The specific embodiment
Fig. 1 shows according to the sectional structure chart of the fluid purification 100 of an embodiment of the utility model.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:
Particularly, housing 101 comprises lid 113 and cavity 115, and this lid 113 is threaded connection 117 with cavity 115 and mutually couples, and to form substantially airtight sealed chamber, 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, export the 105, 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 are 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.

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, from exporting impurity to be filtered (such as calcium, magnesium ion) concentration the fluid of 105 outflows, be less than the impurity concentration to be filtered in the fluid of import 103, but be greater than the impurity concentration to be filtered the fluid flowing out from filter core 109, therefore, in general, the concentration of 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, impurity substances concentration in fluid after being processed by fluid purification 100 significantly depends in the unit interval ratio with 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, 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 with the mobile rate of flow of fluid of 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 that the aperture of this fluid bypass passageway 111 is configured to the impurity of this part fluid flowing out from this fluid bypass passageway 111 and the mixed fluid of part fluid flowing out from filter chamber 107 is not 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, thus 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, for example the ion-exchange capacity of ion exchange resin, consumes less.Therefore, can effectively be extended the service life of filter core 109.In addition, when adopting the fluid purification 100 of ion exchange resin filter core to be used to filtered water, for example, during 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 according to the generalized section of the fluid purification 200 of another embodiment of the utility model.
