[0002] Vacuum pumps are used in many products, such as clothing storage, vacuum suction cups and other products, and vacuum suction cups are used more frequently. When decorating houses nowadays, workers need to use vacuum suction cups to move tiles and assist workers in laying tiles.

[0003] However, when using the vacuum suction cup of today's vacuum pump, the air on the contact surface of the vacuum suction cup and the tile must be evacuated before the workers can suck up the tile. However, during the transportation process, air will enter between the vacuum suction cup and the tile, making the adsorption between the vacuum suction cup and the tile unstable, causing the tile to fall off the vacuum suction cup during transportation, and the vacuum pump on the existing vacuum suction cup cannot automatically evacuate air during this process. Therefore, an intelligent vacuum pump with automatic pressure maintenance and automatic air extraction is needed.

[0036] Working principle: the staff installs the vacuum pump on the vacuum suction cup, and then contacts the vacuum suction cup with the tile, and then presses the button 12 for 2 seconds to start the vacuum pump 7, the red indicator light is on, and when the negative pressure reaches 60 kPa, the red light goes out and the green light is on, the vacuum pump 7 runs for 3 seconds, and the vacuum pump 7 stops working, so that the air on the contact surface between the vacuum suction cup and the tile is extracted through the vacuum pump 7. At this time, the staff can move the tile. During the transportation process, gas enters the contact surface between the vacuum suction cup and the tile. When the sensor 6 detects that the negative pressure on the contact surface between the vacuum suction cup and the tile drops below 40 kPa, the two-way valve 5 and the vacuum pump 7 are started to evacuate the air again. When the negative pressure increases to 60 kPa, the vacuum pump 7 stops working.
