In other embodiments, the faucet body may also be internally threaded, and adapted to connect to the adapter 300 via a connector.

The second connecting portion 320 extends into the housing 100 and is sealed with the housing 100. Wherein, the joint 300 is further provided with an assembly through hole 340 and a water inlet part 350 annularly arranged on the assembly through hole 340. In the embodiment of the body, the connector 300 is cylindrical, and has an assembly through hole 340 along the axis thereof, and three fan-shaped water inlet portions 350 are arranged around the assembly through hole 340 to ensure the water inlet area. Without being limited thereto, in other embodiments, one, two or more water inlets 350 may be provided, and the shape of the water inlets 350 may also be circular, square, polygonal, etc., without being particularly limited thereto.
