Abstract

Official abstract text for this publication.

A smoking substitute apparatus comprises: a vaporization chamber having a longitudinal axis, the vaporization chamber having an inlet at a first end and an outlet at a second end opposite the first end. The inlet is configured to be in fluid communication with an outlet though a flow channel extending along the longitudinal axis of the vaporization chamber. A heater is located in the vaporization chamber at a position along the flow channel. The heater is configured to generate an aerosol from an aerosol precursor. The heater is spaced from the inlet by a distance of at least 5 mm.

First claim

Opening claim text (preview).

What is claimed is: 1 . A smoking substitute apparatus comprising: a vaporization chamber having a longitudinal axis, the vaporization chamber having an inlet at a first end and an outlet at a second end opposite the first end; wherein the inlet is configured to be in fluid communication with an outlet though a flow channel extending along the longitudinal axis of the vaporization chamber; and an aerosol generator in the vaporization chamber at a position along the flow channel; and wherein the aerosol generator is spaced from the inlet by a distance of at least 5 mm; wherein the vaporization chamber between the inlet and the aerosol generator comprises a first outwardly tapered portion having a first width at a first end nearest the inlet and a second width at a second end nearest the aerosol generator, wherein the second width is greater than the first width, and wherein the vaporization chamber between the inlet and the aerosol generator comprises a portion having a substantially constant width downstream of the first outwardly tapered portion. 2 . A smoking substitute apparatus according to claim 1 , wherein the aerosol generator is spaced from the inlet by a distance of up to 12 mm. 3 . A smoking substitute apparatus according to claim 1 , wherein the aerosol generator is spaced from the inlet by a distance of substantially 10 mm. 4 . A smoking substitute apparatus according to claim 1 , comprising a heater, and wherein the portion having a substantially constant width has a width which is greater than a diameter of the heater. 5 . A smoking substitute apparatus according to claim 1 , wherein the vaporization chamber between the inlet and the aerosol generator comprises a second outwardly tapered portion, wherein the portion having a substantially constant width is between the first outwardly tapered portion and the second outwardly tapered portion. 6 . A smoking substitute apparatus according to claim 1 , wherein the aerosol generator is orthogonal to the longitudinal axis. 7 . A smoking substitute apparatus according to claim 1 , wherein the aerosol generator comprises a wick extending orthogonally to the longitudinal axis of the vaporization chamber and a heater is wound around the wick. 8 . A smoking substitute system comprising: a main body; and a smoking substitute apparatus, the smoking substitute apparatus comprising: a vaporization chamber having a longitudinal axis, the vaporization chamber having an inlet at a first end and an outlet at a second end opposite the first end; wherein the inlet is configured to be in fluid communication with an outlet though a flow channel extending along the longitudinal axis of the vaporization chamber; and an aerosol generator in the vaporization chamber at a position along the flow channel; and wherein the aerosol generator is spaced from the inlet by a distance of at least 5 mm; wherein the vaporization chamber between the inlet and the aerosol generator comprises a first outwardly tapered portion having a first width at a first end nearest the inlet and a second width at a second end nearest the aerosol generator, wherein the second width is greater than the first width, and wherein the vaporization chamber between the inlet and the aerosol generator comprises a portion having a substantially constant width downstream of the first outwardly tapered portion. 9 . A smoking substitute apparatus according to claim 4 , wherein the vaporization chamber between the inlet and the aerosol generator comprises a second outwardly tapered portion, wherein the portion having a substantially constant width is between the first outwardly tapered portion and the second outwardly tapered portion. 10 . A smoking substitute apparatus according to claim 2 , wherein the aerosol generator is orthogonal to the longitudinal axis. 11 . A smoking substitute apparatus according to claim 2 , wherein the aerosol generator comprises a wick extending orthogonally to the longitudinal axis of the vaporization chamber and a heater is wound around the wick. 12 . A smoking substitute apparatus according to claim 3 , wherein the aerosol generator is orthogonal to the longitudinal axis. 13 . A smoking substitute apparatus according to claim 3 , wherein the aerosol generator comprises a wick extending orthogonally to the longitudinal axis of the vaporization chamber and a heater is wound around the wick. 14 . A smoking substitute apparatus according to claim 4 , wherein the aerosol generator is orthogonal to the longitudinal axis. 15 . A smoking substitute apparatus according to claim 4 , wherein the aerosol generator comprises a wick extending orthogonally to the longitudinal axis of the vaporization chamber and a heater is wound around the wick. 16 . A smoking substitute apparatus according to claim 6 , wherein the aerosol generator comprises a wick extending orthogonally to the longitudinal axis of the vaporization chamber and a heater is wound around the wick.
