Preferable sealing, so that the water flow of 40 two sides different quality of the second filtering group is not easy that crossfire occurs in bottom.
In addition, gear 441 housing of rubber ring, on outlet pipe 60, the outer periphery of gear rubber ring 441 is kept off in the outer circumferential of end plate 44.
Gear rubber ring 441 is arranged at the end plate 44 of outlet pipe 60, may go out when reducing gluing between the second filtering group 40 and end plate 44
Existing excessive glue phenomenon.It is nested between gear rubber ring 441 and outlet pipe 60, is easily worked outlet pipe 60 in production, it can be to half-open
Mould, extensive to manufacture, manufacturability is high.
It is understood that the utility model composite filter element component 100, the second filtering group 40 is located in inner tube 30, and
Inner tube 30 is located in the first filtering group 20, that is to say, that the first filtering group 20, inner tube 30 and the second filtering group 40 are successively embedding
Set setting, can make full use of the space in the first filtering group 20.
First filtering group 20 and the second filtering group 40 are spaced apart compound setting in shell 10 using inner tube 30, two mistakes
It will not be interfered with each other when being filtered between filter group, and the space for accommodating a filter core originally can accommodate two mistakes simultaneously
Filter group saves the overall occupied space of the first filtering group 20 and the second filtering group 40, so that composite filter element component 100 is whole
It is compact-sized, integrated degree is high, is conducive to reduce structure size.
The utility model has the outlet pipe 60 of 44 structure of above-mentioned gear rubber ring 441 and end plate, may make outlet pipe 60 itself
During fabrication, it is separated with gear rubber ring 441, does not influence outlet pipe 60 and be half-and-half opened, extensive to manufacture, manufacture is completed to facilitate group
Whole outlet pipe 60 is dressed up, then is assembled together with gear rubber ring 441, the efficiency of processing and manufacturing increases substantially.Keep off rubber ring 441 also
End plate 44 and the second filtering group 40 can be made in gluing, reduce the glue overflowed from gap between the two, prevent the glue overflowed
Influence filter effect.
As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 8, the second filtering group 40 is arranged around outlet pipe 60, and end plate 44 is formed as annular slab
And be connected on the end face of the second filtering group 40, gear rubber ring 441 includes: connection ring and sealing ring, sealing ring be formed as tubular and
It covers in the outside of the second filtering group 40 and end plate 44, connection ring is from one end edge far from the second filtering group 40 of sealing ring along diameter
To extending internally.
Connection ring can be closed further when sealing between the second filtering group 40 and end plate 44 to circumferential excessive glue.Sealing ring then may be used
To increase the contact of connection ring with end plate 44, prevent glue from overflowing from the gap of 44 junction of connection ring and end plate.Under sealing ring
Week, the internal perisporium of sealing ring sealed against the periphery wall of first filter membrane 42 along the outer periphery for connecting connection ring, and gear rubber ring 441 is broken
Face is formed as L shape.
Optionally, as shown in figure 16, end plate 44 is equipped with card convex 440, and gear rubber ring 441, which is equipped with, to be cooperated with card convex 440
Card hole (not shown go out).Card convex 440 and card hole cooperation can make to keep off rubber ring 441 covering on the basis of outlet pipe 60, further block
On the end plate 44, make to keep off rubber ring 441 convenient for being assemblied on outlet pipe 60, and increase connection reliability and assembly it is simple
Property.After disassembling simultaneously, gear rubber ring 441 is also used as an independent component and uses, and so both will not influence the second filtering group
40 gluing effect, will not influence the filter effect of the second filtering group 40, and manufacturability is greatly improved.
Optionally, it outwardly protrudes to form protrusion 442 at the corresponding each card hole of gear rubber ring 441, gear rubber ring 441 can be facilitated in this way
Positioning is contacted with external component.
Advantageously, outlet pipe 60 is integrated injection molding part, and integrated injection molding goes out end plate 44 on outlet pipe 60.End plate 44
With 60 integrated injection molding of outlet pipe, it is easy to use mold manufacture, and end plate 44 has enough bearing capacitys, is not easy from water outlet
It is isolated and fallen off on pipe 60.It prevents that skew occurs during because of long-time use.
In some embodiments of the utility model, as shown in figure 8, inner tube 30 is detachably arranged in built-in filter material installation cavity
It is interior, and inner tube 30 is formed as the closed tubulose of the open at one end other end, inner tube 30 by built-in filter material installation cavity be partitioned into inner cavity and
Exocoel, the second filtering group 40 be located at it is interior intracavitary, due to built-in filter material installation cavity side open wide, water flow not only can pass through first
Filtering group 20 can also enter inner cavity by the opening of built-in filter material installation cavity, and pass through to be filtered by the first filtering group 20
Second filtering group 40 is filtered, and makes to form series relationship between the first filtering group 20 and the second filtering group 40.
In some embodiments of the utility model, as shown in Figures 2 and 4, the first filtering group 20 is reverse osmosis filter core, the second mistake
Filter group 40 is initial filter filter core, and the wall thickness of initial filter filter core is greater than 10mm.
In some examples of the utility model, the second filtering group 40 is to be rolled by non-woven fabrics, polypropylene layer, carbon fiber
Reel, service life is longer.When the filtering for tap water, silt, iron rust and chlorine residue can be tentatively removed.Certainly, second
Filtering group 40 can also be rolled only by one of or two kinds of materials filtering layer, be not particularly limited here.
The filter effect of initial filter filter core is related with the wall thickness of initial filter filter core, and the thicker filter effect of the wall of initial filter filter core is better,
When the wall thickness of initial filter filter core is greater than 10mm, user can satisfy to the filtering requirement of water flow.The filter effect of reverse osmosis filter core
It is related with the area of the filter membrane of winding.Therefore, built-in filter material installation cavity is limited in reverse osmosis filter core, and initial filter filter core is located at
