[0053] Embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0054] The embodiments of the present application are described below with reference to the accompanying drawings. Figures 1-13 The neck massager 100 according to the embodiments of the present application is described below, including the intermediate support 10, the adjusting assembly 20, and the massage head assembly 30.

[0055] Referring to Figures 1-2 and in combination with Figure 5 and Figure 6 The intermediate support 10 has an accommodating space 15 inside, the adjusting assembly 20 is movably installed on the intermediate support 10, at least part of the adjusting assembly 20 is arranged in the accommodating space 15, and the massage head assembly 30 is connected to the side of the adjusting assembly 20 facing the human neck, so that the adjusting assembly 20 and the massage head assembly 30 move together. The adjusting assembly 20 includes a damping member 21, the damping member 21 is in contact with the intermediate support 10, the damping member 21 can be compressed and deformed by the intermediate support 10, and the damping member 21 can stay at any position of the intermediate support 10 within the movable range of the adjusting assembly 20 to ensure that the massage head assembly 30 can stay at any position of the intermediate support 10.

[0056] According to the neck massager 100 of the embodiments of the present application, when the user applies a force to the massage head assembly 30, the adjusting assembly 20 and the massage head assembly 30 can move together. The damping member 21 can be compressed and deformed by the intermediate support 10, so that the contact surface of the damping member 21 and the intermediate support 10 can generate a mutual pressure. At the same time, the damping member 21 and the intermediate support 10 can generate a relative movement, and the contact surface of the damping member 21 and the intermediate support 10 can generate a certain friction force to hinder the relative movement of the damping member 21 and the intermediate support 10. In addition, when the damping member 21 and the intermediate support 10 have a relative movement trend, the contact surface can also generate a certain friction force to hinder the relative movement trend of the damping member 21, so that the massage head assembly 30 can stay at any adjustable position of the intermediate support 10, and the massage head assembly 30 can stay at any position of the intermediate support 10 to realize stepless adjustment of the neck massager 100. In addition, the user can adjust the position of the massage head assembly 30 to ensure the fit of the massage head assembly 30 with the human neck, improve the massage effect, ensure the comfort of the massage, and the user can adjust the position of the massage head assembly 30 according to the own needs to improve the massage range of the neck massager 100, and the adaptability is good.

[0057] For example, the damping member 21 can be made of soft, elastic and compressible material, such as silicone and rubber. The soft damping member 21 can effectively absorb the vibration caused by movement, and there is no collision during the whole process, so as to avoid the generation of noise, thereby achieving the silent effect when the user adjusts the massage head assembly 30.

[0058] In some embodiments, the intermediate support 10 can have a sliding groove (not shown in the figure) extending along the extension direction of the intermediate support 10, and the adjustment assembly 20 is slidable along the extension direction of the sliding groove (for example, along the left-right direction of the intermediate support 10). In this way, when the user adjusts the massage head assembly 30, the intermediate support 10 and the adjustment assembly 20 can have sliding friction or relative sliding tendency, and the damping member 21 can hinder the relative sliding or relative sliding tendency. Through the arrangement of the sliding groove, the adjustment of the massage head assembly 30 can be more smooth. Of course, in other examples, the adjustment assembly 20 can have various movement modes such as rotation, and the adjustment assembly 20 can move back and forth. Figure 3 and Figure 4 In this way, when the user adjusts the massage head assembly 30, the intermediate support 10 and the adjustment assembly 20 can have sliding friction or relative sliding tendency, and the damping member 21 can hinder the relative sliding or relative sliding tendency. Through the arrangement of the sliding groove, the adjustment of the massage head assembly 30 can be more smooth. Of course, in other examples, the adjustment assembly 20 can have various movement modes such as rotation, and the adjustment assembly 20 can move back and forth.

[0059] In some examples, as shown in Figures 1-3 The neck massage device 100 further comprises a synchronous assembly 40, and the massage head assembly 30 can be multiple, and the multiple massage head assemblies 30 are connected with the synchronous assembly 40. The multiple massage head assemblies 30 comprise a first massage head assembly 31, and when the first massage head assembly 31 moves, the other massage head assemblies 30 can move the same or different distance as the first massage head assembly 31. Through the arrangement of the synchronous assembly 40, the synchronous movement of the multiple massage head assemblies 30 can be realized, and the user does not need to adjust the multiple massage head assemblies 30 respectively, which reduces the operation steps and improves the adjustment efficiency. In the description of the present application, the meaning of "multiple" is two or more.

[0060] In some specific embodiments of the present application, the multiple massage head assemblies 30 can further comprise a second massage head assembly 32, and the first massage head assembly 31 and the second massage head assembly 32 are symmetrically arranged along the extension direction of the intermediate support 10, so as to ensure that the user's neck has the same massage experience on both sides. Among them, the first massage head assembly 31 moves in a direction away from the second massage head assembly 32, and the second massage head assembly 32 moves in a direction away from the first massage head assembly 31. Alternatively, the first massage head assembly 31 moves in a direction towards the second massage head assembly 32, and the second massage head assembly 32 moves towards the first massage head assembly 31. In this way, the two massage head assemblies 30 can be symmetrically arranged at all times to ensure good massage effect and good fit. Of course, in other implementations, the first massage head assembly 31 and the second massage head assembly 32 can also move synchronously in the same direction to adapt to the needs of the user.

[0061] In some examples, as shown in Figure 3 and Figure 4 The synchronization assembly 40 includes a first traction line 41, a second traction line 42, and a collection rod 43, the first traction line 41 and the second traction line 42 are wound at different positions of the collection rod 43, for example, a part of the first traction line 41 is wound at the lower end of the collection rod 43 as shown in Figure 3 and Figure 4 The part of the second traction line 42 is wound at the upper end of the collection rod 43 as shown in Figure 3 and Figure 4 The winding direction of the first traction line 41 is opposite to that of the second traction line 42.

[0062] When the first massage head assembly 31 and the second massage head assembly 32 move away from each other, the collection rod 43 rotates, the first traction line 41 is released from the collection rod 43, and the second traction line 42 is wound to the collection rod 43 to realize the synchronous separation of the two massage head assemblies. When the first massage head assembly 31 and the second massage head assembly 32 move towards each other, the collection rod 43 rotates, the first traction line 41 is wound to the collection rod 43, and the second traction line 42 is released from the collection rod 43 to realize the synchronous folding of the two massage head assemblies.

[0063] Through the arrangement of the first traction line 41, the second traction line 42, and the collection rod 43, the transmission of force can be realized, and the synchronous movement of the two massage head assemblies 30 can be effectively realized. At the same time, the first traction line 41 and the second traction line 42 with opposite winding directions arranged in this way can keep the two traction lines in a taut state at all times to prevent interference with other parts, thereby ensuring the reliability of the synchronization assembly 40. In addition, the first traction line 41 and the second traction line 42 are made of flexible material, which can adapt to the deformation of the middle support 10. When the user performs twisting, rotating, and other actions, the middle support 10 will deform. The arrangement can avoid the influence of the deformation of the middle support 10 on the synchronization assembly 40, thereby ensuring the synchronous adjustment effect and reliability of the multiple massage head assemblies 30. It should be noted that both ends of the first traction line 41 and the second traction line 42 can be reserved with free ends.

[0064] For example, the parts of the first traction line 41 on both sides of the collection rod 43 are wound on the collection rod 43 in the clockwise direction (for example, the arrow direction shown in the view angle as shown in Figure 3 and Figure 4 The parts of the second traction line 42 on both sides of the collection rod 43 are wound on the collection rod 43 in the counterclockwise direction (for example, the arrow direction shown in the view angle as shown in

[0065] As shown in Figure 3 and Figure 4As shown, the synchronous assembly 40 can further comprise two reversing members 440, which are respectively arranged at two sides of the synchronous assembly 40. One end of the second traction line 42 is installed on one of the reversing members 440 to change the direction of the one end of the second traction line 42, and the other end of the second traction line 42 is installed on the other reversing member 440 to change the direction of the other end of the second traction line 42. By means of the two reversing members 440, the extension directions of the two ends of the second traction line 42 can be changed by the principle of pulley, so as to apply force and realize the synchronous movement of the plurality of massage head assemblies 30. For example, one of the two reversing members 440 can be a first reversing member 441, and the other can be a second reversing member 442. In combination with Figure 4 and Figure 5 , the reversing member 440 on the left side can be the first reversing member 441, and the reversing member 440 on the right side can be the second reversing member 442.

[0066] The two free ends of the second traction line 42 can change directions through the two reversing members 440. After changing the directions, the two free ends of the second traction line 42 are respectively connected to the first massage head assembly 31 and the second massage head assembly 32. When the first massage head assembly 31 moves, the two ends of the second traction line 42 are wound or released on the collecting rod 43 to drive the second massage head assembly 32 to move.

[0067] In some embodiments, as shown in Figure 10 , the reversing member 440 can comprise a matching groove 445, and the second traction line 42 is arranged in the matching groove 445 to change the extension direction of the second traction line 42, so that the second traction line 42 can slide in the matching groove 445, the friction is low, and the smoothness of the movement of the massage head assembly 30 can be ensured. For example, the matching groove 445 comprises a first matching groove 443 and a second matching groove 444 arranged at intervals, and the second traction line 42 is arranged in the first matching groove 443 and the second matching groove 444 to change the extension direction of the second traction line 42. In this way, the second traction line 42 can slide in the first matching groove 443 and the second matching groove 444, and the extension direction of the second traction line 42 can be changed. For example, the first matching groove 443 and the second matching groove 444 can be arranged along, for example Figure 10The first matching groove 443 and the second matching groove 444 are arranged in the middle of the second reversing piece 442. The groove width of the first matching groove 443 and the second matching groove 444 can be 1mm-2mm larger than the diameter of the second traction line 42, and the groove depth is at least 5mm larger than the diameter of the second traction line 42, so that when the second traction line 42 moves in the first matching groove 443 and the second matching groove 444, it can not be affected by the neck massage instrument 100 to shake and deform and be separated from the first matching groove 443 and the second matching groove 444, ensuring the assembly reliability. The first reversing piece 441 can be the same structure as the second reversing piece 442, so that both ends of the second traction line 42 can be turned in the direction by the two matching grooves 445.

[0068] Referring to Figure 3 , Figure 4 and Figure 8 , the synchronous assembly 40 further comprises at least one traction line guide 45 arranged between the collecting rod 43 and the adjusting assembly 20. The traction line guide 45 has a first guide groove 451 and a second guide groove 452, the first traction line 41 passes through the first guide groove 451 to change the extension direction of the first traction line 41, and the second traction line 42 passes through the second guide groove 452 to change the extension direction of the second traction line 42. Through the arrangement of the traction line guide 45, the first traction line 41 and the second traction line 42 can be limited and at the same time be spaced apart, preventing the first traction line 41 and the second traction line 42 from being wound together, ensuring the reliability of the synchronous assembly 40.

[0069] At the same time, after the first traction line 41 and the second traction line 42 are installed in the intermediate support 10, the extension direction can have a certain angle relative to the horizontal direction, so as to adapt to the shape of the intermediate support 10. Through the arrangement of the traction line guide 45, it can be prevented that after the first traction line 41 and the second traction line 42 are installed in the intermediate support 10, the extension direction is a straight line, and the straight line is connected as a broken line connection, and the bending part just avoids part of the components, which can prevent the first traction line 41 and the second traction line 42 from interfering with the intermediate support 10 or other structures of the intermediate support 10.

[0070] In some examples, the cross section of the first guide slot 451 and the second guide slot 452 is square, the diameter of the first traction line 41 is D1, the width of the first guide slot 451 is D2, and the depth of the first guide slot 451 is D3, wherein D1, D2, and D3 satisfy the relationship: 1mm≤D2-D1≤2mm, and D3-D1≥5mm; and / or the diameter of the second traction line 42 is D4, the width of the second guide slot 452 is D5, and the depth of the second guide slot 452 is D6, wherein D4, D5, and D6 satisfy the relationship: 1mm≤D5-D4≤2mm, and D6-D1≥5mm. In this way, the first traction line 41 and the second traction line 42 can be prevented from being disengaged from the first guide slot 451 and the second guide slot 452 when the neck massager 100 vibrates or the user moves the massage head assembly 30, thereby improving the structural stability of the synchronous assembly 40.

[0071] In some examples, the diameter of the first traction line 41 is D1, the diameter of the second traction line 42 is D4, and the first traction line 41 and the second traction line 42 can be made of nylon, wherein D1 and D4 satisfy the relationship: 0.2mm≤D1≤0.5mm, and 0.2mm≤D4≤0.5mm. 1、 D4 satisfy the relationship: 0.2mm≤D 、 ≤D4≤0.5mm. Nylon has the characteristics of high strength, low elongation, and wear resistance, so that the first traction line 41 and the second traction line 42 have good structural stability and reliability, and good tensile strength and high tension, to ensure that the synchronous assembly 40 has good structural reliability and can facilitate the transmission of force, so that the plurality of massage head assemblies 30 can move synchronously.

[0072] In some examples, as shown in Figure 8 the traction line guide 45 can include at least one protruding portion 453 and a main body portion 454, the protruding portion 453 has a threaded hole, and the other has a protruding column 12, the protruding column 12 is threadedly connected with the threaded hole to increase the contact area between the intermediate support 10 and the traction line guide, and to ensure the reliability of the installation. For example, the protruding portion 453 has a threaded hole, the intermediate support 10 has a protruding column 12 extending towards the threaded hole, the protruding portion 453 is connected with the protruding column 12 by a first fastener 70, the first guide slot 451 and the second guide slot 452 are both arranged in the middle of the main body portion 454, and the first guide slot 451 and the second guide slot 452 are arranged at intervals. For example, the protruding portion 453 is two, and is arranged on both sides of the main body portion 454. In this way, the contact area between the traction line guide 45 and the intermediate support 10 can be increased, and the traction line guide 45 can be stably fixed to the intermediate support 10.

[0073] In some examples of the present application, as shown in Figure 3 and Figure 4As shown, the synchronous assembly 40 can further include a traction line connector 46 fixedly installed on the adjustment assembly 20. The traction line connector 46 includes a first traction line connector 465, a second traction line connector 466, a third traction line connector 467 and a fourth traction line connector 468. The adjustment assembly 20 includes a first adjustment assembly 25 and a second adjustment assembly 26. The first traction line connector 465 and the second traction line connector 466 are respectively arranged on two sides of the first adjustment assembly 25. The third traction line connector 467 and the fourth traction line connector 468 are respectively arranged on two sides of the second adjustment assembly 26. One end of the second traction line 42 is fixed to the first traction line connector 465. The other end of the second traction line 42 is fixed to the fourth traction line connector 468. One end of the first traction line 41 is fixed to the second traction line connector 466. The other end of the second traction line 42 is fixed to the third traction line connector 467.

[0074] It should be noted that the second traction line connector 466 and the third traction line connector 467 are oppositely arranged. The two ends of the first traction line 41 are respectively connected to the second traction line connector 466 and the third traction line connector 467. The first traction line connector 465 and the fourth traction line connector 468 are oppositely arranged. The second traction line 42 wound on the line rod 43 is adjusted to extend in a direction after passing through two reversing pieces. One end of the second traction line 42 is connected to the first traction line connector 465. The other end of the second traction line 42 is connected to the fourth traction line connector 468. Through the arrangement of the traction line connector 46, the first traction line 41 and the second traction line 42 can be effectively fixed to ensure the structural reliability of the synchronous assembly 40.

[0075] As shown, Figure 9 Each traction line connector 46 can include a first connector 461 and a second connector 463. The first connector 461 is fixed to the adjustment assembly 20, for example, the first connector 461 and the adjustment assembly 20 can be arranged in close contact, connected by welding or the like, and the first connector 461 has a first mounting hole 462 for the second fastener 80 to pass through, so as to connect the traction line connector 46 and the adjustment assembly 20. The second connector 463 has a second mounting hole 464. At least one of the first traction line 41 and the second traction line 42 passes through the second mounting hole 464 to be fixedly installed. The first connector 461 and the second connector 463 are arranged perpendicularly to form an L-shaped structure. In this way, through the arrangement of the first connector 461, the contact area of the traction line connector 46 and the adjustment assembly 20 can be increased, and through the fixed installation of the second fastener 80, the reliability of the assembly can be improved. At the same time, the arrangement of the second connector 463 can facilitate the fixation of the first traction line 41 or the second traction line 42. Through the four traction line connectors 46, the first traction line 41 and the second traction line 42 can be connected into a ring-shaped structure.

[0076] The traction line connector 46 can be made of wear-resistant material. For example, the traction line connector 46 can be made of plastic or metal material to avoid affecting the reliability of the traction line connector 46 due to the repeated friction between the two traction lines and the traction line connector 46 during movement.

[0077] In some embodiments, with reference to Figure 3 and Figure 4 The hub rod 43 can have a first through hole 431 and a second through hole 432 penetrating through the hub rod 43 for the first traction line 41 and the second traction line 42 to pass through, respectively. The first through hole 431 and the second through hole 432 can position the first traction line 41 and the second traction line 42, respectively, to prevent them from being entangled. In addition, the first traction line 41 and the second traction line 42 can be reliably wound around the hub rod 43 to prevent them from coming off, and the installation of the first traction line 41 and the second traction line 42 can be facilitated.

[0078] In addition, the first traction line 41 can form two fixed points at both ends of the first through hole 431, so that when the hub rod 43 rotates, the portion of the first traction line 41 on the left side of the hub rod 43 can be wound around the hub rod 43 in a first direction, and the portion of the first traction line 41 on the right side of the hub rod 43 can be wound around the hub rod 43 in a second direction opposite to the first direction. At this time, the portion of the first traction line 41 on the left side of the hub rod 43 and the portion of the first traction line 41 on the right side of the hub rod 43 can be simultaneously wound around the hub rod 43.

[0079] Similarly, the portion of the first traction line 41 on the left side of the hub rod 43 can be released from the hub rod 43 in the second direction, and the portion of the first traction line 41 on the right side of the hub rod 43 can be released from the hub rod 43 in the first direction. At this time, the portion of the first traction line 41 on the left side of the hub rod 43 and the portion of the first traction line 41 on the right side of the hub rod 43 can be simultaneously released from the hub rod 43.

[0080] It should be noted that the two ends of the portion of the first traction line 41 in the second through hole 432 form two fixed points, which are the first fixed point and the second fixed point, respectively. The portion of the first traction line 41 on the left side of the hub rod 43 is wound around the hub rod 43 or released from the hub rod 43 with the first fixed point as the fixed end, and the portion of the first traction line 41 on the right side of the hub rod 43 is wound around the hub rod 43 or released from the hub rod 43 with the second fixed point as the fixed end.

[0081] It can be understood that the second traction line 42 can form two fixed points at two ends of the second through hole 432, so that when the collecting rod 43 rotates, a section of the second traction line 42 located on the left side of the collecting rod 43 is wound to the collecting rod 43 in a third direction, a section of the second traction line 42 located on the right side of the collecting rod 43 is wound to the collecting rod 43 in a fourth direction, the third direction and the fourth direction are opposite, and at this time, the section of the second traction line 42 located on the left side of the collecting rod 43 and the section of the second traction line 42 located on the right side of the collecting rod 43 can be synchronously wound on the collecting rod 43.

[0082] Similarly, a section of the second traction line 42 located on the left side of the collecting rod 43 is released from the collecting rod 43 in the fourth direction, a section of the second traction line 42 located on the right side of the collecting rod 43 is released from the collecting rod 43 in the third direction, the third direction and the fourth direction are opposite, and at this time, the section of the second traction line 42 located on the left side of the collecting rod 43 and the section of the second traction line 42 located on the right side of the collecting rod 43 can be synchronously released from the collecting rod 43.

[0083] It should be noted here that the two ends of the section of the second traction line 42 located in the second through hole 432 form two fixed points, which are respectively the third fixed point and the fourth fixed point, and the section of the second traction line 42 located on the left side of the collecting rod 43 is wound to the collecting rod 43 or released from the collecting rod 43 with the third fixed point as the fixed end, and the section of the second traction line 42 located on the right side of the collecting rod 43 is wound to the collecting rod 43 or released from the collecting rod 43 with the fourth fixed point as the fixed end.

[0084] According to an embodiment of the present application, in combination Figure 7 The intermediate support 10 is provided with a first matching part 13, and the collecting rod 43 is provided with a second matching part 14, the first matching part 13 and the second matching part 14 match to limit the radial displacement of the collecting rod 43, improve the installation reliability of the synchronous assembly 40, and can ensure the stability of the synchronous movement between the plurality of massage head assemblies 30.

[0085] For example, the outer contour of the first matching part 13 and the second matching part 14 is adapted, the first matching part 13 can be a boss, and the second matching part 14 can be a mounting groove, the collecting rod 43 can be inserted into the mounting groove and can rotate relative to the mounting groove. For example, the collecting rod 43 is cylindrical to ensure the smoothness when the first traction line 41 and the second traction line 42 are wound or separated from the collecting rod 43. Through the setting of the boss, the movement of the collecting rod 43 during rotation can be prevented. The boss can be an annular boss, the mounting groove can be a circular blind hole, and the mounting groove and the collecting rod 43 are matched and assembled to increase the contact area of the mounting groove and the collecting rod 43, facilitate assembly, and facilitate rotation of the collecting rod 43 under the action of force. Of course, the first matching part 13 can also be a mounting groove, and the second matching part 14 can also be a boss, which is not limited here.

[0086] In some examples, such as Figures 11-13 As shown, the synchronization component 40 also includes a fixing cover 47, which covers the cable collection rod 43 and is spaced apart from it. The fixing cover 47 limits the cable collection rod 43, preventing the two traction cables from coming off the rod due to vibration or deformation of the neck massager 100. Simultaneously, the spaced arrangement of the fixing cover 47 and the cable collection rod 43 prevents the fixing cover 47 from obstructing the rotation of the cable collection rod 43, ensuring the stability of the synchronization component 40. The fixing cover 47 may have a through-hole 471 for accommodating the first traction cable 41 and the second traction cable 42, allowing the first traction cable 41 and the second traction cable 42 to pass through the fixing cover 47. The through-hole 471 facilitates the extension of the two traction cables from the fixing cover 47.

[0087] In some embodiments, there may be multiple through holes 471 to facilitate the spacing of the first traction wire 41 and the second traction wire 42, preventing the first traction wire 41 and the second traction wire 42 from tangling. In other examples, such as Figure 11 As shown, there can be one through hole 471, which can be a through hole extending through the fixing cover 47. The edge of the through hole 471 has a spaced protrusion 472 to separate the first traction wire 41 and the second traction wire 42. By providing the spaced protrusion 472, the first traction wire 41 and the second traction wire 42 can be separated to prevent the first traction wire 41 and the second traction wire 42 from shifting due to the vibration or deformation of the neck massager 100.

[0088] For example, the wire through hole 471 has spacer protrusions 472 at both ends and on both sides to further ensure the reliability of the spacing between the first traction wire 41 and the second traction wire 42. The wire through holes 471, spaced apart by the spacer protrusions 472, can be spaced out as follows: Figure 11 The first and second guide spaces are arranged vertically. The first guide space accommodates a portion of the first traction wire 41. The first guide space is, for example... Figure 11 The vertical dimension is 1mm larger than the diameter of the first traction wire 41. The second wire passage space accommodates a portion of the second traction wire 42. The second wire passage space is, for example... Figure 11 The vertical dimension of the first traction wire 41 is 1mm larger than the diameter of the second traction wire 42. This avoids friction caused by the two traction wires being too close to the fixing cover 47, and also effectively prevents the first traction wire 41 and the second traction wire 42 from shifting to each other due to the vibration or deformation of the neck massager 100.

[0089] Combination Figures 11-13The fixed cover 47 can include a main cover body 473 and at least one mounting protrusion 474. The main cover body 473 can be attached to the first fitting part 13. The mounting protrusion 474 protrudes from the main cover body 473. The intermediate support 10 has an assembly protrusion 18 protruding towards the mounting protrusion 474. The assembly protrusion 18 and the mounting protrusion 474 are connected by the third fastener 90. In this way, the movement of the wire collecting rod 43 along the axial direction of the wire collecting rod 43 can be effectively prevented when the wire collecting rod 43 rotates, and the second fitting part 14 is separated. The reliability of the synchronous assembly 40 is ensured.

[0090] In some embodiments, as shown in Figures 3-6 The adjustment assembly 20 can further include a sliding member 22. One end of the sliding member 22 is connected to the damping member 21, and the other end of the sliding member 22 is connected to the massage head assembly 30. At least a part of the sliding member 22 is arranged in the accommodating space 15. For example, the sliding member 22 can be a sliding block or a roller that can slide with the intermediate support 10. The roller has small sliding friction with the intermediate support 10, smooth sliding, and good adaptability to the deformation of the intermediate support 10. The traction line connector 46 can be connected to the sliding member 22 to ensure the reliability of the connection. Through the arrangement of the sliding member 22, the movement of the adjustment assembly 20 can be facilitated.

[0091] In some examples, as shown in Figure 5 The sliding member 22 and one of the damping members 21 are provided with a plug-in groove 24, and the other is provided with a plug-in protrusion 23. For example, the sliding member 22 has the plug-in groove 24, and the damping member 21 has the plug-in protrusion 23, so that the sliding member 22 and the damping member 21 are plug-in fitted. In this way, on the one hand, the installation and positioning of the sliding member 22 and the damping member 21 can be facilitated, the two massage head assemblies 30 can be positioned, and the assembly efficiency can be improved. On the other hand, the assembly reliability of the sliding member 22 and the damping member 21 can be improved.

[0092] As shown in Figure 5 The damping member 21 can have a moving part 211. The moving part 211 is in interference connection with the intermediate support 10. One end of the moving part 211 away from the human neck is hemispherical. The other end of the moving part 211 towards the human neck is attached to the sliding member 22. It should be noted that when the moving part 211 is not under force, the one end of the moving part 211 away from the human neck is hemispherical. Of course, in other examples, the shape of the moving part 211 can also be square or other shapes, which are not limited here.

[0093] It should be noted that in combination with Figure 5The interference fit between the damping member 21 and the inner wall of the intermediate support 10 is achieved by the compression deformation of the damping member 21, and the friction between the damping member 21 and the inner wall of the intermediate support 10 can be determined by the compression amount of the damping member 21, that is, the adjustment of the strength of the damping feeling of the massage head assembly 30 can be determined by the compression amount of the damping member 21, and the compression amount can be determined by the contact area S and the interference contact height H of the moving part 211 and the intermediate support 10, so the strength of the damping feeling can be adjusted by adjusting the cross-sectional shape of the moving part 211 and the interference contact height. Figure 5 The damping member 21 shown is in a state of not being compressed and deformed, and is only schematically illustrated.

[0094] As shown in Figure 5 and Figure 6 , the sliding member 22 can have a wire passing hole 221 passing through the sliding member 22, and the second traction line 42 is threaded through the wire passing hole 221. The damping member 21 can avoid the wire passing hole 221, or the wire passing hole 221 can be provided through the damping member 21, and by providing the wire passing hole 221, the second traction line 42 can be conveniently limited.

[0095] In some embodiments, as shown in Figure 2 , the intermediate support 10 includes a first support 16 and a second support 17, the first support 16 is located on the side of the second support 17 away from the human neck, the damping member 21 is interference fitted with the inner wall of the first support 16, and the first support 16 and the second support 17 together define a containing space 15. For example, the synchronous assembly 40 can be provided in the containing space 15. The first support 16 can be an elastic member, and the second support 17 can be a silica gel member to facilitate the deformation of the intermediate support 10 following the twisting or turning of the human body, so that the massage head assembly 30 can be effectively attached to the human neck, and at the same time, when the adjustment assembly 20 moves relative to the first support 16, it is not affected by slight interference forces from the outside,

[0096] The movement principle of the plurality of massage head assemblies 30 of the neck massager 100 according to the embodiments of the present application will be described below with reference to Figure 3 and Figure 4 The following description is only schematically described and does not represent a specific limitation on the present application. For example, the massage head assembly 30 can be two, which are a first massage head assembly 31 and a second massage head assembly 32. The two massage head assemblies 30 can be synchronously folded or synchronously separated.

[0097] The first traction line 41 can be wound on the collecting rod 43 in a clockwise direction (for example, in the direction of the arrow shown in Figure 3 , and both ends are reserved a certain length. The second traction line 42 can be wound on the collecting rod 43 in a counterclockwise direction (for example, Figure 4The first traction line 41 is threaded through the first through hole 431 so that the first traction line 41 can form two fixed points at the two ends of the first through hole 431 to enable the two ends of the first traction line 41 to be synchronously wound in or out of the collecting rod 43. The second traction line 42 is threaded through the second through hole 432 so that the second traction line 42 can form two fixed points at the two ends of the first through hole 431 to enable the two ends of the second traction line 42 to be synchronously wound in or out of the collecting rod 43. The left end of the first traction line 41 is fixed to the third traction line connector 467, and the right end is fixed to the fourth traction line connector 468. The two ends of the second traction line 42 pass through the traction line guide 45 and the wire hole 221, respectively. After the two ends of the second traction line 42 pass around the two reversing pieces 440, the left end of the second traction line 42 is fixed to the first traction line connector 465, and the right end is fixed to the fourth traction line connector 468.

[0098] When the first massage head assembly 31 moves in a direction away from the second massage head assembly 32, the second massage head assembly 32 moves in a direction away from the first massage head assembly 31; when the first massage head assembly 31 moves in a direction toward the second massage head assembly 32, the second massage head assembly 32 moves in a direction toward the first massage head assembly 31. It should be noted that the user can adjust any massage head assembly 30 to achieve synchronous movement of multiple massage head assemblies 30.

[0099] The principle of movement of the massage head assembly 30 of the present application will be further described below with the user adjusting the first massage head assembly 31 on the left side as an example. The first massage head assembly 31 is connected to the first adjustment assembly 25, and the second massage head assembly 32 on the right side is connected to the second adjustment assembly 26.

[0100] As shown in Figure 3 When the user applies a leftward force to the first massage head assembly 31, the first massage head assembly 31 can move to the left, and the second massage head assembly 32 can synchronously move to the right, so that the two massage heads are separated.

[0101] Specifically, the drag force applied by the user to the left massage head assembly 30 can be transmitted to the sliding piece 22 of the first adjustment assembly 25, which can pull the first traction line 41 so that a tension can be generated inside the first traction line 41, which can be transmitted to the collecting rod 43, thereby driving the collecting rod 43 to rotate clockwise (for example, along the arrow direction shown in the figure). Figure 3(The arrow shown rotates clockwise), so that the part of the first traction line 41 wrapped around the hub rod 43 can gradually unwrap and generate torque. The torque can be transmitted to the second traction line 42, causing the second traction line 42 to wrap around the hub rod 43. The length of the free ends (i.e., the parts not wrapped around the hub rod 43) of the left and right ends of the second traction line 42 becomes shorter. Due to the shortening of the length of the free end on the right side of the second traction line 42, tension is generated. The sliding member 22 can have a wire hole 221 that passes through the sliding member 22. After the second traction line 42 passes through the wire hole 221, it can change direction through the second reversing member 442 using the principle of a fixed pulley. The right end of the second traction line 42 after changing direction is connected to the right end of the first traction line 41 through the sliding member 22. This allows for motion transmission between the first traction wire 41 and the second traction wire 42, applying force to the slider 22 of the second adjustment assembly 26 on the right. For example, the free end of the second traction wire 42 on the right can apply a dragging force to the slider 22, causing the second massage head assembly 32 to move to the right. This achieves the separation of the second massage head assembly 32 from the first massage head assembly 31, and the synchronous separation of the first massage head assembly 31 and the second massage head assembly 32. Because the first traction wire 41 is wound out and the second traction wire 42 is wound in, both traction wires are always taut, preventing any slack wire from interfering with other components.

[0102] like Figure 4 As shown, the user applies a rightward force to the first massage head assembly 31, so that the first massage head assembly 31 can move to the right, and the second massage head assembly 32 can move to the left simultaneously, so that the two massage head assemblies 30 close together.

[0103] The dragging force applied by the user to the first massage head assembly 31 on the left side is transmitted to the slider 22 of the first adjustment assembly 25. The slider 22 can pull the second traction cable 42, generating tension inside the second traction cable 42. This tension is further transmitted to the cable hub 43, causing the cable hub 43 to rotate (e.g., along the...). Figure 4When the first adjusting assembly 21 is rotated clockwise (i.e. the arrow direction shown rotates counterclockwise), the portion of the second traction line 42 wound on the collecting rod 43 gradually unwinds, and a torque is generated, which is transmitted to the first traction line 41 to make the first traction line 41 further wound on the collecting rod 43, and the free ends of the first traction line 41 on both sides (i.e. the portion not wound on the collecting rod 43) become shorter, and a tension is generated due to the shortening of the free end of the first traction line 41 on the right side, the sliding member 22 can have a wire passing hole 221 passing through the sliding member 22, and the second traction line 42 can pass through the wire passing hole 221, and the second traction line 42 can change direction by the second reversing member 442 by using the pulley principle, and the right end of the second traction line 42 after changing direction is connected to the right end of the first traction line 41 through the sliding member 22. Thus, the motion transmission between the first traction line 41 and the second traction line 42 can be achieved to exert a leftward force on the sliding member 22 of the second adjusting assembly 26 on the right side, for example, the free end of the first traction line 41 on the right side can exert a leftward pulling force on the sliding member 22 to move the second massage head assembly 32 to the left, so that the second massage head assembly 32 and the first massage head assembly 31 are close to each other, so that the left and right massage head assemblies 30 are synchronized to close, and because the second traction line 42 unwinds and the first traction line 41 winds, the two traction lines are always in a taut state, and slackening of a certain line to interfere with other parts can be avoided.

[0104] In some examples, the right end of the second traction line 42 wound on the collecting rod 43 can extend from the side of the collecting rod 43 facing the neck of the human body, and the left end of the second traction line 42 can extend from the side of the collecting rod 43 away from the neck of the human body. The left end of the first traction line 41 wound on the collecting rod 43 can extend from the side of the collecting rod 43 facing the neck of the human body, and the right end of the first traction line 41 can extend from the side of the collecting rod 43 away from the neck of the human body. Of course, in other examples, the first traction line 41 and the second traction line 42 can also have opposite winding directions.

[0105] Other components of the neck massager 100 according to the embodiments of the present application, such as the clamping arm 50 and the electrical connector 60, and the operation are known to those skilled in the art, and will not be described in detail here.
