As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0027] Combination Figures 1 to 8 As shown, this application provides a massage comb, including: a comb handle body 1, a comb head assembly 2, a drive device 3, an electrical stimulation device 4, and a power supply device 5; The comb assembly 2 is movably mounted on the comb handle body 1 and has at least two massage modes; The comb handle body 1 is the main handhold part of the massage comb and belongs to the outer shell skeleton of the massage comb product. The comb head assembly 2 is used to comb the hair and come into contact with the scalp. It is a movable module assembled at the front end of the comb handle body 1 to realize the massage function.

[0028] The drive device 3 is installed inside the comb handle body 1 and drives the comb head assembly 2 so that the comb head assembly 2 reciprocates relative to the comb handle body 1 in a preset direction, so that the comb head assembly 2 has a first massage mode. For example, the drive device 3 can be a combination of a micro motor, an eccentric wheel, and a connecting rod. The eccentric wheel is connected to the output shaft of the micro motor, and the oscillation amplitude is determined by the eccentricity. One end of the connecting rod is hinged to the eccentric force point of the eccentric wheel, and the other end is hinged to the comb assembly 2. Alternatively, the drive device 3 can be a combination of a micro motor, a cam, and a swing arm. The output shaft of the micro motor is connected to the eccentric wheel structure, one end of the swing arm is against the cam profile, and the other end is connected to the comb assembly 2. The drive device 3 can also be a direct electric push rod structure. Of course, there are no restrictions on the specific implementation structure of the drive device 3.

[0029] An electrical stimulation device 4 is disposed within the comb assembly 2 and is used to electrically connect the comb assembly 2 so that when the comb handle body 1 is held by the user and the comb assembly 2 contacts the user's head, an electric current circuit is formed through the user's body, so that the comb assembly 2 has a second massage mode; and is used to disconnect the electric current circuit when the comb assembly 2 is removed from the user's head. For example, the electrical stimulation device 4 may include a pulse signal generation module, a boost drive circuit, and an output motor. The pulse signal generation module may be a microcontroller or an EMS / TENS chip, responsible for generating low-voltage pulses with a set frequency, duty cycle, and waveform. The boost drive circuit may include a charge pump or a transformer. The output electrodes may reuse the comb teeth from the comb assembly 2, and may be made of conductive silicone, coated metal, or stainless steel to form a circuit and output pulses upon contact with the scalp. Of course, the specific composition and structure of the electrical stimulation device 4 are not limited.

[0030] The power supply device 5 is electrically connected to the drive device 3 and the electrical stimulation device 4 to supply power to the drive device 3 and the electrical stimulation device 4.

[0031] For example, the power supply device 5 may be a lithium polymer battery, and a charging interface 11 connected to the power supply device 5 may be provided on the comb handle body 1, and a corresponding protection circuit may be provided.

[0032] More specifically, the massage comb also has a control circuit board 7 inside and a function button 12 on the comb handle body 1, which is used to control the start and stop of the drive device 3 and the electrical stimulation device 4, and realize functions such as mode switching and intensity adjustment.

[0033] Understandably, the drive device 3 drives the comb assembly 2 to reciprocate relative to the comb handle body 1 in a preset direction, so that the comb assembly 2 has a first massage mode; the electrical stimulation device 4 is used to electrically connect to the comb assembly 2 so that when the comb handle body 1 is held by the user and the comb assembly 2 contacts the user's head, a current circuit is formed through the user's body, so that the comb assembly 2 has a second massage mode; the integration of physical swing massage function and electrical stimulation massage function is realized, breaking through the limitations of a single massage mode, which helps to deeply integrate physical touch and nerve stimulation, and has a three-dimensional and rich massage feeling.

[0034] Both the first and second massage modes can be used independently or in combination. When the user activates the first massage mode, the drive device 3 drives the comb assembly 2 to oscillate back and forth, simulating the action of hand combing and massaging, providing a realistic physical kneading sensation. In addition, the second massage mode can be activated, where the electrical stimulation device 4 forms a closed circuit through the comb assembly 2 and contacts the scalp, releasing pulsed current. The combined use of the first and second massage modes not only promotes blood circulation in the scalp through physical friction but also allows microcurrents to penetrate the surface and reach nerve endings, solving the problems of insufficient penetration in simple physical massage and lack of realism in simple electrical stimulation. This greatly enriches the massage experience and meets the diverse and personalized massage needs of users.

[0035] Both the first and second massage modes are implemented through the combing head component 2. The functions of the combing head component 2 are reused. For example, the combing head component 2 is used to make direct contact with the user's head and is the execution end of the physical massage. In addition, the combing head component 2 also serves as the current output end of the electrical stimulation massage, thereby simplifying the internal layout of the massage comb and realizing a compact design.

[0036] Furthermore, the triggering condition for the second massage mode is: the comb handle body 1 is held by the user and the comb head component 2 is in contact with the user's head. On the one hand, in the first massage mode, the comb head component 2 continuously performs reciprocating motion, ensuring dynamic contact between the comb teeth or the surface of the comb head component 2 and the scalp, forming continuous physical contact. This can significantly reduce contact resistance, ensuring stable conduction of the current circuit, thereby making the electrical stimulation output more uniform and continuous. On the other hand, the second massage mode is only activated when the user holds the comb handle body 1 and the comb head component 2 is in contact with the user's head. This can, to a certain extent, avoid accidental triggering of the electrical stimulation current, improve safety, and also enhance the battery life of the massage comb.

[0037] In an optional embodiment, combined with Figure 1 , Figures 3 to 7 As shown, the comb assembly 2 includes: a connecting seat 23, a comb tooth base 24, a first comb tooth 21, and a second comb tooth 22; The first comb tooth 21 and the second comb tooth 22 are disposed on the comb tooth base 24. The electrical stimulation device 4 is disposed in the comb tooth base 24 for being electrically connected to the first comb tooth 21 and the second comb tooth 22, and the first comb tooth 21 and the second comb tooth 22 are arranged with opposite polarities. Each first comb tooth 21 has at least one adjacent second comb tooth 22 to form a current circuit for electrical stimulation massage between the first comb tooth 21 and the second comb tooth 22. The connecting seat 23 is disposed inside the comb handle body 1 and is connected to the comb tooth base 24 via the extension shaft 25, so that at least the comb tooth base 24, the first comb tooth 21 and the second comb tooth 22 are located outside the comb handle body 1. The connecting seat 23 is driven to connect with the driving device 3 so that the comb assembly 2 is in the first motion mode, and the first comb tooth 21 and the second comb tooth 22 have at least the first motion mode.

[0038] Specifically, in some embodiments of this application, the first comb tooth 21 and the second comb tooth 22 are made of conductive silicone material. Of course, there are no restrictions on the materials used for the first comb tooth 21 and the second comb tooth 22.

[0039] The conductive silicone has a certain degree of elasticity. When the massage comb is working, the comb head assembly 2 swings back and forth. The tips of the first comb teeth 21 and the second comb teeth 22 will adapt to the slight deformation of the scalp curvature to simulate the feel of the fingertips. The contact between the first comb teeth 21 and the second comb teeth 22 and the scalp is a soft contact. When swinging and pressing, the contact area between the first comb teeth 21 and the second comb teeth 22 and the scalp is larger, the contact resistance is lower and more stable, and the current density of the electrical stimulation output is uniform, reducing the needle-like sensation caused by the concentration of local current during electrical stimulation massage.

[0040] Understandably, the first comb tooth 21 can be set as the anode and the second comb tooth 22 as the cathode. Similarly, the first comb tooth 21 can be set as the cathode and the second comb tooth 22 as the anode. Each first comb tooth 21 has at least one adjacent second comb tooth 22. The first comb tooth 21 and the adjacent second comb tooth 22 can form a uniform multi-point polarized electric field in a local small area of ​​scalp contact, making the current density distribution more uniform. This can avoid the stinging sensation caused by excessive current concentration to a certain extent, and can also avoid the problem of current dispersion and weak stimulation caused by large-area contact to a certain extent. This significantly improves the convenience and comfort of use, and can achieve the effect of multi-point simultaneous regulation similar to acupuncture in traditional Chinese medicine.

[0041] The connecting seat 23 is located inside the comb handle body 1 and is connected to the comb tooth base 24 via the extension shaft 25. This facilitates the structural design of the comb head assembly 2 and optimizes the structural layout of the massage comb. The electrical stimulation device 4 is concealed inside the comb tooth base 24, which significantly shortens the transmission path of the high-voltage pulse signal. This reduces the attenuation and electromagnetic radiation of the high-voltage pulse during transmission through long wires and, to some extent, avoids interference with the main control circuit inside the comb handle body 1. Furthermore, the connection points between the first comb tooth 21, the second comb tooth 22, and the electrical stimulation device 4 are enclosed inside the comb tooth base 24, which helps extend the service life of the massage comb.

[0042] In an optional embodiment, such as Figure 6 As shown, an elastic connector 28 is provided between the comb base 24 and at least a portion of the first comb teeth 21 and / or the second comb teeth 22, so that at least a portion of the first comb teeth 21 and / or the second comb teeth 22 have a second mode of movement relative to the comb base 24; Wherein, when at least some of the first comb teeth 21 and / or the second comb teeth 22 are subjected to external force, the elastic connector 28 is compressed, and the first comb teeth 21 and / or the second comb teeth 22 can move toward the direction of the electrical stimulation device 4 so as to contact and electrically connect with the electrical stimulation device 4. After at least some of the first comb teeth 21 and / or the second comb teeth 22 are removed by external force, the elastic connector 28 is restored, and the first comb teeth 21 and / or the second comb teeth 22 can move away from the location of the electrical stimulation device 4 to disengage from the electrical stimulation device 4 and disconnect the electrical connection.

[0043] Optionally, an insulating protective layer may be provided on the elastic connector 28. If the elastic connector 28 is provided between the comb base 24 and both the first comb tooth 21 and the second comb tooth 22, then both the first comb tooth 21 and the second comb tooth 22 may have the second movement mode. If both the first comb tooth 21 and the second comb tooth 22 are fixedly connected to the comb base 24, then the first comb tooth 21 and the second comb tooth 22 may maintain an electrical connection with the electrical stimulation device 4. In this case, neither the first comb tooth 21 nor the second comb tooth 22 may have the second movement mode. If one of the first comb tooth 21 and the second comb tooth 22 is connected to the comb base 24 through the elastic connector 28, and the other is fixedly connected to the comb base 24, then only one of the first comb tooth 21 and the second comb tooth 22 may have the second movement mode.

[0044] Understandably, at least some of the first comb teeth 21 and the second comb teeth 22 are connected to the comb tooth base 24 via the elastic connector 28. The elastic connector 28 can be used to automatically reset when the comb assembly 2 is removed from the scalp pressure, so that the first comb teeth 21 and the second comb teeth 22 move away from the electric stimulation device 4, thereby physically cutting off the current circuit and enhancing the safety of the massage comb.

[0045] Furthermore, through the setting of the elastic connector 28, the actual part in contact with the head can be passively filtered out among multiple sets of first comb teeth 21 and second comb teeth 22. Only when the first comb teeth 21 and second comb teeth 22 are compressed and connected to the electrical stimulation device 4 can they participate in the electrical stimulation output. The selective conduction triggered by pressure helps to ensure that the electrical stimulation current only acts on the effective electrode area that actually contacts the scalp, avoiding ineffective power consumption and static electricity accumulation that may be caused by suspended electrodes. On the other hand, the floating design of the first comb teeth 21 and second comb teeth 22 realizes adaptive adjustment of contact pressure, which can adapt to the changes in the curvature of the head to a certain extent, so that the combing component 2 can maintain a gentle contact with the head. The first comb teeth 21 and second comb teeth 22 have both the first and second movement modes, with a high degree of freedom of movement, making the physical massage effect more in line with the actual effect of finger pushing and pressing, so that the user can obtain good comfort.

[0046] Specifically, in some embodiments of this application, the elastic connector 28 may be selected from miniature springs, silicone cantilever and spring sheet structures. Of course, there are no restrictions on the specific structure of the elastic connector 28.

[0047] In an optional embodiment, the electrical stimulation device 4 is provided with an electrical connection portion (not shown in the figure) adapted to the first comb tooth 21 and / or the second comb tooth 22, and a limiting member 29 is provided in the circumferential direction of the elastic connector 28, the limiting member 29 extending along the extension and retraction direction of the elastic connector 28.

[0048] Specifically, in some embodiments of this application, the electrical connection part can be made of a structure such as a pin spring, a conductive sheet, a metal solder joint, or conductive silicone. Of course, there is no limitation on the specific structure of the electrical connection part. Correspondingly, corresponding connection structures can also be provided on the first comb tooth 21 and the second comb tooth 22.

[0049] For example, the limiting member 29 can be selected as a guide rib, a D-shaped cross-section structure, or a ring-shaped structure.

[0050] Understandably, the elastic connector 28 is provided with a limiting member 29 in the circumferential direction, and the limiting member 29 extends along the extension and retraction direction of the elastic connector 28, so that the first comb tooth 21 and the second comb tooth 22 only retain the axial reciprocating degree of freedom. When the first comb tooth 21 and the second comb tooth 22 move in the second motion mode, they are not easy to deviate, which can ensure the stable connection between the first comb tooth 21, the second comb tooth 22 and the electrical connection part to a certain extent.

[0051] In an optional embodiment, combined with Figure 5 and Figure 6 As shown, the first comb teeth 21 are arranged linearly on the comb tooth base 24, and the second comb teeth 22 are arranged around the first comb teeth 21; The first comb tooth 21 has an elliptical cross-section, and the second comb tooth 22 has a star-shaped cross-section.

[0052] Specifically, in some embodiments of this application, four first comb teeth 21 and twelve second comb teeth 22 are provided. The first comb teeth 21 are arranged along a straight line, and the second comb teeth 22 are arranged along an elliptical line and surround the first comb teeth 21.

[0053] Understandably, the second comb tooth 22 is arranged around the first comb tooth 21, constructing a three-dimensional electric field that extends from a point to a surface and surrounds the center, allowing the current to penetrate deeper and be distributed more evenly, effectively enhancing the effect of deep neuromuscular electrical stimulation. The first comb tooth 21 has an elliptical cross-section. The major axis of the elliptical cross-section increases the contact area with the scalp. When the comb assembly 2 oscillates back and forth, the minor axis reduces the resistance of the first comb tooth 21 embedding into the hair, making it easier for the first comb tooth 21 to penetrate the hair and contact the scalp. The second comb tooth 22 has a star-shaped cross-section with multiple protruding parts, providing a tactile sensation similar to knuckle tapping. The difference in shape between the first comb tooth 21 and the second comb tooth 22 further enhances the layered feel of the massage comb during physical massage.

[0054] In an optional embodiment, the first comb tooth 21 and the second comb tooth 22 are tapered away from the comb tooth base 24.

[0055] Understandably, the outer diameters of the first comb tooth 21 and the second comb tooth 22 are gradually reduced in the direction away from the comb tooth base 24, so that the first comb tooth 21 and the second comb tooth 22 have good guiding ability. When the combing head assembly 2 reciprocates, the relatively fine tooth tips can better separate the hair strands, while the cross-section that gradually increases in the direction away from the tooth tips can naturally spread the hair to both sides to optimize the hair combing effect of the massage comb.

[0056] In an optional embodiment, combined with Figure 1 , Figure 3 and Figure 7 As shown, the massage comb also includes: an assembly base 6; The assembly base 6 is set inside the comb handle body 1, the drive device 3 is assembled on the assembly base 6, and the assembly base 6 is also provided with a clearance hole 61. The extension shaft 25 passes through the clearance hole 61 to connect the comb tooth base 24 and the connecting seat 23. The mounting base 6 is provided with a guide shaft 62 extending along the movement direction of the comb assembly 2. A guide wheel 26 is sleeved on the extension shaft 25. The guide wheel 26 has a guide groove 261 that matches the shape of the guide shaft 62. The guide groove 261 extends along the circumferential direction of the guide wheel 26.

[0057] Understandably, the assembly base 6 is set inside the comb handle body 1, and the drive device 3, guide shaft 62, and clearance hole 61 are integrated on the assembly base 6, which simplifies the assembly process of the massage comb components, keeps the drive device 3 and the corresponding transmission chain in a stable relative position, and reduces the possibility of the comb head assembly 2 swaying.

[0058] The extension shaft 25 passes through the relief hole 61 to connect the comb base 24 and the connecting seat 23, so that the comb base 24 and the first comb tooth 21 and the second comb tooth 22 provided on the comb base 24 are located outside the comb handle body 1, which reduces the interference to the movement of the comb head assembly 2 and facilitates the assembly of the comb head assembly 2.

[0059] The mounting base 6 is provided with a guide shaft 62 extending along the movement direction of the comb assembly 2, and a guide wheel 26 is sleeved on the extension shaft 25. The guide wheel 26 has a guide groove 261. The guide shaft 62 can cooperate with the guide wheel 26 to guide the movement of the comb assembly 2, enhance the stability of the comb assembly 2's movement, and adapt to the user's combing actions. Furthermore, the guide wheel 26 can be rotatably mounted on the extension shaft 25, so that the guide wheel 26 and the guide shaft 62 form rolling friction, reducing the movement resistance of the comb assembly 2 and improving the smoothness of the comb assembly 2's movement.

[0060] In an optional embodiment, combined with Figure 3 , Figure 4 and Figure 7 As shown, the extension shaft 25 is also provided with a seal 27 that matches the shape of the relief hole 61; The seal 27 covers the relief hole 61 and is tapered in the direction close to the connector 23, while the diameter of the relief hole 61 is tapered in the direction away from the connector 23.

[0061] Specifically, in some embodiments of this application, the relief hole 61 is circular or approximately circular in shape, and the shape of the seal 27 matches the shape of the relief hole 61.

[0062] Understandably, the seal 27 is located between the extension shaft 25 and the clearance hole 61. On the one hand, the seal 27 covers the clearance hole 61, preventing hair debris and sebum from easily entering the massage comb through the clearance hole 61, and also serves to waterproof and protect the internal circuit structure of the massage comb. On the other hand, the seal 27 has a certain degree of elasticity, which can absorb the impact force from the radial direction of the extension shaft 25, adapting to the reciprocating motion requirements of the comb assembly 2, thereby extending the service life of the massage comb. The clearance hole 61 is gradually tapered away from the connecting seat 23, and the seal 27 is gradually tapered towards the connecting seat 23, which also improves the fit between the clearance hole 61 and the seal 27. The clearance hole 61 and the seal 27 remain stable, and the seal 27 is not easy to detach when it absorbs external force deformation. The sealing function of the seal 27 can be stably realized, meeting the usage requirements of the first massage mode of the comb assembly 2.

[0063] In an optional embodiment, combined with Figure 3 and Figure 7 As shown, at least two guide shafts 62 are provided on the assembly base 6, and a plurality of fixing parts 63 are provided along the length direction of the guide shafts 62; The guide wheel 26 is located within the area enclosed by the guide shaft 62.

[0064] Understandably, at least two guide shafts 62 are symmetrically arranged to form a constrained area on the mounting base 6, within which all guide wheels 26 are located. On one hand, the guide shafts 62 can contact different guide wheels 26 from at least both sides and provide a certain clamping effect on the comb assembly 2 as a whole, enhancing the stability of the comb assembly 2's movement. On the other hand, the arrangement of the guide wheels 26 within the guide shaft 62 area, compared to a design where they are located externally, concentrates the lateral space that needs to expand outward onto the central axis of the comb handle body 1, helping to reduce space occupation and achieve a compact design. Furthermore, the presence of several fixing parts 63 along the length of the guide shaft 62 can also enhance the stability of the connection between the guide shaft 62 and the mounting base 6, making the guide shaft 62 less prone to loosening.

[0065] In an optional embodiment, combined with Figure 1 , Figure 3 and Figure 8 As shown, the drive device 3 includes a power component 31, an eccentric wheel structure 32, and a transmission rod 33; The eccentric wheel structure 32 is mounted on the output shaft of the power component 31. One end of the transmission rod 33 is movably connected to the eccentric wheel structure 32 and is offset from the axis of the output shaft of the power component 31. The other end of the transmission rod 33 is connected to the comb assembly 2 to convert the rotational motion of the power component 31 into the reciprocating motion of the comb assembly 2.

[0066] Specifically, in some embodiments of this application, the power component 31 is a stepper motor. Of course, there are no restrictions on the specific implementation structure of the power component 31.

[0067] Understandably, the transmission rod 33 establishes a rigid connection between the power component 31 and the comb assembly 2. When the power component 31 drives the eccentric wheel structure 32 to rotate, the transmission rod 33 swings back and forth with the eccentric wheel structure 32 to drive the comb assembly 2 to reciprocate back and forth, thereby enabling the first comb tooth 21 and the second comb tooth 22 located on the comb assembly 2 to perform the first type of movement. The overall power output and transmission process is relatively smooth, and the inertial impact is smaller, so as to simulate the effect of real hand massage and enable users to obtain good comfort when using the massage comb. Furthermore, the drive unit 3 operates with low noise, which is suitable for the quiet requirements of the massage comb; the eccentric wheel structure 32, the transmission rod 33 and the comb head assembly 2 are arranged in a straight or near-straight line, which can also eliminate the need for multi-stage gears and help to further realize the compact layout of the massage comb.

[0068] The embodiments of this application have at least the following beneficial effects: This application provides a massage comb with at least two massage modes, which effectively combines different massage modes to meet the diverse head care needs of users. Specifically, the driving device 3 drives the comb assembly 2 to reciprocate relative to the comb handle body 1 in a preset direction, so that the comb assembly 2 has a first massage mode of physical kneading. The electrical stimulation device 4 is used to electrically connect to the comb assembly 2, so that when the comb handle body 1 is held by the user and the comb assembly 2 contacts the user's head, a current circuit is formed, enabling the comb assembly 2 to have a second microcurrent stimulation massage mode. The first massage mode and the second massage mode complement each other and are suitable for the user's personalized and diverse head care needs.
