[0002] The vacuum suction cup is one of the actuators of vacuum equipment. The suction cup is made of nitrile rubber and has a large tearing force. Therefore, it is widely used in various vacuum suction equipment, such as in the construction, papermaking, printing, glass and other industries to achieve the task of suction and transporting thin and light objects such as glass and paper.

[0003] Mini suction cups are needed to adsorb some smaller workpieces such as substrates. When the mini suction cup is connected to high-compressed air, a uniform, thin and strong airflow is generated on the working surface of the suction cup. At this time, the gas flow rate on the upper surface of the workpiece is greater than the gas flow rate on its lower part. According to the principle that the faster the fluid speed, the lower the pressure, a pressure difference will be generated on the upper and lower sides of the workpiece, thereby forming an upward lifting force at the bottom of the workpiece, so that the workpiece is adsorbed on the bottom of the suction cup body. However, traditional mini suction cups are generally only provided with one suction channel. If the suction channel leaks when adsorbing the workpiece, the mini suction cup cannot stably adsorb the workpiece. Therefore, a suction cup exhaust structure and a mini suction cup are needed to solve the above problems. Utility Model Content
