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

<<1. Configuration example of suction device>>
A suction device is a device that produces a substance that is suctioned by a user. In the following description, it is assumed that the substance produced by the suction device is an aerosol. Alternatively, the substance produced by the suction device may be a gas.

The power supply unit 111 accumulates power. The power supply unit 111 supplies electric power to each component of the suction device 100 under the control of the control unit 116 . The power supply unit 111 may be composed of, for example, a rechargeable battery such as a lithium ion secondary battery.

The sensor unit 112 acquires various information regarding the suction device 100 . As an example, the sensor unit 112 is configured by a pressure sensor such as a microphone condenser, a flow rate sensor, a temperature sensor, or the like, and acquires a value associated with suction by the user. As another example, the sensor unit 112 is configured by an input device, such as a button or switch, that receives information input from the user.

The notification unit 113 notifies the user of information. The notification unit 113 is configured by, for example, a light emitting device that emits light, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates.

The storage unit 114 stores various information for operation of the suction device 100 . In particular, the storage unit 114 stores a heating profile that defines the time-series transition of the target temperature, which is the target value of the temperature of the heating unit. The storage unit 114 is configured by, for example, a non-volatile storage medium such as flash memory.

The communication unit 115 is a communication interface capable of performing communication conforming to any wired or wireless communication standard. Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like, for example, can be adopted as such a communication standard.

The heating unit 40 heats the aerosol source to atomize the aerosol source and generate an aerosol. As an example, the heating unit 40 is configured in a film shape and arranged so as to cover the outer periphery of the holding unit 60 . Then, when the heating part 40 generates heat, the base material part 151 of the stick-shaped base material 150 is heated from the outer periphery, and an aerosol is generated.

FIG. 6 shows a cross-sectional view of chamber 50 taken along line 5--5 shown in FIG. As shown in FIGS. 4 and 5 , the chamber 50 includes an opening 52 into which the stick-shaped substrate 150 is inserted, and a holder 60 that holds the stick-shaped substrate 150 . Chamber 50 is formed as a hollow member surrounding an interior space 80 that receives stick-shaped substrate 150 . The hollow member may be a tubular member with a bottom. In addition, the hollow member may be a cylindrical body without a bottom. The chamber 50 is preferably made of a metal with high thermal conductivity, such as stainless steel. This allows effective heating from the chamber 50 to the stick substrate 150 .

As shown in FIGS. 5 and 6 , the holding portion 60 includes a pressing portion 62 that presses a portion of the stick-shaped substrate 150 and a non-pressing portion 66 . The pressing portion 62 has an inner surface 62a and an outer surface 62b. The non-pressing portion 66 has an inner surface 66a and an outer surface 66b. As shown in FIG. 3 , the heating portion 40 is arranged on the outer surface 62 b of the pressing portion 62 . It is preferable that the heating part 40 is arranged on the outer surface 62b of the pressing part 62 without a gap.

The opening 52 of the chamber 50 is preferably capable of receiving the stick-shaped substrate 150 without compressing it. The shape of the opening 52 of the chamber 50 in the plane orthogonal to the longitudinal direction of the chamber 50, in other words, the direction in which the stick-type substrate 150 is inserted into the chamber 50 or the direction in which the side surface of the chamber 50 extends as a whole is polygonal or elliptical. It may be circular, but is preferably circular.

As shown in FIGS. 4 , 5 and 6 , the chamber 50 has two or more pressing portions 62 in the circumferential direction of the chamber 50 . As shown in FIGS. 5 and 6, the two pressing portions 62 of the holding portion 60 face each other. At least a partial distance between the inner surfaces 62 a of the two pressing parts 62 is preferably smaller than the width of the part of the stick-shaped substrate 150 inserted into the chamber 50 that is placed between the pressing parts 62 . As illustrated, the inner surface 62a of the pressing portion 62 is flat.

As shown in FIG. 6, the inner surface 62a of the pressing portion 62 has a pair of planar pressing surfaces facing each other, and the inner surface 66a of the non-pressing portion 66 connects both ends of the pair of planar pressing surfaces to form a pair of opposing planar pressing surfaces. curved non-pressing surface. As shown, the curved non-pressing surface may have a generally arcuate cross-section in a plane perpendicular to the longitudinal direction of chamber 50 . As shown in FIG. 6, the holding portion 60 is configured by a metal tubular body having a uniform thickness.

FIG. 7 is a vertical cross-sectional view of the chamber 50 including the non-pressing portion 66 with the stick-shaped substrate 150 held by the holding portion 60. FIG. FIG. 8 is a vertical cross-sectional view of the chamber 50 including the pressing portion 62 with the stick-shaped substrate 150 held by the holding portion 60. FIG. FIG. 9 is a cross-sectional view of chamber 50 taken along line 7-7 shown in FIG. Note that FIG. 9 shows a cross section of the stick-shaped base material 150 before being pressed so that it is easy to understand that the stick-shaped base material 150 is pressed by the pressing part 62 .

The gap 67 between the inner surface 66a of the non-pressing portion 66 and the stick-shaped substrate 150 shown in FIG. Even if it is pressed by and deformed, it is substantially maintained. This gap 67 can communicate with the opening 52 of the chamber 50 and the end surface of the stick-shaped substrate 150 positioned in the chamber 50 (the end surface on the lower side in FIGS. 7 and 8, that is, the end surface of the substrate portion 151). . This gap 67 is formed between the opening 52 of the chamber 50 and the end face of the stick-shaped substrate 150 positioned in the chamber 50 and positioned farther from the opening 52 of the chamber 50 (the lower end face in FIGS. 7 and 8, that is, It can also be said that it communicates with the end face of the base material portion 151 . Then, from the opening 52 of the chamber 50 to the end face of the stick-shaped base material 150 positioned outside the chamber 50 (the upper end face in FIGS. 7 and 8, that is, the end face of the mouthpiece 152), the gap 67 and the stick-shaped base material 150 An air flow path is formed through the interior of the As a result, there is no need to separately provide a flow path for introducing the air to be supplied to the stick-shaped substrate 150 in the suction device 100, so the structure of the suction device 100 can be simplified. In addition, since the portion of the non-pressing portion 66 that forms part of the gap 67 is exposed, the flow path can be easily cleaned. Furthermore, since the air is heated in the process of passing through the air gap 67, the heat radiation by the heating unit 40 is effectively used to increase the heating efficiency, and the stick-type base material 150 is excessively heated by the air flowing in with the puff. Temperature drop can be prevented. As a result, the power consumption of the heating unit 40 can be suppressed, and the reduction in flavor caused by the temperature drop of the stick-shaped base material 150 accompanying the puff can be prevented. From the viewpoint of ventilation resistance, etc., the height of the gap 67 between the inner surface 66a of the non-pressing portion 66 and the stick-shaped base material 150 is preferably 0.1 mm or more and 1.0 mm or less, and 0.2 mm or more and 0.2 mm or more. It is more preferably 0.8 mm or less, and most preferably 0.3 mm or more and 0.5 mm or less.

As shown in FIG. 9, when the stick-shaped substrate 150 is held by the holding portion 60, the distance LA between the inner surface 62a of the pressing portion 62 and the center of the stick _- shaped substrate 150 is equal to the inner surface of the non-pressing portion 66. It is shorter than the distance LB between 66a and the center of the stick _- shaped substrate 150. With such a configuration, the distance between the heating portion 40 arranged on the outer surface 62b of the pressing portion 62 and the center of the stick-shaped substrate 150 can be shortened compared to the case where the pressing portion 62 is not provided. Therefore, the heating efficiency of the stick-type substrate 150 can be enhanced.

As shown in FIGS. 4-8, chamber 50 has a bottom 56 . As shown in FIG. 8, the bottom part 56 supports a portion of the stick-shaped substrate 150 inserted into the chamber 50 by the bottom wall 56a so that at least a portion of the end face of the stick-shaped substrate 150 is exposed. . Also, the bottom portion 56 can support a portion of the stick-shaped base material 150 by the bottom wall 56 a so that the exposed end face of the stick-shaped base material 150 communicates with the gap 67 .

As shown in FIGS. 5, 7 and 8, the bottom 56 of the chamber 50 has a bottom wall 56a and may additionally have side walls 56b. The width of bottom 56 defined by sidewalls 56b may decrease toward bottom wall 56a. As shown in FIGS. 6 and 9 , the inner surface 66 a of the non-pressing portion 66 of the holding portion 60 is curved in the plane orthogonal to the longitudinal direction of the chamber 50 .

The shape of the inner surface 66a of the non-pressing portion 66 in the plane orthogonal to the longitudinal direction of the chamber 50 is the same as the shape of the opening 52 in the plane orthogonal to the longitudinal direction of the chamber 50 at any position in the longitudinal direction of the chamber 50. is preferred. In other words, the inner surface 66a of the non-pressing portion 66 is preferably formed by extending the inner surface of the chamber 50 forming the opening 52 in the longitudinal direction.

In this embodiment, as shown in FIGS. 6 and 8, the holding section 60 is provided with a state detection section 69 for detecting the state of the stick-shaped base material 150 held. Specifically, the state detection part 69 is arranged on at least one surface of the pair of planar pressing surfaces on the inner surface 62 a of the pressing part 62 so as to be aligned with the film member 156 (described later) of the stick-shaped substrate 150 . In the examples shown in FIGS. 6 and 8 , the state detection section 69 is arranged substantially at the center of the suction device 100 in the longitudinal direction and the lateral direction. For example, the state detection unit 69 is preferably configured with a pressure sensor to measure the contact pressure of the stick-shaped substrate 150 . In addition to the flat pressing surface, the state detection part 69 is positioned to contact a portion of the held stick-shaped base material 150 and is aligned with the film member 156 of the stick-shaped base material 150. can be placed at any position as long as For example, it may be located on the bottom 56 that supports a portion of the stick-shaped substrate 150 .

As shown in FIGS. 3-5, chamber 50 preferably has a cylindrical non-retaining portion 54 between opening 52 and retaining portion 60 . A gap may be formed between the non-holding portion 54 and the stick-shaped substrate 150 while the stick-shaped substrate 150 is held by the holding portion 60 .

As shown in FIGS. 5 to 9, the outer peripheral surface of the holding portion 60 has the same shape and size over the entire length of the holding portion 60 (the shape and size of the holding portion 60 on the plane orthogonal to the longitudinal direction of the holding portion 60). perimeter length).

4 and 5, the chamber 50 has a first guide portion 58 having a tapered surface 58a connecting the inner surface of the chamber 50 forming the opening 52 and the inner surface 62a of the pressing portion 62. is preferred.

As shown in FIG. 3, the heating section 40 has a heating element 42 . Heating element 42 may be, for example, a heating track. For example, as shown in FIG. 6, the outer surface 62b of the pressing portion 62 and the outer surface 66b of the non-pressing portion 66 are connected to each other at an angle, and the outer surface 62b of the pressing portion 62 and the outer surface 66b of the non-pressing portion 66 are connected to each other. A boundary 71 may be formed therebetween. The heating track preferably extends in a direction intersecting the extending direction of the boundary 71 (longitudinal direction of the chamber), preferably in a direction perpendicular to the extending direction of the boundary 71 .

As shown in FIG. 3, in addition to the heating element 42, the heating section 40 preferably has an electrically insulating member 44 covering at least one surface of the heating element 42. As shown in FIG. In this embodiment, the electrical insulation member 44 is arranged to cover both sides of the heating element. Also, the electrical insulating member 44 is preferably arranged within the region of the outer surface of the holding portion 60 . In other words, the electrical insulating member 44 is preferably arranged so as not to protrude from the outer surface of the holding portion 60 on the side of the first guide portion 58 in the longitudinal direction of the chamber 50 . As described above, since the first guide portion 58 is provided between the opening 52 and the pressing portion 62, in the longitudinal direction of the chamber 50, the shape of the outer surface of the chamber 50 and the shape of the chamber in the plane orthogonal to the longitudinal direction of the chamber The perimeter length can vary. Therefore, the electric insulating member 44 is arranged on the outer surface of the holding portion 60, thereby suppressing the occurrence of slack.

The heating portion 40 has at least one surface selected from the outer surface of the chamber 50 between the opening 52 and the first guide portion 58, that is, the outer surface of the non-holding portion 54, the outer surface of the first guide portion 58, and the outer surface of the non-pressing portion 66. It is preferable not to place one The heating part 40 is preferably arranged over the entire outer surface 62 b of the pressing part 62 .

As shown in FIG. 3 , the suction device 100 has strip-shaped electrodes 48 extending from the heating section 40 . The strip-shaped electrode 48 preferably extends from the planar outer surface 62b of the pressing portion 62 to the outside of the outer surface 62b of the pressing portion 62 when the heating portion 40 is arranged on the outer surface 62b of the pressing portion 62 .

3, 7 and 8, the heating unit 40 has a first portion 40a located on the opposite side of the opening 52 and a second portion 40b located on the opening 52 side. The heater power density of the second portion 40b is preferably higher than the heater power density of the first portion 40a. Alternatively, the temperature rise rate of the second portion 40b is preferably higher than the temperature rise rate of the first portion 40a. Alternatively, the heating temperature of the second portion 40b is preferably higher than the heating temperature of the first portion 40a at the same arbitrary time. The second portion 40b is a holding portion corresponding to 1/2 or more of the smokable substance contained in the stick-shaped substrate 150 in the longitudinal direction when the stick-shaped substrate 150 is held by the holding portion 60. Preferably, the outer surface of 60 is covered.

In the embodiment described above, the chamber 50 has a pair of pressing portions 62 facing each other, but the shape of the chamber is not limited to this. For example, the chamber 50 may have one pressing portion 62 or may have three or more pressing portions 62 .

As described above, the suction device 100 holds and heats the stick-shaped substrate 150 while pressing it with the pressing portion 62 . With such a configuration, various effects described below are achieved.

First, the thermal conductivity from the heating part 40 to the stick-shaped substrate 150 is improved. That is, the heating efficiency of the stick-type substrate 150 can be improved. Since the heating efficiency of the stick-shaped base material 150 is improved, the temperature of the stick-shaped base material 150 can reach the target temperature quickly, so the time required for preheating, which will be described later, can be shortened. Furthermore, since the heating efficiency of the stick-shaped base material 150 is improved, the followability of the temperature of the stick-shaped base material 150 to the temperature change of the heating unit 40 can be improved. As a result, firstly, it is possible to more easily control the amount of aerosol generated. Secondly, even if the temperature of the stick-type base material 150 drops as a result of puffing by the user, the original temperature can be immediately restored. Third, it is possible to reduce the influence of the external environment such as outside temperature. Fourthly, it becomes easy to realize the same temperature change in the stick-type substrate 150 as the temperature change in the heating profile described later. Fifth, it is possible to quickly produce the effect of improving the flavor, which is the effect of the reheating section described later in the heating profile.

Further, the suction device 100 presses the stick-shaped substrate 150 and heats it from the outer periphery. With such a configuration, regardless of the shape of the aerosol source in the stick-shaped base material 150, it is possible to improve the heating efficiency of the stick-shaped base material 150 and improve the temperature followability of the stick-shaped base material 150 described above. can be done. Furthermore, with such a configuration, the above-described heating efficiency of the stick-shaped base material 150 is improved regardless of errors in the shape or size of the stick-shaped base material 150 caused by variations occurring in the manufacturing process of the stick-shaped base material 150. , and improved temperature followability of the stick-type substrate 150 can be realized. On the other hand, it is difficult to achieve these effects in the comparative example having a configuration in which a blade-shaped heating portion is inserted into the stick-shaped base material 150 to heat the stick-shaped base material 150 from the inside. This is because, in the comparative example, even if the stick-shaped substrate 150 is pressed from the outer periphery, it is difficult to successfully bring the blade-shaped heating portion and the aerosol source in the stick-shaped substrate 150 into contact with each other.

Further, in the suction device 100, the heat insulation section 70 is arranged so as to surround the heating section 40 from the outer periphery. In that case, the outer surface 62b of the pressing portion 62 is located closer to the center of the internal space 80 than the outer surface 66b of the non-pressing portion 66, so that the outer surface 62b of the pressing portion 62 and the inner surface of the heat insulating portion 70 The thickness of the formed air layer can be increased. Alternatively, the thickness of the heat insulating portion 70 superimposed on the pressing portion 62 can be increased. Therefore, the heat insulating effect of the heat insulating portion 70 can be improved.

<<2. Structure of stick-type substrate >>
FIG. 10 is a schematic diagram schematically showing a configuration example of the stick-shaped substrate 150 heated by the suction device 100. As shown in FIG. A stick-type base material 150 shown in FIG. 10 includes a base material portion 151, a mouthpiece portion 152, and tip paper 153 around which these are wound. An example of the stick-shaped substrate 150 is a stick-shaped non-combustion heated cigarette.

The base member 151 includes an aerosol source 154 that generates an aerosol by atomization, a wrapping paper 155 for wrapping the aerosol source 154, and a film member 156 arranged between the aerosol source 154 and the wrapping paper 155. .

Aerosol source 154 is, for example, polyhydric alcohols such as glycerin and propylene glycol, and liquids such as water. If the inhalation device 100 is for non-combustion heated tobacco, the aerosol source 154 may include tobacco-derived or non-tobacco-derived flavoring components. Alternatively, if the inhalation device 100 is a medical inhaler, such as a nebulizer, the aerosol source may include a medicament. Note that the aerosol source 154 is not limited to liquid, and may be solid.

Wrapping paper 155 may be of any form commonly known to those skilled in the art, such as, for example, pulp-based. As for pulp, in addition to wood pulp such as softwood pulp and hardwood pulp, non-wood pulp such as flax pulp, hemp pulp, sisal pulp, and esparto, which are generally used for cigarette paper, are mixed. and obtained by manufacturing.

The film member 156 is a film-like member that is arranged between the aerosol source 154 and the wrapping paper 155, is overlapped with the wrapping paper 155 inside the wrapping paper 155, and is configured to wrap the aerosol source 154 together with the wrapping paper 155. be. The film member 156 may be overlaid on the entire area of the wrapping paper 155 or may be partially overlaid on a partial area.

The film member 156 is a state-changing member whose state is changed by an external action. In one example, the film member 156 is configured using a resin material whose hardness changes with heating. Specifically, the film member 156 is preferably constructed using a thermosetting resin material or a plastic resin material. Here, the thermosetting resin is a reactive mixture whose main component is a prepolymer (polycondensation intermediate product) with functional groups, and when heated, it cures by causing a cross-linking reaction that gradually forms a three-dimensional network structure. have the property Thermoplastic resins have the property of softening and flowing when heated to exhibit plasticity. The plasticity is a property of a material that receives a force and freely deforms beyond its elastic limit and retains its shape even after the force is removed.

Known materials may be used for both the thermosetting resin material and the plastic resin material. Examples of thermosetting resins may include phenolic resins, epoxy resins, melamine resins, urea resins, unsaturated polyester resins, alkyd resins, polyurethanes, thermosetting polyimides, and the like. Examples of thermoplastic resins may include polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, Teflon (registered trademark), ABS resin, AS resin, acrylic resin, and the like.

The mouthpiece 152 includes a cooling segment 157 and a filter segment 158 containing filter media. The cooling segment 157 is sandwiched adjacent to the base material portion 151 and the filter segment 158 in the axial direction of the stick-shaped base material 150, and the cooling segment 157 is provided with an opening V concentrically in the circumferential direction. may be The filter segment 158 includes a filter medium to which a predetermined amount of activated carbon is added.

The opening V provided in the cooling segment 157 is a hole for facilitating the inflow of air from the outside normally sucked by the user. can be lowered. The aperture V is preferably provided in a region at a predetermined distance (for example, 4 mm) or more in the direction of the cooling segment 157 from the boundary between the cooling segment 157 and the filter segment 158 . With such a configuration, it is possible to improve the cooling ability to lower the temperature of the components and air generated by heating, and further suppress the retention of the components and air in the cooling segment 157, resulting in can improve the delivery amount of

The tipping paper 153 may be of any form commonly known to those skilled in the art, such as, for example, pulp-based. As for pulp, in addition to being made from wood pulp such as softwood pulp and hardwood pulp, non-wood pulp such as flax pulp, hemp pulp, sisal pulp, and esparto, which are generally used for cigarette paper, are mixed. and obtained by manufacturing. These pulps may be used alone or in combination of multiple types at any ratio. Also, the tipping paper 153 may be composed of one sheet, or may be composed of a plurality of sheets or more.

<<3. Heating profile>>
The suction device 100 controls the operation (that is, heating operation) of the heating section 40 based on the heating profile. Specifically, the suction device 100 controls the temperature of the heating unit 40 by controlling the power supply operation from the power supply unit 111 to the heating unit 40 so that the target temperature specified in the heating profile changes in time series. do. The heating profile is information that defines the time-series transition of the target temperature, which is the target value of the temperature of the heating unit 40 . Information on the heating profile is stored in the storage unit 114 . The information is referred to when the heating unit 40 performs the heating operation to heat the stick-shaped base material 150 . In addition, the information may not only be referred to, but may also be updated during heating of the stick-type base material 150 .

Thereby, aerosol is generated as planned by the heating profile according to the operation of the heating unit 40 according to the heating profile. The heating profile is typically designed to optimize the flavor experienced by the user when the user inhales the aerosol produced from the stick-shaped substrate 150 . Therefore, by controlling the operation of the heating unit 40 based on the heating profile, it is possible to optimize the flavor tasted by the user.

The control unit 116 controls the operation of the heating unit 40 based on the deviation between the target temperature specified in the heating profile and the actual temperature of the heating unit 40 (hereinafter also referred to as the actual temperature). More specifically, the control unit 116 sets the target temperature of the heating unit 40 corresponding to the elapsed time from the start of control of the power supply operation to the heating unit 40 based on the heating profile, and the actual temperature of the heating unit 40. Based on the divergence, the power supply operation to the heating unit 40 by the power supply unit 111 is controlled. The control unit 116 controls the temperature of the heating unit 40 so that the time-series transition of the actual temperature of the heating unit 40 becomes the same as the time-series transition of the target temperature of the heating unit 40 defined in the heating profile. Temperature control of the heating unit 40 can be realized by, for example, known feedback control. Specifically, the control unit 116 supplies power from the power supply unit 111 to the heating unit 40 in the form of pulses by pulse width modulation (PWM) or pulse frequency modulation (PFM). In that case, the control section 116 can control the temperature of the heating section 40 by adjusting the duty ratio of the power pulse.

In feedback control, the control unit 116 may control the electric power supplied from the power supply unit 111 to the heating unit 40, for example, the duty ratio described above, based on the difference between the actual temperature and the target temperature. Feedback control may be PID control (Proportional-Integral-Differential Controller), for example. Alternatively, control unit 116 may perform simple ON-OFF control. For example, the control unit 116 instructs the power supply unit 111 to perform the heating operation by the heating unit 40 until the actual temperature reaches the target temperature, and when the actual temperature reaches the target temperature, the heating unit 40 starts heating. The heating operation may be stopped and the heating operation by the heating unit 40 may be performed again when the actual temperature becomes lower than the target temperature.

The temperature of the heating unit 40 can be quantified by, for example, measuring or estimating the electrical resistance value of the heating resistor that constitutes the heating unit 40 . This is because the electrical resistance value of the heating resistor changes according to the temperature. The electrical resistance value of the heating resistor can be estimated, for example, by measuring the amount of voltage drop across the heating resistor. The amount of voltage drop across the heating resistor can be measured by a voltage sensor that measures the potential difference applied to the heating resistor. In another example, the temperature of heating section 40 can be measured by a temperature sensor installed near heating section 40 .

Heating based on the heating profile is started at the timing when it is detected that an operation instructing the start of heating has been performed. An example of an operation for instructing the start of heating is pressing a button provided on the suction device 100 . Another example of the operation for instructing the start of heating is a puff operation. Another example of the operation for instructing the start of heating is reception of a signal from another device such as a smart phone.

After the start of heating, the aerosol source contained in the substrate gradually decreases over time. Typically, the heating operation by the heating unit 40 is stopped at the timing when the aerosol source is assumed to be exhausted. An example of the timing at which the aerosol source is assumed to run out is the timing at which a predetermined period of time has elapsed after starting control of the operation of the heating unit 40 based on the heating profile. An example of when the aerosol source is assumed to be depleted is when a predetermined number of puffs are detected. An example of the timing at which the aerosol source is assumed to run out is the timing at which a button provided on the suction device 100 is pressed. Such a button is pressed, for example, when the user cannot feel the flavor sufficiently.

The period during which a sufficient amount of aerosol is assumed to be generated is also called a puffable period. On the other hand, the period from the start of heating to the start of the puffable period is also called a preheating period. Heating performed in the preheating period is also referred to as preheating. The user may be notified when the puffable period starts and ends. In that case, the user can perform puffing during the puffable period by referring to such notification.

The control unit 116 controls the operation of the heating unit 40 based on the holding state of the stick-shaped substrate 150 by the holding unit 60 . Specifically, the control unit 116 controls the heating unit 40 so that the stick-type substrate 150 is heated based on the heating profile while a part of the stick-type substrate 150 is pressed by the pressing unit 62 of the holding unit 60 . control behavior. That is, the control unit 116 controls the operation of the heating unit 40 based on the heating profile in a state in which part of the stick-shaped base material 150 is pressed by the pressing unit 62 of the holding unit 60, and The amount of power supplied to the heating unit 40 is adjusted according to the corresponding target temperature, and the heating of the stick-shaped substrate 150 by the heating unit 40 is controlled. At that time, the control unit 116 may further adjust the power supply amount according to the strength of the pressure applied by the pressure unit 62 . In addition, the control unit 116 controls the heating unit so that the stick-type substrate 150 is not heated based on the heating profile when a part of the stick-type substrate 150 is not pressed by the pressing unit 62 of the holding unit 60 . The operation of 40 may be controlled (for example, no power is supplied to heating unit 40). Considering that the heating efficiency of the stick-shaped base material 150 is improved by pressing, it is possible to control the operation of the heating unit 40 according to the degree of improvement in the heating efficiency of the stick-shaped base material 150 with this configuration. becomes possible. Therefore, it is possible to provide the user with a puff experience of sufficient quality.

A heating profile includes a plurality of consecutive time intervals along the time axis. Each of the plurality of time intervals is set in association with a target temperature at the end of the time interval. Then, the control unit 116 sets the target temperature, the actual temperature, and The operation of the heating unit 40 is controlled based on the deviation of . Specifically, the control unit 116 controls the operation of the heating unit 40 so that the set target temperature is reached by the end of each of the plurality of time intervals included in the heating profile. An example heating profile is shown in Table 1 below.

The heating profile shown in Table 1 consists of an initial heating section, an intermediate cooling section, and a reheating section, which are included in order. In the example shown in Table 1, the initial heating section is the section from the start of the heating profile to 35 seconds later. The midway temperature drop section is a section from the end of the initial temperature rise section to 10 seconds later. The re-heating section is a section from the end of the middle temperature-lowering section to 310 seconds later. Including these time intervals in the heating profile allows the user to have a satisfactory quality puff experience throughout the heating profile, as described below. That is, it is possible to improve the quality of the user's puff experience.

The initial heating interval is the first included time interval of the heating profile. The target temperature set in the initial temperature rising section is higher than the initial value. The initial value is the assumed temperature of the heating unit 40 before starting heating. An example initial value is an arbitrary temperature, such as 0°C. Another example of an initial value is temperature corresponding to air temperature.

The midway temperature drop section is a time section included in the middle of the heating profile. The target temperature set for the intermediate temperature drop section is lower than the target temperature set for the time section immediately before the intermediate temperature drop section. In the example shown in Table 1, the target temperature of 230° C. set in the intermediate temperature decrease interval is lower than the target temperature of 295° C. set in the initial temperature increase interval, which is the immediately previous time interval.

The reheat interval is the time interval included at the end of the heating profile. The target temperature set for the reheating interval is higher than the target temperature set for the time interval immediately before the reheating interval. In the example shown in Table 1, the target temperature of 260° C. set in the reheating interval is higher than the target temperature of 230° C. set in the middle cooling interval, which is the previous time interval.

Time series transition of the actual temperature of the heating unit 40 when the control unit 116 controls the operation of the heating unit 40 according to the heating profile shown in Table 1 will be described with reference to FIG. FIG. 11 is a graph showing an example of time-series transition of the actual temperature of the heating unit 40 operated based on the heating profile shown in Table 1. In FIG. The horizontal axis of this graph is time (seconds). The vertical axis of this graph is the temperature of the heating unit 40 . A line 21 in this graph indicates a time series change in the actual temperature of the heating unit 40 .

As shown in FIG. 11, the actual temperature of the heating unit 40 rises in the initial temperature rising section and reaches the target temperature of 295° C. at the end of the initial temperature rising section. When the actual temperature of the heating unit 40 reaches the target temperature set in the initial temperature rising section, it is assumed that the temperature of the stick-shaped substrate 150 reaches a temperature at which a sufficient amount of aerosol is generated. The initial heating section is set at the beginning of the heating profile. Therefore, the temperature of the heating unit 40 is increased from the initial temperature to 295° C., which is the target temperature set in the initial temperature increase period, at once in the initial temperature increase period. Note that the initial temperature is the actual temperature of the heating unit 40 at the start of heating based on the heating profile. With such a configuration, it is possible to finish preheating early.

The control unit 116 performs temperature control of the heating unit 40 so that the actual temperature reaches the target temperature set in the initial temperature increase period during the initial temperature increase period. That is, the control unit 116 controls the temperature of the heating unit 40 from the initial temperature toward 295°C. If the actual temperature reaches 295°C before 35 seconds have passed since the start of heating, the control unit 116 controls the temperature of the heating unit 40 to maintain 295°C.

As shown in FIG. 11, the actual temperature of the heating unit 40 drops in the middle temperature-lowering section and reaches the target temperature of 230° C. at the end of the middle temperature-lowering section. The midway temperature drop section is set after the initial temperature rise section. Therefore, the temperature of the heating unit 40 is once lowered from the set temperature of the initial temperature increase interval to the set temperature of the intermediate temperature decrease interval in the intermediate temperature decrease interval. If the heating unit 40 is maintained at a high temperature such as the target temperature in the initial temperature rising section, the aerosol source contained in the stick-shaped base material 150 is rapidly consumed, causing inconveniences such as the flavor tasted by the user becoming too strong. occur. In this regard, by providing the midway temperature drop section, it is possible to avoid such inconveniences and improve the quality of the user's puff experience.

The control unit 116 controls so as not to supply power to the heating unit 40 during the mid-temperature drop section. In other words, the control unit 116 stops the power supply to the heating unit 40 in the middle temperature-lowering section, and controls the heating unit 40 not to perform heating. With this configuration, the actual temperature of the heating unit 40 can be lowered most quickly. In addition, it is possible to reduce the power consumption of the suction device 100 as compared with the case where the heating unit 40 is supplied with power even during the temperature drop section.

As shown in FIG. 11, the actual temperature of the heating unit 40 rises during the reheating interval and reaches the target temperature of 260° C. at the end of the reheating interval. The reheating section is set next to the midway temperature decreasing section and at the end of the heating profile. Therefore, in the reheating section, the heating unit 40 is again heated from the set temperature of the intermediate temperature decrease section to the set temperature of the reheating section, and then stops heating. If the temperature of the heating unit 40 is continued to decrease after the initial temperature increase period, the temperature of the stick-shaped base material 150 also decreases, so the amount of aerosol generated decreases, and the flavor tasted by the user may deteriorate. In this regard, by providing a re-heating section after the middle temperature-lowering section, it is possible to prevent deterioration of the flavor that the user enjoys even in the second half of the heating profile.

The control unit 116 performs temperature control of the heating unit 40 so that the actual temperature reaches the target temperature set in the reheating interval in the reheating interval. That is, the control unit 116 controls the temperature of the heating unit 40 toward 260.degree. If the actual temperature reaches 260°C before 310 seconds elapse from the start of the reheating interval, the control unit 116 controls the temperature of the heating unit 40 to maintain 260°C.

When the absolute value of the amount of change in the target temperature per unit time is compared for each of the initial temperature increase section, the intermediate temperature decrease section, and the reheating section, the reheating section is the smallest, and the intermediate temperature decrease section is the second smallest, The initial temperature rising section may be the largest. The absolute value of the amount of change in the target temperature per unit time in the initial heating section is the value obtained by dividing the absolute value of the difference between the target temperature set in the initial heating section and the initial value by the time length of the initial heating section. is. The absolute value of the amount of change in the target temperature per unit time in the intermediate temperature drop section is the target temperature set in the intermediate temperature drop section and the target set in the time section immediately before the intermediate temperature drop section (for example, the initial temperature increase section). It is the value obtained by dividing the absolute value of the difference from the temperature by the time length of the intermediate temperature drop section. The absolute value of the amount of change in the target temperature per unit time in the reheating interval is set between the target temperature set in the reheating interval and the time interval one before the reheating interval (e.g., midway temperature drop interval). It is the value obtained by dividing the absolute value of the difference from the target temperature set by the time length of the reheating interval. In addition, when comparing the time lengths of the initial temperature increase interval, the intermediate temperature decrease interval, and the reheating interval, the intermediate temperature decrease interval is the shortest, the initial temperature increase interval is the second shortest, and the reheating interval is the longest. With such a configuration, as shown in FIG. 11, the heating unit 40 rapidly rises in temperature in the initial temperature increase section, quickly exits the high temperature state in the middle temperature decrease section, and slowly increases in temperature in the reheating section. becomes. Therefore, it is possible to finish the preheating early, and to provide the user with a puff experience of sufficient quality from the beginning to the end of the heating profile.

The control unit 116 may determine at least part of switching between the plurality of time intervals in the heating profile based on the actual temperature of the heating unit 40 . For example, the control unit 116 switches from the initial temperature increase interval to the intermediate temperature decrease interval and the end of the temperature re-increase interval when the deviation between the target temperature set for each time interval and the actual temperature of the heating unit 40 is predetermined. The determination may be made based on the fact that the threshold of .

The control unit 116 may determine at least part of the switching of the plurality of time intervals in the heating profile based on the elapsed time. For example, the control unit 116 may determine the end of the midway temperature drop section based on the elapsed time from the start of the midway temperature drop section. For example, in the heating profile shown in FIG. 11, the middle temperature drop section is set to 10 seconds. Therefore, the control unit 116 determines switching to the reheating interval and causes the heating unit 40 to resume heating when 10 seconds have passed since the start of the intermediate temperature lowering interval. With such a configuration, it is possible to determine whether to switch from the mid-temperature decrease section to the re-temperature increase section without measuring the temperature of the heating unit 40, so that the processing load on the control unit 116 can be reduced. Furthermore, even in the case of measuring the temperature of the heating unit 40 based on the electrical resistance value of the heating resistor constituting the heating unit 40, while stopping the power supply to the heating unit 40 during the temperature drop section, It becomes possible to determine whether to switch to the reheating section.

However, the actual temperature of the heating unit 40 at the end of the middle temperature-lowering section may fluctuate depending on the external environment such as the outside air temperature. For example, when operating based on the heating profile shown in FIG. 11, the actual temperature of the heating unit 40 at the end of the intermediate temperature drop section is 220° C. when the outside temperature is low, and 240° C. when the outside temperature is high. can be

Therefore, the control unit 116 controls the heating unit 40 based on the actual temperature of the heating unit 40 and the target temperature set in the intermediate temperature-lowering interval at the start of the time interval (that is, the re-heating interval) following the intermediate temperature-lowering interval. 40 operations. More specifically, control unit 116 performs heating at the first duty ratio when the actual temperature of heating unit 40 is lower than the target temperature set for the intermediate temperature-lowering interval at the beginning of the time interval following the intermediate temperature-lowering interval. Power is supplied to the unit 40 . On the other hand, when the actual temperature of heating unit 40 is equal to or higher than the target temperature set for the intermediate temperature-lowering interval at the start of the time interval following the intermediate temperature-lowering interval, control unit 116 controls heating unit 40 at the second duty ratio. supply power to Here, the first duty ratio is greater than the second duty ratio. Here, the duty ratio is a ratio of a period during which power supply to the heating unit 40 is continued in a predetermined period. According to such a configuration, even if there is a deviation between the target temperature and the actual temperature of the heating unit 40 due to the influence of the external environment, the deviation can be quickly reduced. It becomes possible to suppress deterioration.

FIG. 12 is a flowchart showing an example of the flow of processing executed by the suction device 100. As shown in FIG.

As shown in FIG. 12, first, the suction device 100 raises the temperature of the heating unit 40 from the initial temperature to the target temperature set in the initial temperature rising section (step S102).

Next, the suction device 100 stops power supply to the heating unit 40 in the middle temperature-lowering section, and lowers the temperature of the heating unit 40 to the target temperature set in the middle temperature-lowering section (step S104).

Next, the suction device 100 raises the temperature of the heating unit 40 to the target temperature set in the reheating interval in the reheating interval (step S106).

Then, the suction device 100 stops supplying power to the heating unit 40 when the re-heating section ends (step S108).

<<4. Suction system>>
(1) Configuration of Suction System The suction system according to this embodiment includes a suction device 100 that atomizes the aerosol source 154 described with reference to FIGS. 1 to 9 to generate aerosol, and the aerosol source 154 described with reference to FIG. and a stick-type substrate 150 . In the suction system according to the present embodiment, the suction device 100 receives the stick-type substrate 150 inside and controls the heating operation based on the heating profile described with reference to FIGS. 11 and 12, for example.

Here, the suction device 100 and the stick-type substrate 150 included in the suction system may be sold individually or as a set when distributed in the market. In the process, in place of the stick-type base material 150, non-genuine products such as compatible or counterfeit products made by a third party may be marketed separately and sold to users. A non-genuine product is often inferior in quality compared to the stick-type base material 150 that is a genuine product. Also, if non-genuine products are used with the suction device 100, an inferior flavor may be delivered to the user, resulting in an unsatisfactory suction experience for the user. Furthermore, since the suction device 100 is heated, the use of a non-genuine product for the suction device 100 may pose a safety problem.

According to the present embodiment, the suction device 100 and/or the suction system are provided that can appropriately detect the use of such non-genuine stick-type substrates and further limit the use thereof. Further, the present invention provides a suction device 100 and/or a suction system that can prompt a user to properly use the suction device when the use of a non-genuine stick-type base material 150 is properly detected.

As described with reference to FIGS. 6 and 8, the suction device 100 according to the present embodiment is provided with the state detection section 69 that detects the state of the stick-shaped substrate 150 held therein. Then, the state of the pressed stick-shaped base material 150 is detected by using the state detection unit 69 . The state of the stick-type substrate 150 is, for example, the state of contact based on the strength of pressure. In order to detect such a contact state, the state detection section 69 preferably measures the stress from the pressed stick-shaped base material 150 . Specifically, the state detection section 69 preferably measures the contact pressure of the held stick-shaped base material 150 by configuring the state detection section 69 with a pressure sensor. A contact sensor may be used instead of the pressure sensor.

Further, as described with reference to FIG. 10, the stick-type substrate 150 according to the present embodiment includes the substrate portion 151. In the substrate portion 151, the film member 156 is placed between the aerosol source 154 and the wrapping paper 155. placed. The film member 156 is a state-changing member whose state is changed by an external action, and is made of, for example, a resin material whose hardness is changed by heating. That is, the hardness of the film member 156 of the stick-shaped substrate 150 held by the suction device 100 changes as it is heated through the heating unit 40 .

Here, the hardness of the film member 156 of the stick-shaped base material 150 can be associated with the strength of pressure (that is, stress) detected by the state detection unit 69 while being held by the suction device 100 . Specifically, when the film member 156 is made of a thermosetting resin material that hardens when heated, the hardness increases as the film member 156 is heated through the heating section 40 of the suction device 100 . Along with this, the stress measured by the state detection unit 69 also increases. On the other hand, if the film member 156 is made of a thermoplastic resin material that softens when heated, the hardness of the film member 156 decreases as it is heated through the heating unit 40 . Along with this, the stress measured by the state detection unit 69 also decreases. In other words, the hardness of the film member 156 of the stick-shaped base material 150 can be specified by measuring the strength of pressure detected by the state detection section 69 of the suction device 100 .

That is, the hardness of the film member 156 is associated with the stress measured by the state detection unit 69, so that the suction device 100 can detect the state of the stick-shaped substrate 150 based on the magnitude of the stress. The state of the tick-type substrate 150 here may specifically include the state of the film member 156, which is a state-changing member. In the suction device 100 of the present embodiment, the state of the film member 156 of the stick-shaped substrate 150 satisfies a predetermined condition while the heating unit 40 is heating the stick-shaped substrate 150 and/or before the heating. It is configured to determine if it satisfies the The suction device 100 controls power supply to the heating unit 40 according to the determination result.

In this way, a mode of heating control based on the state of the film member 156 of the stick-type substrate 150 is provided. Note that the control mode here includes each operation of permission, prohibition, and suppression.

(2) Operation Examples of Suction System Some operation examples of the suction system according to the present embodiment will be described below. In each operation example, while the heating unit 40 is heating the stick-shaped substrate 150 and/or before the heating, the control unit 116 determines whether the state of the stick-shaped substrate 150 satisfies a predetermined condition. Then, the power supply to the heating unit 40 is controlled according to the result of the determination.

13 to 15 are for explaining the operation example 1, and FIGS. 16 to 18 are for explaining the operation example 2. FIG. 13 and 16 are block diagrams functionally showing the configuration of the control section 116 included in the suction device 100 regarding each operation example of the suction system. 14 and 17 are flowcharts showing the flow of processing in each of Operation Examples 1 and 2.

It should be noted that the block diagrams shown in FIGS. 13 and 16 are merely examples, and the present invention is not limited to these, and arbitrary other functional blocks may be included or some functional blocks may be omitted. In addition, each processing step shown in the flowcharts of FIGS. 14 and 17 is merely an example, and is not limited to this, and any other processing steps may be included, or some processing steps may be omitted. good too. Furthermore, the order of each processing step shown here is merely an example, and is not limited to this, and may be in any order, or may be executed in parallel in some cases.

(2-1) Operation example 1
As shown in the block diagram of FIG. 13, the control unit 1161 that executes the processing of the operation example ₁ includes a power supply instruction unit 116a, a detection instruction unit 116b, a determination unit 116c, and a notification instruction unit 116d. The power supply instruction unit 116a instructs the power supply unit 111 to supply power to the heating unit 40 or to stop supplying power. The detection instruction section 116 b instructs the state detection section 69 to detect the state of the stick-shaped base material 150 . The determination unit 116 c determines the state of the stick-shaped base material 150 . The notification instruction unit 116d instructs the notification unit 113 to perform a predetermined notification operation.

As shown in the flowchart of FIG. 14 , in Operation Example 1, the detection instructing unit 116b instructs the state detection unit 69 at an arbitrary timing after the operation of the suction device 100 is first started. real-time detection of the state of (step S202). In addition, the power supply instruction unit 116a instructs the power supply unit 111 to supply power to the heating unit 40 in response to an operation to instruct the start of heating, and the heating unit 40 performs a heating operation based on the heating profile. is started (step S204). As a result, the stick-shaped substrate 150 held by the holding portion 60 is heated.

Next, the determining unit 116c determines whether the state of the stick-shaped substrate 150 satisfies a predetermined condition while the heating unit 40 is heating the stick-shaped substrate 150 (Step S206). Specifically, the determination unit 116c determines whether the strength of pressure (that is, stress) by the stick-shaped substrate 150 detected by the state detection unit 69 is within a predetermined first range. Note that the determination may be performed while the heating unit 40 is heating the stick-shaped base material 150 and/or before the heating.

The power supply instruction unit 116a controls power supply to the heating unit 40 in response to the determination that the state of the stick-shaped base material 150 satisfies the predetermined condition in step S206. Specifically, when the strength of the pressure applied by the stick-shaped base material 150 is within the first range (step S206: Yes), the power supply instruction unit 116a may permit power supply to the heating unit 40 (step S208 ). In other words, it is determined that the state of the stick-type substrate 150 is normal. Subsequently, the power supply instruction unit 116a causes the heating unit 40 to continue the heating operation based on the heating profile, and causes the determination unit 116c to continue real-time determination processing (step S206).

Here, the first range defines that the stick-type substrate 150 is in a normal state. Specifically, the first range is set in advance so as to be associated with a permissible range of hardness of the stick-type substrate 150 when the stick-type substrate 150 is a genuine product and the usage method specified by the manufacturer is complied with. is set. That is, the first range is determined in advance by the manufacturer's design/experiment, with the upper and lower limits associated with the allowable range of hardness of the film member 156 , and stored in the storage unit 118 .

In this respect, the first range is set so that the strength of the pressure applied by the stick-shaped base material 150 is within that range when the stick-shaped base material 150 is not yet used (that is, in an unused state). good. Also, the first range is preferably set so that the strength of the pressure is outside the range when the stick-shaped base material 150 is not a genuine product or after use. Note that the stick-type base material 150 after use means, for example, that the stick-type base material 150 is in a used state after performing a predetermined number of puffing operations while the stick-type base material 150 is heated. may be

Returning to FIG. 14, if the strength of the pressure applied by the stick-shaped base material 150 is not within the first range (step S206: No), it is determined that the state of the stick-shaped base material 150 is not normal. In this case, the power supply instruction unit 116a preferably prohibits power supply to the heating unit 40 (step S210). The state of the stick-type base material 150 is not normal, for example, it is an abnormal situation such as non-genuine products being used, or even if genuine products are being used, they are repeatedly reused. can be considered. That is, in the middle of heating the stick-shaped base material 150 by the heating unit 40, if the pressure strength deviates from the first range and the desired transition does not occur, the stick-shaped base material 150 The state is determined to be abnormal, and power supply to the heating unit 40 is prohibited.

When power supply to the heating unit 40 is prohibited in step S210, the notification instructing unit 116d instructs the notification unit 113 to notify that effect. In response, the notification unit 113 executes a predetermined notification operation (step S212). The notification operation is performed using a light emitting device that emits light, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates. For example, it is preferable to indicate to the user that power supply is prohibited by causing the light emitting device to emit red light.

After step S212, the series of processes of operation example 1 ends. Note that the heating operation by the heating unit 40 is stopped as a result of the series of processes.

FIG. 15 shows a graph of the time-series transition of the actual temperature of the heating unit 40 when the series of processes of Operation Example 1 are executed. The horizontal axis of this graph is time (seconds). The vertical axis of this graph is the temperature (° C.) of the heating unit 40 . A line 21a in this graph indicates a time-series change in the actual temperature of the heating unit 40 .

In the example of the graph shown in FIG. 15, at time T1 in the middle of the reheating section, it is determined that the strength of the pressure applied by the stick-shaped substrate 150 is outside the first range. Power supply to 40 is prohibited. After time T1, power supply to the heating unit 40 is stopped regardless of the target temperature set in the heating profile. As a result, unlike line 21 in the graph of FIG. 11, the temperature of heating unit 40 decreases from time T1 on line a in the graph. That is, the section after the time T1 in the time section that was initially the temperature reheating section is forcibly set as the heating prohibited section.

In the example of the graph in FIG. 15 , regarding Operation Example 1, it is assumed that the strength of pressing by the stick-shaped base material 150 is out of the first range in the middle of the reheating section defined in the heating profile. However, it is not limited to this. For example, in the middle of the initial temperature increase section or the middle temperature decrease section specified in the heating profile, even if the pressing force deviates from the first range, the heating is performed accordingly. Power supply to the unit 40 may be prohibited.

Note that the first range may be flexibly set by the manufacturer other than the above. Specifically, the first range may be set so as to be associated with the heating profile and change over time. In one example, the first range may be associated with the heating time by the heating unit 40 and set to change over time by changing the upper limit and/or the lower limit according to the heating time. The heating time is preferably measured by a built-in timer (not shown) provided in the processor. In another example, the first range is associated with the target temperature for each time interval of the heating profile, and the upper limit and/or the lower limit may be set to change over time according to the target temperature during the time interval. good.

Thus, according to the suction system of the present embodiment, by flexibly setting the first range in the suction device 100, it is possible to appropriately detect the use and state of the stick-type base material 150, use may be restricted. Inappropriate use of stick-shaped base material 150 includes use of non-genuine products (including compatible products or counterfeit products) that are assumed not to provide the desired sucking experience, excessive use of authorized stick-shaped base material 150 including the reuse of Also, when such inappropriate use is detected, by notifying the user to that effect, it is possible to prompt the user to stop the inappropriate use. As a result, it is possible to prevent the inconvenience of delivering inferior aerosol to the user, and encourage the user to use the suction device 100 safely. In this way, the suction experience using the suction device 100 can be kept from deteriorating.

(2-2) Modification of Operation Example 1 In the operation example 1 described above, first, the detection instruction unit 116b causes the state detection unit 69 to start real-time detection of the state of the stick-type base material 150 (step S202), next, the power supply instruction unit 116a instructs the power supply unit 111 to supply power to the heating unit 40 in response to the operation to instruct the start of heating, and the heating unit 40 performs heating based on the heating profile. It is assumed that the operation is started (step S204). Instead, in the modified example, between steps S202 and S204, determination unit 116c determines that the strength of pressure (that is, stress) by stick-shaped base material 150 detected by state detection unit 69 is a predetermined number. A determination may be made as to whether it is within a range. Then, when the stress is within the predetermined first range, the process may proceed to step S204 for the first time, and the heating unit 40 may start the heating operation based on the heating profile.

On the other hand, when the stress is not within the predetermined first range, the power supply instructing section 116 a preferably prohibits the power supply section 111 from supplying power to the heating section 40 . This is based on the assumption that the stick-shaped substrate 150 should be presumed to be in a bad state if, in the initial state, the stress is not within the predetermined first range. The defective state includes, for example, a state in which an inappropriate stick-shaped base material 150 such as a defective product or a counterfeit product is used, and a state in which the holding part 60 cannot properly hold the stick-shaped base material 150. included.

Thus, in the modified example, the process of determining whether the stress is within the predetermined first range is performed while the heating unit 40 is performing the heating operation based on the heating profile and before the start of the heating operation. in both As a result, the state of the stick-type base material 150 can be further appropriately detected, and its use can be prohibited when it is in a defective state.

(2-3) Operation example 2
In the operation example 1 described above, when the used stick-shaped base material 150 is reused, the suction device 100 forcibly prohibits the heating of the stick-shaped base material 150 . On the other hand, in Operation Example 2, even if the stick-shaped base material 150 is reused, if certain conditions are satisfied, the heating of the stick-shaped base material 150 is not prohibited, and the heating is allowed. configured to suppress.

As shown in the block diagram of FIG. 16, the control unit 1162 that executes the processing of the operation example ₁ includes a power supply instruction unit 116g, a detection instruction unit 116h, a determination unit 116i, a correction unit 116j, and a notification instruction unit 116k. Of these, the power supply instruction unit 116g, the detection instruction unit 116h, the determination unit 116i, and the notification instruction unit _116k correspond to the power supply instruction unit 116a, the detection instruction unit 116b, the determination unit 116c, and the notification instruction unit 116a of the control unit 1161 shown in FIG. It is the same as the instruction part 116d. In Operation Example 2, the correction unit 116j corrects the target temperature defined in the heating profile.

As shown in the flowchart of FIG. 17, in the operation example 2, steps S302 to S308 are the same as steps S202 to S208 of the operation example 1 shown in FIG. Specifically, in Operation Example 2, at an arbitrary timing after the operation of the suction device 100 is first started, the detection instruction section 116h instructs the state detection section 69 to detect the state of the stick-shaped substrate 150 in real time. is started (step S302). In addition, the power supply instruction unit 116g instructs the power supply unit 111 to supply power to the heating unit 40 in response to an operation to instruct the start of heating, and the heating unit 40 performs a heating operation based on the heating profile. is started (step S304). Next, while the heating unit 40 is heating the stick-shaped base material 150, the determination unit 116i determines whether the strength of pressure (that is, stress) by the stick-shaped base material 150 is within the first range ( step S306). Then, when it is determined that the pressing force is within the first range (Yes), the power supply instruction unit 116g permits power supply to the heating unit 40 (step S308).

In addition, in Operation Example 2, when it is determined in step S306 that the strength of pressure by the stick-shaped base material 150 is not within the first range (No), the determination unit 116i further sets the strength of pressure to the second range. It is determined whether it is within the range (step S322). Then, depending on whether or not the strength of the pressing by the stick-shaped base material 150 is not within the first range but is determined to be within the second range, the power supply instructing unit 116g instructs the power supply to the heating unit 40. are controlled differently.

Specifically, when it is determined in step S322 that the strength of the pressing force by the stick-shaped base material 150 is within the second range (Yes), the power supply instruction unit 116g prohibits (prohibits) power supply to the heating unit 40. (step S324). Specifically, the correction unit 116j corrects at least part of the target temperature specified in the heating profile, and causes the heating unit 40 to perform the heating operation based on the corrected heating profile.

Specifically, the correction unit 116j updates at least part of the target temperature to a value lower than the specified target value so as to weaken the degree of heating. This is because, as long as the user is using a genuine product, there is no need to intentionally prohibit power supply as in Operation Example 1. Instead, the stick-type base material 150 can be heated by limiting it to a low temperature. Based on policy. This allows the user to reuse the regular stick-type base material 150, and clearly indicates that the stick-type base material 150 is in a reused state by making the sucking experience worse than that of the first use. That is, it is possible to prompt the user to replace the stick-type substrate 150 .

Alternatively, the correction unit 116j may update at least part of the target temperature to a value higher than the specified target value so as to increase the degree of heating. As long as the user is using a genuine product, the power supply is not prohibited as in the operation example 1. Instead, the stick-type base material 150 is heated to a high temperature. It is based on the policy that it is better to deliver the same flavor to the user as the first time. As a result, it is possible to allow the user to reuse the regular stick-type base material 150 and to provide the user with the same sucking experience as the first time.

Here, the second range defines that the stick-type substrate 150 is in an acceptable reuse state. Specifically, in the second range, the hardness of the stick-shaped base material 150 can be obtained when the stick-shaped base material 150 is in a state where it is still acceptable even if the regular product is reused. Preconfigured to be associated with tolerances. That is, the second range is determined in advance by the manufacturer's design/experiment, with the upper and lower limits associated with the allowable range of hardness of the film member 156 after use, and stored in the storage unit 118. . Note that "after use" refers to a state after the stick-type base material 150 has been heated and the user has performed a predetermined number of puffing operations from an unused state. Note that the second range may be flexibly set by the manufacturer, similar to the first range.

Returning to FIG. 17, when power supply to the heating unit 40 is suppressed in step S324, the notification instructing unit 116k instructs the notification unit 113 to notify that effect. In response, the notification unit 113 executes a predetermined notification operation (step S326). The notifying operation of heating suppression is preferably different from the notifying operation of heating prohibition in step S212 of operation example 1 and step 344 of operation example 2 (described later). As a result, the user can be notified that the current use of the stick-type base material 150 is reuse, and can be prompted to stop such puffing and replace the stick-type base material 150 .

If the strength of the pressure applied by the stick-shaped base material 150 is not within the second range in step S322 (No), the subsequent steps S342 and S344 are operation example 1 related to prohibiting and notifying the power supply to the heating unit 40. are the same as steps S210 and S212. That is, the power supply instruction unit 116g prohibits power supply to the heating unit 40 (step S342), and then the notification instruction unit 116k instructs the notification unit 113 to notify the heating prohibition (step S344).

After step S344, the series of processes of operation example 1 ends. Note that the heating operation by the heating unit 40 is stopped as a result of the series of processes.

FIG. 18 shows a graph of the time-series transition of the actual temperature of the heating unit 40 when the series of processes of Operation Example 2 are executed. The horizontal axis of this graph is time (seconds). The vertical axis of this graph is the temperature (° C.) of the heating unit 40 . A line 21a in this graph indicates a time-series change in the actual temperature of the heating unit 40 .

Table 2 shows the heating profile applied in FIG. Here, the heating profile is adjusted at time T2 included in the reheating section among the initial temperature increasing section, the intermediate temperature decreasing section, and the reheating section. Table 2 shows the heating profile after adjustment.

As shown in Table 2, the reheating section included in the heating profile was initially defined to raise the target temperature of the heating unit 40 from 230°C to 260°C. That is, the initial segment target temperature of the reheating segment was associated with the final stage of the reheating segment and was set to 260° C., which is the target temperature. The current time is time T2.

As shown in FIG. 18, in the reheating interval corresponding to time T2, the initial interval of the heating profile was determined in response to the determination that the strength of the pressure applied by the stick-shaped substrate 150 was not within the second range. The target temperature of 260°C is updated to 250°C after adjustment. As a result, in the reheating section, the heating operation of the heating unit 40 is suppressed at a lower temperature than initially planned.

As a result of the adjustment of the heating profile, the line 21b of the heating profile graph becomes different from the original line 21 in the middle of the reheating interval. Specifically, as shown in the figure, the slope of the straight line after time T2 in the reheating section is smaller than the slope of the straight line before time T2. In operation example 2, the section target temperature is lowered from 260° C. to 250° C. by 10° C., but the value of the temperature to be lowered may be a predetermined value or according to a predetermined formula. , may be dynamically calculated based on the stress values.

In the example of the graph in FIG. 15, regarding Operation Example 2, the strength of the pressure by the stick-shaped base material 150 is outside the second range in the middle of the reheating section defined in the heating profile. However, it is not limited to this. The power supply to the heating unit 40 may be suppressed by updating the target temperature in the temperature rising section with a lower value.

As described above, according to the suction system of the present embodiment, by flexibly setting the second range in the suction device 100, it is possible to appropriately detect reuse of the regular stick-shaped base material 150 by the user, and furthermore, Inappropriate use may be restricted. Inappropriate use of stick-shaped base material 150 includes use of non-genuine products (including compatible products or counterfeit products) that are assumed not to provide the desired sucking experience, excessive use of authorized stick-shaped base material 150 including the reuse of In addition, when such reuse is detected, the user can be notified to that effect to prompt the user to stop reuse. As a result, it is possible to prevent the inconvenience of delivering inferior aerosol to the user, and encourage the user to use the suction device 100 safely. In this way, the suction experience using the suction device 100 can be kept from deteriorating.
