Description
Technical field
The present invention relates to purifier fields, and in particular to a kind of with three interface modules of end, fast-connection filter element and water purifier.
Background technique
Reverse osmosis filter core in household water-purifying machine will more renew filter core when service life ends in time, to guarantee machine
The water quality of water outlet meets hygienic requirements and effluent flux meets the requirements, in order to reduce operation difficulty when filter element replacing, in recent years
It is a large amount of to use dismounting very easily Quick connection-type filter element.Original water inlet, concentrated water outlet and the water purification outlet of this filter core are arranged at
The same end of filter core, water purifier are equipped with the filter cartridge seat with the mating mountable filter core of the filter core, and filter core is removed from filter cartridge seat
It means that and disconnects the water route on all intake-outlets of filter core and filter cartridge seat, filter core is loaded into filter cartridge seat and means that and will filter
All intake-outlets of core are connected to water route corresponding in filter cartridge seat, so, the dismounting of filter core is simultaneously with filter cartridge seat and filter core
Between pipeline off and on.Now, on the market with this function reverse osmosis fast-connection filter element (well-known technique it is reverse osmosis
Fast-connection filter element) all inlet and outlet occur more than the water flow passage interface position in the form of concentric circles, and the axis in its center of circle and filter
Wire mandrel is overlapped, and as depicted in figs. 1 and 2, inner circle 1 is water purification water outlet, and inner circle area is exactly the cross section in water purification channel 1001
Area, the middle annulus 2 outside inner circle 1 is concentrated water water outlet, and the area of middle annulus 2 is exactly the area in concentrated water channel 2001, middle circle
The outside of ring 2 is large circle 3, and the area of large circle 3 is exactly the area in raw water channel 3001.Such structure exists asks as follows
Topic:
1. filter core is bigger in the internal pressure thrust of filter core interface at runtime.
Due to raw water from the raw water water inlet end of rolled membrane module through the mistake of the raw water effluent of reverse osmosis membrane to concentrated water water outlet
Resistance to water-flow is smaller in journey, can approximatively think the water pressure of rolled membrane module raw water water inlet end and the hydraulic pressure of concentrated water water outlet
Power is equal, is P2.In addition, pure water outlet often connects pressure water storage barrel, pressure P1 is usually up to 0.3MPa in water butt.It is this
The internal pressure thrust of quick-connected filter element structure can be estimated as the following formula:
F indicates internal pressure thrust in formula, and unit N, d indicate that the overall diameter of large circle 3, unit mm, d0 indicate inner circle 1
Overall diameter, unit mm.By taking the reverse osmosis fast-connection filter element of domestic certain brand enterprise production as an example, the large circle outer diameter of the filter core
D is 38mm, and the overall diameter d0 of inner circle is 8mm, and the hydraulic pressure P2 at raw water inlet is 0.6MPa, and pressure P1 is at water purification outlet
When 0.3MPa, can be calculated internal pressure thrust F through above formula is 665N.This internal pressure thrust is very big.Internal pressure thrust is to promote
The power that filter core and filter cartridge seat are separated from each other.Internal pressure thrust is bigger, higher to the coupling reliability requirement between filter core and water purifier,
The leakproofness that water route in filter core couples with the water route of water purifier is influenced also bigger.So good design structure should be maximum
Reduce internal pressure thrust to limit.
2. being not easy to design plate of water route.
It is this all intake-outlets in water flow passage interface position be in concentric structure reverse osmosis fast-connection filter element, it is desirable that water purification
The position of any two opening (import or export) corresponding with filter core, cannot converge in filter core axis on machine filter core print seat
Same position requires the axis in any two water route of filter cartridge seat that cannot intersect in filter core axis same position in other words.This
Sample, when plate of water route plane is arranged to vertical with filter core axis, (this design can be substantially reduced water purifier size, to reduce
Cost), resulting in plate of water route plane and plane determined by the raw water water inlet water route and concentrated water water outlet water route in filter cartridge seat is not
In same plane, actual conditions are then often mutually perpendicular to, compared with this results in the coupling structure between plate of water route and filter cartridge seat
Complexity causes manufacture difficulty to increase, and manufacturing cost rises.
3. leading to water purification exhalant canal since filter core is in concentric structure in all inlet and outlet in water flow passage interface position
Minimum cross-sectional area diameter very little, by taking the reverse osmosis fast-connection filter element of domestic certain brand enterprise production as an example, which only has
3.5mm, than internal diameter (4.2mm) that in industry 2 are in charge of also than it is small.This is because caused by unreasonable structure, because if directly
The minimum cross-sectional area of water purification exhalant canal is increased, just will increase the diameter of the large circle, the diameter of large circle increases just
Internal pressure thrust can be significantly increased, so that very big internal pressure thrust significantly increases again, causes the interface portion stress shape of filter core
State further deteriorates.Now, user wishes that the water flow of reverse osmosis water purifier is the bigger the better, and the water outlet of big flow needs water purification
Runner has biggish cross-sectional area mating with it, could reduce resistance to water-flow, and it is smooth to use water flow, to realize that big flow is discharged it
Purpose.However, present this reverse osmosis fast-connection filter element structure, cannot be well adapted for this requirement, cause bottleneck.
Therefore there is also improved spaces for the three interface quick-connected filter element structure of same end of well-known technique.In view of the above drawbacks, this hair
Bright creator obtains the present invention by prolonged research and practice finally.

Slot matched with bolt is arranged in filter cartridge seat and with the connection part suitable position of three interface modules of end respectively, at same end three in part
Bolt is inserted by interface module again after being packed into filter cartridge seat, thus by the two positive connection.
The intake-outlet of three interface module of same end of the invention is located at the side of cone cell fixing ring, cone cell profile seal
The shape of two circles on circle is identical and size is not identical, because the intake-outlet with three interface modules of end is not concentric structure, therefore
Under the premise of ensuring that water inlet passageway cross-sectional area is sufficiently large, interface great circle size still can be designed smaller, such as
When circle is round, such as axis of great circle d can be designed as 28mm, axis of small circle is designed as 19mm, core pipe interior diameter is (net
Aquaporin) it is designed to 7mm, because the diameter of the first O-ring seals 18 and 19 diameter of the first circle of cone cell fixing ring are identical,
Can make internal pressure thrust caused by hydrostatic pressure substantially in fast-connection filter element internal balance, thus internal pressure thrust it is substantially all by
Hydraulic pressure on annular projection's area between the big roundlet of cone cell fixing ring generates, because raw water is from membrane module raw water water inlet end
It flows into after membrane module during being flowed out again from membrane module concentrated water water outlet, resistance to water-flow very little, generated pressure drop can neglect
Slightly disregard, it can raw water pressure and concentrated water pressure are approximatively thought equal, the internal pressure thrust of this sample embodiment can be by
Following formula is estimated:
F indicates internal pressure thrust in formula, and unit N, d indicate that axis of great circle, d0 indicate axis of small circle, unit mm, P expression
Hydraulic pressure at intake-outlet, unit MPa.When hydraulic pressure at intake-outlet is 0.6MPa, it can be calculated internal pressure through above formula and push away
Power F is 199N.
To sum up, provided by the invention with three mouthpieces of end, three interface modules of same end, fast-connection filter element and water purifier, it compares
Well-known technique can maximally reduce internal pressure thrust when fast-connection filter element is run in filter core interface.
In addition, the invention shows in filter cartridge seat raw water water route axis and concentrated water water route axis be overlapped, and and filter shaft
Line is vertical, and when water purifier plate of water route plane is vertical with filter core axis, this structure is conducive to water route and water route in filter cartridge seat
Water route connection on plate, to keep structure simple, compact dimensions, manufacturing cost is reduced.Wherein, the raw water water inlet water in filter cartridge seat
As long as road axis and concentrated water water outlet water route axis and filter core axis intersection point having the same, it is not necessary to emphasize raw water in filter cartridge seat into
Water water route axis and concentrated water water outlet water route axis must be overlapped, this when water purifier plate of water route plane is vertical with filter core axis
Structure equally also has the above advantages.
The smallest cross-section area of raw water runner and concentrated water runner, the prior art and the present invention can be designed bigger,
Meet technical requirements, in other words, this is not technical problem.Technical problem is with the water purification channel in three interface fast-connection filter elements of end
