Abstract
A dual-layer suction cup includes an outer body, an adhesive soft inner body and an elastic unit. The outer body is made of a hard material. The adhesive soft inner body can be attached to a smooth airtight surface and a rough airtight surface, providing an adhesion effect. The elastic unit will provide elasticity in an opposite direction after being pressed, such that the chamber in the suction cup is in a vacuum state to enhance the adhesion effect. The adhesive soft inner body and the elastic unit of the present invention greatly enhance the adhesion effect.
