An induction heating assembly for a vapour generating device includes an induction coil and a heating compartment arranged to receive an induction heatable cartridge. A first electromagnetic shield layer is arranged outward of the induction coil and a second electromagnetic shield layer is arranged outward of the first electromagnetic shield layer. The first and second electromagnetic shield layers differ in one or both of their electrical conductivity and their magnetic permeability.

Induction heating assembly for a vapour generating device

A method is provided for operating an electronic vapour inhaler comprising an induction heating arrangement, the induction heating arrangement comprising an induction coil for generating an alternating electromagnetic field to heat an induction heatable element and thereby heat a non-liquid flavour-release medium. The method comprises intermittently energising the induction coil to generate an intermittent alternating electromagnetic field which provides pulsed heating and cooling of the induction heatable element.

Method for operating an electronic vapour inhaler

An electronic vapour inhaler includes a chamber configured so that a user can place a cartridge into said chamber, an induction coil arranged to extend around the chamber, a temperature sensor configured to measure a temperature inside the chamber, and a control arrangement arranged to control operation of the induction coil based on the temperature measured by the temperature sensor to maintain a predetermined temperature inside the chamber.

Electronic vapour inhalers with temperature control

A cartridge for an electronic vapour inhaler is provided and includes an elongate induction heatable element and a flavour-release medium adhered to a surface of the elongate induction heatable element. The induction heatable element can include a tube having a wall with inner and outer wall surfaces and the flavour-release medium can be adhered to the outer or inner wall surface.

Electronic vapour inhaler including a control arrangement that recognizes an inserted cartridge or capsule

An induction heating assembly for a vapour generating device includes an induction coil and a low-pass filter positioned adjacent to the induction coil. The low-pass filter is electrically connected to the induction coil to act as a low-pass filter for the induction coil and is shaped to extend substantially across at least one side of the induction coil to provide an electromagnetic shield for the induction coil.

An induction heating assembly for a vapour generating device comprises includes an induction coil and a heating compartment arranged to receive an induction heatable cartridge. A first electromagnetic shield layer is arranged outward of the induction coil and a second electromagnetic shield layer is arranged outward of the first electromagnetic shield layer. The first and second electromagnetic shield layers differ in one or both of their electrical conductivity and their magnetic permeability.

A container sealing apparatuscomprises an electrically conductive linearly displaceable cutting memberoperable to cut a portionof sealing material from a weband an independently linearly displaceable transfer membercomprising an electrically insulating material and extendible relative to the cutting memberto transfer the cut portionof sealing material to an open top of a containerto be sealed. An induction coilproduces an induction fieldfor heating the cut portionof sealing material, either directly or indirectly, by induction heating to seal the cut portionof sealing material to the open top of the container. The linearly displaceable transfer memberholds the cut portionof sealing material against the open top of the containerduring induction heating. A field concentratoris provided to concentrate the induction fieldin a desired region away from the linearly displaceable electrically conductive cutting memberand other electrically conductive component parts of the apparatusto optimize the induction heating of the cut portionof sealing material.
