Description

Technical Field

[0001] The present invention relates to the technical field of massagers, and in particular to a massage comb. Background Art

[0002] Massage and health care is a way of keeping in good health. Nowadays, people's fast-paced life makes the body often in a state of fatigue, and long-term fatigue work will affect people's health. Massage can dredge the meridians, promote blood circulation, and make people relax.

[0003] Traditional combs, as common hair-combing products in people's daily life, usually only have the function of combing hair. There are also massage combs on the market for massaging the head. Such massage combs only have the functions of combing hair and massaging the head, and do not have other functions. Moreover, the massage heads of such massage combs rotate circumferentially, resulting in hair entanglement when the user has long hair during the massage process, and the user experience is poor. Summary of the Invention

[0004] In view of this, the present invention provides a massage comb with rich functions and a reduced risk of hair entanglement.

[0005] A massage comb, comprising:

[0006] A housing, including a comb handle and a comb head connected to the comb handle, and an installation part is provided on the comb head;

[0007] A turntable, rotatably installed on the comb head;

[0008] A plurality of first comb tooth parts, movably installed on the comb head and connected to the turntable;

[0009] A driving mechanism, installed in the housing and connected to the turntable to drive the turntable to rotate, so as to drive one ends of the plurality of first comb tooth parts away from the turntable to close inward or open outward;

[0010] A function module, installed on the installation part, and the plurality of first comb tooth parts surround the outer periphery of the function module.

[0011] In some embodiments, the installation part is an installation hole penetrating the comb head, and the function module is detachably installed in the installation hole.

[0012] In some embodiments, the plurality of first comb tooth parts are sequentially connected end to end in the rotation direction of the turntable to form a ring, and adjacent two first comb tooth parts are movably connected.

[0013] In some embodiments, the first comb tooth part includes a driving comb tooth part movably installed on the comb head and a driven comb tooth part movably installed on the comb head. A plurality of the driving comb tooth parts and a plurality of the driven comb tooth parts are alternately distributed along the rotation direction of the turntable and are sequentially movably connected. The driving comb tooth part is connected to the turntable so that the driving comb tooth part can swing relative to the comb head under the drive of the turntable and drive the driven comb tooth part to swing relative to the comb head.

[0014] In some embodiments, both the driving comb tooth part and the driven comb tooth part include a first base rotatably installed on the comb head and a first comb tooth extending from the first base away from the turntable to the outside of the comb head. Adjacent first bases are movably connected, and the first base of the driving comb tooth part is connected to the turntable to be driven by it.

[0015] In some embodiments, two adjacent first bases are movably matched through a groove and a connecting piece located in the groove. The connecting piece is fixed relative to the groove in the rotation direction of the first base so that the driving comb tooth part can drive the driven comb tooth part to swing through the cooperation of the connecting piece and the groove.

[0016] In some embodiments, the first base of the driving comb tooth part is provided with a first convex column, and the turntable is provided with a first cam structure. The first convex column extends away from the first comb tooth and is movably matched with the first cam structure.

[0017] In some embodiments, the massage comb further includes a plurality of second comb tooth parts movably installed on the comb head. The plurality of second comb tooth parts are located inside the first comb tooth part and are spaced apart along the rotation direction of the turntable. The plurality of second comb tooth parts are respectively connected to the turntable so that one ends of the plurality of second comb tooth parts away from the turntable can be retracted inward or opened outward when the turntable rotates.

[0018] In some embodiments, the plurality of second comb tooth parts correspond to the plurality of driving comb tooth parts in the radial direction of the turntable, and the second comb tooth part and the corresponding driving comb tooth part swing in the same direction synchronously under the drive of the turntable.

[0019] In some embodiments, the second comb tooth part includes a second base rotatably installed on the comb head and a second comb tooth extending from the second base away from the turntable to the outside of the comb head. The second base is provided with a second convex column, and the turntable is provided with a second cam structure. The second convex column extends away from the second comb tooth and is movably matched with the second cam structure.

[0020] In the massage comb provided by the present invention, when the driving mechanism drives the rotating disk to rotate, the first comb teeth can swing relative to the comb head under the action of the rotating disk, so that the end of the plurality of first comb teeth away from the rotating disk can be retracted inward or opened outward, imitating the action of fingers grasping and pinching, thereby forming a massage effect, and a functional module is installed on the comb head, enriching the functions of the massage comb. Since the end of the first comb teeth away from the rotating disk swings inward or outward relative to the comb head, compared with the method of rotating around the comb head, the risk of the massage comb wrapping the hair around the first comb teeth during use can be reduced, so that the massage comb is not only suitable for users with short hair, but also for users with long hair, and has a wider range of applications.

Detailed implementation manners

[0033] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom...) in the embodiments of the present invention are only used to explain the relative position relationship between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly.

[0035] It should also be noted that when an element is referred to as "fixed to" or "disposed on" another element, the element can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0036] Please refer to Figures 1 to 3, a massage comb 10 provided by an embodiment of the present invention includes a housing 12, a plurality of first comb teeth portions 14, a turntable 16, and a driving mechanism 18. The plurality of first comb teeth portions 14 are movably installed on the housing 12. The plurality of first comb teeth portions 14 are connected to the turntable 16 and driven by it. The turntable 16 is rotatably installed in the housing 12. The driving mechanism 18 is installed in the housing 12 and connected to the turntable 16 to drive the turntable 16 to rotate relative to the housing 12, thereby driving the ends of the plurality of first comb teeth portions 14 away from the turntable 16 to converge inward or diverge outward. After the driving mechanism 18 drives the turntable 16 to rotate, the turntable 16 can drive the plurality of first comb teeth portions 14 to swing, so that the ends of the plurality of first comb teeth portions 14 away from the turntable 16 converge inward or diverge outward, imitating the finger pinching action to form a massage effect. This enables the massage comb 10 not only to comb hair with the plurality of first comb teeth portions 14, but also to form a massage effect with the first comb teeth portions 14, enriching the functions of the massage comb 10. At the same time, since the first comb teeth portions 14 swing relative to the housing 12, compared with the circumferential rotation method, the risk of the massage comb 10 winding hair around the first comb teeth portions 14 can be reduced, making the massage comb 10 suitable for both long-haired and short-haired users, with a wider range of applications.

[0037] The housing 12 includes a comb handle 20 for the user to hold and a comb head 22 fixed to one end of the comb handle 20. The turntable 16 is movably installed in the comb head 22. The first comb teeth portions 14 are movably installed in the comb head 22, and the ends of the first comb teeth portions 14 away from the turntable 16 extend out of the comb head 22 for contact with the user's head.

[0038] The comb head 22 includes a housing 24 and a mounting structure 26. The housing 24 is fixed to one end of the comb handle 20, and the axial direction of the housing 24 is perpendicular to the axial direction of the comb handle 20. The mounting structure 26 is located inside the housing 24 and is fixed relative to the housing 24. The turntable 16 is movably installed inside the housing 24 and is located between the mounting structure 26 and the housing 24. The plurality of first comb teeth portions 14 are movably installed on the mounting structure 26. The driving mechanism 18 drives the turntable 16 to rotate inside the housing 24 and pushes the plurality of first comb teeth portions 14 to swing relative to the mounting structure 26.

[0039] The mounting structure 26 includes a first comb teeth cover 28 and a second comb teeth cover 30 connected to one side of the first comb teeth cover 28. The turntable 16 is located on the side of the first comb teeth cover 28 away from the second comb teeth cover 30. A part of the first comb teeth portion 14 is clamped between the first comb teeth cover 28 and the second comb teeth cover 30 and can rotate relative to the first comb teeth cover 28 and the second comb teeth cover 30, thereby movably installing the plurality of first comb teeth portions 14 on the mounting structure 26.

[0040] The comb head 22 further includes a protective cover 32, which is located on a side of the second comb tooth cover 30 away from the first comb tooth cover 28 and is sealed to the housing 24. The mounting structure 26 is located between the housing 24 and the protective cover 32, and one end of the plurality of first comb tooth portions 14 away from the rotating disk 16 extends out of the protective cover 32. The protective cover 32 can prevent the mounting structure 26 from being exposed, making the massage comb 10 more aesthetically pleasing, and also enhances the sealing performance of the massage comb 10, preventing hair from being rolled into the inside of the massage comb 10, and improving the safety of the massage comb 10.

[0041] The specific method of achieving sealing between the protective cover 32 and the housing 24 is not limited. For example, it can be by providing a sealing ring between the two, or by providing a sealing glue between the two.

[0042] The specific material of the protective cover 32 is not limited. In the present embodiment, the protective cover 32 is a silicone cover.

[0043] like Figure 1 As shown, in some embodiments, the massage comb 10 further includes a functional module, a mounting portion is provided on the comb head 22, the functional module is mounted on the mounting portion, and a plurality of first comb teeth 14 surround the periphery of the functional module. The functional module includes but is not limited to one of an essential oil module 110, a hot compress module 112 or an atomization module 114, so that the massage comb 10 not only has the functions of combing hair and massaging, but also has the corresponding functions of the functional module, further enriching the functions of the massage comb 10.

[0044] In this embodiment, the mounting portion is a mounting hole 116 that passes through the combing head 22, and the functional module is detachably mounted in the mounting hole 116. Mounting the functional module in the mounting hole 116 can reduce the abruptness of the functional module and also facilitate users to replace the functional module by themselves.

[0045] The specific manner in which the functional module and the comb head 22 are detachably connected is not limited, for example, it can be through a snap-fit ​​manner or an interference fit manner.

[0046] The specific number of the functional modules is not limited, and can be one or more. When there are more than one functional modules, the user can select a corresponding functional module from the multiple functional modules and install it in the installation hole 116 as needed.

[0047] See also Figure 3 and Figure 7, in one embodiment, a plurality of first comb teeth portions 14 are sequentially connected end to end along the rotation direction of the turntable 16 to form a ring, and two adjacent first comb teeth portions 14 are movably connected. So that under the action of the turntable 16, the plurality of first comb teeth portions 14 can not only swing relative to the comb head 22, but also enable adjacent first comb teeth portions 14 to move relative to each other, so that the ends of the plurality of first comb teeth portions 14 away from the turntable 16 can simultaneously open outwards or close inwards. The plurality of first comb teeth portions 14 are connected end to end to form a ring. Compared with the arrangement in which the plurality of first comb teeth portions 14 are arranged at intervals, the space on the housing 12 is fully utilized to set a larger number of first comb teeth portions 14, increasing the contact area between the massage comb 10 and the user's head, increasing the massage area of the massage comb 10, and improving the user experience.

[0048] In another embodiment, a plurality of first comb teeth portions are arranged at intervals along the rotation direction of the turntable.

[0049] In some embodiments, a first cam structure 34 is provided on the side of the turntable 16 close to the first comb teeth portion 14, and a first convex column 36 is provided on the first comb teeth portion 14. The plurality of first comb teeth portions 14 are respectively movably matched with the first cam structure 34 through the corresponding first convex columns 36. When the turntable 16 rotates under the drive of the drive mechanism 18, the first cam structure 34 rotates together with the turntable 16. During the rotation process, the first cam structure 34 drives the plurality of first comb teeth portions 14 to swing through the first convex columns 36, so that the ends of the plurality of first comb teeth portions 14 away from the turntable 16 close inwards or open outwards.

[0050] The first cam structure 34 can be one or more cams installed on the turntable 16, or a cam groove provided on the turntable 16.

[0051] In this embodiment, the first cam structure 34 is a first cam groove, a first convex column 36 is provided on the first comb teeth portion 14, and the end of the first convex column 36 away from the first comb teeth portion 14 is movably inserted into the first cam groove. When the turntable 16 rotates, the first cam groove can rotate relative to the first convex column 36, and the groove wall of the first cam groove can push the first convex column 36 to swing, thereby driving the first comb teeth portion 14 to swing.

[0052] The first comb tooth part 14 includes a driving comb tooth part 38 and a driven comb tooth part 40. A plurality of driving comb tooth parts 38 and a plurality of driven comb tooth parts 40 are movably installed on the comb head 22. The plurality of driving comb tooth parts 38 and the plurality of driven comb tooth parts 40 are alternately distributed along the rotation direction of the turntable 16 and are movably connected to form a ring shape. The first convex column 36 is arranged on the driving comb tooth part 38. That is, the driving comb tooth part 38 is movably matched with the turntable 16 through the first convex column 36 and the first cam groove. When the turntable 16 rotates, the driving comb tooth part 38 can swing relative to the comb head 22 under the action of the first cam groove and the first convex column 36, and drive the driven comb tooth part 40 to swing relative to the comb head 22, so that the ends of the driving comb tooth part 38 and the driven comb tooth part 40 far from the turntable 16 synchronously move inwards or outwards.

[0053] Both the driving comb tooth part 38 and the driven comb tooth part 40 include a first base 42 and a first comb tooth 44 connected to the first base 42. The first base 42 of the driving comb tooth part 38 is movably connected to the first base 42 of the driven comb tooth part 40. The first base 42 is rotatably installed on the comb head 22. The first comb tooth 44 extends from the first base 42 in the direction away from the turntable 16 to the outside of the comb head 22. The first convex column 36 is arranged on the first base 42 of the driving comb tooth part 38 and extends in the direction away from the first comb tooth 44. Specifically, the first base 42 can be movably clamped between the first comb tooth cover 28 and the second comb tooth cover 30. One end of the first convex column 36 far from the first comb tooth 44 passes through the first comb tooth cover 28 and can be movably inserted into the first cam groove. One end of the first comb tooth 44 far from the first convex column 36 passes through the second comb tooth cover 30 and the protective cover 32 and extends out of the protective cover 32. When the driving mechanism 18 drives the turntable 16 to rotate, the turntable 16 first pushes the first convex column 36 to swing through the first cam groove. The first convex column 36 then drives the first base 42 connected thereto to move. The first base 42 drives the first base 42 of the driven comb tooth part 40 connected thereto to rotate. The first bases 42 of the driving comb tooth part 38 and the driven comb tooth part 40 then drive the corresponding first comb teeth 44 to move, and finally the ends of the first comb teeth 44 far from the first bases 42 move inwards or outwards.

[0054] The specific number of the first comb teeth 44 on each first base 42 is not limited. It can be one or multiple. In this embodiment, a plurality of first comb teeth 44 arranged at intervals are provided on each first base 42.

[0055] The first convex column 36, the first base 42 of the driving comb tooth part 38 and the first comb tooth 44 of the driving comb tooth part 38 can be integrally formed or assembled in a split manner. In this embodiment, it is preferably integrally formed, which can not only ensure the connection strength but also save the assembly process. Similarly, the first base 42 and the first comb tooth 44 of the driven comb tooth part 40 can also be integrally formed or assembled in a split manner.

[0056] Please refer to Figures 8 to 10 On the comb head 22, there is a support base 46 that cooperates with the first base 42. A support hole 48 is provided inside the support base 46. The two ends of the first base 42 are respectively rotatably received in the support holes 48 of the corresponding support bases 46, so that the first base 42 of the active comb tooth part 38 and the driven comb tooth part 40 can rotate relative to the comb head 22 around the central axis of the support hole 48 under the action of the first convex post 36 and the first cam groove. Specifically, in this embodiment, both the first base 42 and the support hole 48 are cylindrical. Therefore, after the end of the first base 42 is inserted into the support hole 48, the effect of rotational fit can be achieved.

[0057] There are a plurality of first accommodation grooves 50 for accommodating the first base 42 between the first comb tooth cover 28 and the second comb tooth cover 30, and the plurality of first accommodation grooves 50 are spaced from each other. The support base 46 is located between two adjacent first accommodation grooves 50, and the support hole 48 communicates with two adjacent first accommodation grooves 50. The first comb tooth cover 28 is provided with a first avoidance groove 52 that communicates with the first accommodation groove 50 to avoid the first convex post 36, and the second comb tooth cover 30 is provided with a second avoidance groove 54 that communicates with the first accommodation groove 50 to avoid the first comb teeth 44. The middle part of the first base 42 is received in the first accommodation groove 50, and the two ends are respectively rotatably received in the support holes 48 of two adjacent support bases 46. One end of the first convex post 36 passes through the first avoidance groove 52 and then is inserted into the first cam groove, and the first comb teeth pass through the second avoidance groove 54 and thus extend out of the comb head 22.

[0058] Two adjacent first bases 42 are movably fitted through a connecting member 56 and a groove 58, that is, the first base 42 of the active comb tooth part 38 and the first base 42 of the adjacent driven comb tooth part 40 achieve the effect of movable connection through the cooperation of the connecting member 56 and the groove. In the circumferential direction of the rotation direction of the first base 42, that is, the circumferential direction of the support hole 48, the connecting member 56 is fixed relative to the groove 58, so that the connecting member 56 cannot rotate in the groove 58 in this direction. Therefore, when the first base 42 drives the connecting member 56 to rotate, the connecting member 56 can drive the adjacent first base 42 provided with the groove 58 that cooperates with it to rotate together, achieving the effect that the active comb tooth part 38 drives the driven comb tooth part 40 to swing.

[0059] The specific cooperation method between the connecting member 56 and the groove 58 is not limited, as long as it is relatively fixed in the rotation direction of the first base 42 and is movably fitted in other directions, such as the axial direction of the first base 42. In this embodiment, the connecting member 56 and the first base 42 are cylindrical, and there is an angle, such as being perpendicular to each other, between the axial direction of the connecting member 56 and the axial direction of the corresponding first base 42 to achieve the effect of relative fixation.

[0060] In other embodiments, a limiting surface, such as a flat surface, is provided between the connecting member and the groove to prevent the connecting member from rotating relative to the groove in the rotation direction of the first base.

[0061] As Figure 5 shown, in this embodiment, grooves 58 are respectively provided at both ends of the first base 42 of the active comb teeth portion 38, and connecting members 56 are respectively provided at both ends of the first base 42 of the driven comb teeth portion 40. The two grooves 58 of the active comb teeth portion 38 are respectively in movable cooperation with the corresponding connecting members 56 of two adjacent driven comb teeth portions 40.

[0062] In another embodiment, connecting members are respectively provided at both ends of the first base of the active comb teeth portion, grooves are respectively provided at both ends of the first base of the driven comb teeth portion, and the two connecting members of the active comb teeth portion are respectively in movable cooperation with the corresponding grooves of two adjacent driven comb teeth portions.

[0063] In yet another embodiment, both a connecting member and a groove are respectively provided at both ends of the first base of the active comb teeth portion, and both a connecting member and a groove are also respectively provided at both ends of the first base of the driven comb teeth portion. The connecting member of the active comb teeth portion is in movable cooperation with the groove of the adjacent driven comb teeth portion, and the groove of the active comb teeth portion is in movable cooperation with the connecting member of the adjacent driven comb teeth portion.

[0064] Please refer to Figure 3 、 Figure 4 and Figure 6 , in some embodiments, the massage comb 10 further includes a plurality of second comb teeth portions 60 movably mounted on the comb head 22. The plurality of second comb teeth portions 60 are arranged at intervals along the rotation direction of the turntable 16. The second comb teeth portions 60 are located inside the first comb teeth portion 14 and are spaced apart from the first comb teeth portion 14. The plurality of second comb teeth portions 60 are respectively movably connected to the turntable 16 and driven by it, so that the ends of the plurality of second comb teeth portions 60 away from the turntable 16 can be driven by the turntable 16 to close inward or open outward. The plurality of first comb teeth portions 14 are connected end to end to form a ring. The second comb teeth portions 60 are located inside the first comb teeth portion 14, so that two layers of comb teeth portions are formed in the radial direction. Both the first comb teeth portion 14 and the second comb teeth portion 60 can form a massage effect, further increasing the massage area of the massage comb 10.

[0065] The specific number of layers of the comb teeth portion in the radial direction is not limited. For example, in addition to the two layers in this embodiment, there may also be only one layer, or multiple layers of three layers or more.

[0066] The turntable 16 is provided with a second cam structure 62, and the second comb-tooth portion 60 is provided with a second convex column 64 that movably cooperates with the second cam structure 62. The plurality of second comb-tooth portions 60 movably cooperate with the second cam structure 62 through the corresponding second convex columns 64, so that the ends of the plurality of second comb-tooth portions 60 away from the turntable 16 can be retracted inwards or opened outwards when the turntable 16 rotates. When the driving mechanism 18 drives the turntable 16 to rotate, the second cam structure 62 rotates with the turntable 16, and drives the plurality of second comb-tooth portions 60 to swing relative to the comb head 22, so that the ends of the second comb-tooth portions 60 away from the turntable 16 are retracted inwards or opened outwards, so as to imitate the pinching action of fingers, thereby forming a massage effect.

[0067] The second cam structure 62 may be one or more cams installed on the turntable 16 , or may be a cam groove provided on the turntable 16 .

[0068] In this embodiment, the second cam structure 62 is a second cam groove provided on the side of the rotating disk 16 close to the second comb tooth portion 60, and a second protrusion 64 is provided on the second comb tooth portion 60, and an end of the second protrusion 64 away from the second comb tooth portion 60 can be movably inserted into the second cam groove. When the rotating disk 16 rotates, the second cam groove rotates relative to the second protrusion 64, and the groove wall of the second cam groove can push the second protrusion 64 to swing, thereby driving the second comb tooth portion 60 to swing.

[0069] The second comb tooth portion 60 includes a second base 66 and second comb teeth 68 connected to the second base 66. The second base 66 is movably mounted on the mounting structure 26. The second comb teeth 68 extend from the second base 66 to the outside of the comb head 22 in a direction away from the rotary disk 16. The second protrusion 64 is provided on the second base 66 and extends in a direction away from the second comb teeth 68. When the rotary disk 16 rotates, the second protrusion 64 is pushed to swing through the second cam groove. The second protrusion 64 drives the second base 66 and the second comb teeth 68 to move relative to the mounting structure 26, and finally causes the end of the second comb teeth 68 away from the second base 66 to retract inward or open outward.

[0070] The specific number of the second comb teeth 68 on each second base 66 is not limited, and may be one or more. In the present embodiment, each second base 66 is provided with a plurality of second comb teeth 68 arranged at intervals.

[0071] The second protruding column 64, the second base 66 and the second comb teeth 68 can be integrally formed or assembled separately. In the present embodiment, they are preferably integrally formed, which can ensure the connection strength and save the assembly process.

[0072] like Figure 9 and Figure 10As shown, between the first comb-tooth cover 28 and the second comb-tooth cover 30, there are a plurality of second accommodation grooves 70 for accommodating the second base 66, and the plurality of second accommodation grooves 70 are spaced from each other. At both ends of the second accommodation groove 70, depressions are formed to form shaft holes 72. At both ends of the second base 66, rotating shafts 74 are respectively provided, and the rotating shafts 74 are inserted into the corresponding shaft holes 72, so as to rotatably mount the second comb-tooth part 60 on the comb head 22.

[0073] The first comb-tooth cover 28 is provided with a third avoidance groove 76 communicating with the second accommodation groove 70, and the second comb-tooth cover 30 is provided with a fourth avoidance groove 78 communicating with the second accommodation groove 70. One end of the second convex post 64 away from the second base 66 passes through the third avoidance groove 76 and is movably inserted into the second cam groove, and one end of the second comb tooth 68 away from the second base 66 passes through the fourth avoidance groove 78 and extends out of the comb head 22.

[0074] As Figure 3 and Figure 6 shown, in some embodiments, the plurality of second comb-tooth parts 60 and the plurality of active comb-tooth parts 38 correspond to each other in the radial direction of the turntable 16, that is, in the direction perpendicular to the rotation axis of the turntable 16, and the second comb-tooth part 60 and the corresponding active comb-tooth part 38 swing synchronously in the same direction under the drive of the turntable 16, so as to avoid interference between the second comb-tooth part 60 and the first comb-tooth part 14 during the swinging process.

[0075] Both the first cam groove and the second cam groove are annular and wavy, and both the first cam groove and the second cam groove include a plurality of alternately distributed wave crests 80 and wave troughs 82.

[0076] The first cam groove and the second cam groove have the same shape, and their wave crests 80 and wave troughs 82 respectively correspond to each other in the radial direction. That is, in the radial direction of the first cam groove, the plurality of wave crests 80 of the first cam groove and the plurality of wave crests 80 of the second cam groove respectively correspond to each other, the plurality of wave troughs 82 of the first cam groove and the plurality of wave troughs 82 of the second cam groove respectively correspond to each other, the plurality of second comb-tooth parts 60 and the plurality of active comb-tooth parts 38 respectively correspond to each other, and the first convex post 36 and the second convex post 64 are spaced and parallel, so that when the turntable 16 rotates, it can drive the active comb-tooth part 38 and the second comb-tooth part to swing in the same direction synchronously, avoiding the problem of interference due to different swinging directions of the two.

[0077] In some embodiments, the number of wave crests 80 of the first cam groove is the same as the number of wave troughs 82, the number of wave crests 80 of the second cam groove is the same as the number of wave troughs 82, and the number of wave crests 80 of the first cam groove is the same as the number of wave crests 80 of the second cam groove. The number of active comb-tooth parts 38 and the number of second comb-tooth parts 60 are both the same as the number of wave crests 80 of the first cam groove.

[0078] The center of the first cam groove (i.e., the position where the radial distances to the two opposite groove walls of the first cam groove are equal) has a sine relationship with the inclination angle of the first convex post 36 in the radial distance from the central axis of the turntable 16. The center of the second cam groove has a sine relationship with the inclination angle of the second convex post 64 in the radial distance from the central axis of the turntable 16. Here, taking the first cam groove as an example, the radial distance L between the center of the first cam groove and the central axis of the turntable 16 is L = a×sinθ + b, where a is the distance between the central axis of the first base 42 and the end of the first convex post 36 far from the first base 42, θ is the inclination angle of the first convex post 36 relative to the vertical direction, and b is the radial distance between the central axis of the first base 42 and the central axis of the turntable 16.

[0079] Please refer to Figure 2 、 Figure 3 and Figure 11 , in some embodiments, the drive mechanism 18 includes a motor 84 and a gear set 86 that is drivingly connected to the motor 84. The motor 84 is located within the comb handle 20 of the housing 12, and the gear set 86 is connected to the turntable 16 to drive the turntable 16 to rotate.

[0080] The gear set 86 includes a bevel gear set 88 drivingly connected to the motor 84, a spur gear set 90 drivingly connected to the bevel gear set 88, and an external gear ring 92 drivingly connected to the spur gear set 90. The external gear ring 92 is located within the comb head 22 and is connected to the turntable 16. When the motor 84 operates, it drives the spur gear set 90 to rotate through the bevel gear set 88. The spur gear set 90 drives the external gear ring 92 to rotate, and the external gear ring 92 then drives the turntable 16 to rotate, thereby pushing the first comb tooth portion 14 and the second comb tooth portion 60 to swing.

[0081] The bevel gear set 88 includes two meshing bevel gears, and the spur gear set 90 includes two meshing spur gears. One of the bevel gears is drivingly connected to the motor 84 to rotate with the motor 84. The other bevel gear is fixedly connected to one of the spur gears through a fixed shaft so that the bevel gear and the spur gear rotate synchronously. The other spur gear meshes with the external gear ring 92.

[0082] An installation frame 94 is provided within the comb handle 20. A battery 96 and a circuit board 98 electrically connected to the battery 96 are provided on the installation frame 94. The motor 84 is installed on the installation frame 94 and is located between the battery 96 and the comb head 22. The motor 84 is electrically connected to the circuit board 98. A key 100 is provided on the comb handle 20 for the user to operate to control the start and stop of the motor 84. By providing the battery 96 within the comb handle 20, the massage comb 10 can be used without being connected to an external power source.

[0083] The specific type of the battery 96 is not limited, and it can be a rechargeable battery or a non-rechargeable battery. In this embodiment, the battery 96 is a rechargeable battery, and a charging plate 102 electrically connected to the circuit board 98 is provided in the comb handle 20, and a charging port 104 is provided at one end of the comb handle 20 away from the comb head 22. When the battery 96 is low on power, the user can insert the data cable of the charger into the charging port 104 to charge the battery 96, so that the battery 96 can be reused.

[0084] A recessed portion 106 is provided at one end of the comb handle 20 away from the comb head 22 , and a decorative piece 108 is provided in the recessed portion 106 . The decorative piece 108 can play a decorative effect, making the massage comb 10 more aesthetically pleasing.

[0085] In the massage comb provided by the present invention, when the driving mechanism drives the turntable to rotate, the first comb teeth can swing relative to the comb head under the action of the turntable, so that the end of the plurality of first comb teeth away from the turntable can be retracted inward or opened outward, imitating the action of fingers pinching, thereby forming a massage effect. Since the first comb teeth swing inward or outward relative to the comb head, compared with the method of rotating circumferentially around the comb head, the risk of the massage comb wrapping the hair around the first comb teeth can be reduced, so that the massage comb is not only suitable for users with short hair, but also for users with long hair, and has a wider range of applications. In addition, since the massage comb has a functional module, and the functional module is detachably installed in the mounting hole, the user can select a functional module with corresponding functions and install it in the mounting hole to produce corresponding effects, thereby enriching the functions of the massage comb.

[0086] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
