Fan diffuser assembly and method

A fan diffuser assembly, comprising:

• an inverted frustoconical base having a large diameter end and an opposing small diameter end, and a plurality of spaced apart radial webs extending longitudinally between said large diameter end and said small diameter end;
• a housing located over said frustoconical base and carried by a respective support structure at each of said radial webs, and said housing comprising an intake end, side walls and an output end, and said intake end being longitudinally spaced apart from said large diameter end of said frustoconical base and cooperating with said side walls of said housing to define an air intake of said fan diffuser assembly;
• an electric fan located within said housing and mounted adjacent said small diameter end of said frustoconical base, whereby operation of said fan generates a 360-degree laminar airflow through said air intake, along a tapering exterior of said frustoconical base, through said housing and outwardly through said output end into a surrounding environment;
• and
• an exchangeable fragrance cartridge located inside said housing between said electric fan and said output end of said housing.

A fan diffuser assembly, comprising:

• an inverted frustoconical base having a large diameter end and an opposing small diameter end, and a plurality of spaced apart radial webs extending longitudinally between said large diameter end and said small diameter end, and wherein said large diameter end is greater than 3 times a diameter of said small diameter end;
• a housing located over said frustoconical base and carried by a respective support structure at each of said radial webs, and said housing comprising an intake end, side walls and an output end, and said intake end being longitudinally spaced apart from said large diameter end of said frustoconical base and cooperating with said side walls of said housing to define an air intake of said fan diffuser assembly;
• an electric fan located within said housing and mounted adjacent said small diameter end of said frustoconical base, whereby operation of said fan generates a 360-degree laminar airflow through said air intake, along a tapering exterior of said frustoconical base, through said housing and outwardly through said output end into a surrounding environment;
• and
• an ionization device located inside said housing between said electric fan and said output end of said housing.
