress of heating during the heating. As an example, the control unit 116 sets the switching threshold to a value that can be continuously heated from the beginning to the end of the heating period before performing heating based on the heating curve. As another example, the control unit 116 sets the switching threshold to a value that can be continuously heated to the end of the remaining period of the heating period during the heating based on the heating curve. In this case, the more the heating progresses, that is, the shorter the remaining time of the heating period, the more the control unit 116 reduces the switching threshold. According to this configuration, the switching threshold can be dynamically set according to whether the heating is performed before or during the heating, and then during the heating according to the progress of the heating. As a result, it is possible to more accurately determine whether it is possible to continue heating until the end of the heating period only by the power accumulated in the power supply unit 111.

[0159] The control unit 116 may also select the power supply unit 911 as the power supply source for the heating unit 121 during at least a portion of the heating period when the power stored in the power supply unit 111 is less than the switching threshold. According to this configuration, it is possible to prevent the power stored in the power supply unit 111 from decreasing during at least a portion of the heating period.

[0160] At least a portion of the heating time period described above may also include a period during which power consumption is relatively large (hereinafter also referred to as a high-load period). That is, the suction device 100 may also select the power supply unit 911 as the power supply source to the heating unit 121 during the high-load period when the power stored in the power supply unit 111 is less than the switching threshold. An example of a high-load period is a period in the initial temperature rise period that includes a period during which the temperature of the heating unit 121 rises and excludes a period during which the temperature of the heating unit 121 is maintained. Another example of a high-load period is the initial temperature rise period. Another example of a high-load period is the preparatory heating period. According to this configuration, by setting the power supply source to the heating unit 121 during the high-load period to the power supply unit 911, it is possible to effectively prevent the power stored in the power supply unit 111 from being reduced.

[0161] The control unit 116 may also select the power supply unit 111 as the power supply source for the heating unit 121 when the prescribed conditions are met during a period other than the high load period. Furthermore, the control unit 116 may also select the power supply unit 911 as the power supply source for the heating unit 121 when the prescribed conditions are not met. That is, the control unit 116 may continue to select the power supply unit 911 as the power supply source for the heating unit 121 until the prescribed conditions are met after the high load period ends, and switch the power supply source for the heating unit 121 to the power supply unit 111 when the prescribed conditions are met. According to this configuration, the power supply source for the heating unit 121 can be switched from the power supply unit 911 to the power supply unit 111 at an appropriate timing, and heating can be continued until the end of the heating period.

[0162] The above-mentioned predetermined conditions may also include that the connection between the suction device 100 and the charging device 900 is released. That is, the suction device 100 may also set the power supply source to the heating unit 121 to the power supply unit 911 until the connection between the suction device 100 and the charging device 900 is released, and switch to the power supply unit 111 after the release. According to this configuration, heating can be continued even after the connection between the suction device 100 and the charging device 900 is released.

[0163] The above-mentioned conditions may also include that the power stored in the power supply unit 111 becomes equal to or greater than the switching threshold. That is, the suction device 100 may also set the power supply unit 911 as the power supply source for the heating unit 121 until the power stored in the power supply unit 111 becomes equal to or greater than the switching threshold, and switch to the power supply unit 111 after the power becomes equal to or greater than the switching threshold. According to this configuration, heating based on the power supply from the power supply unit 911 can be continued until the power stored in the power supply unit 111 becomes equal to or greater than the switching threshold.

[0164] The predetermined condition may include the end of the high load period. That is, the suction device 100 may automatically switch the power supply source to the heating unit 121 from the power supply unit 911 to the power supply unit 111 when the high load period ends.

[0165] The predetermined conditions may include at least one of the conditions exemplified above.

[0166] The notification unit 113 or the notification unit 913 may also notify information indicating that the connection between the suction device 100 and the charging device 900 can be released when the power stored in the power supply unit 111 becomes equal to or greater than the switching threshold. The user can use the suction device 100 and the charging device 900 independently by referring to the notification. According to this configuration, the quality of user experience can be further improved.

[0167] Furthermore, the aerosol generating system 1 may be operated so that electric power equal to or greater than the switching threshold is accumulated in the power supply unit 111 at the end of the high load period.

[0168] For example, when the heating unit 121 performs heating in a state where the suction device 100 is connected to the charging device 900, the power supply unit 911 can increase the voltage applied to the power supply unit 111 compared to the case where the heating unit 121 does not perform heating. According to this configuration, the power supply unit 111 can be quickly charged until the high load period ends. As a result, the power supply unit 111 can accumulate power exceeding the switching threshold at the stage when the high load period ends.

[0169] As another example, the control unit 116 may prohibit heating when the suction device 100 is connected to the charging device 900 until the power supply unit 111 is charged with power exceeding the switching threshold. Furthermore, the control unit 116 may allow heating when power exceeding the switching threshold is charged to the power supply unit 111. According to this configuration, the suction device 100 can limit the start of heating when power exceeding the switching threshold is accumulated in the power supply unit 111.

[0170] When the aerosol generating system 1 operates as described above, the notification unit 113 or the notification unit 913 may use the end of the high load period as a trigger to notify information indicating that the suction device 100 and the charging device 900 can be disconnected. The user can disconnect the suction device 100 and the charging device 900 with reference to the notification and use the suction device 100 alone. According to this configuration, the quality of user experience can be further improved.

[0171] The above describes an example in which the aerosol generating system 1 operates so that the power supply unit 111 accumulates power equal to or greater than the switching threshold value at the end of the high load period. Other supplementary matters will be described below.

[0172] The power supply unit 911 may start supplying power to the heating unit 121 when the suction device 100 is connected to the charging device 900 and the rod-shaped substrate 150 is inserted into the suction device 100. Similarly, the power supply unit 911 may start supplying power to the heating unit 121 when the suction device 100 is connected to the charging device 900 and the rod-shaped substrate 150 is inserted into the suction device 100. That is, the power supply unit 911 may start supplying power to the heating unit 121 when the two conditions of connection between the suction device 100 and the charging device 900 and insertion of the rod-shaped substrate 150 into the suction device 100 are satisfied. According to this configuration, the user can start heating without pressing the button 91 or the like.

[0173] When the suction device 100 is connected to the charging device 900, as described above, the power supply unit 911 may supply power to the power supply unit 111, may supply power to the heating unit 121, or may supply power to both the power supply unit 111 and the heating unit 121. The control unit 916 may also set whether the power supply unit 911 supplies power to the power supply unit 111, to the heating unit 121, or to both the power supply unit 111 and the heating unit 121 based on the user operation of the charging device 900 when the suction device 100 is connected to the charging device 900. For example, the charging device 900 may switch these settings when the button 91 is pressed in a prescribed pressing pattern. According to this configuration, power supply that meets the user's intention can be achieved.

[0174] When the suction device 100 is connected to the charging device 900, the notification unit 913 of the charging device 900 may also notify the power stored in the power supply unit 111 (i.e., the progress of charging) and / or the progress of heating by the heating unit 121. On the other hand, when the suction device 100 is disconnected from the charging device 900, the notification unit 113 of the suction device 100 may also notify the power stored in the power supply unit 111 and / or the progress of heating by the heating unit 121. Fig.14 An example of the flow of the above-described processing will be described. Fig.14 This is a flowchart showing an example of the flow of processing executed by the aerosol generating system 1 of the present embodiment.

[0175] like Fig.14 As shown, first, the control unit 116 detects the connection between the suction device 100 and the charging device 900 (step S102). For example, the control unit 116 detects the connection between the suction device 100 and the charging device 900 based on the magnetic field of the magnetic portion 93 detected by the Hall sensor and / or the presence or absence of the electrical connection between the electrical contact 14 and the electrical contact 94.

[0176] Next, the control unit 116 starts charging the power supply unit 111 using the power supplied from the charging device 900 (step S104 ). That is, the power supply unit 911 supplies power to the power supply unit 111 , and the power supply unit 111 is charged.

[0177] Next, the control unit 116 determines whether a user operation instructing the start of heating is detected (step S106). An example of a user operation instructing the start of heating is pressing the button 91. Another example of a user operation instructing the start of heating is inserting the rod-shaped substrate 150 into the suction device 100. The control unit 116 waits until a user operation instructing the start of heating is detected (step S106: No). When a user operation instructing the start of heating is detected (step S106: Yes), the control unit 116 starts heating based on the heating curve using the power supplied from the charging device 900 (step S108). That is, the power supply unit 911 supplies power to the heating unit 121. Then, the heating unit 121 starts heating based on the heating curve using the power supplied from the power supply unit 911.

[0178] Next, the control unit 116 determines whether the power stored in the power supply unit 111 is equal to or greater than the switching threshold (step S110 ). The control unit 116 waits until the power stored in the power supply unit 111 becomes equal to or greater than the switching threshold (step S110 : No).

[0179] When it is determined that the power stored in the power supply unit 111 is equal to or greater than the switching threshold (step S110: Yes), the notification unit 913 notifies information indicating that the connection between the suction device 100 and the charging device 900 can be released (step S112). For example, the LED 92 emits light in a predetermined light emission pattern. Next, the control unit 116 determines whether the connection between the suction device 100 and the charging device 900 is released (step S114). The control unit 116 waits until the connection between the suction device 100 and the charging device 900 is released (step S114: No).

[0180] When it is determined that the connection between the suction device 100 and the charging device 900 is released (step S114: Yes), the control unit 116 switches the power supply source to the heating unit 121 from the power supply unit 911 to the power supply unit 111 (step S116). That is, the power supply unit 111 starts to supply power to the heating unit 121. Then, the heating unit 121 continues heating based on the heating curve using the power supplied from the power supply unit 111.

[0181] Next, the control unit 116 determines whether the termination condition is satisfied (step S118). An example of the termination condition is that heating is performed to the end of the heating period. Another example of the termination condition is that the number of puffs reaches a predetermined number. The control unit 116 waits until the termination condition is satisfied (step S118: No).

[0182] When it is determined that the end condition is satisfied (step S118 : Yes), the control unit 116 ends the heating (step S120 ).

[0183] <1.7. Switching of heating curve>

[0184] The suction device 100 may also switch the heating curve used when heating the rod-shaped substrate 150. Hereinafter, as an example, an example in which the suction device 100 selects a heating curve to be used from two heating curves will be described. Of course, the suction device 100 may also select a heating curve to be used from three or more heating curves.

[0185] The control unit 116 can select a heating curve to be used from the first heating curve or the second heating curve. An example of the first heating curve is Fig.13 The heating curve is shown. Fig.15 An example of the second heating curve will be described.

[0186] Fig.15 72 is a graph schematically showing an example of a heating curve of the present embodiment. The horizontal axis of the graph 72 is time. The vertical axis of the graph 72 is temperature. Line 73 represents the time series change of the target temperature. Fig.15 As shown, the heating period may also include an initial heating period, an intermediate cooling period, and a reheating period in sequence. Fig.15 In the example shown, the target temperature rises rapidly to about 250°C during the initial temperature rise period, then drops to about 180°C during the intermediate temperature drop period, and then rises in stages to about 220°C during the re-temperature rise period. Fig.15 In the example shown, the period from the start of heating to the middle of the initial temperature rise period is the preparatory heating period, and the period from the middle of the initial temperature rise period to the end of the re-temperature rise period is the puffable period.

[0187] If you compare Fig.13The first heating curve and Fig.15 The second heating curve shown can be said that the first heating curve is a high temperature heating curve, and the second heating curve is a low temperature heating curve. In this way, the high temperature heating curve and the low temperature heating curve can be switched, so that the user can enjoy the suction feeling corresponding to the mood.

[0188] The control unit 116 may also select the heating curve to be used based on the user operation of the suction device 100. As an example, the pressing mode of the button 11 may be made to correspond to the first heating curve and the second heating curve respectively. Moreover, the control unit 116 may also select the heating curve corresponding to the pressing mode when the button 11 is pressed as the heating curve to be used. For example, the control unit 116 may also select the first heating curve as the heating curve to be used when the button 11 is pressed once or when the button 11 is pressed for a short time. In addition, the control unit 116 may also select the second heating curve as the heating curve to be used when the button 11 is pressed twice or when the button 11 is pressed for a long time. As another example, the control unit 116 may also switch the heating curve to be used from the first heating curve to the second heating curve, or from the second heating curve to the first heating curve, when the button 11 is pressed in a prescribed pressing mode.

[0189] The control unit 116 may also select the heating curve to be used based on the user operation on the charging device 900. As an example, the pressing pattern of the button 91 may be made to correspond to the first heating curve and the second heating curve, respectively. Moreover, the control unit 116 may also select the heating curve corresponding to the pressing pattern when the button 91 is pressed as the heating curve to be used. For example, the control unit 116 may also select the first heating curve as the heating curve to be used when the button 91 is pressed once, or when the button 91 is pressed for a short time. In addition, the control unit 116 may also select the second heating curve as the heating curve to be used when the button 91 is pressed twice, or when the button 91 is pressed for a long time. As another example, the control unit 116 may also switch the heating curve to be used from the first heating curve to the second heating curve, or from the second heating curve to the first heating curve, when the button 91 is pressed in a specified pressing pattern.

[0190] In addition, when the suction device 100 is not connected to the charging device 900, the control unit 116 may select the heating curve to be used based on the user operation of the suction device 100. On the other hand, when the suction device 100 is connected to the charging device 900, the control unit 116 may select the heating curve to be used based on the user operation of the charging device 900. After setting the heating curve to be used, the suction device 100 starts heating based on the set heating curve based on an arbitrary trigger. The trigger for starting heating is as described above. In addition, the suction device 100 may start heating based on the setting of the heating curve as a trigger.

[0191] The control unit 116 can set a heating curve used when the suction device 100 is connected to the charging device 900 and a heating curve used when the suction device 100 is not connected to the charging device 900. For example, the control unit 116 can also use a first heating curve when the suction device 100 is connected to the charging device 900, and use a second heating curve when the suction device 100 is not connected to the charging device 900.

[0192] In addition, the control unit 116 may switch the heating curve to be used based on the trigger for starting heating. As an example, the control unit 116 may use the first heating curve when starting heating based on the user operation on the suction device 100, and use the second heating curve when starting heating based on the user operation on the charging device 900. As another example, the control unit 116 may use the first heating curve when starting heating based on the pressing of the button 11, and use the second heating curve when starting heating based on the insertion of the rod-shaped substrate 150.

[0193] Here, the control unit 116 may also switch the heating curve used during the execution of heating based on the heating curve. The control unit 116 may also switch the heating curve used when the user operation described above is performed on the suction device 100 or the charging device 900 during the execution of heating based on the heating curve. As an example, the control unit 116 may also switch the heating curve used to the second heating curve during the execution of heating based on the first heating curve. Of course, it may also be set to the opposite.

[0194] However, when the control unit 116 switches the heating curve to be used, the heating time before the switch is continued, and the operation of the heating unit 121 is controlled from the middle with reference to the heating curve after the switch. For example, when the control unit 116 switches the heating curve when 120 seconds have passed since the start of heating, the operation of the heating unit 121 is controlled based on the time series transition of the target temperature after 120 seconds have passed since the start of heating in the heating curve after the switch. According to this configuration, the switching of the heating curve in the middle of the heating period can be smoothly implemented. As an example, referring to Fig.16 An example in which the heating curve to be used is switched to the first heating curve during execution of heating based on the second heating curve will be described.

[0195] Fig.16 74 is a graph schematically showing an example of switching of the heating curve of the present embodiment. The horizontal axis of the graph 74 is time. The vertical axis of the graph 74 is temperature. Line 71 represents the time series transition of the target temperature specified by the first heating curve. Line 73 represents the time series transition of the target temperature specified by the second heating curve. Line 75 represents the time series transition of the target temperature when the heating curve used is switched to the first heating curve 120 seconds after the start of heating based on the second heating curve. As shown in line 75, the target temperature transitions as specified by the second heating curve from the start of heating to 120 seconds. Thereafter, the target temperature passes as specified by the first heating curve through a transition period in which the difference in the target temperature between the second heating curve and the first heating curve is smoothly filled.

[0196] <1.8. Information Notification>

[0197] The charging device 900 (for example, the notification unit 913) may also notify information indicating the state of the suction device 100. In particular, the notification unit 913 of the charging device 900 may also notify information indicating the state of the suction device 100 when the suction device 100 is connected to the charging device 900. As an example, the LED 92 may also notify information indicating the state of the suction device 100. If it is considered that the LED 12 is shielded when the suction device 100 is connected to the charging device 900, the usability can be improved by this configuration.

[0198] The LED 92 notifies information indicating the state of the suction device 100 by emitting light in a lighting pattern corresponding to the state of the suction device 100. The lighting pattern is defined by at least one of the number, position, shape, color, lighting frequency, lighting time, and blinking rhythm of the illuminated regions.

[0199] (1) Information showing the progress of heating

[0200] The notification unit 913 may also notify information indicating the progress of heating by the suction device 100 (specifically, the heating unit 121). In particular, the LED 92 may also notify information indicating the progress of heating by the suction device 100. When heating is started by pressing the button 91 as a trigger, the progress of heating can be notified to the user intuitively by notifying information indicating the progress of heating using the LED 92 arranged so as to surround the pressed button 91. Fig.17 as well as Fig.18 An example of information indicating the progress of heating by the suction device 100 and notified by the LED 92 will be described.

[0201] Fig.17 9 is a diagram for explaining an example of information notified by LED 92 of charging device 900 according to the present embodiment. Fig.17 , the button 91 and the LED 92 are shown as viewed from above. Fig.17 As shown, LED92 can be configured in a ring shape so as to surround the button 91 whose top surface is configured in a circular shape. LED92 has a plurality of light-emitting areas 921 (921-1 to 921-8). Light-emitting areas 921-1 to 921-4 are four arc-shaped areas obtained by dividing the inner area of ​​the LED92 configured in a ring shape by 90 degrees in the circumferential direction. Light-emitting areas 921-5 to 921-8 are arc-shaped areas located on the outer sides of the light-emitting areas 921-1 to 921-4, respectively. When the light-emitting areas 921-1 to 921-4 emit light, the light-emitting areas 921-1 to 921-4 emit light as a whole. On the other hand, when the light-emitting areas 921-5 to 921-8 emit light, a plurality of lines extending radially with the button 91 as the center emit light.

[0202] exist Fig.17 , light-emitting modes 60a to 60e are illustrated. Light-emitting mode 60a is a light-emitting mode in which light-emitting areas 921-1 and 921-5 emit light. Light-emitting mode 60b is a light-emitting mode in which light-emitting areas 921-1, 921-2, and 921-6 emit light. Light-emitting mode 60c is a light-emitting mode in which light-emitting areas 921-1 to 921-3 and 921-7 emit light. Light-emitting mode 60d is a light-emitting mode in which light-emitting areas 921-1 to 921-4 and 921-8 emit light. Light-emitting mode 60e is a light-emitting mode in which light-emitting areas 921-1 to 921-4 emit light.

[0203] LED 92 may also switch the light mode from light mode 60a to light mode 60e in sequence and emit light according to the progress of heating of the suction device 100 during the period immediately after the heating starts. As an example, the length of the preparatory heating period is 20 seconds. In this case, LED 92 may also emit light in light mode 60a 5 seconds after the start of heating, in light mode 60b 5 seconds thereafter, in light mode 60c 5 seconds thereafter, and in light mode 60d 5 seconds thereafter. After a period of 20 seconds has passed since the start of heating as the preparatory heating period, LED 92 may also emit light in light mode 60e. By referring to such a transition of light modes, the user can easily grasp the remaining time of the preparatory heating period.

[0204] Fig.18 9 is a diagram for explaining an example of information notified by LED 92 of charging device 900 according to the present embodiment. Fig.18 , the button 91 and the LED 92 are shown as viewed from above. Fig.18 The structure of the button 91 and LED 92 shown is as described above. Fig.17 As described.

[0205] exist Fig.18 , light emission patterns 61a to 61e are shown. Light emission pattern 61a is the same as light emission pattern 60e. Light emission pattern 61b is the same as light emission pattern 60d. Light emission pattern 61c is the same as light emission pattern 60c. Light emission pattern 61d is the same as light emission pattern 60b. Light emission pattern 61e is the same as light emission pattern 60a.

[0206] LED 92 may also switch the light mode from light mode 61a to light mode 61e in sequence and emit light in accordance with the progress of heating by the suction device 100 before the end of heating. As an example, LED 92 may emit light in light mode 61a from the end of the pre-heating period to 20 seconds before the end of heating. LED 92 may also emit light in light mode 61b for 5 seconds from 20 seconds before the end of heating, emit light in light mode 61c for the next 5 seconds, emit light in light mode 61d for the next 5 seconds, and emit light in light mode 61e for the next 5 seconds. By referring to such a change in light mode, the user can easily grasp the remaining time until the end of heating.

[0207] Above, refer to Fig.17 as well as Fig.18 An example of information indicating the progress of heating of the suction device 100 notified by the LED 92 has been described. Fig.19 Another example of the information indicating the progress of heating of the suction device 100 notified by the LED 92 will be described.

[0208] Fig.19 9 is a diagram for explaining an example of information notified by LED 92 of charging device 900 according to the present embodiment. Fig.19 , the button 91 and the LED 92 are shown as viewed from above. Fig.19 The structure of the button 91 and LED 92 shown is as described above. Fig.17 As described.

[0209] exist Fig.19 , light-emitting modes 62a to 62e are illustrated. Light-emitting mode 62a is a light-emitting mode in which light-emitting areas 921-1 to 921-3 and 7 emit light. Light-emitting mode 62b is a light-emitting mode in which light-emitting areas 921-2 to 921-4 and 921-8 emit light. Light-emitting mode 62c is a light-emitting mode in which light-emitting areas 921-1, 921-3, 921-4 and 921-5 emit light. Light-emitting mode 62d is a light-emitting mode in which light-emitting areas 921-1, 921-2, 921-4 and 921-6 emit light. Light-emitting mode 62e is a light-emitting mode in which light-emitting areas 921-1 to 921-4 emit light.

[0210] LED 92 may also switch the light mode from light mode 62a to light mode 62d sequentially and repeatedly during the preheating period and emit light. Moreover, LED 92 may also emit light in light mode 62e after the preheating period ends. By referring to such a change in light mode, the user can easily understand whether the preheating period is in progress or has ended. Fig.19 Another example of the information indicating the progress of heating of the suction device 100 notified by the LED 92 has been described.

[0211] Of course, the information indicating the progress of heating of the suction device 100 may also be notified by a method other than the position of the light emitting area 921 of the LED 92. In addition, the LED 92 may also notify the information indicating the progress of heating of the suction device 100 by the light emitting color of the LED 92. For example, the LED 92 may also switch the light emitting color to red, yellow, and then blue in sequence according to the progress of heating of the suction device 100 during the period immediately after the heating starts. Moreover, the LED 92 may also switch the light emitting color to blue, yellow, and then red in sequence according to the progress of heating of the suction device 100 during the period immediately before the heating ends. As described above, the suction device 100 is capable of switching the heating curve used when heating the rod-shaped substrate 150. Therefore, the LED 92 may also emit light in a light emitting pattern corresponding to the heating curve used by the suction device 100. For example, the LED 92 may also make the light emitting color and / or the position of the light emitting area 921 different when the suction device 100 uses the first heating curve and when the second heating curve is used. As an example, when the suction device 100 uses the first heating curve, the LED 92 may also notify the reference Fig.17 as well as Fig.18 The above-described information indicating the progress of heating of the suction device 100 is provided. On the other hand, when the suction device 100 uses the second heating curve, the LED 92 may also notify the reference Fig.19 The above-described information indicates the progress of heating by the suction device 100. The user can easily understand which heating curve is used by referring to such notification.

[0212] (2) Information indicating charging status

[0213] The notification unit 913 may also notify information indicating the charging state of the suction device 100 (specifically, the power supply unit 111). That is, the notification unit 913 may also notify information indicating the power stored in the power supply unit 111. In particular, the LED 92 may also notify information indicating the charging state of the suction device 100. Fig. 20 An example of information indicating the charging state of the suction device 100 notified by the LED 92 will be described.

[0214] Fig. 20 9 is a diagram for explaining an example of information notified by LED 92 of charging device 900 according to the present embodiment. Fig. 20 , the button 91 and the LED 92 are shown as viewed from above. Fig. 20 The structure of the button 91 and LED 92 shown is as described above. Fig.17 As described.

[0215] exist Fig. 20, light-emitting modes 63a to 63e are illustrated. Light-emitting mode 63a is a light-emitting mode in which light-emitting areas 921-1 to 921-4 emit light. Light-emitting mode 63b is a light-emitting mode in which light-emitting areas 921-1 to 921-3 emit light. Light-emitting mode 63c is a light-emitting mode in which light-emitting areas 921-1 and 921-2 emit light. Light-emitting mode 63d is a light-emitting mode in which light-emitting area 921-1 emits light. Light-emitting mode 63e is a light-emitting mode in which light-emitting areas 921-1 and 921-5 emit light.

[0216] LED92 emits light in any one of the light emission modes 63a to 63e according to the power stored in the power supply unit 111. As an example, LED92 may emit light in the light emission mode 63a when the power stored in the power supply unit 111 is 80 to 100% of the fully charged state, emit light in the light emission mode 63b when it is 60 to 80%, and emit light in the light emission mode 63c when it is 40 to 60%. In addition, LED92 may emit light in the light emission mode 63d when the power stored in the power supply unit 111 is 20 to 40% of the fully charged state, and emit light in the light emission mode 63e when it is 0 to 20%. In this case, as the power stored in the power supply unit 111 decreases, LED92 switches the light emission mode from the light emission mode 63a to 63e in sequence and emits light. On the other hand, as the power stored in the power supply unit 111 increases due to charging, LED92 switches the light emission mode from the light emission mode 63e to 63a in sequence and emits light. By referring to such notification, the user can easily understand whether charging is necessary or the progress of charging.

[0217] Of course, the information indicating the charging state of the suction device 100 may be notified by a method other than the position of the light emitting area 921 of the LED 92. In addition, the LED 92 may also notify the information indicating the charging state of the suction device 100 by the light emission color of the LED 92. For example, the LED 92 may emit blue light when the power stored in the power supply unit 111 is 50 to 100% of the full charge state, emit yellow light when it is 20 to 50%, and emit red light when it is 0 to 20%.

[0218] As information indicating the charging state of the suction device 100, the LED 92 may also notify information indicating the number of times that heating based on the heating curve can be performed using the power stored in the power supply unit 111 (hereinafter also referred to as the remaining number of heating times). As an example, the LED 92 may also emit light in the light emission mode 63a when the remaining number of heating times is 20 times or more, emit light in the light emission mode 63b when the remaining number of heating times is 15 to 19 times, and emit light in the light emission mode 63c when the remaining number of heating times is 10 to 14 times. In addition, the LED 92 may also emit light in the light emission mode 63d when the remaining number of heating times is 5 to 9 times, and emit light in the light emission mode 63e when the remaining number of heating times is 4 times or less.

[0219] In addition, the charging device 900 may also notify information indicating the charging state of the charging device 900. That is, the charging device 900 may also notify information indicating the power stored in the power supply unit 911. The information indicating the charging state of the charging device 900 may be notified in the same manner as the information indicating the charging state of the suction device 100.

[0220] (3) Error

[0221] The notification unit 913 may also notify information indicating an error that has occurred in the suction device 100. In particular, the LED 92 may also notify information indicating an error that has occurred in the suction device 100. Fig.21 An example of information indicating an error occurring in the suction device 100 and notified by the LED 92 will be described.

[0222] Fig.21 9 is a diagram for explaining an example of information notified by LED 92 of charging device 900 according to the present embodiment. Fig.21 , the button 91 and the LED 92 are shown as viewed from above. Fig.21 The structure of the button 91 and LED 92 shown is as described above. Fig.17 As described.

[0223] exist Fig.21 , light emission patterns 64a to 64d are illustrated. Light emission pattern 64a is a light emission pattern in which light emission areas 921-1, 921-4, 921-5, and 921-8 emit light. Light emission pattern 64b is a light emission pattern in which light emission areas 921-2, 921-3, 921-6, and 921-7 emit light. Light emission pattern 64c is a light emission pattern in which light emission areas 921-1, 921-2, 921-5, and 921-6 emit light. Light emission pattern 64d is a light emission pattern in which light emission areas 921-3, 921-4, 921-7, and 921-8 emit light.

[0224] The LED 92 may also emit light in the light pattern 64a when a first error occurs in the suction device 100, emit light in the light pattern 64b when a second error occurs, emit light in the light pattern 64c when a third error occurs, and emit light in the light pattern 64d when a fourth error occurs. An example of the first error is that the temperature of the power supply unit 111 is extremely low. An example of the second error is that the temperature of the power supply unit 111 is extremely high. An example of the third error is that the temperature of the heating unit 121 is extremely low. An example of the fourth error is that the temperature of the heating unit 121 is extremely high.

[0225] Of course, the information indicating the error occurring in the suction device 100 may be notified by a method other than the position of the light emitting area 921 of the LED 92. In addition, the LED 92 may also notify the information indicating the error occurring in the suction device 100 by the light emitting color of the LED 92. For example, the LED 92 may also emit light in a color corresponding to the error occurring in the suction device 100.

[0226] In addition, the charging device 900 may notify information indicating an error occurring in the charging device 900. The information indicating an error occurring in the charging device 900 may be notified by the same method as the information indicating an error occurring in the suction device 100.

[0227] (4) Notification Timing

[0228] There are various possible triggers for notifying the information indicating the state of the suction device 100 .

[0229] As an example, information indicating the progress of heating of the suction device 100 may be notified while the suction device 100 is performing heating. In addition, information indicating the charging state of the suction device 100 may be notified while the suction device 100 is being charged. In addition, information indicating an error occurring in the suction device 100 may be notified when the suction device 100 is connected to the charging device 900 while an error occurs in the suction device 100.

[0230] As another example, the pressing of the button 91 may be used as a trigger to notify information indicating the state of the suction device 100. However, different information may be notified according to the pressing mode of the button 91. Specifically, when the button 91 is pressed in the first pressing mode, information indicating the progress of the heating of the suction device 100 may be notified. When the button 91 is pressed in the second pressing mode, information indicating the charging state of the suction device 100 may be notified. Then, when the button 91 is pressed in the third pressing mode, information indicating an error occurring in the suction device 100 may be notified. The first pressing mode, the second pressing mode, and the third pressing mode are different from each other. However, the first pressing mode may be the same as the pressing mode indicating the start of heating.

[0231] As another example, the connection between the suction device 100 and the charging device 900 or the disconnection between the suction device 100 and the charging device 900 may be used as a trigger to notify the information indicating the state of the suction device 100. In addition, the power off, power on, sleep or recovery from sleep of the suction device 100 may be used as a trigger to notify the information indicating the state of the suction device 100.

[0232] (5) Supplement

[0233] The information indicating the state of the suction device 100 may be notified by the suction device 100 instead of the charging device 900 or together with the charging device 900. In particular, the notification unit 113 of the suction device 100 may also notify the information indicating the state of the suction device 100 when the suction device 100 and the charging device 900 are not connected. As an example, the LED 12 may also notify the information indicating the state of the suction device 100. The LED 12 can notify the information indicating the state of the suction device 100 in the same manner as the method in which the LED 92 notifies the information indicating the state of the suction device 100 described above.

[0234] In addition, the suction device 100 may also notify information indicating the state of the charging device 900. In particular, the suction device 100 may also notify information indicating the state of the charging device 900 when connected to the charging device 900. As an example, the LED 12 may also notify information indicating the state of the charging device 900. As the information indicating the state of the charging device 900 notified by the suction device 100, information indicating the charging state of the charging device 900 and information indicating an error occurring in the charging device 900 may be listed.

[0235] <2. Modifications>

[0236] The embodiments of the present disclosure have been described above. Various modifications of the present disclosure will be described below.

[0237] <2.1. First Modification>

[0238] As described above, the cover 20 and the main body 30 can be configured to be detachable. There are many possible attachment and detachment mechanisms for the cover 20 and the main body 30. Figure 22 to Figure 29 , an example of a mounting and dismounting mechanism between the cover 20 and the main body 30 will be described.

[0239] (1)First example

[0240] Fig. 22 This is a diagram for explaining a first example of the attachment and detachment mechanism of the suction device 100 according to the present modification. Fig.23This is a diagram schematically showing an example of a cross section of the suction device 100 in a state where the connection between the cover 20 and the main body 30 is released in the first example of the attachment and detachment mechanism. Fig.24 1 is a diagram schematically showing an example of a cross section of the suction device 100 in a state where the cover 20 and the main body 30 are connected in the first example of the attachment and detachment mechanism. Fig.23 as well as Fig.24 , an example of a cross section of the suction device 100 cut along the vertical direction in a manner passing through the center of the receiving portion 140 is schematically shown. Figure 22 to Figure 24 As shown, the cover 20 and the main body 30 are connected in a manner that the bottom surface 20b of the cover 20 overlaps the top surface 30a of the main body 30. The top surface 20a of the cover 20 constitutes the top surface 100a of the suction device 100. The bottom surface 30b of the main body 30 constitutes the bottom surface 100b of the suction device 100. When the cover 20 and the main body 30 are connected, the side surface 20c of the cover 20 and the side surface 30c of the main body 30 constitute the side surface 100c of the suction device 100.

[0241] like Figure 22 to Figure 24 As shown, the cover 20 is configured as an annular body having an opening 142 and a through hole 22 with openings 23 as both ends. A thread groove 21 capable of being screwed with a thread 31 provided on the main body 30 is provided on the lower side of the inner wall 22a of the through hole 22 of the cover 20. The main body 30 is configured as a bottomed cylindrical body having a bottomed hole 33 with an opening 34 and a bottom 143 as both ends. A cylindrical protrusion 32 extending along the bottomed hole 33 is provided at the center of the top surface 30a of the main body 30, and the protrusion 32 has an opening 34 on the top surface and a thread 31 on the outer peripheral surface. By rotating the cover 20 and the main body 30 in a state where the thread 31 is meshed with the thread groove 21, the cover 20 and the main body 30 can be connected or disconnected. In the suction device 100 in a state where the cover 20 and the main body 30 are connected, a gap 40 can be provided between the bottom surface 20b of the cover 20 and the top surface 30a of the main body 30.

[0242] like Fig.23 and Fig.24 As shown, the upper side of the inner wall 22a of the through hole 22 of the cover 20 (the portion where the thread groove 21 is not provided) constitutes a part of the upper side of the inner wall 145 of the receiving portion 140. On the other hand, the inner wall 33a of the bottomed hole 33 of the main body 30 constitutes a part of the lower side of the inner wall 145 of the receiving portion 140. And, in the state where the cover 20 is connected to the main body 30, the through hole 22 is connected to the bottomed hole 33 to constitute the receiving portion 140. In particular, the upper side of the inner wall 22a of the through hole 22 of the cover 20 and the inner wall 33a of the bottomed hole 33 of the main body 30 are connected to form a plane, constituting the inner wall 145 of the receiving portion 140.

[0243] Here, refer to Figure 6 to Figure 8The convex portion 145a and the concave portion 145b described above are preferably provided on both the upper side of the inner wall 22a of the through hole 22 of the cover 20 and the inner wall 33a of the bottomed hole 33 of the main body 30. Fig. 9 The flat surface 145 c and the curved surface 145 d described above are preferably provided on both the upper side of the inner wall 22 a of the through hole 22 of the cover 20 and the inner wall 33 a of the bottomed hole 33 of the body 30 .

[0244] like Figure 22 to Figure 24 As shown, a plurality of anti-skid members 35 are provided around the protrusion 32 in the top surface 30a of the main body 30. In the suction device 100 in the state where the cover 20 is connected to the main body 30, the anti-skid members 35 are in contact with the bottom surface 20b of the cover 20 to prevent the cover 20 from rotating. According to this structure, it is difficult to accidentally release the connection between the cover 20 and the main body 30. The structure of the anti-skid member 35 is not particularly limited, and for example, it can be composed of an elastic body such as rubber. In addition, the anti-skid member 35 can also be provided on the bottom surface 20b of the cover 20 together with the top surface 30a of the main body 30 or instead of it.

[0245] As mentioned above Fig.10 as well as Fig.11 As described above, the suction device 100 may also be provided with an air flow path 146. Fig.25 Provide explanation.

[0246] Fig.25 1 is a diagram schematically showing another example of a cross section of the suction device 100 in a state where the cover 20 and the main body 30 are connected in the first example of the attachment and detachment mechanism. Fig.25 As shown, a through hole 36 may be provided at the root portion of the protrusion 32 of the main body 30. In this case, when the cover 20 and the main body 30 are connected, the gap 40 generated between the bottom surface 20b of the cover 20 and the top surface 30a of the main body 30 and the through hole 36 constitute an air flow path 146. In this case, an air flow 190 is generated in a manner passing through the air flow path 146 along with suction.

[0247] (2) Second Example

[0248] Fig.26 This is a diagram for explaining a second example of the attachment and detachment mechanism of the suction device 100 according to the present modification. Fig. 27 This is a diagram schematically showing an example of a cross section of the suction device 100 in a state where the connection between the cover 20 and the main body 30 is released in the second example of the attachment and detachment mechanism. Fig.28 1 is a diagram schematically showing an example of a cross section of the suction device 100 in a state where the cover 20 and the main body 30 are connected in the second example of the attachment and detachment mechanism. Fig. 27 as well as Fig.28, an example of a cross section of the suction device 100 cut along the vertical direction in a manner passing through the center of the receiving portion 140 is schematically shown. Figure 26 to Figure 28 As shown, the cover 20 and the main body 30 are connected in a manner that the bottom surface 20b of the cover 20 overlaps the top surface 30a of the main body 30. The top surface 20a of the cover 20 constitutes the top surface 100a of the suction device 100. The bottom surface 30b of the main body 30 constitutes the bottom surface 100b of the suction device 100. When the cover 20 and the main body 30 are connected, the side surface 20c of the cover 20 and the side surface 30c of the main body 30 constitute the side surface 100c of the suction device 100.

[0249] like Figure 26 to Figure 28 As shown, the cover 20 is a bottomed cylindrical body having a receiving portion 140. The cover 20 has a head 24 constituting the upper side of the cover 20 and a protrusion 25 configured to be thinner than the head 24 and protruding downward from the head 24. The main body 30 has a bottomed hole 37 capable of receiving the protrusion 25 of the cover 20. Fig. 27 and Fig.28 As shown, the cover 20 can be connected to the main body 30 by inserting the protrusion 25 of the cover 20 into the bottomed hole 37 of the main body 30. In addition, the connection between the cover 20 and the main body 30 can be released by pulling the protrusion 25 of the cover 20 out of the bottomed hole 37 of the main body 30. The receiving portion 140 can be removed from the main body 30 storing electronic components such as the power supply unit 111, so the receiving portion 140 can be easily washed with water, which can improve the maintainability. In the suction device 100 in the state where the cover 20 is connected to the main body 30, a gap 40 can be provided between the bottom surface 20b of the cover 20 (more specifically, the head 24 of the cover 20) and the top surface 30a of the main body 30.

[0250] like Fig. 27 and Fig.28 As shown in FIG. 1 , the inner diameter of the bottomed hole 37 is preferably the same or substantially the same as the outer diameter of the protrusion 25 of the cover 20. In this case, when the cover 20 and the main body 30 are connected, the protrusion 25 of the cover 20 and the bottomed hole 37 of the main body 30 are closely attached without a gap, so that the cover 20 and the main body 30 can be firmly connected. Fig. 27 as well as Fig.28 As shown, the outer diameter of the head 24 of the cap 20 is preferably the same as the outer diameter of the main body 30. In this case, when the cap 20 and the main body 30 are connected, the unevenness of the side surface 20c of the cap 20 and the side surface 30c of the main body 30 can be reduced, and the side surface 100c of the suction device 100 can be smoothly formed.

[0251] As mentioned above Fig.10 as well as Fig.11 As described above, the suction device 100 may also be provided with an air flow path 146. Fig.29 Provide explanation.

[0252] Fig.29 1 is a diagram schematically showing another example of a cross section of the suction device 100 in a state where the cover 20 and the main body 30 are connected in the second example of the attachment and detachment mechanism. Fig.29 As shown, the through hole 26 may be provided at the base portion of the protrusion 25 of the cover 20. In this case, when the cover 20 and the main body 30 are connected, the gap 40 generated between the bottom surface 20b of the cover 20 and the top surface 30a of the main body 30 and the through hole 26 can constitute the air flow path 146. In this case, the air flow 190 is generated in a manner passing through the air flow path 146 along with suction.

[0253] (3) Control corresponding to attachment and detachment of the cover 20 and the main body 30

[0254] The connection and release of the cover 20 and the main body 30 can be determined by any method. For example, the cover 20 may also have a magnetic part that generates a magnetic field. Moreover, the main body 30 may also have a magnetic sensor that detects the magnetic field. An example of a magnetic part is a magnet, and an example of a magnetic sensor is a Hall sensor. Moreover, the control unit 116 determines whether the cover 20 and the main body 30 are connected based on the detection result of the magnetic sensor. For example, the control unit 116 determines that the cover 20 and the main body 30 are connected when the intensity of the magnetic field detected by the magnetic sensor is above a threshold value, and determines that the connection between the cover 20 and the main body 30 is released when this is not the case. According to this configuration, the connection and release of the cover 20 and the main body 30 can be easily determined.

[0255] The suction device 100 may also be set based on whether the cover 20 and the main body 30 are connected. As an example, the control unit 116 may also set whether heating by the heating unit 121 is possible based on whether the cover 20 and the main body 30 are connected. That is, the control unit 116 may also allow heating by the heating unit 121 when the cover 20 and the main body 30 are connected. When a user operation indicating the start of heating is performed in a state where heating is allowed, the control unit 116 starts supplying power to the heating unit 121. On the other hand, the control unit 116 may also prohibit heating by the heating unit 121 when the connection between the cover 20 and the main body 30 is released. In a state where heating is prohibited, even if a user operation indicating the start of heating is performed, the control unit 116 does not start supplying power to the heating unit 121. In a state where the cover 20 is removed from the main body 30, the heat insulation of the suction device 100 may be reduced. In this regard, according to this configuration, safety can be improved. The type of the cover 20 connected to the main body 30 can be identified by any method. For example, the control unit 116 may also determine the type of the cover 20 connected to the main body 30 based on the detection result of the magnetic sensor. As an example, the cover 20 may also have a magnetic portion that generates different magnetic fields depending on the type of the cover 20. Specifically, the cover 20 may also have a magnetic portion that generates magnetic fields of different strengths depending on the type of the cover 20. In this case, the control unit 116 may also determine that a first type of cover 20 is connected to the main body 30 when the strength of the magnetic field detected by the magnetic sensor is greater than the first threshold and less than the second threshold. On the other hand, the control unit 116 may also determine that a second type of cover 20 is connected to the main body 30 when the strength of the magnetic field detected by the magnetic sensor is greater than the second threshold and less than the third threshold. According to this configuration, the type of the cover 20 connected to the main body 30 can be easily determined.

[0256] The suction device 100 may also perform settings based on the type of the cap 20 connected to the main body 30. As an example, the control unit 116 may also set a heating curve used in heating the rod-shaped substrate 150 based on the type of the cap 20 connected to the main body 30. Specifically, the control unit 116 may also set a first heating curve to be used when a first type of cap 20 is connected to the main body 30. In addition, the control unit 116 may also set a second heating curve to be used when a second type of cap 20 is connected to the main body 30. The first heating curve is a heating curve different from the second heating curve. As another example, the control unit 116 may also set a notification method of the notification unit 113 based on the type of the cap 20 connected to the main body 30. Specifically, the control unit 116 may also set a first light emission mode as the light emission mode of the LED 12 and / or the LED 92 when the first type of cap 20 is connected to the main body 30. In addition, the control unit 116 may also set a second light emission mode as the light emission mode of the LED 12 and / or the LED 92 when the second type of cap 20 is connected to the main body 30. The second light emission pattern is a light emission pattern different from the first light emission pattern. According to this configuration, the use comfort of the suction device 100 can be easily customized.

[0257] In addition, the cover 20 may also have a storage medium for storing setting information of the suction device 100. An example of the setting information is a heating curve. Another example of the setting information is a notification method of the notification unit 113. On the other hand, the main body 30 may also have a reading unit that reads information from the storage medium of the cover 20 installed on the main body 30. An example of the storage medium is an RFID (radiofrequency identifier) ​​RF tag, and an example of the reading unit is a wireless reader. Moreover, the control unit 116 may also perform settings based on the setting information read from the storage medium of the cover 20 connected to the main body 30.

[0258] <2.2. Second Modification>

[0259] Fig.30 1 is a diagram for explaining the outline of the aerosol generating system 1 according to this modification. Fig.30 , an example of a state in which the connection between the suction device 100 and the charging device 900 of the present modification is released is shown.

[0260] (1) Regarding the button 11 and the LED 12

[0261] like Fig.30As shown, the suction device 100 is provided with a button 11-1 and a button 11-2. The button 11-1 is an example of a first operating unit capable of accepting user operations for the aerosol generating system 1. The button 11-2 is an example of a second operating unit capable of accepting user operations for the aerosol generating system 1 and different from the first operating unit.

[0262] The control unit 116 may also control the operation of the heating unit 121 based on the heating curve corresponding to the button 11-1 when the button 11-1 is pressed. For example, the storage unit 114 stores a first heating curve as a heating curve to be used when the button 11-1 is pressed. In this case, the control unit 116 controls the operation of the heating unit 121 based on the first heating curve when the button 11-1 is pressed. On the other hand, the control unit 116 may also control the operation of the heating unit 121 based on the heating curve corresponding to the button 11-2 when the button 11-2 is pressed. For example, the storage unit 114 stores a second heating curve as a heating curve to be used when the button 11-2 is pressed. In this case, the control unit 116 controls the operation of the heating unit 121 based on the second heating curve when the button 11-2 is pressed. According to this configuration, the user can use a favorite heating curve by pressing the button 11-1 or the button 11-2.

[0263] Here, the suction device 100 may also switch the heating curve used during the execution of heating based on the heating curve. However, when the heating curve used is switched, the control unit 116 continues to use the heating time before the switch, and controls the operation of the heating unit 121 from the middle with reference to the heating curve after the switch. In detail, when the control unit 116 presses the button 11-2 in the middle of controlling the operation of the heating unit 121 based on the heating curve corresponding to the button 11-1, the control unit 116 controls the operation of the heating unit 121 from the middle with reference to the heating curve corresponding to the button 11-2. For example, with the pressing of the button 11-1 as a trigger, the button 11-2 is pressed when 120 seconds have passed since the start of heating based on the first heating curve. In this case, the control unit 116 controls the operation of the heating unit 121 based on the time series transition of the target temperature after 120 seconds from the start of heating in the second heating curve. Similarly, when the button 11-1 is pressed in the middle of controlling the operation of the heating unit 121 based on the heating curve corresponding to the button 11-2, the control unit 116 controls the operation of the heating unit 121 with reference to the heating curve corresponding to the button 11-1 from the middle. For example, the button 11-1 is pressed when 120 seconds have passed since the start of heating based on the second heating curve, triggered by the pressing of the button 11-2. In this case, the control unit 116 controls the operation of the heating unit 121 based on the time series transition of the target temperature after 120 seconds have passed since the start of heating in the first heating curve. According to this configuration, the switching of the heating curve in the middle of the heating period can be smoothly implemented.

[0264] like Fig.30 As shown, LED 12-1 and LED 12-2 are configured in the suction device 100. LED 12-1 and LED 12-2 are examples of notification units that output information notified from the aerosol generating system 1 to the user. In particular, LED 12-1 is an example of a first notification unit configured to correspond to the button 11-1. Specifically, LED 12-1 is configured to surround the button 11-1. LED 12-2 is an example of a second notification unit configured to correspond to the button 11-2. Specifically, LED 12-2 is configured to surround the button 11-2.

[0265] LED12-1 may also notify information related to the processing executed by triggering the pressing of button 11-1. As an example, LED12-1 may also notify information indicating the progress of heating based on the heating curve corresponding to button 11-1. In detail, the control unit 116 may also control the action of the heating unit 121 based on the first heating curve when button 11-1 is pressed, and notify information indicating the progress of heating based on the first heating curve through LED12-1. Similarly, LED12-2 may also notify information related to the processing executed by triggering the pressing of button 11-2. As an example, LED12-2 may also notify information indicating the progress of heating based on the heating curve corresponding to button 11-2. In detail, the control unit 116 may also control the action of the heating unit 121 based on the second heating curve when button 11-2 is pressed, and notify information indicating the progress of heating based on the second heating curve through LED12-2. According to this configuration, the relationship between user operation and notification can be more easily understood. LED12-1 and LED12-2 may also notify information indicating the charging state of the suction device 100. In particular, LED12-1 may also notify information indicating the remaining number of heating times when the heating curve corresponding to the button 11-1 is used. For example, when the heating curve corresponding to the button 11-2 is the first heating curve, the remaining number of heating times when the heating curve corresponding to the button 11-1 is used is the number of times heating based on the first heating curve can be performed using the power accumulated in the power supply unit 111. On the other hand, LED12-2 may also notify information indicating the remaining number of heating times when the heating curve corresponding to the button 11-2 is used. For example, when the heating curve corresponding to the button 11-2 is the second heating curve, the remaining number of heating times when the heating curve corresponding to the button 11-2 is used is the number of times heating based on the second heating curve can be performed using the power accumulated in the power supply unit 111. In the heating curve corresponding to the button 11-1 and the heating curve corresponding to the button 11-2, the power consumed during heating is sometimes different. For example, as Fig.13 The first heating curve shown in FIG. 1 is similar to the high temperature type heating curve shown in FIG. Fig.15 Compared with a low-temperature type heating curve such as the second heating curve shown in FIG. 1 , the power consumed during heating is larger. Therefore, the remaining number of heating times when the first heating curve is used may be less than the remaining number of heating times when the second heating curve is used. According to this configuration, the remaining number of heating times that differs according to the heating curve used can be notified for each heating curve. Therefore, a heating curve with a large number of remaining heating times can be selected, and usability related to the selection of the heating curve used can be improved.

[0266] In addition, the notification of the remaining number of heating times when the heating curve corresponding to button 11-1 is used and the notification of the remaining number of heating times when the heating curve corresponding to button 11-2 is used may also be performed at different timings. For example, LED 12-1 may also notify the remaining number of heating times when the heating curve corresponding to button 11-1 is used when button 11-1 is pressed. In addition, LED 12-2 may also notify the remaining number of heating times when the heating curve corresponding to button 11-2 is used when button 11-2 is pressed.

[0267] Of course, the notification of the remaining number of heating times when the heating curve corresponding to the button 11-1 is used and the notification of the remaining number of heating times when the heating curve corresponding to the button 11-2 is used may be executed simultaneously. For example, the power off, power on, sleep, or recovery from sleep of the suction device 100 may be used as a trigger to execute these notifications simultaneously.

[0268] As described in the first modification, in this modification, the cap 20 and the main body 30 may be configured to be detachable. Furthermore, the suction device 100 may be set based on the type of the cap 20 connected to the main body 30.

[0269] As an example, the suction device 100 may also set a heating curve used in heating the rod-type substrate 150 based on the type of the cover 20 connected to the main body 30. In detail, the control unit 116 may also set at least one of the heating curve corresponding to the button 11-1 and the heating curve corresponding to the button 11-2 according to the type of the cover 20 connected to the main body 30. For example, the control unit 116 may also establish a correspondence between the first heating curve and the button 11-1 and the second heating curve and the button 11-2 when a first type of cover 20 is connected to the main body 30. In addition, the control unit 116 may also establish a correspondence between the second heating curve and the button 11-1 and the first heating curve and the button 11-2 when a second type of cover 20 is connected to the main body 30. According to this configuration, the use comfort of the suction device 100 can be easily customized.

[0270] As another example, the suction device 100 may also set the notification method of the notification unit 113 based on the type of cover 20 connected to the main body 30. In detail, the control unit 116 may also set the notification method based on at least one of LED12-1 and LED12-2 based on the type of cover 20 connected to the main body 30. For example, when a first type of cover 20 is connected to the main body 30, the control unit 116 may also set the first light emission mode as the light emission mode of LED12-1, and set the second light emission mode as the light emission mode of LED12-2. In addition, when a second type of cover 20 is connected to the main body 30, the control unit 116 may also set the second light emission mode as the light emission mode of LED12-1, and set the first light emission mode as the light emission mode of LED12-2. According to this configuration, the use comfort of the suction device 100 can be easily customized. Next, referring to Fig.31 , which illustrates an example of the process flow of the processing performed in this variant. Fig.31 1 is a flowchart showing an example of the flow of processing executed by the suction device 100 of this modification. In the following, it is assumed that the first heating curve is associated with the button 11 - 1 and the second heating curve is associated with the button 11 - 2 .

[0271] like Fig.31 As shown, first, the sensor unit 112 detects the pressing of the button 11 - 1 corresponding to the first heating curve or the button 11 - 2 corresponding to the second heating curve (step S202 ).

[0272] Next, the control unit 116 starts heating based on the heating curve corresponding to the pressed button 11 (step S204). As an example, the control unit 116 starts controlling the operation of the heating unit 121 based on the first heating curve when the button 11-1 is pressed. As another example, the control unit 116 starts controlling the operation of the heating unit 121 based on the second heating curve when the button 11-2 is pressed.

[0273] Next, the control unit 116 notifies information indicating the progress of heating through the LED 12 corresponding to the button 11 corresponding to the heating curve in use (step S206). As an example, when the first heating curve is in use, the LED 12-1 corresponding to the button 11-1 corresponding to the first heating curve notifies information indicating the progress of heating based on the first heating curve. As another example, when the second heating curve is in use, the LED 12-2 corresponding to the button 11-2 corresponding to the second heating curve notifies information indicating the progress of heating based on the second heating curve.

[0274] Next, the control unit 116 determines whether the button 11 corresponding to the heating curve different from the heating curve in use is pressed (step S208). As an example, the control unit 116 determines whether the button 11-2 is pressed during heating based on the first heating curve. As another example, the control unit 116 determines whether the button 11-1 is pressed during heating based on the second heating curve.

[0275] When it is determined that the button 11 corresponding to the heating curve different from the heating curve in use is pressed (step S208: Yes), the control unit 116 switches the heating curve in use and continues heating (step S210). For example, when the heating curve is switched when 120 seconds have passed since the start of heating, the control unit 116 controls the operation of the heating unit 121 based on the time series transition of the target temperature after 120 seconds have passed since the start of heating in the switched heating curve. Thereafter, the process proceeds to step S212. When it is determined that the button 11 corresponding to the heating curve different from the heating curve in use is not pressed (step S208: No), the process also proceeds to step S212.

[0276] In step S212, the control unit 116 determines whether the end condition is satisfied (step S212). An example of the end condition is that heating is performed to the end of the heating period. Another example of the end condition is that the number of puffs reaches a prescribed number of times. If it is determined that the end condition is not satisfied (step S212: No), the process returns to step S206.

[0277] When it is determined that the end condition is satisfied (step S212 : Yes), the control unit 116 ends the heating (step S214 ).

[0278] (2) Regarding button 91 and LED 92

[0279] Refer again Fig.30 The charging device 900 includes a button 91-1 and a button 91-2. The button 91-1 is an example of a first operating unit capable of accepting user operations for the aerosol generating system 1. The button 91-2 is an example of a second operating unit capable of accepting user operations for the aerosol generating system 1 and different from the first operating unit.

[0280] Refer again Fig.30, LED92-2 and LED92-2 are configured in the charging device 900. LED92-1 and LED92-2 are examples of notification units that output information notified from the aerosol generating system 1 to the user. In particular, LED92-1 is an example of a first notification unit configured to correspond to the button 91-1. Specifically, LED92-1 is configured to surround the button 91-1. LED92-2 is an example of a second notification unit configured to correspond to the button 91-2. Specifically, LED92-2 is configured to surround the button 91-2.

[0281] The features described above with respect to button 11-1 and button 11-2 may also be possessed by button 91-1 and button 91-2. In addition, the features described above with respect to LED 12-1 may also be possessed by LED 92-1 and LED 92-2. That is, in the above description with respect to button 11-1, button 11-2, LED 12-1, and LED 12-2, button 11-1 may be replaced by button 91-1, button 11-2 may be replaced by button 91-2, LED 12-1 may be replaced by LED 92-1, and LED 12-2 may be replaced by LED 92-2.

[0282] (3) Supplement

[0283] The first operating unit and the second operating unit may be disposed in either the suction device 100 or the charging device 900. In the above-described examples, the first operating unit and the second operating unit are both disposed in the suction device 100 and the charging device 900, but the present disclosure is not limited to such examples.

[0284] Alternatively, one of the first operating unit and the second operating unit may be disposed in the suction device 100, and the charging device 900 may be disposed in the other. For example, a button 11 may be disposed in the suction device 100 as the first operating unit. Alternatively, a LED 12 may be disposed in the suction device 100 as the first notification unit. Furthermore, a button 91 may be disposed in the charging device 900 as the second operating unit. Alternatively, a LED 92 may be disposed in the charging device 900 as the second notification unit. In this case, when the button 11 is pressed, the suction device 100 heats the rod-shaped substrate 150 based on the first heating curve, and notifies the information indicating the progress of heating through the LED 12. On the other hand, when the button 91 is pressed, the suction device 100 heats the rod-shaped substrate 150 based on the second heating curve, and notifies the information indicating the progress of heating through the LED 92.

[0285] In the above description, an example is described in which two buttons 11 and two LEDs 12 are arranged in the suction device 100, but the present disclosure is not limited to this example. Three or more buttons 11 and three or more LEDs 12 may be arranged in each. The same is true for the buttons 91 and LEDs 92 arranged in the charging device 900.

[0286] <2.3. Third Modification>

[0287] Fig.32 Schematic diagram schematically showing an example of the structure of the suction device 100 of this modified example. Fig.32 As shown, the suction device 100 of this modified example may also have two heating parts 121, namely, heating part 121-1 and heating part 121-2. The side of the receiving part 140 close to the bottom 143 is also called upstream, and the side close to the opening 142 is also called downstream. This is because when suction is performed, an air flow from the upstream to the downstream is generated. Fig.32 As shown, the heating unit 121-1 is arranged on the upstream side. In addition, the heating unit 121-2 is arranged on the downstream side. The control unit 116 can also control the operation of the heating unit 121-1 and the heating unit 121-2 based on different heating curves. Fig.33 An example of a heating curve for controlling the operation of the heating unit 121 - 1 and the heating unit 121 - 2 will be described.

[0288] Fig.33 Graph 80 is a graph schematically showing an example of a heating curve of the present variation. The horizontal axis of graph 80 is time. The vertical axis of graph 80 is temperature. Line 81 represents the time series transition of the target temperature specified by the heating curve used in controlling the operation of heating unit 121-1. The heating curve shown by line 81 is also referred to as the third heating curve. Line 82 represents the time series transition of the target temperature specified by the heating curve used in controlling the operation of heating unit 121-2. The heating curve shown by line 82 is also referred to as the fourth heating curve. The control unit 116 may control the operation of the heating unit 121-1 based on the third heating curve, and control the operation of the heating unit 121-2 based on the fourth heating curve.

[0289] As shown by lines 81 and 82, the heating section 121-2 arranged on the downstream side becomes high temperature first, and then, after some delay, the heating section 121-1 arranged on the upstream side becomes high temperature. According to this structure, the aerosol source is heated in sequence from the downstream side to the upstream side of the substrate portion 151 to generate aerosol. Assuming that the upstream side of the substrate portion 151 is heated earlier than the downstream side, the aerosol generated on the upstream side may be cooled and condensed when passing through the downstream side. In this case, the downstream side of the substrate portion 151 that has not been heated becomes wet, and the aroma tasted by the user may deteriorate when the downstream side of the substrate portion 151 is heated. In this regard, according to this structure, the generated aerosol will not pass through the unheated portion of the substrate portion 151. As a result, it is possible to prevent the unheated portion of the substrate portion 151 from becoming wet, and thus it is possible to prevent the deterioration of the aroma tasted by the user.

[0290] As described in the above embodiment, the suction device 100 may also switch the heating curve used when heating the rod-shaped substrate 150. As an example, the suction device 100 may select a heating curve used to control the operation of the heating unit 121-1 from the third heating curve or the fifth heating curve. In addition, the suction device 100 may select a heating curve used to control the operation of the heating unit 121-2 from the fourth heating curve or the sixth heating curve. Fig.34 An example of the fifth heating curve and the sixth heating curve will be described.

[0291] Fig.34 83 is a graph schematically showing an example of a heating curve of this modification. The horizontal axis of the graph 83 is time. The vertical axis of the graph 83 is temperature. Line 84 represents the time series transition of the target temperature specified by the fifth heating curve that can be used to control the operation of the heating unit 121-1. Line 85 represents the time series transition of the target temperature specified by the sixth heating curve that can be used to control the operation of the heating unit 121-2. The control unit 116 can also control the operation of the heating unit 121-1 based on the fifth heating curve and control the operation of the heating unit 121-2 based on the sixth heating curve.

[0292] Reference Fig.33 as well as Fig.34 When the fifth and sixth heating curves are used, as in the case of the third and fourth heating curves, the heating unit 121-2 disposed on the downstream side first reaches a high temperature, and then, after a delay, the heating unit 121-1 disposed on the upstream side reaches a high temperature. According to this configuration, it is possible to prevent the flavor that the user enjoys from being deteriorated. Moreover, if referring to Fig.33 as well as Fig.34, it can be said that the third heating curve and the fourth heating curve are high-temperature heating curves, and the fifth and sixth heating curves are low-temperature heating curves. For example, in the third heating curve, the target temperature reaches a maximum of 265°C, while in the fifth heating curve, the target temperature reaches a maximum of 255°C. In addition, in the fourth heating curve, the target temperature reaches 260°C 10 seconds after the start of heating, while in the sixth heating curve, the target temperature reaches 250°C 210 seconds after the start of heating. In this way, it is possible to switch between the high-temperature heating curve and the low-temperature heating curve, so that the user can enjoy the suction feeling corresponding to the mood.

[0293] As described in the above embodiment, the suction device 100 may also switch the heating curve used during the execution of heating based on the heating curve. As an example, the suction device 100 may also switch the heating curve used to the fifth and sixth heating curves during the execution of heating based on the third and fourth heating curves. Of course, the opposite may also be true. In addition, as described in the above embodiment, when the heating curve used is switched, the control unit 116 uses the heating time before the switching and controls the operation of the heating unit 121-1 and the heating unit 121-2 by referring to the heating curve after the switching from the middle.

[0294] <2.4. Fourth Modification>

[0295] As reference Figure 4 As mentioned above, the means for atomizing the aerosol source is not limited to the heating by the heating unit 121. For example, the means for atomizing the aerosol source may also be induction heating. Fig.35 An example of the configuration of the suction device 100 that performs induction heating will be described.

[0296] Fig.35 Schematic diagram schematically showing a configuration example of the suction device of this modification. Fig.35 As shown, the suction device 100 of this configuration example includes a power supply unit 111 , a sensor unit 112 , a notification unit 113 , a storage unit 114 , a communication unit 115 , a control unit 116 , a storage unit 140 , and an electromagnetic induction source 162 .

[0297] The configurations of the power supply unit 111, the sensor unit 112, the notification unit 113, the storage unit 114, the communication unit 115, and the control unit 116 are shown in FIG. Figure 4 The configuration described above is substantially the same. However, the power supply unit 111 may supply a direct current to other components. In addition, the power supply unit 111 may supply an alternating current converted by an inverter circuit to other components.

[0298] As mentioned above Figure 4As described above, the rod-type substrate 150 includes a substrate portion 151 and a mouthpiece portion 152. Furthermore, the rod-type substrate 150 includes a heat-sensitive body 161. The heat-sensitive body 161 generates heat by electromagnetic induction. The heat-sensitive body 161 is made of a conductive material such as metal. Furthermore, the heat-sensitive body 161 preferably has magnetism. As an example, the heat-sensitive body 161 can be configured as a metal plate or a metal rod. The heat-sensitive body 161 is arranged in thermal proximity to the aerosol source. That is, the heat-sensitive body 161 is arranged at a position where the heat generated by the heat-sensitive body 161 is transferred to the aerosol source. Fig.35 In the example shown, the heat-sensitive body 161 is included in the base portion 151 of the rod-shaped base 150. In addition, the heat-sensitive body 161 may not be accessible from the outside of the rod-shaped base 150. For example, the heat-sensitive body 161 may be distributed in the center of the rod-shaped base 150 instead of being distributed near the periphery.

[0299] The electromagnetic induction source 162 inductively heats the heat-sensitive body 161. When an alternating current is applied to the electromagnetic induction source 162, a variable magnetic field (more specifically, an alternating magnetic field) is generated. The electromagnetic induction source 162 is arranged at a position where the generated variable magnetic field overlaps with the internal space of the receiving section 140, and more specifically, overlaps with the heat-sensitive body 161 of the rod-shaped substrate 150 received in the receiving section 140. For example, the electromagnetic induction source 162 is composed of a coil-shaped conductive wire, and is arranged in a manner wound around the outer periphery of the receiving section 140. Thus, when a variable magnetic field is generated in a state where the rod-shaped substrate 150 is received in the receiving section 140, the variable magnetic field generated from the electromagnetic induction source 162 invades the heat-sensitive body 161 located in the internal space 141 of the receiving section 140, and the heat-sensitive body 161 is inductively heated. Specifically, eddy current loss is generated in the heat-sensitive body 161, and when the heat-sensitive body 161 has magnetism, hysteresis loss is further generated in the heat-sensitive body 161, and the temperature of the heat-sensitive body 161 rises. Then, the aerosol source included in the rod-shaped substrate 150 is heated and atomized by the inductively heated heat-sensitive body 161, thereby generating an aerosol. As an example, when the sensor unit 112 detects that the user has started suction and / or inputs predetermined information, power may be supplied to the electromagnetic induction source 162. Furthermore, when the sensor unit 112 detects that the user has finished suction and / or inputs predetermined information, power supply to the electromagnetic induction source 162 may be stopped.

[0300] The above is a description of a configuration example of the suction device 100. Of course, the configuration of the suction device 100 is not limited to the above, and various configurations as exemplified below can be adopted.

[0301] The heat-sensitive body 161 may be provided in the suction device 100 instead of being included in the rod-shaped substrate 150. As an example, the suction device 100 may also include a heat-sensitive body 161 disposed on the outside of the internal space 141. Specifically, the housing portion 140 may also be composed of a material having conductivity and magnetism, and function as the heat-sensitive body 161. The housing portion 140 as the heat-sensitive body 161 is in contact with the outer periphery of the substrate portion 151, and thus can be thermally close to the aerosol source contained in the substrate portion 151. As another example, the suction device 100 may also include a heat-sensitive body 161 disposed on the inside of the internal space 141. Specifically, the heat-sensitive body 161 configured in a plate shape may also be configured in a manner protruding from the bottom 143 of the housing portion 140 to the internal space 141. When the rod-shaped substrate 150 is inserted into the internal space 141 of the storage portion 140, the sheet-shaped heat-sensitive body 161 is inserted into the rod-shaped substrate 150 in a manner of piercing the substrate portion 151 of the rod-shaped substrate 150. Thus, the sheet-shaped heat-sensitive body 161 can be thermally close to the aerosol source contained in the substrate portion 151. In the case where the rod-shaped substrate 150 has the electromagnetic induction source 162, the insertion of the rod-shaped substrate 150 can also be detected based on the characteristic change of the circuit in the suction device 100 caused by the insertion of the rod-shaped substrate 150. An example of the characteristic change of the circuit in the suction device 100 is the change of inductance generated by the electromagnetic induction source 162.

[0302] In this modification, the cover 20 is preferably made of a material that is not conductive and magnetic. Examples of such a material include glass, rubber, and plastic. According to this configuration, the cover 20 is less likely to be inductively heated, thereby ensuring the safety of the user.

[0303] The electromagnetic induction source 162 of this modification corresponds to the heating unit 121 described in the above embodiment. The temperature of the heating aerosol source in this modification corresponds to the temperature of the heat-sensitive body 161. The temperature of the heat-sensitive body 161 can be estimated based on the resistance value of the electromagnetic induction source. In the modification, the parameter related to the temperature of the heating aerosol source specified by the heating curve is the target value (i.e., target temperature) of the temperature of the heat-sensitive body 161. The control unit 116 controls the operation of the electromagnetic induction source 162 so that the temperature of the heat-sensitive body 161 changes in the same manner as the target temperature specified in the heating curve.

[0304] <2.5. Fifth Modification>

[0305] Fig.36 1 is a diagram for explaining the outline of the aerosol generating system 1 according to this modification. Fig.36 As shown, the aerosol generating system 1 of this modified example has the same Figure 1However, in this modification, the cover 20 can be rotated clockwise or counterclockwise, and the shutter 147 operates according to the rotation of the cover 20. Fig.36 As shown on the left side of FIG. 1 , when the cover 20 is rotated counterclockwise, as shown in FIG. Fig.36 As shown on the right side of the cover 20, the shutter 147 closes the opening 142. On the other hand, when the cover 20 is rotated clockwise, the shutter 147 opens the opening 142. In this way, the shutter 147 can also open and close the opening 142 according to the rotation of the cover 20. The control unit 116 can also control the operation of the suction device 100 according to the state of the shutter 147. As an example, the control unit 116 can also prohibit the heating of the heating unit 121 when the shutter 147 closes the opening 142. On the other hand, the control unit 116 can also allow the heating of the heating unit 121 when the shutter 147 opens the opening 142. If it is considered that the rod-shaped substrate 150 can be inserted when the shutter 147 opens the opening 142, this configuration can prevent the so-called dry burning.

[0306] In this modification, the cover 20 and the main body 30 may be detachable or integrally formed. In addition, the suction device 100 and the charging device 900 may be detachable or integrally formed.
