Skin care device

Abstract

This utility model discloses a skin care device, which includes a housing, a light-emitting component, and a first heat dissipation component, both of which are housed within the housing. The housing has an air inlet and an air outlet. The first heat dissipation component includes a heat-conducting part and a heat-dissipating part. The heat-conducting part is connected to the light-emitting component, and the heat-dissipating part is located between the air inlet and the air outlet. External air can enter the housing through the air inlet, exchange heat with the heat dissipation part, and then exit the housing through the air outlet. In this design, the first heat dissipation component directly contacts the light-emitting component, resulting in higher heat conduction efficiency for the light-emitting component compared to air heat exchange. This leads to higher heat dissipation efficiency for the light-emitting component. Furthermore, the residence time of the heat exchange airflow within the housing is shorter, resulting in a lower temperature rise and a greater temperature difference between the heat exchange airflow and the heat dissipation part, thus further enhancing heat exchange efficiency. Simultaneously, the hot airflow after heat exchange with the heat dissipation part can be quickly exited into the housing, further improving the heat dissipation efficiency for the light-emitting component.

Description

Technical Field

[0001] This utility model relates to the field of skin care, and in particular to a skin care device. Background Technology

[0002] The skin care device includes a light-emitting component that generates treatment light capable of performing at least one of the following: skin whitening, skin care, or hair removal. The light-emitting component generates considerable heat during operation, requiring heat dissipation to prevent overheating and disruption of normal function. In related technologies, a fan assembly drives a cooling airflow to exchange heat with the light-emitting component. This cooling airflow flows along a predetermined path within the skin care device. However, this winding and tortuous flow path results in both a long path and insufficient heat transfer, leading to low heat exchange efficiency and consequently low heat dissipation efficiency for the light-emitting component.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] In the technical solution of this utility model, the skin care device includes a housing, a light-emitting component, and a first heat dissipation component, both of which are disposed within the housing. The housing has an air inlet and an air outlet. The first heat dissipation component includes a heat-conducting part and a heat-dissipating part. The heat-conducting part is connected to the light-emitting component, and the heat-dissipating part is disposed between the air inlet and the air outlet. External air can enter the housing through the air inlet, exchange heat with the heat dissipation part, and then exit the housing through the air outlet. In this design, a first heat dissipation component is installed to direct the heat from the light-emitting component to the vicinity of the air inlet near the housing (i.e., directing the heat from the light-emitting component from the heat-conducting part to the heat dissipation part). Compared to a design where the air entering the housing through the air inlet is directed to the light-emitting component, this design has two advantages: First, the first heat dissipation component directly contacts the light-emitting component, resulting in higher heat conduction efficiency for the light-emitting component compared to air heat exchange, thus leading to higher heat dissipation efficiency. Second, the heat exchange airflow entering the housing through the air inlet exchanges heat with the closer heat dissipation part, rather than with the farther light-emitting component. This results in a shorter flow path for the heat exchange airflow, a shorter residence time of the heat exchange airflow within the housing, a lower temperature rise of the heat exchange airflow, and a greater temperature difference with the heat dissipation part, thus achieving higher heat exchange efficiency.

[0032] Furthermore, in this solution, the heat dissipation unit is located between the air inlet and the air outlet, allowing the airflow after heat exchange with the heat dissipation unit to be directly discharged from the air outlet. Compared to related technologies where the heat exchange airflow after heat exchange with the light-emitting component is discharged along a curved path to the air outlet, in this solution, the hot airflow after heat exchange with the heat dissipation unit can be quickly discharged into the housing, thereby further improving the heat dissipation efficiency for the light-emitting component. Simultaneously, in this solution, the airflow introduced into the housing through the air inlet, after heat exchange with the heat dissipation unit, and discharged from the housing through the air outlet experiences less resistance and smoother flow, thus improving heat exchange efficiency while reducing wind noise.

[0051] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] The skin care device includes a light-emitting component that generates treatment light capable of performing at least one of the following: skin whitening, skin care, or hair removal. The light-emitting component generates considerable heat during operation, requiring heat dissipation to prevent overheating and disruption of normal function. In related technologies, an air inlet is located at the rear of the light-emitting component. An air supply component drives a cooling airflow into the skin care device through the inlet. The cooling airflow then moves forward and exchanges heat with the light-emitting component. The cooling airflow flows laterally from one side of the light-emitting component to the other and exits through an air outlet. To avoid other components within the skin care device, the cooling airflow path is winding and tortuous. This results in a long flow path and insufficient heat transfer, leading to low heat exchange efficiency and consequently low heat dissipation efficiency for the light-emitting component.

[0054] In view of this, see Figures 1-7 In some embodiments of this application, a skin care device 10 is provided, which can improve the heat dissipation effect on the light-emitting component 200. Specifically, the skin care device 10 includes a housing 100, a light-emitting component 200, and a first heat dissipation component 300.

[0055] See Figures 1-3 The housing 100 defines a receiving cavity 140. The housing 100 has a light-emitting port 150 communicating with the receiving cavity 140, used to emit treatment light. The light-emitting port 150 is located at one end of the housing 100. During operation of the skin care device, the user holds the housing 100 and brings the end of the housing 100 with the light-emitting port 150 close to or against the skin to be treated, illuminating the skin with the treatment light to treat it. For ease of description, see [reference needed]. Figures 2-3 The following defines the first direction X, the second direction Y, and the third direction Z based on the position of the light outlet 150. The light outlet 150 is located at one end of the housing 100 along the first direction X. The second direction Y and the third direction Z are two directions that are perpendicular to the first direction X, respectively, and the second direction Y and the third direction Z are perpendicular to each other.

[0056] See Figures 2-3 The housing 100 has an air inlet 180 on one side along the second direction Y, and an air outlet 190 on the other side along the second direction Y. That is to say, the air inlet 180 and the air outlet 190 are located on opposite sides of the housing 100 along the second direction Y. The external heat exchange airflow is introduced into the housing 100 through the air inlet 180, and after the heat exchange airflow absorbs the heat from the light-emitting component 200, it is discharged out of the housing 100 through the air outlet 190.

[0057] The specific structure of the light-emitting component 200 depends on the actual needs; it only needs to be able to generate the light required for skin care. See details... Figure 4 as well as Figure 7 In some embodiments, the light-emitting component 200 may include a light-emitting element 210 and a light guide 220. The light-emitting element 210 generates nursing light, and the light guide 220 guides the nursing light generated by the light-emitting element 210 to the light outlet 150. Specifically, the light-emitting element 210 may include a light-emitting element 212 and a circuit board 211 connected to the light-emitting element 212. The light-emitting element 212 is electrically connected to the circuit board 211, and the circuit board 211 controls the switching and power of the light-emitting element 212 according to the actual working conditions. In this embodiment, the light-emitting element 212 is block-shaped and is a surface light source, and the light generated by the light-emitting element 212 is diffused towards the side facing the light outlet 150. In other embodiments, the light-emitting element 212 may also be tubular, and the light generated by the light-emitting element 212 is diffused in all directions. In this embodiment, in order to concentrate the light generated by the light-emitting element 212 and lead it out of the light outlet 150 to improve the luminous efficiency, a reflector can be provided. The reflector is provided on the side of the light-emitting element 212 away from the light outlet 150, and the reflector is arranged around the side of the light-emitting element 212 away from the light outlet 150, so as to reflect the light emitted by the light-emitting element 212 towards the side away from the light outlet 150 to the housing 100 exiting from the light outlet 150.

[0058] See Figure 4 as well as Figure 7 A light guide 220 is disposed within the receiving cavity 140 and connected to the housing 100. The light guide 220 passes through the light outlet 150 and is used to guide the light generated by the light-emitting element 210 out of the housing 100 through the light outlet 150. The light guide 220 covers the light outlet 150, making it difficult for external foreign objects to enter the housing 100 through the light outlet 150, thus improving the sealing effect of the housing 100. The nursing light generated by the light-emitting element 210 enters the light guide 220 from one end, is conducted through the light guide 220, and finally exits the housing 100 through the light outlet 150. The light guide 220 can be made of a material with high light transmittance and high heat resistance. The high light transmittance of the light guide 220 results in low energy loss after the nursing light is conducted through the light guide 220; the heat resistance of the light guide 220 prevents it from deforming or being damaged after absorbing the energy of the nursing light and heating up. For example, the material of the light guide 220 can be sapphire or quartz.

[0059] See Figures 2-3A first heat dissipation assembly 300 is disposed in the receiving cavity 140. The first heat dissipation assembly 300 includes a heat-conducting part 310 and a heat dissipation part 320 connected to each other. The heat-conducting part 310 is connected to the light-emitting assembly 200 and is used to acquire heat from the light-emitting assembly 200 and conduct the heat to the heat dissipation part 320. The heat-conducting part 310 is used to exchange heat with any component of the light-emitting assembly 200. For example, the heat-conducting part 310 can exchange heat with the light-emitting element 210 of the light-emitting assembly 200 or with the light guide element 220 of the light-emitting assembly 200. See also Figure 3 as well as Figure 4 In this embodiment, the heat-conducting part 310 is attached to the side of the circuit board 211 away from the light-emitting element 212 to directly exchange heat with the circuit board 211. The heat generated by the light-emitting element 212 is directed to the circuit board 211, and the heat of the circuit board 211 is directed to the heat-conducting part 310. The heat-conducting part 310 conducts the heat to the heat dissipation part 320. The heat dissipation part 320 is located between the air inlet 180 and the air outlet 190. The airflow guided from the air inlet 180 to the air outlet 190 can exchange heat with the heat dissipation part 320 located between the air inlet 180 and the air outlet 190, so that the heat of the light-emitting component 200 is finally discharged from the housing 100 by the heat exchange airflow through the air outlet 190.

[0060] The skin care device 10 provided in this embodiment is equipped with a first heat dissipation component 300 to guide the heat of the light-emitting component 200 to the vicinity of the air inlet 180 of the housing 100 (that is, to guide the heat of the light-emitting component 200 from the heat-conducting part 310 to the heat dissipation part 320). Compared with the solution of guiding the air entering the housing 100 from the air inlet 180 to the light-emitting component 200, on the one hand, in this solution, the first heat dissipation component 300 directly contacts the light-emitting component 200, which has a higher heat conduction efficiency for the light-emitting component 200 than air heat exchange, thus the heat dissipation efficiency of the light-emitting component 200 is higher; on the other hand, in this solution, the heat exchange airflow entering the housing 100 from the air inlet 180 exchanges heat with the heat dissipation part 320 which is closer, rather than with the light-emitting component 200 which is farther away. The flow path of the heat exchange airflow is shorter, the residence time of the heat exchange airflow in the housing 100 is shorter, the temperature rise of the heat exchange airflow is lower, and the temperature difference with the heat dissipation part 320 is greater, thus the heat exchange efficiency is higher.

[0061] Furthermore, in this solution, the heat dissipation unit 320 is located between the air inlet 180 and the air outlet 190, allowing the airflow after heat exchange with the heat dissipation unit 320 to be directly discharged from the air outlet 190. Compared to related technologies where the heat exchange airflow after heat exchange with the light-emitting component is discharged along a curved path to the air outlet, in this solution, the hot airflow after heat exchange with the heat dissipation unit 320 can be quickly discharged into the housing 100, thereby further improving the heat dissipation efficiency of the light-emitting component 200. At the same time, in this solution, the airflow introduced into the housing 100 through the air inlet 180 and discharged from the housing 100 through the air outlet 190 after heat exchange with the heat dissipation unit 320 experiences less resistance and smoother flow, thereby improving heat exchange efficiency while reducing wind noise.

[0062] To further reduce the resistance of the heat exchange airflow within the housing 100 and improve the heat exchange efficiency between the heat exchange airflow and the heat dissipation unit 320, a separate heat dissipation chamber 141 can be provided within the housing 100, allowing the heat dissipation airflow to exchange heat with the heat dissipation unit 320 within the separated heat dissipation chamber 141 within the housing 100. Specifically, see... Figures 2-3 In some embodiments, the receiving cavity 140 is provided with a first partition 160 and a second partition 170 arranged at intervals along a first direction X. The first partition 160 is disposed on the side of the second partition 170 near the light outlet 150 and the two are spaced apart from each other. The first partition 160, the second partition 170, and the housing 100 together define a heat dissipation chamber 141. In other words, the first partition 160 and the second partition 170 separate the receiving cavity 140 of the housing 100 into a separate chamber (i.e., the heat dissipation chamber 141) within the housing 100, and the receiving cavity 140 includes the heat dissipation chamber 141. The heat dissipation chamber 141 is located between the first partition 160 and the second partition 170. The air inlet 180 is located on one side of the housing 100 along the second direction Y, communicating with the heat dissipation chamber 141. The air outlet 190 is located on the other side of the housing 100 along the second direction Y, communicating with the heat dissipation chamber 141. Along the first direction X, both the air inlet 180 and the air outlet 190 are at least partially located between the first partition 160 and the second partition 170. The heat dissipation unit 320 is located inside the heat dissipation chamber 141. In this design, external air enters the heat dissipation chamber 141 through the air inlet 180 and exchanges heat with the heat dissipation unit 320 within the relatively smaller space of the heat dissipation chamber 141. On the one hand, the heat exchange between the heat dissipation unit 320 and the heat exchange airflow is more complete, resulting in higher heat dissipation efficiency. On the other hand, the heat exchange airflow is less likely to flow into other spaces within the housing 100, resulting in less airflow resistance and lower noise.

[0063] See Figures 2-4In some embodiments, the first partition 160 is located on the side of the second partition 170 near the light outlet 150. The receiving cavity 140 includes a light-emitting chamber 142 located on the side of the first partition 160 near the light outlet 150. The light-emitting component 200 is located in the light-emitting chamber 142. The heat-conducting part 310 passes through the first partition 160 and connects to the light-emitting component 200. In other words, the space between the first partition 160 and the light outlet 150 is the light-emitting chamber 142. The light-emitting component 200 is located in the light-emitting chamber 142, and the heat-conducting part 310 passes through the first partition 160, thereby guiding the heat of the light-emitting component 200 in the light-emitting chamber 142 into the heat dissipation chamber 141. In this scheme, since the first partition 160 separates the light-emitting chamber 142 and the heat dissipation chamber 141, compared with the scheme in which the heat dissipation chamber 141 is directly connected to the light outlet 150 and the light-emitting component 200 is located in the heat dissipation chamber 141, foreign objects are less likely to be guided to the light-emitting chamber 142 through the heat dissipation chamber 141, thus reducing the probability of damage to the light-emitting component 200 due to foreign objects entering the light-emitting chamber 142.

[0064] The specific shapes and arrangements of the first partition 160 and the second partition 170 depend on actual needs; they only need to define the heat dissipation chamber 141 together with the housing 100. See [link to documentation]. Figures 2-3In some embodiments, the housing 100 includes a first concave shell 110 and a second concave shell 120 connected to each other. The first concave shell 110 and the second concave shell 120 are arranged opposite each other along a second direction Y. An air inlet 180 is provided in the first concave shell 110 and an air outlet 190 is provided in the second concave shell 120. The first concave shell 110 has a first cavity on the side facing the second concave shell 120, and the second concave shell 120 has a second cavity on the side facing the first concave shell 110. After the first concave shell 110 and the second concave shell 120 are connected, the first cavity and the second cavity communicate with each other. The first partition 160 includes a first plate 161 and a second plate 162 arranged opposite each other along the second direction Y. The first plate 161 is connected to the first concave shell 110, and the second plate 162 is connected to the second concave shell 120. The second partition 170 includes a third plate 171 and a fourth plate 172 arranged opposite each other along the second direction Y. The third plate 171 is connected to the first concave shell 110 and is spaced apart from the first plate 161 along the first direction X. The fourth plate 172 is connected to the second concave shell 120 and is spaced apart from the second plate 162 along the first direction X. In this design, the first plate 161 and the third plate 171 can be integrally formed with the first concave shell 110, thereby reducing the overall number of components of the light-emitting module without increasing the mold volume when processing the first concave shell 110. Similarly, the second plate 162 and the fourth plate 172 can also be integrally formed with the second concave shell 120, thereby further reducing the number of components. After the first concave shell 110 and the second concave shell 120 are assembled, the first plate 161 and the second plate 162 are assembled together to form the first partition 160, and the third plate 171 and the fourth plate 172 are assembled together to form the second partition 170.

[0065] In other embodiments, the first partition 160 and the second partition 170 may both be complete plates. For example, the housing 100 may include an annular peripheral wall plate (i.e., the first concave shell 110 and the second concave shell 120 are integrally connected to form the peripheral wall plate). The first partition 160 and the second partition 170 are assembled into the peripheral wall plate through openings at both ends of the peripheral wall plate. In yet another embodiment, the housing 100 may also include a side plate and a concave shell connecting the side plate. The side plate and the concave shell together enclose the aforementioned peripheral wall plate. The first plate 161 and the second plate 162 are both assembled and connected to the concave shell or are both integrally connected to the concave shell.

[0066] See Figures 2-3In some embodiments, the housing 100 may further include an end shell 130. The first concave shell 110, the second concave shell 120, and the end shell 130 together enclose a receiving cavity 140. The end shell 130 is connected to one end of the first concave shell 110 and the second concave shell 120 along the first direction X. The end shell 130 is provided with the aforementioned light outlet 150. One end of the light guide 220 passes through the light outlet and is positioned on the end shell 130. The shape and size of the end shell 130 are designed according to actual needs to ensure a tight fit with the first concave shell 110 and the second concave shell 120.

[0067] See Figures 4-7 In some embodiments, the light-emitting component 200 includes a light-emitting element 210 and a light guide element 220. The light-emitting element 210 generates light, and the light guide element 220 guides the light out of the light port 150. The heat-conducting part 310 includes a heat-conducting block 311 and a first heat-conducting pipe 312. The heat-conducting block 311 is connected to the light-emitting element 210, and one end of the first heat-conducting pipe 312 is connected to the heat-conducting block 311, and the other end is connected to the heat dissipation part 320. In this solution, the heat-conducting block 311 is attached to the light-emitting element 210, thereby increasing the contact area between them and improving the heat exchange efficiency. The tubular first heat-conducting pipe 312 transfers the heat from the heat-conducting block 311 to the heat dissipation part 320, which reduces the overall space occupied by the heat-conducting part 310. The material of the first heat dissipation pipe can be determined according to actual needs. In this embodiment, the first heat dissipation pipe can specifically be a copper heat dissipation pipe.

[0068] To improve the heat exchange efficiency between the heat-conducting block 311 and the first heat-conducting pipe 312, see... Figures 4-7 In some embodiments, the heat-conducting block 311 has a groove 3111 on the side opposite to the light-emitting element 210, and one end of the first heat-conducting pipe 312 extends into the groove 3111 and fits against the groove wall of the groove 3111. In this design, the contact area between the first heat-conducting pipe 312 and the heat-conducting block 311 is larger, thereby making the heat exchange efficiency between the heat-conducting block 311 and the first heat-conducting pipe 312 higher. Specifically, in some embodiments, the groove 3111 can be arranged to penetrate the heat-conducting block 311 along a third direction Z, thereby facilitating the processing of the groove 3111. Further, the first heat-conducting pipe 312 can be arranged as a bent pipe, and both ends of the first heat-conducting pipe 312 are connected to the heat dissipation part 320. The bent part in the middle of the first heat-conducting pipe 312 extends into the groove 3111 and fits against the groove wall of the groove 3111. This design can increase the length of the pipe segment in contact with the heat-conducting block 311 and can also increase the number of paths used for heat conduction, thereby further improving the heat conduction efficiency.

[0069] In some embodiments, a thermally conductive filler (not shown) is used to fill the gap between the first heat-conducting pipe 312 and the groove wall of the groove 3111. This thermally conductive filler fills the gap between the first heat-conducting pipe 312 and the groove 3111, guiding the heat from the heat-conducting block 311 to the first heat-conducting pipe 312 through the thermally conductive filler. This solution can further improve the thermal conductivity between the heat-conducting block 311 and the first heat-conducting pipe 312. Specifically, the thermally conductive filler can be made of a high thermal conductivity material such as thermal grease or thermal tin to ensure efficient heat transfer and reduce thermal resistance. Furthermore, the shape and size of the groove 3111 can be optimized according to the bending angle and diameter of the first heat-conducting pipe 312 to maximize the contact area and heat conduction path, further improving overall heat dissipation performance. The thickness and distribution of the thermally conductive filler must be uniform to ensure uniform heat transfer. Additionally, the depth and width of the groove 3111 should match the bending radius of the first heat-conducting pipe 312 to avoid affecting the thermal conductivity due to excessive tightness or looseness. Through precise design, the heat exchange efficiency between the heat-conducting block 311 and the first heat-conducting pipe 312 can be further optimized, thereby improving the stability and reliability of the overall heat dissipation system.

[0070] See Figures 4-7 In some embodiments, the heat-conducting part 310 further includes a second heat-conducting pipe 313. One end of the second heat-conducting pipe 313 is used to collect heat from the light guide 220, and the other end is connected to the heat dissipation part 320. The second heat-conducting pipe 313 can be made of the same material as the first heat-conducting pipe 312 to ensure consistent heat conduction. The second heat-conducting pipe 313 rapidly transfers the heat generated by the light guide 220 to the heat dissipation part 320 through an efficient heat conduction path, further dispersing the heat and reducing the overall temperature. Its layout complements the first heat-conducting pipe 312, forming a dual heat dissipation mechanism, which significantly improves the heat dissipation effect. At the same time, since the second heat-conducting pipe 313 and the first heat-conducting pipe 312 are respectively connected to the same heat dissipation part 320, compared with the scheme where the first heat-conducting pipe 312 and the second heat-conducting pipe 313 are respectively connected to different heat dissipation parts 320, the number of heat dissipation parts 320 can be reduced, the structural design can be simplified, the manufacturing cost can be reduced, and the heat can be concentrated and processed, avoiding local overheating problems caused by uneven heat dissipation, further improving the heat dissipation efficiency and stability of the system.

[0071] See Figures 4-7In some embodiments, the skin care device 10 further includes a second heat dissipation component 400, which is a thermoelectric cooler, also known as a thermocouple, Peltier effector, or thermoelectric cooler. It is a cooling device based on the thermoelectric effect (especially the Peltier effect). This device effectively transfers heat during the cooling process through the Peltier effect, improving heat exchange efficiency. The second heat dissipation component 400 includes a cold surface 410 and a hot surface 420 facing each other. The cold surface 410 is attached to the light guide 220, and the hot surface 420 is attached to the second heat pipe 313. Through the Peltier effect, the cold surface 410 rapidly absorbs heat from the light guide 220, while the hot surface 420 transfers the heat to the second heat pipe 313, forming an efficient hot and cold cycle. This design not only enhances the local cooling effect but also optimizes the overall thermal management system, ensuring that the light-emitting component 200 maintains stable performance during long-term use and extending its service life.

[0072] See Figures 3-6 In some embodiments, the heat dissipation unit 320 includes a plurality of heat exchange fins 321 arranged at intervals along a first direction X. The first heat conduction pipe 312 includes a first tube body 3121, and the second heat conduction pipe 313 includes a second tube body 3131. Both the first tube body 3121 and the second tube body 3131 are disposed through each heat exchange fin 321. The projection plane is perpendicular to the second direction Y. The first tube body 3121 forms a first projection on the projection plane, and the second tube body 3131 forms a second projection on the projection plane. The first projection and the second projection do not overlap at least partially. In other words, when viewed along the second direction Y, the first tube body 3121 and the second tube body 3131 are at least partially staggered in space, so that there is no complete obstruction between the first tube body 3121 and the second tube body 3131. The heat exchange airflow entering from the air inlet 180 can evenly cover and flow through the surfaces of the two tube bodies, maximizing the heat exchange area and improving the heat dissipation efficiency. It should be noted that the first heat pipe 312 may include one first pipe body 3121 or multiple first pipe bodies 3121, and the second heat pipe 313 may include one second pipe body 3131 or multiple second pipe bodies 3131. Specifically, in this embodiment, both the first heat pipe 312 and the second heat pipe 313 are bent pipes, and both ends of the first heat pipe 312 and the second heat pipe 313 are connected to heat exchange fins 321. In this case, the first heat pipe 312 includes two first pipe bodies 3121, and the second heat pipe 313 includes two second pipe bodies 3131.

[0073] See Figures 3-6In some embodiments, the second heat pipe 313 and the first heat pipe 312 are spaced apart along the second direction Y, and the second heat pipe 313 is located on the side of the first heat pipe 312 away from the air inlet 180. In this scheme, the heat exchange airflow entering the housing 100 from the air inlet 180 first flows through the first heat pipe 312 and exchanges heat with it, and then flows through the second heat pipe 313 and exchanges heat with it. That is, the heat exchange airflow first absorbs the heat from the light-emitting element 210 connected to the first heat pipe 312, and then absorbs the heat from the light guide element 220 connected to the second heat pipe 313. Since the heat of the light-emitting element 210 is higher than that of the light guide element 220, the heat conduction requirement of the first heat pipe 312 is greater than that of the second heat pipe 313. Therefore, cooling the light-emitting element 210 first and then cooling the light guide element 220 can ensure the heat dissipation of the system is balanced and improve the overall heat dissipation efficiency.

[0074] See Figures 3-6 In some embodiments, when the first heat pipe 312 includes two first tube bodies 3121 and the second heat pipe 313 includes two second tube bodies 3131, the two first tube bodies 3121 and the two second tube bodies 3131 can be arranged in an alternating manner to form a multi-layered heat exchange structure, further increasing the heat exchange area and improving the heat transfer efficiency. Furthermore, viewed along the second direction Y, the two second tube bodies 3131 can be located between the two first tube bodies 3121, allowing the first heat pipe 312 to have a larger dimension along the third direction Z, thereby increasing the contact area between the first heat pipe 312 and the heat-conducting block 311, ensuring rapid heat conduction to the heat-conducting block 311, and further improving the heat dissipation effect.

[0075] Because the light-emitting element 210 generates a high amount of heat, and the second heat-conducting pipes 313 are spaced apart on one side of the light-emitting element 210, the heat from the light-emitting element 210 is easily conducted to the second heat-conducting pipes 313, thus affecting the heat dissipation of the light guide element 220. To prevent the heat from the light-emitting element 210 from being conducted to the second heat-conducting pipes 313, in some embodiments, a first heat insulation layer (not shown in the figure) can be provided on the side of the second heat-conducting pipe 313 facing the heat-conducting block 311. The first heat insulation layer can reduce the heat conduction from the first heat-conducting pipe 312 to the second heat-conducting pipe 313, reduce the heat conduction from the heat-conducting block 311 to the second heat-conducting pipe 313, and reduce the heat conduction from the light-emitting element 210 to the second heat-conducting pipe 313, thereby improving the heat dissipation efficiency of the second heat-conducting pipe 313 for the light guide element 220. The design of the first heat insulation layer can be adjusted in thickness and material according to actual needs to ensure efficient heat insulation without affecting the overall structural compactness, thereby optimizing the heat dissipation path and achieving optimal heat management configuration. The first insulation layer uses a material with low thermal conductivity. For example, the material of the first insulation layer can be ceramic fiber, silicone, asbestos, etc., which can effectively block heat conduction, ensure that heat is dissipated efficiently along the designed path, avoid heat cross-interference, and improve the heat dissipation stability of the system.

[0076] Because the second heat pipe 313 is close to the housing 100, and users need to hold the housing 100 when using the skin care device, a high temperature in the housing 100 can easily affect the user experience. Therefore, to prevent heat from the second heat pipe 313 from being conducted to the housing 100, in some embodiments, a second heat insulation layer (not shown in the figure) is provided on the side of the second heat pipe 313 facing the housing 100. The second heat insulation layer can reduce the heat transfer from the second heat pipe 313 to the housing 100, thereby reducing the surface temperature of the housing 100 and improving user comfort. The second heat insulation layer also uses a low thermal conductivity material, such as ceramic fiber, silicone, or asbestos, which can effectively isolate heat and ensure that the temperature of the housing 100 is controlled within a reasonable range. In other embodiments, a second heat insulation layer can also be provided on the side of the first heat pipe 312 facing the housing 100, thereby reducing the heat transfer from the first heat pipe 312 to the housing 100, further reducing the temperature of the housing 100 and improving the user experience.

[0077] See Figures 3-6In some embodiments, the second heat pipe 313 includes a second pipe body 3131, a third pipe body 3132, and an intermediate pipe body 3133. The second pipe body 3131 is connected to the heat dissipation part 320, the third pipe body 3132 is used to obtain heat from the light guide 220, and one end of the intermediate pipe body 3133 is connected to the second pipe body 3131 along the first direction X, and the other end is connected to the third pipe body 3132. The intermediate pipe body 3133 is bent and along the second direction Y, and the third pipe body 3132 is located on the side of the second pipe body 3131 away from the first heat pipe 312. In this solution, without increasing the volume of the housing 100, the second pipe body 3131 can be further away from the housing 100, thereby effectively reducing the heat conduction of the second pipe body 3131 to the housing 100, further reducing the temperature of the housing 100, and improving the user experience. Furthermore, the second insulation layer can be provided only on the side of the third tube 3132 facing the housing 100, so as to more accurately isolate heat, reduce the heat transferred from the third tube 3132 to the housing 100, and reduce the material used for the second insulation layer, thereby reducing material costs.

[0078] See Figures 3-6 In some embodiments, the skin care device 10 further includes an air supply assembly 500 disposed between the air inlet 180 and the air outlet 190 to generate an airflow flowing in the second direction Y. In some embodiments, the air supply assembly 500 may be located between the heat dissipation section 320 and the air outlet 190, so that the heat exchange airflow enters the housing 100 from the air inlet 180, first flows through the heat dissipation section 320, and then flows through the air supply assembly 500. In some embodiments, the air supply assembly 500 is located between the heat dissipation section 320 and the air inlet 180, so that the heat exchange airflow enters the housing 100 from the air inlet 180, first flows through the air supply assembly 500, and then flows through the heat dissipation section 320.

[0079] See Figures 1-4 In some embodiments, the dimension of the housing 100 along the third direction Z is greater than the dimension of the housing 100 along the second direction Y. In other words, the first direction X can be the length direction of the housing 100, the second direction Y can be the thickness direction of the housing 100, and the third direction Z can be the width direction of the housing 100. When the thickness dimension of the housing 100 along the second direction Y is smaller than the width dimension along the third direction Z, the airflow entering the housing 100 through the air inlet 180 has a shorter flow path within the housing 100, resulting in a shorter residence time for the heat exchange airflow, a lower temperature rise in the heat exchange airflow, and a larger temperature difference between the heat exchange airflow and the heat dissipation part 320, thereby achieving higher heat exchange efficiency for the heat dissipation part 320.
