[0005] PTL 1: WO 2020 / 199210 A1 Summary of the Invention

[0006] Technical Problem

[0007] In the flavor inhaler disclosed in PTL 1, when a control unit that controls the operation of the flavor inhaler is arranged adjacent to the housing part, the heat of the housing part diffused by the heat diffusion part may undesirably affect the control unit.

[0008] The present invention has been designed to solve at least some of the above problems, and an object thereof is to use a heat diffusion part to diffuse the heat of a housing part while protecting a control unit from the heat of the housing part.

[0009] Solution to the Problem

[0010] In a first aspect of the present invention, there is provided a flavor inhaler. The flavor inhaler includes: a cylindrical housing part that houses a consumable material to heat the consumable material; a heat diffusion part that is arranged to cover at least a part of the housing part and diffuses the heat of the housing part; a control unit that controls the operation of the flavor inhaler; and a housing that houses the housing part, the heat diffusion part, and the control unit, wherein the housing part and the control unit are arranged adjacent to each other in a direction orthogonal to the longitudinal direction of the flavor inhaler, and a part of the heat diffusion part on the control unit side is open in the circumferential direction of the housing part.

[0011] According to the first aspect of the present invention, the heat diffusion part that covers the housing part has a part that is open in the circumferential direction of the housing part on the control unit side. Therefore, the heat of the housing part can be diffused by the heat diffusion part while protecting the control unit from the heat of the housing part.

[0012] According to a second aspect of the present invention (which second aspect is based on the first aspect), the heat diffusion portion is configured to extend beyond the accommodation portion toward the control unit.

[0013] According to the second aspect of the present invention, by configuring the heat diffusion portion to extend beyond the accommodation portion toward the control unit, heat diffusion in the radial direction of the accommodation portion can be promoted.

[0014] According to a third aspect of the present invention (which third aspect is based on the first aspect or the second aspect), the control unit has a control board, and the heat diffusion portion is arranged not to cover at least one main surface of the control board.

[0015] According to the third aspect of the present invention, by arranging the heat diffusion portion not to cover at least one main surface of the control board, heat transfer by radiation from the heat diffusion portion to the control board can be suppressed, and the control unit can be protected from the heat of the accommodation portion.

[0016] According to a fourth aspect of the present invention (which fourth aspect is based on any one of the first aspect to the third aspect), the housing has a first housing for accommodating the control unit, the first housing is formed of a non-conductive material, and the control unit has a wireless communication unit for wireless communication with the outside.

[0017] According to the fourth aspect of the present invention, the wireless communication unit is accommodated in the first housing made of a non-conductive material, and the heat diffusion portion has a portion open in the circumferential direction of the accommodation portion on the wireless communication unit side. Thus, wireless communication with the outside can be ensured using the wireless communication unit.

[0018] According to a fifth aspect of the present invention (which fifth aspect is based on the fourth aspect), the heat diffusion portion is accommodated in the first housing, and the thermal conductivity of the heat diffusion portion is greater than the thermal conductivity of the first housing.

[0019] According to the fifth aspect of the present invention, by making the thermal conductivity of the heat diffusion portion greater than the thermal conductivity of the first housing, heat can be evenly diffused within the first housing, and local heating of the surface of the first housing can be prevented.

[0020] According to a sixth aspect of the present invention (which sixth aspect is based on the fourth aspect or the fifth aspect), the length of the first housing in the longitudinal direction on the side where the accommodation portion is arranged is less than the length of the first housing in the longitudinal direction on the side where the control unit is arranged.

[0021] According to the sixth aspect of the present invention, by making the length of the first housing in the longitudinal direction on the side where the accommodation portion is arranged less than the length of the first housing in the longitudinal direction on the side where the control unit is arranged, the heat of the accommodation portion can be efficiently diffused to the second housing arranged along the first housing.

[0022] According to a seventh aspect of the present invention (the seventh aspect being based on any one of the fourth to sixth aspects), the heat dissipation portion is arranged to be in contact with the inner surface of the first housing.

[0023] According to the seventh aspect of the present invention, by arranging the heat dissipation portion to be in contact with the inner surface of the first housing, the heat of the heat dissipation portion can be efficiently dissipated to the outside from the surface of the first housing after using the flavor inhaler.

[0024] According to an eighth aspect of the present invention (the eighth aspect being based on any one of the fourth to seventh aspects), the housing has a second housing that does not accommodate the wireless communication unit, and the thermal conductivity of the second housing is greater than that of the first housing.

[0025] According to the eighth aspect of the present invention, by making the thermal conductivity of the second housing greater than that of the first housing, it becomes easier to dissipate the heat of the first housing to the second housing, thereby suppressing the surface temperature of the first housing from becoming too high.

[0026] According to a ninth aspect of the present invention (the ninth aspect being based on the eighth aspect), the first housing is made of resin and the second housing is made of metal.

[0027] According to the ninth aspect of the present invention, by making the first housing made of resin and the second housing made of metal, it becomes easier to dissipate the heat of the first housing to the second housing, thereby preventing the surface temperature of the first housing from becoming too high.

[0028] According to a tenth aspect of the present invention (the tenth aspect being based on the eighth or ninth aspect), the contact surface between the first housing and the second housing is inclined with respect to a direction orthogonal to the longitudinal direction.

[0029] According to the tenth aspect of the present invention, by making the contact surface between the first housing and the second housing inclined with respect to a direction orthogonal to the longitudinal direction, the lengths of the first housing and the second housing in the longitudinal direction can be changed on the side where the accommodation portion is arranged and the side where the control unit is arranged.

[0030] According to an eleventh aspect of the present invention (the eleventh aspect being based on any one of the eighth to tenth aspects), the heat dissipation portion is arranged to be in contact with the second housing.

[0031] According to the eleventh aspect of the present invention, by arranging the heat dissipation portion to be in contact with the second housing, the heat of the heat dissipation portion can be dissipated to the second housing.

[0032] According to a twelfth aspect of the present invention (the twelfth aspect being based on any one of the first to eleventh aspects), the components of the control unit are arranged not to face the accommodation portion.

[0033] According to the twelfth aspect of the present invention, by arranging the components of the control unit so as not to face the accommodation part, the influence of the heat of the accommodation part on the components of the control unit can be reduced.

[0034] According to the thirteenth aspect of the present invention (the thirteenth aspect is based on any one of the first aspect to the twelfth aspect), the length of the heat diffusion part in the longitudinal direction increases from the side where the accommodation part is arranged towards the side where the control unit is arranged.

[0035] According to the thirteenth aspect of the present invention, by making the length of the heat diffusion part in the longitudinal direction increase from the side where the accommodation part is arranged towards the side where the control unit is arranged, the surface area of the heat diffusion part around the control unit becomes larger, thereby promoting heat diffusion and reducing the temperature of the heat diffusion part on the side where the control unit is arranged.

[0042] Figure 7 is an enlarged view of the heat diffusion sleeve taken from Figure 5 Detailed Description of the Embodiment

[0043] Embodiments of the present invention will be described below with reference to the accompanying drawings. In the following drawings, the same or corresponding components are denoted by the same reference numerals, and redundant descriptions are omitted.

[0044] Figure 1 is a perspective view of a flavor inhaler 100 according to an embodiment of the present invention. Figure 2 ​​​​​​​​It is a perspective view of a flavor inhaler 100 that accommodates a consumable material 120 inserted through an opening 110. For ease of description, an X-Y-Z orthogonal coordinate system can be applied to the drawings described in this specification. In this coordinate system, the Z-axis is oriented vertically upward, the X-Y plane is arranged to cut across the flavor inhaler 100 horizontally, and the Y-axis is arranged to extend from the front surface to the rear surface of the flavor inhaler 100. The Z-axis direction can also refer to the insertion direction of the consumable material 120 accommodated in a chamber 50 to be described later. Additionally, the X-axis direction can also refer to the longitudinal direction of the device in a plane orthogonal to the insertion direction of the consumable material 120. The Y-axis direction can also refer to the lateral direction of the device in a plane orthogonal to the insertion direction of the consumable material 120.

[0045] The flavor inhaler 100 is configured to generate a flavor-containing aerosol by, for example, heating a rod-shaped consumable material 120 that has a flavor source containing an aerosol source. As an example, the consumable material 120 includes a smokable substance that contains a flavor source (such as tobacco) and an aerosol source at the tip end in the negative Z-axis direction, and includes a filter on another part. Examples of aerosol sources that can be cited include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. It should be noted that in this embodiment, the consumable material 120 is described as rod-shaped, but the consumable material used in the flavor inhaler 100 is not limited to this shape. For example, the consumable material can also be configured to include a cartridge that houses a liquid aerosol source. Additionally, the cartridge can include a heating unit.

[0046] As Figure 1 and Figure 2 shown, the flavor inhaler 100 includes: a housing 102 formed by an upper housing (first housing) 104 and a lower housing (second housing) 106; and a slide cover 108.

[0047] The housing 102 forms the outermost housing of the flavor inhaler 100 and has a size suitable for the user's hand. When the user uses the flavor inhaler 100, the user can inhale the aerosol while holding the flavor inhaler 100 in their hand. It should be noted that in this case, for the housing 102, for example, the upper housing 104 is formed of a resin such as polycarbonate, and for example, the lower housing 106 is formed of a metal such as aluminum. However, the housing 102 is not limited to the above materials and can also be made of, for example, resin, and any suitable material can be selected, such as, in particular, polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene) resin, PEEK (polyetheretherketone), or a polymer alloy containing multiple types of polymers.

[0048] The upper housing 104 includes an opening 110 for receiving the consumable material 120, and a sliding cover 108 is slidably attached to the upper housing 104 to close the opening 110. Specifically, the sliding cover 108 is configured to be movable along the outer surface of the upper housing 104 between a closed position for closing the opening 110 of the upper housing 104 and an open position for opening the opening ( Figure 1 and Figure 2 the positions shown). For example, a user can manually operate the sliding cover 108 to move the sliding cover 108 between the closed position and the open position. Thus, the sliding cover 108 can allow or restrict the entry of the consumable material 120 into the interior of the flavor inhaler 100.

[0049] Figure 1 and Figure 2 The housing 102 of the flavor inhaler 100 is shown in such a manner that the mating surfaces of the upper housing 104 and the lower housing 106 intersect the X-Y plane obliquely, but the housing 102 is not limited to this configuration. For example, the housing 102 can also be formed of three or more members.

[0050] The flavor inhaler 100 can further include a terminal, which is not shown in the drawings. For example, the terminal can be an interface for connecting the flavor inhaler 100 to an external power source. When the power source of the flavor inhaler 100 is a rechargeable battery, the external power source can be connected to the terminal so that current is supplied from the external power source to the power source, and the power source can be charged. In addition, data related to the operation of the flavor inhaler 100 can also be sent to an external device by connecting a data transmission cable to the terminal.

[0051] Next, the internal structure of the flavor inhaler 100 according to an embodiment of the present invention will be described. Figure 3 is a cross-sectional view of the flavor inhaler along Figure 1 the arrow 3-3 in. As Figure 3 shown, a power supply unit 20, an atomization unit 30, and a control unit 80 are provided in the internal space of the housing 102 of the flavor inhaler 100.

[0052] The control unit 80 (wireless communication unit) includes a board (control board) 82. The board 82 can include, for example, a microprocessor, etc., and can control the power supply from the power supply unit 20 to the atomization unit 30. This enables the control unit 80 to control the heating of the consumable material 120 by the atomization unit 30. In addition, the control unit 80 includes a Bluetooth (registered trademark) interface (element) 28. The control unit 80 can communicate with an external device via the Bluetooth (registered trademark) interface 28.

[0053] The power supply unit 20 includes a power supply 21 that is electrically connected to the board 82 of the control unit 80. For example, the power supply 21 can be a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the atomization unit 30 via the board 82. This allows the power supply 21 to supply power to the atomization unit 30 to appropriately heat the consumable material 120.

[0054] The atomization unit 30 includes: a chamber (accommodating portion) 50 extending in the longitudinal direction of the consumable material 120; a heating unit (not depicted) surrounding a part of the chamber 50; a heat insulation portion 32; and a substantially cylindrical insertion guide member 34. The chamber 50 is configured to accommodate the consumable material 120. The heating unit is configured to contact the outer circumferential surface of the chamber 50 and heat the consumable material 120 accommodated in the chamber 50. As an example, a sensor can be provided inside or near the consumable material 120, and the heating unit can also include an induction coil for inductively heating the sensor.

[0055] The heat insulation portion 32 is configured to surround the chamber 50 and the heating unit. For example, the heat insulation portion 32 can be aerogel. The insertion guide member 34 is formed of a resin material such as PEEK, PC, or ABS, for example, and is provided between the sliding cover 108 (closed position) and the chamber 50. The insertion guide member 34 communicates with the outside of the flavor inhaler 100 when the sliding cover 108 is in the open position, and guides the consumable material 120 into the chamber 50 when the consumable material 120 is inserted into the insertion guide member 34.

[0056] In addition, the atomization unit 30 and the control unit 80 are covered by a heat diffusion sleeve (heat diffusion portion) 70 and arranged in the internal space of the housing 102. The heat diffusion sleeve 70 is made of a material with high thermal conductivity (such as metal) and diffuses the heat generated by the atomization unit 30 into the interior of the housing 102. The heat diffusion sleeve 70 can be configured to be placed only inside the upper housing 104 without interfering with the lower housing 106. Moreover, an open area can also be provided in the heat diffusion sleeve 70 so as not to interfere with the communication with an external device through the Bluetooth (registered trademark) interface 28 of the control unit 80. Although metal members generally interfere with electromagnetic waves, the control unit 80 can communicate with an external device via the Bluetooth (registered trademark) interface 28, at least through the open area of the heat diffusion sleeve 70.

[0057] Next, the characteristic structure of the flavor inhaler 100 according to an embodiment of the present invention will be described. Figure 4 is a front view of a flavor inhaler according to an embodiment of the present invention. The cylindrical chamber 50 is shown by Figure 4 the imaginary line in, which is accommodated in the housing 102 and accommodates the consumable material 120 to heat the consumable material 120.

[0058] As shown inFigure 4 As shown, the upper housing 104 and the lower housing 106 are arranged along the longitudinal direction of the flavor inhaler 100. The chamber 50 includes a first accommodation portion 51 accommodated in the upper housing 104 and a second accommodation portion 52 accommodated in the lower housing 106.

[0059] The upper housing 104 is made of a non-conductive material, such as polycarbonate (PC), ABS (acrylonitrile-butadiene-styrene) resin, PEEK (polyetheretherketone), or a polymer alloy containing various types of polymers, as described above. The lower housing 106 is made of metal (such as aluminum), as described above.

[0060] Figure 5 is a perspective view of the flavor inhaler 100 with the upper housing 104 removed. Figure 6 is Figure 5 a plan view of the flavor inhaler 100 shown. As Figure 5 and Figure 6 shown, the chamber 50 and the control unit 80 that controls the operation of the flavor inhaler 100 are arranged adjacent to each other in a direction orthogonal to the longitudinal direction of the flavor inhaler 100.

[0061] The heat diffusion sleeve 70 is arranged to cover at least a part of the first accommodation portion 51 that constitutes the chamber 50 and to diffuse the heat in the chamber 50. Here, the heat diffusion sleeve 70 and the control unit 80 are accommodated in the upper housing 104. As described above, the control unit 80 can perform wireless communication with an external device via the Bluetooth (registered trademark) interface 28.

[0062] Figure 7 is taken from Figure 5 of the heat diffusion sleeve 70. As Figure 7 shown, the heat diffusion sleeve 70 includes: a main body portion 71, an extension portion 72 that extends from the main body portion 71 toward the control unit 80 and extends beyond the chamber 50, and a contact portion 73 that contacts the lower housing 106 when assembled. The heat diffusion sleeve 70 also includes an opening portion 74 that is at least partially open on the control unit 80 side along the circumferential direction of the chamber 50.

[0063] In this way, the control unit 80 that serves as a wireless communication unit for performing wireless communication with the outside is accommodated in the upper housing 104 made of a non-conductive material, and the heat diffusion sleeve 70 that covers the chamber 50 is partially open along the circumferential direction of the chamber 50. Therefore, the heat in the chamber 50 can be diffused by means of the heat diffusion sleeve 70 while protecting the wireless communication with the outside through the control unit 80.

[0064] In addition, the heat diffusion sleeve 70 covering the chamber 50 is partially open on the control unit 80 side in the circumferential direction of the chamber 50. Therefore, the heat of the chamber 50 can be diffused by means of the heat diffusion sleeve 70 while protecting the control unit 80 from the heat of the chamber 50. In addition, the wireless communication with the outside can be protected by the control unit 80 while also suppressing the diffusion of the heat of the chamber 50 to the control unit 80.

[0065] As Figures 5 to 7 shown, the heat diffusion sleeve 70 is preferably configured to extend beyond the chamber 50 towards the control unit 80. By configuring the heat diffusion sleeve 70 to extend beyond the chamber 50 towards the control unit 80, the heat diffusion in the radial direction of the chamber 50 can be promoted.

[0066] In addition, as Figure 5 and Figure 6 shown, the heat diffusion sleeve 70 is preferably arranged not to cover at least one main surface of the plate 82. That is, the extending portion 72 of the heat diffusion sleeve 70 is preferably arranged not to cover the surface of the element on which the plate 82 is arranged. By arranging the heat diffusion sleeve 70 not to cover at least one main surface of the plate 82, the heat transfer by radiation from the heat diffusion sleeve 70 to the plate 82 can be suppressed, and the control unit 80 can be protected from the heat of the chamber 50.

[0067] In addition, the thermal conductivity of the heat diffusion sleeve 70 is preferably greater than the thermal conductivity of the upper housing 104. By making the thermal conductivity of the heat diffusion sleeve 70 greater than the thermal conductivity of the upper housing 104, the heat can be evenly diffused within the upper housing 104, and the local high temperature on the surface of the upper housing 104 can be suppressed.

[0068] In addition, the thermal conductivity of the lower housing 106 is preferably greater than the thermal conductivity of the upper housing 104. By making the thermal conductivity of the lower housing 106 greater than the thermal conductivity of the upper housing 104, the heat of the upper housing 104 is more easily diffused to the lower housing 106, and thus the local high temperature on the surface of the upper housing 104 can be suppressed.

[0069] In addition, the upper housing 104 is preferably made of resin, and the lower housing 106 is preferably made of metal. By making the upper housing 104 made of resin and the lower housing 106 made of metal, the heat of the upper housing 104 is more easily diffused to the lower housing 106, and thus the local high temperature on the surface of the upper housing 104 can be suppressed.

[0070] In addition, as Figure 4As shown, the contact surface between the upper housing 104 and the lower housing 106 is preferably inclined with respect to a direction orthogonal to the longitudinal direction. By inclining the contact surface between the upper housing 104 and the lower housing 106 with respect to a direction orthogonal to the longitudinal direction, the lengths of the upper housing 104 and the lower housing 106 in the longitudinal direction can be changed on the side where the chamber 50 is arranged and on the side where the chamber 50 is not arranged.

[0071] In addition, as Figure 4 shown, the length of the upper housing 104 in the longitudinal direction on the side where the chamber 50 is arranged is smaller than the length of the upper housing 104 in the longitudinal direction on the side where the chamber 50 is not arranged. By making the length of the upper housing 104 in the longitudinal direction on the side where the chamber 50 is arranged smaller than the length of the upper housing 104 in the longitudinal direction on the side where the chamber 50 is not arranged, the heat of the chamber 50 can be efficiently diffused to the lower housing 106.

[0072] In addition, the heat diffusion sleeve 70 is preferably arranged in contact with the inner surface of the upper housing 104. By arranging the heat diffusion sleeve 70 in contact with the inner surface of the upper housing 104, the heat of the heat diffusion sleeve 70 can be efficiently diffused from the surface of the upper housing 104 to the outside after using the flavor inhaler 100.

[0073] In addition, as Figure 7 shown, the heat diffusion sleeve 70 is preferably arranged in contact with the lower housing 106. That is, the heat diffusion sleeve 70 is preferably arranged to be in contact with the lower housing 106 through, for example, the contact portion 73. By arranging the heat diffusion sleeve 70 in contact with the lower housing 106, the heat of the heat diffusion sleeve 70 can be diffused to the lower housing 106.

[0074] In addition, as Figure 5 and Figure 6 shown, the components of the control unit 80 (for example, the Bluetooth (registered trademark) interface 28) are preferably arranged not to face the chamber 50. By arranging the components of the control unit 80 not to face the chamber 50, the influence of the heat of the chamber 50 on the components of the control unit 80 can be reduced.

[0075] In addition, as Figure 5 and Figure 7 shown, the length of the heat diffusion sleeve 70 in the longitudinal direction preferably increases from the side where the chamber 50 is arranged toward the side where the chamber 50 is not arranged (that is, from the side where the chamber 50 is arranged toward the side where the control unit 80 is arranged). By making the length of the heat diffusion sleeve 70 in the longitudinal direction increase from the side where the chamber 50 is arranged toward the side where the chamber 50 is not arranged, the surface area of the heat diffusion sleeve 70 around the control unit 80 can be increased, thereby promoting heat diffusion and reducing the temperature of the heat diffusion sleeve 70 on the side where the control unit 80 is arranged.

[0076] It should be noted that the surface of the heat diffusion sleeve 70 does not need to be flat, and the thickness of the heat diffusion sleeve 70 does not need to be uniform. For example, instead of changing the length of the heat diffusion sleeve 70 in the longitudinal direction on the side where the chamber 50 is arranged and the side where the control unit 80 is arranged, the surface of the heat diffusion sleeve 70 having a undulating shape or the like can also be formed on the side where the control unit 80 is arranged. By forming the surface of the heat diffusion sleeve 70 having a undulating shape on the side where the control unit 80 is arranged, the surface area of the heat diffusion sleeve 70 around the control unit 80 can be increased, thereby promoting heat diffusion and reducing the temperature of the heat diffusion sleeve 70 on the side where the control unit 80 is arranged.

[0077] The embodiments of the present invention have been described above, but the embodiments of the present invention described above are for facilitating the understanding of the present invention and do not limit the present invention. The present invention can be modified and improved without departing from its spirit, and its equivalents are included in the present invention. In addition, within the scope where at least some of the above problems can be solved or at least some of the effects can be achieved, the combination or omission of the components described in the claims and the specification is possible.
