Abstract
Description
Technical Field
[0001] The utility model relates to the field of oil filtration, in particular to a diversified oil filtration device. Background Art
[0002] Currently, excessive carbon emissions have led to global warming, melting glaciers, frequent global extreme weather, and continuous threats to human life. All countries are calling on the world to advocate a low-carbon life. As a large country with a large population in the world, China has a crucial significance for low-carbon travel. The country strongly promotes the national VI emissions to reduce the pressure of world carbon emissions. Therefore, there are higher requirements for the design and development of internal combustion engines. Correspondingly, the requirements for the filtration system of internal combustion engines have also been improved.
[0003] The oil filter is matched with a rotor filter element. There are two small holes at the bottom of the rotor filter element, and the axes of the two small holes have a certain angle. When high-pressure oil enters the rotor filter element, a rotating air flow will be generated when the high-pressure flow passes through the small holes at the bottom of the rotor filter element, thereby driving the rotor filter element to rotate. When the rotor filter element rotates at a high speed (8000 - 10000 r / min), the centrifugal force will make the impurities in the oil adhere to the inner wall of the rotor filter element, playing a better filtering role, so as to better meet the lubrication and heat dissipation requirements of each component of the engine. However, the rotor filter element also has disadvantages. The design and manufacturing cost is expensive, and the production cycle is relatively long.
[0004] In the prior art, in some foreign countries, the requirements for carbon emissions cannot meet the living standards, and only meeting Euro V is sufficient. Although the traditional oil filter can fully meet the conventional use, the intervention of the rotor filter element will generate a large amount of costs. First of all, the diameter and position accuracy requirements of the two small holes of the rotor filter element are very high because it is necessary to make the rotor filter rotate rapidly under a certain pressure to throw out the impurities in the oil. Therefore, the manufacturing difficulty and scrap rate of the rotor filter element are relatively high, resulting in a waste of time cost and manufacturing cost, and also playing a certain negative role in carbon emissions in some senses. Therefore, we propose a diversified oil filtration device to solve the problems raised above. Summary of the Utility Model
[0005] The utility model mainly provides a diversified oil filtration device that reduces manufacturing costs.
[0006] To achieve the above object, the utility model adopts the following technical solutions: a diversified oil filter device, including a filter base, a flat-top cover is arranged on the top of the filter base, an oil cooler is fixedly installed at the center of the outer surface of one side of the filter base, a thermostat cover plate is arranged on the outer surface of the front side of the filter base near the bottom side, an oil return cover plate is arranged at the center of the outer surface of the front side of the filter base, rotor filters are fixedly installed at both sides of the inner surface of the filter base, a bypass valve is arranged at the position near the top of the inner surface of the rotor filter, and a sealing ring is fixedly connected to the opposite side of the rotor filter and the filter base.
[0007] Preferably, a guide oil pipe is arranged through the position near the bottom of the center of the inner surface of the filter base. The arrangement of the guide oil pipe can realize being a part of the oil circulation system and help send the oil purified by the filter base to the inside of the engine.
[0008] Preferably, a central pipe is arranged through the opposite side of the guide oil pipe and the rotor filter. The arrangement of the central pipe can provide a channel for the oil to flow.
[0009] Preferably, the flat-top cover and the filter base are connected by a hinge, which is convenient for the user to open the flat-top cover.
[0010] Preferably, the inside of the oil cooler is communicated with the inside of the filter base, and the inside of the rotor filter is communicated with the inside of the central pipe, so that the oil cooler can reduce the temperature of the overheated oil through the coolant.
[0011] Compared with the prior art, the advantages and positive effects of the utility model are as follows:
[0012] 1. In the utility model, through special design, the current two filtering systems of the rotor filter version and the non-rotor filter version can share the filter base mold, which greatly saves the mold design and manufacturing costs. And canceling the rotor filter and the middle top cover also has a very positive significance for the weight of the product itself. Canceling the parts reduces the overall product weight, thereby reducing the engine load, which has very important significance for low-carbon travel.
[0013] 2. In the utility model, since the simplified version of the filter has one less rotor filter, middle top cover and 1 sealing ring than the high-end version, and the filter base height versions share the mold, the die-casting mold cost is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments in the following disclosure specification.
[0023] Please refer to Figures 1 - 6 , the present utility model provides a technical solution: a diversified oil filter device, including a filter base 1, a flat top cover 2 is arranged on the top of the filter base 1, an oil cooler 3 is fixedly installed at the center of the outer surface of one side of the filter base 1, a thermostat cover plate 4 is arranged on the outer surface of the front side of the filter base 1 near the bottom side, an oil return cover plate 5 is arranged at the center of the outer surface of the front side of the filter base 1, rotor filter elements 8 are fixedly installed at both positions on the inner surface of the filter base 1, a bypass valve 6 is arranged at a position near the top of the inner surface of the rotor filter element 8, and a sealing ring 7 is fixedly connected to the opposite side of the rotor filter element 8 and the filter base 1.
[0024] As Figure 4 shown, a guide oil pipe 10 is penetrated and arranged at a position near the bottom of the center of the inner surface of the filter base 1. The arrangement of the guide oil pipe 10 can realize being a part of the oil circulation system and help send the oil purified by the filter base 1 to the inside of the engine.
[0025] As Figure 4 shown, a central tube 9 is penetrated and arranged on the opposite side of the guide oil pipe 10 and the rotor filter element 8. The arrangement of the central tube 9 can realize providing a channel for the oil to flow.
[0026] As shown Figure 3 in the figure, the flat top lid 2 is hinged to the filter base 1, which facilitates the user to open the flat top lid 2.
[0027] As shown Figure 1 in the figure, the inside of the oil cooler 3 is communicated with the inside of the filter base 1, and the inside of the rotor filter element 8 is communicated with the inside of the central pipe 9, so that the oil cooler 3 can reduce the temperature of the overheated engine oil through the coolant.
[0028] The usage method and working principle of this device: When in use, as shown Figure 5 in the figure, the black arrow indicates the oil path. When the engine oil reaches a certain pressure, the engine oil will enter the inside of the rotor filter element 8 through the valve of the rotor filter element 8 and spray out from the two small holes at the bottom. Since the axial positions of the two small holes are opposite (the position is as shown Figure 6 in the figure), a centrifugal force will be generated under the action of the high-pressure engine oil, which will cause the rotor filter element 8 to rotate at a high speed, so as to separate the impurities in the engine oil, and make the engine oil cleaner under the combined action of the filter element, thereby reducing the engine load, improving the fuel economy, reducing the carbon emission. At the same time, through the improved design, the two filtration systems of the rotor filter element 8 version and the non-rotor filter element 8 version can share the filter base 1 mold, which greatly saves the mold design and manufacturing costs.
