Negative-pressure massage cup

Abstract

A negative-pressure massage cup includes a cup body having a first installing portion on an outer surface thereof, a vibration mechanism having an outer case, a vibrator disposed in the outer case and a second installing portion and a third installing portion respectively disposed on two opposite sides of the outer case, and a buffer rubber disposed on the second installing portion. The third installing portion is removably disposed on the first installing portion. While the negative-pressure massage cup is free falling, the cup body is rotated by a gravity loaded on the vibration mechanism so as to make the buffer rubber downward to absorb and reduce an impact caused by a collision to the negative-pressure massage cup. The vibration mechanism is prevented from damaging to the vibrator caused by a collision or noise caused by dislocating of the components in the vibrator so as to effectively improve durability.
