Abstract: A cartridge for an electronic cigarette comprises: a liquid store arranged to contain a liquid to be vaporised; a vaporization chamber having at least one opening arranged to connect the vaporization chamber to the liquid store; a vaporising unit; and a pair of electric terminals connected to the heating element. The vaporising unit comprises: a fluid transfer element arranged to transfer liquid between the liquid store and the vaporization chamber; and a heating element arranged inside the vaporization chamber and arranged to heat a liquid transferred to the vaporization chamber by the fluid transfer element. The pair of electric terminals comprise a first connection plate and a second connection plate which are connected to a first end and a second end of the heating element, respectively, and the first and the second connection plates are arranged on a first side of the vaporization chamber.

Abstract: A cartridge for an electronic cigarette includes a liquid store arranged to contain a liquid to be vaporized; a vaporization chamber having at least one opening which connects the vaporization chamber to the liquid store; a fluid transfer element held within the opening and extending between the liquid store and vaporization chamber, the fluid transfer element arranged to transfer liquid between the liquid store and vaporization chamber by capillary action; a heating element positioned within the vaporization chamber and arranged to heat a liquid transferred to the vaporization chamber by the fluid transfer element; wherein the cartridge includes an upper housing portion and a lower housing portion which are configured to connect together around the fluid transfer element to form the liquid store, the vaporization chamber and the at least one opening. This provides an improved seal around the fluid transfer element to minimize leakage into the vaporization chamber.

Abstract: An induction heating assembly for an aerosol generating device includes an induction coil for generating an electromagnetic field, and an inductively heatable susceptor having a first part and a second part which include the same susceptor material. The first part is positioned with respect to the induction coil so that it is inductively heated by the electromagnetic field and the second part is positioned with respect to the induction coil so that it is not inductively heated by the electromagnetic field. The induction heating assembly further includes a temperature sensor in contact with the second part of the inductively heatable susceptor.

Abstract: A cartridge for an electronic cigarette is configured to thermically connect to a base part having at least one heating element. The cartridge includes: a liquid store including a liquid outlet; a vaporization chamber in communication with the liquid store via the liquid outlet; a sorption member in the vaporization chamber for absorbing liquid transferred to the vaporization chamber via the liquid outlet; and a heat transfer unit configured, when the cartridge is thermically connected to the base part, to transfer heat from the heating element to the sorption member to vaporize liquid absorbed by the sorption member. The sorption member and the heat transfer unit are only in partial contact in contact zones.

Abstract: An electronic cigarette includes a power supply portion having a heater and a replaceable cartridge having a liquid store. The power supply portion has a fluid transfer element with an elongated shape including a first wicking part extending outwardly from the power supply portion as a free end, and a second wicking part configured to deliver liquid to the heater for vaporization. The power supply portion has a seating configured to fixedly attach to the second wicking part. The first wicking part is configured to extend into the liquid store when the power supply portion is connected to the cartridge. The replaceable cartridge is removably coupled to the power supply portion such that the first wicking part can be engaged and disengaged from the liquid store and, when disengaged, the fluid transfer element is a part of the power supply portion 3.

Abstract: A vaporiser for an electronic cigarette has a fluid transfer element and a heater. The fluid transfer element is compressible and configured to transfer a portion of liquid from a liquid store to the heater. The contact surface of the fluid transfer element is configured to move relative to the heater such that when the contact surface of the fluid transfer element is compressed liquid is releasable from the fluid transfer element and adsorbable on the heater.

Abstract: A fluid transfer component is configured to establish a fluidic connection between a liquid store and a heater in an electronic cigarette. The fluid transfer component includes a liquid uptake member configured to connect with a housing of the liquid store, a chamber configured to receive liquid from the liquid store by the liquid uptake member, and a fluid transfer element including a compressible wick configured to transport liquid from the chamber to the proximity of the heater by capillary action and a flexible contact surface configured to deform in the axial direction of the fluid transfer component, wherein the flexible contact surface is configured to release liquid from the compressible wick for transfer to the heater when the fluid transfer element is compressed.

Abstract: An electronic cigarette includes a power supply portion and a replaceable cartridge. The replaceable cartridge has a fluid transfer element with a first wicking part configured to extend into a liquid store in the cartridge and a second wicking part configured to extend outwardly in a direction away from the liquid store. The fluid transfer element is configured to fluidically couple the liquid store to a heater in the power supply portion. The replaceable cartridge is removably coupled to the power supply portion such that the second wicking part can be engaged and disengaged from the heater and, when disengaged, the fluid transfer element is a part of the cartridge.
