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.
Claims10
An electronic smoking device comprising:
- a power supply;
- a liquid reservoir configured for storing a liquid, wherein the liquid reservoir comprises a chamber for storing the liquid, and wherein the chamber has a variable volume that is reducible and non-increasable, wherein the liquid reservoir comprises a hollow cylindrical body including the first chamber;
- a piston inserted into an open end of the hollow cylindrical body, wherein the piston is configured to be moved into the hollow cylindrical body to reduce the volume of the chamber, and wherein the piston is mechanically connected with a blocking unit that is configured to prevent movement of the piston out of the cylindrical hollow body, the blocking unit including a stepped portion on an inner wall of the cylindrical hollow body, wherein the step portion engages with a biased blocking element that protrudes from the piston;
- and
- an atomizer adapted to atomize the liquid stored in the liquid reservoir when operated by the power supply.
A liquid reservoir portion for an electronic smoking device, the liquid reservoir portion comprising:
- a first chamber for storing the liquid, and wherein the first chamber has a variable volume that is reducible and non-increasable, and wherein, wherein the liquid reservoir comprises a hollow cylindrical body including the first chamber;
- and
- a piston inserted into an open end of the hollow cylindrical body, wherein the piston is configured to be moved into the hollow cylindrical body to reduce the volume of the first chamber, and wherein the piston is mechanically connected with a blocking unit that is configured to prevent movement of the piston out of the cylindrical hollow body, the blocking unit including a stepped portion on an inner wall of the cylindrical hollow body, wherein the step portion engages with a biased blocking element that protrudes from the piston.
