Description

Technical Field

[0001] The utility model relates to the technical field of suction cups, and more specifically, to a Bernoulli suction cup with uniform suction. Background Technique

[0002] Bernoulli suction cups are widely used in handling fragile products. They are suction cups that work based on the Bernoulli principle. By generating high-speed airflows around or at the center of the suction cup, negative pressure is created inside the suction cup. Due to the pressure difference between the suction cup and the product, a suction force is formed, enabling the product to be sucked by the suction cup.

[0003] Currently, Bernoulli suction cups usually have a negative pressure cavity at the bottom, and the product is sucked by the negative pressure inside the cavity. However, in most existing Bernoulli suction cups, the negative pressure cavity is concave, and the suction force inside the cavity is greater than that at other positions at the bottom of the suction cup, resulting in uneven bottom suction. When sucking products made of some soft materials, it is easy to cause the products to be sunken. Summary of the Utility Model
