Abstract
A heater for heating an aerosol-forming substrate includes a plurality of elongate heating elements arranged in an elongate array. The elongate array has a support end with a first dimension, a heating end with a second dimension and a middle portion with a third dimension. The array is arranged to heat the substrate to form an aerosol. The third dimension is greater than the first dimension and greater than the second dimension. An electrically heated aerosol generating system can include the heater.
Claims16
An electrically heated aerosol generating system comprising:
- an aerosol-forming substrate;
- and
- a heater, the heater comprising a plurality of flexible, elongate heating elements arranged in an elongate array, each of the plurality of elongate heating elements having a support end with a first diameter, a second end with a second diameter and a middle portion with a third diameter, the array arranged at least partially inside of the aerosol-forming substrate so as to heat the aerosol-forming substrate to form an aerosol, wherein the third diameter is greater than the first diameter and greater than the second diameter.
An electrically heated aerosol generating system comprising:
- an aerosol-forming substrate;
- and
- a heater, the heater comprising a plurality of flexible, elongate heating elements arranged in an elongate array, each of the plurality of elongate heating elements having a support end with a first diameter, a second end with a second diameter and a middle portion with a third diameter, the array arranged at least partially inside of the aerosol-forming substrate so as to heat the aerosol-forming substrate to form an aerosol, wherein the third diameter is greater than the first diameter and greater than the second diameter,
- wherein the aerosol-forming substrate includes a cavity and the diameter of the middle portion of the array is larger than an inside diameter of the cavity, such that, when the plurality of heating elements is inserted into the cavity of the aerosol-forming substrate, the heating elements are pressed towards each other so as to exert a force on the substrate.
