Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
The flow passage structure of the composite filter element component 1000 of the utility model embodiment is described below with reference to Fig. 1-Figure 12.
According to a kind of flow passage structure of composite filter element component 1000 of the utility model embodiment, as shown in Figure 2, comprising:
The first filter element 100 and the second filter element 200 of axially spaced setting.
First filter element 100 has first import and export 101, second import and export 102 and third inlet and outlet 201, the second mistake
Filtering unit 200 has the 4th inlet and outlet 302, and transition runner is equipped between the first filter element 100 and the second filter element 200
24.The first filter element 100 and the second filter element 200 herein connects in axially spaced setting, and by transition runner 24
It connects, the first filter element 100 and the second filter element 200 cooperate compact, formation entirety, and save the connecting tube of portion of external
Road.
Wherein, the first uniformly distributed runner 11, first is radially disposed in the first filter element 100 from outside to inside to filter
Channel 13, second is evenly distributed with runner 12, third is evenly distributed with runner 21, the second filtration channel 23 and the 4th is evenly distributed with runner 22.
It is equipped with the first filtration members 10 in first filtration channel 13, is equipped with the second filtration members 20 in the second filtration channel 23.This
Place, 20 two purification water routes of the first filtration members 10 and the second filtration members can increase the strainability of the first filter element 100, full
The different water quality outlet effect requirement of foot.
First uniformly distributed runner 11 is connected to the second uniformly distributed runner 12 by the first filtration channel 13, third be evenly distributed with runner 21 and
4th uniformly distributed runner 22 is connected to by the second filtration channel 23.Herein, one in the uniformly distributed runner on 13 both sides of the first filtration channel
A liquid being evenly distributed with before the filtering of the first filtration members 10, another can then be evenly distributed with the filtered liquid of the first filtration members 10, and first
10 both sides of filtration members are pressurized uniform.Similarly, one in the uniformly distributed runner on 23 both sides of the second filtration channel can be evenly distributed with the second mistake
The liquid before part 20 filters is filtered, another can be evenly distributed with the filtered liquid of the second filtration members 20, and 20 both sides of the second filtration members are pressurized
Uniformly.
Second uniformly distributed runner 12 and third are evenly distributed with to completely cut off between runner 21 and not circulate.Completely cut off the uniformly distributed stream of two not circulated
Road, makes two mutually independent purification water routes in the first filter element 100, and when work does not interfere with each other.One of purification water route
Water outlet can directly as another purification water route water inlet；The water outlet in one of purification water route, can also lead to it is external its
After his filter assemblies filtering, it is re-used as the water inlet in another purification water route.
First uniformly distributed runner 11 connects first import and export 101, and the second uniformly distributed runner 12 connects second import and export 102.Herein,
If liquid-inlet of the first import and export 101 as the first filtration members 10, as the first filtration members 10 if second import and export 102
Liquid outlet；If liquid outlet of the first import and export 101 as the first filtration members 10, first is used as if second import and export 102
The liquid-inlet of filtration members 10.
Third is evenly distributed with the connection third inlet and outlet 201 in runner 21 and the 4th uniformly distributed runner 22, and third is evenly distributed with runner
21 and the 4th another connection transition runner 24 in uniformly distributed runner 22.Herein, transition runner is connected when third is evenly distributed with runner 21
When 24, the 4th uniformly distributed runner 22 then connects third inlet and outlet 201；When third, which is evenly distributed with runner 21, connects third inlet and outlet 201, the
Four uniformly distributed runners 22 then connect transition runner 24.
Third filtration members 30 are equipped in second filter element 200.Herein, third filtration members 30 can further increase composite filter
The whole filtering function of core assembly 1000, promotes the quality of water outlet.
It is understood that being radially successively arranged four in the first filter element 100, uniformly runners and two filterings are logical
Road is respectively disposed with filtration members in two filtration channels to form two mutually independent purification water routes.So that the first filtering is single
Compact overall structure in member 100, and to be integrated with twice water filtration link in the first filter element 100, along with the
One group of filtration members in two filter elements 200, so that the composite filter element component 1000 of the utility model is whole to have three water quality
Filter link.
First filter element 100 and the second filter element 200 in axially spaced setting, 20 two sides of the second filtration members its
In a uniformly distributed runner third filtration members 30 are connected by transition runner 24, two filter elements (100,200) cooperation is compact, saves
The external connection pipeline of the filtered water of third filtration members 30 required laying when flowing to the filtering of second filtration members 20；Or section
The external connection pipeline of the filtered water of the second filtration members 20 required laying when flowing to third filtration members 30 and filtering is saved.Have
Reduce overall dimensions conducive to composite filter element component 1000, is conducive to the arrangement for simplifying exterior line.
From the first uniformly distributed runner 11, the first filtration channel 13, second is evenly distributed with runner 12, third is evenly distributed with runner 21, the second mistake
From the point of view of the placement position for filtering channel 23 and the 4th uniformly distributed runner 22, water flow is passing through the first filtration members 10 and the second filtration members 20
When, it is most of along the first filter element 100 radially across passing through that path is short, circulation is big.And radially across when to filtering
The impurity on part surface has souring, and water flow is easier to pass through filtration members after washing impurity open.And each filtration members are in Inlet and outlet water
Most of water flow is substantially axial flow, and it is uniformly distributed to not only contribute to water flow in this way, is also beneficial to take to the impurity under washing away the
Axial one end of one filter element 100, avoids impurity from getting lodged in filtration members surface.
First filter element 100 and the second filter element 200 are arranged in the same composite filter element component 1000, one
Change degree is high, is conducive to reduce structure size, only needs a set of positioning, mounting structure when composite filter element component 1000 is installed,
