Abstract
An aerosol source for an electronic vapor provision system includes a heating element; an atomizing chamber; a reservoir for holding free-flowing source liquid; and a porous wick extending from the atomizing chamber to the reservoir and comprising a heater portion in cooperation with the heating element within the atomizing chamber and at least one liquid collecting portion within the reservoir, the liquid collecting portion having a maximum cross-sectional parameter that is greater than an equivalent cross-sectional parameter of the heater portion.
Claims20
An aerosol source for an electronic vapor provision system comprising:
- a heating element;
- an atomizing chamber;
- a reservoir for holding free-flowing source liquid;
- a porous wick extending from the atomizing chamber to the reservoir and comprising a heater portion in cooperation with the heating element within the atomizing chamber such that the heating element is external to the heater portion or disposed within the heater portion, and at least one liquid collecting portion within the reservoir, the at least one liquid collecting portion having a maximum perimeter that is greater than a perimeter of the heater portion;
- wherein the porous wick is formed from a porous non-fiber-based material with integral interstitial pores.
An atomizer for an electronic vapour provision system comprising:
- a heating element;
- and
- a porous wick comprising a heater portion in cooperation with the heating element such that the heating element is external to the heater portion or disposed within the heater portion, and at least one liquid collecting portion contiguous with the heater portion for placement in a reservoir of source liquid, the at least one liquid collecting portion having a maximum perimeter that is greater than a perimeter of the heater portion;
- wherein the porous wick is formed from a porous non-fiber-based material with integral interstitial pores.
A wick for an atomizer of an electronic vapor provision system, made from porous non-fiber-based material with integral interstitial pores and comprising:
- a heater portion for cooperation with a heating element formed as a wire such that the heating element is external to the heater portion or disposed within the heater portion;
- and
- at least one liquid collecting portion contiguous with the heater portion for placement in a reservoir of source liquid, the at least one liquid collecting portion having a maximum perimeter that is greater than a perimeter of the heater portion.
