Specifically, the filter housing 2 is an essential part of the entire apparatus. The oil filter device 3 is mainly used for filtering engine oil. The oil cooler 4 can reduce the temperature of engine oil in engine oil, and then avoid the high temperature to cause the carbon deposition, be equipped with oil inlet 21 on filtering the casing 2, be equipped with check valve 22 in the oil inlet 21, be equipped with wax formula engine oil thermostat 23 in the check valve 22, engine oil can pass through oil inlet 21 pushes open check valve 22, and then get into in wax formula engine oil thermostat 23, because check valve 22 is a check valve, through setting up after the check valve 22, can avoid the engine when not working, engine oil flows out from the internal system, guarantees that there is engine oil to engine lubrication the first time after the engine starts, reduces dry friction, filtering casing 2 surface and being equipped with cooling water route 5.

As shown in fig. 4, the cooling water path 5 includes a water pump mounting position 51, a water path volute 52 is disposed in the center of the water pump mounting position 51, a water path interface 53 is disposed on the water path volute 52, the water path interface 53 is connected with a water inlet water path, a water outlet water path is disposed at the downstream of the water inlet water path, after the cooling liquid from the engine water tank passes through the water path volute 52, a part of the cooling liquid enters the engine through the engine adapter to cool the engine, a part of the cooling liquid flows through the water inlet water path of the oil cooler 4 to the oil cooler 4, engine oil heat is taken away in the oil cooler 4, and the water outlet water path of the oil cooler 4 flows to the water path thermostat, which is a conventional component, and will not be described in detail herein.

Further, as shown in fig. 3, the wax-type engine oil thermostat 23 includes a thermostat valve 231, a thermostat valve hole 234 is provided on the thermostat valve 231, a thermostat spring 232 is provided in the thermostat valve 231, and a thermostat cover 233 is provided at the other end of the thermostat spring 232.

In this embodiment, the wax-type engine oil thermostat 23 includes a thermostat valve 231, a thermostat valve hole 234 is provided on the thermostat valve 231, a thermostat spring 232 is provided in the thermostat valve 231, and a thermostat cover 233 is provided at the other end of the thermostat spring 232. When the engine is started, engine oil can push the thermostat valve body 231 to compress the thermostat spring 232, and at the moment, the thermostat valve hole 234 is communicated with the direct oil inlet 21 of the filter element and is not communicated with the oil inlet of the engine oil cooler 4, and the engine oil directly enters the engine oil filter element 31 system without cooling so as to accelerate the temperature rise of the engine oil; when the engine works normally, the temperature of the engine oil rises rapidly, and when the temperature exceeds a certain temperature, 100 ℃ is adopted in the embodiment, the temperature can be set according to the actual working requirement of the engine, and the range is generally 90-115 ℃. At this time, due to the reduction of oil pressure, the thermostat spring 232 will push the thermostat valve 231 to move, the thermostat valve 231 plugs the direct oil inlet 21 of the filter element, engine oil passes through the thermostat valve 231, enters the oil cooler 4 from the oil inlet of the oil cooler 4, and enters the oil outlet after being filtered by the engine oil filter element 31. The whole process can ensure that the engine oil temperature is in a reasonable range, thereby reducing the generation of soot, improving the replacement mileage of the engine filter element and engine oil and reducing the maintenance cost of customers.

Further, a service valve 6 is provided on the lower side of the oil filter 31. The service valve 6 is fixed on the filter base 1, when the engine oil filter element 31 is replaced, the service valve 6 is separated from the filter base 1, the service valve and the engine oil are not sealed, engine oil in the filter base 1 can flow back to the oil pan along an oil way, and the filtered engine oil can not be mixed with unfiltered engine oil when the filter element is replaced, so that an engine is better protected.

In this embodiment, the engine oil filter system includes an engine oil filter 31, and a flat top cover 30 connected to the filter housing 2 is provided on the upper side of the engine oil filter 31. After engine oil enters the engine oil filter element 31 system, the engine oil is filtered by the engine oil filter element 31, the filtered engine oil enters the main oil port through the central pipe, and then the filtered engine oil enters the engine to lubricate parts of the engine so as to ensure stable and efficient operation of the engine. If the engine oil temperature of the engine oil is too low or the filter core life expires, the trafficability of the filter core is greatly reduced, when the pressure of the inner side and the outer side of the filter core reaches a certain pressure difference, the pressure difference is 250+/-50 kPa in the embodiment, and the bypass valve on the upper side of the engine oil filter core 31 is opened, so that part of dirty engine oil enters one side of clean engine oil without filtering, the engine oil of the engine is ensured to be normally supplied, and the engine is prevented from being worn due to insufficient oil supply of the engine. The upper side of the engine oil filter element 31 is provided with the flat top cover 30 connected with the filter shell 2, and compared with the conventional engine oil filter element 31 system provided with an engine oil rotor filter, the engine oil filter mainly can rotate at a high speed, so that clean engine oil in the engine oil rotor filter, which is remained by impurities in the engine oil, can enter an oil return port through an engine oil return oil way, and the arrangement of the engine oil rotor filter increases the design verification and manufacturing cost between the engine oil rotor filter and the engine oil filter element 31 system and increases the engine oil rotor filter. Accordingly, the present application proposes to dispense with the corresponding replacement of the rotor filter with a flat top cap 30, it being understood that the corresponding connection between the engine oil rotor filter and the engine oil filter cartridge 31 system is also omitted correspondingly. Compared with an oil filter provided with an oil rotor filter, the oil filter provided by the application is simple in structure, convenient to manufacture, good in reliability, stable in operation, not prone to damage and capable of meeting system requirements.

Further, the flat top cover is made of PA66-GF35 reinforced nylon plastic material. Specifically, the flat top cover is made of PA66-GF35 reinforced nylon plastic material, and has stronger impact resistance, stronger wear resistance, stronger rigidity and stronger toughness.

Further, the thickness of the flat top cover is 2.5mm-3mm. Specifically, when the thickness of the flat top cover is lower than 2.5mm, the performance of the flat top cover cannot meet the performance of the filter, and in the long-term use process, the filter is likely to fail or the engine oil filtering effect cannot be normally realized. And when the thickness of flat top cap is higher than 3mm, its cost is increased correspondingly, in the preferred embodiment that this application provided, the thickness of flat top cap is preferably 2.7mm, can satisfy whole car filtration system's requirement, reduces weight and saves cost.

Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
