Abstract: A spray-head assembly includes a pipe structure and a valve-spool. The pipe structure includes a liquid inlet, a flow pathway, and a valve-port. The flow pathway includes an air-flow pathway arranged obliquely with respect to a central axis of the liquid inlet. A bottom end of the air-flow pathway communicates with the liquid inlet. The valve-port is arranged at a top end of the air-flow pathway. The valve-spool is arranged in the flow pathway and configured to control opening and closing of the valve-port.
