According to above-mentioned theory, the technical solution of the utility model is: non-circular spraying district, comprise a wholecircle impact driven sprinkler, and be characterized in that this wholecircle impact driven sprinkler 1 also is provided with two annexes:
The pad 2 of water hole that links to each other with quick reducer union and have with 1 rotation of wholecircle impact driven sprinkler;
One is arranged on the pad 3 that has groove and water hole on the joint;
Pad 2 is placed in the groove of water hole pad 3, and pad 3 is fixed in the reducer union of wholecircle impact driven sprinkler 1, and the one side of pad [3] has boss, and boss matches with groove in the quick reducer union.
Some other characteristics of the present utility model are that the water hole on pad 2 and the pad 3 is circle or triangle or rectangle or ellipse or arbitrary plane geometric figures such as trapezoidal or polygon; Water hole on pad 2 and the pad 3 is for evenly arranging.
The utility model is owing to increased a pad and a pad of installing with the rotation of wholecircle impact driven sprinkler on the joint of water inlet, therefore, when shower nozzle rotates because water inlet cross-section of river shape and area produce clocklike changes, and then influence pipe internal pressure and sprinkler pattern range.Shower nozzle rotates one-period, repeatedly maximum occurred as cross-section of river shape and area, and the maximum of corresponding number of times also can appear in its corresponding range, reflects that from spraying figure occurred a plurality of angles exactly, the sprinkling figure of a non-circle has just formed.
