A water outlet end cap 30 may be provided at one end (e.g., an upper end as shown in fig. 1) of the support pipe 10, and the water outlet end cap 30 may be provided to cover one end of the filter element 20, and a concentrated water outlet 31 may be provided to the water outlet end cap 30, the concentrated water being the water remaining after the raw water is filtered, and the concentrated water may be discharged from the water filter assembly 100 through the concentrated water outlet 31.
A water inlet end cap 40 may be provided at the other end (e.g., the lower end as shown in fig. 1) of the support tube 10, and the water inlet end cap 40 may be provided to cover the other end of the filter element 20. A plurality of arc-shaped diversion trenches 42 can be arranged on the upstream surface of the water inlet end cover 40, the arc-shaped diversion trenches 42 can be distributed along the circumferential direction of the water inlet end cover 40, and the arc-shaped diversion trenches 42 extend towards the center of the water inlet end cover 40. The bottom wall surface of the arc-shaped diversion trench 42 is provided with a water inlet 41, and the water inlet 41 can be arranged at the outer end of the bottom wall surface of the arc-shaped diversion trench 42, for example, as shown in fig. 2 and 3; the water inlet 41 may be provided at an inner end of a bottom wall surface of the arc-shaped diversion trench 42 as shown in fig. 14 and 15, for example. The water inlet 41 may communicate with the filter element 20 such that raw water may flow to the filter element 20 through the water inlet 41, filtered by the filter element 20, and then flows into the water outlet passage 11 from the water passing hole 21. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
Here, the upstream surface of the water inlet cover 40 is a surface of the water inlet cover 40 for receiving water flow, that is, a surface facing substantially the direction of water flow, for example, in the specific example shown in fig. 1, the water inlet cover 40 is provided at the lower portion of the support pipe 10, the upstream surface of the water inlet cover 40 is a lower end surface of the water inlet cover 40, and the bottom wall surface of the arc-shaped diversion trench 42 is a lower wall surface of the arc-shaped diversion trench 42. When the water inlet end cover 40 is arranged on the upper part of the support pipe 10, the upstream surface of the water inlet end cover 40 is the upper end surface of the water inlet end cover 40, and the bottom wall surface of the arc-shaped diversion trench 42 is the upper wall surface of the arc-shaped diversion trench 42.
The raw water passing through the arc-shaped diversion trench 42 may form a rotational vortex and an internal turbulent flow thereof. The rotary vortex flow enters the filter element 20 through the water inlet 41, the filtered pure water flows into the water outlet channel 11 through the water passing holes 21 on the support tube 10 after being filtered by the filter element 20, the pure water flows out through the pure water outlet 12 at the opening of the water outlet channel 11, and the concentrated water flows out through the concentrated water outlet 31 on the water outlet end cover 30, so that the filtration of raw water is completed.
In the related art, the water flow in the water filtering member directly passes through the filter element in a straight direction, but in the embodiment of the present invention, the water flow may form a rotating vortex in the water filtering assembly 100, and the filtering effect is better because the filtering path through which the rotating vortex passes is longer than the filtering path through which the water flow directly passes through the filter element 20. In the related art, both ends of the water filtering member have no end caps, and the flow areas of the water inlet end and the water outlet end are the same, but in the embodiment of the present invention, by adding end caps at both ends of the filter element 20 and adjusting the size of the water inlet and outlet holes on the end caps, the pressure difference and the flow difference inside the water filtering assembly 100 can be adjusted, so that the inside of the filter element 20 is pressurized or maintained, thereby improving the filtering performance.
According to the water filtering assembly 100 of the embodiment of the invention, by arranging the water inlet end cover 40 and the water outlet end cover 30, arranging a plurality of arc-shaped diversion trenches 42 on the upstream surface of the water inlet end cover 40, arranging the water inlet 41 communicated with the filter element 20 at the inner end or the outer end of the bottom wall surface of the arc-shaped diversion trenches 42, and after raw water flows in from the water inlet 41 on the water inlet end cover 40, the water flows along the plurality of arc-shaped diversion trenches 42 on the upstream surface of the water inlet end cover 40 to form a plurality of vortex flows rotating along the filtering direction of the filter element 20, so that the filtering flow passage of the water flowing through the filter element 20 is prolonged, and the filtering performance of the water filtering assembly 100 is better and the filtering efficiency is improved. And the pressure difference and the flow difference at both ends of the filter element 20 can be adjusted by adjusting the sizes of the water inlet 41 and the concentrated water outlet 31, so that the inside of the filter element 20 is pressurized or maintained, and the filtering performance of the water filtering assembly 100 is improved.
As shown in fig. 2 and 3, an open groove may be provided on the upstream surface of the water inlet cap 40 according to one embodiment of the present invention. The open channel may have a plurality of arcuate guide walls 43 therein, the arcuate guide walls 43 extending generally toward the center of the water inlet end cap 40. The plurality of arc-shaped guide walls 43 can divide the open slot into a plurality of arc-shaped guide slots 42. When the raw water passes through the plurality of arc-shaped diversion trenches 42, a plurality of vortexes rotating in the direction of the arc-shaped diversion walls 43 are formed, and the vortexes enter the filter element 20 through the water inlet 41.
Alternatively, as shown in fig. 2 and 3, a plurality of drainage grooves 44 may be provided on the bottom wall surface of the arc-shaped diversion trench 42. The drainage groove 44 may extend substantially along the circumferential direction of the water inlet cover 40, one end of the drainage groove 44 may be connected to the water inlet 41, and the other end of the drainage groove 44 may be connected to the arc-shaped guide wall 43. Raw water enters the filter element 20 through the water inlet 41 by being guided by the guide groove 44 after passing through the arc-shaped guide groove 42 formed by the arc-shaped guide wall 43. Therefore, the water flow is guided by the guiding groove 44, the formation of the rotary vortex is facilitated, and the guiding groove 44 has better guiding property on raw water.
With continued reference to fig. 2 and 3, in accordance with some embodiments of the present invention, the bottom wall surface of the arcuate channel 42 may be formed as an arcuate surface extending obliquely to the side of the filter element 20 and to the side of the water inlet 41. Specifically, when the water inlet end cover 40 is located at the lower end of the filter element 20, the bottom wall surface of the arc-shaped diversion trench 42 is the lower wall surface of the water inlet end cover 40, and the side of the lower wall surface facing the water inlet 41 is inclined to the upper side of the filter element 20 along the radial direction of the water inlet end cover 40 to form an arc-shaped surface; when the water inlet end cover 40 is located at the upper end of the filter element 20, the bottom wall surface of the arc-shaped diversion trench 42 is the upper wall surface of the water inlet end cover 40, and the side of the upper wall surface facing the water inlet 41 is inclined to the lower side of the filter element 20 along the radial direction of the water inlet end cover, so as to form an arc-shaped surface.
For example, in the embodiment shown in fig. 6, the water inlet 41 is located at the outer side of the water inlet end cap 40, the water inlet end cap 40 is located at the lower end of the filter element 20, the bottom wall surface of the arc-shaped diversion trench 42 is the lower wall surface of the water inlet end cap 40, and the lower wall surface extends upwards towards the outer side direction of the water inlet end cap 40 to form an arc-shaped surface. Or for example, in the embodiment shown in fig. 18, the water inlet 41 is located inside the water inlet end cover 40, the water inlet end cover 40 is at the lower end of the filter element 20, the bottom wall surface of the arc-shaped diversion trench 42 is the lower wall surface of the water inlet end cover 40, and the lower wall surface extends upwards towards the inside direction of the water inlet end cover 40 to form an arc surface. Thus, when the raw water passes through the arc-shaped diversion trench 42 having the arc-shaped bottom wall surface, the swirling vortex flow is easily formed and the raw water is facilitated to flow in the direction of the filter element 20.
In some embodiments of the present invention, the concentrated water outlet 31 and the water inlet 41 may be disposed apart from each other in a radial direction of the water filter assembly 20. For example, as shown in fig. 1 to 12, the water inlet 41 may be disposed at a position near the outside of the water inlet end cap 40, and the concentrated water outlet 31 may be disposed at a position near the inside of the water outlet end cap 30; as shown in fig. 13-22, the water inlet 41 may be disposed near the inside of the water inlet cap 40 and the concentrate water outlet 31 may be disposed near the outside of the water outlet cap 30. The flow of water from the water inlet 41 to the concentrate outlet 31 is in the form of a longer filter passage. Thereby, the filtering performance of the filter assembly 100 is improved.
As shown in fig. 1, 7, 13 and 19, the middle portion of the water outlet end cap 30 may optionally be provided with a mounting outlet 32 that is axially through and for passing the support tube 10. In other words, the middle of the water outlet end cap 30 may be provided with a mounting outlet 32, the mounting outlet 32 extending axially through the water outlet end cap 30, the mounting outlet 32 being adapted to pass through the support tube 10. Thus, the water outlet end cap 30 and the support tube 10 are fixed with good effect and are convenient to install.
In the embodiment shown in fig. 7, further, the concentrated water outlet 31 may include a plurality of concentrated water outlets 31 may be provided at a position near the inside of the water outlet end cap 30, the plurality of concentrated water outlets 31 may be distributed along the circumferential direction of the mounting outlet 32, and the plurality of concentrated water outlets 31 may be distributed on the inner circumferential wall surface of the mounting outlet 32. For example, as shown in fig. 7 to 12, a plurality of projections 33 may be provided on the inner peripheral wall surface of the mounting outlet 32, and concentrated water outlets 31 may be formed between two adjacent projections 33, and the concentrated water may flow out from the concentrated water outlets 31 between the projections 33.
It should be noted that the manner in which the projections 33 are provided to form the concentrated water outlet 31 is merely an example, and is not to be construed as limiting the present invention. For example, a plurality of notches may be provided in the inner peripheral wall surface of the water outlet cap 30 near the mounting outlet 32, each of the notches being formed as a concentrated water outlet 31, and the concentrated water may flow out from the concentrated water outlet 31 formed by the notch. Thus, the provision of the plurality of concentrated water outlets 31 makes the efficiency of the concentrated water discharge high.
