1. An aerosol generator comprising:

  • (a) an air blower having an air discharge side;

    (b) a nozzle defining a path of travel for an air stream from its air receiving side to its discharge side and thence, into the ambient air, said nozzle being adapted to entrain liquid into said air stream for producing droplets dispensed in said air as it is discharged from said nozzle;

    (c) a robe for supplying liquid to said nozzle for being entrained in said air stream;

    (d) a duct connected between the discharge side of said blower and said air receiving side of said nozzle for directing air discharged from said discharge side of said blower to said air receiving side of said nozzle;

    (e) a valve communicating with said duct for diverting varying portions of the air passing through said duct from being delivered to said nozzle, depending upon the amount of opening of said valve;

    (f) said valve being configured to be cycled progressively between a first condition wherein a first portion of the air passing through said duct is discharged to ambience and a second condition wherein a second portion of the air passing through said duct is discharged to ambience; and
