Abstract
It is provided an electronic smoking device (10) which comprises a liquid reservoir (34), a battery (18) and a heating element (28) adapted to atomize liquid of the liquid reservoir (34). The heating element (28) has a modified surface (50) that comprises a plurality of structures (51) adapted to provide a capillary force on liquid of the liquid reservoir (34) when applied onto the heating element (28).
Claims20
An electronic smoking device comprising:
- a liquid reservoir;
- a battery;
- a heating element adapted to atomize a liquid of the liquid reservoir, the heating element further adapted to be provided power by the battery;
- wherein
- the heating element has a modified surface which comprises a plurality of structures adapted to provide a capillary force on the liquid of the liquid reservoir when applied onto the heating element, wherein the plurality of structures include a fin, crack, furrow, trench, cubic structure, or trapezoidal structure.
A method for the manufacturing of a heating element for an electronic smoking device, the method comprising the steps of:
- providing a conductive material with a first terminal and a second terminal, respectively, for connection with a power source;
- treating at least a fraction of a surface of the conductive material mechanically or chemically or using an external power source;
- and providing the fraction of the surface with a plurality of structures adapted to provide a capillary force on liquid of a liquid reservoir when applied onto the heating element, wherein the plurality of structures include a fin, crack, furrow, trench, cubic structure, or trapezoidal structure.
