Description

Technical Field

[0001] This invention relates to the field of air filter technology, and more specifically to a cleaning filter. Background Technology

[0002] Cable connectors are mainly used in communication equipment for transmitting data, audio, and video. Cleaning cable connectors is an important step in maintaining cable connection performance and extending service life. For cleaning the inside of cable connectors, an air compressor is usually used to blow air to clean the inside.

[0003] A Chinese patent with publication number CN222056777U discloses a self-sealing air filter, including a filter body and a sealing mechanism. The filter body has an air inlet and an air outlet at both ends. The sealing mechanism includes a sphere, a first sealing ring, a limiting plate, a fixing plate, and a first spring. The first sealing ring is fixedly connected to the outer wall of the sphere; the limiting plate is fixedly connected to the sphere; the fixing plate is fixedly connected to the inner wall of the filter body; and the first spring is fixedly connected between the fixing plate and the limiting plate. By setting up the sealing mechanism, when the filter body is disassembled or replaced, the filter body does not operate, preventing high-speed flowing gas from entering through the air inlet. The first spring, through the limiting plate, moves the sphere towards the air inlet, blocking the air inlet. The first sealing ring prevents gas from flowing out from the gap between the sphere and the air inlet, resulting in good sealing and preventing pollution of the surrounding environment.

[0004] Based on the above search results combined with existing technologies;

[0005] The aforementioned patent can perform simple air filtration through its filter element, but it cannot achieve high-quality filtration. Furthermore, the air blown out of the air compressor may contain impurities such as water, oil, iron slag, rust, and sand, which cannot be effectively filtered out, thus presenting certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a cleaning filter that, through a multi-stage filtration device, effectively filters the air blown out by the air compressor, thereby improving the cleaning effect on cable connectors.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a cleaning filter, including a filter housing, both ends of the filter housing are fixedly installed with plugs, the plugs and the filter housing are connected by a plurality of fixing bolts through threads, O-rings are fixedly installed at both ends inside the filter housing, a plurality of sealing gaskets are fixedly installed inside the filter housing, an air inlet and an air outlet are respectively opened on one side of the two plugs, and a filter assembly and a snap-fit ​​assembly are also included.

[0008] The filter assembly includes a sodium hydroxide filter box, a pair of filter boxes one, a pair of activated carbon filter boxes, and multiple filter boxes two, all fixedly installed between two adjacent sealing gaskets inside the filter housing.

[0009] The snap-fit ​​assembly includes a retaining ring that is fixedly installed on one side of the plug.

[0010] In some embodiments, a filter box cover is fixedly installed on one side of each of the filter boxes 1, 2, activated carbon filter box and sodium hydroxide filter box, and each filter box cover is connected to the filter box 1, 2, activated carbon filter box and sodium hydroxide filter box by a fixing bolt 2 via thread.

[0011] In some embodiments, a pair of fine iron mesh and a coarse iron mesh are fixedly installed inside each of the first filter boxes, and a pair of meltblown fabrics are fixedly installed inside the second filter box, the sodium hydroxide filter box, and the pair of activated carbon filter boxes. Stainless steel meshes are fixedly installed inside the sodium hydroxide filter box and the pair of activated carbon filter boxes on the opposite side of the pair of meltblown fabrics.

[0012] In some embodiments, the interior of the second filter box, the activated carbon filter box, and the sodium hydroxide filter box is filled with PP cotton, an activated carbon layer, and a sodium hydroxide layer, respectively.

[0013] In some embodiments, a rotating disk is rotatably mounted on one side of the fixed ring, a support ring is fixedly mounted on one end of the plug, a plurality of threaded rods are rotatably passed through the support ring at equal intervals, an active conical toothed ring is fixedly mounted inside the rotating disk, and a driven conical toothed ring is fixedly mounted at the end of each threaded rod, with the active conical toothed ring and the driven conical toothed ring meshing with each other.

[0014] In some embodiments, each threaded rod is threadedly connected to a threaded cylinder, and an arc-shaped clamping block is fixedly installed on one side of the threaded cylinder, with the arc-shaped clamping block slidingly engaging with the plug.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, this utility model achieves multi-layer filtration of the air blown out by the air compressor through the setting of an iron mesh filter layer, an activated carbon layer, a sodium hydroxide layer, and a PP cotton layer. It can effectively filter and intercept impurities such as water, oil, iron slag, rust, and sand in the air. In addition, the filter housing, filter box one, and other filter boxes are all made of transparent organic glass, which makes it easy to see the internal condition of the filter directly. This avoids the inconvenience caused by the inability to see the internal condition of the iron filter used in the past.

[0017] Secondly, this utility model has snap-fit ​​components on both sides of the plug. The rotating disc drives the active bevel gear to rotate, and through the gear transmission relationship, it drives the driven bevel gear and the threaded rod to rotate, which in turn moves the threaded cylinder and the arc-shaped clamping block. This allows the filter to be snapped and fixed to the air compressor's outlet pipe, improving the stability of the device connection.

[0018] This technology solves the problem that existing technologies can perform simple air filtration through filter elements, but cannot achieve high-quality filtration. Furthermore, the air blown out of the air compressor may contain impurities such as water, oil, iron slag, rust, and sand, which cannot be effectively filtered. Attached Figure Description

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an improved cleaning filter. The technical solution of this utility model is as follows:

[0028] like Figure 1 - Figure 4 As shown, a cleaning filter includes a filter housing 1, with plugs 2 fixedly installed at both ends of the filter housing 1. The plugs 2 and the filter housing 1 are connected by multiple fixing bolts 3 via threads. O-rings 6 are fixedly installed at both ends inside the filter housing 1, and multiple sealing gaskets 7 are fixedly installed inside the filter housing 1. An air inlet 5 and an air outlet 8 are respectively opened on one side of the two plugs 2. The filter also includes a filter assembly and a snap-fit ​​assembly. The O-rings 6 can improve the stability of the installation of the internal filter components, and the sealing gaskets 7 can greatly improve the airtightness of the filter, thereby improving the overall filtration effect of the filter.

[0029] The filter assembly includes a sodium hydroxide filter box 28, a pair of filter boxes 16, a pair of activated carbon filter boxes 27, and multiple filter boxes 21, all fixedly installed between two adjacent sealing gaskets 7 inside the filter housing 1. By using the multiple sodium hydroxide filter boxes 28, filter boxes 16, activated carbon filter boxes 27, and filter boxes 21, multi-stage filtration of the air blown out by the air compressor can be achieved, greatly improving the filtration effect of the filter and thus improving the cleaning effect on the cable connectors.

[0030] The snap-fit ​​assembly includes a retaining ring 10 fixedly installed on one side of the plug 2. The retaining ring 10 provides support for the installation of the snap-fit ​​assembly, ensuring that the snap-fit ​​assembly can be successfully snapped and fixed.

[0031] Furthermore, a filter box cover 17 is fixedly installed on one side of each filter box 16, filter box 21, activated carbon filter box 27 and sodium hydroxide filter box 28. Each filter box cover 17 is connected to the filter box 16, filter box 21, activated carbon filter box 27 and sodium hydroxide filter box 28 by a fixing bolt 28 through a thread. The filter box cover 17 can make each filter component form an individual unit, which facilitates targeted replacement in the later stage.

[0032] Furthermore, each filter box 16 has a pair of fine iron mesh 19 and coarse iron mesh 20 fixedly installed inside. Filter box 21, sodium hydroxide filter box 28 and a pair of activated carbon filter boxes 27 have a pair of meltblown fabrics 23 fixedly installed inside. Stainless steel mesh 26 is fixedly installed on the opposite side of the pair of meltblown fabrics 23 inside the sodium hydroxide filter box 28 and the pair of activated carbon filter boxes 27. The fine iron mesh 19 and coarse iron mesh 20 can intercept blocky impurities, such as rust, and prevent them from entering the subsequent filter components and affecting the subsequent filtration effect. The meltblown fabric 23 can not only adsorb smaller impurities, but also block the activated carbon filter box 27 and sodium hydroxide filter box 28. The stainless steel mesh 26 can support the meltblown fabric 23.

[0033] Furthermore, the interiors of filter box 21, activated carbon filter box 27, and sodium hydroxide filter box 28 are respectively filled with PP cotton 24, activated carbon layer 22, and sodium hydroxide layer 25. The activated carbon layer 22 can adsorb some oil stains and other organic matter and other harmful impurities. The sodium hydroxide layer 25 uses its moisture-absorbing properties to adsorb moisture in the air and inside the filter, achieving the effect of drying the air. The PP cotton 24 arranged in sequence can effectively adsorb smaller particles in the pipeline as well as particles from the upper activated carbon filter box 27 and sodium hydroxide filter box 28.

[0034] As a further embodiment of this utility model, a rotating disk 4 is rotatably mounted on one side of the fixed ring 10, and a support ring 15 is fixedly mounted on one end of the plug 2. Multiple threaded rods 11 are rotatably passed through the support ring 15 at equal intervals. An active conical toothed ring 9 is fixedly mounted inside the rotating disk 4, and a driven conical toothed ring 12 is fixedly mounted at the end of each threaded rod 11. The active conical toothed ring 9 and the driven conical toothed ring 12 mesh with each other. By rotating 4, the active conical toothed ring 9 can be rotated. Through gear transmission, the driven conical toothed ring 12 is rotated, which in turn rotates the threaded rod 11, facilitating the movement of the snap-fit ​​assembly.

[0035] Furthermore, each threaded rod 11 is connected to a threaded cylinder 13 via a thread. An arc-shaped clamping block 14 is fixedly installed on one side of the threaded cylinder 13. The arc-shaped clamping block 14 slides with the plug 2. By rotating the threaded rod 11, the threaded cylinder 13 is moved along with the threaded connection, which in turn moves the arc-shaped clamping block 14, thus achieving the effect of connecting and fixing with the air pipe of the air compressor, further improving the connection stability between the filter and the air compressor.

[0036] The specific working method is as follows: First, connect the device to the air compressor's outlet pipe. Rotating the rotating disk 4 causes the active conical gear ring 9 to rotate. Utilizing the effect of conical gear transmission, the rotating active conical gear ring 9 causes the driven conical gear ring 12 to rotate, thereby rotating the threaded rod 11. The threaded cylinder 13, connected by a thread, moves under the action of the rotating threaded rod 11, thus moving the arc-shaped clamping block 14 located at its end. This clamps the air compressor's inlet pipe, improving the stability of the connection between the filter and the air compressor. Then, through the internally set multi-layered... The filtration device achieves high-quality air filtration. The fine iron mesh 19 and coarse iron mesh 20 intercept blocky impurities such as rust. The activated carbon layer 22 adsorbs oil, organic matter, and other harmful impurities. The sodium hydroxide layer 25 absorbs moisture from the air and the filter, achieving air drying. The PP cotton 24 effectively adsorbs smaller particles in the pipeline, as well as particles from the upper activated carbon filter box 27 and sodium hydroxide filter box 28, thus achieving highly efficient filtration.

[0037] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Therefore, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
