Description
Technical Field
The application relates to the field of water purification, in particular to an integrated filter element assembly.
Background
The filter element is generally connected with the disposable filter element quickly, is sanitary and safe, and is convenient to replace. But cannot meet the design requirements of small and compact installation in a water purifier. In particular to a water purifier with a built-in water storage tank, the inside of the water purifier comprises: a water storage tank, various large-flux filter elements and a control connecting piece. Thus, the volume is too large to meet the requirements of the general household kitchen. For some composite cartridges, it is desirable to be placed in a cartridge within the water purifier housing. When the filter element is to be replaced, a large amount of sticky matters, silt and other pollutants are adhered to the inner wall of the filter cylinder, so that the filter element is difficult to treat and secondary pollution is easy to form. The disposable integrated filter element assembly which integrates all the filter elements together has the average service life of the pre-filter element of 6-12 months, the average service life of the filter membrane of 24-30 months, unnecessary waste is easily caused by early replacement, and the water purifying effect is easily reduced by delayed replacement.
When the filter element is replaced, for example, the PP cotton and/or the activated carbon filter element is replaced, liquid retained in the cavity of the filter element can flow out due to the internal structure, and inconvenience is brought to replacing the filter element.
Activated carbon is often adopted in the filter element of the water purifier to adsorb the abnormal odor in water, so that the taste is improved, and the adsorption effect of the sintered carbon rod is optimal. However, the sintered carbon rod has fine pores, is extremely easy to block, and has too short service life. In addition, because the pipeline system of the water purifier has gas for various reasons, the filter element becomes a gas enrichment area for the reasons of the cavity containing structure, the effective filtering area of the filter element is gradually reduced, the liquid flow is disturbed, and the resonance hidden trouble exists.
For the intelligent water purifier which adopts the ultra-low pressure reverse osmosis membrane or the ultra-low pressure nanofiltration membrane and is not driven by a pump, the high concentrated water has high corrosion effect, and the damage of a measurement and control device (such as a pressure measuring device) arranged in the membrane shell or in the concentrated water discharge area is extremely easy to cause. Thereby destabilizing the measurement basis data.
These problems require us to redesign a filter cartridge to solve the above problems.
