Abstract
The application discloses a membrane element, a filter core and a water purifying device, and relates to the technical field of water purifying devices. The membrane element comprises a water collecting pipe, a first membrane unit and a second membrane unit which are wound around the periphery of the water collecting pipe, the first membrane unit comprises a first water inlet for guiding raw water into the first membrane unit, a first water outlet and a second water outlet for guiding waste water, and a first pure water outlet for guiding pure water, the second membrane unit comprises a second water inlet which is connected with the second water outlet, a third water outlet for guiding waste water, and a second pure water outlet for guiding pure water, and water flowing out of the second water outlet enters the second membrane unit through the second water inlet and then flows out of the third water outlet. The service life of the membrane element is improved by optimizing the flow channel of the membrane element.
