[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0048] This utility model embodiment provides a massage device 1000, such as... Figure 1 - Figure 3 As shown, the massage device 1000 includes a housing 10, a rotary drive 20, a rotating disk 30, and a plurality of tentacles 40. The rotary drive 20 is installed inside the housing 10; the rotating disk 30 is installed inside the housing 10 and connected to the output end 21 of the rotary drive 20, and the rotating disk 30 is provided with a cam groove 31; the plurality of tentacles 40 surround the rotation axis of the rotating disk 30 (e.g., ...). Figure 3 As shown in Figure O, the tentacle 40 includes a pressure-applying part 41, a rotating part 42, and a transmission part 43. The pressure-applying part 41 is located outside the housing 10, and the transmission part 43 is located inside the housing 10 to cooperate with the cam channel 31. The rotating part 42 is located between the pressure-applying part 41 and the transmission part 43, and is connected to both the pressure-applying part 41 and the transmission part 43. In the rotation direction of the rotating disk 30, the rotating part 42 is rotatably connected to the housing 10. The rotary drive 20 drives the rotating disk 30 to rotate. The cam channel 31 cooperates with several transmission parts 43 and drives the corresponding rotating parts 42 to rotate, so that several pressure parts 41 move towards or away from the center of the rotating disk 30. This application solves the problem that the electromechanical structure of the existing massage device 1000 cannot achieve the massage technique and effect of manual massage, resulting in a poor user experience. This massage device 1000 can simulate the kneading massage technique of a human hand, resulting in a better massage effect.

[0049] Specifically, the output end 21 of the rotary drive 20 can drive the rotating disk 30 to rotate. The cam groove 31 of the rotating disk 30 cooperates with the transmission part 43 of the tentacle 40. The cam groove 31 can drive the transmission parts 43 of several tentacles 40 to move away from or closer to the center of the rotating disk 30. Since the rotating part 42 is rotatably connected to the housing 10, it restricts the movement path of the tentacle 40, so that the transmission part 43 can drive the rotating part 42 to rotate while moving. This causes the corresponding pressure part 41 to swing outward or inward. That is, several pressure parts 41 move away from or closer to the center of the rotating disk 30 to simulate the kneading massage technique of each finger of the human hand, providing users with a more human-like massage effect and improving the user's massage experience.

[0050] In this application, the rotary drive 20 can be a rotary motor or an electric cylinder, or of course a motion module capable of rotary motion, which is not limited here.

[0051] The number of tentacles 40 can be freely adjusted according to design requirements and is not limited here. For example, in this application, there are five tentacles 40, which are arranged around the rotation axis of the rotating disk 30.

[0052] The pressure-applying portion 41 of the tentacle 40 can have various shapes, which are not limited here. For example, to improve the massage effect, in this application, the pressure-applying portion 41 is S-shaped, and multiple pressure-applying portions 41 together enclose a massage space 44. The massage space 44 is used to accommodate the massage area of ​​the human body, such as the joint area. Thus, the arc-shaped pressure-applying portion 41 can better conform to the skin of the human body, facilitating the transmission of force and allowing the massage force to be more concentrated on the target area, thereby enhancing the massage effect.

[0053] In one embodiment, reference is made to Figure 4 - Figure 5 ,in, Figure 5 for Figure 4 The diagram shows the changing state of the rotating disk 30 after rotation. The cam channel 31 is a guide groove 311, located on the side of the rotating disk 30 facing away from the rotating drive member 20. The guide groove 311 surrounds the rotation axis of the rotating disk 30. The transmission part 43 is a pin 431, which is housed in the guide groove 311 and abuts against the side wall of the guide groove 311. With this arrangement, the side wall of the guide groove 311 abuts against the pin 431 to limit its position. During the rotation of the rotating disk 30, the guide groove 311 rotates with the rotating disk 30, changing the relative position of each pin 431 in the guide groove 311. The guide groove 311 allows each pin 431 to move along a specific motion trajectory, ultimately causing the pressure parts 41 of several tentacles 40 to open outward or retract inward, realistically simulating the massage technique of a human hand.

[0054] It is worth mentioning that by implementing the above embodiments, one guide groove 311 can control multiple tentacles 40, which not only improves the overall coordination of the movement of the structure, but also simplifies the structural design and reduces manufacturing costs.

[0055] Reference Figure 6 - Figure 8 ,in, Figure 6 - Figure 8 The diagrams show the sequential changes in the rotating state of the rotating disk 30. In one embodiment, the guide groove 311 includes at least two variable diameter groove segments 3111, which are connected end to end. The variable diameter groove segments 3111 extend in the rotation direction of the rotating disk 30, and the distance between the variable diameter groove segments 3111 and the center of the rotating disk 30 in the radial direction of the rotating disk 30 tends to gradually increase or decrease. With this configuration, the variable diameter groove section 3111 allows the transmission part 43 to move along a changing motion trajectory, so that when the transmission part 43 of each tentacle 40 cooperates with the guide groove 311, the relative position of the transmission part 43 of each tentacle 40 on the rotating disk 30 is not consistent. This allows each tentacle 40 to move asynchronously. That is, during use, some tentacles 40 have a tendency to gradually move inward, while at the same time, other tentacles 40 have a tendency to gradually move outward. This achieves a more realistic simulation of the massage technique of each finger applying pressure individually during a human hand massage, providing users with a better massage experience.

[0056] Reference Figure 4 - Figure 8 In one embodiment, the connection point of the two variable-diameter groove sections 3111 is arranged in an arc-shaped bend 3112. With this arrangement, when the transmission part 43 transitions to the connection point, the arc-shaped bend 3112 at the connection point increases the range of motion of the transmission part 43, thereby increasing the movement speed of the corresponding tentacle 40. This allows the transmission part 43 to move towards or away from the center of the rotating disk 30 in a shorter time. That is, when the tentacle 40 is at this connection point, it can quickly apply pressure or retract force to the massage contact part of the human body in a shorter time, further enhancing the massage effect.

[0057] Reference Figure 9In one embodiment, the rotating disk 30 includes a hollow shell 32 and a limiting plate. The hollow shell 32 is connected to the output end 21 of the rotary drive 20. A through-hole 321 is provided on the side of the hollow shell 32 facing away from the rotary drive 20. The limiting plate 33 is connected to the hollow shell 32 and located within the through-hole 321. The limiting plate 33 includes an outer peripheral wall surrounding the through-hole 321. The outer peripheral wall and the opening wall of the through-hole 321 together form the opening of the guide groove 311. Thus, the hollow shell 32 and the limiting plate together form the opening of the guide groove 311. On the one hand, this simplifies the manufacturing process, reduces the complexity of processing, and is beneficial for large-scale production; on the other hand, it facilitates the installation of multiple transmission parts 43 onto the guide groove 311, making installation more convenient.

[0058] In one embodiment, the pressure-applying part 41 is made of an elastic material. Thus, the elastic material of the pressure-applying part 41 has a certain deformation capability, allowing the user to change the shape of the pressure-applying part 41 to the massage area, thereby enabling the pressure-applying part 41 to make more full contact with the human body, facilitating the application of force to the massage area, and improving the massage experience. For example, the pressure-applying part 41 can be made of a soft tube.

[0059] In one embodiment, the pressure part 41, the transmission part 43 and the rotating part 42 are integrally formed to reduce the number of parts and facilitate assembly.

[0060] Reference Figure 10 - Figure 13 In one embodiment, the rotating part 42 includes a first rotating shaft 421 and a second rotating shaft 422, which are arranged opposite to each other in the rotation direction of the rotating disk 30. The housing 10 has a plurality of rotating structures 11 inside, each rotating structure 11 corresponding to the position of each rotating part 42. The first rotating shaft 421 and the second rotating shaft 422 of the rotating part 42 are rotatably connected to the corresponding rotating structure 11. This arrangement allows the tentacles 40 to be rotatably connected to the housing 10, and each rotating part 42 of the tentacles 40 has a first rotating shaft 421 and a second rotating shaft 422, improving the stability of the rotatable connection with the housing 10, reducing the shaking of the rotating part 42 during movement, and improving the overall reliability of the massage device 1000.

[0061] In one embodiment, the rotating structure 11 includes two first locking blocks 111 and two second locking blocks 112. In the rotation direction of the rotating disk 30, the two first locking blocks 111 are spaced apart, and the two second locking blocks 112 are respectively located on opposite sides of the two first locking blocks 111. The two first locking blocks 111 are respectively provided with a first locking groove 1111 and a second locking groove 1112, and the two second locking blocks 112 are respectively provided with a third locking groove 1121 and a fourth locking groove 1122. A first rotating shaft 421 is sequentially inserted through the first locking groove 1111 and the third locking groove 1121 to be limited and installed between the bottom of the first locking groove 1111 and the third locking groove 1121. A second rotating shaft 422 is sequentially inserted through the second locking groove 1112 and the fourth locking groove 1122 to be limited and installed between the bottom of the second locking groove 1112 and the fourth locking groove 1122. The first rotating shaft 421 is located between the bottom of the first slot 1111 and the third slot 1121, restricting its movement in both the horizontal and vertical directions. The first rotating shaft 421 can only rotate relative to the first slot 1111 and the third slot 1121. The second rotating shaft 422 is located between the bottom of the second slot 1112 and the fourth slot 1122, similarly restricting its movement in both the horizontal and vertical directions, allowing it to rotate only relative to the second slot 1112 and the fourth slot 1122. Thus, the rotating structure 11 is simple in design and ensures smooth operation of the massage device 1000. Specifically, an opening is provided between the two first locking blocks 111, and each tentacle 40 passes through the corresponding opening, with its rotating part 42 rotatably connected to the rotating structure 11 at this location.

[0062] Preferably, the bottoms of the first slot 1111, the second slot 1112, the third slot 1121, and the fourth slot 1122 are all arc-shaped and conform to the shape of the first rotating shaft 421 and the second rotating shaft 422. This makes the rotation of the rotating part 42 smoother and more continuous, preventing jamming during movement.

[0063] In one embodiment, the housing 10 includes an outer cover plate 12 and an inner cover plate 13. A plurality of tentacles 40 are respectively disposed on the outer cover plate 12 and the inner cover plate 13, such that the outer cover plate 12 and the inner cover plate 13 are located between the pressure application part 41 and the rotating disk 30. The inner cover plate 13 is located on the side of the outer cover plate 12 away from the pressure application part 41. A first locking block 111 is disposed on the side of the outer cover plate 12 facing the inner cover plate 13, and a second locking block 112 is disposed on the side of the inner cover plate 13 facing the outer cover plate 12. On the rotation axis of the rotating disk 30, the bottoms of the first locking groove 1111 and the third locking groove 1121 are opposite to each other, and the bottoms of the second locking groove 1112 and the fourth locking groove 1122 are opposite to each other. The outer cover plate 12 is detachably connected to the inner cover plate 13, so that the outer cover plate 12 and the inner cover plate 13 together form a plurality of rotating structures 11. Thus, the outer cover plate 12 is separated from the inner cover plate 13, and a number of tentacles 40 are inserted through the outer cover plate 12. The first pivot 421 and the second pivot 422 of each tentacles 40 can be respectively placed into the corresponding first locking block 111. Then, the inner cover plate 13 is fastened onto the outer cover plate 12. When the outer cover plate 12 and the inner cover plate 13 are connected, the second locking block 112 of the inner cover plate 13 can cooperate with the corresponding first locking block 111 to limit the installation of the first pivot 421 and the second pivot 422 of each tentacles 40. The assembly method is more efficient and convenient. It can also effectively protect the tentacles 40 from damage during the installation process and ensure the stability of the overall structure of the massage device 1000.

[0064] There are various ways to detach the outer cover plate 12 from the inner cover plate 13, such as snap-fit ​​connection or threaded connection. No limitation is made here on the method of detachment and connection.

[0065] Reference Figure 1 In one embodiment, the massage device 1000 further includes a vibrator 50, which is mounted on the side of the housing 10 facing the pressure application portion 41, and the pressure application portions 41 of a plurality of tentacles 40 are arranged around the vibrator 50. With this arrangement, the vibrator 50 applies vibrational force to the massage location during massage. Under the action of the vibrational force, blood circulation can be promoted, muscles relaxed, fatigue relieved, and the therapeutic effect of the massage improved, providing the user with a more comprehensive and detailed massage experience, increasing the sense of depth and comfort of the massage.

[0066] Reference Figure 3In one embodiment, the massage device 1000 further includes a battery 60 and a control circuit board 70. The control circuit board 70 and the battery 60 are mounted on the housing 10. The battery 60 is electrically connected to the control circuit board 70, and the control circuit board 70 is electrically connected to the vibrator 50 and the rotary drive 20 to control the operation of the vibrator 50 and the rotary drive 20. In this way, the battery 60 can be charged and stored, eliminating the need for the user to connect a power cord to the massage device 1000 for operation, making it more convenient to use. The control circuit board 70 controls the operation of the vibrator 50 and the rotary drive 20, allowing the user to select massage functions according to their needs.

[0067] Reference Figure 14 In one embodiment, the massage device 1000 further includes a soft silicone 80, which is wrapped around the pressure-applying part 41. Thus, the soft silicone 80 has a certain elasticity and softness. On the one hand, it can reduce the pressure and friction on the skin during massage and improve the comfort during the massage process. On the other hand, it can also improve the feel of the user holding the massage device 1000.

[0068] Preferably, the soft silicone 80 is also provided with protrusions 81, which can squeeze the skin, allowing the user to experience a deeper and more effective massage.
