  • Publication number: 20190184409
    Abstract: A shower head structure includes a main body, a face plate, and a switching device installed inside the main body for controlling an outflow of water from the face plate. The circumferential portion of the face plate is provided with a plurality of water outlet units. Each water outlet unit includes a plurality of jet orifices. The water flowing from the plurality of jet orifices forms a bunched spout. The bunched spout includes a plurality of fine spouts. The water won't spray about. Since the diameter of the jet orifice is small, the force of the fine spouts is stronger. The water-saving effect is good. The shower head can be used for low pressure environment.
