Heater Device Component

A capsule for an electronic cigarette, the capsule having a first end configured to engage with an electronic cigarette device and a second end arranged as a mouthpiece portion having a vapour outlet, the capsule further comprising:

• a reservoir arranged to store a liquid to be vaporised;
• a heater unit housing a vaporising chamber and arranged to vaporise the liquid received from the reservoir to generate a vapour;
• and
• a vapour flow path extending between the vaporising chamber and the mouthpiece to allow the generated vapour to flow from the vaporising chamber to the mouthpiece;
• wherein the heater unit comprises a plurality of through-channels arranged to allow the generated vapour to flow from the vaporising chamber to the vapour flow path;
• and
• wherein the heater unit is arranged to heat the liquid through sidewalls of the plurality of through-channels, as the liquid is drawn through the through-channels, in order to generate the vapour.

An electronic cigarette comprising a main body and a capsule wherein the main body comprises a power supply unit, electrical circuitry, and a capsule seating configured to connect with the capsule, the capsule comprising:

• a first end configured to engage with the electronic cigarette device and a second end arranged as a mouthpiece portion having a vapour outlet, the capsule further comprising:
• a reservoir arranged to store a liquid to be vaporised;
• a heater unit housing a vaporising chamber and arranged to vaporise a liquid received from the reservoir and generate a vapour;
• and
• a vapour flow path extending between the vaporising chamber and the mouthpiece to allow the generated vapour to flow from the vaporising chamber to the mouthpiece;
• wherein the heater unit comprises a plurality of through-channels arranged to allow the generated vapour to flow from the vaporising chamber to the vapour flow path;
• and
• wherein the heater unit is arranged to heat the liquid through sidewalls of the plurality of through-channels, as the liquid is drawn through the through-channels, to generate the vapour.
