Patent ID: 8201758

Claim:
A fluid spraying device comprising a fluid oscillator being used to oscillate fluid to generate spraying water and including: an inlet to flow fluid into the fluid oscillator; at least one power nozzle communicating with the inlet to accelerate the speed of the fluid from the inlet; an interacting chamber communicating with the power nozzle to flow the fluid from the power nozzle and further flow the fluid outward to be oscillated; an outlet being in communication with the chamber to oscillate the fluid from the chamber to generate spraying water, characterized in that: the fluid oscillator includes a first portion and a second portion; a connection of the first and the second portions passes through the power nozzle to flow fluid through a predetermined traveling position, and the first portion includes the inlet and a section of the power nozzle, and the second portion includes the outlet and another section of the power nozzle, by using a movement of the first and the second portions, a cross sectional area of the fluid at the connection of the first and the second portions is changed to adjust spraying water from the outlet; wherein the first portion rotates relative to the second portion.
