The invention discloses a magnetization treatment method and device thereof for coil tube type fluid, consisting of a fluid coil tube, magnetization treatment component, joints and an ornamental box. Both ends of the fluid coil tube are respectively connected with inner holes of the inflow fluid joints and outflow fluid joints through rapid connectors, threads and adhesion, etc., the positive pole and the negative pole of a magnet block are respectively face toward fluid pipes and arranged at the side of the coil tube. The invention is of simple structure, and can increase the flowing distance, decrease the volume, save magnetization treatment material, and has the high production effect by using standardized parts to be assembled, thus greatly cutting down the production cost, facilitating mass production, and having best anti-scaling and scale removing and energy conservation effect. The invention is especially applied to the anti-scaling, scale removing and oxygen enhanced treatment places of electrical heating tanks, public drinking-water tanks, the drinking machine of bulk held water, etc.

The public herb boiler using solar energy and electrical energy has the advantages that structure is simple, installation is easy, the herb boiler can be used to boil herbs to prevent public epidemic disease transmission as well as be used as a public drinking water device, and the herb boiler is suitable for current hygienic environment of China.

The embodiment of the invention provides drinking water supply equipment, method and system, and belongs to the technical field of public drinking water supply. The equipment comprises a terminal control device and a water obtaining device. A first movable plate for opening and closing a water obtaining part is arranged on the water obtaining part of the water obtaining device, and a second movable plate for opening and closing a water obtaining opening is arranged in the water obtaining part. When the first movable plate of the water obtaining device makes the water obtaining part in a closed state, the terminal control device controls the second movable plate to move so as to make the water obtaining opening in an open state due to the movement of the second movable plate. Furthermore, the terminal control device controls the water obtaining device to release drinking water from the water obtaining opening according to a preset control program. When the drinking water is released by the water obtaining opening, the first movable plate makes the water obtaining part in the closed state, so that the internal environment during water obtaining is isolated from the external environment, and then the safety and sanitation of safe public drinking water equipment during use are effectively ensured.
