Definitions

  • the present invention relates to a flavor inhaler.
  • the flavor inhaler for inhaling flavors and the like without burning any material.
  • the flavor inhaler has, for example, a chamber that contains a flavor-generating article, and a heater that heats the flavor-generating article contained in the chamber (see, for example, Patent Document 1).
  • the housing that houses the heater and 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.
  • One of the objectives of the present invention is to prevent liquid from entering the interior of a flavor inhaler housing made up of multiple parts through gaps between the parts.
  • a 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 has 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.
  • the first outer surface of the first housing which is closer to the mouthpiece, extends further down 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 and second housings.
  • the first end may extend 0.3 mm or more toward the lower end than the second end.
  • the first end extends downward a sufficient distance beyond the second end, which further prevents rain or other liquids flowing from above from entering through the gap between the first and second housings when the flavor inhaler is held.
  • 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, 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, the second housing has a second end surface connecting the third end surface and the fourth end surface, and the first end surface and the second end surface may be arranged opposite each other.
  • 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, which further prevents liquid from entering through the gap between the first and second housings.
  • the gap between the first end face and the second end face may be 0.1 mm or more and 0.5 mm or less.
  • 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 impossible to properly assemble the first housing and the second housing. 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 impossible to sufficiently 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 preventing housing assembly defects.
  • 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 prevented. If the angle is more than 150°, the upper end of the second wall will become 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 prevent the intrusion of liquid into the housing while preventing a decrease in the strength of the upper end of the second wall.
  • the device may include a heating assembly housed in the housing and configured to heat a consumable, and a battery housed in the housing and configured to power the heating assembly.
  • the housing may have an opening through which a consumable can be inserted, and the cross section may be parallel to the direction in which the consumable is inserted.
  • the direction parallel to the insertion direction of the consumable is usually oriented approximately vertically when the user uses (smokes) the flavor inhaler. Therefore, in the direction parallel to the insertion direction of the consumable, the first end is located closer to the bottom end than the second end, which further prevents liquids such as rain flowing from above from entering through the gap between the first and second housings when the flavor inhaler is held.
  • the upper end may be located in the first housing, and the lower end may be located in the second housing.
  • the housing can be composed of only the first housing and the second housing.
  • the first end face may extend around the entire circumference of the first housing.
  • the first outer surface extends further down than the first inner surface around the entire circumference of the first housing, which further prevents rain or other liquids flowing from above from entering through the gap between the first and second housings when the flavor inhaler is gripped.
  • FIG. 1 is a perspective view of a flavor inhaler according to an embodiment of the present invention.
  • FIG. 2 is a perspective view of a flavor inhaler containing a consumable product inserted through an opening.
  • 3 is a cross-sectional view of the flavor inhaler taken along the arrow 3-3 in FIG. 1.
  • FIG. 11 is a partial cross-sectional view of a housing according to another embodiment.

  • the Z axis faces vertically upward, the X-Y plane is arranged to cut the flavor inhaler 100 horizontally, and the Y axis is arranged 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 120 contained in the chamber 50 described later.
  • the X-axis direction can also be referred to as the device longitudinal direction in a plane perpendicular to the insertion direction of the consumable 120.
  • the Y-axis direction can also be referred to as the device lateral direction in a plane perpendicular to the insertion direction of the consumable 120.
  • the flavor inhaler 100 is configured to generate an aerosol containing a flavor by, for example, heating a stick-shaped consumable 120 having a flavor source containing an aerosol source.
  • the consumable 120 may be, for example, a cigarette having a smokable article containing a flavor source such as tobacco and an aerosol source at the tip in the negative Z-axis direction and a filter at another location.
  • the aerosol source include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. Note that, in this embodiment, the consumable 120 is described as having a stick shape, but the consumable 120 used in the flavor inhaler 100 is not limited to this.
