Description

Technical Field

[0002] As a hair styling tool, combs are only used for combing hair. To enrich the functions of combs, manufacturers have combined low-frequency pulse technology with the traditional comb shape to create portable care tools, such as EMS massage combs. This allows combs to not only comb hair but also massage and relax the face and head.

[0003] In existing EMS massage combs, multiple sets of positive and negative electrodes composed of several conductive posts are typically used as comb teeth to form an electric current circuit when the comb teeth come into contact with the human body, thus achieving a massage effect. When using a massage comb, a certain amount of pressure needs to be applied to ensure good contact between the comb teeth and the body, allowing the ends of the comb teeth to make close contact. However, in existing technologies, the ends of the comb teeth are flat, but the human body surface is not flat; it has natural curvature and bone undulations. This can cause excessive localized pressure and discomfort when applying pressure during use of the massage comb.

[0004] Therefore, existing technologies still need to be improved and enhanced. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0026] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0027] As a hair styling tool, combs are only used for combing hair. To enrich the functions of combs, manufacturers have combined low-frequency pulse technology with the traditional comb shape to create portable EMS massage combs with care functions. This allows the comb to not only comb hair but also massage and relax the face and head.

[0028] EMS massage combs typically feature multiple pairs of positive and negative electrodes composed of conductive posts as comb teeth. This creates a current circuit when the comb teeth contact the body, achieving a massage effect. When using a massage comb, a certain amount of pressure needs to be applied to ensure good contact between the comb teeth and the body. However, in existing technologies, the ends of several comb teeth are flat. Since the human body surface is not flat but has natural curves and bone undulations, applying pressure during use can cause excessive localized pressure, resulting in discomfort. Furthermore, although some traditional combs have curved ends, they cannot achieve EMS massage functionality, resulting in limited functionality and failing to meet user needs.

[0029] In view of the shortcomings of the prior art, this application provides a massage comb, please refer to [link / reference]. Figures 1-4 It includes: a housing 1 and a massage head, the massage head comprising: The assembly comprises a mounting plate 21, a fixing plate 22, a circuit board 23, and a plurality of conductive posts 24; the fixing plate 22 is located between the mounting plate 21 and the circuit board 23; the plurality of conductive posts 24 are of the same specifications and have mounting portions 241 on their outer periphery. The fixing plate 22 and / or the mounting plate 21 are provided with at least some stepped portions 31 of different heights. The fixing plate 22 is fixedly connected to the mounting plate 21 to limit the mounting portion 241 between the fixing plate 22 and the mounting plate 21 and to make at least one end face of the mounting portion 241 contact the stepped portion 31. The ends of the stepped portion 31 are arc-shaped so that the ends of the conductive post 24 extending out of the housing 1 are arc-shaped. The other end of the conductive post 24 passes through the fixing plate 22 and is electrically connected to the circuit board 23.

[0030] This application provides at least some stepped portions 31 of varying heights on the fixed plate 22 and / or mounting plate 21, so that the ends of the conductive posts 24 are distributed in an arc shape when extending out of the housing 1. During use, the massage comb can closely fit the ends of the conductive posts 24 with the human body without requiring much pressure, improving user comfort. At the same time, one end of the conductive post 24 extends out of the housing 1 for human contact, and the other end of the conductive post 24 is electrically connected to the circuit board 23. The user can realize the EMS massage function through the massage comb. The arc-shaped distribution of the ends of the conductive posts 24 ensures the uniformity and stability of the EMS massage effect, enhancing the user experience.

[0031] Furthermore, this application uses several conductive posts 24 of the same specification as the comb teeth of the massage comb. The same specification of the several conductive posts 24 refers to the same length, shape, diameter, and position of the mounting part 241 of the conductive posts 24. Compared with the solution of using conductive posts 24 of different lengths to achieve an arc-shaped distribution at the ends of the conductive posts 24, the advantages of this application are: the conductive posts 24 of the same specification can achieve standardized production, without the need to design molds and set production parameters separately for different lengths, which can reduce manufacturing costs and production errors and improve material control efficiency; during the assembly of the massage comb, there is no need to screen the length or match the position of the conductive posts 24, and workers can directly install them in batches, reducing sorting and alignment steps and reducing human errors such as product defects caused by incorrect installation of different conductive posts 24. It should be noted that the circuit board in this application is an EMS circuit board, and the massage comb is an EMS massage comb. Several conductive posts 24 are divided into positive conductive posts 24 and negative conductive posts 24, so that the current can form a circuit after passing through the human body, thereby achieving the EMS massage effect. Therefore, the several conductive posts 24 are structurally relatively independently mounted on the mounting plate 21. The principle of EMS massage is existing technology and will not be elaborated further in this application. The housing 1 includes a front housing 11 and a rear cover 12 that engage with each other. The massage head is mounted at the open end of the front housing 11. The inner wall of the rear cover 12 extends to form a locking block 121, and the inner wall of the front housing 11 extends to form a locking portion 11. A receiving space is defined between the locking portion 11 and the front housing 11 to guide the locking block 121 into the locking portion 11 and engage with the locking hole 112 on the locking portion 11.

[0032] In the first embodiment of this application, the fixed plate 22 does not have a step portion 31. The back of the mounting plate 21 extends to form a columnar step portion 31, and at least some of the step portions 31 have different heights. The front end of the conductive post 24 (i.e. the end of the conductive post 24 that contacts the human body) passes through the through hole on the mounting plate 21 and its step portion 31. The front end face of the mounting part 241 (i.e. the end face near the mounting plate 21) contacts the step portion 31 on the mounting plate 21. After the mounting plate 21 is screwed and fixed to the fixed plate 22, the mounting part 241 is limited between the step portion 31 on the mounting plate 21 and the fixed plate 22. The rear end of the conductive post 24 extends out of the through hole on the fixed plate 22 and is electrically connected to the circuit board 23. The rear end face of the mounting part 241 (i.e. the end face near the fixed plate 22) contacts the fixed plate 22. In this structure, the length of the conductive post 24 extending out of the housing 1 is adjusted by the step portion 31 on the mounting plate 21, so that the front end of the conductive post 24 is arc-shaped while extending out of the housing 1.

[0033] In the second embodiment of this application, the mounting plate 21 does not have a step portion 31. The front end face of the fixing plate 22 extends to form a columnar step portion 31, and at least some of the step portions 31 have different heights. The front end of the conductive post 24 (i.e., the end of the conductive post 24 that contacts the human body) passes through the through hole on the mounting plate 21. The front end face of the mounting part 241 (i.e., the end face near the mounting plate 21) contacts the mounting plate 21. After the mounting plate 21 and the fixing plate 22 are screwed together, the mounting part 241 is confined between the step portion 31 on the mounting plate 21 and the fixing plate 22. The rear end of the conductive post 24 extends out of the fixing plate 22 and the through hole on its step portion 31 and is electrically connected to the circuit board 23. The rear end face of the mounting part 241 (i.e., the end face near the fixing plate 22) contacts the step portion 31 on the fixing plate 22. In this structure, the front end of the conductive post 24 is adjusted in the length of the portion extending out of the housing 1 by the step portion 31 on the fixing plate 22, so that the front end of the conductive post 24 is arc-shaped while extending out of the housing 1.

[0034] In the third embodiment of this application, both the fixing plate 22 and the mounting plate 21 are provided with stepped portions 31 on their opposite end faces. The two end faces of the mounting portion 241 contact the stepped portions 31 of the fixing plate 22 and the mounting plate 21, respectively. Specifically, in this embodiment, both the fixing plate 22 and the mounting plate 21 are provided with columnar stepped portions 31. The stepped portion 31 on the fixing plate 22 is integrally formed with the fixing plate 22, and the stepped portion 31 on the mounting plate 21 is integrally formed with the mounting plate 21. The front end of the conductive post 24 (i.e., the end of the conductive post 24 that contacts the human body) passes through the through hole on the mounting plate 21 and its stepped portion 31. The front end face of the mounting portion 241 (i.e., the end face near the mounting plate 21) contacts the stepped portion 31 on the mounting plate 21. After the mounting plate 21 and the fixing plate 22 are screwed together, the mounting portion 241 is... 41 is defined between the step portion 31 on the mounting plate 21 and the step portion 31 on the fixing plate 22. The rear end of the conductive post 24 extends out of the fixing plate 22 and the through hole on its step portion 31 and is electrically connected to the circuit board 23. The rear end face of the mounting part 241 (i.e. the end face near the fixing plate 22) contacts the step portion 31 on the fixing plate 22. In this structure, the length of the conductive post 24 extending out of the housing 1 is adjusted by the step portion 31 on the mounting plate 21 and the step portion 31 on the fixing plate 22, so that the front end of the conductive post 24 is arc-shaped while extending out of the housing 1. During use, the conductive post 24 is subjected to the reaction force of the human body. This force is transmitted to the step 31 through the mounting part 241. Since both ends of the mounting part 241 are in contact with the step 31, the force can be distributed to the fixing plate 22 and the mounting plate 21 through the step 31 on both sides, avoiding deformation of the step 31 on one side due to long-term force concentration, and extending the service life of the product. The other end of the conductive post 24 passes through the fixing plate 22 and its step 31 and is electrically connected to the circuit board 23. The limiting structure of the bidirectional step 31 can ensure the stability of the conductive post 24, reduce the risk of electrical connection failure due to shaking, and ensure the stable operation of the EMS function.

[0035] Furthermore, the housing 1 is arc-shaped, the fixing plate 22 is a flat plate, and the mounting plate 21 is an arc-shaped plate.

[0036] In this embodiment, the housing 1 is designed in an arc shape, which can improve the user's grip experience when using the massage comb; the fixing plate 22 adopts a flat design to facilitate the installation and fixing of the circuit board 23. The circuit board 23 is fastened to the back of the fixing plate 22 by screwing. The circuit board 23 is flat, which facilitates the integration of EMS circuit electronic components and ensures the strength of the circuit board, reducing the manufacturing difficulty of the circuit board; the combination of the arc-shaped housing 1 and the arc-shaped distribution of the ends of the conductive posts 24 when they extend out of the housing 1 reduces fatigue when using the massage comb and can better transmit pressure, avoid excessive local force, and further improve the comfort of using the massage comb. The mounting plate 21 has an arc-shaped design, which can better conform to the contour of the human body. This conformity allows the conductive post 24 to make more stable contact with the human body. On the other hand, for massage therapists, the arc-shaped mounting plate 21 can help guide the conductive post 24 to apply pressure evenly, covering more areas of the human body and reducing massage dead spots. Several support posts 211 are provided on the back side of the mounting plate 21 to form a space between the mounting plate 21 and the fixing plate 22 to accommodate the step part 31 and the mounting part 241. The fixing plate 22 has a limiting post 222 on its opposite side to the mounting plate 21, which is sleeved on the outer periphery of the support post 211. Screws pass through the limiting post 222 and extend into the support post 211 to screw the mounting plate 21 and the fixing plate 22 together. The mounting plate 21 and the fixing plate 22 are fixedly connected by screwing. This not only achieves a stable connection between the mounting plate 21 and the fixing plate 22, but also ensures the stability of the installation of the conductive post 24. The overall structure is more compact and easy to assemble and disassemble.

[0037] Furthermore, a sealing ring 25 is fitted onto the conductive post 24, and the sealing ring 25 is located between the mounting portion 241 and the stepped portion 31 on the mounting plate 21.

[0038] In the third embodiment of this application, the mounting plate 21 extends to form a stepped portion 31 on its back side. The sealing ring 25 is sleeved on the conductive post 24, and the front end of the conductive post 24 is inserted into the through hole on the mounting plate 21 and the stepped portion 31 from the side where the stepped portion 31 is located. The fixing plate 22 and the mounting plate 21 are fixedly connected by screws, which confines the conductive post 24 on the mounting plate 21 and causes the mounting portion 241 and the stepped portion 31 to squeeze the sealing ring 25 from both sides. The sealing ring 25 serves two purposes: firstly, it prevents moisture and dust, avoiding dust, dander, moisture and other impurities from entering the massage comb through the gap between the conductive post 24 and the through hole on the mounting plate 21, maintaining the cleanliness of the massage comb and reducing the possibility of poor contact between the conductive post 24 and the circuit board 23; secondly, it has a buffering and shock-absorbing function. During use, the sealing ring 25 can absorb some of the pressure or friction vibration from the human body, reducing the mechanical stress on the connection point between the conductive post 24 and the circuit board and extending its service life.

[0039] Furthermore, a conductive spring 32 is provided at the other end of the conductive post 24, and the conductive spring 32 is installed in the mounting hole on the circuit board 23 so that the other end of the conductive post 24 is electrically connected to the circuit board 23.

[0040] In this application, the rear end of the conductive post 24 is electrically connected to the circuit board via a conductive spring 32. The conductive spring 32 not only conducts electricity but also compensates for assembly errors with its expansion and contraction. Even if there is a slight deviation in the installation position of the conductive post 24 and the circuit board 23, the elasticity of the conductive spring 32 can still allow the two to be electrically connected smoothly without the need for strict control of installation accuracy, thus reducing the difficulty of production and assembly.

[0041] The fixing plate 22 is provided with a positioning post 221, and the circuit board is provided with a positioning hole 231 that mates with the positioning post 221. The positioning post 221 is provided on the back of the fixing plate 22. Through the cooperation of the positioning post 221 and the positioning hole 231, it is ensured that the rear end of the conductive post 24 can contact the conductive spring 32 in the mounting hole on the circuit board 23 while passing through the fixing plate 22, so that the conductive post 24 and the circuit board 23 can be smoothly electrically connected.

[0042] Furthermore, the massage comb also includes a cover plate 4, which is installed in the opening of the housing 1 through a stop structure, and the end face of the cover plate 4 is flush with the end face of the opening of the housing 1.

[0043] In this application, the edge of the cover plate 4 bends and extends towards its back side to form a convex stop. The housing 1 extends towards its inner wall at the opening to form a concave stop that matches the convex stop. The stop structure formed by the cooperation of the convex and concave stops embeds the cover plate 4 into the opening of the housing 1, making the end face of the cover plate 4 flush with the end face of the opening of the housing 1, reducing dust accumulation gaps and improving the aesthetics of the product. The cover plate 4 also acts as a shield for the mounting plate 21, making the end of the massage comb look more aesthetically pleasing and providing dust protection, preventing impurities from directly entering the massage comb from the end face of the mounting plate 21. In addition, the cover plate 4 is provided with through holes corresponding to the mounting plate 21, allowing the front end of the conductive post 24 to pass through and extend out of the housing 1.

[0044] Furthermore, the mounting plate 21 is disposed on the back side of the stop structure, and the mounting plate 21 is fixedly connected to the cover plate 4 to fix the massage head on the housing 1.

[0045] In this application, the cover plate 4 and the mounting plate 21 are located on both sides of the stop structure, and the mounting plate 21 is fixedly connected to the cover plate 4 by screws, so that the cover plate 4 and the massage head are fixed in the opening of the housing 1 with the stop structure as the reference, ensuring the stability of the assembly. Of course, alternatively, a convex stop can be provided on the opening end face of the housing 1, and a concave stop can be provided on the back of the cover plate 4 to cooperate with the convex stop, so that the cover plate 4 is fixed on the opening end face of the housing 1.

[0046] Furthermore, the cover plate 4 is a light-transmitting plate, and the mounting plate 21 is provided with a light-illuminating component 5. Along the light-emitting direction of the light-illuminating component 5, the light-illuminating component 5 and the cover plate 4 define a light-transmitting channel to guide light through the cover plate 4.

[0047] In this application, to further enrich the functions of the massage comb and improve the user experience, a lighting component 5 is provided on the mounting plate 21. The lighting component 5 includes a lamp plate 51 with a light source and a light guide plate 52 for guiding the direction of light emission from the light source. The light guide plate 52 is located between the lamp plate 51 and the mounting plate 21. The lamp plate 51 is connected to the mounting plate 21 by screws to fix the light guide plate 52 on the mounting plate 21. The back of the cover plate 4 extends to form a light guide portion 43, and the mounting plate 21 is provided with a section for the light guide portion 43 to extend into. The slot 212 and the light guide part 43 are connected by a plug-in method, which facilitates the consistency of the assembly of the mounting plate 21 and the cover plate 4. This ensures that the front end of the conductive post 24 passes through the mounting plate 21 and the cover plate 4 simultaneously and extends out of the housing 1. The back of the mounting plate 21 defines an area for placing the light guide plate 52. The light guide plate 52 is mounted on the mounting plate 21, and the light guide holes on the light guide plate 52 can be aligned with the light guide part 43 to form a light transmission channel. This ensures that the light emitted by the light source can evenly and effectively illuminate the target area, thereby improving the lighting effect. In this application, the light source on the lamp plate 51 can be an LED lamp bead or other light source. The light source can emit red light, blue light, yellow light or other colors of light. During the use of the massage comb, the light emitted by the light source passes through the light transmission channel and through the cover plate 4 to irradiate the human body to perform phototherapy and achieve skin care effect. The aforementioned principle and effect of phototherapy are prior art and are not within the protection scope of this application. This application will not elaborate on them here.

[0048] Furthermore, a positioning element 41 is provided on the back of the cover plate 4, and positioning grooves 42 for the positioning element 41 to be inserted are provided on the mounting plate 21 and the light-illuminating component 5. The positioning element 41 is sheet-shaped, and the mounting plate 21 and the light guide plate 52 are provided with waist-shaped positioning grooves 42 that are adapted to the shape of the positioning element 41. The two work together to achieve a stable positioning effect. The aforementioned positioning structure facilitates the rapid assembly of the light guide plate 52, the mounting plate 21, and the cover plate 4. It also allows the light guide holes on the light guide plate 52 to be aligned with the light guide parts 43 on the cover plate 4, ensuring that the light is irradiated to the target area through the light transmission channel.
