Artificial hot spring system

The invention discloses an artificial hot spring system which comprises a filter box, a mineralization box, a disinfection and sterilization box and a heat exchange box which are sequentially arrangedand connected through a pipeline. The filter box is provided with a raw water inlet, and the heat exchange box is provided with a hot spring water outlet. The heat exchange box is provided with a heat exchange pipe of a snake-shaped structure; multiple strip-shaped protrusions are arranged on the outer wall of the heat exchange pipe, so that the heat exchange area is larger, and the heat exchangeefficiency is improved; a pressure regulating device is arranged at the top of the heat exchange box; when the pressure in the heat exchange box is increased, air flow enters the pressure regulatingcavity from the air pipe to extrude the piston, the piston moves, and the pressure relief hole is opened for pressure relief; when the heat exchange pressure is normal, the piston is reset under the action of the spring, and th
