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 designated by the same reference numerals and duplicate description will be omitted. The flavor aspirator according to the present embodiment is used together with a rod-shaped flavor generating article.

FIG. 1A is an overall perspective view of the flavor aspirator according to the present embodiment. FIG. 1B is an overall perspective view of the flavor aspirator according to the present embodiment in a state where the flavor generating article is held. The flavor aspirator 10 according to the present embodiment is configured to generate an aerosol containing an aerosol by heating, for example, a flavor generating article 110 having a flavor source containing an aerosol source.

As shown in FIGS. 1A and 1B, the flavor aspirator 10 includes a top housing 11A, a bottom housing 11B, a cover 12, a switch 13, a lid 14, a first vent 15, a cap 16, and the like. Has. The top housing 11A and the bottom housing 11B are connected to each other to form the outermost outer housing 11 of the flavor aspirator 10. The outer housing 11 is sized to fit in the user's hand.

The cover. Thereby, the lid portion 14 can allow or limit the access of the flavor generating article 110 to the inside of the flavor aspirator 10 (the opening 61 of the insertion guide member 17 shown in FIG. 4).

The switch 13 is used to switch the operation of the flavor aspirator 10 on and off. For example, by operating the switch 13 with the flavor generating article 110 inserted in the opening 12a as shown in FIG. 1B, power is supplied to a heating member (not shown) from a power source (not shown), and the flavor generating article 110 is supplied. Can be heated without burning. When the flavor generating article 110 is heated, the aerosol evaporates from the aerosol source contained in the flavor generating article 110, and the flavor of the flavor source is incorporated into the aerosol. The user can suck the aerosol containing the flavor by sucking the portion (the portion shown in FIG. 1B) protruding from the flavor suction device 10 of the flavor generating article 110.

The first vent 15 is a vent for introducing air into the heating assembly 41 (see FIG. 3), which is stored in the internal space of the outer housing 11. The cap 16 is detachably configured on the bottom housing 11B. By attaching the cap 16 to the bottom housing 11B, a first vent 15 is formed between the bottom housing 11B and the cap 16. The cap 16 may have, for example, a through hole or notch (not shown). In the present specification, the longitudinal direction of the flavor aspirator 10 means the direction in which the flavor generating article 110 is inserted into the opening 12a. Further, in the flavor aspirator 10 of the present specification, the side where air flows in (for example, the first vent 15 side) is the upstream side, and the side where air flows out (for example, the opening 12a side) is the downstream side.

The filling 111 of the flavor generating article 110 in the present embodiment may contain tobacco chopped as a flavor source. The material for chopping tobacco is not particularly limited, and known materials such as lamina and middle bone can be used. The range of the content of the filling material 111 in the flavor generating article 110 is, for example, 200 mg to 400 mg, preferably 250 mg to 320 mg in the case of a circumference of 22 mm and a length of 20 mm. The water content of the packing 111 is, for example, 8% by weight to 18% by weight, preferably 10% by weight to 16% by weight. With such a water content, the occurrence of winding stains is suppressed, and the hoisting suitability of the base material portion 110A during production is improved. There are no particular restrictions on the size of the tobacco nicks used as the filler 111 or the method for preparing the nicks. For example, dried tobacco leaves may be chopped to a width of 0.8 mm to 1.2 mm. Further, dried tobacco leaves may be crushed and homogenized so that the average particle size is about 20 μm to 200 μm, processed into a sheet, and chopped into a width of 0.8 mm to 1.2 mm. .. Further, the sheet processed product which has been gathered without being carved may be used as the filling material 111. Further, the filling material 111 may contain one kind or two or more kinds of fragrances. The type of the flavor is not particularly limited, but menthol is preferable from the viewpoint of imparting a good taste.

The paper containing such a filler exhibits a preferable white-based bright color from the viewpoint of appearance used as a rolling paper for the flavor-generating article 110, and can permanently maintain whiteness. By containing a large amount of such a filler, for example, the ISO whiteness of the wrapping paper can be increased to 83% or more. Further, from the practical viewpoint of using as a wrapping paper for the flavor-generating article 110, the first wrapping paper 112 and the second wrapping paper 113 preferably have a tensile strength of 8N / 15 mm or more. This tensile strength can be increased by reducing the content of the filler. Specifically, the tensile strength can be increased by reducing the content of the filler from the upper limit of the content of the filler shown in the range of each basis weight illustrated above.

Next, the internal structure of the flavor aspirator 10 shown in FIGS. 1A and 1B will be described. FIG. 3 is a cross-sectional view taken along the line 3-3 shown in FIG. 1A. As shown in FIG. 3, the flavor aspirator 10 has a power supply unit 20, a circuit unit 30, and a heating unit 40 in the internal spaces of the outer housing 11 and the inner housing 18.

The circuit unit 30 includes a first circuit board 31, a second circuit board 32, and a third circuit board 33, which are electrically connected to each other. The first circuit board 31 is arranged so as to extend in the longitudinal direction adjacent to one surface of the rectangular power supply 21 as shown in the figure, for example. A partition wall 34 is provided between the first circuit board 31 and the heating unit 40, whereby at least a part of the area accommodating the power supply unit 20 and the first circuit board 31 is partitioned. The partition wall 34 may be provided with a notch, a through hole, or the like for fluid communication between the space on the power supply unit 20 side and the space on the heating unit 40 side.

The second circuit board 32 is arranged inside the top housing 11A between the cover 12 and the power supply unit 20, and extends in a direction orthogonal to the extending direction of the first circuit board 31. The switch 13 is arranged adjacent to the second circuit board 32. When the user presses the switch 13, a part of the switch 13 may come into contact with the second circuit board 32. The third circuit board 33 is arranged so as to extend in the longitudinal direction in the space formed on the opposite side of the opening 12a with respect to the heating portion 40.

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 housing 11B so that its main surface is inclined with respect to the longitudinal direction. As a result, the main surface of the third circuit board 33 can be enlarged, and the space inside the bottom housing 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 and the like, and can control the supply of electric power from the power supply unit 20 to the heating unit 40. As a result, the first circuit board 31, the second circuit board 32, and the third circuit board 33 can control the heating of the flavor-generating article 110 by the heating unit 40.

The power supply unit 20 has a power supply 21 that is electrically connected to the first circuit board 31, the second circuit board 32, and the third circuit board 33. The power source 21 can be, for example, a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the heating unit 40 via at least one of the first circuit board 31, the second circuit board 32, and the third circuit board 33. As a result, the power source 21 can supply electric power to the heating unit 40 so as to appropriately heat the flavor generating article 110. Further, as shown in the figure, the power supply 21 is arranged in parallel with the heating unit 40. As a result, even if the size of the power supply 21 is increased, it is possible to prevent the length of the flavor aspirator 10 from becoming longer in the longitudinal direction.

Further, the flavor aspirator 10 has a terminal 22 that can be connected to an external power source. The terminal 22 can be connected to a cable such as a micro USB. When the power supply 21 is a rechargeable battery, by connecting an external power supply to the terminal 22, a current can flow from the external power supply to the power supply 21 to charge the power supply 21. Further, by connecting a data transmission cable such as a micro USB to the terminal 22, data related to the operation of the flavor aspirator 10 may be transmitted to an external device.

As shown in the figure, the heating unit 40 has a heating assembly 41 extending in the longitudinal direction, a bottom cap 50 having an L-shaped cross section, and a substantially tubular insertion guide member 17. The heating assembly 41 includes a plurality of tubular members, and forms a tubular body as a whole. The heating assembly 41 is configured to accommodate a part of the flavor generating article 110 inside, and has a function of defining a flow path of air supplied to the flavor generating article 110 and a function of heating the flavor generating article 110 from the outer circumference. Have.

The bottom housing 11B is formed with a first vent 15 and a second vent 19 for allowing air to flow into the heating assembly 41. Specifically, the first vent 15 penetrates the bottom cap 50 and communicates fluidly with the upstream end of the flow path leading to the heating assembly 41. That is, the first vent 15 communicates fluidly with the upstream end of the heating assembly 41 via the through flow path of the bottom cap 50. The second vent 19 communicates fluidly with the upstream end of the air flow path 19A formed between the outer housing 11 and the inner housing 18. Further, since the downstream end of the air flow path 19A communicates fluid with the upstream end of the flow path penetrating the bottom cap 50, the second vent 19 is finally connected to the heating assembly 41 as well as the first vent 15. Fluid communication.

The downstream end of the heating assembly 41 penetrates the insertion guide member 17 and communicates fluidly with the upstream end of the flow path leading to the opening 12a shown in FIG. 1B. The insertion guide member 17 is, for example, a member formed of a resin material and provided between the cover 12 having the opening 12a and the downstream end of the heating assembly 41. When the flavor generating article 110 is inserted into the inside of the flavor aspirator 10 through the opening 12a of the cover 12 as shown in FIG. 1B, the flavor generating article 110 passes through the insertion guide member 17, and a part of the flavor generating article 110 is part of the heating assembly 41. Placed inside. Therefore, the insertion guide member 17 is preferably formed so that the opening on the cover 12 side is larger than the size of the opening on the downstream side of the heating assembly 41. As a result, the flavor generating article 110 can be easily inserted into the insertion guide member 17 through the opening 12a.

As shown in FIG. 1B, in a state where the flavor generating article 110 is inserted into the flavor aspirator 10 through the opening 12a, a portion of the flavor generating article 110 protruding from the flavor aspirator 10, that is, FIG. When sucked from the filter portion 115, air flows into the inside of the heating assembly 41 from the first vent 15 and the second vent 19. The inflowing air passes through the inside of the heating assembly 41 and reaches the user's mouth together with the aerosol generated from the flavor generating article 110. Therefore, the side of the heating assembly 41 near the first vent 15 and the second vent 19 (the side closer to the bottom cap 50) is the upstream side, and the side closer to the opening 12a of the heating assembly 41 (closer to the insertion guide member 17). Side) is the downstream side.

Next, the configuration of the heating unit 40 shown in FIG. 3 will be described. FIG. 4 is a cross-sectional view of the heating unit 40. As shown in FIG. 4, the heating unit 40 includes a heating assembly 41, a bottom cap 50, and an insertion guide member 17. The heating assembly 41 includes a cup-shaped container 42 forming a chamber for accommodating the flavor generating article 110, a heating member 43, a heat shrink tube 44, and a heat insulating member 45.

The container 42 has a first opening 42a into which the flavor generating article 110 can be inserted at one end and a second opening 42b forming an air inlet at the other end so that the flavor generating article 110 can be accommodated. To. In the present embodiment, the container 42 has an inner wall configured to come into contact with at least a part of the outer wall of the flavor generating article 110 inserted through the first opening 42a. Further, the container 42 has a bottom wall 42d against which the tip of the flavor generating article 110 inserted through the first opening 42a is abutted. The second opening 42b is a through hole formed in the bottom wall 42d of the container 42. The second opening 42b is located on the upstream side of the air flow, and the first opening 42a is located on the downstream side. Further, a boss 42c configured to press the outer wall of the inserted flavor generating article 110 inward in the radial direction is formed on the inner peripheral surface of the container 42 on the side of the first opening 42a.

The heating member 43 can be a flexible film heater formed by sandwiching a heat generating resistor between, for example, two films such as PI (polyimide). The heating member 43 is arranged so as to come into contact with the container 42. Specifically, in the illustrated example, the heating member 43 is arranged on the outer peripheral surface of the container 42, and the inner surface of the heating member 43 is in close contact with the outer surface of the container 42. Since the heating member 43 is arranged along the outer peripheral surface of the container 42, it is deformed into a substantially tubular shape as a whole.

The heat-shrinkable tube 44 has a tubular shape, and the heating member 43 maintains a state of being in close contact with the container 42. Specifically, the heat-shrinkable tube 44 is heat-shrinked by applying heat while being arranged on the outer peripheral side of the heating member 43, whereby the heating member 43 is pressed against the container 42. Stress 43. Here, the heat-shrinkable tube 44 covers a part of the downstream side of the bottom cap 50 and is heat-shrinked, so that the container 42 and the bottom cap 50 can be brought into close contact with each other.

The heat insulating member 45 is a tubular member having a double tube structure, and is arranged radially outwardly at a predetermined interval from the heat shrink tube 44. The heat insulating member 45 has an inner tubular member 45a, an outer tubular member 45b, a first annular member 45c, and a second annular member 45d. The inner tubular member 45a and the outer tubular member 45b are arranged side by side in the radial direction of the inserted flavor generating article 110. The first annular member 45c is arranged on the downstream side of the inner tubular member 45a and the outer tubular member 45b, and the second annular member 45d is arranged on the upstream side of the inner tubular member 45a and the outer tubular member 45b. For example, the heat insulating member 45 can be a vacuum heat insulating material having decompressed air or vacuum inside the double tube structure. Specifically, by depressurizing the space formed by the inner tubular member 45a and the outer tubular member 45b and the first annular member 45c and the second annular member 45d, the heat generated from the heating member 43 is generated by the heating assembly. It becomes difficult to be transmitted to the outside of 41. However, the structure of the heat insulating member 45 is not limited to the above, and the heat insulating member 45 in the drawing may be omitted.

The bottom cap 50 is a member forming a pipe having a downstream end 50a that engages with the upstream end (end on the second opening 42b side) of the container 42 and an upstream end 50b on the opposite side of the downstream end 50a. .. The bottom cap 50 forms an internal flow path for introducing air toward the second opening 42b of the container 42. The bottom cap 50 shown in FIG. 4 forms an internal flow path curved in an L shape. Further, the upstream end 50b of the bottom cap 50 is arranged close to or adjacent to the first vent 15 and the air flow path 19A shown in FIG.

The upstream end of the insertion guide member 17 (the end on the side of the first opening 42a) surrounds the outer circumference of the downstream end of the container 42, and a predetermined gap is provided between the insertion guide member 17 and the container 42. .. That is, the upstream end of the insertion guide member 17 has an inner diameter larger than the outer diameter of the downstream end of the container 42, which can accommodate the downstream end of the container 42.

The opening 61 communicates with the opening 12a of the cover 12 so that the flavor generating article 110 can be inserted. The inner peripheral surface 62 is configured to surround the outer periphery of the flavor generating article 110 inserted through the opening 61. Further, the inner peripheral surface 62 has a non-protruding portion 62a formed adjacent to the opening 61 side of the protruding portion 63 and the opposite side of the opening 61, and including a region separated from the outer peripheral surface of the inserted flavor generating article 110. ..
