Fluidic oscillator

摘要

A fluidic oscillator contains at least one channel including an interacting cavity disposed therein, a first inlet communicating with the interacting cavity to flow fluid inward, and a first outlet communicating with the 5 interacting cavity to spray the fluid flowing through the interacting cavity outward, characterized in that: at least one turbulent flow passage is used to guide the fluid to flow into the interacting cavities from one of two opposite first longitudinal walls of the interacting cavities so that a turbulent flow effect is generated in the interacting cavities, and then the fluid flows out of the first 0 outlets to generate oscillatory spray. 12 -13
