Abstract
A spraying head assembly for a massaging tub includes a housing, a cover, a water outlet valve seat, a water outlet valve cover, a vortex rotor, a bushing, a nozzle, an impulse rotor, and a motor. Thus, the water is pressurized by rotation of the helical blades of the vortex rotor and the helical plates of the water outlet valve seat to produce a strong water beam that is injected outward from the nozzle, thereby enhancing the massaging effect.
