[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0041] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0042] Reference Figure 1 and Figure 2The utility model provides a beauty instrument, including an operating part 100 and a working part 200, wherein the operating part 100 and the working part 200 are detachably connected. The beauty instrument provided by the utility model also includes a main control circuit board 1 and a light-emitting component 2, wherein:

[0043] A main control circuit board 1 is provided in the operating part 100;

[0044] The light-emitting assembly 2 is disposed in the working part 200 , and includes a circuit board 21 and a light-emitting element 22 disposed on the circuit board 21 . The circuit board 21 is electrically connected to the main control circuit board 1 .

[0045] In this embodiment, the beauty instrument is composed of an operating part 100 and a working part 200, which are connected in a detachable manner, so that the beauty instrument is convenient for users to hold and operate, and it is also convenient to clean and replace the working parts.

[0046] The main control circuit board 1 is arranged in the operating part 100, and is responsible for controlling the entire beauty instrument circuit and the circuit control operations such as program operation. The light-emitting component 2 arranged in the working part 200 includes a circuit board 21 and a plurality of light-emitting components 22. The circuit board 21 is electrically connected to the main control circuit board 1 to ensure that the light-emitting component 2 can receive the electrical signal from the main control circuit board 1, so that the light-emitting component 2 can emit light through the light-emitting components 22 to illuminate the target skin area for phototherapy.

[0047] Compared with the assembly and disassembly problems caused by the circuit board of the existing beauty instrument that needs to be connected to the light-emitting part 22 from the operating part to the working part, in the present application, since the circuit board is separately arranged in the operating part 100 and the working part 200, this design makes the independence between the components stronger. During maintenance and upgrades, users or technicians can more easily replace or repair individual parts without disassembling the entire device, thereby reducing maintenance costs and complexity.

[0048] At the same time, the separate circuit board design reduces the possibility of overall device damage due to circuit failure. For example, if there is a problem with the circuit board 21 of the working part 200, it will not affect the main control circuit board of the operating part, and the circuit board 21 can be replaced alone.

[0049] Furthermore, the independent circuit board design allows each part to focus on its functional requirements, making it more flexible to add new functions or upgrade existing functions in the future. For example, only the light emitting assembly 2 of the working part 200 can be upgraded to add more types of light therapy functions without changing the main control circuit board 1 of the operating part 100, and vice versa.

[0050] Furthermore, the modularization of the circuit board into the main control circuit board 1 and the circuit board 21 in the present application solution allows the manufacturer to quickly iterate new models of beauty devices according to market demand. The main control circuit board 1 or the circuit board 21 on the operating part 100 or the working part 200 can be upgraded separately without redesigning the entire device.

[0051] In summary, the design of separately setting up the circuit boards in the present application not only improves the maintenance convenience and safety of the beauty instrument, but also enhances the flexibility and expansibility of the functions. The structure is simple and easy to assemble and disassemble.

[0052] Reference Figure 2 and Figure 3 In some embodiments, the circuit board 21 proposed in the embodiment of the utility model is provided with a first electrical connector 211, and the main control circuit board 1 is provided with a second electrical connector 11 corresponding to the first electrical connector 211, and the first electrical connector 211 is electrically connected to the second electrical connector.

[0053] In this embodiment, the main control circuit board 1 and the circuit board 21 proposed in the present application scheme can be electrically connected through the first electrical connector 211 and the second electrical connector 11, realizing a quick connection and disconnection mechanism. The user can easily replace different working parts or perform maintenance, thereby improving the flexibility and convenience of using the equipment.

[0054] During the disassembly and assembly process, the first electrical connector 211 and the second electrical connector 11 on the circuit boards in the working part 200 and the operating part 100 can be disassembled first to connect or separate the main control circuit board 1 and the circuit board 21. When connected, the main control circuit board 1 can supply power and transmit control signals to the circuit board 21 through the two electrically connected electrical connectors, so that the light-emitting component 2 of the working part 200 starts working according to the preset program.

[0055] Reference Figure 3 In some embodiments, the first electrical connector 211 and the second electrical connector 11 provided in the embodiments of the present utility model are electrically connected by plugging; or

[0056] The first electrical connection member 211 is electrically connected to the second electrical connection member 11 through an electric wire; or

[0057] The first electrical connection member 211 is electrically connected to the second electrical connection member 11 through a wire connector.

[0058] In this embodiment, one of the possible implementation methods of this embodiment is: two electrical connectors are connected by plugging, and the plugging connection is achieved by physical insertion, usually including male and female docking parts, wherein metal contact points are physically contacted during insertion to form an electrical connection.

[0059] The user can align the male connector (assuming the first electrical connector 211) and insert it into the female connector (assuming the second electrical connector 11). The connector is usually designed with a guide mechanism and a fixing structure (such as a slot) to ensure a correct and firm connection.

[0060] After the insertion is completed, the circuit connection is established and the beauty instrument can start working.

[0061] The plug-in connection has the following effects: the connection process is fast, direct, and easy to operate. It can provide a stable and reliable electrical connection and is suitable for equipment parts that need to be frequently disassembled and connected.

[0062] Another possible implementation of the present application scheme: electrical connection by wires, that is, connecting two electrical connectors by wires, and the two ends of the wires can be connected to their respective electrical connectors through terminals, and current and signals are transmitted through the conductive material (such as copper wire) in the wires.

[0063] One of the two ends of the wire can be fixed to the first electrical connector 211 , and the other end can be detachably connected to the second electrical connector 11 .

[0064] The effect of electrical connection through wires is that it allows a certain degree of physical location flexibility. Due to the existence of wires, the electrical connectors can be indirectly electrically connected, so that the two can maintain a certain distance and space for movement. It is suitable for occasions where the internal space is small or the components need to be moved.

[0065] Another possible implementation of the present application scheme: two electrical connectors are electrically connected through a wire connector, and the electrical connector can be plug-in connected to each other, or can be connected through wires like a terminal block, so that the wire connection can be easily connected and disconnected. The connector is usually designed with anti-misplugging and waterproof and dustproof functions to improve the stability and durability of the connection.

[0066] The effect of connecting through an electrical connector is that it provides higher flexibility and safety, and facilitates equipment maintenance and component replacement.

[0067] In summary, the above three connection methods have their own advantages and applicable scenarios. The choice of which method depends on the actual design requirements, cost considerations and usage environment of the beauty instrument. For example, plug-in connection is fast and convenient, and is suitable for beauty instruments that need to replace parts; while wire connection and wire connector connection provide greater flexibility and maintainability, and are suitable for beauty instruments with complex internal structures or requiring maintenance space.

[0068] Reference Figure 3 and Figure 4In some embodiments, the light-emitting component 2 provided in the embodiment of the utility model further includes at least two first connecting members 23 , the two first connecting members 23 are arranged at intervals, and the light-emitting member 22 is electrically connected to the circuit board 21 through the first connecting members 23 .

[0069] In the present embodiment, in the design of the light-emitting component 2 of the beauty instrument, the design of using at least two first connectors 23 to connect the light-emitting component 22 and the circuit board 21 is based on the considerations of improving electrical stability, increasing structural support and optimizing lighting effects.

[0070] Multiple connections can provide more uniform current distribution to the light emitting element 22, reduce the risk of single connection point failure, and thus improve the stability and reliability of the entire circuit.

[0071] In addition, the stability of the fixation is enhanced. Two or more connecting members can better fix the light-emitting member 22 to the circuit board 21, which is particularly important for preventing the light-emitting member 22 from being physically displaced due to use or vibration.

[0072] The first connecting member 23 is usually made of conductive material, such as metal pins or pins, which ensure electrical connection between the light emitting member 22 and the circuit board 21 .

[0073] During the installation process, when the light emitting element 22 is assembled on the circuit board 21, it is positioned and fixed by the first connecting member 23. Usually, the first connecting member 23 is preset at a specific position on the circuit board, and the light emitting element 22 can be inserted accordingly during the assembly process.

[0074] After the physical assembly is completed, the first connector 23 ensures that a conductive path between the light emitting element 22 and the circuit board 21 is established, allowing the transmission of current and control signals.

[0075] After the beauty instrument is started, the current is transmitted to the light-emitting element 22 through the first connecting member 23. The light-emitting element 22 is started and emits light according to the control signal to illuminate the target skin area for skin treatment.

[0076] The present application solution disperses electrical load and mechanical stress through multiple connection points, reduces the possibility of single point failure, and increases the reliability of the circuit connection of the beauty instrument. In addition, multiple connectors can provide better flexibility when the light emitting element 22 needs to be replaced or repaired.

[0077] Reference Figure 4 In some embodiments, the circuit board 21 provided in the embodiment of the utility model is provided with a plurality of connection holes 212;

[0078] One end of the first connecting member 23 connected to the circuit board 21 is configured with a connecting terminal 231 corresponding to the connecting hole 212 , and the connecting terminal 231 is electrically connected to the connecting hole 212 .

[0079] In this embodiment, the connection hole 212 provides a precise positioning point for receiving the connection terminal 231 of the first connection member 23. This physical and electrical docking can be achieved by mechanical processing to ensure that the connection terminal 231 can be accurately inserted into the connection hole. The connection terminal 231 is usually made of a conductive material, such as metal. When the connection terminal 231 is inserted into the connection hole 212, a stable electrical contact is formed between the circuit board 21 and the first connection member 23, thereby achieving continuous current transmission.

[0080] When assembling the light-emitting component, first align the connection terminal 231 of the first connector with the connection hole 212 on the circuit board. Then the insertion operation is performed: the connection terminal 231 is inserted into the connection hole 212, which usually requires a certain insertion force to ensure a tight contact between the terminal and the hole. In some designs, additional mechanical locking mechanisms such as twist buckles, snap buckles, etc. may be used to further secure the connection.

[0081] The connection terminal 231 is inserted into and fixed in the connection hole 212 , and an electrical connection between the light emitting element 22 and the circuit board 21 is established, so that current and signals can be transmitted from the circuit board 21 to the light emitting element 22 .

[0082] The present application solution can assemble the circuit quickly and accurately by providing the connection hole 212 and the corresponding connection terminal 231, reduce manual errors, and improve the assembly speed. In addition, the connection method proposed in the present application solution can provide a more stable and reliable physical and electrical connection than traditional welding or other bonding methods. If the light-emitting element 22 or the circuit board needs to be replaced or maintained, it can be easily disassembled and reconnected through the design of the connection hole and the terminal.

[0083] Reference Figure 4 In some embodiments, columnar terminals 221 are provided at both ends of the main body of the light-emitting member 22 proposed in the embodiment of the utility model, and a card interface 232 for clamping the columnar terminal 221 is constructed at one end of the first connecting member 23 connected to the light-emitting member 22.

[0084] In this embodiment, the mechanical connection: the card interface 232 is generally designed as an elastic mechanism that can tightly surround or clamp the columnar terminal 221 and use mechanical clamping force to maintain the stability of the connection. This design uses physical shape and elastic force to achieve a stable mechanical connection.

[0085] The contact surface between the column terminal 221 and the card interface 232 is usually made of metal material to ensure good electrical conductivity. When the column terminal 221 is clamped by the card interface 232, an electrical connection is formed between the two.

[0086] In some embodiments, during the assembly process, the columnar terminal 221 of the light emitting member 22 is aligned with the card interface 232 of the first connector 23, and the two can be connected by interference fit. When the columnar terminal 231 is fully inserted into the card interface 232, the card interface 232 can be tightly connected to the columnar terminal 221 to achieve mechanical locking. This locking not only maintains the stability of the electrical connection, but also prevents the connection from loosening due to vibration or movement.

[0087] Through the above-mentioned setting, the present application scheme effectively simplifies the assembly process by means of the card-type connection method, and the operator can complete the assembly without using complicated tools, thereby reducing the assembly cost and time. The physical locking mechanism provided by the card interface ensures the long-term stability of the connection and reduces failures caused by poor connection. If the light-emitting element 22 needs to be replaced or maintained, the card-type design makes the disassembly process quick and simple, thereby improving the overall maintenance efficiency.

[0088] In summary, the present application solution not only ensures the efficiency of assembly and the reliability of connection, but also improves the overall maintenance and operating convenience of the beauty instrument.

[0089] Reference Figure 3 and Figure 5 In some embodiments, the circuit board working part 200 provided in the embodiment of the utility model includes a heat sink 4 , which is disposed between the light emitting parts 22 and 21 , and the heat sink 4 is provided with heat dissipation fins 41 .

[0090] In this embodiment, the heat sink 4 can be made of a material with high thermal conductivity (such as aluminum or copper) and can quickly receive heat from the light emitting element 22. Heat can be transferred from the heat source (i.e., the light emitting element 22) to the heat sink 4 body, and then dissipated through the heat sink fins 41.

[0091] The heat sink fins 41 are designed to increase the heat dissipation surface area, thereby promoting air flow and heat exchange. When the beauty instrument is running, the air flow through the air exchange between the inside and outside can take away the heat on the heat sink fins 41, and the temperature can be effectively reduced by convection effect.

[0092] Heat absorption: When the light-emitting element 22 generates heat during use, the heat sink 4 absorbs the heat, and the heat is conducted to the heat sink 41 through the base of the heat sink 4. The heat sink 41 dissipates the heat to the surrounding environment. Since the heat sink 41 increases the surface area in contact with the air, the heat dissipation efficiency is increased, and the heat diffusion is accelerated. Through effective thermal management, the heat sink 4 keeps the temperature of the light-emitting element 22 and the circuit board 21 within a safe range, preventing damage to electronic components that may be caused by overheating.

[0093] This application scheme achieves the following through the above settings:

[0094] First, improve the stability of the device: a good thermal management system can prevent the light-emitting element 22 from reducing efficiency or being damaged due to high temperature, thereby extending the service life of the beauty instrument.

[0095] Second, maintaining performance consistency: maintaining a stable temperature helps the light emitting element 22 provide continuous and consistent light output, which is helpful for the efficacy of the beauty instrument.

[0096] Third, it enhances user safety: prevents the surface of the grip 100 of the beauty instrument from overheating, ensures the safety of the user during use, and avoids safety accidents such as burns.

[0097] In summary, the design of the heat sink 4 in the present application solution helps to improve the safety and efficiency of the beauty instrument. Through effective heat conduction and heat convection, the heat sink 4 ensures the performance and safe operation of the beauty instrument during long-term operation.

[0098] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments, one side of the circuit board 21 provided in the embodiment of the utility model abuts against the heat dissipation fins 41 , and a heat dissipation film layer is provided on the side of the circuit board 21 abutting against the heat dissipation fins 41 .

[0099] In this embodiment, the heat dissipation film layer is a thermal interface material and can be made of a material with good thermal conductivity, such as thermal grease, graphene sheet or other composite materials.

[0100] When the light emitting element 22 generates heat during use, the heat is first transferred to the circuit board 21 through the first connecting element 23. The heat dissipation film layer provided on the circuit board 21 can dissipate the heat transferred from the light emitting element 22 to the first connecting element 23.

[0101] The use of the heat dissipation film layer effectively enhances the efficiency of the overall heat dissipation system, and to a certain extent enables operation at higher power without overheating.

[0102] Reference Figure 5 In some embodiments, the heat sink 4 proposed in the embodiment of the utility model is configured with a receiving groove 42 on a side facing away from the heat sink fins 41, the main body of the light-emitting component 22 is received in the receiving groove 42, and the columnar terminals 221 located at both ends of the main body of the light-emitting component 22 are exposed in the receiving groove 42.

[0103] In the present embodiment, the arrangement of the accommodating groove 42 enables most of the main part of the light-emitting component 22 to be accommodated inside the heat sink 4, that is, the heat sink 4 surrounds the main part of the light-emitting component 22 in a semi-enclosed state. Without affecting the light emission of the light-emitting component 22, the semi-enclosed state of the accommodating groove 42 further enables the heat exchange between the heat sink 4 and the light-emitting component 22 to be more direct and efficient. This structural design helps the heat sink 4 to quickly absorb and conduct the heat generated by the light-emitting component 22. In addition, by accommodating the main part of the light-emitting component 22 in the accommodating groove 42, the light-emitting component 22 can be protected from impact or extrusion, thereby enhancing the durability and stability of the entire device. The columnar terminal 221 is designed to be exposed in the accommodating groove 42 to facilitate the implementation of electrical connection with the first connecting member 23.

[0104] During the assembly process, the main body of the light emitting member 22 is first placed in the receiving groove 42 of the heat sink, and the columnar terminal 221 is located outside the receiving groove 42 and connected to the first connecting member 23. When the beauty instrument is running, the heat generated by the light emitting member 22 is directly transferred to the heat sink 4, and the heat is quickly dissipated by the heat sink 4 and the heat dissipation fins 41 thereon, thereby maintaining the operating temperature of the light emitting member 22 within a safe range.

[0105] The solution of the present application improves the heat dissipation efficiency through the above-mentioned arrangement. The design of the accommodating groove 42 makes the light-emitting element 22 closer to the heat dissipation element 4, thereby improving the heat dissipation effect and heat dissipation efficiency.

[0106] Reference Figure 1 and Figure 6 In some embodiments, the working part 200 proposed in the embodiment of the utility model includes a first shell 3 detachably connected to the operating part 100, the light-emitting component 2 and the heat sink 4 are arranged in the first shell 3, and the first shell 3 is constructed with a light outlet 30 for the light of the light-emitting component 22 to emit light.

[0107] In this embodiment, the first housing 3 provides structural support to protect the internal components (such as the light emitting component and the heat sink) from external influences, while being easy for the user to operate. The light outlet 30 is designed on the first housing 3 to allow the light emitted by the light emitting component 22 to directly irradiate the target skin area of ​​the user.

[0108] During assembly, the light emitting assembly 2 and the heat sink 4 are installed in the first housing so that the light emitting member 22 of the light emitting assembly 2 is arranged corresponding to the light outlet 30. When the beauty instrument is in operation, the light emitting member 22 generates light, which is directly irradiated onto the target skin area of ​​the user through the light outlet 30 in the first housing 3 for phototherapy.

[0109] The light outlet ensures that the light can be effectively focused on the treatment area, improving the treatment effect and reducing energy waste. The key to the design of the first housing 3 and its internal components is to provide structural protection and enhance the convenience of user operation.

[0110] Reference Figure 6 In some embodiments, the beauty instrument provided in the embodiment of the utility model further includes an auxiliary light component 6 located between the light emitting element 22 and the light outlet 30 , and the auxiliary light component 6 is electrically connected to the circuit board 21 .

[0111] In this embodiment, the light-emitting component 22 serves as the light-emitting component of the beauty instrument of the present application, and one of an IPL lamp, an LED lamp, a laser lamp and a halogen lamp can be preferably used as the light-emitting component 22 of the beauty instrument of the present application.

[0112] If the beauty instrument of the present application is not provided with the light-emitting element 22 as the light-emitting component, the auxiliary light component 6 can also be provided to be used as the light-emitting component of the beauty instrument of the present application.

[0113] If an auxiliary light component 6 is further provided on the basis of the light-emitting component 22, the auxiliary light component 6 can play the role of assisting the light emitted by the light-emitting component 22. Specifically, the auxiliary light component 6 can adjust the light emitted by the light-emitting component 22 to the light outlet 30 to a certain extent, so that the light is softer, which is conducive to achieving a better phototherapy visual effect, thereby making it less likely for the beauty instrument of the present application to affect or damage the user's eyesight during use.

[0114] Reference Figure 6 and Figure 7 In some embodiments, the working part 200 proposed in the embodiment of the utility model also includes a mounting frame 5 connected to the heat sink 4, and the mounting frame 5 is provided with a plurality of through holes 51; the auxiliary light assembly 6 includes a plurality of auxiliary light emitting bodies 61, and the auxiliary light emitting bodies 61 are penetrated in the through holes 51.

[0115] In this embodiment, by evenly distributing the auxiliary light emitters 61 of the auxiliary light assembly 6 in the preset through holes 51 on the mounting frame 5, a uniform layout of the auxiliary light emitters can be achieved, which helps to achieve balanced and wide lighting coverage.

[0116] In addition, the mounting frame 5 is connected to the heat sink 4. This design can utilize the heat dissipation capacity of the mounting frame 5 to help the auxiliary light emitter 61 to effectively discharge heat and prevent overheating from affecting the performance and life of the auxiliary light emitter 71.

[0117] When the beauty instrument is started, the auxiliary light illuminator 61 starts to emit light, and the generated heat is conducted to the heat sink 4 through the contact with the mounting frame 5, thereby effectively dissipating the heat.

[0118] Installing it in the through hole 51 also saves the internal space of the beauty instrument to a certain extent.

[0119] In some embodiments, the auxiliary light emitting body 61 can be a lamp bead.

[0120] The present application scheme adopts the above-mentioned arrangement, i.e., the structural design of a through hole 51 for mounting the auxiliary light emitter is arranged on the mounting frame 5, which not only saves the internal space of the beauty instrument, but also realizes the heat dissipation function of the heat sink 4 on the auxiliary light emitter 61, thereby protecting the auxiliary light emitter 61 from overheating during long-term use.

[0121] Reference Figure 2 In some embodiments, the beauty instrument provided in the embodiment of the present utility model further includes a light-transmitting member 8 disposed at the light outlet 30 .

[0122] In this embodiment, the light emitted by the light emitting element 22 and the auxiliary light emitting body 61 of the auxiliary light assembly 6 passes through the light-transmitting element 8 disposed at the light outlet 30 and then emits outward. The light-transmitting element 8 can be made of sapphire material, which has the following advantages:

[0123] First, the sapphire light-transmitting element 8 has good light-guiding properties and can fully utilize various visible lights emitted by the light source, allowing the lights to pass through the sapphire efficiently with little light loss.

[0124] Secondly, the light passing through the sapphire can form a soft and uniform light output surface to illuminate the skin surface.

[0125] Third, it has good durability. Sapphire has extremely high mechanical strength, corrosion resistance and high temperature resistance, which can make the light-transmitting element 8 work for a long time without performance degradation, thereby ensuring that the beauty instrument maintains a long service life.

[0126] Fourthly, it can prevent users from being burned by direct contact with the light source.

[0127] Reference Figures 6 to 8 In some embodiments, the installation frame 5 proposed in the embodiment of the utility model is arranged in a frame shape, and the through hole 51 is arranged on the side wall of the installation frame 5; the auxiliary light component 6 also includes an adapter circuit board 62, and the adapter circuit board 62 is arranged around the side wall of the installation frame 5, and a plurality of auxiliary light emitting bodies 61 are arranged on the side of the adapter circuit board 62 facing the installation frame 5.

[0128] In this embodiment, by setting a through hole 51 on the side wall of the frame-shaped installation frame 5 and setting the adapter circuit board 62 around the side wall of the installation frame 5, the annular arrangement of the auxiliary light component 6 can be realized, and the output light of the light-emitting part 22 can pass through the middle of the frame-shaped installation frame 5. The various auxiliary light-emitting bodies 61 of the surrounding auxiliary light component 6 can directly act on the output light passing through the middle of the frame-shaped installation frame 5. This structural arrangement not only saves space, but also optimizes the effect of the auxiliary light component 6 on the output light of the light-emitting part 22.

[0129] During assembly, the frame-shaped mounting frame 5 is first installed, and then the auxiliary light emitter 61 is installed in the through hole 51 of its side wall. Next, the adapter circuit board 62 is installed around the side wall, which contains the necessary circuit connections and supporting electronic components. After assembly, the auxiliary light emitter 61 is connected to the main control circuit board 1 through the adapter circuit board 62, allowing the power supply and control signals of the auxiliary light emitter to be directly carried out through the adjacent circuit.

[0130] This application achieves the following through the above settings:

[0131] Firstly, efficient space utilization, by compactly arranging the adapter circuit board 62 and the auxiliary light emitter 61 around the side wall of the installation frame 5, greatly saves the internal space.

[0132] Second, optimized light distribution: the arrangement of a plurality of auxiliary light emitters 61 around the side wall of the mounting frame 5 helps to achieve the adjustment of the output light of the light emitting element 22 by the auxiliary light assembly 6 .

[0133] Third, simplified manufacturing and maintenance process: The adapter circuit board 62 simplifies the electrical connection and assembly process, and also makes maintenance and possible component replacement more convenient.

[0134] Reference Figure 8 In some embodiments, the adapter circuit board 62 provided in the embodiment of the present utility model is a flexible circuit board.

[0135] In this embodiment, the purpose of using a flexible printed circuit board (FPC) as the transfer circuit board 62 is:

[0136] First, the flexible circuit board can be bent, folded or curled, so that it can adapt to spaces of various shapes and sizes, especially in unconventional or compact space designs. In the above-mentioned embodiment, the adapter circuit board 62 needs to surround the side wall of the mounting frame 5. If a general metal circuit board is used, the metal circuit board needs to be set around, which is more difficult to manufacture.

[0137] Secondly, flexible circuit boards are lighter than traditional rigid circuit boards, which helps reduce the weight of the entire beauty instrument and makes the device easier to operate and carry.

[0138] Furthermore, the use of flexible circuit boards can reduce the number of additional connectors and wiring required, because flexible circuit boards can integrate multiple circuit connections through a monolithic design. This not only simplifies the circuit assembly process, but also increases the reliability and durability of the circuit.

[0139] In summary, the present application solution can achieve the following technical effects by setting a flexible circuit board as the transfer circuit board 62:

[0140] First, it can adapt to complex structures: since the design of the mounting frame 5 may include curved or rounded side walls, the flexible circuit board can conform to such a structure and maintain the integrity and functionality of the circuit.

[0141] Second, improve the internal layout: the use of flexible circuit boards allows for a more compact and clear internal layout. It can achieve electrical connections between the auxiliary light emitter 61 and other electronic components without adding extra space.

[0142] Third, simplify the production and assembly process: The customizability and integrated design of flexible circuit boards simplify the production process, reduce the possibility of assembly errors, and improve production efficiency.

[0143] In some embodiments, the adapter circuit board 62 may also be a control circuit board made of a hard material. The control circuit board made of a hard material is less adaptable than a flexible circuit board, but the control circuit board made of a hard material has better structural stability and is not easily damaged. Technical personnel in this field may choose according to actual needs, or may adopt a combination of a partially flexible circuit board and a partially hard control circuit board.

[0144] Reference Figure 2 and Fig. 9 In some embodiments, the beauty instrument proposed in the embodiment of the utility model also includes an electrode 7, which is disposed in the first shell 3, one end of the electrode 7 is disposed on the inner side of the first shell 3, and is electrically connected to the adapter circuit board 62 or the circuit board 21; the other end is exposed on the outer side of the first shell 3.

[0145] In this embodiment, the inner end of the electrode 7 is connected to the adapter circuit board 62 or the circuit board 21, that is, the electrode 7 can be electrically connected to the main control circuit board 1 through the adapter circuit board 62 or the circuit board 21 and controlled by the main control circuit board 1.

[0146] The outer end of the electrode 7 is exposed outside the first shell 3 and can directly contact the user's skin for microcurrent therapy, which can help improve the firmness of the skin, promote blood circulation or enhance the skin's ability to absorb skin care products.

[0147] Through the above settings, this application achieves the following effects:

[0148] First, the treatment effect is enhanced: the electrical treatment of the skin by the electrode 7 can effectively improve the treatment effect, such as stimulating the skin through microcurrent technology to promote the production of collagen, thereby achieving anti-aging and skin tightening effects. Second, multi-functional integration: integrating electrodes in beauty devices can increase the versatility of the device, so that it can not only perform skin treatment through phototherapy, but also provide a more comprehensive skin care solution through electrotherapy. That is, the electrode 7 assists the light therapy of the light-emitting component 2 to assist in the user's skin beauty.
