Abstract:
1. A manually adjustable fluidic spray device, comprising: (a) a fluidic circuit base having a boundary surface with opposing edges left side and right side surfaces, a front surface and at least first, second and third primary projections extending from said base boundary surface, said first, second and third primary projections being configured and spaced apart from one another to provide flow passages therebetween and provide an interior geometry for said flow passages to define a fluidic circuit having a power nozzle and an interaction region located downstream of said power nozzle, and wherein said flow passages are proximate said base left side and right side surfaces and configured so that said fluidic circuit base flow passages have no edge boundaries defined in said left side and right side surfaces; (b) a primary housing having an outer surface with a front face that includes an opening to a primary housing socket cavity having a boundary surface that extends into said primary housing, wherein a portion of said socket cavity boundary surface has a sphere-shaped curvature; (c) a secondary housing having an spherical outer surface with a rear face opposing a front face that includes an opening to a secondary housing cavity having a planar boundary surface, wherein said secondary housing cavity's planar boundary surface extends from said front face opening to a rear face opening, and wherein said secondary housing cavity is configured to receive said fluidic circuit base with said fluidic circuit's first, second and third primary projections defining contact points with said secondary housing cavity's planar boundary surface, wherein said left side and right side surfaces are configured to define edge boundaries for said fluidic circuit base flow passages when said fluidic circuit base is inserted in said secondary housing's cavity; and (d) wherein said front portion of said secondary housing cavity defines a passage forming the interior geometry for a throat portion of said fluidic circuit.
