Document Type and Number:
WIPO Patent Application WO/2017/164468
Kind Code:
A1
Abstract:
The present invention relates to a vacuum cup for a massage device and a massage device having the same, wherein an inner cup, which forms a double cup structure together with an outer cup, is configured to ascend/descend in conformity with various skin curvatures such that a stable vacuum pressure can be maintained while continuously maintaining the double cup structure with regard to various body parts that have thin skins and exhibit severe curvature changes, such as the pelvis, the back of a hand, and the top of a foot. To this end, the present invention comprises: a cylindrical body; an outer cup formed to extend outward such that the same has a larger width along the circumference of the lower end of the cylindrical body, the lower end of the outer cup being configured to contact skin; an inner cup positioned at the center of the inner space surrounded by the outer cup, the lower end of the inner cup being formed at the same height as that of the lower end of the outer cup or formed at a lower location so as to contact skin, an air intake hole being formed in the upper end of the inner cup so as to communicate with the cylindrical body such that air moves in/out; and an elastic connection film that connects the lower end of the cylindrical body and the outer surface of the inner cup such that, when the inner cup contacts skin and receives a force acting in the upward direction, the elastic connection film rotates about a thin film portion and allows the inner cup to ascend and, when the acting force disappears, returns the inner cup to the initial position by elastic force.
