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. ## Claims ### Claim 1 A negative-pressure massage cup comprising: a cup body, comprising a first installing portion on an outer surface of the cup body; a vibration mechanism, comprising an outer case and a vibrator, the vibrator being disposed in the outer case, the vibration mechanism comprising a second installing portion and a third installing portion respectively disposed on two opposite sides of an outer wall of the outer case, and the third installing portion being removably disposed on the first installing portion; and a buffer rubber, disposed on the second installing portion and located on a side of the outer case away from the cup body and exposed outside of the outer case; wherein the cup body is configured to rotate under the action of gravity while the negative-pressure massage cup is free falling so as to make an impact area of the buffer rubber face downwardly to absorb and reduce an impact cause by a collision to the negative-pressure massage cup. ### Claim 2 (depends on 1) The negative-pressure massage cup of claim 1, wherein the second installing portion is a recess comprising a connecting surface, and the buffer rubber comprises an inner surface attached on the connecting surface. ### Claim 3 (depends on 2) The negative-pressure massage cup of claim 2, wherein the connecting surface comprises multiple holes, and the inner surface of the buffer rubber comprises multiple bars combined and sealed with the holes respectively. ### Claim 4 (depends on 2) The negative-pressure massage cup of claim 2, wherein the connecting surface is a curved surface. ### Claim 5 (depends on 2) The negative-pressure massage cup of claim 2, wherein the buffer rubber comprises multiple arms extended therefrom, the second installing portion comprises four corners, each corner is provided with a trough, the troughs are extended corresponding to the arms respectively, and the arms are disposed on the troughs respectively to cover the four corners of the outer case away from the cup body. ### Claim 6 (depends on 1) The negative-pressure massage cup of claim 1, wherein the buffer rubber is integratedly formed with the outer case as one piece by double injection, and the buffer rubber is combined and sealed with the outer case. ### Claim 7 (depends on 1) The negative-pressure massage cup of claim 1, wherein the outer case comprises a first case and a second case, and the first case and the second case are combined and sealed with each other by high-frequency welding, ultrasonic welding or thermocompression welding. ### Claim 8 (depends on 7) The negative-pressure massage cup of claim 7, wherein the vibration mechanism further comprises a fixed inner case, the fixed inner case is disposed on the second case and received in the outer case, and the fixed inner case and the second case jointly hold and fix the vibrator. ### Claim 9 (depends on 8) The negative-pressure massage cup of claim 8, wherein the vibration mechanism further comprises a vibration absorber, and the vibration absorber is clamped between the vibrator and the fixed inner case. ### Claim 10 (depends on 1) The negative-pressure massage cup of claim 1, wherein the buffer rubber is flush with or protruded from a surface of the outer case.
