Summary of the invention

Technical problem to be solved in the utility model provides a kind of demand that people drink high-quality water that can satisfy at above-mentioned prior art present situation, again the fast-connecting type filter core that can freely install, safeguard in various occasions.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: comprise housing and filtrate, it is characterized in that described housing includes the inner housing of shell body and the described filtrate of device, inner housing is inserted in the shell body, and the inner housing bottom and the shell body that have exhalant canal are sealed and matched the interior loam cake that is provided with water inlet that is stamped suitable for reading of inner housing; The sealed attachment suitable for reading of described shell body has an outer loam cake, the bottom of shell body be provided with by the intake tunnel that constitutes between the inside and outside housing and on the water inlet that communicates of the water inlet water route that covers and the delivery port that communicates with the exhalant canal of inner housing lower end.

Described water inlet and delivery port all can with standard 1/4 " the quick union coupling is connected.

Described inner housing lower end is the connection-peg that periphery is provided with the sealing ring draw-in groove, correspondingly is provided with the internal plug seat of pegging graft by sealing ring sealing coupling with this connection-peg in described shell body.

Pass through thread connection between described shell body and the outer loam cake, and the connection place is provided with sealing ring.

Described its above and below of filtrate that is contained in the inner housing is respectively equipped with the upper and lower baffle plate that can supply water and pass through, and is provided with PP web and nonwoven respectively at the below of overhead gage and the top of lower baffle plate.

Compared with prior art, advantage of the present utility model is: can be with 1/4 by filter core provided by the utility model " the PE running water pipe is by standard 1/4 " quick union is connected fast, structure is flexible, and more renew cartridge is quick, convenient, and the filter housing after the use can also recycling.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the structural representation that the inner housing of filtrate is housed.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, this filter core mainly includes a shell body 3, an inner housing 4, one outer loam cake 1, one interior loam cake 2 and filtrate 5 etc., wherein:

Described inner housing 4 is designed to cylindric, and there is a connection-peg 12 that has an exhalant canal its bottom, can be plugged in the spliced eye 10 of bottom in the shell body.Have two sealing ring draw-in grooves on the periphery of connection-peg 12, but setting-in O RunddichtringO 11.The connection-peg 12 of described inner housing 4 bottoms is plugged in the spliced eye 10 of bottom in the shell body, and splicing position is promptly by these two O RunddichtringOs, 11 sealings.The open-top of inner housing 4, its loam cake have described interior loam cake 2, and offer the water inlet that can supply water and enter in the top of interior loam cake 2.

Described filtrate 5 is contained in the inner housing 4, and the overhead gage 14 and the lower baffle plate 13 that are provided with an AND DEWATERING FOR ORIFICE STRUCTURE respectively at the top and the below of filtrate 5, and also is respectively equipped with PP web 16 and nonwoven 17 between upper and lower baffle plate and filtrate.

Described shell body 3 is designed to hold the cylindric of described inner housing, and the open-top of this shell body, its loam cake have described outer loam cake 1.Described outer loam cake 1 spins with shell body 3 employing spiral shells and connects, and is provided with O RunddichtringO 15 between the two.The bottom of shell body is provided with a water inlet 8 and a delivery port 9, wherein water inlet 8 communicates with intake tunnel 6 water routes that are made of the slit between the outer wall of the inwall of shell body and inner housing, and the water inlet at loam cake 2 tops is communicated with filter core inside in being arranged on, and delivery port 9 is communicated with the exhalant canal 7 of inner housing bottom connection-peg.And in order to realize and 1/4 " the quick of PE running water pipe be connected, described water inlet 8 and delivery port 9 all be designed to can with standard 1/4 " the quick union coupling is connected.

During assembling, inner housing 4 integral body that filtrate 5, interior loam cake 2 are housed are inserted in the shell body 3, be packaged as a whole with outer loam cake 1 then, this filter cartridge construction can be realized the quick assembly and disassembly of inside and outside housing, is beneficial to very much the replacing of filter core and the utilization again of filter housing.

During use, 1/4 " the PE running water pipe is by standard 1/4 " water inlet 8 of quick union and filter core joins, running water flows to the slit between the inwall of the outer wall of inner housing and shell body through water inlet 8, enter inner housing inside through the interior water inlet of going up tops again, the filtrate of flowing through from top to bottom, filtered water behind media filtration is flowed out by delivery port 9, can directly drink for people.

In the time of if a plurality of series connection of the utility model will being used, then as long as with the water inlet and 1/4 of first filter core " the PE pipe joins, and the water inlet of its delivery port and back one filter core joins, and in this mode of joining, the delivery port of last filter core is the pure water delivery port.
