Abstract
A smoke generator apparatus has a housing with an electrical pump mounted in the housing and connected to a fluid reservoir filled with a fluid for generating smoke. A coiled electical resistance heating tube is mounted in the housing and forms an electrical resistance in an electrical circuit. The coiled electrical resistance heating tube has a thin coating of an electrical insulating, thermal conducting material, such as a thin coating of boron nitride thereon which electrically isolates the coils of the coiled electrical resistance heating tube while conducting heat through the coils from the hot to the cold end of the coiled electrical resistance heating tube. The coiled electrical resistance heating tube has one end operatively connected to the pump and the other end forming an outlet for dispensing superheated vapors into the ambient air for condensation into smoke particles. A pair of thermostats is mounted at different positions on the coated coiled electrical resistance heating tube for sensing the temperature therein for controlling heater temperature and actuating the pump for pumping the fluid from the reservoir into the resistance heating tube for generating the smoke.
