Rotary spray shower head

A rotary spray shower head, comprising a main body, a water distributing plate, a rear faceplate, an impeller, a pinion, a driven gear, a water outlet head assembly and a discharge faceplate;

• the water distributing plate, being assembled under the main body, with the main body having an opening on one side and a closing on an opposing side thereof;
• the impeller, composed of blades disposed with an open space therebetween, being non-coaxially assembled under the water distributing plate through an eccentric shaft non-coaxially fixed beneath the water distributing plate;
• the pinion being concentrically assembled under the impeller;
• the rear faceplate, non-coaxially enveloping the impeller and the pinion inside a circular wall extending upwards parallel to a central axis of the rear faceplate under the water distributing plate, with a power room, being non-coaxially formed between the water distributing plate and the rear faceplate for accommodating the impeller;
• inclined openings being formed in a wall of the power room extending upwards parallel to the central axis of the rear faceplate, ordinary water holes being formed in the rear faceplate and the water distributing plate correspondingly;
• the discharge faceplate being sealingly assembled under the rear faceplate, a through hole being formed in a middle of the discharge faceplate, ordinary discharge openings being formed in a periphery of the discharge faceplate;
• the driven gear being mounted between the rear faceplate and the discharge faceplate, annular inner teeth of the driven gear meshing with the pinion;
• the water outlet head assembly being located in the through hole of the discharge faceplate, the water outlet head assembly comprising a hollow connecting stem, a water cavity and a water outlet, the hollow connecting stem sealingly passing through the through hole of the discharge faceplate to be fixed in a shaft hole of the driven gear.
