Abstract

An aerosol delivery device is provided that includes a cartridge coupled with a control body. The cartridge is equipped with a heating element, an authentication device and a second switching circuit. The control body includes a first switching circuit and is configured to exchange authentication signals with the authentication device to authenticate the cartridge for use with the control body and, only in instances in which the cartridge is authenticated, direct power to the heating element. The control body and the cartridge include respectively a two-wire electrical connector and a corresponding two-wire electrical connector coupled with one another, and across which the authentication signals are exchanged and the power is directed. The first switching circuit is coupled with the second switching circuit to form switching circuitry configured to manage the authentication signals and the power across the two-wire electrical connector.

Dependent claims

An aerosol delivery device comprising:

a cartridge that is equipped with an authentication device and contains an aerosol precursor composition;
and
a control body coupled with the cartridge and including a control component configured to exchange authentication signals with the authentication device to authenticate the cartridge for use with the control body, and only in instances in which the cartridge is authenticated, control the aerosol delivery device to vaporize components of the aerosol precursor composition,
wherein the control body and the cartridge each include a pair of electrical connectors, the pair of electrical connectors of the cartridge configured to be coupled with the pair of electrical connectors of the control body to form a connection therebetween, wherein authentication signals are exchanged and the power is directed across the connection, and
wherein the aerosol delivery device further comprises:
a first switching circuit in the control body coupled to and between the control component and the pair of electrical connectors of the control body;
and
a second switching circuit in the cartridge coupled to and between the authentication device and the pair of electrical connectors of the cartridge;
wherein the first switching circuit and second switching circuit are configured to manage the authentication signals and the power across the connection.
