The material of the top block 14 is carbon steel, and the carbon steel top block 14 has higher strength.

[0039] Such as Figure 5As shown, the sealing assembly includes a sealing plate 15 and a fixing post 16. The outer side of the sealing plate 15 is rotatably connected to the front side of the air inlet 5. The sealing plate 15 is designed to seal the opening on the front side of the air inlet 5. The front side of the fixing post 16 is fixedly connected to the inside of the air inlet 5. The fixing post 16 is designed to facilitate the fixation of other structures.

[0042] Working principle: When the two-stage screw compressor is in use, the driving rod of the male screw 3 needs to be docked with an external driving source first, so that the external driving source drives the male screw 3 to rotate. When the male screw 3 rotates, it will drive the female screw 4 to rotate, so that the male screw 3 and the female screw 4 cooperate to compress the air. The air to be compressed will enter the inside of the placement chamber 2 through the air inlet 5, and the compressed air will be discharged from the inside of the placement chamber 2 through the air outlet 6. When the air enters the air inlet 5, the air will be filtered by the filter plate 7 first. After the filter plate 7 has been used for a period of time, too much dust will accumulate on the top of the filter plate 7. At this time, start the motor 8 to drive the turntable 9 to rotate. When the turntable 9 rotates, it will drive the driving block 10 to drive the driver 11 through the driving block 10, so that the driver 11 will drive the long rod 12 under the drive, and the long rod 12 will drive the cleaning plate 13, so that the cleaning plate 13 will clean the dust accumulated on the top of the filter plate 7 under the drive of the long rod 12. By driving the cleaning plate 13 by the long rod 12, the dust accumulated on the surface of the filter plate 7 is cleaned, preventing too much dust from blocking the filter holes of the filter plate 7, ensuring that the air can smoothly pass through the filter plate 7, and enabling the compressor to operate normally.

[0043] When the cleaning plate 13 is cleaning the dust on the surface of the filter plate 7, the top block 14 on the long rod 12 will push open the sealing plate 15, so that the cleaning plate 13 can push the dust out of the inside of the air inlet 5. When the long rod 12 and the cleaning plate 13 are driven by the driver 11 and reset, the spring 17 will push the sliding sleeve 18, so that the sliding sleeve 18 pulls the driving strip 19, and the driving strip 19 will also pull the sealing plate 15, so that the sealing plate 15 seals the front opening of the air inlet 5, preventing external foreign objects from entering the inside of the air inlet 5 through the front opening of the air inlet 5, and also allowing air to smoothly enter the placement chamber 2 through the air inlet 5.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
