Technical Field

The invention relates to the technical field of filters, in particular to an environment-friendly engine oil filter.

Background

The engine oil filtering means that the quality of engine oil, such as viscosity, acid value, antioxidant content and the like, is ensured besides filtering, and the indexes are degraded under a long-term high-temperature operation environment, so that vehicles need to be periodically changed with engine oil to ensure that the indexes are within an acceptable range. If the engine oil directly enters the lubricating oil path without passing through the engine oil filter, sundries contained in the engine oil are brought to the friction surface of the kinematic pair, the abrasion of parts is accelerated, and the service life of the engine is shortened. The engine oil filter is used for filtering impurities, colloid and moisture in engine oil and conveying clean engine oil to each lubricating part, and during the working process of an engine, metal abrasive dust, carbon deposit oxidized at high temperature, colloidal precipitate, water and the like are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids, keep the lubricating oil clean and prolong the service life of the lubricating oil.

Chinese patent discloses an oil cleaner, and patent application number is CN201110175132.4, including filter core, bypass valve, shell, wherein the filter core sets up in the shell, the shell includes interconnect's lower casing and filter core lid, wherein, the bypass valve sets up on the filter core lid, will filter before dirty oil the passageway and filter after seal between the passageway of cleaning oil.

Although the above-mentioned patent uses a single microporous filter paper as the filter material, the bypass valve is easy to be blocked, needs to be replaced frequently, has a short service life, and after the blockage, in order to ensure the smooth circulation of the engine oil, the bypass valve is opened by the engine oil under the pressure of the oil pump, the engine oil flowing in can not be filtered by the filter paper, and the impurities remained in the filter paper after being filtered can be flushed into the engine again, which causes secondary abrasion to the engine, meanwhile, after most of the filter oil filters in the prior art are used for a period of time, the filter element in the engine is blocked, which results in poor filtering effect or can not be used continuously, and the whole filter oil filter needs to be replaced generally, the changed oil filter is treated as waste, and the change mode not only causes resource waste and prevents the resource from being reused, but also causes certain pollution to the environment and is not environment-friendly enough.

Therefore, an environment-friendly engine oil filter is provided.

When the filter plate is used, although impurities on the magnet can be cleaned and collected by the cleaning mechanism, the impurities on the filter plate cannot be cleaned, when too much impurities are filtered on the filter plate, the filter holes can be blocked, and the filter effect of the filter plate is influenced. When the stop work, the inside machine oil that no longer gets into of casing, the inside temperature drop second gasbag reconversion of casing, impurity drop through the passageway at the upper end surface of magnet, are cleared up to the collecting tank inside together with the adsorbed impurity of magnet inside to guarantee the filter effect of totality, through the practicality of totality.

Preferably, the second complementary unit includes connecting block, spliced pole, torsional spring, closing plate and ejector pad, the one end fixedly connected with spliced pole of closing plate, the spliced pole surface encircles the torsional spring, the medial surface fixed connection of torsional spring one end and closing plate, the other end of torsional spring and the medial surface fixed connection of closing plate, the spliced pole both sides are rotated and are connected the connecting block, the surface lower extreme of filter is close to intermediate position fixed mounting ejector pad.

When the filter plate moves forwards, the push block is driven to extrude the sealing plate to overcome the elasticity of the torsion spring, so that the sealing plate blocks the collecting tank, when the filter plate stops working, the temperature in the shell does not enter the engine oil any more, the temperature in the shell is reduced, the expanded gas in the shell returns to the original state, so that the first air bag returns to the original state, the filter plate moves backwards, the push block does not produce extrusion force on the sealing plate any more, the torsion spring drives the sealing plate to move upwards, the collecting tank is reopened, and impurities are cleaned to the collecting tank by the cleaning plate.
