Description

Technical Field

[0001] This application relates to the technical field of hair-growing devices, and particularly to a laser hair-growing device.

Background Art

[0002] A laser hair-growing device is a non-invasive device for hair removal treatment. Its operating principle is to irradiate the scalp with a low-power laser having a specific wavelength, stimulate the activity of hair follicles, improve local blood circulation, and promote hair growth. Many conventional laser hair-growing products adopt a helmet-type or cap-type structure that integrates multiple laser light sources inside the device and irradiates in a way that covers the entire scalp. Such a structure can achieve large-area irradiation, but there are some technical limitations in actual use.

[0003] First, the laser light source of a conventional laser hair-growing device is usually provided at a position 2 - 3 cm from the scalp. The laser reaches the hair follicles only after passing through the hair layer during the propagation process. In addition to the significant blocking and scattering absorption effects of the hair on the laser, due to the long irradiation distance, the laser naturally attenuates, resulting in the laser energy actually reaching the hair follicles being far below the effective treatment threshold, making it difficult to guarantee the treatment effect. Furthermore, many conventional devices adopt a sealed or semi-sealed structure, and since the laser module is integrated inside the housing, heat is difficult to dissipate. When used for a long time, heat easily accumulates locally on the head, causing a stuffy and uncomfortable feeling, which affects the safety and comfort during the continuous use of the device. Next, the structural design of conventional products is generally heavy, especially the overall weight of the helmet-type products is large. During wearing, continuous pressure is applied to the head, not only reducing the comfort of use but also potentially affecting the user's compliance.

[Effects of the Invention]

[0015] The embodiments of this application have the following beneficial effects.

[0016] In this embodiment of the laser hair growth device, the attachment member includes a plurality of spaced-apart comb teeth, the comb teeth extending outward from the connection part, and the laser light panel connected to the comb teeth. The comb teeth are used to guide the light and comb the hair roots when attached.

Mode for Carrying Out the Invention

[0021] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, hereinafter, while referring to the drawings in the embodiments of the present application, the technical solutions of the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, those skilled in the art will understand that all other embodiments obtained without creative work belong to the protection scope of the present application.

[0022] A laser hair growth device is a non-invasive device for hair removal treatment. Its operating principle is to irradiate the scalp with a low-power laser having a specific wavelength, stimulate the activity of hair follicles, improve local blood circulation, and promote hair growth. Many conventional laser hair growth products adopt a helmet-type or cap-type structure that integrates multiple laser light sources inside the device and irradiates in a way that covers the entire scalp. Such a structure can achieve large-area irradiation, but there are some technical limitations in actual use.

[0023] First, the laser light source of conventional laser hair growth devices is usually positioned 2-3 cm from the scalp, and the laser only reaches the hair follicle after passing through the hair layer during propagation. In addition to the significant blocking and scattering absorption effect of hair, the long irradiation distance causes natural attenuation, resulting in the laser energy that actually reaches the hair follicle being significantly below the effective treatment threshold, making it difficult to guarantee treatment effectiveness. Furthermore, many conventional devices employ a sealed or semi-sealed structure, and because the laser module is integrated within the housing, heat dissipation is poor. With prolonged use, heat tends to accumulate locally on the head, causing stuffiness and discomfort, affecting the safety and comfort of continuous use of the device. Secondly, the structural design of conventional products is generally heavy, and the overall weight of helmet-type products in particular is large, which puts continuous pressure on the head during wear, not only reducing comfort of use but also potentially affecting user compliance.

[0024] Based on this, as shown in Figures 1 and 2, an embodiment of the present invention provides a laser hair growth device 10 including an attachment member 100 and a laser light panel 200, the attachment member 100 including a comb portion 110 and a connecting portion 120, the number of comb portions 110 being multiple, each comb portion 110 being connected to the connecting portion 120, the multiple comb portions 110 being spaced apart, the comb portions 110 extending outward from the connecting portion 120, the connecting portion 120 having a transparent structure at least in part, and the laser light panel 200 being connected to the comb portion 110 for guiding light and combing the hair roots. During actual use, the user inserts the comb portion 110 between the hairs, and the comb portion 110 can part the hair so as not to obstruct the laser light path, thereby ensuring that the laser is directly irradiated onto the surface of the scalp and improving the effective utilization rate of the laser energy.

[0025] Specifically, the number of the comb teeth portions 110 may be one, two, or two or more, and is not uniquely limited herein. In a preferred embodiment, the number of the comb teeth portions 110 is 5, 8, 12, or 16, and specifically, it is designed according to the requirements of the scalp coverage range and the laser irradiation density. Providing a plurality of the comb teeth portions 110 not only helps to expand the effective irradiation area, but also enables uniform coverage of different regions of the scalp through a reasonable arrangement, avoiding local irradiation deficiencies and excessive energy concentration. Furthermore, the open structure formed by providing the plurality of comb teeth portions 110 at intervals provides a good air flow path for the laser light panel 200, which is advantageous for the heat generated during the operation of the device to be quickly dissipated by natural convection, suppressing local temperature rises and improving comfort during long-term use.

[0026] In this embodiment, the laser light panel 200 is provided at the bottom or side wall of the comb teeth portion 110. The laser is emitted from the laser light panel 200, propagated through the light guiding passage inside the comb teeth portion 110 to the end or side surface of the comb teeth portion 110, and further irradiated onto the scalp. Since the comb teeth portion 110 directly contacts or is close to the scalp, the distance from the laser light source to the scalp can be shortened to less than 0.5 cm, significantly reducing the natural attenuation of the laser during propagation and the losses due to scattering and absorption in the hair layer. The distance from the laser light source to the scalp is preferably 0.2 cm, 0.3 cm, 0.4 cm, or 0.5 cm, and specifically, it can be adjusted according to the structural dimensions of the comb teeth portion 110 and the fitting feeling during wearing.

[0027] The connector 120 has a transparent structure in at least part of it and can be manufactured from a material such as transparent polycarbonate, acrylic, or silicone with high light transmittance, preferably with a light transmittance of 85% or more. The transparent structure not only supports the mounting of the laser light panel 200 but also functions as an auxiliary light guide and can engage with the comb teeth 110 to achieve uniform output and distribution of the laser. For example, a portion of the laser can be refracted downward or scattered through the transparent area of ​​the connector 120, supplementing the illumination of the scalp area between adjacent comb teeth 110, thereby improving the continuity and uniformity of the overall illumination. Furthermore, the transparent design of the connector 120 also helps the user to intuitively observe the operating status of the device and improve the user experience.

[0028] The material of the comb teeth 110 can be selected from polymer materials having a certain degree of hardness and flexibility, such as polypropylene (PP), thermoplastic elastomer (TPE), or polyoxymethylene (POM). The light guiding function can be achieved by providing a light guide path inside or by adopting an integrated light-transmitting structure. In one specific embodiment, the comb teeth 110 is a solid light-transmitting structure, and its outer surface is polished or microstructured to control the laser emission angle, thereby preventing the beam from becoming excessively concentrated and localized to excessively high energy. In another embodiment, a hollow light-guiding cavity is provided inside the comb teeth 110, and the laser emitted from the laser light panel 200 is conducted through the cavity to the end of the comb teeth, achieving directional irradiation in combination with the light emission design of the end face. The above structures can be flexibly selected according to the actual optical requirements to balance light guiding efficiency and structural strength.

[0029] In the laser hair growth device 10 of this embodiment, the attachment member 100 includes a plurality of spaced-apart comb teeth 110, the comb teeth 110 extending outward from the connecting part 120, and the laser light panel 200 is connected to the comb teeth 110. The comb teeth 110 are used to guide light and comb the hair roots when attached. During use, the comb teeth 110 are inserted between the hairs, parting the hair and combing the hair roots, effectively preventing the laser from being blocked by the hair and allowing the laser to act more directly on the scalp. At the same time, the laser light panel 200 is provided on the comb teeth 110, and the laser is emitted from the bottom of the comb teeth and guided through the comb teeth 110. The distance from the laser light source to the scalp is significantly shortened, reducing energy attenuation in the laser propagation path, thereby improving the efficiency of laser irradiation to the hair follicles and the therapeutic effect.

[0030] In the laser hair growth device 10 of this embodiment, the connection part 120 has a transparent structure in at least a portion of it, which, in combination with the light-guiding function of the comb teeth 110, helps to ensure uniform output and distribution of the laser. Furthermore, the open structure formed by the spaced-out comb teeth 110 is advantageous because the heat generated when the laser light panel 200 is operating is naturally dissipated by air convection, preventing heat from accumulating locally on the scalp, reducing stuffiness during use, and improving comfort during prolonged use.

[0031] The laser hair growth device 10 of this embodiment employs a comb-like structure instead of the conventional helmet-type or cap-type sealed structure, resulting in a lighter and more compact overall structure, reduced pressure on the head when worn, improved stability and comfort during wear, and easier portability and daily use.

[0032] The laser hair growth device 10 of this embodiment employs an open-type comb structure as a whole, significantly reducing the overall weight and the feeling of pressure on the head compared to conventional helmet-type or cap-type devices. The connecting part 120 can be designed in an arc shape or a flexible structure that conforms to the contour of the head to improve the fit and stability of the device. At the same time, since it does not need to cover the entire head, the device is smaller in volume, making it easy to store and carry, and is more suitable for daily use at home or on the go. As described above, the laser hair growth device 10 ensures therapeutic effect while also achieving thermal management, wearing comfort, and ease of use, possessing good practical value and future market application potential.

[0033] Specifically, a mounting groove 111 is provided in the comb teeth portion 110, the laser light panel 200 is housed within the mounting groove 111, and the laser hair growth device 10 further includes a housing 400 provided to cover the mounting groove 111.

[0034] By embedding the laser light panel 200 in the mounting groove 111 and covering and fixing it with the housing 400, the laser light panel 200 completely covers the cavity formed by the comb teeth 110 and the housing 400 in the thickness direction, thereby effectively reducing the overall thickness of the mounting member 100 structure in the direction perpendicular to the extension direction of the comb teeth, improving the fit and comfort when worn.

[0035] The inner wall contour of the mounting groove 111 conforms to the external shape of the laser light panel 200, and during the assembly process, it can act to restrict the position of the laser light panel 200 in the length, width, and height directions, ensuring that it does not shift or loosen during use, thereby guaranteeing the stability of the irradiation position of the laser light source and improving the consistency of the treatment effect. The housing 400 can be connected to the comb teeth 110 using methods such as snap-fit, screws, or adhesive, and the specific connection method can be selected according to the product's airtightness, ease of attachment and detachment, and structural strength requirements. For example, in the case of snap-fit ​​connection, elastic hooks can be provided on the edge of the housing 400 and slots can be provided at the corresponding positions on the comb teeth 110 to enable rapid assembly. When using screw connection, screw holes can be pre-provided in the joint area between the housing 400 and the comb teeth 110, and secure fastening can be achieved with fasteners, which is advantageous for subsequent maintenance or replacement of the laser light panel 200. Furthermore, the housing 400 also provides dustproof, waterproof, and internal electronic component protection, improving the overall environmental adaptability of the device and extending its service life.

[0036] In one embodiment, the comb teeth 110 is further provided with a light guide strip 112, which is located on the side opposite the mounting groove 111, and which is used to come into contact with the human body.

[0037] By providing the light guide strip 112 on the side of the comb teeth 110 closest to the scalp, the light rays emitted from the light source can propagate through the light guide strip 112 and approach the scalp surface. This shortens the optical path distance, reduces scattering and attenuation of the light rays in the air, improves the utilization rate of light energy, and is advantageous for improving the laser irradiation effect on scalp tissue. The light guide strip 112 can be manufactured from materials with good light transmittance and high biocompatibility, such as polymethyl methacrylate (PMMA), polycarbonate (PC), or medical-grade silicone, to ensure safety and comfort when in contact with the human body.

[0038] In some embodiments, the light guide strip 112 extends along the length of the comb teeth 110 to broaden the laser coverage area. Specifically, the length of the light guide strip 112 may be approximately equal to the length of the main body of the comb teeth 110, or it may cover the area on the comb teeth 110 where multiple comb teeth are provided, thereby enabling continuous irradiation of a wider area of ​​the scalp during the combing process.

[0039] The cross-sectional shape of the light guide strip 112 may be rectangular, semicircular, or arc-shaped to improve fit with the outer shape of the comb-tooth section 110. If the light guide strip 112 extends along its length, microstructures (such as microprism arrays, scattering particles, or surface roughening treatments) can be incorporated internally to adjust and control the uniformity of the light emission angle and distribution, avoiding localized light intensity that is too high or too low, thereby improving the uniformity of treatment or care. If the extension length of the light guide strip 112 is too short, the irradiation area may be limited, and the wide-area benefits that laser treatment can cover may not be fully realized. On the other hand, if the extension length is too long and exceeds the effective operating area of ​​the comb-tooth section 110, it may result in material waste and structural redundancy, affecting the compactness of the overall structure. Therefore, the extension length of the light guide strip 112 can be optimized according to the actual usage requirements and the dimensions of the comb-tooth section 110, and is not uniquely limited here.

[0040] In one embodiment, the housing 400 is a TPU housing, a silicone housing, or a soft rubber housing. TPU (thermoplastic polyurethane) material has good elasticity, abrasion resistance, oil resistance, and tear resistance, which can effectively improve the service life and structural stability of the housing 400 under complex working conditions. By using TPU material for the housing 400, when subjected to external impacts, the elastic deformation of the material itself absorbs some of the energy, reducing the risk of damage to the internal structure. In addition, it can provide a good grip and anti-slip properties, improving the interaction experience between humans and machines. Furthermore, because TPU material has a certain degree of transparency and colorability, it is easy to customize the color or design a transparent structure according to the appearance requirements of the product, thereby improving the visual identification of the product. In specific implementation, the housing 400 can be integrally molded by an injection molding process, ensuring structural integrity and airtightness, making it suitable for housing applications of machinery or electronic equipment where there are comprehensive requirements for lightweight, flexibility, and protective performance.

[0041] When silicone material is used for the housing 400, the silicone material has excellent biocompatibility and chemical stability, and its operating temperature range can be -60°C to +200°C, allowing it to maintain stable physical performance at different ambient temperatures. The silicone material has low surface energy and natural anti-adhesion properties, making it easy to clean and maintain. Furthermore, its high transparency allows the user to intuitively observe the operating status of the internal laser light panel 200.

[0042] When the housing 400 is designed from soft rubber material, the cushioning properties of the material itself can protect the internal structure from external impacts, and it can also provide a good grip and anti-slip properties, improving the safety and comfort of the user during operation. The surface of soft rubber material generally has a certain coefficient of friction, increasing the contact friction force with the skin of the hand, and preventing the device from unintentionally slipping during use. Furthermore, when the soft rubber material is subjected to pressure, it undergoes a moderate deformation, which can better conform to the contour shape of the comb teeth 110, resulting in a tighter fit and improving the sealing performance of the entire structure.

[0043] Furthermore, the attachment member 100 further includes an attachment portion 130 connected to the end of the connecting portion 120, and the laser hair growth device 10 further includes a control assembly 300 connected to the attachment portion 130.

[0044] In this embodiment, the control assembly 300 can be used to control operations such as starting and stopping the laser light panel 200, switching operating modes, adjusting output power, and timer functions. Since the control assembly 300 is provided on the mounting member 100, the laser hair growth device 10 can be easily attached as a single unit, and the user can control the laser light panel 200 without having to hold or operate any external devices separately while wearing the device, thus improving the convenience of use and the continuity of operation.

[0045] Specifically, the mounting portion 130 can be manufactured from a flexible material such as silicone, a stretchable fabric, or a memory metal frame with a flexible coating to fit the head contours of various users and improve comfort during wear. The mounting portion 130 and the connecting portion 120 can be connected using a fixed or removable connection method, such as a snap-fit ​​structure, a magnetic structure, or a screw fastener. When a removable connection is used, the user can easily replace, charge, or maintain the control assembly 300.

[0046] Furthermore, the control assembly 300 can also integrate wireless communication modules, such as a Bluetooth module or a Wi-Fi module, to enable functions such as remote control, usage record storage, or firmware upgrades by exchanging data with external smart devices (such as mobile phones or tablets). The housing of the control assembly 300 can be manufactured from lightweight engineering plastic or metal material with a certain strength to protect the internal electronic components and reduce the overall weight. Integrating the control assembly 300 into the mounting section 130 not only optimizes the overall structural layout of the device but also avoids problems with entanglement and pulling by external control cables, further improving the stability and reliability of the laser hair growth device 10 during actual use.

[0047] In one embodiment, the mounting member 100 is an arc-shaped structure that forms a mounting space for accommodating the head. An arc-shaped structure refers to a structure in which the overall contour of the mounting member 100 extends along a spatial curve, forming a three-dimensional arc shape with a constant radius of curvature. The design principle of the arc-shaped structure is based on the geometric characteristics of the human head, thereby determining the optimal arc-shaped contour of the mounting member 100. An arc-shaped structure can be mathematically represented as an arc, an elliptical arc, or a more complex free curve, and arc-shaped structures are widely adopted because they are easy to manufacture and provide a good fit.

[0048] The arc-shaped structure of the mounting member 100 conforms to the natural contours of the human head due to its geometric shape, forming a multi-point contact support method. This multi-point contact method evenly distributes the overall weight of the laser hair growth device 10 across multiple contact points on the head, avoiding localized pressure caused by weight concentration at a single point. Furthermore, the continuous curved design of the arc-shaped structure eliminates the stress concentration that can occur with the connection of straight segments, improving the structural strength and durability of the mounting member 100. The arc-shaped structure also possesses excellent mechanical distribution characteristics; when an external load is applied, the load is transmitted throughout the structure along the arc-shaped contour, preventing structural failure due to excessive localized stress.

[0049] In this embodiment, the attachment member 100 is provided with an arc-shaped structure, allowing it to conform to the human head. Conformity means that the inner surface of the attachment member 100 and the outer surface of the user's head are in close contact, and the gap between them is controlled to be within a narrow range. The good conformity effect ensures that the laser hair growth device 10 is maintained in a stable position on the user's head, and the impact on the accuracy of laser irradiation and the treatment effect due to displacement of the device can be avoided. The realization of the conformity effect depends on the geometric precision of the arc-shaped structure of the attachment member 100 and the flexibility of the material. Geometric precision ensures that the shape of the attachment member 100 conforms to the contour of the head, and the flexibility of the material allows the attachment member 100 to deform within a certain range to adapt to individual differences.

[0050] The arc-shaped structure of the mounting member 100 also takes ergonomic principles into consideration, improving wearing comfort by optimizing the pressure distribution on the contact surface. The human head has different sensitivity to pressure depending on the area; for example, the temples are relatively sensitive, while the top and back of the head can withstand relatively large pressures. The arc-shaped structure of the mounting member 100 can differentiate the pressure distribution by adjusting the radius of curvature in different areas, reducing pressure in sensitive areas and appropriately increasing pressure in areas with high load-bearing capacity, thereby ensuring stability during wear while maximizing user comfort.

[0051] The manufacture of arc-shaped structures can be achieved through various processes such as injection molding, press molding, 3D printing, or machining. Injection molding is applicable to mounting components 100 made of plastic material, allowing for the formation of complex arc-shaped contours in a single step and providing excellent surface quality. Press molding is applicable to thin metal sheet materials, allowing for the acquisition of the required arc shape through mold press deformation, offering the advantages of high production efficiency and low cost. 3D printing technology can manufacture any complex arc-shaped structure, is suitable for custom-made applications, and can generate a dedicated arc-shaped contour based on the user's head scan data. Machining is suitable for metal mounting components 100 with extremely high precision requirements, obtaining a precise arc-shaped surface through numerically controlled milling or turning.

[0052] Specifically, the control assembly 300 includes a control button 310, a circuit board 320, and a control cover 330. The control cover 330 and the mounting portion 130 are detachably connected and enclose each other to form a mounting space. The circuit board 320 is located within the mounting space, and the control button 310 is connected to the circuit board 320.

[0053] In this embodiment, the method for removably connecting the control cover 330 and the mounting portion 130 may be a snap-fit ​​structure, a screw connection, or a magnetic connection. For example, the edge of the control cover 330 may be provided with multiple snap-fit ​​protrusions, and correspondingly, the mounting portion 130 may be provided with slots, allowing assembly and disassembly by pressing, and facilitating maintenance or replacement of the internal circuit board 320 by the user.

[0054] The control cover 330 can be made of an engineering plastic with a certain level of strength and insulating properties, such as polycarbonate or ABS, to ensure protection of the internal electronic components and prevent interference from external electromagnetic interference. The circuit board 320 integrates a microcontroller, a power management module, and a signal processing module for receiving trigger signals from the control button 310 and executing corresponding commands.

[0055] The control buttons 310 may be mechanical buttons, membrane buttons, or condenser-type touch buttons, and their number may be one, two, or more than one, without any unique limitation. By providing multiple control buttons 310, various functions of the device can be controlled individually, improving ease of operation and the efficiency of human-machine interaction. The control buttons 310 are fixed to the circuit board 320 by welding, plugging, or flexible circuit connection, ensuring the stability of signal transmission. After assembling the control cover 330 and mounting part 130 in place, some of the structure of the control buttons 310 is exposed on the surface of the control cover 330, making it easy for the user to press them. The control cover 330 also provides airtight protection for the circuit board 320, effectively preventing contaminants such as sweat and dust from entering the mounting space, improving the environmental adaptability of the control assembly 300 and extending its service life.

[0056] In one embodiment, the laser hair growth device 10 further includes a flexible pad 500 connected to the attachment part 130, and the flexible pad 500 is used to come into contact with the human body.

[0057] By adopting the flexible pad 500, the comfort of wearing the device can be improved, and by forming a buffer layer between the attachment part 130 and the human head, the pressure caused by prolonged wear or the weight of the device itself can be reduced, and at the same time, discomfort and localized pressure marks caused by unprotected contact between the device and the skin can be reduced.

[0058] Specifically, the flexible pad 500 may be made of TPU material and is bonded to the mounting part 130 with TPU adhesive. TPU (thermoplastic polyurethane) material has good elasticity, abrasion resistance and biocompatibility, is suitable for contour changes of different head shapes, and can improve the fit. Furthermore, applying a skin-friendly finish to the surface of the TPU material can further enhance comfort during wear. The flexible pad 500 and the mounting part 130 are bonded with TPU adhesive, making them less likely to detach even during long-term use, and avoiding interference with wearing comfort caused by the use of rigid connection structures such as screws or snap-fits. Note that the material of the flexible pad 500 is not limited to TPU, and other flexible materials with similar elasticity and skin-friendly properties such as silicone, EVA (ethylene-vinyl acetate copolymer), or latex can be selected and specifically determined according to the actual design requirements, and are not uniquely limited here.

[0059] Furthermore, mounting holes 131 are provided in the mounting portion 130, the circuit board 320 is connected to the mounting holes 131 via fasteners, one opening of the mounting holes 131 is located on the side of the mounting portion 130 away from the circuit board 320, and the flexible pad 500 is provided to cover the opening of the mounting holes 131. This not only improves the comfort of mounting with the flexible pad 500, but also allows the flexible pad 500 to cover the mounting holes 131 after the fasteners have been assembled.

[0060] Specifically, the fasteners may be screws, pins, snap-fits, or rivets, and are used to securely fix the circuit board 320 within the mounting holes 131 of the mounting section 130. When screws are used as fasteners, removal and maintenance can be easily performed, and when pins or rivets are used, higher connection stability can be provided, making them suitable for applications with high structural strength requirements. The fasteners penetrate the corresponding through holes on the circuit board 320 and then fit securely into the mounting holes 131, thereby securely attaching the circuit board 320 to the mounting section 130.

[0061] Since the opening of the mounting hole 131 is located on the side of the mounting part 130 away from the circuit board 320, the tip or operating end of the fastener is located on the inside of the mounting part 130 (i.e., the side closer to the user's skin), and the circuit board 320 is located on the outside of the mounting part 130. This arrangement avoids discomfort and abrasions to the user caused by exposed fasteners and provides a structural base for subsequently covering the flexible pad 500. The flexible pad 500 can be made of a soft and resilient material such as silicone, rubber, or thermoplastic elastomer (TPE), which covers the opening of the mounting hole 131 and not only shields the tip of the fastener but also reduces contact pressure between the mounting part 130 and the user's skin during wear, improving comfort during prolonged wear.

[0062] Furthermore, the flexible pad 500 and the mounting portion 130 can be fixed together by means of adhesion, locking, or interlocking. For example, a flange structure can be provided on the edge of the flexible pad 500 and fitted into a corresponding groove on the mounting portion 130 to ensure secure positioning, or a medical adhesive can be applied to the back surface of the flexible pad 500 to attach it to the surface of the mounting portion 130. In any of the above connection methods, it is possible to ensure that the flexible pad 500 does not fall off during use and that it can be easily removed when maintenance or replacement of the circuit board 320 is required.

[0063] In one embodiment, the laser hair growth device 10 further includes a vibration assembly 600 connected to the attachment member 100.

[0064] By providing the vibration assembly 600, tactile feedback can be provided during operation of the device to inform the user of the current operating status of the device. Specifically, the vibration assembly 600 can generate vibration when the laser hair growth device 10 is powered on to confirm that the device has started up normally, and when the user switches operating modes (for example, switching from low power mode to high power mode, or from continuous irradiation mode to pulsed irradiation mode), the vibration assembly 600 will vibrate once or more to intuitively provide feedback that the mode switching operation has already been identified or performed. Furthermore, when the set treatment time is completed and laser irradiation stops, the vibration assembly 600 can similarly be triggered to vibrate, informing the user that the treatment process is complete and allowing them to quickly remove the device or perform subsequent operations.

[0065] Specifically, the vibration assembly 600 includes a vibration motor and a motor cover 610, and has two mounting sections 130, each connected to opposite ends of a connecting section 120. The control assembly 300 is mounted on one of the mounting sections 130, the motor cover 610 is mounted to cover the other mounting section 130, and the vibration motor is housed within the motor cover 610. This structural layout, with its spatial separation of the control assembly 300 and the vibration assembly 600, helps to avoid adverse effects on the control circuit due to electromagnetic interference or mechanical vibration, and is also advantageous for the modular assembly of internal components and subsequent maintenance.

[0066] The vibration assembly 600 may include a micro-vibration motor, an eccentric wheel structure, and a corresponding mounting bracket, the micro-vibration motor generating periodic vibrations by the rotation of the eccentric wheel, and the mounting bracket is used to stably mount the vibration assembly 600 inside the housing of the mounting member 100.

[0067] Furthermore, the vibration assembly 600 can be electrically connected to the main control module of the laser hair growth device 10, which transmits control signals according to the operating status of the device to precisely control the timing and form of the vibration trigger. The vibration assembly 600 can be powered collectively by the built-in power supply of the laser hair growth device 10, eliminating the need for a separate independent power supply, which simplifies the structure and reduces overall power consumption. The housing material of the vibration assembly 600 can be selected from engineering plastics or elastomers with certain vibration absorption properties, such as polycarbonate (PC), thermoplastic polyurethane (TPU), or silicone, thereby reducing the transmission of vibration energy in non-target directions and avoiding interference with the laser module or other precision elements. The motor cover 610 adopts an external contour that matches the mounting part 130 and can be securely connected to the mounting part 130 by snap-fit, screw, or ultrasonic welding, thereby ensuring that the vibration motor does not displace or loosen during operation, guaranteeing consistency of vibration feedback and reliability for long-term use.
