▎ 摘　　要

NOVELTY - The device has a storage tank (100) in which water to be purified is stored. A manual actuator (200) pumps the water contained in the storage tank using a hand or foot. A pre-filter (300) filters foreign substances by flowing in the water supplied under pressure by the actuator. An ultra-filtration filter (400) is connected to an outlet of the pre filter to filter bacteria and viruses, and contains graphene-based nanomaterial. Multiple cylindrical bodies with a predetermined diameter are arranged at a distance from each other at a front or a rear end of the automatic actuator to filter out particulate matter. A detachable separator (500) has an enclosure with an inlet port on one side and a discharge port on another side. An inner box is installed inside the enclosure. A space dividing plate is formed at one end adjacent to the discharge port. A water purifier is stacked in a multi-layered structure. USE - The non-powered passive drinking water purifying device is useful for supplying safe water to small communities desperately needed in underdeveloped countries, and allowing users to pump water by moving their hands or feet. ADVANTAGE - The device supplies drinking water for households or small-scale communities in areas where electricity is not available or where electricity supply is not stable, so that drinking water can be safely drunk.
