Sprinkler Structure

A sprinkler structure comprising:

• a shell base having a water inlet hole for water current to flow in;
• a water nozzle having a water outlet surface, said water outlet surface including a plurality of spiracles is disposed thereon for spraying water;
• a water conveyance element being disposed on said shell base, said water conveyance element being connected to said water nozzle, said water conveyance element conveying said water current from said water inlet hole to said water nozzle;
• an eccentric gear device being disposed on said shell base and being coupled to said water conveyance element, said eccentric gear device performing an eccentric movement in responding to an external force and driving said water conveyance element to perform a reciprocating pivotal turning action;
• a drive gear device being disposed inside said shell base, said drive gear device being coupled to said eccentric gear device, wherein said drive gear device is rotated in response to said water current flowing in from said water inlet hole so that said eccentric gear device drives said water conveyance element to perform said reciprocating pivotal turning action, wherein said water nozzle is driven by said reciprocating pivotal turning action to alter an angle of said water outlet surface continuously within an angle range;
• and
• a fixing base connected to said water nozzle and said shell base for securing said water nozzle and said shell base.
