Handle

Cleaning assembly

A push-lock handle assembly includes segments that are interconnected by axial movement using snap-in D-shaped tabs and recesses. Slits and grooves allow the tabs to deflect slightly inwardly during insertion. In another form there is a grip section, at least one pole section, and one accessory attachment section. Simple axial movement snap locks the parts together.

A chemical aspiration sprayer head includes a carrier channel having an inlet, an outlet through which the carrier fluid exits, and an expansion chamber in between the inlet and outlet, a chemical supply channel in flow communication with the expansion chamber of the carrier channel through an aspiration opening, and a bleed line extending from the chemical supply channel between the aspiration opening and the liquid chemical, the bleed line connecting the chemical supply channel in flow communication to ambient air. A control valve assembly is seated in the sprayer head to simultaneously engage the carrier channel and the bleed line and with the carrier channel open, selectively open and close the bleed line to selectively permit ambient air to be drawn into the chemical supply channel in response to the aspiration flow produced by the flow of carrier fluid.
