Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

Please refer to the accompanying drawings, embodiments of the present invention include:

An integrated high-efficiency water filter element, including a top cover 2 and a casing 1, the top cover 2 is located on the top of the casing 1; the center of the top cover 2 is provided with a raw water inlet 3, and the raw water inlet Backwash water outlets 13 are evenly distributed around the water outlet 3; the lower bottom of the housing 1 is connected with a water outlet pipe 11, and the water outlet pipe 11 is provided with a water pipe connection valve 12, which can be used according to the specifications of the actual water purifier. The water pipe connection valve connects the water pipe of required length on the water outlet pipe.

The interior of the housing 1 is sequentially installed with a filter screen 5, a first filter layer 6, a second filter layer 7, a permeable support frame 8, a filter membrane layer 9 and a distribution plate 10 from top to bottom. A first water storage bin 41 is formed between the lower edge of the top cover 2, a second water storage bin 42 is formed between the lower edge of the permeable support frame 8 and the filter membrane layer 9, and the lower edge of the membrane separation layer 9 and A third water storage bin 43 is formed between the upper edge of the diverter plate 10 , and a fourth water storage bin 44 is formed between the lower edge of the diverter plate 10 and the inner bottom of the housing 1 , and the water storage bins are used for temporarily storing filtered water.

The filter screen 5, the first filter layer 6 and the second filter layer 7 are sequentially superimposed and fixedly placed on the permeable support frame 8, the first filter layer 6 is a quartz sand filter layer 61, and the quartz sand is tiled Placed in the water-permeable sand container 62, the second filter layer 7 is a mixed sand filter layer, and the mixed sand 71 is laid flat in the water-permeable sand container 72; the raw water entering the water filter element passes through the filter screen in turn , quartz sand, mixed sand and filter membrane to remove various particles, bacteria, microorganisms and other impurities.

The distribution plate 10 is a solid plastic plate fixed in the housing 1 , and a plurality of evenly distributed through holes 14 are opened in the distribution plate 10 . The water that has been filtered to remove impurities at all levels flows into the fourth water storage bin through the aperture on the diverter plate, and flows into other parts of the water purifier through the outlet pipe for treatment.
