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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The device according to claim 1, wherein the heater is positioned around a portion of an outer periphery of the compartment. ### Claim 3 (depends on 1) The device according to claim 1, wherein the heater comprises an induction coil. ### Claim 4 (depends on 1) The device according to claim 1, further comprising a rod-shaped portion of vapour forming substance in the compartment. ### Claim 5 (depends on 1) The device according to claim 1, further comprising a clip or a biased retainer member for retaining a portion of vapour forming substance on the device in use. ### Claim 6 (depends on 1) The device according to claim 1, further comprising an air inlet positioned to provide air substantially only into one of the regions of the compartment adjacent to the heater. ### Claim 7 (depends on 1) A system for heating a vapour forming substance comprising: the device according to claim 1; an inlet for allowing air to enter the compartment; a power supply for the heater; and a controller for controlling the power supply. ### Claim 8 (depends on 7) The system for heating a vapour forming substance according to claim 7, further comprising a portion of vapour forming substance positioned in the compartment and a mouthpiece extending out from the device. ### Claim 9 (depends on 1) A system for heating a vapour forming substance comprising: the device according to claim 1; an inlet for allowing air to enter the compartment; a power supply for the heater; and a controller for controlling the motor and the power supply, wherein the motor is configured for driving the driving mechanism for generating relative motion. ### Claim 10 (depends on 9) The system for heating a vapour forming substance according to claim 9, further comprising a portion of vapour forming substance positioned in the compartment and a mouthpiece extending out from the device. ### Claim 11 (depends on 1) A system for heating a vapour forming substance, comprising: the device according to claim 1; a portion of vapour forming substance positioned in the compartment; and a mouthpiece extending out from the device. ### Claim 12 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. ### Claim 13 (depends on 12) The device according to claim 12, wherein the electromagnetic shield is rotatable about the compartment. ### Claim 14 (depends on 12) The device according to claim 12, wherein the electromagnetic shield extends around three quarters of an outer periphery of the compartment. ### Claim 15 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 divider positioned within the compartment to define the plural regions. ### Claim 16 (depends on 15) The device according to claim 15, wherein the divider is constructed to prevent the passage of air therethrough. ### Claim 17 (depends on 15) The device according to claim 15, further comprising 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, wherein the divider is rotatable by the motor. ### Claim 18 (depends on 17) The device according to claim 17, wherein an end of the compartment defines an aperture to allow air to pass through the selectively heated region. ### Claim 19 (depends on 18) The device according to claim 18, wherein the aperture has a cross-section that corresponds to a cross-section of one of the regions defined by the divider. ### Claim 20 (depends on 15) The device according to claim 15, further comprising a rod-shaped portion of vapour forming substance in the compartment, wherein the divider is arranged to spread across a cross-sectional area which is smaller than that of the portion of vapour forming substance such that when the portion of vapour forming substance is inserted into the compartment, any wrapper on the outer periphery of the portion passes around the divider. ### Claim 21 (depends on 15) The device according to claim 15, further comprising a rod-shaped portion of vapour forming substance in the compartment, wherein the divider has a longitudinal length which is at least 50% of a length of the portion of vapour forming substance. ### Claim 22 (depends on 15) The device according to claim 15, wherein the divider comprises an electromagnetic shielding material.
