AEROSOL-GENERATING DEVICE AND SYSTEM

摘要

The present disclosure relates to an electrical system comprising a primary device and secondary device. The primary device comprises: a source of electrical power; a cavity configured to receive the secondary device; at least one electrical contact within the cavity configured to contact a corresponding contact on the secondary device when the secondary device is in the cavity, the at least one electrical contact being electrically connected to the source of electrical power; and at least one data contact configured to transfer data between the primary device and the secondary device; wherein, the secondary device is keyed to the cavity of the primary device. The secondary device may be an aerosol- generating device, and the primary device may be a charging device for charging the aerosol-generating device. The secondary device may have a polygonal cross-sectional shape.
