Description

Technical Field

[0001] This invention relates to the field of massage instrument technology, and in particular to a massage mechanism and massager with adjustable massage interval. Background Technology

[0002] A shoulder and neck massage shawl is a device specifically designed for massaging and caring for the shoulder and neck areas. The massage mechanism is the main component of the shawl, typically including a motor, transmission components, a drive shaft, shoulder massage components, and neck massage components. The motor drives the drive shaft to rotate via the transmission components, causing the shoulder and neck massage components to reciprocate, thus massaging the shoulders and neck.

[0003] In the prior art, there are at least two types of massage shawls for the shoulders and neck: one is a massage shawl with a driven shaft structure, as shown in patent publication number CN219398106U; the other is a massage shawl without a driven shaft, as shown in patent publication number CN221636603U. To accommodate users of different body types, existing technologies include massage mechanisms with adjustable massage head spacing, as shown in patent publication numbers CN221770762U and CN121818333A. Patent publication number CN221770762U discloses an adjustable-width massager, including two massage components, a rotating shaft, a housing, and an adjustment assembly. Each massage component includes a massage element, a first threaded element, and a second threaded element. The first threaded element is rotatably connected to the massage element. The second threaded element includes a threaded portion and a connecting portion, with the threaded portion screwed into the first threaded element. The rotating shaft passes through the two massage components. The housing has a first accommodating groove and two first accommodating cavities connected in a line. A connecting portion is disposed within one of the first accommodating cavities. The adjustment assembly includes a transmission sleeve and a torsion element disposed within the first accommodating groove. The torsion element is rotatable around a central axis and connected to the housing. The inner surface of the transmission sleeve abuts against the circumferential surfaces of the torsion element and the connecting portion. The transmission sleeve is disposed within the first accommodating groove and the first accommodating cavity. This patent document relies on a threaded structure on the outer wall of the drive shaft to move the massage components along the axial direction of the drive shaft, thereby adjusting the distance between the two massage components. This method is not suitable for massage shawls without a drive shaft.

[0004] Regarding the adjustment of the massage spacing in a shoulder and neck massage shawl without a drive shaft, patent publication number CN121818333A discloses a massage mechanism with adjustable massage head spacing, including a housing; several swing seats, each rotatably disposed within the housing; several transmission shafts, rotatably disposed on corresponding swing seats; a drive device installed within the housing, with its drive end connected to the transmission shafts to drive the massage heads to rotate; and an adjustment device installed within the housing, with its drive end connected to the swing seats for driving the swing seats to swing; the drive device includes at least a rotary drive component installed within the housing, with its drive end connected to the transmission shafts; the spacing between the transmission shafts is adjusted by driving the swing seats to swing through the adjustment device, thereby changing the spacing between the massage heads mounted on the transmission shafts.

[0005] In this patent document, the swing seat is rotated around the pivot by an adjustment device (i.e., an arc-shaped adjustment method is used). However, when the width of the two massage components changes, there is also an unnecessary displacement change in the vertical direction along the width adjustment direction of the massage components, which affects the massage comfort. Moreover, the comfort changes every time the massage spacing is adjusted, which affects the precise control of the massage technique. Summary of the Invention

[0014] Secondly, the present invention provides a massager, including a massage mechanism with adjustable massage spacing as described in the first aspect. The massager also includes a shawl upper shell, a shawl lower shell, and a battery for power supply. The bottom of the mechanism shell has a mounting position, and the battery is disposed in the mounting position. The shawl upper shell and the shawl lower shell enclose a receiving space, and the massage mechanism is disposed in the receiving space. The shawl upper shell has a hole that exposes the massage end of the massage component.

[0015] The beneficial effects of this invention are as follows: 1. By adjusting the connecting rod, the massage components on both sides move synchronously in opposite directions in a straight line, avoiding the unnecessary vertical displacement caused by the arc adjustment of the massage components in the prior art. Moreover, during the adjustment of the distance between the massage components, the second transmission gear can adaptively adjust its meshing position with the gear seat and the first transmission gear as the massage components move, so that the second transmission gear always remains in mesh with the transmission unit and the gear seat.

[0016] 2. This invention can be used with a first motor to automatically match the width of the human neck and shoulders. During the process of adjusting the spacing of the massage components to adapt to the neck width of different users, when the massage arm comes into contact with the human neck, the motor load increases sharply due to the resistance of the human body. The motor operating current will show a rapid upward trend. The control board detects the change in the operating current of the first motor and immediately controls the motor to stop rotating, thereby automatically adapting to the neck thickness of users of different body types.

[0017] 3. In addition, besides automatically adjusting the massage width to match different user body shapes by detecting the working current of the first motor in conjunction with the first Hall detection board, the control board can also detect the working current of the massage drive motor. This allows the actual massage load (i.e., the massage intensity) to be determined by monitoring the changes in the working current of the massage drive motor when the massage components are performing massage. This enables the first motor to fine-tune the distance between the two massage components, thereby adjusting the massage intensity and greatly increasing the massage comfort experience, thus achieving intelligent massage.

[0018] 4. The spacing of the massage components is adjusted by using a combination of screw and nut and worm gear. With the force amplification characteristics of the screw and worm gear, the power is amplified. Therefore, only a small torque is needed to complete the adjustment action, so the first motor can be used as the power source, effectively reducing the internal assembly space of the whole machine and greatly reducing the overall size of the mechanism.

Detailed Implementation

[0048] Example 1, please refer to Figures 1 to 27This invention provides a massage mechanism with adjustable massage spacing, including a mechanism housing 1, a guide 2, a linear motion component 3, an adjustment drive assembly 4, an adjustment linkage 6, a first motor, massage components 5, and a massage drive assembly 12. The massage mechanism has a center surface 7 at its center, and two sets of massage components 5 are symmetrically arranged on both sides of the center surface 7. The massage drive assembly 12 includes: a massage drive motor 121, a transmission unit, a second transmission gear 124, a gear seat 125, a lower gear seat linkage 126, an upper gear seat linkage 127, and a transition linkage 128. The output end of the massage drive motor 121 is connected to the transmission unit. The gear seat 125 is connected to the massage component 5 and is used to drive the massage arm to perform massage actions, and the lower gear seat linkage is hinged to the massage component. In this embodiment, the massage arm refers to the neck massage arm 5412 (or the massage head fixing seat 5415) and the shoulder massage arm 5423.

[0049] The output end of the transmission unit is connected to the gear seat 125 via the second transmission gear 124. The upper gear seat connecting rod 127 and the lower gear seat connecting rod 126 are rotatably connected to the upper and lower sides of the gear seat 125, respectively, and the second transmission gear 124 is rotatably connected to the lower gear seat connecting rod 126. The upper gear seat connecting rod 127 has a nested portion 1272, which is coaxial with the second transmission gear 124. One end of the transition connecting rod 128 and the adjusting connecting rod 6 are both hinged to the nested portion 1272. The other end of 28 is rotatably connected to the output end of the transmission unit, and the other end of the adjusting rod 6 is hinged to the linear motion component 3; the guide 2 is located between the core housing 1 and the massage component 5; the moving direction of the linear motion component 3 is perpendicular to the sliding direction of the guide; the first motor is connected to the adjusting drive assembly 4, and drives the linear motion component 3 to move through the adjusting drive assembly 4, so that the adjusting rod 6 swings, thereby the two sets of massage components 5 move synchronously towards or away from each other, that is, the two sets of massage components 5 move symmetrically about the central plane 7.

[0050] The massage mechanism also includes a first induction magnet, a control board 23, and two first Hall effect detection boards 10. The first motor and the massage drive motor are respectively connected to the control board 23 and controlled by the control board 23. The control board 23 is provided with a current module and a current detection module. The current module is connected to the first motor and is used to detect the operating current of the first motor. The current detection module is connected to the massage drive motor and is used to detect the operating current of the massage drive motor. A first induction magnet is installed on any one of the components, including the adjusting linkage, transition linkage, upper gear seat linkage, lower gear seat linkage, second transmission gear, and gear seat. The mechanism housing is provided with a wide position detection mounting position 105 and a narrow position detection mounting position 106. The wide position detection mounting position 105 and the narrow position detection mounting position 106 correspond to the two extreme positions of the movement of the component where the first induction magnet is located. Two first Hall effect detection plates 10 are respectively installed in the wide position detection mounting position 105 and the narrow position detection mounting position 106. The two first Hall effect detection plates 10 are respectively used to detect the widest and narrowest positions of the distance between the two massage components 5. As shown in the figure, in this embodiment, the first sensing magnet is preferably installed at the end of the two adjusting rods 6 connected to the adjusting nut 302. The top of the upper shell 101 of the movement is provided with a wide position detection mounting position 105 and a narrow position detection mounting position 106. The two first Hall detection plates 10 are installed in the wide position detection mounting position 105 and the narrow position detection mounting position 106.

[0051] The massage mechanism also includes a sensing component for detecting the position of the massage arm. The sensing component includes a second sensing magnet and a second Hall effect detection plate 15. The second sensing magnet is connected to a gear seat 125 or a transmission unit. The second Hall effect detection plate 15 is located at a position corresponding to the second sensing magnet. Using a first motor as the power source, it can automatically detect the width of the user's neck and move the left and right massage components 5 simultaneously to fit the corresponding left and right sides of the human neck. This solves the problem to the greatest extent that users of different body types have different neck thicknesses, resulting in excessive massage intensity (e.g., male users with relatively thick necks) or insufficient massage intensity (e.g., female users with relatively thin necks) and massage position deviations. For example, if it is originally set to massage the Fengchi acupoint, it will not be able to reach it because the neck is thick, or it will massage beyond the Fengchi acupoint area and onto the scalp because the neck is thin, causing discomfort.

[0052] The specific implementation steps are as follows: 1. First, the massage drive motor 121 rotates, driving the neck massage arm 5412 (or massage head fixing seat 5415) and shoulder massage arm 5423 of the massage component 5 to be clamped to the narrowest position. The number of rotations of the massage drive motor 121 is determined by the second Hall detection plate 15 in conjunction with the second Hall detection plate 15. By clamping the neck massage arm 5412 (or massage head holder 5415) and the shoulder massage arm 5423 to their narrowest positions, space can be saved and packaging can be made easier during product shipment.

[0053] 2. When the neck massage arm 5412 (or massage head fixing seat 5415) and shoulder massage arm 5423 of the massage component 5 are in the narrowest position, the massage drive motor 121 stops first, and the first motor rotates (the default setting is the direction away from the neck). When the massage component 5 is widened to the widest position (determined by the first Hall detection plate 10 at the width detection mounting position 105), the first motor rotates in the opposite direction to move the left and right massage components 5 toward the neck until they touch the sides of the human neck.

[0054] During the adjustment of the spacing between the massage components, the second transmission gear can adaptively adjust its meshing position with the gear seat and the first transmission gear as the massage components move, ensuring that the second transmission gear is always engaged with the transmission unit and the gear seat. By adjusting the connecting rod to pull the massage components on both sides to move synchronously in opposite directions in a straight line, the unnecessary vertical displacement caused by the arc adjustment of the massage components in the prior art is avoided.

[0055] When the massage component 5 is placed against both sides of the neck, the resistance to movement increases immediately, and the operating current of the first motor increases sharply. When the current module on the control board 23 detects this change in current, the first motor stops immediately or rotates in the opposite direction for the set number of revolutions and then stops. At this time, the massage drive motor 121 starts to run and performs massage according to the set massage program.

[0056] In addition, by detecting the working current of the first motor in conjunction with the first Hall effect sensor 10 at the width detection mounting position 105, the massage width can be automatically adjusted to match different user body shapes. During the massage process, the working current of the massage drive motor 121 can also be detected by the current detection module on the control board 23. This allows the actual massage load (i.e., the massage force) to be determined by monitoring the changes in the working current of the massage drive motor 121 when the massage component 5 is performing massage. This enables the first motor to fine-tune the distance between the two massage components 5, achieving precise adjustment of the massage force and enabling precise control of the massage technique, greatly increasing the massage comfort experience.

[0057] Specifically, the linear motion component 3 includes an adjusting rod 301 and an adjusting nut 302. The adjusting drive assembly 4 is connected to the adjusting rod 301, and the adjusting rod 301 is rotatably connected to the movement housing 1. The adjusting nut 302 is screwed onto the outer wall of the adjusting rod 301. The other end of the adjusting connecting rod 6 is hinged to the adjusting nut 302. More specifically, as shown... Figure 18 As shown, the top of the adjusting nut 302 is integrally formed with a hinge part 303, and the other ends of the two adjusting rods 6 are hinged to the hinge part 303; the threaded drive method requires less torque from the motor that drives the adjusting rod 301 to rotate, so a first motor can be used, which greatly saves space.

[0058] When the first motor is used to adjust the distance between the two massage components 54, a first sensing magnet 8 can be installed on the upper part of the other end of the adjusting rod 6. After the first fixing screw 9 passes through the first sensing magnet 8, it is threadedly connected to the hinge part 303 to constrain the displacement of the first sensing magnet 8 and the adjusting rod 6 along the axial direction of the hinge part 303. The first sensing magnet 8 cooperates with two first Hall effect detection plates 10 to detect the widest and narrowest positions of the distance between the two massage components 54. When the knob 454 is used to manually adjust the distance between the two massage components 54 by the user, the first fixing screw 9 is threadedly connected to the hinge part 303 to constrain the displacement of the two adjusting rods 6 along the axial direction of the hinge part 303.

[0059] The adjustment drive assembly 4 includes a first adjustment gear 41, a second adjustment gear 42, and a third adjustment gear 43, such as Figure 15 As shown, the lower case 102 of the movement has an adjusting gear mounting position 103 on its side. The adjusting gear mounting position 103 is also connected to an adjusting gear cover 24. The adjusting gear mounting position 103 has a first rotating shaft hole 1031, a second rotating shaft hole 1032, and a rotating part 1033. The second adjusting gear 42 is rotatably connected to the outer wall of the rotating part 1033. The inner wall of the movement case 1 also has a third rotating shaft hole 1034 corresponding to the first rotating shaft hole 1031. The adjusting rod 301 passes through the first rotating shaft hole 1031 and connects to the third rotating shaft hole 1034. Figure 16 As shown, the first pivot hole 1031 and the third pivot hole 1034 are used to support the adjusting rod 301; The first adjusting gear 41 is connected to the adjusting rod 301. One end of the adjusting rod 301 has a first head that is hexagonal in shape. The end face of the first adjusting gear 41 is provided with a first groove. The first head is embedded in the first groove so that the adjusting rod 301 and the first adjusting gear 41 are fixedly connected. The second adjusting gear 42 is meshed with the first adjusting gear 41 and the third adjusting gear 43. The third adjusting gear 43 is connected to an adjusting shaft 44, and the adjusting shaft 44 is connected to a driving member 45. One end of the adjusting shaft 44 has a hexagonal second head, and the end face of the third adjusting gear 43 is provided with a second groove, in which the second head is embedded. The bottom of the lower housing 102 of the movement has a driving member mounting position 104, and the driving member mounting position 104 is provided with a fourth rotating shaft hole 1035. The adjusting shaft 44 passes through the second rotating shaft hole 1032 and is connected to the fourth rotating shaft hole 1035.

[0060] In this embodiment, the driving component 45 is an interlaced shaft transmission mechanism. There are two types of interlaced shaft transmission mechanisms: the first uses interlaced gear transmission, and the second uses a worm gear transmission with a self-locking function. Specifically, the first type of interlaced shaft transmission mechanism is as follows: the driving component 45 includes a first interlaced gear 451 and a second interlaced gear 452, located within the driving component mounting position 104. The first interlaced gear 451 is connected to the adjusting shaft 44, and the second interlaced gear 452 meshes with the first interlaced gear 451. The second interlaced gear 452 is connected to a power component. The power component can be a knob 454, allowing manual adjustment by the user. Alternatively, the power component can be driven by a first motor.

[0061] When manually adjusted: the power component includes a knob lever 453 and a knob 454. The knob lever 453 is fixedly connected to the second interlaced gear 452, and the knob 454 is connected to the knob lever 453. The massage mechanism also includes an interlaced gear cover 11, which is used to constrain the first interlaced gear 451, the second interlaced gear 452, and the knob lever 453 within the drive component mounting position 104. The interlaced gear cover 11 has an exposure hole, and one end of the knob lever 453 passes through the exposure hole and connects to the knob 454. By rotating the knob 454, the user can move the two massage components 5 simultaneously to the corresponding left and right sides of the neck to fit the user's neck, adapting to the neck thickness of users with different body types. To avoid deviations in massage intensity or location due to differences in neck thickness among users, such as when the distance between the two massage components 5 remains constant, users with thicker necks may experience greater massage intensity, while those with thinner necks may experience less. Massage locations (such as the pre-set Fengchi acupoint) may be missed due to a thicker neck, or the massage may extend beyond the Fengchi acupoint area to the scalp, causing discomfort. When automatic adjustment is used, the power component is a first motor, which is fixed to the bottom of the lower housing 102 of the mechanism. The output end of the first motor is connected to the second interlocking gear 452. Replacing the knob 454 with the first motor allows it to be placed at any position around the adjustment shaft 44, facilitating spatial layout and saving space.

[0062] The second form of the interlaced shaft transmission mechanism specifically includes a worm gear and a first worm. The worm gear is connected to the adjusting shaft 44, and the first worm meshes with the worm gear. In this form, the width of the two massage components 54 can also be adjusted. During manual adjustment, the knob lever 453 is connected to the first worm, and the knob 454 is connected to the knob lever 453. When using a first motor, the output end of the first motor is connected to the first worm, or the first worm can be integrally formed on the output shaft of the first motor. In the second form of the interlaced shaft transmission mechanism, a helical gear matching the first worm can also replace the worm gear. Compared to the first form of the interlaced shaft transmission mechanism, the worm gear and worm wheel structure gives the drive component 45 a self-locking function to prevent changes in the distance between the two massage components 54 during use.

[0063] Specifically, the mechanism housing 1 includes an upper mechanism housing 101 and a lower mechanism housing 102, with an installation space between the upper mechanism housing 101 and the lower mechanism housing 102, and one end of the massage component 5 is disposed within the installation space; The massage component 5 includes a massage upper cover 51, a massage middle cover 52, a massage lower cover 53, and a massage assembly 54. One end of the massage assembly 54 is installed between the massage middle cover 52 and the massage lower cover 53, and the massage end of the massage assembly 54 extends through the massage upper cover 51 to the outside of the core housing 1. The guide member 2 is a sliding rib provided at the bottom of the massage lower cover 53, and the lower shell 102 of the mechanism is provided with a sliding groove 107, and the sliding rib is slidably connected in the sliding groove 107; The transmission unit includes a massage drive motor 121, a helical gear 122, a first transmission gear 123, a first step pin 13, and a second step pin 14. The output end of the massage drive motor 121 is a second worm gear, which meshes with the helical gear. The lower housing 102 of the mechanism has a connecting shaft 108. The helical gear 122 and the first transmission gear 123 are sleeved on the outer wall of the connecting shaft 108, and the helical gear and the first transmission gear are fixedly connected. The meshing connection between the helical gear 122 and the second worm gear is shown in CN218165584U or CN201139742Y. Of course, the helical gear 122 can also be replaced with a worm wheel.

[0064] The massage mechanism also includes a sensing component for detecting the position of the massage arm. The sensing component includes a second sensing magnet and a second Hall effect detection plate 15. The bottom of the helical gear 122 or the top of the gear seat 125 is provided with a magnet mounting groove 1221, and the second sensing magnet is installed in the magnet mounting groove 1221. When the second sensing magnet is installed at the bottom of the helical gear 122, the second Hall detection plate 15 is located at the position corresponding to the second sensing magnet on the lower shell 102 of the mechanism; when the second sensing magnet is installed at the top of the gear seat 125, the second Hall detection plate 15 is located at the position corresponding to the second sensing magnet on the massage cover 51. Compared to mounting the second sensing magnet at the bottom of the helical gear, mounting the second sensing magnet at the top of the gear seat, along with the second Hall effect sensor plate at the massage cover, allows for more precise control of the narrow position of the massage arm.

[0065] The lower gear seat connecting rod 126 is rotatably connected to the massage middle cover 52. The lower gear seat connecting rod 126 is provided with a first rotating part 1261 and a second rotating part 1262. The gear seat 125 is rotatably connected to the outer wall of the first rotating part 1261. The second transmission gear 124 is rotatably connected to the outer wall of the second rotating part 1262, and the second transmission gear 124 is meshed with the first transmission gear 123 and the gear seat 125. The upper gear seat connecting rod 127 is provided with a connecting hole 1271, the upper end of the gear seat 125 is rotatably connected in the connecting hole 1271, and the nesting part 1272 is rotatably connected to the center of the second transmission gear 124. The second stepped pin 14 passes through the second rotating part 1262 and the adjusting rod 6, extending to the upper end of the adjusting rod 6; after the second stepped pin 14 exits the adjusting rod 6, it is fixed with a retaining ring. The other end of the transition rod 128 is rotatably connected to the first transmission gear 123; the first stepped pin 13 passes through the transition rod 128 and the connecting shaft 108, extending to the bottom of the lower housing 102 of the movement. After the first stepped pin 13 exits the lower housing 102 of the movement, it is fixed with a retaining ring.

[0066] Specifically, the massage assembly 54 includes a neck massage assembly 541 and a shoulder massage assembly 542. The shoulder massage assembly 542 includes: a connecting rod seat 5421, a ball joint connecting rod 5422, a shoulder massage arm 5423, a first pin 5424, and a second pin 5425. The bottom of the gear seat 125 is provided with a mounting hole 1251, which is offset from the center of the gear seat 125. The upper end of the connecting rod seat 5421 has a mounting part 54211, which is rotatably connected to the mounting hole 1251. The upper end of the gear seat 125 is provided with a recessed space 1252, and the bottom wall of the recessed space 1252 is provided with a countersunk hole. The upper end of the mounting part 54211 extends into the countersunk hole. A nut 16 is installed inside the connecting rod seat 5421, and a stepped screw 17 passes through the connecting rod seat 5421 and is connected to the nut 16. The connecting rod seat 5421 is connected to a first pin 5424, the first pin 5424 is connected to a ball joint connecting rod 5422, one end of the shoulder massage arm 5423 is provided with a spherical groove, the end of the ball joint connecting rod 5422 is provided with a ball head, the ball head is spherically hinged in the spherical groove, and the shoulder massage arm 5423 is also connected to a ball head cover 5426 that constrains the ball head of the ball joint connecting rod 5422 in the spherical groove. The massage middle cover 52 is equipped with a second pin 5425, and the second pin is rotatably connected to the shoulder massage arm 5423. When the gear seat 125 rotates, since the mounting part 54211 and the mounting hole 1251 are rotatably connected, the connecting rod seat 5421 revolves around the axis of the gear seat 125, but the connecting rod seat 5421 itself does not rotate. When the connecting rod seat 5421 revolves around the axis of the gear seat 125, the distance between the axis of the first pin 5424 and the center of the ball head changes continuously, causing the end of the ball head connecting rod 5422 away from the ball head to rotate around the first pin 5424. Then, the ball head connecting rod 5422 drives the shoulder massage arm 5423 to rotate around the second pin 5425, causing the massage end of the shoulder massage arm 5423 to move up and down reciprocally. The sidewall of the sunken space 1252 is provided with a plurality of protrusions 1253, and a fitting groove is formed between adjacent protrusions 1253. The lower end of the neck massage component 541 is provided with a fitting part 54111 corresponding to the fitting groove. The fitting part 54111 is connected in the fitting groove, so that the neck massage component 541 is circumferentially fixed to the gear seat 125.

[0067] In this embodiment, the neck massage component 541 has two structures. The first structure of the neck massage component 541 is as follows: the neck massage component 541 includes: an eccentric wheel 5411, a neck massage arm 5412, and a neck massage head 5413; the fitting part 54111 is located at the bottom of the eccentric wheel 5411, and the eccentric wheel 5411 is composed of an integrally formed inner ring 54112 and an outer ring 54113, such as... Figure 14 As shown, the axis of the inner ring is inclined to the axis of the gear seat 125. In this invention, the upper surfaces of both the inner and outer rings are inclined surfaces. The lower end of the neck massage arm is rotatably connected to the center of the inner ring. The lower end of the neck massage arm has a screw hole. The first screw 18 passes through the washer and is screwed into the screw hole. The bottom of the recessed space 1252 is also provided with a relief inclined surface 19 for avoiding the first screw. By setting the stepped screw 17 and the first screw 18 in the recessed space, this invention can further save space and make the massage mechanism smaller.

[0068] The neck massage head 5413 is detachably connected to the upper end of the neck massage arm 5412. The neck massage arm 5412 has guide blocks 5414 on both sides. The upper surface of the guide block 5414 is arc-shaped. The massage cover 51 has a through hole 511. The upper end of the neck massage arm 5412 extends through the through hole 511 to the outside of the massage cover 51. The massage cover 51 also has a guide groove 512 that communicates with the through hole. The guide block 5414 is movably connected in the guide groove 512. When the gear seat 125 rotates, the eccentric wheel 5411 drives the massage end of the neck massage arm 5412 to swing back and forth. At the same time, the guide blocks 5414 on both sides of the same neck massage arm 5412 move up and down alternately within the guide groove 512. The upper surface of the guide block 5414 is arc-shaped, so that the guide block 5414 and the guide groove 512 are in line contact, resulting in low frictional resistance between the guide block and the guide groove.

[0069] The second structure of the neck massage component 541 is as follows: The neck massage component 541 includes a massage head fixing seat 5415 and a massage disc 5416; the fitting part 54111 is provided at the bottom of the massage head fixing seat 5415, the massage head fixing seat 5415 is coaxially connected to the gear seat 125, the top of the massage head fixing seat 5415 has a fixed shaft 5417, the axis of the fixed shaft 5417 is parallel to the axis of the gear seat 125, and the massage disc 5416 is installed at the top of the fixed shaft 5417. Furthermore, in both structures of the neck massage component 541, a flange portion 109 for constraining the eccentric wheel or the massage head fixing seat is integrally formed on the upper shell of the mechanism; when the gear seat 125 rotates, the gear seat 125 drives the massage disc 5416 to rotate around the center of the fixed shaft 5417 through the massage head fixing seat 5415 to achieve the purpose of massage.
