HOT TUB WALL JET NOZZLE

Abstract

A hot tub wall jet nozzle includes a nozzle body and a nozzle core seat. Water flows from the water inlet into the water flow channel in the nozzle body. Air enters through the air inlet of the nozzle body and reaches the first air accommodating cavity, then flows from the first air accommodating cavity to the second air accommodating cavity, and the air from the second air accommodating cavity is then mixed with the water in the nozzle core seat at the water outlet under the Venturi effect, and the mixed water and air flow is finally discharged through the water outlet. This structural arrangement allows for reduced dilution and loss of air bubbles during water flow transmission. The Venturi effect produced in this nozzle is capable of generating a greater volume of air ejection, thus enhancing the strength and effectiveness of the massage.
