Description

The present invention relates to flavor inhalers.

2. Description of the Related Art Conventionally, flavor inhalers for inhaling flavor or the like without burning materials are known. The flavor inhaler has, for example, a chamber containing the flavor-generating article, a heater for heating the flavor-generating article contained in the chamber, and a heat insulating material for suppressing heat transfer from the heater to the housing (see, for example, Patent Reference 1). In Patent Document 1, the top and the base hold the heat insulating material and the sleeve so as to sandwich them in the axial direction.

WO2020/035454

A member placed near the heater may expand due to the heat of the heater. Therefore, when such a member is completely fixed, there is a possibility that the fixed member may buckle if thermal expansion occurs in the fixed member. Moreover, if a member made of a fragile material such as an airgel sheet is completely fixed to the housing, the member cannot absorb the impact when the flavor inhaler is subjected to an external impact. There is also a risk that the impact will be transmitted to itself and this member will be destroyed.

One of the objects of the present invention is to suppress breakage of members constituting a flavor inhaler.

According to a first aspect, a flavor inhaler is provided. This flavor inhaler comprises a housing, a storage portion that is housed in the housing and stores consumables, a tubular portion that surrounds the storage portion, and an axial direction of the tubular portion or a second direction perpendicular to the axial direction. a holding part that holds the tubular part movably in one direction.

According to the first aspect, the tubular portion is held by the holding portion so as to be movable in the axial direction or the first direction. That is, since the cylindrical portion is not completely fixed and there is a space in which the cylindrical portion moves, the cylindrical portion can thermally expand in this space, and the buckling of the cylindrical portion can be suppressed. can. In addition, even if an external impact is applied to the flavor inhaler, the movement of the tubular portion can absorb the impact, thereby suppressing breakage of the tubular portion. In addition, in this specification, the tubular portion may be a tubular body having any shape such as a cylindrical shape or a square tubular shape. In addition, the term "holding" as used herein means restricting the movement of an object so as to position the object within a predetermined area, and is limited to physically gripping or holding the object. can't

A second aspect is characterized in that, in the first aspect, the holding portion includes a first restricting portion that restricts movement of the cylindrical portion in the first direction.

According to the second aspect, the first restricting portion can restrict movement of the tubular portion in the first direction while the tubular portion is movable in the first direction. Therefore, the tubular portion is prevented from endlessly moving in the first direction, and collision between the tubular portion and other members (for example, the housing or the accommodating portion) can be prevented.

A third aspect is characterized in that, in the second aspect, the first restricting portion is configured to restrict movement in a second direction orthogonal to the axial direction and the first direction.

According to the third aspect, the first restricting portion restricts movement of the cylindrical portion in the first direction and the second direction. Therefore, the tubular portion is prevented from endlessly moving in the first direction and the second direction, and collision between the tubular portion and other members (for example, the housing or the accommodating portion) can be prevented.

A fourth aspect is characterized in that, in the second aspect or the third aspect, the first restricting portion includes an inner first restricting portion located inside the cylindrical portion.

According to the fourth aspect, the inner first restricting portion can restrict movement of the tubular portion in the first direction while the tubular portion is movable in the first direction. As a result, there is no need to provide a member for restricting the movement of the tubular portion in the first direction outside the tubular portion, and the space for this can be omitted, thereby suppressing an increase in the size of the flavor inhaler. .

In a fifth embodiment, in the fourth embodiment, when the inner diameter of the cylindrical portion is D1 and the diameter of a virtual circle circumscribing the inner first restricting portion when viewed from the axial direction of the cylindrical portion is D2, The gist is that D1>D2.

According to the fifth aspect, a gap is provided between the inner first restricting portion and the tubular portion when the inner first restricting portion is arranged inside the tubular portion. Thereby, while the tubular portion is movable in the first direction, the movement of the tubular portion in the first direction can be restricted by the inner first restricting portion. In this specification, the inner diameter of the cylindrical portion when the cylindrical portion is not cylindrical such as a square tube means the diameter of an imaginary circle inscribed in the inner surface of the cylindrical portion.

The gist of the sixth embodiment is that in the fifth embodiment, the difference between D1 and D2 is 1 mm or less.

According to the sixth aspect, the inner first restricting portion can be substantially loosely fitted inside the cylindrical portion. As a result, the space required for movement of the tubular portion can be reduced while the tubular portion is movable in the first direction. As a result, an increase in size of the flavor inhaler can be suppressed. In addition, since the movable range of the tubular portion can be reduced, the position of the tubular portion in the flavor inhaler is suppressed from being largely deviated from the designed position, and the performance of the flavor inhaler is improved according to the design. Deviations from performance are suppressed. Moreover, damage to the tubular portion due to the tubular portion swinging greatly is suppressed.

A seventh embodiment is the fifth embodiment or the sixth embodiment, wherein the inner first restricting portion has at least two protrusions projecting in the first direction, and the virtual circle is formed on the at least two protrusions. The gist is to circumscribe.

According to the seventh aspect, since the projection of the inner first restricting portion circumscribes the virtual circle, the projection can come into contact with the inner surface of the cylindrical portion. That is, the inner first restricting portion does not contact the entire inner surface of the cylindrical portion. Therefore, it is possible to suppress the heat of the inner first restricting portion from being transferred to the tubular portion, as compared with the case where the inner first restricting portion is in contact with the entire inner surface of the tubular portion. Therefore, especially when the accommodating portion is heated, the inner first restricting portion, which is closer to the accommodating portion than the tubular portion, is restrained from transferring heat to the tubular portion. is suppressed.

An eighth embodiment is the seventh embodiment, wherein the convex portion has a top portion having a shape corresponding to the inner surface of the cylindrical portion when viewed from the axial direction, and the virtual circle circumscribes the top portion and The gist is that L1>L2, where L1 is the circumferential length of the inner surface of the cylindrical portion and L2 is the total length of the portion of the top portion that circumscribes the imaginary circle.

According to the eighth aspect, the inner first restricting portion does not contact the entire circumference of the inner surface of the cylindrical portion. Therefore, it is possible to suppress the heat of the inner first restricting portion from being transferred to the tubular portion, as compared with the case where the inner first restricting portion is in contact with the entire inner surface of the tubular portion. Therefore, especially when the accommodating portion is heated, the inner first restricting portion, which is closer to the accommodating portion than the tubular portion, is restrained from transferring heat to the tubular portion. is suppressed.

The gist of the ninth form is that in the eighth form, L1 and L2 satisfy L2<0.5×L1.

According to the ninth form, it is possible to further reduce the area of contact between the inner first restricting portion and the inner surface of the cylindrical portion. As a result, it is possible to suppress the heat from the inner first restricting portion from being transferred to the cylindrical portion. Therefore, especially when the accommodating portion is heated, the inner first restricting portion, which is closer to the accommodating portion than the tubular portion, is more inhibited from transmitting heat to the tubular portion. Diffusion to the outside is further suppressed.

A tenth aspect is characterized in that, in any one of the fourth to sixth aspects, the inner first restricting portion has an annular portion positioned between the accommodating portion and the cylindrical portion.

According to the tenth form, when the cross-sectional shape of the inner surface of the tubular portion is the same annular shape as the annular portion, the annular portion can contact the inner surface of the tubular portion over a relatively large area. Therefore, when the tubular portion comes into contact with the annular portion, the impact applied from the annular portion to the tubular portion is dispersed, and it is possible to prevent the tubular portion from breaking.

According to an eleventh embodiment, in the tenth embodiment, the annular portion has an outer peripheral surface facing the inner surface of the tubular portion, and the outer peripheral surface has an outer diameter toward the center of the tubular portion in the axial direction. The gist of the invention is that it includes a tapered surface such that the

According to the eleventh form, when the annular portion is arranged inside the tubular portion, the annular portion can be easily inserted into the tubular portion.

A twelfth aspect is characterized in that, in any one of the second to eleventh aspects, the first restricting portion includes an outer first restricting portion located outside the cylindrical portion.

According to the twelfth aspect, since the outer first restricting portion is positioned outside the tubular portion, the tubular portion is positioned at the first position without providing a member for restricting the movement of the tubular portion inside the tubular portion. and the outer first restricting portion can restrict the movement of the cylindrical portion in the first direction. As a result, especially when the containing portion is heated, heat can be transferred to the cylindrical portion by not providing a member for restricting the movement of the cylindrical portion at a position closer to the containing portion than the cylindrical portion. Therefore, it is possible to suppress the heat of the housing portion from dissipating to the outside. When the first restricting portion includes the inner first restricting portion and the outer first restricting portion, both the inner first restricting portion and the outer first restricting portion can restrict the movement of the cylindrical portion in the first direction. can. That is, when the tubular portion moves in the first direction, both the inner first restricting portion and the outer first restricting portion simultaneously contact the tubular portion to restrict the movement of the tubular portion. It is possible to disperse the impact when the first restricting portion comes into contact with the cylindrical portion, thereby suppressing the destruction of the cylindrical portion.

A thirteenth embodiment is the twelfth embodiment that quotes any one of the fourth to eleventh embodiments, wherein the inner first restricting portion and the outer first restricting portion are arranged at overlapping positions in the axial direction. is the gist.

According to the thirteenth form, both the inner first restricting portion and the outer first restricting portion can restrict the movement of the tubular portion in the first direction at the same position in the axial direction. Therefore, the impact when the first restricting portion comes into contact with the cylindrical portion is dispersed at the same position in the axial direction, and it is possible to suppress the destruction of the cylindrical portion.

In a fourteenth embodiment, in the thirteenth embodiment, a gap in the first direction is formed between the inner first restricting portion and the outer first restricting portion, and the cylindrical portion is accommodated in the gap. The gist is that

According to the fourteenth form, the tubular portion can be positioned in the gap in the first direction and held in the gap so as to be movable in the first direction. In other words, the tubular portion is sandwiched without being fixed by the inner first restricting portion and the outer first restricting portion.

A fifteenth embodiment is any one of the second to fourteenth embodiments, wherein the cylindrical portion has a first end and a second end opposite to the first end, and the The gist is that the 1 restricting portion is arranged inside or outside at least one of the first end portion and the second end portion of the cylindrical portion in the first direction.

A sixteenth form is the fifteenth form, wherein the first restricting portion is arranged inside or outside of both the first end and the second end of the cylindrical portion in the first direction. is the gist.

According to the sixteenth aspect, since movement in the first direction can be restricted at two locations, the first end and the second end, of the cylindrical portion, the movement of the cylindrical portion can be performed without limit in the first direction at both ends of the cylindrical portion. Movement can be prevented, and collision between the tubular portion and other members (for example, the housing or the accommodating portion) can be prevented more reliably. Moreover, the impact when the first restricting portion comes into contact with the cylindrical portion is dispersed to both ends, and it is possible to suppress the destruction of the cylindrical portion.

A seventeenth aspect is characterized in that, in any one of the first to sixteenth aspects, the cylindrical portion has a base portion and a heat insulating layer provided on an outer peripheral surface of the base portion.

According to the seventeenth form, it is possible to suppress breakage of the base and the heat insulating layer. In particular, when the heat insulating layer is formed of a fragile material such as an airgel sheet, the heat insulating layer is supported by the base, and the base can be held so that the holding portion does not come into contact with the heat insulating layer.

The eighteenth mode is the seventeenth mode that refers to the fourteenth mode, wherein at one end of the cylindrical portion, the base has a protrusion that protrudes axially from the heat insulating layer, and the protrusion extends from the gap. The gist of it is that it is housed in

According to the 18th form, the movement in the first direction is restricted by the inner first restricting portion and the outer first restricting portion of the base portion that constitutes the cylindrical portion. Therefore, by forming the base from a material having a predetermined strength, for example, a resin such as PEEK, it is possible to suppress breakage of the tubular portion.

The gist of the nineteenth mode is that, in the seventeenth mode that quotes any one of the twelfth to fourteenth modes, the outer first restricting portion does not come into contact with the heat insulating layer.

According to the nineteenth form, since the first outer restricting portion does not directly apply impact to the heat insulating layer, even if the heat insulating layer is formed of a fragile material such as an airgel sheet, the breakage of the heat insulating layer is prevented. can be prevented.

A twentieth embodiment is any one of the first to nineteenth embodiments, wherein the housing portion has a cylindrical side wall portion, and the side wall portion has a cylindrical shape when the consumable material is stored in the housing portion. a contact portion that contacts the consumable material; and a separation portion that is adjacent to the contact portion in the circumferential direction and is spaced apart from the consumable material. The gist is that an air flow path is formed between the consumable material and the end surface of the consumable material in the container and the opening of the container.

According to the twentieth form, the air supplied from the opening of the container can reach the user's mouth through the air flow path and the end surface of the consumable. Since there is no need to separately provide a flow path in the flavor inhaler, the structure of the flavor inhaler can be simplified.

A 21st embodiment is any one of the 1st to 20th embodiments, further comprising a heating section disposed on the outer periphery of the storage section and configured to heat the consumable material stored in the storage section. is the gist.

When the consumables stored in the storage section are heated, the cylindrical section surrounding the storage section may expand due to the heat of the heating section. According to the twenty-first embodiment, even if the tubular portion expands due to the heat generated by the heating section, the tubular portion can expand into a space in which the tubular portion can move, thereby suppressing stress from being applied to the tubular portion. be able to.

A twenty-second embodiment is any one of the first to twenty-first embodiments, wherein the holding portion includes a second restricting portion that restricts movement of the cylindrical portion in the axial direction, and the holding portion is movably movable in the axial direction. The gist is that it is configured to hold the tubular portion.

According to the twenty-second embodiment, while the tubular portion is axially movable, axial movement can be restricted by the second restricting portion. Therefore, it is possible to prevent the tubular portion from infinitely moving in the axial direction, and prevent the tubular portion from colliding with other members (for example, the housing or the accommodating portion).

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.

FIG. 1A is a schematic front view of a flavor inhaler 100 according to this embodiment. FIG. 1B is a schematic top view of the flavor inhaler 100 according to this embodiment. FIG. 1C is a schematic bottom view of the flavor inhaler 100 according to this embodiment. In the drawings described in this specification, an XYZ orthogonal coordinate system may be attached for convenience of explanation. In this coordinate system, the Z axis points vertically upward, the XY plane is arranged to cut the flavor inhaler 100 horizontally, and the Y axis extends from the front to the back of the flavor inhaler 100. arranged to come out. The Z-axis can also be said to be the direction of insertion of consumables contained in the chamber 50 of the atomizing section 30, which will be described later, or the axial direction of the cylindrical heat insulating section. Also, the X-axis can be said to be a first direction perpendicular to the axial direction, and the Y-axis can also be said to be a second direction perpendicular to the axial direction and the first direction. The X-axis direction can also be said to be the longitudinal direction of the device in a plane perpendicular to the direction in which the consumable is inserted, or the direction in which the heating section and the power supply section are aligned. The Y-axis direction can also be said to be the lateral direction of the device in a plane perpendicular to the direction of insertion of the consumable.

The flavor inhaler 100 according to the present embodiment is configured to generate a flavor-containing aerosol by, for example, heating a stick-shaped consumable having a flavor source that includes the aerosol source.

As shown in FIGS. 1A to 1C, the flavor inhaler 100 has an outer housing 101 (corresponding to one example of a housing), a slide cover 102, and a switch section 103. Outer housing 101 forms the outermost housing of flavor inhaler 100 and is sized to fit in the user's hand. When the user uses the flavor inhaler 100, the user can hold the flavor inhaler 100 in his or her hand and inhale the aerosol. Outer housing 101 may be configured by assembling a plurality of members. The outer housing 101 can be made of resin such as PEEK (polyetheretherketone).

Outer housing 101 has an opening (not shown) for receiving consumables, and slide cover 102 is slidably attached to outer housing 101 so as to close this opening. Specifically, the slide cover 102 moves the outer housing 101 between a closed position (position shown in FIGS. 1A and 1B) for closing the opening of the outer housing 101 and an open position for opening the opening. It is configured to be movable along the surface. For example, the user can manually operate the slide cover 102 to move the slide cover 102 between the closed position and the open position. This permits or restricts access of consumables to the interior of the slide cover 102 and flavor inhaler 100 .

The switch section 103 is used to switch the operation of the flavor inhaler 100 between on and off. For example, by operating the switch unit 103 with the consumable material inserted into the flavor inhaler 100, the user can supply power from a power source (not shown) to a heating unit (not shown) to heat the consumable material without burning it. can be done. The switch portion 103 may be a switch provided outside the outer housing 101 or a switch positioned inside the outer housing 101 . When the switch is located inside the outer housing 101 , the switch is indirectly pressed by pressing the switch portion 103 on the surface of the outer housing 101 . In this embodiment, an example in which the switches of the switch section 103 are located inside the outer housing 101 will be described.

The flavor inhaler 100 may further have terminals (not shown). A terminal may be an interface that connects the flavor inhaler 100 to, for example, an external power source. When the power source provided in the flavor inhaler 100 is a rechargeable battery, by connecting an external power source to the terminal, the external power source can supply a current to the power source to charge the power source. The flavor inhaler 100 may also be configured to transmit data related to the operation of the flavor inhaler 100 to an external device by connecting a data transmission cable to the terminals.

Next, consumables used in the flavor inhaler 100 according to this embodiment will be described. FIG. 2 is a schematic side cross-sectional view of consumable 110 . In this embodiment, the flavor inhaler 100 and the consumable 110 may constitute a smoking system. In the example shown in FIG. 2 , consumable article 110 includes smokable article 111 , tubular member 114 , hollow filter portion 116 and filter portion 115 . A smokable article 111 is wrapped by a first wrapping paper 112 . The tubular member 114 , the hollow filter portion 116 and the filter portion 115 are wrapped with a second wrapping paper 113 different from the first wrapping paper 112 . The second wrapping paper 113 also wraps a portion of the first wrapping paper 112 that wraps the smokable article 111 . Thereby, the tubular member 114, the hollow filter portion 116, the filter portion 115 and the smokable article 111 are connected. However, second wrapping paper 113 may be omitted and first wrapping paper 112 may be used to connect tubular member 114, hollow filter portion 116, and filter portion 115 to smokable article 111. FIG. A lip release agent 117 is applied to the outer surface of the second wrapping paper 113 in the vicinity of the filter portion 115 side end to prevent the user's lips from sticking to the second wrapping paper 113 . A portion of the consumable product 110 to which the lip release agent 117 is applied functions as a mouthpiece for the consumable product 110 .

Smokables 111 may include flavor sources, such as tobacco, and aerosol sources. Also, the first wrapping paper 112 around which the smokable article 111 is wrapped may be a breathable sheet member. Tubular member 114 may be a paper tube or hollow filter. In the illustrated example, the consumable item 110 includes a smokable article 111, a tubular member 114, a hollow filter portion 116, and a filter portion 115, but the configuration of the consumable item 110 is not limited to this. For example, hollow filter portion 116 may be omitted, and cylindrical member 114 and filter portion 115 may be arranged adjacent to each other.

Next, the internal structure of the flavor inhaler 100 will be described. FIG. 3 is a cross-sectional view of flavor inhaler 100 taken along line 3-3 shown in FIG. 1B. As shown in FIG. 3 , an inner housing 10 (corresponding to one example of a housing) is provided inside an outer housing 101 of the flavor inhaler 100 . The inner housing 10 is made of, for example, a resin, particularly polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), or a polymer alloy containing a plurality of types of polymers, or It can be made of metal such as aluminum. From the viewpoint of heat resistance and strength, the inner housing 10 is preferably made of PEEK. However, the material of the inner housing 10 is not particularly limited. A power supply section 20 and an atomization section 30 are provided in the inner space of the inner housing 10 . Further, the outer housing 101 is made of, for example, a resin, particularly polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), or a polymer alloy containing a plurality of types of polymers. Alternatively, it may be made of metal such as aluminum.

The power supply unit 20 has a power supply 21 . Power source 21 may be, for example, a rechargeable battery or a non-rechargeable battery. Power supply 21 is electrically connected to atomization section 30 . Thereby, the power source 21 can supply power to the atomization section 30 so as to appropriately heat the consumable material 110 .

As shown in the figure, the atomization section 30 includes a chamber 50 (corresponding to an example of a storage section) extending in the insertion direction (Z-axis direction) of the consumable material 110, a heating section 40 surrounding a part of the chamber 50, and a heat-insulating section. It has a portion 32 (corresponding to an example of a cylindrical portion) and a substantially cylindrical insertion guide member 34 . Chamber 50 is configured to contain consumables 110 . The heating unit 40 is configured to contact the outer peripheral surface of the chamber 50 and heat the consumable material 110 accommodated in the chamber 50 . A bottom member 36 may be provided at the bottom of the chamber 50 as shown. Bottom member 36 may act as a stop to position consumable 110 inserted into chamber 50 . The bottom member 36 has unevenness on the surface with which the consumable material 110 abuts, and can define a space capable of supplying air to the surface with which the consumable material 110 abuts. The bottom member 36 may be made of, for example, a resin material such as PEEK, metal, glass, ceramic, or the like, but is not particularly limited to this. Also, the material forming the bottom member 36 may be a material having a lower thermal conductivity than the material forming the chamber 50 . When joining the bottom member 36 to the bottom portion 56 (see FIG. 6B) of the chamber 50, an adhesive that can be composed of a resin material such as epoxy resin or an inorganic material can be used. Details of the chamber 50 and the heating unit 40 will be described later.

The heat insulation part 32 has a generally cylindrical shape as a whole and is arranged so as to surround the chamber 50 . The heat insulating portion 32 may include, for example, an airgel sheet. The insertion guide member 34 is made of a resin material such as PEEK, PC, or ABS, and is provided between the slide cover 102 in the closed position and the chamber 50 . In this embodiment, since the insertion guide member 34 can come into contact with the chamber 50, the insertion guide member 34 is preferably made of PEEK from the viewpoint of heat resistance. The insertion guide member 34 communicates with the exterior of the flavor inhaler 100 when the slide cover 102 is in the open position, and inserting the consumable 110 into the insertion guide member 34 facilitates the insertion of the consumable 110 into the chamber 50 . to guide

As shown in FIGS.

As shown in FIG. 6, the heating section 40 has a heating element 42 . Heating element 42 may be, for example, a heating track. Heating element 42 is preferably arranged to heat contact portion 62 without contacting spaced portion 66 of chamber 50 . In other words, the heating element 42 is preferably arranged only on the outer surface of the contact portion 62 . The heating element 42 may have a different heating capacity between the portion that heats the spaced portion 66 of the chamber 50 and the portion that heats the contact portion 62 . Specifically, heating element 42 may be configured to heat contact portion 62 to a higher temperature than spacing portion 66 . For example, the density of the heating tracks of the heating elements 42 in the contact portion 62 and the spaced portion 66 can be adjusted. The heating element 42 may also be wrapped around the circumference of the chamber 50 with approximately the same heating capacity all around the circumference of the chamber 50 . As shown in FIG. 6, in addition to the heating element 42, the heating section 40 preferably has an electrical insulating member 44 covering at least one surface of the heating element 42. As shown in FIG. In this embodiment, the electrical insulation member 44 is arranged to cover both sides of the heating element 42 .

FIG. 7 is the cross-sectional view shown in FIG. 5B with consumable 110 in the desired position within chamber 50 . As shown in FIG. 7, once the consumable 110 is in the desired position within the chamber 50 , the consumable 110 can be pressed into contact with the contact portion 62 of the chamber 50 . On the other hand, a gap 67 is formed between the consumable material 110 and the spacing portion 66 . Gap 67 may communicate with opening 52 of chamber 50 and an end face of consumable 110 positioned within chamber 50 . This allows the air that has flowed in from the opening 52 of the chamber 50 to pass through the gap 67 and flow into the consumable 110 . In other words, an air flow path (gap 67 ) is formed between the consumable material 110 and the spacing portion 66 .

Next, the manner in which the heat insulating portion 32 is held in this embodiment will be described in detail. If the heat insulation part 32 surrounding the chamber 50 is completely fixed to the inner housing 10 or the outer housing 101, when the flavor inhaler 100 is subjected to an external shock, the shock cannot be buffered and the heat is insulated. There is a risk that the portion 32 will be destroyed. Moreover, when the heat insulating portion 32 expands due to the heat of the chamber 50 (or the heating portion 40), the fixed heat insulating portion may buckle due to the thermal expansion. Therefore, in the present embodiment, the flavor inhaler 100 holds the heat insulating part 32 movably in the axial direction of the chamber 50 or in a first direction (eg, the X-axis direction or the Y-axis direction) orthogonal to this axial direction. It has a first holding portion 37 and a second holding portion 38 (each of which corresponds to an example of a holding portion). In this specification, an example in which the first holding portion 37 and the second holding portion 38 hold the heat insulating portion 32 so as to be movable in the axial direction of the chamber 50 and the first direction will be described. It may be held so as to be movable only in the axial direction, or may be held so as to be movable only in the first direction. Also, the first holding portion 37 and the second holding portion 38 can be made of elastomer such as silicone rubber, for example.

As shown in FIG. 3 , the first holding portion 37 holds the terminal-side (Z-axis negative direction) first end portion 39 a of the heat insulating portion 32 movably in the axial direction of the chamber 50 or in the first direction. The second holding portion 38 holds the second end portion 39b of the heat insulating portion 32 on the slide cover 102 side (Z-axis positive direction side) so as to be movable in the axial direction of the chamber 50 or the first direction. That is, in this embodiment, the heat insulating portion 32 is not completely fixed, and the flavor inhaler 100 has space for the heat insulating portion 32 to move. Therefore, even if the heat from the heating unit 40 expands the heat insulating part 32, the heat insulating part 32 can expand in this space, and the buckling of the heat insulating part 32 can be suppressed. In addition, even if the flavor inhaler 100 is subjected to an external impact, the movement of the heat insulating portion 32 can absorb the impact, and the breakage of the heat insulating portion 32 can be suppressed.

FIG. 8 is an enlarged sectional view of the first holding portion 37. As shown in FIG. As shown, the bottom member 36 provided inside the bottom portion 56 of the chamber 50 has a shaft portion 36 a that protrudes outside the chamber 50 through a hole 56 a of the chamber 50 . The flavor inhaler 100 has a substantially cylindrical bottom member cap 72 that receives the shaft portion 36 a of the bottom member 36 . The bottom member cap 72 has a flange portion 72a at one end on the chamber 50 side.

The heat insulating portion 32 has a support member 32a (corresponding to an example of a base portion) and a heat insulating layer 32b provided on the outer peripheral side of the support member 32a. Here, the outer peripheral side of the support member 32a refers to the opposite side of the support member 32a facing the chamber 50 . The support member 32 a has, for example, a substantially cylindrical shape and is arranged so as to surround the chamber 50 . The support member 32a may be made of, for example, resin such as PEEK, metal such as stainless steel, paper, or glass. Not limited to this, the support member 32a may be formed of any material that can be tubular. The heat insulating layer 32b can be, for example, an airgel sheet. In this embodiment, the heat insulating layer 32b may be fixed to the outer surface of the support material 32a with an adhesive or the like. Also, the heat insulating layer 32b can be adhered or fixed to the outer surface of the support member 32a via a PI (polyimide) base material having silicone adhesive layers on both sides. The heat insulating part 32 may further have a heat-shrinkable tube 32c arranged on the outer surface of the heat insulating layer 32b. The shrinkable tube 32c can be made of thermoplastic resin such as PFA or FEP, for example. In this embodiment, the heat-shrinkable tube 32c is used for the purpose of maintaining the state in which the heat insulating layer 32b is in contact with the support material 32a, but the present invention is not limited to this, and any member capable of achieving the same purpose can be used. can be adopted. For example, an elastic tube or the like may be used instead of the heat-shrinkable tube 32c. A heat resistant tape (eg PI tape) or a coating (eg varnish) can be used as the elastic tube. As shown, in this embodiment, the support member 32a may have a protrusion 33 at one end of the heat insulating portion 32 that axially protrudes from the heat insulating layer 32b.

FIG. 9 is a cross-sectional view of the heat insulating portion 32 along the XY plane. As shown in FIG. 9, the supporting material 32a, the heat insulating layer 32b, and the heat-shrinkable tube 32c that constitute the heat insulating portion 32 are annular as a whole. The support member 32a has an inner diameter D1 and an outer diameter D4. In addition, the support member 32a has an inner circumferential length L1'. As shown in the figure, the heat insulating portion 32 has a cylindrical shape in the present embodiment, but it is not limited to this, and may have any shape such as a square tube shape.

Referring to FIG. 8, the first holding portion 37 includes a ring 80 (which corresponds to an example of a first restricting portion and an inner first restricting portion) and a heater cushion 74 (which corresponds to an example of a first restricting portion and an outer first restricting portion). equivalent to ), and The ring 80 overlaps the support member 32a of the heat insulating portion 32 in the axial direction and is located inside the support member 32a in the first direction. At least a portion of the heater cushion 74, specifically, a peripheral wall portion 75 shown in FIG. located outside of The ring 80 and the heater cushion 74 sandwich the heat insulating portion 32 with a gap therebetween, so that the heat insulating portion 32 can be moved in the first direction while restricting the movement of the heat insulating portion 32 in the first direction. Hold. Therefore, it is possible to prevent the heat insulating portion 32 from endlessly moving in the first direction and prevent the heat insulating portion 32 from colliding with other members (for example, the inner housing 10 or the chamber 50).

Next, details of the ring 80 will be described. 10 is a plan view of the ring 80. FIG. As shown in FIGS. 8 and 10, the ring 80 has an opening 80a into which the bottom member cap 72 is inserted, and can be sandwiched and fixed between the flange portion 72a of the bottom member cap 72 and the heater cushion 74. . As shown in FIG. 10, the ring 80 includes a ring body 81 defining an opening 80a and at least two (three in the illustrated example) projecting from the ring body 81 in a direction orthogonal to the axial direction of the chamber 50. It has a portion 82 , a convex portion 83 and a convex portion 84 . The projections 83 and 84 are provided at positions of −90° and +90° in the circumferential direction from the projection 82 with respect to the center of the opening 80a of the ring 80 in the plan view shown in FIG. Also, as shown in FIGS. 8 and 10, the ring 80 has a notch 85 to form a space for the electrode 48 of the heating section 40 to extend. By providing the notch portion 85 in the ring 80, the electrode 48 of the heating portion 40 can extend substantially parallel to the axial direction.

The convex portion 82, the convex portion 83, and the convex portion 84 each have a top portion 82a, a top portion 83a, and a top portion 83a having a shape corresponding to the inner surface of the support member 32a of the heat insulating portion 32 when viewed from the axial direction, that is, on the plane shown in FIG. and a top 84a. 10, the diameter of an imaginary circle circumscribing the projections 82, 83, and 84 of the ring 80 is diameter D21. In other words, this imaginary circle circumscribes apex 82a, apex 83a, and apex 84a.

Here, in the present embodiment, the diameter D21 of the virtual circle circumscribing the ring 80 is preferably smaller than the inner diameter D1 of the support member 32a of the heat insulating portion 32 (that is, preferably D1>D21). That is, a gap is provided between the ring 80 and the heat insulating portion 32 when the ring 80 is arranged inside the heat insulating portion 32 . As a result, while the heat insulating portion 32 is movable in the first direction, the heat insulating portion 32 moves in the first direction to come into contact with the ring 80, and the ring 80 restricts the movement of the heat insulating portion 32 in the first direction. be able to.

In addition, in the present embodiment, since the projections 82, 83, and 84 of the ring 80 circumscribe the virtual circle, these projections 82, 83, and 84 are the same as the heat insulating portion 32. It can contact the inner surface of the heat insulating portion 32 when moved in one direction. That is, the ring 80 does not contact the inner surface of the heat insulating portion 32 over the entire circumference. Therefore, it is possible to suppress the heat of the ring 80 from being transmitted to the heat insulating portion 32 as compared with the case where the ring 80 is in contact with the entire inner surface of the heat insulating portion 32 . Therefore, especially when the chamber 50 is heated, the ring 80 closer to the chamber 50 than the heat insulating portion 32 is suppressed from transmitting heat to the heat insulating portion 32, and as a result, the heat of the chamber 50 is dissipated to the outside. is suppressed.

The difference between the inner diameter D1 and the diameter D21 is preferably 1 mm or less. As a result, the ring 80 can be substantially loosely fitted inside the heat insulating portion 32, so that the space required for moving the heat insulating portion 32 can be reduced while the heat insulating portion 32 is movable in the first direction. As a result, an increase in size of the flavor inhaler 100 can be suppressed. In addition, since the movable range of the heat insulating part 32 can be reduced, the position of the heat insulating part 32 in the flavor inhaler 100 is suppressed from being displaced from the designed location, and the performance of the flavor inhaler 100 is improved. Deviations from the above performance are suppressed.

The length L2 is the sum of the circumferential lengths of the apex 82a, apex 83a, and apex 84a of the ring 80 (the length of the portion that circumscribes the virtual circle of the ring 80). is smaller than the circumferential length L1' (see FIG. 9) of the inner surface of the support member 32a (that is, it is preferable that L1'>L2). That is, it is preferable that the ring 80 does not contact the inner surface of the heat insulating portion 32 over the entire circumference. In this case, compared with the case where the ring 80 is in contact with the inner surface of the heat insulating portion 32 over the entire circumference, the heat of the ring 80 can be suppressed from being transferred to the heat insulating portion 32 .

Further, when the circumferential length of the imaginary circle circumscribing the ring 80 shown in FIG. It is preferably larger than the length L2, which is the sum of the length of the virtual circle and the circumscribed portion (that is, it is preferable that L1>L2). In this case, compared to the case where the outer circumference of the ring 80 is circular in plan view shown in FIG. It is possible to suppress the transmission. Therefore, especially when the chamber 50 is heated, the ring 80 closer to the chamber 50 than the heat insulating portion 32 is suppressed from transmitting heat to the heat insulating portion 32, and as a result, the heat of the chamber 50 is dissipated to the outside. is suppressed.

More preferably, the length L1 and the length L2 satisfy L1<0.5×L2. Thereby, the length of the portion where the ring 80 is close to the inner surface of the heat insulating portion 32 can be made shorter. As a result, it is possible to further suppress the heat of the ring 80 from being transferred to the heat insulating portion 32 . Moreover, it is most preferable that the length L1 and the length L2 satisfy 0.2×L2<L1<0.4×L2. If the length L1 is 0.2×L2 or less, the ring 80 may be deformed and the axes (central axes) of the chamber 50 and the heat insulating portion 32 may not be aligned. When the length L1 is 0.2×L2 and less than 0.4×L2, the axial position of the chamber 50 and the heat insulation portion 32 is properly maintained while the outflow of heat is more efficiently suppressed. be able to.

Since the ring 80 comes into contact with the convex portion 82 when the heat insulating portion 32 moves in an arbitrary first direction, it is possible to restrict the movement of the heat insulating portion 32 in the first direction. Also, the ring 80 preferably restricts movement in the axial direction and in a second direction perpendicular to the first direction. Specifically, the ring 80 has a convex portion 83 or a convex portion 84, and when the heat insulating portion 32 moves in the axial direction and the second direction orthogonal to the arbitrary first direction, the convex portion 83 or the convex portion Preferably, the portion 84 contacts the heat insulating portion 32 and restricts movement in the second direction as well. This prevents the heat insulating portion 32 from endlessly moving in the first direction and the second direction, and prevents the heat insulating portion 32 from colliding with other members (for example, the inner housing 10 or the chamber 50). .

In addition, since the ring 80 is positioned inside the heat insulating portion 32, a space for providing a member (for example, the heater cushion 74) that restricts the movement of the heat insulating portion 32 outside the heat insulating portion 32 can be omitted. An increase in the size of the suction device 100 can be suppressed.

Next, the heater cushion 74 will be explained. 11 is a plan view of the heater cushion 74. FIG. The heater cushion 74 may be made of an elastic material such as rubber. As shown in FIGS. 8 and 11, the heater cushion 74 has a central concave portion 74a, an annular convex portion 74b, a flat portion 74c, and a peripheral wall portion 75. As shown in FIGS. Central recess 74 a is configured to receive and support one end of bottom member cap 72 . The annular protrusion 74b defines a central recess 74a and axially sandwiches the ring 80 with the flange portion 72a of the bottom member cap 72 .

The flat portion 74c extends outward in the first direction while being spaced apart from the ring 80 from the annular convex portion 74b. The peripheral wall portion 75 extends in the Z-axis positive direction from the outermost periphery of the flat portion 74c and is positioned on the outer peripheral side of the projecting portion 33 of the support member 32a. As shown in FIG. 11, the diameter of an imaginary circle inscribed in the inner surface of the peripheral wall portion 75 of the heater cushion 74 when viewed from the axial direction is a diameter D3. In this embodiment, the diameter D3 is preferably larger than the outer diameter D4 of the support member 32a of the heat insulating portion 32 (that is, preferably D3>D4). In other words, a gap is provided between the support member 32 a and the peripheral wall portion 75 of the heater cushion 74 when the support member 32 a of the heat insulating portion 32 is arranged inside the peripheral wall portion 75 of the heater cushion 74 . As a result, while the heat insulating portion 32 is movable in the first direction, the heat insulating portion 32 contacts the peripheral wall portion 75 by moving in the first direction, and the heater cushion 74 prevents the heat insulating portion 32 from moving in the first direction. can be regulated.

A difference between the diameter D3 and the outer diameter D4 is preferably 1 mm or less. As a result, the support member 32a can be substantially loosely fitted inside the peripheral wall portion 75, so that the space required for movement of the heat insulating portion 32 can be reduced while the heat insulating portion 32 is movable in the first direction. . As a result, an increase in size of the flavor inhaler 100 can be suppressed. In addition, since the movable range of the heat insulating part 32 can be reduced, the position of the heat insulating part 32 in the flavor inhaler 100 is suppressed from being displaced from the designed location, and the performance of the flavor inhaler 100 is improved. Deviations from the above performance are suppressed.

Since the peripheral wall portion 75 of the heater cushion 74 is positioned outside the heat insulating portion 32 , the heat insulating portion 32 can be positioned at the outer side of the heat insulating portion 32 without providing a member (for example, a ring 80 ) for restricting the movement of the heat insulating portion 32 inside the heat insulating portion 32 . It can move in one direction, and the peripheral wall portion 75 can restrict the movement of the heat insulating portion 32 in the first direction. In particular, when the chamber 50 is heated, it is not necessary to provide a member (for example, the ring 80) that restricts movement of the heat insulating portion 32 at a position closer to the chamber 50 than the heat insulating portion 32 is. For this reason, heat is suppressed from being transferred to the heat insulating portion 32 via the member, and as a result, the heat of the chamber 50 is suppressed from radiating to the outside.

Moreover, when the ring 80 and the heater cushion 74 are provided as in the present embodiment, both the ring 80 and the heater cushion 74 can restrict the movement of the heat insulating portion 32 in the first direction. That is, when the heat insulating portion 32 moves in the first direction, both the ring 80 and the heater cushion 74 come into contact with the heat insulating portion 32 at the same time, thereby restricting the movement of the heat insulating portion 32 . Therefore, the impact when the ring 80 and the heater cushion 74 come into contact with the heat insulating portion 32 is dispersed, and the breakage of the heat insulating portion 32 can be suppressed. In this embodiment, the flavor inhaler 100 has the ring 80 and the peripheral wall portion 75 of the heater cushion 74, but it is not limited to this, and may have only one of them.

Moreover, as shown in FIG. 8, it is preferable that the ring 80 and the peripheral wall portion 75 of the heater cushion 74 are arranged to overlap each other in the axial direction. Thus, both the ring 80 and the heater cushion 74 can restrict the movement of the heat insulating portion 32 in the first direction at the same position in the axial direction. Therefore, the impact when the ring 80 and the heater cushion 74 come into contact with the heat insulating portion 32 is distributed at the same position in the axial direction, and the breakage of the heat insulating portion 32 can be suppressed.

Since the diameter D21 of the ring 80 is smaller than the diameter D3 of the imaginary circle of the peripheral wall portion 75, as shown in FIG. It is formed. The projecting portion 33 of the support member 32a is accommodated in this gap S1. Therefore, the projecting portion 33 of the support member 32a can be held movably in the first direction in the gap S1. In other words, the projecting portion 33 of the support member 32a is sandwiched between the ring 80 and the peripheral wall portion 75 without being fixed. Therefore, by forming the supporting member 32a from a material having a predetermined strength, for example, a resin such as PEEK, it is possible to prevent the heat insulating portion 32 from being destroyed.

Further, as shown in FIG. 8, the peripheral wall portion 75 is positioned so as not to come into contact with the heat insulating layer 32b of the heat insulating portion 32. As shown in FIG. As a result, the peripheral wall portion 75 does not directly apply impact to the heat insulating layer 32b, so even if the heat insulating layer 32b is formed of a fragile material such as an airgel sheet, the heat insulating layer 32b can be prevented from being destroyed. can be done.

The heater cushion 74 may have an end face support 76 that can contact the end face of the projection 33 of the support 32a. As will be described later, the end face support portion 76 of the heater cushion 74 can cooperate with the gasket 90 of the second holding portion 38 to axially movably hold the heat insulating portion 32 .

12A is an enlarged cross-sectional view of the second holding portion 38. FIG. FIG. 12B is an enlarged view of portion A shown in FIG. 12A. As shown in FIG. 12A, in this embodiment, the second retainer 38 includes a gasket 90 arranged around the tubular portion 54 of the chamber 50 . The gasket 90 includes an annular portion 92 arranged between the chamber 50 and the heat insulating portion 32 when viewed in the axial direction (Z-axis direction), and a flange portion 90 a having an outer diameter larger than that of the annular portion 92 . “Between the chamber 50 and the heat insulating portion 32” means the gap in the first direction between the chamber 50 and the heat insulating portion 32, and “located between the chamber 50 and the heat insulating portion 32” means the axial direction ( Z-axis direction) overlaps the chamber 50 and the heat insulating portion 32 and is sandwiched between the chamber 50 and the heat insulating portion 32 . The annular portion 92 has an outer peripheral surface 92a that faces the inner surface of the heat insulating portion 32, that is, the inner surface of the support member 32a.

FIG. 13 is a plan view of the gasket 90 viewed from the annular portion 92 side. As shown in FIG. 13, the diameter of an imaginary circle circumscribing the outer peripheral surface 92a of the annular portion 92 is defined as a diameter D22. Here, in this embodiment, the diameter D22 is preferably smaller than the inner diameter D1 (see FIG. 9) of the support member 32a of the heat insulating portion 32 (that is, preferably D1>D22). In other words, a gap is provided between the annular portion 92 and the heat insulating portion 32 when the annular portion 92 is arranged inside the heat insulating portion 32 . As a result, while the heat insulating portion 32 is movable in the first direction, the heat insulating portion 32 moves in the first direction to come into contact with the outer peripheral surface 92 a of the annular portion 92 , and the annular portion 92 causes the heat insulating portion 32 to move in the first direction. Directional movement can be restricted. Moreover, when the cross-sectional shape of the inner surface of the heat insulating portion 32 is the same annular shape as the annular portion 92 as in the present embodiment, the annular portion 92 can contact the inner surface of the heat insulating portion 32 over a relatively large area. Therefore, when the heat insulating portion 32 comes into contact with the annular portion 92 , the impact applied from the annular portion 92 to the heat insulating portion 32 is dispersed, and breakage of the heat insulating portion 32 can be suppressed.

A difference between the inner diameter D1 and the diameter D22 is preferably 1 mm or less. As a result, the annular portion 92 of the gasket 90 can be substantially loosely fitted inside the heat insulating portion 32, so that while the heat insulating portion 32 is movable in the first direction, the space required for movement of the heat insulating portion 32 is reduced. be able to. As a result, an increase in size of the flavor inhaler 100 can be suppressed. In addition, since the movable range of the heat insulating part 32 can be reduced, the position of the heat insulating part 32 in the flavor inhaler 100 is suppressed from being displaced from the designed location, and the performance of the flavor inhaler 100 is improved. Deviations from the above performance are suppressed.

Also, as shown in FIGS. 12A and 12B, the outer peripheral surface 92a of the annular portion 92 preferably includes a tapered surface 92a whose outer diameter decreases as it approaches the central portion of the chamber 50 in the axial direction. This makes it easier to insert the annular portion 92 into the heat insulating portion 32 when arranging the annular portion 92 inside the heat insulating portion 32 .

Further, in this embodiment, as shown in FIG. 12A, the flange portion 90a of the gasket 90 can come into contact with the end face of the support member 32a of the heat insulating portion 32. As shown in FIG. As shown in FIG. 12B, the support member 32a slightly protrudes toward the flange portion 90a from the heat insulating layer 32b. Therefore, when the flange portion 90a contacts the support member 32a, the flange portion 90a is configured not to contact the heat insulating layer 32b. The flange portion 90a of the gasket 90 and the end face support portion 76 of the heater cushion 74 shown in FIG. can be done. Specifically, the gasket is arranged such that the axial distance L3 between the flange portion 90a and the end face support portion 76 of the heater cushion 74 is greater than the axial length L4 of the support member 32a of the heat insulating portion 32. 90 and heater cushion 74 may be positioned. That is, in the present embodiment, distance L3>length L4. In the state shown in FIG. 12B, since the support member 32a is supported in contact with the end face support portion 76 of the heater cushion 74 shown in FIG. 8, a slight gap is formed between the support member 32a and the flange portion 90a. It is This allows the heat insulating portion 32 to move axially between the flange portion 90 a of the gasket 90 and the end face support portion 76 of the heater cushion 74 . Further, the axial movement of the heat insulating portion 32 is restricted by the flange portion 90 a and the end face support portion 76 . As a result, the heat insulating portion 32 is prevented from moving endlessly in the axial direction, and collision between the heat insulating portion 32 and other members (for example, the inner housing 10 or the chamber 50) can be prevented.

On the other hand, the gasket 90 and the heater are arranged such that the axial distance between the flange portion 90a and the end face support portion 76 of the heater cushion 74 is substantially the same as the axial length of the support member 32a of the heat insulating portion 32. A cushion 74 may be positioned. In this case, both ends of the support member 32a of the heat insulating portion 32 contact both the flange portion 90a and the end face support portion 76, respectively. Even in this case, although the frictional force from the flange portion 90a and the end face support portion 76 is applied to the support member 32a, the heat insulating portion 32 can move in the first direction.

In this embodiment, the ring 80 is arranged inside the first end portion 39a of the heat insulating portion 32, the peripheral wall portion 75 of the heater cushion 74 is arranged outside the first end portion 39a, and the second end portion 39a of the heat insulating portion 32 is arranged. A gasket 90 is placed inside the end 39b. As a result, the movement of the heat insulating portion 32 in the first direction can be restricted at the first end portion 39 a and the second end portion 39 b of the heat insulating portion 32 . Therefore, the end portions of the heat insulating portion 32 are prevented from endlessly moving in the first direction, and the collision between the heat insulating portion 32 and other members (for example, the inner housing 10 or the chamber 50) can be more reliably prevented. can be done. In addition, the impact when the ring 80, the heater cushion 74, or the gasket 90 comes into contact with the heat insulating portion 32 is distributed to both ends, and the breakage of the heat insulating portion 32 can be suppressed. However, the invention is not limited to this, and movement of the heat insulating portion 32 in the first direction is restricted at least one of the inside and outside of either the first end portion 39a or the second end portion 39b of the heat insulating portion 32. A member may be provided.
