초록 ▼

A manually actuated liquid sprayer has a ported element selectively movable between a retracted position and an extended position at which the element lies in the path of the spray plume for mitigating the spray. The element has a cylinder with a smooth inner wall defining a turbulence chamber coaxial with the discharge orifice of the nozzle cap to which the element is mounted. A transversely extending perforate wall is located in the cylinder, and has an open port of a size greater than that of the discharge orifice and being coaxial therewith. The element is movable relative to the nozzle cap between the retracted position at which the liquid spray passes through the open port without influence from any portion thereof, and the extended position at which the liquid spray impacts against the smooth inner wall to mix with air in the chamber and passes through the perforate wall to create foam ejected from the element.

A manually actuated liquid sprayer comprising a nozzle containing a discharge orifice for discharge under pressure of a divergent plume of liquid spray in a downstream direction, and a ported element selectively movable between a retracted position and an extended position at which the element lies in the path of the spray plume for mitigating the spray, the element having a cylinder with a smooth inner wall defining a turbulence chamber coaxial with the discharge orifice, a transversely extending perforate wall located in said cylinder, said perforate wall having an open port of a size greater than that of the discharge orifice and being coaxial therewith, and said perforate wall comprising first and second sets of ribs respectively lying in first and second parallel planes, said ribs of said first set being contiguous to said ribs of said second set, said ribs being mutually spaced apart in each said set to define uniformly sized openings therebetween, said ribs of both said sets having flat surfaces facing upstream and lying perpendicular to a central axis of said cylinder for generating foam as the foam impacts against said flat surfaces, the element being mounted on the nozzle for axial movement relative thereto between said retracted position at which the liquid spray passes through the open port without influence from any portion thereof, and said extended position at which the liquid spray impacts against said smooth inner wall to mix with air in the chamber to create foam while passing through said perforate wall which enhances the creation of foam ejected from a downstream end of said cylinder.
