<p>An assembly for evaporating a volatile material, the assembly comprising a device 1 and a refill 2 which are detachable from one another, wherein the device includes a perforating element (105, Fig 4b) which is configured to pierce the refill, and an induction coil 103; wherein the refill includes a susceptor 204 and a sealed pierceable reservoir 201 containing the volatile material; wherein, in use, the susceptor is arranged to heat the material when the refill is positioned in the device and when an alternating current is passed through the induction coil. The susceptor may be magnetic and the device may further comprise a control unit to control the operation of the induction coil and a feedback coil 104 configured to interact with a magnetic field generated by the induction coil and the control unit is configured to process an output from the feedback coil and from this output, vary a property of the alternating current passed through the induction coil. The invention further comprises a method of evaporating a volatile material.</p> |
