The traditional air compressor intake filter and silencer adopts a single-layer filtration, which has a poor filtering effect and is inconvenient to disassemble and maintain. Therefore, an air compressor intake filter and silencer is proposed. Utility Model Content

[0028] See also Figures 1 to 4 In this embodiment, an air compressor intake filtering and silencing device includes a connecting seat 1, a filtering assembly 2 arranged on the side of the connecting seat 1, and a guide assembly 3 movably connected to the inside of the filtering assembly 2.

[0029] The filter assembly 2 is provided to filter the intake air, and the flow guide assembly 3 cooperates with the filter assembly 2 to guide the airflow entering the interior, thereby achieving noise reduction and performing secondary filtration to improve the intake air quality.

[0030] In this embodiment, the filter assembly 2 includes an air intake cover 21 movably connected to the side of the connecting seat 1, a sealing seat 22 movably connected to the side of the air intake cover 21, a paper filter cartridge 23 movably connected to the side of the sealing seat 22, and a support frame 24 slidably connected to the inside of the paper filter cartridge 23.

[0031] An air inlet cover 21 is provided to connect and fix the connecting seat 1 and the sealing seat 22 , the paper filter cartridge 23 performs primary filtering, and the support frame 24 supports the interior of the paper filter cartridge 23 .

[0032] In this embodiment, a threaded tube 25 is fixedly installed on the side of the connecting seat 1, and a through-connecting tube cavity is opened inside the threaded tube 25 and the connecting seat 1. A threaded groove 26 is provided on the outer side of the connecting seat 1, and one end of the air inlet hood 21 is embedded in the threaded groove 26 and fixed to the connecting seat 1 by threads.

[0033] A threaded tube 25 with a tubular cavity is fixedly installed with the connecting seat 1, so that the threaded tube 25 can be connected to the air compressor to fix the device. At the same time, the threaded tube 25 cooperates with the connecting seat 1 to provide air intake for the air compressor. A threaded groove 26 is set on the outside of the connecting seat 1 to fix the air intake cover 21 on the outside of the connecting seat 1.

[0034] In this embodiment, a plurality of evenly distributed air inlet holes are opened on the surface of the air inlet hood 21, and a threaded pattern is provided on the inner wall of the end of the air inlet hood 21 away from the connecting seat 1. The side of the sealing seat 22 is embedded in the interior of the air inlet hood 21 and is fixed to the air inlet hood 21 by threads.

[0035] An air intake hole is provided on the surface of the air intake cover 21 to provide an air intake hole position, and a threaded pattern is provided inside the air intake cover 21 to cooperate with the sealing seat 22 for threaded connection and fixation. In this way, the connecting seat 1 and the sealing seat 22 are connected and fixed through the air intake cover 21, and the three constitute the outer shell of the filtering and silencer device.

[0036] In this embodiment, the sealing seat 22 is a multi-layer structure, and the side surface of the sealing seat 22 is embedded in the interior of the paper filter cartridge 23 and is rotatably connected to the inner wall of the paper filter cartridge 23 through threads.

[0037] A sealing seat 22 with a multi-layer trapezoidal structure is provided, so that the paper filter cartridge 23 can be nested on the side of the sealing seat 22 and then fixed by threads, and then cooperated with the support frame 24 to ensure the stability of the paper filter cartridge 23 inside the device.

[0038] In this embodiment, the support frame 24 is transversely embedded in the paper filter cartridge 23 and is slidably connected to the inner wall of the paper filter cartridge 23 , and the side surface of the support frame 24 is slidably connected to the side surface of the connecting seat 1 .

[0039] A support frame 24 is arranged to be inserted into the interior of the paper filter cartridge 23 to support the paper filter cartridge 23 and enhance the structural stability of the paper filter cartridge 23. Meanwhile, the side surface of the support frame 24 is slidably connected to the connecting seat 1, so that the two ends of the support frame 24 and the paper filter cartridge 23 are in contact with the connecting seat 1 and the sealing seat 22 respectively, thereby preventing the support frame 24 and the paper filter cartridge 23 from moving inside the device.

[0040] In this embodiment, the flow guide assembly 3 includes a spiral cylinder 31 movably connected to the side of the sealing seat 22 , a plurality of racks 32 fixedly installed on the side of the sealing seat 22 , and a chemical fiber filter cylinder 33 movably connected to the outside of the racks 32 .

[0041] The spiral cylinder 31 is provided to guide the gas entering the interior to form an airflow, and the support rod 32 supports and limits the chemical fiber filter cylinder 33 .

[0042] In this embodiment, the side surface of the sealing seat 22 is rotatably connected to the rotating seat 34 , and the side surface of the rotating seat 34 and the side surface of the spiral cylinder 31 are fixedly installed.

[0043] A rotating seat 34 is arranged on the side of the sealing seat 22, so that the spiral cylinder 31 will rotate under the influence of the airflow when taking in air, and guide the airflow to a certain extent before sending it to the chemical fiber filter cartridge 33, thereby preventing the gas from passing through the fixed position of the chemical fiber filter cartridge 33 and improving the utilization rate of the chemical fiber filter cartridge 33.

[0044] It should be noted that a spiral groove is formed on the surface of the spiral cylinder 31 .

[0045] In this embodiment, the support rods 32 are evenly arranged in a ring shape on the side of the sealing seat 22, the chemical fiber filter cartridge 33 is a ring structure wrapped around the outside of the support rods 32, and the side of the chemical fiber filter cartridge 33 is embedded in the tube cavity of the connecting seat 1.

[0046] Evenly spaced racks 32 are arranged on the side of the sealing seat 22 to support and fix the chemical fiber filter cartridge 33, so as to facilitate the later replacement of the chemical fiber filter cartridge 33 while ensuring the filtering effect of the chemical fiber filter cartridge 33. One end of the chemical fiber filter cartridge 33 is embedded in the tube cavity of the connecting seat 1 so that all incoming air must be filtered by the chemical fiber filter cartridge 33 before entering the tube cavity of the connecting seat 1.

[0047] It should be noted that the lumen opening on the side of the connecting seat 1 is conical, and the chemical fiber filter cartridge 33 is against the inner wall of the conical opening so that the space inside the device and the lumen space are separated by the chemical fiber filter cartridge 33 .

[0048] The working principle of the above embodiment is:

[0049] By rotating the air intake hood 21, the air intake hood 21 is unscrewed from the threaded groove 26 on the side of the connecting seat 1, and the air intake hood 21 is pressed while rotating the sealing seat 22, so that the air intake hood 21 can be removed from the outside of the sealing seat 22, and the paper filter cartridge 23 and the support frame 24 can be rotated. In this way, the paper filter cartridge 23 and the support frame 24 can be removed from the side of the sealing seat 22, and the support frame 24 can be pulled out from the inside of the paper filter cartridge 23 to replace the paper filter cartridge 23, so that the nested chemical fiber filter cartridge 33 is removed from the outside of the frame rod 32, thereby solving the problem of inconvenient later maintenance of the air compressor air intake filter and silencer device.

[0050] In addition, by using the threaded barrel 25 to connect the device to the air inlet of the air compressor, when the air compressor inhales air, the pressure inside the device decreases, and the external gas reaches the paper filter cartridge 23 through the air inlet hole on the surface of the air inlet hood 21, and passes through the support frame 24 to the surface of the spiral barrel 31 after the initial filtration of the paper filter cartridge 23. While the airflow passes through the spiral groove on the surface of the spiral barrel 31 to drive the spiral barrel 31 to rotate, it passes through the spiral barrel 31 to reach the surface of the chemical fiber filter cartridge 33, and after being filtered by the chemical fiber filter cartridge 33, it enters the tube cavity of the connecting seat 1, and reaches the air compressor through the tube cavity inside the threaded barrel 25. The double filtration of the air by the paper filter cartridge 23 and the chemical fiber filter cartridge 33 reduces the possibility of impurities entering the air compressor, improves the air intake quality, and thus solves the problem of poor filtering effect of the traditional air compressor intake filter and silencer.

[0051] Compared with the prior art, the utility model provides an air compressor intake filter silencer, which has the following beneficial effects:

[0052] 1. The air intake filter and silencer device for the air compressor can rotate the air intake cover to unscrew it from the threaded groove on the side of the connecting seat, and rotate the sealing seat while pressing the air intake cover to remove the air intake cover from the outside of the sealing seat, and rotate the paper filter cartridge and the support frame, so that the paper filter cartridge and the support frame can be removed from the side of the sealing seat, and the support frame can be pulled out from the inside of the paper filter cartridge to replace the paper filter cartridge, so that the nested chemical fiber filter cartridge can be removed from the outside of the frame rod, thereby solving the problem of inconvenient later maintenance of the air intake filter and silencer device for the air compressor.

[0053] 2. The air compressor intake filter and silencer device connects the device to the air inlet of the air compressor by using a threaded barrel. When the air compressor inhales air, the pressure inside the device decreases, and the external gas reaches the paper filter cartridge through the air inlet hole on the surface of the intake hood, passes through the support frame to the surface of the spiral barrel after the initial filtration of the paper filter cartridge, and while the airflow passes through the spiral groove on the surface of the spiral barrel to drive the spiral barrel to rotate, it passes through the spiral barrel to the surface of the chemical fiber filter cartridge, enters the tube cavity of the connecting seat after being filtered by the chemical fiber filter cartridge, and reaches the air compressor through the tube cavity inside the threaded barrel.
