[First Embodiment]
Hereinafter, the first embodiment of the present disclosure will be described with reference to the drawings. In the drawings described below, the same or corresponding components are designated by the same reference numerals and duplicated description will be omitted.

FIG. 1A is a schematic front view of the flavor aspirator 100 according to the first embodiment. FIG. 1B is a schematic top view of the flavor aspirator 100 according to the first embodiment. FIG. 1C is a schematic bottom view of the flavor aspirator 100 according to the first embodiment. In the drawings described herein, an XYZ Cartesian coordinate system may be added for convenience of explanation. In this coordinate system, the Z-axis points vertically upward, the XY planes are arranged to cut the flavor aspirator 100 horizontally, and the Y-axis extends from the front to the back of the flavor aspirator 100. It is arranged to be put out. The Z-axis can also be said to be the insertion direction of the consumable material housed in the chamber 50 of the atomization unit 30, which will be described later. Further, it can be said that the Y-axis is orthogonal to the insertion direction of the consumable material and is the direction in which the first wall 10a and the second wall 10b, which will be described later, face each other. Further, the X-axis direction can also be said to be the device longitudinal direction in the plane orthogonal to the insertion direction of the consumer goods. The Y-axis direction can also be said to be the device short-side direction in the plane orthogonal to the insertion direction of the consumer goods.

The flavor aspirator 100 according to the first embodiment is configured to generate an aerosol containing an aerosol by heating, for example, a stick-type consumable material having a flavor source containing an aerosol source.

As shown in FIGS. 1A to 1C, the flavor aspirator 100 has an outer housing 101 composed of a front cover 101A and a rear cover 101B, and a slide cover 102. The front cover 101A is an example of the external cover of the present disclosure.

The outer housing 101 constitutes the outermost housing of the flavor aspirator 100 and has a size that fits in the user's hand. When the user uses the flavor aspirator 100, the flavor aspirator 100 can be held by hand to suck the aerosol. Regarding the outer housing 101, here, the front cover 101A is formed of a resin such as polycarbonate, and the rear cover 101B is formed of a metal such as aluminum. However, the material of the outer housing 101 is not limited to these, and is, for example, made of resin, and in particular, polycarbonate (PC), ABS (Polyetherride-Styleene) resin, PEEK (polyetheretherketone), or a plurality of types. It shall be possible to arbitrarily select a polymer alloy containing a polymer or the like.

The outer housing 101 has an opening (not shown) for receiving consumable materials, and the slide cover 102 is slidably attached to the outer housing 101 so as to close this opening. Specifically, the slide cover 102 has an outer surface of the outer housing 101 between a closed position (position shown in FIGS. 1A and 1B) for closing the opening of the outer housing and an open position for opening the opening. It is configured to be movable along. 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. Thereby, the access of the consumable material to the inside of the slide cover 102 and the flavor aspirator 100 can be permitted or restricted.

1B and 1C show that the front cover 101A and the rear cover 101B have substantially the same thickness in the flavor aspirator 100, but the configuration of the outer housing 101 is not limited to this. It is also possible to configure one of the front cover 101A or the rear cover 101B to be thicker than the other.

The flavor aspirator 100 may further have a terminal (not shown). The terminal may be an interface that connects the flavor aspirator 100 to, for example, an external power source. When the power source included in the flavor aspirator 100 is a rechargeable battery, by connecting an external power source to the terminal, a current can be passed from the external power source to the power source to charge the power source. Further, by connecting a data transmission cable to the terminal, data related to the operation of the flavor aspirator 100 may be transmitted to an external device.

Next, the consumable material used in the flavor aspirator 100 according to the first embodiment will be described. FIG. 2 is a schematic side sectional view of the consumer material 110. In the first embodiment, the smoking system may be configured by the flavor aspirator 100 and the consumable material 110. In the example shown in FIG. 2, the consumable material 110 includes a smokeable substance 111, a tubular member 114, a hollow filter portion 116, and a filter portion 115. The smokeable material 111 is wrapped by the first wrapping paper 112. The tubular member 114, the hollow filter portion 116, and the filter portion 115 are wound by a second wrapping paper 113 different from the first wrapping paper 112. The second wrapping paper 113 also wraps a part of the first wrapping paper 112 that wraps the smokeable material 111. As a result, the cylindrical member 114, the hollow filter portion 116, and the filter portion 115 are connected to the smokeable substance 111. However, the second wrapping paper 113 may be omitted, and the tubular member 114, the hollow filter portion 116, and the filter portion 115 may be connected to the smokeable material 111 by using the first wrapping paper 112. A lip release agent 117 is applied to the outer surface of the second wrapping paper 113 in the vicinity of the end portion on the filter portion 115 side to prevent the user's lips from sticking to the second wrapping paper 113. The portion of the consumer material 110 to which the lip release agent 117 is applied functions as a mouthpiece of the consumer material 110.

The smokeable substance 111 may include, for example, a flavor source such as tobacco and an aerosol source. Further, the first wrapping paper 112 around which the smokeable material 111 is wrapped may be a breathable sheet member. The tubular member 114 can be a paper tube or a hollow filter. In the example shown in FIG. 2, the consumer material 110 includes a smokeable substance 111, a tubular member 114, a hollow filter unit 116, and a filter unit 115, but the configuration of the consumer material 110 is not limited to this. For example, the hollow filter portion 116 may be omitted, and the cylindrical member 114 and the filter portion 115 may be arranged adjacent to each other.

FIG. 3 is a front view of the flavor aspirator 100 from which the outer housing 101 is removed. FIG. 4 is a front view of the metal panel 12 alone. FIG. 5 is a front view of the flavor aspirator 100 from which the outer housing 101 and the metal panel 12 are removed.

As shown in FIG. 5, when the outer housing 101 and the metal panel 12 are removed, the inner housing 10 is exposed. The inner housing 10 houses an atomizing unit 30, a power supply unit 20, a Bluetooth (registered trademark) interface 28 connected to a circuit unit (not shown), and the like, which will be described later. It can be formed of PC), ABS (Acrylonitrile-Butadie-Style) resin, PEEK (polyetheretherketone), a polymer alloy containing a plurality of types of polymers, and the like. However, the material of the inner housing 10 is not limited to this. The inner housing 10 has a first wall 10a and a second wall 10b (see FIG. 12) facing each other in the Y-axis direction, and a side wall 10c connecting the first wall 10a and the second wall 10b. FIG. 5 shows the first wall 10a and the side wall 10c. The inner housing 10 to which the metal panel 12 is attached is an example of the housing of the present disclosure.

The metal panel 12 has a thermal conductivity higher than that of the inner housing 10, and is provided so as to cover the first wall 10a of the inner housing 10. The metal panel 12 may be made of, for example, aluminum or the like. Further, the metal panel 12 may be in the form of a sheet. The metal panel 12 may be provided in close proximity to or in contact with the first wall 10a of the inner housing 10 and the ends of the side wall 10c. Specifically, for example, the metal panel 12 may be attached to the first wall 10a of the inner housing 10. Since the metal panel 12 having high thermal conductivity functions as a heat diffusing member for diffusing the heat transferred from the inner housing 10, the heat generated in the atomizing portion 30 can be diffused inside the flavor aspirator 100. The metal panel 12 is an example of the metal part of the present disclosure. Further, the pair of the metal panel 12 and the first wall 10a is an example of the first wall of the present disclosure.

As shown in FIGS. 3 and 4, the metal panel 12 is provided with an opening 14 at the lower portion in the Z-axis direction. Therefore, as shown in FIG. 3, a part of the first wall 10a of the inner housing 10 is exposed from the opening 14 of the metal panel 12. As will be described later, in the first wall 10a of the inner housing 10, the portion exposed from the opening 14 of the metal panel 12 includes a region corresponding to the Bluetooth interface 28 housed in the inner housing 10.

As will be described later, the shape and size of the opening 14 can be appropriately determined under the condition that the metal panel 12 according to the first embodiment does not cover the Bluetooth interface 28. However, as the area of the metal panel 12 increases, the effect of the metal panel 12 dissipating heat improves. Therefore, it is preferable that the metal panel 12 is provided so as to cover 50% or more of the area of the outer surface of the inner housing 10. According to the first embodiment, since the metal panel 12 covers the first wall 10a except for the opening 14, the heat from the atomizing portion 30 reaching the first wall 10a is diffused by the metal panel 12, and the inner housing is used. It is possible to prevent 10 from becoming locally hot.

As will be described later, since the atomizing portion 30 generates heat in the inner housing 10, the vicinity of the atomizing portion 30 tends to be locally hot on the first wall 10a. Therefore, it is preferable that the metal panel 12 covers at least a part of the region corresponding to the atomizing portion 30 housed in the inner housing 10 on the first wall 10a of the inner housing 10.

Next, the internal structure of the flavor aspirator 100 will be described. FIG. 6 is a cross-sectional view of the flavor aspirator 100 in arrow view 6-6 shown in FIG. 1B. FIG. 7 is a simplified cross-sectional view of the flavor aspirator 100 cut along a cross section orthogonal to the X-axis including the Bluetooth interface 28.

As shown in FIG. 6, a power supply unit 20 and an atomizing unit 30 are provided in the internal space of the inner housing 10 of the flavor aspirator 100. Further, a circuit portion (not shown) is provided in the internal space of the inner housing 10.

The circuit unit includes, for example, a microprocessor and the like, and can control the supply of electric power from the power supply unit 20 to the atomization unit 30. Thereby, the circuit unit can control the heating of the consumable material 110 by the atomizing unit 30. Further, the circuit unit is electrically connected to the Bluetooth interface 28. The Bluetooth interface 28 is an example of the communication unit of the present disclosure.

The flavor aspirator 100 of the first embodiment can communicate with an external device via the Bluetooth interface 28.

Here, the region covering the Bluetooth interface 28 in the first wall 10a of the inner housing 10 shown in FIG. 5 constitutes a part of the region exposed from the opening 14 of the metal panel 12 shown in FIG. The Bluetooth interface 28 is located in the positive direction of the Y axis with respect to a part of the first wall 10a exposed from the opening 14 in FIG. That is, in front view of the flavor aspirator 100, the Bluetooth interface 28 is not covered by the metal panel 12. Therefore, although the metal member generally interferes with electromagnetic waves, the flavor aspirator 100 can execute communication with an external device by the Bluetooth interface 28 through at least a region exposed from the opening 14 of the metal panel 12.

The details of the mutual arrangement between the metal panel 12 and the Bluetooth interface 28 according to the first embodiment will be described with reference to FIG. 7. For convenience of explanation, FIG. 7 omits the illustration of the inner housing 10 and the members housed in the inner housing 10 excluding the Bluetooth interface 28.

As shown in FIG. 7, the region defined by the angle range of 45 degrees to the left and right with the straight line parallel to the Y axis from the center of the Bluetooth interface 28 toward the front of the flavor aspirator 100 as a reference straight line is a metal panel. It is exposed from the opening 14 of the twelve. The cross section shown in FIG. 7 is an example of a cross section perpendicular to the X axis including the Bluetooth interface 28, and different cross sections can be selected along the X axis. In this case, the position of the center of the Bluetooth interface 28 in a plane parallel to the YZ plane may not be the same as in FIG. 7 in the selected cross section. However, in any of the cross sections, the region defined by the angle range of 45 degrees to the left and right of the reference straight line is exposed from the opening 14 of the metal panel 12. However, when the Bluetooth interface 28 has a protrusion or the like that does not function as an electromagnetic wave transmitting / receiving antenna, the portion consisting of only the protrusion or the like is defined by the center of the Bluetooth interface 28 and the reference straight line. The conditions regarding the area do not apply. That is, when the Bluetooth interface 28 includes a protrusion that does not substantially contribute to the transmission and reception of electromagnetic waves due to design reasons, it is not necessary for this protrusion to satisfy the condition shown in FIG. 7. The above-mentioned reference straight line and the angle range defined around it are determined based on the portion that substantially contributes to the transmission and reception of electromagnetic waves.

In the flavor aspirator 100 of the first embodiment, the region defined by the above-mentioned angle range is secured as a route used for communication with an external device by the Bluetooth interface 28.

The power supply unit 20 has a power supply 21 that is electrically connected to a circuit unit (not shown). 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 unit 30 via the circuit unit. As a result, the power supply 21 can supply electric power to the atomizing unit 30 so as to appropriately heat the consumable material 110.

As shown in FIG. 6, the atomizing portion 30 includes a chamber 50 extending in the longitudinal direction of the consumable material 110, a heating portion 40 surrounding a part of the chamber 50, a heat insulating portion 32, and a substantially tubular insertion guide member 34. And have. The chamber 50 is configured to accommodate the consumable material 110. The heating unit 40 is configured to come into contact with the outer peripheral surface of the chamber 50 and heat the consumable material 110 housed in the chamber 50. The chamber 50 and the heating unit 40 will be described in detail.

The heat insulating portion 32 is arranged so as to surround the chamber 50 and the heating portion 40. The heat insulating portion 32 can be, for example, airgel. The insertion guide member 34 is made of a resin material such as PEEK, PC, ABS, or the like, and is provided between the slide cover 102 in the closed position and the chamber 50. The insertion guide member 34 communicates with the outside of the flavor aspirator 100 when the slide cover 102 is in the open position, and inserts the consumable material 110 into the insertion guide member 34 to insert the consumable material 110 into the chamber 50. To guide you.

The flavor aspirator 100 further has a first support portion 37 and a second support portion 38 that support both ends of the chamber 50 and the heat insulating portion 32. The first support portion 37 is arranged so as to support the ends of the chamber 50 and the heat insulating portion 32 on the slide cover 102 side (Z-axis positive direction side). The second support portion 38 is arranged so as to directly or indirectly support the ends of the chamber 50 and the heat insulating portion 32 on the negative side of the Z axis. Further, as shown in FIG. 6, a bottom member 36 may be provided at the bottom of the chamber 50. The bottom member 36 can function as a stopper for positioning the consumable material 110 inserted into the chamber 50. The bottom member 36 may define a space in which air can be supplied to the surface with which the consumable material 110 abuts. The bottom member 36 has irregularities on the surface with which the consumer material 110 abuts, and may be formed of, for example, a resin material such as PEEK, metal, glass, ceramic, or the like, but is not limited thereto. Further, the first support portion 37 and the second support portion 38 can be formed of, for example, an elastomer such as silicone rubber. Further, when the bottom member 36 is joined to the bottom of the chamber 50, an adhesive that can be composed of a resin material such as an epoxy resin or an inorganic material can be used.

Next, the structure of the chamber 50 will be described. FIG. 8A is a perspective view of the chamber 50.

The bottom member 36 provided on the bottom 56 supports a part of the consumable material 110 inserted into the chamber 50 so as to expose at least a part of the end face of the consumable material 110. Further, the bottom portion 56 may support a part of the consumable material 110 so that the end face of the exposed consumable material 110 communicates with the void 67 (see FIG. 11) described later.

As shown in FIGS. 8A and 8B, the chamber 50 preferably has a cylindrical non-holding portion 54 between the opening 52 and the side wall portion 60. With the consumable material 110 positioned at the desired position in the chamber 50, a gap may be formed between the non-holding portion 54 and the consumable material 110. Further, as shown in FIGS. 8A and 8B, it is preferable that the chamber 50 has a first guide portion 58 provided with 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. 10, the heating unit 40 has a heating element 42. The heating element 42 may be, for example, a heating track. It is preferable that the heating element 42 is arranged so as to heat the contact portion 62 without contacting the separation portion 66 of the 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 difference in heating capacity between the portion that heats the separated portion 66 of the chamber 50 and the portion that heats the contact portion 62. Specifically, the heating element 42 may be configured to heat the contact portion 62 to a higher temperature than the separation portion 66. For example, the placement density of the heating track of the heating element 42 at the contact portion 62 and the separation portion 66 may be adjusted. Further, the heating element 42 may have substantially the same heating capacity all around the chamber 50 and may be wound around the outer periphery of the chamber 50. As shown in FIG. 10, it is preferable that the heating unit 40 has, in addition to the heating element 42, an electrical insulating member 44 that covers at least one surface of the heating element 42. In the first embodiment, the electrical insulating member 44 is arranged so as to cover both sides of the heating element 42.

FIG. 11 is a cross-sectional view shown in FIG. 9B in a state where the consumable material 110 is arranged at a desired position in the chamber 50. As shown in FIG. 11, when the consumable material 110 is placed at a desired position in the chamber 50, the consumable material 110 can come into contact with and be pressed against the contact portion 62 of the chamber 50. On the other hand, a gap 67 is formed between the consumable material 110 and the separation portion 66. The void 67 can communicate with the opening 52 of the chamber 50 and the end face of the consumable material 110 located in the chamber 50. As a result, the air flowing in from the opening 52 of the chamber 50 can pass through the gap 67 and flow into the inside of the consumable material 110. In other words, an air flow path (void 67) is formed between the consumable material 110 and the separation portion 66.

Next, the arrangement position and arrangement mode of the atomizing portion 30 in the inner housing 10 will be described. FIG. 12 is a partial cross-sectional view of the flavor aspirator 100 in arrow view 12-12 shown in FIG. 1B.

As described above, in the first embodiment, since the air flow path (void 67) is formed between the separation portion 66 and the consumable material 110, the air passing through the air flow path absorbs the heat of the separation portion 66. The separation portion 66 can be cooled.

As described above, the heating element 42 of the heating unit 40 is arranged so as to heat the contact portion 62 without contacting the separation portion 66 of the side wall portion 60 of the chamber 50. That is, since the separating portion 66 is not directly heated by the heating portion 40, heating by the heating portion 40 of the separating portion 66 can be suppressed.

As shown in FIG. 12, the outer housing 101 accommodates the inner housing 10 inside. The inner surface (the surface on the positive direction side of the Y axis) of the front cover 101A of the outer housing 101 faces the outer surface (the surface on the negative direction side of the Y axis) of the first wall 10a of the inner housing 10 via the metal panel 12. Since the first wall 10a of the inner housing 10 is covered by the front cover 101A of the outer housing 101, the heat transmitted from the atomizing portion 30 to the first wall 10a of the inner housing 10 is transferred to the outside of the flavor aspirator 100. It can be suppressed from being transmitted. As a result, when the user grips the flavor aspirator 100, it is possible to prevent the user from feeling a sense of discomfort.

[Second Embodiment]
Hereinafter, the second embodiment of the present disclosure will be described. The parts having the same configuration as that of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 13 is a front view of the flavor aspirator 200 according to the second embodiment in which the outer housing 101 is removed. FIG. 14 is a front view of the metal panel 212 alone. FIG. 15 is a simplified cross-sectional view of the flavor aspirator 200 cut along a cross section orthogonal to the X-axis including the Bluetooth interface 28.

The flavor aspirator 200 according to the second embodiment is different from the flavor aspirator 100 according to the first embodiment in the configuration of the metal panel 212. That is, in the flavor aspirator 200 according to the second embodiment, instead of the metal panel 12 of the first embodiment shown in FIG. 4, the metal panel 212 shown in FIG. 14 is the first wall 10a of the inner housing 10. It is provided so as to cover the. The metal panel 212 according to the second embodiment is another example of the metal portion of the present disclosure.

As shown in FIGS. 3 and 4, the metal panel 12 according to the first embodiment has an opening 14 at the lower portion in the Z-axis direction. On the other hand, as shown in FIG. 14, the metal panel 212 according to the second embodiment does not have an opening, is cut near the center in the Z-axis direction, and does not extend to the lower portion in the Z-axis direction. It is configured. The solid line shown in FIG. 13 to divide the flavor aspirator 200 in the horizontal direction (direction parallel to the X-axis) represents the lower end portion 212A of the metal panel 212. Therefore, in FIG. 13, the first wall 10a and the side wall 10c of the inner housing 10 are exposed in the portion below the lower end portion 212A of the metal panel 212.

Similar to the first embodiment, from the viewpoint of heat diffusion efficiency, the metal panel 212 according to the second embodiment is preferably provided so as to cover 50% or more of the area of the outer surface of the inner housing 10. As shown in FIG. 6, the heat-generating atomizing portion 30 is arranged in the inner housing 10 at the upper part in the Z-axis direction. According to the second embodiment, since the metal panel 212 covers the upper part in the Z-axis direction corresponding to the atomized portion of the first wall 10a, the heat from the atomized portion 30 reaching the first wall 10a is generated by the metal panel 212. It is possible to prevent the inner housing 10 from becoming locally hot due to diffusion.

On the other hand, as shown in FIG. 6, the Bluetooth interface 28 is arranged in the inner housing 10 at the lower part in the Z-axis direction. The Bluetooth interface 28 is located in the positive direction of the Y-axis with respect to a part of the first wall 10a that is located and exposed below the lower end portion 212A of the metal panel 212 in the Z-axis direction in FIG. That is, in front view of the flavor aspirator 200, the Bluetooth interface 28 is not covered by the metal panel 212. Therefore, although the metal member generally interferes with the electromagnetic wave, the flavor aspirator 200 can execute communication with an external device by the Bluetooth interface 28 through at least a region not covered by the metal panel 212.

With reference to FIG. 15, the details of the mutual arrangement between the metal panel 212 and the Bluetooth interface 28 according to the second embodiment will be described. For convenience of explanation, FIG. 15 omits the illustration of the inner housing 10 and the members housed in the inner housing 10 excluding the Bluetooth interface 28.

As shown in FIG. 15, the region defined by the angle range of 45 degrees to the left and right with the straight line parallel to the Y axis from the center of the Bluetooth interface 28 toward the front of the flavor aspirator 100 as a reference straight line is a metal panel. It is located in the negative direction of the Z axis with respect to the lower end portion 212A of 212. The cross section shown in FIG. 15 is an example of a cross section perpendicular to the X axis including the Bluetooth interface 28, and different cross sections can be selected along the X axis. In this case, the position of the center of the Bluetooth interface 28 in a plane parallel to the YZ plane may not be the same as in FIG. 15 in the selected cross section. However, in any of the cross sections, the region defined by the angle range of 45 degrees to the left and right of the reference straight line is located in the negative direction of the Z axis with respect to the lower end portion 212A of the metal panel 212. However, as in the first embodiment, when the Bluetooth interface 28 includes a protrusion or the like that does not function as an electromagnetic wave transmitting / receiving antenna, the portion consisting only of the protrusion or the like is the center and the reference of the above-mentioned Bluetooth interface 28. The conditions for the above area defined from the straight line do not apply. That is, when the Bluetooth interface 28 includes a protrusion that does not substantially contribute to the transmission and reception of electromagnetic waves due to design reasons, it is not necessary for this protrusion to satisfy the condition shown in FIG. Similar to the first embodiment, the above-mentioned reference straight line and the angle range defined around the reference straight line are determined based on the portion substantially contributing to the transmission and reception of electromagnetic waves.

In the flavor aspirator 200 of the second embodiment, the region defined by the above-mentioned angle range is secured as a route used for communication with an external device by the Bluetooth interface 28.

Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments, and various modifications are made within the scope of claims and the technical ideas described in the specification and drawings. Is possible. It should be noted that any shape or material not directly described in the specification or drawings is within the scope of the technical idea of the present disclosure as long as it exerts the effect of the present disclosure. For example, the flavor aspirator 100 of the present disclosure has a so-called counterflow type air flow path in which air flowing in from the opening 52 of the chamber 50 is supplied to the end face of the consumer material 110, but the chamber 50 is not limited to this. It may have a so-called bottom flow type air flow path in which air is supplied from the bottom portion 56 of the chamber 50 into the chamber 50. Further, the heating element 42 is not limited to the resistance heating type, and may be an induction heating type. In that case, the heating element 42 can heat the chamber 50 by induction heating. Further, when the consumption material 110 has a susceptor, the heating element 42 can heat the susceptor of the consumption material 110 by induction heating.
