Description

  The present invention belongs to a vibration case in a negative pressure cup, and particularly relates to a vibration case in a negative pressure cup that achieves waterproofing, anti-collision, and noise attenuation functions by using a hermetic reinforcement structure.

  A negative pressure cup is a health device that enhances health by cupping on the surface of the body and stimulating the skin by negative pressure suction. In order to further enhance the health effect of the negative pressure cup, a vibration case can be further installed on the negative pressure cup. Therefore, by simultaneously oscillating the negative pressure suction, blood circulation is promoted and the health is further improved.

  Since water breaks into the vibration case, it is necessary to enhance the waterproof function of the vibration case for effective use for a long time. Further, when the vibration motor as a power source of the vibration case is operated, it often hits the case main body, so that noise is generated, the usable period is shortened, and energy is wasted.

  As a waterproof function, a general structure is an O-ring (also called O-ring or O-ring). The O-ring is a waterproof gasket as a mechanical part having an annular shape, and is usually an elastic body, and its cross section is often circular. In general, when an O-ring is mounted and fixed in a groove and the parts are assembled, the mounted O-ring is pushed by two or more parts, so that a sealed joint is obtained. It is formed.

  O-rings are inexpensive, simple in structure, reliable, easy to install, and capable of receiving pressures of several tens of pascals (kips), so they have a sealed structure. It is used for fixing in a state where they do not move relative to each other, or for movement in a state where the parts having a sealed structure move relative to each other. For example, a rotary pump shaft or a hydraulic cylinder piston.

  However, the O-ring has a simple structure and the surface to be fixed is not properly fixed. In addition, the O-ring is subject to high or low temperature, chemical corrosion, vibration, abrasion, and movement due to changes in the usage environment. Due to the fact that defects are likely to occur, the structure needs to be further improved, other than selecting an appropriate elastic material according to environmental conditions.

  Therefore, at present, there is still a need for a proposal for solving the above-described problem that the conventional O-ring is deteriorated or loses the waterproof effect due to the assembling method.

  In addition, with regard to the functions of collision prevention and noise attenuation, the vibration motor uses an eccentric wheel and generates vibration by converting the eccentric wheel to reciprocal motion between rotation and reciprocation. Instead of being fitted to the vibration case and packed, it is generally fixed with a simple frame, and since the frame cannot fix the vibration motor effectively, the vibration motor can be shaken with the frame even when it operates. It is moving and easily hits the vibration case. Over time, the vibration case is destroyed, resulting in product damage.

  In addition to damage to the vibration case, random vibration of the vibration motor destabilizes the vibration of the vibration case, which affects work due to performance degradation and wastes energy.

  Furthermore, when the vibration motor is activated, vibration noise originally occurs. Therefore, adding noise generated by the vibration of the vibration motor and the collision of the vibration case makes the sound more harsh, which is more user-friendly. The noise has a great influence, especially in a healthy working environment and an environment of long-term use, and the noise has a more prominent influence on the user, and further, the willingness to use is reduced and the function of the vibration case cannot be exhibited.

  In view of the above problems, it is clear that the prior art still has room for improvement and needs to be solved.

  Through the above, the present inventors have improved, and after long-term research and development, implemented the vibration case in the negative pressure cup that achieves waterproofing, anti-collision, and noise damping functions of the present invention.

  In addition, another object of the present invention is to provide a vibration case in a negative pressure cup that achieves hermetic sealing waterproof, collision prevention, and noise attenuation functions. The ring can solve the problem of deterioration or loss of the waterproof effect due to the assembly method, and the best waterproof effect can be obtained.

  In addition, another object of the present invention is to provide a vibration case in a negative pressure cup that achieves hermetic sealing, waterproof, anti-collision, and noise attenuation functions, using a noise reduction cover and a cushion cushion.
