Abstract
An aerosol generating device defines a flow path from an air inlet to an inhalable medium outlet. The device includes a container for containing a liquid; a wick for drawing liquid from the container into the flow path, and a heating element, upstream of the wick, for heating inlet air from the air inlet to generate a flow of heated air in the flow path in use. The device is arranged such that, in use, the flow of heated air generated in use passes over the wick to volatilize the liquid to generate, in use, a flow of aerosol in the flow path. The device includes a receiving portion in the flow path, downstream of the wick, for receiving an element for modifying a property of the flow of aerosol. A device including a shield element to shield the wick from a heating element is also disclosed.
Claims16
An aerosol generating device defining a flow path from an air inlet to an inhalable medium outlet, the aerosol generating device comprising:
- a container for containing a liquid;
- a wick for drawing the liquid from the container into the flow path;
- a heating element, upstream of the wick, for heating inlet air from the air inlet to generate, in use, a flow of heated air in the flow path;
- and
- a shield element in the flow path, intermediate of the heating element and the wick, to shield the wick from the heating element,
- wherein the aerosol generating device is arranged such that, in use, the flow of heated air generated in use passes over the wick to volatilize the liquid to generate, in use, a flow of aerosol in the flow path, and
- wherein the shield element blocks a line of sight from the heating element to the wick and the inhalable medium outlet;
- wherein the shield element comprises a first element extending across a first portion of a cross section of the flow path and a second element, downstream of the first element, extending across a second portion of the cross section of the flow path, and wherein at least some of the second portion is different from the first portion.
An aerosol generating article for an aerosol generating device, the aerosol generating article defining a flow path from a heated air inlet for intake of a flow of heated air generated in use to an inhalable medium outlet, the aerosol generating article comprising:
- a container for containing a liquid;
- a wick, downstream of the heated air inlet, for drawing the liquid from the liquid container into the flow path, wherein the aerosol generating article is arranged such that, in use, the flow of heated air generated in use passes over the wick to volatilize the liquid to generate, in use, a flow of aerosol in the flow path;
- and
- a shield element in the flow path, upstream of the wick, to shield the wick from a heating element of the aerosol generating device generating the flow of heated air in use,
- wherein the shield element blocks a line of sight from the heating element to the wick and the inhalable medium outlet;
- wherein the shield element comprises a first element extending across a first portion of a cross section of the flow path and a second element, downstream of the first element, extending across a second portion of the cross section of the flow path, and wherein at least some of the second portion is different from the first portion.
