Abstract: An electronic smoking device, comprising a capillary buffer having a first end, a second end, a capillary buffer portion between the first end and a second end, and a vapor channel and a liquid conduit formed between first end and the second end and through the capillary buffer portion; the capillary buffer portion is operable to receive under capillary effect excessive liquid from the liquid supply.

Abstract: A liquid supply for electronic smoking device has a compartment (102) within a housing (100). A reservoir (200) is provided in the compartment (102) for storing liquid, with at least one portion the reservoir (200) attached to the housing (100). The reservoir (100) contracts as liquid flows out of the reservoir (200). The reservoir (200) does not collapse or fold as it contracts, to avoid interfering with outflow of liquid. The reservoir (200) may comprise an elastomeric material, such as rubber. The reservoir (200) may be pretensioned or elastically stretched when filled with liquid. The reservoir (200) then exerts an elastic compression force on the liquid in the reservoir (200).

Abstract: An electronic cigarette including a liquid supply, an air inlet, an inhalation port, and an atomizer. The liquid supply has a housing with a spiral container, having an outlet for directing a liquid held within the container out to the atomizer and at least one inlet sealed by a sealing agent to impede movement of the liquid. An air channel leads from the air inlet through the atomizer to the inhalation port for directing an aerosol generated at the atomizer to the inhalation port.

Abstract: A liquid supply for an electronic smoking device has a liquid reservoir (110) within a housing (100) for holding a liquid. A buffering channel (120) within or on the housing (100) connects into the liquid reservoir (110) via a port (130). A sealing member (140) is fitted within the buffering channel (120) and provides a movable or slidable seal in the buffering channel (120). Upon expansion of a gas within the liquid reservoir (110) and/or a gaseous component within the liquid, the sealing member (140) moves within the buffering channel (120) to increase the effective volume of the liquid reservoir (110) and compensate for the change in pressure. Over-pressure and under-pressure conditions in the liquid reservoir are reduced or avoided.
