A vaporiser insert for an electronic cigarette product comprises at least one electrical vaporiser for vaporising fluid supplied to the vaporiser and for supplying the vaporised fluid to an airflow, a main part having a lateral face which surrounds an airflow duct through which the airflow can flow, at least one fluid opening for supplying vaporisable fluid from the outside into the vaporiser insert and to the vaporiser being arranged on the lateral face of the main part. The vaporiser insert comprises a support for retaining the vaporiser, and the support comprises a passage opening that corresponds to the fluid opening in order to supply fluid to the vaporiser.

The present disclosure provides an air heater. The air heater comprises: a direct heat generating portion configured to be heated by an electric current supplied from outside; an indirect heat generating portion configured to be heated by conductive heat, which is supplied by physical contact with the heated direct heat generating portion, and configured to heat air coming in through an inlet opening formed on one side while the air is passing through an outlet opening formed on the other side; and a housing made of an insulating material that provides a space where the direct heat generating portion and the indirect heat generating portion are placed, and that comprises an air inlet on one side through which the air is drawn in from outside and an air vent on the other side through which the air is released.

A heat conductor and a heated media line having an inner tubular fluid line and at least one heat conductor arranged on the periphery thereof. The heat conductor is formed by a braid made of twisted individual wires and, in particular, an outer protective sheath surrounding the heat conductor and the fluid line. The braid is formed by at least six individual wires surrounding a support element, of which at least one individual wire is made of a copper-nickel (CuNi) alloy, and the remaining individual wires are produced from copper (Cu) or from a nickel-chromium (NiCr) alloy. All of the individual wires have the same diameter.

A vaporizer includes an atomizer, a vaporizer body, and a heating portion. The heating portion includes an inner heater block and an inner heater. An inner tube is made of a heat-resistant glass and has an outer diameter smaller than an inner diameter of the hollow vaporizer body. The inner heater block includes division pieces obtained by dividing the inner heater block along a center axis thereof and an elastic material. The elastic material is disposed between the division pieces and acts so as to press and urge the division pieces in separation directions and press them against an inner peripheral surface of the inner tube. The inner heater is embedded in each division piece.

An IR (infrared) radiation source includes a sealed cavity structure enclosing a vacuum chamber having a low atmospheric pressure, wherein the sealed cavity structure includes a thermally and electrically insulating material for enclosing the vacuum chamber, heating filaments extending in the vacuum chamber between opposing electrode regions at opposing wall regions of the vacuum chamber, wherein the heating filaments are electrically connected in parallel, and wherein the heating filaments and the electrode regions have a highly electrically conductive material, and an optical isolation structure adjacent to the vacuum chamber for optically confining the IR radiation and providing a predominant propagation direction of the IR radiation.
