[0001] The utility model relates to the technical field of portable head massage devices, in particular to an opening and closing driving mechanism for a massage comb. Background Art

[0002] Since ancient times, Chinese medicine has been well aware of the richness of acupuncture points on the head. They are dotted on the top of the head like stars, and contain great potential for regulating the circulation of qi and blood in the human body. Through clever massage techniques, we can dredge the meridians, relieve stress, and deeply relax and nourish the body and mind. With the development of science and technology, people have invented many massage devices in order to enjoy the benefits of head massage more conveniently. Among them, the helmet-type massager is one of the most representative products. It has a large structure and a comprehensive design. It can cover multiple acupuncture points on the head and bring users a full range of massage experience. However, because of its large size, it is quite inconvenient to carry and use, which is undoubtedly a limitation in the fast-paced modern society.

[0003] Handheld massagers are lighter and easier to carry. For example, Chinese patent No. 202223327578.7 discloses a racket-shaped comb with a massage function. The comb teeth open and close radially while combing the hair, and the ends of the comb teeth move on the scalp to achieve the massage function. However, due to the limitation of its annular shaft structure, there is a problem of jamming, and the opening and closing force is weak, which is difficult to meet the needs of users with greater massage strength. In addition, the assembly is difficult and the cost is high, which needs to be improved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an opening and closing driving mechanism for a massage comb, which has low assembly difficulty, smooth structure, high reliability and significantly improved massage driving force.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a massage comb opening and closing drive mechanism, the massage comb opening and closing drive mechanism comprises an annular shell, a groove wheel plate movably mounted on the annular shell, a reduction motor assembly for driving the groove wheel plate to rotate and an annular bracket covered on the upper side of the annular shell, the groove wheel plate is located in an annular space formed by the annular shell and the annular bracket, a cam groove is provided on the upper side of the groove wheel plate, and the annular bracket is annularly arranged with a plurality of radially swingable swinging members, the lower end of the swinging member is movably connected to a radial connecting rod, and the other end of the radial connecting rod is movably embedded in the cam groove.

[0006] Preferably, a plurality of radial sliding grooves are arranged in an annular shape on the upper side surface of the annular shell, and the radial connecting rods are movably embedded in the radial sliding grooves.

[0007] Preferably, the middle section and the lower end of the swinging member are respectively provided with a fulcrum shaft and a linkage shaft, the annular bracket is provided with a plurality of through holes arranged in a ring, and the two side walls of the through holes are provided with axial holes, the swinging member passes through the through holes, and the two ends of the fulcrum shaft are embedded in the axial holes; the inner end of the radial connecting rod is provided with an axial long hole, and the linkage shaft is movably embedded in the axial long hole.

[0008] Preferably, the reduction motor assembly includes a motor seat located on the side of the annular shell and integrally formed with the annular shell, an output gear located on the lower middle side of the annular shell, a drive motor and a reduction wheel group for transmitting the force of the drive motor to the output gear, the output gear is fixedly connected to the groove pulley, and a reduction bin cover covering the drive motor, the output gear and the reduction wheel group is installed on the lower side of the annular shell.

[0009] Preferably, the reduction gear set includes a worm fixed to the main shaft of the driving motor, a worm wheel meshing with the worm, a first pinion fixed to the worm wheel, a first large gear meshing with the first pinion, a second pinion fixedly connected to the first large gear, a second large gear meshing with the second pinion, and a third pinion fixedly connected to the second large gear, and the third pinion is meshingly connected to the output gear.

[0010] The beneficial effects of the utility model are as follows: the utility model provides an opening and closing drive mechanism for a massage comb. When applied to a massage comb, the comb teeth are fixed to the outer end of the swinging member. When the reduction motor assembly is working, it drives the groove wheel disk to rotate to drive the radial connecting rod to move back and forth. When the radial connecting rod reciprocates, it drives the lower end of the swinging member to swing radially, thereby realizing the opening and closing drive function of the annularly arranged comb teeth to contract inwardly and expand outwardly synchronously. Due to the structural design of the radial connecting rod, the rotation of the groove wheel disk and the reciprocating movement of the radial connecting rod are smoother, the distance between the lower end of the swinging member and the swing fulcrum is longer, and the torque of the driving end is larger, thereby effectively improving the swinging torque of the outer end of the swinging member under the premise of the same motor output torque, thereby realizing high-force massage of the comb tooth end, with high reliability, low assembly difficulty and strong practicality.

[0016] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0017] like Figures 1 to 5 As shown, a massage comb opening and closing drive mechanism comprises an annular shell 1, a grooved wheel plate 2 movably mounted on the annular shell 1, a reduction motor assembly 3 for driving the grooved wheel plate 2 to rotate, and an annular bracket 4 covered on the upper side of the annular shell 1, the grooved wheel plate 2 is located in an annular space formed by the annular shell 1 and the annular bracket 4, a cam groove 21 is provided on the upper side of the grooved wheel plate 2, and the annular bracket 4 is annularly arranged with a plurality of radially swingable swinging members 5, the lower end of the swinging member 5 is movably connected to a radial connecting rod 6, and the other end of the radial connecting rod 6 is movably embedded in the cam groove 21.

[0018] The opening and closing drive mechanism of the utility model is applied to a massage comb, and the comb teeth are fixed to the outer end of the swinging member 5. When the reduction motor assembly 3 is working, it drives the groove wheel plate 2 to rotate, so as to drive the radial connecting rod 6 to move back and forth. When the radial connecting rod 6 reciprocates, it drives the lower end of the swinging member 5 to swing radially, thereby realizing the opening and closing drive function of the annularly arranged comb teeth to contract inwardly and expand outwardly synchronously. Due to the structural design of the radial connecting rod 6, the rotation of the groove wheel plate 2 and the reciprocating movement of the radial connecting rod 6 are smoother, the distance between the lower end of the swinging member 5 and the swing fulcrum is longer, and the torque of the driving end is larger, thereby effectively improving the swinging torque of the outer end of the swinging member 5 under the premise of the same motor output torque, thereby realizing a large-force massage of the comb tooth end, with high reliability, low assembly difficulty and strong practicality.

[0019] In this embodiment, a plurality of radial grooves 11 are arranged in an annular manner on the upper side surface of the annular shell 1, and the radial connecting rod 6 is movably embedded in the radial groove 11. The design of the radial groove 11 greatly improves the smoothness of the internal movable parts, effectively prevents the radial connecting rod 6 from being stuck due to lateral deviation, and has higher reliability.

[0020] In this embodiment, the middle section and the lower end of the swing member 5 are respectively provided with a fulcrum shaft 51 and a linkage shaft 52, the annular bracket 4 is provided with a plurality of through holes 42 arranged in a ring, and the two side walls of the through holes 42 are provided with shaft holes 43, the swing member 5 passes through the through holes 42, and the two ends of the fulcrum shaft 51 are embedded in the shaft holes 43; the inner end of the radial connecting rod 6 is provided with an axial long hole 61, and the linkage shaft 52 is movably embedded in the axial long hole 61. When the swing member 5 makes radial swing, only the fulcrum shaft 51 and the linkage shaft 52 rotate in the corresponding shaft holes. The design of the fulcrum shaft 51 and the linkage shaft 52 effectively reduces the friction contact area of ​​the movable parts and the friction resistance between the internal components, further avoiding the problem of internal components being stuck, and has strong practicality.

[0021] In this embodiment, the reduction motor assembly 3 includes a motor seat located at the side of the annular housing 1 and formed integrally with the annular housing 1, an output gear 31 located at the lower middle part of the annular housing 1, a drive motor 32 and a reduction wheel group for transmitting the force of the drive motor 32 to the output gear 31, the output gear 31 is fixedly connected to the groove wheel plate 2, and a reduction chamber cover 33 covering the drive motor 32, the output gear 31 and the reduction wheel group is installed on the lower side of the annular housing 1. Specifically, the reduction wheel group includes a worm 34 fixed to the main shaft of the drive motor 32, a worm wheel 35 meshing with the worm 34, a first pinion 36 fixed to the worm wheel 35, a first large gear 37 meshing with the first pinion 36, a second pinion 38 fixedly connected to the first large gear 37, a second large gear 39 meshing with the second pinion 38, and a third pinion 30 fixedly connected to the second large gear 39, and the third pinion 30 is meshingly connected with the output gear 31. The motor seat is arranged on the side of the annular shell 1, and the driving motor 32 can be arranged in the handle of the massage comb, which no longer occupies the internal space and thickness of the opening and closing driving mechanism. The structural design of the opening and closing driving mechanism is more compact and smaller in size. The massage comb is exquisite and beautiful, and is very popular with users.
