The heated tobacco cartridge 1 has an insertion portion 50 into which the heated tobacco cartridge 1 is inserted. The needle is inserted into the tobacco filler 11 of the inserted heated tobacco cartridge 1. The heating element 52 is provided in the heated tobacco product body 5. The heating element 52 is electrically controlled by a control unit provided in the tobacco filler 11. The tobacco filler 11 generates heat while inserted in the tobacco container. In this state, when the user inhales through the filter 30, the aerosol In addition, the support member 20 is solid and can suck in the air flow containing the tobacco filler. By being provided between the accumulation 10 and the filter, the tobacco filler accumulation 10 is prevented from being caught in the filter. This can prevent the heat exchanger 10 from moving toward the rotor 30.

[0035] (1-2. Configuration of Support Member 20) The support member 20 is described in more detail below.

[0036] 3 is a perspective view of the support member 20. As shown in FIG. 3, the support member 20 has a first end surface The first end surface 21 of the support member 20 has a tobacco filler. The second end surface 23 of the support member 20 abuts against the end surface of the filter 30. The support member 20 has a hole 27 (also called a through hole) extending from the first end surface 21 to the second end surface 23. The support member 20 has a cylindrical shape, and the air flows through the holes 27. The material for forming the support member 20 is, for example, a silicone resin. The material of the support member 20 is not limited to silicone resin, but may be wood or metal (aluminum, etc.) that enhances the cooling effect. The insulating film 11 may be formed of a material other than a resin material, such as

[0037] 4A is a side view of the support member 20. FIG. 4B is a first end face of the support member 20. 4(A) and 4(B), the support member 20 is In a cross section cut along a plane perpendicular to the longitudinal direction D1, Up to 23 have the same shape.

[0038] The support member 20 has a hole 27 that penetrates from the first end surface 21 to the second end surface 23 . The holes 27 allow the airflow containing the aerosol generated in the tobacco filler accumulation 10 to pass through the filter 30. It functions as a flow path to allow the fluid to flow to the other side.

[0039] As shown in FIGS. 4A and 4B, the hole 27 is formed on the peripheral surface 25 so as to extend along the central axis C20 thereof. In this example, the hole 27 has a cylindrical shape. In this embodiment, six holes 27 are provided along the circumferential direction. The cores P are arranged at intervals of 60° in the circumferential direction around the central axis C20. Therefore, the six holes 27 are arranged at equal intervals in the circumferential direction. have the same radius.

[0040] The first end surface 21 has a void in the hole 27 portion and a solid portion in the other portion. The solid portion abuts against the end face of the tobacco filler accumulation 10. The tobacco filler accumulation 10 is a heating type When the heating element 52 of the cigarette body 5 is inserted, it receives a force in the longitudinal direction D1, so that it abuts against the The solid portion of the support member 20 can support the tobacco filler stack 10 .

[0041] The support member 20 has a plurality of protrusions 251 on the peripheral surface 25. The protrusions 251 are In this example, the protrusion 251 is provided on the peripheral surface of the support member 20. 25 from the first end surface 21 to the second end surface 23 in the longitudinal direction D1. Furthermore, a plurality of protrusions 251 are provided all around the circumference in the circumferential direction.

[0042] Each of the plurality of protrusions 251 has a tip 251a. In FIG. 4B, the protrusion 251 when viewed from the first end face 21 side is The imaginary line VL1 extending from the center C251 toward the tip 251a is the center of the support member 20. The protrusion 251 is formed by two side portions S25. 1, and the two side portions S251 connect the tip portion 251a and the peripheral portion 25. At this time, when the support member 20 is viewed from the first end surface 21 side, the imaginary line VL1 and the protruding portion The imaginary line VL2 is provided along the side portion S251 corresponding to the tip portion 251a of the The angle θ is an acute angle.

[0043] In this embodiment, the protrusions 251 are provided on the peripheral surface 25, so that the gripping part of the assembly machine When the support member 20 is gripped by the assembly machine, the gripping portion of the assembly machine and the tip portion 251a of the protrusion 251 contact each other. This makes it easier for the gripping part of the assembly machine to grip the support member 20. This allows for stable production of heated tobacco cartridges.

[0044] FIG. 5 is a cross-sectional view of the support member 20 wrapped in the packaging member 40. As shown in FIG. In this embodiment, the packaging material 40 wrapped around the outer periphery of the support member 20 and the support member 2 A gap 26 is provided between the peripheral surface 25 of the nozzle 20 and the protrusion 251. This allows aerogas to flow between the packaging member 40 and the peripheral surface portion 25. Therefore, the flow path of the aerogas is expanded in addition to the hole portion 27, improving the fluidity of the aerogas. Furthermore, in this embodiment, the gap 26 widens toward the packaging member 40. Therefore, the aerosol flow path is larger than when the convex portion has a substantially rectangular shape. It can be taken.

[0045] In this embodiment, the protrusions 251 have the same height in the longitudinal direction D1. In this case, the height of the protrusion 251 is preferably 0.05 mm or more and 1 mm or less. If the height of the protrusion 251 is less than 0.05 mm, the shape of the protrusion cannot be maintained. This may be difficult or the aerosol may not be able to circulate smoothly. Furthermore, if the height of the protrusion 251 exceeds 1 mm, the gap between the support member 20 and the packaging member 40 The size of the voids increases, and a part of the tobacco filler 11 enters the voids, This may make it difficult to prevent the accumulation of material 10 from moving toward the filter 30. The above range is also desirable from the viewpoint of maintaining the shape of the convex portions.

[0046] In this embodiment, the void ratio between the peripheral surface portion 25 and the packaging member 40 and the support The member 20 is configured to adjust the porosity, which is the ratio of the cross-sectional area of ​​the through holes to the cross-sectional area of ​​the support member 20. By doing so, it is possible to adjust the fluidity of the aerosol (air flow) from the tobacco filler accumulation 10. The details of porosity will be explained later.

[0047] When the support member 20 of this embodiment is wrapped in the wrapping member 40, the peripheral surface portion 25 and the wrapping member 40 A plurality of gaps 26 are provided between the electrodes 22 and the aerosol, and these gaps can serve as flow paths for the aerosol. The gaps in the first end surface of the support member 20 are a gap 26 and six holes 27. The porosity ratio of the holes 27 is preferably in the range of, for example, 1:1 to 1:12. The porosity of the pores 6 is preferably in the range of 1% to 5% of the area surrounded by the packaging member 40. The porosity of the portion 27 is preferably in the range of 1% to 60%. In this case, when pressure is applied from the outside, the packaging member 40 is crushed, and the entire cartridge is destroyed. The shape of the support member 20 cannot be maintained, or the support function of the support member 20 cannot be maintained. (For example, the tobacco filler accumulation may easily enter the gaps 26 and holes 27.) If the gap 26 is below the lower limit of the above range, the flow of the aerosol may be impaired. (For example, the flow path becomes narrower, reducing the amount of aerosol that flows, requiring more force to suction.)

[0048] In other words, by using this embodiment, when pressure is applied from the outside, the packaging member 4 The solid portion of the support member 20 supports the tobacco filler stack 10 without the support member 20 being crushed. The movement of the material toward the packaging material 40 is suppressed, and a plurality of gaps 26 are provided between the material and the packaging material 40. By this, the aerosol flows through the gaps of the voids 26 in addition to the holes 27, This can increase the effectiveness of circulating the product.

[0049] In addition to the porosity, the airflow resistance may be adjusted by the thickness and material of the packaging member 40. In this embodiment, a gap 26 is provided between the packaging member 40 and the support member 20. When the filter 30 is sucked and the inside of the packaging member 40 becomes a negative pressure state, At this time, the outside air is taken in due to the ventilation resistance of the packaging member 40. The degree to which the signal is embedded can be varied.
