[0029] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.

[0030] <1. Example of suction device configuration> The inhalation device is a device that generates a substance to be inhaled by a user. In the following description, the substance generated by the inhalation device is described as an aerosol. Alternatively, the substance generated by the inhalation device may be a gas.

[0031] Fig. 1 is a schematic diagram showing a configuration example of a suction device. As shown in Fig. 1, a suction device 100 according to this configuration example includes a power supply unit 111, a sensor unit 112, a notification unit 113, a storage unit 114, a communication unit 115, a control unit 116, a heating unit 121, a storage unit 140, and a heat insulating unit 144.

[0032] The power supply unit 111 accumulates power. Then, the power supply unit 111 supplies power to each component of the suction device 100 based on the control of the control unit 116. The power supply unit 111 can be configured by, for example, a rechargeable battery such as a lithium ion secondary battery.

[0033] The sensor unit 112 acquires various information related to the suction device 100. As one example, the sensor unit 112 is configured with a pressure sensor such as a condenser microphone, a flow rate sensor, a temperature sensor, or the like, and acquires values ​​associated with suction by the user. As another example, the sensor unit 112 is configured with an input device that accepts information input from the user, such as a button or a switch.

[0034] The notification unit 113 notifies the user of information. The notification unit 113 is configured, for example, by 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.

[0035] The storage unit 114 stores various types of information for the operation of the suction device 100. The storage unit 114 is configured by, for example, a non-volatile storage medium such as a flash memory.

[0036] The communication unit 115 is a communication interface capable of performing communication in compliance with any wired or wireless communication standard, such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).

[0037] The control unit 116 functions as an arithmetic processing unit and a control unit, and controls the overall operation within the suction device 100 in accordance with various programs. The control unit 116 is realized by electronic circuits such as a CPU (Central Processing Unit) and a microprocessor.

[0038] The storage section 140 has an internal space 141, and holds the stick-shaped substrate 150 while storing a part of the stick-shaped substrate 150 in the internal space 141. The storage section 140 has an opening 142 that communicates the internal space 141 with the outside, and holds the stick-shaped substrate 150 inserted into the internal space 141 from the opening 142. For example, the storage section 140 is a cylindrical body with the opening 142 and the bottom 143 as the bottom surface, and defines a columnar internal space 141. The storage section 140 also has the function of defining a flow path for air to be supplied to the stick-shaped substrate 150. An air inlet hole that is an entrance of air to such a flow path is arranged in the bottom 143, for example. On the other hand, an air outlet hole that is an exit of air from such a flow path is the opening 142.

[0039] The stick-type substrate 150 includes a substrate portion 151 and a suction mouth portion 152. The substrate portion 151 includes an aerosol source. In this configuration example, the aerosol source is not limited to a liquid, and may be a solid. When the stick-type substrate 150 is held in the storage portion 140, at least a part of the substrate portion 151 is stored in the internal space 141, and at least a part of the suction mouth portion 152 protrudes from the opening 142. When the user holds the suction mouth portion 152 protruding from the opening 142 in his / her mouth and inhales, air flows into the internal space 141 from an air inlet hole (not shown) and reaches the user's mouth together with the aerosol generated from the substrate portion 151.

[0040] The heating unit 121 generates aerosol by heating the aerosol source and atomizing the aerosol source. In the example shown in FIG. 1, the heating unit 121 is configured in a film shape and arranged to cover the outer periphery of the storage unit 140. When the heating unit 121 generates heat, the substrate unit 151 of the stick-shaped substrate 150 is heated from the outer periphery, and an aerosol is generated. The heating unit 121 generates heat when power is supplied from the power supply unit 111. As an example, power may be supplied when the sensor unit 112 detects that the user has started inhaling and / or that predetermined information has been input. When the sensor unit 112 detects that the user has stopped inhaling and / or that predetermined information has been input, power supply may be stopped.

[0041] The heat insulating section 144 prevents heat transfer from the heating section 121 to other components. For example, the heat insulating section 144 is made of a vacuum heat insulating material, an aerogel heat insulating material, or the like.

[0042] The above describes an example of the configuration of the suction device 100. Of course, the configuration of the suction device 100 is not limited to the above, and various configurations such as those exemplified below may be used.

[0043] As an example, the accommodation unit 140 may include an opening / closing mechanism such as a hinge that opens and closes a part of the outer shell that forms the internal space 141. The accommodation unit 140 may then open and close the outer shell to clamp the stick-shaped substrate 150 inserted into the internal space 141. In this case, the heating unit 121 may be provided at the clamping location in the accommodation unit 140, and may heat the stick-shaped substrate 150 while pressing it.

[0044] Here, the power supply unit 111 is an example of a power supply unit that supplies power to the heating unit 121. The stick-shaped substrate 150 is an example of an aerosol product that contains an aerosol source.

[0045] The inhalation device 100 and the stick-type substrate 150 work together to generate an aerosol that is inhaled by a user, and therefore the combination of the inhalation device 100 and the stick-type substrate 150 may be considered as an aerosol generating system.

[0046] <2. Detailed configuration of the heating section> Fig. 2 is a planar development view of heating unit 121 according to this embodiment. Fig. 3 is a view showing the arrangement of heating unit 121 according to this embodiment. Fig. 4 is a cross-sectional view of a portion of suction device 100 according to this embodiment where heating unit 121 is arranged.

[0047] As shown in Fig. 2, the heating section 121 has an electrical resistance section 10 and an electrical insulation section 20. In Fig. 2, the dimensions of the electrical resistance section 10 and the electrical insulation section 20 are shown, and the unit is millimeters (mm).

[0048] 3, the heating unit 121 is disposed around the storage unit 140. The storage unit 140 is made of a material having a predetermined heat conductivity, such as SUS (Steel Use Stainless). Therefore, the heat generated by the heating unit 121 can heat the stick-shaped substrate 150 stored in the internal space 141 of the storage unit 140 via the storage unit 140.

[0049] As shown in FIG. 4, on the side surface of the housing portion 140, an electrical insulating portion 20A, an electrical resistance portion 10, an electrical insulating portion 20B, a thermal diffusion layer 30, a heat insulating layer 40, and a heat shrink tube 50 are laminated.

[0050] In this specification and drawings, elements having substantially the same functional configuration may be distinguished by adding different alphabets after the same reference numeral. For example, multiple elements having substantially the same functional configuration may be distinguished as electrical insulation units 20A and 20B as necessary. However, when there is no need to distinguish between multiple elements having substantially the same functional configuration, only the same reference numeral may be used. For example, when there is no need to distinguish between electrical insulation units 20A and 20B, they are simply referred to as electrical insulation unit 20.

[0051] In these figures, the direction in which the stick-shaped substrate 150 is inserted into the heating unit 121 is also referred to as the downward direction. The direction in which the stick-shaped substrate 150 is removed from the heating unit 121 is also referred to as the upward direction. In other words, the up-down direction is the direction in which the stick-shaped substrate 150 is inserted and removed. The up-down direction corresponds to the longitudinal direction of the storage unit 140.

[0052] In addition, a direction perpendicular to the up-down direction and along the outer periphery in a cross section perpendicular to the longitudinal direction of storage unit 140 is also referred to as a left-right direction. When storage unit 140 is configured in a cylindrical shape as shown in Fig. 3, the left-right direction corresponds to a circumferential direction in a circular cross section perpendicular to the longitudinal direction of storage unit 140.

[0053] Each component of the heating unit 121 will be described in detail below.

[0054] The electric resistance portion 10 generates heat due to the electric power supplied from the power supply portion 111. More specifically, the electric resistance portion 10 generates Joule heat when a current flows through it. The electric resistance portion 10 is formed of, for example, SUS (Steel Use Stainless). In that case, the electric resistance portion 10 can exhibit high heat resistance.

[0055] As an example, the electrical resistance portion 10 may be a conductive track. The conductive track is wound around the periphery of the housing portion 140. Depending on the distribution of the conductive track around the periphery of the housing portion 140, the side surface of the housing portion 140 can be heated with an arbitrary heat distribution.

[0056] The electrical insulating part 20 is a film-like member having electrical insulation properties. The electrical insulating part 20 may be a film. Alternatively, the film as the electrical insulating part 20 may be a varnish. In the storage section 140 The electrical insulating portion 20 may be formed by coating. The electrical insulating portion 20 is made of any material having electrical insulation properties. For example, the electrical insulating portion 20 is made of polyimide. With this configuration, the electrical insulating portion 20 can exhibit high heat resistance.

[0057] The electrical resistance portion 10 is disposed on the electrical insulation portion 20. In particular, the heating portion 121 may have two electrical insulation portions 20 (20A and 20B), and the electrical resistance portion 10 may be sandwiched between the two electrical insulation portions 20. This configuration prevents the electrical resistance portion 10 from coming into contact with another conductor and causing a short circuit.

[0058] As shown in FIG. 2 and FIG. 3, the electrical insulation part 20 has a notch 90 (90A to 90C). Therefore, the heating part 121 covers the side surface of the storage part 140 except for the notch 90. On the other hand, the side surface of the storage part 140 is exposed at the notch 90. With this configuration, when the side surface of the storage part 140 is uneven, the heating part 121 can be in close contact with the side surface of the storage part 140 while avoiding the unevenness of the side surface of the storage part 140 by the notch 90. If there is no notch 90, the heating part 121 will float at the uneven part of the side surface of the storage part 140, and the temperature of the floated part may rise suddenly, causing damage to the heating part 121. In this regard, with this configuration, the heating part 121 is in close contact with the side surface of the storage part 140, so that damage to the heating part 121 can be prevented. In this way, appropriate heating of the stick-shaped substrate 150 is realized.

[0059] 2 and 3, the electrical insulating section 20 has two or more cutouts 90 formed in a staggered manner. Since the electrical resistance sections 10 are disposed on the electrical insulating section 20 and not in the cutouts 90, if the cutouts 90 are disposed in an uneven direction, the distribution of the electrical resistance sections 10 will be uneven accordingly. In this regard, with this configuration, it is possible to reduce the uneven distribution of the electrical resistance sections 10 caused by the provision of the cutouts 90. Therefore, it is possible to heat the stick-shaped substrate 150 more uniformly.

[0060] 2, two or more notches 90 are formed alternately in the left-right direction. For example, notch 90A is formed on the lower side, notch 90B is formed on the upper side, and notch 90C is formed on the lower side. With this configuration, the heating unit 121 can uniformly cover the side surface of the storage unit 140 in the left-right direction and uniformly heat the stick-shaped substrate 150.

[0061] As shown in FIG. 2, the electrical insulation section 20 according to this embodiment is formed in an M-shape having three notches 90 and three folds (that is, second portions 22A to 22C).

[0062] That is, the electrical insulation part 20 has four first parts 21 (21A to 21D) extending in the up-down direction and three second parts 22 (22A to 22C) connecting the ends of two first parts 21 adjacent in the left-right direction. The two first parts 21 connected by the second part 22 are separated in the left-right direction with a notch 90 between them. More specifically, the second part 22A connects the upper ends of the first part 21A and the first part 21B. The first part 21A and the first part 21B are separated with a notch 90A between them. The second part 22B connects the lower ends of the first part 21B and the first part 21C. The first part 21B and the first part 21C are separated with a notch 90B between them. The second part 22C connects the upper ends of the first part 21C and the first part 21D. The first portion 21C and the first portion 21D are separated from each other with a notch 90C therebetween.

[0063] The two second portions 22 connected to the same first portion 21 are spaced apart in the vertical direction. Specifically, the second portion 22A and the second portion 22B connected to the first portion 21B are spaced apart in the vertical direction. The second portion 22B and the second portion 22C connected to the first portion 21C are spaced apart in the vertical direction.

[0064] The electrical insulation part 20 covers less than 50% of the side surface of the housing part 140 in all cross sections perpendicular to the vertical direction. In the cross section taken along the AA line in FIG. 2, the electrical insulation part 20 covers 11.8 mm ((1.5 mm+2.9 mm+1.5 mm)×2), which is less than 50% of the total length of the side surface of the housing part 140, 23.7 mm. In the cross section taken along the BB line, the electrical insulation part 20 covers 11.6 mm (2.9 mm×4), which is less than 50% of the total length of the side surface of the housing part 140, 23.7 mm. In the cross section taken along the CC line, the electrical insulation part 20 covers 11.7 mm ((1.5 mm+2.9 mm+1.5 mm)+2.9 mm×2), which is less than 50% of the total length of the side surface of the housing part 140, 23.7 mm. According to this configuration, the electrical resistance portion 10 also covers less than 50% of the side surface of the housing portion 140 in all cross sections perpendicular to the up-down direction. Therefore, it is possible to prevent the stick-shaped substrate 150 from being excessively heated.

[0065] 2 and 3, the electrical resistance portion 10 is provided by folding back together with the folding back of the electrical insulation portion 20 along the shape of the electrical insulation portion 20. That is, the electrical resistance portion 10 is formed in an M-shape having three notches 90 and three folds. Two paths are provided in the first portion 21. With this configuration, the electrical resistance portion 10 is disposed over a larger portion of the side surface of the accommodation portion 140, thereby improving the heating efficiency.

[0066] As shown in FIG. 3 and FIG. 4, the thermal diffusion layer 30 is disposed so as to cover the outside of the heating unit 121. The thermal diffusion layer 30 is a member that diffuses heat. The thermal diffusion layer 30 is formed of, for example, copper, graphite, or aluminum. For example, the thermal diffusion layer 30 is formed in a film shape, covers the outside of the accommodation unit 140 and the heating unit 121 disposed around the accommodation unit 140, and is disposed in close contact with the outside of the heating unit 121 or the outside of the accommodation unit 140 corresponding to the notch 90. With this configuration, the heat generated from the heating unit 121 can be diffused over the entire side surface of the accommodation unit 140. Therefore, it is possible to reduce the temperature difference occurring between the part of the side surface of the accommodation unit 140 where the heating unit 121 is provided and the part where the notch 90 is provided, and to uniformly heat the stick-shaped substrate 150.

[0067] The heating unit 121 is disposed around the accommodating unit 140, and is fixed to the accommodating unit 140 by the heat shrink tube 50 while being covered by the thermal diffusion layer 30 and the heat insulating layer 40. The heat insulating layer 40 is a film-like member having a predetermined heat insulating property. For example, the heat insulating layer 40 is made of a vacuum insulation material, an aerogel insulation material, or the like. Since the thermal diffusion layer 30 is covered by the heat insulating layer 40, it is possible to prevent the heat from the heating unit 121 diffused by the thermal diffusion layer 30 from diffusing outside the heat insulating layer 40. The heat shrink tube 50 is a tubular member that shrinks when heat is applied. For example, the heat shrink tube 50 is made of a resin material. By heating the heat shrink tube 50 while the heating unit 121, the thermal diffusion layer 30, the heat insulating layer 40, and the heat shrink tube 50 are wound around the accommodating unit 140 in this order, it is possible to easily fix these components.

[0068] The heat insulating layer 40 corresponds to the heat insulating section 144 shown in Fig. 1. Of course, the heat insulating layer 40 may be provided separately from the heat insulating section 144 shown in Fig. 1.

[0069] The heating section 121 may have multiple regions that generate heat at different temperatures in the vertical direction. As an example, the heating section 121 may have a high heating area that generates heat at a high temperature and a low heating area that generates heat at a low temperature. With this configuration, it is possible to heat the stick-shaped substrate 150 with an optimal temperature distribution.

[0070] The electrical resistance parts 10 may be distributed unevenly in the vertical direction. For example, the electrical resistance parts 10 may be distributed at different densities in the high heating area and the low heating area. With this configuration, it is possible to make the heating part 121 generate heat at different temperatures in the vertical direction.

[0071] <3. Supplementary Information> Although the preferred embodiment of the present invention has been described in detail above with reference to the accompanying drawings, the present invention is not limited to such an example. It is clear that a person having ordinary knowledge in the technical field to which the present invention pertains can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0072] For example, in the above embodiment, an example in which two or more notches 90 are formed alternately in the left-right direction has been described, but the present invention is not limited to such an example. Two or more notches 90 may be formed alternately in other directions, such as the up-down direction. Even in this case, the heating unit 121 can uniformly cover the side surface of the storage unit 140 and uniformly heat the stick-shaped substrate 150.

[0073] For example, in the above embodiment, an example has been described in which the electrical insulation part 20 has three notches 90, but the present invention is not limited to such an example. It is sufficient that the electrical insulation part 20 has one or more notches 90. In other words, it is sufficient that the electrical insulation part 20 has two or more first portions 21 and one or more second portions 22. The number of notches 90 may be set arbitrarily depending on the shape of the accommodation part 140, etc.

[0074] Specifically, in the above embodiment, an example in which the electrical insulation part 20 is formed in an M-shape having three notches 90 and three folds has been described, but the present invention is not limited to such an example. For example, the electrical insulation part 20 may be formed in a zigzag shape. The zigzag shape here refers to a shape having four or more notches 90 and four or more folds.

[0075] For example, in the above embodiment, an example has been described in which the electrical resistance portion 10 is folded back along the shape of the electrical insulation portion 20 together with the folding back of the electrical insulation portion 20, but the present invention is not limited to such an example. That is, the number of folds of the electrical resistance portion 10 and the number of folds of the electrical insulation portion 20 may be different. Such an example will be described with reference to FIG. 5. FIG. 5 is a planar development of a heating portion 121 according to a modified example. As shown in FIG. 5, the electrical insulation portion 20 according to this modified example has one notch 90 and one fold back (i.e., the second portion 22). That is, the electrical insulation portion 20 has two first portions 21 and one second portion 22. In contrast, the electrical resistance portion 10 is folded back five times in each of the first portion 21A and the first portion 21B. In this way, the number of folds of the electrical resistance portion 10 may be greater than the number of folds of the electrical insulation portion 20.

[0076] For example, in the above embodiment, an example has been described in which the thermal diffusion layer 30 is disposed to cover the outside of the heating unit 121, but the present invention is not limited to such an example. For example, the thermal diffusion layer 30 may be disposed between the heating unit 121 and the storage unit 140. In that case, the insulating layer 40 is disposed to cover the outside of the heating unit 121. Even with such a configuration, it is possible to diffuse the heat generated from the heating unit 121 over the entire side surface of the storage unit 140, thereby uniformly heating the stick-shaped substrate 150.

[0077] For example, in the above embodiment, an example has been described in which the heating unit 121, the thermal diffusion layer 30, and the insulating layer 40 are fixed to the storage unit 140 by the heat shrink tube 50, but the present invention is not limited to such an example. For example, the heating unit 121, the thermal diffusion layer 30, and the insulating layer 40 may be fixed by a clip. The clip here is a member that holds an object, for example, holding the storage unit 140 from the front and rear. Alternatively, at least one of the thermal diffusion layer 30 and the insulating layer 40 may be configured as a clip and hold the storage unit 140.

[0078] For example, in the above embodiment, the storage section 140 is configured to be cylindrical, but the present invention is not limited to this example. The cross-sectional shape of the storage section 140 may be elliptical or polygonal.

[0079] The following configurations also fall within the technical scope of the present invention. (1) a container into which the aerosol product is inserted; a heating section for heating the aerosol product inserted in the container; A power supply unit that supplies power to the heating unit; Equipped with The heating unit includes: a film-like electrical insulating portion having one or more notches; an electrical resistance portion that is disposed on the electrical insulation portion and generates heat by the power supplied from the power supply portion; and arranged around the housing portion.
