Description

Technical Field

[0001] This utility model relates to the field of automotive engineering technology, and in particular to an automotive filter. Background Technology

[0002] Automotive filters are important components of car engines and related systems. They are used to filter impurities such as dust, metal particles, and moisture from fuel, engine oil, air, and air conditioning. This prevents impurities from entering the engine or vehicle interior, reduces wear on parts, protects the engine's normal operation, and improves the air quality inside the vehicle. They are key devices for maintaining vehicle performance and lifespan.

[0003] A search revealed that the document with publication number "CN218862703U" mentions "this utility model discloses an automotive filter, including a housing, a filter element assembly and a filter screen inside the housing, the filter screen covering the outer periphery of the filter element assembly, a top cover assembly sealed to the housing above the filter element assembly, an oil outlet and several oil inlets on the top cover assembly, the oil inlets being sealed to the filter element assembly, an oil inlet gap being formed between the upper end face of the filter element assembly and the bottom face of the top cover assembly, the oil inlets communicating with the oil inlet gap, and a spring abutting between the bottom of the filter element assembly and the housing." In use, this design eliminates the need for an inlet check valve, an outlet check valve, and a bypass valve while ensuring normal operation, simplifying the overall structure, facilitating assembly during production, and effectively improving production efficiency. The top cover assembly in this utility model is made of environmentally friendly plastic material using injection molding, which is simpler, faster, and has lower labor costs and energy consumption compared to the traditional stamping process using galvanized metal materials.

[0004] However, during the operation of a car engine, fuel or lubricating oil often contains various impurities, such as dust and metal shavings. If these impurities enter the engine, they will accelerate the wear of parts and affect the engine's performance and lifespan. Traditional car filters usually use a single filter medium, such as ordinary fiber filter paper. Their structure is relatively simple, generally including an outer shell and a built-in filter element. The oil enters from the inlet, is filtered by the filter element, and flows out from the outlet. The filtration effect of this traditional filter is limited. It is difficult to achieve graded and efficient filtration of impurities of different sizes. Moreover, during use, impurities tend to accumulate on the surface of the filter element, leading to increased filtration resistance, affecting the normal flow of oil, and thus reducing the engine's working efficiency.

[0005] Therefore, we provide an automotive filter to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automotive filter includes an outer filter canister with an oil inlet welded to its outer side. An oil filter assembly is installed inside the outer filter canister. The oil filter assembly includes an oil filter frame connected to the inner side of the outer filter canister by a slot. A filter core is disposed in the middle of the oil filter frame. A coarse filter layer is disposed on the outer wall of the filter core, and a fine filter layer is disposed on the inner wall of the filter core. A driven bearing is disposed in the middle of the filter core, and a guide shaft is installed on the upper side of the driven bearing. A canister cap is threaded to the upper side of the outer filter canister. An oil outlet is disposed in the middle of the canister cap. A filter screen is installed in the middle of the oil outlet, and a sealing ring is installed on the lower side of the oil outlet.

[0007] As a further description of the above technical solution: The coarse filter layer and the filter core are bonded together, and the coarse filter layer and the filter core are tightly fitted together. The material of the coarse filter layer is polyester fiber non-woven fabric.

[0008] As a further description of the above technical solution: The fine filter layer and the filter core are bonded together, and the fine filter layer and the filter core are tightly attached. The fine filter layer is made of high-efficiency glass fiber filter paper.

[0009] As a further description of the above technical solution: The inner upper and lower ends of the oil filter frame are connected to bearings with slots. A rotating fan blade is connected in the middle of the bearing. The outer wall of the bearing is welded to the inner wall of the oil filter frame, and the inner wall of the bearing is welded to the rotating fan blade. The rotating fan blade and the oil filter frame form a rotating structure through the bearing.

[0010] As a further description of the above technical solution: The inner wall of the rotating fan blade is provided with a scraper, which is in close contact with the coarse filter layer. The scraper is made of oil-resistant rubber.

[0011] As a further description of the above technical solution: The outer wall of the driven bearing is welded to the inner bottom of the outer tank of the filter, and the inner wall of the driven bearing is welded to the guide shaft. The guide shaft rotates through the driven bearing and passes through the middle of the filter core.

[0012] As a further description of the above technical solution: The filter screen is threadedly connected to the oil outlet, and the filter screen is made of ultra-fine glass fiber filter paper.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes an oil filter assembly. When needed, as oil is injected into the outer tank of the filter through the inlet, the coarse filter layer made of polyester fiber non-woven fabric effectively intercepts large particulate impurities, performing preliminary purification of the oil and isolating them on the surface of the coarse filter layer. When cleaning is required, simply rinse the surface of the coarse filter layer for reuse, extending its service life and reducing contamination of the filter core. After passing through the coarse filter layer and the filter core, the oil undergoes deep purification in the fine filter layer. The high-efficiency glass fiber filter paper effectively intercepts fine particles, ensuring oil purity, extending the overall service life of the filter, and improving vehicle operating efficiency.

[0014] 2. This utility model utilizes an oil filtration assembly. When oil is injected into the outer tank of the filter from the inlet, the oil impacts the rotating fan blades, causing them to rotate along the oil filter frame via a bearing. This accelerates oil flow and improves the filtration efficiency of the coarse filter layer. As the fan blades begin to rotate, a scraper moves with them to effectively remove surface impurities from the coarse filter layer, preventing impurity accumulation. When the oil passes through the filter and flows into the inner core of the filter before exiting from the outlet, it pushes the guide shaft to rotate along the driven bearing. This rectifies the outflowing oil, making the flow more uniform, reducing pressure fluctuations, and potentially enhancing the turbulence of the oil, indirectly improving the stability of subsequent engine fuel supply.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-8 As shown, this utility model provides a technical solution: an automotive filter, including an outer filter canister 1, an oil inlet 2 welded to the outer side of the outer filter canister 1, an oil filter assembly 3 installed on the inner side of the outer filter canister 1, the oil filter assembly 3 including an oil filter frame 301 connected to the inner side of the outer filter canister 1 by a slot, a filter core 302 disposed in the middle of the oil filter frame 301, a coarse filter layer 303 disposed on the outer wall of the filter core 302, a fine filter layer 304 disposed on the inner wall of the filter core 302, a driven bearing 308 disposed in the middle of the filter core 302, a guide shaft 309 installed on the upper side of the driven bearing 308, a canister cap 310 threadedly connected to the upper side of the outer filter canister 1, an oil outlet 311 disposed in the middle of the canister cap 310, a filter screen 312 installed in the middle of the oil outlet 311, and a sealing ring 313 installed on the lower side of the oil outlet 311.

[0019] Furthermore, the coarse filter layer 303 and the filter inner core 302 are bonded together, and the coarse filter layer 303 and the filter inner core 302 are tightly fitted together. The material of the coarse filter layer 303 is polyester fiber non-woven fabric. When it is needed, as the oil is injected into the outer tank 1 of the filter from the oil inlet 2, the coarse filter layer 303 made of polyester fiber non-woven fabric can effectively intercept large particulate impurities, perform preliminary purification of the oil, and isolate them on the surface of the coarse filter layer 303. When it is necessary to clean, simply rinse the surface of the coarse filter layer 303 for reuse, thereby improving its service life and reducing the contamination of the filter inner core 302.

[0020] Furthermore, the fine filter layer 304 and the filter core 302 are bonded together, and the fine filter layer 304 and the filter core 302 are tightly fitted together. The material of the fine filter layer 304 is high-efficiency glass fiber filter paper. When it is needed, after the oil passes through the coarse filter layer 303 and the filter core 302, it will undergo deep purification by the fine filter layer 304. The high-efficiency glass fiber filter paper material can effectively intercept fine particles, ensure the purity of the oil, extend the overall service life of the filter, and improve the operating efficiency of the vehicle.

[0021] Furthermore, the inner upper and lower ends of the oil filter frame 301 are both connected to the load bearings 305 by slots. The load bearings 305 are connected to the middle of the rotating fan blades 306. The outer wall of the load bearings 305 is welded to the inner wall of the oil filter frame 301, and the inner wall of the load bearings 305 is welded to the rotating fan blades 306. The rotating fan blades 306 and the oil filter frame 301 form a rotating structure through the load bearings 305. When oil is injected into the outer tank 1 of the filter from the oil inlet 2, the oil will generate an impact force on the rotating fan blades 306, causing the rotating fan blades 306 to rotate along the oil filter frame 301 through the load bearings 305, thereby accelerating the flow of oil and improving the filtration efficiency of the coarse filter layer 303.

[0022] Furthermore, a scraper 307 is provided on the inner wall of the rotating fan blade 306. The scraper 307 is in close contact with the coarse filter layer 303. The scraper 307 is made of oil-resistant rubber. When the rotating fan blade 306 starts to rotate, the scraper 307 will move with the fan blade to effectively scrape off the surface impurities of the coarse filter layer 303 and prevent impurities from accumulating.

[0023] Furthermore, the outer wall of the driven bearing 308 is welded to the inner bottom of the filter outer tank 1, and the inner wall of the driven bearing 308 is welded to the guide shaft 309. The guide shaft 309 rotates through the driven bearing 308 and passes through the middle of the filter inner core 302. When the oil passes through the filter and flows into the middle of the filter inner core 302, and then is discharged from the oil outlet 311, the oil will push the guide shaft 309 to rotate along the driven bearing 308. This can rectify the outflowing oil, make the oil flow more uniform, reduce pressure fluctuations, and may also enhance the turbulence of the oil, indirectly improving the stability of the subsequent engine fuel supply.

[0024] Furthermore, the filter screen 312 and the oil outlet 311 are connected by threads. The filter screen 312 is made of ultra-fine glass fiber filter paper. When the oil is discharged from the oil outlet 311, the filter screen 312 can serve as a supplementary filter for the fine filter layer 304, further intercepting fine impurities and ensuring that the oil reaches the high purity standard.

[0025] Working principle: When needed, first install the oil filter frame 301 into the outer tank 1 of the filter, then connect the oil inlet pipe to the oil inlet 2 and the outlet pipe to the oil outlet 311. When oil is injected into the outer tank 1 of the filter from the oil inlet 2, the oil will impact the rotating fan blade 306. After being impacted, the rotating fan blade 306 will rotate along the bearing 305. During the rotation, the rotating fan blade 306 will drive the scraper 307 to rotate along the surface of the coarse filter layer 303 outside the filter core 302, scraping off the deposits on the surface of the coarse filter layer 303. After the oil passes through the coarse filter layer 303 and the filter core 302 for dual-stage filtration, it will undergo fine filtration through the inner wall of the filter core 302 to improve the filtration effect. Then, when the oil is discharged from the oil outlet 311 in the middle of the can cover 310, it will be guided by the flow guide shaft 309. The flow guide shaft 309 will rotate along the driven bearing 308, thereby generating a turbulent effect in the oil and providing supply stability. Finally, after being filtered and replenished by the filter screen 312, it will be discharged from the oil outlet 311, thus completing the usage process of an automotive filter.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
