Description

Technical Field

[0001] The utility model relates to the technical field of automotive filters, in particular to an automotive air filter with a multi-layer filtering structure. Background Art

[0002] During the operation of the engine, a large amount of air needs to be inhaled. If the air is not filtered, the dust suspended in the air will be inhaled into the cylinder, which will accelerate the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder will cause serious cylinder scoring, which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or the intake pipe to filter out dust and sand particles in the air and ensure that sufficient and clean air enters the cylinder.

[0003] In order to ensure the filtering effect during the use of the existing automotive air filter, the filter screen is usually set to two layers, that is, two groups of filter screens with different filtering performances. Although this method can increase the filtering effect, in the actual use process, since the vehicle needs to be regularly maintained, and during the maintenance process, it is necessary to select whether to replace the filter screen according to the degree of blockage of the filter screen. The filter screen with relatively light blockage is usually cleaned of the impurities on the surface of the filter screen by a dust blower. For the double-layer filter screen, compared with the single-layer filter screen, it needs to be disassembled to clean it comprehensively. Since the filter screen is mostly fixed in the frame by screws, the cleaning process is cumbersome, causing inconvenience to the maintenance personnel and affecting its service performance. Therefore, there is an urgent need for an automotive air filter with a multi-layer filtering structure to solve the above problems. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an automotive air filter with a multi-layer filtering structure.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] An automotive air filter with a multi-layer filtering structure includes a frame. Five sets of elastic components are respectively fixed at the five edges inside the frame. Each elastic component consists of a sleeve with a hollow structure, a partition plate, a resilient plate, symmetrically arranged compression springs, and symmetrically arranged resilient rods. The top of the resilient rod located above is fixed with a first bearing frame, and a first filter screen is installed inside the first bearing frame. The bottom of the resilient rod located below is fixed with a second bearing frame, and a second filter screen is installed inside the second bearing frame. Two groups of limit blocks are symmetrically fixed on both side walls of the first bearing frame and the second bearing frame, and limit cavities are opened at positions corresponding to the limit blocks on the frame.

[0007] Preferably, the sleeve is formed at the five edges inside the frame, and the partition plate is formed in the middle of the sleeve.

[0008] Preferably, the compression spring is welded to the partition plate and the rebound plate, the rebound plate is welded to the rebound rod, and the rebound rod passes through the sleeve.

[0009] Preferably, the first supporting frame and the second supporting frame are connected to the two groups of rebound rods by screws, the first filter is fixed in the first supporting frame by screws, and the second filter is fixed in the second supporting frame by screws.

[0010] Preferably, the filtering performance of the first filter screen and the second filter screen increases sequentially.

[0011] Preferably, the limiting block is connected to the first carrying frame and the second carrying frame via a spring, and the surface of the limiting block is an arc surface.

[0012] Preferably, the limiting cavity is formed on the frame, and the specifications of the limiting cavity match those of the limiting block.

[0013] Beneficial technical effects of the utility model:

[0014] The utility model designs a connecting mechanism consisting of a sleeve, a compression spring, a rebound plate and a rebound rod. During use, the compression spring is in a compressed state. When the filter needs to be cleaned, it only needs to apply pressure to the limit block to separate it from the limit cavity to release the fixation. Then, relying on the rebound force of the compression spring, the filter is automatically pushed out of the frame through the rebound plate and the rebound rod. At this time, the surface of the filter can be fully cleaned. After cleaning, it only needs to apply pressure to the filter to make the limit block in the limit cavity to fix the filter. This method is not only convenient for cleaning the filter, but also simple in operation, and effectively improves the performance of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0021] like Figures 1 - 3 As shown, the automobile air filter with a multiple filtering structure provided in this embodiment includes a frame 1, and five groups of rebound components 6 are respectively fixed at the five edges of the frame 1. The rebound component 6 is composed of a hollow structure sleeve 601, a partition 603, a rebound plate 605, a symmetrically arranged compression spring 604 and a symmetrically arranged rebound rod 602. A first supporting frame 2 is fixed to the top of the rebound rod 602 located at the top, and a first filter screen 3 is installed in the first supporting frame 2. A second supporting frame 7 is fixed to the bottom end of the rebound rod 602 located at the bottom, and a second filter screen 8 is installed in the second supporting frame 7. Two groups of limit blocks 5 are symmetrically fixed on both side walls of the first supporting frame 2 and the second supporting frame 7, and a limit cavity 4 is opened at the position of the frame 1 corresponding to the limit block 5.

[0022] The sleeve 601 is formed at the five edges in the frame 1 , and the partition 603 is formed in the middle of the sleeve 601 , and the partition 603 divides the inside of the sleeve 601 into equal parts.

[0023] The compression spring 604 is welded to the partition 603 and the rebound plate 605, and the rebound plate 605 is welded to the rebound rod 602. The rebound rod 602 passes through the sleeve 601. During use, the compression spring 604 is in a compressed state. When the filter needs to be cleaned, it is only necessary to apply pressure to the limit block 5 to separate it from the limit cavity 4 to release the fixation. Then, the filter is automatically pushed out of the frame 1 through the rebound plate 605 and the rebound rod 602 by relying on the rebound force of the compression spring 604.

[0024] The first supporting frame 2 and the second supporting frame 7 are connected to the two sets of rebound rods 602 by screws, the first filter 3 is fixed in the first supporting frame 2 by screws, and the second filter 8 is fixed in the second supporting frame 7 by screws. The first supporting frame 2 and the second supporting frame 7 can drive the first filter 3 and the second filter 8 to move under the action of the rebound rod 602.

[0025] The filtering performance of the first filter 3 and the second filter 8 increases successively. The first filter 3 and the second filter 8 can be allergic to impurities in the gas. At the same time, a double-layer filtering structure is adopted to ensure the filtering effect of the gas.

[0026] The limiting block 5 is connected to both the first bearing frame 2 and the second bearing frame 7 through springs. The surface of the limiting block 5 is an arc surface, and the limiting block 5 can be automatically compressed during movement.

[0027] The limiting cavity 4 is formed on the frame 1. The specifications of the limiting cavity 4 match those of the limiting block 5. The combination of the limiting block 5 and the limiting cavity 4 can achieve the fixation and release of the first bearing frame 2 and the second bearing frame 7.

[0028] The working principle of this device: First, install the device. During use, the first filter screen 3 and the second filter screen 8 can filter impurities in the gas. At the same time, with a double-layer filtering structure, the filtering effect of the gas can be ensured. The compression spring 604 is in a compressed state. When it is necessary to clean the first filter screen 3 and the second filter screen 8, only need to apply pressure to the limiting block 5 to separate it from the limiting cavity 4 and release the fixation. Then, rely on the resilience of the compression spring 604 to automatically push out the first bearing frame 2 and the second bearing frame 7 from the frame 1 through the resilient plate 605 and the resilient rod 602. At this time, the surfaces of the first filter screen 3 and the second filter screen 8 can be comprehensively cleaned. After the cleaning is completed, only need to apply pressure to the first bearing frame 2 and the second bearing frame 7 to make the limiting block 5 in the limiting cavity 4 to achieve the fixation of the first filter screen 3 and the second filter screen 8. This method is not only convenient for cleaning the filter screen, but also has a simple operation process, effectively improving the service performance of the device.
