Description

Vibration box on negative pressure cup body with functions of water prevention, collision prevention and noise reduction by strengthening sealing

Technical Field

The invention belongs to a vibration box on a negative pressure cup body, in particular to a vibration box on a negative pressure cup body, which utilizes a reinforced closed structure to achieve the functions of water prevention, collision prevention and noise reduction.

Background

The negative pressure cup body is a health care device which covers the surface of the body and stimulates the skin by utilizing a negative pressure suction mode so as to achieve the function of body building; in order to enhance the body-building effect of the negative pressure cup body, the negative pressure cup body can be provided with a vibration box so as to provide vibration in the negative pressure suction process, promote blood circulation and further enhance the body-building effect.

In order to be effectively used for a long time, the vibration box must prevent moisture from entering the box to cause damage, so that the waterproof function needs to be enhanced; in addition, the vibration box utilizes the vibration motor to provide a vibration source, and the vibration motor often collides with the box body when working, so that noise is generated, the service life is shortened, and energy is wasted.

For waterproof function, a common structure is an O-ring (also known as an O-ring, an O-ring), which is a mechanical gasket in the shape of a circular ring, usually an elastomer, with a cross section usually circular, which is usually fixed in a groove and compressed by two or more components during assembly, thus creating a sealed interface.

Because it is inexpensive, simple to manufacture, functionally reliable, simple to install, and the O-ring can withstand pressures of tens of pascals (thousand pounds), the O-ring can be used in static applications as well as in dynamic applications where there is relative motion between components, such as the shaft of a rotary pump and the piston of a hydraulic cylinder.

However, because of its simple structure, its fixed contact surface is usually not properly fixed, and it is easy to fail in the course of high or low temperature, chemical corrosion, vibration, abrasion and movement due to the change of the use environment, it is necessary to further improve its structure in addition to selecting proper elastomer material according to the environmental conditions.

Therefore, there is still a need for a solution to the above-mentioned problem that the conventional O-ring is easily subjected to variation of assembling manner to reduce or lose the waterproof effect.

In addition, for the functions of collision prevention and noise reduction, the working principle of the vibration motor is that an eccentric wheel mode is adopted, and the eccentric wheel is rotated to swing to cause vibration, but the vibration motor is not completely sealed in the vibration box and is usually fixed by a simple frame, so the frame cannot effectively fix the vibration motor, and the vibration motor can shake on the frame when in work, so the vibration motor is easy to collide with the vibration box, and the structure of the vibration box can be damaged after long-term use, and the product is damaged.

In addition to damage of the vibration box, the vibration of the vibration box is unstable due to the random shaking of the vibration motor, so that the efficiency is reduced to influence the work, and the energy is wasted.

Moreover, the work of the vibration motor can generate vibration noise, and the vibration motor shakes and impacts the vibration box, so that the generated noise is more obvious and harsh, the experience of a user is seriously influenced, particularly the noise has more obvious influence on the user in health care work and long-term use environments, and even the use will is reduced, and the function of the vibration box cannot be exerted.

In view of the above-mentioned shortcomings, it is obvious that there is still room for improvement in the conventional art.

Therefore, the inventor sets out improvement, and after long-term research and development and implementation, the vibration box on the negative pressure cup body can be finally completed, so that the functions of water prevention, collision prevention and noise reduction can be achieved by strengthening and sealing the part.
