Improved inhalable delivery systems feature pens having functional and aesthetic improvements over those available commercially.

The present disclosure provides an aerosol precursor consumable, and an aerosol delivery device that comprises a control unit that defines a receiving chamber, and a removable and replaceable aerosol precursor consumable, at least a portion of the consumable configured to be received into the receiving chamber. The aerosol precursor consumable comprises a housing defining an outer wall, an aerosol precursor composition reservoir located in the housing and configured to contain an aerosol precursor composition, an atomizer located in the housing, and at least one aroma diffuser. The atomizer is configured to vaporize the aerosol precursor composition to generate an aerosol for oral delivery to a user, and the at least one aroma diffuser is configured to diffuse an aroma composition for olfactory delivery to the user.

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 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).

An aerosol provision system for generating aerosol for user inhalation is disclosed. The aerosol provision system comprises a replaceable part comprising a substrate providing aerosol generating material for generating the aerosol for user inhalation and a reusable part comprising: a housing including an interface configured to operatively engage with the replaceable part, and an air channel configured at least partially in the housing to provide a passage of air drawn by user inhalation to receive the aerosol generated from the aerosol generating material, a detector configured to detect the passage of air drawn through the air channel; at least one aerosol generating element disposed with respect to the interface and configured, in use, to generate aerosol from the aerosol generating material, and a control circuit configured to receive a signal from the detector indicating an amount of air drawn by the user and to control the at least one aerosol generating element to generate the aerosol selectively from different regions of the aerosol generating material in response to the amount of air drawn through the air channel.

An aerosol provision device for generating aerosol from an aerosol generating material is disclosed. The device comprises at least one heating element arranged so as to be adjacent aerosol generating material when the aerosol generating material is present in the aerosol provision device. The heating element has a surface arranged to increase in temperature when supplied with energy and the surface defines an area of no greater than 130 mm.sup.2 or 145 mm.sup.2. Also described is an aerosol provision system, and a method for generating aerosol.
