Abstract
A device for heating a vapour forming substance includes a compartment for receiving a vapour forming substance. The compartment is divided into plural regions. A heater is provided for heating a vapour forming substance in the compartment in use to generate vapour therefrom. The device further includes means for controlling the heater such that a region adjacent to the heater can be selectively heated and so that vapour from that selectively heated region passes out from the device during operation of the heater. The heater extends in the longitudinal direction of the compartment.
Claims22
A device for heating a vapour forming substance, the device comprising:
- a compartment for receiving the vapour forming substance in use, the compartment extending along a longitudinal direction and being divided into plural regions;
- a heater for heating a vapour forming substance in the compartment in use to generate vapour therefrom, wherein the heater extends in the longitudinal direction of the compartment;
- a controller for controlling the heater such that a region of the plural regions that is adjacent to the heater can be selectively heated and so that vapour from that selectively heated region passes out from the device during operation of the heater;
- and
- a driving mechanism or a motor for generating relative motion between the heater and the regions such that one of the regions can be placed adjacent to the heater to be selectively heated and so that vapour from that selectively heated region passes out from the device during operation of the heater.
A device for heating a vapour forming substance, the device comprising:
- a compartment for receiving the vapour forming substance in use, the compartment extending along a longitudinal direction and being divided into plural regions;
- a heater for heating a vapour forming substance in the compartment in use to generate vapour therefrom, wherein the heater extends in the longitudinal direction of the compartment, wherein the heater comprises an induction coil;
- a controller for controlling the heater such that a region of the plural regions that is adjacent to the heater can be selectively heated and so that vapour from that selectively heated region passes out from the device during operation of the heater;
- and
- an electromagnetic shield positioned between the induction coil and the compartment, the electromagnetic shield being arranged to define a gap through which electromagnetic radiation can pass from the induction coil to the compartment in use.

- a compartment for receiving the vapour forming substance in use, the compartment extending along a longitudinal direction and being divided into plural regions;
- a heater for heating a vapour forming substance in the compartment in use to generate vapour therefrom, wherein the heater extends in the longitudinal direction of the compartment;
- a controller for controlling the heater such that a region of the plural regions that is adjacent to the heater can be selectively heated and so that vapour from that selectively heated region passes out from the device during operation of the heater;
- and
- a divider positioned within the compartment to define the plural regions.
