flavor aspirator

[0001] The present invention relates to a flavor inhaler.

[0002] Conventionally, flavor inhalers for inhaling flavors and the like without burning the material are known, including a flavor inhaler that includes a metallic heat diffusion unit that diffuses heat from a storage unit in which a consumable material is stored and heated to the surrounding area to prevent hot spots from occurring during use (see, for example, Patent Document 1).

[0003] International Publication No. 2020 / 199210

[0004] In the flavor inhaler disclosed in Patent Document 1, if the control unit that controls the operation of the flavor inhaler is placed adjacent to the storage unit, the heat from the storage unit diffused by the thermal diffusion unit may have an undesirable effect on the control unit.

[0005] The present invention has been made to solve at least some of the above-mentioned problems, and aims to protect the control unit from the heat of the storage unit while diffusing the heat of the storage unit using a thermal diffusion unit.

[0006] A first aspect of the present invention provides a flavor inhaler comprising: a cylindrical container that contains a consumable product for heating; a thermal diffusion unit that is arranged to cover at least a portion of the container and diffuses heat from the container; a control unit that controls the operation of the flavor inhaler; and a housing that contains the container, the thermal diffusion unit, and the control unit, wherein the container and the control unit are arranged adjacent to each other in a direction perpendicular to the longitudinal direction of the flavor inhaler, and the thermal diffusion unit has a portion open circumferentially toward the control unit.

[0007] According to the first aspect of the present invention, the thermal diffusion unit covering the housing unit is open at a portion on the control unit side in the circumferential direction of the housing unit, thereby protecting the control unit from the heat of the housing unit and allowing the thermal diffusion unit to diffuse the heat of the housing unit.

[0008] In a second aspect of the present invention, the thermal diffusion portion in the first aspect is configured to extend beyond the accommodation portion toward the control portion.

[0009] According to the second aspect of the present invention, by configuring the thermal diffusion unit to extend beyond the housing unit toward the control unit, it is possible to promote thermal diffusion in the radial direction of the housing unit.

[0010] In a third aspect of the present invention, in the first or second aspect, the control unit has a control board, and the thermal diffusion unit is arranged so as not to cover at least one main surface of the control board.

[0011] According to the third aspect of the present invention, by positioning the thermal diffusion unit so as not to cover at least one main surface of the control board, heat transfer by radiation from the thermal diffusion unit to the control board can be suppressed, and the control unit can be better protected from the heat of the accommodating unit.

[0012] In a fourth aspect of the present invention, in any of the first to third aspects, the housing has a first housing that accommodates a control unit, the first housing is made of a non-conductive material, and the control unit has a wireless communication unit that communicates wirelessly with the outside.

[0013] According to a fourth aspect of the present invention, the wireless communication unit is accommodated in the first housing made of a non-conductive material, and the thermal diffusion unit has a portion open on the wireless communication unit side in the circumferential direction of the accommodating unit, thereby ensuring wireless communication with the outside via the wireless communication unit.

[0014] In a fifth aspect of the present invention, in the fourth aspect, the thermal diffusion unit is accommodated in the first housing, and the thermal conductivity of the thermal diffusion unit is greater than the thermal conductivity of the first housing.

[0015] According to the fifth aspect of the present invention, by making the thermal conductivity of the thermal diffusion portion greater than the thermal conductivity of the first housing, heat is diffused evenly within the first housing, and the surface of the first housing can be prevented from becoming locally hot.

[0016] In a sixth aspect of the present invention, in the fourth or fifth aspect, the longitudinal length of the first housing is shorter on the side where the accommodating portion is arranged than on the side where the control portion is arranged.

[0017] According to the sixth aspect of the present invention, by making the longitudinal length of the first housing on the side where the storage unit is located shorter than the longitudinal length of the first housing on the side where the control unit is located, the heat of the storage unit can be efficiently diffused to the second housing arranged along the first housing.

[0018] In a seventh aspect of the present invention, in any one of the fourth to sixth aspects, the thermal diffusion part is arranged in contact with the inner surface of the first housing.

[0019] According to the seventh aspect of the present invention, by arranging the thermal diffusion unit in contact with the inner surface of the first housing, the heat of the thermal diffusion unit can be efficiently diffused from the surface of the first housing to the outside after use of the flavor inhaler.

[0020] In an eighth aspect of the present invention, in any of the fourth to seventh aspects, the housing has a second housing that does not house a wireless communication unit, and the thermal conductivity of the second housing is greater than the thermal conductivity of the first housing.

[0021] 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 diffuse heat from the first housing to the second housing, thereby preventing the surface of the first housing from becoming too hot.

[0022] In a ninth aspect of the present invention, in the eighth aspect, the first housing is made of resin and the second housing is made of metal.

[0023] According to the ninth aspect of the present invention, by making the first housing out of resin and the second housing out of metal, it becomes easier to diffuse heat from the first housing to the second housing, thereby preventing the surface of the first housing from becoming too hot.

[0024] A tenth aspect of the present invention is the eighth or ninth aspect, wherein the contact surface between the first housing and the second housing is inclined with respect to a direction perpendicular to the longitudinal direction.

[0025] According to the tenth aspect of the present invention, by tilting the contact surface between the first housing and the second housing in a direction perpendicular to the longitudinal direction, the longitudinal lengths of the first housing and the second housing can be changed between the side where the storage section is located and the side where the control section is located.

[0026] In an eleventh aspect of the present invention, in any one of the eighth to tenth aspects, the thermal diffusion part is arranged in contact with the second housing.

[0027] According to the eleventh aspect of the present invention, by arranging the thermal diffusion unit in contact with the second housing, it is possible to diffuse heat from the thermal diffusion unit into the second housing.

[0028] In a twelfth aspect of the present invention, in any one of the first to eleventh aspects, the elements of the control section are arranged so as not to face the accommodation section.

[0029] According to the twelfth aspect of the present invention, the elements of the control unit are arranged so as not to face the accommodation unit, thereby making it possible to reduce the influence of heat from the accommodation unit on the elements of the control unit.

[0030] In a thirteenth aspect of the present invention, in any one of the first to twelfth aspects, the longitudinal length of the thermal diffusion unit increases from the side where the accommodation unit is located to the side where the control unit is located.

[0031] According to the thirteenth aspect of the present invention, by increasing the longitudinal length of the thermal diffusion unit from the side where the storage unit is located toward the side where the control unit is located, the surface area of ​​the thermal diffusion unit around the control unit is increased, promoting thermal diffusion and reducing the temperature of the thermal diffusion unit on the side where the control unit is located.

[0033] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings described below, identical or corresponding components are designated by the same reference numerals, and redundant description will be omitted.

[0034] FIG. 1 is a perspective view of a flavor inhaler 100 according to one embodiment of the present invention. FIG. 2 is a perspective view of the flavor inhaler 100 containing a consumable product 120 inserted through an opening 110. For ease of explanation, the drawings described in this specification may be accompanied by an X-Y-Z Cartesian coordinate system. In this coordinate system, the Z axis faces vertically upward, the X-Y plane is positioned to cut the flavor inhaler 100 horizontally, and the Y axis is positioned to extend from the front to the back of the flavor inhaler 100. The Z axis can also be referred to as the insertion direction of the consumable product 120 contained in a chamber 50 (described below). The X axis can also be referred to as the longitudinal direction of the device in a plane perpendicular to the insertion direction of the consumable product 120. The Y axis can also be referred to as the lateral direction of the device in a plane perpendicular to the insertion direction of the consumable product 120.

[0035] The flavor inhaler 100 is configured to generate a flavor-containing aerosol by heating, for example, a stick-shaped consumable product 120 having a flavor source containing an aerosol source. As an example, the consumable product 120 is configured to include a smokable article containing a flavor source, such as tobacco, and an aerosol source at its tip in the negative Z-axis direction, and a filter at another location. Examples of aerosol sources include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. While the present embodiment describes the consumable product 120 as being stick-shaped, the consumable product used in the flavor inhaler 100 is not limited to this. For example, the consumable product may be configured to include a cartridge containing a liquid aerosol source. Furthermore, the cartridge may have a heating unit.

[0036] As shown in FIGS. 1 and 2, the flavor inhaler 100 has a housing 102 composed of an upper housing (first housing) 104 and a lower housing (second housing) 106, and a slide cover 108.

[0037] The housing 102 constitutes the outermost housing of the flavor inhaler 100 and is sized to fit in a user's hand. When using the flavor inhaler 100, the user can hold the flavor inhaler 100 in their hand and inhale the aerosol. Regarding the housing 102, the upper housing 104 is formed from a resin such as polycarbonate, and the lower housing 106 is formed from a metal such as aluminum. However, the material of the housing 102 is not limited to these and can be any suitable resin, particularly polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (Polyether Ether Ketone), or a polymer alloy containing multiple types of polymers.

[0038] The upper housing 104 has an opening 110 for receiving the consumable product 120, and the slide cover 108 is slidably attached to the upper housing 104 to close the opening 110. Specifically, the slide cover 108 is configured to be movable along the outer surface of the upper housing 104 between a closed position, at which the opening 110 of the upper housing 104 is closed, and an open position (the position shown in FIGS. 1 and 2 ), at which the opening is open. For example, a user can manually operate the slide cover 108 to move the slide cover 108 between the closed position and the open position. In this way, the slide cover 108 can allow or restrict access of the consumable product 120 to the inside of the flavor inhaler 100.

[0039] 1 and 2 show the housing 102 of the flavor inhaler 100 such that the joint surface between the upper housing 104 and the lower housing 106 intersects obliquely with the XY plane, but the configuration of the housing 102 is not limited to this. For example, the housing 102 may be configured from three or more members.

[0040] The flavor inhaler 100 may further have a terminal (not shown). The terminal may be an interface for connecting the flavor inhaler 100 to, for example, an external power source. If the power source of the flavor inhaler 100 is a rechargeable battery, connecting the external power source to the terminal allows current to flow from the external power source to the power source, thereby charging the power source. In addition, connecting a data transmission cable to the terminal may allow data related to the operation of the flavor inhaler 100 to be transmitted to an external device.

[0041] Next, the internal structure of the flavor inhaler 100 according to one embodiment of the present invention will be described. Figure 3 is a cross-sectional view of the flavor inhaler 100 taken along the arrow 3-3 shown in Figure 1. As shown in Figure 3, 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.

[0042] The control unit 80 (wireless communication unit) includes a board (control board) 82. The board 82 includes, for example, a microprocessor and is capable of controlling the supply of power from the power supply unit 20 to the atomization unit 30. This allows the control unit 80 to control the heating of the consumable product 120 by the atomization unit 30. The control unit 80 also includes a Bluetooth (registered trademark) interface (element) 28. The control unit 80 is capable of communicating with external devices via the Bluetooth (registered trademark) interface 28.

[0043] The power supply unit 20 has a power source 21 electrically connected to a circuit board 82 of the control unit 80. The power source 21 may be, for example, a rechargeable battery or a non-rechargeable battery. The power source 21 is electrically connected to the atomizing unit 30 via the circuit board 82. This allows the power source 21 to supply power to the atomizing unit 30 so as to appropriately heat the consumable product 120.

[0044] The atomization unit 30 has a chamber (storage unit) 50 extending in the longitudinal direction of the consumable product 120, a heating unit (not shown) that surrounds a portion of the chamber 50, a heat insulating unit 32, and a generally cylindrical insertion guide member 34. The chamber 50 is configured to store the consumable product 120. The heating unit is configured to contact the outer peripheral surface of the chamber 50 and heat the consumable product 120 stored in the chamber 50. As an example, a susceptor may be provided inside or adjacent to the consumable product 120, and the heating unit may include an induction coil for inductively heating the susceptor.

[0045] The heat insulating section 32 is disposed to surround the chamber 50 and the heating section. The heat insulating section 32 may be made of, for example, aerogel. The insertion guide member 34 is formed of a resin material such as PEEK, PC, or ABS, and is provided between the slide cover 108 in the closed position and the chamber 50. When the slide cover 108 is in the open position, the insertion guide member 34 communicates with the outside of the flavor inhaler 100, and guides the insertion of the consumable product 120 into the chamber 50 by inserting the consumable product 120 into the insertion guide member 34.

[0046] Furthermore, the nebulizer 30 and the control unit 80 are covered by a heat diffusion sleeve (heat diffusion unit) 70 and disposed within the interior space of the housing 102. The heat diffusion sleeve 70 is made of a material with high thermal conductivity, such as metal, and dissipates heat generated by the nebulizer 30 within the housing 102. The heat diffusion sleeve 70 may be configured to be disposed only within the upper housing 104 without interfering with the lower housing 106. Furthermore, an open area may be provided in the heat diffusion sleeve 70 to prevent interference with communication with external devices via the Bluetooth® interface 28 of the control unit 80. While metal members generally interfere with electromagnetic waves, the open area of ​​the heat diffusion sleeve 70 at least serves as a path through which the control unit 80 can communicate with external devices via the Bluetooth® interface 28.

[0047] Next, a description will be given of the characteristic structure of the flavor inhaler 100 according to one embodiment of the present invention. Fig. 4 is a front view of the flavor inhaler 100 according to one embodiment of the present invention. In Fig. 4, a cylindrical chamber 50 that is housed in the housing 102 and that houses the consumable product 120 for heating is shown by imaginary lines.

[0048] 4, the upper housing 104 and the lower housing 106 are arranged along the longitudinal direction of the flavor inhaler 100. The chamber 50 has a first housing portion 51 housed in the upper housing 104 and a second housing portion 52 housed in the lower housing 106.

[0049] As described above, the upper housing 104 is made of a non-conductive material such as polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (Polyether Ether Ketone), or a polymer alloy containing multiple types of polymers. As described above, the lower housing 106 is made of a metal such as aluminum.

[0050] Fig. 5 is a perspective view of the flavor inhaler 100 with the upper housing 104 removed. Fig. 6 is a plan view of the flavor inhaler 100 shown in Fig. 5. As shown in Figs. 5 and 6, the chamber 50 and the control unit 80 that controls the operation of the flavor inhaler 100 are disposed adjacent to each other in a direction perpendicular to the longitudinal direction of the flavor inhaler 100.

[0051] The heat diffusion sleeve 70 is disposed so as to cover the first housing portion 51, which is at least a part of the chamber 50, and diffuses heat from the chamber 50. The heat diffusion sleeve 70 and the control unit 80 are housed in the upper housing 104. As described above, the control unit 80 may perform wireless communication with the outside via the Bluetooth (registered trademark) interface 28.

[0052] Fig. 7 is an enlarged view of the heat diffusion sleeve 70 shown in Fig. 5. As shown in Fig. 7, the heat diffusion sleeve 70 has a main body portion 71, an extension portion 72 that extends from the main body portion 71 toward the control unit 80 beyond the chamber 50, and a contact portion 73 that comes into contact with the lower housing 106 when assembled. The heat diffusion sleeve 70 also has an open portion 74 that is partially open on the control unit 80 side in the circumferential direction of the chamber 50.

[0053] In this way, the control unit 80, which functions as a wireless communication unit that communicates wirelessly with the outside, is housed 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 in the circumferential direction of the chamber 50. Therefore, the heat of the chamber 50 can be diffused by the heat diffusion sleeve 70 while ensuring wireless communication with the outside by the control unit 80.

[0054] Furthermore, 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 diffusion sleeve 70 can diffuse the heat of the chamber 50 while protecting the control unit 80 from the heat of the chamber 50. Furthermore, it is possible to prevent the heat of the chamber 50 from diffusing to the control unit 80 and to ensure wireless communication between the control unit 80 and the outside.

[0055] 5 to 7, the heat diffusion sleeve 70 is preferably configured to extend beyond the chamber 50 toward the control unit 80. By configuring the heat diffusion sleeve 70 to extend beyond the chamber 50 toward the control unit 80, heat diffusion in the radial direction of the chamber 50 can be promoted.

[0056] 5 and 6 , the heat diffusion sleeve 70 is preferably positioned so as not to cover at least one main surface of the substrate 82. That is, the extension 72 of the heat diffusion sleeve 70 is preferably positioned so as not to cover the surface of the substrate 82 on which elements are arranged. By positioning the heat diffusion sleeve 70 so as not to cover at least one main surface of the substrate 82, heat transfer by radiation from the heat diffusion sleeve 70 to the substrate 82 can be suppressed, and the control unit 80 can be better protected from the heat of the chamber 50.

[0057] Furthermore, the thermal conductivity of the heat diffusion sleeve 70 is preferably greater than that of the upper housing 104. By making the thermal conductivity of the heat diffusion sleeve 70 greater than that of the upper housing 104, heat is diffused evenly within the upper housing 104, and it is possible to prevent the surface of the upper housing 104 from becoming locally hot.

[0058] Furthermore, it is preferable that the thermal conductivity of the lower housing 106 be greater than that of the upper housing 104. By making the thermal conductivity of the lower housing 106 greater than that of the upper housing 104, heat from the upper housing 104 can be more easily diffused to the lower housing 106, thereby preventing the surface of the upper housing 104 from becoming too hot.

[0059] Preferably, the upper housing 104 is made of resin and the lower housing 106 is made of metal. By making the upper housing 104 out of resin and the lower housing 106 out of metal, heat from the upper housing 104 can be more easily diffused to the lower housing 106, thereby preventing the surface of the upper housing 104 from becoming too hot.

[0060] 4, the contact surface between the upper housing 104 and the lower housing 106 is preferably inclined with respect to a direction perpendicular to the longitudinal direction. By inclining the contact surface between the upper housing 104 and the lower housing 106 with respect to a direction perpendicular to the longitudinal direction, the longitudinal lengths of the upper housing 104 and the lower housing 106 can be changed between the side where the chamber 50 is located and the side where the chamber 50 is not located.

[0061] 4, the longitudinal length of the upper housing 104 is preferably shorter on the side where the chamber 50 is disposed than on the side where the chamber 50 is not disposed. By making the longitudinal length of the upper housing 104 on the side where the chamber 50 is disposed shorter than the longitudinal length of the upper housing 104 on the side where the chamber 50 is not disposed, heat from the chamber 50 can be efficiently diffused to the lower housing 106.

[0062] Furthermore, the heat diffusion sleeve 70 is preferably disposed in contact with the inner surface of the upper housing 104. By disposing the heat diffusion sleeve 70 in contact with the inner surface of the upper housing 104, heat from the heat diffusion sleeve 70 can be efficiently diffused from the surface of the upper housing 104 to the outside after the flavor inhaler 100 is used.

[0063] 7, the heat spreading sleeve 70 is preferably disposed in contact with the lower housing 106. That is, the heat spreading sleeve 70 is preferably disposed in contact with the lower housing 106, for example, via a contact portion 73. By disposing the heat spreading sleeve 70 in contact with the lower housing 106, heat from the heat spreading sleeve 70 can be dispersed to the lower housing 106.

[0064] 5 and 6, it is preferable that the elements of the control unit 80, such as the Bluetooth (registered trademark) interface 28, are arranged so as not to face the chamber 50. By arranging the elements of the control unit 80 so as not to face the chamber 50, the effect of heat from the chamber 50 on the elements of the control unit 80 can be reduced.

[0065] 5 and 7, the longitudinal length of the thermal diffusion sleeve 70 preferably increases from the side where the chamber 50 is located to the side where the chamber 50 is not located, i.e., from the side where the chamber 50 is located to the side where the control unit 80 is located. By increasing the longitudinal length of the thermal diffusion sleeve 70 from the side where the chamber 50 is located to the side where the control unit 80 is located, the surface area of ​​the thermal diffusion sleeve 70 around the control unit 80 increases, promoting heat diffusion and reducing the temperature of the thermal diffusion sleeve 70 on the side where the control unit 80 is located.

[0066] The surface of the thermal diffusion sleeve 70 does not need to be flat, and the thickness of the thermal diffusion sleeve 70 does not need to be uniform. For example, instead of changing the longitudinal length of the thermal diffusion sleeve 70 between the side where the chamber 50 is located and the side where the control unit 80 is located, the surface of the thermal diffusion sleeve 70 on the side where the control unit 80 is located may be made uneven. By making the surface of the thermal diffusion sleeve 70 on the side where the control unit 80 is located uneven, the surface area of ​​the thermal diffusion sleeve 70 around the control unit 80 is increased, promoting heat diffusion and reducing the temperature of the thermal diffusion sleeve 70 on the side where the control unit 80 is located.

[0067] Although the embodiments of the present invention have been described above, the above-described embodiments of the invention are intended to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof. Furthermore, the components described in the claims and specification may be combined or omitted to the extent that at least part of the above-described problems can be solved or at least part of the effects can be achieved.
