After a day of hard work, your body is tired. You want to find a way to relieve your body and mind. At this time, we will take a hot bath. The water temperature can speed up the blood circulation. The SPA bathtub has the best effect on eliminating fatigue. But do you know the working principle of SPA bathtubs? This article will give you a detailed understanding.

SPA bathtub is different from ordinary bathtub. It is a kind of household appliance. It is a luxury electrical appliance. It is consists of two parts. That is cylinder body and massage system. The cylinder body part is a bathtub of various shapes. It is made of steel or acrylic. The massage system consists of the nozzle in the cylinder and the hidden pipes, motors, control boxes behind the bathtub. This massage system is the key to buying SPA bathtub. It is the part that most people know little about.

We can divide the bathtub massage method into vortex massage, bubble massage and mixed massage.

Vortex massage uses the traditional hydraulic massage method. The powerful nozzle ejects water and air from the bathtub. It produces double effects. It has remarkable effects on blood circulation, lymphoid tissue and waste discharge. The vortex generated in this way can massage the whole body. In addition, the high-water mute adjustable nozzle has a pressure of 18psi. The air switch is fully opened, and the nozzle water output is 14gpm. It can produce about 10,000 small bubbles. Smaller bubbles are not easy to quickly float to the water surface and burst. So the water flow from the nozzle is strong but very soft. We can open it from the front to clean the inside of the nozzle.

Double helix massage nozzle has unique swirling bubble. It has continuous vortex effect. The air and water flow in the same direction as the rotation are produced. The deep massage force is transmitted. It can relax tense muscles and relieve pressure.

Bubble massage: the system uses a bubble pump to pass through the bubble nozzle at the bottom of the bathtub. It is to generate a large number of bubbles. It can wrap the whole body. Gently touching the body can make the spine and neck comfortable.

Many bathtubs on the market have nozzles at the bottom. But they do not have the function of bubble massage. The reasons are: 1. They are not equipped with bubble pumps.So they do not have the function of bubble massage. 2. The nozzle at the bottom of the nozzle connects with the water pump. It ejects water flow and cannot relax the body. The pipes connecting the bottom nozzle and the water pump are lower than the water suction port. So the accumulated water in these pipes cannot be removed at all.

Mixed massage combines vortex massage and air massage into one. Vortex nozzles can promote blood circulation. The air type can produce the effects of ozone and fountains. Don't drop bath essence or aromatic oil in the water when using the bathtub. Otherwise, we cannot remove oil stain layer on the pipeline or nozzle.
