Description

Technical Field

[0001] This utility model relates to the field of air compressor filter technology, and in particular to a filter element for an air compressor filter. Background Technology

[0002] Air compressor filter elements are core components in air compressor units used to purify the intake air. Installed in the air intake passage of the air compressor, they filter out dust, impurities, and moisture contaminants from the air, preventing these substances from entering the air compressor and causing equipment wear, malfunctions, or affecting the quality of compressed air. During the operation of the air compressor, outside air must first pass through the filter element before entering the compression stage. Therefore, the performance of the filter element directly affects the operating efficiency, service life, and cleanliness of the output gas of the air compressor, and is an important component to ensure the stable operation of the air compressor.

[0003] Existing air compressor filter elements are installed inside the filter using bolts or snap-fit ​​connections. The filter material intercepts and filters the air to prevent impurities from entering the air compressor. However, the installation and removal process is cumbersome. Bolts require repeated tightening with tools, and snap-fit ​​connections can loosen over time, leading to misalignment. Furthermore, most existing filter elements have a single filtration structure, lacking a multi-stage filtration design, causing the filter material to clog quickly, affecting filtration efficiency and lifespan. The elements also lack the convenience of combining multiple elements, making it difficult to flexibly add filtration stages when increased efficiency is needed. This results in low flexibility and an inability to meet the filtration requirements of different scenarios. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a filter element for an air compressor filter, which aims to improve the existing technology where it is difficult to conveniently combine multiple filter elements, and when it is necessary to improve filtration efficiency, it is not possible to flexibly increase the number of filtration layers, resulting in low flexibility of use and difficulty in meeting the filtration needs of different scenarios.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filter element for an air compressor filter, comprising two mounting seats, each of the two mounting seats being provided with an installation mechanism, the installation mechanism being used for quick installation and disassembly of the filter element, a fixing ring being fixedly connected to the top of the top mounting seat, and a connecting mechanism being provided on the outer wall of the fixing ring, the connecting mechanism being used for convenient connection of multiple filter elements; Each of the two mounting bases is fixedly connected with a threaded ring, and each of the two threaded rings is threaded with a threaded strip inside. Each of the two threaded strips is fixedly connected with the same inner core inside. An outer core is provided inside the inner core. A protective component is provided on the top inner side of the mounting base, and a clamping component is provided on the bottom inner side of the top mounting base.

[0006] As a further description of the above technical solution: The connecting mechanism includes two springs, which are fixedly connected to the left and right sides of the outer wall of the fixed ring. A retaining plate is fixedly connected to the opposite side of the two springs. A telescopic sleeve is fixedly connected to the adjacent side of the two retaining plates. The telescopic sleeve is fixedly connected to the left and right sides of the outer wall of the fixed ring. Circular holes are opened at the left and right ends of the inner bottom of the bottom mounting base. An extrusion assembly is provided on the left and right sides of the outer wall of the bottom mounting base.

[0007] As a further description of the above technical solution: The protective assembly includes a filter cartridge, the outer wall of which is disposed on the top inner side of the bottom mounting base, and the outer wall of the filter cartridge has multiple filter ports.

[0008] As a further description of the above technical solution: The protective assembly also includes two connecting plates. The tops of the two connecting plates are fixedly connected to the front and rear sides of the bottom of the filter cartridge. The opposite sides of the two connecting plates are fixedly connected to a locking block. The front and rear sides of the bottom mounting base are provided with locking grooves.

[0009] As a further description of the above technical solution: The protective assembly also includes two fixing rods, with the opposite sides of the two fixing rods respectively fixedly connected between adjacent connecting plates.

[0010] As a further description of the above technical solution: The clamping assembly includes a fixing cylinder, the top of which is fixedly connected to the inner bottom of the top mounting base. The bottom of the fixing cylinder is fixedly connected to multiple fixing blocks. Each of the multiple fixing blocks has an engagement groove between adjacent blocks, and each of the multiple engagement grooves has a locking pin engaged inside.

[0011] As a further description of the above technical solution: The extrusion assembly includes two springs, which are fixedly connected to the left and right sides of the outer wall of the bottom mounting base, respectively, and extrusion columns are fixedly connected to the opposite sides of the two springs.

[0012] As a further description of the above technical solution: The mounting base described above has two rotating seats fixedly connected to its front and rear sides, and the same pull ring is rotatably connected inside both rotating seats.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by aligning the threaded strips at both ends of the inner core with the threaded ring of the mounting base, rotating the inner core to engage the threaded strips with the threaded ring and screw them in, the inner core and the mounting base are fixed, and the outer core is installed simultaneously. During installation, the clamping component contacts the external column to clamp and prevent movement. During filtration, the gas is initially filtered by the protective component and then enters the space between the inner core and the outer core for further filtration. During disassembly, the inner core is rotated in the opposite direction to disengage the threaded strips, thus realizing the rapid installation and disassembly of the filter element. The installation position is precise and stable, and the gas is filtered in stages to improve the filtration effect.

In this utility model, by aligning the fixing ring at the top of one filter element with the inner side of the mounting base at the bottom of another filter element and pushing it, the clamping plate is squeezed and moves, squeezing the first spring. The telescopic sleeve retracts synchronously. When the clamping plate is aligned with the round hole, the first spring resets and pushes the clamping plate into the round hole for fixation. When disassembling, the squeezing component squeezes the clamping plate out of the round hole, pulling the filter element apart. The telescopic sleeve retracts or extends with the deformation of the spring, realizing the rapid connection and disassembly of multiple filter elements. After connection, it is stable and reliable. The directional movement of the clamping plate ensures accurate docking. The squeezing component can easily disconnect the connection, improving the flexibility and efficiency of filter element connection and meeting the needs of combined use in multiple scenarios.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Reference Figure 1 , Figure 3 and Figure 5 An embodiment of this utility model provides: a filter element for an air compressor filter, including two mounting seats 1, and a mounting mechanism 2 is provided between adjacent mounting seats 1. The mounting mechanism 2 is used for quick installation and removal of the filter element. A fixing ring 3 is fixedly connected to the top of the top mounting seat 1. A connecting mechanism 4 is provided on the outer wall of the fixing ring 3. The connecting mechanism 4 is used to facilitate the connection of multiple filter elements. Two adjacent mounting bases 1 are fixedly connected with threaded rings 21, and threaded strips 22 are threadedly connected inside the two threaded rings 21. The same inner core 23 is fixedly connected between adjacent inner cores of the two threaded strips 22. An outer core 24 is provided inside the inner core 23. A protective component 25 is provided on the top inner side of the mounting base 1, and a clamping component 26 is provided on the bottom inner side of the top mounting base 1. Specifically, when installing the filter element, align the threaded strips 22 at both ends of the inner core 23 with the threaded rings 21 on the two mounting seats 1 respectively, rotate the inner core 23 to make the threaded strips 22 engage with the threaded rings 21, and rotate the threaded strips 22 along the inside of the threaded rings 21, driving the inner core 23 to move towards the mounting seat 1 until the threaded strips 22 are completely screwed into the threaded rings 21. Through the cooperation between the threaded rings 21 and the threaded strips 22, the inner core 23 is fixedly connected to the mounting seat 1. At the same time, the outer core 24 inside the inner core 23 is installed in place synchronously with the inner core 23. During installation, the clamping component 26 on the bottom inner side of the top mounting base 1 contacts the external column, clamping the column and preventing the filter element from moving during installation, thus ensuring accurate installation. During filtration, the gas first flows through the protective component 25 on the top inner side of the mounting base 1, where it performs preliminary filtration of impurities. The filtered gas then enters between the inner core 23 and the outer core 24, and is discharged after further filtration by the inner core 23 and the outer core 24. Through the cooperation of the protective component 25 with the inner core 23 and the outer core 24, the impurities are filtered in stages. When the filter element needs to be disassembled, rotate the inner core 23 in the opposite direction. The threaded bar 22 rotates in the opposite direction along the threaded ring 21 and disengages. The inner core 23 and the outer core 24 are removed from the mounting base 1 along with the threaded bar 22, thus completing the disassembly. When connecting multiple filter elements, the connecting mechanism 4 of one filter element is connected to the corresponding structure of another filter element through the connecting mechanism 4 on the outer wall of the fixing ring 3 on the top mounting base 1, so as to realize the combined installation of multiple filter elements. The use of threaded ring 21 and threaded strip 22 enables quick installation and removal of filter elements; the use of protective component 25 enables preliminary filtration of impurities; the use of clamping component 26 ensures stable filter element position during installation; and the use of fixing ring 3 and connecting mechanism 4 enables convenient connection of multiple filter elements, improving filter element installation efficiency and filtration effect.

[0019] Reference Figure 2 and Figure 4 The connecting mechanism 4 includes two springs 41, which are fixedly connected to each other on the left and right sides of the outer wall of the fixed ring 3. The two springs 41 are fixedly connected to each other on the opposite side. The two springs 42 are fixedly connected to each other on the adjacent side. The two telescopic sleeves 43 are fixedly connected to each other on the left and right sides of the outer wall of the fixed ring 3. The bottom bottom of the inner side of the bottom mounting base 1 is provided with round holes 44 at both the left and right ends. The bottom wall of the bottom mounting base 1 is provided with extrusion components 45 on both the left and right sides. Specifically, when connecting multiple filter elements, align the fixing ring 3 at the top of one filter element with the inner side of the bottom mounting base 1 of another filter element, push the two filter elements closer to each other, and the clamping plate 42 contacts and is pressed against the inner wall of the bottom mounting base 1. The clamping plate 42 moves in the adjacent direction, compressing the spring 41 to deform it. The telescopic sleeve 43 retracts synchronously with the clamping plate 42. When the clamping plate 42 is aligned with the round hole 44, the spring 41 returns to its original shape, pushing the clamping plate 42 into the round hole 44. Through the cooperation between the clamping plate 42 and the round hole 44, the two filter elements are fixedly connected. The telescopic sleeve 43 extends as the spring 41 returns to its original position. Through the cooperation of the telescopic sleeve 43 and the spring 41, the movement direction of the clamping plate 42 is restricted, ensuring that the clamping plate 42 is accurately embedded in the round hole 44. When the filter element needs to be separated, the pressing component 45 on the outer wall of the bottom mounting base 1 is operated to press the clamping plate 42 inward. The clamping plate 42 moves in the adjacent direction and presses the spring 41. The spring 41 deforms, the telescopic sleeve 43 retracts, and the clamping plate 42 disengages from the round hole 44. At this time, the two filter elements are pulled away from each other, so that the fixing ring 3 disengages from the inside of the bottom mounting base 1, thus completing the separation of the filter element. When installing the filter element, the threaded bar 22 and the threaded ring 21 engage to fix the inner core 23. The clamping assembly 26 clamps the outer post to prevent movement. During filtration, the gas is initially filtered by the protective assembly 25 and then enters the space between the inner core 23 and the outer core 24 for further filtration. When removing the filter element, rotate the inner core 23 in the opposite direction to disengage the threaded bar 22 from the threaded ring 21 to remove it. The quick connection and disassembly of the filter element is achieved through the cooperation of spring 41 and clamping plate 42; the directional movement of clamping plate 42 is ensured through the cooperation of telescopic sleeve 43 and clamping plate 42; and the connection is conveniently released through the cooperation of squeezing component 45 and clamping plate 42. This enables the connection mechanism 4 to efficiently complete the combination, installation and disassembly of multiple filter elements, thus improving the flexibility of filter element connection.

[0020] Reference Figure 5 The protective component 25 includes a filter cartridge 251. The outer wall of the filter cartridge 251 is located on the inner top of the bottom mounting base 1. The outer wall of the filter cartridge 251 has multiple filter ports 252. The protective component 25 also includes two connecting plates 253. The tops of the two connecting plates 253 are fixedly connected to the front and rear sides of the bottom of the filter cartridge 251. The opposite sides of the two connecting plates 253 are fixedly connected to a locking block 254. The front and rear sides of the bottom mounting base 1 are provided with locking grooves 255. The protective component 25 also includes two fixing rods 256. The opposite sides of the two fixing rods 256 are respectively fixedly connected between the adjacent sides of the two connecting plates 253. Specifically, when installing the protective component 25, the filter cartridge 251 is aligned with the inner top of the bottom mounting base 1, so that the locking block 254 on the connecting plate 253 corresponds to the locking groove 255 of the bottom mounting base 1. The filter cartridge 251 is pushed downward, and the connecting plate 253 moves downward synchronously with the filter cartridge 251. The locking block 254 contacts and is squeezed against the inner wall of the bottom mounting base 1, and the connecting plate 253 deforms slightly in the adjacent direction. When the locking block 254 is aligned with the locking groove 255, the connecting plate 253 returns to its original shape, causing the locking block 254 to be embedded in the locking groove 255. Through the cooperation of the locking block 254 and the locking groove 255, the filter cartridge 251 is fixed inside the bottom mounting base 1. The fixing rod 256 between the two connecting plates 253 is in an extended state. The cooperation between the fixing rod 256 and the connecting plate 253 enhances the structural stability of the two connecting plates 253 and prevents the connecting plate 253 from being excessively deformed, causing the locking block 254 to disengage from the slot 255. During the filtration process, the gas first enters the interior of the filter cartridge 251 and flows out through the filter port 252 on the outer wall of the filter cartridge 251. The filter port 252 intercepts larger impurities in the gas to achieve preliminary filtration. The gas after preliminary filtration continues to flow between the inner core 23 and the outer core 24 for further filtration. The cooperation between the filter cartridge 251 and the filter port 252 reduces the impurity load on subsequent filtration components. When disassembling the protective component 25, press the connecting plate 253 in the adjacent direction to disengage the locking block 254 from the locking groove 255, pull the filter cartridge 251 upward, and move the connecting plate 253 and the fixing rod 256 out of the bottom mounting base 1 simultaneously to complete the disassembly of the protective component 25. The cooperation between the locking block 254 and the locking slot 255 enables the secure installation and removal of the protective component 25; the cooperation between the filter cartridge 251 and the filter port 252 enables the initial filtration of impurities; and the cooperation between the fixing rod 256 and the connecting plate 253 enhances structural stability and improves the filtration efficiency and maintenance convenience of the filter element.

[0021] Reference Figure 1 , Figure 4 and Figure 5 The clamping assembly 26 includes a fixed cylinder 261, the top of which is fixedly connected to the bottom inner side of the top mounting base 1. The bottom of the fixed cylinder 261 is fixedly connected to a plurality of fixed blocks 262. Each of the plurality of fixed blocks 262 has a locking groove 263 between adjacent blocks. Each of the locking grooves 263 has a locking post 264 inside. The extrusion assembly 45 includes two springs 451, which are fixedly connected to the left and right sides of the outer wall of the bottom mounting base 1 respectively. Each of the two springs 451 has an extrusion post 452 fixedly connected to the side of the two springs 451 that is far apart from each other. The top front and rear sides of the top of the top mounting base 1 are fixedly connected to two rotating seats 5. Each of the two rotating seats 5 has the same pull ring 6 rotatably connected inside. Specifically, when installing the filter element, the external post is inserted into the bottom of the fixing cylinder 261, the clamping post 264 contacts the surface of the post and is embedded in the locking groove 263. Through the cooperation between the clamping post 264 and the locking groove 263, the connection stability between the post and the fixing block 262 is enhanced. The clamping assembly 26 clamps the post to prevent the filter element from moving during the installation process and ensures accurate installation position. When disassembling the connected filter element, press the squeezing column 452 in the adjacent direction. The squeezing column 452 squeezes the second spring 451 to deform it. The squeezing column 452 pushes the clamping plate 42 to move in the adjacent direction. The clamping plate 42 squeezes the first spring 41 and disengages from the round hole 44. Through the cooperation of the squeezing column 452 and the second spring 451, the clamping plate 42 and the round hole 44 are quickly separated, and the filter element is released from fixation. When moving the filter element, rotate the pull ring 6 to rotate it around the rotating seat 5 to a suitable angle. Pull the pull ring 6 to drive the top mounting seat 1 and the entire filter element to move. Through the cooperation of the rotating seat 5 and the pull ring 6, the filter element can be easily transported without direct contact with the filter element body. During filtration, the gas is initially filtered through the filter port 252 of the filter cartridge 251, and then enters the space between the inner core 23 and the outer core 24 for further filtration. When disassembling the protective component 25, press the connecting plate 253 to disengage the locking block 254 from the locking groove 255, and pull the filter cartridge 251 to remove it. The engagement of the locking post 264 and the locking groove 263 ensures stable clamping during installation; the engagement of the squeezing post 452 and the spring 451 enables quick release of the filter element connection; and the engagement of the rotating seat 5 and the pull ring 6 facilitates convenient movement of the filter element, thus improving the installation stability, disassembly efficiency, and ease of movement of the filter element.

[0022] Working principle: When installing the protective component 25, align the filter cartridge 251 with the inner top of the bottom mounting base 1, so that the locking block 254 on the connecting plate 253 corresponds to the locking groove 255 of the bottom mounting base 1. Push the filter cartridge 251 downward, and the connecting plate 253 moves downward synchronously with the filter cartridge 251. The locking block 254 contacts and is squeezed against the inner wall of the bottom mounting base 1. The connecting plate 253 deforms slightly in the adjacent direction. When the locking block 254 is aligned with the locking groove 255, the connecting plate 253 returns to its original shape, causing the locking block 254 to be embedded in the locking groove 255. The filter cartridge 251 is fixed by the cooperation between the locking block 254 and the locking groove 255. At this time, the fixing rod 256 between the two connecting plates 253 is in the extended state. The cooperation between the fixing rod 256 and the connecting plate 253 enhances the structural stability and prevents the locking block 254 from falling out of the locking groove 255. When installing the inner core 23 and the outer core 24, align the threaded strips 22 at both ends of the inner core 23 with the threaded rings 21 on the two mounting seats 1 respectively. Rotate the inner core 23 to make the threaded strips 22 engage with the threaded rings 21. The threaded strips 22 rotate along the inside of the threaded rings 21, driving the inner core 23 to move towards the mounting seat 1 until the threaded strips 22 are completely screwed into the threaded rings 21. The inner core 23 and the mounting seat 1 are fixedly connected through the cooperation of the threaded rings 21 and the threaded strips 22. The outer core 24 inside the inner core 23 is installed in place synchronously with the inner core 23. During the installation process, the outer post is inserted into the bottom of the fixing cylinder 261 at the bottom of the inner side of the top mounting seat 1. The locking post 264 contacts the surface of the post and is embedded in the locking groove 263. Through the cooperation of the locking post 264 and the locking groove 263, the clamping assembly 26 clamps the post to prevent the filter element from moving during installation and ensure accurate installation position. During filtration, the gas first enters the interior of the filter cartridge 251 and flows out through the filter port 252 on the outer wall of the filter cartridge 251. The filter port 252 intercepts larger impurities in the gas, achieving preliminary filtration. The gas after preliminary filtration continues to flow between the inner core 23 and the outer core 24, and is discharged after further filtration by the inner core 23 and the outer core 24. Through the cooperation of the protective component 25 with the inner core 23 and the outer core 24, the impurities are filtered in stages, reducing the impurity load on subsequent filtration components. When connecting multiple filter elements, align the fixing ring 3 at the top of one filter element with the inner side of the bottom mounting base 1 of another filter element, push the two filter elements closer to each other, and the clamping plate 42 contacts and is pressed against the inner wall of the bottom mounting base 1. The clamping plate 42 moves in the adjacent direction, compressing the spring 41 to deform it. The telescopic sleeve 43 retracts synchronously with the clamping plate 42. When the clamping plate 42 is aligned with the round hole 44, the spring 41 returns to its original shape, pushing the clamping plate 42 into the round hole 44. The two filter elements are fixedly connected through the cooperation between the clamping plate 42 and the round hole 44. At the same time, the telescopic sleeve 43 extends as the spring 41 returns to its original position. The cooperation between the telescopic sleeve 43 and the spring 41 restricts the movement direction of the clamping plate 42, ensuring that the clamping plate 42 is accurately embedded in the round hole 44. When moving the filter element, rotate the pull ring 6 on the front and rear sides of the top mounting base 1 to rotate it around the rotating base 5 to a suitable angle, and pull the pull ring 6 to move the top mounting base 1 and the entire filter element. The filter element can be easily moved by the cooperation between the rotating base 5 and the pull ring 6 without direct contact with the filter element body. When the filter elements need to be separated, press the squeezing post 452 on the outer wall of the bottom mounting base 1 in the adjacent direction. The squeezing post 452 squeezes the second spring 451 to deform it. The squeezing post 452 pushes the clamping plate 42 to move in the adjacent direction. The clamping plate 42 squeezes the first spring 41 and disengages from the round hole 44. The clamping plate 42 and the round hole 44 are quickly separated by the cooperation of the squeezing post 452 and the second spring 451, and the fixing between the filter elements is released. At this time, pull the two filter elements away from each other, so that the fixing ring 3 disengages from the inside of the bottom mounting base 1, and the filter elements are separated. When disassembling the protective component 25, press the connecting plate 253 in the adjacent direction to disengage the locking block 254 from the locking groove 255. Pull the filter cartridge 251 upward to move the connecting plate 253 and the fixing rod 256 out of the bottom mounting base 1 simultaneously. When disassembling the inner core 23 and the outer core 24, rotate the inner core 23 in the opposite direction. The threaded bar 22 rotates in the opposite direction along the threaded ring 21 and disengages. The inner core 23 and the outer core 24 are removed from the mounting base 1 along with the threaded bar 22.
