A vaporizer includes: an air inlet; an air outlet; an airflow channel in communication with the air inlet and the air outlet, respectively, a vaporization core being arranged in the airflow channel; a first capillary liquid absorbing structure and a second capillary liquid absorbing structure, the first capillary liquid absorbing structure and the second capillary liquid absorbing structure being arranged in the airflow channel provided between the air inlet and the vaporization core, the first capillary liquid absorbing structure being arranged between the vaporization core and the second capillary liquid absorbing structure; and a gap between the first capillary liquid absorbing structure and the second capillary liquid absorbing structure so as to allow air entering from the air inlet to reach the vaporization core after flowing through the gap and the first capillary liquid absorbing structure sequentially.

In one aspect, apparatus is provided for generating an inhalable medium. The apparatus has a container for holding a liquid and a heater for volatilizing liquid held in the container. The apparatus further has a chamber for receiving a material. The apparatus has an outlet. In use liquid volatilized by the heater passes, in the form of at least one of a vapor and an aerosol, through material received in the chamber to thereby entrain one or more constituents from the material to produce the inhalable medium which passes out of the outlet.

A method and device are provided for volatilizing active and/or aroma materials for releasing an inhalable aerosol, wherein a fluid flows through a flow channel in a preferably cylindrical hollow body, wherein the fluid in the flow channel entirely or in part flows through at least one vaporizer membrane in a fluid stream, wherein the at least one vaporizer membrane has been and/or is wetted with a substance containing an active and/or aroma material to be vaporized, and wherein the fluid additionally contains thermal energy and vaporizes the substance on flowing through the vaporizer membrane and supplies the vaporized substance to the fluid stream.

This non-combusting flavor inhaler is provided with a first flow path which is disposed downstream of a vaporizer unit, and, as an aerosol flow path, a second flow path which is disposed downstream of the first flow path. The second flow path houses a flavor source for imparting flavor to an aerosol. In order to suppress unevenness of aerosol flow in the second flow path, an aerosol flow adjustment chamber for adjusting flow of the aerosol supplied from the first flow path is provided between the first flow path and the second flow path.

A type flavor inhaler (100) comprises aerosol flow passage (140) guiding aerosol generated by the atomization unit (111) to the mouthpiece side. The aerosol flow passage (140) includes: a first flow passage (140A) which guides aerosol to the mouthpiece side through the flavor source (132); and a second flow passage (140B) which is different from the first flow passage (140A). An aerosol reduction rate of the second flow passage (140B) is smaller than an aerosol reduction rate of the first flow passage (140A).

A convection aromatherapy device is disclosed. The device has a body made of a suitable material, an air path for transfer of heat, and an electric cartridge heater. A source of heat, and/or hot air and device or means for selective vaporization of desirable compounds from various materials is thereby provided. A kit for convection aromatherapy is also provided.

In one aspect, apparatus is provided for generating an inhalable medium. The apparatus has a container for holding a liquid and a heater for volatilizing liquid held in the container. The apparatus further has a chamber for receiving a material. The apparatus has an outlet. In use liquid volatilized by the heater passes, in the form of at least one of a vapor and an aerosol, through material received in the chamber to thereby entrain one or more constituents from the material to produce the inhalable medium which passes out of the outlet.

An inhaler that includes a housing having a body configured to receive an active substance container containing an active substance, and an air channel extending within the housing; an administration element for nebulising or vaporising the active substance for mixing the active substance with air flowing in the air channel; an electronic control apparatus; an electronic data storage device; and a sensor system having a flow measuring apparatus for measuring a volume flow and a mass flow of the air and the active substance for storage as active substance delivery data; wherein: the electronic control apparatus is configured to convert active substance administration data into administration data to control the mixing of the active substance with the air; and the electronic control apparatus is configured to calculate a quantity of the active substance delivered from the active substance container and to compare the quantity with the active substance administration data.

An aerosol provision device for generating an inhalable aerosol comprises a housing containing a first chamber for containing a hot liquid. The housing also contains a second chamber for containing a substance that is heatable to generate the aerosol. The housing also contains a thermal energy transfer component for contacting the hot liquid when the hot liquid is contained in the first chamber to transfer thermal energy from the hot liquid to the substance when the substance is contained in the second chamber in order to heat the substance to generate the aerosol. The device comprises a mouthpiece comprising an outlet through which the aerosol may flow.
