Wet/dry hose end sprayer

A hose end sprayer apparatus comprising:

• a) a concentrate tank having a bottom wall and a sidewall defining an open top edge, all defining an open interior configured to hold a concentrate therein;
• b) a sprayer head removably mounted onto said concentrate tank, said sprayer head comprising:
• i) an inlet end configured to receive a fluid stream;
• ii) an outlet end configured to discharge the fluid stream;
• iii) a flow tube located between said inlet end and said outlet end and defining an injection orifice therein;
• iv) a suction tube coupled to said injection orifice of said flow tube at a first end, and having a second end located within said open interior of said concentrate tank and above said bottom wall;
• and
• v) a valve assembly located between said inlet end and said flow tube, said valve assembly comprising:
• a) a valve housing defining an inlet opening in communication with said inlet end, a flow opening in communication with said flow tube, and a concentrate opening in communication with said open interior of said concentrate tank, and
• b) a valve body selectively movable within said valve housing, wherein said valve body defines an inlet orifice in communication with said inlet opening, first and second flow orifices selectively positionable to communicate with said flow opening, a concentrate orifice selectively positionable to communicate with said concentrate opening, and a vent opening selectively positionable to communicate with said concentrate opening,
• wherein when said sprayer head is in a closed orientation, said valve body is moved whereby neither said first flow orifice nor said second flow orifice communicates with said flow opening and wherein said concentrate opening is closed by said valve body,
• wherein when said sprayer head is in a wet mode orientation, said valve body is moved whereby said first flow orifice communicates with said flow opening and wherein said vent opening communicates with said concentrate opening to draw concentrate from said concentrate tank into said flow tube, and
• wherein when said sprayer head is in a dry mode orientation, said valve body is moved whereby said second flow orifice communicates with said flow opening and wherein said concentrate orifice communicates with said concentrate opening and is configured to direct a diverted portion of the fluid stream into said concentrate tank.
