Abstract
An improved airless electric sprayer is disclosed having superior balance, portability, receptacle interchangeability, cleanability and a non-tipping stand feature. The user's hand conveniently grasps a piston grip in close proximity to the nozzle for accurate spray control at a position generally above the combined center of mass of a motor housing and receptacle for balanced comfortable use. The invention includes a release and lock arrangement affording handy receptacle attachment and disengagement without need for unscrewing the receptacle from the body of the sprayer, which also prevents spillage. To prevent clogging, any unsprayed liquid is allowed to accumulate around a reduced piston section and drain therefrom back into the receptacle. The housing has an access panel to expose pump assembly for convenient cleaning.
