As an example, the sensor unit 112 is composed of a pressure sensor such as a microphone capacitor, a flow rate sensor, or a temperature sensor. Then, when the sensor unit 112 detects a numerical value associated with the suction by the user, the sensor unit 112 outputs information indicating that the suction by the user has been performed to the control unit 116. As another example, the sensor unit 112 is configured by an input device such as a button or a switch that receives input of information from the user. In particular, the sensor unit 112 may include a button instructing the start / stop of aerosol production. Then, the sensor unit 112 outputs the information input by the user to the control unit 116. As another example, the sensor unit 112 is configured by a temperature sensor that detects the temperature of the heating unit 40A. Such a temperature sensor detects, for example, the temperature of the heating unit 40A based on the electric resistance value of the conductive track of the heating unit 40A. The sensor unit 112 may detect the temperature of the stick-type base material 150 received in the chamber 50 based on the temperature of the heating unit 40A.

The notification unit 113 notifies the user of the information. As an example, the notification unit 113 is configured by a light emitting device such as an LED (Light Emitting Diode). In that case, the notification unit 113 emits light with different light emission patterns when the state of the power supply unit 111 requires charging, when the power supply unit 111 is charging, or when an abnormality occurs in the suction device 100. ..

The notification unit 113 may be configured with or instead of a light emitting device, including a display device for displaying an image, a sound output device for outputting sound, a vibrating device, and the like. In addition, the notification unit 113 may notify the information indicating that the suction by the user has become possible. Information indicating that suction by the user has become possible is notified when the temperature of the stick-type base material 150 heated by the heating unit 40A reaches a predetermined temperature.

The storage unit 114 stores various information for the operation of the suction device 100. The storage unit 114 is composed of a non-volatile storage medium such as a 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 the control contents of various components by the control unit 116. Another example of the information stored in the storage unit 114 is information related to suction by the user, such as the number of suctions, the suction time, and the cumulative suction time.

The communication unit 115 is a communication interface for transmitting and receiving information between the suction device 100 and another device. The communication unit 115 performs 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 transmits the information on the suction by the user to the smartphone in order to display the information on the suction by the user on the smartphone. As another example, the communication unit 115 receives 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 unit and a control device, and controls the overall operation in the suction device 100 according to various programs. The control unit 116 is realized by, for example, an electronic circuit such as a CPU (Central Processing Unit) and a microprocessor. In addition, the control unit 116 may include a ROM (Read Only Memory) for storing a program to be used, calculation parameters, and the like, and a RAM (Random Access Memory) for temporarily storing parameters and the like that change as appropriate.

The liquid storage unit 123 stores the aerosol source. The aerosol source is atomized by heating to produce an aerosol. Aerosol sources are, for example, polyhydric alcohols such as glycerin and propylene glycol, and liquids such as water. The aerosol source may further comprise a tobacco source or an extract derived from the tobacco source that releases the flavor component upon heating. Aerosol sources may further contain nicotine. If the aspirator 100 is a medical inhaler such as a nebulizer, the aerosol source may include a drug for the patient to inhale.

The liquid guiding unit 122 guides and holds the aerosol source, which is the liquid stored in the liquid storage unit 123, from the liquid storage unit 123. The liquid guiding portion 122 is a wick formed by twisting a fiber material such as glass fiber or a porous material such as a porous ceramic. The liquid guiding unit 122 communicates with the liquid storage unit 123. Therefore, the aerosol source stored in the liquid storage unit 123 spreads throughout the liquid induction unit 122 due to the capillary effect.

The heating unit 40B heats the aerosol source to atomize the aerosol source and generate an aerosol. The heating unit 40B is formed of any material such as metal or polyimide in any shape such as coil shape, film shape or blade shape. The heating unit 40B is arranged close to the liquid induction unit 122. In the example shown in FIG. 1, the heating unit 40B is composed of a metal coil and is wound around the liquid induction unit 122. Therefore, when the heating unit 40B generates heat, the aerosol source held in the liquid induction unit 122 is heated and atomized, and an aerosol is generated. The heating unit 40B generates heat when power is supplied from the power supply unit 111. As an example, a power may be supplied to generate an aerosol during a period in which the sensor unit 112 detects that suction has been performed by the user. As another example, when the sensor unit 112 detects that a predetermined user input (for example, pressing a button instructing start / stop of aerosol generation) has been performed, power is supplied and the aerosol is generated. good. After that, when the sensor unit 112 detects that a predetermined user input (for example, pressing the button for instructing the start / stop of aerosol generation again) has been performed, the power supply may be stopped.

The chamber 50 receives the stick-type base material 150 inserted through the first opening 52. For example, the chamber 50 is a tubular body having a first opening 52 and a bottom portion 54 as a bottom surface, and defines a columnar internal space 80. The bottom 54 of the chamber 50 is provided with a second opening 56. The chamber 50 also has the function of defining an air flow path through the stick-type substrate 150. The air inlet into the flow path is the second opening 56. On the other hand, the outlet of air from such a flow path is the first opening 52.

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

The base material portion 151 contains an aerosol source. The aerosol source is atomized by heating to produce an aerosol. The aerosol source may be derived from tobacco, for example, a processed product obtained by molding chopped tobacco or a tobacco raw material into granules, sheets, or powder. Also, the aerosol source may include non-tobacco-derived ones made from plants other than tobacco (eg, mint, herbs, etc.). As an example, the aerosol source may contain a fragrance component such as menthol. If the aspirator 100 is a medical inhaler, the aerosol source may include a drug for the patient to inhale. The aerosol source is not limited to a solid, and may be, for example, a polyhydric alcohol such as glycerin and propylene glycol, and a liquid such as water. At least a part of the base material portion 151 is housed in the internal space 80 of the chamber 50 in a state where the stick-type base material 150 is received in the chamber 50.

The mouthpiece 152 is a member that can be held by the user during suction. At least a portion of the mouthpiece 152 projects from the first opening 52 with the stick-type substrate 150 received in the chamber 50. Then, when the user holds and sucks the mouthpiece 152 protruding from the first opening 52, air flows into the internal space 80 of the chamber 50 from the second opening 56. The inflowing air passes through the internal space 80 of the chamber 50, more specifically through the base material portion 151, and reaches the user's mouth together with the aerosol generated from the base material portion 151.

The heating unit 40A heats the aerosol source to atomize the aerosol source and generate an aerosol. The heating unit 40A is made of any material such as metal or polyimide. For example, the heating unit 40A is formed in a film shape and is arranged so as to cover the outer periphery of the chamber 50. Then, when the heating unit 40A generates heat, the aerosol source contained in the stick-type base material 150 is heated from the outer periphery of the stick-type base material 150 and atomized to generate an aerosol. The heating unit 40A generates heat when power is supplied from the power supply unit 111. As an example, when a predetermined user input is detected by the sensor unit 112, power may be supplied and an aerosol may be generated. When the temperature of the stick-type base material 150 heated by the heating unit 40A reaches a predetermined temperature, suction by the user becomes possible. After that, when the sensor unit 112 detects that a predetermined user input has been performed, the power supply may be stopped. As another example, a power may be supplied to generate an aerosol during a period in which the sensor unit 112 detects that suction has been performed by the user.

The heat insulating portion 70 prevents heat transfer from the heating portion 40A to other components of the suction device 100. The heat insulating portion 70 is arranged so as to cover at least the outer periphery of the heating portion 40A. For example, the heat insulating portion 70 is composed of a vacuum heat insulating material, an airgel heat insulating material, and the like. The vacuum heat insulating material is, for example, a heat insulating material in which glass wool, silica (silicon powder), or the like is wrapped in a resin film to create a high vacuum state, so that heat conduction by gas is made as close to zero as possible. be.

The air flow path 180 is an air flow path introduced into the internal space 80 of the chamber 50. The air flow path 180 may have a tubular structure having an air inflow hole 181 which is an inlet of air into the air flow path 180 and a bottom portion 54 of the chamber 50 at both ends. The second opening 56 provided in the bottom 54 of the chamber 50 is an outlet for air from the air flow path 180. That is, the internal space 80 of the chamber 50 and the air flow path 180 are air-communicated through the second opening 56 of the chamber 50. With suction by the user, air flows into the air flow path 180 from the air inflow hole 181 and flows out from the second opening 56 to the internal space 80 of the chamber 50. A liquid guiding unit 122 and a heating unit 40B are arranged in the middle of the air flow path 180. The aerosol generated by the heating unit 40B is mixed with the air flowing in from the air inflow hole 181. Then, with suction by the user, the mixed fluid of aerosol and air is transported to the interior space 80 of the chamber 50 via the second opening 56, as shown in the air flow 190. Then, the mixed fluid of the aerosol and the air transported to the internal space 80 of the chamber 50 reaches the user's mouth together with the aerosol generated by the heating unit 40A.

-Modification Example The configuration example of the suction device 100 has been described above. Of course, the configuration of the suction device 100 is not limited to the above, and various configurations exemplified below may be adopted.

As an example, the aerosol may be generated by vibration or induction heating instead of heating by the heating unit 40B.

When the aerosol is generated by vibration, the suction device 100 includes a vibration unit instead of the heating unit 40B. For example, the vibrating portion is composed of a plate-shaped member containing piezoelectric ceramics that functions as an ultrasonic vibrator. Then, when the vibrating portion vibrates, the aerosol source guided to the surface of the vibrating portion by the liquid guiding portion 122 is atomized by the ultrasonic waves generated by the vibration by the vibrating portion, and the aerosol is generated.

When the aerosol is generated by induction heating, the suction device 100 includes a susceptor and an electromagnetic induction source instead of the heating unit 40B. The susceptor generates heat due to electromagnetic induction. The susceptor is made of a conductive material such as metal. The susceptor is arranged in close proximity to the liquid guiding portion 122. For example, the susceptor is composed of a metal lead wire and is wound around the liquid guiding portion 122. The electromagnetic induction source heats the susceptor by electromagnetic induction. The electromagnetic induction source is composed of, for example, a coiled conductor. The electromagnetic induction source generates a magnetic field when an alternating current is supplied from the power supply unit 111. The electromagnetic induction source is arranged at a position where the susceptor is superposed on the generated magnetic field. Therefore, when a magnetic field is generated, an eddy current is generated in the susceptor and Joule heat is generated. Then, the aerosol source held in the liquid induction unit 122 is heated and atomized by the Joule heat to generate an aerosol.

As another example, the aerosol may be generated by induction heating instead of heating by the heating unit 40A.

In that case, the stick-type base material 150 further contains a susceptor. The susceptor generates heat due to electromagnetic induction. The susceptor is made of a conductive material such as metal. As an example, the susceptor is a piece of metal. The susceptor is placed in close proximity to the aerosol source. For example, the susceptor is included in the base material portion 151 of the stick-type base material 150.

Further, the suction device 100 includes an electromagnetic induction source instead of the heating unit 40A. The electromagnetic induction source is composed of, for example, a coiled lead wire, and is arranged so as to wrap around the outer periphery of the chamber 50. The electromagnetic induction source generates a magnetic field when an alternating current is supplied from the power supply unit 111. The electromagnetic induction source is arranged at a position where the internal space 80 of the chamber 50 is superimposed on the generated magnetic field. Therefore, when a magnetic field is generated while the stick-type base material 150 is received in the chamber 50, an eddy current is generated in the susceptor and Joule heat is generated. Then, the aerosol source contained in the stick-type base material 150 is heated and atomized by the Joule heat to generate an aerosol.

As another example, the heating unit 40A may be configured in a blade shape and may be arranged so as to project from the bottom portion 54 of the chamber 50 to the internal space 80. In that case, the blade-shaped heating portion 40A is inserted into the base material portion 151 of the stick-type base material 150, and the base material portion 151 of the stick-type base material 150 is heated from the inside. As another example, the heating unit 40A may be arranged so as to cover the bottom portion 54 of the chamber 50. Further, the heating unit 40A may be configured as a combination of two or more of the heating unit covering the outer periphery of the chamber 50, the blade-shaped heating unit, and the heating unit covering the bottom portion 54 of the chamber 50.

As another example, the chamber 50 may include an opening / closing mechanism such as a hinge that opens / closes a part of the outer shell forming the internal space 80. Then, the chamber 50 may sandwich the stick-type base material 150 inserted in the internal space 80 by opening and closing the outer shell. In that case, the heating unit 40A may be provided at the sandwiched portion in the chamber 50 and may be heated while pressing the stick-type base material 150.

Also, the means for producing aerosols is not limited to heating. For example, the means for producing the aerosol may be oscillating atomization or induction heating.

-Supplement The heating unit 40A is an example of a first generation unit that produces an aerosol using the first substrate. The stick-type substrate 150 is an example of a first substrate containing an aerosol source. Hereinafter, the heating unit 40A is also referred to as a stick-side heating unit 40A. The heating unit 40B is an example of a second generation unit that produces an aerosol using the second substrate. The cartridge 120 is an example of a second substrate containing an aerosol source that is a liquid. Hereinafter, the heating unit 40B is also referred to as a cartridge side heating unit 40B.

The aerosol generated by the stick-side heating unit 40A is also referred to as a stick-side aerosol. On the other hand, the aerosol generated by the cartridge-side heating unit 40B is also referred to as a cartridge-side aerosol. When it is not necessary to distinguish between the stick-side aerosol and the cartridge-side aerosol, these are also collectively referred to simply as an aerosol.

<< 2. Technical issues >>
As described above with reference to FIG. 1, the suction device 100 uses two base materials, a cartridge 120 and a stick-type base material 150, in combination. Therefore, the user can suck and taste the mixed aerosol in which the stick-side aerosol and the cartridge-side aerosol are mixed. As described above, the suction device 100 that produces a mixed aerosol by using two types of substrates in combination is also referred to as a hybrid type.

Here, it is considered that the user may want to taste only the stick-side aerosol, the cartridge-side aerosol only, or the mixed aerosol. Therefore, in the present embodiment, a mechanism capable of switching the operation of the suction device 100 according to these requests is provided. That is, the suction device 100 according to the present embodiment can selectively generate each of the stick-side aerosol and the cartridge-side aerosol.

<< 3. Technical features >>
(1) Detailed Configuration Example of the Suction Device 100 Hereinafter, a detailed configuration example of the suction device 100 will be described with reference to FIGS. 2 to 7.

Then, depending on the position of the slider 184, the first opening 52, the first air inflow hole 181A, and the second air inflow hole 181B are opened and closed. Here, closing the hole such as the first opening 52 means that the hole is covered by the slider 184 and it becomes difficult for air to flow in and out through the hole. On the other hand, opening a hole such as the first opening 52 means that the hole is exposed and air can flow in and out through the hole. With such a configuration, it becomes possible to easily control the inflow and outflow of air into and out of the suction device 100.

FIG. 3 is a top view of the suction device 100 in a state where the first opening 52 is closed by the slider 184. On the other hand, the first air inflow hole 181A and the second air inflow hole 181B are open.

On the other hand, the first opening 52 and the first air inflow hole 181A are open. FIG. 5 is a top view of the suction device 100 in a state where the first air inflow hole 181A is closed by the slider 184. On the other hand, the first opening 52 and the second air inflow hole 181B are open. FIG. 6 is a diagram schematically showing an example of the internal configuration of the suction device 100 that receives the stick-type base material 150 in the state shown in FIG. FIG. 7 is a diagram schematically showing an example of the internal configuration of the suction device 100 that receives the stick-type base material 150 in the state shown in FIG.

As shown in FIGS. 3 to 5, the slider 184 rotates on the top surface 102 of the suction device 100 with the center of the top surface 102 of the suction device 100 as the rotation axis. The user can open and close the first opening 52, the first air inflow hole 181A, and the second air inflow hole 181B by sliding the slider 184.

As shown in FIGS. 6 and 7, the chamber 50 receives the stick-type base material 150. In this state, the stick-side heating unit 40A heats the stick-type base material 150 to generate a stick-side aerosol. The second opening 56 is arranged at a position where the chamber 50 communicates with the end face (that is, the end face of the base material portion 151) in the chamber 50 of the stick type base material 150 in a state where the chamber 50 receives the stick type base material 150. .. Therefore, when the user holds the stick-type base material 150 and sucks it, the air flowing into the chamber 50 from the second opening 56 flows from the end of the stick-type base material 150 into the chamber 50 to the inside of the stick-type base material 150. Inflow to. Then, the air that has flowed into the stick-type base material 150 is mixed with the stick-side aerosol in the process of being transported via the inside of the stick-type base material 150, and the end face outside the chamber 50 of the stick-type base material 150 ( That is, it reaches the user's mouth from the end face of the mouthpiece 152).

As shown in FIG. 6, the suction device 100 is formed with a first air flow path 180A for air communication between the first air inflow hole 181A and the second opening 56 as one of the air flow paths 180. .. The air flowing in from the first air inflow hole 181A is transported by the first air flow 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-type base material 150 and sucks the air, air is transported along the air flow 190A and reaches the user's mouth together with the stick-side aerosol.

As shown in FIG. 7, the suction device 100 is formed with a second air flow path 180B for air communication between the second air inflow hole 181B and the second opening 56 as one of the air flow paths 180. .. A cartridge-side heating unit 40B is arranged in the middle of the second air flow path 180B. When the cartridge-side heating unit 40B heats the aerosol source introduced from the liquid storage unit 123 to the liquid induction unit 122, the cartridge-side aerosol is generated. The air flowing in from the second air inflow hole 181B is mixed with the aerosol on the cartridge side while being transported by the second air flow path 180B, flows into the internal space 80 of the chamber 50 through the second opening 56, and further. Mix with stick side aerosol. Therefore, when the user holds and sucks the stick-type base material 150, air is transported along the air flow 190B and reaches the user's mouth together with the mixed aerosol.

Here, as shown in FIGS. 6 and 7, a part of the first air flow path 180A on the second opening 56 side and a part of the second air flow path 180B on the second opening 56 side. Are duplicated. However, the cartridge-side heating unit 40B is arranged at a position that does not overlap with the first air flow path 180A in the second air flow path 180B. Along with this, the liquid guiding portion 122 is also arranged at a position that does not overlap with the first air flow path 180A in the second air flow path 180B. In other words, the cartridge-side heating unit 40B and the liquid induction unit 122 are not arranged in the first air flow path 180A. With such a configuration, the flavor of the aerosol source induced in the liquid guiding portion 122 is prevented from being attached to the air transported along the air flow 190A. Therefore, when the user sucks in a state where the first air flow path 180A is opened and the second air flow path 180B is closed, the flavor is not deteriorated by the cartridge-side aerosol, and the flavor of the pure stick-side aerosol is not deteriorated. Can be tasted.

The slider 184 is an example of an opening / closing portion that opens / closes each of the first air flow path 180A and the second air flow path 180B. As shown in FIG. 6, the slider 184 can open the first air flow path 180A and close the second air flow path 180B by closing the second air inflow hole 181B. As shown in FIG. 7, the slider 184 can open the second air flow path 180B and close the first air flow path 180A by closing the first air inflow hole 181A.

The sensor unit 112 further includes a hall sensor that detects the position of the slider 184. The Hall sensor is a non-contact magnetic sensor that uses the Hall effect to change the magnetic field into an electrical signal. As an example, a magnet is built in the slider 184, and a Hall element is provided on the top surface 102 of the suction device 100. The Hall sensor can detect the position of the slider 184 based on the output from the Hall element by storing in advance the correspondence between the position of the slider 184 and the electric signal output from the Hall element. The control unit 116 determines the open / closed state of the first air flow path 180A and the second air flow path 180B based on the position of the slider 184 detected by the Hall sensor. For example, when the position of the slider 184 is the position shown in FIG. 4, the control unit 116 determines that the first air flow path 180A is open and the second air flow path 180B is closed. .. Further, when the position of the slider 184 is the position shown in FIG. 5, the control unit 116 determines that the first air flow path 180A is closed and the second air flow path 180B is open. ..

As shown in FIGS. 6 and 7, the second air flow path 180B is shorter than the first air flow path 180A. According to such a configuration, it is possible to suppress the temperature drop until the cartridge-side aerosol generated by the cartridge-side heating unit 40B is transported to the chamber 50. Therefore, it is possible to prevent the cartridge-side aerosol from condensing before being transported to the chamber 50. Further, since the aerosol on the cartridge side is transported to the chamber 50 while keeping the temperature high, it is possible to suppress the temperature drop of the stick-type base material 150.

As shown in FIGS. 6 and 7, the liquid reservoir 186 is provided at a position where air communicates with the first air flow path 180A and the second air flow path 180B. The liquid reservoir 186 can store the liquid generated by the condensation of the aerosol in the suction device 100. 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-type base material 150. Therefore, the liquid generated by the condensation of the aerosol in the chamber 50 can be made to flow down from the second opening 56 into the liquid reservoir 186. Further, the liquid generated by condensing the aerosol on the cartridge side before reaching the chamber 50 can also flow down to the liquid reservoir 186 through the second air flow path 180B.

The discharge mechanism 160 is a mechanism for discharging the liquid accumulated in the liquid reservoir 186 to the outside of the suction device 100. The discharge mechanism 160 includes a discharge hole 162 provided in the suction device 100, an on-off valve 164 for opening and closing the discharge hole 162, and a discharge path 166 communicating the discharge hole 162 and the liquid reservoir 186. With the discharge hole 162 opened by the on-off valve 164, the suction device 100 is tilted so that the discharge hole 162 is at the bottom, so that the aerosol as a liquid collected in the liquid reservoir 186 is passed through the discharge hole 166 and is discharged. It can be discharged from 162 to the outside of the suction device 100. With such a configuration, it is possible to prevent the condensed liquid from staying in the air flow path 180, so that the heating efficiency can be improved and the risk of failure can be reduced.

(2) Switching between the stick heating type and the hybrid type The control unit 116 has the stick side heating unit 40A and the cartridge side heating unit 40B based on the open / closed state of the first air flow path 180A and the second air flow path 180B. Controls the behavior of. With such a configuration, as will be described in detail below, the suction device 100 can selectively generate each of the stick-side aerosol and the cartridge-side aerosol.

Specifically, the control unit 116 controls whether or not to supply power to each of the stick-side heating unit 40A and the cartridge-side heating unit 40B based on the open / closed state of the first air flow path 180A and the second air flow path 180B. .. The control unit 116 executes power supply to the heating unit 40 to which power supply is permitted when a predetermined condition is satisfied. On the other hand, the control unit 116 does not supply power to the heating unit 40 for which power supply is prohibited. With such a configuration, heating by each of the stick-side heating unit 40A and the cartridge-side heating unit 40B can be selectively executed.

When the power supply to the stick side heating unit 40A is permitted, the control unit 116 controls to start continuous power supply to the stick side heating unit 40A from the timing when a predetermined input is detected. An example of a predetermined input is a user operation such as pressing a button to instruct the start of heating of the stick-type base material 150. On the other hand, when the power supply to the stick-side heating unit 40A is prohibited, the control unit 116 controls so that the power supply to the stick-side heating unit 40A is not started even if a predetermined input is detected. The stick-type base material 150 is continuously heated by the stick-side heating unit 40A to raise the temperature, so that a sufficient aerosol can be continuously generated. Therefore, according to such a configuration, it is possible to control whether or not the stick-side aerosol is generated depending on whether or not the power supply to the stick-side heating unit 40A is permitted or rejected.

When the power supply to the cartridge side heating unit 40B is permitted, the control unit 116 controls to supply power to the cartridge side heating unit 40B at the timing when it is detected that the suction has been performed by the user. On the other hand, the control unit 116 controls not to supply power to the cartridge side heating unit 40B even when it is detected that the suction has been performed by the user when the power supply to the cartridge side heating unit 40B is prohibited. The aerosol source introduced from the liquid storage unit 123 to the liquid induction unit 122 is instantaneously heated by the cartridge-side heating unit 40B to sufficiently raise the temperature, and the cartridge-side aerosol can be generated. Therefore, according to such a configuration, it is possible to control whether or not the cartridge-side aerosol is generated depending on whether or not the power supply to the cartridge-side heating unit 40B is permitted or rejected.

As shown in FIG. 6, the control unit 116 permits power supply to the stick-side heating unit 40A when the first air flow path 180A is open and the second air flow path 180B is closed, and the cartridge Power supply to the side heating unit 40B is prohibited. With such a configuration, the cartridge-side aerosol is not generated, so that the user can aspirate only the stick-side aerosol with the air transported along the airflow 190A. That is, the suction device 100 can operate as a stick-heated suction device 100 that produces only the stick-side aerosol.

As shown in FIG. 7, the control unit 116 has both the stick-side heating unit 40A and the cartridge-side heating unit 40B when the second air flow path 180B is open and the first air flow path 180A is closed. Allow power supply to. With such a configuration, both the cartridge-side aerosol and the stick-side aerosol are produced so that the user can aspirate the mixed aerosol with the air transported along the air stream 190B. That is, the suction device 100 can operate as a hybrid type suction device 100 that produces a mixed aerosol.

It is also assumed that at least a part of both the first air flow path 180A and the second air flow path 180B is opened depending on the position of the slider 184. In such a case, the control unit 116 prohibits power supply to both the stick-side heating unit 40A and the cartridge-side heating unit 40B. With such a configuration, it is possible to prevent malfunction.

Further, the control unit 116 permits power supply to the stick-side heating unit 40A when the stick-type base material 150 is accepted in the chamber 50, and prohibits power supply to the stick-side heating unit 40A otherwise. With such a configuration, so-called empty heating can be prevented. The sensor unit 112 further includes a sensor for detecting whether or not the stick-type base material 150 is received in the chamber 50.

As described above, the suction device 100 according to the present embodiment can be switched to either the stick heating type or the hybrid type depending on the open / closed state of the air flow path 180. Therefore, the user can easily taste the stick-side aerosol or the mixed aerosol. In this way, the quality of the experience with the suction device 100 can be improved.

(3) Switching to the cartridge type The suction device 100 may operate as a cartridge heating type suction device 100 that produces only the aerosol on the cartridge side. This point will be described in detail with reference to FIGS. 8 to 10.

FIG. 8 is a diagram schematically showing an example of the internal configuration of the suction device 100 that does not accept the stick-type base material 150 in the state shown in FIG. As in the example shown in FIG. 8, when the second air flow path 180B is open and the stick type base material 150 is not received in the chamber 50, the control unit 116 transfers to the stick side heating unit 40A. Power supply is prohibited and power supply to the cartridge side heating unit 40B is permitted. Then, the control unit 116 controls to supply power to the cartridge side heating unit 40B at the timing when it is detected that the suction by the user has been performed. This produces an aerosol on the cartridge side. The user can taste only the cartridge-side aerosol by, for example, sucking the first opening 52 with a mouth. That is, the suction device 100 can operate as a cartridge heating type.

A mouthpiece may be attached to the suction device 100 as an option when operating as a cartridge heating type. FIG. 9 is a diagram schematically showing an example of the internal configuration of the suction device 100 to which the mouthpiece is attached in the state shown in FIG. In the example shown in FIG. 9, the slider 184 closes the first air inflow hole 181A, and the second air flow path 180B is open. A mouthpiece 168 is attached near the first opening 52.

In the control unit 116, when the second air flow path 180B is open, the stick type base material 150 is not received in the chamber 50, and the mouthpiece 168 is attached, the control unit 116 goes to the stick side heating unit 40A. The power supply to the cartridge side heating unit 40B is permitted. Then, the control unit 116 controls to supply power to the cartridge side heating unit 40B at the timing when it is detected that the suction by the user has been performed. This produces an aerosol on the cartridge side. The user can taste only the aerosol on the cartridge side by holding and sucking the mouthpiece 168. According to such a configuration, the user can comfortably suck the aerosol as compared with the case where the first opening 52 is sucked with the mouth.

In the control unit 116, when the second air flow path 180B is open, the stick-type base material 150 is not accepted in the chamber 50, and the mouthpiece 168 is not attached, the stick-side heating unit Power supply to 40A and the cartridge side heating unit 40B may be prohibited. According to such a configuration, the suction device 100 can operate as a cartridge heating type only when the mouthpiece 168 is attached.

FIG. 10 is a diagram showing an example of the configuration of the chamber 50. As shown in FIG. 10, the chamber 50 has a holding portion 60 and a non-holding portion 62. The holding portion 60 holds the stick-type base material 150 inserted through the first opening 52. As an example, the holding portion 60 is configured so that at least a part of the inner diameter is shorter than the outer diameter of the stick-type base material 150, and holds the stick-type base material 150 by pressing it from the outer circumference. The non-holding portion 62 is arranged closer to the first opening 52 than the holding portion 60. As an example, the non-holding portion 62 is configured such that the inner diameter is longer than the outer diameter of the stick-type base material 150, and is in contact with the stick-type base material 150 even when the stick-type base material 150 is held by the holding portion 60. do not do. As shown in FIG. 10, the mouthpiece 168 inserted through the first opening 52 is attached to the inside of the non-holding portion 62. Specifically, the mouthpiece 168 is attached so that the outer surface of the lower end portion of the mouthpiece 168 is in close contact with the inner surface of the non-holding portion 62. The inner diameter of the non-holding portion 62 is larger than the inner diameter of the holding portion 60. With this configuration, a step 64 due to the difference in inner diameter is formed at the boundary portion between the holding portion 60 and the non-holding portion 62, so that the mouthpiece 168 can be appropriately positioned by the step 64.

A sensor 170 for detecting whether or not the mouthpiece 168 is attached is arranged in the non-holding portion 62. As an example, the sensor 170 may be a proximity sensor that detects a nearby object. With such a configuration, it becomes possible to automatically switch to the cartridge heating type. The sensor 170 may also serve as a sensor for detecting whether or not the stick-type base material 150 is received in the chamber 50. As an example, the sensor 170 configured as a proximity sensor may detect the attachment of the mouthpiece 168 or the acceptance of the stick-type substrate 150, depending on the distance to a nearby object.

As shown in FIG. 10, the stick-side heating portion 40A is arranged on the outer surface of the holding portion 60. For example, the stick-side heating portion 40A is arranged over the entire outer circumference of the holding portion 60 so as to surround the outer circumference of the holding portion 60. With such a configuration, the stick-type base material 150 held by the holding portion 60 can be efficiently heated. Further, by not arranging the stick-side heating portion 40A in the non-holding portion 62, when the mouthpiece 168 is attached to the non-holding portion 62, the mouthpiece 168 deteriorates due to the residual heat of the stick-side heating portion 40A. Can be prevented.

As described above, the suction device 100 according to the present embodiment can be operated by switching to either a cartridge heating type, a stick heating type, or a hybrid type. Therefore, the user can easily taste any one of the cartridge-side aerosol, the stick-side aerosol, and the mixed aerosol. In this way, the quality of the experience using the suction device 100 can be further improved.

(4) Process Flow FIG. 11 is a flowchart showing an example of a process flow executed by the suction device 100 according to the present embodiment.

Step S106). On the other hand, when it is determined that the stick-type base material 150 is not accepted (S104: NO), the suction device 100 prohibits power supply to the stick-side heating unit 40A and the cartridge-side heating unit 40B (step S108).

When it is determined that the second air flow path 180B is open (S110: YES), the suction device 100 determines whether or not the stick-type base material 150 is accepted (step S112). When it is determined that the stick-type base material 150 is accepted (S112: YES), the suction device 100 permits power supply to the stick-side heating unit 40A and the cartridge-side heating unit 40B (step S114).

On the other hand, when it is determined that the stick-type base material 150 is not accepted (step S112: NO), the suction device 100 determines whether or not the mouthpiece 168 is attached (step S116). When it is determined that the mouthpiece 168 is attached (S116: YES), the suction device 100 prohibits power supply to the stick side heating unit 40A and permits power supply to the cartridge side heating unit 40B (step S118). ). On the other hand, when it is determined that the mouthpiece 168 is not attached (S116: NO), the suction device 100 prohibits power supply to the stick side heating unit 40A and the cartridge side heating unit 40B (step S120). Similarly, when it is determined that the second air flow path 180B is not open (S110: NO), the suction device 100 prohibits power supply to the stick side heating unit 40A and the cartridge side heating unit 40B (step). S120).
