Jacuzzi is generally considered to be a kind of sanitary equipment. People want to buy it, and go to the bathroom shop to decorate. No one has seen it in the electronics store. In fact, the jacuzzi is different from a normal bathtub. It is a kind of household appliance, a kind of luxury electrical equipment. The Jacuzzi consists of two main components, a cylinder and a massage system. The whirlpool is mainly driven by the motor, so that the nozzle on the inner wall of the bathtub ejects the water mixed into the air, causing the circulation of the water to generate a massage effect on the human body. Take the Kobiabath single-speed water pump and the pneumatic bathtub of the pneumatic switch as an example: as long as the bathtub is filled with water, it can be self-sufficient. There is a suction port at the bottom of the bathtub, from which the water is sucked to the water pump, and then flows back to the bathtub through the nozzles installed on both sides of the bathtub. At this time, the air is sucked in from the air inlet and mixed with the water flow at the nozzle, and the edge of each nozzle is rotated to adjust the air flow. 
The cylinder part is nothing more than a bathtub of various shapes, the material is mostly steel or acrylic; and the massage system has the nozzles visible in the cylinder and the pipes, motors and control boxes hidden behind the bathtub. This massage system is the key to buying a jacuzzi, and it is also a part of the average person who knows about the jacuzzi.
