Abstract
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.

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.
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.
