AI Technical Summary

Technical Problem

Existing aerosol delivery devices face constraints in magnetic field generating devices due to space, size, and power limitations, which affect the efficiency of inductive coupling between the magnetic field generating device and the susceptor, limiting the performance of aerosol generation.

Method used

The use of a conductive element with a secondary coil configuration, including non-helical portions and a conductive connector, allows for induced current measurement in the secondary coil, enabling a controller to adjust current characteristics for precise temperature control of the heating chamber, and the inclusion of an electromagnetic shield for improved magnetic field generation.

Benefits of technology

This configuration enhances temperature control and magnetic field efficiency, ensuring the aerosolizable material is heated within a predetermined range, improving the performance and consistency of aerosol production.

Abstract

To provide an inductor for use in an aerosol provision device.SOLUTION: The inductor includes an electrically conductive element and a secondary coil. The element includes an electrically conductive non-spiral first portion 601 coincident with a first plane, an electrically conductive non-spiral second portion 602 coincident with a second plane that is spaced from the first plane, and an electrically conductive connector 603 that electrically connects the first portion 601 to the second portion 602. The electrically conductive element is configured such that, when a varying electrical current is applied to the electrically conductive element, a corresponding varying electrical current is induced in the secondary coil.SELECTED DRAWING: Figure 6
