Patent ID: 8278775

Claim:
A swirly fluid sprinkler, comprising: a sprinkling body, having a fluid inlet and a fluid outlet; a fluid guide, disposed inside the fluid inlet of the sprinkling body and configured with a plurality of swirl channels for dividing a fluid flow into a plurality of swirly fluid flows, wherein each swirl channel is formed spinning along a specific axis so as to result in an appearance of vortices in the fluid flowing therein; and an electrical generator, disposed inside the sprinkling body at a position corresponding to the fluid guide, having a plurality of blades, each inclinedly disposed thereon by an inclining angle; wherein, an angle is formed between a surface of each blade facing toward the fluid guide and its corresponding swirly fluid flow impinging thereon so that a propelling force from the swirly fluid flow is received thereby to be used for rotating the electrical generator and thereby causing the electrical generator to generate an electrical power output.
