When the spray ring 70 is mounted to the tub cover 80, the baffle plate 72 is located on a side of the first shielding sheet 83 facing the annular body 61, that is, the baffle plate 72 is located between the first shielding sheet 83 and the annular body 61, and a certain lateral spacing is maintained between the baffle plate 72 and the first shielding sheet 83. With this arrangement, the first shielding piece 83 can protect the nozzle 70, and prevent the nozzle 70 from being damaged due to pulling of clothes, thereby affecting the reliability of the shower ring 60.

The side of the baffle plate 72 facing the outlet of the spray pipe 71 has an arc-shaped curved surface, and spray water flowing out through the spray holes can be ejected from the spray opening and present spiral waterfall-shaped water flow in the inner barrel 30 after being shielded by the baffle plate 72. It will be appreciated that the baffle 72 may be an arcuate sheet; alternatively, the baffle plate 72 has a plate-shaped structure with a certain thickness, and one side of the baffle plate 72 is provided with an arc-shaped curved surface, and the arc-shaped curved surface is located at one side of the baffle plate 72 facing the outlet of the shower pipe 71.

Further, the curved surface may be a uniform spherical surface or a uniform concave surface disposed on the baffle plate 72. The preferred embodiment is that the baffle 72 has a concave cambered sheet structure to facilitate the fabrication of the nozzle 70. The spray pipe 71 and the flow baffle plate 72 can be an integral structure manufactured by adopting an injection molding process, and the two are integrally in a spoon-shaped structure, so that the connection strength between the flow baffle plate 72 and the spray pipe 71 is enhanced.

The angle b of the second angle ranges from 0 ° to 50 °.

Preferably, the second included angle may range between 15 ° and 20 °. The angle of the baffle plate 72 can be arranged with reference to the angular arrangement of the shower pipes 71, for example, the angle of the baffle plate 72 can be 10 ° or 15 °, and the two different second angles can be staggered. Alternatively, the nozzles 70 on one side of the spray ring 60 may be mounted at an angle of 10 ° and the other side may be 15 °.
