[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 3The present invention provides an embodiment of the structure of the air filter for the air intake of the compressor, which includes a main body 1. The main body 1 serves as the core frame of the entire structure of the air filter for the air intake of the compressor, and plays a key role in carrying and fixing the various components, ensuring the stable fit of the components and preventing the components from becoming loose or displaced due to external factors. The main body 1 is internally slidably connected to a filter barrel 2, which is a key component for achieving the air filtration function. The air is gradually purified through different levels of filter materials, first intercepting large particles of dust and impurities, then filtering tiny particles and absorbing harmful gases and odors, thereby improving air cleanliness and ensuring that the quality of the air entering the compressor meets the requirements.

[0033] The sliding connection facilitates installation, disassembly, and subsequent maintenance, ensuring that air filtration is carried out continuously and effectively. An air inlet 11 is fixedly connected to the outside of the main body 1. The air inlet 11 plays an important role in guiding external air into the entire air intake filter structure, ensuring that air can be evenly and stably filtered through the filter barrel 2.

[0034] A connecting post 12 is fixedly connected to the outside of the air inlet 11. This connecting post 12 is a key structural component that connects the air inlet 11 to other related components. It establishes a stable connection, ensuring that the connections between the components will not loosen or disconnect during air flow and equipment operation, maintaining the integrity of the entire air inlet channel. A handle 3 is fixedly connected to one side of the filter barrel 2. This handle 3 is convenient for workers to grasp and apply force, making it easy to move the filter barrel 2 by pulling the handle 3 during installation, removal, maintenance, and inspection.

[0035] The side of the connecting column 12 away from the connecting column 2 16 is slidably connected to the outside of the main body 1. The outside of the connecting column 12 is fixedly connected to the fixing block 2 15. The fixing block 2 15 enables a flexible rotational connection between the connecting column 12 and the connecting column 2 16, ensuring accurate force transmission and maintaining the connection state during frequent rotation operations, and facilitating the rapid docking of the air inlet 11. The outside of the fixing block 2 15 is rotatably connected to the connecting column 2 16. The connecting column 2 16 cooperates with the connecting column 12 to complete a tight connection between the two through a specific rotation and engagement method, ensuring the sealing and firmness of the connection between the air inlet 11 and subsequent components, and preventing air leakage from the connection or unstable connection affecting the air intake.

[0036] A slot is provided inside the connecting column 16, and the slot is L-shaped. The L-shaped design of the slot can precisely match the fixing block 15. When the fixing block 15 is rotated to a specific angle and snaps into the slot, it achieves precise positioning and a secure locking effect, so that the connection between the air inlet 11 and related components remains stable even when affected by external factors, preventing accidental disengagement and ensuring the continuity and stability of the air intake process. A limiting ring 17 is fixedly connected to the inside of the connecting column 16. The limiting ring 17 has the dual functions of limiting and assisting the sealing ring 18. On the one hand, it limits the range of movement of the sealing ring 18, so that it is accurately positioned at the critical sealing position. On the other hand, it fits tightly with the sealing ring 18, enhancing the overall sealing of the connection, preventing the filtered air from leaking out, and ensuring that the air flows to the compressor according to the predetermined filtering path.

[0037] A sealing ring 18 is slidably connected to one side of the limiting ring 17. Driven by the elastic force of spring 2 14 and the limiting action of limiting ring 17, sealing ring 18 fits tightly in place, effectively filling the gap and preventing filtered air from leaking out. It also prevents unfiltered air from mixing with the filtered air flow, ensuring that only clean, rigorously filtered air enters the compressor. A retaining ring 13 is fixedly connected to the side of sealing ring 18 away from limiting ring 17. Retaining ring 13 provides a reliable fixing point for spring 2 14, ensuring that spring 2 14 can stably exert its elastic force and helping sealing ring 18 better achieve its sealing function.

[0038] A plurality of springs 2 14 are fixedly connected to the side of the fixing ring 13 away from the limiting ring 17. The springs 2 14, through their own elastic force, can push the sealing ring 18 into close contact with the limiting ring 17, always maintaining a good sealing state at the connection, and ensuring that air will not leak even under long-term use or under certain external forces. A lid 4 is rotatably connected to one side of the main body 1. The lid 4 can protect the filter barrel 2 and other components inside the main body 1. At the same time, it can prevent external impurities from entering when closed, ensuring that the internal environment of the filter barrel 2 is relatively clean, which is conducive to the continuous and stable operation of air filtration. The interior of the lid 4 is fixedly connected to an exhaust port 5. The exhaust port 5 provides an exhaust channel for the filtered clean air, allowing the air to smoothly leave the air intake air filter structure and then enter the compressor to participate in subsequent work. The outer side of the filter barrel 2 is slidably connected to the inside of the lid 4.

[0039] Reference Figure 2 、 Figure 4 The outer side of the lid 4 is fixedly connected to a limiting component for limiting it. The limiting component can effectively control the opening and closing state of the lid 4, ensuring that the lid 4 remains tightly closed during normal operation, thereby ensuring the sealing and stability of the entire air intake filter structure. When maintenance, replacement, etc. of the filter barrel 2 are required, the lid 4 can be easily opened.

[0040] The limiting assembly includes a fixed block 6, one side of which is fixedly connected to the outside of the lid 4. This provides stable support and a fixed position for the rotation of the rotating plate 7, fundamental to the proper operation of the entire limiting assembly and ensuring that the rotating plate 7 can smoothly achieve its desired movement. The internal rotation of the fixed block 6 is connected to the rotating plate 7, which drives the limiting column 9 to move accordingly during rotation. By coordinating with other components, the opening and closing state of the lid 4 can be precisely controlled, ensuring that it can be opened or closed at the appropriate time.

[0041] A limiting post 9 is fixedly connected to the interior of the rotating plate 7. This post 9 can be accurately inserted into the corresponding position within the main body 1, providing a reliable limiter to prevent the lid 4 from accidentally opening when it should not be opened, thereby ensuring the safety and stability of the air intake filter structure during operation. The side of the limiting post 9 away from the rotating plate 7 is slidably connected to the interior of the main body 1. Two limiting rings 17 are fixedly connected to the outside of the main body 1. These two limiting rings 17 further enhance the limiting effect of the limiting post 9, constraining it from multiple directions, making the limiting function of the entire limiting assembly more stable and reliable, and better able to maintain the closed state of the lid 4.

[0042] The internal rotation of the fixed block 6 is connected to a limiting plate 8. The limiting plate 8 can change the restriction on the rotating plate 7 through its own rotation. The operation is simple and convenient, allowing the staff to easily remove the relevant restrictions when it is necessary to open the lid 4, and smoothly carry out subsequent maintenance and other operations. The bottom of the limiting plate 8 is rotatably connected to the top of the rotating plate 7. The outer side of the limiting column 9 is provided with a spring 10. The spring 10 uses its own elastic force to keep the limiting column 9 in the restricted position under normal circumstances, ensuring that the lid 4 is in the closed state. When the limiting plate 8 rotates to release the restriction on the rotating plate 7, the rebound force of the spring 10 can push the rotating plate 7 to drive the limiting column 9 out of the restricted position, making it convenient for the staff to open the lid 4 and perform the corresponding operations on the filter barrel 2.

[0043] Working principle: When the staff needs to filter the air, they can slide the connecting column 12 toward the inside of the connecting column 2 16. When the connecting column 12 slides to a certain position inside the connecting column 2 16, it can no longer slide. At this time, the connecting column 12 can be rotated to make the fixed block 2 15 rotate inside the connecting column 2 16. A limiting groove is provided inside the connecting column 2 16. When the fixed block 2 15 rotates, it will be stuck in the groove. At this time, after the connecting column 12 is loosened, the spring 2 14 will push the sealing ring 18 to contact the limiting ring 17, so that the fixed block 2 15 is effectively restricted inside the groove, thereby achieving quick docking and sealing. After the docking is completed, the connecting column 2 16 can be installed in the place where exhaust is required.

[0044] When the filter barrel 2 needs to be cleaned or replaced, the restriction of spring 10 can be cancelled by rotating the restriction plate 8. When the restriction of spring 10 is cancelled, the rotating plate 7 will be bounced open by the rebound force of spring 10. At this time, the lid 4 can be opened to replace the filter barrel 2. Under the restriction, the outer side of the restriction column 9 is connected to the inside of the main body 1, so that the filter barrel 2 can be cleaned or replaced.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
