Multi-functional rotary switching type shower head

Abstract

This utility model relates to a multifunctional rotary switching nozzle, including an inner water outlet pipe, an outer rotating pipe, and multiple water spraying components. The outer rotating pipe has a through hole in its center and multiple water-passing chambers arranged annularly along the axis of the through hole. Multiple water spraying components are mounted on the outer circumference of the outer rotating pipe and correspond to the multiple water-passing chambers. A first water-passing hole (one or more) is formed between the water-passing chamber and the through hole. A first water-inlet hole (one or more) is formed on the side wall of the inner water outlet pipe. The outer rotating pipe rotates around the axis of the inner water outlet pipe, and the rotation causes the first water-inlet hole to correspond one-to-one with and connect to the first water-passing hole of any water-passing chamber. A second water-passing hole is provided on the outward-facing side of each water-passing chamber and is connected to the water inlet end of each water spraying component. By rotating the outer rotating pipe, the first water-passing hole of any water-passing chamber corresponds to the first water inlet hole of the inner water outlet pipe, thus enabling the corresponding water spraying component to spray water.
