Abstract: A watering device for irrigation of non-circular areas is disclosed. The watering device comprises a deflector having an uneven curved surface designed to cause liquid meeting the deflector to reach a distance that changes respective of the uneven surface to cover an irrigation area; a spiral sector object connected to the deflector and providing an adjustable spray orifice for adjusting an irrigation pattern of the watering device; and a two-diameter tubular body connected to the spiral sector object and allowing the liquid to flow from a pipe to the uneven curved surface of the deflector.

Abstract: An irrigating device and a deflector for even spraying of liquid across non-circular areas are presented. The irrigating device includes a base comprising at least a groove; a cap; and a deflector including at least a butterfly ridge, a groove, and a plurality of hydrodynamic ribs, wherein the butterfly ridge is structured with a continuous series of angles to allow equal quantity of liquid per distance on the radius and diagonal, wherein the groove is structured to allow full liquid coverage at a zero point, and wherein the plurality of hydrodynamic ribs are structured to control at least the irrigated distance.
