Sprayer
A sprayer system having a sprayer assembly adaptable to a variety of sizes and shapes of containers. The sprayer assembly includes a dual venturi in the flow conduit to provide even pressure and consistent flow in the spray volume. A metering device is coupled to the flow conduit for accurate and reliable regulation of mixture ratios. A dip tube, coupled to the fluid conduit, is adaptable to a variety of container orifices. In addition to acting as a conduit for passage of concentrate into the sprayer assembly, the dip tube may also be used as a cutting device to open the container into which it will be inserted. By adapting to a variety of container orifices, the dip tube allows the sprayer assembly to fit to a variety of containers.
1. A sprayer system comprising:
a container having an additive therein;
a dip tube for insertion in the container;
a spray nozzle;
a sprayer device having a housing and a fluid conduit disposed in the housing and being coupled to the dip tube, wherein the fluid conduit includes a check valve and a dual venturi in parallel, said sprayer device further having a first inlet, a second inlet, and an outlet, wherein the first inlet is connected to a flexible hose, the second inlet is connected to the dip tube, and the outlet is connected to said spray nozzle;
the flexible hose having a first end and a second end, wherein the first end is connected to the sprayer device and the second end is connected to a fluid source having fluid therein;
a metering device coupled to the fluid conduit to vary the ratio of fluid to additive;
wherein the fluid conduit comprises a first passageway connecting the first inlet to the outlet, and a second passageway connecting the second inlet to the outlet, and wherein the dual venturi comprises a first venturi in the first passageway and a second venturi in the second passageway; and
wherein the fluid and the additive are mixed in the fluid conduit and expressed from the outlet through the spray nozzle.
