DETAILED DESCRIPTION

[0026] like Figure 1-4 As shown, the utility model provides a gasoline engine oil filter structure, comprising a housing 101, an oil inlet 102 is provided on one side of the upper end of the housing 101, and an oil outlet 103 is provided on the bottom end of the housing 101;

[0027] The filter element assembly 200 is arranged inside the housing 101, and the filter element assembly 200 includes a cover plate 201, a filter frame 202, a filter plate 203, a filter element 204 and a vibrating rod 205. The cover plate 201 is arranged at the end of the filter frame 202, the filter plate 203 is arranged inside the filter frame 202, the filter element 204 is arranged inside the filter plate 203, and the vibrating rod 205 is arranged inside the filter element 204;

[0028] The cleaning component 300 is arranged at the upper end of the inner part of the housing 101 . The cleaning component 300 includes a push rod 301 , a scraper 302 and a cleaning head 303 . The scraper 302 is arranged at the bottom end of the push rod 301 , and the cleaning head 303 is arranged on the inner side of the scraper 302 .

[0029] Furthermore, in this embodiment, an upper cover 104 is provided at the upper end of the outer shell 101, a push rod 301 is screwed to the bottom of the upper cover 104, the scraper 302 is designed as a circular ring, and at least two push rods 301 are provided on the upper surface of the scraper 302. The design of the scraper 302 facilitates its movement on the outside of the filter element assembly 200.

[0030] In this embodiment, a plurality of cleaning heads 303 are equidistantly arranged on the inner side of the scraper 302. The cleaning heads 303 are screwed to the scraper 302. The cleaning heads 303 are triangular in design and are made of a material selected from silicone rubber, fluororubber or nitrile rubber. The material of the cleaning heads 303 enables them to be squeezed so that they can enter into the gap of the filter frame 202 or the filter hole 206, pushing down the oil impurities that are blocked at this position, thereby cleaning the filter element assembly 200.

[0031] In this embodiment, both ends of the filter frame 202 are screwed to the cover plate 201, the filter frame 202 is sleeved on the outside of the filter plate 203, the filter plate 203 is sleeved on the outside of the filter element 204, the vibration rod 205 is sleeved on the outside of the filter element 204, and the bottom end of the vibration rod 205 is screwed to the outer shell 101.

[0032] In this embodiment, the filter frame 202 is composed of a plurality of annular plates, the outer sides of the annular plates are screwed to a fixing plate, and the outer surface of the filter plate 203 is provided with filter holes 206 , through which the engine oil is filtered.

[0033] In this embodiment, the oil inlet 102 passes through the filter frame 202 and the filter plate 203 and is connected to the filter element 204. A gap is provided between the filter element 204 and the filter plate 203. The oil outlet 103 passes through the outer shell 101 and is connected to the cover plate 201. The engine oil directly enters the filter element 204 through the oil inlet 102. The engine oil enters the filter frame 202 after being filtered through the filter element 204 and the filter plate 203, and flows out from the oil outlet 103 under the cover plate 201 at the bottom of the filter frame 202.

[0034] In addition, in order to prevent oil filtration confusion, the bottom of the filter element 204 and the filter plate 203 are fixed on the cover plate 201, and a sealing strip is set for sealing. The filtered oil can only seep out through the filter hole 206 of the filter plate 203, enter the filter frame 202, and flow out through the oil outlet 103 at the bottom of the filter frame 202. In addition, the annular plate of the filter frame 202 can be set to have a gap or no gap according to the oil output. The one without a gap can be used as above, and the one with a gap needs to be provided with a pipeline for exporting the oil outside the filter frame 202, and the oil seeps out directly from the gap.

[0035] In this embodiment, the filter element 204 is made of a material selected from glass fiber or synthetic fiber, and the filter plate 203 is made of a microporous plastic material. The materials of the filter element 204 and the filter plate 203 facilitate filtering of the engine oil.

[0036] Specifically, the filter structure is connected to the gasoline engine, and the engine oil directly enters the filter element 204 through the oil inlet 102, and after being filtered by the filter element 204, enters the filter plate 203 for filtration, and then enters the filter frame 202, and flows out from the oil outlet 103 under the cover plate 201 at the bottom of the filter frame 202. While the engine oil is being filtered, the vibration rod 205 inside the filter element 204 is started, and the impurities and sediments on the filter screen of the engine oil filter are loosened by the vibration force of the vibration rod 205, and the filtering of the engine oil is promoted;

[0037] After the oil is filtered for a period of time, oil impurities will accumulate in the gaps of the filter assembly. If the filter frame 202 is a structure with gaps, the cleaning assembly 300 is set on the outside of the filter element assembly 200, and the push rod 301 controls the scraper 302 to move up and down, and the cleaning head 303 on the inside of the scraper 302 cleans the filter element assembly 200;

[0038] If the filter frame 202 is designed to be seamless, the cleaning assembly 300 is disposed between the filter element 204 and the filter plate 203. Figure 5 As shown, cleaning heads 303 are provided inside and outside the cleaning plate according to needs, and impurities are hung up by the up and down movement of the cleaning plate to avoid clogging of the filter element assembly 200.

[0039] In addition, since the cleaning head 303 is made of elastic material, the cleaning head 303 is tightly attached to the surface of the component to be cleaned. As the cleaning plate moves up and down, the cleaning head 303 will contact the surface of the component to be cleaned and use its elasticity to scrape the surface of the component to be cleaned, thereby scraping impurities on the filter screen off the surface of the component to be cleaned.

[0040] The components of the utility model, such as the housing 101, the oil inlet 102, the oil outlet 103, the upper cover 104, the cover plate 201, the filter frame 202, the filter plate 203, the filter element 204, the vibrating rod 205, the push rod 301, the scraper 302, and the cleaning head 303, are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
