Further, the battery capacity of the battery 11 is preferably in the range of 100 mAh or more and 1000 mAh or less.

As shown in FIGS. 3 and 4, the atomization unit 20 has a shape extending along a predetermined direction A. The atomization unit 20 has a reservoir 21, an atomization unit 22, a flow path forming body 23, an outer frame body 24, and an end cap 25. The atomization unit 20 has a first flow path 20X arranged on the downstream side of the atomization unit 22 as an aerosol flow path extending along a predetermined direction A. In the present specification, in the aerosol flow path, the side close to the atomizing portion 22 is referred to as an upstream, and the side away from the atomizing portion 22 is referred to as a downstream.

The reservoir 21 stores the aerosol source 21A. The reservoir 21 is located around the flow path forming body 23 in a cross section orthogonal to the first flow path 20X (predetermined direction A). In the present embodiment, the reservoir 21 is located in the gap between the flow path forming body 23 and the outer frame body 24. The reservoir 21 is made of, for example, a porous body such as a resin web or cotton. However, the reservoir 21 may be composed of a tank accommodating the liquid aerosol source 21A. Aerosol source 21A contains a liquid such as glycerin or propylene glycol.

The atomizing unit 22 atomizes the aerosol source 21A by the electric power supplied from the battery 11 without combustion. In the present embodiment, the atomizing unit 22 is composed of heating wires (coils) wound at a predetermined pitch. The predetermined pitch is at least a value at which the heating wire does not contact, and is preferably a small value. The predetermined pitch is preferably, for example, 0.40 mm or less.

The flow path forming body 23 has a cylindrical shape extending along a predetermined direction A and forming the first flow path 20X. The outer frame body 24 extends along a predetermined direction A and has a cylindrical shape for accommodating the flow path forming body 23. In the present embodiment, the outer frame body 24 extends downstream from the end cap 25 and accommodates a part of the cartridge 30.

The end cap 25 is a cap that closes the gap between the flow path forming body 23 and the outer frame body 24 from the downstream side. The end cap 25 suppresses the aerosol source 21A stored in the reservoir 21 from leaking to the cartridge 30 side.

As shown in FIGS. 5 and 6, the cartridge 30 has at least a flavor source 31A that imparts flavor to the aerosol generated by the flavor aspirator 1. The cartridge 30 is attached to the flavor aspirator 1. In this embodiment, the cartridge 30 is connected to the atomization unit 20. Specifically, a part of the cartridge 30 is housed in the outer frame body 24 of the atomization unit 20 as described above.

The cartridge 30 has a shape extending along a predetermined direction A. Specifically, the cartridge 30 has a flavor source accommodating body 31, a filter 33, and a cap 34. The cartridge 30 has a second flow path 30X arranged downstream of the first flow path 20X as an aerosol flow path.

The filter 33 is composed of predetermined fibers and has a roughness to the extent that the raw material piece of the flavor source 31A does not pass through. The filter 33 is arranged downstream of the flavor source 31A. The filter 33 is, for example, an acetate filter. The cap 34 is provided downstream (on the mouthpiece side) of the filter 33. The flavor source container 31, the filter 33, and the cap 34 are preferably bonded or welded to each other.

The cartridge 30 imparts a flavor to the aerosol by passing the aerosol atomized by the atomizing unit 22. Here, it should be noted that in the present embodiment, the aerosol can be flavored without heating the flavor source 31A. It should also be noted that substantially no aerosol is generated from the flavor source 31A. However, the flavor source 31A may be heated. In this case, it is preferable that the flavor source 31A is heated at a low temperature at which an aerosol is not generated.

In the predetermined direction A, the maximum size of the cartridge 30 is preferably 40 mm or less. Further, in the predetermined direction A, the maximum size of the cartridge 30 is preferably 25 mm or less. On the other hand, in the predetermined direction A, the minimum size of the cartridge 30 is preferably 5 mm or more. Further, in the predetermined direction A, the minimum size of the cartridge 30 is preferably 1 mm or more. The maximum size of the cartridge 30 is preferably 20 mm or less in the direction orthogonal to the predetermined direction A. Further, the maximum size of the cartridge 30 is preferably 10 mm or less in the direction orthogonal to the predetermined direction A. On the other hand, the minimum size of the cartridge 30 is preferably 3 mm or more in the direction orthogonal to the predetermined direction A. Further, the minimum size of the cartridge 30 is preferably 1 mm or more in the direction orthogonal to the predetermined direction A.

The flavor source accommodating body 31 has a cylindrical portion 31B and an end wall 31C provided at at least one end of the tubular portion 31B, and forms a second flow path 30X extending along a predetermined direction A. The tubular portion 31B has an opening 35 at its downstream end for inserting the filter 33 (see FIG. 7). In the present embodiment, the tubular portion 31B has a substantially cylindrical shape, but is not limited to this, and may have an arbitrary tubular shape such as a square tubular shape. The end wall 31C has a mesh portion 32. The details of the structure of the mesh portion 32 will be described later. In the illustrated embodiment, the end wall 31C is provided only on the upstream side of the tubular portion 31B, but is not limited to this, and may be provided on the downstream side of the tubular portion 31B. That is, the end wall 31C provided with the mesh portion 32 may be provided in the opening 35 of the tubular portion 31B. Further, in the illustrated embodiment, the end wall 31C is provided so that the wall surface thereof is substantially orthogonal to the predetermined direction A (or the axial direction of the tubular portion 31B), but the end wall 31C is not limited to this and is provided in the predetermined direction A. It may be provided so as to incline with respect to it. In this case, the mesh portion 32 provided on the end wall 31C is also provided so as to be inclined with respect to the predetermined direction A.

The flavor source accommodating body 31 accommodates the flavor source 31A. The flavor source 31A that imparts flavor to the aerosol is housed in the second flow path 30X. Here, in order to secure the volume of the reservoir 21 that stores the aerosol source 21A in the cross section orthogonal to the aerosol flow path (predetermined direction A), it is preferable that the size of the first flow path 20X is small. Therefore, in the case where the cartridge 30 is housed in the outer frame body 24 having a constant cross-sectional area over the aerosol flow path (predetermined direction A), as a result, the size of the second flow path 30X is the above-mentioned first. It tends to be larger than the size of the flow path 20X.

The flavor source 31A is composed of a raw material piece that imparts flavor to the aerosol generated by the flavor aspirator 1. The lower limit of the size of the raw material piece is preferably 0.2 mm or more and 1.2 mm or less. Further, the lower limit of the size of the raw material piece is preferably 0.2 mm or more and 0.7 mm or less. The smaller the size of the raw material piece constituting the flavor source 31A, the larger the specific surface area, so that the flavor component is likely to be released from the raw material piece constituting the flavor source 31A. As the raw material piece constituting the flavor source 31A, chopped tobacco or a molded product obtained by molding the tobacco raw material into granules can be used. The flavor source 31A may be composed of plants other than tobacco (for example, mint, herbs, etc.). A fragrance such as menthol may be added to the flavor source 31A.

In the present embodiment, as shown in FIGS. 6 and 7, the flavor source accommodating body 31 is an upstream end portion (here, an end wall) of the flavor source accommodating body 31 in a cross section orthogonal to the aerosol flow path (predetermined direction A). It is preferable to have a protruding portion 31E protruding from the outer edge of 31C) to the upstream side (in the embodiment, the flow path forming body 23 or the end cap 25 side). The protrusion 31E may be continuously provided along the outer edge of the upstream end portion (here, the end wall 31C) of the flavor source accommodating body 31, and may be provided intermittently along the outer edge of the flavor source accommodating body 31. It may be provided.

In the present embodiment, it is preferable that the outer surface of the tubular portion 31B of the flavor source accommodating body 31 includes a tapered portion 31T extending from the upstream to the downstream as shown in FIGS. 6 and 7. The tapered portion 31T may be included in a part of the outer surface of the tubular portion 31B. The taper angle α of the tapered portion 31T is, for example, about 5 degrees.

In the present embodiment, as shown in FIG. 7, it is preferable that the inner surface of the tubular portion 31B of the flavor source accommodating body 31 is provided with a rib 31R extending from the upstream to the downstream along a predetermined direction A. Although not particularly limited, the number of ribs 31R is preferably 2 or more. It is preferable that the downstream end portion of the rib 31R does not reach the downstream end portion of the flavor source accommodating body 31. For example, in the predetermined direction A, the length L2 from the mesh portion 32 to the downstream end portion of the rib 31R is shorter than the length L1 from the mesh portion 32 to the downstream end portion of the flavor source accommodating body 31. In other words, in a state where the filter 33 is inserted into the flavor source container 31, it is preferable that the downstream end portion of the rib 31R contacts the filter 33 without reaching the downstream end portion of the flavor source container 31.

The flavor source container 31 can be formed of, for example, a resin. As the resin, for example, one or more resins selected from polypropylene, polyethylene terephthalate, polyethylene resin and ABS resin can be used. From the viewpoint of moldability and texture, the resin is preferably polypropylene. The flavor source container 31 can be formed by mold molding or injection molding. The tubular portion 31B and the end wall 31C may be integrally formed, or may be a separate tubular portion 31B and the end wall 31C, respectively.

Next, the end wall 31C of the cartridge 30 according to the present embodiment will be described in detail. As shown in FIG. 8, the end wall 31C of the present embodiment has a mesh portion 32 including a plurality of openings 32A. The plurality of openings 32A of the mesh portion 32 are arranged in a mesh shape, that is, in a mesh shape. As used herein, the term "mesh" is a structure including openings 32A arranged in a mesh pattern, in which only one row of openings 32A is arranged, or a distance between openings 32A adjacent to each other rather than the size of the openings 32A. Does not include a structure having a very large opening (for example, 3 times or more) and a structure having a small number of openings 32A (for example, less than 9). As shown in FIG. 8, the mesh portion 32 has an outer edge 32B. Here, the outer edge 32B of the mesh portion 32 is an edge that surrounds the plurality of openings 32A constituting the mesh portion 32 at the shortest distance.

Each of the plurality of openings 32A is not limited to the substantially rectangular shape shown in FIG. 8, and may have any shape such as a circle, an ellipse, a square, a rhombus, a hexagon, and an octagon. Each of the plurality of openings 32A may have any same shape, or may partially include any different shape. From the viewpoint of arrangement efficiency and ease of manufacture of the plurality of openings 32A, it is preferable that each of the plurality of openings 32A has a quadrangular shape. In the example shown in FIG. 8, it is preferable that the plurality of openings 32A are arranged so that the sides of the openings 32A adjacent to each other are parallel to each other. Further, the distance between the openings 32A adjacent to each other is preferably 0.15 mm or more and 0.30 mm or less. In such a case, the thickness of the mesh portion 32 is preferably 0.1 mm or more and 1 mm or less.

As shown in FIG. 8, the end wall 31C of the flavor source accommodating body 31 further has a non-mesh portion 36. The non-mesh portion 36 can be said to be a portion of the end wall 31C having no opening or a portion having a non-mesh opening. Further, in another example, instead of the non-mesh portion 36, the mesh portion having an aperture ratio (second aperture ratio) smaller than the opening ratio (first aperture ratio) of the mesh portion 32 (corresponding to the first portion). It may be (corresponding to the second part). In the present embodiment, the non-mesh portion 36 is located inside the outer edge 32B of the mesh portion 32 when viewed from the axial direction (predetermined direction A) of the tubular portion 31B. In the example shown in FIG. 8, the non-mesh portion 36 has a substantially circular outer edge 36A. Not limited to this, the shape of the outer edge 36A of the non-mesh portion 36 is arbitrary.

According to the flavor source accommodating body 31 of the cartridge 30 shown in FIG. 8, the non-mesh portion 36 is located inside the outer edge 32B of the mesh portion 32, so that the flavor source 31A housed inside is moved from the flavor source accommodating body 31. It is possible to suppress spillage and improve the strength of the end wall 31C.

In the example shown in FIG. 8, it is preferable that the non-mesh portion 36 does not come into contact with the outer edge 32B of the mesh portion 32. In this case, the non-mesh portion 36 is surrounded by the opening 32A of the mesh portion 32. As a result, the strength of the end wall 31C can be improved in a well-balanced manner as compared with the case where the non-mesh portion 36 is in contact with the outer edge 32B of the mesh portion 32. Further, the non-mesh portion 36 preferably overlaps with the center of gravity of the outer edge 32B of the mesh portion 32. As a result, the strength of the end wall 31C can be further improved in a well-balanced manner.

As shown in FIG. 8, it is preferable that the non-mesh portion 36 does not have an opening. In this case, the strength of the mesh portion 32 can be further improved as compared with the case where the non-mesh portion 36 is provided with an opening. Further, as shown in FIG. 8, only one non-mesh portion 36 may be provided inside the outer edge 32B of the mesh portion 32.

It is preferable that the outer edge 36A of the non-mesh portion 36 has a shape having distinctiveness when viewed from the axial direction (predetermined direction A) of the tubular portion 31B. In the present specification, the "shape having distinctiveness" means an arbitrary geometric shape, logo, figure, figure, character, sentence, name, etc., and the non-mesh portion 36 is referred to when the outer edge 36A is visually recognized. A recognizable shape. This makes it possible to impart designability to the end wall 31C of the flavor source accommodating body 31. Further, it is more preferable that the outer edge 36A of the non-mesh portion 36 has a geometric shape.

As shown in FIG. 7, the non-mesh portion 36 of the present embodiment can be integrally formed with the mesh portion 32 so as to fill the mesh portion 32. In other words, the non-mesh portion 36 is formed integrally with the end wall 31C. As a result, for example, the non-mesh portion 36 can be formed at the same time as the production of the flavor source accommodating body 31 by injection molding, so that the increase in the manufacturing process of the cartridge 30 due to the formation of the non-mesh portion 36 can be suppressed. .. However, the present invention is not limited to this, and the non-mesh portion 36 may be composed of a member different from the end wall 31C.

9A and 9B are cross-sectional views showing a flavor source accommodating body 31 of the cartridge 30 according to another embodiment. In the example shown in FIGS. 9A and 9B, the non-mesh portion 36 is arranged so as to cover the opening 32A without filling the opening 32A of the mesh portion 32. Specifically, in the example shown in FIG. 9A, the non-mesh portion 36 is arranged so as to cover the mesh portion 32 from the downstream side, and in the example shown in FIG. 9B, the non-mesh portion 36 has the mesh portion 32 on the upstream side. Arranged to cover from.

The non-mesh portion 36 shown in FIGS. 9A and 9B may be formed of a material different from the end wall 31C capable of covering the mesh portion 32. Specifically, for example, the non-mesh portion 36 can be formed of a liquid holding member made of a porous body such as cotton. In this case, even if the aerosol from the atomizing portion 22 that collides with the non-mesh portion 36 aggregates in the non-mesh portion 36 to generate a droplet, the droplet can be held by the non-mesh portion 36. This prevents the droplets from flowing back to the upstream side and the user from sucking the droplets. Further, by replacing the cartridge 30, the droplets held in the non-mesh portion 36 can be discarded from the flavor aspirator 1. The non-mesh portion 36 shown in FIGS. 9A and 9B may be formed of the same material as the end wall 31C. Further, the non-mesh portion 36 shown in FIG. 9A or FIG. 9B may be additionally provided on the end wall 31C in which the mesh portion 32 is filled with the non-mesh portion 36 shown in FIGS. 7 and 8.

FIG. 10 is a diagram showing a flavor source container 31 of the cartridge 30 according to another embodiment. Specifically, FIG. 10A is a plan view of the flavor source accommodating body 31 as viewed from the upstream side. Further, FIG. 10B is a cross-sectional view of the end wall 31C of the flavor source accommodating body 31 in the cross section CC shown in FIG. 10A. As shown in FIG. 10, it is preferable that the non-mesh portion 36 has an uneven surface 37 composed of a concave portion 37a and a convex portion 37b on a surface intersecting the axial direction of the tubular portion 31B, that is, an upstream surface. In this case, even if the aerosol from the atomizing portion 22 that collides with the non-mesh portion 36 aggregates in the non-mesh portion 36 to generate a droplet, the droplet can be held in the unevenness 37 (concave portion 37a). This prevents the droplets from flowing back to the upstream side and the user from sucking the droplets. Further, by replacing the cartridge 30, the droplets held in the unevenness 37 (recessed portion 37a) can be discarded from the flavor aspirator 1.

Further, as shown in FIG. 10, the unevenness 37 may define the groove 38 by the concave portion 37a and the convex portion 37b. It is preferable that the end 38a of the groove 38 is connected to at least one of the openings 32A of the mesh portion 32 when viewed from the axial direction (predetermined direction A) of the tubular portion 31B, specifically from the upstream side. In this case, the droplets held in the unevenness 37 can move in the groove 38 by the capillary action and reach the opening 32A. Droplets that reach the opening 32A can be retained in the opening 32A or absorbed by the flavor source 31A in the flavor source container 31. Therefore, the backflow of the droplet to the upstream side is further suppressed. Further, as shown in FIG. 10, the groove 38 preferably extends in parallel with the arrangement direction of the plurality of openings 32A of the mesh portion 32. In the example shown in FIG. 10, the plurality of openings 32A have a first direction (vertical direction in (A) of FIG. 10) orthogonal to the axial direction of the tubular portion 31B, an axial direction of the tubular portion 31B, and They are arranged in the second direction (left-right direction in (A) of FIG. 10) orthogonal to the first direction. Therefore, in the example shown in FIG. 10, the groove 38 extends in parallel with the first direction and the second direction.

FIG. 11 is a plan view of the non-mesh portion 36 when the flavor source accommodating body 31 according to another embodiment is viewed from the upstream side. The non-mesh portion 36 shown in FIG. 11 has an uneven portion 37 composed of a concave portion 37a and a convex portion 37b. In the illustrated embodiment, the boundary 37c between the concave portion 37a and the convex portion 37b preferably has a shape having distinctiveness when viewed from the axial direction (predetermined direction A) of the tubular portion 31B. In the illustrated example, the boundary 37c has a star shape. This makes it possible to impart designability to the end wall 31C of the flavor source accommodating body 31. In the example shown in FIG. 11, the convex portion 37b is provided around the concave portion 37a, but the present invention is not limited to this, and the concave portion 37a may be provided around the convex portion 37b.

The non-mesh portion 36 shown in FIG. 11 has a printed portion 39 having distinctiveness on a surface intersecting the axial direction of the tubular portion 31B, that is, a surface on the upstream side. In the illustrated example, a star-shaped figure is printed on the non-mesh portion 36 as the printing portion 39. The printing unit 39 can be formed by a known printing technique capable of printing on a resin or the like, for example, ink printing or the like. This makes it possible to impart designability to the end wall 31C of the flavor source accommodating body 31.
