Description

Technical Field

[0001] The utility model relates to the technical field of engine oil filters, in particular to an engine oil filter sealing structure. Background Technique

[0002] Engine oil filters are classified into replaceable type, spin-on type, and centrifugal type according to their structures; and are divided into full-flow type and bypass type according to their arrangements in the system. The filtering materials used in engine oil filters include filter paper, felt, metal mesh, non-woven fabric, etc. The function of the engine oil filter is to filter harmful impurities in the engine oil from the oil pan and supply clean engine oil to moving pairs such as the crankshaft, connecting rod, camshaft, supercharger, piston ring, etc., playing the roles of lubrication, cooling, and cleaning, so as to extend the service life of these components. Before the 1980s, most of the domestic engines used replaceable engine oil filters. The filter of this structure places the filter element and other parts, such as springs, sealing rings, etc. into a metal shell, and connects and fixes the shell filter element, etc. to a metal filter base through a pull rod. The advantage of the replaceable engine oil filter is low usage cost, and only the filter element needs to be regularly maintained and replaced. The disadvantages are that there are too many sealing points, parts may be missed during maintenance and replacement of the filter element, which is likely to cause leaks, and the replacement is troublesome. Since the early 1980s, spin-on filters have gradually been recognized and selected by domestic main engine factories. The characteristics of spin-on filters are that they are internally provided with a check valve and a bypass valve, and there is only one sealing point, and the whole is replaced, greatly improving the sealing performance and being easy to replace. Most of its filter element materials use imported filter paper, so it has high filtration efficiency, small flow resistance, and long service life. The existing patent, patent publication number CN105351127A, discloses a sealing structure of a diesel engine filter, including a filter body, and a rubber ring installation groove is provided on the filter body. The cross-section of the rubber ring in the rubber ring installation groove is a trapezoidal structure with a narrow upper part and a wide lower part. Compared with the prior art, the present invention has the following advantages: (1) The rubber ring with a rectangular cross-section is reformed into a rubber ring with a trapezoidal cross-section, reducing the contact surface area between the rubber ring and the filter base, thereby increasing the pressure and improving the pressure borne by the rubber ring. (2) Without changing the structure of the installation groove on the filter base, only improving the structure of the rubber ring can reduce costs and is easy to process.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: In the actual application process, positioning and sealing operations need to be carried out on it. If it is not convenient to carry out positioning and sealing operations, the convenience of use of this structure will be affected during subsequent use, reducing the use efficiency of this structure.
