An aerosol-generating apparatus includes a mouthpiece, an aerosolizing thermal reactor, and an air preheating passage. The aerosolizing thermal reactor has an air inlet upstream of an aerosol outlet, and includes an aerosolizable substance chamber and a thermal distribution casing. The thermal distribution casing surrounds the aerosolizable substance chamber and includes a laminate material with an at least three-layer construction including a metal middle layer between a metal outer layer and a metal inner layer. The thermal conductivity of the metal inner layer is at least double that of each of the metal outer and inner layers. The air preheating passage is located downstream of the air inlet and upstream of the aerosolizable substance chamber, and surrounds the aerosolizable substance chamber. The air preheating passage is defined by an air gap between the chamber outer wall and the metal inner layer.

An inhaler system suitable for providing nicotine particles includes a mouthpiece portion removably coupled to a distal end portion. The mouthpiece portion includes a capsule cavity and a mouthpiece air channel extending from the mouthpiece end to the capsule cavity. The distal end portion includes a piercing element coupled to the distal end portion and a resealable membrane configured to seal the capsule cavity when the mouthpiece portion is coupled to the distal end portion. The resealable membrane is configured to reseal when the piercing element moves out of the resealable membrane.

An indirect exothermal vaporization matrix for selective vaporization and/or atomization of compounds is provided. The matrix may incorporate any one or more of the following features: capillary structures, vapor relief pathways, carbon filtering, recessed receiving areas, torus and tori geometry to provide uniform loading and/or reloading of the indirect exothermal vaporization matrix with various compounds, and the like.

Present invention teaches a mechanical vaporizer primarily consisting of a mouth piece, an outer tube, and inner tube wrapped by a spring. A heat sink provides the insolation between the outer tube and the heating chamber that contains a side window to show temperature by the length extension of a sensing coil and allows easy removal of used vaping material to be removed.

Described herein are reservoir-less vaping-alternative devices. A device may include a housing defining a first cavity therein and including a valve assembly. The first cavity of the housing is in fluid communication with an environment external to the housing via the valve assembly. A device may further include a cap defining a second cavity and a first end defining a first aperture, and a second end defining a second aperture. The first end is for interaction with a mouth of a user and the second end is reversibly couplable to the housing. The cap cavity is in fluid communication with the housing cavity when the second end of the cap is coupled to the housing. A device may further include at least one wick pre-soaked in a fluid and positioned in the cap.

An inhaler comprising an elongate housing containing a reservoir of inhalable composition. An outlet for the composition and suction port are provided at one end of the housing. A diaphragm is mounted in the housing defining a suction chamber such that suction on the suction port reduces the size of the suction chamber. An elongate leaf spring is mounted at one end to the housing at the end of the suction chamber opposite to the suction port, and is pivotally mounted at an intermediate portion about a pivot point. A valve element is at the end of the leaf spring opposite to the one end and is biased closed. Suction on the suction port deflects the diaphragm and hence the leaf spring between the one end and the pivot point causing the opposite end of the leaf spring to pivot about the pivot point thereby causing the valve element to open.
