Thereby, the lid 14 can allow or restrict the fragrance-generating article 110 from entering the fragrance inhaler 10.

The switch 13 is used to switch the action of the flavor inhaler 10 on (on) and off (off). For example, as shown in Figure 1B, the user operates the switch 13 in a state where the fragrance generating article 110 is inserted into the opening 12a, so that power can be supplied from a power source not shown in the figure. The heating member shown does not burn the fragrance generating article 110 and heats it. When the fragrance-generating article 110 is heated, the user can taste the portion of the fragrance-generating article 110 protruding from the fragrance inhaler 10 (the portion shown in FIG. 1B), thereby inhaling the fragrance.

The second air inlet 15 is a vent for introducing air into the heating assembly 41 (refer to FIG. 3) stored in the internal space of the outer casing 11. The cover 16 is configured to be detachable from the bottom case 11B. The cover 16 is mounted on the bottom case 11B, and a second air inlet 15 is formed between the bottom case 11B and the cover 16. The cover 16 may have, for example, a through hole or a notch not shown. In addition, in this specification, the longitudinal direction of the flavor inhaler 10 refers to the direction in which the flavor generating article 110 is inserted into the opening 12a. In addition, in the flavor inhaler 10 of this specification, the side where fluid such as air flows in (for example, the second air inlet 15 side) is the upstream side, and the side where the fluid flows out (for example, the opening 12a side) is the downstream side.

In this embodiment, the filling 111 of the fragrance generating article 110 may contain an aerosol source heated at a predetermined temperature to generate aerosol. The type of aerosol source is not particularly limited, and extracts from various natural products and/or these constituent components can be selected according to the application. In terms of aerosol sources, for example, there are glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. The content of the aerogel source in the filling 111 is not particularly limited, as it can fully produce aerosol and impart a good taste fragrance From the viewpoint of, it is usually 5% by weight or more, preferably 10% by weight or more, and in addition, it is usually 50% by weight or less, preferably 20% by weight or less.

The filling 111 of the flavor generating article 110 of this embodiment may contain tobacco rods as a flavor source. The material of the tobacco rod is not particularly limited, and known ones such as lamina or tobacco bone can be used. The range of the content of the filler 111 in the fragrance generating article 110 is, when the circumference is 22 mm and the length is 20 mm, for example, 200 mg to 400 mg, and preferably 250 mg to 320 mg. The moisture content of the filling 111 is, for example, 8% to 18% by weight, and preferably 10% to 16% by weight. When it is such a moisture content, the occurrence of winding contamination can be suppressed, and the appropriateness of the winding during the production of the base material portion 110A can be improved. There are no particular restrictions on the size of the tobacco rod used as the filler 111 or its production method. For example, what is obtained by subdividing dried tobacco leaves into widths of 0.8 mm to 1.2 mm can be used. In addition, it is also possible to use what is obtained by pulverizing dried tobacco leaves and averaging to an average particle diameter of about 20 μm to 200 μm for sheet processing, and subdivided into pieces having a width of 0.8 mm to 1.2 mm. Furthermore, with regard to the above-mentioned sheet-processed product, it is also possible to use a product obtained by gathering processing without being subdivided as the filling material 111. In addition, the filling 111 may contain one or more flavors. The kind of the fragrance is not particularly limited, but from the viewpoint of imparting a good tasting fragrance, menthol is preferred.

In this embodiment, the first roll paper 112 and the second roll paper 113 of the fragrance generating article 110 can be made of base paper with a basis weight of, for example, 20 gsm to 65 gsm, preferably 25 gsm to 45 gsm.

The paper containing such a filler exhibits a bright white color from the viewpoint of the appearance of being used as a roll paper of the fragrance generating article 110, and can be kept white constantly. By containing more such fillers, for example, the ISO brightness of the roll paper can be over 83%. In addition, from the practical point of view of being used as the roll paper of the fragrance generating article 110, the first roll paper 112 and the second roll paper 113 preferably have a tensile strength of 8N/15mm or more. This tensile strength can be increased by reducing the filler content. Specifically, by reducing the content of the filler more than the upper limit of the content of the filler shown in the above-exemplified range of each basis weight, the tensile strength can be improved.

Next, the internal structure of the flavor inhaler 10 shown in FIGS. 1A and 1B will be described. Fig. 3 is a cross-sectional view of arrow 3-3 shown in Fig. 1A. As shown in FIG. 3, the flavor inhaler 10 has an inner housing 18 provided inside the outer housing 11. The inner space of the inner casing 18 is provided with a power supply unit 20, a circuit unit 30 and a heating device 40.

The circuit unit 30 has a first circuit board 31, a second circuit board 32, and a third circuit board 33 that are electrically connected to each other. The first circuit board 31 is arranged so as to be adjacent to one surface of the substantially columnar power supply 21 and to extend in the longitudinal direction, for example. A partition wall 34 is provided between the first circuit board 31 and the heating device 40, thereby dividing and accommodating the power supply unit 20 and the first circuit board At least part of the area of 31. The partition wall 34 may be provided with a notch or a through hole for fluid communication between the space on the power supply unit 20 side and the space on the heating device 40 side.

The second circuit board 32 is arranged between the cover 12 and the power supply unit 20 inside the top case 11A, and extends in a direction orthogonal to the extending direction of the first circuit board 31. The switch 13 is arranged so as to be adjacent to the second circuit board 32. When the user presses the switch 13, a part of the switch 13 will contact the second circuit board 32. The third circuit board 33 is arranged in a space formed on the opposite side of the opening 12a (refer to FIG. 1B) with respect to the heating device 40 so as to extend in the longitudinal direction.

The third circuit board 33 has a main surface on which various electronic components are mounted. For example, the third circuit board 33 may be arranged in the bottom case 11B in such a manner that the main surface thereof is inclined with respect to the longitudinal direction. Thereby, the main surface of the third circuit board 33 can be enlarged, and the space in the bottom case 11B can be effectively utilized.

The first circuit board 31, the second circuit board 32, and the third circuit board 33 include, for example, a microprocessor (microprocessor) and the like, and can control the power supply from the power supply unit 20 to the heating device 40. Thereby, the first circuit board 31, the second circuit board 32, and the third circuit board 33 can control the heating of the fragrance generating article 110 by the heating device 40.

The power supply unit 20 has a power supply 21 electrically connected to the first circuit board 31, the second circuit board 32, and the third circuit board 33. The power source 21 may be, for example, a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the heating device 40 via at least one of the first circuit board 31, the second circuit board 32, and the third circuit board 33. Thereby, the power supply 21 can supply electric power to the heating device 40 to appropriately heat the fragrance generating article 110. In addition, as shown in the figure, the power supply 21 and the heating device 40 are connected in parallel in a direction orthogonal to the longitudinal direction. 地Configuration. Thereby, even if the size of the power source 21 is increased, the length of the flavor inhaler 10 in the longitudinal direction can be suppressed from increasing.

In addition, the flavor inhaler 10 has a terminal 22 that can be connected to an external power source. The terminal 22 can be connected to, for example, a cable such as a micro USB (USB (Universal Serial Bus)). When the power source 21 is a rechargeable battery, by connecting an external power source to the terminal 22, Electric current flows from an external power source to the power source 21 to charge the power source 21. In addition, it can also be set to transmit data related to the operation of the fragrance inhaler 10 by connecting a data transmission cable such as a micro USB to the terminal 22 To an external device.

As shown in the figure, the heating device 40 includes: a heating element 41 extending in the longitudinal direction; an elbow 50 having a substantially L-shaped cross section; and an insertion guide member 17 having a substantially cylindrical shape. The heating assembly 41 includes a plurality of cylindrical members, which constitute a cylindrical body as a whole. The heating element 41 constitutes a heating chamber inside which can accommodate a part of the fragrance generating article 110, and has the function of dividing the flow path of the air to be supplied to the fragrance generating article 110, and from the periphery from the opening 12a (refer to Figure 1B) ) The function of heating the inserted fragrance generating article 110. The insertion guide member 17 is formed of, for example, a resin material, and is provided between the cover 12 having an opening 12 a (refer to FIG. 1B) and the downstream end of the heating element 41 to guide the fragrance generating article 110 to be inserted into the heating element 41.

The elbow 50 is formed of, for example, a resin material. The elbow 50 has a first end 50a and a second end 50b. The first end 50a of the elbow 50 is connected to the end on the upstream side of the heating element 41, that is, the end on the opposite side to the opening 12a (refer to FIG. 1B). The second end 50b is formed with an opening at an angle with respect to the longitudinal direction of the heating chamber of the heating element 41. Specifically, as described above, in this embodiment, the elbow 50 is L-shaped, so the second end 50b is facing in a direction substantially orthogonal to the longitudinal direction of the heating chamber of the heating element 41 Open up. As a result, the second end 50b is positioned so as to face the cover 16 mounted on the bottom case 11B. That is, the cover 16 covers at least a part of the second end 50b of the elbow 50 in an openable and closable manner. The elbow 50 introduces the air supplied from the second end 50b into the heating chamber of the heating element 41 through the first end 50a. In addition, the elbow 50 is not limited to the L-shape, and the second end 50b may be bent at an arbitrary angle so that the second end 50b faces the side surface of the outer housing 11.

As shown in the figure, in a state in which the cover 16 is mounted on the outer housing 11, a predetermined space A1 is formed between the cover 16 and the inner housing 18. The second end 50b of the elbow 50 is in communication with the space A1. When the cover 16 is removed from the outer shell 11, the inside of the elbow 50 can be entered from the second end 50b. Therefore, the cover 16 is removed from the outer case 11, and the inside of the elbow 50 can be cleaned with, for example, an arbitrary cleaning tool. In addition, in the longitudinal direction, in the corner portion (the corner portion on the bottom side) on the distal side with respect to the heating element 41 of the elbow 50, there is a problem that solid or liquid generated by the action of the heating chamber is accumulated. possibility. Therefore, as shown in the figure, it is preferable to make a bevel angle on the inner surface of the elbow 50 that is on the distal side with respect to the heating element 41 in the longitudinal direction. In this way, any cleaning tool will be easier to touch the corner of the elbow 50.

In the bottom case 11B, a first air inlet 19 and a second air inlet 15 for introducing air into the heating element 41 are formed. The first air inlet 19 is formed on the bottom side of the bottom case 11B. Specifically, in this embodiment, the first air inlet 19 is formed on the inclined surface of the bottom case 11B. In other words, the first air inlet 19 is formed on the surface of the bottom shell 11B having an angle with respect to the longitudinal direction of the heating chamber of the heating element 41 (the longitudinal direction of the fragrance generating article 110 inserted in the heating chamber). The first air inlet 19 is not covered by a cover or the like, and is always in an open state.

In addition, the second air inlet 15 is formed on the side surface of the bottom case 11B. Therefore, the first air inlet 19 is arranged to be separated from the second air inlet 15 toward the extending direction of the heating chamber of the heating element 41. More specifically, the first air inlet 19 is provided on the far side of the second air inlet 15 with respect to the opening 12a (refer to FIG. 1B). In addition, in this embodiment, the second end 50b of the elbow 50 is located between the first air inlet 19 and the second air inlet 15 in the longitudinal direction. Furthermore, the second air inlet 15 is located closer to the end side than the second end 50b of the elbow 50 with respect to the opening 12a.

Between the outer casing 11 and the inner casing 18, a flow path 19A communicating with the first air inlet 19 is formed. As shown in the figure, the flow path 19A connects the first air inlet 19 and the space A1. Therefore, the air flowing in from the first air inlet 19 is supplied to the heating chamber of the heating element 41 through the flow path 19A, the space A1 and the elbow 50. That is, the first air flow path connecting the first air inlet 19 and the heating chamber of the heating element 41 is formed by the flow path 19A, the space A1 and the internal space of the elbow 50.

As shown in the figure, the heating element 41 extends from the opening 12a to the substantially central portion in the longitudinal direction of the flavor inhaler 10, and from the central portion in the longitudinal direction to the bottom, there is a space (arrangement) where the heating element 41 is not present. There is a space for the third circuit board 33). The flow path 19A is provided so as not to pass through the periphery of the heating element 41 from the first air inlet 19 to the space A1. In other words, the flow path 19A is positioned so as to be separated from the heating chamber in the extending direction of the heating chamber of the heating element 41. Therefore, it is suppressed that the air passing through the flow path 19A is affected by the heating element 41.

The second air inlet 15 is an air vent formed in the gap between the cover 16 and the outer housing 11 and communicates with the space A1. Therefore, the air flowing in from the second air inlet 15 is supplied to the heating chamber of the heating element 41 through the space A1 and the elbow 50. That is, with the space A1 and the curve The inner space of the tube 50 forms a second air flow path connecting the second air inlet 15 and the heating chamber of the heating assembly 41.

The first air flow path and the second air flow path merge between the heating chamber of the heating assembly 41 and the first air inlet 19 and the second air inlet 15. Specifically, in this embodiment, the first air flow path and the second air flow path merge in the space A1. Therefore, the air flowing in from the first air inlet 19 is mixed with the air flowing in from the second air inlet 15 in the space A1, and then passes through the elbow 50 to reach the heating chamber. In other words, the air flowing in from the first air inlet 19 and the second air inlet 15 passes through the heating chamber and is used to transport the aerosol. The supply ratio of the air flowing into the heating chamber from the first air inlet 19 to the air flowing into the heating chamber from the second air inlet 15 is preferably 1:2 to 1:10, more preferably 1:3 To 1:5. By setting the amount of air flowing in from the first air inlet 19 to be a certain amount or less, it is possible to prevent dust and the like in the atmosphere from being mixed into the air flow path. In addition, the flow path length of the first air flow path is longer than the flow path length of the second air flow path.

As shown in Fig. 1B, when the fragrance generating article 110 is inserted into the fragrance inhaler 10 from the opening 12a of the cover 12, a part of the fragrance generating article 110 is arranged on the heating unit by inserting the guide member 17 41's interior. Therefore, the insertion guide member 17 is preferably formed such that the opening on the side of the cover 12 is larger than the opening on the side of the heating element 41. Thereby, it is easy to insert the fragrance generating article 110 from the opening 12a into the insertion guide member 17.

As shown in Figure 1B, in a state in which the fragrance-generating article 110 is inserted into the fragrance inhaler 10 from the opening 12a, when the user inhales from the portion of the fragrance-generating article 110 protruding from the fragrance inhaler 10, it is also That is, when the filter portion 115 shown in FIG. 2 is sucked, air flows into the heating element 41 from the first air inlet 19 and the second air inlet 15. Inflow The air passes through the inside of the heating assembly 41 and reaches the mouth of the user together with the aerosol generated from the fragrance generating article 110.

In the flavor inhaler 10 of this embodiment, when the flavor generating article 110 is heated by the heating chamber of the heating element 41, solids such as tobacco rods heated from the flavor generating article 110 will be generated or evaporated. Liquid formed by condensation of aerogel source. Such solid or liquid will reach the space A1 from the heating element 41 through the elbow 50. As described above, the space A1 communicates with the first air inlet 19 via the flow path 19A. In addition, when the fragrance inhaler 10 is used, the first air inlet 19 is located below the direction of gravity. Therefore, when the solid or fluid reaching the space A1 flows into the flow path 19A, it may move downward in the direction of gravity, and the solid or liquid may reach the outside of the outer casing 11 from the first air inlet 19. Therefore, the flavor inhaler 10 of this embodiment has a suppressing member 60 that suppresses the above-mentioned solid or liquid from reaching the first air inlet 19 from the elbow 50. The restraining member 60 is arranged on the first air flow path between the heating chamber of the heating assembly 41 and the first air inlet. Specifically, in this embodiment, the restraining member 60 is provided near the second end 50b of the elbow 50.

As shown in the figure, the inner housing 18 has a rim 18B that partitions the space A1 together with the cover 16 shown in FIG. 3 and the like, and a surface 18D of the inner housing 18 surrounded by the rim 18B. The edge portion 18B of this embodiment has a substantially circular arc shape along the short side and a substantially linear shape along the long side, and protrudes from the surface of the inner housing 18 toward the cover 16. In addition, the inner housing 18 has a pair of edge portions 18A that partition the flow path 19A together with the outer housing 11. The edge 18A extends from the edge 18B to the vicinity of the first air inlet 19, and is configured to guide the air flowing in from the first air inlet 19 to the space A1.

As shown in the figure, the inner housing 18 has an opening 18C communicating with the opening of the second end 50b of the elbow 50. In this embodiment, the restraining member 60 is provided around the opening 18C of the inner casing 18. The restraining member 60 has: an arc-shaped convex portion 60A that is located on the side of the first air inlet 19 of the opening portion 18C along the opening shape of the opening portion 18C; The portion 60A extends toward the second air inlet 15 side. Both the arc-shaped convex portion 60A and the linear convex portion 60B protrude from the surface 18D of the inner housing 18 toward the cover 16. That is, at least a part of the restraining member 60 (in the example shown in the figure is the arc-shaped convex portion 60A) is located in the longitudinal direction of the heating chamber of the heating element 41, and is located on the side of the curved pipe 50 with respect to the opening 12a. The second end 50b is farther away. In the example shown in the figure, the linear convex portion 60B extends from the opening 18C toward the second air inlet 15 side. Therefore, the restraining member 60 surrounds the opening 18C and the periphery of the second end 50b of the elbow 50, and opens the opening 12a side (upper side in the figure) of the second end 50b.

In this embodiment, the air flows from the first air inlet 19 toward the second end 50b, and the air is divided into two paths by the arc-shaped convex portion 60A. However, it is not limited to this, and the suppression member 60 can also be comprised so that the air from the 1st air inlet 19 toward the 2nd end part 50b may not divide into two paths. Specifically, for example, by joining either one of the pair of linear convex portions 60B to the edge portion 18B, the flow of air can be blocked, and the flow of air can be made one side. In addition, instead of the arc-shaped convex portion 60A, a convex portion extending in the lateral direction is provided in FIG. 4, and one end of the convex portion is joined to the edge portion 18B to block the flow of air. This allows air to flow into the second end 50b of the elbow 50 from the other end side of the convex portion.

The air flowing into the space A1 from the first air inlet 19 through the flow path 19A between the pair of edge portions 18A collides with the arc-shaped convex portion 60A, and follows the arc-shaped convex portion 60A and the linear convex portion 60B. Moves toward the second air inlet 15 side, and flows into the opening 18C and the first of the elbow 50 Two ends 50b. That is, the air flowing in from the first air inlet 19 bypasses the restraining member 60 and flows into the inside of the elbow 50. In other words, the air flowing in from the first air inlet 19 flows into the inside of the elbow 50 from the open portion on the side of the opening 12 a of the restraining member 60.

In this embodiment, although the restraining member 60 is provided in the inner housing 18, it is not limited to this. The restraining member 60 may also be provided, for example, on the cover 16 to restrain the solid or liquid generated by the heating chamber from reaching the first air inlet 19 from the elbow 50.

In summary, the flavor inhaler 10 of this embodiment has: a first air inlet 19; and a second air inlet 15, which is separated from the first air inlet 19 in the longitudinal direction. When using the flavor inhaler 10 of this embodiment, the user holds the side surface of the outer casing 11. At this time, when the user's hand covers a part of the second air inlet 15, the ventilation resistance of the second air flow path through which the air flowing in from the second air inlet 15 passes becomes larger. According to this embodiment, even when a part of the second air inlet 15 is covered by the user's hand, a stable amount of air can be supplied from the first air inlet 19 to the heating element 41. In addition, depending on how the user holds the fragrance inhaler 10, a part of the first air inlet 19 may also be covered. In this case, even if the ventilation resistance of the first air flow path through which air flows in from the first air inlet 19 increases, a stable amount of air can be supplied to the heating element 41 from the second air inlet 15.

In addition, the flavor inhaler 10 of this embodiment has a restraining member 60, so that solids or liquids generated due to the effect of the heating chamber can be restrained from reaching the first air inlet 19 from the elbow 50. In this embodiment, the fragrance generating article 110 is described as a stick, but it is not limited to this. For example, a cartridge containing a fragrance source and aerosol source inside a capsule may also be used. Cartridge (cartridge, also known as smoke bomb).

Furthermore, in this embodiment, the second end 50b of the elbow 50 can be directed to the side of the outer casing 11, thereby relatively shortening the distance between the opening of the second end 50b and the outer casing 11. As a result, it is easy to enter the inside of the elbow 50 from the opening of the second end 50b, and the inside of the elbow 50 can be easily maintained.
