Description

Technical Field

[0001] The present invention belongs to the technical field of automotive filters, and particularly relates to an automotive filter for preventing impurity accumulation. Background Art

[0002] The function of an automotive filter is to filter impurities, make the engine oil entering the engine cleaner, and prevent impurities from damaging the engine. However, after being used for a period of time, impurities are likely to accumulate on the filter, affecting the filtering effect. The existing treatment method is generally to replace the filter, but the cost is relatively high.

[0003] Currently, the invention patent with the patent number CN201811091796.0 discloses a new type of automotive filter for preventing impurity accumulation, including a cylinder body. An oil inlet and a rotating shaft are provided at the top of the cylinder body. An oil outlet device and a filtering device are arranged inside the cylinder body. An oil outlet is provided at the bottom of the cylinder body. The rotating shaft is connected to the oil outlet device. The oil inlet is located above the oil outlet device, and the filtering device is located below the oil outlet device. The oil outlet device includes a tray and an oil outlet groove arranged on the tray. A bushing is provided at the center of the tray. The bushing is connected with a connecting shaft, and the connecting shaft is connected with the rotating shaft. It uses a rotating oil outlet device, so that the oil can be evenly dispersed into the filtering device. A filter screen is arranged on the oil outlet device, and a magnet is arranged on the filter screen to adsorb metal iron impurities at the same time, making the filtering effect of the filtering device of the automotive filter better. However, after the automotive filter is used for a period of time, the filtered impurities are likely to accumulate together, affecting the normal use of the filter and reducing the service life of the filter.

[0004] Therefore, aiming at the problem of easy impurity accumulation, it is urgent to be solved to improve the use scenario of the automotive filter. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an automotive filter for preventing impurity accumulation, which aims to solve the technical problem that after being used for a period of time in the prior art, the filtered impurities are likely to accumulate together, reducing the service life of the filter.

[0007] (2) Technical Solutions

[0008] To solve the above technical problems, the present invention provides an automobile filter that prevents impurity accumulation. The automobile filter includes a housing, a pressure spring installed at the upper end of the inner bottom of the housing, a bypass valve and a central tube sequentially installed at the upper end of the pressure spring, a filter paper disposed around the outside of the central tube for filtering, and an end cap disposed at the upper end of the central tube; wherein, a top cap is threadedly connected to the upper end of the housing, a sealing groove is formed on the outside of the top cap, a sealing ring is snap-connected in the sealing groove, a circular ring is sleeved outside the filter paper, first magnets are fixedly connected to both the front and rear ends of the circular ring, lifting control components for controlling the vertical movement of the circular ring are fixedly connected to both the front and rear ends of the housing, second magnets magnetically connected to the first magnets are installed inside the lifting control components, second motors are fixedly connected to both the left and right ends of the housing, a knocking rod is fixedly connected to the outside of the output shaft of the second motor, a knocking hammer is fixedly connected to the outside of the knocking rod, an oil outlet is formed at the center point of the top cap, oil inlets are formed at the upper end of the top cap and are annularly and equally spaced about the center point, a through hole vertically aligned with the oil outlet is formed at the upper end of the end cap, a check valve matching the oil inlets is installed inside the end cap, and a brush is fixedly connected to the inside of the circular ring.

[0009] When using the automobile filter of this technical solution, the check valve is opened, oil enters from the oil inlets, passes through the check valve and enters the housing, the oil is filtered by the filter paper, and the filtered oil then flows out from the through hole through the oil outlet after passing through the central tube. Start the lifting control components and the second motors. The second magnets outside the lifting control components move up and down reciprocally, driving the first magnets to move synchronously, and the circular ring moves up and down in the housing. At the same time, the brush inside the circular ring scrapes the impurities on the surface of the filter paper to avoid impurity accumulation. The second motors rotate forward and reverse alternately, driving the knocking rod to move, and the knocking hammer outside the knocking rod knocks the surface of the housing to further avoid impurity accumulation on the surface of the filter paper. When the filter paper can no longer filter completely, the oil goes from the inner bottom of the housing upwards, the pressure spring pushes the bypass valve upwards, and the oil flows out from the central tube without being filtered.

[0010] Further, the lifting control component includes a fixed seat, a ball screw rotatably installed in the fixed seat, a first motor fixed in the fixed seat for driving the ball screw, and a screw pair installed outside the ball screw. The rotary motion of the ball screw is converted into a linear motion through the screw pair, thereby driving the circular ring to perform a linear reciprocating motion to realize the cleaning of the impurities on the surface of the filter paper.

[0011] Further, the central tube is of a hollowed-out design, and the height of the central tube is equal to that of the filter paper to ensure that all the oil flowing out from the central tube is filtered and the cleanliness of the oil is guaranteed.

[0012] Furthermore, the knocking rod is an equilateral L-shaped structure, and the knocking hammer is a semi-circular structure. The material of the knocking hammer is rubber. Using rubber material can reduce the impact force and noise on the surface of the outer shell while ensuring the knocking effect.

[0013] Furthermore, the number of the oil inlets is not less than 4, so that the oil can flow to the filter paper more evenly, ensuring the comprehensiveness of the filter paper's work.

[0014] Furthermore, the bristles are in contact with the filter paper. The inner diameter of the ring is greater than the outer diameter of the filter paper, and the height of the ring is less than the height of the filter paper. By the contact between the bristles and the filter paper, the impurities on the surface of the filter paper are scraped off, playing a role in preventing the accumulation of impurities.

[0015] Furthermore, a limiting sliding groove matching with the first magnet is arranged on the inner side of the outer shell. Through the design of the limiting sliding groove, the stability of the ring moving up and down in the outer shell is improved.

[0016] Furthermore, the diameter of the bypass valve is smaller than the inner diameter of the outer shell, and the second motor is installed at the midpoint of the outer shell to ensure the symmetry of the knocking point of the knocking hammer on the outer shell.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The automotive filter of the present invention uses the lifting control component to control the ring to make reciprocating up and down movements, so that the bristles inside the ring rub against the filter paper, scraping off the impurities on the surface of the filter paper, thereby preventing the accumulation of impurities on the surface of the filter paper. At the same time, the outer shell is knocked by the knocking hammer, so that the impurities on the surface of the filter paper fall off, effectively preventing the filtered impurities from easily accumulating together to cause the blockage of the filter paper, ensuring the normal use of the filter paper, and improving the service life of the filter.

The automobile filter includes an outer shell 1, a pressure spring 2 installed at the upper end of the inner bottom of the outer shell 1, a bypass valve 3 and a central tube 4 sequentially installed at the upper end of the pressure spring 2, a filter paper 5 disposed around the outside of the central tube 4 for filtering, and an end cap 6 provided at the upper end of the central tube 4; a top screw cap 7 is threadedly connected to the upper end of the outer shell 1. A sealing groove 8 is formed on the outside of the top screw cap 7, and a sealing ring 9 is snap-fitted in the sealing groove 8. A ring 10 is sleeved outside the filter paper 5. First magnets 11 are fixedly connected to both the front and rear ends of the ring 10. Lifting control assemblies 12 for controlling the vertical movement of the ring 10 are fixedly connected to both the front and rear ends of the outer shell 1. A second magnet 13 magnetically connected to the first magnet 11 is installed inside the lifting control assembly 12. Second motors 14 are fixedly connected to both the left and right ends of the outer shell 1. A knocking rod 15 is fixedly connected to the outside of the output shaft of the second motor 14, and a knocking hammer 16 is fixedly connected to the outside of the knocking rod 15. An oil outlet 17 is formed at the center point of the top screw cap 7, and oil inlets 18 annularly and equidistantly distributed around the center point are formed at the upper end of the top screw cap 7. A through hole 19 aligned vertically with the oil outlet 17 is formed at the upper end of the end cap 6. A check valve 20 matching the oil inlets 18 is installed inside the end cap 6. Brush hairs 21 are fixedly connected to the inside of the ring 10.

[0026] Among them, the lifting control assembly 12 includes a fixed seat 121, a ball screw 122 rotatably installed in the fixed seat 121, a first motor 123 fixed in the fixed seat 121 for driving the ball screw 122, and a screw pair 124 installed outside the ball screw 122.

[0027] Meanwhile, the central tube 4 is of a hollow design, and the central tube 4 and the filter paper 5 have the same height. The knocking rod 15 is of an equilateral L-shaped structure, the knocking hammer 16 is of a semi-circular structure, and the material of the knocking hammer 16 is rubber. The number of the oil inlets 18 is not less than 4.

[0028] In addition, the bristles 21 are in contact with the filter paper 5. The inner diameter of the ring 10 is greater than the outer diameter of the filter paper 5, and the height of the ring 10 is less than the height of the filter paper 5. A limiting sliding groove 22 matching the first magnet 11 is formed inside the outer shell 1.

[0029] Furthermore, the diameter of the bypass valve 3 is smaller than the inner diameter of the outer shell 1, and the second motor 14 is installed at the midpoint of the outer shell 1.

[0030] The assembly schematic diagram of the lifting control component 12 in the automotive filter is as Figure 3 shown.

The second magnet 13 outside the lifting control component 12 moves up and down reciprocally, driving the first magnet 11 to move synchronously. The ring 10 moves up and down in the outer shell 1. At the same time, the bristles 21 inside the ring 10 scrape the impurities on the surface of the filter paper 5 to avoid impurity accumulation. The second motor 14 rotates forward and reverses alternately, driving the knocking rod 15 to move. The knocking hammer 16 outside the knocking rod 15 knocks the surface of the outer shell 1 to further avoid impurity accumulation on the surface of the filter paper 5. When the filter paper 5 can no longer filter completely, the oil goes from the bottom of the outer shell 1 upwards, and the pressure spring 2 pushes the bypass valve 3 upwards. The oil flows out from the central tube 4 without being filtered.
