Preparation device of water rich in active hydrogen

The utility model discloses a preparation device of water rich in active hydrogen, which relates to the technical field of hydrogen-rich water and comprises a sealing barrel, a sealing mechanism is arranged on the upper portion of the sealing barrel, and the sealing mechanism comprises a cover plate. A pressure reducing mechanism is arranged outside the sealing barrel, a sliding plate is slidably connected to the inner wall of the sealing barrel, a sliding rod is fixedly connected to the upper surface of the sliding plate, and a telescopic rod is fixedly connected to the upper surface of the cover plate. Water is heated through the heating pipe, the air pressure in the sealing barrel is reduced through the pressure reducing mechanism, various water-soluble gases in the water are emitted through low air pressure and high temperature, and the air at the lower part is extruded through the sliding plate, so that the air emitted from the water flows to the outside through the sliding rod; the effect of discharging
