AI Technical Summary
The uneven distribution of water flow path in the existing filter cartridge structure leads to low filter media utilization, excessive saturation in the central area causing premature clogging, and underutilization of the edge area, resulting in filter media waste and shortened filter cartridge life.
By adopting a flow guide plate structure, flow guide plates are set between the filter media and the inlet. The radial gradient expansion of the flow guide hole design establishes differentiated water flow resistance, forming a water channel design with high resistance in the center to reduce flow and low resistance at the edge to increase flow, thus achieving a balanced distribution of water flow in the cross section of the filter media layer.
It improves the utilization rate of filter media, extends the service life of filter elements, and increases filtration efficiency.
