In the embodiment, the inflation space of the air bag body 42 is formed by the air bag body 42, the first fixed plate 43 and the second fixed plate 44. Moreover, the first fixed plate 43 and the second fixed plate 44 are connected to the first end and the second end of the telescopic shaft 41 respectively, so that the telescopic shaft 41 is arranged in the air bag body 42, and the inflation space of the air bag body 42 is formed by the telescopic shaft 41, the air bag body 42, the first fixed plate 43 and the second fixed plate 44, and the inflation space can not include the space inside the telescopic shaft 41.

[0077] The air hole for realizing the fluid communication between the air bag body 42 and the external air source can be directly arranged on at least one of the first fixed plate 43, the second fixed plate 44 and the telescopic shaft 41, without the need of arranging an additional pipeline to connect the inflation space of the air bag body 42 with the air connection head outside the massage movement 100 or to realize the fluid communication with the external air source, which is beneficial to reduce the cost of the massage movement 100 and make the telescopic member 4 more compact and smaller in size. Alternatively, the air bag body 42 can have any configuration, including a cylindrical shape, a columnar shape or a bellows shape, etc.

[0078] In some embodiments, referring to Figures 3 to 5 The telescopic member 4 further comprises a first press-fit plate 46, and the first end of the air bag body 42 is sealingly engaged with the first fixed plate 43 through the first press-fit plate 46. Exemplarily, the first fixed plate 43 is provided with an annular press-fit groove, the first press-fit plate 46 is an annular press-fit plate adapted to the annular press-fit groove of the first fixed plate 43, and the edge of the opening of the first end of the air bag body 42 is clamped between the first fixed plate 43 and the first press-fit plate 46, and the first press-fit plate 46 is used to press-fit the opening edge of the first end of the air bag body 42 into the annular press-fit groove, so as to realize the sealing engagement between the opening edge of the first end of the air bag body 42 and the first press-fit plate 46. Alternatively, the first press-fit plate 46 and the first fixed plate 43 can be further fixedly connected by screws or bolts, so as to prevent the first end of the air bag body 42 from falling off.

[0079] In some embodiments, referring to Figures 3 to 5The telescopic member 4 further comprises a second pressing plate 47, and the second end of the air bag body 42 is sealingly connected to the second fixed plate 44 through the second pressing plate 47. For example, the second fixed plate 44 can be provided with a ring-shaped pressing groove similar to the ring-shaped pressing groove of the first fixed plate 43, and the second pressing plate 47 is a ring-shaped pressing plate matched with the ring-shaped pressing groove of the second fixed plate 44. The edge of the opening of the second end of the air bag body 42 is clamped between the second fixed plate 44 and the second pressing plate 47, and the second pressing plate 47 is matched to press the edge of the opening of the second end of the air bag body 42 into the ring-shaped pressing groove of the second fixed plate 44, so as to achieve the sealing connection between the edge of the opening of the second end of the air bag body 42 and the first pressing plate 46. Alternatively, the second pressing plate 47 and the second fixed plate 44 can be further fixedly connected through screws or bolts to prevent the second end of the air bag body 42 from falling off.

[0080] In some other embodiments, the air bag body 42 is in the form of a bag. That is, the inflation space of the air bag body 42 is defined by itself, and is arranged outside the telescopic shaft 41 and does not jointly enclose at least one of the first fixed plate 43, the second fixed plate 44 and the telescopic shaft 41.

[0081] When the inflation space of the air bag body 42 is inflated, the air bag body 42 expands and stretches, drives the first fixed plate 43 away from the second fixed plate 44, and drives the telescopic shaft 41 to elongate. When the air bag body 42 is deflated, the first fixed plate 43 can be driven by an external force and / or the air bag body 42 to be close to the second fixed plate 44, and the telescopic shaft 41 is driven to contract.

[0082] In some embodiments, referring to Figures 3 to 5 At least one of the first fixed plate 43 and the second fixed plate 44 is detachably connected to the telescopic shaft 41. By detachably connecting the first fixed plate 43 and / or the second fixed plate 44 to the telescopic shaft 41, when the air bag body 42 is installed or removed, one of the first fixed plate 43 and the second fixed plate 44 is detached from the telescopic shaft 41, so that the telescopic shaft 41 is convenient to be arranged in the air bag body 42, and the air bag body 42 is convenient to be installed or removed. Alternatively, the first fixed plate 43 is fixedly connected to the first end of the telescopic shaft 41. Alternatively, the second fixed plate 44 is detachably connected to the second end of the telescopic shaft 41.

[0084] In some embodiments, the driving device 3 is in transmission connection with the telescopic shaft 41 of the telescopic member 4, and drives the whole telescopic member 4 including the telescopic shaft 41 and the air bag body 42 to rotate to transmit torque. The driving device 3 is directly in transmission connection with the telescopic shaft 41, or is in transmission connection with the telescopic shaft 41 through the transmission member 45.

[0085] In some embodiments, referring to Figures 3 to 5 The telescopic member 4 further comprises a transmission member 45, and the driving device 3 is in transmission connection with the telescopic shaft 41 through the transmission member 45.

[0086] The transmission member 45 is specifically a shaft body, the first end of the transmission member 45 is connected with the telescopic shaft 41, and the second end of the transmission member 45 is in transmission connection with the driving device 3. Exemplarily, the worm gear 31 is assembled on the transmission member 45, for example, the worm gear 31 is sleeved on the transmission member 45 and is in clamping connection through the spline, so that the transmission member 45 is in transmission connection with the worm gear 31. When the motor 33 drives the worm gear 31 to rotate through the worm 32, the transmission member 45 can be driven to rotate, and then the telescopic shaft 41 is driven to rotate.

[0087] The transmission member 45 is provided with an air channel 451 in fluid connection with the inflation space in the air bag body 42. The air channel 451 extends from the second end face of the transmission member 45 to the side wall close to the first end face of the transmission member 45, and is opened from the side wall close to the first end face to be in connection with the inflation space of the air bag body 42. By providing the air channel 451 on the transmission member 45, the inflation space in the air bag body 42 can be in fluid connection with the gas source through the air channel 451, so as to inflate or deflate the inflation space in the air bag body 42. In the connection assembly of the rotary joint for connecting the inflation space of the air bag body 42 with the external gas source, one end of the rotary joint is connected with the transmission member 45 and is in fluid connection with the air channel 451, for example, the air channel 451 penetrates to the end face of the second end of the transmission member 45, and the rotary joint is inserted into the port of the air channel 451; the other end of the rotary joint is connected with the external gas source, for example, is in fluid connection with the following pneumatic unit 5 through the pipeline.

[0088] In some embodiments, the telescopic member 4 is rotatably arranged in the casing 1, and is specifically arranged in the casing 1 through the rotation of the transmission member 45. Exemplarily, the transmission member 45 penetrates the casing 1 and is connected with the shaft hole of the casing 1, and a bearing is arranged between the transmission member 45 and the shaft hole of the casing 1, so that the transmission member 45 is selectively rotatable relative to the casing 1. Thus, the second fixed plate 44 connected with the transmission member 45 is rotatably arranged in the casing 1, and the telescopic member 4 is rotatably arranged in the casing 1. Optionally, the worm gear 31 is arranged on the transmission member 45, and thus the worm gear 31 is rotatably arranged in the casing 1.

[0089] In some embodiments, referring to Figure 2 The transmission member 45 penetrates the bottom wall of the working chamber 11 and is in transmission connection with the worm gear 31. Exemplarily, the worm gear 31 is arranged in the casing 1 and is located on the side of the working chamber 11 away from the massage member 2. The bottom wall of the working chamber 11 has a shaft hole, one end of the transmission member 45 is connected with the second fixed plate 44 in the working chamber 11, and the other end of the transmission member 45 penetrates out of the working chamber 11 through the shaft hole of the bottom wall of the working chamber 11 to be in transmission connection with the worm gear 31.

[0090] In some embodiments, the transmission member 45 passes through the worm wheel 31. Then the air passage 451 of the transmission member 45 is located at the side of the worm wheel 31 away from the massage member 2, which is convenient for fluid communication with the air source.

[0091] In preferred embodiments, the transmission member 45 and the second fixed plate 44 can be an integral structure.

[0092] In some embodiments, referring to Figures 3 to 5 , the transmission member 45 is provided with a connecting seat 452, which protrudes from the second fixed plate 44 in the direction of the first fixed plate 43. The connecting seat 452 is used to connect with the telescopic shaft 41, and the port of the air passage 451 is opened on the outer surface of the side wall of the connecting seat 452. The second end of the telescopic shaft 41 is a non-rotating end relative to the first end, and the port of the air passage 451 is spaced from the second end of the telescopic shaft 41. Exemplarily, the second end of the telescopic shaft 41 is connected to the connecting seat 452, for example, by a screw connection to the connecting seat 452; the second end of the telescopic shaft 41 is connected to the top surface of the connecting seat 452 facing the massage member 2, and the port of the air passage 451 is provided on the side surface of the connecting seat 452. Then the second end of the telescopic shaft 41 does not cover the port of the air passage 451, and the mounting seat is located in the air bag body 42, and the air passage 451 is in fluid communication with the inflation space in the air bag body 42.

[0093] In preferred embodiments, the connecting seat 452 can be a fixed structure on the transmission member 45 or an integral structure.

[0094] For the above telescopic shaft 41, referring to Figure 6 , the telescopic shaft 41 includes a first shaft segment 411 and a second shaft segment 412, which can relatively slide in the axial direction, and the first end and the second end of the air bag body 42 are respectively connected with the first shaft segment 411 and the second shaft segment 412. Exemplarily, the first shaft segment 411 and the second shaft segment 412 are connected in a sleeve connection, and the second shaft segment 412 can slide in the first shaft segment 411, so that the first shaft segment 411 and the second shaft segment 412 can relatively slide to realize extension or contraction. Among them, the first shaft segment 411 is connected with the first fixed plate 43, and the second shaft segment 412 is connected with the second fixed plate 44, so that the first shaft segment 411 and the second shaft segment 412 are respectively connected with the first end and the second end of the air bag body 42. It can be understood that when the telescopic shaft 41 drives the air bag body 42 to rotate around the axis of the telescopic shaft 41, the torque is mainly transmitted by the telescopic shaft 41 in the process of torque transmission, so that the first shaft segment 411 and the second shaft segment 412 can transmit torque to each other in the circumferential direction.

[0095] In some embodiments, the telescopic shaft 41 is hollow, specifically, the plurality of shaft segments of the telescopic shaft 41 are hollow and the hollow interiors are in communication with each other, so as to realize gas flow. For example, the first shaft segment 411 and the second shaft segment 412 are hollow and the hollow interiors are in communication with each other, so as to realize that the telescopic shaft 41 has a support filling space 413. That is, the support filling space 413 is at least partially located in the first shaft segment 411, and when the second shaft segment 412 is in the form of a cylinder, the support filling space 413 is also partially located in the second shaft segment 412. In addition, the first shaft segment 411 is provided with a gas passage hole 4111, which is specifically provided at a position close to the first end of the first shaft segment 411, so as to realize that the support filling space 413 is in fluid communication with the inflation space of the air bag body 42 when the first shaft segment 411 and the second shaft segment 412 relatively slide and expand, so that the gas in the inflation space of the air bag body 42 can flow into the support filling space 413 of the telescopic shaft 41 through the gas passage hole 4111.

[0096] It can be understood that when the first shaft segment 411 and the second shaft segment 412 relatively slide and expand, the volume of the support filling space 413 changes, resulting in that the first shaft segment 411 has air resistance when it relatively slides and expands with respect to the second shaft segment 412. By providing the gas passage hole 4111 in the first shaft segment 411 to realize that the support filling space 413 is in fluid communication with the inflation space of the air bag body 42, the gas pressure in the support filling space 413 is balanced with the gas pressure in the inflation space of the air bag body 42, the problem of air resistance of the first shaft segment 411 when it relatively slides with respect to the second shaft segment 412 is improved, the problem that the telescopic shaft 41 is not easy to be stretched or contracted is improved, and the overall telescopic member 4 can maintain stable pneumatic support effect when it is expanded.

[0097] In some other embodiments, when the first shaft segment 411 and the second shaft segment 412 are in the form of mutual sleeving, after the first shaft segment 411 is contracted with respect to the second shaft segment 412, the second end of the first shaft segment 411 can cover the second shaft segment 412 and the air channel 451 port located on the side of the connecting seat 452. Preferably, a through hole corresponding to the air channel 451 port is provided in the first shaft segment 411, so that after the first shaft segment 411 is contracted with respect to the second shaft segment 412, the port of the air channel 451 can still be in fluid communication with the inflation space of the air bag body 42 through the through hole, so as to ensure that the gas can smoothly flow into the inflation space of the air bag body 42 in the initial stage of inflation, so that the air bag body 42 is inflated, and in the final stage of exhaust, the gas can completely flow into the air channel 451 through the through hole and be discharged, so that the air bag body 42 is completely deflated, and the air bag body 42 is completely contracted in place. Optionally, the through hole penetrates to the end face of the second end of the first shaft segment 411.

[0098] In some embodiments, please refer to Figure 6The first shaft section 411 is provided with a first guide groove 4112 extending in the axial direction, and the second shaft section 412 is provided with a first guide rib 4121 extending in the axial direction, and the first guide rib 4121 is matched into the first guide groove 4112. The first guide groove 4112 is specifically arranged on the wall surface of the first shaft section 411, for example, is integrally formed on the inner wall of the first shaft section 411; and the first guide rib 4121 is specifically arranged on the wall surface of the second shaft section 412, for example, is integrally formed on the outer wall of the second shaft section 412. The first guide rib 4121 can be provided as a plurality of first guide ribs 4121, and the plurality of first guide ribs 4121 are uniformly distributed along the circumference of the second shaft section 412; correspondingly, the first guide groove 4112 is provided as a plurality of first guide grooves 4112 which are uniformly distributed along the circumference of the first shaft section 411. The first guide rib 4121 and the first guide groove 4112 are matched to form a spline joint structure, so that the first guide rib 4121 can slide in the first guide groove 4112 in a direction parallel to the first axis L, and the rotation of the first shaft section 411 relative to the second shaft section 412 is limited, thereby improving the problem that the torque transmission of the telescopic shaft 41 is invalid due to the rotation of the first shaft section 411 relative to the second shaft section 412, and realizing the torque transmission between the shaft sections.

[0099] In some embodiments, the first shaft section 411 and the second shaft section 412 are limited in the extension stroke by a limiting step in the telescopic shaft direction. Specifically, please refer to Figure 6 , the second shaft section 412 is arranged in the first shaft section 411, the inner wall of the second end of the first shaft section 411 is provided with a first limiting step 4113, and the outer circumferential surface of the first end of the second shaft section 412 is provided with a second limiting step 4122; when the air bag body 42 is stretched to drive the telescopic shaft 41 to be in the stretched limit position, the first limiting step 4113 abuts against the second limiting step 4122, so that the second shaft section 412 cannot continue to extend out of the first shaft section 411, thereby limiting the relative extension sliding distance of the first shaft section 411 and the second shaft section 412, and avoiding the problem that the second shaft section 412 and the first shaft section 411 are separated from each other. Optionally, the first guide groove 4112 extends to the first limiting step 4113.

[0100] It should be noted that, in the embodiments of the present application, the first shaft section 411 and the second shaft section 412 are relative to two shaft sections connected to the two ends of the air bag body 42, that is, for two mutually slidable telescopic shaft sections, the shaft section connected to the first end of the air bag body 42 is at least called the first shaft section 411, and the shaft section connected to the second end of the air bag body 42 is at least called the second shaft section 412. For example, Figure 6The uppermost first shaft segment 411 is used to connect with the first end of the air bag body 42; for the middle shaft segment, the middle shaft segment can also be referred to as the first shaft segment 411, wherein the first shaft segment 411 can be provided in multiple, and the multiple first shaft segments 411 are sequentially connected with each other in sliding mode by using the similar connection mode as that of the first shaft segment 411 and the second shaft segment 412; the lowermost shaft segment is used to connect with the second end of the air bag body 42, and can be referred to as the second shaft segment 412. The second shaft segment 412 can also be provided in multiple, and the multiple second shaft segments 412 are sequentially connected with each other in sliding mode by using the similar connection mode as that of the first shaft segment 411 and the second shaft segment 412.

[0101] It can be understood that the telescopic shaft 41 can be a telescopic shaft with multiple shaft segments, such as a third shaft segment, a fourth shaft segment, a fifth shaft segment, etc., so that the telescopic shaft 41 can include three or more shaft segments, and the extension length of the telescopic shaft 41 is extended. Among them, the adjacent shaft segments can be connected with each other in sliding mode by using the similar connection mode as that of the first shaft segment 411 and the second shaft segment 412, such as the telescopic shaft 41 including multiple shaft segments which are sequentially connected with each other in sleeving mode, and the two shaft segments connected with each other in sleeving mode can be provided with the matching structure of the first guide rib 4121 and the first guide groove 4112, and can be provided with the limiting matching structure of the first limiting step 4113 and the second limiting step 4122.

[0102] Moreover, in the telescopic shaft 41 provided in multiple shaft segments, the first end of the shaft segment closest to the first fixed plate 43 is connected to the first fixed plate 43, and the second end of the shaft segment closest to the second fixed plate 44 is connected to the second fixed plate 44, so that the air bag body 42 with the two ends connected to the first fixed plate 43 and the second fixed plate 44 respectively can drive the telescopic shaft 41 with multiple shaft segments to be in the maximum stroke telescoping when being pneumatically telescoped.

[0103] In some embodiments, please refer to Figures 3 to 6As shown, the telescopic shaft 41 further comprises a third shaft segment 414. The first shaft segment 411, the second shaft segment 412 and the third shaft segment 414 are sequentially sleeved, the second shaft segment 412 is sleeved on the third shaft segment 414, and the second shaft segment 412 and the third shaft segment 414 are respectively provided with a second guide groove 4123 and a second guide rib 4141 matched with each other, and the second end of the second shaft segment 412 and the first end of the third shaft segment 414 are respectively provided with a third limiting step 4124 and a fourth limiting step 4142 matched with each other. The first end of the first shaft segment 411 is connected to the first fixed plate 43, and the second end of the third shaft segment 414 is connected to the second fixed plate 44 or the connecting seat 452, that is, the telescopic shaft 41 provided with three shaft segments is connected to the second fixed plate 44 by the third shaft segment 414, so that the first end and the second end of the telescopic shaft 41 are respectively connected to the first fixed plate 43 and the second fixed plate 44. The second guide groove 4123 is similar to the first guide groove 4112; the second guide rib 4141 is similar to the first guide rib 4121; the third limiting step 4124 is similar to the first limiting step 4113; and the fourth limiting step 4142 is similar to the second limiting step 4122, which will not be described here.

[0104] In some embodiments, referring to Figures 3 to 5 As shown, in order to facilitate the sleeving assembly of the second shaft segment 412, the first shaft segment 411 is provided with an axial through hole along the first axis L, so that the second shaft segment 412 can be inserted into the first shaft segment 411 from the first end of the first shaft segment 411. The telescopic member 4 further comprises a sealing plate 48 clamped between the mounting plate 21 of the massage member 2 and the first fixed plate 43, the first end of the first shaft segment 411 is sealed by the sealing plate 48, thereby sealing the supporting and filling space 413 and preventing the inflation space in the air bag body 42 from leaking.

[0105] Preferably, the first fixed plate 43 can be integrally formed at the first end of the first shaft segment 411, and the first fixed plate 43 is provided in a flange structure at the periphery of the first end of the first shaft segment 411.

[0106] In some embodiments, referring to Figures 3 to 5 The telescopic member 4 further comprises a sealing ring 49 clamped between the sealing plate 48 and the first fixed plate 43. It can be understood that the sealing ring 49 surrounds the through opening of the first end of the first shaft segment 411, thereby enhancing the sealing effect of the through opening. Optionally, the sealing ring 49 is an elastic ring such as a rubber ring or a silica gel ring.

[0107] In some embodiments, referring to Figure 7The utility model embodiment further provides a massage system, the massage system includes above -mentioned massage movement 100 and pneumatic unit 5, pneumatic unit 5 and the air bag body 42 of massage movement 100 are in fluid communication, and pneumatic unit 5 is used for the air supply of air bag body 42 and / or suction gas in air bag body 42. When pneumatic unit 5 supplies air to air bag body 42, air bag body 42 inflates and expands, and pushes massage member 2 out; when pneumatic unit 5 sucks the gas in air bag body 42, air bag body 42 deflates and shrinks, and drives massage member 2 to retract. It can be understood that air bag body 42 can also be communicated with the atmosphere to deflate.

[0108] In some embodiments, referring to Figure 7 Pneumatic unit 5 includes gas source device 51, and gas source device 51 is in fluid communication with air bag body 42. Exemplarily, gas source device 51 includes but is not limited to air pump, air compressor and the like. Gas source device 51 can be a reversible air pump, which can supply air to air bag body 42 from a single air port, or suck the gas in air bag body 42 in reverse.

[0109] Alternatively, gas source device 51 can be provided with negative pressure air inlet 511 and positive pressure air outlet 512, negative pressure air inlet 511 is used for gas inflow, and positive pressure air outlet 512 is used for compressed gas outflow. When gas source device 51 works, gas is sucked from negative pressure air inlet 511, and then compressed gas is discharged from positive pressure air outlet 512 to supply air to air bag body 42. When gas source device 51 only supplies air to air bag body 42, negative pressure air inlet 511 of gas source device 51 can be in fluid communication with the external environment, for example, directly connected with the atmosphere, and positive pressure air outlet 512 of gas source device 51 is in fluid communication with air bag body 42, or negative pressure air inlet 511 of gas source device 51 can be in communication with the deflation port of air bag body 42 to accelerate the deflation of air bag body 42 by sucking gas. When air bag body 42 is supplied with air through positive pressure air outlet 512, the extension response speed of telescopic member 4 is improved.

[0110] In some embodiments, referring to Figure 7 Pneumatic unit 5 further includes fluid distribution device 52, and gas source device 51 is in fluid communication with air bag body 42 through fluid distribution device 52, forming a pneumatic system. Fluid distribution device 52 is used to control the on-off of the deflation gas path of air bag body 42, and control the on-off of the inflation gas path between air bag body 42 and gas source device 51.

[0111] In some embodiments, referring to Figure 7The fluid distribution device 52 is provided with a distribution intake port 521, a distribution charging port 522 and a distribution exhaust port 523. The fluid distribution device 52 has a charging state in which the distribution intake port 521 is in communication with the distribution charging port 522 and the distribution exhaust port 523 is closed, an exhaust state in which the distribution intake port 521 is closed and the distribution charging port 522 is in communication with the distribution exhaust port 523, and a holding state in which the distribution intake port 521 and the distribution exhaust port 523 are closed. The positive pressure outlet port 512 of the gas source device 51 is in fluid communication with the distribution intake port 521 of the fluid distribution device 52, and the distribution charging port 522 is in fluid communication with the air bag body 42. For example, the distribution intake port 521 is in fluid communication with the positive pressure outlet port 512 through a pipeline, the distribution charging port 522 is in fluid communication with the air bag body 42 through a pipeline, and the distribution exhaust port 523 is in fluid communication with the atmosphere. When the distribution intake port 521 is in communication with the distribution charging port 522 and the distribution exhaust port 523 is closed, the air bag body 42 is in fluid communication with the gas source device 51, and the compressed gas in the gas source device 51 is introduced into the air bag body 42, i.e. the fluid distribution device 52 is in a charging state at this time. When the distribution intake port 521 is closed and the distribution charging port 522 is in communication with the distribution exhaust port 523, the air bag body 42 is in fluid communication with the atmosphere, and the high-pressure gas in the air bag body 42 is discharged into the atmosphere, i.e. the fluid distribution device 52 is in an exhaust state at this time. When the distribution intake port 521 is closed and the distribution exhaust port 523 is closed, the air bag body 42 is sealed from the gas source device 51 and the atmosphere, i.e. the fluid distribution device 52 is in a holding state at this time. The fluid distribution device 52 can be selected but is not limited to a gas valve such as a solenoid valve or an SMA (Shape Memory Alloy) valve, including a three-position three-way solenoid valve.

[0112] In other embodiments, the distribution exhaust port 523 of the fluid distribution device 52 is in fluid communication with the negative pressure intake port 511 of the gas source device 51. For example, the distribution exhaust port 523 and the negative pressure intake port 511 are in fluid communication through a pipeline, i.e. the gas in the air bag body 42 is sucked through the gas source device 51 to achieve deflation. Deflating the air bag body 42 by sucking the gas in the air bag body 42 increases the degree of deflation of the air bag body 42, promotes the deflation of the air bag body 42, and makes the deflation of the air bag body 42 more complete and in a shorter time. That is, the air bag body 42 can be quickly and completely deflated to reset, so that the massage member 2 can be quickly and completely retracted to ensure that the massage member 2 quickly retreats from the extended position to the retracted position and ensures the travel of the next massage work, so that the massage starts faster and enhances the massage experience.

[0113] In some embodiments, the number of fluid distribution devices 52 is plural, the number of air bag bodies 42 is plural, the plural fluid distribution devices 52 are respectively used to control the opening and closing of the deflation air paths of the plural air bag bodies 42, and the plural fluid distribution devices 52 are respectively used to control the opening and closing of the inflation air paths between the plural air bag bodies 42 and the air source device 51. The plural fluid distribution devices 52 and the plural air bag bodies 42 can share the same air source device 51, so that a single pneumatic unit 5 can control the inflation and deflation of the plural air bag bodies 42.

[0114] In some embodiments, the distribution air outlet 521 of the plural fluid distribution devices 52 is in fluid communication with the positive pressure air outlet 512 of the same air source device 51. That is, the plural fluid distribution devices 52 share the same air source device 51, which is conducive to reducing the production cost of the massage movement 100. In addition, the distribution air outlet 523 of the plural fluid distribution devices 52 can be in fluid communication with the negative pressure air inlet 511 of the same air source device 51, so as to realize unified air exhaust.

[0115] In some embodiments, please refer to Figure 7 The pneumatic unit 5 further comprises an air tank 53, which is in fluid communication between the positive pressure air outlet 512 of the air source device 51 and the distribution air inlet 521 of the fluid distribution device 52. The air tank 53 can be a metal tank, a plastic tank, etc., and can contain high-pressure gas. The air tank 53 can store high-pressure gas, which is conducive to improving the inflation expansion stroke and inflation response speed of the air bag body 42.

[0116] In some embodiments, the pneumatic unit 5 comprises a low-pressure generator 54 connected between the distribution air outlet 523 of the fluid distribution device 52 and the negative pressure air inlet 511 of the air source device 51, so as to realize negative pressure exhaust of the air bag body 42 and enhance the deflation effect of the air bag body 42.

[0117] For the above-mentioned low-pressure generator 54, please refer to Figure 8, the low pressure generator 54 is provided with a low pressure port 5411, a first opening 5412 and a second opening 5413, the low pressure port 5411 is in fluid communication between the first opening 5412 and the second opening 5413, and the low pressure port 5411 is used to generate negative pressure when the gas flows from the first opening 5412 to the second opening 5413. That is, the air pressure at the low pressure port 5411 is lower than the atmospheric pressure. Negative pressure refers to its true air pressure being lower than the standard atmospheric pressure, that is, lower than 101.325 kilopascals, and negative pressure is usually expressed as its true air pressure minus the standard atmospheric pressure, for example, the negative pressure can be -40 kilopascals, -20 kilopascals, -10 kilopascals, etc. When the fluid distribution device 52 controls the deflation of the air bag body 42, the low pressure port 5411 is brought into fluid communication with the air bag body 42 to achieve the deflation of the air bag body 42. By bringing the low pressure port 5411 into fluid communication with the air bag body 42, the negative pressure generated by the low pressure port 5411 when the gas flows from the first opening 5412 to the second opening 5413 will increase the deflation speed of the air bag body 42, increase the deflation degree of the air bag body 42, and make the air bag body 42 deflate more completely and complete the deflation in a shorter time.

[0118] Exemplarily, the low pressure generator 54 includes a generator body 541, which can be tubular, and the openings at both ends thereof are the first opening 5412 and the second opening 5413 respectively, and the low pressure port 5411 can be formed through the wall of the generator body 541. Thus, the gas flowing from the first opening 5412 to the second opening 5413 will flow through the low pressure port 5411, and the flow rate of the gas flowing from the first opening 5412 to the second opening 5413 is greater than that of the gas in the low pressure port 5411, and the faster the flow rate, the lower the pressure. Therefore, the air pressure of the gas flowing from the first opening 5412 to the second opening 5413 is lower than that of the gas in the low pressure port 5411, so that the air pressure at the low pressure port 5411 is reduced and lower than the atmospheric pressure, that is, negative pressure is generated.

[0119] In some embodiments, referring to Figure 8 , the low pressure port 5411 is in fluid communication with the distribution exhaust port 523 of the fluid distribution device 52, the first opening 5412 is in fluid communication with the atmosphere, and the second opening 5413 is in fluid communication with the negative pressure intake port 511 of the gas source device 51. Exemplarily, the distribution exhaust port 523 and the low pressure port 5411 are in fluid communication through a pipeline; when the fluid distribution device 52 is in the exhaust state, the distribution inflation port 522 is in fluid communication with the distribution exhaust port 523, and the gas source device 51 is in the suction intake state, so that the low pressure port 5411 generates low pressure, thereby the air bag body 42 is negatively deflated by the low pressure generator 54, and the deflation speed of the air bag body 42 is increased.

[0120] In some embodiments, the plurality of fluid dispensing devices 52 have their dispensing exhaust ports 523 in fluid communication with the low pressure port 5411 of the same low pressure generator 54. That is, the plurality of fluid dispensing devices 52 share a single low pressure generator 54, which advantageously reduces the production cost of the massage movement 100.

[0121] In some embodiments, referring to Figure 8 As shown, the generator body 541 is provided with a low pressure generation chamber 5414, which is in communication between the first opening 5412 and the second opening 5413. The low pressure generation chamber 5414 includes a first contraction chamber 54141, which is in fluid communication with the low pressure port 5411 at one end away from the first opening 5412. The first contraction chamber 54141 is a chamber with a cross-sectional area that gradually decreases along the direction of fluid flow, which can be in the shape of a truncated cone. When the gas flows from the first opening 5412 to the second opening 5413 and passes through the first contraction chamber 54141, the cross-sectional area of the chamber allowing the gas to pass through gradually decreases, and the flow rate of the gas increases, so that the gas pressure decreases when the gas passes through the first contraction chamber 54141, thereby enhancing the negative pressure at the low pressure port 5411. It can be understood that the faster the gas flows through the first contraction chamber 54141, the greater the negative pressure formed at the low pressure port 5411.

[0122] In some embodiments, referring to Figure 8 As shown, the low pressure generation chamber 5414 further includes a diffusion chamber 54142, which is in fluid communication with the one end of the first contraction chamber 54141 away from the first opening 5412, and the cross-sectional area of the diffusion chamber 54142 is greater than that of the first contraction chamber 54141. Exemplarily, the diffusion chamber 54142 is in the shape of a cylinder, the one end of the first contraction chamber 54141 away from the first opening 5412 is in fluid communication with the diffusion chamber 54142, and the inner diameter of the diffusion chamber 54142 is greater than that of the port of the one end of the first contraction chamber 54141 in fluid communication with the diffusion chamber 54142. When the gas flows from the first contraction chamber 54141 to the diffusion chamber 54142, the cross-sectional area of the chamber allowing the gas to pass through suddenly increases, so that the gas is difficult to expand to the entire diffusion chamber 54142; and the flow rate of the gas is relatively large, and the gas is sprayed in the form of a jet to the second opening 5413, thereby reducing the gas pressure in the diffusion chamber 54142. In addition, in the embodiment of the utility model, the low pressure port 5411 is in fluid communication with the first contraction chamber 54141 through the diffusion chamber 54142, which can enhance the negative pressure at the low pressure port 5411 compared to the case where the low pressure port 5411 is directly in communication with the inner wall of the one end of the first contraction chamber 54141 away from the first opening 5412.

[0123] In further embodiments, referring to Figure 8As shown, the generator body 541 further comprises a converging cylinder portion 5415 and a nozzle 5416. The converging cylinder portion 5415 is in the shape of a conical cylinder, and the converging cylinder portion 5415 is in fluid communication with the first opening 5412 at one end with a larger opening, and the other end of the converging cylinder portion 5415 is directed towards the second opening 5413, and the internal space of the converging cylinder portion 5415 defines a first converging chamber 54141. The nozzle 5416 is in the shape of a cylindrical cylinder, and one end of the nozzle 5416 is in fluid communication with the other end of the converging cylinder portion 5415 with a smaller opening, and the other end of the nozzle 5416 is directed towards the second opening 5413, so that the gas flowing out of the converging cylinder portion 5415 is guided and constrained by the nozzle 5416 to form a jet gas flow. The diffusion chamber 54142 is defined between the outer wall of the converging cylinder portion 5415 and the nozzle 5416 and the inner wall of the generator body 541, so that the rapid gas flow ejected by the nozzle 5416 can more easily cause a negative pressure effect in the diffusion chamber 54142, further enhancing the negative pressure at the low-pressure port 5411.

[0124] In some embodiments, referring to Figure 8 As shown, the low-pressure generating chamber 5414 further comprises a second converging chamber 54143 and an expansion chamber 54144, the second converging chamber 54143 is in fluid communication with one end of the diffusion chamber 54142 away from the first opening 5412, and the expansion chamber 54144 is in fluid communication with one end of the second converging chamber 54143 away from the first opening 5412. The second converging chamber 54143 is a chamber with a cross-sectional area that gradually decreases along the direction of fluid flow, which can be in the shape of a truncated cone. The expansion chamber 54144 is a chamber with a cross-sectional area that gradually increases along the direction of fluid flow, which can be in the shape of a truncated cone. It can be understood that the second converging chamber 54143 and the expansion chamber 54144 form a Laval tube to accelerate the gas flowing out of the diffusion chamber 54142, increase the flow rate of the gas flowing through the low-pressure generator 54, and further enhance the negative pressure at the low-pressure port 5411.

[0125] In some embodiments, referring to Figure 8 As shown, the negative pressure air inlet 511 is in fluid communication with the second opening 5413, for example, through a pipeline. In this way, the low-pressure driving of the low-pressure generator 54 and the gas supply for the airbag body 42 are realized by a single gas source device 51, without the need to set up an additional air pump, reducing the number of gas source devices 51, reducing production cost, and reducing energy consumption. In this embodiment, the first opening 5412 can be in fluid communication with the atmospheric environment.

[0126] When the massage movement 100 of the utility model embodiment works, the gas source device 51 starts.

[0127] When the pneumatic unit 5 supplies air to the air bag body 42: the fluid distribution device 52 makes the distribution air inlet 521 and the distribution inflation outlet 522 conductive and the distribution exhaust outlet 523 closed, at this time the fluid distribution device 52 is in the inflation state, the air bag body 42 is in fluid communication with the positive pressure outlet 512 of the air source device 51, and the air bag body 42 is inflated and stretched.

[0128] When the massage member 2 performs massage: when the massage member 2 moves to the extended position, the distribution air inlet 521 and the distribution exhaust outlet 523 are both closed, at this time the air bag body 42 cannot be inflated and deflated, that is, the air bag body 42 is pressure maintained, and the massage member 2 is maintained in the extended position. At this time, the motor 33 of the driving device 3 is started, and drives the extension member 4 to rotate through the worm wheel 31 and the worm 32, the extension member 4 drives the torque, and drives the massage member 2 to rotate for massage.

[0129] When the air bag body 42 is deflated, and the pneumatic unit 5 sucks the gas in the air bag body 42: the fluid distribution device 52 makes the distribution air inlet 521 closed and the distribution inflation outlet 522 and the distribution exhaust outlet 523 conductive, at this time the fluid distribution device 52 is in the exhaust state, the air bag body 42 is in fluid communication with the negative pressure air inlet 511 of the air source device 51, or the low pressure port 5411 of the low pressure generator 54, and the air bag body 42 is deflated and contracted; when the air bag body 42 is deflated and contracted, the telescopic shaft 41 is simultaneously retracted, that is, the extension member 4 is retracted, and the massage member 2 is moved to the retracted position.

[0130] When the massage member 2 is stored: when the massage member 2 moves to the retracted position, the distribution air inlet 521 is closed, at this time the air bag body 42 cannot be inflated and deflated, that is, the air bag body 42 is normal, and the massage member 2 is maintained in the retracted position.

[0131] The massage core 100 of the embodiment of the utility model can be applied to massage seats, neck massagers, waist massagers, eye massagers, foot massagers and car seats.
