Patent ID: 7219848

Claim:
An electrically-operated fluid sprayer comprising: a fluid pump including an inlet port, an outlet port, a pump chamber, and a piezoelectric element; drive circuitry coupled to said piezoelectric element such that said piezoelectric element is deformed to vary the volume of said pump chamber in order to pump fluid into said inlet port and into said pump chamber and discharge fluid from said pump chamber out said outlet port; an electrical power source coupled to said drive circuitry, said electrical power source comprising at least one battery; an electrical switch for selectively activating said drive circuitry to thereby selectively control deformation and displacement of said piezoelectric element; spin mechanics disposed downstream from said outlet port of said fluid pump; and a discharge nozzle coupled to said spin mechanics; wherein said pump, discharge nozzle, spin mechanics, at least one battery, electrical switch, and drive circuitry are supported in a hand-holdable housing supporting a coupling that removably engages a reservoir of liquid fluid to be dispensed by the fluid sprayer.
