4 assume responsibility for the function of post active carbon filter core in conventional reverse osmosis water purifier, furthermore it is possible to by adjusting postposition clean unit
4 axial dimension come optimize path of the pure water by postposition clean unit 4 when and contact duration, with reach preferably purification imitate
Fruit.The first flow distribution plate 44 is placed on the bottom wall of cylinder 41, the first flow distribution plate 44 is equipped with multiple water holes 441, preferably, more
A water hole 441 is uniformly distributed on the first flow distribution plate 44, meanwhile, between the first flow distribution plate 44 and the bottom wall 412 of cylinder 41
The first shunting gap 442 is formed, the second through-hole 415 passes sequentially through and crosses water on the first shunting gap 442 and the first flow distribution plate 44
Hole 441 and communicated with granular activated carbon so that pure water after by the second through-hole 415 can effectively along first shunting gap
442 Radial Flows are disperseed, and are then uniformly entered from water hole 441 from the end of granular activated carbon, are avoided of subregion
Grain activated carbon is not used, and improves the utilization rate of granular activated carbon.Wherein, the inside setting of the bottom wall 412 of cylinder 41 is convex
The rib 436 risen, rib 436 and the first flow distribution plate 44 against so that form first and shunt gap 442, also, rib 436 along
It radially extends, is conducive to guide the dispersion of flow Radial Flow.In addition, the outer of the first flow distribution plate 44 can be with the inner wall of cylinder 41
Fitting positioning, can also pass through there are certain interval convenient for flow.Granular activated carbon is from water hole or other in order to prevent
Gap is revealed, and non-woven fabrics or nylon wire etc. can also be arranged in corresponding position can cross the structure of water.It is appreciated that between the first shunting
Gap can also be formed in alternative ways, such as：Rib or protrusion are set towards cylinder body bottom side in the first flow distribution plate, into
And support the first shunting gap；Exist alternatively, raised or step structure, the outer frame of the first flow distribution plate are arranged on cylinder inboard wall
In the protrusion or step structure, and then support the first shunting gap.Likewise, in order to avoid granular activated carbon is close to installation
The utilization rate at first end is uneven, and the second flow distribution plate can also be placed on the roof of cylinder, and the second flow distribution plate is equipped with multiple
Water hole, forms the second shunting gap between the second flow distribution plate and the bottom wall of cylinder, granular activated carbon passes sequentially through the second shunting
Water hole and second on plate shunt gap and are communicated with first through hole.
Isolation cover body 5 is equipped with the pure water through-hole 54 communicated with pure water outlet 12, pure water through-hole 54 close to 1 one end of mounting head
Periphery be equipped with water-carrying groove 55, water-carrying groove 55 is connected to first flow 51 and raw water inlet 11.Specifically, isolation cover body 5 is close
The outer end of 1 one end of mounting head pure water outlet pipe 56 with outward extension, pure water outlet pipe 56 constitutes pure water outlet 12, pure
Water through-hole 54 is located in pure water outlet pipe 56, and water-carrying groove 55 is located at the periphery of pure water outlet pipe 56, and the outer of water-carrying groove 55 passes through
Dowel 551 is connected and fixed with pure water outlet pipe 56, so that pure water outlet pipe 56 and isolation cover body 5 form integral piece, just
In whole reliable assembling, certainly, pure water outlet pipe and isolation cover body can also be seperated part, pure water outlet pipe by be isolated
Being realized against cooperation for the components such as cover body, cylinder is fixedly mounted.The roof 411 of cylinder 41 is equipped with and is communicated with pure water outlet 12
First through hole 414, the hole of first through hole 414 is along being equipped with the sealed wall 417 extended to 1 direction of mounting head, the insertion of sealed wall 417
In pure water outlet pipe 56 and form sealing cooperation.
In the present embodiment, it is equipped with waterway converter 6 between mounting head 1 and isolation cover body 5, waterway converter 6 is set in pure
Water outlet pipe 56 is outer and second flow channel 62 is formed between the tube wall of pure water outlet pipe 56, second flow channel 62 by water-carrying groove 55 with
First flow 51 communicates, and the periphery of water-carrying groove 55 has the sealing ring muscle 552 extended towards mounting head 1, waterway converter 6 separate
One end of mounting head 1 coordinates with the sealing of sealing ring muscle 552.Certainly, waterway converter can also be with isolation cover body by integral forming.Compared with
Excellent, it is to axially extend that the inner wall of waterway converter 6, which has the 6th guiding rib 64, the 6th guiding rib 64, is discharged with pure water
The assembly of pipe 56 plays guiding role during stretching into, also, to flow by having certain guiding role, on the other hand, the 6th
The outer wall of guiding rib 64 and pure water outlet pipe 56 is against positioning, in general, the 6th guiding rib 64 is at least three articles.Mounting head 1
With shell 2 generally by revolving molten connection, it is contemplated that rotation when rotation is molten between 6th guiding rib 64 and the outer wall of pure water outlet pipe 56
Turn, preferably, the gap of 0.2-1 millimeters of the two can be kept, and then avoids the two installation deviation.Both when in order to avoid revolving molten
It is damaged, following proposal can also be used, anti-pyrosphere mounting groove 561, anti-pyrosphere peace are set on the outer wall of pure water outlet pipe 56
The anti-pyrosphere of setting in tankage 561, be equipped in waterway converter 6 with anti-pyrosphere against anti-molten ring muscle 65, waterway converter 6 assembles
Afterwards, it is positioned by anti-pyrosphere and anti-molten ring muscle 65, since the two is continuous contact, greatly reduces the two during rotation is molten
The heat that generates of relative motion and probability to parts damages.Meanwhile the anti-ring muscle 65 that melts is fixed on by the 6th guiding rib 64
It is second to have gap 66, gap 66 in waterway converter 6, also, between anti-molten ring muscle 65 and the inner wall of waterway converter 6
The part in road 62, so that raw water passes through.
Between the outer wall and the inner wall of mounting head 1 of waterway converter 6 there is third to cross water space 23, third crosses water space 23
Water space 22 is crossed with second to communicate, and water space 22 and concentrated water water outlet 13 are crossed with connection second.Alternatively, can also be converted in water route
Third flow channel is set in device, and third flow channel and second cross water space and communicate, and the inner wall of the outer wall of waterway converter and mounting head
Sealing cooperation.
Element kit based on above structure, during water processed, raw water enters element kit, edge from raw water inlet 11
The second flow channel 62 between waterway converter 6 and pure water outlet pipe 56 flows, and isolation 5 He of cover body is entered by water-carrying groove 55
First flow 51 between cylinder 41 reaches reverse osmosis filter core 3 close to the end of mounting head 1 along first flow 51.It is then former
Water enters in raw water water guide layer, and axially passes through, and under the action of pressure before film, has part water to enter by reverse osmosis membrane 32
Pure water water guide layer forms pure water, and pure water is along pure water water guide laminar flow and progresses into central tube 31, then along central tube 31
It flows through the second through-hole 415 and enters the first shunting gap 442 in postposition clean unit 4, in the effect of the first flow distribution plate 44
Under, it is uniformly contacted with the filter material 42 in cylinder 41, after filter material 42, passes sequentially through first through hole 414, pure water water outlet
Pipe 56 is finally flowed out from pure water outlet 12.Part is not by the raw water of reverse osmosis membrane 32 from raw water water guide layer far from mounting head 1
One end flows out and forms concentrated water, and concentrated water passes sequentially through first, and water space 21, second crosses water space 22 excessively and third crosses water space 23,
Finally flowed out from concentrated water water outlet 13.
