Abstract

The invention relates to an electronic smoking device (100) with an atomizer/liquid reservoir portion (114) and to an atomizer/liquid reservoir portion (114). In order to facilitate refilling a liquid reservoir (134) of the atomizer/liquid reservoir portion (114), the atomizer/liquid reservoir portion (114) comprises a docking valve (146) for docking a source of liquid (148) to be stored in the liquid reservoir (134), and a liquid duct (156) that is adapted to receive liquid (172) from the docking valve (146) and that opens into the refillable liquid reservoir (134) at a predetermined distance (A) to the docking valve (146).

First claim

1 .- 14 . (canceled)

15 . An electronic smoking device, comprising:
a liquid reservoir adapted for storing liquid, an atomizer configured to atomize liquid stored in the liquid reservoir, and a central passage that is adapted to conduct atomized liquid, a docking valve for docking a source of liquid to be stored in the liquid reservoir, a liquid duct adapted to receive liquid from the docking valve and open into the refillable liquid reservoir, and a valve for releasing gas from the refillable liquid reservoir when refilling the refillable liquid reservoir, the valve comprising a flexible sealing element and a counter sealing element.

16 . The electronic smoking device according to claim 15 , wherein the liquid duct opens into the refillable liquid reservoir with an outlet orifice.

17 . The electronic smoking device according to claim 16 , wherein the outlet orifice is arranged closer to a side wall section of the refillable liquid reservoir opposite to the docking valve than to the docking valve.

18 . The electronic smoking device according to claim 15 , wherein the counter sealing element is formed by an outer side wall section of the central passage.

19 . The electronic smoking device according to claim 18 , wherein the section of the central passage that provides for the counter sealing element has a curved shape.

20 . The electronic smoking device according to claim 15 , wherein the liquid duct extends essentially perpendicular to and through the central passage at a convex section-of the central passage.

21 . The electronic smoking device according to claim 15 , wherein the electronic smoking device comprises a mouthpiece cap in communication with an air inhalation port for providing atomized liquid to a user, wherein the mouthpiece cap comprises a refill position and a vaping position, wherein in the vaping position, the mouthpiece cap is closer to an opposite end of the electronic smoking device than in the refill position.

22 . The electronic smoking device according to claim 21 , wherein the docking valve is covered by the mouthpiece cap in the vaping position, and is accessible when the mouthpiece cap is in the refill position.

23 . The electronic smoking device according to claim 21 , wherein the mouthpiece cap comprises a closing element that forces the flexible sealing element against the counter sealing element when the mouthpiece cap is in the vaping position.

24 . The electronic smoking device according to claim 23 , wherein the closing element is arranged at a distance to the flexible sealing element when the mouthpiece cap is in the refill position.

25 . The electronic smoking device according to claim 21 , wherein the mouthpiece cap is held in the refill position or in the vaping position in a force-fit manner or in a form-fit manner.

26 . The electronic smoking device according to claim 23 , wherein a latch element of a latch connection holding the mouthpiece cap in the vaping position or in the refill position is provided by the closing element, and a counter latch element-is provided by an outer side wall section of the central passage.

27 . The electronic smoking device according to claim 15 , wherein the docking valve is adapted to form a snap-fit connection with a counter docking valve of a source of liquid.

28 . The electronic smoking device according to claim 15 , wherein the docking valve has a docking section, the docking section comprising a convex or a concave shape.

29 . The electronic smoking device according to claim 15 , wherein the central passage extends through the refillable liquid reservoir.

30 . The electronic smoking device according to claim 15 , wherein the liquid duct opens into the refillable liquid reservoir at a predetermined distance to the docking valve.

31 . An atomizer/liquid reservoir portion comprising:
a liquid reservoir, an atomizer, and a central passage that is adapted to conduct atomized liquid, the central passage extending through the refillable liquid reservoir, wherein the atomizer/liquid reservoir portion comprises
a docking valve for docking a source of liquid to be stored in the liquid reservoir,
a liquid duct that is adapted to receive liquid from the docking valve and that opens into the refillable liquid reservoir at a predetermined distance (A) to the docking valve, and
a valve for releasing gas from the refillable liquid reservoir, the valve comprising a flexible sealing element and a rigid counter sealing element.

32 . The atomizer/liquid reservoir portion according to claim 31 , wherein the liquid duct opens into the refillable liquid reservoir with an outlet orifice.

33 . The atomizer/liquid reservoir portion according to claim 31 , wherein the rigid counter sealing element is formed by an outer side wall section of the central passage.

34 . The atomizer/liquid reservoir portion according to claim 31 , wherein the liquid duct extends essentially perpendicular to and through the central passage at a convex section-of the central passage.
