International Publication No. 2020/216762 Japan Special Table No. 2021-508243 Japan Special Table No. 2021-502800

After heating consumable materials containing smokable substances, when the user of the aerosol generator (hereinafter referred to simply as the user) takes out the consumable materials from the storage section, some of the consumable materials may adhere to the heating section or the inner surface of the storage section. You may not be able to take out that part. For this reason, Patent Document 3 proposes an aerosol generating device including a rotating part that allows the aerosol forming base and the heating body to move relative to each other in the circumferential direction. The aerosol generation device of Patent Document 3 has problems such as the aerosol generation device becoming complicated or large-sized.

One of the objects of the present invention is to generate an aerosol that suppresses a part of the consumables from remaining in the storage section when the consumables are taken out from the storage section, while suppressing the complexity or enlargement of the aerosol generation device. The present invention is to provide devices and smoking systems.

According to the first aspect, an aerosol generation device is provided. This aerosol generating device includes a storage section that stores a consumable material containing a smokable substance and heats the consumable material with a heating section, and the storage section has an end portion of the consumable material inserted into the storage section. A folding part that can be folded inside the consumable product is provided.

According to the first aspect, it is possible to prevent a portion of the consumable material from remaining in the storage section when the consumable material is taken out from the storage section, while suppressing the complexity or enlargement of the aerosol generating device. This can reduce the need for maintenance such as cleaning. Moreover, by suppressing the adhesion of consumable materials to the heating section, deterioration of heating efficiency can be suppressed.

In a second aspect, in the first aspect, the folding portion folds the end portion into the consumable material when at least the end portion of the consumable material inserted into the storage portion is not folded. The gist is that.

According to the second aspect, it is possible to prevent folded portions from not being formed in the stored consumables, and more reliably prevent part of the consumables from being formed when the consumables are taken out from the storage section. Remaining in the storage part can be suppressed.

The gist of the third aspect is that in the first aspect or the second aspect, the folding section folds an end of the consumable material toward a central axis extending in the longitudinal direction of the heating section.

According to the third aspect, when taking out the consumables from the storage section, it is possible to more reliably prevent a portion of the consumables from remaining in the storage section.

A gist of a fourth aspect is that in any of the first to third aspects, the folding part includes a linear or band-shaped contact part that comes into contact with the consumable material.

When the wide abutment part abuts the end of the consumable material, the contents of the consumable material move in a direction intersecting the direction in which the abutment part presses, causing the end of the consumable material to spread. In this case, when taking out the consumables from the storage section, the contents cannot be held by the ends, and the contents tend to remain in the storage section. According to the fourth aspect, since the linear or band-shaped contact portion contacts the consumable material, the end portion of the consumable material does not spread out compared to a wide contact portion, and when the consumable material is taken out from the storage section. This makes it difficult for the contents to remain in the container.

The gist of the fifth aspect is that in the fourth aspect, the folded portion is blade-shaped.

According to the fifth aspect, when the end portion of the consumable material is folded in by the blade-like folding portion, the end portion of the consumable material is difficult to spread further, so that when the consumable material is taken out from the storage portion, the contents remain in the storage portion. It becomes difficult to do.

The gist of the sixth aspect is that in the fourth aspect or the fifth aspect, the contact portion is inclined with respect to the insertion direction of the consumable material.

According to the sixth aspect, the end portion of the consumable product can be biased toward the inside of the consumable product by the contact of the inclined contact part, so that when the consumable product is taken out from the storage part, the contents are further It will certainly be difficult for it to remain in the storage section.

In a seventh aspect, in any one of the first to sixth aspects, the accommodating part includes a bottom wall that intersects with the central axis thereof, and a side wall that extends along the central axis, and the folding part includes the The gist is that it is provided in contact with at least one of the bottom wall and the side wall.

According to the seventh aspect, the end portion of the consumable product can be folded in when storing the consumable product in the storage portion without the user having to perform complicated operations.

In an eighth aspect, based on the seventh aspect, in a certain longitudinal section including the central axis, the angle between the central axis and the portion of the folded portion that comes into contact with the consumable material is 30° or more and 60° or less. The gist is that.

According to the eighth aspect, when inserting the consumable material into the accommodating portion, the consumable material can be urged inward while making it easy to form the folded portion.

The gist of the ninth aspect is that in the seventh aspect or the eighth aspect, the folded portion has a sharp shape that becomes thinner toward the central axis along a radial direction with respect to the central axis.

According to the ninth aspect, the folding section can bias the consumable material in the radial direction toward the central axis without expanding the end portion of the consumable material, and when the consumable material is taken out from the storage section, the folding section can press the consumable material in the radial direction toward the central axis without spreading the end portion of the consumable material. becomes even more difficult to remain in the storage section.

A gist of a tenth aspect is that in any one of the seventh to ninth aspects, the accommodating portion is provided with a plurality of the folding portions at different positions in the circumferential direction with respect to the central axis.

According to the tenth aspect, the plurality of folding parts fold in the ends of the consumable material at a plurality of places, so that when the consumable material is taken out from the containing part, the contents are more difficult to remain in the containing part.

In an 11th aspect, in any of the 7th to 10th aspects, the aerosol generating device includes a plurality of the folding parts, and the plurality of folding parts are arranged at opposing positions with the heating part interposed therebetween. In a certain direction along the bottom wall of the accommodating part, the width of the heating part is 60% or more of the distance between the two folded parts.

According to the eleventh aspect, since the distance between the folding part and the heating part is short, the end of the consumable material stored in the storage part can be folded to a position close to the heating part, regardless of the width of the consumable material. This makes it more reliable that the contents are less likely to remain in the storage section when the consumables are taken out from the storage section.

The gist of a twelfth aspect is that in any of the first to eleventh aspects, the heating section includes a plate-shaped heater.

According to the twelfth aspect, the heating part can be easily inserted into the consumable material. Moreover, when forming a folding part along the width direction of a plate-shaped heater, folding of the end part of a consumable material can be facilitated.

The gist of a thirteenth aspect is that in any of the first to twelfth aspects, the heating section includes a PTC heater.

According to the thirteenth aspect, by utilizing the PTC characteristic, the temperature of the heating section can be kept below a certain temperature without the need for a control device or the like that stops heating when the temperature exceeds a predetermined temperature.

The gist of a fourteenth aspect is that in the twelfth aspect or the thirteenth aspect, the folding part is arranged at a position based on the direction in which the plate-shaped heater extends on the bottom wall of the accommodating part.

According to the fourteenth aspect, since the distance between the folding part and the heating part can be shortened, the end of the consumables stored in the storage part can be folded to a position close to the heating part, and the consumables can be more reliably consumed. When the material is taken out from the storage part, the contents are less likely to remain in the storage part. In addition, a compact aerosol generator can be realized by making the plate-shaped heater thinner in the thickness direction.

The gist of a fifteenth aspect is that in the fourteenth aspect, the folding part is arranged at a position facing at least one end of the plate-shaped heater on the bottom wall of the accommodating part.

According to the 15th aspect, since the distance between the folding part and the heating part can be shortened, the end of the consumable material stored in the storage part can be folded to a position close to the heating part, and even more reliably, When the consumables are taken out from the storage part, the contents are less likely to remain in the storage part. Furthermore, an even thinner aerosol generator can be realized.

In a 16th aspect, in the 12th to 15th aspects, the plate-shaped heater includes a first main surface perpendicular to the thickness direction and a second main surface formed on the back side of the first main surface, The accommodating section includes a biasing section that is disposed on a side wall of the accommodating section to face at least one of the first main surface and the second main surface of the plate-shaped heater, and that biases the consumable material. The gist is to have the following.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals and redundant explanation will be omitted. In the following embodiments, a tobacco stick will be described as an example of a consumable material, but the consumable material is not limited to tobacco as long as it generates flavor when heated.

FIG. 1 is a sectional view showing essential parts of a smoking system 10 according to an embodiment of the present invention in the width direction of a heating section 120. FIG. 2 is a cross-sectional view showing essential parts of the aerosol generator 100 that constitutes the smoking system 10 in the width direction of the heating section 120. FIG. 3 is a cross-sectional view showing the main parts of the aerosol generator 100 in the thickness direction of the heating section 120. FIG. 4 is a sectional view taken along line AA in FIG. The aerosol generator 100 functions as a flavor inhaler that heats the consumable material 200 containing a flavor component without burning it, and generates a flavored aerosol.

Hereinafter, the direction perpendicular to the plane on which the plate-shaped heating section 120 extends will be referred to as the thickness direction, and the direction perpendicular to the thickness direction and the longitudinal direction of the heating section 120 will be referred to as the width direction. Unless otherwise specified, the X axis is parallel to the width direction, the Y axis is parallel to the thickness direction, and the Z axis is parallel to the longitudinal direction of heating section 120 (see coordinate system CS).

The aerosol generator 100 includes a housing 110 and a heating section 120. The casing 110 has an opening 115 at one end, and functions as a housing section that accommodates at least a portion of the consumable material 200 inserted into the casing 110 through the opening 115. The housing 110 includes a side wall 111 and a bottom wall 112. A central axis AX of the accommodating portion of the housing 110 extends along the longitudinal direction of the housing 110. The side wall 111 extends along the central axis AX, and in the illustrated example, the side wall 111 has a cylindrical shape with the central axis AX as its axis. The bottom wall 112 extends in a direction intersecting the central axis AX, and in the illustrated example, is arranged substantially perpendicular to the central axis AX. In the following, the radial direction or the circumferential direction refers to the circumferential direction and the radial direction in a rotating coordinate system centered on the central axis AX. In this embodiment, a case will be explained in which the outer wall of the casing 110 and the side wall of the accommodating part are integrated. may be provided.

The housing 110 is made of resin, for example, and may be made of, in particular, PC (Polycarbonate), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (PolyEtherEtherKetone), or a polymer alloy containing multiple types of polymers. Alternatively, the housing 110 may be formed of metal such as aluminum. In the illustrated example, the housing 110 is configured such that the cross-sectional area of the housing 110 in a cross section perpendicular to the longitudinal direction is smallest near the opening 115, but the present invention is not limited to this.

Furthermore, the housing 110 includes a shaping guide (guide portion) 20, a restraining rib 30, and folding portions 50A and 50B. The shaping guide 20 forms an opening 115 and deforms the cross-sectional shape of the consumable material 200 inserted into the housing 110 to correspond to the shape of the heating section 120 . The restraining rib 30 is provided on the inner circumferential surface of the side wall 111 of the housing 110 and functions as a biasing part that biases the consumable material 200 inserted into the housing 110 toward the heating section 120. Transform. The folding portions 50A and 50B will be detailed later. In addition, if the consumable material 200 can be fixed to the heating part 120 with desired precision, the shaping guide 20 and the restraining rib 30 may not be provided.

In addition, an intake hole (not shown) is provided in the bottom wall 112 formed on the opposite side of the housing 110 from the opening 115. By supplying air to the consumables 200 housed in the housing 110 through this intake hole, the aerosol generator 100 constitutes a bottom flow type flavor inhaler. By providing the intake hole on the side opposite to the opening 115 of the housing 110, the configuration near the opening 115 of the housing 110 can be simplified.

The heating unit 120 heats the consumable material 200. In this embodiment, the heating unit 120 is inserted into the consumable material 200 housed in the housing 110 and heats the consumable material 200 from inside. It is preferable that the heating unit 120 is a plate-shaped heater. The plate-shaped heater facilitates insertion of the heating unit 120 into the consumable material 200. Further, as will be described later, by forming folding portions 50A and 50B along the width direction of the plate-shaped heater, folding of the end portion 250 of the consumable material 200 is facilitated. The heating unit 120 may include a resistance heating element and may be configured to generate heat by applying voltage from a battery (not shown). The heating unit 120 is preferably a PTC (Positive Temperature Coefficient) heater. From the viewpoint of improving heating efficiency, it is more preferable that the heating section 120 is a plate-shaped PTC heater. Furthermore, the heating unit 120 deforms the outer shape of the consumable material 200 inserted into the housing 110 along the shape of the heating unit 120 .

A PTC heater is a heater that uses a resistor that has a characteristic (PTC characteristic) that when a certain temperature (referred to as Curie temperature) is reached, the electrical resistance rapidly increases and electricity stops flowing. By utilizing PTC characteristics, the PTC heater can maintain the temperature below a certain temperature without the need for a control device or the like that stops heating when the temperature exceeds a predetermined temperature. The heating unit 120 may be a PTC heater whose resistor is barium titanate (BaTiO ₃ ) having PTC characteristics. In such a case, the heating unit 120 can set the Curie temperature of barium titanate to 350°C, and therefore can heat the consumable material 200 at a suitable temperature of less than 350°C.

FIG. 5 is a perspective view schematically showing the heating section 120. The heating section 120 has a protrusion 125 formed on one side along the longitudinal direction. The heating unit 120 is inserted into the consumable material 200 through the protrusion 125 . Therefore, the side of the heating unit 120 on which the protrusion 125 is formed is the side closer to the outside when the consumable material 200 is housed in the housing 110, and is the downstream side of the air flow path during suction. From this point of view, in the following embodiments, the side on which the protrusion 125 is formed in the longitudinal direction of the heating section 120 will be referred to as the downstream side, and the opposite side will be referred to as the upstream side.

The heating unit 120 is electrically connected to a control device (not shown), and the heating by the heating unit 120 is controlled by the control device. The control device includes a processing device such as a printed circuit board (PCB). This processing device is composed of a CPU, a memory, and the like, and controls the operation of the aerosol generating device 100. The control device detects the start of suction. Specifically, the control device detects a user's operation on an input device such as a push button or a slide switch (not shown). Alternatively, the control device detects the user's puffing motion using a sensor (not shown). After this detection, the control device performs processing to start applying voltage for heating. Further, the control device ends the heating when the end condition is satisfied. The termination condition is that a predetermined time has elapsed since the start of heating, or that the number of puff operations by the user exceeds a certain value, or the like. Note that the heating unit 120 may include a metal body inserted into the consumable material 200, and the metal body heated by induction may heat the consumable material 200. In this case, a metal body is installed in the consumable product 200 in advance, the metal body is housed in the housing 110 together with the consumable product 200, and the housing part that constitutes the housing 110 contains the metal body that has been subjected to induction heating. The heating unit 120 can heat the consumable material 200 . As described above, from the viewpoint of enabling flexible design, the accommodating part may include the heating part 120, or the accommodating part may not include the heating part 120, and the metal body is accommodated in the accommodating part together with the consumables 200. may constitute the heating section 120.

FIG. 6A is a schematic side sectional view showing the consumable material 200 according to the present embodiment. FIG. 6B is a sectional view (BB sectional view) showing a cross section of the tobacco portion 210 perpendicular to the longitudinal direction of the consumable material 200 shown in FIG. 6A. The consumable product 200 can be columnar, preferably cylindrical. As shown in FIGS. 6A and 6B, the consumable material 200 includes a tobacco part (inserted part) 210 and a paper tube 220. The tobacco part 210 is arranged on the upstream end 250 side of the consumable material 200. The tobacco part 210 has a through hole 211 in the center into which the heating part 120 is inserted. Moreover, the tobacco part 210 has a two-layered flavor release layer 212 and an elastic deformation layer 213, which are arranged so as to surround the inserted heating part 120. A wrapper 214 is wrapped around the outer periphery of the elastic deformation layer 213. Paper tube 220 is disposed downstream of tobacco section 210 and cools volatile compounds released from flavor release layer 212.

The flavor release layer 212 is composed of a tobacco sheet 212A and a non-tobacco sheet 212B disposed around the outer periphery of the tobacco sheet 212A and carrying glycerin or the like. The flavor release layer 212 is heated by the heating unit 120 and releases an aerosol or the like containing flavor. Note that the flavor release layer 212 can include only one of the tobacco sheet 212A and the non-tobacco sheet 212B.

The elastically deformable layer 213 is made of, for example, a nonwoven fabric sheet, a corrugated sheet, a non-tobacco sheet, etc., and is elastically deformable in its thickness direction (that is, in the radial direction of the cylindrical elastically deformable layer 213). The elastic deformation layer 213 contributes to deforming the consumable material 200 along the shape of the heating part 120 when the heating part 120 is inserted. Thereby, when the heating section 120 is inserted into the through hole 211, the elastically deformable layer 213 elastically deforms in the thickness direction relative to the heating section 120, making it easier to contact or approach the heating section 120. Therefore, the flavor release layer 212 can be brought into contact with or closer to the heating section 120, and the consumable material 200 can be heated efficiently.

Since the tobacco part 210 includes the flavor release layer 212 and the elastic deformation layer 213 that are arranged to surround the inserted heating part 120, when the heating part 120 is inserted into the consumable material 200, the consumption material 200 is heated. The shape can be easily changed. Note that the cross-sectional shape of the consumable material 200 may be circular or oval.

Here, the non-tobacco sheet 212B may include a flavor-generating base material. The flavor-generating base material is a material that imparts a flavor, and is preferably a tobacco material. The flavor-generating substrate may also include a flavoring agent. A fragrance is a substance that provides aroma or flavor. The fragrance may be a natural fragrance or a synthetic fragrance. One type of fragrance may be used as the fragrance, or a mixture of multiple types of fragrance may be used. Further, as the fragrance, any commonly used fragrance can be used, such as essential oils, natural fragrances, and synthetic fragrances. Moreover, it may be liquid or solid, and its properties do not matter. The flavor-generating base material may also contain a cooling agent or a flavoring agent.

Additionally, the tobacco sheet 212A may contain tobacco, polyhydric alcohol, etc., for example. Polyhydric alcohols can be used alone or in combination of two or more types in the tobacco sheet 212A. Note that polyhydric alcohol may also be added to the elastic deformation layer 213 described above. The tobacco sheet 212A can be formed into a sheet by mixing powdered tobacco and polyhydric alcohol with a binder.

As shown in FIGS. 1, 2, and 4, the housing 110 has folded portions 50A and 50B formed therein. The folding parts 50A and 50B include abutting parts 55A and 55B, respectively, which abut against the end 250 of the consumable material 200 when the consumable material 200 is housed in the housing 110. Due to this contact, the end portion 250 of the consumable product 200 is inhibited from moving in the insertion direction, and based on the shapes of the contact portions 55A and 55B, the end portion 250 receives a reaction of the force pushing the contact portions 55A and 55B, It is folded inside the consumable material 200. Here, "folding" refers to deforming the end portion 250 not only in the radial direction but also in the insertion direction. Hereinafter, when the folding parts 50A and 50B are referred to without distinction, they are referred to as the folding part 50, and when the contact parts 55A and 55B are referred to, without distinction, they are referred to as the contact part 55.

The folding section 50 is capable of folding the end portion 250 of the consumable material 200 into the inside of the consumable material 200. The folding section 50 folds the end portion 250 into the inside of the consumable material 200 when the consumable material 200 is accommodated in the housing 110. The end portion 250 is an end portion of the consumable product 200 located on the bottom wall 112 side when the consumable product 200 is housed in the housing 110. In other words, the end 250 is the upstream end of the consumable product 200. On the upstream side of the consumable material 200, the end portion 250 can extend in the length direction from the end surface to the maximum diameter of the end surface. The folding portion 50 can fold the end portion 250 into the inside of the consumable material 200, at least when the end portion 250 of the consumable material 200 inserted into the housing 110 is not folded.

As will be described later with reference to FIG. 7, the inventors believe that when the end portion 250 is folded inside the consumable material 200, when the user takes out the consumable material 200 from the casing 110, the consumable material 200 is folded into the casing 110. It was found that it becomes difficult to remain in the Thereby, it is possible to suppress deterioration in heating efficiency due to adhesion of a part of the consumable material 200, such as the heated flavor-generating base material, to the heating section 120. Furthermore, maintenance of the aerosol generating device 100 is facilitated, such as by reducing the frequency of cleaning the inside of the housing 110. The aerosol generation device 100 according to this embodiment achieves these effects without the need for complexity and enlargement.

It is preferable that the folding section 50 folds the end portion 250 of the consumable material 200 toward the heating section 120, particularly toward the central axis extending in the longitudinal direction of the heating section 120. In this embodiment, the central axis of the heating section 120 overlaps with the central axis AX of the accommodating section. In this way, when the heating section 120 is arranged on the central axis AX of the housing section constituted by the housing 110, the folding section 50 can be configured to fold the end section 250 in the radial direction. In such a configuration, when the consumable material 200 is taken out from the housing 110, the folded end portion 250 holds and pushes out the contents of the consumable material 200 disposed between the wrapper 214 and the heating section 120. It is possible to more reliably prevent the contents from remaining inside the casing 110.

The folding portion 50 is provided in contact with the side wall 111 and the bottom wall 112 of the housing 110. The contact portion 55 is provided on the opposite side of the bottom wall 112 in the folded portion 50, that is, on the downstream side. Therefore, when the consumable material 200 is inserted through the opening 115 of the housing 110, the contact portion 55 faces and abuts the end portion 250 of the consumable material 200, and can fold in the end portion 250. Therefore, the user does not need any special operation to fold the end portion 250. Note that, as long as the end portion 250 can be folded in, the folding portion 50 may be provided in contact with either one of the side wall 111 and the bottom wall 112 of the housing 110.

In this embodiment, the contact portion 55 is formed in a linear or band shape on the surface of the folded portion 50. This has the following advantages: When the wide abutment part 55 abuts the end 250 of the consumable material 200, the contents of the consumable material 200 move in a direction intersecting the direction in which the abutment part 55 presses (for example, along the Y axis). However, the end portion 250 widens. In this case, when the consumable product 200 is taken out from the casing 110, the contents cannot be held by the end portion 250, and the contents tend to fall off from the expanded end portion 250 and remain in the casing 110. Since the linear or strip-shaped contact portion 55 contacts the consumable material 200, the end portion 250 does not spread out compared to the wide contact portion 55, so that when the consumable material 200 is taken out from the casing 110, the contents do not spread out. It becomes difficult to remain in the casing 110. Note that, as long as the end portion 250 of the consumable material 200 can be folded in, the shape of the abutting portion 55 is not particularly limited, and may be formed of any flat or curved surface.

The contact portion 55 is preferably inclined with respect to the direction in which the consumable material 200 is inserted. The contact portion 55 is preferably inclined such that a tangential plane of the contact portion 55 intersects with the central axis AX on the bottom wall 112 side (upstream side) of the contact portion 55. In this embodiment, the insertion direction of the consumable material 200 is the Z-axis direction. Here, "slanted" refers to the contact portion 55 being non-perpendicular and non-parallel to the insertion direction of the consumable product. Considering manufacturing errors and the like, it is preferable that the contact portion 55 be inclined by 5 degrees or more from the insertion direction of the consumable product 200 and the direction perpendicular to the insertion direction. Since the contact portion 55 is inclined in this manner, when the consumable material 200 is housed in the housing 110, the end portion 250 of the consumable material 200 is urged toward the inside of the consumable material 200 to form a fold. Therefore, when the consumable material 200 is taken out from the casing 110, the contents of the consumable material 200 are more reliably prevented from remaining in the casing 110.

The angle formed by the central axis AX of the accommodating portion of the housing 110 and the tangential plane of the contact portion 55 is defined as an inclination angle θ. The inclination angle θ is greater than 0 degrees and less than 90 degrees. It is preferable that the inclination angle θ is 30 degrees or more. The larger the inclination angle θ is, the more the contact portion 55 comes into contact with the angle close to perpendicular to the insertion direction of the consumable product 200, making it easier to form a fold when inserting the consumable product 200 into the housing 110. The inclination angle θ is preferably 60 degrees or less. If the inclination angle θ is too large, the consumable product 200 will be difficult to fold inward, and the contents will not be retained when the consumable product 200 is taken out from the housing 110. More preferably, the inclination angle θ is within the range of 30 degrees or more and 60 degrees or less. In addition, when the contact portion 55 is a curved surface or formed in a step-like shape and the inclination angle θ takes a plurality of continuous or discrete values, the entire or part of the inclination angle θ must be within the above range. Can be done.

The shape of the folding part 50 is not particularly limited as long as the end 250 of the consumable material 200 can be folded in by the folding part 50. It is preferable that the folded portion 50 has a blade shape. Thereby, it is possible to form the contact portion 55 with a narrow width, and it is also possible to prevent the consumable material 200 from being pressed by a portion of the folded portion 50 other than the contact portion 55 and the end portion 250 from being widened.

As shown in FIGS. 1 and 4, the folded portion 50 preferably has a sharp shape that becomes thinner toward the central axis AX along the radial direction. When the folding part 50 has such a sharp shape, the contents of the consumable material 200 are pushed out in a direction intersecting the direction in which the contact part 55 presses (for example, along the Y axis), and the end part 250 spreads. can be suppressed. This makes it easier for the contact portion 55 to bias the end portion 250 of the consumable material 200 inward without spreading it, making it more difficult for the contents to remain in the casing 110 when the consumable material 200 is taken out from the casing 110. Become.

As long as the end portion 250 of the consumable material 200 can be folded in by the folding portion 50, the number of folding portions 50 disposed inside the housing 110 is not particularly limited, and may be one or more. From the viewpoint of more reliably holding the contents of the consumable material 200 by the end portion 250 having a plurality of folds, it is preferable that the housing 110 is provided with a plurality of folds 50 . In this case, from a similar point of view, it is preferable to fold the end portion 250 from a plurality of directions. Therefore, like the folded portions 50A and 50B, the end portion 250 is placed inside the housing 110 at different circumferential positions with respect to the central axis AX. It is preferable that a plurality of folding portions 50 are provided in the folding portion 50 .

The distance between the two folded portions 50A and 50B in a certain direction along the bottom wall 112, that is, along the XY plane, is defined as the folded portion distance D1. The width of the heating section 120 in this direction is defined as a heating section width W1. In the illustrated example, the folded portion distance D1 and the heated portion width W1 are measured along the X-axis direction. In this way, when the plurality of folded parts 50A and 50B are arranged at opposing positions with the heating part 120 in between, the heating part width W1 is 60% or more of the folded part distance D1 in a certain direction along the bottom wall 112. It is preferably 70% or more, and more preferably 70% or more. Because the distance between the folding section 50 and the heating section 120 is short, the end portion 250 of the consumable material 200 housed in the casing 110 can be folded to a position close to the heating section 120 regardless of the width of the consumable material 200. Can be done. Therefore, when the consumable material 200 is taken out from the end portion 250, the contents are more likely to remain inside the casing 110.

In the illustrated example, the folded portions 50A and 50B are each arranged along the X-axis direction, which is the direction in which the plate-shaped heater forming the heating portion 120 extends. In this way, it is preferable that the folding portion 50 be arranged at a position based on the direction in which the heating portion 120 extends in the bottom wall 112. Thereby, the distance between the folding section 50 and the heating section 120 can be shortened. Moreover, the aerosol generator 100 can be formed thin in the thickness direction, and can be made compact. Note that as long as the end portion 250 can be folded in by the folding portion 50, the position, angle, etc. of the folding portion 50 can be adjusted as appropriate.

The folding portion 50A is arranged to face one end of the heating portion 120 on the minus side in the X-axis direction (width direction). The folding section 50B is arranged to face one end of the heating section 120 on the plus side in the X-axis direction. In this way, the folding section 50 can be disposed in the bottom wall 112 at a position facing one end, preferably both ends, of the plate-shaped heating section 120. Thereby, the distance between the folding section 50 and the heating section 120 can be further shortened. Further, the aerosol generator 100 can be made thinner in the thickness direction, and can be made more compact.

As shown in FIG. 3, the plate-shaped heater constituting the heating section 120 has a first main surface 1201 perpendicular to the thickness direction (Y-axis direction) and a second main surface formed on the back side of the first main surface 1201. It has a surface 1202. The restraining rib 30 is formed on the side wall 111 facing the first main surface 1201 and the second main surface 1202. On the other hand, the folded parts 50A and 50B are arranged along the width direction of the heating part 120. When the folding parts 50A and 50B press the end part 250 along the width direction, the contents of the consumable material 200 can be pushed out in the thickness direction that intersects with the direction in which the folding parts 50A and 50B are pressed. Therefore, the restraining ribs 30 urge the consumables 200 inward along the thickness direction, thereby suppressing the spread of the end portions 250, so that when the consumables 200 are taken out from the casing 110, the contents do not enter the casing 110. Remaining can be suppressed. The restraining rib 30 may be disposed facing only either the first main surface 1201 or the second main surface 1202.

The material of the folding part 50 is not particularly limited as long as it can withstand the heat of the heating part 120 and can be processed into the shape. The folding portion 50 may be formed of, for example, resin such as PC, ABS resin, PEEK, or polymer alloy, or metal such as aluminum. The method of forming the folded portion 50 is not particularly limited. After forming the side wall 111 and bottom wall 112 of the casing 110, the folded portion 50 can be attached by adhesive or the like. Alternatively, the folded portion 50 may be integrally formed with the side wall 111 and the bottom wall 112 by resin molding or die casting.

FIG. 7 is a side view schematically showing the consumable material 200 folded in by the folding parts 50A and 50B, and FIG. ) is a conceptual diagram showing the end face of the. In the consumable material 200, a tobacco portion 210 is formed on the upstream side, and a paper tube 220 is formed on the downstream side. Both ends along the width direction of the upstream end 250 of the tobacco portion 210 are folded inward by folding portions 50A and 50B, respectively. In FIG. 7, an example of the outline of the folded portion of the end portion 250 is schematically shown with a two-dot chain line.

In FIG. 8, the outline of the cross section of the heating section 120 is schematically shown with a broken line. The consumable material 200 is expanded in the width direction (X-axis direction) in which the heating section 120 extends due to the insertion of the heating section 120 . At the end portion 250, the pressed portion 219 that the contact portion 55 abuts is pressed more strongly and urged toward the inside of the consumable material 200. In this embodiment, since the contact portion 55 is linear or band-shaped, the pressed portion 219 is also linear or band-shaped. The folded portion of the wrapper 214 constituting the end portion 250 extends obliquely toward a direction perpendicular to the insertion direction (Z-axis direction) of the consumable product 200 . Therefore, when the consumable material 200 is taken out from the housing 110, this portion functions as a holding portion 218 that holds the contents such as the flavor release layer 212 in the insertion direction. In the illustrated example, the holding portion 218 partially covers the tobacco sheet 212A, the non-tobacco sheet 212B, and the elastic deformation layer 213. However, the range of the end surface of the consumable material 200 covered by the holding part 218 is not particularly limited as long as the effect of preventing the contents from remaining in the casing 110 to a desired extent when the consumable material 200 is taken out from the casing 110 is not particularly limited.

As shown in FIG. 4, from the viewpoint of smooth folding, the accommodating part constituted by the housing 110 is adjacent to the folding part 50 in the circumferential direction with respect to the central axis AX, and is a non-folding part in which the end part 250 is not folded. It is preferable to include a folding part 155. In other words, it is preferable that the folded portion 50 does not have the abutment portion 55 that is continuous over the entire circumference in the circumferential direction.

Next, when the consumable material 200 is housed in the aerosol generator 100, that is, when the consumable material 200 is inserted from one end side (downstream side) to the other end side (upstream side) of the housing 110, The relationship between the housing 110 and the heating section 120 will be explained. 9 to 11 are cross-sectional views showing how the consumables 200 are accommodated in the aerosol generator 100. Note that in FIGS. 9 to 11 , the flavor release layer 212 and the elastic deformation layer 213 of the consumable material 200 are shown as one annular sheet 215.

FIG. 9 shows the state when the consumable material 200 passes through the shaping guide 20 in a cross section in the width direction of the heating section 120 and in a cross section perpendicular to the longitudinal direction of the casing 110 at the entrance section 22 of the shaping guide 20. . FIG. 10 shows the state when the consumable material 200 passes through the restraining rib 30 in the cross section of the heating section 120 in the width direction, and in the longitudinal direction of the casing 110 at the middle part and the other end of the restraining rib 30. A perpendicular cross section is shown. FIG. 11 shows a state in which the consumables 200 are housed in a predetermined storage position of the housing 110, in a cross section in the width direction of the heating unit 120, and in the longitudinal direction of the housing 110 near the other end of the heating unit 120. A cross section perpendicular to the direction is shown.

As shown in FIG. 9, the shaping guide 20 has a tapered part 21, an entrance part 22, and a deformed part 23. The tapered portion 21 is configured to expand toward one end of the housing 110 and guides insertion of the consumable material 200 into the aerosol generating device 100. The inlet portion 22 is provided at the end of the housing 110 and has an elliptical cross section, and has a major axis greater than or equal to the major axis of the consumable product 200 after being accommodated in the housing 110 and a minor axis that is greater than or equal to the major axis of the consumable product 200 after being accommodated in the housing 110. The length of the consumable product 200 is approximately the same as the diameter of the consumable product 200 before being wrapped. Further, the deformable portion 23 is provided on the inner circumferential surface of the housing 110 and has an elliptical cross section, and is configured such that the minimum inner circumferential length is approximately equal to the outer circumferential length of the consumable material 200. As a result, when the consumable material 200 passes through the shaping guide 20, the entire circumference of the consumable material 200 comes into contact with the deformation section 23, so that the cross-sectional shape of the consumable material 200 can be deformed along the shape of the entrance section 22. can.

As shown in FIG. 10, the heating section 120 has a protrusion 125 that is pointed at one end. Therefore, the heating section 120 can be easily inserted into the consumable material 200. The heating section 120 is configured to increase in width toward the other end. Thereby, as the consumable material 200 is inserted through the shaping guide 20, the outer shape of the consumable material 200 is deformed along the shape of the heating section 120. Specifically, the consumables 200 are pushed out in the width direction of the heating section 120 . Thereby, the consumable material 200 can be brought into close contact with the heating section 120, and the efficiency of heat transfer from the heating section 120 to the consumable material 200 can be improved. Further, by the heating unit 120 pushing the consumable material 200 wider, it is possible to prevent the consumable material 200 from falling off.

In the illustrated example, the heating unit 120 has a flat plate shape, and deforms the outer shape of the consumable material 200 inserted into the housing 110 into an elliptical cross-sectional shape. At this time, the long axis of the consumable material 200 after being accommodated in the casing 110 is longer than the diameter of the consumable material 200 before being accommodated in the casing 110. The short axis is shorter than the diameter of the consumable product 200 before being accommodated in the housing 110. By changing the outer shape of the consumable material 200 inserted into the casing 110 into an elliptical cross-sectional shape by the heating unit 120, the distance in the width direction of the casing 110 that the consumable material 200 occupies becomes shorter. Therefore, the housing 110 can be made thinner. Further, by changing the outer shape of the consumable material 200 inserted into the housing 110 into an elliptical cross-sectional shape, the contact area between the heating section 120 and the consumable material 200 can be increased. Therefore, the efficiency of heat transfer from the heating section 120 to the consumable material 200 can be improved.

As shown in FIG. 11, when the end 250 of the consumable product 200 reaches the bottom wall 112, the folding parts 50A and 50B fold the end 250 inward. Further, in a state where the consumable material 200 is stored in a predetermined storage position of the housing 110, an air layer 40 is formed between the consumable material 200 and the housing 110 over the entire circumference of the consumable material 200. Since the air layer 40 has a low thermal conductivity, it can provide heat insulation between the consumable material 200 and the housing 110, and the energy required to heat the consumable material 200 can be reduced. Further, the inlet portion 22 is in contact with the consumable material 200 over the entire outer circumference of the consumable material 200, and seals the air layer 40. This suppresses air convection in the air layer 40.

The following modifications are also within the scope of the present invention, and can be combined with the above embodiments or other modifications. In the following modified examples, parts having the same structures and functions as those in the above-described embodiment will be referred to with the same reference numerals, and descriptions thereof will be omitted as appropriate.

(Modification 1)
In the above-described embodiment, the abutting portion of the folding portion may have a steeper inclination with respect to the bottom wall as the distance from the central axis increases.

FIG. 12 is a schematic side sectional view showing the configuration of an aerosol generator 100A of this modification. The aerosol generator 100A has the same configuration as the aerosol generator 100 of the above-described embodiment, but instead of the folding parts 50A and 50B, the folding parts 51A and 51B have contact parts 551A and 551B, respectively. This differs from the aerosol generator 100 in that it is provided. When the folding portions 51A and 51B are referred to without distinction, they are referred to as the folding portion 51. When the abutting portions 551A and 551B are referred to without distinction, they are referred to as the abutting portion 551. The folding part 51 has a bottom surface (not shown) similar to the folding part 50 of the above-described embodiment, but the contact part 551 has a curved shape convex to the upstream side, unlike the contact part 55 of the above-described embodiment. Or band-shaped. Thereby, it is possible to provide an aerosol generating device 100A in which insertion of the consumable material 200 into the housing 110 is hardly hindered while the end portion 250 is folded in by the folding portion 51.

(Modification 2)
In the embodiment described above, the abutment part of the folding part may have a gentler inclination with respect to the bottom wall as the distance from the central axis increases.

FIG. 13 is a schematic side sectional view showing the configuration of an aerosol generator 100B of this modification. Aerosol generator 100B has the same configuration as aerosol generator 100 of the above-described embodiment, but instead of folding parts 50A and 50B, folding parts 52A and 52B have contact parts 552A and 552B, respectively. This differs from the aerosol generator 100 in that it is provided. When the folding portions 52A and 52B are referred to without distinction, they are referred to as the folding portion 52. When the abutting portions 552A and 552B are referred to without distinction, they are referred to as the abutting portion 552. The folding part 52 has a bottom surface (not shown) similar to the folding part 50 of the above-described embodiment, but the contact part 552 has a curved shape convex toward the downstream side, unlike the contact part 55 of the above-described embodiment. Or band-shaped. This makes it easier for the contact portion 552 to come into contact with the end portion 250, making it possible to provide the aerosol generating device 100B in which the end portion 250 can be folded more reliably.

(Modification 3)
In the embodiments described above, the heating section may be a pin type heater.

FIG. 14 is a schematic side sectional view of an aerosol generator 100C according to this modification, and FIG. 15 is a DD sectional view of FIG. 14. The side cross section in FIG. 14 corresponds to the EE cross section in FIG. The aerosol generator 100C has the same configuration as the aerosol generator 100 in the above-described embodiment, but has a heating unit 121 instead of the heating unit 120 and a housing 110A instead of the housing 110. It differs from the aerosol generator 100 in that the

The heating section 121 extends along the central axis AX, and includes a heating section main body 121A and a protrusion 125. A sharp protrusion 125 is formed on the downstream side of the columnar heating section main body 121A. In the heating section 121, a heating element is disposed in a heating section main body 121A disposed inside a housing section constituted by the housing 110. Thereby, the heating unit 121 can heat the consumable material 200 into which the heating unit 121 is inserted from the inside. The heating element is not particularly limited as long as it can heat the consumable material 200, and may be, for example, a heating wire or a metal body that generates heat by induction heating. The shape of the heating section main body 121A is not particularly limited, but may be cylindrical or polygonal. Among these, it is preferable that the heating section main body 121A has a cylindrical shape in order to facilitate insertion into the consumable material 200. Further, the heating section main body 121A may be installed inside the consumable material 200 in advance. In this case, the accommodating part constituted by the housing 110 can heat the consumable material 200 by induction heating the heating section main body 121A arranged in the accommodating part together with the consumable material 200.

The housing 110A includes a side wall 111A, a bottom wall 112A, and folding portions 53A, 53B, and 53C. The folding portions 53A, 53B, and 53C include contact portions 553A, 553B, and 553C, respectively. Below, when referring to each of the folding parts 53A, 53B, and 53C without distinguishing them, they will be referred to as folding parts 53. Further, when referring to each of the contact portions 553A, 553B, and 553C without distinguishing them, they are referred to as contact portions 553. The shape of the housing 110A is not particularly limited as long as it can accommodate the consumable material 200 inserted into the heating section 121. However, from the viewpoint of folding the end portion 250 smoothly with the plurality of folding portions 53, the side wall 111A and the bottom wall 112A are preferably rotationally symmetrical about the central axis AX, and as in the illustrated example, the side wall 111A is cylindrical. It is more preferable that the bottom wall 112A has a circular shape.

The shape of the folding portion 53 is similar to the folding portion 50 of the above embodiment, but is not particularly limited as long as the end portion 250 can be folded. In this modification, three folded portions 53A, 53B, and 53C are formed in contact with the side wall 111A and the bottom wall 112A and are three-fold symmetrical about the central axis AX, that is, at intervals of 120 degrees. The number of folding portions 53 may be 1, 2, or 4 or more. The contact portion 553 has a similar shape to the contact portion 55 of the above-described embodiment, but is not limited thereto.

Even when the heating section 121 is a pin-type heater as in this modification, the folding section 53 can be installed in the casing 110A, and the end 250 of the consumable material 200 can be folded in. Thereby, when the consumable material 200 is taken out from the casing 110A, it is possible to prevent the contents of the consumable material 200 from remaining in the casing 110A.

(Modification 4)
In the embodiment described above, the heating unit 120 has an internal heating type configuration in which the heating unit 120 heats the consumable material 200 from inside the consumable material 200. However, the heating unit 120 may be arranged on at least one of the side wall 111 and the bottom wall 112 of the casing 110 and heat the consumable material 200 housed in the casing 110 from the outside. Even in such a case, the end portion 250 of the consumable material 200 is folded in by the folding part 50, so that when the consumable material 200 is taken out from the casing 110, a part of the consumable material 200 will not remain in the casing 110. It can be suppressed. In particular, it is possible to prevent the portion of the end portion 250 near the end surface from adhering to the bottom wall 112 or the like.

Although the embodiments of the present invention have been described above, the embodiments of the invention described above are for facilitating understanding of the present invention, and are not intended to limit the present invention. The present invention may be modified and improved without departing from its spirit, and the present invention includes equivalents thereof. In addition, it is possible to combine or omit each component described in the claims and the specification to the extent that at least part of the above-mentioned problems can be solved or at least part of the effect can be achieved. .
