The nano-cup adopts the latest silver-based nano-materials, and the nano-materials are coated on the inner layer of the cup liner through a unique process. The unique far infrared and negative ion functions of silver-based nanomaterials give the nano-functional cup a unique health care function. Make elastic water into small molecular active water, enhance the ability of water infiltration and cell exchange, accelerate the outward excretion of waste in human body, and maintain the healthy state of human body; Improve human microcirculation system, enhance blood circulation, dilate hair blood vessels, accelerate human metabolism and improve human immunity; Activate human cell tissue, make old cells metabolize and give them regeneration ability, enhance cell energy and maintain cell function and vitality; Adjust the taste of water quality, the active water of small molecular groups is broken and recombined, and the odor in the water is removed, so that the taste of water quality is sweet and mellow; Antibacterial function: The negative ions in silver-based nanomaterials have high activity and strong redox effect, which can destroy the activity of active enzymes in bacterial cell membrane or cell protoplasm, thus achieving the purpose of antibacterial and bacteriostatic.
