[0002] As people's requirements for drinking water quality increase, water purifier technology continues to develop to provide people with purer and healthier water. Hydrogen-rich water purifiers, as a type of water treatment equipment, use electrolysis technology to decompose water molecules into hydrogen and oxygen, thereby dissolving a high concentration of hydrogen molecules in the water to generate hydrogen-rich water. Hydrogen-rich water purifiers are usually equipped with intelligent control systems, which can conveniently monitor water quality and equipment status, making them an ideal choice for consumers who pursue a healthy lifestyle.

[0003] However, current technologies have not yet been able to directly link the generation of hydrogen-rich water to the entire home's water system. This means that, despite the many potential health benefits of hydrogen-rich water, current home water treatment equipment cannot extend these benefits to every tap and water outlet in the home. As a result, family members still only have access to ordinary tap water when using water in the kitchen, bathroom, or other places, and cannot enjoy the additional benefits of hydrogen-rich water, which limits the widespread application of hydrogen-rich water in the home.
