Definitions

  • the present invention relates to a cartridge for an inhalation device such as a device for heating a consumable substance like a liquid which can be vaporized.
  • Such devices can have a heater part with a heater and a consumable part adapted to house a consumable substance, e.g. a liquid to be vaporized.
  • the cartridge is suitable to be used with an inhalation device having a heater, which can be brought into contact with a membrane adapted to transfer heat from the heater to the wick.
  • the heater is part of a heater part of the device, and the cartridge described herein comprises, amongst further components described below, a wick which is sufficiently solid to be clamped, and the mentioned membrane.
  • the heater is thus comprised in the device.
  • the cartridge extends along a cartridge axis which can, for example, be substantially the direction, in which vapor can be drawn from the device, in particular the cartridge, which, accordingly, preferably forms a suitable mouthpiece.
  • the cartridge generally has an elongate appearance, with the longitudinal axis typically corresponding to the flowing direction of air and vapor drawn from the cartridge, and the mentioned longitudinal axis essentially corresponds to the cartridge axis.
  • the mentioned surfaces, between which the membrane and the wick are clamped can efficiently be provided on the clamping component.
  • the clamping component can for example be injection molded.
  • a piece of a different material, such as a ceramic ring can be inserted before injection molding or can be combined with the clamping component in any other suitable manner as described in more detail below.
  • the membrane and the wick can be clamped between the mentioned surfaces with further components optionally being present between one or both of the surfaces and the membrane and the wick, respectively.
  • a particularly efficient arrangement is realized, when clamping is effected directly between the clamping component and the wick.
  • the wick is suitably supported directly or indirectly, e.g. with a seal in between, at a surface of the clamping component extending transversally with respect to the cartridge axis, and the second surface of the clamping component extending transversally with respect to the cartridge axis directly contacts the membrane and clamps same against the wick. Consequently, a surface pressure sufficient to allow good heat transfer is present between the mentioned surfaces and the wick and the membrane respectively, as well as, as a consequence, between the membrane and the wick.
  • Such a piece of different material can for example be ring-shaped, in order to provide an efficient clamping surface for a, for example, circular shaped membrane, and/or such a piece of different material can be made of ceramic in order to increase durability. This is, because ceramic will be able to withstand high thermal stress, which is expected to be present at the interface between the surface clamping the membrane to the wick on the one hand and the membrane on the other hand.
