Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings composite filter element 10 according to the embodiment of the present invention is described.
As Figure 1-Figure 5, bottle 100, preprocessing filter element 200 and filter membrane component 300 is comprised according to the composite filter element 10 of the embodiment of the present invention.
Bottle 100 is provided with raw water inlet 110, pre-treatment water outlet 120, supercharging pre-treatment water-in 130, pure water water outlet 140 and condensed water water outlet 150.Preprocessing filter element 200 is located in bottle 100.Filter membrane component 300 is nested in preprocessing filter element 200.
The filter membrane 320 that filter membrane component 300 comprises abdominal cavity header 310 and is wound on abdominal cavity header 310, the upper end of abdominal cavity header 310 is provided with pure water posticum 470 and leads to the upper pre-treatment prosopyle 480 (above-below direction is as shown in the arrow A in accompanying drawing) of filter membrane 320 upper end, the lower end of abdominal cavity header 310 is provided with the lower pre-treatment prosopyle 490 leading to filter membrane 320 lower end, the sidewall of abdominal cavity header 310 is provided with the pure water prosopyle 460 communicated with filter membrane 320, there is in abdominal cavity header 310 the pure water water exit 450 being communicated with pure water prosopyle 460 and pure water posticum 470.
Wherein, preprocessing filter element 200 and filter membrane component 300 are successively set on raw water inlet 110 and between pure water water outlet 140 and condensed water water outlet 150.Particularly, preprocessing filter element 200 is between raw water inlet 110 and pre-treatment water outlet 120, filter membrane component 300 is at supercharging pre-treatment water-in 130 and between pure water water outlet 140 and condensed water water outlet 150, and upper pre-treatment prosopyle 480 is communicated with supercharging pre-treatment water-in 130 with lower pre-treatment prosopyle 490.
Below with reference to the accompanying drawings the Water treatment of the composite filter element 10 according to the embodiment of the present invention is described.Wherein, straight line is former water and pretreated water, and dotted line is pure water, and long and short dash line is condensed water.
As shown in Figure 2, after former water enters composite filter element 10 by raw water inlet 110, first carry out prefilter through preprocessing filter element 200, the pretreated water filtered through pre-treatment is flowed out by pre-treatment water outlet 120, after supercharging, again flow into composite filter element 10 again by supercharging pre-treatment water-in 130.As shown in Figure 5, the pretreated water after supercharging flows to filter membrane 320 by upper pre-treatment prosopyle 480 and lower pre-treatment prosopyle 490.As shown in Figure 3, the pure water after filter membrane 320 filters successively through pure water prosopyle 460, pure water water exit 450, pure water posticum 470 flow out by pure water water outlet 140.As shown in Figure 4, the condensed water after filter membrane 320 filters flows to condensed water water outlet 150 by filter membrane 320 both sides, and is flowed out by condensed water water outlet 150.
According to the composite filter element 10 of the embodiment of the present invention, by preprocessing filter element 200 and filter membrane component 300 are integrated, the multi-stage filter core in existing water cleaning systems can be replaced, so not only can simplify pipeline to connect, conveniently install and change, and joint quantity can be reduced, thus reduce the risk point that leaks.Further, after the integrated preprocessing filter element 200 of composite filter element 10 and filter membrane component 300, preprocessing filter element 200 can be made consistent with the work-ing life of filter membrane component 300, eliminate the frequent inconvenience changing different filter core, significantly reduce use cost.In addition, abdominal cavity header 310 in filter membrane component 300, it is provided with pre-treatment prosopyle 480 and lower pre-treatment prosopyle 490, pretreated water after supercharging can flow to filter membrane 320 by the top and bottom of abdominal cavity header 310 simultaneously filter, water-flowing amount can be increased thus to increase water production rate, meet and namely filter the demand of namely drinking.Therefore, be integrated with multiple Water warfare filter material according to the composite filter element 10 of the embodiment of the present invention, the pipeline that can simplify water cleaning systems connects and installs and change, and the risk point that leaks is few, raising user experience, reduce use cost, and there is large flux, namely filter the i.e. advantage such as drink.
Alternatively, also can not arrange pre-treatment water outlet 120 and supercharging pre-treatment water-in 130 according on the bottle 100 of the composite filter element 10 of the embodiment of the present invention, the pretreated water after preprocessing filter element 200 is filtered directly can enter filter membrane 320 by upper pre-treatment prosopyle 480 and lower pre-treatment prosopyle 490.
