Hereinafter, a gas massage machine according to an embodiment of the present invention will be described with reference to the accompanying drawings. However, the embodiments shown below are merely examples, and the gas massage machine of the present invention is not limited to the following examples.

1 to 15 show a gas massage machine 1 according to a first embodiment of the present invention. The gas massage machine 1 of this embodiment is a device that massages the body of a user using high-pressure gas. The gas massage machine 1 performs massages such as "massaging" the body of the user for the purpose of improving the body condition of the user, such as improving the stagnation of the veins and lymph nodes of the user and promoting their flow. It is used to stimulate the body of the person being treated. Here, in this specification, "high pressure gas" refers to a gas having a pressure higher than atmospheric pressure. In this embodiment, the gas is air for convenience. However, the gas is not particularly limited, and may be inert gases such as He (helium) and N ₂ (nitrogen), and other gases such as O ₂ (oxygen).

The gas massage machine 1 includes a massage tool 2 and a gas supply/discharge system 3, as shown in FIG.

The massage tool 2 is an instrument that is worn on the body of a user in order to massage the body of the user. The massage tool 2 is fluidly connected to the gas supply and exhaust system 3 via a hose H and a connector C, as shown in FIG. The massage tool 2 receives high-pressure gas from the gas supply/discharge system 3 to expand, and the high-pressure gas is discharged via the gas supply/discharge system 3 to contract. The massage tool 2 compresses the body by expanding, and releases the pressure from the body by contracting. The massage tool 2 massages the body of the user by repeatedly compressing and releasing the pressure on the body.

2A and 2B show the massage tool 2 used in this embodiment, and FIG. 2C shows a part of the massage tool 2 in more detail. 2D to 2F are cross-sectional views taken along the IID-IID line, the IIE-IIE line, and the IIF-IIF line in FIG. 2A, respectively. In this embodiment, as shown in FIGS. 2A and 2B, the massage tool 2 is worn so as to surround the body B of the user, applies pressure to the body B from around the body B, and then releases the pressure. configured to release. Specifically, the massage tool 2 includes a first massage tool 21 that is attached to the crotch of the body B, and a second massage tool 22 that is attached to the crotch of the body B. and the second massage tool 22 are provided so as to be removable from each other. In this way, by configuring the massage tool 2 by the first massage tool 21 and the second massage tool 22 that are removable from each other, it becomes easier to attach the massage tool 2 to the body B. Moreover, it becomes easier to wear the massage tool 2 by changing it from side to side. In FIGS. 2A and 2B, the first massage tool 21 has a boot shape so as to be worn around one leg of the body B, and the second massage tool 22 has a boot shape so as to be worn around one leg of the body B. It has a shorts shape so that it can be worn with. However, the massage tool 2 is not limited to the two-part boot shape and shorts shape as illustrated. For example, in order to massage the entire lower body of the body B, the massage tool 2 may have the shape of pants that are integrated into both the left and right legs and around the waist, or the massage tool 2 may have the shape of pants that are integrated for both the left and right legs and around the waist, or it may massage the entire lower body of the body B. For massaging, it may have a whole-body suit shape that is integrated for the left and right legs, the waist, and the upper body.

The massage tool 2 has a plurality of gas chambers 211 to 218, 221 to 228, which expand by receiving high pressure gas and contract by discharging the high pressure gas. The massage tool 2 further includes a cover 20 that covers the plurality of gas chambers 211-218, 221-228. As shown in FIGS. 2A and 2B, the massage tool 2 is connected to the gas supply and discharge system 3 by fluidly connecting the gas chambers 211 to 218 and 221 to 228 to the gas supply and discharge system 3 (see FIG. 1). Fluid connected. Furthermore, the massage tool 2 is configured to expand and contract as each of the gas chambers 211 to 218 and 221 to 228 expands and contracts. By providing a plurality of gas chambers 211 to 218 and 221 to 228, the massage tool 2 can expand and contract at each corresponding location.

The massage tool 2 includes a plurality of gas chambers 211 to 218, 221 to 228, including leg gas chambers 211 to 218, 221, a groin gas chamber 222, and a gas chamber distal to the leg gas chambers 211 to 218, 221. The leg gas chambers 223, 225, 227 have proximal abdominal gas chambers 224, 226, 228 proximal to the leg gas chambers 211-218, 221. Each of the leg gas chambers 211 to 218, 221, the distal flank gas chambers 223, 225, 227, and the proximal flank gas chambers 224, 226, 228 is constituted by a plurality of gas chambers in this embodiment. However, it may also consist of a single gas chamber. In this embodiment, the distal leg gas chambers 211 to 218 of the leg gas chambers 211 to 218 and 221 are provided in the first massage tool 21. Of the leg gas chambers 211 to 218, 221, the proximal leg gas chamber 221, the groin gas chamber 222, the distal abdominal gas chamber 223, 225, 227, and the proximal abdominal gas chamber 224, 226, 228 is provided on the second massage tool 22.

Each of the plurality of gas chambers 211 to 218 and 221 to 228 is a bag-shaped member, and is provided so as to correspond to each part of the body B to be massaged. At least some of the gas chambers 211 to 218 and 221 to 228 are provided so as to surround the body B in the circumferential direction CD of the body B. In this embodiment, at least some of the gas chambers 211 to 218 and 221 to 228 are provided so as to surround a predetermined portion of the lower body of the body B in the circumferential direction CD of the body B. Here, in this specification, "lower body" refers to the part of body B below the waist, and "upper body" refers to the part of body B above the waist. The arrangement and number of the gas chambers 211 to 218 and 221 to 228 can be set as appropriate depending on the part of the body B to be massaged and the control mode of the massage to be performed. For example, when performing a massage in a wave mode to be described later. In order to achieve this, it is sufficient to provide at least four gas chambers (for example, gas chambers 221 to 224) that are consecutively provided as gas chambers. The gas chambers 211 to 218 and 221 to 228 are formed in a size such that they can expand to press the corresponding part of the body B, and contract to release the pressure on the corresponding part of the body B. The shapes and sizes of the gas chambers 211 to 218 and 221 to 228 can be determined as appropriate depending on the part of the body B to which they are attached. The material of the gas chambers 211-218, 221-228 is not particularly limited as long as it has airtightness to store high-pressure gas and can be deformed by receiving and discharging high-pressure gas, and is formed of, for example, a resin material. The gas chambers 211 to 218 and 221 to 228 may be fluidly connected to each other in the order in which they are expanded. In this way, if high-pressure gas is supplied to the gas chamber to be expanded first, the high-pressure gas is supplied to the next gas chamber to be expanded.

In this embodiment, the plurality of gas chambers 211 to 218, 221 to 228 are configured to be expandable by releasing fasteners 21A to 23A for opening and closing the cover 20. When the fasteners 21A to 23A are fastened, at least some of the gas chambers 211 to 218 and 221 to 228 that are the same (see gas chamber 215 in FIG. 2D) or adjacent gas chambers (see FIG. 2E) The gas chambers 222-224 (see gas chambers 227, 228 in FIG. 2F) overlap in the circumferential direction CD of the body B. When the gas chambers 211 to 218 and 221 to 228 overlap, the end regions of the gas chambers 211 to 218 and 221 to 228 overlap each other within a predetermined length range from the end in the circumferential direction CD. 218, 221 to 228 are arranged without gaps in the circumferential direction CD. Therefore, when the gas chambers 211 to 218 and 221 to 228 are expanded, they can uniformly compress the body B regardless of the installation positions of the fasteners 21A to 23A. In order to enable such overlap, in this embodiment, the gas chambers 211 to 218 and 221 to 228 are formed to be longer than the cover 20 in the circumferential direction CD. Normally, when a fastener is provided on a massage tool, a gas chamber is not provided in the area where the fastener is installed so as not to become an obstacle when the fastener is fastened, so a gap is created between the gas chambers. Therefore, the part of the body B that does not face the gas chamber but faces the fastener is not compressed even when the gas chamber expands, resulting in uneven pressure on the body B by the massage tool. However, in this embodiment, the gas chambers 211 to 218 and 221 to 228 overlap each other in the circumferential direction CD, so that uneven pressure on the body B does not occur. The positions where the ends of the gas chambers 211 to 218 and 221 to 228 overlap may be in the vicinity of the fasteners 21A to 23A, as shown in FIGS. 2D and 2E, or in the vicinity of the fasteners 21A to 23A, as shown in FIG. 2F. The position may be spaced apart from the tools 22A and 23A. However, as on one side (dorsal side) of body B in FIG. 2F, the gas chambers 211 to 218 and 221 to 228 (only gas chambers 227 and 228 are shown in FIG. 2F) do not necessarily overlap each other. Perimeter adjustment mechanisms 21B and 22B that adjust the length of the massage tool 2 in the circumferential direction CD without needing to overlap and usually do not overlap (in FIG. 2F, only the peripheral length adjustment mechanism 22B is shown). After the length of the massage tool 2 in the circumferential direction CD is adjusted using the above method, the overlap may be made.

The leg gas chambers 211 to 218, 221 are gas chambers that compress one leg of the body B. The leg gas chambers 211 to 218, 221 are provided in the massage tool 2 at a location corresponding to one leg of the body B. In this embodiment, the leg gas chambers 211 to 218, 221 are provided to correspond to the entirety of one leg, as shown in FIGS. 2A and 2B. However, in particular, lymphedema may occur in only one leg of the patient rather than both legs, or may occur only at the base of one leg. In some cases, it may be sufficient to provide a leg gas chamber only in one leg or in a part of one leg, depending on the location of the occurrence. In this embodiment, as shown in FIG. 2D, the leg gas chambers 211 to 218, 221 (only the fifth distal leg gas chamber 215 is shown in FIG. 2D) are connected to the first distal leg gas chamber 215, which will be described later. When the first fastener 21A is fastened, one end side and the other end side of the same gas chamber overlap in the vicinity of the first fastener 21A. The leg gas chambers 211-218, 221 may be provided throughout both legs in order to massage both legs in their entirety. In this embodiment, the leg gas chambers 211 to 218, 221 are distal leg gas chambers 211 to 218 provided at a site corresponding to the distal side of one leg of the body B, and The proximal leg gas chamber 221 is provided at a portion corresponding to the proximal part of the leg. The distal leg gas chambers 211 to 218 are preferably provided adjacent to the proximal leg gas chamber 221 in order to increase the effect of continuous upward flow of lymph fluid. However, the positions of the distal leg gas chambers 211 to 218 and the proximal leg gas chamber 221 are such that the distal leg gas chambers 211 to 218 are located further from the torso of body B than the proximal leg gas chamber 221. As long as it is on the side, there are no particular limitations. For example, distal leg gas chambers 211-218 may be spaced apart from proximal leg gas chamber 221. Further, the number of gas chambers each of the distal leg gas chambers 211 to 218 and the proximal leg gas chamber 221 has is not particularly limited as long as it is one or more. In the present embodiment, the distal leg gas chambers 211 to 218 are arranged in a direction from a region corresponding to the tip of one leg to a region corresponding to the center of the upper thigh. It has eight gas chambers in order from the eighth distal leg gas chamber 218 to the eighth distal leg gas chamber 218 . The first distal leg gas chamber 211 to the eighth distal leg gas chamber 218 are each provided so as to surround one leg in the circumferential direction CD of the body B. In this embodiment, the proximal leg gas chambers 221 have one gas chamber in each region corresponding to the base of the upper thigh of both legs (two gas chambers in total). The proximal leg gas chamber 221 can accommodate two gases by fluidly connecting the two gas chambers to each other or by individually fluidly connecting the two gas chambers to branch hoses branched from one hose H. The high pressure gas is supplied to the chambers at the same time, and the high pressure gas is discharged from the two gas chambers at the same time. However, the proximal leg gas chamber 221 may be provided so as to surround only one leg, or even when provided in both legs, high pressure gas is supplied and discharged independently of each other. It may be configured so that

The groin gas chamber 222 is a gas chamber that presses the groin region of the body B. The groin gas chamber 222 is provided in the massage tool 2 at a location corresponding to the groin of the body B. Note that in this specification, the term "groin area" refers to the area between one leg and the other leg at a branching portion where a pair of legs diverge from the torso. In this embodiment, the groin gas chamber 222 corresponds not only to a region corresponding to the groin region, but also to a region corresponding to the lower abdomen on the ventral side of body B, and to a central region of the buttocks on the dorsal side of body B. There are also areas where you can In this specification, when the abdomen of body B is divided into three parts, upper and lower, the lower part of the three parts is called the "lower abdomen," the middle part is called the "middle abdomen," and the upper part is called the "lower abdomen." It's called the "upper abdomen." For example, the mid-abdomen is the part of body B near the navel, the lower abdomen is the part of body B below the navel, and the upper abdomen is the part of body B above the navel. The groin gas chamber 222 is provided so as to extend from a region corresponding to the lower abdomen, through a region corresponding to the groin region, to a region corresponding to the central region of the buttocks. Especially in the case of women, lymph fluid may accumulate in the groin area near the vulva due to lymphedema, so by expanding the groin gas chamber 222 and compressing the groin area, lymph fluid may accumulate in the vulva. In addition to preventing this, it can also promote the flow of lymph fluid. Further, by expanding the groin gas chamber 222 and compressing the lower abdomen, it is possible to prevent lymph fluid from stagnation in the lower abdomen and to promote the flow of lymph fluid. Furthermore, by expanding the groin gas chamber 222 and compressing the center of the buttocks, it is possible to promote the flow of lymph fluid on the back side of the body B as well. In this embodiment, as shown in FIG. 2E, the crotch gas chamber 222 is connected to the second distal fastener 22A and the second proximal fastener 23A, which will be described later. In the vicinity of the distal fastener 22A and the second proximal fastener 23A, an end of the first distal abdominal gas chamber 223 and an end of the first proximal abdominal gas chamber 224 are adjacent to each other. overlap.

When the lymph fluid in the legs flows upward due to the expansion of the leg gas chambers 211 to 218, 221, if the groin gas chamber 222 is expanded, the groin region is compressed and the flow of lymph fluid to the groin region is prevented. Ru. As a result, lymph fluid flows smoothly above body B. The leg gas chambers 211-218, 221 and the groin gas chamber 222 are then followed by the distal abdominal gas chambers 223, 225, 227 and the proximal abdominal gas chambers 224, 226, 228, as detailed below. By sequentially expanding the , lymph fluid can flow smoothly upwards in the body B.

The gas supply and exhaust system 3 supplies high-pressure gas to the plurality of gas chambers 211-218, 221-228, and discharges the high-pressure gas from the plurality of gas chambers 211-218, 221-228. In this embodiment, the gas supply and discharge system 3 controls the supply and discharge of high-pressure gas using a solenoid valve, as shown in FIG. The gas supply/discharge system 3 includes a solenoid valve unit 5 fluidly connected to the gas chambers 211 to 218, 221 to 228 (see FIGS. 2A and 2B) of the massage tool 2, and a gas supply unit 5 fluidly connected to the solenoid valve unit 5. A control device 6 that controls a device 4 and a solenoid valve unit 5 is provided. However, the gas supply and exhaust system 3 only needs to be configured to supply high pressure gas to the gas chambers 211 to 218 and 221 to 228 and to discharge high pressure gas from the gas chambers 211 to 218 and 221 to 228. For this purpose, other actuators such as motorized valves may control the supply and discharge of high pressure gas. Furthermore, as described above, when the order in which the gas chambers 211 to 218 and 221 to 228 are inflated is determined by the fluid connection between the gas chambers in which the order in which they are to be expanded is determined, the gas supply and exhaust system 3 The electromagnetic valve unit 5 and the control device 6 may not necessarily be provided.

Further, the housing 3a is provided with a pressing member 71 that is pressed by the user in an emergency such as a power outage. The pressing member 71 constitutes a part of the emergency stop structure of the gas massage machine 1. Details of the pressing member 71 and the connector C that constitute a part of the emergency stop structure will be described later.

The gas supply device 4 is a device that supplies high pressure gas to the solenoid valve unit 5. The gas supply device 4 is fluidly connected to the solenoid valve unit 5 . The gas supply device 4 is not particularly limited as long as it can supply high-pressure gas to the solenoid valve unit 5, and may be, for example, a pump that delivers high-pressure gas or a cylinder that spouts high-pressure gas just by opening a valve. It can be configured by In this embodiment, the gas supply device 4 is an air pump that delivers high-pressure air from the viewpoint of convenience. The gas supply device 4 may be provided separately from the gas supply/discharge system 3 and outside the housing 3a.

The solenoid valve unit 5 supplies high pressure gas to the gas chambers 211 to 218 and 221 to 228 (see FIGS. 2A and 2B) of the massage tool 2, and removes the high pressure gas from the gas chambers 211 to 218 and 221 to 228 of the massage tool 2. This is a device that switches the flow path of high-pressure gas to discharge the gas. In this embodiment, the gas supply and exhaust system 3 includes two electromagnetic valve units 51 and 52, as shown in FIGS. 3 and 6A. However, the number of solenoid valve units can be determined as appropriate depending on the number of gas chambers to be fluidly connected and the control mode for massaging body B, and may be one, or three or more. There may be.

As schematically shown in FIG. 4, the electromagnetic valve unit 5 includes an intermediate chamber R that accommodates high-pressure gas to be supplied to gas chambers 211 to 218, 221 to 228 (see FIGS. 2A and 2B), and an intermediate chamber R. a connection port P0 that is connected to the intermediate chamber R and fluidly connects the intermediate chamber R and the gas chambers 211 to 218, 221 to 228; and an air supply port that is connected to the intermediate chamber R and fluidly connects the intermediate chamber R and the gas supply device 4. P1, and an exhaust port P2 connected to the intermediate chamber R and discharging high pressure gas from the intermediate chamber R. The solenoid valve unit 5 includes a connection solenoid valve V0 for opening and closing the connection port P0, and an exhaust solenoid valve V2 for opening and closing the exhaust port P2. Further, the solenoid valve unit 5 may further include an air supply solenoid valve V1 for opening and closing the air supply port P1.

In this embodiment, in the solenoid valve unit 5, the air supply port P1 is opened by the air supply solenoid valve V1, and the exhaust port P2 is closed by the exhaust solenoid valve V2. By supplying high pressure gas to and opening the connection port P0 by the connection solenoid valve V0, the high pressure gas in the intermediate chamber R is supplied to the gas chambers 211 to 218, 221 to 228 (see FIGS. 2A and 2B). The gas chambers 211 to 218 and 221 to 228 are brought into a high pressure state. After the high pressure gas is supplied to the gas chambers 211 to 218 and 221 to 228, when the connection port P0 is kept closed by the connection solenoid valve V0, the pressure in the gas chambers 211 to 218 and 221 to 228 decreases. is held at high pressure. Further, in this embodiment, when the air supply port P1 is closed by the air supply solenoid valve V1, the exhaust port P2 is opened by the exhaust solenoid valve V2, and the connection port P0 is opened by the connection solenoid valve V0, The high pressure gas in the gas chambers 211-218, 221-228 is exhausted through the intermediate chamber R and the exhaust port P2. However, the air supply solenoid valve V1 for opening and closing the air supply port P1 does not necessarily need to be provided. When the air supply solenoid valve V1 is not present, the exhaust port P2 is closed by the exhaust solenoid valve V2, and when the connection port P0 is opened by the connection solenoid valve V0, the air flows through the air supply port P1 and the intermediate chamber R. High pressure gas is supplied to gas chambers 211-218, 221-228. Furthermore, when the exhaust port P2 is opened by the exhaust solenoid valve V2 and the connection port P0 is opened by the connection solenoid valve V0, high pressure gas is supplied from the air supply port P1, but high pressure gas is not supplied from the exhaust port P2. Since the gas is discharged in the same manner, high-pressure gas is also discharged from the gas chambers 211 to 218 and 221 to 228 to the intermediate chamber R.

In the solenoid valve unit 5, as described above, the connection solenoid valve V0 is a two-way valve having a valve body Vb that opens and closes the connection port P0, and the valve body Vb is in the closed state that closes the connection port P0. and an open state in which the connection port P0 is opened. Therefore, the air pressure in the gas chamber can be maintained at a high pressure without continuing to supply high-pressure gas to the gas chamber. Moreover, in the electromagnetic valve unit 5, the valve body Vb does not move outside the intermediate chamber R to open and close the connection port P0 on the outer surface of the intermediate chamber R, but moves inside the intermediate chamber R, The connection port P0 is opened and closed on the inner surface of the intermediate chamber R. Therefore, the electromagnetic valve unit 5 can be made compact by the length of the stroke of the opening/closing operation of the valve body Vb. In addition, in this embodiment, the air supply solenoid valve V1 and the exhaust solenoid valve V2 are in a closed state in which the air supply port P1 and the exhaust port P2 are respectively closed, and in a closed state in which the air supply port P1 and the exhaust port P2 are respectively opened. It is a two-way valve that switches between an open state and an open state. However, regarding the air supply port P1 and the exhaust port P2, both do not need to be opened or closed at the same time, and one may be closed and the other opened, so the air supply solenoid valve V1 and the exhaust solenoid valve The valve V2 may be constituted by a common three-way valve for switching between fluidly connecting the intermediate chamber R and the air supply port P1 and fluidly connecting the intermediate chamber R and the exhaust port P2.

One solenoid valve unit 5 is not particularly limited, but in this embodiment, as shown in FIG. 4, one solenoid valve unit 5 is composed of a plurality of (two in the illustrated example) solenoid valve blocks 500 having the same structure.

The solenoid valve block 500 includes a connection solenoid valve V0 for opening and closing the connection port P0, and an air supply and exhaust solenoid valve V1 (V2) for opening and closing the air supply and exhaust port P1 (P2). However, there may be a solenoid valve block 500 that does not include the supply/exhaust port P1 (P2) and the supply/exhaust port P1 (P2), and in this case, another solenoid valve block that is fluidly connected to the solenoid valve block 500 is provided. , an air supply/exhaust port P1 (P2), and an air supply/exhaust solenoid valve V1 (V2). Moreover, although the electromagnetic valve block 500 has only one intermediate chamber Ra in FIG. 4, it may have a plurality of intermediate chambers Ra. Further, in FIG. 4, the intermediate chamber Ra is fluidly connected between the plurality of electromagnetic valve blocks 500, but only the intermediate chamber Ra of a single electromagnetic valve block 500 may be used.

In this embodiment, as shown in FIG. 4, the open port P3 of one solenoid valve block 500 (lower side in FIG. 4) and the open port P3 of the other solenoid valve block 500 (upper side in FIG. 4) are connected to each other. By being fluidly connected via a common tank 53, which will be described later, both electromagnetic valve blocks 500, 500 are fluidly connected to each other to form one electromagnetic valve unit 5. At this time, the intermediate chamber Ra of one solenoid valve block 500 and the intermediate chamber Ra of the other solenoid valve block 500 are fluidly connected via both open ports P3, P3 to the intermediate chamber of one solenoid valve unit 5. form R. Further, the supply/exhaust port P1 of one solenoid valve block 500 constitutes the supply/exhaust port P1 of one solenoid valve unit 5, and the supply/exhaust port P2 of the other solenoid valve block 500 constitutes the supply/exhaust port P1 of one solenoid valve unit 5. This constitutes an exhaust port P2. Connection ports P0, P0 of both electromagnetic valve blocks 500, 500 constitute connection port P0 of one electromagnetic valve unit 5. As described above, one solenoid valve unit 5 supplies high pressure gas to the gas chambers 211 to 218 and 221 to 228 by opening and closing the air supply port P1, exhaust port P2, and connection port P0. , the high-pressure gas flow path is switched so that the high-pressure gas is discharged from the gas chambers 211-218, 221-228. However, one solenoid valve unit 5 may be formed of only one solenoid valve block 500. At this time, the intermediate chamber Ra of one electromagnetic valve block 500 constitutes the intermediate chamber R of one electromagnetic valve unit 5. Also, at this time, the open port P3 of one solenoid valve block 500 is fluidly connected to the gas supply device 4, thereby configuring the air supply port P3 of one solenoid valve unit 5, and the one solenoid valve block 500 The supply/exhaust port P1 (P2) constitutes the exhaust port P1 (P2) of one electromagnetic valve unit 5. In this case, one solenoid valve unit 5 supplies high pressure gas to the gas chambers 211 to 218 and 221 to 228 by opening and closing the exhaust port P1 (P2) and the connection port P0. , 221 to 228, the flow path of the high pressure gas is switched.

The electromagnetic valve block 500 includes a block main body MB provided with ports P0, P1 (P2), P3 and an intermediate chamber Ra, and electromagnetic valves V0, V1 (V2) attached to the block main body MB.

The block body MB is interposed between a first body member 501 and a second body member 502, and between the first body member 501 and the second body member 502, as shown in FIGS. 5A and 5B. A seal member 503 is provided. The block body MB is formed by coupling a first body member 501 and a second body member 502 to each other via a sealing member 503 by known coupling means (not shown) (fitting, screwing, etc.). . The first body member 501 and the second body member 502 are configured to form an intermediate chamber Ra and flow paths F0 and F1, which will be described later, inside the block body MB when coupled to each other. The first main body member 501 and the second main body member 502 only need to have such rigidity that deformation can be suppressed against the pressing force caused by high-pressure gas or the pressing force caused by opening and closing of ports by electromagnetic valves. Although not particularly limited, it can be formed of a rigid material such as a resin material, a ceramic material, or a metal material. Further, the sealing member 503 is not particularly limited as long as it can provide a predetermined airtightness to the intermediate chamber Ra and the flow paths F0 and F1 formed inside the block main body MB. Packing can be used.

As shown in FIGS. 5A and 5B, the first main body member 501 is formed into a substantially rectangular plate shape having a first surface 501a on one side and a second surface 501b on the other side.

The first surface 501a of the first body member 501 includes a connection port P0 that projects substantially perpendicularly to the first surface 501a and an air supply/exhaust port P1 (P2) that projects substantially parallel to the first surface 501a. It is provided. Further, the second surface 501b of the first main body member 501 is provided with a recess D0 for forming a flow path F0 extending from the connection port P0 to the intermediate chamber Ra. When the first body member 501 and the second body member 502 are coupled to each other, the recess D0 is sealed by the second body member 502, and a flow path F0 is formed.

As shown in FIGS. 5A and 5B, the second main body member 502 is formed into a substantially rectangular plate shape having a first surface 502a on one side and a second surface 502b on the other side. The second surface 502b of the second main body member 502 is provided with a solenoid valve support portion 502c that protrudes from the second surface 502b and supports the solenoid valves V0, V1 (V2). The second body member 502 is coupled to the first body member 501 such that the first surface 502a faces the second surface 501b of the first body member 501. The first surface 502a of the second main body member 502 has a recess D1 for forming a flow path F1 extending from the air supply/exhaust port P1 (P2) to the intermediate chamber Ra, and a recess D2 for forming the intermediate chamber Ra. An open port P3 is provided on the second surface 502b of the second main body member 502, passing through the bottom of the recess D2. By coupling the first body member 501 and the second body member 502 to each other, the recess D1 is sealed to form the flow path F1, and the recess D2 is sealed to form the intermediate chamber Ra. . Note that the flow path F1 is included in the intermediate chamber Ra.

As shown in FIGS. 5A and 5B, the second main body member 502 further includes a recess D3 for inserting the connection solenoid valve V0 and an air supply/exhaust solenoid valve V1 (V2) on the second surface 502b. A recess D4 for insertion is provided. The recesses D3 and D4 communicate with the recesses D1 and D2 and constitute a part of the intermediate chamber Ra. The second main body member 502 has the connection solenoid valve V0 and the supply/exhaust solenoid valve V1 (V2) inserted into the recesses D3 and D4 from the second surface 502b side. V1 (V2) is attached. At this time, the intermediate chamber Ra is formed by maintaining communication with the recesses D1 and D2 while the recesses D3 and D4 are sealed from the second surface 502b side. The second body member 502 further includes a through hole T0 that penetrates from the first surface 502a toward the second surface 502b at the bottom of the recess D3 and fluidically connects the flow path F0 and the intermediate chamber Ra; A through hole T1 is provided at the bottom, penetrating from the first surface 502a toward the second surface 502b, and communicating between the intermediate chamber Ra and the air supply/exhaust port P1 (P2).

As described above, the connection port P0 and the air supply/exhaust port P1 (P2) are connected to the intermediate chamber Ra via the flow paths F0 and F1, respectively. Therefore, by freely arranging the flow paths F0 and F1, the connection port P0 and the supply/exhaust port P1 (P2) can be freely arranged regardless of the arrangement of the intermediate chamber Ra and the solenoid valves V0 and V1 (V2). I can do it. In this embodiment, one solenoid valve block 500 is provided with four connection ports P0, but when connecting to the gas chambers 211 to 218, 221 to 228 (see FIGS. 2A and 2B) of the massage tool 2, In order to arrange the hoses H in a concentrated manner (see FIG. 3), the four connection ports P0 can be arranged closely. In particular, by arranging it locally on one side of the first surface 501a of the first main body member 501, when it is arranged adjacent to another electromagnetic valve block 500, the connection port P0 of another electromagnetic valve block 500 (See FIG. 6A).

The electromagnetic valves V0 and V1 (V2) are electrically driven valves that open and close the ports P0 and P1 (P2). As shown in FIGS. 5A and 5B, in this embodiment, electromagnetic valves V0 and V1 (V2) are attached to the block body MB corresponding to ports P0 and P1 (P2) that need to be opened and closed. More specifically, the solenoid valves V0, V1 (V2) are inserted into recesses D3, D4 provided in the second surface 502b of the second body member 502 in order to open and close the ports P0, P1 (P2). and attached to the second body member 502. In this embodiment, the open port P3 is not provided with a solenoid valve and is always open. As described above, the open port P3 functions as an intermediate port when fluidly connecting the two electromagnetic valve blocks 500, 500 to each other. Further, when the solenoid valve unit 5 is configured with one solenoid valve block 500, the open port P3 functions as an air supply port for connection to the gas supply device 4. However, even when the solenoid valve unit 5 is configured with one solenoid valve block 500, a solenoid valve may be provided corresponding to the open port P3.

The connection solenoid valve V0 and the supply/exhaust solenoid valve V1 (V2) are not particularly limited, but the same solenoid valve can be used for both. Although the connection solenoid valve V0 will be described below, other solenoid valves have similar configurations. As shown in FIG. 5B, the solenoid valve V0 includes a valve seat Va, a valve body Vb, an electromagnet Vc, and a biasing body Vd. As described above, the solenoid valve V0 constitutes a two-way valve.

The valve seat Va is provided adjacent to the flow path (through hole T0) that is to be opened and closed, and is a part against which the valve body Vb comes into contact. The valve seat Va is formed so that the flow path (through hole T0) is closed when the valve body Vb comes into contact with the valve seat Va. In this embodiment, as shown in FIG. 5B, the valve seat Va is inserted into the recess D3 provided in the second surface 502b of the second main body member 502 from the periphery of the through hole T0 at the bottom of the recess D3. It is formed as a substantially cylindrical portion that protrudes along the direction in which the hole T0 extends.

The valve body Vb is a member that opens and closes the flow path (through hole T0) that is to be opened and closed in cooperation with the valve seat Va. The valve body Vb is configured to be movable between a closed position where it contacts the valve seat Va and closes the flow path, and an open position where it separates from the valve seat Va and opens the flow path. In this embodiment, the valve body Vb is formed as a rod-shaped member extending in one direction, and is configured to be movable along the direction in which the rod-shaped member extends by the electromagnetic force of the electromagnet Vc and the urging force of the urging body Vd. The valve body Vb contains a magnetic material such as iron so as to be driven by the electromagnetic force of the electromagnet Vc. The tip of the valve body Vb that contacts the valve seat Va is preferably made of an elastic body such as rubber. In this case, when the tip of the valve body Vb comes into contact with the valve seat Va, the tip of the valve body Vb can deform to follow the shape of the valve seat Va, so the flow path can be maintained in a highly airtight state. (Through hole T0) can be closed.

The electromagnet Vc applies electromagnetic force to the valve body Vb by being supplied with electric power. In this embodiment, the electromagnet Vc is configured to be able to apply an electromagnetic force to the valve body Vb to urge the valve body Vb in a direction away from the valve seat Va when electric power is supplied. However, the electromagnet Vc may be configured to be able to apply an electromagnetic force to the valve body Vb to urge the valve body Vb toward the valve seat Va when electric power is supplied. The electromagnet Vc is not particularly limited, but from the viewpoint of structural simplicity, a cylindrical solenoid coil that accommodates the valve body Vb therein can be employed.

The biasing body Vd biases the valve body Vb in a predetermined direction to maintain the open or closed state of the solenoid valve V0. In this embodiment, the biasing body Vd is configured to bias the valve body Vb toward the valve seat Va in order to maintain the closed state of the solenoid valve V0. In this case, the solenoid valve V0 can constitute a normally closed valve that remains closed when power is not supplied. However, the biasing body Vd may be configured to bias the valve body Vb in a direction away from the valve seat Va in order to maintain the open state of the electromagnetic valve V0. In this case, the electromagnetic valve V0 can constitute a normally open valve that remains open when power is not supplied. The biasing body Vd is not particularly limited as long as it can bias the valve body Vb in a predetermined direction, and a known spring or the like can be used.

In this embodiment, the solenoid valve unit 5 is configured by combining a plurality of solenoid valve blocks 500 configured as described above. 6A to 6D show a solenoid valve unit 5 configured by combining a plurality of solenoid valve blocks 500. In this embodiment, the gas supply/exhaust system 3 includes a first solenoid valve unit 51 and a second solenoid valve unit 52 as the solenoid valve unit 5, as shown in the figure. The first solenoid valve unit 51 and the second solenoid valve unit 52 each include a plurality of (two in the illustrated example) solenoid valve blocks 500. The four solenoid valve blocks 500 are arranged such that the two solenoid valve blocks 500 of the second solenoid valve unit 52 are arranged adjacent to each other, and the two solenoid valve blocks 500 of the first solenoid valve unit 51 are arranged adjacent to each other. The two solenoid valve blocks 52 are arranged in parallel so as to sandwich the two solenoid valve blocks 500 between them. The four electromagnetic valve blocks 500 are arranged in a direction rotated by 180° between adjacent electromagnetic blocks 500 when viewed from the front.

In this embodiment, the solenoid valve unit 5 includes a common tank 53 to which the first and second solenoid valve units 51, 52 are fluidly connected, as shown in FIGS. 6A to 6D. The first and second solenoid valve units 51 , 52 are in this embodiment fluidly connected to the gas supply device 4 via a common tank 53 . However, the first and second electromagnetic valve units 51 and 52 may be directly fluidly connected to the gas supply device 4 without going through the common tank 53. Details of the common tank 53 will be described later.

As shown in FIGS. 6A to 6D, the first solenoid valve unit 51 has an intermediate chamber R1, first to eighth connection ports P11 to P18, an air supply port P10, an exhaust port P19, and an It includes first to eighth connection solenoid valves V11 to V18, an air supply solenoid valve V10, and an exhaust solenoid valve V19. The second solenoid valve unit 52 also connects the intermediate chamber R2, the first to eighth connection ports P21 to P28, the air supply port P20, the exhaust port P29, and the first to eighth connection solenoid valves. V21 to V28, an air supply solenoid valve V20, and an exhaust solenoid valve V29.

The intermediate chambers R1 and R2 are portions that store high-pressure gas to be supplied to the gas chambers 211-218 and 221-228. Each of the intermediate chambers R1, R2 is connected to a common tank 53 in fluid communication with the solenoid valve block 500 (specifically, the second chamber shown in FIG. 6D), as described above. It is formed by being fluidly connected via an in-tank flow path 534b and a third in-tank flow path 534c). However, each of the intermediate chambers R1 and R2 may be formed by directly fluidly connecting the intermediate chamber Ra of the electromagnetic valve block 500 without using the common tank 53.

The connection ports P11 to P18 and P21 to P28 are ports that fluidically connect the intermediate chambers R1 and R2 to the gas chambers 211 to 218 and 221 to 228 of the massage tool 2. In this embodiment, the connection ports P11 to P18 and P21 to P28 are configured by the connection port P0 in the plurality of electromagnetic valve blocks 500, as described above. In this embodiment, as described above, as a result of densely arranging the connection ports P0 in the solenoid valve block 500, the connection ports P11 to P14 and P21 to P24 are grouped together, and the connection ports P15 to P18 and P25 to P28 are grouped together. As a group, the connection ports P11 to P18 and P21 to P28 are arranged closely. Therefore, the first connector C1 and the second connector C2 (see FIG. 3) are connected to the connection port group of connection ports P11 to P14 and P21 to P24 and the connection port group of connection ports P15 to P18 and P25 to P28. becomes easier.

The air supply ports P10 and P20 are ports that supply high pressure gas to the intermediate chambers R1 and R2. The air supply ports P10, P20 are connected to the intermediate chambers R1, R2 and provide fluid connection between the intermediate chambers R1, R2 and the gas supply device 4. In this embodiment, the air supply ports P10 and P20 are fluidly connected to the gas supply device 4 via the common tank 53 (specifically, the first in-tank flow path 534a shown in FIG. 6D). The air supply ports P10, P20 are configured by the air supply/exhaust port P1 in one of the two electromagnetic valve blocks 500, as described above.

Exhaust ports P19 and P29 are ports that exhaust high pressure gas from intermediate chambers R1 and R2. Exhaust ports P19, P29 are connected to intermediate chambers R1, R2 and provide fluid connection between intermediate chambers R1, R2 and the atmosphere. The exhaust ports P19 and P29 are configured by the supply/exhaust port P2 in one of the two electromagnetic valve blocks 500, as described above.

In this embodiment, the open ports P3, P3 of the two electromagnetic valve blocks 500 constituting the first electromagnetic valve unit 51 become intermediate ports P100, P190 that fluidly connect the two electromagnetic valve blocks 500. Further, in this embodiment, the open ports P3, P3 of the two electromagnetic valve blocks 500 constituting the second electromagnetic valve unit 52 become intermediate ports P200, P290 that fluidly connect the two electromagnetic valve blocks 500.

The connection solenoid valves V11 to V18 and V21 to V28 are solenoid valves that open and close the connection ports P11 to P18 and P21 to P28. The connection solenoid valves V11 to V18 and V21 to V28 are provided in the solenoid valve units 51 and 52 so as to correspond to the connection ports P11 to P18 and P21 to P28. As described above, the connection solenoid valves V11 to V18 and V21 to V28 are in a closed state in which connection ports P11 to P18 and P21 to P28 are closed, and in an open state in which connection ports P11 to P18 and P21 to P28 are opened. It is a two-way valve that switches.

When a three-way valve is provided at a connection port as in the past, the connection port is connected to either an air supply port or an exhaust port. That is, if the connection port is connected to the air supply port, high pressure gas is supplied to the gas chamber, and if the connection port is connected to the exhaust port, high pressure gas is exhausted from the gas chamber. In other words, there is no state in which a connection port is disconnected from any port. Therefore, unless the connection port is connected to the air supply port, high pressure gas cannot be held in the gas chamber. On the other hand, if two-way valves are adopted as the connection solenoid valves V11 to V18 and V21 to V28 as in this embodiment, the corresponding connection ports P11 to P18 and P21 to P28 are closed, respectively, as described above. can do. Thereby, high-pressure gas can be held in the gas chambers 211-218, 221-228 without continuing to supply the high-pressure gas to the gas chambers 211-218, 221-228.

Moreover, one three-way valve requires two ports (an air supply port and an exhaust port) for one connection port. In other words, one three-way valve requires three ports, so if a three-way valve is provided at each connection port, the number of ports increases. For example, when 16 connection ports are provided as shown in FIG. 6A, if each connection port is opened and closed by a three-way valve, the total number of ports becomes 48 (3×16). In this case, the solenoid valve unit requires a space for providing 48 ports, which increases the size of the solenoid valve unit and further complicates the flow path design of the solenoid valve unit. In contrast, a two-way valve requires only one port (supply/exhaust port) for one connection port. For example, when providing 16 connection ports as shown in Figure 4A, if each connection port is opened and closed with a two-way valve, the total number of ports will be 32 (2 x 16) by simple calculation. . Furthermore, in this embodiment, the connection ports P11 to P18, P21 to P28 and the supply/exhaust ports P10, P19, P20, and P29 share intermediate chambers R1 and R2 as spaces for sending and receiving high pressure gas. Therefore, in this embodiment, the total number of ports is 20 (16 (number of connection ports) + 4 (number of supply/exhaust ports)). In this way, in this embodiment, the number of required ports is reduced by using the two-way valve, so the solenoid valve unit 5 is downsized, and the flow path design of the solenoid valve unit 5 is also simplified.

Furthermore, if a two-way valve is used, high-pressure gas can be held in the gas chambers 211-218, 221-228 by closing the connection ports P11-P18, P21-P28, as described above. Utilizing this feature, the solenoid valve unit 5 can also be controlled as follows. When the connecting solenoid valves V11 to V18 and V21 to V28 are switched to the open or closed state, it takes a certain amount of pressure for the air pressure in the gas chambers 211 to 218, 221 to 228 to be the same as the air pressure in the intermediate chambers R1 and R2. It takes time. Therefore, for example, when high-pressure gas is stored in the intermediate chambers R1 and R2 and high-pressure gas is not stored in the gas chambers 211 to 218 and 221 to 228, the connection solenoid valves V11 to V18, V21 to V28 are opened and then closed. Further, for example, when high pressure gas is not stored in the intermediate chambers R1 and R2 but high pressure gas is stored in the gas chambers 211 to 218 and 221 to 228, the connection solenoid valve V1 ～V18, V21～V28 are opened and then closed. In this way, the gas chambers 211 to 218 and 221 to 228 can be maintained at an intermediate level of pressure, which is higher than atmospheric pressure but lower than the pressure of the high pressure gas supplied. Therefore, in this embodiment, the air pressures of the plurality of gas chambers 211 to 218 and 221 to 228 can be freely controlled.

The air supply solenoid valves V10 and V20 are solenoid valves that open and close the air supply ports P10 and P20. Air supply solenoid valves V10 and V20 are provided corresponding to air supply ports P10 and P20. In this embodiment, the air supply solenoid valves V10 and V20 are switched between two states: a closed state in which the air supply ports P10 and P20 are closed, and an open state in which the air supply ports P10 and P20 are opened, as described above. It is a valve. That is, when the air supply solenoid valves V10 and V20 are in the open state, high pressure gas is supplied to the intermediate chambers R1 and R2, and when the air supply solenoid valves V10 and V20 are in the closed state, the high pressure gas is supplied to the intermediate chambers R1 and R2. High pressure gas is not supplied.

The exhaust solenoid valves V19 and V29 are solenoid valves that open and close the exhaust ports P19 and P29. Exhaust solenoid valves V19 and V29 are provided corresponding to exhaust ports P19 and P29. In this embodiment, the exhaust electromagnetic valves V19 and V29 are two-way valves that switch between a closed state in which the exhaust ports P19 and P29 are closed and an open state in which the exhaust ports P19 and P29 are opened, as described above. . In other words, when the exhaust solenoid valves V19 and V29 are in the open state, high pressure gas is exhausted from the intermediate chambers R1 and R2, and when the exhaust solenoid valves V19 and V29 are in the closed state, high pressure gas is discharged in the intermediate chambers R1 and R2. Gas is retained.

In this embodiment, in the solenoid valve units 51 and 52, not only the connection solenoid valves V11 to V18 and V21 to V28 but also the air supply solenoid valves V10 and V20 and the exhaust solenoid valves V19 and V29 are used as two-way valves. There is. In this case, the flow path design of the electromagnetic valve units 51 and 52 becomes even simpler. In addition, in the solenoid valve units 51 and 52, if a two-way valve is provided only for the exhaust solenoid valves V19 and V29 without providing the air supply solenoid valves V10 and V20, the air supply solenoid valves V10 and V20 are unnecessary. Therefore, the number of parts of the solenoid valve units 51 and 52 can be reduced accordingly. However, the air supply solenoid valves V10, V20 and the exhaust solenoid valves V19, V29 are not limited to two-way valves. For example, the air supply solenoid valves V10, V20 and the exhaust solenoid valves V19, V29 provide fluid connections between the air supply ports P10, P20 and the intermediate chambers R1, R2, and between the exhaust ports P19, P29 and the intermediate chambers R1, R2. It may be a single three-way valve that integrally switches between the fluid connections. In this way, the high pressure gas can be supplied to the intermediate chambers R1, R2 and the high pressure gas can be discharged from the intermediate chambers R1, R2 using one solenoid valve instead of two solenoid valves. Therefore, also in this case, the number of parts of the electromagnetic valve units 51 and 52 can be reduced.

The connection solenoid valves V11 to V18 and V21 to V28 are preferably normally closed valves that close the connection ports P11 to P18 and P21 to P28 when power is not supplied. When connecting solenoid valves V11 to V18 and V21 to V28 are configured with normally closed valves, connection ports P11 to P18 and P21 to P28 are sealed even if no power is supplied to connecting solenoid valves V11 to V18 and V21 to V28. be done. In this case, the air pressure of the gas chambers 211-218, 221-228 that are fluidly connected to the connection ports P11-P18, P21-P28 can be maintained. Thereby, the gas massage machine 1 can be operated with low power consumption. However, the connection solenoid valves V11 to V18 and V21 to V28 may be normally open valves that open the connection ports P11 to P18 and P21 to P28 when power is not supplied.

The common tank 53 collectively accommodates the high pressure gas supplied to the electromagnetic valve units 51 and 52. In this embodiment, the common tank 53 is in fluid connection with the gas supply device 4 . Thereby, high pressure gas is supplied from the gas supply device 4 to the common tank 53. The common tank 53 is also fluidly connected to the intermediate chambers R1, R2 of the solenoid valve units 51, 52 via the air supply ports P10, P20 of the solenoid valve units 51, 52, as shown in FIGS. 6A to 6D. is configured to do so. Thereby, the high-pressure gas contained in the common tank 53 is supplied to the intermediate chambers R1, R2 of the solenoid valve units 51, 52 via the air supply ports P10, P20 of the solenoid valve units 51, 52. In this way, the common tank 53 can be fluidly connected to the intermediate chambers R1, R2 of the solenoid valve units 51, 52, so that the common tank 53 connects the first solenoid valve unit 51 and the second solenoid valve unit 52. High pressure gas can be supplied all at once. Therefore, it is not necessary to connect each of the first solenoid valve unit 51 and the second solenoid valve unit 52 to the gas supply device 4, and the first solenoid valve unit 51 and the second solenoid valve unit 52 are connected to the gas supply device. 4 can be simplified.

In the present embodiment, the common tank 53 includes a first in-tank flow path 534a that accommodates high-pressure gas, and a first in-tank flow path 534a that receives high-pressure gas, as shown in FIGS. 6A to 6D. It includes a receiving port 531 for sending out high-pressure gas from the first in-tank flow path 534a, and a first sending port 532a and a second sending port 532b for sending out high-pressure gas from the first in-tank flow path 534a. The receiving port 531 is connected to the gas supply device 4, and the first delivery port 532a and the second delivery port 532b are connected to the air supply ports P10 and P20 of the first and second electromagnetic valve units 51 and 52, respectively. be done. In the common tank 53, the high-pressure gas supplied from the gas supply device 4 through the receiving port 531 is accommodated in the first in-tank channel 534a, and the high-pressure gas accommodated in the first in-tank channel 534a is is delivered to the intermediate chambers R1, R2 of the first and second electromagnetic valve units 51, 52 via the first delivery port 532a and the second delivery port 532b. Note that, in this embodiment, the air supply ports P10 and P20 are directly connected to the first delivery port 532a and the second delivery port 532b by fitting. Thereby, the connection between the two can be simplified. However, the two may be indirectly connected via a known hose or the like.

The common tank 53 further fluidically connects the solenoid valve blocks 500 forming the solenoid valve units 51, 52 to each other. In this embodiment, each open port (corresponding to intermediate ports P100, P190, P200, and P290) of the solenoid valve block 500 is connected via the common tank 53, so that each intermediate chamber of the solenoid valve block 500 Ra are fluidly connected to each other.

The common tank 53 also includes a third relay port 533c and a fourth relay port 533d that relay the high-pressure gas flow path, and a third relay port 533c and a fourth relay port 533d that fluidly connect the third relay port 533c and the fourth relay port 533d. and an in-tank flow path 534c. The open port (corresponding to intermediate port P200) of one solenoid valve block 500 constituting the second solenoid valve unit 52 is fluidly connected to the fourth relay port 533d via the hose H5, and the second solenoid valve block The open port (corresponding to intermediate port P290) of the other electromagnetic valve block 500 constituting 52 is fluidly connected to the third relay port 533c via a hose H6.

In addition, in this embodiment, the connection between the first relay port 533a and the intermediate port P190 of the first electromagnetic valve unit 51, and the connection between the second relay port 533b and the intermediate port P100 of the first electromagnetic valve unit 51 are described. , the connection between the third relay port 533c and the intermediate port P290 of the second electromagnetic valve unit 52, and the connection between the fourth relay port 533d and the intermediate port P200 of the second electromagnetic valve unit 52 are connected to the hose H3. This is done indirectly via ~H6. However, these connections may also be made directly by fitting.

One surface of the common tank 53 serves as an installation surface for attaching the solenoid valve units 51 and 52, and the other surface of the common tank 53 serves as a mounting surface for attaching the solenoid valve units 51 and 52. 3) serves as an installation surface for mounting the common tank 53 inside. The common tank 53 is not particularly limited as long as it has a rigidity that can suppress deformation due to the pressure of the high-pressure gas, and preferably has a rigidity that can suppress deformation due to the weight of the electromagnetic valve units 51 and 52. Instead, it can be made of a rigid material such as a resin material, a ceramic material, or a metal material.

FIG. 7 shows an example of fluid connection between the massage tool 2 and the electromagnetic valve unit 5 in the gas massage machine 1 of this embodiment. The fluid connection between the massage tool 2 and the electromagnetic valve unit 5 can be determined as appropriate depending on the number of gas chambers to be fluidly connected, the control mode for massaging the body, etc., and is limited to the illustrated example.

Next, the operation of the gas massage machine 1 of this embodiment will be explained with reference to FIG. 7 and FIGS. 8A to 9B. Note that the embodiment of the operation of the gas massage machine 1 shown below is just an example, and the operation of the gas massage machine 1 of the present invention is not limited to the following embodiment. In this specification, by supplying high pressure gas to the gas chambers 211 to 218, 221 to 228 of the massage tool 2, or discharging high pressure gas from the gas chambers 211 to 218, 221 to 228, the gas chambers 211 to 218, The order in which 221 to 228 are expanded or contracted is called a "kneading pattern."

8A to 9B show examples of kneading patterns using the massage tool 2 shown in FIGS. 2A and 2B. When massaging the body to improve the flow of blood and/or lymph fluid, pressure may be applied to the body in order from the tips of the limbs to the torso. As a corresponding kneading pattern by the massage tool 2, as shown in FIGS. 8A and 8B (see also FIGS. 2A and 2B), from the first distal leg gas chamber 211 to the third proximal abdominal region After expanding the gas chambers 211 to 218, 221 to 228 in order up to the gas chamber 228, and maintaining the expanded state of the expanded gas chambers 211 to 218, 221 to 228 (the expanded gas chambers 211 to 218, 221 to 228 ), the gas chambers 211 to 218 and 221 to 228 are sequentially expanded from the first distal leg gas chamber 211 to the third proximal abdominal gas chamber 228 so as to be deflated in the order in which they were inflated. A kneading pattern that causes contraction can be considered. In this specification, this kneading pattern mode and similar kneading pattern modes are referred to as "wave mode." Further, as shown in FIGS. 9A and 9B (see also FIGS. 2A and 2B), the gas chambers 211 to 218 are arranged in order from the first distal leg gas chamber 211 to the third proximal abdominal gas chamber 228. , 221 to 228, and maintains the expansion of the gas chambers 211 to 218, 221 to 227, which have been inflated up to that point, until the third proximal abdominal gas chamber 228 is inflated. It will be done. In this specification, this kneading pattern mode and similar kneading pattern modes are referred to as "squeeze mode."

The gas supply and exhaust system 3 is configured to supply high pressure gas to the leg gas chambers 211 to 218, 221 and the groin gas chamber 222 in this order, as shown in FIGS. 8A to 9B. As a result, after the leg gas chambers 211 to 218, 221 expand, the groin gas chamber 222 expands and compresses the groin, so the lymph flowing from one leg does not flow to the groin. It flows smoothly above body B. Furthermore, when supplying high pressure gas to the leg gas chambers 211 to 218 and 221, the gas supply and exhaust system 3 supplies the high pressure gas to the distal leg gas chambers 211 to 218 and the proximal leg gas chamber 221 in this order. It can be configured as follows. This promotes the flow of lymph fluid from distal to proximal in the legs, thereby smoothing the upward flow of lymph in the legs. The gas supply/exhaust system 3 further supplies high pressure gas to the groin gas chamber 222, and then supplies high pressure gas to the distal abdominal gas chambers 223, 225, 227, and the proximal abdominal gas chambers 224, 226, 228 in this order. It can be configured to: In this way, by inflating the distal abdominal gas chambers 223, 225, and 227, and then inflating the proximal abdominal gas chambers 224, 226, and 228, lymph fluid is transferred from the proximal side of body B to the distal side. On the proximal side of body B, the flow of lymph fluid upwards in body B is promoted while suppressing the flow to the body B. When the distal abdominal gas chambers 223 , 225 , 227 and the proximal abdominal gas chambers 224 , 226 , 228 are each divided into a plurality of sections, the gas supply/exhaust system 3 supplies high-pressure gas to the groin gas chamber 222 . After supplying, the first distal flank gas chamber 223, the first proximal flank gas chamber 224, the second distal flank gas chamber 225, and the second proximal flank gas chamber 226 are supplied, in this order. It can be configured to supply high pressure gas. In this way, the first distal abdominal gas chamber 223 and the second distal abdominal gas chamber 225 distal to the leg gas chambers 211 to 218, 221 are respectively connected to the first distal abdominal gas chamber 225 on the proximal side. The second proximal abdominal gas chamber 224 and the second proximal abdominal gas chamber 226 are expanded before the distal side of the body B is compressed before the proximal side, so that the gas flowing from one leg Lymph fluid flows smoothly upwards of body B without flowing to the inside of body B (to the groin side, lower abdomen side, or navel side). Note that, as in this embodiment, when the number of divisions of each of the distal abdominal gas chambers 223, 225, 227 and the proximal abdominal gas chambers 224, 226, 228 is three or more, the above-mentioned order is followed. Accordingly, high-pressure gas is supplied to the third distal abdominal gas chamber 227, the third proximal abdominal gas chamber 228, and so on in this order.

The control device 6 controls the solenoid valve unit 5 to expand the plurality of gas chambers 211 to 218 and 221 to 228 in order to realize various kneading pattern modes, not only the wave mode and squeeze mode described above. and contraction can be controlled respectively. The control device 6 operates in either an air supply state in which high-pressure gas is supplied to the intermediate chamber R1 of the first solenoid valve unit 51 or an exhaust state in which high-pressure gas is discharged from the intermediate chamber R1 in the first solenoid valve unit 51. The first electromagnetic valve unit 51 is configured to be controllable so that the first electromagnetic valve unit 51 is controlled. Specifically, the air supply state is formed by opening the air supply port P10 of the first solenoid valve unit 51 and closing the exhaust port P19 of the first solenoid valve unit 51; It is formed by closing the air supply port P10 of the first solenoid valve unit 51 and opening the exhaust port P19 of the first solenoid valve unit 51. However, as described above, the air supply state and the exhaust state can also be formed by controlling the opening and closing of the exhaust port P19 while the air supply port P10 remains open. In this case, the air supply solenoid valve V10 of the air supply port P10 may or may not be provided, the air supply state is formed by closing the exhaust port P19, and the exhaust state is formed by closing the exhaust port P19. It is formed by opening the . In this way, the gas chambers 211, 212, 215, 216 of the first massage tool 21 and the gas chamber 221 of the second massage tool 22, which are fluidly connected to the connection ports P11 to P18 of the first electromagnetic valve unit 51, 222, 225, and 226 can receive and discharge high-pressure gas by opening and closing connection ports P11 to P18 using connection solenoid valves V11 to V18. Further, in the present embodiment, the control device 6 controls the air supply state in which high pressure gas is supplied to the intermediate chamber R2 of the second electromagnetic valve unit 52, and the air supply state in which high pressure gas is discharged from the intermediate chamber R2 of the second electromagnetic valve unit 52. The second solenoid valve unit 52 is configured to be controllable so that the exhaust state is set to one of the following exhaust states. Specifically, the air supply state is formed by opening the air supply port P20 of the second solenoid valve unit 52 and closing the exhaust port P29 of the second solenoid valve unit 52; It is formed by closing the air supply port P20 of the second solenoid valve unit 52 and opening the exhaust port P29 of the second solenoid valve unit 52. However, as described above, the air supply state and the exhaust state can also be formed by controlling the opening and closing of the exhaust port P29 while the air supply port P20 remains open. In this case, the air supply solenoid valve V20 of the air supply port P20 may or may not be provided, the air supply state is formed by closing the exhaust port P29, and the exhaust state is formed by closing the exhaust port P29. It is formed by opening the . In this way, the gas chambers 213, 214, 217, 218 of the first massage tool 21 and the gas chamber 223 of the second massage tool 22, which are fluidly connected to the connection ports P21 to P28 of the second solenoid valve unit 52, 224, 227, and 228 can receive and discharge high-pressure gas by opening and closing connection ports P21 to P28 using connection solenoid valves V21 to V28. In this way, the control device 6 independently controls the air supply state and exhaust state of the first solenoid valve unit 51 and the second solenoid valve unit 52, so that the first massage can be performed as described in more detail below. The expansion and contraction of the gas chambers 211 to 218 of the tool 21 and the gas chambers 221 to 228 of the second massage tool 22 can be controlled.

In this embodiment, the control device 6 controls the solenoid valve unit 5 to maintain the expanded or contracted states of the plurality of gas chambers 211 to 218 and 221 to 228, respectively. The control device 6 operates the plurality of gas chambers 211 to 218 and 221 to 228 in a high pressure state where high pressure gas is supplied, a low pressure state where high pressure gas is discharged, and an intermediate pressure state between the high pressure state and the low pressure state. It is also possible to control the air pressure to maintain each pressure. Here, in this specification, a "high pressure state" refers to a state in which a certain gas chamber 211 to 218, 221 to 228 has finished receiving high pressure gas, and a "low pressure state" refers to a state in which a certain gas chamber 211 to 218, 221 has finished receiving high pressure gas. Refers to the state in which high pressure gas has been exhausted from ~228, and the "intermediate pressure state" is the state in which high pressure gas exists in certain gas chambers 211 to 218, 221 to 228 in an amount less than the high pressure state and more than the low pressure state. refers to the state of Specifically, the control device 6 closes the connection ports P11 to P18 of the first solenoid valve unit 51, thereby closing the connection ports P11 to P18 of the first solenoid valve unit 51, respectively. The first solenoid valve unit 51 is configured to block high-pressure gas from entering and leaving the gas chambers 211, 212, 215, 216 of the first massage tool 21 and the gas chambers 221, 222, 225, 226 of the second massage tool 22. It is configured to be controllable. Therefore, the gas chambers 211, 212, 215, 216 of the first massage tool 21 and the gas chambers 221, 222, 225, 226 of the second massage tool 22 are connected to the connecting solenoid valve V11 of the first solenoid valve unit 51. By closing the connection ports P11 to P18 of the first electromagnetic valve unit 51 by ~V18, not only the expanded state or the deflated state is maintained, but also the pressure of the supplied high pressure gas is lowered as described above. It is also possible to maintain low to moderate levels of air pressure. In addition, the control device 6 closes the connection ports P21 to P28 of the second solenoid valve unit 52, thereby controlling the first massager fluidly connected to the connection ports P21 to P28 of the second solenoid valve unit 52, respectively. The second electromagnetic valve unit 52 can be controlled to block high pressure gas from entering and leaving the gas chambers 213, 214, 217, 218 of the tool 21 and the gas chambers 223, 224, 227, 228 of the second massage tool 22. It is configured. Therefore, the gas chambers 213, 214, 217, 218 of the first massage tool 21 and the gas chambers 223, 224, 227, 228 of the second massage tool 22 are connected to the connecting solenoid valve V21 of the second solenoid valve unit 52. By closing the connection ports P21 to P28 of the second electromagnetic valve unit 52 by ~V28, not only the expanded state or the deflated state is maintained, but also the pressure of the supplied high pressure gas is lowered as described above. It is also possible to maintain low to moderate levels of air pressure.

Table 1 shows the operations of the first solenoid valve unit 51 and the second solenoid valve unit 52 for implementing the wave mode as shown in FIGS. 8A and 8B by the gas massage machine 1 of this embodiment. An example is shown. When executing the wave mode, the control device 6 can control the first solenoid valve unit 51 and the second solenoid valve unit 52 as follows. Here, of the plurality of gas chambers 211 to 218 and 221 to 228, the first to fourth gas chambers that are continuously expanded will be described. In addition, in the following explanation, attention will be paid to the first distal leg gas chamber 211 to the fourth distal leg gas chamber 214 of the first massage tool 21, and for convenience of explanation, the first distal leg gas chamber 211 to the fourth distal leg gas chamber 214 will be focused on. The gas chambers 211 to 4th distal leg gas chambers 214 are simply referred to as "first to fourth gas chambers 211 to 214."

First, in consecutive first and second periods, the first solenoid valve unit 51 is brought into the air supply state, and the second solenoid valve unit 52 is brought into the exhaust state. Then, in the first period, the first connection port P11 of the first solenoid valve unit 51, which is fluidly connected to the first gas chamber 211, is opened (if it is opened, it is left open). , the second connection port P12 of the first electromagnetic valve unit 51 fluidly connected to the second gas chamber 212 is kept closed (if not closed, it is closed). During this period, the first gas chamber 211 gradually receives high-pressure gas, and the atmospheric pressure of the first gas chamber 211 increases (see the first diagram from the top on the left in FIG. 8A). Hereinafter, this state will be referred to as a "pressure increase state." In the second period following the first period, the first connection port P11 of the first solenoid valve unit 51 is closed, and the second connection port P12 of the first solenoid valve unit 51 is opened. During this period, the first gas chamber 211 holds high-pressure gas, and the atmospheric pressure of the first gas chamber 211 is maintained within a predetermined range. Hereinafter, this state will be referred to as a "high pressure holding state." Further, the second gas chamber 212 is in an increased pressure state (see the second diagram from the top on the left in FIG. 8A). Next, in a third period and a fourth period that are continuous after the first period and the second period, the first solenoid valve unit 51 is brought into the exhaust state, and the second solenoid valve unit 52 is brought into the air supply state. Then, in the third period, the first connection port P11 of the first solenoid valve unit 51 is opened, the second connection port P12 of the first solenoid valve unit 51 is closed, and the third gas chamber is closed. The first connection port P21 of the second solenoid valve unit 52 fluidly connected to the second solenoid valve unit 213 is opened (if opened, remains open), and the second solenoid valve unit 52 is fluidly connected to the fourth gas chamber 214. The second connection port P22 of the solenoid valve unit 52 is kept closed (if it is not closed, it is closed). During this period, the first gas chamber 211 gradually discharges the high-pressure gas, and the air pressure in the first gas chamber 211 decreases. Hereinafter, this state will be referred to as a "reduced pressure state." Further, the second gas chamber 212 is in a high pressure state, and the third gas chamber 213 is in an increased pressure state (see the third figure from the top on the left in FIG. 8A, the first gas chamber 211 is in a high pressure state). (This indicates a state in which high-pressure gas has not been completely exhausted and remains.) In the fourth period following the third period, the first connection port P11 of the first solenoid valve unit 51 is closed, the second connection port P12 of the first solenoid valve unit 51 is opened, and the second solenoid valve unit 51 is closed. The first connection port P21 of the valve unit 52 is closed, and the second connection port P22 of the second electromagnetic valve unit 52 is opened. During this period, the first gas chamber 211 maintains a state in which the high-pressure gas has almost been exhausted, as before receiving the high-pressure gas. Hereinafter, this state will be referred to as a "low pressure holding state." The second gas chamber 212 is in a reduced pressure state, the third gas chamber 213 is in a high pressure maintained state, and the fourth gas chamber 214 is in an increased pressure state (in FIG. 8A, the fourth gas chamber from the top on the left (Refer to the figure, the second gas chamber 212 shows a state in which high-pressure gas remains without being completely exhausted). Next, the second solenoid valve unit 52 is brought into the exhaust state in a fifth period and a sixth period that are continuous after the third period and the fourth period. Then, in the fifth period, the second connection port P12 of the first solenoid valve unit 51 is closed, the first connection port P21 of the second solenoid valve unit 52 is opened, and the second solenoid valve The second connection port P22 of the unit 52 is closed. During this period, the second gas chamber 212 is in a low-pressure state, the third gas chamber 213 is in a reduced-pressure state, and the fourth gas chamber 214 is in a high-pressure state (upper right corner in FIG. 8A). (Refer to the first figure, the third gas chamber 213 shows a state in which the high-pressure gas has not been completely exhausted and remains). In the sixth period following the fifth period, the first connection port P21 of the second solenoid valve unit 52 is closed, and the second connection port P22 of the second solenoid valve unit 52 is opened. During this period, the third gas chamber 213 is in a low pressure state, and the fourth gas chamber 214 is in a reduced pressure state (see the second figure from the top on the right in FIG. 8A, the fourth gas chamber 214 is in a low pressure state). (indicates that high-pressure gas has not been completely exhausted and remains).

Such a series of operations is carried out by the third connection port P13 and the fourth connection port P14 of the first electromagnetic valve unit 51, which are fluidly connected to the other gas chambers 215 to 218 of the first massage tool 21, and The same process is performed for the third connection port P23 and the fourth connection port P24 of the second electromagnetic valve unit 52 during the fifth period to the tenth period. Further, the fifth to eighth connection ports P15 to P18 of the first solenoid valve unit 51 are fluidly connected to the gas chambers 221 to 228 of the second massage tool 22, and the fifth to P18 of the second solenoid valve unit 52 are connected fluidly to the gas chambers 221 to 228 of the second massage tool 22. For the eighth connection ports P25 to P28, such a series of operations is similarly performed in the ninth to 18th periods. Thereby, the wave mode can be implemented in the first massage tool 21 and the second massage tool 22.

In the wave mode shown in FIGS. 8A and 8B, during the first period to the 18th period, lymph fluid flowing from the legs does not stay in the groin area of body B but flows upwards of body B. or from the third distal flank gas chamber 227 and the third proximal flank gas chamber 228. It corresponds to a further superior position and reaches the proximal axillary lymph node where the lymph vessels join. At that time, the first distal flank gas chamber 223, the first proximal flank gas chamber 224, the second distal flank gas chamber 225, the second proximal flank gas chamber 226, and the third By expanding the gas chambers in the order of the distal abdominal gas chamber 227 and the third proximal abdominal gas chamber 228, both the distal side body B and the proximal side body B of the second massage tool 22 are expanded. Lymph flows into the proximal axillary lymph nodes at different times, rather than at the same time. Therefore, the lymph fluid flowing upward from the left and right sides of the crotch of body B is expected to flow smoothly in the proximal axillary lymph nodes without colliding.

Note that, as shown in Table 1, the control device 6 controls the air supply port of the first solenoid valve unit 51 during a period in which all of the connection ports P11 to P18 of the first solenoid valve unit 51 are in a closed state. The first solenoid valve unit 51 may be controlled to close both P10 and exhaust port P19 (see the 17th period and the 18th period in the first solenoid valve unit 51). In this way, the gas chambers 211, 212, 215, 216, 221, which are fluidly connected to the first electromagnetic valve unit 51, without operating the air supply electromagnetic valve V10 and the exhaust electromagnetic valve V19 in vain. Atmospheric pressures of 222, 225, and 226 can be maintained. Furthermore, when the air supply solenoid valve V10 and the exhaust solenoid valve V19 are always closed, the power consumption of the gas massage machine 1 is suppressed. On the contrary, when the air supply solenoid valve V10 and the exhaust solenoid valve V19 are always open, the control device 6 controls the connection ports P11 to P18 of the first solenoid valve unit 51. The first electromagnetic valve unit 51 may be controlled to open both the air supply port P10 and the exhaust port P19 of the first electromagnetic valve unit 51 during the closed state. For the same reason, the control device 6 controls the air supply port P20 and the exhaust port P29 of the second solenoid valve unit 52 during a period in which all of the connection ports P21 to P28 of the second solenoid valve unit 52 are in a closed state. The second solenoid valve unit 52 may be controlled to close or open both. Furthermore, the control device 6 controls the gas supply device 4 to The supply of high pressure gas to the solenoid valve unit 5 may be stopped.

Table 2 shows the operations of the first solenoid valve unit 51 and the second solenoid valve unit 52 for implementing the squeeze mode as shown in FIGS. 9A and 9B by the gas massage machine 1 of this embodiment. An example is shown. When executing the squeeze mode, the control device 6 can control the first solenoid valve unit 51 and the second solenoid valve unit 52 as follows. Here, the first to fourth gas chambers 211 to 214 that are continuously expanded among the plurality of gas chambers 211 to 218 and 221 to 228 will be described in the same way as in the description of Table 1. In the first period and the second period, the first solenoid valve unit 51 is brought into the air supply state, and in the third period and the fourth period, the second solenoid valve unit 52 is brought into the air supply state. Then, in the first period and the second period, the first connection port P11 and the second connection port of the first solenoid valve unit 51 connected to the first gas chamber 211 and the second gas chamber 212 are The connection ports are opened in the order of P12, and in the third and fourth periods, the first connection ports P21 and P21 of the second electromagnetic valve unit 52 connected to the third gas chamber 213 and the fourth gas chamber 214 are opened. After opening the connection ports in the order of the second connection port P22, the connection ports are closed in order. As a result, the first to fourth gas chambers 211 to 214 are brought into a pressure increasing state and then into a high pressure holding state (see the first to fourth diagrams from the top on the left in FIG. 9A).

Before setting the first solenoid valve unit 51 and the second solenoid valve unit 52 to the exhaust state, the first solenoid valve unit 51 that is fluidly connected to the other gas chambers 215 to 218 of the first massage tool 21 is opened. The third connection port P13 and the fourth connection port P14, as well as the third connection port P23 and the fourth connection port P24 of the second solenoid valve unit 52, are also like this in the fifth period to the eighth period. Perform the same series of actions. Further, the fifth to eighth connection ports P15 to P18 of the first solenoid valve unit 51 are fluidly connected to the gas chambers 221 to 228 of the second massage tool 22, and the fifth to P18 of the second solenoid valve unit 52 are connected fluidly to the gas chambers 221 to 228 of the second massage tool 22. For the eighth connection ports P25 to P28, such a series of operations is similarly performed in the ninth to 16th periods. Finally (17th period), after the first solenoid valve unit 51 and the second solenoid valve unit 52 are in the exhaust state, all the connections of the first solenoid valve unit 51 and the second solenoid valve unit 52 are Ports P11 to P18 and P21 to P28 are opened simultaneously. As a result, all the gas chambers 211 to 218 and 221 to 228 are brought into a reduced pressure state at the same time, and then brought into a low pressure maintained state (see the bottom diagram on the right in FIG. 9B). Thereby, the squeeze mode can be implemented in the first massage tool 21 and the second massage tool 22.

In the squeeze mode shown in FIGS. 9A and 9B, during the first period to the 16th period, lymph fluid flowing from the legs does not flow to the inside of body B (groin area, lower abdomen side, and navel side). Flowing upwards in body B promotes the normal flow of lymph fluid.

In this way, in the gas massage machine 1 of this embodiment, the control device 6 can independently control the air supply state and exhaust state of the first solenoid valve unit 51 and the second solenoid valve unit 52. It is configured. Furthermore, the control device 6 independently controls the supply and discharge of high-pressure gas to the connection ports P11 to P18 of the first solenoid valve unit 51 and the connection ports P21 to P28 of the second solenoid valve unit 52. However, they are configured to be able to independently shut off the inflow and outflow of high-pressure gas. Therefore, in the gas massage machine 1 of the present embodiment, each of the gas chambers 211 to 218 and 221 to 228 can be set to an increased pressure state, a high pressure maintenance state, a reduced pressure state, or a low pressure maintenance state. As a result, although the gas massage machine 1 of this embodiment employs two-way valves as the connection solenoid valves V11 to V18 and V21 to V28, it can be used in various massage modes such as wave mode and squeeze mode. Pattern mode can be implemented.

In the examples of the kneading patterns in Tables 1 and 2, most of the connection solenoid valves V11 to V18 and V21 to V28 are in the closed state. Therefore, when the connecting solenoid valves V11 to V18 and V21 to V28 are normally closed, it is not necessary to supply much power to the first solenoid valve unit 51 and the second solenoid valve unit 52. The gas massage machine 1 can be operated with low power consumption. Note that, as shown in FIGS. 8A to 9B, when the first massage tool 21 is not attached to the right leg but is attached to the left leg, in the examples of the kneading patterns in Tables 1 and 2, The opening/closing order of the fifth connection port P25 and the sixth connection port P26 of the second solenoid valve unit 52 is changed, and the seventh connection port P17 and the eighth connection port P18 of the first solenoid valve unit 51 are changed. The opening and closing order of the seventh connection port P27 and the eighth connection port P28 of the second electromagnetic valve unit 52 may be changed. In this way, even when the first massage tool 21 is attached to the left leg, the wave mode and the squeeze mode can be realized in the same way as when the first massage tool 21 is attached to the right leg.

As shown in FIGS. 3 and 10A to 11B, the gas massage machine 1 of this embodiment has a plurality of gas chambers 211 to 218, 221 to 228 (see FIGS. 2A and 2B) of the massage tool 2, respectively. It may further include an emergency stop structure 7 for forcibly discharging high-pressure gas. In the gas massage machine 1 of this embodiment, when normally closed two-way valves are used as the connecting solenoid valves V11 to V18 and V21 to V28, the solenoid valve units 51 and 52 are disconnected from the power supply in an emergency such as a power outage. When power is no longer supplied, the connection ports P11 to P18 and P21 to P28 remain closed, and high pressure gas may remain stored in the gas chambers 211 to 218 and 221 to 228 within the massage tool 2. There is sex. Therefore, the massage recipient's body B remains under pressure from the gas chambers 211-218, 221-228. At this time, the patient may feel discomfort and may be required to quickly release the body B from the compressed state. Even in such a case, the gas massage machine 1 of this embodiment can release the body B from the compressed state by the emergency stop structure 7.

The emergency stop structure 7 connects the gas chambers 211 to 218, 221 to 228 (see FIGS. 2A and 2B) of the massage tool 2 and the gas supply and exhaust system 3, as shown in FIGS. 3 and 10A to 11B. The connector C is provided with a connector C, and a decoupling device 70 for decoupling the connector C. The emergency stop structure 7 releases the connection of the connector C by the connection release device 70 and forcibly discharges high pressure gas from the gas chambers 211 to 218 and 221 to 228 of the massage tool 2.

When the gas chamber side connectors C12, C22 are housed in the housing space for the gas chamber side connectors C12, C22, the engaging portions Z1, Z2 enter into the housing space and close the gas chamber side connectors C12. , C22 can be engaged with the engaged parts G1 and G2. On the other hand, the engaging portions Z1 and Z2 can be disengaged from the engaged portions G1 and G2 by leaving the accommodation space thereof.

In this modification, the engaging portions Z1 and Z2 are restricted from moving in the coupling release direction X2 with respect to the electromagnetic valve unit side connectors C11 and C21. This is, for example, so that the entire coupling release device 70 including the pressing member 71 is restricted from moving in the coupling release direction X2 with respect to the casing 3a to which the solenoid valve unit side connectors C11 and C21 are attached. This can be realized by being attached to the housing 3a. Alternatively, this can also be realized by the engaging portions Z1, Z2 coming into contact with the peripheral walls of the through holes T2, T3 of the electromagnetic valve unit side connectors C11, C21 in the coupling release direction X2. In this modification, since the engaging parts Z1, Z2 are restricted from moving in the coupling release direction X2 with respect to the solenoid valve unit side connectors C11, C21 in this way, the engaging parts Z1, Z2 By engaging the engaged parts G1 and G2 in the coupling release direction X2, the coupling between the electromagnetic valve unit side connectors C11 and C21 and the gas chamber side connectors C12 and C22 is maintained.

Next, the operation of an example of the emergency stop structure 7 of the gas massage machine 1 of this modification will be described. Note that the following example is just an example, and the operation of the emergency stop structure in the gas massage machine of the present invention is not limited to the following example.

In the normal state shown in FIGS. 12 and 14 (when the connector C is in the coupled state), the engaging parts Z1 and Z2 of the coupling release device 70 are inserted into the through holes T2 and T3 of the solenoid valve unit side connectors C11 and C21. It is inserted and engaged with the engaged parts G1 and G2 of the gas chamber side connectors C12 and C22. At this time, since the engaging parts Z1, Z2 are restricted from moving in the coupling release direction X2 with respect to the solenoid valve unit side connectors C11, C21, the engaging parts Z1, Z2 and the engaged part G1, By engaging G2 in the coupling release direction X2, the coupling between the electromagnetic valve unit side connectors C11, C21 and the gas chamber side connectors C12, C22 is maintained. At the same time, the biasing members U1 and U2 bias the solenoid valve unit side connectors C11 and C21 in the direction of releasing the connection between the gas chamber side connectors C12 and C22, but the engaging parts Z1 and Z2 Since the engaged parts G1 and G2 are engaged in the coupling release direction X2, the coupling between the electromagnetic valve unit side connectors C11 and C21 and the gas chamber side connectors C12 and C22 is maintained.

By moving along the pressing direction Pr, the engaging parts Z1 and Z2 disengage from the through holes T2 and T3 of the solenoid valve unit side connectors C11 and C21, and become engaged parts of the gas chamber side connectors C12 and C22. The engagement with G1 and G2 is released.

When the engagement between the engaging parts Z1, Z2 and the engaged parts G1, G2 is released, the connection between the solenoid valve unit side connectors C11, C21 and the gas chamber side connectors C12, C22 is released. The force is released, and as shown in FIGS. 13 and 15, the gas chamber side connectors C12 and C22 separate in the coupling release direction X2 relative to the electromagnetic valve unit side connectors C11 and C21. As a result, the fluid connection between the gas chambers 211 to 218, 221 to 228 (see FIGS. 2A and 2B) of the massage tool 2 and the solenoid valve unit 5 of the gas supply and exhaust system 3 is released, and the gas chambers 211 to 218, The high pressure gas stored in 221 to 228 is discharged.

In this modification, the coupling release device 70 includes engaging portions Z1 and Z2 that engage with the engaged portions G1 and G2 of the gas chamber side connectors C12 and C22, and the engaging portions Z1 and Z2 are It is connected to member 71. Therefore, the coupling release device 70 does not require a complicated mechanism for releasing the coupling between the electromagnetic valve unit side connectors C11 and C21 and the gas chamber side connectors C12 and C22, and has a very simple configuration. By simply moving the member 71 in the pressing direction Pr, the connection between the electromagnetic valve unit side connectors C11 and C21 and the gas chamber side connectors C12 and C22 can be released.

A flow path is provided.
As a result, even if the arrangement of the connection ports P11 to P18 and P21 to P28 of the solenoid valve unit 5 does not match the arrangement of the connection ports of the solenoid valve unit side connectors C110 and C210, the flow path of the support member 83 The connection ports are fluidly connected to each other.

In this embodiment, as shown in FIG. 17, the biasing members U10 and U20 include biasing force generating portions U110 and U210 and pressure portions U120 and U220, similarly to the first embodiment. In this embodiment, since the first connector C10 is larger than the second connector C20, the second solenoid valve unit is connected between the first solenoid valve unit side connector C110 and the first gas chamber side connector C120. In order to generate the same biasing pressure as between the side connector C210 and the second gas chamber side connector C220, the biasing member U10 for the first connector C10 is more biased than the biasing member U20 for the second connector C20. There are also a large number of biasing members U10 (in the illustrated example, there are a plurality (three) of biasing members U10 and one biasing member U20). The other configurations of the biasing members U10 and U20 are the same as those in the first embodiment, so their description will be omitted here.

(partially not shown). At this time, the engaging parts Z10, Z20 and the engaged parts G10, G20 engage in the decoupling direction X2, thereby restricting the movement of the solenoid valve unit side connectors C110, C210 in the decoupling direction X2. Therefore, the connection between the solenoid valve unit side connectors C110, C210 and the gas chamber side connectors C120, C220 is maintained (some are not shown). At the same time, the biasing members U10, 20 bias the solenoid valve unit side connectors C110, C210 and the gas chamber side connectors C120, C220 in a direction to release the coupling from each other. Since the engaging parts G10 and G20 are engaged in the coupling release direction X2, the coupling between the solenoid valve unit side connectors C110 and C210 and the gas chamber side connectors C120 and C220 is maintained (some parts are not shown in the figure). omission).

In an emergency such as a power outage, when the pressing member 81 of the coupling release device 80 is pressed in the pressing direction Pr, as shown in FIG. 18, as the pressing member 81 moves in the pressing direction Pr, the pressing member 81 The abutting portions 811a, 812a move in the pressing direction Pr and abut against the abutted portions 821a, 822a of the rotating members 821, 822. Furthermore, when the pressing member 81 is pressed in the pressing direction Pr, as shown in FIG. Rotating around the axis R0, the engaging portions Z10 and Z20 of the rotating members 821 and 822 move in a direction opposite to the pressing direction Pr (some portions are not shown). As a result, the engagement of the gas chamber side connectors C120, C220 with the engaged parts G10, G20 is released (some are not shown).

When the engagement between the engaging portions Z10, Z20 and the engaged portions G10, G20 is released, the urging force of the urging members U10, U20 is released, and as shown in FIG. 19, the gas chamber side connector C120 , C220 are detached in the coupling release direction X2 relative to the solenoid valve unit side connectors C110 and C210 (some are not shown).

Furthermore, when the pressing member 81 of the coupling release device 80 is pressed in the pressing direction Pr, as shown in FIG. They are inserted into the accommodating parts C1100 and C2100 through the through holes TH1 and TH2 of C1101 and C2101 (some parts are not shown). When inserted into the accommodating parts C1100, C2100, the insertion parts 811p, 812p connect the bottom walls C1102, C2102 of the solenoid valve unit side connectors C110, C210 and the bottom walls C1202, C2202 of the gas chamber side connectors C120, C220. The connectors are inserted between the solenoid valve unit side connectors C110, C210 and the gas chamber side connectors C120, C220 so as to be pressed in the direction away from each other (some are not shown). As a result, as shown in FIG. 20, the separation of the gas chamber side connectors C120 and C220 in the decoupling direction X2 is further promoted (some are not shown).

In this embodiment, the coupling release device 80 includes rotating members 821 and 822, and when the pressing member 81 is pressed in the pressing direction Pr, the rotating members 821 and 822 rotate around the rotation axis R0. In this way, when the rotating members 821 and 822 are used, for example, the force Pr in the pressing direction Pr to the pressing member 81 is applied to the rotating members 821 and 822 (specifically, the force point where the rotating members 821 and 822 are contacted) 821a, 822a) and the fulcrum of rotation of the rotating members 821, 822 (specifically, the shaft portions 821r, 822r of the rotating members 821, 822), the amount of force applied to the rotating members 821, 822 around the rotation axis R0 The magnitude of rotational moment can be adjusted. Thereby, it is possible to adjust the ease with which the coupling release device 80 releases the coupling between the electromagnetic valve unit side connectors C110 and C210 and the gas chamber side connectors C120 and C220 (in this embodiment, in the rotating members 821 and 822, By providing the shaft portions 821r, 822r and the abutted portions 821a, 822a at both ends of the rotating members 821, 822 in the coupling direction (It is set so that the connection with the connectors C120 and C220 can be easily released).

Furthermore, in this embodiment, when the coupling release device 80 releases the coupling between the solenoid valve unit side connectors C110, C210 and the gas chamber side connectors C120, C220, the gas chamber side connectors C120, C220 , U20 in the coupling release direction X2, and presses the solenoid valve unit side connectors C110, C210 and the gas chamber side connectors C120, C220 in the direction away from each other. 812p is inserted between the solenoid valve unit side connectors C110, C210 and the gas chamber side connectors C120, C220. By doing so, the gas chamber side connectors C120, C220 are separated from the solenoid valve unit side connectors C110, C210, such as the gas chamber side connectors C120, C220 remaining in the housing parts C1100, C2100 of the solenoid valve unit side connectors C110, C210. Since it is possible to prevent the high-pressure gas from completely separating, the high-pressure gas can be discharged from the gas chamber of the massage tool more quickly.
