Induction Adapter Sleeve for Uniform HNB Stick Heating

The adapter sleeve acts as an intermediary component between the induction heating device and the HNB stick. It contains a susceptor that couples with the induction heating device to receive heating energy, which is then transferred to the HNB stick through thermal conduction. This mediator structure prevents direct contact between the heating device and HNB stick while enabling efficient and uniform heat transfer to the aerosol-generating substrate.

The adapter sleeve is designed to perform multiple functions simultaneously: it provides mechanical protection for the HNB stick, acts as a thermal conductor to distribute heat uniformly, serves as a structural interface between the heating device and HNB stick, and contains the susceptor for induction heating coupling. By consolidating these functions into a single component, the overall device complexity is minimized while achieving the desired protective and heating performance.

The adapter sleeve is pre-configured with structural features such as ridges, grooves, or tapered sections that guide the HNB stick into the correct position during insertion. These preliminary structural arrangements ensure that when the HNB stick is inserted, its heated portion is automatically aligned with the heating zone of the susceptor, eliminating the need for complex alignment mechanisms while maintaining high aerosol generation efficiency.
