Description of Embodiments

Hereinafter, a suitable embodiment of the present invention will be described in detail with reference to the attached drawings. In the present specification and the drawings, structural elements having substantially identical functional configurations are denoted by identical signs, and duplicate description is omitted.

«1. General Configuration Example of Inhaler Device»

An inhaler device generates a material to be inhaled by a user. In the example described below, the material generated by the inhaler device is aerosol. Alternatively, the material generated by the inhaler device may be gas. In the following description, an action of a user inhaling a material generated by the inhaler device is also simply referred to as "inhalation" or "puff". Each configuration example of the inhaler device will be described below.
The inhaler device according to the present configuration example generates aerosol by heating an aerosol source as liquid and heating a substrate that includes an aerosol source. The present configuration example will be described below with reference to FIG. 1.
FIG. 1 is a schematic diagram schematically illustrating a configuration example of an inhaler device according to one embodiment of the present invention. As illustrated in FIG. 1, an inhaler device 100 according to the present configuration example includes a power supply 111, a sensor 112, a notifier 113, a memory 114, a communicator 115, a controller 116, a liquid guide 122, a liquid storage 123, a heater 40A, a heater 40B, a chamber 50, and a heat insulator 70. In addition, an airflow path 180 is defined in the inhaler device 100.
The heater 40B, the liquid guide 122, and the liquid storage 123 are included in a cartridge 120. The cartridge 120 is detachable from the inhaler device 100. Typically, inhalation is performed by a user in a state in which the cartridge 120 is mounted on the inhaler device 100 and in which a stick substrate 150 is received by the chamber 50. Hereinafter, structural elements will be described in order.
The power supply 111 stores electric power. Then, the power supply 111 supplies electric power to structural elements of the inhaler device 100. The power supply 111 may be, for example, a rechargeable battery such as a lithium ion secondary battery. The power supply 111 may be charged by being connected to an external power supply by a USB (Universal Serial Bus) cable or the like. The power supply 111 may be charged in a state of not being connected to a device on the power transmission side by a wireless power transmission technology. In addition, only the power supply 111 may be detachable from the inhaler device 100 and may be replaceable with a new power supply 111.
The sensor 112 detects various items of information regarding the inhaler device 100. Then, the sensor 112 outputs the detected information to the controller 116. In one example, the sensor 112 is a pressure sensor such as a microphone condenser, a flow sensor, or a temperature sensor. When the sensor 112 detects a numerical value due to inhalation by a user, the sensor 112 outputs information indicating that inhalation is performed by a user to the controller 116. In another example, the sensor 112 is an input device, such as a button or a switch, that receives an information input from the user. In particular, the sensor 112 can include a button for instructing start/stop of generation of aerosol. The sensor 112 outputs information that is input by the user to the controller 116. In another example, the sensor 112 is a temperature sensor that detects the temperature of the heater 40A. The temperature sensor detects the temperature of the heater 40A on the basis of, for example, the value of electric resistance of a conducting track of the heater 40A. The sensor 112 may detect the temperature of the stick substrate 150 received by the chamber 50 on the basis of the temperature of the heater 40A.
The notifier 113 provides information to the user. In one example, the notifier 113 is a light-emitting device such as an LED (Light Emitting Diode). In this case, the notifier 113 emits light in light-emission patterns that are different for each of cases such as a case where the power supply 111 is in a state of requiring charging, a case where the power supply 111 is being charged, and a case where an abnormality has occurred in the inhaler device 100. The light-emission patterns described here are concepts including colors, the timing of turning on/off, and the like. The notifier 113 may be, in addition to or instead of the light-emitting device, a display device that displays an image, a sound output device that outputs sound, a vibration device that vibrates, or the like. In addition, the notifier 113 may provide information indicating that inhalation by a user is possible. The information indicating that inhalation by a user is possible is provided when the temperature of the stick substrate 150 heated by the heater 40A has reached a predetermined temperature.
The memory 114 stores various items of information for operation of the inhaler device 100. The memory 114 is, for example, a non-volatile storage medium such as a flash memory. One example of the information stored in the memory 114 is information, such as the content of control of various structural elements by the controller 116, on the OS (Operating System) of the inhaler device 100. Another example of the information stored in the memory 114 is information, such as the number of times of inhalation, the inhalation time, and the accumulated inhalation time period, on inhalation by the user.
The communicator 115 is a communication interface for transmitting and receiving information between the inhaler device 100 and the other devices. The communicator 115 performs communication in conformity with any wired or wireless communication standard. As such communication standard, for example, a wireless LAN (Local Area Network), a wired LAN, Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like is employable. In one example, the communicator 115 transmits information on inhalation by a user to a smartphone to cause the smartphone to display the information on the inhalation by the user. In another example, the communicator 115 receives information on new OS from a server to update OS information stored in the memory 114.
The controller 116 functions as an arithmetic processing unit and a control circuit, and controls the overall operations of the inhaler device 100 in accordance with various programs. The controller 116 is realized by, for example, an electronic circuit such as a CPU (Central Processing Unit) and a microprocessor. In addition, the controller 116 may include a ROM (Read Only Memory) that stores programs, arithmetic parameters, and the like that are to be used, and a RAM (Random Access Memory) that temporarily stores parameters and the like that change, as appropriate. The inhaler device 100 executes various processes on the basis of control by the controller 116. Examples of processes controlled by the controller 116 include supplying of electric power from the power supply 111 to the other structural elements, charge of the power supply 111, detection of information by the sensor 112, notice of information by the notifier 113, storing and reading-out of information by the memory 114, and transmission and reception of information by the communicator 115. The controller 116 also controls the other processes, such as input of information to structural elements and processes based on information output from structural elements, to be executed by the inhaler device 100.
The liquid storage 123 stores an aerosol source. The aerosol source is atomized by being heated to generate aerosol. The aerosol source is, for example, liquid such as polyhydric alcohol or water. Examples of the polyhydric alcohol include glycerine and propylene glycol. The aerosol source may further include a tobacco raw material or a tobacco-raw-material-derived extract that releases a flavor component by being heated. The aerosol source may further include nicotine. For the inhaler device 100 that is a medical inhaler such as a nebulizer, the aerosol source may include a medicine that is to be inhaled by a patient.
The liquid guide 122 guides the aerosol source, which is liquid stored in the liquid storage 123, from the liquid storage 123 and holds the aerosol source. The liquid guide 122 is, for example, a wick formed by twining a fiber material such as glass fiber or a porous material such as porous ceramic. The liquid guide 122 is in liquid-communication with the liquid storage 123. The aerosol source stored in the liquid storage 123 thus spreads throughout the entirety of the liquid guide 122 due to the capillary action.
The heater 40B heats the aerosol source to atomize the aerosol source and generate the aerosol. The heater 40B is formed of any material such as metal or polyimide into any shape such as a coil shape, a film shape, or a blade shape. The heater 40B is disposed close to the liquid guide 122. In the example illustrated in FIG. 1, the heater 40B is constituted by a coil made of metal and is wound around the liquid guide 122. Therefore, when the heater 40B produces heat, the aerosol source held by the liquid guide 122 is heated and atomized to generate the aerosol. The heater 40B produces heat when receiving electric power from the power supply 111. In one example, the electric power may be supplied to generate the aerosol during a period in which the sensor 112 detects inhalation performed by a user. In another example, the electric power may be supplied to generate the aerosol in response to the sensor 112 detecting that a predetermined user input (for example, pressing of a button for instructing start/stop of generation of aerosol) is performed. Subsequently, the supply of the electric power may be stopped in response to the sensor 112 detecting that a predetermined user input (for example, re-pressing of the button for instructing start/stop of generation of aerosol) is performed.
The chamber 50 receives the stick substrate 150 inserted through a first opening 52. For example, the chamber 50 is a tubular body having the first opening 52 and a bottom 54 as bottom surfaces, and defines a pillar-shaped internal space 80. The bottom 54 of the chamber 50 is provided with a second opening 56. The chamber 50 also has a function of defining a flow path of air that passes through the stick substrate 150. An inlet of the air into the flow path is the second opening 56. An outlet of the air from the flow path is the first opening 52.
The stick substrate 150 is a stick-type member. The stick substrate 150 includes a substrate 151 and an inhalation port 152.
The substrate 151 includes an aerosol source. The aerosol source is atomized by being heated to generate aerosol. The aerosol source may be, for example, a tobacco-derived product, such as a product obtained by molding shredded tobacco or a tobacco raw material into a particle shape, a sheet shape, or a power shape. The aerosol source may include a non-tobacco-derived product made from plants (for example, mint, herbs, and the like) other than tobacco. In one example, the aerosol source may include a flavor component such as menthol. For the inhaler device 100 that is a medical inhaler, the aerosol source may include a medicine that is to be inhaled by a patient. The aerosol source is not limited to a solid and may be, for example, liquid such as polyhydric alcohol or water. Examples of the polyhydric alcohol include glycerine and propylene glycol. At least a portion of the substrate 151 is accommodated in the internal space 80 of the chamber 50 in a state in which the stick substrate 150 is received by the chamber 50.
The inhalation port 152 is a member to be held in the mouth of a user during inhalation. At least a portion of the inhalation port 152 projects from the first opening 52 in the state in which the stick substrate 150 is received by the chamber 50. When the user holds the inhalation port 152 projecting from the first opening 52 in the mouth of the user and inhales, air flows through the second opening 56 into the internal space 80 of the chamber 50. The flowed-in air passes through the internal space 80 of the chamber 50, more specifically, passes through the substrate 151 and reaches, together with aerosol generated from the substrate 151, the inside of the mouth of the user
The heater 40A heats the aerosol source to atomize the aerosol source and generate aerosol. The heater 40A is constituted by any material such as metal or polyimide. For example, the heater 40A is formed in a film shape and disposed to cover the outer circumference of the chamber 50. When the heater 40A produces heat, the aerosol source included in the stick substrate 150 is heated through the outer circumference of the stick substrate 150 and atomized, and aerosol is generated. The heater 40A produces heat when receiving electric power from the power supply 111. In one example, electric power may be supplied to generate aerosol in response to the sensor 112 detecting that a predetermined user input is performed. When the temperature of the stick substrate 150 heated by the heater 40A reaches a predetermined temperature, inhalation by a user becomes possible. Subsequently, electric power supply may be stopped in response to the sensor 112 detecting that a predetermined user input is performed. In another example, electric power is supplied to generate aerosol during a period in which the sensor 112 detects that inhalation by a user is performed.
The heat insulator 70 prevents heat from transferring from the heater 40A to the other structural elements of the inhaler device 100. The heat insulator 70 is disposed to cover at least the outer circumference of the heater 40A. For example, the heat insulator 70 is constituted by a vacuum heat insulator, an aerogel heat insulator, or the like. The vacuum heat insulator is, for example, an insulator in which heat conduction by gas is made to be as close as possible to zero by wrapping, for example, glass wool and silica (silicon powder) with a resin film into a high-vacuum state.
The airflow path 180 is a flow path of air that is to be introduced into the internal space 80 of the chamber 50. The airflow path 180 can have, at both ends, a tubular structure having an air inlet hole 181 that is an inlet of air into the airflow path 180 and the bottom 54 of the chamber 50. The second opening 56 provided in the bottom 54 of the chamber 50 is an outlet of air from the airflow path 180. That is, the internal space 80 of the chamber 50 is in air-communication with the airflow path 180 through the second opening 56 of the chamber 50. Along with inhalation by a user, air flows into the airflow path 180 through the air inlet hole 181, and the air flows out to the internal space 80 of the chamber 50 through the second opening 56. The liquid guide 122 and the heater 40B are disposed at intermediate positions in the airflow path 180. The aerosol generated by the heater 40B mixes with the air that has flowed in through the air inlet hole 181. Next, along with inhalation by the user, a mixture fluid of the aerosol and the air is conveyed to the internal space 80 of the chamber 50 via the second opening 56 as indicated by an airflow 190. The mixture fluid of the aerosol and the air conveyed to the internal space 80 of the chamber 50 reaches the inside of the mouth of the user together with the aerosol generated by the heater 40A.

- Modifications -

A configuration example of the inhaler device 100 has been described above. Needless to say, the configuration of the inhaler device 100 is not limited to the aforementioned configuration. As the configuration of the inhaler device 100, various configurations presented below as examples are employable.
In one example, aerosol may be generated by vibration or induction heating, instead of heating by the heater 40B.
To generate aerosol by vibration, the inhaler device 100 includes a vibrator instead of the heater 40B. For example, the vibrator is constituted by a tabular member including a piezoceramic that functions as an ultrasonic vibrator. When the vibrator vibrates, the aerosol source guided to a surface of the vibrator by the liquid guide 122 is atomized by ultrasonic waves generated along with the vibration of the vibrator, and aerosol is generated.
To generate aerosol by induction heating, the inhaler device 100 includes a susceptor and an electromagnetic induction source instead of the heater 40B. The susceptor produces heat by electromagnetic induction. The susceptor is constituted by a conductive material such as metal. The susceptor is disposed close to the liquid guide 122. For example, the susceptor is constituted by a conductive wire made of metal and is wound around the liquid guide 122. The electromagnetic induction source causes the susceptor to produce heat by electromagnetic induction. The electromagnetic induction source is constituted by, for example, a coiled conductive wire. When alternating current is supplied from the power supply 111 to the electromagnetic induction source, the electromagnetic induction source generates a magnetic field. The electromagnetic induction source is disposed at a position where the susceptor overlaps the generated magnetic field. Therefore, when a magnetic field is generated, eddy current is generated in the susceptor, and Joule heat is generated. The aerosol source held by the liquid guide 122 is heated by the Joule heat and atomized, and aerosol is generated.
In another example, aerosol may be generated by induction heating, instead of heating by the heater 40A.
In this case, the stick substrate 150 further includes a susceptor. The susceptor produces heat by electromagnetic induction. The susceptor is constituted by a conductive material such as metal. In one example, the susceptor is a metal piece. The susceptor is disposed close to the aerosol source. For example, the susceptor is included in the substrate 151 of the stick substrate 150.
The inhaler device 100 includes an electromagnetic induction source, instead of the heater 40A. The electromagnetic induction source is constituted by, for example, a coiled conductive wire and is disposed to be wound around the outer circumference of the chamber 50. When receiving alternating current from the power supply 111, the electromagnetic induction source generates a magnetic field. The electromagnetic induction source is disposed at a position where the internal space 80 of the chamber 50 overlaps the generated magnetic field. Therefore, when a magnetic field is generated in a state in which the stick substrate 150 is received by the chamber 50, eddy current is generated in the susceptor, and Joule heat is generated. Then, the aerosol source included in the stick substrate 150 is heated and atomized by the Joule heat, and aerosol is generated.
In another example, the heater 40A may be formed in a blade shape and disposed so as to project from the bottom 54 of the chamber 50 into the internal space 80. In this case, the blade-shaped heater 40A is inserted into the substrate 151 of the stick substrate 150 and heats the substrate 151 of the stick substrate 150 from the inside. In another example, the heater 40A may be disposed so as to cover the bottom 54 of the chamber 50. The heater 40A may be configured as a combination of two or more of a heater that covers the outer circumference of the chamber 50, a blade-shaped heater, and a heater that covers the bottom 54 of the chamber 50.
In another example, the chamber 50 may include an opening/closing mechanism, such as a hinge, that opens and closes a portion of the outer shell that forms the internal space 80. The chamber 50 may hold the stick substrate 150 inserted into the internal space 80 by opening and closing the outer shell. In this case, the heater 40A may be provided at the portion of the chamber 50 at which the stick substrate 150 is held and may heat the stick substrate 150 while pressing the stick substrate 150.
The means for generating aerosol is not limited to heating. For example, the means for generating aerosol may be vibration atomization or induction heating.

- Supplementary Note -

The heater 40A is one example of the first generator that generates aerosol by using the first substrate. The stick substrate 150 is one example of the first substrate containing an aerosol source. Hereinafter, the heater 40A is also referred to as the stick-side heater 40A. The heater 40B is one example of the second generator that generates aerosol by using the second substrate. The cartridge 120 is one example of the second substrate containing an aerosol source that is liquid. Hereinafter, the heater 40B is also referred to as the cartridge-side heater 40B.
The aerosol generated by the stick-side heater 40A is also referred to as the stick-side aerosol. Meanwhile, the aerosol generated by the cartridge-side heater 40B is also referred to as the cartridge-side aerosol. The stick-side aerosol and the cartridge-side aerosol are also simply collectively referred to as the aerosol when not required to be particularly distinguished from each other.

«2. Technical Problems»

As described above with reference to FIG. 1, the inhaler device 100 uses the two substrates of the cartridge 120 and the stick substrate 150 together. Therefore, the user can inhale and taste mixture aerosol in which the stick-side aerosol and the cartridge-side aerosol are mixed. The inhaler device 100 that generates mixture aerosol by, as described above, using two types of substrates together is also referred to as a hybrid-type inhaler device.
Here, it is considered that the user may feel like tasting only the stick-side aerosol, feel like tasting only the cartridge-side aerosol, or feel like tasting the mixture aerosol. Thus, there is provided in the present embodiment a mechanism capable of switching the operation of the inhaler device 100 in accordance with these demands. That is, the inhaler device 100 according to the present embodiment is capable of selectively generating the stick-side aerosol and the cartridge-side aerosol.

(1) Detailed Configuration Example of Inhaler Device 100

Hereinafter, a detailed configuration example of the inhaler device 100 will be described with reference to FIG. 2 to FIG. 7.
FIG. 2 illustrates one example of the exterior configuration of the inhaler device 100 according to the present embodiment. As illustrated in FIG. 2, the inhaler device 100 may be formed in a columnar shape. A top surface 102 of the inhaler device 100 is provided with the first opening 52, a first air inlet hole 181A, and a second air inlet hole 181B. A slider 184 is disposed to be slidable on the top surface 102 of the inhaler device 100. Depending on the position of the slider 184, the first opening 52, the first air inlet hole 181A, and the second air inlet hole 181B are opened and closed. Here, closing the holes of the first opening 52 and the like means that the holes are covered by the slider 184 and make inflow and outflow of air through the holes difficult. Meanwhile, opening the holes of the first opening 52 and the like means that the holes are exposed and enable inflow and outflow of air through the holes. Such a configuration makes it possible to easily control inflow and outflow of air with respect to the inhaler device 100.
FIG. 3 is a top view of the inhaler device 100 with the first opening 52 closed by the slider 184. Meanwhile, the first air inlet hole 181A and the second air inlet hole 181B are open. FIG. 4 is a top view of the inhaler device 100 with the second air inlet hole 181B closed by the slider 184. Meanwhile, the first opening 52 and the first air inlet hole 181A are open. FIG. 5 is a top view of the inhaler device 100 with the first air inlet hole 181A closed by the slider 184. Meanwhile, the first opening 52 and the second air inlet hole 181B are open. FIG. 6 roughly illustrates one example of the internal configuration of the inhaler device 100 in which the stick substrate 150 is received in the state illustrated in FIG. 4. FIG. 7 roughly illustrates one example of the internal configuration of the inhaler device 100 in which the stick substrate 150 is received in the state illustrated in FIG. 5.
As illustrated in FIG. 3 to FIG. 5, the slider 184 rotates on the top surface 102 of the inhaler device 100 with the rotational axis at the center of the top surface 102 of the inhaler device 100. The user can open and close the first opening 52, the first air inlet hole 181A, and the second air inlet hole 181B by sliding the slider 184.
As illustrated in FIG. 6 and FIG. 7, the chamber 50 receives the stick substrate 150. In this state, the stick-side heater 40A heats the stick substrate 150 to generate the stick-side aerosol. The second opening 56 is disposed at a position where the second opening 56 is in communication with an end surface (that is, an end surface of the substrate 151) of the stick substrate 150 inside the chamber 50 in a state in which the chamber 50 receives the stick substrate 150. Therefore, when the user holds the stick substrate 150 in the mouth and inhales, the air that has flowed into the chamber 50 through the second opening 56 flows into the inside of the stick substrate 150 from the end portion of the stick substrate 150 inside the chamber 50. The air that has flowed into the inside of the stick substrate 150 is then mixed with the stick-side aerosol in the process of being conveyed via the inside of the stick substrate 150, and reaches the inside of the mouth of the user from an end surface (that is, an end surface of the inhalation port 152) of the stick substrate 150 outside the chamber 50.
As illustrated in FIG. 6, a first airflow path 180A through which the first air inlet hole 181A and the second opening 56 are in air-communication with each other is formed as one airflow path 180 in the inhaler device 100. The air that has flowed in through the first air inlet hole 181A is conveyed through the first airflow path 180A and flows into the internal space 80 of the chamber 50 through the second opening 56. Therefore, when the user adds the stick substrate 150 and inhales, air is conveyed along an airflow 190A and reaches, together with the stick-side aerosol, the inside of the mouth of the user
As illustrated in FIG. 7, a second airflow path 180B through which the second air inlet hole 181B and the second opening 56 are in air-communication with each other is formed as one airflow path 180 in the inhaler device 100. The cartridge-side heater 40B is disposed at an intermediate position in the second airflow path 180B. When the cartridge-side heater 40B heats the aerosol source introduced to the liquid guide 122 from the liquid storage 123, the cartridge-side aerosol is generated. The air that has flowed in through the second air inlet hole 181B is mixed with the cartridge-side aerosol in the middle of being conveyed through the second airflow path 180B, flows into the internal space 80 of the chamber 50 through the second opening 56, and is further mixed with the stick-side aerosol. Therefore, when the user holds the stick substrate 150 in the mouth and inhales, air is conveyed along an airflow 190B and reaches, together with the mixture aerosol, the inside of the mouth of the user
Here, as illustrated in FIG. 6 and FIG. 7, a portion of the first airflow path 180A near the second opening 56 and a portion of the second airflow path 180B near the second opening 56 overlap each other. The cartridge-side heater 40B is disposed, in the second airflow path 180B, at a position that does not overlap the first airflow path 180A. In addition, the liquid guide 122 is also disposed, in the second airflow path 180B, at a position that does not overlap the first airflow path 180A. In other words, the cartridge-side heater 40B and the liquid guide 122 are not disposed in the first airflow path 180A. Such a configuration prevents a flavor of the aerosol source guided by the liquid guide 122 from being added to the air conveyed along the airflow 190A. Consequently, when inhaling with the first airflow path 180A open and the second airflow path 180B closed, the user can taste the pure flavor of the stick-side aerosol whose flavor is not deteriorated due to the cartridge-side aerosol.
The slider 184 is one example of an opening/closing part that opens and closes each of the first airflow path 180A and the second airflow path 180B. As illustrated in FIG. 6, the slider 184 can open the first airflow path 180A and close the second airflow path 180B by closing the second air inlet hole 181B. As illustrated in FIG. 7, the slider 184 can open the second airflow path 180B and close the first airflow path 180A by closing the first air inlet hole 181A.
The sensor 112 further includes a hall sensor that detects the position of the slider 184. The hall sensor is a contactless magnetic sensor that changes a magnetic field into an electric signal by utilizing a hall effect. In one example, a magnet is incorporated in the slider 184, and the top surface 102 of the inhaler device 100 is provided with a hall element. The hall sensor can detect the position of the slider 184 on the basis of an output from the hall element by previously storing the correspondence between the position of the slider 184 and an electric signal output from the hall element. On the basis of the position of the slider 184 detected by the hall sensor, the controller 116 determines the open/close state of each of the first airflow path 180A and the second airflow path 180B. For example, when the position of the slider 184 is the position illustrated in FIG. 4, the controller 116 determines that the first airflow path 180A is open and the second airflow path 180B is closed. When the position of the slider 184 is the position illustrated in FIG. 5, the controller 116 determines that the first airflow path 180A is closed and the second airflow path 180B is open.
As illustrated in FIG. 6 and FIG. 7, the second airflow path 180B is shorter than the first airflow path 180A. Such a configuration can suppress the temperature of the cartridge-side aerosol generated by the cartridge-side heater 40B from decreasing during convey to the chamber 50. Therefore, it is possible to prevent the cartridge-side aerosol from condensing before conveyed to the chamber 50. In addition, since the cartridge-side aerosol is conveyed to the chamber 50 while maintaining the high temperature of the cartridge-side aerosol, it is possible to suppress the temperature of the stick substrate 150 from decreasing.
As illustrated in FIG. 6 and FIG. 7, a liquid reservoir 186 is provided at a position where the liquid reservoir 186 is in air-communication with the first airflow path 180A and the second airflow path 180B. In the liquid reservoir 186, liquid generated as a result of aerosol condensing in the inhaler device 100 can be accumulated. The liquid reservoir 186 is provided at a position facing the first opening 52 with the second opening 56 interposed therebetween in the insertion direction of the stick substrate 150. It is thus possible to cause the liquid generated as a result of aerosol condensing in the chamber 50 to flow down to the liquid reservoir 186 through the second opening 56. It is also possible to cause liquid generated as a result of the cartridge-side aerosol condensing before reaching the chamber 50 to flow down to the liquid reservoir 186 by following the second airflow path 180B.
A draining mechanism 160 is a mechanism for draining the liquid accumulated in the liquid reservoir 186 to the outside of the inhaler device 100. The draining mechanism 160 includes a drain hole 162 provided in the inhaler device 100, an opening/closing valve 164 that opens and closes the drain hole 162, and a drain path 166 through which the drain hole 162 and the liquid reservoir 186 are in communication with each other. The aerosol as liquid accumulated in the liquid reservoir 186 can be drained to the outside of the inhaler device 100 through the drain hole 162 via the drain path 166 by tilting the inhaler device 100 such that the drain hole 162 is placed on the lower side in a state in which the drain hole 162 is opened by the opening/closing valve 164. Such a configuration can prevent the condensed liquid from remaining in the airflow path 180. It is thus possible to improve heating efficiency while reducing risk of malfunctions.

(2) Switching Between Stick Heating Type and Hybrid Type

The controller 116 controls the operation of the stick-side heater 40A and the cartridge-side heater 40B on the basis of the open/close state of each of the first airflow path 180A and the second airflow path 180B. As described below in detail, such a configuration enables the inhaler device 100 to selectively generate each of the stick-side aerosol and the cartridge-side aerosol.
In detail, the controller 116 controls permission/prohibition of electric power supply to each of the stick-side heater 40A and the cartridge-side heater 40B on the basis of the open/close state of each of the first airflow path 180A and the second airflow path 180B. When a predetermined condition is satisfied, the controller 116 executes electric power supply to the heater 40 for which electric power supply is permitted. Meanwhile, the controller 116 does not execute electric power supply to the heater 40 for which electric power supply is prohibited. Such a configuration makes it possible to selectively execute heating by each of the stick-side heater 40A and heating by the cartridge-side heater 40B.
When electric power supply to the stick-side heater 40A is permitted, the controller 116 controls continuous electric power supply to the stick-side heater 40A to be started from a timing when a predetermined input is detected. One example of the predetermined input is a user operation, such as pressing down of a button, instructing a start of heating of the stick substrate 150. Meanwhile, when electric power supply to the stick-side heater 40A is prohibited, the controller 116 controls electric power supply to the stick-side heater 40A not to be started even when a predetermined input is detected. The stick substrate 150 can continuously generate a sufficient amount of aerosol by being continuously heated by the stick-side heater 40A to increase the temperature of the stick substrate 150. Therefore, such a configuration makes is possible to control whether to generate the stick-side aerosol in accordance with permission/prohibition of electric power supply to the stick-side heater 40A.
When electric power supply to the cartridge-side heater 40B is permitted, the controller 116 controls electric power to be supplied to the cartridge-side heater 40B at a timing when inhalation performed by the user is detected. Meanwhile, when electric power supply to the cartridge-side heater 40B is prohibited, the controller 116 controls electric power not to be supplied to the cartridge-side heater 40B even when inhalation performed by the user is detected. The aerosol source introduced to the liquid guide 122 from the liquid storage 123 can generate the cartridge-side aerosol by being instantaneously heated by the cartridge-side heater 40B to thereby sufficiently increase the temperature of the aerosol source. Such a configuration thus makes it possible to control whether to generate the cartridge-side aerosol in accordance with permission/prohibition of electric power supply to the cartridge-side heater 40B.
As illustrated in FIG. 6, when the first airflow path 180A is open while the second airflow path 180B is closed, the controller 116 permits electric power supply to the stick-side heater 40A and prohibits electric power supply to the cartridge-side heater 40B. In such a configuration, the cartridge-side aerosol is not generated. Thus, the user can inhale only the stick-side aerosol together with the air conveyed along the airflow 190A. That is, the inhaler device 100 can operate as the inhaler device 100 of a stick heating type that generates only the stick-side aerosol.
As illustrated in FIG. 7, when the second airflow path 180B is open while the first airflow path 180A is closed, the controller 116 permits electric power supply to both the stick-side heater 40A and the cartridge-side heater 40B. In such a configuration, both the cartridge-side aerosol and the stick-side aerosol are generated. Thus, the user can inhale mixture aerosol together with the air conveyed along the airflow 190B. That is, the inhaler device 100 can operate as the inhaler device 100 of a hybrid type that generates mixture aerosol.
Depending on the position of the slider 184, there is a likelihood of at least part of both the first airflow path 180A and the second airflow path 180B being open. In such a case, the controller 116 prohibits electric power supply to both the stick-side heater 40A and the cartridge-side heater 40B. Such a configuration can prevent erroneous operation.
The controller 116 permits electric power supply to the stick-side heater 40A when the stick substrate 150 is received by the chamber 50 and prohibits electric power supply to the stick-side heater 40A when the stick substrate 150 is not received by the chamber 50. Such a configuration can prevent accidental heating. The sensor 112 further includes a sensor for detecting whether the stick substrate 150 is received by the chamber 50.
As described above, the inhaler device 100 according to the present embodiment can operate in accordance with the open/close state of the airflow path 180 by switching to one of the stick heating type and the hybrid type. Therefore, the user can easily taste the stick-side aerosol or the mixture aerosol. Thus, it is possible to improve the quality of experience using the inhaler device 100.

(3) Switching to Cartridge Type

The inhaler device 100 may operate as the inhaler device 100 of a cartridge heating type that generates only the cartridge-side aerosol. This point will be described in detail with reference to FIG. 8 to FIG. 10.
FIG. 8 roughly illustrates one example of the internal configuration of the inhaler device 100 in which the stick substrate 150 is not received in the state illustrated in FIG. 5. As in the example illustrated in FIG. 8, when the second airflow path 180B is open with the stick substrate 150 not received by the chamber 50, the controller 116 prohibits electric power supply to the stick-side heater 40A and permits electric power supply to the cartridge-side heater 40B. The controller 116 controls electric power to be supplied to the cartridge-side heater 40B at a timing when inhalation performed by the user is detected. Consequently, the cartridge-side aerosol is generated. The user can taste only the cartridge-side aerosol by, for example, inhaling while touching the first opening 52 with the mouth of the user. That is, the inhaler device 100 can operate as the cartridge heating type.
A mouthpiece may be attached to the inhaler device 100 optionally when the inhaler device 100 operates as the cartridge heating type. FIG. 9 roughly illustrates one example of the internal configuration of the inhaler device 100 to which a mouthpiece is attached in the state illustrated in FIG. 5. In the example illustrated in FIG. 9, the first air inlet hole 181A is closed by the slider 184, and the second airflow path 180B is open. In addition, a mouthpiece 168 is attached in the vicinity of the first opening 52.
When the second airflow path 180B is open while the stick substrate 150 is not received by the chamber 50 with the mouthpiece 168 attached, the controller 116 prohibits electric power supply to the stick-side heater 40A and permits electric power supply to the cartridge-side heater 40B. The controller 116 controls electric power to be supplied to the cartridge-side heater 40B at a timing when inhalation performed by the user is detected. Consequently, the cartridge-side aerosol is generated. The user can taste only the cartridge-side aerosol by inhaling while holding the mouthpiece 168 in the mouth. Such a configuration enables the user to comfortably inhale the aerosol compared with when inhaling while touching the first opening 52 with the mouth.
When the second airflow path 180B is open while the stick substrate 150 is not received by the chamber 50 with the mouthpiece 168 not attached, the controller 116 may prohibit electric power supply to the stick-side heater 40A and the cartridge-side heater 40B. In such a configuration, the inhaler device 100 can be limited to operate as the cartridge heating type when the mouthpiece 168 is attached.
FIG. 10 illustrates one example of the configuration of the chamber 50. As illustrated in FIG. 10, the chamber 50 has a holder 60 and a non-holder 62. The holder 60 holds the stick substrate 150 inserted through the first opening 52. In one example, the holder 60 is configured such that the inside diameter of at least a portion thereof is shorter than the outside diameter of the stick substrate 150, and holds the stick substrate 150 by pressing the stick substrate 150 from the outer circumference. The non-holder 62 is disposed closer than the holder 60 to the first opening 52. In one example, the non-holder 62 is configured such that the inside diameter thereof is longer than the outside diameter of the stick substrate 150, and is not in contact with the stick substrate 150 even in a state in which the stick substrate 150 is held by the holder 60. As illustrated in FIG. 10, the mouthpiece 168 inserted through the first opening 52 is attached to the inner side of the non-holder 62. In detail, the mouthpiece 168 is attached such that the outer surface of a lower end portion of the mouthpiece 168 is in close contact with the inner surface of the non-holder 62. The inside diameter of the non-holder 62 is larger than the inside diameter of the holder 60. Due to such a configuration, a step 64 formed by a difference in inside diameter is formed at a boundary part between the holder 60 and the non-holder 62. Consequently, it is possible to position the mouthpiece 168 properly by using the step 64.
A sensor 170 for detecting whether the mouthpiece 168 is attached is disposed at the non-holder 62. In one example, the sensor 170 may be a proximity sensor that detects an object in proximity. Such a configuration makes it possible to perform switching to the cartridge heating type automatically. The sensor 170 may also serve as a sensor for detecting whether the stick substrate 150 is received by the chamber 50. In one example, the sensor 170 configured as a proximity sensor may detect attachment of the mouthpiece 168 or reception of the stick substrate 150 on the basis of the distance to an object in proximity.
As illustrated in FIG. 10, the stick-side heater 40A is disposed at the outer surface of the holder 60. For example, the stick-side heater 40A is disposed over the entire surface of the outer circumference of the holder 60 so as to surround the outer circumference of the holder 60. Such a configuration makes it possible to efficiently heat the stick substrate 150 held by the holder 60. In addition, with the stick-side heater 40A being not disposed at the non-holder 62, it is possible to prevent the mouthpiece 168 from deteriorating due to residual heat of the stick-side heater 40A when the mouthpiece 168 is attached to the non-holder 62.
As described above, the inhaler device 100 according to the present embodiment is capable of operating by switching to one of the cartridge heating type, the stick heating type, and the hybrid type. Therefore, the user can easily taste one of the cartridge-side aerosol, the stick-side aerosol, and the mixture aerosol. It is thus possible to further improve the quality of experience using the inhaler device 100.

(4) Flow of Processes

FIG. 11 is a flow chart illustrating one example of the flow of processes executed by the inhaler device 100 according to the present embodiment.
As illustrated in FIG. 11, the inhaler device 100 determines whether the first airflow path 180A is open (step S102).
When it is determined that the first airflow path 180A is open (S102: YES), the inhaler device 100 determines whether the stick substrate 150 is received (step S104). When it is determined that the stick substrate 150 is received (S104: YES), the inhaler device 100 permits electric power supply to the stick-side heater 40A and prohibits electric power supply to the cartridge-side heater 40B (step S106). When it is determined that the stick substrate 150 is not received (S104: NO), the inhaler device 100 prohibits electric power supply to the stick-side heater 40A and the cartridge-side heater 40B (step S108).
When it is determined that the first airflow path 180A is not open (S102: NO), the inhaler device 100 determines whether the second airflow path 180B is open (step S110).
When it is determined that the second airflow path 180B is open (S110: YES), the inhaler device 100 determines whether the stick substrate 150 is received (step S112). When it is determined that the stick substrate 150 is received (S112: YES), the inhaler device 100 permits electric power supply to the stick-side heater 40A and the cartridge-side heater 40B (step S 114).
When it is determined that the stick substrate 150 is not received (step S112: NO), the inhaler device 100 determines whether the mouthpiece 168 is attached (step S116). When it is determined that the mouthpiece 168 is attached (S116: YES), the inhaler device 100 prohibits electric power supply to the stick-side heater 40A and permits electric power supply to the cartridge-side heater 40B (step S118). When it is determined that the mouthpiece 168 is not attached (S116: NO), the inhaler device 100 prohibits electric power supply to the stick-side heater 40A and the cartridge-side heater 40B (step S120). When it is determined that the second airflow path 180B is not open (S110: NO), the inhaler device 100 similarly prohibits electric power supply to the stick-side heater 40A and the cartridge-side heater 40B (step S120).
