A spray nozzle (10) includes a nozzle body (12) and a chemical containing cartridge (28) releasably attached to the nozzle body (12). The cartridge (28) can be adapted to be releasably secured to the nozzle body (12) at the outlet end (16), the inlet end (14), or on the nozzle body (12) itself, in order to dispense a chemical contained within the cartridge into a water stream flowing through the nozzle. The nozzle (10) also includes a dispensing mechanism utilized to control the amount of the chemical dispensed into the water stream. The dispensing mechanism can be disposed on the nozzle body (12), or directly on the cartridge (28) itself.

The invention claimed is: 1. A cleaning spray nozzle which comprises: a nozzle body including an inlet for receiving water; a trigger valve operable to infinitely vary the flow of water through the water flow continuum from a fully open continuum to a fully closed continuum; a toggle valve downstream of the trigger valve, the toggle valve being operable to direct flow between a clean water flow channel and a chemical dispensing flow channel; an outlet for discharging either clean water from the clean water flow channel or clean water and a chemical from the chemical dispensing flow channel downstream of the toggle valve; and a cartridge releasably secured to a portion of the nozzle body, the cartridge containing a chemical therewithin, the cartridge having an outlet that permits the flow of the chemical into the chemical dispensing flow channel. 2. The spray nozzle of claim 1 wherein the cartridge is releasably attached at the inlet of the nozzle body. 3. The spray nozzle of claim 1 wherein the cartridge is releasably attached at the outlet of the nozzle body. 4. The spray nozzle of claim 1 wherein the cartridge is formed from a plastic material. 5. The spray nozzle of claim 1 wherein the cartridge is generally translucent such that the contents of the cartridge are visible to a user. 6. The spray nozzle of claim 1 wherein the cartridge is adapted to hold a chemical in liquid, solid, granule, or other form within the cartridge. 7. A spray nozzle for optionally dispensing an amount of a chemical into a water stream flowing from the spray nozzle comprising: a nozzle body having an inlet end, an outlet end and a conduit therethrough; a trigger valve disposed between the inlet end and the outlet end, the trigger valve being operable to control the flow of water between the inlet end and the outlet end; a toggle valve, the toggle valve being operable to direct water to flow through a clean water flow channel or a chemical dispensing water flow channel and a chemical containing cartridge attached to the nozzle body, the cartridge being operable to dispense water into the chemical dispensing water flow channel. 8. The spray nozzle of claim 7 including means for permitting the adjustment of the chemical containing cartridge to control the amount of chemical to be dispensed. 9. The spray nozzle of claim 7 wherein the cartridge is releasably attached to the inlet end of the nozzle body. 10. The spray nozzle of claim 7 wherein the cartridge is releasably attached to the outlet end of the nozzle body. 11. The spray nozzle of claim 7 wherein the cartridge is configured within the spray nozzle and functionally disposed between the inlet and the outlet of the spray nozzle. 12. The spray nozzle of claim 7 wherein the cartridge is formed from a plastic material. 13. The spray nozzle of claim 7 wherein the cartridge is generally translucent such that the contents of the cartridge are visible to a user. 14. The spray nozzle of claim 7 wherein the cartridge is adapted to hold a chemical in liquid, solid, granule, powder, or other form within the cartridge.
