The method includes first defining a first reservoir and a second reservoir within a housing of a cartridge, the second reservoir being in fluid communication with the first reservoir, inserting at least one first layer of absorbent material within the first reservoir, and arranging a heater and a wick to be in communication with a central channel, the wick being in contact with the absorbent material.

An electronic cigarette system including a liquid capsule having a reservoir for holding vaporizable material, a holder-facing surface, a vapor pipe with an vapor inlet at the holder-facing surface, an inhalation opening, a liquid exit port arranged at the holder-facing surface, and a capsule holder for removably receiving the liquid capsule. The capsule holder including a capsule accommodating opening, a heating device, and a mesh for being soaked with the vaporizable material. When the liquid capsule and the capsule holder are interconnected to each other, a fluid chamber is formed between an outer surface the capsule accommodating opening and the holder-facing surface and when the liquid capsule and the capsule holder are interconnected to each other, a fluidic connection path is formed from the reservoir to the fluid chamber via the liquid exit port, to reach the inhalation opening.

A cartridge for an e-vaping device includes a reservoir configured to hold a pre-vapor formulation and a channel structure that includes a channel surface with one or more open-microchannels. An open-microchannel in the channel structure may be in fluid communication with the reservoir and may transport pre-vapor formulation from the reservoir to a heating element based on capillary action of the pre-vapor formulation through the open-microchannels. The heating element may vaporize the pre-vapor formulation drawn through one or more open-microchannels. The cartridge may be independent of fibrous dispensing interfaces, including one or more wicks. Fabrication of such a cartridge may be simplified, faster, cheaper, some combination thereof, or the like relative to fabrication of a cartridge that includes a fibrous or soft dispensing interface to draw pre-vapor formulation from a reservoir to a heating element.

A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

A portable liquid vaporizer (1) comprises a reservoir (10) for holding a liquid to be vaporized; a heater (12) for vaporizing the liquid; a mouthpiece (3) for withdrawing the vapor; and an air path (30) extending through the vaporizer (1), comprising a heating section (31) and a cooling section (32), wherein the heating section (31) extends along the heater (12) and the cooling section (32) extends directly downstream from the heater (12) to the mouthpiece (3).

A method of reducing the quantity of a first constituent in aerosol generating material using an aerosol generating device configured to deliver inhalable aerosol to a user is disclosed. The method comprises performing a first aerosolization process on a portion of the aerosol generating material comprising the first constituent to generate an aerosol for user inhalation, and performing a second aerosolization process on at least the portion of the aerosol generating material until the at least the portion of the aerosol generating material is substantially free of the first constituent. Also provided is an aerosol provision device and an aerosol provision system.
