Abstract: A water outlet structure allowing a nozzle to generate different spray patterns and a water outlet device using the water outlet structure are provided. The water outlet structure includes: a housing, a water outlet cover, a water dispersion assembly, a water separation assembly, a water oblique assembly, and a switching assembly. At least two water inlet holes are defined through the housing. The water outlet cover is connected to the housing, and a plurality of water outlet portions are defined through the water outlet cover. The water dispersion assembly includes a first water dispersion hole and a second water dispersion hole. The water separation assembly directs pressurized water into a first chamber or a second chamber. The water oblique assembly forms the first chamber with the water separation assembly, and forms the second chamber with the water outlet cover.
