Easy sprayer: a sprayer assembly in which a foot operated pump is used to pressurize the sprayers' tank

摘要

In this design of a garden sprayer, a foot pump and the tank of a sprayer are connected to a common base. The tank is pressurized by stepping repeatedly on the foot-operated air pump, pushing air through the airline of the foot pump, then through an air inlet in the upper section of the tank. The built up air pressure in the tank pushes the liquid in the tank out through the sprayer hose, then through the sprayer nozzle when the nozzle valve is opened.
