Abstract
A centrifugal water spray structure is provided. The centrifugal water spray structure includes: a chamber having a chamber axis and an opening, a water jetting device for jetting water into the chamber in a direction not parallel to the chamber axis, thereby creating a vortex flow in the chamber, and a rotary plug received in the chamber. One end of the rotary plug abuts an edge of the opening of the chamber in a manner that sealing is formed between the rotary plug and the edge of the opening, and the other end of the rotary plug is a free end so that the rotary plug is able to be driven to rotate about the chamber axis by the vortex flow. A plug water passage is formed inside the rotary plug. Further, a showerhead using the centrifugal water spray structure is provided.
