Description

Detailed Description of the Invention (Field of Application) The present invention relates to sequentially supplying compressed air to a compression band made up of a plurality of elastic bags attached to the arms, legs, etc. of a human body.
This invention relates to an air pine surge machine that performs pine surge by repeatedly discharging air.

(Problems with the prior art) In conventional air pine surge machines, when the pump is stopped and the pine surge is finished, residual air remains in the bag of the compression band, and this residual air leaves the bag in an inflated state. There was a problem in that it was difficult to put on the compression band the next time it was used, and if it was worn and used in this state, the compression force would decrease and the pine surge effect would be poor.

(Purpose) The present invention has been made in view of the above-mentioned problems.The purpose of the present invention is to provide a delay device that delays and stops the valve device at the end of the pine surge. To provide an air pine surge machine which automatically discharges residual air from the body and facilitates the wearing of a compression band.

(Example) Examples of the present invention will be described below with reference to FIGS. 1 to 5. A is a pump that supplies air, B is a surge tank that accumulates the air and makes it high-pressure, and C is a valve that sequentially supplies and discharges the high-pressure air supplied through the surge tank B to the bag body of the compression band, which will be described later. Device,
D is a compression band consisting of a plurality of elastic bags d arranged in a row, which are sequentially inflated and deflated by the supply or discharge of high-pressure air by the valve device C to massage the feet, etc.;
is a delay device that delays and stops the valve device C by a certain period of time when the pine surge is completed using, for example, a timer, and S is a power on/off switch.

The valve device C is connected to the compression body D as shown in FIGS. 2 to 4.
A plurality of vent holes 1 are formed radially and at regular intervals according to the number of bags d, and an air supply port 2 that communicates with the surge tank B and an exhaust port 3 to the outside are formed at the bottom. A sleeve 4 is provided with an L-shaped through hole 5 which is rotatably mounted in the sleeve 4 and connects the plurality of ventilation ports 1 and the air supply port 2 sequentially, and has an L-shaped through hole 5 formed in the outer periphery thereof. A drive device consisting of a valve body 7 having an exhaust groove 6 that sequentially communicates the port 1 and the exhaust port 3, a motor 9 and a speed reducer 10 that are fixed to the valve body 7 via a joint 8 and rotate the valve body 7. It consists of 11. 1
2 is a pipe connected to the bag body d of the compression band D, and 13 is a pipe connected to the surge tank B.

To explain its operating state, when the through hole 5 of the valve body 7 and the ventilation port 1 of the sleeve 4 coincide as shown in FIG. 5a, the air supply port 2 communicating with the through hole 5
Air is then supplied to the bag d communicating with the vent 1, causing the bag d to expand and compress the foot. In addition, in the state shown in FIG. 5b when the valve body 7 is rotated in the direction of the arrow
is closed, and the air supplied to the bag d remains inside the bag d, and the foot continues to be compressed. Further, in the state shown in FIG. 5c in which the valve body 7 is rotated in the direction of arrow
Air is supplied to the next bag body d' that communicates with the vent hole 1', and the air from the original bag body d passes through the vent hole 1 and the exhaust groove 6 to the exhaust port 3 that communicates with the exhaust groove 6. It is discharged to the outside, the bag d contracts, and the pressure on the foot is released. By repeating the above-mentioned actions, the foot is sequentially massaged from the bottom to the top, or in the opposite direction. Also, even after the switch S is opened and the air supply is stopped at the end of the pine surge, the delay device E remains active.
Therefore, the valve device C is operating for a certain period of time, and the bag body d
The residual air inside is exhausted to the outside.

(Effects) As described above, the present invention sequentially supplies air supplied by a pump to a bag in which a plurality of compression bands are connected,
By installing a delay device that delays and stops the discharge valve device, the residual air remaining in the bag after stopping the pump and completing the pine surge can be discharged, making it easier to attach the compression band the next time it is used. There is.
