Electronic smoking device with liquid reservoir/wick portion
The invention relates to a liquid reservoir/wick portion and to an electronic smoking device comprising a liquid reservoir/wick portion. In order to avoid different liquids undesirably mixing in a wick of the electronic smoking device, the liquid reservoir/wick portion comprises a wick. The wick comprising a liquid receiving side coupled to a liquid storage volume of the liquid reservoir/wick portion, and a liquid supply side coupled to an atomizing element of the electronic smoking device.
1. An electronic smoking device comprising:
a liquid reservoir/wick portion including a liquid storage volume and a wick configured and arranged for supplying the liquid from the liquid storage volume to an atomizing element when the liquid reservoir/wick portion is coupled to the atomizing element; and
the atomizing element configured and arranged for atomizing liquid;
wherein the wick includes a liquid receiving side coupled to the liquid storage volume, and a liquid supply side coupled to the atomizing element when the liquid reservoir/wick portion is coupled to the atomizing element;
wherein the liquid reservoir/wick portion and the atomizing element are further configured and arranged to be coupled to and separated from one another;
wherein the wick has one or more of the following characteristics: a hollow cylindrical shape or an annular shape.
2. The electronic smoking device of claim 1 , wherein the wick includes a central opening in fluid communication with a central passage of the liquid reservoir/wick portion, the central passage extending away from the atomizing element and towards an air inhalation port of the electronic smoking device.
3. The electronic smoking device of claim 1 , wherein the wick is attached to a base of the liquid storage volume, the base having liquid conduits configured and arranged to supply liquid to the wick.
4. The electronic smoking device of claim 2 , wherein the liquid receiving side is in contact with a front face of the liquid reservoir/wick portion, the front face facing the atomizing element and configured and arranged to be permeable for liquid.
5. The electronic smoking device according to claim 4 , wherein the front face encircles the central passage.
6. The electronic smoking device of claim 1 , wherein the atomizing element is in direct contact with the liquid supply side.
7. The electronic smoking device of claim 1 , wherein the liquid supply side has an arced shape and at least partially encompasses the atomizing element.
8. The electronic smoking device of claim 1 , wherein an envelope of the atomizing element is essentially cone-shaped.
9. The electronic smoking device of claim 8 , wherein the atomizing element is a heating coil with an inner wire section, around which windings with an increasing diameter are wound.
10. The electronic smoking device of claim 1 , wherein the atomizing element is a heating coil, whose windings have a constant diameter.
11. The electronic smoking device of claim 1 , wherein the atomizing element is a torus-shaped heating coil or comprises a spirally formed heating wire.
12. The electronic smoking device of claim 1 , wherein the liquid reservoir/wick portion is configured to be replaceable.
13. A liquid reservoir/wick portion for an electronic smoking device, comprising a liquid storage volume and a wick, wherein the wick comprises a liquid receiving side that faces the liquid storage volume, and a liquid supply side opposite of the liquid receiving side, the liquid supply side facing away from the liquid storage volume; and
wherein the liquid reservoir/wick portion is configured and arranged to be detachably connected to an atomizing element within the electronic smoking device.
14. The liquid reservoir/wick portion of claim 13 , wherein the wick has one or more of the following characteristics: a hollow cylindrical shape or an annular shape.
15. The liquid reservoir/wick portion of claim 13 , wherein the wick is attached to a base of the liquid storage volume, the base including liquid conduits configured and arranged to supply liquid to the wick.
16. The liquid reservoir/wick portion of claim 13 , wherein the wick has a central opening in fluid communication with a central passage of the liquid reservoir/wick portion, the central passage extending away from an atomizing element.
17. The liquid reservoir/wick portion of claim 13 , wherein the liquid storage volume is configured and arranged to store a liquid, and the wick is configured and arranged for supplying the liquid from the liquid storage volume to an atomizing element of the electronic smoking device.
