  • Patent number: 11369981
    Abstract: A water outflow control assembly includes a water inlet body, a push rod, a rotor and an elastic member. The water inlet body is provided with a valve cavity. One end of the valve cavity is provided with a push rod hole for sliding of the push rod. The push rod is provided with push blocks. The rotor is provided with tooth blocks extending toward the push rod hole and matching with the push blocks, and a retaining wall with a gap. The retaining wall is in clearance fit with an inner wall of the valve cavity, and rotation of the rotor changes a degree that the retaining wall blocks a water inlet channel.

  • Patent number: 10478838
    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.
