Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a waterproof structure for a massage comb. Background Technology

[0002] In the field of hair care, massage combs, as tools that combine the functions of combing hair and massaging the head, are often used in humid environments and can accumulate dirt from the hair after prolonged use. Therefore, regular cleaning has become an essential part of using massage combs.

[0003] Water washing is a convenient and effective cleaning method that can meet users' requirements for tool cleanliness. To prevent water from corroding the internal structure of the massage comb during the washing process, existing technologies usually use an independent sealing ring on each comb tooth to prevent water from seeping into the massage comb along the periphery of the comb tooth. The drawback is that the sealing rings need to be removed, fitted, and positioned one by one during the assembly process, which is cumbersome and inefficient.

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

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a waterproof structure for a massage comb, which aims to solve the problem of inconvenient assembly of the waterproof structure of the massage comb in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A first waterproof component is located inside the comb body. A first rib is provided on the end face of the first waterproof component, and the first rib is coaxially arranged with the guide hole.

[0011] The front end of the comb teeth passes through the first waterproof component and the guide hole and extends out of the comb body. The first rib is sleeved on the outer periphery of the comb teeth. The outer periphery of the first rib contacts the inner wall of the guide hole. When the first waterproof component is pressed, the first rib is squeezed and deformed between the comb teeth and the guide hole to seal the gap between the guide hole and the comb teeth.

[0012] The comb body is also provided with a circuit board, and the rear end of the comb teeth is inserted into the circuit board. The circuit board is fixedly connected to the end of the comb body, so that the first waterproof component is under pressure.

[0013] The outer periphery of the comb teeth extends radially to form an abutment portion, which is located between the first waterproof component and the circuit board. The circuit board is fixedly connected to the end of the comb body and the first waterproof component is pressed through the abutment portion to compress and deform the first rib between the comb teeth and the guide hole. The first rib seals the gap between the guide hole and the comb teeth.

[0014] The end of the comb extends inward to form a guide post coaxially arranged with the guide hole.

[0015] The outer peripheral surface of the first rib is an arc surface. The guide post has a first sealing surface on its inner wall near its end that is adapted to the outer peripheral surface of the first rib. When the first waterproof component is under pressure, the outer peripheral surface of the first rib abuts against the first sealing surface.

[0016] The first waterproof component has a stepped portion, and the abutting portion is located on the outer periphery of the stepped portion, with the end of the guide post abutting against the stepped portion.

[0017] The comb body is also provided with a light guide and a second waterproof component. The light guide is provided with a plurality of light guide portions. The end of the light guide portion passes through the second waterproof component and extends out of the comb body or extends to the end of the comb body. The light guide is fixedly connected to the end of the comb body, so that the second waterproof component is subjected to pressure.

[0018] The second waterproof component has a second rib on the end face away from the end of the comb body, and the light guide component has a boss located on the outer periphery of the light guide portion.

[0019] The second waterproof component is also provided with a third rib, which is disposed back to back on the end face of the second waterproof component.

[0020] The end of the comb body is provided with a second sealing surface that matches the third rib.

[0021] Compared to existing technologies, the present invention provides a waterproof structure for a massage comb, comprising:

[0022] The comb body has a guide hole at its end.

[0023] A plurality of comb teeth, wherein the comb teeth are installed in the guide hole;

[0024] A first waterproof component is located inside the comb body. A first rib is provided on the end face of the first waterproof component, and the first rib is coaxially arranged with the guide hole.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] In the field of hair care, massage combs, as tools that combine the functions of combing hair and massaging the head, necessitate water washing due to their usage scenarios and cleaning needs.

[0041] From a usage perspective, users often apply massage combs in humid environments during hair care routines. For example, during shampooing, using a massage comb with shampoo or conditioner can promote the penetration of cleansing ingredients through the pressure of the comb teeth on the scalp, while reducing the pulling damage when combing wet hair. In the application of conditioner, hair masks, and other hair care products, the massage comb helps the product distribute evenly across the hair strands and enhances the scalp's absorption of nutrients through massage. These humid usage scenarios inevitably lead to moisture and product residue coming into contact with the surface of the massage comb and the gaps between the comb teeth. If it cannot be directly washed with water, it will be difficult to maintain the cleanliness of the tool.

[0042] From a cleaning and maintenance perspective, massage combs inevitably accumulate oil, dandruff, dust, and styling product residue (such as hair wax and hairspray) when used in dry environments. If these residues remain between the comb teeth or on the comb's surface for a long time, they can not only breed bacteria and produce odors, but may also secondary contaminate the scalp during subsequent use, leading to scalp sensitivity and clogged hair follicles. Especially for models with densely packed teeth or massage protrusions, the dirt in the crevices is difficult to remove completely by dry wiping. Washing, however, utilizes the rinsing force of water to effectively remove residual impurities, ensuring the hygienic performance of the massage comb.

[0043] Furthermore, as consumers raise their hygiene standards for personal care tools, regular deep cleaning has become an essential step in using massage combs. Washing with water, as a convenient and effective cleaning method, meets users' requirements for tool cleanliness, ensuring its safety and comfort during long-term use. Therefore, washing massage combs is a routine procedure based on actual usage scenarios and hygiene needs, and is also an important guarantee for improving the product's user experience.

[0044] To prevent water from corroding the internal structure of the massage comb during washing, existing technologies typically use an independent sealing ring on each comb tooth to prevent water from seeping into the comb along the periphery of the teeth. However, this method has drawbacks: the sealing rings require repeated operations such as removing, fitting, and positioning each one individually during assembly, making the process cumbersome and inefficient. Furthermore, uneven pressure during manual fitting can lead to twisting or improper installation of the sealing rings, increasing the risk of seal failure. If a sealing ring on a comb tooth is not properly fitted (e.g., missing or damaged), the comb body needs to be disassembled for replacement. However, the dense arrangement of the comb teeth during disassembly may cause other sealing rings to fall off or be damaged, leading to secondary problems.

[0045] In view of the shortcomings of the prior art, this utility model provides a waterproof structure for a massage comb, comprising:

[0046] Comb body 1, wherein a guide hole 11 is provided at the end of the comb body 1;

[0047] A plurality of comb teeth 2 are installed in the guide hole 11;

[0048] The first waterproof component 3 is located inside the comb body 1. A first protruding rib 31 is provided on the end face of the first waterproof component 3, and the first protruding rib 31 is coaxially arranged with the guide hole 11.

[0049] The front end of the comb teeth 2 passes through the first waterproof component 3 and the guide hole 11 and extends out of the comb body 1. The first rib 31 is sleeved on the outer periphery of the comb teeth 2, and the outer peripheral surface of the first rib 31 contacts the inner wall of the guide hole 11. When the first waterproof component 3 is pressed, the first rib 31 is squeezed and deformed between the comb teeth 2 and the guide hole 11 to seal the gap between the guide hole 11 and the comb teeth 2. In this application, by providing the first rib 31 on the first waterproof component 3, the first rib 31 sleeved on the outer periphery of several comb teeth 2 can be squeezed and deformed when the first waterproof component 3 is pressed, thereby sealing the gap between the comb teeth 2 and their corresponding guide holes 11. The structure is simple, the assembly is convenient, and the assembly efficiency of the massage comb is improved. It should be noted that in this application, the side where the comb teeth 2 protrude is the front, and the opposite side is the back or reverse side. This application uses this as a directional reference to describe the waterproof structure of the massage comb.

[0050] Furthermore, a circuit board 4 is also provided inside the comb body 1. The rear end of the comb teeth 2 is inserted into the circuit board 4 and electrically connected to the circuit board 4. The circuit board 4 is fixedly connected to the end of the comb body 1, so that the first waterproof component 3 is under pressure.

[0051] In this embodiment, the first waterproof component 3 is located between the end of the circuit board 4 and the comb body 1. The end of the comb body 1 extends inward to form a first fixing post 12. The end of the first fixing post 12 passes through the first waterproof component 3 and contacts the surface of the circuit board 4. The screw passes through the through hole on the circuit board 4 and extends into the first fixing post 12 to fix the circuit board 4 and the end of the comb body 1. In this embodiment, the circuit board 4 and the end of the comb body 1 are screwed together, which provides a more stable installation of the comb teeth 2 in the guide hole 11. At this time, the outer peripheral surface of the comb teeth 2 and the inner wall of the guide hole 11 exert relative extrusion force on the first protruding rib 31 on the first waterproof component 3 from both sides, causing the first protruding rib 31 to be deformed by extrusion, thereby sealing the gap between the guide hole 11 and the comb teeth 2. Compared with the traditional method of waterproofing the massage comb by using sealing rings fitted on several comb teeth 2, this application has a simple structure, can quickly realize the disassembly and assembly of the waterproof structure, and improves the assembly efficiency of the massage comb.

[0052] Furthermore, the outer periphery of the comb teeth 2 extends radially to form an abutment portion 21, which is located between the first waterproof component 3 and the circuit board 4. The circuit board 4 is fixedly connected to the end of the comb body 1 and the first waterproof component 3 is pressed through the abutment portion 21 to compress and deform the first rib 31 between the comb teeth 2 and the guide hole 11. The first rib 31 seals the gap between the guide hole 11 and the comb teeth 2.

[0053] In this embodiment, the first rib 31 is annular; the abutment portion 21 is annularly disposed on the outer periphery of the comb teeth 2 and is integrally formed with the comb teeth 2. The front end of the comb teeth 2 passes through the back side of the first waterproof component 3 and extends out of the end of the comb body 1 through the guide hole 11. The abutment portion 21 is located on the back side of the first waterproof component 3. When the circuit board 4 is installed on the back side of the first waterproof component 3, the abutment portion 21 is located between the first waterproof component 3 and the circuit board 4. The circuit board 4 is fixedly connected to the end of the comb body 1, which will cause the abutment portion 21 to exert a squeezing force on the first waterproof component 3. On this basis, the first rib 31 will be subjected to squeezing force in the direction of the end face of the first waterproof component 3, further increasing the degree of squeezing deformation of the first rib 31 between the comb teeth 2 and the guide hole 11, thereby improving the sealing effect. In addition, the back side of the first waterproof component 3 is provided with an annular limiting part 33, which is located on the outer periphery of the abutting part 21 to limit the position of the abutting part 21, thereby preventing the position of the comb teeth 2 from shifting during the use of the massage comb and affecting normal use.

[0054] Furthermore, the end of the comb body 1 extends inward to form a guide post 13 coaxially arranged with the guide hole 11, and the guide post 13 is a hollow cylinder; the outer peripheral surface of the first rib 31 is an arc surface, and the guide post 13 has a first sealing surface 14 adapted to the outer peripheral surface of the first rib 31 on its inner wall near its end. When the first waterproof component 3 is under pressure, the outer peripheral surface of the first rib 31 abuts against the first sealing surface 14. In this application, the end of the comb body 1 is the horizontal part where the comb teeth 2 extend out of the comb body 1.

[0055] In this embodiment, when the circuit board 4 is fixedly connected to the end of the comb body 1, the abutment part 21 is located between the first waterproof component 3 and the circuit board 4, causing the abutment part 21 to abut against the back side of the first waterproof component 3. The guide post 13 is provided so that the end of the guide post 13 abuts against the front end face of the first waterproof component 3. The abutment part 21 and the guide post 13 press against the first waterproof component 3 from the front and rear sides in the area near the first rib 31, ensuring the stability of the first waterproof component 3 in the sealing area assembly, increasing the degree of compression deformation of the first rib 31 between the comb teeth 2 and the guide hole 11, and improving the sealing effect. The guide post 13 has a first sealing surface 14 on its inner wall near its end. The first sealing surface 14 and the outer peripheral surface of the first rib 31 are both arc surfaces, so that the first rib 31 deforms along the first sealing surface when pressed, which is beneficial to the tighter fit between the outer peripheral surface of the first rib 31 and the first sealing surface 14, enhancing the sealing effect.

[0056] Furthermore, the first waterproof component 3 is provided with a step portion 32, and the step portion 32 is located on the outer periphery of the first protruding rib 31, and the end of the guide post 13 abuts against the step portion 32.

[0057] In this embodiment, the step portion 32 is annular and located on the front end face of the first waterproof component 3. It is formed by the first rib 31 extending outward along its periphery. The height of the step portion 32 in the thickness direction of the first waterproof component 3 is less than the height of the first rib 31 to avoid the step portion 32 affecting the deformation of the first rib 31 under pressure. The circuit board 4 is fixedly connected to the end of the comb tooth 2. The end face of the step portion 32 is in close contact with the end face of the guide post 13. The outer peripheral surface of the first rib 31 is in close contact with the first sealing surface 14, which increases the contact area between the guide post 13 and the first waterproof component 3, thereby further improving the sealing effect.

[0058] Furthermore, the comb body 1 is also provided with a light guide 5 and a second waterproof component 6. The light guide 5 is provided with a plurality of light guide portions 51. The front end of the light guide portion 51 passes through the second waterproof component 6 and extends out of the comb body 1 or extends to the end of the comb body 1. The light guide 5 is fixedly connected to the end of the comb body 1 so that the second waterproof component 6 is compressed. The second waterproof component 6 is squeezed and deformed to seal the gap between the light guide 5 and the comb body 1.

[0059] In this application, LED beads or other light sources are provided on the circuit board 4. The light guide part 51 is located on the light emission channel of the light source. A light guide channel is provided inside the light guide part 51. One end of the light guide channel is open and faces the light source to guide the illumination path of the light source. The other end of the light guide channel is a blind hole to prevent moisture, dust and other impurities from entering the comb body 1 from the light guide channel. The light guide part 51 is made of a light-transmitting material. In this embodiment, a light guide hole 17 is provided at the end of the comb body 1 so that the end of the light guide part 51 can extend out of the comb body 1 or extend to the end of the comb body 1. There is usually a certain gap between the part of the light guide part 51 inside the light guide hole 17 and the inner wall of the light guide hole 17. In order to prevent moisture, dust and other impurities from entering the comb body 1, a second waterproof part 6 is provided between the light guide part 5 and the end of the comb body 1. The second waterproof part 6 is sleeved on the outer periphery of the light guide part 51. The second waterproof component 6 is fixedly connected and squeezed, causing it to deform under pressure. This ensures that the front end of the second waterproof component 6 is in close contact with the end of the comb body 1, and that the periphery of the light guide 51 is in close contact with the second waterproof component 6. This prevents impurities from entering the comb body 1 through the gap between the light guide hole 17 and the light guide 51. The end of the comb body 1 extends inward to form a second fixing post 15. The end of the second fixing post 15 passes through the second waterproof component 6 and extends into the mounting groove on the light guide 5. One end of the mounting groove has an opening for the second fixing post 15 to be installed. The other end of the mounting groove has an annular support, and the center of the annular support has a threaded hole. A screw passes through the threaded hole and enters the second fixing post 15, so that the light guide 5 is fixedly connected to the end of the comb body 1 and the second waterproof component 6 is pressurized to seal the light guide 5 and the comb body 1. The overall structure is simple and easy to assemble, greatly improving the assembly efficiency of the massage comb.

[0060] Furthermore, the second waterproof component 6 has a second rib 61 on its end face away from the comb body 1, and the light guide component 5 has a boss 52 located on the outer periphery of the light guide portion 51. The second waterproof component 6 also has a third rib 62, which is positioned back-to-back with the second rib 61 on its end face. The end of the comb body 1 has a second sealing surface 16 that matches the third rib 62.

[0061] In this embodiment, the second waterproof component 6 has a second rib 61 on its back end face. The front end of the light guide 51 extends through the through hole of the second waterproof component 6 and out of the comb body 1 or extends to the end of the comb body 1. The third rib 62 is provided on the end face of the second waterproof component 6 near the comb body 1 (i.e., the third rib 62 is provided on the front end face of the second waterproof component 6). The boss 52, the second rib 61 and the third rib 62 are annular, and the surfaces of the second rib 61 and the third rib 62 are arc surfaces. The boss 52 on the light guide 5 is arranged opposite to the second rib 61. The light guide 5 is fixedly connected to the end of the comb body 1. The boss 52 is squeezed by the second rib 61 to press the third rib 62. The second rib 61 is in close contact with the boss 52, and the third rib 62 is in close contact with the end of the comb body 1. At the same time, the periphery of the light guide 51 is in close contact with the second rib 61, the third rib 62 and the inner wall of the through hole of the second waterproof component 6 to achieve a sealing effect. The surfaces of the second rib 61 and the third rib 62 are designed as arc surfaces, so that the contact area of ​​the second rib 61 and the third rib 62 changes from line contact to surface contact during the compression process. Compared with the flat sealing contact, the arc surface can expand the sealing contact area through elastic deformation, transmit pressure more evenly, and reduce the risk of leakage due to poor contact. At the same time, the arc surface can fit more tightly to the mating surface under high pressure and maintain basic sealing performance under low pressure, avoiding the problem of insufficient local pressure that may occur with flat sealing. The corners of the flat surface are subject to stress concentration due to compression, which may cause material cracking after long-term use. The arc surface, through its smooth transition curved surface structure, disperses the stress to a larger area, reduces excessive local stress, and extends the service life of the second waterproof component 6. In addition, the arc surface structure can adapt to deviations in component installation or manufacturing according to its own deformation, avoiding sealing failure due to insufficient installation accuracy. The end of the comb body 1 is recessed on its back side and on the outer periphery of the light guide hole 17 to form a second sealing surface 16. The second sealing surface 16 includes a flat surface on the inner ring and an arc surface on the outer ring. The second sealing surface 16 is designed so that the third rib 62 can deform along the second sealing surface 16 when it is pressed. The inner ring flat surface is designed to provide a stable and high-strength main sealing interface for the component, ensuring that the third rib 62 fits tightly with the end of the comb body 1. The outer ring arc surface is designed to provide elastic compensation and fault tolerance. In the actual assembly process, the arc surface fits with the third rib 62 to fill the gap, and also avoids the third rib 62 from being slightly deformed due to temperature changes, which would affect the sealing effect.

[0062] In this application, raised ribs are provided on the first waterproof component 3 and the second waterproof component 6. The first waterproof component 3 is pressed between the end of the circuit board 4 and the comb body 1, and the second waterproof component 6 is pressed between the end of the light guide 5 and the comb body 1, by means of screw fixing. This allows the raised ribs to deform under pressure and achieve a waterproof seal between the end of the comb teeth 2 and the end of the comb body 1, and between the end of the light guide 5 and the end of the comb body 1. The raised ribs are integrally formed on the first waterproof component 3 and the second waterproof component 6, which facilitates quick assembly and disassembly of the massage comb and improves assembly efficiency. It should be noted that, in order to avoid interference between the structure of the first waterproof component 3 and the second waterproof component 6 during fixing or assembly, the fixing of the light guide 5 to the comb body 1 and the fixing of the circuit board 4 to the comb body 1 are achieved by staggered arrangement inside the comb body 1. The light guide hole 17 and the guide hole 11 are also staggered at the end of the comb body 1. Both the second waterproof component 6 and the light guide 5 are provided with through holes for the comb teeth 2 to pass through. Furthermore, compared to existing technologies that use several independently fitted sealing rings to achieve waterproof sealing, the massage comb achieves waterproof sealing by setting a rib on the waterproof component in an integrated structure. This makes the waterproof component easy to install and remove, and also avoids the problem in traditional structures where manual fitting of the sealing ring is not done properly or uneven force is applied, which can cause the sealing ring to twist and affect the waterproof effect.

[0063] In summary, the waterproof structure of the massage comb provided by this utility model includes:

[0064] The comb body has a guide hole at its end.

[0065] A plurality of comb teeth, wherein the comb teeth are installed in the guide hole;

[0066] A first waterproof component is located inside the comb body. A first rib is provided on the end face of the first waterproof component, and the first rib is coaxially arranged with the guide hole.

[0067] The front end of the comb teeth passes through the first waterproof component and the guide hole and extends out of the comb body. The first rib is sleeved on the outer periphery of the comb teeth. The outer periphery of the first rib contacts the inner wall of the guide hole. When the first waterproof component is pressed, the first rib is squeezed and deformed between the comb teeth and the guide hole to seal the gap between the guide hole and the comb teeth.

[0068] In this application, a first rib is provided on the first waterproof component, so that the first rib sleeved on the outer periphery of several comb teeth can be squeezed and deformed when the first waterproof component is under pressure, thereby sealing the gap between the comb teeth and their corresponding guide holes. The structure is simple, the assembly is convenient, and the assembly efficiency of the massage comb is improved.
