Variable water flow and dilution chemical dispenser
View Patent ↗A dispenser for mixing and dispensing a liquid chemical concentrate from a container with a stream of diluting water. The dispenser includes two valve members which control in one instance the water flow and in another instance the amount of concentrate being siphoned into the water flow. The dispenser is of a simplified design yet can afford a variety of different chemical concentrations, as well as various flow rates of the water.
1. A dispenser for dispensing different concentrations of chemical concentrate into a stream of water from a concentrate container at different flow rates comprising:
a body member having a through bore with an inlet end adapted to be connected to a source of pressurized water at one end and an outlet at the opposite end;
a first valve member in fluid communication with the through bore of the body member, the first valve member constructed and arranged with at least two different sized and independent flow channels to provide at least two different flow rates of pressurized water;
a second valve member in fluid communication with the through bore and the concentrate container, the second valve member constructed and arranged to provide a least two different amounts of concentration of chemical concentrate into the through bore; and
the first and second valve members being rotatably positioned on the body member and accessible from outside the body member.
2. The dispenser of claim 1 wherein the second valve member is constructed and arranged to provide three different flow rates.
3. The dispenser of claim 2 wherein the second valve member includes three flow passages of different diameters.
4. The dispenser of claim 1 wherein the through bore is connected to the chemical concentrate.
5. The dispenser of claim 4 wherein the through bore is connected to the chemical concentrate by means of a dip tube in a container.
6. The dispenser of claim 1 wherein the outlet is constructed and arranged to fill a bucket, a bottle or to receive a foam nozzle.
7. The dispenser of claim 1 wherein the body member is adapted to be held by a human hand.
8. The dispenser of claim 7 wherein the first and second valve members are controlled by control dials positioned on a side of the body member, with both dials located on the same side.
9. The dispenser of claim 1 wherein the inlet end is adapted to be connected to a hose.
10. The dispenser of claim 1 wherein the first valve member includes a flow control device.
