READY-TO-USE HOSE END SPRAYER
A ready-to-use sprayer comprises a container defining an interior compartment for containing a liquid product, a housing having a main chamber and a grip portion, a nozzle in selective fluid communication with the outlet of the fluid chamber, and a pivot switch on the exterior of the housing for selecting a fluid flow condition for the main chamber.
1 . A sprayer comprising:
a container defining an interior compartment for containing a substance liquid;
a housing coupled with the container, having:
a grip portion;
a main chamber having a substance liquid inlet, a carrier liquid inlet, and an outlet; and
a carrier liquid receiving port;
a nozzle in selective fluid communication with the outlet of the main chamber; and
a pivot switch on the exterior of the housing for selecting a fluid flow condition for the main chamber, wherein the pivot switch is operatively coupled to a pivot arm to translate movement of the pivot switch to the main chamber;
wherein the grip portion is positioned within a first horizontal plane below a separate second horizontal plane containing the nozzle and above a further separate third horizontal plane containing the carrier liquid receiving port.
2 . The sprayer of claim 1 , wherein the grip portion is curved.
3 . The sprayer of claim 1 , wherein the grip portion and the pivot switch are positioned so that a user can hold the sprayer and affect the pivot switch with one hand.
4 . The sprayer of claim 1 , wherein the pivot switch is configured to travel along an arcuate path.
5 . The sprayer of claim 1 , further comprising:
a carrier liquid conduit in selective fluid communication with the main chamber at the carrier liquid inlet;
a substance liquid conduit in selective fluid communication with the main chamber at the liquid product inlet, and with the container.
6 . The sprayer of claim 5 , wherein the pivot switch controls the flow of a carrier liquid and a substance liquid into the main chamber.
7 . The sprayer of claim 5 , wherein the substance liquid conduit is positioned substantially perpendicular to the main chamber.
8 . The sprayer of claim 1 , wherein the container is coupled to the housing by a snap-fit connection.
9 . The sprayer of claim 5 , wherein the main chamber is configured to generate a vacuum to enable mixing of a carrier liquid and a substance liquid.
10 . The sprayer of claim 5 , wherein the main chamber further comprises:
a rear chamber;
a middle chamber; and
a front chamber.
11 . The sprayer of claim 10 , wherein the rear chamber, the middle chamber, and the front chamber have different dimensions.
12 . The sprayer of claim 10 , wherein the middle chamber has a smaller diameter than that of each of the rear chamber and the front chamber.
13 . The sprayer of claim 10 , wherein the main chamber is configured so that the mixing of a carrier liquid and a substance liquid occurs within the front chamber.
14 . The sprayer of claim 10 , wherein the rear chamber, the middle chamber, and the front chamber are configured to effect turbulence in a carrier liquid as the carrier liquid passes through the main chamber and over the substance liquid inlet.
15 . The sprayer of claim 1 , wherein the carrier liquid receiving port is threaded.
16 . The sprayer of claim 10 , wherein the main chamber has at least three operating positions, comprising:
a first operating position, wherein the main chamber is not in fluid communication with either the carrier liquid conduit or the substance liquid conduit;
a second operating position, wherein the main chamber is in fluid communication with both the carrier liquid conduit and the substance liquid conduit; and
a third operating position wherein the main chamber is fluid communication with the carrier liquid conduit but not with the substance liquid conduit.
