The intermediate duct 8 takes the shape of the letter U, including the first connection end and second being connected with the exit of first joint 4
Connection end.The effect of the intermediate duct 8 is the connection joint 5 of the first joint 4 and second, guides the liquid from the mistake
Filter 1 flow to the micro element 2.
- the second joint 5
Second joint 5 includes connection end and exit, and its connection end is connected with the first end of the micro element 2, its
Exit is connected with the second connection end of the intermediate duct 8.Second joint 5 can use and 4 identical or phase of the first joint
As structure.
Connecting portion 3 described in this improvement embodiment divides for three parts, by the way of joint, fast and easy assembling and dimension
Shield, such as when carrying out replacing to the filter 1 and safeguarding, without being dismantled to micro element 2.
As the further improvement of above-mentioned filter, the filter also includes：
- the three joint 6
3rd joint 6 includes connection end and exit, and its connection end is connected with the input of the filter 1, its
The import 9 of exit and exterior line connects.3rd joint 6 can use and 4 same or analogous structure of the first joint.
- the four joint 7
4th joint 7 includes connection end and exit, and its connection end is connected with the second end of the micro element 2, its
The outlet 10 of exit and exterior line connects.4th joint 7 can use and 4 same or analogous structure of the first joint.
Connection of this improvement embodiment to the filter and exterior line limits, respectively using the 3rd joint 6
It is connected with the 4th joint 7 with the import 9 and outlet 10 of the exterior line.The flow route of liquid is now to pass through the exterior tube
The import 9 on road flows into the filter 1, then flows through the intermediate duct 8, then flows into the micro element 2, most afterwards through described outer
Flow out the outlet 10 of portion's pipeline.So described filter can be used as an entirety to carry out installing/dismounting behaviour with exterior line
Make, realize Integration Design.
As the further improvement of above-mentioned filter, the joint 7 of the second joint 5 and the 4th surrounds the micro element 2
First end and the second end form the first lug boss and the second lug boss.First lug boss and the second lug boss grip
The filter 2 of the joint 6 of first joint 4 and the 3rd has been installed.This improvement embodiment is made to the fixed form of the filter 1
Limit, i.e., after described filter 1 connects the joint 6 of the first joint 4 and the 3rd, as one by fixed global facility by
The joint 7 of second joint 5 and the 4th grips.The realization of the present embodiment has a premise, i.e., described second joint 5 and
Four joints 7 are outstanding relative to the horizontal plane of the micro element 2, the first lug boss and the second lug boss formed, when described
When filter 1 is positioned on the micro element 2 together with the joint 6 of the first joint 4 and the 3rd, first lug boss
The external end edge of the joint 6 of the first joint 4 and the 3rd can be clamped with the second lug boss.In order to be better achieved to the filtering
Device 1 grips, when filter assembling finishes, between the interior ora terminalis of the joint 7 of the second joint 5 and the 4th
Distance is equal to the distance between external end edge of the joint 6 of the first joint 4 and the 3rd.

The exit of joint 7 is provided with hole, and the intermediate duct 8 and exterior line are connected by the hole.This improvement embodiment is to respectively connecing
The exit of head limits, and the exit of each joint is provided with hole, and pipeline inserts in the hole connection realized with joint.According to
The active position of different joints, each joint are connected with intermediate duct 8 and exterior line respectively.Above-mentioned technical characteristic allows pipeline
Flexible assembling is carried out with joint so that the installing/dismounting of the filter is more convenient.
As the further improvement of the filter, honeycomb net type is formed by least two materials inside the filter 1
Filtration.This improvement embodiment is further qualified to the internal structure of the filter 1, is at least made up of two kinds of materials,
Filtration is honeycomb net type, i.e., in netted honeycomb.
As the further improvement of the filter, the filter also includes：
- encapsulation part
The micro element 2, filter 1 and connecting portion 3 are encapsulated in inside it by the encapsulation part, form a closing space.
The encapsulation part can be covered in the plastics package of the filter, and in the exterior line import 9 and exterior line
Tying at 10 is exported, so described filter only allows liquid to be passed in and out by exterior line, will not enter the table of miscellaneous part
In the gap of face.The encapsulation part can also be formed to the filter and protected, and prevented the interference of foreign matter, avoided being corroded property
Material corrodes.
As the further improvement of above-mentioned filter, colloid is filled in the closing space.After filling colloid, the mistake
Filtering between the outer surface of device and the encapsulation part does not have air, forms effective sealed environment so that the liquid is successfully
Flow into the filter 1.
It should be noted that embodiments of the invention have preferable implementation, and not the present invention is made any type of
Limitation, any one skilled in the art change or are modified to possibly also with the technology contents of the disclosure above equivalent effective
Embodiment, as long as without departing from the content of technical solution of the present invention, above example is made according to technical spirit of the invention
