DOUBLE BARREL SPRAYER

摘要

A double barrel sprayer (2) for applying a diluted product such as a diluted cleaning solution to a surface for cleaning thereof and rinsing the diluted product from the surface by spraying a water-only rinse onto the surface. The sprayer (2) can include a force fitted orifice plate (50) with one or more holes (52a and 52b) for adjusting the water/product mixing ratio or an insert having passages therein for providing a desired product dilution ratio. To provide different spray patterns for the water-rinse or diluted product, the sprayer (2) can include a shroud having suitably shaped exit holes. The sprayer (2) includes separate flow paths for water-only rinse (23) and the diluted product (24). The flow path for the diluted product (24) includes a mixing chamber (28) in which concentrated product is siphoned from a container (6) and mixed with water supplied by a garden hose (4). Prior to mixing with the water, the concentrated product passes through the orifice plate (50) or insert to provide a substantially constant water/product ratio over a wide range of water pressures. The sprayer (2) includes a removable cover (30) which includes a pair of outlets suitably sized and shaped to obtain desirable spray patterns for water-only rinse and the diluted product sprayed from the sprayer (2). A rotatable valve (40) allows selective application of water or diluted product.
