Electronic smoking device with a glass capillary tube
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.
1. An electronic smoking device, comprising:
a battery portion including an electric power source;
an atomizer/liquid reservoir portion having a mouthpiece opening in an end;
a liquid reservoir for accommodating a liquid;
a glass capillary tube;
wherein the glass capillary tube comprises a first open end arranged inside the liquid reservoir and an outlet portion, wherein the glass capillary tube is adapted to transport liquid from the first open end to the outlet portion by capillary force, and wherein the outlet portion comprises at least one opening in a peripheral surface of the glass capillary tube; and
an atomizer arranged at the outlet portion such that is operable to vaporize liquid at the outlet portion to create an aerosol.
2. The electronic smoking device of claim 1 , wherein the liquid reservoir is closed.
3. The electronic smoking device of claim 1 , wherein the liquid reservoir comprises at least one air inlet.
4. The electronic smoking device of claim 3 , wherein the at least one air inlet has a diameter allowing air to enter into the liquid reservoir and preventing the liquid to escape from the liquid reservoir.
5. The electronic smoking device of claim 1 , wherein at least a part of a casing of the liquid reservoir comprises a semi-permeable membrane allowing air to enter into the liquid reservoir and preventing the liquid to escape from the liquid reservoir.
6. The electronic smoking device of claim 1 , wherein the outlet portion comprises at a plurality of openings arranged circumferentially at a peripheral surface of the glass capillary tube.
7. The electronic smoking device of a claim 1 , wherein a heating wire of the atomizer is arranged in front of the outlet portion.
8. The electronic smoking device of claim 1 , wherein a heating wire of the atomizer is wound around a peripheral surface of the glass capillary tube at the outlet portion.
9. The electronic smoking device of claim 1 , wherein the glass capillary tube is detachable from the liquid reservoir.
10. The electronic smoking device of claim 1 , wherein the outlet portion comprises a second open end of the glass capillary tube.
11. The electronic smoking device of claim 1 , wherein a second open end of the glass capillary tube is arranged inside the liquid reservoir.
12. The electronic smoking device of claim 1 , comprising a plurality of glass capillary tubes having respective outlet portions, wherein a heating wire of the atomizer is wound around the plurality of glass capillary tubes at the respective outlet portions.
13. The electronic smoking device of claim 1 , wherein the glass capillary tube is inflexible.
14. A cartomizer operable to be connected to a power supply for an electronic smoking device comprising:
an elongated, hollow body having a mouthpiece opening in a first end and a coupling adapted to couple to a battery portion of an electronic smoking device in an opposite second end;
a liquid reservoir for accommodating a liquid;
a glass capillary tube;
wherein the glass capillary tube comprises a first open end arranged inside the liquid reservoir and an outlet portion, wherein the glass capillary tube is adapted to transport liquid from the first open end to the outlet portion by capillary force, and wherein the outlet portion comprises at least one opening in a peripheral surface of the glass capillary tube; and
wherein the outlet portion is arranged at the second end of the cartomizer such that an atomizer arranged in the battery portion is operable to vaporize liquid at the outlet portion to create an aerosol.
