Detailed description of the invention
Fig. 1 shows the sectional structure chart of fluid purification 100 according to an embodiment of the invention.This fluid purification 100 is suitable for being applied in household water filter, or is applied in other and is used for equipment or the application scenario of the impurity substances in filtered water or other liquid.In the embodiment shown in fig. 1, this fluid purification 100 is integrated in water purifier, and this water purifier can be for filtering former water, running water, the aqueous solution or other fluids.
As shown in Figure 1, this fluid purification 100 comprises:
Housing 101, it has import 103 and outlet 105;
Filter chamber 107, it is arranged in housing 101, and for holding filter core 109, wherein this filter chamber 107 is fluidly communicated with import 103 and outlet 105; And
Fluid bypass passageway 111, it is arranged in housing 101, and is fluidly communicated with import 103 and outlet 105, with allow at least a portion by import 103 flow into fluid in housing 101 via fluid bypass passageway 111 from exporting 105 outflows.
Particularly, housing 101 comprises lid 113 and cavity 115, and this lid 113 is threaded connection 117 with cavity 115 and mutually couples, to form substantially airtight sealed chamber, i.e. and filter chamber 107.117 places that are threaded are also provided with sealing ring 119, and it is for improving further the sealing property between lid 113 and cavity 115, to avoid fluid to flow out from its gap location.
On lid 113, also comprise hybrid chamber 118, (this hybrid chamber 118 has two import 118a, 118b at upstream extremity, correspond respectively to the outlet of fluid bypass passageway 111 and the outlet of filter chamber 107), receive respectively from the unfiltered fluid of fluid bypass passageway 111 with from the fluid being filtered of filter chamber 107, this hybrid chamber 118 has outlet 118c to allow mixed fluid to flow out in downstream.
In this embodiment, filter chamber 107 is tubular.Correspondingly, the filter core 109 holding in filter chamber 107 is also the sleeve-shaped adapting with filter chamber 107 shapes.In other example, filter core 109 also can be filter membrane, filter screen shape or other applicable shapes.One end in contact cavity 115 bottoms of this filter core 109, the other end of filter core 109 contacts the bottom of lid 113, thereby makes filter core 109 be held and be fixed in filter chamber 107.On lid 113, be provided with import 103, outlet 105, the first middle perforate 121 and the second middle perforate 123; Wherein, this first middle perforate 121 is fluidly communicated with import 103, and the second middle opening 123 is fluidly communicated with outlet 105, thereby make the filter chamber 107 jointly being limited by lid 113 and cavity 115 fluidly be communicated to import 103 via the first middle perforate 121, and be fluidly communicated to outlet 105 via the second middle perforate 123.
In one embodiment, filter core 109 is ion exchange resin filter cores, and it has ion-exchange capacity, is suitable for calcium in filtered water, magnesium ion or other and is easy to form the ion of incrustation scale.At some, in other example, the filter element that filter core 109 also can be filtered with physics or chemical mode by other substitutes, and further, this filter element can be housed in filter cylinder.
In the embodiment shown in fig. 1, fluid bypass passageway 111 is arranged in lid 113, and it is communicated with import 103 and outlet 105 by the through hole in lid 113 or pipeline.At some, in other example, fluid bypass passageway 111 also can be arranged on other positions of housing 101, for example, be arranged in filter chamber 107.For example, the length of filter core 109 can be slightly less than the spacing of lid 113 bottoms and cavity 115 bottoms, or the subregion of filter core 109 certain one end does not contact completely with lid 113 bottoms or cavity 115 bottoms, thereby make to leave the effectively breach of impurity screening in filter chamber 107, this breach has formed the fluid bypass passageway 111 that makes fluid section bypass.
Can find out, for flowing into the fluid in housing 101 by import 103, its part can flow through housing 101 with the first fluid flow path 11 via by filter chamber 107, and flows out from exporting 105; Another part can flow through housing 101 via the second fluid flow path 12 by fluid bypass passageway 111, and flows out from exporting 105.
Particularly, for the mobile fluid of first fluid flow path 11, it can be filtered by filter core 109 and effectively remove impurity substances wherein, and therefore, this filter chamber 107 that is provided with filter core 109 also can be described as fluid filtering passage.In this embodiment, in the middle of the first middle perforate 121 and second, perforate 123 is arranged on the inside and outside of sleeve-shaped filter core 109 respectively.Like this, via the mobile fluid of first fluid flow path 11 filter core 109 of must flowing through, this is conducive to the filtration of filter core 109 convection cells.
On the other hand, owing to not being provided with filter core 109 or other similar filter elements in fluid bypass passageway 111, thereby for the mobile fluid of second fluid flow path 12, it can not be filtered, thereby impurity substances wherein, more must be by the mineral ion of filtering, for example calcium, magnesium ion, still can be retained in this fluid after processed.Like this, be less than the impurity concentration to be filtered in the fluid of import 103 from exporting impurity to be filtered (such as calcium, magnesium ion) concentration the fluid of 105 outflows, but be greater than the impurity concentration to be filtered the fluid flowing out from filter core 109, therefore, in general, concentration by the impurity to be filtered in the fluid of these fluid purification 100 purified treatment can be adjusted to particular value, to meet the needs of practical application.
Be appreciated that, significantly being depended in the unit interval ratio with the cumulative volume with first fluid flow path 11 and the mobile fluid of second fluid flow path 12 with the volume of the mobile fluid of second fluid flow path 12 by the impurity substances concentration in fluid purification 100 fluid after treatment, is also the bypass rate of fluid bypass passageway 111.In actual applications, can change the minimum-value aperture of fluid bypass passageway 111, or the length that changes this fluid bypass passageway 111 changes the rate of flow of fluid mobile with second fluid flow path 12 (or flow), thereby adjust the ratio of two parts fluid, and then change the impurity concentration of the fluid being flowed out by outlet 105.In fluid purification 100 as shown in Figure 1, the concentration of the impurity of this part fluid that the aperture of this fluid bypass passageway 111 is configured to flow out from this fluid bypass passageway 111 and the mixed fluid of part fluid that flows out from filter chamber 107 is similar to the similar deposit of incrustation scale so that it can not produce within preset range.To those skilled in the art, when he or she knows the structure of filter chamber and can not produce after the similar sedimental restrictive condition of incrustation scale, he or she just can easily obtain fluid bypass passageway 111 at the diameter range of the most carefully locating without excessive test.And water quality situation (hard or soft) the convection cell bypass channel 111 that those skilled in the art also can be regional according to each designs, therefore this fluid bypass passageway 111 because of regional difference can be different.
Can find out, because the impurity substances in fluid is without being completely removed, thereby the filter capacity of filter core 109, the ion-exchange capacity of for example ion exchange resin, consumes less.Therefore, can effectively be extended the service life of filter core 109.In addition, when the fluid purification 100 that adopts ion exchange resin filter core is used to filtered water, for example, when running water, it can need calcium, the magnesium ion in filtered water partly according to practical application, thereby avoids forming incrustation scale after the water heating after processed.
Fig. 2 shows the generalized section of fluid purification 200 according to another embodiment of the present invention.
As shown in Figure 2, this fluid purification 200 comprises:
Housing 201, it has import 203 and outlet 205;
Filter chamber 207 (restriction fluid filtering passage), it is arranged in housing 201, and for holding filter core 209, wherein this filter chamber 207 is fluidly communicated with import 203 and outlet 205;
