Seven apertures in human head ultrafiltration filtration membrane , ultrafiltration filter and ultrafiltration water purifier

An embodiment of the utility model provides a seven apertures in human head ultrafiltration filtration membrane, ultrafiltration filter and ultrafiltration water purifier, wherein, seven apertures in the human head ultrafiltration filtration membrane appearance is circular tubulose, follows seven apertures in the human head ultrafiltration filtration membrane length direction opens has seven through -holes, and wherein, every through -hole is outside to by interior: the integrated into one piece structure of filter layer, supporting layer and exterior cortex, the filter layer includes a plurality of filtration micropores for thereby filter to acquire to the raw water and purify waste water, and on the supporting layer with aperture on the outward appearance cortex all is greater than filter mipor aperture, be used for discharging purify waste water. Above -mentioned technical scheme has following beneficial effect: unique seven apertures in the human head membrane is difficult for disconnected silk, has guaranteed the intensity of milipore filter silk, makes the water purifier that adopts this seven apertures in the human head ultrafiltration filtration membrane can provide the high grade safe drinking water for a long time.
