An example of the dimensions of such filler 11 is 1.5 mm long side, 0.3 mm short side, and 12 mm long.

Next, specific examples of raw materials used as the filler 11 will be described. The filling 11 is composed of any one or more combinations of raw materials shown below.

The filling 11 is made from tobacco plants or non-tobacco plants. Tobacco plants include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, and the like. Non-tobacco plants include plants other than tobacco plants. Preferred parts of non-tobacco plants include leaves, pulp, seeds, roots (scales, tuberous roots, etc.), stems, tubers, skins (stem bark, bark, etc.), flowers (petals, stamens, pistils, etc.), trunks, branches. etc.

As used herein, the term "plant" means a group of animals, and in addition to organisms such as grasses and trees that live in a fixed location with roots, microalgae, seaweeds, etc. Also includes algae such as algae, fungi such as mushrooms, and the like.

For example, if the part of the non-tobacco plant is a leaf, preferably tea can be used. Not only are tea plants different in tea, but even the same plant can be made into different teas depending on the processing method. Specifically, for example, Japanese tea, black tea, Angelica keiskei tea, sweet tea, Gynostemma tea, aloe tea, ginkgo biloba tea, oolong tea, turmeric tea, oak tea, eleuthero tea, plantain tea, persimmon tea, persimmon leaf tea, Chamomile tea, chamomile tea, Kawahara tea, quince tea, chrysanthemum tea, gymnema tea, guava tea, wolfberry tea, soft leaf tea, black soybean tea, gennoshoko tea, brown rice tea, burdock tea, comfrey tea, bifu tea , cherry blossom tea, saffron tea, shiitake mushroom tea, perilla tea, jasmine tea, ginger tea, horsetail tea, sekisho tea, assembly tea, buckwheat tea, taranogi tea, dandelion tea, sugar bean tea, dokudami tea, eucommia tea, soybean tea, elderberry tea , mouse wax tea, pigeon barley tea, habu tea, loquat leaf tea, pu-erh tea, safflower tea, pine needle tea, mate tea, barley tea, megusurinoki tea, mugwort tea, eucalyptus tea, luohan fruit tea, rooibos tea, bitter gourd tea and the like.

(1-3. Structure of Susceptor Member 13)
A susceptor member 13 is provided inside the packing assembly 10 . In this embodiment, one cylindrical susceptor member 13 is provided at the center of the packing assembly 10 . The susceptor member 13 can be induction heated by a magnetic field generated from the outside (coil). Therefore, the susceptor member 13 is made of a metallic material containing a magnetic material. Magnetic substances are roughly classified into ferromagnetic substances, paramagnetic substances, and diamagnetic substances. Among magnetic materials, ferromagnets are materials that strongly assume magnetism in the same direction as the external magnetic field when an external magnetic field is applied, and retain strong magnetism even when the external magnetic field is zero. Ferrite iron, ferrite powder, ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel, nickel, cobalt, and the like. The relative magnetic permeability of a ferromagnetic material is much greater than 1. For example, iron is about 5000, nickel is about 600, cobalt is about 250, and ferritic stainless steel is about 250. It is about 1000-1800.

Among magnetic substances, a paramagnetic substance is a material that becomes weakly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, and loses its magnetism when the external magnetic field is reduced to zero. Examples include aluminum, platinum, and manganese. . The relative permeability of a paramagnetic material is slightly greater than 1. For example, aluminum is about 1.000021, platinum is about 1.000265, and manganese is about 1.000830. A diamagnetic material among magnetic materials is a material that becomes weakly magnetized in the direction opposite to the external magnetic field when an external magnetic field is applied, and loses its magnetism when the external magnetic field is reduced to zero. Examples include copper, graphite, chromium, and bismuth. is mentioned. The relative magnetic permeability of a diamagnetic material is slightly less than 1. For example, copper is about 0.999990, graphite is about 0.99980, and bismuth is about 0.999834. .

In ferromagnetic materials, when an alternating magnetic field is generated, not only does an induced current flow and Joule heat is generated, but also heat (hysteresis loss) is generated due to friction and vibration between molecules. Induction heating can be performed more easily than in the conventional method, and the packed assembly 10 can be sufficiently heated.

In addition, ferromagnetic materials have a high Curie temperature, for example, nickel is about 358°C. Therefore, even when the smoking device cartridge 1 is heated at a high temperature of 200° C., for example, the heating temperature does not reach the Curie temperature, the properties of the ferromagnetic material can be maintained, and the filling assembly 10 can be heated stably. can.

The susceptor member 13 is made of a ferromagnetic material such as iron, ferrite iron, ferrite powder, ferrite particles, ferrite stainless steel, ferromagnetic steel, stainless steel (SUS430), nickel, cobalt, or a combination thereof. A metal material may also be used. For example, a combination of ferritic stainless steel and nickel may be used. Also, the susceptor member 13 may be made of a metal material containing a ferromagnetic material as a main component. good. Examples thereof include nickel alloys and nickel-iron alloys, and more preferably alloys in which iron is combined with chromium and aluminum. Even in this case, the filling assembly 10 can be sufficiently heated by inductively heating the ferromagnetic material. A metal material including a paramagnetic substance and a diamagnetic substance may be used instead of the ferromagnetic substance. Even in this case, induction heating itself is possible. However, from the viewpoint of shortening the heating time and reducing power consumption, it is preferable to use a metal material containing a ferromagnetic material.

The susceptor member 13 may be made of a combination of ferromagnetic, paramagnetic, or diamagnetic materials. For example, a first susceptor member made of nickel, which is a ferromagnetic material, and a second susceptor member made of iron, which is a ferromagnetic material, are physically adhered together, or Physical contact between the susceptor member and a third susceptor member made of aluminum, which is a paramagnetic material, and coating of the outer surface of the first susceptor member with the third susceptor member may be mentioned. .

Further, the susceptor member 13 may be made of a magnetic material or a material other than the magnetic material, and the surface of the material is plated with a magnetic material. For example, the susceptor member 13 may be an iron surface plated with zinc or nickel.

In the above description, as shown in FIG. 3, the longitudinal length L13 of the susceptor member 13 is desirably equal to or greater than the longitudinal length L11 of the filler 11 .

The length L13 of the susceptor member 13 accounts for 100% of the total length of the packed assembly 10 . In this example, the susceptor member 13 has a length that spans the entire length of the packing stack 10 . Note that the susceptor member 13 does not have to extend over the entire length of the packed assembly 10, and it is sufficient that the length of the susceptor member 13 accounts for 25% or more and 100% or less of the overall length of the packed assembly 10. FIG. Since the longitudinal length L13 of the susceptor member 13 is equal to or greater than the longitudinal length L11 of the filler 11, the outer surface of the filler 11 is in contact with any position on the outer surface of the susceptor member 13. is ensured, the temperature of the filling can be reliably raised.

In this embodiment, the length of the susceptor member 13 is preferably greater than 9 mm. In this example, the susceptor member 13 has a length of 12 mm. Also, the diameter of the susceptor member 13 is preferably 0.5 mm or more. In this embodiment, the diameter of the susceptor member 13 is 1 mm. Also, the volume of the susceptor member 13 is preferably 2.5 mm ³ or more. In this embodiment, the volume of the susceptor member 13 is 9.4 mm ³ .

(1-4. Structure of support member)
The support member 20 suppresses the movement of the aggregated filler 10 toward the support member 20 and allows the airflow containing the aerosol generated in the aggregated filler 10 to flow toward the filter 30 . The support member 20 is, for example, cylindrical and solid, and is arranged between the filler 11 and the filter 30 so that its axial direction is along the central axis C. As shown in FIG. The support member 20 is formed with a length along the central axis C of 3.0 mm or more and 50 mm or less, for example. Note that the support member 20 may have dimensions different from those described above depending on the function and configuration as appropriate.

(1-5. Configuration of filter)
The filter 30 is formed in a cylindrical shape, for example, with a diameter of 6.5 mm to 7.5 mm and a length along the central axis C of 50 mm or less. The filter 30 is a part that constitutes the mouthpiece of the smoking device cartridge 1 . The filter 30 is formed using paper or the like, for example. The filter 30 may be provided in a cylindrical shape by winding a sheet-like member made of paper, for example, or may include a cellulose acetate filter or the like for removing fine particles. The filter 30 has a function of filtering some of the fine particles in the water vapor and aerosol generated in the packing assembly 10 .

(1-6. Configuration of smoking system)
FIG. 4 is a cross-sectional view of a smoking system 100 showing a usage pattern of the smoking device cartridge 1. As shown in FIG. FIG. 5 is a block diagram of the smoking article main body 5. As shown in FIG. The smoking article cartridge 1 is attached to the smoking article main body 5 and used. As shown in FIG. 4 , the smoking article body 5 includes an insertion section 50 , a control device 51 , a DC/AC inverter 52 , a power supply section 53 and a coil 55 . The smoking implement cartridge 1 is inserted into the insertion portion 50 . Control device 51 , DC/AC inverter 52 , power supply section 53 , and coil 55 are provided inside smoking article main body 5 . The coil 55 is provided at a position corresponding to the filler stack 10 in the smoking device cartridge 1 inserted into the insertion portion 50 . Specifically, the coil 55 is provided on the distal portion 50b of the insertion portion 50 opposite to the entrance (proximal portion) 50a.

As shown in FIG. 5, in the smoking article main body 5, the control device 51 includes a CPU (Central Processing Unit) 511, a memory 513 composed of a RAM (Random Access Memory) and a ROM (Read On Memory), and an input/output interface. 515. The control device 51 uses a program stored in the memory 513 to perform arithmetic processing with the CPU 511 . The input/output interface 515 is connected to the DC/AC inverter 52 and the coil 55 to input/output information. A power supply unit 53 supplies a DC current to the control device 51 . A DC/AC inverter 52 provides a high frequency AC current. That is, in the smoking article main body 5 , the direct current supplied from the power supply section 53 is converted into alternating current having a predetermined frequency by the DC/AC inverter 52 based on the command from the control device 51 . The alternating current is supplied to the coil 55 .

Based on the above, an alternating current is applied to the coil 55 when the smoking article main body 5 is activated. The frequency of the alternating current at this time is preferably controlled at less than 1 MHz, preferably from 1 kHz to 800 kHz, more preferably from 50 kHz to 500 kHz, in consideration of the effects of electromagnetic waves on the human body. As a result, an electromagnetic field is generated by the coil 55 at the distal portion 50b of the insertion portion 50 of the smoking device body 5 while suppressing the effects on the human body. The susceptor member 13 of the packing assembly 10 is located within this electromagnetic field when the packing assembly 10 is properly positioned within the insert 50 . The electromagnetic field creates eddy currents in the susceptor member 13 which result in resistive heating of the susceptor member 13 against the eddy currents. The heated susceptor member 13 heats the fill 11 of the fill stack 10 to a temperature sufficient to form an aerosol. The aerosol is drawn downstream through the packing mass 10 and inhaled by the user.

By using the smoking system of this embodiment, the filling is stably heated by the susceptor member 13 that generates heat by induction heating while suppressing the influence of electromagnetic waves on the human body. This makes it possible to enjoy a stable fragrance. Also, at this time, the blade-shaped heat generating element is not inserted into the packed stuff 10 in the smoking article main body 5 . Therefore, falling off of the filling can be suppressed.

<Second embodiment>
In the first embodiment of the present invention, an example in which one cylindrical susceptor member 13 is provided at the center of the packing assembly 10 is shown, but the present invention is not limited to this. In this embodiment, an example in which a plurality of susceptor members are provided will be described. In addition, in this embodiment, description of the same configuration as in the first embodiment will be omitted as appropriate. Also, for the sake of explanation, fillings in the drawings are simply described.

FIG. 6 is an end view of the packing assembly 10A viewed from the outside. As shown in FIG. 6, the packing assembly 10A includes two susceptor members 13A (susceptor members 13A-1 and 13A-2) in addition to the packing 11 and packaging member 15. As shown in FIG. The susceptor member 13A-1 and the susceptor member 13A-2 are separated by a predetermined distance. The susceptor member 13A-1 and the susceptor member 13A-2 may be spaced apart at a predetermined distance from the central axis C, or at a predetermined angle with respect to the central axis C. may be separated by The susceptor member 13A-1 and the susceptor member 13A-2 in this embodiment are spaced apart from the center axis C with a predetermined distance therebetween, and each susceptor member is located on the center axis C of the packing assembly 10A. The center of the susceptor member is placed at a position obtained by equally dividing the length from the to the outer periphery. When the susceptor member 13A-1 and the susceptor member 13A-2 need not be described separately, they will be described as the susceptor member 13A.

The susceptor member 13A-1 and the susceptor member 13A-2 may be made of the same magnetic material, or may be made of different magnetic materials. By forming the susceptor member 13A-1 and the susceptor member 13A-2 from different magnetic materials, the susceptor member can be easily manufactured at low cost. For example, the manufacturing cost of the entire susceptor can be reduced by mixing a ferromagnetic material with a paramagnetic material. In addition, by using a ferromagnetic material for temperature control to detect changes in the Curie point and using a material other than the ferromagnetic material with good thermal efficiency for heat generation, different functions can be imparted. Further, in this embodiment, the susceptor member 13A has a cylindrical shape. At this time, the susceptor member 13A may have the same length as the susceptor member 13 of the first embodiment. On the other hand, the diameter of the susceptor member 13A may be smaller than the diameter of the susceptor member 13 of the first embodiment. For example, the susceptor member 13A may have a diameter of 0.5 mm or more. The diameter of the susceptor member 13A in this embodiment is 0.55 mm. Also, the volume of the susceptor member 13A is preferably larger than 2.5 mm ³ . The volume of the susceptor member 13A in this embodiment is 2.85 mm ³ .

In this embodiment, the total surface area of the susceptor members 13A is increased by having the two susceptor members 13A. Therefore, even if the diameter of each susceptor member 13A is reduced, it can have a heating function for the filler 11 equal to or greater than that of the susceptor member 13A.

Although the susceptor member 13A has a cylindrical shape, the present invention is not limited to this. For example, FIG. 7 is an end view of the packing assembly 10B viewed from the outside and an enlarged view of the susceptor member. As shown in FIG. 7, the packing assembly 10B has a susceptor member 13B (susceptor member 13B-1, susceptor member 13B-2). The susceptor member 13B may have an uneven portion 14 on its outer peripheral surface. As a result, the surface area of the susceptor member 13B can be increased, and the area of contact with the filler 11 is increased. Therefore, the heating function of the filler 11 can be further enhanced. The shape, number, dimensions, and arrangement of the uneven portions 14 are not limited to the example in FIG. 7, and can be set arbitrarily. The uneven portion 14 has, for example, a distance of 1.0 mm or less from the surface of the susceptor member 13A to the highest projecting top, and a distance of 1.0 mm from the surface of the susceptor member 13A to the deepest portion toward the center. It can be in the following range. Further, the uneven portion 14 can also be provided in the susceptor 13 of the first embodiment.

FIG. 8 is an end view of the packing assembly 10C viewed from the outside. As shown in FIG. 8, the packing assembly 10C has six susceptor members 13C (susceptor members 13C-1 to 13C-6). The susceptor members 13C are spaced apart at a predetermined interval so that the angle θ between the center C and the center of two adjacent susceptor members 13C is 60°. Since the susceptor member 13C has six susceptor members 13, the surface area is further improved. Therefore, the heating function of the filler 11 can be further enhanced.

<Third Embodiment>
In the first and second embodiments of the present invention, an example in which the susceptor member 13 having a columnar shape is provided in the filler assembly 10 was shown, but the present invention is not limited to this. In this embodiment, a susceptor member 13 having a different shape will be described.

FIG. 9 is an end view of the packing assembly 10D viewed from the outside. As shown in FIG. 9, the packing assembly 10D has a susceptor member 13D. The susceptor member 13D has a cylindrical (hollow) shape. In the case of a cylindrical shape, the fillers are arranged outside and inside the susceptor member 13, so the contact area with the fillers increases. Further, the cylindrical shape makes the distance D from the coil 55, which is the heating member, to the susceptor 13D uniform. Therefore, by having a cylindrical shape, the heating function of the filling can be enhanced. The length of the susceptor member 13D is preferably greater than 9 mm. The cylindrical outer diameter of the susceptor member 13D can be arbitrarily set in the range of 1 mm or more and less than 7.5 mm, preferably in the range of 3 mm or more and 7 mm or less.

FIG. 10 is an end view of the packing assembly 10E viewed from the outside. As shown in FIG. 10, the packing assembly 10E has a susceptor member 13Ea and a susceptor member 13Eb. The susceptor member 13Ea and the susceptor member 13Eb may have different shapes. In this example, the susceptor member 13Ea has a cylindrical shape like the susceptor member 13D. Like the susceptor member 13, the susceptor member 13Eb has a cylindrical shape (solid shape). The susceptor member 13Eb is provided at the center of the susceptor member 13Ea. When it is difficult to heat the filler 11 inside the susceptor member 13Ea, the susceptor member 13Eb allows the filler 11 to be heated stably. Therefore, by having the susceptor member 13E, the heating function of the filler 11 can be enhanced. The place where the susceptor member 13Eb is arranged is not particularly limited, and may be arranged outside the susceptor member 13Ea. Preferably, the length of the susceptor member 13Eb in this example is greater than 9 mm. The diameter of the susceptor member 13Eb is preferably 0.5 mm or more. The volume of the susceptor member 13Eb is preferably 2.5 mm ³ or more. Also, the length of the susceptor member 13Ea in this example is preferably greater than 9 mm. The cylindrical inner and outer diameters of the susceptor member 13Ea are larger than the diameter of the susceptor member 13Eb, and can be arbitrarily set within the range of 1 mm or more and less than 7.5 mm, preferably 3 mm or more and 7 mm or less, of the packing assembly 10E. . The difference (thickness) between the outer diameter and the inner diameter of the susceptor member 13Ea is preferably 0.1 mm or more. The susceptor member 13Ea and the susceptor member 13Eb may be made of the same magnetic material, or may be made of different magnetic materials.

FIG. 11 is an end view of the packing assembly 10F viewed from the outside. As shown in FIG. 11, the packing assembly 10F has a susceptor member 13F. The susceptor member 13F has a spiral shape. In the case of the spiral shape, since the filler 11 is arranged outside and inside the susceptor member 13, the contact area with the filler 11 is increased. Therefore, the heating function of the filler 11 can be enhanced. Further, the susceptor member 13F can be appropriately deformed according to the shape of the filler 11. As shown in FIG. Also, the susceptor member 13F can be formed, for example, by rolling a sheet of magnetic material. Therefore, the susceptor member 13F can be easily manufactured. Since the susceptor member 13F is a sheet body, it is possible to reduce the weight of the packed assembly 10F. The shape, number, dimensions, and arrangement of the susceptor members 13F are not limited to the example shown in FIG. 11, and can be arbitrarily set. The susceptor member 13F preferably has a length of 1.5 mm or more and a thickness of 0.1 mm or more.

FIG. 12 is an end view of the packing assembly 10G viewed from the outside. As shown in FIG. 12, the packing assembly 10G has one susceptor member 13G. The susceptor member 13G may have a plate shape. At this time, the susceptor member 13G preferably has a thickness of 0.1 mm or more. In this example, the thickness of the susceptor member 13G is 0.2 mm. The width of the susceptor member 13G is preferably 1.5 mm or more. In this example, the width of the susceptor member 13G is 4 mm. Also, the volume of the susceptor member 13G is preferably greater than 2.5 mm ³ . In this embodiment, the volume of the susceptor member 13G is 9.6 mm ³ .

Although one plate-shaped susceptor member is provided in FIG. 12, a plurality of plate-shaped susceptor members may be provided. FIG. 13 is an end view of the packing assembly 10H viewed from the outside. As shown in FIG. 13, the filler assembly 10H may have a plurality of plate-shaped susceptor members 13H (susceptor members 13H-1 and 13H-2). The susceptor member 13H-1 and the susceptor member 13H-2 are separated by a predetermined distance. The susceptor member 13H-1 and the susceptor member 13H-2 may be spaced apart at a predetermined distance from the central axis C, or may be spaced from the central axis C at a predetermined angle. may be separated by The susceptor member 13H-1 and the susceptor member 13H-2 in this embodiment are separated from the central axis C by a predetermined distance, and each susceptor member is separated from the central axis C of the packing assembly. The susceptor member is arranged so that the center of the susceptor member comes to a position where the length to the outer periphery is equally divided. In this example, the susceptor member 13H-1 and the susceptor member 13H-2 have the same shape. It may be made of different magnetic materials. The thickness of the susceptor member 13H is similar to that of the susceptor member 13G. On the other hand, the width of the susceptor member 13H may be smaller than that of the susceptor member 13G. At this time, the width of the susceptor member 13H is preferably 1.5 mm or more. In this example, the width of the susceptor member 13H is 1.5 mm. At this time, the volume of the susceptor member 13H is 7.2 mm ³ , which is smaller than that of the single susceptor member 13G. In this embodiment, having two susceptor members 13H may reduce the total volume of the susceptor members 13H. Increased total surface area. Therefore, even if the width of each susceptor member 13H is reduced, it is possible to have a function of heating the filler 11 equal to or greater than that of the susceptor member 13G.

The susceptor member 13H may have an uneven portion on its outer peripheral surface. As a result, the surface area of the susceptor member 13H can be increased, and the area of contact with the filler 11 is increased. Therefore, the heating function of the filler 11 can be further enhanced. The shape, number, size and arrangement of the uneven portions can be set arbitrarily. For the irregularities, for example, the distance from the surface of the susceptor member 13H to the top protruding highest is 1.0 mm or less, and the distance from the surface of the susceptor member 13H to the deepest portion toward the center is 1.0 mm or less. can be in the range of Further, the uneven portion can also be provided on the susceptor 13G.

Therefore, by using this embodiment, it is possible to heat the filler and stably generate an aerosol. It is also possible to use only the filler 11J as a susceptor without providing the susceptor member 13. FIG.

At this time, the shape, number, dimensions and arrangement of the regions 11Lb are not limited to the example in FIG. 16 and can be set arbitrarily. The region 11Lb has, for example, a grain shape with a diameter of 0.3 mm or less.

FIG. 17 is a side view of the filler 11M. As shown in FIG. 17, the filling 11M includes a region 11Ma formed of an aerosol-generating material and a region 11Mb formed of a magnetic material. At this time, a plurality of regions 11Mb may be provided spaced apart in the lateral direction D2. When the filler 11M is configured in a long (strip) shape, the length of the filler 11M is preferably substantially the same as the length of the aggregated filler 10. As shown in FIG. The length of the filler 11M is preferably in the range of 10 mm to 25 mm, more preferably in the range of 10 mm to 20 mm. An example of the dimensions of such filler 11M is 1.5 mm long side, 0.3 mm short side, and 12 mm long.

<Fifth Embodiment>
In this embodiment, a susceptor member having a cylindrical shape will be described. For the sake of explanation, members other than the susceptor member will be omitted from the drawings.

As shown in FIGS. 18A and 18B, the susceptor member 13L has a cylindrical (hollow) shape. Further, the susceptor member 13L has a gap 13Ls in part (in the longitudinal direction) when viewed from the front.

Further, the susceptor member 13L can be manufactured by cylindrically winding a plate-shaped conductive member 13La (for example, a rectangular thin metal plate) having a certain thickness around a core material.

The plurality of holes 13Qb may be arranged regularly or irregularly. The susceptor member 13Q can be manufactured by punching a plurality of holes in a large plate-like conductive material 13Qa, cutting it to a desired size, and winding it into a cylindrical shape.

In this case, the width and length of the three plate-shaped conductive members may be different. By using this embodiment, the area of the susceptor member is increased, so that the filler can be heated more efficiently. The susceptor member may be formed by combining five or more plate-like conductive members.
