Abstract

A combination showerhead with dial button switching includes a fixing seat, two shower heads and a switch mechanism. The fixing seat has an inlet waterway and at least two diversion waterways. The switch mechanism includes a water diversion plate, a valve spool, a dial button and an elastic body. The water diversion plate is movably connected to the fixing seat and coupled to the inlet waterway and the diversion waterways, so that the plate rotates in a preset angle to switch the waterways. The valve spool is connected to the fixing seat and to the water diversion plate, so that the valve spool slides to drive the water diversion plate to rotate in a preset angle. The dial button has a cam portion and is rotatably connected to the fixing seat. The valve spool abuts against the periphery surface of the cam portion. The elastic body resets the valve spool.
