A water outlet structure for generating different spray patterns at its water outlet portions, comprising: a housing; a water outlet cover; a water dispersion assembly; a water separation assembly; a water oblique assembly; and a switching assembly; wherein 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 comprises a first water dispersion hole in communication with a first water inlet hole, and a second water dispersion hole in communication with a second water inlet hole; the water separation assembly is configured to direct pressurized water into a first chamber or into 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; the water oblique assembly comprises a straight flow region and an oblique flow region disposed on a same plane; the pressurized water flows into the water separation assembly through the second water dispersion hole, directly flows into the second chamber through the straight flow region, and flows out from the water outlet portions through the second chamber, to form a first water flow; the pressurized water flows into the water separation assembly through the first water dispersion hole, flows into the oblique flow region through the first chamber, swirls inside of the water outlet portions after flowing through the oblique flow region, and flows out from the water outlet portions, to form a second water flow; and the pressurized water enters the first chamber and the second chamber respectively through the first water dispersion hole and the second water dispersion hole, swirling water after flowing through the oblique flow region and straight-flow water after flowing through the straight flow region mix with each other and flow out from the water outlet portions, to form a third water flow; and the switching assembly is configured to selectively direct the pressurized water into the water inlet holes (11, 12); wherein the oblique flow region comprises a plurality of oblique flow groups; each of the plurality of the oblique flow groups comprises two or more water oblique holes; the water oblique holes are arranged in a staggered manner, and a water outlet end of each of the plurality of the oblique flow groups is in communication with one of the water outlet portions; characterized in that the water oblique holes are defined obliquely with respect to a water outlet surface or a horizontal plane and point to an end of the water outlet portions and the water inlet areas of the water oblique holes are larger than areas of water outlet holes of the water outlet portions. a housing;
