A bolt 6 is installed at one end of the shell 1 away from the drive box 4, and one end of the bolt 6 abuts against the end of the filter cover 14. A roller 13 is rotatably installed inside the filter cover 14, and a cleaning mechanism is provided inside the roller 13. The cleaning mechanism can clean impurities on the filter cover 14 to ensure the filtering effect of the filter cover 14 and avoid affecting the normal operation of the equipment cooperating with the air compressor.

[0021] The cleaning mechanism includes a motor 18, bristles 12 and a threaded rod 19. The motor 18 is fixedly connected to the inside of the drum 13. A cover 34 is installed at one end of the drum 13 away from the motor 18. A connecting block 33 is fixedly connected to the middle position of the cover 34 through two fixing blocks 45. The connecting block 33 is arranged in a circular shape and an annular groove 32 is formed between the connecting block 33 and the cover 34, so that the subsequent connecting frame 44 can rotate a certain angle in the annular groove 32 to drive the sealing cylinder 26 to rotate, and can also make the connecting frame 44 slide in the annular groove 32. One end of the threaded rod 19 is fixedly connected to the output end of the motor 18, and the other end of the threaded rod 19 is fixedly connected to the optical axis 35, and the other end of the optical axis 35 is rotatably connected to the connecting block 33.

[0022] A slider 20 is threadedly connected to the threaded rod 19, and ear plates 21 are symmetrically arranged on the upper and lower sides of the slider 20. The ear plates 21 are fixedly connected to the slider 20. A connecting rod 24 is rotatably connected to the ear plates 21. The other end of the connecting rod 24 is rotatably connected to a push rod 23. The end of the push rod 23 away from the connecting rod 24 is fixedly connected to a brush plate 42. Brush bristles 12 are provided on the surface of the brush plate 42. The cooperation of the connecting rod 24, the slider 20 and the push rod 23 can drive the brush plate 42 to extend out of the drum 13 and retract into the drum 13, so that the bristles 12 can clean the filter cover 14 during use, and are stored in the drum 13 after cleaning, so as to reduce residual impurities and avoid subsequent entry into the air compressor.

[0023] A symmetrically arranged guide rod 22 is also fixedly connected between the roller 13 and the cover 34. A guide groove 46 is arranged inside the push rod 23. The guide rod 22 and the guide groove 46 are slidably matched. A guide rod 23 is fixedly connected inside the guide groove 46. The guide rod 23 and the guide rod 22 are slidably connected to the guide rod 12. The guide rod 23 serves to limit and guide the push rod 23, so that the push rod 23 can only drive the brush plate 42 to move in a straight line. The cooperation between the guide rod 12 and the guide groove 46 can make the slider 20 only move in a straight line along the threaded rod 19 when driven by the threaded rod 19.

[0024] The cleaning mechanism also includes a sealing cylinder 26, a connecting plate 16 and a connecting pipe 40. The roller 13 is rotatably connected to the air disc 11 and the interior of the roller 13 is rotatably connected to the sealing cylinder 26. An opening 27 is provided on the surface of the roller 13. The rotation of the sealing cylinder 26 can close and open the opening 27. An opening 28 is provided on the surface of the sealing cylinder 26. The brush plate 42 slidably cooperates with the opening 27 and the opening 28. Two sockets 30 are provided at the end of the sealing cylinder 26 away from the motor 2 18. Two plug rods 29 are fixedly connected to the connecting plate 16 and are slidably connected to the sockets 30 respectively. The cooperation between the plug rod 29 and the socket 30 enables the connecting plate 16 to drive the sealing cylinder 26 to rotate and also to move with the sleeve 37.

[0025] A connecting frame 44 is fixedly connected to one end of the connecting plate 16 close to the roller 13, and the other end of the connecting frame 44 passes through the annular groove 32 and extends to the inside of the roller 13 and is fixedly connected to a sleeve 37. The connecting frame 44 is rotatably connected to the annular groove 32. The sleeve 37 is sleeved on the outside of the optical axis 35, and two sections of stepped grooves 47 are arranged at intervals inside the sleeve 37. A sleeve groove 38 is arranged at the end of the sleeve 37 close to the slider 20. A card groove 41 is arranged on the inner wall of the sleeve 37 between the two sections of the stepped grooves 47. Two card blocks 36 are arranged on the outer wall of the optical axis 35. The card blocks 36 are slidably engaged with the card grooves 41. The stepped grooves 47 are arranged at the inner wall of the sleeve 37. The arrangement is to enable the block 36 and the slot 41 to be engaged or disengaged when the sleeve 37 slides, so that the subsequent sleeve 37 can be driven to rotate by the optical axis 35, or can remain stationary when the optical axis 35 rotates. A connecting tube 40 is fixedly connected to one end of the slider 20, and the connecting tube 40 is sleeved on the outside of the threaded rod 19, and a ring 39 is fixedly connected to the end of the connecting tube 40 away from the slider 20. The sleeve 37 is rotatably connected to the ring 39 through the slot 38. The cooperation between the slot 38 and the ring 39 allows the connecting tube 40 to drive the sleeve 37 to move without being driven to rotate when the sleeve 37 rotates.

[0026] The interior of the air disk 11 is hollow and an air jet groove 31 is opened at the end. The air jet groove 31 is circular and is located between the filter cover 14 and the drum 13. A fan 5 is also installed on the outer wall of the shell 1. An air inlet 25 is provided on the outer wall of the air disk 11. The fan 5 is connected to the air inlet 25. Through the arrangement of the fan 5, the air disk 11, the air jet groove 31 and other structures, when the bristles 12 clean the impurities from the filter cover 14, the cleaned impurities can be completely and effectively blown out of the outside of the shell 1.

[0027] The driving mechanism includes a motor 7, an electric push rod 9 and a support ring 10. The motor 7 is fixedly connected to the inside of the driving box 4. The output end of the motor 7 is fixedly connected to the support seat 8. The electric push rod 9 is fixedly connected to the support seat 8, and the output rod of the electric push rod 9 rotates and passes through the driving box 4. The connecting plate 16 is fixedly connected to the connecting block 33. The connecting plate 16 can rotate on the output rod of the electric push rod 9 and can also slide on the output rod. A storage cylinder 17 is also fixedly connected to the inside of the shell 1. The storage cylinder 17 is used to store the drum 13 to avoid affecting the flow of air during the subsequent operation of the air compressor. The storage cylinder 17 is slidably connected to the support ring 10, and the support ring 10 can also rotate inside the storage cylinder 17. The support ring 10 improves the stability of the drum 13 when rotating and moving. The support ring 10 is fixedly connected to the output rod of the electric push rod 9.

[0028] How it works When the filter cover 14 needs to be cleaned, the air compressor stops running, and the connecting block 33 is pushed by the output rod of the electric push rod 9 to drive the roller 13 to slide out of the storage tube 17 and then enter the interior of the filter cover 14. At this time, the motor 2 18 is started, and the motor 2 18 drives the threaded rod 19 to rotate, and the threaded rod 19 drives the slider 20 to move. The slider 20 drives the two connecting rods 24 to rotate and open through the ear plate 21. The two connecting rods 24 drive the two push rods 23 to move outward under the cooperation of the guide rod 2 43. The slider 20 will drive the connecting pipe 40 to move while moving, and the connecting pipe 40 will drive the sleeve 37 to move through the collar 39. At the same time, the rotation of the threaded rod 19 will drive the optical axis 35 to rotate. When the optical axis 35 rotates, it will drive the sleeve 37 to rotate through the cooperation of the block 36 and the slot 41, so that the sleeve 37 can both rotate and slide at the same time. When the sleeve 37 rotates, it drives the connecting plate 16 to rotate through the connecting frame 44. When the sleeve 37 is moved, the connecting plate 16 will also move in the direction away from the sealing cover 34 along the output rod of the electric push rod 9. The connecting plate 16 drives the sealing cylinder 26 to rotate through the cooperation of the plug rod 29 and the socket 30. When the sealing cylinder 26 rotates, the second opening 28 will rotate to a position aligned with the opening 1 27 on the roller 13. At this time, the brush plate 12 drives the bristles 42 to move to the bottom close to the second opening 28. At the same time, when the sleeve 37 continues to move in the direction away from the motor 18, the slot 41 on the sleeve 37 will disengage from the block 36 and enter the stepped slot 47, so that the optical axis 35 cannot drive the sleeve 37 to continue to rotate. The sleeve 37 stops driving the connecting frame 44 to rotate, and the connecting frame 44 stops driving the sealing cylinder 26 to rotate through the connecting plate 16, so that when the brush plate 42 drives the bristles 12 to extend through the openings 1 27 and the second openings 28 to the outside of the roller 13, the openings 1 27 and the second openings 28 always remain aligned. Then start the motor 7, the motor 7 drives the electric push rod 9 to rotate through the support seat 8, the output rod of the electric push rod 9 drives the entire drum 13 to rotate through the connecting block 33, so that the drum 13 drives the bristles 12 to rotate to clean the filter cover 14, because the drum 13 is arranged inside the filter cover 14, and the filter cover 14 is arranged inside the shell 1, and at the same time, due to the cooperation of the chuck 15 and the air disk 11, a separate space is formed between the inner wall of the shell 1 and the outer wall of the filter cover 14, so that the impurities cleaned from the filter cover 14 can only fall into the lower part of the shell 1, avoiding the impurities from diffusing into the air when cleaning the impurities. While the impurities are being cleaned inside the compressor, the fan 5 will also be started. When the fan 5 is started, the external air will enter the inside of the air disk 11 through the air inlet 25, and then the air disk 11 will spray it through the jet slot 31 to the separate space formed between the inner wall of the shell 1 and the outer wall of the filter cover 14. On the one hand, the impurities cleaned from the filter cover 14 can be blown out only from the air inlet pipe 2 to prevent the impurities from diffusing into the interior of the air compressor. On the other hand, the impurities on the bristles 12 can be blown off to reduce the subsequent residual impurities. At the same time, the problem of using a vacuum cleaner to absorb impurities in the prior art resulting in the impurities not being effectively sucked into the vacuum cleaner can be avoided.

[0029] When the filter cover 14 is cleaned, the motor 17 stops rotating, and the motor 2 18 is started again. The motor 2 18 drives the threaded rod 19 to rotate, thereby driving the slider 20 to move in the direction close to the motor 2 18, and then driving the brush plate 42 to move toward the inside of the drum 13 through the connecting rod 24 and the top rod 23. At this time, the slider 20 also drives the connecting pipe 40 and the sleeve 37 to move in the direction close to the motor 2 18, and the block 36 and the slot 41 are not yet engaged, so the sleeve 37 cannot rotate. The connecting plate 16 is driven by the connecting frame 44 to slide toward the sealing cylinder 26 only under the guidance of the plug rod 29. When the brush plate 42 continues to drive the bristles 12 to move completely to the inside of the drum 13, At this time, the block 36 is engaged with the slot 41, and when the threaded rod 19 rotates, the sleeve 37 can be driven to rotate through the optical axis 35, and the sleeve 37 subsequently drives the sealing tube 26 to rotate through the connecting frame 44 and the connecting plate 16, until the second opening 28 is completely staggered with the first opening 27, so that the drum 13 is closed and the bristles 12 are stored in the drum 13, so as to prevent the impurities remaining on the bristles 12 from entering the air compressor when the air compressor is inhaled during the subsequent operation, thereby affecting the normal operation of the equipment used with the air compressor, and the fan 5 is stopped when the bristles 12 are completely stored in the drum 13, so that the impurities dropped when the bristles 12 move can be completely blown out of the housing 1; Finally, the electric push rod 9 is started, and the output rod of the electric push rod 9 pulls the connecting block 33 to drive the roller 13 to slide along the air disk 11 from the filter cover 14 to the storage cylinder 17. At the same time, the support ring 10 slides along the inner wall of the storage cylinder 17 to improve the stability of the roller 13 when sliding. When the roller 13 enters the storage cylinder 17, the end of the roller 13 close to the bolt 6 will close the port of the storage cylinder 17, thereby avoiding affecting the flow of air when the air compressor is running. When the air compressor is running, air enters the shell 1 from the intake pipe 2, is filtered by the filter cover 14, and is discharged from the exhaust pipe 3, thereby achieving air filtration.
