US Patent 8975764 Electronic cigarette with integrated charging mechanism

A power generating electronic cigarette includes a partially hollowed body having an enclosed distal end, and a filter cartridge attached at a proximal end of the body. The cigarette operates using power stored within a portable power storage media integrated within the body. A power generating subassembly is located within the hollowed body, wherein the power generating subassembly generates an electrical current to charge the power storage media. The power generating subassembly utilizes motion of a magnet in proximity of a coil to generate an electrical current within the coil. The current can be converted into stored electrical power. Motion of the magnet can result from shaking or rolling the electronic cigarette. Alternately, the magnet can be rotated by an airflow driven device operated by airflow applied to the cigarette.
