Electronic smoking device and atomizer
It is provided an electronic smoking device ( 1 ) with a housing ( 2 ) including an atomizer ( 6 ) and a liquid reservoir ( 4 ). The atomizer ( 6 ) comprises a heating wire ( 8 ) and at least a first contact finger ( 9 ) adapted to supply a first electrical potential to the heating wire ( 8 ). The first contact finger ( 9 ) is adapted to contact the heating wire ( 8 ) at a plurality of different contact portions (P 1 , P 2 , P 3 , P 4 ) thereby altering the heating characteristics of the atomizer ( 6 ) which vaporizes liquid ( 5 ) supplied from the reservoir ( 4 ) to generate an aerosol ( 7 ).
1. An atomizer for an electronic smoking device being operable in use to generate an aerosol, comprising:
a heating wire, and
at least a first contact finger adapted to supply a first electrical potential to the heating wire,
wherein the first contact finger is adapted to contact the heating wire at a plurality of different contact portions, and
wherein the heating wire comprises a plurality of separate heating coils sequentially arranged along the heating wire, wherein each of the contact portions is formed between adjacent heating coils.
2. The atomizer of claim 1 , wherein the first contact finger is formed as a rotatable pin adapted to rotate around a first rotation axis.
3. The atomizer of claim 2 , wherein the plurality of different contact portions are equidistantly spaced apart from the first rotation axis.
4. The atomizer of claim 1 wherein each of the contact portions protrudes from a connecting line between adjacent heating coils.
5. The atomizer of claim 1 , wherein each of the contact portions is formed as a straight section of the heating wire.
6. The atomizer of claim 2 , wherein the plurality of contact portions are circularly arranged around the first rotation axis and equidistantly spaced apart from each other.
7. The atomizer of claim 1 , further comprising a second contact finger adapted to supply a second electrical potential to the heating wire that differs from the first electrical potential.
8. The atomizer of claim 7 , wherein the second contact finger is adapted to contact the heating wire at a second plurality of different contact portions, wherein a contact portion of the first contact finger differs from a contact portion of the second contact finger.
9. The atomizer of claim 7 , wherein the second contact finger is formed as a rotatable pin adapted to rotate around a second rotation axis.
10. The atomizer of claim 9 , wherein the plurality of different contact portions are equidistantly spaced apart from the second rotation axis.
11. The atomizer of claim 7 wherein the first contact finger is formed as a first rotatable pin adapted to rotate around a first rotation axis, the second contact finger is formed as a second rotatable pin adapted to rotate around a second rotation axis, and a distance between the first rotation axis and the second rotation axis is smaller than a distance between adjacent heating coils.
12. The atomizer of claim 1 having a flow path extending from the heating wire to a mouthpiece, with the heating wire in the flow path.
13. The atomizer of claim 1 further comprising a reservoir positioned to provide a liquid onto the heating wire.
14. An electronic smoking device comprising:
a mouthpiece,
an atomizer including a heating wire and at least a first contact finger adapted to supply a first electrical potential to the heating wire, wherein the first contact finger is adapted to separately contact the heating wire at each of a plurality of different contact portions, the heating wire comprises a plurality of separate heating coils sequentially arranged along the heating wire, and each of the contact portions is formed between adjacent heating coils,
a reservoir, wherein the atomizer is adapted to vaporize a liquid supplied from the reservoir to generate an aerosol, and
a housing accommodating the atomizer and the reservoir.
15. The electronic smoking device of claim 14 , wherein the housing is elongated and a longitudinal axis of the housing is parallel to a first rotation axis of the first contact finger.
