Perhaps at least a portion is flowed out by the fluid that import 103 is flowed into housing 101 via fluid bypass passageway 111 from outlet 105.
Specifically, housing 101 includes lid 113 and cavity 115, which is connected through a screw thread with cavity 115
117 are mutually coupled, to form substantially closed sealed chamber, i.e. filter chamber 107.It is threadedly coupled at 117 and is additionally provided with sealing ring
119, it is used to further improve the sealing performance between lid 113 and cavity 115, to avoid fluid from its gap location stream
Go out.
Mixing chamber 118 is further included on lid 113, which has two imports 118a, 118b (i.e., in upstream end
Correspond respectively to the outlet of fluid bypass passageway 111 and the outlet of filter chamber 107), receive come from fluid bypass passageway 111 respectively
Unfiltered fluid and the fluid filtered from filter chamber 107, the mixing chamber 118 there is outlet 118c to permit in downstream
Perhaps mixed fluid outflow.
In this embodiment, filter chamber 107 is cylindrical in shape.Correspondingly, the filter core 109 accommodated in filter chamber 107 also be in and mistake
The sleeve-shaped that 107 shape of filter chamber is adapted.In other examples, filter core 109 can also be in filter membrane, strainer shape or other be adapted to
Shape.115 bottom of end thereof contacts cavity of the filter core 109, and the other end of filter core 109 then contacts the bottom of lid 113, from
And make it that filter core 109 is clamped and is fixed in filter chamber 107.It is provided with lid 113 in import 103, outlet 105, first
Between 121 and second middle perforate 123 of perforate；Wherein, which fluidly connects with import 103, and second
Middle opening 123 is fluidly connected with outlet 105, so that the filter chamber 107 limited jointly by lid 113 and cavity 115
Import 103 is fluidly communicated to via the first middle perforate 121, and outlet is fluidly communicated to via the second middle perforate 123
105。
In one embodiment, filter core 109 is ion exchange resin filter core, it is with ion-exchange capacity, suitable for filtering
Calcium and magnesium ion in water or other be easily formed the ion of incrustation scale.In some other examples, filter core 109 can also be by it
The filter element that he is filtered in a manner of physically or chemically substitutes, and further, which can be housed in filter cylinder
It is interior.
In the embodiment shown in fig. 1, fluid bypass passageway 111 is arranged in lid 113, it passes through in lid 113
Through hole or pipeline come connect import 103 with outlet 105.In some other examples, fluid bypass passageway 111 can also be by
The other positions of housing 101 are arranged on, such as are arranged in filter chamber 107.For example, the length of filter core 109 can be slightly less than
The spacing of 113 bottom of lid and 115 bottom of cavity, or 109 certain one end of filter core subregion not with 113 bottom of lid or
115 bottom of cavity completely attaches to so that left in filter chamber 107 cannot effective impurity screening notch, notch composition
So that the fluid bypass passageway 111 of fluid section bypass.
As can be seen that for flowing into the fluid in housing 101 by import 103, one part can be with via passing through filtering
Housing 101 is flowed through in the first fluid flowing path 11 of chamber 107, and is flowed out at outlet 105；And another part then can be via logical
Housing 101 is flowed through in the second fluid flowing path 12 for crossing fluid bypass passageway 111, and is flowed out at outlet 105.
Specifically, for the fluid flowed with first fluid flowing path 11, it can be filtered by filter core 109 and effectively go
Except impurity substances therein, therefore, which is alternatively referred to as fluid filtering passage.In the implementation
In example, the first middle 121 and second middle perforate 123 of perforate is respectively provided in the inside and outside of sleeve-shaped filter core 109.
In this way, having to flow through filter core 109 via the fluid that first fluid flowing path 11 is flowed, this is conducive to filter core 109 to fluid
Filtration.
On the other hand, due in fluid bypass passageway 111 and being not provided with filter core 109 or other similar filter elements,
Thus for the fluid flowed with second fluid flowing path 12, it will not be filtered, thus impurity substances therein, particularly
Some mineral ions that must be not necessarily filtered out, such as calcium and magnesium ion, still are able to be retained in the fluid after being processed.
In this way, it is less than from impurity to be filtered (such as calcium and magnesium ion) concentration in the fluid of the outflow of outlet 105 in the fluid of import 103
Impurity concentration to be filtered, but be greater than from filter core 109 flow out fluid in impurity concentration to be filtered, therefore, in general,
Particular value can be adjusted by the concentration of the impurity to be filtered in the fluid of 100 purified treatment of fluid purification, with full
The needs of sufficient practical application.
It is appreciated that the impurity substances concentration in fluid after being handled by fluid purification 100 depends significantly on unit
The volume of the fluid flowed in time with second fluid flowing path 12 with first fluid with flowing path 11 and second fluid stream
The ratio of the cumulative volume for the fluid that dynamic path 12 is flowed, namely the bypass rate of fluid bypass passageway 111.In practical applications, may be used
To change the minimum-value aperture of fluid bypass passageway 111, or change the length of the fluid bypass passageway 111 to change with second
The fluid flow rate (or flow) that body flow path 12 flows, so as to adjust the ratio of two parts fluid, and then changes by outlet 105
The impurity concentration of the fluid of outflow.In fluid purification 100 as shown in Figure 1, the aperture quilt of the fluid bypass passageway 111
It is configured to from this segment fluid flow that the fluid bypass passageway 111 flows out and after the part fluid mixing that filter chamber 107 flows out
Fluid impurity concentration within preset range so as not to produce be similar to incrustation scale similar to deposit.For this area
For technical staff, when he or she know the structure of filter chamber and cannot produce incrustation scale similar to deposit restrictive condition after,
He or she can just be readily derived diameter range of the fluid bypass passageway 111 in most thin place without excessive experiment.Moreover,
Those skilled in the art can also be designed fluid bypass passageway 111 according to each regional water quality situation (hard or soft),
Therefore the fluid bypass passageway 111 because area difference can be different.
As can be seen that since the impurity substances in fluid need not be completely removed, thus the filter capacity of filter core 109, example
As the ion-exchange capacity of ion exchange resin, consumption are less.Therefore, the service life of filter core 109 can effectively be extended.This
Outside, when being used for drainage using the fluid purification 100 of ion exchange resin filter core, such as during tap water, it being capable of root
Need partly to cross the calcium and magnesium ion in drainage according to practical application, so as to form incrustation scale after avoiding the water heating after being processed.
