Membrane filtration assembly, composite filter element and water purifier system

Abstract

The invention relates to a membrane filtration assembly, a composite filtration core and a water purifier system; the membrane filtration assembly comprises a membrane filtration layer and a membranerolling center pipe, the membrane rolling center pipe comprises a first sealing end cover, a rear filtration core and a center pipe section, the rear filtration core is a tubular structure, and the rear filtration core is communicated with the center pipe section; the first sealing end cover is sealed at the end, away from the central pipe section, of the rear filter element, the membrane filter layer is arranged on the rolled membrane central pipe in a sleeving mode, a flow guide groove is formed in the position, covered with the membrane filter layer, of the peripheral face of the central pipe section, and liquid in the flow guide groove can flow into the rear filter element. While the integration degree is high, the filtering effect is improved, and the core replacement cost is reduced.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a membrane filter assembly, a composite filter element and a water purifier system. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of drinking water. Water purifiers are water purification equipment that can filter tap water to improve water quality. The volume, filtration effect and cost of a water purifier are important factors to measure its market competitiveness. In order to realize the miniaturization of the volume, the research and development personnel are committed to integrating the multi-stage filter element together, and the influence on the filtering effect needs to be considered while the integration degree is increased. When the integration degree is high in the limited space in the filter bottle, if the coordination between the filter elements at all levels is...
