Road；End cap 3 is installed in the bottom of the filter core inner bag and element kit is formed, in the present embodiment, end cap 3 is hollow, inwall tool
There is step, reverse osmosis membrane is seated on the step, the end of central tube 21 is stretched into end cap 3.
Above-mentioned filter housing 1 is designed to cylinder-shaped structure, and the bottom of filter housing 1 is provided with raw water inlet 11, can be with water purification passage
The water purification delivery port 12 being connected and be connected with concentrated water passage concentrated water outlet 13, the raw water inlet, pure water inlet and
Concentrated water outlet in be separately installed with water check valve 4, while in filter housing bottom interior wall have for above-mentioned element kit plug it is spacing
Circle, is provided with sealing ring 5 between the spacing collar and element kit.In the present embodiment, spacing collar has two, i.e., inside and outside distribution
First spacing collar 14 and the second spacing collar 15, wherein the first limit circle 14 is connected with the end phase inserting of central tube 21, second is spacing
Circle 15 is connected with the phase inserting of head 31 on end cap 3, and two such spacing collar is while support central tube 21 and reverse osmosis membrane 22, make
Positioning of the filter core inner bag 2 in filter housing 1 is obtained more to stablize.Now, corresponding sealing ring 5 also has two, i.e., sealing ring is by setting
Put the first sealing ring 5a between above-mentioned first spacing collar and central tube and be arranged on the second spacing collar and end cap head it
Between the second sealing ring 5b composition, the first sealing ring 5a has two, in the seal groove for being respectively positioned on the end of central tube 21.Second sealing
Enclose 5b to be then located in the seal groove on the head on end cap 3, so that inserting junction has preferable sealing property.
Above-mentioned water check valve 4 can use the valve arrangement of prior art, but even more preferably use check valve form, and it includes
Have and filter housing 1 mutually fixed gland 41 with through hole and the water stop valve core 42 being engaged with the port of through hole, wherein gland 41
The corresponding water-in and water-out that filter housing 1 can be positioned at by ultrasonic wave or glue are intraoral, and water stop valve core 42 offsets with the one end of spring 43,
The other end of spring 43 offsets to the inwall of above-mentioned corresponding water inlet or delivery port, so that water stop valve core has clogging lead to all the time
The trend of nose end mouthful, and in order to improve sealing during closing, the 3rd sealing is additionally provided between water stop valve core and through hole port
Circle 6.
In order to further improve stability of the filter core inner bag 2 after filter housing 1, the upper end of filter core inner bag 2 is also arranged with
Inner cap 7, the neighboring of the inner cap has the bending edge 71 being engaged with the inwall of filter housing 1.Simultaneously in order that this modular filter core knot
Each entery and delivery port of structure and the correct grafting of connector on integrating water route plate, have the positioning of axially distribution on the outer wall of filter housing 1
Muscle 16.
During assembling, first the entery and delivery port in the bottom of filter housing 1 is provided with spring 43, the sealing ring 6 of water stop valve core 42 and the 3rd,
And gland 41 is fixed with ultrasonic wave or glue, then the end cap 3 for being provided with the second sealing ring 5b is enclosed under filter core inner bag
End, and be fastened by special adhesive tape, then above-mentioned element kit is placed in filter housing 1, made with the first sealing ring 5a
The end of central tube 21 is plugged in the first spacing collar 14, and the head 31 on end cap 3 is plugged in the second spacing collar 15.Then in filter
The upper end of in-core courage 2 covers inward upper cover 7, the bending edge 71 of inner cap is kept out in the inwall of filter housing 1, to prevent filter core inner bag 2 in filter housing
Rock；The last mouth thread connection upper filter lid 8 in filter housing, to cover the oral area of filter housing.
In use, after being connected with integrating water route plate, each filter core connector opens water stop valve core top, and raw water is intake by raw water
Mouth is entered in filter core inner bag, and the water purification in filter core inner bag in water purification passage is flowed out by water purification delivery port, meanwhile, in filter core
Concentrated water in courage in concentrated water passage is flowed out by concentrated water delivery port, shown in Figure 4.
When the filter core inner bag in above-described embodiment is the structure of non-reverse osmosis membrane, i.e., using existing other material for core
When, in the above-described embodiments, the bottom of filter housing 1 can be in order to avoid open concentrated water delivery port, and now end cap can be designed to following structure, such as schemes
There is hub-interface 32 and support filter core that the support tube 21 ' for filter core inner bag 2 ' is planted shown in 5, on the upper surface of end cap 3 '
Annular groove 33, the lower surface of end cap has the connection-peg 34 being plugged on spacing collar, i.e. filter core inner bag 2 ' is completely supported at end cap
On 3 ', the connection-peg 34 only on end cap 3 ' is plugged in spacing collar, and this structure, spacing collar quantity is few, and plugging position accordingly subtracts
It is few, the quantity of sealing ring is also just reduced, therefore it is less susceptible to make the growth of bacterium, use relatively sanitary.
