Summary of the Invention

Problems to be Solved by the Invention

[0004] In the device described in Patent Document 1, the rod-shaped smoking material is heated while being inserted into the device. And when the smoking material is, for example, shredded tobacco as an aerosol source wrapped in paper and formed into a rod shape, and the tip of the rod-shaped part has shredded tobacco exposed, after being sucked, a part of the heated shredded tobacco separated from the main body (hereinafter sometimes referred to as "shreds such as tobacco leaves") remains in the device. For device maintenance, it is necessary to remove shreds such as tobacco leaves. Therefore, if there are a lot of shreds such as tobacco leaves, it will take a lot of labor for device maintenance. On the other hand, since the aerosol source is heated by the heat generated in the component that heats the aerosol source (a susceptor in Patent Document 1), it is conceivable to detect the temperature of the component that heats the aerosol source and control the heating of this component based on the detected temperature in order to set the temperature of the aerosol source to an appropriate temperature. For this purpose, it is desirable to detect the temperature of the component that heats the aerosol source with high accuracy. The present invention provides a suction device that can reduce the maintenance effort required for the device and can accurately detect the temperature of the component that heats the aerosol source. [Means for solving the problem]

A fourth feature is that the device further comprises a substrate to which the ends of the lead wires are connected, and the lead wires may be brought out to the outside of the electromagnetic induction source at a position closer to the substrate than the electromagnetic induction source in the direction of the center line. The fifth feature is a suction device comprising: an electromagnetic induction source positioned in an insertion section into which a cylindrical container having a bottom and filled with an aerosol source is inserted, and which heats the container by induction heating; an opening / closing member that transitions between a state of covering the opening of the insertion section and a state of leaving the opening open, and which has an outlet formed for the aerosol generated by heating the aerosol source when it is in the covering state; and a temperature sensor attached to the opening / closing member for detecting the temperature of the container.

[Modes for carrying out the invention]

[0008] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. <First Embodiment> FIG. 1 is a perspective view showing an example of a state in which components constituting the suction device 1 according to the first embodiment are disassembled. FIG. 2 is an example of a cross-sectional view showing a schematic configuration of the suction device 1 according to the first embodiment. FIG. 3 is a diagram schematically showing an example of the schematic configuration of the suction device 1 according to the first embodiment. The suction device 1 according to the first embodiment is a device that generates a substance to be suctioned by a user. Hereinafter, it will be described assuming that the substance generated by the suction device 1 is an aerosol. Alternatively, the substance generated by the suction device 1 may be a gas.

[0009] The suction device 1 generates an aerosol by heating a base material 100 containing an aerosol source by induction heating (IH (Induction Heating)). The suction device 1 includes a power supply unit 10, an electromagnetic induction source 50, a support member 60 that supports the base material 100, and a temperature sensor 70 that detects the temperature of the base material 100. The suction device 1 also includes a cover 75 that covers the outer peripheries of the power supply unit 10, the electromagnetic induction source 50, the support member 60, etc., a mouthpiece 90, and an end cap 80 that houses a part of the mouthpiece 90. In the suction device 1, suction by the user is performed while the base material 100 is supported by the support member 60.

[0010] The cover 75 is formed in a cylindrical shape. The power supply unit 10, the electromagnetic induction source 50, and the mouthpiece 90 are arranged side by side in the direction of the central axis CL of the cylinder. In the following description, the direction of the central axis CL may be referred to as the "central axis direction". Also, the side on which the power supply unit 10 is arranged in the central axis direction may be referred to as the "first side", and the side of the mouthpiece 90 may be referred to as the "second side". Further, when viewed in the central axis direction, the direction intersecting the central axis CL may be referred to as the "radial direction", and the direction orbiting around the central axis CL may be referred to as the "circumferential direction".

[0011] (Power supply unit 10) As shown in FIG. 3, the power supply unit 10 includes a power supply section 11, a sensor section 12, a notification section 13, a memory section 14, a communication section 15, a control section 16, and an operation section 17 that can be operated by a user.

[0012] The power supply section 11 accumulates electric power. Then, the power supply section 11 supplies electric power to each component of the suction device 1. The power supply section 11 may be constituted by, for example, a rechargeable battery such as a lithium-ion secondary battery. The power supply section 11 may be charged by being connected to an external power supply via a USB (Universal Serial Bus) cable or the like. Also, the power supply section 11 may be charged in a state of being non-connected to a power transmission device on the power transmission side by wireless power transmission technology. Additionally, it may be possible to remove only the power supply section 11 from the suction device 1, and it may be possible to replace it with a new power supply section 11.

[0013] The sensor section 12 detects various information regarding the suction device 1. As an example, the sensor section 12 has a pressure sensor 12p such as a microphone condenser. Then, the sensor section 12 outputs the detected information to the control section 16. For example, when the pressure sensor 12p detects a numerical value associated with suction by the user, the sensor section 12 outputs information indicating that suction by the user has been performed to the control section 16.

[0014] The notification section 13 notifies the user of information. As an example, the notification section 13 is constituted by a light emitting device such as an LED (Light Emitting Diode). In that case, when the state of the power supply section 11 requires charging, when the power supply section 11 is being charged, and when an abnormality occurs in the suction device 1, etc., the notification section 13 emits light in different light emission patterns. The light emission pattern here is a concept including color, lighting / extinguishing timing, etc. The notification section 13 may be constituted by a display device that displays an image, a sound output device that outputs sound, a vibration device that vibrates, etc., together with or instead of the light emitting device.

[0015] The memory unit 14 stores various information for the operation of the suction device 1. The memory unit 14 is composed of a non-volatile storage medium such as flash memory. An example of the information stored in the memory unit 14 is information related to the OS (Operating System) of the suction device 1, such as the control contents of various components by the control unit 16. Another example of the information stored in the memory unit 14 is information related to suction by the user, such as the number of suctions, suction times, and cumulative suction time.

[0016] The communication unit 15 is a communication interface for sending and receiving information between the suction device 1 and other devices. The communication unit 15 communicates in accordance with any wired or wireless communication standard. Examples of such communication standards include wireless LAN (Local Area Network), wired LAN, Wi-Fi (registered trademark), or Bluetooth (registered trademark). As an example, the communication unit 15 transmits information about the user's suction to the smartphone in order to display the information about the user's suction on the smartphone. As another example, the communication unit 15 receives new OS information from the server in order to update the OS information stored in the storage unit 14.

[0017] The control unit 16 functions as an arithmetic processing unit and control unit, controlling the overall operation of the suction device 1 according to various programs. The control unit 16 is implemented by electronic circuits such as a CPU (Central Processing Unit) and a microprocessor. In addition, the control unit 16 may include a ROM (Read Only Memory) for storing the programs and calculation parameters to be used, and a RAM (Random Access Memory) for temporarily storing parameters that change as needed. The suction device 1 performs various processes based on the control of the control unit 16. Examples of processes controlled by the control unit 16 include supplying power from the power supply unit 11 to other components, charging the power supply unit 11, detecting information by the sensor unit 12, notifying information by the notification unit 13, storing and reading information by the storage unit 14, and transmitting and receiving information by the communication unit 15. Other processes performed by the suction device 1, such as inputting information to each component and processing based on information output from each component, are also controlled by the control unit 16.

[0018] The operation unit 17 consists of button-type switches, etc. However, the operation unit 17 may also consist of a touch panel, etc. The operation unit 17 is provided in a state exposed from the surface of the cover 75. The operation unit 17 outputs information operated by the user to the control unit 16. For example, when the power supply unit 10 is in the OFF state, if a predetermined startup operation is performed on the operation unit 17, the operation unit 17 outputs a startup command for the power supply unit 10 to the control unit 16. When the control unit 16 receives this startup command, it starts up the power supply unit 10. An example of a predetermined startup operation by the operation unit 17 is pressing the operation unit 17 three times in quick succession.

[0019] As shown in Figure 2, the power supply unit 10 includes a holder 20 for holding the power supply unit 11, a circuit board module 30 that constitutes the control unit 16, and a sensor cover 40 that covers the area around the pressure sensor 12p.

[0020] [Holder 20] The holder 20 has a semi-cylindrical base portion 21 with the center line CL as its center line, a disc-shaped portion 22 provided at the second end of the base portion 21 in the direction of the center line, and a clamping portion 23 that, together with the disc-shaped portion 22, sandwiches the mounting portion 41 of the sensor cover 40, which will be described later. The holder 20 is integrally formed from, for example, a resin material.

[0021] The base portion 21 is formed in a semi-cylindrical shape with the center line CL as its center line, and is capable of receiving the power supply unit 11. The base portion 21 may have a shape other than semi-cylindrical, as long as it has an opening for receiving the power supply unit 11.

[0022] An opening 25 is formed in the second portion of the base portion 21 in the direction of the centerline, which is opened to expose the operating portion 17 from the cover 75. The opening 25 penetrates a portion of the base portion 21 in the radial direction. The base portion 21 has a projection 26 that extends from the outer periphery toward the center line CL, surrounding the opening 25. The base portion 21 has a partition wall 27 located on the first side in the direction of the centerline from the protruding portion 26, which divides the base portion 21 into a portion that holds the power supply unit 11 and the other portion.

[0023] Multiple through holes 22a are formed in the disc-shaped portion 22 in the direction of the centerline. One end 51 of the electromagnetic induction source 50, which will be described later, passes through the through holes 22a toward the substrate module 30. Also, the lead wire 72 of the temperature sensor 70, which will be described later, passes through the through holes 22a toward the substrate module 30. The clamping portion 23 is semi-circular in shape, protruding from the inner circumferential surface of the base portion 21 toward the center line CL.

[0024] [Board module 30] The board module 30 comprises a board 31 and a switch element 32 mounted on the board 31. The circuit board 31 is positioned parallel to the centerline direction and perpendicular to the protrusion 26. The circuit board 31 is fixed to the base portion 21 of the holder 20, for example, with screws. The circuit board 31 is connected to the power supply unit 11 via connecting wires (not shown). An MCU (Micro Controller Unit) (not shown) that realizes the control unit 16 is mounted on the circuit board 31. A pressure sensor 12p is also mounted on the circuit board 31.

[0025] The switch element 32 is positioned on the surface of the substrate 31 facing the protruding portion 26, in a position that overlaps with the opening 25 in the radial direction. In the example shown in Figure 2, the switch element 32 is surface-mounted on the substrate 31. However, the switch element 32 may also be mounted on the substrate 31 with the connection terminals extending from the switch element 32 inserted through the through-holes in the substrate 31. The switch element 32 is positioned offset to the first side in the direction of the centerline relative to the pressure sensor 12p. In other words, the switch element 32 is positioned so as not to overlap with the pressure sensor 12p when viewed radially from the outside of the base portion 21.

[0026] [Sensor cover 40] The sensor cover 40 is molded from a resin material that is softer and more elastic than the holder 20, such as silicone resin. The sensor cover 40 has a mounting portion 41 that is attached to the holder 20 and a covering portion 42 that covers the pressure sensor 12p.

[0027] The mounting portion 41 is formed in a semi-cylindrical shape with its centerline in the direction of the center line and located on the opposite side from the base portion 21 in the circumferential direction. The mounting portion 41 is fitted between the disc-shaped portion 22 and the clamping portion 23 of the holder 20. The mounting portion 41 has a through hole 41a formed in the direction of the center line. In addition, the mounting portion 41 has a groove 41b formed on the second side surface in the direction of the center line that connects the through hole 41a and the space between the disc-shaped portion 22 and the clamping portion 23 of the holder 20 when the sensor cover 40 is attached to the holder 20.

[0028] The cover portion 42 is provided so as to extend from the outer circumference of the mounting portion 41 toward the first side in the direction of the centerline, and is formed in a concave shape so as to be open toward the centerline CL in the radial direction. The cover portion 42 has a plurality of protrusions 42b that project toward the centerline CL from the concave bottom portion 42a. A radial through hole 42c is formed in the bottom portion 42a, which connects the concave interior and the exterior. The pressure sensor 12p is fitted into the concave interior of the cover portion 42 until it abuts against the protrusions 42b. As a result, a gap is formed between the bottom surface of the bottom portion 42a and the pressure sensor 12p.

[0029] As shown in Figure 2, the space enclosed by the sensor cover 40 constitutes a pressure fluctuation chamber S1 in which the pressure fluctuates through the through-hole 41a of the mounting portion 41 described above in response to the suction of the suction device 1. On the other hand, the space within the cover 75 other than the pressure fluctuation chamber S1 constitutes a normal pressure chamber S2 in which atmospheric pressure acts. In this embodiment, of the power supply unit 11 and the circuit board module 30, all except the pressure sensor 12p are housed in the normal pressure chamber S2.

[0030] (Base material 100) The base material 100 includes a base material portion 101, a filter 102, and a container 110 that houses the base material portion 101 and the filter 102.

[0031] The base material 101 contains an aerosol source. The aerosol source is atomized by heating, generating an aerosol. The aerosol source may be tobacco-derived, such as processed products made by molding shredded tobacco or tobacco raw materials into granules, sheets, or powder. The aerosol source may also contain non-tobacco-derived materials made from plants other than tobacco (e.g., mint and herbs). As an example, the aerosol source may contain fragrance components such as menthol. If the inhalation device 1 is a medical inhaler, the aerosol source may contain medication for the patient to inhale.

[0032] The container 110 is formed from a magnetic material. Examples of magnetic materials include iron and ferritic stainless steel. Furthermore, the container 110 is formed by press working. The container 110 has a cylindrical portion 111, a bottom portion 112 that closes the first end of the cylindrical portion 111 in the direction of the centerline, and a protruding portion 113 that extends radially outward from the second end of the cylindrical portion 111 in the direction of the centerline over its entire circumference.

[0033] The outer diameter of the cylindrical portion 111 is smaller than the inner diameter of the cylindrical portion 61 of the support member 60, which will be described later, and the cylindrical portion 111 and the base material portion 101 are housed inside the support member 60. Multiple through-holes 115 are formed in the bottom portion 112 in the direction of the centerline. The size of the through-holes 115 is smaller than the size of the aerosol source (for example, the size of the through-holes 115 is 1 / 10 or less of the size of the aerosol source), making it difficult for the aerosol source to escape to the outside through the through-holes 115.

[0034] The outer diameter of the protrusion 113 is larger than the outer diameter of the cylindrical portion 61 of the support member 60 (described later) and smaller than the inner diameter of the cover 75. The container 110 is then housed inside the cover 75 with the protrusion 113 resting on the second end face of the cylindrical portion 61 of the support member 60 in the direction of the centerline.

[0035] (electromagnetic induction source 50) The electromagnetic induction source 50 generates heat in the container 110 of the base material 100 through electromagnetic induction. The electromagnetic induction source 50 is composed of a coiled conductor and is arranged to wrap around the outer circumference of the support member 60. The conductor can be exemplified as a polyurethane copper wire in which an insulating coating (resin) is applied to the conductor and baked on. One end 51 of the electromagnetic induction source 50 is passed through a through hole 22a formed in the disc-shaped portion 22 of the holder 20 and is connected to the substrate 31 via a lead wire 53. The other end 52 of the electromagnetic induction source 50 passes through a gap formed between the disc-shaped portion 22 of the holder 20 and the cover 75 toward the first side in the direction of the centerline and is connected to the substrate 31 via, for example, a lead wire (not shown). Note that one end 51 and the other end 52 may each be directly connected to the substrate 31.

[0036] The electromagnetic induction source 50 generates a magnetic field when an alternating current is supplied from the power supply unit 11. The electromagnetic induction source 50 is positioned so that the container 110 of the base material 100, supported by the support member 60, is superimposed on the magnetic field it generates. Therefore, when a magnetic field is generated with the base material 100 supported by the support member 60, eddy currents are generated in the container 110, and Joule heat is generated. This Joule heat then heats and atomizes the aerosol source contained in the base material 100, generating an aerosol. For example, power may be supplied and an aerosol may be generated when a predetermined operation is performed by the user on the operation unit 17. When the temperature of the base material 100, which has been induced and heated by the electromagnetic induction source 50, reaches a predetermined temperature, the user can use suction. Subsequently, when the number of times the pressure detected by the pressure sensor 12p falls below a predetermined value reaches a predetermined number of times, power may be stopped.

[0037] (Support member 60) The support member 60 is molded from a non-magnetic material. Examples of non-magnetic materials include synthetic resin and austenitic stainless steel. The support member 60 has a cylindrical portion 61 and a bottom portion 62 that closes the first end of the cylindrical portion 61 in the direction of the centerline. A through hole 63 in the direction of the centerline is formed in the bottom portion 62. An electromagnetic induction source 50, wound in a spiral shape, is arranged on the outer circumferential surface of the cylindrical portion 61.

[0038] In Figure 2, the support member 60 is shown with a cylindrical portion 61 and a bottom portion 62 integrally formed, but the cylindrical portion 61 and the bottom portion 62 may be formed as separate parts. Furthermore, the support member 60 only has a disc-shaped member corresponding to the bottom portion 62 and does not need to have a cylindrical member corresponding to the cylindrical portion 61 that is positioned inside the electromagnetic induction source 50.

[0039] (Temperature sensor 70) The temperature sensor 70 can be exemplified as a thermistor having a detection unit 71 and lead wires 72. In the example shown in Figure 2, the temperature sensor 70 has the detection unit 71 positioned on the second side in the direction of the centerline of the bottom 62 of the support member 60. The detection unit 71 can be exemplified as being bonded to the bottom 62 with a thermally conductive adhesive such as epoxy. The lead wires 72 are passed through through holes 63 in the bottom 62 of the support member 60 and through holes 22a in the disc-shaped portion 22, and each of the two ends provided at the tip is connected to the substrate 31.

[0040] The detection signal from the temperature sensor 70 is input to the control unit 16. The control unit 16 then controls a driver (not shown) mounted on the substrate 31 based on the temperature detected by the temperature sensor 70, and varies the high-frequency current supplied to the electromagnetic induction source 50. In this way, the control unit 16 controls the temperature of the substrate 100 so that it reaches the target temperature specified in the heating profile stored in the ROM. The temperature sensor 70 may also be a thermocouple.

[0041] (Cover 75) The cover 75 is formed in a cylindrical shape with the center line CL as its center. The holder 20 is inserted inside the cover 75. An exposure hole 76 for exposing the operating part 17 is formed in the cover 75 at the part of the base portion 21 of the holder 20 that faces the opening 25.

[0042] An operating unit 17 is housed within the exposed hole 76 of the cover 75 and the opening 25 of the holder 20. The operating unit 17 is configured to be movable in the radial direction while being supported by the protruding portion 26. As the operating unit 17 moves radially toward the center line CL, it presses against the switch element 32. Note that the operating unit 17 is not limited to moving radially; for example, it may slide in the direction of the center line. The operating unit 17 may also be a touch sensor.

[0043] (End cap 80) The end cap 80 has a cylindrical first cylindrical portion 81 that fits inside the second opening of the cover 75, and a cylindrical second cylindrical portion 82 provided on the outside of the cover 75. The first cylindrical portion 81 has a flange portion 83 that abuts against the end face of the cover 75, with a portion of the cover 75 side fitted inside the second opening in the cover 75. The second cylindrical portion 82 has an outer diameter smaller than the outer diameter of the first cylindrical portion 81, and an inner diameter that is the same as the inner diameter of the first cylindrical portion 81. The end cap 80 may be molded from resin or metal, for example.

[0044] In the example shown in Figure 1, the end cap 80 is fixed to the cover 75 by screw fastening a male thread formed on the outer circumferential surface of the first cylindrical portion 81 to a female thread formed on the inner circumferential surface of the cover 75. Alternatively, the end cap 80 may be fixed to the cover 75 by press-fitting the first cylindrical portion 81 into the cover 75.

[0045] When the end cap 80 is attached to the cover 75, the first end of the first cylindrical portion 81 in the direction of the centerline comes into contact with the container 110 of the base material 100, and the container 110 is pressurized toward the first side. This maintains contact between the bottom 112 of the container 110 and the detection part 71 of the temperature sensor 70. In addition, movement of the base material 100 toward the second side in the direction of the centerline is suppressed. In the example shown in Figure 2, the protruding portion 113 of the container 110 is in contact with the second end of the cylindrical portion 61 of the support member 60 in the direction of the centerline, but the protruding portion 113 and the cylindrical portion 61 do not necessarily have to be in contact.

[0046] (Mouthpiece 90) The mouthpiece 90 is a cylindrical member, with a portion of its first side in the direction of the centerline fitted inside the end cap 80, and a flange portion 91 that abuts against the end face of the end cap 80. The mouthpiece 90 can be exemplified as being molded from resin. The mouthpiece 90 is a component that the user holds in their mouth during suction. The mouthpiece 90 has an air outlet hole 92. By holding the mouthpiece 90 in their mouth and suctioning, the user can take in a mixed fluid of aerosol and air into their oral cavity. Furthermore, the mouthpiece 90 and the end cap 80 may be integrally molded from resin.

[0047] (Operation of suction device 1) In the suction device 1 configured in this way, the user can make the aerosol available for suction by inserting the container 110 filled with the aerosol source into the inside of the electromagnetic induction source 50, in other words, into the support member 60, and inductively heating it using the electromagnetic induction source 50. When the user suctions, the aerosol generated by the heating of the aerosol source contained in the container 110 flows in, for example, through the gap between the operating unit 17 and the cover 75, and is mixed with air that has passed through the through-hole 22a of the disc-shaped part 22, the through-hole 63 of the bottom 62 of the support member 60, and the through-hole 115 of the bottom 112 of the container 110. The mixed fluid of aerosol and air then passes through the filter 102 and is transported to the air outlet hole 92 formed in the mouthpiece 90.

[0048] After the aerosol inhalation is complete, the user can remove the container 110 from inside the electromagnetic induction source 50 and reinsert a new container 110 inside the electromagnetic induction source 50 to make it possible to inhale the aerosol again. Alternatively, the user can remove and discard the heated base material 101 and filter 102 from the container 110 that has been removed from inside the electromagnetic induction source 50, then put a new base material 101 and filter 102 into the container 110 and reinsert this container 110 inside the electromagnetic induction source 50 to make it possible to inhale the aerosol again. Furthermore, since the container 110 is provided with a bottom 112, the heated aerosol source tends to remain inside the container 110 after inhalation, and it is suppressed that some of the heated aerosol source remains inside the electromagnetic induction source 50 after the container 110 is removed. Therefore, with the suction device 1, for example, compared to a configuration in which a stick-shaped substrate containing an aerosol source is heated, the need to remove a portion of the heated aerosol source for maintenance of the suction device 1 is reduced, thus reducing the effort required for maintenance.

[0049] Furthermore, the suction device 1 includes a temperature sensor 70 positioned opposite the bottom 112 of the container 110 to detect the temperature of the container 110, and an end cap 80 as an example of a stopper member that causes the bottom 112 of the container 110 to abut against the temperature sensor 70. In the suction device 1 configured in this way, the temperature sensor 70 is positioned opposite the bottom 112 of the container 110, and the end cap 80 causes the bottom 112 of the container 110 to abut against the detection part 71 of the temperature sensor 70, so that the bottom 112 of the container 110 and the detection part 71 of the temperature sensor 70 can be brought into contact, and the temperature of the container 110 can be detected with high accuracy.

[0050] Therefore, the suction device 1 reduces the maintenance effort required for the suction device 1, and allows for highly accurate detection of the temperature of the container 110 that heats the substrate portion 101 containing the aerosol source. By accurately detecting the temperature of the container 110, the control unit 16 can prevent the temperature difference between the substrate 100 and the target temperature from becoming too large. As a result, the suction device 1 ensures that the temperature of the substrate portion 101 filled in the container 110 reaches an appropriate temperature.

[0051] <Second Embodiment> Figure 4 is an example of a cross-sectional view showing an example of the schematic configuration of the suction device 2 according to the second embodiment. The suction device 2 according to the second embodiment differs from the suction device 1 according to the first embodiment in the shape of the support member 260, which corresponds to the support member 60, and in the position where the temperature sensor 70 is provided. The differences from the first embodiment will be described below. The same reference numerals are used for the same parts in the first and second embodiments, and their detailed descriptions will be omitted.

[0052] The support member 260 has a cylindrical portion 261. In the center of the cylindrical portion 261 in the direction of the centerline, there is a recess 262 recessed from the inner circumferential surface and a radial through hole 263 connecting the recess 262 and the outside of the cylindrical portion 261. The detection part 71 of the temperature sensor 70 is positioned in the recess 262. The lead wires 72 of the temperature sensor 70 pass through the through hole 263 and also through the wires of the electromagnetic induction source 50 which is spirally wound around the outer surface of the cylindrical portion 261, through the gap between the radially outer side of the electromagnetic induction source 50 and the inner circumferential surface of the cover 75, and through the through hole 22a of the disc-shaped portion 22, with each of the two ends provided at the tip connected to the substrate 31.

[0053] Thus, the suction device 2 includes a support member 260, which is an example of a cylindrical non-magnetic member, arranged around a cylindrical container 110 having a bottom 112 and filled with an aerosol source, and an electromagnetic induction source 50, which is formed by spirally winding a conductor around the outer surface of the support member 260 and heats the container 110 by induction heating. The suction device 2 also includes a temperature sensor 70 having a detection unit 71 which is arranged inside the support member 260 so as to overlap with the area where the container 110 is provided in the direction of the centerline of the support member 260 and detects the temperature of the container 110, and a lead wire 72 which is drawn out from the detection unit 71 to the radially outside of the electromagnetic induction source 50 through the conductors in the electromagnetic induction source 50 and outputs a detected value.

[0054] In the suction device 2 configured in this way, the detection unit 71 is positioned so as to overlap with the area where the container 110 is located in the direction of the centerline, so the temperature sensor 70 detects the temperature of the cylindrical portion 111 of the container 110. Therefore, the suction device 2 reduces the maintenance effort required for the suction device 2, and allows for highly accurate detection of the temperature of the container 110 that heats the substrate portion 101 containing the aerosol source. By accurately detecting the temperature of the container 110, the control unit 16 can prevent the temperature difference between the substrate 100 and the target temperature from becoming too large.

[0055] Furthermore, the temperature sensor 70 detects the temperature of the central part in the direction of the centerline of the cylindrical portion 111 of the container 110, where Joule heating is likely to occur. Therefore, the suction device 2 can detect the temperature near the part of the substrate portion 101 containing the aerosol source that is most likely to become hot, and thus the current supplied to the electromagnetic induction source 50 can be controlled so that the temperature of the aerosol does not become too high.

[0056] Furthermore, it is desirable to position the detection unit 71 of the temperature sensor 70 so that it is in contact with the outer circumferential surface of the cylindrical portion 111 of the container 110. For example, it is preferable to make the radial distance from the center line CL to the detection unit 71 smaller than the radius of the outer circumferential surface of the cylindrical portion 111. In addition, it is preferable to make the outer diameter of the protruding portion 113 of the container 110 and the diameter of the inner circumferential surface of the cover 75 approximately the same so that the center line of the container 110 and the center line CL can be aligned. Alternatively, a convex portion protruding from the inner circumferential surface may be provided on the cylindrical portion 261 of the support member 260 on the side opposite to the recess 262 with respect to the center line CL, and the distance between this convex portion and the detection unit 71 may be made smaller than the diameter of the outer circumferential surface of the cylindrical portion 111 of the container 110. Furthermore, at each point where the line connecting the convex portion and the concave portion 262, and the line perpendicular to the center line CL, intersect with the inner circumferential surface of the cylindrical portion 261 of the support member 260, a convex portion protruding from the inner circumferential surface may be provided, such that the diameter of the virtual circle drawn by these three convex portions and the detection portion 71 is smaller than the diameter of the outer circumferential surface of the cylindrical portion 111 of the container 110.

[0057] The detection unit 71 of the temperature sensor 70 comes into contact with the outer surface of the cylindrical portion 111 of the container 110, allowing the temperature sensor 70 to detect the temperature of the container 110 with high accuracy. By accurately detecting the temperature of the container 110, the control unit 16 can prevent the temperature difference between the temperature of the container 110, and consequently the temperature of the base material 101 filled in the container 110, and the target temperature from becoming too large.

[0058] (Modified form of support member 260 and container 110) Figure 5 shows an example of the schematic configuration of the support member 260 and container 110 in a modified example. As shown in Figure 5, the inner surface of the support member 260 and the outer surface of the cylindrical portion 111 of the container 110 may be inclined with respect to the centerline direction so that the detection part 71 of the temperature sensor 70 and the outer surface of the cylindrical portion 111 of the container 110 can easily come into contact. Specifically, the diameter of the inner surface of the support member 260 is gradually increased from the first side to the second side in the centerline direction, and the diameter of the outer surface of the cylindrical portion 111 of the container 110 is gradually increased from the first side to the second side in the centerline direction. This makes it easier for the detection part 71 of the temperature sensor 70 and the outer surface of the cylindrical portion 111 of the container 110 to come into contact when the container 110 is inserted into the support member 260. Furthermore, the outer circumferential surface of the support member 260 may be inclined with respect to the center line direction so that the wall thickness of the support member 260 is uniform. Also, the inner circumferential surface of the cylindrical portion 111 of the container 110 may be inclined with respect to the center line direction so that the wall thickness of the container 110 is uniform.

[0059] <Third Embodiment> Figure 6 is an example of a cross-sectional view showing an example of the schematic configuration of the suction device 3 according to the third embodiment. The suction device 3 according to the third embodiment differs from the suction device 2 according to the second embodiment in the shape of the support member 360, which corresponds to the support member 260, and in the position where the temperature sensor 70 is provided. The differences from the second embodiment will be described below. The same reference numerals are used for the same parts in the second and third embodiments, and their detailed descriptions will be omitted.

[0060] The support member 360 has a cylindrical portion 361. At the second end of the cylindrical portion 361 in the direction of the centerline, there is a recess 362 recessed from the inner circumferential surface and a radial through hole 363 connecting the recess 362 to the outside of the cylindrical portion 361. The detection part 71 of the temperature sensor 70 is positioned in the recess 362. The lead wires 72 of the temperature sensor 70 pass through the through hole 363 and also pass second to the centerline of the electromagnetic induction source 50 located outside the cylindrical portion 361, through the gap between the radially outer side of the electromagnetic induction source 50 and the inner circumferential surface of the cover 75, and through the through hole 22a of the disc-shaped portion 22, with each of the two ends provided at the tip connected to the substrate 31.

[0061] Thus, the suction device 3 includes a support member 360, which is an example of a cylindrical non-magnetic member, arranged around a cylindrical container 110 having a bottom 112 and filled with an aerosol source, and an electromagnetic induction source 50 arranged around the support member 360 to heat the container 110 by induction heating. The suction device 3 also includes a temperature sensor 70 having a detection unit 71 which is arranged inside the support member 360 so as to overlap with the area where the container 110 is provided in the direction of the centerline of the support member 360 and detects the temperature of the container 110, and a lead wire 72 which is drawn out from the detection unit 71 to the radially outside of the electromagnetic induction source 50, passing outside the centerline of the electromagnetic induction source 50 and outputting a detected value.

[0062] In the suction device 3 configured in this way, the detection unit 71 is positioned so as to overlap with the area where the container 110 is located in the direction of the centerline, so the temperature sensor 70 detects the temperature of the cylindrical portion 111 of the container 110. Therefore, the suction device 3 reduces the maintenance effort required for the suction device 3, and allows for highly accurate detection of the temperature of the container 110 that heats the substrate portion 101 containing the aerosol source. By accurately detecting the temperature of the container 110, the control unit 16 can prevent the temperature difference between the substrate 100 and the target temperature from becoming too large.

[0063] Furthermore, the temperature sensor 70 can detect the temperature of the cylindrical portion 111 of the container 110, where Joule heating is easily generated, thereby detecting the temperature near the parts of the substrate portion 101 containing the aerosol source that tend to become hot. As a result, the control unit 16 can control the current supplied to the electromagnetic induction source 50 so that the temperature of the aerosol does not become too high. Furthermore, in order to position the detection unit 71 of the temperature sensor 70 so that it contacts the outer circumferential surface of the cylindrical portion 111 of the container 110, it is desirable to position the detection unit 71 and to provide a protrusion that extends from the inner circumferential surface of the cylindrical portion 361 of the support member 360, as described in the second embodiment. In addition, the inner circumferential surface of the support member 360 and the outer circumferential surface of the cylindrical portion 111 of the container 110 may be inclined with respect to the centerline direction.

[0064] <Fourth Embodiment> Figure 7 is an example of a cross-sectional view showing an example of the schematic configuration of the suction device 4 according to the fourth embodiment. The suction device 4 according to the fourth embodiment differs from the suction device 2 according to the second embodiment in the shape of the support member 460, which corresponds to the support member 260, and in the position where the temperature sensor 70 is provided. The differences from the second embodiment will be described below. The same reference numerals are used for the same parts in the second and fourth embodiments, and their detailed descriptions will be omitted.

[0065] The support member 460 has a cylindrical portion 461. At the first end of the cylindrical portion 461 in the direction of the centerline, there is a recess 462 recessed from the inner circumferential surface and a radial through hole 463 connecting the recess 462 to the outside of the cylindrical portion 461. The detection unit 71 of the temperature sensor 70 is positioned in the recess 462. The lead wires 72 of the temperature sensor 70 pass through the through hole 463, and also pass first in the direction of the centerline from the electromagnetic induction source 50 located outside the cylindrical portion 461, and pass through the through hole 22a of the disc-shaped portion 22, with each of the two ends provided at the tip connected to the substrate 31.

[0066] Thus, the suction device 4 includes a support member 460, which is an example of a cylindrical non-magnetic member, arranged around a cylindrical container 110 having a bottom 112 and filled with an aerosol source, and an electromagnetic induction source 50 arranged around the support member 460 to heat the container 110 by induction heating. The suction device 4 also includes a temperature sensor 70 having a detection unit 71 which is arranged inside the support member 460 so as to overlap with the area where the container 110 is provided in the direction of the centerline of the support member 460 and detects the temperature of the container 110, and a lead wire 72 which is drawn out from the detection unit 71 to the radially outside of the electromagnetic induction source 50, passing outside the centerline of the electromagnetic induction source 50 and outputting a detected value.

[0067] In the suction device 4 configured in this way, similar to the suction device 3, the maintenance effort for the suction device 4 can be reduced, and the temperature of the container 110 that heats the substrate portion 101 containing the aerosol source can be detected with high accuracy. By accurately detecting the temperature of the container 110, the control unit 16 can prevent the temperature difference between the substrate 100 temperature and the target temperature from becoming too large.

[0068] Furthermore, the suction device 4 further includes a substrate 31 to which the ends of the lead wires 72 are connected, and the detection unit 71 is located at the first end of the support member 460 in the direction of the centerline, and the lead wires 72 are drawn out radially outward from the electromagnetic induction source 50 on the first side in the direction of the centerline, which is closer to the substrate 31 than the electromagnetic induction source 50 in the direction of the centerline. Therefore, the length of the lead wires 72 can be shortened. Furthermore, in order to position the detection unit 71 of the temperature sensor 70 so that it contacts the outer circumferential surface of the cylindrical portion 111 of the container 110, it is desirable to position the detection unit 71 and to provide a protrusion that extends from the inner circumferential surface of the cylindrical portion 461 of the support member 460, as described in the second embodiment. In addition, the inner circumferential surface of the support member 460 and the outer circumferential surface of the cylindrical portion 111 of the container 110 may be inclined with respect to the direction of the centerline.

[0069] <Fifth Embodiment> Figure 8 is an example of a cross-sectional view showing an example of the schematic configuration of the suction device 5 according to the fifth embodiment. The suction device 5 according to the fifth embodiment differs from the suction device 1 according to the first embodiment in the position where the temperature sensor 70 is provided, the shape of the cover 575 corresponding to the cover 75, and the shape of the end cap 80 and the opening / closing member 590 corresponding to the mouthpiece 90. The differences from the first embodiment will be described below. The same reference numerals are used for the same parts in the first and fifth embodiments, and their detailed descriptions will be omitted.

[0070] In the suction device 5, the cover 575 and the opening / closing member 590 are connected by a hinge 550, and the opening / closing member 590 is configured to open and close relative to the cover 575. Furthermore, the cover 575 and the opening / closing member 590 form a restraining part 570 that prevents the opening / closing member 590 from separating from the cover 575 when the opening / closing member 590 closes the opening of the cover 575. The detection part 71 of the temperature sensor 70 is attached to the opening / closing member 590.

[0071] More specifically, the opening / closing member 590 has a cylindrical first cylindrical portion 591 provided on the first side in the direction of the centerline, a cylindrical second cylindrical portion 592 provided on the second side in the direction of the centerline, and a connecting portion 593 that connects the first cylindrical portion 591 and the second cylindrical portion 592. The second cylindrical portion 592 has an outer diameter smaller than that of the first cylindrical portion 591, and an inner diameter that is the same as that of the first cylindrical portion 591. The diameter of the inner circumferential surface of the connecting portion 593 is the same as the diameter of the inner circumferential surface of the first cylindrical portion 591, and the diameter of the outer circumferential surface gradually decreases from the first cylindrical portion 591 toward the second cylindrical portion 592.

[0072] A recess 594 is formed at the first end of the first cylindrical portion 591 in the direction of the centerline, which is recessed from the end face and extends radially. The detection unit 71 of the temperature sensor 70 is located in the part of the recess 594 on the side of the centerline CL. The lead wires 72 of the temperature sensor 70 extend radially from the side of the centerline CL, pass outside the protruding portion 113 of the container 110 and the electromagnetic induction source 50 in the radial direction, and also pass through the through hole 22a of the disc-shaped portion 22, with each of the two ends provided at the tip connected to the substrate 31.

[0073] At the first end of the first cylindrical portion 591 in the direction of the centerline, a projection 551 is provided that protrudes outward from the outer circumferential surface and has a through hole through which a pin 553 passes. Furthermore, at the first end of the first cylindrical portion 591 in the direction of the centerline, on the side opposite to the projection 551 with respect to the centerline CL, a hook 571 is provided that protrudes outward from the outer circumferential surface and constitutes a restraining portion 570.

[0074] The cover 575 is cylindrical, and at the second end of the cover 575 in the direction of the centerline, there is a projection 552 that protrudes outward from the outer circumferential surface and has a through hole through which the pin 553 passes. Furthermore, at the second end of the cover 575 in the direction of the centerline, on the side opposite to the projection 552 with respect to the centerline CL, there is a convex portion 572 that protrudes outward from the outer circumferential surface and constitutes a restraining portion 570.

[0075] The hinge 550 is formed by passing a pin 553 through a through hole formed in the protruding portion 551 of the opening / closing member 590 and a through hole formed in the protruding portion 552 of the cover 575. In addition, the restraining portion 570 is formed by hooking the hook 571 of the opening / closing member 590 onto the protruding portion 572 of the cover 575.

[0076] Thus, the suction device 5 is positioned inside a cover 575, which is an example of an insertion part into which a cylindrical container 110 having a bottom 112 and filled with an aerosol source is inserted, and includes an electromagnetic induction source 50 that heats the container 110 by induction heating. The suction device 5 also includes an opening / closing member 590 that transitions between a state that covers the opening 576 of the cover 575 and a state that leaves the opening 576 open, and when in the covering state, has an air outlet hole 595 formed therein, which is an example of an outlet for the aerosol generated by heating the aerosol source. The suction device 5 also includes a temperature sensor 70 attached to the opening / closing member 590 that detects the temperature of the container 110.

[0077] The container 110 has a cylindrical portion 111 as an example of a cylindrical section, and a protruding portion 113 that projects outward from the cylindrical portion 111 at a point opposite to the bottom portion 112 in the direction of the centerline. The temperature sensor 70 has a detection unit 71 that is positioned opposite the protruding portion 113 in the direction of the centerline to detect the temperature of the container 110, and a lead wire 72 that passes outside the radial direction of the electromagnetic induction source 50 and is connected to the substrate 31 to output the detected value.

[0078] In the suction device 5 configured in this way, the detection unit 71 of the temperature sensor 70 can be brought into contact with the protruding part 113 of the container 110, so the temperature of the container 110 can be detected with high accuracy. Therefore, the suction device 5 can also reduce maintenance effort and accurately detect the temperature of the container 110 that heats the substrate portion 101 containing the aerosol source. By accurately detecting the temperature of the container 110, the control unit 16 can prevent the temperature difference between the substrate 100 and the target temperature from becoming too large. As a result, the suction device 5 can ensure that the temperature of the substrate portion 101 filled in the container 110 reaches an appropriate temperature.

[0079] The opening / closing member 590 corresponds to the end cap 80 and the mouthpiece 90, but is not limited to this configuration. For example, the opening / closing member 590 may correspond to the end cap 80, and a member that can be held in the user's mouth during suction (e.g., the mouthpiece 90) may be attached to the opening / closing member 590.

[0080] <Sixth Embodiment> Figure 9 is an example of a cross-sectional view showing an example of the schematic configuration of the suction device 6 according to the sixth embodiment. The suction device 6 according to the sixth embodiment differs from the suction device 1 according to the first embodiment in that the airflow path to be drawn into the user is different. The differences from the first embodiment will be described below. The same reference numerals are used for the same components in the first and sixth embodiments, and their detailed descriptions will be omitted.

[0081] Unlike the container 110 of the first embodiment, the container 610 of the sixth embodiment, which corresponds to the container 110 of the first embodiment, does not have a through hole 115. In the cover 675 according to the sixth embodiment, which corresponds to the cover 75 according to the first embodiment, a communication hole 676 is formed that penetrates radially and connects the outside and inside of the cover 675, in a portion that is second in the centerline direction from the holder 20 and first in the centerline direction from the protruding portion 113 of the container 110. It can be exemplified that a plurality of communication holes 676 are formed in the circumferential direction.

[0082] Furthermore, the end cap 680 according to the sixth embodiment, which corresponds to the end cap 80 according to the first embodiment, has a groove 684 formed at the first end of the flange portion 83 in the direction of the centerline, recessed from the end face toward the second side. The groove 684 is formed over the entire radial area of ​​the flange portion 83, from the outer circumference to the inner circumference. It can also be illustrated that multiple grooves 684 are formed in the circumferential direction.

[0083] (Operation of suction device 6) In the suction device 6 configured in this way, the user can make the aerosol ready for suction by inserting the container 610 filled with the aerosol source into the support member 60 and inductively heating it using the electromagnetic induction source 50. When the user suctions, as shown in Figure 9, the aerosol generated by heating the aerosol source contained in the container 610 flows in through the communication hole 676 formed in the cover 675 and mixes with the air that has passed through the gap between the protrusion 113 of the container 610 and the cover 675, and through the groove 684 of the end cap 680. The mixed fluid of aerosol and air is then transported through the inside of the mouthpiece 90 to the air outlet hole 92 formed in the mouthpiece 90.

[0084] Furthermore, the suction device 6 configured as described above has the additional effect of preventing any portion of the heated aerosol source from remaining inside the electromagnetic induction source 50 after the container 610 is removed, in addition to the effects of the suction device 1 according to the first embodiment described above, because no through hole 115 is formed in the bottom 112 of the container 610.

[0085] In addition, in the suction devices 2 to 5 according to the second to fifth embodiments, similar to the suction device 6 according to the sixth embodiment, a through hole 115 may not be formed in the bottom 112 of the container 110, and the aerosol generated by heating the aerosol source contained in the container 110 may be mixed with air that flows in through a communication hole formed in the cover 75 at a location that is second in the direction of the centerline from the holder 20 and first in the direction of the centerline from the protruding portion 113 of the container 110, and then discharged.

[0086] Furthermore, while the suction devices 1 to 5 according to the first to fifth embodiments described above are configured to have one temperature sensor 70, the invention is not limited to this configuration, and multiple temperature sensors 70 may be provided. In addition, when multiple temperature sensors are provided, multiple temperature sensors 70 may be placed at the same locations as each of the suction devices 1 to 5. For example, in the suction device 2 according to the second embodiment, multiple temperature sensors 70 may be provided such that the detection unit 71 is placed not only at the center of the cylindrical portion 261 of the support member 260 in the direction of the centerline, but also at at least one of the first end in the direction of the centerline (similar to the position of suction device 4) and the second end in the direction of the centerline (similar to the position of suction device 3). By providing multiple temperature sensors 70, the temperature of the container 110 can be detected with greater accuracy. [Explanation of Symbols]
