Technical problem to be solved by the invention

In the flavor inhaler described in patent document 1, the tubular portion and the base portion are integrally formed of the same member, and the housing portion is formed. Therefore, there is a problem in that fine processing of the base portion is difficult.

The present invention has been made to solve at least some of the above problems, and an object of the present invention is to provide a fragrance absorber which is highly processable, inexpensive, and has a housing portion having a desired fine shape.

Technical scheme for solving technical problems

According to a first aspect of the present invention, a fragrance absorber is provided. The fragrance absorber comprises a housing part, wherein an opening is formed at one end of the housing part, at least one part of the fragrance generating article is housed through the opening, and the housing part comprises: a cylindrical portion surrounding the periphery of the flavor generating article; and an abutting portion which is disposed in the cylindrical portion and is formed of a member different from the cylindrical portion at the other end of the housing portion, and which abuts against the flavor generating article housed in the housing portion.

According to the first aspect of the present invention, the housing portion is constituted by the cylindrical portion and the abutting portion formed by a member different from the cylindrical portion, and therefore the housing portion can be formed by combining the abutting portion subjected to fine processing in advance with the cylindrical portion. Therefore, the flavor aspirator having a housing portion with a desired fine shape can be obtained at a high workability and a low cost.

In a second aspect of the present invention, in addition to the first aspect, the contact portion is made of a resin.

According to the second aspect of the present invention, since the contact portion is made of resin, high workability can be achieved.

In a third aspect of the present invention, in addition to the second aspect, a first air flow path communicating with the flavor generating article stored in the storage portion is formed in the contact portion.

According to the third aspect of the present invention, the abutting portion is made of resin, so that the air flow path can be precisely designed.

In a fourth aspect of the present invention, in the third aspect, the tubular portion includes: a contact portion that contacts the flavor-generating article when the flavor-generating article is accommodated in the accommodating portion; a separation portion that is adjacent to the contact portion in a circumferential direction and is separated from the flavor-generating article; when the flavor generating article is accommodated in the accommodating portion, a second air flow path communicating with the first air flow path is formed between the separating portion and the flavor generating article.

According to the fourth aspect of the present invention, the air introduced into the housing portion is supplied to the flavor generating article through the second air flow path and the first air flow path, and can reach the inside of the mouth of the user, so that it is not necessary to provide an additional flow path for introducing the air supplied to the flavor generating article to the flavor inhaler. Therefore, the structure of the fragrance absorber can be simplified, and the fragrance absorber can be miniaturized.

In a fifth aspect of the present invention, in any one of the first to fourth aspects, the cylindrical portion is made of metal.

According to the fifth aspect of the present invention, the tubular portion is made of metal, so that heat can be efficiently transferred from the tubular portion to the flavor-generating article.

In a sixth aspect of the present invention, in any one of the first to fifth aspects, the cylindrical portion has a non-cylindrical shape.

According to the sixth aspect of the present invention, since the housing portion is constituted by the cylindrical portion and the contact portion formed by a member different from the cylindrical portion, even if the cylindrical portion is shaped like an ellipse or a square tube, the contact portion can be subjected to fine processing regardless of the shape of the cylindrical portion, and the workability of the housing portion can be improved.

In a seventh aspect of the present invention, in addition to any one of the first to sixth aspects, a closing portion that closes between the cylindrical portion and the abutting portion is further provided.

In an eighth aspect of the present invention, in addition to any one of the first to seventh aspects, a heating portion configured to heat the flavor-generating article stored in the storage portion is further provided, the contact portion and the heating portion being not overlapped in an axial direction of the storage portion.

According to the eighth aspect of the present invention, since the abutting portion and the heating portion do not overlap in the axial direction of the housing portion, heat from the heating portion is less likely to be transferred to the abutting portion, and deterioration of the abutting portion due to heat can be suppressed.

In a ninth aspect of the present invention, in any one of the first to eighth aspects, the abutment portion is engaged with a bottom portion formed on the other end side of the housing portion in the cylindrical portion.

According to the ninth aspect of the present invention, the abutting portion is engaged with the bottom of the cylindrical portion, so that the abutting portion can be positioned and supported in the cylindrical portion.

In a tenth aspect of the present invention, in addition to any one of the first to ninth aspects, a support portion engaged with the contact portion via the tubular portion is further provided.

According to the tenth aspect of the present invention, the support portion and the abutment portion are engaged, and therefore the cylindrical portion can be supported by the abutment portion and the support portion.

In an eleventh aspect of the present invention, in addition to the tenth aspect, a rotation preventing mechanism is further provided that prevents relative rotation of the support portion with respect to the cylindrical portion about an axial direction of the housing portion as a rotation axis.

According to the eleventh aspect of the present invention, since the rotation preventing mechanism is provided, relative rotation with respect to the support portion of the cylindrical portion can be prevented.

In a twelfth aspect of the present invention, in the tenth or eleventh aspect, the abutting portion is formed with an air layer on the opposite side of the abutting surface abutting against the flavor-generating article accommodated in the accommodating portion in a state of being engaged with the supporting portion.

According to the twelfth aspect of the present invention, since the air layer is formed on the opposite side of the abutting surface of the abutting portion against the flavor generating article, heat loss due to heat transfer from the abutting portion can be suppressed.

In a thirteenth aspect of the present invention, in any one of the tenth to twelfth aspects, a bottom portion formed on the other end side of the housing portion in the tubular portion is sandwiched and supported by the abutting portion and the supporting portion.

According to the thirteenth aspect of the present invention, the bottom of the tubular portion is supported by sandwiching the contact portion and the support portion, so that the tubular portion can be firmly fixed, and the firmness can be improved.

In a fourteenth aspect of the present invention, in addition to any one of the first to thirteenth aspects, a guide portion that abuts against an opening of the tubular portion and guides insertion of the flavor generating article into the tubular portion is further provided.

According to the fourteenth aspect of the present invention, since the guide portion is provided at the opening of the tubular portion, the flavor generating article can be easily inserted into the tubular portion.

In a fifteenth aspect of the present invention, in addition to the fourteenth aspect, a cover portion is further provided, the cover portion being disposed so as to cover a periphery of the contact portion between the cylindrical portion and the guide portion.

Detailed Description

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 overlapping description thereof is omitted.

Fig. 1A is a schematic front view of the fragrance extracting device 100 according to the present embodiment. Fig. 1B is a schematic plan view of the fragrance extraction device 100 according to the present embodiment. Fig. 1C is a schematic bottom view of the fragrance extraction device 100 according to the present embodiment. In the drawings described in the present specification, an X-Y-Z rectangular coordinate system is added for convenience of description. In this coordinate system, the Z axis is oriented vertically upward, the X-Y plane is configured to cut off the fragrance absorber 100 in the horizontal direction, and the Y axis is configured to extend from the front side to the back side of the fragrance absorber 100. The Z axis is the direction of insertion of the flavor generating article in the chamber 50 housed in the atomizing area 30 described later, and may be the axial direction of the chamber 50. The X axis is a direction orthogonal to the Y axis and the Z axis, and the X axis and the Y axis are a radial direction orthogonal to the axial direction, or may be a radial direction of the chamber 50.

The flavor inhaler 100 according to the present embodiment is configured to generate a flavor-containing aerosol by heating a stick-type flavor generating article having a flavor source including an aerosol source, for example.

As shown in fig. 1A to 1C, the fragrance absorber 100 includes a housing 101 (corresponding to an example of a case), a slide cover 102, and a switch 103. The housing 101 constitutes the outermost shell of the fragrance absorber 100, having a size to be incorporated into the hand of a user. When the user uses the fragrance absorber 100, the fragrance absorber 100 is held by hand and aerosol can be absorbed. The housing 101 may be formed by combining a plurality of members. The housing 101 is made of, for example, a resin, particularly, a Polycarbonate (PC), an ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), a polymer alloy containing a plurality of polymers, or the like, or may be formed of a metal such as aluminum.

The housing 101 has an opening, not shown, for receiving the fragrance-generating article, and the slide cover 102 is slidably attached to the housing 101 so as to close the opening. Specifically, the slide cover 102 is configured to be movable along the outer surface of the housing 101 between a closed position (a position shown in fig. 1A and 1B) in which the opening of the housing 101 is closed, and an open position in which the opening is opened. For example, the sliding cover 102 can be moved to the closed position or the open position by a user manually operating the sliding cover 102. Thus, the sliding cover 102 can allow or restrict the scent generating articles from entering the interior of the scent extractor 100.

The switch 103 is used to switch the operation of the fragrance absorber 100 on and off. For example, by operating the switch 103 in a state where the user inserts the flavor generating article into the flavor inhaler 100, power is supplied from a power source, not shown, to a heater, not shown, so that the flavor generating article can be heated without burning. The switch 103 may be a switch provided outside the housing 101 or may be a switch provided inside the housing 101. When the switch is located inside the casing 101, the switch is indirectly pressed by pressing the switch portion 103 on the surface of the casing 101. In this embodiment, an example will be described in which the switch of the switch unit 103 is located inside the housing 101.

The fragrance absorber 100 may further have terminals not shown. The terminal may be an interface connecting the fragrance absorber 100 with, for example, an external power source. When the power source provided in the fragrance extraction device 100 is a rechargeable battery, the external power source is connected to the terminal, and the external power source causes a current to flow into the power source, thereby charging the power source. Further, the data related to the operation of the fragrance absorber 100 may be transmitted to an external device by connecting a data transmission line to the terminal.

Next, a scent generating article used in the scent pick-up 100 according to the present embodiment will be described. Fig. 2 is a schematic side sectional view of the flavor generating article 110. In the present embodiment, the smoking system may be constituted by the flavor inhaler 100 and the flavor generating article 110. In the example shown in fig. 2, the flavor generating article 110 has a smokable article 111, a tubular member 114, a hollow filter 116, and a filter 115.

The smokable article 111 is wrapped by a first wrapper 112. The tubular member 114, the hollow filtration section 116, and the filtration section 115 are wound with a second roll paper 113 different from the first roll paper 112. The second roll paper 113 also wraps a portion of the first roll paper 112 around which the smokable article 111 is wrapped. Thereby, the tubular member 114, the hollow filter 116, and the filter 115 are connected to the smokable object 111. The second roll paper 113 may be omitted, and the tubular member 114, the hollow filter 116, the filter 115, and the smokable article 111 may be connected to each other by the first roll paper 112. An anti-lip blocking agent 117 for making the lips of the user easily separate from the second roll paper 113 is coated on the outer surface near the end portion of the second roll paper 113 on the filter portion 115 side. The portion of the fragrance generating article 110 coated with the anti-lip adhesion 117 functions as a suction nozzle of the fragrance generating article 110.

The smokable article 111 may comprise a flavour source, such as a cigarette, and an aerosol source. The first roll paper 112 around which the smokable article 111 is wound may be a sheet member having air permeability. The tubular member 114 may be a paper tube or a hollow filter. In the illustrated example, the flavor generating article 110 includes the smokable article 111, the tubular member 114, the hollow filter 116, and the filter 115, but the configuration of the flavor generating article 110 is not limited thereto. For example, the hollow filter 116 may be omitted, and the tubular member 114 and the filter 115 may be disposed adjacent to each other.

Next, the internal structure of the fragrance extracting device 100 will be described. Fig. 3 is a cross-sectional view of the fragrance extraction 100 shown in fig. 1B, looking at 3-3. As shown in fig. 3, an inner case 10 (corresponding to one example of a case) is provided on the inner side of an outer case 101 of the fragrance absorber 100. The inner case 10 is made of, for example, a resin, in particular, a Polycarbonate (PC), an ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), a polymer alloy containing a plurality of polymers, or the like, or may be formed of a metal such as aluminum. Further, from the viewpoints of heat resistance and strength, the inner case 10 is preferably PEEK. The power supply unit 20 and the atomizing unit 30 are provided in the inner space of the inner case 10.

The power supply unit 20 has a power supply 21. 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 atomizing area 30. Thus, the power supply 21 can supply power to the atomizing area 30 in order to appropriately heat the flavor generating article 110.

As shown in the drawing, the atomizing area 30 includes a metallic chamber 50 (corresponding to an example of a cylindrical portion) extending in the direction of insertion (Z-axis) of the flavor generating article 110, a heater 40 covering a part of the chamber 50, a heat insulating portion 32, and a substantially cylindrical insertion guide member 34 (corresponding to an example of a guide portion) that abuts against an opening 52 (see fig. 4A) of the chamber 50. The chamber 50 is configured to surround the scent generating article 110. The heater 40 is configured to include a heating portion 42 (see fig. 6) that contacts the outer peripheral surface of the chamber 50 and heats the flavor generating article 110 inserted into the chamber 50.

As shown in the drawing, a bottom member 36 (corresponding to an example of the contact portion) is provided at the bottom of the chamber 50. The base member 36 abuts against the flavor generating article 110 inserted into the chamber 50 in the insertion direction of the flavor generating article 110, and functions as a stopper for positioning the flavor generating article 110. Here, the chamber 50 and the base 36 constitute a housing portion that houses at least a part of the flavor generating article 110. The bottom member 36 can be formed of a resin material, for example. The base member 36 has irregularities on the surface where the flavor-generating article 110 is in contact with, and can define a first air flow path that is in contact with the flavor-generating article 110 and that can supply air to the air intake port of the flavor-generating article 110, that is, that communicates with the flavor-generating article 110 accommodated in the accommodating portion. The base member 36 is made of, for example, a resin, and may be formed of, in particular, a Polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene copolymer), a resin PEEK (polyetheretherketone), a polymer alloy containing a plurality of polymers, or the like, or a metal such as aluminum. In addition, the bottom member 36 is preferably formed of a material having a low thermal conductivity in order to suppress heat transfer to the heat insulating portion 32 and the like.

The chamber 50 and the base member 36 formed of a member different from the chamber 50 constitute a housing portion, and the housing portion can be formed by combining the base member 36 subjected to fine processing in advance with the chamber 50. Therefore, the flavor inhaler 100 having a housing portion with a desired fine shape can be obtained at a high workability and a low cost. In addition, since the base member 36 is made of resin, high workability can be achieved, and therefore the first air flow path can be precisely designed.

The heat insulating portion 32 is generally cylindrical in shape as a whole, and is disposed so as to cover the chamber 50. The insulation 32 may comprise, for example, an aerogel sheet. The insertion guide member 34 is provided between the slide cover 102 and the chamber 50 in the closed position. The insertion guide member 34 is made of, for example, a resin, and in particular, can be formed of a Polycarbonate (PC), an ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), a polymer alloy containing a plurality of polymers, or the like. The insertion guide member 34 may be made of metal, glass, ceramic, or the like. In addition, from the viewpoint of heat resistance, the insertion guide member 34 is preferably PEEK. The insertion guide member 34 communicates with the outside of the fragrance absorber 100 when the slide cover 102 is in the open position, and the insertion of the fragrance generating article 110 into the chamber 50 is guided by inserting the fragrance generating article 110 into the guide member 34. By providing the insertion guide member 34, the flavor generating article 110 can be easily inserted into the chamber 50.

The fragrance absorber 100 further includes a first holding portion 37 and a second holding portion 38 that hold both ends of the chamber 50 and the heat insulating portion 32. The first holding portion 37 is disposed to hold the chamber 50 and the end portion of the heat insulating portion 32 on the negative Z-axis side. The second holding portion 38 is disposed so as to hold the chamber 50 and an end portion of the heat insulating portion 32 on the sliding cover 102 side (Z-axis positive direction side). The first holding portion 37 and the second holding portion 38 will be described in detail later.

Next, the structure of the chamber 50 will be described. Fig. 4A is a perspective view of chamber 50. Fig. 4B is a cross-sectional view of chamber 50 shown in fig. 4A looking at 4B-4B. Fig. 5A is a cross-sectional view of chamber 50 shown in fig. 4B looking at 5A-5A. Fig. 5B is a cross-sectional view of chamber 50 shown in fig. 4B looking at 5B-5B. Fig. 6 is a perspective view of the chamber 50 and the heater 40.

As shown in fig. 4A and 4B, the chamber 50 may be a cylindrical member including an opening 52 into which the flavor generating article 110 is inserted, and a cylindrical side wall portion 60 that accommodates the flavor generating article 110. A flange portion 52a is formed at an end of the opening 52 defining the chamber 50. The chamber 50 is preferably formed of a material having heat resistance and a small thermal expansion coefficient, and may be formed of stainless steel or the like, for example. The chamber 50 may be formed of a resin such as PEEK, glass, or ceramic, in addition to metal. This allows the fragrance generating article 110 to be efficiently heated from the chamber 50.

As shown in fig. 4B and 5B, the side wall portion 60 includes a contact portion 62 and a separation portion 66. When the flavor generating article 110 is disposed at a desired position in the chamber 50, the contact portion 62 contacts or presses a part of the flavor generating article 110 on a surface intersecting the insertion direction of the flavor generating article 110, and the separation portion 66 is separated from the flavor generating article 110. In the present specification, the "desired position in the chamber 50" may be a position where the flavor generating article 110 is appropriately heated, or may be a position of the flavor generating article 110 when the user smokes.

The side wall portion 60 includes the contact portion 62 and the separation portion 66, so the cross-sectional shape orthogonal to the axial direction of the chamber 50 of the side wall portion 60 is an elliptical shape, that is, has a non-cylindrical shape. In this case, since the housing portion is constituted by the chamber 50 and the base member 36 formed of a member different from the chamber 50, even if the chamber 50 is shaped like an ellipse or a square tube, for example, the chamber 50 can be finely processed on the base member 36 regardless of the shape of the chamber 50, and the workability of the housing portion can be improved.

The contact portion 62 has an inner surface 62a and an outer surface 62b. The separator 66 has an inner surface 66a and an outer surface 66b. As shown in fig. 6, the heater 40 is disposed on the outer surface 62b of the contact portion 62. Thereby, the heat generated by the heating portion 42 of the heater 40 is transferred to the flavor generating article 110 in contact with the contact portion 62. The heater 40 is preferably disposed on the outer surface 62b of the contact portion 62 without a gap. The heater 40 may include an adhesive layer. In this case, the heater 40 including the adhesive layer is preferably disposed on the outer surface 62b of the contact portion 62 without a gap.

As shown in fig. 4A and 5B, the outer surface 62B of the contact portion 62 is a plane. Since the outer surface 62b of the contact portion 62 is flat, when the band-shaped electrode 48 is connected to the heater 40 disposed on the outer surface 62b of the contact portion 62 as shown in fig. 6, the band-shaped electrode 48 can be prevented from being bent. As shown in fig. 4B and 5B, the inner surface 62a of the contact portion 62 is a plane. As shown in fig. 4B and 5B, the contact portion 62 has a uniform thickness.

As shown in fig. 4A, 4B, and 5B, the chamber 50 has two contact portions 62 in the circumferential direction of the chamber 50, and the two contact portions 62 are opposed to each other in parallel. At least a portion of the distance between the inner surfaces 62a of the two contact portions 62 is preferably smaller than the width of the portion of the flavor generating article 110 inserted into the chamber 50 that is disposed between the contact portions 62.

As shown in fig. 5B, the inner surface 66a of the separation portion 66 may have an overall circular arc-shaped cross section on a surface orthogonal to the longer direction (Z-axis direction) of the chamber 50. In addition, the separation portion 66 is arranged adjacent to the contact portion 62 in the circumferential direction.

As shown in fig. 4B, the chamber 50 may have a hole 56a in its bottom 56 so that the base member 36 shown in fig. 3 penetrates and is disposed inside the chamber 50. The bottom member 36 can be fixed to the inside of the bottom 56 of the chamber 50 by an adhesive or the like. The adhesive functions as a seal between the enclosed chamber 50 and the base member 36. The adhesive interposed between the base member 36 and the bottom portion 56 may be made of a resin material such as epoxy resin. Alternatively, an inorganic adhesive such as cementing or welding may be used. Thus, the chamber 50 and the bottom member 36 are firmly fixed to each other, and the firmness can be improved.

The base member 36 provided at the base 56 supports a portion of the flavor-generating article 110 inserted into the chamber 50 so as to expose at least a portion of the end surface of the flavor-generating article 110. The bottom 56 supports a part of the flavor generating article 110 so that the end surface of the flavor generating article 110 exposed communicates with a space 67 (see fig. 7) described later.

As shown in fig. 4A and 4B, the chamber 50 preferably has a cylindrical non-holding portion 54 between the opening 52 and the side wall portion 60. In a state where the fragrance generating article 110 is positioned at a desired position of the chamber 50, a gap can be formed between the non-holding portion 54 and the fragrance generating article 110. As shown in fig. 4A and 4B, the chamber 50 preferably has a first guide portion 58 having a tapered surface 58a connecting the inner surface of the non-holding portion 54 and the inner surface 62a of the contact portion 62.

As shown in fig. 6, the heater 40 has a heating portion 42. The heating portion 42 may be, for example, a heating rail. The heating portion 42 is preferably configured to heat the contact portion 62 without contacting the separation portion 66 of the chamber 50. In other words, the heating portion 42 is preferably disposed only on the outer surface of the contact portion 62. The heating portion 42 may also have a difference in heating capacity between the portion of the separation portion 66 of the heating chamber 50 and the portion of the heating contact portion 62. Specifically, the heating portion 42 may be configured to heat the contact portion 62 at a higher temperature than the separation portion 66. For example, the arrangement density of the heating tracks of the heating portion 42 at the contact portion 62 and the separation portion 66 may be adjusted. The heating portion 42 may have substantially the same heating capacity throughout the entire periphery of the chamber 50, and may be wound around the outer periphery of the chamber 50.

As shown in fig. 6, the heater 40 preferably has an electric insulating member 44 covering at least one surface of the heating portion 42 in addition to the heating portion 42. In the present embodiment, the electric insulating member 44 is disposed so as to cover both surfaces of the heating portion 42. Here, the bottom member 36 may be configured not to coincide with the heating portion 42 in the axial direction of the chamber 50. Thereby, heat from the heating portion 42 is hard to transfer to the base member 36, so that deterioration of the base member 36 due to heat can be suppressed.

Fig. 7 is a cross-sectional view of fig. 5B showing a state in which the flavor generating article 110 is disposed at a desired position in the chamber 50. As shown in fig. 7, when the flavor generating article 110 is disposed at a desired position in the chamber 50, the flavor generating article 110 can be pressed in contact with the contact portion 62 of the chamber 50. On the other hand, a space 67 is formed between the flavor generating article 110 and the separating portion 66. The void 67 can communicate with the opening 52 of the chamber 50, the end face of the scent generating article 110 positioned within the chamber 50. Thus, the air flowing in from the opening 52 of the chamber 50 can flow into the interior of the flavor generating article 110 through the void 67. In other words, a second air flow path (void 67) is formed between the flavor generating article 110 and the separating section 66.

Next, an air flow path of the fragrance extraction device 100 according to the present embodiment will be described. Fig. 8 is a perspective view showing an air flow path of the fragrance extracting device according to the present embodiment. In fig. 8, the flavor generating article 110 is not shown. As shown in fig. 8, the second air flow path 150 formed between the scent generating article 110 and the separating portion 66 communicates with the first air flow path 160 formed in the base member 36, and the first air flow path 160 communicates with the third air flow path 170 passing through the inside of the scent generating article 110.

In this way, the air introduced into the housing portion is supplied to the flavor generating article 110 through the second air flow path 150 and the first air flow path 160, and can reach the user's mouth, so that it is unnecessary to provide an additional flow path for introducing the air supplied to the flavor generating article 110 to the flavor inhaler 100. Therefore, the structure of the fragrance absorber 100 can be simplified, and the fragrance absorber 100 can be miniaturized.

Next, the structure of the first holding portion 37 and the second holding portion 38 that hold the chamber 50 and the heat insulating portion 32 will be described. Fig. 9 is an enlarged cross-sectional view of the first holding portion 37. Fig. 10 is an enlarged cross-sectional view of the second holding portion 38.

First, if the heat insulating portion 32 covering the chamber 50 is completely fixed to the inner case 10 or the outer case 101, when an impact from the outside is applied to the fragrance absorber 100, the impact may not be buffered, and the heat insulating portion 32 may be broken. In addition, in the case where the heat insulating portion 32 expands due to the heat of the chamber 50 (or the heater 40), the fixed heat insulating portion 32 may be bent due to the thermal expansion.

Therefore, the first holding portion 37 and the second holding portion 38 of the present embodiment hold the heat insulating portion 32 so as to be movable in the axial direction of the chamber 50 or in the radial direction (for example, the X-axis direction or the Y-axis direction) of the chamber 50 orthogonal to the axial direction. The first holding portion 37 and the second holding portion 38 may hold the heat insulating portion so as to be movable only in the axial direction of the chamber 50, or may hold the heat insulating portion so as to be movable only in the radial direction orthogonal to the axial direction.

As shown in fig. 9, the bottom member 36 engages the bottom 56 of the chamber 50. Thereby, the bottom member 36 can be positioned and supported in the chamber 50. In addition, the bottom member 36 provided inside the bottom 56 of the chamber 50 has a shaft portion 36a passing through the hole 56a of the chamber 50 and protruding to the outside of the chamber 50. The shaft 36a has a flat surface 36b (corresponding to an example of the rotation preventing mechanism) at an end portion. The first holding portion 37 includes a support portion 72, a heating pad 74 (first restriction portion corresponds to an example of one end side restriction portion), and a ring 85 (second restriction portion corresponds to an example).

The support portion 72 is configured to receive the shaft portion 36a of the base member 36 and support the chamber 50. Specifically, the bottom 56 of the chamber 50 is supported by being sandwiched by the bottom member 36 and the support portion 72. The support portion 72 is made of, for example, a resin, and in particular, can be formed of a Polycarbonate (PC), an ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), a polymer alloy containing a plurality of polymers, or the like. The support portion 72 may be made of metal, glass, ceramic, or the like. In addition, from the viewpoint of heat resistance, the support portion 72 is preferably PEEK. Thus, the chamber 50 is specifically supported by sandwiching the bottom 56 of the chamber 50 between the bottom member 36 and the support portion 72 engaged with the bottom member 36. Thus, the chamber 50 is firmly fixed, and the firmness can be improved.

The support portion 72 has a flat surface 72a (corresponding to an example of the rotation preventing mechanism) so as to face the flat surface 36b of the shaft portion 36a. By engaging the flat surface 36b of the shaft 36a with the flat surface 72a of the support 72, the support 72 can be prevented from rotating relative to the chamber 50.

In addition, the bottom member 36, in a state of being engaged with the support portion 72, forms an air layer 36d on the opposite side of the contact surface 36c with the flavor generating article 110 housed in the housing portion. That is, the base member 36 is not in direct contact with the heating pad 74. Therefore, heat loss due to heat transfer from the bottom member 36 can be suppressed.

The heating pad 74 is configured to receive and support one end of the support portion 72. The heating pad 74 can be formed of an elastic member such as silicone rubber. In the case of using silicone rubber, the hardness is suitably in the range of 40 to 60 Shore, and may be suitably selected according to the deformation of the heating pad 74. The heating pad 74 is configured to be fixed to the fixing portion 22 fixed to the inner case, not shown. The fixing portion 22 may be the inner case itself.

Here, the heating pad 74 is formed of an elastic member such as silicone rubber, for example, as described above, and biases the chamber 50 toward the insertion guide member 34, that is, the axial direction side, via the support portion 72. Accordingly, a seal is formed between the flange portion 52a of the chamber 50 and the insertion guide member 34, so that the aerosol generated in the chamber 50 by the heating of the flavor generating article 110 can be prevented from leaking out into the inner casing from between the chamber 50 and the insertion guide member 34.

The heating pad 74 is disposed so as to face the heat insulating portion 32 with a gap therebetween, and restricts movement of the heat insulating portion 32 in the axial direction of the chamber 50. Accordingly, the heat insulating portion 32 is prevented from moving unrestrained in the axial direction of the chamber 50, and thus the heat insulating portion 32 is prevented from colliding with other components (e.g., the inner case 10, etc.). Further, since the heating pad 74 is formed of an elastic member, even when the heating pad 74 is in contact with the heat insulating portion 32, the stress applied to the heat insulating portion 32 can be relaxed, and therefore, the heat insulating portion 32 can be prevented from being broken.

The ring 85 has an opening 85a into which the support portion 72 is inserted, and can be fixed by being sandwiched between the support portion 72 and the heating pad 74. The ring 85 is made of, for example, a resin, and in particular, can be formed of a Polycarbonate (PC), an ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), a polymer alloy containing a plurality of polymers, or the like. The ring 85 may be made of metal, glass, ceramic, or the like. In addition, from the viewpoint of heat resistance, the ring 85 is preferably PEEK. The ring 85 is disposed so as to face a support 32a, which will be described later, provided on the inner peripheral surface of the heat insulating portion 32 with a gap therebetween, and restricts movement of the heat insulating portion 32 in the radial direction of the chamber 50. Accordingly, the heat insulating portion 32 is prevented from moving limitlessly in the radial direction of the chamber 50, and thus the heat insulating portion 32 is prevented from colliding with other members (e.g., the inner case 10, etc.). Further, the movement of the heat insulating portion 32 in the radial direction of the chamber 50 can be restricted from the inside of the heat insulating portion 32, and the fragrance absorber 100 can be miniaturized.

The heat insulating portion 32 includes a support 32a and a heat insulating layer 32b provided on the outer peripheral surface of the support 32 a. The support 32a is, for example, substantially cylindrical, and is disposed so as to surround the chamber 50. The support 32a is made of, for example, a resin, and in particular, can be formed of a Polycarbonate (PC), an ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), a polymer alloy containing a plurality of polymers, or the like. The insulating layer 32b can be, for example, a aerogel sheet. Here, the support 32a is formed thinner than the heat insulating layer 32b, and has a thickness of 1mm or less, preferably 0.5mm or less. This reduces the heat capacity of the heat insulating portion 32 itself, and thus suppresses heat loss in the heat insulating portion 32.

As shown in fig. 10, the flange 52a of the chamber 50 is configured to contact the insertion guide member 34 over the entire circumference. The second holding portion 38 includes a pad 80 (corresponding to an example of the cover portion) and an annular member 90 (corresponding to an example of the cover portion).

The gasket 80 is disposed around the non-holding portion 54 of the chamber 50 and supports the chamber 50. The gasket 80 is made of, for example, a resin, and in particular, can be formed of a Polycarbonate (PC), an ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), a polymer alloy containing a plurality of polymers, or the like. The pad 80 may be made of metal, glass, ceramic, or the like. Further, from the viewpoint of heat resistance, the gasket 80 is preferably PEEK. The annular member 90 is configured to engage with and support the insertion guide member 34 and the pad 80. The annular member 90 can be formed of an elastic member such as silicone rubber. In the case of using silicone rubber, the hardness is suitably in the range of 40 to 60 Shore, and may be suitably selected in accordance with the deformation of the annular member 90. The ring member 90 is configured to be fixed to the fixing portion 22 fixed to the inner case, not shown.

The gasket 80 and the annular member 90 are disposed so as to cover the periphery of the abutment portion between the chamber 50 and the insertion guide member 34. This can prevent the aerosol generated in the chamber 50 from leaking out of the contact portion between the chamber 50 and the insertion guide member 34 into the inner casing of the flavor inhaler 100.

The packing 80 and the annular member 90 are disposed so as to face the heat insulating portion 32 with a gap therebetween, and restrict movement of the heat insulating portion 32 in the axial direction of the chamber 50. Accordingly, the heat insulating portion 32 is prevented from moving unrestrained in the axial direction of the chamber 50, and thus the heat insulating portion 32 is prevented from colliding with other components (e.g., the inner case 10, etc.). Further, since the annular member 90 is formed of an elastic member, even when the annular member 90 contacts the heat insulating portion 32, the stress received by the heat insulating portion 32 can be relieved, and therefore, the heat insulating portion 32 can be prevented from being broken.

The packing 80 is disposed so as to face the inner portion Zhou Miandai of the heat insulating portion 32 with a gap therebetween, and restricts movement of the heat insulating portion 32 in the radial direction of the chamber 50. Accordingly, the heat insulating portion 32 is prevented from moving limitlessly in the radial direction of the chamber 50, and thus the heat insulating portion 32 is prevented from colliding with other members (e.g., the inner case 10, etc.). Further, the movement of the heat insulating portion 32 in the radial direction of the chamber 50 can be restricted from the inside of the heat insulating portion 32, and the fragrance absorber 100 can be miniaturized.

Here, regarding the distance between the heating pad 74 and the packing 80 and the annular member 90, specifically, the distance between the heating pad 74 and the packing 80 and the annular member 90 at the position facing the heat insulating portion 32 is L1, and the axial length of the heat insulating portion 32 is L2, a relationship of L1 > L2 is preferably established. Thereby, the heat insulating portion 32 can be disposed at a non-contact position with respect to the heating pad 74, the pad 80, and the annular member 90. Therefore, the heat insulating portion 32 can be suppressed from receiving stress from the heating pad 74, the packing 80, and the annular member 90.

In the present embodiment, the heating pad 74 is positioned and fixed to the fixing portion 22, but the present invention is not limited to this. Fig. 11 is an enlarged cross-sectional view showing another mode of the first holding portion. As shown in fig. 12, the first holding portion 137 includes a ring 172 (corresponding to an example of a supporting portion) and a heating pad 174. In addition, the bottom member 36 provided at the bottom 56 of the chamber 50 has a shaft portion 36a protruding to the outside of the chamber 50 through the hole 56a of the chamber 50.

The ring 172 is configured to abut the bottom 56 of the chamber 50 and support the chamber 50. Further, the ring 172 has a hole 172a in a central portion through which the shaft 36a of the base member 36 passes. The ring 172 is made of, for example, a resin, and in particular, can be formed of a Polycarbonate (PC), an ABS (acrylonitrile-butadiene-styrene copolymer) resin, PEEK (polyether ether ketone), a polymer alloy containing a plurality of polymers, or the like.

The heating pad 174 is configured to receive and support one end of the ring 172. The heating pad 174 has a hole 174a in a central portion through which the shaft 36a of the base member 36 passes. The heating pad 174 may be formed of an elastic member such as silicon.

The bottom member 36 is configured such that a shaft portion 36a is positioned and fixed to a fixing portion 22 fixed to an inner case, not shown. The fixing portion 22 may be the inner case itself.

In the first holding portion 137 having such a structure, the heating pad 174 biases the chamber 50 toward the insertion guide member 34, and a seal is formed between the flange portion 52a of the chamber 50 and the insertion guide member 34, so that it is possible to suppress leakage of the aerosol generated in the chamber 50 by heating the flavor generating article 110 from between the chamber 50 and the insertion guide member 34 into the inner case.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications are possible within the scope of the technical idea described in the claims, the specification, and the drawings. Any shape or material not directly described in the specification and drawings is included in the technical idea of the present invention as long as the effects of the present invention are obtained.

For example, the flavor inhaler 100 of the present embodiment has a so-called crossflow air flow path for supplying air flowing in from the opening 52 of the chamber 50 to the end surface of the flavor generating article 110, but the present invention is not limited to this, and may have a so-called underflow air flow path for supplying air from the bottom 56 of the chamber 50 into the chamber 50. The heating unit 42 is not limited to the resistance heating type, and may be an induction heating type. In this case, the heating portion 42 may heat the chamber 50 by induction heating. In addition, in the case where the flavor generating article 110 has a susceptor, the heating section 42 can heat the susceptor of the flavor generating article 110 by induction heating.
