BEST MODE FOR CARRYING OUT THE INVENTION 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 denoted by the same reference numerals, and duplicate descriptions are omitted. The flavor inhaler according to this embodiment is used together with a rod-shaped flavor generating article.

FIG. 1A is an overall perspective view of the flavor inhaler according to this embodiment. FIG. 1B is an overall perspective view of the flavor inhaler according to the present embodiment holding a flavor generating article. The flavor inhaler 10 according to this embodiment is configured to generate a flavor-containing aerosol, for example, by heating a flavor-generating article 110 having a flavor source that includes the aerosol source.

As shown in FIGS. 1A and 1B, the flavor inhaler 10 includes a top housing 11A, a bottom housing 11B, a cover 12, a switch 13, a lid portion 14, a first vent 15, a cap 16, have The top housing 11A and the bottom housing 11B constitute the outermost outer housing 11 of the flavor inhaler 10 by being connected to each other. The outer housing 11 is sized to fit in the user's hand. When the user uses the flavor inhaler 10, the user can hold the flavor inhaler 10 by hand and inhale the flavor.

The top housing 11A has an opening (not shown), and the cover 12 is coupled to the top housing 11A so as to close the opening. As shown in FIG. 1B, cover 12 has an opening 12a into which flavor generating article 110 can be inserted. The lid portion 14 is configured to open and close the opening 12 a of the cover 12 . Specifically, the lid portion 14 is attached to the cover 12 and is configured to be movable along the surface of the cover 12 between a first position for closing the opening 12a and a second position for opening the opening 12a. be. Thereby, the lid part 14 can permit or restrict the access of the flavor generating article 110 to the inside of the flavor inhaler 10 (the opening 61 of the insertion guide member 17 shown in FIG. 4).

A switch 13 is used to switch the operation of the flavor inhaler 10 on and off. For example, the user operates the switch 13 with the flavor generating article 110 inserted into the opening 12a as shown in FIG. 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 aerosol incorporates the flavor of the flavor source. The user can inhale the flavor-containing aerosol by inhaling the portion of the flavor-generating article 110 protruding from the flavor inhaler 10 (the portion illustrated in FIG. 1B).

The first vent 15 is a vent for introducing air into the interior of the heating assembly 41 (see FIG. 3) housed in the inner space of the outer housing 11 . The cap 16 is detachably attached to the bottom housing 11B. A first vent 15 is formed between the bottom housing 11B and the cap 16 by attaching the cap 16 to the bottom housing 11B. The cap 16 may have, for example, through holes or notches (not shown). 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 from which air flows in (for example, the first vent 15 side) is defined as the upstream side, and the side from which air flows out (for example, the opening 12a side) is defined as the downstream side.

Next, the configuration of the flavor generating article 110 used in the flavor inhaler 10 according to this embodiment will be described. FIG. 2 is a cross-sectional view of flavor-generating article 110 . In the embodiment shown in FIG. 2, the flavor-generating article 110 includes a base portion 110A including a filler 111 and a first wrapping paper 112 around which the filler 111 is wound, and a side opposite to the base portion 110A. and a mouthpiece portion 110B forming an end of the . The base material portion 110A and the mouthpiece portion 110B are connected by a second wrapping paper 113 different from the first wrapping paper 112 . However, it is also possible to omit the second wrapping paper 113 and use the first wrapping paper 112 to connect the base portion 110A and the mouthpiece portion 110B.

The mouthpiece portion 110B in FIG. 2 has a paper tube portion 114 , a filter portion 115 , and a hollow segment portion 116 arranged between the paper tube portion 114 and the filter portion 115 . The hollow segment portion 116 is composed of, for example, a packing layer having one or more hollow channels and a plug wrapper covering the packing layer. Since the packed bed has a high packing density of fibers, air and aerosol flow only through the hollow channels during suction, and hardly flow inside the packed bed. In the flavor-generating article 110, shortening the length of the filter portion 115 and replacing it with the hollow segment portion 116 increases the delivery amount of the aerosol when it is desired to reduce the reduction of the aerosol component in the filter portion 115 due to filtration. effective for

Although the mouthpiece 110B in FIG. 2 is composed of three segments, in the present embodiment, the mouthpiece 110B may be composed of one or two segments, or four or more segments. It may be composed of segments. For example, the hollow segment portion 116 may be omitted, and the paper tube portion 114 and the filter portion 115 may be arranged adjacent to each other to form the mouthpiece portion 110B.

In the embodiment shown in FIG. 2, the longitudinal length of the flavor generating article 110 is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, even more preferably 50 mm to 60 mm. The circumference of the flavor generating article 110 is preferably 15 mm to 25 mm, more preferably 17 mm to 24 mm, even more preferably 20 mm to 23 mm. In the flavor generating article 110, the base portion 110A may have a length of 20 mm, the first wrapping paper 112 may have a length of 20 mm, the hollow segment portion 116 may have a length of 8 mm, and the filter portion 115 may have a length of 7 mm. However, the length of each of these segments can be changed as appropriate according to manufacturability, required quality, and the like.

In this embodiment, the fill 111 of the flavor generating article 110 may contain an aerosol source that is heated at a predetermined temperature to generate an aerosol. The type of aerosol source is not particularly limited, and extracts from various natural products and/or constituents thereof can be selected depending on the application. Aerosol sources can include, for example, glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. The content of the aerosol source in the filling 111 is not particularly limited, and is usually 5% by weight or more, preferably 10% by weight or more, from the viewpoint of sufficiently generating an aerosol and imparting a good flavor and taste. It is usually 50% by weight or less, preferably 20% by weight or less.

The filling 111 of the flavor generating article 110 in this embodiment may contain tobacco cuts as a flavor source. Materials for shredded tobacco are not particularly limited, and known materials such as lamina and backbone can be used. The content range of the filler 111 in the flavor generating article 110 is, for example, 200 mg to 400 mg, preferably 250 mg to 320 mg, when the circumference is 22 mm and the length is 20 mm. The water content of the filler 111 is, for example, 8% to 18% by weight, preferably 10% to 16% by weight. Such a water content suppresses the occurrence of winding stains, and improves the winding aptitude at the time of manufacture of the base material portion 110A. There are no particular restrictions on the size of the shredded tobacco used as the filling 111 and the preparation method thereof. For example, dried tobacco leaves cut into pieces having a width of 0.8 mm to 1.2 mm may be used. Alternatively, dried tobacco leaves may be pulverized to have an average particle size of about 20 μm to 200 μm and homogenized, processed into sheets, and cut into pieces having a width of 0.8 mm to 1.2 mm. . Furthermore, the above-described sheet-processed material may be gathered without being chopped, and used as the filling material 111 . Also, the filling 111 may contain one or more perfumes. The type of flavoring agent is not particularly limited, but menthol is preferable from the viewpoint of imparting a good smoking taste.

In this embodiment, the first wrapping paper 112 and the second wrapping paper 113 of the flavor generating article 110 can be made from base paper having a basis weight of, for example, 20 gsm to 65 gsm, preferably 25 gsm to 45 gsm. The thickness of the first wrapping paper 112 and the second wrapping paper 113 is not particularly limited, but is 10 μm to 100 μm, preferably 20 μm to 75 μm, from the viewpoint of rigidity, air permeability, and ease of adjustment during paper manufacturing. , more preferably 30 μm to 50 μm.

In this embodiment, first wrapper 112 and second wrapper 113 of flavor generating article 110 may include fillers. The content of the filler can be 10% to 60% by weight, preferably 15% to 45% by weight, based on the total weight of the first wrapping paper 112 and the second wrapping paper 113 . In this embodiment, it is preferred that the filler be 15% to 45% by weight for the preferred basis weight range (25 gsm to 45 gsm). Examples of fillers that can be used include calcium carbonate, titanium dioxide, and kaolin. Paper containing such a filler exhibits a bright white color that is preferable from the viewpoint of appearance when used as wrapping paper for the flavor-generating article 110, and can permanently maintain its whiteness. By including a large amount of such fillers, for example, the ISO whiteness of the wrapping paper can be increased to 83% or higher. Moreover, from the practical point of view of use as the 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 8 N/15 mm or more. This tensile strength can be increased by lowering the filler content. Specifically, the tensile strength can be increased by making the content of the filler less than the upper limit of the content of the filler shown in each basis weight range exemplified above.

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 taken along line 3-3 shown in FIG. 1A. As shown in FIG. 3 , the flavor inhaler 10 has a power source section 20 , a circuit section 30 and a heating section 40 in the inner spaces of the outer housing 11 and the inner housing 18 . A top housing 11A and a bottom housing 11B that constitute the outer housing 11 surround the inner housing 18 and store the inner housing 18 in the internal space.

The circuit section 30 has a first circuit board 31, a second circuit board 32, and a third circuit board 33 electrically connected to each other. The first circuit board 31 is arranged, for example, adjacent to one surface of the rectangular power supply 21 and extending in the longitudinal direction, as shown in the drawing. A partition wall 34 is provided between the first circuit board 31 and the heating section 40 to partition at least a part of the area accommodating the power supply section 20 and the first circuit board 31 . The partition wall 34 may be provided with a notch, a through hole, or the like that fluidly communicates 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 between the cover 12 and the power supply section 20 inside the top housing 11</b>A 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 . A portion of the switch 13 may come into contact with the second circuit board 32 when the user presses the switch 13 . The third circuit board 33 is arranged to extend in the longitudinal direction in a space formed on the opposite side of the opening 12a with respect to the heating unit 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 inside the bottom housing 11B such that its main surface is inclined with respect to the longitudinal direction. Thereby, 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 power supply from the power supply section 20 to the heating section 40 . Thereby, 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 section 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 . 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 section 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 source 21 can supply power to the heating section 40 so as to appropriately heat the flavor generating article 110 . Also, as shown, the power supply 21 is arranged in parallel with the heating unit 40 . Thereby, even if the size of the power source 21 is increased, it is possible to suppress the longitudinal length of the flavor inhaler 10 from increasing.

The flavor inhaler 10 also has a terminal 22 that can be connected to an external power source. The terminal 22 can be connected to a cable such as micro USB, for example. When the power source 21 is a rechargeable battery, by connecting an external power source to the terminal 22, a current can flow from the external power source to the power source 21 and the power source 21 can be charged. By connecting a data transmission cable such as a micro USB to the terminal 22, data related to the operation of the flavor inhaler 10 may be transmitted to an external device.

The heating portion 40 has a longitudinally extending heating assembly 41 , an L-shaped cross-sectional bottom cap 50 , and a substantially tubular insertion guide member 17 , as shown. The heating assembly 41 includes a plurality of tubular members and forms a tubular body as a whole. The heating assembly 41 is configured so that a portion of the flavor-generating article 110 can be accommodated therein, and has the function of defining a flow path for air supplied to the flavor-generating article 110 and the function of heating the flavor-generating article 110 from the outer periphery. have.

A first vent 15 and a second vent 19 for introducing air into the heating assembly 41 are formed in the bottom housing 11B. Specifically, the first vent 15 is in fluid communication with the upstream end of the flow path through the bottom cap 50 to the heating assembly 41 . That is, the first vent 15 is in fluid communication with the upstream end of the heating assembly 41 via the passageway through the bottom cap 50 . Also, the second vent 19 fluidly communicates with an upstream end of an air flow path 19</b>A formed between the outer housing 11 and the inner housing 18 . Further, because the downstream end of the air channel 19A is in fluid communication with the upstream end of the channel through the bottom cap 50, the second vent 19, like the first vent 15, is ultimately connected to the heating assembly 41 as well. in fluid communication.

The downstream end of heating assembly 41 is in fluid communication with the upstream end of the flow path through insertion guide member 17 to opening 12a shown in FIG. 1B. The insertion guide member 17 is a member formed of, for example, a resin material and provided between the cover 12 having the opening 12 a and the downstream end of the heating assembly 41 . When the flavor generating article 110 is inserted into the flavor inhaler 10 through the opening 12a of the cover 12 as shown in FIG. placed inside. Therefore, the insertion guide member 17 is preferably formed so that the opening on the cover 12 side is larger than the opening on the downstream side of the heating assembly 41 . This makes it easier to insert the flavor generating article 110 into the insertion guide member 17 through the opening 12a.

As shown in FIG. 1B, when the flavor-generating article 110 is inserted into the flavor inhaler 10 through the opening 12a, the user moves the portion of the flavor-generating article 110 protruding from the flavor inhaler 10, that is, the portion shown in FIG. When the air is sucked from the filter portion 115 , the air flows into the inside of the heating assembly 41 through the first vent port 15 and the second vent port 19 . The incoming air passes through the heating assembly 41 and reaches the user's mouth along 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 near the bottom cap 50) is the upstream side, and the side near the opening 12a of the heating assembly 41 (close to the insertion guide member 17) is the upstream side. 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. As shown in FIG. 4 , the heating section 40 has a heating assembly 41 , a bottom cap 50 and an insertion guide member 17 . Heating assembly 41 includes a cup-shaped container 42 forming a chamber containing flavor generating article 110 , heating member 43 , heat shrink tubing 44 and insulating member 45 .

The container 42 has at one end a first opening 42a into which the flavor generating article 110 can be inserted, and has at the other end a second opening 42b forming an air inlet, so that the flavor generating article 110 can be accommodated therein. be. In this embodiment, the container 42 has an inner wall configured to contact at least a portion of the outer wall of the flavor generating article 110 inserted through the first opening 42a. Furthermore, the container 42 has a bottom wall 42d against which the tip of the flavor-generating article 110 inserted through the first opening 42a abuts. The second opening 42 b is a through hole formed in the bottom wall 42 d 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. A boss 42c configured to press the outer wall of the inserted flavor generating article 110 radially inward is formed on the inner peripheral surface of the container 42 on the side of the first opening 42a.

The heating member 43 may be, for example, a flexible film heater configured by sandwiching a heating resistor between two films such as PI (polyimide). A heating member 43 is arranged to contact 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 cylindrical shape as a whole.

The heat-shrinkable tube 44 is cylindrical and maintains the state in which the heating member 43 is in close contact with the container 42 . Specifically, the heat-shrinkable tube 44 is heat-shrunk by applying heat in a state of being arranged on the outer peripheral side of the heating member 43 . 43 is stressed. Here, the heat-shrinkable tube 44 covers a portion of the bottom cap 50 on the downstream side and is heat-shrunk, 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 cylindrical member having a double tube structure, and is arranged radially outward from the heat shrinkable tube 44 at a predetermined interval. 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 45 a and the outer tubular member 45 b are arranged side by side in the radial direction of the inserted flavor-generating article 110 . The first annular member 45c is arranged downstream of the inner tubular member 45a and the outer tubular member 45b, and the second annular member 45d is arranged upstream of the inner tubular member 45a and the outer tubular member 45b. For example, the insulation member 45 may be a vacuum insulation material having decompressed air or vacuum inside the double tube structure. Specifically, by reducing the pressure in the space formed by the inner and outer tubular members 45a and 45b and the first and second annular members 45c and 45d, the heat generated by the heating member 43 is transferred to the heating assembly. It becomes difficult to transmit 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 that forms a pipe having a downstream end 50a that engages with the upstream end of the container 42 (the end on the second opening 42b side) and an upstream end 50b that is opposite to the downstream end 50a. . The bottom cap 50 forms an internal channel that introduces air toward the second opening 42b of the container 42 . The bottom cap 50 shown in FIG. 4 forms an L-shaped curved internal channel. In addition, 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 periphery 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 that is larger than the outer diameter of the downstream end of the container 42 so that the downstream end of the container 42 can be accommodated.

Next, the configuration of the insertion guide member 17 shown in FIG. 4 will be described. FIG. 5 is a cross-sectional view of the insertion guide member 17. As shown in FIG. 6 is a perspective view of the insertion guide member 17. FIG. 7 and 8 are cross-sectional perspective views of the insertion guide member 17. FIG. FIG. 9 is a plan view of the insertion guide member. FIG. 10 is a bottom view of the insertion guide member.

As shown in FIGS. 5 to 10, the insertion guide member 17 has an opening 61, an inner peripheral surface 62, a projecting portion 63, a guide portion 64, a groove portion 65, and an enclosing portion 66. As shown in FIGS. The opening 61 communicates with the opening 12a of the cover 12 and is configured so that the flavor generating article 110 can be inserted therein. The inner peripheral surface 62 is configured to surround the outer periphery of the flavor generating article 110 inserted from the opening 61 . In addition, 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 spaced apart from the outer peripheral surface of the inserted flavor-generating article 110. .

The protruding portion 63 is annular, protrudes from the inner peripheral surface 62 and extends over the entire circumference of the inner peripheral surface 62 . Moreover, the projecting portion 63 is configured to abut on the flavor generating article 110 over the entire outer peripheral surface of the inserted flavor generating article 110 . Here, the projecting portion 63 includes a portion where the longitudinal position of the inserted flavor generating article 110 in contact with the inserted flavor generating article 110 changes in the circumferential direction of the inner peripheral surface 62 . Specifically, the projecting portion 63 includes an inclined portion 63a, two convex portions 63b and a pair of horizontal portions 63c. The inclined portion 63a is configured to extend obliquely with respect to the longitudinal direction of the inserted flavor generating article 110 . Two convex portions 63b are provided so as to protrude toward the opening 61 side. The two convex portions 63b are arranged at equal intervals in the circumferential direction of the inner peripheral surface 62 . The horizontal portions 63c extend perpendicularly to the longitudinal direction of the inserted flavor generating article 110 and are arranged so as to face each other with respect to the central axis of the inserted flavor generating article 110. As shown in FIG. In addition, the horizontal portion 63c forms an end portion of the protruding portion 63 in the longitudinal direction of the inserted flavor generating article 110 opposite to the opening 61 (lower side in FIG. 5).

A guide portion (second guide portion) 64 is provided on the inner peripheral surface 62 and extends to the opposite side (lower side in FIG. 5) of the opening 61 along the longitudinal direction of the flavor generating article 110 inserted from the horizontal portion 63c. configured to exist. The guide portion 64 guides movement of the flavor generating article 110 with respect to the inner peripheral surface 62 . Further, the guide portion 64 has a guide surface 64a arranged to face the outer peripheral surface of the inserted flavor generating article 110 . The guide surface 64 a is configured to be spaced apart from the outer peripheral surface of the inserted flavor generating article 110 and extend along the longitudinal direction of the inserted flavor generating article 110 .
