Patent ID: 8083161

Claim:
A spray device comprising: a handle defining a grip thereon, said handle comprising: an electric power supply; a voltage multiplier circuit coupled to said electric power supply; a motor coupled to said electric power supply and responsive thereto; a control member configured to electrically connect said electric power supply and said motor; and a driver rotationally coupled to said motor; and a fluid dispensing cartridge supported by said handle through a cantilevered connection therebetween, said cartridge comprising: a body defining a fluid chamber therein; a piston disposed in said fluid chamber and responsive to said driver such that rotation of said driver forces movement of said piston to effect dispensing of a fluid disposed in said fluid chamber; a plurality of nozzles in fluid communication with said fluid chamber such that upon movement of said piston therein, at least a portion of said fluid is discharged from said fluid chamber through said plurality of nozzles in a spray pattern substantially defined by said plurality of nozzles, wherein said nozzles are made from an electrically conductive plastic; and a connection to establish electrical communication between said voltage multiplier circuit and said plurality of nozzles such that upon operation of said spray device, an electric field is set up that is sufficient to comminute said fluid being dispensed from said plurality of nozzles.
