Sealing structure and packing element thereof

Abstract

A sealing structure includes a first substrate having a first compartment, a second compartment and a first base surface. A first element, disposed between the first and second compartments, a second element and a third element, moves between a first initial position and a first predetermined position. The first element has a first acting surface and the second element has a second acting surface. The third element includes a body, a first sectioned part having a first main conjunctive surface, and a second sectioned part having a second main conjunctive surface. When the first element is moved to the first predetermined position, the body is clamped between the first and second acting surfaces, and the first main conjunctive surface contacts the second main conjunctive surface. Thus, the deformed third element pressing against the first base surface separates the first compartment from the second compartment.
