Description

Technical Field

[0001] This utility model relates to the field of beauty equipment technology, and in particular to an accessory head for a beauty device and the beauty device itself. Background Technology

[0002] In the modern home beauty industry, beauty devices are highly favored as core products. They can regulate according to the body's physiological functions, thereby improving the skin condition of the body and face, making them a popular choice for consumers' daily beauty care. With technological advancements, the functions of beauty devices have continuously expanded, covering multiple dimensions such as whitening, skin rejuvenation, freckle removal, wrinkle reduction, and hair removal. Furthermore, based on different technological principles such as ultrasonic induction, photon skin rejuvenation, and radiofrequency skin tightening, a wide variety of product types have emerged.

[0003] Beauty devices, primarily hair removal devices, rely on high-voltage circuits to drive related components (such as LED lights). Therefore, the safety design of high-voltage connections is crucial for ensuring stable device operation and user safety. In traditional beauty device designs, due to the relatively ample internal space, large circuit boards are typically used. By rationally planning the positive and negative high-voltage traces on this large circuit board, the electrical clearances and creepage distances between them meet safety requirements, effectively preventing arcing and insulation breakdown.

[0004] In recent years, to improve the ease of use and maintenance flexibility of beauty devices, the industry has gradually adopted a combined structure design of the main body and the accessory head. However, due to the miniaturization of the accessory head, its internal space is relatively compact. Under these circumstances, how to rationally arrange the positive and negative high-voltage wiring within a limited space, while meeting the strict safety regulations on electrical clearances and creepage distances, has become a technical challenge that urgently needs to be solved.

[0043] Beauty devices, primarily hair removal devices, rely on high-voltage circuits to drive related components (such as LED lights). Therefore, the safety design of high-voltage connections is crucial for ensuring stable device operation and user safety. In traditional beauty device designs, due to the relatively ample internal space, large circuit boards are typically used. By rationally planning the positive and negative high-voltage traces on this large circuit board, the electrical clearances and creepage distances between them meet safety requirements, effectively preventing arcing and insulation breakdown.

[0044] In recent years, to improve the ease of use and maintenance flexibility of beauty devices, the industry has gradually adopted a combined structure design of the main body 200 and the auxiliary head 100. However, due to the miniaturized design of the auxiliary head 100, its internal space is relatively compact. Under these circumstances, how to rationally arrange the positive and negative high-voltage wiring within the limited space, while meeting the strict safety regulations on electrical clearances and creepage distances, so as to house the high-voltage circuit drive-related components in the auxiliary head 100, has become a technical challenge that urgently needs to be solved.

[0045] To address the aforementioned deficiencies, this utility model provides an accessory head 100 for a beauty device. The beauty device can be a hair removal device, or similar, but is not limited to these. In addition to the accessory head 100, the beauty device also includes a main body 200. The main body 200 houses a main controller and a high-voltage power module. One end of the outer shell 110 of the accessory head 100 can be provided with a connection interface for detachable engagement with the docking interface of the main body 200. Specifically, the output end of the high-voltage power module within the main body 200 is electrically connected to the docking interface. The connection interface of the accessory head 100 adopts a pluggable structure, enabling conduction with the high-voltage power module after engagement with the docking interface. The main controller of the main body 200 controls the start / stop and output parameters of the high-voltage power module, adapting to different beauty needs.

[0046] Reference Figures 1 to 4 The accessory head 100 of the beauty device includes:

[0047] The outer casing 110 has a light outlet 110K;

[0048] The light-emitting component 120 is disposed inside the housing 110. The light-emitting component 120 includes a light-emitting element 121, which is disposed opposite to the light-emitting port 110K and is used to emit light toward the light-emitting port 110K.

[0049] The first circuit board 130 and the second circuit board 140 are disposed inside the housing 110 and arranged opposite each other on both sides of the light-emitting element 121. The first circuit board 130 is provided with a first wiring and the second circuit board 140 is provided with a second wiring.

[0050] One end of the light-emitting element 121 is electrically connected to one of the first wiring and the second wiring, and the other end of the light-emitting element 121 is electrically connected to the other of the first wiring and the second wiring.

[0051] In this embodiment, as Figure 1 and Figure 2 As shown, the housing 110 can be injection molded from ABS engineering plastic to provide a mounting carrier for internal components. Its surface has a light-emitting port 110K, at which a light-transmitting element 170 (such as sapphire) can be installed to protect the internal components and allow light to pass through. The light-emitting component 120 (also referred to as a cosmetic component) is fixed inside the housing 110. The light-emitting component 120 includes a light-emitting element 121 and other supporting structures (such as filters, reflectors, etc.). The light-emitting element 121 includes, but is not limited to, halogen lamps, xenon lamps, etc. Metal pins can be provided at both ends of the light-emitting element 121 for electrical connection with conductive components. The light-emitting element 121 is positioned opposite the light-emitting port 110K, and the emitted light is emitted from the light-emitting port 110K.

[0052] like Figure 3 and Figure 4As shown, the first circuit board 130 and the second circuit board 140 are both fixed inside the housing 110 by screws or clips, and are arranged opposite to each other on both sides of the light-emitting element 121 along the circumferential direction of the light-emitting element 121, forming a symmetrical layout. That is, the first circuit board 130 and the second circuit board 140 are arranged in parallel, and the light-emitting element 121 is located in the structural space between the first circuit board 130 and the second circuit board 140. The first circuit board 130 has a first wiring, and the second circuit board 140 has a second wiring. One of the first wiring and the second wiring is a positive high-voltage line, and the other is a negative high-voltage line, which are used to electrically connect to the two ends of the light-emitting element 121, respectively. Optionally, the electrical connection can be achieved by using a conductive sheet: one end of the conductive sheet is fixed to the wiring area of ​​the circuit board, and the other end is connected to the metal pin of the light-emitting element 121 to ensure the stability of high-voltage transmission.

[0053] When the beauty device is turned on, the main controller of the device body 200 controls the high-voltage power module to output high-voltage current. The current is transmitted through the docking interface and the connection interface to the first wiring of the first circuit board 130 and the second wiring of the second circuit board 140, respectively, and then acts on both ends of the light-emitting element 121, driving the light-emitting element 121 to emit light. The light passes through the light outlet 110K of the outer shell 110 and is emitted, acting on the user's skin to achieve the corresponding beauty function.

[0054] During high-voltage current transmission, since the first and second wirings are arranged on two independent circuit boards, and the two circuit boards are positioned opposite each other on both sides of the light-emitting element 121, the spatial path of the positive and negative high-voltage wirings is significantly extended. Compared with the planar wiring of a traditional single circuit board, the electrical clearance of the wiring in this solution changes from the distance within the circuit board plane to the spatial distance between the two circuit boards. The creepage distance is formed by the wiring path on the circuit board surface and the component assembly gap, which can meet the requirements of relevant safety standards for high-voltage circuits and structurally eliminate the possibility of arc discharge and insulation breakdown.

[0055] In other words, the accessory head 100 of the beauty device in this embodiment adopts a dual-board separate wiring design, which expands the electrical clearance and creepage distance of the positive and negative high voltage lines without increasing the size of the accessory head 100, meets the high voltage safety specifications, and helps to solve the high voltage wiring safety hazards of the miniaturized accessory head 100.

[0056] The structure in which the dual circuit boards and the light-emitting element 121 are combined can be:

[0057] In some embodiments, refer to Figure 4 The first circuit board 130 has a first bracket 10 and a second bracket 20 spaced apart on the side facing the second circuit board 140, and the first bracket 10 is electrically connected to the first wiring.

[0058] The second bracket 20 extends toward the second circuit board 140 and is provided with an electrical plug-in portion 21. The electrical plug-in portion 21 is plugged into the second circuit board 140 and electrically connected to the second wiring.

[0059] The light-emitting element 121 has a first connection end 1211 and a second connection end 1212 that are arranged opposite to each other and have opposite polarities. The first connection end 1211 is fixed on the first bracket 10 and electrically connected to the first wiring through the first bracket 10; the second connection end 1212 is fixed on the second bracket 20 and electrically connected to the second wiring.

[0060] In this embodiment, a first bracket 10 and a second bracket 20 are provided on the first circuit board 130. Both are made of conductive material and are spaced apart and protrude from the side of the first circuit board 130 facing the second circuit board 140. The first bracket 10 is fixed to the first wiring area of ​​the first circuit board 130 by welding or conductive adhesive, thereby achieving an electrical connection with the first wiring.

[0061] The second bracket 20 extends away from the end of the first circuit board 130 and forms an electrical plug-in portion 21 in the direction toward the second circuit board 140. The electrical plug-in portion 21 is a pin-shaped or insert structure. The second circuit board 140 has a corresponding insertion hole. The electrical plug-in portion 21 is adapted to be inserted into the insertion hole and is electrically connected to the second wiring of the second circuit board 140 through conductive contacts in the hole or by soldering.

[0062] The two ends of the light-emitting element 121 are a first connection end 1211 and a second connection end 1212 with opposite polarities. The first connection end 1211 is fixed to the end of the first bracket 10 by snap-fit ​​or welding, and forms a conductive path with the first wiring through the first bracket 10. The second connection end 1212 is installed to the end of the second bracket 20 by the same fixing method, and forms a conductive path with the second wiring through the second bracket 20 and the electrical plug-in part 21.

[0063] The first bracket 10 and the second bracket 20 simultaneously serve the functions of fixing the light-emitting element 121 and conducting electricity, resulting in a compact structure that meets the miniaturization design requirements of the accessory head 100. Furthermore, the second bracket 20 is directly plugged into the second circuit board 140 via the provided electrical connector 21, achieving an electrical connection between the light-emitting element 121 and the wiring on the circuit board. This eliminates the need for additional wiring, simplifies the structure, and improves the overall stability.

[0064] In addition to the above structural forms, it can also be:

[0065] In some embodiments, the first circuit board 130 has a first support 10 on the side facing the second circuit board 140, and the first support 10 is electrically connected to the first wiring; the second circuit board 140 has a second support 20 on the side facing the first circuit board 130, and the second support 20 is electrically connected to the second wiring.

[0066] The light-emitting element 121 has a first connection end 1211 and a second connection end 1212 that are arranged opposite to each other and have opposite polarities. The first connection end 1211 is fixed on the first bracket 10 and electrically connected to the first wiring through the first bracket 10; the second connection end 1212 is fixed on the second bracket 20 and electrically connected to the second wiring.

[0067] In this embodiment, a first bracket 10 is provided on the first circuit board 130. The first bracket 10 is made of conductive material and protrudes from the side of the first circuit board 130 facing the second circuit board 140. The first bracket 10 is fixed to the first wiring area of ​​the first circuit board 130 by soldering or conductive adhesive, thereby achieving an electrical connection with the first wiring.

[0068] The second circuit board 140 is provided with a second bracket 20, which is made of conductive material and protrudes from the side of the second circuit board 140 facing the first circuit board 130. The first bracket 10 is fixed to the second wiring area of ​​the second circuit board 140 by soldering or conductive adhesive, thereby achieving an electrical connection with the second wiring.

[0069] The light-emitting element 121 has a first connecting end 1211 and a second connecting end 1212 with opposite polarities at its two ends. The first connecting end 1211 is fixed to the end of the first bracket 10 by snap-fit ​​or welding, and forms a conductive path with the first wiring through the first bracket 10. The second connecting end 1212 is installed to the end of the second bracket 20 by the same fixing method, and forms a conductive path with the second wiring through the second bracket 20. Along the axial direction of the light-emitting element 121, the first bracket 10 and the second bracket 20 are arranged opposite to each other and at intervals. The first bracket 10 and the second bracket 20 simultaneously undertake the functions of fixing the light-emitting element 121 and conducting electricity, with a compact structural layout that meets the miniaturization design requirements of the accessory head 100.

[0070] In some embodiments, refer to Figures 1 to 3 The beauty device's accessory head 100 also includes:

[0071] The connector 150 is mounted on the housing 110 and located at the same end of the first circuit board 130 and the second circuit board 140. The connector 150 includes a connector base 151 and a plurality of plug terminals 152 passing through the connector base 151. The plurality of plug terminals 152 include at least a first plug terminal 1521 and a second plug terminal 1522. The first plug terminal 1521 is fixed to the first circuit board 130 and electrically connected to the first wiring. The second plug terminal 1522 is fixed to the second circuit board 140 and electrically connected to the second wiring.

[0072] In this embodiment, the connector 150 can be disposed at the rear of the housing 110 (facing the body 200), and located at the same end of the first circuit board 130 and the second circuit board 140, that is, the end side of the two circuit boards facing the rear of the housing 110. The connector base 151 of the connector 150 is made of insulating material, and multiple plug terminals 152 are disposed in the connector base 151, including at least a first plug terminal 1521 and a second plug terminal 1522. Among them, one end of the first plug terminal 1521 can be fixed to a preset pad of the first circuit board 130 by soldering (conducting with the first wiring), and the other end extends along the axial direction of the connector base 151 to form an exposed plug end; one end of the second plug terminal 1522 is fixed to a preset pad of the second circuit board 140 in the same way (conducting with the second wiring), and the other end also forms an exposed plug end; and the first plug terminal 1521 and the second plug terminal 1522 are spaced apart in the connector base 151, and the spatial distance between them meets the high voltage insulation requirements.

[0073] The first plug-in terminal 1521 (corresponding to the first wiring) and the second plug-in terminal 1522 (corresponding to the second wiring) are spaced apart by an insulating connector 151 and are fixed to independent circuit boards respectively. This ensures that the conductive paths of the positive and negative electrodes are physically isolated from the circuit board wiring to the mating terminals, thereby ensuring that the electrical clearance and creepage distance meet safety standards and avoiding the risk of high-voltage breakdown due to insufficient terminal spacing at the connector 150. The connector 150 is integrated into the tail of the housing 110 and located at the same end of the two circuit boards. It can directly connect to the mating interface (such as a socket) of the beauty device body 200 to form a plug-in engagement, making it convenient for users to replace or install the accessory head 100.

[0074] In some embodiments, refer to Figures 1 to 3 The first circuit board 130 is also provided with a third wiring, and the plurality of plug terminals 152 also include a third plug terminal 1523. The third plug terminal 1523 is fixed to the first circuit board 130 and electrically connected to the third wiring. The third plug terminal 1523 is used to transmit a trigger voltage that can make the light-emitting element 121 light up.

[0075] In this embodiment, the first circuit board 130 is further provided with a third wiring, which is a high-voltage trigger signal trace, and can be arranged on the same side as the first wiring and spaced apart. The plurality of plug terminals 152 also includes a third plug terminal 1523, which is made of conductive material and has the same structure as the first and second plug terminals 1522. One end of the third plug terminal 1523 can be soldered to a preset pad on the first circuit board 130 (conductive to the third wiring), and the other end extends axially along the connector base 151 to form an exposed plug end; and the third plug terminal 1523 is spaced apart from the first plug terminal 1521 and the second plug terminal 1522 within the connector base 151, with the spacing meeting the high-voltage isolation requirements. The third wiring receives the high-voltage trigger signal from the beauty device body 200 through the third plug terminal 1523. This high-voltage trigger signal is used to trigger the illumination of the light-emitting element 121, realizing the light-emitting function of the light-emitting element 121. Specifically, one end of the third wiring is electrically connected to the third plug-in terminal 1523, and the other end is electrically connected to the reflector (which has both reflective and conductive properties) of the light-emitting element 121 (such as a lamp tube). When the high-voltage trigger signal is transmitted to the third plug-in terminal 1523, it is conducted to the reflector through the third wiring, so that a high-voltage electric field is formed around the light-emitting element 121. Under the action of the strong electric field, the electrons in the inert gas (xenon, argon, etc.) or mixed metal vapor filled in the light-emitting element 121 are accelerated to gain sufficient kinetic energy and collide with neutral molecules to ionize, generating a large number of free electrons and positive ions (plasma). When the degree of ionization reaches the critical value, a low-resistance arc conduction channel is formed between the electrodes, that is, "arc discharge". At this time, the gas resistance drops sharply, the current rises sharply, and the electrons in the plasma jump and release photons, realizing light emission.

[0076] The third wiring (transmitting the high-voltage trigger signal) and the first wiring (transmitting the high-voltage power supply) are both located on the first circuit board 130 but spaced apart. The signal is transmitted through an independent third connector 1523, which is physically isolated from the first and second connectors 1522 (transmitting the high voltage) within the connector 151. This effectively prevents interference from the high voltage to the low-voltage trigger signal and also prevents the risk of breakdown due to excessive distance between the high and low voltage lines, ensuring circuit safety. Furthermore, the independent separation of the high-voltage power supply (first and second wirings and terminals) and the high-voltage trigger control (third wiring and terminals) makes the circuit layout logic clearer and facilitates later troubleshooting and maintenance.

[0077] In some embodiments, the spacing between the third wiring and the first wiring is D, where D ≥ 8 mm. On the circuit board, the third wiring and the first wiring are arranged at intervals along the plane of the circuit board, and the shortest straight-line distance between them is D, which also satisfies D ≥ 8 mm. Specifically, D can be 8 mm, 9 mm, 10 mm, etc., and can be set according to actual needs. This spacing setting is based on the insulation isolation requirements between high-voltage power supply lines and complies with the safety specifications for high-voltage line spacing. By limiting D ≥ 8 mm, a clear safety threshold is set for the planar spacing between the first wiring and the third wiring, which can effectively avoid electric field interference or insulation breakdown of high-voltage lines to high-voltage trigger signal lines. From a physical dimension perspective, it ensures that the electrical clearance and creepage distance between high and low voltage lines meet mandatory safety standards, eliminating safety hazards caused by insufficient spacing.

[0078] In some embodiments, refer to Figures 1 to 4 , refer to Figure 3 The beauty device's accessory head 100 also includes:

[0079] The detection component is located on the housing 110;

[0080] The second circuit board 140 is also provided with a fourth wiring, and the plurality of plug terminals 152 include a fourth plug terminal 1524. The fourth plug terminal 1524 is fixed to the second circuit board 140 and electrically connected to the fourth wiring. The fourth plug terminal 1524 is electrically connected to the detection component to transmit the detection data of the detection component.

[0081] In this embodiment, the detection component can be fixed to the inner or outer side of the housing 110 by means of snaps, adhesives, or screws, and can be located around the light outlet 110K or on the end face of the housing 110 that contacts the skin, ensuring detection accuracy. Figure 3 As shown, the detection components include, but are not limited to, skin sensor 181 (such as a capacitive sensor), skin color sensor (such as a photodiode module), motion state sensor (such as a gyroscope, accelerometer), etc., used to collect detection data on the user's skin condition or the working state of the accessory head 100.

[0082] The second circuit board 140 also includes a fourth wiring, which is a low-voltage signal trace (adapted for detection data transmission, typically 3V-5V). This fourth wiring can be arranged on the same side as the second wiring but spaced apart. Among the multiple plug-in terminals 152, there is also a fourth plug-in terminal 1524, which is made of conductive material and can be structured like a pin assembly. One end of the fourth plug-in terminal 1524 can be soldered to a preset pad on the second circuit board 140 (conductive to the fourth wiring), while the other end extends axially along the connector base 151 to form an exposed plug-in end. The fourth plug-in terminal 1524 is spaced apart from other plug-in terminals within the connector base 151, with spacing meeting high and low voltage isolation requirements.

[0083] The detection component is electrically connected to the fourth wiring of the second circuit board 140 via wires or conductive connectors (such as flexible ribbon cables). The detection data is transmitted to the main controller of the beauty device body 200 via the fourth wiring and the fourth plug terminal 1524 to realize real-time feedback of detection information.

[0084] The introduction of detection components enables the accessory head 100 to have environmental awareness capabilities. For example, skin contact detection can prevent accidental triggering in non-contact states (such as preventing the light-emitting element 121 from damaging the user or wasting energy), skin color detection can assist the body 200 in adjusting the light emission parameters (such as adjusting the light intensity according to the skin tone of the hair removal device to avoid burns), and movement status detection can determine the usage trajectory (such as prompting even movement to ensure the treatment effect), significantly improving the intelligence level and safety of the beauty device.

[0085] The fourth wiring is integrated into the second circuit board 140, eliminating the need for an additional dedicated testing circuit board. Furthermore, the fourth connector 1524 shares the same connector 151 with other terminals, expanding the testing functionality without increasing the size of the auxiliary head 100, perfectly meeting the requirements of miniaturized design. In addition, testing data is transmitted via the dedicated fourth wiring and fourth connector 1524, physically isolated from the high-voltage power supply lines (first and second terminals) and trigger signal lines (third terminal), preventing interference from high-voltage noise or trigger signals and ensuring the accuracy of data transmission.

[0086] In some embodiments, refer to Figure 4 The first circuit board 130 and the second circuit board 140 are respectively provided with slots 30, and the connector seat 151 is provided with hooks 40 that are adapted to the slots 30, and the hooks 40 are engaged with the slots 30.

[0087] In this embodiment, the edges of the first circuit board 130 and the second circuit board 140 (facing the connector 150) are respectively provided with slots 30, which are openings extending through the thickness of the circuit board. The two side walls of the connector base 151 (corresponding to the positions of the first circuit board 130 and the second circuit board 140) are integrally formed with hooks 40. The hooks 40 are hooks with elastic deformation capability (made of the same material as the connector base 151), with their hook heads facing the slots 30, and the size and shape of the hook heads matching the slots 30. During assembly, the elastic deformation of the hooks 40 causes the hook heads to embed into the slots 30, and the end face of the hook head abuts against the inner sidewall of the slot 30, achieving detachable hook-and-lock connection between the connector base 151 and the first circuit board 130 and the second circuit board 140. The hook structure of the hook 40 and the slot 30 provides bidirectional mechanical constraint for the connector 151 and the circuit board, which can effectively resist axial force during insertion and removal and vibration during use, prevent the connector 151 from shifting relative to the circuit board, ensure that the plug-in terminal and the corresponding circuit board pad / wiring maintain a stable connection, and prevent poor contact or open circuit caused by displacement.

[0088] In some embodiments, refer to Figure 1 The connector 151 has a plurality of protruding isolation portions 1511 on one end face facing away from the first circuit board 130 and the second circuit board 140, and each isolation portion 1511 surrounds the periphery of a plug terminal.

[0089] In this embodiment, the end face of the connector 151 facing away from the first circuit board 130 and the second circuit board 140 (i.e., the end face that mates with the beauty device body 200) is integrally formed with multiple protruding isolation portions 1511. The isolation portions 1511 are made of insulating material (the same material as the connector 151), and have an annular, square, or polygonal protruding structure. Their height is set according to actual needs, and there is a gap between the inner sidewall and the outer peripheral wall of the plug-in terminal.

[0090] like Figure 1 As shown, each isolation section 1511 is independently arranged around the periphery of a plug terminal, so that the exposed part of each plug terminal is located within an independent space formed by the isolation section 1511. Furthermore, a gap is left between adjacent isolation sections 1511, the width of which is not less than the safety distance between the plug terminals. The isolation section 1511, arranged around the periphery of the plug terminal, extends the creepage distance between adjacent terminals through a physical protrusion structure (changing the straight-line distance between terminals to the bypass distance around the outer wall of the isolation section 1511), while also increasing the spatial electrical clearance (the height of the isolation section 1511 increases the three-dimensional spacing). This effectively avoids the risk of short circuits and arc discharges caused by moisture, dust adhesion, or accidental contact during the connection process, thus improving safety.

[0091] In some embodiments, refer to Figure 2 and Figure 3 The beauty device's accessory head 100 also includes:

[0092] The middle shell 160 is located inside the outer shell 110 and covers the light-emitting component 120. The middle shell 160 is provided with a clearance opening opposite to the light-emitting port 110K.

[0093] The first circuit board 130 and the second circuit board 140 are respectively located on the two opposite outer sides of the middle shell 160.

[0094] In this embodiment, the middle shell 160 can be a spliced ​​frame structure, located inside the outer shell 110 and fixed to the inner wall of the outer shell 110 by means of buckles or screws. The interior of the middle shell 160 forms a receiving cavity, in which the light-emitting component 120 is completely housed, achieving positioning and protection of the light-emitting component 120. The front end of the middle shell 160 (corresponding to the side of the light-emitting port 110K of the outer shell 110) is provided with a clearance opening. The shape and size of the clearance opening are adapted to the light-emitting end of the light-emitting component 120, and the clearance opening is coaxially aligned with the light-emitting port 110K of the outer shell 110, ensuring that the light emitted by the light-emitting component 121 can pass through the clearance opening and the light-emitting port 110K without obstruction and act on the skin.

[0095] The first circuit board 130 and the second circuit board 140 are respectively fixed to the two opposite outer sides of the middle shell 160 by means of clips, screws, or thermally conductive adhesive, and the two circuit boards are tightly attached to the outer sides of the middle shell 160. The edges of the circuit boards are adapted to the contour of the middle shell 160, forming an assembly structure of "middle shell 160 in the center and double boards symmetrically clamped". After assembly, the first connecting end 1211 and the second connecting end 1212 of the light-emitting component 121 are electrically connected to the bracket / wiring on the corresponding circuit board through the pre-set clearance holes of the middle shell 160. The structure of the middle shell 160 covering the light-emitting component 120 can form a physical isolation barrier between the light-emitting component 120 and the circuit board, reducing the heat generated by the light-emitting component 120 during operation and reducing the conduction of heat to the circuit board. In addition, the middle shell 160 can also buffer the impact of external forces on the outer shell 110, protecting the internal precision components from damage.

[0096] In some embodiments, refer to Figure 2 and Figure 5 A light-transmitting element 170 is installed at the light outlet 110K, and the light-emitting component 120 also includes:

[0097] The filter element 122 is located between the light-emitting element 121 and the light-transmitting element 170;

[0098] A reflector 123 is mounted on the side of the light-emitting element 121 that is away from the light outlet 110K. The reflector 123 is used to reflect the light projected onto it toward the light outlet 110K.

[0099] In this embodiment, a light-transmitting element 170 is detachably or fixedly mounted at the light outlet 110K of the outer shell 110. The light-transmitting element 170 is made of a high-transmittance insulating material (such as high-transmittance PC, quartz glass, or sapphire), and its shape is adapted to the light outlet 110K. It is fixed to the outer shell 110 by means of snap-fit, adhesive, etc., and is used to protect the internal light-emitting component 120 and allow effective light to pass through. The filter element 122 is a sheet-like or arc-shaped structure (the material can be optical filter glass or PET filter film), which is disposed between the light-emitting component 121 and the light-transmitting element 170, and is fixed by the limiting protrusion or snap-fit ​​of the middle shell 160. Its filtering band is adapted to the beauty function and is used to filter the light emitted by the light-emitting component 121 to obtain light of a specific wavelength. The reflector 123 can be a reflector with an arc shape, covering the non-light-emitting side of the light-emitting element 121, so as to reflect the light projected by the light-emitting element 121 in the direction away from the light-emitting port 110K to the side of the light-emitting port 110K.

[0100] This utility model embodiment also proposes a beauty device, see reference Figure 6 The beauty device includes a main body 200 and an auxiliary head 100 as described in the foregoing embodiments.
