Ready-to-use hose end sprayer

Abstract

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.
