Abstract: An aerosol provision device is provided. The device defines a longitudinal axis, and comprises a first coil and a second coil. The first coil is configured to heat a first section of a heater component, the heater component being configured to heat aerosol generating material to generate an aerosol. The second coil is configured to heat a second section of the heater component. The first coil has a first length along the longitudinal axis and the second coil has a second length along the longitudinal axis, the first length being shorter than the second length. The first coil is adjacent the second coil in a direction along the longitudinal axis. In use, the aerosol is drawn along a flow path of the device towards a proximal end of the device, and the first coil is arranged closer to the proximal end of the device than the second coil.

Abstract: Various configurations of heater components for aerosol provision devices are disclosed. One heater component is configured to receive aerosol generating material and has a longitudinal axis. The heater component has a first length along the longitudinal axis, the aerosol generating material has a second length along the longitudinal axis, and a ratio of the first length to the second length is between about 1.03 and about 1.25. Another heater component has a mass of between about 0.1g and about 1g. A further heater component comprises an alloy comprising at least 99 wt % Iron. A yet further heater component comprises carbon steel. A still further heater component defines a longitudinal axis and has a wall thickness, measured in a direction perpendicular to the longitudinal axis, of between about 0.025 mm and about 2 mm.

Abstract: A support for a heater component of an aerosol provision device defines an axis and is configured to engage an end of the heater component to hold the heater component substantially parallel to the axis at a predetermined distance from a coil. The support defines a channel to receive a wire of a temperature sensor, and the channel defines an opening into a space between the heater component and the coil. An aerosol provision device is also described which comprises: a heater component configured to heat aerosol generating material; a first support, wherein the first support defines an axis and is configured to engage a first end of the heater component; a second support, wherein the second support is configured to engage a second end of the heater component; and at least one coil configured to heat the heater component. The first and second supports hold the heater component substantially parallel to the axis at a predetermined distance from the at least one coil.

Abstract: An aerosol provision device is provided. The device comprises a receptacle configured to receive aerosol generating material, wherein the aerosol generating material is heatable by a susceptor. The device further comprises an inductor coil extending around the receptacle, wherein the inductor coil is configured to generate a varying magnetic field for heating the susceptor. The device further comprises a magnetic shield member extending at least partially around the inductor coil.

Abstract: Provided herein is a heat-not-burn article including an aerosol generating medium and a filter. The filter contains one or more crushable capsules. In use, the aerosol generating medium is heated without being combusted, and the capsule is exposed to a temperature of about 30 to 100° C. During the exposure the structural integrity of the capsule is not compromised such that the capsule can be crushed by the user before, during or after heating.
