Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention applies a massage action to a human body lying on a bedclothes by sending compressed air from an air compressor through a distribution valve to a plurality of air bags arranged on the top surface of the bedclothes. It is about an air massager to give.

[0002]

2. Description of the Related Art FIGS. 4 to 8 show an example of a conventional air massager. In FIG. 4, reference numeral 1 (see FIG. 4) is a control box of the air massager. Air compressor 2, as shown,
The distribution valve 3 and its driving motor 4 are stored. Reference numeral 5 in the drawing denotes an air supply passage (pipe) from the air compressor 2 to the distribution valve 3.

Further, 6 in FIG. 4 is a power plug connected to the control box 1, 7 is an operation panel as shown in detail in FIG. 5, 8 is a power switch, 9 is an operation indicator light, 10 is a start button, and 11 is A stop button, 12 is a time setting button, 13 is its display window, 14 is a strength selection button, 15 is a strength display indicator, 16 is an air hose pulled out from the distribution valve 3 in the control box 1, and in this case the distribution valve Three
Since there are four discharge ports a, b, c, d as shown in FIG. 8, four air hoses 16 are connected to each discharge port.

Further, four air bladders 17 each having a rectangular plane shape are connected to the four air hoses 16, and these air bladders 17 are, as shown in FIGS. 6 and 7, a mattress and a mattress. The bedding 18 such as the above is arranged in parallel on the upper surface. In addition, 18a is a core material of the bedding 18 and 18b is a cover.

To use this air massager, after a person lies on the bedclothing 18 and turns on the power switch 8 of the control box 1, the time setting button 12 and the strength selection button 14 are set to desired conditions. When the start button is pressed, the air compressor 2 operates to send compressed air to the air bags 17 in sequence through the pipe 5 and the distribution valve 3. Therefore, the air bag 17 is inflated in sequence, so that a massage effect can be given to the human body lying on it.

[0006]

In the air massager described above, the compressed air generated by the rotation of the air compressor 2 is sent to each air bag 17 through the distribution valve 3 in order, and from each air bag 17 again. Since the compressed air is discharged in sequence, there is a problem that noise is generated and it is noisy in use. In FIG. 9, the noise level is measured at a position 1 m away from the control box 1 with the elapsed time on the abscissa.

[0007]

In order to solve the above problems, in the present invention, compressed air is sent from an air compressor to a plurality of air bags arranged on the upper surface of a bedclothes through a distribution valve. In the device described above, an air massager is configured by providing a silencer having an expansion void in the air supply passage from the air compressor to the distribution valve.

[0008]

According to the present invention, as described above, in the air massager in which compressed air is sent from the air compressor to the plurality of air bags arranged on the upper surface of the bedclothes through the distribution valve, Since a muffler having an expansion space was provided in the air supply passage to the distribution valve, the whistle blow, sigh, and poppy sounds generated near the air compressor, the distribution valve, and the suction and discharge ports of each air bag. It is possible to remarkably reduce the noise level.

[0009]

Embodiments of the present invention will be described below with reference to FIGS. In the figure, the same symbols as the above-mentioned symbols indicate the same items. That is, 2 is an air compressor, 3 is a distribution valve, 4 is a motor, 5 is an air supply passage (pipe) from the air compressor 2 to the distribution valve 3, 16 is an air hose connected to the distribution valve 3, and 17 is each air hose 16. Air bag to connect,
18 is bedding.

In this embodiment, a silencer 19 having an expansion space is provided in the air supply passage 5 from the air compressor 2 to the distribution valve 3. Figure 2 shows a silencer with a hollow cylindrical shape 19
Fig. 19a is a cross-sectional view of Fig. 19a showing the expansion void. See also FIG.
FIG. 7 is a cross-sectional view of a muffler 19 having a hollow sphere shape according to another embodiment, and 19a is its expansion void.

[0011]

According to the present invention, as described above, the air massager is configured so that the compressed air is sent from the air compressor 2 through the distribution valve 3 to the plurality of air bags 17 arranged on the upper surface of the bed linen 18. In the above, since the muffler 19 having the expansion space 19a is provided in the air supply passage 5 from the air compressor 2 to the distribution valve 3, the intake and discharge of the air compressor 2, the distribution valve 3, and the air bags 17 are performed. The effect that the noise level such as the whistle blowing sound, the breathing sound, and the popping sound generated near the exit can be remarkably reduced can be obtained.

FIG. 10 shows the noise level of the air massager of the present invention constructed as described above, measured at a position 1 m away from the control box 1 with the elapsed time as the abscissa. Comparing FIG. 9 which is the measured value of the noise level of the conventional device and FIG. 10 which is the measured value of the noise level of the air massager of the present invention, the maximum value of the noise level of the conventional device is about 50 dB. On the other hand, the maximum value of the noise level of the air massager of the present invention is about 35 dB, which is extremely low.
