Abstract
A collector assembly is adapted for use in a fragrance diffusion system. The collector assembly incorporates a dual-thread collector base including an integrally-formed cartridge coupler and neck. The cartridge coupler has an internal screw thread designed for mating with a complementary external screw thread of a fragrance cartridge. The neck has an external screw thread which matches the internal screw thread of the cartridge coupler. An atomizing device including a flow nozzle is attached to the collector base and defines an internal air passage to an atomization chamber. An airblast through the internal passage of the nozzle creates a suction force drawing liquid fragrance from the cartridge through a vacuum tube and into the atomization chamber where the liquid fragrance is converted into droplets prior to discharging outwardly through a vapor port and into a vapor chamber inside the cartridge.
