[0032] In some embodiments of this utility model, the outer shell 100 is provided with a first mounting part 110, and the left end of the water outlet shell 200 is provided with a second mounting part 270. The first mounting part 110 and the second mounting part 270 are rotatably connected. The first mounting part 110 is provided with at least one groove 111.

[0038] In some embodiments of this utility model, the waterfall outlet cavity 250 is provided with a grid plate 600, a rectifier plate 700, and several rectifier columns 800. The grid plate 600 is located between the rectifier plate 700 and the waterfall outlet, and the rectifier columns 800 are located behind the rectifier plate 700. The several rectifier columns 800 are distributed at intervals.

The rectifier plate 700 is provided with multiple jet holes 710, and the jet holes 710 are directly opposite the ribs 610. The water flows into the waterfall outlet cavity 250 from the second inlet 220. At this time, the water flow is relatively rapid and needs to pass through the rectifier columns 800, the jet holes 710, and the ribs 610 for triple rectification. This ensures that the water flow is in a uniform laminar flow state when it reaches the waterfall outlet, resulting in balanced and transparent water output. It also ensures that the sprayed waterfall water does not shrink or branch over a long distance. The jet hole 710 must be directly aligned with the rib 610 to effectively dissipate the impact force of the water flow and play a role in rectifying the flow.

[0039] In some embodiments of this utility model, an inlet valve body 900 is also included. The inlet valve body 900 is installed inside the outer casing 100.

The first switch valve core 931 is used to control the on / off connection between the main water passage 920 and the first water outlet passage 950. One end of the second water outlet passage 960 is connected to the third water inlet 320, and the other end is connected to the second valve core seat 940. The second switch valve core 941 is used to control the on / off connection between the main water passage 920 and the second water outlet passage 960.

[0040] In some embodiments of this utility model, a faucet 1000 is also included. The faucet 1000 is fixed to the outer casing 100. A third valve core seat 970 and a third water outlet 980 are formed on the inlet valve body 900. A third switch valve core 971 is installed inside the third valve core seat 970. One end of the third water outlet 980 is connected to the faucet 1000, and the other end is connected to the third valve core seat 970. The third switch valve core 971 is used to control the on / off connection between the main water circuit 920 and the first water outlet 950. Currently, the faucet 1000 used in kitchen products mostly uses flexible hoses to connect the various water outlet units, resulting in numerous pipes under the countertop and easy errors in hose connection during installation. This utility model integrates three water circuits into one inlet valve body 900. When the water outlet device is installed on the sink, it only needs to be connected to the main inlet 910, improving installation efficiency.
