A spraying device having a sprayer head and an interchangeable, disposable, recyclable and/or biodegradable, and attachable cartridge, capable of diluting and dispensing a chemical. The device has a rotatable barrel valve to select whether to fill the cartridge, spray the diluted chemical, or prevent any flow. The device further has a pair of coupling tubes which permit the easy connection of the sprayer head to the cartridge in a way to cause, by aspiration, the partially diluted chemical to enter the sprayer head for further mixing and discharge. A rupturable or replaceable membrane is placed across the top of the cartridge to contain the concentrated chemical prior to use. A plug closure permits the addition of a chemical to the cartridge.

A spraying apparatus, said spraying apparatus comprising: a sprayer head further comprising: a fluid inlet conduit; a rotatable barrel valve having a flow channel network such that when in a first, spray position, a first fluid is directed to flow from said inlet conduit through a first fluid discharge conduit into a mixing chamber, and when rotated to a second, fill position, said first fluid is directed to flow from said inlet conduit through a fluid inlet coupling tube, said fluid inlet coupling tube having a distant end extending through the bottom edge of a sealed housing, and when rotated to a third, off position, no flow occurs; a fluid outlet coupling tube having a first end in fluid communication with and terminating at said mixing chamber, said fluid outlet coupling tube having a distant end extending through said bottom edge of said sealed housing in a direction nearly equivalent to that of said fluid inlet coupling tube so that said first fluid flowing through said first fluid discharge conduit can draw a second fluid from said fluid outlet coupling tube into said mixing chamber, and that a resulting mixed fluid is discharged through a second discharge conduit, into the environment, said housing sealing said sprayer head to permit flow only through said conduits, coupling tubes, valve, and mixing chamber; an interchangeable and disposable cartridge able to contain said second fluid therein a said cartridge further comprising: a cartridge housing for containment of said second fluid within said cartridge, having an open top end and a closed bottom end; a cartridge lid sealably attached to said open top end, said lid having a top, and a fluid inlet, said fluid inlet sealably mateable with said distant end of said fluid inlet coupling tube, said lid also having a dip tube extending downward from said lid nearly to said bottom end of said cartridge housing, said dip tube sealably mateable with said distant end of said fluid outlet coupling tube to attach said sprayer head to said cartridge, so that when said barrel valve is in its second, fill position, said first fluid can be directed to flow into said cartridge to partially dilute said second fluid, and so that when said barrel valve is subsequently rotated to said first, spray position, said first fluid can be directed to flow into said mixing chamber and past said fluid outlet coupling tube to withdraw and further dilute said second fluid from said cartridge.
