Description

Technical Field

[0001] This utility model relates to an air filter end cap, specifically an asymmetrical filter end cap. Background Technology

[0002] Air filter end caps typically have multiple locking blocks that connect to multiple locking slots on the positioning seat. These locking blocks are symmetrically designed, allowing the air filter to be installed on the equipment at any angle. However, due to the asymmetrical support structure on some filter models, even if the filter can be installed, the support structure may be in the wrong position. This requires operators to observe and align the filter in real time, which is time-consuming. Incorrect installation can lead to poor sealing and affect the filtration quality of the air filter. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention provides an asymmetrical filter end cap. This invention features asymmetrical locking blocks, which prevents errors in real time. It can only be assembled at one correct angle, eliminating the need for operators to observe and inspect in real time. This makes operation convenient and ensures the sealing performance and reliability of the air filter.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: an asymmetrical filter element end cap, comprising a cap body, wherein two first locking blocks and one second locking block are provided on the outer periphery of the cap body, the angle between the second locking block and one of the first locking blocks is 120°, the angle between the second locking block and the other first locking block is 130°, and the angle between the two first locking blocks is 110°.

[0005] The two first card blocks and the second card block are at the same height and have the same thickness.

[0006] A sealing groove is provided at one end of the cover for installing a sealing ring, and a step is provided on the outer wall of the cover, the step being flush with the upper surfaces of the two first blocks and the second block.

[0007] The other end of the cover is provided with an inner ring wall and an outer ring wall, the inner ring wall and the outer ring wall are coaxial and form a mounting groove, the mounting groove is used to install an air filter element.

[0008] The thickness of the inner ring wall is greater than the thickness of the outer ring wall, the thickness of the inner ring wall is less than the thickness of the cover, and the inner ring surface of the inner ring wall is flush with the inner ring surface of the cover.

[0009] The cover is provided with a connecting piece inside, and a sleeve is provided at the center of the connecting piece. The central hole of the sleeve is coaxial with the through hole of the cover.

[0010] In summary, this utility model achieves the following technical effects: This utility model has three locking blocks on the outer periphery of the end cap, two of which are the same and the included angles between the three locking blocks are different. This can effectively prevent errors. The asymmetrical method ensures that the end cap can only be installed on the positioning seat (not shown) in a specific direction, preventing improper installation and gaps caused by incorrect installation, and avoiding unfiltered air from entering the equipment. This invention is easy to operate and does not require frequent checks to ensure correct assembly. Attached Figure Description

[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0018] Example: Figure 1 This is a top view of an asymmetrical filter element end cap. Figure 2 yes Figure 1 The schematic diagram shows the dimensions of the cover 1, which has two first locking blocks 109 and one second locking block 110 on its outer periphery. The angle between the second locking block 110 and one of the first locking blocks 109 is 120°, the angle between the second locking block 110 and the other first locking block 109 is 130°, and the angle between the two first locking blocks 109 is 110°.

[0019] This utility model has three locking blocks on the outer periphery of the end cap, two of which are identical. The included angles between the three locking blocks are different, which can effectively prevent errors. The asymmetrical method ensures that the end cap can only be installed on the positioning seat (not shown) in a specific direction, preventing improper installation and gaps caused by incorrect installation, and avoiding unfiltered air from entering the equipment.

[0020] The two first locking blocks 109 and the second locking block 110 of this invention are at the same height and have the same thickness. The three locking blocks have the same thickness (axial distance along the end cap) and the same width, which is 20mm in this embodiment. Each locking block is self-symmetrical, with the included angles measured from its own line of symmetry being 110°, 120°, and 130°, forming an asymmetrical structure. This invention designs the angles to be 110°, 120°, and 130°, approximately evenly distributed around the circumference, maintaining balance.

[0021] The outer periphery of the first locking block 109 of this utility model is a first arc shape, and the two sides are first transition surfaces 111. The outer periphery of the second locking block 110 is a second arc shape, and the two sides are second transition surfaces 112. The first arc shape and the second arc shape are the same circle. The angle between the first transition surface 111 and the first arc shape is larger, and the angle between the second transition surface 112 and the second arc shape is smaller, so that the shapes of the first locking block and the second locking block are different, further improving the error prevention effect.

[0022] Figure 3 This is a cross-sectional view of the end cap. One end of the cap body 1 is provided with a sealing groove 101 for installing a sealing ring. The outer wall of the cap body 1 is provided with a step 102, which is flush with the upper surfaces of the two first locking blocks 109 and the second locking block 110.

[0023] The sealing ring is used to improve the sealing performance and prevent unfiltered gas from entering the equipment. Step 102 keeps the three blocks at the same horizontal height, which facilitates processing and installation.

[0024] The other end of the cover 1 is provided with an inner ring wall 103 and an outer ring wall 104. The inner ring wall 103 and the outer ring wall 104 are coaxial and form a mounting groove 105. The mounting groove 105 is used to install an air filter element.

[0025] The thickness of the inner ring wall 103 is greater than the thickness of the outer ring wall 104, the thickness of the inner ring wall 103 is less than the thickness of the cover 1, and the inner ring surface of the inner ring wall 103 is flush with the inner ring surface of the cover 1.

[0026] This invention expands the outer ring wall 104 outwards without affecting the airflow channel inside the end cap or the gas flow rate.

[0027] The cover 1 is provided with a connecting piece 106 inside, and a sleeve 107 is provided at the center of the connecting piece 106. The central hole 108 of the sleeve 107 is coaxial with the through hole of the cover 1.

[0028] The end cap of this utility model is installed on the end of the air filter element through the mounting groove 105 and fixed by the center hole 108 and bolts. Then, the air filter element with the end cap installed is assembled onto the equipment. The different angles of the three clips are used to achieve quick installation, prevent incorrect installation, and avoid gaps.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
