Spray pattern adjustment for mop
View Patent ↗A sprayer assembly that includes a reservoir for storing liquid, a pump in fluid communication with the reservoir, first and second supply tubes in fluid communication with the pump wherein the pump is configured to draw liquid from the reservoir and discharge the liquid into the first and second supply tubes, a first nozzle in fluid communication with the first supply tube, a second nozzle in fluid communication with the second supply tube, and a collar having at least one protrusion and rotatable between a first position in which the at least one protrusion pinches closed the first supply tube but not the second supply tube, and a second position in which the at least one protrusion pinches closed the second supply tube but not the first supply tube.
1. A sprayer assembly, comprising:
a reservoir for storing liquid;
a pump in fluid communication with the reservoir;
first and second compressible supply tubes in fluid communication with the pump, wherein the pump is configured to draw liquid from the reservoir and discharge the liquid into the first and second supply tubes;
a first nozzle in fluid communication with the first supply tube;
a second nozzle in fluid communication with the second supply tube; and
a collar, the first and second supply tubes passing through the collar, and the collar having at least one protrusion extending radially inward and rotatable between a first position in which the at least one protrusion pinches closed the first supply tube but not the second supply tube, and a second position in which the at least one protrusion pinches closed the second supply tube but not the first supply tube.
2. The sprayer assembly of claim 1 , wherein:
the at least one protrusion includes a first protrusion and a second protrusion;
the first protrusion pinches closed the first supply tube with the collar at the first position; and
the second protrusion pinches closed the second supply tube with the collar at the second position.
3. The sprayer assembly of claim 1 , wherein a portion of the first supply tube is adjacent a first compression surface of a support block, and wherein the at least one protrusion pinches closed the first supply tube against the first compression surface with the collar at the first position.
4. The sprayer assembly of claim 3 , wherein a portion of the second supply tube is adjacent a second compression surface of the support block, and wherein the at least one protrusion pinches closed the second supply tube against the second compression surface with the collar at the second position.
5. The sprayer assembly of claim 1 , wherein:
a portion of the first supply tube is adjacent a first compression surface of a support block;
the at least one protrusion includes a first protrusion that pinches closed the first supply tube against the first compression surface with the collar at the first position;
the first protrusion includes a straight leading edge that terminates in a rounded end; and
the first compression surface has a concave shape that matches a shape of the rounded end.
6. The sprayer assembly of claim 5 , wherein:
a portion of the second supply tube is adjacent a second compression surface of the support block;
the at least one protrusion includes a second protrusion that pinches closed the second supply tube against the second compression surface with the collar at the second position;
the second protrusion includes a straight leading edge that terminates in a rounded end; and
the second compression surface has a concave shape that matches a shape of the rounded end of the second protrusion.
7. The sprayer assembly of claim 1 , wherein:
the first and second nozzles are configured to produce spray patterns that are different from each other.
8. The sprayer assembly of claim 7 , wherein:
the first nozzle has a narrow opening for creating a narrow output stream of the liquid; and
the second nozzle has an elongated opening for creating an elongated output stream of the liquid.
9. The sprayer assembly of claim 1 , wherein the collar is rotatable to a third position in which neither of the first and second supply tubes are pinched closed.
10. A sprayer assembly, comprising:
a reservoir for storing liquid;
a pump in fluid communication with the reservoir;
an output tube in fluid communication with the pump, wherein the pump is configured to draw liquid from the reservoir and discharge the liquid into the output tube;
first and second supply tubes in fluid communication with the output tube;
a first nozzle in fluid communication with the first supply tube;
a second nozzle in fluid communication with the second supply tube; and
a collar, the first and second supply tubes passing through the collar, and the collar having first and second protrusions extending radially inward and rotatable between a first position in which the first protrusion pinches closed the first supply tube, and a second position in which the second protrusion pinches closed the second supply tube.
11. The sprayer assembly of claim 10 , wherein the first supply tube is not pinched closed with the collar in the second position, and wherein the second supply tube is not pinched closed with the collar in the first position.
12. The sprayer assembly of claim 10 , further comprising:
a one-way valve disposed in the output tube.
13. The sprayer assembly of claim 10 , wherein a portion of the first supply tube is adjacent a first compression surface of a support block, and wherein the first protrusion pinches closed the first supply tube against the first compression surface with the collar at the first position.
14. The sprayer assembly of claim 13 , wherein a portion of the second supply tube is adjacent a second compression surface of the support block, and wherein the second protrusion pinches closed the second supply tube against the second compression surface with the collar at the second position.
15. The sprayer assembly of claim 10 , wherein:
a portion of the first supply tube is adjacent a first compression surface of a support block;
the first protrusion pinches closed the first supply tube against the first compression surface with the collar at the first position;
the first protrusion includes a straight leading edge that terminates in a rounded end; and
the first compression surface has a concave shape that matches a shape of the rounded end.
16. The sprayer assembly of claim 15 , wherein:
a portion of the second supply tube is adjacent a second compression surface of the support block;
the second protrusion pinches closed the second supply tube against the second compression surface with the collar at the second position;
the second protrusion includes a straight leading edge that terminates in a rounded end; and
the second compression surface has a concave shape that matches a shape of the rounded end of the second protrusion.
17. The sprayer assembly of claim 10 , wherein:
the first and second nozzles are configured to produce spray patterns that are different from each other.
18. The sprayer assembly of claim 17 , wherein:
the first nozzle has a narrow opening for creating a narrow output stream of the liquid; and
