It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

[0024] The disclosure provides a negative-pressure massage cup, as shown in FIGS. 1-4, which includes a cup body 10, a vibration mechanism 20 and a buffer rubber 30.

[0025] In the embodiment, the cup body 10 is, but not limited to, formed as one piece by plastic injection molding, for example, the cup body 10 may also be made of acrylic or other materials. The cup body 10 has a first installing portion 11 on an outer surface thereof. There is a chamber in the cup body 10 which may be closed when contacted with human skin so that a negative pressure may be provided therein by degassing.

[0026] The vibration mechanism 20 includes an outer case 21 and a vibrator 22. The vibrator 22 is disposed in the outer case 21 and can generate vibrations. In the embodiment, the vibrator 22 is, but not limited to, an electric motor. The outer case 21 includes a first case 211 and a second case 212. In the embodiment, the first case 211 and the second case 212 are combined and sealed with each other by, but not limited to, high-frequency welding, ultrasonic welding or thermocompression welding, any other methods which can combine and seal the both with each other to prevent dust and moisture from entering the inside are available. The outer case 21 has a second installing portion 213 and a third installing portion 214 respectively disposed at a front side and a rear sided thereof. That is, the second installing portion 213 in the embodiment is formed on an outer surface of the first case 211, and the third installing portion 214 is formed on an outer surface of the second case 212. The third installing portion 214 is detachably disposed on the first installing portion 11 so as to fix the outer case 21 on the cup body 10.

[0027] The buffer rubber 30 is disposed on the second installing portion 213. In detail, the second installing portion 213 in the embodiment is, but not limited to, a recess. The second installing portion 213 as the recess has a connecting surface 213A which is of a curved shape. An inner surface of the buffer rubber 30 is of a curved shape attached on the connecting surface 213A so as to enhance the buffering effect. In the embodiment, the buffer rubber 30 is integratedly formed with the outer case 21 as one piece by double injection to make the buffer rubber 30 and the outer case 21 form sealed connection to achieve a great fixing effect, but not limited to this. Also, the buffer rubber 30 is flush with or protruded from the surface of the outer case 21. In the embodiment, the buffer rubber 30 slightly protruded from the surface of the outer case 21 so as to guarantee that the buffer rubber 30 can be impacted prior to the outer case 21 to generate a great effect of protection and buffering when the negative-pressure massage cup of the disclosure is collided. An outer surface of the buffer rubber 30 is formed with multiple recessions 31. Each recession 31 can provide crash space to effectively improve the effect of absorbing impact when the buffer rubber 30 is collided.

[0028] While the negative-pressure massage cup is free falling accidentally, the cup body 10 is rotated by a gravity loaded on the vibration mechanism 20 because the weight of the vibration mechanism 20 is heavier than the weight of the cup body 10, so as to make the buffer rubber 30 downward to absorb and reduce an impact caused by a collision to the negative-pressure massage cup. Therefore, the vibration 22 can be prevented from damage or noise caused by dislocating of internal parts thereof so as to effectively improve durability.

[0029] Furthermore, please refer to FIGS. 3 and 4, the connecting surface 213A has multiple holes 213B, and the inner wall of the buffer rubber 30 has multiple bars 32. The bars 32 are simultaneously combined and sealed with the holes 213B respectively and filled the holes 213B respectively so as to further reinforce the fixture and stability between the buffer rubber 30 and the outer case 21 when the buffer rubber 30 and the outer case 21 are being integratedly formed as one piece by double injection.

[0030] Also, the buffer rubber 30 has four corners and multiple arms 33 outward extended from the four corners respectively, and a trough 213C is extended from each of the four corners of the second installing portion 213 as the recess and the troughs 213C are extended corresponding to the arms 33 respectively. In the embodiment, each of the arms 33 and the troughs 213C are four in number, but not limited to this. Each arm 33 is disposed on each trough 213C to cover four corners of the outer case 21, which are far away from the cup body 10, so as to improve the effects of buffering and protection of the buffer rubber 30 to the outer case 21. In more detail, the outer case 21 has the four corners far away from the cup body 10 which are respectively covered by the arms 33, so that when the negative-pressure massage cup of the disclosure is free falling, the vibration mechanism 20 can be buffered and protected by the buffer rubber 30 regardless of impacting angle.

[0031] Please refer to FIGS. 3 and 4. The vibration mechanism 20 further includes a fixed inner case 23. The fixed inner case 23 is disposed on the second case 212 and received in the outer case 21. In detail, the fixed inner case 23 of the embodiment is fixed on an inner surface of the second case 212 by multiple bolts A, but not limited to this. The fixed inner case 23 and the second case 212 jointly hold and fix the vibrator 22 to effectively fix the vibrator 22 and make the vibrator 22 be not in direct contact with the first case 211, so that the vibrator 22 can be prevented from an impaction from the buffer rubber 30 through the first case 211 when the buffer rubber 30 is collided. Also, the vibration mechanism 20 further includes a vibration absorber 24. The vibration absorber 24 is elastically clamped between the vibrator 22 and the fixed inner case 23 to further enhance the protection and buffering effect to the vibrator 22. In the embodiment, the vibration absorber 24 is, but not limited to, sponge.

[0032] In particular, the first installing portion 11 of the cup body 10 includes a pair of threaded rods 111, and the third installing portion 214 of the second case 212 of the outer case 21 includes a pair of engaging cavities 214A for accommodating corresponding the threaded rods 111 respectively. Each engaging cavity 214A of the third installing portion 214 can accommodate and engage with each threaded rod 111 to fix the outer case 21 on the cup body 10. In this embodiment, the first case 211 of the outer case 21 further includes a pair fixing holes 215. The fixing holes 215 are arranged corresponding to positions of the engaging cavities 214A and communicated with the engaging cavities 214A respectively, so as to allow a pair of bolts A to respectively pass through the fixing holes 215 and then be fixed in the thread rods 111 respectively to reinforce the fixing between the outer case 21 and the cup body 10.

[0033] Please refer to FIGS. 3 and 4 again. The inner surface of the buffer rubber 30 further has a positioning indent 34, and the first case 211 of the outer case 21 is extended with a positioning protrusion 213D on the connecting surface 213A of the second installing portion 213. When the buffer rubber 30 is formed on the second installing portion 213 by double injection, the positioning indent 34 is combined and sealed with the positioning protrusion 213D to make the buffer rubber 30 have a positioning effect. Preferably, the center of the positioning indent 34 is formed with a positioning rod 341. The center of the positioning protrusion 213D is formed with a positioning hole 213E. The positioning rod 341 is combined and sealed with the positioning hole 213E to further enhance the positioning effect between the both.

[0034] While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
