Description

[Detailed explanation of the idea] [Purpose of invention]

(Industrial Application Field) This invention relates to an improvement of a pressure regulating device in a pine surge device that uses compressed air. (Prior Art) A pine surge device that uses compressed air is mainly composed of a compressor, a pressure regulator, a distributor, and a pine surge body. The pine surge body is, for example, a plurality of bags arranged in a row in a mat shape, and an air supply pipe from a distributor is individually connected to each bag. This type of pine surge device uses a pressure regulator to adjust the compressed air from the compressor to a constant pressure and sends it to the distributor, which inflates and deflates each bag of the pine surge body in turn, thereby applying pressure to the body. It is a device that provides stimulation, and in many cases, the opening degree of the valve that makes up the pressure adjustment device can be adjusted, so that the degree of pressing force can be selected by changing the pressure or flow rate of the air being supplied. It is composed of In addition, the pine surge device mentioned above has
A timer is installed to turn off the power after a set time has elapsed for convenience of use. (Problem to be solved by the invention) However, since the above-mentioned pine surge device has a structure in which the opening degree of the valve of the pressure regulating device is directly adjusted by the user's operation, it is necessary to use a timer together with the device when sleeping, for example. In this case, the pine surge operation due to a constant pressing force suddenly stops when the power is turned off. For this reason, in the past, when starting or stopping the pine surge device using a timer, there was a problem in further improving the comfort provided to the user. (Purpose of the invention) This invention was made by focusing on the conventional problem, and it is possible to set the timer and use the pine surge device without causing discomfort after starting or before stopping. The object of the present invention is to provide a pressure adjustment device for a pneumatic pine surger that can realize a more comfortable pine surge operation.

[Structure of the idea]

(Means for Solving the Problems) A pressure regulating device for a pneumatic pine surge device according to this invention is a pressure regulating device installed in an air supply path from a compressor to a pine surge body, and includes a timer and a pressure regulating device for a pine surge device. By providing a signal generator that is turned ON and OFF and continuously generates a valve drive signal, and a valve mechanism whose opening degree gradually increases or decreases depending on the valve drive signal, the conventional problems can be solved. Solve. In addition, as a signal generator in the above configuration,
For example, there are those that regularly generate a constant valve driving signal, and those that generate a valve driving signal whose output increases or decreases over time. Further, as the valve mechanism in the above configuration, there are one that constitutes a part of the air supply route and directly opens and closes the passage, and one that opens and closes the air supply route with respect to the outside air. (Operation of the invention) The pressure regulating device for a pneumatic pine surge device according to this invention is configured to increase the pressure or flow rate of air toward the pine surge body over time by a valve drive signal that is continuously generated after activation by a timer. Gradually change the opening degree of the valve mechanism, and just before the timer stops, the valve drive signal gradually changes the opening degree of the valve mechanism so that the pressure or flow rate of air to the pine surge body side decreases over time. This improves the comfort of the user when using the pine surger, for example, when waking up or going to bed. (Example) This invention will be explained below based on the drawings. FIGS. 1 and 2 are diagrams illustrating an embodiment of this invention. That is, the pine surge device 1, as its structure is schematically shown in FIG. The pine surge body 5 connected in a pine shape and the feed pipes 6, 7, 8
The configuration is such that they are connected in order. At this time, between the distributor 4 and the pine surge body 5, the plurality of ventilation holes of the distributor 4 and each bag body 5a are individually connected. The pressure regulator 3 includes a timer 9 and a signal generator 10 that is turned on and off by the timer 9 and continuously generates a valve drive signal.
and a valve mechanism 11 whose opening degree gradually increases or decreases depending on the valve drive signal. The timer 9 is electrically connected to a power source and the compressor 2 (not shown), and the start and stop times can be set arbitrarily. Further, the signal generator 10 in this embodiment sends a valve drive signal, which is a constant electrical pulse signal, to the valve mechanism 11. The valve mechanism 11, as shown in FIG.
An upper casing 13 into which a step motor 12 is fixed and an output shaft 12a of the motor 12 is screwed is connected to a lower casing 14 provided with an air supply path. A closing member 16 that forms a pressure chamber 15 with the lower casing 14 is attached. The output shaft 12a can be moved in its axial direction by an amount corresponding to the screw pitch by intermittent rotation of the step motor 12. Both casings 1
In the space 17 formed between 3 and 14, there is a disc-shaped member 18 in which the tip of the output shaft 12a is abutted and engaged, and an upper end of the spool 19 protruding from the lower casing 14 is abutted and engaged. A flanged cylindrical member 20 is provided, and a coil spring 21 is interposed between both members 18 and 20. The lower casing 14 has inlet and outlet connection ports 22 and 23 formed on both sides, and the spool 1 that is movable up and down in the center.
9 is provided in a penetrating state. Each connection port 2
2 and 23 are communicated with flow passages 22a and 23a that extend toward the center of the lower casing 14, bend downward, and open into the pressure chamber 15. The spool 19 is inserted into a vertical portion of the flow path 23a of the outlet side connection port 23, and is inserted into the flow path 23a of the outlet side connection port 23.
It has a flange-like valve portion 19a that opens and closes the pressure chamber side opening 24 of 3a, and its lower end is held by a recess 16a formed in the closing member 16 so as to be vertically movable. Further, a coil spring 25 is interposed between the valve portion 19a and the closing member 16. In the valve mechanism 11, the feed pipe 6 from the compressor 2 is connected to the inlet side connection port 22, and the feed pipe 7 to the distributor 4 is connected to the outlet side connection port 23. The above-described pine surge device 1 supplies compressed air from a compressor 2 to a valve mechanism 11, and then to a distributor 4, which sequentially inflates and deflates each bag body 5a of a pine surge body 5 to provide pressure stimulation to the body. give. Here, if the timer 9 is set so that the pressure regulator 1 is activated when the user wakes up, the pressure regulator 3 turns on the power at a scheduled time and operates the compressor 2, and the signal generator 1
Continuously generates a positive valve drive signal from 0. In the valve mechanism 11 driven by the valve drive signal, the output shaft 12 rotates as the step motor 12 rotates in the positive direction by a predetermined angle.
a gradually descends in accordance with the screw pitch, and the disc-shaped member 18, coil spring 21 and cylindrical member 20
By pushing the spool 19 downward through the
Increase air flow to. Therefore, the pine surge device 1 gradually increases the pine surge pressure on the user over a predetermined period of time after being activated. Furthermore, if the timer 9 is set so that the pine surge device 1 stops at a desired time when the user goes to bed, a negative valve drive signal is continuously generated from the signal generator 10 at a predetermined time immediately before the stop. The step motor 12 rotates in the opposite direction, and as the output shaft 12a rises, the spool 1 is rotated by the action of the coil spring 25.
By returning 9 upward, the degree of opening of the opening 24 is gradually reduced and the air flow rate to the distributor 4 is reduced. Therefore, the pine surge device 1 gradually weakens the pine surge pressure on the user within a predetermined period of time before stopping, and at the set time, the power is turned off and the pine surge device 1 stops. When using the timer 9 without setting it, for example, the pressure can be adjusted by operating a pressure adjustment switch provided on the signal generator 10 to rotate the step motor 12 in the forward or reverse direction. It is possible to adjust it arbitrarily. FIGS. 3 to 5 are diagrams illustrating other embodiments of this invention. That is, the pine surge device 1 in this embodiment
As the structure is schematically shown in FIG. 3, it includes an electric compressor 2, a pressure regulator 30,
The compressor 2, the distributor 4, and the pine surge body 5 are connected in order through feed pipes 26 and 27, and the compressor 2 and the distributor 4 are connected to each other in order. A branch pipe 28 to a pressure regulator 30 is connected to the feed pipe 26 between them. The pressure regulator 30 includes a timer 31 electrically connected to a power source and the compressor 2 (not shown).
, a signal generator 32 that is turned on and off by the timer 31, and a valve mechanism 33. The signal generator 32 includes a pulse generator 32a that generates a periodic pulse signal, and an integrator 32b.
and an amplifier 32c are connected in this order. The valve mechanism 33, as shown in FIG.
An air outlet cylinder 37 having an exhaust port 35 and a conical dish-shaped valve seat part 36 is fixed to a standing wall part 34a provided at one end of the base 34, and a conical valve is provided at the tip inside the air outlet cylinder 37. Sliding valve 3 with head 38
9 is slidably inserted into the lead-out tube 37 in the axial direction (left-right direction in the figure). Further, an air introduction hole 40 is provided on the rear side of the valve seat portion 36 of the outlet cylinder 37.
is formed, and the branch pipe 28 is connected to this air introduction hole 40. Further, a steel frame 41 is fixed to the other end of the base 34, and the frame 41 includes a hollow coil 42 therein.
one end is connected to the rear end of the sliding valve 39, and
A solenoid plunger 43, the other end of which is inserted inside the coil 42, is held slidably in the axial direction thereof. Furthermore, an amplifier 32c of the signal generator 32 is connected to the coil 42. The pine surge device 1 equipped with the above-mentioned pressure regulator 30 can set the startup timing using the timer 31, and then turn on the power at the set time and adjust the compressor 2.
At the same time, the signal generator 32 generates a valve driving signal. At this time, the signal generator 32 is the fifth pulse generator 32a.
While generating a periodic pulse signal as shown in FIG. 5a, the integrator 32b integrates the pulse signal using the positive output as shown in FIG. 5b,
Further, the amplifier 32c continuously generates a valve driving signal by amplifying the input signal from the integrator 32b as shown in FIG. 5c. Further, in the valve mechanism 33 driven by the valve drive signal, as the input voltage to the coil 42 increases, the solenoid plunger 43 is gradually and strongly attracted by the electromagnetic action of the coil 42, and at the same time, the solenoid plunger 43 is attracted By moving the valve train 39 toward the rear end of the outlet tube 37 (left and right in the figure), the opening degree of the exhaust port 35 is gradually reduced, and the amount of air flowing out from the outlet tube 37 is gradually reduced.
As shown in FIG. 5d, the air pressure to the distributor 4 side is increased. In addition, when the stop time is set with the timer 31, the integrator 32b uses a negative output to continuously generate a valve drive signal in which the integrated voltage gradually decreases, and the attraction is caused by the electromagnetic action of the coil 42. While gradually weakening the force, the pressure of the air introduced from the branch pipe 28 moves the slide valve 39 toward the opening tip of the outlet tube 37, thereby gradually increasing the opening degree of the exhaust port 35, and the air is then fed. By increasing the amount of compressed air discharged through the tube 28, the air pressure to the distributor 4 side is reduced. Therefore, similarly to the previous embodiment, after activation by setting the timer 31, the pine surge device 1 operates to gradually increase the pressing force of the pine surge body 5 against the user, and the timer 31 is activated. Immediately before stopping according to the setting, the pressing force on the user is gradually weakened until the stop is reached.

[Effect of the idea]

As explained above, the pressure regulating device for a pneumatic pine surge device of this invention is a pressure regulating device that is installed in the air supply path from the compressor to the pine surge body, and is controlled by a timer and the timer to turn on and off. The configuration includes a signal generator that continuously generates a valve drive signal when the valve is turned OFF, and a valve mechanism that gradually increases or decreases the opening depending on the valve drive signal. If you set a timer to start the pine surge device, it will start pine surge at a low pressure and increase the pine surge pressure to the rated pressure over time, allowing you to wake up refreshed. If you set the timer to stop at bedtime, it will gradually reduce the pine surge pressure, allowing you to have a restful sleep, making the pine surge operation more comfortable than conventional devices. It can be further improved.
