A shower head water-saving switching structure, comprising a water inlet seat having a water inlet passage, a water discharging body having a plurality of functional water chambers, a functional water switching member, a flow switching member, and a drive mechanism;
- a water distribution chamber being formed between the water inlet seat and the water discharging body, the water distribution chamber being provided with a side water inlet communicating with the water inlet passage;
- an inner bottom wall of the water distribution chamber being provided with a plurality of functional water chamber water inlets communicating with the respective functional water chambers;
- the drive mechanism including a ratchet wheel that is rotatably fitted on a top surface of the water inlet seat, a push rod that is movably fitted on the top surface of the water inlet seat, and a button that is movably fitted on the water inlet seat;
- the push rod linking and cooperating with the ratchet wheel, a return spring being provided between the push rod and the water inlet seat for moving the push rod to move, the button linking and cooperating with the push rod;
- the functional water switching member including a water distribution gear that is rotatably accommodated in the water distribution chamber;
- the water distribution gear being coaxially connected with the ratchet wheel through a rotating shaft that passes through the water distribution chamber, a bottom surface of the water distribution gear abutting against the inner bottom wall of the water distribution chamber, the water distribution gear being provided with a water distribution opening selectively communicating with one of the functional water chamber water inlets;
- the flow switching member including a drive gear that is rotatably accommodated in the water distribution chamber and a flow limit post, the drive gear being meshed with the water distribution gear, the flow limit post being connected to the drive gear, a side wall of the flow limit post being provided with a flow limit protruding block corresponding to the side water inlet;
- wherein the drive mechanism drives the water distribution gear to rotate, so that the water distribution opening of the water distribution gear selectively communicates with one of the functional water chamber water inlets;
- the water distribution gear drives the drive gear and the flow limit post to rotate, so that an overlapping area of the flow limit protruding block of the flow limit post and the side water inlet is increased or decreased, thereby controlling water flow passing through the side water inlet, wherein the functional water switching member and the flow switching member are both in operative coupling with the drive mechanism such that operation of the drive mechanism drives both the functional water switching member and the flow switching member.
