There is. Inside the power supply unit case 11, an LDO regulator 65 (LDO: Low Drop Out), a DC / DC converter 66, a first temperature detection element 67 including a voltage sensor 671 and a current sensor 672, and a voltage sensor A second temperature detection element 68, including a 681 and a current sensor 682, is housed (see also FIGS. 6 and 7).

The power source 61 is a chargeable / dischargeable power storage device such as a secondary battery or an electric double layer capacitor, and is preferably a lithium ion secondary battery. The electrolyte of the power supply 61 can be composed of one or a combination of a gel-like electrolyte, an electrolyte, a solid electrolyte, and an ionic liquid.

The intake sensor 62 is a pressure sensor that detects a puff (suction) operation, and is provided, for example, in the vicinity of the operation unit 15. The intake sensor 62 is configured to output a value of a change in pressure (internal pressure) inside the power supply unit 10 caused by suction by the user through the suction port 58 of the capsule 50, which will be described later. For example, the intake sensor 62 has an output value (for example, a voltage value) according to the internal pressure that changes according to the flow rate of air sucked from the air intake port toward the suction port 58 of the capsule 50 (that is, the suction operation of the user). Or the current value) is output. The intake sensor 62 may output an analog value or may output a digital value converted from the analog value.

The intake sensor 62 may include a temperature sensor that detects the temperature (outside air temperature) of the environment in which the power supply unit 10 is placed in order to compensate for the pressure to be detected. Further, the intake sensor 62 may be composed of a condenser microphone, a flow rate sensor, or the like instead of the pressure sensor.

The MCU 63 is an electronic component (controller) that controls various types of the aerosol aspirator 1.

It further includes 63a (see FIG. 6). The processor in the present specification is specifically an electric circuit in which circuit elements such as semiconductor elements are combined.

The MCU 63 determines that an aerosol generation request has been made when the output value of the intake sensor 62 exceeds the threshold value, for example, due to a suction operation performed by the user. After that, the MCU 63 determines that, for example, when the suction operation by the user is completed and the output value of the intake sensor 62 is below the above threshold value, the aerosol generation request is completed. In this way, the output value of the intake sensor 62 is used as a signal indicating an aerosol generation request. Therefore, the intake sensor 62 constitutes a sensor that outputs an aerosol generation request. The intake sensor 62 may determine whether or not there is an aerosol generation request instead of the MCU 63, and the MCU 63 may receive a digital value according to the determination result from the intake sensor 62. As a specific example, the intake sensor 62 outputs a high-level signal when it is determined that there is an aerosol generation request, and determines that the aerosol generation request has disappeared (that is, the aerosol generation request has been completed). In some cases, a low level signal may be output. Further, the threshold value determined by the MCU 63 or the intake sensor 62 that the aerosol generation request has been made may be different from the threshold value determined by the MCU 63 or the intake sensor 62 that the aerosol generation request has been completed.

The MCU 63 may detect the aerosol generation request based on the operation of the operation unit 15 instead of the intake sensor 62. For example, when the user performs a predetermined operation on the operation unit 15 to start suctioning the aerosol, the operation unit 15 may be configured to output a signal indicating an aerosol generation request to the MCU 63. In this case, the operation unit 15 constitutes a sensor that outputs an aerosol generation request.

The charging IC 64 is provided in the vicinity of the charging terminal 14. The charging IC 64 controls the electric power input from the charging terminal 14 and charged to the power source 61 to control the charging of the power source 61.

The second load 34 of the capsule holder 30 is electrically connected to the power supply 61 of the power supply unit 10 via the discharge terminal 17 and the connection terminal of the capsule holder 30 by coming into contact with the connection terminal (not shown). NS.

(capsule)
Returning to FIG. 3, the capsule 50 has a substantially cylindrical shape and includes a side wall 51 having both end faces open and extending in a substantially annular shape. The side wall 51 is formed of, for example, a resin such as plastic. The side wall 51 has a substantially annular shape having a diameter slightly smaller than that of the inner peripheral surface 31a of the side wall 31 of the capsule holder 30.

The capsule 50 includes a storage chamber 53 in which the flavor source 52 is housed. The containment chamber 53 may be formed in the internal space of the capsule 50 surrounded by the side wall 51, as shown in FIG. Alternatively, the entire internal space of the capsule 50 excluding the outlet portion 55 described later may be the accommodation chamber 53.

The storage chamber 53 includes an inlet portion 54 provided on one end side of the capsule 50 extending in a substantially cylindrical shape in the cylindrical axial direction, and an outlet portion 55 provided on the other end side of the capsule 50 in the cylindrical axial direction.

The flavor source 52 contains tobacco granules 521 obtained by molding the tobacco raw material into granules. Further, in the present embodiment, the regular type capsule 50 containing the flavor source 52 not containing the menthol 80 and the menthol type capsule 50 containing the flavor source 52 containing the menthol 80 are the manufacturers of the aerosol aspirator 1. Provided to the user by such means. In the menthol type capsule 50, for example, the menthol 80 is adsorbed on the tobacco granules 521 constituting the flavor source 52.

The flavor source 52 may contain chopped tobacco instead of the tobacco granules 521. Further, the flavor source 52 may contain a plant other than tobacco (for example, mint, Chinese medicine, herbs, etc.) instead of the tobacco granules 521. Further, the flavor source 52 may be added with another fragrance in addition to the menthol 80.

As shown in FIG. 3, when the storage chamber 53 is formed in the internal space of the capsule 50, the inlet portion 54 is located inside the capsule 50 at a position separated from the bottom of the capsule 50 in the cylindrical axial direction of the capsule 50. It may be a partition wall that divides the space in the cylindrical axis direction of the capsule 50. The inlet portion 54 may be a mesh-like partition wall through which the flavor source 52 cannot pass and the aerosol 72 can pass through.

When the entire internal space of the capsule 50 excluding the outlet portion 55 is the accommodation chamber 53, the bottom portion of the capsule 50 also serves as the inlet portion 54.

The outlet portion 55 is a filter member filled in the internal space of the capsule 50 surrounded by the side wall 51 at the end portion on the top side of the side wall 51 in the cylindrical axial direction of the capsule 50. The outlet portion 55 is a filter member through which the flavor source 52 cannot pass and the aerosol 72 can pass through. In the present embodiment, the outlet portion 55 is provided near the top of the capsule 50, but the outlet portion 55 may be provided at a position away from the top of the capsule 50.

The accommodation chamber 53 is located between the first space 531 in which the flavor source 52 exists, the first space 531 and the outlet portion 55, is adjacent to the outlet portion 55, and has a second space 532 in which the flavor source 52 does not exist. Have. In the present embodiment, in the accommodation chamber 53, the first space 531 and the second space 532 are formed adjacent to each other in the cylindrical axial direction of the capsule 50. In the first space 531, one end side of the capsule 50 in the cylindrical axis direction is adjacent to the inlet portion 54, and the other end side of the capsule 50 in the cylindrical axis direction is adjacent to the second space 532. In the second space 532, one end side of the capsule 50 in the cylindrical axis direction is adjacent to the first space 531 and the other end side of the capsule 50 in the cylindrical axis direction is adjacent to the outlet portion 55. The first space 531 and the second space 532 may be partitioned by a mesh-like partition wall 56 through which the flavor source 52 cannot pass and the aerosol 72 can pass. The first space 531 and the second space 532 may be formed without using such a partition wall 56. As a specific example, the flavor source 52 is housed in a part of the storage chamber 53 in a pressed state, and the flavor source 52 is difficult to move in the storage chamber 53, so that the first space 531 and the second space 532 are stored. And may be formed. As another specific example, while allowing the flavor source 52 to move freely in the storage chamber 53, the flavor source 52 moves to the bottom side of the storage chamber 53 by gravity when the user performs a suction operation from the mouthpiece 58. Then, the first space 531 and the second space 532 may be formed.

As shown in FIG. 3, when the accommodation chamber 53 is formed in the internal space of the capsule 50, the capsule 50 is provided with a second capsule 50 between the bottom portion and the inlet portion 54 of the capsule 50 in the cylindrical axial direction of the capsule 50. The aerosol flow path 57 may be formed.

The second aerosol flow path 57 is formed by the internal space of the capsule 50 surrounded by the side wall 51 between the bottom portion and the inlet portion 54 of the capsule 50 in the cylindrical axial direction of the capsule 50. Therefore, in the second aerosol flow path 57, the first end portion 571 of the capsule 50 in the cylindrical axial direction is opened at the bottom of the capsule 50, and the second end portion 572 of the capsule 50 in the cylindrical axial direction is the storage chamber 53. It is connected to the accommodation chamber 53 at the entrance portion 54.

The opening area of the communication hole 33 provided in the bottom wall 32 of the capsule holder 30 is larger than the cross-sectional area of the first aerosol flow path 46 of the cartridge 40, and the cross-sectional area of the second aerosol flow path 57 is the cartridge. It is larger than the cross-sectional area of the first aerosol flow path 46 of 40 and the opening area of the communication hole 33 provided in the bottom wall 32 of the capsule holder 30. Therefore, rather than the cross-sectional area of the first end portion 461 of the first aerosol flow path 46 connected to the heating chamber 43 of the cartridge 40, the second end portion 572 of the second aerosol flow path 57 connected to the storage chamber 53 of the capsule 50. The cross-sectional area in is larger. The aerosol flow path 90 in the present embodiment is composed of a first aerosol flow path 46, a communication hole 33, and a second aerosol flow path 57. The cross-sectional area at the first end 461 of the first aerosol flow path 46 connected to the heating chamber 43 is smaller than the cross-sectional area at the second end 462 of the first aerosol flow path 46 connected to the communication hole 33. The cross-sectional area of the first end portion 461 of the first aerosol flow path 46 connected to the heating chamber 43 is smaller than the cross-sectional area of the communication hole 33. The cross-sectional area of the communication hole 33 is smaller than the cross-sectional area of the second aerosol flow path 57. That is, the aerosol flow path 90 has a second end connected to the accommodating chamber 53 rather than the cross-sectional area of the first end 461 of the first aerosol flow path 46 constituting the first end connected to the heating chamber 43. The cross-sectional area at the second end 572 of the constituent second aerosol flow path 57 is larger. Further, the aerosol flow path 90 is formed so that the cross-sectional area increases from the first end portion to the second end portion.

When the entire internal space of the capsule 50 excluding the outlet portion 55 is the accommodation chamber 53, the bottom portion of the capsule 50 also serves as the inlet portion 54, so that the above-mentioned second aerosol flow path 57 is not formed. That is, the aerosol flow path 90 in the present embodiment is composed of the first aerosol flow path 46 and the communication hole 33. The cross-sectional area at the first end 461 of the first aerosol flow path 46 connected to the heating chamber 43 is smaller than the cross-sectional area at the second end 462 of the first aerosol flow path 46 connected to the communication hole 33. The cross-sectional area of the first end portion 461 of the first aerosol flow path 46 connected to the heating chamber 43 is smaller than the cross-sectional area of the communication hole 33. Also in the present embodiment, the aerosol flow path 90 is connected to the accommodating chamber 53 rather than the cross-sectional area of the first end portion 461 of the first aerosol flow path 46 constituting the first end portion connected to the heating chamber 43. The cross-sectional area of the communication holes 33 forming the two ends is larger. Further, the aerosol flow path 90 is formed so that the cross-sectional area increases from the first end portion to the second end portion.

In the state where the capsule 50 is housed in the capsule holder 30, a space may be formed between the bottom wall 32 of the capsule holder 30 and the bottom of the capsule 50. That is, the aerosol flow path 90 in the present embodiment is composed of the first aerosol flow path 46, the communication hole 33, and the space formed between the bottom wall 32 of the capsule holder 30 and the bottom of the capsule 50. .. The cross-sectional area at the first end 461 of the first aerosol flow path 46 connected to the heating chamber 43 is smaller than the cross-sectional area at the second end 462 of the first aerosol flow path 46 connected to the communication hole 33. The cross-sectional area of the first end portion 461 of the first aerosol flow path 46 connected to the heating chamber 43 is smaller than the cross-sectional area of the communication hole 33. The cross-sectional area of the communication hole 33 is smaller than the cross-sectional area of the space formed between the bottom wall 32 of the capsule holder 30 and the bottom of the capsule 50. In this case as well, the aerosol flow path 90 has a second end connected to the accommodating chamber 53 rather than the cross-sectional area of the first end portion 461 of the first aerosol flow path 46 constituting the first end portion connected to the heating chamber 43. The cross-sectional area in the space formed between the bottom wall 32 of the capsule holder 30 and the bottom of the capsule 50, which constitutes the portion, is larger. Further, the aerosol flow path 90 is formed so that the cross-sectional area increases from the first end portion to the second end portion.

The capsule 50 is housed in the hollow portion of the hollow substantially annular capsule holder 30 so that the cylindrical axial direction of the substantially cylindrical shape is the first direction X which is the longitudinal direction of the aerosol aspirator 1. Further, in the capsule 50, in the first direction X, the capsule holder 30 has an inlet portion 54 on the bottom side (that is, the cartridge 40 side) of the aerosol aspirator 1 and an outlet portion 55 on the top side of the aerosol aspirator 1. It is housed in the hollow part. When the capsule 50 is housed in the hollow portion of the capsule holder 30, the capsule holder is such that the other end of the side wall 51 is exposed in the first direction X from the top end of the capsule holder 30. It is housed in 30 hollow portions. The other end of the side wall 51 is a suction port 58 for the user to perform a suction operation when the aerosol suction device 1 is used. The other end of the side wall 51 may have a step so that the capsule holder 30 is easily exposed in the first direction X from the top end.

As shown in FIG. 5, the capsule 50 is housed in the hollow portion of the hollow substantially annular cartridge cover 20, and is placed in the hollow portion of the annular second load 34 provided in the capsule holder 30. , A part of the containment chamber 53 is accommodated.

Returning to FIG. 3, the storage chamber 53 is heated with the heating region 53A in which the second load 34 of the capsule holder 30 is arranged while being housed in the hollow portion of the cartridge cover 20 in the cylindrical axial direction of the capsule 50. It has a non-heated region 53B located between the region 53A and the outlet portion 55, adjacent to the outlet portion 55, and where the second load 34 of the capsule holder 30 is not arranged.

In the present embodiment, in the cylindrical axial direction of the capsule 50, the heated region 53A overlaps at least a part of the first space 531 and the non-heated region 53B overlaps at least a part of the second space 532. In the present embodiment, the first space 531 and the heated region 53A substantially coincide with each other in the cylindrical axial direction of the capsule 50, and the second space 532 and the non-heated region 53B substantially coincide with each other.

(Configuration when using an aerosol aspirator)
The aerosol aspirator 1 configured in this way is used in a state where the cartridge cover 20, the capsule holder 30, the cartridge 40, and the capsule 50 are attached to the power supply unit 10. In this state, the aerosol flow path 90 is provided in the aerosol suction device 1 by at least the first aerosol flow path 46 provided in the cartridge 40 and the communication hole 33 provided in the bottom wall 32 of the capsule holder 30. It is formed. When the accommodation chamber 53 is formed in the internal space of the capsule 50 as shown in FIG. 3, the second aerosol flow path 57 provided in the capsule 50 also forms a part of the aerosol flow path 90. When the capsule 50 is housed in the capsule holder 30, if a space is formed between the bottom wall of the capsule holder 30 and the bottom of the capsule 50, it is formed between the bottom wall of the capsule holder 30 and the bottom of the capsule 50. The space to be created also forms a part of the aerosol flow path 90. The aerosol flow path 90 connects the heating chamber 43 of the cartridge 40 and the storage chamber 53 of the capsule 50, and transports the aerosol 72 generated in the heating chamber 43 from the heating chamber 43 to the storage chamber 53.

When the user performs a suction operation from the suction port 58 during use of the aerosol suction device 1, the air flowing in from the air intake port (not shown) provided in the power supply unit case 11 is indicated by the arrow B in FIG. As shown by, the air is taken into the heating chamber 43 of the cartridge 40 from the air supply unit 13 provided on the top surface 11a of the power supply unit case 11. Further, the first load 45 generates heat, the aerosol source 71 held in the wick 44 is heated, and the aerosol source 71 heated by the first load 45 is vaporized and / or atomized in the heating chamber 43. Then, the aerosol source 71 vaporized and / or atomized by the first load 45 is aerosolized using the air taken into the heating chamber 43 from the air supply unit 13 of the power supply unit case 11 as a dispersion medium. The aerosol source 71 vaporized and / or atomized in the heating chamber 43 and the air taken into the heating chamber 43 from the air supply unit 13 of the power supply unit case 11 are connected to the first aerosol flow path 46 communicating with the heating chamber 43. From the first end portion 461 to the second end portion 462 of the first aerosol flow path 46, it flows through the first aerosol flow path 46 while further being aerosolized. The aerosol 72 thus generated is accommodated from the second end portion 462 of the first aerosol flow path 46, through the communication hole 33 provided in the bottom wall 32 of the capsule holder 30, and from the inlet portion 54 of the capsule 50. Introduced in room 53. According to the embodiment, before the aerosol 72 is introduced into the storage chamber 53, it flows through the second aerosol flow path 57 provided in the capsule 50, or the bottom wall of the capsule holder 30 and the bottom of the capsule 50. It flows through the space formed between them.

The aerosol 72 introduced from the inlet portion 54 into the containment chamber 53 was accommodated in the first space 531 when the containment chamber 53 flowed from the inlet portion 54 to the outlet portion 55 in the first direction X of the aerosol aspirator 1. By passing through the flavor source 52, the flavor component is added from the flavor source 52.

In this way, the aerosol 72 flows through the accommodation chamber 53 from the inlet portion 54 to the outlet portion 55 in the first direction X of the aerosol aspirator 1. Therefore, in the present embodiment, in the accommodation chamber 53, the flow direction of the aerosol 72 in which the aerosol 72 flows from the inlet portion 54 to the outlet portion 55 is the cylindrical axial direction of the capsule 50, and the first direction X of the aerosol aspirator 1 is X. It has become.

Further, when the aerosol aspirator 1 is used, the second load 34 provided in the capsule holder 30 generates heat and heats the heating region 53A of the storage chamber 53. As a result, the flavor source 52 housed in the first space 531 of the storage room 53 and the aerosol 72 flowing through the heating region 53A of the storage room 53 are heated.

Experiments have shown that in the aerosol aspirator 1, in order to increase the amount of flavor component added to the aerosol, it is effective to increase the amount of aerosol generated from the aerosol source 71 and raise the temperature of the flavor source 52. I know it. The phenomenon that the amount of flavor component added to the aerosol increases when the amount of aerosol generated from the aerosol source 71 increases is because the larger the amount of aerosol, the more the flavor component accompanied by the aerosol when passing through the aerosol source 52. I can explain. The phenomenon that the amount of flavor components added to the aerosol increases as the temperature of the flavor source 52 increases is that the higher the temperature of the flavor source 52, the easier it is for the flavor source 52 and the flavor added to the flavor source 52 to accompany the aerosol. Can be explained from.

Here, the adsorption of the menthol 80 to the flavor source 52 inside the capsule 50 will be described in detail. The tobacco granules 521 constituting the flavor source 52 are sufficiently larger than the molecules of menthol 80 and function as an adsorbent for menthol 80, which is an adsorbent. The menthol 80 is adsorbed on the tobacco granules 521 by chemisorption and is adsorbed on the tobacco granules 521 by physical adsorption. Chemisorption can occur by covalent bonding between the outermost electrons in the molecules that make up the tobacco granules 521 and the outermost electrons in the molecules that make up the menthol 80. Physical adsorption can occur due to van der Waals forces acting between the surface of the tobacco granules 521 and the surface of the menthol 80. As the amount of menthol 80 adsorbed on the tobacco granules 521 increases, the tobacco granules 521 and the menthol 80 enter a state called an adsorption equilibrium state. In the adsorption equilibrium state, the amount of menthol 80 newly adsorbed on the tobacco granules 521 and the amount of menthol 80 desorbed from the tobacco granules 521 are equal. That is, even if the menthol 80 is newly supplied to the tobacco granules 521, the apparent adsorption amount does not change. Not limited to the tobacco granules 521 and the menthol 80, the amount of adsorption in the adsorption equilibrium state decreases as the temperature of the adsorbent and the adsorbent increases. Both chemical adsorption and physical adsorption proceed in a form in which the menthol 80 occupies the adsorption site at the interface of the tobacco granules 521, and the adsorption amount of the menthol 80 when the adsorption site is completely filled is called the saturated adsorption amount. It will be easily understood that the adsorption amount in the adsorption equilibrium state described above is less than the saturated adsorption amount.

As described above, in general, the higher the temperature of the flavor source 52, the lower the amount of menthol 80 adsorbed on the tobacco granules 521 in the state of adsorption equilibrium between the tobacco granules 521 and the menthol 80. Therefore, when the flavor source 52 is heated by the second load 34 and the temperature rises, the amount of menthol 80 adsorbed on the tobacco granules 521 decreases, and a part of the menthol 80 adsorbed on the tobacco granules 521 is removed. Release.

Then, the aerosol 72 including the aerosolized menthol 80 derived from the aerosol source 71 and the aerosolized menthol 80 derived from the flavor source 52 flows through the second space 532 and is discharged from the outlet portion 55 to the outside of the accommodation chamber 53. It is supplied from the mouthpiece 58 into the user's mouth.

(Details of power supply unit)
Next, the details of the power supply unit 10 will be described with reference to FIG. As shown in FIG. 6, in the power supply unit 10, the DC / DC converter 66, which is an example of a voltage converter capable of converting the output voltage of the power supply 61 and applying it to the first load 45, has a cartridge 40 in the power supply unit 10. In the mounted state, it is connected between the first load 45 and the power supply 61. The MCU 63 is connected between the DC / DC converter 66 and the power supply 61. The second load 34 is connected between the MCU 63 and the DC / DC converter 66 with the cartridge 40 mounted on the power supply unit 10. As described above, in the power supply unit 10, the series circuit of the DC / DC converter 66 and the first load 45 and the second load 34 are connected in parallel to the power supply 61 in the state where the cartridge 40 is mounted.

The DC / DC converter 66 is a booster circuit that is controlled by the MCU 63 and can boost the input voltage (for example, the output voltage of the power supply 61) to output, and applies the input voltage or the boosted voltage to the first load 45. It is configured to be possible. Since the power supplied to the first load 45 can be adjusted by changing the voltage applied to the first load 45 by the DC / DC converter 66, the amount of the aerosol source 71 vaporized or atomized by the first load 45. Can be controlled. As the DC / DC converter 66, for example, a switching regulator that converts an input voltage into a desired output voltage can be used by controlling the on / off time of the switching element while monitoring the output voltage. When a switching regulator is used as the DC / DC converter 66, the input voltage can be output as it is without boosting by controlling the switching element. The DC / DC converter 66 is not limited to the step-up type (boost converter) described above, but may be a step-down type (back converter) or a buck-boost type. The DC / DC converter 66 may be used, for example, to set the voltage applied to the first load 45 to V1 to V5 [V], which will be described later.

Since the MCU 63 controls the discharge to the second load 34 by using a switch (not shown), the temperature of the second load 34, the temperature of the flavor source 52, or the temperature of the storage chamber 53 (that is, the second temperature T2 described later). ) Can be obtained. Further, the MCU 63 is preferably configured so that the temperature of the first load 45 can be acquired. The temperature of the first load 45 can be used to suppress overheating of the first load 45 and the aerosol source 71, and to highly control the amount of the aerosol source 71 vaporized or atomized by the first load 45.

The voltage sensor 671 measures and outputs a voltage value applied to the first load 45. The current sensor 672 measures and outputs the value of the current flowing through the first load 45. The output of the voltage sensor 671 and the output of the current sensor 672 are input to the MCU 63, respectively. The MCU 63 acquires the resistance value of the first load 45 based on the output of the voltage sensor 671 and the output of the current sensor 672, and acquires the temperature of the first load 45 based on the acquired resistance value of the first load 45. .. Specifically, for example, the voltage sensor 671 and the current sensor 672 may be composed of an operational amplifier and an analog-to-digital converter. At least a part of the voltage sensor 671 and / or at least a part of the current sensor 672 may be provided inside the MCU 63.

If a constant current is applied to the first load 45 when acquiring the resistance value of the first load 45, the current sensor 672 is unnecessary in the first temperature detection element 67. Similarly, if a constant voltage is applied to the first load 45 when acquiring the resistance value of the first load 45, the voltage sensor 671 is unnecessary in the first temperature detection element 67.

The voltage sensor 681 measures and outputs a voltage value applied to the second load 34. The current sensor 682 measures and outputs the value of the current flowing through the second load 34. The output of the voltage sensor 681 and the output of the current sensor 682 are input to the MCU 63, respectively. The MCU 63 acquires the resistance value of the second load 34 based on the output of the voltage sensor 681 and the output of the current sensor 682, and acquires the temperature of the second load 34 based on the acquired resistance value of the second load 34. ..

Here, the temperature of the second load 34 does not exactly match the temperature of the flavor source 52 heated by the second load 34, but can be regarded as substantially the same as the temperature of the flavor source 52. Further, the temperature of the second load 34 does not exactly match the temperature of the storage chamber 53 of the capsule 50 heated by the second load 34, but is considered to be substantially the same as the temperature of the storage chamber 53 of the capsule 50. Can be done. Therefore, the second temperature detection element 68 can also be used as a temperature detection element for detecting the temperature of the flavor source 52 or the temperature of the storage chamber 53 of the capsule 50. Specifically, for example, the voltage sensor 681 and the current sensor 682 may be composed of an operational amplifier and an analog-to-digital converter. At least a part of the voltage sensor 681 and / or at least a part of the current sensor 682 may be provided inside the MCU 63.

If a constant current is passed through the second load 34 when the resistance value of the second load 34 is acquired, the current sensor 682 is unnecessary in the second temperature detection element 68. Similarly, if a constant voltage is applied to the second load 34 when acquiring the resistance value of the second load 34, the voltage sensor 681 is unnecessary in the second temperature detection element 68.

Even if the second temperature detection element 68 is provided in the capsule holder 30 or the cartridge 40, the temperature of the second load 34, the temperature of the flavor source 52, or the storage chamber 53 of the capsule 50 is based on the output of the second temperature detection element 68. However, it is preferable that the second temperature detecting element 68 is provided in the power supply unit 10 having the lowest replacement frequency in the aerosol aspirator 1. In this way, the manufacturing cost of the capsule holder 30 and the cartridge 40 can be reduced, and the capsule holder 30 and the cartridge 40, which are frequently replaced as compared with the power supply unit 10, can be provided to the user at a low cost.

FIG. 7 is a diagram showing a specific example of the power supply unit 10 shown in FIG. FIG. 7 shows a specific example of a configuration in which the second temperature detection element 68 does not have the current sensor 682 and the first temperature detection element 67 does not have the current sensor 672.

As shown in FIG. 7, the power supply unit 10 includes a power supply 61, an MCU 63, an LDO regulator 65, a switch SW1, a series circuit of a resistance element R1 and a switch SW2 connected in parallel to the switch SW1. A parallel circuit C2 including a parallel circuit C1, a switch SW3, a series circuit of a resistance element R2 and a switch SW4 connected in parallel to the switch SW3, an operational capacitor OP1 and an analog digital converter ADC1 constituting a voltage sensor 671. And an operational switch OP2 and an analog-digital converter ADC2 constituting the voltage sensor 681. At least one of the operational amplifier OP1 and the operational amplifier OP2 may be provided inside the MCU 63.

The resistance element described in the present specification may be an element having a fixed electric resistance value, for example, a resistor, a diode, a transistor, or the like. In the example of FIG. 7, the resistance element R1 and the resistance element R2 are resistors, respectively.

The switch described in the present specification is a switching element such as a transistor that switches between interruption and continuity of a wiring path, and is, for example, a bipolar transistor such as an insulated gate bipolar transistor (IGBT) or metal oxidation. It can be an electric field effect transistor such as a film semiconductor electric field effect transistor (MOSFET: Metal-Oxide-Semicondutor Field-Effective Transistor). Further, the switch described in this specification may be configured by a relay (relay). In the example of FIG. 7, the switches SW1 to SW4 are transistors, respectively.

The LDO regulator 65 is connected to the main generatrix LU connected to the positive electrode of the power supply 61. The MCU 63 is connected to the LDO regulator 65 and the main negative bus LD connected to the negative electrode of the power supply 61. The MCU 63 is also connected to each of the switches SW1 to SW4, and controls the opening and closing of these switches. The LDO regulator 65 steps down the voltage from the power supply 61 and outputs the voltage. The output voltage V0 of the LDO regulator 65 is also used as the operating voltage of each of the MCU 63, the DC / DC converter 66, the operational amplifier OP1, the operational amplifier OP2, and the notification unit 16. Instead, at least one of the MCU 63, the DC / DC converter 66, the operational amplifier OP1, the operational amplifier OP2, and the notification unit 16 may use the output voltage of the power supply 61 itself as the operating voltage. Alternatively, at least one of the MCU 63, the DC / DC converter 66, the operational amplifier OP1, the operational amplifier OP2, and the notification unit 16 uses a voltage output by a regulator (not shown) different from the LDO regulator 65 as an operating voltage. May be good. The output voltage of this regulator may be different from or the same as V0.

(MCU)
Next, the function of the MCU 63 will be described. The MCU 63 includes a temperature detection unit, a power control unit, and a notification control unit as functional blocks realized by the processor executing a program stored in the ROM.

The temperature detection unit acquires the first temperature T1, which is the temperature of the first load 45, based on the output of the first temperature detection element 67. Further, the temperature detection unit acquires the temperature of the second load 34, the temperature of the flavor source 52, or the temperature of the storage chamber 53, that is, the second temperature T2, based on the output of the second temperature detection element 68.

In the case of the circuit example shown in FIG. 7, the temperature detection unit controls the switch SW1, the switch SW3, and the switch SW4 in a cutoff state, and controls the DC / DC converter 66 so as to output a predetermined constant voltage. .. Further, the temperature detection unit acquires the output value (voltage value applied to the first load 45) of the analog-to-digital converter ADC1 in a state where the switch SW2 is controlled to be in a conductive state, and the temperature detection unit obtains the output value (voltage value applied to the first load 45) based on this output value. Acquire one temperature T1.

The non-inverting input terminal of the operational amplifier OP1 may be connected to the terminal on the DC / DC converter 66 side of the resistance element R1, and the inverting input terminal of the operational amplifier OP1 may be connected to the terminal on the switch SW2 side of the resistance element R1. .. In this case, the temperature detection unit controls the switch SW1, the switch SW3, and the switch SW4 in a cut-off state, and controls the DC / DC converter 66 so as to output a predetermined constant voltage. Further, the temperature detection unit acquires the output value (voltage value applied to the resistance element R1) of the analog-digital converter ADC1 in a state where the switch SW2 is controlled to be in a conductive state, and the first is based on this output value. The temperature T1 can be obtained.

Further, in the case of the circuit example shown in FIG. 7, the temperature detection unit controls the switch SW1, the switch SW2, and the switch SW3 in a cutoff state, and DC / DC (not shown) so as to output a predetermined constant voltage. Controls elements such as converters.

Further, the temperature detection unit acquires the output value (voltage value applied to the resistance element R2) of the analog-digital converter ADC2 in a state where the switch SW4 is controlled to be in a conductive state, and the second is based on this output value. The temperature T2 can be obtained.

The notification control unit controls the notification unit 16 so as to notify the user of various types of information. For example, when the notification control unit detects that it is time to replace the capsule 50, the notification control unit controls the notification unit 16 to give a capsule replacement notification prompting the replacement of the capsule 50. Further, when the notification control unit detects that it is time to replace the cartridge 40, the notification control unit controls the notification unit 16 so as to give a cartridge replacement notification prompting the replacement of the cartridge 40. Further, when the notification control unit detects that the remaining amount of the power supply 61 is low, the notification control unit controls the notification unit 16 so as to notify the replacement or charging of the power supply 61, or the control state by the MCU 63 at a predetermined timing. The notification unit 16 may be controlled to notify (for example, the discharge mode described later).

The power control unit discharges the power supply 61 to the first load 45 (hereinafter, also simply referred to as the discharge to the first load 45) and discharges the power supply 61 to the second load 34 (hereinafter, simply referred to as the second load). (Also referred to as discharge to 34) is controlled. For example, when the power supply unit 10 has the circuit configuration shown in FIG. 7, the power control unit puts the switch SW2, the switch SW3, and the switch SW4 in a cut-off state (that is, off) and puts the switch SW1 in a conductive state (that is, off). That is, by turning it on), discharge to the first load 45 can be realized. When the power supply unit 10 has the circuit configuration shown in FIG. 7, the power control unit shuts off the switch SW1, the switch SW2, and the switch SW4, and makes the switch SW3 conductive. Discharge to the second load 34 can be realized.

When the power control unit detects an aerosol generation request from the user based on the output of the intake sensor 62 (that is, when a suction operation is performed by the user), the power control unit discharges the first load 45 and the second load 34. .. As a result, the aerosol source 71 is heated by the first load 45 (that is, the aerosol is produced) and the flavor source 52 is heated by the second load 34 in response to the aerosol production request. At this time, the electric power control unit adds a flavor component amount (hereinafter, simply, flavor) added from the flavor source 52 to the aerosol (vaporized and / or atomized aerosol source 71) generated in response to the aerosol generation request. It is also referred to as a component amount. For example, the discharge to the first load 45 and the second load 34 is controlled so that _{the flavor component amount W flavor, which will be described later, converges to a predetermined target amount.} This target amount is a value that is appropriately determined. For example, the target range of the flavor component amount may be appropriately determined, and the median value in this target range may be set as the target amount. As a result, by converging the amount of the flavor component to the target amount, the amount of the flavor component can be converged to the target range having a certain range. A weight (for example, [mg]) may be used as a unit of the amount of the flavor component and the target amount.

By the way, as described above, the cartridge 40 mounted on the aerosol aspirator 1 includes a menthol type in which the aerosol source 71 includes menthol and a regular type in which the aerosol source 71 does not include menthol. Similarly, the capsule 50 attached to the aerosol aspirator 1 includes a menthol type in which the flavor source 52 contains menthol and a regular type in which the flavor source 52 does not contain menthol.

Therefore, the aerosol aspirator 1 is in a state where the menthol type cartridge 40 is attached and the menthol type capsule 50 is attached, in other words, both the aerosol source 71 and the flavor source 52 contain the menthol. Can take a state.

Further, the aerosol aspirator 1 may be in a state in which a menthol type cartridge 40 is attached and a regular type capsule 50 is attached, in other words, a state in which only the aerosol source 71 contains menthol.

The aerosol aspirator 1 may be equipped with a regular type cartridge 40 and a menthol type capsule 50, in other words, a state in which only the flavor source 52 contains menthol.

Further, the aerosol aspirator 1 is in a state where the regular type cartridge 40 is attached and the regular type capsule 50 is attached, in other words, both the aerosol source 71 and the flavor source 52 do not contain menthol. Can take a state.

In such an aerosol aspirator 1, discharge to the first load 45 and the second load 34 is performed depending on the target of the aerosol source 71 and the flavor source 52 containing (or not containing) menthol. Appropriate control is preferred. Therefore, the MCU 63 can determine (identify) whether or not the type of the cartridge 40 and the capsule 50 mounted on the aerosol aspirator 1, that is, each of the aerosol source 71 and the flavor source 52 contains menthol. It is configured. The determination as to whether or not menthol is contained in each of the aerosol source 71 and the flavor source 52 may be realized by using an arbitrary method. For example, as will be described later, the MCU 63 may determine whether or not each of the aerosol source 71 and the flavor source 52 contains menthol based on the operation performed on the operation unit 15.

Then, the electric power control unit discharges the first load 45 and the second load 34 based on the determination result (identification result) of whether or not each of the aerosol source 71 and the flavor source 52 contains menthol. Control. In this way, by controlling the discharge to the first load 45 and the second load 34 according to the target containing (or not containing) menthol among the aerosol source 71 and the flavor source 52, the discharge to the first load 45 and the second load 34 is controlled. Depending on the object containing (or not containing) the menthol, the discharge mode to the first load 45 and the second load 34 can be different. Thereby, the discharge to the first load 45 and the second load 34 can be appropriately controlled depending on the target containing (or not containing) the menthol.

For example, suppose that the aerosol aspirator 1 is in a state where both the aerosol source 71 and the flavor source 52 contain menthol (that is, both the cartridge 40 and the capsule 50 are menthol type). In this case, the power control unit controls the discharge to the first load 45 and the discharge to the second load 34 by the menthol mode. In this case, the discharge mode to the first load 45 in the menthol mode is different from the discharge mode to the first load 45 in the regular mode described later. For example, in the discharge mode to the first load 45 in the menthol mode in this case, the voltage applied to the first load 45 is gradually or continuously increased (that is, as described later with reference to FIG. 13B). It is supposed to change). This makes it possible to change the amount of aerosol produced by heating with the first load 45. Therefore, it is possible to highly control the amount of menthol derived from the aerosol source 71 and the amount of menthol derived from the flavor source 52.

Further, the discharge mode to the second load 34 in the menthol mode when both the aerosol source 71 and the flavor source 52 contain menthol is also different from the discharge mode to the second load 34 in the regular mode described later. It has become a thing. For example, in this case, the discharge mode to the second load 34 in the menthol mode gradually or continuously decreases (that is, changes) the target temperature of the second load 34, as will be described later using FIG. 13 (a). ). As a result, as will be described later, for example, even before the flavor source 52 (specifically, tobacco granules 521) and menthol in the capsule 50 reach the adsorption equilibrium state, the flavor source 52 and the menthol are in the adsorption equilibrium state. It is possible to supply an appropriate amount of menthol to the user and stabilize the menthol provided to the user to an appropriate amount even in the period after reaching the above.

Further, for example, it is assumed that the aerosol aspirator 1 is in a state in which menthol is contained only in the aerosol source 71 (that is, the cartridge 40 is a menthol type and the capsule 50 is a regular type). In this case as well, the power control unit controls the discharge to the first load 45 and the discharge to the second load 34 by the menthol mode. However, the discharge mode to the first load 45 in the menthol mode in this case is the discharge mode to the first load 45 in the menthol mode when both the aerosol source 71 and the flavor source 52 described above contain menthol. , And the mode of discharging to the first load 45 in the regular mode. For example, in the menthol mode in this case, the discharge mode to the first load 45 gradually or continuously reduces the voltage applied to the first load 45 (that is, as described later with reference to FIG. 14B). It is supposed to change). This makes it possible to change the amount of aerosol produced by heating with the first load 45. Therefore, it is possible to highly control the amount of menthol derived from the aerosol source 71 and the amount of menthol derived from the flavor source 52.

Further, the discharge mode to the second load 34 in the menthol mode when only the aerosol source 71 contains menthol is, for example, the menthol when both the aerosol source 71 and the flavor source 52 contain menthol. It is the same as the discharge mode to the second load 34 in the mode. That is, the discharge mode to the second load 34 in the menthol mode in this case gradually or continuously reduces (that is, changes) the target temperature of the second load 34 (FIG. 13 (a)). And (a) of FIG. 14). In other words, the discharge mode to the second load 34 in the menthol mode in this case is also different from the discharge mode to the second load 34 in the regular mode. As a result, even in this case, even before the flavor source 52 (specifically, tobacco granules 521) and the menthol in the capsule 50 reach the adsorption equilibrium state, the flavor source 52 and the menthol reach the adsorption equilibrium state. Even at a later time, it is possible to supply an appropriate amount of menthol to the user and stabilize the menthol provided to the user to an appropriate amount.

Further, for example, it is assumed that the aerosol aspirator 1 is in a state where both the aerosol source 71 and the flavor source 52 do not contain menthol (that is, both the cartridge 40 and the capsule 50 are regular types). In this case, the power control unit controls the discharge to the first load 45 and the discharge to the second load 34 in the regular mode. The discharge mode to the first load 45 in the regular mode is such that the voltage applied to the first load 45 is kept constant, for example, as will be described later using FIG. 13 (b). Thereby, in the case of the regular mode, the control of the voltage applied to the first load 45 (that is, the power supplied to the first load 45) can be simplified.

Further, in the discharge mode to the second load 34 in the regular mode, for example, as will be described later using FIG. 13A, the target temperature of the second load 34 is gradually or continuously increased (that is, changed). It is supposed to make you. Thereby, in the regular mode, the flavor component (that is, the flavor derived from the flavor source 52) that is reduced by the suction by the user can be compensated by raising the temperature of the second load 34 (that is, the flavor source 52). ..

Further, for example, it is assumed that the aerosol aspirator 1 is in a state in which menthol is contained only in the flavor source 52 (that is, the cartridge 40 is a regular type and the capsule 50 is a menthol type). In this case as well, the power control unit controls the discharge to the first load 45 and the discharge to the second load 34 by the menthol mode. However, in this case, the discharge mode to the first load 45 in the menthol mode includes the case where both the aerosol source 71 and the flavor source 52 described above contain menthol, and the case where only the aerosol source 71 contains menthol. It is different from the discharge mode to the first load 45 in the menthol mode in either case. For example, the discharge mode to the first load 45 in the menthol mode in this case is the same as the discharge mode to the first load 45 in the regular mode. That is, the discharge mode to the first load 45 in the menthol mode in this case keeps the voltage applied to the first load 45 constant. As a result, the amount of aerosol produced by heating by the first load 45 can be made constant, and the amount of menthol derived from the flavor source 52 generated by heating by the second load 34 can be easily controlled.

Further, the discharge mode to the second load 34 in the menthol mode when only the flavor source 52 contains menthol is also the case where both the aerosol source 71 and the flavor source 52 described above contain menthol. It is different from the discharge mode to the second load 34 in the menthol mode in either case where the aerosol source 71 contains only the menthol. For example, the discharge mode to the second load 34 in the menthol mode in this case is the same as the discharge mode to the second load 34 in the regular mode. That is, the discharge mode to the second load 34 in the menthol mode in this case gradually or continuously increases (that is, changes) the target temperature of the second load 34. As a result, the menthol adsorbed on the flavor source 52 (specifically, tobacco granules 521) can be gradually desorbed from the flavor source 52, and the amount of menthol provided to the user (that is, the flavor derived from menthol). Can be stabilized.

When the menthol is contained only in the flavor source 52, the power control unit may control the discharge to the first load 45 and the discharge to the second load 34 in the regular mode.

(Various parameters used to generate aerosols)
Before explaining the specific discharge control to the first load 45 and the like by the MCU 63, various parameters used for the discharge control to the first load 45 and the like by the MCU 63 will be described here.

The weight [mg] of the aerosol generated by heating by the first load 45 and passing through the flavor source 52 (that is, in the capsule 50) for one suction operation by the user is described _{as the aerosol weight Waerosol.} The electric power required to be supplied to the first load 45 in order to generate an aerosol having an aerosol weight of _{Waerosol is referred to as an atomizing electric power Priquid} . Further, the supply time of the atomizing power _Pliquid to the first load 45 is described _{as the supply time t sense.} In view of the overheating suppression and the like of the first load 45, the supply time _{t sense} a predetermined upper limit value _{t upper} (e.g. 2.4 [s]) is provided, MCU63, the supply time _{t sense} When the upper limit value _tupper is reached, the power supply to the first load 45 is stopped regardless of the output value of the intake sensor 62 (see steps S19 and S20 described later).

Further, the weight of the flavor component contained in the flavor source 52 when the _{user performs n puff} times (however, n _puff is a natural number of 0 or more) after the capsule 50 is attached to the aerosol aspirator 1. [Mg] is described as the remaining amount of flavor component W _capsule (n _puff). The weight of the flavor component contained in the flavor source 52 of a new capsule 50 (capsule 50 also suction operation once from being attached is not being performed) [mg], i.e. flavor components remaining _{W capsule (n puff} = 0) is also described as _Winitial.

Further, the weight [mg] of the flavor component added to the aerosol passing through the flavor source 52 (that is, in the capsule 50) for one suction operation by the user is described _{as the flavor component amount W flavor.} Then, the parameter relating to the temperature of the flavor source 52 is described _{as the temperature parameter T capsule.} The temperature parameter T _capsule is a parameter indicating the above-mentioned second temperature T2, and is, for example, a parameter indicating the temperature of the second load 34.

It has been experimentally found that the amount of flavor component W _flavor depends on the remaining amount of flavor component W _capsule , the temperature parameter T _capsule , and the aerosol weight _Waerosol. Therefore, the flavor component amount W _flavor can be modeled by the following formula (1).

W _flavor = β × (W _capsule × T _capsule ) × γ × W _aerosol ... (1)

Β in the above formula (1) is a coefficient indicating the ratio of how much flavor component is added to the aerosol when the generated aerosol passes through the flavor source 52 for one suction operation by the user. It is required experimentally. Further, γ in the above equation (1) is a coefficient obtained experimentally. _{The temperature parameter T capsule} and the remaining amount of flavor component W _capsule can fluctuate during the period in which one suction operation is performed, but in order to treat these as constant values, such γ is introduced here. There is.

The remaining amount of flavor component W _capsule decreases as the suction operation is performed by the user. Therefore, the remaining amount of flavor component W _capsule is inversely proportional to the number of times the suction operation is performed (hereinafter, also referred to as the number of times of suction). Further, in the aerosol suction device 1, since the discharge to the first load 45 is performed each time the suction operation is performed, the remaining amount of flavor component W _capsule is discharged to the first load 45 in order to generate the aerosol. It can be said that it is inversely proportional to the number of times the battery is discharged and the cumulative value of the period during which the first load 45 is discharged.

As can be seen from the above equation (1) _{, assuming that the aerosol weight Waerosol} generated for one suction operation by the user is controlled to be almost constant, in order to stabilize the _{flavor component amount W flavor. It is necessary to increase the temperature parameter T capsule} (that is, the temperature of the flavor source 52) as the remaining amount of flavor component W _capsule decreases (that is, the number of suctions increases).

Therefore, in the MCU63 (power control unit), when the cartridge 40 and the capsule 50 mounted on the aerosol aspirator 1 are of a regular type (that is, neither the aerosol source 71 nor the flavor source 52 contains menthol). In the case), the discharge mode for controlling the discharge to the first load 45 and the second load 34 is set to the regular mode. When the discharge mode is set to the regular mode, the MCU 63 controls the discharge to the second load 34 in order to raise the temperature of the flavor source 52 as the _{remaining amount of flavor component W capsule decreases (that is, the number of suctions increases).} (See FIGS. 13 and 14).

On the other hand, the MCU 63 (power control unit) is used when the cartridge 40 or capsule 50 mounted on the aerosol aspirator 1 is of the menthol type (that is, when the aerosol source 71 or the flavor source 52 contains menthol). Sets the discharge mode to a menthol mode different from the regular mode. When the discharge mode is set to the menthol mode, the MCU 63 adjusts _{the temperature of the flavor source 52 as the remaining amount of flavor component W capsule} decreases (that is, the number of suctions increases) from the viewpoint of supplying an appropriate amount of menthol to the user. In order to lower the load, the discharge to the second load 34 is controlled (see FIGS. 13 and 14). This makes it possible to supply the user with an appropriate amount of menthol, as described below.

By the way, if the temperature of the flavor source 52 is also lowered as the remaining amount of flavor component W _{capsule is reduced, the amount of flavor component W flavor} is reduced. Therefore, when the temperature of the flavor source 52 is lowered as the remaining amount of flavor component W _capsule decreases, the MCU 63 increases the voltage applied to the first load 45 to increase the electric power supplied to the first load 45. By doing so, the aerosol weight _Waerosol may be increased (see FIG. 13). _{As a result, the amount of flavor component W flavor} due to lowering the temperature of the flavor source 52 in order to supply an appropriate amount of menthol to the user is reduced by heating the aerosol weight _Waerosol by the first load 45. Since it can be compensated by an increase, it is possible _{to suppress a decrease in the amount of flavor component W flavor} supplied to the user's mouth and enable a stable supply of menthol and flavor component to the user.

(Operation of aerosol aspirator)
Next, an example of the operation of the aerosol aspirator 1 will be described with reference to FIGS. 8 to 12. The operation of the aerosol aspirator 1 described below is realized, for example, by the processor of the MCU 63 executing a program stored in advance in the memory 63a or the like.

As shown in FIG. 8, the MCU 63 waits until the power of the aerosol aspirator 1 is turned on by an operation to the operation unit 15 or the like (step S0: NO loop). When the power of the aerosol aspirator 1 is turned on (step S0: YES), the MCU 63 shifts the operating mode of the aerosol aspirator 1 to an activation mode capable of producing an aerosol, and types of the cartridge 40 and the capsule 50. The flavor identification process (described later) for identifying the above is executed (step S1).

The MCU 63 has a second load so that the target temperature of the second load 34 (hereinafter, _{also referred to as the target temperature T cap_target} ), which will be described later, converges to a predetermined temperature (default temperature) when the transition to the start mode is triggered. The discharge to 34 may be started. As a result, the second load 34 can be preheated with the transition to the start mode, and the temperatures of the second load 34 and the flavor source 52 can be raised at an early stage. For example, from the viewpoint of securing the amount of menthol that can be supplied to the user, in the menthol mode, the initial target temperature T _{cap_target} is set to a higher 80 [° C.], as will be described later. It takes a certain amount of time for the second load 34 to reach such a high temperature, but by preheating the second load 34 triggered by the transition to the start mode, the second load 34 reaches such a high temperature. You can encourage early arrival. Therefore, when the aerosol source 71 or the like contains menthol, the amount of menthol provided to the user (that is, the flavor derived from menthol) is stabilized at an early stage, and immediately after the transition to the activation mode (for example, so-called sucking). From the beginning), it becomes possible to stably supply an appropriate amount of menthol to the user.

Further, the MCU 63 discharges the second load 34 before executing the flavor identification process, that is, before executing the determination as to whether or not each of the aerosol source 71 and the flavor source 52 contains menthol. You may want to start. As a result, the timing at which the preheating of the second load 34 is started can be advanced, and the temperatures of the second load 34 and the flavor source 52 can be raised at an early stage. Further, when the discharge to the second load 34 is started before the flavor identification process is executed in this way, when the flavor identification process is executed, the MCU 63 includes menthol in each of the aerosol source 71 and the flavor source 52 (that is, each of the aerosol source 71 and the flavor source 52). When the determination as to whether or not the load is performed is executed), the preheating of the second load 34 is terminated. After that, the MCU 63 may start discharging to the second load 34 according to the target containing (or not containing) menthol among the aerosol source 71 and the flavor source 52. As a result, after it is determined whether or not the aerosol source 71 and the flavor source 52 contain menthol, it is possible to appropriately control the discharge to the second load 34 according to the target.

Further, when preheating the second load 34 as a trigger of the transition to the start mode, the MCU 63 sets the target temperature (predetermined temperature) of the second load 34 at the time of preheating with the aerosol source 71 and the flavor source 52, for example. Less than the minimum target temperature of the second load 34 (60 [° C.] in this embodiment) in the menthol mode when both of them contain menthol and when only the aerosol source 71 contains menthol. Let it be the temperature. As a result, the second load 34 and the flavor source 52 can be prevented from becoming too hot due to the preheating of the second load 34, and the second load 34 can be preheated to an appropriate temperature, stabilizing the flavor and taste and the second load. It is possible to reduce power consumption by preheating 34. Specifically, even if menthol is contained in both the aerosol source 71 and the flavor source 52, or only in the aerosol source 71, the flavor source 52 becomes too hot due to the preheating of the second load 34, and the flavor taste is enjoyed. It is possible to prevent the user from being supplied with a large amount of menthol, which can lead to a decrease in the amount of menthol.

Further, when preheating the second load 34 as a trigger of the transition to the start mode, the MCU 63 sets the target temperature of the second load 34 at the time of preheating to the minimum of the target temperature of the second load 34 in the regular mode, for example. The temperature is less than the value (30 [° C.] in this embodiment). Further, even when the menthol is contained only in the flavor source 52, the discharge to the second load 34 is controlled in the same discharge mode as in the regular mode. Therefore, in other words, the MCU 63 is the target of the second load 34 at the time of preheating. The temperature is set to a temperature lower than the minimum value of the target temperature of the second load 34 when the menthol is contained only in the flavor source 52. As a result, even if both the aerosol source 71 and the flavor source 52 do not contain menthol, or even if only the flavor source 52 contains menthol, the preheating of the second load 34 causes the second load 34 and flavor. It is possible to suppress the source 52 from becoming too hot, preheat the second load 34 to an appropriate temperature, stabilize the aroma, and reduce the power consumption due to the preheating of the second load 34. Specifically, even if both the aerosol source 71 and the flavor source 52 do not contain menthol, or even if only the flavor source 52 contains menthol, the flavor source 52 is preheated by the second load 34. It is possible to prevent the user from being supplied with a large amount of flavor components and menthol which may lead to a decrease in flavor and taste due to excessively high temperature.

By the way, in the present embodiment, as will be described later, the minimum value of the target temperature of the second load 34 in the regular mode is the case where both the aerosol source 71 and the flavor source 52 contain menthol, and the aerosol source 71. The temperature is lower than the minimum target temperature of the second load 34 in the menthol mode when only the menthol is contained. Therefore, by setting the target temperature of the second load 34 during preheating to a temperature lower than the minimum value of the target temperature of the second load 34 in the regular mode, menthol is naturally provided to both the aerosol source 71 and the flavor source 52. The temperature is less than the minimum target temperature of the second load 34 in the menthol mode when it is contained and when the aerosol source 71 contains only the menthol. Therefore, by setting the target temperature of the second load 34 during preheating to a temperature lower than the minimum value of the target temperature of the second load 34 in the regular mode, the menthol of the aerosol source 71 and the flavor source 52 is included. Regardless of the target (or not included), it is possible to prevent the second load 34 and the flavor source 52 from becoming too hot due to the preheating of the second load 34, thereby stabilizing the flavor and taste. And the power consumption can be reduced by preheating the second load 34.

Next, the MCU 63 determines whether or not the cartridge 40 or the capsule 50 is a menthol type based on the processing result of the flavor identification process (step S2). For example, when it is set that the cartridge 40 or the capsule 50 is a menthol type as a processing result of the flavor identification process, the MCU 63 determines affirmative in step S2 (step S2: YES), and the first load from the power supply 61. In order to control the discharge to the 45 and the second load 34 by the menthol mode, the menthol mode process is executed.

In the menthol mode processing, the MCU 63 first notifies the user of the menthol mode by the notification unit 16 (step S3). At this time, the MCU 63 notifies that the menthol mode is set by, for example, causing the light emitting element 161 to emit green light and vibrating the vibrating element 162.

Then, MCU63, based on the flavor components remaining _{W capsule} contained in the flavor source 52 _{(n puff} -1), and the target temperature _{T Cap_target,} atomizing power supplied to the first load 45 (hereinafter, atomization power set also referred) and the P _liquid (step S4), and processing proceeds to step S5. Here, flavor components remaining _{W capsule (n puff} -1) is, _{W initial} next if not performed even suction operation once after the mounting of the capsule 50 of the new, if suction operation is only to take place more than once _{The remaining amount of flavor component W capsule} (n _puff ) calculated by the immediately preceding remaining amount update process (described later) is obtained. Specific setting examples of the target temperature T _{cap_target and the} like in the menthol mode will be described later with reference to FIGS. 13 and 14.

Next, the MCU 63 acquires the current temperature of the second load 34 (hereinafter, _{also referred to as temperature T cap_sense} ) based on the output of the second temperature detection element 68 (step S5). _{The temperature T cap_sense,} which is the temperature of the second load 34, is an example of the temperature parameter T _{capsule described above.} Here, an example in which the temperature of the second load 34 is used as the temperature parameter T _capsule will be described, but the temperature of the flavor source 52 or the storage chamber 53 may be used instead of the temperature of the second load 34. good.

Then, MCU63, the control and the target temperature _{T Cap_target} set, based on the obtained temperature _{T Cap_sense,} as the temperature _{T Cap_sense} converges to the target temperature _{T Cap_target,} the discharge from the power source 61 to the second load 34 (Step S6). At this time, MCU63, as the temperature _{T Cap_sense} converges to the target temperature _{T Cap_target,} for example perform PID (Proportional-Integral-Differential) control.

_Further , as a control for converging the temperature T _{cap_sense} to the target temperature T cap_target, instead of the PID control, ON / OFF control for turning on / off the power supply to the second load 34, P (Proportional) control, or PI (Proportional). -Integral) control or the like may be used. Further, the target temperature T _{cap_target} may have hysteresis.

Next, the MCU 63 determines whether or not there is a request for aerosol production (step S7). If there is no aerosol production request (step S7: NO), the MCU 63 determines whether a predetermined period has elapsed without an aerosol production request (step S8). If the predetermined period has not elapsed without the aerosol production request (step S8: NO), the MCU 63 returns to step S6.

When the predetermined period elapses without the aerosol generation request (step S8: YES), the MCU 63 stops discharging to the second load 34 (step S9), and the operating mode of the aerosol aspirator 1 is changed to the sleep mode. The transition is made (step S10), and the process proceeds to step S29 described later. Here, the sleep mode is an operation mode in which the power consumption of the aerosol aspirator 1 is smaller than that in the activation mode and the transition to the activation mode is possible. Therefore, the MCU 63 can reduce the power consumption of the aerosol aspirator 1 while maintaining a state in which the aerosol aspirator 1 can be returned to the start mode as needed by shifting the aerosol aspirator 1 to the sleep mode.

On the other hand, if there is a request for aerosol generation (step S7: YES), the MCU 63 temporarily stops heating the flavor source 52 by the second load 34 (that is, discharging to the second load 34), and the second temperature detection element. Based on the output of 68, the temperature T _{cap_sense} is acquired (step S11). The MCU 63 does not have to stop the heating of the flavor source 52 by the second load 34 (that is, the discharge to the second load 34) when the step S11 is executed.

Then, the MCU 63 _{determines whether or not the acquired temperature T cap_sense} is higher than the set target temperature T _{cap_target} −δ (where δ ≧ 0) (step S12). This δ can be arbitrarily determined by the manufacturer of the aerosol aspirator 1. If the temperature _{T Cap_sense} is higher than the target temperature _{T cap_target -δ} (step S12: YES), MCU63 sets current atomization power _{P liquid} - [delta (but delta> 0) as a new atomizing power _{P liquid} (Step S13), the process proceeds to step S16.

Details will be described later with reference to FIG. 13 and the like, but in the present embodiment, _{when the target temperature T cap_target} is controlled by the menthol mode, the MCU 63 sets the target temperature T _{cap_target} from 80 [° C.] to 60 at a predetermined time. Change to [℃]. Immediately after such a change of the target temperature T _{cap_target , the temperature T cap_sense} (for example, 80 [° C.]), which is the temperature of the second load 34 at that time, _{is the changed target temperature T cap_target} (that is, 60 [° C.]]. ) May be exceeded. In such a case, MCU63 performs a positive determination in step S12, so that the reducing atomizing power _{P liquid} by executing the processing in step S13. As a result, the actual temperature of the flavor source 52, the second load 34, etc. may be higher than 60 [° C.] immediately after _{the target temperature T cap_target is changed from 80 [° C.] to 60 [° C.].} However, the atomizing power _Pliquid can be reduced to reduce the amount of the aerosol source 71 generated by heating by the first load 45 and supplied to the flavor source 52. Therefore, it is possible to suppress the supply of a large amount of menthol into the mouth of the user, and to stably supply an appropriate amount of menthol to the user.

On the other hand, be higher than the temperature _{T Cap_sense} the target temperature _{T cap_target -δ} (step S12: NO), MCU63 determines whether or not the temperature _{T Cap_sense} is lower than the target temperature _{T cap_target -δ} (step S14) .. If the temperature _{T Cap_sense} is lower than the target temperature _{T cap_target -δ} (step S14: YES), MCU63 sets the current atomization power _{P liquid} + delta as a new atomizing power _{P liquid} (step S15), and step S16 Proceed to.

On the other hand, if there is no temperature _{T Cap_sense} is lower than the target temperature _{T cap_target -δ} (step S14: NO), since the temperature _{T cap_sense} = target temperature _{T cap_target -δ,} MCU63 is maintained current atomization power _{P liquid} Then, the process proceeds to step S16 as it is.

Next, the MCU 63 notifies the user of the current discharge mode (step S16). For example, in the case of the menthol mode (that is, when the menthol mode process is executed), in step S16, the MCU 63 notifies the user that the menthol mode is in effect, for example, by causing the light emitting element 161 to emit green light. On the other hand, in the case of the regular mode (that is, when the regular mode processing is executed), in step S16, the MCU 63 notifies the user that the mode is the regular mode by, for example, causing the light emitting element 161 to emit light in white.

Then, MCU63 controls the DC / DC converter 66 as atomized power _{P liquid} set in step S13 or S15 is supplied to the first load 45 (step S17). Specifically, MCU63, by controlling the voltage applied to the first load 45 by the DC / DC converter 66, so that atomizing power _{P liquid} is supplied to the first load 45. As a result, the atomizing power _Liquid is supplied to the first load 45, the aerosol source 71 is heated by the first load 45, and the vaporized and / or atomized aerosol source 71 is generated.

Next, the MCU 63 determines whether or not the aerosol production request has been completed (step S18). When the aerosol generation request is not completed (step S18: NO), the MCU 63 determines whether or not the elapsed time from the start of supply of the _{atomizing power Liquid , that is, the supply time t sense has reached the upper} limit value t upper. Is determined (step S19). If the supply time t _{sense has not reached the upper} limit value tupper (step S19: NO), the MCU 63 returns to step S16. _{In this case, the supply of the atomizing power Liquid} to the first load 45, that is, the vaporization and / or the generation of the atomized aerosol source 71 is continued.

On the other hand, when the aerosol generation request is completed (step S18: YES) and when the supply time t _{sense reaches the upper} limit value tupper (step S19: YES), the MCU 63 is the atomizing power to the first load 45. The supply of the P _liquid (that is, the discharge to the first load 45) is stopped (step S20), and the remaining amount update process for calculating the remaining amount of the flavor component contained in the flavor source 52 is executed.

In the remaining amount updating processing, MCU63 first acquires the supply time _{t sense} that supplied the atomizing power _{P liquid} (step S21). Next, the MCU 63 adds "1" to _{n puff} , which is the count value of the puff number counter (step S22).

Then, the MCU 63 has the acquired supply time t _{sense , the atomizing power Liquid} supplied to the first load 45 in response to the aerosol generation request, and the target temperature T _{cap_target set when the aerosol generation request is detected.} , The remaining amount of flavor component W _capsule (n _puff ) contained in the flavor source 52 is updated (step S23). MCU63, for example, by storing calculates the flavor components remaining _{W capsule (n puff)} from the following equation (2), the calculated flavor components remaining _{W capsule} the _{(n puff)} in the memory 63a, flavor components remaining The quantity W _capsule (n _puff ) is updated.

Β and γ in the above formula (2) are the same as β and γ in the above formula (1), and are obtained experimentally. Further, δ in the above formula (2) is the same as δ used in step S13, and is preset by the manufacturer of the aerosol aspirator 1. Then, α in the above equation (2) is a coefficient obtained experimentally like β and γ.

Then, MCU63 determines the updated flavor components remaining _{W capsule (n puff)} is whether it is less than the predetermined remaining amount threshold which is a condition for capsules exchange notification (step S24). If the updated flavor components remaining _{W capsule (n puff)} or higher battery level threshold (step S24: NO), (in other words the capsule 50) which contained as the flavor source 52 flavor components are still in the well Therefore, the MCU 63 proceeds to step S29 as it is.

On the other hand, if the updated flavor components remaining _{W capsule (n puff)} is less than the battery level threshold (step S24: YES), since the flavor components contained in the flavor source 52 is considered to have almost disappeared, the MCU63, cartridge It is determined whether or not the capsule 50 has been replaced a predetermined number of times after the replacement of the 40 (step S25). For example, in the present embodiment, one cartridge 40 is provided to the user in the form of combining five capsules 50. In this case, in step S25, the MCU 63 determines whether the capsule 50 has been replaced five times after the cartridge 40 has been replaced.

If the capsule 50 has not been replaced a predetermined number of times after the cartridge 40 has been replaced (step S25: NO), it is considered that the cartridge 40 is still usable, so the MCU 63 gives a capsule replacement notification (step S26). ). For example, the MCU 63 notifies the capsule exchange by operating the notification unit 16 in the operation mode for the capsule exchange notification.

On the other hand, if the capsule 50 is replaced a predetermined number of times after the cartridge 40 is replaced (step S25: YES), it is considered that the life of the cartridge 40 has been reached, so the MCU 63 gives a cartridge replacement notification (step S27). .. For example, the MCU 63 notifies the cartridge replacement by operating the notification unit 16 in the operation mode for the cartridge replacement notification.

Next, the MCU 63 resets the count value of the puff number counter to 1, and initializes the setting of the _{target temperature T cap_target (step S28).} In initializing the setting of the target temperature T _{cap_target} , the MCU 63 sets, for example, the target temperature T _{cap_target} to -273 [° C.], which is absolute zero. As a result, the discharge to the second load 34 can be substantially stopped and the heating of the flavor source 52 by the second load 34 can be stopped regardless of the temperature of the second load 34 at that time.

Next, the MCU 63 determines whether or not the power of the aerosol aspirator 1 has been turned off by an operation or the like on the operation unit 15 (step S29). Then, when the power of the aerosol aspirator 1 is turned off (step S29: YES), the MCU 63 ends a series of processes. On the other hand, if the power of the aerosol aspirator 1 is not turned off (step S29: NO), the MCU 63 returns to step S1.

Further, when it is set that the cartridge 40 and the capsule 50 are regular types as the processing result of the flavor identification process in step S1, the MCU 63 determines negative in step S2 (step S2: NO) and starts from the power supply 61. In order to control the discharge to the first load 45 and the second load 34 by the regular mode, the regular mode processing is executed.

In the regular mode processing, the MCU 63 first notifies the user that it is in the regular mode by the notification unit 16 (step S30). At this time, the MCU 63 notifies that it is in the regular mode by, for example, causing the light emitting element 161 to emit white light and vibrating the vibrating element 162.

Next, the MCU 63 determines the _{aerosol weight Waerosol} required to achieve the target flavor component amount W _{flavor based on the flavor component remaining amount W capsule} (n _puff -1) contained in the flavor source 52 (. Step S31). _{In step S31, for example, the MCU 63 calculates the aerosol weight Waerosol} from the following formula (3) obtained by modifying the above formula (1), and determines the calculated aerosol weight _Waerosol.

Β and γ in the above formula (3) are the same as β and γ in the above formula (1), and are obtained experimentally. Further, in the above formula (3), the target flavor component amount W _flavor is preset by the manufacturer of the aerosol aspirator 1. The flavor components remaining in the above equation _{(3) W capsule (n puff} -1) is, _{W initial} next if not performed even suction operation once after the mounting of the capsule 50 is new, the suction operation once If the above is performed, the remaining amount of flavor component W _capsule (n _puff ) calculated by the immediately preceding remaining amount update process is obtained.

Then, MCU63, based on the aerosol weight _{W designation Aerosol} determined in step S31, it sets the atomizing power _{P liquid} supplied to the first load 45 (step S32). In step S32, MCU63, for example, calculates the atomization power _{P liquid} from the following equation (4), sets the atomizing power _{P liquid} calculated.

The α in the above formula (4) is the same as the α in the above formula (2), and is obtained experimentally. Aerosol weight _{W designation Aerosol} in the above equation (4) is a aerosol weight _{W designation Aerosol} determined in step S31. Then, t in equation (4) above is the supply time _{t sense} prospective supplying atomization power _{P liquid,} may be, for example, the upper limit value _{t upper.}

Next, the MCU 63 _{determines whether or not the atomizing power Liquid} determined in step S32 is equal to or less than a predetermined upper limit power that can be discharged from the power source 61 to the first load 45 at that time (step S33). If atomization power _{P liquid} is the upper limit power less (step S33: Yes), MCU63 is returned to step S6 mentioned above. On the other hand, if the atomizing power _{P liquid} exceeds the upper limit electric power (step S33: NO), MCU63 is to increase the target temperature _{T Cap_target} predetermined amount (step S34), and returns to step S30.

That is, as can be seen from the above-mentioned equation (1), _{by increasing the target temperature T cap_target} (that is, T _{capsule ), the aerosol weight Waerosol} required to achieve the target flavor component amount W _flavor is reduced by that amount. As a result, the atomizing power _Pliquid determined in step S32 above can be reduced. By repeating steps S31 to S34, the MCU 63 can make the determination of step S33 initially determined to be NO to be determined to be YES, and can shift to step S5 shown in FIG.

(Flavor identification process)
Next, the flavor identification process shown in step S1 will be described. As shown in FIG. 12, in the flavor identification process, the MCU 63 first determines whether or not the aerosol aspirator 1 has just been turned on (step S41). The MCU 63 determines affirmation in step S41 only in the case of the first flavor identification process after the power of the aerosol aspirator 1 is turned on, for example.

The MCU 63 then attempts to obtain the types of cartridge 40 and capsule 50 (step S42). The MCU 63 can obtain the types of cartridge 40 and capsule 50, for example, based on the operations performed on the operating unit 15. Further, the cartridge 40 and the capsule 50 are provided with a storage medium (for example, an IC chip) that stores information indicating these types, and the MCU 63 reads the information stored in the storage medium to read the information stored in the storage medium, thereby storing the cartridge 40 and the capsule. You may get 50 types. Further, the electric resistance values of the cartridge 40 and the capsule 50 are set to be different according to these types, and the MCU 63 may acquire the types of the cartridge 40 and the capsule 50 based on these electric resistance values. good. Further, instead of the electric resistance value, the type of the cartridge 40 and the capsule 50 may be obtained by using other detectable physical quantities such as the light transmittance and the reflectance of the capsule 50 and the cartridge 40.

Next, the MCU 63 determines whether or not the types of the cartridge 40 and the capsule 50 have been acquired in step S42 (step S43). If the types of the cartridge 40 and the capsule 50 can be acquired (step S43: YES), the MCU 63 stores the information indicating the types of the cartridge 40 and the capsule 50 acquired in step S42 in the memory 63a (step S44). Then, the MCU 63 sets the types of the cartridge 40 and the capsule 50 obtained in step S42 as the processing result of the flavor identification processing this time, and ends the flavor identification processing.

On the other hand, if the types of the cartridge 40 and the capsule 50 cannot be obtained (step S43: NO), the MCU 63 performs a predetermined error process (step S45) and ends the flavor identification process. When the types of the cartridge 40 and the capsule 50 cannot be obtained, for example, the cartridge 40 is not sufficiently attached (connected) to the power supply unit 10, or the capsule 50 is not sufficiently accommodated in the capsule holder 30. Can occur in some cases. Further, the operation unit 15 is not operated, the information stored in the storage medium of the cartridge 40 or the capsule 50 cannot be read by the MCU 63, the electric resistance value of the cartridge 40 or the capsule 50, the light transmittance or the reflection. Even if the rate shows an outlier, the MCU 63 cannot obtain the type of cartridge 40 and capsule 50.

Further, if it is determined that the aerosol suction device 1 is not immediately after the power is turned on (step S41: NO), the MCU 63 determines whether or not the cartridge 40 or the capsule 50 has been attached / detached (step S46). If the cartridge 40 or the capsule 50 has been attached / detached (step S46: YES), these types may have been changed, so the MCU 63 proceeds to step S42 described above to move the cartridge 40 and the capsule 50 to the cartridge 40 and the capsule 50. Try to get the type.

On the other hand, if the cartridge 40 and the capsule 50 have not been attached / detached (step S46: NO), there is no change in these types, so that the MCU 63 is information indicating the types of the cartridge 40 and the capsule 50 stored in the memory 63a. Is read. Then, the MCU 63 sets the types of the cartridge 40 and the capsule 50 indicated by the information read in step S47 as the processing result of the flavor identification processing this time, and ends the flavor identification processing.

The MCU 63 may detect the attachment / detachment of the cartridge 40 and the capsule 50 by any method.

For example, the MCU 63 has an electric resistance value between the pair of discharge terminals 12 acquired by using the voltage sensor 671 and the current sensor 672, and an electric resistance value between the pair of discharge terminals 17 acquired by using the voltage sensor 681 and the current sensor 682. The attachment / detachment of the cartridge 40 may be detected based on the electric resistance value. A state in which the pair of discharge terminals 12 are conducted by connecting the first load 45 between the pair of discharge terminals 12, and a state in which the first load 45 is not connected between the pair of discharge terminals 12 and the pair of discharge terminals 12 are air. It will be clear that the electric resistance values between the discharge terminals 12 that can be acquired by the MCU 63 are different in each of the states insulated by. Therefore, the MCU 63 can detect the attachment / detachment of the cartridge 40 based on the electric resistance value between the discharge terminals 12.

Similarly, a state in which the pair of discharge terminals 17 are conducted by connecting the second load 34 between the pair of discharge terminals 17, and a pair of discharge terminals in which the second load 34 is not connected between the pair of discharge terminals 17. It will be clear that the electrical resistance values between the discharge terminals 17 that can be acquired by the MCU 63 are different in each of the states where 17 is insulated by air. Therefore, the MCU 63 can detect the attachment / detachment of the cartridge 40 based on the electric resistance value between the discharge terminals 17.

Further, the MCU 63 includes fluctuations (fluctuations) in the electric resistance value between the pair of discharge terminals 12 acquired by using the voltage sensor 671 and the current sensor 672, and a pair of paired discharge terminals acquired by using the voltage sensor 681 and the current sensor 682. The attachment / detachment of the capsule 50 may be detected based on the fluctuation of the electric resistance value between the discharge terminals 17. For example, when the capsule 50 is attached and detached, stress is applied to the discharge terminal 12 and the discharge terminal 17 due to the attachment and detachment of the capsule 50. This stress causes fluctuations in the electric resistance value between the pair of discharge terminals 12 and the electric resistance value between the pair of discharge terminals 17. Therefore, the MCU 63 can detect the attachment / detachment of the capsule 50 based on the fluctuation of the electric resistance value between the discharge terminals 12 and the fluctuation of the electric resistance value between the discharge terminals 17.

Further, the MCU 63 may detect the attachment / detachment of the cartridge 40 or the capsule 50 based on the information stored in the storage medium provided in the cartridge 40 or the capsule 50. For example, when the information stored in these storage media transitions from a state in which acquisition (reading) is possible to a state in which acquisition is not possible, the MCU 63 detects the removal of the cartridge 40 and the capsule 50. Further, when the information stored in these storage media transitions from the unacquirable state to the acquireable state, the MCU 63 detects the attachment of the cartridge 40 or the capsule 50.

Further, identification information (ID) for identifying each cartridge 40 or capsule 50 is stored in a storage medium provided on the cartridge 40 or capsule 50, and the MCU 63 bases the cartridge 40 or capsule 50 on the basis of this identification information. You may detect the attachment and detachment of. In this case, the MCU 63 detects the attachment / detachment (in this case, replacement) of the cartridge 40 or the capsule 50 when the identification information of the cartridge 40 or the capsule 50 changes.

Further, the MCU 63 may detect the attachment / detachment of the cartridge 40 or the capsule 50 based on the light transmittance or the reflectance of the cartridge 40 or the capsule 50. For example, when the light transmittance or reflectance of the cartridge 40 or the capsule 50 changes from the value indicating the attachment to the value indicating the removal, the MCU 63 detects the removal of the cartridge 40 or the capsule 50. Further, when the light transmittance or reflectance of the cartridge 40 or the capsule 50 changes from the value indicating the removal to the value indicating the attachment, the MCU 63 detects the attachment of the cartridge 40 or the capsule 50.

(Specific control example when the cartridge 40 and the capsule 50 are menthol type)
Next, refer to FIG. 13 for a specific control example by the MCU 63 when both the cartridge 40 and the capsule 50 are of the menthol type (that is, when both the aerosol source 71 and the flavor source 52 contain menthol). explain. Here, from the time when the new capsule 50 is attached to the aerosol aspirator 1 until the remaining amount of the flavor component in the capsule 50 becomes less than the above-mentioned remaining amount threshold value (that is, the remaining amount of the flavor component in the capsule 50 is almost the same). It will be described as assuming that the suction operation is performed a predetermined number of times (until it disappears). Further, it is assumed that a sufficient amount of the aerosol source 71 is stored in the cartridge 40 while the suction operation is performed a predetermined number of times.

In each of (a), (b), and (c) of FIG. 13, the horizontal axis indicates the remaining amount of flavor component [mg] (that is, the remaining amount of flavor component W _capsule ) contained in the flavor source 52 in the capsule 50. ing. _{The vertical axis in FIG. 13A shows the target temperature (that is, the target temperature T cap_target} ) [° C.] of the second load 34, which is a heater for heating the capsule 50 (that is, the flavor source 52). The vertical axis in FIG. 13B shows the voltage [V] applied to the first load 45, which is a heater for heating the aerosol source 71 stored in the cartridge 40.

Further, the vertical axis on the left side in FIG. 13C shows the amount of menthol [mg / puff] supplied to the user's mouth by one suction operation. The vertical axis on the right side in FIG. 13C shows the amount of flavor component [mg / puff] supplied to the user's mouth by one suction operation. The amount of menthol supplied to the user's mouth by one suction operation is also hereinafter referred to as a unit supply menthol amount. Further, the amount of flavor component supplied to the user's mouth by one suction operation is also hereinafter referred to as a unit supply flavor component amount.

In FIG. 13, the first period Tm1 is a fixed period immediately after the capsule 50 is replaced. Specifically, the first period Tm1 is a period from when the remaining amount of the flavor component in the capsule 50 _{is Winter} to when it becomes _Th1 preset by the manufacturer of the aerosol aspirator 1. _{Here, W th1 is} smaller than _{W initial,} and is a value larger than the _{W th2} is the above-mentioned battery level threshold as the condition for capsules exchange notice. For example, W _th1 can be the remaining amount of the flavor component when the suction operation is performed about 10 times after the new capsule 50 is attached. Further, in FIG. 13, the second period Tm2 is a period after the first period Tm1, specifically, the period from when the remaining amount of the flavor component in the capsule 50 becomes W _th1 to when it becomes _{W th2.} be.

When both the cartridge 40 and the capsule 50 are of the menthol type, as described above, the MCU 63 controls the discharge to the first load 45 and the second load 34 by the menthol mode. Specifically, in the menthol mode in this case, as shown by the thick solid line in FIG. 13 (a), the MCU 63 sets the target temperature of the second load 34 in the first period Tm1 to 80 [° C.]. ..

In this case, the target temperature (80 [° C.]) of the second load 34 in the first period Tm1 is higher than the melting point of menthol (for example, 42 to 45 [° C.]) and the boiling point of menthol (for example, 212 to 216). It is a temperature lower than [° C]). Further, the target temperature of the second load 34 in the first period Tm1 in this case may be a temperature of 90 [° C.] or less. Thereby, in the present embodiment, the temperature of the second load 34 (that is, the flavor source 52) is controlled to converge to 80 [° C.] in the first period Tm1. Therefore, in the first period Tm1, the menthol adsorbed on the flavor source 52 is heated to an appropriate temperature by the second load 34, so that the rapid desorption of the menthol from the flavor source 52 can be suppressed. An appropriate amount of menthol can be stably supplied to the user.

Then, in the menthol mode in which both the cartridge 40 and the capsule 50 are of the menthol type, when the subsequent second period Tm2 is reached, the MCU 63 sets the target temperature of the second load 34 as the target in the immediately preceding first period Tm1. It is set to 60 [° C.], which is lower than the temperature. The target temperature (60 [° C.]) of the second load 34 in the second period Tm2 in this case is also, for example, a temperature higher than the melting point of menthol and lower than the boiling point of menthol. Further, the target temperature of the second load 34 in the second period Tm2 in this case may also be a temperature of 90 [° C.] or less. Thereby, in the present embodiment, the temperature of the second load 34 (that is, the flavor source 52) is controlled to converge to 60 [° C.] in the second period Tm2. Therefore, even in the second period Tm2, the menthol adsorbed on the flavor source 52 is heated to an appropriate temperature by the second load 34, so that the rapid desorption of the menthol from the flavor source 52 can be suppressed. , An appropriate amount of menthol can be stably supplied to the user.

As described above, in the menthol mode when both the cartridge 40 and the capsule 50 are menthol type, the target temperature of the second load 34 is reduced from 80 [° C.] to 60 [° C.] in two steps. ing. That is, in the menthol mode when both the cartridge 40 and the capsule 50 are of the menthol type, in the first period Tm1, discharge to the second load 34 having a target temperature of 80 [° C.] is performed, and the second The temperature of the load 34 (that is, the flavor source 52) is controlled to converge to a higher temperature of around 80 [° C.]. Then, in the subsequent second period Tm2, discharge is performed to the second load 34 having a target temperature of 60 [° C.], and the temperature of the second load 34 (that is, the flavor source 52) is 60 [° C.], which is lower. It is controlled to converge to the vicinity.

Further, in the menthol mode when both the cartridge 40 and the capsule 50 are of the menthol type, as shown by the thick solid line in FIG. 13 (b), the MCU 63 is applied to the first load 45 in the first period Tm1. The applied voltage is V1 [V]. This V1 [V] is a voltage preset by the manufacturer of the aerosol aspirator 1. As a result, in the first period Tm1 in this case, electric power corresponding to the applied voltage V1 [V] is supplied from the power source 61 to the first load 45, and an amount of vaporized and / or atomized aerosol source corresponding to this electric power is supplied. 71 is generated by the first load 45.

Then, in the menthol mode in which the cartridge 40 and the capsule 50 are both menthol type, the MCU 63 sets the voltage applied to the first load 45 to V2 [V] in the subsequent second period Tm2. This V2 [V] has a higher voltage than V1 [V] as shown in FIG. 13 (b). V2 [V] is preset by the manufacturer of the aerosol aspirator 1. The MCU 63 can apply a voltage such as V1 [V] or V2 [V] to the first load 45 by controlling the DC / DC converter 66, for example.

As described above, in the menthol mode in which the cartridge 40 and the capsule 50 are both menthol type, the voltage applied to the first load 45 is increased from V1 [V] to V2 [V] in two steps. It has become. That is, in the menthol mode when both the cartridge 40 and the capsule 50 are of the menthol type, during the first period Tm1, the applied voltage is set to a lower V1 [V] and the discharge to the first load 45 is performed. Then, in the subsequent second period Tm2, the applied voltage is set to a higher V2 [V] and discharged to the first load 45, and a power larger than that of the immediately preceding first period Tm1 is supplied to the first load 45. NS. As a result, the amount of the vaporized and / or atomized aerosol source 71 generated by the first load 45 also increases from the immediately preceding first period Tm1.

FIG. 13 shows an example of the unit supply menthol amount when the cartridge 40 and the capsule 50 are both menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above menthol mode. It is shown in the unit supply menthol amount 131a in (c).

Further, an example of the unit supply flavor component amount when both the cartridge 40 and the capsule 50 are menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above menthol mode is , The unit-supplied flavor component amount 131b in (c) of FIG. 13 is shown.

In order to compare with the unit supply menthol amount 131a and the unit supply flavor component amount 131b, even though the cartridge 40 and the capsule 50 are both menthol type, the MCU 63 discharges to the first load 45 and the second load 34 ( That is, an example in which the target temperature of the second load 34 and the voltage applied to the first load 45) are controlled by the regular mode will be described.

In the regular mode, as shown by the thick broken line in FIG. 13 (a), the MCU 63 sets the target temperature of the second load 34 in the first period Tm1 and the second period Tm2, for example, 30 [° C.]. The temperature is gradually increased in multiple stages, such as 60 [° C.], 70 [° C.], 85 [° C.], at least as compared with the menthol mode when the aerosol source 71 contains menthol. In other words, the number of steps to change (decrease) the target temperature of the second load 34 in the menthol mode, at least when the aerosol source 71 contains menthol, changes (increases) the target temperature of the second load 34 in the regular mode. ) Is smaller than the number of steps to be made.

That is, in a system such as the regular mode in which the target temperature of the second load 34 (that is, the flavor source 52) is gradually increased, it is easy to follow the target temperature of these actual temperatures, so that the target temperature is finely switched. Therefore, it becomes possible to provide the user with a stable flavor component (that is, a flavor derived from the flavor source 52). On the other hand, in a system such as the menthol mode in which the target temperature of the second load 34 (that is, the flavor source 52) is gradually reduced, it is difficult to follow the target temperature of these actual temperatures. Therefore, by reducing the switching of the target temperature, it is possible to suppress the occurrence of a situation in which the actual temperature and the target temperature deviate from each other. The target temperature of the second load 34 and the timing for changing the target temperature in the regular mode are set in advance by the manufacturer of the aerosol aspirator 1. As another example, the timing of changing the target temperature of the second load 34 in the regular mode is from the remaining amount of flavor component [mg] (that is, the remaining amount of flavor component W _capsule ) contained in the flavor source 52 in the capsule 50. It may be decided.

For example, here, the maximum value of the target temperature of the second load 34 in the first period Tm1 of the regular mode (here, 70 [° C.]) is the target temperature of the second load 34 in the first period Tm1 of the menthol mode (here). The temperature is lower than 80 [° C.]). The minimum value of the target temperature of the second load 34 in the second period Tm2 of the regular mode (here, 70 [° C.]) is the target temperature of the second load 34 in the second period Tm2 of the menthol mode (here, 60 [° C.]). ℃]), the temperature is higher than that.

Further, in the regular mode, as shown by the thick broken line in FIG. 13B, the MCU 63 sets the voltage applied to the first load 45 in the first period Tm1 and the second period Tm2 to a constant V3 [V. ] To maintain. This V3 [V] is a voltage higher than V1 [V] and lower than V2 [V], and is a voltage preset by the manufacturer of the aerosol aspirator 1. The MCU 63 can apply a voltage such as V3 [V] to the first load 45 by controlling the DC / DC converter 66, for example.

FIG. 13 shows an example of the unit supply menthol amount when the cartridge 40 and the capsule 50 are both menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above regular mode. It is shown in the unit supply menthol amount 132a in (c).

Further, an example of the unit supply flavor component amount when both the cartridge 40 and the capsule 50 are menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above regular mode is , The unit-supplied flavor component amount 132b in (c) of FIG. 13 is shown.

That is, even when both the cartridge 40 and the capsule 50 are menthol type, the discharge to the first load 45 and the second load 34 (that is, the target temperature of the second load 34 and the applied voltage to the first load 45) is performed by the regular mode. ) Is controlled. In this case, since the target temperature of the second load 34 in the first period Tm1 is lower than that in the case where these are controlled by the menthol mode, the temperature of the flavor source 52 in the first period Tm1 is lower.

Therefore, when the cartridge 40 and the capsule 50 are both menthol type and the discharge to the first load 45 or the like is controlled by the regular mode, the flavor source 52 (in detail) is contained in the capsule 50 as compared with the case where the cartridge 40 and the capsule 50 are controlled by the menthol mode. It takes a long time for the tobacco granules 521) and menthol to reach an adsorption equilibrium state. During this time, most of the menthol derived from the aerosol source 71 is adsorbed on the flavor source 52, and the number of menthols that can pass through the flavor source 52 decreases.

From the above, when the cartridge 40 and the capsule 50 are both menthol type and the discharge to the first load 45 or the like is controlled by the regular mode, the unit supply menthol is compared with the case where the cartridge 40 and the capsule 50 are both controlled by the menthol mode as described above. As shown in the amount 131a and the unit supply menthol amount 132a, the unit supply menthol amount that can be supplied to the user in the first period Tm1 decreases. Therefore, in this way, there is a possibility that a sufficient amount of menthol cannot be supplied to the user in the first period Tm1.

On the other hand, in the menthol mode when both the cartridge 40 and the capsule 50 are of the menthol type, the MCU 63 is in the period before the flavor source 52 (specifically, tobacco granules 521) and the menthol reach the adsorption equilibrium state. In the first period Tm1 assumed to be, the second load 34 (that is, the flavor source 52) is set to a higher temperature near 80 [° C.]. Thereby, the MCU 63 can promote the flavor source 52 (specifically, the tobacco granules 521) and the menthol to reach the adsorption equilibrium state at an early stage in the capsule 50 in the first period Tm1, and is derived from the aerosol source 71. By suppressing the menthol from adsorbing to the flavor source 52, it is possible to secure the amount of menthol supplied to the user's mouth without adsorbing to the flavor source 52 among the menthols derived from the aerosol source 71. Further, the MCU 63 is desorbed from the flavor source 52 (specifically, tobacco granules 521) and supplied into the user's mouth by heating the second load 34 (that is, the flavor source 52) to a high temperature in the first period Tm1. Menthol derived from the flavor source 52 can also be increased. Therefore, as shown in the unit supply menthol amount 131a, a sufficient amount of menthol can be supplied to the user from the time when the flavor component contained in the flavor source 52 is sufficient (when new).

In addition, in FIG. 13C, the unit supply menthol amount 133a is a unit supply when both the cartridge 40 and the capsule 50 are menthol type and the flavor source 52 is not heated by the second load 34. An example of the amount of menthol is shown. In this case, the temperature of the second load 34 (that is, the flavor source 52) in the first period Tm1 becomes room temperature (see RT in FIG. 13C). Therefore, even in this case, as shown in the unit supply menthol amount 133a, the temperature of the flavor source 52 in the first period Tm1 is higher than that in the case where the discharge to the first load 45 or the like is controlled by the menthol mode. Due to its low value, a sufficient amount of menthol cannot be supplied to the user during the first period Tm1.

By the way, in order to supply a sufficient amount of menthol to the user in the first period Tm1, in the menthol mode when both the cartridge 40 and the capsule 50 are menthol type, the target of the second load 34 in the first period Tm1. I try to set the temperature high. However, if the flavor source 52, which has become hot after the first period Tm1, is continuously heated at a higher temperature even in the second period Tm2, a large amount of menthol may be supplied to the user, which may lead to a decrease in flavor and taste.

Therefore, as described above, in the menthol mode when both the cartridge 40 and the capsule 50 are menthol type, the target temperature of the second load 34 in the second period Tm2 is set to the second load 34 in the first period Tm1. By lowering the temperature below the target temperature of Tm2, it is possible to prevent the flavor source 52, which has become hot after the first period Tm1, from being continuously heated at a high temperature even in the second period Tm2. As a result, as shown in the unit supply menthol amount 131a, in the second period Tm2, which is assumed to be the period after the flavor source 52 (specifically, tobacco granules 521) and the menthol reach the adsorption equilibrium state, the flavor source By lowering the temperature of 52, the amount of menthol that can be adsorbed on the flavor source 52 (specifically, tobacco granules 521) can be increased, and an increase in the amount of unit-supplied menthol can be suppressed. Therefore, in the second period Tm2, it is possible to supply an appropriate amount of menthol to the user.

Further, in order to suppress the supply of a large amount of menthol to the user in the second period Tm2, in the menthol mode when both the cartridge 40 and the capsule 50 are menthol type, the second load in the second period Tm2. The target temperature of 34 is set low. However, when the target temperature of the second load 34 is set low in this way, the increase in the unit supply menthol amount in the second period Tm2 can be suppressed, but the unit supply flavor component amount in the second period Tm2 also decreases, which is sufficient for the user. It is conceivable that it will not be possible to provide a good sensation.

Therefore, in the menthol mode in which both the cartridge 40 and the capsule 50 are of the menthol type, that is, when the flavor source 52 also contains the menthol in addition to the aerosol source 71, the MCU 63 has the first load 45 in the first period Tm1. The voltage applied to the first load 45 is V1 [V], and the voltage applied to the first load 45 in the subsequent second period Tm2 is V2 [V] higher than V1 [V]. As a result, the second period is Tm2, and the voltage applied to the first load 45 can be changed to a higher V2 [V] in accordance with changing the target temperature of the second load 34 to a lower 60 [° C.]. Therefore, in the second period Tm2, the amount of the aerosol source 71 generated by heating by the first load 45 and supplied to the flavor source 52 can be increased, and as shown in the unit supply flavor component amount 131b, the first It is possible to suppress a decrease in the amount of flavor component supplied per unit in Tm2 for 2 periods.

(Specific control example when only the cartridge 40 is a menthol type)
Next, a specific control example by the MCU 63 when only the cartridge 40 is of the menthol type (that is, when only the aerosol source 71 contains the menthol) will be described with reference to FIG. In the menthol mode when only the cartridge 40 is a menthol type, only the voltage applied to the first load 45 in the first period Tm1 and the second period Tm2 is the case where both the cartridge 40 and the capsule 50 are menthol type. It is different from the menthol mode of. Therefore, in the following, the description will be focused on the parts different from the description of FIG. 13, and the description of the parts similar to the description of FIG. 13 will be omitted as appropriate.

In the menthol mode when only the cartridge 40 is a menthol type, as shown by the thick solid line in FIG. 14 (b), the MCU 63 sets the voltage applied to the first load 45 in the first period Tm1 to V4 [ V]. This V4 [V] is a voltage higher than V3 [V] as shown in FIG. 14 (b), and is a voltage preset by the manufacturer of the aerosol aspirator 1. As a result, in the first period Tm1 in this case, electric power corresponding to the applied voltage V3 [V] is supplied from the power source 61 to the first load 45, and an amount of vaporized and / or atomized aerosol source corresponding to this electric power is supplied. 71 is generated by the first load 45.

Then, in the menthol mode in which only the cartridge 40 is a menthol type, the MCU 63 sets the voltage applied to the first load 45 to V5 [V] in the subsequent second period Tm2. As shown in FIG. 14 (b), this V5 [V] is a voltage higher than V3 [V] and lower than V4 [V]. V5 [V] is preset by the manufacturer of the aerosol aspirator 1. The MCU 63 can apply a voltage such as V4 [V] or V5 [V] to the first load 45 by controlling the DC / DC converter 66, for example.

As described above, in the menthol mode when only the cartridge 40 is a menthol type, the voltage applied to the first load 45 is reduced from V4 [V] to V5 [V] in two steps. .. That is, in the menthol mode when only the cartridge 40 is a menthol type, during the first period Tm1, the applied voltage is set to a higher V4 [V] and the discharge to the first load 45 is performed. Then, in the subsequent second period Tm2, the applied voltage is set to a lower V5 [V] and discharged to the first load 45, and less power than the immediately preceding first period Tm1 is supplied to the first load 45. NS. As a result, the amount of the aerosol source 71 (vaporized and / or atomized aerosol source 71) generated by heating by the first load 45 and supplied to the flavor source 52 is also reduced from the immediately preceding first period Tm1.

An example of the unit supply menthol amount when only the cartridge 40 is a menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above menthol mode is shown in FIG. 14 (c). ) Is shown in the unit supply menthol amount 141a.

An example of the unit supply flavor component amount when only the cartridge 40 is a menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above menthol mode is shown in FIG. It is as shown in the unit supply flavor component amount 141b in c).

Further, only the cartridge 40 is a menthol type, and an example of the unit supply menthol amount when the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above regular mode is shown in FIG. It is shown in the unit supply menthol amount 142a in (c).

An example of the unit supply flavor component amount when only the cartridge 40 is a menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above regular mode is shown in FIG. It is as shown in the unit supply flavor component amount 142b in c).

Further, an example of the unit supply menthol amount when only the cartridge 40 is a menthol type and the flavor source 52 is not heated by the second load 34 is shown in the unit supply menthol amount 143a in FIG. 14 (c). It will be shown.

An example of the unit-supplied flavor component amount when only the cartridge 40 is a menthol type and the flavor source 52 is not heated by the second load 34 is shown in the unit-supplied flavor component amount 143b in FIG. 14 (c). It will be shown.

That is, in the menthol mode when only the cartridge 40 is a menthol type, that is, when the flavor source 52 does not contain menthol, the MCU 63 sets the voltage applied to the first load 45 in the first period Tm1 to V4 [. V], and the voltage applied to the first load 45 in the subsequent second period Tm2 is V5 [V], which is lower than V4 [V]. As a result, in the first period Tm1, which is assumed to be the period before the flavor source 52 (specifically, tobacco granules 521) and the menthol reach the adsorption equilibrium state in the capsule 50, the first load 45 is higher than V4 [V ] Is applied (that is, a large amount of electric power is supplied to the first load 45) to increase the amount of the aerosol source 71 generated by heating by the first load 45 and supplied to the flavor source 52.

Therefore, in the period before the flavor source 52 and the menthol reach the adsorption equilibrium state, the amount of menthol supplied into the user's mouth without adsorbing to the flavor source 52 among the menthol derived from the aerosol source 71 can be increased. , The flavor source 52 and the menthol can be promoted to reach the adsorption equilibrium state at an early stage in the capsule 50. Therefore, as shown in the unit supply menthol amount 141a, an appropriate and sufficient amount of menthol is stabilized for the user from a time when the flavor component contained in the flavor source 52 is sufficient (for example, so-called start of sucking). Can be supplied.

(Specific control example when only the capsule 50 is a menthol type)
Next, a specific control example by the MCU 63 when only the capsule 50 is a menthol type (that is, when only the flavor source 52 contains menthol) will be described with reference to FIG. In the following, the description will be focused on the parts different from the description of FIG. 13, and the description of the parts similar to the description of FIG. 13 will be omitted as appropriate.

As described above, in the menthol mode in which only the capsule 50 is a menthol type, the MCU 63 controls the discharge to the first load 45 and the second load 34 in the same discharge mode as in the regular mode. Specifically, in the menthol mode in this case, as shown by the thick solid line in FIG. 15 (a), the MCU 63 sets the target temperature of the second load 34 in the first period Tm1 and the second period Tm2. For example, the temperature is gradually increased in multiple stages (here, 4 stages) such as 30 [° C.], 60 [° C.], 70 [° C.], and 85 [° C.]. Further, in the menthol mode in this case, as shown by the thick solid line in FIG. 15B, the MCU 63 keeps the applied voltage to the first load 45 in the first period Tm1 and the second period Tm2 constant. Maintain at V3 [V].

An example of the unit supply menthol amount when only the capsule 50 is a menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above menthol mode is shown in FIG. 15 (c). ) Is shown in the unit supply menthol amount 151a.

An example of the unit supply flavor component amount when only the capsule 50 is a menthol type and the MCU 63 controls the target temperature of the second load 34 and the voltage applied to the first load 45 by the above menthol mode is shown in FIG. It is as shown in the unit supply flavor component amount 151b in c).

Further, an example of the unit supply menthol amount when only the capsule 50 is a menthol type and the flavor source 52 is not heated by the second load 34 is shown in the unit supply menthol amount 153a in FIG. 15 (c). It will be shown.

An example of the unit-supplied flavor component amount when only the capsule 50 is a menthol type and the flavor source 52 is not heated by the second load 34 is shown in the unit-supplied flavor component amount 153b in FIG. 15 (c). It will be shown.

In the menthol mode when only the capsule 50 is a menthol type, that is, when only the flavor source 52 contains menthol, the MCU 63 sets the target temperature of the second load 34 in the first period Tm1 and the second period Tm2. By increasing the temperature step by step, the temperature of the second load 34 (that is, the flavor source 52) can be gradually increased. As a result, the menthol adsorbed on the flavor source 52 (specifically, tobacco granules 521) in the capsule 50 can be gradually desorbed from the flavor source 52. That is, a sufficient amount of menthol can be stably supplied to the user from a time when the remaining amount of flavor component W _{capsule is sufficient (for example, so-called start of sucking).} In other words, the amount of menthol provided to the user (that is, the flavor derived from menthol) can be stabilized.

As described above, according to the power supply unit 10, the discharge to the first load 45 and the second load 34 can be appropriately controlled depending on the target including (or not including) the menthol.

Although one embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the claims, which naturally belong to the technical scope of the present invention. Understood. In addition, each component in the above embodiment may be arbitrarily combined as long as the gist of the invention is not deviated.

For example, in the present embodiment, at least in the menthol mode when the aerosol source 71 contains a menthol, the voltage applied to the first load 45 is changed stepwise in two steps, but the present invention is not limited to this. 2. It may be changed stepwise in multiple steps rather than two steps, or it may be changed continuously.

Further, for example, in the present embodiment, at least in the menthol mode when the aerosol source 71 contains menthol, the target temperature of the second load 34 is changed stepwise in two steps, but the present invention is limited to this. Instead, the temperature may be changed stepwise or continuously in more than two steps (however, in less steps than in the regular mode). Similarly, in the regular mode as well, the target temperature of the second load 34 may be changed stepwise or continuously in multiple steps rather than four steps.

Further, for example, in the present embodiment, the target temperature of the second load 34 at the time of preheating the second load 34, which is triggered by the transition to the start mode, is set to the minimum of the target temperature of the second load 34 in the menthol mode and the regular mode. Although it is less than the value, it is not limited to this. For example, the target temperature of the second load 34 at the time of preheating the second load 34, which is triggered by the transition to the start mode, may be set to a temperature equal to or higher than the minimum value of the target temperature of the second load 34 in the regular mode. In other words, the target temperature of the second load 34 at the time of preheating may be set to a temperature equal to or higher than the minimum value of the target temperature of the second load 34 in the menthol mode when only the flavor source 52 contains menthol. In this way, when the menthol is contained only in the flavor source 52, the temperature of the second load 34 can be lowered to an appropriate target temperature by stopping the preheating of the second load 34. .. Further, at least when the aerosol source 71 contains menthol, it is possible to easily reach the temperature of the second load 34 to an appropriate target temperature by supplying more electric power to the second load 34. can. Therefore, regardless of the target containing (or not containing) menthol, it is possible to easily bring the second load 34 to an appropriate target temperature according to the target. ..

Further, for example, in the present embodiment, the heating chamber 43 of the cartridge 40 and the storage chamber 53 of the capsule 50 are physically separated from each other and communicate with each other by the aerosol flow path 90. The heating chamber 43 and the accommodating chamber 53 do not necessarily have to be physically separated from each other. The heating chamber 43 and the accommodating chamber 53 may be insulated from each other and communicate with each other. Even in this case, since the heating chamber 43 and the accommodation chamber 53 are insulated from each other, the accommodation chamber 53 can be made less susceptible to the heat generated by the first load 45 of the heating chamber 43. As a result, the menthol is suppressed from being rapidly desorbed by the flavor source 52, so that the menthol can be stably supplied to the user. Further, the heating chamber 43 and the accommodating chamber 53 are physically separated from each other and are insulated from each other, and may communicate with each other.

Further, for example, the overall shape of the aerosol aspirator 1 is not limited to the shape in which the power supply unit 10, the cartridge 40, and the capsule 50 are arranged in a row as shown in FIG. The aerosol aspirator 1 may have any shape such as a substantially box shape as long as the cartridge 40 and the capsule 50 are interchangeably configured with respect to the power supply unit 10.

Further, for example, the cartridge 40 may have a configuration integrated with the power supply unit 10.

Further, for example, the capsule 50 may be configured to be replaceable with respect to the power supply unit 10, and may be detachable from the power supply unit 10.

Further, for example, in the present embodiment, the first load 45 and the second load 34 are heaters that generate heat by the electric power discharged from the power source 61, but the first load 45 and the second load 34 are from the power source 61. It may be a Perche element capable of both heat generation and cooling depending on the electric power to be discharged. When the first load 45 and the second load 34 are configured in this way, the degree of freedom in controlling the temperature of the aerosol source 71 and the temperature of the flavor source 52 is widened, so that the unit flavor amount can be controlled to a higher degree.

Further, for example, in the present embodiment, the MCU 63 controls the discharge from the power source 61 to the first load 45 and the second load 34 so that the amount of the flavor component converges to the target amount. Is not limited to one specific value, and may be a range having a certain width.

Further, for example, in the present embodiment, the MCU 63 controls the discharge from the power source 61 to the second load 34 so that the temperature of the flavor source 52 converges to the target temperature, but the target temperature is specified. It is not limited to one value of, and may be a range having a certain width.

It is possible to determine whether or not each of the aerosol source and the flavor source contains menthol.
In the first state in which it is determined that only the flavor source of the aerosol source and the flavor source contains menthol, the discharge mode to the first heater is such that the menthol is contained in both the aerosol source and the flavor source. The mode of discharging to the first heater in the second state determined to be contained, and the first state in the third state determined that only the aerosol source among the aerosol source and the flavor source contains menthol. Unlike the discharge mode to the heater
And / or, the discharge mode to the second heater in the first state is different from the discharge mode to the second heater in the second state and the discharge mode to the second heater in the third state.

According to (2), when menthol is contained only in the flavor source, the target temperature of the second heater or the flavor source is gradually or continuously increased. As a result, the menthol adsorbed on the flavor source can be gradually desorbed from the flavor source, and the amount of menthol provided to the user (that is, the flavor derived from menthol) can be stabilized.

As a result, in these cases, the amount of menthol that can be adsorbed on the flavor source is reduced by setting the target temperature to a higher temperature before the flavor source and the menthol reach the adsorption equilibrium state (for example, at the beginning of sucking). , It is possible to suppress the adsorption of menthol derived from an aerosol source to a flavor source. Therefore, at this time, it is possible to secure the amount of menthol supplied to the user without adsorbing to the flavor source among the menthol derived from the aerosol source. Further, in these cases, in the subsequent period (for example, after the flavor source and the menthol reach the adsorption equilibrium state), the target temperature is set to a lower temperature to increase the amount of menthol that can be adsorbed to the flavor source, and the aroma is increased. It is possible to suppress the supply of a large amount of menthol, which can lead to a decrease in taste, to the user. From the above, the menthol provided to the user can be stabilized to an appropriate amount.

Further, according to (4), when both the aerosol source and the flavor source contain menthol, the voltage applied to the first heater is changed stepwise or continuously. Thereby, the amount of aerosol produced by heating by the first heater can be changed, and the amount of menthol derived from the aerosol source and the amount of menthol derived from the flavor source can be highly controlled.
