Description

flavor aspirator

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

[0002] Conventionally, flavor inhalers for inhaling flavors and the like without burning a material have been known. The flavor inhalers have, for example, a chamber for accommodating a flavor-generating article and a heater for heating the flavor-generating article accommodated in the chamber (see, for example, Patent Document 1).

[0003] International Publication No. 2020 / 035454

[0004] In conventional flavor inhalers, the housing that houses the heater and the control unit may be composed of multiple parts. In such cases, it is preferable to prevent liquid from entering the housing through gaps between the parts as much as possible.

[0005] One object of the present invention is to prevent liquid from penetrating into the interior of a flavor inhaler having a housing made up of multiple parts through gaps between the parts.

[0006] According to a first aspect, there is provided a flavor inhaler. The flavor inhaler has a housing having a lower end and an upper end opposite the lower end and closer to the mouthpiece than the lower end. The housing includes a first housing and a second housing closer to the lower end than the first housing. The first housing has a first wall extending between the upper end and the lower end. The first wall has a first outer surface and a first inner surface. In a cross section perpendicular to the first outer surface and extending between the upper end and the lower end, a first end on the lower end side of the first outer surface is located closer to the lower end than a second end on the lower end side of the first inner surface. The first housing has a first end surface connecting the first end and the second end.

[0007] According to the first aspect, the first outer surface of the first housing near the mouthpiece extends further downward than the first inner surface, so that when the flavor inhaler is held, liquids such as rain flowing from above can be prevented from entering through the gap between the first housing and the second housing.

[0008] In the cross section, the first end may extend 0.3 mm or more toward the lower end than the second end.

[0009] In this case, the first end extends downward by a sufficient distance beyond the second end, so that when the flavor inhaler is held, liquids such as rain flowing from above are further prevented from entering through the gap between the first housing and the second housing.

[0010] The first end surface may be flat, and an angle formed between the first outer surface and the first end surface may be equal to or greater than 30° and equal to or less than 75°.

[0011] If the angle is less than 30°, the lower end of the first wall may become too thin, resulting in insufficient strength of the lower end of the first wall. If the angle is more than 75°, the difference in vertical position between the first end and the second end may become small, resulting in insufficient prevention of liquid from entering the housing. Therefore, if the angle is within the above numerical range, it is possible to prevent liquid from entering the housing while preventing a decrease in the strength of the lower end of the first wall.

[0012] The second housing has a second wall extending between the upper end and the lower end, the second wall having a second outer surface and a second inner surface, and being perpendicular to the second outer surface, and in a cross section extending between the upper end and the lower end, a third end on the upper end side of the second outer surface is located closer to the lower end than a fourth end on the upper end side of the second inner surface, and the second housing has a second end surface connecting the third end and the fourth end, and the first end surface and the second end surface may be arranged opposite each other.

[0013] In this case, the shape of the second wall of the second housing can be formed to correspond to the shape of the first wall of the first housing, thereby further preventing liquid from seeping in through the gap between the first and second housings.

[0014] A gap between the first end surface and the second end surface may be 0.1 mm or more and 0.5 mm or less.

[0015] If the gap is less than 0.1 mm, the gap between the first end face and the second end face will be too small, and depending on the manufacturing tolerances of the housing, the first end face and the second end face may come into contact, making it difficult to properly assemble the first and second housings. Furthermore, if the gap is more than 0.5 mm, the gap between the first end face and the second end face will be too large, making it difficult to adequately prevent liquid from entering the housing. Therefore, if the gap is within the above numerical range, it is possible to prevent liquid from entering the housing while also preventing housing assembly defects.

[0016] The second end surface may be flat, and an angle formed between the second outer surface and the second end surface may be equal to or greater than 105° and equal to or less than 150°.

[0017] If the angle is less than 105°, the difference in the vertical positions of the third end and the fourth end will be small, and there is a risk that the intrusion of liquid into the housing will not be sufficiently suppressed. If the angle is more than 150°, the upper end of the second wall will be too thin, and the strength of the upper end of the second wall will be insufficient. Therefore, if the angle is within the above numerical range, it is possible to suppress the intrusion of liquid into the housing while suppressing a decrease in the strength of the upper end of the second wall.

[0018] The device may include a heating assembly housed in the housing and configured to heat a consumable item, and a battery housed in the housing and configured to power the heating assembly.

[0019] In this case, when the flavor inhaler is held, liquids such as rain flowing from above are prevented from entering through the gap between the first housing and the second housing, thereby preventing failure of the heating assembly and battery housed in the housing.

[0020] The housing may have an opening into which a consumable item can be inserted, and the cross section may be parallel to a direction in which the consumable item is inserted.

[0021] The direction parallel to the insertion direction of the consumable product is usually oriented substantially vertically when the user uses (smokes) the flavor inhaler. Therefore, since the first end is located closer to the lower end than the second end in the direction parallel to the insertion direction of the consumable product, it is possible to further prevent liquids such as rain flowing from above from entering through the gap between the first and second housings when the flavor inhaler is held.

[0022] The upper end may be located on the first housing, and the lower end may be located on the second housing.

[0023] In this case, the housing can be composed of only the first housing and the second housing.

[0024] The first end surface may extend around the entire periphery of the first housing.

[0025] In this case, the first outer surface extends further downward than the first inner surface around the entire circumference of the first housing, which further prevents liquids such as rain flowing from above from entering through the gap between the first housing and the second housing when the flavor inhaler is held.

[0027] 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.

[0028] 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 item 120 inserted through an opening 110. For ease of explanation, the drawings described herein may include 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 item 120 contained in the 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 item 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 item 120.

[0029] The flavor inhaler 100 is configured to generate a flavor-containing aerosol by heating a stick-shaped consumable product 120 having a flavor source containing an aerosol source. For example, the consumable product 120 may be a cigarette with a smokable article including 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 consumable product 120 is described as being stick-shaped in this embodiment, the consumable product 120 used in the flavor inhaler 100 is not limited to this. For example, the consumable product may be configured to include a tank containing a liquid aerosol source. The consumable product may also have a heating unit. The flavor inhaler 100 may be configured to use both the stick-shaped consumable product 120 and a consumable product containing a liquid aerosol source.

[0030] As shown in FIGS. 1 and 2 , the flavor inhaler 100 has a housing 102 having a lower end b1 and an upper end t1. The upper end t1 is closer to the mouthpiece than the lower end b1 and is located opposite the lower end b1. In the example shown in FIG. 2 , the mouthpiece is provided on the consumable 120, but this is not limiting; the mouthpiece may also be provided on the flavor inhaler 100. The housing 102 has a first housing 104 and a second housing 106 that is closer to the lower end b1 than the first housing 104. In the illustrated example, the flavor inhaler 100 has a sliding cover 108. 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. The first housing 104 and the second housing 106 can be engaged with each other using a known structure. Specifically, the first housing 104 may be fitted to the second housing 106, or may be engaged by snap-fitting with hooks or the like, or may be engaged by the magnetic force of a magnet.

[0031] The material of the housing 102 may be, for example, a metal such as aluminum, or a resin. Specific examples of resin include polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (Polyether Ether Ketone), and a polymer alloy containing multiple types of polymers.

[0032] The first housing 104 has an opening 110 through which the consumable item 120 can be inserted, and the slide cover 108 is slidably attached to the first housing 104 to close the opening 110. Specifically, the slide cover 108 is configured to be movable along the outer surface of the first housing 104 between a closed position that closes the opening 110 of the first housing 104 and an open position (the position shown in FIGS. 1 and 2) that opens the opening 110. 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 item 120 to the interior of the flavor inhaler 100.

[0033] 1 and 2 illustrate the housing 102 of the flavor inhaler 100 such that the joint surface between the first housing 104 and the second housing 106 extends substantially parallel to the XY plane, but the configuration of the housing 102 is not limited to this. For example, the joint surface may extend so as to be inclined with respect to the XY plane. In the example shown in FIGS. 1 and 2, the housing 102 is composed of only the first housing 104 and the second housing 106. In other words, the upper end t1 of the housing 102 is located in the first housing 104, and the lower end b1 is located in the second housing 106. However, the housing 102 may be composed of three or more members.

[0034] 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.

[0035] 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, a heating assembly 30, and a control unit 80 are provided in the internal space of the housing 102 of the flavor inhaler 100.

[0036] The control unit 80 includes a circuit board 82. The circuit board 82 includes, for example, a microprocessor and can control the supply of power from the power supply unit 20 to the heating assembly 30. This allows the control unit 80 to control the heating of the consumable 120 by the heating assembly 30. The control unit 80 may also include a Bluetooth (registered trademark) interface 28. The control unit 80 can communicate with external devices via the Bluetooth interface 28.

[0037] The power supply unit 20 includes a battery 21 electrically connected to a circuit board 82 of the control unit 80. The battery 21 may be, for example, a rechargeable battery or a non-rechargeable battery. The battery 21 is electrically connected to the heating assembly 30 via the circuit board 82. This allows the battery 21 to supply power to the heating assembly 30 so as to appropriately heat the consumable item 120.

[0038] The heating assembly 30 includes a chamber 50 extending in the longitudinal direction of the consumable 120, a heating section (not shown) surrounding a portion of the chamber 50, a heat insulating section 32, and a generally cylindrical insertion guide member 34. The chamber 50 is configured to house the consumable 120. The heating section is configured to contact, for example, the outer peripheral surface of the chamber 50 and heat the consumable 120 housed in the chamber 50. As an example, a susceptor may be provided inside or around the consumable 120, and the heating section may include an induction coil for inductively heating the susceptor.

[0039] 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 120 into the chamber 50 by inserting the consumable 120 into the insertion guide member 34.

[0040] 1 to 3 , when the housing 102 is composed of multiple components (a first housing 104 and a second housing 106), it is preferable to prevent liquid from entering the housing 102 through gaps between the components. Therefore, the flavor inhaler 100 according to this embodiment is characterized by the structure of the first housing 104.

[0041] FIG. 4 is a partial cross-sectional view of the housing 102. Specifically, FIG. 4 shows a cross-section (X-Z cross-section) perpendicular to a first outer surface 61 and a second outer surface 71 (described later) of the housing 102, extending between the upper end t1 and the lower end b1 of the housing 102. As shown in FIG. 4, the first housing 104 has a first wall 60 extending between the upper end t1 and the lower end b1. The first wall 60 has a first outer surface 61 and a first inner surface 62. The first outer surface 61 constitutes a portion of the outer surface of the housing 102, and the first inner surface 62 constitutes a portion of the inner surface of the housing 102. In this embodiment, in the cross-section shown in FIG. 4, a first end 61a on the lower end side of the first outer surface 61 is located closer to the lower end b1 than a second end 62a on the lower end side of the first inner surface 62. The first housing 104 also has a first end surface 63 connecting the first end 61a and the second end 62a. As a result, the first outer surface 61 of the first housing 104 near the mouthpiece extends further toward the lower end b1 than the first inner surface 62, so that when the flavor inhaler 100 is gripped, liquids such as rain flowing from above can be prevented from entering through the gap between the first housing 104 and the second housing 106.

[0042] 4 may be a cross section parallel to the insertion direction of the consumable 120. The direction parallel to the insertion direction of the consumable 120 is usually oriented substantially vertically when the user uses (smokes) the flavor inhaler 100. Therefore, in the direction parallel to the insertion direction of the consumable 120, the first end 61a is positioned closer to the lower end b1 than the second end 62a, which further prevents liquids such as rain flowing from above from entering through the gap between the first housing 104 and the second housing 106 when the flavor inhaler 100 is held.

[0043] It is preferable that the first end surface 63 extends around the entire circumference of the first housing 104. In this case, the first outer surface 61 extends further toward the lower end b1 than the first inner surface 62 around the entire circumference of the first housing 104, which further prevents liquid such as rain flowing from above from entering through the gap between the first housing 104 and the second housing 106 when the flavor inhaler 100 is gripped. However, the first end surface 63 may extend partially around the circumference of the first housing 104.

[0044] 4, the first end 61a preferably extends 0.3 mm or more toward the lower end b1 than the second end 62a. In this case, the first end 61a extends a sufficient distance toward the lower end b1 than the second end 62a, which further prevents rain or other liquids flowing from above from entering through the gap between the first housing 104 and the second housing 106 when the flavor inhaler 100 is held.

[0045] In the example shown in FIG. 4 , the first end surface 63 is flat. In this case, the angle between the first outer surface 61 and the first end surface 63 is preferably 30° or greater and 75° or less. If the angle is less than 30°, the lower end of the first wall 60 may become too thin, potentially resulting in insufficient strength of the lower end of the first wall 60. If the angle is greater than 75°, the difference in vertical position between the first end 61 a and the second end 62 a may become small, potentially resulting in insufficient prevention of liquid from entering the housing 102. Therefore, if the angle is within the above numerical range, it is possible to prevent liquid from entering the housing 102 while preventing a decrease in the strength of the lower end of the first wall 60.

[0046] As shown in FIG. 4 , the second housing 106 has a second wall 70 extending between an upper end t1 and a lower end b1. The second wall 70 has a second outer surface 71 and a second inner surface 72. The second outer surface 71 constitutes a portion of the outer surface of the housing 102, and the second inner surface 72 constitutes a portion of the inner surface of the housing 102. In this embodiment, in the cross section shown in FIG. 4 , a third end 71 a on the upper side of the second outer surface 71 is located closer to the lower end b1 than a fourth end 72 a on the upper side of the second inner surface 72. The second housing 106 also has a second end surface 73 connecting the third end 71 a and the fourth end 72 a, and the first end surface 63 and the second end surface 73 are disposed opposite each other. In this case, the shape of the second wall 70 of the second housing 106 can be formed to correspond to the shape of the first wall 60 of the first housing 104, thereby further preventing liquid from entering through the gap between the first housing 104 and the second housing 106.

[0047] It is preferable that the second end surface 73 extend around the entire circumference of the second housing 106. In this case, the shape of the second wall 70 of the second housing 106 can be formed to correspond to the shape of the first wall 60 of the first housing 104 around the entire circumference of the second housing 106, which further prevents liquid from seeping in through the gap between the first housing 104 and the second housing 106. However, the second end surface 73 may extend partially in the circumferential direction of the second housing 106.

[0048] The gap between the first end face 63 and the second end face 73 is preferably 0.1 mm or more and 0.5 mm or less. If the gap is less than 0.1 mm, the gap between the first end face 63 and the second end face 73 will be too small. Depending on the manufacturing tolerance of the housing 102, the first end face 63 and the second end face 73 may come into contact, which may prevent the first housing 104 and the second housing 106 from being properly assembled. Furthermore, if the gap exceeds 0.5 mm, the gap between the first end face 63 and the second end face 73 will be too large, which may result in insufficient prevention of liquid intrusion into the housing. Therefore, as long as the gap is within the above numerical range, it is possible to prevent the intrusion of liquid into the housing 102 while suppressing assembly defects of the housing 102. The gap between the first end face 63 and the second end face 73 need not be substantially nonexistent.

[0049] As shown in FIG. 4 , the second end surface 73 is flat. In this case, the angle between the second outer surface 71 and the second end surface 73 is preferably 105° or greater and 150° or less. If the angle is less than 105°, the difference in vertical position between the third end 71a and the fourth end 72a becomes small, which may result in insufficient prevention of liquid from entering the housing 102. If the angle is greater than 150°, the upper end of the second wall 70 may become too thin, which may result in insufficient strength of the upper end of the second wall 70. Therefore, as long as the angle is within the above numerical range, it is possible to prevent liquid from entering the housing 102 while preventing a decrease in the strength of the upper end of the second wall 70.

[0050] As described above, the flavor inhaler 100 includes the heating assembly 30 housed in the housing 102 and configured to heat the consumables 120, and the battery 21 housed in the housing 102 and supplying power to the heating assembly 30. Therefore, according to this embodiment, when the flavor inhaler 100 is held, it is possible to prevent liquid such as rain flowing from above from entering through the gap between the first housing 104 and the second housing 106, thereby preventing failure of the heating assembly 30 and the battery 21 housed in the housing 102.

[0051] 5 and 6 are partial cross-sectional views of a housing 102 according to another embodiment. The examples shown in FIGS. 5 and 6 differ from the example shown in FIG. 4 in the shapes of the first end surface 63 and the second end surface 73. In the example shown in FIG. 5, the first end surface 63 and the second end surface 73 are curved rather than flat. In the example shown in FIG. 5, the first end surface 63 and the second end surface 73 are curved so as to be convex toward the upper end t1, but this is not limited thereto, and they may be curved so as to be convex toward the lower end b1. Furthermore, in the example shown in FIG. 6, the first end surface 63 and the second end surface 73 are not flat but are formed in a stepped shape.

[0052] Only one of the first end surface 63 and the second end surface 73 may be curved, or only one of them may be formed in a stepped shape. The shapes of the first end surface 63 and the second end surface 73 disclosed in Figures 4 to 6 may be combined in any manner.

[0053] 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.
