[0007] Patent Document 3: International Publication No. 2016 / 207407 Summary of the Invention

[0008] According to a first aspect of the present invention, a smoking system is provided, comprising a consumable having a smokeable substance and a device for heating the smokeable substance to atomize it. The device includes a chamber for receiving the consumable and a heating portion for heating the consumable received in the chamber. The chamber includes an opening for inserting the consumable and a holding portion for holding the consumable. The holding portion includes a pressing portion for pressing a portion of the consumable and a non-pressing portion. The pressing portion and the non-pressing portion each have an inner surface and an outer surface. The heating portion is disposed on the outer surface of the pressing portion. The inner surface of the pressing portion can also be considered the pressing surface for pressing the consumable, and the inner surface of the non-pressing portion can also be considered the non-pressing surface for not pressing the consumable.

[0009] According to the first method, the consumable is substantially in close contact with the heating surface (the inner surface of the pressing part), thus enabling efficient heat transfer from the heating part to the consumable. Furthermore, the consumable includes a smokeable substance containing tobacco or non-tobacco. The consumable may or may not have an interface tube. A consumable with an interface tube may be a rod-shaped product similar in appearance to conventional cigarettes containing tobacco or other smokeable substances. A consumable without an interface tube may be a consumable in which the smokeable substance, such as tobacco, is fixed into a flat plate shape, or a consumable in which the smokeable substance is wrapped with a breathable component such as non-woven fabric or a sheet component such as paper. Additionally, the heating part may also have a heating element. The chamber may be, for example, a bottomed cylindrical container or a bottomless cylindrical body. The chamber is preferably made of a material with high thermal conductivity, such as stainless steel. This allows for effective heating. It is preferable that the wall thickness of the chamber is uniform (including substantially uniform cases). This allows for more uniform heating of the entire chamber. The thickness of the chamber is, for example, 0.04 mm to 1.00 mm, preferably 0.04 mm to 0.50 mm, and more preferably 0.05 mm to 0.10 mm.

[0010] The heating element is preferably disposed on the outer surface of the pressing part without any gap (without any gap between the heating element and the outer surface of the pressing part). Here, "without any gap" also means substantially without any gap. Therefore, the heating element is in close contact with the outer surface of the pressing part, thus enabling more efficient transfer of heat from the heating element to the consumable. Alternatively, the heating element may include an adhesive layer. In this case, it is preferable that the heating element including the adhesive layer is disposed on the outer surface of the pressing part without any gap.

[0011] The opening is preferably designed to accommodate consumables without pressing them down. This allows for easy insertion of consumables into the chamber. The shape of the chamber opening on a plane orthogonal to the length direction of the chamber—in other words, the direction in which the consumable is inserted—or the direction extending along the entire side of the chamber (hereafter referred to only as the length direction of the chamber), can be polygonal or elliptical, but is preferably circular. This allows for easy insertion of consumables into the opening.

[0012] The inner circumference length of the holding portion is preferably the same as the outer circumference length of the consumable before it is pressed by the pressing portion. Furthermore, "same" here includes the case of being substantially the same. "Substantially the same" means that the difference between the inner circumference length of the holding portion and the outer circumference length of the consumable before it is pressed by the pressing portion is, for example, within ±6% of the inner circumference length of the holding portion, preferably within ±4%, and more preferably within ±2%. As described above, the holding portion has a pressing portion and a non-pressing portion. When the inner circumference length of the holding portion is substantially the same as the outer circumference length of the consumable, by pressing a portion of the consumable by the pressing portion, the outer circumference shape of the consumable is made to substantially match the cross-sectional shape of the inner surface of the holding portion. Compared to the case where the inner circumference length and inner circumference shape of the holding portion are the same as the outer circumference length and outer circumference shape of the consumable, the portion of the consumable pressed by the pressing portion is formed in this smoking system, thus improving the heat transfer efficiency from the heating portion to the consumable. Furthermore, compared to the case where the outer perimeter of the consumable is shorter than the inner perimeter of the retainer, the unpressed portion of the outer perimeter of the consumable is in substantial contact with the inner perimeter of the retainer (the non-pressed surface), thus improving the heat transfer efficiency from the heating element to the consumable. Moreover, compared to the case where the outer perimeter of the consumable is longer than the inner perimeter of the retainer, the consumable can be smoothly inserted into the retainer, suppressing density strain on the outer perimeter of the consumable and its interior (e.g., tobacco, as an example of a smokeable substance). As a result, uneven heating caused by density strain within the consumable and deviations in the airflow resistance of each consumable can be suppressed. Additionally, it can be said that the inner perimeter of the retainer is preferably substantially the same as the outer perimeter of the consumable in the pressed state, or the inner perimeter of the retainer can be the inner perimeter of the plane of the retainer orthogonal to the length direction of the chamber. Additionally, "the outer perimeter length of the consumable before being pressed by the pressing part" can also be the outer perimeter length of the portion of the consumable before being pressed by the pressing part, located in the length direction of the chamber corresponding to the inner perimeter length of the comparison holding part when pressed by the pressing part. Furthermore, "the outer perimeter length of the consumable in the state of being pressed by the pressing part" can also be the outer perimeter length of the consumable in the state of being pressed by the pressing part, located in the length direction of the chamber corresponding to the inner perimeter length of the comparison holding part.

[0013] Preferably, the outer peripheral surface of the retaining part has the same shape and size along the entire length of the chamber (the outer peripheral length of the retaining part on the plane orthogonal to the length of the chamber). This prevents the heating part from being loosely disposed on the outer surface of the pressing part of the retaining part, resulting in the ability to easily and substantially seamlessly dispose of the heating part on the outer surface of the pressing part.

[0014] The non-pressing portion preferably contacts the consumable in a non-pressing state when the consumable is positioned in the desired location within the chamber. This non-pressing state substantially includes a non-pressing state. Therefore, no gap is substantially created between the consumable and the holding portion, thus further improving the heat transfer efficiency from the heating portion to the consumable in the non-pressing portion. The non-pressing portion may also have an inner surface that connects to opposing pressing portions with planar inner surfaces, and this inner surface may be curved.

[0015] The inner surface of the non-pressable portion of the holding part is preferably a curved surface that connects the circumferential ends of the chambers of the inner surface of the pressing part to each other. This further simplifies the construction of the smoking system, and makes cleaning the non-pressable portion easier compared to cases where the inner surface has angles. When the gap is formed within the chamber, as described later, cleaning the gap is easier compared to cases where the inner surface has angles. Preferably, the shape of the surface of the inner surface of the non-pressable portion orthogonal to the length direction of the chamber is the same at any position in the length direction of the chamber as the shape of the opening on the surface orthogonal to the length direction of the chamber. In other words, the inner surface of the non-pressable portion is preferably formed by extending the inner surface of the chamber forming the opening along the length direction. This simplifies the chamber structure, and when the gap is formed within the chamber, as described later, it prevents obstruction of airflow entering from the opening of the chamber. Furthermore, cleaning the gap is easier. Additionally, "circumferential direction of the chamber" can also be considered as "the direction of rotation about the length direction of the chamber".

[0016] The outer surface of the pressing part can be curved or uneven, but it is preferably flat. Furthermore, "flat" here includes cases where it is substantially flat. "The outer surface of the pressing part is substantially flat" means that, from the perspective of the proportion of the flat surface relative to the entire outer surface of the pressing part, the proportion of the flat surface relative to the entire outer surface of the pressing part is, for example, 80% or more, preferably 90% or more, and more preferably 95% or more.

[0017] By making the outer surface of the pressing part flat, when the strip electrode is connected to the heating part disposed on the outer surface of the pressing part, the deflection of the strip electrode can be suppressed, thus making it easier to wind the electrode within the device. In addition, compared with the case where the outer surface of the pressing part is curved or uneven, the heating part can be positioned with high precision, and the heating part can be easily disposed on the outer surface of the pressing part without gaps.

[0018] The inner surface of the pressing part is preferably flat. This facilitates the insertion of consumables. "Flat" here also includes cases where it is substantially flat. Furthermore, the thickness of the pressing part is preferably uniform. This allows for more uniform heating. "Uniform thickness" here also includes cases where it is substantially uniform. The thickness of the pressing part is, for example, 0.04 mm to 1.00 mm, preferably 0.04 mm to 0.50 mm, and more preferably 0.05 mm to 0.10 mm. This prevents the pressing part from becoming too large, which could hinder efficient heat transfer to the consumable, and ensures the necessary strength of the pressing part.

[0019] When the inner surface of the pressing part is flat, the chamber may have only one pressing part, but it is preferable to have two or more pressing parts in the circumferential direction of the chamber. Thus, since there are two or more pressing points for the consumable in the circumferential direction of the chamber, the consumable can be heated more comprehensively and evenly.

[0020] The retaining part has two opposing pressing parts, and the distance between at least a portion of the inner surfaces of the two pressing parts is preferably smaller than the width of the portion disposed between the pressing parts of the consumable inserted into the chamber. The inner surfaces of the two opposing pressing parts of the retaining part may also be planar.

[0021] When the inner surface of the pressing part is flat, there may be three or more pressing parts in the circumferential direction of the chamber. Each pressing part may be configured to face each other or to face each non-pressing part. When configured to face each non-pressing part, the distance between the point where the lines extending perpendicularly from the center of the inner surface of each pressing part intersect on a plane orthogonal to the longitudinal direction of the chamber and the center of the inner surface of each pressing part may be smaller than the radius of the inserted consumable with a circular cross-section. Here, "circular" also includes cases where it is substantially circular.

[0022] Preferably, the inner surface of the pressing part has a pair of opposing planar pressing surfaces, and the inner surface of the non-pressing part has a pair of opposing curved non-pressing surfaces connecting the two ends of the pair of planar pressing surfaces. The curved non-pressing surfaces may have an arc-shaped cross-section on a plane orthogonal to the length direction of the chamber. The holding part may be constructed of a metal cylindrical body with a uniform thickness. Here, uniform thickness includes substantially uniform thickness. This simplifies the construction of the chamber and facilitates high-precision manufacturing. In addition, this allows for a well-balanced and uniformly positioned arrangement of the pressing and non-pressing parts, making heating more uniform. It also facilitates the precise and gapless placement of the heating part on the outer surface of the pressing part, thereby improving heating efficiency. The thickness of the holding part is, for example, 0.04 mm to 1.00 mm, preferably 0.04 mm to 0.50 mm, and more preferably 0.05 mm to 0.10 mm. Therefore, it is possible to suppress the inefficient heat transfer to consumables caused by excessively large holding parts, and to ensure the necessary strength of the holding parts.

[0023] The retaining part may also have a gap. When the consumable is positioned in the desired position in the chamber, this gap connects the inner surface of the non-pressing part and the consumable to the opening of the chamber and the end face of the consumable positioned in the desired position in the chamber, or the opening of the chamber and the end face of the consumable positioned in the chamber and away from the opening of the chamber. The gap is a flow path for air to flow from the opening of the chamber toward the end face of the consumable when the user inhales. This eliminates the need for a separate flow path for introducing air to the consumable in the smoking system, thus simplifying the construction of the smoking system. Furthermore, since a portion of the non-pressing part forming the gap is exposed, the gap can be easily cleaned. Additionally, the air passing through the gap can be efficiently heated, effectively utilizing the heat energy from the heating unit. From the viewpoint of ventilation resistance, the height of the gap (the distance between the inner surface of the longest non-pressing part and the consumable on a line extending radially from the center of the cross-section of the consumable positioned in the desired location in the chamber) is preferably 0.1 mm to 1.0 mm or less, more preferably 0.2 mm to 0.8 mm or less, and most preferably 0.3 mm to 0.5 mm or less.

[0024] For example, the retaining part preferably has at least two pressing parts separated circumferentially within the chamber and is provided with gaps. When the consumable is positioned at the desired location within the chamber, these gaps connect the inner surfaces of the non-pressing parts connecting the two pressing parts to the consumable, either between the opening of the chamber and the end face of the consumable positioned at the desired location within the chamber, or between the opening of the chamber and the end face of the consumable positioned within the chamber and away from the opening of the chamber. More preferably, two gaps are provided between the inner surfaces of the two non-pressing parts connecting the two pressing parts and the consumable. Even more preferably, three or more gaps are provided between the inner surfaces of the three or more non-pressing parts connecting three or more pressing parts and the consumable. This further suppresses the deflection of airflow within the chamber and inhibits more uniform heating.

[0025] The two pressing parts are preferably opposite each other. In this case, the deviation of the airflow in the chamber can be further suppressed, and obstacles to more uniform heating can be further suppressed. Alternatively, the two pressing parts are preferably parallel to each other. In this case, since the consumable is pressed by the two parallel pressing parts opposite each other, the consumable can be heated evenly from both sides, and aerosol can be generated efficiently.

[0026] Preferably, the retaining part has no protrusions on its inner surface. If the inner surface of the retaining part, which has a uniform thickness, has protrusions, resulting in a recess on the outer surface of the retaining part, it may be difficult to position the heating part seamlessly on the outer surface of the pressing part. Furthermore, protrusions on the inner surface of the retaining part can cause uneven thickness, hindering uniform heating. However, by ensuring that the retaining part has no protrusions on its inner surface, these problems can be avoided.

[0027] The chamber preferably has a first guide portion, which has a conical surface connecting the inner surface of the chamber forming the opening to the inner surface of the pressing portion. The first guide portion allows the cross-sectional shape of the inner surface of the chamber to change continuously from the opening toward the pressing portion, thus enabling smooth insertion of the consumable into the chamber. Preferably, no heating portion is disposed on at least one of the outer surfaces of the chamber selected between the opening and the first guide portion, the outer surface of the first guide portion, and the outer surface of the non-pressing portion. Since the consumable is not pressed on the inner surfaces corresponding to these outer surfaces, energy can be used efficiently for heating by not disposing of heating portions on these outer surfaces.

[0028] Preferably, the chamber has a cylindrical non-holding portion between the opening and the holding portion. When the consumable is positioned in the desired location within the chamber, the gap between the inner surface of the non-holding portion and the consumable is, for example, 3.0 mm or less, preferably 1.0 mm or less, and more preferably 0.5 mm or less but more than 0.4 mm. If the gap is within these ranges, the consumable can be heated efficiently via the non-holding portion, thus suppressing the condensation of aerosols passing through the interior of the consumable. Furthermore, with the aforementioned gap present, the air passing through the gap can be heated efficiently, effectively utilizing the heat energy from the heating element. Moreover, by making the gap 0.4 mm or more, it is easy to insert the consumable into the chamber. In addition, in this specification, "the state in which the consumable is positioned in the desired position in the chamber" refers to the state in which the consumable is correctly positioned in the intended position in the chamber in order to generate aerosol from the consumable (for example, in the case where the chamber has a "bottom that is abutted by the inserted consumable", the consumable abuts at least a portion of the bottom, or in the case where the device has an "abutting portion that is abutted by the inserted consumable" inside or outside the chamber, the consumable abuts at least a portion of the abutting portion).

[0029] The chamber may have a bottom. Alternatively, the device may have an abutment portion inside or outside the chamber for a consumable inserted into the chamber to abut. The bottom or abutment portion preferably supports a portion of the consumable positioned at a desired location within the chamber in a manner that exposes at least a portion of the end face of the consumable. Furthermore, in the case where the smoking system has the aforementioned gap, the bottom or abutment portion preferably supports a portion of the consumable in a manner that communicates with the gap through the exposed end face of the consumable. This allows air to be drawn from the end face of the consumable and enables positioning of the consumable in the longitudinal direction. Alternatively, the bottom of the chamber may have a bottom wall and side walls, with the width of the bottom, defined by the side walls, decreasing towards the bottom walls. This allows positioning of the consumable by compressing it using the side walls when it reaches the bottom of the chamber. Alternatively, the bottom or abutment portion of the chamber may have a bottom wall or abutment surface, with a protrusion or groove. Alternatively, the bottom or abutment of the chamber may have a bottom wall or abutment surface, and the bottom wall or abutment surface may have holes for obtaining air into the chamber.

[0030] The chamber may also have a cylindrical component with an opening on at least one side. The heating element may also be configured to heat all pressing parts simultaneously, or it may heat them within the same time period.

[0031] The heating element is preferably arranged covering the entire outer surface of the pressing element. This allows for more uniform heat transfer from the heating element to the pressing element, resulting in efficient heating of the consumable held in the holding part.

[0032] The device may also have a strip-shaped electrode extending from the heating element. Since the electrode is strip-shaped, the reliability of power supply to the heating element is improved compared to a rope-shaped electrode. Preferably, the strip-shaped electrode extends from the outer surface of the planar pressing element to the outside of the outer surface of the pressing element, with the heating element disposed on the outer surface of the pressing element. As mentioned earlier, by making the outer surface of the pressing element planar, deflection of the strip-shaped electrode can be suppressed, thus facilitating the winding of the electrode within the device.

[0033] The strip electrode can also extend from only one outer surface of the two pressing parts. In this case, since the strip electrode is concentrated, the device can be miniaturized. Alternatively, the strip electrode can extend from the outer surface of each of the two pressing parts. In this case, multiple independent heating parts can be provided using each strip electrode, or the positive and negative electrodes can be extended separately depending on the component configuration of the device. The strip electrode can also extend to the opposite side of the opening side of the chamber. In this case, since no electrode is provided on the opening side of the chamber where the consumable is inserted, the device can have a simple structure, and the reliability of the device can be improved. The strip electrode can also have a structure in which a layer of conductive tracks is disposed between layers of a double-layer electrically insulating material. The electrically insulating material is, for example, polyimide, and the conductive tracks can be formed, for example, gold, silver, copper, nickel, alloys containing them, or multiple combinations of these metals or alloys. Thus, a flexible heating structure that is easy to manufacture and has high reliability can be obtained.

[0034] The heating element is preferably an electrically insulating member having a heating element and at least one side covering the heating element. Furthermore, the electrically insulating member is preferably disposed within a region of the outer surface of the retaining portion. In other words, the electrically insulating member is preferably configured so that it does not protrude from the outer surface of the retaining portion on the side of the first guide portion in the longitudinal direction of the chamber. As described above, when the first guide portion is provided between the opening and the pressing portion, the shape of the outer surface of the chamber and the outer perimeter length of the chamber on the plane orthogonal to the longitudinal direction of the chamber can be changed in the first guide portion and the retaining portion. Therefore, by disposing the electrically insulating member only on the outer surface of the retaining portion, relaxation can be suppressed.

[0035] The device preferably includes a sheet (fixed sheet) that covers the chamber and the heating element and fixes the heating element to the outer surface of the chamber. Examples of sheets that fix the heating element include shrinkable sheets that shrink under certain external forces; specifically, heat-shrinkable sheets that shrink when heated. Preferably, the fixed sheet, such as the shrinkable sheet, has a higher circumferential shrinkage rate than the longitudinal shrinkage rate of the chamber when covering the chamber and the heating element. The heat-shrinkable sheet may also contain polyimide, polypropylene, polyethylene terephthalate, gelatin, polysaccharides, etc. Using a fixed sheet, the heating element can be firmly and tightly fixed to the outer surface of the chamber, thus further improving heating efficiency and stabilizing the structure around the chamber. Furthermore, the sheet is preferably disposed on the outer surface of the retaining portion. In other words, the sheet is preferably disposed such that it does not protrude from the outer surface of the retaining portion on the side of the first guide portion in the longitudinal direction of the chamber. As described above, when a first guide portion is provided between the opening and the retaining portion, the shape of the outer surface of the chamber and the outer perimeter of the chamber on a plane orthogonal to the length direction of the chamber can be changed in the first guide portion and the retaining portion. Therefore, by providing a sheet only on the outer surface of the retaining portion, relaxation can be suppressed.

[0036] The heating section may also have a first part located on the side opposite to the opening and a second part located on the opening side. Preferably, the heater power density of the second part is higher than that of the first part, or the heating rate of the second part is higher than that of the first part, or the heating temperature of the second part is higher than that of the first part in any given time interval. Preferably, the second part, when the consumable is positioned in the desired location within the chamber, covers the outer surface of the holding portion corresponding to at least half of the smokeable material contained in the consumable along its length. Accordingly, energy consumption can be suppressed while shortening the time from activating the heating section to the first smoking.

[0037] With the consumable positioned in the desired location within the chamber, the upstream end (upstream in the direction of air and aerosol flow when the user inhales; the same applies hereinafter) of the heating section or heating element disposed on the outer surface of the pressing part is preferably located downstream (downstream in the direction of air and aerosol flow when the user inhales; the same applies hereinafter) of the upstream end of the consumable's smokeable portion. For example, the upstream end of the heating section or heating element is located 1.0 mm to 10.0 mm downstream of the upstream end of the consumable's smokeable portion positioned in the desired location within the chamber, preferably 3.0 mm to 6.0 mm, and more preferably 4.5 mm to 5.5 mm. This suppresses aerosol leakage from the upstream end of the smokeable portion. Furthermore, it has a positive effect on the inhalation flavor.

[0038] With the consumable positioned in the desired location within the chamber, it is preferable that the downstream end of the heating element or heating section disposed on the outer surface of the pressing part is located further downstream than the downstream end of the smoke-absorbing portion of the consumable. For example, the downstream end of the heating element or heating section is located 1.0 mm to 10.0 mm downstream of the downstream end of the smoke-absorbing portion of the consumable positioned in the desired location within the chamber, preferably 2.0 mm to 5.0 mm, and more preferably 2.0 mm to 3.0 mm. This suppresses both energy consumption and aerosol condensation.

[0039] The electric power density of the heater on the outer surface of the pressing part is preferably higher than that of the heater covering the outer surface of the non-pressing part; or, the heating rate of the heater on the outer surface of the pressing part is preferably higher than that of the heater covering the outer surface of the non-pressing part; or, the heating temperature of the heater on the outer surface of the pressing part is preferably higher than that of the heater covering the outer surface of the non-pressing part at any given time. Accordingly, when the area of ​​the pressing part in the holding part is a certain size larger than the area of ​​the non-pressing part, heating of the smokeable material can be performed more efficiently. The electric power density of the heater on the outer surface of the pressing part can also be the same as that of the heater covering the outer surface of the non-pressing part. The heating rate of the heater on the outer surface of the pressing part can also be the same as that of the heater covering the outer surface of the non-pressing part. The heating temperature of the heater on the outer surface of the pressing part can also be the same as that of the heater covering the outer surface of the non-pressing part. Furthermore, "same" here includes cases where they are substantially the same.

[0040] Alternatively, the heating part may have a heating element, which is a heating track. The outer surfaces of the pressing part and the non-pressing part may be connected at an angle, forming a boundary between them. Preferably, the heating track extends only along a direction intersecting the direction of the boundary, and more preferably, it extends at a right angle to the direction of the boundary. This makes the heating track difficult to break and difficult to peel off from the outer surface of the holding part. Furthermore, "right angle" here also includes cases where the direction is substantially right-angled.

[0041] The heating element can be, for example, a sheet heater. The sheet heater can have a structure in which a layer of electrically insulating material is overlapped with a layer of heating rails, which is an example of a heating element. Alternatively, the heating element can have a structure in which a layer of heating rails is disposed between two layers of electrically insulating material. The electrically insulating material is, for example, polyimide, and the heating rails can be, for example, metals such as stainless steel. This results in a flexible heating structure that is easy to manufacture and has high reliability.

[0042] Alternatively, the consumable may include a first part having a first hardness and a second part having a second hardness, wherein the second part is a part that is different from the first part in the insertion direction of the consumable, and the first part is disposed at the end side of the consumable along the length direction than the second part.

[0043] When the consumable is positioned in the desired location within the chamber, the consumable is preferably pressed against the inner surface of the pressing portion, with at least a portion of the consumable positioned as the first part pressed against it. Furthermore, the first hardness is, for example, 65% or more and 90% or less, preferably 70% or more and 85% or less, more preferably 73% or more and 82% or less, and most preferably 77% or more and 81% or less. This allows the consumable to easily maintain its shape and facilitates insertion into the holding portion.

[0044] When the consumable is positioned in the desired location within the chamber, the consumable is preferably pressed against the inner surface of the pressing portion, with at least a portion of it positioned as the second part. Furthermore, the second hardness is, for example, 90% or more and 99% or less, preferably 90% or more and 99% or less, more preferably 92% or more and 98% or less, and most preferably 95% or more and 98% or less. This facilitates insertion and securely holds the consumable.

[0045] The second hardness is preferably higher than the first hardness. This allows for both easy insertion of the consumable into the retaining part and secure retention of the consumable. Furthermore, when the consumable is inserted into the chamber, the change from a state where only the first part is pressed against the inner surface of the pressing part to a state where the second part is also pressed against the inner surface of the pressing part allows the user to feel the change in resistance during insertion. As a result, the user can discern the extent to which the consumable is inserted into the chamber during insertion, providing a clue as to how much further insertion is needed before reaching the desired position, thus facilitating easy placement of the consumable in the desired location. Preferably, the first and second parts are arranged adjacent to each other to allow the user to more clearly feel the change in resistance. Furthermore, the difference between the first and second hardness is preferably at least 4%, more preferably at least 10%, and most preferably at least 14%.

[0046] The term "hardness" as used throughout this specification refers to the resistance to deformation. Hardness is generally expressed as a proportion. In the case where the consumable is a cylindrical rod, if the diameter of the consumable before applying the load is set as D... s Let D be the diameter of the direction in which the load is applied to the consumable under a specified load along its diameter. d Then, the deformation d of the consumable under the specified load can be determined by D. s -D dThe hardness (%) is expressed as Dd / Ds × 100 (%). The harder the material constituting the consumable, the closer the hardness is to 100%.

[0047] According to ISO 187, at an ambient temperature of 22±2 degrees Celsius and a relative humidity of 60%, using a commercially available device under the trade name HardnessTester H10 (Borgwaldt KC GmbH, Hamburg, Germany), with an applied load of 88 grams, D was measured 5 seconds after the load was applied. d The determination.

[0048] The length of the first portion of the consumable is less than or equal to the length of the inner surface of the pressing portion in the longitudinal direction. When the consumable is positioned in the desired location within the chamber, it is preferable to position the consumable in the chamber such that the first portion of the consumable does not protrude from the inner surface of the pressing portion in the longitudinal direction. Therefore, when the first portion contains smokeable material, pressing the smokeable material along its entire length in the longitudinal direction efficiently heats and atomizes the smokeable material. Furthermore, it is preferable that when the consumable is positioned in the desired location within the chamber, the entire outer peripheral surface of the smokeable material of the consumable is covered by the holding portion. Therefore, the entire outer peripheral surface of the smokeable material is directly heated by the holding portion, thus heating the smokeable material uniformly and efficiently. Additionally, it is preferable that when the consumable is positioned in the desired location within the chamber, the consumable is positioned such that at least a portion of the first portion is pressed against the inner surface of the pressing portion, and simultaneously, at least a portion of the second portion is pressed against the inner surface of the pressing portion. Therefore, when the first portion contains smokeable material, efficient heating of the smokeable material based on the pressing portion and secure retention of the consumable can be achieved simultaneously.

[0049] When the consumable is positioned at the desired location, the distance between the second part of the consumable and the retaining part is preferably 1.0 mm or more and 10.0 mm or less, more preferably 2.0 mm or more and 8.0 mm or less, and most preferably 4.0 mm or more and 6.0 mm or less. This allows for the simultaneous achievement of both adequate retaining force and ease of insertion of the consumable.

[0050] The chamber may also have a bottom or an abutment portion. The length from the bottom wall or abutment surface of the consumable abutting against the bottom or abutment portion of the chamber to the opening side of the pressing portion is preferably longer than the length of the first portion of the consumable in the longitudinal direction (hereinafter referred to as the length of the first portion), and shorter than 1.5 times the length of the first portion, more preferably shorter than 1.35 times. And / or, at least a portion of the first portion of the consumable is preferably located closer to the opening side than the center portion of the holding portion in the longitudinal direction when the consumable is positioned in the desired position in the chamber. Therefore, a change in resistance can be felt before the first portion of the consumable abuts against the bottom wall or abutment surface of the chamber, making the insertion position where this change is felt closer to the desired insertion position of the consumable, thus making it easier to position the consumable in the desired position and improving the user experience.

[0051] The first part is preferably a smokeable substance containing tobacco, an example of a flavor source. Additionally, the first part may have a sheet component that is wound around the smokeable substance and has ventilation, and a cap that is fixed to the sheet component and prevents the smokeable substance from falling off. The cap is ventilation-friendly and can be adhered to the sheet component, for example, by paste. Alternatively, the cap can be fixed to the sheet component by friction. The cap may be, for example, filter paper or an acetate filter tip. The second part may have a cylindrical component. The cylindrical component may be a paper tube or a hollow filter tip.

[0052] Hollow filter tips may include a filling layer with one or more hollow channels and a filter rod package covering the filling layer. Due to the high fiber density of the filling layer, air and aerosols flow only through the hollow channels during intake, with almost no flow within the filling layer itself. Hollow filter tips may also have an interface tube composed of adjacent filter tip sections. In consumable products, when it is desirable to reduce filtration loss due to aerosol components in the filter tip section, shortening the length of the filter tip section and replacing it with a hollow filter tip section is more effective in increasing the aerosol delivery rate.

[0053] The consumable may also include a first roll of paper containing a cigarette-eating substance. The length of the consumable in the longitudinal direction is preferably 40mm to 90mm, more preferably 50mm to 75mm, and even more preferably 50mm to 60mm. The circumference of the consumable is preferably 15mm to 25mm, more preferably 17mm to 24mm, and even more preferably 20mm to 23mm. Alternatively, the length of the cigarette-eating substance in the consumable may be 18mm to 22mm, the length of the first roll of paper may be 18mm to 22mm, the length of the hollow filter tip may be 7mm to 9mm, and the length of the filter tip may be 6mm to 8mm.

[0054] The smokeable material of consumables may contain an aerosol source that generates aerosols when heated at a specified temperature. The type of aerosol source is not particularly limited, and extracts from various natural sources and / or their constituent components may be selected depending on the intended use. Examples of aerosol sources include glycerol, propylene glycol, glyceryl triacetate, 1,3-butanediol, and mixtures thereof. The content of the aerosol source in the smokeable material (by weight % relative to the total weight of the smokeable material) is not particularly limited, but from the viewpoint of sufficiently generating aerosols and providing a good aroma, it is generally 5% by weight or more, preferably 10% by weight or more, and generally 50% by weight or less, preferably 20% by weight or less.

[0055] The smokeable material in the consumable can use tobacco flakes, stems, or other known plants as flavor sources. Furthermore, the shape of the tobacco or other flavor source can be shredded, flake, rope, powder, granules, pellets, paste, or porous. The content of the smokeable material in the consumable ranges from 200mg to 400mg, preferably 250mg to 320mg, when the size of the smokeable material is 20mm to 23mm in circumference and 18mm to 22mm in length. The moisture content of the smokeable material (by weight%) is, for example, 8% to 18% by weight, preferably 10% to 16% by weight. This moisture content inhibits the formation of paper stains and improves rolling adaptability during manufacturing. Additionally, the consumable can be easily deformed to fit the cross-sectional shape of the holding section. There are no particular limitations on the size of the tobacco shreds used as an example of a smokeable material or its preparation method. For example, dried tobacco leaves can be chopped into pieces with a width of 0.8 mm to 1.2 mm for use. Alternatively, dried tobacco leaves can be pulverized into uniform particles with an average particle diameter of approximately 20 μm to 200 μm, then processed into sheets and chopped into pieces with a width of 0.8 mm to 1.2 mm for use. Furthermore, the sheets can be pleated instead of chopped for use as a smoking compound. Additionally, the smoking compound may contain one or more flavorings. The type of flavoring is not particularly limited, but menthol is preferred for providing a good smoking experience.

[0056] The consumable can also have a second roll of paper different from the first roll, comprising a cylindrical component, a hollow filter tip, and at least one filter tip. The second roll can also be a portion of the first roll of the smokeable substance. Both the first and second rolls of the consumable can be made from base paper with a basis weight, for example, 20 gsm to 65 gsm. The thickness of the first and second rolls is not particularly limited, but from the viewpoints of rigidity, air permeability, and ease of adjustment during papermaking, a thickness of 10 μm to 100 μm is preferred.

[0057] The first and second rolls of consumable paper may contain filler. The filler content relative to the total weight of the first and second rolls can range from 10% to 60% by weight, preferably 15% to 45% by weight. In this embodiment, the filler content is preferably 15% to 45% by weight relative to the preferred basis weight range (25 gsm to 45 gsm). As fillers, examples include calcium carbonate, titanium dioxide, and kaolin. Regarding the paper containing such filler, from the viewpoint of the appearance of the consumable paper roll, a bright white color is preferred, which can permanently maintain its whiteness. By containing a large amount of such filler, for example, the ISO whiteness of the paper roll can be made to be 83% or higher. Furthermore, from a practical viewpoint of the consumable paper roll, the first and second rolls preferably have a tensile strength of 8 N / 15 mm or higher. Therefore, the paper roll is less likely to break when the consumable is pulled out from the holding section. This tensile strength can be increased by reducing the filler content. Specifically, tensile strength can be improved by reducing the filler content to less than the upper limit of the filler content shown in the above-exemplified range of weights.

[0058] The retaining part includes a first retaining part, and the chamber includes a second retaining part located further away from the opening than the first retaining part. With the consumable held in the chamber by the first and second retaining parts, the second retaining part is configured to compress the consumable more than the first retaining part, and / or, on a plane orthogonal to the length direction of the chamber, the cross-sectional area of ​​the interior of the second retaining part is smaller than the cross-sectional area of ​​the interior of the first retaining part. Therefore, the airflow resistance during smoking can be adjusted by pressing the second retaining part. Since the second retaining part is provided separately from the first retaining part, the shape of the second pressing part can be formed independently of the shape of the first pressing part, which is suitable for optimal heating, to achieve the desired airflow resistance. It is also possible not to arrange the heating part on the outer surface of the second pressing part. In particular, when the part of the consumable pressed by the second retaining part, such as the aforementioned cap, does not contain smokeable material, by not arranging the heating part in the second retaining part, heating that does not effectively contribute to the heating of the smokeable material can be suppressed, and energy can be used efficiently.

[0059] The first holding portion may also include a first pressing portion and a first non-pressing portion, which are part of the pressable consumable. The second holding portion may also include a second pressing portion and a second non-pressing portion, which are part of the pressable consumable. By having the first holding portion have a first pressing portion, the consumable is substantially in close contact with the heating surface (the inner surface of the pressing portion) in the first holding portion, thus enabling efficient transfer of heat from the heating portion to the consumable.

[0060] The chamber preferably has a second guide portion, which has a conical surface connecting the inner surface of the first pressing portion and the inner surface of the second pressing portion. The second guide portion allows the cross-sectional shape of the inner surface of the chamber to change continuously from the first pressing portion to the second pressing portion, thus enabling the consumable to be smoothly inserted into the chamber.

[0061] Alternatively, the first retaining part may have a pair of opposing first pressing surfaces, and the second retaining part may have a pair of opposing second pressing surfaces. Preferably, the shortest distance between the second pressing surfaces is smaller than the shortest distance between the first pressing surfaces. The second pressing surfaces may also be planar. Here, "planar" includes substantially planar. In the case that the second pressing surfaces are planar, in a direction orthogonal to the length direction of the chamber, the pressing surfaces of the second retaining part may also face the same direction as the pressing surfaces of the chamber of the first retaining part. This simplifies the manufacture of the chamber and makes the insertion of the consumable easier.

[0062] The second retainer can also be disposed at the end of the chamber. In particular, when the smokeable material at the front end of the consumable is pressed, the second retainer can compress the smokeable material at the front end of the consumable and integrate it, thereby reducing the possibility of the smokeable material falling into the chamber when the consumable is removed from the chamber after smoking.

[0063] According to a second aspect of the invention, a smoking system is provided, comprising a consumable having a smokeable substance and a device for heating the smokeable substance to atomize it. The device includes a chamber for receiving the consumable and a heating section for heating the consumable received in the chamber. The inner circumferential length of the chamber is the same as the outer circumferential length of the consumable received before the chamber, and the inner circumferential shape of the chamber on a plane orthogonal to the length direction of the chamber differs from the cross-sectional shape of the consumable received before the chamber, which is orthogonal to the length direction. Here, "same" includes the case of being substantially the same. "Substantially the same" means that the difference between the inner circumferential length of the chamber and the outer circumferential length of the consumable received before the chamber is, for example, within ±6% of the inner circumferential length of the chamber, preferably within ±4%, and more preferably within ±2%.

[0064] According to the second method, since the consumable is substantially in close contact with the heating surface (the inner surface of the chamber), heat from the heating element can be efficiently transferred to the consumable. Specifically, the inner circumference of the chamber is substantially the same as the outer circumference of the consumable, and the inner circumference shape of the chamber differs from the cross-sectional shape of the consumable contained within the chamber. Therefore, a portion of the consumable is pressed against the inner surface of the chamber, and the outer circumference shape of the consumable is approximately consistent with the inner circumference shape of the inner surface of the holding part. Compared to the case where the inner circumference length and shape of the chamber are the same as the outer circumference length and cross-sectional shape of the consumable, in this smoking system, a portion of the consumable is formed where it is pressed by the chamber, thus improving the heat transfer efficiency from the heating element to the consumable. Furthermore, compared to the case where the outer circumference length of the consumable is shorter than the inner circumference length of the chamber, the unpressed portion of the outer circumference surface of the consumable is also substantially in contact with the inner circumference surface of the chamber (the non-pressed surface), thus improving the heat transfer efficiency from the heating element to the consumable. Furthermore, compared to cases where the outer perimeter of the consumable is longer than the inner perimeter of the chamber, the consumable can be smoothly inserted into the chamber, and strain caused by density changes in the outer perimeter of the consumable and its interior (e.g., tobacco, as an example of a smokeable substance) can be suppressed. As a result, uneven heating and deviations in airflow resistance of each consumable caused by density strain within the consumable can be suppressed. Additionally, it can be stated that the inner perimeter of the chamber is preferably substantially the same as the outer perimeter of the consumable in its chamber-pressed state, or it can be the inner perimeter of a plane orthogonal to the length direction of the chamber. Furthermore, "the outer perimeter of the consumable before being contained in the chamber" can be the portion of the outer perimeter of the consumable before being contained in the chamber that, when contained in the chamber, is positioned in the length direction of the chamber corresponding to the inner perimeter of the compared chamber. Additionally, "the outer perimeter of the consumable in its chamber-pressed state" can be the portion of the outer perimeter of the consumable in its chamber-pressed state that, in the length direction of the chamber, is positioned corresponding to the inner perimeter of the compared chamber.

[0065] Furthermore, in the second method, features from other methods can be combined or applied as long as they do not impair the function or effect of the second method. Additionally, the chamber in the second method can also have a retaining part as in other methods.

[0066] According to a third aspect of the present invention, a smoking system is provided, comprising a consumable having a smokeable substance and a device for heating the smokeable substance to atomize it. The device includes a chamber for receiving the consumable. The chamber includes an opening for inserting the consumable and a holding portion for holding the consumable. The holding portion includes a pressing portion for pressing a portion of the consumable. The device includes an induction coil for heating at least the pressing portion. The pressing portion includes a base heated by the induction coil.

[0067] According to the third method, since the consumable is pressed by the heated surface (the inner surface of the pressing part), and the pressing part of the consumable is heated by the induction coil, heat from the pressing part can be efficiently transferred to the consumable. The base can also be disposed on or cover the outer or inner surface of the pressing part, or it can be contained in the wall of the chamber constituting the pressing part, and the wall of the chamber constituting the pressing part can also be formed by the base.

[0068] While the induction coil can be composed of a single wire, it can also be a spiral-shaped stranded wire for efficient heat generation. The single wire or stranded wire is preferably made of at least one material selected from the group consisting of alloys such as copper, aluminum, nickel, silver, gold, and their stainless steels. The sheath material of the stranded wire can be, for example, polyimide or polyester.

[0069] The induction coil can also be wound into a helical (three-dimensional spiral) or a spiral (two-dimensional vortex) shape. The shape of the induction coil can also be cylindrical (formed by bending a helical or spiral coil) or planar. The induction coil can be adjacent to the cavity, surround the cavity, or protrude into the cavity; however, by configuring it to surround the cavity, energy can be efficiently supplied to the pressing part of the cavity. There can be one or multiple induction coils. As an example of a cavity-surrounding configuration, the induction coil can be configured as a helical shape surrounding the cavity, or it can be configured by bending a spiral coil to surround the cavity, or it can have multiple planar coils surrounding the cavity. However, by configuring it as a helical shape surrounding the cavity, a simple structure can be achieved, reducing manufacturing costs.

[0070] The frequency applied to the induction coil can be from about 80 kHz to 500 kHz, preferably from about 150 kHz to 250 kHz, and more preferably from 190 kHz to 210 kHz. Alternatively, the frequency applied to the induction coil can be from 1 MHz to 30 MHz, preferably from 2 MHz to 10 MHz, and even more preferably from 5 MHz to 7 MHz. These frequencies can also be determined taking into account the material, shape, and other properties of the base.

[0071] The device can also be configured to operate under varying electromagnetic fields with a magnetic flux density of up to about 0.5 Tesla (T) and down to 2.0 Tesla (T).

[0072] In this specification, the term "base" refers to a material capable of converting electromagnetic energy into heat, specifically a material intended for heating a "smokeable substance." The base is positioned to transfer heat to the "smokeable substance." When the base is located within a fluctuating electromagnetic field, the eddy currents induced within the base and the hysteresis losses within the base contribute to its heating.

[0073] The base is preferably made of at least one material selected from the group consisting of aluminum, iron, nickel, and their alloys (e.g., nickel-chromium alloys, stainless steel). The base and the current path flowing through it are preferably annular, comprising a space surrounding the consumable. This allows for the efficient generation of eddy currents in the heating portion of the chamber.

[0074] The shape of the base is arbitrary; for example, it can be granular, rod-shaped, strip-shaped, ring-shaped, or cylindrical. If the base has a ring-shaped current path, eddy currents can be generated efficiently. Multiple bases of the same shape can also be configured, as can bases of different shapes.

[0075] Furthermore, in the third approach, features of other approaches can be combined or applied as long as they do not impede the function or effect of the third approach.

[0076] According to a fourth aspect of the present invention, a device is provided for heating a smokeable substance to atomize it. The device includes a chamber for receiving a consumable and a heating portion for heating the consumable received in the chamber. The chamber includes an opening for inserting the consumable and a holding portion for holding the consumable. The holding portion includes a pressing portion for pressing a portion of the consumable and a non-pressing portion. The pressing portion and the non-pressing portion each have an inner surface and an outer surface. The heating portion is disposed on the outer surface of the pressing portion.

[0077] According to the fourth method, since the consumable is in close contact with the heating surface (the inner surface of the pressing part), the heat from the heating part can be efficiently transferred to the consumable.

[0078] As described above, placing the heating element on the outer surface of the pressing part is merely one example of a configuration that efficiently transfers heat to the consumable through the chamber by substantially pressing the consumable against the heating surface of the chamber. A fourth approach may also provide a device for heating a smokeable substance to atomize it. The device includes a chamber for housing the consumable and a heating element for heating the consumable housed within the chamber. The chamber includes an opening for inserting the consumable and a holding part for holding the consumable. The holding part includes a pressing part for pressing a portion of the consumable and a non-pressing part, each having an inner surface and an outer surface, respectively. The consumable is heated via the pressing part. Furthermore, while the heating element is not particularly limited, it may be a heating element disposed on the outer surface of the pressing part as described above, or it may include a base and be heated using an electromagnetic field and / or magnetic lines of force generated by an induction coil, as described above.

[0079] The heating element is preferably disposed on the outer surface of the pressing part without any gaps. "Without gaps" here also means substantially without gaps. This ensures that the consumable and the heating surface (the inner surface of the pressing part) are in substantial contact, thus enabling more efficient heat transfer from the heating element to the consumable. Alternatively, the heating element may include an adhesive layer. In this case, it is preferable that the heating element including the adhesive layer is disposed on the outer surface of the pressing part without any gaps.

[0080] Preferably, the inner surface of the pressing part has a pair of opposing planar pressing surfaces, and the inner surface of the non-pressing part has a pair of opposing curved non-pressing surfaces connecting the two ends of the pair of planar pressing surfaces. More preferably, the pressing part and the non-pressing part have uniform (including substantially uniform) and identical (including substantially identical) thicknesses. This simplifies the chamber structure, facilitates high-precision manufacturing, allows for a well-balanced configuration of the pressing and non-pressing parts, homogenizes heating, and facilitates the precise and gapless placement of the heating element on the outer surface of the pressing part, thereby improving heating efficiency.

[0081] Furthermore, in the fourth method, features of other methods can be combined or applied as long as they do not hinder the function or effect of the fourth method.

[0082] According to a fifth aspect of the invention, a consumable for use in any of the above-described smoking systems is provided. The consumable has a first portion partially pressed by a pressing part of a chamber, an inhalation port, and a second portion located between the first portion and the inhalation port.

[0083] Furthermore, in the fifth method, features of other methods can be combined or applied as long as they do not hinder the function or effect of the fifth method.

[0084] According to a sixth aspect of the present invention, a device is provided for heating and atomizing a smokeable substance disposed on a consumable. The device includes a chamber for receiving the consumable. The chamber includes an opening for inserting the consumable and a holding portion for holding the consumable. The holding portion includes a pressing portion for pressing a portion of the consumable. The device includes an induction coil for heating at least the pressing portion. The pressing portion includes a base heated by the induction coil.

[0085] Furthermore, in the sixth method, features of other methods can be combined or applied as long as they do not impede the function or effect of the sixth method.

[0086] According to a seventh aspect of the present invention, a device is provided for heating a smokeable substance to atomize it. The device includes a chamber for receiving a consumable, a heating part for heating the consumable received in the chamber, and a cylindrical sleeve surrounding the chamber. The chamber includes an opening for inserting the consumable and a holding part for holding the consumable. The holding part includes a pressing part for pressing a portion of the consumable and a non-pressing part. The pressing part and the non-pressing part each have an inner surface and an outer surface. The holding part is provided with a gap that, when the consumable is positioned at a desired position in the chamber, communicates between the inner surface of the non-pressing part and the consumable through the opening of the chamber and the end face of the consumable positioned at the desired position in the chamber, or the opening of the chamber and the end face of the consumable positioned in the chamber and located away from the opening of the chamber. In a direction orthogonal to the length direction of the chamber, when the shortest distance between the inner surface of the sleeve and the outer surface of the pressing part is defined as L1, and the shortest distance between the inner surface of the sleeve and the outer surface of the non-pressing part of the chamber is defined as L2, L1 is greater than L2.

[0087] According to the seventh method, the distance between the outer surface of the pressing part of the pressable consumable and the inner surface of the sleeve is longer than that of the non-pressable part, thus increasing the length of the air layer in the gap. As a result, when the pressable part heats the consumable, the heat insulation efficiency based on the air layer between the pressable part and the sleeve can be improved. The sleeve preferably includes a heat insulation portion. In this case, since the chamber is surrounded by the heat insulation portion, heat transfer from the heated consumable to the outside of the device can be suppressed.

[0088] Furthermore, in the seventh method, features of other methods can be combined or applied as long as they do not impede the function or effect of the seventh method.

[0089] According to an eighth aspect of the present invention, a device is provided. The device includes a chamber for receiving a consumable and a heating portion for heating the consumable received in the chamber. The chamber includes an opening for inserting the consumable and a holding portion for holding the consumable. The holding portion includes a pressing portion for pressing a portion of the consumable and a non-pressing portion. The pressing portion and the non-pressing portion each have an inner surface and an outer surface. The inner circumferential length of the holding portion is the same as the outer circumferential length of the consumable before being pressed by the pressing portion or the outer circumferential length of the consumable in the state of being pressed by the pressing portion.

[0090] When the inner circumference of the holding part is substantially the same as the outer circumference of the consumable, a portion of the consumable is pressed by the pressing part, making the outer circumference shape of the consumable approximately the same as the cross-sectional shape of the inner surface of the holding part. Compared to the case where the inner circumference length and shape of the holding part are the same as the outer circumference length and shape of the consumable, this smoking system forms a portion of the consumable that is pressed by the pressing part, thus improving the heat transfer efficiency from the heating part to the consumable. Furthermore, compared to the case where the outer circumference length of the consumable is shorter than the inner circumference length of the holding part, the unpressed portion of the outer circumference surface of the consumable is also substantially in contact with the inner circumference surface (non-pressed surface) of the holding part, thus improving the heat transfer efficiency from the heating part to the consumable. Moreover, compared to the case where the outer circumference length of the consumable is longer than the inner circumference length of the holding part, the consumable can be smoothly inserted into the holding part, suppressing density strain on the outer circumference surface and inside the consumable (e.g., tobacco, as an example of a smokeable substance). As a result, uneven heating caused by density strain inside the consumable and deviations in the airflow resistance of each consumable can be suppressed.

[0091] Furthermore, in the eighth method, features of other methods can be combined or applied as long as they do not impede the function or effect of the eighth method.

[0092] According to a ninth aspect of the present invention, a smoking system is provided, comprising a consumable having a smokeable substance and a device for heating the smokeable substance to atomize it. The device includes a chamber for receiving the consumable and a heating portion for heating the consumable received in the chamber. The chamber includes an opening for inserting the consumable and a holding portion for holding the consumable. The holding portion includes a pressing portion for pressing a portion of the consumable and a non-pressing portion. The pressing portion and the non-pressing portion each have an inner surface and an outer surface. The inner circumference length of the holding portion is the same as the outer circumference length of the consumable before or after being pressed by the pressing portion.

[0093] When the inner circumference of the holding part is substantially the same as the outer circumference of the consumable, a portion of the consumable is pressed by the pressing part, making the outer circumference shape of the consumable approximately the same as the cross-sectional shape of the inner surface of the holding part. Compared to the case where the inner circumference length and shape of the holding part are the same as the outer circumference length and shape of the consumable, this smoking system forms a portion of the consumable that is pressed by the pressing part, thus improving the heat transfer efficiency from the heating part to the consumable. Furthermore, compared to the case where the outer circumference length of the consumable is shorter than the inner circumference length of the holding part, the unpressed portion of the outer circumference surface of the consumable is also substantially in contact with the inner circumference surface (non-pressed surface) of the holding part, thus improving the heat transfer efficiency from the heating part to the consumable. Moreover, compared to the case where the outer circumference length of the consumable is longer than the inner circumference length of the holding part, the consumable can be smoothly inserted into the holding part, suppressing density strain on the outer circumference surface and inside the consumable (e.g., tobacco, as an example of a smokeable substance). As a result, uneven heating caused by density strain inside the consumable and deviations in the airflow resistance of each consumable can be suppressed.

[0094] Furthermore, in the ninth method, features of other methods can be combined or applied as long as they do not impede the function or effect of the ninth method.

[0095] According to a tenth aspect of the present invention, a smoking system is provided, comprising a consumable having a smokeable substance and a device for heating the smokeable substance to atomize it. The device includes a chamber for receiving the consumable and a heating portion for heating the consumable received in the chamber. The chamber includes an opening for inserting the consumable and a holding portion for holding the consumable. The holding portion includes a pressing portion for pressing a portion of the consumable and a non-pressing portion. The pressing portion and the non-pressing portion each have an inner surface and an outer surface. The consumable includes a first portion having a first hardness and a second portion having a second hardness, the second portion being a portion different from the first portion in the insertion direction of the consumable. When the consumable is positioned in a desired position in the chamber, the consumable is positioned such that at least a portion of the first portion is pressed against the inner surface of the pressing portion, and simultaneously positioned such that at least a portion of the second portion is pressed against the inner surface of the pressing portion.

[0096] According to the tenth method, when the first part contains a smoke-producing substance, it is possible to simultaneously achieve efficient heating of the smoke-producing substance based on the pressing part and secure retention of the consumable. Furthermore, in the tenth method, features of other methods can be combined or applied as long as they do not impair the function or effect of the tenth method.

[0097] According to an eleventh aspect of the present invention, a device is provided for heating a smokeable substance to atomize it. The device includes a chamber for receiving a consumable and a heating portion for heating the consumable received in the chamber. The chamber includes a holding portion for holding the consumable. The holding portion includes a pressing portion for pressing a portion of the consumable. The pressing portion has an inner surface and an outer surface. The heating portion is disposed on the outer surface of the pressing portion. The outer surface of the pressing portion is planar.

[0098] According to the eleventh method, since the consumable and the heating surface (the inner surface of the pressing part) are substantially in close contact, heat from the heating part can be efficiently transferred to the consumable. Furthermore, by making the outer surface of the pressing part flat, when a strip electrode is connected to the heating part disposed on the outer surface of the pressing part, deflection of the strip electrode can be suppressed, thus facilitating the winding of the electrode within the device. Additionally, compared to cases where the outer surface of the pressing part is curved or uneven, the heating part can be positioned with high precision, and the heating part can be easily disposed on the outer surface of the pressing part without gaps.

[0099] Furthermore, in the eleventh method, features of other methods can be combined or applied as long as they do not impede the function or effect of the eleventh method. Attached Figure Description

[0129] <First Implementation>

[0130] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings described below, the same or equivalent constituent elements are labeled with the same reference numerals and repeated descriptions are omitted. Figure 1 This is a diagram illustrating the smoking system 100 according to the first embodiment. (See diagram below.) Figure 1 As shown, the smoking system 100 includes: a consumable 110 containing a smokeable substance; and a device 120 for heating the smokeable substance to atomize it. In the first embodiment, an example is shown where a user performs a smoking action while holding the consumable 110 in their mouth. The air inhaled by the user is introduced into the user's mouth, for example, in the order of airflow 100A, airflow 100C, and airflow 100B.

[0131] Consumable 110 is a substrate containing a smokeable substance such as tobacco that can produce a smokeable aroma, and has, for example, a columnar shape extending along its length. Consumable 110 may be, for example, a tobacco stick.

[0132] Device 120 includes a battery 10, a control circuit 20, and a heater assembly 30. The battery 10 stores the electricity used in device 120. For example, battery 10 is a lithium-ion battery. Battery 10 may also be rechargeable by an external power source.

[0133] The control circuit 20, consisting of a CPU and memory, controls the operation of the device 120. For example, the control circuit 20 starts heating the consumable 110 based on user input from an input device such as a button or slide switch (not shown), and stops heating the consumable 110 after a certain period of time. If the number of times the user smokes exceeds a certain value, the control circuit 20 can stop heating the consumable 110 even before a certain period of time has elapsed since heating began. For example, the smoking action is detected by a sensor (not shown).

[0134] Alternatively, the control circuit 20 may start heating the consumable 110 upon the start of the smoking action and stop heating the consumable 110 upon the end of the smoking action. The control circuit 20 may also stop heating the consumable 110 even before the smoking action ends, provided a certain time has elapsed since the start of the smoking action. In this embodiment, the control circuit 20 is positioned between the battery 10 and the heater assembly 30 to suppress heat transfer from the heater assembly 30 to the battery 10.

[0135] The heater assembly 30 is the assembly that heats the consumable 110. Figure 2 Show Figure 1 A perspective view of the heater assembly 30 shown. Figure 2 As shown, the heater assembly 30 has a top cap 32, a heating element 40, and a chamber 50. The chamber 50 is configured to accommodate a consumable 110. The heating element 40 is configured to heat the consumable 110 accommodated in the chamber 50. The top cap 32 may also be configured to function as a guide when the consumable 110 is inserted into the chamber 50, and to fix the chamber 50 relative to the device 120.

[0136] Figure 3 A three-dimensional view of chamber 50 is shown. Figure 4 Show Figure 3 The cross-sectional view of chamber 50 shown in view 4-4. Figure 5A Show Figure 4 The diagram shows a cross-sectional view of chamber 50 in view 5A-5A. Figure 5B Show Figure 4 The diagram shows a cross-sectional view of chamber 50 in view 5B-5B. Figure 5C Show Figure 4 The diagram shows a cross-sectional view of chamber 50 in view 5C-5C. (See diagram below.) Figure 3 as well as Figure 4 As shown, the chamber 50 can be a bottomed cylindrical component including an opening 52 for inserting the consumable 110 and a holding portion 60 for holding the consumable 110. Alternatively, the chamber 50 can also be a bottomless cylindrical body. The chamber 50 is preferably made of a metal with high thermal conductivity, such as stainless steel. This allows for effective heating of the consumable 110 from the chamber 50.

[0137] like Figure 4 as well as Figure 5C As shown, the retaining part 60 includes a pressing part 62 and a non-pressing part 66 that are part of the pressable consumable 110. The pressing part 62 has an inner surface 62a and an outer surface 62b. The non-pressing part 66 has an inner surface 66a and an outer surface 66b. Figure 2 As shown, the heating element 40 is disposed on the outer surface 62b of the pressing element 62. Preferably, the heating element 40 is disposed on the outer surface 62b of the pressing element 62 without gaps. Alternatively, the heating element 40 may include an adhesive layer. In this case, the heating element 40 including the adhesive layer is preferably disposed on the outer surface 62b of the pressing element 62 without gaps.

[0138] The opening 52 of the chamber 50 is preferably designed to accommodate the consumable 110 without pressing it. The shape of the opening 52 of the chamber 50, which is on a plane orthogonal to the length direction of the chamber 50, in other words, the direction in which the consumable 110 is inserted into the chamber 50, or the direction in which the entire side of the chamber 50 extends, can also be polygonal or elliptical, but is preferably circular.

[0139] like Figure 3 as well as Figure 5C As shown, the outer surface 62b of the pressing part 62 is a plane. By making the outer surface 62b of the pressing part 62 a plane, as... Figure 2 As shown, when the strip electrode 48 is connected to the heating portion 40 disposed on the outer surface 62b of the pressing portion 62, deflection of the strip electrode 48 can be suppressed. As a result, winding of the electrode 48 within the device 120 becomes easier. Furthermore, compared to the case where the outer surface 62b of the pressing portion 62 is curved or uneven, the heating portion 40 can be positioned with high precision, and the heating portion 40 can be easily disposed without gaps on the outer surface 62b of the pressing portion 62. Figure 4 as well as Figure 5C As shown, the inner surface 62a of the pressing part 62 is a plane. Furthermore, as... Figure 4 as well as Figure 5C As shown, the thickness of the pressing part 62 is uniform.

[0140] like Figure 3 , Figure 4 as well as Figure 5C As shown, in the first embodiment, the chamber 50 has two or more pressing portions 62 in the circumferential direction of the chamber 50. For example... Figure 4 as well as Figure 5C As shown, the two pressing portions 62 of the holding portion 60 are positioned opposite each other. Preferably, the distance between at least a portion of the inner surfaces 62a of the two pressing portions 62 is smaller than the width of the portion of the consumable 110 inserted into the chamber 50 positioned between the pressing portions 62. As shown, the inner surface 62a of the pressing portion 62 is planar.

[0141] like Figure 5C As shown, the inner surface 62a of the pressing part 62 has a pair of opposing planar pressing surfaces, and the inner surface 66a of the non-pressing part 66 has a pair of opposing curved non-pressing surfaces connecting the two ends of the pair of planar pressing surfaces. As shown, the curved non-pressing surfaces can have an overall arc-shaped cross-section on a plane orthogonal to the length direction of the chamber 50. Figure 5C As shown, the retaining part 60 is composed of a metal cylindrical body with a uniform thickness.

[0142] Figure 6A This is a longitudinal cross-sectional view of the chamber 50, including the non-pressing part 66, with the consumable 110 positioned in the desired location in the chamber 50. Figure 6B This is a longitudinal cross-sectional view of the chamber 50, including the pressing part 62, with the consumable 110 positioned in the desired location in the chamber 50. Figure 7A yes Figure 6B The cross-sectional view of chamber 50 shown in view 7A-7A is shown. Figure 7B yes Figure 6B The diagram shows a cross-sectional view of chamber 50 in view of 7B-7B. Additionally, in... Figure 7B In order to make it easier to understand the pressing of the consumable 110 in the pressing part 62, a cross-section of the consumable 110 in the state before pressing is shown.

[0143] Figure 7B The gap 67 between the inner surface 66a of the non-pressing part 66 and the consumable 110 is substantially maintained even when the consumable 110 is positioned in the desired position in the chamber 50 and deformed by being pressed by the pressing part 62. This gap 67 can accommodate the opening 52 of the chamber 50 and the end face of the consumable 110 positioned within the chamber 50. Figure 6A as well as Figure 6B The lower end face of the consumable 110 can also communicate with the opening 52 of the chamber 50 and the end face of the consumable 110 located within the chamber 50 and away from the opening 52 of the chamber 50. Figure 6A as well as Figure 6B The lower end face is connected. Therefore, there is no need to separately provide a flow path for introducing air supplied to the consumable 110 in the smoking system 100, thus simplifying the structure of the smoking system 100. Furthermore, since a portion of the forming gap 67 of the non-pressable part 66 is exposed, the flow path can be easily cleaned. From the viewpoint of airflow resistance, the height of the gap 67 between the inner surface 66a of the non-pressable part 66 and the consumable 110 is preferably 0.1 mm to 1.0 mm and more preferably 0.2 mm to 0.8 mm and most preferably 0.3 mm to 0.5 mm.

[0144] like Figure 3 As shown in Figure 6, chamber 50 has a bottom 56. The bottom 56 is as follows... Figure 6B As shown, a portion of the consumable 110 inserted into the chamber 50 is supported in such a way that at least a portion of the end face of the consumable 110 is exposed. Additionally, the bottom 56 can support a portion of the consumable 110 in such a way that the exposed end face of the consumable 110 communicates with the gap 67.

[0145] like Figure 4 , Figure 6A as well as Figure 6B As shown, the bottom 56 of chamber 50 has a bottom wall 56a, and may also have side walls 56b. The width of the bottom 56, divided by the side walls 56b, may decrease towards the bottom wall 56a. Figure 5C as well as Figure 7B As shown, the inner surface 66a of the non-pressing portion 66 of the holding portion 60 is curved on a plane orthogonal to the length direction of the chamber 50.

[0146] The shape of the inner surface 66a of the non-pressable portion 66 on the plane orthogonal to the length direction of the chamber 50 is preferably the same as the shape of the opening 52 on the plane orthogonal to the length direction of the chamber 50 at any position in the length direction of the chamber 50. In other words, the inner surface 66a of the non-pressable portion 66 is preferably formed by extending the inner surface of the chamber 50 that forms the opening 52 along the length direction.

[0147] like Figures 2 to 4 As shown, the chamber 50 preferably has a cylindrical non-holding portion 54 between the opening 52 and the holding portion 60. When the consumable 110 is positioned in the desired position in the chamber 50, a gap can be formed between the non-holding portion 54 and the consumable 110.

[0148] like Figure 4 As shown in Figure 7, the outer peripheral surface of the retaining part 60 preferably has the same shape and size along the entire length of the retaining part 60 (the outer peripheral length of the retaining part 60 on the surface orthogonal to the length direction of the retaining part 60).

[0149] In addition, such as Figure 3 , Figure 4 , Figure 5B as well as Figure 6B As shown, the chamber 50 preferably has a first guide portion 58, which has a conical surface 58a that connects the inner surface of the chamber 50 forming the opening 52 with the inner surface 62a of the pressing portion 62.

[0150] like Figure 2 As shown, the heating section 40 has a heating element 42. The heating element 42 may, for example, be a heating rail. Figure 5CAs shown, the outer surface 62b of the pressing part 62 and the outer surface 66b of the non-pressing part 66 are connected to each other at an angle, and a boundary 71 can be formed between the outer surface 62b of the pressing part 62 and the outer surface 66b of the non-pressing part 66. The heating track preferably extends in a direction intersecting the direction of the boundary 71 (the length direction of the chamber), and more preferably extends in a direction perpendicular to the direction of the boundary 71.

[0151] like Figure 2 As shown, the heating part 40 preferably has an electrically insulating member 44 that covers at least one side of the heating element 42, in addition to the heating element 42. In this embodiment, the electrically insulating member 44 is arranged to cover both sides of the heating element. Furthermore, the electrically insulating member 44 is preferably disposed in a region of the outer surface of the holding part 60. In other words, the electrically insulating member 44 is preferably configured so that it does not protrude from the outer surface of the holding part 60 on the side of the first guide portion 58 in the longitudinal direction of the chamber 50. As described above, the first guide portion 58 is provided between the opening 52 and the pressing part 62, so the shape of the outer surface of the chamber 50 and the outer perimeter of the chamber on the plane orthogonal to the longitudinal direction of the chamber 50 can be changed in the longitudinal direction of the chamber 50. Therefore, by disposing the electrically insulating member 44 on the outer surface of the holding part 60, relaxation can be suppressed.

[0152] The device 120 preferably further comprises a sheet covering the chamber 50 and the heating part 40 and fixing the heating part 40 to the outer surface of the chamber 50. This allows the heating part 40 to be securely fixed to the outer surface of the chamber 50, thereby further improving heating efficiency and stabilizing the structure around the chamber 50. Furthermore, the sheet is preferably disposed on the outer surface of the holding part 60. In other words, the sheet is preferably disposed such that it does not protrude from the outer surface of the holding part 60 on the side of the first guide portion 58 in the longitudinal direction of the chamber 50. As described above, the first guide portion 58 is provided between the opening 52 and the holding part 60, thus allowing the shape of the outer surface of the chamber 50 and the outer perimeter length of the chamber on the plane orthogonal to the longitudinal direction of the chamber to be changed in the longitudinal direction of the chamber 50. Therefore, by disposing the sheet on the outer surface of the holding part 60, relaxation can be suppressed.

[0153] The heating element 40 is preferably not disposed on at least one of the outer surfaces of the chamber 50 selected between the opening 52 and the first guide 58, i.e., the outer surface of the non-holding part 54, the outer surface of the first guide 58, and the outer surface of the non-pressing part 66. The heating element 40 is preferably disposed integrally over the outer surface 62b of the pressing part 62.

[0154] In the first embodiment, such as Figure 2As shown, the device 120 has a strip-shaped electrode 48 extending from the heating portion 40. Preferably, the strip-shaped electrode 48 extends from the outer surface 62b of the pressing portion 62, which is planar, to the outside of the outer surface 62b of the pressing portion 62, with the heating portion 40 disposed thereon. Figure 2 As shown, the strip electrode 48 extends from the outer surface 62b of each of the two pressing portions 62. However, this is not a limitation; the strip electrode 48 may also extend from only one outer surface 62b of the two pressing portions 62. Additionally, as... Figure 2 As shown, the strip electrode 48 extends to the side opposite to the opening 52 of the chamber. The strip electrode 48 may have a structure in which a layer of conductive tracks is disposed between layers of a double-layered electrically insulating material.

[0155] In addition, such as Figure 2 , Figure 6A as well as Figure 6B As shown, the heating section 40 has a first portion 40a located on the side opposite to the opening 52 and a second portion 40b located on the side of the opening 52. Preferably, the heater power density of the second portion 40b is higher than that of the first portion 40a. Alternatively, the heating rate of the second portion 40b is preferably higher than that of the first portion 40a. Alternatively, the heating temperature of the second portion 40b is preferably higher than that of the first portion 40a in any given equal time interval. Preferably, the second portion 40b covers the outer surface of the holding portion 60 corresponding to at least half of the smokeable substance contained in the consumable 110 along its length direction when the consumable 110 is positioned in the desired location in the chamber 50.

[0156] In the embodiments described above, the chamber 50 has a pair of pressing parts 62 facing each other, but the shape of the chamber is not limited thereto. Figures 8 to 11 This is a schematic cross-sectional view showing another example of the pressing part 62 of the chamber 50. Figures 8 to 11 In the diagram, to facilitate understanding of pressing the consumable 110 in the pressing section 62, a dashed line represents the cross-section of the consumable 110 in its state before pressing. Figure 8 In the example shown, chamber 50 includes three pressing portions 62 with planar inner surfaces 62a and one non-pressing portion 66 (inner surface 66a). One pair of pressing portions 62 (inner surfaces 62a) are opposite each other. The remaining pressing portions 62 and non-pressing portions 66 are respectively disposed between the pairs of pressing portions 62 and are opposite each other. Figure 8 As shown, the distance between a pair of pressing portions 62 having a planar inner surface 62a is smaller than the diameter of the inserted consumable 110 having a circular cross-section. As a result, when the consumable 110 is disposed in the chamber 50, it is pressed by the inner surface 62a of the pressing portion 62.

[0157] exist Figure 9 In the example shown, chamber 50 has three pressing portions 62 (inner surface 62a) and three non-pressing portions 66 (inner surface 66a) respectively disposed between the three pressing portions 62. The inner surface 62a of the pressing portions 62 is planar, and the inner surface 66a of the non-pressing portions 66 is curved. Each pressing portion 62 and each non-pressing portion 66 are opposite each other. Figure 9 The point P1 where the lines extending perpendicularly from the center C1 of the inner surface 62a of each pressing part 62 intersect in the cross-section shown, i.e., on the plane orthogonal to the length direction of the chamber, is smaller than the radius of the inserted consumable 110 with a circular cross-section. Therefore, when the consumable 110 is placed inside the chamber 50, it is pressed by the pressing part 62.

[0158] exist Figure 10 In the example shown, chamber 50 has a pressing part 62 (inner surface 62a) and a non-pressing part 66 (inner surface 66a). The inner surface 62a of the pressing part 62 is flat, and the inner surface 66a of the non-pressing part 66 is curved. The pressing part 62 and the non-pressing part 66 form a cylindrical holding part 60.

[0159] exist Figure 11 In the example shown, the chamber 50 has four pressing portions 62 (inner surfaces 62a) and four non-pressing portions 66 (inner surfaces 66a). The inner surfaces 62a of the pressing portions 62 are planar, and the inner surfaces 66a of the non-pressing portions 66 are curved to connect the inner surfaces 62a of adjacent pressing portions 62. Two pressing portions 62 (inner surfaces 62a) are opposite each other, and the remaining two pressing portions 62 (inner surfaces 62a) are opposite each other. At least one of the distance between the pair of opposing pressing portions 62 (inner surfaces 62a) and the distance between the other pair of opposing pressing portions 62 (inner surfaces 62a) is smaller than the diameter of the consumable 110. Thus, when the consumable 110 is disposed in the chamber 50, it is pressed by the pressing portions 62.

[0160] The above, such as Figures 8 to 11 As shown, there may be only one pressing part 62, or there may be three or more in the circumferential direction of the chamber 50. Furthermore, each pressing part 62 may be configured to face another pressing part 62, or it may be configured to face another non-pressing part 66. Additionally, as... Figure 8 , Figure 10 As shown in the example, when the pressure received by the press part 62 on the consumable 110 in a plane orthogonal to the length direction of the chamber is biased in a certain direction (in... Figure 8 In the middle, consumable 110 is subjected to pressure from the bottom direction of the attached drawing towards the top direction of the attached drawing. Figure 10In the figure, the consumable 110 is subjected to pressure from the top direction to the bottom direction. To prevent the consumable 110 from moving and contacting the inner surface 66a of the non-pressing part 66, a support member may be provided between the consumable 110 and the device 120. The support member may be located at a position corresponding to the smoke-absorbing material of the consumable 110, or it may be located at a different position. Furthermore, Figures 8 to 11 The image shows the consumable 110 in its state before being pressed. However, even when a gap 67 is formed between the non-pressed portion 66 and the consumable 110, the gap 67 is substantially maintained between the inner surface 66a of the non-pressed portion 66 and the consumable 110, even if the consumable 110 is deformed by being pressed by the pressing portion 62. Alternatively, as in the fourth embodiment described later, the consumable 110 may be deformed by being pressed by the pressing portion 62, and the inner surface 66a of the non-pressed portion 66 may come into contact with the consumable 110.

[0161] Next, the consumables 110 used in the smoking system 100 will be described in detail. Figure 12 This is a rough side cross-sectional view of consumable item 110. Figure 2 In the illustrated embodiment, the consumable 110 includes a smokeable substance 111, a cylindrical component 114, a hollow filter tip 116, and a filter tip 115. The smokeable substance 111 is rolled from a first roll of paper 112. The cylindrical component 114, the hollow filter tip 116, and the filter tip 115 are rolled from a second roll of paper 113, which is different from the first roll of paper 112. The second roll of paper 113 also rolls a portion of the first roll of paper 112 containing the smokeable substance 111. Thus, the cylindrical component 114, the hollow filter tip 116, and the filter tip 115 are connected to the smokeable substance 111. However, the second roll of paper 113 may be omitted, and the first roll of paper 112 may be used to connect the cylindrical component 114, the hollow filter tip 116, and the filter tip 115 to the smokeable substance 111. The outer surface near the end of the filter tip 115 side of the second roll of paper 113 is coated with a lip release agent 117 to prevent the user's lips from sticking tightly to the second roll of paper 113. The portion of the consumable 110 coated with the lip release agent 117 functions as the suction port of the consumable 110.

[0162] In this embodiment, the portion corresponding to the portion of the smokeable material 111 and the portion of the first roll of paper 112 is referred to as the first portion S1. Furthermore, at least a portion of the portion corresponding to the tubular member 114 is referred to as the second portion S2. More specifically, the portion of the tubular member 114 wound onto the second roll of paper 113 that is not coated with the lip release agent 117 is referred to as the second portion S2.

[0163] The first part S1 has a smokeable substance 111, such as tobacco. Additionally, in the first part S1, the first roll of paper 112 wound around the smokeable substance 111 can be a breathable sheet component. A cap to prevent the smokeable substance 111 from falling off may also be provided at the end of the first part S1. This cap can be, for example, adhered to the first roll of paper 112 with glue. Alternatively, the cap can be fixed to the first roll of paper 112 by friction. The cap can be, for example, filter paper or an acetate filter. The cylindrical component 114 provided in the second part S2 can be a paper tube or a hollow filter.

[0164] In the illustrated example, the consumable 110 includes a smoking element 111, a cylindrical component 114, a hollow filter tip 116, and a filter tip 115, but the configuration of the consumable 110 is not limited to this. For example, the hollow filter tip 116 may be omitted, and the cylindrical component 114 and the filter tip 115 may be arranged adjacent to each other.

[0165] As shown in the figure, the first portion S1 of the consumable 110 is disposed at the end side of the consumable 110 along its length direction, which is closer to the second portion S2. The first portion S1 has a first hardness, and the second portion S2 has a second hardness. The first hardness is preferably 65% ​​or more and 90% or less, more preferably 70% or more and 85% or less, and most preferably 73% or more and 82% or less.

[0166] When the consumable 110 is inserted into the chamber 50, the consumable 110 is positioned such that at least a portion of the second portion S2 is pressed against the inner surface 62a of the pressing portion 62. The second hardness is preferably 90% or more and 99% or less, more preferably 90% or more and 98% or less, and most preferably 92% or more and 96% or less. This facilitates insertion, and the consumable 110 is securely held in the holding portion 60.

[0167] The second hardness is preferably higher than the first hardness. Accordingly, both ease of insertion of the consumable 110 into the holding portion 60 and secure retention of the consumable 110 can be achieved simultaneously. Furthermore, when the consumable 110 is inserted into the chamber 50, the state changes from only the first portion S1 being pressed against the inner surface 62a of the pressing portion 62 to a state where the second portion S2 is also pressed against the inner surface 62a of the pressing portion 62. As a result, the user can feel the change in resistance during the insertion of the consumable 110. Consequently, the user can discern the extent to which the consumable 110 is inserted into the chamber 50 during insertion, providing a clue as to how much further to insert it before reaching the desired insertion position, making it easier to position the consumable 110 at the desired location. Figure 12 As shown, when the first part S1 and the second part S2 are arranged adjacent to each other, the change in resistance can be felt more clearly.

[0168] As stated above, the term "hardness" as used throughout this specification refers to the resistance to deformation. Hardness is generally expressed as a proportion. Figure 13 The figure shows cross-sections of the consumable 110 before and after applying load F. As shown, the diameter of the consumable before applying load F is set as D. s The diameter of the direction in which the load is applied to the consumable 110 under a specified load is set as D. d The deformation d of the consumable under a specified load can be determined by D. s -D d The hardness (%) is expressed as Dd / Ds×100 (%).

[0169] The length of the first portion S1 of the consumable 110 in the longitudinal direction is less than or equal to the length of the inner surface 62a of the pressing portion 62 in the longitudinal direction. When the consumable 110 is inserted into the chamber 50, it is preferable to position the consumable 110 in the chamber 50 in such a way that the first portion S1 of the consumable 110 does not protrude from the inner surface 62a of the pressing portion 62 in the longitudinal direction of the chamber 50. Furthermore, when the consumable 110 is positioned in the desired position in the chamber 50, it is preferable that the entire outer peripheral surface of the smokeable portion of the consumable 110 is covered by the retaining portion 60.

[0170] When the consumable 110 is positioned in the desired location within the chamber 50, the distance by which the second part S2 of the consumable 110 is inserted into the retaining part 60 is preferably 1.0 mm or more and 10.0 mm or less, more preferably 2.0 mm or more and 8.0 mm or less, and most preferably 4.0 mm or more and 6.0 mm or less.

[0171] The length from the bottom wall 56a of the chamber 50 to the end of the pressing part 62 at the opening 52 side is preferably longer than the length of the first part S1 of the consumable 110 in the longitudinal direction (hereinafter referred to as the length of the first part), and shorter than 1.5 times the length of the first part S1, more preferably shorter than 1.35 times. Furthermore, at least a portion of the first part S1 of the consumable 110 is preferably located closer to the opening 52 side than the center of the holding part 60 in the longitudinal direction when the consumable 110 is inserted into the chamber 50. In other words, the end of the second part S2 side of the first part S1 is preferably located closer to the opening 52 side than the center of the holding part 60 in the longitudinal direction. Thus, before the first part S1 of the consumable 110 abuts against the bottom wall 56a of the chamber 50, the second part S2 is inserted into the holding part 60, and a change in resistance can be felt. Since the insertion position where this change is felt is closer to the desired insertion position of the consumable 110, it is easier to position the consumable 110 in the desired position, thus improving the user experience.

[0172] <Second Implementation>

[0173] Next, the smoking system 100 of the second embodiment will be described. The smoking system 100 of the second embodiment differs from the smoking system 100 of the first embodiment in that the structure of the chamber 50 is different. Figure 14 This is a schematic cross-sectional view of the chamber 50 of the device 120 of the smoking system 100 in the second embodiment. Figure 15A yes Figure 14 A cross-sectional view of chamber 50 of 18A-18A in the view. Figure 15B yes Figure 14 The image shows a cross-sectional view of chamber 50 in the direction of view 18B-18B. Specifically, the chamber 50 of the second embodiment differs from the chamber 50 of the first embodiment in that it includes a first holding portion 70 and a second holding portion 76.

[0174] The first retaining portion 70 is configured to retain the consumable 110 inserted into the chamber 50. The second retaining portion 76 is located further away from the opening 52 of the chamber 50 than the first retaining portion 70, and is configured to retain the consumable 110 inserted into the chamber 50. The first retaining portion 70 includes a first pressing portion 72 and a first non-pressing portion 73 that press a portion of the consumable 110. The first pressing portion 72 has an inner surface 72a and an outer surface 72b. The first non-pressing portion 73 has an inner surface 73a and an outer surface 73b. The second retaining portion 76 includes a second pressing portion 77 and a second non-pressing portion 78 that press a portion of the consumable 110. The second pressing portion 77 has an inner surface 77a and an outer surface 77b. The second non-pressing portion 78 has an inner surface 78a and an outer surface 78b.

[0175] When the consumable 110 is held by the first holding part 70 and the second holding part 76, the second holding part 76 is configured to compress the consumable 110 more than the first holding part 70. Specifically, for example, Figure 15A as well as Figure 15B As shown, on a plane orthogonal to the longitudinal direction of the chamber 50, the cross-sectional area inside the second holding portion 76 is smaller than the cross-sectional area inside the first holding portion 70. The inner surface 72a of the first pressing portion 72 presses the consumable 110, so that in the first holding portion 70, the consumable 110 is substantially in close contact with the heating surface (the inner surface 72a of the first pressing portion 72), thus enabling efficient transfer of heat from the heating portion 40 to the consumable 110. At the same time, the airflow resistance during smoking can be adjusted by pressing the second holding portion 76. The heating portion 40 can also be disposed on the outer surface 77b of the second pressing portion 77. In particular, when the part of the consumable 110 pressed by the second holding portion 76 is the aforementioned cap, by not disposing of the heating portion 40 in the second holding portion 76, heating that does not effectively contribute to the heating of the smokeable substance can be suppressed.

[0176] like Figure 14 As shown, the chamber 50 has a second guide portion 79, which has a conical surface 79a connecting the inner surface 72a of the first pressing portion 72 and the inner surface 77a of the second pressing portion 77. The second guide portion 79 allows the cross-sectional shape of the inner surface of the chamber 50 to change continuously from the first pressing portion 72 toward the second pressing portion 77, thus enabling the consumable 110 to be smoothly inserted into the second holding portion 76.

[0177] like Figure 15A As shown, the inner surfaces 72a of the first pressing portions 72 of the first holding portion 70 are opposite to each other. That is, the inner surfaces 72a of the first pressing portions 72 form a pair of opposing first pressing surfaces. Figure 15B As shown, the inner surfaces 77a of the second pressing portions 77 of the second holding portion 76 are opposite to each other. That is, the inner surfaces 77a of the second pressing portions 77 form a pair of opposing second pressing surfaces. Preferably, the shortest distance between the second pressing surfaces is smaller than the shortest distance between the first pressing surfaces. Furthermore, in the illustrated embodiment, both the first and second pressing surfaces are planar. Figure 15A as well as Figure 15B As shown, in a direction orthogonal to the length direction of the chamber 50, the pressing surface of the second holding part 76 faces the same direction as the pressing surface of the first holding part 70.

[0178] like Figure 14 As shown, the second retaining part 76 is disposed at the end of the chamber 50. Therefore, when the smokeable material at the end of the consumable 110 is pressed, the second retaining part 76 compresses the smokeable material at the end of the consumable 110, and when the consumable 110 is removed from the chamber 50 after smoking, the amount of smokeable material falling into the chamber 50 can be reduced.

[0179] The inner surface 72a and outer surface 72b of the first pressing portion 72, as well as the inner surface 77a and outer surface 77b of the second pressing portion 77, may have the same features as the inner surface 62a and outer surface 62b of the pressing portion 62 in the first embodiment. Furthermore, the inner surface 73a and outer surface 73b of the first non-pressing portion 73, as well as the inner surface 78a and outer surface 78b of the second non-pressing portion 78, may have the same features as the inner surface 66a and outer surface 66b of the non-pressing portion 66 in the first embodiment.

[0180] <Third Implementation Method>

[0181] Next, the smoking system 100 of the third embodiment will be described. The smoking system 100 of the third embodiment differs from the smoking system 100 of the first embodiment in that the structure of the chamber 50 and the heating unit 40 are different. Figure 16This is a schematic cross-sectional view of the heater assembly 30 of the device 120 of the smoking system 100 in the third embodiment. Figure 17 yes Figure 16 A cross-sectional view of chamber 50 in the direction of view 20-20. In Figure 16 In the middle, the following was omitted. Figure 2 The top cap 32 is shown.

[0182] As shown in Figure 15 and Figure 16 As shown, the shape of the chamber 50 is approximately the same as that of the chamber 50 in the first embodiment. On the other hand, the heater assembly 30 of the third embodiment replaces the heating part 40 with an induction coil 46 for heating the chamber 50. As shown in FIG15, the induction coil 46 can also be configured as a pressing part 62 surrounding the chamber 50. This allows for efficient energy supply to the heating part of the chamber 50. Furthermore, the induction coil 46 can also be cylindrical.

[0183] The pressing portion 62 of the chamber 50 includes a base 63 heated by an induction coil 46. The base 63 may be disposed on the outer surface 62b or the inner surface 62a of the pressing portion 62, or it may be contained within the wall of the chamber 50 constituting the pressing portion 62, and the wall of the chamber 50 constituting the pressing portion 62 may also be formed by the base. The base 63 is preferably made of a material comprising at least one material selected from the group consisting of aluminum, iron, nickel, and alloys thereof (e.g., nickel-chromium alloys, stainless steel).

[0184] In the third embodiment, the non-pressable portion 66 of the chamber 50 also includes a base 63. Thus, as... Figure 17 As shown, the base 63 and the path of the current flowing through the base 63 are formed in an annular shape surrounding the space containing the consumable 110 (the internal space of the chamber 50).

[0185] As described above, in the third embodiment, at least the pressing part 62 includes a base 63, which is heated by an induction coil 46.

[0186] <Fourth Implementation>

[0187] Next, the smoking system 100 of the fourth embodiment will be described. Compared with the smoking system 100 of the first embodiment, the smoking system 100 of the fourth embodiment has a different airflow path and a different structure of the chamber 50. Figure 18 This is a diagram showing the smoking system 100 according to the fourth embodiment.

[0188] like Figure 18 As shown, in the smoking system 100 of the fourth embodiment, there is essentially no gap for obtaining air between the heater assembly 30 and the consumable 110. Figure 18As shown, in the smoking system 100, an air intake opening 30a is formed at the bottom of the heater assembly 30, and an air passage 15 for intake air is formed in this opening 30a. In the illustrated example, the air passage 15 extends in a manner that connects the opening 30a to the bottom of the smoking system 100 (opposite to the opening 52 of the chamber 50 of the heater assembly 30 into which the consumable 110 is inserted). The air passage 15 can take any shape connecting the opening 30a to the outside of the smoking system 100. Thus, the air inhaled by the user is introduced into the user's mouth from the bottom of the smoking system 100 through the end of the consumable 110, as shown by the airflow 100D.

[0189] Figure 19A This is a longitudinal cross-sectional view of the chamber 50, including the non-pressing part 66, in which the consumable 110 in the fourth embodiment is positioned at the desired location. Figure 19B This is a longitudinal cross-sectional view of the chamber 50, including the pressing part 62, in which the consumable 110 in the fourth embodiment is positioned at the desired location in the chamber 50. Figure 20A yes Figure 19B The diagram shows a cross-sectional view of chamber 50 in view 23A-23A. Figure 20B yes Figure 19B The diagram shows a cross-sectional view of chamber 50 in view of 23B-23B. Additionally, in... Figure 20B In order to make it easier to understand the pressing of the consumable 110 in the pressing part 62, a cross-section of the consumable 110 in the state before pressing is shown.

[0190] like Figure 19B As shown, when the consumable 110 is positioned in the desired position in the chamber 50, the retaining part 60 has no substantial gap between the inner surface 66a of the non-pressing part 66 and the consumable 110. Furthermore, as... Figure 19A as well as Figure 19B As shown, an opening 30a is formed in the bottom wall 56a of the bottom 56 of the chamber 50 to allow air to flow into the chamber 50.

[0191] The non-pressing part 66 preferably contacts the consumable 110 in a non-pressing state when the consumable 110 is disposed in the chamber 50. The non-pressing state here substantially includes the non-pressing state.

[0192] In the fourth embodiment, the inner circumference length of the retaining part 60 is the same as the outer circumference length of the consumable 110 before it is pressed by the pressing part 62. Furthermore, "same" here includes cases where they are substantially the same.

[0193] As described above, the holding portion 60 has a pressing portion 62 and a non-pressing portion 66. When the inner circumferential length of the holding portion 60 is substantially the same as the outer circumferential length of the consumable 110, the pressing portion 62 presses a portion of the consumable 110 so that the outer circumferential shape of the consumable 110 is approximately consistent with the cross-sectional shape of the inner surface of the holding portion 60. Compared to the case where the inner circumferential length and inner circumferential shape of the holding portion 60 are the same as the outer circumferential length and outer circumferential shape of the consumable 110, the portion of the consumable 110 pressed by the pressing portion 62 is formed in the smoking system 100, thus improving the heat transfer efficiency from the heating portion 40 to the consumable 110. In addition, compared to the case where the outer circumferential length of the consumable 110 is shorter than the inner circumferential length of the holding portion 60, the non-pressed portion of the outer circumferential surface of the consumable 110 is also substantially in contact with the inner circumferential surface of the holding portion 60 (the inner surface 66a of the non-pressing portion 66), thus improving the heat transfer efficiency from the heating portion 40 to the consumable 110. Furthermore, compared to the case where the outer perimeter of the consumable 110 is longer than the inner perimeter of the retaining part 60, the consumable 110 can be smoothly inserted into the retaining part 60, and the density strain of the outer perimeter surface and the interior (e.g., tobacco) of the consumable 110 can be suppressed. As a result, uneven heating caused by density strain inside the consumable 110 and deviations in the airflow resistance of each consumable 110 can be suppressed.

[0194] Alternatively, it can be said that the inner circumference length of the holding part 60 is preferably substantially the same as the outer circumference length of the consumable 110 in the pressed state by the pressing part 62. The inner circumference length of the holding part 60 can also be the inner circumference length of the holding part 60 on the plane orthogonal to the length direction of the chamber 50. Furthermore, the "outer circumference length of the consumable 110 before being pressed by the pressing part 62" can also be the outer circumference length of the consumable 110 before being pressed by the pressing part 62, positioned in the length direction of the chamber 50 at a position corresponding to the inner circumference length of the compared holding part 60 when pressed by the pressing part 62. Additionally, the "outer circumference length of the consumable 110 in the pressed state by the pressing part 62" can also be the outer circumference length of the consumable 110 in the pressed state, positioned in the length direction of the chamber at a position corresponding to the inner circumference length of the compared holding part 60.

[0195] In the fourth embodiment, the inner circumferential length of the chamber 50 (holding portion 60) is the same as the outer circumferential length of the consumable 110 housed in front of the chamber 50, and the inner circumferential shape of the chamber 50 (holding portion 60) on a plane orthogonal to the length direction of the chamber may also differ from the cross-sectional shape of the consumable 110 housed in front of the chamber 50 that is orthogonal to the length direction. Here, "same" includes cases where they are substantially the same.

[0196] According to this embodiment, the consumable 110 is substantially in close contact with the heating surface (the inner surface 62a of the pressing portion 62 of the chamber 50), thus enabling efficient heat transfer from the heating portion 40 to the consumable 110. Specifically, the inner circumferential length of the chamber 50 is substantially the same as the outer circumferential length of the consumable 110, and the inner circumferential shape of the chamber 50 is different from the cross-sectional shape of the consumable 110 contained in the chamber 50. Therefore, a portion of the consumable 110 is pressed against the inner surface of the chamber 50, and the outer circumferential shape of the consumable 110 is approximately consistent with the inner circumferential shape of the inner surface of the holding portion 60. Compared to the case where the inner circumferential length and inner circumferential shape of the chamber 50 are the same as the outer circumferential length and cross-sectional shape of the consumable 110, in the smoking system 100, a portion of the consumable 110 is formed where it is pressed by the chamber 50, thus improving the heat transfer efficiency from the heating portion 40 to the consumable 110. Furthermore, compared to the case where the outer periphery of the consumable 110 is shorter than the inner periphery of the chamber 50, the unpressed portion of the outer periphery of the consumable 110 is in substantial contact with the inner periphery (non-pressed surface) of the chamber 50, thus improving the heat transfer efficiency from the heating unit 40 to the consumable 110. Moreover, compared to the case where the outer periphery of the consumable 110 is longer than the inner periphery of the chamber 50, the consumable 110 can be smoothly inserted into the chamber 50, suppressing density strain on the outer periphery of the consumable 110 and its interior (e.g., tobacco). As a result, uneven heating caused by density strain within the consumable 110 and deviations in the airflow resistance of each consumable 110 can be suppressed.

[0197] Alternatively, it can be said that the inner circumference length of the chamber 50 is preferably substantially the same as the outer circumference length of the consumable 110 in the state of being pressed by the chamber 50. The inner circumference length of the chamber 50 can also be the inner circumference length of the chamber 50 on a plane orthogonal to the length direction. Furthermore, the "outer circumference length of the consumable 110 before being contained in the chamber 50" can also be the portion of the outer circumference length of the consumable 110 before being contained in the chamber 50 that, when contained in the chamber 50, is positioned in the length direction of the chamber 50 at a position corresponding to the inner circumference length of the compared chamber 50. Additionally, the "outer circumference length of the consumable 110 in the state of being pressed by the chamber 50" can also be the outer circumference length of the consumable 110 in the state of being pressed by the chamber 50 that, in the length direction of the chamber 50, is positioned at a position corresponding to the inner circumference length of the compared chamber 50.

[0198] <Fifth Implementation>

[0199] Next, the smoking system 100 according to the fifth embodiment will be described. The smoking system 100 of the fifth embodiment differs from the smoking system 100 of the first embodiment in that a cylindrical sleeve is provided around the chamber 50. Figure 21This is a schematic cross-sectional view of the chamber 50 and sleeve of the device 120 of the smoking system 100 in the fifth embodiment. Figure 22 yes Figure 21 The diagram shows a schematic cross-sectional view of chamber 50 and sleeve, viewed from direction 22-22. Figure 21 as well as Figure 22 As shown, in the smoking system 100 of the fifth embodiment, a cylindrical sleeve 80 is provided to surround the chamber 50. Furthermore, in the fifth embodiment, except for the sleeve 80, it may have the same structure and features as the smoking system 100 of the first embodiment.

[0200] like Figure 22 As shown, in a direction orthogonal to the length direction of the chamber 50, the shortest distance between the inner surface of the sleeve 80 and the outer surface 62b of the pressing part 62 is L1. Furthermore, this shortest distance refers to the shortest distance between the inner surface of the sleeve 80 and any point on the outer surface 62b of the pressing part 62. Figure 22 In the example shown, the shortest distance between the outer surface 62b of the pressing part 62 and the inner surface of the sleeve 80 is maximized. Furthermore, in a direction orthogonal to the length direction of the chamber 50, the shortest distance between the inner surface of the sleeve 80 and the outer surface 66b of the non-pressing part 66 is L2. This shortest distance L1 is greater than the shortest distance L2. That is, in the fifth embodiment, when the shortest distance between the inner surface of the sleeve 80 and the outer surface 62b of the pressing part 62 is set to L1 in a direction orthogonal to the length direction of the chamber 50, and the shortest distance between the inner surface of the sleeve 80 and the outer surface 66b of the non-pressing part 66 of the chamber 50 is set to L2, L1 is greater than L2.

[0201] According to the fifth embodiment, the distance between the outer surface 62b of the pressing portion 62 of the pressing consumable 110 and the inner surface of the sleeve 80 is longer than that of the non-pressing portion 66, thereby increasing the length (thickness) of the air layer in this gap. As a result, when the pressing portion 62 heats the consumable 110, the heat insulation efficiency based on the air layer between the pressing portion 62 and the sleeve 80 can be improved. In particular, as Figure 2 As shown, when the heating part 40 is disposed on the outer surface 62b of the pressing part 62, the pressing part 62 is more conducive to heating the consumable 110 housed in the chamber 50 compared to the non-pressing part 66, which does not contact the consumable 110. Therefore, the distance between the outer surface 62b of the pressing part 62 and the inner surface of the sleeve 80 is longer than that of the non-pressing part 66, thereby improving the heat insulation efficiency based on the air layer between the pressing part 62 and the sleeve 80, and enabling efficient heating of the consumable 110.

[0202] like Figure 21 as well as Figure 22As shown, the sleeve 80 preferably includes a heat insulation portion 80a. In this case, the chamber 50 can be surrounded by the heat insulation portion 80a, thus preventing heat transfer from the heated consumable 110 to the outside of the device 120. The heat insulation portion 80a can be cylindrical, like the sleeve 80. The heat insulation portion 80a can be, for example, an air layer, a vacuum insulation layer, aerogel, or other heat insulation material.

[0203] The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical concept described in the claims, specification, and drawings. Furthermore, any shape or material not directly described in the specification and drawings is within the scope of the technical concept of the present invention as long as it serves the function or effect of the present invention. Additionally, regarding shape, extent, etc., the shape, extent, etc., expressed as "substantively" at least in the specification are not limited to "strictly speaking, its shape, extent, etc.", but are also intended to include "the shape, extent, etc., at least within the scope of the intended function."
