The conventional sprinkler nozzle is generally capable of emitting water in a specific pattern and is therefore limited in its use. For this reason, various sprinkler nozzles must be ready on hand to meet the need of a situation in which the water emission must be brought about in various patterns. It is time-consuming and frustrating for a user to sort out a desired sprinkler nozzle. In addition, various sprinkler nozzles must be purchased at an additional cost and provided with an additional storage space.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a versatile sprinkler nozzle capable of emitting water in various patterns.
The sprinkler nozzle of the present invention comprises a main body, an inner cap, and an outer cap. The inner cap and the outer cap are held by the main body. The inner cap is provided with a plurality of water inlets of various forms, whereas the outer cap is provided with a plurality of water outlets of various forms and two closing holes. Through the cooperation of the water inlets of the inner cap with the water outlets and the closing holes of the outer cap, the sprinkler nozzle of the present invention is capable of emitting water in various patterns.
