Description

The dual filtering type filter cleaner

1, technical field

The utility model relates to a kind of Vehicular liquid filtrating equipment, specifically a kind of dual filtering type filter cleaner.

2, technical background

Present Vehicular cleaner mainly comes machine oil is filtered by filter paper, enter the iron foam that contains normal wear in the machine oil of filter cleaner by motor, these iron foams can stop up the filter paper in the filter cleaner, when filter paper can not normal filtration, machine oil can directly enter motor by bypass valve, the machine oil that contains the iron foam can cause very big wearing and tearing to motor after entering motor, serious reduction working life of motor and the working life of filter cleaner.

3, summary of the invention

The purpose of this utility model is at above deficiency, and the dual filtering type filter cleaner of a kind of long service life, good filtration effect is provided.

The technological scheme that its technical problem that solves the utility model adopts is: be provided with filter paper in the shell, the inboard of filter paper is provided with spiral net, the above and below of filter paper is respectively arranged with upper end cap and lower end cap, be with the magnetic filter that has oil inlet hole on the cylindrical of upper end cap, upper end cap the top be provided with the hush panel that has oil inlet hole, the center of hush panel is the spiral oil outlet, and the top, center of lower end cap is provided with bypass valve; Be provided with inner seal ring between the interior circle of upper end cap and the hush panel, be provided with exterior seal ring between hush panel and the shell.

Dual filtering type filter cleaner of the present utility model is compared with prior art, has characteristics such as reasonable in design, simple in structure, long service life, good filtration effect, thereby, have good value for applications.

4, description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is the structural representation of dual filtering type filter cleaner.

5, embodiment

Explain below with reference to Figure of description dual filtering type filter cleaner of the present utility model being done.

Dual filtering type filter cleaner of the present utility model, its structure is to be made of shell 12, filter paper 5, bypass valve 7, upper end cap 3 and lower end cap 8, be provided with filter paper 5 in the shell 12, the inboard of filter paper 5 is provided with spiral net 6, the above and below of filter paper 5 is respectively arranged with upper end cap 3 and lower end cap 8, be with the magnetic filter 4 that has oil inlet hole 13 on the cylindrical of upper end cap 3, upper end cap 3 the top be provided with the hush panel 2 that has oil inlet hole 9, the center of hush panel 2 is a spiral oil outlet 11, and the top, center of lower end cap 8 is provided with bypass valve 7; Be provided with inner seal ring 10 between the interior circle of upper end cap 3 and the hush panel 2, be provided with exterior seal ring 1 between hush panel 2 and the shell 12.

During use, the magnetic filter that is provided with in the enclosure can adsorb the iron foam that engine scuffing produces, these iron foams can be attached to stop up filter paper on the filter paper, machine oil is through secondary filter, also can not enter motor and damage motor with machine oil, both effectively prolong the service time of filter paper, also increased the working life of filter cleaner.

Its processing and fabricating of dual filtering type filter cleaner of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.

Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
