[0002] An air compressor refers to an air compressor, which is a device used to compress gas. Its working principle is divided into two categories: positive displacement and dynamic according to different ways of compressing air. The positive displacement compressor compresses air by changing the volume, while the dynamic compressor uses the centrifugal force generated by a high-speed rotating impeller to compress air.

[0003] Existing air compressors with filtering functions have multiple air compression cylinders, and each air compression cylinder has a filtering function and requires regular cleaning of the filtering components. Maintenance personnel need to disassemble and assemble and clean multiple filtering components in sequence. The whole process of disassembly, assembly and cleaning is too complicated and not easy to operate, and the overall maintenance time is also relatively long. Therefore, an air compressor with a filtering function is needed to solve the above problems. Content of the Utility Model

A limiting ring 912 is fixedly connected to the surface of the guiding slide rod 911. By setting the pressing ring 910, the air filter mesh 901 and the bidirectional scraping plates 907, when it is necessary to clean the filtering components inside multiple air compression cylinders 7, at this time, hold the pressing ring 910 with hand and press the pressing ring 910 downward. The downward movement of the pressing ring 910 will drive the air filter mesh 901 and the sealing plug 902 to slide out from the inner wall of the sealing sliding groove 906 opened at the bottom of the filtering ring 8. The two bidirectional scraping plates 907 fixedly connected to the bottom of the filtering ring 8 will clean the dust and other sundries on the surface of the air filter mesh 901 during the downward movement of the air filter mesh 901. Thus, it can be realized that the cleaning of multiple filtering components can be achieved without disassembling and assembling the filtering components one by one, making the cleaning process of the filtering components more convenient, and also bringing convenience to the maintenance personnel, and the time cost spent in the overall cleaning process is also less.

[0025] Four moving wheels 2 are arranged at the bottom of the air storage tank 1, and a damping plate 3 is arranged at the top of the air storage tank 1.

[0026] Four mounting seats 4 are arranged at the top of the damping plate 3, and a copper wire motor 5 is arranged at the top of the four mounting seats 4.

[0027] A heat dissipation fan 6 is arranged on one side of the copper wire motor 5, and an air compression cylinder 7 is arranged at the top of the copper wire motor 5.

[0028] The air filter mesh 901 is arranged inside the filtering ring 8. The spring 904 is located on the inner wall of the installation groove 903. The bottom of the sealing fixing ring 905 is fixedly connected to the top of the filtering ring 8. The sealing sliding groove 906 is slidably connected to the sealing plug 902. The bottom of the guiding slide rod 911 is fixedly connected to the top of the damping plate 3.

[0029] An air inlet 10 is arranged on one side of the filtering ring 8. An air duct 11 is arranged on the surface of the air compression cylinder 7. One end of the air duct 11 is fixedly connected to the surface of the air storage tank 1.

[0030] The top of the air storage tank 1 is provided with an air outlet valve port 12, and the top of the air outlet valve port 12 is provided with a control console 13. One side of the shock-absorbing plate 3 is fixedly connected with a push rod 14. By setting the pressing ring 910 and the guiding slide rod 911, the guiding slide rod 911 will slide on the inner wall of the pressing ring 910. The guiding slide rod 911 can provide a guiding effect for the downward movement of the pressing ring 910, so that the pressing ring 910 will not shift in position during the downward movement and affect the cleaning of the air filter screen 901 by the integrated cleaning device 9.

[0031] The working principle and usage process of the present utility model: When it is necessary to clean the filter components inside multiple air compression cylinders 7, at this time, hold the pressing ring 910 with the hand and press it downward.

The sealing plug 902 fixedly connected to the connecting column 908 and the air filter screen 901 fixedly connected to the sealing plug 902 will also move downward accordingly. At this time, the air filter screen 901 and the sealing plug 902 will slide out from the inner wall of the sealing chute 906 opened at the bottom of the filter ring 8. At the same time, during the downward movement of the air filter screen 901, the spring 904 will also be affected by the force and expand and contract accordingly. When the integrated base 909 moves downward to the position where it contacts the limit ring 912, at this time, the integrated base 909 can no longer move downward. At the same time, the part of the air filter screen 901 that needs to be cleaned will slide out from the filter ring 8. Two bidirectional scraping plates 907 fixedly connected to the bottom of the filter ring 8 will clean the dust and other sundries on the surface of the air filter screen 901 during the downward movement of the air filter screen 901. After the surface of the air filter screen 901 is cleaned, at this time, slowly reduce the force applied to the pressing ring 910. The force received by the spring 904 will be reduced synchronously and will drive the air filter screen 901 and the sealing plug 902 to reset to the inside of the filter ring 8 to continue to perform the filtering function.
