Description
Technical field
The present invention relates to a kind of water filtering device, relate in particular to a kind of more water filtering device of renew cartridge of being convenient to.
Background technology
Employing hydrotreater of the prior art in water and hydraulic pipeline cause that impurity etc. carries out depth-type filtration, has protected user's health preferably.And hydrotreater of the prior art adopts two kinds of filter core patterns conventionally, a kind of is open filter gall: entery and delivery port is all located on filtration channel, the housing of putting into the cylindrical filter gall of hollow is tightened on filtration channel and forms and seal filter core, current are entered by cylindrical filtering layer outside, by being flowed out by filtration channel delivery port after filtering layer by top filtration passage again.And between each filter core, be to connect with threaded connector by the spiral shell mosquito on each filtration channel.Another kind is closed and butted filter core: current are entered after filtering layer is processed and by top delivery port, flowed out by the mouth of a river, filter core bottom.Yet along with the popularization of hydrotreater, they have also progressively come out in defect and the deficiency of application aspect.For open filter core, conventionally in the cylindrical filter gall of hollow, put into the various granular filter materials such as activated carbon, because current in filter core are different from the time of contact of filtering layer filtrate, the effect that process current on filtering layer top is poor, causes handled water quality inhomogeneous stable.Because housing is tightened on filtration channel, therefore can not adopt many mouths of a river filter core pattern to improve filter effect.While manufacturing assembling, the spiral shell mosquito junction of filtration channel easily leaks.Because thread connecting mode can only be that single channel pipeline connects, the rear and front end that entery and delivery port is positioned at water purifier is caused and is used constant and affect attractive in appearance.In use procedure, replacing filter gall is relatively required great effort and need to be used special spanner.And for closed and butted formula filter core, although filtering layer treatment effect better more renew cartridge more bother, need specialized maintenance personnel to make house calls, corresponding increase manpower, financial resources expenditure.In addition, in use for some time, being stopped up gradually by impurity or adsorbing of filter core filtrate causes filtration, adsorption effect obviously to decline to filter core.And, along with the impurity that filter core is retained down is more and more, tend to make " pollution " degree of this filter core impurity to surpass " pollution " degree of drinking water itself, thereby make filter core become new " pollution " source.The filter element of water purifier that particularly adopts milipore filter, NF membrane, reverse osmosis membrane at some, because mesh size is few, is easy to produce clogging during use, affect filter element life.And that two mouth of a river filter cores are arranged to multi-filtering layer combination is more difficult, especially the hydrotreater for two ends screen cloth type filtrate, intermediate particle filtrate pattern adopts the very difficult impurity that middle and infiltration is deposited in to rear class screen cloth of contrary omnidistance backwash mode by thorough by water inlet discharge after multi-stage filter core, usually occurs that interstitial impurity is by the forward and reverse phenomenon that the row of flushing does not go out back and forth; And have layering or classification separately the hydrotreater of " recoil " function both needed water (flow) direction to switch, more need to configure corresponding multi-filtering layer and many mouths of a river filter core.It has caused very large impact to the structure of conventional filter core and installation replacing pattern again conversely.
Summary of the invention
Object of the present invention provides a kind of more water filtering device of renew cartridge of being convenient to regard to being in order to address the above problem.
