Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a massage comb. Background Technology

[0002] With increasing emphasis on scalp care and personal health, massage headbands, as a convenient grooming tool, are gaining popularity among consumers. The market demand for massage headbands is growing, especially for high-end models with features such as electronic muscle stimulation (EMS) and phototherapy. Consumers have higher expectations for the performance, comfort, and durability of these products.

[0003] In existing technologies, the comb teeth of massage combs are typically fixed to the cover plate by compression. While this design ensures a secure installation of the comb teeth, it has certain drawbacks. Because the connection between the comb teeth and the cover plate is achieved through compression, significant pressure is generated during installation. This can lead to cracks appearing in the cover plate during the comb teeth installation process and over long-term use. As the usage time increases, the external forces and pressures on the cover plate gradually increase, causing these cracks to widen further, eventually leading to the cover plate bursting open. This affects the normal use of the massage comb and, in severe cases, can even cause complete product damage. Such defects not only affect the product's aesthetics but also reduce its lifespan.

[0004] Therefore, a massage comb is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a massage comb that solves the problem that the existing comb tooth installation method easily causes cracks in the comb cover, resulting in cracking of the cover and reduced service life.

[0006] To achieve the above-mentioned utility model objectives, this utility model proposes a massage comb, comprising a housing, a cover plate, and metal comb teeth. The cover plate is mounted on the housing and has mounting holes for mounting the metal comb teeth. The metal comb teeth protrude from the cover plate for contacting the scalp to conduct current. The diameter of the metal comb teeth is smaller than the diameter of the mounting holes, and the metal comb teeth have convex rings in the circumferential direction.

[0007] When the metal comb teeth are installed in the mounting hole, the convex ring is interference-fitted with the inner wall of the mounting hole.

[0008] Furthermore, the inner side of the cover plate is provided with an annular groove corresponding to the mounting hole. The annular groove is designed along the circumferential direction of the lower end hole wall of the mounting hole. When the convex ring abuts against the inner wall of the mounting hole, the annular groove makes the lower end hole wall of the mounting hole have an outwardly expanding gap / space.

[0009] Furthermore, the cover plate is provided with a plurality of mounting posts corresponding to the mounting holes, and the mounting posts protrude outward along the central axis.

[0010] Furthermore, it also includes a circuit board located within the housing, the metal comb teeth being electrically connected to the contacts of the circuit board.

[0011] Furthermore, the circuit board has a red LED on the side facing the cover plate, and a light guide plate is provided inside the cover plate, with the light guide plate exposed outside the cover plate and corresponding to the position of the red LED.

[0012] Furthermore, a buffer pad is provided between the cover plate and the light guide plate.

[0013] Furthermore, the metal comb teeth include telescopic teeth and fixed teeth, the telescopic teeth engaging with the fixed teeth, and the telescopic teeth performing telescopic movements relative to the fixed teeth.

[0014] Furthermore, a first receiving cavity is provided inside the fixed tooth, and a first elastic element is provided inside the first receiving cavity, the first elastic element abutting against the telescopic tooth.

[0015] Furthermore, a second receiving cavity is provided inside the fixing tooth, and a second elastic element is provided inside the second receiving cavity. The second elastic element is electrically connected to the circuit board through a conductive element.

[0016] Furthermore, the cover plate is provided with a plurality of mounting posts corresponding to the mounting holes, and the mounting posts protrude outward along the central axis.

[0017] Furthermore, the housing is provided with an identification component for communicating with the identification module in the comb body.

[0018] Beneficial effects:

[0019] This utility model discloses a massage comb, comprising a housing, a cover plate, and metal comb teeth. The cover plate is mounted on the housing and has mounting holes for installing the metal comb teeth. The metal comb teeth protrude from the cover plate for contacting the scalp to conduct current. The diameter of the metal comb teeth is smaller than the diameter of the mounting holes, and a raised ring is provided in the circumferential direction of the metal comb teeth. When the metal comb teeth are installed in the mounting holes, the raised ring is interference-fitted with the inner wall of the mounting holes. In this embodiment, by reducing the diameter of the metal comb teeth to slightly smaller than the diameter of the mounting holes, and by providing a raised ring in the circumferential direction at the lower end of the comb teeth, only the raised ring is in contact with the inner wall of the mounting holes when the metal comb teeth are installed. The lower end contacts and presses against the inner wall of the mounting hole, thus avoiding the other parts of the comb teeth from being squeezed against the inner wall of the mounting hole. This prevents the metal comb teeth from generating excessive pressure during installation. Only the convex ring part contacts the hole wall and is squeezed and fixed during installation. There is a certain distance between the other parts of the metal comb teeth and the inner wall of the mounting hole, so they are not subjected to excessive pressure. This effectively avoids stress concentration. Since the stress is no longer concentrated at the installation part, the risk of cracking of the cover plate during use is greatly reduced, and the overall structure is more stable. This design significantly reduces the possibility of cracking of the cover plate, thereby improving the service life of the massage comb. Attached Figure Description

[0045] Reference Figures 1 to 10 This utility model discloses a massage comb, comprising a housing 100, a cover plate 200, and metal comb teeth 300. The cover plate 200 is mounted on the housing 100 and has mounting holes 210 for mounting the metal comb teeth 300. The metal comb teeth 300 protrude from the cover plate 200 and are used to conduct current in contact with the scalp. The diameter of the metal comb teeth 300 is smaller than the diameter of the mounting holes 210, and the metal comb teeth 300 have a convex ring 900 in the circumferential direction.

[0046] When the metal comb teeth 300 are installed in the mounting hole 210, the convex ring 900 is in an interference fit with the inner wall of the mounting hole 210.

[0047] In this embodiment, reference is made to Figure 4This is a partially enlarged view of the connection between the convex ring 900 and the mounting hole 210. The maximum diameter of the metal comb teeth 300 is smaller than the diameter of the mounting hole 210, and the convex ring 900 is designed in the circumferential direction. During installation, the convex ring 900 contacts the lower end of the inner wall of the mounting hole 210 by pressing. This design avoids the traditional method of fixing by extrusion, reducing the risk of cracking and damage to the cover plate 200. When the metal comb teeth 300 are installed in the mounting hole 210 of the cover plate 200, the pressing of the convex ring 900 with the lower end of the inner wall of the mounting hole 210 provides an effective fixing force. This method ensures that the comb teeth are securely connected to the cover plate 200. In this embodiment, the maximum diameter of the metal comb teeth 300 is slightly smaller than the diameter of the mounting hole 210. Therefore, during the installation of the metal comb teeth 300, there is a gap between the other parts of the metal comb teeth 300, except for the convex ring 900, and the inner wall of the mounting hole 210, which reduces the compression between the metal comb teeth 300 and the cover plate 200 and reduces cracks or damage caused by stress concentration.

[0048] Furthermore, in this embodiment, the actual internal light guide plate 600 is also interference-fitted with the metal comb teeth 300. Through this design, the interference fit between the light guide plate 600 and the metal comb teeth 300 avoids cracking problems caused by interference, and also ensures the stability of the installation. This design can ensure the stable installation of the metal comb teeth and will not affect the appearance or function due to interference. Even if cracks occur in some extreme cases, these cracks occur in the internal structure and will not affect the appearance or performance, ensuring the long-term stability and aesthetics of the product.

[0049] Metal comb teeth 300 protrude from the cover plate 200 to conduct current when in contact with the scalp. This design ensures that the metal comb teeth 300 can achieve good current conduction performance during contact with the scalp, thereby achieving the function of massaging the scalp. The design of this embodiment effectively avoids the problem of cracks in the cover plate 200 and reduced service life caused by the traditional installation method of squeezing the entire comb teeth with the cover plate 200 to achieve fixation. By making the maximum diameter of the metal comb teeth 300 slightly smaller than the aperture and designing a convex ring 900 at the lower end of the metal comb teeth 300, the external force during use can be better dispersed and transmitted, reducing the possibility of cracks in the cover plate 200 during the installation of the metal comb teeth 300 and during use, thereby extending the service life of the cover plate 200 and the metal comb teeth 300.

[0050] The inner side of the cover plate 200 is provided with an annular groove 220 corresponding to the mounting hole 210. The annular groove 220 is designed along the circumferential direction of the lower end hole wall of the mounting hole 210. When the convex ring 900 abuts against the inner wall of the mounting hole 210, the annular groove 220 makes the lower end hole wall of the mounting hole 210 have an outwardly expanding gap / space.

[0051] The cover plate 200 is provided with a plurality of mounting posts 230 corresponding to the mounting holes 210, and the mounting posts 230 protrude outward along the central axis.

[0052] Based on the above embodiments, an annular groove 220 is designed on the lower end face of the cover plate 200. The annular groove 220 is located in the circumferential direction at the connection between the metal comb teeth 300 and the lower end face of the cover plate 200. The design of the annular groove 220 reduces the stress distribution at the connection between the metal comb teeth 300 and the cover plate 200. By setting the annular groove 220 in the circumferential direction at the connection, stress concentration can be effectively reduced, and pressure can be avoided from being directly concentrated on the contact surface between the metal comb teeth 300 and the cover plate 200. The annular groove 220 is equivalent to a stress dispersion zone. This design enhances the compressive strength of the connection area and reduces the risk of the cover plate 200 breaking or cracking due to excessive local stress. During operation, when external force is applied to the metal comb teeth 300, the contact surface between the convex ring 900 on the metal comb teeth 300 and the cover plate 200 will be subjected to compressive force. Through the design of the annular groove 220, these pressures will not be concentrated in a small area, but will be dispersed throughout the circumference of the groove. The annular groove 220 provides a buffer zone through its special geometry (typically a groove), resulting in a more uniform pressure distribution. The cover plate 200 maintains better pressure resistance and durability when subjected to external pressure and impact, extending the overall lifespan of the massage comb. Furthermore, by reducing microcracks caused by stress concentration, the long-term reliability of the massage comb is improved, reducing maintenance costs and replacement frequency, and enhancing the overall durability of the massage comb.

[0053] In addition, an outwardly curved mounting post 230 is provided at the connection between the upper end face of the cover plate 200 and the metal comb teeth 300. The mounting post 230 protrudes outward along the central axis. This design improves installation stability and enhances the durability of the cover plate 200 compared to the original inwardly recessed mounting post 230 structure. The outwardly protruding design changes the stress distribution, making the stress on the cover plate 200 more uniform during installation, avoiding the stress concentration problem caused by the concave shape in the traditional design, thereby reducing the risk of cracking of the cover plate 200. During installation, the outwardly protruding mounting post 230 effectively reduces the problem of excessive local stress, avoiding excessive compression or tension concentration caused by the concave post in the traditional design. The outwardly protruding shape not only prevents cracks in the cover plate 200 due to stress concentration, but also ensures a tight connection between components during use, thereby improving the overall structural stability.

[0054] The massage comb also includes a circuit board 400 located inside the housing 100, and the metal comb teeth 300 are electrically connected to the contacts of the circuit board;

[0055] The circuit board 400 has a red LED 700 on the side facing the cover plate 200, and a light guide plate 600 is provided inside the cover plate 200. The light guide plate 600 is exposed outside the cover plate 200 and corresponds to the position of the red LED 700.

[0056] The housing 100 is provided with an identification element 110.

[0057] In this embodiment, the circuit board 400 is electrically connected to the metal comb teeth 300 via conductive elements (i.e., contacts). When the massage comb is installed on the comb body, the user uses the hair-strengthening comb, and the metal comb teeth 300 contact the scalp, thereby conducting microcurrents to the scalp to achieve an EMS (electronic muscle stimulation) massage effect. A red LED 700 is provided on the side of the circuit board 400 facing the scalp, which can provide a phototherapy effect, promote scalp blood circulation, and enhance scalp health. A light guide plate 600 is provided on the side of the housing 100 facing the scalp. The light guide plate 600 protrudes from the cover plate 200 and corresponds to the position of the red LED 700. The light guide plate 600 is used to evenly disperse the light emitted by the red LED 700 to cover a wider area of ​​the scalp. The identification component is usually an RFID or NFC tag used to communicate with the identification module in the comb body so that the comb body can identify the massage comb and activate the corresponding massage function. Through the identification component 110, the comb body can automatically identify the type of massage comb and start the corresponding care program, simplifying user operation. The intelligent identification and control of the working status of the massage comb improves the convenience and comfort of use, and users do not need to manually switch settings.

[0058] The housing 100 is provided with a foolproof part 120. This design ensures that the functional head can be correctly installed into the comb body, avoiding poor contact or reverse connection between the functional head and the identification module on the comb body, thereby ensuring that the identification module can accurately control the working state of the functional head.

[0059] A buffer pad 800 is provided between the cover plate 200 and the light guide plate 600.

[0060] In this embodiment, the buffer pad 800 is designed to provide cushioning for the cover plate 200 and light guide plate 600 during the installation of the metal comb teeth 300, thereby preventing direct contact and damage between the cover plate 200 and light guide plate 600 due to mechanical pressure or external forces during installation. The buffer pad 800 effectively reduces and disperses the pressure applied during the installation of the metal comb teeth 300. When the metal comb teeth 300 are installed in place, a certain amount of compressive force is generated during the installation process. Without the buffer pad 800, the cover plate 200 and light guide plate 600 may be subjected to certain pressure, leading to friction, deformation, or damage between them. By providing a soft buffer layer, the buffer pad 800 can absorb and disperse this pressure. The design of the buffer pad 800 effectively protects the cover plate 200 and light guide plate 600 during the installation of the metal comb teeth 300, avoiding damage caused by pressure and stress concentration during installation. This design not only improves the durability of the components and extends the product's lifespan, but also ensures that the massage comb maintains good performance and stability during use.

[0061] The metal comb teeth 300 include telescopic teeth 310 and fixed teeth 320. The telescopic teeth 310 are engaged with the fixed teeth 320, and the telescopic teeth 310 can extend and retract relative to the fixed teeth 320.

[0062] The fixed tooth 320 has a first receiving cavity 330, and the first receiving cavity 330 has a first elastic element 350. The first elastic element 350 abuts against the telescopic tooth 310 and is used to provide longitudinal force to the telescopic tooth 310.

[0063] In this embodiment, the telescopic teeth 310 and the fixed teeth 320 are connected by a snap-fit ​​mechanism, allowing the telescopic teeth 310 to move longitudinally within a certain range. The fixed teeth 320 have a first receiving cavity 330, where an elastic element contacts the telescopic teeth 310. The elastic element provides a force along the longitudinal axis to the telescopic teeth 310, enabling them to maintain appropriate elasticity and telescopicity. This telescopic comb design allows for adjustment of the telescopic range according to the scalp's curve and combing force, reducing discomfort caused by hard contact between the comb teeth and reducing pressure damage to the scalp, making it more suitable for prolonged use. The telescopic comb teeth provide cushioning during combing, enhancing comfort. Simultaneously, the telescopic nature of the comb teeth in contact with the scalp creates a better massage effect, promoting blood circulation and achieving a soothing and massaging effect, making it particularly suitable for functions such as electronic muscle stimulation (EMS).

[0064] The fixing tooth 320 also has a second receiving cavity 340, and the second receiving cavity 340 has a second elastic member 360. The second elastic member 360 is electrically connected to the circuit board 400 through a conductive member for conducting electricity.

[0065] In this embodiment, the fixed teeth 320 have a first receiving cavity 330 and a second receiving cavity 340, which are separated by a tooth plate to form two spaces. The second receiving cavity 340 is provided with a second elastic element 360. The purpose of the second elastic element 360 is to conduct electricity and realize the conduction of current. One end of the second elastic element 360 abuts against the tooth plate, and the other end is electrically connected to the circuit board 400 through a conductive element, thereby realizing the efficient conduction of current. This allows the metal comb teeth 300 to achieve a massage effect by contacting the scalp during use. Through the conduction of the metal comb teeth 300, the current finally reaches the scalp and achieves the expected massage effect, such as electronic muscle stimulation (EMS) or other types of scalp massage, thereby promoting scalp blood circulation and health.

[0066] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
