The heater unit includes a plurality of through-channels arranged to allow the generated vapour to flow from the vaporising chamber to the vapour flow path. ## Claims ### Claim 1 A heater device for an electronic cigarette comprising: a heater unit housing a vaporising chamber and arranged to vaporise a liquid received from a liquid reservoir to generate a vapour; and a vapour flow path extending from the vaporising chamber arranged to fluidly communicate with a mouthpiece of an electronic cigarette 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. ### Claim 2 (depends on 1) The heater device according to claim 1 wherein the through-channels form part of the vapour flow path. ### Claim 3 (depends on 1) The heater device according to claim 1 wherein the through-channels act as a filter arranged to filter the generated vapour as the generated vapour flows from the vaporising chamber to the vapour flow path. ### Claim 4 (depends on 1) The heater device according to claim 1 wherein all of the through-channels of the plurality of through-channels have the same diameter. ### Claim 5 (depends on 1) The heater device according to claim 1 wherein the heater unit comprises a first heating portion and a second heating portion, wherein: the first heating portion is arranged to vaporise the liquid received from the liquid reservoir to generate the vapour; the vaporising chamber is arranged between the first and second heating portions and arranged to receive the generated vapour from the first heating portion; and the second heating portion is arranged to receive the generated vapour from the vapour chamber and further arranged to heat the generated vapour. ### Claim 6 (depends on 5) The heater device according to claim 5 wherein the plurality of through-channels form part of the second heating portion. ### Claim 7 (depends on 5) The heater device according to claim 5 wherein the vapour flow path comprises a first vapour flow portion and a second vapour flow portion, wherein: the first vapour flow portion extends between the vaporising chamber and the second heating portion; and the second vapour flow portion extends from the second heating portion and is arranged to fluidly communicate with the mouthpiece. ### Claim 8 (depends on 7) The heater device according to claim 7 wherein the first vapour flow portion and the second vapour flow portion are substantially in line with each other such that the vapour flowing from the first vapour flow portion to the second vapour flow portion follows a substantially straight flow path having substantially linear flow. ### Claim 9 (depends on 7) The heater device according to claim 7 wherein the first vapour flow portion and the second vapour flow portion are offset from each other such that the vapour flowing from the first vapour flow portion to the second vapour flow portion changes direction as it flows between the first and second vapour flow portions. ### Claim 10 (depends on 9) The heater device according to claim 9 wherein the first and second vapour flow portions are arranged such that the vapour flow path has a U-shape. ### Claim 11 (depends on 9) The heater device according to claim 9 wherein the first and second vapour flow portions are arranged such that the vapour flow path has a zig-zag shape. ### Claim 12 (depends on 1) The heater device according to claim 1 further comprising an air inflow path extending between an air inlet and the heater unit for allowing air to enter into the heater unit. ### Claim 13 (depends on 12) The heater device according to claim 12 wherein the generated vapour is delivered to the second heating portion from the first heating portion under the action of air which has entered the air inlet and flowed along the airflow path. ### Claim 14 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. ### Claim 15 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.
