Working principle of jacuzzi

The massage bathtub is mainly moved by a motor, so that the spray nozzle on the inner wall of the bathtub sprays water mixed with air, which causes the circulation of the water, thereby generating massage effect on the human body. Take Kohler's single-speed water pump and pneumatic switch massage bathtub as an example: as long as the bathtub is filled with water, it can run on its own. There is a suction port at the bottom of the bathtub, and the water is sucked from here to the pump, and then flows back to the bathtub through the nozzles installed on both sides of the bathtub. At this time, air is sucked in from the air inlet and mixed with the water flow at the nozzles. By rotating the edge of each nozzle, the air flow can be adjusted.
