The disclosure relates to a negative-pressure massage cup, particularly to a negative-pressure massage cup with a buffer rubber which can prevent damage caused by a collision.
Modern people are suffered from various pressures caused by a fast-paced life, e abnormal diet, lacking of exercise, and long-term poor posture, etc., these often lead to problems such as body aches or poor blood circulation. Therefore, various massage-related products have been developed on the market. By these products, users can achieve the effects of relaxing and improving body functions. Among them, the negative-pressure massage cup can achieve effects similar to cupping, so as to promote the blood circulation of the skin to relax the muscles by various degrees of suction, and the effect of enhancing blood circulation and massaging can be further achieved by a vibrator on the negative-pressure massage cup.
However, general negative-pressure massage cups are made of plastic or acrylic, and the vibrator is usually installed on the outside of the negative-pressure massage cup. Therefore, when the negative-pressure massage cup is accidentally dropped, the negative-pressure massage cup will be rotated by the gravity because the weight of the vibrator is heavier than the cup body of the negative-pressure massage cup, so that the vibrator will be turned downward to directly hit into the ground or other objects, and this further leads to damage to the vibrator or noise caused by shifting of internal parts.
In view of this, the inventors have devoted themselves to the above-mentioned prior art, researched intensively and cooperated with the application of science to try to solve the above-mentioned problems. Finally, the invention which is reasonable and effective to overcome the above drawbacks is provided.
An object of the disclosure is to prevent the vibration mechanism 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.
To accomplish the above object, the disclosure provides a negative-pressure massage cup, which includes a cup body, a vibration mechanism, and a buffer rubber. The cup body has a first installing portion on an outer surface thereof. The vibration mechanism includes an outer case and a vibrator. The vibrator is disposed in the outer case. The vibration mechanism has a second installing portion and a third installing portion respectively disposed on two opposite sides of the outer case. The third installing portion is removably disposed on the first installing portion. The buffer rubber is disposed on the second 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.
In an embodiment of the disclosure, the second installing portion is a recess and comprises a connecting surface, and an inner surface of the buffer rubber is attached on the connecting surface.
In an embodiment of the disclosure, the connecting surface comprises multiple holes, and an inner wall of the buffer rubber comprises multiple bars, and the bars are combined and sealed with the holes respectively.
In an embodiment of the disclosure, the connecting surface is a curved surface.

In an embodiment of the disclosure, 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.
In an embodiment of the disclosure, 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.
In an embodiment of the disclosure, 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.
In an embodiment of the disclosure, the vibration mechanism further comprises a vibration absorber, and the vibration absorber is elastically clamped between the vibrator and the fixed inner case.
In an embodiment of the disclosure, the buffer rubber is flush with or protruded from a surface of the outer case.
The negative-pressure massage cup of the disclosure uses the buffer rubber disposed on a side of the outer case, which is far away from the cup body, to make the buffer rubber serve as a buffer for impact when the negative-pressure massage cup is free falling. This can absorb the impact of collision, so as to prevent the vibrator from being damaged or generating noise because of dislocation of the internal parts to effectively improve durability.

The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.
The disclosure provides a negative-pressure massage cup, as shown in
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.
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.

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.
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.
