Abstract:
1. A multifunctional spa device, comprising: a pump disposed with a water tub to generate a pressurized water-air mixture for water contained in the water tub; a vent pipe coupled to an inlet of the pump controlled by a circuit; an intake pipe extending from the pump into the water contained in the water tub for guiding the water into the pump; and, a jet assembly coupled to an outlet of the pump by an intermediate pipe portion, the jet assembly generating a turbulent action upon the pressurized water-air mixture expelled from the pump drawing water flow and air therein through the intake pipe and vent pipe; a flow limiting valve mechanism connected inline to the vent pipe for controlling air flow into the pump prior to mixing of the water-air mixture output from the pump, thereby controlling the pressure of the water flow output from the pump; wherein the jet assembly includes an outlet disk portion extending diametrically outward beyond the intermediate pipe portion to form therefor a diametrically expanded termination, the outlet disk portion having a plurality of pores collectively arranged peripherally about the intermediate pipe portion for diametrically dispersed passage of the pressurized water-air mixture received therefrom; a vacuum being formed thereby at a local region behind the pores when a high pressure water flow passes through the pores to eject a water column of microbubbles.
