[0003] Currently, during operation, air compressors generate significant noise at their air inlets due to rapid airflow. This noise can impact the surrounding environment and human health. While some noise reduction solutions exist for air compressors, their installation is complex, and maintenance requires considerable time and manpower, increasing maintenance costs. Therefore, to address this issue, those skilled in the art are dedicated to developing a noise reduction structure for air compressors. Utility Model Content

Addressing usage issues, it incorporates a fixing mechanism and noise reduction components. By installing noise reduction components and multiple dust filters at the air inlet of the air compressor body, the noise generated at the air inlet can be effectively reduced. Furthermore, the overall design is modular, making installation and removal convenient and facilitating maintenance by staff, thus demonstrating good practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A noise reduction structure for an air compressor includes an air compressor body with an air inlet on the right side; a fixing mechanism including an annular fixing block and a hexagonal positioning block fixedly connected to the right side of the air inlet; a circular fixing plate on the right side of the annular fixing block; multiple ventilation openings on the right side of the circular fixing plate; a dust filter screen in each ventilation opening; a threaded groove on the right side of the hexagonal positioning block; and bolts on the right side of the circular fixing plate; and a noise reduction component including a circular connecting block inside the annular fixing block; a placement groove on the right side of the circular connecting block; a first hexagonal through groove on the left inner wall of the placement groove; a hexagonal reinforcement fixedly connected to the left inner wall of the placement groove; glass wool placed in the placement groove; a circular mounting plate on the right side of the circular connecting block; and a second hexagonal through groove on the right side of the circular mounting plate.

[0029] Reference Figures 1-6 A noise reduction structure for an air compressor includes an air compressor body 1, with an air inlet 2 provided on the right side of the air compressor body 1.

[0030] The system also includes a fixing mechanism, which comprises an annular fixing block 3 and a hexagonal positioning block 4 fixedly connected to the right side of the air inlet 2. The hexagonal positioning block 4 penetrates the inner wall of the first hexagonal through-slot 12, the inner wall of the hexagonal reinforcement 13, and the inner wall of the second hexagonal through-slot 16, and is slidably connected to the inner walls of the first hexagonal through-slot 12, the hexagonal reinforcement 13, and the second hexagonal through-slot 16. This ensures the stability of the circular connecting block 10 and the circular mounting plate 15 after installation and prevents them from shifting. A circular fixing plate 5 is provided on the right side of the annular fixing block 3, and a reinforcing block 17 is fixedly connected to the left side of the circular fixing plate 5. The left side of the reinforcing block 17 is connected to the circular fixing plate 15. The right side of the circular mounting plate 15 is attached, and the left side of the reinforcing block 17 is provided with a hexagonal positioning groove 18. The right end of the hexagonal positioning block 4 is slidably connected to the inner wall of the hexagonal positioning groove 18, which can ensure the stability of the circular fixing plate 5 after installation and prevent it from shifting. The right side of the circular fixing plate 5 is provided with multiple ventilation openings 6, and each ventilation opening 6 is provided with a dust filter 7. The dust filter 7 can prevent dust and other impurities in the air from entering the air compressor body 1 through the air inlet 2. The right side of the hexagonal positioning block 4 is provided with a threaded groove 8, and the right side of the circular fixing plate 5 is provided with a bolt 9. The left threaded end of the bolt 9 passes through the circular fixing plate 5 and the reinforcing block 17 and is threadedly connected to the threaded groove 8.

[0031] The system also includes a noise reduction component, which includes a circular connecting block 10 disposed inside the annular fixing block 3. The circular connecting block 10 is slidably connected to the inner wall of the annular fixing block 3. A placement groove 11 is provided on the right side of the circular connecting block 10. A first hexagonal through groove 12 and multiple first vent holes 20 are provided on the left inner wall of the placement groove 11. A hexagonal reinforcement member 13 is fixedly connected to the left inner wall of the placement groove 11. The first hexagonal through groove 12 and the hexagonal reinforcement member 13 allow a hexagonal positioning block 4 to pass through, thereby positioning the circular connecting block 10. Glass wool 14 is placed inside the placement groove 11. This is existing technology, and its interior has a large number of micropores and irregular fiber structures, which can effectively absorb, reflect, and scatter sound waves, thereby achieving a noise reduction effect. A circular mounting plate 15 is provided on the right side of the circular connecting block 10. The right side of the circular connecting block 10 is provided with a second hexagonal through slot 16 and multiple second vent holes 21. The second hexagonal through slot 16 allows the hexagonal positioning block 4 to pass through, thereby positioning the circular mounting plate 15. The right side of the circular connecting block 10 is fixedly connected with an annular permanent magnet 19. The annular permanent magnet 19 cooperates with the circular mounting plate 15. The circular mounting plate 15 is made of iron and can be magnetically attracted to the annular permanent magnet 19, thereby realizing convenient splicing between the circular connecting block 10 and the circular mounting plate 15, so as to facilitate the subsequent replacement of the glass wool 14. The left side of the circular connecting block 10 is fixedly connected with a first annular sealing ring 22 and a second annular sealing ring 23. The left side of the first annular sealing ring 22 and the left side of the second annular sealing ring 23 are both in contact with the right side of the air inlet 2, which can ensure that the airflow passes stably through the glass wool 14 and then enters the air compressor body 1 through the air inlet 2.

[0032] In this utility model, when the air compressor body 1 starts running, air enters through multiple vents 6 on the circular fixed plate 5, and then passes through multiple dust screens 7, multiple second vents 21 on the circular mounting plate 15, glass wool 14 and multiple first vents 20 on the circular connecting block 10 in sequence, and finally enters the air compressor body 1 stably through the air inlet 2. During this process, the glass wool 14 can effectively absorb sound wave energy through its porous structure, thereby reducing the airflow noise at the air inlet 2. At the same time, the multiple dust screens 7 can effectively block dust and other impurities from entering the air compressor body 1.

[0033] When the noise reduction component needs maintenance after a period of use, the staff can use tools to remove the bolts 9, and then take out the circular fixing plate 5 and the noise reduction component from the inside of the annular fixing block 3 in sequence. Then, overcome the magnetic force between the annular permanent magnet 19 and the circular mounting plate 15, separate the circular connecting block 10 and the circular mounting plate 15, and then maintain and replace the glass wool 14 in the placement groove 11. After the replacement is completed, the circular mounting plate 15 and the annular permanent magnet 19 are magnetically attracted to each other to realize the splicing of the entire noise reduction component. During this period, the multiple dust screens 7 on the circular fixing plate 5 can also be cleaned as needed.

[0034] After all maintenance is completed, first place the noise reduction component inside the annular fixing block 3. During placement, ensure that the hexagonal positioning block 4 passes sequentially through the first hexagonal through slot 12 on the circular connecting block 10, the hexagonal reinforcement 13, and the second hexagonal through slot 16 on the circular mounting plate 15. The hexagonal cross-section's limiting effect ensures that there is no radial offset between the circular connecting block 10 and the circular mounting plate 15 after installation. Then, place the circular fixing plate 5 inside the annular fixing block 3, ensuring that the right end of the hexagonal positioning block 4 is inserted into the hexagonal section of the reinforcement block 17. The circular fixing plate 5 is installed in the hexagonal positioning groove 18 to ensure that there is no radial offset after installation. Finally, the bolt 9 is passed through the right side of the circular fixing plate 5 and tightened with the threaded groove 8 to make the circular fixing plate 5 and the hexagonal positioning block 4 stably connected, thus completing the stable installation of the entire device. The entire maintenance process is relatively convenient. Only one bolt 9 needs to be removed to carry out the maintenance operation. Moreover, the hexagonal positioning block 4 not only constrains the relative position of the circular connecting block 10 and the circular mounting plate 15, but also serves as the installation reference of the circular fixing plate 5, effectively reducing the actual maintenance workload and maintenance cost.

[0035] It should be noted that this application mainly demonstrates the noise reduction treatment at the air compressor inlet. In actual use, the air compressor outlet will also generate significant noise due to the rapid airflow. Therefore, the same fixing mechanism and noise reduction components need to be installed at the air compressor outlet to achieve better noise reduction effect.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
