Problems solved by technology

However, such conventional coils may not always allow precise control of the temperature produced by the susceptor when the susceptor is heated inductively
Specifically, when using such conventional coils, it may be difficult to obtain a uniform temperature from the susceptor

Embodiment Construction

[0078] figure 1 A schematic diagram of an aerosol generating system 10 according to a first embodiment of the invention is shown in an unassembled state. The system includes an aerosol-generating article 20 and an aerosol-generating device 100 . The aerosol-generating article 20 includes four elements. These elements are: aerosol generating matrix 22 , hollow tubular support element 24 , aerosol cooling element 26 and filter section 28 . These four elements are arranged in sequence and in coaxial alignment, and assembled from rolling paper (not shown) to form a rod. The strip has an oral end defined by the filter section 28 that the user inserts into his or her mouth during use and a distal end defined by the aerosol-generating substrate 22 that is located on the opposite side of the strip from the oral end. at one end. Elements located between the oral end and the distal end may be described as upstream of the oral end, or alternatively downstream of the distal end 8 .

Abstract

An aerosol-generating device (10) comprises a housing (120) defining a chamber (111) for receiving at least one susceptor (130) and at least one aerosol-forming substrate (22). The chamber has a length along its longitudinal axis extending from a first end of the chamber to a second end of the chamber. An inductor coil (140) is provided within the housing, disposed around the chamber, and extendsalong at least a portion of the length of the chamber. The inductor coil comprises a first portion (141) disposed closest to the first end of the chamber, a second portion (142) disposed closest to the second end of the chamber, and a third portion (143) disposed between the first and second portions. The number of turns per unit length in the third portion of the coil is less than the number of turns per unit length in one or both of the first and second portions of the coil, and / or the cross sectional area of the coil in the third portion of the coil is less than the cross sectional area ofthe coil in one or both of the first and second portions of the coil.

Description

technical field [0001] The invention relates to an aerosol generating device. In particular, the present invention relates to an aerosol-generating device having an induction heater for heating an aerosol-generating article using a susceptor. The invention also relates to an aerosol generating system comprising the combination of such an aerosol generating device and an aerosol generating article or cartridge for use with the aerosol generating device. Background technique [0002] A number of electrokinetic aerosol-generating systems have been proposed in the art in which an aerosol-generating device with an electric heater is used to heat an aerosol-forming substrate, such as a tobacco filter segment. Typically, the aerosol-generating substrate is provided as part of an aerosol-generating article which is inserted into a chamber or cavity of the aerosol-generating device. In some known systems, in order to heat the aerosol-forming substrate to a temperature capable of re...
