107 are arranged on the outer end face of filter cover 101, more convenient when so the composite filter element is external.
Filter cover 101 is detachably connected with the non-dismountable connection of lauter tub 102 or filter cover 101 with lauter tub 102.Removably set
The mode of setting can facilitate the replacement of 100 internal filter component of shell.
It is also specifically disclosed that in the utility model embodiment, the concrete structure of filter cover 101, on the inner face of the filter cover 101
It is provided with：The first mounting portion 1011 for installing level V filter layer 200；
The second mounting portion 1012 for installing isolated part 400；
Third mounting portion 1013 for installing level Four filter assemblies 300；With
The 4th mounting portion 1014 for installing lauter tub 102；
The area of original water inlet 103 and ultrafiltration water out 104 between the 4th mounting portion 1014 and third mounting portion 1013
Domain；Due to, level Four filter assemblies 300 are sequentially arranged from outside to inside with level V filter layer 200, shell 100 radially, four
Grade filter assemblies 300 are located at the periphery of entire Pyatyi filter layer, original water inlet 103 corresponding with level Four filter assemblies 300 and surpass
Filtered water outlet 104 is arranged on 101 position of filter cover corresponding with level Four filter assemblies 300, and therefore, adopting the structure can be with
Maximum optimization filtration path, meanwhile, facilitate external pipeline.
Concentration water out 107 is located at the region between third mounting portion 1013 and the second mounting portion 1012.
Ultrafiltration water enters area of the water inlet 105 of RO films between the second mounting portion 1012 and the first mounting portion 1011
Domain；Similarly, since level Four filter assemblies 300 and level V filter layer 200 are sequentially arranged from outside to inside, with level V filter layer
The water inlet 105 that 200 corresponding ultrafiltration water enter RO films is arranged in filter cover corresponding with level V filter layer 200 101
Position can advanced optimize filtration path.Region of the pure water outlet 106 between the first mounting portion 1011.
Above-mentioned filter cover 101 in the utility model embodiment is level Four filter assemblies 300, isolated part 400 and level V
Filter layer 200 provides installation and supports, wherein being provided with corresponding helicitic texture on each mounting portion to realize between each structure
Be fastenedly connected.
And the arrangement of each intake-outlet, optimization filtration path arrange each intake-outlet using the above form for convenience.
In further embodiment, level Four filter assemblies 300, third mounting portion 1013, the 4th mounting portion 1014 and lauter tub
Raw water channel A, level Four ultrafiltration aquaporin B are formed between 102, wherein raw water channel A is connected to original water inlet 103, level Four ultrafiltration
Aquaporin B is connected to ultrafiltration water out 104；
Level V filter layer 200, the first mounting portion 1011, the second mounting portion 1012 and isolated part 400 form ultrafiltration water
Into RO membrane channels D, RO pure water channel E and concentration aquaporin F, wherein ultrafiltration water enters RO membrane channels D and enters with ultrafiltration water
The water inlet 105 of RO films is connected to；RO pure water channel E is connected to pure water outlet 106；Concentrate aquaporin F and concentration water out 107
Connection.
Since RO films are axial arranged or radial arrangement, so-called axial arranged finger water to be filtered passes axially through RO films, and
It is filtered axially, so-called radial arrangement refers to water to be filtered in radial direction through RO films, and is filtered radially.This practicality is new
In type embodiment, it is preferable that RO films are axial arranged, and the middle part of RO films is Pyatyi drainage channel.
When using the composite filter element, raw water is entered to by original water inlet 103 inside shell 100, flows into raw water channel warp
It crosses and carries out three-stage filtration under the filtration of three-stage filtration component 302, fourth stage filter layer 301 is passed through in filtered three-level water purification
Level Four filtering is carried out, filtered level Four ultrafiltration water flows into level Four drainage channel B and flowed out by ultrafiltration water out 104, should
Level Four ultrafiltration water is capable of direct drinking, or accesses the water inlet 105 that ultrafiltration water enters RO films by external supercharging equipment.
The filtered ultrafiltration water of level Four enters RO films by water inlet 105, and RO UF membranes go out pure water and condensed water, and RO is pure
Water is flowed out from pure water mouth 106, and condensed water is capable of direct drinking from the concentration outflow pure water of water out 107.Since the utility model is implemented
In example, three-stage filtration component 302 respectively include the first PE layer, active carbon layer, the 2nd PE layers, fourth stage filter layer 301 is ultrafiltration
Film, therefore, the filtered water of level Four after level Four filter assemblies 300 are ultrafiltration water.And level V filter layer 200 is RO
Film, therefore, Pyatyi drainage are RO pure water.
In order to prevent when replacing entire filter core, the water outflow inside shell 100, ultrafiltration water enters RO films water inlet 105
