Abstract:
An air-pressure sprayer structure, comprising:a container, a cover unit, an air-pump unit, a spray mouthpiece unit, and a water-stop valve wherein said container is provided with a water-inlet opening and external threads at an upper section thereof; said cover unit, joined to said container via said external threads thereof, has a press body disposed at an upstream thereof which can control movement of said water-stop valve disposed in a sleeve pipe; said air-pump unit, accommodated within said container, comprises a valve rod having a head knob extending out of said cover unit at a top thereof, and an air- relief valve disposed at an end thereof wherein said engaged valve rod and air-relief valve are led and joined to a sleeve cylinder; said spray mouthpiece unit, attached to said cover unit at a downstream side thereof, can be moved upwards or downwards to point at different directions for use; whereby, said press body having a slide block can be located for constant discharge of water out of said spray mouthpiece without interruption; and the force applied onto said press body being in parallel with a longitudinal axis of said water-stop valve thereof, allowing a balance of forces in operation and effectively preventing the distortion of said water-stop valve and thus a leak of both air and water from said container.
