  • Publication number: 20200087177
    Abstract: A hydrogen gas generator, a hydrogen gas tank, and an aspirator are unitized into a one-unit configuration. Hydrogen gas generated by the hydrogen gas generator is mixed with a water stream, e.g., tap water without resorting to external power, using hydrogen gas produced in large amounts by a hydrogen gas generator, allowing to always supply hydrogen-containing water, e.g., tap water, to water users on need. The aspirator includes a nozzle part that increases the speed of the tap water flowing in a water conduit pipe, creating a lower pressure state below the pressure of the hydrogen gas tank by the Venturi effect and lowering the flow pressure of tap water to suck hydrogen gas into the flow of the tap water, thereby producing hydrogen-contained tap water is produced.

  • Patent number: 10207232
    Abstract: A dissolved hydrogen liquid-discharging pot makes it easier for a user to use hydrogen water by making the pot capable of discharging or spraying a liquid in which hydrogen is dissolved continuously for a constant period at a prescribed pressure. The internal pressure of a pressure chamber, the volume of which has been subdivided by an indicator line on a pot body, is maintained with hydrogen, which is generated by a hydrogen-generating agent disposed in a hydrogen-generating section, at a discharge pressure that is sufficient to discharge all of the liquid inside a bottle section while an on-off valve that opens and closes a discharge tube is closed, and when the on-off valve is opened intermittently or continuously, at a pressure sufficient for continuing discharge of the liquid inside the bottle section and performing continuous discharge of dissolved hydrogen liquid until the bottom of the bottle section is reached.
