Description
Technical field
The present invention is relevant with water treatment field, is specifically related to depth-type filtration, the purification aspect of drinking water.
Background technology
At present, water purifier uses more universal at home.Adopt water purifier in water and hydraulic pipeline cause that impurity etc. carries out depth-type filtration, has protected user's health preferably.But, water purifier has also progressively come out in defect and the deficiency of application aspect: for the water purifier that adopts sealing filter gall, although the labour intensity of handling is less, often needs to open cabinet cumbersome, and the housing of sealing filter gall is to bear 4kg/cm
2tap water hydraulic, therefore manufacturing cost is higher and reclaim very difficult again.In, low price water purifier mostly adopts open inner bag configuration bare machine pattern.The filter housing of built-in inner bag is lifted on the machine construction of support below, although filter cylinder can be reused, the inside and outside hydraulic pressure of Simple sealed housing that built-in filter gall is used is consistent or approaching, filter housing only plays buffer action therefore cost is extremely low, and can directly reduce filter gall cost 20% left and right, but also the corresponding inner bag that brings is changed the difficult problems such as difficulty.The filter housing that common water purifier is placed built-in filter gall is directly placed in kitchen cabinet, in the time changing inner bag, water purifier need to be taken out, make somebody a mere figurehead, special filter gall spanner is from bottom to top enclosed within on filter housing, the rotation of exerting oneself just can be become flexible filter housing and be pulled down filter housing with being threaded of support again.After more renewing inner bag, firmly the filter housing of built-in filter gall is tightened in to support below, whole operating process is very painstaking again.Owing to having, the water purifier of water is very heavy, and involved by water-in and water-out flexible pipe, is difficult to operation, and time-consuming not the saying of requiring great effort also needs to use special spanner.And, because inner bag is serially connected in water purifier, careless slightlyly when replacing be easy to occur drainage.Because the seal of the built-in filter gall of existing flat mouth is arranged on the upper/lower terminal of built-in filter gall, the filter housing that is lifted on support below is not slightly tightened, the filter material layer of built-in filter gall will be by " short circuit ": running water directly flow to delivery port by water inlet without filter material layer, and all these operate with sense, and very painstaking.Therefore, in the time that changing filter gall, needs all to contact house calls by appointment with specialized maintenance personnel, the extraneous expenses such as manpower, financial resources and the transport cost of the professional sales service of corresponding increase company.These extra correlative charges that occur are finally transferred to it consumer in the lump.Change and be accompanied by the overall process that water purifier uses always in view of filter gall, change the time interval at every turn conventionally about six months to 1 year.The relevant issues of being drawn by replacing filter gall are appearance repeatedly often, and being consequently acknowledged as water purifier is difficult to one of universal Three Difficult Issues.Although the water purifier that adopts disjunctor filter cylinder and above put forward filter gall pattern can solve the problem of changing built-in filter gall, and the advantage such as raising machine assembly quality and efficiency, brought the disjunctor cartridge structure complexity of water purifier simultaneously;
