Abstract

A combined type oil filter relates to oil filters. The invention aims at solving the problem of poor manufacturability and interchangeability in the prior art. The combined type oil filter comprises a split type shell (1), a filter element (2) and a filter element bracket (3), wherein the filter element (2) and the filter element bracket (3) are arranged in the shell; adhesive layers (7) are fixedly arranged at the upper and lower ends of the filter element (2); the filter element bracket comprises an upper baffle (31), a central post (32) provided with oil through holes on the side walls anda lower baffle (33); the filter element is sheathed on the central post between the upper baffle and the lower baffle; convex rings (8) are arranged on the adhesive layers at the upper and lower endsof the filter element respectively; and ring-shaped grooves (9) matched with the convex rings are respectively arranged on the positions of the upper baffle and the lower baffle corresponding to the convex rings on the filter element. The upper and lower baffles in the design are of flat-plate type structure and can arbitrarily adapt to the filter elements with different specification sizes; therefore, the manufacturability and interchangeability are good. The combined type oil filter has the advantages of simple structure, low cost, convenient operation and safe and reliable use, and has broad application prospect.

Description

technical field [0001] The invention relates to an engine oil filter. Background technique [0002] At present, most of the housings of commercially available oil filters are one-piece inseparable steel structures, which are discarded as a whole after use, resulting in a lot of waste. The utility model patent (ZL200420077865.X) with the name of the invention "Replaceable Oil Filter" discloses a cartridge-replaceable oil filter. The problem of massive waste. The filter element is a stacked paper filter element, which is installed in the card edge of the upper cover and the lower bottom of the filter element. For different specifications and sizes, the upper cover and the lower bottom of the filter element need to be equipped with different specifications, and there are problems of poor manufacturability and interchangeability. . Contents of the invention [0003] In order to solve the problems of poor manufacturability and interchangeability in the prior art, the inventi...
