Description

Technical Field

[0001] This application relates to the field of massage device technology, and in particular to a massage mechanism and massage device. Background Technology

[0002] Massage chairs utilize mechanical rolling and squeezing forces to achieve massage, which helps relax user muscles and eliminate fatigue. The massage mechanism is the core component that performs the massage actions.

[0003] In some related technologies, the massage mechanism includes multiple air bags arranged in a circumferential direction. The kneading massage is achieved by the alternating inflation and deflation of multiple air bags. This method requires a large number of air bags and a complex control program to precisely control the timing of inflation and deflation of each air bag, resulting in high costs. Furthermore, the inflation and deflation process of the air bags takes time, resulting in slow kneading massage speed and weak intensity. Utility Model Content

[0052] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0053] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0054] Please see Figures 1 to 6 This application provides a massage mechanism 100, which includes a housing 1, a rotating mechanism 2, a driving device 3, a telescopic component 4, and a massage head 5.

[0055] The housing 1 described above serves to house and protect the rotating mechanism 2, the drive device 3, and the telescopic assembly 4. The housing 1 also houses at least a portion of the massage head 5, allowing the massage head 5 to be concealed within the housing 1 when not in operation, thus protecting the massage head 5. The housing 1 may be box-shaped.

[0056] For the rotating mechanism 2 mentioned above, please refer to Figure 2 and Figure 3 The rotating mechanism 2 includes a first rotating component 21 and a second rotating component 22. Both the first rotating component 21 and the second rotating component 22 are rotatably mounted on the housing 1 around a first axis. The second rotating component 22 is connected to the first rotating component 21 in a transmission manner. The second rotating component 22 is used to rotate synchronously with the first rotating component 21. The second rotating component 22 is also used to move relative to the first rotating component 21 in a direction parallel to the first axis.

[0057] That is, the second rotating member 22 can rotate around the first axis under the drive of the first rotating member 21, and can also move relative to the housing 1 in a direction parallel to the first axis. In this embodiment, the massage head 5 is disposed on the second rotating member 22, thereby realizing the rotation and lifting of the massage head 5. The lifting of the massage head 5 means that the massage head 5 moves relative to the housing 1 in a direction parallel to the first axis, so that the massage head 5 can be stored in the housing 1 or extend out of the housing 1.

[0058] The aforementioned drive device 3 is located on the housing 1 and is connected to the first rotating member 21 via a transmission connection. The drive device 3 drives the first rotating member 21 to rotate relative to the housing 1 around a first axis. By driving the first rotating member 21 to rotate, the drive device 3 drives the second rotating member 22 and the massage head 5 to rotate around the first axis, thereby realizing the rotation of the massage head 5.

[0059] In some embodiments, please refer to Figure 2 and Figure 3 The drive device 3 includes a worm gear 31, a worm 32, and a rotary drive component 33. The worm gear 31 is rotatably mounted on the housing 1 around a first axis, and the worm 32 is rotatably mounted on the housing 1, meshing with the worm gear 31. The rotary drive component 33 is mounted on the housing 1 and is driveably connected to the worm 32. The rotary drive component 33 drives the worm 32 to rotate, thereby driving the worm gear 31 to rotate around the first axis. The worm gear 31 is driveably connected to the first rotating component 21, thereby driving the second rotating component 22 and the massage head 5 to rotate around the first axis. The worm gear 32 drives the worm gear 31 to rotate, which has the effect of a speed reducer, i.e., reducing the rotational speed of the massage head 5 and increasing its torque. This improves both the problem of poor massage effect caused by excessively high rotational speed of the massage head 5 and the problem of the massage head 5 failing to rotate due to resistance exceeding its torque.

[0060] Furthermore, the cooperation of the worm gear 31, worm 32 and rotary drive 33 can shorten the thickness of the drive device 3 along the direction parallel to the first axis, thereby shortening the thickness of the massage mechanism 100 along the direction parallel to the first axis.

[0061] Please refer to Figure 1 and Figure 4 The number of housing 1, rotating mechanism 2, telescopic component 4, massage head 5, worm gear 31 and worm 32 can be multiple. One rotating drive component 33 can drive multiple worm gears 32 to rotate, thereby driving multiple massage heads 5 to rotate.

[0062] In some other embodiments, the drive device 3 may also be a disc motor.

[0063] The telescopic component 4 is located on the housing 1 and is connected to the second rotating member 22 via a transmission connection. The telescopic component 4 drives the second rotating member 22 to move relative to the first rotating member 21 in a direction parallel to the first axis. By driving one end of the second rotating member 22 relative to the first rotating member 21 in a direction parallel to the first axis, the telescopic component 4 moves the second rotating member 22 relative to the housing 1 in a direction parallel to the first axis, thereby achieving the raising and lowering of the massage head 5.

[0064] For massage head 5 mentioned above, please refer to Figure 2 and Figure 3The massage head 5 includes a base 51 and massage protrusions 52, with the massage protrusions 52 located on the side of the base 51 opposite to the rotating mechanism 2. The base 51 can be disc-shaped, with its central axis coinciding with the first axis, making the base 51 more stable when rotating. The massage protrusions 52 can be hemispherical, improving the problem of scratching or abrading the user and enhancing massage safety. There can be multiple massage protrusions 52, i.e., two or more, arranged at intervals around the first axis, thus achieving kneading massage when the massage head 5 rotates. The number of massage protrusions 52 can be two, three, four, or five. The multiple massage protrusions 52 can be arranged circumferentially around the first axis, with equal angular intervals.

[0065] In some embodiments, please refer to Figures 4 to 6 The massage protrusion 52 is a ball, which is rotatably mounted on the base 51. When the massage head 5 rotates, the ball rolls to perform kneading massage, which helps to reduce the friction of the massage head 5 during rotation.

[0066] Regarding the specific construction of the rotating mechanism 2 and the telescopic component 4, this application provides two solutions.

[0067] Option 1:

[0068] Please see Figure 2 and Figure 3 The housing 1 includes a guide rod 11, which is parallel to a first axis. The rotating mechanism 2 includes a sliding structure 23, which is slidably disposed on the guide rod 11. A second rotating member 22 is rotatably disposed on the sliding structure 23 about the first axis. The second rotating member 22 is rotatably disposed on the sliding structure 23, and the sliding structure 23 can slide along the guide rod 11, thereby enabling the second rotating member 22 to move relative to the housing 1 about the first axis and in a direction parallel to the first axis.

[0069] For the sliding structure 23 described above, please refer to Figure 2 and Figure 3 The sliding structure 23 includes a first sliding member 231 and a second sliding member 232. The first sliding member 231 is slidably disposed on the guide rod 11. The limiting disk 221 is rotatably clamped between the first sliding member 231 and the second sliding member 232 around the first axis.

[0070] The first sliding member 231 is provided with a first guide hole 2311, and the guide rod 11 passes through the first guide hole 2311, thereby slidably mounting the first sliding member 231 on the guide rod 11. There can be multiple guide rods 11 and multiple first guide holes 2311, with each guide rod 11 passing through a first guide hole 2311, enhancing the stability of the first sliding member 231 slidingly connected to the housing 1.

[0071] Optionally, the second sliding member 232 is provided with a second guide hole (not shown), and the guide rod 11 passes through the first guide hole 2311 and the second guide hole in sequence, thereby slidably mounting the first sliding member 231 and the second sliding member 232 on the guide rod 11. There can be multiple guide rods 11, and multiple first guide holes 2311 and second guide holes. Each guide rod 11 passes through one first guide hole 2311 and one second guide hole in sequence, enhancing the stability of the sliding connection between the first sliding member 231 and the second sliding member 232 and the housing 1.

[0072] In some embodiments, please refer to Figure 3 The guide rod 11 is set close to the inner wall of the housing 1, that is, the guide rod 11 is a guide rib, and the first guide hole 2311 extends to the edge of the first sliding member 231 to form a guide notch. This helps to increase the bending strength of the guide rod 11, improve the problem that the first sliding member 231 cannot slide normally along the guide rod 11 due to the bending of the guide rod 11, and reduce the friction between the first sliding member 231 and the guide rod 11.

[0073] The first sliding member 231 and the second sliding member 232 can be disc-shaped, shortening the thickness of the sliding structure 23 in the direction parallel to the first axis. The limiting disc 221 can be disc-shaped, shortening the distance between the first sliding member 231 and the second sliding member 232, thereby shortening the thickness of the sliding structure 23 in the direction parallel to the first axis.

[0074] The limiting plate 221 is rotatably clamped between the first slider 231 and the second slider 232 about a first axis. For example, please refer to... Figure 2 and Figure 3 The second rotating component 22 includes a bushing 222, a limiting disc 221 fitted onto the bushing 222, a first sliding component 231 having a first limiting hole 2312, and a second sliding component 232 having a second limiting hole 2321. Both ends of the bushing 222 pass through the first limiting hole 2312 and the second limiting hole 2321, respectively. The bushing 222 is drive-connected to the massage head 5 to mount the massage head 5 onto the second rotating component 22. Optionally, the inner diameters of the first limiting hole 2312 and the second limiting hole 2321 are equal to the outer diameter of the bushing 222, meaning the bushing 222 mates with the shaft holes of the first limiting hole 2312 and the second limiting hole 2321, enhancing the stability of the second rotating component 22's rotation relative to the sliding structure 23.

[0075] In some embodiments, a thrust bearing 24 is provided between the limiting disc 221 and the first sliding member 231 and the second sliding member 232 to reduce the frictional force of the second rotating member 22 rotating relative to the sliding structure 23. In this embodiment, the inner diameter of the first limiting hole 2312 and the second limiting hole 2321 can be larger than the outer diameter of the bushing 222, and the first limiting hole 2312 and the second limiting hole 2321 are only used for the bushing 222 to pass through.

[0076] The first sliding member 231 and the second sliding member 232 can be provided with tension by bolts or screws to clamp the limiting plate 221 between the first sliding member 231 and the second sliding member 232. Alternatively, the first sliding member 231 and the second sliding member 232 can be fixed relative to each other, and the limiting plate 221 can be installed between the first sliding member 231 and the second sliding member 232.

[0077] Alternatively, in some other embodiments, please refer to Figure 2 and Figure 3 The telescopic assembly 4 includes a telescopic drive member 41, a fixing member 42, and an elastic member 43. The telescopic drive member 41 is supported on the side of the first sliding member 231 away from the second sliding member 232. The fixing member 42 is provided on the guide rod 11 and is located on the side of the second sliding member 232 away from the first sliding member 231. The elastic member 43 is supported between the fixing member 42 and the second sliding member 232.

[0078] The fixing member 42 can have the same structure as the first sliding member 231 and the second sliding member 232, but the fixing member 42 is fixed to the guide rod 11. For example, please refer to... Figure 3 The fixing member 42 is provided with a third guide hole 421. The guide rod 11 passes through the third guide hole 421, and the guide rod 11 and the third guide hole 421 are interference-fitted, thereby fixing the fixing member 42 to the guide rod 11. There can be multiple guide rods 11 and multiple third guide holes 421. Each guide rod 11 passes through a third guide hole 421, which enhances the stability of the fixing member 42 connected to the housing 1. The fixing member 42 can be disc-shaped to shorten the thickness of the telescopic assembly 4 in the direction parallel to the first axis.

[0079] The elastic element 43 can be a straight spring. The elastic element 43 and the telescopic drive element 41 are respectively supported on the opposite sides of the first sliding element 231 and the second sliding element 232, so as to drive the first sliding element 231 and the second sliding element 232 to clamp the limiting plate 221.

[0080] In some embodiments, please refer to Figure 2 and Figure 3The telescopic drive component 41 is a telescopic air bag. When the telescopic air bag is inflated, it expands to push the sliding structure 23 to slide along the guide rod 11; when the telescopic air bag is deflated, it contracts to pull the sliding structure 23 to slide along the guide rod 11. The telescopic air bag may include multiple bag bodies arranged parallel to the first axis, increasing the telescopic length of the telescopic air bag in the direction parallel to the first axis.

[0081] In this embodiment, the telescopic air bag can be deflated by the compression of the sliding structure 23 and the telescopic air bag by the elastic element 43; or it can be deflated by connecting the telescopic air bag to the low-pressure generator 6, which is used to provide negative pressure.

[0082] The telescopic airbag can also be deflated by magnetic force. For example, the first sliding member 231 is equipped with a magnetic attractor, such as a magnet; the housing 1 is equipped with a magnetically attracted member, such as a magnet or a ferromagnetic metal. When the telescopic airbag is inflated and connected to the atmosphere, the telescopic airbag first deflates and contracts under its own elasticity, causing the distance between the magnetic attractor and the magnetically attracted member to gradually shorten, and the magnetic attraction between the magnetic attractor and the magnetically attracted member to gradually increase. When the magnetic attraction increases to a certain extent, the magnetic attraction drives the first sliding member 231 to squeeze the telescopic airbag, thereby realizing the deflation of the telescopic airbag.

[0083] In some embodiments, please refer to Figure 2 and Figure 3 One end of the telescopic drive component 41 is connected to the housing 1, and the other end is connected to the sliding structure 23. Therefore, the telescopic drive component 41 does not need to rotate synchronously with the second rotating component 22, which helps to reduce the volume and mass of the rotating part in the massage mechanism 100, reduce the energy consumption for driving the massage head 5, and improve the response speed of the massage head 5. When the telescopic drive component 41 is a telescopic air bag, the telescopic air bag does not need to rotate synchronously with the second rotating component 22, making it easier to connect the telescopic air bag to the air tube.

[0084] In other embodiments, one end of the telescopic drive member 41 is connected to the first rotating member 21, and the other end is connected to the second rotating member 22 or the sliding structure 23. The telescopic drive member 41 rotates synchronously with the second rotating member 22. When the other end of the telescopic drive member 41 is connected to the sliding structure 23, the telescopic drive member 41 is rotatably connected to the sliding structure 23, and the telescopic drive member 41 can rotate relative to the sliding structure 23 about a first axis. When the telescopic drive member 41 is a telescopic air bag, the telescopic air bag is lighter, which helps to reduce the mass of the rotating part in the massage mechanism 100, reduce the energy consumption of driving the massage head 5 to rotate, and improve the response speed of the massage head 5 to rotate. In this embodiment, the telescopic air bag needs to be connected to the air tube through a rotary joint.

[0085] The second rotating member 22 is connected to the first rotating member 21 via a transmission connection. For example, please refer to [reference needed]. Figure 2 and Figure 3The first rotating member 21 is provided with a drive shaft 211, and the second rotating member 22 is provided with a bushing 222. The bushing 222 is fitted onto the drive shaft 211. The drive shaft 211 and the bushing 222 are used to transmit torque about a first axis to each other. The drive shaft 211 is used to move relative to the bushing 222 in a direction parallel to the first axis. For example, the cross-section of the drive shaft 211 is adapted to the cross-section of the space inside the bushing 222, and the cross-section is non-circular, such as an ellipse, a polygon, or a closed shape formed by curves and line segments. Thus, the drive shaft 211 can slide within the bushing 222 in a direction parallel to the first axis, and the drive shaft 211 cannot rotate relative to the bushing 222 about the first axis.

[0086] The positions of the drive shaft 211 and the bushing 222 can be interchanged; that is, the first rotating member 21 is equipped with the bushing 222, and the second rotating member 22 is equipped with the drive shaft 211. When the second rotating member 22 is equipped with the drive shaft 211, the limiting plate 221 is sleeved on the drive shaft 211, and the two ends of the drive shaft 211 pass through the first limiting hole 2312 and the second limiting hole 2321 respectively. The drive shaft 211 is connected to the massage head 5 for transmission, so that the massage head 5 is placed on the second rotating member 22.

[0087] In some embodiments, please refer to Figure 2 and Figure 3 The telescopic drive member 41 is annular, and the bushing 222 and / or the drive shaft 211 are at least partially located within the telescopic drive member 41. The telescopic drive member 41 can be an annular telescopic air bag. By surrounding the bushing 222 and / or the drive shaft 211, the telescopic drive member 41 is more compact with the first rotating member 21 and the second rotating member 22, which helps to reduce the volume of the massage mechanism 100. Furthermore, the telescopic drive member 41 surrounding the bushing 222 and / or the drive shaft 211 shortens the distance between the resultant force of the telescopic drive member 41 on the sliding structure 23 and the drive shaft 211, improving the problem of the sliding structure 23 tilting relative to the housing 1, reducing the bending moment between the bushing 222 and the drive shaft 211, and reducing the friction between the bushing 222 and the drive shaft 211. When the telescopic drive member 41 is an annular air bag, it is easier to achieve the annular shape of the telescopic drive member 41. It is understood that in this embodiment, the telescopic drive member 41 is located on the side of the sliding structure 23 facing the first rotating member 21.

[0088] In some embodiments, the telescopic drive member 41 may also be U-shaped, that is, the telescopic drive member 41 partially surrounds the bushing 222 and / or the drive shaft 211.

[0089] In some embodiments, the drive shaft 211 passes through the telescopic drive member 41 and is connected to the bushing 222 in a driving connection; or, the bushing 222 passes through the telescopic drive member 41 and is connected to the drive shaft 211 in a driving connection; or, both the drive shaft 211 and the bushing 222 pass through the telescopic drive member 41 and are connected to each other in a driving connection.

[0090] Option 2:

[0091] Please see Figures 4 to 6 The second rotating member 22 is slidably disposed on the first rotating member 21, and the second rotating member 22 is used to slide relative to the first rotating member 21 in a direction parallel to the first axis. That is, the second rotating member 22 is directly slidably disposed on the first rotating member 21, so that the second rotating member 22 can rotate synchronously with the first rotating member 21, and can also move relative to the first rotating member 21 in a direction parallel to the first axis. Exemplarily, the first rotating member 21 includes a first rotating disk 212 and a plurality of first connecting portions 213, the plurality of first connecting portions 213 being circumferentially spaced and connected to the first rotating disk 212; the second rotating member 22 includes a second rotating disk 223 and a plurality of second connecting portions 224, the plurality of second connecting portions 224 being circumferentially spaced and connected to the second rotating disk 223; the second rotating disk 223 is spaced apart from the first rotating disk 212, and the second connecting portions 224 are slidably connected to the first connecting portions 213, so as to slide the second rotating member 22 on the first rotating member 21. In this embodiment, the massage head 5 can be directly mounted on the second rotating member 22, or the massage head 5 and the second rotating member 22 can be integrated.

[0092] In some embodiments, please refer to Figure 5 and Figure 6 The gap between any two adjacent first connecting portions 213 is adapted to the second connecting portion 224, which is inserted between two adjacent first connecting portions 213. That is, the first connecting portions 213 and the second connecting portions 224 are sequentially engaged around the first axis to slide the second connecting portion 224 and the first connecting portion 213. The engaging surfaces of the first connecting portions 213 and the second connecting portions 224 may be provided with protrusions and grooves respectively to enhance the engaging effect between the first connecting portions 213 and the second connecting portions 224.

[0093] In some other embodiments, the first connecting part 213 can be a sleeve, the second connecting part 224 can be a shaft, the shaft is parallel to the first axis, and the sleeve is fitted onto the bushing 222 to slide the second connecting part 224 and the first connecting part 213.

[0094] Alternatively, in some other embodiments, the accommodating cavity inside the housing 1 is cylindrical, and the inner diameter of the accommodating cavity is equal to the outer diameter of the second rotating disk 223. Thus, the second rotating disk 223 engages with the shaft hole in the inner wall of the accommodating cavity. The second rotating disk 223 can move relative to the housing 1 in a direction parallel to the first axis, or it can rotate relative to the housing 1 around the first axis. The first connecting portion 213 and the second connecting portion 224 are arranged sequentially around the first axis. When the first rotating member 21 rotates until the first connecting portion 213 abuts against the second connecting portion 224, the first rotating member 21 drives the second rotating member 22 to rotate synchronously through the first connecting portion 213. The gap between any two adjacent first connecting portions 213 can be larger than the size of the second connecting portion 224. The first connecting portion 213 and the second connecting portion 224 engage sequentially around the first axis but can have a large engagement gap, meaning that when the first rotating member 21 drives the second rotating member 22 to rotate, there can be a return stroke.

[0095] Understandably, please refer to Figure 5 The first rotating member 21 and the second rotating member 22 enclose a receiving space, and the telescopic component 4 is at least partially located within the receiving space. By placing at least part of the telescopic component 4 within the receiving space, the telescopic component 4 is more compact with the first rotating member 21 and the second rotating member 22, which helps to reduce the size of the massage mechanism 100. Furthermore, the first connecting portion 213 and the second connecting portion 224 surround the telescopic component 4, shortening the distance between the resultant force of the resistance when the second rotating member 22 slides relative to the first rotating member 21 and the telescopic component 4, improving the problem of the second rotating member 22 tilting relative to the first rotating member 21, and reducing the resistance to the sliding of the second rotating member 22 relative to the first rotating member 21.

[0096] In some embodiments, the telescopic component 4 is a telescopic air bag. When the telescopic air bag is inflated, it expands to push the second rotating member 22 to slide relative to the first rotating member 21; when the telescopic air bag is deflated, it contracts to pull the second rotating member 22 to slide relative to the first rotating member 21. The telescopic air bag may include multiple bag bodies arranged in a direction parallel to the first axis, increasing the telescopic length of the telescopic air bag in the direction parallel to the first axis.

[0097] In this embodiment, the telescopic air bag can be deflated by connecting it to a low-pressure generator 6, which provides negative pressure.

[0098] The telescopic airbag can also be deflated by the compression of the second rotating member 22 and the telescopic airbag by the elastic member 43. For example, the elastic member 43 supports the second rotating member 22 and applies an elastic force toward the telescopic airbag to the second rotating member 22. The elastic member 43 can be a straight spring. Since the second rotating member 22 rotates relative to the housing 1, the elastic member 43 is rotatably connected to the second rotating member 22, and the second rotating member 22 can rotate about a first axis relative to the elastic member 43.

[0099] The telescopic airbag can also be deflated by applying tension to the second rotating member 22 via the tension spring 25 to compress the telescopic airbag. Please refer to [link / reference]. Figure 5 and Figure 6 As shown, one end of the tension spring 25 is connected to the first rotating member 21, and the other end of the tension spring 25 is connected to the second rotating member 22, thereby applying a pulling force toward the telescopic air bag to the second rotating member 22. Since the first rotating member 21 and the second rotating member 22 rotate relative to the housing 1, the tension spring 25 rotates synchronously with the first rotating member 21 and the second rotating member 22.

[0100] The telescopic airbag can also be deflated by magnetic force. For example, the second rotating part 22 is equipped with a magnetic attractor, such as a magnet; the housing 1 or the first rotating part 21 is equipped with a magnetically attracted part, such as a magnet or a ferromagnetic metal. When the telescopic airbag is inflated and connected to the atmosphere, the telescopic airbag first deflates and contracts under its own elasticity, which gradually shortens the distance between the magnetic attractor and the magnetically attracted part, and the magnetic attraction between the magnetic attractor and the magnetically attracted part gradually increases. When the magnetic attraction increases to a certain extent, the magnetic attraction drives the second rotating part 22 to squeeze the telescopic airbag, thereby realizing the deflation of the telescopic airbag.

[0101] In some embodiments, please refer to Figure 5 and Figure 6 One end of the telescopic component 4 is connected to the first rotating member 21, and the other end is connected to the second rotating member 22. The telescopic component 4 rotates synchronously with the second rotating member 22. When the telescopic component 4 is a telescopic air bag, the air bag is lightweight, which helps to reduce the mass of the rotating part in the massage mechanism 100, reduce the energy consumption of driving the massage head 5 to rotate, and improve the response speed of the massage head 5 to rotate. In this embodiment, the telescopic air bag needs to be connected to the air pipe through a rotary joint.

[0102] In some other embodiments, one end of the telescopic component 4 is connected to the housing 1, and the other end of the telescopic component 4 is rotatably connected to the second rotating member 22, which is used to rotate relative to the telescopic component 4 about a first axis. Therefore, the telescopic component 4 does not need to rotate synchronously with the second rotating member 22, which helps to reduce the volume and mass of the rotating part in the massage mechanism 100, reduce the energy consumption for driving the massage head 5 to rotate, and improve the response speed of the massage head 5. When the telescopic component 4 is a telescopic air bag, the telescopic air bag does not need to rotate synchronously with the second rotating member 22, facilitating the connection of the telescopic air bag to the air tube.

[0103] For the low-voltage generator mentioned above, please refer to Figure 7 The low-pressure generator 6 includes a generator body 61 and a low-pressure port 62. The generator body 61 has a first opening 611 and a second opening 612. The low-pressure port 62 is fluidly connected between the first opening 611 and the second opening 612. When gas flows from the first opening 611 to the second opening 612, the low-pressure port 62 generates negative pressure, meaning the air pressure at the low-pressure port 62 is lower than atmospheric pressure. Negative pressure refers to a true air pressure lower than standard atmospheric pressure, i.e., lower than 101.325 kPa. Negative pressure is usually expressed as the true air pressure minus standard atmospheric pressure; for example, negative pressure can be -40 kPa, -20 kPa, -10 kPa, etc. By connecting the low-pressure port 62 to a telescopic air bag, the deflating effect of the telescopic air bag is enhanced. Specifically, without the low-pressure generator 6 for auxiliary degassing, the telescopic air bag will directly degas to the external atmosphere. This method results in a slow degassing rate and incomplete degassing, leaving some gas residue inside the air bag. Consequently, the massage head 5 of the massage mechanism 100 cannot fully reset without the addition of a reset device or mechanism. Using the low-pressure generator 6 accelerates the degassing speed of the telescopic air bag and ensures complete degassing, thereby guiding the massage head 5 to achieve a complete reset.

[0104] For example, the generator body 61 can be tubular, with openings at both ends of a first opening 611 and a second opening 612, respectively. A low-pressure port 62 can penetrate the tube wall of the generator body 61. Thus, gas flowing from the first opening 611 to the second opening 612 will flow through the low-pressure port 62. The flow velocity of the gas from the first opening 611 to the second opening 612 is greater than the flow velocity of the gas inside the low-pressure port 62. Since the faster the fluid flow velocity, the lower its pressure, the gas pressure flowing from the first opening 611 to the second opening 612 is less than the gas pressure inside the low-pressure port 62, causing the gas pressure at the low-pressure port 62 to decrease and fall below atmospheric pressure, i.e., generating negative pressure.

[0105] In some embodiments, please refer to Figure 7As shown, the generator body 61 is provided with a low-pressure generating chamber 613, which is connected between the first opening 611 and the second opening 612. The low-pressure generating chamber 613 includes a first contraction chamber 6131, the end of which faces away from the first opening 611 and is in fluid communication with the low-pressure port 62. The first contraction chamber 6131 is a chamber whose cross-sectional area gradually decreases along the direction of fluid flow, and can be shaped like a frustum of a cone. When gas flows from the first opening 611 to the second opening 612, and passes through the first contraction chamber 6131, the cross-sectional area of ​​the chamber through which gas can pass gradually decreases, and the gas velocity increases, causing the gas pressure to decrease when passing through the first contraction chamber 6131, thereby enhancing the negative pressure at the low-pressure port 62. It can be understood that the faster the gas velocity when passing through the first contraction chamber 6131, the greater the negative pressure formed at the low-pressure port 62.

[0106] In some embodiments, please refer to Figure 7 As shown, the low-pressure generating chamber 613 also includes a diffusion chamber 6132, which is in fluid communication with the end of the first contraction chamber 6131 opposite to the first opening 611. The cross-sectional area of ​​the diffusion chamber 6132 is larger than that of the first contraction chamber 6131. ​​For example, the diffusion chamber 6132 is cylindrical, and the end of the first contraction chamber 6131 opposite to the first opening 611 is in fluid communication with the diffusion chamber 6132. The inner diameter of the diffusion chamber 6132 is larger than the inner diameter of the port at the end of the first contraction chamber 6131 in fluid communication with the diffusion chamber 6132. When gas flows from the first contraction chamber 6131 to the diffusion chamber 6132, the cross-sectional area of ​​the chamber through which gas can pass suddenly increases, making it difficult for the gas to expand into the entire diffusion chamber 6132. Furthermore, the gas velocity is relatively high, and the gas is jetted into the second opening 612, carrying gas from the diffusion chamber 6132 into the second opening 612, thus reducing the gas pressure within the diffusion chamber 6132. Furthermore, in this embodiment of the invention, the low-pressure port 62 is in fluid communication with the first contraction chamber 6131 through the diffusion chamber 6132. Compared with the low-pressure port 62 being directly connected to the inner wall of the first contraction chamber 6131 away from the first opening 611, this can enhance the negative pressure at the low-pressure port 62.

[0107] In further embodiments, please refer to Figure 7As shown, the generator body 61 also includes a converging cylinder 614 and a nozzle 615. The converging cylinder 614 is conical in shape, with its larger opening end in fluid communication with a first opening 611, and its other end facing a second opening 612. The internal space of the converging cylinder 614 defines a first converging chamber 6131. ​​The nozzle 615 is cylindrical, with one end in fluid communication with the smaller opening end of the converging cylinder 614, and its other end facing the second opening 612. This allows the gas flowing out of the converging cylinder 614 to be guided and constrained by the nozzle 615, forming a jet stream. A diffuser chamber 6132 is defined between the outer wall of the converging cylinder 614 and the nozzle 615, and the inner wall of the generator body 61. This allows the rapid airflow ejected from the nozzle 615 to more easily induce a negative pressure effect in the diffuser chamber 6132, further enhancing the negative pressure at the low-pressure port 62.

[0108] In some embodiments, please refer to Figure 7 As shown, the low-pressure generating chamber 613 also includes a second contraction chamber 6133 and an expansion chamber 6134. The second contraction chamber 6133 is fluidly connected to the end of the diffusion chamber 6132 opposite to the first opening 611, and the expansion chamber 6134 is fluidly connected to the end of the second contraction chamber 6133 opposite to the first opening 611. The second contraction chamber 6133 is a chamber whose cross-sectional area gradually decreases along the direction of fluid flow and can be shaped like a frustum of a cone. The expansion chamber 6134 is a chamber whose cross-sectional area gradually increases along the direction of fluid flow and can also be shaped like a frustum of a cone. It can be understood that the second contraction chamber 6133 and the expansion chamber 6134 form a Laval tube, which accelerates the gas flowing out of the diffusion chamber 6132, increases the flow velocity of the gas through the low-pressure generator 6, and further enhances the negative pressure at the low-pressure port 62.

[0109] In some embodiments, please refer to Figure 7 As shown, the low-pressure generator 6 also includes a silencer 63, which is disposed in the first opening 611. The silencer 63 can be a sound-absorbing sheet, sound-absorbing cotton, etc. By disposing of the silencer 63 in the first opening 611, the noise generated when the low-pressure generator 6 draws air into the external environment through the first opening 611 can be reduced, thus reducing adverse effects on surrounding personnel. Optionally, the silencer 63 is embedded in the inner wall of the first opening 611 and covers the first opening 611. It is understood that the silencer 63 is gas permeable.

[0110] To ensure that the massage head 5 can be fully reset without adding an additional reset device, please refer to [link / reference needed]. Figure 8This application provides a massage device (not shown), which includes the aforementioned massage mechanism 100 and a pneumatic system 200. The pneumatic system 200 includes an air source device 7, a fluid distribution device 8, and the aforementioned low-pressure generator 6. The fluid distribution device 8 is used to control the opening and closing of the air leakage path between the telescopic air bag of the massage mechanism 100 and the low-pressure generator 6, and to control the opening and closing of the air inflation path between the telescopic air bag of the massage mechanism 100 and the air source device 7. The telescopic air bag is fluidly connected through the low-pressure port 62. Because the low-pressure port 62 generates negative pressure, it increases the air leakage speed of the telescopic air bag, increases the degree of air leakage, and makes the air leakage of the telescopic air bag more complete and complete in a shorter time. It should be noted that... Figure 8 The telescopic drive component 41 is a telescopic air bag.

[0111] For the gas source device 7 mentioned above, please refer to Figure 8 As shown, the gas source device 7 is equipped with an intake port 71 and an exhaust port 72. The intake port 71 is for gas to flow in, and the exhaust port 72 is for gas to flow out. When the gas source device 7 is working, it draws in gas through the intake port 71 and then discharges compressed gas through the exhaust port 72 to supply gas. The intake port 71 of the gas source device 7 can be fluidly connected to the external environment, such as directly connected to the atmosphere. The exhaust port 72 of the gas source device 7 can be fluidly connected to the telescopic air bag through the fluid distribution device 8 to supply gas to the telescopic air bag.

[0112] Please refer to Figure 8 As shown, the air intake 71 is in fluid communication with the second opening 612, for example, through a pipe. Thus, a single air source device 7 can be used to drive the low-pressure generator 6 at low pressure and supply air to the telescopic air bag, eliminating the need for an additional air pump, reducing the number of air source devices 7, lowering production costs, and reducing energy consumption.

[0113] The fluid distribution device 8 includes a valve assembly 81. The valve assembly 81 connects the exhaust port 72 to the telescopic air bag in fluid communication and controls the opening and closing of the air passage between the exhaust port 72 and the telescopic air bag. The valve assembly 81 also connects the low-pressure port 62 to the telescopic air bag in fluid communication and controls the opening and closing of the air passage between the low-pressure port 62 and the telescopic air bag. For example, the valve assembly 81 has an air inlet 811, an inflation port 812, and a deflation port 813. The air inlet 811 is in fluid communication with the exhaust port 72 via a pipe, the inflation port 812 is in fluid communication with the telescopic air bag via a pipe, and the deflation port 813 is in fluid communication with the low-pressure port 62 via a pipe. The valve assembly 81 controls the opening and closing of the air passage between the inflation port 812 and the air inlet 811 and the deflation port 813, thereby controlling the opening and closing of the air passage between the telescopic air bag and the air source device 7 and the low-pressure generator 6. The valve assembly 81 can be selected, but is not limited to, air valves, such as solenoid valves or SMA (Shape Memory Alloy) valves.

[0114] In some embodiments, please refer to Figure 8 As shown, the pneumatic system 200 also includes an air tank 9, which is fluidly connected between the air source device 7 and the fluid distribution device 8. The air tank 9 can be a metal tank, a plastic tank, etc., and can contain high-pressure gas. The storage of high-pressure gas in the air tank 9 is beneficial for improving the inflation speed and inflation response speed of the telescopic air bag.

[0115] Based on the same inventive concept, this application also provides a massage device (not shown), which includes a massage mechanism 100. The massage device possesses the structural features and beneficial effects of the massage mechanism 100, which will not be elaborated here. Massage devices include, but are not limited to, massage chairs, neck massagers, waist massagers, eye massagers, foot massagers, and car seats.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
