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.

[0032] Reference Figure 1 and Figure 2 The utility model proposes a beauty instrument, including a shell 1, a light emitting part 2 and a light shield 3. The shell 1 is provided with a light outlet 10, the light emitting direction of the light emitting part 2 is toward the light outlet 10, the light shield 3 is located between the light emitting part 2 and the shell 1, and the light shield 3 surrounds the light emitting part 2 in the non-light emitting direction.

[0033] In this embodiment, the light shield 3 is located between the light emitting component 2 and the housing 1, and surrounds the non-light emitting direction of the light emitting component 2. When the light emitting component 2 emits light, the light is emitted in the light emitting direction of the light outlet 10, but at the same time, the light emitted by the light emitting component 2 will also diverge in other directions, and the divergent light direction is the non-light emitting direction of the light emitting component. The setting of the light shield 3 can block the light scattered from the non-light emitting direction of the light emitting component 2 in the light shield 3, and to a certain extent prevent the light emitted by the light emitting component 2 in the non-light emitting direction from passing through the housing 1, thereby reducing the possibility of light leakage from the housing 1.

[0034] Specifically, when the beauty device is started, the light emitting part 2 starts to emit light. The light emitting direction of the light emitting part 2 is toward the light outlet 10, and the light is irradiated onto the human skin through the light outlet 10 to achieve a therapeutic effect. At the same time, the light in the non-light emitting direction of the light emitting part 2 is surrounded by the light shield 3, and the light shield 3 blocks the light in the non-light emitting direction of the light emitting part 2 from passing through the housing to a certain extent, thereby reducing the probability of light leakage from the housing of the beauty device.

[0035] By setting the light shield 3, the probability of light leakage from the housing of the phototherapy beauty instrument can be effectively reduced, and the appearance of the beauty instrument can be improved. In addition, since the light escape is reduced, the possibility of light pollution is also reduced, so that the user can get a better experience during the beauty process.

[0036] In general, the beauty instrument of the present application is provided with a shell 1, a light emitting part 2 and a light shield 3. A light outlet 10 is provided on the shell 1. The light emitting part 2 emits light in a direction toward the light outlet 10. The light shield 3 is located between the light emitting part 2 and the shell 1, and surrounds the non-light emitting direction of the light emitting part 2. When the beauty instrument is started, the light emitting part 2 emits light, wherein the light in the light emitting direction is irradiated onto the skin through the light outlet 10 to achieve a therapeutic effect, while the light in the non-light emitting direction is blocked by the light shield 3, thereby reducing the occurrence of light leakage from the shell. The overall effect is to improve the appearance and light utilization efficiency of the beauty instrument, while reducing the risk of light pollution.

[0037] Reference Figure 2 and Figure 3 In some embodiments, a first air duct 4 is constructed between the housing 1 and the light-emitting component 2 , and at least a portion of the light shield 3 is located between the first air duct 4 and the light-emitting component 2 .

[0038] In this embodiment, the first air duct 4 is designed to provide a heat dissipation channel for the light emitting element 2 to prevent the light emitting element 2 from overheating due to long-term operation. However, the existence of the first air duct 4 may cause light in a non-light-emitting direction to leak out from the first air duct 4, which may affect the appearance and phototherapy effect of the beauty instrument to a certain extent.

[0039] Therefore, a light blocking cover is arranged between the shell and the light-emitting component, and at least a part of the light blocking cover 3 is located between the first air duct 4 and the light-emitting component 2. This part can block the light emitted by the light-emitting component 2 in a non-light-emitting direction from leaking outward from the first air duct 4, so as to reduce the light leakage probability of the shell 1 and improve the light utilization efficiency of the beauty instrument to a certain extent.

[0040] When the beauty instrument is started, the light emitting element 2 emits light and generates heat during operation. The first air duct 4 provides a heat dissipation channel for the light emitting element 2. The heat generated by the light emitting element 2 can be dissipated by ventilation through the first air duct 4 to ensure the normal operation of the light emitting element 2. At the same time, the light shield 3 is located between the first air duct 4 and the light emitting element 2, preventing the light emitted by the light emitting element 2 in a non-light emitting direction from penetrating from the first air duct 4, thereby reducing the probability of light leakage.

[0041] The present application achieves the effect of heat dissipation for the light-emitting component 2 by setting the first air duct 4. At the same time, by setting the light shield 3 so that at least part of it is located between the first air duct 4 and the light-emitting component 2, the light shield 3 can effectively reduce the light escaping from the first air duct 4, thereby improving the appearance and treatment effects of the beauty instrument.

[0042] Reference Figures 1 to 4 In some embodiments, the shell 1 proposed in the embodiment of the utility model includes a first shell 11 and a second shell 12, the second shell 12 is configured with a connecting port 120, the light-emitting component 2 is arranged on the first shell 11, and one end of the light shield 3 extends into the connecting port 120 to connect to the inner wall of the second shell 12; the other end of the light shield 3 is connected to the first shell 11, and the outer wall of the light shield 3 is spaced from the inner wall of the second shell 12 to form a first air duct 4.

[0043] In this embodiment, the shell 1 includes a first shell 11 and a second shell 12. The second shell 12 is provided with a connecting port 120, and the light-emitting component 2 is arranged on the first shell 11. One end of the light shield 3 extends into the connecting port 120 of the second shell 12 and is connected to the inner wall of the second shell 12; the other end of the light shield 3 is connected to the first shell 11, and a first air duct 4 is formed between the outer wall of the light shield 3 and the inner wall of the second shell 12.

[0044] During installation, one end of the light shield 3 can be inserted into the connection port 120 of the second shell 12 and connected to the inner wall of the second shell 12, so that the light shield 3 is connected to the second shell 12. Then, the other end of the light shield 3 is connected to the first shell 11, completing the connection between the second shell 12, the light shield 3 and the first shell 11 in the beauty instrument of the present application.

[0045] Through the above design, the connection between the light shield 3, the first shell 11 and the second shell 12 is ensured. At the same time, the first air duct 4 formed between the light shield 3 and the second shell 12 provides an effective heat dissipation channel for the light-emitting element 2, which helps to maintain the normal working state of the light-emitting element 2. In addition, the air inlet of the first air duct 4 is arranged adjacent to the first shell 11. When the first shell 11 is attached to the skin, the outside air enters the first air duct 4 from the air inlet of the first air duct 4, while also accelerating the air flow on the skin surface, which also has a certain heat dissipation effect on the user's skin. Overall, the stability and heat dissipation effect of the beauty instrument are improved, and the user experience is enhanced.

[0046] In some embodiments, the inner wall of the second housing 12 and the light shield 3 can be connected by screws, by providing a threaded hole on one of the inner wall of the second housing 12 and the light shield 3, providing a structure that matches the threaded hole on the other, and then connecting the two by screws. Those skilled in the art can also design according to actual needs, such as using a buckle or other structure for detachable connection.

[0047] Reference Figure 3 and Figure 4 In some embodiments, the connection port 120 provided in the embodiment of the present invention is set to be contracted toward the center of the second shell 12, and / or

[0048] The inner wall of the second shell 12 includes a reflective surface 111 . The reflective surface 111 is connected to the connection port 120 . The reflective surface 111 is disposed toward the inner center of the second shell 12 .

[0049] In the present embodiment, the connection port 120 is set to be contracted toward the center of the second shell body, so that one end of the second shell body 12 where the connection port 120 is set can be formed with an edge portion surrounding the connection port 120, which can effectively limit the scattering of light inside the second shell body 120, and to a certain extent prevent the light emitted by the light-emitting component 2 in a non-light-emitting direction from leaking from the first air duct 4. When the light in the non-light-emitting direction is irradiated onto the inner wall of the edge portion, the refracted light will be directed toward the interior of the second shell body 120 instead of the first air duct 4. Therefore, the above-mentioned setting of the present embodiment is beneficial to a certain extent in preventing the light emitted by the light-emitting component 2 in a non-light-emitting direction from leaking from the first air duct 4.

[0050] In some embodiments, a reflective surface can be provided inside the second housing 12 to reflect light and guide it toward the use area of ​​the beauty instrument, thereby increasing the utilization efficiency of light and improving the phototherapy effect of the beauty instrument. By providing the reflective surface 111 on the inner wall of the second housing, the reflected light is effectively guided to the light outlet 10, thereby improving the phototherapy effect.

[0051] It should be noted that the above two settings can be selected either one or both, and they can also be set at the same time without interfering with each other.

[0052] In some embodiments, a reflective surface may be produced by attaching a reflective material to the inner wall of the second housing 12 .

[0053] The embodiment of the present application limits the scattering of light by setting the contraction of the connection port 120, and prevents the light of the light emitting element 2 in the non-light emitting direction from leaking out of the first air duct 4. A reflector can also be set on the inner wall of the second shell 12 to reflect the light to the inner center of the second shell 12, or multiple reflective surfaces can be set to reflect the light projected on the reflective surface 111 to the light outlet 10, so as to achieve the effect of preventing light leakage and focusing the light.

[0054] Reference Figure 3 and Figure 5 In some embodiments, the beauty instrument proposed in the embodiment of the utility model also includes a heat dissipation component 5, which is at least partially disposed inside the second shell 12, and the heat dissipation component 5 is connected to the first air duct 4, and the heat dissipation component 5 is used to dissipate heat for the light-emitting component 2.

[0055] In this embodiment, the heat dissipation component 5 is at least partially disposed inside the second housing 12 and can be communicated with the first air duct 4. The working principle of the heat dissipation component 5 is that the heat dissipation component 5 is at least partially located inside the second housing and communicated with the first air duct 4, so that the heat dissipation component 5 can effectively use the first air duct 4 to dissipate heat. Specifically, when the light-emitting element 2 generates heat during operation, the heat dissipation component 5 exchanges airflow with the external environment of the beauty instrument through the first air duct 4, thereby promoting the dissipation of heat.

[0056] The working process of the heat dissipation component 5: the light-emitting component 2 starts to work and generate heat after being started. The heat dissipation component 5 is located inside the second shell 12 and is connected to the first air duct 4. The heat dissipation component 5 can exchange air intake and air outlet with the outside of the beauty instrument through the first air duct 4 to exchange the air flow inside and outside the beauty instrument, thereby exchanging the hot air flow generated by the internal light-emitting component 2 with the external normal temperature air flow, thereby effectively dissipating heat and ensuring the normal operation of the light-emitting component 2.

[0057] The effects of the heat dissipation component are:

[0058] First, the stability of the beauty instrument is improved: the heat dissipation component 5 effectively dissipates heat, which can prevent the light-emitting element 2 from being damaged due to overheating, thereby improving the stability and reliability of the beauty instrument.

[0059] Second, the service life of the light emitting element 2 is extended: effective heat dissipation can reduce the operating temperature of the light emitting element 2, extend its service life, reduce the frequency of maintenance and replacement, and reduce the cost of use.

[0060] Third, improve safety: Effective heat dissipation can avoid safety hazards caused by overheating and ensure the user's safe use experience.

[0061] In summary, the present embodiment improves the performance and stability of the beauty instrument by disposing the heat dissipation component 5, ensures the normal operation of the light-emitting component, and enhances the user experience.

[0062] Reference Figure 3 and Figure 5 In some embodiments, the heat dissipation assembly 5 proposed in the embodiments of the utility model includes a heat dissipation fan 51, and the second shell 12 is provided with a third air vent 113, and the third air vent 113 runs through the inner wall and the outer wall of the second shell 12. The air inlet end of the heat dissipation fan 51 is connected to the first air duct 4, and the air outlet end of the heat dissipation fan 51 is connected to the third air vent 113. The heat dissipation fan 51 is used to generate airflow and dissipate heat for the light-emitting component.

[0063] In this embodiment, the heat dissipation fan 51 can generate airflow by rotating blades. When the beauty instrument is started, the heat dissipation fan 51 starts to rotate, and air can be taken in through the first air duct 4 from the air inlet end of the heat dissipation fan 51, and exhausted to the outside of the beauty instrument through the third vent 113 from the air outlet end of the heat dissipation fan 51. The air intake and exhaust of the heat dissipation fan 51 form an airflow, which passes through the space around the light-emitting component 2, contacts the surface of the light-emitting component 2, and takes away the heat generated by the light-emitting component 2 during operation and discharges it to the outside of the beauty instrument.

[0064] The provision of the heat dissipation fan 51 can effectively reduce the operating temperature of the light emitting element 2 and improve the heat dissipation efficiency of the beauty instrument. The heat dissipation effect is achieved by continuously sending air into the vicinity of the light emitting element 2 and discharging the hot air generated by the light emitting element 2. The heat dissipation fan ensures the stability and performance of the beauty instrument, can extend the service life of the light emitting element 2, and also improves the working efficiency and reliability of the beauty instrument.

[0065] In some embodiments, the first air duct 4 can be divided into an air inlet duct and an air outlet duct in the structural design inside the second shell 12, and then the air inlet end of the heat dissipation fan 51 is connected to the air inlet duct, and the air outlet end is connected to the air outlet duct, so as to achieve the effect of the heat dissipation fan 51 dissipating heat to the light-emitting component 2 through the first air duct 4. Those skilled in the art can make settings according to actual needs.

[0066] Reference Figure 3 and Figure 5In some embodiments, the heat dissipation assembly 5 proposed in the embodiment of the utility model also includes a wind cover 52, and a first opening 30 is provided at one end of the light shield 3 extending into the connecting port 120, one end of the wind cover 52 is accommodated in the second shell 12, and the other end of the wind cover 52 extends into the first opening 30, and the wind cover 52 is provided with a second opening 521 and a third opening 522, and a second air duct 520 is constructed between the second opening 521 and the third opening 522, the heat dissipation fan 51 and the light-emitting component 2 are arranged in the second air duct 520, the second air duct 520 is connected to the first air duct 4 through the second opening 521 and the first opening 30, and the second air duct 520 is connected to the third vent 113 through the third opening 522.

[0067] In this embodiment, the wind cover 52 is constructed with a second opening 521, a third opening 522 and a second air duct 520. The second air duct 520 is formed between the second opening 521 and the third opening 522. The heat dissipation fan 51 and the light-emitting component 2 are arranged in the second air duct 520. When the beauty instrument is working, the light-emitting component 2 emits light and generates heat, and the heat dissipation fan 51 starts to work. Under the action of the heat dissipation fan 51, external air can enter the second air duct 520 through the first opening 30 and the second opening 521 of the wind cover 52 for use by the heat dissipation fan 51. The heat dissipation fan 51 continuously introduces fresh air into the vicinity of the light-emitting component 2, and discharges hot air out of the third vent 113 through the second air duct 520 and the third opening 522, thereby effectively enhancing the heat dissipation effect on the light-emitting component 2.

[0068] That is, when the heat dissipation fan 51 is working, the air inlet end of the heat dissipation fan 51 inhales air, and the air outside the beauty instrument passes through the first air duct 4, the first opening 30, and the second opening 521, and then enters the heat dissipation fan 51 from the air inlet end, and then the heat dissipation fan 51 discharges the gas, and the discharged gas passes through the third opening 522 and the third vent 113 and is discharged to the outside of the beauty instrument.

[0069] In some embodiments, the air cover 52 structurally surrounds the light emitting element 2 , and to a certain extent blocks the light of the light emitting element 2 in non-light emitting directions from leaking out from the first air duct 4 or the third vent 113 .

[0070] In some embodiments, the third vent 113 may be a vent hole structure opened on the second shell 12, and the number of vent holes may be set according to actual needs. Similarly, those skilled in the art may design the vent structure according to actual needs.

[0071] The design of the wind shield 52 in the embodiment of the present application helps to increase the speed of air flow and determine the direction of air flow, thereby improving the working efficiency of the heat dissipation fan, thereby more effectively removing the heat of the light-emitting component, ensuring the stability and performance of the beauty instrument. To a certain extent, it blocks the light of the light-emitting component 2 in the non-light-emitting direction from leaking out of the first air duct 4 or the third vent 113.

[0072] Reference Figure 2 In some embodiments, the inner wall of the second shell 12 proposed in the embodiment of the utility model is protrudingly provided with a first guide rib 114 and a second guide rib 115, and the first guide rib 114 and the second guide rib 115 are arranged at intervals, and a third air duct 116 is formed between the inner wall of the second shell 12, the first guide rib 114 and the second guide rib 115, and the third air duct 116 is connected to the third opening 522 and the third vent 113, and the first guide rib 114 and the second guide rib 115 are used to separate the third air duct 116 from the first air duct 4.

[0073] In this embodiment, the first guide rib 114 and the second guide rib 115 isolate the third air duct 116 and the first air duct 4. When the heat dissipation fan 51 is working, the gas at the air inlet and outlet ends of the heat dissipation fan 51 will not mix, thereby maintaining the working effect of the heat dissipation fan 51.

[0074] When the beauty instrument is started, external air enters the second air duct 520 through the first opening 30 and the second opening of the wind cover 52, and is sucked by the air inlet end of the heat dissipation fan 51. The airflow blown out by the air outlet end of the heat dissipation fan 51 is discharged to the third vent 113 through the third air duct 116, and is directly discharged to the outside of the second housing 12 from the third vent 113. The first guide rib 114 and the second guide rib 115 are provided to effectively isolate the inlet airflow and the outlet airflow required by the heat dissipation fan 51, prevent the airflow from mixing, and to a certain extent avoid the probability of the problem of reduced heat dissipation efficiency caused by airflow mixing.

[0075] At the same time, the first guide rib 114 and the second guide rib 115 can also block part of the light in the non-light emitting direction of the light emitting element 2, so that the light in the non-light emitting direction of the light emitting element 2 is not easy to penetrate outward from the third vent 113.

[0076] The embodiments of the present application achieve the following beneficial effects through the above configuration:

[0077] First, airflow isolation: the first guide rib 114, the second guide rib 115 and the third air duct 116 effectively isolate the inlet airflow and the outlet airflow required by the heat dissipation fan, and prevent the airflow from mixing. This ensures the working effect of the heat dissipation fan 51, avoids the mixing of the gas at the inlet end and the outlet end, and thus improves the heat dissipation efficiency.

[0078] Second, light blocking: the first guide rib 114 and the second guide rib 115 can also block the light in the non-light-emitting direction of some light-emitting parts, making it difficult for the light to penetrate outward from the third vent 113, which helps to reduce the interference of external light, maintain the comfort of the use environment, and enhance the aesthetics of the product.

[0079] Third, airflow guidance: when the beauty instrument is started, external air enters the second air duct 520 through the first opening 30 and the second opening 521 of the wind cover 52, and is sucked by the heat dissipation fan 51. Then the air outlet of the heat dissipation fan 51 discharges the air through the third air duct 116 to the third vent 113. The multi-air duct design effectively guides the air flow, ensures the normal operation of the heat dissipation system, and maintains a good heat dissipation effect.

[0080] Reference Figure 5 In some embodiments, the wind hood 52 proposed in the embodiments of the utility model is constructed with a first cavity 523 and a second cavity 524, the first cavity 523 and the second cavity 524 are connected to each other to form a second air duct 520, the second opening 521 is connected to the first cavity 523, and the light-emitting component 2 is arranged in the first cavity 523; the third opening 522 is connected to the second cavity 524, and the heat dissipation fan 51 is arranged in the second cavity 524; the air inlet end of the heat dissipation fan 51 is connected to the first cavity 523, and the air outlet end of the heat dissipation fan 51 is connected to the third vent 113.

[0081] In this embodiment, the first cavity 523 and the second cavity 524 are connected to each other to form a second air duct 520. The second opening 521 is connected to the first cavity 523, and the third opening 522 is connected to the second cavity 524, forming a flow channel for airflow.

[0082] When the beauty instrument is started, the heat dissipation fan 51 starts to dissipate heat as the light-emitting component 2 works. The air inlet end of the heat dissipation fan 51 can draw air from the outside through the second opening 521, the first opening 30 and the first air duct 4. The gas enters the first cavity 523 through the second opening 521. After passing around the light-emitting component 2, the air flow is sucked in by the air inlet end of the heat dissipation fan 51, and is discharged from the air outlet end through the third opening 522 to the third vent 113 outside the second shell 12.

[0083] The structure of the first cavity 523 and the second cavity 524 first forms an air duct structure for the heat dissipation airflow to flow, and at the same time, the heat dissipation fan 51 can be separated from the light-emitting component 2 to prevent the working heat of the heat dissipation fan 51 from affecting the light-emitting component 2.

[0084] In some embodiments, the heat dissipation method of the heat dissipation fan 51 can also be: the air inlet end of the heat dissipation fan 51 is connected to the third vent 113, the heat dissipation fan 51 draws air to the outside of the second housing 12 through the third vent 113, and then the air outlet end of the heat dissipation fan 51 is arranged toward the light-emitting element 2, and the air outlet end of the heat dissipation fan 51 blows out gas to directly dissipate the heat of the light-emitting element 2, and then the gas carrying the heat of the light-emitting element 2 is discharged from the first opening 30 and the first air duct 4 to the outside of the second housing 12. Those skilled in the art can design according to actual needs.

[0085] Reference Figure 3 and Figure 6 In some embodiments, the beauty instrument proposed in the embodiment of the utility model further includes a heat sink 6, which is disposed in the first cavity 523. A receiving groove is configured on a side of the heat sink 6 facing the light-emitting component 2, and at least a portion of the light-emitting component 2 is received in the receiving groove.

[0086] In this embodiment, the heat sink 6 is usually made of a material with high thermal conductivity (such as aluminum or copper) to increase the surface area in contact with the air, thereby improving the heat dissipation efficiency. In the present application, the heat sink 6 is installed in the first cavity 523 and is arranged close to the light emitting element 2. The heat sink 6 is configured with a receiving groove on one side facing the light emitting element 2. The receiving groove can surround at least part of the light emitting element 2, so that heat can be absorbed from the light emitting element 2 more directly and more effectively. At the same time, the part of the light emitting element 2 surrounded by the receiving groove also has the effect of blocking the light emitted by the light emitting element 2 in the non-light emitting direction in the direction away from the light outlet 10.

[0087] When the beauty instrument is started, the light-emitting element 2 starts to work and generates heat. Since a part of the light-emitting element 2 is accommodated in the accommodating groove of the heat sink 6, the heat sink 6 absorbs the heat generated by the light-emitting element 2 when it is working. The heat is then conducted in the first cavity 523 through the heat sink 6. Due to the air flow generated by the heat dissipation fan 51, the heat dissipated from the light-emitting element 2 by the heat sink 6 is taken away by the airflow generated by the heat dissipation fan 51, thereby reducing the temperature of the light-emitting element 2.

[0088] The provision of heat sinks significantly improves heat dissipation efficiency, which has several direct benefits: first, more effective heat dissipation can prevent the light-emitting components from overheating, thereby protecting the light-emitting components and extending their service life; second, maintaining the light-emitting components at a lower temperature can improve their performance stability and efficiency; finally, the reliability and safety of the overall equipment are also improved.

[0089] Reference Figure 6 In some embodiments, the beauty instrument proposed in the embodiment of the utility model further includes a reflector 8, which is attached to the receiving groove, and is used to reflect light projected on the reflector in a non-light-emitting direction to the light outlet 10.

[0090] In this embodiment, the reflector 8 is generally an optical element, such as a reflector or a high-reflectivity film, and its purpose is to reflect the light generated by the light-emitting element 2, especially those lights that are directed in non-light-emitting directions. The reflector 8 is attached to the receiving groove on the heat sink 6 to maximize its reflection efficiency.

[0091] When the beauty instrument is turned on and the light emitting element starts to emit light, the light in the light emitting direction directly irradiates the skin through the light emitting port. After the light in the non-light emitting direction toward the reflector 8 is projected onto the reflector 8, the reflector 8 reflects it to the light emitting port 10. The setting of the reflector 8 also prevents part of the light in the non-light emitting direction from leaking out of the air duct to a certain extent.

[0092] By using reflective parts, the light energy utilization rate of the beauty instrument is significantly improved, which not only enhances the phototherapy effect and provides more uniform and intense irradiation, but also improves energy efficiency, thereby reducing energy consumption and increasing the consistency and effectiveness of the treatment effect. In addition, higher light utilization means that lower-power light-emitting parts can be used to achieve the same therapeutic effect, thereby reducing the heat load of the equipment and further improving overall safety and comfort.

[0093] Reference Figure 5 In some embodiments, the beauty instrument proposed in the embodiment of the utility model further includes a main control circuit board 7, one end of the main control circuit board 7 is accommodated in the second shell 12, and the other end of the main control circuit board 7 extends into the first cavity 523 through the first opening 30 and the second opening 521. The light-emitting component 2 includes a main body 21 and connecting parts 22 arranged at both ends of the main body 21. The main body 21 is accommodated in the accommodating groove, and the two connecting parts 22 are exposed in the accommodating groove. One end of the main control circuit board 7 extending into the first opening 30 is connected to the two connecting parts 22.

[0094] In this embodiment, the main control circuit board 7 generally includes a control circuit, a power supply module and a possible communication interface, which is used to manage various electronic functions of the beauty instrument. One end of the main control circuit board 7 is accommodated and installed in the second shell 12, and the other end extends into the first cavity 523 through the first opening 30 and the second opening 521, and is directly connected to the connection portion 22 of the light-emitting element 2.

[0095] When the beauty instrument is started, the user can control the main control circuit board 7 through the control interface (which may include buttons or a touch screen) of the second housing 12. After receiving the start command, the main control circuit board 7 provides current to the light-emitting element 2 through its internal circuit to control the operation of the light-emitting element 2. The main control circuit board 7 may also be responsible for adjusting the current intensity or controlling the light-emitting mode to meet different treatment needs.

[0096] Reference Figure 5 In some embodiments, the beauty instrument proposed in the embodiment of the utility model also includes a reflector 9; the reflector 9 is arranged on the inner wall of the first cavity 523 and is arranged toward the two connecting parts 22. The reflector 9 is used to reflect the light projected onto the reflector 9 in a non-light-emitting direction to the light outlet 10.

[0097] In this embodiment, the reflector 9 can be attached to the inner wall of the first cavity 523 and arranged toward the two connecting parts 22 of the light emitting member 2. Since the two connecting parts 22 extend out of the receiving groove, a certain amount of light scattering or light leakage will occur. The function of the reflector 9 is to capture these lights in non-light-emitting directions and reflect them to the light outlet 10 of the beauty instrument, thereby increasing the effective use of light and enhancing the irradiation effect.

[0098] When the beauty instrument is turned on and the light-emitting element 2 starts working, most of the light is emitted directly from the light outlet, but the connecting parts 22 at both ends of the light-emitting element will also release some light, which will be projected onto the inner wall of the first cavity 523. The reflective element 9 can be attached to the inner wall of the first cavity 523 to capture these scattered lights and reflect them to the light outlet 10. The angle and surface treatment of the reflective element can effectively reflect the light toward the light outlet 10. The reflective element 9 can be made of the same material as the aforementioned reflective element 8.

[0099] The setting of the reflector 9 not only improves the light-emitting effect of the beauty instrument of the present application to a certain extent, but also because the reflector 9 reflects the light in the non-light-emitting direction projected on the reflector 9 to the light outlet 10, it plays a role in preventing the light in the non-light-emitting direction from leaking out of the shell 1 to a certain extent.
