  • Publication number: 20190336987
    Abstract: A shower head with an inner core includes a shower head body, an inlet valve core assembly, an inner core assembly, and a water outlet panel. The inlet valve core assembly is fitted in an inlet valve chamber of the shower head body. A return spring of the inlet valve core assembly abuts against an inner wall of the inlet valve chamber and one end of an inlet valve core. The inner core assembly is detachably fitted inside an inner core chamber. The water outlet panel is connected with the shower head body and provided with a functional water chamber communicating with a water outlet passage. The shower head can prevent the inner core assembly from flying out of the inner core chamber due to the impact of the water flow to hurt the user.

  • 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.

  • Patent number: 10005090
    Abstract: A shower head structure includes a housing and a panel. A middle of the panel is provided with a guide valve. A first functional water chamber is formed between the guide valve and the housing. An upper part of the guide valve is formed with a water inlet chamber. A lower part of the guide valve is formed with at least one second functional water chamber. A middle portion of the guide valve is formed with a water inlet, a first water discharge passage, and a second water discharge passage. A rotary shaft is provided in the accommodation chamber. Another end of the rotary shaft extends outward to form an eccentric connecting rod. The eccentric connecting rod is connected with a piston which controls the water intensity of the first functional water chamber.
