Abstract: There is provided an electronic smoking device (10; 110; 210; 310) comprising a power supply (18), a liquid reservoir (34; 34; 234; 334) storing a liquid, and an atomizer (26). The atomizer (26) is adapted to atomize the liquid stored in the liquid reservoir (34; 34; 234; 334) when operated by the power supply (18). The liquid reservoir (34; 34; 234; 334) comprises a first chamber (40) storing the liquid, which first chamber (40) has a variable volume that is reducible and non-increasable.

Abstract: The present invention concerns an electronic smoking device that includes a battery portion (12) comprising a battery (18), an atomizer/liquid reservoir portion (14) comprising a multicameral liquid reservoir (34), and an atomizer (26) operable when connected to the battery (18) to atomize liquid stored in the multicameral liquid reservoir (34). The multicameral liquid reservoir (34) comprises a first chamber (202) comprising an unflavored fluid, a second chamber (204) comprising a flavored fluid, the first chamber (202) and the second chamber (204) being disposed in communication with each other via an opening (206), and a plurality of reservoir walls (208) enclosing the two chambers. A portion of the plurality of reservoir walls (208) enclosing the second chamber (204) comprising a flexible portion (40), the flexible portion (40) when acted upon causing the flavored fluid to migrate from the second chamber (204) to the first chamber (202) through the opening (206).

Abstract: An electronic smoking device (10) includes a battery portion (12) including an electric power source (18), an atomizer/liquid reservoir portion (14) having a mouthpiece opening (36) in an end, a liquid reservoir (34) for accommodating a liquid, and a glass capillary tube (46). The glass capillary tube (46) comprises a first open end (48) arranged inside the liquid reservoir (34) and an outlet portion (50), wherein the glass capillary tube (46) is adapted to transport liquid from the first open end (48) to the outlet portion (50) by capillary force. The electronic smoking device (10) further includes an atomizer (26) arranged at the outlet portion (50) such that is operable to vaporize liquid at the outlet portion (50) to create an aerosol.

Abstract: There is provided a liquid reservoir for an electronic smoking device. The liquid reservoir (34) has a body (110) forming a hollow tube surrounding a central passage (32) connecting an air inhalation port (36) with a further port for attaching the liquid reservoir (34) to a further portion of the electronic cigarette (10). The liquid reservoir (34) further has a nozzle (132) towards the central passage (32), the nozzle (32) being configured to release liquid from the reservoir (34) only when pressure drop along the nozzle (32) exceeds a threshold pressure. A user can produce the pressure drop by sucking at the air inhalation port (36) and/or by manually changing a length of the central passage (32) thereby causing compression of the liquid reservoir (34).
