[0032] Currently, there are many types of massage devices on the market, used to massage various parts of the body. Typical massage devices use a motor to drive the massage head to vibrate, thus massaging the user's head. A gearbox structure is usually installed between the motor and the massage head's transmission components, using gears within the gearbox structure to drive the module. However, existing gearbox structures suffer from high transmission losses, resulting in low transmission efficiency and negatively impacting the user experience.

[0033] Figure 1 This is a schematic diagram of the structure of the massage device 100 in one embodiment of the present invention. Figure 2 yes Figure 1 The exploded diagram.

[0034] Please see Figure 1 and Figure 2 As shown, in some embodiments, the massage device 100 may include a mounting base 2, a transmission assembly 3, a massage head 4, a jaw box structure 5, and a drive module 6. The transmission assembly 3 is movably mounted inside the mounting base 2, the massage head 4 is connected to the transmission assembly 3, and the drive module 6 drives the transmission assembly 3 to move via the jaw box structure 5, thereby causing the massage head 4 to oscillate and massage the human head.

[0035] In some embodiments, the mounting base 2 may be cylindrical. An installation space may be formed within the mounting base 2. The transmission assembly 3 can be rotatably mounted within the installation space.

[0036] It should be noted that in some other embodiments, the mounting base 2 may also be rectangular or other shapes.

[0037] In some embodiments, the massage device 100 may include a housing 1. The housing 1 may serve as the outer casing of the massage device 100. An installation space may be formed inside the housing 1. The mounting base 2, transmission assembly 3, massage head 4, jaw structure 5, and drive module 6 are all installed within the installation space. One end of the massage head 4 can extend out of the installation space to provide massage to the user. The housing 1 provides protection for the mounting base 2, transmission assembly 3, massage head 4, jaw structure 5, and drive module 6, preventing damage to the components within the housing 1.

[0038] In some embodiments, the housing 1 may include a housing body 11 and a handle portion 14 disposed on one side of the housing body 11. The housing body 11 may be connected to the handle portion 14. A first mounting area is provided inside the housing body 11. A second mounting area is formed inside the handle portion 14. The first mounting area and the second mounting area are connected.

[0040] In some embodiments, the housing 1 further includes a waterproof gasket 13. The waterproof gasket 13 may be annular. The waterproof gasket 13 may be disposed around the periphery of the decorative cover 12. The waterproof gasket 13 can seal the gap between the decorative cover 12 and the housing body 11, thereby preventing water from flowing into the installation space from outside the housing body 11.

[0042] Please see Figure 3 and Figure 4 As shown, in some embodiments, the transmission component 3 can be housed within the mounting base 2. The power output end of the drive module 6 can be connected to the transmission component 3. The power output end of the drive module 6 can drive the massage head 4 to oscillate via the transmission component 3, thereby achieving the kneading and massaging of the user's head.

[0043] In some embodiments, the transmission assembly 3 may include a transmission member 31. The transmission member 31 is rotatably disposed within the mounting base 2. The power output end of the drive module 6 may be connected to the transmission member 31. The power output end of the drive module 6 may drive the transmission member 31 to rotate within the mounting base 2.

[0044] In some embodiments, the transmission member 31 can be connected to the massage head 4. When the power output end of the drive module 6 drives the transmission member 31 to rotate, the transmission member 31 can drive the massage head 4 to swing, thereby enabling the massage head 4 to perform kneading and massaging for the user.

[0045] In some embodiments, multiple transmission members 31 may be provided. Each of the multiple transmission members 31 is rotatably disposed within the mounting base 2. The multiple transmission members 31 can be connected in a transmission manner. The power output end of the drive module 6 can be connected in a transmission manner to one of the transmission members 31. The power output end of the drive module 6 can drive one transmission member 31 to rotate, thereby enabling the multiple transmission members 31 to rotate.

[0046] In some embodiments, multiple transmission components 31 are connected end to end to form a ring structure. When the drive module 6 drives one transmission component 31 to rotate, the multiple transmission components 31 in the closed ring shape can maintain synchronous rotation, thereby improving the stability of rotation among the multiple transmission components 31.

[0047] In some embodiments, the transmission member 31 includes a transmission rod 312 and transmission wheels 313 disposed at both ends of the transmission rod 312. The transmission wheel 313 of one transmission member 31 can be transmittedly connected to the transmission wheel 313 of another adjacent transmission member 31. Thus, the power output end of the drive module 6 can drive one transmission member 31 to rotate, and through the transmission wheel 313 on the transmission member 31, it can be transmittedly connected to the transmission wheel 313 of another adjacent transmission member 31, thereby enabling multiple transmission members 31 to rotate within the mounting base 2 through the drive module 6.

[0048] In some embodiments, the transmission rod 312 is rod-shaped. The transmission rod 312 can rotate about its own axis. Both ends of the transmission rod 312 may be provided with transmission wheels 313. The transmission wheels 313 may be bevel gears, and the bevel gear of one transmission member 31 meshes with the bevel gear of another adjacent transmission member 31, thereby allowing the two transmission members 31 to mesh at an angle.

[0049] In some embodiments, multiple massage heads 4 may be provided. Multiple massage heads 4 may include multiple comb teeth 41. Multiple comb teeth 41 may be connected to multiple transmission members 31 respectively. The ends of the comb teeth 41 facing away from the mounting base 2 are used to contact the user's head. When the transmission member 31 rotates, the multiple comb teeth 41 can swing, thereby achieving a kneading and massaging effect on the user's head.

[0050] Please see Figure 4 As shown, in some embodiments, each of the multiple massage heads 4 may include a connecting seat 42. One end of the connecting seat 42 may be connected to multiple transmission components 31, and the other end of the connecting seat 42 may be connected to the comb teeth 41. When the drive module 6 drives the transmission components 31 to rotate, the transmission components 31 can drive the connecting seat 42 to rotate, thereby driving the comb teeth 41 to rotate.

[0051] In some embodiments, the transmission member 31 is provided with a fixing part 311. The multiple fixing parts 311 can be connected to multiple connecting seats 42 respectively, so that the multiple connecting seats 42 can be connected to the multiple transmission members 31.

[0052] Please see Figure 3 and Figure 4 As shown, in some embodiments, the tooth box structure 5 is located between the drive module 6 and the transmission component 3. The input end of the tooth box structure 5 is connected to the power output end of the drive module 6, and the output end of the tooth box structure 5 is connected to the transmission component 3. Thus, the power output end of the drive module 6 can drive the transmission component 3 to move through the transmission of the tooth box structure 5, thereby driving the comb teeth 41 on the massage head 4 to swing, thereby realizing the kneading of the user's head.

Figure 7 yes Figure 4 A cross-sectional view of the middle section of the structure. Figure 8 yes Figure 5 A schematic diagram of the middle part of the structure. Figure 9 yes Figure 8 The exploded diagram.

[0054] Please see Figures 4 to 9 As shown, in some embodiments, the gearbox structure 5 may include a worm gear 51. The worm gear 51 is rod-shaped. The power output end of the drive module 6 may pass through the worm gear 51, and the power output end of the drive module 6 is connected to the worm gear 51. The power output end of the drive module 6 can drive the worm gear 51 to rotate.

[0055] In some embodiments, the outer peripheral surface of the worm 51 is provided with helical teeth 511. The helical teeth 511 can be helically wound on the outer surface of the worm 51. When the power output end of the drive module 6 drives the worm 51 to rotate, the helical teeth 511 can rotate synchronously.

[0056] In some embodiments, the first reduction element 52 includes a worm gear 521. The rotation axis of the first reduction element 52 is in the same direction as that of the worm gear 521. The worm gear 521 is provided with helical teeth 5211 that mesh with the helical teeth 511 on the worm 51. The extending direction of the helical teeth 5211 is set at an angle to the rotation axis of the worm gear 521, so that the worm gear 521 can mesh with the worm 51. The axis of the worm gear 521 is perpendicular to the axis of the worm 51. Thus, the rotation direction of the power output end of the drive module 6 can be changed by using the worm gear 521 and the worm 51.

[0057] In some embodiments, the surface of the worm 51 may be provided with two parallel threads, which are respectively wound around the outer surface of the worm 51, and the helical directions of the two threads are opposite. The two threads are arranged at intervals. Thread teeth 511 are formed between the two threads. As a result, at the same input rotational speed of the drive module 6, the output rotational speed of the two helical teeth 511 is faster, thereby improving the transmission efficiency between the drive module 6 and the first reduction member 52.

[0058] Please see Figure 8 As shown, in some embodiments, the angle between the extending direction of the helical tooth 5211 and the axis of the worm wheel 521 is 10°. This allows the helical tooth 5211 to mesh with the helical tooth 511 on the worm 51, thereby realizing the transmission from the worm 51 to the worm wheel 521, and thus realizing the change of direction during transmission.

[0059] It should be noted that in some other embodiments, the angle between the extending direction of the helical tooth 5211 and the axis of the worm gear 521 can also be other sizes.

[0060] In some embodiments, the ratio of the number of helical teeth 511 to the number of oblique teeth 5211 can be 2:28. This reduces the speed of the transmission from the drive module 6 to the first reducer 52, thereby preventing the massage head 4 from swinging too fast due to the excessive rotation speed of the drive module 6, which in turn prevents the comb teeth 41 from swinging too fast and thus affects the massage effect of the massage device 100.

[0061] It should be noted that in some other embodiments, the surface of the worm 51 may be provided with one or more helical teeth 511, and the number of helical teeth 511 is not limited here.

[0062] It should also be noted that in some other embodiments, the ratio of the number of helical teeth 511 to the number of helical teeth 5211 can be other ratios, as long as the number of helical teeth 511 is less than the number of helical teeth 5211.

[0063] Please see Figures 4 to 9 As shown, in some embodiments, the gearbox structure 5 may include a first reduction element 52. The first reduction element 52 may be disposed between the transmission assembly 3 and the worm gear 51, and may be connected to the transmission assembly 3 and the worm gear 51 respectively, thereby realizing the transmission from the worm gear 51 to the transmission assembly 3.

[0064] In some embodiments, the first reduction component 52 includes a first gear 522. The first gear 522 is connected to the worm gear 521. The first gear 522 is located on one side of the worm gear 521. The first gear 522 and the worm gear 521 are coaxially arranged. When the power output end of the drive module 6 drives the worm 51 to rotate, the helical teeth 511 on the worm 51 can drive the helical teeth 5211 on the worm gear 521 to rotate, thereby driving the first gear 522 to rotate.

[0065] In some embodiments, the first gear 522 and the worm gear 521 can be integrally formed double-layer gears. Therefore, the first gear 522 and the worm gear 521 can be produced using a single mold, thereby reducing the production cost of the first gear 522 and the worm gear 521 and improving their production efficiency.

[0066] Please see Figures 4 to 9 As shown, in some embodiments, the gearbox structure 5 may include a second reduction member 53. The second reduction member 53 is disposed between the first reduction member 52 and the transmission assembly 3, and is drively connected to both the first reduction member 52 and the transmission assembly 3.

[0067] In some embodiments, the second speed reducer 53 includes a second gear 531. The second gear 531 can mesh with the first gear 522, so that when the worm gear 521 drives the first gear 522 to rotate, the first gear 522 can drive the second gear 531 to rotate, thereby realizing the rotation of the second speed reducer 53.

[0068] In some embodiments, the first gear 522 is provided with a first tooth portion 5221. Multiple first tooth portions 5221 are provided. Multiple first gears 522 are spaced apart on the periphery of the first gear 522. The extending direction of the first tooth portions 5221 is parallel to the rotation axis direction of the first gear 522, thus making the first gear 522 a spur gear. The second gear 531 is provided with a second tooth portion 5311. Multiple second tooth portions 5311 are provided. Multiple second gears 531 are spaced apart on the periphery of the second gear 531. The extending direction of the second tooth portions 5311 is parallel to the rotation axis direction of the second gear 531, thus making the second gear 531 a spur gear. Therefore, by utilizing the spur tooth meshing between the first gear 522 and the second gear 531, frictional losses during transmission are reduced, resulting in low transmission losses between the first gear 522 and the second gear 531, thereby improving the transmission efficiency of the gearbox structure 5.

[0069] In some embodiments, the number of helical teeth 5211 on the worm gear 521 is greater than the number of teeth on the first tooth portion 5221 of the first gear 522. The diameter of the worm gear 521 is larger than the diameter of the first gear 522. Thus, when the power output end of the drive module 6 drives the worm 51 to rotate, the worm 51 can drive the worm gear 521 to rotate, thereby causing the first gear 522 to rotate, and then causing the second gear 531 to rotate. Since the number of helical teeth 5211 on the worm gear 521 is greater than the number of teeth on the first tooth portion 5221 of the first gear 522, the first reducer 52 can reduce the transmission between the worm 51 and the second reducer 53, thereby avoiding the massage head 4 from swinging too fast due to the excessive rotation speed of the drive module 6, which would cause the comb teeth 41 to swing too fast and affect the massage effect of the massage device 100.

[0070] In some embodiments, the number of first teeth 5221 on the first gear 522 is less than the number of second teeth 5311 on the second gear 531. Through the meshing of the first gear 522 and the second gear 531, when the first reducer 52 drives the second reducer 53 to rotate, the rotational speed of the second reducer 53 is less than the rotational speed of the first reducer 52, thereby achieving speed reduction from the first reducer 52 to the second reducer 53. Thus, the transmission from the drive module 6 to the massage head 4 can achieve speed reduction, thereby preventing the massage head 4 from oscillating too quickly due to the excessive rotational speed of the drive module 6, which would cause the comb teeth 41 to oscillate too quickly and affect the massage effect of the massage device 100.

[0071] In some embodiments, the ratio of the number of first teeth 5221 to the number of second teeth 5311 may be 10:32.

[0072] It should also be noted that in some other embodiments, the ratio of the number of the first tooth 5221 to the number of the second tooth 5311 can be other ratios, as long as the number of the first tooth 5221 is less than the number of the second tooth 5311.

[0073] In some embodiments, the second reducer 53 further includes a third gear 532. The third gear 532 is connected to the second gear 531. The third gear 532 is located on one side of the second gear 531. The third gear 532 and the second gear 531 are coaxially arranged. The third gear 532 can be connected to the transmission assembly 3 for transmission. When the power output end of the drive module 6 drives the worm 51 to rotate, the helical teeth 511 on the worm 51 can drive the helical teeth 5211 on the worm wheel 521 to rotate, thereby driving the first reducer 52 and the second reducer 53 to rotate, so that the third gear 532 can drive the transmission assembly 3 to move, thereby driving the massage head 4 to swing, realizing the kneading and grasping of the user.

[0074] In some embodiments, the third gear 532 is provided with a third tooth 5321. Multiple third teeth 5321 are provided. Multiple third gears 532 are spaced apart on the periphery of the third gear 532. The extending direction of the third teeth 5321 is parallel to the rotation axis direction of the third gear 532, thus making the third gear 532 a spur gear. Therefore, by utilizing the meshing of the third teeth 5321 on the third gear 532 with the transmission assembly 3, frictional losses during transmission are reduced, resulting in low transmission losses between the third gear 532 and the transmission assembly 3, thereby further improving the transmission efficiency of the gearbox structure 5.

[0075] In some embodiments, the number of second teeth 5311 on the second gear 531 is greater than the number of teeth on the third teeth 5321 on the second gear 531. The diameter of the second gear 531 is greater than the diameter of the third gear 532. Thus, when the power output end of the drive module 6 drives the worm 51 to rotate, the worm 51 can drive the worm wheel 521 to rotate, thereby causing the first gear 522 to rotate, and then causing the second gear 531 and the third gear 532 to rotate. Since the number of second teeth 5311 on the second gear 531 is greater than the number of teeth on the third teeth 5321 on the second gear 531, the second reducer 53 can reduce the transmission between the first reducer 52 and the transmission assembly 3, thereby avoiding the massage head 4 from swinging too fast due to the excessive rotation speed of the drive module 6, which would cause the comb teeth 41 to swing too fast and affect the massage effect of the massage device 100.

[0076] In some embodiments, the second gear 531 and the third gear 532 can be integrally formed double-layer gears. Therefore, the second gear 531 and the third gear 532 can be produced using a single mold, thereby reducing the production cost of the second gear 531 and the third gear 532 and improving their production efficiency.

[0077] In some embodiments, the axial length of the first gear 522 is greater than the axial length of the worm gear 521. The axial length of the third gear 532 is greater than the axial length of the second gear 531. The first gear 522 is disposed on the first side of the worm gear 521. The third gear 532 is disposed on the second side of the second gear 531. The first side and the second side are opposite sides with opposite directions. Simultaneously, the diameter of the first gear 522 is smaller than the diameter of the worm gear 521, and the diameter of the third gear 532 is smaller than the diameter of the second gear 531. Therefore, the first reduction element 52 and the second reduction element 53 are staggered, avoiding mutual interference, resulting in a more balanced gravity distribution, more stable force transmission between them, improved reliability, and more efficient space utilization.

[0078] In some embodiments, the ratio of the axial length of the first gear 522 to the axial length of the worm gear 521 ranges from 2 to 4.

[0079] In some embodiments, the ratio of the axial length of the third gear 532 to the axial length of the second gear 531 is in the range of 2 to 4.

[0080] In some embodiments, the first gear 522 and the second gear 531 can mesh along the length direction of the handle portion 14, so that the first reducer 52 and the second reducer 53 can be installed along the length direction of the handle portion 14, thereby making reasonable use of the space along the length direction of the handle portion 14.

[0081] In some embodiments, the ratio of the axial length of the turbine 521 to the axial length of the second gear 531 is in the range of 0.8 to 1.2, so that the dimensions between the turbine 521 and the second gear 531 are similar, thereby making full use of the space within the gearbox structure 5 after the first reducer 52 and the second reducer 53 are installed.

[0082] Please see Figures 4 to 9As shown, in some embodiments, the gearbox structure 5 further includes a third reduction component 54. The third reduction component 54 includes a fourth gear 541 and a fifth gear 542 connected together. The fourth gear 541 is located on one side of the fifth gear 542. The fourth gear 541 and the fifth gear 542 are coaxially arranged. The fourth gear 541 can be driven to the third gear 532. The fifth gear 542 can be driven to the transmission assembly 3. When the power output end of the drive module 6 drives the worm gear 51 to rotate, the helical teeth 511 on the worm gear 51 can drive the helical teeth 5211 on the worm wheel 521 to rotate, thereby driving the first reduction component 52 and the second reduction component 53 to rotate, so that the third gear 532 can drive the fifth gear 542 to rotate through the fourth gear 541, thereby driving the transmission assembly 3 to move, so as to drive the massage head 4 to swing, realizing the kneading of the user.

[0083] In some embodiments, the fourth gear 541 is provided with a fourth tooth 5411. Multiple fourth tooth portions 5411 are provided. Multiple fourth gears 541 are spaced apart on the periphery of the fourth gear 541. The extending direction of the fourth tooth portions 5411 is parallel to the rotation axis direction of the fourth gear 541, thus making the fourth gear 541 a spur gear. Therefore, by utilizing the meshing between the fourth tooth portions 5411 on the fourth gear 541 and the third tooth portions 5321 on the third gear 532, frictional losses during transmission are reduced, resulting in low transmission losses between the third gear 532 and the fourth gear 541, thereby improving the transmission efficiency of the gearbox structure 5.

[0084] In some embodiments, the number of fourth teeth 5411 on the fourth gear 541 is greater than the number of third teeth 5321 on the third gear 532. Through the meshing of the third gear 532 and the fourth gear 541, when the second reducer 53 drives the third reducer 54 to rotate, the rotational speed of the third reducer 54 is less than the rotational speed of the second reducer 53, thereby achieving speed reduction from the second reducer 53 to the third reducer 54. Thus, the transmission from the drive module 6 to the massage head 4 can achieve speed reduction, thereby preventing the massage head 4 from oscillating too quickly due to the excessive rotational speed of the drive module 6, which would cause the comb teeth 41 to oscillate too quickly and affect the massage effect of the massage device 100.

[0085] In some embodiments, the ratio of the number of the third tooth 5321 to the number of the fourth tooth 5411 is 10:20.

[0086] It should also be noted that in some other embodiments, the ratio of the number of the third tooth 5321 to the number of the fourth tooth 5411 can be other ratios, as long as the number of the third tooth 5321 is less than the number of the fourth tooth 5411.

[0087] In some embodiments, the fifth gear 542 is provided with a fifth tooth 5421. Multiple fifth tooth portions 5421 are provided. Multiple fifth gears 542 are spaced apart on the periphery of the fifth gear 542. The extending direction of the fifth tooth portions 5421 is parallel to the rotation axis direction of the fifth gear 542, thus making the fifth gear 542 a spur gear. Therefore, by utilizing the fifth tooth portions 5421 on the fifth gear 542 to transmit power with the transmission assembly 3, frictional losses during transmission are reduced, resulting in low transmission losses between the fifth gear 542 and the transmission assembly 3, thereby improving the transmission efficiency of the gearbox structure 5.

[0088] In some embodiments, the number of fifth teeth 5421 on the fifth gear 542 is less than the number of fourth teeth 5411 on the fourth gear 541. The diameter of the fourth gear 541 is larger than the diameter of the fifth gear 542. Therefore, when the power output end of the drive module 6 drives the worm gear 51 to rotate, the worm gear 51 can drive the worm wheel 521 to rotate, thereby causing the first gear 522 to rotate, which in turn causes the second gear 531 and the third gear 532 to rotate, which in turn drives the fourth gear 541 and the fifth gear 542 to rotate. Since the number of fifth teeth 5421 on the fifth gear 542 is less than the number of fourth teeth 5411 on the fourth gear 541, the third reducer 54 can reduce the transmission speed between the second reducer 53 and the transmission assembly 3, thereby preventing the massage head 4 from swinging too fast due to the excessive rotation speed of the drive module 6, which would affect the massage effect of the massage device 100.

[0089] In some embodiments, the fourth gear 541 and the fifth gear 542 can be integrally formed double-layer gears. Therefore, the fourth gear 541 and the fifth gear 542 can be produced using a single mold, thereby reducing the production cost of the fourth gear 541 and the fifth gear 542 and improving their production efficiency.

[0090] In some embodiments, the third reduction member 54 may further include a partition portion 543. The partition portion 543 may be disposed between the fourth gear 541 and the fifth gear 542. The partition portion 543 can be used to separate the fourth gear 541 and the fifth gear 542, thereby improving the success rate of the fourth gear 541 and the fifth gear 542 in demolding.

[0091] It should be noted that in some other embodiments, the first reduction member 52 may also include a partition portion 543. The partition portion 543 may be disposed between the worm gear 521 and the first gear 522 to improve the success rate of demolding of the worm gear 521 and the first gear 522.

[0092] It should also be noted that in some other embodiments, the second reduction member 53 may also include a partition portion 543. The partition portion 543 may be disposed between the second gear 531 and the third gear 532 to improve the success rate of demolding between the second gear 531 and the third gear 532.

[0093] Please see Figure 4 As shown, in some embodiments, the massage device 100 may include a gearbox 55. A first reducer 52, a second reducer 53, and a third reducer 54 are rotatably mounted on the gearbox 55. Thus, the gearbox 55 enables the first reducer 52, the second reducer 53, and the third reducer 54 to form a transmission module, thereby improving the modularity of the massage device 100.

[0094] In some embodiments, a rotating hole 557 is provided on the side wall of the gearbox 55. The first reduction member 52 is rotatably disposed at the rotating hole 557. Rotating portions 552 are respectively provided on opposite sides of the rotating hole 557. Rotating grooves 553 are respectively provided in the two rotating portions 552, and the two ends of the first reduction member 52 are respectively rotatably disposed in the two rotating grooves 553. Thus, the stability of the first reduction member 52 rotating on the gearbox 55 can be improved by using the two rotating grooves 553.

[0095] Please see Figure 3 and Figure 4 As shown, in some embodiments, the transmission assembly 3 further includes a linkage 32. The linkage 32 can be connected to a transmission component 31. The third gear 532 can be connected to the linkage 32 for transmission. The power output end of the drive module 6 can drive the third gear 532 to rotate, thereby driving the linkage 32 to swing, which in turn drives the transmission component 31 to rotate, thereby driving the massage head 4 to swing through the transmission component 31, so that the massage head 4 can be used to knead and massage the user.

[0096] Figure 10 yes Figure 4 A schematic diagram of the middle section.

[0097] Please see Figures 2 to 10 As shown, in some embodiments, the massage device 100 includes an adapter 7. The adapter 7 may be disposed between the drive module 6 and the linkage 32. The third gear 532 can drive the linkage 32 to swing through the drive adapter 7, thereby realizing the rotation of the transmission member 31, causing the multiple comb teeth 41 to swing, thus realizing the massage for the user.

[0098] In some embodiments, the adapter 7 may include an adapter body 71 and an output portion 72 disposed on the adapter body. The axis of the output portion 72 is parallel to the axis of the adapter body 71. The axis of the output portion 72 is offset from the axis of the adapter body 71, and the output portion 72 is drivenly connected to the linkage 32. The third gear 532 is drivenly connected to the adapter body 71. The power output end of the drive module 6 can drive the third gear 532 to rotate, thereby driving the adapter 7 to rotate around the axis of the adapter body 71, so that the output portion 72 can drive the linkage 32 to oscillate back and forth between a first direction and a second direction, and the first direction and the second direction are opposite, thereby causing the transmission member 31 to drive the comb teeth 41 to oscillate back and forth, thereby realizing the grasping and kneading of the user's head.

[0099] The axis of rotation of the adapter 7 is offset from the axis of the output part 72. The adapter 7 rotates around the axis of the adapter body 71. The output part 72 can drive the linkage 32 to swing back and forth between the first direction and the second direction, thereby causing the comb teeth 41 to swing back and forth to achieve kneading. The adapter 7 makes the swing of the linkage 32 smoother and more fluid, thereby improving the kneading effect of the massage device 100 and improving the user experience.

[0100] In some embodiments, the adapter 7 further includes an input section 73. The input section 73 is located on the side of the adapter body 71 away from the output section 72. The input section 73 is coaxially arranged with the adapter body 71. The axis of the input section 73 is offset from the axis of the output section 72. The power output end of the drive module 6 is connected to the input section 73, and the power output end of the drive module 6 can drive the adapter 7 to rotate about the axis of the adapter body 71 through the input section 73.

[0101] In some embodiments, the input section 73 can be integrally formed with the adapter body 71. This allows the input section 73 to directly drive the adapter 7 to rotate about the axis of the adapter body 71, thereby improving the transmission efficiency between the input section 73 and the adapter 7.

[0102] In some embodiments, the input section 73 is provided with a first connecting wheel 74, which is connected to the input section 73. The first connecting wheel 74 is coaxially arranged with the input section 73. The massage device 100 includes a second connecting wheel 57, which is rotatably disposed within the gearbox 55. The second connecting wheel 57 can be disposed between the fifth gear 542 and the first connecting wheel 74. The second connecting wheel 57 can be drivenly connected to the first connecting wheel 74. The first connecting wheel 74 and the second connecting wheel 57 are drivenly connected. Thus, the power output end of the drive module 6 can drive the second connecting wheel 57 to rotate, thereby driving the first connecting wheel 74 to rotate and the input section 73 to rotate, thereby driving the linkage 32 to oscillate back and forth between the first direction and the second direction, thereby causing the comb teeth 41 to oscillate back and forth to achieve kneading.

[0103] In some embodiments, the first connecting wheel 74 and the second connecting wheel 57 may also be gears. The fifth gear 542, the second connecting wheel 57, and the first connecting wheel 74 have the same number of teeth.

[0104] In some embodiments, a swing space 56 is provided on one side of the gearbox 55. When the power output end of the drive module 6 can drive the second connecting wheel 57 to rotate, thereby driving the first connecting wheel 74 to rotate and the input part 73 to rotate, the output part 72 can drive the linkage 32 to swing within the swing space 56.

[0105] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0106] This utility model provides a dental gearbox structure 5 and a massage device 100. The dental gearbox structure 5 includes a worm gear 51, a first reduction component 52, and a second reduction component 53. The first reduction component 52 includes a connected worm wheel 521 and a first gear 522. The helical teeth 5211 of the worm wheel 521 mesh with the helical teeth 511 on the worm gear 51. The second reduction component 53 includes a connected second gear 531 and a third gear 532. The second gear 531 meshes with the first gear 522; the third gear 532 is connected to the massage head 4. The extension direction of the first tooth portion 5221 on the first gear 522 is parallel to the rotation axis of the first gear 522; the extension direction of the second tooth portion 5311 on the second gear 531 is parallel to the rotation axis of the second gear 531; and the extension direction of the third tooth portion 5321 on the third gear 532 is parallel to the rotation axis of the third gear 532. Therefore, the first gear 522, the second gear 531, and the third gear 532 are all spur gears, which reduces the frictional loss during transmission between the first gear 522 and the second gear 531, as well as between the third gear 532 and the transmission component 3 of the massage device 100. This results in low transmission loss between the first gear 522 and the second gear 531, as well as between the third gear 532 and the transmission component 3 of the massage device 100, thereby improving the transmission efficiency of the gearbox structure 5 and enhancing the user experience.
