Abstract

The utility model discloses a filter, which comprises a casing and a filter element arranged in the casing, wherein the casing comprises a lower casing and an upper cover, and the filter element comprises a tubular filter paper body and an annular end cover arranged on one side of the tubular filter paper body. The filter also comprises a filter element fixing piece, and a through hole is formed in the center of the filter element fixing piece. The through hole of the filter element fixing piece is communicated with an oil inlet of the upper cover, and the filter element fixing piece is fixedly connected with the upper cover in a sealing mode relative to the periphery of the outer side of the oil inlet. A plurality of circumferentially-distributed claspers are raised and arranged in position, relative to the lower part of the periphery of the through hole, of the filter element fixing piece; and the claspers are fixedly buckled on inner holes of the annular end cover. The filter element fixing piece is in sealing force fit with the external periphery, relative to the inner holes, of the annular end cover. The upper cover is fixedly connected with the filter element in the sealing mode through the filter element fixing piece, so that glue is not needed, and the erosion of engine oil is avoided. The filter has the advantages of good connecting stability and long service life.

Description

A kind of filter cleaner

Technical field

The utility model relates to a kind of auto parts machinery, specifically refers to a kind of filter cleaner.

Background technique

Thereby filter cleaner is a kind of device that can remove the impurity such as dust, metal granule, carbon precipitates and the coal soot protection motor in the machine oil.At present, the structure of existing filter cleaner comprises housing and is arranged on filter core in the housing, and its middle shell includes lower shell body and loam cake, covers on wherein and is provided with oil inlet pipe, is provided with oil outlet tube on the lower shell body.In addition, existing filter core be shaped as tubular structure, by skeleton and be fixed on the skeleton and consisted of by the filter paper body of the longitudinal folding hollow cylindrical that consists of of filter paper material.

When mounted, filter core generally all is to be fixed on the inwall of loam cake by the glue adhering and sealing, but because glue and machine oil are similarly organic substance, cause filter cleaner when in use, glue is melted erosion by machine oil, causes the appearance between filter core and the loam cake to be leaked, even comes off.Exist rate of fault high, the defective that working life is short.

Summary of the invention

The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, stablizes and provide a kind of loam cake and filter core to connect, and is not subjected to machine oil to corrode filter cleaner.

For achieving the above object, the technical solution of the utility model is to comprise housing and be arranged on the interior filter core of housing, its middle shell includes lower shell body and loam cake, cover wherein and be provided with oil inlet pipe, the position that oil inlet pipe is connected with loam cake is provided with filler opening, be provided with oil outlet tube on the lower shell body, described filter core includes tubular filter paper body and is arranged at the annular end cap of tubular filter paper body one side, also include the filter core fixed block, the center of this filter core fixed block is provided with through hole, the through hole of described filter core fixed block communicates with the filler opening of loam cake, and the outboard peripheries of the relative filler opening of this filter core fixed block and loam cake consist of sealing and are fixedly connected, described filter core fixed block is the protruding snap fit that is provided with many circle distribution in periphery below of its through hole relatively, described snap fit fixed card fits on the endoporus of annular end cap, and this filter core fixed block consists of the sealing pressing drive fit with the outboard peripheries of the relative endoporus of annular end cap.

The outside projection of relative endoporus is provided with O shape sealed muscle on the lower end surface that further setting is described filter core fixed block, is provided with the O shape seal groove with O shape sealed muscle sealing scarf on the described annular end cap.

The outside projection of relative filler opening is provided with annular bead on the inwall that further setting is described loam cake, is provided with the annular groove of fixing with annular bead scarf and ultrasonic welding on the upper-end surface of described filter core fixed block.

The utility model is sealedly and fixedly connected loam cake and filter core by the filter core fixed block, therefore, need not to adopt glue, has avoided the erosion of machine oil, has the connection good stability, the advantage of long service life.

Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
