Abstract: A gardening-used variational sprinkling head with fully discharging openings, composed of a variational water-discharging cover and a base member associated therewith. The sprinkling head is associated with a sprinkling gun. The sprinkling gun has an inner water outlet. The water-discharging cover is formed with radial ribs inward projecting from inner periphery thereof to define several fully discharging openings. A circular mesh plate is placed within the radial ribs. Six different variational sprinkling holes and two close holes are integrally annularly arranged on a central portion of the mesh plate. The six variational sprinkling holes respectively have six rearward extending hollow posts which respectively abut against six water inlets annularly arranged on the base member. The base member is connected with the mesh plate by ultrasonic fusion and spaced from the radial ribs by a space so that water can pass through the fully discharging openings.

Abstract: An improved spray gun includes a governing ring, wherein an inner thread and plural guiding ribs are installed in the center of the governing ring. A netted water flow room having a water outlet is positioned at the guiding ribs of the governing ring, and a water stop room is positioned proximate the water outlet in the top of the netted water flow room. A coning foggy water flow room is installed at the top of the water stop room. A netted cover is positioned over the foggy water flow room, wherein the netted cover is connected to the governing ring by a connecting cap. An outer thread in the end of the governing ring fits with the inner thread of the connecting cap. A center stem is installed within the governing ring, and two water stop rings are mounted on the center stem, one on each side of a water outlet in the middle of the center stem.
