  • induction heating the vapour generating device employs an electromagnetic field generator and an induction coil to generate an alternating electromagnetic field that couples with, and inductively heats, an inductively heatable susceptor. Heat from the inductively heatable susceptor is transferred to the vapour generating substrate to release one or more volatile components and generate a vapour.
  • the vapour generating substrate is a vapour generating liquid (or so called “e-liquid”), for example containing one or more of nicotine, propylene glycol, glycerine and flavourings.
  • the vapour generating liquid can be transferred from a liquid store by a liquid transfer element, such as a wick, and is
  • vapour generating liquid, liquid transfer element and inductively heatable susceptor can be provided together in a replaceable cartridge (cartomizer) that is configured for use with the vapour generating device.
  • induction heating in vapour generating devices Whilst the use of induction heating in vapour generating devices is efficient, currently available inductively heated vapour generating devices can suffer from a number of drawbacks which the present disclosure seeks to address.
  • a cartridge for a vapour generating device comprising: a liquid store for containing a vapour generating liquid; a vaporization device including a heating element comprising at least one substantially cylindrical inductively heatable susceptor positioned beneath the liquid store and arranged coaxially with respect to a central longitudinal axis of the cartridge; at least one channel or opening which connects the liquid store to the vaporization device; and a porous liquid transfer element positioned adjacent to the at least one channel or opening and arranged to hold and transfer vapour generating liquid from the at least one channel or opening to the vaporization device by capillary action; wherein the at least one substantially cylindrical inductively heatable susceptor is arranged in thermal proximity to the porous liquid transfer element to heat and vaporize the vapour generating liquid held and transferred to the vaporization device by the porous liquid transfer element.
  • the cartridge is intended for use with a vapour generating device that is configured to heat the vapour generating liquid to volatise at least one component of the vapour generating liquid and thereby generate a vapour which cools and condenses to form an aerosol for inhalation by a user of the vapour generating device.
  • a vapour generating system comprising a vapour generating device and a cartridge according to the first aspect releasably connected to the vapour generating device.
  • vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapour can be condensed to a liquid by increasing its pressure without reducing the temperature
  • aerosol is a suspension of fine solid particles or liquid droplets, in air or another gas.
  • an inductively heatable susceptor having a substantially cylindrical shape By using an inductively heatable susceptor having a substantially cylindrical shape and by positioning the substantially cylindrical inductively heatable susceptor beneath the liquid store, a strong electromagnetic coupling is achieved with the generated electromagnetic field, in particular because the inductively heatable susceptor is positioned in the region of highest electromagnetic field concentration.
  • This in turn provides for rapid and uniform heating of the inductively heatable susceptor to a desired temperature and, thus, rapid and uniform heating of the vapour generating liquid, thereby ensuring instant vaporization of the vapour generating liquid and ensuring reliable vapour generation.
  • the energy efficiency of the vapour generating device is also improved.
  • the coaxial arrangement of the inductively heatable susceptor with respect to the central longitudinal axis of the cartridge may also contribute to these advantageous effects because an optimum positioning of the inductively heatable susceptor with respect to the generated electromagnetic field (and hence a strong electromagnetic coupling) can be assured when the cartridge is connected to a vapour generating device.
  • the coaxial arrangement may also facilitate manufacture and assembly of the cartridge because the inductively heatable susceptor can be easily positioned coaxially with respect to the central longitudinal axis of the cartridge.
  • the at least one channel or opening provides a reliable and efficient supply of the vapour generating liquid from the liquid store to the porous liquid transfer element.
  • P51119WO This further contributes to reliable vapour generation by ensuring that a sufficient amount of vapour generating liquid is always available to be held and transferred by the porous liquid transfer element to the vaporization device, and more particularly the inductively heatable susceptor.
  • the porous liquid transfer element may be substantially cylindrical.
  • the porous liquid transfer element may be toroidal.
  • the at least one substantially cylindrical inductively heatable susceptor may have an axial length which is less than an axial length of an outer surface of the porous liquid transfer element.
  • the term “axial length” means a length in the direction of the longitudinal axis of the cartridge.
  • the at least one substantially cylindrical inductively heatable susceptor may extend around an outer surface of the porous liquid transfer element, and in particular may extend around a radially outer surface of the porous liquid transfer element.
  • the at least one substantially cylindrical inductively heatable susceptor is positioned outwardly, e.g., radially outwardly, of the porous liquid transfer element. This further ensures that the inductively heatable susceptor is positioned in the region of highest electromagnetic field concentration and, thus, further helps to ensure that a strong electromagnetic coupling is achieved with the generated electromagnetic field.
  • the at least one substantially cylindrical inductively heatable susceptor may fully surround the outer surface of the porous liquid transfer element. By fully surrounding
  • the at least one substantially cylindrical inductively heatable susceptor is desirably dimensioned such that uniform heat distribution is ensured over its surface area. This further ensures that an efficient and uniform transfer of heat, e.g., by conduction, from the substantially cylindrical inductively heatable susceptor to the porous liquid transfer element is achieved and that “hot spots” and “cold spots” are avoided.
  • a uniform transfer of heat from the inductively heatable susceptor to the porous liquid transfer element results in instantaneous vaporisation of the vapour generating liquid held and transferred by the porous liquid transfer element and avoids a build-up of vapour generating liquid which can cause over-saturation of parts of the porous liquid transfer element.
  • An over-saturated porous liquid transfer element can lead to projections of vapour generating liquid spitting from the porous liquid transfer element when heated by the inductively heatable susceptor. These liquid projections can be unpleasant when a user inhales the generated vapour.
  • the at least one substantially cylindrical inductively heatable susceptor may include an inner surface that contacts the outer surface of the porous liquid transfer element. With this arrangement, there is no gap between the outer surface of the porous liquid transfer element and the inner surface of the substantially cylindrical inductively heatable susceptor. Thus, heat can be readily conducted from the inductively heatable susceptor to the porous liquid transfer element thereby improving vapour generation and energy efficiency.
