The embodiment of the same end of outer barrel 2 is arranged in water inlet 23 and the second water inlet 23.
As shown in figure 5, the first water inlet 21, outlet pipe 22 are arranged in the centre of the end of outer barrel 2, and the first sealing
Anchor ring 25 surrounds the first water inlet 21, also, the cylinder 11 of inner cylinder 1 is inserted into the first sealing ring surface 25.
Moreover, the second water inlet 23 and the second water outlet 24 are also disposed at this side end, and it is arranged opposite the
The outside of one water inlet 21, the second water inlet 23 are located at outside the second sealing ring surface 26, and the second water outlet 24 is located at the second sealing ring
In face 26.
As shown in fig. 6, mounting base 5 is in order to avoid blocking the cooperation of the first sealing ring surface 25 with cylinder 11, mounting base 5 is right
Position is answered to be provided with perforation, and to third sealing ring surface 52 is extended between the first sealing ring surface 25 and cylinder 11, third is sealed
Anchor ring 52 is clamped and fixed between the first sealing ring surface 25 and cylinder 11, and respectively at holding sealing.
Mounting base 5 also has detent 53, for carrying out clamping installation for the second filter element body 4.
A kind of composite filter element according to the present invention, by double-layer barrel structure setting, inner cylinder 1 is mounted in outer barrel 2,
Inner cylinder 1 also keeps sealing between outer barrel 2 simultaneously, is being formed with each other between inner cylinder 1 and outer barrel 2 in inner cylinder 1
Between the first filtration system and the second filtration system that seal；Inlet and outlet are respectively provided with simultaneously with two filterings is
System is cooperated；Meanwhile first filter element body 3, inner cylinder 1, the second filter element body 4 and each layering of outer barrel 2 socket setting,
The composite filter element structure for forming multilayer, so the outer wall of inner cylinder 1 is also used as the wall of the second filtration system, in outer barrel 2
Wall surrounds the space for foring the installation of the second filter element body 4, while also allowing first water inlet of the inner cylinder 1 on outer barrel 2
21 and first water outlet 221 distance it is closer, it is not necessary to the water route of special setting connection the first water inlet 21 and the second water outlet 24
It is connected to inner cylinder 1；The filtration channel with the cooperation of the first filter element body 3 is formed in inner cylinder 1, the channel is in 1 shape of inner cylinder
At third water inlet 112 and third water outlet 111, inner cylinder 1 by the first water inlet 21 and the first water outlet 221 and second into
The separation at the mouth of a river 23 and the sealing of the second water outlet 24, third water inlet 112 and third water outlet 111 and the first water inlet 21 and the
One water outlet 221 is respectively communicated with, and forms the other parts point with outer barrel 2 for being individually for the filtering setting of the first filter element body 3
The first filtration system separated.
It preferably, further include non-return valve, the non-return valve is arranged at first water inlet 21, the first water outlet
221, the second water inlet 23, the second water outlet 24, third water inlet 112, third water outlet 111, the 4th water outlet the 51, the 5th go out
One of mouth of a river 332.Non-return valve can prevent the aqueous reflux in water route from forming water attack, can protect lid composite filter element.
The present invention also provides a kind of water purifiers using above-mentioned composite filter element, further include each mistake in connection composite filter element
The pipeline of filter system, first filtration system are post active carbon filtration system, and second filtration system is the filtering of PP cotton
System passes through the piping connection and controls water by PP cotton filtration system and post active carbon filtration system.
Three-level filter system can be arranged in general water purifier, and wherein PP cotton filtration system is generally as prefilter, postposition
Active carbon filtration system is filtered as postposition, so the pipeline setting of the water purifier for using composite filter element of the invention, meeting
The filtering of the second filtration system is first introduced the water into, just can will introduce the first filtration system by the water of the second filtration system filtering later
Filtering.
