[0021] The technical solution provided by the application is described in detail below in conjunction with specific drawings and embodiments.

[0022] Referring to FIGS. 1-3, a massage comb 10 in accordance with an embodiment of the present invention includes a shell 12, multiple first comb tooth portions 14, a turnplate 16 and a driving mechanism 18. The multiple first comb tooth portions 14 are movably mounted on the shell 12. The multiple first comb tooth portions 14 are connected to the turnplate 16 and driven by the turnplate 16. The turnplate 16 is rotatably mounted in the shell 12. The driving mechanism 18 is mounted in the shell 12 and connected to the turnplate 16 to drive the turnplate 16 to rotate with respect to the shell 12 so as to drive ends, away from the turnplate 16, of the multiple first comb tooth portions 14 to gather together inwards or spread apart outwards. When the driving mechanism 18 drives the turnplate 16 to rotate, the turnplate 16 will drive the multiple first comb tooth portions 14 to swing to allow the ends, away from the turnplate 16, of the multiple first comb tooth portions 14 to gather together inwards or spread apart outwards to simulate scratching and pinching motions of fingers to fulfill a massage effect, such that the massage comb 10 not only fulfils a hair combing function by means of the multiple first comb tooth portions 14, but also fulfils a massage effect by means of the first comb tooth portions 14, thus enriching the functions of the massage comb 10. Moreover, since the first comb tooth portions 14 swing with respect to the shell 12, compared with comb teeth that rotate around a comb head in the circumferential direction, hairs of users are less likely to be entangled onto the first comb tooth portions 14 of the massage comb 10, such that the massage comb 10 is suitable for both users with long hairs and users with short hairs and has a wider application range.

[0023] The shell 12 includes a comb handle 20 to be held by users and a comb head 22 fixed to an end of the comb handle 20. The turnplate 16 is movably mounted in the comb head 22. The first comb tooth portions 14 are movably mounted on the comb head 22, and the ends, away from the turnplate 16, of the first comb tooth portions 14 extend out of the comb head 22 in order to come in contact with the head of users.

[0024] 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 an axial direction of the housing 24 is perpendicular to an axial direction of the comb handle 20.

The turnplate 16 is movably mounted in the housing 24 and located between the mounting structure 26 and the housing 24, and the multiple first comb tooth portions 14 are movably mounted on the mounting structure 26. The driving mechanism 18 is configured to drive the turnplate 16 to rotate in the housing 24 to thereby drive the multiple first comb tooth portions 14 to swing with respect to the mounting structure 26.

[0025] The mounting structure 26 includes a first comb tooth cover 28 and a second comb tooth cover 30 connected to one side of the first comb tooth cover 28. The turnplate 16 is located on a side, away from the second comb tooth cover 30, of the first comb tooth cover 28. Parts of the first comb tooth portions 14 are sandwiched between the first comb tooth cover 28 and the second comb tooth cover 30 and are rotatable with respect to the first comb tooth cover 28 and the second comb tooth cover 30, such that the multiple first comb tooth portions 14 are movably mounted on the mounting structure 26.

[0026] The comb head 22 further includes a protective cover 32, and the protective cover 32 is located on a side, away from the first comb tooth cover 28, of the second comb tooth cover 30 and is in sealed connection with the housing 24. The mounting structure 26 is located between the housing 24 and the protective cover 32, and the ends, away from the turnplate 16, of the multiple first comb tooth portions 14 extend out of the protective cover 32. The protective cover 32 may prevent the mounting structure 26 from being exposed, such that the massage comb 10 is more aesthetic, and the sealing performance of the massage comb 10 is improved; and hairs are prevented from being entangled into the massage comb 10, such that the safety of the massage comb 10 in use is improved.

[0027] The specific method for realizing sealing between the protective cover 32 and the housing 24 is not limited. For example, a sealing ring may be arranged between the protective cover 32 and the housing 24, or a sealant may be arranged between the protective cover 32 and the housing 24.

[0028] The specific material of the protective cover 32 is not limited. In this embodiment, the protective cover 32 is a silica gel cover.

[0029] As shown in FIG. 1, in some embodiments, the massage comb 10 further includes a functional module, a mounting portion is arranged on the comb head 22, the functional module is mounted to the mounting portion, and the multiple first comb tooth portions 14 are arranged around the functional module. The functional module includes, but not limited to, one of an essential oil module 110, a hot compress module 112 and an atomization module 114, such that the massage comb 10 not only has a hair combing function and a massage function, but also has a corresponding function of the functional module, thus further enriching the functions of the massage comb 10.

[0030] In this embodiment, the mounting portion is a mounting hole 116 extending through the comb head 22, and the functional module is detachably mounted in the mounting hole 116. By mounting the functional module in the mounting hole 116, the incongruity of the functional module may be reduced, and users may replace the functional module easily.

[0033] Referring to FIGS. 3 and 7, in one embodiment, the multiple first comb tooth portions 14 are sequentially connected end-to-end in a rotation direction of the turnplate 16 to form a ring, and every two adjacent first comb tooth portions 14 are movably connected. In this way, under the action of the turnplate 16, the multiple first comb tooth portions 14 are able to swing with respect to the comb head 22 and every two adjacent first comb tooth portions 14 are able to move relatively to allow the ends, away from the turnplate 16, of the multiple first comb tooth portions 14 to synchronously gather together inwards or spread apart outwards. The multiple first comb tooth portions 14 are connected end-to-end to form a ring, and compared with a spaced arrangement of the multiple first comb tooth portions 14, the space on the shell 12 is fully used to arrange more first comb tooth portions 14, such that the contact area between the massage comb 10 and the head of users and the massage area of the massage comb 10 are enlarged, thus improving user experience.

[0034] In another embodiment, the multiple first comb tooth portions are arranged at intervals in the rotation direction of the turnplate.

[0035] In some embodiments, a first cam structure 34 is arranged on a side, close to first comb tooth portions 14, of the turnplate 16, first bumps 36 are arranged on the first comb tooth portions 14, and the multiple first comb tooth portions 14 are movably engaged with the first cam structure 34 respectively by means of the corresponding first bumps 36. When the turnplate 16 is driven by the driving mechanism 18 to rotate, the first cam structure 34 rotates with the turnplate 16, and in the rotation process, the first cam structure 34 drives the multiple first comb tooth portions 14 to swing by means of the first bumps 36 to allow the ends, away from the turnplate 16, of the multiple first comb tooth portions 14 to gather together inwards or spread apart outwards.

[0036] The first cam structure 34 may be one or more cams mounted on the turnplate 16 or may be a cam slot formed in the turnplate 16.

[0037] In this embodiment, the first cam structure 34 is a first cam slot, the first bumps 36 are arranged on the first comb tooth portions 14, and ends, away from the first comb tooth portions 14, of the first bumps 36 are movably inserted into the first cam slot. When the turnplate 16 rotates, the first cam slot rotates with respect to the first bumps 36, and a slot wall of the first cam slot pushes the first bumps 36 to swing to drive the first comb tooth portions 14 to swing.

[0038] The first comb tooth portion 14 includes a driving comb tooth portion 38 and a driven comb tooth portion 40, multiple driving comb tooth portions 38 and multiple driven comb tooth portions 40 are movably mounted on the comb head 22. The multiple driving comb tooth portions 38 and the multiple driven comb tooth portions 40 are distributed alternately in the rotation direction of the turnplate 16 and movably connected to form a ring. The first bumps 36 are arranged on the driving comb tooth portions 38, that is, the driving comb tooth portions 38 are in movable engagement with the turnplate 16 by means of the first bumps 36 being clearance-fitted in the first cam slot, such that when the turnplate 16 rotates, the driving comb tooth portions 38 are able to swing with respect to the comb head 22 under the action of the first cam slot and the first bumps 36 and drive the driven comb tooth portions 40 to swing with respect to the comb head 22, thus making ends, away from the turnplate 16, of the driving comb tooth portions 38 and the driven comb tooth portions 40 synchronously gather together inwards or spread apart outwards.

[0039] Each of the driving comb tooth portion 38 and the driven comb tooth portion 40 includes a first base 42 and first comb teeth 44 connected to the first base 42. The first base 42 of the driving comb tooth portion 38 is movably connected to the first base 42 of the driven comb tooth portion 40. The first bases 42 are rotatably mounted in the comb head 22, the first comb teeth 44 extend out of the comb head 22 from the first bases 42 in a direction away from the turnplate 16, and the first bumps 36 are arranged on the first bases 42 of the driving comb tooth portions 38 and extend in a direction away from the first comb teeth 44. Specifically, the first bases 42 are movably sandwiched between the first comb tooth cover 28 and the second comb tooth cover 30. The ends, away from the first comb teeth 44, of the first bumps 36 extend through the first comb tooth cover 28 to be movably inserted into the first cam slot. The ends, away from the first bumps 36, of the first comb teeth 44 extend through the second comb tooth cover 30 and the protective cover 32 and then extend to outside of the protective cover 32. When the driving mechanism 18 drives the turnplate 16 to rotate, the turnplate 16 drives the first bumps 36 to swing by means of the first cam slot, then the first bumps 36 drive the first bases 42 connected thereto to move, the first bases 42 drive the first bases 42 of the driven comb tooth portions 40 connected thereto to rotate, the first bases 42 of the driving comb tooth portions 38 and the driven comb tooth portions 40 drive the corresponding first comb teeth 44 to move, whereby the ends, away from the first bases 42, of the first comb teeth 44 are driven to gather together inwards or spread apart outwards.

[0040] The number of the first comb teeth 44 on each first base 42 is not limited and may be one or more. In this embodiment, multiple first comb teeth 44 are arranged on each first base 42 at intervals.

[0041] The first bumps 36, the first bases 42 of the driving comb tooth portions 38 and the first comb teeth 44 of the driving comb tooth portions 38 may be formed integrally or formed separately and then assembled together. In this embodiment, the first bumps 36, the first bases 42 of the driving comb tooth portions 38 and the first comb teeth 44 of the driving comb tooth portions 38 are preferably formed integrally, such that the connection strength is improved, and the assembly process is omitted. Similarly, the first bases 42 and the first comb teeth 44 of the driven comb tooth portions 40 may be formed integrally or assembled together by separate parts.

[0042] Referring to FIGS. 8-10, support bases 46 matched with the first bases 42 are arranged on the comb head 22, support holes 48 are formed in the support bases 46, and opposite two ends of each first base 42 are rotatably received in the support holes 48 of the corresponding support bases 46 respectively, such that the first bases 42 of the driving comb tooth portions 38 and the driven comb tooth portions 40 are able to rotate with respect to the comb head 22 around central axes of the support holes 48 under the action of the first bumps 36 and the first cam slot. Specifically, in this embodiment, the first bases 42 and the support holes 48 are cylindrical, such that after the ends of the first bases 42 are inserted into the support holes 48, a running fit effect is realized.

[0043] Multiple first receiving grooves 50 for receiving the first bases 42 are formed between the first comb tooth cover 28 and the second comb tooth cover 30. The multiple first receiving grooves 50 are spaced apart from each other. Each support base 46 is located between two adjacent first receiving grooves 50, and each support hole 40 connects two adjacent first receiving grooves 50.

When the turnplate 16 rotates, the second cam slot rotates with respect to the second bumps 64, and the slot walls of the second cam slot drive the second bumps 64 to swing to thereby drive the second comb tooth portions 60 to swing.

[0056] Each second comb tooth portion 60 includes a second base 66 and second comb teeth 68 connected to the second base 66, the second bases 66 are movably mounted on the mounting structure 26, the second comb teeth 68 extend out of the comb head 22 from the second bases 66 in a direction away from the turnplate 16, and the second bumps 64 are arranged on the second bases 66 and extend in a direction away from the second comb teeth 68. When the turnplate 16 rotates, the second cam slot drives the second bumps 64 to swing, and consequently the second bumps 64 drive the second bases 66 and the second comb teeth 68 to move with respect to the mounting structure 26, whereby, the ends, away from the second bases 66, of the second comb teeth 68 are driven to gather together inwards or spread apart outwards.

[0057] The specific number of the second comb teeth 68 on each second base 66 is not limited and may be one or more. In this embodiment, multiple second comb teeth 68 are arranged on each second base 66 at intervals.

[0058] The second bumps 64, the second bases 66 and the second comb teeth 68 may be formed integrally or assembled together by separate parts. In this embodiment, the second bumps 64, the second bases 66 and the second comb teeth 68 are preferably formed integrally, such that the connection strength is improved, and the assembly process is omitted.

[0059] As shown in FIGS. 9 and 10, multiple second receiving grooves 70 for receiving the second bases 66 are formed between the first comb tooth cover 28 and the second comb tooth cover 30, and the multiple second receiving grooves 70 are spaced apart from each other. Two ends of each second receiving groove 70 are concaved to form shaft holes 72, and shafts 74 are respectively arranged at two ends of each second base 66 and inserted into the corresponding shaft holes 72, such that the second comb tooth portions 60 are rotatably mounted to the comb head 22.

[0060] The first comb tooth cover 28 is provided with third recesses 76 in communication with the second receiving grooves 70, the second comb tooth cover 30 is provided with fourth recesses 78 in communication with the second receiving grooves 70, ends, away from the second bases 66, of the second bumps 64 extend through the third recesses 76 and are movably inserted into the second cam slot, and ends, away from the second bases 66, of the second comb teeth 68 extend through the fourth recesses 78 and extend out of the comb head 22.

[0061] As shown in FIGS. 3 and 6, in some embodiments, multiple second comb tooth portions 60 correspond to multiple driving comb tooth portions 38 in a radial direction of the turnplate (i.e., a direction perpendicular to a rotation axis of the turnplate 16), and the second comb tooth portions 60 and the corresponding driving comb tooth potions 38 are driven by the turnplate 16 to swing synchronously in the same direction, such that mutual interference between the second comb tooth portions 60 and the first comb tooth portions 14 in the swing process is avoided.

[0062] The first cam slot and the second cam slot are ring-shaped and wavy, and each of the first cam slot and the second cam slot includes multiple peaks 80 and troughs 82 which are distributed alternately.

[0063] The first cam slot and the second cam slot are identical in shape, and the peaks 80 and troughs 82 of the first cam slot are in one-to-one correspondence with the peaks 80 and troughs 82 of the second cam slot, that is, in a radial direction of the first cam slot, the multiple peaks 80 of the first cam slot are in one-to-one correspondence with the multiple peaks 80 of the second cam slot, and the multiple troughs 82 of the first cam slot are in one-to-one correspondence with the multiple troughs 82 of the second cam slot; the multiple second comb tooth portions 60 are in one-to-one correspondence with the multiple driving comb tooth portions 38, and the first bumps 36 are spaced apart from and parallel to the second bumps 64, such that when the turnplate 16 rotates, the driving comb tooth portions 38 and the second comb tooth portions will be driven by the turnplate 16 to swing synchronously in the same direction, thus avoiding the problem of mutual interference caused by different swing directions of the driving comb tooth portions 38 and the second comb tooth portions.

[0064] In some embodiments, the number of the peaks 80 of the first cam slot is the same as the number of the troughs 82 of the first cam slot, the number of the peaks 80 of the second cam slot is the same as the number of the troughs 82 of the second cam slot, the number of the peaks 80 of the first cam slot is the same as the number of the peaks 80 of the second cam slot, and the number of the driving comb tooth portions 38 and the number of the second comb tooth portions 60 are the same as the number of the peaks 80 of the first cam slot.

[0065] A distance from the middle of the first cam slot (the middle position that is equidistant from two slot walls of the first cam slot in the radial direction) to the central axis of the turnplate 16 in the radial direction is in a sine relation with an inclination angle of the first bumps 36, and a distance from the middle of the second cam slot to the central axis of the turnplate 16 in the radial direction is in a sine relation with an inclination angle of the second bumps 64. With the first cam slot as an example, the distance from the middle of the first cam slot to the central axis of the turnplate in the radial direction is L= a×sinθ+b, wherein a is a distance from the central axes of the first bases 42 to the ends, away from the first bases 42, of the first bumps 36, θ is the inclination angle of the first bumps 36 with respect to a vertical direction, and b is a radial distance from the central axes of the first bases 42 to the central axis of the turnplate 16.

[0066] Referring to FIGS. 2, 3 and 11, in some embodiments, the driving mechanism 18 includes a motor 84 and a gear set 86 in transmission connection with the motor 84. The motor 84 is located in the comb handle 20 of the shell 12, and the gear set 86 is connected to the turnplate 16 in order to drive the turnplate 16 to rotate.

[0067] The gear set 86 includes a bevel gear set 88 in transmission connection with the motor 84, a spur gear set 90 in transmission connection with the bevel gear set 88, and an outer gear ring 92 in transmission connection with the spur gear set 90, and the outer gear ring 92 is located in the comb head 22 and connected to the turnplate 16. When operating, the motor 84 drives the spur gear set 90 to rotate by means of the bevel gear set 88, the spur gear set 90 drives the outer gear ring 92 to rotate, the outer gear ring 92 drives the turnplate 16 to rotate, and the first comb tooth portions 14 and the second comb tooth portions 60 are driven to swing.

[0068] The bevel gear set 88 includes two bevel gears that are meshed with each other, and the spur gear set 90 includes two spur gears that are meshed with each other, wherein one of the bevel gears is in transmission connection with the motor 84 to rotate with the motor 84, and the other bevel gear is fixedly connected to one of the spur gears by means of a stationary shaft such that the one of the spur gears can rotate synchronously with the other bevel gear, and the other spur gear is meshed with the outer gear ring 92.

[0069] A mount 94 is arranged in the comb handle 20, a battery 96 and a circuit board 98 electrically connected to the battery 96 are arranged on the mount 94, the motor 84 is mounted on the mount 94 and located between the battery 96 and the comb head 22, and the motor 84 is electrically connected to the circuit board 98. A key 100 is arranged on the comb handle 20, and the key 100 is configured to be operated by users to control the motor 84 to start or shut down. By means of the battery 96 arranged in the comb handle 20, the massage comb 10 may be used without an external power supply.

[0070] The specific type of the battery 96 is not limited, and the battery 96 may be a rechargeable battery or a non-rechargeable battery. In this embodiment, the battery 96 may be a rechargeable battery, a charging board 102 electrically connected to the circuit board 98 is arranged in the comb handle 20, and a charging port 104 is formed in an end, away from the comb head 22, of the comb handle 20. When the state of charge of the battery 98 is low, users may plug a data line of a charger into the charging port 104 to charge the battery 96, thus making the battery 96 reusable.

[0071] A concaved portion 106 is arranged at an end, away from the comb head 22, of the comb handle 20, a decoration 108 is arranged in the concaved portion 106, and the decoration 108 has a decoration effect to make the massage comb 10 more aesthetic.

[0072] According to the massage comb provided by the application, when the driving mechanism drives the turnplate to rotate, the first comb tooth portions swing with respect to the comb head under the action of the turnplate, such that the ends, away from the turnplate, of the multiple first comb tooth portions gather together inwards or spread apart outwards to simulate pinching motions of fingers to fulfill a massage effect. Because the first comb tooth portions swing inwards or outwards with respect to the comb head, compared with comb teeth that rotate around a comb head in the circumferential direction, hairs are less likely to be entangled onto the first comb tooth portions of the massage comb, such that the massage comb is suitable for both users with short hairs and users with long hairs and has a wider application range. In addition, because the massage comb is provided with the functional module that is detachably mounted in the mounting hole, users may mount the functional module with a corresponding function in the mounting hole to fulfill a corresponding effect, thus enriching the functions of the massage comb.

[0073] The above embodiments are merely optional embodiments of the application and are not used to limit the application. For those skilled in the art, various modifications and transformations may be made to the application. Any amendments, equivalent substitutions and improvements made based on the spirit and principle of the application should also fall within the scope of the claims of the application.
