13. The vaporiser head according to claim 1 ,
wherein the electrically operable heating element is a microelectromechanical system (MEMS) and/or is silicon-based.
14. A liquid reservoir, comprising:
a tank housing,
wherein the tank housing is configured to be punctured by a liquid conducting cannula.
15. The liquid reservoir according to claim 14 ,
wherein the tank housing comprises a piercing seal.
16. The liquid reservoir according to claim 14 ,
wherein the liquid reservoir is made at least in part of plastics material and/or metal capable of being punctured by the liquid conducting cannula.
17. The liquid reservoir according to claim 14 , further comprising:
a locking device for locking an external component in place.
18. A consumption unit, comprising:
a vaporiser head according to claim 1 ; and
a liquid reservoir,
wherein the liquid reservoir comprises:
a tank housing,
wherein the tank housing is configured to be punctured by a liquid conducting cannula,
wherein the vaporiser head is configured to pierce the liquid reservoir via the liquid conducting cannula to produce a ready-to-use state of the consumption unit.
19. The consumption unit according to claim 18 , further comprising:
a mouthpiece.
20. The consumption unit according to claim 19 ,
wherein the support plate of the vaporiser head is attached to the mouthpiece.
21. The consumption unit according to claim 19 ,
wherein in the ready-to-use state of the consumption unit, the liquid conducting cannula is sunk into the mouthpiece.
22. The consumption unit according to claim 18 ,
wherein in the ready-to-use state of the consumption unit, the support plate is aligned with the tank housing of the liquid reservoir.
23. The consumption unit according to claim 18 ,
