[0053] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.

[0054] Please refer to Figure 1 And Figure 2 The utility model embodiment provides a massage equipment 100, massage equipment 100 includes massage subassembly and telescopic air bag 3. Massage subassembly includes massage member 4 and drive arrangement 2. Drive arrangement 2 is transmission connection with massage member 4, and drive arrangement 2 is used to drive massage member 4 rotation. Telescopic air bag 3 is connected with massage subassembly, and telescopic air bag 3 is used at least to drive massage subassembly to move from the retracted position to the extended position switching.

[0055] In the utility model embodiment, the first axis L is taken as the rotation axis of massage member 4 for example to be described. Specifically, telescopic air bag 3 is fixedly connected with massage subassembly, and telescopic air bag 3 is used to drive massage subassembly to move along the direction parallel to the first axis L to move to the extended position and the retracted position, and the extended position is specifically the working position of massage subassembly, and the retracted position is specifically the storage position of massage subassembly. Among them, the extended position and the retracted position are two positions of massage subassembly along the direction parallel to the first axis L, when massage subassembly is located in the extended position, massage subassembly is moved to the retracted position by deflating and contracting telescopic air bag 3, and when massage subassembly is located in the retracted position, massage subassembly is moved to the extended position by inflating and expanding telescopic air bag 3.

[0056] The telescopic air bag 3 can drive the massage member 4 to switch between the extended position and the retracted position quickly and efficiently through high response inflation and deflation speed, and provide the massage member 4 with a reliable and cushioned extrusion massage support in the extended position. The driving device 2 can drive the massage member 4 to rotate around the first axis L and move in a direction parallel to the first axis L. The massage member 4 is driven to rotate by the driving device 2 to achieve rolling kneading massage, and the rotation speed and direction of the massage member 4 can be controlled during the massage to achieve different massage effects.

[0057] In this embodiment, the massage member 4 is driven to rotate by the driving device 2 to achieve rolling kneading massage, which is beneficial to improve the massage speed and improve the massage intensity.

[0058] In addition, the telescopic air bag 3 is specifically an air bag that can be inflated to expand and deflated to contract and fold, including an air bag that can have a single-layer or multi-layer bag body. The use of the telescopic air bag 3 can improve the massage stroke, improve the massage intensity, and improve the problem of weak intensity when massage is achieved through the air bag. Moreover, the telescopic air bag 3 does not need to rotate synchronously with the massage member 4, which facilitates the fluid communication between the telescopic air bag 3 and the gas source, such as the fluid communication with the following pneumatic unit.

[0059] In some embodiments, referring to Figure 1 and Figure 2 , the massage device 100 further includes a housing 1, one end of the telescopic air bag 3 is connected to the massage assembly, and the other end of the telescopic air bag 3 is connected to the housing 1. The housing 1 is used to be mounted on a mounting base, such as a seat, and the driving device 2 drives the massage member 4 to rotate and move relative to the mounting base to achieve massage.

[0060] In some embodiments, referring to Figure 1 and Figure 2 , the massage assembly is slidably arranged in the housing 1. It can be understood that the massage assembly is used to move in a direction parallel to the first axis L relative to the housing 1. Exemplarily, the housing 1 is provided with a working chamber 11, and the massage assembly is slidably arranged in the working chamber 11. Thus, the massage assembly can slide relative to the housing 1. Among them, the axis of the working chamber 11 is parallel to the first axis L, so that the sliding direction of the massage assembly relative to the housing 1 is parallel to the first axis L.

[0061] In some embodiments, the housing 1 is provided with a first guide structure 12, and the driving device 2 is provided with a second guide structure 21, the second guide structure 21 is slidably connected with the first guide structure 12, so that the driving device 2 is slidably arranged on the housing 1, and the driving device 2 can drive the massage member 4 to rotate relative to the housing 1. Exemplarily, referring to Figure 1 and Figure 2The first guide structure 12 comprises a guide groove 121, and the second guide structure 21 comprises a guide rib 211. The guide groove 121 extends along the direction parallel to the first axis L, and the guide rib 211 is fitted into the guide groove 121, so that the guide rib 211 can slide in the guide groove 121. Optionally, the casing 1 is provided with a plurality of first guide structures 12, which are arranged along the circumference of the first axis L at intervals. The drive is correspondingly provided with a plurality of second guide structures 21, which are in one-to-one correspondence with the plurality of first guide structures 12 and are in sliding connection with the plurality of first guide structures 12. Optionally, the second guide structure 21 can also comprise a guide groove 121, and the first guide structure 12 can also comprise a guide rib 211. It can be understood that the plurality of second guide structures 21 are in one-to-one correspondence with the plurality of first guide structures 12 and are in sliding connection with the plurality of first guide structures 12. Alternatively, the drive device 2 can be slidably arranged in the casing 1, that is, the casing 1 does not need to be provided with the working chamber 11 in the embodiment.

[0062] In some embodiments, referring to Figure 1 and Figure 2 , the first guide structure 12 is arranged on the inner wall of the working chamber 11, the drive device 2 comprises a housing 22, the output end of the drive device 2 is in transmission connection with the massage member 4, and the massage member 4 rotates relative to the housing 22 when the massage member 4 is driven to rotate. The second guide structure 21 is arranged on the outer circumferential surface of the housing 22 of the drive device 2 around the first axis L. When the drive device 2 is slidably arranged in the working chamber 11, the drive device 2 can be slidably arranged in the casing 1 along the direction parallel to the first axis L. At this time, the number of the first guide structure 12 and the number of the second guide structure 21 can each be one.

[0063] In some embodiments, the massage assembly at least partially extends out of the working chamber 11 in the extended position, such as the top massage member 4 extending out of the working chamber 11 or the entire massage assembly extending out of the working chamber 11. The massage assembly at least partially locates in the working chamber 11 in the retracted position, such as the bottom drive device 2 being retracted into the working chamber 11 or the entire massage assembly being retracted into the working chamber 11. Exemplarily, one end of the telescopic air bag 3 is connected to the casing 1 in the working chamber 11. When the telescopic air bag 3 is completely deflated and contracted, the telescopic air bag 3 is completely accommodated in the working chamber 11, and at this time, the massage assembly is at least partially located in the working chamber 11. When the telescopic air bag 3 is completely inflated and expanded, the distance between the telescopic air bag 3 and the opening of the working chamber 11 is less than the thickness of the massage assembly along the direction parallel to the first axis L, and at this time, the massage assembly extends out of the working chamber 11. When the telescopic air bag 3 is completely inflated and expanded, the telescopic air bag 3 extends out of the working chamber 11, and at this time, the massage assembly is completely located outside the working chamber 11. By driving the massage assembly to switch between the extended position and the retracted position through the telescopic air bag 3, the massage assembly can be accommodated when the massage assembly is not working, thereby reducing the discomfort to the user. When the massage assembly is working, the massage assembly can be extended to enter the working position.

[0064] In some embodiments, the telescopic air bag 3 is always accommodated in the working chamber 11. That is, when the telescopic air bag 3 is fully inflated and stretched, the telescopic air bag 3 is still fully accommodated in the working chamber 11, and the driving device 2 is partially accommodated in the working chamber 11. The driving device 2 is always in sliding connection with the casing 1, which improves the problem that the driving device 2 cannot be returned due to disengagement from the casing 1.

[0065] In some embodiments, referring to Figure 2 , the massage device 100 further comprises an elastic reset member 5 for elastically urging the massage assembly to switch from the extended position to the retracted position.

[0066] Illustratively, the elastic member is a tension spring, one end of which is connected to the casing 1, and the other end of which is connected to the driving device 2. When the telescopic air bag 3 drives the massage assembly to move to the extended position, the tension spring is stretched; when the telescopic air bag 3 is deflated, the elastic force of the tension spring urges the driving device 2 to switch from the extended position to the retracted position and compresses the telescopic air bag 3, accelerating the deflation and contraction of the telescopic air bag 3. Alternatively, one end of the elastic reset member 5 is connected to the first guide structure 12, and the other end of the elastic reset member 5 is connected to the second guide structure 21, for example, one end of the elastic reset member 5 is connected to the casing 1 in the guide groove 121, and the other end of the elastic reset member 5 is connected to the guide rib 211 on the driving device 2.

[0067] Further optionally, the telescopic air bag 3 and the massage assembly can be in abutment or fixed connection, such as abutting the bottom of the driving device 2 without fixed connection. When the telescopic air bag 3 is inflated and expanded, it pushes the massage assembly to extend; and when the telescopic air bag 3 is deflated and contracted, the massage assembly can be urged to reset by the elastic reset member 5, and / or reset by the telescopic air bag 3 fixedly connected to the driving device 2 through contraction.

[0068] For the above massage member 4, referring to Figure 3 and Figure 4 , the massage member 4 comprises a rotating disc 41 and a massage head 42, the massage head 42 is arranged on the side of the rotating disc 41 away from the driving device 2, the massage head 42 is spaced apart from the first axis L, and the driving device 2 is in transmission connection with the rotating disc 41, the driving device 2 drives the rotating disc 41 to rotate, and the rotating rotating disc 41 drives the massage head 42 arranged thereon to rotate. When the rotating disc 41 rotates around the first axis L, the movement of the massage head 42 around the first axis L, in turn, realizes kneading massage. Optionally, the rotating disc 41 is detachably mounted on the driving device 2, for example, by screws on the output shaft 24 of the driving device 2. Optionally, the massage head 42 is detachably mounted on the rotating disc 41, for example, by screws on the rotating disc 41.

[0069] In some embodiments, referring to Figure 3 and Figure 4The number of the massage heads 42 is multiple, and the multiple massage heads 42 are arranged on the rotating disc 41 in a circumferential direction of the first axis L. That is, the multiple massage heads 42 are arranged around the first axis L. Optionally, the number of the massage heads 42 is three. Optionally, the massage heads 42 are hemispherical.

[0070] In some embodiments, referring to Figure 3 and Figure 4 , the massage heads 42 are rotatably arranged on the rotating disc 41. When the rotating disc 41 drives the massage heads 42 to move around the first axis L, the massage heads 42 can roll on the object to be pressed, thereby reducing the frictional resistance. Exemplarily, the massage member 4 further comprises a bearing 43 rotatably arranged on the rotating disc 41, and the massage heads 42 are mounted on the bearing 43. Optionally, the rotation axis of the massage heads 42 relative to the rotating disc 41 is parallel to the first axis L. Optionally, the rotation axis of the massage heads 42 relative to the rotating disc 41 is perpendicular to the first axis L.

[0071] For the above-mentioned driving device 2, in some embodiments, the driving device 2 comprises an air engine, and the air engine is in driving connection with the massage member 4. Exemplarily, referring to Figures 3 to 5 , the air engine comprises a housing 22, a nutating disc 23 and an output shaft 24. The nutating disc 23 is swingably arranged in the housing 22, and the output shaft 24 is in driving connection with the nutating disc 23. The nutating disc 23 is configured to swing in the housing 22 to drive the output shaft 24 to rotate around the first axis L. The massage member 4 is connected with the output shaft 24, thereby driving the massage member 4 to rotate around the first axis L. Optionally, the massage member 4 is connected with the output shaft 24 by spline connection or fixed connection.

[0072] In some embodiments, referring to Figures 3 to 5 , the housing 22 is provided with a nutating cavity 221 and two spherical grooves 222, and the two spherical grooves 222 are oppositely arranged and in communication with the nutating cavity 221. The nutating disc 23 comprises a spherical portion 232 and a disc portion 233. The opposite sides of the spherical portion 232 are arranged in the two spherical grooves 222, respectively, and the disc portion 233 is arranged on the spherical portion 232 to arrange the nutating disc 23 in the housing 22. The nutating disc 23 is provided with a radial extending separation groove 231 on the outer circumferential side, and the housing 22 is provided with a separation wall 223 in the nutating cavity 221. One end of the separation wall 223 is arranged in the separation groove 231 to limit the rotation of the nutating disc 23 around the first axis L. Thus, the nutating disc 23 can swing around the first axis L in the nutating cavity 221.

[0073] In some embodiments, the output shaft 24 is a crankshaft, a first end of the crankshaft extends along the first axis L, and a second end of the crankshaft extends along the axis of the nutating disc 23. When the nutating disc 23 nutates around the first axis L, the axis of the nutating disc 23 nutates around the first axis L at the same time, and in turn drives the second end of the crankshaft to nutate around the first axis L. Since the first end and the second end of the crankshaft are fixedly connected, the crankshaft as a whole rotates around the first axis L, i.e. the first end of the crankshaft rotates around the first axis L.

[0074] In some embodiments, referring to Figures 3 to 5 , the housing 22 is provided with a nutating air inlet 224 and a nutating air outlet 225, one end of the partition wall 223 is connected to the inner wall of the nutating cavity 221 between the nutating air inlet 224 and the nutating air outlet 225, the nutating air inlet 224 and the nutating air outlet 225 are located on both sides of the partition wall 223, the other end of the partition wall 223 is in sealing contact with the spherical portion 232, and the two ends of the partition wall 223 in the direction parallel to the first axis L abut the inner wall of the nutating cavity 221 respectively, so as to divide the nutating cavity 221 into a "C" shape; the outer circumferential surface of the nutating disc 23 is in sealing contact with the inner wall of the nutating cavity 221, so as to divide the nutating cavity 221 into two sub-chambers 2211. It can be understood that the two sub-chambers 2211 are both in the shape of "C". Among them, the disc portion 233 is in the shape of a cone, and one generatrix of the disc portion 233 is in line contact with the inner wall of the nutating cavity 221, so as to divide the sub-chamber 2211 in the shape of "C" into two semicircular half-chambers 2212. Among them, the partition groove 231 can extend to the spherical portion 232, i.e. the partition wall 223 is partially arranged in the partition groove 231 of the spherical portion 232.

[0075] When the nutating disc 23 nutates around the first axis L, the intersection line between the disc portion 233 and the inner wall of the nutating cavity 221 rotates along the first axis L, so that the volumes of the two half-chambers 2212 change at the same time, and the sum of the volumes of the two half-chambers 2212 remains unchanged. Since the nutating air inlet 224 and the nutating air outlet 225 are respectively in fluid communication with the two half-chambers 2212, when the nutating air inlet 224 is in the state of air intake and / or the nutating air outlet 225 is in the state of air exhaust, the nutating disc 23 is driven to nutate around the first axis L. Among them, the spherical portion 232 is in sealing contact with the inner wall of the two spherical grooves 222, so as to improve the problem of air leakage between the two semicircular half-chambers 2212 through the gap between the spherical portion 232 and the inner wall of the spherical groove 222.

[0076] In some embodiments, referring to Figures 3 to 5, the disc part 233 is in the shape of two cones connected by a bottom surface. The disc part 233 is in line contact with the opposite two inner walls of the nutating cavity 221 through two busbars, respectively, so that the two "C"-shaped sub-chambers 2211 are each divided into two fan-shaped half-chambers 2212. When the nutating air inlet 224 is inhaled and / or the nutating air outlet 225 is exhausted, the gas can flow in the two sub-chambers 2211 at the same time and drive the nutating disc 23 to swing, thereby improving the speed of the nutating disc 23 and increasing the torque output by the nutating disc 23 to the output shaft 24.

[0077] In some embodiments, referring to Figure 4 , the side of the shell 22 facing the massage member 4 is provided with a sliding groove 226 extending annularly along the circumference of the first axis L, which is used for sliding connection with the protrusion on the massage member 4. This enhances the stability of the rotation of the massage member 4 relative to the driving device 2, supports the massage member 4, and improves the problem of tilting of the massage member 4 relative to the driving device 2 when subjected to external force.

[0078] In some embodiments, the driving device 2 comprises a disc motor in transmission connection with the massage member 4. Exemplarily, the shell 22 of the disc motor is connected to one end of the stretchable air bag 3, the output shaft of the disc motor is connected to the massage member 4, and the axis of the output shaft of the disc motor coincides with the first axis L, thereby driving the massage member 4 to rotate around the first axis L relative to the casing 1.

[0079] In some embodiments, the driving device 2 comprises a speed reduction driving device, referring to Figure 6 , the driving device 2 comprises a shell 22, a worm gear 25, a worm 26, and a motor 27. The shell 22 is connected to one end of the stretchable air bag 3, the worm gear 25 is rotatably arranged in the shell 22 around the first axis L, the worm 26 is rotatably arranged in the shell 22, the worm 26 is in mesh with the worm gear 25, and the motor 27 is in transmission connection with the worm 26. The worm gear 25 is in transmission connection with the massage member 4, for example, the driving device 2 further comprises an output shaft 24, one end of the output shaft 24 is connected to the worm gear 25, and the other end of the output shaft 24 penetrates the shell 22 and is connected to the massage member 4. The motor 27 is used to drive the worm 26 to rotate, thereby driving the worm gear 25 and the massage member 4 to rotate around the first axis L.

[0080] By driving the worm gear 25 to rotate through the worm 26, the effect of a speed reducer is achieved, i.e., the rotation speed of the massage member 4 is reduced and the torque of the massage member 4 is increased, which can improve the problem of poor massage effect caused by too fast rotation of the massage member 4 and the problem of the massage member 4 being unable to rotate caused by the resistance being greater than the output torque of the motor 27.

[0081] Furthermore, the cooperation of the worm gear 25, the worm 26 and the motor 27 can also shorten the thickness of the driving device 2 along the direction parallel to the first axis L, and further shorten the thickness of the massage apparatus 100 along the direction parallel to the first axis L.

[0082] In some embodiments, the number of the casing 1, the massage member 4 and the driving device 2 is multiple, and the multiple driving devices 2 drive the respective worms 26 to rotate through the same motor 27. Reducing the number of the motor 27 can reduce the cost of the massage apparatus 100, and is beneficial to the synchronization of the rotation speeds of the multiple massage members 4.

[0083] In some embodiments, referring to Figure 6 , the casing 1 is provided with a working chamber 11 and an actuating chamber 13, the massage assembly is slidingly arranged in the working chamber 11, and the stretchable air bag 3 is arranged in the actuating chamber 13. The stretchable air bag 3 is in driving connection with the massage assembly through a transmission member 28 penetrating the working chamber 11 and the actuating chamber 13. Specifically, the stretchable air bag 3 is in action connection with the bottom end of the transmission member 28, and the top end of the transmission member 28 is in action connection with the massage assembly.

[0084] When the stretchable air bag 3 is inflated and stretched, the transmission member 28 is pushed, so that the massage assembly moves to the extended position. When the stretchable air bag 3 is deflated and contracted, the massage assembly is reset under the action of the elastic reset member 5 and / or the transmission member 28 is pulled back by the stretchable air bag 3, so that the massage assembly moves to the retracted position. It can be understood that the transmission member 28 is slidingly arranged in the casing 1, for example, penetrating the wall body between the working chamber 11 and the actuating chamber 13, which is beneficial to limiting the movement of the massage assembly along the direction parallel to the first axis L and reducing the shaking of the massage assembly.

[0085] In some embodiments, the transmission member 28 is a telescopic transmission shaft. One end of the telescopic transmission shaft is connected to the casing 1, the other end of the telescopic transmission shaft is connected to the massage assembly, and the stretchable air bag 3 is connected to the telescopic transmission shaft and drives the telescopic transmission shaft to stretch and contract.

[0086] In some embodiments, referring to Figure 6 , the two ends of the elastic reset member 5 are respectively in action connection with the inner wall of the actuating chamber 13 and the transmission member. Specifically, the transmission member 28 includes a transmission plate 281 and a transmission shaft, the transmission plate 281 is arranged between the elastic reset member 5 and the stretchable air bag 3, one end of the elastic reset member 5 is supported on the side of the transmission plate 281 away from the stretchable air bag 3, the stretchable air bag 3 is abutted or fixed to the other side of the transmission plate 281 away from the elastic reset member 5, and the other end of the elastic reset member 5 is supported on the inner wall of the actuating chamber 13 away from the driving device 2, one end of the transmission shaft is connected to the transmission plate 281 and the other end is connected to the massage assembly, so that the elastic reset member 5 can elastically act on the transmission plate 281 and elastically promote the massage assembly to switch and reset from the extended position to the retracted position.

[0087] In some embodiments, please refer to Figure 6 , one end of the telescopic air bag 3 is supported on the inner wall of the actuating chamber 13 facing the driving device 2, and the other end of the telescopic air bag 3 is supported on the side of the transmission plate 281 away from the driving device 2. Thus, the telescopic air bag 3 cooperates with the elastic return member 5 to drive the telescopic air bag 3 and the elastic return member 5 and the transmission member 28 into transmission connection without the need for fixing by screws, adhesives or the like, thereby reducing the production cost of the massage device 100.

[0088] For the telescopic air bag 3 described above, the telescopic air bag 3 is made of a flexible material, such as rubber, silicone, plastic or the like, including TPU, so that the telescopic air bag 3 can be inflated and expanded and deflated and contracted. In some embodiments, please refer to Figure 2 , the telescopic air bag 3 includes a plurality of bag bodies 31 arranged in parallel to the first axis L, thereby increasing the telescopic length of the telescopic air bag 3 in parallel to the first axis L. Optionally, the bag body 31 can be of any shape, including circular, square, polygonal or the like.

[0089] In some embodiments, please refer to Figure 7 , the massage device 100 further includes a pneumatic unit 6, the pneumatic unit 6 is in fluid communication with the telescopic air bag 3, and the pneumatic unit 6 is used to supply air to the telescopic air bag 3 and / or to suck the air in the telescopic air bag 3. When the pneumatic unit 6 supplies air to the telescopic air bag 3, the telescopic air bag 3 is inflated and expanded to push the massage assembly out; when the pneumatic unit 6 sucks the air in the telescopic air bag 3, the telescopic air bag 3 is deflated and contracted to allow the massage assembly to be retracted. It can be understood that the telescopic air bag 3 can also be in communication with the atmosphere to achieve deflation.

[0090] In some embodiments, please refer to Figure 7 , the pneumatic unit 6 includes a gas source device 61, the gas source device 61 is in fluid communication with the telescopic air bag 3. Exemplarily, the gas source device 61 includes but is not limited to a gas pump, an air compressor or the like, and is provided with a negative pressure air inlet 611 and a positive pressure air outlet 612, the negative pressure air inlet 611 is used for air inflow, and the positive pressure air outlet 612 is used for compressed air outflow. The negative pressure air inlet 611 of the gas source device 61 can be in fluid communication with the external environment, for example, directly with the atmosphere, and the positive pressure air outlet 612 of the gas source device 61 is in fluid communication with the telescopic air bag 3. When the gas source device 61 works, the gas is sucked in from the negative pressure air inlet 611, and the compressed gas is discharged from the positive pressure air outlet 612 to supply air to the telescopic air bag 3.

[0091] In some embodiments, please refer to Figure 7 , the pneumatic unit 6 further includes a fluid distribution device 62, and the gas source device 61 is in fluid communication with the telescopic air bag 3 through the fluid distribution device 62. The fluid distribution device 62 is used to control the opening and closing of the deflation air path of the telescopic air bag 3, and to control the opening and closing of the inflation air path between the telescopic air bag 3 and the gas source device 61.

[0092] In some embodiments, referring to Figure 7 , the fluid distribution device 62 is provided with a distribution inlet 621, a distribution outlet 622 and a distribution exhaust 623, and has an inflation state of making the distribution inlet 621 and the distribution outlet 622 conductive while the distribution exhaust 623 is closed, an exhaust state of making the distribution inlet 621 closed while the distribution outlet 622 and the distribution exhaust 623 are conductive, and a holding state of making the distribution inlet 621 and the distribution exhaust 623 closed. The positive pressure outlet 612 of the gas source device 61 is in fluid communication with the distribution inlet 621 of the fluid distribution device 62, and the distribution outlet 622 is in fluid communication with the flexible air bag 3. For example, the distribution inlet 621 and the positive pressure outlet 612 are in fluid communication through a pipeline, the distribution outlet 622 and the flexible air bag 3 are in fluid communication through a pipeline, and the distribution exhaust 623 is in fluid communication with the atmosphere. When the distribution inlet 621 and the distribution outlet 622 are conductive while the distribution exhaust 623 is closed, the flexible air bag 3 is in fluid communication with the gas source device 61, and the compressed gas in the gas source device 61 is introduced into the flexible air bag 3, i.e. the fluid distribution device 62 is in the inflation state. When the distribution inlet 621 is closed while the distribution outlet 622 and the distribution exhaust 623 are conductive, the flexible air bag 3 is in fluid communication with the atmosphere, and the high-pressure gas in the flexible air bag 3 is discharged into the atmosphere, i.e. the fluid distribution device 62 is in the exhaust state. When the distribution inlet 621 and the distribution exhaust 623 are closed, the flexible air bag 3 is sealed from the gas source device 61 and the atmosphere, i.e. the fluid distribution device 62 is in the holding state. The fluid distribution device 62 can be selected but 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.

[0093] In other embodiments, the distribution exhaust 623 of the fluid distribution device 62 is in fluid communication with the negative pressure inlet 611 of the gas source device 61. For example, the distribution exhaust 623 and the negative pressure inlet 611 are in fluid communication through a pipeline, i.e. the gas in the flexible air bag 3 is sucked through the gas source device 61 to achieve deflation. Deflating the flexible air bag 3 by sucking the gas in the flexible air bag 3 increases the deflation degree of the flexible air bag 3, so that the flexible air bag 3 can be deflated completely and quickly, the massage assembly can be quickly stored in place, the massage member 4 can be quickly withdrawn from the extended position to the retracted position, and the next massage stroke can be ensured, so that the massage starting response speed is faster and the massage experience is enhanced.

[0094] In some embodiments, the number of fluid distribution devices 62 is multiple, the number of stretchable air bags 3 is multiple, the multiple fluid distribution devices 62 are respectively used to control the opening and closing of the deflation air paths of the multiple stretchable air bags 3, and the multiple fluid distribution devices 62 are respectively used to control the opening and closing of the inflation air paths between the multiple stretchable air bags 3 and the air source device 61. The multiple fluid distribution devices 62 and the multiple stretchable air bags 3 can share the same air source device 61, so that a single pneumatic unit 6 can control the inflation and deflation of the multiple stretchable air bags 3.

[0095] In some embodiments, the distribution air inlets 621 of the multiple fluid distribution devices 62 are in fluid communication with the positive pressure air outlets 612 of the same air source device 61. That is, the multiple fluid distribution devices 62 share a single air source device 61, which is conducive to reducing the production cost of the massage equipment 100.

[0096] In some embodiments, referring to Figure 7 , the pneumatic unit 6 further includes a gas storage tank 63, which is in fluid communication between the positive pressure air outlet 612 of the air source device 61 and the distribution air inlet 621 of the fluid distribution device 62. The gas storage tank 63 can be a metal tank, a plastic tank, etc., and can contain high-pressure gas. The gas storage tank 63 can store high-pressure gas, which is conducive to improving the inflation expansion stroke and inflation response speed of the stretchable air bag 3.

[0097] In some embodiments, the pneumatic unit 6 includes a low-pressure generator 64 connected between the distribution air outlet 623 of the fluid distribution device 62 and the negative pressure air inlet 611 of the air source device 61, through which the negative pressure deflation of the stretchable air bag 3 can be realized, and the deflation effect of the stretchable air bag 3 is enhanced.

[0098] For the above-mentioned low-pressure generator 64, referring to Figure 8 , the low-pressure generator 64 is provided with a low-pressure port 6411, a first opening 6412 and a second opening 6413, the low-pressure port 6411 is in fluid communication between the first opening 6412 and the second opening 6413, and the low-pressure port 6411 is used to generate negative pressure when the gas flows from the first opening 6412 to the second opening 6413. That is, the air pressure at the low-pressure port 6411 is lower than the atmospheric pressure. Negative pressure refers to its true air pressure being lower than the standard atmospheric pressure, i.e. lower than 101.325 kilopascals, and negative pressure is usually expressed as its true air pressure minus the standard atmospheric pressure, for example, negative pressure can be -40 kilopascals, -20 kilopascals, -10 kilopascals, etc. When the fluid distribution device 62 controls the deflation of the stretchable air bag 3, the low-pressure port 6411 is brought into fluid communication with the stretchable air bag 3 to realize the deflation of the stretchable air bag 3. By bringing the low-pressure port 6411 into fluid communication with the stretchable air bag 3, the deflation speed of the stretchable air bag 3 is improved, the deflation degree of the stretchable air bag 3 is increased, and the stretchable air bag 3 is deflated more completely and in a shorter time.

[0099] Exemplarily, the low pressure generator 64 comprises a generator body 641, which can be in a tubular shape, and the first opening 6412 and the second opening 6413 are respectively formed at two ends of the generator body 641, and the low pressure port 6411 is formed through the wall of the generator body 641. Thus, the gas flowing from the first opening 6412 to the second opening 6413 flows through the low pressure port 6411, and the flow rate of the gas flowing from the first opening 6412 to the second opening 6413 is greater than the flow rate of the gas in the low pressure port 6411, and the faster the fluid flow rate, the lower the pressure. Therefore, the gas pressure of the gas flowing from the first opening 6412 to the second opening 6413 is lower than the gas pressure in the low pressure port 6411, so that the gas pressure at the low pressure port 6411 is reduced and lower than the atmospheric pressure, that is, a negative pressure is generated.

[0100] In some embodiments, referring to Figure 8 , the low pressure port 6411 is in fluid communication with the distribution exhaust port 623 of the fluid distribution device 62, the first opening 6412 is in fluid communication with the atmosphere, and the second opening 6413 is in fluid communication with the negative pressure intake port 611 of the gas source device 61. Exemplarily, the distribution exhaust port 623 and the low pressure port 6411 are in fluid communication through a pipeline; when the fluid distribution device 62 is in an exhaust state, the distribution air inlet port 622 is in fluid communication with the distribution exhaust port 623, and the gas source device 61 is in a suction intake state, so that the low pressure port 6411 generates a low pressure, thereby the negative pressure deflation of the telescopic air bag 3 is performed through the low pressure generator 64, and the deflation speed of the telescopic air bag 3 is improved.

[0101] In some embodiments, the distribution exhaust ports 623 of the plurality of fluid distribution devices 62 are in fluid communication with the low pressure port 6411 of the same low pressure generator 64. That is, the plurality of fluid distribution devices 62 share a single low pressure generator 64, which is beneficial to reduce the production cost of the massage equipment 100.

[0102] In some embodiments, referring to Figure 8 , the generator body 641 is provided with a low pressure generation chamber 6414, which is arranged in communication between the first opening 6412 and the second opening 6413, and the low pressure generation chamber 6414 comprises a first contraction chamber 64141, one end of the first contraction chamber 64141 away from the first opening 6412 is in fluid communication with the low pressure port 6411. The first contraction chamber 64141 is a chamber with a cross-sectional area gradually decreasing along the direction of fluid flow, which can be in a frustoconical shape. When the gas flows from the first opening 6412 to the second opening 6413 and passes through the first contraction chamber 64141, the cross-sectional area of the chamber allowing the gas to pass through gradually decreases, the flow rate of the gas increases, and the gas pressure decreases when the gas passes through the first contraction chamber 64141, thereby enhancing the negative pressure at the low pressure port 6411. It can be understood that the faster the flow rate of the gas passing through the first contraction chamber 64141, the greater the negative pressure formed at the low pressure port 6411.

[0103] In some embodiments, referring to Figure 8 As shown, the low-pressure generating chamber 6414 further comprises a diffusion chamber 64142 fluidly connected to the first constricted chamber 64141 at an end thereof away from the first opening 6412, the diffusion chamber 64142 having a cross-sectional area greater than that of the first constricted chamber 64141. Exemplarily, the diffusion chamber 64142 is cylindrical, the end of the first constricted chamber 64141 away from the first opening 6412 is fluidly connected to the diffusion chamber 64142, and the diffusion chamber 64142 has an inner diameter greater than that of the port of the end of the first constricted chamber 64141 fluidly connected to the diffusion chamber 64142. When the gas flows from the first constricted chamber 64141 to the diffusion chamber 64142, the cross-sectional area of the chamber through which the gas passes suddenly increases, so the gas is difficult to expand into the entire diffusion chamber 64142; and the flow rate of the gas is large, the gas is ejected in the form of a jet to the second opening 6413, and in the process, the gas in the diffusion chamber 64142 is ejected to the second opening 6413, so as to reduce the gas pressure in the diffusion chamber 64142. And in the embodiment of the utility model, the low-pressure port 6411 is fluidly connected to the first constricted chamber 64141 through the diffusion chamber 64142, which can enhance the negative pressure at the low-pressure port 6411 compared to the low-pressure port 6411 being directly connected to the inner wall of the end of the first constricted chamber 64141 away from the first opening 6412.

[0104] In further embodiments, referring to Figure 8 As shown, the generator body 641 further comprises a constricted cylinder portion 6415 and a nozzle 6416. The constricted cylinder portion 6415 is conical, the end of the constricted cylinder portion 6415 having a larger opening is fluidly connected to the first opening 6412, the other end of the constricted cylinder portion 6415 is directed towards the second opening 6413, and the internal space of the constricted cylinder portion 6415 defines the first constricted chamber 64141. The nozzle 6416 is cylindrical, one end of the nozzle 6416 is fluidly connected to the end of the constricted cylinder portion 6415 having a smaller opening, and the other end of the nozzle 6416 is directed towards the second opening 6413, so that the gas is guided and constrained by the nozzle 6416 after flowing out of the constricted cylinder portion 6415, forming a jet gas flow. The diffusion chamber 64142 is defined between the outer wall of the constricted cylinder portion 6415 and the nozzle 6416 and the inner wall of the generator body 641, so that the rapid gas flow ejected by the nozzle 6416 can more easily cause a negative pressure effect in the diffusion chamber 64142, further enhancing the negative pressure at the low-pressure port 6411.

[0105] In some embodiments, referring to Figure 8As shown, the low pressure generating chamber 6414 further comprises a second converging chamber 64143 fluidly connected to one end of the diffusion chamber 64142 away from the first opening 6412, and a diverging chamber 64144 fluidly connected to one end of the second converging chamber 64143 away from the first opening 6412. The second converging chamber 64143 is a chamber with a cross-sectional area gradually reduced along the direction of fluid flow, which can be in the shape of a frustum of a cone. The diverging chamber 64144 is a chamber with a cross-sectional area gradually increased along the direction of fluid flow, which can be in the shape of a frustum of a cone. It can be understood that the second converging chamber 64143 and the diverging chamber 64144 form a Laval nozzle, which accelerates the gas flowing out of the diffusion chamber 64142, increases the flow rate of the gas flowing through the low pressure generator 64, and further enhances the negative pressure at the low pressure port 6411.

[0106] In some embodiments, referring to Figure 8 As shown, the negative pressure air inlet 611 is fluidly connected to the second opening 6413, for example, through a pipe. In this way, the low pressure driving of the low pressure generator 64 and the air supply for the stretchable air bag 3 are realized by the single air source device 61, without the need to set an additional air pump, thereby reducing the number of air source devices 61, reducing production cost, and reducing energy consumption. In this embodiment, the first opening 6412 can be fluidly connected to the atmospheric environment.

[0107] When the massage device 100 according to the embodiment of the utility model is working, the air source device 61 is started.

[0108] When the pneumatic unit 6 supplies air for the stretchable air bag 3: the fluid distribution device 62 makes the distribution air inlet 621 and the distribution air inlet 622 conductive and the distribution air outlet 623 closed, at this time the fluid distribution device 62 is in the inflation state, the stretchable air bag 3 is fluidly connected to the positive pressure air outlet 612 of the air source device 61, so that the stretchable air bag 3 is inflated and stretched; when the stretchable air bag 3 is inflated and stretched, the massage assembly is driven to move towards the extended position.

[0109] When the massage assembly performs massage: when the massage assembly moves to the extended position, the distribution air inlet and the distribution air outlet 623 are both closed, at this time the stretchable air bag 3 cannot be inflated or deflated, that is, the stretchable air bag 3 is pressure maintaining, and the massage assembly is maintained in the extended position. At this time, the driving device 2 can drive the massage member 4 to rotate to perform massage.

[0110] When the stretchable air bag 3 is deflated, and the pneumatic unit 6 sucks the gas in the stretchable air bag 3: the fluid distribution device 62 makes the distribution air inlet 621 closed and the distribution air inlet 622 and the distribution air outlet 623 conductive, at this time the fluid distribution device 62 is in the exhaust state, the stretchable air bag 3 is fluidly connected to the negative pressure air inlet 611 of the air source device 61, or fluidly connected to the low pressure port 6411 of the low pressure generator 64, so that the stretchable air bag 3 is deflated and contracted; when the stretchable air bag 3 is deflated and contracted, the massage assembly can be moved and retracted towards the retracted position.

[0111] When the massage assembly is housed: when the massage assembly moves to the retracted position, the distribution air inlet 621 is closed, at which time the flexible air bag 3 cannot be inflated or deflated, i.e. the flexible air bag 3 remains normal, and the massage assembly is maintained in the retracted position.

[0112] The massage equipment 100 in the embodiments of the present application can be applied to massage seats, neck massagers, waist massagers, eye massagers, foot massagers, car seats, and the like.

[0113] Based on the same inventive concept, the embodiments of the present application also provide a seat (not shown), which comprises the massage equipment 100. The seat is provided with the massage equipment 100 described above, so that the seat can provide a massage function and improve the use experience.
