[0002] An air compressor is a device that converts the mechanical energy of a prime mover into gas pressure energy, mainly used for compressing air. It can compress air in a free state and remove water, oil and impurities through a separator and a filter, so as to provide clean and odorless compressed air. There are many types of air compressors, which can be divided into positive displacement compressors, reciprocating compressors, centrifugal compressors, etc. according to the working principle.

[0003] A filter element structure is arranged inside the air compressor. The filter element is used to remove water, oil and impurities in the air. After being used for a period of time, a large amount of impurities will affect the filtering efficiency of the filter element, resulting in the air compressor being unable to work efficiently and normally. For some frequently used air compressors, it is impossible to replace the filter element frequently. From the perspective of energy conservation, it is still preferred to clean the filter element. The filter element after cleaning can still meet the efficiency during the normal use of the air compressor and is more environmentally friendly. However, the existing filter element structures generally use bolts or gluing for fixing, making the disassembly of the filter element more cumbersome and unable to quickly complete the installation or disassembly of the filter element, greatly affecting the cleaning efficiency of the inside of the filter element.

[0035] Please refer to Figures 1 - 8 , in the embodiment of the present utility model, an air compressor filter element structure includes a filter screen 1, a base 2 and a top cover 3. One end of the base 2 is connected to the filter screen 1, and the top cover 3 is detachably arranged at the other end of the filter screen 1;

[0036] A connection component is arranged inside the filter screen 1, and the connection component cooperates with the top cover 3 so that the top cover 3 and the filter screen 1 can be quickly installed or disassembled;

[0037] A cleaning component is also arranged inside the filter screen 1. The cleaning component is connected to the connection component, and the cleaning component can scrape the inner wall of the filter screen 1 under the action of the connection component.

[0038] In this solution, the top cover 3 can be quickly fixed to and separated from the filter screen 1 through the connection component, improving the cleaning efficiency of the inside of the filter screen 1. And during the process of installing or disassembling the top cover 3 on the filter screen 1 by using the connection component, the cleaning component will cooperate with the connection component to scrape the inner wall of the filter screen 1 so that the impurities attached to the inner wall of the filter screen 1 can be more easily removed.

[0039] As a further solution of the present utility model, the connection component includes a rotating ring 4 and an annular groove 5 opened on the inner side wall of the filter screen 1. The rotating ring 4 is movably arranged inside the annular groove 5. A circular ring 6 is rotatably arranged at the bottom of the rotating ring 4, and the bottom surface of the top cover 3 abuts against the top surface of the rotating ring 4;

[0040] A spring 7 is arranged inside the filter screen 1. Two ends of the spring 7 are respectively connected to the base 2 and the circular ring 6.

[0041] In this embodiment, due to the existence of the spring 7 and being in a compressed state, the circular ring 6, the rotating ring 4 and the top cover 3 will all have a tendency to move towards the top end of the filter screen 1 under the action of the spring 7;

[0042] Also, because of the existence of the annular groove 5 and the rotating ring 4 being movably arranged inside the annular groove 5, therefore, the annular groove 5 will limit the rotating ring 4 from moving out of the filter screen 1 under the action of the spring 7.

[0043] As a further solution of the present utility model, a spiral groove 8 is provided on the inner side wall of the annular groove 5. A groove 9 is formed on the side wall of the rotating ring 4, and a ball 10 is rollingly fitted inside the groove 9. The ball 10 is also rollingly fitted inside the spiral groove 8.

[0044] In this embodiment, when the top cover 3 is pushed into the filter net 1 by an external force, the rotating ring 4 and the circular ring 6 will move into the filter net 1 together with the top cover 3. Due to the combined action of the groove 9, the spiral groove 8 and the ball 10, the rotating ring 4 will move into the filter net 1 while rotating. During this process, the circular ring 6 will further compress the spring 7 and will not rotate. Similarly, when the external force applied to the top cover 3 is removed, under the elastic force of the spring 7 during restoration, the circular ring 6 will push the rotating ring 4 to move out of the filter net 1 while rotating.

[0045] As a further solution of the present utility model, a T-shaped ring 11 is fixedly provided at the bottom of the rotating ring 4, and a T-shaped ring groove 12 is formed at the top of the circular ring 6. The T-shaped ring 11 is located inside the T-shaped ring groove 12 and is in sliding fit with each other.

[0046] In this embodiment, through the mutual sliding fit of the T-shaped ring 11 and the T-shaped ring groove 12, the rotational fit between the rotating ring 4 and the circular ring 6 is realized.

[0047] As a further solution of the present utility model, a plurality of clamping blocks 13 are fixedly provided on the outer wall of the top cover 3 along its circumferential surface. A plurality of clamping grooves 14 are formed on the inner side wall at the top end of the filter net 1. The plurality of clamping blocks 13 are respectively located inside the plurality of clamping grooves 14 and are in snap fit with each other.

[0048] A plurality of loading and unloading slots 15 through which the plurality of clamping blocks 13 can penetrate and slide are formed at the top of the filter net 1. The plurality of loading and unloading slots 15 are respectively offset and evenly arranged with the plurality of clamping grooves 14.

[0049] In this embodiment, when disassembling, by pushing the top cover 3 into the filter net 1 with an external force, the top cover 3 drives the plurality of clamping blocks 13 to move out of the plurality of clamping grooves 14. At this time, the top cover 3 can be rotated. Then, by driving the plurality of clamping blocks 13 to rotate through the top cover 3, the plurality of clamping blocks 13 are respectively aligned with the plurality of loading and unloading slots 15. Then, by driving the plurality of clamping blocks 13 to penetrate out of the plurality of loading and unloading slots 15 through the top cover 3, the disassembly of the top cover 3 from the inside of the filter net 1 is completed. During installation, repeat the above operations in reverse.

[0050] As a further solution of the present utility model, the cleaning assembly includes a fixing plate 16. One end of the fixing plate 16 is connected to the bottom surface of the rotating ring 4. A soft brush 17 is fixedly provided on the side wall of the fixing plate 16, and the end of the soft brush 17 is in contact with the inner side wall of the filter net 1.

[0051] In this embodiment, since the soft brush 17 is in contact with the inner wall of the filter screen 1, during the process that the rotary ring 4 rotates and moves into or out of the filter screen 1, the fixing plate 16 will rotate and move synchronously with the rotary ring 4, so that the soft brush 17 fixed on the fixing plate 16 scrapes the inner wall of the filter screen 1.

[0052] As a further solution of the present utility model, a fiberglass filter layer 18 is arranged inside the filter screen 1, and the fiberglass filter layer 18 is made by drawing molten glass (this is the prior art).

[0053] In this embodiment, the fiberglass filter layer 18 has excellent heat resistance, high strength, small elongation, excellent corrosion resistance, smooth surface of the glass filter, and easy dust cleaning.
