In the present specification and drawings, constituent elements having substantially the same functional configuration are denoted by the same reference numerals, thereby omitting redundant description.

<1. Configuration of Suction Device>
First, a configuration example of a suction device according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram showing a configuration example of a suction device 100 according to this embodiment.

As shown in FIG. 1, the suction device 100 includes, for example, 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 susceptor 161, an electromagnetic induction A source 162 and a retainer 140 are provided.

The suction device 100 according to the present embodiment performs induction heating (IH) on the stick-shaped substrate 150 including the aerosol source while the stick-shaped substrate 150 is held by the holding portion 140 . As a result, the aerosol source contained in the stick-shaped substrate 150 is atomized to generate an aerosol from the stick-shaped substrate 150 . The generated aerosol is inhaled by the user.

Note that the suction device 100 and the stick-shaped base material 150 cooperate to generate an aerosol that is sucked by the user. As such, the combination of suction device 100 and stick-type substrate 150 may be viewed as an aerosol generating system.

The power supply unit 111 stores power and supplies power to each component of the suction device 100 . The power supply unit 111 may be composed of, for example, a rechargeable secondary battery such as a lithium ion secondary battery. The power supply unit 111 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 unit 111 may be charged by a power transmission device that is not directly connected using wireless power transmission technology. Furthermore, the power supply unit 111 may be provided detachably from the suction device 100, or may be provided so as to be replaceable with a new power supply unit 111.

The sensor unit 112 detects various types of information about the suction device 100 and outputs the detected information to the control unit 116 . As an example, the sensor unit 112 may be configured with a pressure sensor such as a condenser microphone, a flow sensor, or a temperature sensor. In such a case, the sensor unit 112 can output information indicating that the user has performed suction to the control unit 116 when detecting a numerical value associated with the user's suction. As another example, the sensor unit 112 may be configured by an input device such as a button or switch that accepts input of information from the user. good too. In such a case, the sensor unit 112 can output information input by the user to the control unit 116 . As another example, the sensor section 112 may be configured with a temperature sensor that detects the temperature of the susceptor 161 . The temperature sensor may detect the temperature of the susceptor 161 based on the electrical resistance value of the electromagnetic induction source 162, for example. In such a case, the sensor section 112 can detect the temperature of the stick-shaped substrate 150 held by the holding section 140 based on the temperature of the susceptor 161 .

The notification unit 113 notifies the user of information. As an example, the notification unit 113 may be configured by a light-emitting device such as an LED (Light Emitting Diode). According to this, the notification unit 113 emits light in a different light emission pattern when the power supply unit 111 needs to be charged, when the power supply unit 111 is being charged, or when an abnormality occurs in the suction device 100. Can emit light. The light emission pattern here is a concept including color, timing of lighting/lighting out, and the like. The notification unit 113 may be configured by a display device that displays an image, a sound output device that outputs sound, a vibration device that vibrates, or the like, together with or instead of the light emitting device. In addition, the notification unit 113 may notify information indicating that suction by the user has become possible. Information indicating that the user can suck is notified to the user, for example, when the temperature of the stick-shaped base material 150 heated by electromagnetic induction reaches a predetermined temperature.

The storage unit 114 stores various information for the operation of the suction device 100 . The storage unit 114 is configured by, for example, a non-volatile storage medium such as flash memory. An example of the information stored in the storage unit 114 is information related to the OS (Operating System) of the suction device 100 such as control details of various components by the control unit 116 . Another example of information stored in the storage unit 114 is information related to suction by the user, such as the number of times of suction, suction time, or accumulated suction time.

The communication unit 115 is a communication interface for transmitting and receiving information between the suction device 100 and other devices. The communication unit 115 can perform communication conforming to any wired or wireless communication standard. As such a communication standard, for example, a wireless LAN (Local Area Network), a wired LAN, Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like can be adopted. As an example, the communication unit 115 may transmit information regarding suction by the user to the smartphone so that the smartphone displays information regarding suction by the user. As another example, the communication unit 115 may receive new OS information from the server in order to update the OS information stored in the storage unit 114 .

The control unit 116 functions as an arithmetic processing device and a control device, and controls the general operations within the suction device 100 according to various programs. The control unit 116 may be realized by an electronic circuit such as a CPU (Central Processing Unit) or a microprocessor. The control unit 116 may also include a ROM (Read Only Memory) for storing programs to be used, calculation parameters, etc., and a RAM (Random Access Memory) for temporarily storing parameters that change as appropriate.

Specifically, the control unit 116 may control execution of various processes related to the operation of the suction device 100 . For example, the control unit 116 controls power supply from the power supply unit 111 to other components, charging of the power supply unit 111, detection of information by the sensor unit 112, notification of information by the notification unit 113, storage of information by the storage unit 114, or Execution of processing such as reading and transmission/reception of information by the communication unit 115 may be controlled. The control unit 116 can also control the input of information to each component and the execution of processing based on the information output from each component, which is executed by the suction device 100 .

The holding part 140 has an internal space 141 and holds the stick-shaped base material 150 by accommodating a part of the stick-shaped base material 150 in the internal space 141 . The holding part 140 has an opening 142 that communicates the internal space 141 with the outside, and holds the stick-shaped substrate 150 inserted into the internal space 141 through the opening 142 . For example, the holding portion 140 may be configured in a cylindrical shape defining a columnar internal space 141 with the opening 142 and the bottom portion 143 as the bottom surface. The holding part 140 has an inner diameter smaller than the outer diameter of the stick-shaped base material 150 at least in part in the height direction of the cylindrical body, so that the stick-shaped base material 150 inserted into the internal space 141 can be held. It can be held by pressing from the outer periphery.

The holding part 140 also has a function of defining an air flow path passing through the stick-shaped base material 150 . An air inlet hole, which is an inlet for air into the channel, is arranged, for example, in the bottom portion 143 . On the other hand, the opening 142 is an air outflow hole, which is the outlet of the air from the channel.

The stick-shaped base material 150 is a stick-shaped member. The stick-type substrate 150 includes a substrate portion 151 and a mouthpiece portion 152 .

The base material portion 151 includes an aerosol source. The aerosol source is atomized by heating to produce an aerosol. The aerosol source may be, for example, a processed product derived from tobacco, or a processed product obtained by molding shredded tobacco or tobacco raw materials into a granule, sheet, or powder. Aerosol sources may also include non-tobacco-derived ingredients produced from plants other than tobacco, such as mints and herbs. As an example, the aerosol source may contain perfume ingredients. If the inhalation device 100 is a medical inhaler, the aerosol source may contain a medicament for inhalation by the patient. The aerosol source is not limited to solids and can be liquids such as, for example, polyhydric alcohols such as glycerin and propylene glycol, and water. At least part of the base material part 151 is accommodated in the internal space 141 of the holding part 140 while the stick-shaped base material 150 is held by the holding part 140 .

The mouthpiece 152 is a member held by the user when inhaling. At least part of the mouthpiece 152 protrudes from the opening 142 when the stick-shaped base material 150 is held by the holding part 140 . When the user holds the mouthpiece 152 protruding from the opening 142 and sucks, air flows into the holding section 140 through an air inlet hole (not shown). The air that has flowed in passes through the internal space 141 (that is, the substrate portion 151 ) of the holding portion 140 and reaches the user's mouth together with the aerosol generated from the substrate portion 151 .

The stick-type base material 150 also includes a susceptor 161 . The susceptor 161 can generate heat by electromagnetic induction. Susceptor 161 may be made of a conductive material. As an example, the susceptor 161 may be a piece of metal.

Specifically, the susceptor 161 may be placed in thermal proximity to the aerosol source. The susceptor 161 being thermally close to the aerosol source means that the susceptor 161 is arranged at a position where the heat generated by the susceptor 161 can be transferred to the aerosol source. For example, the susceptor 161 may be included in the substrate portion 151 along with the aerosol source such that the susceptor 161 is surrounded by the aerosol source. With such a configuration, the susceptor 161 can efficiently heat the aerosol source with the generated heat.

Note that the susceptor 161 may be provided so as to be inaccessible from the outside of the stick-shaped substrate 150 . For example, the susceptor 161 may not be arranged near the outer periphery of the stick-shaped substrate 150 but may be arranged only in the central portion of the stick-shaped substrate 150 .

The electromagnetic induction source 162 causes the susceptor 161 to generate heat by electromagnetic induction. The electromagnetic induction source 162 is supplied with an alternating current from the power supply unit 111 and can generate a varying magnetic field at a position overlapping the internal space 141 of the holding unit 140 . The electromagnetic induction source 162 can generate eddy current in the susceptor 161 and generate Joule heat in the susceptor 161 by generating a fluctuating magnetic field in a state where the stick-shaped substrate 150 is accommodated in the holding portion 140 . . Joule heat generated in the susceptor 161 can generate an aerosol by heating an aerosol source included in the stick-shaped base material 150 . A specific configuration of the electromagnetic induction source 162 will be described later.

For example, when the sensor unit 112 detects that a predetermined user input has been performed, the suction device 100 supplies power to the electromagnetic induction source 162 to induction-heat the aerosol source contained in the stick-shaped base material 150. , may generate an aerosol. When the temperature of the aerosol source reaches a predetermined temperature, the inhalation device 100 allows inhalation by the user. Thereafter, when the sensor unit 112 detects that a predetermined user input has been performed, the suction device 100 may stop supplying power to the electromagnetic induction source 162 .

As another example, the suction device 100 may supply power to the electromagnetic induction source 162 to generate aerosol while the sensor unit 112 detects that the user has suctioned.

Although FIG. 1 shows an example in which the susceptor 161 is included in the base material portion 151 of the stick-shaped base material 150, the suction device 100 is not limited to this example. For example, the holding part 140 may function as the susceptor 161 . In such a case, the suction device 100 causes the holding portion 140 to generate Joule heat by generating an eddy current in the holding portion 140 by the magnetic field generated by the electromagnetic induction source 162 . Accordingly, the suction device 100 can heat and atomize the aerosol source contained in the base material part 151 by the Joule heat generated in the holding part 140, so that the aerosol can be generated from the stick-type base material 150.

<2. Detailed Configuration of Electromagnetic Induction Source>
Next, the electromagnetic induction source 162 provided in the suction device 100 will be described in more detail with reference to FIGS. 2 to 5. FIG. FIG. 2 is a schematic perspective view of the electromagnetic induction source 162. As shown in FIG. FIG. 3 is a cross-sectional view for explaining the tubular shape of the electromagnetic induction source 162. As shown in FIG. FIG. 4 is a plan view of the one end region A1 shown in FIG. 3 as viewed from the second surface S2 side. FIG. 5 is a plan view of the other end region A2 shown in FIG. 3 as viewed from the first surface S1 side.

As shown in FIG. 2, the electromagnetic induction source 162 is provided as a solenoid coil so as to surround the stick-shaped substrate 150 housed in the holding portion 140 . For example, the electromagnetic induction source 162 may be configured by providing a spiral conductor wire 622 on one surface of a flexible substrate 621 provided in a cylindrical shape along the outer periphery of the holding portion 140 .

The conductor wire 622 constitutes a solenoid coil by being spirally provided on the side surface of the flexible substrate 621 wound in a cylindrical shape. According to this, the conductor wire 622 can generate a fluctuating magnetic field in the cylindrical inner space of the flexible substrate 621 by being supplied with an alternating current. Therefore, the electromagnetic induction source 162 can induction-heat the susceptor 161 included in the stick-shaped base material 150 arranged in the cylindrical inner space of the flexible substrate 621 by the varying magnetic field generated by the conductor wire 622 . can.

As shown in FIG. 3, such an electromagnetic induction source 162 may be configured by winding a flexible substrate 621 having a conductor wire 622 on one surface into a cylindrical shape.

The flexible substrate 621 is a flexible printed circuit board made of a thin insulating material. For example, the flexible substrate 621 may be a sheet-shaped substrate made of organic resin such as polyimide, polyetheretherketone, polyethylene terephthalate, or polyester.

The conductor line 622 is made of a conductive material such as copper, silver, or aluminum and provided on one side of the flexible substrate 621 .

As an example, the conductor wire 622 may be composed of a litz wire obtained by twisting a plurality of enameled wires. Alternatively, the conductor wire 622 may be composed of a USTC wire, which is a litz wire wound with a Tetoron (registered trademark) thread to cover it. Alternating current flows unevenly on the surface of the conductor due to the skin effect and reduces the apparent cross-sectional area of the conductor, which tends to increase the amount of heat generated from the conductor. Therefore, the conductor wire 622 is subdivided by the litz wire to reduce the influence of the skin effect, thereby reducing the heat generation amount even with the same thickness. In addition, the conductor wire 622 can be subdivided with a litz wire to increase the surface area of the conductor, thereby improving heat dissipation.

As another example, the conductor lines 622 may be composed of silver nanoparticle ink. The conductor lines 622 can be formed on the flexible substrate 621 more easily by being composed of silver nanoparticle ink. When the conductor wire 622 is made of silver nanoparticle ink, the conductor wire 622 has a substantially rectangular cross-sectional shape when cut along a cutting plane perpendicular to the extending direction.

Also, when composed of silver nanoparticle ink, the conductor line 622 may be coated with an insulating material except for both ends electrically connected to adjacent conductor lines 622 . According to this, the conductor wire 622 can prevent unintended short circuit or heat generation.

The conductor lines 622 are provided on one surface of the flexible substrate 621 as a plurality of straight lines extending in one direction parallel to each other at regular intervals. According to this, when the conductor wire 622 is wound around the flexible substrate 621 in a cylindrical shape with the axial direction intersecting the extending direction of the conductor wire 622 , one end of the conductor wire 622 is connected to the adjacent conductor wire 622 . A helical structure can be formed by connecting with the other end. Therefore, since the conductor wire 622 can function as a solenoid coil, it can generate a fluctuating magnetic field inside the tubular shape of the flexible substrate 621 by being supplied with an alternating current.

Specifically, as shown in FIGS. 3 to 5, the flexible substrate 621 has one end region A1 in which one end of the conductor wire 622 is provided, and a region A1 in which the other end of the conductor wire 622 is provided. It may be wound in a cylindrical shape by overlapping and pasting the other end region A2. The conductor lines 622 are provided on the first surface S1 of the flexible substrate 621 as a plurality of parallel straight lines extending in one direction from one end region A1 of one end of the flexible substrate 621 to the other end region A2 of the other end. good too.

The flexible substrate 621 may be wound in a cylindrical shape with the first surface S1 on which the conductor wires 622 are provided inside. According to this, the electromagnetic induction source 162 can arrange the conductor wire 622 forming the solenoid coil closer to the stick-shaped base material 150 , so that the susceptor 161 included in the stick-shaped base material 150 can be more efficiently operated. can be effectively inductively heated.

In such a case, the conductor wire 622 is provided with a connection terminal 625 that penetrates the flexible substrate 621 and is exposed on the second surface S2 opposite to the first surface S1. The connection terminal 625 connects one end of the conductor wire 622 provided on the first surface S1 of the one end region A1 and the other end of the adjacent conductor wire 622 provided on the first surface S1 of the other end region A2. can be electrically connected to the ends. According to this, by winding the flexible substrate 621 in a cylindrical shape, a plurality of conductor wires 622 provided parallel to each other at equal intervals can be connected as one spiral coil.

Also, one end of the conductor wire 622 and the other end of the adjacent conductor wire 622 may be electrically connected via a connector. A connector is a component for electrically connecting electric wires using a plug, a jack, or the like, and is provided on the second surface S2 in addition to the connection terminal 625 or instead of the connection terminal 625 . When the conductor wires 622 are electrically connected via a connector, the electromagnetic induction source 162 further reduces the contact resistance generated at the contact points between the conductor wires 622 compared to when they are connected by soldering or crimping. be able to. In addition, since the electromagnetic induction source 162 can electrically connect the conductor wires 622 more reliably, generation of sparks at contact points between the conductor wires 622 or misalignment of connection between the conductor wires 622 can be prevented. Suppression is also possible.

According to the above configuration, the electromagnetic induction source 162 can simply and compactly form a solenoid coil that surrounds the outer periphery of the holding portion 140 with the conductor wire 622 . Therefore, the suction device 100 with the electromagnetic induction source 162 can be more easily miniaturized.

One end of the conductor wire 622 and the other end of the adjacent conductor wire 622 may be electrically connected at the end surfaces of the ends. In such a case, the flexible substrate 621 has a one end region A1 provided with one end of the conductor wire 622 and another end region A2 provided with the other end of the conductor wire 622 overlapping each other. First, the end face of the one end side region A1 and the end face of the other end side region A2 are connected. According to this, the conductor wire 622 is electrically connected to the end face of one end of the conductor wire 622 and the end face of the other end of the adjacent conductor wire 622, thereby forming a single spiral. A coil can be configured.

<3. Variation>
Next, a modification of the electromagnetic induction source 162 included in the suction device 100 will be described with reference to FIG. FIG. 6 is a cross-sectional view illustrating a cylindrical shape of an electromagnetic induction source 162 according to a modification.

As shown in FIG. 6, in the electromagnetic induction source 162 according to the modified example, a shield layer 623 that shields the magnetic field is further provided outside the cylindrical shape of the flexible substrate 621 rather than the conductor wire 622 .

The shield layer 623 is made of a soft magnetic material with a high relative magnetic permeability, and shields the magnetic field generated by the solenoid coil of the conductor wire 622 . Shield layer 623 may be composed of, for example, soft iron, silicon steel, or soft ferrite. According to this, since the shield layer 623 can absorb the magnetic flux generated by the solenoid coil of the conductor wire 622, it shields the magnetic field generated by the conductor wire 622 from leaking to the outside of the electromagnetic induction source 162. be able to. Therefore, the shield layer 623 can reduce the possibility that the magnetic field generated by the conductor wire 622 affects other components of the suction device 100 such as the control unit 116 .

However, the shield layer 623 may generate heat by absorbing the magnetic flux generated by the conductor wire 622 . Therefore, the shield layer 623 may be provided on the second surface S2 opposite to the first surface S1 on which the conductor wires 622 are provided so as not to come into contact with the conductor wires 622 . According to this, the shield layer 623 can prevent the heat of the shield layer 623 itself from hindering heat dissipation from the conductor wire 622 .
