Description of the Related Art Airbags for massage, which repeatedly pressurize and release the body by supplying and exhausting compressed air as described above, are well known, and are made of a flexible and airtight sheet material. It is formed in a hollow structure and its shape is set according to the part to be worn on the body.For example, an upper-body type airbag to be attached to the upper half of the body, a trouser-type airbag to be attached to the lower half of the body, and a hood type to be worn from the face to the head. bag,
There are types such as airbags used for arms and legs and airbags wrapped around the head frame.

By the way, the above-mentioned airbag is mounted on each part of the body and massages the mounted part. In any shape, the compressed air is supplied to press the body, and after a set time has elapsed. The compression is released by stopping the supply of compressed air to release the compression, and this is repeated alternately.Therefore, the airbag is provided with a supply / exhaust valve for supplying and discharging compressed air. There is.

In the use of such an air bag, recent studies have revealed that body stress relief can be effectively obtained by brain stress relief.

[0005] There are β waves and α waves as brain waves involved in the stress of the brain, and those who are sick or do not work well are predominantly the β waves of the former, and on the contrary, they are well and relaxed. At that time, the latter α wave will be many.

[0006] Generally, even if massage is performed in a noisy state, the noise coming from the ears causes anxiety, and the brain is stressed. Therefore, there is a measurement result that α waves do not rise so much. Therefore, in order to reduce the stress on the body using the airbag, it is necessary to suppress the generation of noise as much as possible.

By the way, the above-mentioned supply / exhaust valve is provided in a valve box.
An inlet connected to the compressed air supply source, an outlet connected to the airbag, and an exhaust port are provided on the peripheral wall on the outlet side, and the exhaust port is closed when compressed air is supplied from the inlet inside the valve box. The valve is opened in this state to flow out to the outlet, and when the supply of compressed air from the inlet is stopped, the valve is closed to open the exhaust port, and a check valve body for discharging the air on the airbag side from the exhaust port is incorporated. It has a structure.

[0008]

However, in order to improve the massage effect, the airbag uses compressed air of high pressure to compress the body, and it is necessary to release the compression promptly. A supply / exhaust valve such as
When the air on the air bag side is discharged from the exhaust port, the exhaust gas with pressure is discharged vigorously from the small diameter exhaust port, which causes a loud exhaust noise, which causes noise and causes discomfort. However, there is a problem that such noise gives stress to the brain, and as a result, the rise of the α wave of the electroencephalogram is suppressed, and it is difficult to eliminate the stress of the body.

Therefore, an object of the present invention is to soften the exhaust noise when the air supply / exhaust valve discharges the air on the side of the airbag from the exhaust port, to comfortably use the airbag, and to further reduce body stress. It is to provide an air bag with a sound deadening function that can change the following.

[0010]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention opens a valve in a state where an exhaust port is closed when the compressed air is supplied from the inlet and causes the valve to flow out to the outlet. When the supply of compressed air is stopped, the valve is closed to open the exhaust port, and the air supply / exhaust valve that discharges the air on the outlet side from the exhaust port is installed by connecting the outlet to the air bag. The valve is provided with a structure for silencing the exhaust gas discharged from the exhaust port.

Here, the air bag may have a shape to be mounted on each part of the body, but may be formed, for example, in a boot type to be mounted on the foot.

Further, the above-mentioned sound deadening mechanism is housed inside the sound deadening container surrounding the outside of the air supply / exhaust valve so as to overlap with the external opening of the exhaust port, and passes through the filter and the filter which allows the exhaust gas discharged from the exhaust port to pass through. The sound absorbing material that reflects the exhaust gas toward the filter may be incorporated to form a structure, and the sound absorbing container may be provided with sound absorbing unevenness on the inner peripheral surface thereof.

The filter and the sound absorbing material are formed by using a gas permeable material such as sponge, and when the air supply / exhaust valve discharges the air on the airbag side from the exhaust port, the exhaust gas with pressure is The exhaust gas that has been discharged into the filter reaches the sound absorbing material, is absorbed, is reflected, and then is again discharged into the atmosphere through the filter, and is discharged from the exhaust port by the flow in such a path. Exhaust will be silenced by a filter and a sound absorbing material, and by relaxing the feeling during use, the alpha wave of the brain waves will rise and the stress of the body can be relieved.

Further, the filter may be impregnated with a fragrance or the like, and the exhaust air discharged into the atmosphere may be given a scent to improve the indoor environment.
