Abstract
An aerosol provision device includes at least one inductor coil for generating a varying magnetic field and a susceptor assembly arranged to receive aerosol generating material. The susceptor assembly is heatable by penetration with the varying magnetic field and includes a first portion defining an opening at one end of the susceptor assembly, where the opening has a first internal cross section. The susceptor assembly further includes a second portion adjacent to the first portion. The second portion has a second internal cross section that is less than the first internal cross section.
Claims18
An aerosol provision device comprising:
- at least one coil;
- and
- a unitary heater element in which heat is generated and arranged to receive aerosol generating material, wherein the unitary heater element comprises:
- a first portion defining an opening at one end of the unitary heater element, the opening having a first internal cross section, the first portion heatable by the at least one coil, and
- a second portion adjacent to the first portion, the second portion having a second internal cross section, wherein the first internal cross section is greater than the second internal cross section, and the second portion has a generally constant internal cross-section over the majority of the length of the section portion.
A method of manufacturing a heater assembly for an aerosol provision device, comprising:
- providing a heater assembly having a length and a generally constant internal cross section along the length;
- and
- increasing an internal cross section at one end of the heater assembly, such that the internal cross section at the one end is greater than the generally constant internal cross section adjacent the one end.
A unitary heater element in which heat is generated for an aerosol provision device, wherein the heater element is hollow to receive aerosol generating material, and wherein the heater element has a flared end, and wherein the unitary heater element comprises at least one portion having a generally constant internal cross-section over the majority of the length of the at least one portion.
