[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. In layman's terms, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. Vacuum pumps are widely used in scientific research, industrial production, medical equipment, semiconductor manufacturing and other fields.

[0003] When the vacuum pumps currently on the market are used, they generally introduce external gas into the pump directly through the air intake port. After the existing vacuum pumps inhale the external gas containing impurities into the interior of the vacuum pump, the impurities will be directly released into the environment through the exhaust port. Therefore, we propose a vacuum pump with an environmentally friendly filtering device. Summary of the invention

[0012] Preferably, a connecting shaft is connected to the middle of the surface of the filter plate, and the connecting shaft is docked inside the cleaning brush strip.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the vacuum pump with an environmentally friendly filtering device can filter the gas sucked into the vacuum pump body through the filter frame, prevent solid particles or other impurities in the air from entering the pump, and reduce the release of pollutants from the vacuum pump body to the environment, which is more environmentally friendly, so that the vacuum pump has an environmentally friendly filtering device. Through the mutual cooperation of the rotatable cleaning brush strip and the filter plate, larger impurities can be initially filtered and cleaned at the same time, so that the vacuum pump can be convenient for regular cleaning of adhered impurities.

[0014] 1. The vacuum pump with environmentally friendly filtering device first pulls the two limit seats outward to the limit position, and then places the filter frame inside the air inlet. At this time, the side panels on both sides of the filter frame fit the edge of the air inlet, and then the staff loosens the pulled limit seat. The loosened limit seat can automatically reset inward by the elastic force of the spring, so that the limit block on the limit seat is plugged into the limit groove. The gas sucked into the vacuum pump body can be filtered through the filter frame to prevent solid particles or other impurities in the air from entering the pump, and reduce the release of pollutants from the vacuum pump body to the environment, which is more environmentally friendly, so that the vacuum pump has an environmentally friendly filtering device;

[0015] 2. The vacuum pump with an environmentally friendly filtering device, the staff holds the fixed seat and docks the filter plate from the top of the filter frame downward. As the filter plate moves downward, the inner wall of the filter frame will squeeze the docking blocks on both sides of the fixed seat until the filter plate is pushed to a position corresponding to the docking block and the reserved notch on the inner wall of the filter frame. The filter plate can be used to perform a preliminary filtration of larger impurities entering the air intake port, and the cleaning brush bar can be rotated regularly. The rotating cleaning brush bar rotates along the connecting shaft. Since the cleaning brush bar fits the surface of the filter plate, the impurities adhered to the surface of the filter plate can be brushed and cleaned as the cleaning brush bar rotates to prevent the filter plate from being blocked. Through the cooperation of the rotatable cleaning brush bar and the filter plate, larger impurities can be initially filtered and cleaned at the same time, so that the vacuum pump can be convenient for regularly cleaning the adhered impurities.

[0025] During the specific implementation, first pull the two limit seats 10 outward, and the pulled limit seats 10 drive the connected limit blocks 11 and connecting blocks 12 to move synchronously. The connecting blocks 12 move along the outside of the guide rod 14 and squeeze the spring 15 sleeved on the outside of the guide rod 14 until the limit seat 10 is pulled to the limit position, and then the filter frame 7 is placed inside the air inlet 6, and the edge of the filter frame 7 is placed above the air inlet 6.
