Claim of US Patent No. 10,362,803

1. An electronic vaporizer device for simulating smoking, the device comprising:at least one aerosol generating structure, comprised of:
a first heating element;
a wick configured to supply a liquid to the first heating element, the first heating element aerosolizing the liquid into an aerosol;
an air channel configured to carry the aerosol generated at the first heating element away from the first heating element;
at least one second heating structure comprised of:
a second heating element;
the second heating element being downstream relative to the first heating element to apply heat to the aerosol,
wherein the at least one second heating structure does not receive the liquid from the wick;
a connector; and
a controller that is to be removably coupled to, and separable from the aerosol generating structure by the connector, the controller being further connected to a power source providing electrical power, the controller having at least two regulated outputs which can supply the electrical power to the first heating element and the second heating element concurrently with independent control of each output, wherein the controller independently controls at least the output that supplies electrical power to the second heating element based on one or more relationships between a measured resistance of the second heating element during operation, and a known resistance of the second heating element at one or more specific temperatures;
wherein the at least one aerosol generating structure forms the aerosol having a particle size distribution in a controllable manner; and wherein the at least one second heating structure is downstream of the first heating element, the second heating element applying additional heat to the aerosol to at least change the particle size distribution within the aerosol to generate an output aerosol in a controllable manner.
